사진이 발명된 계기에는 과학과 기술이 뿌리 깊게 자리 잡고 있다. 인간의 손이 아닌 기계와 과학적 처리과정을 통해 생성된 이미지는 사실 그대로의 정교한 이미지로만 그치지 않았다. 사진은 대중문화, 예술, 광고, 과학연구 등 정확한 기록성과 사실적 묘사가 필요한 곳이면 어디든지 사용되었으며, 하나의 인류문화로 자리를 잡았다. 그러나 현재 사진교육에서 다루는 사진사는 사진가의 사진성향, 예술적 패러다임의 시대적 변화와 전쟁과 같은 사회적 변화를 중심으로 사진의 흐름을 다루고 있을 뿐 기술적 관점과 같은 다양한 관점에서 바라본 사진사 연구는 부족하다. 본 연구에서는 사진의 과학 기술적 탄생 배경을 중심으로 사진의 기술사를 살펴보았고 중요한 기술적 성취단계에서 사진은 어떤 영향을 받고 변화했는지 각각의 사례를 통해 분석 및 논의하였다. 이러한 관점의 논의는 빠르게 변화하고 있는 현대사진을 이해하는데 도움이 되며 앞으로의 사진 변화를 예측하는데 참고가 될 수 있기에 적지 않은 의미를 가진다. 또한 사진이 기술에 의존적이라는 사실을 이해함으로써 사진전공자들에게 사진기술 및 관련이론을 습득하는 것이 무슨 의미를 가지는지를 깨우쳐 줄 수 있을 것이다.

본 연구의 목적은 투입산출 구조분해분석을 통해 도시가스산업의 성장요인을 분석하는 것이다. 산업연관표에 기초한 Syrquin의 분석모형을 활용하여 1995-2000-2005-2009 기간 동안 우리나라 도시가스산업의 성장요인을 분석하였다. 기간별 산출액 변동요인을 (a)국내 최종수요 증가 효과 (b)수출증가 효과 (c)최종재 수입대체 효과 (d)중간재 수입대체 효과 (e)기술변화 효과 등 5개로 분해하였다. 분석결과, 1995-2009 기간동안 성장기여율이 가장 큰 요인은 (a)국내 최종수요 증가효과(48.4%)와 (e)기술변화 효과(38.6%)인 것으로 나타났다. 1995-2000, 2000-2005, 2005-2009 세 기간별 분석결과, (a)국내 최종수요 증가효과는 점차 감소($84.5%{\rightarrow}18.9%{\rightarrow}15.4%$)하고 있었고, (e)기술변화효과는 상승($7.4%{\rightarrow}70.0%{\rightarrow}42.2%$)하는 양상을 보이고 있었다. 최종수요 기여율의 변화 이유는 1980년대 도시가스 보급이 시작되면서 민간분야의 수요가 지속적으로 확대되다가 1998년 외환위기 이후 성장세의 둔화 및 수요포화 현상과 관련이 있고, 기술변화 기여율 변화 이유는 산업 활동에 있어서 에너지 수급방식이 석탄, 석유 등 전통적인 방식에서 천연가스 등 친환경적 에너지를 사용하는 방식으로 바뀌어 가고 있는 양상을 반영한다고 볼 수 있다. 분석결과 도시가스산업의 성장견인 요인의 중심이 국내 최종수요확대에서 기술변화로 옮겨 가고 있으므로, 친환경적 도시가스산업의 지속적인 성장을 위해서는 주거 주택용보다 산업 활동에서의 도시가스 인프라 확대를 고려할 필요가 있다는 정책적 함의를 지닐 수 있다.

The purpose of this paper is to investigate how the young fashion which maintains a large share of fashion market emerged in the 1960s, its characteristics and what its influences on the contemporary fashion industry are. In particular, I am going to consider the significance of the young fashion by looking at the formation of niche market, the emergence of mass market for fashion, the expansion of aesthetic categories. we will be able to see the 60s young fashion of the young generation who emerged as new consumers in mass consumer culture exerted important influences on the contemporary fashion industry. First, the counterculture of young generation who rebeled against the uniformity of mass production helped the formation of new niche market. Second, the young fashion which pursued the lower prices for fashion made a big contribution to the popularization of fashion. The young generations tendency to demand new things and rapid change coincided with that of inexpensive popular fashion people can buy and change more easily than expensive high fashion. Lastly, the playful tendency of the young fashion expanded the aesthetic boundaries of the clothing, going beyond the uniformity of modernism with the emergency of diverse fashion materials - fabric and textiles - enable by technological development and the miniaturization of forms as revealed in mini skirt.

2016년~2019년까지 지능정보기술 관련 콘텐츠 연구를 메타분석한 결과, 관련 기술이 사회적 화두로 부상한 이후 연구가 유의미하게 증가하였으며, 세부 기술과 관련해서는 가상현실 및 증강현실 기술에 대한 관심이 가장 높았다. 특정한 하나의 기술을 넘어 여러 지능정보기술이 콘텐츠와 어떻게 관련되는지가 탐구되는 경향이었다. 게임의 경우 VR 및 AR기술과 관련하여 연구가 많이 이루어졌고, 빅데이터 기술의 경우 영화 콘텐츠 연구에서 주목하는 경향이었다. 지능정보기술에 대한 기술적 접근을 시도한 연구가 많은 편이었으나, 인공지능 기술과 관련해서는 법적, 제도적으로 주로 조망되는 등 기술별, 콘텐츠 분야별로 차이가 나타났다.

Relative to the outer surface of the mastic coating, the reliability of the available waterproofing resource is determined by the ability to stabilize the structural characteristics in difficult climatic conditions. Organic components of mastic as a result of solar radiation, elevated temperatures and their alternating change, atmospheric oxidants, especially in industrial areas, have a tendency to self-polymerization and loss of low molecular weight components. This is the gradual loss of deformability and the transition to brittleness with its tendency to crack as the reasons for the gradual transition from normal to emergency operating condition.The presented mechanism of functioning of the coating surface indicates the expediency of increasing its components, able to stabilize the structure and prevent changes in deformability.Durability, hydrophobicity, water displacement, water absorption are accepted as estimating indicators. The main dependences of the influence of the lost additional components of mastic on the operational properties of the formed coating characterize the ability to provide successful resistance to environmental influences and longer stability. As a result, mastic acquires additional service life.

Proper PCR primer design determines the success or failure of Polymerase Chain Reaction (PCR) reactions. In this project, we develop GENE-PRIMER, a genomes specific PCR primer design program that is amenable to a genome-wide scale. To achieve this, we incorporated various parameters with biological significance into our program, namely, primer length, melting temperature of primers Tm, guanine/cytosine (GC) content of primer, homopolymeric runs in primer and self-hybridization tendency of primer. In addition, BLAST algorithm is utilized for the purpose of primer specificity check. In summary, selected primers adhered to both physico-chemical criteria and also display specificity to intended binding site in the genome.

Entering into the 21st century, digital culture and the innovation of media technology have drastically changed our understanding of the concept of space. Increased availability of information made possible by technological advancement has, directly or indirectly, contributed to the development of space design, which, in turn, offers a possibility for a new paradigm in space design. Given these fundamental changes, this study seeks to explore how to understand the expansion of the concept of space. In order to answer this question, this study investigates de-materialization tendency in modern architectural design such as transparency, anti-gravity, complexity and simultaneity of space. It examines the interaction-oriented nature of space among human, information and time. Finally, based on concepts such as new hyper-surface, which transcend the limitations of space and time, it explores new emerging trends in space design.

Because of rapid technological advancements, increased data rate support has become the key criterion for future communication medium selection. Multimode optical fibers and multicore optical fibers are well matched to high data rate throughput requirements because of their tendency to support multiple modes through one core at a time, which results in higher data rates. Using the numerical mode solver OptiFiber, we have designed a concentric core fiber by investigating certain design parameters, namely core diameter (µm), wavelength (nm), and refractive index profile, and as a result, the number of channels, material losses, bending losses, polarization mode dispersion, and the effective nonlinear refractive index have been determined. Space division multiplexing is a promising future technology that uses few-mode fibers in parallel to form a multicore fiber. The experimental tests are conducted using the standard second window wavelength of 1,550 nm and simulated results are presented.

In a rapidly changing technology environment, managing and rearranging the patent portfolios is one of the main sources of competitive advantage for firms. This study analyzes the effects of patent portfolio composition on new product introduction related to resource allocation. This study also looks at the moderating role of rearranging the patent portfolios on new product introduction. Our empirical analysis of the global pharmaceutical industry shows that firms with high-value patent portfolios exhibit a tendency to launch new products, and patent portfolio diversity shows a U-shaped relationship with new product introduction. In addition, the patent portfolio rearrangement positively moderates the relationship between patent portfolio diversity and new product introduction. The results are expected to provide implications for firms' patent portfolio composition and patent portfolio rearrangement related to innovation performance such as new product introduction.
