This study was conducted to mass-produce brown stock optimized by using a high-pressure heating extractor and to use brown stock as a material for developing various products. For these purposes, we attempted to produce standardized brown stock by extracting brown stock using a high-pressure heating extractor and compared it with brown stock extracted by the traditional method in terms of general elements and mechanical and sensory characteristics. With regard to how to prepare optimal brown stock, the best brown stock was that extracted seven times repeatedly by the traditional method, but the method had a large economic loss in terms of material consumption and took a long time in extraction. Thus, considering time and labor, it was concluded that extraction at 120$^{\circ}C$ for 15 hours using a high-pressure heating extractor is the optimal extraction condition in terms of economic efficiency and quality. The results of this study are expected to be useful as a practical material for making brown stock production process more convenient, applying cooks' traditional cooking techniques to mass production, maintaining standardized superior quality and taste, and improving shelf life.

The influence of the yuza juice addition on quality of the doenjang was investigated by analyzing their chemical properties. The 80 days pre-fermented(PFD) and non-fermented(NFD) doenjangs used in the present study were mixed with yuza juice designed at different ratio (0, 1, 3, 5% (w/w)), These doenjangs were fermented for 60 days and then analyzed chemical properties, respectively. The moisture content was higher in yuza juice added groups than control group. But Ash, crude lipid and crude protein contents were higher in control than yuza juice added groups. The pH and formol-N were higher in yuza juice added NFD groups however, acidity was reversed. Among the free sugars, glucose contents was the highest. And, free sugars contents were higher in yuza juice added PFD groups than control group. Five kinds organic acids were detected, and succinic acid content was the highest. The organic acid contents were higher in proportion to adding volume of yuza juice, in all groups. The contents of Free amino acids were higher in yuza juice added PFD groups and among these, 1% yuza juice added PFD group(3970.0 mg%) was the highest. Hunter L value was lower by yuza juice added volume and higher in PFD groups. Hunter a and b values were non-significantly difference in PFD and NFD, respectively.

UNESCO Framework for the Culture Statistics(FCS) is composed of cultural media and cultural activities. It's structure has become a standard and criteria for cultural statistics of the nations in the world. In this paper $\ulcorner$Culture and Arts Statistics in Korea$\lrcorner$ and $\ulcorner$Culture and Arts Statistics of Developed Countries$\lrcorner$ has been analyzed based with FCS, in the respect of the structure and equality of the statistical items in cultural fields. The former has been published rationally through the steps of structural research, producing items and renew the structure, but the latter hasn't. The latter needs the policy to select the nations and research for the cultural structure to apply for them.

As a countermeasure under accidental occurrence situation, First, as application form of martial arts, A security guard foster ability that can protect a target person of guard and own body under accidental occurrence situation through incessant martial arts practice. To achieve this purpose, incessant training mental power and physical strength reinforcement should be kept on to prevent, therefore make a safety control function for such as weapon, small arms, explosive, vehicles terror etc. happened under accidental occurrence situation. Second, according to the contents of training based on the classification category of martial arts for security guard under accidental situation, a security guard must keep safety distance necessarily lest a target person of gurad should be attacked by attacker, therefore, intercept an attack opportunity if a safety distance between a target person of guard and attacker is not kept. Third, It is to practice confrontation techniques based on the type of attack. A security guard must develp situation disposal ability that can cope properly with the attack using empty hands, murderous weapon, small arms, explosive by case or individual or mass of threat that impose danger and injury in a target person's body of guard.

Postsurgical infections are caused by implant-related pathogenic microorganisms that lead to graft rejection. Hence, an intrinsically antibacterial material is required to produce a biocompatible biomaterial with osteogenic properties that could address this major issue. Hence, this current research aims to make strontium-doped hydroxyapatite nanorods (SrHANRs) via an ethylene diamine tetraacetic acid (EDTA)-enable microwave mediated method using Anodontia alba seashells for biomedical applications. This investigation also perceives that EDTA acts as a soft template to accomplish Sr-doping and mesoporous structures in pure hydroxyapatite nanorods (HANRs). The X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis reveals the crystalline and mesoporous structures, and Brunauer-Emmett-Teller (BET) indicates the surface area of all the samples, including pure HANRs and doped HANRs. In addition, the biocidal ability was tested using various implant-related infectious bacteria pathogens, and it was discovered that Sr-doped HANRs have excellent biocidal properties. Furthermore, toxicity evaluation using zebrafish reports the non-toxic nature of the produced HANRs. Incorporating Sr²⁺ ions into the HAp lattice would enhance biocompatibility, biocidal activity, and osteoconductive properties. As a result, the biocompatible HANRs materials synthesized with Sr-dopants may be effective in bone regeneration and antibacterial in-built implant applications.

In this paper, we show that for a semi-shift the analytic spectral subspace coincides with the algebraic spectral subspace. Using this result, we have the following result. Let T be a decomposable operator on a Banach space ${\mathcal{X}}$ and let S be a semi-shift on a Banach space ${\mathcal{Y}}$. Then every linear operator ${\theta}:{\mathcal{X}}{\rightarrow}{\mathcal{Y}}$ with $S{\theta}={\theta}T$ is necessarily continuous.

The crystals are triclinic, space group Pi and unit cell contains two formula units and has dimensions a = 4.54, b = 7.45, c = 7.76${\AA}$ and ${\alpha}$ = 102.5, ${\beta}$=93.6, ${\gamma}=78.7^{\circ}$. The present structure determination confirmed that the structure of monoethanolamine hydrobromide is isomorphous with that of monoethanolamine hydrochloride.

The production of nonwoven fabrics from natural fibers is already expanding at an industrial level for simple curvature semi-structural part in the automotive industry. To develop their use for technical applications, this paper provides an experimental study of the mechanical behavior of flax-fiber nonwoven preforms. A comparison between different sets of carded needle-punched nonwoven has been used to study the influence of manufacturing parameters such as fibers' directions, the area and the needle punching densities. We have found that the anisotropy observed between both directions can be reduced depending on these parameters. Furthermore, this work investigates the possibility to form double curvature parts such as a hemisphere as well as a more complex shape such as a square box which possesses four triple curvature points. We propose a forming process adapted to the features of the nonwoven structure. The purpose is to determine their behavior under high stress during various forming settings. The preforming tests allowed us to observe in real time the manufacturing defects as well as the high deformability potential of flax nonwoven.
