Purpose: The purpose of the study was to analyze the changes in functional status and caregiver burden after a community based case management program for stroke patients. Method: This study was designed as a one group pre and post test. A total of 61 stroke patients and their caregivers were sampled in three urban areas and two rural areas. Face to face interviews were conducted as a pre test one week before intervention, and a post test two weeks after intervention. The case management program consisted of four home visits and two telephone counseling sessions for assessment, education and providing information during the eight weeks. The collected data were analyzed with paired t test. Results: First, significant differences in functional status, and specifically mobility and cognition, were found between pre test and post test. Second, caregiver burden, in particular, objective burden was significantly decreased after 8 weeks. Third, the positive response for the services increased after 8 weeks. Conclusion: The community based case management program was effective to improve the functional status of stroke patients and to decrease the caregiver burden.

Edible offal is easily contaminated by Escherichia coli (E. coli) and fluoroquinolone (FQ)-resistant E. coli is considered a serious public health problem, thus, this study investigated the genetic characteristics of FQ-resistant E. coli from edible offal. A total of 22 FQ-resistant E. coli isolates were tested. A double mutation in each gyrA and parC led the highest MIC. Four (18.2%) isolates carried plasmid-mediated quinolone resistance genes. The fimH, eaeA, escV, astA, and iucC genes were confirmed. Seventeen isolates (77.3%) were positive for plasmid replicons. The isolates showed high genetic heterogeneity based on pulsed-field gel electrophoresis patterns.

Since its discovery in 1991, the carbon nanotube has attracted much attention all over the world; and several method have been developed to synthesize carbon nanotubes. According to theoretical calculations, carbon nanotubes have many unique properties, such as high mechanical strength, capillary properties, and remarkable electronical conductivity, all of which suggest a wide range of potential applications in the future. Here we report the synthesis in the catalytic decomposition of acetylene at ~65 $0^{\circ}C$ over Ni deposited on SiO2, For the catalyst preparation, Ni was deposited to the thickness of 100-300A using effusion cell. Different approaches using porous materials and HF or NH3 treated samples have been tried for synthesis of carbon nanotubes. It is decisive step for synthesis of carbon nanotubes to form a round Ni particles. We show that the formation of round Ni particles by heat treatment without any pre-treatment such as chemical etching and observe the similar size of Ni particles and carbon nanotubes. Carbon nanotubes were synthesized by chemial vapour deposition ushin C2H2 gas for source material on Ni coated Si substrate. Ni film gaving 20~90nm thickness was changed into Ni particles with 30~90nm diameter. Heat treatment of Ni fim is a crucial role for the growth of carbon nanotube, High-resolution transmission electron microscopy images show that they are multi-walled nanotube. Raman spectrum shows its peak at 1349cm-1(D band) is much weaker than that at 1573cm-1(G band). We believe that carbon nanotubes contains much less defects. Long carbon nanotubes with length more than several $\mu$m and the carbon particles with round shape were obtained by CVD at ~$650^{\circ}C$ on the Ni droplets. SEM micrograph nanotubes was identified by SEM. Finally, we performed TEM anaylsis on the caron nanotubes to determine whether or not these film structures are truly caron nanotubes, as opposed to carbon fiber-like structures.

목적: 본 연구는 전정감각과 고유감각 제공을 기초로 한 감각통합치료를 통해 아스퍼거 아동의 전정 고유감각 처리 능력에 미치는 효과를 알아보고자 하였다. 연구방법: 연구대상은 P시에 거주하는 만 11세 2개월 된 남아로, 8세되던 해에 아스퍼거로 진단받았다. 본 연구는 개별 실험 연구 중 AB설계를 사용하였다. 실험과정은 기초선 기간(A) 3회, 중재 기간(B) 8회로 진행되었다. 기초선 기간에는 감각통합치료를 실시하지 않았으며, 중재기간에는 전정감각과 고유감각 제공을 기초로 한 감각통합치료를 실시하였다. 전정 고유감각 처리는 자세 조절 능력의 기초를 형성하므로 자세 조절 능력을 알아보기 위해 테이블 활동 후 아동의 앉은 자세 변화와 복와위 신전 자세를 평가하였다. 결과: 본 연구의 결과는 다음과 같다. 아동의 앉은 자세 조절 능력과 복와위 신전 자세는 기초선 기간과 비교하여 중재기간에 대부분 2 표준편차 이상으로 향상되었다. 따라서 전정감각과 고유감각 제공을 기초로 한 감각통합치료가 아스퍼거 아동의 전정 고유감각 처리능력 향상에 효과적이었다. 결론: 본 연구는 아스퍼거 아동이 보이는 감각처리의 어려움을 파악하여 감각통합치료를 접근하고 그 결과를 측정함으로써, 감각통합치료의 질적인 효과를 제시한데 의의가 있다.
