PURPOSE: This study was conducted to understand the adaptive responses of different modes of physical exercises utilizing skeletal muscle and the comprehensive relevance of AMPK signaling that can be activated by physical exercise as a potential molecular target in human health problems such as neuromuscular disorders (NMDs). METHODS: Most of the contents in this review article are based on recent publications concerning the main topics of interest. The reference literatures cited were obtained by basic searches of overseas academic databases such as PubMed and ScienceDirect using EndNote X7.8. RESULTS: The phenotypic adaptive responses of skeletal muscle during endurance- and resistance-based exercise training (ET and RT respectively) appear to be distinct. To explain the adaptive responses in each single mode of exercises (ET, RT) along with combined exercise training (CT), AMPK signaling is proposed as an important molecular link among those differential modes of exercise and a promising molecular target of NMDs. CONCLUSION: Based on the available evidence, intracellular AMPK signaling activated by diverse stimuli including physical exercise can be a potential and promising therapeutic target for the prevention, amelioration or cure of various human health problems including NMDs and may also be beneficial for physical rehabilitation and emergency situations that may elicit acute metabolic stresses.

Purpose : Until recently, the number of cancer patients continues to increase, and these patients have many limitations in their activities of daily living. In the republic of Korea, cancer patients are showing an increasing trend every year. Cancer disease not only significantly reduces the quality of life in individuals, but also causes various side effects if not managed. The purpose of this study was to investigate the effects of aerobic exercise and resistance exercise on health-related problems in cancer patients. Methods : This study searched for studies that applied aerobic exercise and resistance exercise to cancer patients reported in search engines (google scala, dbpia, and pubmed) from 2017 to 2022. Six randomized controlled trials and two systematic reviews and meta-analyses were used for analysis in our study. "physical activity", "exercise", "aerobic exercise", "resistance exercise", and "cancer patient" were the main search terms. The data included aerobic exercise, resistance exercise, cancer patients' muscle strength, physical strength, quality of life, and physical activity. Results : According to the eight studies that met the criteria included in this review study, it was found that aerobic exercise and resistance exercise had an effect on the increase in physical fitness, muscular strength, quality of life, and range of motion in cancer survivors. Conclusion : It was confirmed that aerobic exercise and resistance exercise are safe and effective interventions that can be applied to cancer patients without side effects. A limitation of this study is that it did not examine cancer diseases in various population groups such as the elderly and children. Therefore, in future studies, studies that consider specific details such as age, gender, type of cancer, and physical differences are needed.

Previous studies have reported that deep neck flexor (DNF) exercise can improve neck problems, including neck pain, forward head posture, and headache, by targeting the deep and superficial muscles of the neck. Despite the prevailing opinion across studies, the benefits of DNF can vary according to the type of neck problems and the outcome measures adopted, ranging from positive outcomes to non-significant benefits. A meta-analysis was conducted in this study to assess conclusive evidence of the impact of DNF exercise on individuals with neck problems. We used PUBMED, MEDLINE, NDSL, EMBASE, and Web of Science to search for primary studies and the key terms used in these searches were "forward head posture (FHP)," "biofeedback," "pressure biofeedback unit," "stabilizer," "headache," and "neck pain." Twenty-four eligible studies were included in this meta-analysis and were coded according to the type of neck problems and outcome measures described, such as pain, endurance, involvement of neck muscle, craniovertebral angle (CVA), neck disability index (NDI), cervical range of motion (CROM), radiographs of the neck, posture, strength, endurance, and headache disability index. The overall effect size of the DNF exercise was 0.489. The effect sizes of the neck problems were 0.556 (neck pain), -1.278 (FHP), 0.176 (headache), and 1.850 (mix). The effect sizes of outcome measures were 1.045 (pain), 0.966 (endurance), 0.894 (deep neck flexor), 0.608 (superficial neck flexor), 0.487 (CVA), 0.409 (NDI), and 0.252 (CROM). According to the results of this study, DNF exercise can effectively reduce neck pain. Thus, DNF exercise is highly recommend as an effective exercise method for individuals suffering from neck pain.

Considering that the aged population increases and the mobility problem is pointed out as a factor that indisposes the quality of life, cognition, and mood, it is important to understand and evaluate the elderly's mobility. Factors that deteriorate mobility in the elderly include physical senility, various health changes including chronic diseases, polypharmacy as well as anticholinergics. Common mobility problems in old age are reduced gait speed, increased gait variability in walking length, careless walking, and frequent falls. Several studies have reported that decreased mobility and deterioration of gait can predict cognitive decline and emotional problems. Aerobic exercise, resistance exercise, and balance exercise are suggested as therapeutic interventions for mobility problems. Active correction for factors that reduce mobility in the elderly and prescribing physical activity can conserve the elderly's quality of life and help improve cognition and mood. There is a need for related research in the future.

Background: High string instrument (violin, viola) players are at high risk for developing musculoskeletal problems. In particular, a higher prevalence of shoulder problems has been reported. However, evidence of the effectiveness of therapeutic exercise for musicians with this condition is lacking until now. Objects: This case series study investigated the effect of a specific exercise program on shoulder pain, dysfunction, and posture of professional orchestral high string musicians. Methods: Five professional orchestral high string players with shoulder pain participated in this study. A six-week specific exercise program focus on scapular stability for shoulder pain consisted of scapular muscle exercise. Physical examinations for pain and dysfunction, posture were performed, were identified among all subjects before starting the exercise program. Results: The results revealed that shoulder pain decreased by 67.86% and the effect of pain on instrument play decreased by 63.33%. The shoulder pain and disability Index and the performing arts module-quick disability of the arm, shoulder and hand scale decreased by 71.72% and 51.61% respectively. The exercise program improved function and posture. Conclusion: A specific exercise program for high string players was effective in managing shoulder pain. This case series is intended to provide empirical data on the effectiveness of an exercise program aimed at assessing the effect of exercise on pain, dysfunction, and posture of professional orchestra musicians associated with specific instrument groups.

Purpose: The objective of this study was to analyze the factors affecting the stages of exercise behaviors changes of low back pain patients. Methods: The participants in this study were 220 low back pain patients who have been treated by therapeutic exercise or had the exercise treatment under the doctor's advice. The tools used for this study were the stages of exercise behavior change, intrinsic motivation questionnaires, and physical activity social support scale (PASS). Results: The group that did exercise (preparation stage, maintenance stage, action stage) was 75.9% but the group that did not exercise (precontemplation stage, contemplation stage) was 24.1%. Social supports from family members and friends and motivation affected the exercise behaviors changes. And 34.6% of the exercise behavior change can be explained by the social support (family, friend) and motivation. Conclusion: There were two recommendations for maintaining the exercise behaviors of low back pain patients based on theoretical background. First, we recommended more exercise programs which reinforce social supports from family and friend for constant exercise behaviors of low back pain patients. Second, more exercise programs for the low back pain patients who have similar health goals or problems were needed for motivating them to join the exercise programs.

미국이 대 이라크전 연장선에서 북한 핵문제를 봄에 따라, 한반도의 긴장은 날로 증가하고 있으나, 국내 여건의 변화에 따른 국방 가용재원의 감소, 대규모 야외군사훈련을 수행하기 위한 공간확보의 어려움 및 안전과 환경문제 등으로 인해 한국군의 야외훈련 여건은 날로 열악해져 가고있는 실정이다. 이에 따라, 야외훈련의 대체방안으로서 보다 경제적이고 과학적인 워게임 모델에 의한 CPX(Command Post Exercise: 지휘소연습) 즉, 워게임 연습이 최적의 대안으로 주목받고 있으며, 이를 통한 단독, 합동 및 연합연습이 수행되고 있다. 그러나, 현 워게임 연습체계는 정보보호라는 관점에서 볼 때 많은 문제점을 안고 있다. 국방전용망의 경우 그 구성이 인터넷과의 단절을 전제로 네트워크 레벨에서의 암호화만을 통해 데이터를 보호하고 있는 실정이고, 워게임 연습체계 내에서의 공격이나 신뢰하고 있는 네트워크를 통한 공격에 대해선 무방비 상태에 놓여져 있으며, 시스템 레벨에서의 보안 또한 부실한 실정에 있다. 따라서, 본 연구에서는 워게임 연습체계의 효율적이며 안전한 정보보호 방안 제시를 위해 네트워크 레벨에서의 정보보호 체계 및 시스템 관점에 초점을 두고 연구가 수행되었으며, 결론적으로 현 워게임 연습체계에서의 최적의 정보보호 방안을 제시하고자 한다.
