POPs in sediments and soil in the PRD are comparable to or much higher than those reported in other regions. Some sites may be classified as POPs- polluted with high ecological risks. Large-scale land transform in the process of regional urbanization may facilitate the transfer of POPs in the soil to the sedimentary system by enhancing the soil run-off. Urban atmospheric PCBs in PRD are found to be less than some of the North American or European urbans, but PAHs are significantly higher. The center of the PRD has been the major source area of PAHs and organochlorine pesticides in the PRD. The northern part of the PRD serves as a regional sink for the air particulates and affiliated POPs.

The most of public services that we use these days is distributed and supplied as 'App' service because of wide spread of smat phones. Especially, since the interest of general citizens about usabilitu of public data has been increased, in case of Seoul, people can reach the data through 'Seoul Open Data Plaza' of 25 regions of Seoul. It becomes possible to construct various throughout this system. Ultimately, in case of users, they are provided many services through their electronic media. Looking at the development and research of public data service, they are mostly focusing on service or building up the service, but the research on visualization of contents is insufficient. This study is suggesting the specific plan and directionality of building public service using the public data which studied in the advanced research, "The user interface platform". Finally. this research is for a right usage of public data in the smart urban environment in near future and providing the practical public service.

According to the intercombined review of chemical and biological investigation it has been noted that the metabolizable energy per gram dietary protein of mixed diet of daily intake patterned by Korean population has been found 3.4-3.6 Cal., which entails 10-12% level of the protein calorie percentage of total metabolizable energy, the biological value being fallen within the scope 63-73. The structure of dietary protein has revealed that the lysine and isoleucine were primary limiting amino acids and threonine secondary limiting as a general trend, however, it is assumed that the ultimate nutritional effect of dietary protein might be restricted uniformly among regions by the amount of lysine, since the lysine availability has been yielded as low as 72-82% level. As for the net protein utillization NPUst falls in the range of 52-62 and the NPUop 47-58. In either part the mountainous region has demonstrated lowest value and the urban area highest, these trend being obviously associated with the ratio of animal protein relative to the vegetable origin. The net dietary protein calorie percentage (NDpCal %) has been found within the range of 5-7 that may be capable of meeting the requirement for the maintenance of adult, though for the growth it is insufficient. Present level of total caloric intake would not influence on the fate of protein value of prevailing regional diet in terms of caloric restriction, since the present intake of food energy is higher than the lower limit of caloric intake that would impair the biological performance of dietary protein fed ad libitum basis. Based on the protein efficiency, the adequacy of current level of protein intake was analyzed in terms of utilizable protein, and it has been demonstrated that the 37.8g of utilizable protein in the fishery region and 38.2g in the mountainous region were bellow the FAO recommendation. Accordin to the hematological study it may be interpreted that the anemic symptoms of the mountainous region has some possibility of being related to the inferior status of dietary protein in quality as well as in quantity.

This paper presents the measurement results of strength of electromagnetic wave for GSM-900/GSM-1800 band which is used in Europe. The Giryong village and Sosan field are selected as candidate regions according to the measurement results in Gijang-gun, Busan. The vertical polarizations is about 12 dBm higher than horizontal polarization at two candidate places, and it is measured 25 dBm lower than urban. The maximum value of measured strength of vertical polarizations in the cellular/GSM-900 bands are -65 dBm at Giryong village and -69 dBm at Sosan field, respectively. The maximum value of measured results of PCS/GSM-1800 bands are -90.5 dBm at Giryong village and -85 dBm at Sosan field, respectively, We confirm that the receiving strength of electromagnetic wave are very weak below -65 dBm at two candidate places and the signals of GSM frequency bands not affect to conversional system, then it is considered as a suitable place for GSM mobile field test.

The economic reform in China since 1978 has been increasingly sped up and deepened. The recent development of private enterprises, especially, has significant economic and political implications, whereas its regional differentiation has considerable impacts on both the development potential of certain regions and overall regional growth pattern. This study aims to understand the regional pattern of private enterprise growth as well as the institutional change which has structured the growth process. The development of private enterprises turned out to be closely tied to the marketization strategy of dual-track system and policy needs to reduce the unemployment level in both urban and 겨ral China. The regional pattern of the private enterprise growth can be characterized as ever-increasing spatial differentiation. Based on the basic statistical analysis results, it is argued that the private enterprise growth is closed related with the marketization level of the regional economy. Therefore, the strategy of developing private sector will be more important in shaping the regional development path as well as potential.

The purpose of this study are to analyze the realities and characteristics of the inflow manufacturing factories located in non-urbanized area in the Capital region, and to extract the problems from locational point of view during the last 10 years. Using the raw data of factory registration statistics from 2006 to 2015, this study has intended to show the distributional characteristics of the independently-located manufacturing factories by various mapping methods. As a result, about 90% of the factories are heavily concentrated into 10 adjacent regions to Seoul and large cities. This study carried out questionaire surveys and in-depth interview to the leaders of Janganmyeon, Hwaseong-shi which have experienced the rapid increase of manufacturing factories. The independently-located factories have caused environmental pollution, destroyed rural village landscape, and affected the negative impact of the neighborhood community. The results of this study provide some implications to establish a desirable industrial location policy of non-urban areas in Capital region.

Purpose: The purpose of the study is to suggest the main functions and implications of public hospitals to effectively respond to the future epidemic crisis based on analyzing the accessibility to designated Coronavirus Disease 2019 (COVID-19) medical institutions of Seoul and examining the main features of the quarantine of Seoul municipal hospitals. Method: To analyze the response and function of Seoul municipal hospitals, we reviewed the Infectious Disease Control and Prevention ACT, 258 articles of Seoul Metropolitan Government press releases from January to the end of April, 48 articles of Seoul Metropolitan Government's daily newsletters, 2019 Health Bureau Budget report. We also referred to internal data of Seoul Children's Hospital, Seoul Seobuk Hospital, and Seoul Eunpyeong Hospital during the same period. Besides, the accessibility to medical institutions was analyzed by using the COVID-19 data which was announced daily basis. Results: The accessibility of COVID-19 patients living in the Southeastern part of Seoul to a medical institutions was 16.2km on a distance basis, and it was the lowest accessibility among four regions of Seoul since it took about 40 minutes by car. On the other hand, patients living in the Northeast part had the highest accessibility, as the access to medical institutions was 10.7km and 27 minutes by car. Also, the main functions of the municipal hospital of Seoul against COVID-19 were to shift the public hospital function to COVID-19 patients only hospitals, to perform the epidemiological investigation by medical doctors, and to support the operation of self-isolation facilities, community treatment centers and triage rooms of community health centers. Conclusion: Through the experience of COVID-19, we suggested that the functions of public hospitals will be reorganized as the reinforcement of infectious disease treatment and mental health for quarantined patients, cooperation with private hospitals, supporting for strengthening community health capacity and preparation for another epidemic.

The present study was aimed to estimate the rational bubble by using the state space model and Kalman filter, of the national, capital, non-capital, Gangnam, and Gangbuk regions housing sales price from November 2003 to August 2013, for the whole period, and before and after the global financial crisis. For the whole period, Gangnam marked the highest rational bubble of 25.4%, followed by Gangbuk 21.3%, capital region 20.1%, whole country 18.9%, and non-capital region 14.3%. Prior to the global financial crisis, Gangnam showed 26.7% of bubble, which is approximately 7.4% higher than Gangbuk with 19.3%. On the other hand, after the global financial crisis, the bubble has collapsed a lot with Gangnam 13.2% and Gangbuk 10.7%; however, the non-capital region showed rather an increase of about 15% from 4.2% before the crisis to 9.0% after the crisis. The main cause of this is that the trading price has declined but the rents have risen in the capital region including Gangnam and Gangbuk, while the transaction price has gone up in non-capital region due to various positive signs like the moving of public institutions.

Construction of sheet pile retaining walls in urban and coastal regions has resulted in sheet pile walls in close proximity to laterally loaded pile foundations. However, there is currently little information available in the literature to assist engineers for quantifying the response of sheet pile walls. This study provides a quantitative method for estimating sheet pile wall response due to loads imposed from a nearby laterally loaded pile. Three dimensional finite element analyses using commercial software, ABAQUS, were performed to assess the response of a sheet pile wall and nearby laterally loaded pile. The soils were modeled using Drucker-Prager constitutive model with associated flow rule, and the sheet pile wall and pile foundation were assumed to behave linear elastic. Four parameters were investigated: sheet pile wall bending stiffness, distance from the pile face to the wall, excavation depth in front of the sheet pile wall, and elastic modulus of the soil. Results from the analyses have been used to develop preliminary design charts and simple equations for estimating the maximum horizontal displacement and maximum bending moment in the sheet pile wall.
