본 연구는 청소년 볼링 선수들의 경기 대처 기술 요인의 구조를 밝히는 것으로 이를 바탕으로 볼링선수들의 성공적인 수행을 예상하여 경기력을 향상 시키는데 그 목적이 있다. 이러한 연구목적에 맞추어 본 연구는 우수선수와 비 우수선수의 심리적 기술 요인을 측정하기 위하여 Smith, Schutz, Smoll, Ptacek(1995)에 의해 개발된 선수들의 대처기술(ACSI-25: the Athletic Coping Skills Inventory-28)척도를 국내 실정에 맞게 번안하여 심리측정적 타당도를 검증한 후 사용하였다. 각 요인별 타당도와 신뢰도를 화보하기 위하여 요인분석을 실시한 결과 16문항 6요인으로 분류되었으며, 분류된 6개의 심리기술 요인을 성취욕구, 걱정, 코칭능력, 목표설정, 역경대처, 집중력으로 명명하였다. 이 후 각각의 배경변인(성별, 우수여부, 학년)에 따른 각 요인별로 three-way MANOVA분석 결과 6개 요인에 대한 배경변인의 차이는 발견되지 않았다. This study aims to provide information on how to improve bowlers capacity by examining amateur bowlers athletic coping skill factors. A test paper on the Athletic Coping Skills Inventory-28(ACSI-28) developed by Smith, Schutz, Smoll, and Ptacek(1995) is used in order to measure the athletic coping skill factors of excellent as well as mediocre players. This paper is adapted for the domestic situation, with its appropriateness for measuring the bowlers mental state verified. Crombach's α result is used in classifying 16 questions and 6 factors, with factor analysis done in order to secure the appropriateness and credibility by each factor The six factors are: accomplishment desire, worry, coaching ability, goal setting, coping with adversity, and concentration, A statistic analysis is then conducted according to environmental variables such as sex, excellence, and grade. Based on the analysis, the following conclusions are derived: The factor analysis reveals six athletic coping skill factors of bowlers, e,g,, accomplishment desire, worry, coaching ability, goal setting, coping with adversity, and concentration. A three-way MANOVA analysis per three environment variables (sex, grades, and excellency) for the six athletic coping skill factors (accomplishment desire, worry, coaching ability, goal setting, coping with adversity, and concentration) reveals that environment variables do not cause any difference in the psychological technique factors of bowlers. In order to verify the effect of a bowlers maturity on the six athletic coping skill factors (accomplishment desire, worry, coaching ability, goal setting coping with adversity, and concentration), multiple regression analysis is done with a multi-step method, using predicative variables and athletic coping skill factors as reference variables. The result shows that the bowlers level of maturity is evident in goal setting and coping with adversity.

이정애,홍승호 韓國敎員大學校 敎育硏究院 2009 敎員敎育 Vol.25 No.3

본 연구는 일반학급 400명과 영재학급 155명의 학생들을 대상으로 초등학교 과학과 생명영역의 '곤충’에 관한 개념의 인식 및 오개념 형성 원인을 비교하였다. 이를 위해 초등과학의 '곤충’과 관련된 단원에서 '곤충’에 대한 개념을 추출하여 타당도 검사를 거친 후 퍼개 문항을 선정하였으며,개념 검사지를 총 555명에게 투입하였다. 설문 조사 결과,18개 문항 중 11개 문항에서 일반학급 학생들이 영재학급보다 유의하게 높은 오답율을 나타냈다. 일반학급 학생들의 '곤충’ 개념에 대한 오인 요인으로는 주로 잘못된 유추로 인한 성급한 일반화와 직관적 사고 등에 의한 것으로 나타났다. 성별 간 오답율 비교에서는 '곤충’의 정의에 관한 2개 문항,몸 구조에 관한 2개 문항,한살이에 관한 1개 문항,생활에 관한 3개 문항에서 여학생들이 남학생들보다 유의하게 높았다. 이에 대한 원인으로는 여학생들이 '곤충’을 징그러워하거나 무서워하는 경향이 높아 그와 관련된 개념 습득에도 어려움이 있는 것으로 생각된다. 학년 간 비교에서는 '곤충,의 정의에 관한 1개 문항,몸 구조에 관한 1개 문항,한살이에 관한 2개 문항에서 5학년 학생들이 6학년 학생들보다 오답율이 유의하게 높았다. 이는 6학년 과정에서 동물의 분류에 대한 내용을 학습하기 때문에 학습 경험이 많은 6학년이 '곤충’에 대한 개념을 잘 알고 있었다. 따라서 학교현장에서는 '곤충’에 대한 오개념 교정을 위하여 인지갈등을 유발할 수 있도록 다양한 교수-학습 자료를 개발하여야 할 것이다. The purpose of this study is to provide tine basic data for misconception correction on 'insect'. The study subjects are composed of 400 average and 155 gifted-in-science elementary school students. The major results are as follows: a degree of the scientific concepts of the gifted students was much higher than that of the average students, especially in 11 items. The reasons of the wrong answers are classified into hasty generalizations by wrong deduction and intuitive idea. On the other hand, the proportion of wrong answers of female students was higher than that of male students, especially in 8 items. As the possible explanation for the difference, female students may dislike and creepy on 'insects' compared to male students. Another possibility is that the difference may be appeared due to the lack of experience on 'insects' in nature. The proportion of the scientific concepts of the 6th grade students was higher than that of the 5th grade students, especially in 4 items, suggesting that there were differences in learning experience. To correct the misconceptions on 'insects', therefore, it is necessary to develop various teaching-learning materials to induce the cognition conflicts.

초등학생들의 곤충에 대한 개념 인지도 및 오개념 형성 원인 분석

이정애,홍승호 이화여자대학교 교과교육연구소 2008 교과교육학연구 Vol.12 No.3

본 연구는 초등학교 과학과 생명영역의 ‘곤충’에 관한 초등학생들의 개념 인지도와 오개념 형성원인을 조사하였다. 이를 위해 ‘곤충’과 관련된 단원에서 개념을 추출하여 검사 도구로 이용하였으며, 설문 조사는 초등학교 5~6학년 400명을 대상으로 이루어졌다. 설문 조사 결과 18개 문항 중6개 문항에서 40% 이상의 높은 오답율을 보였다. 이러한 곤충의 오개념에 대한 형성 요인으로는 내적 요인 중 미숙한 인지발달, 성급한 일반화, 잘못된 유추 과정, 직관적 사고 등에 의한 것으로 볼 수 있으며, 외적 요인으로는 자연현상에 대한 경험이나 문화적 경험의 부족, 언어의 모호성, 교과서 등 복합적으로 작용하여 형성된 것으로 판단된다. 성별 간 개념의 인지도는 여학생들이 남학생들에 비해 오답율이 높게 나타났다. 그 까닭은 대다수의 여학생들이 남학생들보다 곤충을 징그러워하거나 무서워하는 경향이 높아 그와 관련된 개념 습득에도 어려움이 있는 것으로 해석된다. 도시학생과 농촌학생 간의 답변 빈도에 있어서는 5개의 문항에서 유의한 차이가 있었으며, 곤충에 대한 지식을 도시학생들은 주로 서적, 농촌학생들은 주로 생활 주변의 경험을 통해서 얻고 있음을 알 수 있었다. 최근의 우리 생활이 서구화가 급속도로 이루어진 만큼 도시나 인터넷 문화에 적응되면서 자연환경에서의 학습이 과거보다 덜 이루어지고 있는 것이 사실이다. 따라서 ‘곤충’에 대한 오개념을 교정하기 위해서는 현장학습을 통하여 실제의 관찰이 무엇보다도 필요하다고 보며,교실에서도 올바른 과학적 개념 정립을 위하여 구성주의나 개념변화 학습모형 등을 적용하여 학생들에게 적절한 갈등유발을 유도할 수 있도록 힘써야 할 것이다. The purposes of this study were to investigate the misconception proportion and the reasons on 'insects' in the elementary school students. The study subjects were composed of 400 average students of urban and rural in Jeju province. A questionnaire was made of 18 test questions for examination of concepts in 'insects'. The data obtained in this study were analyzed by SPSS statistical program. The major results were as follows: The cognitive proportion on 'insects' was low, especially in 6 questions. The reasons of the misconceptions in this study were classified into an immature cognitive factors, a misapprehension of consciousness, hasty decision and deduction, the wrong analogical inference, mass communications (TV or internet), experimental difference in nature and culture, vagueness of the language, and textbook. On the other hand, the misconception proportion of female students was higher than that of male students in 6 questions. As the possible explanation for the difference of the misconception proportion, female students are due to dislike and creepy on 'insects' compared to male students. Another possibility is that these differences can be influenced by the difference of experiment in nature on 'insects'. In comparison of concepts between rural and urban students, there were similar to each other. To correct the misconceptions on 'insects', therefore, it needs to do inquiry activities, explanation of various examples, discussion activities through small groups, induction of complications for conceptual change learning, and so on. Data from this study may help teachers carrying out education for elementary students to reconsider their conceptions on 'insects'.

This study was performed to provide the basic data for preservation and improvement of genetic resources according to finding genetic construction obtained from analysis of genetic characteristics of β-casein gene in Korean Native goat and Saanen using the PCR-RFLP. This study confirmed the amplified products of 481bp fragments obtained from the amplification of β-casein loci by PCR. The β-casein AB genotype showed 481, 284 and 197bp, and β-casein BB genotype showed 284 and 197bp fragments in Korean Native goat and Saanen. The frequencies of β-casein genotype in Korean Native goat were 6.25 and 93.75% for AA and AB and the frequencies of β-casein genotype in Saanen were 57.14 and 42.86% for AA and AB types. The frequencies of β-casein A and B alleles were 0.031 and 0.969 in Korean Native goat and the frequencies of β-casein A and B alleles are 0.286 and 0.714 in Saanen, respectively. The nucleotide sequence of β-casein gene of Korean Native goat was 97.71% higher homology with 11 nucleotide sequences difference of that of goat reported in GeneBank (M90556). Therefore, this study of molecular genetic characteristics by the analysis of genetic polymorphism and sequencing for β-casein gene should be used as basic and applying data for preservation and improvement of genetic resources in Korean Native goat breeding.

마약길항제의 방출 제어형 제제 (제1보) : 생체분해성 polyphosphazenes의 합성과 나록손 이식제제의 제조 및 용출특성 Synthesis of Biodegradable Polyphosphazenes and Preparation and Release Characteristics of Naloxone Implant

For the administration of narcotic antagonist with short half-life and low patient compliance. the sustained release system using biodegradable matrix is effective. Polyphosphazenes are of considerable interest as biodegradable matrix systems for controlled release of drugs. In this study. biodegradable polyphosphazenes available for the sustained release implantable device were synthesized. and their application was examined. Poly〔dichlorophosphazene〕 was synthesized by solution polymerization method and confirmed with IR spectrum. Poly〔bis(ethyl glycinate) phosphazene〕 and poly[(diethyl glutamate)-co-(ethyl glycinate)phosphazene] were then produced by substitution of amino acid alkyl esters for chloride side groups. Using these polymers. the implantable devices of 1 ㎜ thickness and l0 × 10 ㎜ size containing naloxone hydrochloride were prepared and their release and degradation profiles were measured. In the case of poly〔bis(ethyl glycinate)phosphazene〕 with swelling characteristics, degradation rate was slower than the release rate, showing that the release rate is partly dependent on the swelling rate. In contrast, the degradation rate of poly〔(diethyl glutamate)-co-(ethyl glycinate)phos-phazene〕 matrix was identical with release rate of naloxone hydrochloride. On the basis of these results, it is expected that these polymers can be applied to sustained release implantable systems delivering narcotic antagonist.

변은정,박주애,이승진,김길수 梨花女子大學校 藥學硏究所 1998 藥學硏究論文集 Vol.- No.7

Poloxamer-poly(acrylic acid)(PAA) interpenetrating polymer networks (IPNs) were prepared via matrix polymerization of acrylic acid with poloxamer prepolymer. The equilibrium swelling of poloxamer/PAA IPNs was determined in various pH medium. The swelling of poloxamer/PAA IPNs was more affected by pH difference compared with the swelling of homo PAA gel due to protonation and deprotonation of the PAA network. followed by reversible formation and dissociation of the interpolymer complex due to hydrogen bonding between acidic hydrogens and ether oxygens. Nonionic/anionic/cationic drugs were incorporated into IPN matrices as a model drug and their release behavior was studied. Nonionic drug revealed release patterns depending solely on pH dependent swelling kinetics. In contrast, the release of ionic drugs was significantly affected by ionic drug-polymer interaction as well as the swelling kinetics.

Objectives : The aims of this study were to identify the intake and following process for subjects at high risk of transition to schizophrenia and to examine the neurocognitive, social, and emotional functions of the subjects compared with healthy controls. Methods : Symptomatic individuals judged at high risk for schizophrenia ('clinical high risk') within Youth Clinic were assessed and followed up. They performed a neurocognitive function test, a social function test and an affective function test. Twenty healthy controls were recruited in this study. Results : Among eighty-two subjects contacted through the Youth clinic, sixteen subjects were judged as the clinical high risk group. Fourteen subjects among the clinical high risk group showed deficits in several domains of neurocognitive functions, such as visual recall memory, verbal short term memory and executive function. Social and affective functions are also impaired in the Cli-nical high risk group compared with healthy controls. Two of 15 subjects (13%) developed a psychotic disorder within 6 months. Conclusion : This study illustrates the state of follow-up study for a clinical high risk group. Despite low numbers and short durations, some impairment of several functions in the clinical high risk group suggests possible predictors of psychosis.
