The phenomenon due to the abundance of material civilization, and the destruct of environment provokes the damage to the order of nature in the earth. To prevent the fact, the necessity of the ecology start to become influential an important issue. In an outlook on the world of the ecological concept, human evolves with an environment as the mutual interdependence eventually. The approaching of the ecological method to reform of the present environment is an essentiality. In a viewpoint, the interior landscape starts to distinguish as an ecological concept in interior environment. To recognize the necessity of an interior landscape, comparison and analysis have been carried out in the worldwide examples of the lobby space in high-rise office buildings. In the results, the interior landscape is an essential fact to create an ecological interior environment. As the perceiving of the importance in the composition of the ecological environment, it needs to recognize the imminence the introduction of the ecological concept in the human life.

The purpose of this study was to investigate the relationship between three aspects of clothing behavior ana three personality traits. Personality traits were measured with Chung's Personality Scale. 1 The questionnaire measuring clothing behavior consisted of items designed to assess clothing conformity, importance, and self-concept regarding clothing, This questionnaire was composed of items designed for this study in addition to items selected from questionnaires of such researchers as Sin, Lee, Chung, creekmore, Cheek, and Kim. These questionnaires were administered to 323 high school girls in Seoul. Statistical analysis consisted of correlation and t-test. The results were : 1) Dominance was positively related to self-concept regarding clothing and negatively related to clothing conformity. 2) Emotional stability was positively related to clothing modesty. 3) Sociability was positively related to self-concept regarding clothing. 4) There was no significant difference in clothing behavior between early adolescents and late adolescents.

At Present, high-quality paper finishes are obtained by the exclusive un of supercalenders and softcalenders. Experience has shown that both calendering processes will not always k able to meet future requirements of increased efficiency combined with improved paper finish. The answer to these challenges is the development of a new technology, a synergy of supercalender and soft-calender called the “Janus concept”. This paper outlines the rationale behind this new development as well in the technical characteristics providing for the successful online integration irrespective of production speed. Laboratory results are included ta demonstrate that the Janus Concept enables a high-quality SC finish even at PM or CM speeds.

Next Generation High Speed Train having a distributed electrical motor system has just been developing to aim the experimental maximum speed at 400km/h since August, 2007. This project is in stage of concept design and so, it needs to take some review and analysis the characteristics of suspensions on the view of concept design. A train dynamic modeling is modified with the one car model presented in the previous conference and it was extended to 6cars models having the same suspensions and added some connection's characteristics between the cars with Vampire program. It is used to analyze the effect on the dynamic performances according to the variation of primary and secondary suspension characteristics in the condition of 6 cars configuration. The results would be useful to manage the potential risks in the next stage of basic and critical design that will be done by the manufacturing company.

The main purpose of this study was to examine pathways from maternal parenting behavior to externalizing problem behavior through deviant peer affiliation and self-concept. A sample of 405 high school students (184 boys and 221girls) in the Gyeonggi-do region of South Korea completed questionnaires focusing on maternal monitoring and adolescent deviant peer affiliation, self-concept, and externalizing problem behavior. Data were analyzed by structural equation modeling. The results demonstrated that maternal monitoring indirectly influences adolescent externalizing problem behavior through deviant peer affiliation and/or self-concept. When maternal monitoring was perceived as low by adolescents, they were more involved with deviant peers. This was followed by a more negative self-concept. Finally, negative self-concept resulted in more externalizing problem behavior by adolescents. The results emphasize that deviant peer affiliation plays a crucial role in increasing adolescent externalizing problem behavior.

The purpose of this study is to investigate the degree of concept understanding on the stratum for elementary school students. For this objective, questions on the stratum concept were developed, and concept survey was conducted for random sampling of $5^{th}$ and $6^{th}$ grade 536 students. As a result, students chosen correct answers of the average 57.4% for 16 questions. Below the average rate of correct answers in each domain were 1 question in the definition of the stratum, 3 questions in formation of the stratum, and 4 questions in features of the stratum. Especially, the percentage of correct answers were appeared in lowly that the difference between the visible side and non visible side on the stratum, the definition and formation process of a fault and the main cause of the stratum's exposure. Also, between the residence, grade, and gender of students, there were significant differences in 2 questions, 7 questions, and 1 questions, respectively. Therefore, many elementary school students do not have high understanding about the stratum concept. Through the results of this study, it can be contributed to find an efficient ways as a basic data for modify misconceptions of the stratum to the scientific concept.

Tall & Vinner(1981)의 연구는 개념 학습에 관한 중요한 패러다임을 제공함으로 써, 다양한 내용 영역과 학교급에 대하여 반복적으로 수행되어 왔다. 이 연구에서는 상위 집단 학생들의 함수의 연속에 대한 이해라는 관점에서 Tall & Vinner(1981)의 연구를 반복 수행하였으며, 그 결과를 분석함으로써 우리나라 상위 집단 학생들의 고유한 특성을 도출하고자 하였다. 우리나라의 상위 집단 학생들은 함수의 연속을 용어의 구어적 의미나 시각적인 심상에 의존하여 이해하기보다는 개념정의와 직접 관련지어 파악하는 경향이 있었다. 학생들이 보여준 개념이미지는 5가지 유형으로 분류되었으며, 이를 통하여 이후의 학습에서 상위 집단 학생들이 부딪힐만한 인지적 갈등 상황이 어떤 것인지 간접적으로 파악할 수 있었다.

This research purports to analyze released items and G4 students' science achievement from TIMSS 2011 according to their academic achievement levels and gender. By doing so, it aims to draw educational implications for Korea from analyses results. Korea showed a lower rate of students at the advanced international benchmark - the highest achievement level - compared to Singapore. The difference was the smallest in Life Science among three content domains and knowing among three cognitive domains. The results of analysis according to gender showed that male students' achievement was significantly higher in Physical Science and Earth Science, and their achievement was also higher in the cognitive domains of Knowing and Applying. From the analysis of the released items, it was revealed that the students' achievement was low in items related to classification of organisms, functions of heart, matters that combust or emit light, and the concept of rotation. Moreover, students drew some illogical conclusions based on their personal experience. Male students were found to show high achievements in items that were not included in curriculum, constructed-response items in the form of short-answer questions, and multiple-choice items in the Knowing domain. Female students were found to show high achievement in items that were included in curriculum, constructed-response items that require reasons and methods, and items that represent experimental situations. Male students showed high achievement in forces concept and movements concept of bodies in the universe, while female students showed high achievement in solubility concept.

본 연구는 삼각함수와 관련된 과제를 통해 고등학교 학생들의 함수 개념 이해 정도를 Hitt(1998)의 층위 분석을 통해 살펴보았다. 우선 학생들의 함수 이해 정도를 층위 분석을 통해 단계를 구분한 후 이해 관점을 과정과 대상 관점으로 다시 분류하였다. 그 결과 고등학교 학생들의 함수 개념 이해의 정도 층위는 3단계에서 불완전성을 보였다. 그리고 함수의 이해의 관점은 그래프 해석에서 과정 관점이 주를 이루고 있으며 대수적 표상의 조작이 중요시되고 있음을 알 수 있었다. 이러한 결과를 바탕으로 삼각함수를 다양한 관점으로 이해할 수 있는 교수-학습 방법에 대한 연구와 함께 문제 해결과 그에 따른 표상 체계 사이의 일관성이 유지되는 함수 개념 이해 층위 5단계에 도달할 수 있는 수업모델의 연구가 필요할 것으로 보인다.
