The purpose of this report is to present a list of Korean foods containing histamine, that is known to cause food allergy and chronic urticaria. For the measurement of histamine in foods, the application of spectrofluorimeter is used. Among the food groups, sea foods (mackerel, pacific saury, spanish mackerel, anchovy, hair, tail, tuna) contain most high amount of histamine, and the contents of see weeds (sea mustard, laverare) are also high. Milk and milk products (mozzarella cheese, yogurt) contain more histamine than animal meats. Plant foods like cereals, vegetables or fruits contain much less histamine than other food groups, except spinach. The contents of dried sesame, sesame oil, and mugicha, green tea, ginseng tea, mayonnaise, tomato ketchup are relatively high. This paper will be used as a fundamental guideline in planning dietary management of allergy and for the operational plans for the future nutrition education intervention. Because the foods rich in histamine may cause allergy-like syptoms, it may be reqoiled to label the foods containing histamine.

The dietary fiber and crude fiber contents of different thallus regions (blade, stipe, and holdfast) in three brown algae (Laminaria japonica, Ecklonia stolonifera, and E. cava) were detennined at different ages, and then compared with one another. On a dry matter basis, the soluble dietary fiber (SDF) content was highest ($10.8{\pm}0.5%$) in the holdfast of 2-year old L. japonica, and the insoluble dietary fiber (IDF), total dietary fiber (TDF), and crude fiber (CF) contents were highest in the holdfast of 2-year old E. cava at $44.5{\pm}0.7%$, $50.2{\pm}0.5%$, $6.8{\pm}0.7%$, respectively. The IDF, TDF, and CF contents of these three species were measured in the following order: holdfast > stipe > blade, and the SDF contents of L. japonica exhibited the reverse of this trend. The TDF/CF ratio of 1-year old L. japonica, E. stolonifera, and E. cava was greater than was observed in the corresponding 2-year old samples. This is, to the best of our knowledge, the first report demonstrating that the holdfasts of L. japonica, E. stolonifera, and E. cava are rich in dietary fiber contents, especially IDF, TDF, and CF.

Recently, as the use of the Internet and the Web becomes universal, there has been a great deal of efforts to use it for education among educators throughout the world. The advantage of a Web-based lecture is that people can take it anywhere at a low cost anytime. The demand for learning java programming using the Web is increasing. Accordingly, a number of Web-based Java programming course contents have developed and used. Problems with existing contents are that materials about how to program are not sufficient and the presentation of the lecture is most often separated from the programming environment. In this paper, we present a methodology for developing course contents of Java programming to solve these problems and develop them using it. Then we report the evaluation result of course contents by students who took a Web-based lecture using them.

This thesis is a content analysis on whether the proportion of structural element and theme association of television news imagery is different, depending on the historical background, and on what it means, which can be the index of scene-based and realistic report. Most researches of television news are horizontal studies of the same period, making light of vertical studies reflecting the change of age. Therefore, This study analyzed 729 items composed of 11,945 shots extracted from MBC Newsdesk from 1987, to 2007, the samples of which were extracted by systematic random sampling with five years' interval. This content analysis found out that there was high proportion of scene-based and realistic report such as 'sound-bite', 'event footage', 'direct matching' in the year 1987, 2007, and high proportion of 'corroboration shot', 'file footage', 'indirect reference', 'literal matching only' in the year 1997, which revealed the fact that reality-based report had not been faithfully accomplished in 1997.

The study was intended to identify the factors that affect pediatric nurses' perception toward child abuse and their reporting attitude. The report rate was very low, only 3 (9.1%) of respondents. Most of them did not report, 30(90.9%), and the main causes of non-reporting were not-serious or lack of evidence. The recognition and experience of child abuse depending on the characteristics of nurses in pediatric wards showed a significant difference according to their academic background (X2=16.52, p=.011). The results of the review of the differences in the reported attitudes of child abuse nurses showed a significant difference in the age of nurses in the pediatric ward (X2=13.64, p=.034). Nurses in the pediatric ward are required to develop intervention programs and tools for assessing child abuse, and to provide education and systems for the prevention of child abuse, which will make it necessary for the universal reporting of cases against child abuse and the prevention of child abuse.

There has been growing academic interest in revealing the effect of 3D stereoscopic displays, mostly based on the assumption that 3D would enhance the media user's psychological experiences. A 2(Display: 2D, 3D) x 2(Arousal: High, Low) x2(Valence: Positive, Negative) within-between subject experimental design, including both psychophysiological and self-report measurements, was employed to investigate if valence and arousal of the media content interact with the 3D stereo display. The results confirmed that 3D stereo significantly enhances the viewer's skin conductance level, while no meaningful difference for HR was found across the experimental conditions. The viewer's recall memory did not differ depending on the display type either. However, the viewer experienced a greater level of presence and liking of the content when the negative content was displayed in 3D stereo in comparison with the positive content. The practical implications of the results are further discussed.

To provide real-time traffic conditions, crowd sourcing based traffic information services in which users directly report and share traffic conditions are being developed. However, the existing traffic information service provides limited traffic conditions because it only shares information reported by specific service participants. In this paper, we design and develop a crowd sourcing based traffic information service that provides real-time traffic conditions by collecting direct reports from users and public traffic conditions. The proposed service allows users to directly report traffic conditions by voice and text, and collects and integrates traffic conditions published by external organizations. The collected traffic conditions are provided in real time through a push service, and new traffic conditions are transmitted when the user's location changes. The proposed service can report traffic conditions and share real-time traffic conditions through an Android app.

This article described relations between knowledge contents for culture contents. Knowledge contents include academic article, research report, digital replica for old books and digital cultural heritages with a high level of abstraction and complexity. The process of digitalization sets up the clearinghouse for information and knowledge of humanities which can be a critical resource for cultural contents development. Knowledge contents are deliverable of knowledge-information hierarchies. The knowledgeinformation resource management plan doing by Korean Studies Advancement Center shows the most of the hierarchies. As a result, this paper shows that the process of knowledge-information development and the process of cultural contents development are in a series of continuous process.With the help of information technology.

This study has developed a preventive launcher from smartphone addiction for the digital generation and the contents recommendation based on machine learning which used multiple and collective intelligence. This could provide convenient digital nurturing experience for the parents who fear their children's over use of digital devices and also suggest individually adaptive digital learning methods that enhance the learning efficiency and pleasurable and safe learning environment for the children. Suggested application is a kind of gamification launcher that protects children from harmful contents and from smartphone addiction with time limit settings. For parents who find difficulty choosing from various kinds of contents and applications for education, this suggested system could provide a learning analytic report based on big data after collecting and analyzing the data of their children's learning and activities and recommend contents necessary for their kids using recommended algorithm by collective intelligence.

Benzo(a)pyrene [B(a)P], one of the polycyclic aromatic hydrocarbons(PAHs) is know as a potent careinogen. As consumption of lipid food and fried food increases recently, the toxic effect of overheated lipid foods has report increasingly. This study was undertaken to measure the contents of B(a)P and other PAHs of fried chicken and frying oil. At the same time, the rancidities of frying oil and descarded oil were determined. B(a)P and other PAHs contents of all samples were measured by HPLC/UV method. The results obtained were as follows; B(a)P contents of fresh chicken and soybean oil were 0.073 and 0.146 ${\mu}$g/kg, respectively. During fried chicken at 180${\pm}$5$^{\circ}C$ and 200${\pm}$5$^{\circ}C$, B(a)P and PAHs contens decreased or increased In 20 times fried chicken, PAHs contents except Pyr and DMBA increased at 180${\pm}$5$^{\circ}C$ and PAHs contents except DMBA, DBA, and 3-MC increased at 200${\pm}$5$^{\circ}C$. In frying oils fried chicken, PAHs contents increased in 10 and 15 times frying oil at 180${\pm}$5$^{\circ}C$ and grew more increase and more increase during frying at 200${\pm}$5$^{\circ}C$. The changing pattern of PAHs contents of frying oils was remotely related that of rancidities of frying oils. In fried chicken, frying oils, and discarded oils obtained from fried chicken house at market, PAHs contents of fried chickens were lower than those of fried chicken cooked at laboratory but those of frying oils and discarded oils were higher than those of frying oils cooked at laboratory.
