In recent years, the challenge of higher energy efficiency has emerged as urban buildings have become taller, and the area of window glasses has increased. To address the problem of energy efficiency in buildings, research on smart windows is being actively conducted. In this study, an accelerated experiment for thermal stability was conducted to fabricate a liquid crystal cell applicable to external windows. It was confirmed from the study that the function is maintained even in a high-temperature external environment through the change in transmittance by voltage. Compared with the initial transmittance, after the passage of time, the smart window cell to which the sealant was applied showed a small change in transmittance of 1~2%. This result confirmed the thermal stability of the liquid crystal-based smart window.

음악제작에 쓰이는 음성합성엔진은 악기 소리와 음색의 합성에 머물던 과거의 신디사이저와는 달리, 인간의 목소리를 각 음소에 따라 샘플화하여 탑재함과 동시에 각 음소의 연결을 주파수 영역 내에서 자연스럽게 처리함으로써 실제 사람이 노래하는 것과 같은 수준까지 도달하게 되었다. 사용자들은 이러한 음성합성엔진을 음악제작에 국한하여 쓰지 않고 캐릭터를 활용한 콘서트, 영상제작, 음반, 모바일 서비스 등 2차 창작물로 새로운 음악의 형태를 창조하며 문화적 패러다임을 바꾸어 나가고 있다. 현재 음성합성엔진 기술은 악보 편집기를 통하여 사용자가 원하는 음과 가사, 그리고 음악적 표현 파라미터를 입력한 뒤, 실제 가성 샘플을 데이터베이스에서 가져와 합성엔진에서 발음들을 조합, 연결하여 노래하는 것을 가능하게 한다. 이러한 컴퓨터음악 기술의 발전으로 인해 파생된 새로운 음악 형태들은 문화적으로 큰 반향을 불러일으키고 있다. 이에 따라 본 논문은 구체적 활용 사례를 살펴보고 합성기술을 탐색함으로써, 사용자들이 음성합성엔진을 이해하고 습득하는 데 기여함과 동시에 그들의 다양한 음악제작에 도움이 되고자 한다. Differently from instruments which synthesized sounds and tones in the past, voice synthesis engine for music production has reached to the level of creating music as if actual artists were singing. It uses the samples of human voices naturally connected to the different levels of phoneme within the frequency range. Voice synthesis engine is not simply limited to the music production but it is changing cultural paradigm through the second creations of new music type including character music concerts, media productions, albums, and mobile services. Currently, voice synthesis engine technology makes it possible that users input pitch, lyrics, and musical expression parameters through the score editor and they mix and connect voice samples brought from the database to sing. New music types derived from such a development of computer music has sparked a big impact culturally. Accordingly, this paper attempts to examine the specific case studies and the synthesis technologies for users to understand the voice synthesis engine more easily, and it will contribute to their variety of music production.

The effects of longitudinal heat conduction on the performance of heat transfer surfaces are investigated by using a single-blow method. In the transient testing method for determining the heat transfer characteristics, exponential inlet temperature variations are made by using screen-mesh heater with small time constant and low frontal velocities of the test section, and the experimentally determined inlet temperature profile is used as the inlet fluid temperature condition. The effects of longitudinal heat conduction are negligible only if $\gamma^\act<0.05\;and \;N_{tu}\le3$ and should be considered if $N_{tu}\le3$ The test results ate compared with the existing theoretical and experimental data and the validity of this technique is confirmed by the good agreement.

A single blow, transient testing method for determining the heat transfer characteristics of heat exchanger surfaces are presented. The exponential inlet temperature variations were made using screen mesh with small time constant and frontal velocities of the test section. The system is used to investigate the usefulness of a model with exponential inlet temperature variations. A data reduction program is developed to calculate the temporally and spatially averaged heat transfer coefficient using the measured disturbance and response of the fluid temperature. The results are compared with the existing theoretical and experimental data for parallel plate stacks. It was recommended to take an average for the time greater than the 99% of the final temperature had reached in order to obtain fairly good results.

The amount of electric power for photovoltaic power generation depends on the location of the power plant and the direction of solar cell. The solar cell controls the generation of solar power plants. Therefore, the structure of solar cell, manufacturing method, and optic technology were factors contributing to increased solar cell efficiency; however, the technical limit has been reached. Herein, we propose a new method to increase the solar cell efficiency using a wavelength conversion technology that converts ultraviolet and infrared rays, which are not effectively used in solar cells, into effective wavelength of solar cell. We used fluoride $Na(Ca)YF_4$ phosphor for wavelength conversion. Then, a wavelength-conversion fluorescent paste, prepared using an organic-silicon binder, was used to prepare a film that was applied to Si solar cells. It was confirmed that conversion efficiency improved by 5% or more.
고다르 〈카르멘이라는 이름(Prénom Carmen)〉에 나타난 영화 사운드의 미학적 고찰
박병규(Byung-Kyu Park) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.8
본 논문은 들뢰즈의 영화미학, 메를로-퐁티의 현상학적 관점에서 고다르 〈카르멘이라는 이름〉의 사운드를 고찰하고 있다. 현악 사중주의 리허설 장면은 음악 자신을 비추는 거울 이미지로서, 주 내러티브와의 단절 속에 현재와 과거의 식별 불가능성을 갖는 결정체-이미지가 된다. 한편, 도시 소음과 파도는 순수시지각적(음향적) 이미지로 구성된 배아로서, 소리의 병치와 대체, 그리고 지향적 연결을 통해 보이는 것과 충돌하는 순수 음향적 결정체로 성장하게 된다. 그러나 이러한 음향적 모순들도 메를로-퐁티의 변증법적 사유를 통해 ‘단일 운동’으로서의 통합된 소리 범주로 나아가게 되며, 팝음악과 고전음악의 변증법적 사운드 운용조차도 더 이상 장르적 대립이 아닌 소리라는 질료적 범주로 통합된다. 본 연구는 고다르 영화의 사운드 미학을 철학적 사유를 통해 풀어나감으로써 기존연구와 차별화하고 있다. This paper examines the sound of Godard’s 〈Prénom Carmen〉 from Deleuzes film aesthetics and Merleau-Pontys phenomenological point of view. The rehearsal scene of a string quartet is a mirror-image that illuminates the music itself, and becomes a crystal-image with the indiscernibility of the present and the past in the break with the main narrative. On the other hand, urban noise and waves are the seeds composed of pure optical (sound) images and grow into pure sound crystals that collide with what is seen through the juxtaposition, substitution, and intentional connection of sound. However, these sound contradictions also lead to the integrated sound category as a sole movement through Merleau-Pontys dialectical thought, and even the dialectical sound management of pop and classical music is no longer a confrontation of the genre, but is integrated into the materialistic category of sound. This study is differentiated from the existing research by solving the sound aesthetics of the Godard’s film through philosophical thought.

A thermal mass air flow sensor, which consists of a micro-heater and thermal sensors on the silicon-nitride thin membrane structure, is micro-fabricated by MEMS processes. Three thermo-resistive sensors, one for the measurement of microheater temperature, the others for the measurement of membrane temperature upstream and downstream of the micro-heater respectively, are used. The micro-heater is operated under the constant temperature difference mode via a real time controller, based on inlet air temperature. Two design models for microfabricated flow sensor are compared with experimental results and confirmed their applicabilities and limitations. The thermal characteristics are measured to find the best flow indicator. It is found that two normalized temperature indicators can be adopted with some advantages in practice. The flow sensor with this control mode can be adopted for wide capability of high speed and sensitivity in the very low and medium velocity ranges.
