Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

The purpose of this research is to design the moon-shape plate to teach "The Earth and the Moon" in the second semester of the third grade and to find its effectiveness for students to lay their conceptual foundation on the subject. The effectiveness of the moon-shape plate was investigated through an integrated science class in which students learned the shapes and positions of the moon using the device. The integrated science class was held at S elementary school in Busan. 4 classes of the 3rd grade were chosen and divided into two groups, which were a comparative group and an experimental groups., To find out the effects of the adaption classes, pre-tests and post-tests were executed on the concept of the changes of lunar shape and the position of the moon. The cognition for the practical use of the moon-shape plate in the experimental groups was summarized. The results are as follows. First, the moon-shape plate is easy to access and manipulate in 'The Earth and the Moon' class for the third grade students. It is very useful and practical as a learning instrument which is adjusted by the scientific theory. Second, the changes of the rising point of the moon by the lunar calendar are exactly and clearly understood. Third, with the comparison results on the moon position by daily observation and the moon-shape plate, the students can easily draw the right positions and shapes of the moon. Fourth, regardless of the weather condition, the moon-shape plate is very helpful to the learners-centered method. The experimental groups have more effective aspects by showing the meaningful results compared with the comparative ones learned with traditional ways.

The purposes of this study were to investigate the physicochemical characteristics and storage stabilities of various sauces with added Yuza(Citrus Junos). Yuza consisted of three parts: peeled (46.17%), fleshed (43.74%) and seeded (10.09%). Yuza juice revealed 11.33% extraction yield, pH 2.85, 4.18% total acidity, 11° Brix, 1.16% transmittance and 2.63° Brix/acid ratio. Five kinds of sauces with added Yuza juice were Yuza red pepper paste sauce, Yuza soybean sauce for meat, Shahu shabu Yuza sauce, Korean Yuza vegetable sauce and Japanese Yuza soybean sauce. These sauces showed slight changes in pH, total acidity, total bacterial counts and overall sensory characteristics during storage period (60 days). In conclusion, Yuza juice could be applied to various sauces, which remained usable for 60 days.

In this study, an effective methodology to introduce knowledge management system into the retail business is suggested by overall analysis of examples those were carried out in business area. Different from existing studies, which focus on theoretical aspect only, this study focuses its attention on theoretical & practical aspect simultaneously and tries to find a long-term & integrated knowledge management strategy. With examining the examples of knowledge management, this study deals with the fundamental conception, the procedure and the organization of knowledge management. Moreover, this study practically analyzes the knowledge management system of the company named "H", one of the retail business companies. By clarifying the problems, which is involved in the knowledge management process of the above company, this study suggests an improvement methodology to introduce and settle down knowledge management system into retail business company for the future. This study has good results in the viewpoint that it gives a definite direction of knowledge management introduction. However, there is some limitation such as the insufficiency of examples and the omission of documented analysis. Therefore, this study leaves some task to be achieved in the future.

Recent advances in both the diagnosis and treatment of hepatocellular carcinoma have improved the prognosis and changed the clinical significance of the recently increasing distant metastases. Distant metastases found after successful treament of the primary lesions are of great clinical significance for the treatment of hepatocellular carcinoma. The duodenum is a rare site of hematogenous metastases or direct invasion from hepatocellular carcinoma. A 23 year old man was admitted with upper gastrointestinal bleeding. He had been diagnosed with hepatocellular carcinoma and treated by a left lobectomy and chemoembolization. The patient was admittted for 12 months after the treatment of the primary tumor. Endoscopic examination revealed a mass in the duodenal bulb that protruded into the lumen. He died due to massive hematemesis. We report on a rare case of hepatocellular carcinoma with duodenal invasion in a 23-year-old male patient.

Purpose: The purpose of this study was to investigate the extent of empowerment, task performance and job satisfaction perceived by hospital nurses and the relationship among those variables. Methods: The sample consisted of 261 nurses from a university affiliated hospital. Data were collected with self-administrated questionnaires including empowerment, performance and job satisfaction and analyzed using mean, standard deviation, ANOVA and Scheffe' test. Results: The mean scores of variables were as follows. Empowerment was 4.6472, task performance was 3.7814, and job satisfaction was 3.1240. The older, more educated and more experienced nurses showed more empowered and higher job performed than the younger, less educated and less experienced nurses. Empowerment had a positive correlation with task performance and job satisfaction. Conclusions: The results imply that hospital should develop the empowerment program for nurses to be more job performed and satisfied.

This paper is results of experimental research on the effect of application of similarity related to permeability of soil on the consolidation behavior as centrifuge modeling of consolidation is performed with the centrifuge model facility. In this research, the permeability of soil was controlled by changing the viscosity of porewater as the mixed water with glycerin was used during the centrifuge model experiments. The effect of drainage path on consolidation was investigated by installing the vertical drains. A serise of centrifuge model tests with conditions of single vertical and radial horizontal drainage were carried out. Kaolinite and Jumunjin standard sand were used as soft clay and surcharges respectively during tests. For testing condition of single vertical drainage considering similarity of permeability, it was found that consolidation with mixed porewater with glycerin was delayed in comparisons with test results with water only. For conditions of horizontal drainage with vertical drains, a low permeability by changing the viscosity of pore water resulted in delayed degree of consolidation at an initial stage of consolidation. But, it predicted not much differences in settlement as long as the consolidation time was sufficiently long enough to finish consolidation. Consequently, it was found that similarity in permeability should be considered to be critical for the case of centrifuge model experiments related to consolidation with long drainage path.
