김장식 부산교육대학교 교육대학원 2000 국내석사

개별화와 다양화가 요구하는 최근의 학교 교육 현장에서는 기존의 획일적인 학교시설·설비로는 대응하기 어려운 매우 다양한 형태의 학습공간을 요구로 인하여 교육시설·설비 기준이 바뀌었다. 본 연구는 실과 교육에 있어서도 이러한 변화에 대응하기 위해 초등학교 실과 교육 관련 시설·설비의 활용실태를 조사하고 이를 바탕으로 향후 실과 교육 시설의 적극적인 활용을 위해 실과 실습실에 오픈시스템을 적용할 수 있는 시설·설비 모형과 효율적인 운영 방안을 제시함으로써 초등 실과 교육을 위한 바람직한 실과 실습실의 모델을 제시하는데 있다. 이러한 목적을 달성하기 위하여 질문지에 의하여 실과 교구 종목별 최소 소요 기준에 준거하여 실과 교구가 적정하게 보유되고 있는지를 조사 분석하였고, 초등학교 3, 4, 5, 6학년 실과 교과의 영역별로 각 1차시씩 총22차시의 단원을 선정하여 실과실습실의 유무에 따라 교구의 활용율을 비교 분석하였다. 이러한 연구 결과는 다음과 같다. 첫째, 실과 교구 기준안에 근거한 교구 보유 현황 분석에서 조사 대상 학교의 평균 교구 보유율은 25.2%로 나타났으며, 이는 초등학교에서 실과 교구 부족으로 실과실습을 효율적으로 수행할 수 없음을 의미한다. 둘째, 조사대상 42학교 중에서 40%만 실과 실습실을 보유하고 있었다. 따라서 초등학교의 실과 실습실과 실과 교구 보유실태는 매우 낮았으며, 그렇기 때문에 실과 교과의 효율적인 학습과 교사의 적극적인 실습을 돕기 위해서는 다양한 공간을 갖춘 실과 실습실의 설계가 필요하다고 판단되어 오픈시스템 적용을 위한 실과 실습실의 시설·설비의 운영방안을 제시하게 되었다. 오픈 시스템 적용을 위한 실과 실습실 시설·설비의 설계와 운영방안은 다음과 같다. 첫째, 실과 실습실을 主活動空間, 栽培空間, 情報交換空間의 3개 領域空間으로 설계하였다. 主活動空間에는 실습대와 개수대의 규격을 초등학생의 신체 조건에 맞게 설계하여 배치하고, 실습대마다 전기시설을 갖추어 설계·공작, 전기·전자, 조리 영역의 실습을 하도록 하였다. 栽培空間에는 실외공간에서 실습하기가 어려운 경우의 가꾸기 영역 실습을, 情報交換空間에는 다양한 교수·학습 활동을 수행함에 있어 학습지원공간으로서 인터넷이나 조사학습 등 실과 교과 학습에서 다양한 자료를 제공하는 공간으로 운영하게 하였다. 둘째, 실과 실습실의 운영방안으로는 주 활동 공간의 실습대를 자유롭게 이동할 수 있도록 하여, 실과 교과에서의 문제해결력을 신장시킬 수 있도록 하였다. 또 실습대의 자유로운 이동이 아동들의 창의적인 수업과 소집단 활동 등 다양한 형태의 수업에 도움이 될 수 있도록 하였다. 실습대 밑에는 재봉틀과 기타 공구를 넣을 수 있는 공간을 마련하여 편리성을 도모하였다. 따라서 오픈 시스템을 적용한 실과 실습실이 실과 교과의 모든 영역을 실습할 수 있고, 실습실 운영자에 따라 교사의 다양한 사고를 수용할 수 있는 공간 설계와 운영방안으로 교사와 학생들에게 많은 도움을 줄 것으로 기대된다. The purpose of this paper is to obtain data which will be applied for effective future practical arts education and practical arts laboratories based on the open-system. The obtained results are the following. First, out of 42 elementary schools that were surveyed, only 40%, that is 17 schools had equipment and facilities for practical arts education. Second, regarding the performing arts equipment standard, the survey results for the 42 schools' average equipment holding rate was 25.2% which show that effective practical arts education can not be done regarding the lack of equipment. Over all results show that the elementary schools have a low holding rate for equipment and facilities for practical education. Therefore there is a need for designing a practical arts laboratory which will aid the teacher for effective education. Design of an open-system model with 3 areas which are the main activity space, cultivating space and multimedia space is presented.

김장식 전남대학교 대학원 2003 국내석사

Mobile IP에서 IP층 핸드오프 중에 지연과 패킷 손실이 존재할 수 있으며, 이 중 지연은 실시간 서비스 또는 지연에 민감한 서비스에 크게 영향을 미친다. 이러한 지연을 해결하기 위해서 IETF에서는 링크계층 정보를 이용하여 사전등록과 사후등록을 할 수 있는 Low Latency Handoff를 제안하였다. 여기에서는 이전 외부에이전트와 새로운 외부에이전트가 존재하여야 되며, 만약 새로운 외부 에이전트가 존재하지 않는다면 기본 Mobile IP을 수행하게 된다. 그러나 다양한 네트워크환경에서 외부에이전트가 존재하지 않은 경우도 있을 수 있다. 본 논문에서는 이러한 상황에 적응하도록 링크계층 정보를 사용하여 사전등록과 사후등록을 할 수 있도록 제안한다. Latency and Packet loss may be present in Mobile IP during handoff. The Latency involved in these handoff give bed influence to real-time or delay-sensitive services. So IETF proposed Low Latency Handoff performing Pre-Registration and Post-Registration with Link Layer information. This proposal always require the present of old Foreign Agent (oFA) and new Foreign Agent (nFA). If new Foreign Agent is absent, Mobile IP perform basic Mobile IP Handoff, but the various network environment may do not have new Foreign Agent. To adapt to these situation, This paper propose new Pre-Registration and Post-Registration with using Link Layer information.

知的財産權의 濫用類型과 獨占規制法의 適用에 關한 硏究

김장식 延世大學校 法務大學院 2005 국내석사

Intellectual Property has several distinct characteristics comparing to other properties. They are as follows; First, the acquisition of it needs a lot of time, effort and cost investment. Second, the trespasser can easily intrude into its rights but it is not easy to be compensated. Last, it is kind of abstract property.Because of these characteristics of intellectual property, Intellectual Property Act gives exclusive and monopoly intellectual property rights to the owner, and it is squarely opposed to Antitrust Law which accomplishes efficient distribution of resources by the free competition between each competitive owners and the formal aspect of this Act. However, the common point of these Acts is that the purpose of these Acts is development of national economy and national industry. Hence coexistence of these Acts is possible without any conflicts.Though intellectual property rights have exclusive and monopoly rights for a certain period as a incentive by national political consideration, nobody can be assigned monopoly rights in the markets, and it is limited in right excercise by the potential restrictions such as registration revocation, mandatory enforcement, fair utilization and so on according to the positive laws such as the Patent Act, the Trademark Act and the Copyright Act and the legal principles of intellectual property misappropriation because it does not have any exception under our market economy.However, because application of Antitrust law for the excercise of intellectual property rights affect the concerned intellectual property rights greatly, it is necessary that the unfair excercise types of intellectual property rights and definite application standards for them respectively should be settled in order to promote consistency and foreseeing possibility in application of laws.Accordingly, Fair Trade Commission established 'Inspection Instruction for unfair excercise of intellectual property rights' in order that Anti - trust Law, whose application was limited to international contracts, could be applied to the excercise and trade of intellectual property rights at home also. Therefore, it is expected that it is contribute greatly to the development of innovative technology, the growth of national industry and national economy. 흔히 脫産業社會(Post-Industrial Society), 情報化 社會(information society)라 불리는 21세기는 인간의 知的創作物에 의한 知識基盤産業이 이루어진다고 한다. 이에 따라 有形의 物質構造보다 無形의 知的創作物인 知的財産의 중요성이 한층 강조되고 있는데, 이러한 知的財産은 다른 財産과는 달리 몇 가지의 特徵이 있는데, 우선 그 取得에는 많은 시간과 노력 그리고 비용이 투자되어야 하는 것과 侵害者에 의한 權利의 侵害는 비교적 용이한 반면에 그 侵害에 대한 救濟는 용이하지 않다는 것, 그리고 다른 財産에 비하여 그 形體가 없는 것 등을 그 차이점으로 들 수 있다. 知的財産權法은 이러한 特徵을 가진 知的財産權을 보호하기 위하여 知的財産權者에게 排他的이고 獨占的인 權利를 부여하고 있다. 그런데 知的財産權者에게 부여된 排他的이고 獨占的인 權利는 競爭事業者들 상호간의 自由競爭을 통하여서 효율적인 자원의 배분을 달성하려는 「獨占規制 및 公正去來에 관한 法律(이하 ‘獨占規制法’이라 한다)」의 理念과 法의 형식적인 측면에서 서로 상충된다. 여기에서 知的財産權法과 獨占規制法의 갈등이 생긴다.그런데 국가의 정책적인 배려에 의한 인센티브(Incentive)로서 일정기간 排他的이고 獨占的인 權利가 知的財産權者에게 부여되어 있다고 하여도 知的財産權 그 자체로서는 시장에서의 獨占을 형성하는 것이 아니며, 또한 우리의 市場經濟秩序下에서 公正한 競爭秩序에서의 예외도 될 수 없는 것이다. 따라서 知的財産權도 特許法 商標法 著作權法 등의 實定法에 의한 登錄取消 强制實施 公正利用 등의 내재적인 제한과 知的財産權 濫用의 法理에 따른 權利行使의 制限을 받게 되므로 知的財産權에 인정되는 배타적인 獨占權은 무제한적인 獨占權으로 인정되는 것은 아니라고 할 것이다.이와 같이 知的財産權法과 獨占規制法은 비록 法의 존재형식에서는 서로 대립하고 있는 것처럼 보이나 國民經濟와 消費者厚生, 國家産業의 發展이라는 공통의 목적을 추구하고 있음을 알 수 있다. 여기에 서로 상충되는 것처럼 보이는 兩 法域이 모순 없이 조화롭게 공존할 수 있는 여지가 있다고 할 것이다. 따라서 이러한 兩 法의 目的을 최대한 반영하여 不當한 知的財産權의 行使에 대하여는 知的財産權法 자체에 내재하는 제한이나 獨占規制法의 適用으로 시장에서 과다하게 競爭을 저해하는 요인을 제거하면서도 知的財産權의 保護도 동시에 이룰 수 있는 兩法의 조화로운 운용이 필요하다고 할 것이다.그런데 知的財産權의 行使에 대한 獨占規制法의 適用은 당해 知的財産權者의 權利에 상당한 영향을 미치게 되므로, 法의 適用에 있어서 一貫性과 豫測可能性 더 나아가 市場에서의 公正한 去來慣行의 형성을 촉진하기 위하여 不當한 知的財産權의 行使類型과 이에 대한 獨占規制法의 適用에 있어서 명확한 適用基準을 확립할 필요성 있다.한편 우리 公正去來委員會는 「知的財産權의 不當한 行使에 대한 審査指針」을 制定(2000. 8. 30.)하여 獨占規制法이 국내에서의 知的財産權의 行使 내지 去來에 대하여도 適用이 가능하도록 하고 있는데, 그 적용에 있어 혁신기술의 개발 및 국가산업의 발전과 國民經濟에 도움이 되는 公正하고 조화로운 法의 運用이 되었으면 한다.

This study has analyze the Reading section text of TOPIK from 11th to 21st using by Dale-Chall Method, one of the typical Readability formula and search the difficulty of each grades and tests by the readability index calculated. Words, sentences and difficulty of the words in texts are the point of the readability analysis among several factors . This study is looking at various formulas based on Korean and English, especially focusing on the Dale-Chall formula, authorized as one of most accurate, and reformulating a criterion of formula measurement for text analysis of TOPIK, and drawing up a word list for each ratings. It has analyzed 852 of texts - 300 of elementary level, 288 of intermediate level, 264 of higher level - from 12 of tests and calculated the readability index. Based on the readability index, it has searched the feature of each test and high, medium, low ratio in difficulty level of each grade and graded change of index for each test. Words and sentences which were used for texts and the number of difficult words were examined in relation to features of readability. As a result, the following problems were found. In other words, the degree of difficulty in accordance with the upper/middle/lower grade was not well distributed. While the degree for the elementary grade was excessively low on the whole, it was so high for the advanced grade. Moreover, the number of difficult words had an effect on the degree in the intermediate and advanced grade, where the number of words and sentences was relatively regular. Accordingly, as reform measures, this study suggested that the degree of difficulty be controlled through appropriate distribution and use of difficult words for upward adjustment of the degree of difficulty in the elementary grade and maintenance of its uniformity.

This study is intended to improve curriculum of the Korean education department of INAES in Paraguay based on the environmental analysis to be preceded for curriculum development. The factors for environmental analysis in the established language curriculum are not suitable as the ones to be analyzed for development of the overseas Korean education department curriculum aimed at fostering Korean language teachers. Accordingly, the factors for environmental analysis to be analyzed when cultivating Korean language teachers were set up to be applied to the improvement in curriculum after an in-depth analysis. To be concrete, the present conditions of the Korean education department of INAES and its curriculum were analyzed according to the factors for environmental analysis and problems were drawn. After then, a requirement analysis targeting the learners and teachers was conducted, and the results were analyzed to present a curriculum development plan reflecting this. The content of this study summarized by chapter is as follows. Chapter 1 identified the necessity and purpose of this study and examined the significance of the study on Korean language curriculum as the base of discussion. Precedent studies on overseas development of Korean language curriculum and Korean language curriculum were examined as well. It was found that the content of studies on the existing overseas development of Korean language curriculum was limited to the current status without a specific set-up of the factors for environmental analysis. In Chapter 2, the theoretical background of the type and procedure of curriculum was considered as the basis for discussion on curriculum improvement, and the discussion on the environmental analysis with regard to the development of curriculum was reviewed. In addition, factors for the environmental analysis necessary for the curriculum to cultivate Korean language teachers were established. Chapter 3 analyzed the environment of the Korean education department of INAES in Paraguay by factor with the environmental analysis factors established in Chapter 2. The curriculum of the department currently in progress was examined in detail, and the local policies for foreign language education and cultivation of foreign language teachers, and the status of Korean language in the country were analyzed as dividing the environments internally and externally. In Chapter 4, the needs of the learners and teachers to improve the curriculum of the Korean education department of INAES were investigated, and the analysis results were presented. The questionnaire participants were 56 learners and 12 professors. Additionally, a total of 54 learners and professors responded to a questionnaire about the necessity of subjects required to acquire the second Korean language teacher's license. The teachers were limited to those who teach Korean in the country or have experience in teaching the language. The questions were largely divided into general items and research on the curriculum improvement. The research on perception on Korean language showed that there was a difference between the Spanish-speaking learners’ perception on Korean language and their perception on other languages. In addition, it was identified that their responses regarding Korean language classes, circumstances, topics, and learning objectives demonstrated that the learners, the teachers, and the educational environment in Paraguay currently required a new curriculum. The results drawn from this were fed and applied into the development of curriculum in Chapter 5. Based on the earlier studies, a plan for improvement in the curriculum was presented in Chapter 5. Specific content was proposed focusing on education objective, selection of educational content, arrangement of educational content, and outline of subjects. It was set with the purpose of nurturing professional Korean language teachers with expertise in the language and abilities to have as a language teacher, with the principle of curriculum design as a comprehensive technique, versatility, practicality, and clarity. Next, the purpose and objective of the Korean education department of IANES were concretely established, and the subjects were selected based on non-native Korean language teachers’ competences and INAES curriculum. This study precisely informed the current status of Korean language education in Paraguay in Latin America, which had not dealt with in previous studies, analyzed the Korean language curriculum in this Spanish-speaking country and figured out its problems, and established the environmental analysis factors that had not been closely considered in the existing overseas departments to cultivate Korean language teachers. This will serve as a standard for the development of curriculum for training overseas Korean language teachers. It has a significance in that it designed a curriculum to cultivate Korean language teachers with a focus on improving non-native Korean language teachers’ competences and applied it to the actual overseas Korean education department curriculum.

계통연계형 PWM 컨버터에서 LCL필터의 필름 커패시터 수명 추정

김장식 부산대학교 2012 국내석사

A capacitor deterioration of LCL-filter grid-connected PWM converter is progressed by the self-healing mechanism. It leads to degradation of the filter performance and drop of power factor. Thus, it is required to diagnose fault-point of capacitor and determine replacement time. Typically, the fault of capacitor is determined when the capacitance is reduced up to 80% from initial value. This paper proposes algorithm in order to determine capacitor replacement time of LCL filter. The algorithm takes advantage of changes of response on injected resonant frequency corresponding 80% value from initial capacitance. The results of the algorithm are demonstrated through simulations and experiments.

In modern mobile communication, the communication equipment is constrained of small size, light weight, low cost and case of compact type. Especially in wireless LAN system, these demands of user has increased to provide for useful mobile communication. Therefore, the microstrip patch antenna is a very suitable element to these purpose. In this study, a microstrip patch antenna which apply to 5.5 [GHz] RF module is designed and fabricated for local wireless LAN system. At first, on the basic principles of antenna and designing has reviewed, then a initial single patch has calculated with the equations for 5.5 [GHz]. It is optimized to set the rectangular patch with lower input impedance using EM simulator and then designed the 1x2 microstrip patch array antenna to obtain a higher gain and omni-directional. The second, we have designed a quarter wave impedance transformer and T-Junction power divlders to feed each radiation element. At simulation of the single patch antenna, we has obtained the return loss of -28 [dB], gain of 5 [dBi] in resonant frequency of 5.5 [GHz], And then the 1×2 array patch antenna is resulted the return loss of -33 [dB], gain of 8 [dBi], radiation of ernni-directional and input impedance of 47.8+j0[Ω] The single patch antenna and 1×2 array patch antenna were fabricated on the substrate using RF-35 of Taconic company that is based the simulation results. The measurement of prototype antenna has used the Anritsu 37169A vector network analyzer. At the result of measurement, we has obtained the superiority peculiar character, which is the return loss of -32 [dB], input impedance of 48+j1 [Ω], VSWR of 1.132 In frequency band of 5.5 [GHz] using the prototype of 1x2 array patch antenna.
