The typical Japanese house has the characteristics of open dwellings to make them cool in the hot and humid summer. And then the traditional town house 'Machiya', being built very closely to each other and walled up both sides, it has taken the open-oriented characteristics in itself. The purpose of this study is to clarify that the open-oriented of traditional 'Machiya' has been succeeded to the new 'Machiya' in the latest. The new 'Machiya' shows the open-oriented, taking the ventilative 'Huki-nuke' space of traditional 'Machiya' as the new spatial formal elements, in the changes such as scale material space organization. The characteristics of 'Huki-nuke' space are represented as follows ; 1. The facade of the traditional 'Machiya', which has taken on a semitransparent qualty, has been generally changed to the closing qualty except for the open parts of shop and garage. This facade of the new 'Machiya' has been taken to be in keeping with the existing town as much as possible. 2. A series of three rooms, composed of shop/living dining kitchen/room from the road, have been dispersed to every floors in a building with a very extensive scale. But this serial and linear type remains as the loosefit space, and the long dwellings of the upper stories are divided by type each dwelling unit. 3. 'Tori-niwa', which is a consecutive and penetrating space, connects the road with the rooms of dwelling and functions as the circulation of man thing energy, The new 'Machiya' changed to the multi-story, the corridor and the stair have been fumed up as the elements in the place of 'Tori-niwa' The 'Huki-nuke' space was locted in the hall, stairwell, living dining kitchen room, and so on. 4. The small court yard 'Tsubo-niwa' and back yard 'Ura-niwa' at the both ends of living spaces would be made a hole in a series of rooms and enclosed by the neighboring 'Machiya'. On the contrary the new 'Machiya' at present takes in the private and closing organization enclosing the innercourt. 5. The open-oriented ${\ulcorner}$In${\lrcorner}$ or ${\ulcorner}$Out${\lrcorner}$ is not brought out because of the delicate spatial formal configuration in the traditional 'Machiya'. But the open-oriented ${\ulcorner}$In${\lrcorner}$, all sides being closed by walls, is well brought out in the new 'Machiya'.

Infection of free-living dinoflagellates by endoparasitic dinoflagellates of the genus Amoebophrya are thought to have significant impacts on host population dynamics and have long been proposed to be a potential biological agent for controlling harmful algal bloom (HAB). To understand the impact of Amoebophrya on particular host species, however, it is necessary to quantify aspects the parasites life cycle. Here we used cultures of Amoebophryahost systems from Jinhae Bay, Korea to determine, parasite generation time, and dinospore survival and infectivity. The proportion of host cells infected by Amoebophrya sp. changed sharply from 5% to 87% with increasing dinospore:host inoculation ratios. In the absence of H. triquetra, most free-living dinospores died within 72 hours and their ability to infect host cells decreased remarkably in a day. The relatively short free-living phase of Amoebophrya suggests that the spread of infections is most likely to occur during seasons of high host abundance, as that is when dinospores have the greatest chance of encountering host cells. Infection of host cells inoculated with dinospores during the day was higher than when inoculated during the night, suggesting that infection rates might be related to environmental light conditions and/or diurnal biological rhythm of host species. Total generation times of parasite strains from a thecate dinoflagellate Heterocapsa triquetra were nearly the same regardless of dinospore:host inoculation ratios, representing 54 ± 0.5 h in a 1:1 ratio and 55 ± 1.2 h in a 20:1 ratio. Dinospore production of Amoebophrya sp. infecting Heterocapsa triquetra was estimated to be 125 dinospores per a strain of Amoebophrya sp. There is a growing need to maintain a variety of host-parasite systems in culture and to examine their autecology under various environmental conditions. Such studies would be very helpful in understanding ecological role of these parasites, their overlooked importance in the flow of material and energy in marine ecosystem, and their practical use as biological control agents applied directly to areas affected by HAB.

This study is attempt to submit a basic material to help the efficient nursing management which supports and to understand the alienation which they percieve social-psychologically and physical aging bringing about the phf·sical powerlessness, to understand the old people in hospitals and in community and should build up their health. The data collection of the study which has been done on Sept. 7 to Sept. 20, 1986 is objected to 300 people of 65 years old of age or more of male and female who are staying at home. Analysis of the Data was done by use of percentage, t-test, ANOVA and Pearson Correlation Coefficients. The results of study are summerized as follows: 1. According to each age group of old people(p= .0008), family living together concreteness (p=.0000), the level of education (p=.0020), how much they are participating in leisure activity (p=.0001), whether they have mate or not (p=.0000), whether they have religion or not (p=.0000), the level of alienation showed difference statistically. Also, according to sex (p=.4315), whether they have income or not (p=.1197), the level of alienation did not show any difference statistically. 2. According to each age group of old people (p=.0000), family living together concreteness (p=.0060), the level of education (p=.0000), sex (p=.0000), whether they have mate or not (p=.0000), whether they have religion or not (p=.0067), whether they have income or not (p=.0000), the level of physical aging showed difference statistically. Also, according to how much they are participating in leisure activity, the level of physical aging did not show any difference statistically (p=4879). 3. The level of alienation and physical aging in old people had positive correlation (r=.5436, p<.001). From the above result, the level of social, psychological alienation and physical aging showed high for the old who had no mate, no religion, low in their educational level, living separately' with the family and for those who do not participate much in the leisure activities, The old people who feel the social, psychological alienation can expedite the physical aging and physical aging can be result from social psychological loneliness and alienation. Therefore, for the successful aging of the old people in the community with these weak points, we should provide them with physical and emotional, psycho-logical support and care in the basis of understanding in socialization process and the character of the physical functional change.

In coastal area of Inchon, dredging and the disposal of dredged material for sea-wall construction and reclamation have increased in recent years. These activities may impact the benthic environment and result in changes in benthic communities, but little information is available on the extent and direction of these changes. We investigated whether there have been changes in the dominant macrobenthic species and benthic community over the last decade, and explored the relationship between environmental variables and spatial patterns of macrobenthic community structure. We sampled macrobenthos and recorded environmental variables in the coastal habitats of Inchon in March and June 2004. In total, 212 macrobenthic species were recorded during this study, predominately crustaceans $(34{\%})$, mollusks $(32{\%})$ and polychaetes $(21{\%})$. The mean density of macrobenthos was $1,393\;ind./m^{2}$.The most abundant species was Amphioplus japonicus $(20.5{\%})$, followed by Heteromastus filiformis $(14.4{\%})$, Theora fragilis $(8.2{\%})$ and Ampharete sp. $(4.0{\%})$. Over the past decade the dominant macrobenthic species in this area shifted. Multivariate analysis (multidimensional scaling) revealed significant differences in community structure among three regions: the middle part of the sampling area (B), site 8 (C) and other sites (A). Mean density varied significantly among the three regions, but no differences in the number of species and diversity (H') were observed. The distribution of the macrobenthic community was affected by environmental variables such as percentage sand content and sediment kurtosis. Species that were important in different areas included A. japonicus in region A, Raeta puchella in region B and T. fragilis in region C. The important species in regions B and C were filter-feeding bivalves, and the abundance of these species may be related to the increase in percentage sand content. We suggest that the sediment composition (percentage sand content) may be an important factor in determining the dominant species and structure of the macrobenthic communities in coastal Inchon. Long-term monitoring programs are necessary to understand ongoing changes in the benthic communities of this area.

Cotton is an important fiber crop, and its seeds are used as feed for dairy cattle. Crop biotechnology has been used to improve agronomic traits and quality in the agricultural industry. The frequent unintentional release of LM cotton into the environment in South Korea is attributed to the increased application of living modified (LM) cotton in food, feed, and processing industries. To identify and monitor the LM cotton, a method for detecting the approved LM cotton in South Korea is required. In this study, we developed a method for the simultaneous detection of four LM cotton varieties, MON757, MON88702, COT67B, and GHB811. The genetic information of each LM event was obtained from the European Commission-Joint Research Centre and Animal and Plant Quarantine Agency. We designed event-specific primers to develop a multiplex PCR method for LM cotton and confirmed the specific amplification. Using specificity assay, random reference material(RM) mixture analysis and limit of detection(LOD), we verified the accuracy and specificity of the multiplex PCR method. Our results demonstrate that the method enabled the detection of each event and validation of the specificity using other LM RMs. The efficiency of multiplex PCR was further verified using a random RM mixture. Based on the LOD, the method identified 25 ng of template DNA in a single reaction. In summary, we developed a multiplex PCR method for simultaneous detection of four LM cotton varieties, for possible application in LM volunteer analysis.

The most common conception of a work of art is as a unique object. In conservation the prevalent notion of authenticity is based on physical integrity, this guides judgements about loss. For the majority of traditional art objects, minimising change to the physical work means minimising loss, where loss is understood as compromising the (physical) integrity of a unique object, and this forms the focus of conservation. Fundamental to conservators' approach to the conservation of contemporary art is the notion that the artist's intent should guide conservators' practice. Since most of the artists creating installation art are living, it is possible to interview them about the details of the installation, attitudes to changing technology, parameters of acceptable change and their views about what aspects of the installation are essential to preserve. Conservation is no longer focused on intervening to repair the art object but has become concerned with documentation and determining what change is acceptable and managing those changes. In order to accurately install works in the future it is necessary to broaden our focus to include elements of an installation that affect the viewer's experience. This might mean documenting the space, the acoustics, the balance of the different channels of sound, the light levels and the way one enters and leaves the installation. These are as important as the more tangible or material elements in the conservation of the work. It is also necessary to work with industry and specialists outside the field of conservation to develop new skills to preserve and manage new types of objects in our care. We can also document the less tangible details of an installation such as the light levels, the character of the sound etc. This is a new area of conservation and as a profession our understanding and knowledge will deepen with time. All of these strategies work together to help to limit the risk of not being able to accurately install these works in the future. Deciding what can be changed and how to best care for any element of an installation will depend on its meaning and role. For both contemporary and traditional objects such decisions are documented by conservators and although the focus of the conservator may have moved away from the material object, the approach is still rooted in traditional notions of collection care.

The purpose of this study was to find out the purchasing practices and consumer's needs for pet dog apparel to provide useful information for the manufacture of pet dog's apparel. Data were obtained from 203 consumers who have purchased dog apparel(55 male, 148 female). 57.9% of them were 20-30 years old, 27.9% were living in houses, 54.3% were apartment residents. The kinds of dog included were Shihtzu, Martise, and Yorkshireterrier, and 2/3 of the respondents own a single dog, the remainder have at least two dogs. The most important factor to consider when purchasing dog apparel was size, followed by comfort, design, and materials in that order, Most of the apparel was purchased with convenience as the primary consideration, and the average price was 10-30 thousands won, and the items were purchased at pet beauty shops or specialty shops. For materials, it showed that the majority preferred cotton or a cotton mixture which was woven or woven with knit. The survey revealed that the main purposes for the apparel were, in order, to protect the dog from cold weather and direct sunlight, to be good looks and to memorialize a special day. Consumers put the apparel on their dogs 1-3 times per week, on average, and also when they went out for a walk. They were satisfied with the design, color and quality of the material now on the market, but unsatisfied with size and price. They have a preference for cute, but simple designs and a functional style. The respondents wanted to have material that was mild or neutral, stain-resistant, and something that would repel insects.

The subjects of ttis study were middle-aged women in their 40s$\sim$50s and older women aged 60 and over who were living in Seoul and Kyonggi-do, Korea. Through studying the participants' responses to the questions regarding the attributes of image preference in terms of the levels of satisfaction and importance, the target consumers' demand has been studied. And, they are applied to a QFD Matrix, to find out the relationship between the attributes of product quality and the guidelines of clothing design. For this study, clothing image preference is categorized as three types: fashionable and urbane image, elegant and formal image, comfortable and active image. It has also been found that middle-aged and older women think the clothing that projects fashionable and urbane image needs more improvement that those for other images. To review demands for the clothing image preference attribute of formal suits for middle-aged and older women, the priority of these attributes through QFD Matrix that shows the relationship between the attributes and dress elements emphasized by designers has been examined. In reflecting clothing image preference by consumers for their formal two-piece suits, the most important design elements related to material in order of importance were material type, style, thickness and texture, and those related to color were the number of colors used and coloring type.

The aim of the present study was to investigate and analyze a tendency of the Philippines furniture which are not well-known in Korean market yet, but have been emerging as an OEM base, through the Manila FAME 2012. The study was conducted by visiting some furniture companies in Philippines for the active understanding regarding the current status of the Philippines furniture, in consideration of the material, functional and structural aspects of the goods which were exhibited on the Manila FAME 2012. The methods of the investigation were to research the related literatures concerned and materials had been collected over the internet, to visit the Manila FAME 2012 at work and finally to visit furniture companies in Philippines. Manila FAME has been based on the DTI (DTI: Department of Trade and Industry) through CITEM (CITEM: The Center for International Trade Mission and Expositions) since 1983. The exhibition whichincludes various sorts from furniture, traditional artifacts, leisure goods, gifts, jewelry and clothes is becoming such a potent force by integrating three exhibitions such as Manila Now, CEBUNEXT and Bijoux Cebu, what all had been held before the world economic downturn. The features of the Philippines furniture shown on the Manila FAME are as follows: First, they are focusing on the maximum of function to the exclusion of the decoration and they were mostly made of various kinds of mahogany like jambilina, acacia, bamboo, wisteria and Manila hemp growing up in the Philippines indeed and finally there were a lot of the simple designs of the curved line which were exactly the material nature of the wisteria and Manila hemp.

There was a study for biological characteristics, except for physico-chemical and mineralogical properties, on the natural bentonite that is considered as a buffer material for the high-level radioactive waste disposal site. A bentonite slurry that was prepared from a local 'Gyeongju bentonite' in Korea was incubated in a serum bottle with nutrient media over 1 week and its stepwise change was observed with time. From the activated bentonite in the nutrient media, we can find a certain change of both solid and liquid phases. Some dark and fine sulfides began to be generated from dissolved sulfate solution, and 4 species of sulfate-reducing bacteria (SRB) were identified as living cells in samples that were periodically taken and incubated. These results show that sulfate-reducing (or metal-reducing) bacteria are adhering and existing in the powder of bentonite, suggesting that there may be a potential occurrence of longterm biogeochemical effects in and around the bentonite buffer in underground anoxic environmental conditions.
