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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

This paper is a study on the isolated word recognition using neural network and DTW(Dynamic Time Warping). We trained the three group neural networks using the phonetics {(ㅇ, ㄹ, ㅁ), (ㅅ, ㅊ, ㅍ, ㄱ), (ㅕ, ㅣ, ㅗ, ㅠ, ㅜ)} which were included in Korean digits. In order to recognize the total phonemes in Korean digits, we constructed the neural network in a modular fashion by exploting the hidden structure of previously trained three phonetic subcategory networks. And Isolated words were recognized by the DTW using phonemes found in the previous step.

장방형 십자류 유동층 전극반응기를 이용하여 0.02M의 황산동 수용액으로 부터 구리이온을 전착시키는 환원반응을 수행하면서, 시간에 따른 국부과전압 빈도와 입자층내 3차원 위치에 따른 시평균 과전압 분포를 측정하였다. 그 결과, 반응기 중간영역에 위치한 입자는 용해현상을 나타내었으며, 전착효과는 입자경이 크고 유속이 작을 때 우수 하였다. 또한, 본 연구에서 제시한 이론 모델식은 근사적으로 실험치를 예측할 수 있었다. The reduction of cooper ion in the 0.02M CuSO₄electrolyte has been performed in a rectangular side-by-side fluidised bed electrode reactor. The distributions of the mean overpotential along each of three coordinates in the bed have been measured. Under the some experimental conditions in this work,the particles of the inner bed were not desposited but dissoluted. The diposition reaction rate increased with increasing the particle diameter and decreasing the fluid velocity. The theoretical model in this work predicted the experimental values of the overpotential appoximately.

The main purpose of a classification system is to provide a mental picture of the injury and also information as to treatment a prognosis. At present, Lauge-Hansen classfication has improved the results of conservative treatment, and Danis-Weber classification which was taken by the AO(ASIF) group was designed for application to operative treatment. But, both system have dificiencies, Recently, the proposed classification system by M. Tile which was based on the ankle stability was interesting. So, compared among the system for identification that these systems are synonymous or if not, one system has a distinct advantage over the other. Total 135 patients, 135 cases have been reviewed at CNUH from January, 1983 to December, 1988. The results were as follows: 1. We considered that it was very difficult to classify the ankle fractures by Lauge-Hansen system because of complexity and variable fracture patterns. But, we have been classified the fractures abut 98.5% by simplification of medial malleolar frecture patterns. 2. Danis-Weber classification was simple and easily applicated, but it was not helpful for decision of the amount of injury, treatment and prognosis. 3. The proposed M. Tile classification added to a aspect of the stability, so it was helpful for descision of the treatment methods. Also, this system classified the isolate medial malleolar freature that was not by Danis-Weber classification. 4. From the above results, we consider that by Lauge-Hansen classification, can be identify the occult ligament injuries, and by M. Tile classification, deside the treatment methods.

Objectives : This study intended to obtain the interrelationship of lead exposure indices and anemia related factors for the better health management of lead exposed workers. Methods : 502 male workers in storage battery industries as lead exposed group and 106 male office workers as contorl group were selected for this study. The examined variables wer age, work duration, smoking and alcohol crinking habit, blood zinc protoporphyin concentraion (ZPP), blood lead concentration (PbB), urinary δ-aminoevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct), serum calcium (S-Ca), serum iron (S-Fe), total iron binding capacity (TIBC), and percentage trasferrin saturation (PTS). Results : The means of ZPP, PbB ALAU in lead exposed proup were 58.4±35.7 ㎍/㎗, 27.6±10.9 ㎍/㎗, and 1.61±2.00 mg/ℓ, respectively. These three values in lead exposed group were significantly higher than control group (P<.05). The means of Hb, Hct, S-Ca, S-Fe, TIBC, PTS in lead exposed group were 15.3±1.1 g/㎗, 47.2±4.5 %, 9.4±0.4 ㎍/㎗, 124.0±67.5 ㎍/㎗, 317.1±68.5 ㎍/㎗, and 38.7±15.2 %, respectively. Hb, Hct, S-Ca, S-Fe, and TIBC in lead exposed group were significantly lower than contrl group (P<.05). PTS was no significant difference in lead exposed group and control group (P> .05). Hct, S-Ca, S-Fe, PTS were significant positive correlation with Hb and ZPP, corrected PbB, AlAU were significant negaitive correlation with Hb in lead exposed group (P< .05). On multiple regression using ZPP as a dependent variable and PbB, S-Ca and S-Fe as independent variables after adjustment for possible confounder such as age, smoking and drinking habit, Pbb, S-Ca, S-Fe and age contributed to ZPP. Conclusions : As the result of this study, it was suggested that inclusion of S-Ca, S-Fe, PTS measurement as a anemia screening test for lead workers was highly recommended for the effective prevention and early diagnosis of anemia.

This paper describes objective quality measures for various kinds of speech waveform coding systems (Pulse Code Modulation, Adaptive Differential PCM, Continuously Variable Slope DM, first-order Constant Factor DM). Three objective measures of speech waveform coding systems were used Segmental SNR, LPC-CD (Liner Predictive Coefficient Cepstral Distance), FFT-SD(Fast Fourier Transform Spectral Distance). And speech data corrupted channel code error were measured by the above objective quality measures. Through the simulation of the two types of speech data, PCM showed better performances in the all objective test.

Spontaneous intracranial hemorrage is rare in the childhood, which is usually caused by vascular anomalies, blood dyscrasia and trauma. A 15-year-old child presented with sudden headache while he was studying. The fretures of radiologic images suggested the cerebellar hematoma caused by the underlying lesion such as vascular malformation or cavernous hemangioma. The operation finding revealed that the hematoma was caused by a tumor, which adhered to the superior medullary velum of cerebellum. The pathology revealed it to be hemorrhagic pilocytic astrocytoma. The hemorrhagic pilocytic astrocytoma should be considered in the diagnosis of the lesion in cerebellar hematoma.
