It has been recognized that international food standards should be considered for a long time. The Codex Alimentarius programme initiated in the early 1960s has received valuable background documentation from the ICMSF (International Commission on Microbiological Specification for Foods) and also from ISO(the International Organization for Standardization). There has been a considerable move towards international harmonization of standards and methods of analysis. Many foreign countries recommend the guidelines for food microbiological standards quantitatively. To complement microbiological limits and tolerance levels for permissible number of defective samples, allowances should be made for sampling and other variations in laboratory methods. It may be necessary for guidelines of domestic food microbiological standards to be established so that the domestic food standards can be harmonized with foreign food standards. Food safety related microbiological guidelines of ICMSF, EU (European Union), UK (United Kingdom), China (Hong Kong) and Japan were reviewed and shown in examples.

The new article, related to temporary copy on exploitation of copyrighted works, has been introduced in the copyright law as partly revised on December 2, 2011. While number of researches on in-network caching including Content-Centric Networking are conducted quite actively in recent years, the need for legal and institutional considerations has arisen since temporal storage (i.e. temporal copy) may be made not only at user devices but also in routers such as network equipments. This paper examines issues on temporary copy of copyrighted works mainly focusing on the articles and the related articles of the recently revised copyright law as well as the Free Trade Agreement between the Republic of Korea and the United States of America and further studies necessary institutions required to actualize in-network caching.

In this paper, we implement an identification system using the vein image of the hand. The vein pattern is obtained in the grey-scale 2D image through the infrared-red imaging from back of the hand. Since the frame has lack of clearance, we use some enhancing methods such as the complement, addition, and multiplication to the image to increase the contrast. After Wiener filtering for smoothness of the vein pattern, we transform the image into the binary image with mean function. The binarized image is session thinned and the cross-points in the vein tree are obtained by calculating the number of pixels connected because the image is shaped as a tree. We choose the point and find the nearest to the center if it has majority, where we find the two end points of the selected line. We can get the angle between the two lines joined at the cross-point and store its coordinates, angle, and label the values. The values are used as the feature vector of the vein pattern. This procedure is similar to the human cognition sequences. It is shown that the proposed method is simple for the vein recognition.

In this paper, an improved detection method is Proposed by supplementing multi-path gain for a MMSE detecter. This method is Proposed to complement the shortcomings of the conventional detection method which is used for multiuser detection in STBC CDMA system. We analyzed the improved method in bit error Probability viewpoint and compared the result with that of the conventional method In this result, we showed that the improved method obtains better performance of bit error probability than the conventional method when parameters such as delay, number of user and SNR are increased.

The primary goal of this paper is to propose methods of enriching two heterogeneous ontologies: Sejong Semantic Classes (SJSC) and KorLexNoun 1.5 (KLN). In order to achieve this goal, this study introduces the pros and cons of two ontologies, and analyzes the error patterns found during the fine-grained manual mapping processes between them. Error patterns can be classified into four types: (1) structural defectives involved in node branching, (2) errors in assigning the semantic classes, (3) deficiency in providing linguistic information, and (4) lack of the lexical units representing specific concepts. According to these error patterns, we propose different solutions in order to correct the node branching defectives and the semantic class assignment, to complement the deficiency of linguistic information, and to increase the number of lexical units suitably allotted to their corresponding concepts. Using the results of this study, we can obtain more enriched ontologies by correcting the defects and errors in each ontology, which will lead to the enhancement of practicality for syntactic and semantic analysis.

A karyotype analysis of the chromosome of Neodiplostomum seoulense, one of causative agents of human intestinal trematodiasis, was done from the gonad tissue by the squashing method. The chromosome number was n=10 and 2n=20. Chromosome length was $1.30-4.0{\;}\mu\textrm{m}$. Chromosome pairs in the complement consisted of two pairs of metacentric, five pairs of submetacentri$cs_telocentric and three pairs of telocentric chromosomes. These data were comparable with those of other intestinal trematodes.es.

There are many uncertainties in structural failures or structures, so probabilistic failure cause assessment should be performed in order to consider the uncertainties. However, in many cases of forensic engineering, the failure cause assessments are performed by deterministic approach though number of uncertainties are existed in the failures or structures. Thus, deterministic approach may have possibility for leading to unreasonable and unrealistic failure cause assessment due to ignorance of the uncertainties. Therefore, probabilistic approach is needed to complement the shortcoming of deterministic approach and to perform the more reasonable and realistic failure cause assessment. In this study, reliability-based failure cause assessment (reliability based forensic engineering) is performed, which can incorporate uncertainties in failures and structures. For more practical application, the modified ETA technique is proposed, which automatically generates the defected structural model, performs structural analysis and reliability analysis, and calculates the failure probabilities of the failure events and the occurrence probabilities of the failure scenarios. Also, for more precise reliability analysis, uncertainties are estimated more reasonably by using bayesian approach based on the experimental laboratory testing data in forensic report.

Efficient routing algorithm is required to transmit data from source to destination by multi-hop transmission in wireless sensor networks. In the multi-hop transmission, multipath routing can be one of the solutions to cope with the traffic congestion and unstable link condition. In this paper, we propose partial multipath routing which does not establish a secondary full routing path but a partial multipath to complement some poor links, and it can enable stable data transmission and reduce the number of nodes in routing path and the required total power compared with conventional multipath routing.

Cytogenetic analysis of Anemarrhena ashodeloides BUNGE, which is one of medicinal plants belonging to Haemodoraceae was carried out using Feulgen staining. The somatic metaphase chromosome number was identified to 2n=22 (x=11) and the size of chromosomes ranges from $1.27-3.80\;{\mu}m$. Three pairs of chromosomes were relatively long in total length and the others were short. The karyotype was bimodal in chromosome length and arm ratios. The chromosome complement comprise eight pairs of metacentric (chromosome 2, 3, 6, 7, 8, 9, 10, and 11), two pairs of submetacentric (chromosome 4 and 5), and one pair of subtelocentric (chromosome 1).

In this paper, an improved detection method is proposed by supplementing various types of Proportional gam for a MMSE detecter. This method is proposed io complement the shortcomings of the conventional detection method which is used for multiuser detection in STBC(Space-Time Block Code) CDMA system. We analyzed the improved method in bit error probability viewpoint and compared the result with that of the conventional method. In this result, we showed that the Improved method obtains better performance of bit error probability than the conventional method when parameters such as delay, number of user and SNR are increased.
