This study aims at identifying factors and variables which have significant effects on users satisfaction with recreational activities and facilities in Apsan city natural park and therby establishing indicies of planning and / or development of urban forest. To test the causal models of this research, The data were gathered by self-administered questionnaires from 1,147 households in Taegu city which were selected by the multi-stage probabiling sampling method. The analysis of the data primarily consist of two phases : The first analysis dealt with exploratory factor analysis which identified major factors involved in satisfaction with recreational activities and facilities in Apasn city natural park and the second analysis tested the fit of causal models of this research to the data using LISREL methodology. The factor analysis identified that three significant factors are involved in satisfaction with recreational activities and five significant factors are inherent in satisfaction with recreational facilities. The second phase analysis tested the fit of the causal models for satisfaction with recreational activities and facilities to the data and identified statistically significant causal linkage among overall satisfaction with the park, other indogenous factors and exogenous variables. These significant relationships represent important factors and variables that should be considered in planning and/of development of the city natural park. On the basis of there significant causal relationships implications for planning and/or development of the city natural park were suggested.

It is important for residents to give opinions and participate in urban regeneration projects. Urban regeneration college is being operated to strengthen the capacity of residents. In this study, the educational satisfaction of the students was surveyed while conducting the program of urban regeneration college. By analyzing survey, we intend to derive implications when constructing an urban regeneration college education program. The survey was conducted on 215 students from urban regeneration college in y-gun. Analysis was performed using the spss24.0 program. As a result of factor analysis, it was classified into three factors: education design, education culture, and education support. All three factors had significant differences in educational satisfaction. Satisfaction with education had a significant effect on the possibility of village development. Satisfaction was different according to the contents of the educational program according to the awareness of urban regeneration. For those who are aware of urban regeneration, educational culture among educational programs has more influence on educational satisfaction. Those who were not aware of urban regeneration had an effect on education support and education satisfaction. The results of this study can be used as basic data when planning educational programs for urban regeneration college.

The purpose of this study is to find what causes make public projects hold off, going beyond the planned deadline and budget. Using System Dynamics(SD) and their derivative Urban Dynamics(UD) models, it intends to analyze major feedback loops based on VENSIM and to simulate them with STELLA software, all of which are interrelated with various causes of project delay. To prevent or ameliorate project delay, first of all it advises to focus on endogenous delaying factors not exogenous ones. These factors either reinforce or balance certain loops in complex causal structure, In the case example on the Cremation Building Project in Cheongju, Residents’ participation demand make negotiation put off and delayed negotiation reinforces administrative-expediency planning in order to observe a time limit, on the other hand, once building consensus, it increase both the level of planning performance and public trust. In the meantime, the real planning process used to neglect residents opinions and manage public grievance only through compensation, he a result of simulation, visible fruit of negotiation in the initial phase seems to be not satisfactory owing to funds and time consumed, but after reaching an mutual agreement among stakeholders, planning performance is effective and strategic than administrative-expediency planning viewed in both financial and time angle. It proposes to devise specific tools schematizing project implementation. In order to upgrade the quality of project management, it recommends for planners to adopt key concepts based on SD/UD diagrams and causal loops, which would contribute to enriching Planning abbots.

This research investigated the preference factor which has an effect on the forms of bus stop shelter in order to grasp the visual preference factor, which is necessary for planning and designing of bus stop shelter centering around user, starting with the question of the research regarding that a shelter is preferred by what kind of factor when the environmental conditions are regular. This research examined the relation between visual preference and preference factor which has an effect on it with Multiple Regression Analysis after evaluating visual preference for shelter form by user as applying of scoring system of Interval Scale. The result of the factor analysis by visual evaluation for the form of bus stop shelter through the said research result will have an great effect on the design of bus stop shelter centering around its user. Therefore, this research result will give a knowledge which is necessary for the plan and the installation of bus stop shelter, and contributes to shelter design and bus stop promotion which can maximize the satisfaction of user. As well, concerning the management of bus stop facilities, it will give useful guidelines for planning strategically the shelter management centering around user. In particular, It is estimated that the preference factor analysis by visual evaluation of the mass transportation user in daily life will be the cardinal point for bus stop plan.

This study aims to identify the rural spatial structure and to establish the planning characteristics based on urban-rural connections strategy of North Korea. For this purpose, they were collected such as documents and drawings including primary data related to rural planning in North Korea, and the rural space were classified into three elements in order to analyze them by the rural planning's point of the view. Unlike generalized capitalist cities, socialist North Korean cities are characterized by the coexistence of urban and rural areas. This distinct feature of the city is also reflected in creating rural space in North Korea. Thus, The urban-rural integration in spatial planning is a key factor in understanding the spatial structure of North Korea. This study firstly examines the characteristics of the county(gun), the administrative and economic unit established in the post-war period, secondly, examines the planning method of town(eup) which can be called the urban center in rural areas, and lastly grasps the planning method of rural village focusing on collectivization and identifies how they are connected to the town for the shake of urban-rural integration. As a result, the characteristics of rural planning in North Korea has revealed that it has a comprehensive rural planning established with the goal of strengthening the self-sufficiency of the rural area by the means of the create of rural spatial hierarchy in the whole country.

The purpose of this study was to analyze the factors that influence middle-aged people's retirement planning and financial preparation for old age. The data was derived from "the National Survey of Families 2015". The samples included 1,462 people from 40 to 64 years of age. The findings from the analysis showed that the level of retirement planning was significantly associated with gender, age, education level, employment status, monthly family income, monthly expenditure on spending to support parents, and perceived household economic condition. When the samples were divided by sex, the results showed that the perceived household economic condition was the most significant factor for both men and women's level of retirement planning. Age and education level were the significant factors for women's level of retirement planning but not for men's. Logistic regression was used to analyze whether middle-aged people made financial preparation for old age. For the whole sample, whether or not a person was a regular employee, monthly family income, monthly expenditure on supporting parents, perceived household economic condition, and retirement planning were significant variables in determining financial preparation. For men, whether or not a person was a regular employee, monthly family income, perceived household economic condition, and retirement planning were significant factors, for women whether or not a person was a regular employee, and retirement planning were the significant factors in determining financial preparation. The results implied that retirement planning is needed for middle-aged people to prepare for old age financially while the financial preparation should differ depending on sex.

Seasonal water requirements by paddy rice is important to water budgeting for the water resources planning at a basin scale. This paper compares the water requirements resulting from different approaches for the Han River Basin. The demands from the drought years of 1967 and 1968 were found to be significantly less than the irrigation standards. This may result in significant underestimation of the basin-wide water demands. A conversion factor method is proposed to define seasonal irrigation demands. The factor is defined from the ratios of the standards for each growing stage to the drought year demands. The results were compared satisfactorily with those from the irrigation standards, and readily applicable to the water resources planning.
