Geographical indications are place names (in some countries also words associated with a place) used to identify the origin and quality, reputation or other characteristics of products. Protection required under the TRIPS Agreement is defined in two articles. The purpose of this study is to select the representative geographical indication item of Korea, discuss of the new intellectual property rights, and promote the trade of that product. It is also discussed of a geographical indication registration system and the recognition with international point of view. The international geographical indication protection is strengthening in recent. There are many multilateral and bilateral discussions and talks for geographical indication system. In order to protect excellent Korean products locally and internationally, the 'Quality Management of Agricultural Products Act' has been introduced form July 1, 1999. The geographical indication registration of Korea currently is 31 cases. The geographical indication is limited the regional promotion in Korea. Therefore, it is studied the registered items on the list and analyzed the result of the registration. Consequently, this paper suggests that more effective ways have to be prepared for the systematic management of geographical indications, campaigns for the recognition as a property.

FRMLs(Fiber Reinforced Metal Laminates) is a new type of hybrid materials. FRMLs consists of high strength metal and fiber which are laminated using a structural adhesive bond(epoxy resin). The effect of resin mixture ratios on the fatigue crack propagation behavior and mechanical property of Aramid fiber reinforced aluminum composites was investigated. The epoxy, diglycidylether of bisphenol A(DGEBA) was cured with methylene dianiline(MDA) with or without accelerator(K-54). Eight kinds of resin mixture ratio were tested for the experiment ; five kinds of FRMLs(1))epoxy & curing agent) and three kinds of FRMLs(2)(epoxy & curing agent & accelerator). FRMLs(2) have a more effective characteristics on the fatigue crack propagation behavior and mechanical property than FRMLs(1)

The main objective of this study was to investigate the packing state and optical properties of coated paper prepared with different coating colors by varying the blending ratio of such pigment as clay, $CaCO_3$, and plastic pigment. To evaluate the effect of packing state of pigment on the properties of coated paper, the coating thickness, which was theoretically calculated by specific gravity, and packing volume of pigment were used. It was found that there exists close relationship between the coating thickness and surface property of coated paper. For instance, the macro roughness(smoothness) of coated paper is closely related to bulkiness. Plastic pigments used in this research has a high finishing efficiency on the light weight coatings. Especially, hollow sphere pigment was very effective for improving the property of coated paper produced in this test. And when HSP was blended with $CaCO_3$the surface property such as smoothness and gloss improved significantly.

This study focuses on the legal concept of virtual money, focusing on the case of how we can change the framework of fixed thinking about our trade concept and money with the fourth industrial revolution. The legal character of the virtual money, which played a role as a means of trading in crime, could be discussed, and the court could put it in the category of " property " as a subject of confiscation. Many people are expressing empathy for the fact that there will be many traits in the future world that are difficult to predict. At this side, when the legal validity of the advantage is not recognized as the legal money yet to be recognized as the legal currency, it begins to be discussed as a necessary means of trading between individuals, businesses and individuals. Defining a legal character can be very significant in determining policy direction related to future operations of virtual money. But to date, it is very difficult to establish the legal character of virtual money through existing legislation. Therefore, as we looked at in this case, we examined whether the property was subject to the seizure of the profits from the crime. Attention was also given to the possibility of such abuse of virtual money and whether effective legal interpretation was possible for the categories of assets subject to seizure.

Optical property improvements for ONP (old newspaper) and OMG (old magazine) were attempted by application of in-situ $CaCO_3$ formation process on recycled fiber surfaces. Washing treatment of ONP and OMG resulted in 35~40% yield loss for around 6% brightness improvement. Washing plus bleaching process with $H_2O_2$ and FAS (formamidine sulfinic acid) improved brightness and ERIC values a little more with the same amount of yield loss as washing treatment. In-situ $CaCO_3$ formation method improved those optical properties much better than the washing plus bleaching method without loss of yield, and better than the case of adding high brightness PCC up to the same ash level. It can be said that the in-situ $CaCO_3$ formation method may be used as an effective alternative for upgrading optical properties of recycled fibers.

This study was conducted to investigate the applicability of gamma irradiation for improving the quality of paprika and Japanese apricot extract-treated nitrite free pork jerky. Pork jerky was gamma-irradiated at 0, 3, 5, 7 and 10 kGy and physiochemical properties such as proximate composition, 2-thiobarbituric acid (TBARS) values, color stability, texture, and sensory property were then evaluated. The results showed that the treatment of paprika and Japanese apricot extract to the pork jerky increased Hunter color value and texture property and at the same time decreased TBARS values. When gamma irradiated, natural pigment extract-treated pork jerky did not produce any change in its proximate composition (moisture, crude protein, crude lipid contents), and TBARS values. However, the redness (a-value) of pork jerky increased as the irradiation dose increased, whereas shear force of pork jerky was decreased. Sensory result showed that gamma irradiation induced to decrease the sensory scores. Therefore, these results suggest that gamma irradiation and the addition of paprika and Japanese apricot extracts could be an effective mean to improve color and texture of restructured pork jerky without use of nitrite.

Software reliability has the greatest impact on computer system reliability and software quality. For this software reliability analysis, In this study, we compare and analyze the trends of the properties affecting the reliability according to the shape parameters of Erlang distribution based on the finite fault NHPP. Software failure time data were used to analyze software failure phenomena, the maximum likelihood estimation method was used for parameter estimation. As a result, it can be seen that the intensity function is effective because it shows a tendency to decrease with time when the shape parameters a = 1 and a = 3. However, the pattern of the mean value function showed an underestimation pattern for the true values when the shape parameters a = 1 and a = 2, but it was found to be more efficient when a = 3 because the error width from the true value was small. Also, in the reliability evaluation of the future mission time, the stable and high trend was shown when the shape parameters a = 1 and a = 3, but on the contrary, when a = 2, the reliability decreased with the failure time. Through this study, the property of finite fault NHPP Erlang model according to the change of shape parameter without existing research case was newly analyzed, and new research information that software developers can use as basic guideline was presented.

Analysis for structures composed of materials containing regularly spaced in-homogeneities is usually executed by using averaged material properties. In order to evaluate the effective properties, a unit cell is defined and loaded somehow, and its response is investigated. The imposed loading, however, should accord to the status of unit cells immersed in the macroscopic structure to secure the accuracy of the properties. In this study, mathematical description for the periodicity of the displacement field is derived and its direct implementation into FE models of unit cell is attempted. Conventional finite element code needs no modification, and only the boundary of unit cell should be constrained in a way that the periodicity is preserved. The proposed method is applicable to skew arrayed in-homogeneity problems. Homogenized in-plane elastic properties are evaluated for a few representative cases and the accuracy is examined.

Permeability was not represented as a simple function of the difference between confining pressure($P_c$) and pore pressure($P_p$). The effective pressure($P_e$) for measurements of the permeability is shown to be $P_c-{\alpha}P_p$, where $\alpha$ is a coefficient of effective pressure. Local values of $\alpha$ were determined at intervals along the pressure path which range 25MPa to 55MPa. The values of $\alpha$ ranged 0.65 to 1.09 for Pocheon granite and 1.20 to 1.43 for Wonju granite. Also, the value of $\alpha$ calculated by the cross-plotting method was 0.90 for Pocheon granite, 1.59 for Wonju granite and 4.35 for jointed Pocheon granite. $\alpha$ was found to be stress-history dependent.
