Based on an analysis on the difference on the measurement sites and their relations to osteoporosis diagnosis and prevalence, this study attempts to investigate the patterns of prevalence in skeletal sites in the aging process. The samples were driven by the National Health and Nutrition Examination Survey (2008-2010) on Korean females (n = 4,449) aged from 50 to 89 years. The result shows that the differences on affected sites in the aging process were detected as follow: the osteoporosis prevalence in lumbar spine was relatively high in 50s, 60s and 70s; however, the prevalence in the proximal femur (total hip and femoral neck) was higher in 80s. In terms of the diagnosis identified in a single site, the prevalence in lumbar spine seemed to decrease as age increases; but, the rate went up in the figure of femoral neck. Overall, the osteoporosis prevalence for the diagnosis detected in multiple sites was increased as age goes up. In general, the increase in lumbar osteoporosis prevalence starts earlier than that of femoral neck. The findings of this study also suggests that if the proximal femur site is only used for diagnosing women age in 50s, 60s and 70s, the significant portion of osteoporosis patients could be misdiagnosed as normal.

Treatment of esophageal perforation when diagnosed late remains controversial. Ten consecutive patients since 1990 were treated late(later than 24 hours) for esophageal perforation with primary repair. Four perforations were iatrogenic, 3 were spontaneous, 2 were foreign body aspiraton and 1 was trauma. The interval from perforation to operation was 116 hours in mean and 48 hours in median value. The principles of repair included (1) a local esophagomyotomy proximal and distal to the tear to expose the mucosal defect and intact mucosa beyond, (2) debridement of the mucosal defect and closure, (3) reapproximation of the muscle, and (4) adequate drainage. The repair was buttressed with parietal pleura or pericardial fat in 9 patients. Associated distal obstruction was treated with dilation and esophagomyotomy intraoperatively. There was one mortality and cause of death was massive gastric bleeding due to gastric ulcer on 33rd day after operation. Five patients had leak at the site of repair and these cases were treated completely with conservative treatment except a mortality case. In conclusion, in the absence of malignant or irreversible distal obstruction, meticulous repair of perforated esophagus and adequate drainage are preferred approach, regardless of the duration from the injury to the operation.

Apparent washout of T1-201 may occur between redistribution and reinjection images. To examine the frequency of it, we prospectively compared 4-hour redistribution and reinjection images in 63 consequent patients. All patients underwent pharmacological stress test using 0.56 mg/kg dipyridamole. Immediately after the 4-hour redistribution images, 1 mCi T1-201 was injected at rest, and images were reacquired 10 minutes after reinjection. The stress, redistribution, and reinjection images were then analyzed semiquantitatively (0=no uptake, 1=faint uptake, 2=mildly diminished uptake, 3=normal uptake). Of the 100 abnormal myocardial regions on the stress images, 54 showed either complete or partial reversibility on 4-hour redistribution images. After reinjection 11(21.2%) of these regions demonstrated apparent T1-201 washout due to low differential uptake of the tracer. Such lesions would appear irreversible if redistribution imaging is not performed before reinjection. Thus 4-hour redistribution imaging should be performed for assessment of myocardial ischemia and viability.

The study was carried out to investigate the variations in the fibroin hydrolysis of different cocoon shell layers, and the relationship between the hydrolysis and silk physical property. The obtained results are as follows: 1. The fibroin hydrolyzing ratio was highest at the inner layer of cocoon shell and. next in order. at the middle layer and at the outer layer. 2. The fibroin hydrolyzing ratio of abnormal cocoons was higher than normal cocoon and it was different among them, tile highest was double coroon, thin shell cocoon and perforated cocoon in order. 3. The sericin content and fibroin hydrolyzing ratio of Jam 111 and Jam 112 was higher than that of Jam 111 $\times$ Jam 112. 4. The fibroin hydroiyzing ratio of the cocoons fed with the artificial diets was increased at the inner layer. The sericin content of those lessened at the inner layer, however, it slightly increased at the most inner layer more than at the inner layer. 5. The breaking strength of the degummed silk fiber of different cocoon layers was reduced at the inner layer. The breaking Strength of abnormal silk fiber was less than that of normal silk fiber. 6. A negative correlation (r= －0.8) )was approved between fibroin hydrolyzing ratio and breaking strength of silk fiber, and the regression line was Y=－0.29x＋5.07.

This study was carried out in order to investigate the functional properties of 50% methanol extracts from four parts (root, stem, leaf and fruit) of Acanthopanax sessiliflorus by means of measuring the contents of eleutheroside B, E, and total polyphenols as well as determining electron donating ability (EDA), nitrite scavenging ability (NSA), and anticancer activity. The highest contents of eleutheroside B and E were found in the fruit (538.99 ${\mu}g/g$) and the stem (556.00 ${\mu}g/g$). The root extract demonstrated the highest polyphenol content (2.97 mg/g). EDA of the stem and root extracts were 90.21% and 85.71%. All of the extracts showed 81.5-93.0% of NSA at pH 1.2. In addition all extracts indicated no cytotoxicity to normal cell line (DC2.4). The root extract had a 23% inhibitory effect against the stomach cancer cell line (SNU-719). These results revealed that 50% methanol extracts from A. sessiliflorus can be used as a potential resource of nutraceuticals.

In this study, water content, sebum content, and transepidermal water content were investigated to provide basic data for the future cosmetics industry as comparing the skin characteristics of different ages. Water content of cheek area, sebum content of nose area, and transepidermal water loss (TEWL) of cheek and forearm of trial subjects (total 638 people of both male and female) were measured. Data were analyzed using Statistical Package for the Social Sciences program (version 19.00; SPSS Inc., Chicago, IL, USA). Water content, sebum content, and TEWL of skin were measured as mean ${\pm}$ standard deviation. As a result, water content of cheek from female was higher than male and the water content increased with the older ages. However, sebum content of nose from male was higher than female and the sebum content increased with the younger ages. TEWL of cheek from female was higher than male, but TEWL of forearm from male was higher than female. Therefore, these results can be used as basic data in the development of future cosmetics for different ages and genders.

A 10-month-old intact male Labrador Retriever dog was referred with the primary complaint of exercise intolerance, especially after vigorous exercise. Physical examination revealed split S1 and grade III/VI diastolic regurgitant murmur at the left apex and base, respectively. ECG finding was normal sinus rhythm at rest, but supraventricular tachycardia with bundle branch blocks after exercise. Thoracic radiography revealed dilated ascending aorta with normal range of cardiac silhouette (VHS 10.2). Echocardiography revealed abnormal valvular structures just above the aortic valvular cusps causing aortic regurgitation with a reduction of left ventricular ejection fraction (LVEF). Based on those findings, the case was diagnosed as congenital aortic regurgitation caused by abnormal valvular structures. The dog was managed with diltiazem and exercise restriction. This is a rare case of aortic deformity in dogs.

비유선형의 물체 주위의 유동은 정체유동, 경계층 박리 및 주기적 와열 생성 등의 복잡한 유동현상이 공존한다. 본 연구에서는 비교적 단순한 형상인 정사각주 주위의 비정상 난류 유동을 2-방정식 와점성 난류모델인 표준 $k-{\varepsilon}$ 모델과 RNG $k-{\varepsilon}$ 모델을 이용하여 예측할 수 있는지를 검증하였다. 정교하게 수행된 최근의 실험과 대와류모사(LES)의 결과를 검증을 위한 비교의 자료로 삼았다. 적절한 난류모델의 선정과 더불어 시간 정확도, 공간 정확도 및 대류항 처리법 등이 해석결과에 미치는 영향도 살펴보았다. 기존의 표준 $k-{\varepsilon}$모델은 정체점 부근에서 난류 운동에너지를 과도하게 생성하는 근본적인 문제점 때문에 실험 및 LES의 결과를 제대로 예측할 수 없었다. 난류운동에너지의 초과 예측에 따른 운동량의 과도한 혼합으로 인해, 항력계수 및 양력계수의 비정상성 뿐 아니라 평균 항력계수도 부정확하게 예측하였다. RNG $k-{\varepsilon}$ 모델을 사용한 경우에는 정체점 주위 유동현상의 예측이 상당히 향상되어 항력계수 및 양력계수의 평균치, 진폭 및 비정상성의 주기 등을 정확하게 예측하는 것이 가능하였다. 그러나 이 경우에도 예측의 정확도가 시간 증분과 격자의 크기 및 대류항 처리법등에 영향을 받으며, 특별히 대류항 처리법에 상당히 민감하게 변하는 것을 알 수 있었다. 향상된 유동예측은 RNG $k-{\varepsilon}$ 모델의 난류에너지 소산율 방정식의 개선된 항이 과도하게 생성된 난류에너지를 정체점 부근에서 제거하기 때문에 가능하다는 것을 알 수 있었다.의 20세 이하 골절 및 탈구가$30.3\%까지 감소하게되어 년도가 증가함에 따라 청장년 층에 비하여 소아골절 및 탈구가 전체적으로 감소하는 경향을 보였다. 스키골절의 부위별 발생빈도는 1990년 이전까지 하지골절 및 탈구가 많았으나 이후 점차 상지의 골절 탈구가 증가하였다 하지에서 가장 많은 골절은 경골 골절이었으며, 경골골절은 회전력에 의한 나선형골절이 $76.5\%로 가장 많았고 년도에 따른 변화는 보이지 않았다. 스키손상의 발생빈도는 초기에 비하여 점차 감소하는 경향을 보였으며, 손상의 특성도 부위별, 연령별로 다양한 변화를 나타내었다.해가능성을 가진 균이 상당수 검출되므로 원료의 수송, 김치의 제조 및 유통과정에서 병원균에 대한 오염방지에 유의하여야 할 것이다. 확인할 수 있었다. 이상의 결과에 의하면 고농도의 유기물이 함유된 음식물쓰레기는 Hybrid Anaerobic Reactor (HAR)를 이용하여 HRT 30일 정도에서 충분히 직접 혐기성처리가 가능하며, 이때 발생된 $CH_{4}$를 회수하여 이용하면 대체에너지원으로 활용 가치가 높은 것으로 판단된다./207), $99.2\%$(238/240), $98.5\%$(133/135) 및 $100\%$ (313)였다. 각각 두 개의 요골동맥과 우내흉동맥에서 부분협착이나 경쟁혈류가 관찰되었다. 결론: 동맥 도관만을 이용한 Off pump CABG를 시행하여 감염의 위험성을 증가시키지 않으면서 영구적인 신경학적 합병증을 일으키지 않았고 좋은 혈관 개존율을 보여주었다. 따라서 동맥 도관을 이용한 Off pump CABG는 관상동맥의 협착의 정도에 따라 효율적으로 시행

'Yumyeong' peach has desirable characteristics of long shelf-life and specific non-melting nature with long harvesting period. However, some fruits harvested too late tend to show fruit pithiness symptom or internal breakdown. The study was conducted to investigate the differences between fruit flesh pithiness and internal breakdown symptoms, and to find out inducing factors of flesh pithiness in 'Yumyeong' peach. The incidence of flesh pithiness was higher in the fruits harvested late. Sugar and malic acid contents were not different between normal fruits and flesh pithiness fruits, but the acidity was significantly lower affected by low citric acid content in flesh pithiness fruit. In flesh pithiness fruits, calcium contents were low in both skin and flesh. Occurrence of flesh pithiness fruits was high in the years with low precipitation and high temperature for 2 months before harvest. In observations on morphological characteristics, the parts showing flesh pithiness consisted of smaller cells than the normal parts. Tonoplasts were disintegrated and the number of dead cells was high in internal breakdown fruits, while the tonoplasts were intact with contracted vacuoles in flesh pithiness fruits. Tylosises were observed in vascular tissues around the flesh pithiness, therefore, it was assumed that those tylosises restricts flesh tissue development resulting in flesh pithiness. Other varieties such as 'Fantasia' and 'Wolmi' also showed tylosis and smaller cells were observed in the flesh tissue of these cultivars, indicating abnormal growth of the flesh part. These results suggested the possibility of the occurrence of pithiness like symptoms in other peach varieties.
