본 논문에서는 진단에 중요한 정보를 가진 영역에 대해서 무손실 부호화하고 나머지 영역에 대해서는 손실 부호화를 하여 비트를 효율적으로 할당하는 MRI 영상 압축 방법을 제안한다. 제안한 방법에서는 척추 디스크 질환 인식을 위해 촬영된 MRI 영상을 대상으로, 질환의 특성을 이용하여 중요한 객체가 포함된 부분을 인식한다. 인식된 부분은 의사의 디스크 질환 유, 무의 판단에 중요한 부분이므로 무손실 부호화하고 나머지 부분은 손실 부호화하여 전송한다. 또한 손실 부호화하는 영역에 대해서 웨이브릿 변환 영역에서의 프랙탈 압축 방법을 적용하여 블록화 현상이 제거된 선명한 화질을 유지한다. In this paper, a MRI image compression technique, which allocates bits effectively by using lossless coding for region having important infommtion to decide disease and lossy coding for the rest, is proposed. In the proposed method, for MHI images needed to rccognize disk disease, we recognizc region having important objects by using the characteristics of c1isease. As the recognized region is imrxlrtant to decide whether disease exists or not, it is compressed by lossless coding and the rest is compressed by lossy coding, Also for the region compressed by lossy coding, we can obtain fine reconstructed images without blocking effect by adopting fractal coding in wavelet transform domain.

The purpose of this study is to measure pregnant women bodies around pregnant month, whose month undergoes physical alterations on their body shapes, and to reveal their physical characteristics by comparing the measurements. Thirty one women from three to fifth month were measured using Martin`s anthropometric instrument on 49 items. The measures were analyzed statistically. The statistical analyses used in this study was SPSS. This study results are summarized as follows. The items which showed a remarkable increase were bust width, under bust width, bust depth under bust depth, sitting waist depth, sitting omphalion depth, bust girth, under bust girth, waist girth, sitting waist girth, sitting omphalion girth. The anterior part of waist and abdominal sections projected forward gradually, so remarkably as to become to look like a round, at fifth month. Pregnant women change special alteration, which is depends on period of the pregnancy in physical phase. The early period of pregnancy, which is from first month to 3 months, do not show significant alteration. However, pregnant woman`s body has been changed in the half period of pregnancy, which is from 4 to 5 months. Accordingly, management of Maternity has been increased after 5 months period of pregnancy, which period reveals information about physical alteration of pregnant woman`s body shape.

본 연구는 대학생의 진로결정에 영향을 미치는 요인을 확인하기 위한 것이다. 이를 위해 서울, 경기도, 충청도에 소재한 4년제 대학에 재학 중인 대학생 673명에게 진로결정 여부와 진로 관련 변인들의 영향에 관한 설문을 실시하고 이를 분석하였다. 주요 연구결과는 다음과 같다. 첫째, 진로결정 집단과 진로미결정집단 간의 차이를 확인하기 위해 집단 간 차이 검증을 실시하였는데, 그 결과 성별은 집단 간에 유의미한 차이를 가져오는 변인이 아니었다. 둘째, 진로결정에 영향을 미치는 변인들의 효과를 분석하기 위해 로지스틱 회귀분석을 실시하였는데, 학년, 전공만족도, 진로개발역량은 대학생의 진로결정에 유의미한 영향을 미치는 변인이었으나, 학업성취도, 대학생활적응, 진로적응성는 유의미한 영향을 미치는 변인이 아니었다. 그 효과를 구체적으로 살펴보면 고학년이 저학년보다 진로를 결정할 확률이 2배 이상 컸으며, 전공만족도가 1단위 증가하는 경우 진로를 결정할 확률이 1.9배 커졌고 진로개발역량이 1단위 증가하는 경우 진로를 결정할 확률이 5.1배 커졌다. 이러한 결과들은 대학생의 진로결정을 지원하기 위해서는 학생들의 전공만족도를 높이고 진로개발역량을 증진 시킬 필요가 있음을 시사한다. The purpose of this study is to identify factors influencing college students`career decision. For this purpose, 673 college students in four - year colleges in Seoul, Gyeonggi- do, and Chungcheong - do were surveyed and analyzed. The main results are as follows. First, sexes did not show significant difference between career decision group and career indecision group. Second, logistic regression analysis was conducted to analyze the effects of variables affecting career decision. Grade, major satisfaction, and career development competencies were variables that had a significant effect on career decision of college students. However, academic achievement, college students’ adjustment, and career adaptability were not significant variables. These results suggest that in order to support career decision of college students, it is necessary to increase students majors satisfaction and improve career development capability.

經部固定 headgear 使用時 顔面頭蓋骨의 變位에 關한 張力計測法 및 有限要素法的 硏究
金顯順(Hyun-Soon Kim),南東錫(Dong-Seok Nahm) 대한치과교정학회 1987 대한치과교정학회지 Vol.17 No.2
This paper was undertaken to observe the displacement of craniofacial complex with cervical headgear and to compare narrowing or widening effect of palate by use of contraction or expansion face-bow, respectively. The 3-dimensional finite element method(FEM) was used for a mathematical model composed of 597 nodes and 790 elements and an electrical resistance strain gauge investigation was performed to validate the finite element model. The outer bow of cervical headgear was adjusted to be placed below the occlusal plane by 25° and met the midsagittal plane by 40°, and was loaded 1kg on each right and left hook toward posterior direction. The results were as follows 1. Generally, the maxillary teeth and facial bone were displaced in posterior, medial and downward direction. 2. It was the maxillary 2nd bicuspid that moved bodily. 3. The craniofacial complex rotated in a clockwise direction around the rotating axis which lay from the most posterior and lowest point connecting nasal crest of maxillary bone and vomer, progressively toward a more posterior, lateral and upward direction, anterior and upper area of pterygomaxillary fissure, base of medial pterygoid plate and laterally to the contact area of zygomatic arch with squamous part of temporal bone. 4. No contraction effect was observed by contraction face-bow when compared to the standard face-bow. 5. In case of expansion face-bow, the areas of maxillary 2nd bicuspid, molars and palate were expanded remarkably.

본 연구는 양하의 항산화성 활성과 양하를 첨가하여 4℃에서 21일 동안 저장하면서 품질특성을 분석하고자 하였다. 양하를 첨가한 농도는 5%, 10%, 및 15%를 김치를 제조할 때 첨가하였다. 양하를 첨가한 김치의 품질특성을 보고자 pH, 염도, 무기질 농도, 유산균 함량, 색도변화 및 관능검사를 실시하였다. 총 페놀함량은 양하 1g에는 3.85 μM quercetin 당량, 총 플라보노이드 함량은 양하 1 g에는 0.49 μM quercetin 당량으로 관찰되었다. 양하를 첨가한 김치의 유산균수는 양하 첨가량이 증가함에 따라 증가하는 것을 볼 수 있었으며 특히 10% 첨가한 김치에서 가장 높은 유산균 수를 관찰하였다. 명도의 값은 양하를 첨가할수록 밝기가 밝아지면서 수치가 증가하는 것을 볼 수 있었다. Redness는 양하 첨가구에서 감소하는 경향을 보이면서 10%와 15% 첨가구에서는 양하 첨가에 의하여 붉은 색은 감소하는 것을 보였다. 관능검사에서는 전반적 기호도, 맛, 풍미 및 색의 기호성은 10% 첨가군에서 유의하게 좋게 나타났다(p<0.05). 본 연구결과 양하는 천연항산화제로서 양하를 첨가함으로써 소비자의 선호도를 증가시키는 소재로서 활용가치가 있다. This study investigated the antioxidant properties of yangha(Zingiber mioga Rosc) and quality characteristics of kimchi with added yangha during a 21-day fermentation process at 4℃. Yangha was added to salted cabbage at concentrations of 0, 5, 10, and 15% (w/w). The quality characteristics of kimchi with added yangha were determined by measuring pH, salinity, mineral contents, lactic acid bacteria amounts, color value and sensory evaluation. From the results, total phenolic (3.85 μM quercetin equivalent/g) and total flavonoids (0.49 μM quercetin equivalent/g) contents were measured in yangha. The number of lactic acid bacteria of kimchi with added yangha significantly increased with increasing yangha content, especially 10%. The brightness value increased with increasing yangha content. However, the redness tended to decrease by the addition of 10% and 15% yangha. The consumer acceptability score for the kimchi with added 10% yangha ranked significantly higher than that of the other groups in overall acceptability, taste, flavor, and color(p<0.05). From these results, we suggest that yangha may be used as a natural antioxidant and that it is a good food ingredient for increasing the functionality and consumer acceptability of kimchi.
