This study examines whether product promotions are influenced by the market standing of promoted products, using social comparison theory (upward versus downward comparisons). It is hypothesized that people in possession of a product that is inferior to the one on promotion express less discomfort about the promotion and use the information more than do people in possession of a superior product. People in possession of an inferior product may also exhibit more positive attitudes toward the product on promotion, but may show poorer attitudes toward their own possessed product than do people with a superior product. This is because people in an inferior socioeconomic position show a strong motivation to improve themselves through upward social comparison, whereas people in a superior socioeconomic position maintain a strong sense of superiority in downward social comparison, which suggests strong endowment effects. The findings mainly support the hypotheses, and suggest that sales promotions are more effective for people who currently own an inferior product, but not for people with a superior product, who have a strong motivation to maintain their sense of superiority. The findings also imply that, in order to attract consumers in the superior market, managers for inferior products need to turn to methods other than sales promotions, which may include introducing a new brand or sub-brand, or emphasizing luxury and modern features. In contrast, managers for superior products may emphasize product functions and attributes of superior products in their promotions, as people with inferior products may consider such information as benefits of the superior products.

In many practical machine learning and data mining applications, unlabeled training examples are readily available but labeled ones are fairly expensive to obtain. Therefore semi-supervised learning algorithms have attracted much attentions. However, previous research mainly focuses on classication problems. In this paper, a semi-supervised regression method based on support vector regression (SVR) formulation that is proposed. The estimator is easily obtained via the dual formulation of the optimization problem. The experimental results with simulated and real data suggest superior performance of the our proposed method compared with standard SVR.

In this paper, we present forecasting ozone concentration with decision support system. Since the mechanism of ozone concentration is highly complex, nonlinear, and nonstationary, modeling of ozone prediction system has many problems and results of prediction are not good performance so far. Forecasting ozone concentration with decision support system is acquired to information from human knowledge and experiment data. Fuzzy clustering method uses the acquisition and dynamic polynomial neural network gives us a good performance for ozone prediction with ability of superior data approximation and self-organization.

Stress affects the type of adaptation required for each case and the type of social support is also different. In order for social support to have a buffer effect on stress, we want to understand how to measure social support and support according to specific stress situations. Therefore, this study examines coping behaviors of community service workers exposed to these job stresses and examines the effect of support system (family support, peer support, superior support) on coping behavior. The purpose of this study is to investigate the effects of stress, coping resources and coping behaviors of community service workers. In this study, self - report method was used to investigate the questionnaire using structured questionnaires. In this study, the statistical program was used for data analysis and hierarchical regression analysis.

본 연구에서는 산학협력 우수 전문계고 지원 사업에 대한 운영 실태를 조사하고, 비교 분석하여 그 결과를 바탕으로 사업 추진에 바람직한 방향을 제시할 수 있는 기초자료를 제공하고자 하였다. 연구 대상 학교는 2005년에 선정된 20개교 중 지역 및 사업의 특성을 고려하여 10개의 대상 학교를 선정하여 최초 사업 추진계획서와 중간 보고서를 중심으로 관련 보도자료 및 논문을 통하여 자료를 수집, 분석하였다. 연구결과 첫째, 외부전문기관과 협약에 의한 위탁교육은 해당학교가 추진하는 사업 분야와 직접적으로 관련 있는 위탁교육 기관을 선정하여 협약을 통한 시설교육 중심으로 프로그램이 진행되었다. 둘째, 산업체 현장 체험학습 교육프로그램 운영은 참여 학과와 관련된 전시회 참여, 산업체 전문 인력 초빙 강의, 현장 견학 등 다양한 분야에 걸쳐 운영되었다. 셋째, 산학겸임교사 및 외부 전문 강사 강의 현황은 산학겸임교사 채용에 어려움으로 인하여 외부 전문 강사 강의가 교과전문분야를 중심으로 활발하게 운영되었다. 넷째, 졸업자 진로현황은 학교전체 및 사업에 직접 참여한 학생의 취업률이 진학률보다 낮게 나타났다.

In this paper, to support a QoS level appropriate to the user in Wireless Home Network based Wireless LAN, we propose a QoS support architecture which includes Wired Network and Wireless Network. Actually, an important problem to support QoS in Wireless Home Network is approached not only on a MAC level in Wireless LAN but also on a integrated method to combine Network layer with Datalink layer. By applying the integrated QoS support method, it is possible to provide QoS support architecture using a Wireless LAN terminal with a minimum changing, and the proposed scheme has advantage of QoS support method, which is more superior than a existing scheme to support QoS in MAC level of Wireless LAN. Simulations results show that overall performance of the proposed scheme can be improved.

Purpose: This study identified the influence of hotel workers' emotional labor and social support on their intentions to change jobs. Methods: Study participants were 437 workers from seven hotels in Korea who consented to the survey. Among them, insufficient responses from 21 participants were excluded, as well as 107 responses from workers with workloads of under one hour of face to face work. Thus, 309 hotel workers were included in the final analysis. A multivariate regression analysis was used to identify factors influencing the hotel workers' intention to change jobs. Results: The intention to change jobs was high when external behavior was shown, and workers who received social support from a superior exhibited low intention of changing jobs. Conclusion: The study results show that the most influential variables of turnover intention are external behavior and the support of a superior. It is therefore important to educate managers on personnel management methods for reducing external behaviors so that the rate of job changes by hotel workers can be reduced. It is also necessary to prepare and manage measures for strengthening the support system by workplace superiors.

전통적인 리더십 이론들은 공식적 권한을 가진 직책자를 리더로 전제해 왔다. 그러나 최근의 경영환경은 비직책자인 팀원도 리더십을 발휘해야하는 상황에 있다. 이에 본 연구에서는 팀원의 리더십과 그 효과성을 검증하고자 했다. 또한 팀원의 이슈리더십 행동의 강도를 조절하는 요인으로서 상사지원의 조절효과를 검증하였다. 분석결과 비직책자인 팀원의 이슈리더십은 오디언스의 리더수용과 팀 성과에 정(+)의 영향을 미는 것으로 나타났다. 그러나 팀원의 이슈리더십과 리더수용 간의 상사지원의 조절효과는 통계적으로 유의하지 않았고 이슈리더십과 팀 성과 간의 상사지원 조절효과는 부(-)적인 관계임을 새로 발견 했다. 본 연구는 팀원의 리더십과 그 효과성을 실증하고, 일반적인 기대와는 달리 상사의 지원이 오히려 팀원의 리더십 발휘를 저해하는 요인임을 발견하였다는 것에 의의가 있다.
