The spatial and temporal variations of CO2 concentrations and radiative forcing (RF) due to CO2 were examined at urban center (Yeon-dong) during 2010-2015 and background sites (Gosan) during 2010-2014 on Jeju Island. The RF at the two sites was estimated based on a simplified expression for calculating RF for the study period. Overall, annual mean CO2 concentrations at the Yeon-dong and Gosan sites have gradually increased, and the concentrations were higher at Yeon-dong (401-422 ppm) than at Gosan (398-404 ppm). The maximum CO2 concentrations at the two sites were observed in winter or spring, followed by fall and summer, with higher concentrations at Yeon-dong. The RF at Yeon-dong (annual mean of up to 0.70 W/m2 in 2015) was higher than that at Gosan (up to 0.46 W/m2 in 2014), possibly because of higher CO2 concentrations at Yeon-dong resulting from population growth and human activities (e.g., fossil fuel combustion). The highest monthly mean RFs at Yeon-dong (approximately 0.92 W/m2) and Gosan (0.52 W/m2) were observed in spring 2015 (Yeon-dong) and spring 2013 (Gosan), whereas the lowest RFs (0.17 and 0.31 W/m2, respectively) in fall 2011 (Yeon-dong) and summer in 2012 (Gosan).

Background and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

저용량 Cyclosporine-A와 Diltiazem 병합요법에 의한 신증후군의 관해

김성은,정연순,임학 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.3

Background : Cyclosporine-A (CsA) has been widely used as a treatment of nephrotic syndrome especially in patients with steroid-resistance or steroid-dependence. However, it can be nephrotoxic and its cost might also be a point to be considered. Diltiazem (DZ), one of calcium channel blockers, may have a potential benefit of renoprotection, which decreases acute tubular necrosis of renal transplants. DZ can also be used for reducing CsA dose because it slows down the metabolism of CsA by inhibition of cytochrome P-450 hepatic enzyme. In these points of view, low-dose CsA with DZ combination could be considered as an alternative to nephrotic syndrome treatment. However, such a kind of trial was hardly found so far. The purpose of this study was to evaluate the therapeutic effect of low-dose CsA with DZ in patients with steroid-resistant or steroid-dependent nephrotic syndrome. Methods : Low-dose of CsA (mean 1.7±0.5 mg/kg) and 90 mg of DZ were administered simultaneously to 15 patients of steroid-resistant or steroid-dependent nephrotic syndrome for 6 months with no alteration of dose. Blood pressure, body weight and random urine protein, 24-hour urine protein, serum creatinine, albumin, total cholesterol, and trough level of CsA were analyzed. Results : The random urine protein tended to decrease by CsA treatment. Twenty-four hour urine protein excretion decreased significantly at 6th months of treatment (from 7,211±5,374 mg to 1,094±1,688 mg, n=7, p=0.018). Complete remission was achieved in 10 patients and partial remission in 5 patients. Changes in serum albumin, total cholesterol, hemoglobin, body weight and blood pressure were statistically not significant. Conclusion : Low-dose CsA combined with DZ may be an effective in patients with steroid-resistant or steroid-dependent nephrotic syndrome.

This study is to examine the thermal properties such as the heat keeping property and the warm/cool feeling of quilting underwear, using Thermo Labo Ⅱtype. The specimens used for this study are five kinds of quilting underwear and each one of cotton and wool underwear. The correlativity is investigated by measuring the structural properties under the standard condition(20℃, 65% RH) and the thermal properties in changing the relative humidity of 55, 65, 75, 85, 95% at 20℃. The summarized results of this studies are as follows. 1. The heat keeping rate and the qmax value of quilting underwear have a high degree of correlation with structural properties such as thickness, bulk density and porosity. As above results, the regression equation is as follows. Y_HK=1.2950X_p-85.6586X_D-3.7254X_T-37.7610(r^2=0.9566) Y_qmax=154.7298×10^-3X_D-14.3396×10^-3X_T+0.2703×10^-3X_P+0.0557(r^2=0.9707) 2. The heat keeping rate of specimens is in the order of quilting underwear > wool underwear > cotton underwear. And also, the qmax value of specimens is in the order of cotton underwear > quilting underwear > wool underwear. 3. In according to increase of the relative humidity, the heat keeping rate tends to be lower but the qmax value is to be larger. Therefore, the degree of decrease of the heat keeping rate is in the order of cotton underwear > wool underwear > quilting underwear and the degree of increase of the qmax value is in the order of cotton underwear > quilting underwear > wool underwear. And also, in the fiber content per areal weight composing quilting underwears, the degree of change of the thermal properties by changing relative humidity is remarkable when hydrophilic fiber content comes to be greater.

문화재란 문화가치가 있는 사물로서 국가 가 종교적·세속적 근거에 따라 특별히 지정 한 재산이다. 문화재는 그것이 구현하는 정신적 가치와 시각적 음향적으로 표현하는 수단으로서 그 나라의 독특하고, 다양한 주체성을 보존하는 중요한 매체이기도 하다. 그러므로 문화재는 한나라의 민족역사와 문화로서 과거의 모습을 통해 현재 그리고 나아가 미래를 연결시키는 하나의 매개체인 것이다. 또한 문화재는 그 지역민에게 향토사적 인 자긍심 및 연대의식을 고취시키는 동시에 나아가 한 나라, 세계적인 관심사로 여겨 야 할 것이다. 원적산 봉수대는 양산군청 소재지에서 북쪽으로 약 9.2㎞, 통도사입구 마을인 신평에서 남쪽으로 8㎞지점에 있다. 이 봉수대는 경상남도 기념물 제 118호로써 원적산봉수대 보존회에 의해 복원된 문화재이다. 즉 다른 지역의 문화재와 달리 잊혀 져가는 문화재의 재생을 통해 다시 태어난 문화재인 것이다. 원적산 봉수대 주변정비 기본계획의 목적 은 지역민의 자긍심으로 복원된 봉수대와 주 변과 접근로를 체계적으로 정비를 함으로써 접근성, 전통성, 보존성을 높이고자 한다. 특히, 문화재보호를 위한 제반 법규 및 현지여건에 부합하는 정비방향을 설정하고, 전문 인력과 관련문헌을 바탕으로 문화재 주변을 역사성과 주민친화성, 기능성, 관광성을 함께 갖춘 문화공간으로서의 미래지향적 문화재정비 계획을 추구하고자 한다.

The concept of revascularization of necrotic pulps regained interest and became an alternative conservative treatment option for young permanent teeth with immature roots. Revascularization of immature teeth with apical periodontitis depends mainly on disinfection of the canal. Since the infection of the root canal system is considered to be polymicrobial, a combination of drugs would be needed to treat the diverse flora. A triple antibiotic mixture of metronidazole, ciprofloxacin, and minocycline was used as an intracanal medicament. However, discoloration was developed after applying the triple antibiotic mixture. It is believed that the marked discoloration is related to the use of minocycline. The aim of this article was to present cases of coronal discoloration after triple antibiotic therapy in immature tooth and was treated with bleaching technique to control coronal discoloration. In conclusion, revascularization by using triple antibiotics promotes a paradigm shift in treating endodontically involved permanent teeth. However, we should understand that triple antibiotics containing minocycline induces tooth discoloration. Further research to prevent coronal discoloration should be investigated and suggested for the safe use of triple antibiotics. 괴사된 미성숙영구치의 치수치료에 있어서 치수의 재혈관화를 통해 치근단 발육 및 치근형성을 지속하려는 개념이 소개됨 으로써 현재 미성숙영구치의 치수치료의 대안으로 제시되고 있다. 이러한 치근단 염증을 가진 미성숙 영구치의 재혈관화를 위해서는 가장 중요한 것이 근관내 감염된 부분을 확실히 제거하는 살균(disinfection)이다. 근관 내 감염은 여러 세균의 복 합작용으로 일어나기 때문에 철저한 살균에 사용되는 약제의 조합은 다양한 범위의 균주를 모두 제거 가능해야한다. Metronidazole(MN), ciprofloxacin(CF), minocycline(MC)의 세 가지 복합항생제가 약제로 사용되고 있으나 이 복합항생 제 적용 후 치관변색을 일으키는 사례가 보고되고 있다. 이러한 치관변색은 항생제의 성분 중 MC에 의한 것으로 여겨지고 있으며, 본 증례에서는 복합항생제 적용에 의해 야기된 치관변색의 증례를 소개하고 이를 표백술로 처치하여 최종 수복한 증 례를 보고하였다. 복합항생제 적용을 통해 미성숙영구치의 치수치료에 새로운 패러다임을 제시한 것은 분명하지만 치관변색 등의 부작용이 있음을 인지하고 치관변색을 사전에 예방하고 최소화하기 위해 다양한 방법이 강구되어야 할 것이다.
