  • According to Korean's geographical features of Taek Li Ji, the best location for human settlements is on the vicinity of a stream among a stream, an river and a sea, and not far from a ridge. The researcher chose one of best village which is called Yougokmaeul in Bonghwa-Gun, Kyungsang-Do. This village was created a gathering village with the same surname, can be translated as a hen and the front mountain can be seen as a rooster in the view of the shape of geographical features. As it were, the shape of this village and the cultivated land seems to be an egg inside a nest of a parent's chicken in the respect of the analogy of the theory of P'ungsuchiri which is known as Feng Shui in China and geomancy in the western world, and to effect the defensive psychology of the living environment in the terrain inland. This village is the studying place, Suckchunjungsa as the lecturing and studying place for their following students within the Chunghadonchun, the studying Yougok village, and even the ritual place performing ancestral sacrifices and the first incoming ancestor's graves in the same geographical system. The house site of the first incoming resident is surrounded the countian and is located in the front of Backsulryount which is the main mountain through Moonsu-san in the branch mountain of Korean's mountain system. Backsulryoung which is to be seen as the white peak, is symbolized the head of a hen which is to relate to a mysterious turtle in the view of P'ungsuchiri. And the pavilion which is called Chungamjung is sited on the rock of a shape of turtle which is symbolized to live longer. In the section of the mountain and water, Lee Jung Hwan mentioned a living place near the mountain stream is the best residential area and a landscape which is composed by a stream between mountains make a pleasure spirit and a bright feeling and make a refined person. If one can reach in the graceful mountain make a pleasure split and a bright feeling and make a refined person. If one can reach in the graceful mountain half day away, this kind of place must be a best living residential area to live. But this village was structured all in one place. And one of the ideas tangibly reflected in traditional Korean society's view of life and nature is the seclusion based on the Taoism. This kind of a dreamy thoughts make a dream to keep the paradise in our ancestors' mind. This kind of utopia is Chunghadonchun which is structured 5 aspects from the utopian gate near the Samgaesuewon to the village. These 5aspects is expressed by some Confucian thoughts as a small cosmos individually. On the third aspects which is the center among these aspects, the Suckchunjungsa which was made a seclusion place to devoting himself to his studies with refined tastes. The word of Jiju-am, Gangpung-dae, Jaewol-dae and Biryoung-pock are all expressed to cultivate one's moral character and to seek the truth by the Confucius'theory through the nature.

  • This study is intended to revaluate old tree, five of the shot of the Natural Monument and 66 shot trees under protection in the city at present. The study covers distribution, management of usage, investigation and research into various matters relating to the situation of old trees in Pusan. Because 60% of the old trees selected for protection is on private land, citizens have difficulty gaining access to them. Also space for growth is impinged on by various urban facilities. Some trees have problems of growth because the land is covered with cement and asphalt. As regards space for old trees, many places have been destroyed due to the lack of protection fences and the failure to establish a guidance board. Only 40% of the space has been set aside for rest. In these places the establishment of rest areas, benches and handy chairs is needed. And there are 20 holy places where people observe religious ceremonies. As for space security necessary for old trees according to trunk width, the minimum trunk width and availale area needed are more than 1:1.5, but less than 30% have the necessary space. The growth of many old trees is threatended because of the small apace for growth. The prescription of the boundary space is divided between inside and outside. This indicates the domain nature and space rank of the old tree. It can be classified into five forms for research purposes. The elements for prescription of critical space outside are connected with the security of space, and the elements relating to inside space portray the conditions for sensitive growth according to the institution and the ground conditions. The open and closed nature of old tree space has some connection with the relationship between usage and the intimacy of the user. Most of the spaces for old trees can't be used or are difficult to gain access to, so it is necessary to secure enough space for them. The 18 places, despite having easy access, are near farmland, hills or forest. So the intimacy factor is low, and the security of space of the old trees is not generally sufficient. Henceforth, it will be necessary to have security of area for old trees as well as maintenance control to protect them. Also the space should be used as a communal and recreation are in the city. It is the time to construct a landscaped area which people can easily approach, a place with a secure entrance where they can play, rest and converse.

  • This paper focused on providing the groundwork for the development of proper nursing interventions to enhance the quality of life for the elderly by identifying the factors that may affect their health beliefs and behaviors. A survey was conducted on a group of people aged between 60 and 86 years residing in S and K cities from January to March of 2003, who agreed to participate in the research. Data was collected using instruments measuring health beliefs and health behaviors, and was analyzed by using SPSS. The results of this study are as follow. 1) Those in the group were aged between60 and 86 years, and the average age was 66.94 years old. Most of them were living together with their spouses. From the survey, 83.5% replied "above average" on the question regarding their current health condition, whereas, 46.0% mentioned that they had some sort of diseases. 2) Overall average score of the health belief was 516.05, with a mean $3.71{\pm}4.07$. This indicates that the studied group held a high level of health belief, which affects their attitude and intention to lead a healthy life by placing the present life under control in harmony with nature. 3) Overall average score of the health behaviors was 392.24 with a mean $2.82{\pm}.52$. For health purposes, the behaviors that the elderly people were taking were mostly static ones requiring a low level of activity. The analysis showed that they generally were involved in self-trained, individualized health care. Thus, the elderly place a higher priority on regular dietary behaviors than on physical activity. 4) The correlation between health belief, a cognitive aspect on health, and health behaviors, a behavioral aspect showed a very high linear relationship (r=.520, p<.000). Consequently, it is found that those who have higher cognitive health belief are involved in higher level of behavioral health practice. These findings concluded that the Korean elderly have good health beliefs, well controlling their minds and being harmonious with nature. Health behaviors that they are engaged in are mostly static, requiring low level activity, while they place higher priority on regular dietary habits and conducting self-trained individualized health care. Important factor affecting their health beliefs and health behaviors was found to be their health practice. Since higher health belief is highly related with good health behaviors, development of health activity programs is in need as a means for an efficient health improvement, where motivating environment may be established to enhance the health belief of the elderly and to satisfy individual values.

  • Antenatal care is zoomed toward3 assisting the Individual to achieve safe and wholesome state of health during pregnancy. Nature of fear is assumed to be rooted to complex interaction between past experiences, human relationship and present state of health, however. specific relationship between fear and the variables have not yet been ascertained. This study is designed to investigate the nature of fear of pregnancy, and the correlation between fear and the personal and environmental variables such as personal characteristics past experiences. and psycho-social factors. During the period from October 23 to November 5, 215 pregnant and 104 non-pregnant women of similar chronological are group residing in Seoul were interviewed according to check-list by random General anxiety test, general personality test and test for fear of pregnancy, family according to specific variables such as past experiences of Pregnancy and childbirth, structure of family, family relationship and month of pregnancy was done to the group of pregnant women. To non-pregnant group, general anxiety test was performed to compare with pregnant group. Results of the study are as follows; 1. Hypothesis 1; Degree of general anxiety will be higher e pregnant women compared to that of non-pregnant women. There is no significant difference between the general anxiety of pregnant women and that of non-pregnant women. Therefore, hypothesis I is rejected. 2. Hypothesis 2: Fear of pregnancy and general anxiety will be correlated with personality factors. Through test for fear of pregnancy and general anxiety, a meager contra-correlation between fear and only two personal factors (R and E factor) is revealed but there is no significant correlation between fear and other personal factors (A.S. and T factor). Degree of fear of pregnancy tends to b: higher in the group with low personality factors; responsibility and emotional stability expect the correlation between ascendancy, sociability, and confidence-inferiority. non-significant. Through general anxiety test, level of general anxiety tends to be higher in the group. with low personality factors; responsibility. emotional stability, and confidence except ascendency and sociability, non-significant. Hypothesis 2 is partially supported. 3. Hypothesis 3; General anxiety and fear of pregnancy will be correlated with the past experience-ol pregnancy, and child-birth experience. Though general anxiety test and test for fear of pregnancy, non-significant difference is revealed by P〉.05 level Hypothesis 3 is rejected. 4. Hypothesis 4: General anxiety and fear of pregnancy will be correlated with the month at pregnancy will be correlated with the month of pregnancy. Through tests of general anxiety and fear, significant correlation is revealed degree of fear by-P〈.05 level (CR=1.98) and level of general anxiety by P〈.005 level (CR=3. 11) is higher in the earlier stage of pregnancy. Hypothesis 4 is supported. 5. Hypothesis 5, 6, 7; General anxiety and fear of pregnancy will be correlated with socio-economic status, family structure, and family relationship. Through general anxiety test and tear of pregnancy test, non-significant is revealed by P〉.05 level. Hypothesis 3.6.7 are rejected. Conclusion and recommendation Level of general: anxiety and degree of fear of pregnancy is shown not to be correlated with variables of past experiencers of pregnancy and child-birth. and family factors except the month of - pregnancy. Personal characteristics are shown to be partially contra-correlated meagerly with genera anxiety and fear of pregnancy. This study revealed contrasted results, in regard to presence of correlation between general anxiety and fear of pregnancy to other thesis. In this context. further studies under controlled environment is recommended.

  • The usual definition of and urban resort was a place vastly different from places of daily life such as a theme park or other tourist destination. At the same time, revival of the combination of usual and unusual spaces, in a way like the mixed "Hare"(Special occasion of public event) and "Ke"(Daily life) spaces of communities of old Japan, is part of the idea of urban resorts. And they are places, which start by making a comfortable urban environment for citizens, providing a daily life full of culture and promoting a city′s identity to visitors. if we think about the kinds of structural elements of urban resorts, the usual elements include community, local culture and industry, while the unusual elements include symbols, festivities and interaction. Kobe Wing Stadium is a venue for the 2002 FIFA World Cup hosted by Korea and Japan. The city will build the stadium, but after construction management will be given over to private enterprise, hoping to utilize that sector′s business know how. A competition was held to determine the private executor who would be entrusted with the planning, design, construction and management of the project, considering the conditions of the area, the stadium′s relationship to it and local revitalization. The competition was won by a private enterprise (Kobe Steel Obayashi Group). The them of "Creation of a Sports Community Park" grapples with the large issue of the facility′s relationship with the community. American geographer Yi-fu Tuan coined the word "topophilia" to indicate love of a place. No other word could better describe the desired urban resort nature of the stadium. From this historical perspective it seems that stadiums have great potential as urban resorts. The factor that will determine their success is the attitude of citizens toward them, in short whether they develop topophilia for them or not. We examined the urban resort nature of Kobe Wing Stadium. Regarding daily life, we saw the attempts to revive the local community, the possibility of deepening the local culture and the weakened state of local industry. As a place that is for more than daily life, we saw the certainty of the stadium′s symbolism, its potential as a place for festivities and the test it will face as a space for interaction. Even though several issues are left for future resolution, evaluating Kobe Wing Stadium through these elements of an urban resort, it is clearly founded in the daily life of the community while providing a venue for "Hare"occasions. Fulfilling the roles of an urban resort, it provides many opportunities for local residents to enjoy their and gives visitors a reason to come repeatedly.

  • The metasedimentary rocks together with various granitoids are the main constituents in Taebaeksan gneiss complex, northern Yeongnam Massif. Chemical compositions of sedimentary rocks may reflect the nature of the provenance and could be crucial for understanding the evolution of early continental crust. Previous workers have suggested that the provenance and tectonic studies based on the geochemistry of sediments are applicable to the Precambrian samples. In this study we analyzed the major, trace and REE elements of metasedimentary rocks to understand their provenance and tectonic setting during sedimentation. The overall geochemical characteristics of metasedimentary rocks are similar to those of average shale of the post-Archean. Major element chemistry indicates mature and sorted nature of the sediments. The degree of weathering in the source rocks the is not uniform, as inferred from a large scatter in chemical indices of weathering (CIW). The immobile trace elements such as Th, Sc, and REE can be used to discriminate various sedimentary processes. The Th/sc ratios (0.9 - 4.4) are larger than those of the upper crust and average shale, suggesting that the felsic source predominates. The contents of Ni and Cr and the variations in the ratio of compatible to incompatible elements are similar to the average post-Archean shale. Uniform chondrite-normalized REE pattern with the LREE enrichment (LaN/SmN = 4.9 ${\pm}$ 0.4) and slight negative Eu anomalies (Eu/Eu$\^$*/ = 0.7 ${\pm}$ 0.1) also support this observation. The presence of negative Eu anomaly indicates that intracrustal igneous processes involving plagioclase separation have affected the provenance rocks. The LREE enrichment implies the major role of felsic rocks in source rocks. The eNd (1.9 Ga) values of metasediment rocks vary from 9.4 to 6.7, corresponding to TDM of 2.9 - 2.7 Ga. On the other hand, the 147Sm/144Nd ratios are 0.1079 - 0.1101, corresponding to typical tettigenous sediments. The geochemical features of metasedimentary rocks such as high abundances of large ion lithophile elements, high ratios of Th/Sc and La/Sm, commonly high Th/U ratios, negative Eu anomalies, and negative eNd, suggest a provenance consisting virtually entirely of recycled upper continental crust in passive margin environment. Tectonic discrimination diagrams based upon major element compositions also support this suggestion. In conjunction with igneous activity and metamorphism in the convergent margin setting at 1.8 - 1. 9 Ga, the transition from passive margin to active margin characterize the Paleoproterozoic crustal evolution in northern Yeongnam Massif.
