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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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.

To find out the life style of the obesity boys and girls, I conducted a survey from 922 boys and girls in the middle school students of C city in K province about their ideas about being obese, their home environment, eating habit, exercise style, and how they spend their free time. By analysing the result, I got the following conclusions. 1.Their ideas about being obese and home environment According to the survey 159 of 922 students (17.25%) were catagorized as being obese and when asked whether they think they're obese, the obesity group showed positive responses. The obesity group had high rates of having their parents as being obese, especially their mothers. 2.Eating habit They usually had more than 3 meals a day but the control group ate more frequently than the obesity group, but the obesity group ate faster. When asked, the time they eat meals and the number of times they eat snacks a day, the control group gave higher respose rate than the obesity group. Usually the control group ate more snacks before going to bed than the obesity group and the obesity group prefered to eat meat. 3.Exercise style Both groups were using their houses and playground near by their house to exercise and the control group premiered soccer as their favorite sport compared to the obesity group. 4.Leisure time Their average sleeping hour was 6-7 hours and the control group slept more than 7 hours showing difference with the obesity group.

김동식,정회환,정관수 慶熙大學校 材料科學技術硏究所 1993 材料科學技術硏究論集 Vol.6 No.-

In this paper, we have designed and constructed a scanning tunneling microscope(STM) for studying on the atomic scale strucure of semiconductor surfaces We considered next four points. Firstly, we used triple spring damping system for stable measurement. Secondly, we soldered electronic part on PCB board to minimize electronic noise. Thirdly, we made stable power supply part to reduce drift power noise. Fourthly, stainless steel 302 was used for future UHV experiment. In operating the STM, we could eliminate the effect of external vibration by adopting the triple spring damping system. Noise of 60 Hz which was generated by wire connection between electronic and mechanical part, was eliminated by drying the silver paste thoroughly. Tip voltage was biased by 10mV We have obtained clear images of HOPG(high oriented pyrolitic graphite) when tunneling current was 2nA. In conclusion, we have confirmed that our STM have a resolution of atomic scale by investigation of the image of HOPG surface.

김우승,이관수 한양대학교 공학기술연구소 1993 공학기술논문집 Vol.2 No.1

An alloy solidification problem is considered in a semi-infinite medium for a substance haying an extended temperature range between the solidus and liquidus temperatures. The analysis in the mushy gene has been performed by dividing the zone into two regions since the structures in the mushy gone are different depending upon the region where it is close to the solidus front or liquidus front. The solidus fraction in the mushy zone is assumed to be a linear function of temperature. The temperature distribution in each region is determined and the movements of the solidus and liquidus fronts are obtained as a function of time.

김관수,장인수,박기돈 대전대학교 기초과학연구소 1995 自然科學 Vol.6 No.-

본 연구는 산불 발생시 연소대상 침엽수종인 소나무(Pinus densiflora)와 잣나무 (Plnus koraiensis)의 생엽과 생지를 가열온도에서 시료량에 따른 연소온도 변화와 연소열량의 관계를 조사한 것이다. 잣나무 시료의 함수량은 80℃ 에서 2시간이 경과될 때, 소나무 시료보다 9.91% 정도 많았으나 4 시간이 경과되면서 두 시료의 함수량은 5% 정도로 급격히 저하되어 강한 인화성 건엽으로 전환되었다. 소나무 생엽과 생지 시료의 착화는 400℃의 가영온도에서 각각 약 7분 10초와 13분 20초에 일어났으며, 발염은 각각 약 12분 20초와 15분경에 일어났다. 생엽과 생지 시료의 연소온도는 가열온도와 관계없이 각각 76℃, 106℃ 상승했다. 400℃의 가열온도에서, 소나무와 잣나무 생엽 시료의 고온 지속시간은 각각 0-07'16", 0-07'08" 였으며, 600℃에서는 각각 0-04'45", 0-02'13"였다. 따라서, 고온 지속시간은 고온일수록 짧았다. 각 가열온도에 따른 연소온도와 최고 온도의 관계는 가영온도가 낮으면 상승되는 온도는 낮았고, 높은 가열온도에서는 높은 온도가 상승했다. 생엽과 생지 시료의 전연소열량은 대체적으로 각각 1253.4㎉ (21.5%), 1290.6㎉ (14.3%) 였으며 생엽 시료가 생엽 시료보다 약 37.2 ㎉ (7.2%) 더 적었다. Present study aims at examining how the amount of sample and changes in combustible temperature of fresh branches and leaves treated with heating temperature are associated with combustible time of two coniferous trees, Pinus densiflora (D) and Pinus koraiensis (K), which are the main victims of forest fire. During the first two hours at 80℃, moisture content of K was higher than that of D by 9.9%, but after four hours, the moisture content was both lowered by 5% and turned into highly combustible leaves. At 400℃ of heating temperature, catch-fire of fresh leaves and branches of D occurred in 0-07'10" and 0-13'20", and also burning times were 0-12'20" and 0-15'03", respectively. Also, with fresh leaves (D,K), the duration of high temperature was as follows: 0-07'16", 0-07'8" at 400℃ and 0-04'45", 0-02'-13" at 600℃, respectively. With fresh leaves and branches, the maximum combustible temperatures, regardless of heating temperature, were 76℃ and 106℃. Concerning the relation between the amount of burnt fuel and maximum temperature, the more amount of the former was, the higher the latter was. The total amount of combustion-heat of fresh branches and leaves were 1253.4 kcal (21.5%) and 1290.6 kcal (14.3%), respectively. So, fresh leaves were about 37.2 kcal (7.2%) less than fresh branches.

연골막판으로 싼 정제된 산호의 조직학적 연구

김지수,손대구,한기환,최동원,박관규 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.3

Autogenous costal cartilage graft has been commonly used for reconstruction of auricular deformity. However, the risk of complication and discomfort at the donor site, as well as distortion of the graft due to morphological change in the cartilage have been serious drawbacks to this procedure. Previous studies examining the chondrogenic potential of perichondrium have suggested that perichondrium may be used as graft for cartilage reconstruction. When a perichondrial flap or a free perichondrium was used as graft, new cartilage formed appositional to the grafted perichondrium. However, the neocartilage was often irregular in shape and varied considerably in quantity. In this study, the feasibility of controlling the shape and the mass of neocartilage was investigated using coral, a porous biomaterial, as a template. A coral a template was wrapped with perichondrial flap from the ears of New Zealand white rabbits and placed into a subcutaneous pocket in the rabbits and placed into a subcutaneous pocket in the rabbit's back by incision. A total of 12 animals were used. Formation of new cartilage was later evaluated by gross and histological examination of the perichondrial flap and the coral template. New cartilage was formed in 11 animals. Immature chondrocytes were visible by 3 weeks after the surgery, and by 8 weeks the immature chondrocytes had formed a cartilage. New cartilage was formed only on the surface of the coral template. These results indicated that the shape and the mass of new cartilage may be controlled by using coral template. Therefore, the desired shape of cartilage may be achieved using a coral template of corresponding shape, and this may help in correcting subtle auricular contour defect and in correcting other structural defects that also require new cartilage formation.
