Enterprise resource planning(ERP) in nature entails large scale business process redesigns and the corresponding risks. To reduce such risks, enterprise modeling(EM) approach could be adopted through which ERP is planned and effectively implemented on a consistent basis throughout the entire organization. The scope of this paper is to report on EM experiences and lessons learned in the process of ERP implementation. Through a case study, this paper presents and EM methodology which takes due account of strategic business processes, information flows, organizational requirements, and their interdependencies. To assess the impact of distributed application scenarios on effective ERP implementation, alternative EMs have been created and evaluated whether they support information requirements for strategic decisions and day-to-day operational activities, core business processes, and business functions as required. Practical issues and problems raised in the EM process have been discussed.

This study has been started in order to provide basic information for the planning of Korean elderly care facilities by analysing For-profit elderly homes of Japan. Japan is famous for her high elderly proportion and also her fast aging speed. Therefore, Japanese experiences of trials and errors related to the supply of elderly homes will be a good guideline for Korea which is undergoing the sharp increase in elderly population. Data have been mainly collected from the official statistics of Japan and Korea. The outcomes of this study are as follows. At first, the definition of For-profit elderly homes of Japan has been proposed clearly. Secondly, the trends of them related to supply and operational characteristics have been analysed. Thirdly, the size and utilization rate of them have been analysed. And finally, the physical characteristics of elderly residences in For-profit elderly homes of Japan have been discussed.

Recently, multiple criteria decision making has been well established as a practical approach to seek a satisfactory solution to a decision making problem. Goal programming is one of the most powerful MCDM tools with satisfying operational assumptions that reflect the actual decision making process in real-world situations. In this paper we propose an efficient method implemented on a microcomputer for solving linear goal programming problems. It is an iterative revised goal simplex method using the sparsity technique. We design as interactive software package for microcomputers based on this method. From some computational experiences, we can state that the revised iterative goal simplex method using the sparsity technique is the most efficient one for microcomputer for solving goal programming problems.

Noting that compatibility beliefs are important antecedents of technology adoption, the objective of this study was to assess compatibility beliefs that affect users' intention to adopt a mobile entertainment service (MES). We developed a set of key compatibility beliefs: compatibility with life-style, compatibility with social meaning, and compatibility with past flow experiences. We then defined the key dimensions of each construct and developed operational measures for those dimensions. We tested the theorized effects of each of the compatibility constructs on MES adoption. The results support the effects of compatibility beliefs on users' intentions to adopt MES.

Recent years have shown great advances in the feasibility of long subsea tunnels. Projects such as the Channel Tunnel, the Stoerebelt Tunnel or the Bosporus Crossing have pushed the boundaries of TBM tunneling technology and fueled the work on feasibility studies for even more challenging projects such as crossing the Qiongzhou or Gibraltar Straits. There are numerous geotechnical challenges such as wide variations of ground conditions, high operation pressures or long tunnel distances and finally geological uncertainties which must be solved in order to attempt such projects. Several operational challenges such as large muck quantities interventions under difficult conditions and long transport distances also have to be tackled. TBM manufacturer and construction industry have developed a number of approaches to these challenges which point into the right technical direction and have been proven successfully in recent experiences. Their further development will allow attempting several megaprojects which are currently under discussion.

This paper deals with the topical problems of the Life Cycle Costs in connection with the rolling stocks. the LCC philosophy has already entered the third decade. this philosophy contributed towards the new relationship's comprehension between railway vehicle producers' and railway vehicle users' sphere. this leads together to the technical-economical solution convenient for the both sides. In the point of manufacturer, It is said that low operational costs could be reached using a well-designed and structured maintenance program. this is due to the proper technical analysis of critical components that leads to low costs of maintenance and a superior reliability without increasing the capital investment. but, This paper presents both topical experiences with the LCC models for the railways vehicles and also procedures during Life Cycle Costs calculations. In conclusion I want to introduce how to calculate LCC & what kinds of softwares are used based on VVVF EMU vehicle

This article aims to analyze the experience of designing and operating a class model linking undergraduate and graduate students in engineering education and suggest its development direction. To achieve these objectives, the undergraduate-graduate linked class model was applied to community problem-solving education and a case was analyzed. It also specifically presented the process of how we design the class model and what the actual operational performances and improvements are. This study found that undergraduate and graduate students could build integrated and horizontal cooperative relationships in their classes through undergraduate-graduate linked education and, particularly, graduate students could gain meaningful educational experiences. However, it was difficult to obtain tangible performances through the team activities of these students within a semester. In order for engineering colleges to operate undergraduate-graduate linked education, it would be necessary to provide a longer and more systematic educational environment and better curriculum. The study tried to seek specific tasks and ways to improve them.

This article examines the consequences of a significant spent fuel management decision or event in the United States, South Korea and Taiwan. For the United States, it is the financial impact of the Department of Energy's inability to take possession of spent fuel from commercial nuclear power companies beginning in 1998 as directed by Congress. For South Korea, it is the potential financial and socioeconomic impact of the successful construction, licensing and operation of a low and intermediate level waste disposal facility on the siting of a spent fuel/high level waste repository. For Taiwan, it is the operational impact of the Kuosheng 1 reactor running out of space in its spent fuel pool. From these, it draws six broad lessons other countries new to, or preparing for, nuclear energy production might take from these experiences. These include conservative planning, treating the back-end of the fuel cycle holistically and building trust through a step-by-step approach to waste disposal.

The purpose of this study is to investigate the influences of Science Core schools on students' positive experiences about science (PES) through in-depth interviews with teachers in charge of science core schools. In-depth interviews with teachers were conducted to explore the factors that led to the effectiveness of science core schools in improving the student's PES in light of operational characteristics of science core schools as leading schools, characteristic factors of science core schools on students PES, and improvement plans and requirements of science core schools as leading schools, as well as implications for general high schools. In the case of science core schools, the teacher's enthusiasm for science teaching encouraged students' participation in science classes, promoted students' interest in science other than science-core classes, improved students' inquiry and research skills, increased students' competencies such as communications and collaboration by improving science instructions, and affected career search and exploration based on interests in science experiences. Based on the results, ways to spread the characteristics of science core schools to general schools' curriculum implementation are suggested including providing opportunities to experience the value of science study, to experience science and engineering careers through senior students, to participate in team projects and self-regulated science inquires, and so on.

Purpose: The purpose of this paper is to identify a theoretical basis of end-of-life care by examining attributes of the concept of the nurses' acceptance of patient deaths. Methods: Walker and Avant's approach to concept analysis was used. A literature study was performed to check the usage of the concept. To identify the attributes of the concept and come up with an operational definition, we analyzed 16 qualitative studies on nurses' experiences of death of patients, published in a national science magazine from 1999 to 2015. Results: The nurses' acceptance of death of patients was identified as having four attributes: acceptance through mourning, attaining insight on life and death while ruminating life, facing with fortitude and practicing human dignity. Antecedents of the concept were experiences of patient's death, confusion and conflict, negative emotions, passive responses, denial of patients' death. The consequences of the concept were found as the holistic end-of-life care and active pursuit of life. Conclusion: This study on the attributes of the concept of the nurses' acceptance of death of patients and it's operational definition will likely lay the foundation for applicable end-of-life care mediations and theoretical development.
