  • From a practical perspective, sustainable development requires the optimization of current natural resources and the minimization of derived wastes. A major concern with respect to sustainable infrastructure development is the continued depletion of easily-available natural resources and environmental matters are more serious, the concerned about waste materials which are inevitably produced in the manufacturing of the product is getting worse. These wastes must be handled and properly disposed, and many times, although this waste may be environmentally inert, it has been discarded in landfills. But current disposal methods of these by-products create not only a loss of profit for the power industry, but also environmental concerns the breed negative public opinion. therefore, this study evaluates the ECO artificial aggregate and bricks were designed and tested for the end use of fly ash.

  • The cerebral neurosecretory cells (NSC) constitute four paired groups, medial (MNC), lateral (LNC-I, LNC-II) and posterior (PNC) in the brain of larvae of tasar silkworm Antheraea mylitta (D) Eco-race Bhandara. The MNC is the largest groups of peptidergic neurosecretory cells and are located in the pars intercerebralis region. The transmission electron microscopic (TEM), ultrastructure of the NSC confirmed the presence of mitochondria, endoplasmic reticulum, Golgi bodies, lysosomes and neurosecretory granules. The median neurosecretory cells shows secretory activity and release of secretory products, the neurosecretory granules (NSG) in the axons of NSC as well as the blood sinus.

  • Non-timber forest products are important component of subsistence and livelihood of tribal communities living in and near forests. This is of particular significance in the state of Arunachal Pradesh having more than 80% of geographical area under forest cover and predominantly inhabited by tribal people. Purpose of this study was to document the status and utilization pattern and to assess the economic value of NTFPs of the state. Present study was carried out in eight districts of Arunachal Pradesh viz., Changlang, East Kameng, Lower Subansiri, Tawang, Tirap, Upper Siang, West Kameng and West Siang covering 34 villages and 350 households. Altogether, 135 plant based and 36 animal based non-timber forest products were recorded. Among plant based NTFPs, 54 species were collected for leaves, 30 for stem and 22 for fruits. Most of the animal based NTFPs (93%) were collected/hunted for food. Average 20~40 kg of NTFPs was collected annually per household. Maximum plant based NTFP collection was recorded from West Siang followed by West Kameng and Tawang. Similarly, highest collection of animal based NTFPs was recorded from West Siang followed by Tirap and Lower Subansiri. NTFP contributed more than 50% of annual income of the people of East Kameng, Tirap, Lower Subansiri and Upper Siang districts. An illiterate and unemployed person with minimum agricultural land was more dependent on forests for his livelihood than a literate jobholder. The study concludes that a large section of people of Arunachal Pradesh are dependent on NTFPs for their livelihood however due to its unscientific harvesting, the availability of NTFPs is receding with time. There is an urgent need to promote cultivation and scientific harvesting of NTFPs in order to conserve the plant and animal diversity of this global biodiversity hotspot and for ensuring livelihood security of the people living in this area.

  • The purpose of this study is to develop up-cycling fashion design methods centered on discarded denim material for the study of original up-cycling design methods. Up-cycling fashion design work was developed using digital clothing technology. This is a recent hot topic among sustainable fashion design methods. Up-cycling fashion design expression methods (categorized as dismantlement, collages, dépaysement, grafting, weaving, and tearing) were centered on design methods. These methods create various three-dimensional modeling effects in planar forms, whereby five pieces can be applied to the fabric and digitally produced. The results are as follows: First, the use of discarded denim fabric for the development of up-cycling fashion design pieces enabled the recycling of existing resources, provided solutions to environmental pollution problems, and provided expansion opportunities for design processes for sustainable fashion products that expand the design value of denim products and their utility. Second, new eco-friendly fashion designs that attempt to achieve diversity in modern fashion trends could be presented through formative contemporary fashion produced by up-cycling work products. Third, up-cycling fashion design work is expected to provide opportunities for eco-friendly fashion design methods. This will expand the value of sustainable fashion design by recycling simple waste materials through the use of three-dimensional digital clothing technology and further through the presentation of expanded life cycles that extend product planning, production, and life cycles.

  • Generation MZ, a generic term for millennials and members of Generation Z, is an innovation-leading consumer group in the current market. This study aimed to examine the impact of the ethical consumption tendencies of millennials and Generation Z on the purchase intention of social enterprise fashion products. Data were collected from Generation MZ (15-40 years old) by quota sampling based on the demographic variables of gender, age, and region, respectively. Eight hundred responses were analyzed by descriptive statistics, factor analysis, t-test, and regressions using SPSS software. Three value factors (egoistic, altruistic, and biospheric) and three ethical consumption tendency factors (resource saving tendency, eco-friendly tendency, and consciousness of corporate responsibility) were determined by factor analyses. The results confirmed that women, who showed a higher ethical consumption tendency in all three factors, were more altruistic and biospheric than men. Furthermore, women portrayed a more favorable attitude and purchase intention towards fashion products of social enterprises. The results demonstrated that members of Generation Z were more altruistic and biospheric than millennials. Additionally, the attitude, purchase intention, and willingness to pay premium prices were higher in Generation Z members. It was confirmed that higher biospheric values correlated with greater values for the three ethical consumption tendency factors. The altruistic value affected both the resource saving tendency and eco-friendly trend, while the egoistic value had an effect on the resource saving tendency. Both attitude and purchase intention were positively influenced by all three of the ethical consumption tendency factors, and affected the willingness to pay premium prices. This was subsequently influenced by the resource saving tendency and consciousness of corporate responsibility. The results of this study contribute to understanding Generation MZ as a consumer group, and the establishment of marketing strategies for fashion companies.

  • Cellulase is an eco-friendly biocatalyst, and its demand is growing in many industrial applications such as food, textile, paper, and bioenergy. Strains with a high cellulase activities are the starting point for the economic production of cellulase. In a previous study, Acanthophysium sp. KMF001 with high cellulase production ability was selected among 54 wood-rotting fungi. In this study, we evaluated the cellulase productivity of Acanthophysium sp. KMF001 quantitatively and analyzed its taxonomic location using a genetic method. Acanthophysium sp. KMF001 showed high cellulase productivity similar to that of Acanthophysium bisporum and was much better than A. bisporum in specific enzyme activity. The 28S rRNA sequence of Acanthophysium sp. KMF001 was similar to that of Acanthophysium lividocaeruleum MB1825, with 98.40% homology. Phylogenetic analysis suggested that Acanthophysium sp. KMF001 is a new strain. In this study, we propose a new strain with high cellulase productivity.
