이 연구는 시각장애아동의 운동능력의 실태를 알아보기 위해 단계적으로 접근하고자 하며, 우선 시각적 모방이 가능한 저시아동을 중심으로 운동능력 실태 및 연령별 발달의 경향을 알아보고자 한다. 이에 초등부 저시아동의 운동능력을 조사 분석하여 운동발달의 경향을 알아봄으로써, 시각장애아동의 신체활동과 관련된 교과교육과 개별화교육계획 및 교수-학습과 정의 계획을 수립하는데 기초자료를 제공하고자 한다. 이 연구의 결과 초등부에 재학 중인 저시아동은 저시아동의 성별에 따른 운동능력의 차이는 없었으나 생활연령에 비해 운동연령이 평균 48.31개월 정도의 지체를 보였으며, 생활연령 증가에 따른 운동능력 발달경향은 생활연령이 증가함에 따라 저시아동은 그들의 생활연령에서 기대되는 운동능력보다 현저하게 지체됨을 알 수 있었다. 이 연구의 결과를 토대로 시각 손상 아동의 학령기에서의 두드러진 지체를 보완.완화하기 위해 초등학교 저학년 시기에 적절한 운동발달 프로그램을 적용한다면 이러한 지체의 심화 과정을 좀 더 완화 시킬 수 있을 것이라 생각된다. 또한 저시아동의 지체된 운동능력을 보상하기 위한 적절한 운동발달 프로그램의 개발과 적용이 필요하다고 생각된다. 이러한 프로그램의 적용은 이후 계속되어지는 학령기 동안 저시아동이 적극적으로 신체활동이나 스포츠 또는 여가 활동에 참여할 수 있는 계기를 제공할 수 있을 것이다. The purpose of the study was to investigate low vision children``s tendency toward motor abilities and the development. The participants who have low-visual acuities consisted of 26 male students and 23 female students from 7 elementary special education school across the country. In addition, participants do not have any multiple disabilities except visual impairment. The sample was a purposive sampling method and it was examined and analyzed through Oseretsky test of motor proficiency The major findings of the study are summarized briefly below Fristly, comparing with total motor age and sub-categorical motor age, the results of the study, contact in the proper place for 0.89 months, contact in hand operation for 0.65 months, motor speed for 1.14 months, single operation accomplishment ability for 0.57 months were delayed. But there was a degree of development between contact in general operation for 1.25 months and same time voluntary operation for 1.29 months. There was statistically a significant differences for the results and there was statistically no significant differences for only single operation accomplishment ability Secondly, motor age delay was 48. 31 months average comparatively with chronological age and there was differences at the .001 significance level. Thirdly, There was no significance differences about gross motor abilities between male and female students who have visual impairment. But, there was a significant difference(p >.05) that female students than to the male students was delayed 7.92 months for motor speed among motor abilities in sub-category fourthly, as chronological age increasing, The development and process of the gross motor abilities of children with visual impairment little bit improved. But each age group showed motor delay from 28 months to 62.53 months and the more chronological age, the worse degree of delay The results of the study is able to provide basic information in terms of planning of subject education related motor activities, individualized education plan, and process of instruction and learning

Background: Memory T lymphocytes of the immune system provide long-term protection in response to bacterial or viral infections/immunization. Ag concentration has also been postulated to be important in determining whether T cell differentiation favors effector versus memory cell development. In the present study we hypothesized that naive Ag-specific $CD4^+$ T cells briefly stimulated with different Ag doses at the primary exposure could affect establishment of memory cell pool after secondary immunization. Methods: To assess this hypothesis, the response kinetics of DO11.10 TCR $CD4^+$ T cells primed with different Ag doses in vitro was measured after adoptive transfer to naive BALB/c mice. Results: Maximum expansion was shown in cells primarily stimulated with high doses of ovalbumin peptide $(OVA_{323-339})$, whereas cells in vitro stimulated with low dose were expanded slightly after in vivo secondary exposure. However, the cells primed with low $OVA_{323-339}$ peptide dose showed least contraction and established higher number of memory cells than other treated groups. When the cell division was analyzed after adoptive transfer, the high dose Ag-stimulated donor cells have undergone seven rounds of cell division at 3 days post-adoptive transfer. However, there was very few division in naive and low dose of peptide-treated group. Conclusion: These results suggest that primary stimulation with a low dose of Ag leads to better memory $CD4^+$ T cell generation after secondary immunization. Therefore, these facts imply that optimally primed $CD4^+$ T cells is necessary to support effective memory pool following administration of booster dose in prime-boost vaccination.

Vibro crushed-stone compacted pile (VCCP) method is one of a ground improvement technique by a vibro compaction in vertical direction with crushed stone to build up stone pile foundation in other to ensure stability of soft ground. In spite of its long applied history in geotechnical engineering division, most of studies have not been based on the reliable In-situ condition but on the laboratory tests including model tests. These model tests can express standard and ideal behavior but exceptional status that can be occur in the ground cannot be considered efficiently. This study performed the the series of trial construction to investigate the effect of VCCP method on the improvement of soft ground expecially in railroad construction site.

본 연구에서는 국내 낙동강 수계에서 신규하게 분리된 미세조류인 Parachlorella sp. 종의 바이오매스 및 지방산 생산성에 대한 배지의 영향을 연구하였다. 미세조류 배양에 통상적으로 사용되는 BG-11, TAP, BBM 배지를 사용하여 바이오매스 생산성은 TAP 배지에서, 지방산 축적은 BBM 배지에서 가장 잘 일어나는 것으로 확인되었고, 지방산 생산성을 향상시키기 위해 암모니아와 아세트산을 사용하는 TAP 배지의 조성을 변화하여 BBM 배지처럼 지방산 축적을 유도하며 바이오매스 생산성을 증가시킨 MTAP 배지를 개발하였다. 전체적인 바이오매스와 지방산 생산성을 높이기 위해서는 MTAP-1 배지가 적합하여 바이오매스 생산성과 지방산 생산성은 기존의 TAP 배지 대비 각각 14%, 45% 증가하였다. 생리 활성 효과로 인해 관심도가 높은 오메가-3 지방산의 생산에는 MTAP-4 배지가 가장 적합하여 바이오매스 생산성과 오메가-3 지방산 생산성이 기존 BBM 배지 대비 각각 18%, 39% 증가하여 목표 중점 생산물질(바이오매스, 총 지방산, 또는 오메가-3 지방산)의 생산성을 향상시킬 수 있는 신규 배지 2종의 조성을 개발하였다. Parachlorella sp. is an efficient fatty acid producer that can be used in the production of biofuels, feeds, and fertilizers. Microalgae show varying responses to culture conditions, even those within the same species. In this study, growth and fatty acid composition of a newly isolated Parachlorella sp. from the Nakdong river of Korea in different culture media were investigated. The microalga was cultivated in 400 ml bubble column photobioreactors using BG-11, BBM, TAP, and modified TAP (MTAP) media. It was shown that using BBM led to greater fatty acid accumulation (34%), while using TAP medium led to greater biomass productivity (0.34 g/l/day). Composition of the TAP medium was modified to have the N:P ratio of BBM while also varying concentrations of N and P to improve fatty acid productivity. One of the modified TAP media, MTAP-1 (104.8 mgN/l, 135.2 mgP/l, N:P ratio = 0.77), showed the highest fatty acid concentration of 0.69 ± 0.04 g/l, while those from TAP and BBM were 0.48 ± 0.06 g/l and 0.40 ± 0.02 g/l, respectively. The results showed that microalgal fatty acid productivity could be enhanced by changing the N:P ratio and concentrations.

방재분야에서 가장 발달된 장비와 과학기술을 이용하여 많은 연구개발이 이루어져서 재산 피해를 줄이고 인명을 구하고 있다. 비록 정부가 방재 분야를 확대하려고 노력해 왔지만, 그 투자 규모와 연구 결과는 국내의 타 과학기술 분야나 선진국의 방재분야에 비해 낮은 수준에 머물러 있다. 그렇지만 재난을 방지하는 국가부처인 소방방재청이 2004년 6월에 설치되어, 여러 가지 재난에 효과적이고 정비된 체계를 갖추게 되었다. 이 연구에서는 정부의 투자비용을 산정하고 방재분야와 관련된 영역을 명확히 규명하였다. 또한 방재에 관한 연구개발에 대하여 정부의 각 부처간에 임무를 분석하여 역할 분담에 대해 논의하였다. 이러한 역할 분담은 정부의 승인 절차를 통하여 공고히 하게 되었다. A number of researches on disaster risk reduction using the most advanced equipments and scientific technologies have been performed to minimize the damage of property and to protect human life. Although the Korean government is trying to enlarge the research area for disaster risk reduction, the investment size and the applicable results in this area have stayed in the lower level comparing to other scientific fields in Korea and the same field in advanced countries. However, the National Emergency Management Agency (NEMA), a government Agency which is responsible for disaster management coordination, was established in June 2004 establishing an efficient and well-organized system to cope with various disasters. In this study, investment size by the government was evaluated and associated areas were also identified. We also analyzed the roles on research and development for disaster risk reduction among different government Ministries were analyzed and role assignment to each Ministry was proposed. The role assignment has been concreted by conducting the process of approval in the government.

추적조사에 의한 농촌 여성의 출산력과 임신소모율

박정한,김신향,천병렬,김귀연,예민해,조성억,조재연,Park, Jung-Han,Kim, Sin-Hyang,Chun, Byung-Yeol,Kim, Gui-Yeon,Yeh, Min-Hae,Cho, Seong-Eok,Cho, Jae-Yeon 대한예방의학회 1988 Journal of Preventive Medicine and Public Health Vol.21 No.1

농촌 여성들의 출산력과 임신소모율을 조사하기 위해 군위군에 거주하는 15-49세의 여성 가운데 조사시작 당시 영구불임 수술을 하지 않은 유배우 가임여성을 대상으로 17명의 면 보건요원들이 1985년 4원 1일부터 1987년 3월 31일까지 2년간 추적 관찰하여 그들의 피임 실천율, 출산율 그리고 임신 소모율을 조사하였다. 총 관찰된 6,826 여성인년 가운데 피임을 실천한 기간은 3,522인년(51.6%), 임신, 유산 그리고 출산을 한 기간은 519인년(7.6%)이었으며 피임을 하지 않은 기간은 2,491인년(36.5%)이었다. 조사시작 당시에 영구불임 수술을 한 사람을 포함시켰을 경우에는 피임을 실천한 기간이 72.1%로 전국의 피임 실천율보다 오히려 높은 수준이었다. 그러나 30대 여성의 경우 2-3명의 자녀를 갖고서도 피임을 하지 않고 있는 사람이 약 28%나 되고, 피임을 하는 경우에도 월경 주기법이나 콘돔과 같은 실패율이 높은 피임법을 20대 여성보다 더 많이 쓰고 있었다. 관찰기간 동안 전체적으로는 100 여성인년당 14.3건의 임신이 일어났으며, 25-29세 여성 이 100 여성인년당 27.4건의 임신으로 가장 높은 임신율을 보였다. 전체임신 중 22.0%가 사산(0.9%), 자연유산(3.8%), 그리고 인공유산(17.3%)으로 소모되었다. 연령이 증가함에 따라 임신 소모율이 증가하여 30세 미만 부인의 임신 소모율은 15.8%인데 비해 30대 여성이 임신을 한 경우 37.5%가 인공유산을 하여 자연유산과 사산을 합한 임신 소모율이 43.5%나 되었다. 추적기간 동안에 인공유산으로 종결한 부인이 출생으로 종결한 부인에 비해 평균 자녀수와 자연유산 및 인공유산 경험회수가2배 이상으로 많아 유산을 경험한 사람이 유산을 반복하고 있었다. 출생으로 종결한 임부는 평균 4.2회의 산전 관리를 받았고 분만은 85%가 의료기관에서 일어났으며, 가정 분만은 15%로 전국의 농촌지역에 비해 높은 시설 분만율을 나타냈는데, 이것은 군위군이 일차 보건의료시범사업 지역이었기 때문으로 생각된다. 이와 같은 연구 결과로 보아 농촌 여성을 대상으로 한 가족계획 사업은 30대 여성을 대상으로 하여 경구 피임약이나 자궁내장치와 같이 피임 효과가 높은 피임법을 보급하는데 중점을 두어야 임신 소모율을 줄이고 여성건강을 증진시킬 수 있을 것으로 생각된다. To measure the fertility rate and pregnancy wastage of women in rural area, 3,780 married women under 50 years old who were not sterilized either woman or husband in Gunwee county were followed up for 2 years. Seventeen Myun health workers visited these women periodically to check the status of their family planning practice and menstruation. Pregnant women were interviwed for their past obstetric history and followed up to the time of delivery. Family planning was practiced in 51.6% of the 6,826 women-years observed during the period from April 1, 1985 to March 31, 1987. Pregnancy, abortion and delivery covered 7.6% of the observed women-years and family planning was not practiced in 36.5% of the women-years. When sterilized women at the beginning of the study were included, the family planning practice rate was 72.1% which was slightly higher than the national family planning practice rate. However, 28% of the women of 30-39 years old had not practiced family planning although they had 2-3 children and they used more such less effective methods as safe-period method and condom than the women of 20-29 years old. Overall pregnancy rate was 14.3 per 100 woman-years. Women of 25-29 years old had the highest pregnancy rate of 27.4 per ,100 woman-years. Pregnancy wastage including spontaneous and induced abortions and still births was 22.0% of all pregnancies and it increased with the age of women; 15.8% in women less than 30 years old and 43.7% in women of 30 years and over. Women who terminated the pregnancy with induced abortion had more pregnancies, more previous induced and spontaneous abortions and shorter pregnancy interval than those women who terminated with live birth. Pregnant women terminated with a live birth had received 4.2 prenatal cares on the average. Eighty-five percent of deliveries occurred at a medical facility and 15% at home which was substantially lower home delivery rate than the other rural area of Korea. This may be due to the effects of the demonstration project for the primary health care in 1970s in Gunwee county. These findings suggest that family planning service in rural area should be strengthened by promoting the use of more effective contraceptive method among women over 30 years of age.

Sclerosing angiomatoid nodular transformation (SANT) is a rare, benign vascular neoplasm. Most patients have no clinical symptoms, and the tumors are usually discovered incidentally on abdominal computed tomography or ultrasonography. Some studies have reported the clinical features and imaging findings of SANT, but the diagnosis is based on histopathologic examination of a tissue specimen obtained at splenectomy. We report herein an incidentally discovered case of SANT and review the related literature.
