The characteristics of nonpoint source pollutant loads in upstream of Nakdong River were studied through analysis of pollutant loads of 10 sub-watersheds divided based on administrative district. The discharge and pollutant concentration of each sub-watershed were collected from Nakdong-River Water Research Institute and Daegu Regional Environmental office, respectively. Pollution items analysed in this study were BOD, T-N and T-P. The delivery loads of the nonpoint source pollutions of each sub-watershed were calculated after analysing the concentration of the pollution of each site. Several points were found from the results. Firstly, in general, city areas including Sangju, Andong showed higher degree of nonpoint pollution than country areas including Cheongsong, Yeongyang. The sub-watersheds located upstream side, such as Yeongju, Bonghwa, Necessarily show better water quality than the sub-watersheds located downstream side, such as Mungyeong, Uiseong. This result indicates that a given pollution condition within the watershed can be more sensitive than location factor to the level of water quality. Secondly, the delivery load and area of watershed were not necessarily correlated in the sense of water quality, while the discharge was shown to be highly correlated to the delively load of pollution. Lastly, sewage and waste caused from population and livestock, as well as landuse factor, were found to significantly contribute to the water pollution. Alternative solutions for controlling pollution source, therefore, should be provided to meet target levels of water quality in these regions.

Air pollution has attracted ever-increasing attention because of its substantial influence on air quality and human health. To better understand the characteristics of long-range transported pollution, the single particle chemical composition and size were investigated by the single particle aerosol mass spectrometry in Fuzhou, China from 17th to 22nd January, 2016. The results showed that the haze was mainly caused by the transport of cold air mass under higher wind speed (10 m·s^-1) from the Yangtze River Delta region to Fuzhou. The number concentration elevated from 1,000 to 4,500 #·h^-1, and the composition of mobile source and secondary aerosol increased from 24.3% to 30.9% and from 16.0% to 22.5%, respectively. Then, the haze was eliminated by the clean air mass from the sea as indicated by a sharp decrease of particle number concentration from 4,500 to 1,000 #·h^-1. The composition of secondary aerosol and mobile sources decreased from 29.3% to 23.5% and from 30.9% to 23.1%, respectively. The particles with the size ranging from 0.5 to 1.5 ㎛ were mainly in the accumulation mode. The stationary source, mobile source, and secondary aerosol contributed to over 70% of the potential sources. These results will help to understand the physical and chemical characteristics of long- range transported pollutants.

As the functions and roles of public libraries expand, it is time for qualitative growth. In order to improve the quality of public libraries, it is important to plan actual construction costs through systematic feasibility study. Therefore, the purpose of this study is to present the guideline of construction costs considering the size and regional characteristics according to the status role of the new public libraries. The construction costs are based on actual data. The results of the study are as follows. First, we derived the analysis framework according to the size and regional characteristics. The status role of the public libraries was considered theoretically. The size was classified according to status role of the public libraries. Regional characteristics were classified through literature review. Through this, an analysis framework was derived according to size and region. Second, the actual data on construction costs of the new public libraries were examined and analyzed. Basic factors, size, area, and construction costs were analyzed for 285 libraries nationwide that opened from 2010 to 2016. The data of 129 newly opened public libraries were classified. To present construction costs depending on price fluctuation, construction cost index was analyzed as of September 2016. Third, a guideline of construction costs for new public libraries was suggested. The construction cost per $1m^2$ of building area was analyzed. By multiplying 116.70(p), the construction cost index, the construction cost per $1m^2$ of total building area was calculated to be 2,472,350 won. When applying the research result, construction costs can be gained by adding construction cost index of the month.

The purpose of this study is to explore and compare the regional characteristics of textile industries and corresponding education systems in Korea and Italy. The Italian textile industry is well known for its continuous development of high quality textile fabrics and aesthetic fashion design. One of contributing factors for the success of Italian textile industry is its regional specialization of the industry and corresponding education systems. In particular, the regional education systems in Italy are designed to educate and supply labors necessary to the development of the regional textile industries. According to the study, this characteristic is well shown in their curriculum which emphasizes the practicality and corporation with the industry. In contrast, the Korean education system for the textile industry ignores the regional specialization and its curriculum is designed, in large part, to produce textile designers. This causes difficulties in meeting the various demands from the industry such as the textile planning, textile production, and textile marketing and sales. To solve the problems, we must encourage the industrial-educational corporation to promote the practicality of the textile education system and make diversification and specialization of the curriculum of textile education to cultivate men of talent, such as merchandisers, fashion coordinators, converters, stylists, and displayer, necessary to the development of the Korean textile industry.

Purpose - This study analyzed the determinants of local unemployment rate in Korea using panel data from 16 metropolitan cities and provinces from 2000 to 2018. Design/methodology/approach - We use a dynamic spatial panel model that considers characteristics of the regional unemployment rate such as the common factors effect, spatial dependence, and serial correlations. Findings - The local unemployment rate is affected by the past and present values of the national unemployment rate. And it is significantly affected by the past local unemployment rate and the past neighboring unemployment rate because spatial dependence and serial correlations are clearly present. In addition, when the industrial structure diversity and labor productivity were high, the regional unemployment rate decreased, and when the education level was high, the regional unemployment rate increased. Research implications or Originality - In order to reduce regional unemployment rate, it is necessary to plan and establish regional customized industrial structure policies under the stance of diversification rather than specializing the regional industrial structure and accompany improvement of the quality of education with the number of years of education. In addition, the redistribution of labor from low labor productivity sectors to high labor productivity sectors through technology development will help to reduce the local unemployment rate.

Surface soil is one of the most important resources that have many functions for human needs such as conservation of water resource, purification of contaminated materials, and productivity of food or energy. However, the surface soil is a limited resource that cannot be recovered readily for a long time once it is lost by erosion. In Korea, the Ministry of Environment enacted the notification on the investigation of surface soil erosion and corresponding countermeasures. As the results, database of soil quality assess criteria (biomass, groundwater recharge, habitat, carbon storage, buffer, and soil loss) was established, and the web-based system that can evaluate surface soil conditions was developed. However, non-experts have difficulties in using the system because the system requires in-depth knowledge about soil qualities. In this study, the Web Geographic Information System (GIS) watershed-based surface soil information system was developed to improve usability of the system and accessibility of soil quaility database. The system provides the current condition of surface soil characteristics and GIS-based soil data at selected locations. The users are able to download soil quality data in different districts, watersheds, and special regions allocated by TauDEM module. The system developed in this study would valuable surface soil information for studies of soil quality and its environmental effects, and thereby contributing to establishing more appropriate and robust soil conservation laws.

To improve the standardized quality of gochujang produced by major companies, the quality characteristics of 29 gochujang samples produced by regional small- and medium-scale manufacturers were determined. The average moisture content, crude protein content, pH, acidity, and salinity of gochujang from regional manufacturers were found to be 34.32-45.53%, 5.07-5.68%, 4.61-4.92, 3.30-3.72%, and 9.93-16.14%, respectively. The contents of reducing sugar, amino type N, and capsaicinoids were found to be 16.81-29.81%, 191.72-660.55 mg%, and 32.49-79.58 mg/kg, respectively, and the ${\alpha}$- and ${\beta}$-amylase activity were 2.52-4.15 and 26.36-36.47 U/g, respectively. These values varied significantly across regional manufacturers. In addition, overall, gochujang had a range of 23.93-55.64% moisture content, 4.01-7.30% crude protein content, 105.47-1092.00 mg% amino type N content, and 8.74-181.50 mg/kg capsaicinoid content. These results indicate that the quality characteristics of gochujang showed a wide distribution but met the Korean Industrial Standards. Therefore, these data can be used for quality control of gochujang.

This study is conducted to investigate the current status on the utilization of health care and plan for solving this problem. The claims data of the fiscal tear 1995 obtained from the regional health insurance society are used for the study. The main findings of the study are summarized as follows. Indexes(The Extremal Quotient(EQ), coefficients of variance(CV's))which represent the regional difference in the admission rate of the tertiary medical diagnosis group report that there is difference in quantity and quality of utilization of health care. The admission rate is lower in the big city areas, Kyoungkido, Kangwondo and Chunlapukdo. Even after age-sex adjustment, the admission rate is still low in Kangwondo, Chunlapukdo and Kyoungsangpukdo. The big city areas tend to have higher rates in the expenses per claim, hospital days per claim, and daily expenses but the rates are still low in some area in Kangwondo, Chunlanamdo and Kyoungsangpukdo. This result remains as same after age-sex adjustment. There is a large regional difference in average utilization rate for the tertiary hospital of the tertiary medical diagnosis group: 57.2%(SD 11.53). The utilization rates for the tertiary hospital in their large catchment area are 96.34%, 83.19% and 73.22% in each Kyoungin, Kyoungnam and Kyoungpuk areas whereas it is lower in a Chungpuk and Chungnam areas. The regional differences of health care utilization of the tertiary medical diagnosis group gave some relationships with their geographical characteristics such as socio-economic characteristics and supply factors of medical services. It is important that many medical policies should be developed in order to minimize and balance out the regional differences of health care utilization. The service allocation policy should include the reconstruction of manpower policy, developing the resource allocating formula, finding the self-sufficient catchment area and reforcing of public health services. Moreover, in order to achieve the balanced development by region, they should investigate and consider each county's microscopic properties under the consistent macrocopic policy. The further studies to find causes of regional difference are needed.
