<P>There have been controversial results regarding the association between brain-derived neurotrophic factor (BDNF) Val66Met polymorphism and anxiety-related traits such as harm avoidance (HA). We aimed to investigate the interaction between <I>BDNF</I> Val66Met polymorphism and negative life stressors in HA. <I>BDNF</I> Val66Met polymorphism was genotyped in 391 community-dwelling Koreans (152 males, 239 females; 43.2 ± 14.1 years old). The Temperament and Character Inventory (TCI) and the Center for Epidemiological Studies for Depression Scale (CES-D) were self applied. The Structured Clinical Interview for DSM-IV axis I disorders and face-to-face interviews investigating negative life stressors within the last 6 months were also performed. There was no significant difference in TCI score, major depressive disorder prevalence and CES-D score among the 3 genotypes (94 Met/Met, 188 Val/Met and 109 Val/Val subjects). There was no significant difference in TCI scores between subjects with stressors and those without stressors, while more common major depressive episodes (p = 0.03) and higher CES-D scores (p < 0.001) were found in subjects with stressors. However, there was a significant interaction between the <I>BDNF</I> genotype and negative life stressors in HA (p = 0.02). Only subjects with the Val/Val genotype showed higher HA with recent negative stressors. Our finding suggests that <I>BDNF</I> Val66Met polymorphism might influence HA by interacting with recent negative stress experience.</P><P>Copyright © 2009 S. Karger AG, Basel</P>

물류비를 계산하는 방법에는 건교부 지침 등 다양한 기준이 있다. 그러나 물류비를 계산하고 이를 활용하는 데는 어려운 점이 있다. 따라서, 기업이 쉽게 물류비를 계산하고 활용할 수 있는 물류비 관리방법이 필요하다. 현재 제조기업들은 물류비의 규모를 파악하는 수준에 있다. 이를 파악하여 관리함으로써 기업 경영에 중요한 영향을 미치는 물류비를 절감할 필요가 있다. 본 논문에서는 제조기법들의 물류비 계산 및 관리사례와 물류비 절감 대책을 살펴보고, 물류비원가 구성요소인 재료비, 경비, 노무비 측면에서 물류비를 절감할 수 있는 방안을 모색하고자 하였다. Managing of logistics cost is not accounting it, but reducing cost. It can help to control our company's logistics costs. An accounting method that enables a business to understand more clearly how and where it makes a profit. The ability of the firm's logistics cost accounting system gives a truer picture of the cost and subsequent profit associated with serving a given account or chain of distribution. We have three kind of methodology of accounting it. But it is difficult to apply to manufacturing enterprise. On investigation, Lots of company want to know the scale of it and they don't manage it. And so, we need to have access to easy methods of accounting and managing the logistics cost. We studied the methodology of logistics cost reduction in Japan and the cases of accounting it in Korea. The study has been carried out based on the factor of cost structure: material costs, general expenses, labor costs In this paper we try to make suggestions for management method and reduction logistics cost of manufacturing company.

The present paper reports the effects of Hwaotang an atherosclerosis using a spontaneous experimental model, We have also investigated the pharmacological effect of Hwaotang on collagen- and ADP-induced blood platelet aggregation, thrombin-induced conversion of fibrinogen and fibrinolysis in in vitro experiments, and various effects on stimuli-induced superoxide generation in human neutrophils. Hwao-tang was shown to have inhibitory effect on collagen- and ADP-induced blood platelet aggregation, on thrombin-induced conversion of fibrinogen to fibrin and on the activity of plasminogen or plasmin. Hwao-tang also significantly inhibited fMLP-induced superoxide generation in a concentration-dependent manner, but not that induced by arachidonic acid. Hwao-tang inhibited neutrophil functions, including degranulation, superoxide generation, and leukotriene B4 production, without any effect on 5-lipoxygenase activity. In conclusion, the protection of extracts of Hwao-tang on the ischemic infarction induced artificially might be involved to their inhibition of thrombotic action. The results also indicate that Hwao-tang exerts the effects on superoxide generation related to the inhibition of neutrophil functions.

Quality of life due to climate change are different and are seeking a way, that affects most of the water seems to be the field. Carbon dioxide is a greenhouse gas causing climate change in the proportion known to be the most. According to the OECD's 2050 Environmental Outlook in Korea is the OECD country with the most severe water stress was released. Water shortages in 2020, Korea has been known to enter the country. The OECD Green Growth policy of the keyword in the water to be present Water Footprint is produced from raw materials procurement, disposal and recycling of the product's life cycle to calculate the water usage of water resources is a technique to quantify the load. Water footprint calculations are used in the per-unit water consumption. In this study, to measure the carbon dioxide emissions and water usage more accurately measure who try and look for ways to manage

For a sustainable development, the resources circulation system should be established and required alternative logistics area of enterprises. In this paper, we are to suggest a direction through analysis effects, and reduce, recycle, reuse factor of transportation, material handling, packing, information, management in logistics function, and effects of logistics organization on Firm Performance.<BR> We found significant correlations between the constructs extracted above, and between the constructs and firm’s performance. This study was conducted with the subjects of manufacturing enterprises with concurrent reviews of literature and statistical analysis, and the meaning of this study would be the analysis of the influencers of the resources circulation system.

The purpose of this study is to examine the actual condition of environment conscious logistic system which is essential to make material recycling economic society. Environment conscious logistic management which meant simply recycle is tend to promote material reduction, reuse and recycling. We have made case studies about advanced environment friendly logistic system. To examine Korean companies' environment conscious logistic system, we made survey form which is consist of 82 questionnaires and 154 companies have participated for this. And we have analyzed the survey responses. As a result of this study, we propose the way of constructing environment conscious logistic system in Korea.

지속가능발전을 위하여 자원순환형 경제사회시스템이 환경 친화적으로 구축이 요구되고 있다. 이를 위하여 기업에서는 투입자원을 최소화하고 가능한한 자원을 재사용, 재활용하기 위한 리버스 물류의 중요성이 증가하고 있다. 본 연구의 목적은 리버스 물류에 있어서 기업의 환경문제 대응형태가 물류정보시스템 활용과 리버스물류 성과에 미치는 효과, 물류정보시스템 활용수준과 리버스물류성과의 상호관계와 그 영향요인을 분석하여 방향을 제시하고자 하는데 있다. 이 목적을 달성하기 위하여 문헌연구와 실증연구를 병행하였다. 본 연구는 기존의 물류연구들과 달리 리버스 물류에서 환경문제 대응형태에 따른 영향을 분석하였다는데 의의가 있다고 하겠다. The resource recycling system of economy and society is demanded in the environmental conscious way for sustainable development, and the importance of reverse logistics has been increased for corporations to minimize resources invested, and reuse or recycle them as much as they can. In this paper, we are to present a direction to progress, analyzing the effects and the mutual relationship between the responding type of a company to environmental problems, utilization of the logistics information system and reverse logistics performance. To do this, reviews of literature and statistical analysis were carried out side by side. The significance of this study is to analyze responding types to environmental problems in reverse logistics, levels of utilizing logistics information system, and effects on reverse logistics, unlike existing studies on logistics.
