This study was carried out to offer a basis data for application of effective management through species composition and community structure of Castanopsis cuspidata var. thunbergii stands (Bijindo and Yokjido). The upper, middle and lower layer in Bijindo and Yokjido consisted of 10, 11 and 27 species, and 9, 6 and 28 species, respectively. The importance value of Castanopsis cuspidata var. thunbergii were highest in upper and middle layer both two studied site. The herbaceous species were 33 and 47 species in Bijindo and Yokjido, respectively. The species diversity ranged from 0.523 to 1.280 in Bijindo and 0.699 to 1.364 in Yokjido. Dominance in Bijindo and Yokjido were 0.477 and 0.242 at upper layer, 0.231 and 0.102 at middle layer, and 0.106 and 0.057 at lower layer, which showed that Castanopsis cuspidata var. thunbergii stands are dominated by a large number of species at all layer. The distribution pattern by Morisita's index showed that Castanopsis cuspidata var. thunbergii was distributed randomly in upper layer both the studied sites.

To study the actual vegetation and vegetation structure of Tongyoung district and Yokjido (Island) in Hallyo-Haesang National Park, thirty seven plots were surveyed in July,1998. The vegetation structure of the surveyed plots were dissimilar in virtue of geographical isolation and artificial disturbance. The actual vegetation were classified into five group: Pinus thunbergii forest, P. thunbergii-P. densiflora- deciduous broad-leaved forest, deciduous broad-leaved forest, P. thunbergii-P. densiflora-evergreen broad-leaved forest, evergreen broad-leaved forest. P. thunbergii forest was a major vegetaion type of the surveyed area and evergreen broad-leaved forests were distributed at Ch'ubongdo, Yongch'odo, Pijindo, Yokjido and Youjado as a small patch. Successional sere shall be assumed from Pinus thunbergii, Pinus densiflora, and deciduous broad leaved trees to Neolitsea sericea, Cinnamomum japonicum and Persea thunbergii via Castanopsis sieboldii.

이번 탐방은 한려수도 내에 국내 최초의 육.해상 종합 휴양지인 경남 통영의 '금호 충무마리나 리조트'를 방문하였다. 이곳은 미륵도 관광특구 내에 자리 잡고 있어 요트나 유람선을 타고 인근의 거제도와 비진도, 욕지도, 연화도 등의 섬을 돌아볼 수 있으며, 주변 바닷가와 추도, 연대도, 투미도 등지에서는 바다낚시와 사냥도 즐길 수 있다. 특히, 주변에 세병관, 충렬사, 충무공유적지, 한산도, 거제도 등 관광지가 많아 한국의 나폴리로 불릴 정도로 빼어난 경관을 자랑하고 있다.

The V_S30 map is used as a key variable for site amplification in the ShakeMap, which predicts ground motion at any site. However, no V_S30 map considering Korean geology and geomorphology has been developed yet. To develop a proxy-based V_S30 map, we used 1,101 V_S profiles obtained from a geophysical survey and collected proxy layers of geological and topographical information for the Korean Peninsula. Then, V_S30 prediction models were developed using linear regression analysis for each geological age considering the distribution of V_S30. As a result, models depending on geomorphology were suggested per each geologic group, including Quaternary, Fill, Ocean, Mesozoic group and Precambrian. Resolution of map is doubled from that of V_S30 map by U.S. Geological Survey (USGS). Standard deviation of residual in natural log of proxy-based V_S30 map is 0.233, whereas standard deviation of slope-based USGS V_S30 map is 0.387. Therefore, the proxy-based V_S30 map developed in this study is expected to have less uncertainty and to contribute to predicting more accurately the ground motion amplitude.

최근 대학들은 학부제 시행에 따른 학생들의 교과목선택권이 확대됨으로써 수강신청시 학사진도를 강화해야 할 필요성이 대두되고 있으며, 학생들은 자신의 진로에 맞는 좀 더 바람직한 교과목을 선택하고 이수하는데 체계적인 도움을 필요로 하고 있다. 이에 본 연구에서는 학생들이 자신의 목표\ulcorner진로에 맞는 교과과정을 원활히 이수할 수 있도록 도움을 주고자 교과목선정에 대한 상담을 지원하는 지식기반 학사지원시스템을 개발하여 보고자 한다. 개발될 학사지원시스템은 지도교수의 시간부담을 줄이고, 학생들에게는 언제든지 상담을 받을 수 있도록 함으로서 수강신청시 교과목 선정을 보다 효과적으로 지원할 수 있을 것이다.

1960년대를 기점으로 하여 일어난 수학 교육현대화 운동은 범세계적인 문화현상으로서 발전하는 방향으로 철저히 진행되어야 했으나 교재내용을 지나치게 비현실적으로 도입함에 따라 교육의 현장에 선교사의 창조적 노력보다는 무비판적인 수학교육이 됨으로써 원래의 수학교육목표와는 달리 진도에만 급급하다. 현실적인 요인으로서 중등학교 진학률의 증가 및 평준화에 대한 원인도 있겠지만 시험에만 연결되는 교육에 이상적인 논리주의 구조주의 적인 수학의 도입도 적지않은 문제 요인으로 되어 있다. 앞으로 교과과정의 개선이 있겠지만, 우선 지도방법에 있어서 새로운 방법론이 시도되어야 할 것이다. 본 논문에선 학생들이 이해할 수 있는 범위내에서 수학사적 자료를 도입하여 수학의 역사 및 수학의 사상적 배경등에 접할 수 있는 기회를 주어 교과내용에 흥미를 유발하고 수업내용을 이해하는데 도움을 주는 방법을 모색하려는 것이다.

The purpose of this study was to investigate the effects of career decision self-efficacy and career maturity on employment stress in order to investigate the factors that can lower employment stress. For this purpose, the subject of 3rd and 4th grades 502 students in S university was analyzed by hierarchical regression analysis. The results of this study are as follows. First, gender and age were found to affect overall employment stress. Female students had higher employment stress than male students, and the older they were, the higher the employment stress. Second, career decision self-efficacy and career maturity had negative effects on employment stress. This study will be used as basic data for the career guidance of university authorities.

In this research, we observed how students perform as they followed the teachers' instruction, and consequently perform their realized potential. As the accountability of school education is emphasized, various attempts try to disconnect the vicious cycle of producing low achievers. Efforts are allocated into developing a method to minimize cumulative effect of the lag in educational benefit by focusing on the elementary education. Based on the 2007 revised curriculum, mathematics achievement level and assessment criteria were developed. These criteria were used to standardize the course and assessment objectives for 4th through 6th grade students' mathematics studies, and to assess lower performing students and the lag in their mathematical understanding. The educational materials and assessment criteria can be expected to lead lower performing students by giving them the personalized lesson plans to minimize the lag of mathematical understanding, and eventually expedite their progress and prevent cumulative effect of the lag in the following curriculum.

Auditory and language train for the hearing-impaired is an essential course improving conversational capability with non-deaf and accompanying the financial burden and the physical fatigue of parents or a teacher. To reduce these problems, web-based training contents have been developed. But these contents have been developed without consideration of individual difference such as various levels of residual hearing and the learning capability of hearing-impaired. Therefore, it is important that appropriate training progress for each hearing-impaired should be designed by evaluating and analyzing the personal status, residual hearing, learning capability and training achievement. This paper suggests auditory and language training service model for the hearing-impaired, which is planning and managing an auditory and learning training based on personal evaluation. In addition, this paper suggests a design method for a serious game content planing based on this service model.
