Objective：There is increasing interest in the developmental relationship of parental psychopathology and parenting behavior and conduct disorder in adolescence. The object of this study is to investigate the role of parental rearing behaviors in influencing conduct disorder in adolescence comparing with normal adolescents. Methods：The author assessed 52 conduct disorder who met the DSM-Ⅳ criteria, and 144 normal control subjects using self-report questionnaires, 'The Parental Rearing Behavior Scale'. Results：The results of study were as follows：1) There is significant correlation between the conduct disorder group and the control group in the father’s anxious emotion subscale, not mother’s. 2) There is no significant correlation between the conduct Disorder group and the control group in other subscales such as affection, hostility, rational guideline and consistent limitation subscales. Conclusion：The results suggest that father’s psychopathology including overanxious parenting style will predispose a risk factor for conduct disorder than mother’s psychopathology.

The present study was investigate the effects of feedback on mathematical achievement and attitude toward mathematics. Referring to the improvement of mathematics achievement, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there found no significant differ between group I and II(p>.05). As for the poor level of mathematics achievement, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there for fine level, found no significant differ between feedback group(group I and II)and the normal learning group(group III)(p>.05). Referring to the improvement of attitude toward mathematics, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there found no significant differ between feedback groups(group I and II)and the normal learning group(group III)(p>.05). As for the level(find or poor) of mathematics achievement, feedback groups(group I and II) turns out to be more efficient than the normal learning group(group III)(p<.05), there found no significant differ between feedback group(group I and II) and the normal learning group(groupIII)(p>.05).

The purpose of this study was to investigate the kinematic parameters between a stalled group and a less skilled group of female javelin throwers, in order to record differences in their support landing and release phase. For this, the female athletes were divided into two groups: the sidled group, which consisted of javelin throwers with records over 45m, and the less skilled group, which consisted of javelin throwers with records below 45m. During the release phase, the horizontal velocity differed significantly(p<.05) between the two groups. The projection angle at the release moment also differed significantly(p<05) between the groups. The knee angle of the support leg differed significantly(p<.05) between the two groups at E1, E2, and E3, but there was no difference at E4. The shoulder angle differed significantly(p<.05) between the two groups only during the landing of the power leg.

The Purpose of this study was to examine the effects of boxing aerobic training on resting heart rate variability (HRV) in females. The subjects for this study were performed 16 female college students that aged 19-23. The subjects were divided into two groups; boxing aerobic exercise group (9 students) and control group (7 students). Boxing aerobic training program was performed three times a week for twelve weeks with $VO_{2max}$ 60-80% exercise intensity. The results of this study were following; 1. Mean HRT (mean heart rate) had no signigicant difference among the groups and exercise time. 2. SDNN (standard deviation of the normal to normal interval) had no significant difference among the group and exercise time. 3. RMS-SD (square root of the mean squared differences of successive normal to normal interval) had no significant difference among the groups and exercise time. 4. TP (total power) had no significant difference among the groups and exercise time. 5. LF (low frequency) had no significant difference among the groups and exercise time. 6. HF (high frequency) had no significant difference among the groups and exercise time. 7. LF/HF (low frequence/high frequency ratio) had no significant difference among the groups and exercise time. 8. VLF (very low frequency) had no significant difference among the groups and exercise time.

The purpose of this study is to fine out whether melodic percussion playing group program affects the team cohesion and team efficacy of youth soccer players. In this study fifty seven middle school soccer players were participated. The participants were assigned to either a melodic percussion playing group or a control group. In order to identify the effectiveness of music program, assessments were conducted using the team cohesion and team efficacy scales before and after the program. The results of comparison analysis through t-test are as follows. First, in the posttest of team cohesion between groups, the experimental group showed a significant difference over the control group. In the pretest and posttest examinations within a experimental group, the group also showed a significant difference. Second, in the posttest of team efficacy between groups, the experimental group showed a significant difference over the control group. In the pretest and posttest examinations within a experimental group, the group also showed a significant difference. These results of this study suggest that melodic percussion playing group program may be an effective intervention tool to improve team cohesion and team efficacy of youth soccer players.

한국 고유종인 새코미꾸리(Cobitis rotundicaudata)의 집단간 유전적 차이에 따른 종 분화 여부를 밝히고자 4개집단을 대상으로mitochondrial DNA(mtDNA)의 RFLP분석을 실시 하였다. C. rotundicaudata mtDNA를 10개의 6-base cutting 제한요소로 처리한 다음 그 절 편 양상을 비교, 분석한 결과 4개 집단 공히 mtDNA의 전체 genome 크기는 약 16.5$\pm$ 0.5Kbp였으며 공통절편수(F)에서 한강 2개 집단(가평, 진부)과 동해안 마읍천 짐단간의 F값 은 0.911로 매우 가까웠으나 낙동강의 산청집단은 타 3개 집단과 F=0.375로 차이가 있었다. 또한 염기치환율(p)에 있어서도 한강 2개 집단 및 마읍천 집단간은 평균 p=0.005로 매우 유 사하였으나, 산청 집단은 타 집단들과 염기치환율에 있어 p=0.059로 종수준의 뚜렷한 차이 를 나타내어서 이들은 각각 별종으로 사료된다.

This study focused on science activities that need collaborative inquiry process and evaluate the effects of small group's science cooperative learning according to personality types on young children's science activities. The subjects are 30 five-year-old kindergarteners. They have been divided equally into three groups, extroversion(E), interversion(I), and heterogeneous group of EI mixed group depending on EI indicators through K-ABC cognitive ability tests and MMTIC personality types targeting. Both of groups have 10 members each. For data analysis, scientific attitude was analyzed with ANCOVA, scientific knowledge development was done with frequency analysis. As a result, first there was a difference in scientific knowledge development between the homogeneous group and heterogeneity group in small group's cooperative learning. Through the results of a Scheffe post-hoc test, there was a significant difference between E and I homogeneous groups but there was no difference between I homogeneous group and the heterogeneity group, and between E homogeneous group and the heterogeneity group, I homogeneous group had the most effective group composition in scientific attitude improvement.

This study aimed to investigate the differential effects of individual's cultural disposition (individualism-collectivism or horizontal-vertical thinking) and need for cognitive closure(NFC) on framing effects. For this purpose, the participants were divided into 4 different cultural disposition groups based on Singelis et al.'s[1] INDCOL scale, and 2 different NFC groups based on Lee's[2] NFC Scale, and then asked to respond on 5 decision making scenarios. The results can be summarized as followings. First, participants preferred risk-avoidant option in gain frame, whereas risk-seeking option in loss frame. Second, there are no difference of cultural disposition on framing effects, but high NFC group showed larger framing effects than low NFC group in loss frame. Third, collectivism and vertical thinking in high NFC condition showed larger framing effects than low NFC condition.

한국산 도룡농, Hvnobius leechii의 7개 집단에서 mitochondrial DNA(mtDNA)의 변이가 조사되었다. MtDNA의 크기에서의 차이는 관찰되지 않았으나 제한효소 인식 부위에서의 차이가 조사되었다. MtDNA의 절편 양상은 각 집단에서 동일하게 나타났다. 제한 효소로 처리하여 얻어진 절편의 비교에서 종내 변이는 염기 치환에 의하여 발생한 것임이 분석되어졌다. 특히 하동과 제주 집단은 몇개의 제한 효소 인식 위치에서 나머지 5개 집단과 뚜렷한 차이를 보였다. 염기치환율(p값)은 공통 절편 비율(p값)을 토대로 하여 얻어졌으며 그 값은 0.004에서 0.064의 범위 내의 값으로 측정되었다. 하동과 제주 집단을 제외한 5개 집단의 비교에서는 비교적 낮은 침의 염기 치환율을 보였으나 제주와 나머지 집단들과의 비교에서는 염기치환율이 높게 측정되었다. 염기 치환율과 관련지어 염기 분화 연대를 측정한 결과 도룡뇽 7개 집단은 3개의 group으로 나뉘어 졌으며 이들은 약 188만년전에 분화된 것으로 사료되어 진다.
