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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

Volatile organic compounds(VOCs) are emitted as air pollutant from many petrochemical process. The measurement for these materials are difficult, because of a very little amount existed in atmosphere. This study was conducted in order to investigate the limit of detection(LOD) and limit of quantitaion(LOQ) for VOCs measurement. The concentrations of VOC's LOD and LOQ were assayed by gas chromatography with flame ionization detection(GC/FID). The results are as follows; 1. LOD and LOQ of acrylonitrile were 0.0114㎍/㎖, 0.0144㎍/㎖, respectively. 2. LOD and LOQ of benzene were 0.0136㎍/㎖, 0.0150㎍/㎖, respectively. 3. LOD and LOQ of 1.3-butadiene were 0.0114㎍/㎖, 0.0136㎍/㎖, respectively. 4. LOD and LOQ of 2-butanone was 0.1016㎍/㎖, 0.1073㎍/㎖, respectively. 5. LOD and LOQ of carbon Tetrachloride were 0.0065㎍/㎖, 0.0188㎍/㎖, respectively. 6. LOD and LOQ of c--hexane were 0.0112㎍/㎖, 0.0143㎍/㎖, respectively. 7. LOD and LOQ of ethylbenzene were 0.0112㎍/㎖, 0.0131㎍/㎖, respectively. 8. LOD and LOQ of n-hexane were 0.0172㎍/㎖, 0.0582㎍/㎖, respectively. 9. LOD and LOQ of styrene were 0.0122㎍/㎖, 0.0142㎍/㎖, respectively. 10. LOD and LOQ of tetrachloroethylene were 0.0121㎍/㎖, 0.0320㎍/㎖, respectively. 11. LOD and LOQ of 1.1.1-trichloroethane were 0.0016㎍/㎖, 0.0062㎍/㎖, respectively. 12. LOD and LOQ of trichloroethylene were 0.0064㎍/㎖, 0.0183㎍/㎖, respectively. 13. LOD and LOQ of toluene were 0.0136㎍/㎖, 0.0148㎍/㎖, respectively. 14. LOD and LOQ of xylene were 0.0140㎍/㎖, 0.0154㎍/㎖, respectively.

This experiment was conducted to obtain some basic imformation for korean native oriental melon breeding. Genetic variability, heritability, and correlation on 13 characters were analyzed. The results are summarized as follows; 1. Among 13 characters, plant height and length of lateral shoot showed high level of GCV(110-362%) and ECV(89-101%). The rest characters showed low level of GCV(7-21%) and ECV(0.16-9%). 2. Heritabilities of 13 characters investigated were high as over 50%. Especially those of hypocotyl length, 100-seed weigth and seed width were very high (> 95%). 3. High level correlation values were observed among seed characters and seedling characters. 4. Plant characters of early growth stage, except leaf stalk length, were not related with characters of seed or seedling 5. In early plant growth stage, plant height and length of lateral shoot were correlated positively with number of node, number of lateral shoot, leaf length and leaf width.

A range of indicators is available to assess renal dysfunction in lead exposure. This study was undertaken to find out which indicators were most valuable as markers of renal dysfunction. We selected 75 male workers from the secondary lead smelter, plastic stabilizer and radiator manufacturing industries (the "exposed" group) and 64 male office workers (the "control" group). Blood lead; blood zinc protoporphyrin; urine lead; urine coproporphyrin; δ-aminolevulinic acid dehydratase activity; and urine δ-aminolevulinic acid were chosen as indicators of lead exposure. Blood urea nitrogen; serum creatinine; serum uric acid; N-acetyl-β-D-glucosaminidase; urine albumin; urine α₁-microglobulin; and urine β₂-microglobulin were used as indicators of renal dysfunction. Urine α₁-microglobulin level was significantly associated with the lead exposre level. Blood urea nitrogen, urine N-acetyl-β-D-glucosaminidase and urine α₁-microglobulin levels were highly correlated with indicators of lead exposure. Urine α₁-microglobulin had the highest correlation with other indicators of renal function. In addition, the proportion of subjects with high urine α₁-microglobulin levels showed a gradient with lead exposure. Conclusively, blood urea nitrogen, urine N-acetyl-β-D-glucosaminidase and urine α₁-microglobulin are useful indicators, but urine α₁-microglobulin is the early and the most valuable indicator of renal dysfunction related to lead exposure.

환시가 있는 정신분열병 환자가 어떻게 환시를 지각하고 있는지 이해하고 그들의 정신병리를 파악하여 효과적인 평가 및 치료에 도움을 주고자 본 연구를 시행하였다. 1991년 3월 1일부터 1992년 2월 28일 까지 DSM-III-R의 진단기준에 따라 정신분열병으로 입원한 환자 중 현재 지각하고 있는 환시를 그린 환자 40명을 대상으로 환시의 의미와 내용, 환시에 대한 정서적 반응 및 행동을 조사하였다. 또한 환시군과 대조군과의 간이정신상태검사와 간이정신평정척도를 비교하였으며, 환시의 의미와 환자의 망상 형태사이의 상관성, 환시에 대한 믿음의 강도, 환시의 빈도, 일회 삽화기간과 간이정신평정척도와의 상관성, 환시군의 간이정성평정척도 각 항목간의 상관성을 조사하였으며 결과는 다음과 같다. 1) 지각하고 있는 환시의 대상은 사람의 형태를 지닌 신화적인 인물, 의미는 피해적, 위치는 일상적 시야 범위 내의 근접거리, 빈도는 일주일에 한번 미만, 일회 삽화기간은 1∼5분, 정서적 반응은 부정적 반응, 환시에 대한 행동은 언어적 행동 또는 제한된 신체적 행동이 가장 많았다. 2) 환시의 의미와 망상의 내용사이에는 정적인 상관관계가 있었다. 3) 환시군은 환시 및 환각이 없는 군에 비해 불안, 환각적 행동, 비일상적 사고내용이 유의하게 많았다. 4) 환시 사실성에 대한 믿음의 강도와 환각 행동, 일회 삽화기간과 불안, 긴장, 운동성 지연 간에 정적인 상관이 있었다. 5) 환시군에서 간이 정신평정 척도상 환각적 행동항목과 불안, 환각적 행동과 매너리즘과 기묘한 자세취하기, 환각적 행동과 흥분, 환각적 행동과 운동성 지연에 각각의 정적인 상관이 있었다. 또한 운동성 지연과 긴장감, 무딘 감정과 긴장감, 감정적으로 움추러듬과 긴장감 사이에 각각 정적인 상관이 있었다. 본 연구의 결과들은 정신분열병 환자가 환시를 실제로 어떻게 지각하고 있는가를 임상가가 평가해야 하는 필요성을 나타내고 있다. Objective : The purpose of this study was to investigate actual visual hallucinations as perceived by 40 schizophrenic patients and, subsequently, to explore their psychopathology in order to assist clinicians in more effectively evaluating and treating the visual hallucination. Methods : With the authors' guidance, the content and meaning of pictures drawn, according to their perceptions, by 40 schizophrenic patients were evaluated in conjunction with an examination of the patient's emotional reaction and associated behavior. The results from the visual hallucination group were analyzed and then compared with non-visual hallucinatory control group using the Brief Psychiatric Rating Scale(BPRS). On this basis, the authors investigated the correlations between patients' strength of confidence in visual hallucination, frequency of visual hallucination, mean duration of an episode and the score of BPRS, and the correlation between meaning of visual hallucination and the type of patient's delusion. Finally the authors attempted to derive correlation among the items of BPRS. Results : 1) The content of visual hallucination was mostly non-human and mythologically exhibiting anthropomorphic qualities while its meaning was frequently persecutory. In addition, the visual hallucinations experienced by the subjects were most often close to or within the patients' ordinary visual range with mean duration of hallucinatory episodes ranging from 1 to 5 minutes. The most frequent reaction of patients is a negative emotional response and the most frequent overt behavior was either verbal or restricted physical activity. 2) There was a positive correlation between the meaning of the visual hallucination and the type of patients' delusion. 3) The group having visual hallucinations had more frequent anxiety, hallucinatory behavior and unusual thought content compared to the non-visual hallucination group. 4) There were positive correlations between patients' strength of confidence in visual hallucination and hallucinatory behavior and among anxiety, tension, motor retardation and mean duration of episodes of visual hallucination. 5) There were positive correlations between hallucinatory behavior and anxiety, hallucinatory behavior and mannerism and posturing, hallucinatory behavior and excitement, and hallucinatory behavior and motor retardation. Also, there were positive correlations between motor retardation and tension, blunted affect and tension, and between emotional withdrawal and tension among each item of BPRS in the visual hallucination group. Conclusion : In this study of visual hallucinations in schizophrenics, the authors concluded that it is helpful for clinicians to evaluate how schizophrenic patients experience their visual hallucination.
