  • The ${\Delta}^5$ sterols were measured in be sediments of Jinhae Bay surrounded by industrial cities to assess the sewage-derived contamination. The total concentrations of total sterols ranged from 2.03 to 19.56 ${\mu}g/g$ dry wt. The principal sterol was cholesterol with a contribution of more than 50% to total sterols. Coprostanol, providing an indication of long-term sewage loads, was found in all sediment samples and the concentrations were 0.03-3.86 ${\mu}g/g$ dry wt, accounting for 1-26% to total sterols. The cluster analysis of sampling stations indicated that the sewage-derived contamination was localized in inner Masan Bay.

  • The current study was carried out to determine the influence of different resting surfaces and stall types on milk yield and animal health. Study was carried out in Bursa that is one of the most important cities of Turkey in terms of dairy production. Effects of resting surfaces and stall types on milk yield were found to be important. Also influence of different resting surfaces and stall types on lactation length was examined and found that rubber mats were different from the two other options. Relationships between different resting surfaces or stall types and health problems were examined and connection between stall type and repeat breeding (RB), dystocia, retained placenta and a connection between resting surface types and RB and clinical mastitis were found to be important. Considering their economic reflections, it can be said that results are quite important to the Turkish dairy industry.

  • Purpose: This study was designed to identify the self concept and clinical competency of nurses in hospitals and to examine the relationship between two concepts. Methods: A questionnaire was used for data collection which was done from July 1 to July 30 in 2005. The respondents were 267 staff nurses in a university hospital and general hospitals in two cities. The instruments were Son's(2002) self concept scale and Lee's(2002) clinical competency scale. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression using SPSS-WIN. Results: The results of this study were summarized as follows: First, the total mean score of self concept was 2.56, and clinical competency was 2.59 on a 4 point scale. Second, the self concept and clinical competency were significantly correlated. Third, the results of multiple regression showed that self concept explained 45.2% of clinical competency. Conclusion: Self concept has a strong influence on clinical competency. Therefore, individualized nursing management strategies and education programs must be developed in order to increase a nurses self concept.

  • This case study takes a look at the hyperlink networks extracted from the websites of 367 international non-governmental organizations (NGOs) with datasets from 2010, 2012 and 2014. The first level of evaluation focuses on connections between the NGOs, identifying important nodes, groups and their relations. The second level takes into account the broad range of networked websites from the World Wide Web delivering insights into general networking patterns. The third level explores the underlying spatial configurations of the network which offers a great variety of geographic insights on information flows between and within continents, countries and cities. The most interesting findings of this study are a low level of interconnectedness between the NGOs and at the same time a strong spatial concentration of all embedded network actors.

  • Rapid urban growth is characterized in most developing countries. Overurbanization, in this paper, which means rural-urban migration continues to exceed rates of urban job creation, thus leading to a less than optimal allocation of labor between the rural and urban sectors. In consequence of over-urbanization third world cities are suffering unemployment, underemployment and misemployment. Rural-urban migration, a few years ago, was viewed favorably with regards to the economic development, but recent developing countries are experiencing the opposite. Rural-urban expected income differential can act to exacerbate the urban unemployment situation even though urban employment might expand as a direct result of governement policy. Agricultural investment, especially land saving technology - irrigation, drainage, etc. - and rural industrialization seems to be the best policy to reduce overurbanization.

  • Recently, there is the huge interest to promote the export of Korean agro-food to Chinese market. However, small number of papers analyze the Chinese consumer to find the strategy for launching Korean agro-food in Chinese market. The purpose of this paper is to analyze Chinese consumer for Korean agro-food in Chine. Survey analysis was conducted in 4 big city (Beijing, Shanghai, Guangzhou, and Tsingtao) for this research. The results of studies present a few findings: First, many Chinese consumers prefer Korean agro-food. Second, among big cities, Beijing shows the highest level of preference for Korean agro-food, Third, Chinese consumers can pay higher price for Korean agro-food, Fourth, Chinese consumer usually buy small amount of agro-food. Fifth, the image of Korea is also important to promote the exportation of Korean agro-food to Chinese market.

  • This technical paper presents a detailed review of the stack effect phenomenon and of the associated implications pertaining to the design and construction of high-rise buildings in regions of extreme climatic conditions. The present review is focused on both the classical 'chimney' effect as well as on the reverse stack effect, which are respectively related to cold and hot climates. For the purposed of the work here presented, the ASHRAE (2013) design conditions of Astana (Kazakhstan) and Riyadh (Kingdom of Saudi Arabia) were selected. A 230 m tall residential building of rectangular floor plan was numerically modelled in the context of the climatic conditions of the two abovementioned cities and a number of sensitivity analyses were performed, covering parametric changes of: temperature, façade air tightness, site wind speeds and wind directions.

  • Energy demands for offices in Korea are surveyed and analyzed to generate communicational models for simulations. Daily energy loads of 13 office buildings scattered in the 6 largest cities in the country are surveyed and analyzed based on energy consumption log sheets. Detailed hourly loads that are frequently required when a detailed operation simulation is performed are measured using remote data acquisition processes for 3 offices. The complete load demand models of electricity, cooling, heating and hot water are established by combining the daily and hourly patterns based on the statistical behavior of the hourly patterns.

  • The abuse of zipeprol, an antitussive agent, was found to be most prevalent among young people in Korea. Because abusers take large doses of this drug for its hallucinogenic effects, fatalities from zipeprol overdose abuse have been on the rise since 1991. Since 1991, a total of 69 zipeprol-related deaths have occurred throughout the nation. A demographic study shows that in ninety six percent of cases involving zipeprol alone, the victims were in their teens and twenties. The mate/female ratio in zipeprol related death was 3.5:1. Most of these zipeprol-associated deaths occurred in the larger cities of Seoul and Inchon. The blood concentration of zipeprol ranged from 0.8 to $38.3{\mu}g/mL $in single drug involved deaths, while zipeprol varied from to 35.3 $0.1{\mu}g/mL $in zipeprol and dextromethorphan victims.

  • LRT (Light Rail Transit) is one of the transport modes to reduce heavy traffic in big cities and intercity. LRT line is considered to be easily linked with other transport system. The importance of new LRT lines has recently emerged as the problems solution in Korea. Thus, in this study, the turnout for AGT (Automated Guideway Transit) by computer system has been developed. And Guideway for AGT has also been developed for installation on the LRT line as well. In future, if the results of the feasibility study show the new LRT line project is viable, Kangwon Railtech shall propose design for LRT turnout, development, standardized design for guideway, and construction scheme
