The purpose of this study is to analyze the perception on science and scientists of the teachers who are engaged in the special education for the scientifically gifted, science-gifted students and their parents. For this study, 34 teachers, 222 students and 107 parents answered the questionnaire of the perception on science and Draw-A-Science-Test (DAST). The result showed that the three groups generally had a sound recognition but the score of recognition about a 'nature of science' was lower than other domains. The science-gifted students had less cognition about 'science and society' than their teachers and parents, but they had more positive perception about 'science learning' than their parents significantly. All of the three groups had the stereotyped image of scientist. About the internal images of scientists, three groups had a similar perception, and they showed higher scores in the cognitive aspect than emotional or ethical aspects. And the science-gifted students showed the significantly higher scores than their teachers and parents in diligence, imaginative power, concern about other people, respect for other's opinion, humor, artistic sense, respect for human, desire for peace. Three groups turned out to be influenced by movie, science journal, and biography as a source of scientist's image, but their contribution was different among groups.

Information service organizations that provide science and technology information with a relatively short information life cycle for free or paid are in need of reflecting rapidly changing user needs and behaviors and grafting the latest technologies. The purpose of this study is to derive improvements for each system by comparing and analyzing general recognition of science and technology information users' domestic and foreign science and technology information sites and importance by science and technology information attributes. A total of 816 users of science and technology information participated in the online survey, and the collected data were analyzed by quantitative methods including IPA (Importance Performance Analysis) technique. The importance was evaluated by the impact value calculated through regression analysis. As a result of data analysis, the general recognition of users on science and technology information sites was relatively high in national science and technology information services, and Google Scholar and Science Direct were also high. Google Scholar was found to have more strength than improvement. A better understanding of the user's preferred system is a good driving force for improving the lack of existing systems. It is necessary to improve the information retrieval of the science and technology information service system, that is, to improve the search speed and functions, and also to improve the user interface with improved convenience and usability.

Objectives: Yearly, annual report of cancer patients in Korea is released by National Cancer Center. But, this report is focused in all of the patients in nation. So, there is needed to modify and analyze this report to be used properly for local resident. In Ulleung island, local county and Ulleung medical center don't have cancer occurrence data of local resident until now. The aim of this analysis is to know characteristics and data of cancer patients occurrence in Ulleung island for 10 years. Methods: We are offered data of cancer patients occurrence in Ulleung island for 10 years from National Cancer Center. This data was composed of sex, address (only town level), diagnosed date, diagnosis. So, we analyze this data and compare to Korea data for same duration. Results: There were 268 patients for 10 years (1993-2002). Man were 175 about 65% and women were 93 about 35%. There were 163 in Ulleungeup about 60%, 39 in Seomyun about 14.5% and 48 in Bukmyun about 18%. There were 19 patients in unknown residence. After 1998, above 30 patients were occurred, but before 1998, below 27 patients were occurred. Diagnosed date was concentrated in June, 33 patients were occurred about 12%, but least occurred month was December. Most occurred age were from 60 to 69, there were 80 patients about 30%. Most occurred cancer was gastric cancer, there were 54 patients about 20%. Hepatic cancer was second and third was lung cancer. In man, most occurred cancers were gastric cancer and hepatic cancer, both was 38 patients. In woman, gastric cancer and uterine cervix cancer were occurred mostly. After 2001, in Korea most occurred female cancer was breast, but in Ulleung island, most occurred cancer was stomach. Conclusions: Researcher should demand and analyze cancer data from National Cancer Center that cancer management project in local county and public health education of cancer could focus on local resident because annually released cancer data from National Cancer Center focus on a nation. In Ulleung island, cancer incidence was more than incidence in Korea and breast cancer was occurred less than in Korea. So, more study should be needed to confirm why more cancer were occurred than Korea and breast cancer was less occurred.

The selection of a third-party logistics (3PL) provider is a critical process for shippers who want to receive competitive logistics service. However, studies analyzing the factors that influence the selection of 3PL provider from the viewpoint of shippers are insufficient. The present study aims to derive factors to be considered when selecting a 3PL provider by domestic shippers and to present the weights of each factor. The analysis results showed that among the major factors, the "operation factor" showed the highest importance, followed by "strategic factor", and "communication factor". The results of compound weights showed that "cost reduction" is the most important factor, followed by the "expertise of the provider", "inventory management ability", and "human resources management". The present study proposed the core factors that should be considered when selecting a 3PL provider from the shipper's viewpoint. This study also has an industrial implication from the viewpoint of 3PL providers because it provides the basic data for enhancing the shipper's satisfaction by reinforcing the factors that are considered important in by shippers. In future research, it is necessary to classify shippers by industry and analyze the differences in the factors that arise in selecting 3PL companies for each industry.

The user's composition of socia-economic characteristics in Bukhan Mountain National Park showed that male. twenties and students were 65.4 percent. 62.7 percent and 37.4 percent respectively by sex, age and occupation. In visiting purpose, the nature-oriented motive was 67.1 percent of the total. hut the picnic patterns as of neighbourhood park and the recreation patterns as of recreation ground were appeared simultaneously. In preferable place of visitors. the well-known mountain hut, camp sites and summits were prefered. The level of scenic satisfaction was 7.8 and comparatively high on considering the maximum level of 10.0. The level of total satisfaction. however, was no more than 6.3 owing to lack of accomodation facilities along trails, 63.4 percent of visitors were opposed to construction cable-car and visitors were anxious seriously about the nature deterioration. In Jeongnung valley, the number of users was the lagest, so that the maximum number of passangers a day attained to 20.000. The peak seasons of visiting were Spring and Fall, and the peak hours during a day was 10-11 hours A.M. and 3-5 hours P.M. Therefore partitioned spatial management in consideration of hiking pattern of nature park. picnic pattern as of neighbourhood park and recreation pattern as of recreation ground shall be necessary to solve the conflicts among functions.

Domestic sign industry has seen a rapid growth in recent years, however, the level of quality is not so high. The main reason for this is due to the lack of well educated specialists. Thus, in this investigation, we will develop sign design experience software for the experienced employees in sign industry. Especially, focusing on the indoor letter information, we will develop the software that can provide the graphic effect associated with letter information. First, current situation and preliminary study in sign system used in public information were conducted, then design elements were analyzed from this. Then, experiments were performed on teh analyzed elements, and evaluation methods for the sign design were determined. Experiments including typography, color, layout, line alignment, letter space, and line space were conducted to analyze the visual perception. From these experiments, effective elements can be extracted and used as a elements for sign design software. As a next step, we will propose the development of experience software in sign design that can help to determine the sign elements. Thus, our investigation will provide sign design experience software that can be used by any inexperienced individuals, and be a great help for the more effective sign planning.

In this study, we applied the Bayesian Networks for the case of the trip generation models using the Seoul metropolitan area's house trip survey Data. The household income was used for the independent variable for the explanation of household size and the number of cars in a household, and the relationships between the trip generation and the households' social characteristics were identified by the Bayesian Networks. Furthermore, trip generation's characteristics such as the household income, household size and the number of cars in a household were also used for explanatory variables and the trip generation model was developed. It was found that the Bayesian Networks were useful tool to overcome the problems which were in the traditional trip generation models. In particular the various transport policies could be evaluated in the very short time by the established relationships. It is expected that the Bayesian Networks will be utilized as the important tools for the analysis of trip patterns.

Absorption pattern and sensitivity of radishes to boron were compared with different boron treatment: soil application, foliar spray and no boron application. Six radish cultivars were planted on April 7 and harvested on June 23. Borax 1.5 Kg per 10 a was applied to soil before seeding and the 150 litters of 0.5 ppm solution with bolic acid was sprayed on leaves 3 times during the growing period. Boron content in plant was markedly increased by the soil application but no significant difference in boron contents in plants was observed between foliar spray and no application, presumably because of the insufficient dose of foliar spray. The darkening rot in root, a boron deficiency, was negligible in radishes grown in soil application plots whereas a relatively higher percentage of boron deficient plant was found from foliar spray or no application plots. The appearance of root darkening rot occurred at the rapid root enlargement stage, apparently from 55 days to 65 days after seeding. The boron contents in plants of soil application plots slightly increased at this stage while those of no boron application and foliar spray decreased. This obviously verified that boron deficiency should cause root rots showing highly significant relationship.

Reinforced concrete beams of existing structure often encounter insufficient shear problems for various reasons. Application of steel plates is one of widely used methods for shear strengthening of reinforced concrete beams that are insufficient of shear capacity. This study presents test results on strengthening shear deficient RC beams by external bonding of vertical and diagonal slit type steel plates with anchor bolt. Test parameters are width, interval, angle and length of slits with anchor bolt. The purpose was to evaluate the failure modes and shear capacities for RC beams strengthened by various slit type steel plates with anchor bolt. The results showed that the slit type steel plate specimens strengthened by adhesive bonding and bolting failed in shear fracture modes at maximum load. Flexural crack first occurred on the tension face of beam and then inclined cracks occurred on the shear span. Finally, slit type steel plates strengthened by adhesive bonding and fastening bolts managed to delay abrupt debonding and didn't detach fully from main body of RC beam.
