Reliable long-term streamflow forecasting is invaluable for water resource planning and management which allocates water supply according to the demand of water users. Forecasting of seasonal inflow to Andong dam is performed and assessed using statistical methods based on hydrometeorological data. Predictors which is used to forecast seasonal inflow to Andong dam are selected from southern oscillation index, sea surface temperature, and 500 hPa geopotential height data in northern hemisphere. Predictors are selected by the following procedure. Primary predictors sets are obtained, and then final predictors are determined from the sets. The primary predictor sets for each season are identified using cross correlation and mutual information. The final predictors are identified using partial cross correlation and partial mutual information. In each season, there are three selected predictors. The values are determined using bootstrapping technique considering a specific significance level for predictor selection. Seasonal inflow forecasting is performed by multiple linear regression analysis using the selected predictors for each season, and the results of forecast using cross validation are assessed. Multiple linear regression analysis is performed using SAS. The results of multiple linear regression analysis are assessed by mean squared error and mean absolute error. And contingency table is established and assessed by Heidke skill score. The assessment reveals that the forecasts by multiple linear regression analysis are better than the reference forecasts.

This study is based on an empirical study on consequences of emotions and emotional labor in the food-service industry. It analyzed the effect of emotional labor on emotions of emotional laborers and the effect of emotional labor on communication skills. Data used for analysis were collected through the questionnaire surveyed on the various samples including employees of family restaurants, Korean restaurants, Chinese restaurants, Japanese restaurants, etc. The result of data analysis indicated that only the efforts for emotional expressions among the factors influenced affirmative emotion(P-value=0.042). It also showed that the factor of the efforts for emotional expressions by researchers had a positive effect on both language communication skills and non-language communication skills(P-value=0.000). This study was valuable in the aspect that emotions and communication skills were first selected as dependent variables of emotional labor and it verified causality between emotional labor and these variables. However, it also has some limitations that its sample size was small and it depended on convenience sampling.

An outcome-based curriculum or competency-based curriculum is regarded to be one of the mainstream curricula to make students centered. It is believed to be able to support a flexible, time-independent curriculum. However, it is not easy for the curriculum developers to convert from the traditional curriculum to an competency-based curriculum. Traditional medicines including Sasang constitutional medicine(SCM) have been on the verge of transforming their curricula. Considering the contents of the clinical skills in terms of an outcome-based curriculum in SCM, at least five categories needs to be covered. First, curriculum developers need to consider the understanding of relevant diseases concerning SCM although SCM could be used as the method to treat all kinds of diseases. Second, curriculum developers facilitate the students to diagnose patients' SCM types. Third, curriculum developers conduct the establishment of competencies to understand the patterns of SCM symptomology. Fourth, curriculum developers develop the diverse treatment methods and procedures to make students participate. Fifth, curriculum developers make students teach and consult their patients in terms of SCM regimen. Development of the clinical skill contents in detail depends on the situation of each colleges. Competency-based medical curriculum in SCM could influence on the management of the curriculum quality.

This article is concerned to investigate the changing nature of the role of the state in relation to industrial policy to foster the IT industry in the Republic of Korea. In doing this, it has started with economic globalization introduced to the Korean political economy since the late 1980s. It has identified in what ways the state responded to the change, and to what extent the role of the state has fundamentally been changed in the context of policy mechanism in the process towards facilitating the IT industry in Korea. In addition, it presented how the state played a role in skill formation in relation to the industrial policy. In consequence, the role of the Korean state in fostering the IT industry has fundamentally changed from that as the developmental state in the industrialization process. In the process, that the strategic co-ordination role of the state and relations between the state and private capitals and societies are very significant to achieve the economic goal is presented as results, as well as some future tensions that would encounter in the way of charting the current policies.

Purpose: This study was to investigate the relationships among patient safety culture, safety competence and safety nursing activity among nurses in anesthetic and recovery rooms, and to identify the factors contributing to safety nursing activity. Methods: A descriptive correlational study was conducted. Participants were 156 nurses from 13 hospitals. Data were collected from February 11 to March 15th, 2019, and analyzed using descriptive statistics, t-test, Mann-Whitney U test, one-way ANOVA, Pearson's correlation and multiple regression analysis with SPSS statistics 24.0 Program. Results: Safety nursing activity was significantly different in relation to nurses' level of education, position at work, clinical career, clinical career at anesthetic and recovery rooms, and work experience in patient safety. Safety nursing activity demonstrated a significant positive correlation with patient safety culture and patient safety competence. Factors contributing to safety nursing activity were patient safety knowledge, skill and attitude, clinical career, clinical career at anesthetic and recovery rooms, and the patient safety improvement system which explained 57.0% of total variance of safety nursing activity. Conclusion: To improve safety nursing activities at anesthetic and recovery rooms, it is necessary to develop patient safety programs with enhanced knowledge, skill and attitude to take patient safety as a top priority.

The purpose of this paper is to compare seafarers' behavior according to traffic conditions of a road and an onshore locations. Behaviors are classified into three categories: Skill-, Rule- and knowledge-based mode. Experimental data were collected using the questionnaires for navigators, working in a merchant ship. To compare the behaviors, we used the four analysis method; the degree of frequency, reliability test, correlation and linear regression. As a result of the study, it was found that Skill-based behavior shows more higher in the road traffic than the maritime traffic, and rule-based behavior shows more higher in the maritime traffic than the road traffic. Also, the behavior in the navigation situation showed statistical significance. Especially, in the case of Rule-based behavior, a high correlation between road and maritime was found. This study can be expected to apply to complementary system utilization between error management system of onshore and maritime traffic.
