To understand the traditional knowledge of botanical taxa in Jeju Island, a diachronic study was carried out by comparing the archaic and modern names of the native plants in Jeju Island. To identify the archaic names of the plants, five old documents (Sejongshillokchiriji, Shinjŭngdonggukyŏjisŭngnam, T'amnaji, Namhwanbangmul and Jejugyerok) that were written during the Joseon Dynasty between the 15^th and 19^th centuries were closely examined. A total of 131 taxa (65 families, 112 genera, 118 species and 13 varieties), 7.3% of the native plants known to be currently present in Jeju Island, was identified. Out of these, 21.4% was the plants found in the southern area. Among the five old documents analyzed for this study, Namhwanbangmul recorded the largest number of plants, 89 taxa. We closely examined the consistency between the modern and archaic names of each plant, and discussed the problems in matching the names of some plants analyzed in this study.

본문은 동북 3성의 지리, 역사, 연구 상황을 개술하고 착중하여 조선족이 동북 3성에 이주한 시기를 4개기로 나누어 그 분포 특징을 밝혔다. 4개의 시기는 (1) 함풍-동치년 시기 (2) 광서년 시기 (3) 선통-민국년 (4) 위만 시기이다. 매시기마다 조선족이 동북 3성에 이주한 역사 지리적 배경을 천명했고 당시 조선족의 이주 노선과 분포특징을 귀납하였다. (1) 조선족이 동북에 이주하여 온 노선은 모두 20개 노선이 있었다. 그중 이주 수량이 많은 노선으로는 종성-개산툰-용정 노선, 남양-도문 노선, 만포-집안 노선이다. (2) 압록강 유역의 중간진에서 중국 림강에 들어온 이주민이 가장 일찍 했다면 두만강 유역은 10-20년 더 높다. (3) 동북 3성 조선족 인구밀도는 두만강과 압록강에 가까울수록 크고, 멀수록 작다. (4) 압록강, 두만강 유역에는 평안도와 함경도의 이주민이 많고, 두 유역에서 북쪽으로 갈수록 조선 남부의 이주민이 많다. (5) 동복 3성 조선족은 산지보다 평원에 많이 분포되었는데 동북의 수전개발에 커다란 공헌이 있다. (6) 중국 조선족에 97.1%가 동북에 집중되나, 그중에서도 길림성에 1,811,946명으로서 전국 조선족 총수의 65.8%를 차지하고, 흑룡강성에 452,398명으로서 25.2%를 차지하며, 요넝성은 230,378명으로서 9.0%를 차지하고 있다.(1990년 통계) (7) 도시에 있는 조선족은 모두가 잡거하고 농촌에서는 잡거구도 있지만 대부분은 순 조선족 부락을 이루었다.

The purpose of this study is to analyze the educational effect of non-face-to-face classes in elementary school social studies using Minecraft. the fourth grade of elementary school is divided into experimental and control groups, and social studies using Minecraft are conducted for one semester. As a result of the study, the experimental group students who experienced elementary social studies classes using Minecraft showed a significant increase in achievement, learning attitude, and sense of place compared to the control group, focusing on questions, explanations, and opinions in the Minecraft virtual space It was confirmed that they were cooperating with each other.

This research was classified mountain areas with high ecological, environmental and resource value among the macro scaled terrain that can be checked at the space scale of less than 1:1,000,000 and analyzed the topographical characteristics. It has been confirmed that the mountains of the Korean peninsula belong to the groups IV, V, VI(classification by Kapos et al.(2000)) as a result of applying the quantitative standards for designation of mountain areas to the global mountain system. The area of mountains calculated using high resolution DEM is equivalent to 48% of the area of the Korean peninsula, and the result is quite different from the general idea of which 70% is the mountain area of the Korean peninsula. The mountain areas show the distribution of geomorphons, that is different from the plains and the hills and also, it shows the differences between the mountains of the groups IV~ VI classified according to the altitude. As a result of analyzing the relations among type pattern, slope, and relief, specific geomorphons are concentrated at $10^{\circ}$ and $20^{\circ}$ and it shows the possibility to classify the mountainous areas into two groups based on the result that the distribution of landform patterns are bimodal in the relation to the amount of relief.

The purpose of this study is to examine the relationship between children's walking safety or risk of traffic accident and the physical environments around 20 public elementary schools in Changwon-si, Gyeongsangnam-do. Field surveys were conducted to assess the street-level objective and subjective walking environments. The GIS method was used for measuring the neighborhood-level land use patterns. Children's walking safety and risk of traffic accident data were collected from the 6,381 grade 5 to 6 students attending 18 elementary schools through the questionnaire survey. Correlation analysis showed that walking safety and risk of traffic accident of the elementary students were associated with the number of temporary or permanent obstacles on the sidewalk, traffic safety signs, driveway and street intersections, street lights, and percentage of detached housing area and road area on neighbourhood-level. This research will promote to help with constructing a safe routes to school and walking-friendly healthy community.

In this study, the meteorology terms in the geography text books of North Korea which includes all of the meteorology educational contents in secondary school curriculum are compared with those in the earth science text books in South Korea. Forty science terms which are the same meaning but composed of different words are picked up to investigate the degree for 89 high school students in Chonnam province to perceive the meanings correctly. High school students' perceptions is on the average 30% higher in terminology of South Korea textbooks than in those of North Korea. But, students' perceptions on 9 North Korean terms is rather higher compared to South Korean terms. Twenty six (83.9%) terms which are difficult for high school students to perceive correct meanings are those lately composed of North Korean native words. Most of meteorology terms in South Korean textbooks are derived from the Chinese characters or imported from foreign language terms are easier for high school students to perceive correct meanings than those of North Korean terms derived from North Korean native language.

Smart phones mixed with mobile devices and computers are biggest change of information technology and user-installed applications of them provide various information and services which were only possible on PC and Internet in the past. They are expected to be used by ten million people in 2011 and people with disabilities can get easily information and location of disabled facilities using them. In this paper, we design a mobile information service system for person with disabilities, which provides various information and location of disabled facilities. We build information of disabled facilities using acquisition information through existing web sites and provide location based service with user's location.
