The aims of the project of Dongbuk is to research that the history of Manchuria has not relationship with korean history but has much relationship with chinese history. Therefore the researchers of China proper who have taken pan in the projects of Dongbuk proclaimed that Balhae and Koguryo had much relationship not to Korea but to China. The most important problem on the Balhae history is that it was belong to korean history and succeeded the kingdom of Koguryo has been attacked by them furiously. Looking into their papers on them, I have found that their target is to denied the Yu Duk Gong's theory. So thus I have studied and arranged all about Nambukguk theory from it's origin to it's conclusion, the Nambukguk times theory. And after this, I arranged the principals and paradigms of the Nambukguk times theory. Nambukguk theory had been expressed in the preface of the Balhaego written by Yu Duk Gong(l748-1807). In this, he had asserted that 3 kingdoms age succeeded by Nambukguk which was consisted by the enlarged Silla in the southern part and the kingdom of Balhae which succeded the kingdom of Koguryo in the northern part. Of course, I think that Yu had no notion of the historical word, times. But his notion of Nambukguk had given strong impact to Han Chi Yun, Chung Yak Yong, Hong Suk Joo, Kim Jung Ho and Sin chae Ho. So they had adopted Yu's idea and had studied the history of Balhae kingdom. In the imperial Japan colonial times, the korean people encountered the crisis to be perished away. So they studied their ancient history focusing at the spirit of nation and reached to the Nambukguk times theory. I can introduce the scholars. They are Jang Do Bin, Son Jin Tae, and so on. After liberating from imperial Japan, Pak Si Hyung and Yi Woo Sung presented the very same idea of Yu Duk Gong. Otherwise, in the past the respecters of China proper studied the history of Manchuria what they occupied in order to obtain historical evidences about it. in the first step they encountered one of the most important thing that where Balhae history belongs to. But at last they founded that there is no clue that Balhae history belonged to chinese history, and became to know the existence of Nambukguk theory in Korea. So they showed their nervous attitude and attacked Yu and Yu's work, Balhaego They are Sun Wei Ryang, WangJin Kun and Sun Jin Ji. In these years, Quo S00 Mei, Woo Wei Hwan, Wang Cung Quo, Chang Bee Puo and Chao Hong who took part in the project of Dongbuk argued that the history of Balhae belongs to chinese history without reason. Reading their papers on this carefully, I find out that they perhaps wrote the papers following some directions which ordered by someone. So the papers of their look like same one written by one people. Conclusionally speaking, I can declare that they commit following 3 points that were very important and became the basic conditions to study ancient history. 1. They selected and analyzed historical matters in such a very simple way. 2. They misunderstand the ancient history by their wrong view of the world, so called Cheonhagwan. 3. They have no notion of the change in community in ancient society. In these 3 facts, I determined that they who took part in the project of Dongbuk had made no development in studying Balhae history. They only followed the bad points of the principals of the historical view, Manseon historical view in imperial Japan times.

This study was performed to define the cytotoxicity and the anti-inflammatory action of Pulsatilla koreana extracts. To analyze cytotoxic effects, gingival and periodontal ligament fibroblasts were used, and anti-inflammatory actions related to reduction of $IL-1{\beta}$ and $PGE_2$ production were performed in vitro, for the suggestion of efficacy and safety on periodontal therapeutic use of Pulsatilla koreana extracts. We extracted ethylacetate and butylalcohol from well-dried and ground Pulsatilla koreana throughout multiple processing, then used different concentration solution(0.1 %, 0.2 %, 0.4 %, 0.01 %, 0.02 %, 0.04 %, 1 %, 2 %) of ethylacetate and butylalcohol extracts to examine eytotoxic effects and anti-inflammatory actions Cytotoxic effects were examined by ELISA reader using MTT(Methyl Thiazol-2-YL-2, 5-diphenyl Tetrazolium bromide)solution following culture of human gingival and periodontal ligament fibroblasts. Synthesis of $IL-1{\beta}$was examined by $IL-1{\beta}$ enzyme-immunoassay(EIA)system after separation and culture of monocyte, and $PGE_2$ was examined by $PGE_2EIA$ system after culture of gingival fibroblasts. The results were as follows: 1. In the MTT test of gingival fibroblasts, the change of optical density was decreased significantly at 2 % of butylalcohol extracts and 0.04 %, 0.1 %, 0.2 %, 0.4 %, 1 %, 2 % of ethylacetate extracts.(p<0.05) 2. In the MTT test of periodontal ligament cells, the change of optical density were not differ significantly. but butylalcohol and ethylacetate extracts except from butylalcohol 0.01 % showed high cell cytotoxity. 3. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of $IL-1{\beta}$and inhibition effect of ethylacetate extracts were higher than butylalcohol extracts. 4. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of $PGE_2$, and ethylacetate extracts were higher than butylalcohol extracts. In conclusion, ethylacetate and butylalcohol extracts from Pulsatilla koreana showed little cell cytotoxity for gingival and periodontal ligament fibroblasts, and the inhibition of $IL-1{\beta}$ and $PGE_2$ sysnthesis, therefore it is considered that these extracts can be developed as the therapeutics of the periodontal disease.

Recently, the study of cities of culture is not only an issue of relevant scientific, but also an extremely current topic in urban development. In Korea, many cities are trying to apply cultural approach for upgrading city quality and increasing city``s competitiveness. However, due to the broad definition of culture, so many different development policies have been introduced in many Korean cities. This paper examined the importance of key issues raised in development process of cultural city using the AHP method, in Incheon metropolitan city. Survey techniques were used to gather the data about the importance of key issues in realizing the city of culture, for both professional and citizen groups. Research results show that for cultural planning of city, development goal or objective must be clearly established, and recommend to contribute to set the city identification and enlarge the regional diversity with enforcement of the neighborhood activities for local citizen.

The purpose of this study is to design a rehabilitation center for the acquired visually impaired individuals. Currently there are facilities related visual impairment such as a school for the blind and welfare center and there, limited educational and vocational rehabilitation training are performed. However the blinds recognize space based on the surrounding sensory experiences by repetition, existing facilities didn"t consider sensory elements in architectural design. Therefore this study aims to evoke senses which weren"t able to recognize before and save psychological sense of loss after visual impairment. And design proposal can be provided repetitive experiences for the visually impaired individuals by forming circular space according their walking principal.

한계가치의 상관성과 호혜주의적 담합하에서 최적 계약 결정에 관한 연구

정진한 ( Jin Han Jung ) 한국산업조직학회 2010 産業組織硏究 Vol.18 No.4

본 연구는 (i) 대리인간 호혜주의적인 담합 가능성이 존재하고 (ii) 공공재에 대한 한계가치가 양의 상관관계를 가지는 동태적 주인-대리인 모형에서 상관관계가 최적계약결정에 미치는 영향을 분석한다. 우선 대리인간 계약에 따른 담합이 가능한 기본 모형 분석을 통해, 높은 상관관계가 담합비용을 증가시키고 균형에서의 계약이 부분적으로 공공재의 한계가치들 반영하지 않음을 나타내었다. 그러나 동태적 모형 분석에서는 높은 상관관계가 대리인들의 다기간 담합에 따른 기대수익을 감소시킴으로써 호혜주의적 담합유인 을 보다 약화시킬 수 있음을 보여주고 있다, 따라서 균형에서의 최적 계약은 이러한 다기간 인센티브와 기간별 인센티브간의 상충적 상호작용에 의해 결정됨에 따라, 높은 상관관계에 있는 경우에도 최적 계약이 대리인들의 한계 가치에 따라 결정되는 보다 효율적인 결과를 낳을 수 있음을 보여주고 있다. 또한 높은 양의 상관관계가 담합에 따른 동태적 거래비용을 감소시켜 효율성을 개선할 수 있음을 분석하였다. This paper studies optimal collusion-proof contracts in a dynamic model where (i) agents are willing to collude with each other by reciprocal behavior and (ii) valuations for public goods are positively correlated. As a benchmark case where collusion is enforceable with side-contracts between agents, strong correlation makes collusion deterrence more costly and entails partially-pooled output schedules. In the dynamic structure, however, the degree of correlation may reduce the continuation gain from on-going collusion since the possibility of collusion diminishes. Accordingly, whether optimal outputs are partial-pooling or not depends on the conflicting interaction between the intertemporal incentive and the per-period incentives under self-enforcing collusion. As a result, the government can screen agents` valuations even with strong correlation by taking advantage of the conflicting incentives. In addition, strong correlation makes the convergence to the worst outcomes slow by mitigating the collusion incentives over time.

정진효(Jin-Hyo Jung),양원혁(Wonhyuk Yang),김영천(Young-Chon Kim) 한국통신학회 2013 韓國通信學會論文誌 Vol.38 No.2B

최근 풍력 발전 단지가 대형화 해상화됨에 따라 이를 모니터링하고 제어하기 위한 통신망의 중요성이 높아지고 있다. 본 논문에서는 해상 풍력 단지에서 사용하는 기존 Ethernet 기반의 통신망의 문제점인 지연시간, 데이터 처리 오버헤드 및 풍력 발전기간 데이터 전송의 공평성 문제를 해결하기 위하여 EPON(Ethernet Passive Optical Network) 기반의 통신망 구조를 제안하고 성능 평가를 수행한다. 제안한 구조는 OLT(Optical Line Terminal)를 중앙 제어 센터에 설치하고 해상의 풍력 발전기에 ONU(Optical Network Unit)를 설치하여 점 대 다점 통신망을 구성하는 토폴로지이다. EPON 기반 토폴로지는 수동소자를 사용함으로써 망 구성 비용이 저렴하고 관리가 용이하며 높은 신뢰성과 데이터 전송의 공평성을 보장할 수 있다. 제안한 통신망 구조의 성능을 평가하기 위하여 OPNET Modeler를 이용하여 IEC 61850 표준을 기반으로 한 풍력단지를 모델링한다. 시뮬레이션 결과는 기존 이더넷 기반의 통신망과 지연시간, 오버헤드 및 전송의 공평성 관점에서 비교 분석한다. In recent, the communication networks of wind power farm are becoming crucial technologies for monitoring and controlling the large-scale offshore wind power farm. In this paper, EPON based communication network architectures are proposed in order to combat the problems of conventional Ethernet based communication network such as delay, data processing overhead and the fairness of data transmission among turbines in offshore wind power farm. The proposed architecture constructs the point to multi-point network by using OLT and ONUs installed in central control center and wind turbines respectively. The EPON based communication network architecture has low cost, high reliability, and fair transmission capability. To evaluate the performance of proposed architectures, the wind power farm based on IEC 61850 is modelled by using OPNET The simulation results are analyzed and compared with conventional Ethernet based communication network in terms of the overhead, delay and fairness of data transmission.

정진현(Jung, Jin Hyun) 한국실과교육학회 2007 한국실과교육학회지 Vol.20 No.3

The purpose of this study was to find the plan to improve the design education which was able to execute it systematically and practically in elementary practical arts. For achieving the purpose of this study, it inquired into the theory about elementary design education, analyzed the contents about design education shown in practical arts textbook, and investigated the current status about design education of practical arts in elementary schools. For analyzing the contents about design education, the contents were grouped into aestheticㆍsymbolic expression area, usefulㆍfunctional performance area, scientificㆍtechnological application area, and socialㆍemotional attitude area. For the questionnaire in elementary schools, subjects are 165 charge teachers of the 5th and 6th grade in Daegu. The method of this survey has been through the arbitrary-chosen questionnaire. Results of this study were as follows: 1. Contents about design education in practical arts textbook focus more on estheticㆍ symbolic expression area and usefulㆍfunctional performance area than other areas. Scientificㆍtechnological application area have smaller proportion in practical arts. Therefore, contents about scientificㆍtechnological application area are necessary to put into practical arts textbook more and more. 2. It is necessary to supplement for the working process because teachers cannot enough to understand about the working process of products, when they teach the making and decorating in class. 3. It is necessary to use the educational media positively, to develop the design materials for teaching the making and decorating. 4. Considering the creativity extension of students, it is necessary to improve following products of textbook alike. 5. For activating design education in practical arts, it has to equip with the facilities and tools for practical arts instruction, has to expand the charge teacher for practical arts gradually, has to study for improving the quality of practical arts teacher, and needs to develop the reference books for design education in practical arts.
