Purpose: The purpose of this study was to examine the effect of a multifactorial program for urinary incontinence, self-esteem and self-efficacy in older women. Methods: A one-group pretest-posttest with no control group was used. Nineteen women completed weekly 90-min group sessions for eight weeks. The group received a multi-factorial program comprised of Kegel exercise, education and psychosocial programs over 8 weeks. Data on urinary incontinence, self-esteem and self-efficacy were collected twice: before the intervention and 8 weeks after the intervention. Data were analyzed using paired t-test by non-parametric statistics. Results: Total scores for the International Consultation on Incontinence Questionnaire decreased significantly after the intervention (pretest $7.95{\pm}5.48$, posttest $5.15{\pm}4.72$, p<.05). The scores for self-esteem and self-efficacy improved significantly. Conclusion: These results indicate that a multifactorial program for older women is feasible to prevent urinary incontinence in women living in the community.

There are few studies reporting optimal waist circumference that can be utilized to prevent the incidence of cardiovascular disease (CVD). We evaluated the association of waist circumference and waist and hip circumference ratio (WHR) with incident cases of CVD developed over 6 years in a population-based prospective study including Korean adults. Analyses for receiver-operating characteristic (ROC) curve were performed with data for 1,733 men and 1,579 women who were aged 40 to 69 years and were free of a physician-diagnosis of CVD at baseline. Information on the diagnosis of CVD was periodically reported using interviewer-administered questionnaires and anthropometric measures were obtained by biennial health examinations. We newly identified 77 cases of CVD during a follow-up period between 2003 and 2008. On the basis of measures of diagnostic accuracy including minimum distance to ROC curve and Youden index, waist circumference of 85 cm for men, in particular for male nonsmokers, and of 80 cm for women and WHR of 0.88 to 0.90 for men and of 0.83 for women were found to be optimal cutoff points to identify individuals at CVD risks. The study also found that the use of the suggested optimal values for waist circumference show higher sensitivity and lower specificity compared with 90 cm for men and 85 cm for women, which are waist cutoff points given by the Korean Society for the Study of Obesity to define abdominal obesity for Korean adults. Although lower cutoff points of waist circumference (83 cm) and WHR (0.87) were observed to be optimal for male smokers compared with male nonsmokers, whether suggesting waist cutoff points specific to smokers is needed warrants further studies. After taking into account other cardiovascular risk factors including smoking, men with waist circumference of 85 cm or greater and women with 80 cm or greater were at an increased risk of CVD. Thus, these cutoff points of waist circumference may be able to capture more individuals at CVD risks contributing to the prevention of future development of CVD.

Background: Integrated management of general, mental, and oral health is necessary to improve an individual's quality of life. This study aimed to identify the effects of mental and oral health behaviors on metabolic syndrome. Methods: A total of 4,227 Korean adults aged 20 years or older were selected as study subjects using raw data from the first year (2019) of the 8th period of the Korea National Health and Nutrition Examination Survey (KNHANES). A complex sample chi-square test and a complex sample logistic regression analysis were performed using the PASW Statistics ver. 18.0 program. Results: The effect on metabolic syndrome was significantly higher in male than in 1.833 times in male, 2.914 times in 30~49 years old, and 3.855 times in 50~64 years old, and 3.929 times in people over 65 years old compared to 20~29 years old, and compared to those with a college degree or higher, those with a middle school degree or lower are 2.116 times, those with lower income levels are 1.507 times higher, those with middle-lower are 1.359 times higher, those with middle-high are 1.401 times. Compared to non-smokers, smokers were 1.570 times higher than non-smokers and compared to those without speech problem and chewing difficulty, they were 1.717 times and 1.397 times higher, respectively and 1.973 times higher in those with 0~1 brushing times per day. Mental health did not affect prevalence of metabolic syndrome. Conclusion: It is necessary to improve maintain a healthy lifestyle to lower the risk of metabolic syndrome. It is necessary to establish effective dental hygiene customized education and an efficient health management system at the national level that can induce improvement of oral health behavior for the prevention and management of metabolic syndrome.

The goal of this article is to estimate the change in plasma catecholamine when ST-36 (Leg Three Li) and HT-7 (Spirit Gate) among the meridian points were stimulated for the group of the young and the old, using SSP therapy, thereby clarifying its effects on the responses of catecholamine that generates various physiological effects on the body, in particular, the effects on catecholamine, in the senile body, thereby providing its availability for physical therapy for the old, which is now the major concern of the society. As for research subjects, a total of 10 healthy male and female adults in their twenties were selected as the group of the young, and 10 old male and female, aged over 60, as the group of the old. The findings are as follows: When SSP stimuli were applied to ST-36 and HT-7, as for the change in the content of plasma catecholamine for the group of the young, norepinephrine significantly increased from $309.40{\pm}23.81pg/ml$ before stimulation to $374.90{\pm}35.31pg/ml$ 20 minutes later and to $406.70{\pm}42.43pg/ml$ 40 minutes later (P < 0.05); epinephrine significantly increased from $100.70{\pm}28.55pg/ml$ before stimulation to $95.70{\pm}24.16pg/ml$ 20 minutes later and to $128.80{\pm}25.02pg/ml$ 40 minutes later (P < 0.05); and dopamine showed no significant differences as its content was $245.20{\pm}40.01pg/ml$ before stimulation, $233.50{\pm}59.56pg/ml$ 20 minutes later and $250.90{\pm}56.13pg/ml$ 40 minutes later.

In the laboratory study, the toxicities of chlorpyrifos-methyl, chlorpyrifos, etofenprox, etofenprox+PAF' and deltamethrin for different larval instars of S. litura decreased significantly as larvae aged. LCso values for chlorpyrifos- methyl and chlorpyrifos increased significantly from 3rd instar larvae, while those for etofenprox+PAP and deltamethrin-increased from 2nd instar larvae. In pot study, no significant differences in control efficacy were observed among each treated plots and over 90% control efficacy at 5 d after treatment was obtained in all of the treated plots, except treatment with deltamethrin. Therefore four insecticides excluding deltamethrin will be effective for controlling S. litura. However, it will be probably important to select appropriate insecticides and decide a proper time of treatment because the developmental stage is a significant factor in deciding insecticide efficacy because various developmental stages of the tobacco cutworm inhibit in fields.

This research was conducted to design and develop a wired monitoring system for judging if sick or dead layers (SDL) exist in multi-tier layers battery (MLB) by machine vision, and to analyze its performance. In this study, 20 Brown Leghorn (Hi-Brown) layers aged 37 weeks old, were used as the experimental animals. The intensity of concern paid by layers on feed was over 90% during 5 minutes and 30 seconds after providing feed, and normal layers (NL) had been standing to take feed for that period. Therefore, in this study, the optimal judging time was set by this test result. The wired monitoring system developed was consisted of a driving device for carrying machine vision systems, a control program, a RS232 to RS485 convertor, an automatic positioning system, and an image capture system. An image processing algorithm was developed to find SDL in MLB by the processes of binary processing, erosion, expansion, labeling, and reckoning central coordinate of the captured images. The optimal velocity for driving unit was set up as 0.13 m/s by the test results for wired monitoring system, and the proximity switch was controlled not to be operated for 1.0 second after first image captured. The wired monitoring system developed was tested to evaluate the remote monitoring performance at lab-scale laying hen house. Results showed that its judgement success.ate on normal cage (without SDL) was 87% and that on abnormal cage (with SDL) was 90%, respectively. Therefore, it would be concluded that the wired monitoring system developed in this study was well suited to the purpose of this study.
