  • The contact resistivity of the black interlayer which has been introduced between BUS and ITO electrodes in a plasma display panel was evaluated using two kinds of specially designed test electrode patterns. Of the two, type 2 pattern was able to evaluate the contact resistivity more successfully, which was calculated as about $250{\Omega}$ in the suggested test pattern structure.

  • 본 연구에서는 공단에서 발생하는 악취물질을 냄새센서를 이용하여 상시 감시하는 것을 목적으로 한다. 현재 다종다양한 냄새를 측정하기 위한 악취평가 방법으로는 관능측정법이 이용되고 있다. 그러나 이 방법은 악취판정원의 냄새세기의 차이와 판정원(panel)의 생체리듬에 따른 차이로 인하여 냄새의 객관적인 평가에 무리가 따르며, 언제, 어디서 돌발적으로 발생하는 악취의 연속적인 감시에 문제점을 나타내고 있다. 더욱이 우리나라는 환경 악취에 대해 직접관능측정법에 의한 악취 측정이 실시 되고 있어서 객관적으로 악취평가를 하기가 매우 곤란하다.

  • A field-sequential color projection system can display color images using panel. However, it suffers from a characteristic trichromatic separation known as "color breakup". The viewing of images exhibiting color breakup may cause visual fatigue and mental stress. In this study, the authors examine, from the standpoint of human factors, the objective and subjective symptoms that can result from the viewing of images with color breakup.

  • To meet standards for high quality of care and satisfied customers, an evaluation tool about nursing care is necessary. And, We need to evaluate our practice continuously for the improvement in quality and outcomes. This study was intended to develop an evaluation tool about nursing care in NSICU, and was progressed of 3 steps; development, content validity verification and reliability verification. Data were obtained and analysed from Feb. To April, 2000. Development process of the study was as follows A preliminary list was made item by item on the basis of clinical Experience, literature review and patients' record review. Then the standards, criteria and indicators of preliminary evaluation tool were set by 5 clinical nursing panel, and their content validity was reviewed by 27 ICU nurses. Finally, an evaluation tool was developed and verified the reliability at c-university hospital located in Kwang-Ju. The results of this was as follows 1) The evaluation tool of this study developed 8 standards, 39 criterias and 106 indicators. The standards were divided into two dimensions. One was process dimension which contained 4 standards(26 criteria), The other was outcome dimension which contained 4 standards(13 criteria). 2) the Average content validity of the tool was 3.39 at standards, 3.55 at criteria and 3.51 at indicators. 3) Interrater reliability of the tool is r=.7993(p<.001) & internal consistency reliability ${\alpha}$ is .6031 4) Scores of NSICU Patients who participated in this study were 57 at total mean score, 58 at process mean score and 56 at outcome mean score The evaluation tool developed in this study seems to be useful in evaluation nursing practice appropriately for the improvement of nursing care in NSICU. I hope that this evaluation tool can be used effectively in NSICU as an intervention for the improvement of quality control.

  • Affective aspects of design attributes such as color, Pattern, and texture are important to the overall impression and the success of interior products. Among all the interior materials, wallpapers and flooring materials take up largest construction area and they are main components in creating affective impression for customers. This study aims to investigate the relationship between luxuriousness and related affective variables and design elements of wallpapers and flooring materials. The approach consists of 3 steps: (1) selecting related affective features and product design attributes through a literature survey, opinion of expert panel, and focus group interview, (2) conducting evaluation experiments, and (3) developing Kansei models using multivariate statistical analysis and analyzing critical attributes. Evaluation experiment was conducted using a questionnaire made up of 7-point scale and 100-point scale and 30 housewives and 20 interior designers participated in the evaluation experiment. The result of evaluation was analyzed through principal component regression and quantification I analysis. As a result of analyzing the survey data, the relationship between luxuriousness and related affective features and product design attributes was identified, moreover a optimal combination of the design component was identified. Consequently, it is expected that the results of the study would be a basis of the concept of emotion-based design by giving insights about how customers perceive the luxuriousness and suggesting the optimal combination, and providing specific quantitative design guidelines.

  • The present status of the thennomechanica1 evaluation of functionally gradient materials(FGMs) for space plane application was reviewed, in which research activities and the cooperation of the national project team organized to study FGM science were demonstrated. The project team was divided into three working groups; de singing, processing and evaluation, each of which had their own tasks in the project cooperation. The testings details of the various thennomechanical tests for the FGM samples fabricated by the processing groups were described, along with their corresponding heating conditions of the real environments in the space plane application. For small-sized samples, laser beam heating test and burner heating test were well applied to study the heat shielding and heat resisting properties. Arc-heated wind tunnel test and high temperature!high velocity gas flow test were used for large-sized panel assemblies having cooling structures. The criteria for the evaluation of the heat shielding and heat resisting properties of the FGMs, as well as a crack activation mechanism in their differential temperature heating, were proposed on the basis of the observation in the burner heating test.

  • This investigation was undertaken for me purpose of studying me sensory and textural properties of Julpyun (Korean traditional rice cake) made by various soaking time (1, 4, 6, 8, and 12 hours) of rice during storage at room temperature. The storage periods were 2, 4, 6, and 10 hours. Sensory evaluation was done by a panel of 12 judges majoring in food and nutrition. The luation was repeated 3 times. Objective evaluation was done by rheometer and color difference meter. As a result of me sensory evaluation for Julpyun made by various soaking time and storage periods, mere were significant differences (p<0.001) in most of characteristics between soaking time and storage periods. Julpyun made by soaking time for 12 hours showed the most favorite tendency during storage periods. The result of textural properties measured by rheometer showed similar trend to those of sensory evaluation. By me color difference meter, L (lightness) value were increased by increasing the soaking time. There were significant differences (p<0.001) between me samples.
