This paper presents 3D position estimation algorithm with the images of 2D vision sensors which issues Red Laser Slit light and recieves the line images. Since the sensor usually measures 2D position of corner(or edge) of a body and the measured point is not fixed in the body, the additional information of the corner(or edge) is used. That is, corner(or edge) line is straight and fixed in the body. For the body which moves in a plane, the Transformation matrix between the body coordinate and the reference coordinate is analytically found. For the 3D motion body, linearization technique and least mean squares method are used.

The reliability of wireless body area networks is an important research issue since it may jeopardize the vital human life, unless managed properly. In this article, a new modeling and analysis of node misbehaviors in wireless body area networks is presented, in the presence of multi-type failures. First, the nodes are classified into types in accordance with routing capability. Then, the node behavior in the presence of failures such as energy exhaustion and/or malicious attacks has been modeled using a novel Semi-Markov process. The proposed model is very useful in analyzing reliability of WBANs in the presence of multi-type failures.

Recently, Wireless Body Area Network (WBAN) has promise to revolutionize human daily life. The need for multiple sensors and constant monitoring lead these systems to be energy hungry and expensive with short operating lifetimes. In this paper, we offer a review of existing work of WBAN and focus on energy-aware management in it. We emphasize that nodes computation, wireless communication, topology deployment and energy scavenging are main domains for making a long-lived WBAN. We study the popular power management technique Dynamic Voltage and Frequency Scaling (DVFS) and identify the impact of slack time in Dynamic Power Management (DPM), and finally propose an enhanced dynamic power management method to schedule scaled jobs at slack time with the goal of saving energy and keeping system reliability. Theoretical and experimental evaluations exhibit the effectiveness and efficiency of the proposed method.

Garment is made by a 2D pattern and should be fitted to a human body which has 3D characteristics. Therefore, to design a pattern more effectively, the use of 3D information of a human body and the investigation of relationship between the 3D garment and 2D pattern are necessary. In this work, ruled surface method was used to reflect the 3D information of a human body for a pattern design. The images of the brassiere line on the woman's dress form were captured by phase-shifting projection moire system and the 3D information on the design line was obtained. 2D patterns on the various parts of the brassiere were developed directly from the 3D data by the ruled surface method. In addition, design line, the area and the amount of dart were quantified. And then we verify the appropriateness of the ruled surface method to the 2D pattern development by measuring the distribution of the space between women's figure and segmented clothing item. It was found that the ruled surface method is useful to transform the 3D design line to the 2D pattern, if we followed the steps suggested in this paper.

The society advance of a development of the science technique and women from the industrialization, women prefered the tailor-made clothes to the convenient ready-made clothes in the aspect to be economic and save time in the clothing habits. After marriage, middle age women change the comparison of their body due to the pregnancy and birth, the body girth of them increases compared with young woman, the winding of the waist comes to be small and they show the feature of body which the vibration thickness and the brachial girth grows bigger. The reason is that the problem on the fitness of the ready-made clothes comes into being. According to this result which analyzes a ready-made clothes body of the jacket-brand which does the middle age woman to the target in research, actual purchasing age appears than the age which most companies do to the target so that it is high, and though the body is divided in KS standard, the measurement distinguished without the body and most companies were producing the jacket. There was many case to select a fitting model Among a designer or within firm employee with the similar body and measurement. It was revealed that high rate of mending relation of a sale jacket of the company. Research about the body of the ready-made clothes is thought by continuing over there.

This study was conducted to investigate whether whole body cryotherapy and spinal decompression have effectiveness on the pain, lumbar flexion range of motion, and global perceived effect scale in patients with lumbar disc herniation. Thirty subjects were participated in this study. And they were all randomly divided into whole body cryotherapy and spinal decompression group. To evaluate the effects of whole body cryotherapy and spinal decompression, subjects were evaluated by using visual analogue scale, lumbar flexion range of motion, and global perceived effect scale. The assessment parameters were evaluated before, after 2 weeks treatments. And we received a consent form whole body cryotherapy subjects. The results of paired t-test, independent t-test, and ANCOVA analysis of variance showed that pain, lumbar flexion range of motion, global perceived effect scale were significantly improved after than before therapy in whole body cryotherapy group. So we conclude that whole body cryotherapy has effectiveness on the pain, lumbar flexion range of motion, and global perceived effect scale in patients with lumbar disc herniation.

This study was undertaken to compare the obesity related dietary factors among rural middle school students living in Korea. Anthropometric data showed that mean height and weigh were 161.7$\pm$13.0 and 49.8$\pm$10.3kg in 226 male students and 158.3$\pm$6.1 and 48.2$\pm$7.5kg in 212 female students. Mean BMIs for boys and girls were 19.10$\pm$2.47 and 19.26$\pm$2.35, respectively. 71.68% of male students and 72% of female students were underweight by the BMI index. The BMI of older students was higher than young ones in both sexes. Most nutrient intakes of the subjects were below the RDA. In particular Ca and Fe intakes were extremely low in both sexes. 66.88% of the students skipped breakfast and it was found that the reasons for missing a meal for both sexes were significantly different. Compared to males, more female respondents felt guilty and depressed related to eating. Furthermore, females were more significantly concerned with body image, diet, and body weight(p〈0.001), and they were not satisfied with their weight. The sources of information on obesity and diet were from radio and TV in males while females got information from magazines and friends. In male students their ideal body weight was higher was higher than actual body weight. In contrasting, female students desired a thin body shape. A different approach for nutrition education for adolescents should be developed and implemented based on sex.

In this study, 3D measurement data of 70 to 85 years old men were analyzed to investigate the body shape characteristics. and the type of the whole body of older men. Through this study, we aimed to provide basic data necessary for making good clothes for elderly men. We analyzed the body shape of elderly males using Korea 's 2015 elderly anthropometric data by SPSS Ver. 24.0. The body shape of older males was classified into four types: 'thin & long inverted triangle with thick legs', 'thick & short inverted triangle with bird legs', 'thick & long triangle with thick legs', 'thick & short triangle with thick legs'. As the age increases, the shoulders are sagging, the progressive reduction of the spine leads to a decrease in height, and the backbone refraction causes a decrease in the anterior center length and an increase in the back length. In addition, as the age increases, the chest circumference decreases and the abdomen and waist circumference increase. Considering these physical changes, it is necessary to set the length of the garment to 2-3cm shorter in the case of the aged layer. Waist and abdomen area are increased, it is considered that it will be necessary to add more margin of 2cm than general silver clothing when setting the margin amount. When setting the length of the upper body, it is considered that the front center length should be reduced and the back length should be increased to keep the bottom level. In this study, only the elderly males aged 70-85 years were included in the analysis of the whole body type. It is significant that the studies so far have been extended to those older than 70 years. Future research will need to be applied to the development of silver clothing through comparison of older men 's body shape in their 60s and 70s.
