Purpose: The purpose of this study was to describe stage distribution of current and former smokers and to analyze significant variables that used by adolescents at each stage using the Transtheoretical Model. Methods: A cross-sectional study was performed with 145 students attended to five high schools in one rural area. The survey instruments included stages and processes of change. decisional balance, self-efficacy, and knowledge related to smoking. Results: Among the participants, 47.6% were in the precontemplation and contemplation stages, 20.7% were in the preparation stage, and the other 31.7% were in the action and maintenance stages. Analysis of variance tests revealed that behavioral processes, pros and cons of smoking, and self-efficacy were significantly associated with the stages of smoking cessation, while among 10 processes of change, self-reevaluation, self-liberation, and reinforcement management were significantly different by the stages. Conclusions: The study results suggest that smoking cessation programs should emphasize behavioral strategies, self-efficacy, and decisional balance to help students adopt and maintain smoking cessation.

Purpose: This study was done to identify the process of change, decisional balance and self-efficacy corresponding to stage of exercise behavior based on the Transtheoretical model in patients with chronic arthritis. Method: The participants were 151 patients with chronic arthritis using an out-patient pain clinic and hospital in C city. The collected data were analyzed using ANOVA, Sheffe test and discriminant analysis with SPSS/WIN. Results: The patients were distributed as follows for each stage of exercise behavior 21.8% in the precontemplation stage, 26.5% in the contemplation stage, 25.2% in the preparation stage, 7.3% in the action stage, and 19.2% in the maintenance stage. Significant effects for stage of change were found for nine of the 10 processes of change and Pros, Cons, self-efficacy. Scores on these variables were found to increase across the stage of exercise behaviors from precontemplation to maintenance. Discriminant analysis revealed that self-efficacy and stimulus control, and reinforcement management were the major correlates of the stage of exercise behaviors. Conclusion: The findings of this study give useful information for exercise intervention, by using strategies of exercise for chronic arthritis patients in different stages of exercise behavior.

Morphological changes of the oviductal epithelium of the rat treated with hormones ($17{\beta}$-estradiol ${\mu}g$/day and progesterone 2.5mg/day) for ten days were observed transmission and scanning electron microscopically. The results obtained were as follows: 1. The cilia formation of ciliary cell(CC) was more accelerated by the treatment of estradiol than progesterone, but the balance of estrogen and progesterone was required for the maintenance of CC. The effect of hormone was different between the segments for the maintenance of CC. 2. The short secretory cell(SSC) was severely inhibited in the formation of secretory granules with single hormonal treatment but the activity of secretion was more inhibited by progesterone than by estradiol. 3. The long secretory cell(LSC) had not a great difference between estradiol and progesterone treatments as compared with the normal sexual cycle, but the formation of secretory granules was somewhat accelerated by progesterone treatment. 4. The formation of secretory granules of junctional cell (JC) was severely accelerated by estradiol treatment as compared with the normal sexual cycle. The formation of secretory granules during progesterone treatment, on the other hand, was inhibited completely, but the numbers of pinocytotic vesicles appeared at the cytoplasmic apical portion. 5. Three types of secretory cells, SSC, LSC and JC, on the rat oviductal epithelium could be suggested to have different cell tapes respectively from the morphological changes by hormone treatment.

Purpose. The purpose of this study was to differentiate the change in exercise behavior into different stages and to investigate differences in the process of change, self efficacy, decisional balances and depression according to the stages of exercise behavior change among middle aged women in Korea by using the transtheoretical Model. Methods. A convenience sample of 434 middle aged women (40-64 years) completed measures of all transtheoretical model constructs involved in exercise behaviors (stages and processes of exercise behaviors change, self efficacy and decisional balance) and depression. The data were analyzed by using the SPSS 10.0 program including descriptive statistics, and one-way ANOVA. Results. The subjects were distributed in each stage of change in exercise behaviors: pre-contemplation (n = 106; 24.4%), contemplation (n = 126; 29%), preparation (n = 88; 20.3%), action (n = 51; 11.8%), and maintenance (n = 63; 14.5%). The processes of change, pros (advantages of behaviors), self-efficacy and depression were significantly differentiated across the stages of exercise behavior change. Cons(disadvantage of behaviors) was not significantly differentiated across the stages of exercise behavior change. Conclusions. Results of this study suggested that discriminating of processes of change, self-efficacy, decisional balance, and depression could provide positive information to people about the stages of change in exercise behavior. Therefore, in designing interventions, the stage of a client's exercise behaviors change needs to be assessed prior to application of intervention programs in order to increase and maintain exercise behavior in middle aged women.

Stance is defined as any state in which the total mass of the body is supported by the feet. In order to maintain stance, the sum of gravito-inertial forces acting on the body must be registered by equal and opposite forces at the region of contact between the organism and the support surface. Balance is controlled by applying forces to the surface of support so as to maintain the body's center of mass vertically above the feet. for a muIti-segment organism, there can be a variety of ways in which balance can be controlled, since movements of different body segments can have similar effects on the control of balance. In general, the organism tends to have a body configuration that is aligned with gravito-inertial force when there are no external forces acting on it. If any segments of the body are not aligned with gravito-inertial force vector, a torque on that segment would tend to move the body's center of mass. The maintenance of postural stability is accomplished in humans by a complex neural control system. This requires organizing integrating and acting upon visual, vestibular, and somatosensory input, providing orientation information to the postural control system. The information necessary to control and coordinate movement is provided by the visual sense of eye position with respect to the surrounding surface layout, the vestibular sense of head orientation in the gravito-inertial space, and the somatic sense of body segment position relative to one another and to the support surface. In this study, perception and action capability was examined from various points of view. The underlying assumption of the study was that the change of postural configuration could be effected by organism, environment and task goal.

Purpose: This study was performed to identify factors associated with drinking behavior using Transtheoretical Model in workers. Method: The study method was a survey of 216 marine shipping metal workers in Koje city from November 11, 2002 to November 30, 2002. Result: The subjects were divided in four stages of drinking behavior: 38.9% in pre contemplation stage, 38.6% in contemplation stage, 17.6% in preparation stage and 7.9% in action & maintenance stage. The amount of drinking was significantly decreased as the workers progressed through each stage. Helping relationships(HR) and Self reevaluation(SR) were identified as the main processes of change in all stages. Self liberation(SEL), Counter conditioning(CC), Helping relationships(HR), Self reevaluation(SR), Dramatic relief (DR) and Social liberation(SL) were used higher than average. The self efficacy score increased as the workers progressed through each stage, but not significantly. The Pros score of decisional balance was the highest in the pre contemplation stage and decreased as the workers progressed through each stage. but not significantly. The Cons score of decisional balance was the highest in the preparation stage, but not significantly in as the workers progressed through each stage. Conclusion: This study can provide the basis of a staged matching alcohol reducing program using TTM for more effective and useful intervention.

Purpose: This review was performed to establish a reference intake of water for Korean (KDRI-water) adults in 2015 by examining current knowledge of the relationship between water intake and health and the general status of water intake and loss. We expect that this study will be utilized for further refinement of KDRI-water. Methods: Documents were searched using RISS, NDSL, DBPIA, CINAHL, and Pubmed with the keywords 'water intake, water supply, water ingestion, hydration, dehydration, water balance, and fluid balance'. Results: Water balance is essential for the maintenance of health. Based on this assumption, numerous studies have been performed to investigate the association of water intake with several diseases such as urolithasis, obesity, diabetes, and cancer as well as other health problems, including constipation, cognition, and fetal weight. Effects of water intake for prevention or relief of these health problems vary. Water is supplied to the body by eating foods and drinking liquids such as plain water and beverages. Metabolic water is another source of water input. Water is lost through urine, skin, respiration, and feces. KDRI-water 2015 was set by adequate intake (AI) based on water intake volume, which was the sum of water intakes from foods and fluids reported by the Korea National Health and Nutrition Examination Survey, with extra milk intake of 200 mL. AIs in some age groups were modified considering their estimated energy requirements. Conclusion: Accurate data of water intake is critically important for the establishment of KDRI-water. Therefore, improvement of systems investigating water intake is required, and more studies on the status of water intake and loss in Korean people are needed for definite KDRI-water establishment.

In the United States, the prospective payment system(PPS), under which diagnosis related groups (DRGs) are used to reimburse hospitals for the care of Medicare patients since 1983, Study results showed that the PPS is having a major impact on the quantity of services especially of hospital length of stay. The PPS has increased the likelihood that a patient will be discharged home in an unstable condition and the use of nursing homes or long term care facilities increased. Still, it is insufficient to conclude that the PPS has decreased the Medicare total expenditure, but relatively sufficient to conclude that the quality of care hasn't changed. The maintenance of the quality resulted from the systemic "check-and-balance" composed of three factors; (1) The doctors are reimbursed based on the fee-for-service system, (2) hospitals contact with doctors under the attending system, and (3) there are some public hospitals. In Korea, the reimbursement for hospitals and doctors are not divided, the hospitals have doctors as employees, and 90% of hospitals are private. These differences may weaken the "check-and-balance" existing in the U.S. system. And there are few long term care facilities and the diagnostic coding system using in pilot test are not suitable for Korean situation. In conclusion, for successful implementation of the DRG payment system in Korea, the government should establish the "check-and-balance" system in the health sector to make sure the quality of care before the implementation.

This study aimed to analyze the correlation between working from home and sleep disorders among domestic workers using data from the 5th Working Environment Survey in 2017. Out of the total 30,108 wage workers, 818 employees work from home and 4,090 work in an office. A random sample of 1:5 pairs, considering gender and occupational group, was selected from these employees as the study subjects. The analysis included personal characteristics, occupational characteristics, work-from-home arrangements, and sleep disorders. Age, education, employment status, years in the workforce, weekly working hours, work-life balance, self-perceived health, depression, and anxiety were all adjusted as potential confounding variables. Conditional logistic regression analysis was conducted to examine the relationship between working from home (independent variable) and sleep disorder (dependent variable). This analysis aimed to analyze the correlation between working from home and sleep disorder. The analysis revealed that working from home was associated with sleep onset latency disorder OR=3.23 (95% CI=2.67~3.91), sleep maintenance disorder OR=3.67 (95% CI=3.02~4.45), and non-restorative sleep OR=3.01 (95% CI=2.46~3.67), which showed a statistically significant relationship with all three types of sleep disorders. Factors influencing the correlation between working from home and sleep disorders included work-life balance, social isolation, and anxiety.
