This study examined service failure and recovery of domestic ethnic food restaurants based on a model of the repercussions of service failure dealing with seriousness and control and the cause-and-effect relationships among the variables relevant to the quality of relationships -trust, satisfaction, and loyalty. This study provides valuable information for Korean restaurant managers regarding food service failure and response plans by collecting data from actual Japanese tourists visiting ethnic food restaurants. The results suggested that it is important to develop a strategy to present the distributional fairness to customers who recognize the seriousness of service failure to control the situation promptly. These results can be used to establish more systematic business plans, improving customer management and firm performance. The advantage of this research is that it is time for substantial research data on the booming domestic restaurant industry and service quality to overcome the current recession and grow and solidify the current restaurant market.

The dimensional accuracy of a final product is mainly affected by elastic die deformation during the forging and elastic recovery after the ejection in cold forging process. The investigations on elastic recovery are not so much as those of elastic die deformation. The elastic recovery can be determined by using the elastic-plalstic finite element analysis, but, this method has some limits such as poor conver- gence and long computational time, etc. In this paper, a theoretical analysis for predicting the elastic recovery of a final product in axi-symmetric forging process by using the rigid-plastic finite element method is presented. The rigid-plastic finite element analysis of a cold forward extrusion process involving loading, ejecting process is accomplished by rigid-plastic FE code, DEFORM. The effect of elastic die deformation on the final product dimenmsion is also considered. The calculated elastic recovery is compared is compared with the analysis result of elastic-plastic FE code.

There have been raised other environmental issues related to remediated soils piled up in numerous carry-out processing facilities because a considerable quantity of them have been produced every year, but most of them have not been relevantly reused or recycled. Thus, this article reports the trend of researches on the development of techniques to restore the quality of remediated soils to activate their reuse and recycling. Firstly, the tendency of change in soil properties through remediation processes was looked over, and then the degradation of soil quality was characterized according to the type of remediation processes. Besides, the direction of policy to promote the reuse and recycling of remediated soils was introduced, and finally, the future works needed were suggested. This article was prepared based on the results of the survey of domestic and foreign literature. A number of literature were reviewed to scrutinize the change of soil properties due to remediation processes and diverse techniques for the amendment and restoration of remediated soils. Furthermore, the policies related to the reuse and recycling of remediated soils were arranged with the reference of the first and second versions of the Soil Conservation Master Plan of Korea. The literature survey focused on three kinds of remediation technologies, such as land farming, soil washing, and thermal desorption, which were most frequently used so far in Korea. The results indicate that the tendency of change in soil properties was significantly different depending on the type of remediation processes applied, and the degradation characteristics of soil quality were also totally different between them. The soil amendment and restoration can be categorized as three techniques depending on the type of substances used, such as inorganic, organic, and biological ones. Diverse individual materials have been used, and the soil properties improved or enhanced were dependent on the type of specific materials utilized. However, few studies on the restoration of soil qualities degraded during the remediation processes have not been carried out so far. The second Soil Conservation Master Plan states the quality certification and target management system of remediated soils, and it is expected that their reuse and recycling will be facilitated hereafter. With the consideration of the type of remediation processes implemented and public utility, the restoration technologies of remediated soils should be developed for the vitalization of their reuse and recycling. Besides, practical and specific measures should be taken to support the policy specified in the second Soil Conservation Master Plan and to promote reuse/recycling of remediated soils.

반도체 device의 성능을 향상시키기 위하여 패턴은 더욱 더 고 집적화 되고 배선 또한 다층배선 구조를 가지게 되었으며 요구되는 선폭 또한 더욱 미세화 되어 CMP 공정이 도입되게 되었다. 이러한 CMP 공정에 사용되는 소모품으로는 크게 세 가지의 중요한 부분으로 나눌 수 있다. 그것은 slurry와 pad, conditioner이다. 그중에 pad conditioning 공정은 CMP 공정시 pad의 마모에 따라 감소하는 removal rate(RR)값을 회복시키기 위한 공정으로 마모된 pad의 표면을 활성화 시켜주는 중요한 공정이다. 하지만 pad conditioning 공정을 장시간 진행하게 되면 conditioner 표면에 오염물이 발생하게 되며, 오염물로 인하여 wafer표면에 scratch 및 defect을 발생시키는 원인이 될 수 있다. 이러한 문제점을 보완하기 위하여 conditioner의 표면을 변화시켜 공정중의 오염이 발생하지 않도록 하는 것이 중요하다. 본 논문에서는 oxide CMP 실험을 통하여 conditioner표면에 오염물이 발생함을 확인하였으며 energy dispersive spectroscopy(EDS) 분석을 통하여 주오염물의 성분이 oxide slurry중 silica임을 확인하였다. Conditioner의 표면을 소수성으로 만들기 위하여 self assembled monolayer(SAM) 방법을 이용하여 표면에 코팅을 하였으며, 소수성 박막이 코팅된 conditioner와 코팅되지 않은 conditioner의 비교 실험을 통하여 오염 정도를 비교하였다.

This study attempts to analyze relational structures among service failure-related variables after the moderation of fairness in the beauty service industry with the following purposes: First, it aims to review and investigate service failure & service recovery strategies, non-switching intentions after recovery, revisit intention, the intent to provide word-of-mouth recommendations and previous studies on service failure and recovery in the beauty service industry. Second, it targets the analysis of the role of fairness as a variable that moderates relations between service recovery strategies and post-recovery satisfaction in the beauty service industry. For this, the following research method was used: This study has investigated the effect of service failure and its recovery strategies (behavioral recovery strategy, psychological recovery strategy, monetary recovery strategy) on customer satisfaction for beauty service users and used the Structural Equation Model (SEM) to further analyze and verify the effect of the satisfaction on post-satisfaction behavior (non-switching intention, repurchase intention and the intent to provide word-of-mouth recommendations). The SEM was divided into a measurement model and structural model to determine if the model is appropriate and estimate the parameters of the path coefficient. In addition, this study examined to see if fairness (procedural fairness, distributive fairness and interactive fairness) works as a moderating variable while the service recovery efforts affect customer satisfaction. Then, the role of service recovery strategies, targeted to satisfy the customers who were dissatisfied because of service failure, were investigated. In addition, its effect on post-satisfaction behavior was analyzed from the structural aspect, and the moderating role was examined as well. Then, the role of the service recovery strategy, which can be used to satisfy dissatisfied customers, was examined, and the effect of the satisfaction on customer behavior was analyzed from a structural perspective. In addition, the moderating role of fairness was tested. As a result, this study is significant in that it helps service providers formulate service recovery-related strategies.

가스 상태의 반응 공정을 이용하는 반도체, 플라즈마, 연소 및 촉매를 이용한 유해가스처리와 대기환경 등에서는 반응을 주도하는 활성기(radical)의 역할 그리고 극미량(sub-ppm 수준)으로 존재하는 유해가스 성분등을 실시간으로 추적하는 것은 매우 중요하다. 현재 사용되고 있는 비 광학적 미량 가스 측정 장비들은 측정 대상 가스성분과 측정 장치의 프로브 사이의 물리적인 접촉이 요구되므로 감지시간이 늦고, 프로브 오염에 따른 hysteresis, 회복시간(recovery time)의 지연, 활성(부식성) 가스 샘플에 의한 감지기능 저하 등을 유발한다.
