In December 2014, Livestock and Livestock Products Traceability Act was established, allowing consumers to receive livestock traceability information. While the Livestock Traceability System provides consumers with transparent and fair information about their food, it has brought increased workload and penalty burdens to stakeholders in the livestock industry. In this paper, we propose an IoT system for inventory management based on traceability numbers to enable sellers to conveniently provide livestock traceability information to consumers. We analyzed the protocol for managing data from electronic scales and conducted functional testing and verification on mobile devices. Furthermore, we implemented the design and system functionality, taking into account UI/UX on Android OS-based devices to synchronize and interconnect traceability and product information with electronic scales. We anticipate that the proposed approach will minimize user inconvenience and raise production efficiency in the existing market.

The purpose of this study was to explore the characteristics of and solution to thermogenic reactions to Korean ginseng through bibliographic research. A review of bibliography on the thermogenic reaction induced by ginseng indicated that people who lack fluids, have fever in lungs, a stuffy chest, coughing up sputum, a strong pulse, and constipation due to fever in the stomach may exhibit such a reaction. In the herbal medicine book of the Qing Dynasty, Bon-Cho-Jeong-Ui (本草正義) recorded that wild simulated ginseng is slightly cold and replenishes the body's liquid reserves. The book also describes the field cultivated ginseng is slightly warm and enhancing stamina. Bon-Kyung-Bong-Won (本經逢源), Bon-Cho-Pyon-Dok (本草便讀), and Bon-Cho-Jeong-Ui were published authors in the Qing Dynasty, and they explained that ginseng fine root is bitter, supplements bodily fluids, and can be easily ingested because it is cold. Wol-Ji-In-Sam-Jeon (月池人蔘傳) and Bon-Cho-Bi-Yo (本草備要) described fresh ginseng assweet, bitter, and slightly cold in the Ming and Qing Dynasties, respectively. On the basis of this bibliographic description, the thermogenic reaction induced by Korean ginseng can be overcome by using ginseng fine root, fresh ginseng, or wild simulated ginseng. These ginseng radices are slightly cool, replenish human bodily fluids, and show the physiological effects of easy ingestion properties.

Bolted opening structures is widely applied for class 1 machinery of nuclear plant with strict design requirement. As the shape of the bolted opening structure is non-axisymmetric due to the existence of stud bolts although it is almost axi-symmetric, 3D analysis is required to satisfy such kind of design requirements. Because as much as possible trial computations are need to get an optimal design condition in the limited period of basic design, an easy and fast analysis tool is useful in the design stage. In the paper, a transformation technique of non-axisymmetric problem into quasi-axisymmetric has been proposed based on the general purpose commercial code ANSYS. Both the pre-processor which incorporates the technique and prepares data and post-processor which prepares arranged results from the huge output of commercial code have been developed to help the design engineers.

The aim of the study was to investigate the ability of sperm derived from the epididymis in regard to sperm motility, sperm penetration to oocyte and subsequent development of the embryo. Frozen-thawed sperm from epididymis showed similar percentage of motile sperm (VSL ${\geq}25{\mu}m/sec$) as compared to that of commercial sperm (control). Sperm penetration of frozen-thawed epididymal and commercial sperm was not significantly different. Moreover, cleavage and blastocyst rates were similar in both epididymal and control. Sperm derived from the epididymis also showed fertilizability and subsequent embryonic development.

The bipolar plate is a major component of the PEM fuel cell stack, which takes a large portion of stack cost. In this study, as alternative materials for bipolar plate of PEM fuel cells, graphite composites were fabricated by compression molding. Graphite particles mixed with epoxy resin were used as the main substance to provide electric conductivity. To achieve desired electric properties, specimens made with different mixing ratio, processing pressure and temperature were tested. To increase mechanical strength, one or two layer of woven carbon fabric were added to the original graphite and resin composite. Thus, the composite material is consisted of the three phases: graphite particles, epoxy resin, and carbon fabric. By increasing mixing ratio, fabricated pressure and process temperature, electric conductivity was improved. The results of tensile test showed that the tensile strength of two-phase graphite composite was about 5MPa, and that of three-phase composite was increased to 54MPa.
