  • Purpose: Hwabyung is a culture-bound syndrome in Korea, characterized by emotional stress such as anger, depression, and anxiety. The purpose of the present study was to explore the characteristics of Hwabyung patients, based on constitutional medicine, for their symptoms, duration, and coping styles. Method: Participants were 57 Hwabyung patients selected by Hwabyung criteria. They were also diagnosed for their constitution by doctors specialized in constitutional medicine. Each participant was asked to respond to a variety of items such as cause and duration of stress, symptoms of hwabyung, anger and depression, and coping styles. Eight patients were excluded from the total sample; two male patients and six patients unable to be diagnosed for any particular type of constitution. Thus, final sample was 49 female hwabyung patients, which will be reported in what follow. Result: To begin with, constitutional type revealed significant differences in such coping styles as 'perseverance,' 'positive interpretation,' 'positive comparison,' and 'emotional pacification.' More specifically, post-hoc comparison revealed that Taeeumin(person who have taeeum characteristics) was higher in 'perseverance' compared-to other two types of constitution. Taeumin also revealed higher score than Soeumin(person who have soeum characteristics) in 'positive comparison.' With respect to the marital status, the married compared to the unmarried showed higher score in 'anger-control,' and lower score in 'anger-in.' The married compared to the unmarried, regarding coping styles, also showed higher score in 'accommodation,' but lower score in 'emotional expression.' The duration of hwabyung revealed that the longer duration of hwabyung, the more frequent utilization of 'positive interpretation' and 'emotional pacification. Conclusion: The main purpose, the exploration of hwabyung based on four types of constitution, was not supported, as a whole in the present study. However, marital status and duration of hwabyung appear to influence on emotional stress (e.g., anger) as well as coping styles, suggesting that these variables should be dealt with in future studies on hwabyung.

  • With the reduction of contagious diseases throughout the world and prolonged life expectancy has lead into increase of habitual related diseases. Industrial development and better economic situation made people more concerned about their health. As primary illnesses are subdued in the past years, health care system and the public value prevention and well-being more than the treatment itself. Based on this trend, this study focused on the view of life from the perspective of Oriental medicine as it's peculiarities, regimen methods, and the definition of healthy life are evaluated. Following results were obtained: - View of life in Oriental medicine focused on two basic principles of interrelationship between the organs internally, inter-dependency with the natural environment and social surrounding externally as recognition and respect between the medium were valued. - Sustaining and maintaining good health in Oriental medicine are closely related to prenatally healthy pregnancy and fetation, as well as prenatal training. Postnatal maintenance includes accommodation to seasonal changes, adequate food intake, mind control, various regimen methods and avoidance of wrong doings. - Defining health includes body's internal condition and external influences, principles of essence, qi, spirit, and yin and yang, harmony and balance, and individuality. - To conclude, good health in Oriental medicine is defined as 'external adaptation to society and natural environment, and internal balancing of individual difference with accumulation of essence, nurturing and circulating qi, and every material around the body in harmony and balance."

  • Objective: The purpose of this study was to investigate differences of shock attenuation strategies between double-leg and single-leg landing on sagittal plane using statistical parametric mapping. Method: Nine healthy female professional soccer players (age: 24.0±2.5 yrs, height: 164.9±3.3 cm, weight: 55.7±6.6 kg, career: 11.2±1.4 yrs) were participated in this study. The subjects performed 10 times of double-leg and single-leg landing from the box of 30 cm height onto force plates respectively. The ground reaction force, angle, moment, angular velocity, and power of the ankle, knee, and hip joint on sagittal plane was calculated from initial contact to maximum knee flexion during landing phase. Statistical parametric mapping was used to compare the biomechanical variables of double-leg and single-leg landing of the dominant leg throughout the landing phase. Each mean difference of variables was analyzed using a paired t-test and alpha level was set to 0.05. Results: For the biomechanical variables, significantly increased vertical ground reaction force, plantarflexion moment of the ankle joint, negative ankle joint power and extension moment of the hip joint were found in single-leg landing compared to double-leg landing (p<.05). In addition, the flexion angle and angular velocity of the knee and hip joint in double-leg landing were observed significantly greater than single-leg landing, respectively (p<.05). Conclusion: These findings suggested that negative joint power and plantarflexion moment of the ankle joint can contribute to shock absorption during single-leg landing and may be the factors for preventing the musculoskeletal injuries of the lower extremity by an external force.

  • Wet clutches in an automatic transmission enable the transmission of the engine power by the frictional torque experienced and noted between disk and plates. Since the clutch frictional torque considerably affects the shift quality of an automatic transmission as well as the durability of the machinery, its friction characteristics must be carefully examined to meet the design requirements. The SAE No. 2 friction test machine is a well-known standard to evaluate mainly the friction characteristics of plate clutches along with the required automatic transmission fluids. This paper reviews the experimental analysis of the wet clutch friction characteristics by using the exclusively developed clutch test machine which is capable of controlling the clutch test procedure, in accordance with the applicable test standard and processing of the experimental data automatically. As the clutch test machine is designed for the accommodation of dual clutches which is applied to the real transmission, it can evaluate not only the clutch friction characteristics, but also an actuation performance of a measured clutch piston. In respect to friction characteristics involving dynamic friction coefficients, the energy absorbed in a clutch disk and the recorded temperatures of clutch plates during braking actions and procedures are also investigated. Additionally, the change of friction coefficients by the use of the repeated clutch application is also observed with the endurance test functions of an accurately calibrated and dedicated clutch test machine.

  • A bunker bed is a type of furniture that efficiently utilizes a narrow indoor space by having a high bed and using the empty space below as a living and storage space. The demand for multi-purpose furniture is increasing due to the recent increase in single-person households and wide-spread shared accommodation. According to the consumer research, one of the major drawbacks of a bunker bed was to get on and off the bed through a ladder or stairs. In order to overcome these problems, it was confirmed that the height adjustment function that can easily adjust the minimum and maximum heights of the bed was necessary. In this study, a height adjustable bunker bed was designed by using a gas spring that generates a repulsive force by the compressed gas inside. The design process consisted of the following three steps: Firstly, the hysteresis characteristics due to a friction and spring constant of a commercial gas spring were confirmed by measuring the repulsive force vs. compressed displacement. Secondly, requirements of the vertical lifting force exerted on the bed against gravity force were derived. Finally, the height-adjustable bed using the four-bar link mechanism was designed with 4 parameters so that the bed weight of 60-70 kgf could be adjusted to 800 mm in height by an affordable initial operation force. The performance was verified through prototype production and the results of vertical displacement and force to move were nearly the same as designed. In addition, an electrically operated height-adjustable bed was also designed with linear actuators and the performance was proved with the prototype.

  • Purpose: Walking practice is a representative indicator of the level of physical activity of local residents. Although the world health organization addressed reduction in prevalence of insufficient physical activity as a global target, the rate of walking practice in Korea has not improved and there are large regional disparities. Therefore, this study aimed to explore the spatial variations of walking practice and its associated factors in Korea. Methods: A secondary analysis was conducted using Community Health Outcome and Health Determinants Database 1.3 from Korea Centers for Disease Control and Prevention. A total of 229 districts was included in the analysis. We compared the ordinary least squares (OLS) and the geographically weighted regression (GWR) to explore the associated factors of walking practice. MGWR 2.2.1 software was used to explore the spatial distribution of walking practice and modeling the GWR. Results: Walking practice had spatial variations across the country. The results showed that the GWR model had better accommodation of spatial autocorrelation than the OLS model. The GWR results indicated that different predictors of walking practice across regions of Korea. Conclusion: The findings of this study may provide insight to nursing researchers, health professionals, and policy makers in planning health programs to promote walking practices in their respective communities.
