Cheese is a nutritious food with various balanced nutrients, such as proteins, peptides, amino acids, fats, fatty acids, vitamins and minerals. Domestic cheese varieties and quality need to be improved to prevent imported cheese. To develop those cheeses, search for previous works and research for new products are needed. In cheese ripening of hard cheese, such as Cheddar or Parmesan cheese, is ripened for 2 to 24 months at 2 to 16$^{\circ}C$ to develop desired cheese flavor and body characteristics. Long time with low temperature to ripen the cheese requires high expenses. So accelerated cheese ripening is a good potential for saving in industry. Methods for acceleration of cheese ripening are temperature control, addition of bacteria or enzymes. To develop the functionality of cheese, addition of microencapsulated various probiotics and nutrients, such as iron, removal of cholesterol by crosslinked ${\beta}$-cyclodextrin, lowering blood cholesterol and serum glucose by nanopowdered functional materials et al. are necessary. Therefore, this review focused on the functionality of cheese, such as the acceleration of cheese ripening, microencapsulated probiotics and iron, and cholesterol removal.

The dyeing properties of protein fiber with pine needles colorants were studied through an investigation of the effect of dyeing conditions such as dye concentration, dyeing temperatures and time on dye uptakes, effect of mordants, and color change. In addition, the various colorfastness of dyed silk and wool fabrics were evaluated for practical use. The antimicrobial ability, ultraviolet-cut ability, and deodorant ability were also estimated. The dye uptake increased as the dyeing concentration increased and this enabled the obtainment of the Langmuir absorption isotherm. The dye uptake increased as the dyeing time and temperature increased. Pine needles colorants showed relatively good affinity to protein fiber and produced a yellow color. Post-mordanting was more effective than the pre-mordanting, and the dye uptake of fabrics improved by mordanting. Except for washing, the colorfastness of dyed fabrics showed a low rating. However, the colorfastness to light and the dry cleaning of fabrics mordanted with N.Cu, and the friction fastness of fabrics mordanted with Cu improved. The guide fabrics showed very good antimicrobial abilities of 99.9%; in addition, the ultraviolet-cut ability and deodorant ability improved in fabrics dyed with pine needles extracts.

BACKGROUND/OBJECTIVES: High levels of plasma low-density lipoprotein (LDL) cholesterol are an important determinant of atherosclerotic lesion formation. The disruption of cholesterol efflux or reverse cholesterol transport (RCT) in peripheral tissues and macrophages may promote atherogenesis. The aim of the current study was to examine whether bioactive ellagic acid, a functional food component, improved RCT functionality and high-density lipoprotein (HDL) function in diet-induced atherogenesis of apolipoproteins E (apoE) knockout (KO) mice. MATERIALS/METHODS: Wild type mice and apoE KO mice were fed a high-cholesterol Paigen diet for 10 weeks to induce hypercholesterolemia and atherosclerosis, and concomitantly received 10 mg/kg ellagic acid via gavage. RESULTS: Supplying ellagic acid enhanced induction of apoE and ATP-binding cassette (ABC) transporter G1 in oxidized LDL-exposed macrophages, facilitating cholesterol efflux associated with RCT. Oral administration of ellagic acid to apoE KO mice fed on Paigen diet improved hypercholesterolemia with reduced atherogenic index. This compound enhanced the expression of ABC transporters in peritoneal macrophages isolated from apoE KO mice fed on Paigen diet, indicating increased cholesterol efflux. Plasma levels of cholesterol ester transport protein and phospholipid transport protein involved in RCT were elevated in mice lack of apoE gene, which was substantially reduced by supplementing ellagic acid to Paigen diet-fed mice. In addition, ellagic acid attenuated hepatic lipid accumulation in apoE KO mice, evidenced by staining of hematoxylin and eosin and oil red O. Furthermore, the supplementation of 10 mg/kg ellagic acid favorably influenced the transcriptional levels of hepatic LDL receptor and scavenger receptor-B1 in Paigen diet-fed apoE KO mice. CONCLUSION: Ellagic acid may be an athero-protective dietary compound encumbering diet-induced atherogenesis though improving the RCT functionality.
Objective: In patients with temporomandibular joint disorders, air insoles are used to investigate functionality and pain changes in the temporomandibular joint when walking in daily life. Intervention: Sixty-five patients with temporomandibular joint disorder were recruited: 34 as a control group who walked more than 7,000 steps a day in daily life, and 31 as an experimental group who were instructed to take at least 7,000 steps every day while wearing their air insoles. Measurements: To determine the effects of air insoles on temporomandibular joint pain, steady-state pain, maximum mouth opening, average pain, and the most severe pain were measured before and after the experiment. In addition, to evaluate functionality, the ability to open the mouth in a comfortable state, pain when opening the mouth, and the point of sound and maximum degree to which the mouth could be opened were evaluated before and after the experiment. Results: Pain, mouth openness, and sound points showed significant differences from the control group after the experiment, and the maximum mouth opening range showed no significant difference. Conclusion: When air insoles were used by patients with temporomandibular joint disorder, the functionality of the temporomandibular joint was improved and pain was decreased.
The purpose of this study was to examine the current satisfaction levels with nurse uniforms at Taizhou General Hospital in China and to find areas for improvement in order to develop nurse uniforms with improved comfort, fit and convenience. To investigate satisfaction with nurse uniforms, a survey was conducted of 150 nurses. The general characteristics of the nurses, uniform conditions, feelings of satisfaction, fit, preferred designs, inconvenient aspects of the uniforms, and areas for improvement were analyzed. Eight materials of cotton/polyester blended fabrics were selected according to Chinese nurse uniform regulations, and the physical properties of the materials were tested along with the materials used in current nurse uniforms. Four new nurse uniforms with increased aesthetics, functionality, and comfort were developed based on the survey results. Materials with excellent absorption, moisture permeability, and ventilation were used as main fabrics. According to the preferred designs of nurses at Taizhou City General Hospital, China, 4 types of nurse uniforms designed, consisting of design 1 (shirt and pants), design 2 (shirt and pants), design 3 (dress), and design 4 (shirt and skirt). The new nurse uniforms offered better functionality with an improved fit at the armpits, waist, hips, and knees based on product measurements.

The development of lightweight, low energy and small-sized sensors incorporated with the wireless networks has brought about a phenomenal growth of Wireless Sensor Networks (WSNs) in its different fields of applications. Moreover, the routing of data is crucial in a wide number of critical applications that includes ecosystem monitoring, military and disaster management. However, the time-delay, energy imbalance and minimized network lifetime are considered as the key problems faced during the process of data transmission. Furthermore, only when the functionality of cluster head selection is available in WSNs, it is possible to improve energy and network lifetime. Besides that, the task of cluster head selection is regarded as an NP-hard optimization problem that can be effectively modelled using hybrid metaheuristic approaches. Due to this reason, an Improved Coyote Optimization Algorithm-based Clustering Technique (ICOACT) is proposed for extending the lifetime for making efficient choices for cluster heads while maintaining a consistent balance between exploitation and exploration. The issue of premature convergence and its tendency of being trapped into the local optima in the Improved Coyote Optimization Algorithm (ICOA) through the selection of center solution is used for replacing the best solution in the search space during the clustering functionality. The simulation results of the proposed ICOACT confirmed its efficiency by increasing the number of alive nodes, the total number of clusters formed with the least amount of end-to-end delay and mean packet loss rate.
A questionnaire survey of farmers engaged in actual farming was conducted to investigate the farmers' actual wearing conditions and preferences for agricultural workwear to develop workwear that is suitable for improved agricultural work efficiency. We extracted basic data necessary for the development of agricultural workwear. Analysis of the photographs taken showed differences in the shoes and gloves worn depending on the type of work. The percentages of men and women were equal among the agricultural workers. The age of the agricultural workers was analyzed and the results showed a higher percentage of those over 50 years old, indicating that the age of the agricultural workers was higher than in other industries. It was found that the waist, knees, and elbows of the workers were pulled during work, and analysis showed that the symptoms resulting from clothing pulling were more severe when the wearing dimensions were larger. It was recognized that the important aspects of workwear are those related to work, such as functionality, activity, and work efficiency. In addition to workwear, the most commonly worn auxiliary equipment was gloves, and other items included hats, armbands, work shoes, boots, seat chairs, and masks. When developing rural workwear, it is necessary to consider the fit, type of work, and materials of the workwear. Future research should focus on materials that can improve the functionality of workwear and pattern development that reflects physical and movement characteristics.
This study investigated the properties and functions of wool and silk dyed with Catechu by examining the effects of dying conditions such as dye concentration, dying temperature, dyeing time, pH level and pre-mordants. These conditions were examined in relation to dye uptake and color changes, washing fastness, light fastness, ultraviolet-cut ability and antimicrobial ability of the dyed fabrics. Catechu showed good affinity to silk fiber. Langmuir adsorption isotherm was obtained, and so it was considered that ionic bondings are formed between Catechu and protein fiber. As the dyeing time and temperature is increased, the dyeability of both silk and wool fabrics also increases. At high temperatures the color of dyed fabrics changes from Y and YR to R. Wool is effective in using Al, Cu, Fe mordant, while silk is effective only in using only Cu mordants. The dyeability was shown to be improved at low pH levels. Additionally, both washing fastness and light fastness were shown to be low. However, the fabric color gradually changed to red was due to mailard reaction of catechol tannin causingby repeated washing and sunlight. The ultraviolet-cut ability was improved for cotton fabric dyed with Catechu. Also, dyed fabric with Catechu showed very good antimicrobial abilities at 99.9%.
