Understanding sciences behind fall-related hip fractures in older adults is important to develop effective interventions for prevention. The aim of this review is to provide biomechanical understanding and prevention strategies of falls and related hip fractures in older adults, in order to guide future research directions from biomechanical perspectives. While most hip fractures are due to a fall, a few of falls are injurious causing hip fractures, and most falls are non-injurious. Fall mechanics are important in determining injurious versus non-injurious falls. Many different biomechanical factors contribute to the risk of hip fracture, and effects of each individual factors are known well. However, combining effects, and correlation and causation among the factors are poorly understood. While fall prevention interventions include exercise, vision correction, vitamin D intake and environment modification, injury prevention strategies include use of hip protectors, compliant flooring and safe landing strategies, vitamin D intake and exercise. While fall risk assessments have well been established, limited efforts have been made for injury risk assessments. Better understanding is necessary on the correlation and causation among factors affecting the risk of falls and related hip fractures in older adults. Development of the hip fracture risk assessment technique is required to establish more efficient intervention models for fall-related hip fractures in older adults.
Adenoid cystic carcinoma(ACC) is an uncommon tumor of the head and neck. It is one of the most common malignant tumor of the salivary glands. Although ACC has clear pathologic features, it can be diagnosed as a benign lesion in terms of cytological and radiologic aspects. In this paper, we report a rare case of ACCACC on tongue that is diagnosed as ACC but appears as a benign lesion in cytological and radiologic views.
이 연구의 목적은 「산림총서」 및 언론보도, 북한과학기술네트워크(http://www.nktech.net/) 등의 문헌자료를 이용하여 1960년부터 2019년까지 북한 산불의 시공간적 발생경향과 산불 분야 연구동향을 파악하는 것이다. 북한의 산불 발생이력은 2000년대를 기점으로 대외적으로 보고되기 시작하였으며, 산불 보도건수는 산림율과 정의 상관관계를, 인구밀도 및 산림황폐화율과는 부의 상관관계를 보였다. 시기적으로는 봄과 가을, 지역적으로는 동해안 지역에 산불이 집중되는 경향을 보였다. 동해안 지역에 산불 발생이 집중되는 이유는 높은 산림율과 낮은 인구밀도로 인해 감시와 통제에 자유로운 방화가 북한지역 산불의 주원인이 될 수 있음을 시사하였다. 산불 관련 논문은 2000년대를 기점으로 다수 발행되었으며, 김정은 집권시기에 가장 많은 논문이 발행되었다. 연도별 논문 발행편수는 산불 보도건수(n-3년 및 n-5년 이동평균)와 정의 상관관계를 보였으며, 산불 발생빈도가 증가함에 따라 산불이 사회적 문제로 확대되면서 관련 연구가 수행되었던 것으로 확인할 수 있었다. 이 연구의 결과는 향후 산불 분야의 남북 교류협력에 있어 산불 공동 관리·대응 역량 및 상호 협력체계를 발전시킬 수 있는 기초정보를 제공할 수 있을 것으로 기대된다.
이 연구는 국내 대학 엘리트 축구선수를 대상으로 스포츠 손상과 관련된 선행 연구를 토대로 스포츠 손상 경험과 부위를 살펴보고 그에 따른 효과적인 재활프로그램의 방향성을 제시하고자 실시되었다. 이 연구에 참고자료로 이용된 6편의 연구는 한국학술정보서비스(KISS), 학술연구정보서비스(RISS), 학술데이터베이스서비스(Dbpia)에서 검색어 "대학축구선수 & 손상", "축구 & 스포츠손상"이라는 검색어를 통해 검색된 연구 중 2000년부터 2021년까지 발표된 연구를 중심으로 전문가가 연구에 적합한 연구만 선별하여 연구를 진행하였다. 이 연구에서 분석한 대학축구선수의 손상 경험은 144명의 축구선수 중 120명(83%)으로 나타났고, 손상 횟수는 손상 경험이 있는 선수에게 있어 2.58회로 나타났다. 또한, 각 연구에서 보고된 손상 부위는 하지에 주로 나타나는 경향을 보였는데, 도진학 연구에서는 80.6%, 김은국 등 연구에서는 61.8%, 김태규 등 연구에서는 90%, 김한범과 권순용 연구에서는 86.6% 등으로 나타났다. 결론적으로 대학축구 선수에게 있어서 무엇보다 중요한 것은 훈련 부상을 줄이는 것에 중점을 두어야 하며, 개인적인 측면에서 손상에 대한 의학적이고 과학적인 재활프로그램이 진행되어야 한다. 또한, 적절한 트레이닝 규칙을 시행하고 경기 중에서는 페어플레이에 집중하는 것과 같은 예방적 개입을 분석개발하여 경기 관련 부상 발생을 줄이는 것이 무엇보다 중요할 것으로 사료된다.
Cemento-ossifying fibroma is a benign fibrous lesion with an unknown cause, mostly asymptomatic, painless swelling of the affected jaw. This is a case report on a cystic lesion found on radiographic examination in a patient with an extraction of mandibular left tooth. A 29-year-old female was referred to Pusan National University Dental Hospital due to a radiopaque lesion in the left mandible. On the medical history examination, the left lower mandibular tooth had been extracted 4 years ago, and there were no specific findings in the general medical history. According to histopathologic findings, along with proliferation of spindle cells, cementum-like substances were observed along with irregularly shaped osseous calcified substances containing osteocytes in the cellular fibrous connective tissue. In this study, we report a case that showed cystic changes due to tooth extraction, which made it complicated to determine the differential diagnosis from the existing fibrous-osseous lesion.
Dentigerous cyst is considered one of the representative cystic lesions, which accounts for approximately 15%-30% of the odontogenic cysts. Although its recurrence rate is low, a small proportion of dentigerous cysts converted into ameloblastomas, squamous cell carcinomas, and mucoepidermoid carcinomas. Here we present an uncommon case characterized by histopathological transformation from a dentigerous cyst to an ameloblastoma, and further investigate the factors contributing to its conversion.
This study aims to review observational methods for assessing postural loads such as OWAS, RULA and REBA, and to compare them, based on the literature survey. The literature was searched through academic database of ScienceDirect using the key words of observational methods, OWAS, RULA and REBA. The results exhibited that of the thee methods, RULA was cited in the literature and applied to manufacturing industries the most frequently. Although it has been known that RULA is appropriate for assessing upper body postures, it has been applied to healthcare and social work activities, agriculture, forestry, fishing, construction, mining and quarrying, which require unstable lower limb postures. The countries where more number of relevant studies have been carried out were USA, India, Brazil, UK, etc. It was recommended that of the three techniques, RULA may be better for assessing postural loads, because it evaluated postural loads more highly, irrespective of industry, work type and lower limb postures, and its assessment results had higher agreement rate with experts’ assessments than those of OWAS and REBA. It is expected that the results of this study will be used as a guideline for selecting an appropriate observational method.
Worldwide, oral cancer accounts for 2%–4% of all cancer cases. It is estimated that more of 90% of all oral neoplasms are oral squamous cell carcinoma (OSCC). The aims of this study were to evaluate follow-up outcomes in patients with OSCC invading the mandibular body bone who underwent primary radical resection and reconstructive surgery by fibular free flap or CAD-CAM T-mesh with pathological study on two cases. In this article, two cases of mandibular reconstruction in patients with OSCC invading the mandibular body bone are reported. A 68-year-old male patient visited the authors’ clinic with pain on the left mandibular region. After wide excision and segmental mandibulectomy on the mandibular OSCC, a enterocutaneous fibular free flap from right leg was used to cover the intraoral mucosal defect. The other 51-year-old female patient visited the authors’ clinic with pain on the right mandibular region. After wide excision and segmental mandibulectomy on the mandibular OSCC, reconstruction was done with a reconstruction plate and a fibula free flap from right leg. Unfortunately, fibular free flap was lost due to infection of the flap at post-operative 1month, secondary reconstruction using a custom-made type T-mesh and iliac PCBM was done to repair on the mandibular defect after four years postoperatively. The customized CAD-CAM T-mesh was made prior to the operation according to mirror image of remained jaw. Patients with OSCC invading the mandibular body bone are required an accurate segmental mandibulectomy immediate reconstructive surgery with various methods and followed by adjuvant radiation with or without chemotherapy in order to improve the quality of life through the restoration of the oral function and esthetics after surgery. Postoperative CCRT was determined according to the final pathologic findings such as lymph node metastasis and main lesion free margin safety, and this has an essential relationship in the prognosis of postoperative recurrence. We reviewed reliable treatment options on two patients of OSCC in mandible with pathologic findings.Worldwide, oral cancer accounts for 2%–4% of all cancer cases.

Leiomyoma is a Benign tumor that develops in smooth muscles and is known to occur more in women in age between 40s and 50s. The most common site of leiomyoma is uterine (95 %). It occurred in oral region is very rare about 0.065 % and usually developed in upper and lower lips, palatal site, buccal site and tongues. The prognosis of leiomyoma is very positive. The recurrence rate is extremely low to 2 % below. In present study, we report a 78 year old female with a lesion located in temporomandibular joint cavity which was suspected as a malignant tumor. Additionally, this paper reports contains a literature review of oral leiomyoma. Rare location with painless leiomyoma of present case will be considered to be caution.
While efforts have been made to address fall-related injuries in older adults, the problem is unsolved to date. The purpose of this review is to provide a guideline for fall and injury prevention programs in older adults, based on evidence generated over the past 30 years. Research articles published between 1990 and 2020 have been searched on PubMed, using keywords, including but not limited to, falls, hip fracture, injuries, intervention, older adults, prevention, hip protector, vitamin D, safe landing strategy, and exercise. Total of 98 articles have been found and categorized into five intervention areas: exercise program, hip protector, safe landing strategy, vitamin D intake, and compliant flooring. Furthermore, the articles have been rated based on their study design: class 1, randomized controlled trials; class 2, nonrandomized controlled trials; class 3, experimental studies; class 4, all other studies. Exercise programs have shown to decrease the risk of fall, and associated injuries. Hip protectors, safe landing strategy, and vitamin D intake were effective in reducing a risk and incidence of hip fracture during a fall. Furthermore, compliant flooring has also decreased hip fracture risk without affecting balance. An integrated approach combining exercise program, wearing a hip protector, teaching safe landing strategies, scheduled vitamin D intake, and compliant flooring installation, is suggested to address fall-related injuries in older adults.
Systematic literature reviews (SLR) are very important to track the extent to which studies related to the formulation of Halal Catering on board have been previously studied by previous scholars. Therefore, the SLR study requires a clear and detailed understanding concerning the study direction for each selected article by analyzing the scope of the study and its dimensions as the main emphasis whether it has been discussed by any previous scholar or otherwise. Through the basis of the analysis of literature reviews will enable the specific detection of the title of the study. Even SLR analysis is also able to compare in terms of the year the article was published by comparing the differences in scope and dimensions of each article by selected scholars referred to 16 scholars from the year 2012 until 2017. Regards to methodology, SLR emphasised into five stages such as i) Time Frame, ii) Selection of a database, iii) Journal selection, iv) Article selection and v) Literature review analysis. Analysis, discussion, and findings will be focusing on the scope, dimensions, and years of studies by using figures, tables as facilitators of analysis and findings. Hence, the role of Halal institutions will be able to assess its ability to form halal rules with the involvement of stakeholders and the scope that has been affected in detail.
Many studies utilizing dogs, cats, birds, fish, and robotic simulations of animals have tried to ascertain the health benefits of pet ownership. some research has associated viewing fish in aquariums with positive well-being outcomes; as there is no physical contact with the animal, this form of interaction carries less risk. From the points mentioned above it is clear that having an aquarium can significantly influence life and health. Aquariums can heal a stressed out body and mind making it clear of all unwanted thoughts which reduces the stress and blood pressure. Watching beautiful fishes swim in the aquarium provides a break to the viewer from all the routine work in life and cause a sense of relaxation or calmness. It helps kids to gain knowledge about a variety of fishes and learn how to care for them. Hyperactive kids become quiet and calm. These positive effects on health are caused due to secretion of neurochemicals influenced by gazing at colorful active fishes swimming in the tank. The remaining studies involved novel interactions with fish in home or public aquariums. Outcomes relating to anxiety, relaxation and/or physiological stress were commonly assessed; evidence was mixed with both positive and null findings. Preliminary support was found for effects on mood, pain, nutritional intake and body weight, but not loneliness. All studies had methodological issues and risk of bias was either high or unclear. Review findings suggest that interacting with fish in aquariums has the potential to benefit human well-being.
Purpose: Recently, with the increasing demand for a evidence-based practice model in the health care area, qualitative meta-synthesis studies that provide a comprehensive understanding of phenomena of interest has increased. This study was conducted to understand the concept of qualitative meta-synthesis and guide the application of appropriate methods. Methods: This study is a literature review to address and analyze concepts and methods used in qualitative meta-synthesis studies. Results: The definition and purpose of qualitative meta-synthesis, philosophical background, procedures and outcomes are described. And the meta-ethnography, which is widely applied, was described. In addition, grounded theory, critical interactive synthesis, and meta-study were briefly introduced. It is also desirable to evaluate the quality of the primary research paper by utilizing evaluation criteria and evaluation tools to select the primary research paper, which also affects the quality of qualitative meta-synthetic studies. It is necessary for the researcher to recognize the epistemological difference in qualitative meta-synthesis, to consider saturation of the primary research paper, and to minimize the decontextualization of the primary research paper. Above all, the creative interpretation of researchers should provide expanded knowledge and insights into the research area. Conclusion: By clarifying the purpose of qualitative meta-synthesis, the researcher should ensure justification for performing qualitative meta-synthesis. Researchers also need to make efforts to ensure methodological transparency in order to overcoming the limitations of qualitative meta-synthesis.
Odontogenic keratocyst (OKC), also known as keratocystic odontogenic tumor, is a distinct clinicopathologic lesion that can be clearly identified by histologic examination. Clinically, OKC is characterized by a high recurrence rate. This report describes a rare case of OKC with mural calcification in the maxilla of a 47-year-old male patient. Orthopantomography and Cone Beam Computed Tomography showed full opacification with calcification and lateral wall resorption in the left maxillary sinus, destroying the sinus floor. Hard tissue deposits have rarely been reported in the connective tissue walls of OKC. The importance of calcified material formation to the biological behavior of OKCs is unclear. Although its prognostic value has not been studied, the presence of calcification materials does not appear to increase the risk of recurrence. Study of a number of samples would be needed to determine the nature of the correlation between the presence of calcified materials and recurrence.

With few reported cases, cystic hygroma is known to occur mainly in patients under the age of two years. Cystic hygroma can eventuate in any area; however, it mostly occurs in the cervicofacial area. If cystic hygroma occurs in this area, then the lesion may be related to the vital structures. Therefore, a complete surgical resection may be impossible and difficult to perform. This incident affects the high recurrence rate of cystic hygroma. The purpose of this report is to present a case of cystic hygroma occurring on the left side of the neck of a 47-year-old male patient as well as a review of literatures.
