  • 본 NEWASA 지역의 접수관정관개 개발에 따른 정제성분석 연구는 IBRD-EDI와 INDIA RESERVE BANK의 College of Banking이 공동주최한 Trainers Trining for Rural Finance (1985. 1.19-3.1)의 일환으로 1985. 2. 14-19 까지 NEWASA BLOCK에 대한 정수정관개의 경제적 효율성을 평가하기 위하여 농가조사를 실시하였고, 그 분석결과를 정리한 것으로 농지는 넓으나 농업용수가 부족한 본 지역은 빈곤과 저생산성 농촌잠재 실업을 특징으로 하고 있다. 농촌소득의 제고와 농촌실업의 고용확대는 전 인구의 80% 이상이 농민인 본지역뿐만 아니라 선언도 경제개발의 중심과제이다. 호당 6 acres 규모의 관개가 가능한 Dug-well Irrigation Development는 연평균 강우량이 650m/m에 불과한 인도의 Plateau 지역에서는 농촌빈곤과 실업문제의 해결, 토지 이용율제고를 통한 토지생산성 향상등 농촌경제개발의 중심과제로서 인도정부가 추진하는 핵심적인 농업정책이다. 본 지역의 농가호당 평균 소유농지연적은 8.67 acres(3.5ha)로써 모두가 Rainfed farming으로 현재 본 지역의 관개율은 17.5%에 불과하다. 농작물은 Jowar라고 하는 내한성 작물이 재배되며, 관개 조건하에서는 Jowar, Wheat, Sugarcane이 재배된다. With and Without Dug-Well Irrigation 조건하에서 각 작물별 ha당 생산성을 보면 Jowar는 0.86 ton/ha에서 2.22 ton/ha으로 증산되고 Wheat는 2.96 ton/ha, Sugarcane는 98.8 ton/ha이 생산된다. 한편 Dug-well Irrigation 전후의 농가소득의 변화를 보면 시행전의 4,275Rs가 되어 4배의 농가소득이 증가된다. 이와 같은 농업소득을 획득하기 위해서는 Dug-well에 대한 Initial Investment로서 33,400Rs(2,137,600원)이 투자되어야 하는데 종류별 융자 기간을 보면 Dug-well 15년(95%융자) Pump Set 9년(95%융자), Woriking capital 1년이며 인도의 Union Bank에서 융자하고 있다. 결론적으로 이러한 Dug-well Irrigation Development에 따른 IRR는 Before Financing시에는 29%이며 After Financing 시에는 24%이고 B/C ratio는 두경우에 있어 1.89, 1.24를 각각 나타냈다. 따라서, 본 사업은 재무적인 측면 즉 농가소득증대와 농촌고용증대 및 토지이용면에서 타당성이 크며 Dug-well Irrigation은 인도의 농업성장 및 경제개발의 관건으로 생각된다. 한국의 수리개발 기술 및 농업기술(Bio-chemical, Mechanical & Hydrological Technology)이 이전된다면 보다 괄목할 만한 농업발전이 이룩될 것을 생각된다.

  • Mycobacterium tuberculosis (Mtb) is one of the most successful pathogens to infect one third of world population. Th1-mediated immunity against Mtb infection is known as critical to express mycobacteriostatic function but it is not sufficient to resolve the infection. In this study, to verify the possibility Mtb itself change the gene expression to survive against host immune response, expression pattern of selected H37Rv genes, 16S rRNA, acr, fbpA, aceA, and ahpC, during the course of infection was measured with absolute quantitation method using real-time RT-PCR. The total number of transcripts of 16S rRNA increased during the course of infection, which was coincide with the increasing CFU. The total number of fbpA transcripts per CFU, which encode typical secreted Mtb antigen, Ag85A, increased for 10 days of infection before decreasing. The number of transcripts of acr per CFU, which encode heat shock protein, ${\alpha}$-crystallin, increased during the infection, and ahpC and aceA, they both are enzymes produced in oxidative stressful condition, increased for 20 days and then slightly decreased on day 30. These findings are one of survival strategy of pathogen evading host immune response lead to persistent infection inside host cells.

  • The purpose of this study is to develop and validate the measure of individual Servant Leadership Quotient (SLQ). For the purpose, a total of 100 questions were composed based on the relevant literature and previous studies. As a result of exploratory factor analysis, it was classified into five factors, and the final choice corresponds to 40 questions. The first factor comprises thirteen items reflecting listening (5 items), empathy (4 items), healing (4 items), and the second factor consists of nine items which are futuristic view (2 items), stewardship (3 items), commitment to the growth of others (4 items), community building (4 questions). The third factor is conceptualization (5 questions), the fourth factor is recognition (5 questions), and the fifth factor is persuasion (4 questions). The reliability of the final selected items was .97, and there was a statistically high correlation between the overall Servant Leadership Quotient and the subfactors within the range of r = .788 ~ .872. As a result of one-way ANOVA to find out the relationship between demographic variables, the overall Servant Leadership Quotient was not different according to gender, but it was significantly different among elementary, middle, high school students and adults. As a result of the post-test, there were no differences among the student groups (elementary and middle school) in the overall Servant Leadership Quotient, but there were differences between the early adult and middle adult groups. This study is meaningful because the questions are structured to measure individual Servant Leadership Quotient (SLQ), which goes beyond the scope of groups or organizations Servant Leadership Quotient.

  • As the network-related technology develops the number of both Internet users and the usage are explosively increasing. The networking traffic is increasing in the campus as the networking system inside universities, following the trend, adds more nodes and various networking services. Nonetheless, the quality of services for users has been degraded. Accordingly, core problems, which can cause troubles for network management, design and expansion of the network, and the cost policy, has appeared. To effectively cope with the problems with analyses a great number of technicians, tools, and budget are needed. However, it is not possible for mid and small-sized colleges to spend such a high expenditure for professional consulting. To reduce the cost and investment creating the optimized environment, the analyses on the replacement of the tools, changing the network structure, and performance analysis about capacity planning of networking is necessary. For this reason, in this paper, framework-based performance management tools are used for all steps that are related to the subject of the analysis for the network management. As the major research method, the current data in detailed categories are collected, processed, and analyzed to provide the solution for the problems. As a result we could manage the network, server, and application more systematically and react efficiently to errors and degrading of performance that affect the networking tasks. Also, with the scientific and organized analyses the overall efficiency is upgraded by optimizing the cost for managing the operation of entire system.

  • Due to the increasing demands on the efficient use of land and the fast growth of construction technologies, human living space is expanded from on the surface to above and under the surface. By recognizing that the current cadastre system based on 2D was not appropriate to reflect the trend, the researchers are interested in a 3D cadastre. This paper proposed the 3D cadastre data model that is appropriate to protect ownership effectively in Korea. The 3D cadastre data model consists of a 3D cadastre feature model and a 3D cadastre geometry model, and the data are produced by a 3D cadastre data structure. A 3D cadastre feature model is based on 3D rights and features derived from case studies. A 3D cadastre geometry model based on ISO19107 Spatial Schema is modified to be good for 3D cadastre in Korea. A 3D cadastre data structure consists of point, line, polygon and solid primitives. This study finally purposes 1) serving and managing land information effectively, 2) creating rights and displaying ranges about infrastructures above and under surface, 3) serving ubiquitous-based geoinformation, 4) adapting ubiquitous-based GIS to urban development, and 5) regulating relationships between rights of land and registration and management systems.

  • Children in one-parent families have difficulties from negative perception and prejudice in society in spite of increasing divorce rate and the substantial number of one-parent families. This research aims to provide basic setting-up materials of the equal educational environment to children in one-parent families by examining teachers' perception and attitudes towards those children, and also analysing which factors are associated with the teachers' perceptions and attitudes. In particular, by exploring teachers' internalized value system and stereotyped conception are closely related to the process of evaluating children's personality and behavior, this research suggests that social consciousness to one-parent families should be changed and improved in terms of equality. According to the research result, most teachers notice that children in one-parent families are increasing by number at schools, however, they do not seem to understand properly children's situations including psychological condition. Teachers' negative perception of children in one-parent families are not only influenced by teachers' socio-demographic characteristics, experience factors and children's school life, but also by teachers' own personal value of familism and divorce. Such teachers' attitudes towards one-parent family children are easily predicted to influence children's confidentiality and self-respect. Therefore, it is proposed that the change of social consciousness on one-parent families, the change of educational system and educational environment, development of educational training program for teachers, allocation of school social worker or school counsellor, and empowerment of one-parent family are necessary in order children in one-parent families to have more equitable opportunities at school.

  • Songguk-ri site gained academic recognition by the excavation of stone coffin tomb with a bronze dagger in 1974. And it is confirmed that this site is epoch-making in Korean bronze age through the following excavation started in 1975. But the excavation reports published until now do not have even overall view of this site, thus it is difficult to get the whole picture of this site. Thus, in this paper the author reexamined all reports on this site and by making the map of overall view and distribution of archaeological features as a basic research. Moreover, I analyzed also artifacts from this site, and compared with the recent papers written by other researchers about the chronology and character. Songguk-ri site has livelihood domain which consists of dwelling pits, attached features, storage pits, pot-firing features, wood fence, abatises, buildings above ground, as well as cemetery which consists of stone-coffins, jar-coffins, pit tombs. Trace of making large terrace was also excavated. These features seem to belong to the same archaeological stage, dated about B.C.850-550, according to C14 dating. On the other hand, the intensification of wet-rice cultivation made this group more productive. Based on this financial strength, some influential group emerged they constructed defensive settlement to protect their products safely. Besides it seems that there were frequent occurrence of conflicts. However, we can know that they kept their stable life, through the expansion of living space. Consequently, Songguk-ri site played a role of the summit among some settlement in this area.

  • With increasing interest of health due to population aging, medical device industry is highlighted as a promising industry. However, Korea medical device industry is not enough market competitiveness compared to global company due to a narrow domestic market and a small company structure. In order to retain the national competitiveness, it is necessary that we have to derive a central technology and its trend. This study has predicted a central technology for medical device industrial using patent network analysis. The central technology is defined as a key technology that is connected to most other technologies and that significantly affects them. For the empirical study, we conducted social network analysis using covariance and correlation coefficient between IPC codes extracted from medical device patents, introduced by Jun(2012). A social network is a social structure of diverse items as well as of human beings. In this study, we set each medical device as a node in an SNA and analyze the Degree values between them. Also, Korea health industrial statistics system are utilized for verification of selected central technology. As a result, we found that the central technology is located on the medical device items, which are listed higher the amount of production. The central technology selected through the proposed methodology will provide a inspiration for establishment of R&D policy.

  • As Korea experienced a Asian foreign exchange crisis in 1997 and a world financial crisis in 2008, the social structure of Korea has undergone many changes. The problem of polarization has become more serious, and the social class has become harder to move between strata. This problem has been accompanied by a growing sense of crisis that the power of social development can be lost along with the problem of population cliffs. Behind the crisis is a reflection of the fact that the growth-oriented economic policies and welfare policies implemented in various European countries can not solve the problem. As an alternative to this, the emergence of social enterprises is attracting attention. Social enterprises have the characteristic of seeking to generate economic profit in order to achieve the purpose of the public interest to provide jobs to the underprivileged. In recent years, the importance of social ventures to expand the scope of new social enterprises in innovative ways has increased. The social venture is a venture business in that it takes risks to develop new areas, not existing business areas, but it also has the character of a social enterprise to achieve the public interest. In other words, an innovative corporate model that provides a creative and challenging solution of social problems in the venture spirit. Although the interest and importance of social enterprises and social ventures are increasing, this academic research is still lacking. The purpose of this study is to introduce and analyze cases of successful social enterprises and social ventures in order to reflect these social interests and their importance and to fill the gap of previous studies. In addition, I hope that this study will stimulate interest and research on the start - up of social venture.
