The purpose of this study is to examine the characteristics of Arne Jacobsen's chair design. He was one of the few creators who inscribed his name in both the history of architecture and furniture design. His works reflected a form of "Regional Modernism" in which traditional techniques collide with functionalist beliefs. This grafting of ideas generated a person aesthetics which he used to establish a suitability of scale, detail an program for each design. In the material aspect, he had enjoyed using the plasticity of the plywood, polyurethane, tubular steel and in the formative aspect, organic form is combined with minimalization of material and simplicity. To sum up what is unique about Arne Jacobsen's chair design, it is that it is distinguished by a clear understanding and expression of beauty from nature, a complete understanding of the material used and the melding of traditional and functional techniques to generate organic form.anic form.

Due to the broad host suitability of viral vectors and their high gene delivery capacity, many researchers are focusing on viral vector-mediated gene therapy. Among the retroviruses, foamy viruses have been considered potential gene therapy vectors because of their non-pathogenicity. To date, the prototype foamy virus is the only retrovirus that has a high-resolution structure of intasomes, nucleoprotein complexes formed by integrase, and viral DNA. The integration of viral DNA into the host chromosome is an essential step for viral vector development. This process is mediated by virally encoded integrase, which catalyzes unique chemical reactions. Additionally, recent studies on foamy virus integrase elucidated the catalytic functions of its three distinct domains and their effect on viral pathogenicity. This review focuses on recent advancements in biochemical, structural, and functional studies of foamy virus integrase for gene therapy vector research.

This study was conducted to develop a basic pants pattern reflecting the average body shape of Chinese women in their 20s by using a virtual fitting method. A formula for the research pattern was derived by applying the measured value based on the drafting method of existing patterns. The final pattern was presented through two actual fitting processes. The suitability of the final pattern was then verified through a functional evaluation and an appearance evaluation based on an actual fitting and a virtual fitting. As a result of the evaluations, the final pattern reflected the body shape of Chinese women in their 20s and was evaluated as a higher quality pattern compared to existing patterns. The final pattern was based on the omphalion waist circumference. Ease amounts were set to be the omphalion waist circumference + 1.0 cm, hip circumference + 2.0 cm, and the pants length was set to 94 cm.

Purpose: This study was aimed to compare the nutritional content of the life stages of Tenebrio molitor. Methods: Nutritional element analysis comprised 12 minerals, 18 amino acids, 4 vitamins, and 12 fatty acids in larval, pupal, and adult stages. Nutritional element content was expressed as a percentage of 100 g of sample and determined in raw and freeze-dried samples to assess the food value of the insect. Results: Moisture, crude protein, and crude fat contents in raw samples were 63.5%, 23.19%, and 3.96%, respectively. Moisture content was significantly higher in the adult stage than in larval and pupal stages, whereas crude fat and crude ash contents were lower. Mineral composition of the mealworm showed K, P, and Mg in decreasing order of content, with no differences among life stages. Total amino acid content increased from adult, pupal to larval stages, in order with each stage's growth, without difference in amino acid composition. Seventy-six to 78% of total fatty acid corresponded to unsaturated fatty acids, with oleic acid as the most abundant. In addition, fatty acid content was high in the adult stage, and clear differences were observed between life stages. Finally, vitamins B1 and B3 showed similar content between life stages, whereas vitamin B2 showed a higher content the adult than larval and pupal stages. A higher folate content was observed in pupal and adult stages than in the larval stage. Although freeze-dried samples showed a higher nutritional content than raw samples, both samples were similar in composition and content between life stages, suggesting the suitability of freeze-dried samples for use as food materials. Conclusion: These results may provide a basis for more diversified industrial applications of the Tenebrio molitor.

The purpose of this study is to select indicators by a methodical approach and to establish a functional assessment system as a basic study for planning and constructing green space of forest. The types of green space were divided into 6 classes based on theoretical reviews of literature and the functions of green space were restricted to 'nature-ecological function', 'environment-control function' and 'usage function'. As a result of the selection of indicators, 35 indicators were initially selected by theoretical review and these indicators were reduced to 29 through brainstorming. Also, these indicators were classified into three functions such as 12 indicators (nature-ecological function), 8 indicators (environment-control function), 6 indicators (usage function) by analysis of suitability. According to the result of selection of the optimum indicators using MCB (Multiple Comparisons with the Best treatment) analysis, the optimum indicators of 7, 5, and 4 respectively by each function were selected for forest green space. The results of AHP (Analytic Hierarchy Process) for the establishment of the assessment system in forest, the weight of nature-ecological function was evaluated highest at 0.558, while the weight of environment-control and usage function were calculated at each 0.277, 0.165. 'Naturality (0.189)', 'Carbon sink (0.235)', and 'Accessibility (0.354)' among indicators showed highest by each function. The weight of indicator and assessment system may be used as a valuable guideline in case of assessing synthetically green space within urban planning.

In India, nanotechnology has been used in therapeutic applications for several millennia. One example of a traditional nanomedicine is Rajath Bhasma (also called calcined silver ash), which is used as an antimicrobial and for the treatment of various ailments and conditions such as memory loss, eye diseases, and dehydration. In this study, we aimed to characterize the physical composition and morphology of Rajath Bhasma and its suitability for use as a non-toxic antimicrobial agent. First, Rajath Bhasma was physically characterized via i) Fourier-transform infrared spectroscopy to analyze the surface functional groups, ii) scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy to observe the morphology and elemental composition, and iii) X-ray diffraction to determine the crystalline phases. Thereafter, functional characterization was performed through toxicity screening using zebrafish embryos and through antimicrobial activity assessment against gram-positive (Staphylococcus epidermidis) and gram-negative (Escherichia coli) bacteria. Rajath Bhasma was found to harbor alkene, hydroxyl, aldehyde, and amide functional groups originating from biological components on its surface. The main component of Rajath Bhasma is silver, with particle size of 170-210 nm, and existing in the form of spherical aggregates with pure crystalline silver structures. Furthermore, Rajath Bhasma did not exert toxic effects on zebrafish embryos at concentrations below 5 ㎍/ml and exhibited effective antimicrobial activity against both gram-positive and gram-negative bacteria. The present results indicate that Rajath Bhasma is a potentially effective antimicrobial agent without toxicity when used at concentrations below 5 ㎍/ml.

This research developed maternity wear designed with a focus on the essential functions necessary for working women and adaptable to their body changes during pregnancy. Through Martin's anthropometry for 201 pregnant women, the size specifications for maternity wear was determined and a dress form was proposed, in order to provide the manufacturer with reference data and a prototype to verify their products' fit and suitability. From a monthly analysis on the body measurements of pregnant women, significant monthly differences and after pregnancy were found in weight, chest girth, bust girth, under bust girth, waist girth, and hip girth. Dress form was designed based on the average body measurements of women in their 6th to 10th month of pregnancy. The standard dimensions in the 8th month were 90cm (chest), 94cm (bust), 86cm (under bust), 97cm(waist: most protruding part on the side), and 99cm (hip). Compared with Japan's MAT-9 (for nine months), chest girth was the same, while the Korean waist girth and hip girth were larger by 2cm and 3cm, respectively. The woven fabric blouse was evaluated as having the best appearance, while the knitted fabric one was judged as being more comfortable it terms of functionality. For the pants, the design details of the lowered waist and curved waist belt were more functional. The tailored jacket was the best design for working women in terms of both looks and functionality. To summarize, maternity wear for working women, unlike general maternity clothes, should be designed with consideration for the wearer's somatotype and activity. Elastic materials were appropriate for functionality and dealing with physical changes. With the increasing of working pregnant women, such trials are expected to continue in this research area in order to develop functional maternity wear with multi-purposes such as breast-feeding, wearability after delivery and shielding from microwave.

The aim of the present study was to evaluate the degree of metal contamination of the Turag River water and its suitability for irrigation. Twenty water samples were analyzed for physicochemical parameters and metals viz., calcium, magnesium, potassium (K), sodium, copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), lead (Pb), cadmium (Cd), chromium (Cr), and nickel (Ni). All water samples were slightly alkaline to alkaline. Regarding electrical conductivity (EC), all samples were suitable for crop in soils with moderate permeability and leaching. Water samples were medium salinity and low alkalinity hazard classes. In terms of total dissolved solids (TDS), all samples were classified as freshwater. As per sodium adsorption ratio (SAR) and soluble sodium percentage (SSP), all samples were classified as excellent. No residual sodium carbonate (RSC) was detected in any of the samples, indicating suitability for irrigation; and all samples were considered very hard. Cr and Mn contents in all samples were above FAO guideline values and, therefore, these metals were considered toxic. Zn, Cu, Pb, Cd, and Ni concentrations were below acceptable limit for irrigation and do not pose a threat to soil environment. Significant relationships were found between EC and TDS, SAR and SSP, SAR and RSC, and SSP and RSC. The combinations of ions such as K-Zn, K-Fe, K-Cu, K-Mn, K-Pb, Zn-Fe, Zn-Cu, Zn-Mn, Fe-Mn, Cu-Mn, Cu-Pb and Mn-Pb exhibited significant correlation. This study revealed that Turag River water samples are contaminated with Cr and Mn. This fact should not be ignored because water contamination by metals may pose a threat to human health through food chain.

We interviewed and surveyed parents of 3 to 6-year-old boys in order to determine designs for indoor apparel that appealed to toddlers. In addition, on the basis of the behavioral characteristics of such boys, improvements in the development of indoor apparels were suggested. Parents preferred indoor apparels because it could be worn as underwear when the kid is outdoors and as outerwear when indoors. These apparels were popular with toddlers. Therefore, indoor apparel that gives the impression of outerwear while performing the function of underwear was designed. Underwear fabric was used, but outerwear apparel design was partially adopted. In order to improve the activity, fabric that could be stretched in any direction was used for the sleeves and pant legs, while organic fabric with soft texture was used for the trunk part of the apparel. Dark-colored material was used for the chest and elbow parts of the clothes in order to prevent contamination in these parts. In particular, a bib was used to prevent contamination in the chest part. Given that toddlers engage in many activities, the fabric needed to be durable, so this led to thick materials being used for the knee part. As certain parents complained about the short length for tops, we increased the length of the tops by 5cm. In the survey items that investigated overall wearability, ease, and suitability for toddlers' activities, the test apparel obtained a higher score than existing apparel did. This indicates that the overall suitability of the newly designed apparel was improved.
