This study suggests methods of assessing scientific creativity and developing items, which can be achieved when both earth science knowledge and general creativity are applied at the same time. According to the results of this study, the cognitive ability gaps between creativity and scientific creativity were clearly defined by the terms' operational definition. Four factors in the Subcategory Of Scientific Creativity-fluency, flexibility, elaboration, and originality-were selected, and the possibility of developing items out of these factors was discovered. The operational definitions of the four factors were given and the criteria for assessment and scoring were set. The validity, reliability, discrimination, and difficulty, which were the conditions required for the assessment instruments, were verified through three field trials of inputting the assessment instruments for scientific creativity. The assessment instruments were composed of 8 items with 2items for each factor. The average item fitness index obtained was 0.99, Cronbach , the item inter-consistency was 0.79,the inter-rater reliability of each item was 0.78, the inter-rater reliability of each factor was 0.75, the item discrimination power was 0.19, and the item difficulty was 0.00. Because the results were within the permitted limit of the conditions required for assessment instruments, the assessment instruments developed for scientific creativity in this study can be said to be very favorable.

This paper describes implementation of IPv6-IPv4 transition toolbox named as 6TALK(IPv6 TrAansLator of Krv6) and some scenarios using 6TALK which enables IPv6 island to connect other IPv6 island or IPv4 island seamlessly. 6TALK implements some transition mechanisms suggested in NGTrans Working Group of IETF. Those mechanisms are composed of basic mechanism, tunneling, and applied mechanism such as DSTM. 6TALK provides functions which enable IPv6 network at the edge of existing network to communicate with IPv4 network by using these transition mechanisms. As major transition mechanisms in 6TALK we adopt NAT-PT/SIIT and DSTM/DSTM options and as implementation environment we use Linux Kernel 2.4.18 and Netfilter framework. Software modules implemented in Linux kernel was ported to hardware box using Motorola MPC 8260 processor. The transition mechanisms used in 6TALK are the ones predicted to be used in initial transition step to IPv6.

The Changes in management environment in SMEs such as rapid development of information communication technology, worldwide expansion of FTAs, enlargement of global outsourcing, etc have changed various aspects in industry-academy or industry-academy-government cooperation. It has been away from the cooperation focused on research and development and industrial training, and advanced to the cooperation focused on the business fields and practices where the executive ability and professionalism are required to commercialize major products of local SMEs. Compared with the existing model, the new model of industry-academy-government cooperation can provide effective and customized supports to local SMEs and expect better performance than ever before through the choice and focus. However, the existing support programs of government and related organizations are just top-down pattern to SMEs. In addition to the development of industrial technology, education and training for labor force and knowledge interchange between industry and university, the new cooperation model would also provide practical tasks such as enhancement of business competences and abilities to cultivate foreign markets. This study deals with Gyeongbuk PRIDE Products support project that is the new model of industry-academy-government cooperation and evaluates the effectiveness of this support project by empirically analyzing the survey results from the target SMEs.

It is important to asess the risk factors of parenting and provide early intervention for promotion of the maternal caretaking ability. The purpose of the study was to identify the maternal burden of caretaking, the supporting and the educational need for the caretaking activities of the mother of infant. Sixty three mothers of infants who visited the wellbaby clinic of S university hospital and one health center during the period of November 1st, to 30th in 1996 comprised the subjects of this study, Data were gathered through the instruments that were developed by researcher. Statistical analysis of this study was used ANOVA and Pearson correlation. The results were as follows : 1) The mean score of the maternal burden of caretaking was 22.06. The maternal burden of caretaking was significantly high in the mothers who had vaginal delivery compare with the mothers who had caeserean section and in the muthers who gave artificial feeding compare with the group of breast or mixed feeding. 2) The mean score of the support need for the caretaking activities was 30.69. The support need for the caretaking activities was significantly high in the mothers who had the second child, compare with the mothers who had first or third child. And the support need for the caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'immunization' and 'prevention of accident' on the support need for the caretaking activities were relatively high. 3) The mean score of the educational need of caretaking activities was 29.3. The educational need of caretaking activities was significantly high in the mother who had the second child compare with the mothers who had first or third child. And the educational need of caretaking activities was significantly high in the mothers who had caretaking help compare with the mothers who had no caretaking help. The specific subjects of 'mother-infant interaction', 'emergency care' and 'prevention of accident' on educational need of caretaking were relatively high. 4) The maternal burden of caretaking was not correlated with the support need or the educational need of caretaking activities. But the support need of caretaking activities was significantly correlated with the educational need of caretaking activities. 5) The support and educational need of caretaking activities were significantly high in the mothers who wanted home care for caretaking their infants. Through the study, it was found that there is considerable maternal burden of caretaking as well as the support and educational need on the caretaking activities in the mothers whose child is young. Therefore developing the systematic and effective program is needed to meet the mother's need. The results of this study will be useful resources to develop the program. On the other hand, it can be recommanded that home health care will be one of the approach to support the mothers caretaking activities.

The purpose of this paper is to analyze various categories such as the recognition, expectation and acceptability of CCTV use in educational facilities by doing a survey on how college students think about the CCTV installed in educational facilities. For this research, diverse existing surveys regarding CCTV were examined, and the appropriate elements of survey questions were extracted and developed. Based on this method, we intend to complete a survey study hereafter on the change in perception regarding CCTV inspection. We made four hypotheses before the survey and the results of the survey are as follows: First, the expectations for CCTV's ability to reduce crime were high. Second, the fears about being a victim of theft or violence crime were decreased. Third, there were a number of respondents who would weigh more on increased safety by installing a CCTV rather than be concerned that CCTV may lead to the violation of students' human rights. Fourth, there showed a difference in recognizing CCTV among three groups. Also, for the questions regarding the places where CCTV is installed, there were many negative opinions on its installation in the student convenient facilities. What we have achieved was not a simple survey which investigates the pros and cons about CCTV use, but a newly suggested way of survey, which enables us to test various hypotheses and figure out the changing perceptions on CCTV effectiveness in educational facilities with more efficiency.

The purpose of this study was to assess musically gifted students'needs in order to develop the gifted curriculum in music. The survey was carried out with 103 musically gifted students who are being educated in institutes for the gifted. The survey asked the needs about components of the gifted curriculum in music: the educational objectives, contents, teaching strategies, evaluation as well as educational environment influencing on the curriculum. As for the objectives, the result showed the highest needs was the ability to communicate with audience by expressing one's feeling. For the high school students, a large number items had significant differences between the necessary level and the current level. As for the contents, the highest needs were the class piano, second instrument, and the experience of the musical field. High school students needed the second instrument more than middle school students did. As for the teaching strategies, the highest needs were the autonomous choice by learners, the instruction pursuing learners' interests, and the field work. As for the evaluation, the highest needs were the peer evaluation and the evaluation on the collaborative performance or team work. As for the educational environment, the gifted in music strongly needed spaces to practice instruments. Additionally, high school students needed a space to perform like a concert hall. Thus the gifted curriculum in music must be thoroughly developed based on the result above.

The purpose of this study was to examine the validity of the Teacher's Scale for Gifted Preschool Children(TSGPC). Participation of this study were 357 preschool children and their parents and teachers from Seoul, Ulsan, Daegy, Gwangiu & Daejeon. Data were analyzed by exploratory factor analysis, Pearson's r, t-test and Cronbach's ${\alpha}$. Results are as follows. (1) exploratory factor analysis of TSGPC revealed that a 5-factor solution (academic ability, creativity, task commitment, artistic talent, and leadership) was the best fit. (2) Correlations between TSGPC and parental rating scale for young children's giftedness were significant. (3) Scores of TSGPC between gifted children and general children were significantly different (4) Cronbach's ${\alpha}$ ranged from .82 and .91 for subscale of TSGPC and .93 for the total scale. These results show that the Teacher's Scale for Gifted Preschool Children is quite reliable and valid measure.

Purpose: The purpose of this study was to compare the degree of tooth preparation abilities of students according to three self-assessment methods. Materials and Methods: forty-eight sophomores in Kyungpook National University College of Dentistry were divided into three experimental groups. Students performed tooth preparation of the left mandibular first molar for full gold crown. They performed self-assessment using the three methods (visual, digital, and putty index self-assessment group), and reperformed tooth preparation. An intraoral scanner was used to scan each tooth model (prepared tooth and unprepared tooth), and data were acquired in standard tessellation language (STL) file format. The STL files of prepared tooth and unprepared tooth were superimposed using the 3-dimensional analysis software (Geomagic control X). And the reduction amount was measured. In the statistical analysis, all values of reduction amount were analyzed with the Wilcoxon signed rank test and Kruskal-Wallis test (α = 0.05). Results: The three self-assessment methods showed statistically significant differences (P < 0.001). The putty index self-assessment group showed the highest reduction in error than the digital self-assessment method. Conclusion: Within limitations of this study, students showed significant differences in improvement of tooth preparation ability according to the three self-evaluation methods.

In recent years, space planning ability using 3D sketch software is required in the working field of interior design. However, vocational high school do not respond appropriately to changes in the industry, because the class of vocational high school consists of hands-on practical classes and 2D CAD based classes. There is a shortage of 3D sketch software-based instruction programs that can improve students' spatial planning skills. Therefore, this study is to develop instruction program using 3D sketch software for 'Planning for Residential Space' unit of NCS-based on interior design subject and to find out the effect on students' academic achievement by applying to vocational high school class. The 3d sketch software based instructional program developed in this study was developed through four stages of preparation, development, implementation and evaluation according to the PDIE model process. The experimental design model used nonequivalent group posttest-only design in this study. Experiments were conducted on vocational high school students in construction and 9 hours of interior design subjects were applied. After the experiments, students were tested for academic achievement in the cognitive, affective, and psychomotor areas. As a result, the instruction program using the 3d sketch program developed in this study was found to be more effective in improving students' academic achievement than existing manual instruction program in both cognitive, affective, and psychomotor areas.

Subjective cognitive-linguistic complaints in older adults contribute to the diagnostic and prognostic investigation of MCI or dementia. However, the utility of subjective test for predicting cognitive-linguistic decline is controversial. Few domestic studies have included the correlation between subjective and objective tests systematically. The current study analyzed 26 studies published since 2000, and the effect sizes of their correlation coefficients between two tests were computed. The results of qualitative analysis indicated that the number of subjects ranged from 26 to 657. Subjective tests included the self-report 75.4% and the informant-report 24.6%. In objective tests, memory comprised the largest proportion, followed by global cognition, and language, etc. As a result of meta-analysis, self-report test had the predictive value for dementia, and informant-report test contributed to discriminate among 3 groups. In the elderly group, self-report test was correlated with reasoning, and informant-report test with memory and language. In MCIs, self-report test predicted several abilities including language, and informant-report test signaled the future decline of domains like global cognition. Two types of subjective tests in dementia also represented memory, language, and global cognition accurately. This study provides evidence-based information to support relationships between subjective and objective tests for cognitive-linguistic ability in 3 groups.
