To evaluate the significance of serum beta₂-microglobulin in patients with various liver diseases, serurn Beta₂ m levels were measured in 44 cases of normal controls, 32 cases of asymptomatie HBsAg carriers and 134 patients with various liver diseases, by radioimmunoassay using Phadebas Beta2~micro test kits. The following results were obtained: I) The mean level of serum β₂ m was 1 39+-0.25㎎/ℓ(Mean+-S.D.) in normal controls (1.39+-0.23㎎/ℓ in 24males, 1.38+-0,27㎎/ℓin 20 fernales). 2) The seram levels of B2m in patients with various Iiver diseaaes and asymptomatic HBsAg carriers were as follows; 1.400.27㎎/ℓ in asymptomatic HBsAg carriers, 2.42+-0.377 mg/l in 45 patients with acute viral hepaitis, 2.10+-0.26 mg/l in 46 patients with chronic persistent hepatitis, 2.60+-0.34㎎/ℓin 23 patients with chronic active hepatitis, and 2.60+-0.49 ㎎/ℓin 20 patients with liver cirrhosis. Serum β₂ m levels of each disease group were significantly higher than that of normal controls(p$lt;0.001). 3) There was significant correlation between the levels of serum β₂ m and the degrees of lymphocytic infiltration in patients with chronic active hepatitis(p$lt;0.001). 4) Significant correlations were observed between the levels of serum betA₂,-microglobuin and serum alanine aminotransferase(r=0.68, p$lt;0.05) and bilirubin(r=0.63, p$lt;0.05) in 15 patients with acute viral hepatitis. In conclusion, the serum beta₂,-microglobulin levels were increased in patients with various liver diseases, and it may serve as a new index of liver disease activity.

Carbon dioxide produced from biomass is biogenic. It is considered to be neutral carbon, and is therefore excluded from calculations of greenhouse gas emissions. In Korea, methods for calculating greenhouse gas emissions are categorized into Tiers 1 to 4, according to emission activities. Emissions measured by the methods in Tiers 1 to 3 are partially excluded from total CO2 emissions according to the proportion of biomass contained in the waste. The Tier 4 method measures CO2 emissions by measuring the amount and composition of the exhaust gas. However, this method does not consider the biomass content. In Tier 4, as in Tiers 1 to 3, it is necessary to partially exclude CO2 emissions from the greenhouse gas emissions in the flue gas according to the biomass ratio. In this study, the biomass content of SRF used in domestic facilities was analyzed using SDM. In addition, the biomass content of the exhaust gas from these facilities was analyzed using AMS. It was found that SRF contains 43.6% biomass on average. Furthermore, it was confirmed that the biomass content of the SRF used in facilities measured by SDM and the biomass content of the exhaust gases measured by AMS were similar.

Suicide is a major public health issue that causes over 800,000 deaths each year globally. Korea ranks high in suicide rates, in which around 24.3 per 100,000 individuals are reported to have died by intentional self-harm in 2017 according to Statistics Korea. The aim of this study was to examine the current status and trend of suicide ideation and attempt using data from the following five sources: Korean National Health and Nutrition Examination (KNHANES, ‘07–13, ‘15–17), Korean Community Health Survey (KCHS, ‘08–09, ’13, ’17), Korean Wealth Panel Study (KOWEPS, ‘12–17), Korea Health Panel Survey (KHP, ‘10–13), and Statistics Korea (1983–2017). Suicide ideation and attempts were also further examined based on equalized household income levels. Data published by Statistics Korea were used to show the updated suicide rate and number of deaths by intentional self-harm. The rate of suicide ideation at the recent year was 4.73% (KNHANES, ‘17), 6.96% (KCHS, ‘17), 1.63% (KOWEPS, ‘17), and 5.39% (KHP, ‘13). That of suicide attempts as recent year was 0.71% (KNHANES, ‘17), 0.32% (KCHS, ‘17), and 0.09% (KOWEPS, ‘17). Annual percentage change of suicidal ideation was -15.4% (KNHANES, ‘07–17), -2.5% (KCHS, ‘08–17), -8.6% (KOWEPS, ‘12–17), and -10.9% (KHP, ‘10–13). Annual percentage change of suicide attempts was -4.0% (KNHANES, ‘07–17), -4.4% (KCHS, ‘08–17), and -14.9% (KOWEPS, ‘12–17). Individuals with lower income levels were more likely to experience suicide ideation and attempts. Considering that Korea still shows a high suicide rate despite the continuously decreasing trend of suicide ideation and attempt, continuous observation and appropriate policy implementation regarding suicide related problems are necessary.

자전거 이용자를 위한 일회용 미세먼지 마스크 디자인 연구

권준호 한국디지털정책학회 2018 디지털융복합연구 Vol.16 No.12

Bicycle riders complain of many inconveniences when wearing glasses, sunglasses and masks. The disposable fine dust mask has been developed to resolve such inconveniences of bicycle riders. The scope of research is limited to the fiber which generates one-time static electricity and the shape of the mask due to the characteristic of fine dust mask. The purpose is to design and make the fine dust mask with a simple production process. The new disposable fine dust mask has secured enough space of the mask in front of the mouth by longitudinal folding and minimized stuffiness by maintaining the shape of the folded part to prevent touching the mouth even by heavy breathing. The streamlined sponge is attached at the part of nose support and the area of the cheek has been expanded to be about 2.5cm wider than ordinary masks to improve tight seal at the side. In addition, a new disposable fine dust scarf mask has been developed to block ultraviolet rays for the face and neck while filtering fine dust with the tight fine dust mask. 자전거 이용자가 안경 및 선글라스를 쓴 상태에서 마스크를 착용 할 때 여러 가지 불편함을 호소한다. 본 논문은 이러한 불편함을 보완하여 자전거 라이더들에게 필요한 일회용 미세먼지 마스크를 개발하는데 그 목적이 있다. 미세먼지 마스크의 특성상 일회성 정전기 발생 섬유와 마스크의 형태적 문제로 연구범위를 제한하고 기존 미세먼지 마스크를 간결한 제작공정으로 디자인한다. 이렇게 개발된 일회용 미세먼지 마스크는 세로방향 접힘으로 입 앞 마스크 내 공간을 충분히 확보하였고 거친 숨에도 입에 닿지 않게 접힘 부위형태가 유지 되게 하여 답답함을 최소화 하였다. 코지지대에 유선형 스폰지를 부착하고 안면 볼 부위를 일반마스크 보다 2.5cm 정도의 확장하여 측면 밀착성을 높였다. 또한 기존에 없던 일회용 미세먼지 스카프 마스크를 제작하여 안면과 목 부위 자외선을 차단하고 밀착성 높은 미세먼지 마스크를 개발하였다.

권준현,김재봉,이정우,최강영,정호윤,조병채,양정덕 대한미용성형외과학회 2016 Archives of Aesthetic Plastic Surgery Vol.22 No.3

Among autologous breast reconstruction techniques, breast reconstruction using the latissimus dorsi musculocutaneous flap is widely used, offering advantages including the relative simplicity of the procedure and the reliable and consistent vascularity of the flap. Accordingly, more than 500 cases have been performed in the past 8 years at Kyungpook National University Medical Center. This study reports on a rare case involving a radial nerve neuropathy complication which was experienced for the first time at the medical center. The current case demonstrates that in addition to common complications, such as seroma of the donor site and scarring, additional intraoperative complications in areas unrelated to the surgical site can occur, including radial nerve neuropathy in the opposite arm.

권준국,이재한,박경섭,최효길,유인호,조명환,벡조드,강남준 경상대학교 농업생명과학연구원 2017 농업생명과학연구 Vol.51 No.1

시설재배 멜론은 소득이 비교적 높고 시설 내 환경 변화에 민감한 작목이다. 특히 여름 고온기재배 시에는 광합성 저하와 호흡 증가로 인해 멜론의 생산성과 품질이 저조하다. 고품질 멜론 생산을 위해서 는 시설 내 기온과 습도를 적정 조절하는 것이 매우 중요하다. 본 연구는 고온기 멜론재배 시에 포그 및 공기유동팬을 이용한 온도와 습도 조절이 과실 품질에 미치는 효과를 구명하고자 하였다. 그 결과, 포그와 유동팬을 가동 할 때 시설 내 기온은 최대 7℃, 평균 3.2℃ 강하되었고 상대습도는 최대 28%, 평균 12% 상승하였다. 이러한 온도와 습도 조건의 영향으로 무처리(천창과 측창환기 실시)에 비하여 멜 론의 과중이 300g, 당도가 1.5°Bx 각각 높았다. Greenhouse grown melon(Cucusmis melo var reticulates) is a high-value and it is sensitive to change in environmental parameters. In summer growing season an indoor air temperature can rise to undesirable low level which can significantly affect melon photosynthetic ability, transpiration rates, thereby decreasing the fruit quality and yield. Keeping optimal or near optimal environmental conditions during melon production in greenhouse is important, since it will ensure high productivity. This experiment was conducted to investigate the effects of controlling temperature and humidity using fog system combined with air circulation systems on the fruit quality of greenhouse grown melon in a hot season of the year. Experiment showed that operation of fog system and air circulation fan in melon greenhouse lowered indoor temperature by 7.0℃(max) and 3.2℃(average) as well as elevated relative humidity by 28% (max) and 12.0%(average). Fruit weight and soluble solids of melon in greenhouse equipped with the fog system and air circulation fans were increased by 300 g and 1.5 oBx, respectively, compared to those in control greenhouses(with only roof and side windows).
