There have been continuous improvements in human life expectancy. Life expectancy is as a key factor in an aging population and can wreak severe damage on the financial integrity of pension providers. Hence, the projection of the accurate future mortality is a critical point to prevent possible losses to pension providers. However, improvements in future mortality would be overestimated by a typical mortality projection method using the Lee-Carter model since it underestimates the mortality index ${\kappa}_t$. This paper suggests a mortality projection based on the projection of the skewness of the mortality versus the typical mortality projection of the Lee-Carter model based on the projection of the mortality index, ${\kappa}_t$. The paper shows how to indirectly estimate future t trend with the skewness of the mortality and compares the results under each estimation method of the mortality index, ${\kappa}_t$. The analysis of the results shows that mortality projection based on the skewness presents less improved mortality at an elderly ages than the original projection.
Fermented milks have been recognized as healthy foods since ancient times, but those using intestinal bacteria such as Bifidobacterium and lactic acid bacteria (LAB) are even more valuable from the standpoint of view of maintaining health. They have also now come to be recognized as important in the field of preventive medicine. Although advances in the medical sciences in the last 50 years have significantly increased the human lift span, an unfortunate fact is that many of us are now living long enough to experience chronic disorders such as coronary heart disease, hypertension, osteoporosis, diabetes and cancer. In recent years there has been renewed interest in health promotion and disease prevention by incorporating probiotic bacteria into foods to counteract harmful bacteria in the intestinal tract. Therefore, there are now a wide variety of commercial products containing prospective probiotics that claim health-promoting effects, such reductions in large botvel carcinogens and mutagens, antitumor properties, cholesterol-lowering effects, increased lactose digestion, relief from con-stipation, stimulation of immunocomponent cells and enhancement of phagocytosis. Two well-known representative probiotic is LAB and Bifidobaclerium. Traditional probiotic dairy strains of LAB which have been designated as GRAS (Generally Recognized As Safe) bacteria have a long history of safe use and most strains are considered comestible microorganisms with no pathogenic potential. Accordingly, there is considerable interest in extending the range of foods containing probiotic organisms from dairy foods to infant formulas, baby foods, and pharmaceuticals. In addition, the ingestion of probiotics, prebiotics, and symbiotic as wll as combinations of pro- and prebiotics has recently aroused renewed interest as enhancing the beneficial relationship between the host and intestinal microflora in both healthy and diseased indivisuals. Non-communicable chronic diseases such as cancer, cerebral hemorrhage, is chemic heart disease, and diabetes mellitus has recently been recognized as adult diseases in Japan as well as other countries. and are considered to be inevitably associated with aging. These diseases occur as a result of individual life styles. The Japanes Government. Ministry of Health, Labor and Welfare has proposed substituting the term 'adult diseases' with 'lifestyle-related diseases'. It has emphasized the importance of prevention rather than treatment. since the well-known increase in the elderly population in Japan is predicted to result in a variety of socioeconomic problems. n this lecture on the Present status of fermented milk products in Japan, I will report a strategy for the development of fermented milk products in Japan from the standpoint of view of research in Japan on LAB and Bifidobacteria. They could play an important role in preserving human health by controlling intestinal microflora capable of producing toxic effects on the host.
Background: Lung cancer and chronic obstructive lung disease often coexist in the same person who are elderly and cigarette smoking. There are several reports that the presence of chronic obstructive pulmonary disease constitutes an independent risk factor for the development of lung cancer. Moreover, the association between mucus hypersecrtion and lung cacer has been reported. Method: In 72 cases with primary lung cancer which were confirmed histopathologically at Chonbuk University Hospital from August 1986 to July 1991, We evaluated the relationship between spirometry and lung cancer characteristics. Results: Six cases(8.3%) showed normal lung function, 16(22.2%) cases showed pure restrictive lung disease, 46(63.9%) cases showed moderated obstructive lung disease and 4(5.6%) cases showed severe obstructive lung disease. $FEV_1$(%) was lower in central type than in peripheral type, lower in advanced non-small cell cancer and lower in subjects with phlegm. $FEV_1$/FVC(%) was higher in small cell cancer than in squamous cell cancer and higher in patients without previous pulmonary disease than with previous pulmonary disease. But there was no statistically significant difference in lung function according to histologic types and smoking history. Lung cancers with $FEV_1$/FVC less than 75% consisted of 35 cases of squamous cell cancer, 7 of small cell cancer(14%), 5 of adenocarcinoma(10%), 2 of large-cell carcinoma and 1 of unclassified carcinoma. Squamous cell carcinoma occured more in patients with $FEV_1$/FVC<75% than with $FEV_1$/FVC$\geq$75%(p<0.05). Conclusion: It was suggest that low $FEV_1$/FVC, as reflection of obstructive lung disease, may be at greater risk for squamous cell carcinoma in cigarette smoker.

Objectives : To describe the characteristics of a mumps epidemic in Cheju-do, 1998 and to identify the risk factors associated with mumps infection. Methods : To estimate attack rate, previously collected data from the Nationally Notifiable Communicable Disease Reporting System and School Health Reporting System, temporarily administered by Division of Education. as well as additional surveillance data were used. In order to identify the clinical characteristics and risk factors associated with mumps, we conducted a questionnaire survey in 17 schools (9 elementary, 4 middle, and 4 high schools) among a population that included healthy students. Results : From March 3 to August 31, 2,195 cases of mumps were identified, and patients under 20 years of age accounted for 2,162 cases (attack rate 13.2, 95% CI 12.6-13.7/1,000). The attack rate for the population under 20 years of age was the highest in Nam county (44.7/1,000), nod in the 7-12 years old sub-group(>20.0/1,000). There was no sexual difference. 80.5% and 59.7% of patients presented periauricular and submandibular swelling respectively. Aseptic meningitis was a complication in 2.9% of cases, orchitis in 1.3%, epididymitis in 0.9% and oophoritis in 0.6% respectively. The overall MMR vaccination rate was 59.1% and it decreased in accordance with increasing age. In students aged 10 years old or below, household contact and MMR vaccination status was significantly associated with infection, and only among students with household contact, the risk of one dose MMR(OR=10.22, 95% CI 2.92-35.78) and non-vaccination (OR=11.62, 95% CI 1.96-68.96) was significantly greater when. compared with that of two dose vaccination. Among students aged 11 years old or above, household contact history was significantly associated and MMR vaccination status was not associated. Conclusions : Low vaccination rate and vaccine failure were thought to predispose the population for this large outbreak. To prevent sustained mumps outbreaks, a second MMR vaccination should be encouraged and catch up vaccinations should be given to elderly children who remain susceptible.
Background: The aim of the study was to describe the characteristics, treatments, and outcomes of critically ill patients with pandemic Influenza A/H1N1 2009 at a major medical center in Korea. Methods: This retrospective observational study examined critically ill adult patients with pandemic Influenza A/H1N1 2009, who were admitted to the AMC between August and December 2009. Results: 27 patients with confirmed pandemic Influenza A/H1N1 2009 were admitted to the intensive care unit (ICU) at the Asan Medical Center (AMC). The median age (IQR) was 59 years (41~67), and 66.7% of the patients were older than 51 years. A total of 81.5% of the patients had 2 or more co-morbidities. The median time (IQR) from symptom onset to presentation was 2 days (1~4), and the median time from presentation to ICU admission was 0 days (0~1.5). All patients received oseltamivir (300 mg/day) and 13 patients received triple combination therapy (oseltamivir, amantadine, ribavirin). Twelve patients required mechanical ventilation on the first day of ICU admission. A total of 6 patients (22.2%) died within 28 days of admission. The patients who died had significantly higher acute physiology and chronic health evaluation (APACHE) II and sequential organ failure assessment (SOFA) scores at presentation. There were no significant differences in age, co-morbidities, or antiviral regimens between survivors and non-survivors. Conclusion: Critical illness related to pandemic Influenza A/H1N1 2009 was common in elderly patients with chronic co-morbidities. All patients were given high-dose oseltamivir or triple combination antiviral therapy. Nonetheless, patients with critical illnesses associated with pandemic Influenza A/H1N1 2009 had a death rate of 22.2%.
In this study, using the raw data of the 7th Food Consumption Behavior Survey(2019), compare and analyze what factors affect the food delivery service and take-out food expenditure of single-person and multi-person households. It was found that women(especially women in single-person households), have a high tendency to pursue safety preference versus price. In the future, Korea's population structure is expected to steadily increase single-person household and elderly households, and women's participation in economic activities is expected to continue to increase. In addition, the food delivery market has more than doubled compared to the previous year in 12 cities and provinces out of 17 cities and provinces nationwide with Covid-19, especially in the non-capital area, making it has become a universal service nationwide. Therefore, the growing home meal replacement market needs marketing strategies to secure and emphasize food safety.

Transcranial doppler is a non-invasive method that measures the blood flow velocity and the direction of cerebral blood vessels through the doppler principle. The pulsatility index is an index for measuring the transcranial doppler that reflects the distal vascular resistance and is used as an index for the presence and diffusion of cerebral small vessel diseases. The purpose of this study was to evaluate the risk factors affecting the basilar artery pulsatility index in ischemic stroke patients. From January 2014 to May 2015, 422 patients were selected by measuring the transcranial doppler pulsatility index, considering their basilar artery pulsatility index. Univariate analysis was performed using the basilar artery pulsatility index as a dependent variable. Multiple regression analysis was performed considering the factors affecting the pulsatility index as variables. Univariate analysis revealed age, presence of hypertension, presence of diabetes mellitus, presence of hyperlipidemia, and hematocrit (P<0.1) as factors. Multiple regression analysis showed statistically significant results with age (P<0.001), presence of diabetes (P=0.004), and presence of hyperlipidemia (P=0.041). The risk factors affecting the basilar artery pulsatility index of transcranial doppler were age, diabetes, and hyperlipidemia. Further research will be needed to increase the cerebral pulsatility index as a surrogate marker of the elderly, diabetes, and hyperlipidemia.

This study was conducted as basic research for establishing a mid to long term development plan for libraries in Uiseong-gun, designated as a depopulated area. First, the social, cultural, and environmental characteristics of Uiseong-gun were analyzed and compared with the library infrastructure of depopulation areas similar in size with Uiseong-gun. In addition, a survey was conducted on the perception of users to understand the usage status of libraries, satisfaction with services and improvement plans, non-use factors, and demands for new libraries. Based on this process, the direction of Uiseong-gun library policy was presented. Specifically, four strategic directions for the development of libraries (future orientation, community revitalization, service specialization of the information poor, enhancement of local humanities and spiritual culture) and five key service tasks (building library brand, implementing innovative spaces and services, expanding library functions for improvement of settlement conditions of residents, developing and providing services for the elderly reflecting local characteristics, promoting reading culture) were derived. The proposed core tasks focused on future-oriented library services to overcome the limitations of a population decrease area and develop the potential of Uiseong-gun.
The various types of improper usages in the process of delivering social services have been increasingly paid to attention in South Korea. This study, relying on empirical data about the various improper behaviors, explore whether the audit activity can reduce the degree of the improper behavior. In order to estimate the impact of the audit, we use the DID(Difference in difference) method, comparing the experimental group with the audit treatment and the control group without it. We control for size(the number of Service personnel and user), types of social service (elderly, disabled, etc.), organizational forms(profit, non-profit), region(metropolitan areas, small-medium cities, rural areas), and the number times of audit (1, 2, and 3 number). Our empirical results show that the audit decreased the ratio of payment violation by about 4.02 percent, the number of violations from providers' improper payment by approximately 5.07 and the number of violations from users' improper payment by approximately 9.59. Further research is required to explore why and how the audit can decrease the improper usage in social service with rigorous theoretical models.
The purpose of this study was to examine the mediating effect of self-esteem in the effect of nursing caregivers' job enthusiasm on job satisfaction. For research analysis, 160 nursing caregivers' engaged in 2 institutions located in Gyeonggi-do, 3 institutions located in Seoul, 5 institutions located in Chungcheongnam-do, and 9 institutions located in Chungcheongbuk-do were surveyed from April 1 to September 2022. Data were collected non-face-to-face using Google links until the 30th. From the collected data of 140 people, 118 copies were used for the final analysis, excluding 22 incomplete responses. First, the effect of positive(+) effect on self-esteem of nursing care workers was confirmed. Second, it was confirmed that caregivers' job enthusiasm had a positive(+) effect on job satisfaction. Third, in the effect of caregiver's job enthusiasm on job satisfaction, it was confirmed as a partial mediating effect of self-esteem. In addition, the Sobel Test was conducted to confirm the significance of the mediating effect, and the significance of the mediating effect was also confirmed. This study has significance in that it suggests social welfare practices and policy interventions necessary to increase job enthusiasm and self-esteem for job satisfaction of nursing care workers, who are the main agents of caring for the elderly.
