The subject heading is an elaborate access tool for subject browsing and searching in information retrieval environment. The purpose of this study is to suggest the applicable facets to subject headings in Korea. First, the concepts of subject and the definitions of facets were investigated in the literature review. Second, six cases including OCLC's FAST, PRECIS, "Thesaurus construction and use", CC $7^{th}$ edition, BC $2^{nd}$ Edition, and UDC $3^{rd}$ Edition were analyzed to focus on configuration of facets as case studies. Based on the results, twenty-two facets were proposed including Topical, Event, Geography, Chronology, Personal and Corporate Name, Title, Form, Genre, Language, and Person facets as 11 top facets. Also, Topical-Thing/Entity and Topical-Action/Status, Part, Kind, Property, Whole, Material, Patient, Product, By-Product and Agent facets as sub-facets of Topical facet.

This study examines factors that influence adolescents' political trust in Asian societies with special emphases on authoritarian orientations and corruption perception. Previous studies on adolescents' political trust have focused almost exclusively on Western societies. As a result, the impact of other cultural values that are specific to Asian societies, such as authoritarian orientations, on adolescents' political trust has received little attention in the existing literature. Moreover, situated within a socialization framework which argues that political trust is an extension of interpersonal trust, much prior work has ignored the role of adolescent evaluations of institutional performance in generating political trust. The data I use offer empirical evidence that both authoritarian orientations and institutional performance-especially its ability to curb corruption-are independent sources of political trust among Asian adolescents and that the trust-eroding effect of corruption is less salient among Asian adolescents adopting more authoritarian orientations. Additionally, the evidence also suggests that corruption perception is a more important factor than authoritarian orientations in shaping adolescents' political trust in more economically developed countries while the reverse pattern is found in less developed countries.

Sunscreen is a product that blocks and scatters UV rays to protect them from UV rays. Domestic consumers generously invest in sunscreen, ranking first in the world in terms of sun care consumption per capita in 2019. Sunscreens are subject to a variety of factors, including regulations, ingredients, formulations, clinical trials, and product labeling, but are tightly controlled as product demand increases. In this study, various factors affecting the UV protection factor were investigated and analyzed. Preemptive measures such as continuous investigation are required so that various factors such as these do not become obstacles for domestic cosmetics companies to export, and to revitalize the export market with international competitiveness.

The study is purposed to investigate the current status of assistive technology devices(ATDs) and to explore ways to improve the ATDs support system for work. As a method, domestic and foreign systems were investigated to derive implications can be applied in Korea based on the analysis framework that compromised Gilbert and Terrell's policy analysis model and research purpose. Next, a survey was conducted on 202 disabled supported ATDs for Work. They were looking for a job or working. We would like to suggest a plan as follows. First, it is necessary to improve the support process centered on consumers. Second, the expansion of items and supplementation of the quality management system should be considered. Third, it is urgent to expand the application qualifications. Finally, the foundation for improvement should be continuously laid. We expected the direction of improvement of the support system will be established.

Using 2006~2015 Korean Welfare Panel Survey data, this study analyzed the poverty reduction effects of social security benefits. The results show that social security benefits have substantial impacts on reducing the poverty gap. National Basic Livelihood Security, public pensions, and Basic Pension have relatively larger poverty reduction effects. Other benefits such as disability benefits, workers' compensation unemployment insurance, and childcare subsidies have much smaller poverty impacts. Two determining factors of the poverty reduction effect are (1)the amount and (2)the poverty reduction efficiency of social security benefits. With the expansion of the social security system in recent years, the poverty reduction efficiency has decreased in general. Due to a greater increase in the amount of benefits, however, the poverty reduction effect has gradually increased. In order to increase the anti-poverty effect of social security, it is important to find ways to improve efficiency while minimizing the disadvantages of the selectivistic welfare benefits.

In this paper, we investigated the international guidelines and actual disposal maneuver cases to prepare KOMPSAT-2 post mission disposal. And then, disposal maneuver plan was established using current propellant of KOMPSAT-2 and verification was also performed to find out whether the international guidelines are satisfied. As a result, the lifetime of KOMPSAT-2 was 3.6 years when 45kg propellant was used to decrease perigee altitude to 300km. And if more than 14.5kg propellant consumed for same strategy, KOMPSAT-2 can satisfy the international guidelines. Finally, re-entry survivability analysis was performed and it represented that heat resistant objects, such as propellant tank and reaction wheel, could be survived but total ground casualty probability was less than international guidelines.

The purpose of this study is to estimate the macro-economic ripple effect of tax exemption for both high end technology firms and research enterprises in R&D special cluster. We apply the user cost of capital model and the Input-output model to the estimation. Estimation results for 2007-2016 are as follows: the increase in both the production and the value-added is 2,807 and 1,392 hundred million Korean won, respectively. Also, employers are increased by 2,355 people. These imply that keeping the tax exemption item for certain enterprises in R&D special cluster may be beneficial to our economy.

This study aims to extend fundamental categories from Clause 11, "facet analysis" in International Standards for thesaurus(ISO 25964-1) by analyzing fundamental categories of Clause 11 and concept and their scope in a thesaurus of Clause 5. For to do this, the fundamental categories were established by adjusting partially and adding mental entities explicitly referencing the highest concepts(YAMATO which is the upper ontology of Mizoguchi, and ISO 2788) and existing fundamental categories(PMEST, FRBR group 3 entities, 13 categories in CRG). Also, established fundamental categories were reorganized and structured based on concreteness/abstraction of PMEST in Ranganathan and independence/dependence of YAMATO in Mizoguchi. And the upper categories were divided into independent and dependent entities. Under these entities 28 criteria are included in the independent ones and 2 criteria in the dependent ones. In the further study, the result of this study can be expected to reuse and refer as controlled vocabulary in the field like classification, taxonomies and thesauri where expected to utilize fundamental categories and as the high-level concept when constructing an ontology for information retrieval.

This study aims to analyze the current state of the operation of the information disclosure system in the judiciary of Korea to identify problems and suggest ways to provide more effective and substantive requests for information disclosure in the future. To this end, we reviewed the court's information disclosure claims process from 2007 to 2017 using the data published in the judicial yearbook and the data charged to the court information disclosure system of Korea. Results showed the different processes according to the person in charge, the high withdrawal rate, the complaint response rate, and the trend of the information nonexistence as the common problems. To solve these issues, we proposed to improve the various claims system, strengthen the education of the information disclosure claimant, publish the manual, and expand the provision and original text of information in advance.

In this paper, an algorithm for determining the coagulant input rate in the drug-injection tank during the process of the water purification plant was derived through big data analysis and prediction based on artificial intelligence. In addition, analysis of big data technology and AI algorithm application methods and existing academic and technical data were reviewed to analyze and review application cases in similar fields. Through this, the goal was to develop an algorithm for determining the coagulant input rate and to present the optimal input rate through autonomous driving simulator and pilot operation of the coagulant input process. Through this study, the coagulant injection rate, which is an output variable, is determined based on various input variables, and it is developed to simulate the relationship pattern between the input variable and the output variable and apply the learned pattern to the decision-making pattern of water plant operating workers.
