Objectives: The aim of the present investigation was to determine whether the finger photoplethysmography (PPG) of the young will become analogous to those of the old when the PPG harmonic components in the young decrease. Methods: The PPG was measured in 46 old men (21 males and 25 females) over the age of 60 years and 10 young men (5 males and 5 females). We acquired the representative pulse waveform of old men by averaging the PPG waveforms measured in the old men. after the PPG harmonic components in the young men were diminished with notch filtering, we compared the representative pulse waveform of old men and those of the young men. Results: The PPG waveform of the young males became analogous to the representative pulse waveform of the old as the PPG harmonic components in the young were diminished with notch filtering. Especially after the second harmonic component in the young was diminished with notch filtering, increase of the Pearson's correlation coefficient was prominent. On the other hand, the Pearson's correlation coefficient between the PPG waveforms of the young females and that of the old deceased after the second harmonic component diminished in the young. Conclusions: Decrease of the second harmonic component may be a precondition of typical age-related change of the pulse waveform in the healthy male.

The purpose of this study is to investigate the changes of modern Korean men's fashion from the 1960s to the 1990s by reviewing fashion magazine advertisements and pictorials. For theoretical study, the characteristics and the importance of apparel advertisements and the changes of modern Korean men's fashion trend were reviewed. On the basis of the theoretical investigation, this study analyzed 932 pictorials from Joongang Magazine, Shin Dong-A, Bokjangwolbo, Meot, Men's Life, WWD, and S.F.F.A's photograph album, published from 1962 to 1998. Content analysis method was used to analyze the content of magazines and pictorials. The 932 samples are classified into apparel types, silhouette, pattern, color, type of breasts, shape of collar, number of button, type of inner wear. Frequency and $x^2$-test were conducted using a SAS statistics package to analyse the data. The results were as follows. The two-piece style prevailed in men's wear during the 60s, 70s, and 90s, while separate style prevailed during the 80s. H silhouette was the most popular during the 60s, 70s and 90s, however, X silhouette dominated the 70s. For patterns, solids were most frequently used throughout the whole 4 decades. In colors, gray was most frequently used during the 60s, and multi color was most frequently used during the 70s, 80s, and 90s. Throughout the whole decades, single breast, tailored collar, two buttons, and dress shirts were the most prevalent styles.

Objectives : To determine the relationship between exercise and the incidence of type 2 diabetes in an impaired fasting glucose group. Methods : This prospective cohort study was conducted in 19,440 men and 4,297 women, aged 30-69 years, with impaired fasting glucose at baseline who had undergone biennial medical evaluation through the National Health Insurance Corporation from 2000 to 2004. Impaired fasting glucose was defined as fasting glucose of 100 to 125 mg/dl and the subjects were divided into 3 groups depending on weekly exercise frequency. Multivariate logistic regression analysis was used to evaluate the association between the baseline exercise status and incidence of type 2 diabetes. Results : During the 4-year follow-up, a total of 3,239 men and 283 women developed type 2 diabetes, a cumulative incidence of 16.6% for men, and 6.5% for women. Also, 1,688 men (21.2%) and 127 women (15.2%) developed type 2 diabetes in the obese group. The adjusted relative risk (RR) of developing type 2 diabetes in non-exercising men was significantly higher than exercising men regularly (RR= 1.375, 95% CI=1.236-1.529)(p<0.0001), and the RR for non-exercising women was higher than exercising women regularly (RR=1.124, 95% CI=0.711-1.778). The RR for non-exercise men/women in the obese group was 1.571 (95% CI=1.351-1.827)(p<0.0001)/1.869 (95% CI=0.846-4.130). Conclusions : Regular exercise is effective in preventing type 2 diabetes in people with impaired fasting glucose, and particularly in obese people. People with risk factors for diabetes should participate in a regular exercise program.

Objectives : With an assumption of the traditional oriental medical theory, we were to evaluate the effect of tonification/sedation-manipulated acupuncture on autonomic nervous activity in healthy subjects. Methods : This study is a randomized cross-over trial. We enrolled healthy subjects, and assigned them randomly into group A or group B. Group A received acupuncture therapy on Shen-Men (He-7) and Nei-Kuan (EH-6) with tonification-manipulation, while Group B received it with sedation-manipulation. Their heart rate variability was monitored for 2 hours. After 3 days of washout period, the subjects were crossed over to the other manipulation method, and the same procedures were performed. Results : There was no statistical significance in the change of RR, SDNN, LF, HF, and LF/HF ratio between the tonification-manipulated and the sedation-manipulated groups. However, HF curve in the tonification manipulated group showed increasing tendency for 15 minutes after acupuncture. Conclusions :We suggest that the traditional tonification-manipulated acupuncture on Shen-Men and Nei-Kuan could increase parasympathetic activity shortly after acupuncture, but further evaluation on a larger sample size is needed to confirm this suggestion.

Purpose: The purpose of this study was to investigate the relationships between LLFDI and quality of sleep in older men with prostatic hypertrophic symptoms. Methods: The secondary analysis of data collected for the 2nd stage BK(Brain Korea)21 project was performed. The original data were collected using a cross-sectional, face-to-face, and private interview method. The questionnaires consisted of prostatic hypertrophic symptoms, late-life function and disability, quality of sleep, and demographic profiles. Results: A total of 112 older men included in this study. The major findings of this study were as follow; 1) 29.5% of participants had more than moderate symptoms of prostatic hypertrophy. 2) There were a significant positive correlation of prostatic hypertrophic symptoms with subjective sleep quality, sleep latency, sleep disturbances, use of sleeping medication, and daytime dysfunction found, whereas there was a negative relationship with frequency dimension. 3) The LLFDI is significantly associated with urgency, weak stream, and intermittency. The quality of sleep is significantly associated with weak stream which explained 11.2% of variance. Conclusion: These results may contribute to a better understanding late-life function and disability, quality of sleep in older men with prostatic hypertrophic symptoms. Therefore, health programs for prompting older men's health should be planned based on results of the study.

Purpose: This study was performed to identify the meaning of life experience following suicide attempt among middle-aged men. Methods: A qualitative research design was adopted using van Manen's hermeneutic phenomenological approach. The participants were six middle-aged men who had attempted suicide at least one time. Data were collected in 2013 through in-depth interviews. Individual interviews were recorded; and literary, art works and phenomenological literature were searched to identify the meaning of the experience. Results: The five essential themes of the life experience of middle-aged men who attempted suicide were 'Bitter reality confronted again', 'Anger buried deep inside', 'Broken family, inescapable fetters', 'Blocked relationships, closed world' and 'A step towards a new life'. Conclusion: The meaning of lived experience found in this study provides deep insight into the experience following suicide attempt in middle-aged men and crucial information to give directions to appropriate support and nursing interventions.

Objectives: C-reactive protein (CRP), an inflammatory biomarker, has been widely used as a preclinical marker predictive of morbidity and mortality. Although many studies have reported a positive association between CRP and mortality, uncertainty still remains about this association in various populations, especially in rural Korea. Methods: A total of 23 233 middle-aged participants (8862 men and 14 371 women) who were free from cardiovascular disease, cancer, and acute inflammation (defined by a CRP level ${\geq}10mg/L$) were drawn from 11 rural communities in Korea between 2005 and 2011. Blood CRP concentration was analyzed as a categorical variable (low: 0.0-0.9 mg/L; intermediate: 1.0-3.0 mg/L; high: 3.1-9.9 mg/L) as well as a continuous variable. Each participant's vital status through December 2013 was confirmed by death statistics from the National Statistical Office. Cox proportional hazard models were used to assess the independent association between CRP and mortality after adjusting for other risk factors. Results: The total quantity of observed person-years was 57 975 for men and 95 146 for women, and the number of deaths was 649 among men and 367 among women. Compared to the low-CRP group, the adjusted hazard ratio for all-cause mortality of the intermediate group was 1.17 (95% confidence interval [CI], 0.98 to 1.40) for men and 1.27 (95% CI, 1.01 to 1.61) for women, and the corresponding values for the high-CRP group were 1.98 (95% CI, 1.61 to 2.42) for men and 1.41 (95% CI, 1.03 to 1.95) for women. Similar trends were found for CRP evaluated as a continuous variable and for cardiovascular mortality. Conclusions: Higher CRP concentrations were associated with higher mortality in a rural Korean population, and this association was more prominent in men than in women.

Background and Objectives: As the Korean population ages fast, it is estimated that the people with hypertension, especially female patients, will increase rapidly. However, there are few data comparing the size of female and male hypertensive patients in the Korean population. Thus we assessed sex-specific trends in the prevalence and the number of people with hypertension. Methods: We analyzed data for 128,949 adults aged ≥20 years with valid blood pressure measurements from the 1998 to 2018 Korea National Health and Nutrition Examination Survey (KNHANES). The prevalence and the absolute number of hypertension were estimated with taking into the sampling weights separately for women and men. Results: Overall prevalence of hypertension is higher in men than in women. But, in older adults, women show higher prevalence and the number of people with hypertension. Between 1998 and 2018, prevalence of hypertension increased from 61.8% to 65.9% in elderly (age 65+) women, and from 49.0% to 59.4% in elderly men. During the same period, the number of elderly women with hypertension increased from 1.18 to 2.70 million, while the number of elderly men with hypertension increased from 0.57 to 1.78 million. Among hypertensive patients, undiagnosed hypertension and diagnosed-but-untreated hypertension were more common in men, while treated-but-uncontrolled hypertension were more common in women. Conclusion: The fast-growing number of elderly women with hypertension will be an important public health challenge for the Korean society to solve in order to reduce the burden of cardiovascular disease.

Objectives : With an assumption of traditional oriental medical theory, to evaluate the effect of tonification/sedation manipulative acupuncture on blood pressure in male normotensives. Methods : This study was a randomized cross-over trial. We enrolled healthy male normotensive subjects, and assigned them randomly to group A or group B. Group A received acupuncture therapy on Shen-Men (He-7) and Nei-Kuan (EH-6) with tonification-manipulation, while group B received it with sedation-manipulation. Blood pressure was assessed every ten minutes for 2 hours. After 3 days of washout period, the subjects were crossed over to the other manipulation, and the same procedures were performed. Results : We observed that blood pressure stimulated by the sedation-manipulation had a tendency to decrease compared to that by the tonification-manipulation. Conclusions : We suggest the sedation manipulation has more synergic effect with the inhibitory effects of Shen-Men and Nei-Kuan on the sympathetic nervous system than the tonification-manipulation.

Purpose: This study aims to understand andropause symptoms and life satisfaction among middle-aged Korean men. Method: The subjects were selected among men in their middle age who visited one of two university hospitals or a convalescent center in Seoul. Korea. Eight items were used to measure their andropause symptoms. Life Satisfaction Index-Z was used to measure life satisfaction. Results: Major symptoms related andropause. in the order of frequency, include memory loss, muscle weakness. powerlessness and impotence. Among the subjects. 62.5% smoked and 70% drank alcohol. and life satisfaction was generally moderate in the participants. Current smokers and alcohol drinkers reported a low level of life satisfaction. Diabetic patients and subjects who had powerlessness and hot flashes of andropause symptoms experienced a low level of life satisfaction. Muscle weakness was more frequent in current smokers, and powerlessness more in alcohol drinkers. Conclusion: This study's findings indicate that and ropause is one of major health concerns among middle-aged men. It reminds us of the smoking and alcohol drinking issues among middle-aged men. These findings show the necessity to improve strategies for nursing intervention in andropause symptoms and health risk behaviors.
