After the democratization movement in 1987, korean politics was transformed into three kim's politics by y Kim Yeong-sam, Kim Dae-jung and Kim Jong-pil. Before the time of three kim's politics, korean politics lasted for one long term, but three kim's politics made possible the peaceful regime change through political party integration and party coalition. The evaluation of three kim's politics coexist both positive and negative. The Positive political effects are diversification of political party composition and stabilization of regime change. Three kim's politics transformed the political party composition of Korea from a two-party system to a multi-party system, made possible a peaceful regime change through the unification of three parties and the DJP coalition. However, the negative political distortions of three kim's politics are the shortening of political parties and the concentration of political ideology. In three kim's politics, political party in Korea has a very short life due to the creation of political parties, the dissolution of political parties, the reorganization of political parties and the integration of political parties. Conservatism and progressive tendencies related three kim's politics were stabilized through Yeongnam region and Honam region. Therefore, three kim's politics means that the proportion of Korean politics is very high. Political effects and distortions derived from three kim's politics have become a challenge for Korean politics to overcome.

This research analyzed the status and problems of civilian expert programs for landscape architects to suggest alternatives to improve the current system. Literature research focused on the issues of the legal definition of civilian experts, the background of the program, and related regulations. Based on the understanding of the legal system, the research analyzed the operation status, structure, roles of the civilian expert program of local governments where landscape architects were delegated as civilian experts. Currently, 50 local governments are running the civilian expert program, and landscape architects are working as civilian experts in 11 institutions. The majority of landscape architects are working as MA or general architects. Only SMG runs an independent general landscape architect program. Based on the literature research and interviews with 16 experts, the research examined four main issues related to the program. First, the legal system issues of the civilian expert programs are related to the regulations assuming architects as experts. Revising the current legal system is a better alternative than promulgating a new law for landscape architects. Second, the compensation issue was a main problem related to operation. Securing a sufficient budget and more effective administration is required to solve the problem. Third, related to the role, the tasks being limited to consultation were regarded as the main problem. Although landscape architects wanted more opportunities to directly participate in the project's design, the fairness of the public project contracting system needed to be considered. Fourth, the competence issue is related to the number of available landscape architects. This issue can be solved by expanding the pool of civilian experts to adjacent disciplines, such as public design or landscape management.
Start-up accelerators are a new type of investor that provide mentoring, education and seed capital to start-ups for a fixed duration and receive a certain stake in them in return. They help start-ups achieve successful commercialization. With increase in performance visibility, the number of private and public sector accelerators rose across domestic and international markets. Private sector accelerators are established and operated by private entities while public sector accelerators are established and operated by the government. Both play complementary roles that are becoming increasingly important to start-ups. Therefore, this study aims to examine the differences in major operational goals and investment determinants between private and public sectors and to understand their implications. The results show that the private sector prioritizes profit generation through the investment, while the public sector aims to contribute to the development of high-growth start-ups, and create region-specific and technology-specific start-up ecosystems. Additionally, both groups consider customer needs the most important determinant. Public groups are more conservative in investments and tend to place importance on objective indicators such as patents, partners, mentors, and co-founders. Conversely, private groups value the capabilities of founders and their ease of collaboration with accelerators. These findings can help start-ups get support from public or private accelerators more easily. It will also help public and private accelerators refine the criteria for selecting start-ups.
This study conducted a survey of 265 dental hygienists working in Seoul and Gyeonggi Province from January 10 to February 28, 2021 to understand the ethical values and professional occupational characteristics of clinical dental hygienists. The difference in ethical values and professional occupational perception between subjects was post-tested using SPSS WIN 20.0 program and Scheffe test using independent sample T-test and one-way ANOVA. According to the results of the study, ethical thinking in ethical values was statistically significant in dental hospitals with higher final education, more work experience, and ethical work experience (p<0.05). The higher the age, the higher the final education, the more ethical education experience at university, the higher the sense of mission, the fewer working days, the more satisfying the job, the higher the organizational compliance with professional organizations and public service (p<0.05). The results of this study confirm the necessity of regular ethics education such as continuing education for dental hygienists, and are expected to be used as basic data to maintain ethical values and professionalism in clinical practice.
The present study was conducted to develop and validate a psychological scale that measures individuals' attitude toward unification of Korea (ATU-K). Building on major theoretical perspectives on the structure of attitude and the attitude-behavior link, we specified two sub-components each representing the cognitive and the affective dimension of people's attitude toward unification. In a survey that involved a stratified sample of Korean adults (N = 1,500), we found strong evidence showing the construct validity of the ATU-K scale. We also found evidence for the convergent and discriminant validity of the scale. In a second survey involving another stratified sample of 1,500 Korean adults, we found the utility of the ATU-K scale in predicting people's intention to engage in unification-oriented behaviors (personal/collective). We also found that the ATU-K scale fares better in predicting the intention vis-a-vis the other measures of unification-related beliefs reported in previous research. We discuss implications of our findings and directions for future research.
In order to provide the design criteria, the characteristics of consolidation for soft ground improvement have been investigated using the field banking test performed by the vertical drain method at the northern container section in Busan New Port. Field test results indicated that the estimated degree of consolidation in design stage decreased by about 7% compared with the measured one. This difference is attributed to the fact that the conservative geological properties were applied with relatively high amount of maximum clay mixture ratio during the design stage. Based on this findings, another laboratory oedometer test was implemented to consider various combination of mixture ratio. It was found that the consolidation degree increased in accordance with the increase of sand/silt mixture ratio. Also, the proportion of 10%, 50%, and 40% for sand, silt, and clay, respectively, was observed as the best combination of mixture ratio to the actual measurement, which is very similar to the average grain size distribution in the banking test area. Therefore, it is suggested that the overall geological characteristics as well as the grain size distribution should be considered in design stage to improve the soft ground that contains mixture of sand, silt, and clay.

As a part of study to develop LRFD (Load and Resistance Factor Design) codes for foundation structures in Korea, reliability analyses for driven steel pipe piles are performed and the target reliability indices are selected carefully. The 58 data sets of static load tests and soil property tests conducted in the whole domestic area were collected and analyzed to determine the representative bearing capacities of the piles. The static bearing capacity formula and the Meyerhof method using N values are applied to calculate the expected design bearing capacity of the piles. The resistance bias factors were evaluated for the two static design methods by comparing the representative bearing capacities with the design values. Reliability analysis was performed by two types of advanced methods: First Order Reliability Method (FORM), and Monte Carlo Simulation (MCS) method using resistance bias factor statistics. The static bearing capacity formula exhibited relatively small variation, whereas the Meyerhof method showed relatively high inherent conservatism in the resistance bias factors. Reliability indices for safety factors in the range of 3 to 5 were evaluated respectively as 1.50~2.89 and 1.61~2.72 for both of the static bearing capacity formula and the Meyerhof method. The target reliability indices are selected as 2.0 and 2.33 for group pile case and 2.5 for single pile case, based on the reliability level of the current design practice and considering redundancy of pile group, acceptable risk level, construction quality control, and significance of individual structure.
Various innovative technologies and methods are being applied to ensure the stability of steep rock slopes. However, there are design limitations concerning site ground conditions, leading to discrepancies between the designed and actual ground conditions during construction. In the case of the retaining wall in Yeosu, where the study area is located, although the construction of a 5-stage retaining wall is planned, at the current completion of the second stage, cracks on the upper part of the wall, settlement in the front of the wall, and seepage have been observed. After the completion of stages one and two, issues regarding cracks and settlement on the upper part of the wall and seepage in the front of the wall were discovered. Thus, there was a need to reevaluate the results of the existing stability assessment. It was confirmed that the issue was due to groundwater leakage, attributed to the lack of clear assessment of the colluvial soil layer during the initial design stage. Therefore, to conservatively reflect groundwater level conditions, a groundwater level contour was positioned at the top of the wall to conduct a slope stability assessment. The assessment results indicated that the safety factor during the rainy season exceeded the required value of 1.3, with a calculated safety factor of 1.31. However, during seismic events, the safety factor was determined to be 1.12, falling short of the required safety factor of 1.3. Therefore, it is suggested that the existing retaining walls constructed during stages one and two undergo reinforcement using methods such as micro-piles with grouting, and additional work should be carried out to ensure a clear assessment of the colluvial soil layer.
Pore water freezes in low-temperature compaction, which leads to different compaction characteristics compared to room temperature conditions. In regions like Alberta, Canada, where organic soils are prevalent, compaction performance is influenced by the high water retention and compressibility of organic soils, as well as their sensitivity to freezing and thawing. Alberta's strict environmental regulations demand the reuse of excavated soil for backfill, and the long winter season creates challenging conditions for civil engineering projects. In this study, a laboratory compaction test was conducted to evaluate the low-temperature compaction characteristics of organic soils with varying organic content. The results indicate that the optimum moisture content increases as the organic content increases, and the maximum dry unit weight decreases by up to 21.9%. In addition, under temperature conditions below -4℃, no optimum moisture content was observed, and the dry unit weight decreased as the moisture content increased.
Ginseng, a representative medicinal plant of South Korea, is also highly valued in North Korea. However, due to limited access to information about North Korea, the actual cultivation, research and development trends, and related industry status of ginseng in North Korea are not well known. In this study, we aimed to understand the current status and research trends of the ginseng industry in North Korea based on limited available literature. In the North Korean pharmacopoeia, ginseng is referred to as "Koryo ginseng" and is defined as the roots of 6-year-old ginseng cultivated in the Kaesong region. The pharmacopoeia includes 22 types of ginseng preparations. In addition, 10 ginseng preparations are included in North Korea's Essential Drug List, and various health supplements, cosmetics, and toothpastes containing ginseng have been developed, distributed, and sold. Since 2014, the ginseng industry and research in North Korea have become more active overall. During this period, the ginseng cultivation area in Kaesong has been significantly expanded, and the facilities have been renovated. The Kaesong Koryo Ginseng Processing Plant has been equipped with sterilized, modernized facilities since 2016 and has been in operation. Since 2017, there has been a growing interest in quality control research, leading to the introduction of quality management regulations and certification systems in 2019. In the 1990s, there was significant research on ginseng product development, and since the 2000s, studies on the pharmacological effects and clinical research of ginseng have been reported. Additionally, research on ginseng cultivation and ginseng processing industries to increase yield has been emphasized. Ginseng, as a representative medicinal crop of Korea, holds great importance for both South and North Korea. Given its significance and the potential for synergy through mutual cooperation, ginseng serves as an ideal subject for inter-Korean exchange and collaboration.
