Since assembled temporary equipment is widely used for construction work that should be carried out before this construction begins, it is essential to secure quality during assembly and prevent safety accidents caused by assembled temporary equipment after installation. However, it was investigated that most construction site managers are not aware of its importance, such as recognizing the quality management of assembled temporary equipment as a task of managing temporary structures that are dismantled after installation for this construction. The quality management work of assembled temporary equipment at the construction site is carried out in different ways for each construction site because there is no formalized procedure and the subject of performing. In addition, it is analyzed that the manager of the general construction company inspects and reflects the parts that need to be inspected without evidence, so transparency is not guaranteed and the result leads to a serious disaster. Therefore, the purpose of this study is to establish a document preparation-oriented system that provides systematic quality evaluation and management procedures for securing the quality of assembled temporary equipment, develops a checklist for quality evaluation and management, and supports history management on the web.

골연골종으로 인한 과두절제 후 하악지 수직 골절단술 및 bone sliding을 통한 즉시 재건: 증례보고

장지영,오제경,차두원,백상흠,Jang, Ji-Young,Oh, Jae-Kyung,Cha, Du-Won,Baek, Sang-Heum 대한악안면성형재건외과학회 2007 Maxillofacial Plastic Reconstructive Surgery Vol.29 No.3

Osteochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and proximal metaphysis of the tibia. However, it occurred rarely on the facial skeleton. The coronoid and condylar processes have been considered to be the most common sites of occurrence for osteochondroma of the facial skeleton. The first treatment of osteochondroma is condylectomy, whereas extirpation was done by excision with condyle salvage. Condylectomy presents decrease of vertical dimension, jaw deviation, malocclusion. So, reconstruction is need. Methods of reconstruction are as follows: no reconstruction, condyloplasty, discectomy, costochondral graft, discplication or coronoidectomy, eminoplasty, alloplastic spacer placement, Le Fort I level maxillary osteotomy, extraoral and intraoral vertical ramus osteotomy. This is a case report of a 28-year old woman who had facial asymmetry, malocclusion and temporomandibular joint pain. We obtained moderate functional and cosmetic results with surgical removal of the osteochondroma by condylectomy and concomitant reconstruction of condyle by vertical ramus osteotomy with sliding technique.

Objectives: This study was designed to evaluate the filtration efficiencies and pressure drops of five commercial cloth masks (4 plate type, 1 cup type) in comparison to the performance of a class 1 disposable respirator (reference respirator). A further objective was to evaluate the effects of the number of layers and wash treatment independently on filtration efficiencies and pressure drops. Methods: Polydisperse NaCl aerosols were generated in an aerosol chamber and their concentrations were measured by an optical particle counter (OPC) in the size range of $0.3{\sim}10{\mu}m$ (five channels). Results: The filtration efficiencies of the five cloth masks and the reference respirator were D: 9.5%, C: 18.5%, E: 23.6%, A: 28.5%, B: 29.7% and R: 91.1%, respectively, and the pressure drops through them were C, D: 0.8 Pa, E: 1.7 Pa, B: 6.4 Pa, A: 42.7 Pa and R: 19.3 Pa, respectively. The filtration efficiencies of the cloth masks and reference respirator were below the class 1 respirator criterion (${\geq}94.0%$) of the Ministry of Employment and Labor (MOEL) and Ministry of Food and Drug Safety (MFDS). The pressure drops satisfied the class 1 respirator criterion (${\leq}70Pa$) of MOEL and MFDS. When the cloth masks were folded into two and four layers, the filtration efficiencies of cloth masks A, B, C, D (plate type) increased 1.7-4.6 times, and 2.3-6.8 times, respectively, compared to the efficiencies of the same products in a single layer. Pressure drops increased as the number of layers was increased. The filtration efficiency of cloth mask E with a liner was 1.3 times higher than that of the same mask without a liner, and the pressure drop was lower in the no-liner configuration. After a single washing, the filtration efficiencies of all the cloth mask products decreased 1.04-4.0 times compared to those of the same products intact. For the cloth masks C and E, their filtration efficiencies were significantly decreased after washing (p<0.05). The pressure drops of all cloth masks were 1.2-2.0 times lower after washing. Conclusions: The filtration efficiencies of the five cloth masks were below 30% and did not improve greatly by increasing the number of layers. After a single washing, their performances decreased. Considering the above and other issues identified with cloth masks, such as poor fit and stretched fibers through use, people should not expect protection against particulate matters from the cloth masks on the market.

The ability of expansionary fiscal policy to boost aggregated demand depends on how private agents react. Under the Ricardian equivalence hypothesis, fiscal policy would not be able to change aggregate demand due to private sector’s offset behavior against changes in public saving. This study aims to analyze how population aging and government debt level affect the empirical validity of the Ricardian equivalence hypothesis across 5-country panel data including Korea and Japan. By using Autoregressive Distributed Lag (ARDL)-bound test, the two variables show statistically significant impact on reinforcing the Ricardian equivalence hypothesis most particularly when government debt level is in excess of a threshold level of 76% of GDP. Accordingly, fiscal expansion measures would not be as effective in this scenario. The empirical analysis also reveals that the speed of the aging variable has a positive and significant effect on private saving. A widening income disparity among the aging population, as it is the case in Korea, would only push the aging population to restrain more from consumption in favor of saving as a measure of protection from future uncertainty, hence, reducing the aggregate demand further.

Purpose : To assess the efficacy of recombinant human granulocyte-macrophage colony-stimulating factor(GM-CSF) in the neutropenia by radiotherapy. Materials and Methods : Eleven patients with various solid tumor were treated with a daily subcutaneous dose of GM-CSF(3-7microgram/kg) for 5days during the radiotherapy. Before and during the course of the study all the patients were monitored by the recording of physical examination, the complete blood count with differential and reticulocyte count and liver function test. Eight patients received prior or concurrent chemotherapy. Results : In 10 patients, the neutrophilic nadir was significantly elevated and the lenght of time that patients had a neutrophil count below 10³/mm³, a threshold known to be critical to acquiring infective complications was shortened following GM-CSF injection. A significant rise (two fold or greater) of neutrophil count was seen in 10 of 11 patients. In most patients, discontinuation of GM-CSF resulted in a prompt return of granulocyte counts toward baseline. However the neutrophil count remained elevated over 10³/mm³ during radiation therapy, and radiotherapy delays were avoided. Other peripheral blood components including monocytes and platelets also increased after GM-CSF treatment. No significant toxicity was encountered with subcutaneous GM-CSF treatment. Conclusion : GM-CSF was well tolerated by subcutaneous route and induced improvement in the neutropenia caused by radiotherapy.

샨딜리야(sandilya) 의 박띠 (Bhakti) 수행

장지영(Jang, Ji-Young) 한국요가학회 2015 요가학연구 Vol.- No.13

샨딜리야의 박띠수뜨라 (이하 SBS) 는 박띠 사상의 철학 적 사유를 통해 해탈을 제시하였다. 이는 서사시대의 유행이 되었던 신에 대한 강렬한 감정과 행위보다는 철학적이고 명상적인 북인도의 슈리 바이슈나바 종파의 전통을 계승한 것으로 보인다. SBS는 박띠 만이 유일하게 해탈을 획득할 수 있다고 말한다. 또한 박 띠의 두 가지 유형들을 통한 해탈을 획득할 수 있는 실제적인 사다나들을 자세히 제시하였다. 즉 낮은 계층의 사람들과 죄를 많은 지은 사람들도 해탈을 획득할 수 있도록 하였다. 마지막으로 샨딜리야는 브라흐만이 유일한 실재라는 샹까라의 의견에는 동의하지만 신의 속성과 인간의 속성은 동일하지 않다는 차별 속의 동일성 (제한적 동일성) 으로 개별적 영혼들은 신의 아주 극소량의 일부일 뿐이기에 동등하기도 동등하지 않기도 하다는 것이다. 이렇듯 샨딜리야는 늘 신에게 사 랑과 애정을 품는 이는 궁극적으로 신과 하나가 될 수 있음을 설명한다. 신을 향한 사랑의 열망이 곧 인간의 본성이 신과 닮아 있음을 아는 것, 그것으로 박띠 만이 신성으로 녹아 들어가는 것을 알게 한다. 이는 세속의 물질적인 삶에서 초월하여 모든 것을 통일성을 인식하는 영적 차원에 이르는 것이라 할 수 있다. 다만 지혜를 통한 갸냐나 욕망이 없는 행위를 통한 방법인 까르마 요가와는 달리 오직 박띠만이 해탈의 길임을 강조한다. 그러므로 박띠 수행은 삶을 충실히 살아가면서 본질이 신성과 닮아 있음을 고찰하는 것이다. 또한 신의 선한 측면들을 발견하고, 그것들을 통해 현실 세계에서의 해탈을 실현시키고자 하는 것, 이것이 바로 샨딜리야에서 배우고자 하는 핵심사상일 것이다. sandilya Bhakti Sutra suggested emancipation through the philosophical speculation of Bhakti thought. It seems that it followed the tradition of the north India’s ś rivai sinavism, which is philosophical and meditative, rather than the intense emotion and act toward god that was famous in the age of epic poetry. SBS says the Bhakti is the only one that can acquire emancipation. They also minutely presented practical sādhanās which can be acquired through Bhakti’s two patterns. Than means, it can leads to emancipation even for people who are in low level or committed numerous sins. For the last, Śānḍilya agrees the Sankara, which means Brahman is the only actual existence, but the attribute of the god and that of human is not equal and equal at the same time because the individual spirits are just the smallest part of the god, and that called Bhedābeda, which means the sameness in difference. Like this, sandilya always explains that the person who has love and af-fection to god cam be with him. The desire of love for god makes people realize that human’s nature is similar to god’s and that leads to know the Bhakti, is the only one to show the way to divinity. That is the transcen-dence from the mundane world’s material life to the spiritual level that can recognize everything’s unity. However, it just emphasize the Bhakti is the only way to emancipation different from the jnana through wisdom or karma yoga, which is a meth-od through acts with no desires.

수막에 발생하는 혈관주위세포종은 경질막에 기초한 드문 종양으로서 국소재발과 함께 신경축이나 신경외장소로 원격전이를 일으킬 수도 있다. 저자들은 수막에 발생한 혈관주위세포종 환자 2예에시 수술 전 방사선치료와 수술 후 방사선치료를 각각 경험하였기에 방사선치료의 역할에 관한 문헌고찰과 함께 보고하고자 한다. 첫 번째 증례는 41 세 남자로 3개월 동안 두통과 우측 반부전마비가 있었다. 1 차 수술과 2차 수술 시 종양은 거의 제거할 수 없었고 수막 혈관주위세포종으로 진단되었다. 수술 전 방사선치료를 좌측 전두두정부의 큰 잔여종앙에 일 회에 1.8 Gy씩 31 회에 걸쳐 총 55.8 Gy를 조사하였다. 방사선치료 후 CT김사상 종양은 현저하게 크기가 줄있고 방사선치료 후 6개월에 시행한 3차 수술 시 잔여 종양의 크기는 2x2 cm 로 완전히 제거되었다. 추적 CT검사상 국소재발의 소견은 없었고 1 차 수술 후 4 년 10개월 동안 원격 전이 없이 생존하고 있다. 두 번째 증례는 45세 여자로 갑작스러운 두통과 시력 장애로 수막종이 의심되어 종앙제거수술을 받았는데 초직 검사상 우측 전두엽에 발생한 혈관주위세포종으로 진단되었으며 시상동을 침습한 소견을 보였으나 완전히 제거되었다 . 국소재발을 줄이기 위해 수술 후 방사선치료가 의뢰되있고 방사선치료는 우측 전두엽 부위에 일 회에 1.8 Gy씩 30 회에 걸쳐 총 54 Gy를 조사하였다. 수술 후 5년 동안 국소 재발이나 원격전이 없이 정상적인 활동을 유지하면서 생존하고 있다. Meningeal hemangiopericytoma (HPC) is an uncommon dura-based tumor and can recur not only locally but also distantly in the neural axis or extraneural sites. We report our experience of radiation therapy, one preoperative and one elective postoperative, in two patients with meningeal HPC and reviewed the role of radiation therapy. A 41-year-old man (Case 1) presented with a 3-month history of headache and right hemiparesis. The mass was nearly unresectable at the first and second operation and diagnosed as meningeal HPC. Preoperative radiation therapy was given with a total dose of 55.8 Gy/31 fractions to the large residual mass of left frontoparietal area. Follow-up computerized tomography (CT) showed marked regression of tumor after radiation therapy. The third operation was performed to remove the residual tumor at 6 months after the radiation therapy and a 2 x 2 cm sized tumor was encountered. The mass was totally removed. The serial follow-up CT showed no evidence of recurrence and he is alive without distant metastasis for 4 years and 10 months after the first operation. A 45-year-old woman (Case 2) presented with suddenly developed headache and visual impairment. Tumor mass occupying right frontal lobe was removed with the preoperative diagnosis of meningioma. It was totally removed with attached sagittal sinusand diagnosed as meningeal HPC. Elective postoperative radiation therapy was performed to reduce local recurrence with a total dose of 54 Gy/30 fractions to the involved area of right frontal lobe. She is alive for 5 years maintaining normal activity without local recurrence and distant metastasis.
