Studies of epidemiological and prognostic factors are very important for oncology practice. There is a rapidly increasing amount of research and resultant knowledge in the scientific literature. This means that health professionals have major challenges in accessing relevant information and they increasingly require best available evidence to make their clinical decisions. Meta-analyses of prognostic and other epidemiological factors are very practical statistical approaches to define clinically important parameters. However, they also feature many obstacles in terms of data collection, standardization of results from multiple centers, bias, and commentary for intepretation. In this paper, the obstacles of meta-analysis are briefly reviewed, and potential problems with this statistical method are discussed.

A major challenge to supply chain managers is how to control inventories and costs along the supply chain while maximizing customer service Performance. In the literature, although the optimal management of inventory along the supply chain has received considerable attention during the past decades, the attention has been mainly given to multi-echelon control policies. A prerequisite for applying these policies is full information transparency in the supply chain, which is hard to accomplish in practice because it may require major organizational chanties. In the case that a decentralized control (local (R, S) policy) should be used at each location in multi-stave distribution systems, this paper presents the coordinating approach of determining the best policy which satisfies predetermined target customer service levels and minimizes the mean physical stock along the system.

Along with the recent changes in animal feed supply circumstances, many enzyme and probiotic feed supplements have been introduced and applied to pigs and chicken diets. Therefore, both selection of the appropriate feed supplements and their proper supplementation becomes critical to justify the supplementation. Meta-analysis was proposed as an appropriate tool to assess the large amount of relevant information. In this review, reliable data from recent publications was compounded then analyzed to determine the best practice of effective enzyme supplementation from the perspectives of animal species, age, characteristics of feed, target substrates, optimum multi enzymes combination and intended objectives. The results of the analysis suggested pratical methods of probiotic supplementation regarding intestinal microbiota, physiological limitation of probiotics, maximization of the probiotic benefit and synergism with prebiotic supplements.

The purpose of this study is to examine the effects of human resource development policies and practices on social capital and organizational performance. To serve the purpose, we focused on the effects of communities of practice (CoP) to social capital and suggested best practices of CoP from the aspect of social capital. Specifically, we considered new kinds of social capital such as social innovation capital and social integration capital as well as traditional social capital classified into structural, relational, and cognitive capital, Where, social innovation and social integration capital represent corporate's social capacity to innovate and corporate social responsibility (CSR). And then we conducted a multiple case study on Yuhan-Kimberly, POSCO, and HIRA. From the result, we identified that CoP activities have a positive effect on social capital and organizational performance.

This study investigated in vitro antioxidant activity of Sonchus oleraceus L. by extraction solvent, which were examined by reducing power, hydroxyl radical-scavenging activity(HRSA) and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assays. 70% MeOH extract had the greatest reducing power while EtOH extract had the greatest HRSA. The antioxidant activity of S. oleraceus extracts was concentration dependent and its $IC_{50}$ values ranged from 47.1 to $210.5\;{\mu}g/ml$ and $IC_{50}$ of 70% MeOH, boiling water and 70% EtOH extracts were 47.1, 52.7 and $56.5\;{\mu}g/ml$, respectively. 70% MeOH extract of S. oleraceus contained the greatest amount of both phenolic and flavonoid contents. The extracts tested had greater nitrite scavenging effects at lower pH conditions. The cytotoxic activity showed that EtOH extract had the best activity against the growth of stomach cancer cell. These results suggest that S. oleraceus extract could be used as a potential source of natural antioxidants.

The properties of a machine tool greatly affect machining quality since a machine tool has large variance in its features. Machine tool makers want to find best machining condition with the one that they have built. Machine builders need to develop test specimen since it helps finding characteristics of machine tools when the machining properties of the specimen are analyzed. This paper develops test specimen to identify features of the main spindle, the feeding device, and the frame of a machine tool. The specimen is machined with a high speed machine and the features of the machine are analyzed with test items. They are surface roughness, overshoot in axial movement, errors in circular movement, feeding with small movement, and compensational error. This work can improve usability for a machine tool in machining practice.

Conflict is aroused when different people having different interest work together for fulfilling same the objectives. As the construction field is large, complex, volatile and requires tremendous capital, there are always greater challenges and possibility of risks of conflicts. Poor management practices in construction site and trying to protect risks and threats by contracting parties are the cited sources of the construction conflicts. The best management practice is to resolve the problems before these cultivate as conflicts. This paper has identified six dispute avoidance factors-Convince, Coordination, Consideration, Compromise, Consolation and Coercion. Six 'C' factors described in this paper are the mantra (formula) to execute a conflict free construction project. The conflict avoidance factors have been verified through a successfully executed project called TEVT development project (Technical Education and Vocational Training) during 1993-1998 in Nepal. The results show that the six 'C' factors 'C' considered during the implementation of the project, construction conflicts would be controlled or minimized effectively.

To deal with the water pollution arising from the construction site, this study raises the issues of management and laws and it suggest the efficient way to reduce water pollution by through the case studies. In order to study, seven cases were selected from "Construction Environmental Management Best Practice Competition" co - sponsored by Construction Association of Korea and Construction Environment Association. As a study result, there are problems that depending on the characteristic of the construction site environment simple alone settling facilities can not handle muddy and dirty water generated by the construction site. However, when the construction site applied improved water pollution control facilities with reflecting the characteristic of muddy and dirty water. The problem can be solved moreover it can achieve exceeded emission standard. Therefore new regulations and management with water pollution control facilities considering characteristic of environment is needed to cope with water pollution arising from the construction site.

소프트웨어의 재사용은 소프트웨어 개발의 품질과 생산성을 높이고 개발 비용을 절감할 수 있다. 소프트웨어 재사용을 위해서 가장 중요한 것은 소스 코드에서 재사용성이 높은 모듈을 추출하기 위해 모듈화에 적합한 소스 코드를 식별해야 한다. 이를 위해서 우리는 코드 가시화를 적용한다. 정량적 지표인 응집도 지표와 추출하여 코드의 복잡도와 재사용성을 판단한다. 본 논문에서는 객체 지향 패러다임에서 응집도를 재정의 하여 제안하고 모듈 단위를 메소드로 정의하여 모듈의 응집도를 추출한다. 이를 통해 모듈화가 가능한 코드의 재사용과 복잡한 코드의 리팩토링이 가능하도록 한다.

It is the aim of this study to identify and develop improved management practice and competitive edge through co-branding which has been adopted extensively in the States. There is no universally accepted definition of co-branding. The term has been used interchangeably with labels such as brand alliance and composite branding. This study is exploratory in nature and at best a pilot study as few academic research are found dealing with actual cases between hotels and restaurant companies in Korea. Through related literatures reviews and research findings, this study will provide valuable insight as to the methods and activities of co-branding and a framework to help industry professions identify co-branding opportunities to enhance the productivity.
