The purpose of this study was to find out the common characteristics of eating behaviors of the long-lived elderly in order to offer the basic data for establishing dietary guidelines for a long and healthy life for the general population. The subjects were three-hundred elderly people over age 85 living in Kyungpook Sung-ju who have no problems in daily living. The general characteristics, nutrition knowledge and attitudes, meal patterns, and food preferences of the subjects were surveyed by individual intervies. The levels of the nutrition knowledge of the subjects were very low(average score ; 4.3) and the correlation coefficient between their nutrition knowledge and attitude score was also low(r=0.323, p=0.000). Most of the subjects(93%) had a regular meal pattern consuming three meals a day. The major staple food was rice mixed with other grains(75%) and the number of side dishes was mostly under four(99%). A majority(73%) had no habit of overeating and 51% of the subjects were taking snacks besides regular meals. Thirty one percent of the subjects had drinking habits and 80% of the drinking subjects had over 40 years of drinking history. The most common frequencies for intakes of various food groups were ; more than once a day(95%) for vegetables ; 2∼3 times a week(74%) for green and orange color vegetables ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2∼3 times a week(49%) for milk ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2-3 times a week(49%) for milk ; 2-3 times a week(85%) for seaweeds and 2-3 times a week(81%) for foods cooked with oil. The most preferred foods by the subjects were white rice(staple foods), soybean paste soup(soups), beef and eggs(meats and eggs), yellow croaker and hair tail(fish and shellfish), yoghurt(milk and milk products), all vegetables except carrot(vegetables), and watermelon(fruits). The popular food preparation methods included mixing with seasonings and the most preferred taste was sweet. The results showed that the eating pattern of long-lived elderly was characterized by regularity, simplicity, and no overeating.

In recently, the low impact development(LID) is discussed at various fields being related to urban stormwater, non-point source pollution, and quality of life. It is understood as an integrated development tool to induce sustainable development with various value-social, economic, and aesthetic. As concerning the development of waterfront area, the low impact development is interested in environmental planning. But the planning process and factors are not considered in precedent research. This study has two purposes. The one is to understand the planning process and factors of low impact development from literature review. The other is to apply the planning factors using case study and to know the effect of low impact development as the simulation plan. The simulation plan is based on some landuse planning. It is divided into the setting the region for environmental protection and the function of public facilities, spatial planning for enlarging permeable area, and spatial planning for circulation of water. The simulation model uses the LIDMOD2. The 14 planning factors of low impact development is applied to case region. And the effect is about 7~10 percent in reduction of nonpoint source pollution and surface runoff.

Objectives: The purpose of this study was to examine factors associated with the self-rated health status of the elderly and whether these factors were different from younger adults. Methods: An interview survey was conducted on non-institutionalized adults in Wonju City, Korea. Determinants of self-rated health status were identified and compared between individuals aged 19 to 64 years and those aged 65 years and over, using an ordered logistic regression conducted separately on these two groups. Participants were 1,685 younger adults and 188 elderly people. Self-rated health status was measured along a continuous scale from 0 to 100 (0 for the worst and 100 for the best they could imagine) and then binned into 11 categories. Results: Self-rated health status of the elderly in Wonju was associated with household income, education, bereavement, adequate sleep, daily and social life being affected by poor health status, mobility, and anxiety and depression. Household income, adequate sleep, and participation in social activities were significant only in the elderly, while some factors associated with the self-rated health status of younger adults, such as rural dwelling, regular exercise, living alone, and skipping breakfast were not significant in the elderly. Conclusion: In order to improve the health of the elderly in Wonju City, it would be necessary to develop programs addressing those specific needs of the elderly and to integrate them effectively in the Healthy City projects.

The late $19^{th}$ and early $20^{th}$ centuries of Korea were the times when the Confucianism (牲理學) ideology was shaken heavily under the influences of modernism and capitalism by Western and Japanese military and political-economic forces. Under such circumstances, alteration of clothing was much influenced by ideologies than changes in social structure or technological advance. In this study, an ideology was defined as "the force which drives people into a particular social order". Ideologies were postulated as an ongoing process of socialization with dialectic features rather than being a static state. Comparative analyses on conflict structures and different clothing patterns symbolizing the ideologies of the Ruling (支配) and the Opposition (對抗) were conducted. Investigating dresses as representations of ideologies is to reconsider the notion of dichotomous confrontation between the conservatives (守舊派) and the progressives (開化派) and a recognition of Koreans' passively accepting modernity during the Japanese occupation. This may also have contributed to enlightening Koreans about modernization. Here are the results. First, the theoretical review found that ideologies were represented by not only symbols of discourse, but also dresses, and that dresses embodied both physical and conceptual systems presenting differences between ideologies and their natures, Second, during the late 19th century Korea, conflict between conservatives' Hanbok (韓服) and progressives' Western suits (洋服) was found. Moderate progressives showed their identity by "Colored Clothing" (深色衣), and radical progressives by black suits with short hair (黑衣斷髮) or by western suits (洋服). The ultimate goal of both parties was a "Modern Nation". With these efforts, pale jade green coats and traditional hats symbolizing the nobleman class was eliminated within 30 years from 1880 to 1910, and then simple robes and short hair emerged. However, the powerful Japanese army had taken over the hegemony of East Asia, and Korea was sharply divided into modernization and pro-Japanese camps. Third, during the time of Japanese colonial rule, the dress codes having set by the modernization policies during the time of enlightenment were abandoned and colonial uniforms for the colonial system was meticulously introduced. During this period, Western or Japanese-style uniforms were the symbol of the ruling ideology. In the mean time, Hanbok, particularly "White Clothing (白衣)", emerged as a representation of the opposition ideology. However, due to Japan's coercive power and strong zeal for "Great orient (大東亞)", white clothing remained as a mere symbol. Meanwhile, Reformists (實力養成論者) movement toward improving quality of life followed a similar path of the Japanese policies and was eventually incorporated into the ruling ideology. Fourth, dresses as representations of ruling ideologies were enforced by organizational powers, such as organizations and laws, and binding policies, and changes in such dresses were more significant when the ruling ideologies were stronger. Clothing of the opposition ideology was expressed as an aggregation of public consciousness. During the period, the subjects of ruling ideology and the objects who were granted modernization benefits were different although their drives for colored clothing with short hair (色衣斷髮) for modernization were similar.

This research was performed to determine the quality characteristics of cookies made from flour added with 0, 1, 3, and 5% sea mustard (Undaria pinnatifida Suringer) powder. The quality characteristics of the cookies, including pH and density of the dough, moisture content, spread factor, loss rate, leavening rate, color, mineral content, texture properties, and sensory properties, were estimated. The density of the dough, water content, spread factor, loss rate, leavening rate, a and b values of color scale, and mineral content of the cookies significantly increased while those of pH, L value, and hardness decreased with higher content of sea mustard powder. With the exception of flavor, consumer acceptability scores in terms of appearance, taste, texture, and overall preference for cookies made from 3% sea mustard powder significantly ranked the highest. Taken together, the results of this study suggest that addition of 3% sea mustard powder to flour is effective for increasing the consumer acceptability and functionality of cookies.

The purpose of this study is to demonstrate the positive effects of artificial ground greening on the reduction of carbon dioxide ($CO_2$) which can help improve ecological functions in cities and mitigation of climate change, through quantifying $CO_2$ uptake and evapotranspiration by the process of photosynthesis of some plants. Experiment of $CO_2$ uptake and evapotranspiration was conducted by measurement of $CO_2$ exchange rate using the infrared gas analyzer, for 7 month, growing season from May to November 2009, 2 times a month. The result was as follows; The $CO_2$ uptake quantity per $cm^2$ of Chrysanthemum zawadskii was the highest rate at $21.47{\times}10^{-6}g/cm^2/s$ and Poa pratensis was $16.20g{\times}10^{-6}g/cm^2/s$. The stronger was light of intensity, the higher were $CO_2$ uptake rate of most plants. In quantity of evapotranspiration, Poa pratensis was the highest rate at $8.75{\times}10^{-5}g/cm^2/s$ and Aquilegia buergariana was $8.66{\times}10^{-5}g/cm^2/s$. From this study, it is confirmed that artificial ground greening has capacity of absorption $CO_2$ and effects on improving urban microclimate.

Although the Dreamland site was the only flat amusement park in the northern part of Seoul, the site lost its function as a regional park due to aging and, therefore, was no longer in use. The site is surrounded by currently existing high dense low-story housing blocks and proposed new towns. A renovation plan for Dreamland was raised by the City of Seoul to enhance the quality of the urban environment in the northern part of Seoul. This study articulates the design concepts and strategies of the prizewinning work of the International Design Competition for Gangbuk Large Park. The three key points can be summarized as follows: First, this design proposal tried to find a new possibility for a large mountain park in an urban areas. These days, mountain parks are used limitedly as ordinary living spaces for activities such as a walking, hiking, and physical training. New strategies were sought to reconstruct the sentiment with which our ancestors enjoyed the mountains. Second, this proposal tried to make Dreamland a socially self-sufficient park. We designed a park which generates self-energy and which communicates with the city, not a park which only exists as a green island in a city. Lastly, rain fed paddy fields, a typical Korean vernacular landscape, was a tangible space which represented people's life-styles harmonizing with the nature. Rain fed paddy fields is a design motif which puts the three surrounding mountains together with the site. It is expected that the new design will works as a noted place.

The activity changes and biochemical properties of ${\beta}$-gal in tomato fruits during ripening were investigated. The total activity was increased during ripening and three isoenzymes (${\beta}$-gal I, II and III) were purified through DEAE Sephadex A-50 and Sephadex G-100 column chromatography. The activities of ${\beta}$gal isoenzymes (${\beta}$-gal I, II and III) during ripening were 69.8, 31.8 and 170.0 units in mature green phase, while those were 48.7, 88.4 and 136.8 units in Red phase, respectively. As the ripening proceeded the activities of ${\beta}$-gal I and III were some what decreased but the activity of ${\beta}$-gal II was incresed more than 2.8 fold. The optimum pH of ${\beta}$-gal I, II and III were 3.9, 4.2 and 3.9 and the optimum temperature of those were $60^{\circ}C$, $56^{\circ}C$ and $60^{\circ}C$, respectively. All isoenzymes were stable at pH 3.6~6.0 and lost their activity about 50% when it heated at $55^{\circ}C$ for 5 minute. $Mg^{{+}{+}}$-activated the three isoenzymes but $Ca^{{+}{+}}$ and SDS inhibited about 30~40%. $Hg^{{+}{+}}$ inhibited completely. The km value of ${\beta}$-gal I, II and III was 0.36mM, 0.63mM and 0.45mM, reaction rate was rapidly increased until the concentration of substrate was $6.0{\times}10^{-5}M$.

There is a need in food industry to store minimally processed garlic for long time to have it be used just at the time of demand for final product processing. Optimal modified atmosphere packaging is expected to slow down the quality change extending its storage life. In order to find optimal packaging conditions, plastic films of different gas permeability properties (low density polyethylene (LDPE) $30{\mu}m$, polyolefin $50{\mu}m$ (PD 900), polyolefin $20{\mu}m$ (PD 941)) were used for packaging 400 g of minimally processed garlic. Perforated LDPE packages were prepared as control. The packaged products were stored at $1{\pm}1^{\circ}C$ for 52 days. Package treatments were compared in weight loss, decay, surface color, hardness and soluble solid content. While control package had normal atmosphere of air, LDPE, PD 900 and PD 941 packages attained internal concentration of $O_2$ 4.6% / $CO_2$ 12%, $O_2$ 0.9% / $CO_2$ 21% and $O_2$ 0.5% / $CO_2$ 13% after 45 days, respectively. Control packaging had rapid weight loss with high mold decay and great surface color change in 45 days. In PD 900 film packages of lowest gas permeability, the fresh-cut garlic could be stored without mold decay for 52 days. Except control packaging, there were no significant differences in surface color, hardness and soluble solid content among package treatments.

During a last decade, the introduced traits in commercialized GM crops have been diversified from a simple trait such as herbicide resistance gene or insectresistance gene which are related to the crop production into more complicated traits such as modification of fatty acid or essential amino acid composition, modified coloring pattern of flower. In addition, it was investigated that several other GM crops bearing more refined traits expected to lead next generation are also awaiting for risk assessment (RA) or under field test for the preparation of RA in the near future. These GM crops include abiotic stress resistance including drought or cold, increased biomass, production of bioethanol or diesel, production of pharmaceuticals or functional materials for industrial. In particular, in 2008 and 2009, it was reported that the highest number of GM crops for molecular farming are under developed in laboratory or green house level in all the world. Likewise, in Korea, 171 events from 49 plant species are under developed to introduce several important traits. At present, about 10 events are under field test to select elite lines for RA application. For the first time, herbicide resistance turfgrass developed by Korean research team has been submitted for RA and currently under requested for additional data. Moreover, GM rice resistant to leaf roll (folder) disease is expected as a next event to be submitted for RA application.
