최근 의학교육에서는 문제중심학습의 성공 요인 중의 하나로 학습자가 평가한 튜터 역할의 중요성이 부각되고 있다. 이에 본 연구에서는 학습자가 평가한 튜터의 역할이 개인과 그룹 차원에서의 상호작용 및 학습결과와 의미 있는 관계를 형성하는지를 확인하고자 하였다. 정교화 촉진, 학습과정 감독, 지식 통합, 상호작용 촉진을 포함한 네 가지가 본 연구에서 사용한 튜터 역할의 특성이었고, 상호작용은 개인의 내향중심성 정도와 외향중심성 정도 그리고 그룹의 상호작용 밀도를 사회연결망 분석도구를 사용하여 측정하였다. 학습결과는 학업성취도, 참여도, 학습자 만족도를 개별로 측정하고, 그룹에 속한 개인 점수의 합을 그룹 학습결과로 사용하였다. 연구대상은 3주 동안 의과대학 ‘기초 PBL’수업을 수강한 6개 그룹 42명의 학생들과 6명의 튜터가 포함되었다. 연구 결과, 튜터의 상호작용 촉진 역할은 개인의 내향중심성(F(1, 40) = 9.924, p < .01)과 외향중심성(F(1, 40) = 17.264, p = .001)을 모두 유의미하게 예측하는 것으로 나타났으며, 개인의 외향중심성은 나아가 학업성취도(F(1, 40) = 9.374, p < .01)와 참여도(F(1, 40) = 12.019, p < .01)를 유의미하게 예측하는 것으로 나타났다. 한편, 그룹 차원에서 분석된 튜터의 학습과정 감독, 지식 통합, 상호작용 촉진 역할과 그룹 상호작용의 밀도 그리고 학습결과 간의 유의미한 관계는 PBL에서 그룹 활동 활성화를 위한 튜터 역할의 중요성을 다시 한 번 인식하게 해주었다. The purpose of the study was to investigate the effects of learners' perceived roles of a tutor on interactions and learning outcomes in a Problem-Based Learning(PBL). This study was conducted with six groups of students(forty-two students) enrolled in a PBL class and six tutors at a medical university in Korea. To measure the learners' interaction we have used in-centrality, out-centrality and density. We also have conducted a survey to identify the roles of a tutor. For learning outcomes, achievement, participation, and learners' satisfaction were used for analysis. Results indicated that the ‘stimulating interaction’ role of a tutor significantly predicted learners' in-centrality and out-centrality. The learners' out-centrality significantly predicted individuals' achievement and participation. On the other hand, at the group level, ‘directing the learning process’, ‘stimulating integration of knowledge’, and ‘stimulating interaction’ role of a tutor had a positive correlation with the density, and the density had a positive correlation with the group learning outcome

In these days, Korea has undergone various changes in every social aspect throughthe process of modernization. Especially in instituional and actual aspects, the family.and marriage have been changed greatly by the rapid urbanization and iudustrializatton,.and these changes have been investigated scientifically. This paper presents marital consciousness and actual behavior of 300 woman collegestudents in Daegu, and was surveyed comparing various parts-the humanities, natural·science and the arts. As for the basic attitude of marriage, they were positive in the need of marriage,,defined marriage as the second starting point of life. Also they put the aim of marriage,on mental value. As for the dating and purity before marriage, 84 percent of respondents assented tothe dating before marriage. And they thought it proper that the duration of datingwas one year to two years. The age of the first dating and the standard of sex moralstore significant. The part of the arts tended to be open, and the part of natural sciencewere conservative. As for the standard of spouse's choice, 84 percent of respondents wanted to have theright of priority they could choose their spouses for themselves. And they thought it·proper that the age of marriage was 25-year-old to 26-year-old, and the gap of maritalage was one year to three years. Ideal spouse's characteristic, home surroundings, and marital harmony were significant. Among various marital conditions, personality tended to to emphasized, and theatmosphere of family and masculine appearance were taken serious. As for a. spouses's job, professor or research occupation was popular. Compared withthe part of the arts, the part of the humanities and natural science were positive inpredicting marital harmony. Among various marital conditions, an only son, the eldest son, and an offspring ofa concubine tended to be evaded. The type of an ideal spouse was companionship.

강현주,김화영,조순영 강릉대학교동해안지역연구소 1999 東海岸硏究 Vol.9 No.2

For the purpose of quality improvement of potatoes produced in Kangwon-Do, the contents of protein, reducing sugar, and total phenolic compounds were determined for the dihaploid potato clones derived from cultivated tetraploid potato varieties. In addition, the analysis of lipoxygenase isozyme activities was carried out. Among 12 different dihaploid potato clones, the HAT-19 clone showed the highest protein content, and the content was much higher than those of the cultivated tetraploid potato varieties. HAT-19 also had the lowest reducing-sugar content when compared with other dihaploid clones. Lipoxygenase-2 activity had no high intensity in the tested dihaploid clones. On the other hand, the HIC-68 clone had the highest content of the total phenolic compounds among the tested dihaploid clones. The results suggest that the selected dihaploid clones should be useful for breeding potato varieties with good processign qualities.

강상목,정영근,조주현 한국환경경제학회 한국자원경제학회 2005 자원·환경경제연구 Vol.14 No.1

본 연구의 목적은 한국의 24개 광업과 제조업종을 대상으로 1995~1999년간 통합된 오염원단위 지수와 변화지수를 제시하고 이를 통하여 환경성과를 측정하고자 함이다. 본 연구는 오염원단위의 새로운 정의와 통합된 오염원단위를 측정하는 새로운 기법을 제시한다. 광업과 제조업을 경공업, 중공업 그리고 중공업내 오염산업과 여타중공업으로 구분하고 실증적으로 통합원단위 지수와 변화지수를 계측한다. 통합오염원단위 지수 기준으로 중공업내 오염산업은 가장 오염집약적인 업종인 반면, 같은 중공업내 여타 중공업에 속한 업종은 가장 오염저감에 성공적이다. 통합오염원단위 변화지수를 기준으로 산업 전체의 평균치는 1,091로서 오염배출량변화지수가 1.133으로 연간 13.3% 증가한 반면 산출량변화지수는 1.039로 연간 3.9% 증가하여 약 9.1% 상승하였다. 경공업과 중공업의 통합원 단위 변화지수는 각각 1.125와 1.042였고, 오염산업의 평균이 1.287로 가장 높았음에도 중공업의 평균이 낮았던 것은 역시 여타 중공업의 평균이 0.9)3으로 연간 약 9% 가량 감소하였기 때문이다. This paper measures integrated pollution intensities and changes in pollution intensity, and figure out environmental performance. We introduce a new definition of pollution intensity and its method measuring integrated pollution intensities. We distinguish 24 manufacturing industries into light industry and heavy industry, and divide heavy industry into pollution industry and the other residual heavy industry to measure the integrated pollution intensities and their changes. While the pollution industry within heavy industry, based on the integrated pollution intensity, was the most pollution-intensive, the other residual heavy industry within the heavy industry was the most successive in reducing pollutants. The annualized average index of the integrated pollution intensities grew as much as 9.1 percent, of which the annualized change in the index of pollution emission increased 13.3 percent, but the improvement of 3.9 percent in the change of output quantity offset the increase in the index of pollution emission. The changes in the integrated pollution intensity for the light and heavy industries were 1.125 and 1.042, respectively. The reason the heavy industry showed the lower change in the index of pollution intensity, while the change in the pollution industry was very high, was because the average change in the other heavy industry decreased around 9 percent.

The purpose of this study was to analyze risk of falls between elderly people and college students. The subjects of this study were 25 people aged 70 years or older and 17 college students located in Asan. We measured sensory, integrated balance, nervous, musculoskeletal system and HQR by FRA system (Inbody, Korea). The results of measurement showed significant differences in sensory system (p<.01), integrated balance (p<.001), nervous system (p<.001), and musculoskeletal system (p<.001) between groups. These results suggest that aging makes difference of function of these systems. In our view, counterplans need to be implemented, including exercise intervention to prevent decreases of fall risk,

에러가 없는 제곱근기와 대역제한필터를 사용한 SECAM Video Decoder를 위한 색상 및 밝기 신호의 복원장치

하주영,김주현,강봉순 東亞大學校附設情報技術硏究所 2005 情報技術硏究所論文誌 Vol.12 No.2

In this paper, we propose the SECAM video decoder system using error-free square root and band pass filter (BPF). SECAM uses frequency modulation (FM) to transmit the Db and Dr color difference information, with each component having its own subcarrier, so input signal of decoder, CVBS, has various frequencies whose bandwidth is 6.0 MHz. The proposed SECAM decoder uses two differentiators, trigonometric functions and as error-free square root to demodulate color information in chrominance processing. The BPF in decoder is used for removing color noise in chrominance and dividing CVBS into chrominance and luminance. The proposed system is experimentally demonstrated with Altera FPGA APEX20K1000EBC652-3 and TV-card available for SCEAM.

요조건하 몇가지 항생제에 대한 Postantibiotic Effect의 비교

배현주,최강원 대한화학요법학회 1990 대한화학요법학회지 Vol.8 No.2

The postantibiotic effect is defiend as suppression of bacterial growth that perisists after exposure of organisms to antimicrobial agents. Its clinical significance lies in impact on the frequency of antimicrobial administration. In lower urinary tract infection, single or short course therapy eliminates infection in most cases and the antibiotics used commonly were trimethoprim-sulfamethoxazole, amoxicillin, and ciprofiozacin. In this study minimal inhibitory concentraion and postantibiotic effect were tested in two conditions, Mueller Hinton broth at pH 7.4 with Mg concentration of 1.5mM and Mueller Hinton broth at pH 5.5 with Mg concentration of 8mM. PAE of S. aureus observed were 1.3 hours with amoxicillin, 0.7 hours with trimethoprim-sulfamethoxazole, 0.4 hours with ciprofloxacin in MHB at pH 5.5 with Mg concentration of 8mM and were not different from that in MHB at pH 7.4 with Mg concentration of 1.5mM. PAE of S. fecalis were 0.7 hours with amoxicillin, 0.6 hours with trimethoprim-sulfamethoxazole, 0.7 hours with ciprofloxacin. PAE of E. eoli were 0 hours with amoxicillin, 0.4 hours with trimethoprim-sulfamehoxazole, 2 hours with ciprofloxacin. PAE of K. pneumoniae and P. aeruginosa with ciprofloxacin were 1.25 hours and 1.5 hours and were similar to PAE in MHB at pH 7.4 with Mg concentration of 1.5mM.

송주현,정진영,강용구,이한용,손문익,서상일 대한골절학회 2003 대한골절학회지 Vol.16 No.3

목적: 골종양 환자나 외상, 골수염, 인공관절 치환술 등의 환자 등의 환자 치료에 많이 사용하는 장관골의 동종 이식에 대한 PRP (Platelet-Rich Plasma)의 효과를 토끼를 이용한 실험으로 알아보고자 하였다. 대상 및 방법: 20마리의 토끼를 대상으로 각각에 일련번호를 붙이고, 각 토끼의 양측 척골에 약 2㎝ 길이의 골편을 얻어 장관골 결손을 만들고 동시에 동종 장관골을 얻어, 홀수 토끼의 척골 골편을 짝수 토끼의 골결손 분위에 이식하고, 반대로 짝수 토끼의 척골 골편을 홀수 토끼의 골결손 분위에 이식하였다. 그 후 각 토끼의 좌측 척골 이식 부위에는 아무런 처치를 하지 않고 대조군으로 삼고, 우측 척골 이식부에는 PRP 0.7cc를 처치하여 실험군으로 삼았다. 술 후 0, 4, 8, 12주에 골이식부에 대한 방사선 촬영을 통하여 골유합 성적을 평가 비교하였다. 결과: 실험군의 척골 분절 결손부에서는 대조군에서보다 동종 분절골 이식부의 골유합이 방사선학적으로 향상된 것을 관찰 할 수 있었다. 결론: 동종 장관골 분절 이식시 PRP를 병용하여 사용할 경우 더욱 효과적인 신생조직 형성을 유도할 수 있으며, 임상에도 유용하게 적용할 수 있으리라 사료된다. Purpose: The purpose of this study was to evaluate the effect of Platelet-Rich Plasma(PRP) on the healing of the allograft for the treatment of the segmental bone defect of the ulna in Rabbits. Materials and Methods: About 2 ㎝-sized segmental bone defects were created on both ulna of twenty rabbits. The rabbits were divided into two groups, even and odd number groups after numbering them from 1 to 20. The segmental bone from the odd numbered animal was transplanted to the even numbered animal, and the even numbered to the odd numbered. The left side of the ulna was grafted with a segmental allograft only. The right side of the ulna was grafted with a segmental allograft and 0.7cc of PRP. Radiographs obtained at 0, 4, 8, and 12 weeks postoperatively were graded for radiologic union. Result: The use of the combination of PRP and segmental allograft demonstrated improved healing on radiographic study compared with that demonstrated after use of allograft alone. Conclusion: The results of the study suggests that the use of the combination of PRP and segmental allograft can be considered as an alternative method to manage the segmental defect of the long bone.
