Pulmonary sequestration is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and receives its blood supply from an anomalous systemic artery. Extralobar form is a very rare congenital malformation. We have experienced a 54 year old female patient with a mass in the upper lobe complaining of cough and blood tinged sputum. A triangular shaped mass was located in the left upper lobe, medially. The arterial blood supply were from the thoracic aorta and the pulmonary artery but there was no the tracheobronchial communication. The venous drainage was through the pulmonary vein. The mass was confirmed as extralobar pulmonary sequestration associated with a pericardial defect.

We reviewed 10 cases of traumatic diaphragmatic injuries at Soonchunhyang University Gumi Hospital from January 1990 through April 1993. seven patients were male and three patients were female. The age distribution was ranged from 25 to 79 years, predominant 4th decades occurred in male. The traumatic diaphragmatic injuries were due to blunt trauma in 9 cases (traffic accident 7 and crash injury 2) and penetrating wound in 1 case (stab wound). The common symptom were dyspnea (60%), chest pain and abdominal pain in order frequency. In the blunt trauma and crash injury, te rupture site was all located in the left(9 cases). In the penetrating wound, the rupture site was located in the right(1 case). The surgical repair of 10 cases were performed with transthoracic approach in 9 cases and thoracoabodominal approach in 1 case. The postoperative mortality was 10% (1/10). The cause of death was multiple organ failure with pulmonary edema.

This study is aimed to establish the evaluation model for the satisfaction and demand for expansion related to Driving Assistance Center of the Disabled using Multidimensional Analysis of Preference Data and to analyze an effect of the assistant policy on getting a driver’s license for the disabled. The results are as follows. First, in the evaluation model, the proportion of variance of 1 dimension and 2 dimension took 69.4% of the total. And the average change of R2 changed most from 47.3 to 69.4 in the explanatory degree of 2 dimension. Therefore, it was determined that the value of 2 dimension could be the optimum solution. Third, when this model was illustrated in diagram, it was shown that I group of the subject of evaluation were well positioned with 1 group of the attribute of evaluation, Ⅱ group of the subject of evaluation were well positioned with 2 group of the attribute of evaluation, Ⅲ group of the subject of evaluation were well positioned with 3 group of the attribute of evaluation and Ⅴ group of the subject of evaluation were well positioned with 4 group of the attribute of evaluation respectively. Therefore, the system (98.3%) except 2 cases of Ⅳ group of the subject of evaluation well represented the a direction of evaluation, which means it has high degree of correspondence with the evaluators’ opinions on the satisfaction and demand for expansion with the Driving Assistance Center of the Disabled. Judging from these findings, it is known that evaluators' opinions should be more reflected in analyzing the effect of the assistant policy of getting a driver’s license of the people with severely disabilities. In addition, it is required that consistent studies be conducted that compare the evaluation of reflection of the evaluators and the assistant policy of getting a driver’s license of the disabled. Furthermore, to reinforce the public functions of public authority, the functions of the Driving Assistance Center of the Disabled should be added and expanded more.

Purpose: The purpose of this study was to identify cognitive function, upper limb function, and activity of daily living according to characteristics of stroke patients. Methods: The study was a cross-sectional and descriptive design. 102 hemiplegic patients less than 90 day after stroke were recruited from October 1, 2009 to April 30, 2010. The data were analyzed using descriptive statistics, t-test, and ANOVA. Results: Participants showed 21.04(SD=7.05) score of MMSE-K, 14.56(SD=9.42) score of upper limb function, and 53.87(SD=31.38) score of activities of daily livings. Participants with brainstem and cerebellum lesion had higher cognitive function than with right and left hemisphere lesion. An unaffected upper limb function among men and those under age 49 had higher score than other groups. There was shown higher score of affected upper limb function among those with cerebral infarction than cerebral hemorrhage. Conclusion: In early stage of rehabilitation, stroke patients had moderate cognitive dysfunction, severe affected upper limb dysfunction, and severely dependent state of activities of daily livings. For enhancing cognitive function and upper limb function, post stroke patients should be provided nursing care that considered not only cause of disease and location of brain lesion but also gender and age.

Because the use of software in automotive industries is growing constantly as vehicles are rapidly getting more complicated to adopt advanced technologies and supplementary functions, the quality of software has been a critical factor for the quality of automotive parts, and the vehicle also. But owing to the nature of software, the software quality assurance system should be different from that of hardware, and usually based on the quality models like ISO-9001, CMMI, or SPICE, which was developed for software. We have developed the CMM Level2 based standard software process, MSDP consists of planning, requirements management, process tracking, quality assurance and so on and implemented it to development, testing, and maintenance of chassis control systems like ESP, CDC, MOPS and others. We could reduce much more defects in the earlier development phase than before by complying the newly made standard process and auditing the software related activities with quality assurance system. Furthermore, we are continuously revising the standard process to be more effective for quality control and to be CMMI Level3 compliant.

It requires to make the safety education not a merely formal education but as a practical one for the factor of safety on the industrial environment. We surveyed the workers who are working for a power plant-related small and medium sized businesses around Incheon about the necessity of safety education to improve the safety awareness for themselves. The answered workers for the survey are numbered 198, and we can analyzed those questionnaires by using SEM(Structural Equation Modeling). We ran the analysis by the tool of statistics, AMOS19.0. We examined the basic hypothesis that self-efficacy, safety education, and perceived safety influenced on the will for the safety on the job through the attitude of safety on the work as a parametric cause. We can derive a result that self-efficacy and education about safety makes an effect not only on the will for the safety directly, but also through the attitude and perceived safety. Perceived safety does not influenced on the attitude of safety on the work. Education, attitude, and perceived safety show positive influential factors, but self-efficacy represents negative effect directly on the will for the safety. Safety eduction makes more positive effect on the attitude and perception of the safety, and it shows the necessity for the reinforcement.
