Metabolically obese but normal weight(MONW) syndrome is characterized, with potentially increased risks for development of the insulin resistance or metabolic syndrome despite their normal body mass index(BMI) < 25 kg/m2. Such characteristics could confer upon MONW individuals a type 2 diabetes mellitus and cardiovascular diseases(CVD) risk however, research on MONW is scarce. MONW individuals have metabolic disturbances typical of obese persons and are identified by having a high amount of visceral fat, a low BMI, a high fat mass, a low lean body mass, low insulin sensitivity, and high triglyceride concentrations. The purpose of this study is to review several markers as potential modulators in individuals displaying the "MONW". Body fat appears to be functionally comparable with a dynamic endocrine organ, producing and secreting various adipocy tokines, such as leptin, adiponectin, CRP, tumor necrosis factor(TNF-), interleukin(IL)-6, all of which play an important role in the onset of cardiovascular disease, and insulin resistance. Otherwise, physical activity and a lower inflammation state might be helped to reduce the number of persons at risk of diabetes, CVD complications, or premature mortality. We should provide a method to optimal treatments resolving the emerging public health problem to prevention of MONW by providing guideline for physical activity as an optimal treatment for the MONW Korean. Furthermore we expect to develop a new strategy to manage MONW Korean in this society in terms of reducing medical costs and enhancing public health care for uprising population with MONW.

The purpose of this study is to suggest a guideline for outdoor play settings in child care centers. From March to July, 2005, data were collected from 223 directors at child care centers through a structured questionnaire, field measurement survey and non-participatory observation in seventeen child care centers in Seoul and Daejeon. The statistical methods for analysing data were frequency, percentage, mean, $X^2$ and F-test. The results showed as follows: 1)the existing outdoor playground area in child care centers should be expanded more than $4\;m^2$ per child. 2) Outdoor play facilities should be equipped with two structured play sets, a play facility for unstructured play and an adventure facility to make child's various activities possible and to promote child development. 3)flooring materials for outdoor playground should be required to use more than three kinds such as solid coverings (cf. asphalt, standard concrete), wood, lawn, soil or sands. 4)to let children enjoy various activities, outdoor playground area should be composed of various play facilities like indoor play gyms and should be independent but have good connections between play facilities depending on characteristics of play activities. 5)Play spaces of outdoor playground should be composed of physical play space, unstructured and dramatized play space, rest space, space for nature and adventure space. In addition, appropriate play equipments should be provided in respective play space.

Psychsocial factors appear to play an important role in the maintenance and development of chronic disability from low back pain. Fear of pain may be more disabling than the pain itself in patients with nonacute low back pain. The purpose of this study was to identify the contribution of gender, age, depression and pain-related fear to pain intensity and disability in nonacute low back pain patients. This was a cross-sectional survey study of eighty four patients who had low back pain for at least 4 weeks. More than moderate correlations were found between pain intensity, disability, fear-avoidance beliefs and depression. Regression analyses revealed that disability ratings and fear-avoidance beliefs for work activities significantly contributed to the prediction of pain intensity, even when controlling for age, gender and pain duration. Also, fear-avoidance beliefs for physical activity, pain intensity, age and depression, significantly contributed to the prediction of disability, even when controlling for gender and pain duration. These findings suggest that disability scores and fear-avoidance beliefs for work activities are important determinants of pain intensity. They also suggest that fear-avoidance beliefs for physical activity, pain intensity, age and depression are important determinants of disability.

본 연구는 2021년 기준 고등학교 1학년생을 대상으로 조사가 진행된 2018년 아동·청소년패널조사 중1 코호트 자료를 활용하여 대도시와 중소도시별 고등학교 1학년생의 여가활동 시간이 건강상태에 미치는 영향 요인을 살펴보는데 있다. 선행연구에서는 여가활동에 관해 삶의 만족도와 사회적 관계에 대해 연구가 이루어져 있다. 그러나 도시규모에 따른 여가활동 시간이 다르고, 전반적인 건강상태에 대한 연구도 나타나지 않았기 때문에 선행연구와의 차별점을 가진다. 건강상태의 영향 요인은 대도시와 중소도시의 평일과 주말 모두 운동 및 신체활동은 정(+), 스마트폰을 가지고 노는 시간은 부(-)의 영향력이 나타났다. 도시규모별로 구분해서 살펴볼 때는 대도시에서는 평일과 주말 모두 이외에 친구들과 노는 시간은 정(+), 중소도시에서는 평일과 주말 모두 TV를 시청하며 노는 시간이 정(+)의 영향으로 나타나 도시규모별로 차이가 있는 요인도 나타났다. 따라서 도시규모에 따라 평일과 주말의 여가시간 건강상태 영향 요인은 동일한 문항도 있었지만, 다른 문항도 나타났다. 대도시의 경우 도시의 발전으로 인해 친구들과 야외에서 여가, 문화생활을 즐길 수 있는 환경이 마련되어 요인의 차이가 발생한 것으로 생각할 수 있다. 도시규모별로 건강상태에 정(+)의 영향이 미치는 여가활동은 여가활동이 보다 활발히 이루어 질 수 있도록 관련 시설의 확대 등의 지원이 필요하고, 부(-)의 영향이 미치는 여가활동은 감소하도록 하고 다른 여가활동을 가질 수 있도록 하는 방안이 고려되어야 할 것으로 사료된다.

Back muscles play an important role in protecting the spine. Epidemiological studies have shown that loads imposed on the human spine during daily living play a significant role in the onset of low back pain. No previous study has attempted to correlate the response of the trunk musculature with the type of external load. The purpose of this study was to use surface electromyography (EMG) to quantify the relative demands placed on the back muscles while lifting loads in one hand. Forty asymptomatic, twenty year-old subjects stood while lifting loads of 10% of body weight(BW) unilaterally. All EMG data were normalized to a percentage of the EMG voltage produced during no-load standing(%EMG). Our major analysis involved a paired t-test for repeated measures. Of particular note was the fact that the ipsilateral 10% of BW condition produced statistically less % EMG change than did the contralateral 10% of the condition.

Purpose: This study aimed to investigate the correlation between trunk stabilization muscle activation and the parameters of gait analysis in healthy individuals. Methods: Thirty healthy adults (15 male, 15 female) with no history of lower back pain (LBP) or current musculoskeletal and neurological injuries were studied. Trunk stabilization muscle activation (e.g., external oblique, internal oblique, transverse abdominis, erector spinae) were assessed using surface electromyography. To analyze gait, we measured temporal parameters (e.g., gait velocity, single support phase, double support phase, swing phase, and stance phase) and a spatial parameter (e.g., H-H base of support). Results: A statistically significant correlation was found between the internal oblique, transverse abdominis, and erector spinae muscle activity and gait velocity, single support phase, double support phase, swing phase, and stance phase. No statistically significant correlation was found between the external oblique muscle activity and the gait velocity, single support phase, double support phase, swing phase, and stance phase. No statistically significant correlation was found between the external oblique, internal oblique, transverse abdominis, and erector spinae muscle activity and the spatial parameter. Conclusion: This study demonstrated that a relationship exists between trunk stabilization muscle activation and temporal parameter (i.e., gait velocity, single support phase, double support phase, swing phase, and stance phase) during gait analysis. Therefore, the trunk's stabilizer muscles play an important role in the gait of healthy individuals.

Purpose: Protein kinase C (PKC) is a member of a family of serine/threonine kinases that are activated by diacylglycerol (DG) and PKC stimulants. PKC play a key role in signal transduction, including muscle contraction, cell migration, apoptosis, cell proliferation and differentiation. However, the mechanism relating mitogen-activated protein kinases (MAPKs) and PKC, especially in the volume-dependent hypertensive state, remains unclear. Methods: In the present study, I investigated the relationship between PKC and MAPKs for isometric contraction, PKC translocation, and enzymatic activity from normotensive sham-operated rats (NSR) and aldosterone-analogue deoxycorticosterone acetate (DOCA) hypertensive rats (ADHR). Results: Systolic blood pressure was significantly increased in ADHR than in NSR. Physiological salt solution (PSS)-induced resting tension and the intracellular $Ca^{2+}$ concentration ([$Ca^{2+}{_i}$]) were different in the ADHR and NSR. The expression of PKC$\alpha$, PKC$\beta$II, PKC$\delta$, PKC$\varepsilon$ and PKC$\xi$ were different between the cytoplasmic and membranous fractions. However, expression of the PKC isoforms did not differ for the ADHR and NSR. The use of 12-deoxyphorbol 13-isobutyrate (DPB, a PKC stimulant) induced isometric contraction in $Ca^{2+}$-free medium, which was diminished in muscle strips from ADHR as compared to NSR. Increased vasoconstriction and phosphorylation induced by the use of 1 ${\mu}$M DPB were inhibited by treatment with 10 ${\mu}$M PD098059 and 10 ${\mu}$M SB203580, inhibitors of extracellular-regulated protein kinase 1/2 (ERK1/2) and p38 MAPK from ADHR, respectively. Conclusion: These results suggest that the development of aldosterone analogue-induced hypertension is associated with an altered blood pressure, resting tension, [$Ca^{2+}{_i}$], and that the $Ca^{2+}$-independent contraction evoked by PKC stimulants is due to the activation of ERK1/2 and p38 MAPK in volume-dependent hypertension. Therefore, it is suggested that PKC activity affects volume-dependent hypertension and the need to develop cardiovascular disease-specialized physical therapy.
