판타지 영화에서 나타나는 이차 세계의 유형 분류

최유민,이준희 한국영상학회 2014 한국영상학회 논문집 Vol.12 No.3

본 논문은 판타지 영화 장르에서 나타나는 현실에 존재하지 않는 세계, 즉 이차 세계를 공간의 특징별로 분류하였다. 이차 세계는 톨킨이 제시한 개념으로서, 현실 세계인 일차 세계와는 전혀 다른 논리로 이루어진 환상의 세계이다. 본 논문에서는 이차세계를 분류하는 기준을 “이차 세계의 형태”와 “일차 세계와의 관계”로 세우고 이를 기준으로 다섯 가지 유형으로 도출하며 도식화 하였다. 견고하게 구축된 이차 세계는 다양한 플랫폼을 통해 이야기가 확장되는 트랜스미디어 콘텐츠로서의 가능성이 무궁무진하다. 하지만 제작에 앞서 서로 다른 매체의 제작자들이 세계관에 대한 이해가 선행 되어야 할 것이다. 세계관 공정 과정에 기본이 되는 이 연구를 토대로 세계관 정의에 대한 연구가 진행 될 수 있으며, 공동 창작으로 변화하는 제작 과정에 의미 있는 연구라고 할 수 있다. This research looks to classify the secondary world, a imaginary world created in the narrative of fantasy fiction genre, in relation to the primary world, the real world mirrored the same logic and feel. First, we discuss the historical and theoretical aspects of the world. Based on the discussion, we laid out the relational diagrams between the first and secondary world. A story can have possibilities to be expand as a trans-media contents. For it to take place, a solid structure of a secondary world has to be designed so that the expansion does not hinder the original story. This research aims to help further research by providing a solid base on how the worlds exist in fantasy genre.

최유민 한약정보연구회 2021 한약정보연구회지 Vol.9 No.2

This study is a pilot systematic review on the effectiveness and safety of acupuncture for menstrual headaches. Finally, seven documents were included and analyzed according to the protocol. When comparing the treatment effect with total effectiveness as an outcome variable, we found that acupuncture treatment has a therapeutic benefit compared to Western medicine treatment. In addition, there were no reports of adverse events caused by acupuncture treatment. However, it is difficult to conclude the effectiveness of acupuncture treatment due to the small sample size and a sufficient risk of bias in the included studies.

최유민,김선미,최남기 대한소아치과학회 2020 大韓小兒齒科學會誌 Vol.47 No.1

The purpose of this study is to evaluate the morphological characteristics of the roots and roots canals of primary molar teeth using Cone-Beam Computed Tomography (CBCT). A total of 68 CBCT images of children aged 4 - 5 years was used for this study. A total of 160 molar teeth were analyzed. Various parameters such as the number of roots and canals, length of root and root canal, and the angulation and shape of the roots were analyzed. All maxillary primary molars had 3 roots. The presence of 2 root canals in 1 root was only observed in the mesiobuccal root of maxillary primary second molars. Most mandibular primary molars had 2 roots, and most mesial roots had 2 root canals. Concerning the length of the roots, the palatal root of the maxillary primary molar was found to be longest whereas the distobuccal root was shortest. In mandibular primary molars, the mesial root was longer than the distal root. In maxillary primary molars, the palatal root had the greatest angulation whereas the distal root has the greatest in mandibular molars. The root and root canals of maxillary primary molars were more curved in shape whereas mandibular primary molars were straight. 이 연구의 목적은 CBCT를 사용하여 유구치 치근 및 근관의 형태학적 특징을 평가하는 것이다. 과잉치 발거를 위해 전남대학교 치과병원 소아치과에 내원하여 CBCT를 촬영한 만 4 - 5세 환자 총 68명의 영상으로 연구를 진행하였다. 치근 흡수가 되지 않은 상악 제1유구치, 상악 제2유구치, 하악 제1유구치, 하악 제2유구치로 구분하여 분석하였다. 치근 및 근관의 수, 치근 및 근관의 길이와 각도 등의 다양한 변수들이 분석되었다. 상악 유구치는 모두 3개의 치근을 가졌고 원심 협측 치근과 구개 치근은 단일 근관을 가졌다. 한 치근에 2개의 근관이 있는 경우는오직 상악 제2유구치의 근심 협측 치근에서 발견되었다. 하악 유구치는 대부분 근심과 원심 2개의 치근을 가졌다. 하악의 근심 치근은대부분 2개의 근관을 가졌다. 치근의 길이와 관련하여, 상악의 구개 치근의 길이가 가장 긴 반면, 원심 협측 치근의 길이는 가장 짧은 것으로 밝혀졌다. 하악 유구치는 근심의 치근이 더 길었다. 상악 유구치에서는 구개 치근의 각도가 가장 컸으나 하악은 근심의 각도가 더 작았다. 상악 유구치의치근 및 근관이 곡선형이 많은 반면 하악 유구치는 직선형을 더 많이 볼 수 있었다.

Objectives : The purpose of this study is to investigate various application methods of focused ultrasound and apply them to clinical use in Korean medicine. Methods : Search was performed using the search engines of electronic databases, including PubMed, ScienceDirect, Cumulative Index to Nursing and Allied Health Literature (CINAHL), ScienceON, Oriental Medicine Advanced Searching Integrated System (OASIS), China National Knowledge Infrastructure (CNKI), Wanfang Data, Japan Science Technology Information Aggregator, Electronic (J-STAGE) and Citation Information by NII (CiNii), from inception to July 2023 without language limitation. Inclusion criteria were clinical studies including randomized controlled trials (RCTs), and animal experimental studies related with focused ultrasound treatments for acupoints or meridian sinews. Results : Total 17 papers, 7 for RCT, 6 for in vivo animal studies, and other experimental studies, were finally selected. Indications used in studies were shoulder pain, back pain, chronic back pain, and degenerative knee arthritis. In experimental studies, studies on animal models of hypoxic ischemic brain damage and hyperlipidemia were also conducted. As for the acupoints, LR3, LI4, and ST36 were used in clinical studies and, in animal experimental studies, GV20, KI1, and ST36 were used. As for the dose, 4 studies below 3 W/cm2 and 3 studies in the range of 0.625 to 5 W/cm2 in clinical studies, and all studies did not exceed 5 W/cm2. In animal experimental studies, 0.5 W/cm2, 2 W/cm2, 7.5 WW/cm2, 15 W/cm2, 10∼20 W/cm2 were used. In all three studies describing the penetration depth during irradiation, it was less than 1 cm. Conclusions : We suggest that focused ultrasound is an appropriate treatment tool for stimulating the acupoints to transfer heat energy. Future studies with rigorous and well-designed RCTs for various diseases will be required to ascertain the focused ultrasound stimulate acupoints or meridian sinews.

Objectives : The purpose of this study was to review the effectiveness of acupuncture and moxibustion therapy for the treatment of acute herpes zoster. Methods : Data was collected by two researchers. Clinical trials on PubMed were retrieved using MeSH terms including “herpes zoster” combined with “acupuncture therapy”, “moxibustion”, “bloodletting”, “electroacupuncture”, and related keywords. We excluded irrelevant studies and included randomized and non-randomized controlled trials, case series and case reports. Finally, we selected a total of thirteen studies and conducted a literature analysis and an object quality assessment. Results : Twelve of thirteen studies were about acupuncture and moxibustion combined therapy. Only one study suggested that a single acupuncture therapy is expected to be equally as effective as a common western medicine therapy. There was some evidence related to the effectiveness of moxibustion, venesection and electroacupuncture, but it dealt with combining therapy and was insufficient, and with an inclusion of potential risk factors. Only one study was conducted under approval from an institutional review board. No severe treatment-related adverse events were observed. A quality assessment suggested that there was some weakness in the areas of blinding and concealment. Conclusions : There is some evidence that suggests the effectiveness and safety of acupuncture and moxibustion combined therapy as a treatment for acute herpes zoster.

최유민,김종욱,김락형,육태한 대한침구의학회 2017 대한침구의학회지 Vol.31 No.3

Objectives : The purpose of this study was to determine the electrical properties of the buccal area using facial surface electromyography (sEMG). Methods : This research was conducted on 44 healthy participants irrespective of their sex. Surface electrodes were attached to the midpoints of three imaginary lines connecting ST4 (Dicang) to ST6 (Jiache), ST4 to SI18 (Quanliao), and ST4 to the center point of SI18 and ST6. Then, the participants were trained in the movement that included a comprehensive action of buccal area. While the participants were performing the motion, sEMG values (E1, E2, E3) and the distance change of the three imaginary lines (D1, D2, D3) were measured. The data were statistically analyzed using SPSS ver. 22.0. Results : Significant differences were observed in the distance changes (D1>D3, D2>D3) and sEMG values (E1<E2<E3). Moreover, there were positive correlations between D1 and E1, D2 and E2. Conclusion : We suggest that the measurement at ST4 to the center point of ST6 and SI18 with this motion would be adequate to check the electrical characteristics of the buccal area.

최유민,정다정,김석희,김종욱,육태한 대한약침학회 2015 Journal of pharmacopuncture Vol.18 No.1

Objectives: Water-soluble carthami flos (WCF) is a new mixture of Carthami flos (CF) pharmacopuncture. We conducted a 4-week toxicity test of repeated intramuscular injections of WCF in Sprague-Dawley rats. Methods: Forty male and 40 female rats were divided into 4 groups of 10 male and 10 female SD rats: The control group received 0.5 mL/animal/day of normal saline whereas the three experimental groups received WCF at doses of 0.125, 0.25, and 0.5 mL/animal/day, respectively. For 4 weeks, the solutions were injected into the femoral muscle of the rats alternating from side to side. Clinical signs, body weights, and food consumption were observed; opthalmological examinations and urinalyses were performed. On day 29, blood samples were taken for hematological and clinical chemistry analyses. Then, necropsy was conducted in all animals to observe weights and external and histopathological changes in the bodily organs. All data were tested using a statistical analysis system (SAS). Results: No deaths were observed. Temporary irregular respiration was observed in male rats of the experimental group for the first 10 days. Body weights, food consumptions, opthalmological examinations, urinalyses, clinical chemistry analyses, organ weights and necropsy produced no findings with toxicological meaning. In the hematological analysis, delay of prothrombin time (PT) was observed in male rats of the 0.25- and the 0.5-mL/animal/day groups. In the histopathological test, a dose-dependent inflammatory cell infiltration into the fascia and panniculitis in perimuscular tissues was observed in all animals of the experimental groups. However, those symptoms were limited to local injection points. No toxicological meanings, except localized changes, were noted. Conclusion: WCF solution has no significant toxicological meaning, but does produce localized symptoms. No observed adverse effect level (NOAEL) of WCF in male and female rats is expected for doses over 0.5 mL/animal/day.

화력발전설비 보일러 튜브 용접부 Phased Array UT(PAUT)의 통계적 신뢰도 평가

최유민(Yu Min Choi),김정석(Chung Seok Kim),박익근(Ik Keun Park) 대한기계학회 2021 대한기계학회 춘추학술대회 Vol.2021 No.4

화력발전설비의 보일러 튜브 용접부에 대한 건전성 검사에는 방사선 투과검사(Radiography Testing)가주로 적용되어 건설 및 예방정비기간에 비파괴검사를 수행하고 있다. 최근 방사선 피폭, 원자력안전법 강화 등의 이슈로 방사선 투과검사를 일반 초음파탐상검사(UT)와 위상배열초음파탐상검사(Phased Array UT)로 대체하기 위한 다양한 실증 연구가 이루어지고 있다. 하지만 UT 및 PAUT 기법은 검사 대상의 재질이나 형상에 따라 검사결과에 차이가 발생하게 되고 검사 및 평가 절차에 영향을 받는다. 따라서 PAUT 기법의 신뢰도를 확보하기 위해서는 표준화된 절차에 따라 다자비교시험(Round Robin Test)을 수행하고 적합한 분석 기법을 통해 평가가 이루어져야 한다. 이를 위해 본 연구에서는 화력발전설비 보일러 튜브에 대한 다자비교시험을 수행하였고 검사 대상의 재질, 형상 등의 조건과 적용된 검사 및 평가절차에 따른 결함 검출 확률(POD), 평균제곱근오차(RMSE) 등 다양한 분석 기법을 적용하여 통계적 신뢰도 평가를 수행하고자 한다. Radiography testing is mainly applied to the integrity of the boiler tube welds of thermal power plants, and is performed during construction and preventive maintenance. Recently, various studies have been conducted to replace radiography testing with general ultrasonic testing (UT) and phased array ultrasonic testing (Phased Array UT) due to issues such as radiation exposure and the revision of the Nuclear Safety Act. However, the UT and PAUT techniques have differences in inspection results depending on the material or shape of the specimen, and are affected by inspection and evaluation procedures. Therefore, in order to secure the reliability of the PAUT method, a round robin test (RRT) must be performed according to a standardized procedure and an evaluation must be performed with an appropriate analysis method. In this study, we performed RRT on the boiler tube of the thermal power plant, and statistical reliability evaluation was performed using various analysis techniques such as probability of detection (POD), root-mean square error (RMSE), etc.
