박광수 서울시립대학교 2011 국내석사

최근 국내 건설산업의 대형화, 복잡화, 전문화 추세에 따라 검사중심의 감리시장은 축소되는 반면, 품질, 비용, 공기 등의 목표를 종합적으로 관리할 수 있는 건설사업관리(CM ; Construction Management) 시장은 점차 활성화되고 있다. 이러한 환경 속에서 기존의 감리회사는, 사용자 요구에 대한 만족과 장기적인 발전을 충족시키기 위하여 부가가치가 높은 CM시장에 진입하지 않을 수 없다. 건설환경 패러다임의 변화를 인지하지 못하는 감리회사는, 심화되고 있는 시장경쟁체제에서 뒤처지게 되며, 시장에서 생존하기 위하여서는 회사의 CM 역량을 강화해야 한다. 본 연구에서는 기존의 감리회사에서 CM업무를 원활하게 수행하기 위하여, 감리 및 CM사례와 업무내용에 대한 비교분석을 통한 감리회사의 CM역량 강화방안을 제안하였다. 본 연구는 다음과 같이 진행되었다. 1) 역량 강화방안의 적용가능한 정부의 분석 자료와 문헌, 관련 법규 및 연구논문 고찰을 통한 감리와 CM의 개념 및 현황을 파악하였다. 2) 국내 감리/CM사례 조사와 업무내용을 비교․분석하여 감리회사에서 CM업무 수행상의 문제점 및 시사점을 도출하고, 이에 대한 개선방향을 제시하였다. 3) 설문 및 면담조사를 통한 CM능력 향상과 역량강화의 필요성 및 개선방안을 도출하였다. 4) CM분야 전문가 면담을 통해 본 연구에서 제안한 CM사업 수행을 위한 역량 강화방안의 유효성을 검증하였다. 본 연구를 통하여 도출된, 감리회사에서 CM업무 수행을 위한 역량 강화방안을 CM능력 향상을 위한 요소기술, 감리회사 차원의 개선방안 및 산업계 차원의 개선방안으로 분류하여 제시하였다. 역량 강화방안의 주요 내용은 다음과 같다. 1) CM의 업무의 효율화 및 CM의 역할을 극대화하기 위해서, CM능력 향상을 위한 요소기술인 VE 및 시공성 분석, 클레임 및 분쟁해결, 파트너링, 발주관리에 대한 CM 역량을 키워야 한다. 2) 감리회사 차원의 개선방안으로서, CM 조직체계와 CM 품질시스템 의 활성화를 위해 품질경영시스템으로 정착되어야 하며 현장점검시스템 구축 및 다양한 CM의 기술개발이 필요하다. 3) 산업계 차원의 개선방안으로서, 우수한 인적자원을 효과적으로 개 발, 육성하기 위하여 전문적인 교육훈련 및 경력개발, CM과 관련 한 인프라 구축 그리고 CM용역 대가의 개선 및 CM용역 입찰실적 제한에 대한 제도적인 개선이 필요하다. 본 연구에서 제안한 CM업무 수행을 위한 역량 강화방안은 감리회사가 CM시장으로 진입하기 위한 가이드라인으로서 회사의 수준 및 시스템을 향상시킬 수 있는 계기가 될 것으로 기대된다. PQ 입찰 및 투자비용에 관한 부분은 본 연구의 범위에서 제외하였다. 향후 본 연구의 결과가 감리회사에서 실질적이고 가치가 있는 CM사업 수행을 위한 역량 강화방안이 되도록 본 연구에서 다루지 못한 제도적인 측면의 PQ 입찰 및 회사의 투자비용 등 추가적인 연구가 필요할 것으로 판단된다. Recently, domestic construction industries are tending to be large, complex, and specialized, so that examination-oriented supervision market is being reduced. In response to this challenge, the construction management market to comprehensively achieve targets for quality, cost, and construction duration is actively growing. Under such circumstances, existing construction inspection companies have to enter the construction management (CM) market for their long-term development and to satisfy their customers’ needs. Construction inspection companies that do not recognize changes in the construction business environment paradigm fail to follow the market’s competition system. To survive in such market, it is necessary to strengthen critical technologies to improve a company’s CM abilities. Thus, this study compares and analyzes the works in the supervision and CM cases and proposes important technologies to improve CM capabilities to smoothly perform CM businesses. The major contents of this study are as follows. (1) This paper studies the concept and current status of supervision and CM through analytical data from the government, a literature study, and a study on the relevant laws and regulations that can be applied to enhance CM capabilities. (2) This study compares and analyzes domestic supervision/CM cases and work details, induces problems and implications occurred in the process of performing CM projects by construction inspection companies, and proposes directions for improvement. (3) This study identifies necessities in improving CM abilities and CM companies’ capabilities through a survey and interviews. (4) Through interviews with construction supervision and CM experts, this study verified the effectiveness of the capability strengthening methods for the performance of CM projects. The measures to improve CM project performance capabilities that are proposed in this study are categorized into improvement measures in relation to the critical technologies and supervision companies and the measures oriented to the industry. The measures to strengthen the abilities are as follows. 1) To maximize efficiency of CM business and the role, CM abilities regarding critical technologies of value engineering (VE), constructability analysis, claim and disputes resolution, partnering and order management. 2) Oriented to supervision companies, quality management system should be settled down to activate CM organization systems and CM quality systems and implementation of field control system and various CM technologies development are necessary. 3) As industry-oriented improvement measures, specialized training, education and career path development, implementation of CM oriented infrastructure, improvement CM service fee and systematic improvement of the limit of the previous experiences to join CM service bidding in order to effectively develop and cultivate superior human resources. The measures to strengthen abilities to improve CM business proposed in this study are guidelines for supervision companies to enter into the CM market and they are expected to give an opportunity to improve the company’s standards and systems. There is a limit in this study with respect to the PQ bidding and investment cost, so that it was removed from this study. To make this study useful in identifying actual measures to improve the capabilities of companies to perform substantial and valuable CM projects in Construction inspection Companies , it seems necessary to conduct further studies on relevant systems, including on PQ bidding and the company’s cost of capital, etc.

CFD 해석 기반 CVD Gas Box에 대한 폭발위험장소 설정의 타당성 검증

박광수 한국교통대학교 글로벌융합대학원 2022 국내석사

CVD 설비는 밀폐형 Gas Box 내에 암모니아, 실레인, 디실레인, 디클로로실란, 포스핀, 암모니아, 수소 등 인화성 가스를 취급하고 있다. 따라서 산업안전보건법에 따른 공정안전보고서 제출 대상이며 한국산업표준(KS C IEC 60079-10-1)에서 정하는 기준에 따라 폭발위험장소를 설정하고 종별에 적합한 방폭형으로 설치해야 한다. CVD 설비의 Gas Box는 상시 배기시스템과 Gas Monitoring System 등 다양한 인터록으로 구성되어 있으며, 무중단 운영에 따른 상시 가스 누출검사를 해야한다. 또한 CVD 설비는 세계 반도체 장비·재료협회에서 규정한 SEMI 규정에 따라 제작 및 인증을 받은 설비이다. 이와 같이 CVD 설비는 인터록 시스템과 세계적으로 사용되는 인증을 받았으나, 가스에 대한 최소 저장량의 기준이 없어 가스를 저장·공급하는 설비들과 동일하게 PSM 대상에 포함된다. 또한 소량의 가스 누출 시 인터록에 의해 가스가 차단되는 설비임에도 불구하고 KS표준에 따라 이론상 최대누출률을 적용하여 폭발위험장소 및 범위를 계산하도록 되어있다. 따라서 이 연구에서는 KS 표준에 따라 누출특성을 산출하고 CFD 시뮬레이션을 바탕으로 비교 평가하여 현재 CVD Gas Box에 대한 KS 표준을 적용함에 있어 폭발위험장소 설정에 대한 타당성을 검증하였다. 대상 물질은 디클로로실란과 암모니아로 선정하였으며, 환기 속도는 0.05m/s와 0.5m/s 기준으로 분석하였다. 환기속도가 0.05 m/s인 경우 KS 표준에 의하여 저희석으로 판정되어 방폭지역으로 설정되며, 0.5 m/s일 경우 고희석으로 비위험장소로 구분된다. 두 대상 물질과 두 조건의 환기속도를 적용하여 임계농도(LEL의 25%)까지 도달하는데 필요한 시간을 KS에 따른 계산과 CFD 시뮬레이션 계산값을 분석하였다. 분석 결과, 두 가지 물질 모두 KS 표준에 따라 계산된 임계농도에 도달하는 시간이 CFD 시뮬레이션으로 계산된 시간보다 보수적인 것을 확인하였다. 또한 고희석 조건인 0.5 m/s의 KS 표준 계산값이 저희석 조건인 0.05 m/s의 CFD 시뮬레이션 계산값보다 더 크다. 또한 Gas Box 내 가스가 누출될 경우 상시 배기시스템에 의해 능동적 배기가 되고, 인터록 시스템을 통해 1-2초 내에 인터록이 작동하여 차단된다. 따라서 CFD 시뮬레이션을 통해 계산된 임계농도에 도달하는 시간은 디클로로실란의 경우 15.2초, 암모니아의 경우 15.7초로 해당 시간 동안 가스가 잔류할 가능성이 없다. 그러므로 Gas Box 내 폭발 분위기 형성이 희박하다고 판단할 수 있으며, 이에 따라 CVD Gas Box는 CFD 시뮬레이션 결과를 바탕으로 비위험장소에 해당한다고 볼 수 있다. 이 연구는 가스 누출 방향을 한 방향으로 가정하여 진행하였다. 따라서 보수적인 누출 방향을 탐색하고 CFD 시뮬레이션 결과를 활용한다면 폭발위험장소 설정 시 경제적이고 합리적으로 적용할 수 있을 것으로 기대된다.

韓國의 輸出決定要因에 대한 硏究

박광수 崇田大學校 大學院 1985 국내석사

The Korean eonomy has achieved a stead and high growth since 1960's. Export has made a great contribution to the economic growth of Korea and will do so in the future. The purpose of this thesis is to analyze empirically what kind of factors influenced the export which has played a role as the engine of growth in the Korean economy. First, I examined four articles on the existing export functions in detail. Second, I explained the determinants of export, based on the demand and supply theory. Third, I specified exprot demand and supply equations and then estimated those equations by the ordinary least squares (OLS) method for 1973 1/4-1983 4/4. As a result of the estimation, I suspect that there has been the export promotion policy which could not be calculated statistically. This is the same result as shown by Dr. Song's and Dr. Suh's studies. And the results of the estimation suggest indirectly that there must be the policy scheme which compensated exporters domestically for the loss that occurred by exporting goods at lower prices. But that policy has affected the balance of payments unfavorably. Thus, for the improvement of the balance of paymentsl export must be increased not by the fall in the prices of export goods but by intensifying price and non-price competitive activities through technical innovation. Of course, the export equations which are specified in this thesis are only stepping stones to further studies in this area. Therefore, I think that the efforts of modeling more proper export function will have to be continued.

돈사폐수의 BMP 향상을 위한 고도산화처리 연구

박광수 경북대학교 대학원 2014 국내박사

As a main source of pollution affecting the water quality of rivers or lakes, livestock wastewater accounts for only about 1% out of all the wastewater, but its pollutions load based on BOD is as much as 14% out of all the pollution load, compared to industrial wastewater or domestic sewage. Besides, since livestock wastewater has high concentrations of nitrogen and phosphorus as well as a high organic concentration, it brings about quite serious problems in terms of pollution load. Especially, the domestic amount of piggery wastewater is gradually increasing every year, but due to the prohibition of its ocean disposal, it is more urgent to devise an alternative method of disposing piggery wastewater. As a kind of high-concentration organic wastewater, piggery wastewater is mainly treated through an anaerobic process, and widely used to reduce sludges and produce methane. Besides, as the advanced oxidation process of piggery wastewater improves the treatment speed by increasing hydrolysis, which is the rate-controlling step of anaerobic process. Thus, this study treated piggery wastewater, flowing into the livestock wastewater disposal plant, through various advanced oxidation process methods, and evaluated the livestock wastewater disposal plant, through various advanced oxidation process methods, and evaluated the characteristics of methane generation through a BMP(Biochemical Methane Potential) test and a batch experiment. To compare the solubilization of piggery wastewater, this study investigated the solubilization characteristics of piggery wastewater created through such individual treatments as Fenton oxidation treatment, alkali treatment, heat treatment and microwave treatment, ultrasonic treatment and ozone treatment, and such alkali-combined treatments as alkali-heat combined treatment, alkali-microwave combined treatment, alkali-ultrasonic combined treatment and alkali-ozone combined treatment. Piggery wastewater is high in the contents of particulate organic matters, such as cellulose, hemicellulose and lignin, since its main components are from undigested feed ingredients, and due to highly-concentrated NH4+ and toxic substances from antibiotics, the biological treatment of piggery wastewater is hindered, and its HRT is long for anaerobic digestion. To solve such problems, such an advanced oxidation process is not only to increase the amount of methane gas by improving the solubilization efficiency and biodegradability of piggery wastewater, but makes it possible to use piggery wastewater as an external carbon source when connected to other follow-up processes. When piggery wastewater was treated through individual treatments, its solubilization rate was highest in the ultrasonic treatment with 52.90 % and 0.58 gSCODprod./gVSfed. and when treated through alkali-combined treatments, it was highest in the alkali-ultrasound combined treatment with 58.40 % and 0.64 gSCODprod./gVSfed. and in general, the solubilization rate was higher in alkali-combined treatments than individual treatments. In the BMP test, the accumulated amount of methane gas was most in the alkali-ultrasonic combined treatment (20KHz 60min), followed by the alkali-microwave combined treatment (900W 9min), and methane was generated 112.97 % and 92.43 % more than the control group respectively. Even in the BMP test, more methane was generated in alkali-combined treatments than individual treatments, and as a result of the BMP test, the treatments with higher solubilization rates showed a higher efficiency of methane generation. As a result of the BMP test, since the energy purely generated from piggery wastewater treated through the alkali-ultrasonic combined treatment was 11 % more than that of an anaerobic process with non-treated piggery wastewater applied, this method is expected to increase the economic efficiency. Especially, when combining the alkali treatment, whose cost for chemicals is low, with a treatment requiring a high expense for electricity like the ultrasonic treatment, it is possible to reduce the cost of electricity used for expensive ultrasonic waves and improve the proficiency of treatment, and it has a high possibility of commercialization. Besides, when organic waste resources are converted into energy through this method for the production of bio-gas, it is expected to contribute to supplementing a considerable portion of the energy consumption. Based on the results above, this study found out that the solubilization rate and biodegradability of piggery wastewater can be improved through the alkali-ultrasonic combined treatment, further leading to increasing the productive efficiency of bio-gas, reducing the hydraulic retention time in a follow-up anaerobic process and expenses used to heat up anaerobic digesters and even the amount of sludge generated. As a result, it is anticipated that we can have economic benefits by securing an alternative energy and reducing expenses spent on disposing sludge.

『팔상명 녹』의 系統과 文學的 實相

박광수 忠南大學校 1997 국내박사

Pal-sang-myung-hang-nok,(『팔상명□녹』) a biography which described the Buddha's achievements, is a representative work of Korean narrative of Buddhism at the late of the Lee Dynasty and an overall work of Buddhist literature with Buddhist literature of India and China. This book originates in Buddhist literature of India and China. inherits the Buddhist tradition of Wol-in-chun-kang-ji-gok.(『月印千江之曲』) Suk-bo-sang-chul,(《釋譜詳節》) and Wol-in-suk-bo.(《月印釋譜》) which are works about Buddhism in Korean at the beginnings of the Lee Dynasty. and supplements the Buddhist biography of the former days and is a biography which described completely the Buddha's life. 1. Buddhist literature orignated in India, spread to China, and was fundamentally in accordance with literary form. Buddhist literature of India has been handed down orally by traditional ways. And it is said that the contents of Jataka in Bharhut, Sanchi's Buddhism remains regard as relief. Buddhist literature was collected and supplemented with memoirs in the Buddhist literature collection and at, about 2 century, when Buddhacarita was written by A□vagho□a(馬鳴), was formed perfectly into Buddhist literature. Buddhist literature of China was classified roughly into Sanskrit-Chinese translation and new compilation. Since Buddhism has handed down, highly-developed Sanskrit Buddhist literature with Yok-kyung.(譯經) which is called literature in translation. generally holds a position of Sanskrit-Chineses translation. A kind of the sutra such as Chun-bob-yun-kyung (《轉法輪經》) and Yol-ban-kyung.(《涅槃經》) and the Buddhist scriptures. a kind of Buddha's biography such as 「Lalitavistara」 . 「Buddhacarita」. 「Mahavasta」 and Buddha's biography, a kind of discipline were introduced. There are Suk-ka-bo. (《釋迦譜》) Suk-ka-si-bo. (《釋迦氏譜》) and Suk-ka-yo-rae-sung-do-ki (《釋迦如來成道記》) as new compilation in Buddhist literature. 2. Buddhist literature of Korea came from that of India and China, and was very popular with the Buddhist and the masses as the centeral figure with two-sided of Buddhist literature and narrative. Suk-ka-yo-rae-sip-ji-soo-hang-ki(《釋迦如來十地修行記》and Suk-ka-yo-rae-hang-juk-song(「釋迦如來行蹟頌」) of Koryo and Wol-ia-chun-kang-ji-gok. (「月印天江之曲」) Suk-bo-sang-chul, and Wol-in-suk-bo. which are written at the beginnings of the Lee Dynasty, are representative works. At the late of the Lee Dynasty it supplemented a short story and made the Buddha's biography in association with Korean novel which was much in fashion in those days. 3. Pal-sang-myuzg-hang-nok. on the whole. is consisted of the eight laksana(相) structure. The eight laksana is based on the Buddha's achievements and divided into eight. And each laksana is composed of a short story and takes narrative form. This eight laksana has respectably various matter with a short story form and shows a descriptive aspect. While Pal-sang-myung-hang-nok, on the whole. has completely narrative structure as a biography, a short story also has a consistent narrative structure. Therefore, among the short stories, Sun-kwang-kong-jo-chun(「선광공주전」) and A-ran-kyul-yuz-ki(「아란결연기」) are prescribed to a kind of short story: Mok-ryun-chun(「목련전」) and Ya-soo-bin-chun.(「야수빈전」) a kind of a short novel: Sun-woo-tae-ja-chun(「선우태자전」) and Jang-ja-boo-in-chun.(「장자부인전」) a long novel: and their's aspects are researched. Pal-sang-myung-hang-nok uses only Korean instead of Korean together with Chinese in style. And it takes the style of old novel in characterization, setting, and development of story. Pal-sang-myung-hang-nok, the Buddha's biography. includes the various genre in the formation and the development of Korean narrative. A short story assumes the form of a short novel. as a whole the form of a saga novel and a serial story. and gives an aspect of novel. And it was also performed by the biblical drama and assumed an aspect of the play or drama of Buddhism. 4. Pal-sang-myung-hang-nok led the formation of Korean narrative at the late the Lee Dynasty and made colorfully the history of' literature of the late of the Lee Dynasty. This book has to be estimated afresh and has significance of study in that Korean novel's aspect and the novel history can be understand easily because it seems to be in ?he stream of the history of Korean narrative.

In the part of artistic style so called A painting in the literary artist´s style is depending on neither outer part of figure nor appearance but inner part of spirituality and expressing author's will. Therefore, object does not in a concrete presentation, it is focus on its symbolismand simple painting and enough margin in a canvas can be increased its quality. Woobong Cho, Hee Ryong is a well known writer as well as a painter in a late Chosen period.. He, who himself is in a merchant class, was good at literary work but he shows his best ability in literary painting. Moreover, he is a follower of Choosa- Kim Jung Hee who is great man in a painting and writing field. Furthermore, he was involved in Yeehang literary men's club which is regular meeting for merchant class artists. He believes Master Kim's representation which is including its Spirituality and Symbolism more, give more potential on importance of technique occur higher the great values. Woobong's idea has contributed much to future studies of artistic value on the painting in the literary artists style In that sense, Woobong's painting circle could took a role from the gentry's coercive art to using his brush like free as a wind, openly using his ability to express himself causes his own world in literary field as well that is why It maintain this thesis.

Novel quercetin conjugates : synthesis, pharmacokinetic properties, and biological activities

박광수 건국대학교 대학원 2010 국내석사

Low bioavailability of quercetin has been tackled by conjugation with various promoieties. In this study, novel quercein conjugates with pivaloxymethyl (POM) promoieties attached at non-catecholic 7-O and/or 3-O position [7-O-POM-Q (2), 3-O-POM-Q (3), 3,7-bis-O-POM-Q (4)] were prepared, which, depending upon the position where the POM promoiety is introduced, showed characteristic physicochemical as well as biological properties. HPLC analysis of the cell lysates as well as fluorescence staining of the intracellular quercetin and its conjugates confirmed that a POM group attached on 7-O position enhanced cellular uptake of the corresponding conjugate (2) followed by sustained intracellular release of quercetin whereas 3-O-POM promoiety provided 3 with low intracellular localization and high stability. The characteristic physicochemical properties of the POM promoieties at 7-O and 3-O positions were combined in 4 to result in accumulation of the conjugate inside the cell followed by selective hydrolysis to 3. Cell viability assay and cell cycle distribution analysis showed that cellular uptake followed by hydrolysis into quercetin and 3-O-POM is responsible for the observed cytostatic effects as well as cell cycle modulation activities of the conjugates 2 and 4, respectively. Taken together, through positional scanning of a POM promoiety on non-catecholic hydroxyl groups of quercetin, we demonstrated that conjugation of naturally occurring flavonol with a POM promoiety at non-catecholic hydroxyl groups can enhance stability and intracellular accumulation of the corresponding quercetin conjugate to result in sustained release of the active ingredients inside the cell.
