This article analyzes the influence of sectoral system of innovation(i.e. technological regime, market demand, networks, and institution) on innovative performances(i.e. product-, process-, organizational-, marketing-, and environmental- innovation) in Korean environmental industry, conducting a multiple regression analysis based on survey data from 201 Korean environmental companies. As the results, product innovation is positively influenced by internal technology accumulation and market demand response, while not affected by external knowledge utilization, market competition, networks among market and non-market agents, government support and regulation. Process innovation is positively influenced by internal technology accumulation, networks among non-market agents and regulation, but not by external knowledge utilization, market demand response, market competition, networks among market agents, and government support. While organizational innovation is positively influenced by internal technology accumulation, external knowledge utilization and regulation, it is not affected by market demand response, market competition, networks among market and non-market agents, and government support. While marketing innovation is positively influenced by internal technology accumulation, networks among non-market agents, and government support, it is not affected by external knowledge utilization, market demand response, market competition, networks among market agents, and regulation. Environmental innovation is positively influenced by external knowledge utilization and regulation, but negatively influenced by market competition. It is not affected by internal technology accumulation, market demand response, networks among market and non-market agents, and government support. Such results suggests the following policy implications. First, it is necessary to expand the sphere of relating markets through the application of convergence technology, new regulations, and overseas markets. Second, reinforcing ecosystems among environmental market agents through demand-linked joint R&D should be revitalized. Third, it is needed to strengthen more supporting policies rather than regulation. This article has the limitation of using the survey data. And further researches on the environmental sectoral system of innovation structure itself will be tried.

Objectives: The neighboring countries of South Korea and Japan in Northeast Asia have interacted in both positive and negative ways, at times as close partners and other times adversaries, throughout their long and thorny history of extensive dynamics. The controversial dispute over Dokdo is one of the most critical issues evoking harsh tensions and arguments asserting wholly opposite claims. Dokdo is a small island between two coastal states, but significant in terms of territorial, botanical, and marine resources, and thus ownership of the island has become a point of conflict accompanied by a troubled history. But why has Dokdo been a source of conflicts and how should the controversial Dokdo issue be addressed in a way that fosters positive influence and co-prosperity? Methods: This study provides comprehensive and critical insights from a wealth of previous research and strategic suggestions for the Korean government. It utilizes the three perspectives of historical documents and political context, international regulations and legal frames, and public diplomacy. Furthermore, it applies these resources to negotiation theories and strategies to propose reasonable solutions. Results: This study suggests that it is important for Korea and Japan to try to build mutual trust through more active communication and interaction in order to understand each other before attempting to create a formal resolution via negotiation. In addition to these efforts, Korea needs to be ready for the inevitable need to take decisive action in terms of negotiation, using analytic and efficient strategies. The study proposes three solutions: 1) Strong Action Strategy, 2) International Legal Strategy, and 3) Public Diplomacy Strategy. Conclusions: From the perspective of public diplomacy, the Dokdo issue needs to be converted from a symbol of conflicts between Korea and Japan into a symbol of peace and co-prosperity. In addition to promoting a positive relationship between the two states, it can also contribute to the security environment of the Northeast Asian region and global peace.

In the era of the 4th industrial revolution, high technology is causing many changes in modern society and economy. Among them, changes in industries and jobs require new competencies of future human resources. As an educational alternative to these changes, maker education and design thinking methods are spreading around the world, and it is necessary to actively apply such education in university curriculum. Therefore, this study examines the effects of the maker education using the design thinking method on the learners' competencies required as future human resources and, relationship between the development of university students' entrepreneurial competencies and learners' competencies. And the purpose of this study is to contribute to the vitalization of entrepreneurship education for university students by suggesting an educational model. For this purpose, this study investigated the prior research on maker education/environment and design thinking methods to examine concepts and characteristics, and analyzed the influences between maker education/environment and design thinking methods and the development of learners' personal, social and technological capabilities. In addition, this study analyzed the relationship between learners' developed capabilities and university students' entrepreneurial capabilities, and based on the results, suggested directions and conceptual models for education that combine maker education/environment and design thinking methods. In conclusion, maker education/environment and design thinking methods in university education have a positive effect on the cognitive, social, and technological development of learners, and this has a significant relationship with the factors of personal, social, and technological dimensions of university students' entrepreneurial competency. It is analyzed that it has a positive effect on the promotion of entrepreneurship activities of university students. Therefore, it is judged that university's interest and support should be given to the vitalization of maker education using the design thinking method for university student entrepreneurship education and future human resources nurturing.

A vast amount of riverine spatial dataset have recently become available, which include hydrodynamic and morphological survey data by advanced instrumentations such as ADCP (Acoustic Doppler Current Profiler), transect measurements obtained through building various river basic plans, riverine environmental and ecological data, optical images using UAVs, river facilities like multi-purposed weir and hydrophilic sectors. In this regard, a standardized data model has been subsequently required in order to efficiently store, manage, and share riverine spatial dataset. Given that riverine spatial dataset such as river facility, transect measurement, time-varying observed data should be synthetically managed along specified river network, conventional data model showed a tendency to maintain them individually in a form of separate layer corresponding to each theme, which can miss their spatial relationship, thereby resulting in inefficiency to derive synthetic information. Moreover, the data model had to be significantly modified to ingest newly produced data and hampered efficient searches for specific conditions. To avoid such drawbacks for layer-based data model, this research proposed a relational data model in conjunction with river network which could be a backbone to relate additional spatial dataset such as flowline, river facility, transect measurement and surveyed dataset. The new data model contains flexibility to minimize changes of its structure when it deals with any multi-dimensional river data, and assigned reach code for multiple river segments delineated from a river. To realize the newly developed data model, Seom river was applied, where geographic informations related with national and local rivers are available.

In the era of knowledge-based society and glocalization the new role and mission of universities is of increasing concern to us. Studies of the successful universities suggest that there are many ways for the future development of universities, for example high qualification, specialization, and internationalization of universities etc. In this context we can also focus particularly on the regionalization of universities in terms of the university as a regional builder. This paper aims to identify the interactions between universities and regions and to explain their's contributions to the regional developments. The result of analysis shows that the university-region interaction is a win-win strategy both for university and for region in the rapid changing social-economic, administrative and educational environments, and more systematic and stepwise approaches are required to ensure a mutually beneficial collaboration.

Once drought occurs, it results in the extensive affected area and considerable socio-economic damages. Thus, it is necessary to assess drought risk and to prepare its counterplans. In this study, using various observation data on meteorological and socio-economical factors, drought risk was evaluated in South Korea. To quantify drought risk, Drought Hazard Index (DHI) was calculated based on the occurrence probability of drought, and Drought Vulnerability Index (DVI) was computed to reflect socio-economic consequences of drought. Drought Risk Index (DRI) was finally suggested by combining DHI and DVI. These indices were used to assess drought risk for different administrative districts of South Korea. The overall results show that the highest drought risk area was Jeolla Province where agricultural practice is concentrated. The drought risk map proposed in this study reflects regional characteristics, thus it could be utilized as a basic data for the establishment of drought preventive measures.

신호교차로 운영 최적화를 위한 4가지 변수인 주기, 현시순서, 현시녹색시간, 옵셋 중에서 지금 지 정형화된 지침이 없이 전문가의 경험이나 휴리스틱한 규칙(Heuristic rule)에 의해 결정되었던 현시순서에 대해 다양한 교통조건을 고려하여 최적현시와 지체변화를 분석하였다. 교통조건은 독립/연동교차로, 교차로 기하구조, 비혼잡/혼잡상태, 통과교통량에 대한 좌회전 교통량비(LT/Thru)에 따라 Dual ring에서 구현가능한 모든 현시순서를 대상으로 최적현시를 도출하였다. 분석과정에서 비혼잡상태의 경우 LT/Thru가 작을수록 직진 중첩 동시신호가 가장 우수하게 나왔으며, LT/Thru가 크게 증가할수록 선행양방향좌회전이 양호하게 나타났다. 혼잡상태의 경우는 LT/Thru 15%에서 공통적으로 최적현시가 변하였는데 이는 포화도와 이동류별 녹색시간비율이 크게 변하면서 급작스런 주기 증가에 기인한 것으로 판단되었다. 또한 독립교차로 및 연동교차로 현시순서 분석 결과를 보면 전반적으로 선행양방좌회전 현시와 직진 중첩 동시신호 현시가 가장 양호한 것으로 나타났으며, 양방 동시신호 현시는 대체로 지체가 높게 나타나 신호운영에 비효율적인 것을 다시 한번 입증하게 되었다. 특히 연동교차로에서는 연동에 중요한 요소인 옵셋과 진행대폭(bandwidth)의 상호관계를 탄력적으로 대응할 수 있는 직진 중첩 동시신호가 최적현시로 나타났다. 본 연구는 검지기가 설치되지 않은 고정식 신호기로 운영되는 지방부 및 도시 가로망의 교통류 효율성을 높이는 중요한 자료로 사용될 것으로 판단된다. 최근에는 실시간 교통신호 제어시스템이 활발히 연구. 운영되고 있는데 이 시스템 내에 포함되어 있는 TOD방식의 고정시간 제어(pretimed control)나 패턴선택제어(pattern selection control)에도 충분히 활용할 수 있을 것으로 사료된다.

This paper studied the source coding rule of the characters to minimize the HDB-3 scrambling for UTF-8 code. An existing source coding rule of the characters to minimize the HDB-3 scrambling in the line coder is for the source codes which are directly entered into the line coder without any transformation. Therefore the existing source coding rule can't apply the UTF-8 code which is directly came into an input of line coder. The reason is that the scrambling code in the source codes are not same as UTF-8 codes. So, if they want to analysis the scrambling occurrence situation in UTF-8 codes and make an unscrambling UTF-8 code, they should make a UTF-8 code table for the source codes, find out the scrambling occurrence codes and then encode the unscrambling source code. The source coding rule for UTF-8 code showing this paper can omit such a complicated procedure to encode an unscrambling source code.

This study is to classify the somatotypes of middle-aged women by many critera and figure out he characteristics of each somatotypes. The subjects are 614 middle-aged women between 35 and 59 years old and the research is based on anthropometric and photometric measurement by photographing their body parts. The results are as follows; 1. The result of factor analysis indicated that 11 factors were extracted through factor analysis and orthogonal rotation by the method of varimax and those factors comprised 85.71 percent of total variance. 2. As the result of cluster analysis the group of the middle-aged women is classified as 6 types. Type 1 is short, fat, H type in front and lean-back type on the side. Type 2 is standard in height and weight. Type 3 is standard height, fat, long upper body, bend-forward type and protrude of the hip on the side. Type 4 is tall, thin, short upper body, having clearly protrude of the back and hip and lean-back type on the side. Type 5 is neither short nor tall, slim, X type in front and I type on the side. Type 6 is tall, thin and B type on the side. 3. As the result of observing the mutual corresponding relation between these 6 groups and age/Rohrers Index, the somatotype of the middle-aged women is divided at the age of 45. Accordingly when it comes to progress the study of the middle-aged women in the future, we will have to observe the characteristics for dividing the first half and the second half of age of 45.
