정책 명칭과 정보 제공이 탈원전 수용성에 미치는 영향: 행동경제학적 접근
하지훈,윤순진 한국환경정책학회 2025 환경정책 Vol.33 No.3
이 연구에서는 정책 명칭(‘탈원전’ vs ‘감원전’)과 정보 제공이 탈원전 정책 수용성에 미치는 영향을 행동경제학적 관점에서 실증적으로 분석하는 것을 목적으로 하였다. 또한 다양한 사회・심리적 요인이 수용성 형성에 어떻게 작용하는지도 함께 검토하였다. 이를 위해 성인 300명을 대상으로 정책 명칭과 통계 정보를 제시한 온라인 설문 실험을 설계하고, 수집된 자료를 분석하였다. 분석 결과, 진보적 정치 성향, 원전 안전성・경제성・친환경성에 대한 부정적 인식, 높은 수준의 기후 행동 실천이 탈원전 정책 수용성에 유의미한 정(+)의 영향을 미치는 것으로 나타났다. 반면, 정책 명칭 차이는 정책 수용성이나 정책 효과 인식에 통계적으로 유의한 영향을 미치지 않았다. 또한 탈원전 정책에 따른 원자력 발전량 변화에 대한 대중 인식과 실제 통계 간 괴리가 뚜렷하게 확인되었으며, 정보 제공 효과는 탈원전 정책에 대한 응답자의 기존 입장에 따라 큰 차이를 보였다. 이러한 결과는 탈원전 정책 수용성 형성이 단순히 정책 용어 선택보다는 정치적 성향, 정보 해석 방식, 기대 수준 등 복합적 요인들의 상호작용에 의해 형성됨을 시사한다. 따라서 논쟁적인 에너지 정책의 수립과 실행을 위해서는 정책 수용자에 대한 보다 정교하고 심층적 이해가 필수적이며, 맥락에 부합하면서도 차별화된 접근이 요구된다. This study aims to empirically examine, from a behavioral economics perspective, how the framing of policy terminology (“de-nuclear power” vs “nuclear phase-out”) and the provision of factual information influence public acceptance of nuclear phase-out policies. In addition, it investigates how various socio-psychological factors contribute to the formation of policy acceptance. To this end, an online survey experiment was designed and conducted with 300 adults, in which both the policy label and statistical information were systematically manipulated. The analysis revealed that progressive political orientation, negative perceptions of nuclear power in terms of safety, economic efficiency, and environmental impact, and a high level of climate action engagement were all positively associated with greater acceptance of de-nuclear power policies. In contrast, differences in policy labeling had no statistically significant impact on either policy acceptance or perceptions of policy effectiveness. The results also revealed a clear gap between public perceptions and actual statistics regarding changes in nuclear power generation under the de-nuclear power policy, and the effect of information provision varied significantly depending on respondents’ prior attitudes toward the policy. These findings suggest that public acceptance of de-nuclear power is shaped not simply by the choice of policy terms but more substantially by the interaction of multiple factors such as political orientation, interpretation of information, and expectation levels. Accordingly, the design and implementation of contentious energy policies require a more nuanced and in-depth understanding of policy recipients, as well as context-sensitive and differentiated communication strategies.

The purpose of this study is to design a model for the development of ‘English lesson plans’ focusing on improvement of cultural understanding in elementary English education utilizing the Internet. This study examined the use of the Internet as a teaching tool for English culture education. The reasons for devising new lesson plans utilizing the Internet are as follows. First, in this fast-paced information era, the Internet allows people to study beyond time and space. The Internet is a necessity in daily life and will play a more leading role in education in terms of content and will be instrumental in the future. It is necessary for the nation and individuals to use the Internet in order to effectively study English. The Internet not only allows for the sharing of information but also drastically changes education of English. Second, it is important that learners understand English culture. It is necessary for learners to learn the target culture as well as the language in order to get rid of false stereotypes or misunderstandings about the target culture, and successfully communicate with native speakers. Third, learners use the Internet as a main source of educational media. There are many ways to learn the target culture in the process of English learning, but these have a number of limitations. One of the solutions to this program is the learning through the Internet. It is a valuable tool for learning the target culture in English learning, and to introduce the Internet as an efficient too for learning the target culture. In order to achiever the main purpose, a background for using the Internet for English education and culture teaching must be established and an investigation of the actual conditions of elementary schoolchildren should be conducted. From a review of research findings that analyzed students’ actual conditions, and English lesson plan for elementary schoolchildren was designed. The basic principles of this leson plan were based on the 7th English curriculum for elementary schools. The lesson plan combined linguistic competences and culture, the objectives of the unit. In conclusion, the results of this study show that the Internet is the most suitable way to teach and learn English. The contents of lesson plans are made of basic Internet-based activities for learners to experience culture-based activities with interest and practice language functions naturally and effectively. This method can also be adjusted both for on-line classrooms and for traditional off-line classrooms. I expect that this study will help Korean media education fields to research new media including multimedia like that on the Internet and introduce new methods of their own.

The purposes of this study are to analyze the merits and limits of flipped learning by suggesting the ALP model for efficient application and to test the effects of the new ALP model. The process of new model and program development is based on ADDIE in this study. This study consists of two steps. First through literature research on the difficulties of the flipped learning, the elements are extracted to develop new model. Second, these elements were placed according to the teaching and learning flow, which resulted in the procedures. As a result, the ALP model was developed. The ALP model is a new model for applying teaching and learning methods for efficient application of the flipped learning. This model was applied to elementary science classes to test its effects in scientific communication skill. Interviews and cognitive survey were also conducted to collect additional information. The results of this study are as follows: There were various difficulties in flipped learning. Based on literature research results, the ALP model and the science programs for elementary students have been developed. The experimental group showed statistically meaningful improvement in scientific communication skill. The scientific communication skill has two subcategories: the forms and the types. According to the form analysis results, the experimental group showed a statistically meaningful improvement in the form of Table and Picture, but not in the form of Writing and Number. With the same reason given previously, this study confirmed that the application of ALP model improves the students’ visual form communication skills such as Table and Picture better than reading form communication skills such as Writing and Number. According to the type analysis results, the experimental group showed a statistically meaningful improvement in “the scientific insistence” type, and “the justification” which is the sub element of “the scientific insistence” type. With this reason, this study suggests that the class applied ALP model gives students more time and opportunities to learn. Though the survey and interviews about the student’s awareness of the class with applied the ALP model, this study showed that students actively exchanged their opinions in the class with applied ALP model. 본 연구의 목적은 거꾸로 수업의 이점과 한계를 분석하여 실제 수업 적용에 효율적인 ALP 모형을 개발하고, 그 효과를 확인하는데 있다. 새로운 모형과 프로그램 개발 과정은 ADDIE 모형을 기초로 하였다. 먼저 거꾸로 수업의 어려움 분석과 관련된 연구들을 분석하여 새 모형의 주요 구성 요소를 추출하였고, 이 요소들을 수업의 흐름에 따라 재배치함으로써 ALP 모형을 개발하였다. 모형은 요약 강의 참여 단계(Attending a Short Lecture), 갭(gap) 이용 추가 학습 단계 (Learning More in a Gap), 학생 중심 학습 수행 단계(Performing Student-centered Learning)의 3단계로 구성된다. 과학적 의사소통능 력에 대한 모형의 효과를 살펴보기 위해 ALP 모형을 적용한 초등 과학 프로그램을 개발하였다. 추가적인 정보를 얻기 위해서 수업에 대한 인식 조사와 실험집단 학생들 중 일부를 대상으로 면담을 진행 하였다. 연구결과는 다음과 같다. 거꾸로 수업의 어려움을 분석한 논문을 살펴본 결과 수업의 흐름에 따라 다양한 종류의 어려움을 확인할 수 있었으나, 주로 사전학습과 관련된 것이었다. 이를 바탕으로 수업 구조적인 변화를 주어 사전학습의 동영상 강의 부분을 다시 교실로 가지고 오고, 자율적인 추가 학습 부분을 교실 밖에 유지하였다. 이를 통해 거꾸로 수업에서 의사소통능력 향상에 도움을 주는 학생중 심학습 시간의 증대를 꾀하고, 거꾸로 수업의 사전학습에서 교사의 준비 부담과 학생의 참여 관련 어려움을 줄이고자 하였다. ALP 모형을 적용한 초등 과학 프로그램을 적용한 뒤에 과학적 의사소통능력 측면의 효과를 살펴본 결과, 실험집단에서 유의한 향상이 있음을 확인하였다. 세부 결과에서는 표와 그림 형태와 주장형과 정당화 유형 에서 유의한 효과를 확인하였다. 이는 학생들에게 학생중심학습의 시간과 기회를 보다 많이 제공한 결과로 볼 수 있으며, 이는 수업에 대한 인식조사나 면담에서도 확인할 수 있었다.

This study is designed to prove the role and effect of ethics codes in professional societies, especially for scientists and engineers working in R&D project groups. The hypotheses of influence on ethical conduct within the sample groups are tested and analyzed by statistical methods. Results show that the age of researchers and the integrity factor among the ethical conduct factors have significant influence on ethical conduct of research groups. The regression model of the ethical conduct factors also indicates a meaningful reference in an application or development of new ethics code in research organizations.
이미지처리를 통한 선박평형수 내 유해수중생물 개체수 측정
하지훈,임효혁,김용혁 사단법인 인문사회과학기술융합학회 2016 예술인문사회융합멀티미디어논문지 Vol.6 No.3
선박평형수란, 선박의 균형을 유지하기 위해서 배에 채우는 바닷물을 말한다. 선박평형수를 통한 외래종 유입은 생태계 교란의 주된 원인이다. 이를 방지하기 위해 IMO(International Maritime Organization)에서는 2004년 선박평형수와 침전물 관리협약을 채택하였다. 협약이 발효될 경우 각국 항만 당국에서는 선박평형수가 협약의 성능 기준에 맞게 배출되는지 확인이 필요하다. 본 논문에서는 이미지처리를 통한 선박평형수 내 유해수중생물 개체수 측정 방법을 제안한다. 부산 신항에서 채취한 선박평형수로부터 3개의 샘플을 추출하였으며, 각 샘플당 서로 다른3개의 grey-scale 이미지를 만들어 실험자료로 사용하였다. 이미지처리를 이용한 자동 세포계수 프로그램인 CellProfiler를 이용하여 본 논문에서 제안하는 방법과 비교하였다. CellProfiler에서 사용한 설정은 사람이 직접 세포계수를 한 결과에 맞춰 경험적으로 결정하였다. 각 이미지에서 CellProfiler와 가장 유사한 결과를 보이는 최적의 임계값을 찾은 뒤 그 평균을 최종 임계값으로 사용하였다. 실험결과에서 제안한 방법은 CellProfiler와 비슷한 세포 계수 결과를 보이면서도 약 10배 정도 빠른 처리 속도를 보였다. Ballast water provides stability and manoeuvrability to a ship. Foreign harmful aquatic organisms, which were transferred by ballast water, cause disturbing ecosystem. In order to minimize transference of foreign harmful aquatic organisms, IMO(International Maritime Organization) adopted the International Convention for the Control and Management of Ship’s Ballast Water and Sediments in 2004. If the convention take effect, a port authority might need to check that ballast water is properly disposed of. In this paper, we propose a method of counting harmful aquatic organisms in ballast water thorough image processing. We extracted three samples from the ballast water that had been collected at Busan port in Korea. Then we made three grey-scale images from each sample as experimental data. We made a comparison between the proposed method and CellProfiler which is a well known cell-counting program based on image processing. Setting of CellProfiler is empirically chosen from the result of cell count by an expert. After finding a proper threshold for each image at which the result is similar to that of CellProfiler, we used the average value as the final threshold. Our experimental results showed that the proposed method is simple but about ten times faster than CellProfiler without loss of the output quality.

Retinaldehyde (RA), vitamin A derivative, is an intermediate between retinol and retinoic acid and has an excellent wrinkle improving effect. In this study, Drug-in-cyclodextrin-in-liposome (DCL) was used to enhance the stability and skin penetration of RA. The complex of RA and hydroxypropyl-beta-cyclodextrin (HP-β-CD) was prepared by the freeze-drying method, and the presence or absence of inclusion of retinal was confirmed by UV-Vis spectrometer, FT-IR and SEM images. RA was captured in HP-β-CD about 95.6% on 1 : 15 (w/w). The retinal-HP-β-CD complex was encapsulated in liposomes using a homomixer and microfluidizer, with an average particle size of 215 ± 4.2 nm and a zeta potential of -31.2 ± 0.5 mv. In the evaluation of the degradation stability of RA, degradation rate of RA-HP-β-CD-liposomes in water was 1.8% higher than RA-liposome (5.8%), RA-HP-β-CD complex (9.7%) and RA alone (37.6%). RA cream (0.05% RA) including RA-HP-β-CD-liposomes was prepared for clinical test with wrinkle-improving efficacy and skin dermis denseness evaluated for 2 or 4 weeks. RA cream showed a significant wrinkle improving effect without skin irritation. In conclusion, it was confirmed that the double stabilization technology using the DCL system contribu tes to the effect of improving skin wrinkles by increasing the stabilization of retinal. 레틴알(RA)은 레티놀과 레티노익애씨드의 중간체로 비타민A 유도체이며 주름개선 효과가 우수하다. 본 연구에서는 drug-in-cyclodextrin-in-liposome (DCL)을 이용하여 레틴알의 안정성을 높였다. 레틴알과hydroxypropyl-β-cyclodextrin (HP-β-CD) 복합체를 동결건조 방식으로 제조하였고, UV-Vis 분광법, FT-IR 및 SEM 이미지로 레틴알의 포접 여부를 확인하였다. 레틴알과 HP-β-CD의 비율이 1 : 15 (w/w)일 때 약 95.6% 포집되었다. 레틴알-HP-β-CD 복합체는 호모믹서 및 마이크로플루다이저로 리포좀에 담지시켰으며, 평균 입자 크기는 215.3 ± 4.2 nm, 제타포텐셜 -33.2 ± 1.5 mv로 나타났다. 레틴알의 분해 안정도 평가에서, 물에서레틴알-HP-β-CD-리포좀의 레틴알 감소율은 1.8%로 레틴알-리포좀(5.8%), 레틴알-HP-β-CD복합체(9.7%), 레틴알 단독(37.6%)보다 높게 나타났다. 레틴알-HP-β-CD-리포좀이 함유된 크림(0.05% RA 함유)을 제조하여, 미간, 이마, 목, 눈가, 입가, 팔자 주름개선 효능 및 피부 치밀도를 2 ∼ 4 주간 평가하였다. 그 결과 레틴알크림은 피부 자극 없이 유의한 주름 개선 효과를 보였다. 결론적으로, DCL시스템을 이용한 이중 안정화 기술은레틴알의 안정화를 높여 피부 주름 개선 효과에 기여함을 확인하였다.

하지훈,김경미,정윤주,박영민,이재영,박진오,박수남 대한화학회 2017 Bulletin of the Korean Chemical Society Vol.38 No.1
Recently, development of biocompatibility functional cosmetic agents as antioxidant or whitening agent has increased. In this study, synthetic cysteine derivatives (DBLS-21, -24, and -33) were developed containing syringic acid and cysteine moieties (l-cysteine ethyl ester, N-acetyl cysteine methyl ester, and N-acetyl cysteine ethyl ester), and their antioxidative and whitening activities were evaluated. The cellular protective effect (τ50) of DBLS-21 was 51.1 min at 50 μM on1O2 -induced hemolysis of erythrocytes. This activity was slightly higher than that of α-tocopherol (43.6 min) as a lipophilic antioxidant. In the melanogenesis inhibitory effect, DBLS-21, -24, and -33 was 1.6-, 1.8-, and 2.5-fold higher than arbutin, respectively. In particular, DBLS-21 and -33 was 112.8- and 6.1-fold higher than arbutin, respectively (293.4 μM) on tyrosinase inhibition activity (IC50 ). But DBLS-24 had no tyrosinase inhibitory activity. These results suggest that cysteine derivatives possess potential for use as an antioxidant agent (DBLS-21) and whitening agents (all derivatives) in cosmetics.
