Rare-earth zirconates, such as lanthanum zirconates and gadolinium zirconates, have been intensively investigated due to their excellent properties of low thermal conductivity as well as chemical stability at high temperature, which can make these materials ones of the most promising candidates for next-generation thermal barrier coating applications. In this study, three compositions, lanthanum/gadolinium zirconates with reduced rare-earth contents from stoichiometric $RE_2Zr_2O_7$ compositions, are fabricated via solid state reaction as well as sintering at $1600^{\circ}C$ for 4 hrs. The phase formation, microstructure, and thermo-physical properties of three oxide ceramics are examined. In particular, each oxide ceramics exhibits composite structures between pyrochlore and fluorite phases. The potential of lanthanum/gadolinium zirconate ceramics for TBC applications is also discussed.

The purpose of this study is to clarify the influence of parents' socio-economic resources on the class consciousness and life satisfaction of unmarried adult children living with their parents. Data from the 2^nd year (1999) and 22^nd year (2019) of the Korean Labor & Income Panel Study (KLIPS) were used. The study included individuals aged under 25-44 who were unmarried, lived with their parents, and had graduated out of final school. From the 2^nd year (1999), data for 491 people were extracted, and from the 22^nd year (2019), data for 978 people were extracted. The information on the fathers and mothers was obtained from the information on the households data, it was responded by the unmarried children. The main results are as follows. First, one of the characteristics of unmarried children living with their parents is that the average age was higher in 2019 than in 1999. Additionally, although they work and have their own income, they live in houses owned by their parents. Their levels of satisfaction with both the living environment and family relationships were high. It was found that the influence of parents' income increased in 2019 compared with 1999 in the class consciousness. As a factor that influences life satisfaction, the employment status of the father has a positive effect on the life satisfaction for men, whereas the employment status of the mother has a positive effect on the life satisfaction for women.

고속도로 정체 기준 속도의 적정성 검토 및 개선 연구

이수진,고은정,장기태,박성호,박재범,윤일수,Lee, Sujin,Ko, Eunjeong,Jang, Kitae,Park, Sungho,Park, Jaebeom,Yun, Ilsoo 한국ITS학회 2020 한국ITS학회논문지 Vol.19 No.5

Much time has passed since Korea's expressway congestion-threshold speed was revised in 2011. In the meantime, various expressway environments have changed owing to improved performance of vehicles, expanded operations of transport competition (i.e., the KTX), and increased speed limits along some expressway sections. In addition, the speed that expressway users expect to travel at is also increasing. Therefore, through a survey, this study investigates expressway users' perceptions of congestion, and reviews the adjustment of the expressway speed congestion threshold by analyzing expressway traffic flow. One result of the survey confirms that the threshold speed expressway users consider to be congestion has slightly increased. Analyzing traffic and speed data through a K-means algorithm found that the threshold speed for congestion is 60 km/h. In addition, assuming the congestion threshold speed increase from 40 km/h to 50 km/h and 60 km/h, frequently congested expressway sections are identified, determining that 50 km/h is appropriate as a congestion threshold for proper expressway mobility management. 2011년에 고속도로 정체 기준 속도가 개정된 후 많은 시간이 경과함에 따라 차량의 성능 개선, 경쟁 관계에 있는 고속열차 운행 확대, 고속도로 일부 구간의 제한속도 상향 등 다양한 고속도로 주행환경 변화가 발생하였고 고속도로 이용자의 이동 신속성에 대한 기대수준 또한 증가하는 추세이다. 따라서 본 연구에서는 설문조사를 통해 고속도로 이용자의 정체에 대한 인식을 조사하고, 고속도로 교통류 분석을 통해 고속도로 정체 기준 속도의 재설정을 검토하고자 한다. 설문조사 결과, 고속도로 이용자들이 인식하는 정체 기준 속도가 다소 높아진 것을 확인하였다. K-means 알고리즘을 통해 교통량 및 속도 자료를 분석한 결과, 서행과 정체의 분류 기준은 60km/h 수준인 것으로 나타났다. 또한 정체 기준 속도를 50km/h와 60km/h로 상향하는 것을 가정하여 고속도로 정체잦은구간을 산정해본 결과, 50km/h가 고속도로 이동성 관리를 위한 정체 기준 속도로 적절한 것으로 판단된다.

『제주계록(濟州啓錄)』 소재 외국 선박의 제주 표도(漂到)와 문정(問情) 기록 검토

이수진 ( Lee Sujin ) 온지학회 2016 溫知論叢 Vol.0 No.49

이 논문은 19세기 제주도의 각종 해난사고를 기록한 『제주계록(濟州啓錄)』을 대상으로 하여 조선후기 제주 연안에 내박(來泊)한 외국 선박의 현황과 외국 표도민들에 대한 제주목의 보고 처리 과정을 알아보았다. 또한 표도민 심문 내용을 담은 문정기(問情記)를 주요 항목별로 나누어 분석해보았다. 『제주계록』에 수록된 문정기는 모두 18편이다. 이중, 외국 선박의 제주표도 사건에 대한 문정기록 15편만을 대상으로 하여 분석해 보았다. 문정기 작성 시, 선택된 표도인의 지식이나 견문 정도에 따라 조금씩 차이가 있지만 심문항목은 대체로 5가지 정도로 나눠볼 수 있다. 첫째, 표도인의 국적과 표도 경위에 대해서 묻는다. 이때 표도인의 국적, 거주지, 출항일, 출항지, 출항목적, 목적지, 경유지, 표류원인 등을 알 수 있다. 둘째, 선박의 상태와 표도인의 피해 정도를 묻는다. 선박과 선적물품, 승선인의 피해여부를 확인할 수 있다. 셋째, 승선인 명단과 공문(公文)·선표(船票)·서신(書信) 확인하고, 넷째, 선적에 실은 물품정보와 물품 주인에 대해 묻는다. 선적 물품의 종류, 모양, 수량, 가격, 사용법, 도량형 등과 물품 주인의 성명, 출신지 관원 정보를 확인할 수 있다. 마지막으로 출신지역의 지리정보와 귀환에 필요한 바람의 방향을 묻는 것으로 심문을 끝마치게 된다. 19세기 작성된 『제주계록』의 문정기록 역시 18세기부터 제도화된 표류 민 대응 지침에서 크게 벗어나지 않아 형식적인 절차라는 인상을 지울 수 없다. 그렇지만 19세기 제주지역에 표도했던 표도민들의 경향을 살피는데 주요한 자료로 이용될 것이다. 앞으로의 연구는 『제주계록』 이외에 『비변사등록(備邊司謄錄)』이나 『통문관지(通文館志)』 등 조선시대 표류사건이 기록된 공적기록까지 함께 검토하여, 문정기록 전반에 대한 비교분석으로 이어져야 할 것이다. In this article, we investigated on the report process of Jeju Mok for the status of foreign ship arrivals near Jeju Island and foreigners in late-Chosun dynasty with the subject of 『Jeju Gyerok』 which recorded a variety of marine accidents in Jeju Island in 19th century. Also, Moonjunggi which consisted of formal interrogations to the foreigners was analyzed by main items to understand their trends. Analyzing 15 Moonjung records on foreign drifters out of 18 Moonjung records in 『Jeju Gyerok』, the items of formal interrogations could be divided by five although it showed some differences on the knowledge and the experiences in the selected foreign drifters. First, the drifters were asked on the nationality and the drifting details. From this process, they could understand the nationality, the place of residence, departure date, departure location, departure purpose, destination, transit locations, reason of drifting, and so on of the drifters. Second, they were asked on the status of the ship and damages of the drifters. It could find out whether they had damages on the ships, loaded goods, and sailors. Third, they checked the list of sailors, tickets, and letters. Fourth, they were asked on the information of the loaded goods and the owners of the goods. This could find out the types, shapes, prices, usage methods, weights and measures of the loaded goods, and the names and personal details of the goods owners. Finally, they were asked on the information for the geography of the original location and direction of the wind to return to the original location. The important matter in the 17th century was how to return the drifters in the drifting cases. There were almost nothing mentioned on the drifting ships or goods. However, with more frequent drifting cases in 18th century, the rules on the drifters were systemized to record a variety of items including the loaded goods, ships, supplied goods, process of the deaths, and so on together with returning the drifters. Moonjung records in 『Jeju Gyerok』 which had been prepared in the 18th century also were not deviated significantly from the rules on the drifters systemized from the 18th century which seemed to be only formal procedure, however, they could be utilized as the main data to investigate the trends of the drifters in Jeju Island in the 19th century. Furthermore, it is necessary to expand the scope not limiting Jeju Island in the 19th century but analyzing the trend of the foreigners who drifted in Chosun.

기능적 행위지배의 ‘계속적 영향력’과 범행단계와의 관계

이수진(Lee Sujin) 한국형사법학회 2016 刑事法硏究 Vol.28 No.2

공동정범이기 위해서는 자기 자신의 범행기여분이 타관여자의 범죄행위 몫을 보충해주고, 동시에 역으로 타인의 범행활동을 자기 자신의 범죄행위 몫을 보완하는데 이용해야 한다. 기여행위의 범죄실현을 위한 비중을 인과적 측면에서 따져봤을 때, 실질적으로 공범과의 차별화가 가능하고 전체범죄에 대한 귀속이 가능한 행위라면 정범성을 부여할 수 있음이 원칙이다. 이러한 기능적 행위지배의 의미에 따르면, 실행단계 이전 기여는 서로에게 의존하는 정도가 실행단계에서의 정도와 다를 수 있고 직접적으로 구성요건 실현을 지향하는 위험성이 존재한다고 평가되는 실행의 착수 이후 단계 기여와는 다른 규범적 평가가 가능하다. 물론 이런 이유만으로 단순히 실행단계의 기여로 공동정범의 범위를 제한하는 것 은 문제가 있지만, 단계별로 그 기여행위의 의미는 달리 이해할 필요는 있다. 이를 위해 필자는 실행단계 이전 가담행위가 갖춰야 할 하한선을 제안하여 기능적 행위지 배의 본질적 기여의 해석을 조금 구체화하고자 하였다. 실행의 착수 이전 단계에서 의 기여는 객관적 판단에서 공범과의 분명한 차이가 부족하여 그 외에 추가적인 차별화가 요구된다. 이를 위해 실행단계에서의 기여행위보다 높은 하한선을 설정하여 구분하는 시도를 하였다. The joint principal offender replenishes other actor’s criminal act with his contribution and the other actor contributes the main crime with the joint principal offender. If we consider the causal importance of individual share, the joint principal offender is different from a complice and belongs all of the crime. This is the feature of co-principal offender. The partial act through preparation stage before the start of execution distincts from the one through practical steps in terms of mutually depenence. The partial act after committing crime has the dangerousness which aims to constituting a crime. So this is not same to partial act through preparation stage before the start of execution. Natually, as the case stands we could not conclude that only partial actor after committing crime can be the joint principal offender. But each partial act must get across differentially. I suggest the lower limit for more detailed interpretation of “essential contribution” at preparation stage before the start of execution. We can’t distinguish clearly between partial act through preparation stage before the start of execution from confederate. So this attempt is meaningful.

젠더인식 기대지평 변화에 따른 소설 읽기 양상 연구

이수진 ( Lee Sujin ) 서울대학교 국어교육과 2022 先淸語文 Vol.50 No.-

This study aims to reveal the characteristics and principles of novel reading according to the change of the reader’s expected horizon, especially focusing on gender awareness. According to Jauß’s receptive aesthetics, experience and evaluation on texts change along the readers’ horizon of expectations as the time goes by. In particular, this study seeks to pay attention to the “gender awareness,” which is an important agenda item in modern society, among other things. By applying Said’s concept of secular criticism, it is suggesting the concept ‘reading novels according to changes in reader’s Gender Awareness-Expectation Horizon’, which explains the reader’s performance of reorganizing the existing order in the text and securing the validity of their interpretation by meditating between the reader’s current horizon and the past horizon in the text. In this process, the content of desirable gender awareness cultivated through novel education was taken as a reflection of the problem of gender representation in novel texts and aiming for a new aesthetic of representation, based on Judith Butler’s gender theory. The component of novel reading education according to changes in expectations are summarized as ‘Overcoming the dichotomy of genre aesthetics and political correctness’, ‘Understanding the relationship between novel’s representation and gender awareness’, and ‘Reassessment of literary history significance through the rereading of blackouts’ and these characteristics are realized through the reading of learning readers at the classroom site. Based on these theoretical discussion, the following reading principles were established from the interpretive texts of professional readers. : ⅰ) the perception of discomfort with tests ⅱ) the distance adjustment through the reconstruction of text ⅲ) the convergence of horizon through re-meaning of text. Based on principles, it was confirmed that ‘reading novels according to changes in readers’ horizon of expectations’ was found at a lower level than that of professional readers, but also found in learning readers’ reading patterns. This study is meaningful in that it suggests the possibility of the readers’ horizon of expectations, particularly focusing on gender awareness which is a recent social agenda, as a meaningful resource for interpretation in literary education. It is also meaningful in that the learning readers played a role in the composition of literary history through the dialogues between the learning readers and discourse of preceding interpretations. In addition, when considering the various horizon of expectations conflicted in the modern society, the learning readers do not easily exclude other people’s opinions or show a negative and violent attitude toward others, and have a logical and ethical opinion through the experience of validating the interpretation of the novel.

인터넷 쇼핑몰 상에서의 상품 추천 시스템은 전자 상거래가 시작된 이래로 중요한 연구 주제 중 하나이다. 인터넷 서점에서 제공되는 추천 서비스는 특정 책을 구매(보관)한 사람이 구매(보관)한 또 다른 책을 주로 추천하는 형식이다. 그러나 이러한 책의 추천 방식은 상품추천에 있어서 개별 사용자의 취향을 고려하기 어렵다는 한계점을 안고 있다. 이 연구에서는 인터넷 서점 이용자들을 대상으로 독서에 대한 니즈, 독서 스타일, 선호 장르에 따라 독서유형을 분류하였다. 그리고 각 유형 별 인터넷 서점에서의 정보탐색 및 책 구매 고려 요인의 특성을 탐색하였다. 마지막으로 추천 서비스에서 독서유형의 활용 가능성을 모색하였다. Recommender service of online bookstore is the important issue in E-commerce filed. Online book store offers a specific book to a user indicating that people that buy this book also purchase 'X' book. Although this type of recommender service is popular, it is not considered for each individual taste. The research has performed to explore the reader's type, important factor for purchasing and information behavior. According to that, recommender service on the basis of reader's style is suggested.
