This study was carried out to establish the consumer-centric food labeling system by investigating usage state, importance evaluation, problems and satisfaction, etc. on the current food labeling system by consumer. For usage state of checking the food label, 50.2% of respondents were replied ‘mostly check the label’, and they were indicated a significant difference on ‘education level(p<.05)’, and in case of married respondents, most were relied 'absolutely check the label', For the reason to check the food label, 61.8% of respondents were replied 'to determine whether it is stable or not', and they were indicated a significant difference on age(p<.01), marital status(p<.01), and job(p<.01). For the item considered as important things on the label of the whole food, 49.8% of respondents were replied that 'expiration and manufacture date is important', and they were indicated a significant difference(p<.001) on age, marital status, job. For item considered as important things on the label of each food, it was indicated that they considered food company as important thing in case of snack, soft drink, edible oils, and noodles, and food company in case of ice cream, and expiration and manufacture date in case of milk product and meat product. For the problems on the current food labeling system, the clauses 'Poor marking on food additives and materials contents' and 'untrue marking of nutrition contents' were indicated a significant difference on age(p<0.05, p<0.001), and the clause 'untrue marking of nutrition contents' were indicated a significant difference on marital status(p<.01) and job(p<.01).

The vulnerability issue on IEEE 802.1x wireless LAN has been permits the malicious attack such as Auth/Deauth flooding more serious rather than we expected. Attacker can generate huge volume of malicious traffic as the same methods on existing wired network. The objective of wireless IP Traceback is to determine the real attack sources, as well as the full path taken by the wireless attack packets. Existing IP Traceback methods can be categorized as proactive or reactive tracing. But, these existing schemes did not provide enhanced performance against DoS attack on wireless traffic. In this paper, we propose a 'TTL based advanced Packet Marking' mechanism for wireless IP Packet Traceback with wireless Classification function. Proposed mechanism can detect and control DoS traffic on AP and can generate marked packet for reconstructing on the real path from the non-spoofed wireless attack source, by which we can construct secure wireless network based on AP with enhance traceback performance.

The standardized algorithm of natural number multiplication simplify the procedure of arithmetic. In the case of multiplication algorithm with regrouping, we write small the carrying number on the multiplicand. But, teachers and students have to make their own way about the case of two digits multipliers, because Korean elementary mathematics textbooks just deal with the case of the one digit multipliers. In this study, we investigated Korean current elementary mathematics textbooks related to multiplication algorithm with regrouping, and analyzed the result of research on the real condition about marking the carrying number. Besides, we reviewed the guidance contents of algorithm of natural number multiplication in Finland's math textbook and literature. By conclusions, we suggest several implications as followed; First, we need some examples of the way to mark the carrying number in teacher's guidance books and textbooks. Second, teachers try for students to feel the good points of the systematic ways to mark the carrying number. Third, teachers understand algorithm of natural number multiplication and the alternative ways about marking the carrying number.

The smart phone application to provide auto identification and answer explanation of multiple choice answer for each OMR answer item in the test paper different from ordinary OMR test by using smart phone is very useful in terms of a self learning and a smart learning. In this paper, smart phone application of OMR mark identification for each question item in test paper is proposed. QR code for each OMR answer is provided for the encrypted correct answer and the reference location of multiple choice answer rectangle location. The OMR answer region is extracted and the marked answer is identified in each question of test paper, in order to compare between the marking answer and the correct answer. Experimental result of smart phone application of the proposed algorithm for the OMR answer images with various size and direction shows excellent recognition performance.

We analyzed the HACCP prerequisite of National Veterinary Research and Quarantine Service (NVRQS) and the Food Establishment Inspection Report of US Food and Drug Administration (FDA) to recommend contents and ranges to be complemented and used for preparation of guidelines for more effective application of HACCP prerequisites. We used the HACCP inspection reports implemented by Korea Livestock Products HACCP Accreditation Service from 2007 to 2009, FDA Food Code 2009 Guide 3-B Instructions for Marking the Food Establishment Inspection Report, and Retail Food Establishment Sanitation Requirements of 410 Indiana Administrative Code. Major non-compliance items were open doors and windows, insanitary cleaning of in-use utensil, inadequate record of warehousing, and improper storage, transportation, and labelling. Hot water supply, personal hygiene, and regular product testing were additional week points which should be more strongly controlled by detailed operating guidelines. Also, current prerequisite items were required revision into more precise contents to enhanced the effective evaluation and practical application in meat markets.

This study proposes an analysis of the Word2vec-based machine learning classifiers for the sake of opinion mining tasks. As a bench-marking method, BOW (Bag-of-Words) was adopted. On the basis of utilizing the Word2vec and BOW as feature extraction methods, we applied Laptop and Restaurant dataset to LR, DT, SVM, RF classifiers. The results showed that the Word2vec feature extraction yields more improved performance.

Today, we are living in an information era during which we are flooded with information, and it is not an exception also in the magazine field. This study aimed to identify the unique characteristics of magazines by men's magazine companies as research into the big three men's magazines licensed in Korea. Accordingly, concerning a detailed research method, a practical study was carried out on the basis of statistics about the proportion of the contents composition in those magazines. This is because all magazines realize a target point to which their companies aspire, through the contents composition using articles or a pictorial magazine. As a result of thestudy, in the big three licensed men's magazines (Esquire, Arena, and GQ) in Korea, the highest proportion of the contents composition was the proportion of advertising, posting 37.5% on average, which was followed by the proportion of articles or a pictorial concerning fashion, marking 26.8% on average. Therefore, the domestic licensed men's magazines, which were identified by the proportion of the contents composition, were discovered to have thecharacteristics of a fashion magazine. Furthermore, they were found to be published with as lightly different contents composition based on a magazine concept pursued by each magazine company.
