Generally, Tension-Type Headache(TTH) patients exhibit muscle pain, but can also have TMJ pain, which includes mouth opening limitation or joint sounds. The purpose of our study is to observe the clinical pain characteristics between TTH patients with muscle pain and TMJ pain. One hundred sixty-seven patients were diagnosed with TTH according to the questionnaires based on the International Headache Society's proposal on the diagnostic criteria of TTH. The patients were classified into three group; arthralgia group (18 patients), myalgia group (50 patients) and arthromyalgia group (99 patients). TTH patients with pericranial muscle pain were classified in the myalgia group. TTH patients with temporal region pain were classified in the arthralgia group. TTH patients with both types of pain were classified in the arthromyalgia group. The parameters in the diagnostic criteria such as quality, intensity, laterality of pain, and aggravation due to physical activities were compared among the three groups. 1. There were no significant differences in the quality of pain among the three groups. 2. There were no significant differences in the intensity of pain among the three groups. 3. There were no significant differences in the laterality of pain among the three groups. 4. A higher percentage of patients in the arthromyalgia group experienced headaches that were aggravated due to physical activity (p=0.03) compared to the other groups. The results of this study show that TTH patients with both arthralgia (TMJ pain) and myalgia (pericranial muscle pain) are more aggravated by physical activity than TTH patients with either one.

운동을 하게 되면 높아진 혈당이 떨어지게 된다. 이는 운동이 열량을 소모시키고 근육으로 혈액 순환을 증가시키며 혈당을 낮추는 호르몬인 인슐린의 작용을 도와주기 때문이다. 단, 당뇨병으로 인한 신장의 합병증이 있을 때에는 심한 운동이 오히려 해가 될 수 있으니 운동 강도를 조절해야 한다.

강도다리(Platichthys stellatus)는 분류학적으로 가자미목 강도다리속에 속하는 어류로서 우리나라 북부연안, 일본, 태평양 일대에 광범위하게 분포하며, 산란을 위해 강하류까지 거슬러 올라가는 연안정착성 어류이다. 최근 하천 및 연안의 오염으로 인하여 강도다리의 어획량이 감소하고 있어, 양식기술 개발을 위한 인위적인 어미의 성숙촉진 및 종묘생산에 대한 관심이 높아지고 있다. 그러나 넙치류와는 달리 수컷 어미의 정액량이 적어 종묘생산시 어려움을 겪고 있는 실정이다. 암컷에 비해 수컷의 정액량이 적어 종묘생산이 어려운 어종인 뱀장어(Ohta et al., 1996)와 감성돔(Lau et al., 1996)에서는 호르몬을 투여하여 정액량을 증산시켰다는 보고가 있다.

Stroke is one of the leading causes of death in Korea. Because of their sequelae, strokes are categorized as a sudden-onset, constant course chronic illness which needs continuous efforts for rehabilitation. Unfortunately, there are few community based rehabilitation program for post-stroke patients who stay at home. The authors developed a community based selp-help management program for post-stroke patients to enhance their rehabilitation process. The program consists of five sessions and each session contains health education. ROM exercise, ADL training, and stress management like foot reflexology. A professor and two graduate students of nursing college coordinated the program. To test the effects of the program we conducted a 5 week program to the 10 conveniently selected post-stroke patients who were living in Kang-buk district of Seoul. The Questionnaires about ADLs, IADLs, depression and life satisfaction were asked to the all subjects before and after program. The hand grisp power and muscle strength of four limbs were measured at the end of each sessions. The analysis of data revealed that the program was effective to increase the ADLs, IADLs, and muscle strength and to decrease the depression levels of subjects. However, there was no significant difference between pre and post hand grisp power and life satisfaction. Because the program was effective to Improve the physical and psycholocial function of subjects, we suggest continual development and Implementation of community based self-help management programs.

A computer model of the musculoskelotal system that provides accurate prediction of muscle force and body movement trom the stimulation input is desired for the effective control system design in FES. This paper aims to investigate the fundamental properties of the gradual muscle force potentiation that was not included in the previous muscle models, for future development of a model that provides vetter prediction of FES-induced muscle force and body movement. Specifically, hou the muscle length was investigated. The experimental results showed that both the force increment ratio and the time-to-peak during electrical stimulation decreased with stimulatino frequency. When the muscle potentiation state was saturated by preceding stimulation. the force did not increase any more during additive stimulation. Muscle length significantly affected the force potentiation in such a way that the force increment ratio decreased with muscle length. A new model of the muscle potentiation based on these results is desired in the future.

This study was performed to determine the effect of low-intensity resistance training with blood flow restriction (BFR) on muscle volume and strength in elderly women. Sixteen elderly women (70.9±4.6 years) were divided into low (30% 1RM) and high (75% 1RM) intense resistance training groups. Tourniquet cuff (Zimmer, Germany) for BFR was applied only to the right leg during the training period. All subjects performed unilateral leg press, leg extension and leg curl (3 sets×12 repetitions) for 10 weeks (2d/wk). Blood pressure was increased from 110 to 240 mmHg during the training period at the most proximal region of exercised leg. Muscle volume and cross-sectional area (CSA) were measured by MRI and body composition was monitored by dual-energy X-ray absorptiometry (DEXA) and isokinetic muscular strength were analyzed in both legs. The quadriceps CSA (15.2%, p<.001) and muscle volume (13.8%, p<.001) were increased in high-intense trained leg with BFR and the increased rate was highest among groups. The quadriceps CSA (9.8%, p<.001) and muscle volume (6.9%, p<.001) were increased in low-intensity training group with BFR and their increased rates were higher than control groups. The strength by exercise training was significantly improved in all groups and tended to be higher in BFR groups. These results demonstrate low-intensity resistance training with blood flow restriction could be an effective way to improve muscle volume and strength in elderly women.

The purpose of this study is to identify physical activity levels of the basic livelihood security recipients elderly women, to investigate relation between cardiovascular disease risk factors and sacrcopenia based on the levels, and to develop physical activity programs for healthy life of the elderly. The subjects of this study were 134 old females with $71{\pm}6.67$ years old who used senior centers in K-gu. The authors used the International Physical Activity Questionnaire for investigating the physical activity levels of the elderly, measuring their physical activity levels for seven days on average and classifying them into two groups, the Low Physical Activity (n=77) and the Moderate Physical Activity (n=57) groups based on the levels. Blood pressure, waist measurement, TC, HDL-C, LDL-C, TG, Glucose, and atherogenic index (AI) were measured as the cardiovascular disease risk factors; percent body fat, appendicular skeletal muscle mass, total muscle mass, and skeletal muscle index were measured as factors related to sarcopenia. Independent samples t-Test was conducted to analyze differences on the two groups based on the physical activity levels, with ${\alpha}=.05$ the as significance level. According to the results, HDL (p=.017) were higher and AI (p=.007) was lower; percent body fat (p=.008) was lower, and ASM (p=.000), total muscle mass (p=.000), and SMI (p=.001) were higher. In conclusion, moderate intensity physical activities rather than low intensity ones may have positive effects on the cardiovascular disease risk factors and sarcopenia levels, and participation in regular physical activities with at least moderate intensity by various methods may be needed for prevention of illness and healthy life of the elderly.

This study aimed to investigate the effect of hand grip force on the activity of shoulder muscles in 2 arm postures. The muscle activity of the upper trapezius, lower trapezius, infraspinatus, anterior deltoid, and posterior deltoid muscles in 22 healthy subjects (11 men and 11 women) were measured using surface electrodes during 4 hand gripping tasks (0%, 30%, 50%, and 70% of maximum voluntary contraction) in 2 shoulder positions (neutral position and $90^{\circ}$ elevation position). Among changing grip force significantly differenced infraspinatus, anterior deltoid, and posterior deltoid muscles' activity in the shoulder neutral position(p<0.05). In the shoulder $90^{\circ}$ elevation position, anterior deltoid, posterior deltoid muscles' activity was significantly differenced(p<0.05). Hand gripping was found to alter muscle activation. The hand grip task activated the infraspinatus muscle in the neutral position and inhibited the deltoid muscle in the $90^{\circ}$ elevation position. This finding may prove useful for the development preventative measures and rehabilitation strategies for shoulder injuries.
