The purpose of this study was to examine visually impaired people's clothing behavior, using a qualitative approach. The results are intended to be used as baseline data to make an instrument that can measure the factors that have an effect on visually impaired people's clothing needs from the perspective of environmental and social relationship contexts. This study was made through in-depth interviews with people with grade-1 visual impairment, and the results were as follows: First, when purchasing clothing, they were accompanied by trusted people, and chose trusted brands and trusted products. They spent as little time as possible, did not try on many clothes, and they preferred colors, designs, and purchase methods that carried as low a risk as possible. Second, they wanted basic product information and simple procedures when purchasing and using clothing products. Third, they were able to manage their own clothes themselves. However, there was insufficient laundry information available. Fourth, the main reason why visually impaired people took care of their appearance was that they wanted to look neat and clean to be respected by others. Based on the study results, it is necessary to provide information on clothing to improve quality of life and welfare and thus ensure visually impaired people’s independence.

The Citrus Leafminer (CLM) larvae creates shallow tunnels in leaves of citrus (orange, mandarins, lemons, grapefruit, etc) and commonly attacks citrus young leaves. They spread almost worldwide (North America, Asia, Australia, etc) and difficult to control by chemicals due to their small size and their behavior of leaf rolling. Due to difficult of managing, our interest is preparing pheromone to control; Z7Z11-16;Al is known as the sex pheromone of this species in Japan. While blending Z7Z11-16;Al and Z7Z11E13-16;Al (3:1 ratio) is known as the pheromone of this insect in North America. Even though commercialized and mass produced already in overseas, there had been almost no report in Korea about synthetic studies and field screening results. The control of the regio-isomers is very important in this kind of pheromone synthesis. Our strategy is the regio-selective Wittig olefination reaction between E-pent-2-enyl(triphenylphsphonium)bromide (phosphonium salt) and the counterpart aldehyde using sodium hexamethyldisilazide (NaHMDS) as a base. All the spectroscopic data (1H, 13C, GC-Mass, etc) are nicely matched with the previously reported values. The field screening in the Jeju island is currently ongoing and will be reported.

The purpose of this study is to observe the effect of elasticity of taping on ankle muscles’activity and endurance after plyometric training that easily causes ankle injury, and provide baseline data for physical therapy intervention methods. The study subjects are 24 male students in their 20s who attend N University in Choongnam. They were divided into three groups; 8 subjects in the elastic taping group, 8 in the non-elastic taping group, and 8 in the non-taping group(control group). They had plyometric training for 6 weeks. After the training, this study measured their maximum voluntary isometric contraction(MVIC) and muscle endurance of the muscles around ankle joint. The experiment result is as follows. After the training, all three groups showed improvement in muscle strength and endurance. The elastic taping group showed insignificant improvement in muscle strength but significant increase in muscle endurance in plantarflexion. In dorsiflexion, both muscle strength and endurance increased significantly. The non-elastic taping group showed insignificant improvement in muscle strength but significant increase in muscle endurance in plantarflexion. Taping during plyometric training had a little or insignificant effect on muscle endurance and strength compared to the non-taping group.

The mushrooms have been used as traditional medicines and food resources in many countries. The objective of this study was to determine antioxidant compounds and to evoluate tyrosinase inhibitory activity of extracts from Hypsizigus marmoreus. The pileus and stipe of Hypsizigus marmoreus were extracted with methanol and water, separately. The methanol extract of Hypsizigus marmoreus were fractioned by hexane, chloroform, ethylacetate and buthanol. The concentrations of total polyphenolics and flavonoids in methanol extracts were investigated by colorimetric methods. The concentrations of total polyphenolics and flavonoids in methanol extract of the pileus was higher than methanol extract of the stipe. The DPPH redical scavenging activity of the pileus extract was also higher than stipe extract in methanol extract. The IC50 of DPPH redical scavenging activity of the pileus and stipe in methanol extract were 18 mg/ml and 1 10 mg/ml, respectively. The IC50 of tyrosinase inhibitory activity of the pileus and stipe in methanol extract were 500 mg/ml and 1,000 mg/ml in methanol extract. These results suggest that Hypsizigus marmoreus can be potentially used as a source of natural antioxidant agent in the cosmetic industry as well as the food, pharmaceutical and medicinal industry.

바다에 기름오염 사고가 발생하면 여러 가지 방제 방법 중 물리적 회수 방법을 우선적으로 사용하고 유처리제는 최후 수단으로 고려하는 경향이 있다. 유처리제는 수중으로 기름이 신속히 분산되도록 하여 해수면으로부터 제거하는 방법이다. 해수면으로부터 신속히 기름을 제거하는데 대한 유처리제의 효용성은 널리 증명되어 왔으나 아직도 대부분의 국가들은 해양환경에 미치는 독성을 우려하여 적극적인 사용을 하지 않고 있는 실정이다. 보고된 자료에 의하면 유처리제 사용 후 수중생물에 대한 독성은 발견되지 않았으며, 유처리제와 혼합된 기름이 기 름 그 자체보다 독성이 더 크게 나타나지 않았다. 멕시코만 기름유출 사고 시 미국 정부와 BP사는 최대한 해안에 기름이 도달하지 않는데 중 점을 두고 해수면뿐만 아니라 수중의 기름에 대해서도 유처리제를 사용하였다.

In order to isolate thermophilic compost-promoting bacteria with high activity of cellulase and xylanase, spent mushroom substrates with sawdust were collected from mushroom cultivation farm, Jinju, Gyeongnam in Korea. Among of the isolates, one strain, designated HJ01 was selected by agar diffusion method. The strain HJ01 was identified as members of the Bacillus subtilis by biochemical characteristics using Bacillus ID kit and VITEK 2 system. Comparative 16S rDNA gene sequence analysis showed that strain HJ01 formed a distinct phylogenetic tree within the genus Bacillus and was most closely related to Bacillus subtilis with 16S rDNA gene sequence similarity of 99.3%. On the basis of its physiological properties, biochemical characteristics and phylogenetic distinctiveness, strain HJ01 was classified within the genus Bacillus, for which the name Bacillus subtilis HJ0 is proposed. The cellulase and xylanase activity of B. subtilis HJ0 was slightly increased according to bacterial population from exponential phase to stationary phase in growth curve for B. subtilis HJ01.

핵연료 운반용 실린더의 재사용을 위한 용기세척공장의 제염공정에 대한 성능을 평가하기 위하여 Na2CO3 + H2O2 혼합용액의 조합을 약간 달리한 2회의 시험을 실행하였다. 각 시험은 모두 일련의 5 단계에 걸쳐 실시되었다. 우라늄 제염의 주 화학종은 Na4UO2(CO3)3 로 식별되었다. 그리고 첫 단계에서의 세척액은 물이었으며, 이 단계에서 50% 이상의 우라늄이 제염되었다. 그 이후로는 단계가 더해 갈수록 우라늄의 제염양은 지수함수적으로 감소하는 경향을 나타내었으며, 화학양론적으로 제거된 우라늄에 비하여 투여된 Na2CO3 의 양은 과다함을 나타내었다. 이러한 결과들에 의하면, 공정최적화를 통하여 Na2CO3 의 투여량 감축, 세척폐액의 감량, 제염단계 축소 등을 꾀할 수 있을 것으로 판단된다.

The objective of this study was to identify the variation of individual phenol content and antioxidant activity in commercial oyster mushrooms and phellinus mushrooms . The total phenol content varied from 3488.2 to 7161.9 g g-1 in oyster mushroom(Pleurotus spp.). The total phenol content varied from 23390.3 to 26878.3 g g-1 in phellinus mushroom, containing about from four times to seven times more than oyster mushrooms. Among the seventy nine oyster mushroom varieties examined, Bupyeongsoyeob had the highest total phenol content and Keunneutari 1 had the lowest total phenol content. Most of king oyster mushroom(Pleurotus eryngii) varieties and ferula oyster mushroom(Pleurotus ferula)had tendency of low total phenol content. EDA(Electron Donating ability) using DPPH varied from 9.3 to 73.6% in according to oyster mushroom varieties. Most of king oyster mushroom had low antioxidant activity. We believe that the content of functional substances like total phenol content and the antioxidant activities in commercial oyster and phellinus mushrooms could be improved and such varieties strengthed might be selected for the utilization of future breeding resources, based from the results of our study.
