  • We reviewed investigation status on turbidity plume in the statement of marine environmental survey(2008 to 2012) associated with marine sand extraction projects. The survey statement from seven marine sand extraction sites (extraction area of Southern EEZ, extraction area of Western EEZ, relocation zone in the Western EEZ, sea area under jurisdiction of Taean-gun, sea area under jurisdiction of Ansan City, and two discrete sea areas under jurisdiction of Ongjin-gun) in the nearshore and offshore of Korea showed that in situ observations were carried out for the dispersion and transport of suspended sediments on two areas (One is a extraction area in the EEZs, the other is an area of coastal sites). However, sampling station and range have not been selected considering physical, geographical factors (tide, wave, stratification, water depth, etc.) and weather conditions (wind direction and velocity, fetch, duration, etc). Especially turbidity plumes originating from three sources, which include suspended sediments in overflow(or overspill) discharged from spillways and reject chutes of dredging vessel, and resuspended sediments from draghead at the seabed, may be transported to a far greater distance outside the boundary of the extraction site and have undesirable impacts on the marine environment and ecosystem. We address that behaviour of environmental pollutants such as suspended solids, nutrients, and metals should be extensively monitored and diagnosed during the dispersion and transport of the plume. Finally we suggest the necessity to supplement the current system of the sea area utilization consultation and establish the combined guidelines on marine sand extraction to collect basic data, to monitor cumulative effects, and to minimize environmental damages incurred by the aftermath of sand extraction.

  • The object of this research is to analyze the contents and amount of articles on gifted education in major daily newspapers dated January 1990 to December 2003, and to review the trend of social perception of gifted education with the passage of time. Following are the research question : 1. How many articles belonging to the same category appeared in the newspapers within the period of time covered by the study? 2. What kinds of articles appeared in the newspapers within the period of time covered by the study? To arrive at the answers to the problems mentioned above, 714 articles on gifted education. The period from 1990 to 2003 were divided into time frames of 5 years to facilitate the analysis of social consciousness regarding gifted education before and after the enforcement of the Early School Entering Law in 1995 and the Law for Promotion of Gifted Education in 2000. The researcher defined Period I as the years from 1990 to 1994, Period II from 1995 to 1999, and Period III from 2000 to 2003. The articles were classified by content which were significance and trend of gilled education, current policies on gifted education, information on gifted education, and social environment of gifted education. The results of the analysis are as follows: (1) The articles from 1990 to 2003 totalled 714. 130 articles were found within Period I, 213 within Period II, and 371 within Period III. Since the year 2000, when the Law for Promotion of gifted education was enforced, the amount of articles considerably increased. The articles on the trend of gifted education numbered 42 within Period I, 49 within Period II, and 81 within Period III, showing a huge increase in the last period. The articles on current policies numbered 56 within Period I, 77 within Period II, and 143 within Period III, numbering the most in the last period. This means that, even before the Law for Promotion of gifted education was enforced, there has been much interest in and discussion of the appropriate educational system for gifted children in preparation for the legal and institutional foundation of such system. Since the enforcement of the law, many institutions were established and the problem became an important social issue. The articles that most frequently appeared were about current policies on and status of gifted education. This category showed the largest numbers through all the three periods and on all the subjects. This subject represented 43.1% of the articles on gifted children within Period I, 36.2% within Period II, and 38.6% within Period III. As to the significance and trend of gifted education, this subject showed a decrease from 32.3% within Period I, 23% within Period II, and 21.8% within Period III. However, the articles in the category of information on gifted education gradually increased from they represented 5.4% of the articles on brilliant children within Period I, 7.5% within Period II, and 8.4% within Period III. The social environment articles showed an increase from Period I to Period II-- from 19.2% to 33.3%, but it went down to 31.3% within Period III. (2) As to articles on the trend of gifted education, there were many such articles found, mainly on researches and trends in other countries. As greater importance is accorded to gifted children and as the recognition of the necessity of providing specific education for them grows, more related studies are conducted and people try to adopt new trends from other countries. For the articles on the current policies of gifted education, most of them were about institutions. This means that many educational institutions have been established since the Law for Promotion of Gifted Education was enforced. Informative articles on gilled education were mostly about distinctive features of gifted children and how to tell who the brilliant children are. This fact shows the importance of identifying gifted children in order to educate them systemically and effectively.

  • This research aimed at understanding recognition of the park's community garden, public evaluation of it, and user awareness of the public enhancement plan. This was based on the problem that arose in the park community garden as public awareness research along with community garden cultivation participation within the urban park. In order to compare recognition differences along with community garden cultivation participation, the researcher conducted an analysis by dividing research participants into a cultivation participant group and non-participant group. As a result first, the cultivation participant group positively recognized the necessity of the community garden compared to the non-participant group. However, they recognized the community garden as a space for private profit, which threatened the public aspect of the park. Second, as a result of evaluating community garden publicness, the non-participant group which was alienated from community garden use, had a negative opinion about the community garden. Third, as a result of researching awareness of the community garden distribution method and consumption to promote publicness of the community garden, the cultivation participant group recognized the community garden as a space for private profit. Therefore, it is necessary for both groups to be aware of the public value of the community garden among the park users for sustainable management and operation. The significance of this research is the direction in the aspect of users to form, manage and operate the community garden in the urban park without damaging publicness of the park or conflicting between the function of the park and the function of the community garden. Henceforth, the researcher expects that this research can be utilized to maintain publicness of the park in respect of formation of the community garden in the park and management and operation.

  • Within the urban area, over the past decades unused land and public land such as streams and road sides have given urban residents a space for farming (urban farms). However, because this use is illegal, farming in unused and public lands could cause conflicts between urban farm users and land owners, degrade the quality of the urban landscape and contaminate the environment. Therefore, the purpose of this study is to provide a way of legalizing these farming practices that have been cultivated in unused urban areas and public lands. This study analyzed the status of distribution and use of the urban farms that have been scattered around urban areas in many different forms. The survey was conducted through on-the-spot investigation and in-person interviews with farm users and those who were operating weekend farms in the Siji region of Daegu Metropolitan City. According to the results of this study, urban farms were mainly found in green areas that were easily accessible from residential districts and prohibited from development. It was also revealed that the nearer to the border of the residential districts the sites of urban farms were, the larger the number of urban farms was. When it comes to the type of land use, although the proportion of urban farms located in farmlands was very high, the proportion of those located on state-owned lands such as roads, railroads and streams was also high, over 1/3 of that of the former sites. Among the users of urban farms, the percentage of users who were farming private-owned land for free was highest and that of state-owned land without permission ranked second. Most people who were farming unused lands or state-owned lands without permission, such as streams, roads, railroads, were the elderly. This shows the potential of farms in urban area as leisure activities spaces for the elderly. Even though this study has limitations in that the survey target area was selected in a certain area and the sizes of all urban farms were not measured by surveying apparatus and instruments, it helps to determine the characteristics of use and distribution associated with the spaces of urban farming, and to raise the importance and necessity of legalizing urban farms cultivated illegally in public land.

  • Trip generation is the first step in the conventional four-step model and has great effects on overall demand forecasting, so accuracy really matters at this stage. A linear regression model is widely used as a current trip generation model for such plans as urban transportation and SOC facilities, assuming that the relationship between each socio-economic index and trip generation stays linear. But when rapid urban development or an urban planning structure has changed, socio-economic index data for trip estimation may be lacking to bring many errors in estimated trip. Hence, instead of assuming that a socio-economic index widely used for a general purpose, this study aims to develop a new trip generation model by type based on the market separation for the variables to reflect the characteristics of various zones. The study considered the various characteristics (land use, socio-economic) of zones to enhance the forecasting accuracy of a trip generation model, the first-step in forecasting transportation demands. For a market separation methodology to improve forecasting accuracy, data mining (CART) on the basis of trip generation was used along with a regression analysis. Findings of the study indicated as follows : First, the analysis of zone characteristics using the CART analysis showed that trip production was under the influence of socio-economic factors (men-women relative proportion, age group (22 to 29)), while trip attraction was affected by land use factors (the relative proportion of business facilities) and the socio-economic factor (the relative proportion of third industry workers). Second, model development by type showed as a result that trip generation coefficients revealed 0.977 to 0.987 (trip/person) for "production" 0.692 to 3.256 (trip/person) for "attraction", which brought the necessity for type classifications. Third, a measured verification was conducted, where "production" and "attraction" showed a higher suitability than the existing model. The trip generation model by type developed in this study, therefore, turned out to be superior to the existing one.

  • Purpose: This study aimed to explore the public attitude toward the development of national health program for cancer survivorship. Based on the results of this survey suggest the necessity of national health program for cancer survivorship. Methods: We surveyed 1,015 adults who were over 20 years of age from the sixteen cities and local districts of Korea. We conducted a telephone survey with a structured questionnaire on the post-treatment care at the nation and on the permission as the handicapped for cancer. Results: Fifty-six percent of respondents answered that post-treatment program at the national level is very necessary and twenty-seven percent replied that it is necessary. Respondents emphasized 'Expanding insurance coverage for post-treatment care' (29.8%) and 'Systematic education and rehabilitation programs after treatment' (25.6%). This study found that a lower educational level [adjusted odds ratio (aOR)=1.36; 95% confidence interval (CI)=1.04~1.77], earning under 300 per month [aOR=1.36; 95% CI=1.04~1.77], being married (60.2%) [aOR=1.79; 95% CI=1.34~2.37] and thought higher level of cancer treatment in Korea than the advanced (64.4%) [aOR=1.56; 95% CI=1.15~2.12] influenced the positive attitude toward a national health program. Sixty-eight percent of respondents answered 'Strongly agree' or 'agree' to permission for cancer survivors as the handicapped. People who have been married (72.4%) [aOR=1.89; 95% CI=1.41~2.53] and who have had a lower educational level [aOR=1.35; 95% CI=1.03~1.78] responded that they agree more to permission for cancer survivors as the handicapped. Conclusion: This study shows the positive public attitude of the public toward the national health program for the cancer survivors.

  • The quality control is needed to ensure the accuracy of medical information and achieved by evaluating the performance of and maintaining the system and practicing various measurements and evaluations. The Korean Institute for Accreditation of Medical Image, therefore, have held educational program for quality control of special medical equipments. The major of programs participants, however, are radiology specialists with only small number of radiological technologists from some hospitals, furthermore, the follow-up education and the share of information between participants and non-participants are insufficient in general, thus, the knowledge level of radiological technologists, regardless of their participation, is relatively low. This study carried out the questionnaire research for the 500 radiological technologists registered in Korean Society of MRI Technology, on the basis of 2008, and performed analysis for five months from May to Oct., 2008. The questionnaires were delivered by post to each radiological technologists and the response rate was 36%(n=180). The results of this revealed that the 86.7% of respondents felt the necessity of inspection on quality management, while only the 27.8% completed the educational program for manager of special medical equipment. and only the half(53.9%) had the knowledge about inspection on quality management. The completion of educational program had no correlations with sex, age, size of occupying hospital, the number of radiological technologists in occupying site and MRI laboratory, career year of general radiologist and in MRI laboratory, and the presence of biomedical engineering department in occupying hospital. The 78.0% of participants at the educational program for quality management held by the Korean Institute for Accreditation of Medical Image had the knowledge about inspection on quality management(p<.05) whereas the 43.9% of the hospitals held such program and the 54.4% of radiological technologists from those hospitals had related knowledge, which indicated that such programs held by hospitals had not effects on the knowledge level of radiological technologists. This indicates also that the contents, methods, and other conditional factors of educational programs are important for the outcome of them.

  • This paper critically reviews the previous discussion over public engagement with science and technology by Science and Technology Studies literatures with a focus on justification and acceptance. Recent studies pointed out that the "participatory turn" after the late 1990s was followed by confusion and disagreement over the meaning and agency of public engagement. Their discussion over the reproduction of the ever-present boundary between science and society along with so-called late modernity and post-normal science and sometimes through the very processes of public engagement draws fresh attention to the old problem: how can lay participation in decision-making be justified, even if we agree that privileging the position of experts in governance of science and technology is no longer justified? So far STS have focused on two conditions for participatory turn-1) uncertainties inherent in experts' ways of knowing and 2) practicability of lay knowledge. This paper first explicated why such discussion has not been logically sufficient nor successful in promoting a wide and well-thought-out acceptance of public engagement. Then the paper made a preliminary attempt to explain what new types of expertise can support the construction and sustainment of participatory governance in science and technology by focusing on one case of lay participation. The particular case discussed by the paper revolves around the actions of a civil organization and an activist who led legal and regulatory changes in wind power development in Jeju Special Self-governing Province. The paper analyzed the types of expertise constructed to be effective and legitimate during the constitution of participatory energy governance and the local society's support for it. The arguments of this paper can be summarized as follows. First, an appropriate basis of the normative claim that science and technology governance should make participatory turn cannot be drawn from the essential characteristics of lay publics-as little as of experts. Second, the type of 'expertise' which can justify participatory governance can only be constructed a posteriori as a result of the practices to re-construct the boundaries between factual statements and value judgment. Third, an intermediary expertise, which this paper defines as a type of expertise in forming human-nonhuman associations and their new pathways for circulations, made significant contribution in laying out the legal and regulatory foundation for revenue sharing in Jeju wind power development. Fourth, experts' conventional ways of knowing need to be supplemented, not supplanted, by lay expertise. Ultimately, the paper calls for the necessity to extend STS discussion over governance toward following the actors. What needs more thorough analysis is such actors' narratives and practices to re-construct the boundaries between the past and present, facts and values, science and society. STS needs a renewed focus on the actual sites of conflicts and decision-making in discussing participatory governance.

  • Based on the preliminary surveys for the occurrences of the Muwellut chrome-nickel mineralized zone ($800km^2$) in northwestern Myanmar, Bophivum area was selected as the detailed exploration area after considering data source, geological potential, metallogenic province, necessity of resource development on target mineral, exploration activity, grade, ore deposit type, nearby operating mine, infrastructure and exploration prediction effect. From 2013 to 2016, KIGAM and DGSE carried out geological and geochemical survey with 1:1,000 scale, magnetic survey(areal extent, $1.672km^2$), trench survey(19 trench, total length 392 m), pitting survey(18 pit, total depth 42.6m), exploration drilling(6holes 600m, 2015; 13holes 617.4m). We analyzed Cr and Ni contents of 77 drill cores with specific gravity in Yangon DGSE analytical center. Considering surface geological survey, geochemical exploration, magnetic survey, trench survey and drilling data, we divided Bophivum area into 8 blocks. Resource estimation are divided into measured and indicated resources. Measured resource is about 9,790t and indicated resource is about 12,080t with the average grade of Cr 11.8% and Ni 0.34%. In case of Bophivum area, if we develop by tying up Webula chrome mineralized zone in the south, it will be possible to upgrade the medium-scale mine. Geologically, the ophiolite belt are distributed in the western and eastern part in Myanmar. So, the exploration technology obtained from exploation in Bophivum area will be helpful to discover the hidden chromitite ore body in Myanmar ophiolite belt in the future.

  • Korea is introducing new animal welfare rearing standards for swine farmers in order to improve the breeding environment of livestock on Korean farms, Korea is establishing a policy to apply to all new farms in 2019 and to all existing farms in 2025. These guidelines are limiting stall breeding of sows after 4 weeks of pregnancy, the light intensity should be above 40lux, the ammonia level should be below 25ppm and the breeding density area should be increased from $1.4m^2$ to $2.25m^2$. In Europe, where animal welfare has been studied and applied for nearly 100 years, the facility specifications and management manuals are available and provided to farmers to introduce proper animal welfare for pigs and to enhance the convenience and utility of farmers who are converting to raising pigs. The EU has established independent standards for each country, and the EU has set the standards for floor facilities to improve animal welfare on pig farms and as applied by farmers. Yet in Korea, there are no methods and techniques for breeding methods that do not use an ordinary stall, except on a few leading farms. There has been no research on the welfare of sows so that farmer could improve sows' living conditions. Thus, farmers can minimize the difficulty of implementing the changing government policies, and they must develop farm turnover policies and specification management manuals to cope with the introduced regulations on sow group housing. We suggest that conducting research and evaluating the level of sows' welfare are important for farmers.
