This paper analyzes how the service quality affects customer satisfaction and loyalty, focusing on a franchise restaurant company 'Wonhalmoney Bossam'. The result shows that store locations and food cost of the menu, as an additional quality formation factor, influence customer satisfaction and loyalty rather than the main quality formation factors. This study strongly suggests the marketing preparation of menu price and the choice of locations are most significant as an additional factor. Therefore, Korean food restaurants should develop their marketing strategies from the customer's point of view, and reasonable price setting and menu selection with appropriate location will create customer satisfaction and revisit.

This present study has dealt with the effect of surfactant on the freezing of aqueous solution Sodium chloride aqueous solution was used to measure the effect of surfactant and the main parameters of this experiment were temperature of bath, revolution of stirrer. and the radial velocity of NaCl solution. The acquired main conclusions are as follows; 1) the lower super-cooling temperature make hardly to attach the ice on beaker, 2) the size of ice become smaller to add the surfactant, 3) the ice packing factor increase with increasing of stirrer revolution.

Currently axial flow compressor is used primarily in a large power generation gas turbine. In this paper,the main factors to be considered when designing a axial flow compressor were compared to those of a small power generation gas turbine(DGT-5). The main design parameters was examined in the aspect ratio, solidity, as well as reaction, diffusion factor, incidence angle, etc. The results in case of a small compressor are showed a regular pattern but there were not found any specific design patterns for a large class compressor.

The purpose of the resent research is to investigate the characteristics of sound insulation at the circular voided concrete slab in the multi-housing. In order to do this research, the method for field measurement of floor impact sound level was used following the Korea Standard F2810-1996. For the multi-housing, three kinds of circular voided concrete slabs are used to measure the characteristics of sound insulation.The results are as follows; 1.The main factor affecting the characteristics of sound insulation at the circular voided concrete slab in the multi-housing is sound-absorbing materials in the circular tube. 2. The main factor to effect the difference of sound pressure level is circular tube in the concrete slab. 3. The forms of circular tubes effect the characteristics of sound insulation at the circular tube. 4. Sound Pressure Level resulting from the piping direction of circular tubes in little different to octave band level.More study will be needed about the depth and distance of sound insulation materials, and the components of sound insulation materials for the multi-housing.

The main purpose of this study is to obtain information on users' socio-economic characteristics, pattern of main use activities, and visit motivation in recreation forests. From June to September in 1994, respondents were selected 548 adults more than 18 years old from 6 recreation forests which were classified 3 recreation forest types as 2 recreation forest in national forest, 2 in public forest, and 2 in private forest. Analysis of data was conducted through frequency and factor analysis. The most of noticeable characteristics of users were rather 30's age group, high education level, company workers, city residents. The major preference activities in recreation forest were resting, enjoying green shower, and walking. In 24 items of visit motivation, resting, releasing stress, enjoying in a cool forest & valley, and contacting close to nature were high preference, while buying special product, and contacting close to nature were high preference, while buying special product, having enough and to money, observing wildlife, and training body & mind were low preference. The remarkable difference in 3 recreation forest types didn't present. Eight dimensions of motivation were classified through factor analysis.

The focus of this study is placed on the enhancement of flatness for the shielded slot plate, one of main components of the MCFC stack. The shielded slot plate is to get curvature during manufacturing process since it is produced by forming operation from only one side of it. Therefore, a correction die is proposed to place just after the main die to apply unbending on the curved plate to get almost flat product. In the design for the correction die, four kinds of design factors are selected to study which factor is the most influencing one affecting the flatness of the plate. From the experimental results using Taguchi method, it has been revealed that the Young's modulus of urethane die is the most critical factor.

Recently, There have been many attempts to optimize energy usage in buildings and houses using Information Technology(IT) and the typical implementation can be found in Intelligent Building and Zero Energy Building. These kinds of buildings need to forecast the building loads, estimate the capacity requirement for power supply, and decide the capacity of the main transformer of the building. Currently, the capacity of the main transformer has been decided just using typical load estimation method not considering the load characteristics and patterns. In this paper, we propose a new load estimation method considering the load characteristics and patterns of the builiding. The proposed method was applied to actual mail center and verified the feasibility of application to actual design of buildings.

Wet-work can be defined as activities where workers have to immerse their hands in liquids for >2 hours per shift, or wear waterproof (occlusive) gloves for a corresponding amount of time, or wash their hands >20 times per shift. This review considers the recent literature on wet-work exposure, and examines wet-work as a main risk factor for developing irritant contact dermatitis of the hands. The aim of this paper is to provide a detailed description of wet-work exposure among specific occupational groups who extensively deal with water and other liquids in their occupations. Furthermore, it highlights the extent and importance of the subsequent adverse health effects caused by exposure to wet-work.

The main purposes of this study were to assess coffee shop use and to identify the influence of physical environment of a coffee chop on customer behavioral intention. The survey was administered from April to May 2011, targeting twenties college students in Seoul, Gyeonggi Province. A total of 174 copies of the questionnaire were collected for the data analyses such as frequency test, descriptive analysis, chi-square analysis, reliability test, factor analysis, ANOVA, Duncan's multiple range test and multiple regression analysis using SPSS 17.0 program. The main results of this study were as follows: The number of visits was once or twice a week. Students went with their friends to the coffee shop. Most of the students answered that they visit the coffee shop at any time. The main purpose of visit was to have time to relax. The main source in choosing a coffee shop was recommendation from others. The main criterion for the selection of the coffee shop was atmosphere. Americano was a favorite drink. Coffee was drunk with a cake. Expenditure per visit was 3,000~5,000 won. The choice of the coffee shop was selected by the student. The factor analysis identified seven underlying dimensions of coffee shop physical environment perceptions (seating comfort, attractiveness, cleanliness, harmony, ambient condition, congestion, amenity) and one dimension of customer behavioral intention. Through multiple regression analyses, four determinants (attractiveness, cleanliness, amenity, ambient condition) were found to have the greatest impact on customer behavioral intention.

본 연구에서는 다단연소사이클 액체로켓엔진 파워팩에 대해 시동과정에서의 동특성 변화를 예측하였다. 시동특성과 관련된 주요 인자 중 밸브 개방시점에 대해 분산값을 정의하고 몬테카를로 방법을 적용하여 이들이 시동특성에 미치는 영향을 살펴보았다. 해석 결과, 연소기 연료 밸브 개방시간 및 시동터빈 종료시간이 시동특성과 관련된 주요 변수임을 확인하였다. 연소기 연료 밸브 개방시점과 시동터빈 종료시점을 분리하여 해석한 결과, 연소기 연료 밸브 개방시점이 시동특성과 매우 밀접한 관련이 있음을 확인하였고 안정적 시동을 위해서는 시동터빈 작동이후 약 1초 이전에 밸브가 개방되어야함을 알 수 있었다. 이를 통해 안정적 시동을 위한 시동 시퀀스 설정이 가능함을 확인하였다.
