This study attempted to identify obese students' stress and coping method in middle and high schools. The data were collected from the total of 600 obese students from middle and high schools in Pusan. The author used a convenience sampling method. The data collection was done from March 2 to April 30. 2001. The analysis of the data was done with SPSS Win(10.0) for descriptive statistics. t-test. and ANOVA. The instrument used for the obese students' stress and coping method was a questionnaire developed by Kim. Yi-Soon and Kim. Young-Hae(200l). The tool was composed of 65 items (33stress items: 32coping method items) with the five-point Likert scale. The results were as follow: 1. The average score of stress was 2.49 (SD = .86) points in the male students. and 2.83(SD= .86) points in the female students. The subcategories were: (outward appearance), (boyfriend/girlfriend), (occurrence of an outbreak of a disease), (relationship within the family), (an obese appearance), (difficulty in exercise). The highest degree of stress came from 'an obese appearance' for the male students (mean=2.64. SD=0.87) and (mean=2.64. SD=0.87) for the female students. 2. The subcategories of the coping method were: (be concerned about other matters), (recreation activities), (self-violence), (relaxation), (hobby activities), (avoid a situation), (communication), (music), (negative behavior), (positive thinking). The highest degree of coping method were (recreation activities) in the male students (mean=3.07. SD=0.86) and (music) in the female students (mean=3.47. SD=1.01). 3. The results comparing stress with demographic variables were significant for gender (t=7.010. p=0.000). grades at school (F=2.918. p=0.02l), degree of obesity (F=5.205. p=0.006). grades (F=2.550. p=0.027). standard of living(F=8.277. p=0.000). the state of health (F=2.882, p=0.022), relationship with the father (F=4.790, p=0.001), relationship with the mother (F=6.080, p=0.000), and the educational level of the father (F=3.192, p=0.013). 4. The results comparing the coping method with demographic variables were significant for gender (t=4.597. p=0.000). These findings contribute to the understanding of the degree of stress and the type of coping methods of obese students in middle and high schools. Therefore, the result of this study aids in an effective nursing intervention to improve the mental health program for the obese.

This paper attempts to identify the occupational stress-related factors among the workers at the manufacturing industry and to provide the basic data concerning development of stress management program focused on the manufacturing industry. The subjects exhibit significantly highest level of 'the characteristics of task and participation in decision making factor'. And the mean score of 'the avoid coping strategies' was higher than 'the control coping strategies'. The main factor that affected the occupational stress responses was 'the physio-environmental factor' and it was explained 15.6% out of the total variance of the stress responses. Also, it would be explained 29% out of the total variance of the stress responses with 'the characteristics of task/participation in decision making factor', sex, social support, and 'extra-organizational stressor'. In conclusion. For developing the stress management program in workplace, 'the physical environmental factor' and 'the characteristics of task and participation in decision making factor' should be considered. Also, It should be identified the direct and indirect paths among factors that significantly related factors to the occupational stress of workers further more.

A mobile robot should be designed to navigate with collision avoidance capability in the real world, coping with the changing environment flexibly. In this paper, a novel navigation method is proposed for fast moving mobile robots using limit-cycle characteristics of the 2nd-order nonlinear function. It can be applied to robots in dynamically changing environment such as the robot soccer. By adjusting the radius of the motion circle and the direction of the obstacle avoidance, the mobile robot can avoid the collision with obstacles and move to the destination point. To demonstrate the effectiveness and applicability, it is applied to the robot soccer. Simulations and real experiments ascertain the merits of the proposed method.

Purpose: This study aimed to determine health problems experienced by workers in special employment relationships (WSER) and identify coping strategies used when such problems occur. Methods: This qualitative study used the focus group interview method. Thirteen study participants included five home-visit tutors, five insurance salespersons, and three credit card recruiters. The interviews were conducted from November 2018 through January 2019, with each occupational group interview lasting about 2 hours. Analysis based on phenomenological research was independently performed by two researchers. Results: Most participants had common health problems involving vocal cord symptoms, and stress related to emotional labor and traffic accidents. The unique health problems included cystitis, musculoskeletal, and digestive symptoms in home-visit tutors; reduced vision and hearing in insurance salespersons; and mental distress in credit card recruiters. There was no protection system for their health coverage, and the company emphasized their self-employed status to avoid taking responsibility for them. Twelve participants did not purchase occupational accident insurance owing to both not having adequate information and economic burden concerning premium status. Conclusion: WSER experienced both physical and mental health problems. These problems were caused by their unstable employment status, and the social security system for their coverage being non-functioning.

Purpose: Purpose of this study was to explore the process of menopause experiences in middle-aged women. Method: The grounded theory methodology by Strauss & Corbin was the basis for this study. The participants were 15 middle-aged women selected by theoretical sampling. The data were collected by in-depth interviews using audiotape recording analyzed simultaneously by the constant comparative method described in Strauss and Corbin's methodology. Results: Experiencerelated to menopause in middle-aged women is caused by cognition of the aging process, difficult problems in family that occur with limitation of social activity, and perception of changingseasons. The central incident of menopause in middle-aged women was loss of the woman's identity. Intervening conditions, which are action/interactional strategies for menopause, are related to social support. Action/interactional strategies related to menopause management included medical treatment, mind control, and participation in social activity. Experiencerelated to menopause in middle-aged women resulted in comfort or discomfot of physical and emotional condition. Conclusion: The findings of this study may contribute to the development health promotion strategy for middle-aged women. There is need to develop family support systems and preventive nursing interventions to avoid negative coping strategy.

What was once known as common courtesy is rapidly disappearing in the air travel industry, and the violent behavior known as air rage is a constant threat. Once sought after by other industries for advice because of its expertise in customer service, the air travel industry has now slipped to the lowest rungs of companies with unhappy customers. As airlines cut corners in order to avoid bankruptcy, passengers' patience is tested by the stress of flight delays, crowded airports and close packed seating on airplanes. This article examines the situation, strategies used by passengers and ways the airline industry might better inspire courteous behavior in passengers. A cultural expectation of entitlement and competitiveness for limited resources has led to a breakdown in civilized behavior throughout society, both in the United States and internationally. Air travelers faced with rude and intrusive behavior from others on the flight are beginning to find their own ways of coping, such as high quality headphones to block offensive noises, and mechanical devices to keep the seat in front from reclining to the point where it hits their knees. The most potentially effective remedies will come from airlines that enlist cooperation by offering effective passenger education and possibly even incentives. Acceptable airline behaviors need to be plainly defined and stressed for passengers, both before boarding and onboard. In this paper, some methods are suggested to motivate passengers and to inspire courteous behavior.

The use of screw-retaind prosthesis on an osseointegrated implant is a popular treatment modality offering relative ease in the removal of the restoration. One of the complications associated with this modality is the loosening of the abutment and coping screws. Loosening of the screws results in patient dissatisfaction, frustration to the dentist and, if left untreated, component fracture. There are several factors which contribute to the loosening of implant components which can be controlled by the restorative dentist and lab technician. This article offers pratical solutions to minimize this clinical problem and describes the factors involved in maintaining a stable screw joint assembly. To avoid joint failure, adherence to specific clinical, as well as mechanical, parameters is critical. With respect to hardware, optimal tolerance and fit, minimal rotational play, best physical properties, a predictable interface, and optimal torque application are mandatory. In the clinical arena, optimal implant distribution; load in line with implant axis; optimal number, diameter, and length of implants; elimination of cantilevers; optimal prosthesis fit; and occlusal load control are equally important.

Fault-tolerant gait planning in legged locomotion is to design gaits with which legged robots can maintain static stability and motion continuity against a failure in a leg. For planning a robust and deadlock-free fault-tolerant gait, kinematic constraints caused by a failed leg should be closely examined with respect to remaining mobility of the leg. In this paper, based on the authors's previous results, deadlock avoidance scheme for fault-tolerant gait planning is proposed for a hexapod robot walking over even terrain. The considered fault is a locked joint failure, which prevents a joint of a leg from moving and makes it locked in a known position. It is shown that for guaranteeing the existence of the previously proposed fault-tolerant tripod gait of a hexapod robot, the configuration of the failed leg must be within a range of kinematic constraints. Then, for coping with failure situations where the existence condition is not satisfied, the previous fault-tolerant tripod gait is improved by including the adjustment of the foot trajectory. The foot trajectory adjustment procedure is analytically derived to show that it can help the fault-tolerant gait avoid deadlock resulting from the kinematic constraint and does not make any harmful effect on gait mobility. The post-failure walking problem of a hexapod robot with the normal tripod gait is addressed as a case study to show the effectiveness of the proposed scheme.
