이 논문에서는 한국인 급성심근경색증 환자에 대한 KAMIR 데이터를 기반으로 ST분절상승 심근경색이 처음 발병한 환자의 사망에 영향을 미치는 위험요소들을 찾고, 이를 기반으로 ST분절상승 급성심근경색환자의 1년 이내 사망을 예측하는 모델을 제시한다. 총 22개의 속성 중에서 속성 선택 알고리즘을 적용한 결과 나이, 심장박출계수, 크레아티닌, 고감도 C-반응성 단백질 등 4개의 속성이 선택되었고, 이 속성들을 이용하여 더욱 정확한 예측 모델을 구축할 수 있었다. 제시된 모델을 통해서 고위험군 환자의 위험성을 평가하고 예후를 추정할 수 있을 것으로 기대한다.

A 57-year-old woman scheduled for cochlear implant removal exhibited preoperative electrocardiographic findings of early repolarization (ER). Four episodes of transient ST segment elevations during surgery raised suspicion for vasospastic angina (VA). In the post-anesthetic care unit, the patient complained of chest discomfort and received sublingual nitroglycerin with uncertain effect. The patient refused to proceed with postoperative invasive coronary angiography, resulting in inconclusive diagnosis. Intraoperative circumstances limit the diagnosis of VA, which emphasizes the need for further testing to confirm the diagnosis. When VA is suspected in patients with underlying ER, it is reasonable to consider invasive examination to establish the diagnosis and prevent recurrence of VA. If ST changes are observed during surgery in patients with preoperative ER, careful monitoring is recommended. Due to general anesthesia, the absence of patient symptoms limits the definitive diagnosis of those with suspected VA. Therefore, additional postoperative surveillance is recommended.

Objectives: This study was to investigate the effect of high frequency electro-acupuncture (EA) at $ST_{36}$ acupoint on the Freund's Complete Adjuvant (FCA)-induced arthritis in rats. Methods : Arthritis was induced by intradermal injection of FCA into base of tail. Experimental groups were divided into 4 groups; Normal, Control, $ST_{36}$ and Non-Acupoint (NA). $ST_{36}$ group was treated by 120Hz EA at $ST_{36}$ acupoint. Body weight, paw edema volume and ankle joint thickness were measured after treatment. And we investigated the effects of 120Hz EA via WBC count, segmen neurophil, lymphocyte, PGE2 assay and NADPH-d histochemistry. Results and Conclusions : The mean of body weight and ankle joint thickness of $ST_{36}$ group was increased compared with control group. The mean of paw edema volume, WBC count, segment neutrophil and lymphocyte of were not decreased with control group. The mean of PGE2 concentration ($1,851.00{\pm}160.11$) and NADPH-d positive neurons ($13.12{\pm}1.23$) were changed significantly (p

Video on Demand (VOD) is a multimedia service which allows a remote user to select and then view video at his convenience at any time he wants, which makes the VOD become an important technology for many applications. Numerous periodic VOD broadcasting protocols have been proposed to support a large number of receivers. Broadcasting is an efficient transmission scheme to provide on-demand service for very popular movies. This paper proposes a new broadcasting scheme called Popularity Cushion Staggered Broadcasting (PCSB). The proposed scheme improves the Periodic Broadcasting (PB) protocols in the latest mobile VOD system, which is called MobiVoD system. It also, reduces the maximum waiting time of the mobile node, by partitioning the $1^{st}$ segment of the whole video and storing it in the Local Media Forwarder (LMF) exactly in the Pool of RAM (PoR), and then transmitting them when the mobile nodes miss the $1^{st}$ broadcasted segment. The results show that the PCSB is more efficient and better than the all types of broadcasting and caching techniques in the MobiVoD system. Furthermore, these results exhibits that system performance is stable under high dynamics of the system and the viewer's waiting time are less than the previous system.

한국 연안에서 Paracalanus parvus로 분류되어졌던 종에 대한 분류학적인 재검토를 하였다. 그 결과 한국연안에서 Paracalanus parvus로 분류되어져 왔던 종은 Paracalanus parvus와 Paracalanus indicus, 2종인 것으로 밝혀졌다. 이 두 종의 형태학적 특징 중 가장 뚜렷한 차이는 제$2\~4$유영지였다. Paracalanuss parvus는 제$2\~4$유영지 외지 세번째 마디절 외연 말단부에 거치가 없으며, 제1기절에는 극침이 있다. P. indicus는 제2, 3유영지의 외지 세번째 마디절 외연 말단부에는 거치가 있으나, 제4유영지에는 없다. 또한, 제1기절에 극침이 있다.

Coronary vasospasm is one of the fatal complications that may occur in patients undergoing open heart surgery. To date, however, there are not many cases in this series and no definite pathophysiology has been documented. We experienced a case of coronary artery vasospasm after atrial septal defect (ASD) surgery and then successfully treated it with both transbrachial intraaortic balloon pump and percutaneous cardiopulmonary support. Only several hours after ASD surgery, the patient exhibited the cardiovascular collapse, the ST-segment elevation, followed by ventricular fibrillation and normal coronary angiography findings. It is important to make a differential diagnosis of coronary artery vasospasm in patients presenting with ST-segment elevation who had no notable coronary artery diseases. This case indicates that clinicians should be aware of the possibility that the coronary artery vasospasm may also occur in patients undergoing ASD surgery.

1. Objectives and Methods This study was done to investigate the relationships of Sound parameters between Liver Heat Symptom and Esophagus Symptom of Taeumin using PSSC(Phonetic System of Sasang Constitution) in a sentence. Experimental Participants were 20 Korean adult males including, each 10 Liver Heat Symptom and Esophagus Symptom of Taeumin. 2.

Objective: To compare the spinal enumeration methods that establish the first lumbar vertebra in patients with spinal variants. Materials and Methods: Of the 1446 consecutive patients who had undergone computed tomography of the spine from March 2012 to July 2016, 100 patients (62 men, 38 women; mean age, 47.9 years; age range, 19-88 years) with spinal variants were included. Two radiologists (readers 1 and 2) established the first lumbar vertebra through morphologic analysis of the thoracolumbar junction, and labeled the vertebra by counting in a cranial-to-caudal manner. Inter-observer agreement was established. Additionally, reader 1 detected the 20th vertebra under the assumption that there are 12 thoracic vertebra, and then classified it as a thoracic vertebra, lumbar vertebra, or thoracolumbar transitional vertebra (TLTV), on the basis of morphologic analysis. Results: The first lumbar vertebra, as established by morphologic analysis, was labeled by each reader as the 21st segment in 65.0% of the patients, as the 20th segment in 31.0%, and as the 19th segment in 4.0%. Inter-observer agreement between the two readers in determining the first lumbar vertebra, based on morphologic analysis, was nearly perfect (${\kappa}$ value: 1.00). The 20th vertebra was morphologically classified as a TLTV in 60.0% of the patients, as the first lumbar segment in 31.0%, as the second lumbar segment in 4.0%, and as a thoracic segment in 5.0%. Conclusion: The establishment of the first lumbar vertebra using morphologic characteristics of the thoracolumbar junction in patients with spinal variants was consistent with the morphologic traits of vertebral segmentation.

We report a patient with a ruptured vertebral artery (VA) dissecting aneurysm that was treated by internal trapping of the aneurysm and parent artery using detachable coils with subsequent antegrade recanalization of occluded vertebral artery during the follow-up period. A 38-year-old man was admitted with a ruptured right VA dissecting aneurysm just distal to origin of right posterior inferior cerebellar artery. The dissected segment of the VA was occluded by coil embolization. The 14 months follow-up angiography showed that dissected aneurysm was completely occluded, but the parent artery was recanalized in an antegrade fashion. Based on this unique case, the authors suggest that careful angiographic follow-up of dissecting aneurysm is required, even in patients successfully treated with endovascular occlusion of the affected artery and aneurysm.

Pulmonary systemic arterialization to normal basal lung without sequestration is a rare congenital anomaly. In this rare abnormality, arterialization of the left lower lobe is the most common type. In general, surgical treatments have been performed. Recently, for reducing the complications and risks of surgery, embolization is mainly attempted by using coils. We report a case of 22-year-old male patient with a 10 mm anomalous arterial supply to his normal lung, which is being successfully treated by transcatheter embolization when using the Amplatzer Vascular Plug that has been adapted for the treatment of high-flows and large artery occlusions.
