Kaolin has long been used in aqueous coatings to produce high-quality coated paper products. While the kaolin industry hat always focused on innovation. the rate of new product introduction hat never been greater than in the past five-to-eight years due to the cost, quality and other competitive pressure facing papermakers. After summarizing many of the performance benefits offered by the new generation of kaolin-baled pigments. this paper reviews four specific pigment advances: a high-performance. ultrafine glossing pigment; an engineered pigment with a narrow particle size distribution; two products from a kaolin-based pigment family developed for metered size presses ; and a novel class of inkjet pigments.

In this paper, the notions of strong Connes amenability for certain products of Banach algebras and module extension of dual Banach algebras is investigated. We characterize χ ⊗ η-strong Connes amenability of projective tensor product ${\mathbb{K}}{\hat{\bigotimes}}{\mathbb{H}}$ via χ ⊗ η-σwc virtual diagonals, where χ ∈ 𝕂_* and η ∈ ℍ_* are linear functionals on dual Banach algebras 𝕂 and ℍ, respectively. Also, we present some conditions for the existence of (χ, θ)-σwc virtual diagonals in the θ-Lau product of 𝕂 ×_θ ℍ. Finally, we characterize the notion of (χ, 0)-strong Connes amenability for module extension of dual Banach algebras 𝕂 ⊕ 𝕏, where 𝕏 is a normal Banach 𝕂-bimodule.

Let C[0, T] denote the space of continuous real-valued functions on [0, T]. On the space C[0, T], we introduce a Banach algebra of series of functions which are generalized Fourier-Stieltjes transforms of measures of finite variation on the product of simplex and Euclidean space. We evaluate analytic Feynman integrals of the functions in the Banach algebra which play significant roles in the Feynman integration theory and quantum mechanics.

현대 시장의 경향은 '기업은 제품을 팔고 소비자는 브랜드를 산다'라는 브랜드 전략을 나타내고 있다. 브랜드는 소비자의 요구와 경험을 반영하고 연출하는 제품과 소비자를 연결시키는 매개체로 작용한다. 성공적인 브랜드는 경험적인 미학적 전략을 지향하게 되었고, 소비자는 브랜드를 색다른 경험으로 인식하고 하나의 고정된 관념(인식)으로 떠올리게 된다. 많은 기업들은 막대한 홍보와 광고비용을 절감하는 최소의 투자비용으로 최대의 효과를 얻고자 한다. 구매시점에서 소비자와의 직접적 대면을 통해 제품 브랜드에 대한 인상을 각인시키고, 구매를 유도하는 기능을 하며 그 중요성이 날로 커지고 있다. 따라서 브랜드 이미지의 시각표현은 브랜드와 밀접하게 연결되어 소비자의 마음에 고정된 하나의 인상을 형성할 수 있어야 한다. 일단 긍정적인 인상으로 자리잡은 브랜드는 소비자의 기억으로 인출되어 별다른 정보 없이 브랜드만으로 구매에 이를 수 있게 한다. 이를 위한 시각적 표현의 해결은 브랜드 이미지의 핵심적 요소로서 브랜드의 로고 및 마크를 중심으로 한 시각화이며, 이를 뒷받침하는 커뮤니케이션 요인이라 하겠다. 이는 제품과 관련이 깊은 방향으로서의 디자인적 방향성을 가지게 될 뿐 아니라 브랜드의 언어적 특성과 그 연상성에 기반을 둔 시각 언어적인 의미 전이의 방법들로 문제해결을 위한 방법을 제시해 줄 수 있다. 따라서 본 연구에서는 시장경제를 형성하는 스포츠용품의 브랜드 이미지분석과 소비자 제품구매와의 관계를 이론 적 고찰하여 이를 효과적이고 일관성 있는 이미지를 형성하는 방향을 제시하는데 그 목적이 있다.

Fashion magazine advertising is the most excellent source of information in predicting the fashion trend. It plays a pivotal role in setting a direction for the fashion trend in the upcoming season. The purpose of this study was to review by photos of the $pr{\hat{e}}t-{\acute{a}}-porter$ collection shown in LONDON, NEW YORK, MILAN, and PARIS during 2002-2006 A/W and 2003-2005 S/S seasons, being focused on such fashion items published as coat, dress, one-piece, two-pieces(jacket+skirt/pants, blouse+skirt/pants). In the results of this study, designers presented coat(n=144) chiefly, blouse+pants(n=29) were presented few during 2002-2003 A/W seasons. During 2003-2004 A/W seasons one-piece(n=156) was looking bullish, blouse+pants(n=34) were declining. Dress(n=149) was presented mostly, blouse+pants(n=17) was presented few during 2004-2005 A/W seasons. During 2005-2006 A/W seasons coat(n=180) was revived, blouse+pants(n=26) were presented lowly. Therefore designers presented coat(n=605, 28.4%) extremely much during 2002-2006 A/W seasons. Designers presented one-piece(n=109) much, jacket+pants(n=22) were presented few in 2003 S/S. In 2004 S/S seasons one-piece(n=167) was presented vastly different than jacket+pants(n=42). Also one-piece(n=152) was presented mostly, blouse+pants(n=48) was presented few in 2005 S/S seasons. During 2003-2005 S/S seasons one-piece(n=428, 28.2%) was presented most. And designers in these four world fashion centers didn't prefer blouse+pants in A/W seasons and jacket+pants in S/S seasons. Based on the above findings, it could be confirmed that the fashion items trend was almost similar among the four collections of $pr{\hat{e}}t-{\acute{a}}-porter$. The results of this study suggest that the fashion collections are the most reliable information sources for fashion product planning. Lastly, it is hoped that this study will provide for some useful basic data for domestic fashion businesses in producing fashion items.

It is well-known that the spectrum of a $spin^{\mathbb{C}}$ Dirac operator on a closed Riemannian $spin^{\mathbb{C}}$ manifold $M^{2k}$ of dimension 2k for $k{\in}{\mathbb{N}}$ is symmetric. In this article, we prove that over an odd-dimensional Riemannian product $M^{2p}_1{\times}M^{2q+1}_2$ with a product $spin^{\mathbb{C}}$ structure for $p{\geq}1$, $q{\geq}0$, the spectrum of a $spin^{\mathbb{C}}$ Dirac operator given by a product connection is symmetric if and only if either the $spin^{\mathbb{C}}$ Dirac spectrum of $M^{2q+1}_2$ is symmetric or $(e^{{\frac{1}{2}}c_1(L_1)}{\hat{A}}(M_1))[M_1]=0$, where $L_1$ is the associated line bundle for the given $spin^{\mathbb{C}}$ structure of $M_1$.

The roll-forming process is a highly productive incremental forming process and is suitable for manufacturing thin, high-strength steel products. Recently, this process has been considered one of the most productive processes in manufacturing high-strength steel automotive structural parts. However, it is very difficult to develop the roll-forming process when the cross-sectional shape of the product changes in the longitudinal direction. In this study, a roll-forming process for manufacturing high-strength steel automotive parts with a linearly variable symmetric hat-type cross-section was developed. The forming rolls were designed by the 3D CAD system, CATIA. Additionally, the designed forming rolls were modified by the simulation through the 3D elastic-plastic finite element analysis software, MARC. The results of the finite element analysis show that the final roll-forming roll can successfully produce the desired high-strength steel automotive part with a variable cross-section.

This study develops a wearable solar energy harvesting device that absorbs solar energy to generate and store power which can be used during outdoor activities by users even after dark. For this study, a prototype hat for outdoor activities at night was developed after the design of a solar energy harvesting generation, storage, and delivery system was designed that could store energy to light up LEDs. First, the main control board of the system was designed to integrate the charging function, the darkness detection circuit, the battery voltage sensing circuit, and the LED driving circuit in order to reduce bulkiness and minimize the connection structure. It was designed to increase convenience. Second, the system was designed as a wearable fashion product that connected each part with fiber bands and manufacturing it so as to be detachable from the hat. Third, charging and LED operation tests show that the battery is fully charged after 5 hours even in winter when the illuminance value is low. In addition, the LED operation experiment verified the effectiveness of a buffered system that could operate the LEDs for about 3 hours at night.

This study was used samples, mackerel (Scomber japonicas), Japanese Spanish mackerel (Scomberomorus niphonius), alaska pollock (Theragra chalcogramma), yellow croaker (larimichthys crocea) known as some of the major species fisheries products in Korea We were investigated temperature change during thawing processing, water holding capacity, drip loss, extractive-nitrogen and viable cell count by various thawing methods, thawing at the room temperature (TRT), hot-air thawing (HAT), aeration thawing (AT), high-frequency thawing (HFT). The temperature changes have taken 2~3 hours in HFT and 24 hours by TRT. The expressible drip loss was 0.47~0.87 g/100 g in HFT, 1.91~4.42 g/100g in TRT, 1.31~4.93 g/100g in HAT, and 2.01~4.59 g/100g in AE. The water holding capacity was higher samples thawing by HFT than other thawing methods. Extractive-nitrogen was 276~452 mg/100 g in HFT, 177.21~420.27 mg/100 g in TRT. Viable cell count was $10^2$ to $10^3$ in HFT, $10^3$ to $10^5$ in other thawing methods. The processing speed and uniformity by HFT was minimized the risk of product degradations (drip losses, deterioration of sensorial, chemical and physical characteristics, bacteria growth, etc.), thus helping to preserve at its best the product quality than those by thawing methods. Therefore, HFT was expected to make high-quality thawing products anticipate future thawing technology

Open reading frame 29 (ha29) is a gene specific for Helicoverpa armigera single-nucleocapsid nucleopolyhedrovirus (HearSNPV). Sequence analyses showed that the transcription factor Tfb2 motif, bromodomain and Half-A-TPR (HAT) repeat were present at aa 66-82, 4-76, 55-90 of the Ha29 protein respectively. The product of Ha29 was detected in HearSNPV-infected HzAM1 cells at 3 h post-infection. Western blot analysis using a polyclonal antibody produced by immunizing a rabbit with purified GST-Ha29 fusion protein indicates that Ha29 is an early gene. The size of Ha29 product in infected HzAM1 cells was about 25 kDa, which was larger than the presumed size of 20.4 kDa. Tunicamycin treatment of HearSNPV-infected HzAM1 cells suggested that the Ha29 protein is N-glycosylated. Fluorescent confocal laser scanning microscope examination, and Western blot analysis of purified budded virus (BVs), occlusion-derived virus (ODVs), cell nuclear and cytoplasmic fraction, showed that the Ha29 protein was localized in the nucleus. Our results suggested that ha29 of HearSNPV encodes a non-structurally functional protein that may be associated with virus gene transcription in Helicoverpa hosts.
