Multiple symmetrical lipomatosis (MSL), also called Madelung's disease, is a rare disorder of unknown etiology and characterized by abnormal accumulation of large subcutaneous fatty masses in neck, shoulder, and upper trunk. MSL has known to predominantly affect middle-aged men with a history of alcoholism. Although the clinical course of MSL is considered to be slowly progressive, in advanced stage, fatty masses in the neck may compress the upper aerodigestive tract, resulting in dyspnea and dysphagia. The treatment of MSL is surgical resection, but radical excision is very difficult and recurrence after surgery is frequent. We report the case of 55-year-old man with long lasting MSL, which caused severe airway obstruction. This patient was admitted with progressive dyspnea and massive accumulation of fat around the vocal cord that was detected on a neck CT scan. This abnormal fatty infiltration in supraglottic region caused upper airway obstruction.
Objectives: Much attention has been paid to sleep apnea syndrome (SAS) in the elderly because of its high prevalence. It is expected that SAS in the elderly has both similarities and differences compared to SAS in the young or middle-aged populations. The aim of this study was to elucidate the characteristics and consequences of SAS in the elderly. Methods: In this study we included 210 young or middle-aged adults between 23 and 59 years (20 women and 190 men) and 65 older adults between 60 and 83 years of age (16 women and 49 men). Respiratory disturbance indices (RDIs) of the study subjects were more than 5 in an overnight polysomnography. They completed the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). Informations about body mass index (BMI), neck, waist, and hip measurements, and blood pressure were obtained. Results: No difference was observed between older adults with SAS (older SAS) and adults aged under 60 with SAS (SAS aged under 60) in RDI, apnea index, % time of oxygen saturation less than 90%, and PSQI. Obstructive apnea index and oxygen desaturation index (ODI) were lower in older SAS. Compared to SAS aged under 60, lowest oxygen saturation and central apnea index were higher in older SAS, but they were statistically not significant. BMI and neck circumference were significantly lower in older SAS compared to SAS aged under 60. Diastolic blood pressure was lower in older SAS compared to SAS aged under 60 with no difference in systolic blood pressure. Older SAS showed lower scores in ESS than SAS aged under 60. Significant correlation was observed between RDI and BMI in SAS aged under 60, but not in the case of older SAS. The relationships between RDI and neck circumference, systolic and diastolic pressure, and ESS were similar. Conclusions: The elderly with SAS were not over-weight and there was no relationship between body weight and the severity of SAS. Also, the behavioral and cardiovascular effects of SAS were not marked in the elderly, which might be partly explained by decreased ODI and relatively higher lowest oxygen saturation in older SAS. The normal aging process, aside from increased body weight, might contribute to the development of SAS in the elderly with modest complications.

Vitamin E in the body system plays an important role in preventing chronic diseases by decreasing the oxidative stress by free-radicals. However, there are not enough researches on analyzing the primary factors affecting vitamin E levels in the blood in Korean adults. Therefore, the purpose of this research was to examine blood tocopherol levels and the primary factors affecting the status. A complete lifestyle survey was performed on 314 Korean adult men and surveyed their smoking, drinking and exercising habits. The average plasma level of ${\alpha}-\;and\;{\gamma}-tocopherol$ showed similar mutual relations with plasma total cholesterol (TC), triglyceride (TG), or low density lipoprotein cholesterol (LDL-C) levels (p<0.001). Plasma ${\alpha}-tocopherol$ level of the subjects did not show any difference as smoking, drinking and exercising habits changed. However, ${\gamma}-tocopherol$ per TG showed much lower figure in smokers than non smokers (p < 0.05). Amongst diet factors, plasma ${\alpha}-tocopherol$ level showed negative correlations with Vitamin E intake, while ${\gamma}-tocopherol$ level showed positive correlations with Vitamin E intake. Erythrocyte superoxide dismutase (SOD) activity and plasma tocopherol showed negative correlations, and catalase activity and plasma ${\alpha}-tocopherol$ showed positive correlationship. The level of cell DNA damage of Iymphocyte and plasma ${\alpha}-\;or\;{\gamma}-tocopherol$ showed negative correlations. As a result of this research, the factors that affect Korean adult men's plasma ${\alpha}-tocopherol$ level are plasma TG, LDL-C and cell DNA damage in Iymphocyte, while the factors that affect ${\gamma}-tocopherol$ level are plasma TG, LDL-C and vitamin E intake based on multiple regression analysis. These findings implies that the level of different types of tocopherol depends on slightly different factors. A further research is needed on the factors involved in the differentiation of the types of tocopherol.
This study analyzed the work and retirement behavior of middle- and old-aged Koreans using panel-data based multi-state life table models. Compared to previous studies that have mainly focused on gender differences in the work and retirement behavior, this study also analyzed educational differences in the retirement life course. With respect to the heterogeneity of work and retirement experiences, this study finds that the retirement life course of men and women differs substantially. Despite their longer life spans, women are expected to have shorter working life expectancies but live in a non-working state longer, resulting in a substantially higher proportion of non-working state in their lives. In terms of educational differences, this study finds that there is little difference in the expected length of stay in the labor force across educational levels but that poorly educated persons are more likely to spend a greater proportion of their lives in the labor force due to their shorter non-working life expectancies.
Purpose: This study aimed to analyze interventions for bereaved families and evaluate their effectiveness, with the ultimate goal of supporting evidence-based nursing for bereaved families. Methods: Research trends were identified based on a search of domestic databases from January 2000 to December 2022, and a meta-analysis was conducted on interventions for bereaved families. Forty-five papers were selected, and information was extracted on participants, research design, and interventions. A meta-analysis of seven papers was performed, and the effect size was calculated. Results: Fourteen papers dealt with interventions for middle-aged women who had lost their spouses, 20 used qualitative research methods, and 20 were on art therapy programs. Thirty studies had fewer than 10 participants, and most interventions had 60~120 minutes per session and 9~16 sessions in total. There were seven randomized controlled trials, and all studies included in the quality evaluation showed a low risk of bias. Four papers measured grief as an outcome, and the effect size was -1.9577 (95% CI: -2.9206 to -0.9947), indicating that the treatment significantly decreased grief (P<0.001). Six papers measured depression as an outcome, and the effect size was -1.6775 (95% CI: -2.1835 to -1.1716), showing that the treatment significantly decreased depression (P<0.001). Conclusion: Intervention programs for bereaved families were shown to be effective in relieving grief and depression. However, programs should be developed that target middle-aged men who have lost their spouses and children who have lost their parents. Randomized controlled trials should also be conducted on interventions to reduce grief and depression.
Objectives: Elevated serum uric acid (UA) has been known to be associated with the prevalence of metabolic syndrome (MetS). However, no prospective studies have examined whether serum UA levels are actually associated with the development of MetS. We performed a prospective study to evaluate the longitudinal effects of baseline serum UA levels on the development of MetS. Methods: A MetS-free cohort of 14 906 healthy Korean men, who participated in a medical check-up program in 2005, was followed until 2010. MetS was defined according to the Joint Interim Statement of the International Diabetes Federation Task Force on Epidemiology and Prevention. Cox proportional hazards models were performed. Results: During 52 466.1 person-years of follow-up, 2428 incident cases of MetS developed between 2006 and 2010. After adjusting for multiple covariates, the hazard ratios (95% confidence intervals) for incident MetS for the second, the third, and the fourth quartile to the first quartile of serum UA levels were 1.09 (0.92-1.29), 1.22 (1.04-1.44), and 1.48 (1.26-1.73), respectively (p for trend <0.001). These associations were also significant in the clinically relevant subgroup analyses. Conclusions: Elevated serum UA levels were independently associated with future development of MetS in Korean men during the 5-year follow-up period.
BACKGROUND/OBJECTIVES: This study examined the association between refined grain consumption by subtype and the incidence of hypertension from the Korean Genome and Epidemiology Study data. SUBJECTS/METHODS: In total, 5,018 participants (2,439 men and 2,579 women) from 40 to 69 years without hypertension were recruited at the beginning (2001-2002). Blood pressure and antihypertensive medication use were assessed biennially for the incidence of hypertension during the 8-year follow-up period (2009-2010). Hypertension was diagnosed as systolic blood pressure ${\geq}140mmHg$ or diastolic blood pressure ${\geq}90mmHg$ or antihypertensive medication use. Dietary intake including refined grains was assessed by a food frequency questionnaire at baseline and the follow-up (2005-2006). A multivariate Cox proportional hazard model was used to examine hazard ratios (HRs) and 95% confidence intervals (CIs) for incident hypertension according to refined-grain consumption. RESULTS: A total of 1,377 cases of hypertension (710 men and 667 women) were newly ascertained. Frequent noodle consumers (${\geq}5servings/week$) among the women had a 2.3-fold higher risk of hypertension than infrequent noodle consumers after adjustment for potential confounders (HR = 2.31, 95% CI = 1.33-4.01, P for trend = 0.0001). However, no significant association was found among the men. The intake of other refined grain products such as white rice and breads was not associated with the incidence of hypertension. CONCLUSION: Frequent noodle consumption was positively associated with a risk of incident hypertension in South Korean women.
Objectives: Previous studies have shown that participation in social activities (SA) can prevent cognitive decline (CD) and that living arrangements (LA) can affect cognitive function. This study aimed to evaluate the effects of SA and LA on CD, as well as their interactions, using longitudinal data. Methods: Data were used from the 2006-2018 Korean Longitudinal Study for Aging, which followed 10 254 adults older than 45 years over a 12-year period. CD was defined as a ≥4-point score decrease in the Mini-Mental Status Exam over 2 years. We developed an extended Cox proportional hazards model for time-dependent covariates to estimate the hazard ratio (HR) of CD in 4 groups: (1) socially active and living with others, (2) socially active and living alone, (3) socially inactive and living with others (SILO), and (4) socially inactive and living alone (SILA). The model was stratified by gender and adjusted for important confounders. Results: The HR of CD was significantly higher in the SILO group in men (HR,1.36; 95% confidence interval [CI], 1.08 to 1.78) and in the SILA group in women (HR, 1.72; 95% CI, 1.08 to 2.75). However, the interaction term for gender was not significant. Conclusions: Among socially inactive elderly adults, the HR of CD was elevated in men who lived with others and in women who lived alone, although the interaction term for gender was not significant. Socially inactive men who live with others and socially inactive women who live alone are particularly encouraged to participate in SA to prevent CD.
It is a general trend in the world that female workers are drastically increasing due to the facts that highly developed capitalism requires women's job, women are inspired to work, housewives can shorten their working hours for house-keeping and save their energy from their routine works, educational expenses of their children become larger, large among of modities has stimulated purchasing desire. Since the International Treaty on Prohibition of Female's Night Labor was agreed at the Bern's Conference in 1906, the International Labor Organization (I.L.O.) established after the World War II, has adopted innumerable international labor treaties. According to the laws of the advanced countries, the first priority of their protection has been placed on juvenile and female workers. The legal protection of female workers and equal treatments such as wage and promotion between men and women have become important world problems. In this thesis, the great principle of the Labor Standard Law, protection regarding working house, risk and harm in performance of jobs, protection of mother-workers, protection of women workers in advanced countries and the present status of welfare facilities for women workers in our country will be studied. The most important points this thesis has placed stress and appealed, are as follows : 1. The scope and variety of women workers' jobs should be broadened. 2. Opportunity for promotion should be guaranteed for women workers based upon the ability and capacity of individual woman worker. 3. Equal wage principle between men and women workers, should be established based upon the idea that men and women should be equal. 4. The age limit or marriage limit of employment applied only to female workers, should be abrogated. 5. The ability of middle and old aged women workers should be developed and utilized to the maximum extent. 6. Welfare facilities for women workers, should be urgently secured and guaranteed.

The purpose of this study was to Investigate men's clothing in regard to (1) the effect of wearer's age and clothing: rues on impression formation, and (2) the effect of perceiver's age on impressions formed by the wearer's age and the fuction of clothing cues. The experimental design of this study was between-subjects 24_full factorial design by 4 independent variables. The subjects consisted of 192 subjects in each of two male perceiver groups according to age(20s and 50s). The experimental moterials developed for the study were a set of stimuli al)d a response scale. The stimuli consisted of 16 color photographs made by identical manipulations of 4 independent variables consisting of 2 levels each. Each one of the sixteen sub-samples included 12 subjects from 2 perceiver groups. The independent variables provided by the photographs were (1) wearer's age (20s and 50s), (2) suit color (navy blue and beige),' (3) suit style (single breasted and double breasted), and (4) necktie color (analogous and complementary colors) . The 7-point semantic differential response scale which was designed to measure the impression of the stimuli was composed of 30 bipolar adjectives. The responses to the semantic differential scales were analyzed using factor analysis and ANOVA. The results were as follows:1) Wearer's age, suit color, suit style, and necktie color had significant effects on impression of the 3 factors (appearance·potency, individuality activity, and evaluation) partiafly. However, the suit style was the most dominent clothing cue : the single breasted suit conveyed positive impression of individuality' activity to both of the wearer's age groups than double breasted suit did on both of the perceiver's age groups. 2) Perceiver's age partially influenced impressions formed by the age and the clothing cues of men clothed in suits : the young perceiver's group was less affected by them than middle aged group.
