최수지,이제우,송지현 대한소아치과학회 2017 大韓小兒齒科學會誌 Vol.44 No.3

Molar-incisor malformation (MIM) is a recently described dental anomaly characterized by root malformation in permanent first molars accompanied sometimes by abnormal root forms in primary second molars or enamel defects in maxillary central incisors. This report presents three cases of MIM along with a review of previous studies. Three patients exhibited abnormal root forms in the permanent first molars, with varying degrees of deformation. Two of the patients experienced medical events at birth. One of the patients was a monozygotic twin, whose twin sister exhibited normal dentition without any significant abnormalities. The present report also reviews recently reported cases of MIM in literature. In the management of MIM-associated clinical issues, consideration of microscopic features and accompanying characteristics might facilitate early diagnosis and comprehensive treatment planning.

The purpose of this study was to 1) examine the effects of perceived consequence (external motivator), emotional factor (internal motivator), and social factor on word-of-mouth acceptance, 2) investigate the effects of facilitating condition, and habit on continuance intention to use, and 3) examine the relationships between word-of-mouth acceptance and continuance intention to use by modified Triandis model. A total of 559 samples obtained via an online survey service were used to examine the validity, reliability and adequacy of the research model and verify 6 hypotheses on this basis. Among the components of the Triandis model, emotion, perceived consequence, and social factor were found to have significant positive(+) impacts on word-of-mouth acceptance, also habit and word-of-mouth acceptance had significant positive(+) impacts on the Continuance intention to use. On the other hand, facilitating condition did not have significant positive(+) impacts on the Continuance intention to use. This study will be utilized as basic data on the food service industry to understand the information search behaviors of food service consumers via social media, and eventually, to maintain great ties between media/information and these consumers. 본 연구는 외식소비자의 소셜미디어를 통한 정보탐색행동을 이해하기 위해 수정된 Triandis 모델을 적용하였다. 외식소비자의 온라인 구전정보 수용 및 지속적 이용의도의 선행변수를 인지적 요소(외부동기)인 지각된 결과, 사회적 요인, 촉진조건, 습관과 감정적 요소(내부동기)로 구성하여 구전수용과 지속적 이용의도와의 영향관계를 규명하고자 하였다. 실증 연구를 수행하기 위하여 2014년 6월 17일부터 2014년 6월 22일까지 온라인 조사업체를 통한 최종 559부의 표본을 토대로 연구모형의 타당성, 신뢰성, 적합도 등을 검토하여 총 6개의 가설을 검증하였다. 분석 결과, 감정, 지각된 결과, 사회적 요인 순으로 구전수용에 정(+)의 영향을 미치고, 구전수용은 지속적 이용의도에 정(+)의 영향을 미치는 것으로 나타나 외식소비자의 온라인 구전 정보 탐색 활동을 설명하기 위한 Triandis 모델의 적합성을 확인하였다. 그러나 촉진조건은 지속적 이용의도에 유의한 정(+)의 영향을 미치지 않는 결과를 도출하였다. 이러한 결과는 외식소비자가 소셜미디어를 통해 정보를 탐색하는 행동을 이해하고, 나아가 미디어 및 정보와 소비자 간의 관계를 유지하기 위하여 외식산업분야에서 기초적인 자료로 활용될 것으로 사료된다.

화학공장 설비의 안전한 격리 표준 필요성에 대한 연구

최수지,김상길,조규선 산업진흥원 2023 산업진흥연구 Vol.8 No.4

화학설비의 노후화·고도화·복합화 등으로 인해 설비의 점검, 보수 또는 정비 작업 등의 비일상 작업이 증가하고 있으며, PSM 대상 화학제품제조업 사업장에서의 지난 10년간 발생한 1,483건의 사고 중 비일상 작업 중에 발생한 사고가 전체의 56%(932건)를 차지하여 일상 작업보다는 비일상 작업 중에 더 많은 사고가 발생하는 것을 확인할 수 있다. 특히 공장 운전의 경제성 및 효율성을 위하여 공장 전체를 정지시키지 않고 일부 설비를 정지시킨 후 운전 중인 설비와는 격리한 상태로 점검, 보수 또는 정비 작업을 수행하는 경우가 있다. 따라서 첫째, 화학공장의 취급물질, 운전조건, 설비의 위험도 등을 기준으로 격리 표준(Baseline Isolation Standard)을 수립하여 안전한 격리 방안을 선정하여야 한다. 둘째, 현재 국내 법규 및 기준 상에는 구체적인 격리 표준의 필요성을 제시하지 않고 있으므로 격리 표준의 마련을 제도화하는 것이 필요하다. 이러한 기술적·제도적 개선을 통하여 화학공장 설비에서의 화학물질의 누출에 의한 화재·폭발·중독 사고를 예방하여야 한다. Due to the aging, advancement, and complexity of chemical facilities, non-routine work such as facility inspection, repair, or maintenance work is increasing. Of the 1,483 accidents that occurred over the past 10 years at chemical product manufacturing sites subject to PSM, accidents that occurred during non-routine work accounted for 56% (932 Cases) of the total. It can be seen that more accidents occur during non-routine work than during routine work. In particular, in order to improve the economy and efficiency of factory operation, there are cases where some facilities are stopped without stopping the entire factory and then inspection, repair, or maintenance work is performed while isolated from the operating facilities. Therefore, first, a safe isolation method must be selected by establishing an isolation standard (Baseline Isolation Standard) based on the chemicals handled, operating conditions, and risk level of the equipment in the chemical plant. Second, since current domestic laws and standards do not suggest the need for specific quarantine standards, it is necessary to institutionalize the preparation of quarantine standards. Technical and institutional improvements are needed to prevent fires, explosions, and poisoning accidents caused by leaks of chemical substances.

Eye safety 라이다 센서용 황화납 양자점 기반 SWIR photodetector 개발

최수지,권진범,하윤태,정대웅 한국센서학회 2023 센서학회지 Vol.32 No.5

Recently, the demand for lidar systems for autonomous driving is increasing, and research on Shortwave Infrared(SWIR)photodetectors for this purpose is being actively conducted. Most SWIR photodetectors currently being developed are basedon InGaAs, and have the disadvantages of complex processes, high prices, and limitations in research due to monopoly. In addition,current SWIR photodetectors use lasers in the 905 nm wavelength band, which can pass through the pupil and cause damageto the retina. Therefore, it is required to develop a SWIR photodetector using a wavelength band of 1400 nm or more tobe safe for human eyes, and to develop a material that can replace the proprietary InGaAs. PbS QDs are group 4-6 compoundsemiconductors whose absorption wavelength band can be adjusted from 1000 to 2700 nm, and have the advantage of beingsimple to process. Therefore, in this study, PbS QDs having an absorption wavelength peak of 1415 nm were synthesized, anda SWIR photodetector was fabricated using this. In addition, the photodetector's responsivity was improved by applying P3HTand ZnO NPs to improve electron hole mobility. As a result of the experiment, it was confirmed that the synthesized PbS QDshad excellent FWHM characteristics compared to commercial PbS QDs, and it was confirmed that the photodetector had a maximumcurrent change of about 1.6 times.

Gender Politics in Early Cold War North Korea: National Division, Conscription, and Militarized Motherhood from the Late 1940s to 1960s

최수지 이화여자대학교 통일학연구원 2018 Journal of peace and unification Vol.8 No.2

This study delves into how North Korea designed gender relations from the late 1940s to 1960s, particularly focusing on the Cold War context which predominantly played in its state-building processes. Gender agenda in the 1940s was often used as a means to prove the North’s superiority to the Southern counterpart under the Cold War rivalry and national division. While the establishment of conscription during the Korean War institutionally enabled masculine dominance, the pursuit of Cold War modernity remolded North Korean men and women as collective militarized subjects in the postwar era. North Korea moreover indoctrinated militarized motherhood as an ideal femininity in the 1960s, asking women to bear and rear “manly” sons who are willing to volunteer for troops.

한국 스릴러 영화 속 여성 캐릭터의 특성 변화에 대한 연구 -<도어락>과 <왓칭>을 중심으로-

최수지,차승재 한국영상제작기술학회 2019 영상기술연구 Vol.- No.31

한국의 페미니즘 담론은 문화×예술계에 영향을 미쳐 콘텐츠의 변화를 가져왔다. 영화계에서는 여성 주연 영화의 편수가 증가함과 동시에 여성캐릭터가 약진한 것을 알 수 있다. 이 같은 추세에 따라 스릴러 장르에서도 여성이 주요한 역할을 맡는 작품이 다수 등장했다. 이러한 흐름 속에서 연구자는 최근 개봉한 <도어락>과 <왓칭>에 주목했다. 이 두 편의 작품은 여성 주연 스릴러이면서, 이전 남성 스릴러 속 여성 캐릭터를 답습하지 않는다는 것이 공통점이다. 또한, 여성들이 현실에서 일상적으로 느끼는 공포를 다룬다는 유사점도 눈여겨볼만하다. 이를 토대로 본 연구에서는 기존 한국 스릴러 여성캐릭터의 특성을 기준으로 최근 스릴러 여성 캐릭터의 변화된 지점을 분석한다. 기존 스릴러 여성 캐릭터의 중심 특성은 피해자, 사물화, 수동성, 모성성으로 총 4가지를 추출하여 정의하였고, <도어락>과 <왓칭>의 여성 주인공은 이에 탈피한 모습을 보였다. 이렇게 캐릭터의 변화가 나타나게 된 사회적 배경과 의미, 한계점 또한 알아본다. 두 편의 영화는 기획적인 측면에서 볼 때, 최근 사회 트렌드를 반영한 적절한 캐릭터 개발이며, 장르적 관습에 비춰봤을 때에도 새로운 시도이다. 이 연구를 통해 과도기에 놓여있는 스릴러 장르의 여성 캐릭터의 발전 방향과 가능성을 시사하고자 한다. In Korea, the feminist discourse has influenced cultural and artistic worlds, resulting in a change of properties of female characters. Following this trend, researchers have been attracted to the recently released films <Door Lock> and <Watching>. These two films feature female main characters, but as expected, they do not follow the previous male character themes. It is also worth noting that both films dealt with the fears that women face daily. Based on this, this study analyzes the changed perspective of recent female character-based thriller films on the characteristics of existing Korean thrillers with female characters. The main characteristics of the existing female character thrillers were extracted and defined as four types: victim, objectification, passivity, and maternity. However, the main characters of <Door Lock> and <Watching> showed a breakaway perspective.

Objectives : The purpose of this study is to investigate the effect of acupoint and meridian muscle massage given by automatic massage chair. Methods : We recruited 30 patients with back pain who met inclusion criteria. Two weeks were given as a waiting period, and the massage intervention was applied 12 times for 4 weeks. The programmed automatic massage chair was used to provide effective stimulus on acupoints and meridians for 20 minutes. We used Visual analog scale(VAS) and Korean Oswestry Disability Index(KODI) to quantify pain and function. We also recorded patients' all of vital signs and abnormal reactions during the trial to asses to assess safety. Results : Two participants dropped out due to personal reasons and 28 participants completed the clinical trial. We found that the degree of back pain (VAS, KODI) decreased significantly after the trial. As a result, VAS score decreased from $6.44{\pm}0.85$(Visit 2) to $4.59{\pm}1.52$ (Visit 14)(p<0.001), and KODI score was also reduced from $14.79{\pm}5.13$(Visit 14) to $9.04{\pm}4.52$ (Visit 2) (p<0.001). Also, we did not find any adverse effects in this study. Conclusions : We found that the acupoint and meridian muscle massage can effectively decrease back pain. This proves that the massage program designed by Korean medicine can be a good option to patients with back pain. However, further study with controlled design is still needed to verify its effectiveness.
