This study investigated the life anxiety and current situation of Yanbian residents under the adjustment of China’s epidemic prevention and control measures, and analyzed 235 questionnaire data with SPSS23.0. The results of independent T-test based on demographic sociological characteristics show that residents' anxiety in villages about income security and living goods security is signific-antly higher than that of residents in cities; The drug security anxiety of the elderly was significantly higher than that of the young; The income security anxiety of the people with low educational level is significantly higher than that of the people with high educational level; The anxiety scores of economic income security, medical security and drug security of low-income groups were significantly higher than those of the control group; The gender difference is not obvious in all variables. The life satisfaction of the high-income group and the elderly group was significantly higher than that of the control group. In addition, economic income level, medical security and epidemic hazards significantly affect the life satisfaction of Yanbian residents. Therefore, all levels departme nts in Yanbian should provide targeted services for different groups of people, and improve the residents’ quality of life in Yanbian by implementing measures including promoting economic development, strengthening medical treatment capacity, and reducing epidemic hazards.

With the continuous deterioration and rebound of Novel Corona Virus Disease worldwide, the impact on all areas of society can not be underestimated. In particular, the normalization of the pandemic has also had a profound impact on the development and adaptation of adolescents from overseas working families. There are a large number of special social groups, adolescents from overseas working families in Yanbian, China. Affected by severe pandemic normalization, these adolescents have been separated from their parents for a long time, suffering from troubles and many other problems. School adaptation is an important measure of adolescents' social adaptability. In order to explore the influencing factors of school adaptability of Chinese-Korean adolescents from overseas working families, this study did a questionnaire survey on them through the method of cluster sampling. A total of 602 valid questionnaires were collected. Among them, there are 289 adolescents from overseas working families, accounting for about 48%. The correlation and multiple regression analysis were carried out with SPSS 24.0. The results show that: 1) There is a significant correlation between the main factors; 2) Self-esteem and depression in personal factors, parental attachment in family factors, and teacher-student relationship and school performance in school factors have a significant impact on adolescents‘ school adaptability. Finally, this paper puts forward a system to strengthen the school adaptability of adolescents from Chinese-Korean overseas working families, as well as some specific intervention measures.

The level of aging in Yanbian area has surpassed that in China so that the situation is very serious. With the high proportion of the elderly living alone, the poor elderly in Yanbian area and the premise of insufficient provision for the aged, there are many problems, such as the diversification of the elderly problem, the disparity of the elderly individuals, the weak awareness of the old-age planning and the weak subjectivity of the elderly. The home-based care for the elderly in Yanbian community is also facing great challenges. There are some problems in Yanbian community pension service, such as insufficient special funds, low level of professionalism, contradiction of social service delivery system, and lack of a joint force among the main bearers of social work for the elderly. Therefore, it is necessary to establish a "medical treatment+supporting+nursing" combined, "four in one" multi-linked community home service model and set up a service network system for the elderly to realize the diversification of the service carriers for the elderly, fulfill the diversification and individualization service needs of the elderly groups in Yanbian in the process of service specialization to meet the diversified and individual service needs of the elderly groups.

Background: Fall-related injuries in older adults are a major health problem, and the risks and mechanisms of these injuries should be affected by race, culture, living environment, and/or economic status. Objects: Research articles have been systematically reviewed to understand fall-related injuries in older adults in South Korea. Methods: 128 published research papers have been found through the Korea Citation Index and the Korean Studies Information Service System, and reviewed in various perspectives, including incidents, fall death rates, medical costs, causes, injury sites and types, locations where falls occurred, prevention strategies, scholarly fields interested in fall injuries, and the role of physical therapy. Results: Fall-related injuries were found to be more common in women than in men, and the number of incidents increased with age, with the highest rate found in individuals over 85 years old. Risk of fall injury was associated with education level, comorbidities, and fear of falling. Common places where falls occurred included the bathroom, living room, stairs, and hallway. Common types of injury included bruises, fractures, and sprains in the lower extremities. Intervention strategies included exercise programs, education, and protective clothing. Scholarly fields interested in fall-related injuries in older adults included medicine, nursing, physical therapy, occupational therapy, physical education, pharmacology, oriental medicine, biomedical engineering, design, clothing, and textiles. Physical therapy intervention using proprioceptive neuromuscular facilitation has been used to improve one’s balance. Conclusion: Any movement during the activities of daily living can lead to a fall. Physical therapists are highly educated to analyze human movements and should be involved in more research and practices to solve fall-related injuries in older adults.

노린재목(Hermiptera)에 속하는 물장군(L. deyrollei)은 수서곤충 중 가장 대형 종으로 습지, 논, 농수로 등에서 서식하며 담수어류나 양서류 유생 등을 포식하는 육식성 곤충이다. 본 연구는 2015년 5월부터 7월까지 제주도내 물장군 서식지(서귀포시 성산읍 난산리(A), 신천리(B)) 2곳과 개체수가 줄어드는 서식지(제주시 구좌읍 덕천리(C), 한림읍 상대리(D)) 2곳 및 물장군이 서식하지 않는 습지(한경면 용수리(E))에 서식하는 담수어류 및 양서류 유생을 조사하였다. 조사방법은 각 습지 당 10분씩 포충망을 이용하여 채집을 실시하였다. 조사결과 A습지는 5월에 북방산개구리(Rana dybowskii) 100개체, 6월에 참개구리(R. nigromaculata)와 청개구리(Hyla japonica)가 1개체, 9개체 및 7월에 1개체, 4개체가 조사되었다. B습지는 5월(북방산개구리 100개체), 6월(참개구리 9개체, 미꾸리(Misgurnus mizolepis) 2개체), 7월(참개구리 및 미꾸리가 11개체, 1개체)가 조사되었다. C습지는 5월(북방산개구리 6개체, 참개구리 22개체, 청개구리 38개체, 미꾸리 4개체, 제주도롱뇽(Hynobius quelpartensis) 1개체)가 조사되었고, 6월에 청개구리 4개체, 7월에 참개구리 2개체가 조사되었다. D습지는 5월에 북방산개구리 40개체, 6월에 참개구리, 청개구리, 미꾸리가 각 1개체, 4개체, 10개체가 나타났으며, 7월에는 채집된 개체가 없었다. 마지막으로 E습지에서는 6월에 제주도롱뇽 2개체만 조사되면서 물장군이 서식하는 습지에서는 담수어류 및 양서류 유생의 개체수 및 시기에 따른 종 변화가 다양한 것으로 판단되며, 먹이원이 풍부하지 않거나 7월 이후에 사라지는 습지에서는 물장군이 서식 및 번식하기에는 부적절하다고 사료된다.

Spinal pain is a symptom caused by changes of the vertebral column or its adnexa. Sometimes spinal pain cannot be treated, especially in case of multiple pain lesions, because of its difficulty in evaluating original causes which contributes to the symptoms. Thus, the precise localization of the lesion causing symptoms is very important for targeted treatment. However, the diagnosis based on limited screening test including physical evaluation and radiological finding may lead to misdiagnosis of the actual lesion causing symptoms, failure of treatment, and unnecessary surgery. From this point of view, nonsurgical interventional for spinal pain can be helpful to diagnose the precise cause of spinal pain. We report several cases that nonsurgical interventional therapy which diagnosed the precise lesion that cause the spinal pain and treated successfully with nonsurgical interventional therapy for diagnostic purposes with therapeutic purpose.
