유방자가검진 실천율 및 관련 요인을 규명하여 유방자가검진 실천율을 증가시키기 위하여 고령군 11개 동에 30세 이상 여성 568명을 대상으로 설문조사를 실시하였다. 유방자가검진 실천율은 28.2%이었으며 한 달에 1번 이상 실천하는 사람은 9.7%로 나타났다. 유방자가검진 실천율은 연령, 배우자 유무, 교육 수준, 직업, 경제상태, 흡연, 규칙적인 운동, 만성 질환에서 유의한 차이가 있었는데, 연령별로는 40-49세가 가장 높았고 60세이상이 가장 낮았으며, 배우자가 있을수록, 교육수준이 높을수록 높았다. 직업은 사무 관리직에서 57.1%로 가장 높았으며, 경제상태가 높을수록, 흡연을 하지 않는 경우, 규칙적 운동을 하는 경우, 만성질환에 이환되어 있지 않는 경우, 유방암 가족력이 있는 경우에서 유방자가검진 실천율이 높게 나타났다. 유방자가검진 실천 동기는 건강상의 이유로 스스로 결정한다가 가장 많았으며, 대중매체의 영향, 보건소 홍보 순으로 나타났다. 유방자가검진 미실천 이유에서는 필요성을 못 느껴서가 가장 많았으며, 어떻게 하는지 몰라서, 검사자체를 몰라서 순으로 나타났다. 유방자가검진 여부를 종속변수로 한 다중로지스틱 회귀분석 결과 60세 이상 연령, 교육 수준이 낮을수록, 유방조영술을 시행하지 않는 경우가 유방자가검진 실천율이 낮게 나타났다. 결론적으로 연령이 높고 교육수준이 낮은 농촌 지역의 유방자가검진 실천율과 주기적 검진 실천율은 각각 28.2%와 9.7%로 매우 낮았다. 따라서 보건소를 통한 바람직한 유방자가검진 방법의 홍보 및 보건교육의 강화가 시급하다. 대중매체의 발달로 대중매체를 활용한 홍보 및 보건교육을 실시함으로써 효과를 높일 수 있으며 유방자가검진 교실을 활성화하는 동시에 교육시 대상자가 실제로 실습을 할 수 있도록 함으로써 효과를 높일 수 있을 것이다. 이러한 노력들을 통해서 유방자가검진 실천율을 향상시킨다면 농촌지역 여성들의 건강증진 및 삶의 질 향상에 기여할 수 있으리라 생각한다.

Data envelopment analysis (DEA) has proven to be a useful tool for assessing efficiency or productivity of organizations which is of vital practical importance in managerial decision making. While DEA assumes exact input and output data, the development of imprecise DEA (IDEA) broadens the scope of applications to efficiency evaluations involving imprecise information which implies various forms of ordinal and bounded data possibly or often occurring in practice. The primary purpose of this article is to characterize the variable efficiency in IDEA. Since DEA describes a pair of primal and dual models, also called envelopment and multiplier models, we can basically consider two IDEA models: One incorporates imprecise data into envelopment model and the other includes the same imprecise data in multiplier model. The issues of rising importance are thus the relationships between the two models and how to solve them. The groundwork we will make includes a duality study which makes it possible to characterize the efficiency solutions from the two models. This also relates to why we take into account the variable efficiency and its bounds in IDEA that some of the published IDEA studies have made. We also present computational aspects of the efficiency bounds and how to interpret the efficiency solutions.

Research on employee commitment to the organization is necessary for human resource management, and the result is applied in practice to improve organizational effectiveness. The aim of the present study is to explore factors affecting organizational commitment at the small and medium-sized enterprises (SMEs) in Vietnam. Besides, the relationship between organizational commitment and job performance is examined as well. The research was conducted on a sample consisting of 67 white-collar workers and 260 blue-collar workers at SMEs. A total of 327 valid complete questionnaires were input into SPSS 20 database for processing to provide evidence. The research model and hypotheses were tested using the technique of the hierarchical multiple regression analysis. The research resultsrevealed that income, reward and welfare, direct manager, working environment, coworker, and promotion opportunity tended to associate positively with organizational commitment. Besides, the finding also showed that, when the employee has a high organizational commitment, it would lead to high job performance. The main findings of this study provided some managerial implications for SMEs, in general, and managers, in particular. It implies that Vietnam's small and medium-sized enterprises should improve these six factors to retain employees as well as enhance their job performance.

Customer satisfaction becomes one of the important managerial concerns associated with corporate competency in current competitive environment for Internet communication service companies. Hence, it is demanding to improve a company's customer satisfaction through the total quality management perspective. In practice, engineers as well as the management hope to find major quality characteristics with Internet communication network that is closely related to customer satisfaction, consequently aiming to the raise of their company's customer satisfaction. This paper presents an empirical relationship analysis between network quality characteristics and customer satisfaction on Internet communication. Methodologically, the relationship analysis framework is based on the regression variable selection procedures. In this framework, it is implemented that; 1) iterative model building; and 2) consistent criteria application to statistical tests for selecting significant variables. A case study shows that; 1) the customer satisfaction on the network connection seems to be more closely related to the network quality characteristics compared with the customer satisfaction on the network speed; and 2) the download disconnection rate has relatively evident relationship with the customer satisfaction on the network connection.

The first national QC Circle Convention sponsored by Industry Advancement Administration in 1975 was the beginning of employees group activity from a national point of view. Subsequently some events such as the firs Nationwide Factory Seamaul activity small Group Convention, which was supervised by the ministry of Trading and Industry and Factory Seamaulundong promotion Center, paved the way for proliferation of the group activity through all kinds of manufacturing. Although since November 1982 these two conventions has been united, many problems have been disclosed that are against the basic principles more or less. Worker's group activity is, essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. In practice, however, many groups are so typical and so impetuous of the material effect that it is worried to be inclined to outform rather than contents. To prevent this point it is recommended that worker's group activity be promoted continuously and on the basis of the original principle of small group activity to obtain practical and rich results, and systematically to be more effective and active considering the managerial environment and the intellectual level of the consisting members.

In this paperm we provide a plan of construction, employment and management of the Korean postal address database and discuss the design of to-be models for it. For the purpose, we adopt and modify the information strategy planning methodology to fit it into our study. We examine the managerial environments and limitations of the postal services and define the requirements as a result. The U.S. Postal Service (USPS) was chosen as the best practice for a benchmarking and gap analysis with its advanced management of address information. After analyzing the current status of the postal business processes and information systems used, we classify the products and the services of USPS by the process to which they are applied and propose a deployment plan. In order to design a to-be model, we define the operating and managing functions for the address database and specify the scenario according to the functions. By managing the address database and supporting the postal services, it could be possible to make the business competitive and satisfy the customer demands.

This paper reports an empirical study on assessment of R&D best practices. The principles of quality management and their tools such as best practices or benchmarking have been so prevailing in the operational process that the R&D management recently consider extensive use of them for their innovation process. However, characteristics of the two processes may be different each other. Are the principles or the tools that were effective in the operational field still going to be effective in the innovative field? In order to answer the question, we statistically examine how R&D best practices contribute to the innovative performance. Upon literature review on technological innovation, we present a R&D process model whereby we set forth research hypotheses. Using data from 66 successful R&D efforts carried out among Korean firms mostly between 1999-2001, regression analyses reveal that best practices used in most stages throughout the R&D process are found not to significantly contribute to the innovative performance. Only those in technology strategy and prototyping stages are proven effective for technical and commercial performance respectively. Interestingly, efforts in a problem solving and improvement stage are counterproductive in the case of the innovation process. Discussions on our empirical observations are presented followed by some managerial implications.
