It is not easy for business workers to find proper information for his job, because of the following problems:(1) information exist in various information system both internal and external with diverse formats(2) he cannot estimate relevance of all the information and (3) he cannot select proper information among large volume of information. The requirements for the systems are the following things:(1) search of relevant information from various internal and external information systems(2) proving an integrated view of information for workers, and (3) information processing and decision-making are seamlessly integrated fro business workers. We proposed an agent system to fulfill the requirements. We focus on the purchasing job, and developed a prototype system. PIPA(Purchasing Information Process Agent). The PIPA performs not only information processing jobs(information search gathering, display, business form -making)but also decision-making support job (evaluation of supplier candidates, and apply of sourcing policy) for sourcing manager. The framework of the PIPA can be appled to other information processing and desision-making jobs.

The purpose of this study was to identify the relationship of clothing involvement and clothing buying behavior of women. A questionnaire was developed to measure clothing involvement, clothing purchasing motives, clothing purchasing criteria, fashion information sources, store selection criteria, and demographic characteristics. The questionnaire was administered to 430 female adults in Taegu. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were s follows: 1. Subjects were divided into low clothing involved and high clothing involved groups. 2. Three dimensions of clothing purchasing motives were derived by factor analysis such as Aesthetic dependant, Impulsive, and Practical motive. Clothing purchasing criteria were factor analysed as Aesthetic, Qualitative, External, and Economical criterion. Fashion information sources were factor analysed as Printed & audio-visual oriented media, Marketer intensive search, Store search, Observation & Interpersonal search, and Experience. Store selection criteria were factor analyzed as Merchandise & Store atmosphere, Store convenience, and Brand & fashion. 3. There were significant differences between high involved and low involved consumers in clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about purchasing criteria expecially in aesthetic dependant. The high involved consumers put more importance to aesthetic, qualitative, and external criterion as clothing purchasing criteria. The high involved information sources. The high involved consumers were more concerned about merchandise & store atmosphere, and brand & fashion than low involved consumers in store selection criteria.

The purpose of this study is to examine which factors are encouraging SMEs to participate in uTradeHub(focused on the uTrade search service) in terms of product characteristics and sourcing patterns. The three factors encouraging Trade e-Marketplaces are identified in this study. First, internal factors include the support of top management, mature of IT infrastructure. Second, external factors include the pressure of industry, industry competition, dependence of trading partners. Third perception factors are perceived Usefulness, perceived easy of use. The empirical analysis had the following results. First, it reveals that support of top management, mature of IT infrastructure, industry competition have significant influence upon uTrade Search Services. On the other hand, pressure of industry, dependence of trading partners, Perceived relative benefits are not significant variable of the participation in uTrade Search Services. Second, the factors affecting the participation in uTrade Search Services are differentiated in terms of product characteristics and sourcing patterns. And the support of top management, mature of IT infrastructure, Perceived relative benefits are emphasized very important factors affecting the participation of uTrade Search Services in SMEs. The industry competition is recognized as more important factor in horizontal market in which Spot sourcing just like Operating products is trading. On the other hands, the dependence of trading partners are significant factor in vertical market in which Systemic sourcing just like Manufacturing products is trading.

In this paper, we propose a new submesh allocation scheme which improves the performance of multicomputer systems. The key idea of this allocation scheme is to reduce waiting time of task by minimizing the submesh search time and the submesh a]location delay caused by external fragmentation. This scheme reduces the submesh search time by classifying independent free submeshes according to their types (square, horizontal rectangle, vertical rectangle) and searching a best-fit submesh from the classified free submesh list. If a submesh allocation delay occurs due to external fragmentation, the proposed scheme relocates tasks, executing In allocated submeshes, to another free submeshes and compacts processor fragmentation. This results in reducing the submesh allocation delay. Through simulation, we show that it is more effective to reduce the submesh allocation delay due to external fragmentation than reducing the submesh search time with respect to the waiting time of task. We also show that the proposed strategy improves the performance compared to previous strategies.

The goal of this article is to ascertain the factors that govern consumers' choosing to outbound travel product. The authors assess the consumers' travel product choosing processes with information search(internal knowledge, external information knowledge). alternative evaluation(perceived image, emotional experience, price acceptability, appeal, trust), and alternative choice(purchasing intention). Using data on Thailand travel product, the authors find considerable results and conclude by discussing prescriptive recommendations for the travel industry.

This paper has been studied a real-time video frame data processing control that used the linear systolic array for motion estimation. The proposed data control processing provides to the input data into the multiple processor array unit(MPAU) from search area and reference block data. The proposed data control architecture has based on two slice band for input data processing. And it has no required external control logic blocks for input data as like reference block or search area data.

Current paper investigates the dynamic behavior and stability of an infrared search and track subjected to external disturbance having gimbal structure with three rotating axes keeping constant angular velocity in the azimuth direction. Euler-Lagrange equation is applied to derive the coupled nonlinear dynamic equation of motion of infrared search and track and the characteristics of dynamic coupling are investigated. Two equilibrium points with small variations from the nonlinear coupling system are derived and the specific condition from which a coupled equation can be three independent equations is derived. Finally, to examine the stability of system, Lyapunov direct method was used and system stability and stability boundaries are investigated.

Recent studies focus on how open innovation strategies affect innovation in enterprises, but lack research related to the forms of openness. There is also a paradox that an entity should open up for open innovation but also protect its innovation. In this regard, the need for research on innovation protection has expanded. Therefore, this study looked at the effect of the form of openness on product innovation, and explored how the relationship between the form of openness and product innovation depends on the appropriation mechanisms. This study used data from the Korean Innovation Survey(KIS), which was developed and distributed by the OECD. The main findings of this study are summarized as follows. First, the forms of openness has a positive effect on product innovation. Specifically, external search has had a positive impact on exploitative innovation, and collaboration has shown to have a positive impact on exploratory innovation. Second, the appropriation mechanisms has a positive moderating effect on the relationship between the forms of openness and product innovation. Specifically, it was shown that formal appropriation mechanisms had a positive effect on the relationship between external search and product innovation, and that informal appropriation mechanisms had a positive effect on the relationship between collaboration and exploratory innovation. This study is expected to contribute to: First, this study has divided the forms of openness into external search and collaboration, unlike the existing method, and thus identified the type of product innovation and the appropriation mechanisms and forms of openness by identifying the impact on product innovation. Second, depending on the characteristics of the appropriation mechanisms, it was identified that it had the moderating effect on the forms of openness and the relationship of product innovation, so that depending on the type of openness and the type of product innovation, the type of appropriation mechanisms more suitable was identified.

This paper investigates how internal knowledge dependency and its interaction with external knowledge adoption affect innovation performance in Korean companies. We categorize innovation performance into exploratory innovation and exploitative innovation. Especially, we examine business group effects as group headquarters and sister subsidiaries holistically form the boundary of the firm. Our empirical results first suggest that the degree of internal knowledge dependency is positively associated with exploitative innovation, but negatively with exploratory innovation. Second, internal knowledge dependency is more negatively related to exploratory innovation in independent firms than in business group affiliates. Third, independent firms' adoption of external knowledge tends to strengthen the positive relationship between internal knowledge dependency and exploitative innovation. Finally, exploitative external knowledge search appears to strengthen the negative relationship between internal knowledge dependency and exploratory innovation in both types of firms.

In the treatment of Nasal Polyps. which are produced with allergic rhinitis, chronic paranasal sinusitis at clinic. Herb-med., acupuncture and some medicine for external application have been used. The symptoms, however, has taken a turn for the better in temporary, the nasal polyps was not removed in completely. So the origin treatment was impossible by the use of herb-med.. acupuncture and medicine. Although a surgical operation (excision) of western-medicine is effective for a specified period of time (about 6 months), the nasal polyps tend to recur. Because of that the second and third operation might be needed, so we cannot consider the operation as the treatment of nasal polyps. The study was observed to investigate the nasal polyps treatment, and to search practical attempt for the clinic application through a literature study on Bisikyuk and Bithch which are similar with nasal polyps. As results, the practical application of external treatment for the nasal polyps treatment in clinic might be more necessary, and internal use of the Herb-med. with the external treatment might be treated as supplementary treatment.
