  • In this review, we aimed to synthesize the current knowledge on the observed and projected effects of climate change on the ecosystems of Korea (i.e., the Republic of Korea (ROK) or South Korea), as well as the main causes of vulnerability and options for adaptation in these ecosystems based on a range of ecological and biogeographical data. To this end, we compiled a set of peer-reviewed papers published since 2014. We found that publication of climate-related studies on plants has decreased in the field of plant phenology and physiology, whereas such publication has rapidly increased in plant and animal community ecology, reflecting the range shifts and abundance change that are occurring under climate change. Plant phenology studies showed that climate change has increased growing seasons by advancing the timing of flowering and budburst while delaying the timing of leafing out. Community ecology studies indicated that the future ranges of cold-adapted plants and animals could shrink or shift toward northern and high-elevation areas, whereas the ranges of warm-adapted organisms could expand and/or shift toward the areas that the aforementioned cold-adapted biota previously occupied. This review provides useful information and new insights that will improve understanding of climate change effects on the ecosystems of Korea. Moreover, it will serve as a reference for policy-makers seeking to establish future sectoral adaptation options for protection against climate change.

  • As Korea is moving toward multicultural society, the number of Muslim, whose religion has a great influence on diet-related behaviors, is increasing in Korea. Since the number of immigrants from Indonesia ranks within top ten in Korea and Indonesia is one of the most representative Islamic countries in Asia, understanding the diet-related behaviors and food preferences of Indonesians is needed. This study was conducted to investigate diet-related behaviors, factors affecting the diet-related perceptions, and food preferences of the Indonesians. The subjects included 500 Indonesians dwelling in Jakarta, Indonesia. About ninety % of the subjects in this study were Muslims. They did not eat pork and dog meat for religious reason and they practiced fasting during Ramadan period. Indonesians avoided pineapple, durian, and hot foods during pregnancy and usually ate vegetables and fruits after birth, which seemed to be due to sociocultural influence. Among the subjects, 21.5% were obese and major health problems reported were hypertension and hyperlipidemia. Their preference for fried food items might have contributed to health problems. Subjects had meals mostly at home (2.3 times/day) and dined out occasionally (1.2 times/week) at Indonesian restaurants (56.6%) or family restaurants (21.0%). In conclusion, Indonesians had home-based and native food-oriented dietary life with strong religious and sociocultural influence on food choices. Further research on specific nutrient intake analysis is needed to better understand and to improve dietary life of Indonesians in Korea.

  • This study aims to find the association between community scales and perceived community family-friendliness among parents with young children. Communities were identified into three groups: metropolitan, small and medium-sized cities and rural, according to the degree of urbanization. The data were drawn from a sample of 1,038 parents who had at least one pre-school child. The data were analyzed by frequencies, means, GIS, ANOVA, and multiple regressions. This study compared the level of community family-friendliness both at the 'dong' and 'si' levels after controlling for the individual and household characteristics of the respondents. The findings of this study are as follows. First, after controlling for individual and household factors, the level of perceived community family-friendliness differed by the community scales. The parents in the small and medium-sized cities had higher scores on community family-friendliness than their counterparts in metropolitan communities. And parents in rural communities received had lower scores in community family-friendliness than those in metropolitan communities. The results also showed similar patterns for the 'dong' and 'si' models. While job and housing type were associated with the perceived family-friendliness of the community, other characteristics such as sex, age, educational level, monthly household income and home ownership were not.

  • To investigate the plant community structure of Chohangyoung valley in Soraksan National Park, thirty nine plots(each size was 100m$^{2}$) were set up and surveyed and to analyze the plant community characteristics of valley area and slope area, twenty five plots in five sites were set up and surveyed. According to DCA ordination techniques, the communities were six divided into community types, which were Pinus densiflora community, P. densiflora-Populus maximowiczii community, Po. maximowiczii-P. densiflora community, Po. maszimowiczii community, Fraxinus rhyuchophylla community, Quercus serrata community. Q. serrata community was only distrivuted at slope area and the others were distributied at valley area. The successional trend of six communities was not clearly inferred. Shannon's diversity was 0.9458~1.1769(unit area:500m$^{2}$), and soil acidity was pH 4.65~6.09 in surveyed areas. According to the belt-transect analysis, the dominant species of valley area were P. densiflora, Po. maximowiczii, but the dominant species of slope area was Q. serrata.

  • This study examined the status of the vegetation around Gangcheonsan provincial park located in Sunchang-gun in Jeollabuk-do and Damyang-gun in Jeollanam-do from June 4 to October 12, 2011. Gangcheonsan vegetation was arranged 9 plant communities in accordance with data of 28 releves. Major forest vegetation included Quercus variabilis communityand Quercus variabilis-Quercus serrata community, Pinus densiflora community, and Pinus densiflora-Quercus variabilis community (evergreen coniferous forest in all), and Phyllostachys nigra var. henonis community (plantation). Wetland vegetation included Salix gracilistyla community (riverbank forests), Phragmites japonica community, and Polygonia thunbergii community. Gangcheonsan Provincial Park has beautiful scenery that is in harmony with fantastically-shaped rocks, waterfalls, and valleys and conserves a specific plant community habitat distributed through the forest wetlands including its valleys. It is necessary to conduct long-term monitoring with its focus on Pinus densiflora community, Lycoris koreana community, and Lycoris squamigera community in the provincial park to grasp the characteristics of ecological inhabit changes in major communities and provide active methods for conservation, restoration, and publicity.

  • To investigate the forest structure and to suggest the management of vegetation landscape in Noinbong area, Pdaesan National Pa, twelve plots were set up and surveyed. According to the acalysis of classification by TWINSPAN, the community was divided by two groups of Carpinus laxiflora - Quercus mongolica community and the other is Betula costata - schmidtii - C. laxiflora community. It was found out that the successional stage of Noinbong forests was climax and introduced-climax by the analysis of species structure, similarity index and species diversity. The number of individuals was about 120~130 and species was 17 per 100m$^{2}$. Through the analysis of basal area and DBH class distribution, it was estimated that C. laxiflora, B. costata, and B. schmidtii will be clmax species instead of Q. mongolica in tree layer, and in the subtree layer, Acer pseudo-sieboldianum will be dominant species.

  • The purpose of this study was to provide the basic data needed for developing comprehensive child edu-care programs that fits the regional needs. Subjects of the survey were the teachers of child edu-care centers in Daejeon. 95 teachers were selected from 20 child edu-care centers, using stratified random sampling method, from all of five municipal districts of the city. Gathered data were analyzed using SPSS 10.0 for reliability, factor analysis, frequency and percentile, mean, standard deviation, paired samples t-test and F-test. The summary of the findings were as follows: First, the result of survey on the child edu-care facts showed that the most child edu-care centers had the focus on caring and education programs of children, while emotional supports for family services and community social services were rather secondary importance. Therefore, to achieve the comprehensive service programs, child edu-care services should be harmonized by the education and welfare approaches. Second, centered around teacher's request, comprehensive child edu-care program that fits the regional characteristics focuses on family service; thus the program requires family group consulting, parents education etc., as well as focusing on community service to utilize local community's human, physical resources and to strengthen the tie between local community and child care services.

  • The evergreen broad-leaved forest in Mt. Turyunsan was classified into four plant communities : Carpinus tschonoskii community, Carpinus tschonoskii - Quercus acute community, Quercus acuta community, Neolitisea sericea community. Quercus acuta, which had been appeared as a dominant species in most evergreen broad-leaved forest, was assumed to be succeed from Quercus serrata and Quercus variabilis through Carpinus tschonoskii, and would be succeed to Neolitsea serisea. Carpinus thschonoskii and Quercu serrata were assumed to be competitive with Quercus acuta, Camellia japonica, Neolitsea serisea and, Machilus thunbergii. It was assumed that Quercus acuta had a similiar ecological niche with Camellia japonica. Also it was assumed Neolitsea serisea had a similiar ecological niche with Lozoste lansifolia.
