  • The location of auto industry in Jeon-buk is due to the strategies for secure a low-priced industrial site of the auto assembly companies, which attained to quantitative growth stage in the early part 1990's, and the regional balanced development policy by the location of leader enterprise of the government. As a consequence of the reversal development pattern that is located the auto parts firm after locating the auto assembly companies, the Jeon-buk auto industry has many structural vulnerability. First, because of the lack development of auto parts industries, the auto assembly companies located in Jeon-buk are dependent many auto parts at a external region. Second, most of auto parts firm belongs to the singular assembly company exclusively. And the majority of auto parts industries are the low value-added products that are necessary a simple labor power. Third, the agglomeration undeveloped of associated industries with automobile caused a low competitiveness of invitation a manufacturing company as against other provinces. For a regional economic development by the auto industry, it is necessary a flexible regional structure of production through an agglomeration of associated industries. The geographical proximity between an assembly company and a parts firms is an important locational factor with the induction of Just-in-Time production system and a modularization in the auto industry. And a modularization applies to more new factory than the existing factories. So that, Jeon-buk self-government has to create an amicable industrial environment, try to attract an auto parts enterprises and plan an agglomerated industrial complex that is able to supply a parts modulated to assembly company.

  • 현재 오염총량관리제를 시 군 단위의 기초자치 단체별로 시행하고 있는데 실제로 오염물질의 전달은 행정구역단위가 아닌 유역내에서 이루어지진다. 따라서 본 연구에서는 기초자치 단체별이 아닌 유역단위로 오염부하량과 삭감량을 산정함으로써 유역 단위의 오염총량관리제 계획 수립을 위한 토대를 제공하고자 한다. 본 연구에서는 보청천 유역을 대상으로 유역의 오염부하량을 산정하고자 하였다. 이를 위하여 지리정보시스템(GIS)인 WMS(Watershed Management System)와 ArcView를 이용하여 유역의 지형인자들을 추출하고, 각 소하천의 토지이용도와 생활계, 축산계, 양식계, 토지계를 바탕으로 원단위를 적용하여 발생부하량을 산정하였다. 그리고 각 소하천별 발생부하량 산정 결과를 토대로 각 수질관측점을 기준으로 하여 배출부하량을 산정하였으며, 배출부하량의 산정결과를 이용하여 유달부하량을 산정하였다. 이를 위해서 필요한 수질 데이터는 QUAL2E 모형을 이용하여 모의 하였으며, 수리 및 수질 매개변수를 추정하고 모형의 보정 및 검증을 수행하였다. 그 결과 유달부하량은 BOD는 2013.16kg/일, TN은 1091.34kg/일, TP은 235.16kg/일이 도출되었다. 따라서 장래에 수질이 악화될 경우를 고려하여 수질 항목별 오염량이 2배, 3배로 증가한다고 가정하였다. 오염량이 2배 증가하였을 경우, 오염부하량을 산정한 결과 보청천3 지점에서 BOD는 184.68kg/일이 삭감되어야 하고, 오염량이 3배 증가하였을 경우 BOD는 1775.69kg/일이 삭감되어야 한다는 결과를 도출할 수 있었다. 본 연구와 같이 유역단위로 오염부하량을 산정할 경우, 오염원을 줄이는데 효율적일 것으로 생각되며, 향후 오염총량관리제를 위해 유역단위의 오염부하량 산정을 고려하면 좋을 것으로 사료된다.는 지배적인 요인으로 남게 될 것이다. 본 연구에서는 현재 진행중인 승기천 오염하천 정화사업이 종료되는 시점을 기준으로 남동유수지에 대해 승기천과 연계한 유수지의 환경개선 방법을 제안하였다. 준설을 통해 유수지의 근본적인 오염원을 제거하고 남동유수지 유입부에 인공습지와 수처리설비를 설치하여 유수지의 수질을 개선하고 개선된 수질이 3급수로 유지하도록 하였으며, 설치된 인공습지에는 철새도래지를 조성하여 유수지 유입수인 철새가 날아드는 하천인 승기천의 테마와 연계하도록 하였다. 인공습지 주변으로 식생호안을 설치하고 유수지 주변에는 산책로를 설치하여 지역주민들의 친환경 수변공간으로 활용하도록 하였다. 1유수지와 연결된 2유수지는 BTL사업을 통해 주변공단으로부터의 오폐수를 원천적으로 차단하도록 하였으며 2유수지를 매립하여 지하는 강우시 유출수 저류가 가능한 화물차주차장으로 활용하고 지상은 녹지공간으로 조성하여 공단근로자 및 지역주민을 위한 휴식공간으로 활용될 수 있도록 제안하였다. 본 연구는 남동유수지 환경 개선 사업 실행을 위한 정책 연구로 연구결과를 인천시가 적극 수용하기로 결정함에 따라 인천시의 환경 현안 문제인 남동유수지의 수질개선을 통해 시민의 휴식 및 여가선용 공간으로 활용하기 위한 사업의 기초자료로 활용되며 이미 설계검토가 시작되었다. 본 연구결과는 유수지 및 저수지의 환경개선 사업의 선두적인 성공사례로 국내 타 지역의 유사한 사업에 있어 벤치마킹을 할 수 있는 훌륭한 사례가 될 것이다.요 생산이 증가하자 군신의 변별(辨別)과 사치를 이유로 강력하게 규제하여 백자의 확대와 발전에 걸림돌이 되었다. 둘째, 동기(銅器)의 대체품으로 자기를 만들어 충당해야할 강제성 당위성 상실로 인한 자기수요 감소를 초래하였을 것으로 사료된다. 셋째, 경기도 광주에서 백자관요가 운영되었으므로 지방인 상주

  • Readability, an indicator measuring the easiness of reading letters, is an important element that determines the communicative effectiveness of self-guided signs. This study examined how the letter design elements of self-guided signs influence on readability to provide basic information for more effective sign designs. Data were collected from August to November of 2003 at a self-guided trail of Naejangsan National Park, Korea. A total of 375 subjects participated in the questionnaire survey, and 94.7% of them were used for data analysis. Among the total of 19 attributes, five attributes such as number of letters, number of type styles, ratio of picture area on the signs, space between letters, type size influenced on readability. These five attributes explained 50.0% of the variation in readability. The number of letters was the most influential attributes on readability, followed by the number of type styles, ratio of picture area on the signs, space between letters, and type size. The effectiveness of signs may be efficiently increased by managing these five major attributes with more concern.

  • Purpose: The purpose of this study was to investigate the family composition of terminally ill cancer patients admitted to the hospice unit and how it affects their hospice care. Methods: We retrospectively analyzed the medical records of terminal cancer patients who died in one hospice unit between January 2009 and March 2014. The demographic and clinical characteristics of the patients were examined, and any different made by their marital status was evaluated. We calculated the time interval between cancer diagnosis and hospice admission and the survival period from hospice admission to death and analyzed their association with family composition. Results: When divided by the median time of 13 months between diagnosis and admission, Group B (>13 months) had a significantly higher proportion of patients living with their spouses; (P<0.01). The main decision maker was a spouse (52.9%) in Group B; (P=0.04). Conclusion: Among the characteristics of the family composition, the presence of spouse was an important factor associated with admission to a hospice unit. Clinicians need to be aware of the impact of marital status on end-of-life care. This study indicates that it is helpful to understand family composition of terminallyill cancer patients for an effective palliative and hospice care.

  • Wind power has been rapidly growing over last decade in the world as well as in South Korea as a feasible renewable energy source. Providing sustainable energy to all while securing environmental sustainability requires evidence based policy making and innovative solutions. Through analysis of 58 cases of South Korean Environmental Impact Assessment (EIA) Report, this paper seeks to identify answers to the following two questions. What are the key characteristics for inland windfarm? Is there a way of measuring environmental sustainability to compare each location to reduce negative environmental impact? Variables related to environmental sustainability of each windfarm case were collected from EIA report and the factor analysis of environmental variables was conducted to calculate the weight for each variable to build environmental sustainability index (ESI) to provide as evidence-based tools for decision making on the location of inland windfarm. 58 cases were categorized as three types 1) Mountain type 2) Ranch Type and 3) Coastal Type depending on their height and degree of naturalness. For analytical research, first, it was successfully calculated environmental sustainability of each windfarm case ranging from 1.04 (#33, Ranch type) to -1.44 (#55, Mountain type). Second, the analysis results showed that ranch type is most environmentally sustainable (Average ESI = 0.4551), followed by coastal type (Ave ESI = 0.3712) and lastly mountain type (Average ESI = -0.3457). These findings are consistent with the previous researches on inland windfarms and provides substantive policy implication on the renewable energy policies.

  • Recently, the increase of international trade volume is leading to risk exposure and safety accidents in the port terminal industry. In addition, as Serious Disaster Punishment Act came into effect on January, 2021, various guidelines and laws to protect safety and life in port terminals are being enacted. However, despite these efforts, medium-to-large safety accidents in the port terminal industry have occurred. According to the Korea Occupational Safety and Health Agency, from 2016 to 2019, the number of casualties in the port handling industry increased by 4.2%. To build some effective follow-up management of port accidents and preparation of related safety laws/systems, a risk analysis in consideration of causes and damage of accidents should be conducted. Therefore, in this study, major risk factors and preventive measures were derived by conducting risk assessment based on 1,039 cases of port terminal accidents collected by the Korea Occupational Safety and Health Agency for five years. Priorities for preventive measures were then determined through IPA analysis, Borich needs analysis, and The Locus For Focus analysis.

  • A discussion has recently emerged over the increase of approvals of K-REITs, which is concluded on the basis of how to raise funds for business activity, fulfill the expected rate of return and maximize the management of managing investment funds. In addition, corporations need to acknowledge the necessity of the capital structure reflected in the current economic environment and decision-making processes. This research analyzed the characteristics by investment types and influence factors about the debt ratio of K-REITs. The data were collected from general management about business state, investment, and finance from 2002 to 2015 in K-REITs (except for the GFC period of 2007~2009). The results of the research demonstrated the high ratios of the largest shareholder characteristics, which are corporation, pension funds, mutual funds, banks, securities, insurance, and, recently, the increasing ratio of the largest shareholder and major stockholder. The investment of K-REITs is increasing the role of institutional investors that take a leading development of K-REITs. The behaviors of simultaneous investment of institutional investors were analyzed to show that they received higher interest rates than other financial institutions and ran in parallel with attraction and compensation. The results of the multiple regressions analysis, utilizing variables about debt ratio were as follows. The debt ratio showed a negative (-) relation that profitability is increasing, which matches the pecking order theory and trade off theory. On the other hand, investment opportunities (growth potential) showed a negative (-) relation and assets scale that indicated a positive (+) relation. The research results are reflected as follows. K-REITs focused on private equity REITs more than public offering REITs, and in the case of financing the capital of others, loan capital is operated under the guarantee of tangible assets (most of real estate) more than financing of the stock market. Further, after the GFC, the capital of others was actively utilized in K-REITs business, and the debt ratio showed that the determinant factors by the ratio and characteristics of the largest shareholder and investment products.
