Purpose: The purpose of this study was to investigate factors related to the levels of health-related quality of life (HRQoL) in elderly women based on Wilson and Cleary's HRQoL model. Methods: This study analyzed data from the eighth Korea National Health and Nutrition Examination Survey 2019 on 868 women over the age of 65 years. Based on the HRQoL model, parameters were categorized as personal, environmental, and physiological characteristics; symptom status; functional status; and perception of health status. The data were analyzed by quantile regression. Results: The overall level of HRQoL was 0.87. Factors related to HRQoL in the 10% quantile were higher education level, higher economic status, economic activity, more walking days, fewer diseases, lower stress, less activity limitation, and higher perceived health status. Factors related to the 25% quantile of HRQoL were more walking days, fewer diseases, less activity limitation, and higher perceived health status. Factors related to the 50% quantile were age, economic activity, more walking days, fewer disease, lower stress, less activity limitation, and higher perceived health status. Factors related to the 75% quantile of HRQoL were smoking, more walking days, fewer diseases, lower stress, less activity limitation, and higher perceived health status. Conclusion: While differing parameters were identified according to the level of HRQoL of elderly women in Korea, there were five common factors. Interventions that focus on increasing walking, mitigating diseases, stress, and activity limitations, and improving perceived health status can improve HRQoL.

This research is to propose an applicable framework for real-time health surveillance and safety monitoring at construction sites. First this study aims at finding (1) a framework for health surveillance that is likely to benefit employers and employees in the industry, (2) a valid way to identify factors or conditions with potential health concerns that can occur under particular work conditions, (3) An effective way to apply wireless/mobile sensors to construction workers using real-time/live data transmission methods, and (4) A relationship between a worker's vital signs and job site environment. Biosensors for physiological response and devices for weather/work related data are to collect real-time data. Relationships between jobs and physiological responses are analyzed and factors that touched particularly contributing to certain responses are identified. When data are incorporated with tasks, factors affecting tasks can be identified to estimate the magnitude of the factors. By comparing work and normal responses possible precautionary actions can be considered. In addition, the study would be lead to improving (1) trade-specific dynamic work schedules for workers which would be based on various factors affecting worker health level and (2) reevaluating worker productivity with health status and work schedule, thereby seeking ways to maximize worker productivity. Through a study, the paper presents expected benefits of implementing health monitoring.

Since 1970, herbicides have been widely used in the crop production, especially in paddy field in Korea. In 1978, both preemergence and postemergence type herbicides are applied in the approximately 70% of total paddy field and 15% of upland to control weeds. Most herbicides control annual weeds effectively, but perennials have been problems in the paddy field. Under upland conditions, effectiveness of herbicides varies depending on many environmental conditions (soil moisture, soil physical properties, temperature, etc.) as well as uniform application of appropriate amounts of herbicides. In Korea, many research works have been concentrated on the screening of new herbicides in terms of herbicide effectiveness and yield or phytotoxicity of crops, and especially on the paddy field. However, physiological aspects of herbicidal action in plant and interaction of herbicides with the environments have not been studied approximately. Therefore, researches on the uptake of herbicides and the influence of herbicides on the physiological phenomena such as photosynthesis, respiration, nutrient uptake etc., to control troublesome perennial weeds in the paddy field are needed in future. Also some researches are needed to improve effectiveness of herbicirdes under upland conditions.

Autophagy is an intracellular degradation system that breaks down damaged organelles or damaged proteins using intracellular lysosomes. Recent studies have also revealed that various forms of selective autophagy play specific physiological roles under different cellular conditions. Lipid droplets, which are mainly found in adipocytes and hepatocytes, are dynamic organelles that store triglycerides and are critical to health. Lipophagy is a type of selective autophagy that targets lipid droplets and is an essential mechanism for maintaining homeostasis of lipid droplets. However, while processes that regulate lipid droplets such as lipolysis and lipogenesis are relatively well known, the major factors that control lipophagy remain largely unknown. This review introduces the underlying mechanism by which lipophagy is induced and regulated, and the current findings on the major roles of lipophagy in physiological and pathological status. These studies will provide basic insights into the function of lipophagy and may be useful for the development of new therapies for lipophagy dysfunction-related diseases.

Osteocalcin (OC), a marker of bone turnover, displays patterns in relation to physiological and genetic factors. Here, we present an association study in a population of Chinese Holstein cattle (n = 24) with OC serum concentration as a phenotypic trait. We hypothesised that OC status is associated with phylogeny, vitamin D serum level and single nucleotide polymorphisms (SNPs). Mitochondrial DNA (mtDNA) was used as an unlinked marker to examine phylogeny and linkage to measured phenotypic traits of vitamin D and OC status. Following an association study with OC serum variability as the trait, genotyping of SNPs (n = 27) in OC-related genes was performed. Candidate SNPs were chosen in genes with an emphasis on the vitamin D and vitamin K pathways. Multivariant factor analysis revealed a correlation between vitamin D serum concentration and a SNP in the gene GC (rs43338565), which encodes a vitamin D-binding protein, as well as between a SNP in NFATc1 (rs42038422) and OC concentration. However, univariate analysis revealed that population structure, vitamin D serum levels and SNPs were not significant determinants of OC status in the studied group.

Purpose: The purpose of this study was to identify the factors that influence the functional status of patients with heart failure. Method: A descriptive, correlational study design was used. The participants in this study were 260 patients with heart failure who were admitted at Y University and U University in Seoul, Korea. Between September 2005 and December 2005 data was collected by an interview using a questionnaire and from medical records. The Functional status was measured with KASI. Physical factors (dyspnea, ankle edema, chest pain, fatigue, and sleep dysfunction), psychological factors (anxiety and depression), and situational factors (self-management compliance and family support) were examined. Result: In general, the functional status, anxiety, depression, self-management compliance, and family support was relatively not good. The level of fatigue was highest and the level of ankle edema was lowest for physical symptom experiences. In regression analysis, functional status was significantly influenced by dyspnea(23%), age(13%), monthly income(7%), fatigue(3%), ankle edema(2%), depression(1%), and length of stay in the hospital(1%). These factors explained 50% of the variables in the functional status. Conclusion: These results suggest that psycho-physiological symptoms management should be a focus to improve the functional status in patients with heart failure.

Purpose: This research was designed as a pre-post experimental study with a nonequivalent control group to verify the effects of meridian exercise on health status, depression and self-esteem in institutionalized elderly people. Method: The research population included 38 participants, 65 years and over, who were assigned to an experimental group (18) or a control group (20). All of the participants were institutionalized in Seoul Data collection was done from October. 2000 to May, 2001 and the experimental treatment for this study, meridian exercise, was done for a total 30 minutes per session for 12 sessions over two weeks. The exercise was developed by a professor of Oriental Medicine and the researchers involved in this study. The data were analyzed using the SPSS PC+ program. Result: There were no significant differences for general characteristics between the two groups. Physical health status, mental-mood health status, depression and self-esteem were low. Differences in the physical health status of the elderly people was higher in the experimental group (t=16.299, p=.000). The effects of the meridian exercise on mental-mood health status, depression, and self-esteem were statistically significant (t= 10.301, p= .000 ; t=15.579, p=.000, t=14.571, p=.000). Conclusion: According to the results, meridian exercise should be used to improve health status, reduce depression and increase self-esteem, and so promote the quality of life for elderly People who must be institutionalized. A study to measure the physiological index in meridian exercise for elderly people is suggested as a method to set up a Korean nursing intervention to enable elderly people to manage their own health.

The purpose of this study is to identify the effects of lifestyle, study stress and training stress on health status, and provide fundamental data for health management of university students majoring in physical education. In this study, 149 students participated and they were surveyed demographic characteristics, lifestyle, Maslach burnout inventory (student stress inventory), training stress inventory, and Mibyeong index. Height and weight were measured for calculating BMI. For statistical analysis, Student t-test, ANOVA test, chi-square test, correlation analysis, and multinominal logistic regression test has been used. There were differences between Mibyeong groups according to digestion status, smoking for female students and quality of sleeping for both male and female students. Study stress and training stress also affected to health status. Cynicism among study stress categories and all categories among training stress showed differences between sex. Correlation analysis and logistics regression analysis was used to estimate related factors of health status after adjusting for sex and age. Based on logistics regression analysis, quality of sleeping affected to Mibyeong 1 group and quality of sleeping, smoking and digestion status affected to Mibyeong 2 group. Among training stress category, dissatisfaction with game result and skills and lack of leisure time were affected to both Mibyeong 1 and 2 group. This study suggests that lifestyle, study stress and training stress might be significantly associated with university students majoring in physical education. Through managing those influence factors, health status of students could be improved.

Objectives: The purpose of this study was to find out the fear of dentist care, subjective recognition of dental health, and quality of life in the male high school students and to analyze the influencing factors on dental health care. Methods: A self-reported questionnaire was filled out by 243 special high-school in Deagu province from March 3 to March 14, 2014. The questionnaire consisted of general characteristics of the subjects(5 questions), subjective recognition of health and activities to improve health(6 questions), dental fear(20 questions), oral health related quality of life(16 questions). The instrument for dental fear was adapted from measured by Berggren Dental Fear Survey(DFS). A total of 20 DFS questions included treatment avoidance(8 questions), stimulus reaction(6 questions), and physiological reaction(5 questions) and score by Likert 5 scale. Cronbach alpha was 0.974 in the study. Oral health related quality of life was measured by 16 questions of CPQ11-14 for the adolescents by Lau. CPQ11-14 consisted of oral symptoms(4 questions), functional restriction(4 questions), and emotional wellbeing(4 questions). The instrument was score by Likert 5 scale and Cronbach alpha was 0.9354 in the study. Data were analyzed using SPSS 18.0 program for ANOVA and multiple regression analysis. Results: Fear of dentist care showed significant differences in treatment avoidance factor(p<0.001), stimulus reaction factor (p<0.05), and physiological reaction factor(p<0.001). The factors depended on subjective recognition of health and health-improving activities and differences in treatment avoidance factor(p<0.05) and physiological reaction factor(p<0.01). The dental symptoms factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001), alcohol drinking status(p<0.001) and regular meal(p<0.001). While function limit factors showed differences in health recognition (p<0.001), interest in health(p<0.001), smoking(p<0.001), alcohol drinking(p<0.001) and regular meal(p<0.001). Mental and social stabilities factors showed significant differences in health recognition(p<0.001), interest in health(p<0.001) and alcohol drinking status(p<0.001). Among the factors influencing on the quality of life in dental health, interest in health(p<0.005), alcohol drinking(p<0.005) and physiological reaction in the midst of fear of dentist care(p<0.001) were the significant impact factor. Conclusions: It is necessary to develop a continuous and systematical program of dental health and dental care by experts so that the students can reduce the fear of dentist care by regular dental checkup and preventive treatment and care.
