Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

This study was designed to investigate the effects of the posterior slope of the articular eminence and the condylar angulation to the posterior slope of the articular eminence on internal derangement of TMJ. The materials consisted of 78 transcranial oblique lateral projections of 31 normal subjects and 47 interal derangement patients. The reults were as follows: 1. The posterior slope of the articular eminences in normal group were large than that in abnormal group, but there were not significant differences between each group about the condylar angulation to the posterior slope of the articular eminences. 2. The differences between in the right and left sides in patients who were affected unilaterally and bilaterally were larger than that in normal groups. 3. In patients affected unilaterally, there were not significant differences between affected joints and unaffected joints about the posterior slope of the articular eminence and the condylar angulation to the posterior slope of the articular eminence. 4. In abnormal group, there were significant differences between each group about condylar angulation to the post, slope of the articular emienece (ant. disk displacement without reduction>fibrous adhesion>ant. disk displacement with reduction), but not about the post, alope of the articular eminence.

친족체계의 실천적 이해 : 요루바 친족 출계율을 중심으로

한건수 서울대학교 사회과학연구원 2000 비교문화연구 Vol.6 No.2

Yoruba kinship system has been discussed in the legalistic tradition of kinship studies.It has mainly focused on the descent rule of Yoruba kinship system.This legalistic tradition leads Yoruba specialists to consider the reason for the presence of diverse Yoruba kinship system as the result of different descent rules (agnatic or cognatic) regulating each kinship organization.The classification between the northern (agnatic system) and southern (cognatic system) Yoruba groups, produced by the legalistic studies, however, is unable to explain the real meaning and the dynamics of kinship relations in everyday life.This paper argues that it is necessary to change analytic paradigm from structure to practice in order to consider Yoruba kinship system not only as the structural principle but also as the cultural practice of human agent. This paper suggests analyzing Yoruba kinship beyond the kinship norms, and explaining the way how multiple principles of kinship system interact, and how the kinship ideology is interpreted arid negotiated in practice.In this purpose, this paper first analyzes interaction process of two contesting structural principles of Yoruba kinship: solidarity of "o.mo.i`ya´" (children of same mother) and patrilineal descent rule.Through this analysis, this paper shows the importance of both mother-child bond and matrilateral relations in Yoruba kinship, which are considered as secondary or emotional one in the traditional Yoruba kinship studies.Second, this paper also emphasizes the need to consider the different variations of Yoruba kinship system as the result of historical processes.With the concept of "practical kinship," this paper illustrates how an O.lo´.gbe´.n´la´ lineage group has been reproduced as the response to political and economic factors of O`ke`-Igbo´ town.In sum, this article shows the necessity and feasibility of new perspective, an approach which focuses on the actors of kinship practice and analyzes how official kinship is reproduced through practical kinship in historical processes.

This study was intended to investigate the changes of general bacteria, psychrotropic bacteria and coliform group for revealing the variation of quality in frozen chickens. Beforehand the chickens were classified frozen for 60 days in 4 groups, that is, controlled group(T1), packaged group(T2), glazed group(T3) and cured group(T4). And then these samples were thawed and used for this study. Bacterial counts of general bacteria in group T1 much more rapidly decreased(49.4%) than that in group T4 and the decreasing rate was significantly high at 30 days afterward. Decreasing rate in cells of psychrotropic bacteria showed minimum in group T1 (49.9%) and maximum in group T4 (77%). Similarly decreasing rate in coliform group counts were higher in group T4 (82%) and lower in group T1 (62%) compared to that in any other group and particularly decreased at 15 days afterward.

명건식,임윤수,최종환 충남대학교 경상대학부설 경영경제연구소 1999 경영논집 Vol.15 No.1

최근 금융의 자유화는 금융자산의 시장변동성을 심화시키며 대형금융사고를 야기 시키고 있다. 이에 규제기관 및 시장참여자들은 주가, 금리, 환율, 상품가격 등 시장 경제 변수의 변동위험 즉, 시장위험(market risk)관리의 중요성을 재차 인식하게 되었다. 본 논문은 금융자산의 시장위험을 측정, 관리할 수 있는 내부모델로서 KOSPI 200 선물지수를 대상으로 역사적 시뮬레이션 접근법(historical simulations), 분산-공분산 접근법(variance-covariance method), 몬테카를로 접근법(Monte Carlo simulations)을 통한 VaR의 계산과 실제거래위험과의 차이를 비교, 검토함으로써 위험관리 방법으로서의 사후적 효과성을 검증하고자 하였다. 이를 위해 1996년 5월 3일부터 1998년 9월 10일까지의 KOSPI 200 선물지수의 최근월물 만기 3개월 일별 종가를 대상으로 보유기간은 1일, 신뢰수준은 95%와 99% 그리고 Position은 전일 종가를 기준으로 매수와 매도를 가정하여 손익을 계산하였다. 본 연구결과 시장위험의 관리수단인 VaR인 KOSPI 200 선물지수의 위험관리수단으로서 95%와 99%의 신뢰수준 하에서 상기의 방법으로 측정한 결과 BIS에서 제시하는 모델의 정확성 영역구분에서 황색 또는 적색영역에 해당되는 결과를 보이고 있다. 이는 위험관리 수단으로서 VaR기법의 남용은 이에 관한 통일적 방법이나 기준이 제시되고 있지 않은 국내의 상황에서 정확성이 검증되지 않은 방법으로 시장위험을 관리하는 즉, 또 다른 위험을 야기할 수 있는 가능성을 내포하고 있음을 암시하고 있다.

김건영,고용권,배대석,김천수 한국광물학회 2004 광물과 암석 (J.Miner.Soc.Korea) Vol.17 No.1

방사성폐기물의 처분연구와 관련하여 대전 유성지역 화강암내 심부 시추공 시추코아의 단열 광물들에 대한 광물학적 특성을 연구하였다. 유성지역의 심부시추공들에는 다수의 단열대가 발달해 있으며 국지적인 열수변질작용이 중첩되어 있다. YS-01 시추코아에 대한 전암분석결과 -90 m ∼-130 m 구간과 -230 m∼-250 m 구간에서 급격한 SiO₂ 함량 감소와 Al₂O₃, CaO, L.O.I 값의 증가가 관찰되며 이는 단열충전광물의 생성과 관련이 있다. 이러한 단열충전광물에 대한 XRD분석결과 불석광물(로몬타 휼란다이트), 방해석, 일라이트(2M₁1M_(d) 다형), 녹니석, 녹염석, 카올리나이트 등이 확인되었으며, 산출되되는 양은 방해석 불석광물 > 일라이트 > 녹염석 >> 녹니석 > 카올리나이트의 순이다. SEM관찰 및 EPMA 분석결과, 단열충전광물들의 심도에 따른 조직 및 화학특성 변화는 관찰되지 않는다. 연구지역은 화강암반내에 발달된 단열재가 지하수의 유동로로 작용하여 오랜 기간에 걸친 물-암석 반응이 진행되었고, 또한 저온의 열수변질작용이 중첩되었기 때문에 이들에 의한 단열충전광물의 생성기원 연구가 필요하다. Mineralogical characteristics of fracture-filling minerals from deep borehole in the Yuseong area were studied for the radioactive waste disposal project. There are many fracture zones in the deep drill holes of the Yuseong granite, which was locally affected by the hydrothermal alteration. According to the results of hole rock analysis of drill core samples, SiO2 contents are distinctly decreased, whereas A12O3 and CaO contents and L.O.I. values are increased in the -90 m∼-130 m and -230 m∼-250 m zone, which is related to the formations of filling minerals. Fracture-filling minerals mainly consist of zeolite minerals (laumontite and heulandite), calcite, illite (2M₁ and 1M_(d) polytypes), chlorite, epidote and kaolinite. The relative frequency of occurrence among the hcture-filling minerals is calcite ≥ zeolite mineral > illite > epidote >> chlorite kaolinite. Judging from the SEM observation and EPMA analysis, there is no systematic change in the texture and chemical composition of the fracture-filling minerals with depth. In the study area, low temperature hydrothermal alteration was overlapped with water-rock interactions for a long geological time through the fracture zone developed in the granite body. Therefore the further study on the origin and paragenesis of the fracture-filling minerals are required.

청소년 ADHD 평가 도구 개발을 위한 예비연구 : CASS(S)의 신뢰도 및 타당도 연구 RELIABILITY AND VALIDITY FOR CASS(S)

반건호,신민섭,조수철,홍강의 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.2

주의력결핍과잉운동장애(ADHD)는 소아질환으로 생각되었으나, 청소년과 성인에서도 문제가 되는 것으로 보고되고 있다. 질환의 유병율이 2.0∼14.3%로 다양하게 보고되고 있는데, 그 이유로는 질병 정의 기준의 차이, 평가방법의 차이 외에 연구대상자의 연령 차이 때문 등을 생각할 수 있다. 따라서 소아, 청소년, 성인을 대상으로 각각 적용가능한 ADHD 평가도구가 필요하다. 본 연구는 청소년에게 사용가능한 ADHD 유병율 평가도구의 개발을 위하여 Conners-Wells' Adolescent Self-Report Scale(Short Form)[CASS(S)]을 번안하여 신뢰도와 타당도를 확인하고자 하였다. CASS(S)는 세 명의 정신과 전문의와 임상심리전문가 한 명이 번안, 수정하였다. 공존타당도 및 검사-재검사 신뢰도를 보기 위하여 K-YSR 중 주의력 관련 9문항과 번안된 CASS(S)를 서울 시내 중학교에서 학년당 한 학급씩 선택하여 삼 개 학년에게 2주 간격으로 실시하였다(총인원 115명 : 남학생 58명, 여학생 57명). 신뢰도 평가를 위하여 내적일관성을 나타내는 Cronbach's alpha를 구하였다. 구성타당도를 알아보기 위하여 요인분석을 실시하였다. 요인분석을 위한 검사대상은 전국의 중고교생 4,354명으로 하였다. 연구결과 공존타당도를 알아보는 상관계수는 .65(p<.01), 검사-재검사 신뢰도를 알아보는 Pearson 상관계수는 .83으로 만족할 만한 수준이었다. 내적 일관성은 Cronbach's alpha .88로 만족할만한 수준이었다. 요인분석 결과 품행문제, 과잉행동문제, 인지문제의 세 가지 요인으로 나타났다. Although Attention Deficit Hyperactivity Disorder(ADHD) has been considered as the disorder occurring during childhood, the prevalence is increasing among adolescents and adults. The prevalence rate varies from 2.0 to 14.3% due to the difference of diagnostic criteria, different assessment methods, or subjects' age difference. Therefore, it needs to make age specific(i.e., for children, for adolescents, and for adults) assessment tools. Authors translated Conners-Wells Adolescents Self-Report Scales(short form)[CASS(S) in to Korean to get validity and reliability as a way of development of assessment tool for adolescent with ADHD in Korea. CASS(S) was translated and corrtected by three psychiatrists and one clinical psychologist. To examine the concurrent validity and test-retest validity, CASS(S) was applied with K-YSR on one class of each grade in a middle school in Seoul with two week interval(total 115 : male 58, female 57). To test validity, authors analysed and got Cronbach's as internal consistency. Construct validity was done by principal axis factor analysis on 4,354 students. As a result, Cronbach's alpha for internal consistency was .88, Pearson coefficient for test-retest reliability .83, and coefficient for concurrent validity .65. And in the factor analysis to examine construct validity, three factors were revealed as cognition, hyperactivity, and conduct. These results shows that CASS(S) may be useful tool for adolescents with ADHD, although there was a limit not to be done the comparison with clinical groups.

이수호,손무헌,조현철,김한근,사공 건 東亞大學校 1997 東亞論叢 Vol.34 No.-

In the fields of the optics, precise machine, semiconductors, the micro-positioning actuators are required for the control of position in submicron range. PNN-PZN-PZT cermics were fabricated with various mole ratio of the PZT[Pb(Zr½ Ti½)O₃] PNN[Pb(Ni⅓Nb⅔)O₃]and PZN[Pb(Zn⅓Nb⅔)O₃]powders prepared by double calcination and PZT powders prepared by molten-salt synthesis method. The formation rate of perovskite phase in PNN-PZN-PZT ceramics could be obtained about 92% at PZT 0.3 mole ratio. The relative permittivity of specimen with PZT 0.3 mole ratio was shown 5,320 and appeared the relaxor ferroelectric feature. The maximum piezoelectric coefficient d₃₁to be used for evaluation the displacement of piezoceramics in PNN-PZN-PZT ceramics was 324×10¹²(C/V) at the vicinity of morphotropic phase boundary and was larger than that of solid PZT ceramics(120×10-¹²C/V).

충남지역 활석광상에서 산출되는 금운모의 광물특성 및 기원

김건영,김수진,고용권,배대석 한국광물학회 2004 광물과 암석 (J.Miner.Soc.Korea) Vol.17 No.3

충남지역 활석광상에서 산출되는 금운도의 광물학적 특성 및 활성화 작용과 연관된 금운모의 생성기원을 연구하였다. 연구지역의 활석광상에서 산출되는 운모류는 녹니석과 더불어 활석광석의 주요 불순광물이다 화학적으로 활석과 공존하는 운모류들은 전형적인 금운모 조성을 보여주고 활석과 직접적인 관련이 없이 산출되는 운모류들은 흑운모에서부터 금운모 조성까지 광범위한 분포를 보여준다. 금운모는 주로 활석광체의 외곽부의 검은 변질대에 분포하며, 특히 괴상 활석광석에 수반되어 산출된다. 편광현미경이나 후방산란전자상에서는 금운모와 녹니석이 혼정을 이루고 있는 양상을 흔히 관찰할 수 있으며, 드물게 활석과 함께 혼정을 이루는 양상을 관찰할 수 있다. 금운모의 투과전자현경관찰결과, 일반적으로 전형전인 10Å의 격자상 내에 14 Å의 녹니석층이 불규칙하게 혼합되어 있기 때문에 금운모의 생성과정이 녹니석과 밀접한 관계가 있음을 지시하고 있다. 이러한 금운모의 산출상태와 광물학적 특성 및 금운모생성에 필요한 K의 기원을 고려하였을 때, 연구지역의 금운모는 활석화 작용의 후기단계에서, 포기 성분과는 달리 K을 충분히 함유한 열수용액과 활석 광체와의 반응에 의해서 주고 생성된 것으로 판단된다. K은 이러한 K-변질작용이 일어나기 용이한 구조조건을 가진 활석광체와 주변 화강암질 편마암과의 접촉부에서 화강암질 편마암으로부터 유입되었다. Mineralogical characteristics and genesis of phlogopite in the talc deposits of the chungnam area were studied. Mica is one of the major impurity of talc ores in the study area. Talc-related micas show typical phlogopite composition, whereas talc-unrelated micas show wide compositional variations between biotite and phlogopite. Phlogopite mainly occurs in the black-wall type zone, especially in the nodular talc ores near the outer part of talc ore bodies. Interleaving textures of phlogopite and chlorite are easily observed under the optical microscope and back-scattered electron images. Interleaving textures of phlogopite and talc are observed also. Examination of the phlogopite by transmission electron microscope reveals that 14 Å layers of chlorite are randomly interlayered within the 10 Å layers of phlogopite, which suggests that the genesis of phlogopite is closely related to chlorite. Considering the occurrence and mineralogical characteristics of phlogopite, and the possible origin of K for the formation of phlogopite, phlogopite of the study area was formed by interaction between talc ore body and hydrothermal solution containing sufficient K at the late stage of talc formation. K might be introduced from the granitic gneiss at the contact zone between the talc ore body and the granitic gneiss under favorable structural condition for the potash metasomatism.
