Oak, Ji Won,Lee, Hea Shoon 한국간호과학회 2012 Journal of Korean Academy of Nursing Vol.42 No.7
Purpose: The purpose of this study was to verify prevalence rates of atopic dermatitis (AD) in middle school students in Korea and to define AD and associated factors. Methods: This study was conducted using secondary analysis of raw data from the ‘The 6th Korean National Adolescent Health Behavior Survey, 2010’ conducted by the Korea Centers for Disease Control. The participants were 37,570 students. General characteristics and health behavior-related characteristics were analyzed using descriptive statistics, χ²-test and logistic regression analysis. Results: Results are as follows. 1. There were 8,494 middle school students (22.6%), who had been diagnosed with AD during the last 12 months. 2. Factors associated with AD in middle school students were gender (p<.001), grade level (p=.001), father’s education (p<.001), mother’s education (p=.032), regular dietary habits (breakfasts, p=.025; lunches; p=.003), stress (p<.001), recognition of subjective awareness of one’s health conditions (p<.001), hand washing before meals at school (p=.013), and cessation education for both smoking (p=.002) and alcohol (p=.031). Conclusion: Results of the study indicate that in order to alleviate AD symptoms in these students, there is a need to develop nursing interventions and education programs taking into consideration these variables and verifying the effects of interventions and programs.

High frequency ventilation techniques re accepted for upper airway and intrathoracic surgery under general anesthesia, Good oxygenation and ventilation are achieved with good airway control and operative conditions. However, the jet ventilating system is of an open character with mandatory use of intravenous anesthesia. The present study was done to administer inhalation anesthetics (halothane) during high frequency ventilation. The high frequency injector was adapted to an angiocatheter with a swivel connector, while the entrainment orifice of the side port was connected to the anesthesia circuit to facilitate the administration of inhalation anesthetics. Variables thought to be important in determing the inspiratory peak halothane concentration and diluting inspiratory oxygen concentration for estimation of gaseous influx from the anesthesia circuit were evaluated in an experimental lung model. Changing the halothane concentration of the vaporizer(1,3,5%), ispiratory: expiratory (I:E) ratio(0.2: 0.2, 0.2: 0.4, 0.2: 0.6, 0.2: 0.8, 0.2: 1.0 sec.). driving gas pressure(DGP) (10,30,50 psi), the inspiratory peak halothane and oxygen concentration were measured, The results were analyzed to predict the association and relationship of the inspiratory peak halothane and oxygen concentration with each variable. Partial coefficient of halothane concentration of the vaporizer, I:E ratio, DGP were 0.7224,0.3724,0.3386 and R squares were 0.5219,0.6605, 0.7752 to the inspiratory peak halo- thane concentration. Partial coefficient of I:E ratio, DGP were- 0. 9386, 0.1138 and R squares were 0.8809,0.8939 to the inspiratory oxygen concentration, Halothane concentration of the vaporizer was the most associated factor to the inspiratory peak halothane concentration and I:E ratio to the inspiratory oxygen concentration. Clinically, if DGP and I:E ratio are determined, the halothane concentration of the vaporizer will be the predictor of the inspiratory halothane concentration. But in a. certain condition, the inspiratory peak halothane concentration could at be achieved to a proper level for maintaining anesthesia by this experimental model, In conclusion, most of the high frequency jet systems used clinically are of the open character allowing entrainment of additional gases and difficult to apply if volitile agents are to be used. Special predictable vaporiiers have to be developed to apply volitile agents in any situation of I:E ratio and DGF by this method of administering inhalation agents during high frequency jet ventilation.

Oak, J. S., Choi, IS., Jun, T.W., Eom, W.S. The Effect of Weight Training on continuous Response Time in Male Fencing Players. Exercise Science, 11(1): 221-231, 2002. The purpose of this study was to investigate the effect of 8-week weight training on continuous response time. To achieve this purpose subjects were 30 colleges male fencing players who have not medical diseases, were divided into experiment group and control group. The muscle fitness was measured by 1㎏ unit of weight equivalent to 20RM of weight training items respectively, muscle fitness of pre weight training program treatment was compared with those of post weight training program treatment. Also response time of two basic motions of fencing forward movement-fente were measured by a self-produced response time measuring instrument, and continuous response time, reaction time, movement time of pre and post weight training program treatment during fencing forward movement-fente motion were inspected comparatively. The results of this study were as follows. First, muscle endurance and continuous response time of fencing players were correlated in significantly. Two, after 8 weeks weight training program, continuous response times, reaction time, and movement time between experiment group and control group were showed significant difference. As this results, muscle endurance was closely related to continuous response time, weight training program developed on the basis of this had an affirmative effect on continuous response time, reaction time, and movement time of the basic movement of a fencing.
