  • Service quality research has been the subject of service studies for many years. This study is an exploratory study to improve the service quality measurement factor, and the research has been carried out reflecting the nature of the service; relationship quality, interactivity, horizontality, and harmony. Also, among the developed service quality measurement factors, the research model is reconstructed considering the major factors such as environmental quality, result quality, and convenience quality. Relationality and interactivity redesigned the quality factor, which is called interactive quality. The redesigned service quality factors consisted of interaction quality, result quality, environmental quality, convenience quality, harmonious quality, and horizontal quality. Experimental group evaluation was conducted on the quality factors and 18 measurement items were derived. A questionnaire was conducted to verify the validity of the 18 items. As a result of the questionnaire analysis, 6 factors and 15 items among the 18 items of service quality measurement factor were found valid. The six factors for the service quality measurement presented in this study are the results of the early stage research, but they can be used to improve the service quality factor in the future. However, this is significant because it reflects the characteristics of services that are consistent with the service economy. In particular, the horizontal quality and harmony quality factors are new factors not mentioned in the previous studies and need to be verified through further detailed studies. Further research is needed to improve the service quality measurement factors reflecting the nature of services and the characteristics of new services.

  • This study was conducted for analyzing the contribution factors on ozone concentrations and its long term trends in each major city and province in Korea through several statistical methods such as simple linear regression, generalized linear model, KZ-filer, correlation matrix, Kringing method, and cluster analysis. The overall ozone levels in South Korea have been consistently increasing over the past 10 years. The ozone concentrations in Seoul, the biggest city in Korea, are the lowest in all areas with the highest increasing ratio for $95^{th}%$ ozone. It is thought that the active photochemical reaction could affect the higher ozone concentration increase. On the other hand, the ozone concentrations in Jeju are the highest in Korea with the highest increasing ratio for $5^{th}%$, $33^{th}%$, and $50^{th}%$ ozone. It is also thought that the weak $NO_x$ titration could be the reason of higher ozone concentrations in Jeju. In case of Jeju, transport related factors is the major factor affecting the ozone trend. Thus, it is assumed that the variation of ozone trend of Asian region affecting the ozone trend in Jeju, where domestic ozone photochemical reaction is less active than urban area. It is thought that the photochemical reaction plays the role of increasing of ozone concentrations in the urban area, even though the LRT affected on the increase of ozone concentrations in non-urban area.

  • Quality control of Argo(Array for Real-time Geostrophic Oceanography) data is crucial by reason that salinity measurements are liable to experience some drift and offset due to biofouling, contamination of sensor and wash-out of biocide. The automated Argo real-time quality control has a limit of sorting data quality, so that WJO program is adopted as standardized method of Argo delayed mode quality control (DMQc) in the world that is a precise quality control method. We conducted DMQC on pressure, temperature and salinity measured by Argo floats in the Pacific Ocean including expert evaluation. Particularly, salinity data were corrected using WJO program. 4 salinity profiles of Argo delayed mode were compared with nearby in situ CTD data and other Argo data in deep layer where oceanographic conditions are stable in time and space. The differences of both salinities were lower than target accuracy of Argo. As compared with the difference of salinities before DMQC, those after DMQC decreased by 60-80 percent. Quality of delayed mode salinity data seemed to be improved correcting salinity data suggested by WJO program.

  • It is one of the most critical steps identifying impaired waterbodies exactly in the selection of target water quality indicators for the management of Total Maximum Daily Loads (TMDLs). Excess ratio and excess level were applied and analyzed by the stream zone basis in order to evaluate water impairment for Nakdong, Geum, Youngsan and Seomjin rivers. Each river basin was divided into stream zones in the light of its watershed and waterbody characteristics. Selected water quality parameters discussed in this study were pH, DO, BOD, COD, SS, T-P, T-Coli and F-Coli. The excess ratios of the water quality parameters were used to discriminate water bodies that did not meet water quality standards. The excess levels were used to classify the degradation of water quality. The excess ratios and the excess levels to the water quality criteria of the medium influence areas were used for each stream zone. The results indicate that the excess ratios and the excess levels are varied on the stream zone in each river basin. Three parameters, pH, DO and SS, met water quality standards in all stream zones. The other five parameters indicated very high excess ratios in most waterbodies, and especially T-P and T-Coli revealed to be very high excess levels in some waterbodies. These parameters could be considered as major target indicators for the management of TMDLs.

  • Although researchers have, during the past decade, become increasingly interested in customer satisfaction customer reaction, and service quality issues, very little of research has devoted to the family restaurant. Family restaurant industry is among the fastest growing sectors of the tourism market. This paper discusses the importance of the family restaurant product and service quality, and presents the relationship among service quality, customer satisfaction, and customer reaction. The literature supports the value of family restaurant's service quality and relation between service quality and customer reaction. Exploratory study examined customer's satisfaction with service quality components and customer's reaction with satisfaction. The survey was conducted in four phases; service quality, customer reaction(satisfaction, repurchase intention, and word of mouth), restaurant information, general profile of customer. The results of the study show that service quality(product's quality, physical character) provided family restaurant customer with the overall satisfaction, and service quality affected on customer reaction(repurchase intention, positive word of mouth). Also overall satisfaction affected on repurchase intention and positive word of mouth.
