이 연구는 기계경비서비스품질이 기계경비고객만족이 고객충성도에 미치는 영향과 전환장벽이 고객충성도에 미치는 영향을 규명하는데 있으며, 조사대상자는 현재 C, S, N, T업체의 기계경비를 이용하고 있는 사업장의 업주들 560명을 대상으로 설문지를 배포하여 조사하였다. 본 연구에서 실증 분석된 연구가설의 결과를 요약하고 고객 전략적 측면에서 시사점을 제시하면 다음과 같다. 첫째, 성별에 따라 기계경비만족도가 대안의 매력에 미치는 영향과 인간관계가 고객충성도에 미치는 영향은 남, 여 간의 차이가 나타났으며, 이용기간 및 연령대에 따라 기계경비서비스품질만족도와 대안의 매력은 차이가 있는 것으로 나타났다. 둘째, 기계경비서비스품질만족도가 높을수록 기계경비고객만족도, 전환비용 및 인간관계에 정적(+)인 영향을 미치는 것으로 나타났다. 셋째, 기계경비고객만족도가 높을수록 전환비용, 인간관계 및 고객충성도에 정적(+)인 영향을 미치는 것으로 나타났다. 넷째, 전환비용이 고객충성도에 미치는 영향에서 전환비용이 높을수록 고객충성도에 정적(+)인 영향을 미치는 것으로 나타났으나, 인간관계 및 대안에 매력에는 유의한 관계가 없는 것으로 나타났다. 이상의 연구결과를 종합해 보면 기계경비이용자들이 기계경비서비스품질만족과 기계경비고객만족도에 대한 인식을 높게 하고 이러한 높은 인식이 전환장벽을 구축하여 높은 고객충성도를 높일 수 있다는 결론을 얻었다. 따라서 기존고객들에 대한 철저한 고객관리와 함께 기계경비서비스품질과 기계경비고객만족도, 전환비용에 대한 투자와 노력이 핵심전략임을 제시할 수 있다. 성공적인 경영을 위해서는 고차원적인 기계경비서비스 품질만족도와 장기고객에게 다양한 고객기반 강화프로그램을 마련하여 고객들에게 실질적인 가치와 편익을 제공함과 동시에 가격적으로 탄력적인 자세를 취하여 높은 전환비용을 마련하여 고객들이 차별화를 직접적으로 지각할 수 있는 각종 커뮤니케이션과 홍보채널을 마련한다면 충성도가 높은 고객집단을 개발하고 유지할 수 있을 것이다.

This paper highlights the economic effects of nuclear power plants standardization in Korea. The major effects of nuclear power plants standardization appear in the reduction of time-related costs. By using this major economic effects of standardization, an optimal plant mix of electric power until the year 2005 is suggested by means of WASP computer model. And the effects between the standardized case and the non-standardized case is compared.

Polysaccharides obtained from Sappan Lignum, Mori Radicis Cortex and Olibanum were examined for their liver protective effects against carbon tetrachloride-and D-galactosamine intoxication in ICR-mice. Hexobarbital sleeping time and serum transaminases (S-GOT and S-GPT) were measured as parameters for the evaluation of liver protective effects. All polysaccharides tested in this experiment showed remarkable positive effects on the prevention of hepatic intoxication with carbon tetrachloride-and D-galactosamine. Much better liver protective effects of polysaccharides were observed in D-galactosamine-liver injuries than in carbon tetrachloride-injuries.

The planar effects on the concrete pavements Is mainly due to the concrete shrinkage, subgrade friction, and thermal expansion or contraction. A complete understanding of analytical behavior of concrete pavement requires the development of computer model, stiffness matrix and equivalent nodal load matrices due to the effects mentioned above. A computer program, INPLANE II, has been written to evaluate the planar effects on concrete pavements. The planar effects determine to what degree the joint open and also help In determining factors which affect the joint stiffnesses and structural behavior of concrete Pavements.

We extended the results of Roy and Guria (2008) to multiple deletions in logistic regression models. Since single deletions may not exactly detect outliers or influential observations due to swamping effects and masking effects, it needs multiple deletions. We developed conditional deletion diagnostics which are designed to overcome problems of masking effects. We derived the closed forms for several statistics in logistic regression models. They give useful diagnostics on the statistics.

Due to complexity of diverse features in urban area, accurate feature extraction is laborious task in aerial and satellite imagery. Especially occlusion by buildings, and image distortion of shadow effects make processing more difficult work. In this study, algorithm was presented to correct of shadow effects in aerial color images. This algorithm enables user to accurately interpretate urban information by correction of shadow effects in aerial color images

Hair growth effects of Sangmosu have been evaluated in C57BL/6 mice. Animals were topically treated with Sangmosu (50 or $100{\;}{\mu}l/mouse$) for 40 days on the back of shaved area. Twenty days after treatment, hair growth effects were significantly observed in both female and male mice. There was no sex difference although 30 days after treatment female mice were shown to be more effective at the dose of $50{\;}{\mu}l/mouse$ than males. These data demonstrate that Sangmosu is very effective in hair growth effects in animals and thus it may be applicable to humans.

In this paper we propose a mixed-effects least squares support vector regression (LS-SVR) for longitudinal data. We add a random-effect term in the optimization function of LS-SVR to take random effects into LS-SVR for analyzing longitudinal data. We also present the model selection method that employs generalized cross validation function for choosing the hyper-parameters which affect the performance of the mixed-effects LS-SVR. A simulated example is provided to indicate the usefulness of mixed-effect method for analyzing longitudinal data.

Aero-optical effects induced by the flow around the optical window degrade the performance of the IR seeker, especially for the hypersonic flow. For the thermochemical non-equilibrium flow, index of refraction model and optical transmission calculation method are developed to predict the aero-optical effects. The optical distortion is discussed for the typical optical widow shape and flow condition. The influence on aero-optical effects is analyzed.

Researchers in marketing, sociology, and economics have been interested in the role of social interactions in consumer choice and consumption behaviors. Social interactions, labeled variously as peer effects, social contagion, and neighborhood effects, have important implications for firms' allocation of marketing efforts. In this research, we test and provide empirical evidence for peer effects in consumers' service usage in the context of gym-going behaviors. Using a detailed individual-level membership and attendance data at one of the largest health club chains in the U.S., we document that a focal member's gym-going behavior is influenced by the behaviors and characteristics of the peers at the same branch
