등대는 전통적인 기능과 역할에 충실한 항로표지일 뿐만 아니라 사람들의 향수와 해양문화의 기억들이 묻어있는 공간이다. 최근에는 적절한 해양문화공간으로 개발함으로써 해양문화에 대한 인식을 높이고, 지역관광에 공헌을 하고 있는 추세이다. 특히, 해양수산부는 2006년 "희망의 빛 조형등대 설치계획"을 통하여 마산지방해양수산청 소속의 통영시 도남항 동방파제 등대를 건설하였다. 지역과 문화적 특색을 살릴 수 있는 기념등대로 개발하고자 하였으며, 이에 따라 통영의 훌륭한 문화적 성과를 기념대상으로 지정하였다. 이에 현상공모를 통해 한국해양대학교의 안웅희 교수의 작품이 당선되었다. 본 연구는 기존의 등대의 형태에서 벗어난 추상적이면서 기하학적인 형상을 통해 통영 일대의 문화적, 관광적 요소에 미치는 영향을 살펴봄으로써, 향후 등대건축의 방향성을 제시하고, 다양하게 검토되어야 할 논제들을 밝히는 것에 그 목적이 있다. The Lighthouse is not only functioning as a traditional aids to navigate for the vessel, but also space that has memory about marine culture and man's nostalgia. Recently, it contributes to regional tourism and makes a new meaning about marine culture through the development of lighthouse to a proper space of ocean culture. Especially, MOMAF has constructed the sculpture lighthouse in Tongyeong as "the light of hope-sculptural lighthouse project". They hoped to develop the memorial lighthouse that represents characteristic of the region and culture and it became a symbol of the great culture in Tongyeong. Through the competition, prof. Ahn Woong-Hee's design won the project, and constructed. For this situation, we intended to reveal in this study that all the issues which relate to the design for lighthouse in the future through the abstract, geometrical form of lighthouse that deviated the traditional design.

The major characteristics of the developed corn hybrids were compared at each different planting time; 1st time(April 28) and 2nd time(August 20), respectively. Among traits surveyed, stem height showed highly at 1st time than 2nd, while ear height, stem diameter and ear length were similar at two times. Sugar content of the used hybrids showed highly at 2nd planting time than 1st. Pericarp thickness was also high at 2nd planting time. Especially, among hybrids CNU99 was the highest in stem height and ear length, CNU11 and CNU56 were high in sugar content, and CNU51 and CNU124 were thiner than other hybrids in pericarp thickness. Accordingly, these hybrids will be planted and recognized in 2nd yield trial for superior corn hybrid selection.

푸리에 변환과 웨이브렛 분석을 통한 주의력결핍ㆍ과잉운동장애아동과 정상아동의 사건관련전위 비교 연구

주의력결핍 ㆍ 과잉운동장애 아동과 정상 아동의 청각적 집중 과정의 차이를 비교하기 위해 13명의 남자 환자와 8명의 정상 남자아이에게 청각적 주의집중 과제를 제시하고 사건관련전위를 푸리에 변환과 웨이브렛 분석법으로 비교 조사하였다. 각 군 아동의 표준자극과 표적자극에 대한 사건관련전위 파형을 푸리에 변환을 통해 주파수 차원에서 서로 비교하였고, 각 군 안에서 표적자극과 표준자극을 주었을 때의 진폭을 비교하였다. 표준자극에 대해서는 거의 대부분의 주파수와 좌측 위치에서 주의력결핍 ㆍ 과잉운동장애 아동이 정상아동보다 의미 있게 높은 전압을 나타내었다. 반면 표적자극에 대해서는 주의력결핍 ㆍ 과잉운동장애 아동이 정상 아동보다 더 높은 전압은 보이는 경우가 의미 있게 감소하였고 정상 아동이 주의력결핍 ㆍ 과잉운동장애 아동보다 큰 진폭을 나타내는 경우는 의미 있게 증가하였나. 이런 결과는 주의집중을 반영하는 Nd파형의 푸리에 변환 결과에서도 나타났다. 즉 주의력결핍 ㆍ 과잉운동장애 아동은 무시해야 하는 자극에 대해서는 정상 아동보다 지나치게 강한 반응을 보이지만 정작 과제를 수행해야 하는 자극에 대해서는 정상 아동보다 더 약한반응을 보이는 경향을 보였다. 주의력결핍ㆍ 과잉운동장애 아동은 정상 아동 보다 표적자극에 의한 진폭 증가를 보인 전극과 주파수 영역이 적었을 뿐 아니라 일부 파형은 표준자극을 주었을 때보다 표적자극을 주었을때 오히려 진폭이 의리 있게 감소하여서 이들이 표적 자극에 대해 활성이 억제됨을 알 수 있었다. 정상 아동들은 표준자극보다 표적자극에 대해서 거의 모든 전극 위치와 주파수 대역에서 의미 있는 진폭의 증가를 보였으나 전전두엽과 전두엽의 전극에서는 주의력결핍 ㆍ 과잉운동장애 아동이 더 큰 진폭을 보이는 경우가 관찰되었다. 웨이브렛 분석 결과 표준자극에 대해서는 주의력곁핍 ㆍ 과잉운동장애 아동이 정상 아동보다 자극이 제시된 후 0∼300msec 사이에 일어나는 전위가 통계적으로 의미 있게 컸다. 이런 차이는 주로 전전두엽과 전두엽 앞쪽, 그리고 측두엽 일부와 후두엽에서 두드러졌다. 그러나 두정엽과 중앙 영역의 전극들은 특히 300∼370msec 이내에 일어나는 전위에서 정상 아동이 더 활발한 전기 활동을 나타내었다. 표적 자극에 대해서는 두 군 모두 표준자극보다 전기 활성이 더 증가한 양상이었다. 표적자극에 대해서 주의력결핍 ㆍ 과잉운동장애아동은 전전두엽과 전두엽 영역에서는 여전히 정상 아동보다 더 활발한 전기 활성을 보였으나 두정엽과 측두엽에서는 정상 아동이 더 큰 진폭을 나타내었다. 이로써 주의력결핍 ㆍ 과잉운동장애 아동은 무시해야 하는 자극에 대해서는 지나친 반응을 보이며 주의집중을 필요로 하는 자극에 대해서는 정상 아동보다 저하된 반응을 보이는 것이 확인되었다. 이와 함께 푸리에 변환 등 주파수 차원 분석법과 웨이브렛 분석 방법의 유용성을 알아보았다. 중심 단어 : 주의력결핍 ㆍ 과잉운동장애 ㆍ사건관련전위 ㆍ푸리에 변환 ㆍ 웨이브렛 분석. Using Fourier transformation and wavelet analysis, we compared the auditory event-related poten-tials of the patients with attention deficit-hyperactivity disorders (abbr. ADHD, 13 boys) and normal control children (8 boys) Amplitudes of the event-related potentials which were calculated via Fourier transformation were compared between the groups and between conditions (non-target versus target) in each group. To the non-target stimuli, the patients with ADHD showed significantly greater amplitudes across almost all of the electrode sites and frequencies. To the target stimuli, the incidents which ADHD patients showed much higher amplitudes than normal controls significantly decreased, while those of the reverse results increased significantly. These results were consistent with the comparison results about negative difference wave (abbr. Nd wave) using Fourier transformation. In summary, it was proved that non-target stimulus which should be ignored elicited more robust electrical response from the patients with ADHD than normal children, but the target stimulus which required active processing did much less electrical activity in the patients. For the patients, they showed much inhibited electrical response to the target stimuli in some electrodes and frequency ranges. Normal children were more strongly stimulated by the target stimuli in almost all electrodes and frequency ranges than the patients, but less in prefrontal leads and frontal leads. Wavelet analysis results proved that early responses (0-300msec) to the nontarget stimuli of the patients were significantly greater than the normal controls in prefrontal, anterior frontal, some parts of temporal, and occipital lobes and that late response (300-370msec) were significantly lesser than normal children in parietal and central electrodes. Target stimuli elicited significantly higher electrical activity in both group than non-target stimuli did. Prefrontal and frontal lobes showed stronger responses in the patients than normal children irrespective of stimulus condition, but parietal and temporal lobes did higher activities in normal children than the patients only to the target stimuli. In conclusion, the patients wish ADHD showed much greater responses to the stimuli which should be ignored, but failed to activated the necessary processes to the target stimuli. Also, we found that the frequency-dimension analysis and wavelet analysis were useful for the signal processing such as event-related potentials. KEY WORDS : Attention deficit hyperactivity disorder ㆍ Event related potentials ㆍ Fourier transformation ㆍ Wavelet analysis.

김희웅,곽기영 한국경영과학회 2004 韓國經營科學會誌 Vol.29 No.1

Critical success factors (CSFs) have been replicated and applied in a wide variety of settings for more than two decades Most previous research on CSF have focused on identifying critical factors, based on the variance theory, in terms of the correlation between individual factor and information system (IS) success However, it is unknown how a set of critical factors influence each other and lead to IS success, which means the process of IS implementation In this research, we aim to understand how a set of critical factors influence each other and lead to IS success in the context of IS implementation for Customer Relationship Management based on the process theory. This reseach has implications in explaining a mechanism leading to CRM systems success based on the influencial relationships among the critical factors.

The dynamic fatigue-life equation is applied to the uniaxial tensile test. On this study, we show that the fatigue limit values can be extracted from the tensile testing data. Consequently, those experi-ments can be correlated and the fatigue limit can be found by the tensile test. The theory is verified by comparing the theoretical fatigue limit from tensile test to experimental fatigue limit from fatigue test. The results can be used to find the reliable fatigue limit by tensile test.

In order to product and develop questionnaire which can assess the schizotypal personality by model of criteria in DSM-Ⅲ-R, it was presented following question in this study. First, for the validation and manufacture of scale and sub-subscale that assess overall feature, nine characteristics of the schizotypal personality disorder, this study was concerned with validity, reliability and factor-analysis results of schizotypal personality questionnaire. Second, we would by present how schizotypal personality disorder trend is connected with trait-anxiety, hopelessness and self-concept. Also the difference is compared with. Finally, 396(male 216 Ss/53,8%, female 180 Ss/45.5%) college students with mean age 21.2 years were sampled. Raine(1991)'s schizotypal personality questionnaire(SPQ) which assess nine characterisitics of schizotypal personality disorder in DSM-Ⅲ-R was translated and used. In this results, Raine's schizotypal personality questionnaire was appeared to have high internal validity, split-half reliability and test-retest reliability. Also, 6 factors were affirmed by empirical confirmation through factor-analysis. 6 factors have been very reliable internal validity that ranges from .78 to .83. In these 6 factors, idea of reference, odd or eccentric behavior and odd speech were corresponded to the category model after DSM-Ⅲ-R in Raine's scale. 'Cognitive, perceptive' dimension was centered of factor 1, 'Emotive, affective' dimension was centered of factor 2, social anxiety and constricted affect were constituted to 2nd factor. No close friends, schizoid trend and suspiciousness of schizotypal characteristics were constituted to 3rd factor by 'interpersonal relationship' dimension. These empirical outcomes which confirmed through factor-analysis were very valid and connected much to Raine's scale which assessed schizotypal personality disorder, thus possibility of development and manufacture of schizotypal personality disorder scale through item revision was lighten. In 2nd study the higher schizotypal personality disorder trend, trait-anxiety and hoplessness were higher. But on the contrary, self-concept was lower. The group of high score in schizotypal personality questionnaire had more trait-anxiety and hopelessness than the group of low score in schizotypal personality questionnaire. Contrastly, positive self-concept was high in the group of low score. Also the most predictable variable to the trait-anxiety was factor 2, predictable power R²of factor 2 was 29.1%. To the hopelessness, factor 2 was the most powerful predictable variable. Predictable power of factor 2 was 11.2%, also. In self-concept, factor 2 explained 20.8% of self-concept, thus it was presented that factor 2 had the most powerful explanatory quantity. In these consequences, the factors which have meaningful connection to the trait-anxiety, hopelessness and low self-concept within 6 factors were really factor 2, 3, 1. Among these factors, "Emotive' feature of factor 2 including social anxiety and constricted affect have the most effect on trait-anxiety, hopelessness and self-concept. And next to factor 2, the isolated interpersonal relation which include no close friends and schizoid trend was some influential variable. Also peculiar, unusual preceptual experience, eccentric belief and magical thinking had some effect though small. The college students who had strong schizotypal personality trend had more social anxiety and more constricted emotional empathic ability, less self-expression, less social skill than common college sudents. These elements threaten, interrupt and retard identity establishment and intimacy-seeking which are important developmental tasks within this period. These experiences is accepted to ego-dystonic to schizotypal college students who have some or moderate reality testing, adaptive ability. Moreover, These peoples would feel locus of contol externally, not internally and would have more control-failure experiences. All these elemets elevate anxiety level, give rise to low self-concept and low expectation to the future. These outcomes all confirmed questions which presented in this study.

대기중의 오존이 느티나무(Zelkova serrata Nakai)에 미치는 영향을 open-top chamber를 이용하여 관찰하였다. 2개월동안 대기중의 오존에 노출시킨 식물의 광합성율과 엽록소함량은 activated charcoal로 filter한 chamber의 식물에 비해 각각 60%정도 낮았다. 증산율과 stomatal conductance 도 non-filtered chamber 내의 식물이 charcoal-filtered chamber내의 식물에 비해 40%정도 감소되었다. 그러나 오존에 의한 가시피해는 관찰되지 않았다. Effects of ambient ozone on Zelkova serrata were observed by using open-top chambers. Net photo synthesis rate and total chlorophyll content were about 60% decreased in non-filtered chamber plants compared with charcoal-filtered chamber plants were also 40% lower compared with charcoal -filtered chamber plants. However, no visible symptoms of ozone were observed.

In resent times, the analysis of power system by the method of phase coordinates which uses the phase quantites directly has been studied extensively instead of the method of symmetrical components. In this paper, the power system components are modelled in terms of the phase coordinates representation, and some results are obtained from the sample power systems based on this model. In addition, in order to demonstrate further effectiveness and reliablity of phase coordinate method, its results are compared with those from the method of symmetrical components. In simulation, simple models are used for the analysis of power system, but this method can be extended to any number of systems.

학습장애를 가진 초등학교 남학생의 자아상 개념과 우울-불안 특성 조사

신성웅,김봉수,성덕규,정영,유희정,조수철 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

학습장애를 가진 86명의 초등학교 남학생과 52명의 정상적인 초등학교 남학생의 자아상과 우울,그리고 상태-특성 불안에 관하여 피어스-해리스 자아상 척도, 소아우울척도(이하 CDI), 상태-특성불안 척도(이하 STAI)를 이용하여 조사하였다. 피어스-해리스 자아상 척도의 총점에서는 두 군 사이에 차이가 발견되지 않았으나, 지적 및 학업 상태 항목과 신체적 외모, 행복과 만족 소척도에서는 두 군 사이에 의미 있는 차이가 관찰되었다. 소아우울척토의 총점과 그 소척도 중 부적합함, 무쾌감증, 부정적인 자기 존중 항목에서 학습장애 아동이 정상 아동보다 더 높은 점수를 나타내었다. 상태불안은 정상 아동보다 학습장애 아동에서 높게 보고되었으나 특성 불안에 대해서는 차이를 보이지 않았다. 정상 아동에서는 나이에 따른 자아상과 우울척도, 불안척도의 의리 있는 변화가 관찰되지 않았으나, 학습장애 아동에서는 피어스-해리스 자아상 척도와 그 소척도의 대부분이 통계적으로 의미 있게 감소하였고, 소아우울척도의 부정적 감정과 무쾌감증, 부정적 자기 평가, 상태 불안, 특성 불안 등은 연령과 의미 있는 양의 상관관계를 나타내어서 학년이 올라갈수록 자아상은 저하되고 우울과 불만은 느끼는 강도와 범위가 증가하는 양상을 보였다. 두 군 모두에서 소아우울척도는 피어스-해리스 자아상 척도의 총점과 그 소척도들과 의미 있는 역의 상관관계를 나타내었고, 상태불안과 특성불안과는 정의 상관관계를 나타내었다. 조사 결과 학업과 관련된 자아상의 문제와 자신이 남들과 당당히 맞설 수 있는 자신감의 문제가 학습장애에서 더 많이 나타났고, 나이가 들수록 자아상이 저하되며 불안과 우울은 증가하는 것으로 나타났다. 회귀분석 결과 학습장애 아동의 자아상을 설명하는 변수들로는 나이와 자아상 척도의 행동문제, 지적 및 학업상태, 불안, 인기도, 행동과 만족, 그리고 소아우울척도의 부적합함, 대인관계문제, 부정적 자기-존중 및 상태 불안인 것으로 드러나서 학습 장애 아동의 자아상은 학업 문제와 자신을 또래와 비교하여 겪는 스트레스로 인해 부정적인 영향을 받는다는 것이 확인되었다. 결론적으로 학습장애를 가진 초등학교 남학생은 정상 초등학교 남학생보다 자아상이 낮고 우울과 불안을 더 많이 느끼며, 이런 차이는 학년이 올라갈수록 커졌다. 학습장애에서 우울증과 불안 장애가 많이 동반되기 때문에 임상에서 학습장애 아동을 치료할 때 정서 장애의 동반 여부를 확인하고 이를 적극적으로 치료하는 것이 중요한 과제이다. 중심단어 : 학습장애 ㆍ 자아상 ㆍ 상태-특성 불안 ㆍ우울증. We investigated the self-concept, subjective depression, and state-trait anxiety of the school boys with learning disabilities (abbr. LD, n=86) and compared them with normal boys (n=52) using Piers-Harris Self-Concept Inventory, Child Depression Inventory (abbr. CDI), and State-Trait Anxiety In-ventory (abbr. STAI). With regard to Piers-Harris Self-Concept Inventory total scores, there was no significant difference between two groups, but normal boys showed higher scores in intellectual and school status, physical appearance, and happiness-satisfaction subscales than patients with LD. The male patients with LD showed significantly higher ratings in CDI total scores, and CDI subscales - ineffectiveness, anhedonia, negative self-esteem than normal children. The patients with LD reported significantly higher state anxiety, but not trait anxiety. Correlation analyses revealed that self-concept decreased over time, and depression-anxiety increased across grades in the patients with LD, but not in normal children. Especially, negative mood, anhedonia, negative self-esteem subscales of CDI, and state-trait anxiety showed significant positive correlation with grades. In both groups, CDI scores were inversely correlated with Piers-Harris Self-Concept and positively with State-Trait anxiety. In conclusion, self-concept problems which were related with school achi-evement and self-esteem were more abundant in the patients with LD than normal children, self-image problem, depression and anxiety increased across grades. According to regression analysis, age, behavior subscale, intellectual - school status, anxiety, popularity, happiness- satisfaction, CDI-ineffectiveness, interpersonal problem, negative self-esteem, and state anxiety could explain the self-concept in the patients with LD, not in normal children. So, the self-concept of the patients with LD were found to be related to the school achievement and stress when comparing with peers. In conclusion, elementary school boys with LD showed lower self-concept, higher depression and anxiety, and these differences increased across grades. Since the patients with LD have concomitant depression and anxiety disorders, it is important that comorbidity with emotional problems should be explored and managed properly. KEY WORDS : Learning disability ㆍ Self-concept State ㆍ trait anxiety ㆍ Depression.
