The challenge is to maximize the time-to-market benefits of concurrent engineering while maintaining control of data and distributing it automatically to the people who need it when they need it. The way PDM systems cope with this challenge is that master data is held only once in a secure vault where its integrity can be assured and all changes to it monitored, controlled and recorded. The structure of PDM is various from vendor, but they have common module. That is PDM and it is most important. The goal is to design the workflow in PDM using object-oriented modeling method. The past methods have concentrated on the flow between workflow engine and agent, but this paper will focus on task. We will model task as individual object. This paper uses OMT(Object Modeling Technique) by James Rumbaugh for base modeling tool and uses DCOM(Distributed Component Object Model) for base ORB(Object Request Broker). Research object is to design the static object model, to design state change by dynamic model and to design data transition by functional model.

This study analysis the effects of the relationship between LMX and affiliation-OCB, challenge-OCB which is voluntary behavior of organizational members. For this study, the effect of LMX on AOCB and COCB, as well as the mediating effect of AOCB behavior, the moderating role of toxic leadership, were analyzed. The results of studies are as follows. First, LMX had a positive effect on AOCB and COCB, respectively. Second, AOCB has a mediating-effect between LMX and COCB. and Third, toxic leadership confirmed the moderating-effect between LMX and AOCB, and finally the moderated-mediating-effect through AOCB in the relationship between LMX and COCB. Therefore, it was analyzed that the quality of the relationship between leader and member in the organization is an important factor in expanding the positive and voluntary behavior of members in the organization. In addition, since toxic leadership weakens positive and voluntary civic behavior for organizational members, it suggests the need for strategy to overcome toxic leadership for an efficient organization management.

This study aimed at investigating the effects of sub-variables of elderly people's lifestyle health and leisure oriented pursuits, outdoor and challenge pursuits, security and material pursuits, family oriented pursuits, and peer oriented pursuits on what they perceive to be successful later years. The background of this study was that there has been few study on the older population in Korea with focus on their cultural and traditional norms. The objective of this study was to investigate the effects of elderly people's lifestyle on what they perceive to be successful later years, thereby identifying practical implications for better social welfare associated with successful later years. Analysis was carried out of self reported questionnaires and self-interviews with elderly people aged over 65 frequenting a welfare center for elders and a community center in a city in Korea. In order to examine the effects, a reliability test, a descriptive analysis, a correlation analysis, and a multi-regression analysis were performed. The results of the analysis for sub-variables of lifestyle showed that health and leisure oriented pursuits, outdoor and challenge pursuits, security and material pursuits, family oriented pursuits, and peer oriented pursuits had significant positive impact on successful later years. The two most influential were peer oriented and family oriented pursuits. Drawing on the results, this study suggests that what is needed for dejected and lonely elderly members in the society is to provide them with opportunities for developing and keeping good relationships with friends and family members and there is a need for a system where old people, as consumers of cultural capital, can have easy access to a variety of cultural resources and activities at a local and regional level.

In this paper, teaching object-oriented design in a programming course is a big challenge for instructors. "Objects-first" is a popular strategy for teaching object-oriented programming in the educational settings, by introducing the concepts of objects, classes, and instances before procedural elements of a programming language. Still, this approach emphasizes coding rather than other critical aspects of software development, notably problem-solving and design. We propose a "design-first" approach, which subsumes an objects-first approach into lessons that also introduce object-oriented analysis and design, using elements of UML before implementing any code. We also present video rental store (SRS) that uses the design-first approach to help students of various teaming styles in a software engineering course. It interfaces with an IDE we have chosen specifically to support the design-first approach, and SRS which has been shown to be effective in helping students learn object-oriented programming concepts.

"Personalized medicine," the goal of which is to provide better clinical care by applying patient's own genomic information to their health care is a global challenge for the $21^{st}$ century "genomic era." This is especially true in Korea, where provisions for clinical genetic services are inadequate for the existing demand, let alone future demands. Genomics-based knowledge and tools make it possible to approach each patient as a unique biological individual, which has led to a paradigm-shift in medical practice, giving it more of a predictive focus as compared with current treatment oriented approach. With recent advancements in genomics, many genetic tests, such as susceptibility genetic tests, have been developed for both rare single gene diseases and more common multifactorial diseases. Indeed, genetic tests for presymtomatic individuals and genetic tests for drug response have become widely available, and personalized medicine will face the challenge of assisting patients who use such tests to make appropriate and wise use of genetic risk assessment. A major challenge of genomic medicine lies in understanding and communicating disease risk in order to facilitate and support patients and their families in making informed decisions. Establishment of a health care system with provisions for genetic counseling as an integral part of health care service, in addition to genomic literacy of health care providers, is vital to meet this growing challenge. Realization of the promise of personalized medicine in the era of genomics for improvement of health care is dependent on further development of next generation sequencing technology and affordable sequencing test costs. Also necessary will be policy development concerning the ethical, legal and social issues of genomic medicine and an educated and ready medical community with clinical practice guidelines for genetic counseling and genetic testing.

Lifestyle is an important variable to understand consumer behavior because it is a lifestyle that is common to all members of society or some members of society. so In this study, the survey has been performed on adult mobile game users over the age of 20 in Korea and China to evaluate the correlation between lifestyle and will of continuous use of game by mobile game users, and the hierarchical multiple regression analysis has been performed on the collected data by using the statistical package program SPSS 20.0. There were total 212 respondents with the gender ratio of 50:50, and 107 respondents were Korean, and 105 respondents were Chinese. As a result of study, first, regardless of lifestyle, more male and more Chinese respondents showed higher will of continuous use. Second, among mobile game user lifestyles, the challenge-oriented, trend-oriented, conservative, and ostentatious lifestyles could become significant causal variables for the will of continuous use of game. Yet, the influence of such lifestyle was not correlated with individual genders or nationalities. The result of this study will be provided as the basic data to establish the strategic solution for companies and government policies for entrance into the mobile game market of China in the future.

Expressing complex query conditions in a concise and intuitive way has been a challenge in the design of visual object-oriented query languages. We propose a visual query language called VOQL (Visual Object oriented Query Language) for object oriented databases. By employing the visual notation of graph and Venn diagram, the database schema and the advanced features of object oriented queries such as multi-valued path expressions and quantifiers can be represented in a simple way. VOQL has such good features as simple and intuitive syntax, well-defined semantics, and excellent expressive power of object-oriented queries compared with previous visual object-oriented query languages.
