최근에 응용 개발의 복잡성을 숨겨주고, 상위 응용계층에서 필요로 하는 기능을 추상화하여 제공하는 센서 미들웨어에 대하여 많은 연구진들이 주목하고 있다. 미들웨어를 설계하기 위한 요건들은 다수이지만, 그 중에서도 속성 기반 네이밍의 지원은 매우 중요하게 여겨진다. 하지만 현재 연구된 대부분의 미들웨어는 센서 네트워크의 특성을 제대로 고려하지 않고 설계했을 뿐만 아니라 속성 기반 쿼리에 대한 확장성을 제공하는데 한계가 있었다. 본 연구에서는 가상 대응체(Virtual Counterpart) 개념을 적용하여 속성 기반 네이밍을 싱크 노드의 미들웨어에서 가상의 센서 노드가 지원해주는 구조를 제안한다. 개별 센서 노드에서 속성 기반 쿼리를 처리하는 기존의 데이터 중심 미들웨어와는 달리, 제안된 구조에서는 센서 노드에 대응되는 가상의 센서 노드를 싱크 노드의 미들웨어에서 운용하고, 속성 기반 쿼리를 가상의 센서 노드가 물리적 센서 노드를 대행하여 처리한다. 이러한 접근방안을 취함으로써, 하부 네트워크에 비 종속적인 속성 기반 네이밍이 가능해졌으며, 확장이 용이해졌다.

The purpose of the current study is to investigate the underlying reasons of fashion brand repurchase intention formation based on means-end chain theory and to identify whether the price level moderates the relationships between attribute evaluation and re-purchase intention. Questionnaire data from 291 consumers who had purchase experience of casual wear during the last 6 month period through off-line retail shops were analyzed. The results showed that hedonic shopping value had a positive impact on aesthetic attribute and utilitarian shopping value also had a positive impact on physical attribute of fashion product. While aesthetic attribute had a positive influence on brand repurchase intention, physical attribute had no effect on brand repurchase intention. In addition, there was no moderating effect of price level between the links from shopping value to fashion product attribute evaluation. When casual wear companies have to devise price related strategies, they need to pay attention to diverse promotion factors except for product attributes to realize price-based differentiation.

The purpose of this study was to clarify that the effect of consumer's perception of nail store attributes has on intent to revisit (focus on independent stores) by performing quantitative research. The importance of nail stores is increasing with sales amounts and the number of workers, however, previous research in this area is not complete. The reason that this qualitative research should be done before the quantitative research is due to the scant theoretical background in this matter. As the nail market is steadily increasing, determining the factors to make a successful and influential store leading to revisits is very meaningful both academically and in business. For the quantitative study, consumers from 20 years old to less 60 years old who had purchased nail service at independent nail stores were included in the survey. Quota sampling was adopted in the areas where the independent nail stores were located from May 10th to May 30th, 2019, and 262 questionnaires were collected, and those containing insincere respondences were excluded. The most important nail store attribute was reliability (store name value, relationship with workers and A/S) and then the physical environment, economics, product, and promptness. The result depended on demographic factors- younger and lower-income respondents put a premium on the physical environment, promptness, and economics, on the other hand, older and higher-income respondents placed a priority on reliability. The correlation analysis result is that all store attributes (reliability, physical environment, economics, promptness, product) show a statistical significance. A multiple regression analysis was conducted to determine the effects of nail store attribute importance on revisit intention. Promptness, economics, and the physical environment have a statistically significant effect on the consumer's revisit intention.

Data fusion is an attractive technology because it allows various trade-offs related to performance metrics, e.g., energy, latency, accuracy, fault-tolerance and security in wireless sensor networks (WSNs). Under a complicated environment, each sensor node must be equipped with more than one type of sensor module to monitor multi-targets, so that the complexity for the fusion process is increased due to the existence of various physical attributes. In this paper, we first investigate the process and performance of multi-attribute fusion in data gathering of WSNs, and then propose a self-adaptive threshold method to balance the different change rates of each attributive data. Furthermore, we present a method to measure the energy-conservation efficiency of multi-attribute fusion. Based on our proposed methods, we design a novel energy equilibrium routing method for WSNs, viz., multi-attribute fusion tree (MAFT). Simulation results demonstrate that MAFT achieves very good performance in terms of the network lifetime.

In order to improve the performance of relational databases, one has to reduce the number of disk accesses necessary to transfer data from disk to main memory. The paper proposes to reduce the number of disk I/O accesses by vertically partitioning relation into fragments and allowing attribute replication to fragments if necessary. When zero-one integer programming model is solved by the branch-and-bound method, it requires much computing time to solve a large sized problem. Therefore, heuristic solutions using genetic algorithm(GA) are presented. GA in this paper adapts a few ideas which are different from traditional genetic algorithms, for examples, a rank-based sharing fitness function, elitism and so on. In order to improve performance of GA, a set of optimal parameter levels is determined by the experiment and makes use of it. As relations are vertically partitioned allowing attribute replications and saved in disk, an attribute replicating vertical partition method by GA can attain less access cost than non-attribute-replication one and require less computing time than the branch-and-bound method in large-sized problems. Also, it can acquire a good solution similar to the optimum solution in small-sized problem.

Apparel Quality was one of the most important elements to evaluate the reputations of companies and products which affect the consumer's purchasing behavior. From researches on apparel quality, there was no common concept of quality as well as no common dimensions. The purposes of this study were to identify apparel quality concept and to classify the multi-dimensional concept of apparel quality. The research was carried out in theoretical as well as empirical studies. The theoretical study was conducted to find out apparel quality concept and divide apparel quality concept into four dimensions groups. The empirical study followed the theoretical study to confirm the multi-dimensional concept of apparel quality. The empirical study was investigated that the questionnaire was administered to 634 housewives in Seoul, Kwangju, and Busan during the fall of 1996. The data were analysed by LISREL analysis. This study identified that apparel quality was characteristics of consumer's desires for apparel. The results of the theoretical study verified that apparel quality concept was organized into four different dimensions: physical attribute, physical function, instrumental performance, and expressive performance.
