신서영,채용권,이고은,김미선,남옥형,이효설,최성철 대한소아치과학회 2024 大韓小兒齒科學會誌 Vol.51 No.1

This study aimed to assess the accuracy of tooth widths, intermolar widths, and arch lengths acquired through two intraoral scanners, including iTero Element Plus Series (Align Technology, Santa Clara, CA, USA) and Trios 4 (3Shape, Copenhagen, Denmark), specifically on mixed dentition. A total of 30 subjects were divided into 2 groups, each undergoing both alginate impressions and intraoral scanning using either the iTero or Trios scanner. The plaster models were measured with a caliper, while the digital models were measured virtually. In the iTero group, all tooth width measurements exhibited differences compared to the plaster values, except for maxillary left lateral incisors (p = 0.179), mandibular right (p = 0.285), and left (p = 0.073) central incisors. The Trios group did not display significant differences in any of the tooth width measurements. Intermolar width comparisons for both groups indicated differences, except for mandibular primary canine to primary canine values (p = 0.426) in the iTero group. Regarding arch length, the mandibular anterior, maxillary right, and left arch lengths in the iTero group demonstrated larger caliper values than those of iTero. Conversely, in the Trios group, all parameters showed smaller caliper values, especially in upper anterior, maxillary right, mandibular right, and mandibular left arch lengths with significance (p = 0.027, 0.007, 0.003, and 0.047, respectively). Despite the differences between the two groups, digital models might be clinically suitable alternatives for plaster models. Pediatric dentists should carefully assess these differences, as a comprehensive evaluation would result in precise orthodontic treatment planning and favorable outcomes for young patients with mixed dentition.

요코미쓰 리이치의 시계 론 – ‘고무회사’와 ‘독일낭만파’ 음악의 표상 –

신서영 한국외국어대학교 일본연구소 2022 日本硏究 Vol.- No.93

This study examined the symbolic meaning of rubber companies and German romantic music, noting that the “Clock” serialized in Fujinnotomo in 1934. Yokomitsu induced the reader’s participation through descriptions related to the fourth person(self- consciousness), coincidence of “Pure Novel Theory” about Utsu, a point-of-view character who does not know the inner stories surrounding the characters of the rubber companies. In addition to the merger of a rubber companies, Mine showed a symbolic image of expanding Japanese household system by marrying Akiko, who was not bound by the Japanese household system. Yokomitsu presented German romantic music, imprinting on the reader that the Japanese military cooperated with Germany to maintain sovereignty over the South Seas, a rubber supplier after Japan withdrew from the League of Nations, and at the same time tried to realize the world of possibility symbolized by ‘pure sound’ of Utsu.  Yokomitsu introduced a method that allows readers to understand for themselves the fact that the merger of rubber companies, the problems of political marriage, and German romantic music, which were revealed through the children of four families who ran a rubber companies, were intertwined with the political situation of the time. Yokomitsu warns of a dark catastrophe in which Japan is trying to apply its household system overseas as well, creating a world of automobiles rather than cavalry.

Nanostructure via Solvent Vapor Annealing of Conjugated Polymer Thin Films to Improve Volatile Organic Compound Sensing Performance

신서영,장민철 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.2

We demonstrate that pre-formed nanostructures (PNs) facilitate the self-assembly of polymer chains into longer, one-dimensional (1-D) nanostructures in poly(3-hexylthiophene) (P3HT) thin films during solvent vapor annealing (SVA). Consequently, a SVA with chlorobenzene (CB) significantly enhanced the charge-carrier mobility of the OFET devices based on PN1-P3HT films deposited from a sonicated solution and PN2-P3HT films deposited from an UV-irradiated solution. The surface area of the two films also significantly increased. After performing the SVA, highly improved sensitivities for detecting volatile organic compounds (VOCs) were observed for the OFET sensors, this can be attributed to the improved charge transport and surface-to-volume ratio of the films. In particular, the PN2-P3HT OFET sensors exhibited excellent responsivities and response/recovery times in the detection of the VOCs used: methanol (62.4%, 126s/130s), ethanol (41.5%, 134s/151s), toluene (33.2%, 89s/144s).

신서영 한국국제교육교류학회 2021 국제교류와 융합교육 Vol.1 No.2

본 연구는 국정도서로 개발되는 특수교육 기본교육과정 교과서의 질 관리를 위해 특수교사를 대상으로 교과서 사용 단계의 평가 체제 구축과 관련한 인식을 조사하고, 그 결과를 바탕으로 교과서 평가 체제 구축 방안을 제안한 것이다. 연구를 위하여 우선 국정도서의 질 관리 체제를 개발 단계와 사용 단계로 나누어 살펴본 다음, 사용 단계의 질 관리 체제로서 사용 단계 평가 체제의 필요성을 제기하였다. 다음으로 사용 단계의 평가 체제 구축 방안을 모색하기 위해서 전국의 특수교사를 대상으로 모바일 메신저를 통해 평가체제 구축과 관련한 설문을 배포하고 그 중 설문에 참여한 159명의 응답을 분석하였다. 분석 결과, 기본교육과정 교과서를 사용하고 있는 특수교사의 교과서에 대한 만족도는 평균 3.3점이었으며, 사용 단계의 교과서 평가가 필요하다는 인식은 평균 4.02로 만족도보다 높았다. 사용 단계 평가 체제의 구축 방안에 있어서, 평가의 주체는 교사(98.7%), 독립된 플렛폼 구축(62.2%), 정기평가(49.4%), 척도형 문항과 개방형 문항을 혼합한 문항(50.6%)을 선호하였다. 또 평가 결과는 ‘사용자로 인증된 사람에게만 공개(55.1%)’, 평가 결과 반영 시기는 ‘차기 교과서 개발 시’가 가장 많았다(41.0%). 연구결과를 바탕으로 특수교육 기본교육과정 교과서의 사용 단계 평가 체제 구축을 위해서는 독립적인 평가 플렛폼을 구축하되, ‘교과서 사용성’을 규명하여 간단하고 명료한 질문을 통해 교과서 사용자 모두가 부담없이 평가할 수 있도록 하고, 질관리위원회 조직을 통해 평가 결과의 수정반영 여부를 심의할 것을 제안하였다. 또, 평가 플렛폼에 이미 개발된 교과서와 사용자인 교사가 제작한 다양한 콘텐츠를 탑재할 수 있도록 하여 개발-사용-평가 통합형 플렛폼을 운영할 것을 제안하였다. This study investigated the perception of special teachers regarding the establishment of an evaluation system in the textbook use stage to manage the quality of textbooks developed as government-run books, and proposed a plan to establish a textbook evaluation system based on the results. For research, the quality management system was examined as a development stage and a use stage. And then, the necessity of a use stage evaluation system was raised as a quality management system for the use stage. Next, in order to find a way to establish an evaluation system in the use stage, the survey responses of 159 special teachers nationwide were analyzed. As a result of the analysis, the average satisfaction with textbooks of special teachers using basic curriculum textbooks was 3.3 points, and the perception that textbook evaluation at the stage of use was 4.02 was higher than the satisfaction. In the method of establishing a use-stage evaluation system, teachers (98.7%), independent platform construction (62.2%), regular evaluation (49.4%), and questions (50.6%) mixed with scale questions and open questions were preferred. In addition, the evaluation results were "disclosed only to those certified as users (55.1%), and the timing of reflecting the evaluation results was "when developing the next textbook" (41.0%). Based on the research results, it was suggested to establish an independent evaluation platform to establish a system for evaluating the use of basic curriculum textbooks, but to identify "textbook usability" so that all textbook users can evaluate it without burden and to review the revision of evaluation results through the Quality Management Committee organization. In addition, it was proposed to operate an integrated development-use-evaluation platform by allowing the evaluation platform to be equipped with textbooks already developed and various contents produced by teachers who are users.

『家族会議』における株の意味 -純粋小説としての経済小説-

辛西永 한국일본언어문화학회 2023 일본언어문화 Vol.65 No.-

This study focused on the fact that “Family Meeting” is an economic novel as a ‘pure novel’ and examined the meaning of stocks depicted in “Family Meeting”. The “Family Meeting” tells the story of a brokerage firm in Kabutocho, Tokyo, which suffered heavy losses from the collapse of the Japanese financial markets due to the European War, the Great Kanto Earthquake of 1923, and the Great Depression, being attacked by broker Nire from Osaka in the relationship between Takayuki and Taiko. The ‘pure novel’ discussed in ‘pure novel theory’ creates a possible world by reconstructing reality rather than depicting society as it is. This study analyzed description of Takayuki’s stock brokerage collapse and Nire’s stock price problem by comparing it to contemporary reality, and examined the differences and commonalities between reality pursued by Yokomitsu and reality as a social criticism aimed at by proletarian literature. In addition, this study clarified that Yokomitsu did not reveal the actual events as they are in “Family Meeting” and drew the absurdity of the Japanese financial system, and furthermore, “money” itself through the love story of the two young people, and that Yokomitsu wanted to convey to the reader that the economic damage revealed in the “Family Meeting”, especially the fall of the middle class, was the decisive cause of shaking the living base, housing, and traditional values and entering an era of anxiety.

광고디자인의 비주얼 표현요소로서 수묵의 조형적 특성 연구

신서영 한국정보디자인학회 2009 정보디자인학연구 Vol.12 No.1

21세기 산업의 디자인 영역은 무한정 확장되고 새로운 가능성을 제시 한다. 여기에 컴퓨터가 보급되면서 현대인들은 기계적이고 획일적인 느낌의 시각 환경에 살고 있다. 이 시점에서 우리가 가장 보강하고 되짚어 볼 문제는 ‘전통성’과 ‘독창성’으로서 수묵의 가치와 함께 우리 고유의 것을 발전시켜 우리의 가치를 찾고자 하는 시대적 필요성에 이르렀다. 본 연구는 광고디자인의 수묵적 표현의 조형적 특성을 알아보기 위하여 OTTO사이트의 2007년부터 2009년까지의 TV광고 중 수묵적 표현으로 제작된 광고를 선정하였다. 선정된 광고의 사례분석을 통하여 수묵에 대한 새로운 시각이미지를 재정립하고 컨셉에 맞는 다른 시각요소들과 조화로운 독창적 형태의 디자인으로 수묵적용에 대한 문제점을 찾아 광고디자인의 다양성과 가능성을 제시하고, 수묵적용의 문제점을 찾아보고 그 개선방안을 모색하고자 한다. 또한 수묵의 특특한 표현이 광고디자이너에게 새로운 시도를 창출할 수 있는 또 다른 문화적 시도가 될 것임을 강조하고자 한다.
