Background and Objectives : To study the prevalence of ADHD in urban elementary school children using the Korean version of the disruptive behavior disorders parent rating scale. Materials and methods : 6,372 students from seven urban elementary schools were targeted using the parent rating scale. Results : (1)The total ADHD prevalence was 6.1%. It can be broken down as follows: 4.1% was the Inattentive type, 1.0% was the Hyperactive-impulsive type and 1.1% was the Combined type. 8.3% occurred in male students and 3.9% occurred in female students. The prevalence in boys was significantly higher. (2) The prevalence of Conduct Disorder(CD) was 0.3%: 0.2% for male students and 0.3% for female students. There was no significant difference between girls and boys. (3) The prevalence of Oppositional Defiant Disorder(ODD) was 4.4%: 5.0% for boys and 3.9% for girls. The value for boys was significantly higher. (4) A statistically significant difference between grades was found with ADHD, but no significant difference between grades was found with CD and ODD. (5) In the results of the comorbidity research, ADHD accompanied by CD was 2.3%. ADHD accompanied by ODD was 25.5%. ADHD accompanied by both CD and ODD was 4.1%. (6) Mild forms of ADHD, CD and ODD were found four times more often than that observed in typical cases. Conclusion : Prevalence of ADHD in urban elementary schools is high and CD or ODD is accompanied more frequently. In the future, the school mental health project should be focused mainly on ADHD. From the beginning of urban elementary schools, ADHD should be screened for. Intervention is required depending on whether or not there are accompanying diseases.

We have developed a simple and rapid method for the synthesis of a precursor solution used in the production of ?? thin films of the layered-perovskite phase ??. Precursor solution preparation takes less than 30 min and involves the generation of two solutions : (a) Bi(O₂CMe)₃dissolved in pyridine and (b) ?? added to Sr(O₂CMe)₂and than solutbilized by HO₂CMe. After stirring separately for 10 min, these solutions are combined, stirred for an additional 10 min, and used without any further modifications. Films of the layered-perovskite phase were formed at temperatures as low as 700℃. Ferroelectric testing of SBN films, films, fired at 800℃ reveals standard hysteresis loop with no fatigue for up to 4×10 cycles.

당근 육종 과정 중 유망계통으로 선발되는 기준인 선발 평점이 주로 어떤 형질들에 의해 크게 영향받는가를 알고자 하였다. 5년에 걸쳐 봄 재배작형으로 시험한 자료를 가지고 상관 및 경로계수 분석을 통하여 선발평점에 미치는 여러 형질들의 직ㆍ간접효과를 조사한 바, 각 형질의 선발 평점에 대한 기여도는 년차에 따라 달랐다. 따라서 가장 큰 직접효과나 간접효과를 나타내는 형질은 매년 변하였다. 그러나 거의 항상 비교적 높은 직ㆍ간접 효과를 나타내는 형질은 찾을 수 있었는데 이는 근중과 고환성이었다. 이들 다음으로는 엽장과 수경등이었다. 반면 엽수, 지근, 근형, 근피특성 등은 직ㆍ간접효과가 가장 작았다. This study was conducted to clarify the direct and indirect effects of major morphological characters affecting selection score of carrot. The field experiment was carried out five times from 1991 to 1995. Root weight, number of leaf, leaf length, crown diameter, root diameter, root length, branch root, root cracking, bolting, uniformity, root-tail form, root shape, leaf weight, total weight, smoothness of root skin, hypertrophy of root and selection score were investigated. No character constantly showed the highest direct/indirect effect. Therefore the character showed the highest direct/indirect effect changed year to year. But it was possible to find out which characters were more important, or not. In frequency of high-ranked direct/indirect effect, two characters, root weight and root-tail form, were considered more important. The next characters were leaf length and crown diameter. The lowest were leaf number, branch root, smooth of root skin, and root shape.

우수한 당근 품종육성을 위한 기초자료를 얻고자, 육성 계통들 중에서 선발된 재료를 사용하여 어떤 형질이 根重에 크게 영향하는가를 확인코자 하였다. 2년에 걸쳐 봄, 가을 재배작형에 대해 시험한 결과를 상관 및 경로계수 분석을 통하여 根重에 미치는 여러 형질의 직ㆍ간접효과를 조사한 바, 봄, 가을, 재배 년도의 구분 없이 葉重과 全重의 직접효과가 매우 컸고, 나머지 형질들의 직접효과는 크지 않았다. 직접효과에 있어서도 全重은 정의 방향, 葉重은 부의 방향으로 달리 영향하는 것으로 나타났다. 나머지 형질들 중 葉重, 根首徑, 根徑, 葉長 등은 根重에 대한 직접효과는 크지 않았지만 全重을 통한 간접적 효과가 인정되었다. This study was conducted to clarify the direct and indirect effects of major morphological characters affecting root weight of carrot. The field experiment was carried out two times in 1991 and 1995. Root weight, number of leaf, leaf length, crown diameter, root diameter, root length, branch root, root cracking, bolting, uniformity, root-tail form, root shape, leaf weight, total weight, smoothness of root skin and hypertrophy of root were investigated. Major characters which had a direct effect on root weight were leaf weight and total weight. Total weight contributed positively towards root weight, but leaf weight had a negative effect. Number of leaves, leaf length, crown diameter, and root diameter did not have a direct influence on root weight, but they affected indirectly on root weight through increasing of total weight.

The purpose of this study is to find to relationship among the children's peer status, friendship quality, and conflict resolution strategie in children's friendship. The object of this study were 417 children in 5th grade of elementary school in Seoul. The measuring instruments used for study were peer nomination developed by Coie and Dodge(1983), Friendship Quality Scale developed by Lee and Koh(1999) and a Scale on Friendship Conflict Resolution Strategies (Rhee, Koh & Oh, 2000). The Collected data was analyzed by SPSSWIN statistical program. The frequency and percentage were calculated to investigate the general characteristics of the subjects. One-Way analysis was performed to find relationship among the children's peer status, friendship quality Mutiple Regression was performend to find relationship among the children's peer status, friendship quality, and conflict resolution strategie in children's friendship. The major results of this study are as follows, First, concerning about peer status and friendship quality, pouplar group have a positive friendship but, rejected group have a conflictive friendship. Second, while popular group used various strategy in conflict resolution, neglected group used evasive strategy. Third, concerning about relation between quality of friendship and frienship conflict resolution strategy, while the group which has high degree of emotional stability, intimacy and human desire used negotiation, cooperation and concession strategy, the group with has low degree of cooperation and pleasure of friendship used evasion and away strategy. Fourth, concerning the effect of friendship quality according to peer status which influence conflict resolution strategy between friendship, each popular, average, rejected and neglected group gas different quality of friendship and according the lower factor of friendship quality, each group has different conflict resolution strategy. Therefore I suggest that according to the peer status, arbitration program should be selected with propriety.

The Purpose of this study was to separate of qualitative analysis toward the mixture of aqueous pen using chromatography in the unit the separation of the mixture in 4th grade elementary school science. Paper chromatography is basically a type of partition chromatography between water adsorbed onto the cellulose fiber of the paper and a liquid mobile phase in a closed tank. The most common application is the ascending solvent technique and circular developing methods. The paper is hung by means of clips or string and the lower end is made to dip into the eluting solvent. The porosity, adsorption and developing velocity were to investigate of filter paper and paper chromatogiaphy was to separate of a mixture aqueous color pen from using ascending of strips and circular paper chromatography of filter paper. The results are as following: First, Adsorption and development velocity depends upon porosity and particle retention of using filter paper. Second, First of all resolving power is good using chromato-strip that water is best in single developing solvents system and water/acetone (9:1) solvents is best in mixing solvents system using chromato-strip. Third, The resolving power of chromato-strip are very good on porosity and particle retention of filter paper and chromatography papers(2.5㎛>8㎛>11㎛>l㎜>3㎜>20-25㎛). Also the resolving power of using circular paper chromatography gave the same results (2.5/㎛>8㎛>11㎛>l㎜>3㎜>20-25㎛). I want to suggest to a pillar of a paper circular paper chromatography are suited for a short and a coarseness filter paper. The use of thick paper such as filter paper (6㎛), paper chromatography (3㎜) are available in principle similar to thin layer chromatography when used in the ascending method.
