  • Functional Electrical Stimulation is the clinical application of a small electric current to the intact nerves of the body, in order to trigger a muscle contraction. This contraction is then incorporated into a functional activity, for example walling. A clear distinction needs to be made between therapeutic stimulation and functional stimulation. The former being of an exercise orientation, where one would relax while the stimulation works on its own. Functional electrical stimulation on the other hand, incorporates this elicited muscle movement into an everyday activity, like standing, walking, reaching out etc. But recently, New method used to FES which updated electrode insult in muscle and small nerve branch. A lot of new research build up many countries such as England, USA, Japan, Spain, Canada. So I had been write this paper for introduce new FES method, and I hope to more enhanced motivation of therapist for the functional electric stimulation.

  • The antioxidative activity and the polyphenolic composition were examined in four different cultivars of apple (Malus domestica), 'Fuji', 'Tsugaru', 'Hongro' and 'Kogetsu', and their parts (peel, core, pulp and juice). The total phenolics, flavonoids and anthocyanins differed among the tested cultivars and parts. Peel parts had the highest total phenolics and anthocyanin content. Contributions of those phenolics to total antioxidative activity were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assays, and the linoleic acid oxidation assay. Concentration of phenolics contributes significantly to the total antioxidative activity of apples. Clearly, apple peels, especially from Hongros and Kogetsus, possess high levels of phenolic compounds and antioxidants. Therefore, apple peels may potentially function as a value-added ingredient.

  • Red pepper (Capsicum annuum L.) is one of the most consumed vegetable worldwide. In this study, we tried to suggest the possibility of Cheongyang pepper as a functional cosmetic material by identifying the physiological activity, especially antioxidant and whitening effects of Cheongyang pepper through bibliometric analysis and experimental studies. A bibliometric analysis was performed through co-word analysis of 8,892 papers retrieved from SCOPUS. 4 research fields were obtained by cluster mapping from VOSviewer software, among which we noted the antioxidant activity of extracts from Capsicum annum L.. Phenol as a useful ingredient of Cheongyang pepper was analyzed using HPLC (high-performance liquid chromatography). Antioxidant and whitening effects were evaluated by measuring DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, hydrogen peroxide scavenging activity, and tyrosinase inhibitory activity. Cheongyang pepper extract showed contents of 0.106 ± 0.01 and 0.105 ± 0.02 mg/g, respectively, in the order of gallic acid and protocatechuic acid. The extract exhibited 56.95% DPPH scavenging activity and 43.97% hydrogen peroxide scavenging activity at a concentration of 1,000 ㎍/ml. In addition, 1,000 ㎍/ml of the extract inhibited tyrosinase activity by 52.44% and 42.61%, respectively in a whitening efficacy test using L-tyrosine and L-DOPA (L-3,4- dihydroxyphenylalanine) as substrates. These results suggest that Cheongyang pepper extract and its active ingredients have antioxidant and whitening effects, and the possibility of future development as a whitening functional cosmetic material.

  • This paper proposed resource allocation algorithm for the minimum power consumption of functional unit in high level synthesis process as like DSP which is circuit to give many functional unit. In this paper, the proposed method though high level simulation find switching activity in circuit each functional unit exchange for binary sequence length and value bit are logic one value. To used the switching activity find the allocation with minimal power consumption, the proposed method visits all control steps one by one and determines the allocation with minimal power consumption at each control step.

  • Many plants and animal have long been known to have medicinal effects and therefore have been used as medicines. There are many substances that show various pharmacologic efficacy such as anti-tumor efficacy, anti-inflammatory efficacy, cholesterol-lowering efficacy, anti-coagulant of blood efficacy and anti-bacterial efficacy. I summarized the recent advances in research on physiologically functional foods. The pharmacological efficacy of dietary fiber, chitin & chitosan, DHA(docosahexaenoic acid), mushroom, alginic acid and herbs have selected as topices for discussion. I was examining the anti-coagulant activity of herbs, I discovered that Eugenia caryophyllata T. (clove) had a relatively high anti-coagulant activity.

  • 본 연구의 목적은 65세 이상 노인들의 참여활동수준과 ICF에 기반한 기능장애에 대해 조사하는 것이다. 도시에 거주하고 있는 노인 100명을 대상으로 하였으며, 한국형 활동분류카드(KACS)와 세계보건기구 장애평가척도 2.0(WHODAS 2.0)를 통해 자료를 수집하였다. 수집된 자료는 기술통계 및 상관분석, 다중회귀분석을 이용하여 분석하였다. 참여활동수준에 대한 조사결과, 도구적 일상생활 영역이 75.06%로 가장 높게 나타났다. WHODAS 2.0 하위영역 중 사람들과 어울리기, 사회참여 영역에 어려움이 가장 많았고, 자기관리와 일상생활활동에서의 어려움이 가장 낮게 나타났다. 참여활동 보유율과 기능장애에 대한 상관성을 분석한 결과, 모두 유의한 음의 상관관계가 있는 것으로 나타났다. 기능장애에 영향을 미치는 요인들로는 사회활동과 도구적 일상생활의 참여활동수준, 직업상태(은퇴)가 유의미한 것으로 나타났다. 연구를 통하여 참여활동수준이 기능장애를 설명하는 중요한 요인임을 확인할 수 있었다. 추후 연구결과의 일반화를 위한 표준화 연구가 이뤄질 필요가 있다.

  • In order to identify novel proapoptotic genes, we screened approximately 1,000 hypothetical genes whose functions are completely unknown. After these genes were transiently expressed in HeLa cells, their nuclei images were captured using automated high-speed fluorescence microscope, through which the ratio of apoptotic nuclei was estimated. We selected genes that induce greater than 3-fold increase in apoptotic nuclei compared to that of the vector control. The candidate proapoptotic genes were sequenced and their effects on cell death were further confirmed by the additional assay, DNA fragmentation ELISA. Finally, we were able to identify 4 full-length hypo-thetical genes with proapoptotic activity.

  • Retroviral integrases insert viral DNA into target DNA. In this process they recognize their own DNA specifically via functional domains. In order to analyze these functional domains, we constructed six chimeric integrases by swapping domains between HIV-1 and HFV integrases, and two point mutants of HFV integrase. Chimeric integrases with the central domain of HIV-1 integrase had strand transfer and disintegration activities, in agreement with the idea that the central domain determines viral DNA specificity and has catalytic activity. On the other hand, chimeric integrases with the central domain of HFV integrase did not have any enzymatic activity apart from FFH that had weak disintegration activity, suggesting that the central domain of HFV integrase was defective catalytically or structurally. However, these inactive chimeras were efficiently complemented by the point mutants (D164A and E200A) of HFV integrase, indicating that the central domain of HFV integrase possesses potential enzymatic activity but is not able to recognize viral or target DNA without the help of its homologous N-terminal and C-terminal domains.

  • Purpose: This study aimed to investigate the effect of active vibration exercise on trunk muscle activity, balance, and activities of daily living in patients with chronic stroke. Methods: Twenty-four patients with chronic stroke were randomly assigned to an experimental (n=12) or a control (n=12) group. The experimental group performed an active vibration exercise workout for 20 minutes a day five times a week for 4 weeks using a flexi-bar. Trunk muscle activity was measured using surface electromyography. Balance was measured using the Berg balance scale. Activities of daily living were measured using the functional independence measure. Results: The intragroup comparison showed significant differences in the rectus abdominis, internal oblique, and external oblique muscle activity values, Berg balance scale score, and functional independence measurement values in the experimental group. The intergroup comparison showed that differences in the rectus abdominis and internal oblique external oblique muscle values, Berg balance scale score, and functional independence measurement value for the experimental group were significantly related to those in the control group. Conclusion: Based on these results, this study proved that the active vibration exercise effectively improved trunk muscle activity, balance, and activities of daily living in patients with chronic stroke.
