This study will define the features of the viewpoint that best enables the view of Busan Port from Young-Do. Special focus will be on spatial distribution, the type Busan Port sights that can be experienced from Young-Do, the compositional characteristic of a port landscape and visual characteristic. The results are based on 27 selected viewpoints and are as follows. Firstly, the patterns of the spatial distribution of viewpoints are classified as park, public facility and wayside types. It was found that most viewpoints are located along a wayside. Secondly, the types of Busan Port sights that can be experienced from Young-Do are divided into three kinds: surrounding stand-line type, facing the port and the type of penetrating city. The major type was of penetrating city among the three patterns. The reason for this is that the point of view for Busan Port was changed into a prospect over the sea since city and road sections have been expanding due to the urbanization of Young-Do. Thirdly, the compositional characteristics of the port landscape are divided into three styles: panoramic, corridor, and rooftop. The most frequent type is the rooftop style among the three characteristics. This fact indicates that the picture of Busan Port seen from Young-Do loses continuity of view and that housetops inhibit the sense of distance. Lastly, the visual characteristics of the viewpoint were analyzed. The angles of the declination of the viewpoints are concentrated on the horizontally closed parts. Thirteen points lie between $-3^{\circ}$ and $-1^{\circ}$, and twelve points between $-6^{\circ}$ and $-4^{\circ}$. The visual axes of the depression are two points because sight is interrupted by buildings which are built when the city expands. Two viewpoints for experiencing the optimum landscape of depression should be prepared to ensure continuous preservation of the viewpoints. The sight creates a wide prospect, reaching from 0.2km to 6.4km. It is expected that the results of this study can be used for the landscape plans of port cities including the management and preservation of viewpoints.

This study generated regression models to quantify storage and annual uptake of carbon from five native landscape tree species through a direct harvesting method, and established essential information to estimate carbon reduction effects from urban greenspaces. Tree species for the study included the Chionanthus retusus, Prunus armeniaca, Abies holophylla, Cornus officinalis, and Taxus cuspidata, which are usually planted in cities of middle Korea, but for which no information on carbon reduction is available. Ten tree individuals for each species were sampled reflecting various stem diameter sizes at a given interval. The study measured biomass for each part including the roots of sample trees to compute total carbon storage per tree. The annual carbon uptake per tree was quantified by analyzing the radial growth rates of stem samples at breast height or ground level. Regression models were developed using diameter at breast height (dbh) or ground level (dg) as an independent variable to easily estimate storage and annual uptake of carbon per tree for each species. All the regression models showed high fitness with $r^2$ values of 0.92~0.99. Storage and annual uptake of carbon from a tree with dbh of 10 cm were greatest with C. retusus (20.0 kg and 5.9 kg/yr, respectively), followed by P. armeniaca (17.5 kg and 4.5 kg/yr) and A. holophylla (13.2kg and 1.8 kg/yr) in order. A C. officinalis tree and T. cuspidata tree with dg of 10 cm stored 9.3 and 6.3 kg of carbon and annually sequestered 3.2 and 0.6 kg, respectively. The above-mentioned carbon storage equaled the amount of carbon emitted from gasoline consumption of about 23~35 L for C. retusus, P. armeniaca, and A. holophylla, and 11~16 L for C. officinalis and T. cuspidata. A tree with the diameter size of 10 cm annually offset carbon emissions from gasoline use of about 6~10 L for C. retusus, P. armeniaca, and C. officinalis, and 1~3 L for A. holophylla and T. cuspidata. The study breaks new ground to easily quantify biomass and carbon reduction for the tree species by overcoming difficulties in direct cutting and root digging of urban landscape trees.

This study analyzes the entrepreneurship education phenomena for agri-food entrepreneurs whose main business is the production of agricultural products and the sale of processed products, using the qualitative study Strauss & Corbin(1998)'s evidence theory approach. From the entrepreneur's point of view, I would like to summarize the phenomena that appear in education, and to prepare a theoretical basis for explaining the phenomena. The importance of entrepreneurship education is emphasized to cultivate the ability to develop and provide products tailored to customers. The necessity of education leads to an increase in demand according to the situational awareness of the founders, and the quantitative increase in entrepreneurship education in the agri-food sector is a clear trend. Inevitably, the need for various discussions on systematic and effective entrepreneurship education is raised. For the study, an interview was conducted with preliminary or entrepreneur who have experienced entrepreneurship education in the agri-food sector. As a research method, I use Strauss & Corbin(1998)'s approach and analyze qualitative data using QSR's NVIVO 12 program. Through this study, it was found that contextual and systematic entrepreneurship education in the agri-food sector has the effect of strengthening competitiveness and strengthening sales. There is a need for follow-up management of trainees. Strengthening the competitiveness of start-ups is based on training professional manpower through education and linking regions with cities. Strengthening sales is based on product planning and market development. This study explores entrepreneurship education in the agri-food sector, which has not been actively conducted in the past. Exploratory analysis on the experiences of the founders of agri-food sector as education demanders has an important meaning for understanding the phenomenon of start-up education.

The seasonal variation of bacterial populations in the Korean cattle (Hanwoo) feedlots dispersed in the 20 cities of Gyeongsangbuk-do, Korea, was monitored for two years (2006 and 2007) to provide quantitative criteria for good agricultural management. Outside the feedlots, the average falling bacterial populations of the air were $3{\pm}1$ CFU/$cm^2\cdot15$ min (n=63) in a year. Inside the feedlots, the average falling bacterial populations of the air were $8{\pm}1$ CFU/$cm^2\cdot15$ min (n=63) in the spring, $16{\pm}2$ CFU/$cm^2\cdot15$ min (n=69) in the summer, $7{\pm}2$ CFU/$cm^2\cdot15$ min (n=69) in the autumn, and $6{\pm}1$ CFU/$cm^2\cdot15$ min (n=70) in the winter. Without using the summer data, the average falling bacterial population of the air was $7{\pm}1$ CFU/$cm^2\cdot15$ min, which was not statistically significant (P=0.37). The average bacterial populations in the cattle drinking water of the cattle feedlots were $4,710{\pm}780$ CFU/ml (n=65) in the spring, $10,430{\pm}1170$ CFU/ml (n=65) in the summer, $4,820{\pm}700$ CFU/ml (n=64) in the autumn, and $2,510{\pm}530$ CFU/ml (n=64) in the winter. Without using the summer data, the average bacterial population of the drinking water was $4,000{\pm}400$ CFU/ml, which was statistically significant (P=0.027). The average frequency of Escherichia coli O157 inside the feedlots was 5% (n=65) in the spring, 72% (n=65) in the summer, 67% (n=66) in the autumn, and 29% (n=66) in the winter on the basis of soil samples of the year 2007. The results indicate that most of the Escherichia coli O157 strains distributed in the summer and autumn was disappeared in the spring through the cold weather of the winter.

This study was conducted to investigate current states and management of the protected trees in Gangwon-do. There were 701 protected trees in 42 species designated by 2008, which were distributed at 425 places. Major species were Zelkova serrata(29%), Pinus densiflora(24%), Ulmus davidiana var. japonica(11%), and Ginkgo biloba(5%). The protected trees played various roles in the villages, mostly as sacred trees(43%). The 51% of protected trees were 300 years or more in age, the 53% were more than 20 m in height, and the 57% were more than 300 cm in girth at breast height. The 69% of the protected trees have been designated for protection in 1982 and the rest have been designated by the local cities by 2008. The species number of the protected trees in Youngseo region was greater than that of the Youngdong region. The major species were Zelkova serrata (33%) and Pinus densiflora(17%) in Youngseo region, and were Pinus densiflora (38%) and Zelkova serrata(19%) in Youngdong region. The ratio of native species to exotic species was 33:1 in Youngseo region, and were 25:6 in Youngdong region. The 29% of protected trees were located in the field, 28% in the mountain, and 25% in the villages. The 45% of the ground were covered by herbaceous plants, 39% exposed, and 10% gravel mulch. Most of the protected trees had good growing conditions. The 70% of the protected trees were under good maintenance, and the rest were under undesirable conditions. The soil characteristics of the protected tree areas in Gangwon-do were not much different from those of Korean average. It seemed to be necessary to increase designation of protected trees based on the tradition, history, local value and academic application in Gangwon-do. In addition, it is desirable to suggest plans to utilize and manage protected tree areas for enhancing the value of natural heritages in Gangwon-do.

The purpose of this study was to evaluate nutrition knowledge and utilization of information on fast food of secondary school students in the two biggest cities, Seoul and Busan. Questionnaires were distributed to a total of 1,265 students (645 at 10 middle schools, 620 at 10 high schools). An average rate of correct answers on nutrition knowledge of fast food was 73.4%. General nutrition knowledge on fast food showed high percentage of correct answers, but the knowledge of vitamin and fiber on fast food was of low percentage. The scores of nutrition knowledge, the fast food (ie. chicken, pizza, gimbab, dukbokki, and ramyon) intake group with $'{\geq}1$ time/week' showed significantly (p<0.01) lower scores than those of the group with $'{\leq}1$ time/month'. The groups with higher interest in health and weight control had significantly (p<0.05) higher scores on nutrition knowledge than those of lower interest groups. Only 19.6% of the subjects had the experience of using the nutrition information for selecting fast food, but 66% of them wanted the developments of the internet-sites to provide information on fast food and on the relationship between fast food and health.

The purpose of this study is to examine the chracteristics of the location of Zen Buddhist temples which are the Nine-Mountain Sects of Zen(九山禪門) from feng-shui perspective. A large number of temples have been built for about 1600 years since Buddhism had influenced on Korea. They have been built nationwide in different times by different sects of Buddhism. The pattern of location of Buddhist temples is different according to background of the times (political, economic, cultural aspect) and of tenet(difference in sects of Buddhism) when the temples were built. But the general location of Korean Buddhist temples is in accordance with feng-shui theory. Feng-shui is a traditional geographic thought in China and Korea. It is necessary to understand feng-shui in order to understand Korean landscape and cultural geography. It had given a tremendous impact on Korean landscape through choosing site of cities, settlements, houses, mounments, temples, pagodas, and so on. Before feng-shui was prevailing in Korea, Buddhist temples were mostly built on sacred place which was connected with folk beliefs. In the case of the late Silla Dynasty when Zen Buddhism was prevailing, feng-shui became popular and many. temples were built in accordance with feng-shui. The typical examples are found in the site of Nine-Mountain Sects of Zen temples. The interpretation of geomantic site of Nine-Mountain Sects of Zen temples will show us how feng-shui was applied to and reflected in the Korean peninsula. In Zen Buddhism, feng-shui was applied to the choice of the temple site. Also feng-shui theory was usually used to choose the site of stupa(Budo) where the remains of the founder of sect. In this study, I will interpret the geomantic characteristics of Nine-Mountain Sects of Zen temples. The geomantic interpretations of the temples are as follow. 1. The temples are located at the foot of a hill with surrounding mountains and a watercourse in front. Feng-shui texts often describe it as an ideal site. This geomantic situation is well equipped with natural drainage; protection from cold wind from the north or evil spirits; a good view with open space to the front; protection from unnecessary weather damage; and security and protection from strangers and invaders. 2. The sitting and facing direction of the temples correspond to the oncoming dragon's direction. 3. Many feng-shui texts discuss the types of Sa(surrounding mountains) in detail and morphologically describe them with certain animate and inanimate auspicious objects. In case of Nine-Mountain Sects of Zen temples, the geomantic landscape of these can be compared to auspicious objects. This is morphological marker for the description of configulation features of these temples. 4. Most auspicious places are not perfect, but the shortcomings can be overcome by many means. We can observe modification of landscape for the purpose of fulfilling the geomantic harmony of the temple.

The study find out developmental factors of the liver diseases in 29,531 subject of the healthy adults who diagnosed by using ultrasound at healthcare centers located at 6 cities around the nation. The results are as follows. Based on the result of the study, the liver diseases diagnosed by using ultrasound revealed to show 43.1％ of prevalence, and the occurrence was significantly higher in male(23.3％) than in female (19.8％)(p<0.001). The disease revealed to show highest prevalence rate in regionally, Dae-jeon was found to record the highest prevalence by showing 49.6％ (p<0.001). The order of liver disease prevalence was the highest in Dae-jeon(49.6%),which was followed by Seoul(48.2%), Busan(42.9%), Incheon(36.2%), Daegu(36.2%), Kangju(32.1%)(p<0.001). The order of hepatic disease prevalence was the highest in fatty liver (69.7％), which was followed by intrahepatic cysts (13.2％), intrahepatic calcification (9.6％), intrahepatic hemangioma (4.5％), intrahepatic tumor (1.4％), diffuse liver disease (1.0％),and liver cirrhosis (0.5％) (p<0.001). The liver disease revealed to show highest prevalence rate in 40s and regionally, disease was found to record the highest prevalence from 30s to 50s (p<0.001). The distribution of the liver diseases by sex revealed to show the higher occurrence of the fatty liver and the diffuse liver diseases in male, but the intrahepatic cysts, intrahepatic calcification and intrahepatic tumors were highly distributed in female. In the regional evaluation, the fatty liver was most often found in Busan, and intrahepatic cysts, intrahepatic hemangioma, intrahepatic calcification and intrahepatic tumors were highly found in Dae-jeon and Seoul revealed to show higher occurrence of diffuse liver disease than other regions (p<0.001). The multiple regression analysis for the related factors which affect the prevalence of the liver diseases resulted to show the higher prevalence by age. sex,
