Forest fire is due to difficulty in approaching the forest fire at the time of forest fire and quite a long of time required for post-fire investigation, accurate analysis of damages to the forest area caused by forest fire is difficult to obtain. Recently, In attempt to overcome such difficulty, many researches are using satellite images. Nevertheless, it is not easy for everyone to obtain the satellite image data, and additional researches in order to verify accuracy of such data are also required. Therefore, in this study for satellite image to about damages to the forest areas caused by forest fire using tile selected two data of spectral reflectance of the vegetation, gained by using a spectrometer. That is we wished to search about mistake that is apt to happen by one time eyesight observation by analyzing two datas that is used spectral radiometer 3 months and 6 months later and gets.

The senses that a doctor can feel is limited in MIS(Minimal Invasive Surgery) which guarantees the fast recovery of the patient and minimal incision for going in and out of instruments through the tissue of the patient. In particular, the surgical robotic teleoperation system developed recently serves with only the information of eyesight and auditory sense. Therefore force-reflection is the most demanded element of the senses in manipulating surgical instruments. In this paper, we designed the Master system and the 2 D.O.F grasper for the robotic teleoperation system(Slave) that has two force sensors on the grasper. Particularly, we focused on serve to master's handle with the contact force between tissue and the grasper of Slave.

In this paper, we proposed the spinning right-angle stereo vision system to center the shifted object on 3-dimensional image using a human eyesight-like, and the system is reconstructed with conventional stereo vision system. In this proposed system, the centering results of objects on the 3-dimensional image are very good, and we got the parameter ratios 89~112% for the real measurement values. Therefore, the suggested the spinning right-angle stereo vision system have a high possibilities to be applied to many industrial system parts and to be used for robot system, automatic system, and etc.

Particulate matter (PM) is a mixture of microscopic solid inhalable particles including airborne liquid droplets, and it is implicated with several diseases. The eye does not have a protective barrier among the human organs, consequently it get directly exposed to environmental substances such as PM. The scarcity of treatments for damage to the eyesight and the vision and eye structure being closely related to the structure and function of the central nervous system highlights the cruciality of novel therapeutics. In this study was conducted using in vivo zebrafish vertebrate model which is a useful model due to the conserved genes between human. We found that protective effect of Octopus minor extract against particulate matter-induced adverse effects on eye development in zebrafish (Danio rerio) embryos by regulating antioxidant and anti-inflammatory mRNA expression.

The purpose of this study is to compare the health status of Korean and Chosun-Jok elementary children. To accurately achieve the purpose, a survey was conducted in Yanbian area in China and Kojae in Korea during the period of June 15 to July in 1995. This survey was performed by using two survey methods. The first was the parents' survey method. It asked structured questions about their children. The second method focused on the actual health of the children. It used the collection of children's physical records in school. Guided by the school teachers, each child distributed the questionnaires to their parents. We used stratified-cluster sampling method to determine subjects. 1,083 questionnaires of 1,749 were used to analyze the data (666 questionnaires were incomplete and were not used in the analysis). Each questionnaire matched the data of their physical record. : Body Weight, Body Height, Chest-Circumstance, Eyesight, Dental Health. Using the data, we compared the BMI(Body Mass Index) the Koreans and Chosun-Jok in China. The results of this study were as follows : Comparing the general average physique of contained body height, body weight and chest circumstance of Korean and Chosun-Jok, the general physique of Chosun-Jok is inferior to that of Korean regardless of age and sex. Meanwhile, the average physical constitution of Korean compared the Chosun-Jok (i.e. eyesight and dental hygiene), revealed that the physical constitution of Chosun-Jok is superior to that of Korean without concern of age and sex. Average BMI of Chosun-Jok is lower than that of Koreans. But, it seemed that most of the students in both groups maintain an adequate health level. In the case of children from 10 to 12 years old, females are superior to males through all data contained of the body weight, the chest circumstance, and the body height. It seems that females and males have a different maximum growth age. Most of the parents preferred a good physique as a good health condition for their children. The physique of each child was affected with some variables, including the number of family members, and the educational level of the parents. According to the above results, the students' physique in Korea is superior to that of Chosun-Jok in China. But, Koreans are inferior to Ethnic Koreans in China in the students' physical constitution. In conclusion, we consider Chosun-Jok in China to maintain an adequate health level in their physique and physical constitution.

This study investigated how people who became blind midway through life used music and how these uses differed according to individual factors. Sixty-one late-blind adults aged 40 to 60 years attending six welfare centers for the blind in Seoul and Gyeonggi region participated in this research. Participants were asked to complete a 25-question survey in Braille on music utilization and preference, as well as the purpose of music utilization. The response rate was 87.1%. The results were as follows. First, with regard to listening preference, they reported preferring to listen to upbeat popular music on the radio when resting at home. They liked to sing along to lyrics reminiscent of personal memories. String instruments were preferred when playing an instrument. With regard to the reason for using music, inducing mood change was found to be the biggest reason, followed by seeking enjoyment, comfort, sense of achievement, and sense of belonging. Third, for people with adventitious visual impairments, individual factors, such as gender, level of disability, and period without eyesight, did not reveal any significant differences. Last, participants were found to obtain a higher sense of belonging through music compared to those having low vision. Regarding time without eyesight, it appeared that the shorter the period, the higher the sense of belonging participants had from utilizing music, and vice versa. This study provides fundamental information for organizing an effective music program that can meet the needs and demands of people with adventitious visual impairments.
