To estimate the effects of environmental noise on inhabitants' life in an apartment area at Taejon, noise levels and traffic volume of major roads were measured. 203 housewives were surveyed by questionaires including general factors, noise related factors and three items of life effects: subjective evaluations on the general environment, annoyance, and life disturbance due to environmental noise. At the boundary adjacent to the road with more traffic volume, noise level was higher; according to the time, the amount of noise level was in the morning, in the evening, at noon, and at night in order. Most of boundary noise levels were higher than those of recommended standard environmental noise levels in a residential area. The boundary noise level showed a very significant linear relationship with traffic volume of near roads. Noise level difference in the apartments adjacent to three roads was ranged 2.4~6.7dB between in windows open and close state. The apartments adjacent to 9 lane or 6 lane-road, which were protected by noise prevention wall and 20m or more distance from the roads, showed higher noise level at middle floors and high floors than those of low floors; but the buildings adjacent to 4 lane-road, with no protection, showed higher noise level at low and middle floors than those of high floors. Among 203 housewives, 120(59.1%) participated in this study, and 86(73.2%) of them answered that the most serious environmental noise was traffic noise from near roads. Comparing traffic noise levels with those of before-migration, 67.0% participants found the environmental noise became louder. Fifty eight(49.5%) of the participants wanted noise protection wall and 15(25.9%) of them were willing to charge the fee. Less perception on the present noise comparing to those before-migration, less traffic volume, and lower noise levels in the apartments were related to higher scores of self-evaluation on the environment. Higher susceptibility on the present noise, areas with more traffic volume, higher boundary noise levels, and higher noise levels showed higher scores of annoyance on environmental noise and life disturbance. Considering above all things, it was suggested that traffic noise in this area was the major problem of environmental noise, and its' effect was so serious that inhabitants needed some preventive measures for better life quality.

Through the rapid economic growth, modern society have achieved the industrialization but needed to respond to climate change and low-carbon green growth on a scale of urban area. Many studies about the low-carbon city and the green city are on going, but most of them are not integrated but go along in each area(construction, transportation, energy, etc) In this paper, we surveyed the current status of researches about information system to design low-carbon city or green city, and define the method to integrate the outcomes from the each area. As a result integrated model of 'Low-carbon Urban Planning integrated System' in the paper, Individual system is developed by way of C/S form because web system raised problems for data load in analysis. The integrated system was decided to develop by way of Web form, and integrated system was developed by can use the analysed DB in the individual system. We expect this study can help future researches to develop more economical and efficient integrated information system model to design the low-carbon city and the green city. 현대사회가 산업화 되고 고도성장을 이룩하며 자연환경이 훼손됨에 따라 기후변화 대응 및 저탄소 녹색성장을 위한 도시차원의 구체적인 실천대안의 필요성이 증대되고 있다. 국내에서 많은 저탄소도시 및 녹색도시 관련 연구가 진행 중에 있으나 대부분의 관련 연구들에서는 저탄소도시 혹은 녹색도시 구축을 위한 연구를 진행함에 있어 건축, 교통, 에너지 등 각 분야별로 연구를 진행하고 있기에 각 분야별 연구 결과들이 통합적으로 이용되지 않고 있다. 본 논문에서는 이러한 문제점을 해결하기 위하여 저탄소도시 혹은 녹색도시를 위한 시스템을 구축하는 관련 연구들의 현황을 조사하고, 각 분야별로 도출된 결과물을 통합적으로 이용할 수 있는 방안을 정의하고자 한다. 논문에서 정의된 '탄소저감 도시계획 통합시스템'의 통합 모델로서 각 개별 시스템을 분석 시 데이터 로드 등에 대한 문제로 인하여 C/S 시스템으로 개발하고, 통합 시스템에 분석된 DB를 조회/활용할 수 있도록 개발하며, 통합 시스템은 Web으로 개발하는 방향으로 결정하였다. 본 연구 결과를 바탕으로 차후 연구개발 사업들에서는 경제적이고 효율적인 통합 모델이 도출될 수 있을 것이며, 현장에서 실제로 각 개발 성과물들이 활용될 수 있을 것이다.

아세틸렌과 수소기체를 원료기체로 하고 육불화황을 첨가기체로 하여 열화학 기상 증착하에서 탄소코일을 합성하였다. 이 때 산화실리콘 기판위의 니켈막을 탄소코일 성장의 촉매로 사용하였다. 성장된 탄소코일의 생성밀도, 형상, 기하구조 등을 수소 플라즈마 전처리의 유무에 따라 조사하였다. 상대적으로 짧은 시간(1분)의 수소 플라즈마 전처리는 탄소 마이크로 코일을 우세하게 성장시켰다. 긴 시간(30분)동안의 수소플라즈마 전처리는 탄소마이크로 성장 축을 따라 수많은 탄소 나노코일이 들어붙어 있는 특이한 구조를 보였다. 이 특이한 구조는 매우 작은 니켈 촉매의 알갱이를 효과적으로 지지할 수 있는 촉매 지지대로서의 역할을 할 수 있을 것으로 예견되었다. Carbon coils could be synthesized using $C_2H_2/H_2$ as source gases and $SF_6$ as an incorporated additive gas under thermal chemical vapor deposition system. The Ni layer on the $SiO_2$ substrate was used as a catalyst for the formation of the carbon coils. The characteristics (formation densities, morphologies, and geometries) of the as-grown carbon coils on the substrate with or without the $H_2$ plasma pretreatment process were investigated. By the relatively short time (1 minute) $H_2$ plasma pretreatment on the Ni catalyst layered-substrate prior to the carbon coils synthesis reaction, the dominant formation of the carbon microcoils on the substrate could be achieved. After the relatively long time (30 minutes) $H_2$ plasma pretreatment process, on the other hand, we could obtain the noble-shaped geometrical nanostructures, namely the formation of the numerous carbon nanocoils along the growth of the carbon microcoils. This noble-shaped geometrical nanostructure seemed to play a promising role as the good catalyst support for holding the very tiny Ni catalyst grains.

On this paper, we propose SOSL(Self-Organized Supervised Learning) and it's architecture SOSL is hybrid type neural network. It consists of several CBP (Component Back Propagation) neural networks, and a modified PCA neural networks. CBP neural networks perform supervised learning procedure in parallel to clustered and complex input patterns. Modified PCA networks perform it's learning in order to transform dimensions of original input patterns to lower dimensions by clustering and local projection. Proposed SOSL can effectively apply to neural network learning with large input patterns results in huge networks size.

식물근의 추출물질이 종자발아 및 유식물의 생장에 미치는 영향

박찬호,Chan-Ho Park 한국작물학회 1968 Korean journal of crop science Vol.- No.4

This study aimed at contributing to the improvement of cropping systems after finding out the effects of excrements and components of crop root influence on other crops as well as themselves. The following forage crops suitable for our country were selected for the present study. Aqueous extracts of fresh roots, aqueous extracts of rotting roots and aqueous solutions of excrements of red clover, orchard grass and brome grass were studied for the effects influencing the germination and growth of seedlings of red clover, ladino clover, lespedeza, soybean, orchard grass, Italian ryegrass, brome grass, barley, wheat, sorghum, corn and Hog-millet. In view of the possibility that the organic acid might be closely related to the excrements and components of crop root connected with soil sickness, the acid components of three species of roots were analysed by paper chromatography and gas chromatography method. The following results were obtained: 1. Effects of Aqueous Extracts of Fresh Roots : Aqueous extracts of red clover: The extracts inhibited the growth of seedlings of the ladino clover and lespedeza and also inhibited the development of most crops except that of sorghum among the Graminaceae. Aqueous extracts of orchard grass: The extracts promoted the seedlings growth of red clover and soybean, while it inhibited the germination and growth of orchard grass. There were no noticeable effects influencing other crops while it inhibited the growth of barley and Hog-millet. Aqueous extracts of brome grass: There was no effect on Italian ryegrass but there was an inhibiting effect on the other crops. 2. Effects of Aqueous Extracts of Rotting Roots : Aqueous extracts of red clover: The extracts promoted the seedling growth of red clover. But it reflected the inhibiting effects on other crops except sorghum. Aqueous extracts of orchard grass: The extracts promoted the growth of red clover, ladino clover, soybean and sorghun, while it inhibited the germination and rooting of barley and Hog-millet. Aqueous extracts of brome grass: The extracts gave the promotive effects to the growth of red clover, soybean and sorghum, but caused inhibiting effects on orchard grass, brome grass, barley and Hog-millet. 3. Effects of Aqueous Solutions of Excrements : The aqueous solution of excrements of red clover reflected the inhibition effects to the growth of Graminaceae, while the aqueous solutions of excrements of orchard grass and Italian ryegrass caused the promotive effects on the growth of red clover. 4. Results of Organic Acid Analysis : The oxalic acid, citric acid, tartaric acid, malonic acid, malic acid and succinic acid were included in the roots of red clover as unvolatile organic acid, and in the orchard grass and brome grass there were included the oxalic acid, citric acid, tartaric acid and malic acid. And formic acid was confirmed in the red clover, orchard grass and brome grass as volatile organic acid. In consideration of the results mentioned in above the effects of excrements and components of roots found in this studies may be summarized as follows. 1) The red clover generally gave a disadvantageous effect on the Graminaceae. Such trend was considered chiefly caused by the presence of many organic acids, namely oxalic, citric, tartaric, malonic, malic, succinic and formic acid. 2) The orchard grass generally gave an advantageous effect on the Leguminosae. This may be due to a few kinds of organic acid contained in the root, namely oxalic, citric, tartaric, malic and formic acid. Furthermore a certain of promotive materials for growth was noted. 3) As long as the root of brome grass are not rotten, it gave a disadvantageous effect on the Leguminosae and Graminaceae. This may be due to the fact that several unidentified volatile organic acid were also included besides the confirmed organic acid, namely oxalic, citric, tartaric, malic and formic acid. 5. Effects of Components in Roots to th 작물근의 분비물질이나 함유물질이 그 작물 자체에 나 또는 다른 작물에 미치는 영향을 구명하여 작무작촌방식 개선에 기여하고자 본연구를 하였다. 재료와 방법은 우리 나라에 적합한 사료작물중에서 레드클로우버, 옹처드그라스 및 브로움그라스의 생근즙액, 부패근즙액, 수경폐액을 채취하여 레드클로우버, 라디노클로우버, 매듭풀, 콩, 오오처드그라스, 이탈리안라이그라스, 브르움그라스, 보리, 밀, 수수, 옥수수 및 기장 등의 종자발아 및 생장에 미치는 영향을 조사하였다. 그리고, 식물근의 분비물질이나 함유물질중 기지현상과 관계가 깊은 것은 유기산일 것이라는 견해하에 이들 3개 재료작물의 근에서 유기산을 분석하였다. 본 실험 결과는 다음과 같다.

Background: The purpose of this study was to examine the effects of a multi-modal exercise program for patients with chronic low back with respect to pain intensity, trunk muscle strength and Oswestry disability index. Methods: Thirty patients with chronic low back pain were recruited and divided equally into two groups. The multi-modal training program comprised a series of exercises such as warm-up, stabilization exercises, stretching, endurance exercises, and cool down whereas the control group performed only stabilization exercises. The both group spent an equal amount of time performing 60 minutes per day, three times per week, for five weeks. Results: The experimental group demonstrated statistically significant improvements in range of motion, trunk muscle strength, the visual analogue scale, and the Oswestry Disability Index (p<.05). Intergroup comparison showed a statistically significant difference in the range of motion of the lumbar spine and the degree of disability in the experimental group. Muscle strength and pain were statistically significant in both groups. Conclusion: The multi-modal exercise program is effective for patients with chronic low back pain, as it reduces lower back pain, increases trunk muscles strength, and decrease the potential for becoming disabled.
