As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

Purpose: This study was done to explore time management behavior and self-efficacy in nursing students and to analyze the correlations between time management behavior and self-efficacy. Methods: The data were collected from May 12 to 20 2010 using self-report questionnaires about time management behavior and self-efficacy of nursing students. The data from 508 students were analyzed using descriptive analysis, K-means clustering, and one-way ANOVA. Results: The mean score for time management behavior was 3.03±1.11 out of a possible 5, and self-efficacy was 3.65±0.42 out of a possible 6. Four groups were identified according to time management behavior. The four groups were significantly different on self-efficacy total (p=<.05) and self-regulatory efficacy (p=.<005). The group with the highest score for time management had the highest score for self-efficacy. Conclusions: The results of the study indicate that time management behavior styles are related to self-efficacy for nursing students. Therefore, time management education programs based on the time management behavior styles are needed to increase self-efficacy in nursing students.

소아에서의 Garre 골수염

우세은,김영진,김현정,남순현 大韓小兒齒科學會 2011 大韓小兒齒科學會誌 Vol.38 No.4

Garre’s osteomyelitis is associated with bacterial infection and bone necrosis resulting from obstruction of blood supply. The most common cause for Garre’s osteomyelitis is odontogenic infection that originates from periodontal tissue or dental pulp. Subperiosteal abscess may also cause Garre’s osteomyelitis in the progress of the infection. Mandible is more often affected than maxilla, most commonly in the permanent first molar region of mandible. Clinically, it results in a hard swelling over the jaw, producing facial asymmetry. Meanwhile, radiograph shows a characteristic feature of irregular pulpal cavity, showing new periosteal proliferation located in successive layers to the condensed cortical bone on stimulated site. The treatment method for Garre’s osteomyelitis are removal of the infection source, root canal treatment, antibiotic medication, and incision and drainage. This report presents a case of Garre’s osteomyelitis under 15 years old. The patient was successfully treated by antibiotic medication accompanied with root canal treatment. Since the symptom of pediatric patients is less severe than adult, careful diagnosis with history taking and clinical examination is necessary. Furthermore long-term follow-up examination is needed to prevent recurrence even after the symptom disapears. Garre 골수염은 혈류 순환 및 영양 공급의 장애로 골이 괴사되거나, 세균 감염이 증가되면 발생한다. Garre 골수염은 치수 나 치주 감염에서 시작된 치성계 감염과 이의 진행에 따른 골막 하 농양이 주요 원인이 되며, 외상으로 인한 악골의 복합 골절 시 2차 감염, 국소적인 치은의 외상에 의해서도 발생할 수 있다. 상악에서보다 하악에서 많이 발생되며 호발 부위는 하악 제 1대구치이다. 임상증상으로 이환 부위의 하악골은 팽창되어 있으나 구강점막은 정상적 색조를 가지며 안면 불균형을 나타낸다. 방사선 사진 상 심한 우식증을 가진 치아의 치근단 병소를 관찰할 수 있으며, 자극을 받는 골조직 부위의 치밀골 증가로 골수강은 좁 아지거나 폐쇄되며 외양이 불규칙하게 나타난다. 치료 방법으로는 항생제의 투여, 원인치의 발치 또는 근관치료, 절개 및 배농술 등이 알려져 있다. 본 증례는 15세 이하의 소아환자에서 악골 골수염이 발생한 경우, 장기적인 항생제 투여나 항생제 투여 및 근관 치료를 병 용하여 성공적으로 치료된 증례이다. 소아 환자의 경우 성인에 비하여 증상이 경미하므로 주의 깊은 병력 청취와 임상 검사를 통한 진단이 요구되며, 증상이 사라진 경우에도 재발을 방지하기 위하여 장기간의 추적 검사가 요구된다.

This paper presents design and implementation of an information retrieval system for a large volue of an image database. Our system supports three kinds of queries: attribute-based queries, keyword-based queries, and color-based queries. The attribute-based query is the most-typical query that finds target images based on their attribute values. The keyword-based query is to find target images by referring to their description information their attribute values. Finally, the color-based query is to search for target images by comparing the colors of a query image with those of images in the database. In this paper, we presents the system architecture and approaches adopted in our system for supporting the above three queries effectively and efficiently. We also discuss the user interface of our system that enables users to manipulate our system easily and conveniently.

A primary central nervous system lymphoma(PCNSL) is defined as a lymphoma limited to the cranial-spinal axis without systemic involvement. PCNSLs were formerly very rare, only 0.5∼ 1.2% of all intracranial neoplasms, and were usually associated with acquired immuno-deficiency syndrome(AIDS) and other immune-compromised states. Recently, there has been a clear rise in the incidence of this disease among normal individuals. We describe a 77-year-old female with hyponatremia who presented with a confused mental state. Computed tomography(CT) of the brain demonstrated a suprasellar mass with enhancement. We evaluated the basic hormonal studies and the magnetic resonance imaging(MRI). A ventricular biopsy was done, and the result was a diffuse, large, B-cell-type malignant lymphoma. She presented panhypopituitarism and partial central diabetes insipidus. She received chemotheraphy and was discharged in an improved condition. We report a case of panhypopituitarism due to PCNSL and give a review of the literature.

Purpose: Given the increased frequency of operative therapy and radiation therapy on breast cancers and uterine cancers, there is very little information on lymphedema associated with these treatments in Korea. Thus, the authors conducted this study to describe and analyze the data which they had obtained from the patients. Method: A retrospective study was undertaken on 840 patients who registered to the Lymphedema Clinic of Samsung Seoul Hospital throughout the period of February 1995 to August 2001. Result: Out of 840 patients, 205 patients (24%) were confirmed as having primary lymphedema, while 635 patients (76%) had secondary lymphedema. The ratio of male to female for primary lymphedema was 1 :1.8(Male : Female), while secondary lymphedema demonstrated to be 1:21 (Male : Female), demonstrating a female preponderance. Secondary lymphedema mostly developed after undergoing treatment for uterine cancer (341 patients, 53.7%) and breast cancer (226 patients, 35.5%) The lesions of occurrence for both primary and secondary lymphedema were mainly in the lower extremities than the upper extremities. In regards to the degree of clinical edema, a large number of the patients, that is 633 patients (76%) had progressed to Stage Ⅱ~Ⅲ. Among the patients who developed edema after undergoing treatment for cancers, only 43 patients (7%) were provided information on the possibility of developing lymphedema, while the majority of the patients had no knowledge about this possibility. When the patients' subjective experiences were investigated on the degree of the edema, there was no significant increase in pain despite an increase in the degree of the edema (P<0.05), nevertheless, a significant increase was found in cosmetic problems (P>0.05). Conclusion: As a general rule, complete recovery from chronic lymphedema is not expected. However, early detection of lymphedema and timely appropriate treatment as well as aggressive patient education on lymphedema and its related complications can prevent its progression.

청채류의 수확후 생장조절제 처리가 신선도 유지(녹색·중량·Vitamin C의 유지)에 미치는 효과

김정길,지금수,은세기 群山敎育大學 1972 論文集 Vol.5 No.-

청채류의 신선도를 관찰하기 위하여 1971년 7월 중순부터 9월중순까지 고온기에 다음과 같은 실험을 하였다. 1. 녹즙용인 Comfrey kale를 수확한 후에 gibberellin과 OMH-30을 예비실험(1차)을 거친 적당한 농도(gibberellin 5ppm ·OMH-30 100ppm)로 하고 5∼7일간 3회 반복으로 침지한 다음 중량 ·녹색 ·Vitamin C의 유지도를 검정하였다. 2. 그 결과는 OMH-30 처리구가 신선도유지(중량 ·녹색 ·Vitamin C유지도 )에 효과가 있고 gibberellin처리구는 물(수도물)처리구인 표준구에 비하여 효과가 적었다. (Fig. 1-6) 3. OMH-30은 사람에게 독성이 없기 때문에 선도유지제로서 적당하다고 생각되며 앞으로 구명할 것은 수확전 처리를 하였을 때 수확후에는 선도유지 효과가 얼마나 되는가에 대해서이며 또한 gibberellin의 효과도 기대할 수 있을런지 흥미롭다. For the effects of plant growth regulators on the maintenance of freshness of vegetables after harvest, we conducted the following experiments during the hot season, from July to September, 1971. While dipping into water, gibberellin and OMH-30(Diethanol amine 58%, Maleic hydrazid 30%) comfrey and kale were observed their variations of greenness, weight and vitamin C contents. The greenness of vegetables was observed visually, while the variation of ascorbic acid contents was determined by indophenel titration method. The results are as follows; 1. After the preliminary experiment, the vegetables were soaked into water and the appropriate concentrations of the chemicals, namely gibberellin-5ppm, OMH-100ppm respectively. 2. The OMH-30 treatment is the most satisfactory in keeping vegetable fresh longer, while the gibberellin treatment is less effective than the water treatment (Fig. 1-6). 3. We conclude that OMH-30 can be used for the preservation of freshness of vegetables, since it does not have any poisonous effects on human body at all.

Purpose: Small calibered prosthetic vascular grafts are prone to low patency rates after bypass surgery due to its high thrombogenicity and neointimal hyperplasia. Endothelial cells are known to inhibit thrombus formations, platelet aggregation and smooth muscle cells proliteration. The purpose of this study was to examine the development of autologous endothelial cell seeded prosthetic vascular graft. Method: The autologous endothelial cells (ECs) were harvested from canine external jugular veins. Approximately 5*10^4 ECs were obtained through passage 5 to 6 under the static condition. The cultured ECs were seeded into the polytetrafluoroethylenc (PTFE) graft and cultured for 3 days before implanting into the canine carotid artery.The PTFE graft was harvested at 6 weeks after implantation. Result: The primary cultured ECs were treated with Factor VⅢ/WF, CD3]/PECAM-1 antibodyand confirmed with fluorescence micrograph, The gratf patency rates were 2/6 (33%) in the control gratf and 5/6 (83%) in the ECs seeded graft at 6 weeks after implantation. the entire luminal surface of the EC seeded graft was covered with ECs. Only the vicinity of the anastomosis site was covered with ECs in the control graft. Conclusion: This is a pilot study for the development of autologous endothelial cell seeded prosthetic vascular graft. The results of our study demonstrate that the endothelialized PTFE are better than ninendothelialized PTFE.

Effects of 27.12 MHz Radio Frequency on the Rapid and Uniform Tempering of Cylindrical Frozen Pork Loin (Longissimus thoracis et lumborum)

Eun Ji Choi,Hae Woong Park,Hui Seon Yang,Jin Se Kim1,Ho Hyun Chun 한국축산식품학회 2017 한국축산식품학회지 Vol.37 No.4

Quality characteristics of frozen cylindrical pork loin were evaluated following different tempering methods: 27.12 MHz curved-electrode radio frequency (RF) at 1000 and 1500 W, and forced-air convection (FC) or water immersion (WI) at 4ºC and 20°C. The developed RF tempering system with the newly designed curved-electrode achieved relatively uniform tempering compared to a parallel-plate RF system. FC tempering at 4°C was the most time-consuming process, whereas 1500 W RF was the shortest. Pork sample drip loss, water holding capacity, color, and microbiological quality declined after WI tempering at 20°C. Conversely, RF tempering yielded minimal sample changes in drip loss, microstructure, color, and total aerobic bacteria counts, along with relatively uniform internal sample temperature distributions compared to those of the other tempering treatments. These results indicate that curved-electrode RF tempering could be used to provide rapid defrosting with minimal quality deterioration of cylindrical frozen meat block products.
