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.

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.

Purpose: Nowadays, non-operative management increases in patients with blunt splenic injury due to development of diagnostic and interventional technique. The purpose of this study is to evaluate the management in patients with blunt splenic injury and effect of clinical state such as shock on the choice of management. Methods: From April 2007 to July 2013, we retrospectively reviewed the medical charts of fifty patients who had splenic injury after blunt trauma. The demographic characteristics, American Association for the Surgery of Trauma (AAST) grade of splenic injury, management method (emergency operation, angiographic embolization or observation) and clinical outcome were analyzed. Results: The mean age was 41.5±21.4 years and male was 44(88%). Twenty patients(40%) were in shock condition initially and five patients(10%) underwent emergency operation due to hemodynamic instability. Emergency angiographic embolization was performed in 20 patients(40%) and 25 patients were managed conservatively. When patients were divided into shock group (SG) and non-shock group (NSG), Patients in SG had significantly higher serum lactate level and base deficit than NSG (lactate; 4.5±3.4 mmol/L, base deficit; 5.8± 4.4 mmol/L vs 1.9±1.4 mmol/L, 2.8±2.5 mmol/L, p=0.007, p=0.013). There was no significant difference of AAST grade and contrast blush rate in abdomen CT between two groups. Among 45 patients with non-operative management, four patients(8.9%) got delayed angiographic embolization and 3 patient died from companied organ injury. Conclusion: Non-operative management can be acceptable management option in patients with splenic blunt trauma under intensive hemodynamic monitoring.

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.

장지영(Jang Ji young),오윤정(Oh Yoon jeong),최경희(Choi Kyung hee) 학습자중심교과교육학회 2010 학습자중심교과교육연구 Vol.10 No.3

본 연구에서는 중등 과학 교육과정 개정(제7차 교육과정, 2007 개정 교육과정, 2009 개정 교육과정)에 따라 첨단과학기술분야와 관련된 내용이 어떻게 다루어지고 있는지 살펴보기 위하여 6 첨단과학기술분야(6T; IT, BT, ET, ST, NT, CT)를 기 준으로 내용을 조사하고, 내용의 서술 범주를 분석하였다. 분석 결과, 교육과정이 개정될수록 첨단과학기술분야의 내용이 증가함을 알 수 있었다. 중학교 교육과정 보다 고등학교 교육과정에서 첨단과학기술분야의 내용을 다수 제시하고 있었으며, 각 교육과정마다 특정 첨단과학기술 영역의 내용을 강조하고 있었다. 또한 교육과 정이 개정될수록 첨단과학기술분야의 원리가 증가하고 첨단과학기술의 기초 및 영 향은 감소함을 알 수 있었다. 따라서 현재 논의 중에 있는 2009 개정 교육과정에 따 라 개발될 과학 교과서에서는 학생들이 흥미를 갖도록 첨단과학기술과 과학 교과 와의 연계성을 고려하여 학습자의 수준에 맞는 첨단과학기술 내용을 제시해야 할 필요가 있다. The study purported to examine the science content on advanced science technology across the 7th Curriculum and its revisions from 2007 to 2009. The contents were divided into 6 technology areas which are IT, BT, ET, ST, NT, and CT and within each category. And the format of the learning content was also analyzed. The results indicated that with more revisions, the content on the advanced science technology increased. High school text books deals more content on the advanced science and technology than the middle school text books, and each revisions had specific emphasis on various topics pertaining to the advanced science technology. Also along the revisions, the content on the principles of advanced science technology increased, and instead, its fundamental aspects and the consequences decreased. Therefore it is suggested that the 2009 revisions should incorporate learning content that can elicit students interest in science subjects by linking them with advanced science technology from the learner-centered stances.

장지영(Ji-Young Jang),문기범(Ki-Beom Moon),하장호(Jang-Ho Ha),박지선(Ji-Sun Park),김미진(Mi-Jin Kim),전재흥(Jae-Heung Jeon),이긍주(Geung-Joo Lee),김현순(Hyun-Soon Kim) 한국원예학회 2015 원예과학기술지 Vol.33 No.6

토양 전염균인 Fusarium oxysporum f. sp. lilii(Fol)은 식물에 심각한 위협을 주는 균으로 특히 백합의 구근과 꽃에 심각한 영향을 준다. 따라서 저항성 품종의 육성이 중요시되고 있는데, 저항성 품종이 육성되기 위해서는 신속, 간편한 검정법 체계와 유전적 다양성이 요구되는 상황이다. 본 실험에서는 기내배양시스템을 이용하여 백합의 Fol에 대한 저항성 정도를 효율적으로 검정하는 방법을 확립하고자 하였다. 병원균의 배양조건, 병원균의 식물체 접종 농도, 대상 절편체 종류, 접종 후 적정 발병 기간 등과 같은 조건을 단독, 혹은 조합하여 실험 한 결과 다음의 기내검정조건을 확립하였다. Fol균을 6일 동안 PDA 배지에서 배양한 후 포자현탁액을 1.0 × 10⁴ spores·mL<SUP>-1</SUP> 농도로 조절하여 기내배양중인 식물체의 잎을 1.5 × 2.0㎠의 크기로 절단하여 25℃, 암조건에서 22시간 침지시켜 접종하였다. 접종이 끝난 잎절편체는 0.6% 한천배지에 치상하여 온도 25℃, 습도 50%, 16시간 광조건(광도 40μ㏖·m<SUP>-2</SUP>·s<SUP>-1</SUP>)을 유지하면서 병의 발달을 관찰하였다. 발병 정도를 지수화하여 통계처리를 하였다. 기내검정을 통하여 저항성 및 민감성으로 선발한 백합종들을 토양검정법으로 실험한 결과 동일한 저항성 정도를 얻을 수 있었으며, 이는 본 연구에서 확립한 Fol에 대한 구근부패병 기내검정법이 효율적으로 품종 선발에 이용될 수 있음을 보여준다고 하겠다. The soilborne fungus Fusarium oxysporum f. sp. lilii (Fol) is a serious threat to all lily cultivars, especially infecting bulbs and flowers. It has become increasingly important to develop varieties resistant against the bulb rot disease. Genetic diversity of cultivars and reliable screening methods are required for this purpose. Here, an efficient in vitro screening system for evaluating resistance to Fol in 38 in vitro-grown lily plants was investigated. Various factors including culture conditions of Fol, inoculum density, appropriate plant materials, inoculation method and duration, and incubation period of plant materials after inoculation were combined to optimize the screening method. As a result, we suggest optimal conditions for an in vitro screening system for the selection of Fol-resistant lily cultivars as follows. Fol was grown on potato dextrose agar (PDA) medium for 6 days at 25℃ in darkness and used as working inoculation. Spore suspensions were prepared (inoculum density: 1.0 × 10⁴ spores·mL<SUP>-1</SUP>), and then leaf segments 1.5 × 2.0 ㎠ were inoculated by dipping for 22 hours at 25℃ in dark. Later, leaves were cultured on 0.6% agar plates at 25℃ and 50% humidity with a photoperiod of 16 hours light/8 hours dark (fluence rate of 40 μ㏖·m<SUP>-2</SUP>·s<SUP>-1</SUP>) to examine the progress of bulb rot. After 7 days, disease levels were classified into indices 1 (no symptom) to 6 (serious bulb rot). Soil inoculation of Fol carried out with resistant or susceptible lily cultivars that had been selected through in vitro screening confirmed the reproducibility of results. Therefore, the in vitro screening method established in this study is efficient and reliable for selection of lily cultivars resistant against bulb rot disease.
