적층 방향에 따른 3차원 격자구조의 응력방정식 정리 및 위상최적화 적용에 관한 연구

조성규 경기대학교 대학원 2023 국내박사

기존 가공 방식의 단점을 보완하는 적층 제조 방식은 다양한 제조 공정이 있다. 이 중 FDM 방식은 생산 장비와 재료값이 저렴하다는 상대적 장점이 존재한다. 또한 적층 제조 공정은 제품의 내부에 다양한 형태의 공동을 생성할 수 있다는 장점도 존재한다. 이는 동일한 외형에 동일한 재료를 사용한 제품임에도 다른 기계적 물성치를 나타낼 수 있다는 특징이 있다. 이에 최근까지 관련 연구가 활발하게 진행되고 있다. 하지만 적층 제조 과정, 특히 FDM 방식은 적층 방향에 수직인 방향의 힘에 취약하다는 단점이 존재하며, 적층 제조 후 원재료의 물성치보다 낮은 물성치를 나타내는 경향이 있다. 이를 보완하고자 내부에 일정한 형태의 3차원 격자 구조를 생성하여 단점을 보완하려는 연구가 많아지고 있다. 이에 본 논문에서는 3차원 격자 구조의 종류에 따라 상대밀도 대비 축 방향의 힘에 대한 응력의 변화를 실험을 통해 확인하고, 기존의 3차원 응력 상태에 적용되는 방식에 그대로 적용할 수 있도록 응력에 대한 수정계수를 구하였다. 마지막으로 적층 제조의 장점을 최대한으로 활용할 수 있도록 제품 내부에 3차원 격자 구조를 적절히 배치하는 위상 최적화를 통해 경량화와 나은 강성 설계를 목표로 연구를 진행하였다. The additive manufacturing method that compensates for the disadvantages of the existing processing method has various manufacturing processes. Among them, the FDM has the advantage of being inexpensive in production equipment and materials. In addition, the AM process has the advantage of being able to create various types of cavities inside the product. This is characterized in that it can show different mechanical properties even though it is a product using the same material in the same appearance. Therefore, in this paper, the change in stress for the force in the axial direction compared to the relative density according to the type of 3D lattice structure is confirmed through experiments, and the stress is analyzed so that it can be applied as it is to the existing 3D stress state. The modify coefficient was obtained. In order to make the most of the advantages of AM, research was conducted with the goal of designing light weight and better rigidity through topology optimization that appropriately arranges the 3D lattice structure inside the product.

열전 발전 소자의 최대 전력점 추적(MPPT) 회로 설계

조성규 충북대학교 2011 국내석사

We have proposed a maximum power point tracking (MPPT) circuit for thermoelectric generator (TEG) without digital controller unit. The proposed method is an analog tracking circuit by sampling half point of open circuit voltage without DSP or micro controller unit for calculating peak power point by iterative methods. The simulation results from the proposed MPPT circuit employing the boost cascaded-with-buck converter dealt with rapid variation of temperature and abrupt changes of load current have shown that the proposed method allows stable operation with high power transfer efficiency. The proposed MPPT circuit has an advantage of implementation cost and miniaturization than conventional MPPT algorithms due to the analog tracking circuit without micro-controller unit.

조성규 東國大學校 大學院 2004 국내석사

Wu Ju Tong(吳鞠通), one of the famous doctors in Qing(淸) dynasty, is a specialist of Wen Bing(溫病), also the branches of clinical medicine. Especially, the theory of San Jiao Bian Lun(三焦辨證) revealed by Wu Ju Tong(吳鞠通) had influence not only on Wen Bing(溫病), but also on chinese medical development. Here are summaries about his scientific ideas as beloved. 1. Wu's medical books are 『wen Bing Tiao Bian(溫病條辨)』, 『Yi Yi Bing Shu(醫醫病書)』, 『Wu Ju Tong Yi An(吳鞠通醫案)』, and here are the summaries of each book's xylographic book as beloved. First. 『wen Bing Tiao Bian(溫病條辨)』's block book, which was published first in 1836, is based on 'Wen Xin Tanh Ben(問心堂本)' published in the year of Gui You(癸酉), and is formed into three parties -'Jia Qing Gui You Ben(嘉慶 癸酉本)', 'Dao Guang 15 Nian Ben(道光 15年本)', and 'Dao Guang 16 Nian Ben(道光 16年本)'- in the future generation. Second. Yi Yi Bing Shu(醫醫病書)'s block book, which was published in 1831, couldn't be published at that time, so it is only left by transcription. Its existent block book is classified two systems 'Cao Jiao Ben(曹校本)' and 'Shen Jiao Ben(沈校本)'. Third. Wu Ju Tong Yi An(吳鞠痛醫案), which was published in 1833, couldn't be published at that time, so it is only left by transcription. Its existent block book is classified three systems: 'Qiu Ben Xi Tong(구본계통)', 'Jin Ben Xi Tong(金本系統)', 'Wang Ben Xi Tong(王本系統)'. 2. Wu's 'Wen Bing(溫病)' theory is developed from the base on the dialectic of the ancient scholars's 'Liu Jing(六經)', 'Wei Qi Ying Xie(衛氣營血)', 'San Jiao(三焦)'. And here are summaries about the origin of his scientific ideas. First. He tried Yin Zheng Mai Zhi(因證脈治) of Wen Bing(溫病) to be corresponded with the meaning of Huang Di Nei Jing(黃帝內經) that he thought Huang Di Nei Jing(黃帝內經) was the best scientific basis. Even he amended Wen Bing Tiao Bian(溫病條辨) when he realized it is not corresponded with Nei Jing(內經) after writing it. Second. Wu, basing on his clinic demonstration by studying Zhong Jing(仲景)'s learning, not only originated a system of Li(理), Fa(法), Fang(方), Yao (藥) about Wen Bing(溫病), but also developed Shang Han(傷寒)'s deficient theory portion. Third. He studied and perused Wu You Ke(吳又可)'s Wen Bing(溫病) theory, and chose only essences of Wu's his scientific viewpoint the and clinical experiences through the cause of disease, the progress of diseases, the herb medication, etc. So he succeeded to the essences throwing away unnecessariness. Fourth. by 'San Jiao(三焦)' Bian Zheng(辨證), Xie Tian Shi(葉天士)'s 'Wei Qi Ying Xie(衛氣營血)' Bian Zheng(辨證), and Zhong Jing(仲景)'s 'Liu Jing(六經)' Bian Zheng(辨證). He demonstrated his own Wen Bing(溫病) theory. specially he was succeeded from Xie Tian Shi(葉天士) like 'Ni Zhuan(逆傳)' of Wen Xie(溫邪), Fang Zheng(方證) of Wen Bing Tiao Bian(溫病條辨). so he completed Wen Bing(溫病) theory succeeded from Xie(葉)'s theory. 3. Wu widely gathered merits of many masters and presented his unique scientific opinion. Those contribute to the formation and the completion of the Wen Bing(溫病) study, and here are summaries. First. He united and penetrated many masters's theories about the cause of Wen Bing(溫病), and suggested the theory of 'San Yin Zhi Wen(三因致溫)'; normal and abnormal 'Fu Qi(伏氣)' and 'Si Tian Shi Ling Xian Xing Zhi Qi(司天時令現行之氣)', 'Li Qi(여기)' cause Wen Bing(溫病). Second. He originated the San Jiao Bian Zheng(三焦辨證) system through absorbing various masters' merits. First of all, he divided the position of disease into high and low, shallow and deep through the standard of 'San Jiao(三焦)'. Continuously, he distinguished between human organs and meridian through 'Liu Jing(六經)', and then also distinguished front and rear from inside and outside through 'Wei Qi Ying Xie(衛氣營血)'. He also stated Wen Xie(溫邪)'s the rules of change as Heng Xiang(橫向) and Zong Xiang(縱向), in addition, suggested the principle of the medicinal therapy as followed, "Zhi Shang Jiao Ru Yu(治上 焦如羽), Fei Qing Bu Ju(非輕不擧). Zhi Zhong Jiao Ru Heng(治中焦如衡), Fei Ping Bu An(非平不安). Zhi Xia Jiao Ru Quan(治下焦如權), Fei Zhong Bu Shen (非重不沈)." Third. He distinguished discriminations of disease between 'Wen Re(溫熱)' and 'Shi Re(濕熱)', divided the medicinal use into 'Gang Zao(剛燥)' and 'Rou Run(柔潤)'. That is also among Wu's Wen Bing(溫病) features. Fourth. He took a serious view of his Bian Zheng(辨證) and the principle of Yong Yao(用藥) about Wen Bing(溫病), connected his real clinical experience about Wen Bing(溫病) based on the ancients's experiences and theories. so he could That originated new treatments and available herb medications. Namely, he opened the field of the new remedy as the treatment of Xin Liang Qing Xuan (辛凉淸宣), insisted consistently the treatment of Qing Zi Pei He(淸滋配合) and Yang Yin Hu Ye(養陰護液), healed symptoms of Re Sheng Jin Shang(熱盛津傷) by the treatment of Gan Ku Hua Yin(甘苦化陰), applied the treatment of Zeng Shui Xing Zhou(增水行舟) and Yu Xie Yu Bu(寓瀉于補). Also he originated the herb medication of a type of Cheng Qi Tang(承氣湯), applied perfectly Xia Fa (下法), recovered Gan Shen Zhi Yin(肝腎之陰) by rearranging Fu Mai Zhu Fang(復脈諸方), used eliminating Shi Re(濕熱) by Xuan Fei Hua Qi(宣肺化氣). Fifth. He widely presented the contraindication theories of Wen Bing(溫病) treatments. These theories are the treatment, the herb medication, the dosage, the method of decocting a medicine and taking a medicine, a dietary treatment, ect. He realized that the result of wrong Wen Bing(溫病) treatments was serious, so tried to prevent contraindication treatments widened. 4. There are summaries of Wu's unique opinion about internal disease. First. He realized that the various disease from internal injury was caused or worsen by the mental stress, unsuitable foods, the problem of residental conditions. Especially he emphasized psychological treatments in case of the various disease from internal injury. Second. He emphasized on Bian Zheng Shi Zhi(辨證施治) through classifying Yang Xu(陽虛) and Yin Xu(陰虛) in Nei Shang Xu Sun(內傷 虛損). Also, he fully studied the position of disease in treating the symptom of Nei Shang Xu Sun(內傷 虛損), so he settled the treatments and the use of medicine. Third. He realized that Ben Ti(本體) of Wu Zang(五臟) became Yin(陰), and its operation became Yang(陽), Ben Ti(本體) of Liu Fu(六腑) became Yang(陽), and its operation became Yin(陰) in Ti Yong Guan Xi(體用系統) of Wu Zang Liu Fu(五臟六腑). Hence he remaked that there were the variety of Zang(藏), Xie(瀉) in Zang Fu Ji Neng(臟腑 機能), the difference of Tong(通), Shou(守) in Bu Fa(補法), and he divided the Bu Yi(補益) medicine use from Ti(體)·Yong (用) of Zang Fu(臟腑) into Yin Yang(陰陽) of Wu Zang Liu Fu(五臟六腑). Fourth. He realized that protecting Wei Qi(胃氣) is the key point of treatment, so stressed balancing and protecting Wei Qi(胃氣) unrelatedly with Xu Gong Shi(補虛攻實) in treatment. 5. Wu's orders and researches ahout Bian Zheng Lun Zhi(辨證論治) of Jing Bing(痙病) are as followed. First. Wu insisted that the theory of "Zhu Jing Xiang Qiang(諸痙項强), Jie Shu Yu Shi(皆屬于濕)" should be the error which was omitted or written wrongly in the transferring progress, and they belong to 'Feng(風)' all. Like this, he inspected closely the cause and the progress of diseases through the analysis of suspicious parts. Second. He not only detailed the cause and the progress of diseases but also made the diagnosis and the demonstration regular. Namely he classified nine kinds of Jing Bing(痙病) according to the cause of disease, demonstrated them in detail according to the combinative position of xie qi(邪氣), also generalized Si Gang(四綱) of Han(寒). Re(熱). Xu(虛). Shi(實) according to nine kinds of Jing Bing(痙病). Third. He tried to treat Jing Bing(痙病) fundamentally in the change of treatment, the remedy according to the symptoms. He put first Qu Xie(거사) in case of Liu Yin Zhi Jing(六淫 致痙), Wen Bu(溫補) in case of Jing(痙) of Xu Han(虛寒), and he insisted that Zi Yin(滋陰) should be the key point in Jing(痙) of Xu Re(虛熱). Fourth. He recognized the prevention in the step of Wei Jing(未痙) is the skill of 'Shang Gong(上工)'. He thought that the diseases could be treated by protecting Zheng Qi(正氣) and controlling Xie Qi(邪氣). And he cut the cause of Jing Bing(痙病) by the early treatment, searched the symptom and the cause of Jing Zheng(痙證), also tried to prevent the wrong treatment. 6. Here are the summaries of the his precise Bian Zheng(辨證) method, the accurate treatment and the composition of prescriptions about the stratagem of clinical medication as belows. First. He chose the treatment of 'Shi Shi Qing Yang(時時輕揚)' which was different from the decoction of common herb medication. These method strengthens the effect of treating Fei Wei(肺衛) by the xin liang(辛凉) medicine, and prevent Xie Qi(邪氣) from entering the inside deeply. Second. He emphasized the rule of 'Duo Bei Shao Fu(多備少服)' It was to stop taking medicine if the condition improved considerably. he tried to avoid the result of Zheng Xu Xie Xian(正虛邪陷). Third. He controlled mainly the dosage through 'Zhu Jian Zeng Liang(逐漸增量) and Yi Zhi Wei Du(以知爲度)' in case of Gong Fa Jun Ji(攻伐峻劑), and used repeatedly the method of Zhen Zhuo Chuai Mo(짐작췌마) to search the best effective dosage. Like this, he pursued the perfection in the added medicine dosage. Fourth. He was prudent in the method of Bian Zheng(辨證) and the dosage safety of Yong Yao(用樂) through a reagent medicine. He proceeded in case of possibilities and went back in case of difficulties in the clinical attitude. Fifth, Although Wu was not famlliar with the acupuncture, he demanded strongly the acupuncture and the combination treatment of medicines when he came in contact with difficult diseases every time. Even he treated the patient's disease with the other doctor familiar with the acupuncture. Sixth. He obtained the fast remedy effect with using simultaneously the external use as well as the internal use every time when he treated the symptoms of Wen Du(溫毒), Da Tou Wen(大頭瘟), Wen Du Hou Bi(溫毒喉痺), Yan Hou Zhong Tong(咽喉腫痛). Seventh. He combined appropriately merits of various forms, like Tang Ji(湯劑), San Jl(散劑), Wan Ji(丸劑) on the condition of disease, and used them in every kind of incurable symptoms. Eighth. He realized that infant's disease was closely related to a nurse. We can see the record that he treated his daughter's Dou Zheng(痘證) and treated her nurse together. Ninth. He made emesises stopped by Jiang Tang(薑湯) in case someone couldn't take remedy medicine because of emesises. 7. Here are summaries through wu's books about his modest scholarly attitude, the standing rule of the medical idea, achievements in the clinic experience, the true heart against patients, the recognition of society. First. He thought Yi De(醫德) serious, so he did volunteer work himself, also he emphasized that a man of ability should save the life and have the heart to relieve the world. Second. He recognized that those who will study medical science not only must have the heart to relieve the world, but also had the true effort of 'Ge Zhi Cheng Zheng(格致誠正)' by all means. Third. Wu emphasized throwing away the mind that one likes the convenience and dislikes complexity in the method reading medical books. And he forbade the badly trainned method of reading. Fourth. He indicated that the medical practice through the scientific discrimination could reach a stage of art. Fifth. He supplemented one-sidedness and excluded an abuse, and he was not in disorder but minute in originating his new theory. 8. There are summaries of researches reported for last 10 years about Wu's scientific valuation. First. In medical idea, wu gathered widely merits by otaining sincerely the ancients's teachings, and he emphasized the real clinical experience, brought to a conclusion by the whole statement, chose modestly the method of Shi Shi Qiu Shi(實事求是). Second. About San Jiao Bian Zheng(三焦辨證), wu constituted the Wen Bing (溫病) theory by San Jiao Bian Zheng(三焦辨證) and Wei Qi Ying Xie Bian Zheng(衛氣營血 辨證). Third. He applied San Jiao(三焦) to clinical study from a viewpoint of 'Yu(羽)', 'Heng(衡)', 'Quan(權)'. Fourth. Wu succeeded to and developed the theory of Xie tian shi(葉天士) for Zhi Fang(制方) and Yong Yao(用藥). Also he studied the nature of medicines by the combining the theory of San Jiao(三焦), excelled the ancients in the prescription part of 'Xie Zhong You Bu(瀉中有補), Qing Zhong You Xie(淸中有瀉), Xuan Tong Jie He(宣通結合)'. Fifth. Wu's standpoint about treating Wen Bing(溫病) by 'Gui Zhi Tang(桂枝湯)' was criticized like as Wang Meng Ying(王孟英). In regard of this, present scholars' standpoints are divided into the case of severe criticism, the case of the euphemistic discussion, the case of the praise. Sixth. Some scholars estimate that wu's scientific idea plays an important role, and they affirm the important value of his medical theory, but on the other hand they point out scientific defects. Wu set uP the new recognition and theory system about Wai Gan Re Bing(外感 熱病) after 1500 years Shang Han Za Bing Lun(傷寒雜病論) of Zhang Zhong Jing(張仲景) was established in Wai Gan Re Bing Shi(外感熱病史), and as above his scientific contribution is so great. I want to re-illuminate meaning of his book on the clinical medicine spot where is complicated and difficult and expect the future study Wen Bing(溫病).

자연테마여행객의 관광동기가 관광만족 및 재이용의도에 미치는 영향 : 관광지 이미지의 조절효과를 중심으로

조성규 동아대학교 대학원 2016 국내석사

현대 사회의 급속한 변화는 많은 사람들이 일상에서 벗어나 삶에서의 여유와 재충전을 원하게 되었으며, 이를 위한 하나의 수단으로서 관광이 자리 잡게 되었다. 또한 사회의 변화는 현대인들이 다양하고 까다로운 기호를 가지게 하였으며, 따라서 관광관련 업계의 기업측면에서 최고의 화두는 이러한 현대인의 욕구와 기대에 부응하는 차별화된 상품을 개발하는 것이라 볼 수 있다. 고객의 욕구와 기대를 충족하고자 하는 관광업계의 노력으로 최근 주목받고 있는 여행형태가 테마여행이며, 이는 사회적 변화와 고객의 니즈(needs)를 고려한 여행의 형태로서 참여한 고객의 욕구를 충족시키고 여행참여에 대한 동기의 높은 달성이 가능하게 함으로 타 여행형태에 비하여 여행을 통한 높은 만족도를 갖게 하므로 사회변화 움직임의 흐름과 함께 지속적인 성장이 이루어질 것으로 전망된다. 하지만 현재 테마여행에 관한 학술적 연구는 상당히 부족한 상태이며, 고객중심사고의 여행형태인 테마여행의 성숙한 발전을 위하여 테마여행에 참여하는 테마여행객들의 관광행동에 관한 연구가 절실히 필요한 상태이다. 이에 따라, 본 연구는 테마여행의 여러 유형 중 자연을 주테마로 한 자연테마여행상품에 참여하는 자연테마여행객의 관광동기가 관광만족, 테마여행사의 재이용의도에 미치는 영향을 파악하며, 관광지이미지가 관광동기와 관광만족 관계 간 조절효과를 가지는지를 연구를 통하여 규명하였다. 본 연구에서는 관광동기를 ‘휴식/일탈’, ‘자기실현’, ‘지적추구’, ‘미적추구’ 총 4가지로 나누어 측정하였으며, 관광동기가 관광만족, 재이용의도에 어떠한 영향을 미치는지와 관광지에서 자연테마여행객이 느끼는 관광지이미지에 대하여 ‘인지적 이미지’, ‘정서적 이미지’ 두 가지로 나누어 측정하여 관광지 이미지로 인한 관광동기와 관광만족 간의 관계에서의 조절효과의 여부를 검증하였다. 본 연구는 각 개념에 대한 선행연구를 바탕으로 연구모형을 설정하였으며, 설문조사는 2016년 1월부터 2016년 2월 까지 강원권 지역의 자연테마여행상품에 참여한 자연테마여행객을 대상으로 여행을 마치고 하차지로 향하는 교통수단인 버스 내에서 실시하였다. 총 307부의 설문지를 배포하여 297개의 유효한 설문지를 회수하였으며, 이를 통하여 실증분석을 실시하였다. 실증분석을 통한 연구결과는 다음과 같다. 첫째, 관광동기 중 ‘휴식/일탈’, ‘자기실현’, ‘미적추구’가 관광만족에 영향을 미치는 것으로 나타났으며, 테마여행사의 재이용의도에는 관광동기 중 ‘휴식/일탈’, ‘지적추구’가 영향을 미치는 것으로 나타났다. 둘째, 자연테마여행상품에 참여한 자연테마여행객의 관광만족은 테마여행사의 재이용의도에 긍정적인(+) 영향을 미치는 것으로 나타났다. 셋째, 자연테마여행객의 관광동기와 관광만족 간에 ‘미적추구’와 정서적 이미지의 상호작용항이 긍정적인(+) 조절효과를 가지는 것으로 나타나 정서적 이미지가 부분적으로 유사조절효과가 있음을 규명하였다. 본 연구를 통하여 자연테마여행객의 관광동기가 관광만족, 테마여행사의 재이용의도에 영향을 미친다는 점과 관광만족이 테마여행사의 재이용의도에 영향을 미친다는 점을 실증분석을 통하여 입증하였으며, 정서적 이미지가 ‘미적추구’의 관광동기를 가진 테마여행객에게 긍정적인(+) 조절효과로 인하여 높은 관광만족을 느끼게 한다는 결과를 실증분석을 통하여 도출하였다. 이를 통하여 자연테마여행객의 관광동기, 관광만족, 테마여행사의 재이용의도에 관한 관광행동분야의 시사점과 특히나 ‘지적추구의 관광동기를 가지고 참여한 자연테마여행객을 위하여 상품구상 시 관광지 이미지의 정서적 이미지를 고려한 상품개발이 효과적이다.’ 라는 세부적인 상품구상의 가이드라인을 시사한다.

ABSTRACT A Study on the Effects of the CEO and Industry Environment Characteristics on Value Innovation Strategy and Business Performance of Small and Medium sized Enterprises, and Development of Supportive Management Performance Evaluation System Sung-Kyu CHO Department of Management of Technology Graduate School of Management of Technology Supervised by Professor Ph.D. Jong-Won LEE In this study, the relationship between CEO characteristics, industry characteristics and value innovation strategies, value innovation strategies, and the management performance of 253 small and medium sized businesses operating in Korea as of September 2018 were studied. In order to collect data, using judgment sampling method, online questionnaires were distributed and 232 copies of survey results were collected via e-mail, Naver Band, and KakaoTalk, which were then analyzed using SPSS 25 statistical package. According to the result of hypothesis verification, the relationship between CEO characteristics and value innovation strategy proved the risk taking tendency, management competency, and mindset among CEO’s characteristics had a significant influential relationship on product innovation, which is technology innovation. Among the CEO’s characteristic, openness to risk and management competency showed significant influential relationship for business model innovation. However, only factor that positively influenced process innovation among CEO’s characteristic was management competency from value innovation strategy. In regards to the relationship between industry characteristics and value innovation strategy, environmental uncertainties among industry characteristics had a positive influence on product and business model innovation, while competitive intensity showed insignificant influential relationship. However, competitive intensity in industry characteristics showed significantly positive influential relationship in process innovation. The effect of CEO’s characteristics, industry characteristics, and value innovation strategy on relationship between small and medium sized businesses showed that only management competency and mindset among CEO’s characteristics showed positive influential relationship in the performance. Product innovation and process innovation from value innovation strategy only showed positive influence on the performance of small and medium business. Among industry characteristics, environmental uncertainties and competitive intensity had no significant influence on the business performance of small and medium sized companies. Upon verifying mediated effect of value innovation strategy in regards to the relationship between CEO’s characteristics and business performance of small and medium sized businesses, risk taking tendency, management competency, and mindset among CEO’s characteristics showed positive mediated effect through value innovation strategy’s product innovation, process innovation, and business model innovation. Therefore, upon studying the relationship between CEO’s characteristics, industry characteristics, and value innovation strategy; relationship between value innovation strategy and small and medium sized business’s performance, from the relationship between CEO’s characteristics and value innovation strategy; the CEO who possesses risk taking tendency, management competency, and mindset is fit for product innovation, the CEO who possesses risk taking tendency and management competency is fit for business model innovation, and for process innovation, the CEO should possess management competency over risk taking tendency and mindset. The relationship between industry characteristics and value innovation strategy is likely to find a resolution for management crisis to adopt or develop value innovation in order to sensitively respond to changes to management environment arising from environmental uncertainties. Due to these reasons you can actively and aggressively carry forward product innovation and business model innovation. Environmental factors like competitive intensity of the industry are affected according to the amount of process innovation. CEO’s characteristics, industry characteristics, and value innovation strategy all are related to performance of small and medium sized businesses, but in order to improve business performance, small and medium sized company must push forward management competency and mindset among CEO’s characteristics and also product innovation and process innovation among value innovation strategies. Upon verifying mediated effect of value innovation strategy in regards to relationship between CEO characteristics and business performance of small and medium sized businesses, among CEOs who possess CEO characteristics of risk taking tendency, management competency, and mindset should actively promote product innovation, process innovation, business model innovation’s value innovation. The mediating effect of the value innovation strategy on the relationship between the characteristics of the industry characteristics and the management performance of small and medium sized businesses was not significant. Competition intensity and environmental uncertainty, which are the external environment of small and medium sized businesses, are difficult to predict due to their inability to be controlled or managed. Therefore, there is a limitation in verifying the impact of small and medium sized businesses on management performance. The results of this study suggest that small and medium sized companies that lack both human and material resources compared to large conglomerates, in order for them to efficiently prepare and react to external factors, the study highlights the importance of CEO’s competency. Though CEOs of small and medium sized businesses cannot have all the required competencies, the lack of competencies should be overcome through various training activities and by creating a management environment that can assist the CEO by recruiting managers capable of supplementing the lack of competencies. It is especially difficult for small and medium sized companies to carry out new value innovation strategies while taking risks because of insufficient resources, lack of organization. Willingness to take new challenges with positive thinking is also difficult in such circumstances. CEOs who possess managerial competencies that are fit for such small and medium sized companies in hardship showed significant results in executing and enhancing value innovation strategy and business performances. 국문 요약 본 연구에서는 2018년 9월 현재 우리나라 중소기업을 운영하고 있는 232개 중소기업을 대상으로 CEO특성 및 산업환경 특성과 가치혁신전략 간의 관계, 가치혁신전략과 중소기업의 경영성과 간의 관계를 연구하였다. 자료수집을 위해 설문지법을 적용하였다. 구글 온라인 설문지를 e메일, 네이버 밴드, 카카오톡으로 배포하고 232부를 회수하였으며, 수집된 데이터는 SPSS.25 통계패키지를 이용하여 분석하였다. 가설검증 결과 CEO특성과 가치혁신전략 간의 관계는 CEO특성 중 위험감수성향과 관리적 역량, 마인드셋은 기술혁신인 제품혁신에 모두 긍정적인 유의한 영향관계를 보여 주었다. CEO특성 중 위험감수성향과 관리적 역량은 비즈니스모델혁신에 긍정적인 유의한 영향관계를 보여 주었다. 하지만 가치혁신전략 중 프로세스혁신에 긍정적인 영향을 준 것은 CEO특성 중 관리적 역량 뿐이었다. 산업환경 특성과 가치혁신전략 간의 관계는 산업환경 특성 중 환경불확실성은 제품혁신과 비즈니스모델혁신에 긍정적인 유의한 영향관계를 보여 주었으며, 경쟁강도는 유의하지 않은 영향관계를 나타냈다. 하지만 산업환경 특성 중 경쟁강도는 프로세스혁신에 긍정적인 유의한 영향관계를 보여 주었다. CEO특성, 산업환경 특성, 가치혁신전략이 중소기업의 경영성과 간의 관계는 CEO특성 중 관리적 역량과 마인드셋만 중소기업의 경영성과에 긍정적인 유의한 영향관계를 보여 주었다. 가치혁신전략 중 제품혁신과 프로세스혁신만 중소기업의 경영성과에 긍정적인 유의한 영향관계를 나타냈다. 산업환경 특성 중 환경불확실성과 경쟁강도는 중소기업의 경영성과에 유의한 영향관계가 발견되지 않았다. CEO특성과 중소기업의 경영성과 관계에 대한 가치혁신전략의 매개효과 검증결과 CEO특성 중 위험감수성향, 관리적 역량, 마인드셋은 가치혁신전략 중 제품혁신, 프로세스혁신, 비즈니스모델혁신을 통해서 모두 긍정적인 유의한 매개효과가 나타났다. 따라서 CEO특성 및 산업환경 특성과 가치혁신전략 간의 관계, 가치혁신전략과 중소기업의 경영성과 간의 관계를 연구한 결과 CEO특성과 가치혁신전략과의 관계에서 제품혁신은 위험감수성향, 관리적 역량, 마인드셋을 가진 CEO가, 비즈니스모델혁신은 위험감수성향, 관리적 역량을 가진 CEO이며, 프로세스혁신을 보다 활발하게 수행하기 위해서 CEO는 위험감수성향 및 마인드셋 보다는 관리적 역량을 가져야 한다고 할 수 있다. 산업환경 특성과 가치혁신전략 간의 관계는 환경불확실성의 경영환경변화에 민감하게 대응하기 위해 가치혁신을 채택하거나 개발함으로써 경영위기에 대한 대안을 찾을 가능성이 높다고 할 수 있다. 이런 이유로 제품혁신과 비즈니스모델혁신을 보다 활발하고 과감하게 추진한다고 할 수 있다. 산업환경 특성의 경쟁강도와 같은 외부요인은 프로세스혁신의 추진 정도에 따라 영향을 받는다고 할 수 있다. CEO특성, 산업환경 특성, 가치혁신전략이 중소기업의 경영성과 간의 관계는 중소기업의 경우 경영성과를 높이기 위해서 CEO특성 중 관리적 역량, 마인드셋 그리고 가치혁신전략 중 제품혁신, 프로세스혁신을 보다 적극적으로 추진하여야 한다고 할 수 있다. CEO특성과 중소기업의 경영성과 관계에 대한 가치혁신전략의 매개효과 검증결과, CEO특성 중 위험감수성향, 관리적 역량, 마인드셋을 가진 CEO가 제품혁신, 프로세스혁신, 비즈니스모델혁신의 가치혁신전략 모두를 보다 적극적으로 추진할 필요가 있다. 산업환경 특성과 중소기업의 경영성과 관계에 대한 가치혁신전략의 매개효과 검증결과 모두 유의하지 않은 매개효과가 나타나 중소기업 외부 환경인 경쟁강도와 환경불확실성은 통제나 관리가 불가능하여 예측이 어려워 중소기업의 경영성과에 영향을 검증하는 부분에 한계가 있다고 본다. 본 연구의 결과는 대기업에 비해 인적자원 및 물적자원이 부족한 중소기업은, 부족한 인프라를 효과적으로 대비하고 또한 외부 경영환경에 대응하여 중소기업의 경영성과에 기여하기 위해서는 CEO의 역량이 중요하다는 것을 시사한다. 중소기업의 CEO가 모든 역량을 갖출 수는 없지만 부족한 역량은 다양한 역량 강화교육을 통해 보완을 하고 부족한 역량을 지원해줄 수 있는 관리자를 채용하여 CEO를 보좌할 수 있는 경영환경을 조성해서 극복해야 할 것이다. 특히 규모가 적은 중소기업의 경우 자원이 부족해 위험을 감수하면서 새로운 가치혁신전략을 추진하기가 어렵고, 조직 또한 부족해서 긍정적인 생각만으로 새로운 도전을 하고자 하는 의지 또한 어렵다. 이러한 어려운 중소기업의 경영환경에 맞는 관리적 역량을 보유한 CEO가 가치혁신전략 실행에 유의한 결과를 보여 주며 중소기업의 경영성과 또한 유의한 결과를 보여 주었다.

취약한 인터넷 환경에서 IP 역추적 기술에 기반한 안전한 메신저 피싱 대응방안

조성규 숭실대학교 2014 국내박사

현재 우리나라의 경우 인터넷 환경의 급속한 발전 및 네트워크 인프라의 확충에 따라 컴퓨터를 이용해 상대방과 통신하기 위한 다양한 도구들이 많이 발전하고 있으며, 특히 PC 환경 에서는 이메일 보다 실시간으로 상대방과 대화할 수 있는 메신저를 사용하는 것이 보편화되어 있다. 이러한 메신저 사용의 편리함에 따라 기업들에서는 자체 개발한 메신저를 사용해 업무에 적용하는 사례들이 많아졌으며, 우리나라 인터넷 사용자의 약 48.5%가 메신저를 사용하고 있다는 통계도 보고되고 있다. 하지만 인터넷 환경의 편리함을 악용한 해킹 기법들이 발전 하면서 타인의 계정을 사용하여 메신저에 접속한 후 등록된 지인들에게 금품을 요구하는 등의 메신저 피싱 사기 사례가 끊이지 않고 증가하고 있으며, 메신저를 이용해본 사용자라면 한번 씩 경험해 볼 만큼 사기 사례가 빈번하게 발생하고 있는 실정이다. 이러한 메신저 피싱 사기의 경우, 정상 이용자가 피싱임을 인식하고 공격자의 IP 주소를 추적한다 할지라도, 범죄자들은 자신의 IP 주소를 속이기 위해 다양한 방법을 활용하여 실제 접속한 IP 주소를 숨기기 때문에 검거하는데 많은 어려움이 따르고 있다. 그러므로, 이와 같은 메신저를 이용한 사기에 노출되지 않기 위해서는 사전에 충분히 금전을 요구하는 상대방에 대한 검증을 하는 절차가 필요하며, 메신저를 개발 하는 공급사들도 메신저 피싱 사기를 탐지 및 예방할 수 있는 기능을 개발하여 보급하는 것이 필요한 상황이다. 본 논문에서는 메신저를 사용하는 이용자들이 실시간으로 대화하고 있는 상대방이 정상적으로 접속한 사용자인지를 판별할 수 있도록, Real IP 역추적 기법을 이용하여 범죄자의 Real IP 주소를 추출한 후 사전에 이용자들에게 피싱 시도에 대해 경고할 수 있는 방안에 대해 제시하고자 한다. 제시한 방안을 메신저에 적용할 경우, 범죄자가 국내 또는 해외에서 접속한 IP 주소를 변조하여 메신저를 이용한다 할지라도 범죄자의 원천 IP 주소를 추출할 수 있으므로 사전에 메신저 피싱 사기에 대처하는 것이 가능하여 진다. With the rapid advancement of the Internet environment and expansion of network infrastructure, various tools are being developed to communicate with others using computer in South Korea, and the uses of messengers in which users can talk with others in real time rather than e-mail are getting more widespread in a PC environment. With this convenience of using messengers, enterprises are gradually applying a messenger developed on their own to their businesses while there is a report on a statistic that approximately 48.5% of the South Korean users of the Internet are using a messenger. Yet, as hacking techniques abusing the convenience of the Internet environment are developing, cases of messenger phishing scams, e.g. logging on to a messenger using another person’s account and demanding money and valuables from the registered acquaintances continue increasing, and fraud cases occur so frequently that any users who have used a messenger service might have experienced at least once. There are lots of difficulties in arresting an attacker of such a messenger phishing scam since the criminal uses various methods to cheat on his or her real IP address actually used for connection even if a normal user recognized phishing and traced the IP address. Thus, so as not to be exposed to such a fraud using a messenger, a procedure of sufficiently verifying the other party who demands money in advance is necessary, and also, it is necessary for the suppliers developing messengers to develop and supply features to detect and prevent messenger phishing scams. This paper will attempt to propose a measure to extract the criminal’s real IP address by tracing back his or her real IP and give users warning of a phishing attempt so that the messenger users can distinguish whether the other party with whom they are talking in real time is a normally connecting user. Applying the proposed measure to a messenger will be able to extract the criminal’s source IP address so as to allow the users to cope with messenger phishing scams beforehand even if he or she uses the messenger falsifying the IP address used for connection from home or abroad.

디젤機關에 있어서 煤煙再生用 電氣加熱裝置의 性能特性에 관한 硏究

조성규 경상대학교 대학원 2006 국내석사

The purpose in this study is to develop an electrical heater system equipped with diesel particulate filter(DPF) or diesel oxidation catalyst(DOC) for regenerating soot forcibly in diesel engines. As the first step, in this paper, the electrical heater system is uniquely designed and manufactured to set up at the exhaust pipe. And then the effect of electrical heater on performance characteristics such as fuel economy, heat release rate and exhaust emissions under four kinds of engine loads are investigated by a single cylinder, four cycle, direct injection, water-cooled and agricultural diesel engine operating at three kinds of engine speeds. The air supplier to feed oxygen needed for the regeneration and automatic temperature controller to keep up the constant temperature are set up in front of electrical heater system. Experimental conditions are the temperature of electrical heater and the amount of air injection. It is found that the brake specific fuel consumption rate with the electrical heater system is a little raised compared with no heater system, and the cylinder pressure and the rate of heat release are both in a similar value regardless of heater system. Results also show that soot and THC emissions are decreased, and NOx emissions are slightly decreased as the temperature of electrical heater and the amount of air injection are elevated. CO emissions are also decreased until the temperature of electrical heater is raised to 450℃, but increased at 550℃. CO2 emissions, however, are increased as the temperature of electrical heater is raised.

This thesis is objected to compare and analyze the Politics Education contents through the conservative function and the innovative function of the social function of education in between the 『politics』 area of the 『Politics·Economics』, a highschool textbook which has been published for the 5th curriculum announced on October 31, 1988, and the politics education contents of the 『Politics』, another highschool textbook which has been using currently during the 6th curriculum announced on October 30, 1992, and also to study on which social functions, the politics education contents stress. It is believed worthwhile to analyze the changing feature of the politics education through a comparison of the politics education contents in the 5th and the 6th curriculum. We aimed to lighten <What kind of social function does the politics education of sociology curriculum accomplish?>, <How does the education contents included in the politics textbook reflect the social function> and at the same time, aimed to look out over the suggestive point which is requested to grope for a right direction of the politics education contents in the textbook in the future. Of the sociology curriculum which takes a major task from understanding and verifying various phenomenon occurred in social life, the politics education occupies a big position. Because the social life in present time is to be developed through the medium of politics and it is greatly depending on an existing pattern of politics. A human being comes to grow into a political existence by way of learning the political culture of the society belonging to itself and a society needs a politics education to sustain the fundamental structure of its society and develop it continuously. Although it is considered from a different standpoint, the purpose of politics education could be essentially said to 『Democratic Citizenship』. This country takes 『Democraticism』 as an ideology for education, and 『Training Democratic Citizen』, 『Forming Democratic People』 corresponding to democratic thoughts, attitude, faith and behaving style etc come to be a general goal of education in school However, in spite that the politics education has been conducting from a point of educating Democratic Citizen, it was true that the politics education caused a conceptional confusion and has not been carried out consistently, having a structural contents. And as it is seen in the theses that have studied a relationship between the governing ideology for a country and education, it raises a doubt that the overly stressing a conservative function for only maintaining the current constitution tends to selectively emphasize specific contents such as social harmony and order etc under the country's intentional purpose, and tends to exclude criticism against the contents choking up a reform as well as public order and discipline. What is the social function stressed in the politics education is very critical in leading to a right direction of the politics education. If the politics education is understood to perform a conservative function which makes each member of the society being taught of the organization's culture and discipline and maintaining the society, we may judge whether the function of the politics education is conservative or innovative, depending on whether its putting stress on maintaining the society or change. In general, the society falls in chaos when it is neglecting the conservative function, and falls in depression when it is neglecting the innovative one of the politics education From this point of view, it needs an analyzing and comparison of the politics textbooks' education contents as a study if what is the desirable direction of politics education, which function is the politics education stressing, should be very important for young generation who will be responsible for the future. To accomplish its purpose, in the Chapter II, have stated a functional point of view, looked about the necessity of usefulness and harmony between the conservative and innovative function for politics education, and also, briefly studied the process of undergoing changes in the sociology curriculum until now. In the Chapter III and IV, have enlightened a basis and method for content analysis of the politics textbook in the highschool and presented a frequency comparative analysis and a content comparative analysis in each education area. Finally in the Chapter V, have suggested a desirable direction to be expected in the politics education and made a summary and concluded.

광섬유 센서를 이용한 WIM Mold Package 에 관한 연구

조성규 호서대학교 벤처전문대학원 2002 국내석사

In our research, we focused in optimization of WIM Mold which is used in high speed scale system using fiber optic sensor. The problem of Mold is the non-linearity in the relation of weight and variability at the Mold pad. It can be compensated by remolding the structure and thermal process. Also, for the easiness of movement and installation, the structure remolding is done to I shape. It makes the whole Mold incline 0.154 approximately. This value is small enough so that we can regard it the optimized Mold. This research is experimented indoor and outdoor as well. We conclude that our enhanced WIM Mold is adequate to be used in high speed scale system. But because of the measuring error while we are scaling the weight in the WIM system, it is a little bit difficult to be installed in the field right away. In our future research, we are going to stabilize the system and we will be able to apply it to the new system which are a combination of existing scale system and speed measuring system.
