본 연구의 목적은 초등학생용 및 중·고등학생용‘KEDI 창의적 인성검사(Creative Personality Scale)’를 개발하고 그 타당성을 검증하기 위한 것이다. 본 연구에서 검증한‘KEDI 창의적 인성검사’는 종래에 논의되어 온 다양한 창의적 인성이론들을 검토하고, 기존의 창의적 인성검사들의 장단점을 활용 및 보완하여, 초ㆍ중고생들의 발달적 특성을 고려한 문항으로 차별화시켜 개발한 검사라는 점에서 의의가 있다. 본 연구에서는 선행 연구 및 기 개발된 창의적 인성검사의 분석을 토대로 새롭게 개발한‘KEDI 창의적 인성검사’의 신뢰도와 타당도를 검증하되, 내적일치도, 구인타당도, 변별 및 수렴타당도, 준거타당도의 측면에서 분석했다. 내적일치도는 초등학생용의 경우 .60이상으로 비교적 양호하게 나타났고, 중ㆍ고등학생용의 경우 판단의 독자성과 사고의 개방성을 제외한 나머지 요인들이 .60 이상으로 비교적 양호하게 나타났다. 확인적 요인분석을 통한 구인타당도 결과는 초등학생용의 경우 주요 적합도지수인 RMSEA(.050), CFI(.904), TLI(.883), IFI(.905)에서 적합한 것으로 나타났다. 또한 중ㆍ고등학생용의 경우 RMSEA(.050), CFI(.838), TLI(.801), IFI(.840)에서 적합한 것으로 나타났다. 또한 하주현의 창의적 인성검사(2000)와의 상관을 통한 준거 타당도 결과도 초등학생용의 경우 .809(P<.01)로 높았고, 중ㆍ고등학생용의 경우 .731(P<.01)로 높게 나와 적합한 것으로 밝혀졌다. The purpose of this study is to verify the validity of KEDI Creative Personality Scale for elementary and secondary school student. The existing creative personality scales(CPS) is outdated by excessive or insufficient items, focused on several limited abilities for adult. But this verified KEDI CPS is not only included comprehensively what have been argued and developed for 10 years about creative personality, but also is differentiated by developmental characteristics of elementary and secondary school student To verify reliability and validity of this KEDI CPS, we analyze internal consistency of scale for reliability and construct validity, convergent and discriminative validity. criterion-related validity. The internal consistency of the scale for elementary school student is relatively higher than .60, and all the factors except ‘the independent decision making’ and ‘the openness of thought’ are relatively higher than .60. The confirmatory factor analysis using AMOS to verify construct validity revealed that the structural equation model including 6 construct validity in KEDI CPS showed fit index at a satisfactory level as follows. The major fit indexes are showed as follows; RMSEA(.05), CFI(.904), TLI(.883), IFI(.905) in the scale for elementary school student, RMSEA(.050), CFI(.838), TLI(.801), IFI(.840) in the scale for secondary school student. Futhermore, to secure criterion-related validity, this KEDI CPS showed highly significant correlations with Hah’s Creative Personality Scale elemantary for r=.809(p<.01), secondary for r=.731(p<.01)).

포유동물에서 뇌와 부신에서 합성·분비되는 카테콜아민(Catecholamine, CA)계 신경전달물질인 dopamine(DA), norepinephrine(NE), epinephrine(E)은 체내 각종 생리현상의 조절에 필수적이며, 생식과 관련된 기능으로는 시상하부와 뇌하수체 사이의 GnRH-gonadotropin 호르몬 축의 활성을 조절함 외에도 번식과 연관된 여러 행동양식을 조절함이 잘 알려져 있다. 본 연구는 카테콜아민 생합성 효소인 tyrosin Dopamine(DA), norepinephrine(NE), and epinephrine(E) belong to a class of neurotransmitters known as catecholamine (CA) which are synthesized and secreted by mammalian brain and adrenal medulla. CA regulate several behavior patterns connected with breeding, and regulate GnRH-gonadotropin hormone axis' vitality between hypothalamus-pituitary gland linking with reproduction freeze. The present study examined effects of sex steroid hormone on the transcriptional activities of CA biosynthesis enzymes, tyrosine hydroxylase(TH), dopamine -hydroxylase(DBH), and phenylethaolamine-N-methyl transferase(PNMT). Mature female rats were ovariectomized(OVX) and implanted with 17 -estradiol(E: 500 /ml) or sesame oil. Forty-eight hours after implantation all the animals were sacrificed. Total RNAs were extracted immediately and were applied to semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR). The expression level of TH was appeared by hypothalamus > SNc> adrenal medulla orders in OVX+Oil group, and by SNc > hypothalamus) adrenal medulla orders in OVX+E group. Treatment with E significantly increased TH expression in SNc and adrenal medulla but in hypothalamus, the reduced TH expression was observed. The expression level of DBH was appeared by adrenal medulla > SNc > hypothalamus orders in OVX+Oil group and in OVX+E group. Administration of E significantly reduced DBH expression in SNc, and increased in adrenal medulla. Two cDNA products, large(PNMT1) and small(PMNTs) species of 110bp difference, were amplified in SNc and hypothalamus, but only PNMTs was observed in adenal medulla. The PNMTs expression level was in the order of adrenal medulla > hypothalamus > SNc in both OVX+Oil and OVX+E group. The PNMTs expression in SNc and adrenal medulla was significantly increased byE. The present report demonstrated that estrogen effects on transcriptional activities for CA biosynthethic enzymes were tissue specific in adrenal medulla as well as different region of brain. These results suggest that it might be crucial relationship between the type of estrogen receptor and CA enzyme gene expression.
