This paper investigates student responses to CBLI(Content-Based Language Instruction), considered to be a prerequisite for CBI(Content-based instruction) in EFL situations. Even though a growing number of Korean universities have implemented CBI, English-medium instructions are criticized and lead to a number of issues. Straight(1997) divided CBI into CBLI focusing on language teaching and CBCI(Content-Based Content Instruction) focusing on subject matter. Seo(2010) suggested a modified version of CBI and contended CBLI should precede CBCI in order for students to be prepared for CBI. To lower students' affective filter, instruction was delivered in Korean in CBLI, but students received language input from authentic materials. Based on Seo's(2010) suggestions, an experimental class was conducted with 3 university students using the script of Desperate Housewives(2006) as study material. The teacher encouraged students to the content and avoided linguistic explanation as much as possible. The results and implications were as follows: first, CBI ought to be modified in EFL contexts because students seem to be obsessed by language learning where content learning should be a primary concern; second, it is necessary to enlighten students to the fact that a primary concern of content is related to language development; third, teachers need to monitor students frequently so that they maintain their interest in the content.

본 연구는 부존 조사료자원 이용으로 수입사료를 줄이고 사료비를 절감하고자 2010년도에 전남 해남(간척지), 강원 평창(강변), 원주(섬강변), 전남 영광(와탄강변) 등 4개 지역에서 갈대와 억새 등 야초 자생지를 탐색하고, 수확·이용실태 조사와 함께 사료가치를 분석하였다. 전남 해남 해남목장 내 갈대(Phragmites communis) 위주의 야초 자생지는 300 ha로 예년에는 2회 곤포작업하여 연간 사일리지로 2,300~2,500톤(ha당 8톤)을 생산하였으나 2010년도는 1회 곤포조제로 사일리지 2,000톤(ha당 7톤)을 생산하였다. 유통가격은 롤 당 53천원으로 ㎏당 110원이었다. 곤포는 전량 자가소비하며, 외부 작업단에 롤 당 26천원의 작업비를 지불하였다. 연간 조수입은 2억 2,260만원이며, 소득은 1억원 수준(345천원/ha)이었다. 초장 150 ㎝의 갈대는 조단백질 8.4%, 상대사료가치 71.9 (건초 5등급), 건물 소화율 60.1%로 사료가치는 볏짚에 비해 약간 나은 것으로 평가되었다. 갈대 사일리지의 사료가치와 유기산 함량은 동일 지역에서 동일한 재료로 사일리지를 조제하더라도 수확시기에 따라 차이가 컸으며(CP 4.7~6.4%, RFV 62.2~78.9, 건물 소화율 41.9~53.9%), 갈대 사일리지의 품질은 수단그라스에 비해 불량하였다. 강원 평창 강변 자생갈대의 사료가치는 초장이 79, 117, 121, 142㎝로 생육이 진행됨에 따라 낮아져, 조단백질은 각각 13.9%에서 7.6%로, 상대사료가치는 90.7 (건초 3등급)에서 76.1 (건초 4등급)로, 건물 소화율은 72.9%에서 54.7%로 감소하였다. 원주 섬강 주변 야초류는 곤포수확 작업에 어려움이 있었으며, 초장 130 cm의 갈대는 조단백질 8.5%, 상대사료가치 82.3 (건초 4등급), 건물 소화율 70.2%로 사료가치는 높았으며, 220㎝의 성숙한 갈대는 조단백질 10.2%, 상대사료가치 65.1 (건초 5등급), 건물 소화율 48.9%로 볏짚 대비 조금 나은 것으로 평가되었다. 전남영광지역에서는 와탄천 주변에 자생하는 갈대를 수거 이용하고자 시도하였으나 경제성이 없어 중단하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거·이용하되, 사료가치를 유지하고 가축 기호성이 양호한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전(늦어도 7월까지)에 수확·이용하는 것이 권장된다. This study was carried out in 2010 to investigate the utilization and forage quality of native grasses, such as Phragmites communis which might reduce the cost of feeding domestic cattle. The regions surveyed were the Haenam ranch in Haenam, Pyeongchang, Wonju, and Yeonggwang. In Haenam, yearly silage production harvested from 300 ha was 2,000 MT (7 MT/ha). All of those round bale silages were self-consumed in that region, and marketing price was 50,000 55,000 won per roll (110 won/㎏). Phragmites communis of 150 ㎝ in length contained 8.4% crude protein (CP) with relative feed value (RFV) 71.9 and 60.1% in vitro dry matter digestibility (IVDMD), which was somewhat more favorable than forage quality of rice straw. The silage quality of Phragmites communis varied greatly by the time of harvest (CP 4.7 6.4%, RFV 62.2 78.9, and IVDMD 41.9 53.9%), even with the same district and of the same original forage materials. Generally, the quality of Phragmites communis silage of was poorer than that of sorghum * sudangrass hybrid. In Pyeongchang, forage quality of Phragmites communis was decreased from 13.9% to 7.6% in CP, 90.7 to 76.1 in RFV, and 72.9% to 54.7% in IVDMD, as plant was getting mature, from 79 ㎝ to 117 ㎝, 121 ㎝ or to 142 ㎝ in length. In Wonju, the quality values of Phragmites communis of 130 ㎝ in length were 8.5% CP, 82.3 RFV and 70.2% IVDMD, while those of matured grasses of 220 ㎝ in length were lower (10.2% CP, 65.1 RFV and 48.9% IVDMD), but this was a little more favorable than quality of rice straw. In Yeonggwang, feeding Phragmites communis was tried in a Hanwoo feed, but stopped due to low profitability. In conclusion, the overall quality of most native grasses including Phragmites communis in this survey was poor. Therefore, we recommend that Phragmites communis and native grasses should be harvested on June or July to obtain richer forage quality in forage values than rice straw.

급격한 고령화 사회로의 진입과 서구화된 식습관에 의해 협심증, 심근경색증, 고혈압 등에 의한 심장질환자의 수가 5년간 10만명 이상 증가했다. 심장질환은 지난 8년간 꾸준히 국내 사망원인 2위를 기록 중이며, 이로 인해 연간 소모되는 의료비는 6조원에 달한다. 증가한 환자와 함께 다양한 치료법이 제시되고 있는 가운데, 현재 보편화 된 관상동맥 중재시술 중 스텐트 삽입술의 단점인 재협착이나 장기간 이중항혈소판제 복용으로 인한 출혈의 위험 증가 등의 문제점을 보완하기 위해 약물코팅풍선카테터가 개발되어 점차 상용화되고 있는데, 국내에선 2010년 ‘SeQuent Please^Ⓡ (비브라운코리아)’라는 제품이 처음 출시되면서 약물코팅풍선카테터를 사용한 시술이 시작되었고, 이후 2012년 보험급여가 적용되면서 그 사용량이 본격적으로 늘어났다. 약물코팅풍선치료는 국내뿐만 아니라 전 세계적으로 사용이 증가하고 있는데, 특히 일본을 포함한 아시아태평양 지역에서 그 사용량이 급격히 증가하고 있다. 현재까지 국산 제품의 수요가 증가하고 있는 상황이며 향후, 동물시험 및 임상시험에서의 성능이 입증된다면 위험성이 높은 스텐트 삽입술에 비해 효과적인 시술이 될 것이라 예상한다. As a result of the rapid entry into an aging society and westernized eating habits, the number of heart disease patients caused by angina pectoris, myocardial infarction, and high blood pressure has increased by more than 100,000 over five years. Heart disease has consistently ranked second in the cause of death in Korea over the past eight years, and medical expenses consumed annually reach 6 trillion won. While various treatments are being proposed for more patients, drug-coated balloon catheters have been developed and gradually commercialized to solve the disadvantages of stent implantation such as restenosis and increased risk of bleeding due to long-term double antiplatelet medication. In Korea, it began to use a drug-coated balloon catheter with the first release of it called “SeQuent Please^Ⓡ (Bibrown Korea)” in 2010. Its demand increased gradually as insurance benefits were applied in 2012. Drug-coated balloon angioplasty is increasing in use not only in Korea but also around the world, especially in the Asia-Pacific region, including Japan. Until now, the demand for domestic products is increasing, and if the efficiency in vivo and clinical trials is proven in the future, it is expected to be an effective procedure compared to high-risk stent implantation.

Interfacial Tension and Contact Angle Variations of SUS304 Melt in Contact with Solid Oxides and CaO - SiO2 - Al2O3 (CaF2) Slags at 1470℃

Kim, Dong Sik,SEO, Sung Mo,PAIK, Young Hyun,LEE, Won Pyo 대한금속재료학회(대한금속학회) 1996 METALS AND MATERIALS International Vol.2 No.2

Study on the interfacial properties of SUS304 melt in contact with pedestal oxides and also liquid slugs of varying chemistry was carried out by using a combination of the sessile drop method and a X-ray fluoroscopic technique at 1470℃. Interfacial tension and contact angle were obtained directly from a numerical solution of the Young-Laplace equation. Surface tension of SUS304 was found to be 1467 mN/m in Ar-atmosphere which was considerably lower than that of pure iron. This may be due to the existence of surface active elements such as Cr, Ni and Mn etc. in SUS304. Interfacial tensions of SUS304 in contact with CaO-SiO₂-Al₂O₃(CaF₂) slugs were in the range of 925 to 1148 mN/m. The contact angle between SUS304 and various pedestal was about 120° regardless of pedestal oxides, Al₂O₃, TiO₂ and SiO₂. Contact angles between SUS304 and the pedestal alumina coexisting with liquid CaO-SiO₂-Al₂O₃(CaF₂) were in the range of 125° to 142°.

( In Hyuk Kwon ),( Dae Yeon Kim ),( Dong Won Lee ),( Tae Hyung Ryu ),( Jae Eun Choi ),( Soo Hong Seo ),( Young Chul Kye ),( Hyo Hyun Ahn ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Self-healing juvenile cutaneous mucinosis is a very rare, self-limiting disease characterized by transient cutaneous lesions that affects the young. This disorder is characterized by rapid onset of asymptomatic papules and nodules on the face, periarticular regions, abdomen, and thigh. As implied by the name, the lesions spontaneously resolve over weeks to months. In contrast to mucinoses affecting adults, Self-healing juvenile cutaneous mucinosis has not been associated with systemic disorders such as paraproteinemia, bone marrow plasmacytosis, or thyroid diseases. A 7-year-old male presented with erythematous papules, multiple subcutaneous nodules on trunk and both arms that began 6 days before. Aside from pruritus of lesions no other symptoms were manifested. Histopathology showed microabscess in epidermis, superficial perivascular lymphocytic infiltration, and mucin deposition in dermis On follow up visit, although new lesions were present, previous lesions were subsiding. In consideration of the clinicopathological features, the diagnosis of self-healing juvenile cutaneous mucinosis was made. The patient is under close observation with no specific treatment. Herein, we report a rare case of self-healing juvenile cutaneous mucinosis. Knowledge of this entity may prevent unnecessary diagnostic testing and aggressive treatment in the pediatric population with this self-limited disease.

Objectives: The aim of this study is (1) to investigate the historic changes and pharmacological efficacies of Woohwangchungsim-won and (2) to discuss the necessities for Woohwangchungsim-won's clinical applications. Methods: This study was performed through (1) investigating the ancient literature records related with Woohwangchungsim-won and analyzing Woohwangchungsim-won's composition, dosage and indications, (2) searching articles about Woohwangchungsim-won on 10 major Korean web and 3 major foreign web article search engines and analyzing Woohwangchungsim-won's pharmacological efficacies and indications. Results: Woohwangchungsim-wom has been used for cerebrovascular diseases such as stroke and palpitation. Also, there are some ancient literature records of Woohwangchungsim-won's clinical applications in neuropsychiatric disorders such as depression and bipolar disorder. In addition, there have been a number of experimental studies which demonstrate Woohwangchungsim-won's neuroprotective effect on cerebral cortex and hippocampus injury. So, it is possible to infer that Woohwangchungsim-won can be used for the treatments of neuropsychiatric disorders associated with neuronal cell death in cerebral cortex and hippocampus. But there have been no or less experimental studies which demonstrate the pharmacological efficacy of Woohwangchungsim-won on such disease. Conclusion: It is necessary that further experimental studies which demonstrate Woohwangchungsim-won's pharmacological efficacy on neuropsychiatric disorders should be done and Woohwangchungsim-won's clinical applications should be expanded on the basis of those related experimental results.

Young Eun Park,Ji Hong Cho,Hyun Mook Cho,Jung Yun Yi,Hyo Won Seo,Young Gyu Lee,Yul Kyun Ahn,Hyung Ki Lim,Hyun Sook Kim,Seong Jin Choi 한국육종학회 2007 한국육종학회지 Vol.39 No.3

‘Seohong’ was bred within the potato breeding program of National Institute of Highland Agriculture (NIHA). It was originated from a cross made in 1997 between ‘Jashim’ as a female and 93K65-1 as a male parent. Seohong was evaluated as a seedling number 97S05-1 for tuber characteristics, growth and yielding ability from 2001 to 2002, and than this clone was renamed as Daegwan 1-82. This clone was evaluated in the regional yield trial and the disease resistance in the five locations for three years. Finally, this clone was named as ‘Seohong’ and registered a new recommended potato cultivar in 2006. This cultivar has a round, shallow eye depth, light red-skinned tuber characteristics and low to medium dry matter content. It showed high resistance to common scab (Streptomyces scabies) and potato leaf roll virus (PLRV), however it was susceptible to potato virus Y (PVY) and late blight (Phytophthora infestans). Its mean tuber yields from the regional yield trial and winter cropping trial were 12 and 49 percent higher than that of ‘Superior’, respectively.

Seo, Yu-Kwang,Kim, Young-Wook,Nishimura, Toshiyuki,Seo, Won-Seon Elsevier 2016 Journal of the European Ceramic Society Vol.36 No.15

<P><B>Abstract</B></P> <P>The high-temperature strength of a thermally conductive SiC ceramic sintered with 1vol% equimolar Y<SUB>2</SUB>O<SUB>3</SUB>–Sc<SUB>2</SUB>O<SUB>3</SUB> additives (thermal conductivity=234W (mK)<SUP>−1</SUP>) was investigated at temperatures up to 1800°C. Observation of the ceramic using high resolution transmission electron microscopy (HRTEM) exhibited both clean and crystallized SiC/SiC boundaries, as well as clean SiC/junction phase boundaries with a fully crystallized junction phase. No microstructural or polytype changes after flexural testing at 1800°C were observed using scanning electron microscopy and phase analysis with the Rietveld method. The ceramic maintained 93% of its room temperature (RT) strength up to 1600°C, and showed rapid degradation at 1700°C and 1800°C. Degradation at temperatures above 1600°C was due to softening of the grain boundary phase, as evidenced by the nonlinear behavior of load-displacement curves. Flexural strengths of the highly thermally conductive SiC ceramic at RT and 1800°C were 536MPa and 345MPa, respectively.</P>
