  • 가뭄으로 인한 영향은 상당 기간 완만히 누적되어 나타나고, 해갈된 후에도 수년 동안 파급효과가 나타날 수 있으므로 모니터링 및 예·경보에 어려움이 있다. 가뭄 리질리언스 확보를 위해서는 지하수개발, 해수담수화, 식수전용 댐 확충 등 구조적 중장기 안정화 방안과 더불어 가뭄 피해를 예측하여 미리 물 자원을 확보하는 비구조적 대응 방안이 같이 이루어져야 한다. 대상지역은 물 부족을 겪고 있는 미급수 지역으로 환경부에서는 구조적 대책으로 샌드댐 설치가 예정되어 있다. 본 연구에서는 비구조적 가뭄 대응을 위하여 하천-취수원 연계 모니터링 및 분석을 수행하였다. 하천에 수위 계측기를 설치하여 시간별 수위를 상시 계측하였으며, 월 1회 유속을 측정하여 일별 유량(공급량)을 모니터링하였다. 이를 통해 도출된 일별 유출량 값은 장기유출모형인 SWAT의 매개변수 검·보정에 이용되었으며, 과거 10여 년간의 유출량(공급량)을 추정하였다. 또한, 취수원인 물탱크에 수위계를 설치하여 낮 동안 수위 변화량을 이용량을 가정하여 일별 수요량을 추정하였다. 최종적으로 일별 수요량-공급량 관계분석을 통해 가뭄에 대응할 수 있는 체계를 구축하였다.

  • This study investigates the issues and suggests reform measures in applying CV methods to the Korea Development Institute's (KDI's) Preliminary Feasibility Test (PFT) of public projects. Most public projects on culture, science and environment evaluated under the PFT system belong to the category of "nonstandard" projects whose outputs are non-marketed, and CV is currently the main tool used for their benefit estimation. A careful discussion and investigation is recommended for the selection of target population, payment vehicle, and number of payment times. Operating expert reviews, focus group interviews, and pre-tests is highly recommended to reduce the potential bias involved in the CV studies. A single or double bounded dichotomous choice format is the most popular design of questionnaire, but we identify several undissolved issues in designing and implementing the format. Some other forms of inducing WTPs may still deserve our consideration. Various specifications of the WTP function need to be tried and tested based on their stability, in particular. Employing a nonparametric approach is also recommended. Treatments of 0 or negative WTPs and protest bids are shown to be the most serious issues that affect the estimation results significantly. We review diverse measures of handling those issues and summarize their advantages and shortcomings.

  • To increase the acceptance of multicultural youth, it is necessary to grasp the factors influencing multicultural acceptance. This study was conducted to provide basic data for a future study for the promotion of multicultural acceptance of adolescents by systematically analyzing research trends in factors affecting the multicultural acceptance of Korean adolescents. From 2008 to 2017, we searched 6,435 papers combining the keywords 'multicultural,' 'acceptability,' 'teenager,' 'middle school' and 'high school,' and analyzed six articles. The qualitative evaluation refers to Community Guide and STrengthening the Reporting of OBservational studies in Epidemiology(STROBE). The results revealed that factors influencing multicultural acceptance include gender, experience of overseas visits, life satisfaction, parental neglect and abuse, parent education, school and community factors, and community awareness. Multicultural acceptance of adolescents in Korea was influenced not only by specific factors, but also by various factors such as individual, family, school, and community. These factors were also found to change with age. Based on the results of this study, it is necessary to provide an environment and education that promote multicultural acceptance.

  • The purpose of this study was to develop the safety theme-based integrated teaching learning process plans for the middle school Home Economics(HE) Instruction and ultimately to contribute for the middle school students to live their safe lives. To achieve the goals of this study, HE curriculum documents from the 1st to the 2015 revision were analyzed and a survey was conducted to identify the middle school students' current status of safety accidents and needs on the HE safety education. The respondents of the survey were the 512 students of one ${\bigcirc}{\bigcirc}$ Girls' Middle School in Busan. And then, the seven integrated themes were selected, each seven integrated theme-networks were formed, and safety theme-based Home Economics curriculum and learning materials were developed. The results of this study were as the follows. The safety education content has continually been included from the first HE curriculum of 1954 to the 2015 revised HE curriculum. The middle school student respondents highly needed the content of 'the methods to deal with sexual violence and prostitution prevention', 'suicide prevention', and 'bullying net' for the HE safety education. All the 42 items were needed for the HE safety education by the respondents. The safety theme-based HE teaching learning process plans developed finally included the seven integrated themes, which were (1) dietary life safety, (2) adolescents' sex and safety, (3) adolescents' relationships with friends and safety, (4) family life and safety, (5) dwelling life and safety, (6) adolescents' egos and safety, and (7) social environment and safety. Each integrated theme consisted of three to six small themes, which amounted to total 28(for 35 lessons). Each small theme was presented with learning objectives and particular goals. The total 157 learning materials including the Home Economics curriculum were developed, which offered learning objectives and content for each safety theme, total 28 teaching and learning plans(for 35 lessons) were developed, which offered specific instructions for the easy implementation of the curriculum in the classroom, 28 PPTs, 25 film materials, four reading materials, 61 workbooks, 14 activity sheets, 16 evaluation sheets, 3 test sheets, 2 reference materials, and 4 learning material models(the refrigerator model, traffic lights for discussions, food tray model and stickers, and food mileage card). In this study, the safety education themes of 'clothing life and safety', 'conflict and safety', 'professional life and safety', and 'consumer and safety' were not addressed because these theme were not needed highly by the respondents. Therefore, for the further development of the teaching learning process plans for the HE safety education, it is necessary to develop and evaluate the teaching learning process plans to address the themes of 'clothing life and safety', 'conflict and safety', 'professional life and safety', and 'consumer and safety'.

  • The purpose of this study is to analyze and evaluate the Cyber Home Learning contents of Earth science area in the basic course of the $10^{th}$ grade. For this purpose, we applied the 'Cyber Home Study Content Quality Control Tool' presented in Elementary Secondary Education e-Learning Quality Management Guidelines (Ver.2.0)' of Korea Education & Research Information Service(2008). The results of Cyber home learning contents analysis are as follow: First, it was presented that the study guide introduced the contents which should be studied for one class, properly. And it was not analyzed that the diagnosis assesment was not completed in the initiative study; Second, it was possible to study choosing the contents fitting the learner's level of learning in the main study, it was comprised of about 10 minutes. Third, it was performed without feedback for incorrect answers in the learning assessment, just the number of wrong questions. And the learning arrangement present the important contents learned in that class, summarizing and arranging again. The results of evaluating the contents in Cyber Home Learning are as follows: First, in evaluation section of instructional design, many text materials which were so difficult for learners to read were explained, being provided. Besides, the systematic structures leaves much to be desired, in view of learners' learning experience, contents, and environment. And in evaluation section of learning contents, the error of contents caused the learning contents not to appear, the amount of learning in each section was found too much. Second, in evaluation section of the strategy for Teaching and Learning, when we mention the strategy of Self Directed Learning, the environment to make learners search for information free and self-study possible was not possessed well. And in evaluation section of interaction, it was found that a simple click caused the learning to go on. Third, in evaluation section of evaluating, it was evaluated that there was wanting in consistency in learning aims, contents, evaluation contents.

  • In this research, we develope a procedure for detecting a random non-stationarity to the individual's purchasing rate in a stationary NED model. On this purpose, we derive the likelihood ratio statistic for a testing null and alternative hypotheses defined as whether there is no significant structural change in a stationary NED model or any. Where the structural change comes from a random non-stationarity(marketing mix activities or seasonality, for example) to the individual's purchasing rate. We also apply the developed method to a panel data for a frequently purchased good. This research could be a solution to include the non-stationarity in a stationary NED model. We also expect that the developed model could give a signal for an early detection of significant changes in marketing environment, and a mean for a measurement of the effects of marketing mix activities.

  • Recently, ISM(Industrial, Scientific and Medical) equipments that exceed 50 watts were expended at home, medical institutions and industrial sites. Therefore, the equipments that are subject to permission have been significantly increased. So, the present permission system that individually permits each equipment and inspects all equipments has a limitation. Thus, it is also difficult to reflect the environmental changes. In this paper, we reviewed the ISM management system in major foreign countries and domestic, and then proposed an improvement scheme of ISM management system for domestic environment. These results will be useful for revitalization of domestic industry related to ISM equipment and an efficient management of ISM equipments in the future.

  • The object of this series of experiments was aimed for the systematic and long-term radioactivity monitoring through indirect search of C-14 concentration level changes in the natural conditions around the operating nuclear facilities. The result of environmental radioactivity level through tree-ring analysis is increased after operating nuclear facilities and such a level can be proved to relate power generation closely. The measured result of ${\delta}^{13}C$ through the treatment of cellulose can be showed the level -30‰. This figure is very different from one which is measured the -17‰ of air sample by passive air sampling and -8‰ of air sample by active air sampling. And these differences can be assumed as isotope fractionation by photosynthesis, but the problem is more study as needed.
