The structuring of Web information supports a strong user side viewpoint that a user wants his/her own needs on snooping a specific Web site. Not only the depth first algorithm or the breadth-first algorithm, but also the Web information is abstracted to a hierarchical structure. A prototype system is suggested in order to visualize and to represent a semantic significance. As a motivating example, the Web test site is suggested and analyzed with respect to several keywords. As a future research, the Web site model should be extended to the whole WWW and an accurate assessment function needs to be devised by which several suggested models should be evaluated.

This study aims to establish a scenario based on the spacing and arrangement of the roadside trees to reduce heat waves and fine dust in cities that occurred during the urbanization process and to quantitatively analyze the degree of reduction. The ENVI-met 5.0.2v model, a micro-climate simulation program, was used to analyze the degree of improvement in the thermal environment and fine dust according to the roadside tree scenario. As a result of temperature analysis according to street tree spacing, the narrower the distance between roadside trees, the lower the temperature during the day as the number of planted trees increased, and a similar pattern was shown regardless of the distance between roadside trees in the morning and evening. In the case of fine dust emitted from the road, the concentration of fine dust increased slightly due to the increase in roadside trees, but the concentration of sidewalks where people walk increased slightly or there was no difference because of blocking fine dust on trees. The temperature according to the arrangement of street trees tended to decrease as the number of planted trees increased as the arrangement increased. However, not only the amount of trees but also the crown projected area was judged to have a significant impact on the temperature reduction because the temperature reduction was greater in the scenario of planting the same amount of trees and widening the interval of arrangement. In terms of the arrangement, the fine dust concentration showed a difference from the results according to the interval, suggesting that the fine dust concentration may change depending on the relationship between the main wind direction and the tree planting direction. By quantitatively analyzing the degree of thermal environment and fine dust improvement caused by roadside trees, this study is expected to promote policies and projects to improve the roadside environment efficiently, such as a basic plan for roadside trees and a project for wind corridor forests.

For the purpose of cultivating landscape plants, the culture soil of briquet ashes and sludge cakes from urban drainages was used as a bed soil. And Taxus cuspidata, syringa vulgaris, Ligstrum obtusifolia and Buxus microphylla were selected as experimental materials on this soil. The comparison of their growth showed the following results. Each plant showed a slight difference in primary growth and two months after planting, there were notable differences between treated and control plots respectively. Syringa vulgaris shoved the highest growth and the next were Ligstrum obtusifolia and Taxus cuspidata in series. Especially Taxus cuspidata showed the lowest quantity of dry weight compared with other plants, and influenced a little by mean temperature and solar radiation. It is expected to get a high effect in landscape planting by using briquet ashes and sludge cakes.

산업헉명 이후 유리와 철의 이용은 넓은 개구부를 지닌 대형공간을 지닌 건축을 가능케 하였고, 1970년대 이후 새로운 건축양식의 추구라는 시대적 요구는 아트리움의 건축적 응용을 확산하게 하였다. 아트리움은 다층건물의 유리로 덮힌 대형공간으로 건물의 중심적이고 내부적인 공공의 공간이다. 대형공간으로서 아트리움의 가장 큰 특징은 넓은 채광창을 통해 실내로 유입되는 태양광에 있다. 넓은 채광창은 사람들에게 시각적인 개방감을 제공하며, 또한 많은 채광량으로 식재에 의한 조경이 가능해 외부공간과 같은 분위기를 연출하면서도 비·바람·추위 등으로부터 보호되는 쾌적한 온열환경을 제공하고 있다.

This study was conducted to investigate the current status of hygiene performance and food preparation/storage condition in restaurants during the summer season in order to evaluate the sanitary management systems in restaurants against climate change. Total 30 restaurants located in Gyeonggi participated in a survey in which they were asked current hygiene performance, food preparation/storage condition, and purchasing practices for 5 food ingredients. As results, regarding the performance degree of respondents on food hygiene management, the average scores of 9 questions were well over 4 points. However, only 6.83% of the respondents claimed that they use sanitizers (chlorine) to disinfect food ingredients. About food storage condition, a high proportion of respondents said that they store food materials in plastic bags or airtight containers following pretreatment and use refrigerator for the storage of pretreated food materials. However, 5.55% and 14.85% of respondents answered that they store pretreated food materials in the kitchen or inside of dining room, respectively. Respondents (21.50%) answered that they store pretreated food materials for more than 6 hours before cooking. Therefore, food materials need to be disinfected properly with sanitizer to remove microbial contamination and stored at refrigerator using closed bags or containers before cooking in order to prevent foodborne disease in restaurants especially during summer season.

Forest vegetation of Noinbong (1,338 m) in Odaesan National Park is classified into mountain forest vegetation. Mountain forest vegetation is subdivided into deciduous broad-leaved forest, mountain valley forest, coniferous forest, subalpine coniferous forest, subalpine deciduous forest, shrub forest, riparian forest, afforestation and other vegetation. Including 196 communities of mountain forest vegetation and 7 communities of other vegetation, the total of 203 communities were researched; mountain forest vegetation classified by physiognomy classification are 62 communities deciduous broad-leaved forest, 85 communities of mountain valley forest, 18 communities of coniferous forests, 3 communities of subalpine coniferous forests, 4 communities of subapine deciduous forests, 2 communities of shrub forests, 1 communities of riparian forests, 21 afforestation and 7 other vegetation. As for the distribution rate for surveyed main communities, Quercus mongolica, Quercus serrata, Quercus variabilis communities account for 54.856 percent of deciduous broad-leaved forest, Fraxinus mandshurica - Cornus controversa community takes up 15.482 percent of mountain valley forest, Pinus densiflora community holds 78.091 percent of mountain coniferous forest holds. In conclusion, minority species consisting of Quercus mongolica, Pinus densiflora, Tilia amurensis, Fraxinus mandshurica, Cornus controversa, Quercus serrata, and Quercus variabilis are distributed as dominant species of the uppermost part in a forest vegetation region in Odaesan National Park. In addition, because of vegetation succession and climate factors, numerous colonies formed by the two species are expected to be replaced by Quercus mongolica, Carpinus laxiflora and Fraxinus mandshurica which are climax species in the area.

This research was performed to estimate the degree of influence of relative light intensity and planting density on the weight growth in the trans-planting bed. The Piuns koraionsis seedlings treated for different degrees of shading on seed bed were planted in transplanting bed. 1. The seedling weight growth under 100% relative light intensity and $6{\times}6$ plot(36 individual) density showed the largest growth and the best growth was found during 26th of May 25 of June. 2. As the relative light intensity decrease and with planting density increased, the weight growth decreased. And the weight growth had a tendency to decrease after 26th of May-25th of June. 3. T/R ratio showed the highest value under 63% relative light intensity and $12{\times}12$ plot (224 individual) of planting density. The highest T/R ratio was found during 26th of July-25th August.
