  • Australia has joined many governments to adopt public-private partnership (PPP) as a major strategy for procuring infrastructure for decades. However, failures have occurred although the market has been considered to be a mature and sophisticated one. Failures have typically been traced back to inappropriate economic evaluation and a lack of value-for-money. In particular, a literature review has identified that there was no holistic consideration on the evaluation of procurement transactions of PPP projects. The transaction costs of PPPs were not handled properly. In this paper, theories of transaction cost economics are proposed for the purpose of such a holistic institutional economic evaluation. These theories are analysed in order to identify potential critical success factors for a strategic infrastructure procurement framework. The potential critical success factors are identified and grouped into a number of categories that match the theories of transaction cost economics. These categories include (1) Asset Specificity, (2) Organizational Capability, (3) Transaction Frequency, (4) Behavioural Uncertainty, and (5) Environmental Uncertainty. These potential critical success factors may be subject to an empirical test in the future. The proposed framework will offer decision makers with an insight into project life cycle economic outcomes needed to successfully deliver PPPs.

  • Various ways of automated guideway transit construction are being planned recently owing to the policies of the national government and local municipalities as well as increasing investment from the private sector. Particularly, the increase in the private investment is increasing greatly in SOC (Social Overhead Cost). This trend of promoting private sector investment must be conducted on the basis of a thorough analysis of the economic feasibility of the project from the government and construction companies in the private sector. In other words, an accurate cost analysis of initial investment cost (Construction cost), maintenance/repair cost, profit making through the operation of the concerned facilities, cost of dissolution, etc. in terms of the life cycle is very much in need. Nevertheless, the analysis of uncertainty factors and its probabilistic theory are in need of development so that they can be used in the analysis of the economic feasibility of a construction project. First of all, the actual studies on maintenance/repair cost of automated guideway transit are scarce as of yet, prohibiting an accurate computation of the cost and its economic analysis. Accordingly, this study focused on the uncertainty analysis of the economic feasibility for civil engineering structures among automated guideway transit construction projects based on the rapidly increasing investment on such structures from the private sector. For this research purpose, a cost classification system for the automated guideway transit is proposed, first of all, and the data On the cost cycle of the civil structure facilities and their unit cost are collected and analyzed. Then, the uncertainty in the cost is analyzed from the perspective of LCC. In consideration of the current status with almost no. studies on maintenance/repair of such facilities, it is expected that the cost classification system and the uncertainty analysis technique proposed in this study will greatly enhance LCC analysis and economic feasibility studies for automated guideway transit projects in the future.

  • The purpose of this study is to develop Family Life Education program for Marital education in Korea. In order to realize the about research purpose, this study is divided into three sections. First, nature conception and contents f Family Life Education, second, patterns and models for Family Life Education Program in USA and Korea, and Third, the future of Family Life Education. Family Life Education (FLE) is an education originated in reaction to changing social conditions, industrialization and urbanization, it deals with the perceived inadequacies of families to cope with these changes, thereby reduction social problems involved with, and improving family life. With and assumption that the studies about FLE have not been so active in Korea, the present thesis examines the FLE in Korea. The necessity of marital education in Korea Is based upon the theories of FLE in the United States of America. Also, it atempts to formulate a tentative plan for the promotion of a FLE program in Korea. The concept of FLE in Korea was manifested in the social educational law and life-span education. specified as 4th among ten presidential regulations. It is defined as " the Life-span developmental education to enhance the quality of human life, to solve family problems, to develop an individual's potentiality and to strengthen the family relations. of the FLE programs, the marital education is considered one of the furcial wubjects becaused it is the core of the family life. With this premise, FLE tries to wupport the healthy mrital relations. subsequently helping to explore the family potentiality and to strengthen family ties. The objects of the FLE program are unmarried, pre-marred , and married persons. For the married persons, the FLE program should be arranged in accordance with their rrital status divided by the family life cycle so that they may prevent possible family problems at each stage of the family life. Also, to prevent the problems occurred in the course of carrying out family functions, the FLE program should be provided with on the basis of a family unit, thereby improving the quality of the family functions. The FLE is to hep persons begin smoothly the adaption process for a successful marital relations. For the FLE to be practised more widely systematically, research on family education--that is basic study, research and production and evaluation or the FLE to be carried out by research institute wholly responsible for it-- should be done first.

  • This study attempted to develop integrated family policy. For this purpose, a delphi survey was conducted twice among 15 professionals regarding the general contents of family policy, the goals and outcomes of president Roh's administration, the direction and plan of action for future family policy. The results of this study are as follows: Firstly, the main results of president Roh's administration were the creation of the Ministry of Women and Families, and the Healthy Families Law. Nevertheless, that government had no long-term vision or action programs. Secondly, there are two aspects of family policy which one is family members based and the other is family life cycle based. Accordingly the subjects of this study insist that family policy has to cover people's whole life, all families regardless of family structure, and has to integrate the plans and programs which have been served to individuals, for example, women, child, youth, and elderly. Thirdly, the orientations of future family policy are to be toward happiness, health, equality, coexistence, harmony, growth, generosity, diversity, self-control, and a sustainable society. So the concept of the integrated family policy has to cover all aspects of the family and the diversity of family life. Therefore, the service delivery system for family policy has to converge into the Healthy Family Center.

  • Electric vehicles (EVs) are spreading rapidly and many counties are promoting hybrid and fully EVs through legislation. Therefore, an increasing amount of lithium ion batteries will reach the end of their usable life and will require effective and sustainable end-of-life management plan which include landfill disposal or incineration. The current research focuses on more sustainable methods such as remanufacturing, reuse and recycling in order to prepare for future battery compositions and provide insights to the need recycling methods to be developed to handle large amounts of batteries sustainably in the near future. The two most prominent material recovery techniques are hydrometallurgy and pyrometallurgy which are explored and assessed on their relative effectiveness, sustainability, and feasibility. Hydrometallurgy is a superior recycling method due to high material recovery and purity, very low emissions, high prevalence of chemical reuse and implementation of environmentally sustainable compounds. Expanding recycling technologies globally should take the research and technologies pioneered by Umicore to establish a sustainable recycling program for end-of-life EVs batteries. Emerging battery technology of Telsa show the most effective designs for high performance batteries includes the use of silicon which is expected to increase capacity of batteries in the future.

  • This study was conducted as a part of the project developing the standards of national board test for the dietitian's licence. The purpose of this study was to define the job description of dietitians, and to describe the task elements based on the detailed analysis of the dietitians' work. This study team established the research team which was composed of food and nutrition experts, 7 of registered dietitians and 3 of university professors. Draft job description form was made to fully explain the dietitians' task elements, process and sequence by the research team. Final job description form was confirmed after the validity of 576 task elements was reevaluated upon 4 point scale test based on the frequency, importance, and difficulty by 21 field registered dietitian by the study team. It was also confirmed by the university. This form was formated by following DACUM method which analyzed the job description containing duty, task and task elements. It was organized to include every dietitians' work and to describe the every detailed process of work. Duty was defined as the specific and independent work as a dietitian, and was composed of 17 parts, i.e 10 parts in food supply management area and 6 parts in nutritional care service area and self promotion area. Duties were also divided into 99 tasks containing the 576 detailed task elements to describe definite action, steps and decisions. Seventeen parts are following; menu planning, storage and inventory control, food production, meal service, waste management, sanitation, equipment and facility management, human resource management, financial management, nutrition assessment of life cycle, nutritional assessment of several disease, nutritional assessment in specific condition, medical nutrition therapy, nutritional education, public health nutrition and self promotion. If these protocols are properly performed and presented, they can provide the likelihood that dietetics professionals work as a primary contributors in promoting health care and preventing disease nationally.

  • SCM activities in a company are considered as total innovation through synchronizing supply and demand while maintaining appropriate inventory level and reducing the business operating costs. Until now, even several researches are carried out on the SCM performance of the companies which have introduced and been operating SCM, the research on the cost analysis for the inventory which occurs frequently on supply chain is still insufficient. Especially, for the electronics industry in which the product depreciation is sharp caused by the short product life cycle and the complexity of distribution channels, even the inventory related costs are a major factor in business management, since the current estimated criteria of inventory costs are limited to the interest and maintenance management costs, the criteria do not reflect the total influence of the product depreciation and lost opportunity cost which are related to the business management. Furthermore, even though the rapid price drops of the distributor inventory caused by the frequent new model launch can be covered by the product manufacturers, the scale of total costs related to the inventory has not been conceived because the price compensation is traditionally considered as a market costs. In this research, we analyzed the inventory characteristics of electronics industry in which the price depreciation happens frequently, newly defining the estimated criteria of the product total inventory cost which includes price depreciation from the product manufacturers' view. Finally we focus on the case study of a representative electronics company and verify the scale of the influence on management performance.

  • Since the size of the construction project has become massive, complicated and specialized, the use for a substantial amount of information provided from diverse participants is considered important. Schedule information obtained from a variety of sources is key during the construction project. Misunderstanding of schedule management information causes delay of construction period and low quality of construction. Currently, interest in BIM (Building Information Modeling) that produces the necessary data for the entire life cycle of the building process is rising. The study is to construct the BIM-base-information system in order to systematically manage schedule information of the construction work. For this purpose, the study established a BIM-base-schedule-management-business process and drew a classification system for the work for schedule-information construction. The study also drew information that can be extracted from the BIM model among properties required to build certain information. The schedule is made upon consideration of information needed for schedule management, and information required to schedule a timeline of the construction project by process is established.

  • The national investment versus research result management ratio is very low as we compare to those of other advanced countries. Also the system of efficient usage of research result is insufficient. It results inefficient R&D investment when we drive national R&D programs. In this paper we developed a generalized information system for efficient planning and management of national R&D programs. And we developed a efficient system of the R&D information support and a system of a smoothly circulating R&D information. Also we apply those systems to the development of the information system of Korea Research Council of Fundamental science and technology. This application system can provide a total R&D information of whole life cycle of the national R&D programs.
