Purpose: The purpose of this study was to explore unmet healthcare needs among low-income overweight and obese women and to identify the factors affecting unmet healthcare needs. Methods: The study was a secondary analysis of data from the 2017 Korea National Health and Nutrition Examination Survey. A final sample of 388 out of 8,127 participants was analyzed using complex descriptive statistics, the chi-square test, the independent t-test, and logistic regression. Results: The mean age of the participants was 66.51±1.05 years. Unmet healthcare needs were experienced by 19.4% of low-income overweight and obese women. Women with depression, stress, and poor self-reported health status were significantly more likely than their counterparts to experience unmet healthcare needs. Poor self-reported health status was confirmed to be related to unmet health needs in low-income overweight and obese women (odds ratio, 2.65; p=.011). Conclusion: The study provides the novel insight that the unmet healthcare needs of low-income overweight and obese women were influenced by self-reported health status. Healthcare providers should make efforts to develop strategies to reduce unmet healthcare needs among low-income overweight and obese women, who constitute a vulnerable population.
The aim of this study is to examine effects of a yoga program for children on school stress of the elementary school children. To achieve this goal, total 10 students out of 231 in 6 classes among the third graders in M elementary school in B city were selected as subjects for this study. After regular school hours, they participated in a children's yoga program for 16 times for 45 minutes per session in the course of 8 weeks. An ethnographic interview was conducted to identify the effects of the program. During the initial stage of the children's yoga program, the participants were interviewed preliminarily. An analysis of areas and an analysis of classifications were made based on the initial interview results, and an area classification table was drawn on the school stress perceived by the elementary school children. After the yoga program ended, a follow up interview was made to apply an analysis of components by comparing changes in the school stress level due to a yoga effect. A research report was written through a cycle of addition and supplement in which the previous data analysis was complemented and corrected by new findings of the study. As a result of the ethnographic interview to analyze the school stress perceived by the elementary school children, and an examination of the changes in the school stress level, the children's yoga program proved to be significantly effective in reducing the school stress. However there were limitations to a certain degree in stress reduction. Details of such findings in each sub-category are as follow. First, as a result of the initial interview analysis, the school stress was classified broadly into 4 categories of study stress, friendship stress, teacher stress, and school environment stress. Second, the study stress as the first category of the school stress was classified into 3 sub-categories of homework, class, and exam stresses. In spite of minor differences among 3 sub-categories, the stress was reduced in general. Third, the friendship stress as the second category of the school stress was also classified into 3 sub-categories of bullying, alienation, and performing one's duty. There were minor differences among sub-categories, however stress reduction also appeared with the exception of the performing one's duty category which had relatively little effect from the yoga program. Fourth, regarding the teacher stress as the third school stress, a classification was made into 3 sub-categories of preference, penalty, and teaching method. Minor differences among the 3 sub-categories notwithstanding, stress reduction appeared with the exception of the teaching method stress which had relatively little effect from the yoga program. Fifth, the school environment stress as the fourth category of the school stress was classified into 2 sub-categories of school meals and facilities. Minor differences between the 2 categories notwithstanding, stress reduction appeared with the facilities stress having relatively little effect.
This research started with the objective to clarify how policemen are affected by promotion by test among promotion system of police which is one of the very important factors deciding the efficiency of organization through morale of policemen and which is mentioned as a factor that raises morale of policeman. The job of police is the ground of life for policemen and the place of opportunity where they can find and develop the ego. Though it is difficult to perfectly realize diverse values and desires of individuals in the organizational society which is ruled by plural values, the organization is still responsible for grasping the desire and value of individual for organization and satisfying them to the minimal level. Nobody is free from stress in the past, present and future. That is, stress can be seen as a phenomenon that inevitably occurs in any occupation and environment. The stress factor of policeman in the organization that has been discussed all the time is the deficient opportunities of promotion. Thus, it is most important to manage the stress of members in the organization so as to efficiently operate police organization. If the factor of stress perceived by the members can be grasped and diminished, the efficiency of business will be increased. The objective of this research is to reduce the stress of policemen suffering in the test promotion system by analyzing the recognition of members, to find the method reducing stress by performing empirical research and to prepare alternatives in policy in the aspect of human resources in police and management of organization.

Purpose: This study examined the effects of Sargassum horneri extracts on palmitic acid (PA)-induced endoplasmic reticulum (ER) stress in HepG2 cells. Methods: HepG2 cells were treated with varying concentrations of S. horneri extract or PA, and the cell viability was measured by water soluble tetrazolium salts analysis. The effective induction of ER stress and the effects of S. horneri were investigated through an examination of the ER stress-related genes, such as activating transcription factor 4 (ATF4), X-box binding protein (XBP1s), C/EBP homologous protein (CHOP), and 78-kDa glucose-regulated protein (GRP78) by quantitative reverse transcription polymerase chain reaction. The expression and activation levels of unfolded protein response (UPR) associated proteins, such as inositol-requiring enzyme-1α (IRE1α), eukaryotic translation initiation factor 2 alpha submit (eIF2α), and CHOP were examined by western blot analysis. Results: The treatment with PA increased the expression of UPR associated genes significantly and induced ER stress in a 12-hour treatment. Subsequent treatment with S. horneri reduced mRNA expression of ATF4, GRP78, and XBP1s. In addition, the protein levels of phosphate (p)-IRE1α, p-elF2α, and CHOP were also reduced by a treatment with S. horneri. An analysis of sirtuin (SIRT) mRNA expression in the S. horneri and PA-treated HepG2 cells showed that S. horneri increased the levels of SIRT2, SIRT6, and SIRT7, which indicates a possible role in reducing the expression of ER stress-related genes. Conclusion: These data indicate that S. horneri can exert an inhibitory effect on ER stress caused by PA and highlight its potential as an agent for managing various ER stress-related diseases.

In the present study, the thermoshearing experiment on a rough rock fracture were modeled using a three-dimensional grain-based distinct element model (GBDEM). The experiment was conducted by the Korea Institute of Construction Technology to investigate the progressive shear failure of fracture under the influence of thermal stress in a critical stress state. The numerical model employs an assembly of multiple polyhedral grains and their interfaces to represent the rock sample, and calculates the coupled thermo-mechanical behavior of the grains (blocks) and the interfaces (contacts) using 3DEC, a DEM code. The primary focus was on simulating the temperature evolution, generation of thermal stress, and shear and normal displacements of the fracture. Two fracture models, namely the mated fracture model and the unmated fracture model, were constructed based on the degree of surface matedness, and their respective behaviors were compared and analyzed. By leveraging the advantage of the DEM, the contact area between the fracture surfaces was continuously monitored during the simulation, enabling an examination of its influence on shear behavior. The numerical results demonstrated distinct differences depending on the degree of the surface matedness at the initial stage. In the mated fracture model, where the surfaces were in almost full contact, the characteristic stages of peak stress and residual stress commonly observed in shear behavior of natural rock joints were reasonably replicated, despite exhibiting discrepancies with the experimental results. The analysis of contact area variation over time confirmed that our numerical model effectively simulated the abrupt normal dilation and shear slip, stress softening phenomenon, and transition to the residual state that occur during the peak stress stage. The unmated fracture model, which closely resembled the experimental specimen, showed qualitative agreement with the experimental observations, including heat transfer characteristics, the progressive shear failure process induced by heating, and the increase in thermal stress. However, there were some mismatches between the numerical and experimental results regarding the onset of fracture slip and the magnitudes of fracture stress and displacement. This research was conducted as part of DECOVALEX-2023 Task G, and we expect the numerical model to be enhanced through continued collaboration with other research teams and validated in further studies.
The purpose of this study is to identify the factors influencing the quality of life and to compare the changes in quality of life by each period group in workers with diabetes mellitus. A secondary data analysis was conducted using the data of "The Korea National Health and Nutrition Examination Survey, 2007-2015." The survey included 1141 worker with diabetes mellitus from 19 to 65. Data analysis was conducted using SPSS 23.0 program and descriptive statistics, ANOVA, and multiple regression analyses were performed. Factors influencing quality of life are gender, household income level, subject health state, restrict activity, sleeping hours, stress. Subject health state, restrict activity, stress were common factors in the 4th, 5th, and 6th period group. The difference in each group were factors influencing the quality of life, such as sleep time(4th), gender(5th), Household income level and diagnosis of angina pectoris(6th). This study can be used to convergence study the diabetic management program and social role for improving the quality of life of wrkers with diabetes Mellitus.
This study was a descriptive study to investigate factors affecting quality of life in the Korean elders with diabetes mellitus. A secondary data analysis was conducted using the data of "The Fourth Korea National Health and Nutrition Examination Survey, 2008." The survey included 9774 adults aged over 64 years with diabetes mellitus and 226 samples were used for this study. Data analysis was conducted using SPSS 12.0 program and descriptive statistics, Pearson's correlations, and multiple regression analyses were performed. Correlation analysis showed that quality of life was associated with the amount of alcohol intake, the level of stress awareness, walking time, and suicidal thoughts. The amount of alcohol intake, the level of stress awareness, walking time, and suicidal thoughts accounted for 34.5% of quality of life. These findings suggest that nursing researchers need to consider age, suicidal thoughts, and drinking as important factors affecting quality of life of Korean elders with diabetes mellitus and nursing intervention focusing on the issues needs to be developed.
Purpose: In order to provide basic information for the development of nursing programs, health promoting behavior of students rewriting college entrance examinations was examined and factors related to health promotion were identified.

Background: Breast self examination (BSE), performed regularly every month, is one of the most important methods in the early diagnosis of breast cancer. This study was performed with the aim of establishing the knowledge, attitudes, and behavior of women working in government hospitals within the province of Samsun regarding BSE. Materials and Methods: This cross-sectional study was conducted between January-March 2012, on a total of 550 women (500 health personnel, and 50 general administration services (GAS) workers) from 7 government hospitals and the Cancer Early Diagnosis, Screening, and Education Centre (CEDSEC). Percentages were used for the descriptive statistics, and the chi-square test for the evaluation of statistical importance. Values of p<0.05 were accepted as significant. Results: The mean age of the participants was $36.2{\pm}15.3$, and 42.5% were in the 30-39 year old age group, 78.0% being married. Seventy-eight point four percent (78.4%) of the health personnel and 76.0% of the GAS workers performed BSE. However, the rates of performing BSE regularly every month were only 25.6% and 5.0%. Within the health personnel, 1.4% stated that they did not perform BSE because they found it unnecessary as they had no history of breast cancer in their family, 3.6% did not do so due to fear and stress, 13.2% because they forgot, and 14.6% because they had no complaints. Some 22.2% of the health personnel and 52.0% of the GAS workers had undergone mammographic evaluation, the difference being significant (p<0.05), 84.1% of the health personnel and 61.9% of the GAS workers knowing symptoms of breast cancer. Conclusions: Women in society should be brought to a certain level of awareness and knowledge regarding BSE. It is of the utmost importance that health personnel, who carry the responsibility for counseling and enlightening society, should interiorize the necessary knowledge, attitudes and behavior.
Objectives: The purpose of this study was to investigate the smoking status and related factors among adolescents in Korea. Methods: We used data from the 5-7th Korea National Health and Nutrition Examination Survey. The distribution of smokers and smoking status according to general characteristics was analyzed using complex chi-square tests. Multiple logistic regression was used to analyze the relationship between smoking experience and general characteristics by calculating the 95% confidence intervals. Results: There were 618 subjects who had experience smoking one or two puffs, the starting age of one or two puffs on smoking was 14.37 years old, the number of smoking days per month was 12.42 days, and the amount of smoking per day in a month was 7.59. Gender, residential area, income level, drinking experience, subjective health status, perceived stress level, continuous depression for more than 2 weeks, suicidal thoughts within a year, and age were significantly related to smoking experience. Conclusions: It is necessary to understand the smoking behavior of adolescents. It is important to lower the smoking rate among adolescents through the development and operation of systematic smoking prevention and smoking cessation policies at the national level, as well as the efforts of youth themselves to quit smoking.
