The purpose of this study was to examine the children's computer activity concerning their working mother's recognition, home environment and current operation at their home. 109 working mothers who sampled in 5 day care centers were selected as the subjects of this study. This study was performed by the questionnaire made by this researcher, and the data were analyzed with Frequency, Percentage. The results of this study are as follows, Working mother's recognition on the need of young children's computer activity was positive(91.8%0. Working mother thought that young children's computer activity was needed for young children's various experiences(24.7%) and the preparation for the future life(22.6%). The most important objective of young children's computer activity was to help children get familiar with the computer(30.3%). And working mothers recognized that the effect of young children's computer activity was to promote their children's originality, imagination and insight. The environment of young children's computer activity in the working mother's home was sufficient(75.3%). Most have their own computer hardware and peripheral equipment. And the computer's installation environment was set up well. Young children did computer activities with parents(33.3%) or brothers(47.4%) at their livingroom. It took one hour for young children to do the computer activity at home(75.7%). The degree of possession of the software in working mother's home was 1-5(50.0%). Working mother put a software at young children's computer activity from the beginning(65.4%). And they confirmed the contents of the software. A standard of buying the software was mainly inducement that people had ever that software(24.1%). Working mother recognized on the possessing software that were appropriate for their children's age and educational. An obstacle about children's computer activities in their home was shown to be insufficient of possessing appropriate software for the child. For the activation of the children's computer activity, it was required to possess various and appropriate softwares. For children's computer activity was connected with day care center's, working mother wanted to take part in parent's seminar(36.6%) or participation class for parents(23.4%).

The purpose of this study is to understand general safety of school buses and safety education at early childhood education center, analyze teachers' awareness and needs for safety of a school bus, and present fundamental data for teachers to protect young children against possible incidents at a early childhood education center. To grasp the conditions of safety of a school bus, safety education, and teacher's awareness and needs for the bus, a survey was conducted with 171 teaches who got on a school bus to bring in and out young children at kindergartens and child care center in Seoul area. The results of this study were as follows: First, as for safety of a school bus at early childhood education centers, young children used a school bus to attend a center and many buses had 15 to 25 seats at most early childhood education centers (70.3%). In terms of school buses, they were good at being insured, yellow vehicles, emergency network, and teachers' boarding but were poor at children protection mark attachment, observance of the seating capacity, and wearing a safety belt. Only about a half (54.4%) were registered as children protection vehicles; thus, young children could hardly be protected by the children protection vehicles. After investigating home-coming guidance for young children using a school bus at an educational center, teachers led young children to parents in most cases, while parents came out to send and meet them in a half of the cases; therefore, parents are required to change their perception of young children's safety. It was found to take about one hour a day on average for teachers to get on a school bus to young children. Second, in terms of safety training for a school bus at early childhood education centers, most centers (60.8%) provided parents about once or twice a year with information on the use of school buses in the form of newsletter. While young children's safety training for a school bus provided during regular classes and in need of safety guide for attending the center, there were difficulties due to the lack of educational materials related to safety training for a school bus and the want of concerns by the centers. Third, as for teachers' awareness and needs for safety of a school bus, teachers thought of a school bus as the center as relatively safe; however, nearly a half of the teachers failed to know the provision of children protection vehicles and penalties.

수학자 이상설이 소개한 근대자연과학: <식물학(植物學)>

박영민 ( Young Min Park ),김채식 ( Chae Sik Kim ),이상구 ( Sang Gu Lee ),이재화 ( Jae Hwa Lee ) 한국수학교육학회 2011 수학교육논문집 Vol.25 No.2

본 원고는 2004년 과학사학자 박성래 교수가 독립 운동가이자 한국 근대 수학교육의 아버지로 부르기 시작한 보재 이상설(李相卨, 1870-1917)이 자연과학에 기여한 내용을 다루고 있다. 한국수학사학회지 2009년 11월 호에 자세히 소개된 〈數理〉를 쓴 시기를 전후하여, 같은 시기에 이상설이 붓으로 쓴 것으로 여겨지는 〈植物學>(이상설, 1899)은 총 4면의 초록 필사본이며, 그 대본(臺本)은 〈植物學啓蒙〉 (Edkins, 1886)으로 영국의 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 〈西學啓蒙〉 16종 가운데 하나이다. 이상설의 〈植物學>은 이 〈植物學啓蒙〉을 읽으면서 그 책의 내용 중 당시의 조 선 학자가 모르고 있던 새로운 내용을 중심으로 메모를 한 것으로 여겨진다. 본 연구에서는 전통산학과 근대서양수학을 연결하는 〈數理〉를 저술했으며. 우리나라의 정규 교과과정에 수학과 과학을 필수과목으로 지정하고, 첫 번째 수학교과서 〈산術新書〉를 발간함으로 당대 최고의 수학자로 평가된 이상설이 쓴 〈植物學〉을 발굴하여 그 내용과 의미를 최초로 분석한다, 이를 통하여 당시 조선의 서양 과학, 특히 식물학에 대한 이해 수준을 분석하고 〈植物學〉의 원전인 〈植物學啓蒙〉 과 <西學啓蒙〉의 저자에 대하여 알아본다. 이는 당시 수학교육자가 자연과학분야에 행한 교육적 기여를 이해 하는데 필수적인 연구이다. This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee`s book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people`s level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers for Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

Strongyloidiasis is a parasitic disease caused by Strongyloides stercoralis which exists in two forms : the free living and parasitic forms. It exists in warm, moist climate in areas where there is frequent fecal contamination of the soil. After cutaneous invasion by the filariform larvae, petechial hemorrage, pruritus, papular rashes, edema, and urticaria occur. Infection commonly occurs in the proximal intestine of the gastrointestinal (G-I) tract but may extend from the stomach to the anus. Once the worm is established in the small intestine, the physical findings may include epigastric tenderness to palpation. The mucosal biopsy is an inefficient way of making the diagnosis because the worm is found in the biopsy specimen in only 2% of patients. Gastric strongyloidiasis is rare. We experienced a case of gastric strongyloidiasis diagnosed by the endoscopic biopsy and serologic test for parasite specific IgG antibody by micro-ELISA.

Malignant hyperthermia is the disorder of calcium regulation within skeletal muscle associated predominantly with anesthesia. It is triggered by volatile anesthetics and depolarizing neuromuscular blocking agents. We experienced a case of malignant hyperthermia. 50 years old female patient was transferred to our emergency room that she was developed tachyarrhythmia and high fever. She was taken arthroscopic examination under the general anesthesia with enflurane and succinylcholine. We suspected malignant hyperthermia and promptly treated her with dantrolene sodium. She was developed disseminated intravascular coagulopathy and acute renal failure then we were intensive care to her. She was discharged without sequela. We experienced successful management of malignant hyperthermia.

The aerozolization is one of possible Brucella transmission mechanisms, particularly in air-borne exposed laboratory workers. In this study, seven laboratory workers were potentially exposed to B. abortus via aerosols. Two laboratory workers who sniffed an agar plate several times were considered to be at high risk for acquiring the disease, 5 workers who did not work directly with the strain were be considered at low risk of infection. Prophylactic antibiotics of doxycycline 200 mg/day and rifampin 600 mg/day were offered for 6 weeks in high risk workers and 3 weeks for low risk workers respectively. Enrolled workers were advised to check for serological testing of Brucella species every 3 weeks during a total period of 12 weeks. Compliance with taking medicine was 57.1% (4/7) and compliance for completing the serological tests was 85.7% (6/7). None of the laboratory workers developed clinical disease or tested positive serologically during 3 months of seroloaical testing and 1 year of clinical follow-up.
