The age- and gender-related differences in acute toxicity and opening of blood-brain barrier induced by an organophosphate soman were investigated in rats. To assess acute toxicity, young (7 weeks old) and old (12 weeks old) male and female rats were subcutaneously administered with various dose levels of soman.(omitted)

There are many problems for the rural old peoples who to use the rural houses practically with physical and mental disabilities to make use of them because the rural houses have a tendency to look alike the urban houses. Today the rural old peoples are treated distantly by the boundary of national reserved power to make and activate their facilities, the shortness of their economically surplus power and the absence nationally social security system in spite of their physical and mental disabilities. So it is necessary for us to remodel symmetrically their rural houses to fit their physical and mental disabilities to spend comfortable living and to develop structure remodeling programs and space reorganization programs of the rural handicapped old peoples' houses to support independent life to correspond with their physical and mental disabilities.

Objectives: Pine needles are used as passive air samplers (PAS) of atmospheric persistent organic pollutants (POPs). This study was carried out in order to investigate whether pine needles can also be used as a PAS of polybrominated diphenyl ethers (PBDEs). Methods: PBDEs in one to three year-old pine needles were analyzed with HRGC/HRMS. Results: PBDEs in the atmosphere were accumulated in the pine needles. The rate of increase in concentration of lower substituted PBDEs (tri- through hepta-) in pine needles was linear. The rate of increase of the higher substituted PBDEs (octa- through deca-) was also liner, but only up to two year-old pine needles. The concentration did not increase further in older pine needles. Conclusion: Therefore, it can be concluded that young pine needles, those that are two years old or less, are recommended for use as PAS of atmospheric PBDEs.

본 연구의 목적은 노년기 연령집단별로 사회활동 참여유형이 다른지와 연령집단별로 행복감에 미치는 사회활동 유형은 무엇인지를 조사하는 것이다. 한국고령화패널연구(KLoSA), 5차(2014) 자료를 활용하였으며 5차 시점에서 65세 이상이면서 자녀와 동거하지 않는 노인 3,273명을 대상으로 교차분석, 일원변량분석, 위계적 다중회귀분석(hierarchical multiple regression analysis)을 실시하였다. 연구결과, 경제활동 참여 비율은 연령대가 높아질수록 낮아졌으며, 여가활동은 연소노인이 중고령노인이나 초고령노인집단에 비해 참여수준이 높았다. 가족활동은 연소노인에 비해 중고령노인이나 초고령노인 집단에서 참여수준이 높았고, 그 외의 친목활동과 종교활동은 연령 집단 간 참여수준의 차이를 보이지 않았다. 연령집단별 행복감에 유의미한 영향을 주는 사회활동 유형을 회귀분석 한 결과, 연소노인 집단에서는 경제활동을 제외한 여가활동, 친목활동, 종교활동, 가족활동이 노인의 행복감에 정적으로 유의미한 영향을 미쳤으나, 중고령노인 집단에서는 친목활동과 가족활동이, 초고령집단에서는 가족활동만이 노인의 행복감에 정적으로 유의미한 영향을 미쳤다. 본 연구결과는 연령집단에 따라서 참여하는 사회활동 유형과 그 영향력이 달라질 수 있음을 입증하였다. 본 연구는 다양화되어가는 노인인구의 욕구를 경험적으로 검증하였다는데 그 의의가 있다.

옛한글로 저술된 자료는 활자 인쇄본, 목판 인쇄본, 필사본, 고소설, 서간 등 방대한 자료가 한국학중앙연구원 장서각을 비롯하여 많은 기관에 소장되어 있다. 옛한글을 전산정보화하기 위해서는 수작업에 의한 '입력'과정이 필요하다. 옛한글 문서의 전자문서화 작업이 오랫동안 진행되어 왔으나 옛한글을 전공한 연구자 개인의 노력으로 옛한글을 읽고 입력하여 전자자료화되고 있는 실정이다. 연구자의 숙련도가 개인적인 작업능력의 향상에 머무르고 기술의 축적으로 이어지지 못한다. 현재까지 극히 일부분의 옛한글 문서만이 소개되고 대부분의 자료는 수장고에 보관되어 있는 상태이다. 어렵게 전자문서화된 옛한글 고문서도 전자기기 간의 호환성 문제로 정보 공유 및 표시에도 어려움이 있다. 옛한글 문서의 전자문서화의 작업효율을 높이고 전자문서화 기술의 축적을 위해서는 옛한글의 입력, 표시, 저장 방법의 개선을 비롯하여 옛한글 문서의 이미지 분석을 통한 광학적 문자인식(OCR)의 개발이 필요하다.

노년기에는 의사소통의 전체적인 맥락을 해석할 때 표면적으로 드러나는 단서에 주로 의존하게 되면서, 함축적이고 우회적인 표현인 비유언어를 처리하는 능력이 저하된다. 따라서 의사소통 시, 타인의 의도를 효과적으로 이해하고 자신의 의사를 전달하는 데 어려움을 보일 수 있다. 본 연구는 정상 청년층 50명과 정상 노년층 50명을 대상으로 비유언어의 하위영역인 직유 은유 관용어 속담 이해 과제를 실시하여 노화에 따른 비유언어 처리능력의 특성을 확인하고자 하였다. 과제는 제시되는 전체적인 내용과 적합한 비유언어를 보기문항 중에서 선택하도록 하였다. 분석 결과, 첫째, 노년층은 청년층에 비해 모든 비유언어 하위 과제에서 더 저하된 수행력을 보였다. 둘째, 노년층은 비친숙한 관용어와 속담 이해과제에서 더 저하된 수행력을 보였다. 셋째, 노년층은 문자 그대로의 의미에 국한하여 문항을 이해하는 양상을 빈빈히 보였다. 노년층은 특정 상황 맥락에 맞게 효과적인 의사소통을 할 수 있는 능력인 화용언어 능력과 더불어 내포된 의미를 추론하는 능력 및 문자 그대로의 의미와 같은 표면적인 단서를 억제할 수 있는 능력이 저하될 수 있다. 이러한 결과는 노화로 인하여 일상의 의사소통 상황에서 화자의 내포된 의미를 이해하는 것에 어려움을 보일 수 있음을 시사한다.

In order to improve the refresh rate of old newspaper(ONP), PCC shape-controlling experiments were carried out. The effect of a PCC polymorph on improving the quality of old newspaper was studied for a transformation from waste paper to eco-friendly paper. The synthesis of PCC consists of an in-situ process and a loading process to enhance the refresh rate of old newspaper. The characteristics between the in-situ process and the loading process could be analysed by SEM analyses of coated fiber surfaces. The retention rate ranges from 65 to 67% after the application of the in-situ process, and that after the loading process ranges from 55 to 58%. The retention rates thus show a difference of about 7-10%. In addition, the whiteness and ERIC characteristics of the in-situ process gave more efficient results than those of the loading process.

As the tendency of children's overdependence on smart phones increased, it was obligatory to carry out preventive education more than once a year in kindergarten and day care center, but there is no specific guidance on contents and method of preventive education. This is due to the lack of prior studies on the actual use of smartphones and the influence variables of infants and young children. The purpose of this study was to investigate the effects of use time, frequency of use, and sociological background variables on the actual situation of smartphone usage and overdependency on smartphone among 3-5 year old children nationwide. For the analysis, the frequency of the use of smartphone for 3-5 year old children was analyzed by frequency analysis, and the influence variables were correlated and multiple regression analysis. Research shows that smartphone overdependence of 3-5 year old children have an influence on the use time and frequency of use. The results should include content that restricts the use time and frequency of use of smartphones and prevention education programs for 3-5 year olds and young children. Suggesting a need for a transition to the educational method used.

Objective: The purpose of this study was to analyze the risk factors of the musculoskeletal workload of mid-old-age female caregivers by identifying work postures and subjective symptoms. Method: This study was carried out on a total of 206 subjects 206 mid-old-age caregivers(45~65 years old) from November 2009 to April 2010: 206 mid-old-age caregivers (45~65 years old) at the long-term hospital. A questionnaires survey on general factors and subjective symptoms of subjects was conducted. The risk factors of the musculoskeletal workload evaluation method is based on OWAS, RULA, REBA according to occupation properties. Results: The analysis of the rates of the subjective symptoms showed that 78.6% subjects experience low back pain. The analysis of the work type showed that transfer is the highest rate(36.3%) and position change is the second(18.2%). The analysis of the work postures showed that the thrusted back with twisting position over $20^{\circ}$ is highest rate(37.4%), the bended back forward with twisting position is the second(27.5%). Conclusion: This study suggested that the need of preventive education for caregivers and workload improve. It is hoped that subsequent study on the difference of subjective symptoms between educated caregivers and non educated caregivers will be conducted.
