Morgagni 탈장은 횡격막의 전내측 부위의 발달이상으로 열공을 통하여 장관이나 대망과 같은 복강내 구조물이 흉곽내로 빠져나가는 드문 질환으로 알려져 있다. 저자들은 호흡곤란을 주소로 내원하여 방사선학적 검사와 수술로 확진된 1례를 보고한다. Morgagni hernia is improperly located abdominal viscera into the thoracic cavity through the foramen of Morgagni which is a congenital defect at the anterornedial portion of diaphragm. We report a case of Morgagni hernia diagnosed by radiologic examination and operation.

The g Ⅲ gene located in U_L region of Yangsan strain, a field isolate of Aujeszky's disease virus (ADV) in Korea, was cloned into pTZ18R and sequenced. The gⅢ gene consisting of 1,437 nucleotides showed 98% sequence homology with that of Becker strain, a reference strain of ADV. The gene encoding gⅢ of Yangsan strain was placed under the control of Autographa californica nucleopolyhedrosis virus (AcNPV) polyhedrin promoter, and expressed by the derived recombinant baculovirus using Spodoptera frugiperda 9 (Sf9) cells. The expressed gⅢ was a protein with molecular weight of 72kd determined by immunoprecipitation and Western blotting assay using anti-ADV polyclonal antibodies and anti-gⅢ monoclonal antibody. The partially purified gⅢ protein was utilized as antigen in the radial immunodiffusion enzyme assay (RIDEA) to detect to specific antibody against ADV in pig sera. The results indicated that the sensitivity of RIDEA with the recombinant gⅢ protein antigen (98%) was as high as that with the conventional glycoprotein antigen extracted from the ADV infected cells. In addition, the false positive and false nagative reactions in gⅢ RIDEA were significantly reduced than the conventional glycoprotein RIDEA as judged from the results of standard serum neutralization test.

본 연구의 조사 대상은 본 원 에서 요오드화 조영제를 정맥으로 투여받고 CT 검사를 시행한 72,910명과 과거 조영제 과민반응을 겪었던 환자 2,798명을 대상으로 후향적 조사를 시행하였다. 나이, 성별, 과민반응 증상, 조영제 과민반응 기왕력 환자 전처치방법, 사용한 조영제 등을 분석하였다. 조영제 과민반응 발생은 여성과 60대 미만에서 발생 위험이 높고 과거 조영제 과민반응기왕력이 있더라도 적절한 전처치 약물 투여, 조영제 성분 변경을 시행하면 과민반응 발생 위험이 감소한다. 조영제 성분별과민반응 발생률은 Iopromide가 유의하게 과민반응 발생률이 높았고, Iohexol과 Ioversol이 낮은 발생률을 보였다. 조영제 과민반응 재발을 예방하기 위해서는 전처치 약물 단독 사용보다 선행적으로 원인 조영제를 재사용하지 않고 다른 성분의 조영제로 변경하여 사용하는 것이 우선적으로 시행되어야 하고 더불어 전처치 약물 투여와 함께하는 것이 재발을 예방할 수 있을 것이다. The subjects of this study were 2,798 patients who experienced hypersensitivity reaction of contrast media among 72,910 who had had iodinated contrast media administered intravenously and CT examination at our hospital. Retrospective survey was conducted with these subjects. Their age, gender, hypersensitivity reaction symptoms, prepare methods for the patients who had previous hypersensitivity reaction of contrast media, and contrast media administered were analyzed. When it came to the hypersensitivity reaction incidence of contrast media, women and patients aged less than 60 had the high risk of the reaction. Even if patients had previous contrast media hypersensitivity reaction, their hypersensitivity reaction incidence risk was reduced as they had an appropriate premedication drug administered and contrast media were changed. Regarding the hypersensitivity reaction incidence rate by contrast media, Iopromide’s hypersensitivity reaction incidence rate was significantly high, whereas Iohexol and Ioversol had low incidence rates. In order to prevent contrast media hypersensitivity reaction recurrence, it is preferentially necessary to change a contrast media to a different one without reuse of causative contrast media, rather than to use a premedication drug only. Along with that, it is necessary to administer a premedication drug.

Various surgical approaches to the orbits have been used. But the transconjunctival approach, also called the inferior fornix incision, provides adequate access to the orbital floor with esthetic results. Additionally, transconjunctival approach with lateral canthotomy allows more wide surgical field and good access to the orbital area. Generally, preseptal approach is more used rather than postseptal approach in the transconjunctival incision for the prevention of fat herniation during surgery. There are some complications in transconjunctival approaches but these complications can be prevented with careful surgical techniques. We report clinical results in 12 patients who were treated by preseptal transconjunctival incision with lateral canthotomoy for the treatment of orbital trauma. We were satisfied with this technique for reduction and reconstruction of the orbital trauma and we could also observe relatively good esthetic results.

Left sided appendicitis (LSA) has been rarely reported. Almost all of LSA cases are associated with congenital anomalies, such as situs inversus or midgut malrotation. To our certain knowledge, LSA occurring in a patient with an elongated appendix except anomaly has not been previously reported. We present an unusual case of a 73 years old, previously healthy man presented with constipation that had lasted for 4 days, accompanied with leukocytosis and elevated CRP. There was only gas stasis in descending and sigmoid colon on radiologic studies. The patient`s symptom was not improved even with treatment including laxatives for 2 days. Abdominal pelvic computed tomography (CT) scan showed a suspected perforation of diverticulitis and edematous and stenotic change on distal sigmoid colon. Surgical procedure was performed and revealed edematous change of sigmoid colon and 2×7 cm perforated appendicitis with mucocele located between small bowel and sigmoid colon. Appendectomy was performed and there was no malignancy on sigmoidoscopy during surgery. Pathologic evaluation revealed an acute suppurative appendicitis with mucocele. In view of the operative and pathologic findings we thought that the appendix was dilated by mucocele. After the operation the constipation was improved. The patient was discharged on the 5th postoperative day.
클라우드 클러스터에서 가상머신 재배치시간을 단축하기 위한 재매핑 기법

본 논문에서는 클라우드 클러스터에서 가상머신(VM: Virtual Machine)의 재배치시간을 단축할 수 있는 VM 재매핑 기법을 제안한다. 제안하는 기법은 입력으로 주어진 VM 맵으로부터 순차적으로 이주해야 하는 VM들을 찾고 그 중 일부 VM들의 목적지를 교환함으로써 VM 재배치시간을 단축한다. 목적지가 교환될 VM은 이주 완료시간시간과 물리머신들의 가용 자원량을 근거로 하여 선정된다. 그리고 목적지 교환은 VM 재배치 시간이 더 이상 단축될 수 없을 때까지 반복된다. 시뮬레이션을 통하여 VM 맵을 제안한 기법으로 재매핑 했을 때 재매핑 전에 비해 VM 재배치 시간이 최대 42.7% 단축되었음을 확인한다. In this paper, we propose a virtual machine(VM) remapping scheme that reduces VM relocation time on a cloud cluster. The proposed scheme finds VMs that should be migrated in sequence from a given VM map, and exchanges destinations of some VMs among them to reduce the VM relocation time. The VMs, the destinations of which will be exchanged, are chosen based on the amount of physical machine’s available resources and migration completion time. The exchange of destinations is repeated until the VM relocation time cannot be shortened any further. Through a simulation, we show that the proposed scheme reduces VM relocation time by 42.7% in maximum.

With the increase in elderly population rate, interest in development of equipment to aid for the elderly activities has been increased. Since the physical features of repetitive behavior of elderly people standing and sitting can cause the stress on certain parts of the body, The necessity of developing Lift Chair concerning the foregoing problem has been to the fore. In this study, we set the average body size of the elderly aiming to develop non-motorized Lift Chair, developed Non-motorized tilting mechanism based on the Muscle strength change at knee angle, and did a study relatively inexpensive Lift Chair considering esthetic and practicality
