손혜진,김창락 한국방사성폐기물학회 2024 방사성폐기물학회지 Vol.22 No.1

Safe radiation management is essential not only for operational nuclear power plants but also for nuclear plants to be decommissioned. When spent nuclear fuel is present on-site, meticulous radiation emergency plans are necessary to ensure safety. In Korea, numerous radiation emergency plans have been established for operational nuclear reactors. These plans delineate distinct response mitigation measures for white, blue, and red emergencies. However, clear regulations are yet to be devised for radiation emergency plans for reactors to be decommission. Therefore, this study investigated the decommissioning plan and status of Kori unit 1 to comprehensively analyze the current status of decommissioning safety in Korea. In this study, radiation emergency plans of decommissioning nuclear power plants abroad were reviewed to confirm radiation emergency action levels. Furthermore, radioactive waste treatment facilities, to be used for decommissioning reactors in Korea were evaluated. Moreover, the study assessed emergency plans (especially, emergency initiating conditions) for operational nuclear power plants in Korea for potential use in the decommissioning phase. This study proposed an emergency initiating condition that can be used for decommissioning reactors in Korea. Considering the anticipated introduction of plasma torch melting facility in Korea, this study examined the conditions of radiation emergency plans can be altered. This study identified effective measures and guidelines for managing radiological emergency initiating conditions, and effective decommissioning of nuclear power plants in Korea.

손혜진,전귀연 대한가정학회 2003 Family and Environment Research Vol.41 No.2

The purpose of this study is to investigate how much individual. relational, and contextual variables have an effect on the dating violence of premarital males and females. Researched are 369 male and female residents over 19 years have experienced dating or were involved in any dating relationships in Daegu.

사회문화이론적 관점에서 본 한국어 학습자의 L1 사용 연구

손혜진 국제한국어교육학회 2019 한국어 교육 Vol.30 No.3

The purpose of this study is to reveal the relationship between learner’s use of L1 and Korean language learning, and to derive educational implications of learner’s use of L1. To do this, this study examines Chinese learners’ learner-learner dialogues which were produced while they participated in role-play tasks, and analyzed the L1 use of learners included in the dialogues. As a result, in the case of this study, when learners construct the content of role-playing, they use their L1 to check if it is appropriate according to the instructions of the task, to discuss different opinions, and to communicate their opinions more accurately. In addition, learners used their L1 for the purpose of choosing the more appropriate Korean expression which is to be used in the role play and supplementing the lack of Korean knowledge of peer learners. Finally, learners used L1 to understand the task itself in order to carry out the task successfully. Thus, in this study, it was confirmed that L1 is used as a support tool for L2 learners to accomplish more successfully the task of role-playing, which is communicative task in Korean language learning. In the communicative language classroom, it is almost impossible not to control learner’s L1 use at all. However, since L1 use can support the accomplishment of the L2 task, it is necessary for the Korean language learner to use it partially considering the specific learning objectives set in the individual classroom and the characteristics of the learner.

유치원 만 5세 학급에서 증강현실과 가상현실을 활용한 놀이에 대한 사례 연구

손혜진,엄정애 이화여자대학교 이화어린이연구원 2022 영유아교육: 이론과 실천 Vol.7 No.1

본 연구는 증강현실과 가상현실을 활용하는 어플리케이션을 놀이 도구로 사용할 때 나타 나는 유아의 놀이 경험을 통해 놀이 중심 교육과정에서 디지털 기술을 사용하는 방안에 대 한 이해를 제공하고자 하였다. 이를 위해 코스페이시스(CoSpaces)와 구글 아트 앤 컬쳐 (Google Arts & Culture) 어플리케이션을 선정하여 서울의 S유치원 만 5세 2개 학급 유 아 34명을 대상으로 약 12주간 관찰을 진행하였다. 연구를 통해 살펴본 유아의 놀이 경험 은 디지털 매체 활용에 대해 도전해보기, 현실적으로 불가능한 상황을 경험하며 즐거움 느 끼기, 가상과 현실의 융합을 통해 놀이 공간이 확장된 놀이하기, 관계에 있어 새로운 기회 를 제공하는 놀이하기로 범주화 할 수 있었다. 유아들은 증강현실과 가상현실을 사용하기 위해 새로운 디지털 매체를 사용하는 과정에 몰입하고, 실패를 경험하면서도 도전하는 과 정에서 성취감을 느끼는 모습을 보였다. 유아들은 가상의 세계에서 현실에서는 불가능한 것을 경험하고, 탐험하며 즐거움을 느끼는 모습을 보였다. 현실과 융합된 가상의 놀이 공간 은 유아의 상상놀이를 자극하고 공간적으로 확장된 놀이를 제공하였다. 마지막으로 디지털 기술의 개방성은 유아의 또래관계에도 영향을 미쳐 더 다양한 또래와 상호작용할 기회를 제공하였고, 유아가 현실에서보다 더 많은 것을 성취할 기회를 제공하여 유아 스스로, 혹은 다른 또래가 유아에게 가지고 있는 이미지에 영향을 미치는 것으로 나타났다.

다문화 청소년 내담자의 ‘학교 적응 경험’에 대한 현상학적 연구

손혜진 한국다문화교육학회 2020 다문화교육연구 Vol.13 No.3

The purpose of this study is to understand the school adjustment experiences of multicultural adolescent clients who had received counseling at their school counseling office. The clients were interviewed in-depth about their school adjustment experiences. Then, the interviews were analyzed by using the phenomenological method to determine the school adjustment experiences of the clients and the meaning that these experiences have for them. The study found that on the basis of a total of 108 meanings, there were 54 themes, 12 themes clusters, and four categories that formed the essential structure of school adjustment experiences. Thus, it was revealed that the school adjustment experiences reported by the multicultural adolescent clients can be essentially classified into four phenomenological categories of meaning. These four categories are “Living as the invisible in class.”, “You’re the Etc.”, “The time of storm and stress: confronting in agony, distress, and isolation”, “Adapt to the state of maladjustment.” Based on these findings, the study suggested the significance and limitations of multicultural education and school counseling with respect to improving the school adjustment of multicultural adolescent clients. 본 연구는 다문화 청소년 내담자의 학교 적응 경험의 본질과 의미를 이해하는 데 목적이 있다. 이러한 연구목적을 위해 학교 상담실에 방문하여 상담을 받은 경험이 있는 10명의 다문화 청소년 내담자들에게 학교 적응 경험을 묻는 심층 면담을 하고 현상학적 방법으로 분석 절차를 거쳐 다문화 청소년 내담자의 학교 적응 경험과 의미는 무엇인지 알아보았다. 연구 결과 총 108개의 의미를 기반으로 하여 경험의 본질적인 구조인 54개의 주제와 12개의 주제 묶음, 4개의 범주를 도출하였다. 연구 결과 나타난 다문화 청소년 내담자의 학교 적응 경험의 본질은 ‘다수의 부정적 경험의 반복과 소수의 긍정적 경험 사이의 위태로운 외줄타기’이다. 이를 구체적으로 살펴보면 중도입국 다문화 청소년들은 첫째, ‘교실의 투명인간’이 된 것 같은 경험을 했다. 둘째, 자신에 대해 “너는 ‘기타 등등’이야.”라고 말하는 듯한, 자신에 향한 경계와 편견, 미묘한 차별과 은밀한 배제를 알아차리는 경험을 했다. 셋째, 질풍노도의 시기라는 발달적 특수성과 이들이 마주한 상황적 특수성이 맞물리며 ‘고민과 고통, 고립을 마주하는’ 경험을 했다. 넷째, 이러한 과정 속에서 이들은 ‘부적응에 적응하는’ 경험을 했다. 이와 같은 결과를 바탕으로 다문화 청소년 내담자의 학교 적응력 향상을 위한 다문화 교육과 학교 상담의 의의 및 제한점을 제시하였다.

Long Term Trend of Uranium Production and Price

손혜진,강수현,정종필,김창락 한국방사성폐기물학회 2023 방사성폐기물학회지 Vol.21 No.2

To broaden the utilization of nuclear energy, uranium as a fuel should be mined indispensably. Mining accounts for the largest portion of the cost of producing the uranium assembly. Therefore, this study analyzes the trends of uranium prices, which have a significant impacts on the mining cost. Uranium production contributing to the price fluctuations is explained in five periods from 1945 to the present. Moreover, the series of events affecting uranium prices from the 1970s until the present are verified. Among them, the most recent incidents considered in this study are the following: COVID-19 pandemic, Kazakhstan unrest, and Russia-Ukraine war. European countries have started to reconsider the transition to nuclear power to reduce their dependence on Russian oil and gas, which has contributed to the surge in uranium prices. Based on the results of this study, various international issues have been closely associated with the nuclear power industry and uranium, affecting the production of uranium and its price.
