헤어드라이어의 경우 소비자들이 상품에 대한 충분한 지식을 갖고 구매를 하게 되므로 특별히 판매원의 의견과 서비스를 받지 않고 직접 선택하는 경향이 높아 상품의 포장과 라벨링이 매우 중요한 요소로 지적되고 있다. 본 개발에서는 기존의 금속 열선에서 벗어나 "세라믹 히터"를 이용하여 원적외선의 방사 및 고효율의 열량을 낼 수 있는 방법과 가전제품에서 가장 전자파가 발생되는 헤어드라이기에 전자파 차폐 기술을 적용하여 고성능 및 다기능성의 요구에 부합하고자 한다.

The purpose of this study is to investigate the loess dyeability of soybean fabric using loess as colorants. Recent days, various textile products such as inner wears, sheets and interior goods are manufactured using materials dyed with loess emphasizing its improved metabolism, anti-bacterial, deodorizing properties, and far infrared ray emissions. Soybean fabric was dyed with loess solution according to concentration of loess, dyeing temperature and dyeing time. To improve washing fastness, soybean fabric and dyed soybean fabric with loess were mordanted by mordanting agents such as sodium chloride(NaCl), Acetic acid(CH₃COOH) and Aluminium Potassium Sulfate(AlK(SO₄)₂·12H₂O). Dyeability and color characteristics of dyed soybean fabric were obtained by CCM observation. Particle size distribution of loess, the dyeability(K/S) of soybean fabric, morphology and washing durability of loess dyed soybean fabric were investigated. The results obtained were as follows; Mean average diameter of loess was 1.08µm. The main components of loess used in this study were silicon dioxide(SiO₂), aluminium oxide(Al₂O₃), and iron oxide(Fe₂O₃). The content of these three component was above 75 weight %. The dyeability of soybean fabric was increased gradually with increasing concentration of loess. The optimum dyeing temperature and dyeing time were 90℃ and 60minutes expectively. The fastness to washing according to concentration of loess and mordanting method indicated good grade result as more than 4 degree in all conditions.

본 연구는 콩국수용 즉석 콩스프를 개발하기 위하여 콩스프 가공을 위한 최적 조건을 검토하였다. 콩스프 가공은 원료 침지, 증숙, 탈피, 건조, 분쇄, 제품포장의 순으로 하였다. 최적 콩 침지조건은 $25^{\circ}C$에서 4시간이었고, 이때 단백질의 함량은 노란콩 21.97%, 검정콩 19.88%이었다. 증숙처리시간이 길어짐에 따라 수분함량에는 큰 변화가 없었으며, 10$0^{\circ}C$에서 15분간 증숙처리한 것이 관능검사에서 가장 양호하였다. 열풍건조시 노란콩과 검정콩의 단백질 함량은 43.40~44.18%이었으나 원적외선 건조시는 44.59~51.36%로 높은 함량을 보였다. 증숙콩의 건조후 관능검사 결과, 노란콩과 검정콩 모두 원적외선 건조기로 45$^{\circ}C$에서 5시간 건조하였을 때 가장 좋았고, 시판용 콩국수와 본 제품과는 관능검사에서 차이가 없었다. 콩국수를 위한 즉석 콩스프의 최적 농도는 콩스프 분말 50g에 물 1L이었다.

Gelidium (G.) elegans is a red alga inhabiting intertidal areas of North East Asia. We examined anti-oxidative and anti-inflammatory effects of G. elegans, depending on drying and extraction conditions, by determining reactive oxygen species (ROS) and nitric oxide (NO) in 3T3-L1 and RAW 264.7 cells. Extraction yields of samples using hot air drying (HD) and far-infrared ray drying (FID) were significantly higher than those using natural air drying (ND). The 70% ethanol extracts showed the highest total phenol and flavonoid contents compared to other extracts (0, 30, and 50% ethanol) under tested drying conditions. The scavenging activity on 2,2-diphenyl- 1-picrylhydrazyl (DPPH) and nitrite correlated with total phenol or flavonoid content in the extracts. The greatest DPPH scavenging effect was observed in 70% ethanol extract from FID and HD conditions. The production of ROS and NO in 3T3-L1 and macrophage cells greatly decreased with the 70% ethanol extraction derived from FID. This study suggests that 70% ethanol extraction of G. elegans dried by FID is the most optimal condition to obtain efficiently antioxidant compounds of G. elegans.

In this paper, we investigated the electronic structures and defect states of $SrLaMgTaO_6$ (SLMTO) double perovskite structures by using resonant inelastic x-ray scattering. Recently, $Eu^{3+}$ doped SLMTO red phosphors have been vigorously investigated due to their higher red emission efficiency compared to commercial white light emitting diodes (W-LED). However, a comprehensive understanding on the electronic structures and defect states of host SLMTO compounds, which are specifically related to the W-LED and photoluminescence (PL), is far from complete. Here, we found that the PL spectra of SLMTO powder compounds sintered at a higher temperature, $1400^{\circ}C$, were weaker in the blue emission regions (at around 400 nm) and became enhanced in near infrared (NIR) regions compared to those sintered at $1200^{\circ}C$. To elucidate the difference of the PL spectra, we performed resonant inelastic x-ray spectroscopy (RIXS) at Ta L-edge. Our RIXS result implies that the microscopic origin of different PL spectra is not relevant to the Ta-related defects and oxygen vacancies.

In this paper, fabricated by MEMS uncooled micro-bolometer detector for the study in the infrared sensitivity enhancement. Absorption layer SiOx-Metal series MDTF (metal-dielectric thin film) by high absorption rate and has a high thermal coefficient of resistance, low noise characteristics were implemented. Then MDTF were made in a vacuum deposition method. And MDTF for the analysis of the physical properties of silicon wafers were fabricated, TCR (temperature coefficient of resistance) value was made in order to measure the glass wafer and FT-IR (Fourier Transform Infrared spectroscopy) values were made in order to measure the germanium window. The analyzed results of MDTF -3 [%/K] has more characteristics of the TCR. And 8~12 um wavelength region close to 70% in the absorption characteristic.
