This study analyzes the entrepreneurship policies of the previous Korean administrations from the perspective of the Policy Paradigm by Hall(1993). A total of 195 newspaper articles and 202 government documents were examined to identify policy paradigm shifts through an analysis of policy objectives, policy instruments, and changing quality of policy instruments by each administration. The first paradigm was built during the 5th and 6th Republic, where 'Support for Small and Medium Enterprise Establishment Act' was enacted in 1986 to promote and support start-ups in the manufacturing sector. Next is the so-called 'people's government' period where 'Act on Special Measures for the Promotion of Venture Businesses' was enacted to tackle the challenges posed during the 1997 Asian financial crisis. A new policy goal was set to promote and nurture venture companies seeking subsequent means to achieve it. The third paradigm shift took place during President Moon's administration in order to effectively respond to the issues stemming from the fourth industrial revolution and the COVID-19 pandemic. Through the overall revision of the 'Support for Small and Medium Enterprise Establishment Act', the scope of startups were expanded, new industries and technology startups were supported and promoted, and venture investment-related laws were streamlined. In addition, the Small and Medium Business Administration was promoted as the Ministry of SMEs and Startups, enabling them to take initiative in implementing startup policies. Particularly, this study focuses on examining the low survival rate of startup companies and the revitalization of private investment as rising policy issues for recent startups, and suggests the improvement direction due to startup policy paradigm shift.

The Moon Jae-in administration insisted on reforming the prosecution for the reform of power institutions, and also tried to control the power of the prosecution through the establishment of a high-ranking public officials criminal investigation office. Then, what is the direction of the legal prosecution reform? Above all, it is a logic to drastically reduce the power of the prosecution. How to shrink it? First, it is necessary to control or check the power of prosecution and investigation that the prosecution has. Second, the key to the reform of the prosecution is perhaps to separate personnel rights from power. In order to exclude external pressure from the prosecution's personnel rights, there must be no instruction or intervention from the attorney general. To do this, the prosecutor general must go through various personnel evaluations, such as multi-faceted evaluation. Third, the essence of the High-ranking Officials Criminal Investigations Act is to deal with crimes of prosecutors, judges, police, and members of the National Assembly. It is also the core of the institutional mechanism to cover the corruption of one's family members while holding all the right to investigate, prosecution, and warrant claims, and to check the omnipresent prosecutors who have abused their right to investigate for political purposes. Then, what is necessary for the success of the high-ranking officials criminal investigation office? Above all, We think political neutrality is very necessary. The Ministry of Airborne has a very high authority of the Director. This paper intends to examine the functions and roles of the prosecution and high-ranking officials criminal investigation offices to prevent corruption. We analyzed the contents of the prosecution and the public officials criminal investigation office, and examined the limitations and problems, and the measures to control corruption in public offices.

This study analyzed the contents of changes in educational policy from the perspective of policy learning, based on the awareness of the lack of academic efforts to identify such phenomena despite repeated policy failures in educational policy. To this end, it has been more than 20 years since the policy was established, but it was analyzed using the policy analysis case of the teacher incentive policy, which still had severe conflicts between the government and teacher unions. As a result of the analysis, first, there were 11 changes in the policy content from the Kim Dae-jung administration to the Moon Jae-in administration. Whenever the government was newly launched, not only the contents of the policy for teacher incentives changed, but also the policy changes continued during the same government period. Second, when analyzing what kind of policy learning took place at the stage of change in each government's policy content, most of them were 'political policy learning' or 'instrumental policy learning'. Rather than a fundamental discussion about the goal of the policy, it has only repeated policy learning that adjusts only the ratio of differential payments to defend the teacher incentive policy. In order to recover from this current situation, this study suggests that it is necessary to present an alternative policy that can change the rigid society of teachers through 'social policy learning', which examines the basic values and strategies of teacher incentive policies.

This study is about the architectural changes over time in Dongchun-gotaek, the house of Song Jun-gil, one of the representative figures of the Hoseosarim(湖西士林), also an architectural cultural asset representing Daejeon. Data related to Sangryang(上樑) found in the restoration process of Dongchundang(同春堂) and DongchundangJongtaek(同春堂 宗宅), the state designated heritage application report written by Daejeon Metropolitan City, Deokeun-gaseung(德恩家乘), a book which has been handed down from generation to generation from Dongchundang Munjeonggongpa(同春堂 文正公派) of Eunjin Song's Clan and the results of partial excavation surveys respectively conducted in 2010 and 2020 were used as basic research data, and these data were compared and analyzed to examine the changes of the arrangement of Dongchundang, Jeongchim(正寢), and ancestral shrine buildings. Dongchundang was built by Song Jun-Gil. Rather than a new building, it was a building that was basically relocated to its current area when Cheongjwawa(淸坐窩), which was built by his father, dilapidated, and the timing of its construction can be clarified through Sangryangmun(上樑文). However, in the estimated area of Cheongjwawa, no exact site was found in two surveys of buried cultural heritages. In the case of Jeongchim, it was possible to confirm that it had been relocated two times, and it can be said that the biggest achievement of this study was to confirm that the first relocation was outside the current fence. In addition, one of the building sites which was identified in the excavation survey for confirming the servants' quarters was estimated to be the first construction at the site of Dongchun-gotaek. In the shrine area, there were the first constructed Gamyo(家廟), including Byeolmyo(別廟) dedicated to Bulcheonwi(不遷位), and Jomyo(祧廟) dedicated to Checheon(遞遷), and it can be seen that it was a space where many changes such as new construction, demolition, or mutual exchange of location occurred over time. The present buildings arrangement through these processes was not far from the original plan of Song Joon-gil. Therefore, the name of 'Dongchun-gotaek' is appropriate.

An organic radical polymer (ORP) was prepared by radical polymerization and following oxidation into nitroxyl radical. Two different oxidation methods were employed and their radical concentrations were measured using electroparamagnetic resonance spectroscopy (EPR) and UV-visible absorption (UV-vis) spectroscopy. From these measurements, $H_2O_2-Na_2WO_4$ oxidation method exhibited a complete oxidation, which resulted in 97.6% spin concentration. Also, it was revealed that convenient and cheap UV-vis measurement was useful for preliminary radical concentration comparison. After applied as a cathode material in lithium ion batteries, ORP electrode showed a high initial capacity ($110mAh\;g^{-1}$), a good initial efficiency (96%), a very high rate performance (70% charging during 1.2 min) and stable cycle performance.

This study aims to look for the proper directions of following and developing Gyeonggi sinawi dance in the fashion of Kim Sukja by closely examining its kinds and patterns. First, its characteristics and education reality were investigated. Second, the seven kinds of Gyeonggi sinawi dance Kim Sukja allegedly handed down (according to the 121st Report of the Intangible Cultural Assets) were concretely examined. Third, the composition of each dance pattern was studied. Fourth, various beats used in Gyeonggi sinawi dance were revealed. The late Kim Sukja had outstanding artistic talent and ability in Gyeonggi sinawi dance movements, musical composition, gayageum accompanied singing, and pansori episodes. Behind her were master singer Kim Seokchang (grandfather), father Kim Deoksun (belonging to Hwaseong Artist Board), shaman-mother Jeong Gwiseong, and great dancer Jo Jinyeong. Kim sukja's seven Gyeonggi sinawi dance types were bujeong nori, teo beollim, jinsoe, jeseok, kkaekkeum, ollimchae, and dosal puri (designated as Important Intangible Cultural Asset in 1990). Such beats as seopchae (dosal puri), mori, bal ppeodeurae, bujeong nori, ollimchae, jinsoe, and teo beollim (ban seoreum) were mainly used in Gyeonggi sinawi dance. In sum, Kim Sukja's dance was more than an individual's dance to represent the cultural types and life at that time in Gyeonggi-do and be a very important academic historic material. Therefore, it is the responsibility of the present generation to hand down and develop such invaluable traditional cultural materials.

On December 9, 2016, the decision of impeachment of the National Assembly decided against Park Geun-hye came from the nomination conflicts of the 20th general election between Pro-Park group and Anti-Park group at the ruling Saenuri Party. Therefore, this study focused on the nomination conflicts of the ruling party and the opposition party on the election results in the 20th general election on the public sentiment of the people. The nomination conflicts of the ruling and opposite parties were a prelude to the victory of the 19th presidential election, and it was serious faction conflict. Firstly, the study examined how the nomination conflicts of each party were centered on President Park Geun-hye as well as the leaders of each party and the chairman of the nomination committee. Secondly, the study examined what kind of changes would be made to the composition of presidential candidates for each party at the time of the presidential election. Thirdly, the study examined the opposition parties' separation between the Minjoo Party of Korea and the People's Party of Korea before and after the election and the issue of initiative in Honam. As a result of the analysis, the 20th general election failed to obtain a majority seat of the ruling Saenuri Party, and the opposition won and formed the majority. The reason why President Park and Saenuri were greatly defeated in the contest even in the situation where the opposition parties were divided is the root cause in the attitude of Pro-Park group and Anti-Park group who assumed their victory. Therefore, it is highly possible to render its responsibility to President Park Geun-hye, who has become a 'past power', and it has opened up the possibility that the emergence of future power by opposition parties. In the case of the opposition party, it is clear that the battle for Honam, which is a traditional opposition party's support group, is a matter of good fortune of the two major powers, Moon Jae In and Ahn Cheol Soo.
