The goal of this study was to assess the effect of a group exercise program on cognitive function of elderly people. Subjects were chosen to be elders with dementia having minor to moderate degrees of cognitive function. Study was started out by randomly dividing the 16 subjects into two groups, each with 8 people; the group exercise group and the control group. The group exercise group performed 8 weeks of group exercise program and general physiotherapy while the control group only performed general physiotherapy. Cognitive function was measured by Korean version mini-mental state examination. The study group's attention and calculation statistically significantly improved but the control group saw no statistically significant change. The group exercise program affected improvement in cognitive function of elderly people with dementia and in particular, was effective for enhancing their attention and calculation.

The purpose of this study was to analysis of the effect of proprioceptor training and vestibular organ training for balance ability. The subjects was consist of two different subjects group, proprioceptor training group and vestibular organ training group. Proprioceptor training group consisted of 10 subjects and vestibular organ training group consisted of 10 subjects. Training was performed 3 times per week, 30 minutes per day, for 3 weeks. Balance ability analysis was performed using Romberg's one leg standing test and BT4 when opened eyes and closed eyes. The analysis results were as follows. There was no significant differences in balance after the training in both groups when they opened their eyes(p<.05). But there was significant differences in balance after the training in both groups when they closed their eyes(p<.05). And there was no significant difference in balance after the training between the proprioceptor training group and the vestibular organ training group when they closed their eyes(p<.05). Given the above results, proprioceptor training and vestibular organ training enhanced balance but there was no significant difference between the two methods.

The purpose of this study is to observe how balance exercise on an unstable platform and on a stable platform affects balance ability. The subjects were 35 adults in their 20s and were randomly assigned to a stable platform group and an unstable platform group. They performed balance exercise three times per week for six weeks. Balance exercise introduced by previous research was modified and complemented for use in this study. Balance ability of the subjects was measured through center of pressure(COP) area, medial-lateral displacement, and anterior-posterior displacement using a portable balance platform BT4. There was significant difference in the COP area between the unstable platform exercise group and the stable platform exercise group. In comparison in differences between the unstable platform exercise group and the stable platform exercise group after the exercise, there was significant difference in anteriorposterior movement. Therefore, exercise on an unstable platform is more effective than exercise on a stable platform in strengthening balance ability.

The fact that flip-flops, one of many different types of unstable shoes, are light and relatively easy to put on, accounts for their popularity among people. But because flip-flops rely heavily on the support of a single thong between your first and second toes, they impose a huge amount of pressure onto lower leg. Thus in the following experiment we tried to examine the different effects of flip-flops and running shoes in terms of their effect on muscle activity and fatigue of tibialis anterior and gastrocnemius during walking. In order to measure an electromyogram we used Free EMG system. 10 men and 10 women in running shoes ran on treadmills for 15 minutes at 4.8km/h, 2 days later the same experiment was carried out, but this time, in flip-flops. p value turned out to be greater than .05 and thus there was no considerable difference between the effects of flip-flops and running shoes on muscle activity and fatigue during walking. Therefore we conclude that despite the fact that flip-flops are considered unstable, their effects on muscle activity and fatigue of tibialis anterior and gastrocnemius are negligible.

The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study's subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

Porcine Circovirus Type2 (PCV2), a single-stranded DNA virus associated with Postweaning multisystemic wasting syndrome(PMWS) of swine, has two major open reading frames, ORF1 and ORF2. The genomic size and molecular weight of ORF2 is respectively 699bp, 28kDa. ORF2 encodes the capsid protein (structural protein) that has type-specific epitopes and is very immunogenic and associated with the induction of neutralizing antibodies, suggesting its potential use in diagnostic assays as well as vaccine development. For efficient production of the capsid proteins, we expressed the PCV2 ORF2 gene with baculovirus in the insect cells. In this study, PCV2 ORF2 was appropriately ligated into the baculovirus transfer vector, pBacPAK9 and pB9-Acpol19-110-EK. Sf21 cells were transfected with a mixture of the purified recombinant transfer vector and bAcGOZA. We generated and purified recombinant viruses containing PCV2 ORF2, and named rAc-B9-PCV2ORF2 and rAc-B9-19-110-EK-PCV2ORF2, respectively. Expression levels of capsid fusion proteins with a partial polyhedrin region of AcNPV more increased than recombinant proteins from non-fusion expressed. Also, expression efficiency increased over time and differed at MOI. As a results, fusion expression of porcine circovirus type2 ORF2 using baculovirus could be utilized as an alternative expression method to produce recombinant antigen against PCV2 infection and is worthy of further investigation.

The purpose of this study was to comparatively analyze the active stability of shoulder joints according to the frequency of overhead motions, such as serving and spiking, engaged in by female professional volleyball athletes who play different positions, and to provide the results as the basic data for developing exercise programs to prevent shoulder joint injuries. The subjects of this study were 50 Korean female professional volleyball players and positions were as follows: left and right attackers, centers, setters, and liberos. The external rotation and internal rotation muscle strength and muscle strength ratios of the dominant and non-dominant arms of all subjects were measured using Biodex. The results of this study are as follows: Frist, no significant differences were found in the internal and external rotation muscle strength of the dominant and non-dominant arms between positions. Second, for the shoulder joint muscle strength ratio of the dominant arm, by position, the setter showed significantly greater stability compared to the other positions. Third, for the shoulder joint muscle strength ratio of the non-dominant arm, by position, no significant difference in stability between positions was found. Fourth, it was found that the dominant arm had significantly greater instability of the shoulder joint than the non-dominant arm for attackers and centers, but no significant difference was found for setters and liberos. This study comparatively analyzed the muscle strength ratios of the external/internal rotations and dominant/non-dominant arms, which can determine the stability of the shoulder joints between female professional volleyball playing positions that engage in jumps and spikes using only the dominant hand and positions that do not.

This study aims to reveal how EA affects BAX and NF-kB involved in cell deaths from global ischemia, and to do this, observes the changes of BAX and NF-kB caused by EA application after transient global ischemia. The experimental method is to give rise to global ischemia and apply EA to 27 SD rats with the particulars of being six-week-old, male, around-300 gram-weighing, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 EA group(n=9), L14 EA group(n=9), no-treatment GI group(n=9), and then observe their changes of BAX and NF-kB at the time lapse of 6 hours, 9 hours and 12 hours after ischemia, using western blotting. The numerical decrease of BAX expression at the time lapse of 9 hours after EA application, though not statistically significant, was observed in GV20 EA group and L14 EA group, and the NF-kB expression appeared statistically significant decrease in GV20 EA group and L14 EA group, but the expression was higher in the group with EA application. Therefore, EA application at the early phase of global ischemia is considered to affect BAX and NF-kB and play a positive role in decreasing apoptosis and cell deaths by inflammation.

Since physical therapy was first introduced in Korea, it has been 50 years past and Korean physical therapy has made rapid progress. However, history or educational system of Korean physical therapy is still not known worldwide. Now, for Korean physical therapy to go beyond Asia and leap toward the world, endless studies, efforts and publicity are required. Korean physical therapy first began by missionaries dispatched from other countries like America and Canada with Korean War, which occurred in 1950. After the War, Korean Physical Therapy is devel˗ oped very fast. Korean Physical Therapy Association was founded in October 1, 1965 and many physical therapist were discharged. Korea became a full member of World Confederation of Physical Therapy(WCPT) in 1974, and held the 2nd Asia Pacific Confederation of Physical Therapy assembly in 1984 and WCPT assembly in 2005. Today, in 2010, licensed physical therapists are about 35,000 and there are physical therapy departments in 74 universities, and 17 uni˗ versities have master's or doctor's degree courses. And there are many academic journals(more than 10) related to physical therapy that are published. Many Korean physical therapists are working at various countries like America or Australia, and are acknowledged with excellent treatment technology and academic studies. This thesis aims to shed new light to the history and educational system reorganization of Korean phys˗ ical therapy and introduce it to the world, and establish the historical foundation to develop Korean physical therapy into the international level.

In organic agriculture, various cover-crops have been used to control weeds. In this study, we have investigated the effect of Vicia tetrasperma (L.) Schred. (Eolchigiwandu) which is native to on major insect pests of pepper. Redpepper seedlings at 8 leaves stage were transplanted in 20th May 2009 into experimental field located in the farm of the department of agricultural biology, Suwon, Korea. A cover-crop cultivation plot was compared with a control plot mulched by black plastic-film. Density of aphids and damaged fruits by oriental tobacco budworm, Helicoverpa assulta, were surveyed ten times from 21 days after transplanting (DAT) to 82 DAT. Fifty and forty pepper plants were sampled to count the density of aphids and damaged fruits by oriental tobacco budworm per a plant, respectively. In current study, three aphid species namely, cotton aphid, Aphis gossypii, green peach aphid, Myzus persicae, potato aphid, Macrosiphum euphorbiae were collected. Overally, the density of aphids on pepper in the control plot was higher than the cover-crop plot. Especially, aphid density increased up to 67.44±26.8 in early stage of control plot, whereas aphid was not found in cover-crop plot. The rate of fruit damage by oriental tobacco budworm was significantly higher in the cover-crop plot than the control plot in early stage of pepper, however damaged fruit rate of pepper in the control plot was significantly higher since the middle of July.

The devastating insect pests of the tomato (Lycopersicon esculentum) were surveyed in environmentally friendly (no-pesticide and organic) greenhouses located in the provinces of Gyeonggi, Gyeongsang, Gangwon, Chungcheong and Jeju. Whitefly, leaf miner, aphid and moth were recorded as the major pests in these surveys. Among them, whitefly was the most serious pest of greenhouse cultivated tomato and major species was Trialeurodes vaporariorum. The population densities of T. vaporariorum was 0~36 nymph per leaf. Population of moths Spodoptera litura were the highest in summer season. Population of the whitefly was considered to be influenced by the previous cultural methods. Farmers in organic cultivation, used insect natural enemy, commercial EFAM (Environment Friendly Agricultural Material), yellow sticky trap or home made pesticides. Commercial microbial pesticides were applied to evaluate their insecticidal activities against whitefly. The results revealed that microbial pesticides exhibited 65.3 to 100% whitefly nymph mortality. Further, pesticidal activities of Cooking Oil and Yolk (COY), plant extracts and neem oil were evaluated against other tomato pests as well.

Gudul has been used since it was invented, and will be used continuously. But recently, we used rarely. One of the this reason is unequally floor temperature in Gudle because the distribution of heating air is not constant. So flow field in Gudul must be known for uniform temperature in floor. Recently, many fluid engineer have been performed the numerical analysis for the understanding of thermal and flow field based on the development of CFD(Computational Fluid Dynamics). In this paper, to find out the variation of temporal temperature in floor of traditional Gudle, we have performed numerical analysis. Initial temperature in floor is 20 t:' after 880 seconds later, maximum temperature become 2i.Oi t:'. ihour later, maximum temperature in floor become 34.5 t:' because continuously increase from 880 seconds.

Background : Amaranthus is a cosmopolitan genus of annual or short-lived perennial plants. Some amaranth species are cultivated as leaf vegetables, pseudocereals, and ornamental plants. Most of the species from Amaranthus are summer annual weeds and are commonly referred to as pigweed. Approximately 60 species are recognized, with inflorescences and foliage ranging from purple and red to green or gold. Members of this genus share many characteristics and uses with members of the closely related genus Celosia. Amaranthus shows a wide variety of morphological diversity among and even within certain species. This study was conducted to evaluate the growth characteristics and grain yield of Amaranthus under subalpine area(altitude 510m) Methods and Results : Six resources(GR-1∼6) were tested in this experiment. Its seedlings were sown at 21. March. and raised for 27 days in nursery bed. The days after sowing for emerging 80% seedlings was 14∼18 days and No. of leaves was 4.5∼5.2 ea./plant. Plant height of GR-4 was highest at 15.2㎝ in nursery period. These seedlings transplanted at 19. April in the planting density of 80×30㎝. The range of heading date was 25. May∼7. June. GR-1, 2 showed more early heading at 25. May but heading date of GR-6 was 7. June. The Flowering date of Amaranthus cultivated in subalpine area was 20∼28. June. Plant height at flowering time of GR-4 was significantly high at 152.7㎝ comparison with 95.2㎝ of GR-1 but No. of branches in GR-4 was lowest at 7.5 ea/plant. The length of ears was shortest 28.8 ㎝ in GR-5 compared 41.0㎝ of GR-4. Grain yield of Amaranthus harvested at 8. July showed significantly difference according to gene resources and the highest yield of grain was 556.8㎏ in GR-1 Conclusion : The growth and ripening characteristics of Amaranthus tricolor showed many difference under subalpine cultivation according to gene resources. The predictable grain yield of Amaranthus under subalpine cultivation was 240.0∼556.8㎏/10a according to gene resources and their cultivation period demanded 80 days.

The blastocyst should initiate the dynamic changes in morphology and gene expression during hatching and implantation. Blastocyst morphogenesis includes two major events as the formation of blastocoel cavity for lineage differentiation into trophectoderm and inner cell mass, and the blastocyst hatching for implantation. However, there is little known about the relation of dynamic morphogenesis in blastocyst with hatching and implantation potential. In this study, we investigated effects of the dynamic morphogenesis in blastocyst on hatching and implantation potential by outgrowth assay. The cumulative time between each stages was calculated and analyzed. The feature of contraction was evaluated as follows: the number of contractions and the period of circumference was measured. The percentage of reduction during contraction was classified as weak when it was less than 20% and as strong when 20% or more. Compared to embryos of hatching group, embryos of non-hatching group were significantly delayed time at the compacted morula stage by 375.3 min (p<0.05) and at the early blastocyst stage by 650.1 min (p<0.01), respectively. Compared to blastocysts of outgrowth group, blastocysts of non-outgrowth group were significantly delayed at the compacted morula by 404.0 min (p<0.01) and at the early blastocyst stage by 535.4 min (p<0.01), respectively. There is no significant difference in the feature of contraction between hatching and non-hatching groups. However, blastocyst of outgrowth group showed more number of weak contraction and less number of strong contractions, compared with blastocysts of non-outgrowth group (p<0.01). Period of circumference was not significantly different in hatching and outgrowth process. These results suggested that time of blastocoel formation and number of weak contraction in blastocysts were closely related to hatching and outgrowth potential. Dynamic changes of blastocyst formation and contraction could be useful markers to select embryos for predicting the success implantation and pregnancy in human ART program.

Cereal seeds, sorghum, foxtail millet, hog millet, adlay, and corn are traditionally used as health assistant as well as energy supplying food in Korea. While beneficial phytochemicals to human have revealed in cereals, the information on peptides from cereals is far less accumulated than major reserve protein. Here, we analyzed peptide profiles using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF MS) in cereal seeds for construction of peptide information and attempted to develop peptide biomarkers for cereal identification. To optimize the analysis condition of SELDI-TOF MS, the effect of dilution factor on binding affinity to protein chips was tested using CM10 and Q10 arrays. Peptide clusters were significantly different at the level of 0.01 p-value. Peak spectra were the most stable in 1:50 of dilution factor in both chip arrays. Numbers of detected peak of 5 cereal seeds were 131 in CM10 and 74 in Q10 array. Each cereal was grouped as a cluster and well discriminated into different cluster in the level of 0.01 p-value. Numbers of potentially identified peptide biomarkers are 11, 13, 9, 5 and 12 in sorghum, foxtail millet, hog millet, adlay and corn, respectively. This study demonstrates that each cereal seed have own distinguishable specific peptides although their function are not identified yet in this study. In addition, the proteomic profiling using SELDI-TOF MS techniques could be a useful and powerful tool to discover peptide biomarker for discrimination and assess crop species, especially under 20 kDa.
