  • With the recent prediction of 'Cycle 25', the importance of space weather research increases. Accordingly, the World Radiocommunication Conference (WRC)-23 has adopted Agenda Item 9.1a) and carried out sharing researches between active/passive space weather observation systems and existing services. Therefore, in this paper, in order to increase the precision of space weather environment data and secure the frequency spectrum for observation systems, the direct interference effect from the weather radar in Gosan, Jeju on the space weather observation receiver in Hallim, Jeju, and the indirect interference on the observation receiver by diffraction and scattering from the radar target have been analyzed. As a result, it can be known that the radar direction, the propagation direction diffracted and scattered from the target, and the Rradar Cross Section (RCS) of the radar target, the reception area of the space weather observation antenna, and the antenna off-boresight are important parameters for the interference effect analysis.

  • Recently, solving industrial and social problems and creating new values based on big data and AI is being discussed as the main policy goal. The new government also set the digital platform government as a national task in order to achieve new value creation based on big data and AI. However, studies that summarize and diagnose discussions over the past five years are insufficient. Therefore, this study diagnoses the discussions over the past 5 years using the 4th industrial revolution as a keyword. After collecting news editorials from 2017 to 2022 by applying the text mining technique, 9 major topics were discovered. In conclusion, this study provided implications for the government's task to prepare for the future society.

  • This study analyzes the relationship since 1988 between National Assembly, president and political parties in Korea, and to find critical conditions for developing a mutually beneficial relationship among them. It argues that the levels of both internal power concentration and cohesiveness(or discipline) of political parties matter greatly, and applies them as theoretical framework for the historical review. By 2002, major political parties were highly concentrated in power and their discipline was strong. Consequently parties fought collectively with each other and Assemblies repeatedly saw standoffs and deadlocks. Reforms of 2002-04 that sought higher degree of party democracy and more autonomy among members of National Assembly have not been able to bring in a productive legislative-president relationship. A cohesive faction politics under the leadership of (potential) presidential candidates keeps it from growing. This study suggests further democratization of party power and more autonomy to individual Assembly members.

  • The purpose of this study was to investigate coverage patterns of the Korean internet news media on 'US-Iraq War' and its meaning and discourse structure. The internet news media was recently established and become a popular news media to compete with old news media in Korea. The author selected the 'Oh My News' as a representative internet news media for his analysis, and collected its news items from Mar. 20, 2003 to Dec. 17, 2003. on the basis of 4 different phases of the war. He analysed the whole of news items with various semiotic and discourse analytic methods, especially applying for Bell's concepts of time and discourse structure. As a result of this study, first of all, it was found that the 'Oh My News' tended to cover this war so different ways as the old news media did. It did not pay attention to the procedure of war, especially, battlefields, fighting between US and Iraq, damages and casualties. But, instead, it paid attention to many doubts about intention of US government and the President, Bush, dichotomous shift between pro-America and anti-America, rightness of dispatching Korean army into Iraq, etc. Secondly, it functioned as a kind of alternative media to speak up different voices comparing with those of old media. It tended to suggest different perspectives and opinions, while the old media tended to follow American perspectives and opinions. Thirdly, it became as a kind of new media setting agendas for this war in Korean society. It played a very important role for setting agendas for various issues related with this war. In conclusion, the internet news media has recently become a kind of new news media for suggesting alternative or different opinions, setting agendas, initiating discourses, etc., even though it still has may problems of becoming so called orthodox news media.

  • We investigated the conceptual and methodological characteristics of self-study as an innovational way with reflective research methods and explored the possibility of application of self-study in the field of science education by reviewing previous researches done in foreign countries. The results show that Self-study in education means the study of self, self-practice, self-thought, and so on in the teaching and learning context. It is a kind of new research method to pursue the improvement of teaching and learning practice with integrated perspectives on the context of instruction, identities of members, their beliefs and values, innovation agenda for better education, etc. This can be attained by collective and critical reflection in doing research. Most previous articles on the methodology of self-study suggested that the self-study should be more than just daily journals written only by her/him self. To do self-study in the academic way, they requested interaction with critical and cooperative colleagues, multiple but strict qualitative research methods, and participants' efforts for making better practice in instruction. Similar features to the above are found in the previous 14 self-study papers related to science education done in foreign countries. Based on the results, we concluded that self-study could be applied usefully into the field of science education in Korea. This paper could contribute to stimulation in the innovation of science instruction in a more practical way by increasing the attention to self-study and provoking its practice in Korea.

  • This study explores the interactive pattern among social issue, academic research, and governmental policy on science and technology during the last 20 years. In particular, we try understand wether the science and technology policy research and governmental policy meets social needs appropriately. In order to do this, we have collected text data from news articles, papers, and governmental documents. Based on these data, social network analysis and cluster analysis has been carried out. According to the results, we have found that science and technology policy researches tend to focus on fragmented technological innovation meeting urgent practical needs at the initial stage. However, recently, the main characteristics of science and technology policy research shows co-evolutionary patterns responding to society. Furthermore, time lag also has been observed in the process of interaction among the three bodies. Based on these results, we put forward some suggestions for upcoming researches in science and technology policy. Firstly, analysis levels are needed to be shifted from micro level to mezo or macro level. Secondly, more research efforts are required to be focused on policy process in science technology and its public management. Finally, we have to enhance the sensitiveness to social issues through studies on agenda setting in science and technology policy.

  • The issue of child care in family policy is one of the most important agendas. It is the primary task for a welfare state to form such conditions as socializing it to ensure labor rights and parental rights. The aim of this study is to review any controversies in the agenda of free choice in child care. But real 'free choice' comes true when all community members as individuals are able to enjoy their rights as both workers and parents without any restriction and sexual discrimination in the labor market. But in reality 'free choice' has not been realized in our society. This study is based on the analysis of these issues in free choice - the concepts of liberty, equity and equality, the role of the state, financial efficiency and the status of women in the labor market. Based on the analysis of the issues in accordance with the criteria, I suggest some policy recommendations: adequate and sufficient child care services, the introduction of univer sal child benefits and the expansion of public child care facilities.

  • This study focuses on Korea's traditional-style soryebok, in terms of its foundation, progression, and structural features. The research methods employed here include literature analyses of relevant laws and an official daily gazette, and practical analyses of artifacts and photographic documents. Especially, the artifacts of heukdannyeong(black uniform for officials with a round neck) in the form of chaksu(tight sleeves) were examined, which was regulated as soryebok in Eulmiuijegaehyeok. The term "soryebok" firstly appeared in "使和記略"(Sahwagiryak) written by Park Yeong-hyo, a foreign envoy to Japan, in 1882. Emperor's invitation written in the book asked him to wear daeryebok at the ritual and soryebok to the banquet. Soryebok was not adopted in Gapshinuijegaehyeok in 1884. However, several illustrated documents of the modern banquets at that time reveal that sabok, which was included in the 1884 reform, was used as soryebok. According to the Gapouijegaehyeok in December 1894, courtiers were required to wear heukdannyeong as daeryebok, and add juui(topcoat) and dapho(sleeveless coat) as tongsangyebok when they visited the royal palace. In Joseon's first daeryebok system, the term "tongsangyebok" that had been used in Japan was employed before soryebok was used. According to Eulmiuijegaehyeok in August 1895, the term "soryebok" originated from a costume ritual for courtiers of the Joseon Dynasty. Soryebok featured heokbannyeong chaksupo, samo (winged hat for officials), sokdae(belt), and hwaja (shoes for officials). There are around 24 artifact pieces of heukdannyeong in the form of chaksu(tight sleeves) in the following locations: garments of Prince Heungwangun and Wansungun, the court artifacts, Korea University Museum, Yun Ung-ryeol's family housed at Yonsei University, and Kyungwoon Museum. Artifacts have mu(godet) pulled back and a topcoat-like triangular mu. In conclusion, heukdannyeong, traditional-style soryebok has significance in the history of modern dress because streamlined traditional clothes and newly introduced Western dress system were able to be combined.

  • The future of ROK-US alliance has not been discussed in detail by both governments since early 2000s. However, it is becoming more apparent that ROK-US alliance is facing various daunting challenges. The new administrations both in ROK and US might have different perspectives about the future of alliance. In the process of resolving outstanding North Korean nuclear issue, the alliance can face challenges to change its fundamental features such as halting joint military exercise. ROK-US governments also agreed to transfer wartime operational control as soon as possible. All those factors indicates the growing necessity to articulate the future of ROK-US alliance. ROK and US needs to facilitate to dialogue for future alliance with the possible scenarios of changing security environment such as maintaining status quo, reconciliation of North and South Korea, and entering the reunification stage. In each phase, ROK-US has to develop the goal for the alliance, military institution to implement the alliance, role of USFK, and etc. It is imperative to develop the road map for future ROK-US alliance at this stage to avoid unnecessary folly.
