Objectives: The purpose of this study is to investigate the effect of ultrasound therapy on left knee pain and instability diagnosed with Baker's cyst in a 25-year-old male patient. Methods: Patient was treated with Radio frequency ablation treatment on left knee from Naeseulan (EX-LE4) to Wijoong (BL40). The effect of radio frequency ablation was assessed by Visual Analog Scale (VAS), Western Ontario and McMaster Universities (WOMAC) and Euro Qol-5 Dimension Index (EQ-5D Index). The treatment was executed one time a day everyday form May 28th to June 1st of 2020. Patient was observed from May 26th to June 1st. Results: After five sessions of radio frequency ablation, VAS of left posterior knee pain was improved while no improvement was discovered at left medial knee. In Korean WOMAC scale, only subscale of weight bearing and walking around plain were improved. EQ-5D did not show any improvement. Conclusion: The results suggest that radio frequency ablation treatment can be a valuable option in treating knee pain and daily living function. Further study seems to be needed based on long-term intervention.

한아람(Aram Han),정봉재(Bongjae Jung),박지군(Jikoon Park),강상식(Sangsik Kang),최일홍(Ilhong Choi),정형진(Hyungjin Jung),노시철(Sicheol Noh) 한국방사선학회 2014 한국방사선학회 학술대회 논문집 Vol.2014 No.춘계

본 연구에서는 뇌혈관 조영CT(CTA)에 있어 320-MDCT의 Volume scan과 64-MDCT의 Helical scan의 영상과 방사선량을 비교하여 320-MDCT의 유용성을 평가하였다. 동일 증상으로 두 가지 장비를 이용하여 뇌혈관 CTA를 시행한 환자 21명의 검사 결과를 이용하여 평가하였다. 비교 결과 320-MDCT의 영상이 64-MDCT영상에 비해 대조도 및 선예도가 높고 혈관 부근에서 Noise도 적은 것을 확인 할 수 있었으며, 유효선량도 64-MDCT 보다320-MDCT가 약 15% 정도 낮게 측정되었다. In this study, the image quality and effective dose were analysed and compared of 320-MDCT Volume scan and 64-MDCT Helical scan in cerebrovascular CT angiography. Using these comparison, we evaluated the usefulness of 320-MDCT. We analysed the 21 patient’s cerebrovascular CTA results who examined using both devices to the same symptoms. With the results of comparison, the images of 320-MDCT represented higher contrast and sharpness and less noise in the vicinity of blood vessels than the images of 64-MDCT. Moreover, the effective dose of 320-MDCT was about 15% lower than 64-MDCT.

한아람 ( Aram Han ) 아시아문화학술원 2018 인문사회 21 Vol.9 No.4

본 연구는 국내 반려동물 산업에 대한 관심이 증가되는 시점에서 대전과 청주지역에 거주하는 반려동물을 소유한 성인을 대상으로 반려동물에 대한 태도가 성인의 주관적 행복감에 미치는 영향을 규명하는데 있다. 연구결과는 다음과 같다. 첫째, 반려동물에 대한 태도는 성인의 성별, 연령별, 반려동물의 소유 수, 소유 기간에 따라 유의한 차이가 있음을 확인할 수 있었다. 둘째, 성인의 주관적 행복감은 성별, 연령별, 반려동물의 소유 기간에 따라 유의한 차이가 있었다. 특히, 10년 이상의 반려동물을 소유한 집단에서 주관적 행복감이 가장 낮은 것을 확인할 수 있었다. 셋째, 반려동물에 대한 태도는 성인의 주관적 행복감 전체 변량의 9% 정도 유의한 영향을 주고 있음을 확인할 수 있었다. 또한, 성인의 주관적 행복감에 반려동물 소유에 대한 즐거움이 가장 큰 긍정적인 영향을 주었고, 반면에 가정에서의 반려동물 사육은 부정적인 영향을 주는 것을 확인할 수 있었다. 본 연구결과는 반려동물과의 상호작용은 성인의 반려동물에 대한 태도와 주관적 행복감에 대체로 긍정적인 영향을 미치지만, 부정적인 영향을 주는 요인에 대한 대책을 통해 반려동물을 소유한 성인의 주관적 행복감을 향상시키기 위한 노력이 필요함을 시사한다. With the increased interest in the domestic companion animal industry, the objective of this study is to examine the effects of attitude to companion animals on the adults’ subjective well-being, targeting the adults with companion animals in Daejeon and Cheongju region. The results of this study are as follows. First, The attitude to companion animals showed significant differences in accordance with sex, age, the number of companion animal, and the period of possession. Second, the adults’ subjective well-being showed significant differences in accordance with sex, age, and the period of possession. Especially, the group of possessing companion animals for ten years or up showed the lowest subjective well-being. Third, the attitude to companion animals had significant effects on the 9% of the whole subjective well-being variable. Also, the pleasure of possessing companion animals had the most positive effects on the adults’ subjective well-being while the breeding of companion animals at home had negative effects on it. The results of this study imply that the interaction with companion animals would have mostly positive effects on the adults’ attitude to companion animals and subjective well-being, and it would be still needed to put efforts to improve the subjective well-being of adults who possess companion animals by establishing the measures for the factors having negative effects.

최근 스마트공장 질적 고도화의 일환으로 제조 생태계에 AI·빅데이터 기술적용에 대한 관심이 고조되고 있다. 그러나 기존 제조기술 트렌드 연구는 스마트공장 구축을 위한 자동화·로봇화에 집중되어 제조 AI·빅데이터 중심의 제조기술 트렌드 연구 및 활용은 미비한 실정이다. 본 연구는 제조업에 적용되는 AI·빅데이터 기술에 대한 최근 6년 동안의 주요 이슈 및 트렌드를 분석하여 제조기업의 AI·빅데이터 기술도입의 방향성을 제시하고자 한다. 분석결과의 적시성과 정확도를 증대하기 위해 특허, 논문, 뉴스, 박람회, 인공지능 중소벤처 제조플랫폼(KAMP) 콘텐츠를 분석 데이터로 통합화하였다. 그리고 수집 데이터의 정제로 Python 3.6과 텍스트 마이닝 및 소셜네트워크분석은 KrKwic 2.0, UCINET 6.721을 활용하였다. 분석 결과, 시간의 흐름에 따라 제조 특화 AI, 딥러닝, 알고리즘 키워드의 연결중심성이 높아지는 것으로 나타났으며 이를 구현하기 위해 고성능 컴퓨팅 기술을 포함한 다수의 제조AI 기술군집이 형성되었다. 제조현장의 AI 적용목적에 따라 보다 다양하고 최적화된 제조 특화 AI 알고리즘 및 제조 빅데이터 융·복합기술의 중요도가 증가하고 있음을 관찰할 수 있었다. Recently, there has been a surge of interest in manufacturing AI and big data technology application. Since current manufacturing technology trend research is focused on automation and robotization for the construction of smart factories, study and utilization of manufacturing technology trends centered on manufacturing AI and big data are insufficient. Therefore, this study examines major issues and trends in AI·big data technologies applied to the manufacturing industry over the last six years. To reflect the timeliness and accuracy of analysis results, patents, theses, news, fairs, and Korea AI Manufacturing Platform(KAMP) contents are integrated into analysis data, and data refinement is performed using Python 3.6, text mining, and social network analysis. KrKwic 2.0 and UCINET 6.721 were utilized for this purpose. It was discovered that the degree centrality of manufacturing AI keywords rose with time, prompting the formation of a number of manufacturing AI technology clusters. The significance of more diverse AI algorithms specialized in manufacturing and high-performance infra resources increases depending on the aim of AI application in the manufacturing site.

Objectives: This study investigated the clinical characteristics of functional dyspepsia (FD) patients with food retention (FR) in regard to the parameters of cutaneous electrogastrography (EGG), Ryodoraku, and heart rate variability (HRV). Methods: This study reviewed the clinical records of 33 FD patients with FR who filled out the FR Questionnaire for FD (FRQ-FD) and underwent EGG for six months from March 1st, 2021. We summarized the clinical characteristics of FD patients with FR and analyzed the correlation between FRQ-FD score and parameters of EGG, Ryodoraku, and HRV. Results: FRQ-FD scores had a positive correlation with percentage of postprandial bradygastria and negative correlation with power ratio, detected on Channel 2, 3 of EGG. The total average (TA) Ryodoraku score was lower, and the high frequency density (HF) of HRV was higher than the normal value. Conclusions: The results of this study suggest that clinicians can use EGG, Ryodoraku, and HRV to increase the accuracy of diagnosing FR in FD patients.

Nausea and vomiting disappeared, stool condition improved, and weight increased (from 30 kg to 33 kg) following treatment. Nausea and vomiting disappeared, stool condition improved, and weight increased (from 30 kg to 33 kg) following treatment. Conclusion: It would be worth examining the long-term effectiveness of Korean medical treatment for pediatric Crohn's disease.

Purpose: Functional dyspepsia (FD) is a chronic syndrome accompanied by repetitive digestive symptoms that appear in the upper gastrointestinal tract and are not caused by specific diseases. Psychological symptoms like anxiety, depression, insomnia, and somatization are frequently observed in FD. The purpose of this study was to review the effect of herbal medicine on the psychological symptoms that accompany FD. Methods: Database search (PubMed, EMBASE, KISS, Kmbase, KoreanMed, NDSL, OASIS, CNKI) was performed on February 24, 2021; a total of 1825 studies were searched. After the screening, 22 studies were included. Results: The studies were assessed by Cochrane RoB 2 and sorted into a table according to psychological symptoms. Meta-analysis was performed to estimate the effect of herbal medicine. Twenty of the twenty-two studies reported that herbal medicine was significantly more effective than the control group. Only three of the studies did not have a high risk of bias. Conclusion: Herbal medicine was significantly effective with or without Western medicine and had fewer adverse effects. Severe adverse effect was not reported. Psychological symptoms in FD affect onset and duration of FD, and some FD patients want to be treated for their anxiety before other symptoms. Reliable information about treatment for the psychological symptoms of FD is lacking. We reviewed the effect of herbal medicine treatment in this study, the results of which could be selected for primary or secondary treatment for FD.
