The business models has a great impact on the successful management of enterprises. Business environment has been shifting from industrial economy to knowledge-based economy. Enterprises go through numerous trials for successful management in the changing environment. Along with trial tests, research areas have been growing simultaneously. Although many researches have been conducted with regard to business models, it is very insufficient to systematically analyze the knowledge flow of research. Accordingly, successive researchers who want to study the business model may find it difficult to establish the orientation of future application research based on understanding the process of changing the knowledge structure that have accumulated so far. This study is intended to determine the current state of the business model research and to understand the process of knowledge structure changes in keywords that appear in 2,667 business model articles in the SCOPUS database. Identifying the knowledge structure has been completed through social network analysis, a methodology based on the 'relationship', and the changes in the knowledge structure were identified by classifying them into four different periods. The analysis showed that, first, the number of business model co-author increases over time with the need for academic diversity. Second, the 'innovation' keyword has the biggest center in the network, and over time, the lower-rank keyword which was in the former period has emerged as the top-rank keyword. Third, the cohesiveness group decreased from 12 before 2000 to 5 in 2015 and also the modularity decreased as well. Finally, examining characteristics of study area through a cognitive map showed that the relationships between domains increased gradually over time. The study has provided a systematic basis for understanding the current state of the business model research and the process of changing knowledge structure. In addition, considering that no research has ever systematically analyzed the knowledge structure accumulated by individual researches, it is considered as a significant study.

Reliability test is focusing to detect the unexpected reliability failure and solve them for the high quality of products. The test data should be used to assess and project the current level of interesting product reliability and so it is very important to have the accurately assessing methodology with test data. There are two type of trend for test data as constant and changing one during testing and this paper shows the difference in the assessing results of these two cases. There is less information how to define the existence of reliability growth rate changing and calculate the parameters of the reliability growth models to make an accurate assessment with such condition, so i established the process and mathematical model to calculate the parameters at such condition to make reliability growth curve with high Goodness of Fit. I validated the new method with the data made from Monte Carlo Simulation and case from Demko (1993). Even the assessed result with the new methodology may be different with the case by case because of very diversity in test condition and testing product quality, but the process and method founded in this research can be applied to any case using Duane and AMSAA model for their test data assessment. I also present the evaluation method to see the effectiveness with new one which is a conventional knowledge and not popular to use, so it is possible to compare the results with the newly presented and conventional method for better business decision.

Seoul has been the former capital from Joseon founded in 1932 by this time for 600 years. Seoul populated by some 10,290,000 people is the largest city in Korea. There are lots of cultural inheritance such as the castle town and 5 palaces including Gyeongbokgung in Seoul. Especially neungs(royal tombs) from 27 generations of king and queen in the Joseon dynasty during 518 years are very important cultural inheritance. The royal tombs were built from the castle town to the radius outside 4km within 40km pivoting on Seoul. Joseon royal tombs might have significant cultural value, which are representative Korean people's spirits for ancestor worship. After the 1945 Liberation of Korea those are having been managed by Office of Cultural Properties after Ministry of Education. This paper tried to find the changing process of the conservation and maintenance, the location of royal tomb area, the changing process of royal tomb, the area changing clue of modernization process, and in the historical city, Seoul. The royal tombs in the Joseon dynasty of the radius outside 4km within 40km pivoting on Seoul have been contributed to providing the metropolitan, Seoul population with the cultural and green spaces for 600 years. In the Joseon dynasty the royal tombs had been taken charge of thoroughly by the Royal Household with Neungchamboing system from Confucian background for ancestor worship. There after they had been damaged somewhat by the Japanese Imperialism period, the Korean War, and the pressure of urbanization. But the original state has been preserved well by state management. The royal tombs in the Joseon dynasty has been kept the culture of royal tomb's and memorial services with stone sculptures for 518 years. Also there are lots of documentary records of royal tombs. The memorial services of the tombs are held by Jongyakwon of Jeonju Lee family every year. The royal tombs somewhat damaged are needed to the original state of the transferred right of managing agency by the related national bodies.

The thesis is to look for the method of applying process drama for bilingual education in multicultural society. This purpose can be resolved in three steps: first, to understand the purposes and functions of education changing to multicultural society; second, to survey the need of bilingual education conformed to its purposes and functions; last, to understand the theoretical background of process drama and seek the method of utilizing it to bilingual education. Recently, the Korean society is also changing to multicultural society with international marriages and immigrant workers. But they have difficulties in communicating in Korean, and their children have even the same. Under the basis of multiculturalism wanting peace and mutual respect between cultural groups, they have to be educated in equality. This is why the bilingual education is needed in our society. Process drama, a widely used term for educational drama in Britain, claims its effectiveness for L1, L2 and bilingual education, for the principal medium in drama is language and what drama delivers is related to meaningful human experiences. It is also supported on script theory of linguistic therapy. Kase-Polisini classifies the developmental process of education drama into 1) planning, 2) playing and 3) evaluation. This process can be applied to educational drama for language as well. Rather, educational drama applying to bilingual education has even more availability with the varieties of group organization and subject matter. Conclusively speaking, the group of dual language schools can be organized into 1) mother-tongued group, 2) mother-tongued and L2 group, 3) multilingual group, or 4) L3 group in educational drama activity, as the class generally consist of the mixed multilingual children. And the subject matter can deal with 1) the Korean society and culture, 2) the society and culture of the purposed language country, or 3) the society and culture of the third nations.

During the last years it became more and more difficult to deal with environmental conflicts using traditional political instruments in industrialized countries. One reason for the occurring problems might be the citizens' awareness of scarceness of nature. Another reason might be the changing legislation with the introduction of the environmental impact assessment (EIA) as an integral part of a project's licensing procedure. The EIA offers new possibilities for citizens to interfere in decision processes and to obstruct projects. The changing situation requires new instruments for conflict solving. Mediation may be considered an alternative or completion to the traditional political instruments. It is a systematic strategy for conflict treatment and. with the support of an independent mediator, allows to reach an agreement among all parties involved. Mediation may be introduced in the EIA One possibility offers the scoping date, which, if the participation of the public is assured, might avoid heavy disputes in the further process. Another connection between the instrument of mediation and the EIA could be the use of the environmental impact study (EIS) as information background for a mediation process. EIA would then be source of information about all environmental aspects. Thus the role of EIA would be extended to being a part of conflict analysis in the alternative dispute resolution process.

The burning rates of combustible cartridge cases(CCCs) of 120mm kinetic energy ammunition were measured by CBT(Closed Bomb Tester). The burning coefficient was 1.4 for CCC fabricated by Post Impregnation(PI) process, and 1.0 for that by Beater Additive(BA) process. The BA process CCC showed the fixed burning coefficient of 1.0 in spite of changing the composition of CCC. As the Korean Future Main Battle Tank is requiring the high penetration performance compared with that of KlAl tank ammunition(K276), CCC was designed to have higher impetus composition than that of K276 composition(525J/g). The optimum impetus was 600J/g when considering the increases of pressure and muzzle velocity with increasing impetus. When impetus of CCC by changing the composition increased from 525J/g to 600J/g, the muzzle velocity of 12m/s at pressure increase of 3500psi increased in case of using SCDB propellant.

A structure of line for producing products is variously changing to be automatic and one-person Cell-Line considering the physical burden for workers in manufacturing industry of electronic goods. However, workers tend to still accuse Work-related Musculoskeletal Disorders (including shoulder, waist, hand, wrist, leg etc.) as a simply repeated work by accelerating of the production speed for productivity improvement in the assembly line. Thus manufacturing engineers in charge of changing and set up newly for an assembly line are necessary to the construct of the guideline on human engineering. Especially. There is no standardized engineering-guide and it is difficult to create the exact work environment because the risk factor analysis and the improvement for assembly line are executed once a year on the current situation. I'd like to reduce the physical burden on workers through the effective improvement of processing by the guideline on working environment fit for a characteristic on manufacturing process when the process is changed or newly installed.

본 논문에서는 H.264 비디오 스트림의 히스토그램 정보와 헤더 정보를 이용한 장면 전환 검출에 관한 연구이다. 비디오 데이터에서 장면의 변화를 검출하는 가장 일반적인 방법으로 히스토그램을 이용하고 있다. 그러나 히스토그램 정보를 이용하기 위해서는 비디오 데이터를 압축 해제 하여 각각의 장면에 대한 히스토그램 차이를 계산하기 때문에 연산 시간이 많이 소요된다. 반면에 H.264 비디오 헤더 정보를 이용하면 이러한 연산의 과정 없이 실시간 검출이 가능하다. 히스토그램을 이용하여 장면 전환을 검출하고 헤더 정보를 함께 이용하였을 때 동일한 프리시전 및 리콜을 수행하면서 검색 속도에서 향상을 확인할 수 있었다.
