본 연구에서는 맥락을 중요시하는 수업 절차를 제안하고, 과학 수업을 진행하여 어떠한 효과가 있는지살펴보고자 하였다. 과학지식과 관련이 있는 다양한 맥락 중에서 발견의 맥락과 실생활 맥락을 중심으로 수업을 설계하기 위한 수업 절차를 개발하였다. 맥락중심설계와 이를 적용한 프로그램에 대하여 전문가의 내용 타당도 검증 후 수업을 진행하였고, 학생들의 반응을 확인하였다. 수정⋅보완을 거쳐 완성된 수업 설계의 최종안은 다음과 같다. 맥락중심설계를 4단계 PEAS(1단계 - 맥락 제시하기(Presentation), 2단계 - 맥락 탐색하기(Explore), 3단계 - 맥락 적용하기(Adapt), 4단계 - 정리하기(Share & Synthesize)) 절차로 제시하였다. 과학지식이 어떠한 사회적⋅역사적 맥락에서 생성되었는가(발견의 맥락)부터 실생활에서어떻게 활용되고 있는가(실생활 맥락)까지 폭넓게 다룸으로써 단편적인 지식 습득에만 치우치지 않고, 과학지식의 전반적인 흐름을 경험할 수 있도록 하는 데 목표를 두고 있다. 새롭게 제안한 수업 절차에대한 이해를 돕고, 그 효과를 확인해보고자 5학년 2학기 ‘재미있는 나의 탐구’, 2. 생물과 환경 단원을선정하여 프로그램을 개발하였다. 연구 결과, 맥락중심설계를 적용한 초등과학 프로그램은 학생들의 자기주도적 학습능력 향상에 효과적이었고, 특히 내재적 동기 영역에서 효과가 두드러졌다. 학생들은 과학지식과 관련된 발견의 맥락과 실생활 맥락을 경험하면서, 과학 학습에 능동적으로 참여하고자 하는 욕구가 생겼고, 이것이 적극적인 학습 효과를 이끌어내는 데 필수적인 조건이 되면서 의미 있는 학습이 일어날 수 있는 선순환 고리가 만들어졌을 것으로 판단된다. 본 연구를 통해 도출된 시사점을 바탕으로 다양한영역 및 내용을 대상으로 맥락중심설계를 적용한 프로그램을 개발할 수 있을 것이다 This study aims to develop a class procedure for the application of classrooms that value context and to conduct science classes using this procedure to examine the effects. Among various contexts related to scientific knowledge, the study develops a teaching procedure for designing classes that focus on the contexts of discovery and real life. After verifying the content validity of the context-based design and the program to which it was applied, a class was conducted, and the responses of the children were checked. The final draft of the lesson design completed after revision and supplementation is as follows: context-based design was presented in four stages, namely, presenting, exploring the context, adapting the context, and organizing (share and synthesizing; PEAS). The goal is to enable people to experience the overall flow of scientific knowledge instead of focusing on the acquisition of fragmentary knowledge by covering a wide range of topics from the social and historical contexts in which scientific knowledge was created to its use in real life. To aid in understanding the newly proposed class procedure and verifying its effectiveness, we developed a program by selecting the “My Fun Exploration,” 2. Biology and Environment unit of the second semester of the fifth grade. The result indicated that the elementary science program that applied the context-centered design effectively improved the self-directed learning ability of students. In addition, the effect was especially notable in terms of intrinsic motivation. As the students experienced the contexts of discovery and real life related to scientific knowledge, they developed the desire to actively participate in science learning. As this becomes an essential condition for deriving active learning effects, a virtuous cycle in which meaningful learning can occur has been created. Based on the implications, developing programs that apply context-based design to various areas and contents will be possible.

정숙진,진계환,Jung, Sook Jin,Jin, Gye Hwan The Korean Society of Radiology 2018 한국방사선학회 논문지 Vol.12 No.1
본 논문에서는 OSL 도트 선량계의 교정인자, 흡수선량 선형성, 피크전압 선형성, 각도 변화에 의한 흡수선량 변화를 측정하고 분석했다. 의료용 X 선발생 장치를 사용하여 조사에 노출 선량 보정 계수, 흡수선량 선형성, 피크 전압 선형성은 모두 IEC-62387-1 (2007) 기준을 만족하였다. 기준 방사선 노출과 관련하여 0도, 30도 및 60도에서 선량계 방향에 대한 기준은 -29 % (${\pm}30^{\circ}$) 및 + 67 % (${\pm}60^{\circ}$)이었다. 30도에서 측정된 값은 기준보다 -8 % 낮고 60도에서 기준보다 -18 % 낮게 나타났다. 그러므로 OSL 도트 선량계 사용 시 방향에 따른 영향을 보정하여야 한다. In this paper, we measured and analyzed the dose correction factor, absorbed dose linearity, peak voltage X-ray response, angular dependence. Exposure dose correction factor, absorbed dose linearity, and peak voltage linearity using the medical X-ray generator were all in accordance with IEC-62387-1 (2007). The reference to the dosimetry direction at 0, 30, and 60 degrees relative to baseline radiation exposure was -29% (${\pm}30^{\circ}$) and + 67% (${\pm}60^{\circ}$). The values measured at $30^{\circ}$ were -8% lower than the standard and -18% lower than the standard at $60^{\circ}$. Therefore, the effect of direction should be corrected when using OSL dot dosimeter.

2015 개정 과학과 교육과정에 따른 초등 5, 6학년 과학 검정교과서 생명 영역의 탐구활동 분석
정숙진,신영준 한국생물교육학회 2023 생물교육 Vol.51 No.1
In order to ensure teachers and students' right to choose, such as supporting diverse and creative curriculum autonomy and improving quality through competition, elementary science textbooks have been converted into authorized textbooks and operated from the 2022 school year. In 2022, it was applied to 3rd and 4th graders, and in 2023, it is being applied to 5th and 6th graders. Accordingly, this study attempted to obtain implications by comparing and analyzing the types of inquiry activities in the national textbooks and the newly developed 5th and 6th grade elementary science authorized textbooks. Types of inquiry activities were divided into six categories: experimental observation (EO), simulated activity (SA), investigation discussion and presentation (IP), data interpretation (ID), written reading (RW), and expression (EX). The research results are as follows. First, various types of inquiry activities appeared in nine types of authorized textbooks according to the characteristics of inquiry subjects. In other words, even if the subject is the same, different textbooks have different ways to solve it, and various types of inquiry activities are appearing. Second, looking at the inquiry activities of the 5th and 6th graders by grade, the main types of inquiry activities of the 5th graders were investigation, discussion and presentation (IP), and the 6th graders were experimental observation (EO). It can be seen that the type of inquiry activity focused on inducing students' participation in learning is intensively presented by reflecting the direction of revision of the curriculum to promote student participation-type classes. Third, looking at the types of inquiry activities in detail, experimental observation (EO) and simulated activities (SA) were the main types of inquiry activities with a rate of about 57.3%, and writing and reading (RW) types showed the lowest rate at about 1.5%. The proportion of simulated activities (SA) was 24.8%, which increased about 5 times compared to 3rd and 4th graders. It can be seen that there are many topics that need to be used. The type of reading and writing (RW) presented at the lowest rate can help increase understanding of scientific concepts and improve scientific thinking, so it is hoped that it will be tried in more diverse areas and topics in the next test textbook. As a result, the newly developed and planned 5th and 6th grade elementary science textbooks in the field of life reflect well the purpose of the 2015 revised science curriculum, and were developed based on the existing curriculum, but each publisher conducts various inquiry activities on the same subject. It can be seen that they are trying to secure autonomy and diversity in the curriculum.

In order to elucidate the fraction of sulfoxidation in the over all in vivo metabolism of chlorpromazine (CPZ), the sulfoxidation of CPZ to chlorpromazine sulfoxide (CPZSO) was studied in rats. CPZ (10 ㎎/㎏) and CPZSO (1 ㎎/㎏) were injected into the rat femoral vein. respectively. Md the pharmacokinetic parameters were obtained from the plasma concentration-time pro5les of CPZ and CPZSO determined by the simultaneous analysis using high-performance liquid chromatography. It was supposed that these drugs were almost metabolized in vivo because the total excreted amounts of CPZ and CPZSO via urinary and biliary route were lower than 1.4% and 10.61% of the administered dose, respectively. And also. it was found that the fraction of systemic clearance of CPZ which formed CPZSO (F_(mi)) was 0.115. These results showed that CPZ was sulfoxized by 11.5% in rats and the residue would be metabolized via the other mutes.

정숙진,윤성환 대한건축학회지회연합회 2015 대한건축학회연합논문집 Vol.17 No.6
경제성장에 따른 대도시의 인구집중으로 공동주택 수요가 급증하게되며, 고밀·고층화 추세를 보이게된다. 이로 인하여 열악한 일조환경 및 인공피복율의 증대로 도시 미기후는 점차 악화되고 있는 실정이다. 쾌적한 주거환경 및 도시 미기후 개선을 위해서는 공동주택 단지계획시 일조환경 및 옥외열환경을 고려한 설계가 필요하다. 본 연구에서는 공동주택의 설계 프로세스 단계에서 일조환경 및 옥외열환경을 고려한 배치계획을 함으로서 쾌적한 주거환경으로 에너지 절약 및 도시 미기후 개선을 통한 열섬현상 완화 등을 도모할 수 있는 방안을 모색하고자 한다. 공동주택의 배치계획 주요인자인 인동간격 및 배치 방위각 변화에 따라 주거단지의 일조환경 및 옥외열환경을 예측함과 최적의 인동간격 및 배치 방위각을 선별하여 공동주택 주거단지의 초기 설계계획시 기초 자료로 활용하는 것을 연구의 목적으로 한다. 일조환경 결과로 주거동의 인동간격이 증가할수록 일조 미확보율은 감소한다(인동간격 0.8H에서 1.2H). 또한 배치 방위각은 ESE, WSW에서 일조 미확보율이 낮게 분포하고 있다. 열환경 결과에서 첫 번째, 전 건물표면온도 평균치는 인동간격이 증가할수록 높게 나타나고 있으며, 평균치가 약 0.6℃ 정도 차이를 보이고 있다. 배치 방위각 SE, ESE에서 전 건물표면온도가 낮게 분포하고 있다. 두 번째, MRT 평균값은 인동간격이 증가할수록 감소하는 경향을 보이고 있다. 세 번째, 열섬잠재성은 인동간격이 증가할수록 높게 나타나고 있다. 평균치가 1.0℃ 정도 차이를 보이고 있다. 배치 방위각 SE, ESE에서 열섬잠재성 분포가 낮게 나타나고 있다. Economic growths lead to population increases in large cities. This has brought about the growing necessity for apartment housing which has resulted in higher density populations living in high-rise apartment complexes. Therefore, the urban microclimate is aggravated due to the increasing ratio of artificial coverage and substandard daylight availability. It is important for an apartment to get an adequate amount of sunlight and have a pleasant external surface temperature for the comfort of the occupants. To achieve this, sunlight exposure and external surface temperature must be carefully considered when planning an apartment complex. This study conducts a numerical simulation of the role of major factors when planning an apartment building block with regard to sunlight exposure and external surface temperature. The purpose of this study is to provide a basic reference source for the design and planning of apartment complexes. This study selected the orientation of and distance between buildings the buildings, two important factors in apartment block planning, and evaluated their effects on sunlight exposure and external surface temperature of plate-type apartments. For sunlight exposure, we took the measurements of each house in accordance with the ordinances and rules under the Building Act. For external surface temperature, we conducted a 3D surface temperature simulation and derived the surface temperature, the Mean Radiant Temperature(MRT), and Heat Island Potential(HIP) for the entire building. For sunlight exposure, we used the winter solstice as a reference point and found that as the distance between buildings the buildings increased, the sunlight exposure increased. The ESE and WSW orientations correlated with high sunlight exposure. According to the results of thermal environment, first, the average of the whole building surface temperature is shown to be higher as the pitch of building increases. And a difference of approximately 0.6℃ was shown on the average. Low temperature of the whole building surface is distributed in azimuth SE, ESE. Second, it is shown that average MRT tends to decrease as the pitch of building increases. Third, it is shown that heat island potential is higher as the pitch of building increases. A difference is shown to be approximately 1.0℃ on the average. It is shown that the low heat island potential is distributed in azimuth ESE.
