Graduates from engineering colleges are demanded to have been acquired some abilities and qualities during their undergraduate years through the standard of the so-called "programmed learning results and evaluation" This paper aims at analyzing the learning results evaluation tool for graduates from the architectural engineering department through the examples of the colleges with engineering accreditation in Korea, and suggesting a more appropriate programmed learning result evaluation tool. The basic theories on programmed learning results were studied, and then the previous study examples were researched. The study objects were limited to the fourteen colleges which offered the examples of the learning results evaluation tools of the colleges with engineering accreditation in Korea. Types and the present situation of those evaluation tools were analyzed. In addition, the proposals for the evaluation tool of programmed learning results and the performance standard were suggested for those with an engineering accreditation, based on the case study of the performance standards of each college with an engineering accreditation. The study results showed that much more national research needs to be conducted to clarify the standards of selecting an evaluation tool and a performance standard appropriate for the level of each college so that it can make a proper proposal.

5-Arylamino-6-chloro-4.7-dioxoindazoles (DZs) were newly synthesized for the evaluation of antifungal activities. The compounds DZs were prepared by regioselective nucleophilic substitution of 5.6-dichloro-4.7-dioxoindazoles with appropriate arylamines in high yield. DZs were tested for their growth inhibitory activities against Candida species and Aspergillus niger. The MIC values were determined by the two-fold dilution method. In general. DZs showed in vitro antifungal activities. Among the tested compounds, DZ1, 3, 6, 7 and 12 showed potent antifungal activities against Candida species and Aspergillus niger. DZ7 was the most effective in preventing the growth of Candida species.

Brominated flame retardants (BFRs) are present in many consumer products ranging from fabrics to plastics and electronics. Wide use of flame retardants can pose an environmental hazard, which makes it important to determine the mechanism of their toxicity. In the present study, dose-dependent toxicity of tetrabromobisphenol A (TBBPA), a flame retardant, was examined in male prepubertal rats (postnatal day 18) treated orally with TBBPA at 0, 125, 250 or 500 mg/kg for 30 days. There were no differences in body weight gain between the control and TBBPA-treated groups. However, absolute and relative liver weights were significantly increased in high dose of TBBPA-treated groups. TBBPA treatment led to significant induction of CYP2B1 and constitutive androstane receptor (CAR) expression in the liver. In addition, serum thyroxin (T4) concentration was significantly reduced in the TBBPA treated group. These results indicate that repeated exposure to TBBPA induces drug-metabolising enzymes in rats through the CAR signaling pathway. In particular, TBBPA efficiently produced reactive oxygen species (ROS) through CYP2B1 induction in rats. We measured 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker of DNA oxidative damage, in the kidney, liver and testes of rats following TBBPA treatment. As expected, TBBPA strongly induced the production of 8-OHdG in the testis and kidney. These observations suggest that TBBPA-induced target organ toxicity may be due to ROS produced by metabolism of TBBPA in Sprague-Dawley rats.

Objectives: This study was to compare the self-evaluated outcomes of communication competency in dental hygiene process of care in the students of a dental hygiene department with the teaching evaluation, and to confirm the difference of communication competency by the evaluator. Methods: This study attempted to confirm the value and usefulness of self-evaluation and teaching evaluation on the communication competency. The subjects of this study were 43 junior students who took a course of dental medical communication at the dental hygiene department of a university located in 'A' city, and the self-evaluation and teaching evaluation were conducted using the evaluation paper which was modified from the communication evaluation tool in the previous studies. The collected data were subjected to the correspondence sample t-test to compare the difference between the communication competency self-evaluation before and after the education, and after communication education, while an independent sample T-test was conducted to compare the differences between the evaluators. Results: The student's self-evaluations before and after the education showed the statistically significant difference, moreover, the post-education competency scores were improved mostly in all the items more than the pre-education competency scores. The score of self-evaluation was higher than that of the teaching evaluation in all items except one question in the case of history-information collection stage. Conclusions: It is confirmed that there is an effect to allow the students to improve their communication competency in the dental health communication education in the dental hygiene department. To evaluate the student's communication competency, the mutual complement of self-evaluation and teaching evaluation should be confirmed in parallel each other.

This study was carried out to investigate several effects of smoking and alcohol-drinking on the health of rural residents. The subjects were 710 people (325 males and 385 females) in rural area, Young-Duk Gun, Kyungbuk, Korea. The data were collected by medical students trained for this study during 4 days from 31 August, 1996. Questionnaire contents were general social characteristics, period of the agriculture, smoking history, alcohol-drinking history, some psychosomatic symptoms and self-evaluation for health. The results obtained are as follows : 1. Positive rates of the some psychosomatic symptoms and self-evaluation for health were higher in female than in male and were significantly increased as the as increased(p<0.05). 2. Smoking rate was 56.9% in male and 4.9% in female. In positive rates of the some psychosomatic symptoms and self-evaluation for health in male, 'insomnia' was only significantly lower in ex-smoker than in smoker and non-smoker(p<0.05). Other items were significantly not different. 3. Prevalence rate of alcohol drinker was 54.8% in male and 17.1% in female and the alcoholism was 8.3% in male and 0.8% in female. Positive rate of the some psychosomatic symptoms and self-evaluation for health in male were significantly not different. 4. The scores of self-evaluation for health was divided into two groups under two point and over three. And the analysis of multiple logistic regression shows that there were significant relationship with age and sex. This study suggests that some psychosomatic symptoms and self-evaluation for health were significant relationship with age and sex but not smoking and alcohol-drinking.

An accurate evaluation of educational process is a promise for the progress of education, because evaluation provides a meticulous idea of what has actually been achieved as a result of education. However, for all its significance in the educational fields, there are not many discussions about evaluation in South Korea. We believe that in order to overcome this discrepancy, diverse evaluation theories along with a discussion about the merits or demerits or each theory should be introduced in South Korea. We propose that Eisner's educational evaluation model may suggest alternative ways of perceiving evaluation. Eisner's educational evaluation model, named educational connoisseurship and criticism, emerged as an approach to educational evaluation from the methods used in art and literary criticism.

In this paper, we propose the IPTV QoE evaluation method reflecting service user's preference. This method can evaluate the IPTV service QoE using the fuzzy integral because it usefully employs a subjective decision for QoE(Quality of Experience) evaluation. IPTV subscribers can prepare a criterion to select an IPTV provider who provides high qualityQoE.

Computer-generated holograms (CGH) are the core devices to solve the problem of freeform surface measurement. In view of the overlay error introduced in the manufacturing process of CGH, this paper proposes an evaluation model for analyzing the overlay error of CGH. The detection method of extracting CGH profile information by an ultra-depth of field micro-measurement system is presented. Furthermore, based on the detection method and technical scheme, the effect of overlay error on the wavefront accuracy of CGH can be evaluated.

The objective of this study was to compare the wood anatomical characteristics of local tree species in Moluccas, Indonesia i.e., Moluccan ironwood (Intsia bijuga), linggua (Pterocarpus indicus), red meranti (Shorea parvifolia), and gofasa (Vitex cofassus). Qualitative evaluation was conducted by observing the anatomical structure in cross, radial, and tangential sections of each sample. For the quantitative evaluation, the dimensions of vessels, rays, and fibers were measured. Qualitative evaluation showed that crystals were observed in Moluccan ironwood, linggua, and gofasa, while resin canals were only observed in red meranti. Tyloses were frequently observed in gofasa but infrequently observed in linggua and red meranti. Quantitative evaluation showed that Moluccan ironwood with the higher density had thicker fiber wall, higher quantity of ray number, and wider rays than the other species. Red meranti had higher values of ray height and fiber length than the other three species. The results also revealed that linggua showed the highest values of relative crystallinity and crystallite width. Red meranti and gofasa showed similar values of relative crystallinity and crystallite width, while Moluccan ironwood showed the lowest values. The basic qualitative and quantitative anatomical characteristics discussed could provide useful information for further utilizations of such wood species.
