This study suggests that the system improvement priority of the Natural Conservation Zone of the Metropolitan Area Maintenance Planning Law, which was enacted for about 37 years. First of all, through the precedent research and the consultation meeting, the improvement plan was divided into the short term and the mid(or long) term. Important findings and implications are as follows. The short-term priority results were 'Improve water quality regulation', 'Strengthen individual location regulations of factories and induce multi-use plan position', and 'Improvement of waterfront area regulation', which were both critical and urgent. The mid-term(or Long-term) priority results were 'To integrate development and environmental duplication regulations', 'Abolition and unification of environmental laws', and 'Adjustment and resetting of natural conservation areas', which were both critical and urgent. On the other hand, 76.4% of the residents and 64.5% of the experts are concerned about the necessity of improvement of the Natural Conservation Zone system. Both residents and experts seem to be aware of the necessity. Opinions about Improvement and mitigation of regulations on Natural Conservation Zone that were constantly raised. In the past, there was a temporary and fragmented institutional mitigation of the government. However, with the rapid development of eco-friendly technologies since 2010, Our Country Conditions is in a transition period. This study has significant implications for the improvement and mitigation of metropolitan area regulations.

수요자 중심의 6차산업 특화단지 조성을 위한 탐색적 연구
이윤상,안현,Lee, Yun-Sang,Ahn, Hyeon 한국토지주택공사 토지주택연구원 2018 LHI journal of land, housing, and urban affairs Vol.9 No.2
Korea seems to have introduced the legal basis for supporting and revitalizing the 6th industry since about 2010. Problems such as lack of systematic support system, inadequacy of cooperation and cooperation between ministries, and poor efficiency have been raised. Also, there is a lack of information on the designation, development method, participant, and management plan of the 6th industrial complex. In this study, we review prior researches and cases related to the 6th industry and examine how to efficiently create the 6th industry-specific complex by analyzing the requirements of customers for the enterprises, residents, professionals and officials of the metropolitan area and non-metropolitan areas. As a result of the questionnaire survey, some suggestions for the establishment of the 6th industry specialization complex were drawn. First, 77.5% of the total requires a combination of public and mixed use, which can be expected to have positive effects such as sharing development gains with local residents and improving resettlement of local residents. Second, the 6th industrial complex should be harmonized with the 1st, 2nd and 3rd industries. However, unlike the standardized land use plan of existing industrial complex, it is necessary to expand the distribution and sales space to reflect the demand for tertiary industry. It is also necessary to consider measures for securing primary industrial sites or securing primary industrial sites through external procurement. Third, it is necessary to establish and operate a plan reflecting rent and rental demand after leasing for a certain period.

1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to research the practicality of the mixed developing method in land development system. (2) RESEARCH METHOD This study is focused on case-study analysis. The data for this analysis were collected from the actually developed site (Kimpo Kocheon). This study approached on the comparing with three developing methods through an application of the expropriation, the replotting and the mixed developing system in a site. (3) RESEARCH FINDINGS In the results of this profitability ratio, the mixed developing is 1.33, the expropriation is 1.27 and the replotting is 0. Of course, this is the result of a sample analysis. 2. RESULTS Interest regarding the mixed developing is recently increase through folllowing disadvantageous things such as the inhabitant migration of the expropriation and the privatization of developing profit of the replotting. This study offers two meaningful items of mixed developing system in land developing market. 1) In the respect of an operator, the mixed developing system can be insured the profit. 2) In the respect of a land owner, the mixed developing system can be also guranteed the developing gain.

기업의 사회책임 세부지수와 조세회피 관련성에 관한 연구
이윤상 ( Lee Yun-sang ) 한국세무회계학회 2018 세무회계연구 Vol.0 No.57
기업의 사회책임(CSR)활동은 외부적인 윤리행위로서 내부적인 비윤리행위인 조세회피와 밀접한 관련성을 가지고 있다. 본 논문은 선행연구를 확장하여 CSR성과의 대용치로 경제정의지수(KEJI) 총지수와 경제정의지수(KEJI) 세부 지수를 모두 사용하고, 조세회피의 측정치도 Desai and Dhalmapala(2006)에 의한 조세회피 측정치와 그 측정치의 절대값을 모두 사용하여 CSR과 조세회피의 관련성을 실증분석하였다. 실증연구를 위한 표본은 2011년부터 2016년까지 총 6개년에 걸쳐 경제정의지수(KEJI) 평가기업 중 기타 재무자료가 이용 가능한 1,730개 기업을 대상으로 하였다. 검증결과는 첫째, CSR 전체 지수와 조세회피는 음의 관련성을 나타내었으며, CSR세부 지수와 조세회피와의 관련성의 경우 건전성지수와 사회공헌도지수가 조세회피와 유의한 음의 관련성을 나타내었다. 종속변수로서 조세회피의 절대값을 사용한 경우, CSR 전체지수와 조세회피의 절대값은 유의한 관련성을 나타내지 못하였다. CSR세부 지수와 조세회피와의 관련성은 공정성지수의 경우만 조세회피의 절대값과 유의한 음의 관련성을 나타내었다. 둘째, 추가분석으로, 조세회피가 0이상인 경우 CSR 전체지수와 조세회피는 유의한 음의 관련성을 나타내었고 CSR세부 지수와 조세회피와의 관련성을 살펴본 결과 사회공헌도지수의 경우만 조세회피와 유의한 음의 관련성을 나타내었다. 조세회피가 0이하인 경우는 CSR전체지수와 조세회피는 CSR전체 지수가 높을수록 조세회피가 줄어드는 결과를 보여주었고 CSR세부 지수와 조세회피의 관련성은 건전성지수와 사회공헌도지수의 경우 조세회피와 유의한 음의 관련성을 나타내었다. Corporate social responsibility(CSR) activities are external ethical behaviors and are closely related to tax avoidance, which is an internal unethical act. In this paper, we use both the KEJI total index and the KEJI sub - index as a CSR outcome for empirical analysis. Also, Desai and Dharmapala(2006)’ tax avoidance measure and the absolute value of tax avoidance are both used for empirical analysis. The results of this study are as follows:First, negative relation between CSR total index and tax avoidance is shown. In the case of relation between CSR detailed index and tax avoidance, negative relation with soundness index and social contribution index Respectively. When the absolute value of tax avoidance was used as a dependent variable, the CSR total index and the tax avoidance absolute value were not significant. The relationship between CSR detailed index and tax avoidance showed a significant negative relationship only in the case of fairness index. Second, when the tax avoidance is 0 or more, CSR total index and tax avoidance showed significant negative correlation. As a result of examining the relationship between CSR detailed performance and tax avoidance, only the social contribution index showed significant negative correlation with tax avoidance. When the tax avoidance is less than 0, the result show that the higher the CSR total index, the less tax avoidance. The relationship between fairness index and social contribution index showed significant negative correlation with tax avoidance when we examined the relationship between CSR detailed performance and tax avoidance.
