The purpose of this study was to know influenced on the change of Oswestry back pain disability index(OBPDI), isometric muscle power(IMP), muscular activation with chronic low back pain(CLBP) patients after Trunk Stabilization Exercise. Intervention was provided 6 weeks(5 days a week). Muscular activation was measured during IMP(Muscles : transversus abdominis : TA, internal obliqus : IO, external obliqus : EO, rectus abdominis : RA and erector spinae: ES). The results were as follows. 1. OBPDI about the MBE and the SE groups had effective decrease pain and disability. 2. IMP of intervention after the MBE and the SE groups had effective improve muscle power. 3. Muscle activation during IMP of intervention after was : TA, IO, RA had increase in the MBE and the SE groups. EO muscle activation during IMP of intervention after had increase only MBE groups. This shows that the MBE and the SE groups had effective increase because it has effective improve muscle power. Therefore, this study shows ￡hat trunk stabilization exercise program influenced on the change of OBPDI, IMP, muscular activation with CLBP patients.

Intellectual disability affects all spheres of the lives of people can be who suffer from it. Unfortunately, modern medicine cannot cure intellectual disability. However, the quality of life improved by means of physical exercise. In this study, we compared the health-related physical fitness, metabolic syndrome index and mental health between a game biking group(5 participants) and a brisk walking group(4 participants). This study used a between-subject design and verified by non-parametric test. The participants performed an exercise program with warm up and resistance training for 12 weeks. A game bike was used for the physically impaired, where the individual looked at a screen and pedaled. The fasters he pedaled the faster the object on the screen movies. We measured health-related physical fitness, metabolic syndrome index and mental health. We also measured their perceived exertion and interest during the exercise by a visual analog scale. The results before and after the exercise program showed that health-related physical fitness, metabolic risk factors, mental health level were improved in both groups. As we hypothesized before the study, the game biking group showed a statistically significantly different level on the Rating of Perceived Exertion than the brisk walking group and a higher level on the Rating of Exercise Interest during the exercise program. Our results lead to a conclusion that an exercise program with the use of a game bike improve motivation for exercise participation in intellectually handicapped participants.

Purpose: The purpose of this study was to identify change in the exercise behavior and to identify factors influencing long-term adherence to aquatic exercise in patients with arthritis as a follow-up study after five years. Method: Baseline data had been collected using a structured interview 6 months after participants completed the aquatic exercise educational program. This second follow-up data collection included 133 participants from the original baseline study and was done 5 years after the original baseline study. Data was analyzed using SPSS 16 Win program. Results: The stage of change for the participants was as follows: Precontemplation (44.3%), Contemplation (24.1%), Preparation (3.0%), Action (0%) and Maintenance (adherence, 28.6%). The adherers (N=38) had significantly higher scores than non-adherers (N=91) in self-efficacy, outcome expectancy, group coherence and self-evaluation, and significantly lower scores in barriers to exercise. In logistic regression analysis, self-efficacy, group cohesion, barriers to exercise and self-evaluation were associated with exercise adherence (Chi Square=17.14, p=.002). Group cohesion (OR=2.5871, 95% CI=1.094-6.113, p= .030) was the most important factor. Conclusion: Self-efficacy, group cohesion, barriers to exercise and self-evaluation need to be considered in planning exercise programs to improve exercise adherence.

낙농가가 일반소비자들을 대면해 우리우유에 대해 이야기 나누고 낙농의 가치를 직접 알릴 수 있는 기회가 많아졌다. 지역마다 벌이고 있는 우유소비촉진 행사가 그렇고 소비자들이 낙농의 현장을 직접 느낄 수 있도록 목장 내 체험프로그램이나 문화행사와 같은 다양한 형태의 사업들도 운영되고 있다. 사실 어떠한 농축산업을 보아도 낙농만큼 보고 느낄만한 것이 많은 분야도 없을 것이다. 이렇게 흥미로운 소재를 갖고 있는 만큼 일반인들에게 친근하게 전해질 수 있다면 더욱 좋겠다. 안타깝게도 우리는 매일 있는 현장이니 대수롭지 않지만, 일반 소비자들에게 보기에 불편한 모습도 있을 수 있다는 것을 인지할 필요가 있다. 커다란 생명을 다루는 일이니 매일 엄청난 양의 분뇨가 퇴적되고 그래서 좋지못한 냄새가 발생되는 것은 당연하지만 아무런 책임의식없이 이를 방치를 하여 목장의 주변에 불편함을 제공해선 안된다는 것이다. 불편함이란 매우 주관 적일 수 있지만 그들의 느낌과 감정을 의식하지 않을 수 없게 되었다. 협회가 오랜기간 추진해온 깨끗한목장가꾸기운동 자체가 많은 것을 해결할 수는 없지만, 사육환경을 개선하고 주변 이웃들과 더불어 삶을 영위하고자 하는 요령과 정신을 담고 있다. 대체로 그렇듯, 매년 우수목장으로 선정된 목장주들을 보면 상당수가 늘 밝은 인상에 외지인들을 빈객 맞듯 대접하며, 좋은 것이 있으면 주변거주인들과도 나누며 원만한 관계를 유지하는 모습을 볼 수 있었다. 해도해도 끝이없는 목장일들, 수입유제품은 넘치고 우유는 남는다는데 이 모든게 농가잘못이라는 듯 몰아가는 요즘 일상의 작업들만으로도 이미 충분히 힘들고 괴로운 시기이다. 하지만 대대손손 이어가는 우리목장, 사회에 지속적으로 기여하는 낙농산업을 위해 더 넓게 그리고 자주 주변의 이웃과 소비지들의 시선을 의식하며 깨끗한목장가꾸기운동을 통해 우리 자신을 점검해볼 수 있었으면 좋겠다. 월간 낙농육우는 잘 관리된 목장환경을 기반으로 소비자들과의 교류에도 노력하며 우리낙농의 가치를 열심히 전달하고 있는 모범적인 목장을 둘러보았다.

Recently, adolescent's lack of exercise due to increasing physical inactivity is emerging as a social problem. Accordingly, we planned a smartphone game to increase the physical activity of adolescents. The application is able to induce the interest of the youth through the interesting factor of 'game'. Also it provides the user with information about the physical activity by measuring the amount of physical activity of the user through GPS. We propose a way to continuously motivate adolescent's physical activity through this motion interaction game application.

물리계에서 일어나는 동적 현상들은 선형해석 만으로 설명하기에는 불충분한 점이 많이 있다. 이는 기계구조물과 같은 실제 계의 진동이 기하학적 비선형성, 강성 의 비선형성 또는 경계조건의 비선형성 등의 영향으로 비선형적인 거동을 하기 때문 이다. 비선형 진동을 하는 기계 계는 우리 주변에서 쉽게 찾아 볼 수 있는데, 그 예로써 진자운동을 포함하여 동흡진기, 회전체계, 공작기계의 절삭운동, 건마찰 (dry friction) 관련 기계장치, 치차 및 기차의 바퀴와 레일 간의 접촉에서 볼수 있는 구분적 선형(piecewise linear) 진동계, 충격 진동계 등을 들 수 있다. 비선형 진동 연구는 limit cycle, 준주기운동(quasiperiodic motion), 점프현상(jump phenomena) 등의 인식에서 시작되어, 과거에는 설명이 안되어 회피되 왔던 랜덤(random) 형태의 비주기운동에 대한 연구로 까지 발전하고 있다. 비선형 진동을 다루는데 있어서 정규모드(normal mode)를 이용하는 방법이 있다. 일반적으로 선형계는 선형 정규모드 (linear normal mode)가 존재하는 것과 같이 비선형계에도 이와 유사한 정규모드가 존재한다는 사실이 연구 보고된 바 있다. 비선형계에 존재하는 정규모드는 계의 매개 변수(system parameters)에 따라 그 안정성이 바뀔 수 있으며, 만일 안정한 정규모드 가 어떤 매개변수에서 그 안정성이 바뀐다면 선형이론으로는 설명될 수 없는 새로운 운동이 일어나고 이러한 운동을 분기모드(bifurcation mode)라고 한다. 안정한 정규 모드 및 분기모드를 포함하여 비선형계를 다류는 것을 "정규모드 동역학(normal mode dynamics)"이라고 한다. 정규모드 동역학은 앞에서 언급된 비선형 현상들의 원인규명, 예측, 안정성해석 및 강제진동 해석을 가능하게 한다. 또한 최근에 활발히 연구되고 있는 혼돈운동(chaotic motion)의 해석도 가능하다. 이 글에서는 비선형 진동해석을 위한 정규모드 동역학에 대한 연구동향 및 기본 이론을 살펴 보았고, 그 적용 예를 통하여 실험결과와 비교 고찰 함으로써 정규모드 동역학의 적용성을 서술하여 보았다. 선형이론으로 이해하기 어려운 현상들에 대하여는 비선형의 관점에서 새롭게 접근하 려는 노력이 필요하며 비선형 이론에 대한 연구가 지속적으로 진행되어야 한다. 진행되어야 한다.
