This study investigated whether applying the Project-Based Learning in LIS education affects students' self-efficacy for group work in a positive direction and if the authenticity of the project has any relationship with their self-efficacy for group work. 26 students were surveyed before and after they took the "Evaluating Digital Library Systems" course with the same set of questions asking about their perceptions on the individuals' capabilities to successfully perform group tasks and their perceptions about the project's authenticity. The paired sample t-test showed statistically significant differences between the results of the pre- and post-test, in terms of their capabilities as a leader as well as exchanging, evaluating, and integrating ideas when performing group activities. In addition, the authenticity of the project's task shows some correlation with subfactors of students' self-efficacy for group work.

The purpose of this study was to develop voluntary learning (talent donation) program as a liberal art lecture for students in G university to cultivate consideration towards others and community life. The title of the liberal education course that was developed was decided as "Beauty Talent Donation". The course objectives were to develop consideration for others and sociality required for community life as well as foster awareness of sharing and develop creative leaders equipped with outstanding characters through cosmetology voluntary service associated education. The final development of education contents were completed over 3 stages including preparation, development, and supplemented development and the major components consist of understanding talent donation, beauty theories, and beauty skills. For the assessment of the learners, absolute evaluation was applied so that personal goals can be achieved through the course instead of evaluating learners' learning capabilities with relative evaluation. Accordingly, a pass or fail system was designed. The beneficiary institution of talent donation was selected based on the following conditions. It is located within a short distance from the educational institution, walking distance for the learners, easy to recruit subjects to receive the support, and accurately understands the purpose of the lecture and willing to cooperate.

Auditory and language train for the hearing-impaired is an essential course improving conversational capability with non-deaf and accompanying the financial burden and the physical fatigue of parents or a teacher. To reduce these problems, web-based training contents have been developed. But these contents have been developed without consideration of individual difference such as various levels of residual hearing and the learning capability of hearing-impaired. Therefore, it is important that appropriate training progress for each hearing-impaired should be designed by evaluating and analyzing the personal status, residual hearing, learning capability and training achievement. This paper suggests auditory and language training service model for the hearing-impaired, which is planning and managing an auditory and learning training based on personal evaluation. In addition, this paper suggests a design method for a serious game content planing based on this service model.

Purpose: The main purpose of this study was to compare the effects of OSCE method and the traditional evaluation method on nursing skills performance of students enrolled in fundamentals of nursing courses. Method: The study was designed as a quasi-experimental, nonequivalent control group post test design with two classes of sophomore students attending fundamentals of nursing courses at one baccaleureate nursing school located in a metropolitan Seoul area. The control group was evaluated using a traditional method and the experimental group was evaluated using the OSCE method. Data were collected from June, 2001 to June, 2002. There were 35 students in the OSCE method group and 39 students in the control group. Data analysis was done using SPSS WIN 9.0. Result: The results showed that the students in the OSCE method group did significantly better in clinical nursing skills performance than the students in the traditional method group. And the OSCE method group showed significantly higher satisfaction score in the evaluation method than the control group. Conclusion: The OSCE method is an effective tool for evaluating clinical nursing skills performance in student nurses. It is necessary to explore more efficient ways to develop OSCE cases in wider areas of nursing education. It is also recommended to replicate similar studies in nursing education.

During the course of a study to develop a spraying program at 15-day spray intervals, two important findings were identified allowing for further reduction of spray frequency by increasing the spray interval. In evaluating the contribution of fungicides from a 15-day spray interval program, control of white rot, which is of prime importance in Korea, was not affected, in spite of the extended spray interval caused by omitting the fungicides during the season. In another experiment assessing the duration of the protective activities of several key fungicides used in the 15-day spray interval program, infection control was maintained for almost 30 days for some fungicide. Based on these two findings, a basic spraying program with a 25-day spray interval was developed. This program was modified for four successive years to improve the control efficacy against bitter rot and Marssonina blotch, which sometimes causes as much damage as white rot.

For the purpose of evaluating the appropriateness of AP-PCR as a facile, rapid and reproducible method for genotyping Streptococcus mutans, and selecting the discriminant primer for it, a DNA fingerprinting was performed on the microorganisms isolated from caries-free children and children with rampant caries, respectively. In the course of selecting appropriate primer for S. mutans genotyping, we chose S2 primer from 6 different primers which shows highest resolution on the agarose gel as well. Nineteen kinds of fingerprint patterns were observed in caries-free children and children with rampant caries which were produced by combination of 7 different fragments. Interestingly, the number of types observed in caries-free children was greater than that in children with rampant caries. And we observed Type 2 was predominant in children with rampant caries (about 80%) and relatively even distribution of each types in caries-free children. Furthermore, it was appeared that the major types in normal control were not or rarely found in children with rampant caries. In conclusion, we could establish simple, rapid and highly reproducible AP-PCR method for genotyping S. mutans. We also found differences in distribution of S. mutans between normal and patient, which suggested that cariogenicity is also dependent on qualitative aspects which is caused by the difference in genotypes of S. mutans in oral cavity.

The most significant factor in pathogenesis of vascular headaches like migraine and cluster headache is dynamic changes of diameters of the cerebral arteries. TCD is a valuable noninvasive tool to assess the cerebral hemodynamic status by measuring the flow velocities of the intracranial cerebral arteries around the circle of Willis. TCD can evaluate flow velocities and vasoreactivity of the patients with a vascular headache during the ictal phase as well as during intericatal phase. Distribution of the changes recorded differ between types of headaches and also between the major ictal symptoms. The changes suggest the presence of prolonged vasospasm interictally and more marked relaxation of the cerebral arteries. TCD can be used to monitor the long-term clinical course of patients with vascular headache by correlation the symptomatic improvement and TCD data before and after long-term pharmacological prophylactic treatments. During the ictal phases large intervention. The results may be used in selecting and evaluating the agents for abortive therapy for acute attacks. In conclusion TCD can quantitatively evaluate vascular headaches when making diagnosis and classification and can provide guidelines to choose more individualized therapeutic options for both acute and long-term treatment.

It is of great importance for any vessel under way, especially in rough sea, to be maneuvered safely with proper seakeeping performance. In this paper, the author aims to develope a navigational safety evaluation system in rough sea by analyzing ship's with the theory of wave spectrum using random process analysis and the theory of evaluating the seakeeping performance. The scope and the method of this study are as follows ; (1) Modelized typhoon mathematically to represent the sea condition in rough sea. (2) Estimated sea conditions by getting wave spectrum, supposing that the wave by typhoon is fully developed short crest irregular wave. (3) Defined evaluation factor of vessel's seakeeping performance and obtained response amplitude operators thereby. (4) Obtained the response spectrum of factors on seakeeping performance. (5) Defined and obtained evaluation index, dangerousness, relative and maximum dangerousness of factors on seakeeping performance. (6) Analyzed the calculated dangerousness of evaluation index and picked the vertical acceleration out of 7 factors as the presentative factor on seakeeping performance. (7) Carrid out the judgement of danger by obtaining dangerousness value according to steaming hour, course alteration and speed change. By synthesizing the above items, the authors suggests a computer model of navigational safety evaluation system and examined the validity of the model by computer simulation.
