e-Learning에서 교수-학습자들 간에 형성되는 지식들을 체계적으로 관리하여 효과적인 교수-학습을 수행할 목적으로 교수자들이 교수 설계 이론에 따른 다양한 강의들에 교육 컨텐츠를 보다 쉽게 저작할 수 있는 시스템을 개발하였다. SCORM 표준에 따라 학습객체 간 관계를 설정하여 저작된 컨텐츠는 학습자가 학습내용을 개념화하는데 도움을 줄 것이다. 시맨틱 웹의 RDF를 적용하여 학습객체 간의 관계를 설정함으로써 지식맵을 구성하였고, 교수자가 해당 분야에서 사용되는 단어를 등록하여 일종의 어휘사전을 만들 수 있는 온톨로지를 도입하였다. 학습자의 이해도와 성취도를 고려한 개별학습을 제공하기 위하여 도입된 상호작용점을 따라 학습자마다 개별적인 학습맵이 구성되어 학생 개인의 학습활동과 이해도를 평가할 수 있다. For the purpose of an effective instruction-learning process by systematic management of knowledge between instructor and learner in e-Learning, we have developed the authoring system in which the instructor is able to author easily on various lecture frames according to the instructional design theory. The authored contents with the relations among the learning objects based on SCORM standard would help learner to conceptualize the contents. A knowledge map is constructed on the relations among the learning objects using RDF of the semantic web. We introduce the ontology in which the instructor can make a dictionary of terminology by registering the words of the teaching area. The learning activity and comprehension of students can be assessed using each student's learning map along the interaction points which are introduced to present the individual learning by considering each student's capacity of understanding and achievement.

The purpose of this research is to assess and understand the health conditions and lifestyle patterns of babies and toddlers who attend preschool and childcare centers in small and mid-sized cities, and provide structure and criteria for implementing the fundamental elements for early childhood education and development. A sample population focused on those attending preschools and child care centers in the Gimcheon area were assessed on June 20 through July 5, 2011 by means of questionaires. These children's health results were found to be higher than the national standard for normal 3, 4 and 5 year old children's health development. Findings also showed there was no difference in the level of partic-ipation in health fitness programs among mothers who held different vocations. This research showed that more children were going to childcare centers per year, which came out to be about 12.77 times more than preschool, which had a slightly lower number of 11.81 times. A slighter higher number of the children attending preschool had mothers who were stay-at-home moms (precisely 12.23 times more) as opposed to those whose mothers worked (11.19 times). Lastly, results showed that the children of mothers who did not work had a higher percentage of eating breakfast rather than those children whose mothers worked.

Henoch-SchonIein purpura is a common form of vasculitis primarily involving the skin, the gastrointestinal tract, the joints, the kidneys, and the nervous system. The etiological investigations are essential, because triggering factors are found in approximately half the patients such as viral, bacterial and parasitic infections, drugs, toxins, systemic diseases and cancer. But it's the correlation between Henoch-SchonIein purpura and Entamoeba histolytica has been rarely reported. We report a 29-years-old woman with Henoch-SchoIein purpura complicated by the lower gastrointestinal bleeding caused by the amoebic colitis. She complained of cramping abdominal pain, lower extremity purpura and hematochezia. Cysts and trophozoites of Entamoeba histolytica were detected in her stool. Skin biopsy demonstrated the leukocytoclastic vasculitis. She was administered metronidazole 1,500㎎ a day for the treatment of amebic colitis. Her hematochezia was improved, but the abdominal pain and purpura were not. The subsequent corticosteroid therapy improved her symptoms.

We propose a fingerprint matching algorithm that compares distance and included angle sequence among minutiaes with another's. We defined this sequence as minutiae constellation which has a basic unit is distance and included angle sequence among three minutiaes. This algorithm searches nearest minutiae from a minutiae and repeatedly searches nearest minutiae from just before searched minutiae. It doesn't search core and is independent of translation and rotation because matching stage only uses distance and included angle sequence.

The purpose of this study were to investigate the effects of participation of health program on health related physical fitness and blood lipids in olderwomen. The subjects participated in this study were 52 older who were participated physical activity program in Korean National University of Physical Education. The analysis of this study utilized one way ANOVA design. The results of the study were as follows : 1. According to taking the treatment periods(0, 6, 12), body composition, hand grip, sit and reach, sit up, and 3200m walking were no significant difference. 3. According to taking the treatment periods(0, 6, 12), TC, TG, LDL-C, HDL-C and VLDL-C were a significant difference in p<.001 levels.
골격근 근형질세망의 ATPase활성도에 대한 Vanillylnonanamide의 영향

To investigate the effect of vanillylnonanamide(VN) on the ATPase activity of the sarcoplasmic reticulum(SR) of the skeletal muscle, we prepared the SR vesicles from the back muscle of the rabbit, and measured ATPase activity. The results as follows: Ca-ATPase activity was about 50% in the total ATPase activity of skeletal muscular SR. In the reaction mixture with calcium, 100μM VN increased ATPase activity to 20%, and 100 nM and 10 μM thapsigargin(THP) inhibited the ATPase activity to 50% and 60%, respectively. And 100 μM VN plus 100 nM or 10 μM THP more inhibited ATPase activity than THP alone did it. However, without calcium, 100μM VN did not affect ATPase activity, and 10 μM THP inhibited it to 41%, but VN plus THP inhibited it to 31%. The above results show that VN in the reaction mixture with or without calcium has the different action to ATPase activity when it is used alone or together with Ca-ATPase inhibitor THP. This suggests that VN might increase or decrease the skeletal SR Ca-ATPase activity through affecting the lipid membrane around the Ca-ATPase.

Every interventional procedure can result in infectious complication even though its incidence is very low. Increases in both indication of procedures and number of immunocompromised patients are likely to result in increase of infectious complications. However, no randomized controlled trials to evaluate the effectiveness of prophylactic antibiotics in interventional procedures have ever been performed. This study was performed to investigate the actual pattern of practice and awareness of medical providers concerning the antibiotic prophylaxis following vascular and nonvascular interventional procedures. A questionnaire regarding prophylactic antibiotic usage was sent to the interventional radiologists in 40 hospitals. A total of 12.2-30.3% responders used prophylactic antibiotics for vascular procedure. More than 80-90% of responders answered that vascular procedures except catheter insertion, are not clear indications of prophylactic antibiotics, In contrast, 31.3% and 51.5% of responders used prophylactic antibiotics for genitourinary and biliary drainage respectively. About 60-70% of responders considered both genitourinary and biliary drainage as clear indications of antibiotic prophylaxis. Further study assessing the appropriate antibiotic usage in interventional procedures is warranted.
