안정현,이주명 사단법인 한국조형디자인협회 2022 조형디자인연구 Vol.25 No.3

This study attempted to explore the thinking, behavior, and purpose of craftsmen’s production activities by reflecting the necessity of design thinking education that has been continuously discussed in the crafts field business. The qualitative methodology centered on semi-structured interview analysis of craftsmen was adopted, and the craft value, tool, scope, and craft characteristics were derived as the four main attributes of craft, based on the 'Basic Research for the Establishment of Mid- and Long-term Promotion Policies for Craft Culture' by the Ministry of Culture, Sports and Tourism. In addition, interview questions were organized based on prior research on design thinking and process, and the subjects were limited to craftsmen with at least 10 years of experience in ceramic, wooden, and metal crafts. The content of their interviews was put to the thematic analysis based on emic coding, which is to classify inductively according to the viewpoints of participants. The findings demonstrate the possibilities of design thinking and process as another tool for craftsmen to take in their realistic crafts works. Stage 1 Empathize, Stage 2 Define, and Stage 3 Ideate in the five-stage process of D.School had similar aspects to the thinking and acting that craftsmen engaged in through a series of making processes. The selective utilization of the stages of the design thinking will contribute to the development of craftwork reflecting the changes of the times. 본 연구는 공예품 제작 실무 현장에서 지속적으로 논의 되었던 디자인사고 교육의 필요성을 반영하여 공예가 제작활동의 사고, 행동 및 목적을 탐구하고자 하였다. 따라서 공예가 면담분석 중심의 질적 연구방법을 채택하였고, 선행연구인 문화체육관광부 주관의 ‘공예 문화 중장기 진흥정책 수립을 위한 기초연구’ 자료를 주축으로 공예 가치, 도구, 범위 그리고 공예품 특성을 공예를 구성하는 4가지 속성으로 도출하였다. 또한 디자인사고와 프로세스의 선행연구를 토대로 면담 질문을 구성하였고 면담 참여자는 도자공예, 목공예, 금속공예를 전공, 최소 10년 이상의 제작과 전시 경험을 가진 공예가로 한정하였다. 면담내용은 참여자의 관점에 따라 귀납적으로 분류하는 에믹코딩(Emic Coding)으로 주제분석(Thematic Analysis)하였다. 분석결과 디자인사고와 프로세스를 도구로 활용하여 공예작업 과정의 선택적 대입 가능성을 확인하였다. 공예가들이 기존에 진행해온 일련의 제작과정 사고 및 행위는 D.School 디자인사고의 5단계 프로세스 중 1단계 공감(Empathize), 2단계 정의(Define), 3단계 상상하고 관념화하기(Ideate)와 유사점이 존재하였다. 본 연구를 통하여 공예가들이 선택적으로 디자인사고의 단계별 활동을 활용한다면 시대적 변화를 반영한 공예품 개발에 기여할 수 있을 것이다.

안정현 空軍士官學校 1991 論文集 Vol.30 No.-

Forced vital capacity (FVC), maximal voluntary ventilation (MVV) and forced expiratory flow rate 25~75%(FEER 25~75%) were measured in seven trained and 7 untrained male subjects, before and after submaximal treadmill exercise. There were measued by spinometer (Collins Co, USA) with subjects. There was a significant larger FVC in marathon runners but no significant FEV_1% and MVV. Slight increments are found in postsubmaxiaml exercise FEV_1% and MVV of pulmonary function.It is likely that this larger FVC was due to endurance training in growth period. Slight increments of post-submaximal exercise FEV_1% and MVV are expected to significantly increase in training with optimum work load and duration and specific tranining of chest muscle developing

Gossypiboma is an uncommon postoperative complication, referring to inflammatory response caused by gauze or sponge left in the body after an operation, and its prevalence is reported to be 1/1,000-1/10,000. In the area of otorhinolaryngological surgery, there have been reports on inflammation caused by gauze left in the spaces around the neck and tonsils, but few case reports have been made based on imaging examinations such as computed tomography and magnetic resonance imaging. The authors are going to report a recent case of a 22-year-old man with infection caused by intranasal packing material that was left after rhinoplasty and pushed into the space made by hump removal.

안정현,민유홍 한국피부과학연구원 2014 대한피부미용학회지 Vol.12 No.5

Although a number of depigmenting agents have already been developed, the majority of them produce adverse side-effects. There is, therefore, a constant need for melanogenesis inhibitors. In this study, the hydrodistilled essential oil from the apricot seeds (Armeniacae Semen) was investigated for the activity against tyrosinase and melanogenesis. The apricot seed essential oil inhibited mushroom tyrosinase with an IC50 value of 1.11 μg/mL, which is more potent than the activities of kojic acid (IC50 5.07 μg/mL), ascorbic acid (IC50 54.0 μg/mL) and lemon essential oil (IC50 432.8 μg/mL). Benzaldehyde, the major component of the apricot seed essential oil, also showed similar level of inhibition (IC50 0.94 μg/mL). These results suggest that the activity of the apricot seed essential oil is due to benzaldehyde. The apricot seed essential oil decreased tyrosinase activity and melanin content of murine B16F10 melanoma cells in concentrationdepentent manners. No cytotoxic effect was seen in B16F10 and human CCD-1064sk skin fibroblast cells treated with up to 100 μg/mL of the apricot seed essential oil. These results indicate that the apricot seed essential oil may have potential for the application in aromatherapy and the development of depigmenting agents.

동작 전처리 기법을 활용한 실시간 군중 애니메이션 시스템

안정현,원광연 한국정보과학회 2007 정보과학회논문지 : 시스템 및 이론 Vol.34 No.3

field on crowd animation can be classified into two major categories. One is to offer realism of the crowd motion and the other is to improve speed of the animation. For the last decade, a lot of research on realism and behavior of crowd have been presented. But lately, research on improving speed seems like more interesting. Therefore, in this paper, we conducted an experiment to analyze what is the main bottleneck of crowd animation. As the result, we find out one of the most important bottleneck is the number of joints transformed in each animation frame. In order to resolve this problem we propose a novel level-of-detail technique ‘motion level-of-detail’, which is a joint-reduction technique operated in the pre-processing time. We used a non-linear optimization, SQP (sequential quadric programming), to generate the low detailed motions 애니메이션을 위한 연구분야는 동작의 사실성 제공과 속도향상의 두 가지 측면으로 구분된다. 최근 엔터테인먼트 산업의 발달로 군중 애니메이션은 디지털 콘텐츠 제작의 필수요소로 자리 잡았으며, 애니메이션의 속도향상을 위한 노력이 계속되고 있다. 이러한 추세에 맞춰, 본 논문에서는 군중 애니메이션의 속도저하에 영향을 미치는 요인들을 실험을 통해 검증하고, 실험 분석을 토대로 전처리 시스템을 설계한다. 동작 전처리 모듈은 제시된 애니메이션 시스템의 핵심 모듈로서 관절의 개수를 동작의 상세도에 따라 다양한 레벨(level-of-detail)의 동작들로 재구성한다. 실제 애니메이션 과정에서는 카메라와 가상환경 내부에 존재하는 캐릭터의 관계를 토대로 적절한 레벨의 동작을 적용하여 전체 시스템의 속도를 향상시킨다. 동작전처리 방법(motion level-of-detail)은 동작분석과 동작단순화 과정으로 분류되는데, 비선형 최적화 방법의 하나인 SQP를 활용하여 다양한 상세도 레벨의 동작들을 계산한다. 본 논문에 제시한 전처리 방법은 동작편집 등 캐릭터 애니메이션의 다양한 분야에 유용하게 활용될 수 있다.

The purpose of this study was to examine the structural relationships among spousal autonomy support and the well-being and the depression, mediated by basic psychological needs of married women based on the self-determination theory. Married women(N = 443) completed self-report questionnaires on autonomy support, basic psychological needs, well-being, and depression. The data of 427 was analyzed using a structural equation modeling analysis. The main results are as follows. First, the spousal autonomy support had a positive effect on married women’s well-being, mediated by the satisfaction of basic psychological needs, and had a negative effect on depression. Second, it was found that the spousal autonomy support negatively affects depression, mediated by the frustration of basic psychological needs. Third, it was found that the frustration of basic psychological needs of married women had a positive effect with depression, but was not statistically significant with well-being. The implications of this study are significant in that empirical evidence of self-determination theory has been extended to the domain of married women and can be used as basic data for psychotherapy intervention of married women.
