This research examines the effect of area level characteristics on individual health, particularly focusing on the vulnerable populations in Seoul. We consider adult individuals whose family income is under 1.5 million won, who are aged 65 and over, or who have neither spouse nor job but aged 40 and over as vulnerable populations. Using the 2005 Seoul Citizens' Health Interview Survey, we conducted multilevel analyses to simultaneously investigate the effect of area and individual level characteristics on health. Between-area variance of self-rated health status was greater for the elderly population than for all populations. Area material deprivation index and happiness index were associated with the self-rated health of economically disadvantaged populations. Vulnerable populations showed greater between-area variances in emotional health than the same for all populations. Area happiness index, material deprivation index, the proportion of households below poverty line and street safety showed statistically significant association with emotional health. The effect of area characteristics were particularly salient for the emotional health of elderly population and its between area variance was also notable.

Selection of training set influences the classification accuracy in supervised classification using satellite imagery. Generally, if pure pixels which character of training set is clear were selected, whole accuracy is high while if mixed pixels were selected, accuracy is decreased because of low-resolution imagery or unclear distinguishment. However, it is too difficult to choose the pure pixels as training set actually. Accordingly, this study should be suggested the suitable classification method in case of mixed pixels choice. To achieve this, a few pure pixels were chosen as training set and classification accuracy was calculated which was compared with classification result using an equal number of mixed pixels. As a result, accuracy of SVM was the highest among the classification method using mixed pixels and it was a relatively small difference with the result of classification using pure pixels. Therefore, imagery classification using SVM is most suitable in the mixed area of construction and green because it is high possibility to choose mixed pixels as training set.

The purpose of the present study was to investigate personality type with evoked potentials. Teenage students(121 males, 69 females) tested Myers Briggs Type Indicator and raven like discrimination task by evoked potential. Raven like discrimination tasks were made of low, medium and high levels. Conclusively extraversion and introversion while accomplishing the raven like discrimination tasks, showed the significant difference between two groups in the power of concentration. M-Beta(middle beta), Gamma and H-Beta(high beta) were also appeared significant differences between two groups. The sensing and intuition type partially appeared the different tendency of two groups while accomplishing easy and medium of difficulty tasks. Thinking and Feeling type while accomplishing raven like discrimination tasks, showed difference of the concentration power and H-Beta at Fp1. But judgment and perception type did not appear the difference between two groups while accomplishing raven like discrimination tasks of low, medium, and high. These results implied that the personality type can be affected brain wave by evoked potentials.

This study examined the effect of rope play through forest experience on children's self-confidence. Empirical analysis through the experimental design was carried out on an experimental group of 15 (seven male and eight female children) and a control group of 15 (nine male and six female children). Analysis of covariance (ANCOVA) for the effect between the experimental and control groups after the experimental treatment showed that the mean of the experimental group was significantly higher than that of the control group (F=357.350, p<.001). Rope play through forest experience has a statistically significant effect on the children's self-confidence. Consequently, rope play through forest experience between peers is a beneficial experience that helps improve children's self-confidence. Furthermore, it is a positive play activity to help them with a passive character boost to their self-confidence through cooperation between peers.

작은 국토 면적에 비해 잦은 산불피해가 발생하는 우리나라에서 영농활동을 위한 소각은 산불의 중요한 원인이므로, 이를 방지하기 위해서는 발화원인자인 영농인들의 의식조사와 관리주체인 산불관련 담당공무원의 의식조사가 필요하다. 이를 위해 영농으로 인한 소각행위가 빈번한 지방자치단체를 대상으로 영농소각으로 인한 산불 금지와 관련된 제도에 대한 설문조사를 실시하였다. 조사결과 소각 금지법에 대해 영농종사자들은 대체로 긍정적으로 인식하고 있었으며, 공무원들도 산불예방에 효과가 있다고 인식하는 것으로 보아 소각 금지법은 산불예방을 위해 지속되어야 할 것으로 판단된다. 영농종사자와 공무원 모두 공동소각이 산불예방에 효과가 있다고 답변하였으며, 이에 대한 활성화 방안이 필요할 것으로 판단된다. 소각 금지 거리 100m에 대한 적정성은 영농종사자와 공무원 집단 모두 긍정적으로 인식하는 것으로 나타났으며, 소각신청 허가서의 산불예방효과에 대해서도 양 집단 모두 긍정적인 인식을 가지는 것으로 나타났다. 영농폐기물 소각 근절을 위해 영농종사자들은 '기간 내의 신고에 의한 합법적인 소각'을 가장 필요한 대책이라고 인식하고 있었다.

This study was carried out to reveal the genetic population structure of the Jeju Island population and the phylogenetic relationship of East Asian populations of the large-footed bat (Myotis macrodactylus) based on the genetic polymorphisms of mitochondrial cytochrome B (CYTB) and NADH dehydrogenase subunit 1 (ND1) gene sequences. A total of fourteen and nine haplotypes were found in the CYTB and ND1 sequences from East Asian bats, respectively. Haplotype distribution showed locality specific patterns. The results from ND1 haplotype analysis showed that the Jeju Island population has four haplotypes: the Mt. Halla and Western subpopulations have three ND1 haplotypes, but the Eastern subpopulation has just a single haplotype Nd03, which is commonly found on this island. The neighbor-joining (NJ) tree showed the closer relationship between Jeju Island and Japan rather than that between Jeju and Gangwon-do Province. The divergence time between the maternal ancestor lineages of Japanese and Chinese populations was estimated to be 0.789±0.063 MYBP. The secondary divergence between Jeju and Japanese bats was calculated about to be 0.168±0.013 MYBP. The Jeju population has immigrated to the island at least fifty thousand years ago. In addition, ND1 haplotype analysis suggested that the insular bats have experienced at least two further genetic differentiation events within this island. Consequently, these findings suggested that the results of this study may play a critical role in understanding the phylogenetic relationship among East Asian bat populations of M. macrodactylus. To prepare more explainable information on evolutionary correlation, analysis is still required to examine using expanded samples from China, Russia, and southern parts of the Korean Peninsula.

We collected the samples of stream sediments from primary channels in order to establish natural background of major and minor elements for geologic units in the Gurye area. Stream sediments samples having no possibility of contamination effect and representing drainage basins composed of uniform geology, were collected from April to May in 1999, the chemical analysis of which was carried out. The tolerable level was used to investigate the enrichment degree of harmful elements. The contents of Ni and Cr exceeded the tolerance level in some sections. The tolerance level excess of those elements was regarded as the effect of the metamorphic rock which constituted the bed rock of the area. In order to identify the comprehensive enrichment pattern, the tolerable level was used in calculating the enrichment index. The enrichment index of harmful heavy metals showed that Granite gneiss area is 0.39, Porphyroblastic granite gneiss area 0.32, Biotite gneiss area 0.42, Migmatitic gneiss area 0.41, Tuff area 0.30, Andesite area 0.46, Conglomerate area 0.42, and Granite area 0.26. Those results showed that natural background of Gurye area had not been exposed to harmful heavy metal elements.

This study aims to propose safety culture design to ease to find out and control behavior characteristics of Korean seafarers. By empirical research of 377 Korean seafarers, the result revealed that significant characteristic of Korean seafarers was "affection to others" and custom of Confucianism affected Korean maritime society prevalently. But there were no significant differences between groups, such as rank, age, gender and sailing route with vessel type except educational background. Furthermore, this study concluded that positive reinforcement was more useful than negative reinforcement to promote safety operation of vessels. Regarding the vessel's safety management, the fact that means for vessel's safety management are linked only to the levels of educational background suggests that the efficiency of vessel's safety operation would be achieved by introducing suitable safety management system depending on the level of educational background.

Traditionally, surveys or interview studies have been used to measure satisfaction factors for public services. This method focuses on the simple frequency of civil complaints and does not consider the aggravation of emotions implied in civil complaints. As a result, it is difficult to judge the urgency of civil complaints and the severity of grievances experienced by civil petitioners. This study aims to calculate the negative emotional value of collective complaints by using the happiness score for each word on the Hedonometer. The Anti-Corruption and Civil Rights Commission applied a Hedonometer to the top civil complaint topics and related keyword data by region in 2021 to calculate negative sentiment values by subject of civil complaints, and visualize the distribution by region. Using the negative emotional values derived from the results of this study, the severity of emotions contained in civil complaints can be considered. It is also expected to be helpful in determining the urgency of civil complaints and the severity of grievances experienced by civil petitioners.
