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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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 erosion behavior of artificially aged HK40 steel was invested. Erosion tests were conducted at room temperature, 200℃ and 400℃ using Al_2O_3 particles. Erosion rates increased with the increment of temperature. The maximum erosion rate appeared with the impingement angle of 30 degree. The erosion rate increased, reached the maximum at 1000 hours, and after that, decreased with the heat treatment time. The mechanism of erosion seems to be the cutting wear which is very much associated with the strength of material. As results, the erosion rates were rather affected by the tensile strength and the strain hardening coefficient than the hardness and the yield strength. Such changes of material properties would be caused by the change of micro-structure due to the precipitation of carbide and the dissolution of solid element within matrix during the heat treatment.

김용호,--,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2003 Journal of biomedical laboratory sciences Vol.9 No.3

This study was conducted to investigate the influence of chlorella diet supplementation. Blood accumulation and urine excretion levels were measured after the Sprague-Dawley (SD) rats were fed on a chlorella diet supplementation mixed with 40 ppm of CdCl₂. Four groups tested for blood accumulation and urine excretion levels. All four groups fed on a basic diet with a cadmium mixture. The diet for the first group contained only basic diet and the cadmium added to the drinking water. The diet for the three other groups contained cadmium to the drinking water, and 1%, 5% and 10% of chlorella added to the basic diet. A concentration of cadmium for the first group showed a 3.2±0.4 ㎍/l blood accumulatior. level and 41.5±32.9 ㎍/l urinary excretion level, and the second group, which was fed on the basic diet with 1% of chlorella added and cadmium to the drinking water showed a 1.5±0.6 ㎍/l blood level and only 14.1±1.6 ㎍/l urinary excretion level. The other two groups, which were fed on 5% and 10% of chlorella concentration and cadmium to the drinking water did not exhibit any notable effects greater than the group fed on 1% concentration of chlorella. The results suggest that the blood accumulation and urinary excretion of Cadmium are influenced by the chlorella diet supplementation from the concentration of 1% of the basic diet.

조선왕조실록에 나타난 한양의 비보풍수에 관한 연구

김현욱,김두규,김용기 한국정원학회 2002 한국전통조경학회지 Vol.20 No.3

Fengshui is based on the presupposition of the human pursuit of a good site for buildings, including houses, villages, cities and graves. During the Koryo Dynasty(918-1392) and Chosun Dynasty(1392-1910), a major task of Korean traditional scholars, who studied geomancy, was to "read" geographical features and configuration. It aimed to seek for a site to decide on what is good and what is not. Under the circumstances in which they have no other alternative concerning the dwelling area of their life, they have been forced to do their best to turn a worse residential area into a better one. They, thereby, have invented and promoted an idea concening Complementary Setup Fengshui(裨補風水). The Complementary Setup Fengshui had been forged in view of a national project during the Koryo Dynasty and Chosun Cynasty. Consequently, we have called it ’National Landscape Architecture’. The purpose of this paper is to take an analytic look at the history and basic principles (of the Complementary Setup Fengshui), based on he historical record of the Chosun Dynasty with a view to finding the traces of Complementary Setup Fengshui. Only two traces of the Complementary Setup Fengshui are examined in this paper. One is the protection of landscape, the other is to clean the water. And the positive technics of the Complementary Setup Fengshui are to plant, to dredge the stream and to make artificial hills. The nagative technics are to prohibit the use and close up a road

瑞石地園의 造營背景과 空間構成에 關한 硏究

김동훈,김용기,김두규 한국전통조경학회 2003 한국전통조경학회지 Vol.21 No.4

This study was carried out to recognize Seokmun Jung Young Bang's (石門 鄭榮邦) thought of planning that appears on planning background and poetry and to examine attributed significance and the aspect projected into the space by analyzing physical distinctive qualities of space interior along with location in Seoseokjiwon(瑞石池園) that is one of representative Boulseojungwon (別墅庭苑) in Choson Dynasty period. This study is designed to grasp life of Jung Young Bang(鄭榮邦) as a builder of Seoseokjiwon, planning background, distinctive qualities of surrounding environment and location. Also it examined how Jung Young Bang's planning thought is expressed into the Seoseokjiwon interior space by analyzing space composition with symbolic meaning. The consequences of the study through the above analysis are as follows; 1. Jung Young Bang displayed his thought and philosophy by naming space components when he built Seoseokjiwon and filled in his poetry. The symbolic meanings in Kyeongjeongjapyeong(敬亭雜詠) are coexisted into Confucianism and Taoism. The Confucianism, projected into the space displaying his nature as a Confucian and Taoism in the space is reflecting the unstable society at the time. 2. At present, Seoseokjiwon's space structure is divided into the detached house, living house and entrance. The detached house has been arranged with pond as the center, Kyungjung(敬亭) and Juiljae(主一齊). Also artificial landscape architecture such as tree planting and exposed rock in pond is adopted. Unlike the detached house, almost no trees are planted in the living house for convenient housework. The entrance is a mediator between inside and outside. 3. Jung Yeong Bang's thought in planning, expressed in specific forms into the garden, are found in Gyeongjeongjapyeong that 11 (39%) are in Confucianism and 10 (36%) are in Taoism among 28 space components. The space of buildings and pond surroundings are in secularity space with Confucianism and the inside of pond represents future life space such as Utopia.
