As part of researching the feeding habit of Liobagrus somjinensis, the study of its stomach contents and benthic aquatic macroinvertebrates fauna at the waters the fish was collected were carried out monthly from January to December 2010 in Yo stream, Somjin River Sikjeong-dong, Namwon-si, Jeollabuk-do, Korea. In the survey of the stomach contents, the prey organisms are all aquatic insects consisting of 5 orders, 14 classes and 16 species. They fed mainly on Trichoptera and Ephemeroptera including dominant insects such as Hydropsyche kozhantschikovi (79.1%), Chironomidae spp. (48.7%), Baetiella tuberculata (34.2%) at the occurrence rate. Based the result, L. somjinensis appeared to be an aquatic insect feeder that consumes only benthic aquatic insects. The feeding rate of L. somjinensis was the highest in November, whereas it was the lowest in December to next February when they did not feed in the winter season. A survey of the benthic aquatic macroinvertebrates fauna was accompanied for prey preference at the waters. They have 7 orders, 20 classes and 27 species, and among them, two species, Hydropsyche kozhantschikovi (39.0%) and Epeorus pellucidus (18.1%), were aquatic dominant insects. Among 7 orders interestingly, Odonata and Megaloptera, known as having a larger size than other aquatic insects, were not found at the stomach contents. As a result, Liobagrus somjinensis most prefer Hydropsyche kozhantscikovi which is the most dominant species with relatively a smaller size at the waters the study was performed.

In this study, the landscape characteristics of the sacred Dangsan forests at Singi-ri, Namwon-si were investigated as an agricultural heritage, and the management scheme for revitalization of the village was introduced. FAO established the term of 'GIAHS' (Globally Important Agricultural Heritage Systems) for conservation of each country's farmland, unique agricultural landscape, and cultural diversity. The Ministry of Agriculture, Food and Rural Affairs of Korea evaluates that the Agricultural Heritage is a new means and potential for rural development. Dangsan forest, a traditional village forests of rural Korea is a representative 'agricultural heritage' with a history of more than several hundred years of Dangsan ritual. The Dangsan forests were closely linked with paddy fields. This forest was composed of two Dangsan forests, and one Bibo forest. Especially, the Dangsan forest 2 was established on the mounding with 395m in length and 15m in width. Although, most of Dangsan forests do not have accurate records about forest establishment, this forest has retained a stone monument that illustrated the history of the forest. These aspects of Singi-ri's Dangsan forest indicated clear difference and characteristics compared to other ones. This Dangsan forest has been left alone from the public attention. The Dangsan forest at Singi-ri need to be recognized for their valuable landscape characteristics. By linking the Dangsan forest with 'Jirisan trail', the trail path will lead people to the agricultural heritage at Singi-ri. Enhancing the management scheme will contribute to revitalize the village.

The purpose of this study is to investigate the potential water condition of Honam region according to water budget analysis. For this purpose, the eight regions (Suncheon, Gwangju, Jhangheung, Damyang, Mokpo, Yosu, Huksando, Namwon) are selected as study area. The result is as follows. (1) The water surplus indicating the potential water condition is ordered as Yosu, Sunchon, Changhung, Namwon, Damyang, Huksando, Kwangju, Mokpo. So the potential water condition of Kwangju and Mokpo is worst among study regions. (2) The high water surplus region is corresponded to high precipitation and low actual evapotranspiration legions. (3) The potential water condition is to agree with several facts about the water resource condition of Honam region. For example, large scale dam of Honam region has been constructed for Kwangju and Mokpo city. This fact indicates that the potential water condition calculated by water budget analysis is corresponded to actual water resource condition. (4) Consequently, the water budget analysis is effective method for investigating the actual water condition and establishing the water resource management of specific regions.

The relationships between children's health behavior and variables that effect children's health behavior has been investigated in a number of previous studies. This study was conducted to examine the effects of a peer's social reinforcement on children's dental health behavior in an elementary school. The research design was a nonequivalent pre and post-test quasi-experimental design and the study subjects with one hundred and thirteen eight to nine years old children, and their mothers (57 experimental group, 56 control group) were selected as a study group. Subjects were selected by the convenience sampling method. The study was carried out in an elementary school in Namwon city, Korea, from the 26th of April to the 12th of June in 1999. Data were collected in both the pre and post-test portions. Using the "Health Belief Model", each item of the questionnaire for measurement of dental health behavior was modified and administered for the children and their mothers. The questionnaire for the measurement of dental health behavior was developed by Oh, Y.B.(1994). The Cronbach's ${\alpha}$ of the questionnaire for children were .81, and for the mother were .79. In this study, the health belief model consists of "perceived susceptibility", "perceived seriousness", "perceived barrier", "perceived salience", and "perceived benefit". The questionnaire for the children was composed of 37 items, and the questionnaire for the mother was composed of 40 items. Data were analyzed by frequency, ${\chi}^2-test$, ANOVA, Pearson's Correlation, and multiple regression analysis by a SAS program. The results of this study were summarized as follows ; 1. The first hypothesis that the experimental group would have more change in the frequency of brushing per week than that of control group was accepted(t=3.817, p=0.000). Mean tooth brushing scores in the experimental group improved significantly from pre-test to post-test, but in the control group there was no significant improvement in tooth brushing scores. 2. The second hypothesis that the experimental group would have more change in score of dental health behavior than that of control group was accepted(benefit : t=2.804, p=0.006, salience: t=2.608, p=0,010). An evaluation between the experimental group and the control group showed significant change from pre-test to post-test in health behavior scores. 3. The third hypothesis that higher scores of social reinforcement would create more change in the scores of tooth brushing frequency in the experimental group was accepted(${\beta}$=0.169, p=0.000. Multiple regression was used to examine the peer's social reinforcement scores and the relative influence of significant variables in previous ANOVA and Pearson's correlation test on children's frequency of brushing during the post-test. The results of the study indicated that the combination of social reinforcement of peers with variables pertaining to mother and householder were significantly related and effectively improved a child's tooth brushing.

Mountainous areas are 64% in Korea and are allowed to be used by the permission standards of the "Mountainous Districts Management Act". In the act, slope and elevation criteria are defined to regulate the use of vulnerable land parcels to disaster. However, the standards cannot represent topographical variation in a land parcel such as terrain relief. Therefore, the applicability of slope type standard as a permission standard was tested using Catena in this study. Based on the theoretical grounds, two slope types were analyzed as 'risky slope' with disaster risk. The slope types of landslides in Namwon City were analyzed that 'risky slope' types were distributed about 57%. This study analyzed the forestland parcels that could be used when applying the current permission standards and the parcels that were already used in Namwon City. The ratio of the 'risky slope' in the parcels was more than 50%. Therefore, it is necessary to prevent the mountain development in 'risky slope' by establishing permission standard related to slope types. In addition, this study suggested the ratio of 'risky slope' in the parcel for the permission standard for forestland use conversion.

This study covers Namwoneupseong Fortress(南原邑城), Historic Site No. 298, which played a pivotal role in the urban development and military defense history of Namwon during the Joseon Dynasty. From the related historical records, Namwoneupseong Fortress was first constructed during the reign of King Seongjong. Discussion on the extension of Namwoneupseong Fortress, afterwards, was mainly guided by he traces of Yuingweseong Fortress(劉仁軌城). In other words, the original construction of the Fortress was in the original shape of the current Namwoneupseong Fortress, and Yuingweseong Fortress heavily impacted the extension works of Namwoneupseong Fortress. Although some studies covered Namwoneupseong Fortress and its overall construction process, no in-depth study exists on the original Namwoneupseong Fortress and Yuingweseong Fortress. This study covers the overall construction process of Namwoneupseong Fortress. At the same time, we tried to confirm inclusively and objectively the facts related to the relationship between Yuingweseong Fortress and Namwoneupseong Fortress, process and range of the expansion of Namwoneupseong Fortress among others through the location search of the originally built Namwoneupseong Fortress and Yuingweseong Fortress. The study discovered that Yuingweseong Fortress was built in A.D. 660~665 and that Namwoneupseong Fortress, which was built in the early stage of King Seongjong's reign, was extended along the traces of Yuingweseong Fortress towards the southeast. Furthermore, the study confirmed that Namwoneupseong Fortress is consisted of three sections - the section with Namwoneupseong Fortress's original walls preserved, newly constructed section, and the section following Yuingweseong Fortress's traces.

Based on a concept of soundscape, this study aims to investigate Koreans' preference for auditory elements, features, and impressions depending upon the season, and examine how these auditory factors of soundstape and seasons interact with each other and attempt to discover their influence on people's auditory preferences. According to an environmental psychological approach called the caption evaluation method, 45 college students examined the soundscape of Namwon City while racing the streets in four seasons. In order to analyze the interactions between seasons and such auditory factors as elements, features, and impressions, it was conducted the GLM univariate analysis and the NPAR tests for independent samples. The results of the analyses show that there are interactive effects between seasons and auditory factors like elements, features, and impressions and that the auditory factors have an effect on auditory preference. Moreover, as for seasonal preference for auditory elements, it was found that people prefer natural sound in spring, summer, and fall while they prefer social sound in winter. Concerning seasonal preference for auditory features, people place a focus on the behaviors in spring, summer, and winter while they stress the surroundings in autumn, as for seasonal preference for auditory impressions, they make much of sound characteristics in spring and winter but they value the atmosphere of streets in summer and fall. The results of this study can he utilized as useful data in determining which auditory factors among elements, features, and impressions to take into consideration in a soundscape design.

This paper introduces a conservation treatment for silver diadem ornaments with flower design and the types of corrosive chemical compounds. Twelve silver diadem ornaments with flower design from the Baekje period excavated thus far have been classified into four types. This classification is made more specific in this paper. Each of the silver diadem ornaments was compared with one another. The comparison showed that the same production technique had been used for all of them, but they differed in size and thickness. This suggests that only a few pieces were produced whenever needed, rather than many pieces being produced at the same time.
