  • In order to explane the stereotactic procedure, the three steps of the procedure (target localization, dose planning, and radiation treatment) must be examined separately. The ultimate accuracy of the full procedure is dependent on each of these steps and on the consistancy of the approach The concern in this article was about dose planning, which is a important factor to the success of radiation treatment. The major factor in dose planning is a dosimetry system to evaluate the dose delivered to the target and normal tissues in the patient, while it generates an optimal dose distribution that will satisfy a set of clinical criteria for the patient. A three-dimensional treatment planning program is a prerequisite for treatment plan optimization. It must cover 3-D methods for representing the patient, the dose distributions, and beam settings. The major problems and possible modelings about 3-D factors and optimization technique were discussed to simplify and solve the problems associatied with 3-D optimization, with relative ease and efficiency. These modification can simplify the optimization problem while saving time, and can be used to develop reference dose planning system to prepare standard guideline for the selection of optimum beam parameters, such as the target position, collimator size, arc spacing, the variation in arc length and weight. The method yields good results which can then be simulated and tailored to the individual case. The procedure needed for dose planning in stereotactic radiosurgery is shown in figure 1.

  • Public rental housing in Korea has been initially provided for residential stability of low-income household focusing on solving quantitative insufficiency since 1980s. In the process of early stage of designing and planning public rental housing, qualitative aspects of considering children were not primary concern. This study aims to analyze the priority of environmental improvement of outdoor spaces for children's safety in public rental housing. First, literature review was performed in the reference of local residential safety guidelines, Universal Design, and CPTED guidelines. In each guidelines, common safety planning factors for children were extracted within different types of outdoor spaces. Second, based on literature analysis, residents evaluated importance and satisfaction level by different safety types, outdoor space type, and environmental planning factors. In results, residents evaluated high importance and showed low satisfaction for crime and traffic safety. Through IPA, facilities and parking space was evaluated where improvement is needed for the first priority, and planning factors were mostly concerned with surveillance and safety management system. Result shows general concern of public rental housing residents, about weak facility management and security system, and about socially isolated environment which heightened the fear of crime safety. Overall, poor maintenance of the complex environment and decrepit facilities are constantly raising risk of safety accidents especially for children. Considering residents' concern, environmental improvement should be considered in perspective of not only physical repair, but also facility management and security system.

  • This study investigated Korean and Chinese female college students' retirement attitudes. Considering the fact that the two countries are experiencing dramatic increases in elderly population, retirement planning is a significant social issue. Even though Korea and China share similar cultural backgrounds, economic systems and governmental retirement policies have been developed in different ways. The purpose of this research was to compare retirement attitudes and related factors between Korean and Chinese female college students. Based on a survey with 214 female college students (130 Koreans and 84 Chinese), differences and similarities in retirement attitudes and related factors were identified. On average, Chinese female college students showed more positive attitudes towards retirement than Korean students. The levels of thinking about retirement and worrying about finances in retirement were greater for Korean students than Chinese students. More Korean students anticipated that their actual retirement age will be earlier than their desired retirement age. Korean students believed that they should start retirement planning at an earlier age than Chinese students' retirement planning age. Korean students anticipated that the cost for food and housing as the major expenditure category in retirement while Chinese students anticipated cost for health care as the major expenditure category. Korean students who worry about finances in retirement, and those who anticipated that they will retire earlier than their desired age showed negative retirement attitudes when controlling other factors. Implications for retirement planning and education were presented based on the research findings.

  • Purpose: The planning of medical facilities involves formulating a comprehensive medical basic plan, translating it into spatial dimensions through a space program. Feasibility assessment often relies on empirical methods like floor area per bed. However, with the shift towards specialized medical concepts, proportional scaling to bed numbers is challenging. This study proposes scale planning improvements during the feasibility assessment stage for comprehensive hospitals, analyzing cases using area determination factors and standard areas based on medical resources. Methods: The Korean Development Institute's Public Investment Management Center (KDI) identified issues in the scale determination of medical facilities in the Preliminary Feasibility Study Guidelines and investigated alternative approaches for determining the scale of a case that passed the preliminary feasibility study in 2019. The study assessed the feasibility of applying individual factors to determine not only the number of beds but also the scale at the sector and department levels. Additionally, a statistical analysis was conducted to examine the correlation between the total number of beds and various area determination factors. Results: Results suggest a strong correlation between total beds and major equipment needs, but in hospitals with <500 beds, this correlation weakens. Ward section scale is better calculated per ward type, not just total beds. Outpatient department scale depends on specialists, influencing treatment room numbers. Medical personnel play a crucial role in determining the scale of sections like rehabilitation therapy rooms, operating rooms, dialysis rooms, and overall facility scale.

  • Long distance trail or trail system planning is the first important step in transforming your vision into reality. Planning presents a vision for a trail or trail system and brings a comprehensive, long-range perspective. The master plan provides solid, credible recommendations for developing a trail or trail system that is safe, convenient, well used, supported by local residents, practicality to implement, and customized to meet the needs of the community, you will need to follow a logical planning. The key elements of master planning includes site assessment, vision, goals and objectives, routing and design, implementation strategies. Trails or trail systems should provide linkages to popular destinations, safely accommodate a variety of users, and be sensitive to any negative impacts on the natural environment and wildlife. Trails planners also need to think about how the trail, or trail system will function in the future as areas are developed or trail population increases. All of these factors during the planning process will ensure the existence of high-quality facilities for years to come. Project for Nakdong-jungmaek trail planning combine long distance trail with circuit way. That project is a planning brought out the best in each of Tokai natural way and Cotswold way. That is planning which is combined a wooded trail in Tokai natural way with access and facilities improving economy in Cotswold way. Also That planning embraces a core cultural center which is concerned forest or wood to come more people.

  • The purpose of this study was to find out awareness of the environment-friendly planning elements for residential unit space among practitioners. The respondents in this questionnaire survey were 140 practitioners in architecture and interior design field. The major findings of this study were as follows; most of the respondents were aware of the impact of indoor built environment on residents' wellness. In addition, the survey respondents viewed that the factors for planning environment-friendly high-rise apartments were represented by gardening and energy-saving while their perception on the concept excluded comprehensive components affecting residents' life quality. Over 50% of respondents had an experience of applying environment-friendly planning elements in their works, and high frequency appeared on the general planning elements which had been applied special awareness as pro-environmental features. The respondents considered environment-friendly planning elements as important. Specially, space planning and system were considered more likely important in interior design field. In application of environment-friendly planning elements, cost, lack of consumers' awareness of and underdevelopment of environment-friendly materials were of concern. Therefore, the consumer's cognition needs to be improved for wide application about environment-friendly planning element, and then consumers are willing to pay additional construction cost of environment-friendly apartments. At the same time, the current practice that housing developers pass the additional cost on to residents needs to be changed. Then, the quality of life in high-rise residential settings can be improved. More importantly, the exchange and development of the reliable information on environment-friendly planning elements need to be made, and technical support and long-term policy for the development are required. This research showed current status of knowledge and practice in sustainable planning of unit apartment and proved basic information for future direction.

  • This study targets the urban park corresponding to the core areas (Hubs) of Green Infrastructure and estimates their value utilizing the Contingent Valuation Method (CVM) and determines the planning factors which affect them. The research aims to provide basic data for supporting the value improvement in the planning stage for urban parks representing green infrastructure. The primary purpose of this research is to derive variables that affect economic value and planning factors to improve the use-value of urban parks, one of the Hubs of the green infrastructure. In this study, Sejong Lake Park, located in Sejong City, is the target site. This study collected the responses of 105 people by conducting a survey on the intention to pay for the use-value and the planning factors that affect it, targeting visitors to Sejong Lake Park. The study conducts Contingent Valuation Method (CVM) on this survey responses. The results are as follows: first, as a result of analyzing the variables which affect willingness to pay for use-value, residence and age influence the willingness to pay significantly among socioeconomic characteristics. Next, the survey responses of Double-bounded dichotomous choices (DB-DC) CVM are converted into variables through statistic techniques. Furthermore, the variables are used for a Logit model to draw coefficients. The average willingness to pay per person for the use-value of Sejong Lake Park using the derived coefficients was approximately found to be 8,597 won. Therefore, as of 2019, Sejong Lake Park, with a total of 430,000 visitors, is estimated to have an annual economic value of 3.7 billion won. Third, the average Likert scale of the planning factor affecting the decision to pay for the economic value of Sejong Lake Park was the highest along the waterfront landscape, and the convenience facilities and waterfront landscape showed the highest willingness to pay, 10,000 won. In the range between 2,500 won and 5,000 won, the waterfront area ranks highest. Therefore, it can be said that visitors to Sejong Lake Park take account of the economic value of using the waterfront landscape the most. This study is meaningful as a thesis on use-value and the planning factors that affected value evaluation results of urban parks, and the analysis of the correlation between the planning factors of urban parks as hubs located in urban areas.
