The limit of detection(LOD), pooled coefficient of variation(pooled CV), desorption dffciency(DE), and stability after desorption by pre-treatments was compared and evaluated for analyzing the Ethylene oxide(EO) sampling on HBr-coated Charcoal tube, The results were as follows: 1. The EO's LOD was 2,483ug/sample when using the desorptin solvent, benzene : CS2(99:1), and 1.919ug/sample after using DMF. The result of the sample that passed DMF desorption and was derivativized was 1.301ug/sample. 2. EO's pooled CV was 0.00503 when using the solvent benzene:CS(99:1), after desorption with DMF, the result was 0.00329, and the result of those derivativized by DMF desorption was 0.00514. 3. EO's DE using the solvent benzene:CS(99:1) was 92.13%, atter desorption with DMF, it was 102.75%, and the result of those studied after being derivativized by DMF desorption was 96.47%. 4. EO's stability for the sample with the solvent benzene:CS(99:1), comparing result of next-day analysis to same-day was 96.81% after desorption was 95.69% These results were in accordance with the less than 5% given by OSHA methoc 50. In conclusion, when pre-treatment of the EO in the HBr=coated charcoal, analyzing immediately after desorption by DMF is more simple, precise, and efficient than other analyzing methods, and the stabiity of the sample 24 hours after desorption was alst established.

This study aimed to explore differencesbetween successful and unsuccessful problem-solvers’ representationalcompetence revealed by the solving of twogenetic problems in different presentational modes. Fourhigh school students participated in solving two geneticproblems that contained diverse genetic concepts and requiredcomplex reasoning. Representational competence wasanalyzed with the form of representation, the level ofabstraction and the accuracy of domain knowledge in representation. The student who solved the problem successfully,presented via the verbal mode, selected the appropriateform of representation such as Punnett square and diagramof chromosomes. Her representation showed a high level ofabstraction and accurate domain knowledge. The studentswho solved the problem presented via verbal, graphical, andtable modes constructed the pedigree commonly. Thesuccessful students, however, transformed the original representationinto pedigree so perfectly that it accuratelyreflected the domain knowledge of the original representation. The students used their representation forunderstanding information of the problems, thereby reasoningthe right answers, visualizing and monitoring theproblem-solving process. These findings may provide educationalinsights for educators who seek to understand therelationship between genetic problem-solving processes andrepresentation.

The purposes of this study were to find differences of reflective levels between reflectionin- action and reflection-on-action and to understand the relevance to the PCK components in a biology class. The teacher-researcher was engaged in this study. Every biology class was recorded with a video recorder and reflective PaP-eRs were written, regarding which aspect of the reflective journal the class was combined with. The result of this study was as follows: The major reflective level of reflection-in-action was the technical reflection but that of reflection-on-action were the technical and professional reflections. There were several PCK components regarding at least one reflection in every level of reflection-in-action and reflection-on-action. The reflection of learners and teaching strategies were fused together on the technical level of reflection-in-action. The reflection of learners, teaching strategies and contexts were fused together on the professional level of reflection-on-action. Based on findings we can understand the process of reflection in a biology class and we can develop an understanding of teachers' professional development.

The synthetic, tension-free midurethral sling procedure using transobturator tape (TOT) was introduced in 2001 and has become the most widely used procedure for the treatment of female urinary incontinence worldwide. However, infectious complications associated with erosions have occasionally been reported because of a foreign body reaction to the polypropylene mesh. We observed a case of a bilateral recurrent thigh abscess manifesting 5 years after a TOT sling procedure. The patient had recurrent thigh abscesses with repeated incisions and drainages in the past 1 year. Five months earlier, she had undergone a procedure to remove the eroded suburethral mesh, but incompletely. The right thigh abscess recurred, and ultimately the residual mesh was completely excised with abscess drainage. Complete mesh removal is very important to prevent abscess recurrence, and it is necessary for any urologist treating women who have undergone the TOT procedure to be aware of the possibility of abscesses occurring for a long time after the operation.
농촌 여성노인의 운동유무에 따른 낙상효능감, 낙상위험지각 및 주관적 건강과의 관계

This study was to investigate the relationships among Falls Efficacy Scale, Perception measurement of Fall Risk, and Self-Rated Health according to the Elderly Women's Exercise Habits in the Rural Community. The questionnaires were completed by the Elderly Women aged 65 and older in the Rural Community, and the analysis results of χ2, t-test, and correlations. First, Falls Efficacy Scale and Self-Rated Health according to the exercise habits were significantly higher in the Exercise group than in the Non-exercise group. Second, exercise frequency had positive correlations with exercise time and exercise period in exercise characteristics. Exercise time had positive correlations with Falls Efficacy Scale and Self-Rated Health. Perception measurement of Fall Risk had a negative correlation with Falls Efficacy Scale. Finally, based on the above result, exercise participation has an effect on Falls Efficacy Scale and Self-Rated Health, and there were close relationships among Falls Efficacy Scale, Perception measurement of Fall Risk, and Self-Rated Health. Thus, it is thought that various leasure activities to increase the practice rate in rural elderly women's regular excercise in the rural community. 본 연구는 농촌에 거주하는 여성노인들의 운동유무에 따른 낙상효능감(FES-K), 낙상위험지각(PFR) 및 주관적 건강(SRH)과의 관계를 규명하기 위해 실시하였다. 65세 이상 농촌 여성노인들을 대상으로 설문을 실시하였고 χ2, t-test, 상관관계를 분석한 결과는 다음과 같다. 운동유무에 따른 낙상효능감(p<.05)과 주관적 건강상태(p<.05)는 운동그룹이, 비운동그룹보다 유의하게 높게 나타났으나 낙상위험지각은 두 집단 간에 차이가 나타나지 않았다. 둘째, 운동특성에서 운동빈도는 운동시간(p<.001), 운동기간(p<.001)과 정적 상관관계가 나타났으며, 운동시간의 경우 낙상효능감(p<.05)과 주관적 건강(p<.01)에서 정적 상관관계가 나타났다. 낙상위험지각은 낙상효능감(p<.001)과 부적 상관관계가 나타났고, 주관적 건강은 낙상효능감(p<.001)과 정적 상관관계, 낙상위험지각(p<.01)과는 부적 상관관계를 보였다. 이상의 결과를 볼 때 운동참여는 낙상효능감과 주관적 건강상태에 영향을 주며, 농촌 여성노인들의 낙상효능감, 낙상위험지각 및 주관적 건강이 밀접한 관계가 있는 것으로 나타났으므로 농촌 여성노인의 규칙적 운동의 실천 가능성을 높이는 다양한 여가활동들이 농촌 지역에서 적극적으로 이뤄져야 할 것으로 사료된다.
