Pooling works when the needs of the participants are independent or exclusive. Those who remain in demand can fill those who lack. However, this study began by wondering what would happen if participants had opportunism in this pooling process. The hypothesis is that the opportunism of the participants reduces the pooling effect.
Experiment and simulation were combined to test this hypothesis. The experiment confirmed that the subject had opportunism in the pooling situation. And the simulation confirmed the impact on pooling. After the morning sale was completed, the experiment subjects received help for afternoon sale by pooling. When pooling, the order quantity was checked for distortion in order to receive more.
It is expected that phantom orders will increase when receiving an additional supply rather than a return. And the experiment was to see how much occurs. The overall pooling effect was measured by implanting the decision function found in the experiment into the simulation model. Pooling consists of one seller and two buyers. The effect is quantified by simulating the case that one buyer has opportunism and non-opportunism.

Since the 1990s, the European Union has tightened various environmental regulations on companies, environmental factors have become an important issues for decision makers. As a result, corporate purchasing managers began to make efforts to reflect supplier selection and evaluation in consideration of environmental issues. Accordingly, various studies have been conducted on the selection of green suppliers, but studies have been conducted to measure the importance of the selection criteria of industrial companies of purchasers. Therefore, the main purpose of this study is to examine the difference between the importance of the selection criteria and the supply performance, and the difference between the manufacturer's business performance and the supplier's supply performance through a review of the manufacturer's selection criteria for the market environment. Furthermore, it aims to identify the relationship between supplier performance on selection criteria and business performance with manufacturers.
To achieve the purpose of this study, empirical analysis was carried out for 70 purchasing managers of manufacturers in the electrical, electronic and heavy chemical industries. Based on the previous research, we were able to derive a total of six supplier selection factors such as eco-friendliness, quality, relationship, flexibility, price and delivery, and finance. Corresponding sample t test and independent sample t test were performed. Finally, multiple regression analysis was used to analyze the correlation between supplier performance and manufacturer's performance on selection criteria. The results showed that eco-friendliness, flexibility, price and delivery factors had a statistically significant relationship with the manufacturer's performance.

With increasing interest in and the significance of the logistics industry in the Republic of Korea, it is essential for logistics educators to meet the educational requirements in higher education institutions (HEIs), which are of high importance to the industry. However, there is no comprehensive research that organises information on HEIs offering logistics majors. Using higher education data in Korea, this study scrutinises the present situations of 37 Korean HEIs regarding logistics majors. Cluster analysis, used to group university curricula according to similar characteristics, identified five different groups, which demonstrates that the focus of the curricula at such HEIs differs. The findings of this preliminary study will provide basic understanding concerning logistics education in Korea and suggest some direction for further academic research.

This study analyzed 11 capacity units and 38 competency unit elements which have been developed for logistics management tasks in National Competency Standards (NCS) and suggested a logistics education models for operation of training courses for logistics related employees. In addition, the effect on the logistics performance of an enterprise was analyzed by using a structural equation according to the character of the curriculum when the NCS-based education course is operating. The result show that the effect on logistics performance of the company was different by each unit of capacity and the same units of capability have different effects on logistics performance depending on whether NCS-based educational operation are mediating.
In addition, we found that there is the unnecessary structural curriculum in NCS structure and have a synergy effect when it is operated with another curriculum. Therefore, supporting system should be provided to flexible curriculum operations according to the character of the tasks in accordance with the needs of logistics enterprise.

Bonded Goods Caretaker is a qualified person certified by the state who must necessarily be employed by bonded area operator (including bonded warehouse, bonded factory, duty-free shop, etc.) to run a bonded area. Bonded Goods Caretaker is also a professional person in charge of bonded goods who, being possessed of expertise, partially performs the duties of customs officers by commission with regard to the control of bonded goods. Currently, however, without grades given on such qualification and with poor means to enhance professionalism such as supplement education, he is even forced to hold other posts concurrently, which is legally prohibited. Accordingly, this study is aimed to propose an improvement plan on the system of bonded goods caretaker. First, factors related to an improvement plan were drawn by reviewing foregoing studies and survey was conducted by composing these factors with four categories and twenty-two subcategories. Workers at bonded area (operator, person in charge, bonded goods caretaker, customs officers) were surveyed and through response to the questions, rankings for improvement factors were drawn. Next, additional analysis was conducted via one-way ANOVA for each subcategory on whether there was difference in perceiving importance among bonded area workers. It is expected that the results of this study could be used to improve conditions for bonded goods caretakers and enhance their professionalism, independence, etc. through policy proposals related to bonded goods caretaker system.
