  • Epoxy resin has wide application in various industrial fields because of their good mechanical strength, superiority adhesion and low shrinkage etc. And the typical curing method for epoxy resins is thermal and press compaction. However, a curing method was used electron beam process in this study. Epoxy acrylate was fabricated from mixture of epoxy, acrylic acid, tetraphenylporphyrin (TPP) and hydroquinone monomethyl ether (MEHQ) with mole ratios. Then electron beam irradiation effect on the curing of the epoxy acrylate resin was investigated various absorption dose in nitrogen atmospheres at room temperature. The dynamic mechanical and thermal properties of the irradiated epoxy acrylate resins were characterized using dynamic mechanical analysis (DMA) and thermogravimetric analyzer (TGA). And the tensile and flexural strength were measured by an universal tensile machine (UTM).

  • Wood has different properties depending on the species or growth area. Therefore, in order to use wood efficiently, it is necessary to have a proper understanding of the characteristics of wood depending on the species and the appropriate use for them. In particular, in order to effectively use more than 1,000 species of woody plants in South Korea as wood, it is necessary to evaluate the characteristics of various Korean domestic woods and make a database of them. In this study, the anatomical properties (length and width of tracheid, cell wall thickness), physical properties (specific gravity and shrinkage), mechanical properties (bending strength, compressive strength, tensile strength, shear strength, hardness), and chemical composition (ash, extract, lignin, total sugar content) of Korean red pine which was grown in Pyeongchang-gun, Gangwon-do, South Korea were evaluated.

  • The purpose of this study aims to the improvement prospect of green insurance industry in Korea. Green insurance includes all classes of general insurance business including unoccupied property insurance and empty building insurance, business insurance, personal insurance, etc. Green policies often cover expensive systems that are not covered under most property policies. The same is true for some underground property, which is also exempted from many property policies. At least insurers already offer products designed to fund rebuilding damaged properties to meet certain environmental and building standards. While the products are in their infancy, insurers and brokers say the huge interest in environmental issues will increase demand. Green buildings that improve energy efficiency and air quality and reduce waste are designed to reduce their effects on the environment and the health of building occupants. Buildings account for 39% of U.S. carbon dioxide emissions, according to the Department of Energy. Insurers say that, as sustainable buildings become more common, green insurance will become more popular and some of its features might become a standard part of property policies.

  • Objective: The objective of this paper is to review the interests and limitations of ergonomics regarding intellectual property. Background: There have been less interests in intellectual property among the ergonomics professionals. However, the importance of intellectual property is increasing as competitions in industry are getting fierce. Method: Literatures on the relations of intellectual property with ergonomics were examined, and the international patent classification system was studied. Results: No profound studies were found in the area of the relations of intellectual property with ergonomics. Ergonomics was not considered in patent classification. Conclusion: It is important to induce more interests regarding intellectual property to the community of ergonomics. Further studies are expected on the relations of intellectual property with ergonomics. Application: The results from this paper would be of help to inducing ergonomists to more interests in intellectual property.

  • The surface property of the materials used in tissue engineering application has been essential to regulate cellular behaviors by directing their adhesion on the materials. To modulate surface property of the synthetic biodegradable materials, a variety of surface modification techniques have used to introduced surface functional groups or bioactive molecules, recently polydopamine coating method have been introduce as a facile modification method which can be coated on various materials such as polymers, metals, and ceramics regardless of their surface property. However, there are no reports about the degree of polydopamine coating on the materials with different hydrophilicity. In the present study, we prepared acrylic acid grafted nanofibrous meshes using electron-beam irradiation, and then coated meshes with polydopamine. Polydopamine successfully coated on the all meshes, both properties of acrylic acid and polydopamine were detected on the meshes. In addition, the degree of polydopamine deposition on the materials has been altered according to surface hydrophilicity, which was approximately 8-times greater than those on the non-modified materials. In conclusion, dual effect from the acrylic acid grafting and polydopamine may give a chance as a alternative tool in tissue engineering application.

  • Many countries have been developing BIM-based building code checking system and studies in the utilization of Industry Foundation Classes (IFC) in building code checking. IFC is the open standard of BIM format. Currently, there is a disadvantage that could not include all of the attribute for the regulations of each country and there is the problem with the interoperability of the different defined IFC approach between BIM software. This study focus on developing, derived object and property by comparing through domestic regulation and IFC2x3 specification provided by the buildingSMART and classified review type depending on the interoperability of derived information. According to classified review type, the IFC data structure was established and property mapping contents were developed by including BIM software compatible information and creating a type of review plan. When the developed property mapping contents are applied into BIM-based building code checking system, checking of the BIM data generated from various fields is made effective and thus improving the interoperability of information.

  • In case of sense case manufactured by method of outage capacity, sensitivity is declined by outside effect and method of the photo electricity has a problem in transmission. therefore, packing case of composite sense should be developed to improve such a problem about influence of outside environment and its property evaluation has been performed. Mechanical property and result of analysis & test evaluation of Mat'l on aluminum die-casting(ADC 12type) Mat'l developed are as following. Tensile test piece, No. 4 of KS B 0801, has been applied to mechanical property test of Mat'l and It has been tested by method of metal mat'l tensile test(KS B 0802 : 2003). It can be found that physical property to KS(Korea Standard) is excellent. and homogeneous mechanical property appears. Test of Mat'l analysis has been performed by using OE Spectrometer, according to ASTM E 1251 : 1994 regulation. Consequently, good and homogeneous component contents classified by element to standard, except for Fe, have been obtained with coordination of Fe content as below 1.3% from composition standard of Aluminum Die-casting.

  • Since industry and technology are being developed through interactions, intellectual property (IP), which are used as a substitute for technology, are found to have a close relationship with industry. The current status of IP and the business revenue differences of enterprises of south Korea are analyzed in the disaster-safety industry. Only 2.66% out of 49,538 firms have IP, indicating that most companies do not have IP. The difference in sales due to the ownership of IP is not statistically significant in middle-standing enterprises, but that of medium and small-sized enterprises (SMEs) is statistically significant. It is also found that 17 Divisions, which have IP, out of 21 Divisions in the Disaster-Safety Industry Special Classification of Korea have higher business revenue, and 10 Divisions of those 17 Divisions indicate statistical significance. In conclusion, the ownership of IP is one of the factors affecting the difference in business revenue for SMEs in Korea, implying that it is important to focus on creating and securing IP.
