Fascioliasis is a parasitic infection caused by liver flukes. Although several cases have been reported in Korea, phylogenetic analysis of isolates is lacking. In this study, a 66-year-old woman with right upper quadrant (RUQ) abdominal pain was diagnosed as fascioliasis involving abdominal muscle by imaging study. She received praziquantel treatment, but symptoms were not improved. Lateral movement of the abscess lesion was followed. Trematode parasite was surgically removed from the patient's rectus abdominis muscle. The fluke was identified as Fasciola hepatica based on sequence analysis of 18S rDNA. To determine the phylogenetic position of this Fasciola strain (named Korean Fasciola 1; KF1), the cox1 gene (273 bp) was analyzed and compared with the genes of 17 F. hepatica strains isolated from cows, sheep, goats, and humans from various countries. Phylogenetic analysis showed that KF1 was closely related with the isolates from China goat.

The importance-performance analysis (IPA) is a widely used analytical technique that produces a priority of managerial attention for the customer satisfaction. This study attempted to compare various different approaches of IPA such as direct and indirect measurement of importance, and traditional four quadrants grid model and diagonal grid model of IPA. Data on 17 inpatient service quality attributes were collected from 234 inpatients of a general hospital. Eight IPA grids were produced to compare the result of each model. Based on the study results the strength and weakness of each model were discussed, and a set of recommendations for practical application of the IPA in hospital settings was suggested.

This study was targeted on the Korean, Chinese, and Japanese parents of preschoolers to investigate the importance and satisfaction of foodservice quality and the importance and performance of foodservice management of the preschool foodservice establishments. The present study conducted a survey on 390 randomly chosen parents of preschoolers (130 Korean, 130 Chinese, and 130 Japanese). Respondents' importance-satisfaction of foodservice quality characteristics and their importance-performance of foodservice management were measured. In order to test for differences between the groups, paired t-test, one way ANOVA, and IPA (Importance-Performance Analysis) were performed. The results were as follows. The importance of foodservice quality was significantly higher than the satisfaction on all items, according to the parents of Korea, China, and Japan. The importance of foodservice quality was higher in Korean parents than in Chinese and Japanese parents. According to ISA results with foodservice quality characteristics, the characteristics with relatively low satisfaction but high importance (II quadrant) was 'Diversity of menu' in both Korean and Chinese parents, and 'Sanitation of tables and chairs' in both Korean and Japanese parents. The importance of foodservice management was significantly higher than performance on all items in Korean, Chinese and Japanese parents. The performance of foodservice management was higher in Chinese than in Japanese and Korean parents. According to IPA results with foodservice management, the management with relatively low performance but high importance (II quadrant) was 'Preparation' in Korean parents, and 'Facility and equipment' in Japanese parents. Therefore, the items with relatively low satisfaction (performance) and high importance should be well-managed.

Most of the respondents(68.3%) had overall working experiences less than 58 months and almost half of them(56.3%) were married. The school foodservice operations which employed a chef were 50.3%. The food suppliers' attributes that were recognized by the dieticians with high value of mean importance scores were: food quality, maintenance of food quality, accuracy in filling orders, quality of delivery facilities, on time delivery and packaging. Average mean score for importance was 4.33('important') out of 5 and mean score for performance was 3.50('so-so') out of 5. By IPA techniques, the attributes that deserve higher attention were those that ranked high in importance and low in performance(Quadrant A). The coordinates in Quadrant A were geographical location of supplier, maintenance of food quality, provision of information on cost variation and salesman's knowledge.
