  • The purpose of this study is to identify the combinated factors of leaf mustard kimchi which confer the highest utility on tourists, and to establish the relative factors of importance in terms of tourists' contribution to total utility to their tour purpose. Conjoint model, $X^2$ analysis, Max. Utility model, BTL model, Logit model, K-means cluster analysis, and one-way ANOVA analysis are used for this study. The findings from this study are as follows: First, the Pearson's R and Kendall's tau($\tau$) statistics shows that the model fits the data well to the tourists' visit purpose. Second, when they choose a sightseeing place, tourists' taste for food renowned in the local area is a very important factor. Third, the leaf mustard kimchi some tourists most prefer has light red color and mild taste, and they buy it in a shaped packing, at a cheap price and directly at the kimchi factory. The leaf mustard kimchi the other tourists most prefer has light red color and highly pungent taste, and they buy it in a shaped packing, at a cheap price and directly at the kimchi factory. Fourth, by the results of BTL model and Logit Model analysis, some tourists most prefer an experimental model of leaf mustard kimchi which has light red color and mild taste. They want to buy it in a shaped packing, at a cheap price and directly at the kimchi factory. The other tourists most prefer an experimental model of leaf mustard kimchi which has light red color and highly pungent taste. They want to buy it in a shaped packing, at a cheap price and directly in the kimchi factory. Finally, the writer hopes this study will provide the kimchi marketers with some insights into the types of popular leaf mustard kimchi designs that could be successfully developed.

The luxury fashion brands with strong brand power permeates through various regions of the world with high added value and buying power. This study was conducted to determine the dimensions of the luxury fashion brand equity so that the fashion marketers can develop strategies to increase their brand power. ID find out the dimensions of the luxury fashion brand equity, qualitative as well as quantitative research methods were employed. Qualitative research was conducted by interviewing 12 consumers who were loyal to the luxury fashion brands. A total of ten dimensions(uniqueness, sophistication, display, economical and utility value, overall pleasure, satisfaction, reputation, trust respect, social acceptance) were identified as a result of the literature review and the qualitative analysis, and a questionnaire was developed based on them. The questionnaire was administered to 250 subjects and the responses were analyzed by factor analysis to confirm the dimensions empirically. As a result of factor analysis, 7 dimensions of fashion luxury brand equity are 'chic and pleasure', 'trust', 'distinction', 'reputation', 'economical and utility value', 'social acceptance', and 'status'. First, 'reputation', 'economical and utility value' and 'social acceptance' are similar to the result of the literature review and the qualitative analysis. Next, 'Chic and pleasure' included 'overall pleasure','display'and'sophistication'that were identified previously. We knew that People would expect emotional responses such as display through luxury fashion brand. 'Trust' included 'trust' and 'satisfaction' that were identifed previously. 'Distinction' included 'uniqueness' and 'respect' that were identifed previously. Finally, 'status' included 'sophistication' and 'reputation' It seemed that the concept of 'sophistication' was near symbolic rather than descriptive.

  • Background: Radial probe endobronchial ultrasound (R-EBUS) is widely used for diagnosing peripheral pulmonary lesions. However, the utility of R-EBUS-guided transbronchial lung biopsy (TBLB) for diffuse lung lesions (DLLs) remains unknown. We designed this study to evaluate the utility of R-EBUS-guided TBLB in DLLs. Methods: This retrospective study enrolled patients admitted from January 2016 to November 2017 who underwent TBLB for DLLs. The R-EBUS-guided TBLB and blind TBLB groups were compared. DLL was defined as any lung disorder that involved more than one segment of the lung. In both the groups, fluoroscopy and guided sheath were not used during TBLB. Results: A total of 127 patients underwent TBLB for DLLs (67 patients in the R-EBUS-guided TBLB group and 60 in the blind TBLB group). There were no differences in age, sex, and comorbid illnesses between the two groups. Furthermore, there was no difference in the TBLB diagnostic yield of the two groups (p=0.660) although more samples were collected from the R-EBUS-guided TBLB group (p=0.003). Procedure time was significantly longer in the R-EBUS-guided TBLB group than in the blind TBLB group (p<0.001). Thus, incidence of pneumothorax was significantly lower in the R-EBUS-guided TBLB group than in the blind TBLB group (p=0.032). Conclusion: Diagnostic yield in DLLs did not differ between the R-EBUS-guided TBLB and blind TBLB groups. Findings show that R-EBUS-guided TBLB in DLLs may reduce risk of pneumothorax.

  • Conjoint analysis estimates how much each of the attributes is valued on the basis of the choices consumers make among product concepts that are varied in systematic ways. The purposes of this research were to evaluate the relative importance of each fabric constituent characteristic for the consumer's utility or preference, to compare with the relative importance between the trained and the untrained panelists, and to identify the combinations of the constituent characteristic of knit fabric which offer consumers greater utility. Conjoint analysis was conducted using data taken from 54 trained and 54 untrained panelists, who rated preference for 12 different knit fabrics. The stitch length had a greater effect on knit fabric preference than the mixture ratio of fiber. There was no difference on effect of knit constituent characteristics for preference between the trained and the untrained panelists. Total, trained and untrained group preferred a knit fabric that had a higher acrylic mixture ratio and a short stitch length.

  • We have examined the utility of alkaline ionic water for processing water In order to compare with piped tap water in cooking rice, making kimchi, making bean curd, raising bean sprouts and parboiling spinach. And we have estimated the quality of them. The result of the examination was as follow. A rice cooked with alkaline ionic water had pale yellow color, and had good quality in polish, viscocity, taste, odour and retrogradation as compared with a rice cooked of piped tap water. In the case of a water kimchi, refreshing taste and other kinds of taste were good. Unpleasant taste and smell have decreased. Fresh colour of a Chinese cabbage were maintained long because of the prevention of destruction of chlorophyll. In the case of bean sprouts, sprouting rate was promoted up to 2∼3% during the period of 2∼3 days as compared with that treated with piped tap water And the growth state was good and the contents of vitamin C were high as compared with those with piped tap water. In the case of parboiling of green spinach, the alkaline ionic water helped keeping the chlorophyll of spinach. In the case of bean curd, soft taste, polish, smell and total taste were good. The Utility value of alkaline ionic water for the processing of soft bean curd was recognized by making it soften.

  • This study was conducted to analyze the cost-utility of ramosetron monotherapy, trimebutine monotherapy and trimebutine+loperamide combination therapy in male diarrhea-predominant patients with irritable bowel syndrome (IBS) in Korean healthcare setting. We constructed a decision-analytical model to estimate both total costs for each state of health and outcomes such as IBS-symptoms improvement for 3 and 6 months time horizon. Base analysis found that for ramosetron treatment with the price of KW910 for 5 ${\mu}g$ tablet, incremental cost effectiveness ratios (ICERs, cost per quality-adjusted life day) were KW85,000 and KW62,000 for 3 months and 6 months, respectively, compared with trimebutine. But ramosetron was a dominant strategy when compared with trimebutine+loperamide for both 3 months and 6 months. Sensitivity analyses showed robust results for drug acquisition costs till ramosetron price of KW950/tablet. In conclusion, ramosetron was a cost-effective regimen compared with trimebutine or trimebutine+loperamide from the societal perspective.

  • The purpose of this study was to investigate the utility of the Luria-Nebraska Battery-Children's Revision (LNNB-CR) in the clinical situation in Korea: LNNB-CR was applied clinically in order to examine how well it differentiates brain damaged children from normals. Subjects were 30 children with the average age of 10 years. Among them 15 were diagnosed as the 'brain damaged' group, and the remaining 15 were normal. All subjects of the two groups were tested on all items in accordance with LNNB-CR manual. Data were analyzed by percentage, correlation coefficient, and t-test. The results were (1) the degree of consistency between testers averaged 97.2% which confirmed the stability of the scoring system. (2) Split-half reliability was ranged from .75 on the Tactile Scale (C3) to .95 on the Memory Scale (C10). Thus, consistency of items within the scales appeared high. (3) Internal consistency reliability ranged from .74 on the Visual Scale (C4) to .98 on the Reading Scale (C9). Thus, the homogenity of items within the scales appeared high. (4) In the diagnostic discriminative power test between the two groups, both individual scales and total scores showed significant differences at the level of p<.001. (5) The discriminative power test between two groups on all items showed significant differences at the level of p<.05 or better in 126(85%) out of 149 items. These results are supportive of the diagnostic utility of the application of LNNB-CR to the clinical situation in Korea. However, extensive additional research is needed in order to prove its worth.
