이 연구의 목적은 규칙적인 12주간 방과 후 순환운동을 통하여 지적장애 학생의 자기결정력과 운동수행능력의 발달가능성을 규명하고, 학교나 가정, 사회생활 속에서 성숙한 인격적 개체로서 존중받으며, 사회구성원으로서 역할을 성공적으로 수행해 나갈 수 있도록 하는데 있다. 연구대상은 A시에 거주하면서 B특수학교에 재학 중인 남자 경도 지적장애 학생 총 20명으로 참여집단 10명과 통제집단 10명을 단순무선 표본추출(simple random sampling)로 할당하여 순환운동에 참여하였다. 측정도구로 자기결정력은 학생을 자기결정력 평가척도(이영미, 2006), 교사용 자기결정력 평가척도(방명애, 2001) 질문지를 사용하였으며, 운동수행능력 검사도구는 김정권, 권기덕, 최영하(1987_에 의해서 한국에서도 표준화된 오세레츠키 운동능력 검사도구를 사용하였다. 측정된 자료는 PASW Version 18.0K 통계프로그램을 이용하여 집단별 자기결정력과 운동수행능력의 평균과 표준편차를 산출하였고, 측정 시기(사전ㆍ6주경과 후ㆍ사후)에 따른 변화를 반복측정에 의한 변량분석을 사용하였으며, 통계적 유의 수준은 .05로 설정하였다. 방과 후 운동 참여를 통한 자기결정력의 변화에서는 참여집단이 통제집단과 비교하여 자신에 대한 인식, 자신의 가치 존중, 계획의 변화, 실행의 변화, 결과에 대한 평가 및 총점의 변화 비교에서 평균점수가 2배 이상 증가하였으며, 참여집단의 변화는 6주보다 12주가 경과한 후 더 많은 증가 현상이 나타났다. 또한 운동수행능력의 변화에서는 참여집단이 통제집단에 비해 정적, 손동작, 일반동작의 협응 및 운동속도, 동시적 자발동작, 단일동작 수행능력 및 운동연령에 증가하였으며, 참여집단의 변화는 6주보다 12주가 경과한 후 증가 현상이 나타났다. 이상의 결과를 종합해 볼 때, 순환운동을 하면 자기결정력과 운동수행능력은 증가가 되는데, 이러한 긍정적인 결과를 가져오기 위해서는 12주 이상의 운동을 실시하였을 때 긍정적인 효과가 나타난다는 것을 알 수 있었다. The purpose of this research was to investigate the effect of the 12-weeks after-school rotating exercise program on self-determination and sports performance abilities of students with mild intellectual disabilities. Participants were 20 students with mild intellectual disabilities in a special-education school. Through simple random sampling, 10 students were placed in an experimental group and they were involved in the after-school rotating exercise program. The other 10 students were placed in a control group. The instruments used in this study were Korean-version of Self-Determination Student Scale (Lee, Youngmi, 2006), Self-Determination Teacher Perception Scale (Bang, MyungAe, 2001), and Standardized Oseresky Sports Ability Test (Kim, Jungkwon, Kwon, Kiduk, & Choi, Youngha, 1987). The data were analyzed using the two-way ANOVA with repeated measures in order to measure changes across time (before intervention after 6 weeks after intervention). The results of this study presented that students in the experimental group presented improved self-determination and sports performance abilities than those in a control group. These changes were more prominent after 12-weeks of the after-school rotating exercise program participation than after 6-weeks participation.

In this study, we propose a new system for constructing parallel corpora for sign languages, which are generally under-resourced in comparison to spoken languages. In order to achieve scalability and accessibility regarding data collection and corpus construction, our system utilizes deep learning-based techniques and predicts depth information to perform pose estimation on hand information obtainable from video recordings by a single RGB camera. These estimated poses are then transcribed into expressions in SignWriting. We evaluate the accuracy of hand tracking and hand pose estimation modules of our system quantitatively, using the American Sign Language Image Dataset and the American Sign Language Lexicon Video Dataset. The evaluation results show that our transcription system has a high potential to be successfully employed in constructing a sizable sign language corpus using various types of video resources.

The nutritional support of acutely ill patients is very important and early enteral nutrition is recommended. Feeding via the nasogastric route is used widely for its ease of access if the patient cannot maintain volitional food intake. If the position of the tip or side holes of the nasogastric tube (NGT) is above the gastroesophageal junction, there is the possibility of retention and solidification of the administered enteral feeding formula in the esophagus. Therefore, the tip of the NGT should be checked carefully; a chest radiograph to confirm its position can be considered, especially in patients with a higher risk of aspiration and gastroesophageal reflux. In addition, careful consideration of the risk factors that can trigger esophageal obstruction is required when feeding patients in the intensive care unit. This paper describes two unusual cases of esophageal obstruction caused by the solidification of residue of an enteral feeding formula.

목적 : 토양에서 암모니아 배출에 미치는 영향에 관한 문헌 고찰을 통하여 주요 요인들을 파악하고, 암모니아 배출감소를 위한 대책을 설립한다. 방법 : 농업, 암모니아, 미세먼지 등의 키워드를 활용하여 학술검색을 수행하였으며, 수집된 문헌에 대하여 토양의 특성이 암모니아 배출에 미치는 영향에 대해서 각 항목별로 정리하였다. 결과 및 토의 : 암모니아의 대기 중으로 배출은 잠재적으로 농업인의 경제적 수익을 감소시킬 뿐만 아니라 초미세먼지(PM2.5) 형성에 전구물질로 작용하여 대기 환경에 부정적인 영향을 미칠 수 있다. 국내 암모니아 주요 배출원 중에서 농업이 차지하는 비중은 78% 정도로 보고되고 있다. 본 연구에서는 토양에서 암모니아 배출은 암모니아 비료의 종류, 토양수분, pH, 온도, 양이온교환용량, 유기물, 토성에 영향을 받는다. 토양수분의 증가는 암모니아 배출량을 증가시킨다. 토양 pH가 증가함에 따라서 암모니아 배출량이 증가하는데 특히 7.5 이상에서 크게 증가한다. 토양 온도의 증가는 요소의 가수분해 속도와 암모니아 가스로 전환하는 속도를 증가시켜 암모니아 배출이 증가한다. 양이온교환용량이 큰 토양은 암모늄을 흡착시켜서 암모니아 배출을 감소시킨다. 점토 함량과 토양 유기물 함량이 높은 토양은 토양 pH 변화에 완충성이 커서 암모니아 배출을 감소시킨다. 결론 : 토양에서 암모니아 배출에 대한 기작 및 원인에 대한 이해를 바탕으로 최적의 토양 관리 및 환경 관리를 통해서 대기 중으로의 암모니아 배출을 저감 할 수 있다. Objectives : Major factors affecting ammonia emission from the soil and strategies to reduce ammonia emission were investigated through literature surveys. Methods : An academic search was conducted using keywords such as agriculture, ammonia, and fine dust, and the effects of soil characteristics on ammonia emission were summarized for each factor. Results and Discussion : Emissions of ammonia into the atmosphere can reduce economic returns for a farmer and negatively impact the atmospheric environment by acting as a precursor to PM2.5 formations. It is reported that agriculture accounts for 78% of the total ammonia emission sources in Korea. Ammonia emission from the soil is affected by the type of ammonia fertilizer, soil moisture, pH, temperature, cation exchange capacity, organic matter, and soil texture. An increase in soil moisture increases ammonia emissions. As soil pH increases, ammonia emissions increase, noticeably above 7.5. An increase in soil temperature increases the rate of hydrolysis of urea and the rate of conversion to ammonia gas, resulting in increased ammonia emissions. Soils with high cation exchange capacity adsorb ammonium to reduce ammonia emissions. Soils with a high clay content and soil organic matter content are more buffered to changes in soil pH, reducing ammonia emissions. Conclusion : Based on understanding the mechanisms and causes of ammonia emission from the soil, it is possible to establish soil and environmental management to reduce ammonia emissions into the atmosphere.

Kim, Jung-Sun,Lee, Hancheol,Suh, Yongsung,Pak, Hui-Nam,Hong, Geu-Ru,Shim, Chi Young,Yu, Cheol-Woong,Lee, Hyun-Jong,Kang, Woong-Chol,Shin, Eun-Seok UNKNOWN 2016 CIRCULATION JOURNAL Vol.80 No.5

<P>Background: The aim of this study was to evaluate clinical outcome after left atrial appendage (LAA) occlusion in real clinical practice and compare between Amplatzer cardiac plug (ACP) and Watchman. Methods and Results: From October 2010 to February 2015, 96 successful LAA occlusion procedures were performed using either ACP (n=50) or Watchman device (n=46) in non-valvular atrial fibrillation (AF) patients (59 male; age, 65.1 +/- 9.4 years; CHADS2, 2.5 +/- 1.2; CHA(2)DS(2)-VASC, 3.9 +/- 1.6; HAS-BLED, 2.7 +/- 1.3). The procedure success rate was 96.8%. There were serious complications in 4 patients (4.1%; 2 cardiac tamponade, 1 device embolization, and 1 major bleed). The anticoagulation cessation rate after 6 weeks was 92.7%. During mean 21.9-month follow-up, the incidence of death, stroke, systemic embolization and major bleeding was 5.2%, 4.2%, 0% and 1.0%, respectively. On transesophageal echocardiography of 93 patients within 6 months after the procedure, 24 residual leaks were observed (25.8%; 2 mild, 18 moderate, and 4 major). Clinical outcome was similar for the 2 devices, but peridevice leakage was more frequent with the Watchman than the ACP. Conclusions: LAA occlusion was feasible in non-valvular AF patients with high risk of stroke and hemorrhage. The ACP and Watchman devices were similar in terms of procedural and clinical outcomes.</P>

Diagnostic and Therapeutic Laparoscopy for Abdominal Trauma: A Single Surgeon’s Experience at a Level I Trauma Center

( Hancheol Jo ),( Dong Hun Kim ) 대한외상학회 2021 大韓外傷學會誌 Vol.34 No.4

Purpose: Laparoscopy has various advantages over laparotomy in terms of postoperative recovery. The number of surgeons using laparoscopy as a diagnostic and therapeutic tool in abdominal trauma patients is increasing, whereas open conversion is becoming less common. This report summarizes a single surgeon’s experience of laparoscopy at a level I trauma center and evaluates the feasibility of laparoscopy as a diagnostic and therapeutic tool for abdominal trauma patients. Methods: In total, 30 abdominal trauma patients underwent laparoscopy by a single surgeon from October 2014 to May 2020. The purpose of laparoscopy was categorized as diagnostic or therapeutic. Patients were classified into three groups by type of surgery: total laparoscopic surgery (TLS), laparoscopy-assisted surgery (LAS), or open conversion (OC). Univariate analysis was performed to determine the advantages and disadvantages. Results: The mechanism of injury was blunt in 19 (63.3%) and penetrating in 11 patients (36.7%). Eleven (36.7%) and 19 patients (63.3%) underwent diagnostic and therapeutic laparoscopy, respectively. The hospital stay was shorter for patients who underwent diagnostic laparoscopy than for those who underwent therapeutic laparoscopy (5.0 days vs. 13.0 days), but no other surgical outcomes differed between the groups. TLS, LAS, and OC were performed in 12 (52.2%), eight (34.8%), and three patients (13.0%), respectively. There was no significant difference in morbidity and mortality among the three groups. Conclusions: Laparoscopic surgery for selected cases of abdominal trauma may be feasible and safe as a diagnostic and therapeutic tool in hemodynamically stable patients due to the low OC rate and the absence of fatal morbidity and mortality.
