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.

연익준,박상찬 충주대학교 2006 한국교통대학교 논문집 Vol.41 No.-

Semi-dry reactor (S.D.R) system is used to evaluate the effect of spray characteristics for the removal of HCl in the flue gases, and in these experiment, the spray direction was co-current with flue gas and the two-fluid external mixing nozzle was used. And the HCl concentration of the treated flue gas was measured by the combustion gas analyzer (TMS system) on stack. In these experiment, we obtained the maximum removal efficiency of HCl in the incineration flue gas was 96% when atomization quantity of lime slurry was 600ℓ/hr and the Ca/Cl ratio was 3.36 and the slurry droplet size proved 24㎛. Also, the temperature of inlet flue gas into semi-dry reactor have to maintain over 300℃ since lower gas temperature can be caused condensing at the next bag filter.

본 논문은 다기준 의사결정 기법의 하나인 계층분석과정(AHP: Analytic Hierarchy Process)을 이용 하여 입지평가 모형을 수립하고 이에 대한 실증분석을 실시한다. 먼저 기존 연구를 통하여 입지선정 이 잘 이루어졌는지 확인하기 위한 평가요소를 도출하고 이를 이용하여 대학 사례에 대한 입지선정 평가모형을 수립한다. 평가요소들 간의 상대적 중요도를 파악하고 AHP를 적용하여 각 대안들 간의 우선순위를 산출한다. 대학 사례를 통하여 평가기준별 순위와 전체적인 순위를 제시하고 이에 따른 대학별 대응전략을 제시한다. 마지막으로 본 연구의 결과를 요약하고 향후 연구방향을 제시한다. This paper conducts an empirical analysis of location assessment using AHP(analytic hierarchy process), one of multi-criteria decision making techniques. First, we identify assessment criteria to evaluate location selection from literature review and establish a model of university location assessment based on identified criteria. Relative importance of each evaluation criterion is derived and then priorities of all possible alternatives are calculated. We rank each alternative by evaluation criteria and overall and propose responding strategies of the universities based on the evaluation results. Finally, we summarize the research and present future research direction

Recently, arguments have been forwarded regarding the significance of martial quality in investigating the family context of early childhood development. The current study examines the associations among marital quality, parenting behavior, and childrens competencies. One hundred seventy eight mothers of preschool children served as subjects. Mothers completed the questionnaires concerning marital quality, parenting behavior, and childrens competencies. The main results were as follows: 1) Mothers marital quality appeared to be positively associated with mothers parenting behavior; Mothers who were happily married inclined to show more reasoning guidance, consistent limit setting an intimate behavior. 2) Mothers marital quality is positively related to childs competencies. 3) Among the selected demographic variables, childs sex and mothers education were the significant variable related to childs competencies. 4) Reasoning guidance, marital quality, childs sex, and intimacy were found to be most significant variables to predict the level of childs competencies. 5) Marital quality has not only direct association but also indirect association through parenting behavior with childs competencies. In conclusion, The hypothesis that good marital quality would be associated with good parenting and childrens competencies was generally supported by the data. Direct and indirect associations between the demographic variables (the mothers educational level and the childs sex), marital quality, parenting, and childs competencies are discussed.

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.

18세기의 유희음악 : 디베르티멘토(Divertimento) Divertimento

연상춘 이화여자대학교 음악연구소 2001 이화음악논집 Vol.5 No.-

Die Zeit um 1720/30 ist in der europa¨ischen Musikgeschichte eine Umbruchszeit, die dann ungefa¨hr um die Zeit von 1780, also der sogenannten klassischen Zeit ihren Ruhepunkt gelangt. In der Musikgeschichte ist diese Umbruchszeit im Sinne von U¨bergangszeit als "Vorklassik" bezeichnet. Diesen Umbruch herbeifu¨hrende hauptursache aber war u. a. eine politisch-soziale. Weg von der hauptsa¨chlich unter der barocken "ancien re'gime" getragenen kulturellen Form wird jetzt die von der bu¨rgerlichen zum Vordergrund geru¨ckt. Im musikalischen Gebiet fand diese neue Stilwandlung u. a. in der instrumentalen Musik ihre haupta¨uBerung. Die neue Tradition der Instrumentalmusik wird nun in Gang eingestzt. Dies ermo¨glichender Hauptta¨ger war die Gattung "Divertimento". Trotz dieser geschichtlich wichtigen Stellungsnahme des Divertimentos ist es in der Musikgeschichtsschreibung bis vor kurzem viel zu sehr musikalisch abseits behandelt. Ru¨ckblickend kann man sagen, daB dies - auch zumindest um die Pha¨nomene der klassischen Musik kla¨ren zu ko¨nnen - nicht richtigen Weg war. Dafu¨r war die Art der Musik viel zu wichtig. Viele neulich stattfindende wissenschaftliche Diskussionen sagen dies. Der Zielpunkt der vorliegenden Untersuchung war also diese spezifische Gattungsgeschichte Divertimentos der vorklassischen Zeit unter mo¨glichst vielfa¨ltigen Aspekten aufzuzeigen, um dann hieraus u¨ber das Pha¨nemen desselben ein anna¨hrendes Bild zu machen. Hierfu¨r ist die Arbeit groB in drei Sachgebiete eingeteilt, und schrittweise vorangegangen: Zuna¨chst wurden Fragestellungen angesammellt, Untersuchungsfeld angegrenzt und u¨ber vorla¨ufige Forschungsstand berichtet. Im na¨chsten Schritt - d. i. theoretischer Teil dr Untersuchung - wurde dann damalige musikalische Entwicklung betreff des Divertimentos nach geographisch gegebenen Lagen getrennt beobachtet, und hierauf die "Unterhaltungsmusik des 18. Jahrhunderts" zu definieren versucht. SchlieBlich im letzten Teil der Arbeit wurde mit bisher sich crgabenden Ergebnissen zusammen um die Sache des Divertimentos zu definiten unternommen. Dabei sind anhand der Quellen aus 18. Jahrhundert und neulichen Untersuchungsergebnissen mo¨glich alle Arten der Divertimento - Musik, also wie Serenade, Notturno, Cassation, Pattia, - diesmal im gattungsspezifischen Sinne - Divertimento nach deren Funktion, musikalischen Inhalt und der Stil aufzuzeigen versucht. Es ergab bzw. besta¨tigte sich daraus, daB diese Gattung Divertimento ein typischer instrumentaler Vertreter der vorklassischen Zeit anzusehen ist und daru¨ber hinaus nicht im allgemeinen Sinne auf der europa¨ischen Ebene, sondern besonders im su¨dlichen katholischen Teil der Europa gepflegt wurde. Also sie war in diesem Sinne sozusagen eine geographisch begrenzte Teitendenz, die in der U¨bergangszeit besonders im o¨sterreichischen Raum a¨uBerst beliebt gepflegt war, mit einer starken sozialcn Funktion, Die Musik, die ausschlieBlich instrumental ist, wurde zumeist in Klein-Besetzumgen aufgefu¨hrt. Hauptstilmerkmal ist u. a. eine Einfachheit und Versta¨ndlichkeit, wobei zur akustischen Unterhaltung auch kontrapunktische Arbeitsweise angewendet werden konnte. Viele Arten von Divertimento wie Serenade, Nottumo, Cassacion und nochmals Divertimento - in diesem Sinne ist Divertimento also ein Sammelbegriff deratigen Musik zu verstehen - sind andereseites in dieser Gestalt besonders fu¨r die damaligen angehenden Komponisten als ein beliebt musikalisches Experimentsfeld fungiert. Erst durch diese vielmalige Versuchen und dialektischen ProzeB auch mit der gegnerischen musikalischen Stellungsnahme war daraus der klassische kammermusikalische Stil hervorgegangen.

Chinese hamster 난소세포에서 수용성 니켈에 의해 특징적으로 발현되는 유전인자들의 빠른 분석에 관한 연구

성근제,이상한,우기민,송호연,조만희 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.2

니켈에 의한 암 발생기전 및 세포 독성기전을 이해하고 니켈에 의해 발현에 변화를 보이는 유전자들을 검출하기 위하여 니켈이 포함된 배지에서 배양된 Chinese hamster난소 세포부터 mRNA differential display 분석을 시행하였다. 본 연구에서는 동위원소나 DNA염기서열 분석용 젤을 사용하는 기존의 방법 대신에 훨씬 빠르고, 다루기 쉽고 안전성을 지닌 변형된 기법을 개발하여 적용하였다. 니켈에 의해 발현에 변화를 보이는 cDNA fragments들을 10% polyacrylamide mini젤상에서 분리 및 클로닝한 다음, DNA염기 서열 분석과 GenBank Blast search 프로그램을 이용하여 상동성 조사를 하였다. Reverse Northern blot을 이용하여 발현에 변화가 있는 cDNA들을 재확인한 결과, 검사된 19 cDNAs 들중 총 9종에서 발현의 변화를 보였으며, 이 중 3종은 니켈에 반응하여 발현에 증가를 보였고, 반면에 6종은 발현이 감소하였다.
