The purpose of this study was to survey and analyze the origin story and the legends associated with Yongyudam(龍遊潭, Dragon Creek), its scenic and spatial description in Climbing Writings(遊山記: Yusangi Notes), its geographical and geological features, its surrounding remains and letters chiseled on the rocks through the field study and the study on literatures associated with it so to identify its significance and value and then to ensure justification on preservation of Yongyudam scenic site. Conclusions of this study are as follow. As the traditional scenic place 'Geumdae-Jiri(金臺智異)' representing Hamyang-gun(咸陽郡) depicts Mount Cheonwangbong and 'Yongyudong Village(龍遊洞)', ancient maps and literatures have positioned Yongyudam as the center of Eomcheon-river Creek as well as the representing scenic site of Yongyudong Village. Core images in the spatial awareness of Yongyudam described in our ancestors' Climbing Writings Notes on Jirisan Mount are 'geographical and scenic peculiarity associated with swimming dragons', 'potholes in various shapes and sizes scattered on rocks', 'loud sound generated by swirling from shoals' and 'the scenic metaphor from the dragon legend', which have led scenic features of Yongyudam scenic site. In addition, significant scenic metaphors from legends such as 'Nine Dragons and Ascetic Majeog' and 'Kasaya Fish' as well as 'the Holy Place of Dragon God', the rain calling magic god have descended not only as the very nature of Yongyudam scenic site but also the catalyst deepening its mystic and place nature. On the other hand, Jangguso Place(杖?所, Place of Scholars) in the vicinity of Yongyudam was the place of resting and amusement for scholars from Yeongnam Province, to name a few, Kim Il-son, Cho Sik, Jung Yeo-chang and Kang Dae-su, where they experienced and recognized Jirisan Mount as the scenic living place. Letters Carved on the rocks at Jangguso Place are memorial tributes and monumental signs. Around Yongyudam, there are 3 stairs, letters chiseled on the rocks and the water rock artificially built to collect clean water, which are traditional scenic remains detectable of territoriality as the ritual place. In addition, The letters on the rock at Yongyudong-mun(龍遊洞門) discovered for the first time by this study are the sign promoting Yongyudam as the place of splendid landscape. The laconism, 'It is the Greatest Water in Jirisan Mount(方丈第一山水)' on a rock expresses the pride of Yongyudam as the representing scenic place of Mount Jirisan. Other than those, standing rocks such as Simjindae Rock, Yeong-gwidae Rock and Ganghwadae Rock show the sign that they are used as amusement and gathering places for ancestor scholars, which add significance to Yongyudam. By this study, it was possible to verify that Yongyudam in Mount Jirisan is not simply 'the scenic place in the tangible reality' but also has seamlessly inherited as the traditional scenic attraction spiritualized by overlapped historical and cultural values. Yongyudam, as the combined heritage by itself, shows that it is the product of the place nature as well as unique ensemble of cultural scenic attraction inherited through long history based on natural scenery. It is certain that not only the place value but also geographical, geological, historical and cultural values of Yongyudam are the essence of traditional scenic attraction, which should not be disparaged or damaged by whatever political or economic interests and logics.

Purpose : Every year, there is a remarkable increase in the prevalence of children with excess body fat. The aim of this study is to find a useful screening method in assessing adolescent, obesity and to specify the predictable risk factors that are related to adult cardiovascular disease according to BMI and obesity index. Methods : From July to November in 2001, a total of 2,814(male : female=2,011 : 803) mid to high school students who were in the obesity range according to obesity index(>20%) were evaluated according to height, weight, body mass index(BMI), obesity index, and serum lipid levels. Results : Among the obese students over 20% by obesity index, 86.6% were over the range of 95 percentile by BMI. Among students defined as obese by BMI, 21.0% of males and 21.4% of females students had hypercholesterolemia; by obesity index, the ratio was 20.7% male and 19.0% female. The frequency of hypertriglyceremia in male students was 15.0% in group I(overweight group, 85P97p); in female students 11.8%, 20.7% and 28.2% respectively. Conclusion : In this study, using BMI alone to test the serum lipid level in adolescent obesity had a limit of 10.0-17.0% omission. Therefore using obesity index as a screening method to find the adult cardiovascular disease would rather reduce the omission rate. The risk factor of cardiovascular disease according to BMI was the increasing level of triglyceride in both male and female students. We think that using the obesity index has more rationale rather than BMI in assessing lipid profiles.

In this study, sorghum teas were prepared from Sorghum bicolor L. Moench subjected to different types of milling (no milling (0%), minimum milling (5%), and milling (20%)) and pan-firing times (1 to 10 minutes), and its quality characteristics were investigated. With regards to milling type, total polyphenolic, flavonoid, tannin contents, and antioxidant activities of ethanol extracts from both no milling sorghum and its tea were highest, followed by minimum milling and milling in decreasing order. Crude nitrogen content was highest in milling sorghum and its tea regardless of pan-firing time. With regards to pan-firing time, total polyphenolic, flavonoid, tannin contents, and antioxidant activities of sorghum teas increased with increasing pan-firing time regardless of milling type. The highest DPPH and ABTS radical scavenging activities were observed at a pan-firing time between 7 to 9 minutes. In contrast to ethanol extracts of pan-fried sorghum tea, antioxidant activities, chromaticity, and turbidity of hot water leaching liqueur of sorghum tea were highest in milling sorghum tea, followed by minimum milling and no milling sorghum tea.

This study created hamburger patties by substituting a portion of the meat with sea tangle (Laminaria japonica) powder and/or cooked rice to reduce fat and calories and to add the functional components of the sea tangle. Four types of experimental patties were prepared: Control, L, LI, and LII. L was the patty with sea tangle powder substituted for 2.5% of the meat and LI and LII were patties with cooked rice containing sea tangle powder substituted for 25 or 50% of the meat. In all experimental patties, moisture content increased and crude fat and cholesterol content decreased, pH increased, and malondialdehyde concentration decreased compared to those in the control. The substitutions made the color of the patties darker with dimmed redness and amplified yellowness. The substitutions also made the cooking loss weight and diameter of the patties lessen but that of thickness increased. In the sensory evaluation, symmetry and color of the patties improved significantly by substituting sea tangle powder and/or cooked rice for meat, and no adverse effect on preference for the experimental patties and hamburgers was observed. Therefore, substituting sea tangle and/or cooked rice for a portion of the meat could be used to develop healthier patties without any adverse influence on preference or sensory evaluation.

Purpose: With a remarkable increase in the prevalence of childhood obesity, the prevalence of nonalcoholic fatty liver disease is assumed to be increasing. The aim of this study is to evaluate the prevalence of nonalcoholic fatty liver disease, hyperlipidemia, and glucose intolerance in normal and obese children. Methods: A total of 2,206 elementary students (boys: 1340, girls: 866) were grouped according to obesity index; normal group and obesity group (mild, moderate, severe). Aspartate aminotransferase (AST, SGOT) and alanine aminotransferase (ALT, SGPT) were measured with total cholesterol, triglyceride, and fasting blood glucose. Results: Compared with the 4.6% of elevated aminotransferases in normal group, obese groups showed significantly higher prevalence; 12.1% in mild obesity group, 19.4% in moderate group, and 21.6% in severe group (p<0.0001). The prevalence of hypertriglyceremia was 16.9% in normal weight group, which was significantly lower than obesity group (mild obesity group 30.3%, moderate and severe 37.6%, 38.2% each). In boys, the prevalences of elevated aminotransferases in normal weight and obese groups (mild, moderate, severe) were 6.8%, 18.0%, 23.0%, and 26.0%, respectively (p<0.0001). In girls, those were 2.1%, 5.1%, 12.0%, and 12.6%, respectively (p< 0.0001). The prevalence of hypertriglyceremia was relative to severity of obesity in boys and girls (p<0.0001). Conclusion: The prevalence of elevated serum liver enzymes increased with severity of obesity. For the prevention and treatment of fatty liver and hypertriglycemia, it is important to lower the obesity degree and enforce the education for a weight loss in the student and the parents.

In this study, I examined the relationship between the pattern of Tungp'o (東坡体)'s characters play, Paza(破字) and Nanji(難字), Iruiimyo(異類異名) the Chinese characters play, developed in the Edo period in Japan. I found out the following. First, Nanji and Iruiimyo's method of Chinese character transformation is like Tungp'o(東坡体)'s characters play and Paza(破字), that is to make an analysis of Chinese character. For example, to extend or shorten to character's length, and to increase or reduce the character's size. And, I also found out there is no block type characters play in Nanji and Iruiimyo. Second, I also found that the similarity of the method of Chinese character transformation between the pattern of Tungp'o(東坡体)'s characters play, Paza(破字) and Nanji(難字), Iruiimyo(異類異名). The method of to flip character (180 degrees) and to letting character lie down (90 degrees) is very similar each other. But there is no method to make incline of character (45 degrees) in Nanji and Iruiimyo. Third, I found that the method to extract part of character also exists in Chinese and Japanese characters play. And, I also found that the method to decompose characters in half from the pattern of Tungp'o(東坡体)'s characters play, but I can't find this method from Nanji and Iruiimyo. To decompose characters in half is very like the method of paja. So, we can understand that Nanji and Iruiimyo is located in the middle stage of the pattern of between Tungp'o(東坡体)'s characters play and Paza(破字).

The present study investigated the habitats of Korean fir trees (Abies koreana E. H. Wilson) on Mt. Baekwun (Baekwun-san), determined the current distribution, quantified the contribution of biological and non-biological environmental factors affecting the distribution, derived actual and potential habitats, presented a plan for the establishment of protected areas, applied RCP 8.5 climate change scenario to analyze the effects of climate change on the future distribution of Korean fir trees, and predicted future potential habitats. According to the results of the study, 3,325 Korean fir trees (DBH >= 2.5 cm) inhabited Mt. Baekwun, and their distribution area was approximately 150 ha. Populations of Korean fir trees were confirmed to exist at an altitude of 900 m above sea level and were distributed up to 1,200 m. Based on potential distribution, areas appropriate for habitation by Korean fir trees were analyzed to be 450 ha, three times the current distribution area, with a focus on Sang Peak (Sang-bong), Eokbul Peak (Eokbul-bong), Ddari Peak (Ddari-bong), and Dosol Peak (Dosol-bong). The forest stands near Sang Peak, the main peak, were evaluated as those with the most appropriate potential for the habitation of Korean fir trees, and populations of the trees tended to prefer the northern slope rather than the southern slope. When climate change scenario RCP 8.5 was applied and future potential distribution was analyzed, the habitats were expected to decrease in area to 20 ha by 2050, with a focus on Sang Peak, and areas appropriate for habitation were predicted not to exist by 2080. Judging from such results, as global warming accelerates, the habitats of Korean fir trees are clearly expected to move from lowlands to highlands.

To understand the status of water quality and work out a suitable countermeasures in Seonakdong watershed which has poor agro- environmental condition because of severe point and non-point source pollution by popularized city and near sea, we investigated the pollution sources and water quality from '03 and '05 and the result were mapped with GIS and RS for end-users's convenient comprehense and conjunction of water quality and geological data. The most degraded tributary was Hogeo stream which was affected directly by highly popularized Gimhae city, the main pollution source of the watershed. The pollution of tributaries in watershed increased the T-N of main body that reached over 4 mg/L during dry season. Pyeonggang stream and the lower part of main water way were suffered from high salt contents induced near sea and the EC value of those area were increased to 2.25 dS/m. The delivered loads of T-N and T-P were largest in Joman river as 56% and 61% of total delivered loads 1mm tributaries because of lots of stream flow. When Management mandate for irrigation water in Seonakdong river watershed was mapped for estimating integrated water quality as the basis of classification of EC and T-N contents in water, Hogeo and Shineo catchments were showed the requiring countermeasures none against nutrients hazard and Pyeonggang catchment was the vulnerable zone against nutrients and salts hazard. As the result, Seonakdong watershed had very various status of water quality by characteristics of catchments and countermeasures for improving water quality and crop productivity safely should changed depend on that.

This study aimed to develop the Korean tool of competency to consent to psychiatric treatment and to analyze the reliability and validity of this tool. Also the developed tool's efficiency in determining whether a patient possesses treatment consent competence was checked using the Receiver Operating Characteristic curve and the relevant indices. A total of 193 patients with mental illness, who were hospitalized in a mental hospital or were in community mental health center, participated in this study. We administered a questionnaire consisting of 14 questions concerning understanding, appreciation, reasoning ability, and expression of a choice to the subjects. To investigate the validity of the tool, we conducted the K-MMSE, insight test, estimated IQ, and BPRS. The tool's reliability and usefulness were examined via Cronbach's alpha, ICC, and ROC analysis, and criterion related validation was performed. This tool showed that internal consistency and agreement between raters was relatively high(ICC .80~.98, Cronbach's alpha .56~.83)and the confirmatory factor analysis for constructive validation showed that the tool was valid. Also, estimated IQ, and MMSE were significantly correlated to understanding, appreciation, expression of a choice, and reasoning ability. However, the BPRS did not show significant correlation with any subcompetences. In ROC analysis, full scale cutoff score 18.5 was suggested. Subscale cutoff scores were understanding 4.5, appreciation 8.5, reasoning ability 3.5, and expression of a choice 0.5. These results suggest that this assessment tool is reliable, valid and efficient diagnostically. Finally, limitations and implications of this study were discussed.
