The purpose of this study was to investigate the effects of strengthening and stretching exercises on forward head angle and static·dynamic balance ability. 21 adults with the forward head posture were participated in this study. Subjects were randomly assigned to strengthening exercise group I(n=11) and stretching exercise group II (n=10) respectively. Each group were underwent six intervention over the period of 2 weeks, each session lasting 30 minutes. During a preliminary examination, forward head angle and static∙dynamic balance were measured, and a post examination was conducted that involved same procedure as preliminary examination. There were significant differences in forward head angle after exercise in both groups. In the strengthening group, center of gravity total sway distances was significantly changed under all conditions. In the stretching group, center of gravity total sway distances was significantly changed when subjects had their eyes open while standing on an foam surface. There were significant changes in center of gravity sway velocities in the strengthening group under all conditions, and the same was true in the stretching group only when the subjects had their eyes open while standing on an foam surface. In the comparison between groups, eyes closed while standing on a firm surface was significantly different. There was a significant difference in dynamic balance of the stretching group when the subjects tilted their bodies forward, and there was a statistically significant difference between groups under the same condition. The results of this study suggest that forward head posture can be corrected through therapeutic exercise, and muscle strengthening exercise more effective in improving static balance of forward head posture more than stretching exercise.

Recently, methods that usea carbon-based filler, a conductive nanomaterial, have been investigated to develop composite fillers containing dielectric materials. In this study, we added geometric changes to a carbon fiber, a typical carbon-based filler material, by differentiating the orientation angle and the number of plies of the fiber. We also studied the electrical and electromagnetic shield characteristics. Based on the orientation angle of 0˚, the orientation angle of the carbon fiber was changed between 0, 15, 30, 45, and 90˚, and 2, 4, and 6 plies were stacked for each orientation angle. The maximum effect was found when the orientation angle was 90˚, which was perpendicular to the electromagnetic wave flow, as compared to 0˚, in which case the electrical resistance was small. Therefore, it is verified that the orientation angle has more of an effect on the electromagnetic interference shield performance than the number of plies.

The centipede Scolopendra subspinipes mutilans has been a medically important arthropod species by using it as a traditional medicine for the treatment of various diseases. In this study, we derived a novel lactoferricin B like peptide (LBLP) from the whole bodies of adult centipedes, S. s. mutilans, and investigated the antifungal effect of LBLP. LBLP exerted an antifungal and fungicidal activity without hemolysis. To investigate the antifungal mechanism of LBLP, a membrane study with propidium iodide was first conducted against Candida albicans. The result showed that LBLP caused fungal membrane permeabilization. The assays of the three dimensional flow cytometric contour plot and membrane potential further showed cell shrinkage and membrane depolarization by the membrane damage. Finally, we confirmed the membrane-active mechanism of LBLP by synthesizing model membranes, calcein and FITC-dextran loaded large unilamellar vesicles. These results showed that the antifungal effect of LBLP on membrane was due to the formation of pores with radii between 0.74 nm and 1.4 nm. In conclusion, this study suggests that LBLP exerts a potent antifungal activity by pore formation in the membrane, eventually leading to fungal cell death.

This study has investigated the effect of isometric contractile force and muscle activity applying sperficial heat according to the time from the biceps brachii muscle. In this study, 20 university students participants without musculoskeletal and neurological disorders. By applying a hot pack 5min, 10min, 20min and 30min respectively. After that measurement are skin temperature, contractile force and muscle activity. Skin temperature of the hot 5 min applied that rapidly changing. Increasing the time it takes to apply a variance has been reduced(p<.001). Isometric contractile force was not statistically significant but highest when applying the hot pack 5 minutes and lowest when applying the hot pack 30 minutes(p<.001). Muscle activity and median frequency was highest when applying the hot pack 5 minutes. To analyze the above results, it was found that isometric contractile force and muscle activity changed according to the applying time. These result lead us to the conclusion that this study will be more evidence for changes in muscle contraction to apply hot pack on clinic.

The purpose of this study is to examine the effects of gait training using functional electrical stimulation on the improvement of hemiplegic patients' functions for balance and gait velocity. The subjects of the experiment were determined to be 10 each hemiplegic patients who had been diagnosed with stroke or brain damage six months or longer earlier assigned to an experimental group and a control group respectively. The subjects were evaluated before the experiment using Tetrax and 10M gait tests, received gait training five times a week for four weeks using functional electrical stimulation and were evaluated after the experiment in the same method as used in the evaluation before the experiment. In order to examine differences between the experimental group that received gait training using functional electrical stimulation and the control group that was treated by functional electrical stimulation and received gait training thereafter, differences between before and after the experiment were analyzed using paired sample t-tests and differences in changes after the experiment between the experimental group and the control group were analyzed using independent sample t-tests in order to compare the two groups with each other. Experimental results showed significant differences in weight bearing, balance and gait velocity between before and after the experiment in the experimental group(p<.05). In the control group, whereas weight bearing and gait velocity did not show any significant difference between before and after the experiment(p>.05), balance showed significant differences(p<.05). Weight bearing, balance and gait velocity change rates showed significant differences between the experimental group and the control group(p<.05). In conclusion, it was indicated that gait training using functional electrical stimulation is effective for enhancing stroke patients' weight bearing rates, balance abilities and gait velocity.

본 시험은 국화에서의 기형화 발생과 DNA 메틸레 이션에 관여하는 S-adenosyl-L-homocysteine hydrolase (SAHH) 유전자 발현과의 관련성을 검토하기 위해 수행 하였다. 스프레이 국화 ‘Lerbin’은 단일후 14일에서 27일 사이에 고온과 장일 조건에서 기형화가 발생되어, 35/20oC 의 고온과 14시간의 장일 처리 할 경우 25/20oC(12 h/ 12 h)에 비해 설상화가 2배 이상 증가하는 양상을 보였다. 스프레이 국화 ‘Lerbin’에서 분리한 전장 cDNA (DgSAHH) 는 크기가 1455 bp로 다른 작물과 90%이상의 높은 상동 성을 나타내었다. 국화의 DgSAHH 유전자 발현은 기형화 발생을 유도하는 고온과 장일 조건에서 크게 감소하였다. 이러한 결과를 통해 국화의 화아 발달에 있어서 DgSAHH 유전자 발현은 온도와 일장의 영향을 받으며, 억제된 이 유전자의 발현이 기형화 발생에 관여할 수 있을 것으로 판단된다.

The purpose of this study was to identify the effects of manipulation on the velocity of cerebral blood flow and level of pain in cervicogeinc headache patients. The velocity of cerebral blood flow of 30 cervicogeinc headache patients(male=15, female=15, age=24.00±3.60) and 33 normal subjects(male=15, female=18, age=23.27±3.00) was compared. The 30 cervicogeinc headache patients were divided into suboccipitalis relaxation group, cervical manipulation group, and placebo group, and each were given different interventions. The velocity of cerebral blood flow and pain level was measured before intervention, and 1, 2, 3 weeks after intervention. The velocity of cerebral blood flow was measured with the Transcranial Doppler(TCD), and pain level was measured with visual analog scale(VAS). Blood flow velocity of middle cerebral artery in cervicogeinc headache patients was slower than those in healthy subjects. Physical therapy intervention did not have significant effect on velocity of cerebral blood flow, but slowly decreased at intervention for pain level increased. The suboccipitalis relaxation group and cervical manipulation group showed significant effect in decreasing pain level compared to the placebo group(p＜.05). Directly applied manipulation therapy in the neck area not only has effect on joint of cervical and soft tissue but also on blood vessels and nerves which pass the neck area, and because of those results of manual therapy seems to help recovery.

The genus Gonioctena Chevrolat is distributed in the Holarctic and Oriental regions, with more than 80 species. Many species of the genus have great similarity in external morphology and coloration, often cause misidentifications. Thus, the shape of the aedeagus is mainly used to distinguish closely related species. Fifty-four species, more than half of the known taxa, occur in northeastern Asia, including 18 species in the Russian Far East, 29 in China, 11 in Korea, and 18 in Japan. Among these, G. gracilicornis Kraatz (type locality: Amur) is widely distributed in Russia, China, Mongolia and Korea. However, extensive investigation on Gonioctena in Korea revealed that the Korean population of G. gracilicornis differs from that of the Russian by the coloration, the puncturation of pronotum, and the shape of aedeagus. The purpose of this study is to describe a new species of Gonioctena that was previously misidentified as G. gracilicornis. A key to Korean Gonioctena, distribution, and host plant are also provided.

The purpose of this study was to determine the effects of heat appli˗ cation on the immune activities of the human body. To exam, further˗ more, the immune effect from the healthy volunteer(male:15, female:15) by monitoring changes of immune substances such as various leukocytes[total white blood cell(WBC), eosinophil, neutrophil, basophil, monocyte, and lymphocyte], a comparative study with warm water immersion(40.8±0.3℃) and infrared(250W) was carried out. The plasma analysis showed that the count of white blood cell, eosinophil, and neutrophil were elevated in warm water immersion- or infrared˗ stimulated group compared with control group. However, the count of basophil was decreased in both warm water immersion- and infrared-stimulated group than control group. Therefore, these results suggest that the thermostimulation improved immune activity.

분리층 두께가 5 μm이며 Si/Al 몰비가 1.5인 Na형 faujasite 제올라이트 분리막을 이차성장 공정에 의하여 제조하였고, 투과부에 13X 제올라이트 흡착제 충진 전후의 진공모드에서의 CO2/N2 분리거동을 CO2/N2 몰비가 1인 혼합기체에 대하여 30℃에서 평가하였다. 충진된 13X 제올라이트 흡착제는 CO2 투과도와 CO2/N2 선택도를 동시에 증진시켰다. 이 현상은 13X 제올라이트 흡착제 충진이 다공성 α-알루미나 지지체의 기공채널을 통한 CO2 탈출을 증진시킴으로써 faujasite 제올라이트/α-알루미나 상계면에서의 CO2 탈착을 증진시켰기 때문으로 설명되었다. 본 논문으로부터 흡착제와 분리막의 혼성화는 일반적으로 보여지는 선택도와 투과도의 역비례 관계를 획기적으로 개선할 방법임이 확인되었다.

This study is conducted to investigate the effects of growth characteristics (GC) and DPPH radical scavenging activity (DRSA) of the heading lettuce ‘Fidel’ depending on four concentrations of activated mineral groups (AMG: 1.6% active minerals and 0.03% CaO) added to basic nutrient solutions (diluted by 0, 0.05, 0.1, and 0.2%) and on four different light-emitting diodes (LED; B:R:W ratio = 0:1:12, 0:1:9, 0:5:5, and 2:3:5). Both 0.1 and 0.2% AMG showed better GC of lettuce in plant width, plant length, leaf width, leaf length, and the number of leaves than those of other AMG, while leaf thickness and chlorophyll value did not show significant difference among all AMG. Moreover, 0.1 and 0.2% AMG showed heavier shoot fresh weights than those of other AMG. As for the combinations of AMG and LED, B0:R5:W5 showed the best lettuce GC regardless of AMG compared to other AMG and LED combinations. As shown in the above results of LED, although there was a difference in lettuce growth by LED, the differences of lettuce growth by AMG were statistically significant. The DRSA was the highest at 82.8% in B2:R3:W5, followed by B0:R5:W5 at 77.8%. LED showed differences but AMG did not affect DRSA. Therefore, the optimal conditions in plant factory for GC and DRSA of the lettuce were 0.1% AMG and B0:R5:W5.
