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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

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.

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.
