Vietnam's sea-port industry has experienced a significant development in recent years. Especially in Northern Vietnam, both the demand and supply of handling services for containerized cargoes have increased at a considerable rates. Accompany with such movement, the competition among container terminals in the area becomes fiercer. In this paper, Hierarchical Cluster Analysis is employed to classify all 11 container terminals in Northern Vietnam by collecting data concerning terminal competitiveness. After the classification, each group will be discussed in order to reveal more details about their competitive characteristics. The paper consists of five sections. Section 1 is the general introduction. Section 2 provides a general literature review about competitiveness and factors to evaluate competitiveness. Section 3 explains variables and methodology applied to do the analysis. Section 4 presents the results with linkage to the current condition. Section 5 summarizes the analysis results. It is shown that container terminals in Northern Vietnam should not only pay attention to their service qualities but also have to find out an appropriate mechanism to avoid unhealthy competition. The paper is expected to contribute a background for further researches in container terminals' competition in the region as well as hints for operators in planning and making decisions.

The World Customs Organization (WCO) has designed standards to secure and to facilitate the ever-growing flow of goods in international commerce since 9.11 terrorism in U.S.A. These standards are set forth in the SAFE Framework of Standards, which was adopted by the WCO Council at its 2005 Sessions and the SAFE Framework incorporates the concept of the Authorized Economic Operator (AEO), and the Council directed the WCO to develop more detailed implementing provisions for the AEO concept. It is considered to be reliable in customs-related operations and ensures an equivalent level of protection in customs controls for goods brought into or out of the customs territory, whereas it is difficult for many Korean companies to make a decision of introducing the AEO certification programs because of a lack of cost and benefit information. In this article, We have reviewed the definition and the developing status of an AEO programmes and have studied the benefit and expected effect through documentary research methods. Therefore, it is essential for Korean companies to be certified the AEO programmes from Korea customs service for increasing security in international supply chains through risk management and customs compliance, in addition, the key-driver in the future will be expectations from the business community to work with AEO partners.

Customization and personalization services are considered as a critical success factor to be a successful Internet store or web service provider. As a representative personalization technique, personalized recommendation techniques are studied and commercialized to suggest products or services to a customer of Internet storefronts based on demographics of the customer or based on an analysis of the past purchasing behavior of the customer. The underlining theories of recommendation techniques are statistics, data mining, artificial intelligence, and/or rule-based matching. In the rule-based approach for personalized recommendation, marketing rules for personalization are usually collected from marketing experts and are used to inference with customers data. however, it is difficult to extract marketing rules from marketing experts, and also difficult to validate and to maintain the constructed knowledge base. In this paper, we proposed a marketing rule extraction technique for personalized recommendation on Internet storefronts using market basket analysis technique, a well-known data mining technique. Using marketing basket analysis technique, marketing rules for cross sales are extracted, and are used to provide personalized advertisement selection when a customer visits in an Internet store. An experiment has been performed to evaluate the effectiveness of proposed approach comparing with preference scoring approach and random selection.

This study concludes as follows ; The important demographic factors of the use of mobile internet are age, job, marriage, academic career and personal spending money. Totally viewed in the consumer demographics, the typical type of mobile internet users can be described as the young student. On the other hand, sex and family income variables do not significantly affect the use of mobile internet. And the mobile internet users can be categorized by the life-style into four distinct groups, which are named as the innovation oriented group, the practicality oriented group, the conservation oriented group, the ostentation oriented group.

The study attempts to review TQM models used in the health care sector and the obstacles to the application of TQM in the sector. Even though the TQM models in the manufacturing and service sectors were successfully applied, the applicability of TQM in the health care sector is still in question. The reason is the unique characteristics of the medical sector such as medical and management practices. The most of the TQM models in the health care sector come from manufacturing industries. The importance of the professional groups is, however, more emphasized in the sector than in manufacturing sector. The role of the groups are idiosyncratic to the sector. They generate some obstacles to the application of TQM in the sector. The barriers include cultural obstacles of health care organization. It naturally follows that the TQM in the health care sector requires the change of the organizational culture of the sector. The culture embraces the norms, rules, regulations, compensation system, morale, practices, and common experiences. To change the culture needs long term effort and modification of the rules, regulations, compensation system, and practices. It also requires staffs' training in the problem solving methods. The TQM in the health care sector needs that the interested parties should change. Since doctors group and nurses group are controlled in the bureaucratic and authoritative manner, they should learn the problem solving techniques which require the interaction with other groups. The management also needs to learn management skills and get thorough training on them.

Objectives: The purpose of this study was to analyze the effect of outpatient cost-sharing on health care utilization by the elderly. Methods: The data in this analysis was the health insurance claims data between July 1999 and December 2008 (114 months). The study group was divided into two age groups, namely 60-64 years old and 65-69 years old. This study evaluated the impact of policy change on office visits, the office visits per person, and the percentage of the copayment-paid visits in total visits. Interrupted time series and segmented regression model were used for statistical analysis. Results: The results showed that outpatient cost-sharing decreased office visits, but it also decreased the percentage of copayment-paid visits, implying that the intensity of care increased. There was little difference in the results between the two age groups. But after the introduction of the coinsurance system for those patients under age 65, office visits and the percentage of copayment-paid visits decreased, and the 60-64 years old group had a larger decrease than the 65-69 years old group. Conclusions: This study evaluated the effects of outpatient cost-sharing on health care utilization by the aged. Cost sharing of the elderly had little effect on controlling health care utilization.
