The purpose of this study were to develop a smoking preventive education program for elementary students and evaluate it's effectiveness. This study was a quasi experimental study under the nonequivalent control group with pretest-posttest design. The subjects of this study were 62 who are attending elementary school(31 for each group), 2 different district elementary school. The subjects were matched by grade, similar in anti-smoking educational background of smoking, as well as their residence and income level of their families. The instruments used in this study was 18 criterion referenced test items modeled by Dick & Carey that were developed by researchers for evaluating the subjects' knowledge and attitude about smoking. A pretest was administered a week before treatment The program given to the experimental group is composed of the texts explaining the poisonous substances in tobacco, social and cultural harmfulness of smoking to the body and psychology, indirect smoking, smoking of pregnant women, motives of smoking, refusal skills of smoking; and for the subjects' understanding and the better results of study - pictures, role play, discussion, text through computer based multi-media, puzzle searching for hidden pictures, cross-word puzzle, and finally compensation. The data were collected for 50 days form mid- September to the end of October in the year of 2000, composed of formative evaluation, pre-test and summative evaluation via 2 sessions. Accordingly, the collected data were analysed by t-test, paired t-test, repeated measure ANOVA by the SAS program. This research summarize the findings as follows; 1. There was a significant difference in knowledge between the experimental group(after 1 wks t=10.4680, p=.0001; after 4 wks t= 9.310, p=.0001) and control group(after 1 wks t=0.0420, p= .9669; after 4 wks t= -0.378 p=.7079) in between the results of 1 and 4 week after education in summative evaluation (F=27.45, P=.0001). 2. There was non statistical significant difference in attitude between the experimental group (after 1 wks t=1.2292, p=0.2286 ; after 4 wks t=1.330, p=0.1935) and control group (after 1 wks t=0.1819, p=0.8569 ; after 4 wks t=0.2970, p=0.7685) in between the results of 1 and 4 week after education in summative evaluation(F=0.71, P=0.494). To sum up, the statistics of conclusive analysis evaluative for the children under school age of the 'knowledge acquisition' about smoking harmfulness. On the other hand, as there was already sound attitude about smoking, the evaluation of attitude was non significant difference between control group and experimental group, just there was partially significant difference.

(Background) Recent biotechnological breakthroughs are shedding new lights on various ethical and legal issues about human biological material. Since Rudolph Virchow, a German pathologist, had founded the medical discipline of cellular pathology, issues centering around human biological materials began to draw attention. The issues involving human biological materials were revisited with more attention along with series concerns when the human genome map was finally completed. Recently, with researches on human genes and bioengineering reaping enormous commercial values in the form of material patent, such changes require a society to reassess the present and future status of human tissue within the legal system. This in turn gave rise to a heated debate over how to protect the rights of material donors: property rule vs. no property rule. (Debate and Cases) Property rule recognizes the donors' property rights on human biological materials. Thus, donors can claim real action if there were any bleach of informed consent or a donation contract. Donors can also claim damages to the responsible party when there is an infringement of property rights. Some even uphold the concept of material patents overtaking. From the viewpoint of no property rule, human biological materials are objects separated from donors. Thus, a recipient or a third party will be held liable if there were any infringement of donor's human rights. Human biological materials should not be commercially traded and a patent based on a human biological materials research does not belong to the donor of the tissues used during the course of research. In the US, two courts, Moore v. Regents of the University of California, and Greenberg v. Miami Children's Hospital Research Institute, Inc., have already decided that research participants retain no ownership of the biological specimens they contribute to medical research. Significantly, both Moore and Greenberg cases found that the researcher had parted with all ownership rights in the tissue samples when they donated them to the institutions, even though there was no provision in the informed consent forms stating either that the participants donated their tissue or waived their rights to ownership of the tissue. These rulings were led to huge controversy over property rights on human tissues. This research supports no property rule on the ground that it can protect the human dignity and prevent humans from objectification and commercialization. Human biological materials are already parted from human bodies and should be treated differently from the engineering and researches of those materials. Donors do not retain any ownership. (Suggestions) No property rule requires a legal breakthrough in the US in terms of donors' rights protection due to the absence of punitive damages provisions. The Donor rights issue on human biological material can be addressed through prospective legislation or tax policies, price control over patent products, and wider coverage of medical insurance. (Conclusions) Amid growing awareness over commercial values of human biological materials, no property rule should be adopted in order to protect human dignity but not without revamping legal provisions. The donors' rights issue in material patents requires prospective legislation based on current uncertainties. Also should be sought are solutions in the social context and all these discussions should be based on sound medical ethics of both medical staffs and researchers.

Increasingly advanced Information Technology (IT) has changed the operator so as to create more diversified and advanced traffic information demand. To deal with the changing demand in private sector, a concept of on-demand traffic information has been rapidly introduced. However VMS, a product of the first generation of ITS, which was designed to provide the unspecified individuals during driving the car with the basic level of traffic information by the public failed to actively change itself in such a changing pattern. This study was intended to describe the VMS system (tentatively, FM-VMS) which was further developed to accommodate the needs favoring the sophisticated PDA with the public role of providing the unspecified individuals with the equal information. FM-VMS introduced in this study is the device designed to transmit the voice and message to the drivers through the radio information device mounted on a car. A core technology is, unlike FM-DARC and RDS, the Water Making technology which directly inserts the digital signal into FM frequency in use. It's been currently used for broadcasting and security purpose. A detection rate as a result of testing FM-VMS system using Water Making technology was 90% or more in voice and message within 20m from test VMS. When a public-developed VMS information could be transmitted using FM frequency to the relatively vulnerable users (vulnerable to traffic information) in voice on a real-time basis to provide the regional traffic information, and furthermore, VMS message could be received through radio liquid using FM frequency only, it would obviously bring about the innovation in ITS as well as pave the way for creating the new added value down the road.

BACKGROUND: Genetically modified (GM) crops must receive relevant regulator's authorization before they can be sold as seed or used food, feed and processing. Before approving any GM crop, the relevant government ministries are required to examine environmental risk assessment to make scientifically sound and socially acceptable decisions. But one of the least studied and understood areas in the environmental risk assessment of GM crops are their impact on soil microbial community. METHODS AND RESULTS: Recently, advanced methods have been developed to characterize the soil microbial community in various environments. In this study, the culture-dependent and culture-independent technical approaches for profiling soil microbial communities are summarized and their applicability to assess GM crops are discussed. CONCLUSION(S): We concluded that the effect of GM crops on soil microbial community need to be assessed on a case by case basis. The combination of culture-dependent and culture-independent method was necessary for reliable and detailed assessment of effect of GM crops on soil microbial community.

In this paper, We examined auditory threshold and critical ratio of amberjack seriola dumerili, in the Jeju Island coastal waters, to find out hearing ability of the fish. The auditory threshold level, critical ratio and hearing index of amberjack were determinded by conditioning method using a sound coupled with electric shock in the condition of ambient noise or white noise in an experimental water tank. The audio-signals of pure tone and electric shock were from 80 HZ to 800 Hz and DC 7 V, respectively. Values for the critical ratios were calculated in terms of the masked thresholds using the noise projected to stable spectrum levels at all measurement frequencies of background noise. Masking noises were in the spectrum level range of 65 dB∼75 dB $(re 1{\mu}Pa\sqrt{Hz})$. The auditory thresholds of amberjack within the test the frequencies were most sensitive at 300HZ as 94.5 dB. The critical ratios of fishes ranged from 36.4 to 52.8 dB. The noise spectrum level that started masking was about 58∼72 dB within frequencies.

Musical is produced by multiple specialists including director, writer, composer, lyricist, choreographer, music director, actors/actresses and so on. For the success of one musical, all the people with different background should demonstrate their creativities. The basic frame of a work is made by writer, composer and lyricist first unless it is a licensed musical. They are called as Creative Team, and also director, choreographer, actors/actresses and staff are called as Production Team. Both teams are collectively called as Creative Staff. Then, the secondary creative staff members may participate in the work depending on the production size, and each team can consist of the members such as music director, stage designer, sound designer and so on. The staff related to music in Creative Team of the musical is developed with the initiation from the music supervisor who decides the musical color and genre of the work, the fragmentation and the specialization. However, composer or music director takes these roles in charge in Korea. This study aims to establish the roles and concept of vocal coach according to the fragmentation of working process and to investigate their roles and needs in the domestic musical industry upon case analysis of musical production processes in overseas. The common things and differences in the roles and the functions between ordinary voice teachers and musical vocal coaches were analyzed and the cases of vocal coach in the Korean musicals were reviewed by the interviews. In addition, creative team system was reviewed in the Korean musicals.

The purpose of this study is to develop contents and an instructional model that support children's dramatic play by integrating the robot and augmented reality technology. In order to support the dramatic play, the robot shows various facial expressions and actions, serves as a narrator and a sound manager, supports the simultaneous interaction by using the camera and recognizing the markers and children's motions, records children's activities as a photo and a video that can be used for further activities. The robot also uses a projector to allow children to directly interact with the video object. On the other hand, augmented reality offers a variety of character changes and props, and allows various effects of background and foreground. Also it allows natural interaction between the contents and children through the real-type interface, and provides the opportunities for the interaction between actors and audiences. Along with these, augmented reality provides an experience-based learning environment that induces a sensory immersion by allowing children to manipulate or choose the learning situation and experience the results. In addition, the instructional model supporting dramatic play consists of 4 stages(i.e., teachers' preparation, introducing and understanding a story, action plan and play, evaluation and wrapping up). At each stage, detailed activities to decide or proceed are suggested.

Pattern recognition is the study of how machines can observe the environment, learn to distinguish patterns of interest from their background, and make sound and reasonable decisions about the categories of the patterns. Color image consists of various color patterns. And most pattern recognition methods use the information of color which has been trained and extract the feature of the color. This thesis extracts adaptively specific color feature from images with several limited colors. Because the number of the color patterns is limited, the distribution of the color in the image is similar. But, when there are some noises and distortions in the image, its distribution can be various. Therefore we cannot extract specific color regions in the standard image that is well expressed in special color patterns to extract, and special color regions of the image to test. We suggest new method to reduce the error of recognition by extracting the specific color feature adaptively for images with the low distortion, and six test images with some degree of noises and distortion. We consequently found that proposed method shouws more accurate results than those of statistical pattern recognition.

Objective: This entire study has two parts. Study I aimed to develop a psychological assessment scale and the study II aimed to investigate the effects of LFN (low frequency noise) on the psychological responses in humans, using the scale developed in the study I. Background: LFN is known to have a negative impact on the functioning of humans. The negative impact of LFN can be categorized into two major areas of functioning of humans, physiological and psychological areas of functioning. The physiological impact can cause abnormalities in threshold, balancing and/or vestibular system, cardiovascular system and, hormone changes. Psychological functioning includes cognition, communication, mental health, and annoyance. Method: 182 college students participated in the study I in development of a psychological assessment scale and 42 paid volunteers participated in the study II to measure psychological responses. The LFN stimuli consisted of 12 different pure tones and 12 different 1 octave-band white noises and each stimulus had 4 different frequencies and 3 different sounds pressure levels. Results: We developed the psychological assessment scale consisting of 17 items with 3 dimensions of psychological responses (i.e., perceived physical, perceived physiological, and emotional responses). The main findings of LFN on the responses were as follows: 1. Perceived psychological responses showed a linear relation with SPL (sound pressure level), that is the higher the SPL is, the higher the negative psychological responses were. 2. Psychological responses showed quadric relations with SPL in general. 3. More negative responses at 31.5Hz LFN than those of 63 and 125Hz were reported, which is deemed to be caused by perceived vibration by 31.5Hz. 'Perceived vibration' at 31.5Hz than those of other frequencies of LFN is deemed to have amplified the negative psychological response. Consequently there found different effects of low frequency noise with different frequencies and intensity (SPL) on multiple psychological responses. Conclusion: Three dimensions of psychological responses drawn in regard to this study differed from others in the frequencies and SLP of LFN. Negative psychological responses are deemed to be differently affected by the frequency, SPL of the LFN and 'feel vibration' induced by the LFN. Application: The psychological scale from our study can be applied in quantitative psychological measurement of LFN at home or industrial environment. In addition, it can also help design systems to block LFN to provide optimal conditions if used the study outcome, .i.e., the relations between physical and psychological responses of LFN.
