This research considers the characteristics of the plan of the vernacular form of dwelling in KoCheon-Ri village, situated in the Yong-Dong mountain region. As part of this study, an analysis of local diversity is carried out. The current existing village houses in Kocheon-Ri can be categorized according to their floor structure, either as a wooden-floored or an Ondol-floored Kyup-jip(a double row house type). It was found that the wooden-flooded Kyup-jip house has been transformed into Ondol-floorded Kyup-jip due to a range of various factors. In order to clarify the characteristics of the vernacular dwelling type occurring in a particular area, it is important to determine the typical form that appears within the broader area. However, differences is also essential.

Purpose: To compare the effect and complications of treatments for diabetic macular edema. Methods: Literature review using the Korean medical database and the Korean Ophthalmological Society database was performed. Studies used consisted of patients with diabetic macular edema, comparing intravitreal triamcinolone acetonide (IVTA) injection with posterior subtenon triamcinolone acetonide (STTA) injection or intravitreal bevacizumab (IVB) injection, according to visual acuity (VA) outcomes, central macular thickness (CMT), and intraocular pressure (IOP) at 1, 3, and 6 months. Results: In the three studies comparing IVTA injection with STTA injection, IVTA injection demonstrated greater improvement in VA at 1 month and CMT at 6 months. The patients who received IVTA injection had significantly higher IOP at 3 months. In the three studies comparing IVTA injection with IVB injection, IVTA injection demonstrated greater improvement in VA at 3 months and CMT at 6 months. Conclusions: The functional and anatomical improvements are achieved by IVTA injection, STTA injection, and IVB injection for diabetic macular edema, and the effect of IVTA injection is more prominent than other injection types with longer duration.

송(宋) "영조법식(營造法式)" 을 통해 본 목조건축(木造建築) 평면(平面) 척도구성(尺度構成)의 고찰(考察)

이용준,Lee, Yong-Jun 한국건축역사학회 2005 건축역사연구 Vol.14 No.3

In ancient times, architectural design was seen as a critical task in building technologies. Specifically, form, dimension and structural design are of significant. These aspects are associated with each other and to be emerged as a whole. Designing plan dimension was deemed to be the core of design technology due to its close relationship with module system. Thus, its evolution as well as development process typically represents and reflects the spirits and contents of design technologies in ancient China. In China, the materials regarding ancient architectural technology include Yingzaofashi(營造法式) of Song Dynasty and Gongchengzuofazeli(工程做法則例) of Qing Dynasty. They show many aspects concerning materials, structure, scale system and building. In Yingzaofashi, although the length of objects are decided by 'cai(材)' and 'fen(分)', there are no regulations on length, width and height of a building. However, in the construction of ancient buildings, the above mentioned basic scales are very important in both design and construction. The present paper attempts to discuss the significance, namely, the design principles of length, with and height of ancient chinese architecture.

포화 사질토에서 전방 차수층이 쉴드터널 초과 이수압에 미치는영향

이용준,이상덕,Lee, Yong-Jun,Lee, Sang-Duk 한국터널지하공간학회 2011 한국터널지하공간학회논문집 Vol.13 No.4

이수가압식 쉴드공법은 이수압을 적정 수준으로 관리하면 특히 사질토에서 적용성이 우수하지만, 이수압이 낮으면 이수 유출 및 지반변형이 발생하기도 한다. 따라서 이수가압식 쉴드공법에서는 초기 막장압보다 큰 초과 이수압을 가하여 막장의 안정을 유지한다. 그러나 이수압이 너무 높으면 전방 지반의 수동 파괴를 유발하므로 전방 지반의 수동 파괴 위험성을 배제하고 이수압을 증가시키는 방법으로 막장 전방에 수평 차수층을 설치하는 방안이 있으나 그 위치와 규모 및 효과가 잘 알려져 있지 않다. 따라서 본 연구에서는 포화된 사질토에서 막장 전방에 차수 그라우팅을 적용할 경우에 발생하는 효과를 규명하기 위하여 모형실험을 수행하였다. 실험에서는 차수층의 위치와 길이를 변화시거면서 이수의 유출이나 지반 파괴 이전까지 이수압을 가하여 최대 이수압과 지반 변위 및 이수의 유출로 인한 파괴 형상을 측정하여 분석하였다. 실험 결과, 전방 차수층이 없는 경우에 최대 이수압과 초과 이수압은 토피고에 선형비례 하였으며, 차수층이 존재하는 경우에는 차수층이 없는 경우보다 이수압을 크게 가할 수 있어서 전방 차수층이 막장 안정성을 증대시킬 수 있다는 것을 확인할 수 있었다. 막장 안정성 증대에 가장 큰 영향을 주는 적정 차수층의 규격은 길이 1.0 ~ 1.5D, 설치높이 1.0D로 나타났다. 초기 막장압 대비 최대 이수압의 비로 막장의 자립 안전율(F)을 제안할 수 있으며, 전방 차수층을 적정 위치에 설치할 경우 초기 막장압보다 3.5~4.0배 크게 이수압을 가할 수 있는 것으로 나타났다. Slurry type shield would be very effective for the tunnelling in a sandy ground, when the slurry pressure would be properly adjusted. Low slurry pressure could cause a tunnel face failure or a ground settlement in front of the tunnel face. Thus, the stability of tunnel face could be maintained by applying an excess slurry pressure that is larger than the active earth pressure. However, the slurry pressure should increase properly because an excessively high slurry pressure could cause the slurry flow out or the passive failure of the frontal ground. It is possible to apply the high slurry pressure without passive failure if a horizontal impermeable layer is located in the ground in front of the tunnel face, but its location, size, and effects are not clearly known yet. In this research, two-dimensional model tests were carried out in order to find out the effect of a horizontal impermeable layer for the slurry shield tunnelling in a saturated sandy ground. In tests slurry pressure was increased until the slurry flowed out of the ground surface or the ground fails. Location and dimension of the impermeable layer were varied. As results, the maximum and the excess slurry pressure in sandy ground were linearly proportional to the cover depth. Larger slurry pressure could be applied to increase the stability of the tunnel face when the impermeable layer was located in the ground above the crown in front of the tunnel face. The most effective length of the impermeable grouting layer was 1.0 ~ 1.5D, and the location was 1.0D above the crown level. The safety factor could be suggested as the ratio of the maximum slurry pressure to the active earth pressure at the tunnel face. It could also be suggested that the slurry pressure in the magnitude of 3.5 ~4.0 times larger than the active earth pressure at the initial tunnel face could be applied if the impermeable layer was constructed at the optimal location.

이용준,김원제,Lee, Yong-Jun,Kim, Won-Je 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.4

본 연구는 OTT 이용자 320명을 대상으로 큐레이션 서비스 수용에 영향을 미치는 영향 요인을 살펴봄으로써 콘텐츠 전략을 수립하는데 요구되는 시사점을 제공하고자 하였다. 연구결과를 살펴보면, 첫째, 혁신성이 성과기대에 미치는 영향을 살펴본 결과, 혁신성은 성과기대에 정적 영향을 미치는 것으로 나타났다. 둘째, 혁신성이 노력기대에 미치는 영향을 살펴본 결과, 혁신성은 노력기대에 정적 영향을 미치는 것으로 나타났다. 셋째, 성과기대가 지속이용의도에 미치는 영향을 살펴본 결과, 성과기대는 지속이용의도에 정적 영향을 미치는 것으로 나타났다. 넷째, 노력기대가 지속이용의도에 미치는 영향을 살펴본 결과, 노력기대는 지속이용의도에 정적 영향을 미치는 것으로 나타났다. 다섯째, 사회적 영향력이 지속이용의도에 미치는 영향을 살펴본 결과, 사회적 영향력은 지속이용의도에 유의한 영향을 미치지 못한 것으로 나타났다. 여섯째, 촉진조건이 지속이용의도에 미치는 영향을 살펴본 결과, 촉진조건은 지속이용의도에 유의한 영향을 미치지 못한 것으로 나타났다. 이상의 결과는 OTT 이용자들이 큐레이션 서비스에 대한 성과기대와 노력기대를 높게 인식할수록 지속이용의도도 높아지는 것으로 평가할 수 있다. 본 연구는 OTT 큐레이션 서비스의 지속이용의도에 영향을 미치는 요인들을 검증하고, UTAUT 모델의 확장 가능성을 확인하였다는 점에서 의의가 있다. This study aimed to provide implications required to establish a content strategy by examining the influencing factors affecting the acceptance of curation services for 320 OTT users, and the main results are as follows. First, innovativeness was found to have a positive effect on performance expectations. Second, innovativeness was found to have a positive impact on the effort expectation. Third, performance expectation had a positive effect on the intention to use continuously. Fourth, it was shown that the effort expectation had a positive effect on the intention to use continuously. Fifth, social influence was found to have no significant effect on the intention to use continuously. Sixth, it was found that the facilitating conditions did not significantly affect the intention to use continuously. The above results can be assessed as the higher the OTT users perceive the performance and effort expectations of the curation service, the higher their intention to continue using them. This study is meaningful in that it verified the factors affecting the intention to use the OTT curation service and expanded the UTAUT model.

송(宋) 《영조법식(營造法式)》 중 월량(月梁) 보머리 가공 규범에 대한 고찰

이용준,Lee, Yong-Jun 한국농촌건축학회 2019 농촌건축 : 한국농촌건축학회논문집 Vol.21 No.3

Woolyang(月梁) is a beam which whole shape is curved like a so-called moon(月). According to the ${\ll}$Yeongjobeosig(營造法式)${\gg}$, In the case of beams installed under the ceiling of a wooden building, it is used by manufacturing them in Woolyang(月梁) for maximum visual decorative effects as the shape is exposed. In order to achieve the end of a beam that is manufacturing in Woolyang(月梁), it is important to process it in a suitable size and shape for a given situation to achieve a combination with other members around it. However, in the "營造法式", the standard of production of the Woolyang(月梁) is divided into Myeongbog(明?), Chagyeon(箚牽), Pyeonglyang(平梁), and the height of each beam head is divided into 21分$^{\circ}$, 15分$^{\circ}$, 25分$^{\circ}$, but it is not possible to look at any more specific reference. In this paper, try to consider the principle of Woolyang(月梁) manufacturing and its normative contents which were indirectly proposed in the ${\ll}$Yeongjobeosig(營造法式)${\gg}$.

1/5축소 모형실험에 의한 조립식 터널라이닝 (PCL)의 내진성능 평가

이용준,정형식,이두화,조병완,Lee, Yong-Jun,Chung, Hyung-Sik,Lee, Doo-Hwa,Jo, Byung-Wan 한국터널지하공간학회 2004 터널기술 Vol.6 No.1

최근 현장 타설 콘크리트 터널 라이닝의 시공 및 유지관리상 문제점을 개선하기 위해 노르웨이에서 개발된 프리캐스트콘크리트라이닝에 대한연구가 활발히 진행되고 있다. 그러나 북유럽지역에서는 지진이 거의 발생되지 않기 때문에 PCL공법 적용시 지진하중으로 인한 영향을 고려하지 않았다. 따라서 PCL공법을 국내에 도입하기 위해서는 지진하중으로 인한 PCL의 영향분석을 선행하여야 할 것으로 판단되어 본 연구에서는 지진하중으로 인한 PCL의 안정성 검토를 수행하고자 하며 이를 위해 실물을 1/5로 축소한 모델체에 대한 진동대 실험을 수행하였으며 PCL의 내진성능평가를 수행하였다. 연구결과, 대섬도터널에서 PCL공법을 적용할 경우, 국내의 내진설계 기준에 만족하는 결과를 얻을 수 있었다. Precast Concrete Lining (PCL) is invented in order to resolve the problem of the cast-in-place concrete lining in Norway, However PCL could not consider the effect of earthquake because an earthquake rarely occurs in the region of Northern Europe, Consequently, the analysis of the effect of earthquake on PCL should be made before introducing PCL to Korea. The purpose of this research is to evaluate the stability of tunnel applying PCL in the case of earthquake. To evaluate the seismic performance of PCL, we used shaking table apparatus by 1/5 scale down model. The result of this research is as shows that deep tunnells satisfied for Korea seismic design criteria.
