Objectives : This study examined the association between body mass index(BMI) and psychological factors; self-esteem, depression, restraint eating, disinhibition, and hunger. The difference of TFEQ(restraint eating, disinhibition and hunger) was analyzed in variety of current diet situations. Methods : The research was based on a sample of people who visited our website and submit the result of self test(self-esteem n=3183; TFEQ n=5167; BDI n=2457). Results : Self-esteem and BDI was slightly correlated with BMI. There is negative correlation between restraint eating and BMI and positive correlations were observed between hunger and BMI, and disinhibition and BMI. We studied diet situation and eating habits. We divided the sample into 4 groups in accordance with self-submitted result: non-diet group(n=2806), diet-failed group within 3 months group(n=371), maintaining group after successful-diet(n=233), on-going diet group(n=1757) As to restraint eating, non-diet group showed the lowest score in restraint eating and maintaining group after successful-diet showed the highest. The score in disinhibition and hunger was significantly lower in maintaining group after successful-diet group than one in diet-failed group. Conclusion : These results suggest that it would be essential to treat these psychological factors such as depression and self-esteem in weight loss program. Considering the result in diet-situation and TFEQ, we insist that restraint-eating and disinhibition should be controlled. If these psychological factors were not treated in place, even the successful diet might turn out to be a worse situation like binge-eating

In the existing design of web server architecture, data encryption technique is used to keep the reliability, stability, and safety of web service. But the use of data encryption technique wastes the work of cpu while decreasing throughput of web server and increasing average response time so that it shows negative effect on the capacity of web application server. Also, the latest web applications require security and safety for the safe internet communication. Therefore, this paper suggests the improved web server which uses thread pool and Non-blocking I/O adding new web service modules to the existing web server for the safe web service, provides reliability and safety to show the safe web service capacity. And we compare and evaluate the safety and capacity through experiment on the existing traditional Tomcat based web server and the proposed system to evaluate the safety and capacity of the proposed web server system.

Through the systematic analysis on articles about the environment in newspapers, the news reports were considered as effective materials, so after being reconstructed, they were used as learning materials in a lesson on environment contamination which is newly introduced in Earth Science I from the 2009 curriculum revision. To examine students' attitude toward science, before and after NIE application to the students, Test of Science Related Attitudes(TOSRA) as a test tool was carried out which was composed of 7 categories - four optional questionnaires for each category, 28 in total were used. The result was as follows: in a pretest, based upon the average scores by factors the factors ranked from the highest to the lowest as follows: the social meaning of science, the acceptance of the scientific attitude, the commonness of a scientist, the attitude to scientific exploration, the pleasure in science class, the vocational interest in science, the concern over science as a hobby, and in posttest, their ranking as follows: the acceptance of the scientific attitude, the pleasure in science class, the commonness of a scientist, the social meaning of science, the attitude to scientific exploration, the vocational interest in science, the concern over science as a hobby. Also they were all statistically significant at a significant level p<0.05. However, the test revealed that there were some negative effects on the social meaning of science and the attitude to scientific exploration and therefore it is judged that in order to overcome those influences, some bright articles about solving the environment contamination should be applied to the lessons and be complemented effectively by experiments and various media: NIE as well as science magazines, data from Internet search and treatises on science.

This study was done to analyze the consumption patterns of health functional food (HFF) as well as to perform needs assessment for the development of web-contents on HFF according to age of adults. The subjects were 238 male and female adults, divided into 4 groups by their age. This study collected all information by self-administrated questionnaires. The awareness on HFF was high in the older adults. The younger adults showed more negative responses to reliability and safety on HFF. The main reason for the consumption of HFF was to supplement nutrients and to prevent diseases. The main types of HFF consumed by adults were nutritional supplementary food, red ginseng products, and glucosamine products. There was higher consumption of nutritional supplementary food in the younger adults and glucosamine products in the older adults. Internet users had low level of satisfaction, with tendency to complain poor contents, reliability, difficulties in searching as problems of the pre-existing HFF websites. As useful methods for provision of information on HFF, most adults wanted general information, articles written by experts and videos. They also wanted to know the safety and side effects of HFF. Requirement of contents composition were various in-depth information, clear indication of citation, fresh updated data while that of display composition was easily-findable, uncomplicated, allowing mutual exchange of communication through bulletin board. These results can be used as basic data that reflect the consumer's needs for developing HFF web-contents according to age of adults.

Digital Contents are increasing the modification of the contents by individual user and the modified or copied contents are simply distributed though the ultrahigh speed internet and the negative pervasive effect on the contents market is increasing. The solutions for copyright protection from illegally distributing contents are developing by various standardization groups and contents manufacturers and its commercia use is partly practiced. The MPEG was developing the IPMP technique to apply existed MPEG standards as a way of digital contents protection. However, as these IPMP techniques did not provide a satisfactory function for contents protection, the DMP standard was suggested as an alternative plan. In this paper, the system is designed and materialized to apply the TooIPack concept of DMP which ensure the interoperability of DRM system. With this paper, it is expected that the practical use and the possibility of the DMP standard in the DRM market would be verified and DMP standard may presents as a reference model for more systematic standardization operations.

The purpose of this study was to explore the moderating effect of food safety scandals on the relationship between food company's Corporate Social Responsibility(CSR) engagement at different levels and brand image in the Chinese dairy company context. In addition, this study also examined the mediating effect of brand image on CSR engagement and consumer loyalty. The study adopted a $2{\times}2$ between-subjects experimental design using scenarios. Four scenarios provided a mixed combination of yes or no cases for food safety scandal, and high or low cases for a dairy company's CSR engagement. In this study, survey was used to collect data from Chinese consumers. Of these, 377 valid data were collected from a sample of average Chinese consumers over the age of 20, collected through the internet. The results show that CSR engagement at different levels has a significant effect on brand image and food safety scandal has a significant moderating effect on the relationship between the two. This study expanded the previous study on the sensitivity of consumers to CSR activities in eastern China. At the same time, according to the results of the study, different CSR engagement of food enterprises does have a significant impact on brand image and consumer loyalty. In particular, high CSR engagement reduces negative impact on brand image through the moderating effect of food safety scandals. Therefore, for food business managers, actively participate in CSR activities, and actively enhance the engagement has a significant influence on the management of brand image.

Objectives: The aim of this study was to assess knowledge, attitudes, and practices regarding tuberculosis (TB) in the general population in Timor-Leste. Methods: In the nationally representative cross-sectional 2016 Timor-Leste Demographic and Health Survey, 4622 men (aged 15-59 years) and 12 607 women (aged 15-49 years) were randomly selected using stratified multistage sampling and interviewed. Results: Overall, 66.9% of men and 62.8% of women were aware of TB, 4.4% of men and 12.6% of women had TB courtesy stigma, and 83.3% of men and 88.6% of women reported intention to receive TB treatment. The $mean{\pm}standard$ deviation overall TB knowledge score was $3.9{\pm}2.0$ (out of 8) among men and $3.0{\pm}1.8$ among women. In a multivariable linear regression analysis, among both men and women, older age, higher education, rural residence, and sources of TB information (family/friends, school/workplace, health care provider, Internet, television, and newspaper) were associated with higher TB knowledge scores. In addition, among women, higher wealth status and having heard about TB from the radio were associated with higher TB knowledge scores. Negative associations with TB courtesy stigma were found for urban residence and having heard about TB from family or friends among men, and for older age, higher TB knowledge, and TB information sources (family/friends and school/workplace) among women. Among both men and women, higher TB knowledge scores and having heard of TB from a health care provider were associated with intention to receive TB treatment. Conclusions: This study identified socio-demographic risk factors for deficiences in population-based TB knowledge in Timor-Leste; these findings should be considered when designing TB communication, prevention, and control strategies.

This study was proposed to examine the mediating effect of basic psychological needs on how parenting attitude affect middle school students with over-dependence on smart phone. This study utilized 2017 survey research by National Information Society Agency (NIA), namely a long-term follow-up study of 901 people with over-dependence on internet and smart phone. This study showed two findings. First, over-dependence on smart phone had correlations with basic psychological needs- autonomy(r=-.22, p<.001) and competence(r=-.13, p<.001); with parenting attitude- positive parenting(r=-.21, p<.001) and negative parenting(r=.15, p<.001). Second, both parenting attitude and basic psychological needs had a causal relationship with over-dependence on smart phone. These results can provide a basis to reconsider social awareness on over-dependence on smart phone among middle school students. This study proposed few research directions for further study to prevent over-dependence on smart phone and to educate parents.

Low power issue is one of the most critical problems in the Internet of Things (IoT), which are powered by battery. To solve this problem, various approaches have been presented so far. In this paper, we propose a method to reduce the power consumption by reducing the numbers of accesses into the flash memory consuming a large amount of power for on-chip software execution. Our approach is based on using cooperative logging structure to distribute the sampling overhead in single sensor node to adjacent nodes in case of rare-event applications. The proposed algorithm to identify event occurrence is newly introduced with negative feedback method by observing difference between past data and recent data coming from the sensor. When an event with need of flash access is determined, the proposed approach only allows access to write the sampled data in flash memory. The proposed event detection algorithm (EDA) result in 30% reduction of power consumption compared to the conventional flash write scheme for all cases of event. The sampled data from the sensor is first traced into the random access memory (RAM), and write access to the flash memory is delayed until the page buffer of the on-chip flash memory controller in the micro controller unit (MCU) is full of the numbers of the traced data, thereby reducing the frequency of accessing flash memory. This technique additionally reduces power consumption by 40% compared to flash-write all data. By sharing the sampling information via LoRa channel, the overhead in sampling data is distributed, to reduce the sampling load on each node, so that the 66% reduction of total power consumption is achieved in several IoT edge nodes by removing the sampling operation of duplicated data.
