The water status of the leaves of several evergreen plants was investigated in order to discuss the geopgraphical distribution of them. Relastionship between relative water content and water potential of the leaves showed linear decrease for evergreen conifers but exponential decrease for Korean box tree (Buxus microphylla var. koreana). On the basis of the leaf water potential, the water status of the conifers during wintering was distinctly divided into three periods; hardening, cold resistance and dehardening, but lacking in those periods for the Korean box tree, where the status continously decreased. In the cold resistance the leaf water potentials were -23 bar for both spruce (Picea jezoensis) and yew (Taxus cuspidata). From these results and threshold temperature at beginning of hardening, distribution of the conifers was explained that in order of the red pine, the Korean white pine, the yew and the spruce the distribution could be extended at higher altitudes and in more northward areas, whereas the distribution of the Korean box tree was restricted to the lowland of temperate zone.

The purpose of this study carried out to analyze production status, pricing trend and distribution status of landscape plants, so that it could predict the demand of landscape plants for the balance of supply and demand. The production amount of landscape plants made constantly increased. The annual output of shrubs increased more higher than that of trees. The prices of trees have raised consistently, but shrubs were susceptible to price fluctuations. And there were still many problems in the distribution structure. The landscaping work has focused on the metropolitan area. And large-scale nationwide projects were scheduled for coming years, so the demand of landscape plants was expected to expend. However, the lack of increase in production amounts of landscape plants, it is cause to supply problems. So, demand forecast was necessary to control the production of landscape plants.

The purposes of this study are as follows. First, it is to review the features of discount stores that are expected to grow rapidly and continuously due to their low price, low cost, bulk purchase, and multiple shops, and to pinpoint problems arising from the establishment and position of the stores. Second, it is to analyze relevant issues in regard to the present status of fashion good distribution in discount stores by studying the situation, structure and problems of domestic fashion distribution along with the present status of the distribution in discount stores, and to suggest directions for the development of fashion distribution and discount stores. A positive study was carried out on the buyers of big domestic discount stores through one-to-one interviews focusing on the distribution of fashion products within Seoul and the Metropolitan area. The following is the directions for the development of clothing distribution and discount stores ; 1. The relative importance of fashion goods in a discount store will be increased with the tendency of fashionable and differentiated shops ; 2. The GMS or category killers will be established from around 2003 when the market is expected to become saturated with a great deal of discount stores. 4. Discount stores will change and reform without being restricted to a certain existing industry or business condition, and distribution channels will diversify over the border. The demand and supply system will be balanced based on a global marketing which will be adjusted on the international level.

우리나라에 서식하는 파충류상과 분포 현황을 파악하기 위해 제2차 전국자연환경조사, 국립공원자연자원조사, 개인 조사결과 등이 분석되었다. 그 결과 우리나라에 서식하는 파충류는 총 2목 7과 21종으로 확인되었다(장수거북, 바다거북, 붉은바다거북, 바다뱀, 얼룩바다뱀, 먹대가리바다뱀 등 해양 파충류 제외). 또한 분류학적으로 많은 논쟁이 있는 도마뱀류, 장지뱀류, 뱀류에 대한 분류학적 고찰이 시도되었다. 그러나 추가적으로 해양파충류에 대한 연구가 필요할 것을 판단된다.

Kimchi cabbage is one of the most important vegetables in Korea and a target crop for market stabilization as well. In particular Kimchi cabbages in a highland area are very sensitive to the fluctuations in supply and demand. Yield variability due to growth conditions dictates the market fluctuations of Kimchi cabbage price. This study was carried out to understand the distribution of the highland Kimchi cabbage growth status in Anbandeok. Anbandeok area in Gangneung, Gangwon-do, Korea is one of the main producing districts of highland Kimchi cabbage. The highland Kimchi cabbage status map of each growth factor was obtained from unmanned aerial vehicle (UAV) imagery and field survey data. Six status maps include UAVRGB image map, normalized difference vegetation index (NDVI) distribution/anomaly map, Crop distribution map, Planting/Harvest distribution map, Growth parameter map and Growth disorder map. As a result, the highland Kimchi cabbage status maps from May 31 to Sep. 6 in 2016 were presented to show spatial variability in the field. The benefits of the highland Kimchi cabbage status map can be summarized as follows: crop growth monitoring, reference for field observations and survey, the relative comparison of the growth condition in field scale, evaluation of growth in comparison of average year, change detection of annual crops or planting areas, abandoned fields monitoring, prediction of harvest season etc.

In recent years, the photovoltaic(PV) industries have been increasing steadily above averaged $30\%$. Japan, USA and Europe have been playing a leading part in photovoltaic industry. In this paper, we review status of the global PV market and distribution around these countries. From the results, we will intend to supply the useful materials for domestic PV distribution.

The distribution companies in Korea usually specify the buying system in jikmeip, tukjeongmeip, imdeeul, and imdegap. In this view, the development of distribution companies in Korea is highly dependent on the which business status is emphasized. And it is considered critical to identify the important features of each buying system and the impact these systems have on each business status. Subsequently, the purpose of this study is to identify the said features and impact. With this study, we have tried to explore a new vision for distribution taking a consideration of the fact that most studies within Korea are oriented in marketing standpoint. Particularly, we have intended to analyze the distribution industry in the view of internal standpoint of a distribution company.

Purpose - This study investigated the development process of the Chinese distribution industry and analyzed the current status of China's offline and online distribution industries under the development process of the Chinese distribution industry. In addition, the current status of offline distributors in China and representative companies were analyzed as case studies. Research design, data, and methodology - This study analyzed the overall environment of the Chinese distribution industry by using literature data. Then, this study conducted a case analysis using RT Mart and Jingdong, major companies in the distribution industry. Result -The main research results of this study show that the Chinese distribution market has already matured, and retailers are fiercely competing to secure sales and operating profits through various methods such as finding new management methods, improving awareness and customer loyalty by expanding the number of stores. Conclusion -Recently, the characteristic of China's distribution industry is that the boundaries of distribution are breaking down. Chinese retailers are taking strategies to expand the scope of services by erasing the boundaries of distribution. In other words, distribution companies are promoting a borderless distribution strategy in which consumers purchase products online and offline without restrictions on time and space. In addition, small stores in residential areas are on the rise compared to large-scale stores in the city center. The existing distribution industry operates various types of distribution stores to prepare for the post-COVID-19 crisis.

This study has been conducted to propose an optimal design guidance of underfloor air distribution system by examining air pattern and proper exhaust status of floor plenum using CFD (Computational Fluid Dynamics). Simulation shows deficient air pattern and exhaust status at BPG (Bypass Grille) of the current design. As a means to find an alternative design, four cases have been developed and tested. Case 1, 2 and 3 show similar results in comparison to the current design. However, case 4 shows improved air pattern and exhaust status at BPG(Bypass Grille), and has been chosen as the optimal alternative.
