본 연구는 한국복지패널 1~4차년도 조사 자료를 활용하여 국민기초생활보장제도 수급탈출의 기간의존성을 분석하였다. 수급기간이 길어질수록 수급탈출률이 낮아지는 기간의존성의 존재는 복지의존을 시사하는 중요한 증거가 될 수 있다. 실증적 분석 결과, 성, 연령, 교육수준, 결혼지위, 건강상태, 취업 형태 등의 관찰된 특성을 통제한 후에도 수급기간이 길어질수록 수급탈출률이 낮아지는 현상이 관찰되지만, 관찰되지 않은 이질성을 통제하면 수급기간의 영향이 통계적으로 유의하지 않은 것으로 나타났다. 이러한 결과에 따르면, 수급기간이 길어질수록 수급탈출률이 낮아지는 현상의 상당부분은 수급자 집단의 이질성으로 인한 허위관계이고 수급탈출의 기간의존성은 크지 않은 것으로 판단된다.

Purpose: In this study, the following experiment was conducted to see how to apply the sprinter pattern in proprioceptive neuromuscular facilitation (PNF) and functional weight bearing exercise affected balance capabilities and weight bearing among chronic stroke patients. Methods: The subjects included 27 subjects who had been diagnosed with hemiplegia due to stroke. A total of 12 sessions was held, 3 sessions a week over 4 weeks, were provided to the groups. The control group received general rehabilitation program, and the experimental group performed sprinter pattern in PNF or functional weight bearing exercise. The weight bearing capability and static balance capability test was implemented by using Good-Balance System and Frailty and Injuries Cooperative Studies of Intervention Techniques, while the dynamic balance capability test was carried out by using Four Square Step Test and Timed "Up and Go". Results: The paretic/nonparetic side weight bearing by application of each exercise showed that there were no significant differences in variation among each groups on before exercise, after exercise, 2 weeks after exercise. Static balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Dynamic balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Conclusion: To put the results together, the application of sprinter pattern and functional weight bearing exercise was effective in improving static and dynamic balance capabilities. Therefore, these exercises are helpful to improve balance in patients with stroke.

Sarcopenia, the age-related muscle atrophy, is a serious concern as it is associated with frailty, reduced physical functions, and increased mortality risk. Protein supplementation is essential for preserving muscle mass, and horse meat can be an excellent source of proteins. Since sarcopenia occurs under conditions of oxidative stress, this study aimed to investigate the potential anti-muscle atrophy effect of horse meat hydrolysate using C2C12 cells. A horse meat hydrolysate less than 3 kDa (A4<3kDa) significantly increased the viability of C2C12 myoblasts against H₂O₂-induced cytotoxicity. Exposure of C2C12 myoblasts to lipopolysaccharide led to an elevation of cellular reactive oxygen species levels and mRNA expression of proinflammatory cytokines, including tumor necrosis factor-α and interleukin 6, and these effects were attenuated by A4<3kDa treatment. Additionally, A4<3kDa activated protein synthesis-related proteins through the protein kinase B/mechanistic target of rapamycin pathway, while decreasing the expression of activity and degradation-related proteins, such as Forkhead box O3, muscle RING finger protein-1, and Atrogin-1 in dexamethasone-treated C2C12 myotubes. Therefore, the natural material A4<3kDa has the potential of protecting against muscle atrophy, while further in vivo study is needed.

Purpose : The study aimed to examine gender-differences in muscle tone, elasticity, and stiffness of the erector spinae in young and old subjects. This study also aimed to assess the effect of aging on muscle tone, elasticity, and stiffness of the erector spinae in men and women, and compare the trend of the aging effect between the two gender groups. Methods : With the muscle in the relaxed state and subjects in the prone position, a myotonometer was used to quantify muscle tone, elasticity, and stiffness, of the erector spinae in 102 participants[46 males (29 young subjects, aged 22.48±2.23 years and 17 old subjects, aged 76.35±3.71 years), 56 females (40 young subjects, aged 20.38±1.43 years and 16 old subjects, aged 74.56±5.40 years)]. Results : The tone and stiffness of the erector spinae muscles were greater in men than in women for both age groups (p<.001-.01), while elasticity did not show a significant difference between men and women. For the direction of change, both male and female groups showed significantly increased tone and stiffness, and decreased elasticity with increasing age (p<.001). For age-related changes, a different tendency was observed between men and women. Men showed a greater increase in tone than women with aging. in contrast, both men and women exhibited a similar decrease or increase in elasticity and stiffness. Conclusion : Gender-differences in the erector spinae in terms of muscle tone and stiffness were observed. Regardless of the age, men had higher muscle tone and stiffness than women, but not elasticity. The erector spinae muscles showed age-related changes in all aspects of muscle tone, elasticity, and stiffness, in both men and women. Notably, men presented greater variation than women in the amount of increase of muscle tone with aging. These findings have implications for musculoskeletal therapeutic approaches, and gender-customized tuning may be indicated for designing exercise interventions to prevent and manage gender-sensitive muscular injuries or diseases and frailty.

Dementia is an umbrella term that describes the loss of thinking, memory, attention, logical reasoning, and other mental abilities to the extent that it interferes with the activities of daily living. More than 50 million individuals worldwide live with dementia, which is expected to increase to 131 million by 2050. Recent research has shown that poor oral health increases the risk of dementia, while oral health declines with cognitive decline. In this narrative review, the literature was based on the "hypothesis" that dementia and oral health have a close relationship, and appropriate oral health and occlusal rehabilitation treatment can improve the quality of life of patients with dementia and prevent progression. We conducted a literature search in PubMed and Google Scholar databases, using the search terms "dementia," "major neurocognitive disorder," "dentition," "occlusion," "tooth loss," "dental prosthesis," "dental implant," and "occlusal rehabilitation" in the title field over the past 30 years. A total of 131 studies that scientifically addressed dementia, oral health, and/or oral rehabilitation were included. In a meta-analysis, the random effect model demonstrated significant tooth loss increasing the dementia risk 3.64-fold (pooled odds ratio=3.64, 95% confidence interval [2.50~5.32], P-value=0.0348). Tooth loss can be an important indicator of cognitive function decline. As the number of missing teeth increases, the risk of dementia increases. Loss of teeth can lead to a decrease in the ascending information to the brain and reduced masticatory ability, cerebral blood flow, and psychological atrophy. Oral microbiome dysbiosis and migration of key bacterial species to the brain can also cause dementia. Additionally, inflammation in the oral cavity affects the inflammatory response of the brain and the complete body. Conversely, proper oral hygiene management, the placement of dental implants or prostheses to replace lost teeth, and the restoration of masticatory function can inhibit symptom progression in patients with dementia. Therefore, improving oral health can prevent dementia progression and improve the quality of life of patients.

스테로이드 유발 근위축은 장기간 코르티코스테로이드 요법의 일반적인 부작용이며 근육량과 기능의 현저한 감소로 이어질 수 있다. 발아된 Rhynchosia Nulubilis (GRH)는 항염증 및 항산화 특성이 있는 것으로 밝혀진 전통적인 약용 식물이다. 그러나 근 감소 억제 효능에 대하여는 보고된 바가 없다. 본 연구에서는 덱사메타손에 의해 유도된 근위축 C2C12 근관세포 모델과 마우스 모델에서 근위축 억제 활성에 대한 GRH의 영향을 평가하였다. 또한 골격근에 대한 GRH 효과의 기본이 되는 분자 경로를 확인하였다. May Grunwald-Giemsa 염색을 통한 근관 세포 염색 결과는 GRH 처리군에서 근관의 길이와 면적이 증가함을 보여주었다. 또한, muscle ring-finger protein-1 (MuRF-1)와 muscle atrophy F-box (MAFbx) 발현이 GRH 처리군에서 유의하게 감소하였다. 더욱이 덱사메타손에 의해 유도된 근위축 C57BL/6 마우스에서 트레드밀을 사용한 지구력 측정과 악력측정기를 이용한 악력 측정을 통한 근육 기능을 평가한 결과 GRH를 경구 투여한 마우스의 근육 기능이 향상되었다. 또한 이러한 결과는 근육 조직에서 GRH에 의한 MAFbx의 발현 억제를 통해 일어남을 확인하였다. 결론적으로 GRH는 MAFbx 발현을 억제하여 유비퀴틴-프로테아좀 경로를 차단함으로써 덱사메타손에 의해 유발된 근위축을 개선할 수 있을 것이다.
