The reason why creativity becomes the important subject in 21th century is that it does an important role which solves many problems surrounding our whole life in this internationalization, globalization, knowledge-information age. But scholars who formerly researched the creativity-field explain the necessity of creativity with the internal and fundamental reasons. That is, scholars say that creative activities produce originative products and originality itself. And it is the root of which will be able to discover meaning of life and it -creativity - is successive activities that is demanded when individual life want to obtain important value by expressing one's inner world to the outside using creative resource. Recently, with the trends of present age and the educational needs, research about creativity is actively carried out and it draws out the results that creativity can be developed and enhanced through education and training. So, now many researches have focused on how to develop the creativity. Investigating those researches, we found that the recent issues of researches on creativity were changing and now they focused on creative instruction methods and behavioral factors. Especially, they were selected as the subject related to the creative education - creative instructional method and program, atmosphere in classroom, and factors of teacher. It means that the past researches which were a little bit conceptive have been changing to material ones which will be able to enhance creativity and its effect. So, in this research, we have developed the program for CPS(Creativity Problem Solving) and verified its effect.

Health Education is very important not only in school or community fields but also in industrial fields. And health education is most fundamental and enthusiastic area in industrial health. The purpose of this study was to analyze the workers' health education needs and the factors which could affect them. The subjects for this study was 855 workers selected from 57 factories in Inchon. The results were as follows: 1. For demographic variables, sex, age, educational level, and income of the workers were investigated. Most of the workers were males (80.2%). Of the respondents, 30∼39 years old were 41.3%. Approximately 62% of the workers were high school graduates. In additions, those who reported they earned 500,000∼800,000 won monthly were 41.9%. 2. Behavioral characteristics of the workers investigated in this study included smoking, drinking and physical activities. Of the respondents, 55.9% were smoking cigarettes, and 26.8% of the workers reported they drank alcohol once or twice a week. The workers who were taking any form of exercise regularly were 31.6%. 3. Occupational characteristics of the workers included working period working hours a day, medical examination, and so on. About 37.6% of the workers had worked 1∼5 years and 53.6% of the respondents were working less than 8 hours a day. More than half of the workers in this study were taking special medical examination(59.3%) and 59.6% of the respondents were working at the production line in the factories. And most of the respondents (69.0%) were mere members of the staffs. 4. For perceived health status of the respondents, 41.1% answered they were healthy. And for the level of health status, health grade 20.4% of the workers were unhealthy. 5. Health education areas the workers in this study wanted to learn were as follows: 1) Mental health 2) Worksite environment 3) Safety control 4) Disease contol. 6. Those who reported having ever received health education in the factories were 20.9%. 7. Women had more health education needs in personal health care, disease control and family health areas than men. Each age group had different health education needs in all health areas and the differences were significant statistically. 8. The workers who had received special medical examination had more health education needs in worksite environment, safety control, and disease control areas than those who had received general medical examination. The lower the satisfaction of the work and the working environment was, the higher the health education needs of worksite environment area were. 9. For the levels of health status healthy workers were more likely than unhealthy workers to have health education needs in all health areas.

In this study, the bacterial communities distributed in sea water of the whitening areas of Gangjeong and Seongsan, Jeju-do have been analysed using the PCR amplification of 16S rRNA to obtain fundamental data and information on relationship of the whitening phenomenon and microbial ecosystem. In Gangjeong, diverse bacteria such as Alcanivorax, Paracoccus, Damselae, Pseudomonas, Rhodowlum, Silicibacter, Suiftobacter, and Roseobacter have been found, and Alcanivorax was the most abundant clone. The most abundant clone from Seongsan was Pseudomonas, of which Pseudomonas tolaasii and Pseudomonas mandeli were most abundantly occurred in the frequency of approx44% and 24%, respectively. Approx4% of the bacterial clones closest to Verrucomicrobiales and other unidentified clones were also fecund in Seongsan, suggesting there is a great discrepancy between bacterial communities from the whitening areas of Seongsan and Gangjeong. The mean temperature, chlorine concentration, pH, and dissolved oxygen (DO) of the sea water of Gangieong and Seongsan in August of 2001 (sampling period) was $27^{\circ}C$~$27.5^{\circ}C$, 30.24~30.60%, pH 8.23~8.36,7 .20~7.28 mg/ι, suggesting other environmental factors except far the factors mentioned above might result in difference of bacterial communities distributed in both areas.

This study was performed to provide fundamental data for long-term geomorphic predictions of estuarine sandbars in the Nakdong River. We monitored the geomorphic changes of Jinudo (Jinu Island), which is located on the far-southern side of the first western sandbar. We evaluated the temporal and spatial dynamics of the sandbar and the relationship between erosion and deposit speed with environmental factors. We found that: 1) The south side of Jinudo showed very rapid water channel closing and shoal generation. This phenomenon was more obvious during autumn (September and October) than during spring, with greater water depth reduction and variation between sides. 2) The mean deposit speed for Jinudo was approximately 0.85 mm/day. The deposit speed was 1.32 and 1.26 mm/day for the east and south sides of Jinudo, respectively. The maximum deposit and erosion speeds were 27 mm/day and 26 mm/day in July and December, respectively, on the east side of the island. 3) Mean surface deposit size was 0.18-0.26 mm. The newly deposited sandbar had a rotatively larger deposit size than the original land. 4) Correlation analysis showed that, on the southern side of the island, deposit activity prevailed in the winter due to low precipitation and a northerly wind, while erosion was dominant in the summer due to high water flow and a southerly wind. In contrast, the correlation analysis for the eastern side of the island showed that deposition is dominant when water flow is high. These results indicate that geomorphic dynamics vary among island sides.

The paradigm of the use and management of natural resources is changing. Wise use of natural resources can be achieved by enhancing their conservation value and, at the same time, taking them as an opportunity for regional development. It leads to an idea of pursuing regional development by making good use of natural resources. In this paper, natural resources were classified as living species resources, ecosystem and landscape resources, and non-living resources. The resources were divided into 27 detailed analysis indices. The administrative boundaries of 165 municipalities in Korea were defined as spatial analysis units. Finally, a spatial database of natural resources was built. To classify the regional types, we conducted factor analyses with a detailed index of natural resources and a cluster analysis with the factor value. As the result of the factor analysis, six factors have been deduced as follows: forest resources, landscape resources, coastal ecology resources, inland water resources, landform resources, and ecology visit resources. In addition, the cluster analyses were conducted for the points of the factors drawn. The final classification consists of nine groups, and appropriate methods for each regional development have been suggested. Results of this study will contribute to providing fundamental materials for site selection and objective-setting for regional development policies and planning in consideration of natural resources.

Recent economic slump is making the construction industry's overall construction business environment worse. Contractors which are under the legal management and/or walk out are to the brink of 25 companies according to the Construction association of Korea released in 2011. It means that existing construction companies are required to transform the fundamental ideology of existing operation framework, and besides, existing companies should be transformed to service industry in order to proceed further into the developing future industries. In this study, it will be chosen the internal marketing related factor like 'Satisfying employees, internal customer, are the first thing to do in order to satisfy external customer.' which is about existing service industry field before its implementation in construction companies. In addition, appropriateness test will be performed including both interactions between each of the factors affect mutually and looking into any management improvement effects on contractors. And also, this proposal is suggested by approaching with internal marketing strategy which is both paradigm shift for customers by construction company members and another internal communication way as a means of overcoming the crisis of overall construction industry under currently happening.

This study applied each Neural Networks theory and Fuzzy Set theory to improve accuracy in remotely sensed images. Remotely sensed data have been used to map land cover. The accuracy is dependent on a range of factors related to the data set and methods used. Thus, the accuracy of maps derived from conventional supervised image classification techniques is a function of factors related to the training, allocation, and testing stages of the classification. Conventional image classification techniques assume that all the pixels within the image are pure. That is, that they represent an area of homogeneous cover of a single land-cover class. But, this assumption is often untenable with pixels of mixed land-cover composition abundant in an image. Mixed pixels are a major problem in land-cover mapping applications. For each pixel, the strengths of class membership derived in the classification may be related to its land-cover composition. Fuzzy classification techniques are the concept of a pixel having a degree of membership to all classes is fundamental to fuzzy-sets-based techniques. A major problem with the fuzzy-sets and probabilistic methods is that they are slow and computational demanding. For analyzing large data sets and rapid processing, alterative techniques are required. One particularly attractive approach is the use of artificial neural networks. These are non-parametric techniques which have been shown to generally be capable of classifying data as or more accurately than conventional classifiers. An artificial neural networks, once trained, may classify data extremely rapidly as the classification process may be reduced to the solution of a large number of extremely simple calculations which may be performed in parallel.

Nagoya Protocol designed to establish criteria about material trade of biological genetic resources(ABS) was adopted in the 10th conference of the Parties to the Convention on Biological Diversity. In the course of the negotiation for adoption of the protocol, there was conflict between developed and developing countries, resource-rich and poor countries, and multinational corporations and environmentalists. This study investigates conflict process, subjects, issues and major factors in the negotiation case, and analyzes the negotiation by using the Conflict Management Process. To develope conflict management strategies for various conflict cases, we examine previous studies and analyze the intersectional conflict factors of this case and general cases, such as Fundamental side, Resource-allocation side, and Communication/Information-sharing side. These analyses of conflict prevention/resolution of the ABS negotiation show the importance of building mutual trust among stakeholders, enhancing mediator training, and constructing appropriate legislative/policy systems for successful conflict management.

Visual messages are fundamental elements for performing communication and indicate the signs which are delivered from the communicator to the communicatee via channels, Generally, we can classify visual messages into two groups; linguistic factors which are rational and deliver abstract concepts and unlinguistic factors which are mental and can be expressed concretely. Especially, web site with receivers' low attention and concentration need images which can attract their attention to visual messages. That is, web site is a medium which allows us to feel visual and emotional experiences. We can call it a standard of sign systems which are consisted of various styles of digital texts. The main purpose of this study lies in that we'll analyze how homepage introductory page as one of the forms of digital text conduces a meaning action to the receivers and that we'll apprehend the structures of images and different types of signs via a semiotic approach and analyze the underlying meaning of the messages. In order to survey the structures of images we'll look into the attitude toward perceiving messages by using semantic differential method which has been developed mostly by Osgood and analyze the visual images by adopting sign types of Fuss. As the signification is created by combining signs, it is significant that we'll analyze the meaning of sings between the transmitters and receivers from the semiotic viewpoint and study the signification systems.

In recent years, natural healing space studies have been done in health care and forestry. However, previous studies have focused on healing effects of natural elements in interior space or natural landscape view. And there is a limit to using the evidence for healing space design. The aim of this study is to discover the relationship between types and effects of healing space for evidence-based design. This study compares and analyzes the mayor images, psychological restorativeness, and satisfaction to identify the effects and differences of natural trail, designed trail, natural shelter, and designed shelter by types of forest space. Collected data is analyzed with a factorial analysis, valiance analysis and multiple regression analysis in SPSS 18.0. The results of this study are as follows: 1) Among five factors consisting psychological restorativeness, natural trail can be achieved with 'being away' and 'compatibility' and designed shelter can be achieved with 'fascination' and 'coherence'., 2) Psychological restorativeness values higher in images with higher excitement, brightness, vitality, and beautifulness as well as in images with lower level of disorder., 3) Among five factors consisting psychological restorativeness, higher forest satisfaction can be achieved with a higher level of 'being away' and 'coherence'. In conclusion, this study contributes to providing fundamental information for design guidelines of healing spaces through identifying the characteristics of healing environment by types of forest space.
