Science gifted students enrolled in a program, where classes had either explicit or implicit instruction about self-directed learning, were asked to write what was satisfying after each class. This process was part of the evaluation of the program. Students' descriptions related to self-directed learning are compared in these two classes, one with explicit instruction and the other with implicit instruction. First, most of the components related to self-directed learning, which were reported in the previous research articles, were mentioned in students evaluation. If there was any specific description regarding what was satisfying, there were components of self-directed learning. Students descriptions were consistent with list of self-directed learning components, which was constructed based on the previous research. Therefore it may be concluded that students recognized most of the reported self-directed learning components and satisfied with them. Second, There were differences in the evaluation of two types of classes. The evaluation of class with explicit instruction contained more self-directed learning components more frequently. For example, students worked in small groups in both classes. However more students mentioned small groups in classes with explicit instruction. As a result the explicit instruction appears to be more effective for students to recognize the self-directed learning components. However some of the components mentioned in classes with implicit instruction were not mentioned in the classes with explicit instruction. Therefore classes with explicit and implicit instructions are complimentary with each other and both instructions are necessary.

2009년 현재 기완료된 바 있는 화성 동탄 신도시를 시작으로 국내 12개의 u-city가 건설 추진 중에 있다. 또한 39개의 지구가 추진예정 중에 있으며 더욱 많은 지자체들이 u-city사업에 관심을 가지고 있다. 이렇듯 지대한 관심을 받고 있는 u-city의 구성요소 중 핵심이라 할 수 있는 도시통합운영센터는 도시정보를 효율적으로 취합하고 정보서비스를 제공하는 요소라 할 수 있으며, 그 구축방안에 대한 연구들이 활발히 이루어지고 있다. 하지만 도시의 여러 특성에 따라 적합한 센터의 구축방안에 대한 연구는 거의 이루어지고 있지 않은 실정이다. 특히 도시개발 유형과 관련하여 신도시를 건설하면서 u-city를 구축하는 경우 도시의 기반시설물 구축과 함께 u-city시설물 구축이 동시에 가능하지만 기존 도시의 경우 이미 구축되어 있는 도시기반 시설물에 u-city구축을 위한 시설물과 관련 기술을 적용해야 하는 차이점이 있다. 따라서 이러한 차이로 인해 각 유형의 도시통합운영센터 구축 방안에도 차이가 있을 수밖에 없다. 이에 이 연구에서는 우선 여러 가지 도시특성 중 개발 유형에 따라 도시의 유형을 구분하고 이를 중심으로 도시통합운영센터의 구축 시 고려해야할 점에 대해 살펴본다.

This study was performed in order to derive components that users with disabilities demand first when using library services by analyzing the actual usages and demands of handicapped users according to different types of disabilities. The results of the study are as follows: First, the actual situation of library disabled users was analyzed according to types of disabilities. Second, the importance and satisfaction level of disability types were investigated for the main components of the library disability service. Third, major components of library services were analyzed using Borich's Needs Assessment Model for the disabled and ways of activating library services by types were suggested. Fourth, we analyzed the differences according to different purposes of use by the disabled within Borich's Model for the main items of library services. We also proposed a plan to meet the purpose of library use by each type. Fifth, we analyzed the differences by type of users in Borich's Model for the major items of library services and thus suggested solutions to improve library services by types of disabilities.

Principal component analysis was used for ana1zing growth data to know the relationship between growth characteristics and yield as well as its components. The first principal component accounted for average time of the specific leaf area sampled, leaf area index, and dry weight, and the second component for the position of the changing point of growth characteristics. The component scores were more affected by the nitrogen level than variety. Yield were affected by fertility ratio and number of spikelets per hill which have close relation with the component score of leaf area index and dry weight per hill.

This experiment was conducted to identify the superior corn hybrids for silage production and to determine the combining ability of their parental inbred lines. A 7-entry diallel cross was evaluated for grain and stover yields, and agronomic characters under 3 different seasons. Hybrids Hi34 x Tx601, Hi26 x Hi34, and Hi29 x Hi34 showed high total dry matter yields. In general, late maturing hybrids had higher grain and silage yields than early maturing hybrids. Leaf area index was correlated with grain and stover yields. Rust rating was negatively correlated with yields and all characters, indicating that rust (Puccinia sorghi) was one of the major factors affecting yields. Diallel analysis showed that inbred Hi34 which was late in maturity and resistant to rust was the best combiner for both grain and silage yields. General combining ability (GCA) and specific com-bining ability (SCA) effects for yields and other characters were significant, suggesting that both additive and non-additive gene effects are involved for those characters. Ratio of GCA/SCA mean squares showed that GCA effects were more important than SCA effects for yields and other characters. GCA x season and SCA x season interactions were significant for grain and stover yields, revealing that gene effects were not stable for those yields under dissimilar environments.

복잡한 사회문제해결에 유용한 접근방법의 하나인 계층분석과정은 수학자인 사티(Saaty)가 개발한 것으로서 이미 사회과학의 여러 분야에 적용되고 있다. 본 논문의 목적은 이 계층분석과정을 간호교육과 관련된 문제에 적용해 봄으로써 이 방법이 실제 문제해결을 위한 유용한 접근방법이 될 수 있는가를 고찰해 보는데 있다. .현대사회문제들은 다양한 관련요소, 그 요소들간이나 다른 문제들과의 복잡한 상호관계, 다수의 의사결정자의 참여, 무한한 대안, 문제의 결과에 대한 불확실성 등으로 인하여 단순한 모델이나 간단한 논리적 혹은 직관적인 판단에 준하여 일시에 해결하기 어려운 경우가 많다. 이러한 상황 하에서 문제와 관련된 요소들을 찾아내고 그 요소들을 계층적으로 분석하여 단계적으로 문제해결에 접근하는 계층분석과정을 활용함으로써 사회과학분야의 문제해결에 유용한 수단이 될 수 있다. 또한 문제와 관련된 요소를 규명하고 계층적으로 분화하는 과정에서 그 문제에 대한 보다 명확한 이해, 분석 및 현상의 흐름을 더 잘 인해하게 된다. 계층분석과정은 1) 계층구조의 설정 2) 구성요소들의 중요도 측정 3) 중요도에 따른 우선 순위의 산정 4) 우선 순위의 일관성 검토과정으로 요약된다. 본 논문에서는 이러한 과정을 통하여 미국 간호계에서 심각한 문제로 대두되어온 기본교육제도상의 쟁점(Issue of Entry into Practice）에 대한 문제 해결책이 마련되는지를 시도하였다. 즉, 기본교육 제도에 영향을 미칠 수 있는 요인들을 규명하여 계층화하고 계층내에 위치하는 구성요소들의 수평적 관계와 계층간의 수직적 관계를 체계적으로 검토하여 간호교육의 미래를 예측해 보았다. 간호교육제도에 영향을 미칠 수 있는 주요 요인들의 계층화는 거시적 환경차원(factors), 관련 이해자 집단차원(actors), 이해자 집단의 목표차원(objectives), 목표달성을 위한 정책차원(Policies), 그리고 간호교육제도의 미래를 예견한 시나리오(scenario)로 이루어졌다. 각 계층을 따라 단계적으로 중요도를 비교하여 최종적으로 각 시나리오의 우선순위 중요도(priority weight)를 구하였다. 각 시나리오의 우선순위 중요도를 간호교육과 관련된 4가지 차원들(학생, 교수, 교육기관, 직업)을 구성하고 있는 특성들에 가중하여 결과를 해석 하였다. 간호교육의 미래에 정치적(55%)과 경제적(25%) 요인이 가장 강한 영향을 미치고, 관련자중에서는 병원(38%) 의사(33%) 그리고 정부(23%)의 순으로 영향을 미친다고 분석되었다. 의외로 간호원 자신들은 큰 영향력이 없는 것으로 보여졌다. 4개의 시나리오 중에서는 그 우선순위 중요도가 현상유지(33%) 자발적4년제(32%), 강제 4년제(19%), 그리고 2~3년제의 우위(18%) 순으로 나타났다. 최종 시나리오 결과를 요약하면 1) 전체 학생수는 감소하나 양질의 간호학생수는 증가하며 2) 박사학위를 소지한 간호학 교수 및 전체 교수의 수가 증가할 것이다. 3) 전체 간호교육기여의 수는 약간 줄 것이며 그중 4년제 기관이 증가하고 반면에 2~3년제의 기관은 감소할 것이다. 4) 전문간호원이 되기 위한 입학용이도에는 별차이가 없겠으나 간호원들의 보수, 지위 및 자율성이 증가하면서 전반적인 간호의 질이 향상될 것이다. 계층분석과정의 적용으로 미국 간호교육계의 가까운 미래를 위와 같이 예견하여 보았으나 이 과정은 예견 뿐 만 아니라 일반적인 의사결정이나 문제 해결의 도구이외에도 복잡한 사회문제의 본질을 분석, 이해함으로써 보다 정화한 정책문제를 규정하는 데에도 유용할 것이다.

The A detailed 3D finite-element analysis model of a human foot has been developed by converting CT scan images to 3D CAD models in order to analyze the distribution of plantar pressure. The 3D foot model includes all muscles, bones, and skin. On the basis of this model and the pressure distribution results, shoes for diabetes patients, which can make the plantar pressure distribution uniform, may be designed through finite-element contact analysis.
