한국 노인의 낙상 실태와 위험요인: 일부 지역의 인구비례 할당 표본 조사

임재영,박원범,오민균,강은경,백남종 대한노인병학회 2010 Annals of geriatric medicine and research Vol.14 No.1

Background: To investigate the occurrence of falls and their consequences in a representative population and to identify risk factors of falls in the elderly. Methods: The study participants were community-dwelling elderly people aged 65 years or old as a population based sample of one large city. A total of 828 people 65 years or older participated in this study. They were interviewed over the telephone by a trained interviewer using a structured questionnaire to obtain a fall history and details of their most recent fall including date, time, place, circumstances, and associated injury. As for risk factors for falls, we asked about living arran- gement(with family or alone), alcohol intake, exercise, visual and hearing impairments, memory and sensory problems, lower limb weakness, and arthritis symptoms. Fear of falling and fear-related activity restriction were also evaluated. Results: The incidence of falls during the last one year was 13.0%. Women experienced falls more frequently. Falls occurred mainly in spring and summer and from 10 AM to 3 PM. Common causes of falls were slipping and tripping. 14.9% of those who fell suffered consequent fractures. Being female was a significant risk factor for falls; and females tended to get injured more severely following a fall. During the recent one year, decreased proprioception in the lower extremity was a significant risk factor for falls. Those with histories of falls, and especially women, tended to limit their activities due to the fear of falling. Conclusion: Overall, it appears that elderly women are more greatly affected by falls at several levels. Female partici- pants fell more frequently and suffered more severe consequences. Fall-related injuries and risk factors for falls disproportionately affected women. And, being female and any amount of decreased sensation in the feet were significant risk factors for falls. 연구배경: 일부 지역의 인구 비례할당 표본 조사를 통하여노인의 낙상의 발생과 그 결과를 조사하고 낙상 위험 인자를확인하고자 하였다. 방법: 한 지역의 65세 이상 인구의 비례할당 표본을 대상으로 숙련된 조사요원에 의한 전화조사를 통해 낙상발생 날짜,시간, 장소, 상황 등에 대하여 조사하였다. 그리고 관련된부상 등 낙상 결과에 관한 조사와 낙상에 대한 위험인자,즉 독거 유무, 알코올섭취량, 운동량, 청각과 시각장애, 기억력, 감각 문제, 하지 위약 및 관절염 증상 등을 물어보았다. 또한 낙상의 두려움과 두려움 관련 활동제한도 평가하였다. 결과: 지난1년 동안 낙상의 발생률이 13%였고, 여성의발생률이 더 높았다. 낙상은 주로 봄이나 여름 10시~3시사이에 주로 나타났다. 낙상의 일반적인 이유는 미끄러짐과걸려 넘어짐이었다. 14.9%의 사람이 골절상을 입었다. 여성이 낙상의 중요한 위험요소였는데, 여성의 경우 더 심각하게부상을 나타내는 경향이 있었다. 최근 1년 동안 낙상의 주된위험요소로는 하지의 고유수용체감각의 감소였다. 특히 여성에서 낙상에 대한 두려움 때문에 활동을 제한하는 경향을보였다. 결론: 노인에서 여성 자체가 낙상의 위험인자이다. 여성노인이 더 자주 넘어지고 낙상 후에 더 나쁜 낙상 결과를갖게 되며, 낙상 관련 두려움과 이로 인한 활동제한도 더많았다.

환형 연소기 시스템에서 비연소 3D 음향장 해석

임재영,김대식 한국추진공학회 2017 한국추진공학회지 Vol.21 No.6

The current study has developed an in-house 3D FEM code in order to model thermoacoustic problems in an annular system and compared the acoustic field calculation results with measured ones from a benchmark combustor. From the comparison of calculation results with the measured data, the current acoustic code could successfully capture the various acoustic mode found in the annular system. In addition, it was found that the transverse waves in the combustor were strongly affected by the nozzle acoustic impedances, as well, the pressure distributions were closely related with the combustor acoustic pressure field. 연구에서는 환형 시스템에서 열음향 문제를 모델링하기 위하여 자체 3D 유한요소해석을 모델 개발을 통하여 음향장을 해석하였고, 다양한 음향 모드를 벤치마크 연소기의 실험 결과와 비교/검증하였다. 비교 결과, 본 해석에서 사용된 음향장 해석 코드는 환형 시스템에서 실험으로 계측된 다양한 음향 모드들을 예측하는데 성공하였다. 또한 연소실의 횡방향 모드는 노즐의 음향 경계 조건의 영향을 크게 받게 되고, 노즐에서의 압력 분포 역시 연소실의 압력장과 밀접한 관련이 있는 것으로 나타났다.

Therapeutic potential of eccentric exercises for age-related muscle atrophy

임재영 한국한의학연구원 2016 Integrative Medicine Research Vol.5 No.3

Recent studies have focused on evidence-based interventions to prevent mobility decline and enhance physical performance in older adults. Several modalities, in addition to traditional strengthening programs, have been designed to manage age-related functional decline more effectively. In this study, we reviewed the current relevant literatures to assess the therapeutic potential of eccentric exercises for age-related muscle atrophy (sarcopenia). Age-related changes in human skeletal muscle, and their relationship with physical performance, are discussed with reference to in vitro physiologic and human biomechanics studies. An overview of issues relevant to sarcopenia is provided in the context of the recent consensus on the diagnosis and management of the condition. A decline in mobility among the aging population is closely linked with changes in the muscle force–velocity relationship. Interventions based specifically on increasing velocity and eccentric strength can improve function more effectively compared with traditional strengthening programs. Eccentric strengthening programs are introduced as a specific method for improving both muscle force and velocity. To be more effective, exercise interventions for older adults should focus on enhancing the muscle force–velocity relationship. Exercises that can be performed easily, and that utilize eccentric strength (which is relatively spared during the aging process), are needed to improve both muscle force and velocity.

신생아에서 급성 복증으로 발현된 Meckel 게실 1예

임재영,장선화,조재민,고경혁,박은실,서지현,박찬후,우향옥,윤희상,Lim, Jae Young,Jang, Sun Hwa,Cho, Jae Min,Ko, Gyung Hyuck,Park, Eun Sil,Seo, Ji Hyun,Park, Chan Hoo,Woo, Hyang Ok,Youn, Hee Shang 대한소아소화기영양학회 2005 Pediatric gastroenterology, hepatology & nutrition Vol.8 No.2

출생 후 건강하게 지내던 중 생후 9일째 급성 복증 및 장 폐쇄의 증상으로 내원한 남아에서 시험적 개복술 시행하여, Meckel 게실 천공과 장 유착을 발견하고 수술적으로 제거한 후 회복된 증례이다. 병리 소견상 경한 게실 염과 정상 장 점막 소견을 보여 자발적 Meckel 게실 천공이라고 추정 되는 증례이다. 신생아시기에 자발적 Meckel 게실 천공은 매우 드물지만 심각한 질환이다. 따라서 신생아 시기에 급성 복증 증상을 보일 때 반드시 감별 진단 목록에 Meckel 게실을 포함시켜야만 한다. Meckel's diverticulum is generally acknowledged to be the most prevalent congenital anomaly of the gastrointestinal tract. The preoperative diagnosis of Meckel's diverticulum is difficult, especially in neonates, because of the lesions ability to masquerade as one of a variety of much more common abdominal pathologies. Recently we experienced a case of perforated Meckel's diverticulum with mild inflammatory reaction, intestinal adhesion, and small bowel obstruction in a previous healthy 9-day-old neonate. The spontaneous perforation of Meckel's diverticulum in neonate is very rare but serious entity. The course was rapid and progressed to sepsis. So despite its varied presentation, Meckel's diverticulum should be kept in mind as a cause of acute abdomen in neonates.

How the Budget Process Works in the U.S. House Appropriations Committee and Its Implications for the Korean Government

임재영 서울대학교행정대학원 2017 The Korean Journal of Policy Studies Vol.32 No.2

The recent recession and subsequent rescue efforts along with snowballing annual deficits and national debts in the United States have made it urgent for scholars to examine national budget processes across countries. The House Appropriations Committee is a key cog in the annual appropriations process in the United States and understanding how it behaves offers a clue for what to do with central government deficits. I offer a comprehensive review of scholarly contributions on the behavior of House Appropriation Committee since Fenno’s seminal works in 1962 and 1966. Then, I note potential lessons that these studies and U.S experiences can offer for the Korean government.

Analysis of the Prevalence of Taurodont Deciduous Molars in Children

임재영,김익환,송제선 대한소아치과학회 2020 大韓小兒齒科學會誌 Vol.47 No.4

Taurodontism is an anomaly characterized by a long and broad pulpal cavity and consumed apical location of the furcation area. This study aimed to determine the prevalence of taurodontism in deciduous molars based on digital panoramic radiographs of children. The study was performed on a sample of panoramic radiographs taken from 2,473 Korean children who visited the department of pediatric dentistry, Yonsei University Dental Hospital between Nov. 2005 and Mar. 2018. Taurodontism was mainly categorized by Daito’s method. Using panoramic radiographs, taurodontism was also categorized into mesotaurodontism, hypotaurodontism, and hypertaurodontism. Mesotaurodontism was the most prevalent type. A total of 2,473 panoramic radiographs were evaluated. The prevalence of taurodontism was 5.7% in general, 51.5% in the left quadrant, 48.5% in the right quadrant, 6.3% in the maxilla, and 93.7% in the mandible. The distribution of taurodontism stratified by gender showed a higher prevalence in males. This is a comprehensive study on the prevalence of taurodontism in children using the largest sample size to date.
