Avulsion fracture of the calcaneal tuberosity is an uncommon injury. Usually it occurs from indirect trauma, and can be seen in old patients with osteoporosis or in patients with diabetic neuropathy. Follow-up studies showed healing of the fracture in most cases, but skeletal deformity may develop in some cases. Therefore we should take plain X-ray evaluations in diabetic patients with foot and ankle pain, even though there have been no definite trauma history. Four cases of calcaneus avulsion fracture were treated operatively in diabetic patients, and reported.

Stomach cancer is the most diagnosed cancer in Korea. When gastric cancer is detected early, the 5-year survival rate is as high as 90%. Gastroscopy is a very useful method for early diagnosis. But the false negative rate of gastric cancer in the gastroscopy was 4.6~25.8% due to the subjective judgment of the physician. Recently, the image classification performance of the image recognition field has been advanced by the convolutional neural network. Convolutional neural networks perform well when diverse and sufficient amounts of data are supported. However, medical data is not easy to access and it is difficult to gather enough high-quality data that includes expert annotations. So This paper evaluates the efficacy of transfer learning in gastroscopy classification and diagnosis. We obtained 787 endoscopic images of gastric endoscopy at Gil Medical Center, Gachon University. The number of normal images was 200, and the number of abnormal images was 587. The image size was reconstructed and normalized. In the case of the ResNet50 structure, the classification accuracy before and after applying the transfer learning was improved from 0.9 to 0.947, and the AUC was also improved from 0.94 to 0.98. In the case of the InceptionV3 structure, the classification accuracy before and after applying the transfer learning was improved from 0.862 to 0.924, and the AUC was also improved from 0.89 to 0.97. In the case of the VGG16 structure, the classification accuracy before and after applying the transfer learning was improved from 0.87 to 0.938, and the AUC was also improved from 0.89 to 0.98. The difference in the performance of the CNN model before and after transfer learning was statistically significant when confirmed by T-test (p < 0.05). As a result, transfer learning is judged to be an effective method of medical data that is difficult to collect good quality data.

The aim of this study was to evaluate the basic data of Cirsium setidens Nakai fine powder (FPC), which will then be used in the development of functional fooditems. We measures and evaluated the level of pectolinarin content, phenol content, flavonoids content, antioxidants and anti-obesity properties of FPC. Our results from the study showed that the pectolinarin, phenol, and flavonoids contents of FPC measured at 10.95±0.1 5mg/g, 12.92±0.18 mg gallic acid equivalent (GAE)/g and 26.47±0.77 mg rutin equivalent (RE)/g, respectively. The exhibited antioxidant activity of FPC increased significantly depending on the dosage, and additionally. FPC did not show any cytotoxicity up to the dosage level of 500 μg/mL. During adipocyte differentiation, FPC significantly inhibited ROS production and lipid accumulation, compared with the control substance. These results suggest that FPC could be considered a promising resource of natural antioxidants and could serve a variety of health-improving roles in the production of functional food ingredients.

박성진,김선호,Park, Seong-jin,Kim, Sun-ho 사상체질의학회 1999 사상체질의학회지 Vol.11 No.2

1. 연구목적 및 방법 현대에는 과거에 비해 인구수는 증가하고 있으나 경제수준이 높아질수록 출산율은 감소하고 있으며, 대신 자손을 적게 낳고 잘 키우려는 분위기의 확산에 의해 임신중 태교에 관한 관심이 고조되어 있는 실정이다. 그러나 태교에 관한 체계적인 연구는 최근에 들어서야 시도되고 있으며, 사상의학적인 연구는 아직 없는 실정이다. 사상의학에서는 체질에 따라 장국장단(臟局長短), 생리병리적인 특징이 다르므로 치료 및 평상시 섭생법을 달리 하고 있다. 따라서 임신기간에 있어서도 태교는 체질에 따라 달리 이루어져야 건강하고 영리한 아이를 낳을 수 있다고 생각되어 동서양의 문헌에 나타난 태교를 정리하고, 사상의학의 양생법과 비교하여 체질에 따른 태교법을 모색하고자 한다. 2. 연구결과 1. 문헌고찰을 통하여 체질에 따라 태교를 시행한다면 건강하고 영리한 아이를 낳을 수 있다고 생각된다. 2. 고찰에 의하면 모체가 태아의 체질적인 특성형성에 더 큰 영향을 미치므로 모체가 건강해야 건강한 아이를 낳을 수 있다고 생각된다. 3. 태양인산모(太陽人産母)는 노정(怒情)의 비급(偏急)함. 급박지심(急迫之心)을 안정시키고 요척부위(腰脊部位), 즉 중하초부위(中下焦部位)를 보호하는 방법으로 임하는 것이 태교의 요령이라고 할 수 있다. 4. 소양인산모(少陽人産母)는 애정(哀情)의 비급(偏急)함, 구심(懼心)을 안정시키고 방광부위(膀胱部位(골반(骨盤)), 즉 하초(下焦)를 보호하며. 주변온도를 시원하게 하고, 음청(陰淸)한 음식을 섭취하여 보음(補陰)하는 방법으로 태교에 임한다. 5. 태음인산모(太陰人産母)는 약정(藥情)의 비급(偏急)함, 법심(法心)을 안정시키고 뇌추부위, 즉 상초(上焦)를 보호하고, 과식을 피하고 적당한 운동을 함으로써 비만을 예방하는 방법으로 태교에 임한다. 6. 소음인산모(少陰人産母)는 희정(喜情)의 비급(偏急)함. 불안정지심(不安定之心)을 안정시키고, 흉금(胸襟) 배려부위, 즉 중상초부위(中上焦部位)를 보호하며, 주변온도를 따뜻하게 하고, 음식은 기(氣)를 보충시켜주는 따뜻한 음식을 섭취하는 방법으로 태교에 임한다. In Sasang Constitutional Medicine, Sungjung(性情) and physiological characteristics differ depending on one's constitution and in turn, the treatment and regimen must differ for each person. Therefore, by observing that antenatal training during pregnancy should be different depending on one's consitution in order to be more effective, antenatal training was compared to the constitution-specific regimen. The importance of antenatal training in Sasang Constitutional Medicine is based on the fact that the constitution of the parents determines the fetus' constitution and mothers' regimen during pregnancy effects the fetus' health. Since Kyungrakyangtaesul(經絡養胎設) supports weak Dangyuh(黨與), it can be used as a constitution-specific regimen during pregnancy.

Purpose: The purpose of this study was to determine the diurnal blood pressure variation with retinal vein occlusion (RVO) using 24-hour ambulatory blood pressure monitoring (24-hour ABPM). Methods: The subjects in this study visited the department of ophthalmology from May 2012 to December 2012 and were diagnosed with RVO but had no history of hypertension (HTN). Non-dipper was defined as a nocturnal systolic blood pressure (SBP) decrease less than 10%. These values were used to compare the 24-hour ABPM values of the RVO and the control groups. Results: The 24-hour ABPM values, with the exception of the mean nightly SBP, were statistically different whne the RVO group was compared with the control group. The odds of an RVO patient being a non-dipper compared to dipper were 1.81 times greater than in the control. Additionally, the clinical SBP and DBP in the RVO group were not significantly different when the HTN group and the non-HTN group were compared. In contrast, the mean 24-hour SBP and the mean DBP were significantly different in regard to HTN. Conclusions: Patients with RVO have a tendency to maintain high BP throughout the day and also during the night. A patient with non-dipper status can be at risk for RVO, even if the patient does not have HTN. Therefore, 24-hour ABPM is an effective management approach for HTN in addition to strict BP control in patients with RVO.

본 연구는 파괴적 리더십 중에서도 가장 많은 관심을 받아오고 있는 상사의 비인격적 행위가 부하의 이직의도와 조직몰입에 미치는 부정적 결과를 살펴보았다. 또한 상사의 비인격적 행위와 부하의 이직의도 및 조직몰입 간의 관계를 조직의 심리적 계약 위반과 부하의 자기통제력이 조절하는지를 검증 하였다. 이와 함께 연구 결과를 토대로 본 연구의 시사점, 한계 및 향후 방향에 대해 논의하였다. The purpose of this study is to investigate the moderating effects of psychological contract violation and self-control on the relationship between abusive supervision and subordinates' work-related attitudes. Results show that abusive supervision was positively related to subordinates' turnover intention, whereas it was negatively related to their organizational commitment. Futhermore, it is surprising that the moderating effects of psychological contract violation and self-control showed an unexpected pattern. Implication of these results as well as strengths, limitations, and avenues for future research are discussed.

In a retrospective study, we compared the results of 24 cases of Chevron osteotomies with those of 17cases of Wilsons osteotomies in the treatment of hallux valgus. We used FFSS(Fore Foot Scoring System) and radiographic findings. There were no differences between the two operations in terms of pain relief and appearance. All patients in the Chevron and Wilsons osteotomy group had good functional results and were more satisfied with the appearance of the foot. We conclude Wilsons osteotomy is useful method for correction of hallux valgus.

다중 측면 기반의 분산 데이터 할당을 위한 MAPN 모델링

박성진,Park, Seong-Jin 한국정보처리학회 2000 정보처리논문지 Vol.7 No.3

In designing distributed databases, DAP(Data Allocation Problem) is one of the key design issues. Because, however, most of previous researches on DAP have considered only cost aspect, they cannot increase the performance and availability and they are not proper to the system requiring high-availability or real-time processing. Therefore, we need a more formal data allocation model considering multiple aspects. In this paper, we propose the MAPN (Multiple Aspects Petri Net) modeling method for the distributed transaction modeling. The MAPN model, an extended classical petri net, is proposed for the formal modeling considering multiple aspects (cost, performance and availability) concurrently. We demonstrate that we can compose the valid DAP evaluation model considering not only cost but also performance and availability concurrently by using the MAPN structure and MAPN graph.

Objective : Various surgical approaches have been implemented to fulfill the ideal goals of treatment for cervical spondylotic lesions. Conventional approaches are represented by anterior approach with or without fusion and posterior approach. The authors has applied newly developed anterior cervical microforaminotomy for these lesions on minimally invasive basis. Materials and Method : Twenty-one patients, with cervical HIVD, or stenosis, or both, underwent anterior cervical microforaminotomy between March, 1998 and April, 1999. Fifteen patients underwent unilateral decompression, and 6 bilateral decompression via unilateral foraminotomy. Operation of one level was performed in 16 patients, 2 levels in 4 patients, and 3 in 1 patient. The foraminotomy was accomplished by resecting the uncovertebral joint. Through this hole, compressed nerve root was decompressed by removing the spondylotic spur or disc fragment, and diagonal removing of posterior osteophyte from foraminotomy site to begining of contralateral nerve root made spinal cord decompression. Results : The outcome was excellent in 17 patients(81%) and good in 4 patients(19%) based on Odom's criteria. No complication was encounterd, and average post-operation hospital stay was 3.7 days. Conclusions : These results indicate that anterior cervical microforaminotomy provide adequate neural decompression, minimum postoperative discomfort and fast recovery.
