To analyze main factors of size planning of community facilities that were created as part of development of a rural area, the present condition of factors deciding size of community facilities was analyzed, factors that influence size planning by the type of community facility were drawn with Delphi anaysis. The results of analyzing the present condition of size planning factors of community facilities show that facilities have been generally planned as multi-purpose and multi-functional facilities. And on the basis of the purpose of facilities, their functions and organization, and their operation programs, facilities are classified into community-centered, agritourism-centered, and combined ones. Using Delphi analysis, major factors that could affect size planning of community facilities were drawn on 26 community-centered, 28 agritourism-centered, and 30 combined. And the factors tended not to be applied well for size planning of community facilities.

In process planning for pocket machining, the selection of tool size, tool path, overlap distance, and the calculation of machining time are very important factors to obtain the optimal process planning result. Among those factors, the tool size is the most important one because the others depend on tool size. And also, it is not easy to determine the optimal tool size even though the shape of pocket is simple. Therefore, the optimal selection of tool size is the most essential task in process planning for machining a pocket. This paper presents a method for selecting optimal toos in pocket machining. The branch and bound method is applied to select the optimal tools which minimize the machining time by using the range of feasible tools and the breadth-first search.

The purpose of this study is : first, to examine factors of fashion show planning and production and to classify types of fashion show planning and production: second, to compare and analyze the factors through a case analysis to defined their differences. For the purpose, data are collected to compare and analyze from literature as well as the interview with fashion show planning and production companies in Korea. The result shows that all the factors are considered on a practical level except security and publicity among 15 factors presented in literature : the purpose of the show, target spectators, product selection, product prices, type of show, size, location, models, time of show, duration, theme, security, budget, and publicity. Show types are divided into national brands, designer brands, imported brands, and collections. The result of the comparison and analysis of the factors of the planning and production by type shows that factors vary greatly depending on the purpose of the show, target spectators, and form of the show and products. By analyzing the case study on fashion show planning and production on a practical level, the study recognizing the need of specialized development of fashion show planning in Korea's fashion industry, is a basic process of theory systematization for the planning and production in its marketing aspects, and will provide relevant theories in such aspects for those who want to enter into the field.

Every year new tall buildings are being conceived, designed, and built with new schemes. Thus it is important to explore the factors that affect tall building design. Thus it is important to explore the tall building design factors. The planning and design of tall buildings require different criteria than those that exist in regular size buildings. Tall buildings are uniquely expressed by their structural systems where exterior esthetic and requirements of space drive the form and composition of the structural systems. Therefore the exploration of design factors is the key to achieve optimum building systems. Optimization as mentioned here is associated with the efficiency of the different building systems. To achieve an optimal system, there is a need for an understanding of the factors that affect on overall tall building design such as planning module, building function, lease span, floor-to-floor-height, building height (aspect ratio), structural system, environmental systems. In this paper a statistical approach will be used and will be based on data collected from the practice through a rigorous survey taken. This information is tabulated and analyzed. The major target of investigation will be lease span related to space requirement in the tall building planning. Factors related to lease spans, such as function, floor-to-floor height, planning module, building height, overall plan dimension, and plan ratio (building geometry), will be looked at carefully. IN conclusion, this approach of optimization can introduce a preliminary design guideline for tall building projects. The purpose of the paper should shed some light on the optimum tall building design criteria.

Whenever planning a study design or preparing a research proposal it is highly recommended that investigators decide the optimum sample size that is required to yield an outcome of interest with a predetermined level of precision. This is because that, all else being equal, if a study with less than the optimum sample size would not detect the significance of differences in reality, and similarly, if a study with more than the optimum sample size will be costly. For these reasons, the majority of peer reviewed biomedical journals assess the adequacy of sample size requirements. The calculated sample size is used as a target number of samples to be collected to provide an estimate of the parameter with the desired and predetermined level of accuracy, and the sample size is a major determinant of the probability of detecting diseased animals from the population. There is no single method of calculating sample size for any given study design. In this context, the purpose of this article is to provide a collection of formulas and examples for some typical situations likely to be encountered in veterinary clinical practice and to highlight the importance of performing prospective sample size calculations when planning a research. Specifically, this paper is concerned with the basic principle of sample size calculation, and considerations for methodological applications were illustrated for a given data set. Also included in this paper is factors influencing sample size calculations using a statistically valid techniques. Appropriate methods to consider these factors are presented.

Korean family planning program has been adopted as a part of the Economic Development Plan with strong national government backup. After initiation of family planning program, the increase rate of total population declined from 2.6 percent during 1955-1960, to 2.1 percent in 1960-1975, and 1.6 percent in 1979. Of course, we do not ascribe this population increase rate decline to the national family planning program alone. Other contributing factors have been changes such as growing numbers of induced absortions, a rising marriage age and economic development. Currently, 2,600 family planning workers are assigned in all myun of the country. 21 percent of the works are registered nurse, 9 percent are midwife and aid nurses occupy 70 percent (Table 1). Authorized clinics are 2,329 which composed 1,765 IUD clinics, 1,070 vasectomy clinics and 1,150 Fimale sterilization clinics (Table 2). Cumulative contraceptive services provided by government program, 1962-1974 is illustrated in Table 3. After government program in family planning has been initiated (1962-1978), estimated number of births averted by each methods was measured (Table 4). From 1962 to 1978, tendency of contraceptive acceptors is illustrated in Table 5 showed that IUD, oral pill and condom program is decreasing and in other hand, sterilization program is increasing very much. Attitude change toward family size (1965-1978), contraceptive practice and son preference are showed in Table 7, 8, respectively. Auther concluded that future program in family planning should target to the point, that smaller family size norm for maternal health should be emphasized rather than smaller size family for national development.

Recently, the role of information system in a company has been changed a lot because of the rapid change in business environments and the development of information technology. It encompasses not only the supporting role which has aimed at improving business process but also the strategic role of which purpose lies in strategic use of information technology. Achieving this increased role of information system requires more emphasis on development of better and more effective ISP(information system planning). The purpose of this study is to identify organizational factors to affect successful information system planning. For this study, 240 survey questionnaires were mailed and 71 questionnaires were returned. 57 samples were used for the final analysis and 14 samples were excluded from analysis in that they didn't exercise official and systematic ISP. As the result of analysis, the factor which affect effective ISP is internal organization factors(size, ISP time frame, organizational planning resources, management style, organizational culture), not external factors(volatility and competitiveness). Among Internal factors, organizational culture and management style are the most significant factors which affect the effective ISP. The result of this study may have meaning in suggesting the way to develop effective ISP through the formalization of business process, more favorable users attitude toward IS and selection of an appropriate ISP methodology.

This paper addresses a model for the transportation planning that determines the transportation cycle time and the vehicle size to minimize the cost in a distribution system. The vehicle routing to minimize the transportation distance of the vehicles is also determined. A distribution system is consisted of a distribution center and many retailers. Products are transported from distribution center to retailers according to transportation planning. A model is assumed that the time horizon is continuous and infinite, and the demand of retailers is constant and deterministic. Cost factors are the transportation cost and the inventory cost, which the transportation cost is proportional to the transportation distance of vehicle when products are transported from distribution center to retailers, and the inventory cost is proportional to inventory amounts of retailers. A transportation cycle time and a vehicle size are selected among respective finite alternatives. The problem is analyzed, and a illustrative example is shown.
