도시의 식재림을 자연림으로 복원하기 위한 기초로서 서울시 강남구 청담동에 위치한 청담근린공원내에서 교목층을 구성하고 있는 은수원사시나무를 벌목한 후 초기 2년간 맹아의 생장 및 맹아가 식생에 미치는 효과를 조사하였다. 벌목된 후 맹아의 발생량에서 모체의 기저면적이 넓을수록 맹아의 수와 생체량이 증가하는 것으로 나타났으며 후자가 전자보다 더욱 관계가 깊었다. 그리고 맹아의 생산량은 벌목 첫 해에 552.7g?DW/㎡, 맹아의 제거 후 익년에 8.7 g?DW/㎡이었다. 따라서 맹아의 제거는 익년의 맹아발생을 급격히 감소하는 결과를 초래하는 것으로 나타났다. 맹아를 제거하지 않은 지역에서 익년의 지상부 건중량은 657.4 g?DW/㎡에 달하여 맹아를 제거하지 않은 지역의 2년간 생산량보다 많았다. 특히 2년생 맹아의 높이는 304 cm에 달하였다. 맹아의 생장은 4월말부터 8월말까지 이었으며 매우 늦은 시기까지 잎이 남아 있었다. 비엽적은 시간이 경과함에 따라, 상층으로 갈수록 다소 감소하였으나 큰 차이가 없었다. 따라서 은수원사시나무 맹아의 생장이 빠른 것은 생육기간이 길고 하층의 잎이 생육후기까지 남아 있기 때문으로 나타났다. 은수원사시나무 맹아를 제거한 경우, 관목층의 구성종은 변화가 없었으나 초본층의 경우 종 수가 현저히 증가하였으며 관목층의 피도는 증가하였으나 초본층에서는 큰 변화가 없었다. 맹아를 제거하지 않은 경우, 관목층과 초본층의 구성종과 피도 모두 변화가 적었다. 그리고 맹아를 제거하지 않은 지역의 초본의 주요 구성종은 초장이 큰 미국자리공, 서양등골나물 및 큰기름새이었다. To develop the restoration technique from urban planted forest to natural forest, sprout growth and its effects on vegetation composition in the early stage after lumbering, were studied, using only Populus albaglandulosa of the tree layer in Chungdam Park Chungdam-dong, Kangnam-gu, Seoul during the two years from 1997 to 1998. The results were as follow. After lumbering, the more basal areas of the parent stump, the more sprouts were generated. The basal area of parent stump was related more to biomass than to the number of sprouts. In the cutting area, biomasses of sprouts were 552.7 g?DW/㎡ in first year and 8.7 g?DW/㎡ in second year after lumbering. Therefore, cutting of sprouts in first year resulted in decrease of sprout production in second year. In the non-cutting area, biomass of sprouts was 657.4 g?DW/㎡ and more than that of the experiment. Especially, 2-year sprouts grew to a 304 cm height by the end of the growing season in the second year. The growing season of sprouts was from early April to early September and almost all the leaves of the sprouts remained at the end of the growing season. Specific leaf area decreased along with time elapse and plant height but the differences were not conspicuous. Therefore, it is thought that the reason why p. albaglandulosa sprouts grew fast was due to a long growing period and lower layer leaves which remained at the end of the growing season. In the cutting area of the P. albaglandulosa sprouts, there were no changes in the number of species in the shrub layer but an conspicuous increase in the herb layer. Coverage was no changes in the shrub layer but an increase in the herb layer. In the non-cutting area of P albaglandulosa sprouts, the number of species and the coverage changed a little, and the main species of the herb layer were Phytolacca americana, Eupatorium rugosum and Panicum dichotomiflorum, which are tall plant species.

The aboveground production, nutrient distribution and nutrient cyclings were compared between two Phargmites communis communities growing in the different salt contents of soil in a coastal salt marsh. Inorganic nutrient contents of soil for plant growth were greater at the low salt stand than at the high salt stand except for sodium(Na). Maximum aboveground biomass of the plant at the low and the high salt stands were 2,533 and 1,719g dw/㎡, respectively, in August. Seasonal changes of nutrient content of biomass in dry weight decreased with growth except for Na. Nutrient contents in biomass per unit land area increased continuously as biomass increases, although the amonut of potassium(K) reached the maximum content in July and therafter decreased. Vertical distributions of total nitrogen(T-N) and phosphorus(P) increased with plant height, but Na showed the reverse trend. That of K was similar to the patterns for T-N and P in the leaves, and to the pattern of Na in the stems. The Na was greatly accumlated in underground biomass but transported scarcely to aboveground. Ath the low and the high salt stands, the ratios of the inorganic nutrients contained in the plant were 100 : 66 for T-N, 100 : 61 P, 100 : 62 for K and 100 : 97 for Na. The ratios of the amounts of nutrients retrieved to soil were 100 : 242 for T-N, 100 : 408 for P, 100 : 128 for K and 100 : 269 for Na, respectively. Turnover times of he T-N, P, K and Na in the communities were 56, 1, 15 and 174 years at the low salt stand, and 75, 2, 24 and 232 years at the high salt stand, respectively. In nutrient cyclings, all of the nutrients retrieving to soil were less than uptake by plant. Amo ng the nutrient, especially P is expected to be exhausted from soil, sooner or later, because of the harvest by men.

This study examined the relationship between Phragmites australis` growth and sediment properties at mud tidal flat of Donggum-ri, Gilsang-myeon, Gangwha-gun, Incheon city. Field survey was carried out from May, 2010 to October, 2010. Water content, soil texture, electric conductivity and water table depth for sediment, density, height, dry weight and flowering for P. australiswere examined at several plots from the starting point (the coastal embankment) to the end point of the two populations. The result was as follows. Firstly, the water table increased along distance from the embankment at one line (N-line) but was similar at the other line (S-line) in a P. asustralispopulation. Water tables were higher out of than within a P. australispopulation at two populations. Secondary, in N-line, the height and dry weight of P. australis decreased along the distance from embankment but, in S-line, those were similar in its population. P. australis` growth was dependent on electric conductivity at lower layer (water table level) rather than upper one (the surface). Thirdly, density of P. australis changed during growing season and was similar in a population, except for the end point of patch. In summary, the growth and distribution of P. australiswere dependent on salt content of tidal flat`s sediment (water table level) and this was affected by fresh water of the inland.

Morphology and karyotype of Korean Convallaria majalis plants were observed for taxonomic studies. Most plants produced two leaves(70%) and some one leaf(30%), but rarely three leaves. Plant length averaged 34.4±4.6㎝. Percentage of plants bearing flowers was very low with 3.7% (n=1.346) in the field. Raceme usually grew below leaves and rarely grew over leaves. Plant beared five to ten flowers on a single raceme. Chromosomes were x=19 and diploidy with 2n=38. The chromosomes were composed of 13 pairs of median and 6 pairs of submedian chromosomes. The number of chromosome and karyotype of Korean C. majalis plant agree with those of Japanese and European plants. [Convallaria majalis, chromosome, karyotype, morphological variation, taxonomy].

미래사회를 대비하여 창의적 이공계인력의 양성에 기여할 수 있는 잠재계층인 이과계열 고등학생들의 창의적 인성과 사고양식의 특성을 조사하고 관계를 확인하기 위하여 경기도 소재 고등학교의 이과계열 학생들을 대상으로 설문조사를 실시하였 다. 총 285명을 대상으로 결과 분석이 이루어졌으며, 창의성 인성에 따라 상하그룹으로 구분하고 사고양식의 특성과 상관관계를 분석하였다. 연구결과에 따른 결론은 다음과 같다. 첫째, 이과계열 고등학생들은 전반적으로 입법형, 계급형, 지엽형, 외부형, 자유형의 사고양식을 지니며, 창의적 인성과 외부형, 지엽형, 계급형, 입법형, 자유형순으로 유의미하게 높은 정적 상관관계인 것으로 나타났다. 둘째, 창의적 인성이 높은 그룹은 창의적 인성이 낮은 그룹보다 입법형, 사법형, 계급형, 무정부형, 지엽형, 외부형, 자유형의 사고양식을 유의미하게 더 선호하는 것으로 나타났다. 셋째, 창의적 인성이 높은 그룹은 지엽형, 무정부형, 계급형, 사법형, 입법형, 자유형 순으로 유의미하게 높은 정적 상관관계가 있으며, 창의적 인성이 낮은 그룹은 사법형, 외부형, 지엽형, 계급형, 입법형, 자유형 순으로 유의미하게 높은 정적 상관관계인 것으로 분석되었다. 그러나 보수형의 사고양식은 창의적 인성과 유의미하게 부적 상관관계인 것으로 나타났다. 따라서 이과계열 학생들의 창의적 인성을 함양하기 위한 교육적 활용방법으로 학습자가 선호하는 사고양식을 고려하여 교수학습 환경을 제공할 필요가 있으나 보수형 사고양식은 지양해야 할 것으로 시사되었다. In order to investigate the correlation and creative personality and characteristics of thinking style of high school students in natural science departments, which is a potential group that can contribute to the cultivation of creative science and engineering workforce in preparation for future society, a questionnaire survey was conducted for the students of natural science departments in the Kyonggi-do high school. A total of 285 respondents were used for the analysis of this study, according to creativity personality, high and low group were classified and their characteristics of thinking style and correlation were analyzed. The results of the study are as follows. First, the high school students in natural science departments generally have the thinking style of legislative, hierarchic, local, external, liberal, there was a significant positive correlation with creative personality in order of external, local, hierarchic, legislative, and liberal. Second, it was analyzed that high creativity personality group were more likely to prefer the thinking style of legislative, judical, hierarchic, anarchic, local, external, liberal than low creativity personality group significantly. The high creativity personality group has a significant positive correlation with the order of local, anarchic, hierarchic, judical, legislative, liberal, the low creativity personality group was a significant positive correlation with creative personality in the order ofjudical, external, local, hierarchic, legislative and liberal. However, it was found that the conservative thinking style had a statistically significant negative correlation with creative personality. Therefore, it is necessary to provide the teaching and learning environment considering the preference thinking style of the learner as the educational utilization method to cultivate the creative personality of the students in the science department, but it is suggested that the conservative thinking style should be avoided.

In this study a comparative analysis is conducted to evaluate TLSF(Teaching and Learning for a Sustainable Future) program, which is a module type environmental education program developed by UNESCO, and the Korean environmental education curriculum.<br/> The Korean environmental curriculum is mainly focused on conceptualization and the matters of fact. As a result, students may not be able to acquire contextualized and synthesized<br/> views on the environmental problems. The Korean environmental curriculum hardly supplies ample variety in the methods of teaching, learning and assessment, or the theories characteristic of the environmental education. Thus it would not make a useful material for teachers to reorganize various materials to be applied in class.<br/> TLSF program would be useful for a teacher to use in the environment education field because it supplies not only many various activities and samples for constructing a proper program but also the theoretical base and examples for education and assessment strategy. Finally, TLSF also offers the theoretical base of the environment education for the assessment, and it makes the best use of feedback from the environment educational field for improving its own quality.<br/> In conclusion, this study can be a meaningful preview for those who are involved in the process of developing of a curriculum, which consists of steps like formulating theories for developing a curriculum, organizing the curriculum contents, activating and evaluating a curriculum.

The research evaluated the effects of the improvements in scientific inquiry for elementary school students and focused on the development and application of the explicit and reflective learning strategy through observation and classification. The explicit and reflective learning strategy was modified and completed with the review of the experts after the development of the draft based on the theoretical approach. The students were evaluated for their academic achievements in scientific inquiry skills before and after taking the course. The results were as follows: First, the steps of the developed learning strategy ① to motivate, ② to explore reflectively, ③ to guide explicitly, ④ to inquire explicitly, and ⑤ to verify reflectively were set to reflect the verification. Second, the results of applying the developed model to the lessons based on the quantitative analysis was effective for observation and classification skills in the quest for improved performance of the whole (the sum of observation and classification, inquiry skills) and the observed features, but there was no effect on classification. Also, the lessons applied the developed teaching strategy and showed effectiveness in improving academic achievement. Particularly in analyzing the relationship between the academic achievement and exploration capabilities, in order to improve academic achievement, the importance of improving inquiry skills was found. Third, the qualitative analysis of teaching and learning strategy developed by applying the lessons of this teacher guide and small group activities through the explicit and reflective observation and classification of the student learning activities showed the significant improvement of ability of the scientific inquiry skills. In addition to the improvement in the abilities of the classification showed after the formation of the most basic observation skills of the scientific inquiry.
