  • We performed post-operative hemodynamic evaluation and lung perfusion scan after left lung transplantation in dog. The heart & lungs were extracted from donor dog while the both lungs were flushed with 4oC Euro-Collin`s solution after heparinization & infusion of prostaglandin E1.In the recipient dog, anastomosis of the left atrial cuff was performed by continuous 4-0 Prolene everted suture, and bronchial anastomosis by telescope method with 4-0 Prolene continuous suture. The end-to-end anastomosis of left main pulmonary arteries was performed with continuous 6-0 Prolene suture. After closure of left thoracotomy incision, the lung perfusion scan was performed post operative 2 days for evaluation of the function of the transplanted lung which showed good perfusion. The dog was sacrificed in the post-operative 5 days for autopsy.

  • The post-antibiotic effects (PAE) of DW-116 were evaluated against Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 27348, Staphylococcus aureus ATCC 25923 , Escherichia coli ATCC 25922 and Pseudomonas aeruginosa MB4-16, repectively. Against gram-positive bacteria, PAEs of DW-116 were longer duration (20-35 min) than those of rufloxacin(1O-20 min), and shorter than those of ciprofloxacin (50-90 min). Especially, against E. coli, DW-116 and ciprofloxacin obtained approximately 3 hrs of PAES.

  • An experimental study for characteristics of soot were conducted at the post-flame region in jet diffusion flames, where carbon dioxide was used as additives in oxidizer stream. Light-extinction method was performed using He-Ne laser with wave length at 632.8nm for the measurement of relative soot density and soot volume fraction with dimensionless extinction coefficient, $K_e$ and mass specific extinction coefficient, ${\sigma}_s$. To increase of resolution, laser light was modified for sheet-form using concave, convex lenses and slit. C/H ratio was introduced for quantitative analysis of soot growth which is expressed by carbonization and dehydrogen. Also transmission electron microscopy(TEM) was used for observation of morphological shape. The results show that the relative soot density in the post-flame region was lower when carbon dioxide was added in oxidizer stream because of reduction of flame temperature.

  • The ruthenium(II) ferrocenyl heterocyclic thiosemicarbazone complexes of the type $[RuCl(CO)(EPh_3)]_2L$ (where E = P/As; L = binucleating monobasic tridendate thiosemicarbazone ligand) have been investigated. Strutural features were determined by analytical and spectral techniques. Binding of these complexes with CT-DNA by absorption spectral study indicates that the ruthenium(II) complexes form adducts with DNA and has intrinsic binding constant in the range of $3.3{\times}10^4-1.2{\times}10^5M^{-1}$. The complexes exhibit a remarkable DNA cleavage activity with CT-DNA in the presence of hydrogen oxide and the cleavage activity depends on dosage.

  • The evaluation of diagnostic tests attempts to obtain one or more statistical parameters which can indicate the intrinsic diagnostic utility of a test. Sensitivity. specificity and predictive value are not appropriate for this use. The likelihood ratio has been proposed as a useful measure when using a test to diagnose one of two disease states (e.g. disease present or absent). In this paper, we generalize the likelihood ratio concept to a situation in which the goal is to diagnose one of several non-overlapping disease states. A formula is derived to determine the post-test probability of a specific disease state. The post-test odds are shown to be related to the pre-test odds of a disease and to the usual likelihood ratios derived from considering the diagnosis between the target diagnosis and each alternate in turn. Hence, likelihood ratios derived from comparing pairs of diseases can be used to determine test utility in a multiple disease diagnostic situation.

  • We fabricated a Li-S battery with post-treated carbon nanotube (CNT) films which offered better support for sulfur, and investigated the effect of the surface properties and pore structure of the post-treated CNT films on Li-S battery performance. Post-treatments, i.e., acid treatment, unzip process and cetyltrimethylammonium bromide (CTAB) treatment, effectively modified the surface properties and pore structure of the CNT film. The modified pore structure impacted the ability of the CNT films to accommodate the catholyte, resulting in an increase in initial discharge capacity.

  • Increasing the user's need in the building facilities, the architects, engineers, and building managers must consider the user's opinion when they plan and construct the buildings. When planning and managing of the buildings, accepting the user's opinion is desirable and indispensible to solve the Problems about the architectural facilities between suppliers and users. To supply the efficient working environments, use the check listing tools and operate the post occupancy evaluation. The real estate and development company is selected for the evaluation. It is renovated in 2000 to fit in its working environment. The process of the evaluation is proceeded both private and group working spaces and facility and management of the buildings with 10 categories. Following the result of Post occupancy evaluation, the users of the building are mostly satisfied with their working environments after the renovation. However, the categories in thermal environment and indoor air and supply for office work need to be improved in advance.

  • This study examined the add-on efficacy of eye movement desensitization and reprocessing (EMDR) therapy among adult civilians with post-traumatic stress disorder (PTSD) who continued to be symptomatic after more than 12 weeks of initial antidepressant treatment. Scores for the Clinician Administered PTSD Scale (CAPS) were rated pre- and post-EMDR and at a 6-month follow-up. After an average of six sessions of EMDR treatment, seven of 14 patients (50%) showed more than a 30% decrease in CAPS score and eight (57%) no longer met the criteria for PTSD. Our results indicate that EMDR could be successfully added after failure of initial pharmacotherapy for PTSD.

  • Developmental anomalies of internal carotid artery (ICA), being rare entities, are mostly asymptomatic by themselves because of good collateral supply. However, when present with other associated intracranial anomalies requiring treatment, there can be catastrophic consequences, if special attention is not paid to this condition. We present a case of 36 years old male, who reported to our emergency department with complaints of headache and loss of consciousness. He was diagnosed as a case of ruptured anterior communicating aneurysm with subarachnoid hemorrhage and agenesis of left ICA with trans-cavernous anastomosis. He underwent clipping of aneurysm and was discharged uneventfully. This report highlights the importance of skillful microsurgical clipping in extremely high-risk conditions, in contemporary era of hybrid neurosurgeons.

  • This study was aimed for bettering productivity and technical level of the dental 1 aboratory, and helping the dental technician's benefits and rights, and then endowing them some belonged atmospher and stability on their post by Improving job- satisfaction and maintaining the transferability of one's post at a proper limitation. Therefore, 320 dental technicians extracted randomly from all the technicians working at 494 dental laboratories were subjected for this study. The approach to the study was a way through some postal questionaires executed from March 29, 1988 until May 4, the same year, in which total 254 technicians answered, showing 79% resp"nserate. responserate. The data-analysis was done by a model of the dental technician's transferability from their post, as considering Mobley's(1978)-model of post-transferability, and results through the study are as follows : 1. Satisfaction at a given post showed that the married is better than the unmarried(<0.05), and the experienced is better than the inexperienced(P<0.01). 2. Age, sex, educational experience, and one's service-duration did not affect significantly to the respondent's satisfaction on their post, statistically. 3. Satisfaction at a given post differed in adccordance with given conditions of one's post, i. e.,it stowed high when the monthly payment was good(P<0.05), and when too much duty on their job was given, it was the worst as shown in an example of the next order, too much
