  • For effective information sharing, data provenance semantics need to be managed effectively. Based on a scheme to represent data provenance semantics, we propose a model to calculate information sharing costs. Information sharing costs are derived from probabilities of type I and type II errors that occur in organizational information sharing, costs related to these errors, and information sharing distances between organizational units which are determined by information sharing workflows. We apply the model to various types of information sharing workflows including departmental information systems, hierarchical information systems, a hub and a stand-alone system. The calculated information sharing costs show that the hub with data standardization is best in information sharing; however without standardization its information sharing cost deteriorates to that of a departmental information system. And, any information sharing workflow is better than a stand-alone system. It is proved that the model is useful in analyzing effectiveness of information sharing workflows and their characteristics.

  • Objective : Diabetic gastroparesis is a complication that is defined as delayed gastric emptying and upper gastrointestinal symptoms and often occurs in long-standing diabetic patients. Bojungikgi-tang (BJT) is a traditional oriental herbal formula that has long been used for the treatment of digestive disorders. The purpose of this study was to investigate the effects of BJT on streptozotocin (STZ)-induced diabetic gastroparesis rat model. Methods : Sprague-Dawley (SD) male rats (250-270g) were divided into 13 groups including normal group, STZ-induced diabetic control group, BJT diet (7 various concentrations), and insulin-, glibenclamide-, metformin-treated group were used for the experiments for the comparison. Diabetic gastroparesis was induced by intraperitoneal injection of STZ. The water intake, food intake, body weights and fasting blood glucose levels were measured. After 4 weeks the animals were sacrificed and gastrin, leptin, insulin, hemoglobin A1C (HbA1c), lactate, lactate dehydrogenase (LDH), bilirubin, creatinine, albumin and lipid levels were evaluated. Results : Intraperitoneal injection of BJT for 4 weeks resulted in increased levels of gastrin in blood and decreased leptin and lactate concentration in STZ-induced diabetic gastroparesis rat model. BJT did not affect insulin, fasting glucose, HbA1c, and lipid levels in STZ-induced diabetic gastroparesis rat model. Conclusion : These results indicated that BJT would have protect effect on diabetic gastroparesis through the improvement effect of gastric motility and fatigue syndrome in STZ-induced diabetic rats. This study shows that BJT might be effective for treatment of diabetes and its complications such as gastroparesis.

  • Objectives : In present study, we investigated a therapeutic effect and optimum dose of Socheongryong-Tang (SCT) on LPS-induced lung inflammation rats model. Methods : Male Sprague-Dawley rats ($260{\pm}10g$) were divided into 12 groups : Group 1 included the normal rats, and Group 2-12 were administrated LPS by intranasal injection to induce experimental lung inflammation. After 1 day of LPS administration, Group 3-9 were treated with SCT ${\times}1/4$, ${\times}1/2$, ${\times}1$, ${\times}3$, ${\times}6$, ${\times}12$ or ${\times}18$, respectively. Group 10-12 (positive control) were treated with dexamethasone 1 mg/kg or acetylcystein 1.5 mg/kg or diclofenac sodium 0.4 mg/kg, respectively. After sacrifice, bronchoalveolar lavage fluid (BALF) was isolated. The levels of IL-$1{\beta}$, TNF-${\alpha}$, mucin glycoprotein 5AC (MUG5AC) were measured in BALF using enzyme-linked immunosorbent assay (ELISA). Results : LPS injected rats exhibited outstanding lung inflammation manifestations, including increased amount of total cells and neutrophil, and upregulated inflammatory cytokines level in BALF. However, the administration of SCT ${\times}1/4$, ${\times}1/2$ and ${\times}1$ decreased total cells and neutrophil, and suppressed the production of inflammatory cytokines, including $IL-1{\beta}$ and TNF-${\alpha}$, and MUG5AC in BALF. Notably, inhibitory effect of SCT ${\times}1/2$ and ${\times}1$ on the level of TNF-${\alpha}$ was markedly better than that of positive controls, dexamethasone and acetylcystein. Conclusions : Taken together, these results suggest that SCT ${\times}1/2$ and ${\times}1$ has therapeutic effects on LPS-induced lung inflammation rats model.

  • This paper presents an application of time series analysis in hourly wind speed simulation and forecast in Jeju Island, Korea. Autoregressive - moving average (ARMA) model, which is well in description of random data characteristics, is used to analyze historical wind speed data (from year of 2010 to 2012). The ARMA model requires stationary variables of data is satisfied by power law transformation and standardization. In this study, the autocorrelation analysis, Bayesian information criterion and general least squares algorithm is implemented to identify and estimate parameters of wind speed model. The ARMA (2,1) models, fitted to the wind speed data, simulate reference year and forecast hourly wind speed in Jeju Island.

  • The objective of this study is to test Parasurman, Zeithaml & Berry(1985)'s service quality gap analysis model, and to confirm reliability and to confirm reliability and validity of the model. The reliability of the model is adopted, but the validity must be retested in the further study. In the results of the gap analysis model, the correlation between consumer expectations and management perceptions of consumer expectations(gap1) was not accepted. The correlation between management perceptions of consumer expectations and service quality specifications(gap2), the correlation between service quality specifications and the service actually delivered(gap3), and the correlation between services delivered and services promised to consumers(gap4) were accepted. To improve domestic telecommunication service quality, practical guides such as standardization of job roles, cooperation among customer-contact persons, communication between managers and employees, evaluation programs for employee's improvement of service quality, appropriate supports for customer-contact persons were suggested. For generalizing the gap model, additional studies under the different contexts and industries will be needed.

  • This study does present things to suggest to foreign multinational corporation or domestic corporation through the empirical study on the standardization level. If we summary this study, it is as follows. In chapter I, we did institute the problems and explain the objects and methods and system of the study. In chapter II, we did explain the universality of the culture and international advertisement. Next, we did explain the background of doing specialization strategy and standardization strategy. Also we did study the previous study about the arguements for and against these. Lsat we did institute the hypothesises as follows. - Hypothesis 1 $H_0$ : The use of westerner appeal means has been increased than 11 years before and is able to increase continuously. - Hypothesis 2 $H_0$ : The use of westerner model and knowned has been increased than 11 years before and is able to increase continuously. - Hypothesis 3 $H_0$ : The use of the English language has been increased than 11 years before and is able to increase continuously. - Hypothesis 4 $H_0$ : The use of the west short piece and background has been increased than 11 years before and is able to increase continuously. In chapter III, we did refer to the method of this study. First, we did adjust the measure of standardization index, and we did work coding it, such after the two coder did check the freguency of the appeal meanstype about the advertisement of four daily report. Then we did select eight production as high involvement production and seven production as low involvement. We did test the coder's trust degree on the such sample to be selected through the 't-test' of the SAS statistic program and regression analysis through the spss/$pc^+$ statistic program to approve the this study's hypothesises. In chapter IV, we did analysis the results of the empirical study on the high or low involvement productions. First, the results of t-test to approve the coder's trust degree is that it is same statistically attentionly the distribution of the sample between coder at 10% attention level. Next, the results of the regression analysis on eight hypothesises are as fellows. In case of high involvement production we are able to speak that the use of the English language appeal among the eight appeals is only standardized. And incase of low involvement production, we are able to speak that the use of the hard-sell appeal among the eight appeds is only standardized. Therefore we did conclude that the standardization level of Korea newspaper advertisement is low. Also this suggests that it will do plan and do the specialzation strategy or localization strategy foreign multinational corporation or domestic corporation in Korea newspaper advertisement. In chapter V, we do present the boundary of this study and new study methods.
