This study evaluated the effects of physical touch play programs in children through a systematic literature review and meta-analysis. A literature search for journal articles published before August 2022 was conducted using KERIS, KISS, DBpia, and ScienceON. The keywords used for the search were 'child', 'infant', 'physical touch', 'physical touch play', 'physical touch activities' and 'physical touch play program'. For the study's purpose, seven studies were selected through a systematic process of using several databases and were used to estimate the effect size of physical touch play programs. A meta-analysis was performed using a random effects model, and the effect size on cognitive function was calculated. Hedges' g of the physical touch play program was 6.20 (95% CI: 3.74-8.66), indicating a large effect size. To determine heterogeneity (I2= 95.4%, Q = 417.30, p<0.001), moderator analysis was performed using the total number of times and intervention duration. The total number of times was statistically significant; the other moderators did not differ significantly. This study systematically analyzed the results of physical touch play programs on children in Korea. It also provides insights that can be applied to the design of physical touch play programs for children. To present more evidence that supports the effectiveness of physical touch programs, further research is warranted.

The purpose of this study was to examine the indirect estimation of the lumbar intervertebral disc size by two anthropometric methods(Colombini's method and Turk and Celan's method), in order to compare these indirect methods with the direct analysis by computed tomography(CT). The wrist, elbow, knee and ankle joint(right side) diameters were measured in 52 normal volunteers and intervertebral disc sizes were measured in 50 normal subjects by CT. Then the intervertebral disc sizes were calculated using two anthropometric formula. The data were analysed with ANOVA to differentiation between indirect and direct estimation of the lumbar intervertebral disc sizes. This study shows that male subjects have significantly larger L4-5 and L5-S1 intervertebral disc sizes than female subjects. In addition, disc sizes calculated by Colombini's formula were significantly larger than Turk & Celan's formula but there was no significant differences in the compared Turk & Celan's estimation with CT values. The indirect estimation of the intervertebral disc size by Turk & Celan's formula can be considered as a clinically useful method. However, further study should be conducted to compare anthropometric values according to age.

In this paper, we propose an effective method for recognizing daily human activities from a stream of three dimensional body poses, which can be obtained by using Kinect-like RGB-D sensors. The body pose data provided by Kinect SDK or OpenNI may suffer from both the view variance problem and the scale variance problem, since they are represented in the 3D Cartesian coordinate system, the origin of which is located on the center of Kinect. In order to resolve the problem and get the view-invariant and scale-invariant features, we transform the pose data into the spherical coordinate system of which the origin is placed on the center of the subject's hip, and then perform on them the scale normalization using the length of the subject's arm. In order to represent effectively complex internal structures of high-level daily activities, we utilize Hidden state Conditional Random Field (HCRF), which is one of probabilistic graphical models. Through various experiments using two different datasets, KAD-70 and CAD-60, we showed the high performance of our method and the implementation system.

의복은 사람의 신체적인 특징에잘 맞고 심리적으로 만족을 주는 것이어야 한다. 식죽(1989)은 인간관계와 사회구조가 복잡하게 서로 얽혀 이루어진 현대사회에서는 의복에대한 욕구는 다면적이고 모든 기능을 동시에갖는 것이 요구되어진다고 하였고 정삼호(1988)는 성인여성들은 연려이 증가함에 따라 나타나는 체형변화를 의복으로 최대한 보완할 수 있는 디자인을 선택하여 다른 사람들에게 의복을 통해 자기 자신을 표현함으로서 심리적으로 안정감을 얻으려고 노력한다고 하였다. 따라서, 의복 착용 자가 의복을 통해얻는 심리적 만족도는 신체적 만족도와 관련되어 형성된다고 할 수 있으며 또한 신체 적 만족도는 체형과 관련되어 형성된다고 할 수 있다 (정재은,1992). 이에 신체적 만족도와 의복행동 및 체형에 관한 연구가 많이 이루어지고 있다. 이옥연(1984), 식죽(1988), Labat-Delong(1990), 김용숙 (1990), Shim(1991), 구자명.이명희(1994), 고애란.김양진(1996) 등은 신체 만족도와 의복행동간에 관련 이 있음을 밝혔으며, 임숙자(1986), 김양진.강혜원(1992)은 신체의 결함을 의복으로 보완하고자 하는 경향이 있다고 하였고, 김정숙(1984)은 자신에게 어울리는 의복을 선택하므로써 안정감을 갖게된다고 하였다. 또한, Douty. Brannon(1984)은 여성은 마른것을 선호한다고 하였고 Clayton 등(1987)은 의복 착용자의 체형에 따라 의복 유행성 지각이 다름을 밝혔다. 그러나, 이에관한 대부분의 연구들은 심리 학적 입장에서 행하여진 연구로 신체의 종합적인 만족도, 선호를 취급하고 있을 뿐 신체각 부위의 만족 도나 선호에 관한 자세한 고찰을 하고 있지 않으며 자신의 신체에 대한 인식도 및 실제체형과의 비교는 이루어지고 있지 않다. 이에, 신체 각 부위에 대한 인식도 및 실제 신체 측정치와 만족도와의 관계 및 이상형에 대해 구체적으로 파악할 필요가 있다. 또한, 신체에 대한 이상형은 시대의 여러 여건에 따라서 변화할 수 있으므로 의복 착용자가 의복을 통해서 표현하고자 하는 이상형의 시대적 변화를 살펴볼 필요가 있다. 따라서 본 연구에서는 신체에 대한 인식도 및 만족도, 이상형에 대한 설문지 조사와 신체측정을 통하여 신체 크기에대한 만족도를 객관적인 척도로 고찰하고, 이상형과 실제 체형에 관하여 고찰하고자 한다. 도한, 1992년도 자료와의 비교를 통하여 시대에 따른 신체만족도와 이상형의 변화를 파악하고자 한다. 이를 기초로 한 의복원형 제작 및 의복 디자인에 대한 연구를 통해 의복의 맞음새가 좋을뿐만 아니라 의복착용자들 에게 심리적 만족을 줄 수 있는 의복 제작에 도움이 될 수 있을 것이다.

This study was a systematic review and meta-analysis designed to investigate the effects of physical activity programs on sleep among community-dwelling elders in Korea. Based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, research articles published until November 20, 2016 were systematically analyzed and a total of seven papers were finally selected. Meta-analysis of the studies was conducted using Comprehensive Meta-Analysis 3.0. The results showed that the total effect of the physical activity program for elderly people, such as healing yoga, aerobic dance, aquarobics, Korean dance, BeHas exercise, exercise programs and Tai Chi exercise on sleep was Hedges' g=0.577 (95% CI: 0.337-0.817) The BeHas exercise program had the largest effect size on elderly's sleep, with a Hedges' g=0.758 (95% CI: 0.248-1.267). This was followed by the Tai Chi exercise program (Hedges' g=0.697; 95% CI: 0.071-1.324) and the exercise program (Hedges' g=0.650; 95% CI: 0.141-1.159). Therefore, when applying nursing interventions to improve quality of sleep of elderly people living in the community, it would be helpful to apply the BeHas exercise and the Tai Chi exercise, which have a positive effect on sleep of the elderly.

This paper proposes a real-time algorithm for tracking the fast moving human body. Although Iterative closest point (ICP) algorithm is suitable for real-time tracking due to its efficiency and low computational complexity, ICP often fails to converge when the human body moves fast because the closest point may be mistakenly selected and trapped in a local minimum. To overcome such limitation, we combine a particle filter based on a motion history information with the ICP. The proposed human body motion tracking algorithm reduces the search space for each limb by employing a hierarchical tree structure, and enables tracking of the fast moving human bodies by using the motion prediction based on the motion history. Experimental results show that the proposed human body motion tracking provides accurate tracking performance and fast convergence rate.

Purpose: The goal of this study was to examine body image satisfaction and perception according to weight status, and to investigate those associations with dietary habits and nutritional status among preadolescent children. Methods: Body image and dietary habits and intake were assessed in 134 elementary school students in grade 4. Children were categorized according to normal and overweight or obese groups. Figure rating scales were used to assess body image perception (identification of perceived current body size) and dissatisfaction (difference between perceived current body size and ideal body image). Results: There were sex differences in body image perceptions. Normal-weight girls, overweight or obese girls and boys were more likely to desire a leaner body size than their perceived body size compared with normal-weight boys. Body image satisfaction and perception showed an association with weight status. More overweight or obese children indicated dissatisfaction or underestimation of body image than normal-weight children. Children with body image dissatisfaction due to heavier perceived body size than ideal body image showed lower frequencies of consumption of meals and vegetables, compared to those who were satisfied with their body image. Children who underestimated their body image were more likely to have a lower frequency of breakfast and meal regularity and a higher frequency of eating out of home or food deliveries than those with accurate body image perception. In addition, body image underestimation showed an association with lower intakes of protein, dietary fiber and calcium, and the higher percentage of calories derived from fat. Conclusion: Body image dissatisfaction as well as underestimation in children before puberty showed an association with overweight or obesity, and was also related to unhealthy dietary habits. These findings highlight the importance of accurate perception and satisfaction with body image in preadolescent children in order to prevent development of obesity in adolescents and adults.
