A Process Quality Information System (PQIS) for the CIM environment is presented. The system includes three subsystems which are qualify control, statistical analysis, and information management. As part of CIM, the PQIS was designed by using the ICAM Definition(IDEF) methodology. The Oracle-CDE was utilized as a graphic development tool which made the system more user friendly. PQIS operates on IBM or compatible PCs under MS-Windows and Oracle DBMS. The methodology developed in this research provides a foundation for the application of CIM subsystems.

Quality costs seem to be one of the effective tools to assess quality management activities, but shipping industries have not controlled quality costs because of difficulty in cost itemization and cost data collection. This study has attempted to itemize shipping quality costs in detail and researches the composition of actual quality costs of sampled shipping companies in Korea. Result of research shows that stopping quality costs were composited by 24.3%, 3.8% and 71.8% of prevention costs, appraisal costs and failure costs, respectively and very high relationship between total qualify cost and other quality costs. This research also recommended practical methods for quality management by using indexes of quality costs.

This study defined the notion of general idea on m-learning as based upon e-Learning and mobile internet related literature review and identified the m-Learning distinctive features. Also, this study has searched for factors that are expected to influence the use intended for m-Learning from self-regulated learning, which is acknowledged to be a useful method for learning accomplishment in education field, in order to measure the relationship between learners' motivation and use intention. Then it has empirically validated the conceptual model based on Davis' TAM (Technology Acceptance Model) As a result, self-efficacy, self-determination, interest, contents quality, time management, help seeking, and Peer study are factors affecting Perceived usefulness. Also self-efficacy, self-determination, interest, contents qualify, time management, and peer study are factors affecting perceived ease of use. Finally both perceived usefulness and perceived ease of use are significant factors affecting use intention.

Integrated Supply Chain Management is a important subject for all enterprise activities as include logistics/sales, transfer and storage, manufacturing, purchasing of materials. A recent customer wants to receive high level service of all parts as Qualify, Delivery, Cost and Product. Therefore, Enterprise effort to supply for customers needs use some techniques like Data Mining, POS, MIS. Inventory and Logistics cost is the highest expense of all cost from first supplier to final customer on supply routine. So, SCM's basic purpose is reduce to that cost. So that this paper explain necessary, background, concept of SCM, analyze several using methodology and function of main SCM solution, after propose to ATP model include arithmetic procedure, functions, input data for determines available due date.

This study aims to examine the impact of audit committee characteristics on income management of companies listed on the Stock Exchange of Vietnam. Research data was collected from all 745 listed companies on Vietnam's stock market over four years, from 2015 to 2018. After excluding companies that did not qualify, there were 216 companies with 864 observations. With the help of dedicated software Stata 15, the impact of audit committee characteristics (through independent variables and control variables such as Audit Committee Independence, Auditing Committee size, Auditing Committee Expertise, Auditing Committee Meeting Frequency, Company Size, Financial Leverage, and Operating Cash Flow) to earning management through a multivariate regression model was determined. Research results from Vietnamese listed companies during this period show that the size and expertise of the audit committee are inversely related to the discretionary accruals representing earning management. At the same time, the research results also identify a positive relationship between firm size and earning management, and the inverse relationship between financial leverage, net cash flow from operating operations and earning management. However, the multivariate regression results do not find clear evidence of a relationship between audit committee independence and the audit committee meeting frequency to earning management.

국내의 경우 2000년 이후부터 건설교통부의 지원 하에 건축/토목/메카트로닉스 전문가 집단을 중심으로 경쟁력 있는 건설자동화 기계들이 개발되어 현장에 시험 적용되어 왔다. 개발완료된 자동화 기계의 성능을 분석하여 재래식 방식과 비교한 자동화 방식의 효율성을 제시하기 위한 연구가 수행되었으나 자동화 기계 연구개발 과정에서 요구되는 성능 분석을 체계적으로 수행하지 못하였다. 또한 자동화 기계 개발의 중요한 목적의 일부인 안전성 및 품질 향상 정도에 대해서 정성적으로만 기술함으로써 자동화 기계 개발의 종합적 가치 분석이 수행되지 못한 점은 문제점으로 지적되어 왔다. 따라서 본 연구에서는 자동화 기계 연구개발 단계를 타당성 분석 단계/제작 단계/실용화 및 마케팅 단계로 구분하고 각 단계에서 요구되는 건설자동화 기계의 성능 분석을 효율적으로 수행할 수 있도록 성능 분석 절차 및 방법론의 제시를 통해 건설자동화 기계의 종합적 성능 분석 모델 및 시스템을 개발하였다. 본 연구를 통해 제안된 성능 분석 모델 및 시스템의 활용을 통해 건설자동화 기계 개발 타당성 분석 및 현장의 요구사항을 만족시키는 우수한 성능을 지닌 자동화 기계를 개발할 수 있으며, 개발된 자동화 기계의 마케팅 전략을 효과적으로 수립할 수 있도록 함으로써 건설자동화 기계의 확대 보급 및 실용화에 기여할 수 있을 것으로 기대된다.

It is required to study systematical on the concrete quality management to extend structure life because rebuilding effect is reducing under present condition of large sized and high stories structure. Concrete, which shows its intensity by hydrating action and a big change in quality according to hot weather and temperature, produces a lot of qualify problem under hot and cold weather Because of each specification and construction plan which does not have basic standard on site, concrete's quality is irregular and makes some defect. As a result, Daegu is turned out to be the longest area after investigating application period and days focused on 8 cities weather information about relationship between hot weather circumstance and construction environment. Therefore, we first surveyed the concrete material in the region and found out the problem of quality nanagement. Then figure out the way of solution. Moreover, we integrated concrete material quality management, which is applied differently to each site, to have equal quality and to reduce defect from construction site. And then, based on various test of construction condition and analysis of quality management item, we suggest effective concrete quality management to make concrete material construction standard guide and plan under hot weather.

The purpose of this research is to suggest the promotive directions of Quality Circle activity. Since 1975, variety of organizations in Korea have widely the implemented Quality Circle activities for their management systems. Today, Companies are facing the harsh realities of a competitive environment. This is no time for revolutionary change. Instead, Companies are instituting revolutionary change meant to have impact within a very short time frame. The Worker's Quality Circle activity is, essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. The industries have enthusiastically used Quality Circle activities and were influenced from them. The Quality Circle activities can be regarded as a kind of Knowledge Management where new knowledge is created and knowledge is shared in the economy. However, the academics were less interested in this subject, as a result, there were no systematic guidances for Quality Circle activities. Also, the government was less interested in these activities, as a result, there were no systematic policy making for Quality Circle activities. Thus, in this research, the promotive directions for Quality Circle activities were suggested which were based on the results of survey Questionnaires presented to promoters of the domestic companies. As a results of this research, to maximize the effect of TQM(Total Quality Management) in the nationwide, Quality Circle activity as a bottom-up management should be more expanded and revitalized.
