The study was aimed at verifying the effectiveness of Book-Coding reading education as a reader activity of older elementary school children at a time when high-dimensional thinking abilities were formed. To this end, 30 fifth-grade children of N Elementary School in N-si, Gyeonggi-do, comprised of 15 students from a reading education program using Book-Coding, and 15 students from a reading comprehension program, and applied the reading education program over a total of 12 sessions. The main results of the study are summarized as follows. First, when the effects of the convergence reading education program using Book-Coding on the logical thinking ability of the students in the upper grades in the elementary school were analyzed, all the six sub-factors of logical thinking ability, that is, conservation logic, proportional logic, variable controlling logic, probabilistic logic, correlational inference logic, and combinational logic, were proved to have statistically more meaningful difference than the group writing a book report. Second, the analysis result of the influence of the convergence reading education program using Book-Coding on the creativity of the students in the upper grades of the elementary school showed that all the 13 elements of curiosity, persistence, effectiveness, independence, adventurousness, openness, knowledge, imagination, originality, sensitivity, fluency, flexibility, and accuracy were statistically meaningfully different compared to the book report group. Third, when it was analyzed how the convergence reading education program using Book-Coding affected the creative personality of the elementary school students, all the six factors of curiosity, task commitment, independence, awareness of risk, and openness of thinking, and aesthetics were found out to have a statistically more meaningful difference than the group that wrote a book report.

최근 정부의 신북방정책 추진에 따라 수자원분야에서는 동북아지역 국제 공유하천을 중심의 물 정보 및 연구협력 기회 확보와 지정학적 특성을 고려한 지역 현안해결 중심의 연구가 재조명 되고 있다. 두만강은 이러한 동북아의 중심에 위치하고 있으며, 중국, 북한, 러이사의 국경을 따라 흐르며 지역 수자원의 대부분을 공급하는 국제하천이다. 또한, 지난 2018년 5월에는 하구유역이 람사르(Ramsar) 습지로 승인됨에 따라 철새 등을 포함한 생태가치의 중요성도 크게 증가하였다. 하지만 이 지역은 유역의 지정학적 민감성과 접근이 제한된 관측 정보들로 인해 그 수자원·환경 효용성을 정확하게 파악할 수 없을 뿐만 아니라, 최근 기후변화에 따른 영향으로 홍수, 가뭄 등의 수재해와 수질오염 등의 문제가 발생하고 있어 가용한 기술기반의 직·간접적 접근을 통한 장기수문 및 환경변화 등에 대한 분석과 관리방안 수립 등의 연구가 필요하다. 본 연구에서는 이러한 미계측 두만강 유역을 대상으로 우선, 가용한 위성자료 및 광역지표모형(MERRA-2) 기반 NASA POWER(Prediction of Worldwide Energy Resource) 수문기상 자료와 SWAT(Soil and Water Assessment Tool) 모형을 활용하여 장기 수문영향을 평가하고자 한다. SWAT 모형은 전 지구적으로 활용 가능한 격자 해상도 약 30m의 위성기반 수치표고모형(DEM), 광역 토양도, 지역 토지이용도 자료를 활용하여 두만강 유역을 전체 19개 소유역 및 18개 하도, 138개 HRUs의 수문분석 단위로 구축하였으며, 모의는 미국 NOAA NCDC(National Climate Data Center) 및 중국 CMDC(China Meteorological Data Service Center)의 주요 관측지점에서 선별한 총 13개소의 위치에 대해 재분석된 기후/기상자료들(NASA POWER 강수, 기온, 풍속, 상대습도 및 일사량)을 적용, 1990년에서 2019년까지의 30개년도 연속자료를 구축활용 하였다. 한편, 모형의 검·보정은 앞서 언급한 관측 자료의 부재로 과거 문헌 등을 통해 파악할 수 있는 연 단위 수자원 총량 등을 활용해 진행코자한다. 아울러, 향후는 최근 활용 가능한 장기 위성관측 강수량을 적용, 재분석 자료 결과와의 비교를 통해 상호 분석 오류를 줄여나갈 수 있을 것으로도 판단된다.

1973년 기상관측 이후 5년에서 7년 주기로 전국적 및 국지적 가뭄이 반복되고 있으며, 2010년을 기점으로 매년 가뭄이 발생하는 등 지역적 가뭄의 발생빈도도 증가하고 있다. 이러한 가뭄은 특히 농작물 생육 및 수확과 같은 농업 부분에서 가장 큰 영향을 미치고 있으며, 가뭄의 선제적인 대응을 위해서는 시공간적인 진행 상황이나 강도를 객관적인 기준을 통해 파악해야 한다. 가뭄의 경우 2016년 범부처 가뭄예·경보제를 시범 운영하여 2017년부터 본격적으로 시행하고 있으며, 매월 시군별 지역에 대한 농업용수의 가뭄 상황을 4단계 (관심, 주의, 경계, 심각)로 구분하여 발표하고 있다. 농업가뭄의 경우 저수지, 양수장과 같은 농업수리시설의 능력에 대한 의존도가 높아 가뭄이 발생했을 경우, 용수공급시설에서 용수공급이 가능한 물의 양을 파악하여 가용용수 능력을 평가함으로써 농업가뭄에 대응할 수 있는 정도를 파악해야 한다. 현행 농업용 저수지 물 관리 운영의 경우 과거 경험에 의존하는 실정으로 용수관리 및 물 관리자의 개인 역량에 따른 편차가 발생하고 있다. 또한, 전국 모든 농업용 저수지에 평년 저수율을 적용하여 가뭄단계를 산정하기 때문에 개별저수지의 특성을 반영하지 못하는 한계를 갖고 있다. 본 연구에서는 가뭄예·경보를 위한 농업용 저수지 저수율의 가뭄단계별 기준을 개선하고자 한국농어촌공사 관할 농업용 저수지 3,400개를 대상으로 백분위수 (Percentile)를 적용한 저수지 이수관리 기준을 제시하고자 한다. 또한, 빈도분석 및 연속이론 (Run theory)을 적용하여 과거 및 현행 가뭄 판단 및 이수관리 기준들의 가뭄에 대한 선제적 대비능력 및 민감성을 비교·분석하고자 한다.

This study examines Korean representation of the biotechnology and psychological factors which can influence lay people's perception and attitude about biotechnology. Korean college students(N=433) and lay adults(N=90) whom had college education participated in the study. Participants of the study 1 were asked to list words which comes to mind when associate with the biotechnology in broad sense, and several specific applications in health, medicines, agriculture and research. Participants of the study 2 were asked to list possible benefits and costs of biotechnology and their specific applications. In study 3, Participants responded the questionnaires about perceptions and attitudes of biotechnology. Korean people associated the biotechnology with its costs or risks and benefits. Korean college students mainly got the informations of the biotechnology from TV, newspapers, or internet. They trusted the scientist group and NGO group on their judgements about the assessment of risk and benefit of the biotechnology. College students showed the positive attitude with the applications in medicines and negative attitude with the applications in agriculture and public using of individual's genetic information. The radicalism, sensitivity in behavioral activation system, and trust/cynicism were to be found as a significant influencing factor for interest/knowledge and behavioral intention in related with biotechnology. Finally, more extensive knowledge of biotechnology did not lead to greater acceptance of it.

Transgenic tobacco plants expressing calmodulin derivative($lys{\rightarrow}ile$ 115 calmodulin) and hygromycin resistance genes or hygromycin resistance gene alone(control) were generated by Agrobacterium-mediated DNA transfer. Seeds obtained from the transgenic plants($F_o$) were tested for resistance to hygromycin and the expected 3 : 1 ratio was observed. The expression of calmodulin derivative in the tobacco plants was identified by a combined method of Western blot and Chemiluminescence. The effects of surface sterilizers on the germiation of seeds from transgenic tobacco plants were tested in Murashige and Skoog agar medium. Seeds obtained from transgenic tobacoo plants expressing the calmodulin derivative showed no fungi contamination with normal germination by treating with sterilized water alone or sodium hypochlorite(2% effective chlorine). In contrast, seeds from the control transgenic tobacco plants showed severe contamination with fungi by treating with sterilized water alone and showed no contamination with normal germination by treating with sodium hypochlorite(2% chlorine). The effects of calcium concentration on the germination of seeds from transgenic tobacco plants were tested in Murashige and Skoog agar medium. Seeds obtained from transgenic tobacco plants expressing the calmodulin derivative showed better germination frequency than that of the control transgenic tobacco seeds in the medium containing 30 mM $CaCl_2$. The data raise the possibility that the expression of calmodulin derivative gene in tobacco plants could increase adaptability of the seeds to environmental stresses.

This study conducted a survey of 249 adults to determine the effect of oral health beliefs on total body health by mediating subjective oral health. The results showed that the subject's oral health belief averaged 3.75 points, the component of oral health belief was 3.41, the severity 3.73, the importance 4.22 and the benefit 4.19, and the subjective oral health was 3.77 points and the overall health was 3.06. Oral health belief and subjective oral health were found to have a correlation of wealth (r=-0.54, p<0.001), oral health belief and total body health also had a correlation of wealth(r=-0.30, p<0.001), subjective oral health and total body health had a relationship of justice(r=0.47, p<0.001). It was also found that oral health beliefs affect total body health by fully mediating subjective oral health. Based on these findings, it is thought that oral health education programs for adult oral health beliefs can be developed and utilized as basic data for comprehensive general health care, including oral health care, based on correct knowledge and attitudes.

Since the inception of Internet Protocol TV's real-time service on January, 2009, technological challenges and lack of content diversity of IPTV have been cited as problem areas. While past researches focused on IPTV's technological, industrial and policy facets, this research surveyed the viewers' viewing and usage patterns, and the level of service satisfaction among actual audiences of MegaTV, SKBroadband, and LGTV since January. The results show that subscription fee and content types were the two dominant determinants in audience's choice of a particular IPTV company. The high users of IPTV were on average aged between 30-39, and women tended to be heavier users than men. The surveyed audience also regarded IPTV to be more similar to the Internet than any other medium such as Cable TV and Satellite TV. IPTV audience cited 'lifestyle service' and 'additional service' offerings to be highly relevant to their usage and satisfaction; interactive service and educational service also showed high correlation to usage and satisfaction. The most watched contents on IPTV were domestic TV series, followed by foreign movies and variety shows. 'Fees for additional features,' 'lack of real-time terrestrial TV service', and 'lack of content variety' were the major areas of concern for IPTV viewers. They answered that the monthly fee was the most important factor in the selection of IPTV. Use of pay-per-view contents and add-on interactive service fees were also seen as problematic. With regards to future usage, the IPTV audience revealed that they were very sensitive and reluctant to pay for additional services. While existing researches concentrated on IPTV's technological problems and lack of content diversity, this study illuminated the more pragmatical side of the viewers, namely, the importance of price in audience's selection of an IPTV service provider. From these results, it is recommended that, before doing anything else, the service providers try to meet the audience's expected price points in order to garner the full potential of IPTV and the attendant mass audience.

Objective : The purpose of this study is to investigate the influence of internal shame and self-control on interpersonal relationships in stroke patients, and to provide evidence and information necessary for clinical trials by analyzing the relationship. Methods : For this study, 150 stroke patients receiving occupational therapy services at institutions where occupational therapists work in Jeollanam-do and Chungnam regions were targeted through email and mail from March 1, 2019 to April 30, 2019. The questionnaire was conducted using general characteristics, Relationship Change Scales(RCS), Self-Control Scales(SCS), and Internalized Shame Scale(ISS) questionnaire. Descriptive statistical analysis was performed for the general characteristics of the study subjects, and t-test and one-way batch variance analysis (ANOVA) were used to compare interpersonal relationships according to general characteristics. The relationship between internalized shame, self-control, and interpersonal competence was analyzed by Pearson's correlation coefficient, and multiple regression analysis was performed to determine the factors affecting interpersonal relationships of stroke patients. Results : As a result of comparing interpersonal competence according to general characteristics, significant differences were found in terms of age and education level. Interpersonal relationships and internalized shame, internalized shame and self-control showed a negative correlation, and self-control and interpersonal relationships had a positive correlation, but self-control was the sub-factors of interpersonal relationships such as openness, sensitivity, intimacy, It was not statistically significant with the communication item. In addition, the items of inadequacy (β =-0.32) and adventure seeking (β =-0.23), which are sub-areas of internalized shame, affect the negative direction, and physical activity (β =0.22), which is the sub-area of self-control and the self-centered (β =0.24) item was found to have an effect on the positive direction. Conclusion : Therefore, additional research is needed that can operate a rehabilitation treatment program that applies various psychological factors for the formation of interpersonal relationships among stroke patients.

This paper examines the role of accounting conservatism on investment expenditure for non-financial Korean listed firms around the 2007-2008 global financial crisis using a differences-in-differences design. Specifically, this paper examines the association between an ex ante classification of firms by their level of accounting conservatism prior to the credit crisis and the ex post magnitude of the decline in investment. Consistent with prior literature, this study found that firms experienced a decline in their investment when hit by the financial crisis (Campello et al. 2010). And also this study found that firms with more conservative financial reporting experienced a smaller decline in investment activity following the financial crisis than did firms with less conservative financial reporting. Together, the results suggest that negative shocks to the supply of external finance hampers firm-level investment and that conservative financial reporting can lessen the sensitivity of firms' investment to such negative shocks. Next, this study shows that the magnitude of our findings is greater for firms more likely to suffer from underinvestment (as opposed to overinvestment). Firms that are financially constrained or have greater demand for external finance are more likely to experience underinvestment. Consistent with the predictions, this study finds stronger benefits of conservatism for firms that face relatively greater costs in raising external capital (i.e., financially constrained firms) or that have a relatively greater need to do so (i.e., firms that lack internal financial resources). This study also finds that the role for conservatism is greater in firms with a higher level of information asymmetry, consistent with the notion that conservatism mitigates financing frictions arising from information problems.
