This study focused on appreciative inquiry(AI) of salespeople who have to respond to various types of emotions according to the desires of individual customers at service contact points and the effect of emotional labor on adaptive selling behavior and customer satisfaction. Dyadic questionnaires were administerd to 115 automobile salespeople and 2 customers who received service from each salesperson, and the collected data was analyzed by using structural equation modeling. The results showed that AI had positive influences on deep acting and surface acting. Only deep acting was found to have positive relationship with adaptive selling behavior, but not to surface acting. Adaptive selling behavior had a positive effect on customer satisfaction. This study will contribute to identifying the need for AI access for salespersons and for activating adaptive selling behavior through emotional labor related to AI practice.

This study was performed with a view to examine the nature and difference of EFA(Exploratory Factor Analysis) and CFA(Confirmatory Factor Analysis), and to compare the analysis process and result of EFA and CFA with the same data. The result of empirical analysis was as follows. Meanwhile, p.1, p.3 was removed owing to hampering the convergent validity in EFA, p.3 was removed owing to hampering the discriminent validity in CFA. EFA was reduction process of muti measurement variables to a few factor, but CFA was understanding and confirmatory process of measurement and latent variables' relation. Eventually, this study showed that EFA and CFA used different methology, thus the different outcomes appeared although using the same data, and implicated resonable application of methology according to given data.

The most optimal route-search algorithm thus far has introduced a method of applying node labels and link labels. Node labels consider two nodes simultaneously in the optimal route-search process, while link labels consider two links simultaneously. This study proposes a turn-label-based optimal route-search technique that considers two turns simultaneously in the process. Turn-label-based optimal route search guarantees the optimal solution of dynamic programming based on Bellman's principle as it considers a two-turn search process. Turn-label-based optimal route search can accommodate the advantages of applying link labels because the concept of approaching the limit of link labels is applied equally. Therefore, it is possible to reflect rational cyclic traffic where nodes allow multiple visits without expanding the network, while links do not allow visits. In particular, it reflects the additional cost structure that appears in two consecutive turns, making it possible to express the structure of the travel-cost function more flexibly. A case study was conducted on the metropolitan urban railway network consisting of transportation card terminal readers, aiming to examine the scalability of the research by introducing parameters that reflect psychological resistance in travel with continuous pedestrian transfers into turn label optimal path search. Simulation results showed that it is possible to avoid conservative transfers even if the travel time and distance increase as the psychological resistance value for continuous turns increases, confirming the need to reflect the cost structure of turn labels. Nevertheless, further research is needed to secure diversity in the travel-cost functions of road and public-transportation networks.

This study presents an empirical analysis of job search behaviors by using the 3rd Korean Labor and Income Panel Study (KLIPS) data. The first finding of the study is that specific job search methods, respectively categorized as the indirect and the formal pattern, show the contrasting consequences of causality, as given job searchers'personal attributes and other social factors. Secondly, this analysis confirms that job searchers' education level is the most important factor that influences their behavioral patterns in a consistent manner. Moreover, it is evident in this exploratory study that job searchers' social network (particularly whether to have close ties with relatives of high social rank) is a statistically important factor to influence the extent of job search methods in use, while their fathers' education level also significantly affects the choice of job search patterns.

The traditional way of access to image information is through descriptive keyword searching. However, many studies in image indexing and retrieval have reached a consensus on the difficulties and limitations of text-base image description. This research investigates the feasibility of using visual browsing that is being used comparatively much less than keyword searching. The effectiveness of Keyword access versus visual access were examined through experiments in which participants searched for pictures of specified emotions using different access modes: keywords only, visual browsing only, and the combination of both. It was found that keyword searching was appropriate for clean searches while visual browsing was the effective way to browse many pictures quickly, thus finding more relevant pictures. Findings and results can guide of images retrieval systems, especially the retrieval system of subjective and interpretive information.

향후 무선인터넷 망이 완전히 개방되면 다양한 포털, 컨텐츠 사업자가 등장할 것이다. 이는 사용자에게는 다양한 서비스를 받을 수 있는 장점이 있지만 현재 휴대폰에서의 모바일 인터넷 컨텐츠 탐색 시 발생하는 사용성 문자를 한층 더 증대 시킬 것으로 예상된다. 기존의 연구들은 단일 포털 업체만을 대상으로 연구를 하였기 때문에 여러 포털 업체에서 제공하고 있는 컨텐츠들을 적절히 탐색할 수 있는 기법에 대해서는 아직 연구가 부족하다. 본 논문에서는 시멘틱 웹 구현 기법 중 하나인 토픽맵을 이용하여 효율적으로 모바일 인터넷 컨텐츠를 탐색하고 관리할 수 있는 기법을 제안한다.

Career indecision has long been a phenomenon of interest to parents, faculty, school counselors, and others who advise young adults on their career choices. The earliest work on career indecision focused almost exclusively on the negative consequences that young adults faced as a result of lack of self-insight into their own skills and abilities, lack of specific information about various occupations and labor markets, and fear of commitment to any career path in particular. More recently, researchers have noted that some of the short run negative consequences of early career indecision may ultimately lead to long-term positive consequences, particularly if better person-occupation fit is achieved as a result of young adults' extended search behavior. Extroversion, agreeableness, emotional stability, and openness showed to have negative effects on indecisiveness. In case of lack of job information, only extroversion and emotional stability showed to have negative effects on indecisiveness, and openness showed negative effect. Indecisiveness has negative effect on preparatory job search behavior. Lack of information has negative effect on preparatory job search behavior and active job search behavior.

A Web-based environment has very various and heterogeneous users. The emphasis on their individual characteristics may make it hard to reach the general understanding of how they seek and use information on the Web. The purpose of this study is to find common patterns in information seeking behavior on the Web by analyzing a series of cognitive movement of users in interaction with the Web. Based on Dervin's concept and Timeline interview methodology, this study collected 37 Web experience descriptions from 21 respondents, which consisted of 302 steps. Findings addressed that Web information seeking behavior can be classified into seven types : Starting, Searching, Viewing/B row sing , Examining/comparing, Finding/compiling, Deciding/Acting, and Ending. Movement paths in the seven-type information seeking process showed that user's interaction with the Web was repeated and circulated at the Viewing/Browsing step and that information seeking behavior on the Web was multi-directional and non-linear.

아날로그 기법은 대표적인 공간상세화 기법 중 하나로써, 과거 기상 현상이 미래 재현된다는 가정 하에 목표 시점과 가장 유사한 기상패턴을 보이는 과거 시점을 활용하여 공간상세화를 수행하는 방법이다. 상세화 목표 시점과 가장 유사한 과거 시점을 찾기 위해서는 선결되어야 하는 매개변수가 존재한다. 특히 상세화 성능에 민감한 것으로 알려진 매개변수로는 목표 시점과 유사한 과거 시점 탐색에 활용되는 시공간 범위, 상세화 변수와 역학적 관계를 가지고 있는 종관기상변수, 상세화에 활용되는 과거 시점의 개수 등이 있다. 아날로그 기법의 매개변수를 탐색하고자 하는 시도는 국외에서 여러 차례 진행되어 왔으나, 각 매개변수는 지역의 기상특징에 따라 상이한 결과를 나타내었다. 국내에서는 국외에서 수행한 탐색 결과를 활용하여 공간상세화를 주로 수행하여 왔지만, 보다 높은 성능의 상세화를 수행하기 위해서는 국내 지역에 맞는 매개변수를 활용하는 것이 타당하다. 본 연구에서는 국내 지역에 적합한 아날로그 공간상세화 매개변수를 탐색하고 이를 제시하고자 한다. 탐색된 매개변수는 아날로그 공간상세화 기법뿐만 아니라 다양한 공간상세화 기법에 활용하능한 정보이기 때문에, 연구결과의 활용성이 높을 것으로 판단된다.

최근 들어 저장장치의 발전과 네트워크의 발달로 인하여 대용량의 데이터가 매우 빠르게 증가되고 있다. 또한, 대용량의 데이터에 내재되어 있는 정보를 빠른 시간 내에 처리하여 새로운 지식을 창출하려는 요구가 증가하고 있다. 연속적이고 빠르게 증가하는 데이터를 지칭하는 데이터 스트림에서 데이터 마이닝 기법을 이용하여 시간이 흐름에 따라 변하고, 무한적으로 증가하는 데이터 스트림에서의 빈발항목을 찾는 연구가 활발하게 진행되고 있다. 하지만 기존의 연구들은 시간의 흐름에 따른 빈발항목 탐색방법을 적절히 제시하지 못하고 있으며 단지 집계를 이용하여 빈발항목을 탐색하고 있다. 본 논문에서는 데이터 스트림에서 시간적 측면을 고려하여 상대적인 빈발항목을 탐색하기 위한 새로운 알고리즘을 제안한다. 논문에서 제안하는 알고리즘의 성능은 다양한 실험을 통해서 검증된다.
