In this study, based on SSOP (Sanitation Standard Operating Procedure) for HACCP in Food Sanitation Act, essential facility, equipment and documentary records for HACCP implementation were identified. Usage and adoption of these devices at Korea Food ＆ Drug Administration appointed HACCP foodservices ("Appointed"), voluntary HACCP applying foodservices ("Voluntary applying") and HACCP non-applying foodservices ("Non-applying") have been compared. Total 46 contract foodservices were surveyed： 13 "Appointed" (65％ of nation-wide all appointed food services in February, 2002),17 "Voluntary applying" and 16 "Non-applying". For usage and adoption of facility and equipment, 18 out of total 27 surveying items showed significant differences at the three foodservice groups (p＜0.01 or p＜0.05). Specifically, following items showed lower usage than 70％ in the "Appointed"： ′A trench including grease trap′, ′3-compartment sink with hot water′. Regarding CCP monitoring tool installation, 8 out of total 9 items showed significant differences among the groups (p＜0.01 or p＜0.05). For the usage of 10 documentary recording items for HACCP application log, 7 items showed significant differences among the groups (p＜0.01 or p＜0.05). Resultantly, most of those essential facilities, equipment and documentary records ;were used only in the "Appointed". The limited usages of those were showed for the "Voluntary applying" where the dietitian answered they applied HACCP voluntarily. The "Non-applying" didn′t have many surveyed items.

As an useful application in broadcasting services, the targeting service has been mainly studied to improve the service satisfaction and user usage in various media service environments based on user profile, preferences, and usage history. Targeting service is expanding its domain from broadcasting contents to interstitial contents and from fixed TV devices to mobile devices. Service data also include advertisement data, coupon, and information about media contents as well as simple broadcasting data. In this paper, the targeting data service is designed and implemented on articles, advertisement and broadcasting information on the basis of the user information. To adapt this to web-based media contents, information on user profile, preferences, and usage history is newly defined on the basis of the user metadata developed in TV-Anytime Forum and the user information defined in OpenSocial. The targeting data service is implemented to generate user preferences information and usage history pattern based on the similarity among user preference, contents information, and usage history. Based on performance evaluation, we prove that the proposed targeting data service is effectively applicable to web-based media contents as well as broadcasting service.

A survey performed on property of water usage, a recognition and stand on water, and awareness of practice related to water saving among primary and secondary teachers in Daegu metropolitan city leads to the following result. First, regarding the actual condition of water usage, boiled tap water was most preferred, followed by purified tap water, mineral water, and water from a mineral spring respectively. Second, the result of a survey regarding a recognition and stand on water presents that the quality of purified water and mineral water is generally trusted, not including tap water. A majority of teachers barely had any ideas on the process of tap water supplies and sewage disposal system. Third, another survey was performed to determine whether there's a gender difference on a general recognition of and stand on water usage, actual practice of water saving and love for water. As a result, 7 out of 25 questions showed the difference of significance by p<.05. As for tap water service and sewage disposal system, there were differences on 5 out of 6 questions, indicating that male teachers are more knowledgable than their female counterparts. Fourth, the result of the research about the recognition and attitudes about water and water saving of the teachers who were categorized by the age group showed that 14 questions of the 25 questions had differences in p<.05 level. Teachers in their twenties and thirties had less interest than those in their forties and fifties.

As the importance of intellectual property rights for the 21st century challenge became prominent, many companies have been trying to secure many rights competitively. In particular, application numbers of patent that represents technology has been increased continuously. Korean companies were not exception; mainly in large companies, there have been continued the efforts to grow the number of patent applications in quantitative volume. But the issues that how viable patents the companies have, how effectively the companies manage, and how economically usable the patents are, are totally different from quantitative management level. As such, the issue is connected to how to assess the patent management level of companies. On the other side of quantitative growth of patent that companies hold, there are some problems such as the difficulties to determine if the patents hold substantial values, and the difficulties to determine whether the patent are managed effectively. In addition, as the numbers of patent application and registration of companies are increased, the cost for patent holding and managing increase. It is required to pay continuous attention to the cost of patent management because patent registration fee has a property that increases rapidly with time and burden for patentee become heavier. As a result of analysis and interpretation, we confirmed that quantitative management, particularly the number of patent applicant does not make positive impact on how to use patent after application. Rather, it is observed that the economical usage is influenced positively by the efforts of patent applicants such as considering for the time of patent examination, paying attention to receive patent registration decision. Therefore, this study shows that efforts patent applicants provide in management level after application time are important to maintain the value of patents.

Background: The use of radiation and radioisotopes in Korea has been increasing each year, and its impact on economy and industry is expected to be increasing progressively following the development of industrial technology and the expansion of their usage. To establish and supporting policies for industries using radiation and radioisotopes, it is necessary to check the status of related industries accurately, as well as to gather data required to establish plans for industrial development by studying both revenues and economic scale (contributing to revenue). Materials and Methods: To analyze the status of utilization, surveys were carried out on 6,621 organizations engaged in nuclear operations handling radiation and radioisotopes pursuant to the Nuclear Safety Act as of end 2014, on 33,471 medical institutions using radiation generators for medical and diagnostic purposes pursuant to the Medical Service Act, and on 2,218 organizations using radiation generators for animal diagnostics pursuant to the Veterinary License Act. Results and discussion: The overall status of the domestic radiation market including the number of user organizations, that of employees, and the size of distributions (imports, productions, and exports) with which the scale of domestic radiation market can be judged showed a growth trend compared to the previous year, though the number of employees for radiation operation in industrial sector, research sector, education sector, military sector, and power plants (nuclear power plants) and the size of imports was reduced somewhat. Conclusion: It is expected that data acquired through periodic surveys on the status of utilization would be utilized practically in establishing governmental policies related to the promotion of usage of radiation and radioisotopes, and also be utilized widely in cultivating and developing the industry efficiently to invigorate the related industries.

This research was conducted to investigate the effect of foliar application of 6-benzylaminopurine (BA), sprayed weeks after pinching (SWP), on ornamental usage of Veronica longifolia L, which is native to Korea. Foliar application of 0, 500, 1,000, and 2,000 mg/L BA on 10 cm long V. longifolia L. plant was evaluated at 0, 7, and 14 days after pinching for growth and flowering. The maximum result of multiple shooting was seen in the 2,000 mg/L BA at 1 week after pinching, and almost all the treatments showed dwarf growth in V. longifolia L. The number of days to flowering was delayed by BA treatments. Moreover, the length and the number of flowers decreased with high concentrations of BA. Thus, foliar application of BA via pinching technique can improve the ornamental usage of V. longifolia L. by controlling the plant type.

This paper presents a critical analysis of the current application of big data in higher education and how Learning Analytics (LA), and Educational Data Mining (EDM) are helping to shape learning in higher education institutions that have applied the concepts successfully. An extensive literature review of Learning Analytics, Educational Data Mining, Learning Management Systems, Informal Learning and Online Social Networks are presented to understand their usage and trends in higher education pedagogy taking advantage of 21st century educational technologies and platforms. The roles of and benefits of these technologies in teaching and learning are critically examined. Imperatively, this study provides vital information for education stakeholders on the significance of establishing a teaching and learning agenda that takes advantage of today's educational relevant technologies to promote teaching and learning while also acknowledging the difficulties of 21st-century learning. Aside from the roles and benefits of these technologies, the review highlights major challenges and research needs apparent in the use and application of these technologies. It appears that there is lack of research understanding in the challenges and utilization of data effectively for learning analytics, despite the massive educational data generated by high institutions. Also due to the growing importance of LA, there appears to be a serious lack of academic research that explore the application and impact of LA in high institution, especially in the context of informal online social network learning. In addition, high institution managers seem not to understand the emerging trends of LA which could be useful in the running of higher education. Though LA is viewed as a complex and expensive technology that will culturally change the future of high institution, the question that comes to mind is whether the use of LA in relation to informal learning in online social network is really what is expected? A study to analyze and evaluate the elements that influence high usage of OSN is also needed in the African context. It is high time African Universities paid attention to the application and use of these technologies to create a simplified learning approach occasioned by the use of these technologies.

As the Internet is quickly evolving from best-effort networks to business quality networks, billing based on the precise traffic measurement becomes an important issue for Internet Service Providers (ISPs). Billing settlement is necessary not only between ISP and customers but also between ISPs. Currently, most ISPs use a flat rate charging policy. Besides the degree of difficulty in deriving appropriate charging policies agreeable by a concerned party, there are substantial technical challenges to come up with a good usage-based accounting system. Usage-based accounting depending on IP packet header information only is not sufficient anymore due to highly dynamic nature of the development and the use of the Internet applications such as peer-to-peer and network games. They are using port numbers dynamically and even several applications can use the same port number. Thus, more precise means of classifying them and accounting their traffic usages are required. In this paper, we propose a high performance, adaptable, configurable, and scalable content-aware application traffic measurement and analysis system which can achieve very accurate usage-based accounting.
