Objectives: The purpose of this investigation was to study the health status of apartment guards and associated factors. Materials and Methods: This investigation was conducted for 1 month starting from August, 1997. Study population in this cross-sectional survey consisted of 182 guards of apartments located throughout the district of Taegu. Each subject completed a questionnaire about his general characteristics, health behaviors, job descriptions, subjective GIT symptoms and somatization and depression using Symptom Checklist-90-Reversion (SCL-90-R) by self administrated questionnaire and personal interview. Results: Study subjects had one or more GIT symptoms(53.3%), somatization symptoms(83.5%) and depression symptoms(79.7%). The mean scores of GIT, somatization and depression symptoms were not different among the age groups and based on marital status, respectively, but, significantly different by education level(p<0.05). The mean scores of GIT, somatization and depression symptoms were not different among the age group and based on marital status, respectively, but, significantly different by regular diet and by the subject's health status(p<0.05). The mean scores of GIT, somatization and depression symptoms were not different by duration of shift work, by job tenure and by the number of managed houses but, those of somatization and depression symptoms were significantly different by level of job satisfaction(p<0.05). Conclusion: The health statuses of guards at apartments were different from other shift workers because of healthy worker effects and characteristics of their jobs.

The purpose of this study is to verify the mediating effects of psychological flexibility on the relationship between emotional dissonance and mental health(depression, anxiety, somatic symptoms) in university administration staff. For this study, a sample of 191 university administration staff completed the questionnaires. The data was analyzed using the SPSS program and Sobel Test. The results of the analysis are as follows: 1. Most of the university administration staff had difficulties with emotional dissonance(52.36%), depression(47.12%), anxiety(58.12%), and somatic symptoms(62.83%). 2. The risk group of emotional dissonance had a significantly higher level of depression, anxiety and somatic symptoms compared with the normal group. 3. Emotional dissonance and psychological flexibility had a significant effect on depression, anxiety and somatic symptoms. 4. The mediating effects of psychological flexibility on the relationship between emotional dissonance and mental health(depression, anxiety, somatic symptoms) was verified. Finally, We suggested the need to intervene in emotional labor and mental health in university administration staff and psychological flexibility as an intervention and prevention method.

This study was conducted to investigate effects of 12 weeks of combined exercise training with blood flow restriction (BFR) on body composition (weight, %body fat, lean body mass, body mass index (BMI)) and cardiovascular responses (brachial-ankle pulse wave velocity (ba PWV) and ankle-brachial index (ABI)) in elderly women. Participants (N = 43, Females) were randomly assigned into a combined exercise with BFR (n = 14, BFR), only combined exercise (n =14, EX) or non-exercise control group (n = 15, CON). Two-way repeated measures ANOVA with contrast testing was utilized for data analysis. Alpha was set at p < 0.05. Body composition (weight, %body fat, BMI) in BFR was significantly changed, and %body fat in EX was significantly decreased, but there was no change in the CON. In addition, the right and left ba PWV values in the BFR were significantly decreased, while only the left side ba PWV in EX was significantly decreased and there was no change in the CON. Moreover, the % change and effect size of most variables in the BFR were higher than the EX. Taken together, the results indicate that even though BFR and EX groups performed the same combined exercise training, BFR had additional stimulations of the sympathetic nerve system due to blood flow restriction. Thus, BFR training is more beneficial and has greater effects on body composition and cardiovascular responses in elderly females.

Objectives : This study aimed to describe the use of over-the-counter (OTC) drugs and to identify predictors for their use in the elderly living alone. Methods : This is a cross-sectional study that enrolled 1,099 subjects. Data regarding socio-demographic status, medical condition, cognition, mood disorder and use of OTC drugs were collected using self-administered questionnaire and from a specific semi-structured interview by a trained nurse. Data regarding use of OTC drugs were analyzed using descriptive statistics. Logistic regression analysis was applied to examine factors associated with the use of OTC drugs. Results : The use of OTC drugs were reported by 35.4% of the subjects. Analgesics (13.6%) was the most frequent drugs. Depression (OR=1.10, 95% CI=1.10-1.87) and comorbidities measured by cumulative illness rating scale (CIRS) (OR=1.08, 95% CI=1.03-1.12) were significantly associated with the use of OTC drugs in the elderly living alone. Conclusions : Depression and severity of underlying medical conditions could be a predictor of the use of OTC drugs in the elderly living alone. The clinicians should be vigilant regarding the potential use of nonprescription medications in the elderly.

The purpose of this study was to compare the health status, functional status, and home environment hazards by the fear of falling and explore the factors that contribute to the fear of falling. This was a descriptive study. Data were collected for two years with 973 older adults who enrolled in a health center at A city. Trained nurses visited subjects' home and collected data using Resident Assessment Instrument MDS-HC. The average age of the subjects was 76.8 (±7.6) and female was 74.8%. 20.7% of subjects reported fear of falling. In terms of the fear of falling, two groups were compared. There were significant differences in vision, urinary incontinence, pain that interrupts daily activity, unstable gait, comorbidities, frequency of depressive or anxious sign. The greater the age, IADL and ADL dependency, comorbidities, unstabled gait, the more fear of falling. In conclusion, this study reassured the importance of assessing the major factors related to fear of falling such as age, IADL and ADL, comorbities, gait among older adults. This study will contribute to establish strategies for preventing fall. Reducing the fear of falling through the comprehensive nursing intervention will ultimately improve the quality of life in the elderly.

Background : Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for osteoporosis, which has implications for mobility and even mortality. The goal of this pilot study was to evaluate bone mineral density (BMD) and risk factors for osteoporosis in a limited number of men with COPD. Methods : We checked BMD, $FEV_1$(% of predicted) and investigated risk factors for osteoporosis in 44 male patients with COPD who visited our hospital from January to August 2002. Results : Mean(${\pm}$) age was $69{\pm}9$ yrs, body mass index(BMI) $21{\pm}3kg/m^2$, $FEV_1$ $50{\pm}18%$ of predicted, lumbar spine T-score $-3.0{\pm}1.2$, lumbar spine Z-score $-2.0{\pm}1.2$, and lumbar spine BMD $0.76{\pm}0.13g/cm^2$. Osteoporosis(T-score below -2.5) was present in 27 patients(61.4%) and osteopenia(T-score between -1 and -2.5) in 17(38.6%). None of the patients had normal BMD. There was no relationship between BMD and $FEV_1$(% of predicted). There were significant differences in smoking, alcohol consumption, exercise, cumulative steroid dose, BMI and BMD among the three groups according to $FEV_1$(% of predicted) (group1 : ${\geq}65%$, group2 : 50-64%, group3 : ${\leq}49%$), except age. However, there were no significant differences in these variables between the osteopenia and osteoporosis groups, except BMI. Linear Regression(Stepwise) analysis showed that lumbar BMD was correlated with BMI & exercise. Conclusion : BMD is significantly reduced in men with COPD. There was no relationship between BMD and pulmonary function.

Public officials are volunteers for the people, and the police are in charge of the safety of the people. In particular, the marine safety of Korea, which has three sides of the sea, is very important. The education of maritime police is a very important factor due to the specificity and risk of the sea. In particular, since the new curriculum is linked to the job while in office, factors related to educational performance are more important. In this study, the relationship between personality characteristics and academic burnout was examined for 200 new maritime police officials. Among the five factors of personality characteristics, extroversion factors, neurotic factors, and emotional exhaustion factors were extroversion factors, neurotic factors, and cynicism factors, and extroversion factors, neurotic factors, and integrity factors. In particular, the five factors of personality characteristics that have the greatest influence on academic burnout were neurotic. For the educational satisfaction and effectiveness of the new maritime police officer, it is necessary to minimize the psychological margin and stress of the new maritime police officer.

Objectives : Somatic symptom disorder (SSD) is characterized by the manifestation of a variety of physical symptoms, but little is known about differences in autonomic nervous system activity according to symptom severity, especially within patient groups. In this study, we examined differences in heart rate variability (HRV) across symptom severity in a group of SSD patients to analyze a representative marker of autonomic nervous system changes by symptoms severity. Methods : Medical records were retrospectively reviewed for patients who were diagnosed with SSD based on DSM-5 from September 18, 2020 to October 29, 2021. We applied inverse probability of treatment weighting (IPTW) methods to generate more homogeneous comparisons in HRV parameters by correcting for selection biases due to sociodemographic and clinical characteristic differences between groups. Results : There were statistically significant correlations between the somatic symptom severity and LF (nu), HF (nu), LF/HF, as well as SD1/SD2 and Alpha1/Alpha2. After IPTW estimation, the mild to moderate group was corrected to 27 (53.0%) and the severe group to 24 (47.0%), and homogeneity was achieved as the differences in demographic and clinical characteristics were not significant. The analysis of inverse probability weighted regression adjustment model showed that the severe group was associated with significantly lower RMSSD (β=-0.70, p=0.003) and pNN20 (β=-1.04, p=0.019) in the time domain and higher LF (nu) (β=0.29, p<0.001), lower HF (nu) (β=-0.29, p<0.001), higher LF/HF (β=1.41, p=0.001), and in the nonlinear domain, significant differences were tested for SampEn15 (β=-0.35, p=0.014), SD1/SD2 (β=-0.68, p<0.001), and Alpha1/Alpha2 (ß=0.43, p=0.001). Conclusions : These results suggest that differences in HRV parameters by SSD severity were showed in the time, frequency and nonlinear domains, specific parameters demonstrating significantly higher sympathetic nerve activity and reduced ability of the parasympathetic nervous system in SSD patients with severe symptoms.

Objectives: This study was done to find out fatigue and self-reported physical symptoms of Vinylhouse farmers. The results of this study could be used as a basic data to develop health promotion program for Vinylhouse farmers who are suffering from fatigue and physical symptoms. Methods: The 166 respondents, who were working in Vinylhouse and were living in a remoted area where the primary health post located, were participated in this study. Thirty: 30 items of self-reported fatigue scale was used to evaluate the farmers fatigue level which made by Japanese industrial and hygenic association(1988). Twenty four: 24 items of index used by researcher for self-reported physical symptoms was from Lee In Bae's(1999) modified Index which was originated from Cornell Medical Index(1949). Another questionnaires used in this study were developed by researcher through related documents. Results: The results of this study were as follows; Fatigue scores were high in accordance with women(t=-2.212, p<0.05), worse recognized health state(F=20.610, p<.001), lack of sleeping hours(F=3.937, p<0.05), eat irregularly(t=-3.883, p<0.001), don't take a bath after application of chemical(t=-2.950, p<0.01), working time per a day(F=5.633, p<0.01) & working time per a day in Vinylhouse(F=5.247, p<0.01) were long. Subjective physical symptoms were high in accordance with women(t=-3.176, p<0.01), worse recognized health state(F=35.335, p<0.001), and low education(F=3.467, p<0.05). eat irregularly(t=-3.384, p<0.01), alcohol drinking(t=-2.389, p<0.05). When farmers don't take a bath after application of chemical show high(t=-3.188, p<0.01). As a result, the factors affecting to Vinylhouse worker's health were irregular diet habit, scarce exercise, lack of proper rest, symptoms oriented from Vinylhouse work in contaminated environment with high temperature and humidity. Conclusions: Based on this study, health promotion program is necessary for Vinylhouse workers. Also, the development of continuously practical strategy of healthy life style including exercise and comprehensive health promotion program considered the country's social and cultural background are needed.

The purpose of this study was to investigate relations among the quality of life, health states, physical functions, cognitive functions, and social supports of the elderly at care facilities. The subjects include the elderly that were living in care facilities in some urban areas and aged 65 or older. The data of total 260 old people were used in analysis. Collected data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation, and stepwise multiple regression. The elderly at care facilities, who were considered as physically and cognitive vulnerable, scored higher means on quality of life when they were satisfied with the length of stay and sleeping state, had higher subjective health states, had no tooth inconvenience and forgetfulness, suffered from a lower level of depression, had better cognitive functions, and received higher social supports. Quality of life had correlations with the sleeping state(r=-.20, p<.001), subjective health state(r=-.24, p<.001)s, depression(r=-.30, p<.001), and social supports(r=.30, p<.001). Social supports(${\beta}=.30$, p<.001), depression(${\beta}=-.25$, p<.001), subjective health states(${\beta}=-.22$, p<.001), length of stay(${\beta}=-.22$, p<.001), and sleeping state(${\beta}=-.12$, p=.025) turned out to predict the quality of life of the elderly at care facilities and have close relations with it. In short, the quality of life of the elderly is related to many different factors at care facilities. The findings indicate that nursing interventions and managements for quality of life require a mental and social approach or a whole person approach with a focus on the understanding of individual senior citizens rather than on physical activities and diseases.
