In Korea, visiting nursing services in pubic health centers have been in place since 1991. The purpose of this study is to compare the job characteristics, job motivation and job performance between visiting nurses and other public health nurses. 196 subjects were sent mailed questionnaires from Aug. to Sep., 1997. The response rate was 65.3%. Data were analyzed by a SPSSWIN program with a t-test, $X^2-test$, ANCOVA. The results were as follows : 1. The level of job ability in visiting nurses was higher than that of other public health nurses, but it was an insignificant difference(t=1.5975, p=.2078). Among job characteristics, skill variety was significantly higher in other public health nurses(t=8.2121, p=.0046); autonomy and feedback were significantly higher in visiting nurses(t=8.1877, p=.0047/t=7.7026, p=.0085). 2. There was no significant difference in the level of job motivation(t=.6485, p=.4216) and in job performance between the two groups (t=2.7393, p=.0995). In job performance, general nursing and organizational jobs were significantly higher in other public health nurses (t=4.8486, p=.1288/t=9.4237, p=.0024). 3. It was reconfirmed that there was, a significant difference in the level of skill variety, autonomy and feedback in analyzing age and career as covariates. 4. Significant positive relationship was found in job characteristics and job motivation(r=.5488, p=.0000). No significant relationship was found in job characteristics and job performance(r=.0486, p=.498). Through these results, it was supported that there were differences in some of the job characteristics and job performance between visiting nurses and other public health nurses. Therefore, it is requested to redesign job standards, training programs and management styles focusing on the job characteristics of visiting nurses.

As the broadcasting system rapidly migrates to the HD contents production, a broadcasting professional training program has increasingly requested, which provides a professional ability keeping up with new demands and a systematic well-organized education program. This paper utilized a DACUM(developing a curriculum) method for a video editor's job analysis and presented a job model of video editing. With a DACUM job analysis, we retrieved 9 essential job duties and 71 tasks, and then examined their importance, difficulty, frequency, and entry level tasks that are required before job hire. We also established a well-form structure of the job analysis results, completed a DACUM research chart, and consequently built a video editor's job model in TV broadcasting and video production areas. The proposed model is expected to be used as a fundamental material for a future job organization of video editors in TV broadcasting and video production areas, a development of the educational curriculum, and a priority decision of on-the-job training programs.

Electrical impedance tomography (EIT) is a potential supplement for mammogram screening. This study aimed to evaluate and feasibility of EIT as opposed to mammography and to determine pain perception with both imaging methods. Women undergoing screening mammography at the Radiology Department of National University of Malaysia Medical Centre were randomly selected for EIT imaging. All women were requested to give a pain score after each imaging session. Two independent raters were chosen to define the image findings of EIT. A total of 164 women in the age range from 40 to 65-year-old participated and were divided into two groups; normal and abnormal. EIT sensitivity and specificity for rater 1 were 69.4% and 63.3, whereas for rater 2 they were 55.3% and 57.0% respectively. The reliability for each rater ranged between good to very good (p<0.05). Quantitative values of EIT showed there were significant differences in all values between groups (ANCOVA, p<0.05). Interestingly, EIT scored a median pain score of $1.51{\pm}0.75$ whereas mammography scored $4.15{\pm}0.87$ (Mann Whitney U test, p<0.05). From these quantitative values, EIT has the potential as a health discriminating index. Its ability to replace image findings from mammography needs further investigation.

Airworthiness certification of military aircraft is a government's certification that it must have airworthiness and ability to demonstrate its requested function and performance. NATO released STANAG-4671 to establish the minimum airworthiness requirements for UAVs between 150kg and 20,000kg MTOW in 2009. Up to now, there are no clear airworthiness certification criteria and guideline for small UAV which is less than 150kg. STANAG-4671 is used for military UAV airworthiness certification in Korea as Other Airworthiness Certification Criteria. However, since STANAG-4671 requires the same Target Level of Safety without regard to MTOW, excessive Target Level of Safety or design requirements could be applied to relatively small-medium UAV. In this paper, classification and criteria of airworthiness certification for military UAV were investigated and a Target Level of Safety was analyzed based on MTOW using ground victim criteria.

The invention of VHDL(Very High Speed Integrated Circuit Hardware Description Language), Technical language of Hardware, is a kind of turning point in digital circuit designing, which is being more and more complicated and integrated. Because of its excellency in expression ability of hardware, VHDL is not only used in designing Hardware but also in simulation for verification, and in exchange and conservation, composition of the data of designs, and in many other ways. Especially, It is very important that VHDL is a Technical language of Hardware standardized by IEEE, intenational body with an authority. The biggest problem in modern circuit designing can be pointed out in two way. One is a problem how to process the rapidly being complicated circuit complexity. The other is minimizing the period of designing and manufacturing to survive in a cutthroat competition. To promote the use of VHDL, more than a simple use of simulation by VHDL, it is requested to use VHDL in composing logical circuit with chip manufacturing. And, by developing the quality of designing technique, it can contribute for development in domestic industry related to ASIC designing. In this paper in designing SMPS(Switching mode power supply), programming PWM by VHDL, it can print static voltage by the variable load, connect computer to chip with byteblaster, and download in Max(EPM7064SLCS4 - 5)chip of ALTER. To achieve this, it is supposed to use VHDL in modeling, simulating, compositing logic and product of the FPGA chip. Despite its limit in size and operating speed caused by the specific property of FPGA chip, it can be said that this method should be introduced more aggressively because of its prompt realization after designing.

The conventional medical appraisal which was done in the process of medical lawsuit was requested from the court to the designated hospital and was delivered as a pattern of one question and one answer in each. However, the comprehensiveness of medical appraisal which was pursued, for example, in Korea Medical Dispute Mediation and Arbitration Agency, could be guaranteed in terms of in-depth medical analysis as well as the broader capacity of the causality estimation besides. The comprehensiveness of appraisal would also include how well organized hospital system of medical care is and how well correlated job system among medical staffs, when medical dispute was happened at the hospital. This comprehensiveness will exert a big contribution on making a demonstrative medical care to prevent from the medical dispute and it could achieve the national plan of building the patient safety net which is effective in restoring the worsened quality of contemporary medical service. Therefore, the comprehensiveness of medical appraisal has to be designed to go forward interdisciplinary fused speciality rather than one division of medicine, which is also aiming at the reliable and consistent appraisal with the supreme dignity from one window. In addition to that, the objective and concrete frame of comprehensive appraisal under the computed connection has to be deliberated to make itself possible in collaboration with positive participation of medical community. The comprehensiveness of medical appraisal would serve to expand not only the capacity of speciality but also the ability of influence on a restorative justice, so that it give effect to an increased number of mediation and arbitration rather than medical lawsuit as well as a decreased number of the social cost and social conflict.

The purpose of this study is to examine that high school students recognize mathematical situation when they are requested for changing identical mathematics situations into different situations. The results of the study are followings. First, percentage of correct answers to the questions of turning equal mathematical situation into function is higher than the one of turning equal mathematical situation into equation and inequality. As a result of individual interview for comprehensibility of the students on these relations, it is found that if degree goes up and there is different expressions of questionaries although mathematical situation is identical, it affects comprehensibility of the subjects. Second, we found that they cannot understand identical mathematics situations because they have trouble in drawing graph or applying to get the answer while many students understand a point of intersection on the graph as a correct answer. Third, As a result of individual interview for comprehensibility of the students on relation between equation, inequality and function, we found that students manage to get correct answer even without perfect comprehensibility on this relation.

The aim of the research is to estimate the effect of smoke and combustion gases on humane body indirectly through measuring the toxicity of those. For this purpose, the toxic index of smoke and combustion gases was investigated by smoke hazard test and analysis of smoke which were conducted by KS F 2271 and NES 713 method respectively. It i s proved by KS F 2271 method that PASCON trough is suitable to the testing standard of interior material and construction of building. In addition, it is identified by NES 713 method that combustion gases occurring in PASCON product were only carbon dioxide and carbon monoxide, and the smoke index of those was 0.944. This value means that the hazard effect of smoke gases on humane ! body can possibly happens when exposed to the smoke gases for more than 30 min. In aspect of the domestic situation that have not regulated the hazard estimation and the emissions of smoke when the flame retarding ability of the products have been requested, the toxic indexes of PASCON products are comparatively low.
