This study aimed at investigating correlation of nutrients intake and serum lipids in middle-aged korean male and female workers. One hundred sixty eight(male ;105, female ;63) for adult aged 30-59yr(average age male ;36.5yr, female ;44.5yr) were selected as subjects during 2 months, from April to May, 1996. Nutrients intake status was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows: 1. Nutrients intake status ; male was superior to female. Vitamin A intakes of 40-49yr group were inferior to other group but amounts of intake were above Korean RDA(recommended dietary allowances), Intakes of calcium and vitamin C of 30-39yr and over 50yr group in female were below Korean RDA. In overweights group of male and underweight group of female, most nutrients intake were increased than other groups. 2. Antropometric assessments ; female was higher than male in BMI (body mass index). All subjects increasingly with age were increased in BMI. 3. Blood components were above normal range in triglyceride in both sexes and all subjects increasingly with age were increased In level of serum lipids and blood pressure, especially in male's forty and in female's fifty were higher than other groups In serum lipids and blood pressure. In overweights group, serum lipids and blood pressure had a significantly($\alpha$=0.05) increasing tendency in both sexes. 4. Serum lipids and connected factors; atherogenic index correlated positively with triglyceride, total-chol(total cholesterol), LDL-chol(low density-lipoprotein cholesterol) and negatively with HDL-chol(high-density-lipoprotein cholesterol) significantly(P＜0.001). Systolic blood pressure correlated positively with total-chol and diastolic blood pressure correlated positively with total-chol, LDL-chol significantly(P＜0.05). 5. Serum lipids and nutrients intake status: energy correlated positively(P＜0.05) with BMI, dietary fiber correlated positively with LDL-chol(P＜0.05), calcium correlated positively with triglyceride, atherogenic index and dietary fiber correlated negatively with BMI in male significantly(P＜0.05). Triglyceride correlated positively with vitamin C and phosphorus correlated negatively with BMI in female significantly(P＜0.05). Above results, in male's forty and in female's fifty were liable to variation in terms of serum lipids and blood pressure. As increasing triglyceride, total-chol, LDL-chol and decreasing HDL-chol Increased atherogenic index that suggest increasing risk of atherosclerosis. But, this point will be considered more subdivided study.

This study analyzed the impact of resilience on the job satisfaction of middle-aged employees and the meditating effect of retirement attitude. The survey was administered to 468 regular workers aged 40 or older in Seoul and the surrounding metropolitan area. This study utilized SPSS 19.0 statistical program, and multiple regression and mediated effect analyses were applied with descriptive statistics, reliability and validity of measurement tools to analyze differences between correlations and groups. First, male workers had higher self-regulation ability and job satisfaction than women. Female workers had higher old age rest than male ones. The higher the educational background, the higher the recognition of retirement as a new beginning, The longer the working years, the higher the self-regulation ability and job satisfaction. The higher the household income, the higher the positiveness. Second, the Resilience had a positive effect on job satisfaction. Third, resilience had had a negative impact on the forced frustration and a positive influence on the new beginning of retirement attitudes. Fourth, the forced frustration and new beginning showed mediating effects of resilience and job satisfaction. The study results confirmed the importance of resilience and demonstrated the need for measures to enhance resilience in order to reduce anxiety about retirement and increase job satisfaction.

Purpose: The purpose of this study was to examine late-onset hypogonadism, erectile dysfunction, depression, and quality of life among middle-aged male workers. Methods: The subjects included 343 men aged between 40 and 64, responded to self-report questionnaires on general characteristics, late-onset hypogonadism, erectile dysfunction, depression, and quality of life. Data were collected from May 16, 2012 to October 9, 2012 and analyzed using t-test, ANOVA, $x^2$-test, hierarchical multiple regression. Result: The prevalence rate of late-onset hypogonadism was 63.8% with high points in reduction of libido, energy, physical strength and endurance, and erectile function. There were significant differences in late-onset hypogonadism according to age($x^2$=8.98, p=.048) and in erectile dysfunction according to age(F=11.03, p<.001), monthly income(F=2.84, p=.024) and smoking( t=2.96, p=.018). Significant differences were also found in depression according to educational level(F=8.12, p<.001) and in quality of life according to monthly income(F=7.21, p<.001). The factors which influenced quality of life were late-onset hypogonadism, erectile dysfunction, depression, marital status and religion. Conclusion: Symptoms of erectile dysfunction can be improved by smoking cessation education program. In order to improve the life quality of middle-aged men, nursing intervention programs that would both provide proper knowledge on climacteric syndrome and alleviate symptoms should be designed while, at the same time, other programs to evaluate, prevent and control depression are developed.

The purpose of this study was to investigated the effects of alcohol intake on blood pressure, serum lipids, liver function tests and obesity indices in middle-aged male workers. The 2,175 male workers aged 30-59 years who examined health checkup were recruited as the study subjects during the period between January to December, 2013. We observed the relationships between the amount of alcohol intake and blood pressure, serum lipids, liver function tests and obesity indices. As a result, the mean score of SBP, DBP, LDL-C and TG were significantly higher increasing with amount of alcohol increased, but HDL-C were significantly lower increasing with amount of alcohol increased. AST, ALT, ALP and ${\gamma}$-GTP were significantly higher increasing with amount of alcohol increased, but obesity indices were not significant. Age adjusted odds ratios(ORs) increasing with abnormal levels of SBP, DBP, HDL-C, LDL-C, TG, AST and ALT were significantly increased in heavy drinking group than light drinking group. Above results suggested that the heavy drink related with blood, serum lipid levels and liver function test levels, but not find out with obesity indices.

The Purpose of this study are to examine the middle-age and old worker's employment rates by age and gender at economic depression and recovery periods after the economic crisis, to identify the main 3causes of the change of the middle-age and old worker's employment rates between two periods, and to analyze whether the determinants affecting the middle-age and old worker's employment may be different by age and gender. For this study, The Annual Korean Labor Panel data(from 1st to 7th) are used. The results show that the employment rates are increased in the economic recovery period, and the difference between male and female employment rates decrease as ages go up. As we predicted, the determinants affecting the middle-age and old worker's employment are different by age and gender. For example, the existence of partner has positive effect on the male employment, but negative effect on female employment. The increases of the middle and old age worker's employment rates in the recovery period are mainly caused by the extension of the individualism(that is, the increases of the middle and upper class workers' employment), rather than the increases of the poor workers' employment rates due to the poverty(that is, the increases of the lower and poor class workers' employment). In the recovery period, comparing to the economic depression periods, the middle-age and old workers in the high class were likely to remain his(her) a good job while those in lower class are more difficult to get a job. This results show that the polarization of middle-age and old worker's employment has been appeared in the recovery periods(after 2001).

Background: Workers are often exposed to hazardous heat due to their work environment, leading to various injuries. As a result of climate change, heat-related injuries (HRIs) are becoming more problematic. This study aims to identify critical contributing factors to the severity of occupational HRIs. Methods: This study analyzed historical injury reports from the Occupational Safety and Health Administration (OSHA). Contributing factors to the severity of HRIs were identified using text mining and model-free machine learning methods. The Multinomial Logit Model (MNL) was applied to explore the relationship between impact factors and the severity of HRIs. Results: The results indicated a higher risk of fatal HRIs among middle-aged, older, and male workers, particularly in the construction, service, manufacturing, and agriculture industries. In addition, a higher heat index, collapses, heart attacks, and fall accidents increased the severity of HRIs, while symptoms such as dehydration, dizziness, cramps, faintness, and vomiting reduced the likelihood of fatal HRIs. Conclusions: The severity of HRIs was significantly influenced by factors like workers' age, gender, industry type, heat index , symptoms, and secondary injuries. The findings underscore the need for tailored preventive strategies and training across different worker groups to mitigate HRIs risks.

Purpose: This study was conducted to identify the clinical characteristics and risk factors on the occurrence of variant angina, and to examine the predicting factors on the vascular endothelial dysfunction of the patients with variant angina. Methods: A total of 134 patients diagnosed with variant angina were recruited from 2006 to 2008. The degrees of endothelial dysfunction were measured and recorded by the researcher using the values of flow-mediated vasodilation of their brachial arteries and Nitroglycerine-mediated dilation. Subjects' demographic data and risk factors were gathered after obtaining informed consent, and their electronic medical records were reviewed to collect laboratory data. Results: The mean age was $54.2{\pm}9.6$ years and 52% was male patients. More than 50% of the male patients were cigarette smokers and had hypercholesterolemia. 84% of the male patients and 70% of the female patients had more than one risk factor of cardiovascular disease. A stepwise multiple regression analysis showed that smoking and hypercholesterolemia predicted the decrease of flow-mediated vasodilation (Adjusted $R^2$ = .204, p < .001). Conclusion: Tailored educational interventions for smoking cessation and cholesterol management are needed to prevent recurrence of angina attack for patients with variant angina and to prevent cardiovascular disease for middle-aged workers.
