Mo¨ssbauer 분광법에 의한 Mg-Cd 페라이트계의 자기적 성질 연구

In this study, the magnetic properties of Mg_(1-X)Cd_(X)Fe₂O₄ ferrite system has been studied by Mo‥ssbauer spectroscopy. All the samples, prepared by a ceramic sintering method, were found to be single phase spinel by X-ray diffractometry. The Mo‥ssbauer spectra. for x<=0.3, show two magnetic hyperfine splittings. one due to Fe^3+ octahedral site ions and the other due to tetrahedral site ions. While for x=0.4 spectrum shows relaxation behaviour and for x>=0.5 it exhibits quadrupole splittings. This result implicates that the magnetic properties of Mg_(1-X)Cd_(X)Fe₂O₄ferrite system change from ferrimagnetics to paramagnetics as increasing x, And the x, Cd content, dependence of Mo‥ssbauer parameters (isomer shift, quadrupole splitting, magnetic hyperfine field and line width) were investigated.

Purpose : The purpose of this survey was to investigate the effect on job satisfaction and organizational commitment according to the job types of Pusan area physical therapists figuring out structural causality between job satisfaction and organizational commitment. Method : This survey was conducted through structured questionnaire for the physical therapists working in Pusan area, and data from 217 therapists were utilized in the final analysis. Data collection was deployment questionnaire using Google Docs (online survey), The SPSS 21.0 program was used according to for research purposes independent t-test was used for individual and job characteristics, was used according to job types and job satisfaction and organizational commitment are logistic regression analysis, correlation analysis and chi-square test. Result : The results of this study were as follows. 1. Overall job satisfaction according to the job types was appeared musculoskeletal physical therapist more 4 times. 2. Job types according to the organizational commitment did not make direct effect. Conclusion : Number of musculoskeletal physical therapist than neurological physical therapist was fewer and there were many per day treatment of patients, but overall job satisfaction was appeared that is higher. This is thought that job types affects more than working environment.

Surgical resection remains as the treatment of choice for non-small cell lung cancer (NSCLC) in early stage. Despite some patients with inadequate respiratory reserve, cardiac dysfunction, vascular disease, or other medical co-morbidities are unable to tolerate the stress during surgery or postoperative period. The need for less invasive alternative therapy has increased. Filling up the need, radiofrequency ablation (RFA) plays a key role in improving and replacing the existing therapies including surgery or chemotherapy. Recent studies have shown that lung RFA is one of the most reliable alternative therapeutic tool for all the stage of lung cancer. Long term follow-up data of pulmonary RFA in terms of safety and efficacy have rarely reported. In fact, there was no report of complete remission (CR) achieved by RFA in advanced lung cancer. We reported a case of achievement of complete remission state for ten years by RFA combined with adjuvant chemotherapy for advanced stage of lung cancer.

Melanoma is a cutaneous malignant neoplasm of melanocytes. Primary malignant melanoma (MM) of the lung is very rare. Although previous reports have described the radiologic features of pulmonary MM, its rarity makes the issues still unknown. Furthermore, there is little information regarding diagnostic application and/or usefulness of [18F]-fluorine-2-fluoro-2-de-oxy-D-glucose positron emission tomography (FDG-PET)-computed tomography (CT). Herein, we introduce a primary MM of the lung with multiple metastases, focusing on the radiologic imaging including PET-CT imaging. The pulmonary mass was presented as a round, well-demarcated, and multi-lobulated mass with an increased uptake of FDG on PET-CT images.

Encephalomyocarditis(EMC) virus was isolated from the mummified and stillborn pigs at a swine farm in Chonnam Province, experienced with EMC infection over the period Oct.~Dec. of 1989. In addition some cultural, serological properties of the isolates and experimental infections in the piglets were studied. The results obtained were as follows; 1. Two EMC virus strains with HA titers and CPE similar to EMC-ATCC were established in a baby hamster kidney (BHK)-21 cell line by inoculating homogenates of brain and heart of the 19 mummified or stillborn pigs and designated $K_3$ and $K_{11}$. 2. At the second BHK-21 cell line passage of the initial isolates CPE appeared after incubation for 16~18 hours, while at the fourth and fifth passage the highest titer of HA was recorded, titer of HA using rat and guinea pig erythrocytes. 3. One pig inoculated with the isolate $K_3$ showed dyspnea as clinical signs and died at the 10 days after inoculation at necropsy white necrotic foci were observed from the dead animal heart. 4. Although all the rest surviving pigs showed increases in antibody titer and body temperature of $40^{\circ}C$ above for the initial 2~4 days followed by the return to normal, there were no gross lesions when the animals were sacrificed at the 2 weeks after inoculation.
