The purpose of this study was to do the quantitative analysis about food and nutrition informations in TV program by monitoring newscastings, health-related food and nutrition information programs, dramas for family, education programs for children, and seniors’ information programs in major TV broadcasting companies (KBS, MBC, SBS, EBS). In this study, number of cases about the health-related food and nutrition informations and the length of program were analyzed. Also, they were compared and analyzed by the year. Monitoring staff, who had majored in food and nutrition and completed the monitoring training, monitored programs and analysis the quantity of food and nutrition informations in each program from 2002 to 2003. Results of quantitative analysis for this study are as follows; There were total number of 15,226 cases. Among them, the total number of health-related information was 5,623 cases(36.9%), and the total number of food-related information was 3,848 cases (25.3%). The ratio of total food and nutrition information to total health-related informations was 86.2%. In news programs from 2002 to 2003, the total number of health-related information to total cases decreased to 16.1% from 17.9%. The ratio of total food and nutrition information to total cases decreased to 3.6% from 6.6%. The frequency of the health-related informations was mostly served in the newscastings was highest, in both October 2002, and September 2003. In health information programs from 2002 to 2003, the ratio of food and nutrition information to total cases increased to 57.4% from 32.4%. In dramas from 2002 to 2003 , the ratio of broadcasting time of food-related scenes to total cases decreased to 17.2% from 20.8%. In education programs for children the ratio of food and nutrition information to total cases was 8.2% in 2002. In information programs for seniors the ratio of food and nutrition information was to total cases 26.2% in 2002. As the result of this study, the rate of health-related information in TV program and the rate of food and nutrition information were changing. And the rate of nutrition information in health information programs are increased. To give sound informations to the public, monitoring should be established and managed continuously.

The purpose of this study was to analyze information about food and nutrition presented through the television broadcast media, with the aim of finding out the optimal communication method for supplying the general public with accurate information. To perform this study, a total of sixteen monitoring people were recruited and trained before and during the study. Five domestic TV channels were selected to be monitored, and the total monitoring period was six months. For maximum efficiency, the monitoring people were assigned to 8 teams. The results of the present study can be summarized as follows : First, the total reported cases of information about food and nutrition were 237, of which about 30% were judged appropriate and 70％ as inappropriate. Second, classifying each case by program type, information programs made up the highest portion at 82 cases (34.6%), cooking programs accounted for 76 cases (32.1%), news programs for 40 cases (16.9%), and entertainment programs for 7 cases (3.0%). The analysis showed that the greatest amount of incorrect information was found in dramas, followed by entertainment, information, cooking and news programs. Third, classifying each case by theme of contents monitored, meal preparation and cookery made up the highest portion at 86 cases (36.3%), foods accounted for 67 cases (28.3%), disease and diet-therapy for 40 cases (16.9%), eating habits for 31 cases (13.1%), and diet and fitness for 13 cases (5.5%). Incorrect information was conveyed most often on the themes of food habits, foods, disease and diet-therapy, cookery, and diet and fitness. Fourth, classifying each case by channel, Cable TV had the highest frequency at 72 cases (30.4%), MBC had 51 cases (21.5%), SBS had 43 cases (18.1%), KBS1 had 41 cases (17.3%) and KBS2 had 30 cases (12.7%). In conclusion, systematic monitoring should be continued to reduce the frequency of incorrect information being broadcast and to help ensure that accurate information is conveyed to the general public. Moreover, there should be a system of cooperation to provide information to help broadcast production teams establish a strategic program. Finally, it is essential to organize an advisory team by promoting links between the mass media and specialists in the field, and to develop an educational program on nutrition to help ensure the communication of accurate information on food and nutrition.

A method is applied for the estimation of structural damage of tall slender structures using natural frequency and displacements measurements by GPS. The relationship between the variation in the global stiffness matrix (or in the stiffness of each finite element) and the change in the natural frequencies of the structure is given. In engineering practice the number of frequencies which can be derived by GPS measurement of long-period structures will be equal to one, two or three first natural frequencies. This allows us in initial studies to detect damage with frequency changes based on forward methods in which the measured frequencies are compared with the predicted analytical data. This idea, of health monitoring from possible changes to natural frequencies, or from a statement of excessive displacements is applied to the Stuttgart TV Tower.

Properties of multivariate Shewhart and CUSUM charts for monitoring variance-covariance matrix, specially focused on correlation coefficient components, are investigated. The performances of the proposed charts based on control statistic Lawley-Hotelling $V_i$ and likelihood ratio test (LRT) statistic $TV_i$ are evaluated in terms of average run length (ARL). For monitoring correlation coe cient components of dispersion matrix, we found that CUSUM chart based on $TV_i$ gives relatively better performances and is more preferable, and the charts based on $V_i$ perform badly and are not recommended.

The number of channels are increased into several hundreds of channels when coming out the digital broadcasting era. In this environment, viewers searching for programs will be very difficult to do. In addition, recent popularization of smart devices are receiving the services that they previously had not been given to. A TV program recommended a system that has been studied as a way to solve these problems. However, most studies have been studied in most web-based research results when applied to broadcast TV for TV program recommendations. In particular, the combination of the current members who watch TV are not considered. In this paper, the environment and TV viewers are considering a combination of the members of the TV program's recommended system proposal. In order to make a group deal successful, we employ the face recognition.

Objectives: Television is the most influencing mass media. It has taken an important part in our daily life as the information source. Transmitted informations are the important sources for building one's conscience, value and behavior for all age groups from young children to aged. Methods: In this paper, all land-based TV programs for young children has been monitored by quantity and quality from July 1st 2008 'till December 31st. General programs for young children have been monitored by its theme, type, contents delivery method, proportion of diet and health information in the program, and appropriateness. For the analysis, SPSS was used. Results: Young children's program 2,771 programs and 47,169 minutes during the period were monitored. From programs for young children about 'general' and 'cooking', there were 48programs(30.6%) that has contents about dishes, 47programs(29.9%) about food and nutrition, 34programs(21.7%) about life habits. From the programs, diet and health has been delivered by 'practical exercise(38.9%)', by 'cartoon & puppet show(31.2%)', followed by 'explanation from experts(15.3%)', 'song & movement(8.9%)', and 'simple introduction(4.4%)'. From programs for young children about 'general' and 'cooking', there were 157programs that has contents about ideas and delivery method being considered, 'appropriate(45.7%)' for giving positive and 'inappropriate(54.3%)' for its negative influence to young children, the need of improvement was suggested. Conclusion: Considering the importance of infancy in one's lifetime, not only specific field but each program for young children itself should be monitored by experts of each field. A plan on how to deliver accurate content effectively to young children should be searched in various ways.

The study aimed to perform the qualitative analysis of food and nutrition informations offered in TV program by monitoring newscastings, health-related programs giving food and nutrition information, dramas for family, education programs for children, and information programs for elderly in major TV broadcasting station(KBS, MBC, SBS, EBS). In this study, statistical analysis were done for numbers of information items related to health or food and nutrition informations. Duration of program the main, subject, sources, evaluation criteria of the contents. Results of qualitative monitoring for TV program are as follows. For health-related informations major propotions of subjects for the newscastings were about diseases. Those for health information programs were about foods. Those for children-education programs were about groceries. Those for seniors’ information programs were about eating habits. The analysis of food and nutrition information sources for most of programs were interviews with specialist and normal person, and on-the-spot-investingations. For food and nutrition informations those were evaluated as inappropriate, the propotion of news was increased to 72.2% in 2003 from 49.3% in 2002. For health information programs, it was increased to 67.7% in 2003 from 54.0% in 2002. But, in drama the propotion of inappropriate scenes were decreased to 16.2% in 2003 from 63.2% in 2002. In children-education programs, it was 40.0%. In seniors’ information programs, it was 17.9% in 2002. The propotion of cases that the quantity of foods is inappropriate in the food scene of serial drama, decreased to 15.8% in 2003 from 28.6% in 2002. The rate of drinking scenes increased to 11.5% from 10.7%. The rate of smoking scenes decreased to 0.2% from 1.6% due to the broadcasting self-regulation of smoking scenes in dramas. In the newscatings and information programs, reasons of being evaluated as inappropriate was that they didn’t have any practical suggestions and proper intakes. There were also insufficient explanation for technical terminology, different comparison standard of nutritive value, and exaggeration for physiological effect of food. The drama contained a lot of unnecessary scenes of alcohol drinking, coffee drinking, midnight meal, and had more quantity of foods than the quantity needed for persons to the scene. As the result of this study, the rate of food and nutrition information were high, but the rate of information which was evaluate as appropriate was not sufficient. There are need to improve contents of information and to moniter the contents for consumer.

This paper considers a power saving technique of set-top box (STB) that turns the signal into content which is then displayed on the television (TV) screen. A traditional power saving scheme, Auto Power Down (APD), was devised to reduce the power consumption of STB. APD checks whether the user is watching TV over a period of time and enforces STB into stand-by mode when the check result reveals the user is not watching TV. This paper proposes an enhanced power saving scheme that transits STB operation mode to 'stand-by' immediately when STB recognizes the change of TV's external input signal. The proposed scheme does not require the monitoring time to check the users' watching TV, and transits to standby mode faster than the conventional APD, which results in better performance in power saving. The simulation result shows that the proposed scheme achieves 2 to 11% improvement in power consumption compared with the conventional APD.

The 610 m high Canton Tower (formerly named Guangzhou New Television Tower) is currently considered as a benchmark problem for structural health monitoring (SHM) of high-rise slender structures. In the benchmark study task I, a set of 24-hour ambient vibration measurement data has been available for the output-only system identification study. In this paper, the vector autoregressive models (ARV) method is adopted in the operational modal analysis (OMA) for this TV tower. The identified natural frequencies, damping ratios and mode shapes are presented and compared with the available results from some other research groups which used different methods, e.g., the data-driven stochastic subspace identification (SSI-DATA) method, the enhanced frequency domain decomposition (EFDD) algorithm, and an improved modal identification method based on NExT-ERA technique. Furthermore, the environmental effects on the estimated modal parameters are also discussed.
