In this paper, impervious area ratios for 11 land cover types of Seoul city were estimated and corresponding CNs were calculated. And linear regression equations were derived to predict impervious area ratios based on five major urban land cover types including the residential, industrial, transportation, commercial, and commercial-residential mixed areas. From the comparative analysis of impervious area ratios for the US SCS CNs and the CNs derived in this study for Seoul city, it is revealed that residential areas show the biggest difference followed by industrial and commercial ones. And in turn, these increased impervious area ratios resulted in Increased CNs for Seoul city including increases by 13 for residential, 12 for industrial and 5 for commercial areas. Therefore, it is suggested that applying the US SCS CNs to Korean urbanized areas may underestimate the flood runoff potential.

For the assessment of representative and longitudinal Zn nutriture in South Koreans, Zn, phytate and Ca intakes were determined using four consecutive years of food consumption data taken from Korean National Nutrition Survey Report (KNNSR) every 10 years during 1969-1998. The nutrient intake data are presented for large city and rural areas. Zn intake of South Koreans in both large city and rural areas was low during 1969-1988 having values between 4.5-5.6 mg/d, after then increased to 7.4 (91% Estimated Average Requirements for Koreans, EAR = 8.1 mg/d) and 6.7 mg/d (74% EAR) in 1998 in large city and rural areas, respectively. In 1968, Zn intake was unexpectedly higher in rural areas due to higher grain consumption, but since then until 1988 Zn intake was decreased and increased back in 1998. Food sources for Zn have shifted from plants to a variety of animal products. Phytate intake of South Koreans during 1969-1978 was high mainly due to the consumption of grains and soy products which are major phytate sources, but decreased in 1998. The molar ratios of phytate:Zn and millimmolar ratio of phytate${\times}$Ca:Zn were decreased due to the decreased phytate intake in South Koreans, which implies higher zinc bioavailability. The study results suggest that Zn nutriture has improved by increased dietary Zn intakes and the decreased molar ratio of phytate:Zn in South Koreans in both large city and rural areas.

Trade areas of the commercial centers in Chongiu City are rapidly changing as the urban spacial structure is transformed, consumer behaviors are changed and large shopping stores are located in the area. The City's CBD has been in the Sung-an-gil district. The trade areas of the CBD have expanded along the major roads in the directions of north, south and west from the Sang-dang park. Especially, two newly formed secondary commercial centers are noticeable: one is the center around the express bus terminal in Gagyong-dong, and the other is formed in the Yongam, Bunpyong and Sannam district. As such changes are intensified, small retailers in the traditional markets that are mainly concentrated in the Yukgerri market place have faced hardship in business and management. The commercial hardship has been hastened up by openings of large discount stores and expanding tendency of internet shopping businesses. Acknowledging the changes in the business environment of traditional markets, this paper attempts to suggest policies to gentrificate the declining market areas in the CBD. The suggested polices are differentiated according to the types of traditional markets, stores. and merchants. And also suggestion is provided regarding amendments of the City's codes.

The university admission system for talented students in computer and information areas has been mainly implemented during early admission period centering on universities located in metropolitan area since 1997. However, the current trend is that total number of selected students and universities that are selecting are continuously declining and 14 students were selected from 2 universities in school year 2013. Accordingly, it is difficult to expect positive effects on education related to information on secondary school curriculum, as well as train and select very talented students in certain areas. Such phenomenon is a result of insufficient educational activities on information of secondary school curriculum, as well as a reflection of social perception in the areas of computer and information. It shows that major variable with significant effects of university admission system has not been properly considered in the policy of training talented students at national level and the administration of secondary school curriculum on computer and information areas. Accordingly, there is a need for a comprehensive approach that considers the method and standards of universities' student selection system when establishing related future policy.

The purpose of this study is to identify influencing factors for successful introduction, implementation and management of HMRPS through assessment of the employees attitude toward HMRPS in technical, administrative, and organization behavioral areas. Data were collected from 157 HMRPS employee members' self-reporting questionnaire in three university hospitals in the city of Seoul and Kyonggi Province from November 5 to November 10, 1997. Relevant literature on industry company MPR system theory was reviewed to develop the theoretical framework. The results were as follows: The employee's recognition of tangible benefit were more significantly influenced success than intangible benefit for successful operation relating the HMRPS. Concerning the employee's recognition of the successful HMRPS and the factor of influenced success was significantly positive correlation between tangible and intangible benefits and success factor in technical, administrative, and organizational behavior area. This study showed that major factor affecting the employee's recognition of tangible and intangible benefit for successful HMRPS. For tangible benefits; Success factors in the technical areas were quality of the data and information, efficiency of inventory management and rescheduling of operation plan. Success factors in the administrative areas were: role of top management. Success factors in the organization behavioral areas were; simplicity of the HMRPS, human resistance to change. For intangible benefits; Success factors in the organization behavioral areas were; user involvement, simplicity of HMRPS, human resistance to change. Futhermore as the exact evaluation of successful factors of HMRPS implement is needed, research for the development of systemic variables of physical distribution system control, methods, capacity of system, duration and other environment in many of 30 hospitals or more, and for the empirical study for HMRPS.

Coastal sand dune area is the important ecosystem as an ecotone which located between coastal area and terrestrial area. Moreover, it is very complicate landscape that have geomorphological interaction between erosion and accumulation of sand. Therefore, it is necessary to understand the sand dune ecosystem in view point of landscape scale including background landscape affecting origin of sand dune. Landscape ecological approach in the complicate ecosystem already started in developed countries, and it is applied to land management and biodiversity conservation strategies even in national scale. In this paper, landscape ecological analysis using landscape pattern analysis was carried out on 7 study areas (Yellow Sea : Hakampo and Doksan, South Sea : Namyeol and Balpo, East Sea : Hosan, Hupo and Goraebul) in Korean coastal sand dune ecosystem. Landscape elements were composed by 9 elements in these study areas. Major background landscape elements was the forest land and agricultural field. Namyeol (S06) has larger patch landscape compare to other areas. In patch shape indices, Hupo (E10) shows more complicate patch shapes. The high landscape heterogeneity showed in the Doksan sand dune area and that of Hosan. It shows that these areas were composed by various patch types. However, using landscape indices have to use very carefully because several variables have influence to the result such as scale and spatial pattern of study areas. Although landscape analysis through landscape indices shows sometimes difficult to explain the ecosystem, landscape scale approach on ecosystem assessment still useful to interpret in ecological process in large range of habitat.

This paper aims to consider and draw policy implications for industrial crisis areas in advanced European countries with extensive experience in implementing regional industrial policies for regions facing industrial and employment crises due to deindustrialization, the decline of main industries, and industrial restructuring. In Europe, the paradigm and focus of support policies for industrial crisis areas have varied from time to time and from country to country. In particular, since the 2008 global economic crisis, it has again become a major issue of regional policy. Europe's recent policies for industrial crisis areas are characterized by a new model of development, with its focus on regional economic growth and job creation, and in the form of multifaceted and comprehensive regional policies through policy mix that combines regional development policies, industrial policies and employment policies.

For agricultural water management, it is essential to establish the digital infrastructure data such as agricultural watershed, irrigated area and canal network in rural areas. Approximately 70,000 irrigation facilities in agricultural watershed, including reservoirs, pumping and draining stations, weirs, and tube wells have been installed in South Korea to enable the efficient management of agricultural water. The total length of irrigation and drainage canal network, important components of agricultural water supply, is 184,000 km. Major problem faced by irrigation facilities management is that these facilities are spread over an irrigated area at a low density and are difficult to access. In addition, the management of irrigation facilities suffers from missing or errors of spatial information and acquisition of limited range of data through direct survey. Therefore, it is necessary to establish and redefine accurate identification of irrigated areas and canal network using up-to-date high resolution images. In this study, previous existing data such as RIMS (Rural Infrastructure Management System), smart farm map, and land cover map were used to redefine irrigated area and canal network based on appropriate image data using satellite imagery, aerial imagery, and drone imagery. The results of the building the digital infrastructure in rural areas are expected to be utilized for efficient water allocation and planning, such as identifying areas of water shortage and monitoring spatiotemporal distribution of water supply by irrigated areas and irrigation canal network.
