Traditionally, information systems audit has been carried out by the auditors. So the main focuses of audit are managerial point of view, such as finding errors or missing functions. The final purpose of audit, however, is to help the organization to make better decision through better information services. So we felt that managerial point of audit should be extended to include the factors that increase the competitiveness of organization. To accomplish this goal, new factors that reflect the ideas of three groups, users, developers in addition to auditors. First, by adopting the ideas from service quality evaluation area, we develop six items and 24 indexes for information systems audit. Second, we separate the audit related parties into three groups, users, developers and auditors. The main reason is that major concerns of three groups to the system will be different considerably. Third, we quantified the weights of each group to each 6 items and 24 indexes using Analytic Hierarchy Process. Fourth, the resulting weights of each item are found to be different by the group, and possible reasons are analyzed.

Six sigma is a management innovation strategy which improves all managerial processes in an integrated manner, Six sigma can be applied to every aspect of managerial functions such as marketing, engineering, purchasing, accounting, and so on. Six sigma is trying to solve quality problems from the customer's viewpoint in the scientific manner, thus maximizing profits through the elimination of quality costs. This paper is presented to verify empirically the successful factors of implementing six sigma through the survey of black­belts of Korean firms. The blue­chip companies in Korea and across the world have already adopted Six Sigma, and it is becoming an integral part of the corporate culture of these companies. In conclusion, the most important factors to the success of six sigma are found to be the leadership of top management, and the compensation/ incentive system. The analysis also shows that the important factors are different in terms of both the process type and implementing stage.

Soils in the sloping uplands in Korea are subject to intensive land use with high input of agrochemicals and are vulnerable to soil erosion. Development of the environmentally sound land management strategy is essential for a sustainable production system in the sloping upland. This report addresses the status of upland agriculture and the best management practices for the uplands toward the sustainable agriculture. More than 60% of Korean lands are forest and only 21% are cultivating paddy and upland. Uplands are about 7% of the total lands and about 62% of the uplands are in the slopes higher than 7%. Due to the site-specificity of the upland, many managerial and environmental problems are occurring, such as severe erosion, shallow surface soils with rocky fragments, and loadings of non-point source (NPS) contaminants into the watershed. Based on the field trials, most of the sloping uplands were classified as Suitability Class III-V and the major limiting factor was slope and rock fragments. Due to this, soils were over-applied with N fertilizer, even though N rate was the recommendation. This resulted in decreases in yield, degradation of soil quality and increases in N loading to the leachate. Various case studies drew management practices toward sustainable production systems. The suggested BMP on the managerial, vegetative, and structural options were to practice buffer strips along the edges of fields and streams, winter cover crop, contour and mulching farming, detention weir, diversion drains, grassed waterway, and slope arrangement. With these options, conservation effects such as reductions in raindrop impact, flow velocity, runoff and sediment loss, and rill and gully erosion were observed. The proper management practice is a key element of the conservation of the soil and water in the sloping upland.

It is very important for the competitiveness and sustainable management of enterprises that the rapid changes in the managerial environments quickly and accurately are responded. For example, the large-scale investment accompanied by bad alternatives in accordance with misunderstanding of the managerial environments yields the huge cost and effort to modify and improve. In firm management, the quality of products and the productivity are influenced by changes of the endogenous factors yielded in manufacturing process and the exogenous factors as market, etc. These changes include not only changes in 4M (man, machine, material, method) but also those in the market, competitors, and technologies in the process of commodification, i.e., first, such disturbances make dispersion of the process big and odd. By Shewhart chart it can be checked that the process monitored is control-in or out. Business administration executes activities for input stabilization by monitoring changes in 4Ms, comparing with the standards, and taking measures for any abnormality. Second, TRM (technology road map) is to prospect product deployment and technological trend by predicting technologies in the competitive environment as the market, and to suggest the future directions of business. So, TRM must be modified and improved according to DR (design review) stages and changes in mass-production like input material change. Therefore, a role of TRM in input stabilization for reducing cost and man-hour is important. This study purposed to suggest that the environment changes are classified into endogenous factors and exogenous factors in production process, and then, quality and productivity should be stabilized efficiently through connection between TRM and input stabilization, and to prove that it is more effective for the display industry to connect TRM with input stabilization rather than to use TRM separately.

Stakeholder management in construction projects is an important factor in project performance creation. The purpose of this study is to verify the effect of the recognition of the importance of the quality influence factors among the stakeholders of the construction project on the perceived quality and the project performance. The impact of the project management methodology on the project performance has been actively researched, but there is little research result on the project stakeholders. The projects to be researched are apartments and buildings that have been completed within the last five years of domestic large construction company. The method of survey is to measure the consensus of the importance of the quality influential factors among the three parties such as the ordering party, the design supervisor and the constructor, and confirm whether the agreement affects the quality of the actual project. Finally, the research model was verified by surveying the satisfaction of the client on the final product. The results are as follow. The degree of agreement on the importance of quality influential factors among stakeholders has a significant effect on perceived quality. In the relationship between perceived quality of influence factors, organizational (support) quality influenced technological quality and managerial quality, and technological quality and managerial quality also have significant influence on resource quality. The results of analysis showed that perceived quality of resources strongly influenced project performance. The remaining three experienced qualities also significantly affect project performance.

The purpose of this study was to analyse the factors that influence marital conflicts and family life statisfaction, and to predict the future stage of establishment family and extending family, bsed on the theretical model by system approach. For this pourpose, 336 couples of urban households in Seoul were selected. The data were analysed through statistical methods such as, Frequency, percentile, T-test, F-test, ANOVA, Pearson's correlation analysis. The results were as follow : The Martial Conflict and family life satisfaction of surveyed couples were above middle level. It had significantly differences according to family life cycle, husband and wife's educationed levels, husband and wife's occupations, and family income. And Family life satisfaction had significantly differences according to marital conflict. The marital conflict is higher, life satisfaction is lower. In this study, it were appeared that the amount of marital conflict and life satisfaction had differences according to life cycle stages, husband and wife's educational level, husband and wife occupations, and family income, and so that the conflict of phsycho-social system was more affected on family life satisfaction that of managerial system. Such results were indicated that the birth of children was the critical family event affecting on family life satisfaction on and the marital conflict. But the conflict by family's given resources and situational differences also as an environment affection on the family system.

As the role that information system and technique plays in hotel firms is critical, the quality of IS and IT is considered as one of most important factors that determine success of hotel firms. This study aims to examine the influences of the quality of IS/IT exerted on the user's level of acceptance of the HIS and the operational performance on both personal and organizational levels. Based on the data collected from 256 employees in reservation departments of 3 Seoul and 3 Busan deluxe hotels, the study tested the applied TAM model. The results indicated that the quality of IS/IT affects the user's acceptance level (eg., satisfaction and perceived usefulness), and such acceptance behavior affects reservation employees' performance on both personal and organizational levels. Managerial implications are also presented for researchers and practitioners of hotel firms.

Many enterprises are interested in using the IS development methodologies as a means of increasing system performance and solving the problems of delayed delivery time, excessive budget, and failure of integrated systems. Even if previous researches showed that the system productivity and quality improvement using the system development methodologies are very poor, we tried to find that the methodologies are meaningful as an innovative means for IS performance. We defined that the IS development methodology as a technical and managerial innovation for IS department. We intended to study the relationship between the implementation process of the IS development methodology divided into four steps and IS performance. A cross-sectional field survey with IS departments of domestic companies was conducted, and we used LISREL 8.12a to perform the structural equation model analysis and hypothesis verification. We found the meaningful relationship between the development methodology and qualitative performance. We reconfirmed that the relationship between the development methodology and quantitative performance is not meaningful as expected, which is the same result with the previous researches. But the qualitative performance affects very strongly to the quantitative performance. As a results, we suggest that IS managers and developers keep the principles of the IS development methodologies to get the quantitative performance through the qualitative performance improvement.

Purpose: The public sectors including government and public organizations have put an efforts to improve the quality of people's lives by providing enhanced services. The purpose of this paper is to investigate the factors that affect job attitude, job satisfaction, and job performance in the public sector, that are rarely examined by previous studies. Research Design, data, and methodology: The following research questions have been proposed: i) how do payroll system, personnel management system, cooperative working environment, and self-efficacy affect job attitude?; and ii) how does job attitude affect job satisfaction and performance? This paper used a survey through an online platform and collected data randomly from five classified public institutions. This study applied regression analysis and ANOVA. Results: This study found that cooperative working environment and self-efficacy had significant impacts on job attitude, while payroll system and personnel management system did not affect job attitude. Overall job attitude affected both job satisfaction and performance. Conclusions: The results provide policy implications to the public sector which factors should be considered to improve job attitude, job satisfaction, and job performance. The results also provide managerial implications how such efforts ultimately improve service quality to the citizens.

A more interactive teaching-learning system is increasingly necessary in the consumer-oriented environment of distance education. This article would like to suggest a more spontaneous system which is learners at various levels. The suggested system keynotes its efficiency with the introduction of a "mobile agent" concept through which learners are able to network and complete their assignments despite their dispersed environments. This article also suggests some managerial techniques for the systematic management of agent-based learners possessing diverse characteristics. Through this study, we expect more highly effect by offer data adapted to learning goal to learner's ability, get out of uniform web-based teaching-learning.
