With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

The purpose of this study is to identify the characteristics of monuments in the Seoul Foreigners′ cemetery at Yanghwajin, a place where many prominent Christian missionaries and other Christians have been buried near Choltusan. In considering the characteristics of gravestone details, the researcher has divided the details into 4 analysis categories: forms, symbols, epitaphs, and materials. For this research, 281 monuments were selected including 68 of missionaries, 26 of U. S. Army Soldiers, and 13 of teachers. The analysis revealed that there were 26 types of monuments. This includes simple and standardized types like the tablet, headstone, marker, and monolith. These were used more often than other shaped types such as the Cross, obelisk, sculpture, etc. Standardized types made in Korea have been preferred after the 1950s even though the beauty of the gravestones has been degraded. Symbolical decorations related to religious, social, professional or military emblems were also introduced to strengthen their symbolical objectives. Among them, fie Cross was the most predominant Christian symbol and emblem. The families wanted to inscribe epitaphs, the greater part of which originated from the Bible, poems, idioms related to tribute, rest, supplications to deity, love, achievement, to express human sentiment and religious faith. When using materials for making monuments, monument makers have mostly used stone because of its durability. Until the 1950s, various stones had been used to make monuments, for most marble and granite were brought from foreign countries. These were very different from the Korean white marble stone used for many monuments. After the 1950s, the source of stone has been limited to Korean stone, for Korean could make stone monuments that foreigners were agreeable. Especially, a black marble stone called "O-Suk" which means black stone, has been used as a main material. The study identified the following characteristics of monument details in the Seoul foreigners′ cemetery at Yanghwajin. First, Christianity has been applied as the main concept, while symbolizing the homogeneity of religious, family, social, professional or military groups by having the symbolic form, symbol, and epitaph in common. Second, monuments made after the 1950s have been standardized into unattractive and monotonous forms by the limited materials, and so the beauty of the monuments has been degraded.

A microarray dataset is 2-dimensional dataset with a set of genes and a set of conditions. A bicluster is a subset of genes that show similar behavior within a subset of conditions. Genes that show similar behavior can be considered to have same cellular functions. Thus, biclustering algorithm is a useful tool to uncover groups of genes involved in the same cellular process and groups of conditions which take place in this process. We are proposing a polynomial time algorithm to identify functionally highly correlated biclusters. Our algorithm identifies 1) the gene set that has hidden patterns even if the level of noise is high, 2) the multiple, possibly overlapped, and diverse gene sets, 3) gene sets whose functional association is strongly high, and 4) deterministic biclustering results. We validated the level of functional association of our method, and compared with current methods using GO.

The aim of this study was to identify the drinking patterns and needs for nutritional education of male workers. The subjects in this study were 285 male workers in Ulsan City. The average age of the subjects was 41.2 years old, height was 171.8cm, weight was 69.6kg and Body Mass Index(BMI) was $23.6kg/m^2$. The subjects were classified into 3 drinking patterns such as 'normal drinker(ND)', 'excessive drinker(ED)', and 'alcoholic drinker(AD)' diagnosed by NAST (Alcoholism Screening Test of Seoul National Mental Hospital). Each group was 31.6%(ND), 43.2%(ED) and 25.3% (AD). The amount of one time drinking, frequency, kind of alcohol and spending money were significantly different among the groups. 87.8% of ND thought that the self identity of drinking habits was good. But twenty seven percent of AD thought that it was just not bad, one-half of them(51.4%) thought they seemed to have problems and 20.8% of them thought they were serious. 38.9%(AD), 22.8%(ED) and 6.7%(ND) of each group tried to abstain by turn. Reasons of trying to abstain were health problems, disharmony of family and bad influence on the business and job place. The methods of abstaining were to avoid a drinking gathering or to refuse drinking in the party. 70.8% of AD, 59.3% of ED and 40% of ND thought they needed to take an educational program about abstaining. 58.3% of AD, 43.1 % of ED and 31.1 % of ND answered they would join an alcohol program.

Objectives: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. Methods: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. Results: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with family members. Conclusions: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

The objective of this research is to identify and examine the punk hair styles which, with their various, rather vague names, help to describe the twentieth century subordinate culture or subculture and also their place today as one of the mainstream male hair trends. The scope of this research will stretch to include also: North-east and around that areas native Americans'hair styles which, are thought to have strong links with the Punk hair tend. The focus of this research will remain with the so-called Mohican or Mohawk hair styles(collectively referred to as Punk styles), which have originated mainly from native American warrions residing in North-east and South-east region of the United States. This study clarified a few questions in doubt concerning the origin of cockcomb hairstyle. Firstly, the cockcomb hairstyle known to represent punk hairstyle was influenced the American Indian's Roach style. Secondly, since Roach style is referred as Mohawk tribe's hairstyle in some refernces, the view of seeing cockcomb hairstyle as a Mohawk style is considered more persuasive. Thirdly, although Roach style was a usual hairstyle through North-east and South-east region of the United States, the people in South-east region did Roach hair style because of the North-east's influences. Lastly alike the Punkers had several kinds of cockcomb hairstyle. American Indians'Roach style also differed in shape concerning of their regions and their kindred. In addition, the reason why the most common term to refer punk hairstyle became Mohican is considered as that the film 'Last Mohican' has influenced on it. That film can appeal their history and play a good role of mediator to let the public know better about themselves, 'Mohican' naturally became the name of the specific hair style.

Since the accomplishment of industrialization and mechanization, human and the nature have gone farther their own way. Human depending on technology have been increasingly expanding and developing their artificial space and as times go by in such a way, estrangement between the human and nature has resulted in dissatisfaction of human's instinctual desire and devastation of human's living. People, to deal with such challenge, begins taking a look at the nature. In introducing the nature into the modern architecture, a physical natural element is often directly taken into or the shape that could be inferred from the nature is taken. The study was intended to identify the characteristics of the pattern introducing the nature into the modern architecture, as mentioned in the former case, which is summarized as follows, Introduction of the nature contains a variety of functions in the space and it creates the new space by integrating the internal and external space which becomes boundaryless integrated space. The boundary in the building tends to be getting more ambiguous, while the space accommodating the nature serves the interface, playing a role of intermediator for both the internal and external space. It functions the open public place that helps build the natural community among the users but taking the nature into the inner space, and it is used to attempt to change the interior of the building or for ventilation lighting or energy-saving purpose. The spatial meaning was found to have varied depending on pattern of the nature introduced. Such conclusions mentioned hereon is expected to help forecast and understand the forthcoming space accommodating the nature when reviewing the pattern of introducing the nature appeared In modern architecture.

The purpose of this study is to investigate ways to control the wind dispersal of contton-wrapped seeds of such poplars and willows as Poplus alba, P. tomentiglandulosa, P. euramericana, P. deltoides, and Salix pseudo-lasiogyne. These trees are hated by many people because of their seeds blowing all over the place during May. These cottony seeds can be nuisance to various types of outdoor activities, pose safely threat to drivers, become fire hazards during prolonged spring dry spells, and cause many types of health hazards of allergy such as sneezing. rhinitis, asthma, and skin rashes. Four control methods can be used to resolve the problem. First, pruning can be a solution, but it is unsatisfactory in terms of costs and outcome. Second, planting of male trees only can be a solution, but it is hard to identify sexes of saplings. Third, female trees can he replaced with other species. But it requires high costs and takes at least ten years to functionally replace the removed ones. As an alternative to such unsatisfactory control methods, the possibility of applying plant growth regulators has been investigated since 1983. During the pre-test, various concentrations and mixtures of them were either sprayed or injected, but failed to achieve any promising results. But the injection of a mixture made up of 0.75g of 2-chloroethane phosphonic acid with 0.2 mg of GA in 300cc water in the end of March produced premature falling of almost all aments and capsules of treated poplars and willows. It was found that the effect of the injection lasts two years. The results of the main experiment of 1987 can be summarized as follows ; First, the injection of the mixture of 2-chloroethane phosphonic acid and GA increases the premature abscisin of aments and capsules, thus reducing the wind dispersal of the cottony seeds of S. pseudolasiogyne, P. tomentiglandulosa, and P. euramericana 1644.09, 1200.61, and 1485.11 times, respectively, than that of the naural abscisin, It is estimated that the average number of wind-blown seeds reduced are approximatively 6,185,100, 4062,900, and 2,830,670 per tree, respectively. Second, the treatment causes no observable side effects on the growth of the samples tested.

Designing a complex begins with plans to differentiate the archetypical place in accordance with environmental characteristics of the area where target programs and districts are to be located, with which the space reformed with the change and development of the era is established and shaped. In particular, in the area such as our domestic land, some 70% of which is inclined has adopted the design concept that uses slopes with the stream of times and has sought design strategies that consistently interpret and approach slopes. Taegwondo Park, the target of this study, has collected six draft design plans during the design stage with different values and thus strategies of utilizing topographies and spaces differentiated accordingly. Particularly, approaching strategies in accordance with geographical features by designer, the relationship between architecture and external space to be implemented according to the rank, philosophical understanding of architects and design strategies as the concept of iconizing the area carry significant implications as major design strategies explored by this study, through which I was able to identify the possibility of materializing the design strategy for hill lands.
