Due to the limitation of data modeling power and the view update ambiguity, relational view is limitedly used for engineering applications. On the contrary, object-oriented database view would playa vital role in defining custom interface for engineering applications because the above two limitations of the relational view are overcome by the object-oriented view. Above all, engineering application data interface should fully support updates. More specifically, updates against the data interface needs to be unambiguously defined and its semantic behavior should be equal to base schema updates'. For this purpose, we define the notion of update semantic preserving which means that view updates displays the same semantics as base schema. Besides, in order to show the feasibility of this characteristics, specific and concrete algorithms for update preserving updates are presented for a CAD specialized object-oriented database view - MultiView. This paper finds that in order that virtual classes coudld form a schema with 'isa' relationships rather than just a group of classes, the update semantics on the virtual classes should be defined such that the implied meaning of 'isa' relationships between classes are not to be violated. Besides, as its sufficiency conditions, we derived the update semantics and schema constituable conditions of the virtual classes that make view schemas look like base schemas. To my best knowledge, this is the first research that presents the sufficiency conditions by which we could defined object-oriented views as integrated schemas rather than as separate classes.

The present study is aimed to investigate on the moderation of self-rated political skill on the relationships between perceived co-workers' politics and outcome variables (OCB toward co-workers and turnover intention). The used data for analysis was collected from 375 employees who have worked for public and private companies located in Jeju. The results are as follows. First, the main impacts of perceived co-workers politics(PCP) on OCB-C was not statistically significant, whereas the relation of PCP to turnover was positively significant. Second, moderating effects by political skill in the relationship perceived co-workers' politics and OCB-C was not significant, but the moderation in the relation perceived co-workers' politics-to-turnover intention was supported. Implications of the current study are 1) the casual effects of politics on OCB was demonstrated, in particular, the results of previous studies which was not consistent to account for the impact of politics on OCB was proved by the differentiation of research target. The result will help to understand perceived politics. In addition, moderation of political skill in the relation perceived co-workers' politics-to-turnover intention will contribute to expand researcher area of political skill.

This research aimed to investigate the relations of perfectionism and multicultural attitude upon a premise that sub-factors of the perfectionism : self-oriented perfectionism, other-oriented perfectionism and socially-prescribed perfectionism are related to multicultural attitude and to examine the moderation effect of self-acceptance on the relation between perfectionism and multicultural attitude. The questionnaires designed to measure multidimensional perfectionism, unconditional self-acceptance and multicultural attitude were administered to 258 office workers in Seoul and Gyeoggi-Do. The results from correlation analysis and regression analysis were as followed. First, sub-factors of the perfectionism was partially associated with sub-factors of multicultural attitude. In particular two sub-factors of the perfectionism : 'self-oriented perfectionism', 'other-oriented perfectionism' yielded effect on multicultural attitude, controlling the effects of other subscales. Second, unconditional self-acceptance moderated the relation between 'self oriented perfectionism' and sub-factor of the multicultural attitude : 'recognizing difference'. And unconditional self-acceptance moderated the relation between 'socially prescribed perfectionism' and sub-factors of the multicultural attitude : 'recognizing difference', 'openness and acceptance'. This present findings not only extend understandings about relationship between perfectionism and multicultural attitude by examining self-concept : unconditional self-acceptance but also provide that it isn't helpful that further support and rationale for unconditional self-acceptance as intervention for targets to focus in counseling process for those who suffer from perfectionism.

Reuse of software is the process of developing software system which does not develop all modules newly but construct system by using existing software modules. Object oriented concept introduces dynamic binding and polymorphism, which increases number of executable Paths. In this case static analysis of source code is not useful to find executable path. These concepts occur new Problems in retesting. Tradition testing method can not cover complex relations such as inheritance, message Passing and instance of and can not apply on object oriented retesting. we propose the method to reduce the number of methods and classes to be retested in associated class relation.

Service-Oriented Architecture (SOA) is a development paradigm for reusing services as an independent reuse unit. A service delivers a cohesive functionality through its external interface. Since services have unique characteristics which are not typically presented in conventional development approaches, there is a demand for effective approaches to developing services. Most of the current SOA methodologies presenta process where services are designed and developed from the requirements rather than reusing existing assets, which demands high cost and effort. Hence, a desirable approach is to be able to develop services by migrating from their existing legacy systems such as object-oriented system. A difficulty in this migration is that objects in object-oriented systems reveal characteristics which differ considerably from those of services. That is, objects are designed without considering commonalities among several consumers. In this paper, we first define mapping relationships between key artifacts in object-oriented system and those in SOA services. By these relationships and considering commonalities among several applications in a domain, we propose three systematic methods to migrate from object-oriented system to SOA services. Each method consists of a list of input and output artifacts and detailed guidelines which are performed in order. Through these methods, service developers can easily develop services with less effort.

This study divides organizational citizenship behaviors into two dimensions, organizational and individual, in order to clarify the out-role behaviors of organizational members more specifically. In addition, we selected Empowering leadership as an input factor that can lead to organizational citizenship behavior and examined the mediating role of trust. To accomplish this purpose, the authors conducted a survey of employees in manufacturing companies in the Daegu-Gyeongbuk region and the hypothesis was verified through structural equations model. The results of the study are as follows. Empowering leadership has a significant positive impact on OCB-O and OCB-I. Also, Trust has been found to partial mediate effect the relationship between empowering leadership and OCB_O and OCB_I. The results of this study will be specific guidelines for inducing organizational citizenship behavior in organizations, and will further expand the scope of research into organizational citizenship behavior.
