This study is aimed at validation of the Korean Version of the Perfectionism Inventory which was developed by Hill et al.(2004). To do so, exploratory factor analysis and confirmatory factor analysis with 167 science high school and 161 middle school gifted students were conducted. It appeared 6 factor structure consisting of 'Self-Evaluative Perfection Strivings', 'Parental Pressure', 'Planfulness', 'Striving for Excellence', 'High Standards for Others', and 'Organization', which does not support 8 factor of the original scale. As a result, Cronbach's ${\alpha}$ ranged from .78 to .92 for subscale of PI and .93 for the total scale. The fit of measurement model was found to be ${\chi}^2=1257.618$ (df=792, p=.00), TLI=.903, CFI=.911, RMSEA=.047, indicating most of fit indexes were acceptable. Also, the validity of the scale was examined by the correlations between the PI and MPS. PI Korean version is significant to confirm the factor structure and validity of perfectionism which was influenced by characteristics of gifted students and Korean culture. These results show that the PI is quite reliable and valid tool for measuring perfectionism for gifted students.

In this study, seismic isolation technology to the lighthouse structure is suggested and isolation effects on response reduction are studied for three types of isolation models with the proposed seismic isolation technology. A seismic isolation system is installed on the base of the lighthouse structure in model 1, on the base of the lighthouse lens in model 2, and on the base of both of them in model 3. The dynamic time history analysis verifies that in case of model 1, the earthquake loading is greatly reduced and the accelerations of superstructure are greatly reduced. Also, the inter-story drifts are very small and can be neglected. The isolated model is in translational state and can be seen as a rigid whole. as a results, model 1 is very effective to mitigate the influence of earthquake on structures. In model 2, isolation effects are valid but special care should be taken to failure of the non-isolated lighthouse sub-structure. In model 3, isolation effects are also valid but the effects are small. model 3 is less effective than model 1.

This paper aims to review the fairness of carriers' incentive schemes at Gwangyang port in 2010 and to show the desirable incentive allocation rules using the proportional and egalitarian rules under cooperative game theory. The carriers' incentive schemes at Gwangyang port in 2010 did not meet the no-envy and the efficiency, and satisfy the symmetry axiom. According to the research findings, the equal surplus method satisfies the axioms of equity, efficiency, symmetry, and progressivity. However, the uniform losses method meets the axioms of equity, efficiency, symmetry, and regressivity. We use a single allocation criterion of the total throughput to show the regressivity and the symmetry principles into the incentive scheme instead of using multiple criteria such as total throughput, increased volume, and coastal volume. The uniform losses method based on the total throughput can distribute the incentive amount according to the intent of the incentive schemes. Hence, we need to establish a rationing system to allocate reasonably the total amount of different types of incentives, avoiding the temptation to adjust the volume shipped between the ports of carriers considering the efficiency of allocation.

Constructivism gave many implications to science education but at the same time it has brought confusion about its implication to the field of science education. Hermeneutics has possibilities of being able to reduce confusion as well as opening a new horizon. Hermeneutics seeks the meaning of 'real understanding' through the concepts of horizon, hermeneutical circle, and fusion of horizons. Both hermeneutics and constructivism have positive attitude to students' pre-understanding and accept contextualization of knowledge. Thus, they both can criticize traditional teaching method and propose an alternative. Moreover, hermeneutics approaches human understanding holistically with the concept of horizon, and pays attention to the circularity of the process of human understanding. As a result, hermeneutics can open a new horizon and give new discourse to science education and contribute to the development of research and practice of science education.

History is not only Hegel's philosophical subject, but it corresponds to his entire system of philosophy. Because his system of philosophy is a description of the self-movement of spirit and 'world history' reveals the overall movement of spirit. Hegel's 'historical and philosophical standpoint' goes through the description of his entire system, and this tendency is more and more reinforced towards the later Hegel. If it is reasonable to find the corresponding relationship between Hegel's system of philosophy and 'world history', the relationship between 'objective spirit' and 'absolute spirit' must be systematically unraveled in the horizon of world history. The world-historical perspective in 'objective spirit' has the limit to consider 'modern European nations' as a final destination. On the contrary, world history that acts as a mediator in the transition from 'objective spirit' to 'absolute spirit' makes it possible to jump in absolute horizon by recognizing limitations of nation states and avoiding specific and limited conditions dialectically. So what is revealed through the study of 'world history' in Hegel's system of philosophy is that in the view of 'absolute spirit' of art, religion, philosophy 'political state' is not the end that all mankind should aim at. Therefore, it is undesirable only to criticize Hegel's philosophy of history as 'Eurocentrism'.

In elementary, environmental education have been doing in various subjects. The features of environmental instruction would be reflected on contents of environmental education and characteristics of each subjects. These contents of environmental education might be contained normative contents, and it is moral subject that treats these normative contents systematically. Then environmental instruction of moral subject in elemental school should be approach and inquire teaching contents related to environment education. In elementary school curriculum of moral subject, teaching contents related to environment are 'preciousness of life' and 'right views of Nature and protection of the environment'. By these contents, moral instruction can approach to life of animal and plants centered on the reason to take them preciously and relation between nature and humans centered on the moral consideration. It is a difference that approaches to the environmental education not by factual understanding but by normative understanding in moral instruction. It must be focused on ethical inquiry for normative approach and reserving identity of moral subject. Necessary conditions for ethical inquiry to the environmental instruction are moral status of things besides humans. For the ethical inquiry to the moral status of nature environments, teachers could be set the logic of instruction based on the developments of environmental ethics. Formal cohesiveness of environmental instruction could be developed in sequence of ethical inquiry on moral status to the life of animal, life of plants, and whole system of nature. For this, teacher could reflect on their instruction focused on some explanations. That is, it is explanation to the animal life based on the individual-extended human oriented ethics for human, plants life based on the individual-non human oriented ethics, whole natural system based on the holistic-non human oriented ethics. When teachers reflect these explanation, they can compose their instruction as 'finding something in common with humans and animals', 'reflection on the attitude to the commons', 'thinking about reasons on the different attitudes to the commons', 'the things that disappear as plants die', 'thinking on values about non organism'. These plan of instruction could be critically reconstruct by other teachers. But environmental consciousness by ethical inquiry should be hold on instruction to the environment reflected on identity of moral subject.

아동의 언어습득 과정에서의 모방은 흔히 볼 수 있는 현상이지만 한편 인간의 독특하고 신기한 일면이기도 하다. 이 모방에 관하여 그동안 많은 연구들이 되어왔으나 그 중요성이나 역할에 대한 연구들의 결론이 모두 일치하는 것은 아니다. 본 논문에서는 이 모방현상에 대한 그 동안의 연구들을 이론별로 분류해 보고 각 이론들이 모방의 역할을 밝히기 위하여 사용해 온 연구방법, 절차들을 분석해 보았다. 행동주의와 사회학습이론에서는 언어습득에서의 모방의 역할을 특히 강조하고 있으며 이 모방의 효과를 입증하기 위하여 다른 어떤 이론보다도 훨씬 조직적인 실험연구를 해 왔다. 이와는 대조적으로, 언어 심리학적 접근에서는 언어습득에서의 생득성과 창의성을 강조하므로 모방의 역할은 중시하지 않으며, 모방의 정의를 엄격하게 규정하고 자연적인 관찰 중심의 연구를 주로 하여 언어습득에서의 모방의 역할이 미비하다는 결론을 내리고 있다. Piaget 중심의 인지발달적 접근에서는 모방을 인간의 전체 발달의 한 측면으로 보아 모방은 인지발달과 함께 점진적으로 발달되는 것으로 설명하고 있다. 특히 언어발달에서의 지연모방의 중요성을 강조하고 있으며, 대부분의 연구는 자연적인 관찰연구를 통하여 모방의 발달과정을 밝히고 있다. 언어발달에서의 모방의 역할에 대한 지금까지의 일치하지 않는 연구 결과들은 각각의 이론들이 나름대로 달리 모방을 정의하고, 언어의 다른 측면들을 다루어 왔기 때문으로 밝혀 졌다. 앞으로 언어발달이 아동의 발달 전체의 맥락 속에서 연구되어지고, 언어습득과정에서 보이는 아동들의 개인차까지도 고려되어지는 포괄적인 연구가 이루어지면 모방의 역할도 좀더 명백하고 일관성 있게 밝혀지리라 본다.

기후변화로 인해 집중호우, 돌발 홍수 및 태풍의 규모가 대형화되고 있고, 이에 따른 수재해 피해 사례도 증가하는 추세이다. 특히 건설 현장 중 굴착공사 현장에서의 침수로 인한 사고는 인명피해로 이어질 가능성이 더 크기 때문에 더욱 주의가 필요하다. 하지만 현재 국내에서 실질적으로 굴착현장에 적용하기 위한 침수 대응 예측 시스템 및 구체적인 침수 예경보 체계, 기준, 매뉴얼은 존재하지 않는 실정이다. 따라서 본 연구에서는 굴착공사현장의 수재해 예방을 위한 침수 예·경보 시스템의 적용방안을 제시하였다. 또한 경제적이고 효과적인 측면을 고려하여, 공사현장 규모에 따라 적용하는 침수 예·경보 시스템을 이분화하여 소규모 공사현장에는 Track A, 대규모 공사현장에는 Track B 침수 예·경보 시스템을 적용하도록 제안하였다. 이러한 이유는 소규모 공사현장의 특성상 전체 공사비가 작고 운영되는 장비와 인력이 제한적이므로 침수 예·경보에 필요한 비용과 인력 투입이 어려울 수 있기 때문이며, 또한 대피가 필요한 전체 인원이 대규모 현장에 비해서는 적기 때문에 비교적 신속하고 원활한 대피가 가능할 것이라고 판단하였기 때문이다. 본 연구에서는 각 시스템별 적절하다고 판단되는 예·경보 기준을 제시하였다. Track A에서는 강우법에 의한 최소한의 경보시스템으로 필요한 안전목표를 달성할 수 있도록 고려하였고, Track B에서는 현장인원 대부분이 성인 남성임을 고려하여, 성인 남성의 부상을 유발할 수 있는 수심(H)과 유속(V)의 곱을 척도로 하는 한계 H·V곡선을 기준으로 운영되는 경보시스템을 제안하였다.

The purpose of this study was to investigate the effects of three kinds of horticultural activities (HAs) on attention concentration of elementary students. We selected 20 students using a Wee Class counseling office at J elementary school in Yeongcheon, and divided them into experimental and control groups composed of ten students each. The experimental group participated in three HAs including flower arrangement, planting, and pressed flower. Each HA was composed of three sessions and a session proceeded for a week. For the examinations of attention concentration, two groups responded the questionnaires before a week of the first session and at the end of the 9th session, only the experimental group participated in the measurement using grid by Harris before a week of the first session and at the end of each HA every week. The results of questionnaire survey showed that the scores of problem in emotion and problem in controlling, and the total score decreased 9.2, 7.8, and 19.0 points, respectively (P < 0.05), indicating that the attention concentration of the experimental group improved compared with the control. In the measurements using grid by Harris, the flower arrangement, planting, and pressed flower activities increased the scores by 2.22, 2.49, and 2.41 points compared with the pre-HA of 6.00, respectively (P < 0.05), that means the improvements of attention concentration. At the post-HAs, the flower arrangement, planting, and pressed flower activities increased the scores by 1.12, 1.39 and 1.31 points compared with the control group of 7.10, respectively (P < 0.05). In conclusion, the indoor HAs improved the attention and concentration of elementary students irrespective of kind of activities.

This thesis examined interpreting methodology of Do Won Lew Seung Kug(1923~2011) is based on the principle of Juhng-yaug. His lifelong academic aim was searching for the theory that enables global community to co-exist peacefully through humanitarianism that leads to reconciliation and mutual benefits. The research of the history of Korean thoughts provided him with the clue for his theory. According to Do Won, Korean thoughts pursue the Juhng-yaug's value of 'Yin and Yang accordance' rather than the I-Ching's value of 'suppress Yin and elevate Yang'. He furthermore asserts the concept of the middle (中), which harmonizes the two extremes by human beings as main agents, has been consistently observed from the action of divination during the ancient period through Juhng-yaug in the late 19th century. Do Won identifies 'human maturity that integrates the extremely conflicting insistences and values and seeks to be reconciled' as the basic character of Korean thoughts. He explains 'Hongikingan[弘益人間, becoming beneficial to the human world] is the idea that embraces the conflicting values symbolized by heaven and the earth. He also illuminates that Choe Chi Won(崔致遠)'s created Poongliu Do by integrating heterogeneity among Confucianism, Buddhim, and Daoism and it was attainable through the various works of mature human beings. Both Toe Gye' s philosophy of Ingeuk(人極, the Great Ultimate of Person) and the concept of Innaecheon(人乃天, Human Being right is Heaven) of Donghak are excellent examples of Humanitarianism that sublate two extremes. In Korea, the prototype of this thought has penetrated its entire history in the various circumstances of the period. The grand finale is Juhng-yaug of which the pursued values are 'Yin and Yang accordance' and mature humanitarianism revealed by the thoughts of the Person of the Central Ultimate (皇極人,至人) and Central Ultimate (皇極). Therefore, Humanitarianism in Korean thoughts clearly makes its appearance by the time of Juhng-yaug and it functions as a keyword to illuminate the entire history of Korean thoughts in reverse.
