The author has evaluated the transcranial oblique lateral images of the mandibular condyle according to the angulation of the radiation projection. The lead foils were attached to both condylar poles and two thin wires were attached to the superior border and posterior border of the condyle. The mandibular condyle was located on the device designed specially. The materials consisted of 56 transcranial oblique lateral projections. The results were as follows: 1. It was possible to find the point of the retroepicondyle at angles of H-1OVO. HOVO, H-1OV5, HOV5, HOV1O and H1OVO - H1OV35(H:horizontal angulation. V:vertical angulation). 2. It was impossible to find the osteosclerotic line located in the anterior portion of the condyle on transcranial oblique lateral view at angles of H2OVO, H2OV5, H3OVO. H3OV5, H3OV1O. The length of the osteosclerotic line was positive horizontal angulation. but the distance between the osteosclerotic line and the superior border of the condyle was getting closer. 3. When the vetical angulation increased. the smooth posteior border line of the condyle was getting angulated with the increase of the positive horizontal angulation and getting curved sharply with the increase of the negative horizontal angulation. 4. We might misinterpret the shape of the medial pole as the ostophyte seen in osteoarthrosis with the increase of the negative horizontal angulation. 5. The inclination and the distance between both condylar poles were getting increased with the increase of the horizontal and the vertical angulation.

Eight monitoring stations in the Yeosu National Industrial Complex will determine the concentration of air pollutants measured every hour in 2019, analyze what factors affect them, and how they correlate with the air pollutant measurements. Six air pollutants (SO2, NO2, O3, CO, PM-10 and PM-2.5) measured at eight monitoring stations around Yeosu National Industrial Complex (Seogang-dong, Wolnae-dong, Munsu-dong, Yeocheon-dong, Deokchung-dong, Hwayang-myeon, Yulchon-myeon, Samil-dong) the measurement data for each hour of the year were downloaded to analyze the concentration by weather condition, time zone, season, separation distance from Yeosu Industrial Complex, and separation distance from Gwangyang Industrial Complex. SO2, NO2, and CO concentrations were significantly higher in winter, significantly lower in summer, and O3, PM-10, and PM-2.5 concentrations were significantly higher in spring. SO2, CO, PM-10, and PM-2.5 concentrations were significantly higher between 10 a.m. and 12 p.m., NO2 concentrations were significantly higher between 7 a.m. and 9 a.m., and O3 concentrations were significantly higher between 13 p.m. and 15 p.m.(p<0.001). The concentration of air pollutants (SO2, NO2, CO, PM-10, PM-2.5) excluding O3 was found to have a negative (-) correlation with weather condition, and in the case of O3, it was found to have a positive (+) correlation with PM-10, PM-2.5, temperature and wind speed. It was confirmed that the concentration of air pollutants emitted from the Yeosu National Industrial Complex differs depending on the season, time and distance to the industrial complex. This study aims to establish measures to minimize health damage to residents living relatively close to the industrial complex and contribute to the establishment of management and response measures according to the properties of substances to reduce the concentration of air pollutants in the future.

To investigate the effect of high dose irradiation on the mechanical properties. dental acrylic resin specimens were irradiated and the Vickers hardness number(VHN) and the 3-point flexure strength(FS) were measured before and after irradiation. Five kinds of acrylic resins were studied. Two(VRS. PS2) were heat cured denture base resins. one(VSC) was chemically cured denture base resin and the other two(ORJ, VOP) were orthodontic resins. The acrylic resin specimens were made according to the manufacturer's instructions and were finally polished with Microcloth (Buehler). Among ten specimens of each material. five specimens were irraditated with 100 Gy using a linear accelerator (Mitsubishi 6 MV), and the others were not. The specimens were immersed in 37℃ D.W. for 48 hours before testing. Each specimens the VHN was measured 10 times. Their FS was measured with an universal testing machine (Instron 4302, England), with a cross-head speed of 5 mm/min. The VHNs of heat cured resins were 21.52∼25.55 kg/㎟ before irradiation and 19.93∼26.58 kg/㎟ after irradiation. Those of chemically cured resins were 11.28∼16.6kg/㎟ before irradiation and 11.3∼14.3 kg/㎟ after irradiation. The VHNs of heat cured acrylic resins were significantly higher than those of chemically cured resins were significantly higher than those of chemically cured resins before and after irradiation(p<0.05). VHN of VRS was significantly increased after irradiation, and those of VOP and PS2 were significantly decreased after irradiation (p<0.05). The FS of resins studied were 6.7∼8.0 kg/㎟ before irradiation and 6.5∼8.4 kg/㎟ after irradiation. The FS of VSC and VRS increased after irradiation and those of VOP, ORJ and PS2 decreased after irradiation, but the results were not statistically significant. Before irradiation, the FS of heat cured resins were somewhat higher than those of chemically cured resin, but not statistically significant, and after irradiation the FS of heat cured resins were significantly higher than those of orthodontic resins. In conclusion. high dose irradiation did not result in consistent changes in mechanical properties.

Acute myocardial infarction(AMI) due to coronary embolism can occur in patients with normal coronary artery. Coronary embolism is believed to be a cause of acute myocardial infarction when emergent coronary angiography shows perfectly normal coronary trees, except for the finding of coronary artery occlusion. In this report, we describe four patients with AMI due to coronary embolism who were successfully treated using a thrombus aspiration device and anticoagulation, and those patients had intracardial thrombus arising from the left atrium due to chronic atrial fibrillation and valvular heart disease. Patients with chronic or paroxysmal atrial fibrillation can present with AMI due to coronary embolism, and thrombus aspiration with percutaneous aspiration device is a feasible treatment option for these patients along with anticoagulation the rapy.

문화예술계 성 인권 보호를 위한 제도 연구

변영건(Byun, Young geon),이승엽(Lee, Sung yeop) 한국예술경영학회 2020 예술경영연구 Vol.0 No.54

본 연구는 미투 운동 이후 시작된 문화예술계 성 인권 보호 제도의 흐름을 점검하고 이에 대한 개선 방향을 제안하는 것을 목표로 한다. 그동안 정부에서는 ‘범정부 합동대책’, ‘문화예술계 성희롱·성폭력 특별조사단 권고’, ‘문화체육관광부 성희롱·성폭력 예방대책위원회의 1·2차 권고’, ‘문화비전 2030’를 발표하고, 이를 토대로 문화예술계의 성 인권 보호 제도를 설계했다. 이후 시행된 제도는 구체적으로 피해자 보호, 가해자 제재, 예방·방지책 마련, 법적 근거 및 제도 틀 개선의 4가지 범주로 분류할 수 있었다. 하지만 정부의 다각적인 노력에도 불구하고 현장에서는 제도의 실효성이 높지 않다는 비판이 끊임없이 제기됐다. 피해 당사자의 목소리로 말미암아 성평등 문화정책이 진척을 이룬지 2년이 흐른 지금, 현장에서 진정한 변화를 만들어내기 위해서는 현행 제도의 진단과 개선 방향에 관한 논의가 필요한 시점이다. 이를 위해 정부 발간자료 등을 기반으로 한 문헌 연구와 정책 기획·실행 단계의 주요 행위자 9명과의 인터뷰 내용을 바탕으로 한 면접 분석연구를 진행했다. 인터뷰 내용 분석에는 질적 연구 분석 프로그램인 MAXQDA를 활용했다. 연구 결과 제도의 범주별로 각각 5~10가지 문제점이 드러났다. 문제 해결을 위해 인터뷰이들이 제시한 개선 방향에서는 긴밀한 연관 관계가 확인됐다. 이는 성 인권 보호를 위한 제도가 유기적으로 연결되어야 효과를 낼 수 있음을 시사한다. This study aims to examine the system for gender rights in arts and cultural industry triggered by #Metoo movement and to suggest action plans to improve gender equality. Up until now, Korean government launched ‘Pan-governmental Counter Plan’, ‘Recommendation of the Special Center for Investigating Sexual Harassment and Sexual Violence in Arts and Cultural Industries’ ‘the Primary and Secondary Supplemental Measures to Eradicate Sexual Harassment and Sexual Violence in the Arts and Cultural Sector by the Ministry of Culture, Sports and Tourism in Korea’, and ‘2030 Cultural Vision’. Korean government has designed the system to protect gender rights using these proposals. Implemented policies can be grouped into 4 different categories; protecting victims, punishing abusers, implementing preventive measures, and reforming legal system. However, despite Korean government’s multilateral efforts, continuous criticism aroused as policies failed to witness actual impacts in the industry. Given the fact that 2 years have passed since the launch of gender equality policy in cultural sector, this is the right time to discuss the current status and ways to improve it. For above reasons, research was conducted on documents including, but not limited to, government publications and an analysis of interviews with 9 major stakeholders of policy planning and implementation. During the study, interviews were analyzed using the qualitative research program MAXQDA. As a result, 5~10 problems were revealed in each category of the system. Furthermore, meaningful correlation has been found in improvement areas suggested by the interviewees. This connection implies that the policy for gender rights in arts and cultural industry shall be developed organically in order for the system to work.

Effect of Charcoal Broiling on the Formation of Volatile Compounds in Gamma-Irradiated Dakgalbi, a Korean Chicken-Based Food

Geon Ok Kang,Young Min Yoon,Jae Kyung Kim,Beom Seok Song,Eui Baek Byun,Jae Hun Kim,Ju Woon Lee,Jong Heum Park 한국축산식품학회 2013 한국축산식품학회지 Vol.33 No.5

The purpose of this study is to evaluate the change of volatile compounds in Dakgalbi cooked by charcoal broiling. Fresh deboned and marinated chicken meat was cooked by electric-pan frying or charcoal broiling and subsequently irradiated with a dose of 0, 10 and 20 kGy. Volatile components from Dakgalbi were analyzed using solid phase micro-extraction gas chromatography - mass spectrometry (SPME GC-MS) and identified through the comparison of mass spectrum database. SPME GC-MS analysis shows that a total of 32 volatiles were identified. Among them, aldehydes such as hexanal and octanal, which have relevance to off-flavors such as green, paint, metallic, bean and rancid were detected in Dakgalbi cooked by both methods. However, the contents were less detected in the Dakgalbi cooked by charcoal broiling than in the Dakgalbi cooked by electric-pan frying. Gamma-irradiation caused the change in the formation of these aldehydes in cooked Dakgalbi. The irradiation significantly increased the contents of hexanal and octanal in Dakgalbi cooked by electric-pan frying and a similar increase was found in Dakgalbi cooked by charcoal broiling. However, the contents of the off-flavors were much less in the latter. The results suggest that charcoal broiling might be more effective than electric-pan frying for the reduction of the contents of off-flavor such as hexanal and octanal increased in Dakgalbi by gamma-irradiation.
