The aim of this preliminary study was to investigate the effects of virtual reality combined with balance training on upper limb function, balance, and activities of daily living (ADL) in patients with acute stroke. The both groups received conventional rehabilitation for 30 min/days, 5 times a week, for 4 weeks. Additionally, the experimental group received 30 minutes of virtual reality training on unstable surface for each session, while the control group received 30 minutes of virtual reality training without unstable surface. To examine the upper limb function, balance, and ADL, the study used Manual Function Test (MFT), Berg Balance Scale (BBS), and Korean Modified Barthel Index (KMBI), respectively. The both groups showed significant improvements in MFT, BBS, KMBI before and after the intervention. The experimental group showed no significant difference in MFT, BBS, K-MBI after intervention compared with the control group. In the changes of fall risk, the experimental group showed a greater decrease in numbers of fall risk (BBS <45) before and after intervention than the control group. These finding suggest that the virtual reality training combined with balance training may have a better effect on balance improvement than virtual reality training without balance training in post-stroke.

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

Backgrounds: One of the main problems conditioning the outcome of islet transplantation is the ability to separate a sufficient number of viable islets with preserved function. Islet purification is critically affected by all of the isolation stages. Thus, it is necessary to set up the standard isolation method that islets are separate well from acinar without compromising islet yield and viability. Methods: Twenty three adult mongrel dogs were used for the experiment of total pancreatectomy with islet isolation. The islets were properly isolated by a modified Recordi method. The obtained islets were further purified by centrifugation on discontinuous gradients using cell separation system (Model 2991, Cobe, Lakewood Colo). We evaluated islet number (islet equivalent number, 150 um equivalents/kg of recipient body weight, IEq/kg), purity, cell volume, viabilty, recovery rate, and comparison of outcome according to the isolation conditions. Results: 1) The mean of islet numbers before purification were 13543±9431Eq/kg, digestion times were 13.8±2.6 min., digestion temperature was 37.4±0.2℃, purity was 59.7?.0%, viability was 90.0±2.1%, cell volume was 4.7±1.1 mL, islet number after purification were 4064±361 IEq/kg, and recovery rate was 29±2.9%. 2) Isolated islet numbers were different according to the degree of pancreas distension with collagenase, digestion temperature, and digestion time. 3) The best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase. 4) According to multiple regression adjusted by variable factors, the degree of pancreas distension with collagenase and digestion time were independently associated factors for successful islet isolation. Conclusions: In this study, we concluded that the degree of pancreas distension with collagenase and digestion time were independent factors for successful islet isolation and the best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase.

본 연구에서는 한국 및 중국산 감초(Glycyrrhiza uralensis), 그리고 우즈베키스탄산 감초(Glycyrrhiza glabra)를 대상으로 추출용매, 추출온도, 추출시간 등 추출조건별 추출물을 제조하고 이들 추출물들의 추출 수율과 항산화 활성을 비교하여 최적의 추출조건을 선정하였다. 항산화 활성 중 자유 라디칼(1,1-phenyl-2-pic-rylhydrazyl, DPPH) 소거활성은 85% 에탄올로 60 ℃에서 6 h 동안 추출한 조건에서 한국 감초로부터 얻은 추출물이 가장 높은 활성(46.05%)을 나타내었다. 루미놀 발광법을 이용한 추출물들의 총 항산화능 측정 실험과 피부 광노화에 중요한 ¹O₂으로 유도된 세포막 손상에 대한 추출물들의 세포 보호 효과를 측정한 실험 모두에서도 위의 조건에서 가장 높은 항산화 활성을 나타내었다. 특히, 한국 감초는 τ₅₀이 116.4 min으로 비교 물질인(+)-α-tocopherol (28.5 min)보다 약 4 배나 높은 세포 보호 효과를 나타내었으며, 추출 수율은 18.75%로 우즈베키스탄 및 중국 감초보다 각각 1.2 배 및 2.5 배의 추출 수율을 나타내었다. 따라서, 본 연구 결과는 항산화 소재로 화장품에 응용하기 위하여 감초로부터 추출물을 얻기 위한 최적의 조건은 85% 에탄올로 60 ℃에서 6시간 동안 추출하는 것임을 보여주었다. In this work, licorice extracts were prepared using various extraction conditions such as extraction solvent, temperature, and time from Glycyrrhiza uralensis (G. uralensis) produced in Korea and China and Glycyrrhiza glabra (G. glabra) in Uzbekistan. The optimum extraction condition was selected from the extraction yields and antioxidative activities of extracts. Korea licorice extracts showed the highest free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scav-enging activity (46.05%) under the extraction condition of 85% ethanol at 60 ℃ for 6 hours. The prominent ROS (reactive oxygen species) scavenging activity using luminol-dependent chemiluminescence assay and the cellular protective effect against ¹O₂ induced cellular membrane damage were also shown from the extracts obtained from the same condition. Especially, Korea G. uralensis extracts exhibited the higher prominent protective effect (τ₅₀ = 116.4 min) than (+)-α-tocopherol (τ₅₀ = 28.5 min) and the extraction yield of Korea licorice extract was 18.75%, which is 1.2 times and 2.5 times higher than that of Uzbekistan and China, respectively. These results indicate that the extraction condition of 85% ethanol at 60 ℃ for 6 hours is optimal to prepare licorice extracts, which can be applicable as antioxidative cosmetic materials.

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

Since the 1970's, a lot if housing have been constructed to solve the shortage of housing in urban area. Among them, the multi-family housing has located as major housing type in urban area with recently two million housing construction. In 1993, the total number of housing construction was about 690 thousand, among which positioned in 77% of apartment and 31% of detached-housing. Though this policy resulted from housing policy focused on construction & supply, the aspect of maintenance of building has not concerned. In the end, the housing policy which was focused on construction resulted in inefficient living of low housing condition. Therefore, we should take a policy to use the housing resources efficiently with the systematic maintenance. This require to correct the maintenance concerned law, code, maintenance repair technique. With the recurring development of housing construction technique and new material and etc., the maintenance methods should be systematized. For this, it analyzed the deterioration factor and compared our preparations with the foreign code about repair cost, cycle, repair time, repair ratio. This study will use as basic data to set the repair criteria of multi-family housing. These results of this study will provide the systematic and technique preparations, analyzing the factors of building deterioration. And this study will enlarge the life of building and to live the higher housing condition and use the building resources efficiently.
