  • 최근 좌식생활과 컴퓨터사용의 증가로 전방머리자세 가진 젊은 성인이 증가하고 있으며 이를 개선하기 위한 슬링 뉴렉기법을 적용한 복합운동의 효과를 알아보고자 실시되었다. 이 연구의 결과 운동군에서 통증, 목뼈 앞굽은각, 중력중심선에서 유의한 감소가 나타났다(p<.001). 이러한 결과는 슬링뉴렉을 적용한 복합운동이 억제된 근육에 신경근 활성화와 근육의 재교육을 통해 통증 및 목뼈정렬에 긍정적인 역할을 한 것으로 생각되며 전방두부자세 개선을 위한 효율적인 중재 방법이 될 수 있는 가능성을 확인하였다.

  • The aims of this study are to investigate the walking intention detection of a rollator based on Infraed (IR) sensor measuring knee joint anterior displacement and leg muscle activities. We used Active Walker attached IR sensor to measure the knee joint anterior displacement and EMG signal of leg muscles(rectus femoris, biceps femoris, tibialis anterior, gastrocnemius) were taken by Delsys bagnli-8ch. Subjects were eight healthy males(age $23.7{\pm}0.5years$, height $175.4{\pm}2.3cm$, weight $70.6{\pm}5.6kg$) and they were involved in experiments which had been proceeded 30 minutes a week, during 3 weeks. This system indicates that the knee joint anterior displacement had the distinction increases according to the gait slope and velocity. We showed the increase of the femoral muscle activities along the anterior tilt and the increase of the crural muscle activities along the posterior tilt.

  • As the elderly population increases, it is becoming important to prevent and treat muscle loss caused by aging or disease. Steroidal androgen in the protein assimilation steroid (AAS) system is mainly used to induce muscle improvement, but it is well known that long-term or excessive doses of AAS result in various side effects, although they are prescribed for various muscle and weight loss treatments. Research is therefore underway to explore natural substances that promote muscle renewal with relatively few side effects. However, despite many studies on the improvement of skeletal muscle and the reduction of muscle disease using natural products, there is still a lack of significant clinical results and mechanism studies. The promotion of muscle regeneration through treatment with natural substances typically involves three mechanisms: positive control of the muscle modulating factor (MRF), activation of the protein synthesis mechanism, and inhibition of the protein breakdown mechanism. A study of plant extracts that are known to have muscle neoplasmic stimulation effects, such as black ginseng, plum, and nutmeg, as well as single substances derived from natural products, such as creatine, catechin, and several fatty acids, is therefore described. We also summarize the mechanisms that have been identified so far through which each of these extracts or single materials facilitates muscle regeneration and the signaling pathways that they mediate.

  • The electromyographic activity of four muscles(biceps, supraspinatus, infraspinatus and subscapularis) was mea­sured from non-dominant shoulders of 12 volunteers by six different provocative test for the biceps pathology. The provocative tests were Speed, Yergason, Ludington, Heuter, O'Brien and the abduction-extension test. Each test was performed in a force of 30% of maximal voluntary contraction. The levels of activity of the biceps were higher than those of the other rotator cuff muscles only in Speed's test: 28% in the biceps, 26% in the infraspinatus, 25% in the supraspinatus and 21 % in the subscapularis. The levels of activity of the biceps as a percent of MMT(maximal manual test) were higher in Speed's(42%) and O'Brien's test with the arm supinatecl(42%). Speed's test can isolate the activity of biceps better than the other tests but it is a nonspecific test by which the biceps tendon was also activated within other rotator cuff muscles.

  • Total lipids from the roe, muscle and viscus of L. carinata were analyzed for lipid composition by column chromatography, thin-layer chromatography and gas-liquid chromatography. The roe lipids were characterized by a high level of wax esters (63.1%) and a low proportion of trigiycerides (9.9%). The viscus lipids also contained wax esters (32.8%) as its main component, followed by free fatty alcohols and acids (23.5%). On the other hand, the muscle lipids were found to contain a large amount of triglycerides (66.1%) with a trace of wax esters. The main fatty alcohol component of roe and viscus wax esters was C16:0 alcohol (53.0%; 61.7%), accompanied by C18:1 alcohol (10.2%) in the former and by C15:0 alcohol (8.8%) in the latter. Considerable amounts of odd-numbered fatty alcohols were found in both wax esters. On the other hand, the fatty acids of the roe and viscus wax esters contained a high percentage of monounsaturated (49.7%-56.6%) consisting of C16:1, C18:1 and C17:1 acid, and a significant amount of polyunsaturated (41.2%-32.9%), particularly C20:5${\omega}$3. The fatty acid components of triglycerides and phospholipids were different among the tissues tested, especially between roe and muscle or viscus. The fatty acid compositions of free fatty acids from the muscle and viscus were characterized by a higher level of polyunsaturated fatty acids (46.0-34.3%) compared to those of triglycerides 'in the roe, muscle and viscus (28.4%, 19.4% and 19.2%).

  • 고양이를 제외한 포유동물 및 조류는 oocyst 또는 cyst의 섭취로 감염되고 무성생식을 한다. 급성기에는 tachyzoite ($2~3{\times}5~7$\;\mu\textrm{m}$)가 여러 장기에서, 숙주 변역이 활성화된 이후인 만성기에는 100~1,000 개의 bradyzoite를 내장하며 주변에 염증반응이 없는 cyst (직경 $20~50;\mu\textrm{m}$)가 근육 및 뇌에서 관찰된다. Tachyzoite는 태반을 통해 태아 감염을 일으킨다. 고양이는 oocyst 또는 cyst의 섭취로 감염되고, 기타 동물에서 보이는 감염양식 외에 소장에서 coccidiosis양의 증식이 이루어짐으로 oocyst (Isospora 형, $10{\times}12;\mu\textrm{m}$)를 배출한다.

  • 칼슘은 인체의 필수 원소로서 뼈나 치아의 조직에 강도를 부여하는 신체 지지기능 이외에 체액의 pH를 약 알칼리성으로 유지시켜 장관으로부터 흡수한 영양소를 각 세포에 부드럽게 전달하여 세포 및 효소의 활성화에 의한 근육의 수축, 혈액 응고 및 여러 가지 심혈관계 질환의 예방에 관여하는 기능을 한다. 따라서, 칼슘의 흡수가 부족한 경우에는 뼈나 치아의 발육이 나쁘게 되어 성장이 늦고, 피로를 쉽게 느끼며, 고혈압, 심장병 및 뇌졸증 등의 성인병 및 골다공증의 원인이 된다. (중략)

  • 근년 경제성장과 더불어 늘어나는 맞벌이 부부, 교통 체증 등과 같은 사회적, 경제적 요인으로 즉석 식품의 수요가 급증하고 있고, 이로 인하여 칼슘 등과 같은 유용무기성분 및 비타민 등과 같은 미량 성분이 결핍되기 쉽다. 칼슘은 뼈나 치아의 조직에 강도를 부여하는 신체 지지기능 이외에 체액의 pH를 약 알칼리성으로 유지시켜 장관으로부터 흡수한 영양소를 각 세포에 부드럽게 전달하여 세포 및 효소의 활성화에 의한 근육의 수축, 혈액 응고 및 여러 가지 심혈관계 질환의 예방에 관여하는 기능을 한다. (중략)
