Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

Background and Objectives : Several speech manifestation are observed in temporal lobe epilepsy(TLE). We studied the frequency of ictal speech manifestations and their localizing and lateralizing value in TLE. Methods : We reviewed 379 seizures recorded on videotape in 135 patients who underwent temporal lobectomy for intractable TLE. We divided patients into group A(n=75) who became seizures free after surgery, and group B(n=60) who were only slightly benefited or unchanged after surgery. Speech manifestations were classified as normal speech, vocalization, or abnormal speech. Abnormal speech was subdivided into speech arrest, dysarthria, dysphasia, or nonidentifiable speech. Results : Speech manifestations occurred in 70(18.5%) seizures of 28 patients. Forty eight seizures of 20 patients were observed in group A, and 22 seizures of 8 patients were observed in group B. In group A, 25 seizures of 11 patients were originating from dominant hemisphere, 23 seizures of 9 patients from nondominant hemisphere. In group B, 13 seizures of 5 patients were originating from dominant hemisphere, and 9 seizures in Lt. side and 6 seizures in Rt. side, respectively) of group A(P>0.05), and eleven seizures of 4 patients(8 seizures from Lt. side and 3 seizure from Rt. side) in group B(P>0.05). Normal speech was observed only seizures from Rt. side in both groups(3 seizures in 1 patient, each group). Dysphasia occurred only in seizures originating from Lt. side. Nonidentifiable speech occurred in 22 seizures of 9 patients(11 seizures from each side) in group A(P<0.01), and 3 seizures of 1 patient occurred only from Lt. side in group B. Conclusion : Ictal speech manifestations were not uncommon(18.5%). All kinds of ictal speech manifestations except normal speech have no reliable lateralizing and localizing value in TLE. Normal speech could be a good indicator of seizure originating from nondominant hemisphere.

This paper intends to explain ideology and political culture, and to know ideology and political culture in relation to the political system, and then to study how they are related. Ideology is the idea system to maintain a certain society and political orientation of people in a society. Liberal democratic ideology produces the political culture consistent with democratic ideology and also the political culture characterized by liberal democratic ideology influences to make democratic ideology. And communist political culture influences to have communist ideology consistent with communist political culture and communist ideology influences to make political culture consistent with communist ideology. In conclusion, political culture and ideology are independent and influence each other closely.

This paper proposes a time series prediction method for the nonllinear system using the fuzzy system and the evolutionay strategy and the genetic algorithm. At first, we obtain the optimal fuzzy membership function using the evolutionary strategy or genetic algorithm. With the optimal fuzzy rules and its input differences, a better time prediction series system may be obtained. We obtain a good result for the time prediction of the short term electric load. In addition we implement the graphic user interface for the proposed algorithms.

유암종은 전신에 퍼져 잇는 장크롬친화성 세포에서 기원하는데 위의 유암종은 비교적 드문 질환으로 모든 유암종의 1.9~2.2%에 해당하며 위에 발생하는 종양의 1% 미만에서 보고되고 있다. 유암종은 일반적으로 증상이 비특이적이고 면역조직화학검사에 의해서 진단되기 때문에 과거에는 드물게 발견되었으나 최근 내시경 기기 및 술기의 발전과 검사 빈도의 증가 및 면역조직화학검사의 발달로 진단율이 증가 추세에 있으며, 드물지만 유암종에서 선암과 공존하는 예들이 보고되고 있다. 저자들은 심와부 동통을 주소로 내원한 70세 남자 환자의 상부위장관내시경 검사에서 위체상부의 대만곡에서 0.4×0.4 cm 크기의 중간 함몰을 가진 Yamada 1형의 용종과 함께 전정부의 전벽에서 0.8×0.5 cm 크기의 융기된 점막 소견을 보여 조직학적으로 각각 위유암종 및 위선종임을 확진한 후 내시경적 용종 절제술로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body. These tumors are composed of variable numbers of cells that contain endocrine granules in their cytoplasm, which can be identified by immunohistochemistry and electron microscopy. Gastric carcinoid tumors are relatively rare tumor, the reported incidence being 1.9~2.2% of all carcinoid tumors and less than 1% of all gastric tumors. Sometimes, composite carcinoid tumors and adenocarcinoma is reported. We experienced a case of the coincidence of carcinoid tumor and adenoma at the other site of the stomach in a 70 year old male patient. Gastrofiberscope showed 0.4×0.4 cm sized Yamada type I polyp with central depression on the greater curvature of the proximal body and 0.8×0.5 cm sized focal slightly elevated mucosa on the anterior wall of the antrum. The endoscopic biopsy specimens revealed carcinoid tumor and tubular adenoma with moderate atypism, respectively. The carcinoid tumor and adenoma were removed by endoscopic polypectomy. According to the follow-up gastrofiberoscopy after 7 month later, both lesions were nearly normal mucosa except whitish atrophic change after polypectomy.

Welding is on the important situation in the connect methods of metals. The interrelationships of nonstress relief annealing, stress relief annealing, hardness value of welding area in the full annealing state, impact value, microstructure, and fracture were studied with the welded mild steel, therefore I got the followingresults. In the respect of impact value and hardness value, the mechanical characteristics of welding area were as good as those of base metal. Especially, as stress relief annealing not only decreased the high hardness of welding area but also increased the impact value of heat area, the negative effects of local heating were reduced and the whole impact value was improved effectively. The smaller the crystilline structure and the area rate of brittleness fracture, the more the hardness value and impact value, and the crystals of welding area that was heattreated with stress relief annealing and full annealing were still smaller than those of base metal. However, I can conclude from my experiment that it is difficult to use the full annealed materials as a welding structure, because the crystals of full annealed materials increase in size and the mechanical characteristics get worse.

자동차의 air-bag 장치에 실용될 수 있는 압저항형 단결정 실리콘 가속도센서 칩을 개발하기 위하여 결정 실리콘 미세구조의 제조방법을 확립하고, 단위공정의 검증을 통하여 일괄공정에 의한 PROTO-TYPE 칩을 만드는 기술을 연구하였다. 단결정 실리콘 미세구조는 선택확산법을 이용하여 정확히 선택된 영역에만 air-gap을 형성하여 미세구조의 측면식각을 방지하는 선택확산법에 의한 실리콘 마이크로머시닝 기술로 제조하였다. 일괄공정을 위한 단위공정확립을 위하여 PROTY-TYPE 8빔 브릿지형 가속도 센서를 제조하였다. 제조된 칩의 가속도에 따른 출력전압은 선형성을 나타내고 있으며, 감도는 약 50 ㎶/V·g로 나타났다. 이 감도는 50G용 가속도센서의 사양을 만족하지 못했다. 이는 공정에 의한 문제라기 보다는 가속도센서의 시뮬레이션에 의해 설계한 구조가 이미 원하는 감도에 못 미친다는 것으로 생각된다. 따라서 2차 공정으로 제조될 가속도센서의 파라미터를 SuperSAP 유한요소 패키지를 이용하여 실리콘 미세구조부의 파라미터에 따른 특성을 시뮬레이션하였다. 설계된 50G용 가속도센서의 mass Pad의 반경 및 빔 길이, 빔 폭, 빔 두께, 그리고 mass의 각 파라미터 값은 700 ㎛, 120 ㎛, 5 ㎛, 1.0 ㎎ 이었다. 반도체 공정기술, 관성질량 제조법 및 선택확산을 이용한 마이크로머시닝을 사용하여 일괄공정으로 8빔 브린지형 가속도센서를 제조하였다. We researched the establishment of the silicon microstructure fabrication technique to develop a piezoresistive type silicon acceleration sensor chip and the technique to make a proto-type chip by the verification of the unit-process. Silicon microstructure is fabricated silicon micro-machining by selective diffusion method. This method prevent a side-etching of microstructure because selective diffused region is only formed an air-gap. We fabricated a proto-type 8-beam bridge-type acceleration sensor to establish the unit-process for the batch-process. The output voltage of the chip represented linearity with acceleration, and the sensitivity was about 50 ㎶/V·g. But this sensitivity dosen't satisfy the requirements of a practical acceleration sensor. The cause of this result is assumed not process problem, but the structure designed by simulation isn't suitable already. Threfore, the characteristics of parameters of the acceleration sensor that will be fabricated by 2nd-process is simulated by SuperSAP finite-element package. The determined parameter values of beam length, beam width, beam thickness, mass, and mass radius are 120 ㎛, 5 ㎛, 1.0 ㎎, and 700 ㎛, respectively. We fabricated 8-beam bridge-type acceleration sensor by batch-process using a semiconductor process technique, proof-mass fabrication method, and micromachinig using selective diffusion.
