Purpose: The purpose of this study is, in the situation where rapid response to the rapidly changing environment is required due to the development of the fourth industrial revolution such as artificial intelligence, virtual reality, and the internet of things, robotics, big data, additive manufacturing, bio-health, sharing economy and in the organizational culture aspiring toward the innovation of a major company, small business and a public institution, to analyze what influence a job-engagement and stress make, and what influence individual's self-efficacy as a moderator mediator makes, and to offer basic data for improving job-engagement and lowering job-stress. Research design, data, and methodology: For doing this, the literature and the empirical studies were combined. Deriving innovation-oriented organizational culture as factors affecting the job engagement and job stress through the literature, and have established hypotheses to verify them. We have collected data of 281 from ex,ecutives and staff-members working in areas including major company, small business and officials (the central government, a local public service, the prosecution, the police, and school). And these data were analyzed by SPSS 23 version. Results: Based on these data, the results of analysis were as follows; First, the innovation-oriented organizational culture which was recognized by organizational members had effect on job-stress. Second, the innovation-oriented organizational culture which was recognized by organizational members influenced job-stress. Third, in the relationship between the innovation-oriented organizational culture and job-engagement, self-efficacy did not influenced job-engagement. Finally, in the relationship between the innovation-oriented organizational culture and job-stress, self-efficacy influenced job-stress. Conclusions: Innovation-oriented organizational culture places importance on the organization's adaptability and flexibility in the external environment, so companies need to establish an innovation-oriented organizational culture favorable to achieving survival and successful innovation, and to develop and disseminate programs of positive and continuous organizations to improve task enthusiasm, reduce task stress, and enhance organizational performance. In the future, it will be necessary to verify the effectiveness of various organizational culture types through comparative analysis with companies that actively maintain an innovation-oriented organizational culture (Google, Kakao, etc.) and companies that prefer hierarchy-oriented organizational culture, relationship-oriented organizational culture, and market-oriented organizational culture.

In this paper, we present a knowledge-based object-oriented spatial database system called KOBOS. A knowledge-based approach is introduced to the object-oriented spatial database system for data modeling and approximate query answering. For handling the structure of spatial objects and the approximate spatial operators, we propose three levels of object-oriented data model: (1) a spatial shape model; (2) a spatial object model; (3) an internal description model. We use spatial type abstraction hierarchies(STAHs) to provide the range of the approximate spatial operators. We then propose SOQL, a spatial object-oriented query language. SOQL provides an integrated mechanism for the graphical display of spatial objects and the retrieval of spatial and aspatial objects. To support an efficient hybrid query evaluation, we use the top-down spatial query processing method.

Nowadays an information exchange on XML such as B2B electronic commerce is spreading. Therefore the systematic and stable management mechanism for storing the exchanged Information is needed. For this goal there are many research activities for connection between XML application and relational database. But because XML data have hierarchical structures and relational database can store only flat-structured data, we need to store XML data in object-oriented database that support hierarchical structure. Accordingly the modeling methodology for storing XML data in object-oriented database is needed. In order to build good quality application systems, modeling is an important first step. In 1997, the OMG adopted the UML as its standard modeling language. Since industry has warmly embraced UML, its popularity should become more important in the future. So a design methodology based on UML is need to develop efficiently XML applications. In this paper, we propose a unified design methodology for XML applications based on object- oriented database using UML. To this goal, first we introduce a XML modeling methodology to design W3C XML schema using UML and second we propose data modeling methodology for object-oriented database schema to store efficiently XML data in object-oriented databases.

An object-oriented database was developed as a framesork for integrating into ergonomic interface models data for workplace modelling and ergonomic evaluation functions as well as basic anthropometric data required to construct a man model. In order to develop an ergonomic man model representing operators that interact with his working evnironments, not only anthro- pometric data but also efficient handling of such data and accurate representation of the work- space are needed as a prerequistite to proper ergonomic evaluation. Most existing man models are not, however, capable of fully utilizing these data due to the lack of a generallized formalism of data handling, which results in system performance degradation or a potential difficulty when the system is upgraded. In this research, these three sets of data with distinct characteristics were incorporated into a comon integrated database required to manipulate an ergonomic interface model fully coupled with the man model itself. An object- oriented scheme was sued for the database design Specifically, UniSQL/X, an object-oriented database management system and the X-window system on SPARC workstation were used for implementation. The ergonomic man model generated from the object-oriented database is found to possess great flexibility and performance compared to existing ergonomic interface models or ergonomic CAD systems.

Purpose: This research was, by investigating the relations between the cultural types of a nursing organization in military hospital and performance, to ascertain the cultural types to be able to improve performance. Method: The date were gathered from 255 nurse officers who were in 19 military hospitals by using the self-report type of questionnaire. The period of data collection was from April 20, 2003 to July 15, 2003. For this research, the following tools were used: the tools for measuring the organizational characteristics, organizational culture, and job satisfaction, the tool for measuring organizational commitment. For data analysis the SPSS Win 12.0 program was used. Result: 1) Most of the cultural types of a nursing organization in military hospital is Relation-oriented. 2) In the relation between general the characteristics of subject and the organizational cultural type, there was a difference in the innovation-oriented, relation-oriented, hierarchy-oriented, and task-oriented culture according to nurse officers careers, hospital types, year in hospital, marital status, and unit(p<0.05). 3) In the relation between general characteristics of subject and organizational performance, there was a difference in the job satisfaction, affective commitment, transactional commitment, and normative commitment according to nurse officers careers, education, madrigal status and unit(p<0.05). 4) In the relationship between the of a military hospital were correlated with the type of each culture(p=0.00), 5) In the relation between the organizational culture type of military hospital and its performance, there was a positive correlation among job satisfaction and innovation-oriented culture, relation-oriented culture, task-oriented culture(p<0.05). And hierarchy-oriented culture showed that they had a weak negative correlation with job satisfaction(p<0.05). There was a positive correlation among affective commitment and innovation-oriented culture, relation-oriented culture, task-oriented culture(p<0.05). And hierarchy-oriented culture showed that they had a weak negative correlation with affective commitment(p<0.05). There was no culture type significantly related to continuance commitment and there was a weak positive correlation among normative commitment and innovation-oriented culture, relation-oriented culture, task-oriented culture. The types to have an influence upon nurse officers' job satisfaction were relation-oriented culture and innovation-oriented culture(p=0.00). And relation-oriented culture and innovation-oriented culture were major variances for affective commitment and only relation-oriented culture was influential variance for normative commitment(p=0.00). Conclusion: The organizational culture type was found which had an influence upon nurse officers' job satisfaction and organizational commitment. These result are very significant in having showed the persons in charge of nursing administration a basic data for creation of an effective organizational culture.

The complex documentation involved in power system analysis software require a well-defined and friendly database system. We have developed an object-oriented database management system for power system analysis, and have described load flow analysis and transient stability analysis using object-oriented database(OODB). Database management systems are widely used and achieve high reliability of data management in the engineering fields. However relational database system have shortcomings in application to power system analysis. ill relational database, the data model is too simple for modeling complex data and database languages are very different from programming languages. Object-oriented techniques are sufficiently powerful to support data-modeling requirements of GUI applications. The GUI is implemented using C++ on a MS windows platform. The OODB supports data modeling requirements of GUI applications and the performance is well acceptable for Gill applications.

Data in one Product Model for shipbuilding is inevitably referenced and manipulated during each phase of design or production activities, and data or manipulation status naturally varies from the original with the advance of each activities. For Object-Oriented approach, it is hard to identify classes dealing with those variations, and even if once a product model is developed, it might be getting much harder to modify it to cope with a new additional phase of activities. This paper proposes an Instance-Oriented Modeling Method, temporarily named “Concept-Relationship Modeling Approach”, which handles Data structure and Behavior independently of each other in order to resolve the difficulties above.

This study investigates the perception of price and the propensity to conspicuous consumption in the purchase of clothing among college students and the relation between the perception of price and the propensity to conspicuous consumption. The data for this study were collected from 1,015 Korean college students. In order to analyze the data, statistical methods such as frequency, percentage, mean, standard deviation, factor analysis, ANOVA, scheffe-test, Pearson's correlation, and Cronbach's a were used with the SPSS statistical package program. The major study findings were as follows. 1. The perception of clothing price among college students was classified into five factors: high price-oriented, discount-oriented, high quality-price rate-oriented, low price-oriented, and effectiveness-oriented. 2. The propensity to conspicuous consumption of clothing among college students was classified into four factors: brand name conspicuousness, conspicuous pursuit of vogue, symbol of their social position, and imported goods conspicuousness. 3. High price-oriented and discount-oriented were different significantly according to sex, age, father's educational level, monthly income, monthly allowance amount. High quality-price rate-oriented and low price-oriented were different significantly according to sex, father's educational level, monthly income, monthly allowance amount. Effectiveness-oriented was different significantly according to sex, age. 4. Brand name conspicuousness, conspicuous pursuit of vogue and imported goods conspicuousness were different significantly according to sex, age, father's educational level, monthly income, monthly allowance amount. Symbol of their social position was different significantly according to sex, age, father's educational level, monthly income. 5. High price-oriented, discount-oriented and high quality-price rate-oriented have the highly positive correlation with four factor of propensity to conspicuous consumption of clothing. Low price-oriented has the negative correlation with four factor of propensity to conspicuous consumption of clothing. Effectiveness-oriented has the lowly positive correlation with four factor of propensity to conspicuous consumption of clothing.
