In-vehicle multimedia systems are one of the most important factors in the automotive industry. Especially, multimedia systems are more important in advanced commercial vehicles such as premium express buses. In this paper, we proposed a multimedia streaming system architecture using MEP(MOST Ethernet Packets) for premium express buses based on MOST150. We have designed and implemented the prototype of proposed multimedia streaming system. We have designed a board based on i.MX6 to operate a proposed multimedia streaming system. The software has designed a multimedia system for premium express buses based on Android which is an open source platform. MOST(Media Oriented Systems Transport) is a high-speed multimedia network technology for in-vehicle multimedia system. The MOST network is able to manage up to 64 devices and ring topology is used basically. In addition, the MOST Network meets EMI(Electro-Magnetic Interference)/ EMC(Electro-Magnetic Compatibility) requirements because it uses plastic optical fibers(POF).

The purpose of this study was to evaluate the bond strength of rebase resin to denture base resin. The denture base resins in this study were Premium Super-20(Lang Dental Mfg. Co. Inc., Wheeling, USA) and Lucitone 199(Dentsply International Inc., York, USA). And the rebase resins were Repair Acrylic(Lang Dental Mfg. Co. Inc., Wheeling USA). Toughron Rebase(Miki Chemical Product Co. Ltd., Japan) , Tokuso Rebase(Tokuyama Soda. Co. Ltd., Japan) and Triad VLC Reline Material(Dentsply International Inc., York, USA). The obtained results were as follows : 1. The bond strength of Repair Acrylic to Premium Super-20, and that of Toughron Rebase to Lucitone 199 were the highest. 2. In Premium Super-20 and Lucitone 199, bond strength of all rebase resins had significant differences. 3. The bond strength of Triad VLC Reline Material was inclined to the lowset.

"Does CRM benefit affect repurchase or WOM? What is difference between VIP customers and non-VIP customers on CRM benefit?" is the interesting issue on premium industry such as a hotel business. This study examines how social benefit, psychological benefits, economic benefits and customization benefits affect repurchase and positive WOM in premium hotel. Only three of the four benefits showed significant results in repurchase and positive WOM. Also interactions between customer type and benefits were different in repurchase and WOM. The results figure out that VIP customers depend on psychological benefits and customization benefits on repurchase, whereas VIP customers depend on only social benefit on WOM. This finding suggests that hotels need to develop VIP program and approach differently to increase the repurchase volume or positive WOM effect.

Bonus-Malus system in automobile insurance rewards claim-free policyholders by premium discounts and penalizes policyholders with claims by premium surcharges. The purpose of adopting bonus-malus system is to alleviate differences in risk propensity. A well-known side-effect of bonus-malus system is the tendency of policyholders to pay small claims themselves and not report them to their, in order to avoid future premium increases. This phenomenon is called hunger for bonus. In this paper, we introduces an alternative approach to the Bonus-Malus system in automobile insurance - the approach is based on a deductible theory; and then search for a proper way combining both of them. Also, we construct a new algorithm to determine the optimal strategy of the policyholder based on the proposed model.

It has been pointed out that the classical credibility model used in Korea since the beginning of 1990's lacks in objectiveness. Recently, in order to improve objectiveness, the empirical Bayes credibility model utilizing general exposure units like the number of claims and premium has been employed, but that model itself is not quite applicable in the country like Korea whose annual and classified empirical data are not well accumulated and even varied severely. In this article, we propose a new and better model, Based on the new model, we estimate both credibility and loss ratio of each class for fire insurance plans by Korean insurance companies. As a conclusion, we empirically make sure analysis that the number of claims is a more reasonable exposure unit than premium.

This study compares brand equity of the fast food industry between Korea and the Philippines. This comparison is conducted by measuring a price premium that the college students in both countries would pay for hamburgers. Three popular fast food chains in each country, Lotteria, McDonalds', and Burger King in Korea and Jollibee, McDonalds', and Burger King in the Philippines, were chosen for the study. Utilizing a brand-based comparative approach, the findings of the study indicated that Burger King showed the highest brand equity for the premium brand image in both countries, whereas both local brands had a lower brand equity compared to international brands. The results of the study provide useful information for international and local brand managers that wish to establish strategies for a brand image, as well as to manage brand equity effectively.

This research investigates the supply chain contract between a distributor and a supplier in which the selling period is relatively short in comparison with long production lead time. At the first stage, supplier who is a Stackelberg leader offers the distributor a contract with a set of parameters, and subjected to those parameters, the distributor places the number of initial orders as well as options. In order to purchase the option, the distributor pays non-linear option premium price with respect to the number of purchased options. At the second stage, based on realized demand, the distributor has the right to exercise option as either put or call which is limited up to the number of purchased options. The wholesale price contract is used as a benchmarking contract. This research has confirmed that the supply chain contract with a non-linear option premium price can help to coordinate the supply chain.

Premium Seles Tool은 상품의 기능이나 특징, 가격, 디자인 등을 이미지나 동영상을 이용하여 알기 쉽게 설명하는 시스템으로 제품 카탈로그와 같은 성격을 지닌다. 그러나 종이 카탈로그와 전자카탈로그는 공간적 제약과 업데이트의 한계로 사용에 불편함이 따른다. 본 논문에서 설계한 MobileCRM PST는 사진이나 동영상을 애니메이션과 유저 인터액션을 통해 제품의 품질을 높일 수 있으며, 모바일의 특성인 이동성이 확보된다. 또한 새로운 컨텐츠 업데이트 시 서버와 모바일에서 컨텐츠를 관리함으로써 사용자는 최신 컨텐츠를 간편하게 받아 볼 수 있다.

Generalized linear models and generalized linear mixed models (GLMMs) are fundamental tools for predictive analyses. In insurance, GLMMs are particularly important, because they provide not only a tool for prediction but also a theoretical justification for setting premiums. Although thousands of resources are available for introducing GLMMs as a classical and fundamental tool in statistical analysis, few resources seem to be available for the insurance industry. This study targets insurance professionals already familiar with basic actuarial mathematics and explains GLMMs and their linkage with classical actuarial pricing tools, such as the Buhlmann premium method. Focus of the study is mainly on the modeling aspect of GLMMs and their application to pricing, while avoiding technical issues related to statistical estimation, which can be automatically handled by most statistical software.
