Background & objectives: Cognitive function decline is a main factor influencing the overall life of the elderly and places a burden of society. The aime of this study was to investigate the risk factors of cognitive function decline of elderly living alone and living with a spouse. Methods: This study used the Korean Longitudinal Study of Ageing from 2014 to 2018. 243 older adults who lived alone and 1,155 lived with a spouse with the Korean version of Mini Mental State Examination scores in normal range at the time of 2014 were included in the analysis. Logistic regression analysis was conducted to determine the difference of risk factors affecting cognitive function decline between in elderly living alone and elderly living with a spouse. Results: Cognitive function decline incidence rate of elderly living alone was 30.5% and the elderly living with a spouse showed 23.0%. According to the results of logistic regression analysis, the risk factors of cognitive function decline in the elderly living alone was age and residential area, while in the elderly living with a spouse were age, education level, social networks, and depression. Conclusions: The factors that affect the cognitive function decline of the elderly living alone and the elderly living with a spouse were different. Accordingly, other measures to prevent cognitive decline are necessary.

Objectives: The purpose of this study was to investigate the effect of handgrip strength level on cognitive impairment in hypertensive patients. Methods: This study used the first to eighth year data of the Korean Longitudinal Study of Aging (KLoSA). Of the 10,254 respondents who participated in the basic survey, respondents were included that they were diagnosed with high blood pressure and had no cognitive impairment. The handgrip strength was based on the highest value of handgrip strength for both hands. Cognitive function using MMSE results and 23 points or less were defined as cognitive impairment. Cox models were conducted to estimate the hazard ratios (HRs) of cognitive impairment in relation to handgrip strength adjusting for covariates. Results: In the case of hypertension patients, the probability of cognitive decline decreased by 3.0% every time the maximum handgrip strength increased by 1 unit. In the analysis by age, under the age of 64 had a 1.8% decrease in the probability of cognitive decline whenever the maximum handgrip strength increased by 1 unit, and a 3.6% decrease in those over the age of 65. In the gender analysis, male had a 3.2% decrease in the probability of cognitive decline for every 1 unit increase in the maximum handgrip strength, and female had a 2.6% decrease. Conclusions: The results of this study are expected to be used as basic data for the development of interventions to prevent cognitive decline in hypertensive patients by identifying the effect of handgrip strength level on cognitive decline. It is also expected to be used as basic data for health education on the necessity of increasing muscle strength for hypertension patients in the community.

Today's universities have a keen interest in educational reform. The issue of population decline in college-age due to population decline is not new. Universities have been developing quantitatively for a long time and are now considering ways to survive rather than qualitative growth. Since the sharp decline in the school-age population due to the population decline has no clear solution immediately, universities are overcoming this crisis by creating many alternatives. Attracting international students is one of them. In this study, the effectiveness of photovoice was examined through the analysis of the case of the Korean-Japanese convergence cartoon class. The photo-voice method has sufficient potential as a teaching method for foreign convergence classes and can be expected to play a role as a teaching method suitable for students participating in convergence classes with different social, cultural, and linguistic backgrounds. In particular, in the convergence class, since participating students generate research materials through photo production, it can be a tool for inner exploration necessary for webtoon production and a tool for narrative inquiry for storytelling. It is expected that expanding the understanding and use of photo voice will have the methodological value of convergence classes. In addition, the teaching method using photo voice produced in the composition of photos and stories is likely to be used as an appropriate tool for convergence classes for students with different social, cultural, and linguistic backgrounds.

Objectives : This study aimed to test potential modifying effects of education on the association between apolipoprotein E ${\varepsilon}4$ (Apo E4) and cognitive decline. Methods : A community cohort(N=683) aged 65 or over completed the Korean version of Mini-Mental State Examination(MMSE-K) at baseline and two years later(1999-2001). Apo E polymorphisms were genotyped, and classified into that with or without Apo E4. Educational levels were categorized into people with or without education. Covariates included demographic(age, gender), life style(smoking, alcohol drinking), clinical (depression, sleep disorder, vascular risk factors) characteristics. Results : The association between Apo E4 and cognitive decline was significant only in the old persons with no education. The interaction term between education and Apo E4 on cognitive decline was significant(p=0.040). Conclusion : Elders with no education might be more vulnerable to the impact of Apo E4 on cognitive decline, which suggests gene-environment interaction.

Background: It has been known that ginseng can be applied as a potential nutraceutical for memory impairment; however, experiments with animals of old age are few. Methods: To determine the memory enhancing effect of red ginseng, C57BL/6 mice (21 mo old) were given experimental diet pellets containing 0.12% red ginseng extract (approximately 200 mg/kg/d) for 3 mo. Young and old mice (4 mo and 21 mo old, respectively) were used as the control group. The effect of red ginseng, which ameliorated memory impairment in aged mice, was quantified using Y-maze test, novel objective test, and Morris water maze. Red ginseng ameliorated age-related declines in learning and memory in older mice. In addition, red ginseng's effect on the induction of inducible nitric oxide synthase and proinflammatory cytokines was investigated in the hippocampus of aged mice. Results: Red ginseng treatment suppressed the production of age-processed inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-${\alpha}$, and interleukin-$1{\beta}$ expressions. Moreover, it was observed that red ginseng had an antioxidative effect on aged mice. The suppressed glutathione level in aged mice was restored with red ginseng treatment. The antioxidative-related enzymes Nrf2 and HO-1 were increased with red ginseng treatment. Conclusion: The results revealed that when red ginseng is administered over long periods, age-related decline of learning and memory is ameliorated through anti-inflammatory activity.

The core of the university policy pursued by the Moon Jae-in administration is to strengthen university competencies through the diagnosis of universities. To this end, the word structural reform evaluation is changed to strengthening the basic competencies of universities, and is trying to escape from the past reduction of pro-class capacity. Deputy Prime Minister Kim Sang-gon insisted, "We will improve the university structure evaluation, which is biased toward quantitative quota adjustment, with a diagnosis of basic university competency to support the autonomous development of the university." The Ministry of Education expressed its intention to strengthen the capacity of local universities by saying that it would also consider regional conditions in reducing the university quota due to the decrease in the school-age population so far. In the meantime, as the school-age population declined, the Ministry of Education promoted the reform of the university structure by dividing it into three cycles from 2014. This paper focuses on the problems of diagnosis of education reform and improvement measures, and tries to find out what is the desirable direction for education innovation. This paper studied the structural reform of universities following the decline of local universities. The policy alternatives in this paper are as follows. First, the contents of the government's push for university structural reform were analyzed. Second, we considered the problems of university structural reform. Third, they sought ways to develop local universities and enhance their competitiveness.

Objectives: We examined the association between social expenditures of the local government and the mortality level in Korea, 2004 to 2010. Methods: We used social expenditure data of 230 local governments during 2004 to 2010 from the Social Expenditure Database prepared by the Korean Institute for Health and Social Affairs. Fixed effect panel data regression analysis was adopted to look for associations between social expenditures and age-standardized mortality and the premature death index. Results: Social expenditures of local governments per capita was not significantly associated with standardized mortality but was associated with the premature death index (decline of 1.0 [for males] and 0.5 [for females] for each expenditure of 100 000 Korean won, i.e., approximately 100 US dollar). As an index of the voluntary effort of local governments, the self-managed project ratio was associated with a decline in the standardized mortality in females (decline of 0.4 for each increase of 1%). The share of health care was not significant. Conclusions: There were associations between social expenditures of the local government and the mortality level in Korea. In particular, social expenditures per capita were significantly associated with a decline in premature death. However, the voluntary efforts of local governments were not significantly related to the decline in premature death.

Background: Breast cancer is the most frequent malignancy of women worldwide. In Iraq, breast cancer ranks first among cancers diagnosed in women but no studies have been conducted on incidence trends. The present study of breast cancer in the country during 2000-2009 was therefore performed. Materials and Metbods: The registered data for breast cancer cases were collected from the Iraqi Cancer Registry/Ministry of Health. The significance of incidence rate trends during 2000-2009 was tested using Poisson regression. Age-standardized rates (ASR), and age-specific rates per 100,000 population were calculated. ResultS" A total of 23,792 incident breast cancer cases were registered among females aged ${\geq}15$ years, represented 33.8% of all cancers in females registered during 2000-2009. It ranked first in all the years. The median age at diagnosis was 49 and the mean age was 52 years. The incidence rate of all female breast cancer in Iraq (all ages) increased from 26.6 per 100,000 in 2000 to 31.5 per 100,000 in 2009 (APC=1.14%, p<.0001). The incidence in age groups (40-49), (50-59) and (70+) increased in earlier years and has recently (2005-2009) become stable. The incidence in age group (60-69) did not decline since 2003, while the incidence rates in the age group (15-39) started to decline in 2004. Conclusions' With the Iraqi Cancer Registry data during the period 2000-2009, the incidence of all female breast cancer in Iraq (all ages) has risen. We found rapid increase in the age specific incidence rate among age group 60-69. However, breast cancer among Iraqi women still affects younger age groups than their counterparts in developed countries. Further epidemiological research is needed to examine possible causes and prevention measures.

Making aged exercise by their age it unreasonable because there an differences of personal strength of their body. The three elements which control the aged's possibility of exercising effectivencess are the level of the physical strength in the present state, potential capacities of physical strength and age. Examined the physical strength of aged, the pliancy of body is considerably marked decline by and large and fast twitch muscle are withered. The reason why aged often do prime exercise like and infant. Aged are not fit for the speedy exercise and they can give full scope to their ability by continuing the long time exercise. The reason why aged should dwindle is mainly the retardation of recovering their fatigue which is related to the decline of oxygen activity. Anaerobic energy supply reduction makes aged be bad for severe physical exercise. Basal metabolic rate of rely on physical cellular quantity and people exercising has a high basal metabolic rate because of muscular amount. There were no decline of basal metabolic rate fellowing the age and physical non activiti influences on the atrophy of muscle.
