  • 소프트웨어의 측정값에 근거하여 소프트웨어 품질에 관한 의사결정을 할 때, 동치관계의 요구조건인 추이적(transitive) 특성이 항상 만족되는 것은 아니다. 순환수(cyclomatic number)가 거의 비슷한 프로그램에서, 하나의 \"구조적인\" 프로그램 범주에 속하고 또 다른 하나는 \"비구조적인\" 프로그램 범주에 속한다고 명확히 분류할 수 있는가하는 점이다. 따라서, 본 연구에서는 동치관계보다는 허용적 관계를 만족하는 허용적 러프집합에 근거한 소프트웨어 분류기준을 제시하고자 한다. 분류기준을 생성하기 위한 실험 데이터 집합을 수집하고, 집합 내의 각 원소에 관한 허용적 클래스들을 생성한 후, 각 허용적 클래스들의 중심값을 클러스터링하여 분류기준을 생성한다. 생성된 분류기준을 또 다른 실험 집합에 적용하여 비교 분석한 결과 생성된 분류기준이 타당함을 보여준다.생성된 분류기준이 타당함을 보여준다.

  • This study addresses the evaluation on the satisfaction of school illumination quality by applying SERVPERF model after extracting factors affecting school illumination quality. Three types of illumination systems (fluorescence light, general LED light and high color rendition LED light) were tested by students who have used each illumination system. Three factors such as effectiveness, esthetic sense and function were developed for evaluation. Satisfaction evaluation was performed based on applied SERVPERF model by comparing perceived levels. The differences of perceived levels of satisfaction on the illumination systems were analyzed by ANOVA. The results said respondents satisfy only the high color rendition LED light regardless of three factors. Especially, students who experienced high color rendition LED light have strong intention to recommend that illumination system to other schools. They also express their desire to use that system at home. Interestingly, there is not much satisfaction difference between fluorescence light and general LED light.

  • For the investigation of the effects of G. lucidum on prevention and attention of hypercholeste-rolemia and atherosclerosis dietary hypercholesterolemic rats were fed with 2.0g% G. lucidum extracts for 4 weeks. And then concentrations of total cholesterol triglyceride phospholipid in serum and liver and those of HDL-cholesterol lipid peroxide glucose in serum were analyzed. Concentration of total cholesterol in serum was the lowest in the control group(basal diet+ wa-ter) and HDL-cholesterol in serum were significantly higher in groups of control 2(hyperchole-sterolemic ratslongrightarrowbasal+water) and 4(hypercholesterolemic ratslongrightarrowbasal+G.l. extract) The concentration of triglyceride in serum were signficantly lower in groups 4 and 5(hypercholeste-rolemic ratslongrightarrowcholesterol+G. l. extract) than in the control group. Phospholipid content in serum were not significantly different among all groups. Ttal cholesterol in liver was significa-ntly higher in hypercholesterolemic rats than in the control group and triglyceride concentration were signficantly higher in groups of 3(hypercholesterolemic ratslongrightarrowcholesterol+water) and 5 than others. Phospholipid in liver was significantly higher in group 3 than in the control group but groups of 4 and 5 were lower. As for lipid peroxide in serum was the lowest in group 4 and glucose concentration was lowest in group 5 than in other groups.

  • The purpose of this study was to examine the effects of Tai-Chi for patients with chronic arthritis. This study was performed from 15th Sep. to 7th Nov. 2003, 57 arthritis patients were participated in the Tai-Chi program. Outcome measures were pain, fatigue, flexibility and balance. Data were analysed by $X^{2}-test$ and t-test. There were statistically significant in fatigue, and knee flexibility, but no significant differences were found in pain and balance. In conclusion, Tai-Chi program was proved to be an effective nursing intervention to increase the fatigue and flexibility. And the 12 forms of Tai-Chi program has been found safely applicable to the patients with chronic arthritis for 8 weeks.

  • This study was to investigate fat content and fatty acid composition of 19 various fast-foods. Fat content per serving in double cheese burger was 38.8g, shrimpburger 27.5g, gogi-mandoo 26.3g, pizza 25.8g and chicken nuggets 18.8g, respectively, Fatty acid contained in fast-foods mostly were oleic acid, palmitic acid, linoleic acid and stearic acid. The ratio of P/S in yubuLchobab was 3.l/l, ccochinoodle 2.3/l, pork cutlet 2.3/l, bibimbab 1.511 and shrimpburger 1.3/l when all the other tested fast-foods'P/S were less than 1. The ratio of P/M/S in ham cheese sandwich was 1/1/1, shrimpburger 1.3/1.5/l, bibimbab 1.s/l.5/l, which are similar to recommended 1∼1.5/1∼1.5/l. The ratio of 6/3 fatty acids was found to be kimbab(34.0/l), chicken nuggets(25.3/l), ccochi noodle(20.0/l), yubu-chobab (16.5/l), fried chicken(16.3/l), chickenburger(12.6/l) and hot dog(10.2/1), which were higher than 10/1. Also pizza(3.511), spaghetti(3.7/l) were lower than 4/1. The rest of the fast-foods were within the range of 4/1∼10/1.

  • Purpose: The purpose of this study was to develop the tool that can be used for measuring and appraising the performance of Oncology Advanced Practice Nurse(APN). Method: On the basis of some articles about roles of oncology APN, the researcher made a temporary tool and verified both content validity and face validity. Also the reliability and construct validity were verified. Result: The reliability of this tool was measured by internal consistency. Cronbachs' ${\alpha}$ was .92. The method of verification of construct validity was used known group technique because of small numbers of Oncology APN. Conclusions: This performance appraisal tool of Oncology APN was verified by both the reliability and construct validity. In future, this tool will be able to be used for appraisal and verifying of nursing care of Oncology APN.

  • A new non-contact method of the frost thickness measurement has been developed. The method is based on the digital image processing technique to identify the reflection edge of the image captured by a CCD camera under laser sheet light illumination. To insure the accuracy of frost layer thickness, an in-situ calibration procedure is carried out with a calibration target with 0.5mm holes. Using the mapping function obtained by the calibration procedure, the contour of frost surface can be estimated with sub-pixel resolutions. The developed method is applied to study the effect of cooling plate temperature on the frost thickness in a small low speed wind tunnel.

  • 본 논문에서는 기존의 PSA기법인 사건수목/고장수목의 단점을 보완한 동적 신뢰성 평가도구인 DYLAM방법론을 이용해서 참조원전$^{[1]}$ 소외전원 상실사고시 노심노출 사고발생 빈도를 평가하였다. 부분충수 운전시 발생될 수 있는 노심의 노출을 예방하기 위한 운전원의 여러가지 조치들의 오류가능성애 대한 민감도 계산을 수행하였다. 민감도 분석의 결과 일차 충전 및 유출운전 (Feed and B띤) 인적오류가 노심노출 사고발생 빈도에 가장 큰 영향을 미치는 것으로 분석되었으며 정지생각계통 기능회복을 위한 조치는 상대적으로 적은 영향을 끼치는 것으로 나타났다. 또한 정지/저출력으로 운전하는 부분충수 운전시 전 출력에 비하여 노심노출올 무시할 수 없음도 보여주었다.
