Recently, the demand on the practical application of life-cycle cost effectiveness for design and rehabilitation of structure is rapidly growing unprecedently in engineering practice. Accordingly, in the 21st century, it is almost obvious that life-cycle cost together with value engineering will become a new paradigm for all engineering decision problems in practice. However, in spite of impressive progress in the researches on the LCC, the most researches have only focused on the Deterministic or Probabilistic LCC analysis approach (Level-1 LCC Model) at design stage. Thus, the goal of this study is to develop a practical and realistic methodology for the Lifetime risk based Life-Cycle Cost (LCC)-effective optimum decision-making at design stage.

This study was conducted to research the status, history and prospects of farm scale milk processing and to develop a management strategy for small scale milk process plant in Korea. Also it aims to provide ways to apply it so as to vitalize the farm made milk products market practically. This study was also treats the practical development of dairy farm school programs through the farm scale milk processing. Farm-scale milk plant (FMP) should be some of the ideas to develop small scale and using the resources according to the local features, limited expanding in regional market, produce by consumers order amounts, management policy will be transferred organic dairy farm. A few policy suggestions to put FMP system of financial support would not from beginner, it is better to settled FMP system by government or co-operation group in practical support programs were proposed. What the state needs to do through direct involvement were to put efforts at demand expansion on FMP system products, to certificate and safety the farm made milk products marketing system settings, to build more variation chance of the milk products. What was more important, however, was support policy, to create the network of FMP market and to develop of training program contents for each FMP operation unit. The ideal FMP model for the development of Dairy Farming proposed in this research will be applied as a relevant reference in managing and realizing environmental friendly and sustainable dairy industry at the national level.

Purpose: In the Korean railway infrastructure process, contractors and operators are involved at a later stage, which results in significant inefficiency. This study examines the benefits of early stakeholder involvement in Korean railway infrastructure projects and provides practical guidelines. Design, data and methodology: Literatures and foreign cases are analyzed. Building on the new product development model, we derive propositions explaining the relationship between early stakeholder involvement and the performance of Korean railway infrastructure project. Results: Major propositions include that early involvement of contractor has a positive effect on the project performance by shortening the infrastructure construction period and that early involvement of railway operator has a positive effect on the project performance by improving the effectiveness of railway infrastructure. Four requirements for the success of early stakeholder involvement are addressed. Conclusions: This study suggests that early stakeholder involvement shortens the construction period and improves railway infrastructure effectiveness. Academic contribution is to present the framework on railway infrastructure projects as holistic interactions among stakeholders. Practical contribution is to provide railway policy makers and other business practitioners with policy guidelines to improve railway infrastructure project process and to recommend an open access to relevant data.

The Nuclear Safety Commission amended the Nuclear Safety Act by strengthening the safety management system for the frequent workers to the level of radiation workers. And students entering radiation management zones for testing and practical purposes are subject to frequent workers. It is inevitable that this will incur additional costs. In this paper, the validity of the amendment to the Nuclear Safety Act was to be assessed in terms of radiation protection. Study subjects are from 2014 to 2016, among university students in Seong-nam Korea and comparisons for analyses were made taking into account variables that are differences in annual, practical types, on-class and clinical practice students exposure dose. The analysis showed that exposures between on-class and clinical practice received were less than the annual dose limit of 1 mSv for the public. Then, some alternatives that excluding from frequent workers during on-class practice or mitigating the frequent workers' safety regulation for only on-class frequent workers can be considered. Optimization is how rational is the reduction in exposure dose to the costs required. Therefore, the results are hardly considered for optimization. If the data accumulated, it could be considered that the revision of the act could be evaluated and improved.

Although retailers deals with a large number of single-term inventory items, but few cases have been considered in the areas of practical decision making. However, recent moves to strengthen fair trade have created a real need for single-period inventory decision-making problems. This study addresses the problem of ordering quantity decisions that are expected to maximize profits using classical newsvendor models. The research target is data on seasonal and perishable products from retail. We also use data from retailers to actually apply the newsvendor model and calculate the results to compare performance. It also suggests solutions for estimating demand for products sold in order to apply newsvendor models that utilize actual demand ratio versus forecast demand. This study would like to examine the effectiveness of this research through data analysis and make some suggestions for applying it to reality.

Objectives: This study was conducted to analyze the symptoms and care needs of home-based hospice palliative patients in Busan and to provide a basic reference for developing practical guidelines for their care. Methods: By examining the registration cards of 409 hospice palliative patients, who were registered in community health centers in Busan as of 2016, this study retrospectively analyzed their characteristics, symptoms and care needs. Results: The average age was 70.6 years, 59.4% were receiving medical benefits, and 48.4% lived alone. As per the data obtained from the Palliative Performance Scale, many were able to mobile. Fatigue was the most severe and depression and anxiety were reported together, and their care needs were also high. Most subjects reported mild or low pain, but care needs were high. Furthermore, the medical benefits group showed a high level of symptoms and care needs across areas. Conclusions: To help subjects to live in their homes for as long as possible, it is necessary to identify symptoms and care needs and provide services in accordance with their severity and situation. Thus, it is necessary to develop practical guidelines for standardized community hospice palliative care services.
