Background: Physical activity (PA) is critical for maintaining the health and well-being of older people in community and also institutional settings. The purpose of this study was to examine the current status of PA and related individual and organizational factors among older nursing home residents with and without dementia. Methods: This is a secondary data analysis study of a nationwide survey of 92 long-term care facilities in Korea, and the study sample includes older residents with dementia (n= 753) and without dementia (n= 480). The level of PA was measured by PA time and whether or not residents had an outdoor activity over the past 3 days. Multi-variate, multi-level analyses were conducted. Results: More than half of the sample in both groups had no or less than 1 hour of PA. About one out of four older people in our sample had no outdoor activity over the past 3 days regardless of whether or not they had dementia. Among the people without dementia, several individual-level factors were associated with PA, including dependency for activities of daily living, social activity participation, and caregivers' belief in the functional improvement of residents. Unlike the non-dementia group, individual- and organizationallevel factors including staffing level and having the relevant equipment for PA were associated with PA among those with dementia. Conclusion: Study findings provide evidence on the lack of PA among older nursing home residents, and the importance of institutional capacity with regard to human resources and physical equipment for promoting PA among people with dementia, in particular. Policies and supports are needed to promote the implementation of healthy aging programs including PA for older nursing home residents. Such programs should be person-centered with consideration to the physical and cognitive status of individual residents.

This study aimed to explore the status of food service outsourcing behavior of long-term care institutions (LTCIs) through a cross-sectional survey using a questionnaire administered between July 16th and August 7th, 2020. The survey respondents were either dietitians or facility managers, who worked at 731 nursing homes, 477 group homes, and 673 day-care centers. Approximately 25.9% of nursing homes, 11.7% of group homes, and 33.1% of day-care centers used a managed-services company to operate their food service units. The main reason for outsourcing food service by nursing homes was related to the staffing of dietitians and cooks, whereas group homes and day-care centers outsourced food services due to factors relating to meal costs and the cooking process. Almost all the LTCIs entered into private contracts for outsourced food services. Only a few food service contracts included the types of meals, nutrition standards such as protein and calories per meal, and the parameter or ratio of food cost. Of the respondents, 84.5% from nursing homes, 87.5% from group homes, and 87.1% from day-care centers agreed that the quality of outsourced food services of the LTCIs should be regulated. Meals are essential for maintaining the health and functional status of LTCI users. As more LTCIs outsource their food services, we suggest the following: (1) Increasing the minimum dietitian staffing standards for LTCIs as per the Welfare of Senior Citizens Act and requiring at least one dietitian for every nursing home, (2) Making it mandatory to use a standard food service contract template when drafting food service contract, and (3) Developing realistic standards for food service operations considering the size and operation type of the LTCIs.

Purpose: This study aimed to construct a structural equation model to explain and predict factors affecting the health-related quality of life (QoL) in female rheumatoid arthritis (RA) patients based on the health-related QoL model by Ferrans et al. (2005) and a literature review. Methods: Patients (N=243) who were either registered members of an internet cafe composed of patients with RA or rheumatology outpatients at two tertiary general hospitals in Busan, Korea, were recruited via convenience sampling. Data were collected from July 2 to September 9, 2021, and the survey was conducted using a web-based questionnaire. The data were analyzed by SPSS and AMOS 26.0. Results: The goodness-of-fit statistics of the final model exhibited good results (χ²/degree of freedom=2.68, Turker-Lewis index=.94, comparative fit index=.96, standardized root mean-squared residual=.04, root mean- square error of approximation=.08), and 11 out of 14 paths of the model were supported. The squared multiple correlation, which reflected the explanatory power of the environmental characteristics, symptoms, functional status, and perceived health status on health-related QoL, was 80%. In the hypothesis model, 10 paths had significant direct effects, 6 paths had significant indirect effects, and 12 paths had significant total (direct and indirect) effects. Conclusion: Considering that factors directly affecting the health-related QoL of female patients with RA were social support, symptoms (fatigue and depression), resilience, and perceived health status, and that resilience was the most influential factor, clinicians can encourage resilience. Hence, to improve the health-related QoL of female patients with RA, continuing management is necessary, using various intervention methods that focus on enhancing resilience from the early stage to the end of treatment for RA.

Background: Oral frailty is defined as the functional decline of the oral function due to aging, and it is associated with frailty and chronic disease. Most of the frailty intervention is for adults aged 65 years and older. However, early intervention for preventive disorder is most important. The objective of this study was to identify the age at which oral frailty surpass the "normal" range. Methods: This cross-sectional study included 719 adults (aged 30~89 years) residing in Gangwon province in May 2023. Risk of oral frailty was assessed using criteria from The Korean Academy of Geriatric Dentistry including oral function such as swallowing and mastication, and frailty. Frailty was assessed using the Kihon Checklist. To determine when oral frailty surpass the "normal" status, statistical analysis including chi-squared tests and multiple logistic regression analysis were performed using R (ver. 4.3.1). Results: There were 388 (54.0%) individuals who had a "normal" status risk of oral frailty. The risk of oral frailty was higher in the 50~54 age group compared to the 30~34 age group (odds ratio [OR] 0.50, 95% confidence interval [CI] 0.28~0.91), after adjusting for gender, education, income, occupation, and frailty (OR 0.46, 95% CI 0.22~0.94). This means that from 50~54 years old, regardless of gender, education, income, occupation, or frailty condition, there is a distinction from the "normal" status. Conclusion: We found that intervention for oral frailty is needed starting from age 50 years. This is the stage where early indications of oral frailty become apparent. Early intervention for oral frailty can lead to a decrease in the prevalence of diseases and medical expenditure. Therefore, early intervention in middle-aged adults of oral frailty is necessary to improve the quality of life related to oral health.

This study examined the preference and the purchase intention of male and female from 20s through 405 to smart phones. This study verified the differences between the groups according to the socio-demographic factors, the usage pattern of mobile phone, and the perceived cost and the expected benefit. The analysis of the relative influence of those relevant factors was followed. The summaries of this study are as follows; First, the high level factors in purchasing smart phones were the perceived cost and the expected benefit pointed over 3.82. It means that they arc interested in smart phones highly, and if they can support to buy smart phones and situations can be permitted, they would like to buy them. Second, the differences between groups of the preference and the purchase intention were found according to the ages, the marital status and the education level. The results showed that those preference and the purchase intension were measured high at the group of the 20s-30s, the married, and the higher educational level of collage students. Third, expected benefit on smart phones was shown to be divided into two characterized factors through factor analysis. One was 'functional expected benefit' and the other was 'emotional expected benefit'. The functional and the emotional benefit on the using of smart phones were presented high level in group of over graduated students. Forth, the results of the stepwise multiple analysis, which was carried out to find out the influencing factors on the preference and the purchasing intension to smart phones, showed that the most effective factor was the functional expected benefit. The self-expressive propensity, and the education level were followed sequentially. The purchase intention was influenced by both of the functional and the emotional expected benefit. The result of this study shows that the level of the consumer's perceived cost(economic, psychological) and the expected benefit were measured high at the same time. That means that it is necessary to make the consumer information and communicating smoothly in order to lower the cost and enhance the benefit. In addition, This study has its meaning because it found out that functional expected benefit is a factor which has an influence on the Consumer Preference and Purchase Intention on Smart phone. If consumer's function requirements on smart phone are satisfied, it will be able to reduce the consumer problems and increase the consumer satisfaction. The result of this study would be applicable when Smart Phone is used as one of the auxiliary tools for smart consumption.

차세대 염기 서열 분석 기술의 적용은 빠르게 식물 유전체학의 지식을 확장시킴으로 기능유전자 연구의 발전을 도모하고 있다. 특히, 밀의 기능유전체학의 발전은 기존의 염기서열 분석 기술로는 가능성이 없어 보였다. 하지만 NGS의 발전은 고품질 보통밀의 RefSeq를 완성뿐만 아니라 다양한 밀 계통들의 재염기서열분석을 가능하게 한다. 현재 이렇게 얻어진 고품질 유전정보와 유전적 다형성이 밝혀진 유전자원의 이용으로 밀 기능유전체 연구가 새로운 단계로 접어들고 있다. NGS 기술 및 reverse genetics의 발전은 앞으로 전세계에 펼쳐져 있는 야생형 밀과 재배종 밀 계통들의 유전적인 다양성 분석을 가능케 하고 밀의 유전과 진화 과정을 깊게 이해하는데 큰 도움이 될 것이다. NGS 기술의 사용과 생물정보학의 결합은 타 작물에 비해 뒤쳐진 밀의 기능유전체 연구 속도를 가속화할 것이다. 기능유전체 연구를 활용한 밀 육종의 시대가, 애기장대 및 벼 분야와 같이, 다가오고 있다.
