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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

Silicon nitride Si₃N₄ is a leading ceramic for structural applications due to its superior properties at high temperature. It is very difficult-to-grind ceramics with high efficiency because of their high strength, hardness and brittleness. In this paper, ultra-precision surface for Si₃N₄ ceramic were using MR polishing method. MR Polishing experiment were using the magnetorheological fluid and Polishing abrasives are Al₃O₃. Polishing experiments were under various polishing conditions by changing a magnetic field force, wheel speed and polishing time. Polishing surfaces were observed analyzed by non-contact type 3-dimensional surface roughness measurement equipment. As a result, MR Polishing method can give excellent surface roughness, and surface roughness was obtained Ra=1nm.

목적: 한국에서 알레르기 질환 치료를 위한 한방 치료뿐만 아니라 대체 요법이 많이 이용되고 있으며, 그 현황에 대하여 다기관 조사를 시행하였다. 방법: 10개의 대학병원 외래로 내원한 647명의 알레르기 환자를 대상으로 설문조사를 시행하였으며, 이 중 510명이 한방 이외의 대체 요법에 응답하였다. 이환되어 있는 알레르기 질환은 천식(50.0%), 알레르기 비염(36.0%), 아토피 피부염(36.0%), 그리고 두드러기(9.3%)였다. 각각 환자들에게 12 문항의 설문조사를 시행하였으며, 한방 이외의 대체 요법의 사용 빈도 및 종류, 대체 요법에 의지하게 된 이유, 비용, 그리고 치료효과에 대한 의견을 물어 보았다. 결과: 16.7%의 알레르기 환자에서 한방 이외의 다른 대체 요법을 받았으며, 평균 1.6종의 한방 이외의 대체 요법을 받았다. 가장 많이 의지하는 대체 요법은 민간 식이요법 (48.6%)이었고, 그 다음이 아로마 요법(23.8%), 지압(14.3%), 건강 호흡법(7.6%), 마인드 컨트롤(5.7%), 목욕요법(5.7%) 순이었다. 대체 요법을 받은 환자 중 마인드 컨트롤(50%), 식이요법(50%), 그리고 건강 호흡법(75%)의 경우 치료 효과가 만족스럽다는 응답이 높았으며, 목욕요법, 아로마 요법, 그리고 지압은 만족도가 각각 33.3%, 28.0%, 26.7%로 저조하였다. 대체 요법 사용자의 63.6%가 5회 미만의 대체 요법을 받았고, 91.8%가 1년 이내로 치료받았으며, 1인당 평균 연 37 만원을 지출하였다. 대체 요법을 선택한 가장 큰 이유는 체질이 개선될 수 있을까 해서(44.2%)였으며, 대체 요법이 몸에 부담이 없어서(31.4%), 면역기능이 강화되어서(22.9%) 순으로 나타났고, 15.7%는 양약치료가 도움이 되지 않아서 대체 요법을 선택하였다고 응답하였다. 결론: 한국에서 알레르기 환자의 상당수가 한방뿐만 아니라 여러 가지의 대체 요법을 사용하고 있음을 알 수 있었다. 대체 요법의 사용 빈도가 증가하고 그 종류가 다양함을 고려할 때, 의료진은 대체 요법의 현황에 대하여 정확히 인지하고 이에 대해 관심을 가지고 환자를 대하여야 하며 올바른 알레르기 질환 치료법에 대해 환자뿐만 아니라 의료인에게 교육하는 것이 필요하다. Background/Aims: The use of unproven complementary/alternative medicine (CAM) to treat allergies is popular in Korea. We conducted a multicenter survey of the current use of CAM other than herbal medication in Korean allergy patients. Methods: This study enrolled 510 adults with allergic diseases, including asthma, allergic rhinitis, atopic dermatitis, and chronic urticaria, from ten hospitals. They underwent a structured questionnaire interview and clinical assessment of the prevalence, motivation, costs, and subjective assessment of CAM. Results: Of the patients, 16.7% used at least one type of CAM to treat their allergic diseases. Common types of CAM were diet (48.6%), aroma therapy (23.8%), massage (14.3%), breathing exercises (7.6%), baths (5.7%), and mind control (5.7%). The therapeutic effects of CAM included improved in patients using mind control (50%), diet (50%), breathing exercises (75%), and baths (33.3%), but worse in patients using aroma therapy (28%), and massage (26.7%). About 36.4% of the patients used CAM more than four times per year, and the average cost per CAM user was 370,000 won/year. The main reason for trying CAM was `hope to improve my constitution`. Conclusions: CAM is used widely for treating allergic diseases in Korea. Detailed knowledge of CAM and patient education are important. Further studies of the clinical efficacy of CAM are needed.

The water level and flow rate data measured at Indogyo measurement point which serves as one of the major measuring points of Han River have been very important in aspect of controlling the flow. Because these data are becoming more and more unreliable due to the recent change in the basin or the narrowing of the river width, these data will be standardized by comparing the recent data of Indogyo measuring point with the past those. To minimize the errors of water level-flow rate curve caused by the yearly changes of basin, the standard water level-flow rate curve with respect to the present basin conditions will be set, and calculated reduced water level will be compared with the past data. And through frequency analysis, frequency-based flood level with respect to return period will be presented. Finally, the total flow rate of the flood measured in September, 1990 at the point of Indogyo measuring point will be compared with the total flow of the past extreme floods.

Fingerprint patterns of 333 schizophreniacs who met with the diagnostic criterias of International Pilot Study of Schizophrenia except items associated with chronicity in exclusion criteria were studied, and the following results were obtained. 1. The frequency distribution of the fingerprint patterns in the 333 schizophreniacs was ulnar loop, whorl, twinned loop, arch, radial loop in order in both control and schizophrenia groups. 2. Finger ridge counts of both sexes were decreased significantly in schizophrenia group. 3. Dissociation of fingerprint pattern in the schizophrenia group was 51.1%, which was far greater than 6.25% of control group. Number of dissociation was greatest in the thumb, followed by index, middle, ring, and little finger in order. According to the above results, it is considered that both the number of finger ridges and degree of dissociation of fingerprint patterns were closely related with schizophrenia. Analysis of fingerprints and palmprints with the aid of chromosomal analysis would contribute the early diagnosis and prevention of schizophrenia.

A study has been undertaken to know the reason why the white specks appear in the polyethylene terephthalate (PET) filament fabrics which were made alkali weight loss treatment in the dyeing and finishing factories of Taegu area. The results are as follows 1. Main component of the white spects in PET filament fabrics is CaCo₃. 2. The CaCO₃was extracted from the washing water and adhered to the PET filament fabrics during the dyeing and finishing process. 3. When PET filament fabrics were treated with hard water, the warp sizing agent did not dissolve to make specks on dyed fabrics. Then the insoluble sizing agent can not be got rid of by alkali treatment. 4. On account of using Na₂CO₃ in washing PET filament fabrics, white spects also can be appeared.

This study was performed to evaluate the actual temperature rise on the surface of Buchanan plugger using thermocouple. The heat carrier system 'System B Heatsource'(Model 1005, Analytic Technologies, Redmond, WA, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ on digital display and the power level on it was set to 10. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 mm increments from the tip to the 4 mm length of shank. The heat control spring was touched for 5 seconds, and temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01 using Data Logger. The data were statistically analyzed by one-way ANOVA. The results were as follows. 1. The position at which the temperature peaked was approximately at 1~2 mm far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F plugger and followed by, in descending order, FM plugger, M plugger. ML plugger showed the lowest peak temperature (p<0.01). 3. The temperature on the pluggers was decreased with the increase of touching time. This results suggest that the actual temperature on the surface of the pluggers dose not correlate well with the temperature set on digital display. Heat concentrates around the up. The larger plugger reveals lower temperature rise relatively.

A 14-year-old male pomeranian was present with swollen left ear. The swelling occurred from base to apex of pinna. Otitis externa persisted for two years. Hematological and serum biochemistry values were not remarkable. The surgery treatment was the most appropriate method among indwelling drain, surgical, and steroid treatment in the aural hematoma because the dog was very sensitive to touching pinna and the size of aural hematoma. Longitudinal incision was applied after general anesthesia. Cefovecin was injected to prevent secondary infection. The outcome of surgery was good. There was no evidence of recurrence for one year.
