This paper proposed a framework for handover method in continuously tracking a person of interest across cooperative pan-tilt-zoom (PTZ) cameras. The algorithm here is based on a robust non-parametric technique for climbing density gradients to find the peak of probability distributions called the mean shift algorithm. Most tracking algorithms use only one cue (such as color). The color features are not always discriminative enough for target localization because illumination or viewpoints tend to change. Moreover the background may be of a color similar to that of the target. In our proposed system, the continuous person tracking across cooperative PTZ cameras by mean shift tracking that using color and shape histogram to be feature distributions. Color and shape distributions of interested person are used to register the target person across cameras. For the first camera, we select interested person for tracking using skin color, cloth color and boundary of body. To handover tracking process between two cameras, the second camera receives color and shape cues of a target person from the first camera and using linear color calibration to help with handover process. Our experimental results demonstrate color and shape feature in mean shift algorithm is capable for continuously and accurately track the target person across cameras.

L Company is producing the second sept pin, Shadow Mask which is the chief part of CRT in W, Monitor. Inside of the CRT pan, Shadow Mask leads the electronic beam to express the three primary colors; red, green, blue, and it is the core part to embody the colors. In the etching process, it produces this part with manufacturing by eroding the iron chloride. Even though the iron chloride is harmless to human body. it is necessary to diminish the amount of it on the view of preservation of environment. In addition, by studying the method of the dispossed liquid process, cutting down the manufacturing cost is a necessary task on the aspect of reconsideration of competitive business. This study shows the case that through the six sigma innovation activity, it reforms the following the former processing flow, and it reduces the amount of it by improving the efficiency of the iron chloride. By rationalization of the standard requirement cooperative company, it could cut down the manufacturing cost in the cooperative company, so it could promote the common profits.

In Muju County, one of Korea's major apple producers, the regional agricultural cooperatives united together and invested to establish a cooperative joint business corporation in charge of the sales business. The corporation carried out the sales business transferred from the participating regional agricultural cooperatives. While the two participating cooperatives showed a marked difference in the degree of participation at the beginning of the business, the introduction of the agricultural product processing centers (APCs) and the participation of co-selection and shipment organizations and general farms helped settle this gap. In addition, commercialization through the APCs enhanced the market competitiveness of apples, which led to the stable securing of sales outlets. The corporation integrated the sales business in the county and this resulted in increased sales volume and sales revenue. Playing a leading role in introducing and cultivating new crops on a trial basis, the corporation demonstrated its potential as the main body of the joint sales business.

The purpose of this study was to investigate the effect of the upper body in order to increase a propulsive force in the old's walking. The subjects were each 10 males, the latter term of the aged and former term of the aged. There were three walking speeds of slow(about 5km/h), medium(about 6km/h), and maximum speed(about 7km/h). The subjects walking 11m were filmed the 5m section (from 3m to 8m) by 2-video cameras using three dimensional cinematography. And we computed different mechanical quantities and especially computed the relative momentum in order to achieve this study's aim. In this study, we was able to acquire some knowledge. The step length and step frequency increased in proportion to the walking speed, and the faster walking speed, the shorter ratio of supporting time( both legs supporting time/one step length time). When it was one leg support phase, the torso was indicated to generate the momentum in order to produce the propulsive force of walking. The upper and lower body had a cooperative relation for walking such as keeping step rate with the arms to legs and maintaining the body balance. The opposition phase for upward-and-downward direction of the torso and arms in walking was functioned to prevent the increase rapidly toward vertical direction of the center of gravity. The arms had contributed to coordinate the tempo of legs and the posture maintenance of the upper body. And by absorbing the relative momentum from the upper torso with arms to the lower torso, it had the rhythmical movement on upward-and-downward direction reducing the vertical reaction force. On account of the relations of absorption and generation of the propulsive force and the production of vertical impulse in the lower torso when walking by maximum speed, it was showed that the function of lower torso was come up as important problem for the mechanical posture stability and propulsive force coordination.

The purpose of this study is to analyze work values of undergraduates according to major and gender. The result of this research is following. First, undergraduates from engineering and social science department took a very serious view of achievement and leasure of body and mind in work values. Second, undergraduates made much of achievement, job stability, leasure of body and mind, economic compensation and reputation. And undergraduates thought that internal value orientation was more important than external value orientation. Third, two groups had significant difference in service, knowledge pursuit, patriotism, economic compensation, reputation, and indoor activity. Fourth, the result of this analysis according to gender is following. Male undergraduates made much of leasure of body and mind, achievement, job stability, knowledge pursuit, and economic compensation in order. But female undergrduates made much of economic compesation, leasure of body and mind, achievement, and job stability in order. Fifth, that undergraduates make little of domain of service and patriotism gives a suggestion as to improvement of course education. As a result, this study is suggestive of instruction and advice in course search curriculum.

Although several supplementary foods are available for pregnant and lactating women, there is a need for foods able to maintain a woman's beauty without any changes in body shape. In this study, four questionnaires about nutrition management, skin care, body shape, and the intent of purchasing beauty supplementary foods, were prepared for an online survey (http://pms8011.wixsite.com/project). A total of 95 answers from 293 women were classified into four groups, based on age, income, occupation, and skin type. The data were statistically analyzed using SPSS/WIN Program 22.0. The significances of the F-value analyzed by one-way ANOVA and the differences within the groups were verified by Scheffe's method. All groups were shown to have very high requirements for nutrition management and beauty standards. In the skin patterns, the groups of middle-aged women, house wife and the lower income showed high interests, with a high significance (P<0.01) in ages. With respect to body shape, significant interest was found within the groups of skin type (P<0.05) and age (P<0.001). With regard to supplementary foods, all groups showed a strong intention to purchase, but no significant differences were found. This study indicates the necessity to categorize supplementary foods by the intended target group, such as women planning to conceive, pregnant women, and lactating women.

Purpose: This study was to identify predictors of sexual function in gynecologic cancer patients. Methods: The participants were 154 patients treated at a university medical center in A city, Korea. The data collection was performed through a structured questionnaire from July to December, 2010. The instruments used in this study were Female Sexual Function Index (FSFI) perceived health status scale, Eastern Cooperative Oncology Group (ECOG) performance status, body image, and depression. Data were analyzed using descriptive statistics, Mann-Whitney test, Kruskal-Wallis test and stepwise multiple regression with the SPSS 18.0. Results: The mean score of perceived health status was 8.42 and sexual function was 8.42. The lowest score among sexual function was lubrication. The scores of sexual function was significantly different by age, job, marital status, period after diagnosis of cancer and diagnosis. There were significant correlations between sexual function, perceived health status, ECOG performance, body image and depression. In multiple regression analysis, predictors were identified as ECOG performance, age, diagnosis and period after diagnosis of cancer (Adj.$R^2$=.28). The most powerful predictor of female sexual function was ECOG performance (19.0%). Conclusion: The above findings indicate that it is necessary to develop a more effective and personalized sexual function improvement program for gynecologic cancer patient.

This study applied DEA analysis to measure the relative efficiency of 35 companies that produce automobile body components. First, the input and output, the improvement target value of the calculated variables, and the reference group for benchmarking for inefficient groups to become efficient groups were established through DEA analysis. In addition, whether inefficiency was due to technical inefficiency or size was analyzed in connection with the cases of the actual companies through the measurement of scale efficiency. Second, a route for efficiency improvement was derived through DEA-Tier analysis by defining the possible group for benchmarking in actuality within the production industry of automobile body components where the primary cooperative company belonged. Third, the financial variables that generate the difference between efficient and inefficient groups were derived through logistic regression analysis. Financial strategies that determine the direction the indices should be improved to allow the inefficient group to become an efficient one were recommended. This research is expected to provide diagnostic methods for management efficiency and the direction of improvement to enhance the management efficiency of automotive parts makers by identifying the causes of the inefficiency of domestic automotive parts makers empirically. The study also provides financial strategies together with the target values of efficiency improvement for each individual company.

Purpose: The purpose of this study was to explore the meanings of 'Natural childbirth' from experiences of Korean women who gave birth to a baby in the midwifery using a feminist approach. Methods: This paper is a qualitative research study and applies a feminist epistemology and methodology to the experiences of women who gave birth in midwifery. The data were collected by individual in-depth interviews with eleven participants. Results: Two main themes emerged from the feminist content analyses and each main theme had three sub themes. A. transformation of control and knowledge on childbirth and the body 1) refusing coercive medicalization and building a new normality, 2) specific expectations about biological health and maternity rather than a return to nature, 3) the subject of pregnancy and childbirth, B. 'natural childbirth' practice as a new embodied discipline 1) helpers to support mothers, midwives, 2) helping the body to do 'natural childbirth', 3) from isolated labor to cooperative reproduction. Conclusion: These results indicate that women desired to practice being a subject, consultation with professionals, self-discipline and named actors except for women as 'other subjects' in childbirth.

Objective: The aim of this study was to investigate the strategies for avoiding moving and stationary walker using body segments during walking. Method: Ten healthy young adults (10 males, age: $24.40{\pm}0.49yrs$, height: $175.80{\pm}5.22cm$, body mass: $70.30{\pm}5.22kg$) participated in this study. Each participant was asked to perform a task to avoid collisions with another walker who was moving or stationary during walking on the 10 m walkway. Both walkers were performed at natural self-selected walking speed. Results: Medio-lateral avoidance displacement of the trunk and the pelvis were significantly increased when avoiding a stationary walker (p<.05). There were no significant differences in medio-lateral center of mass trajectory. Rotation angle of trunk, pelvis and foot on the vertical axis were significantly increased when avoiding a stationary walker (p<.05). Conclusion: Based on our results, when another walker moves continuously, the walker recognizes another walker as the object of social interaction and performs the avoidance strategies while expecting the cooperative distance. On the other hand, when another walker is stopped, it is determined that the walker has an obligation to avoid, and the walker performs a relatively safer avoidance strategy.
