The study examined the effects of parenting process(supportive and involving mother-adolescent relationship, father-adolescent relationship) and school process(teachers' support, school life satisfaction) on adolescents' academic achievement and self-evaluation. Participants were 1787 middle school students (902 boys, 885 girls) in KEEP(Korean Education and Employment Panel). Structural equation modeling indicated that parenting and school process influenced adolescents' self-evaluation through adolescents' academic achievement. Also, the analysis with One Way ANOVA revealed that positive school (parenting) processes can serve a protective-stabilizing function when parenting(school) processes are negative.

중학교의 함수 개념 도입과 관련하여 7차 교육과정의 개정 시 종속적인 변화관계에 기반하여 도입하도록 큰 변화를 시도하였고 이러한 방향은 현재 2009 개정 교육과정에서도 유지되고 있다. 이에 본 연구에서는 이러한 교육과정의 변화가 학생들의 함수개념 이해에 어떤 변화를 가져왔는지 그리고 실제 교수 학습 장면에서 함수가 어떻게 지도되고 있는지를 탐색하였다. 이를 위해 학생들의 경우 과제기반 심층 면담을 통해 함수 개념화의 특성을 살펴보았고 또 다른 한편으로는 학생들의 지도교사들을 대상으로 면담을 실시하여 수업에서 함수를 도입하는 방식에 대해 질문하였다. 연구결과 학생들은 종속적 변화관계에 기반하여 함수를 인식하는 정도가 매우 미약하며 교사들 또한 종속적 변화관계에 기반하여 함수를 지도하는데 어려움을 겪고 있음을 확인할 수 있었다. 이러한 논의를 바탕으로 학교수학에서 함수 지도와 관련한 몇 가지 제언을 하였다.

A class of functions involving divided differences of the psi and tri-gamma functions and originating from Kershaw's double inequality are proved to be completely monotonic. As applications of these results, the monotonicity and convexity of a function involving the ratio of two gamma functions and originating from the establishment of the best upper and lower bounds in Kershaw's double inequality are derived, two sharp double inequalities involving ratios of double factorials are recovered, the probability integral or error function is estimated, a double inequality for ratio of the volumes of the unit balls in $\mathbb{R}^{n-1}$ and $\mathbb{R}^n$ respectively is deduced, and a symmetrical upper and lower bounds for the gamma function in terms of the psi function is generalized.

This is a survey in order to provide basic information for smoking cessation teaching as investigate adolescent smoking, stress, family function and vital power. Data collection was done at the high school(12 class) and middle school(12 class) with quota sampling during 2 weeks from October 27, 2000. in the metropolitan area of Taegu. Total subjects of this study were 1710 students. The instruments for this study were the Life Event Checklist, Family APGAR, and vital power item among in the SF-36. Frequency, percentage, t-test, ANOVA, and multiple logistic regression by SPSS/PC Win Ver7.5 program were used to analyze the data. The results of this study were as fellows; 1) The subjects of this study was consisted with middle school student (876, 51.2%) and high school students. The students that they have used smoking at past or current smoker was reported 18.9%. Most of the smoking adolescents reported that they started smoking during middle school age, and there were more smoking rate among vocational high school students than academic high school students. 2) There were more stress among high school, men, and vocational high school. In aspect of family function, there were reported high score among women and middle school. At the vital power, there were reported more score among men students than women students. 3) Current smokers were more likely than nonsmokers to report more stress, low family functioning. 4) In order to identify predicting factor for adolescent smoking, family function and stress were tested significant variables statistically.

Purpose : The purpose of this study was to investigate the effects of a virtual reality-based occupational therapy program on the physical function and learning ability of intellectually disabled school-aged children. Methods : In this study, 20 intellectually disabled children of school age were randomly and evenly divided into experimental and control groups with children in the experimental group receiving a virtual reality-based occupational therapy intervention. The study adopted a pretest-posttest design. The intervention was conducted for a total of 12 sessions for six weeks, twice a week, and 50 minutes per session. As measurement tools, BOT-2 and grooved pegboard tests were used to compare physical function before and after the intervention program, and K-ABC was used to check changes in learning ability. Results : The occupational therapy program produced a significant improvement in both physical function and learning ability of the experimental group. A significant difference was observed between the experimental and control groups. Conclusion : This study confirmed the value and usefulness of virtual reality-based occupational therapy as a tool for enhancing the physical function and learning ability of intellectually disabled school-aged children. Based on the results, a variety of future studies are encouraged that would further test the effects of the occupational therapy program used here.

The present study examined the 7th national elementary school mathematics curriculum from a perspective of mathematical creativity. The study investigated to what extent the activities in the Pattern and Function lessons in the national elementary school mathematics textbooks promoted the development of mathematical creativity. The results indicated that the current elementary school mathematics curriculum was limited in many ways to promote the development of mathematical creativity. Regarding the activities in Pattern lessons, for example, most activities presented closed tasks involving finding and extending patterns. The lesson provided little opportunities to explore the relationships among various patterns, apply patterns to different situations, or create ones own patterns. In regard to the Function lessons, the majority of activities were about computing the rate. This showed that the function was taught from an operational perspective, not a relational perspective. It was unlikely that students would develop the basic understanding of function through the activities involving the computing the rate. Further, the lessons had students use exclusively the numbers in representing the function. Students were provided little opportunities to use various representation methods involving pictures or graphs, explore the strengths and limitations of various representation methods, or to choose more effective representation methods in particular contexts. In conclusion, the lesson activities in the current elementary school mathematics textbooks were unlikely to promote the development of mathematical creativity.

To probe the chemical constituents of Patrinia scabra, we undertook the phytochemical investigation on its roots, which led to the isolation and elucidation of three new iridoid glucosides, scabroside A-C (1-3), along with three known iridoids, jatamanin J (4), isopatriscabroside I (5) and loganic acid (6) from the aqueous fraction of the ethanolic extract of the roots. The structures and relative configurations of the three new compounds were elucidated by spectroscopic methods including IR, UV, MS, 1D and 2D NMR experiments. Compound 3 was an unusual iridoid with an oxygen bridge connecting C-3 and C-8.

본 연구에서는 이차함수, 유리함수, 무리함수, 지수함수, 로그함수, 삼각함수와 같이 고등학교 수학 교육과정에서 이미 배운 기본적인 함수들의 모양 그리기와 해석하는 능력을 분석하였다. 00 고등학교의 인문반 2개반(64명)과 자연반 2개반(64명)을 대상으로 조사한 결과 주어 진 함수들의 모양을 그리지 못한 학생이 50% 이상이었다. 또한 함수가 지닌 중요한 성질인 정의역, 치역, 최솟값, 최댓값, 주기 등에 대한 해석하는 능력이 부족한 것으로 나타났다. 본 연구에서는 함수단원이 고등학교 수학이나 대학 교양 수학에서 기초가 되는 내용이므로 함수의 개념과 함수의 모양 그리기, 함수의 모양 오류 데이터 분석 등의 수학학습에 관하여 연구하였다.

Purpose: This study was done to determine the effects of a neurofeedback program on brain function and stress in occupational high school students. Method: A nonequivalent control group, non-synchronized with pre-posttest design was used with 62 students. Data collection was done from July to December, 2007. The neurofeedback training was given for 30 minutes at a time, three times a week for 12 weeks. Brain function was measured by brain waves in the frontal lobes of the students and analyzed by eight brain quotients characterizing patterns of EEG rhythms. The instrument used to measure stress was a scale for stress from regular daily life. Results: After neurofeedback training, the level of brain quotients in students in the experiment group increased(t=2.36, p<.05) and the level of stress decreased(t=-3.59, p<.001). Conclusion: The results of the study suggested that a neurofeedback program is effective for brain function improvement and stress reduction in high school students. Therefore, the conclusion of this study is that neurofeedback programs can be useful to increase brain function and decrease stress in occupational high school students.
