Purpose - This study attempts to examine the impacts of consumers' perceived service convenience of retailers on various service performance metrics such as service quality and customer satisfaction. It also tries to investigate differences in the importance of service convenience dimensions on service performance between a department store and a general super market. Research design, data, and methodology - The four hypotheses in this study were proposed and tested. Two hypotheses were on the causal relationships between service convenience dimensions and service performances (service quality and customer satisfaction). The other two hypotheses were on comparisons for the effects of convenience dimensions on service quality and customer satisfaction between department stores and general super markets. To test the hypotheses, three department store chains (Hyundai, Lotte, and Shinsegae department Store) and three general super markets (E-mart, Homeplus, and Lotte mart) were involved. Overall, 510 usable responses were used. The data were analyzed using regression analysis. Results - The results largely support the hypothesized relationships of the proposed model. The results show that access convenience, transaction convenience, benefit convenience, and post-benefit convenience have positive influences on service quality, whereas decision convenience, access convenience, transaction convenience, benefit convenience, and post-benefit convenience have positive effects on customer satisfaction. Furthermore, the results show that there are differences between department stores and general super markets in the effects of benefit convenience and post-benefit convenience on service quality as well as the effects of transaction convenience and post-benefit convenience on customer satisfaction. Conclusions - The concept of service convenience is important in retail environments but little is known about this topic in retail literature. Specially, while service convenience dimensions have different impacts on service performance in distinct retail environments, there has been little investigation or comparison between retail types as regards service convenience. This study is the first to test the differences between distinct retail types (department stores and general super markets) on the service convenience-service performance links. Managerially, the findings of this study suggest that the service convenience management of retailers is an important part of successful service performance management. Because it is most important that both department stores and general super markets enhance benefit convenience to improve service performance, managers of both store types need to invest their resources to reduce consumers' perceived time and effort expenditures to experience the retailer's core benefits. Therefore, the results of this study suggest that retail stores should spend human and financial resources to enhance customer perceptions of service convenience, while also considering what constitutes the service outcome in the consumer's mind. Furthermore, the findings suggest that managers need to use different service convenience management tactics in department stores and general super markets. Specifically, managers in general super markets should pay more attention to benefit convenience and transaction convenience to achieve better service performance whereas managers in department stores should concentrate on post-benefit convenience to create customers' positive evaluation.

Carbohydrate(CHO) counting is a meal planning approach used with diabetic patients that focuses on carbohydrate as the primary nutrient affecting post-prandial glycemic response. However, it has not been used in meal management of diabetic patients in Korea. CHO counting can be used by clients with type 1 and 2 diabetes. The purpose of the study was to determine the barriers to utilize the CHO counting when three levels of CHO counting were educated to type 2 diabetic patients who started continuous subcutaneous insulin infusion (CSⅡ) therapy by nutrition lectures and counseling. And the CHO-to-insulin ratios were determined for the individual patients who followed the carbohydrate counting as a meal management, and the factors to influence the CHO-to-insulin ratios were selected through the stepwise regression analysis. Twenty- four subjects were received three lectures, and one or two nutritional counseling for a month. The average age of the subjects was 50.7 years, and the duration of diabetes was 9.4 years. Their body mass index (BMI) was 21.5 kg/$m^2$. The difficulties of using CHO counting were 1) confusing the CHO exchange system to diabetic food exchange system, 2) lack of basic nutrition and not distinguishing nutrients such as CHO, fat and calorie, and 3) lack of motivation to make effort to count and record the amount of carbohydrates eaten. Nutritional counseling replenished the nutrition education and made patients practice CHO counting. Average CHO-to-insulin ratios at breakfast, lunch and dinner were 4.1$\pm$3.3, 2.9$\pm$2.6 and 2.9$\pm$3.0units/23g of CHO, respectively. CHO-to-insulin ratios were influenced by gender, age, BMI, post-prandial blood glucose levels and post-prandial c-peptide levels. The effective education and nutritional counseling of CHO counting can make CHO counting applicable to type 2 diabetic patients as meal management for improving glycemic control with less hypoglycemic episode.

Objective: There have been many cases of spontaneous adverse drug reactions to fentanyl at a regional pharmacovigilance center in the hospital. To assess the factors causing the adverse drug reactions reported in patients receiving fentanyl patient-controlled analgesia (PCA) monotherapy or in combination with fentanyl transdermal therapeutic system (TTS) for acute post-operative pain management. Methods: We conducted a retrospective cohort study with all patients prescribed fentanyl PCA for pain management after orthopedic surgery at a single university hospital from June 2012 to May 2013. We analysed the factors causing adverse drug reactions reported by a spontaneous reporting system in patients receiving fentanyl PCA monotherapy and those receiving fentanyl TTS in combination with fentanyl PCA. Results: Based on the spontaneous adverse drug reaction reporting, the risk ratio for the incidence rate of adverse drug reaction in the fentanyl TTS combination therapy group was 3.04 (95 % CI: 2.4-4.00, P < 0.0001), which was approximately 3-fold higher than that reported for fentanyl PCA monotherapy. Only 60 % of the adverse drug reactions were reported. Conclusion: It is inappropriate to add fentanyl TTS to fentanyl PCA to manage post-operative acute pain. There is a need to improve adverse drug reaction reporting. We expect that regular analysis of adverse drug reactions reported at regional pharmacovigilance centre would aid in appropriate drug utilization by patients.

Objective: To compare the analgesic effects and adverse drug reactions (ADRs) of fentanyl intravenous patient-controlled analgesia (ivPCA) with nefopam, a centrally acting analgesic agent with demonstrated opioid sparing activity, as compared to ketorolac in a tertiary teaching hospital. Methods: A retrospective evaluation of electronic medical records was conducted on patient records including either nefopam or ketorolac with opioid ivPCA for post-operative pain management in general surgery department from January to December 2014. The status of pain control and ADRs were collected. Results: Out of 6,330 general surgery cases, nefopam was given in 153 prescriptions (6.9%) and ketorolac in 81 prescriptions (3.6%). The level of pain control was not different between two groups (70.9% vs. 75.3%; p = 0.51), but ADRs were more frequently reported in nefopam group (9.8% vs. 2.5%; p < 0.05). New ADRs of hot flushes (n = 1) and paresthesia in hands (n = 1) were reported in nefopam group and they were unlisted in the approved package insert. No serious ADRs were reported in both groups. Conclusion: Our findings presented that nefopam showed a similar analgesic effect and higher ADR rates compared to ketorolac as an adjuvant to fentanyl iv PCA for post-operative pain management in general surgery patients in South Korea.

Purpose: To evaluate the influence of how the trauma care system is applied on the management of trauma patients. Methods: We divided the patients into a pre-trauma system group and a post-trauma system group according to the time when we began to apply the trauma care system in our institution. We compared the general characteristics, injury severity score, initial response time to the trauma patients, number of preventable deaths, and clinical outcomes between the two groups. Results: The numbers of patients in the pre-trauma system group and the post-trauma system group were 188 and 257, respectively. No differences in the patient's median ages, trauma scores (ISS, RTS, TRISS) and proportions of severe trauma patients (ISS>15) were observed between the two groups. The number and the proportion of patients who were admitted to our hospital were increased in the post-trauma system group. The time interval from trauma CP activation to emergency surgery or angio-embolization, and the patient's time spent in emergency room were shortened in the post-trauma system group. However, the lengths of the ICU stay and the hospital stay, and the number of in-hospital mortalities were not improved in the post-trauma system group. In severe trauma patients (ISS>15), there were no differences between the two groups in the number and the proportion of admitted patients, and the time interval from trauma CP activation to performing a diagnostic and therapeutic procedure was not shortened in the post-trauma system group. Conclusion: Application of the trauma care system has shortened the time between the initial response and patient management. However, this improvement was not enough to result in better clinical outcomes. More trauma physicians, multidisciplinary cooperation, and a well-organized trauma management process will be needed if the maximum efficacy of the trauma system is to be achieved.

The purpose of this study was to examine the relationship among perceived health status, self-esteem, self-efficacy and health promoting behavior, and to determine the predictors of health promoting behavior in post-mastectomy patients. The study, a descriptive correlational study, was done with structural questionnaires. A total of 51 post-mastectomy subjects from C university hospital in Kwang-ju, South Korea completed mail-in self-reporting questionnaires during a three month period from March to June, 1999. The data were collected using Lawstone's(1982) perceived health status scale, Rosenberg's(1965) self-esteem scale, the modified self-efficacy scale(Shere et al, 1982), and the modified health promoting lifestyle profile (Walker et al, 1987). The data obtained were analyzed according to percentage, mean and standard deviation, principal component analysis, varimax rotation, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression. The results were as follows: 1. The health promoting behavior measurement resulted in six factors. Each factor was labelled as follows: self-actualization, nutrition, stress management, exercise, health responsibility and interpersonal support. The total percent of variance explained by the six factors was 58.4%. 2. The mean score of health promoting behavior was 85.92(range 58~117). The scores of six factor were nutrition 3.20, self-actualization 2.59, stress management 2.58, interpersonal support 2.58, health responsibility 2.49, and exercise 2.34 on a four point scale. 3. When the score of health promoting behavior factors were compared by general characteristics. Factor I: self-actualization, differed significantly by the frequency of pregnancy (F=3.06, p=.037). Factor II: nutrition differed significantly by drinking experience(t=-2.26, p=.028) and the pre- or post stage of menopause(F=2.69, p=078). FactorIII: stress management differed significantly depending on regularity of mensturation(t=-2.12, p= .042). FactorIV: exercise differed significantly by type of religion (F=2.49, p=.072), marital status(F=5.03, p=.010), and feeding type (F=2.64, p=.036). Factor V: health responsibility differed significantly by regularity of mensturation(t=2.18, p=.037). 4. The total health promoting behavior score was significantly related to self-esteem and perceived health status(r=.610, p.006; r= .378, p=.006). The score of selfactualization also corresponded with selfesteem and perceived health status(r=.556, p=.001; r=.343, p=.013). 5. The predictor to explain the score of health promoting behavior was self-esteem, which accounted for 37.1% of the total variance. The predictor to explain the score of self-actualization was self-esteem, which accounted for 30.9% of the total variance. The score of nutrition was primarily affected by both premenopause and drinking experience, which accounted for 13.1% and 9.5% respectively. Finally, the score of exercise was dictated by marriage, Buddhism, no experience of breast feeding, which accounted for 17%, 9.8%, & 5.2% respectively. In conclusion, self-esteem is the main predictor for health promoting behavior in post-mastectomy women. These findings suggest a need for nursing strategies which promote self-esteem in such patients.

There have not been the best method for improving the management system of an enterprise. Its management system must be changed according to new environment. Therefore, the food service industry had to accept outsourcing strategies to reduce cost and construct the core-capability of enterprise. In this respect, we studied the introduction and the satisfaction in outsourcing strategies for family restaurants, including a post of enterprise, decision on the supply-enterprises, contract preparation, cost of outsourcing, recontract items and outsourcing result estimation. The results of this study were as follows; First, 90.5% of managers for 7 family restaurants felt that outsourcing is needed. Second, the post of the outsourcing for 7 family restaurants was from 1 to 8; supply for raw food material, cleaning and equipment repair. The introduction of outsourcing for 7 family restaurants started in 1995 and it had constantly made progress up to 2003. Thirdly, the advantages of the outsourcing for 7 family restaurants were increase of benefit, improvement of controllable-power for family restaurants and improvement of employees' satisfaction. Fourthly, 42.9% of managers were satisfied and 4.8% of them were not satisfied. 36 to 40 year old vice-managers were very satisfied with the result of the outsourcing. Fifth, 90.5% of family restaurant managers found the outsourcing to be needed and especially managers in their late thirties realized the outsourcing.
