  • Though the upper stream basin area of Gwanpyung-Cheon in Daejeon, Korea is protected as Green Belt Zone, the stream is under constant environmental pressure due to current agricultural practices and infrastructure development in its basin area. To develop appropriate integrated water resources management plan for the stream, it is necessary to consider not only water quality problems but also water quantity aspect. In this study, Storm Water Management Model (SWMM) was calibrated and validated with sets of field measurements to predict for future water flow and water quality conditions for any rainfall event. While flow modeling results showed good agreement by showing correlation coefficient is greater than 0.9, water quality modeling results showed relatively less accurate levels of agreements with correlation coefficient between 0.67 and 0.87. Hypothetical basin development scenarios were developed to compare effect on stream water quality and quantity when Low Impact Development (LID) technologies are applied in the basin. The results of this study can be used effectively in decision making processes of urban development Gwanpyung-Cheon area by comparing basin management alternatives such as LID methods.

  • This study, from a temporal standpoint, seeks to validate the relationship between prior shopping experience, a pre-experiential construct, and impulsive/planned purchase intentions, a post-experience construct, based on strategic experiential module advocated by Schmitt (1999) by focusing on three key variables--prior shopping experience, on-site experiences, and emotional response to store atmosphere. Also, from a spatial standpoint, the study aims to valiadate the relationship between emotional response to store atmosphere and impulsive purchase intentions across three retail store types--department store, discount store, and internet store. Specific research purposes and findings are as follows. First, it was found that regardless of the degree of prior shopping, discount store and internet shoppers preferred cognitive shopping experience to emotional experience. Second, emotional shopping experience significantly influenced impulsive purchase intention, whereas cognitive shopping experience influenced planned purchase intention. Third, for discount store shoppers only did the interior colour serve as a positive moderator between emotional shopping experience and impulsive buying intention, while merchandise display served as a negative moderator.

  • The source of a business competition is man and the core of a business success depends on people's ability, efforts and cooperation. Therefore, modern managers are making varied efforts to perform the ethical management for the organization immersion and job satisfaction of the employees. The managers of the financial agencies including the enterprises competing in the global market, face numerous ethical issues and problems. Considering the reality that financial institutions are actively asked to perform the responsibility and duties sincerely, the tasks how the head of financial agency will accept the social study of the level of ethics and change the level of recognition, and how he will settle it as the natural feature in the institution, become an important management target. In addition, it is necessary to figure out how the ethical management of the head of the financial agency will affect the organizational immersion of the employees. Based on the objective of this study, we attempted to confirm how the ethical management will of the head of the financial institution would affect the organizational immersion, the employees' mental result variables. Through this study, it became necessary for the directors of the financial institutions to search for the methods to improve the system of management and enhance the observance will of the business ethics so that they may not cause the disposition of the violation of the business ethics owing to the enforcement to achieve the target of the results of the business or the error recognition of the norm. Further, the heads of banks will have to set a management policy focused on the democratic management and the ethical justice based on the participating methods to induce the cooperative commitment of the stock company employees not to be shifted from the globalization and the competitive society.

  • The Working Unit of Forestry Management Cooperatives has been organized by the training and extention service center since 1984 so as to take charge of forestry work of Forestry Management Cooperatives, and this study has been carried out in order to find the problem of Working Unit of Forestry Management Cooperatives, and to show how to solve it in the future. We analyzed a material gained by the immediate questionnaires to 33 members of 4 Working Unit of Forestry Management Cooperatives in Ulsan-Kun, and 10 members of Working Unit of Forestry Management Cooperatives in Jinan-Kun between July and August in 1993. Later, we found that there was an almost inactive Working Unit caused by the insufficient work amount, which resulted in inefficient skill and forestry work due to leave of the skilled forestry worker. Though the government concentrates on bringing up the Working Unit centered by the specialized laborer, it is concluded that bringing up the Working Unit should consider local labor market, organization of agriculture and forestry, organization of labor, level of wage, and the amount of forestry work.

  • 본 연구는 참우드풀과 우드풀의 중간형으로 알려진 좀우드풀(Woodsia intermedia Tagawa)의 전엽체 증식 및 포자체 형성을 위한 기내 외 번식조건을 구명하고자 수행되었다. 실험재료는 포자를 발아시켜 획득한 전엽체를 8주 간격으로 계대배양하면서 확보하였다. 전엽체 증식에 적합한 배양조건을 탐색하고자, 전엽체 300mg을 다진 후 배지종류(Knop, 1/4, 1/2 및 1MS)와 배지구성물질(sucrose와 활성탄)의 농도를 달리하여 8주간 배양하였다. 배양실은 온도 $25{\pm}1.0^{\circ}C$와 광도 $30{\pm}1.0{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$(16/8h)로 조절되었다. 연구결과, Knop배지에서 생체중이 2.4g으로 전엽체의 증식이 가장 왕성하였다. 한편 MS계열 배지는 농도에 관계없이 매우 저조한 증식을 보였다. Sucrose는 0.5%를 첨가한 배지에서 생체중의 증가량이 가장 컸으며, 활성탄은 첨가농도에 관계없이 유사한 증식수준을 나타냈다. 포자체 형성에 적합한 토양조건을 확인하고자, 인공토양(원예상토, 피트모스, 펄라이트 및 마사토)의 비율을 달리하여 5종류의 혼합토양을 조성하였다. 혼합토양을 사각분($7.5{\times}7.5{\times}7.5cm$)에 충진하고, 준비된 전엽체 1g을 10초간 분쇄한 다음 토양표면에 분주하여 11주간 재배하였다. 재배환경은 온도 $25{\pm}1.0^{\circ}C$, 광도 $43{\pm}2.0{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$(16/8h) 및 습도 $72{\pm}2.0%$로 조절되었다. 연구결과, 모든 처리구에서 포자체의 형성이 확인되었으며, 특히 원예상토와 마사토를 2:1(v:v)로 혼합한 토양에서 포트당 421.0개의 많은 포자체가 형성되었다. 다음으로 원예상토와 펄라이트를 2:1(v:v)로 혼용한 토양, 원예상토, 피트모스, 마사토를 1:1:1(v:v:v)로 혼합한 토양, 원예상토 단용, 원예상토, 피트모스, 펄라이트를 1:1:1(v:v:v)로 혼합한 토양 순으로 각 228.0, 203.3, 126.8, 91.5개 형성되었다. 따라서 좀우드풀의 포자체를 대량으로 생산하기 위해서는 원예상토와 마사토를 2:1(v:v)로 혼용한 토양에 전엽체를 분주하여 재배하는 방법이 효과적일 것으로 판단된다.

  • In the 21st yearly session of the Conference of the Parties (COP 21) of the 2015 United Nations Climate Change Conference, held in Paris, France, in December 2015, the "Paris Agreement" was negotiated; this is a new global agreement on the reduction of climate change, which encourages every country to participate in countermeasures for global climate change. Along with such movements, the electric railway sector has also been actively engaged in low carbon technology. This paper studied the building of a 1.5MW photovoltaic power generation system using the rooftop of the Gwangmyeong Station Building, which is the largest roof among the high-speed railway station buildings in Korea; this station has passenger traffic that reached about 7 million in 2014. For this study, we configured an optimized photovoltaic (PV) power generation system and then estimated the expected annual energy production by using PV system software; we also calculated the expected revenue that could be obtained by linking this source to the power distribution system. The obtained data were used to analyze the contribution of low-carbon energy that could be obtained by introducing a PV power generation system on the roof of an electric railway station building.

  • Korean government has promoted the projects of National Geographic Information Systems since 1995 and the utilization level of Korean National Spatial Data Infrastructure based on them has also developed. However, due to the limit to domestic market size and the legal regulation on prohibition of large sized companies' expansion into domestic spatial information markets, Korean spatial information markets are tied up in term of industrial competitiveness. To overcome those problems and evade the domestic red oceans, it is necessary to find new one in overseas' blue ocean markets. It is estimated that overseas spatial information market will be grown to 125 billion-dollar size and the annual growth rate of it will be reached to 10.5% until 2015. Thus, Asian spatial information market has a huge growth potential and it is newly rising blue oceans for Korea. Advanced countries such as Finland, Germany, Sweden, and Japan have already expanded their market size into the newly industrializing countries. To step with advanced countries, it is time to set up the new globalization strategy of Korean spatial information for expansion into newly industrializing markets. The purpose of this study is to analyze the SWOT of domestic spatial information, investigate the status on spatial information of Asian developing countries, and suggest the globalization strategy of Korean spatial information for expansion into them. The globalization strategy can be labelled as K-FBI composed of 4 domains such as Knowledge sharing platform, Frontier, Back to the basic, and Internalization. In near future, the establishment and performance of road map based on the strategy will be the milestone for Korean spatial information companies' advance into Asian developing countries.

  • Olive flounder (Paralichthys olivaceus) is one of the most popular farmed fish in Korea. Genetic variability of the fish was investigated by means of microsatellite DNA markers. All of the 8 microsatellite loci were analyzed in this study. For the confirmation of genetic variation during a shift in generation, microsatellite variability was compared within the same hatchery strains but produced in different spawning years. When genetic variability of farmed flounders produced in 2006 and 2007 was compared with that of 2003, a marked reduction of genetic variability was observed in the 2006 and 2007 populations. Mean number of alleles per locus and expected mean heterozygosity decreased from 9.75 and 0.796 (in 2003 population) to 7.78 and 0.785 (in 2006 population), respectively. Moreover, we have observed the distortion of allele frequency. These results show that reduced genetic variability of farmed olive flounder in processed generation has lower numbers of alleles and genetic variability than these of wild fish. Our results suggest that to have a sustainable aquaculture of this species, there is need for scientific broodstock management based on genetic variation and more intensive breeding practices to improve genetic diversity and to avoid detrimental inbreeding effects.

  • The present study investigated the relationship between parental problem drinking and risk for malajustment in adolescents. A group of adolescent children of problem drinkers(126 boys, 210 girls) and a group of children of non-problem drinkers(190 boys, 222 girls) were compared on demographic variables, perceived relationships with parents(parental care and parental over-protection), depression, anxiety, alcohol expectancies, alcohol involvement and self-reported delinquency. Adolescent children of problem drinkers reported lower level of perceived parental care and higher level of perceived parental overprotection compared to the children of nonproblem drinkers. They also reported higher depression, anxiety and alcohol expectancies, as well as more alcohol involvement and delinquent behaviors. Multiple regression analyses were performed seperately for male and female adolescents with depression, anxiety, alcohol expectancies, alcohol involvement and self-reported delinquency as outcome variables. Adolescents' emotional distress(depression and anxiety) was associated with perceived relationships with parents rather than parental problem drinking, but adolescents' alcohol problems and delinquency were associated with parental problem drinking and adolescents' emotional distress rather than their perceived relationships with parents.
