Accumulation of soil organic matter and its vertical distribution at different latitudes in peninsular Korea were studied in the soil of four different forest types viz. Pinus densiflora forest, Castanea forest, Quercus acutissima forest and Carpinus laxiflora forest. Among them, accumulation of soil organic matter in Cheju sites, with a mean annual temperature of 15$^{\circ}C$, was maximum with increasing latitude, soil organic matter concentration decreased. Considering the relationship between concentration of soil organic matter and some climatic conditiions, it seems that concentrations of soil organic matter is a function of annual temperature, especially warmth index or cold index.

The purpose of this study was to examine the effect of parenting behavior and parent-child communication on elementary school children's multiple intelligence. 321 children selected from two elementary schools and their mothers participated in the study. Data were collected using the multiple intelligence index, parenting behavior inventory and parent-child communication index. The data were statistically analyzed using the t-test, one-way ANOVA(Duncan test), and multiple regression analysis. The study showed that there were some significant differences in children's multiple intelligence according to the children's gender, income, mother and father's educational background. There were some significant differences in children's multiple intelligence according to the parenting behavior, warmth acceptance and permissiveness nonintervention behaviors, and to the parent-child open communication and problematic communication. It was also found that children's gender, family income, warmth acceptance behavior, permissiveness nonintervention behavior, open communication and problematic communication were all significant predictors of the children's multiple intelligence. Implications based on this study are as follows; in order to increase the children' multiple intelligence, parents should be warmer and more accepting and have open communication with their children.

This study examines the effects of paternal parenting behaviors, child-rearing involvement, and father-child communication perceived by children on their leadership. A total of 197 children selected from three elementary schools and their fathers participated in this study. Data were collected using a parenting behavior index, a child-rearing involvement inventory, a father-child communication inventory, and a children's leadership index and statistically analyzed using the t-test, a one-way ANOVA ($Scheff{\acute{e}}$ test), and a multiple regression analysis. The results show significant differences in children's leadership according to the father's education level, family income, the father's warmth/acceptance, the father's family activity involvement, and open/problematic communication between the father and the child. The child's age, the father's education level, family income, the father's warmth/acceptance, open communication, and problematic communication were significant predictors of the child's leadership. These results suggest that a child's leadership may be strengthened if the father is warmer and more accepting and has open communication with the child.

본 연구는 가야산국립공원을 대상으로 지리정보시스템(Geometric Information System, GIS)을 이용 식생분포에 영향을 미치는 요인들을 분석하여, 식생분포 확률을 기초로 가야산국립공원의 잠재자연식생을 추정하였다. 가야산국립공원의 현존식생조사 결과 128개의 군락이 분포하는 것으로 나타났다. 가야산국립공원의 고도, 경사, 사면방위, 지형지수, 연평균 온도, 온량지수, 잠재증발산량의 7개 요인을 중심으로 군락별 분포를 분석하였으며, 이를 바탕으로 분포확률을 추정하였다. 잠재자연식생의 분포확률이 0.3이상인 군락은 소나무군락의 출현확률이 55.80%로 가장 높았으며, 신갈나무군락이 44.05%, 상수리나무군락이 0.09%, 굴참나무군락이 0.06%로 나타났다. 식생의 분포에 영향을 주는 요인을 본 연구에서 제시한 요인으로 한정할 경우 가야산국립공원의 잠재자연식생은 신갈나무군락(43.1%)과 소나무군락(56.9%)이 나타날 것으로 예측되었다.

This study was carried out to clarify the climatic factors of the freezing injury for the judgement on the adaptation areas of evergreen broad-leaved trees. We surveyed and analyzed the climatic factors of the freezing injury to Machilus thunbergii Siebold & Zucc. on the streets with the analyzation of planting grounds, soil conditions and the surrounding buildings. This study showed that only the minimum air temperature factor out of the other climate elements, which were the annual precipitation; the average annual temperature; the average monthly temperature of january; the average monthly minimum temperature of January; the average temperature of the coldest month; the warmth index and the coldness index, was matched up with the previous theories and reports on the freezing damages on the evergreen broad leaved trees and Machilus thunbergii Siebold & Zucc. The freezing injury of Machilus thunbergii Siebold & Zucc was occurred when the mean minimum temperature of the coldest month(TMC) in winter season fell down below $-4.1^{\circ}C$ and the temperature fell down below $-9.2^{\circ}C$. The freezing damage on Machilus thunbergii Siebold & Zucc surrounded by high buildings were less than those surrounded by low buildings or at non buildings.

본 연구는 RCP 4.5와 RCP 8.5 기후변화 시나리오를 이용하여 서울시 온량지수 변화를 추정하였으며, 이에 따른 적응 가능한 식물종을 제안하였다. 기후변화 시나리오에 따라 서울시의 온량지수 변화의 차이는 있었으나 냉온대 남부림에서 난온대림으로 변화할 것으로 예상된다. 2010년부터 2099년까지 서울시 온량지수 분포변화를 예측한 결과에 따른 적응 가능한 식물종은 교목층에 졸참나무, 굴참나무, 소나무, 상수리나무, 때죽나무, 곰솔 등 6종이었으며, 관목층에는 쥐똥나무, 조록싸리, 개옻나무, 작살나무, 산딸기, 찔레꽃, 초피나무 등 7종이었고, 초본층은 주름조개풀, 고사리, 닭의 장풀 등 3종, 덩굴성식물에는 청미래덩굴, 댕댕이덩굴, 담쟁이덩굴, 인동, 계요등, 노박덩굴, 사위질빵, 멍석딸기, 마, 으름, 마삭줄 등, 등 11종을 포함하여 총 27종이 공통적으로 기후변화 시나리오에 따라 온량지수의 변화에도 적응 가능할 것으로 예상된다.

The moss flora and it's geoecological study were made on Mt. Odae which is situated in the easterm part(37$^{\circ}$43'N. Lat., 128$^{\circ}$30' E. Long) of Korea. The total number ofmosses collected on Mt. Odae in the autumn of 1960 is 50 species, 1 varieties and 1 subspecies, belonging to 23 families. For climate index, Warmth index and Humidity index were calculaterd on Mt. Odae. From the result, it was known that the climate of Mt. Odae is Humid temperate climate and that it's vegetation zone is Deciduous broad-leaf forest zone. Moss Quotient of this mountain is 1.21 and it indicates that the plant climate of Mt. Odae is Hemicryptophytic climate. The moss flora of this mountain was discussed from the pnytogeographical point of view. The flora consists of the following elements: Holarctic element : 20 species (38.5%) North Pacific element: 1 (1.9%) Cosmopolian element: 6 (11.6%) Tropical element: 1 (1.9%) East Asiatic element: 12 (23.05%) Korean-Japan element: 12 (23.05%) Coefficient of closeness was also calculated between the moss flora of Mt. Odae and that of Mt. Sulak and Mt. Kwanak. It was known, therefore, that the flora relation between Mt. Odae and the Mt. Sulak was closer than that between Mt. Odae and Mt. Kwanak.

본 연구에서는 RCP 8.5 기후변화 시나라오를 바탕으로 온량지수와 쾨펜의 기후구분을 통한 우리나라의 기후지대 변화를 살펴 보았다. 그 결과, 온량지수에 의한 기후지대를 구분하였을 경우 21세기 후반으로 갈수록 기온이 증가하여 전국적으로 난온대의 기후특성이 나타날 것으로 예상되었으며, 쾨펜의 기후지대 구분에서는 기온의 꾸준한 증가와 강수량의 연중 빈도 차이에 의해 Cfa와 Cwa의 기후특성이 주로 나타날 것으로 예상된다.

The effect of climate change on urban woody plants remains difficult to predict in urban areas. Depending on its tolerances, a plant species may stay and survive or stay with slowly declining remnant populations under a changing climate. To predict those vulnerabilities on urban woody plants, this study suggests a basic bioclimatic envelop model of heat requirements, cold tolerance, chilling requirements and moisture requirements that are well documented as the 'climatic niche'. Each component of the 'climatic niche' is measured by the warmth index, the absolute minimum temperature, the number of chilling weeks and the water balance. Regarding the utility of the developed model, the selected urban plant's present probabilities are suggested in the future climate of Seoul. Both Korea and Japan's thermal thresholds are considered for a plant's optimal climatic niche. By considering the thermal thresholds of these two regions for the same species, the different responses observed will reflect the plant's 'hardening' process in a rising climate. The model illustrated that the subpolar plants Taxus cuspidata and Ulmus davidiana var. japonica are predicted to have low suitability in Seoul. The temperate plants Zelkova serrata and Pinus densiflora, which have a broad climatic niche, exhibited the highest present probability in the future. The subtropical plants Camellia japonica and Castanopsis cuspidata var. sieboldii may exhibit a modest growth pattern in the late 21C's future climatic period when an appropriate frost management scheme is offered. The model can be used to hypothesize how urban ecosystems could change over time. Moreover, the developed model can be used to establish selection guidelines for urban plants with high levels of climatic adaptability.
