고시근,구평회,하재원,권혁무,김동준 한국품질경영학회 2004 품질경영학회지 Vol.32 No.2

The TOC/DBR and Six Sigma are the most attention-getting concepts for managing manufacturing companies in Korea. Using the ideas and methods of the TOC/DBR, companies can achieve a large reduction of work-in--process and finished-good inventories, significant improvement in scheduling performance, and substantial earnings increase. The Six Sigma approach derives the overall process of selecting the right projects based on their potential to improve performance metrics and selecting/training the right people to get the business results. These two concepts have different backgrounds and different viewpoints for production systems. So, if the two concepts collaborate each other, the synergy effects to innovate production systems can be expected. This paper proposes a new approach to implement the TOC/DBR concepts in production systems. This approach uses some concepts of Six Sigma which stresses educations, project approaches (step by step procedure using a Roadmap), and improvement philosophy.

본 연구는 웹 사이트 사용자들의 인지도에 영향을 주는 요인이 무엇인가를 밝히고자하는데 초점을 두고, 웹 사이트 재방문(재사용) 의도에 영향을 주는 정보시스템의 질, 정보의 질, 인지된 사용의 용이성, 인지된 유용성, 웹 사이트 선호, 그러고 컴퓨터 경험 및 성의 조절효과를 검증하고자 했다. 본 연구가설의 검증결과를 요약하면, 다음과 같다. 첫째, 정보시스템의 질과 정보의 질은 인지된 사용의 용이성에 유의하게 陽(+)의 영향을 미치는 것으로 나타났다. 그러나, 이들 사이에 조절변수로 사용된 컴퓨터 경험은 조절 변수의 역할을 하지 못하고, 오히려 독립변수의 역할을 하는 것으로 나타났다. 둘째, 인지된 사용의 용이성이 인지된 유음성에 유의하게 陽(+)의 영향을 미치는 것으로 나타났다. 또한, 인지된 사용의 용이성이 웹 사이트 선호에 유의하게 陽(+)의 영향을 미치는 것으로 나타났으나, 이들 사이에 조절변수로 사용된 성(gender)은 조절변수의 역할을 하지 못했다. 셋째, 웹 사이트 선호가 웹 사이트 재방문 의도에 유의하게 陽(+)의 영향을 미치는 것으로 나타났으나, 이들 사이에 조절변수로 사용된 성(gender)은 조절변수의 역할을 하지못했다. This study addresses why users accept or reject a Web site and how user’s acceptance is affected by the features(i.e. IS quality and information quality) provided by a Web site. In considering such an issue, it is believed that IS quality and information quality are very influential factors in determining the user’s beliefs of usefulness and ease of use of a Web site. The user’s perceptions of a Web site are considered by applying the technology acceptance model(TAM). TAM has been widely used to predict the acceptance of a new technology, such as the acceptance of new S/W packages. It postulates that the two variables, perceived usefulness and perceived ease of use. In this study, perceived usefulness and ease of use of the Web site, preference for the Web site, and willingness to revisit the Web site are used to measure beliefs, attitude and intention, respectively. Since the design of a Web site is within the framework of IS, it is postulated that the beliefs about a Web site(i.e. perceived ease of use) is a function of the IS quality and information quality. The following are the summary of the test results of the research hypotheses. First, IS quality and information quality are posited to exert simultaneous, direct, and linear influences on perceived ease of using a Web site. Perceived ease of use of a Web site can be statistically significantly predicted by two paths from IS quality and information quality. But, computer experience isn’t moderated between the IS quality and information quality and the perceived ease of use. Second, perceived usefulness is statistically significantly predicted by one path from perceived ease of use. Third, preference for a Web site is statistically significantly predicted by on path from perceived usefulness, But, gender isn't moderated between the perceived usefulness and the preference for a Web site. Fourth, intention to revisit a Web site is statistically significantly predicted by one path from preference for a Web site. But, gender isn't moderated between the preference for a Web site and the intention to revisit a Web site. Conclusively, the significant relationships may be attributed to the possible causal effect chains, that is IS quality and information quality → perceived ease of use → perceived usefulness → preference for a Web site → intention to revisit a Web site → (actual use) as similarly shown in Fig. 1.

퇴화성 제품의 최적 가격결정 및 재고정책

고시근,김병남 釜慶大學校 1999 釜慶大學校 論文集 Vol.4 No.1

This study addresses the production quantity problem in which the price and the lot size are considerd simultaneously for items with varying rate of deterioration. The Weibull distrubution is used to represent the distribution of the time to deterioration. The demand of the product is assumed to be a function of the item's price. The effects of two issuing policies. LIFO and FIFO. are investigated on the system profit. Due to the complexity of the objective functions developed, the pattern search method is employed to find the optimal values of the decision variables.

  One engaged in the business of selling or otherwise distributing products who sells or distributes a defective product is subject to liability for harm to persons or property caused by the defect.<BR>  The Purpose of this paper is to clarify the defendants, damages, defenses and time-limitation on products liability claims in China.<BR>  In most products liability cases, the only or principal defendant is the manufacturer that designed, manufactured, and marketed the product which injured the plaintiff.<BR>  Depending on the nature of the claim the plaintiff may recover compensatory damages for personal injury, property damages, and economic loss. Even if the plaintiff proves all of the elements necessary for tort liability, the defendant product seller may be able to avoid or reduce its liability by establishing an affirmative defense.<BR>  The time period of statutes of limitation is 2 years and the time period of statutes of repose is 10 years.

2010년 Incoterms의 특징에 관한 연구

이시환(Shie-Hwan Lee) 한국국제상학회 2010 國際商學 Vol.25 No.4

IncotermsR 2010 were launched in mid-September 2010 and will come into effect on 1 January 2011. The new rules reflect the changes in international trade since the last version of the rules was published in 2000. The most significant change is the addition of two new rules: Delivered at Terminal (DAT) and Delivered at Place (DAP). In turn, the ICC has abolished four Incoterms rules (DAF, DES, DEQ and DDP). The new incoterms are also aimed at being more user friendly, in particular with the use of guidance notes at the start of each rule, providing users with more information and directing them to the correct rule. As has always been the case, Incoterms 2010 will only apply with force or by law if the parties voluntarily contract on the basis of these terms. Given the January 1, 2011 effective date of the new Incoterms, it will be important for traders who wish to keep on using the previous version of the Incoterms to provide a specification to that effect.

N/A In order to evaluate myocardial energy fuels during fasting and exercise, the myocardial glycogen content and the level of plasma free fatty acid were measured. In the 24 and 48 hours fasted rats, the myocardial glycogen content was increased significantly compared with that of the normal rats. But in the skeletal muscle, rectus femoris muscle in lower limb, the glycogen content was decreased by fasting. And the level of plasma free fatty acid was increased up to two to three times of the level of control rats in the 24 and 48 hours fasted rats. The treadmill running, for 30 and 120 minutes, was loaded on the normal group and 24 and 48 hours fasted groups. The myocardial glycogen content was not changed by exercise in the normal rats. But the content of glycogen was increased proportionally to the duration of exercise loaded in 24 hours fasted rats. In 48 hours fasted rats, the glycogen content was decreased by exercise like that of skeletal muscle. The highest content of myocardial glycogen and the level of plasma free fatty acid were found in the 24 hours fasted, 120 minutes exercise loaded rats. It suggest that fatty acid is used in preference to carbohydrate when the carbohydrate and lipid are present together in heart muscle. During utilization of fatty acid in the conditions of fasting and exercise, the glycogen was accumulated in myocardium.
