Split-type nylon/polyester microfiber and polyester microfiber fabrics possess drapeability, softness, bulkiness, and smoothness, so that they can be applied in various industrial fields. In particular, these fabrics are able to absorb various organic solvents, and can be used as clean room materials. To investigate the chemical affinity between solvents and the compositional materials of these fabrics, the contact angle of thermally pressed film fabrics was measured with different solvents. The thermally pressed nylon/polyester fabric films showed a chemical attraction to formamide. The sorption properties of the microfiber fabrics were investigated using a real time testing device, and these tests showed that the sorption behavior was more influenced by the structure of the fibrous assembly than by any chemical attraction. The effect of the fabric density, specific weight, and sample structure on the sorption capacity and rate was examined for various organic solvents. The sorption capacity was influenced by the density and the specific weight of the fibrous assembly, and knitted fabric showed a higher sorption capacity than woven fabric. However, the sorption rate was less affected in lower viscosity solvents. On applying Poiseuille's Law, the lower viscosity solvents showed higher initial sorption rates, and more easily penetrated into the fibrous assembly.
The objective of the study is to understand the characteristics of modernistic spatial design and, based on the understanding, to interpret fashion in terms of its spatial relationship with society, culture and human body, thereby looking into unique spatial characteristics fashion has. The main results of this study include : First, the rational space emphasizes geometric symmetry and harmony among each of design elements and is expressed by pursuing a perfect formative beauty that indicates an eternal formal beauty of a physical space. In addition, functional beauty is also pursued, making clothing convenient for activities. Second, the abstract space is characterized as a kind of purity by emphasizing simple patterns and colors and materials of purity for clothing, and it is sometimes expressed as being extremely abstract so that human body can be shown to be distorted. Third, for the uniform and neutral space, mass-production and production at home was made possible with clothing of simple patterns and of standard. In addition, it showed a tendency to become blurred in gender distinction for clothing with women wearing men's clothing, or borrowing design elements from men's clothing. Forth, the space as means of domination and control was shown to be segmented based on place, function and purpose. In addition, control on physical beauty was shown by promoting slim figures that are suited for lineal silhouette of clothing and circumstantial restriction on clothing occurred during war, serving to limit the styles of and purchase of clothing.
Recent advances in Internet-of-Things and wearable computing have established computationally sufficient infrastructure to remove the barriers of physical locations. The recent COVID-19 pandemic has accelerated the use of remote collaboration, work-from-home, teleconferencing, online education, digital twin, and metaverse enriched with various configurations of augmented reality, virtual reality, mixed reality, and extended reality. Beyond specialized niche wearable applications in the medical and entertainment domains, we aim to identify the underlying characteristics of smartglass-enabled killer applications for everyday use. In this paper, we analyze intermediary roles in remote collaboration consisting of authoritative supervisors, synergetic collaborators, and speculative explorers. We also propose technical components for smartglass-assisted interactive remote collaboration composed of personal tracking, teleconference, and interaction components. More specifically, the application tasks of each intermediary role and objectives of three functional components are defined and elaborated.
A Study on the color comparison of Korean Saek-dong and Italian futurist fashion It is generally recognized that the color scheme and its characteristics as a product of living culture are strongly reflected in clothing. This study concentrates on the color comparison of Korean Saek-dong which has been used in traditional Korean clothing and Italian futurist fashion which showed dynamic characteristics and brilliant colors. The purpose of this study is to investigate the external format, emotions, functions and meanings of the colors in Korean Saek-dong and Futurist fashion, and to find similarities and differences between them. The results of the study are as follows. The similarities between them are harmony of vivid colors like a rainbow, no-use of black color and expression of rhythm through repeated geometrical shapes. They have been used as festive costumes and have implied meaning of happiness and pleasure. The differences, in the external formats, are as follows. Korean Saek-dong has striped patterns including the color white, and has regular distances among the stripes. But, Futurist fashion includes luminous or fluorescent colors and metallic colors. In addition, it has repeated motifs of geometrical shapes and geometrically divided areas. While Saek-dong expresses Sangsaeng through the conceptual use of color, Futurist fashion shows simultaneity, speed and dynamics through spiritual functions of crossing and inter-penetration. In emotional aspect, Saek-dong expresses pleasure of children's mind and Futurist fashion expresses pleasure of city. In functional aspect, Saek-dons expresses a concept of ceremonial beauty, which is spiritual and symbolizes good auspices, holiness and sorcery. So it is used for ceremonial costume. But, Futurist fashion reflects the harmony of colors created from modem and urban images and shows the willingness and emotion of solving futuristic avant-garde, modernity, dynamics, transformation and bellicosity. So it is used for daywear. While Saek-dong represents succession of tradition, Futurist fashion represents resistance of tradition in cultural aspects.
The principal objective of was to assess the effects of herb extracts on the antioxidant activity and quality characteristics of Maejakgwa. The total phenolic and flavonoid contents were found to be the highest by a significant degree in the rosemary, lavender, thyme, lemon balm and olive samples, in order. With regard to electron donating ability, increasing concentrations of added herbs resulted in a more significant rise in the DPPH radical scavenging effect in a range of concentrations of between $100{\sim}1000{\mu}g/m{\ell}$. In particular, the rosemary, lavender, and thyme samples were shown to be lower in antioxidant activity than ascorbic acid, but higher than a-tocopherol, thus the antioxidant activities detected in the rosemary, lavender, and thyme samples were considered to be excellent. With regard to reducing ability, increases in the concentration of added herb extract resulted in significant growth. However, the anti-oxidative activity detected in the rosemary extract was indicated to be superior even to that of $\alpha$-tocopherol when added to concentrations of $500{\sim}1,000{\mu}g/m{\ell}$. In our assessment of external appearance, color, flavor, texture, and overall quality, the highest preference was seen in the control group and in the group with 2% added rosemary extract. The lowest score was earned in the group with a 5% addition of rosemary. The functional ingredients and antioxidant activities of the samples were excellent. Our results appear to indicate that rosemary has some value as a natural antioxidant that can prevent oxidation in food.
Purpose: This study, using the International Classification for Nursing Practice, aimed to identify the phenomenon of family nursing care, and the factors affecting it, for high-risk and frail older persons who have a significant need for home healthcare services. Methods: This study was conducted using secondary data collected by students who interviewed 93 healthcare subjects in a health center. The data was used to analyze the general characteristics, health-related characteristics, and confirmed problems of family nursing phenomena of the subjects. Independant t-test, Pearson correlation coefficient, and multiple linear regression were used for the data analysis. Results: The mean age of the subjects was 82.4±6.3 years. The most common problem of the family nursing phenomenon were unhealthy lifestyle, disturbance in family communication, and lack of family interaction in the community. People with greater family nursing phenomenon problems reported a higher degree of frailty and depression, lower quality of life and self-rated health. The factors that influence the family nursing phenomenon of frail older persons are the problems of mobility and hearing. Conclusion: Physical and psychological problems associated with aging can cause not only personal, but family functional problems as well. Therefore, a comprehensive family-oriented support program is required.
Background: Little data is available regarding hospitalized patients with nursing home-acquired pneumonia (NHAP). This is unfortunate because there is an increasing number of elderly persons who are living in nursing homes in Korea. The aim of this study was to compare clinical characteristics and treatment responses of NHAP with community-acquired pneumonia (CAP). Methods: Patients with pneumonia who were admitted from eight nursing homes or from their own homes were enrolled between May 2007 and April 2009. Their clinical characteristics and treatment responses were reviewed retrospectively, and differences between the two groups were analyzed. Results: Of 110 Patients with pneumonia, 66 (60%) were from nursing homes and their median age was 84. In the NHAP group, functional performance status was significantly poorer, classical symptoms of pneumonia were less severe, and multi-lobe involvement (on chest radiographs) was more frequent than in the CAP group. Patients with NHAP more frequently showed lymphocytopenia, anemia, hypoalbuminemia, hypoxemia, and elevated blood urea nitrogen on admission. The mean CURB-65 score was 2.2 in the NHAP group, higher than 1.7 in the CAP group (p=0.004), and multi-drug resistant pathogens were also highly identified in NHAP group (39% vs. 10%, p=0.036). The mean duration of antibiotic therapy was greater for the NHAP (12.6 days) than for the CAP group (6.6 days) (p<0.001). The mortality rate was 23% in NHAP group, which was significantly higher than 5% in the CAP group (p=0.014). Conclusion: NHAP should be more intensively investigated because of the higher frequency of multi-drug resistant pathogens and mortality than the CAP.
Opuntia cactus grows in the southern part of Korea, Geoje Island, Jeju Island, and South Coast. The flowers bloom around April to May of each year, and purple berries ripen around November to December. It has been widely used in home medicine since ancient times and it has great effects on blood circulation, detoxification, analgesia and antioxidant activity. In this study, we tried to demonstrate antioxidant, antidiabetic and antimicrobial activities of Opuntia monacantha Haw., and also grasp the value as a functional raw material. As a result, a strong antioxidative effect was confirmed by extracting taxifolin which is an antioxidative substance in Opuntia monacantha Haw. In the antidiabetic function test, a high level of antidiabetic function was confirmed when compared to that of using a commercially available diabetic drug. In addition, as a result of the antimicrobial effect measurement, it showed a strong antimicrobial activity on E.coli and Salmonella, and proved the excellent value of Opuntia manacantha Haw. as a functional ingredient.

D/H=1>Hyangkyo>houses on the river>lecture halls. 4. Inner garden were planted deciduous than evergreen trees with Lagerstroemia indica. Enclosed dominant trees were planted by Pinus densiflora, Querces seuata.construct GEM strain, and examined for the expression and functional stability in microcosms.
The purpose of this study was to identify the types of social networks of urban housewives according to different network composition patterns and to analyze the structural and functional characteristics of identified types. The data used in this study were collected from 589 full-time housewives residing in Taejeon city. The major findings are as follows: 1) The social networks of housewives in urban nuclear families were classified into eight types: the kin network, the non-kin network, the kin-centered network, the friend-centered network, the neighbor-centered network, the associate-centered network, the parallel network, and the decentralized network. 2) The structual characteristics (size, density, homogeneity, duration, proximity, frequency, closeness, direction) varied according to the type. The kin network type and the non-kin network type showed extreme degrees in network characteristics. The parallel network type and the decentralized network type showed an average level of network characteristics. The kin-, friend-, neighbor-, and the associate-centered types showed network characteristics of an intermediate level between the single-category types and the decentralized type. 3) The average levels of function of social network types were different in only two(service support, interference) of the six function areas(emotional support, service support, material support, information support, social companionship support, interference). The average level of service support by the non-kin network type was higher than other types. The average level of interference by the kin-centered network type was higher than other types, and that of the neighbor-centered network type was lower than other types. On the other hand, the total amount of function performance of social network types was different in all function areas. The total amount of social support given by the decentralized network type was greater than the other types. The total amount of interference given by the non-kin network type was smaller than the other types.
