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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

In order to improve the fracture toughness of alumina-Mo composite, three-component systems has been studied : Al₂O₃-Mo-CeO₂, Al₂O₃-M0-(TZ-2Y), and Al₂O₃-Mo-(Ce-TZP). The particle size and volume fraction of Mo in alumina were fixed at 0.6㎛ and 5 vol.%. The microstructural change and the fracture toughness of these systems were analyzed. When the Ce-nitrate as CeO₂source was added, Mo and Ce-β-alumina were observed in the alumina matrix. When 2 mole% of Ce-nitrate was added as colloidal form, the composite showed a maximum fracture toughness(about 5.8MN/m?). However, standard deviaton of fracture toughness was large because of the nonhomogenity of the microstructure. On the other hand, when Ce-nitrate was added as solution, the higher the Ce-nitrate content, the lower the fracture toughness of the composite. When the TZ-2Y was added, Mo, ZrO₂(m), and ZrO₂(t) were observed in the alumina matrix. This composite showed a maximum fracture toughness(about 5.2MN/m) at 15 vol.% of TZ-2Y. When the Ce-TZP was added, Mo, Ce-β-alumina, ZrO₂(m), and ZrO₂(t) were observed in the aluminal matrix. This composite showed a maximum fracture toughness(about 6.3MN/m?) at 30 wt.% of Ce-TZP. This value is larger than that of hot pressed alumina/0.6 ㎛-5 vol.% Mo composite(about 6.1MN/m?).

Wingate test 및 Supramaximal exercise를 이용한 무산소성 운동능력의 측정시 나타난 변인의 관련성을 살펴본 본 연구를 요약하면 다음과 같다. Wingate test시 혈중젖산농도 최고치는 9.04±0.62mM로서 Supramaximal exercise시 보다 유의하게 높았으며, 혈장 LDH 및 CPK활성도는 두가지 운동부하후 모두 유의한 변화는 나타나지 않았다. 근전도상의 적분치, 중간파형빈도 및 평균파형빈도도 유의한 변화는 없었다. 등속성 수축시의 최대토오크는 양쪽 다리 모두에서 초당 60도의 각속도에서가장 높았다. Wingate test시의 최대파워는 등속성 수축시 최대토오크 및 Wingate test시 중간파형빈도의 직접적인 영향을 받는 것으로 나타났으며, 평균파워는 Wingate test시의 적분치 변화, 듣는 쪽 슬관절의 등속성 수축시최대토오크 및 Supramaximal exercise시 혈장 LDH 활성도의 직접적인 영향을 받는 것으로 나타났다. 이상의 결과에서 무산소성 운동능력과 관련지어 그 기전을 살피고자 할 때 체내 화학적 변화, 전기생리적 변화 및 발현능력의 복합성을 고려해야 하며 최대누적 산소결핍량의 활용가능성은 측정강도 결정방법을 중심으로한 계속적인 연구가 요구된다. The present study examined the relationship of variables related to anaerobic capacity with Wingate test and supramaximal exercise. Peak value of blood lactate concentration with Wingate test showeda significantly higher than suprammaximal exercise, and plasma LDH & median power frequency and mean power frequency were not any difference between two tests. Peak torque of isokinetic contractionh on knee joint showed a highest value in 60 degrees of angular velocity among a various angular velocity. Peak power of Wingate test was related to peak torque of isokinetic contraction and median power frequency of EMG with Wingate test, and mean power of Wingate test was related to integrated EMG with Wingate test, peak torque with isokinetic contraction of dominant knee joint and plasma LDH activity with supramaximal exercise. In this result, when it analyzed the mechanism of anaerobic capacity, ti was required the consideration of complexity according to biochemical alteration, electrophysiological alteration and revelation of performance, Appicapability of maximal accumulated O₂deficit was demaned a continuous study with the focus of exercise intensity.

Pilomatricoma is a benign adnexal tumor differentiating toward elements of the hair matrix and shaft. It typically presents as a solitary, deep, dermal nodule, but other variants, such as anetodermic form and pseudo-bullous form have rarely been reported. A 22-year-old man presented with erythematous 4×5㎝ sized bulla-like nodule of about 1 month history on the upper back. Histopathologic examination of the lesion showed a well-circumscribed dermal nodule composed of basophilic cells, shadow cells, and transitional cells. There were also marked lymphangiectatic dilatations above the tumor in the upper dermis. We diagnosed this case as a lymphangiectatic pilomatricoma with pseudo-bullous appearance.

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two experts familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further ckecked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NIOSH method 7400. The air-borne asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7-1.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 subjects, there were 4(3%) definite asbestosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.

We have compared with the transmittance of multi-coated CR-39(-0.25D) lenses in using the ocular shop from results of the spectrophotometer. The lenses prepared in A, C, and E company show low transmittance characteristics than ones a no-coated CR-39(-0.25D). This means a bad-quality coating effects. The lenses of B and D company show a good transparancy in visible spectral range.

A Michelson interferometer was used for the purpose of measuring the refractive index of air as a function of its respective pressure. The He-Ne laser was used as its light source. Following empirical relationship between refractive index and pressure was deduced from experimental data, as shown below, n=1+(3.5±0.1)X10^(-7)·P The calculated values of index of refraction for air at 1 atmospheric pressure is n_(air)=1.00027, which are in good agreement with its found in the literature.
