한정엽(Jung-Yeob Han),안진근(Jin-Keun Ahn) 한국콘텐츠학회 2010 한국콘텐츠학회논문지 Vol.10 No.11

최근 공간디자인은 온 라인과 오프라인이 융합된 혼합현실 공간으로 진화하고 있다. 그러나 혼합현실공간의 기준과 척도는 제시된 바 없으며 융합체계로서의 미디어환경과 표현방법 또한 연구가 미흡한 실정이다. 따라서 미디어환경 특성 연구는 유비쿼터스 기술 기반, 혼합현실 공간에서의 임계점으로서 중요한 위치를 차지하는 동시에 다양한 체험공간의 구축방법으로서 혼합현실 공간적 분별을 위한 기준점으로서 네 가지 미디어 환경과 표현특성을 제안하고자 한다. 1)현실공간은 인간의 시?지각에만 의존하여 보여지는 미디어환경으로 디지털 기술기반의 새로운 소재와 LED 등을 이용한 표현방법으로 발전하고 있다. 2)증강현실공간은 정보기기를 이용한 보여 지는 미디어환경으로 다양한 2D, 3D 콘텐츠가 증강되어 표현된다. 3)가상공간은 미디어 기기에 완전히 의존하여 구현되는 환경으로 공간적, 물리적 제약 없이 완벽한 그래픽정보로 표현된다. 4)증강가상공간은 가상의 스튜디오를 구성, 디스플레이를 통해서만 시청할 수 있는 환경으로 실제의 사물과 그래픽정보가 융합되어 표현된다. 혼합현실공간의 미디어 환경과 표현특성은 체험의 목적에 따라 융합, 혼합, 조합되어 공간적, 시간적, 정보적으로 제약 없이 체험 가능한 지능형정보공간으로 구현 가능하다는 것이다. 향후 미디어환경 특성에 따른 콘텐츠의 유형적 특성 연구가 필요시된다. In these days, space design is evolving to the mixed reality space where fused on-line and off-line. But, standard and measure of mixed reality space has not been suggested and there has been little research about media environment and expression method as a mixed system either. That’s why here I suggest four media environments and their characteristics that act not only as a critical point in the mixed reality space based on ubiquitous technology but also as a standard for spatial discerning. 1) Real space that is a media environment only seen by human visual and tactical sense is evolving using expression methods like new materials based on digital technology and LED. 2) Augmented reality space is a media environment using information instruments is expressed with diverse 2D and 3D contents. 3) Cyber Space is a environment depends totally on media instruments is produced by perfect graphic information without any spatial and physical limitations. 4) Augmented cyber space is realized only through the displays in cyber studio and is a space where real objects and graphic information are mixed. Depending on the purpose of the experience, media environment and expressional characteristics of mixed reality space can be fused, blended, and mixed, and that can be realized to the intelligent information space where one can experience without spatial, visual, informational limitations. In the future, studies on physical characteristics of contents according to the media environment characteristics are necessary.

한정엽 ( Jung Yeob Han ) 한국공간디자인학회 2016 한국공간디자인학회논문집 Vol.11 No.1

(Background and Purpose) Markets & Markets predicted that the HMD-related market would grow by as much as 49.1% to be worth approximately KRW 17.7 trillion by 2020. Global IT companies are making full-fledged inroads into virtual reality(VR) market while Facebook and YouTube are building platforms enabling upload of 360-degree images and offering free view of 360-degree contents. Little study has been conducted on the type and characteristics of VR contents, protection techniques, etc., in the rapidly developing VR market. Thus, this study was intended to analyze the types of contents with a focus on the most popular VR platforms offered to Oculus Rift and Samsung Galaxy Gear and to present direction for VR content design. (Method) For that, we focused on 48 contents, selecting 25 types of experience in 3 areas, 13 games, and 10 apps in accordance with VR platform registration standards on November 10, 2015 and then compiled the sheets specifying the types and details of contents and analyzed them. (Results) Based on the experience offered by joint platforms, game, and app platforms, each specific types can be analyzed as follows: First, the experiential VR contents were classified into 3 sub-categories such as entertainment, heritage, and experience & knowledge base. Second, the game VR contents were divided into 2 sub-categories, depending on the switch of direction and use of touch pad. Third, app TV contents were classified into prosumer VR platforms on which users can produce and share VR contents such as 360-degree films, photos, current affairs, documentaries, psychotherapy, etc. Based on respective sub-categories, the details of contents can be analyzed as below: First, experiential VR contents can be produced through 360-degree live imaging, 3D low polygon-based simulation, professional rendering program-based 360-degree animation. Second, VR environment can be presented through VR user-experienced design and VR user interface design. Third, the substance of VR contents can be presented as the experiential and educational contents based on user experience and knowledge, VRgame contents of various genres, and VR platform sharing individual experiences. (Conclusions) VR contents overcame unfavorable environment and have shown drastic development, driven by VR-related hardware companies, controller companies, game engine(Unreal, Unity, CryENGINE, etc), middleware companies, etc., in 2015. This suggests that 2D and 3D graphic-centric VR environment is evolving into optimized VR contents founded on controller and common platforms. Specifically, it means the formation of specialized locality for special experience, development of contents based on time, professional experience, and experts’ experience and knowledge, and advancement of virtual games built on new system. VR platform will also set the tone for forming new types of VR industrial ecosystem enabling sharing of various VR contents created by individuals, rather than mere consumption of VR contents that have been provided unilaterally.

한정엽(Jung Yeob Han),김유철(Yu Cheol Kim) 대한안과학회 2016 대한안과학회지 Vol.57 No.8

목적: 백내장을 가진 한국성인에서 안구계측치의 분포와 신체계측치와의 상관관계에 대하여 알아보고자 하였다. 대상과 방법: 백내장 수술을 시행한 150안(150명)을 대상으로 의무기록을 후향적으로 분석하였다. 신체계측치는 신장과 몸무게 그리고 체질량지수를 이용하였으며 안구계측치는 술 전에 비접촉식 저간섭성반사계로 측정한 안축장, 전방깊이, 각막곡률, 수정체두께, 중심각막두께를 이용하여 안구계측치와 신체계측치의 상관관계를 선형회귀분석하였다. 결과: 평균 나이는 67.44 ± 10.83세였다. 평균 신장, 체중, 체질량지수는 각각 157.24 ± 9.16 cm, 60.50 ± 10.18 kg, 24.47 ± 3.59kg/㎡였으며 평균 안축장, 전방깊이, 평균각막곡률, 수정체두께, 중심각막두께가 각각 23.51 ± 0.80 mm, 3.23 ± 0.42 mm, 44.49 ± 1.33 diopter, 4.44 ± 0.42 mm, 534.64 ± 31.90 μm로 측정되었다. 신장은 안축장, 전방깊이와 유의한 양의 상관관계가 있었으며, 평균각막곡률과 유의한 음의 상관관계가 있었고 중심각막두께, 수정체두께와는 연관성을 보이지 않았다. 체중은 안축장과는 유의한 양의 상관관계가 있었으며 체질량지수는 모든 안구계측치와 상관성을 보이지 않았다. 나이가 증가할수록 신장, 체중, 전방깊이는 유의한 감소를 보였으며 평균각막곡률, 수정체두께는 유의한 증가를 보였으나 안축장, 중심각막두께와는 연관성을 보이지 않았다. 결론: 신장이 클수록 안축장이 길어지며 전방깊이는 깊어지고 평균각막곡률은 편평해지는 경향이 있다. 연령이 증가할수록 전방깊이는 얕아지고 평균각막곡률은 가팔라지며 수정체는 두꺼워지는 경향을 가진다. Purpose: To evaluate the relation between ocular biometry and anthropometric parameters in Korean adults with cataracts. Methods: The preoperative medical data of 150 eyes (150 patients) who underwent cataract surgery from November 2015 to March 2016. Anthropometric parameters include height, weight and body mass index (BMI). Ocular biometry includes axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness. The relation between ocular biometry and anthropometric parameters was evaluated using linear regression analysis. Results: The mean age was 67.44 ± 10.83 years. The mean height, weight and BMI were 157.24 ± 9.16 cm, 60.50 ± 10.18 kg and 24.47 ± 3.59 kg/㎡. The mean axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness were 23.51 ± 0.80 mm, 3.23 ± 0.42 mm, 44.49 ± 1.33 diopter, 4.44 ± 0.42 mm and 534.64 ± 31.90 μm. The height showed a significant positive relationship with axial length and anterior chamber depth and a significant negative relationship with average corneal curvature. However, there was no significant relationship with the central corneal thickness or lens thickness. The weight showed significant positive relationship with axial length. BMI was not related to any anthropometric parameters. Age showed a significant positive relationship with average corneal curvature and lens thickness and a negative relationship with height and anterior chamber depth. Conclusions: As height increases, the axial length and the anterior chamber depth increase and the corneal curvature become flatter. As age increases, the anterior chamber depth becomes shallower, the corneal curvature becomes steeper and the lens thickness increases.

정신문화 중심도시 조성을 위한 공간디자인 정책연구

한정엽 ( Jung Yeob Han ) 한국상품문화디자인학회 2014 상품문화디자인학연구 Vol.38 No.-

박근혜 정부는 국정기조 및 문화융성차원의 3대 국정과제로서 ‘인문·정신문화 진흥’을 제시하고 있다. 경북도 역시, 인문·정신문화의 본산으로서 신 도청 일원에 정신문화 중심도시 조성을 목표로 하고 있다. 이에 본연구는 국가균형발전을 위하여 정신문화 중심도시 조성에 필요한 공간디자인 정책방안을 제안하는데 목적이 있다. 연구의 방법은 관련 문헌연구를 통하여 이론적 배경을 고찰하고 정신문화 중심도시 조성에 필요한 관련 문헌연구 및 국내외 사례수집 을 통하여 정성적 방법으로 분석한다. 공간디자인 정책적 방안으로는 첫번째, 정신문화 중심도시 추진단계로서 대응투자계획, 재원조달계획, 사업추진에 의한 운영조직구성, 사업평가단 운영을 제안하였다. 두 번째, 정신문화 중심도시의 계획단계로는 사업조성의 당위성, 비전 및 목표, 기본전략, 공간계획 순으로 정신문화 중심화를 위한 공간디자인 정책을 제시하였다. 이를 통한 파급효과로는 정신문화콘텐츠를 활용한 부가가치 창출 및 지역 문화역량강화가 기대된다. 특히 거시적으로는 국가균형발전 모델로서 국가 브랜드 가치가 제고되고 미시적으로는 경북 신도청 일원이 정신문화 수도이며 한류문화의 상징성으로서 대표되며 저변 확대를 기대할 수 있다. As part of its national agenda and one of the government’s top three plans to advance culture, the Park, Geun-Hye administration proposes to promote a “humanities and spiritual culture.” This study proposes spatial design policies to underpin the creation of a Korean hub city of spiritual culture, contributing to balanced national development. It also examines the theoretical background by exploring related literature, conducting a qualitative analysis by studying the literature and collectingcase studies in Korea and abroad to guide the creation of a hub city of Korean spiritual culture. For the first stage of the spatial design policy (promoting the hub city), this paper proposes an investment plan, funding plan, and structure for an operational organization based on business and the work of a business evaluation team. For the second stage (planning the hub city), it offers a rationale for the project, as well as a vision, an objective, basic strategy, and a spatial plan. This hub city is expected to create, through a ripple effect, added value through spiritual culture, and the reinforcement of regional cultural strengths. On a macro level, the national brand value will be enhanced as a model for balanced national development; on a micro level, we can expect Gyeongbuk’s new provincial government building area to become the capital of spiritual culture and a symbol of the Korean wave.
