Processing methods of heat treatment in milk has been developed to increase safety for the consumer by destroying pathogens that may be found in milk. Commercial pasteurization of milk in the market started in the late 1800s in Europe and in the early 1900s in the United States. In 1962, it became a requirement in Korea that all milk for sale should be treated by heat. Nowadays, heat treatment (pasteurization or sterilization) became mandatory for all milk products sold in all over the world. However, since 1987, there was a big debate about the heat-treatment of milk. Korea Society of Dairy Science and Technology (KSDST) complied the 10 scientific articles of milk heat-treatment into the book which titled "Effects of the heat-treatment on the nutritional quality of milk". Almost several hundred copies had been distributed at the symposium KSDST in 1989. Currently, no one was able to find these articles in anywhere including library etc. Thus, author decided to re-write that books in serials because these articles should be pass on their knowledge of milk science to the next generation of milk research.

Give that statistical analysis is an essential component of foodservice-related research, the purpose of this review is to analyse research trends of statistical methods applied to foodservice-related research. To achieve these objective, this study carried out a content analysis on a total of 251 out of 415 research articles published in The Korean Journal of Culinary Research(TKJCR) from January 2010 to December 2013. Of the total 164 research articles focussing on natural science research, qualitative research, articles written in English were excluded from the scope of this study. The results of this study are as follows. First, it turned out that 269 research articles applied quantitative research methods, and only 10 articles applied qualitative research methods among the 279 research articles based on social science research methods. Second, 20 article (8.0%) among the 251 did not specify the statistical methods or computer programs that were used for statistical analysis. Third, it was found that 228 articles (90.8%) used the SPSS program for data analysis. Fourth, in terms of frequency of use, it was revealed frequency analysis was most used, followed in order by reliability analysis, exploratory factor analysis, correlation analysis, regression analysis, structural equation modeling, confirmatory factor analysis, t-test, variance analysis, and cross tabs analysis, However, 3 out of 56 research articles that used a t-test did not suggest a t-value. 10 out of 64 articles that used ANOVA and demonstrated a significant difference in between-group mean did not conducted post-hoc test. Therefore, the researchers with interest in foodservice fields need to keep in mind that choosing and applying the correct statistical technique both determine the value and the success or failure of a study. To enhance the value and success of a study, it is necessary to use the proper statistical technique in an efficient way in order to prevent statistical errors.

Annually more than three hundred thousand lost articles are found in Korea. These articles are only being nuisances kept in lost-and-found centers and storing them consumes a considerable amount of costs. In this paper, we developed a mobile application that helps to find lost articles quickly by using NFC which is the next generation short-distance telecommunication technique. We aim to increase NFC utilization that at this time is only used in limited areas such as public transportation card and Smart Wallet. In addition to this, we seek to reduce the cost for keeping annually lost articles as well.

Scholarly communication plays a significant role in the development and dissemination of research outputs in library and information science (LIS). This study presents findings from a survey which examines the key attributes that characterize the publishing by Pakistani LIS scholars, i.e. academics and professionals, in national journals. A pilot-tested, electronic questionnaire was used to collect the data from the target population. 104 respondents (or 69.3% of target) provided feedback on areas such as number of articles published, number of citations, and the nature of any collaboration with other authors. The findings of this survey revealed that, among the various designated regions of Pakistan, the Punjab region was the most highly represented. In articles published in national journals, there was a clear preference among all respondents to collaborate with at least one other author. The citation metrics for LIS articles in national journals were relatively low (30.22%), which aligns with Scimago’s Journal and Country Rankings. The uptake of social scholarly networks mirrors international trends. Respondents were asked to score factors which could impact negatively on their ability to undertake research and/or publish the results. The study recommends that concerned stakeholders work together, as appropriate, to address concerns. In addition, it recommends that further research be undertaken to define patterns of Pakistani co-authorship in the social sciences.

Nowadays many articles describe the controlling models for four rotor flying vehicle. Basic approaches to the problem of these articles are mathematical expressions describing dynamics of the models of the vehicle and PID control for manipulating the object in 3 dimensional space. Design of control systems is usually started by careful consideration of its mathematical model description. We present a detailed mathematical model for a quad rotor. This paper first considers simulation of quadcopter control based on full state feedback technique with linearization in MATLAB environment and shows the results of the simulations. Finally will be shown experimental results of the state feedback control implemented in real model.
