Mixed-criticality systems consist of components with different criticality. Recently, components are categorized depending on criticality by ISO 26262 standard and DO-178B standard in automotive and avionic domain. Existing mixed-criticality system research achieved efficient and safe scheduling through system-level criticality mode. The drawback of these approaches is performance degradation of low-criticality tasks on high-criticality mode. Task-level criticality mode is one method to address the problem and improve the performance of low-critical tasks. In this paper, we propose probabilistic performance metric for the approach. In simulation results with probabilistic performance metric, we showed that our approach has better performance than the existing approaches.

With the introduction of proptech, this study aims to find out the changes and necessity of introducing blockchain technology, one of the most popular technologies, in real estate electronic transactions. In addition, it is intended to develop evaluation indicators that classify newly created values within real estate electronic transactions and calculate the relative importance of each value area through technology application. To this end, the value that can be created when applying blockchain technology to real estate electronic transactions was classified according to the hierarchy, and considering that the evaluation criteria are complex and the importance can be measured differently depending on various factors, an analysis was conducted according to the AHP method for experts in practical and academic fields. As a result of the analysis, general value showed the highest importance in the first dimension, and digitalization of real estate information showed the highest importance in the second dimension.

The aims of this paper is to examine the key factor of customer satisfaction in the medical service. Especially service waiting is a significant component of the customer's overall satisfaction with the service process. For this purpose, this study proposed 6 hypotheses as follow : H1 : Waiting cost, affect on perceived service waiting, will be different between patient customer group and health care group. H2 : Controllability of the cause, affect on perceived service waiting, will be different between patient customer group and health care group. H3 : Controllability of the cause affect on perceived service waiting, will be different between patient customer group and health care group. H4 : Waiting environment, affect on perceived service waiting, will be different between patient customer group and health care group. H5 : Transaction importance, affect on perceived service waiting, will be different between patient customer group and health care group. H1 : Waiting cost, Controllability of the cause, Controllability of the cause, Waiting environment, Transaction importance, customer satisfaction will affect on service waiting significantly This study find that 1) Waiting cost and Transaction importance are significant variables to influence customer satisfaction between patient group and health care group. 2) customer satisfaction is very important variables to minimize perceived service waiting.

This study aims to analyze the importances of various SCM adoption factors suggested in precedent researches with AHP. SCM adoption factors were categorized by four types: organization factor, transaction factor, relation factor, and information factor. Each factor has sub-factors. Organization factor has five sub-factors: adoption strategy, support of CEO, maturity of information technology, development of assessment system, and innovation leadership. Transaction factor has three sub-factors: transaction period, delivery/quality, and shared goal. Relation factor has five sub-factors: trust, collaboration, inter-dependence, conflict, and immersion. Information factor has three sub-factors: information quality, information share, and information exchange. There are sixteen sub-factors altogether. Analyzing the importances of SCM adoption factors with AHP, the importance of organization factor(.387) ranked the highest. Relation factor(.291), information factor(.167), and transaction factor(.155) followed. Putting the analysis results of primary hierarchy factors and secondary hierarchy factors together, support of CEO(.169) ranked the highest and trust(.124), adoption strateg (.089), share goal(.081), information exchange(.069), collaboration(.064), and information share (.057) followed.

This study compares own-brand exporting SMEs' utilization of various government-run exporting service programs that provided support in searching for overseas distributors, in overseas market research, and in marketing support. Researchers measure how important firms found each of these components of the program, as well as firms' satisfaction with these services, based on the type of product exported (industrial vs. consumer goods) and the level of economic development of the host countries (developed, newly industrialized, and developing.) A total of 245 own-brand exporting SMEs were surveyed and analyzed in this study. Results indicated that KOTRA was the most frequently used organization by the sample SMEs, regardless of the product type and the economic level of host countries. Industrial-goods exporting SMEs found support in searching for overseas distributors more important than consumer-goods exporting SMEs. SMEs exporting to developed countries considered overseas market research and marketing support and searching for overseas distributor programs more important than SMEs exporting to NIE or developing countries. In addition, industrial-goods exporting SMEs were more satisfied with the overseas market research and marketing support and searching for overseas distributor programs than consumer-goods exporting SMEs. However, there were no differences in satisfaction among firms based on the level of economic development of host countries. Several cases of significant correlations between the importance of and satisfaction with the utilization of government exporting service programs were found.

Dongdaemun fashion market has been successfully positioned as a main hub for non-brand fashion product distribution in Korea. One of important competitive advantages of Dongdaemun market often quoted by retail researchers is an efficiently managed network system among supply chain members. This study aimed to examine the importance of buyer-supplier relationship elements and supplier properties from buyers' perspectives (small & very small-sized fashion stores in Dongdaemun market), and to identify the determinants of the relationship length between suppliers and buyers. Survey responses of 233 stores were analyzed using EQS 6.1 for Window and SPSSWIN 10.0. The findings could be summarized as follows: First, fashion stores perceived that right delivery as the most important factor, and geographically closeness, design capability, quality, and lower price followed in order. Second, the characteristics of stores such as location, wholesaling versus retailing focusing, monthly sales, and total business length all affected the perceived importance of buyer-supplier relationship. Third, design capacity, communication, power was identified as determinants of actual relationship length with a supplier, while communication and trust were found to be determinants of future expected relationship length.

온라인거래가 폭발적으로 증가하면서 온라인결제에 대한 이용자 수요가 증가하고 있다. 특히 최근 들어 온라인소액결제는 다양한 디지털재화(MP3, VOD, 사이버머니 등)를 구입하는 데 활발하게 사용되고 있으며, eBay의 PayPal, 구글의 Checkout 등 해외에선 이미 차세대 온라인 비즈니스 영역으로 주목 받고 있다. 온라인소액결제는 전자 상거래에서 사용되는 결제 방식으로 금액이 작은 온라인 거래에서 사용되는 결제를 말한다. 하지만 온라인소액결제에 대한 국내외적인 성장에도 불구하고 이 분야에 대한 연구는 거의 전무한 상황이다. 본 논문에서는 온라인소비자들이 온라인 환경에서 소액결제를 이용할 때, 선호하는 결제수단과 중요시 여기는 속성에 대한 실증연구를 진행했다. 온라인 소액결제는 연령층에 따라 신용카드 결제와 상품권, 사이버머니 등의 결제 선호로 나뉘어 지고, 개인정보 보장 등과 같은 안전성에 관련된 속성을 중요시 하는 것으로 나타났다. 이와 같은 결과는 향후, 온라인 소액결제에 대한 소비자 특성과 도입 및 발전전략에 대한 다양한 해석을 통해 이비즈니스 분야에 실질적으로 활용될 수 있을 것이다.
