We evaluated the sensory characteristics of Gangjung base obtained from various manufacturers, using a sensory descriptive analysis. Significant differences were observed for all sensory attributes of Gangjung samples with the exception of 'toothpacking'. Sample A showed high intensities for 'external color', 'external roughness', 'sweetness', 'toasted soybean powder flavor', 'crispness', 'fracturability', 'oiliness', and 'loose particles,' whereas it had low intensities for 'rice flour flavor', 'hardness', and 'toughness' compared to those of other samples. Sample B had more 'sourness', 'butyric acid flavor', 'fermented rice flavor', and 'degree of melting' but lower 'air cell size', 'fracturability', and 'flake roughness'. Sample C showed high intensities for 'expansion', 'hardness', 'crispness', and 'flake roughness', whereas sample D showed low intensities for 'expansion' and 'sourness'. These results indicate that Gangjung base samples are markedly different depending on the manufacturer.

In this paper, the computational problems of packet transmission probability (PTP) in a computer communication network (CCN) under flooding routing are investigated. To avoid a congestion under this routing, two control methods are considerd, i. e., copy storage control and hop count control. Problems of PTP under flooding routings with these two control methods are respectively shown to be equivalent to those of source-to-terminal reliability(STR) with an exception for a case of hop count control where the hop count is less than the length of the longest path. For this exceptional case, an efficient computational algorithm for PTP is developed. This algorithm is proposed as an efficient tool for the determination of hop count which satisfies a given reliability constraint. A numerical example illustrates a proposed algorithm.

The purpose of this paper is to investigate the relationships among transformatonal leadership, gropefficacy, and group performance. A total of 321 empolyees of a fire and marine insurance frim in Seoul anonymously completed the Multifactor Leadership Questionnaire-Form V, which consists of three factors(charisma, individualized consideration and intellectual stimulation) for transformational leadership, and two factors(contingent reward and management by exception) for transactional leadership. The sample, which largely consists of sales supervisors and salesmen, includes 41 sales office branches. The findings of the study are as follows. Transformational leadership is closely associated with group-efficacy and group performance. That is, there are significant correlations between transformational factors and group-efficacy, between the factors and group performance, and between group-efficacy and group performance. A stepwise multiple regressio analysis revealed that transformational leadership augmented the subordinates's extra efforts. It was also found that group-efficacy was mediating the relationship between transformational leadership and group performance. The managerial implications of these findings and future directions of research are also discussed.

Food quality in food processing and storage were affected by the kinds of phenolics involved. To analyze phenolics of Chebulae Fructus by the way of GC-MSm methylation and trimethylsilyation(TMS) are necessary. The methods of methylation were dimethyl sulfate method and diazomethane method. so this study was undertaken to research the better methylation method before measuring GC-MS. But dimethyl sulfate method of methylation was not sufficient to analyze phenolics. So the phenolics of Chebulae Fructus were analyzed by the diazomethane methylation method and TMS with the pyridine, N-O-bis-trimethylsilyl-acetamide(BSTFA) and trimethylchlorosilane(TMCS). With the exception of pyrogallol and phloroglucinol in insoluble phenolics of Chebulae Fructus, the greater part of phenolics. analysis could be analyzed by GC-MS in company with diazomethane methylation method and TMS.

Uncertainty and dynamism surrounding pervasive systems require new and sophisticated approaches to defining, detecting, and handling complex exceptions. This is because the possible erroneous conditions in pervasive systems are more complicated than conditions found in traditional applications. We devised a novel exception description and detection mechanism based on "situation"- a novel extension of context, which allows programmers to devise their own handling routines targeting sophisticated exceptions. This paper introduces the syntax of a language support that empowers the expressiveness of exceptions and their handlers, and suggests an implementation algorithm with a straw man analysis of overhead.

Purpose: The Purpose of this study was to identify the relationship between leadership styles and empowerment of nursing students. Method: The subjects were 386 nursing students who were in college and university. The data were collected from July 26 to September 18, 2004 by the structured questionnaires. For data analysis, descriptive statistics, Pearson correlation coefficient, t-tets and ANOVA with SAS package were used. Results: Transformational leadership showed a significant difference according to school career, present grade, interpersonal relations, admission motive, satisfaction degree for nursing, satisfaction degree for practice, meaning on nursing job and transactional leadership showed a significant difference according to last session study score, satisfaction degree for nursing. Empowerment showed a significant difference according to school career, present grade, interpersonal relations, satisfaction degree for nursing, satisfaction degree for practice, meaning on nursing job. Charisma, intellectual stimulation, individual consideration and contingent reward perceived by nursing students were positively related to empowerment. Management by exception perceived by nursing students was negatively related to empowerment. Conclusion: The result of this study may be helpful in empowerment improvement of nursing students.

The purpose of this study was to compare shopping orientations and purchase criteria according to the occupational status; professionals, non-professionals, and homemakers among female consumers. Subjects were selected from mailing lists through a random sampling technique in the United States. Collection of the research data was made using an adaptation of the Total Design Method for implementing mail surveys. ANOVA, Regression, and Duncan Test were used to conduct the data analysis on 254 out of 1000 questionnaires. The three job status showed significant differences in 5 shopping orientations(sex role oriented, fashion conscious, credit oriented, catalog oriented, and value oriented). Even after controlling the effect of income and education level, significant differences were noticed in 4 shopping orientations, the exception being value conscious. Brand, price, and country of origin among the job status groups also showed significant differences in results for purchase criteria.

By changing housing market, housing cultural center furnishes information, value added, image of housing. For publicity their unique house, construction companies provide not only concrete and substantial material but also sensible and capacity service through the community space of housing cultural center. The consumer's experience of housing cultural center have an effect on purchase power apartment. The image of enterprise is important to select commodities to consumers. Though main clients are women, housing cultural center has not space concept and aim to concern for them. According to begin women a group of consumers, they have purchasing power in family. Apartment is no exception. Housing cultural center is used as continuous culture space that provide various experiential chance for consumer, especially women by systematize and distinct design detail and feature component. Accordingly, the purpose of this study is an analysis about community space of housing cultural center with the woman marketing based on experience.

In order to characterize the current status and distribution of reptiles currently inhabiting the Republic of Korea, the results of survey data were analyzed in this study. The results of this analysis showed that the reptiles were distributed into two orders, seven families, and 21 species, with the exception of six marine reptiles, including Dermochelys coriacea schlegelii, Chelonia mydas japonica, Caretta caretta, Hydrophis melanocephalus, Hydrophis cyanocinctus, and Pelamis platrrus. Also, the taxonomic revisions of several species were suggested, although this would be ill-advised before further studies can be conducted regarding the current status of marine reptiles in the region.
