This study was to determine the fiber-type populations and calculate the cross-sectional areas in each fiber-type in the muscle of the brachium of the rat. For 20 rats, the flexors (brachialis and biceps brachii) and extensors (triceps brachii) of the elbow taken from dissection. The fibers were classfied histochemically as fast-twitch oxidative glycolytic fiber(FOG), fast-twitch glycolytic fiber (FG), or slow-twitch oxidative fiber(SO), and their populations were determined. The cross-sectional areas of each type muscle fibers were calculated with microcomputer image analyzer. The results were as follows ; I. The variations in fiber-type population of various muscles with which their positions were observed as well as those reported in ot4er studies. 2. In both extensor and flexor groups, the deep region of the muscles was consisted of higher populaions of SO fibers, while more superficial regions of the same muscles were more FG fibers. 3. The percentage of SO fibers were larger in the extensors than that of flexors. 4. Except the SO fibers, the cross-sectional areas of FOG and FG fibers in the extensors were larger than that of flexors.

Endometriosis is characterized by ectopic growth of tissue resembling endometriosis in various extrauterine locations. So we surgically implanted endometrial tissue to serosal wall of small intestine in rats. After that we administrated Naemak-1-ho-hwan for 10, 20, 40, 60, 80, 100 days. The results were as follows: 1. After 4weeks we could observe tissue resembling endometrium in serosal wall of small intestine. Endometrial tissue which was located serosal wall of intestine had the function of growing, secreting and bleeding. 2. The size of the endometrial tissue in the Naemak-1-ho-hwan administrated group was significantly reduced when we compared with water administrated group (control group) . Further more, as the time goes on, the effect of Naemak-1-ho-hwan much better. 3. In case of infected group, we could find abscess and fibriotic change, also like that case Naemak-1-ho-hwan was not effect. 4. There was no difference between Naemak-1-ho-hwan administrated group and control group in the shape of primordial follicle, primary follicle, maturing primary follicle and ovary size. So these results suggest that Naemak-1-ho-hwan will be effect for the patient who suffer from slight endometriosis.

정보와 통신공학의 발달에 따른 지식 정보화 사회에서 과학교육 특히 교수·학습과정이 중심이 되는 교실 수업은 정보통신공학(ICT)을 활용함으로써 변화되고 있다. 그러나 정보통신 그 자체가 지식 정보화 사회의 과학교육을 보장하는 것은 아니다. ICT와 교육환경과의 상호작용, 교사 역할의 변화, 지식 정보화 사회에 필요한 교수내용과 학습 방법을 위한 교수전략 변화 등이 있어야 한다. 그 방향과 내용에 대한 구체적인 제시가 따라야 한다. 이에 본 연구는 지식 정보화 사회에서 과학교육과 정보공학과는 어떤 관계에 있으며, 지식 기반사회의 중심에 있는 정보통신공학들을 과학 탐구실험에서 적절하게 활용하기 위한 예를 제시함으로써 과학 탐구실험의 방향을 탐색해 보고자 하였다. The development of information and communications technologies (ICT) is changing school education, which is a center of teaching/lession process. Information and communication technologies can not guarantee quality education appropriate for knowledge & information society. Interaction between ICT and educational environment, change in the role of teachers, and shift in teaching strategies for educational contents and learning method would be required. This paper has studied the relationship between science education and ICT, change on the role of teachers, and a direction in teaching strategies to take advantage of ICT in science education.

The purpose of this study is to increase the teachers' awareness of safety and help increase the children’s ability for safety by researching and analyzing the types of accidents, the current condition of safety education and the environment in which children play. Also this research suggests methods of effective safety education that would teach the children a proper perception and attitude towards safety. For the research, this study implemented frequency analysis and cross-tab analysis by using survey data. According to this research, the current safety education programs majorly focus on, in order of importance, the safety of the children’s playtimes(51%) and fire safety education(45%). The largest number of teachers responded that they most frequently use conversation(62%) as the method of safety education. In addition, the majority of teachers(73%) have not received any training for conducting safety education. This research indicated a necessity for an effective safety education program and a concrete teacher training that could enhance the children’s safety abilities. Finally this study suggested the current limitations of the nursery schools' safety education and the methods to improve such programs.

Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.
