  • This study introduces a new delivery method for designs as observed in the artwork trends of Damien Hirst and reflected in the unique expression methods of Modern fashion Collections. The study analyzed numerous resources (literature, dissertations, magazines, and the internet) about Damien Hirst and the examination of a modern fashion timeline is limited to after the 2000s. The 'grotesque trend' that appears in Damien Hirst's works can be classified into five categories (fragmented animal, mismatch, excessiveness and exaggeration, comedy and awfulness, and abnormality). Based on this, the study found that heterogeneous, abject abhorrence, double sided of the play, exaggerated atypia and devilishness in Modern fashion. This study suggests a positive direction for the 'grotesque technique' that could be recognized as one of the delivery methods for a unique fashion design based on the attachment of an aesthetic value that supersedes bizarreness and strangeness to expand various methods of expression.

  • Home appliances go through a couple of packaging stages from the plant to consumers. The primary packaging, inner packaging for each part, happens for protection after products leave the plant. The secondary packaging happens in the unit of product, ensuring cushioning packaging to protect products from movement. The final tertiary packaging is for transportation and delivery. Each stage of product packaging, however, costs a lot of money because of disposable packaging materials used in each stage including vinyl, tapes, Styrofoam, and corrugated cardboards. Discarded packaging materials also cause environmental problems. In an effort to come up with a measure to solve those problems, this study proposed a plan to minimize logistics costs with semi-permanent packaging materials to replace disposable ones including Styrofoam, vinyl, and corrugated cardboards in the stages of inner packaging, cushioning packaging, product unit-based packaging, and transportation. The study also developed a model to cut down logistics costs by reducing various packaging stages including the primary, secondary, and tertiary stage only to the secondary one through module-type products instead of the transportation- and delivery-type ones, as well as demonstrated the excellence of the study through numerical analysis.

  • Basically Mobile Ad Hoc Network (MANET) is an autonomous system with the collection of mobile nodes, these nodes are connected to each other by using wireless networks. A mobile ad hoc network poses this quality which makes topology in dynamic manner. As this type of network is Ad Hoc in nature hence it doesn't have fixed infrastructure. If a node wishes to transfer data from source node to a sink node in the network, the data must be passed through intermediate nodes to reach the destination node, hence in this process data packet loss occurs in various MANET protocols. This research study gives a comparison of various Mobile Ad Hoc Network routing protocols like proactive (DSDV) and reactive (AODV, DSR) by using random topology with more intermediate nodes using CBR traffic. Our simulation used 50, 100, and 150 nodes variations to examine the performance of the MANET routing protocols. We compared the performance of DSDV, AODV and DSR, MANET routing protocols with the result of existing protocol using NS-2 environment, on the basis of different performance parameters like Packet Delivery Ratio, average throughput and average end to end delay. Finally we found that our results are better in terms of throughput and packet delivery ratio along with low data loss.

  • Nowadays many academic libraries have considered and some have implemented the just-in-time(access) approach to collection development especially of scholarly journals. The adaption of the scholarly electronic journal based on access paradigm has brought a number of advantages and disadvantages to academic libraries. Electronic journals have promised rapid delivery of the latest research to the desktop through the ubiquitous platform of the Internet. But the promise of the e-journal is not yet a reality, and there are many misconceptions about what is actually available today. The objective of this paper is to analyse the probabilities of digital achilles tendon of scholarly journals resulting from a decline of purchase power, absence of selection(evaluation) criteria, superfluities and abuses of impact factor, access paradigm and halo effects, mismatching of demand-supply, md insufficiency in subject gateway functions.

  • The purposes of this study was to identify fashion shoppers' perceived risk and satisfaction while shopping at overseas online shopping malls based on their internet shopping values. A self-administered questionnaire was used for data collection and an internet survey was conducted from April 12~15, 2015. Most consumers purchased one or two fashion items at overseas online malls directly, motivated by low prices, and spent 200,000~400,000 won during the last one year. The factors of consumers' internet shopping values were information, hedonics, and practicality. Factors of perceived risk were delivery and refund, price and approval, and product and shopping mall. Consumers were divided into three categories: heavy pursuit shoppers, intermediate shoppers, and uninformed shoppers based on their internet shopping values. Heavy pursuit shoppers were primarily female; they spent more, felt a deeper patronage with overseas online shopping malls and their perceived risk regarding delivery and refund was higher than the other shoppers. The group of uninformed shoppers were primarily male. They spent less, had low patronage with overseas online shopping malls, and their perceived risk regarding delivery and refund was lower than other shoppers. Overall satisfaction was positively affected by information provided while shoppers were surfing the overseas online shopping malls and practicality. Satisfaction was negatively affected by perceived risk regarding price and approval and difficulty in finding specific products while shopping at overseas online shopping malls.
