Due to the increase of oil price, the needs of the reduction of the fuel cost is rising. Therefore, necessity of hybrid vehicle that runs with engine and the electric motor is on the rise. Hybrid vehicles have been developed into various ways including serial type, parallel type, power split type. In this research, multi mode hybrid power train system, which can implement more than two modes, is used as subject.
N. 스콧 모마데이의 『새벽으로 지은 집』 : 에이벌의 구전 전통 ‘기억하기’를 통한 외상 회복

This paper examines Momaday’s idea of the Native’s survival in House Made of Dawn, paying attention to his representations of Abel (a Pueblo Jemez, war veteran, traumatized protagonist who has suffered from his loss of cultural identity). In this paper, I will argue that the writer highly suggests the reading public to be fully aware of the significance of storytelling, by exemplifying the psycho-somatically battered protagonist’s ordeal and recovery through his ‘remembering’ of the Native’s culture (language, songs, and stories). This paper focuses on the events of Abel’s consecutive meetings with three storytellers (Angela, Benally, and Francisco) who all support him to ‘recall’ his hereditary songs and stories. First, Abel hears from Angela the legend of the ‘bear’ of the Kiowa tribe, which symbolizes vitality and valor. Next, when Abel lives a hard life in a white man-centered city, he meets Benally who remembers the Navajo traditions and encounters the Navajo s traditional song, Night Chant. With this Night Chant, Abel gets closer to tribal traditions and feels the importance of traditional worldview and consciousness. Returning to his hometown, Abel takes care of his dying grandfather Francisco. Francisco tells him various traditional stories from his youth and stresses the importance of staying connected to Navajo’s traditions. Accepting Francisco’s lesson and wisdom, Abel finally participates in Jemez Pueblo s traditional ritual of ‘dawn running’ and sings Night Chant. This experience helps him to heal his cultural trauma and restores his bond with the earth.

Objectives: The Korea Ministry of Environment regulates concentrations of hazardous air pollutants (HAPs) through Atmosphere Environmental Standards to protect public health from HAPs. However, simply determining the exceedance of HAP concentrations has several limitations and more comprehensive assessment is required. In addition, integrated risk assessment is needed considering exposure in all microenvironments, including outdoor as well as indoor environments. The purpose of this study was to assess the differences in risk by sub-population groups according to time-activity patterns and reported concentrations, as well as the lifetime risk for Koreans. Methods: In this study, we calculated time-weighted average exposure concentrations for benzene and PM 10 among preschool-age children, students, housewifes, workers, and the elderly using residential time and concentrations for indoor (house, school or workplace, other), outdoor, and transport by the meta-analysis method. The risk assessments were conducted by excess cancer risk and disease death risk using 1,000,000 Monte-Carlo simulations for probabilistic analysis. Results: Preschool-age children, students, housewifes, workers, and the elderly spent 91.9, 86.0, 79.8, 82.2, and 77.3% of their day in their house, workplace, or school, respectively. The more than 99% excess cancer risk for benzene exceed 1.0E-06 in all sub-populations and lifetime. The acute disease death risk for PM 10 for housewifes and workers for lifetime were 3.35E-04 and 3.18E-04, and chronic disease death risks were 2.84E-03 and 2.70E-03, respectively. Conclusions: The risk of benzene and PM 10 by sub-population group and for the lifetime of housewifes and workers were assessed. Benzene showed risky results for this study. All disease death risks of PM 10 were higher than 1.0E-04 and showed different risks by sub-population. This study can be used as a basis for lifetime exposure and risk assessment to benzene and PM 10 .

이 연구는 다문화가정 학생들의 학교급 별 교육지원 요구와 현황의 특성을 밝히고, 이에 따른 학교급 별 교육지원 방안을 제안함을 목적으로 한다. 이를 위해 다문화가정 학생에 대한 교육지원 프로그램을 분석하고, 학교급 별 교육지원 요구를 파악하였으며, 동시에 실제로 이루어지고 있는 교육지원의 현황을 조사하였다. 그런 다음 이를 바탕으로 학교급 별 지원방안이 제안되었다. 본 연구가 제안하고 있는 바는 다음과 같다. 유치원 급에서는 다문화가정 학생들이 공동체적 소통과 상호이해의 바탕을 마련할 수 있도록 언어교육과 문화교육이 중점적으로 이루어져야 하며, 초등학교 급에서는 그 목표는 유치원 급과 비슷하지만, 교육내용에서 언어교육 및 문화교육이 이루어짐과 동시에, 학교 제도에서 소통과 상호이해를 더욱 진전시키기 위해 다문화가정 학생들에 대한 학교적응교육이 실시되어야 한다. 중학교 급에서는 다문화가정 학생들의 자아정체성 강화 교육과 일반적 수준의 진로직업교육에 강조점을 둘 필요가 있다. 고등학교 급에서는 다문화가정 학생들의 학업성취와 관련된 교육지원이 이루어져야하며, 구체적 수준의 진로직업교육과 관련하여 본격적인 지원이 제공될 필요가 있다. 이러한 학교급 별 차별화된 교육지원 방안을 마련함으로서 한국사회의 다문화교육은 다문화 학생과 학교교육에 한 걸음 더 다가갈 수 있을 것이다. This study aims to discover the demand and present condition of educational support for the students of multicultural families. Based on the findings of them, it also aims to suggest the educational support plan according to the school levels. For this purpose, analysis of the present educational support program for the students of multicultural families has been conducted. On top of that, analysis of the education support demand according to the school levels, and investigation on the present condition of educational support has been conducted as well. Educational support plan according to the school levels for the students of multicultural families has been suggested based on these findings. Suggestions presented in this study are as follows. At the kindergarten level, language education and culture education are required to lay the groundwork for the mutual understanding and communication as a member of society. At the elementary school level, general objective of educational support plan is similar to that of kindergarten level. But for the educational contents, school adaptation education at the elementary school level is required for the development of mutual understanding and communication in the frame of school institution, as well as the language education and culture education. At the middle school level, general career-education and identity education need to be emphasized. At the high school level, educational support related to academic achievement, as well as more detailed career-education, is required. By suggesting these differentiated educational support plan according to school levels, multicultural education of Korean society will be able to approach the school education and the students of multicultural families one step closer.

Due to the increase of concern on envelopment problem, the needs of a eco car is rising. Also, on account of the increase of oil price, the needs of the reduction of the fuel cost is increased. Therefore, necessity of hybrid vehicle that runs with engine and the electric motor is on the rise. Hybrid vehicles have been developed into various ways including serial type, parallel type, power split type. In this research, it subjected a axis vibration phenomenon through the engine fluctuation and hardness of clutch for vibration characteristic analysis.
