The purpose of this study is analyzing the network of the National Assembly based on the bill data in 18th, 19th National Assembly lawmakers submit to Committees. By using bipartite projection we find out a strong committee and understand the relationship of committees. We focused on bills that ten or more of the legislators propose and compare between the first opposition party and the ruling party, which accounts for more than 80% of the overall structure of the National Assembly. We point out an influential legislator and committee in the network. This result presents which committees and lawmakers have a significant effect on process of legislation. This work gives a reasonable source as qualified to judge whether the committee and legislators group enact positively or not.

This paper aims to propose a research framework of analyzing voting activities of a national assembly on the basis of member-level voting similarity and provides a case study in the $18^{th}$ national assembly in South Korea. First, we propose a bill contentiousness measure that gives a higher score to bills for which ayes and noes are more diversified in both conservative and progressive parties. Based on the bill contentiousness measure, the top 5%, 10%, and 20% bills were identified and used for further analyses. Moreover, we propose a member-level voting similarity measure that compensates for the lower frequency of noes, and evaluate the pair-wise voting similarities for all lawmakers. Then, voting similarity differences to the affiliated/non-affiliated parties were analyzed for the members in the two major parties according to some internal/external key factors. Finally, similar voting groups were identified and their affiliations were investigated based on the multi-dimensional scaling (MDS) and network analysis techniques. A case study on the $18^{th}$ national assembly of South Korea showed that the cohesion of the members in the 'Hanara' party becomes higher than that of the 'Minju' party as the bill contentiousness increases, whereas the number of elected, local constituency versus proportional representation, and the competition intensity in a local constituency were found to be partially influential to the voting activities of lawmakers. In addition, MDS and network analysis showed that there is a distinctive difference between two parties when all bills are analyzed, whereas the diversity of parties increases in the same group as the bill contentiousness increases.

We apply a Bayesian estimation procedure to the analysis of roll call voting records on 2,389 bills processed during the 18th Korean National Assembly. The analysis of roll calls yields useful tools for to combining the measurement of legislative preference with the models of legislative behavior. The current Bayesian procedure is extremely exible, applicable to any legislative setting, irrespective of the extremism of the legislator's voting history or the number of roll calls available for analysis. It can be applied to any legislative settings, providing a useful solution to many statistical problems inherent in the analysis of roll call voting records. We rst estimate the ideal points of all members of the 18th National Assembly and their condence intervals. Subsequently, using the estimated ideal points, we examine the factional disparity within each major party using the estimated ideal points. Our results clearly suggest that there exists a meaningful ideological spectrum within each party. We also show how the Bayesian procedure can easily be extended to accommodate theoretically interesting theoretical models of legislative behavior. More specically, we demonstrate how the estimated posterior probabilities can be used for identifying pivotal legislators.

In this study we estimate the survival function of duration of the legislative processes in the 17th, 18th, and 19th National Assembly of Korea, and further analyze effects of the political situation variables on the legislative process. We define the termination of legislative process from a novel perspective to alleviate issues of dependency between censoring and failure in the data. We also show that the proportional hazards assumption does not hold for the data, and analyze data employing a log-normal accelerated failure time model. The policy areas of law agendas are shown to affect the speed of legislative process in different ways and legislative process tends to be prompt in times of divided governments.

This study aimed to investigate the political system related to the Electronic Government Law by analyzing the process of the common initiative of the law. To achieve the goal, this study applied the method of social analysis and sugessted the proper role of the assembly for realizing the electronic government and its control. The data were gathered from the bill information service of the national assembly. Netminer 4.0 was used for refining and analyzing data. The results are as follows. First, by analyzing three centrality(degree, betweenness, and eigenvector) of assembly member, the network effect of the powered party and reelected members were revealed as strong in the network. Second, through the component analysis, 5 sub-network has shown in total. The sub-networks showed two distinctive difference between two big parties. By the difference, members in two parties showed different characteristics in constituting communities and the effect of the powered party revealed as strong and clear. Based on the result, this study demonstrated the necessity of social solidarity rather than solipsism in committing common initiative. And a chronological research is need to anlayze $18^{th}$ and $19^{th}$ assembly to verify the effect of the powered party in prospect study.

In most democratic countries, influential professional interest groups often become a part of the iron triangle in the policy making process. One of the typical methods by which professional interest groups participate in policy making process may be by having interest group members in the national assembly, who are sympathetic to the group, implementing policies through legislation. In this study we found that from the Constitutional National Assembly through the 18th National Assembly, 147 members of the National Assembly of the Republic of Korea have been ex health care professionals. The research analyzed the roles of these members in health care law amendments as requested by the professional organizations. This study analyzed 11 major cases that involved nullification or amendment of legislations in favor of the healthcare profession, against the basic policies of the government. The study showed that in the 11 major cases, policies were amended in the direction intended by the National Assembly members and other organizations with similar interests, which was against the policy stance of the government. However, these cases did not unilaterally imply that the National Assembly has been captured by the interest groups through the legislators with health care professional background; rather, they should be perceived to be influenced by the exhibited loss of governability by the government in respect to healthcare policy decisions, loss of initiative due to lack of controllability, and reversals and inconsistencies of the policies.

Self-assembly of organic molecules is formed spontaneously on surfaces by electrostatic interaction with substrate. This research has shown that the self-assembly improves safety and handling tractability of high-energetic materials (HEMs). According to the recent study, control of the specific crystal size for reducing the internal defects is mightily important, because the internal defects are a factor in unstability of HEMs. In turn, we performed self-assembly of organic molecules and HEMs by using nano-sized HEMs, which were produced by drowing-out or milling/crystallization. Surface modification efficiency was decided by size distribution, zeta-potential, friction sensitivity and electrostatic charge.

The purpose of this study is to examine the significant factors having an effect on voting behavior of legislators in the FTA ratification votes of the 18th and 19th National Assembly. The previous studies show that the ideology and party affiliation of lawmakers are the most important factors influencing voting decisions of legislators. The study investigates whether these factors plays a significant role in voting on the FTA ratification. Statistical results show three important findings. First of all, we expected that the influence of the party variable be the most important factor due to the strong discipline of the Korean party. However, the results show that the constituency-interest variable is the most influential factor in the all analyses. Likewise, the results show that the influence of ideology variables on voting behaviors is very strong even though its impact is different by cases and models. This indicates that in the analysis of the voting behaviors of legislators, it is necessary to examine the effect of ideological variables in depth and in various ways. In addition, the results reasonably suggest that the party variable be consistently important even though its statistical significance is not shown in some models. Because the study analyzes the voting on the free trade agreement(FTA) bill, the results may not be commonly applicable to other voting behavior of legislator. Likewise, there is a limit to discussing the general characteristics of lawmakers based on the analysis on the 5 FTA ratifications. Nevertheless, the finding of the study is very significant. This is because it comprehensively analyzed the factors having an influence on the voting behavior of the legislators on FTA ratifications submitted to the National Assembly steadily since the 16th National Assembly. In addition, the study is very meaningful because it analyzed the ideological variables of the legislators in various perspectives considering that it is not easy in measuring the ideology of the lawmakers.

A stalking is becoming more diverse and the methods are developing over time as the society has changed over time due to the advancement of information technology but an initial countermeasure seems to be difficult as there is no sufficient legislations against such crimes as stalking. Our country passed laws regulating such stalking at 1999 and four more additional bills were proposed until the 18th National Assembly but they failed to become legalized. Two more additional bills were proposed during 19th National Assembly which are still pending. Crimes such as stalking violates and invades physical and psychological freedom of the victims and the crimes are severely inveterate and intentional. Advanced countries such as the United States, the Great Britain, Germany, and Japan enacted legislations that strictly regulates stalking and also appropriate responses. As these exemplary cases show, it is essential that our country also requires an effective legislations against crime of stalking and protecting a victim of the crime.

Background: The aim of this study was to describe the types of diseases that developed in semiconductor workers who have registered with the Korea Workers' Compensation and Welfare Service (KWCWS) and to identify potential common occupational characteristics by the type of claimed disease. Methods: A total of 55 semiconductor workers with cancer or rare diseases who claimed to the KWCWS were compared based on their work characteristics and types of claimed diseases. Leukemia, non-Hodgkin lymphoma, and aplastic anemia were grouped into lymphohematopoietic (LHP) disorder. Results: Leukemia (n = 14) and breast cancer (n = 10) were the most common complaints, followed by brain cancer (n = 6), aplastic anemia (n = 6), and non-Hodgkin lymphoma (n = 4). LHP disorders (n = 24) accounted for 43%. Sixty percent (n = 33) of registered workers (n = 55) were found to have been employed before 2000. Seventy-six percent (n = 42) of registered workers and 79% (n = 19) among the registered workers with LHP (n = 24) were found to be diagnosed at a relatively young age, ${\leq}40years$. A total of 18 workers among the registered semiconductor workers were finally determined to deserve compensation for occupational disease by either the KWCWS (n = 10) or the administrative court (n = 8). Eleven fabrication workers who were compensated responded as having handled wafers smaller than eight inches in size. Eight among the 18 workers compensated (44 %) were found to have ever worked at etching operations. Conclusion: The distribution of cancer and rare diseases among registered semiconductor workers was closely related to the manufacturing era before 2005, ${\leq}8$ inches of wafer size handled, exposure to clean rooms of fabrication and chip assembly operations, and etching operations.
