In recent years, service delivery systems employing a self-service approach have been rapidly spreading. Since a self-service system provides a lower product price, it attracts more customers. However, some system managers are still hesitant to accept a self-service system, because there is no systematic model to predict its performance. Therefore, this research attempts to provide a systematic and quantitative model to predict the performance of a self-service system, focused specifically on a self-service gas station. Under this model, the traditional queuing theory was adopted to describe the general self-service process, but it is also assumed that some changes occur in both the customer arrival rate and the service performance rate. In particular, the price elasticity was introduced to capture the change in the customer arrival rate, and the existence of learning effect and helpers were assumed to design the changed service performance rate. Under these assumptions, a simulation model for a self-service gas station is established, and three performance measurements, such as average number of customers, average waiting time, and Utilization are observed, depending on the changes in price difference and helper-operating time. In this research, the optimal operation strategy for price differentiation and helper-operating time is proposed in accordance with the level of the customer learning rate. Although this research confines the scope of the study to the self-service gas station model, the results of this research can be applied to any type of self-service system.

This research investigates the present situation of petroleum market and the potential strategy which help gas station obtain competitive advantages. Specifically, this research chooses five factors (product quality, service, price, multi-function, easy entrance) which are believed to be extensively related to repurchasing intention. The findings are as follows; First, four factors associated with gas station choice (product quality, service, price, multi-function) are related to repurchase intention except easy entrance. Second, sex and age have moderating effects between factors and repurchase intention. To keep and preoccupy new customers, the administrators of petroleum industry and gas station should establish sales/administration strategies considering these above.

The Service sector has increased dramatically in importance over the last decade, both internationally and in the Korea. Deregulation of services, growing competition, fluctuations in high quality demand, and the application of the Information Technologies are presenting a considerable challenge to service companies. In gas or oil companies are exposed to foreign competitions, price and promotion competition with other companies. Usually Service Quality includes five dimensions: Reliability, Responsiveness, Assurance, Empathy, and Tangibles. Customers use these five dimensions to form their judgements of service quality, which are based on a comparison between expected and perceived service. The intention of this thesis is to study on the effect of Service Quality upon the Customer Satisfaction in gas or oil station, based on SERVQUAL.

CNG 충전소에 대한 사고영향평가(CA) 분석을 실시하였고 이미 고압법에 의해 설치되어 있는 LPG 충전소에 대한 CA를 실시하여 서로 비교하였다. CNG 충전소와 LPG 충전소에 대한 누출 확산 및 복사열의 영향평가 결과 연소하한계에 도달하는 거리는 CNG 충전소가 LPG 충전소에 비해 약 1.5배 컸으며, 복사열의 경우 공정장치에 손상을 줄 수 있는 복사열량이 CNG 충전소에서는 나타나지 않았으나 LPG 충전소의 경우 37.5 $kw/m^2$에 해당하는 복사열이 12.6 m 반경으로 나타나 주변의 상가지역까지 큰 영향을 미칠 수 있는 것으로 나타났다. 또한, 목재를 태울 수 있을 정도의 복사열량인 12.5 $kw/m^2$은 LPG 충전소가 CNG 충전소에 비해 약 3배 가량 큰 것으로 나타났다.

Purpose - This study conducts an empirical analysis on gasoline pricing of Korean retail gas stations focusing on spatial effects. Unlike previous studies, the study uses an official land price for a proxy of the importance of location, and also allows the spatial effects from other competing gas stations as well. Research design, data, and methodology - In collection of data, we obtain more abundant data than those of previous studies. The gasoline prices used in the study are 909,084 observations as daily data from January 1 to July 31 of the year 2016. A proxy for the land price is collected by linking official public land price data with address information on each gas station. For the estimation, the study employs the Panel Spatial Dubin Model to make the best use of the collected location information. Results - As expected, spatial properties of gas stations have significant effects on the gasoline price. As the price per square meter increases by 100 thousands won, the price of gasoline rises 9 won per liter. Among other characteristics, the price increases by 16 won per liter if the station has a convenience store, and about 5 won if it has a car wash service. Gasoline price in Singapore accounted for 26% of variations in domestic gasoline prices. SK Energy and GS Caltex are the top brands in terms of price. The study also finds prices and other important properties of competing gas stations have significant effects on others' prices. Prices of competing gas station have a positive relationship with those of others. If a competing gas station raises the price, the gas station also raises the price, and lowering the price lower the price. Among brands, GS Caltex has the greatest downward pressure on nearby gas stations. Conclusions - The study confirms that location value of gas stations affect their gasoline prices, and the prices of the competing gas stations also have a significant effects on their prices. It suggests that the prices in the competing retail areas tend to be synchronized with each other.

Objectives : This study was performed to evaluate BTEX exposure to gas station service attendants and the critical affect of benzene and MtBE airborne concentration. Methods : the degree of exposure to airborne BTEX and MtBE was examined in the service attendants at seven gas stations across the country during a summer season. The TWAs(time-weighted averages) of atmospheric concentration of substances in personal and area samples, were calculated. The component ratio of BTEX and MtBE in the samples of bulk gasoline from each station studied was also measured. Results : The airborne concentrations of BTEX and MtBE showed a lognormal distribution and The TWA concentrations of benzene in personal samples from each station were 0.089 ppm - 0.18 ppm, and those of toluene were 0.097 ppm - 0.2 ppm. The average TWA concentrations of xylene and ethyl benzene was 0.03 ppm and 0.001 ppm, respectively. The TWA concentrations of MtBE were 0.4 ppm - 1.3 ppm. The volume concentrations of MtBE, toluene, ethyl benzene and xylene in the bulk gasoline samples were 3 - 7.4 %, 3 - 12 %, 0.64 % and 1.5 - 10 %, respectively. Conclusions : The benzene concentration was detected to exceed the ACGIH threshold benzene level of 0.5 ppm, in one of 74 personal and area samples. MtBE, a substitute for aromatic compounds such as benzene in gasoline, was found to bring about a greater chance of exposure to carcinogen, due to its high vapor pressure and carcinogenicity.

This experiment was conducted to investigate the effect of fermented spent mushroom substrate (FSMS) on growth performance, blood profile, intestinal microflora and ammonia gas production of feces in broiler chickens. A total of three hundred sixty, 1-day-old male broiler chicks (Ross) were randomly divided into 3 groups with 6 replicates of 20 birds each. The treatments were control (free FSMS), 15% FSMS (basal diet with 15% FSMS) and 30% FSMS (basal diet with 30% FSMS). The final body weight and body weight gains were slightly improved in 30% FSMS than control (P<0.05). Feed intake and feed conversion were significantly improved as compared to those of the control groups. The Leukocytes of blood serum in FSMS groups were significantly decreased as compared to those of control groups. There are no significant differences among the groups in the contents of albumin (ALB), total cholesterol (TCHO), glucose (GLU), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in blood serum. The content of total glucose (TG) in 30% FSMS containing dietary groups was significantly decreased as compared to that of the control groups. The content of HDLC in 30% FSMS containing dietary groups was significantly increased as compared to that of the control group. The number of lactobacillus in the intestinal microflora were significantly increased in chicks fed FSMS groups. The ammonia gas production in FSMS groups was siginificantly decreased as compard to that the control groups. These results indicated that dietary FSMS exerted growth performance for feeding broiler.

This study examined the relative effects of weekly and daily group feedback on the customer service behaviors in a gas station. Participants were four employees providing full services to the customers. Four target service behaviors, which were identified from the job description for the employees, served as the dependent variables. The data were collected by a supervisor. The independent variable was the frequency of group feedback on the four service behaviors: weekly and daily group feedback. An ABC within group design was adopted. After baseline (A), the weekly group feedback condition (B) was introduced. In the next phase, the daily group feedback condition (C) was introduced. Both weekly and daily group feedback were presented in a graph form and posted at a conspicuous location. Results showed that both weekly feedback and daily feedback conditions were effective in increasing the target behaviors. And, there was difference in the effects between the two conditions.
