The purpose of this study is to depict statistically and exploratively the interrelationship among learning orientation, environmental turbulence, and performance in the railway public organizations. To attain this purpose, a questionnaire was provided based on literature survey, and 616 respondent's data received was tested for its validity and reliability. And then, simple and vertical regression analysis were performed. The main findings are as follows: First, learning orientation has a relatively positive effects on performance. Second, environmental turbulence shows a partial moderating effects on the relationship between learning orientation and performance. These findings suggest that learning orientation do exist as an important organizational cultural dimension that contributes to the acquisition of sustainable competitive advantage, and some restrictive factors of public organizations seem to inevitably disrupt the intrinsic necessity of learning in the railway organizations.

Most innovation related theories including entrepreneurship theory regard the CEO's innovative competencies as the starting point of innovation. The study was investigated the relationship between CEO's innovation DNA and Innovation and the effects of environmental fit in their relation. For the empirical test, the sample was collected from 110 manufacturing companies in Daegu and Gyeongbook region. The results as follows: First, Innovation DNA has generally significant positive effect on innovation. The effect of discovery DNA is stronger than operating DNA to the product innovation, but the operating DNA stronger than the discovery DNA to the process innovation. The fit between CEO's innovative DNA and exogenous environmental turbulence make a strength innovation. The supplementary fit between discovery DNA and technology turbulence and complementary fit between discovery DNA and market turbulence reinforce product innovation. Process innovation were strengthen by the complementary fit between operating DNA and market turbulence.

The main purpose of this study is to depict the causal relationship among Market Orientation(MO), Marketing Capabilities(MC), and Organizational Performance(OP) with the moderating effect of Environmental Turbulence(ET), especially comparatively highlighting the differences between Korail and Subway firms. Findings show that there partly existed significant interactions effects between ET and MO in case of subway firms, whereas Korail did not reveal any significant results. When considering the strong relationship between MO and MC shown in the subway firms' case, it can be inferred that subway firms continuously have attempted to adapt to the external environment facing them more flexibly and actively over their counterpart, by which the degree of their MC became positively enhanced over Korail. These results give us some implication that MO should be internalized and also MC should get a higher consideration than ever throughout the railway public enterprises in order to strengthen their performance.

중국의 남중국해의 분쟁 도서 및 이에 속하는 배타적 경제수역과 대륙사면에 대한 주권과 '역사적 권리' 주장이 동아시아를 격변의 시기로 몰고 있다. 지난 수 십 년간의 중국의 놀라운 경제성장은 100년의 굴욕을 벗어나 '세계 강대국 복귀'라는 중국의 자부심 제고에 크게 기여했다. 그러나, 중국 정부는 지속적인 경제성장과 사회적 만족 유지에 필요한 자원 부족이 잃어버린 중국의 영광을 되찾는데 심각한 위협이 될 수 있음을 염려하고 있으며, 외국자원에 대한 의존성 증가를 그들의 사회적이며 경제적 안정과 자원안보의 심각한 도전으로 인식하고 있다. 2010년 이후 중국은 수차례에 걸쳐 남중국해를 중국의 "핵심 가치"라고 주장하고 있으며, 자원 부족이 중국에게 강압적 남중국해 전략 추진을 강요하고 있다. 본 논문은 자원부족이 중국에게 강압적인 남중국해 전략을 추진하도록 종용하고 있는 전략 환경에 끼친 영향을 분석해 보았으며, 또한 중국정부가 염려하고 있는 중국의 안정에 미치는 영향을 살펴보았다. 그리고, 중국의 자원부족과 이에 따른 강압정책이 중국, 동아시아 및 국제 사회에 미친 전략적 영향을 고찰해 보았다.

최근 격변하고 있는 국제해운동정을 볼 때 정치적 측면에서 흔히 남북문제로 일컬어지고 있는 선후진국간을 치열한 경쟁문제, 공산국상선대의 활발한 진출, 각국의 자국선 보호주의의 강화문 제등이 산적해 있으며 선대절약형 경제성있는 선박으로 전환되고 있으며 대체에너지 개발에 따른 LNG, LPG,석탄전용선이 유망분야로 지목되어 선진해운국들은 서서히 이 분야로 선대편성을 시도하고 있는 점등, 국제해운환경은 복잡다난한 양상을 띄고 있는 것이다. 이러한 추세하에 1979년 제 2차 석유파동이후 격심한 불황속에 있는 해운계의 실정으로 미루어 이에 대처하기란 용이한 과제가 아닌 것이다. 여기에 정부와 업계가 혼연일체가 되어 국제경쟁력제고를 위한 제 발전전략이 적극 검토 추진되어야 함은 물론이고 우리의 목표가 기필코 달성되어 민족의 번영과 복지국가건립의 소망이 성취되기를 회원 여러분과 함께 기대하는 바이다.

The competition for standardization in the enterprise environment starts with the data tier of the back-end and the standard enterprise middle tier is being stabilized by standardization as it is accepted as the Spring Framework. In addition, with the advent of new devices in an increasingly rapid cycle, securing compatibility with web and mobile services has become an important competitive advantage for web service companies. However, companies are unable to secure competent technical personnel appropriate for the rapidly changing environment of the information generation, and the curriculum of educational universities does not reflect the demand of new competency-oriented curriculum. Therefore, in this study, in order to acquire competency-oriented skills required for such an enterprise system platform environment and to develop a curriculum, the system using Spring Data JPA in the Spring Framework environment was implemented through documenting for each analysis and design step. It aims to provide a reference model for the full stack competency-based curriculum and capstone design curriculum that can be applied immediately in the enterprise environment.

Previous Earth Science textbooks have mostly lacked the latest astronomical phenomena frequently being reported in mass media such as popular science magazines. One of the main directions in the revision of the 2009 National Curriculum of Korea is to actively include those phenomena. Furthermore, despite a close link between astronomy and physics, the concept of modern physics has not been actively introduced in Earth Science textbooks and at the same time the linkage of physics to astronomy has rarely been studies in physics textbooks. Therefore, the concept of integration among different fields in science is emphasized in the new National Curriculum. Transient phenomena in the high energy astrophysical objects are examples that reflect such issue. The purpose of this study is to introduce transferring a real-time data and making imaging of astronomical observations using e-Science. As a first step, we performed the first experiment for a large data transfer of astronomical observation between Korea and Japan using KOREN, a National Research and Education Test Network. We introduce actively on-going fields of e-Science in observational activities of astronomy and astrophysics, and their close interrelationship with scientific inquiry activities and public outreach activities. We discuss our experiment in the scientific and educational aspects to the primitive e-Science activity in the Korean astronomical society and, in turn, provide a prospective view for its application to the scientific inquiry activities and public outreach activities in the upcoming commercial Gbps-level internet environments.

With mobile devices showing marked improvement in performance in the age of the Internet of Things (IoT), there is demand for rapid processing of the extensive amount of multimedia big data. However, because research on image searching is focused mainly on increasing accuracy despite environmental changes, the development of fast processing of high-resolution multimedia data queries is slow and inefficient. Hence, we suggest a new distributed image search algorithm that ensures both high accuracy and rapid response by using feature extraction of distributed images based on MapReduce, and solves the problem of memory scalability based on BIRCH indexing. In addition, we conducted an experiment on the accuracy, processing time, and scalability of this algorithm to confirm its excellent performance.

Despite the rapidly increased concern on the circularity of the program development activities in the social service agencies, there are only a few studies about the phenomena. This study is to describe the characteristics of program development in the process of adopting, developing, and disseminating the social programs and to figure out the factors influencing differences in the 3 activities in social service agencies. The researchers constructed an explanative model including each 12-13 independent variables with 3 consecutive dependent variables on the basis of reviewing the related literatures. A multiple regression analysis was applied to predict the features of the program development using 195 questionaries responded from social workers in community service centers. As the result of the descriptive analysis, the two noticeable features are found; (1) the agencies have very actively adopted outside programs, developed appropriate programs for the agency, and disseminated the programs into other agencies in the community. (2) there are some positive aspects of the factors in related to the process of the program development. The results of the regression analysis show that the three dependent variables of the adoption, development, and dissemination are very closely interconnected with each others, showing the evidence of the circularity in the agencies. In addition, the 5 independent variables at the value of p .01 are statistically related with the circularity of the three dependent activities. The implication of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

The ROK's military is attempting to change to advanced information science force through 'the Defense Reform 2020', which essentially creates the requirements of new military force. Therefore, the importance of defense industry and defense budget have been emphasized in order to successfully promote military build-up. However, the ROK defence industry has been going serious difficulties in the present day, and what is worse, unreliable rationality stability of Defense Capability Improvement Cost put the industry in the harder situation. In this circumstances, the improvement measures of the rationality stability of Defense Capability Improvement Cost should be immediately studied to satisfy the requirements of ROK military force in a suitable time and the development of ROK defense industry. The purpose of this study was to propose reinforcement measures to improve the arrangement system of yearly allocation for Mid-term Defense Plan of defense capability improvement programs and connect Mid-term Defense Plan to National Fiscal Management Plan to raise the rationality stability of ROK Defense Capability Improvement Cost.
