This current survey was conducted to examine consumer attitudes toward factors determining beef purchasing and improving distribution systems. The frequency of beef purchasing was shown to reflect social and economic status, where inhabitants in large cities, such as Seoul, with higher salaries showed a higher frequency. In addition, consumers that were in their forties bought beef more frequently than consumers that were in their twenties. Consumers in Seoul and the megalopolis with a monthly income of higher than 200 million won preferred to purchase meat from department stores and discount markets. In contrast, people in small cities with lower incomes tended to buy meat from butcher shops and brand shops. In a question regarding unsatisfaction factors of retail beef, individuals that were in their thirties with a high income had concerns associated with packaging problems. For people under thirty with low income, the consistency of quality and price were the prime concerns. In regards to the beef grading system, consumer response varied between inhabitants, monthly income and age group, where consumers from small cities that were in their twenties and forties with a low income had a negative viewpoint. For the differential beef distribution system, housewives between the ages of 30 and 40 from a small city with an income higher than 200 million won had a positive response; however, a large number of consumers were not familiar with this system. The most demanding beef cuts were in the following order: loin, flank and rib. In addition, the most important factors determining purchasing beef were as follows: price, breed and portion.

This study examined the effects of antecedent variables on life satisfaction of elderly people who live alone and who live with others by comparing the levels of depression, self-esteem, and life satisfaction. Using the 15th data of the Korean Welfare Panel held in 2020, independent sample t-test and hierarchical regression analysis were conducted. Elderly people who live alone had a high sense of depression, low self-esteem, and low life satisfaction. For both of them, the older the age and the higher the income level, the higher the life satisfaction. The regression model, which added depression and self-esteem, had a significant effect on both of them, but the effect of self-esteem was higher (𝛽=.40, .41) than that of depression (𝛽=-.28, -.29). The effects of depression and self-esteem on life satisfaction were higher in elderly people who live alone (R²=.409) than in elderly people who live with others (R²=.398). Based on the research results, this study suggested appropriate policies and practice directions to enhance self-esteem and improve life satisfaction of elderly people who live alone.

Seomin has been used frequently in mass media and political discussion. However, who is Seomin, how to define Seomin, and whether Seomin and middle class are different has been rarely discussed. This study conducted both national level of survey and in-depth interviews and explored how to define Seomin and who respondents think as Seomin. The majority of respondents consider themselves as Seomin and that monthly income is the most important criteria to define Seomin. Seomin was considered as those who have high school education and 200~300(million won) monthly income, live in a rented house, and work as a small-scale self-employer, skilled laborer, and low level of white collar workers. Also, Seomin is a precarious group which can achieve upward or downward mobility and is located between low and middle class. Those who have Seomin identity tend to have pride in their social status and hope for upward mobility rather than depreciate their social status or envy the middle class. In order for Seomin to be able to achieve upward mobility and to maintain pride in current status, diverse social policies are needed. Further analyses on examining characteristics and policy needs of Seomin are needed.

Along with the aging society, the prevalence of dementia is also increasing. Dementia causes short-term memory loss as well as difficulties of performing daily activities and gradually causes suffering of the patients and their family. In spite of various programs for prevention of dementia of older people are being implemented, there is a lack of developing natural-based program for physical and mental health promotion. Therefore, it is necessary to develop programs for the elderly living alone who are more vulnerable to dementia because of their social and economic isolation. The purpose of this study was to develop a natural-based program and investigate the effects of 10 weeks forest therapy program for dementia prevention to improve the psychological and physical health of the elderly living alone. The experimental subjects were 30 elderly (aged 65 or older) and 31 elderly participated in control group. The Stress response, depressive symptoms, weight, body mass index (BMI), fat mass and muscle mass were measured for pre and post test. The results showed that the experimental group showed subjective stress relief (t=5.249, p=.000), improvement in symptoms of depression (t=4.152, p=.000), and decreases in weight (t=2.686, p=.012), BMI (t=2.629, p=.014) and fat mass (t=2.918, p=.007) after the forest therapy program. The experimental group showed lower stress reactions(t=-7.185, p=.000) and less depressive symptoms (t=-5.303, p=.000) than control group after participating the program. These results suggest that periodic forest exposure can help having less stressful and depressive status than non-forest exposure and the forest therapy program can reduce participants' psychological and physical risk factors of dementia.

Since the 90's, Korean Air transport market has been more expanded because of economic growth, the construction of airport infrastructure, and the advent of low cost carrier. Especially, the air traffic demand in Busan metropolitan area has been increasing steadily. Therefore, in this paper, we developed a new forecasting model which could expect the future air traffic demand in Busan area. This model is developed by regression analysis using social-economic variables such as GRDP, income, and the number of people, and dummy variables, for instance, KTX opening, Japan economic depression, SARS and so on. Result from demand forecasting by this new model suggests that the new airport system is needed in order to sustain the increasing air traffic demand in Busan area.

The objective of his study is to research the effect of the 'Dagagu' housing purchase and the public rental housing supply on the nearby community. In the case of public rental housing, many studies have demonstrated that the perception that a public rental house is a low income dwelling has an external effect on the residents immediately outside the area such as the perception of the lowering of house prices. However, an advanced research concerning the 'Dagagu' housing purchase and public rental housing has not been carried out because it has only recently been enforced. Through a survey conduced of residents who live nearby the 'Dagagu' housing purchase and public rental housing the aim of his study is to show how the residents perceive the renal houses and are influenced by them. At the same time, this study demonstrates the external effect of rental house supply by analyzing the housing price around the area. Most people who live in the near by 'Dagagu' housing purchase and public renal housing have a negative opinion of his housing because they believe that the residential prices will depreciate. However, only about 40% of the people felt that the residential price depreciation as a result of the 'Dagagu' housing purchase and public rental housing supply was not visible.

In 2015, the population of elderly people in Thailand was 16% of the total population and is predicted to be over 20% by 2021 and nearly 28% by 2031. The increase of the elderly population in Thailand has also increased the proportion of dependent elderly people, and caring for them poses many challenges for both families and the government. This descriptive method research aimed to survey the health status of dependent older people in the rural community of Lampang province in northern Thailand. The participants consisted of 62 older people and 62 primary family caregivers from Hong Ha Health Promoting Hospital, Lampang, Thailand (totaling 124 people). The researchers assessed the health status of older people and their activities of daily living (ADL). In addition, researchers assessed the health status and stress of caregivers. All the participants were interviewed about their experiences with caregiving. The results showed that most of the older respondents were female with an average age of 78.15 years. Based on the ADL assessment, 50 of the 62 older persons were homebound while the rest were bedridden. The majority of older people had chronic or long-term conditions that required hospitalization from time to time. Their frequent health problems included oral disorders such as tooth decay or caries/gum disease/no teeth, reduced sight, psychological disorders, knee pain and risk of falling, low BMI, risk of malnutrition, and urinary leakage and incontinence (58.06%, 66.13%, 62.90%, 70.97%, 38.71%, 66.13%, and 37.10%, respectively). Usual care provided by the family members included personal hygiene care, food preparation and feeding, medication management, housekeeping and organizing necessary equipment, supply of needed equipment, prevention of falls, helping with travel for medical checkups and treatment, and providing companionship. Families experienced shortages of medical supplies, daily use equipment, lack of employment, inadequate income, and difficulty accessing health care services due to lack of transportation. Some caregivers experienced caregiving stress related to a lack of social interactions as well as routine caregiving activities. Families need different types of support in order to promote the well-being of older people and caregivers. This highlights the need for a community participation model for the care of older people in order to reflect sustainable long-term outcomes.

In this paper, a study was conducted to find main factorsto Pima Indians Diabetes based on machine learning. Diabetes is a type of metabolic disease such as insufficient secretion of insulin or inability to function normally and is characterized by a high blood glucose concentration. According to a situation report from WHO(World Health Organization), Diabetes is a chronic, metabolic disease characterized by elevated levels of blood glucose (or blood sugar), which leads over time to serious damage to the heart, blood vessels, eyes, kidneys and nerves. And also about 422 million people worldwide have diabetes, the majority living in low-and middle-income countries, and 1.6 million deaths are directly attributed to diabetes each year. Both the number of cases and the prevalence of diabetes have been steadily increasing over the past few decades. Therefore, in this study, we used Support Vector Machine (SVM), Decision Tree, and correlation analysisto discover three important factorsthat predict Pima Indians diabetes with 70% accuracy. Applying the results suggested in this paper, doctors can quickly diagnose potential Pima Indians diabetics and prevent Pima Indians diabetes.

The purpose of this study was to understand characteristics of groups vulnerable to extreme heat and to reduce mortality caused by high temperature. For this purpose, relationship between socioeconomic factors and mortality-threshold temperatures were studied. The study area was limited to Seoul (South Korea) and climate data from 2000 to 2010 was used. Our results indicate that mortality-threshold temperatures for regions with a high proportion of aging population and a low proportion of aging population are $27.6^{\circ}C$ and $27.9^{\circ}C$, respectively. It was also found that a relative size of welfare dependant population did not affect mortality-threshold temperatures. However, regions with a high proportion of aging and welfare dependant population experienced $0.7^{\circ}C$ lower mortality-threshold temperature than other regions. This implies that low income and older people in Seoul are more easily affected by high temperature. Thus, this study suggests that it needs a policy targeted to low income and aging population to decrease mortality rate caused by extreme heat.

Purpose: The aim of this study was to determine the scope of knowledge, attitudes, and behaviors of pregnant women about the coronavirus disease 2019 (COVID-19) vaccine. Materials and Methods: A total of 886 pregnant women were recruited for the study. A cross-sectional questionnaire was conducted on these selected participants. Data about past infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), SARS-CoV-2 infection of closely related people, and deaths due to COVID-19 among their relatives were questioned. Results: The rate of vaccination was higher (64.1%) in pregnant women with higher education levels. Informing about the vaccine, especially by health professionals, showed that the rates of vaccination (25%) increased (p<0.001). In addition, a significant increase was observed in vaccination rates with increasing age and financial income (p<0.001). Conclusion: The main limitation of our study is that the vaccine, which was approved for "emergency use", was just started to be administered to pregnant women during the study. Our findings show that our target audience, low-income, low-education, younger pregnant women should be given more attention than those who apply to the doctor for routine follow-up.
