The purpose of this study is to investigate the structural relationship between resort selection attributes, emotional responses, and empirical values of scuba diving participants. The general population who enjoys scuba diving in Korea was selected as the population. Using the convenience sampling method, 553 of the 600 questionnaire samples were extracted as the final valid sample. For data processing, frequency analysis, exploratory factor analysis, and Cronbach's α test were performed using SPSS 23, and confirmatory factor analysis and structural equation model analysis were performed with AMOS 18. The results are as follows: First, among the sub-factors of selection attributes, equipment, facility environment, and diving point showed a positive effect on emotional response, but staff service did not have any significant effect. Second, the emotional response positively affected by the selection attribute showed a positive effect on all factors of service excellence, consumer utility, fun value, and aesthetic value of empirical value. Therefore, scuba diving resort managers must recognize the importance of equipment, facility environment, and diving point among these selection attributes of customers. And to satisfy the customer needs the resort must accurately identify the needs for diving equipment, facility environment and diving point. Various methods for this should be explored through the needs of the identified customers, and efforts should be made to provide safe equipment, comfortable facilities, and various diving points.

The purpose of this study is to identify the effects of a company's response strategies (response type, communication style, and response sincerity) on customer's brand attitude and purchase intentions. A fictional Facebook fan page containing 6 separate scenarios was developed based on actual customer reviews and company responses observed on Facebook restaurant fan pages. Participants were recruited from Amazon's Mechanical Turk (MTurk). A total of 202 responses were obtained; 185 responses were analyzed after deleting insufficient responses. The results of MANOVA found that an accommodative response leads customers to have a more favorable attitude towards a brand and have stronger purchasing intentions. In addition, customers who perceive the company's response to a negative review as sincere are more likely to have a positive brand attitude and purchasing intentions, as compared to those who perceive it as either insincere or neutral.

Medical personnek are one of several groups that have been reported to have a high incidence of hepatiris B. It is also thought that the occurrence rate of hepatitis B surface antigen(HBsAg), aserologic marker for hepatitis B virus(HBV), is expected to be high in the dental personnel who are frequently exposed to the blood and saliva of the patients. Although many studies have been done to determine the HBsAg status of virus groups, limited investigations have been performed on dental personnel, especially in this country. The main purpose of this study was to identify HBsAg positivity among dental students, interns, and residents who would be expected to be a high risk group of hepatitis B infection. Screening test for HBsAg of a dental school population was performed by indirect hemagglutination(IHA)in 1982. The results were as follows : 1. Thirty four out of a total 362 persons(9.4%)tested in the study had positive response for HBsAg in their serum samples. 2. Twenty seven out of 320 dental students(8.4%)had positive for HBsAg, and in Senior class 12 out of 82 dental students (14.6%)had positive response that was the highest incidence among dental students group. 3. Seven out of 42 interns and residents(16.7%)had positive for HBsAg, and it was the highest incidence in this dental school population.

Currently, convenience stores, which are naturally located within a 1-minute walk, are easily accessible, so customers can easily purchase the items they need, and now they are indispensable places for people. In line with modern society that focuses on buying and selling goods quickly and easily, such as 'convenience' and 'quickness', convenience stores also have been changing by marketing such as home-delivery service and storage of fresh products, not just simply selling goods. In addition, by utilizing application software, we can use everything with one smartphone that we use a lot, in order to provide reservation delivery, pickup, and subscription services. In this study, we conducted experiments focusing on the factors of convenience store service quality and users using convenience stores, and examined how these experiments affect behavioral intentions of customers through their emotional responses. As a result, it was confirmed that empathy had a positive (+) effect on the pleasure of customers, and reliability had a negative (-) effect on arousal. In addition, it was found that empathy had a positive (+) effect on arousal, and responsiveness and empathy had a positive (+) effect on dominance. Finally, it was found that pleasure and dominance had a positive (+) effect on the loyalty of customers. In this study, we intend to provide basic data on existing or future convenience stores.

Recent studies suggested that the ovarian cancers with negative excision repair cross-complementation group 1 enzyme (ERCC1) expression have a better response to platinum-based chemotherapy than those with positive ERCC1 expression. The objective of this study was to evaluate whether ERCC1 expression is associated with response to platinum-based chemotherapy in ovarian cancers. MEDLINE, PubMed, Web of Science and CNKI databases were used for searching studies relating to ERCC1 protein expression and response to platinum-based chemotherapy in ovarian cancers. Statistical analysis was based on the method for a fixed effects meta-analysis. Pooled odds ratios (ORs) with 95% confidence intervals for ERCC1 protein expression and response to platinum-based chemotherapy were generated. Publication bias was investigated with Begg's test. Five studies involving 306 patients with ovarian cancer were included. Compared to patients with positive ERCC1 expression, those with negative ERCC1 expression had a better response to platinum-based chemotherapy. The pooled OR was 5.264 (95% CI: 2.928-9.464, P < 0.001) and publication bias was not found (P = 0.904). The result was similar in both in Asians and Caucasians (P < 0.001 and P = 0.028, respectively). ERCC1 protein expression status is significantly associated with response to platinum-based chemotherapy in ovarian cancers.

The purposes of this study were to understand the influence of perceived service quality in upscale Korean restaurants on a customer's feeling response and revisit intent, and to empirically analyze whether a customer's feeling response plays a mediating role between the service quality and revisit intent. Based on a total 303 samples obtained from the empirical research, this study reviewed the reliability and fitness of the research model and verified a total of 2 hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model(SEM). The proposed model provided an adequate fit to the data, ${\chi^2}_{(df=263)}=557.397$, CMIN/df 2.119, RMR .09, GFI .88, AGFI .86, NFI .94, CFI .97, RMSEA .06. The major results of this study can be outlined as follows: Price & value($\beta=.40$), food quality($\beta=.26$) and atmosphere($\beta=.15$) had a significant positive effect on the customer's feeling response, and the customer's feeling response($\beta=.65$) had a significant positive effect on revisit intent. In addition, the effect of the perceived service quality in upscale Korean restaurants on revisit intent was found to be partially mediated by the customer's feeling response. Limitations and future research directions are also discussed.

In the field of population dynamics and chemical reaction the possibility or the existence of spatially and temporally nonhomogeneous solutions is a very important problem. For last 50 years or so there have been many results on the pattern formation of chemical reaction systems studying reaction systems with or without diffusions to explain instabilities and nonhomogeneous states arising in biological situations. In this paper we study time-dependent properties of a predator-prey system with functional response and give sufficient conditions that guarantee the existence of stable limit cycles.
