Geumgang canal is planned to connect Geumgang lake with Saemangeum reservoir to accelerate desalinization and dillute polluted water in Saemangeum reservoir. The purpose of this study is to evaluate the variations of water quality by divesion of Geumgang lake flow to the Saemangeum reservoir. WASP5 model was used to estimate water quality concentration of Geumgang lake. Model calibration and verification was done for water quality data for 2001 and 2002. As a result of simulating water quality concentration for 4 scenarios, which was considered whether Geumgang canal will be built, there was little influence on water quality in Geumgang lake though Geumgang lake flow diverted to Saemangeum reservoir.

Calculate content validity of the tool by 25 nursing expert panel of judge. 4. Verify reliability and validity of the tool. 5. Finalize an evaluation tool for the quality of the nursing care in musculo-skeletal disorder. The results of this study were as follows : 1) Development an evaluation tool for the quality of nursing care in musculo-skeletal disorder. (1) The evalution tool of this study was developed 5 standards, 33 criterias and 133 indicators. (2) 5 standards were divided according to Nursing Process. from standard 1 to standard 5, involved criterias were each 6(18%), 3(9%), 3(9%), 15(46%), 6(18%). 2) Verify reliability and validity of the tool. (1) Score of adequate degree for content validity of 33 criterias and 133 indicators were every average 2.82. (2) Inter-rater reliabilities(consentaneity score) of the tool by pearson correlation coefficient between three raters were : r=.7506, r=.8934, r=.6695. and Inter-rater reliabilities by single-facet crossed design were : r=.7464. (3) The alpha coefficient relating to internal consistency was .8524 over all 30 items of 33 criterias of developed tool. (4) Score of the quality of nursing care following to generaal characteristics of this study subjects were stastically significant differences according to educational level (F=2.93, p=.029)and diagnosing classification (F=2.50, p=.042). Through this study, I'm sure that the developed tool for the quality of patient care in musculo-skeletal disorder will show the way of more improvement of the quality of nursing care and effective nursing interventions.

Purpose - The Korean child welfare services may have different feelings between providers and users. Few studies on the child welfare service quality have been conducted and research on the coorientation model of child welfare services are nonexistent. We compared the perceptions of Korean child welfare service providers and users in this study. It will have many applications in the service quality fields by applying a coorientation model. Research design, data, and methodology - In order to enhance user satisfaction with child welfare services, around 200 samples were carried out both in Busan and Kyungsangnamdo randomly. Seven point Likert scale was used in the questionnaire. Two measurements were made to evaluate the different positions on the part of child welfare service providers and users to assess their mutual orientation. Paired t-test verification was conducted for congruency analysis, and the verification of agreement and accuracy was analyzed by independent t-tests. Results - We empirically examined the differences between the providers and the users stance. The results are as follows. We have verified the statistical significance of the difference in perception between providers and users. We also confirmed a degree of agreement, a degree of congruency, a degree of accuracy and a degree of meta agreement in the study. In the Korean child welfare service quality, the coorientation model of process quality appeared in the form of semi-dissensus, the coorientation model of results quality were shown in the form of ignorances and the coorientation model of physical environment quality were investigated in the form of semi-dissensus. Conclusion - The study concluded that users need to understand more about the providers in order to enhance the coorientation model in process quality and physical environmental quality, and the providers need to persuade the users clearly about the positive factors. To enhance the coorientation model of the result quality, it can be misunderstood by guessing that the other party will positively evaluate it. Therefore, users believe that they need to talk more clearly to the provider about the results of the korean child welfare service quality to reduce misunderstandings and to understand each other about the resulting quality.

The characteristics of water quality variation were predicted by stochastic model in Chungju dam, north Chungcheong province of south Korea, Monthly time series data of water quality from 1989 to 2001;temperature, BOD, COD and SS, were obtained from environmental yearbook and internet homepage of ministry of environment. Development of model was carried out with Box-Jenkins method, which includes model identification, estimation and diagnostic checking. ACF and PACF were used to model identification. AIC and BIC were used to model estimation. Seosonal multiplicative ARIMA(1, 0, 1)(1, 1, 0)$_{12}$ model was appropriate to explain stochastic characteristics of temperature. BOD model was ARMa(2, 2, 1), COD was seasonal multiplicative ARIMA(2. 0. 1)(1. 0, 1)$_{12}$, and SS was ARIMA(1, 0, 2) respectively. The simulated water quality data showed a good fitness to the observed data, as a result of model verification.ion.

This study focuses on hotel kiosks that have begun to be introduced in earnest in mid-priced hotels, and the quality attributes of hotel kiosks, which are expected to be introduced throughout the hotel industry in the future, and validates them using a revised IPA(Importance-Performance Analysis). An online survey was conducted targeting hotel users who had used hotel kiosk devices, and difference analysis and IPA analysis were conducted on 239 people, excluding 61 who responded insincerely. As a result of the verification, there was no significant difference in hotel kiosk quality attributes by age, but there was no significant difference by age. It was found that there was a significant difference. As a result of analyzing the difference between importance and satisfaction, it was found that there was a partially significant difference. These results suggest standards for quality attributes in hotel kiosks and provide academic implications for future research and practical implications for hotel management practitioners.
