본 연구는 2004년부터 2008년에 걸쳐 강원도 자연환경연구공원 내 산림 및 주변 산림지역을 대상(조사구역 I: 호수 및 주변 수변생태계, 조사구역II: 인가 및 주변 산림생태계, 조사구역Ⅲ: 산림생태계)으로 육상 포유동물의 종다양성과 분포현황 및 변화양상을 조사한 것이다. 본 연구 동안 멸종위기종인 하늘다람쥐, 수달, 삵 등이 연구지역 내에 서식하고 있는 것을 확인하였다. 포유동물의 종다양성은 인가 접경 산림인 조사구역II보다는 수변지역인 조사구역I과 산림지역인 조사구역III에서 다양도가 더 높은 경향을 보였다. 종다양성의 변화는 2006년에 다소 증가했으나 2007년부터 미세하게 감소하기 시작했다. 그러나 종수의 미세한 감소와는 달리 개체수는 2007년부터 매우 크게 감소하는 경향을 보였다. 따라서 연구지역 내 산림에서 포유류의 종다양성과 개체수를 일정하게 유지하기 위한 방안을 마련할 필요가 있다.

한국은 제2공화국시대를 제외하고 건국 이래 계속 단원제를 유지했다. 최근 헌법개정논의과정에서 단원제에서 양원제로 변경하려는 움직임이 있다. 한편 이웃나라인 일본은 메이지(明治)헌법시대부터 계속 양원제를 채택해왔다. 메이지 헌법 시대의 제국의회는 '貴族院'과 '衆議院'이라는 두 가지 의회로 구성되었다. 메이지 헌법 시대에는 국민으로부터 선출된 중의원의 독주를 견제하고 天皇制를 유지하기 위해 皇族이나 귀족으로 구성된 귀족원을 두는 양원제를 채택하였다.제2차 세계대전이 끝나고 GHQ(General Headquarters: 聯合國軍 最高司令官 總司令部)의 주도하에 새로운 헌법을 작성함에 있어서 단원제로 변경하려고 하였다. 그러나 일본정부가 양원제 유지를 희망하였기 때문에 양원 모두 국민에 의해 선출되는 것을 조건으로 양원제가 계속되었다. 현재 일본 국회는 메이지 헌법 시대부터 존속하는 '衆議院'과 귀족원 대신에 새롭게 생긴 '參議院'의 두 가지 의원으로 구성된다. 현재 일본에서는 참의원이 실질적으로 중의원과 거의 구별이 없어졌음을 이유로 '參議院 不要論'이나 '參議院 改革論'이라는 논의가 제기되고 있다. 따라서 건전한 양원제 운용을 위하여 참의원의 존재의의에 대해서 진지하게 검토할 필요가 있다.

We report the results of our high resolution optical spectroscopic monitoring campaign (⋋ = 3800 ~ 8800 Å, R = 30000 - 45000) of the new FU Orionis-type object HBC 722. We observed HBC 722 with the BOES 1.8-m telescope between November 26 and December 29, 2010, and FU Orionis itself on January 26, 2011. We detect a number of previously unreported high-resolution K I and Ca II lines beyond 7500 Å. We resolve the Hα and Ca II line profiles into three velocity components, which we attribute to both disk and outflow. The increased accretion during outburst can heat the disk to produce the relatively narrow absorption feature and launch outflows appearing as high velocity blue and red-shifted broad features.

The objective of this study was carried out to evaluate the efficiency of sperm collection methods on the post-thaw viability of cat semen. The cat semen was collected by artificial virginal (AV) and electronic ejaculate (EE) methods. The composition of semen extender was consisted of Tris-buffer supplemented with 20% egg yolk and 1% P/S antibiotics in Ext I, and more added 8% glycerol, 1.0% Equex STM paste of total volume in Ext II. The collected semen was adjusted the concentration and then diluted in Ext I for optimal concentration. The diluted semen was cooling to 5℃ temperature in refrigerator for at least 2 hrs and then diluted stepwise with Ext II for at least 1 hrs. After an equilibration for 1 hrs, the cooled semen was packaged in 0.5 ml straw and then freezing on the LN2 vapor over 5 cm above from LN2 and then immersed directly in LN2 for cryopreservation. The frozen semen was thawed in 38℃ water for 15 sec and then evaluated the motility, viability, and morphology. Post-thaw semen were calculated the motility by SMI (sperm motility index). The live-dead sperm was evaluated by Eosin-B and morphological evaluation was by Diff-quik kit staining. The post-thaw concentration (89×106 /ml vs. 128×106 /ml), viability (22.6±10.6% vs. 37.1±26.1%), morphological normality (27.0±50.2% vs. 45.6±123.0%) of EE and AV groups were not significant different, but the post-thaw motility was significant lower in EE than that in AV group (53.1±3.6 vs. 73.6±5.7) (p<0.05). In conclusion, semen collection methods did not significant different between EE and AV groups except of post-thaw motility and so both semen collection methods could be applied in feline semen collection methods.

For the application of nano-sized material in various fields, the evaluation of nano-sized material toxicity is important. In the present study, various concentrations of 200 nm-sized silicon dioxide nanoparticle suspension were intraperitonially injected into mice to identify the toxicity of silicon dioxide nanoparticle in vivo. In the hematological analysis of group II treated with silicon dioxide nanoparticle 100 mg/kg body weight, lymphocytes and monocytes were significantly different compared to the control group. In group III treated with silicon dioxide nanoparticle 200 mg/kg body weight, lymphocytes, monocytes and hemoglobin were significantly different compared to the control group. In blood biochemical analysis of group III, the concentration of AST, ALT, BUN, and creatinine were significantly different compared to the control group. Histopathologic examination of the kidney indicated a mild injury only in mice received 200 mg/kg silicon dioxide nanoparticle. According to the results of the present study, the significant differences in the hematological and blood biochemical analyses and abnormal histopathological findings in the mouse kidney may have been related to exposure to silicon dioxide nanoparticle.

In the present study, the removal of Pb (II) ions on oxidized activated carbons (ACs) was investigated. ACs were derived from activation of indigenous cotton stalks waste with potassium hydroxide (KOH) in two-stage process. The KOH-ACs were subjected to liquid-phase oxidation with hot HNO3 and one untreated sample was included for comparison. The obtained carbons were characterized by Fourier transform infrared (FTIR), slurry pH and N2-adsorption at 77 K, respectively. Adsorption capacity of Pb (II) ions on the resultant carbons was determined by batch equilibrium experiments. The experimental results indicated that the oxidation with nitric acid was associated with a significant increase in mass of yield as well as a remarkable reduction in internal porosity as compared to the untreated carbon. The AC-800N revealed higher adsorption capacity than that of AC-800, although the former sample exhibited low surface area and micropore volume. It was observed that the adsorption capacity enhancement attributed to pore widening, the generation of oxygen functional groups and potassium containing compounds leading to cation-exchange on the carbon surface. These results show that the oxidized carbons represented prospective adsorbents for enhancing the removal of heavy metals from wastewater.

Canine heartworm disease is typically characterized by the presence of heartworms in the pulmonary artery and, to a lesser degree, the right ventricle. Systemic arterial dirofilariasis is an unusual manifestation of heartworm disease of dogs that results from aberrant migration of Dirofilaria immitis into the peripheral arterial circulation. A three-year-old Jindo dog was referred to the Veterinary Medical Center because of hindlimb lameness, paresthesia of hindlimbs, and interdigital ischemic necrosis. Angiography and ultrasonography were performed, resulting in diagnosis of heartworm infestation. In necropsy, entangled heartworms were present throughout the body, including lungs, kidney, small intestinal lumen, and arteries, in addition to the right ventricle and pulmonary artery. Histologically, lung showed adult heart worms in vessels, organized thrombotic vessels, and interstitial pneumonia featuring type II pneumocyte hyperplasia, thickened alveolar wall, and compressed alveolar spaces. Chronic parenchymal lesions, such as focal or diffuse necrosis, fibrosis, and dystrophic calcification were remarkable in liver and kidney. The current case showed a typical canine systemic heartworm disease caused by aberrant migration of Dirofilaria immitis.

We investigated free radical reactions in lung of living mice using an in vivo electron spin resonance (ESR) spectrometer and nitroxyl radical as a probe. When an aqueous solution of nitroxyl probe was trans-tracheally administered into lung of living mice, a sharp triplet signal was observed at the chest of the mice. The signal showed a gradual decrease with time, obeying first-order kinetics. Signal decay rates of carbamoyl-PROXYL and carboxy-2,2,6,6-tetramethyl-piperidine-N-oxyl were faster than those of CAT-1 and carboxy-PROXYL. The mechanism of signal decay may be attributed to (i) reaction with reactive oxygen species such as ·OH, (ii) transfer into blood circulation, or (iii) reduction by compounds continuously supplied. However, little is known about the clearance mechanism of the nitroxyl probe in lung. To evaluate the disappearance of the ESR signal of the nitroxyl probe in lung, in vivo ESR spectra in chest of mice was recorded after trans-tracheal administration of an aqueous high concentrate solution of nitroxyl probe. A broad signal from the chest was observed immediately after administration due to Heisenberg spin exchange interaction. A sharp triplet signal was superimposed on the broad signal and the appearance of a triplet signal was followed by disappearance of the broad one. Peak-to-peak line width of the sharp signal was almost the same as that after intravenous administration. A distinct signal was detected in blood collected 10 min after trans-tracheal administration of nitroxyl probe. The observations indicate the transfer from lung to blood circulation and its contribution to clearance of probe in lung. Appearance of a sharp signal in blood after trans-tracheal administration was dependent on the kind of nitroxyl probe, showing a different transfer rate from lung to blood.

Sepsis is a clinical syndrome defined as a systemic inflammatory response to infection. Eritoran is a synthetic lipid A derivative that competes with lipopolysaccharide in binding to the identical site of myeloid differentiation-2/toll-like receptor 4 complex. Eritoran is effective in decreasing the septic mortality of Gram-negative bacteria-infected animals. Eritoran has been highlighted as a candidate drug for treatment of endotoxemia in phase I clinical studies with healthy human volunteers. A phase II trial of eritoran has been conducted in patients with severe sepsis. Intravenous infusion of eritoran reduced the mortality rate, as compared with the placebo group, in sepsis patients at a high risk of mortality according to acute physiology and chronic health evaluation-II scores. A phase III study of eritoran was completed in 2011. The results appear to be disappointing as no statistically significant difference in all-cause mortality was observed between the eritoran treatment group and the placebo group on day 28 in sepsis patients with a high risk of death. In this review, we focus on the rationale for the use of eritoran in treatment of sepsis as well as its clinical applications.

La doped CuO-ZnO-Al2O3 powders are prepared by sol-gel method with aluminum isopropoxide and primarydistilled water as precursor and solvent. In this synthesized process, the obtained metal oxides caused the precursor such ascopper (II) nitrate hydrate and zinc (II) nitrate hexahydrate were added. To improve the surface areas of La doped CuO-ZnO-Al2O3 powder, sorbitan (z)-mono-9-octadecenoate (Span 80) was added. The synthesized powder was calcined at varioustemperatures. The dopant was found to affect the surface area and particle size of the mixed oxide, in conjunction with thecalcined temperature. The structural analysis and textual properties of the synthesized powder were measured with an X-rayDiffractometer (XRD), a Field-Emission Scanning Electron Microscope (FE-SEM), Bruner-Emmett-Teller surface analysis (BET),Thermogravimetry-Differential Thermal analysis (TG/DTA), 27Al solid state Nuclear Magnetic Resonance (NMR) and transforminfrared microspectroscopy (FT-IR). An increase of surface area with Span 80 was observed on La doped CuO-ZnO-Al2O3powders from 25m2/g to 41m2/g.

教育課程包括公共團體和各級學校為了達成國家制定的教育目的實行的所有計劃和活動。因此現場的教育內容範圍和水準與教育過程中設定的教育目標有關。漢語課也不例外。現在一線中學·高中的漢語課是按‘2007年改定漢語課教育課程’進行的。由於教科書按改定的教育過程次第編纂，到2010年現在為止，有些學年還不能使用按改定的教育過程編纂的教科書，所以經常造成混亂。本稿為了‘2007年改定漢語課教育課程’能順利適應現場，試論新教育課程中散文教育的特徵和高中<漢文Ⅱ>散文教育的方向。‘2007年改定漢語課教育課程’改變過去以‘漢字’和‘漢字語’為中心的教育，顯示了以‘漢文’為中心的明顯的方向性。與七次教育過程相比‘2007年改定漢語課教育課程’中的<漢文Ⅰ>和<漢文Ⅱ>的目標從解讀階段上升到了對漢文的理解與欣賞階段，要求學習各種各樣的漢文資料。並且提高對漢文學史的理解，更加強化了在'漢字文化圈'上作為文化教育的目標。‘2007年改定漢語課教育課程’旨向漢語閱讀能力的提高'，在這裡所說的閱讀能力不僅是解釋作品的能力，而是對作品的高層次的理解與鑒賞。所以‘2007年改定漢語課教育課程’中的散文教育應該以學會的內容為基礎，解讀文章，理解並鑒賞作品的內容與主題，應該超過純知識的層次，為了傳統文化的理解與繼承，為了漢字文化圈的相互理解與交流要做出貢獻。<漢文Ⅰ>和<漢文Ⅱ>要採取同樣的方式，但韓國漢文學作品應該考慮文學史的進程，對有關作品要達到賦予文學意義的水準。比起<漢文Ⅰ>來說，<漢文Ⅱ>應該選擇更高水準的文學作品，如果是文學作品，教育時要根據文學史的進程，培養理解與鑒賞有關作品的能力。這就是說，<漢文Ⅱ>是以先行學習為前提的課，所以定教育方向時比'閱讀'領域應該更加重視'理解'領域和文化領域。為了更有效的<漢文Ⅱ>散文教育，考慮了以下幾個方案。第一，解讀散文時可以採用傳統的散文分析法之一的篇章法。篇章法以含主題的文章為中心，結構化分析其他文章的有機連接，是一種尋主題與脈落的方法。解釋作品時，先簡單的解釋全作品後，讓學生們尋找作品的主題意義和敘述結構的話，比從頭到尾解釋的方法，能更有趣兒的進行講課。第二，對於漢文散文來說，語體不同，所表現的特徵和形式也會不同，因此理解與鑒賞散文時有必要強調語體教育。現在使用的<漢文古典>上也強調一些散文語體的特徵，但是只通過教科書裡的解釋不能完全理解‘序’的整體特徵和敘述方式。最好大略說明有關作品的語體特徵。第三，文學類散文要採用根據文學史進程來尋作品意義的方式。尤其是文學史上的重要作品和關於文學批評的內容。如果不懂文學史的進程，接觸文學類散文的話，儘管能轉換成我們國語，但不會理解其文章的意思。<漢文Ⅱ>的散文教育不僅要與別的科目有聯繫，而且實施時最好要擴大到文化教育的層次。漢文包括文·史·哲，<漢文Ⅱ>在內容選擇上比中學漢文1，2，3和高中<漢文Ⅰ>更自由。所以<漢文Ⅱ>的散文教育把編制的核心放在給學生們提供廣泛的視角和多種多樣的內容上。這樣不僅能擴展漢文水準，而且能提高對不同的漢文作品的理解能力。關於這個問題還可以考慮，把韓中日的類似主題散文編成一個單元來學習的方法。總的來說，按2007年改定敎育課程<漢文Ⅱ>的散文敎育方向，首先要把'漢文閱讀能力的提高'作為目標，但不能停止在閱讀階段，要培養理解與鑒賞能力，最好是擴大到文化教育的層次。

The aim of this study was to investigate what protein(s) of porcine epididymal fluid (pEF) are able to enhance the nuclear maturation of porcine germinal vesicle (GV) oocytes in vitro. Proteins of pEF were fractionated by affinity, ion exchange, and gel filtration chromatography. Porcine cumulus-oocytes complexes (COC) from follicles were cultured in tissue culture medium (TCM 199) containing various fractions obtained by chromatography. Porcine COCs were also cultured in TCM 199 containing various meiosis inhibitors and pEF. After 24 or 48 h culture, oocytes were examined for evidence of GV breakdown, metaphase I, anaphase-telophase I, and metaphase II. When porcine COCs were cultured in the medium with meiosis inhibitor such as, dibutyryl cAMP (dbcAMP) and forskolin (Fo), more than 80% of oocytes were unable to resume meiosis. However, porcine COCs supplemented with pEF were able to overcome the inhibitory effect of dbcAMP and Fo. Maturation rate of oocytes was significantly (p<0.05) increased in the media supplemented with cationic protein(s) during in vitro maturation than in those with anionic protein(s) (44.1% vs 20.0%). When oocytes were cultured in the TCM 199 with fractions obtained by gel filtration, the maturation rate of oocytes was significantly (p<0.05) higher in fraction 11 containing 18 kDa than other fractions. The present study suggests that 1) dbcAMP and Fo prevent the spontaneous maturation of oocyte after isolation from follicles, and that pEF contain a substance(s) that improves meiosis resumption in vitro of porcine COCs, 2) cationic 18 kDa protein(s) are responsible for promotion of MⅡ stage.

This study developed the pressure measurement monitoring system named VIP-2000 for monitoring a pressure of ullage space in cargo tank. VIP-2000 is designed in compliance with IMO(international maritime organization) SOLAS 74, Chap. II-2 Req. 59. IMO is providing the establishment of a pressure measurement equipment for secure the stability from vacuum or the overpressure that caused by in breakdown of the P/V valve. VIP-2000 operates the early warning of the visible and audibility in dangerous situation of cargo tank. In order to evaluate the performance of VIP-2000, the pressure measurement experiments have been conducted.

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most prevalent pathogens in hospitals. To investigate cross contamination by this bacterium in both dental and medical settings, the pathogens that cause acute pyogenic infection and one of the major microbes responsible for nosocomial infection were isolated from health care providers, nurses and patients. We used VITEK II to measure drug sensitivity, and we further performed biochemical testing, coagulase serotype testing and pulse-field gel electrophoresis (PFGE) for isolated MRSA colonies. The isolation rate of Staphylococcus aureus from nasal swabs was 75.0% from dental health care providers and 18.8% from the medical health care providers. A total of 10 MRSA strains were isolated from 40 health care providers and 2 patients and the prevalent coagulase serotype from patients and health care providers was VII. The antimicrobial drug resistance and partial PFGE types of the isolated MRSA strains showed a similar pattern. These results suggest that MRSA may be one of the principal causes of nosocomial infection in dental and medical hospitals.

제주도 월정 앞바다에서 건설 중인 4MW 해상풍력단지의 설계자료를 준비하기 위하여 측정-상관-예측(MCP)방법을 이용하여 단기간 풍황탑 자료로부터 장기간 풍황자료를 재생산하였다. 두 참조지점으로서 제주, 구좌 기상관측소와 선형회귀 MCP, 행렬 MCP 조합에 대한 정량적 오차분석을 실시한 결과 구좌와 행렬 MCP에 의한 장기간 보정이 가장 최선의 조합임을 도출하였다. 재생산된 풍황자료를 이용하여 월정해상 풍력발전기의 형식등급을 결정하기위한 표준난류모델 및 극한풍속모델 해석을 수행하였다. 50년 회귀주기의 10분-단위 극한풍속을 예측하기 위해 재생산된 8.5년의 월정 풍황을 검벨 분포로 해석하였다. 이에 의하여 결정된 풍력발전기 형식등급은 II A인 것으로 나타났다.

From a conversation-analytic perspective, this paper reports on the analysis of incey used as a discourse marker in spontaneous Korean conversations. Systematic attention is given to how it is used as an interactional resource for recalibrating a prior description and engaging the hearer to take the conjoined perspective grounded on the point of "here and now." It is shown that the sequences in which incey is embedded are characterized by a vivid description of an event/state of affairs or reported speech produced in the manner of having the target event/state of affairs reenacted. Such a formulation, often signaling a shift toward an expressive mode of telling, provides a context where the hearer is invited to be involved in the detailed description of the event/state of affairs (i.e., from the shared perspective) and to appreciate its upshot by co-taking the speaker’s vintage point. Such a shift is often observed in terms of managing the boundary-marking as well, e.g., usually practiced in the form of marking contrast or mediating self-repair through which a prior turn component is progressively replaced by another. Some of the crucial implications of these practices are noted in terms of (i) the preliminary nature of incey-prefaced talk, i.e., the tendency of incey to preface materials which are still prefatory to what is to be told further later, and (ii) the ordinary nature of incey-prefaced talk which the co-participants tend to orient to as being empirically grounded and/or commonsensically accessible.

◉ 목적: 본 연구의 목적은 다감각 자극이 지적장애 아동의 문제행동 빈도수에 미치는 효과와 지속여부를 알아보는 것이다. ◉ 연구방법: 본 연구는 문제행동이 나타나는 지적장애 아동 4명을 대상으로 다감각 자극을 중재하였다. 아동의 인지기능 평가를 위해 기초선과 유지기에LOTCA-II를 시행하였다. 개별실험 연구방법(single subject experiment research design) 중 대상자간 중다기초선설계(multiple-baseline across subjects)의 ABA'를 사용하였다. 연구는 기초선, 중재기, 유지기에 걸쳐 총 14회 동안 이루어졌으며 각 회기는 30분씩 시행되었다. 문제행동 빈도수는 20분 동안 측정되었다. ◉ 결과: 본 연구 결과 대상자 1의 평균 문제행동 빈도수는 기초선과 비교하여 다감각 자극 중재기 동안 증가하였으나, 대상자 2, 대상자 3, 대상자 4의 중재기 동안 평균 문제행동 빈도수는 감소하였다. 대상자 1, 대상자 3, 대상자 4의 유지기 동안 문제행동은 중재기 보다 증가하였으나, 대상자 2는 감소하였다. 기초선과 비교하여 유지기 동안 대상자 1의 문제행동은 증가하였으나, 대상자 2의 문제행동 빈도수는 감소하였다. 대상자 3과 대상자 4의 평균 문제행동 빈도수는 차이가 나타나지 않았다. ◉ 결론: 본 연구는 다감각 자극이 지적장애인의 문제 행동을 감소시키는 치료적 효과를 보였다. 대상자 2는 기초 선과 중재기보다 유지기에 더 많은 감소를 나타냈으나 대상자 1, 대상자 3, 대상자 4는 지속적인 효과가 나타나지 않았다.

본 연구의 목적은 고등학교 교육과정에서 사용되고 있는 지구과학 불일치 용어를 조사하고 그 대안을 탐색하는 데 있다. 고등학교 지구과학 교과서에서 같은 의미를 지니면서 다른 용어를 사용하는 경우 이를 불일치 용어로 정의하였다. 불일치 용어를 참고문헌과 선행 연구의 용어와 비교한 후, 284명의 교사와 학생을 대상으로 선호도를 조사하였다. 연구 결과 불일치 용어는 고등학교 교과서는 물론 참고문헌에서도 다수 조사되었다. 선호도 조사 결과 의미가 쉽게 전달될 수 있는 용어, 이전에 학습한 용어, 외래어 표기법에 맞는 용어에 대한 선호도가 높았다. 그리고 고유명의 표기가 다르거나 서로 다른 문헌과 배경 지식에 기반하고 있는 불일치 용어는 외래어 표기법과 학회 발간물에 근거하여 대안을 모색할 수 있다. 따라서 공인된 이론에 근거하고 의미 전달이 쉬운 지구과학 용어를 공유하여 사용함으로써 혼란을 해소할 수 있을 것이다.
