The main purpose of the article is to study the features of the impact of social and digital changes on the system of government regulation of banking acitivity. The digital economy sets the vector along which socio-economic systems of micro-, meso-, macro-levels will develop in the long term, which necessitates research and a comprehensive analysis of digital transformation processes. Once a priority for individual innovative companies, today digital transformation has become a mass phenomenon, and the corresponding projects are vital for the success of not only individual companies, but also regions and countries. At the same time, this transformation itself is closely connected with the trend of servicing socio-economic systems and is largely implemented on its basis. Moreover, this relationship and the mechanism for its implementation remain insufficiently studied, which necessitates the development of tools for its identification, assessment and management. As a result of the analysis, the key aspects of the impact of social and digital changes on the system of state regulation of banking activities were identified.

A phenomenon in the unplanned urban sprawl of Cheong-ju city has to be rest-rained from disposing and to develop, though progress in urbanization inevitably decreases rural area. So, this thesis aims at reviewing, revising and guiding toward the more effective land use planning practice and zoning mechanism and system of Cheong-ju city. I proposed that land use planning should be had several factors and thereupon that Korean zoning mechanism and system including Building Code should be amended because of inducing human activities in buildings and facilities not to demarcate and plan every one of them. First, the factors of urban planning are a rather diversified approach to it than a unified, supplementation of the applicable difference in time between preparing and appling it, a solid controlling system, a micro and macro planning theory and giving serious consideration for the inertia from the existing land use. Second, the applicable amendments for our zoning mechanism including Eluding Code are as follows; a need of reorganization for Zoning Ordinance appricated to different regulation concerning a scale and peculiarity of a oily, a decision of the different earmarked confinement in area to different zone ana from Zoning Ordinance in City Planning Law, a demarcated facilities and the more detailed land use concerning human activies than the exsisting and entrusting decision on the ways and processes of it to every rural city planning committee, a settlement of zone ana area considering for block-unit and Planned Unit Development(P. U. D.), and a need of security jurisprudence in order to solve the zoning regulation rather in City Planning Law than in Building Code that our zoning regulation and controlling system are depended on. According to these applicable amendments to Cheong-ju city, I proposed the conceptions of Cheong-ju city land use planning are as follows; a reinforcement with one cored pattern of urban land use, a selection of gradual urban sprawl by way of city development and renewal, a strengthening accessibility to the core of the city with Plurizing the system of arterial roads, a choice of priority to conservation at the core of tile city and security of open spaces and parking area at the area of the city, a harmonization between development and conservation at the inner ring area that is situated between the core and periphery reserved area in order to develop in the future, a buffered open space situated at the congested area with heterogenous functions, and a completion of urban open space system. The proposal made here so far is for the hope of the better structure of Cheong-ju city that should be granted to the peculiarity developed with educational, cultural, conservative and self-sufficient city functions.

This study attempts to propose a priority of national nutrition targets and strategies for health promotion by the year 2000 in Korea, as a part of the task set for national health promotion objectives and strategies. Among all of the important health issues raised, ten were chosen, nutrition was one priority area. In the first part, the current status of the nutrition-related health problems and risk factors are reviewed, in conjunction with the newly arisen health phenomena, such as changes in prevalence of lifestyle disease and causes of death, changes of food consumption patterns in our country. In the second section this study suggests six feasible national nutrition targets, eight implementing strategies and current major tasks on the basis of the assessment of present status and in consideration of the other health promotion goals and strategies, with reference to that of other developed countries. The main targets and strategies are suggested as follows ; Firstly, the national nutrition monitoring and surveillance system should be established for identifying the nutritional problems for our people, and current National Nutrition Survey is a strong need for improvement to a more comprehensive and reliable one. Secondly, effective administrative mechanism should be operation at national level for the development of nutrition policy. Ministry of Health and Welfare (MOHW) as well as local health department must be remarkably renewed and strengthened the nutrition section. And it is recommended that MOHW organize and operate “The Council of Nutrition”, in which all government authorities related with foodstuffs and nutrition would incorporated. The Council of Nutrition would act as an adjustor as well as a coordinator in nutrition related policy-making. Thirdly, healthy eating pattern will be supported by activities of introducing a nutrition labeling for providing consumers with the necessary information and skills for food selection. Fourthly, nutrition education, and nutrition intervention programs will be carried out in various settings such as health centers, schools, and clinical fields and workplace. Fifthly, the current dietary guidelines shall be continuously improved in detail, and publicly circulated to particular levels of people by age group and by health condition. And finally, researches and epidemiological studies particularly in regard to diet for development of chronic diseases are needed for more investigation and up-to-date national health and nutrition data should be collected with the support and cooperation from the various medical professional teams .

This study investigates the distribution characteristics and relationship of water quality, and analyzes the spatial and temporal variation and distribution of the pollutant loads at Yeong-il Bay. The results of these analysis, the concentrations of nutrient loads (T-N and T-P), both appeared to be at the maximum value in November, while most small values were taken in May for the T-N, and in August for the T-P. For COD, the maximum concentration was in August, which has much precipitation during the same season, T-N was at the mean, and T-P was at the minimum value. Using the cluster analysis to develop the division of the sea basin by the dendrogram, before and after construction of Pohang New-port, the variation characteristics of water quality of Yeong-il Bay were discussed. The in flowing pollutant loads were transported to the landward by the high-density salinity water volume of the bottom layer therefore, it formed nutrient trap or coastal trapping areas of the pollutant load. By this mechanism, it is clear that the water volume with high-density nutrient exists on both sides of the Pohang New-port. Thus, the sea basins increasing concentration of the pollutant load at Yeong-il Bay are most prevalent at Hyeong-san estuary, the Pohang Old, and New-port. To improve water quality of this sea basin, the reduction of these nutrients loads should be the highest priority.

오늘날 무선 네트워크는 통신에서 매우 중요한 역할을 하고 있다. 예를 들어, 오늘날의 무선 네트워크는 이메일, FTP와 같은 기본 서비스로부터 웹 서비스 같은 멀티미디어 응용 서비스를 제공하고 있다. 무선 네트워크에서의 이와 같은 다양한 응용들의 서비스 질에 대한 요구는 유선 네트워크에서와 마찬가지로 무선 네트워크에서도 계속 이어질 것이 확실하다. 최근에 인터넷에서 서비스의 차별화를 지원하려는 많은 연구가 이루어지고 있다. 그러나 무선 환경에서는 제한된 대역폭과 채널 상태의 변화로 인하여 이러한 차별화서비스 지원이 더욱 어렵다. 본 논문에서는 실시간 트래픽 서비스와 비실시간 트래픽 서비스가 공존하는 인터넷 환경에서 실시간 트래픽 서비스의 질을 지원하는 수정된 무선 토큰링 프로토콜을 제안하고 있다. 제안된 알고리즘에서는 실시간 트래픽 서비스 노드가 비실시간 트래픽 서비스 노드보다 토큰 수신에 있어서 우선권을 가진다. 따라서 제안된 알고리즘은 실시간 트래픽 서비스 노드의 빠른 전송을 지원하며, 또한 기존의 토큰 전송 방식에 약간의 수정만을 통하여 QoS를 지원하는 장점을 가진다. 또한 본 논문에서는 손실된 토큰 회복 메커니즘에 대한 고찰이 이루어진다.
