In the telematics system, a reasonable path search time should be guaranteed from a great number of user's queries, even though the optimal path with minimized travel time might be continuously changed by the traffic flows. Thus, the path search method should consider traffic flows of the roads and the search time as well. However, the existing path search methods are not able to cope efficiently with the change of the traffic flows and to search rapidly paths simultaneously. This paper proposes a new path search method for fast computation. It also reflects the traffic flows efficiently. Especially, in order to simplify the computation of variable heuristic values, it employs a simplification method for estimating values of traffic-adaptable heuristics. The experiments are carried out with the $A^*$ algorithm and the proposed method in terms of the execution time, the number of node accesses and the accuracy. The results obtained from the experiments show that the method achieves very fast execution time and the reasonable accuracy as well.

본 연구는 국내 지식기반산업에 종사하는 기업을 대상으로 탐색의 소재(locus)와 특성을 기준으로 기업의 지식탐색 유형을 도출하고, 각 유형별로 혁신성과는 어떤 차이를 보이는지 구성형태적 관점(configurational approach)으로 분석하였다. 기존의 지식탐색 연구들은 주로 지식탐색과 결과변수와의 관계규명에 집중해왔다. 이에 따라, 실제 기업들이 어떻게 지식탐색을 조직화 하는가에 대한 이해가 상대적으로 미흡한 수준이다. 따라서, 본 연구는 기업의 지식탐색을 탐색의 소재와 특성에 따라 외부탐색 범위(external search breadth), 외부탐색 깊이(external search depth), 내부탐색 범위(internal search breadth), 내부탐색 깊이(internal search depth)로 지식탐색의 네 가지 차원으로 구분하고 군집분석(cluster analysis)을 통해 실제 기업의 지식탐색 유형을 도출하였으며, 지식탐색 유형에 따라 기업의 혁신성과가 어떤 차이를 보이는지 분석하였다. 연구의 주요 결과는 다음과 같다. 첫째, 상이한 지식탐색 유형을 가지는 6가지 기업군을 도출하였다. 각 기업군은 모든 지식탐색 차원에 대해 적극적이거나, 일부 차원에만 집중하는 등의 차이를 보인다. 둘째, 각 기업군의 혁신성과는 지식탐색 유형의 특성에 따라 탐험적 혁신과 활용적 혁신성과에서 차이를 보이는 것으로 나타났다. 본 연구는 환원론적 접근(reductionistic approach)에 기반한 기존 연구와는 달리, 구성형태적 접근을 적용하여, 기업의 실제 지식탐색 유형을 규명하였다는 점에서, 주요 공헌이 있으며, 연구 결과를 바탕으로 향후 연구 방향을 제시하였다.

This study investigates the effects of appearance management behaviors on job search efficacy among female college students. Based on previous studies on appearance management behaviors and job search efficacy, the questionnaire items were developed. For the study, we conducted a questionnaire survey among 312 students from women's university in Seoul. The statistical analyses were performed using SPSS 23. The results were as follows. First, three types of appearance management factors have been identified: 'fashion & hair,' 'skin care & plastic surgery,' and 'body shape'; the reliability and validity of these factors were proved. Second, the appearance management behavior of female college students found to have a partially significant effect on job search efficacy: fashion & hair factor had a positive effect on job search strength; fashion & hair factor and body shape factor had a positive effect on job search skills. While skin care & plastic surgery factor had a negative effect on job search strength and job search skill. Third, between academic years, there were differences in job search efficacy but not in appearance management behavior. By majors, there were differences among skin care & plastic surgery factor, body shape factor, and job search strength factor. These results suggest that to improve the job search efficacy, proper appearance management through fashion and hair, and body shape management is necessary. In addition, it suggests that it is important to improve the effectiveness of employment by establishing the appearance management strategy that matches the characteristics of each major.

The purpose of this study is offering appropriate system and training program to helf the system designer and the trainer in addition to analyze information use behavior about the web search tools and evaluate the estimated system by user groups. The results of the study are as follows $\circledS1$ It is desirable to consider age than other demographic variables in the case of web search tool. $\circledS2$ It is desirable to design Directory Search Tool in the case of web search tool which serves the student user group. $\circledS3$ An Intelligent Search Tool is more appropriate for the students who are using keyword search tool than any other tools. $\circledS4$ A discussion about standard classification of the web information should be accomplished soon because users feel confused in using web search tools due t o absence of standard mode of classification about classified item. $\circledS5$ Librarians need the cognition about data on internet s a source of information and need positive service and user training program about these information because student users hardly get help from librarians or library orientation for learning method to use web search tool. $\circledS6$ Internet use experience and years of computer use had effect on their use ability when using web search tool, whereas computer use experience, library use experience and Online Public Access Catalogs (OPAC) use experience had no effect on it. Especially, OPAC use experience had no effect on use ability of web search tool of student user group because student user groups had no information about internet and web search tool and they did not recognized the difference about search method between web search tool and OPAC. $\circledS7$In the case of web search tool, it si important to index the increasing web resource automatically by a searching robot. But in the case of student users, web search tool is much more needed to index by index expert due to the absence of ability about selecting and combining keyword.

This study was intended to find the use patterns of internet search engines of librarians and to measure the relationship between internet use frequency and the use behavior of internet search engines. The results showed that librarians use Web search engines for academic information retrieval and are satisfied with the search results. The major problems when librarians use search engines were that search engines retrieve many non-relevant documents. As a result of hypotheses test, the relationship between internet frequency and the preference of search engines was not significantly different. On the other hand, the hypotheses that internet frequency affects satisfaction of search results, recognition of importance of search engines, and the need of retraining of librarians for internet information retrieval were shown to be significant.

Geospatial information, which is one of social overhead capital, is predicted as a core growing industry for the future. The production of geospatial information requires a huge budget, so it is very important objective of the policy for geospatial information to prevent the duplication of geospatial projects. In this paper, we proposed a semantic search system which extracts possible duplication of geospatial projects by using ontology for geospatial project administration. In order to achieve our goal, we suggested how to construct and utilize geospatial project ontology, and designed the architecture and process of the semantic search. Moreover, we showed how the suggested semantic search works with a duplicated projects search scenario. The suggested system enables a nonprofessional can easily search for duplicated projects, therefore we expect that our research contributes to effective and efficient duplication review process for geospatial projects.

검색전략(檢索戰略)은 효과적인 탐색을 수행하는 수단이다. 검색전략(檢索戰略)의 여러 연구 중에서 베이츠의 탐색전술은 자주 인용되고 소개되어 왔으나, 대부분의 연구는 피상적이었다. 본 논문에서는 베이츠의 탐색전술의 내용을 자세하게 조사하고 베이츠의 탐색전술에 기초하여 실제 온라인 탐색과정을 기술하려고 노력하였다. 사용된 전술(戰術)을 구분하기 위하여 다음의 3가지 유형의 조사가 이루어 졌다. (1) 다른 유형의 조직에 속하고, 다른 유형의 데이터베이스를 사용하는 7명의 탐색자와의 면담 (2) 온라인 탐색 레코드의 분석 (3) 1년간 신문 데이터베이스의 검색 신청서의 분석 결론적으로 베이츠 전술의 일부가 빠지고 자주 사용된 새로운 전술이 추가되었다. 다음의 5가지 요소가 온라인 검색행위(檢索行爲), 검색전략(檢索戰略), 검색전술(檢索戰術)에 영향을 미친다. (1) 탐색요구의 난이도 (2) 데이터베이스의 내용 (3) 온라인 탐색의 요금정책(검색비용의 부담자) (4) 탐색과정에서 이용자의 동석여부 (5) 탐색자의 온라인 경험 제한된 조건에서 전형적인 전술이 제안되었다. 그러나 전술의 사용유형을 일반화하기 위해서는 많은 조사연구가 필요하다.

Many prior studies have been conducted that positive reviews increase the intention to purchase. However, there are very few papers that have studied the impact of review search on purchase satisfaction. It is meaningful to study the impact of review search on purchase satisfaction as it can lead the business successfully by inducing repurchase. There is also no study of how review search have different effects on purchase satisfaction among countries. Given the growing number of cross-border e-commerce, we believe that the need for research is high because identifying these differences between countries can have a very important impact on a company's successful overseas expansion. Therefore, in this study, the impact of positive and negative review search on purchase satisfaction and the national impact were set up as a research model. In order to verify this research model, the survey was distributed to those who experienced online purchase in Korea and China, and a total of 234 copies were collected, including 125 copies in Korea, 109 copies in China, and the research model was verified using Smart-PLS structural equation analysis tools. First, positive review search has been shown to positively affect purchase satisfaction. Second, it has been shown that negative review search also has a positive effect on purchase satisfaction. Third, the impact of positive and negative review search on purchase satisfaction was different between Korea and China. While Korea is more aggressive in review search than China due to its high tendency to avoid uncertainty, China is less likely to avoid uncertainty than Korea and is more likely to rely on brand familiarity. Therefore, according to the uncertainty avoidance moderation effect the impact of positive and negative review search on purchase satisfaction was higher in Korea than in China. In this study, Shopping mall managers need to take strategic measures to maximize shopping mall performance by recognizing positive aspects of negative review search on purchase satisfaction. Companies and managers in Korea and China can establish strategies to promote product sales when companies enter the global market.
