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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher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

The true heartache is a condition of severe heartache corresponding to angina pectoris, as recorded from Hwang Jae Nai Kyung. According to the literatural study of true heartache, some results can be acquired, such as follows. 1. The site of the true Heartache, can be divided into two categories, first, its superficial and conscious area is the chest as same as the other heartache. But its inner lesion is the Heart-Meridian as others occupied at the Pericardium-Meridian in stead of the Heart-Meridian. 2. The etiological classification of true heartache, are Cold-evil, Heat-evil, Wind-evil, Blood stasis etc. But its major factor is Cold-evil, more than anything else. 3. The symptomatic signs of true heartache, consist of cyanotic change from hands and feet to phalanges; severe heartache pale complexion with cold breathing and its extreme state can manifestate unceased sweating called as Yang exhaustion.

이경섭 東新大學校 工業技術硏究所 1997 工業技術硏究 Vol.3 No.-

In this paper, we observed and theoritically analyed the mechanism of the displacement current for stimulation transmit by the displacement current measurement method. And the orientational change of molecules in monolayers was discussed on the basis of the Maxwell-displacement-current obtained. It was known that Maxwell displacement current was generated for monolayers on the water surface by compression. Therefore, we applied to the study of monolayers of Dipalmitoylphosphatidyl choline (L -α- DPPC). As results,the displacement was generated when the area per molecule about 180Ų in low pressure, and it was generated when the area per molecule about 110Ų in high pressure. Finally,we measured the differential thermal analysis(DTA) of sample. Phase transition was showed at 124.6℃ by DTA.

이광식,윤경섭,김형중,김호일 한국환경농학회 2003 한국환경농학회지 Vol.22 No.2

1990년부터 2001년까지 농업용수 수질측정망 조사자료를 분석하고, Chl-α 농도와 유효저수량/만수면적비를 이용하여 498개 저수지에 대하여 유형을 분류하고, 각 유형에 대한 수질개선방안을 제시하기 위하여 본 연구를 수행하고 다음과 같은 결론을 얻었다. 우리 나라 농업용 저수지의 Chl-α 농도는 유효저수량/만수면적비(ST/WS)에 민감하게 반응하였으며, ST/WS비가 클수록 Chl-α 농도는 감소하는 경향을 나타내었는데, 저수지의 부영양화를 억제하기 위해서는 ST/WS비를 최소 5~6 m 이상, 가능하면 10m 이상이 되도록 건설ㆍ보수하는 것을 좋을 것으로 판단된다. 우리나라 저수지를 Chl-α 농도 25 mg/m³, ST/WS비 5m를 기준으로 유형을 분류하고 그 특성을 고찰한 결과 ST/WS비가 작고 부영양화가 진행된 종합정비형인 Ⅰ형 저수지는 호소의 지형학적 특성과 외부에서의 부하가 모두 복합적으로 부영양화에 영향을 준 것으로 판단되며, 동일한 형상이라도 부영양화가 진행되지 않은 호내정비형인 Ⅱ형 저수지는 상대적으로 외부 유입이 적은 것으로 나타났다. 반면에 지형학적 특성상 수질관리에 유리한 ST/WS비가 큰 관리형인 Ⅳ형 저수지는 대부분이 부영양화가 아직 진행되지 않았으며, 유역으로부터 높은 부하량을 나타내는 유역정비형인 Ⅲ형는 부영양화가 이루어 졌으나 전체 저수지의 약 5% 미만으로 극히 드문 것으로 나타나 ST/WS비가 큰 경우 상대적으로 외부유입으로 인한 부영양화는 작은 것으로 나타났다. 수질개선사업우선순위(안)는 Ⅰ형(종합정비형) → Ⅲ(유역정비형) → Ⅱ형(호내정비형) → Ⅳ형(관리형)의 순으로 정비해 나가는 것이 바람직할 것으로 판단된다. 또한 농업용수 수질기준 항목 중 COD 농도를 유기오염 지표뿐 아니라 부영양화를 나타내는 지표로써도 함께 고려하여 세분화한 결과 현행 8 mg/L에서 10 mg/L 이상을 대책기준, 6~10 mg/L을 우려기준, 6 mg/L이하는 안전기준으로 세분하고, 이에 따라 수질개선사업을 실시하는 것이 효율적일 것으로 판단된다. A total of 498 agricultural reservoirs ranging from 164 × 10³ to 253 × l0^(6) ㎥ in storage volume were investigated from 1990 to 2001 with respect to Chl-a, COD concentration and pollutant loading of BOD, TN, and TP. The lakes and reservoirs could be classified to 4 types using the relationships between the ratio of storage volume per water surface area(ST/WS) and Chl-a concentration. It is recommended that the improvement of polluted lakes should be performed in the order of integrated consolidation type→watershed consolidation type→in-lake consolidation type→management type and reservoir should be constructed to be over 5∼6 m in depth(STWS ratio) for preventing the eutrophication of agricultural reservoirs. We propose that water quality criteria for agricultural water is changed from less than 8 ㎎/L to less than 6㎎/L for safety value, 6-10 ㎎/L for concern value, and more than 10 mg/L for countermeasure value in COD concentration, respectively.

이경화,김정섭,유현철,최성우,윤철종,우성훈,박승조 동아대학교 환경문제연구소 2001 硏究報告 Vol.24 No.1

Adsorption equilibrium of heavy metals ion on the peat moss was confirmed Frundlich isotherm Removal efficiency of heavy metals ion was increased from pH 2 to 10 and heavy metal removal efficiency was increased in the sequence of Cu(Ⅱ) > Pb(Ⅱ) > Cd(Ⅱ) > Mn(Ⅱ) on the PM(Peat Moss). The PM is likely to be more effective adsorption than the PAC to removal of metal ions in the solution, since PM's weakly acidic functional groups which is not founded on the PAC, in addition to its high surface area and porosity. But, the PM is not separated from the solution water by sedimentation process. So, a liquid and solid seperation between the PM and the solution water could be considered for the PM's field application. But peat moss was low cost adsorbent. Thus author propose to adopt PM as a adsorbent for heavy metal removal.

An electrical technique that allows the reorganization of single mono layers to be probed by measuring the Maxwell-Displacement-Current (MDC) flowing across mono layers was described. The maxwell displacement current was generated from single mono layers with the application of an external stimulus (pressure, light or heat) in the absence of an external electric field. In this paper, We measured the surface pressure, displacement current and the dipole moment of phospholipid mono layers on the water surface with a applied pressure by MDC.

中高等學校時間配當에 關하여 : 新舊敎育科程을 比較하면서 Comparing the New Curriculum with the Old

李慶燮 慶北大學校 1964 論文集 Vol.8 No.-

Curriculum is the material or method to achieve the established educational objectives. Therefore the critisism of the allotment of time which we will undertake as practical criteria of the curriculum must be originated from the educational objectives. When we looked from the point of view, we found that there was a little difference in educational objectives between the old curriculum and the new one. Instead of "creation of world civilization, inquiry of knowledge and reasonable life" attitudes found in the old curriculum, productivity, development of individuality and basic learning were emphasized in the new curriculum. Since in the new curriculum independence, productivity and utility are emphasized, haying close relationships to a practical life. we can see that the practical tasks facing us should be well reflected in the subjects. However, we find that the objectives of the new curriculum mentioned above do not agree entirely with the allotment of time. We can show examples as follows: In the allotment of time for middle school, the reason for the increase of time in language, physical education, music and fine arts can be seton to be closely related with basic learning, civic hygience, and the development of individuality which were given the importance in the objectives of the new curriculum. But, in spite of the fact that the democratic belief and its life, and the teaching of science to improve the economic life of our country were greatly emphasized in the objectives of the new curriculum, the allotment of time in the social studies and science was decreased. Besides, though basic learning was emphasized, the allotment of time for mathematics was not changed between the old curriculum and the new one. In the allotment of time in high school, the increase of total hours in physical education to emphasize the importance of health can be taken as good ; but, even though basic learning, the democratic belief and its life, and independence were important, the total hours in mathematics and social studies were decreased. Though the improvement of our economy and productivity were greatly emphasized, the total hours in science, home making or fussiness were not particularly emphasized. Taking all these facts into consideration, we can sty that the objectives and practices do not agree with each other. The above instances are all about comparison between the old curriculum and the new one. When we compare our the allotment of time in our new curriculum with that of the foreign curriculum, there are some improvements that should be made in our curriculum. for examples: In comparison with the foreign curriculum, we find that the percentages of hours in science and mathematics in middle and high school are low. On the other hand, percentages of hours in physical education in high school are amazingly high, and the total hours a week in middle and high school are very high. All this must be improved more reasonably.
