This study aims to enhance the life satisfaction of the elderly population in South Korea by exploring their satisfaction levels and identifying influencing factors. Utilizing data from the 17th Korean Welfare Panel, which includes 6,260 individuals aged 65 and older, this study employs independent sample t-tests, one-way ANOVA, and hierarchical regression analysis. The results showed that, in general, the life satisfaction of the elderly population was somewhat lower than that of the general adult population in all areas, except for job satisfaction and satisfaction with housing. Key factors influencing life satisfaction among the elderly population include demographic characteristics (gender, age, economic activity, residence, education level), subjective health status factors, financial factors (disposable income, monthly living expenses), and psychological factors (depression, self-esteem). Notably, psychological factors, particularly self-esteem and depression, profoundly affect all life satisfaction domains. Enhancing life satisfaction necessitates fostering positive self-perception and capabilities in the elderly population, suggesting the need for programs focused on positive emotional experiences. Moreover, depression significantly reduces life satisfaction, underscoring the importance of policy interventions to address negative emotions in this demographic. This study is expected to provide basic data for establishing concrete and effective policies for improving the quality of life for the elderly population. Additionally, by highlighting the importance of positive psychological factors, it is anticipated that the study will offer a new direction for improving the life satisfaction of the elderly population.

Objectives : The purpose of this study was to develop outcome indicators in clinical trials of herbal drugs effective for asthma. cough and sputum. To accomplish the objective, this study collected outcome indicators developed and used according to conventional medical concepts. Methods : Our research group reviewed SCI papers concerned with developing outcome indicators to evaluate amelioration of asthma, cough and sputum. We also reviewed clinical trials of herbal drugs effective for them. Results : To evaluate asthma, objective as well as subjective methods were chosen according to the purpose of each trial. Objective methods were PEF, FEVl, serum IgE, peripheral eosinophil counts, and so on. Subjective methods were symptom scores, symptom diaries, quality of life measures, etc. To evaluate cough and sputum, objective and subjective methods were also chosen. Objective methods were tussigenic challenges, sputum induction and computerized methodology, and subjective methods were similar to the methodology evaluating asthmatic symptoms. Conclusions : It is desirable for a clinical trial evaluating herbal drugs for asthma, cough and sputum to use objective and subjective outcome indicators together. However, biological outcome indicators, a kind of objective methods, can not be chosen as the purpose of trial. Valid and reliable subjective outcome indicators are needed to develop good clinical trials of herbal drugs effective for asthma, cough and sputum.

The present study aims to investigate the sequential mediation model in the relationships between optimistic bias, subjective perception, risk perception, and the future time perspective in terms of a particulate matter and depression, using the sequential mediation model. An online self-reported survey was conducted on 545 participants who agreed to participate in the current study. We considered depression as a dependent variable, optimistic bias as an independent variable, and subjective perception of particulate matter, the risk perception of particulate matter, future-time-perspective as mediators. The sequential mediation analysis was conducted using the SPSS Macro. The results show that optimistic bias was not directly related to depression, but was related to indirect paths through the subjective perception of particulate matter, the risk perception of particulate matter, and future time perspective. More specifically, the lack of optimistic bias was related to a tendency to subjectively perceive the quality of air pollution more seriously and a limited future time perspective, which subsequently related to depression. Future studies should pay more attention to the effects of particulate matter on the quality of life and mental health.

The purpose of this study was to promote an understanding of suicidal ideation and identify the factors that influence suicide ideation according to the life cycle of Korean adults. This study was a secondary analysis study using the Korea Health Panel 2016 data. Among adults over 19 years of age, 14,538 people with no missing values in suicidal ideation and influencing factors were classified into young adults (19-39 years old), middle-aged adults (40-64 years old), and the elderly (65 years or over). The data were analyzed by multiple logistic regression. The results showed that 2.9% (108 people) of young adults, 3.2% (181 people) of middle-aged adults, and 3.7% (80 people) of the elderly had suicide ideation over the past year. Factors influencing suicidal ideation by life cycle were anxiety, depression, drug use and quality of life for young adults, subjective health status, stress, anxiety, depression, drug use and quality of life for middle-aged adults. The factors affecting the elderly were body mass index, stress, anxiety, depression, and quality of life. Therefore, factors influencing suicidal ideation should be considered as a major factor for screening risk groups according to the life cycle, and differentiated intervention programs should be developed and provided to prevent and manage suicide in risk groups.

Objective: This study investigated the effect of Yin deficiency medicine on halitosis patients and the relationship between subjective recognition and objective symptoms of oral malodor. Methods: We administered Yin deficiency medicine, such as Jaeumganghwa-tang, and conducted the Halitosis Associated Life-quality Test (HALT) and $OralChroma^{TM}$. Subjective recognition of halitosis was evaluated using HALT. Objective symptoms of halitosis were evaluated using $OralChroma^{TM}$. In addition, before and after administering medicine, we determined the halitosis according to percentages at the patient's word. Results: The total gas and HALT were not related to each other after Maekmoondong-tang or Saengmaek-san were administered to 10 halitosis patients. Conclusion: Yin deficiency medicine is effective in treating halitosis. Moreover, the subjective recognition and objective symptoms of halitosis are not related to each other.
