The purpose of this study was to investigate the perception and willingness to purchase of nanotechnology-based foods to find out the strategy for risk communication and social acceptance. The data were collected from 253 college students in Yeungnam region through a self-administered questionnaire. Frequency, Cronbach's ${\alpha}$, t test, one-way ANOVA, Duncan's multiple range test, Pearson's correlation coefficient analysis, and multiple regression analysis were conducted by SPSS Windows V.20.0. The level of concern about nanotechnology was relatively low, and the level of the perception about necessity for the development of nanotechnology-based foods was average. In addition, the respondents showed somewhat positive thoughts for the development of nanotechnology-based foods with beneficial effect, but they were worried about the risk for it. Percentage of correct answers on knowledge of nanotechnology and nanotechnology-based foods was not high, and the level of willingness to purchase them was average. According to the result of multiple regression analysis, factors affecting the willingness to purchase of nanotechnology-based foods were concern about health, perception about importance of food safety, perception about necessity for the development of nanotechnology-based foods, and perception about the development of nanotechnology-based foods with beneficial effect. On the basis of these results, it is necessary for consumers to offer the exact and reliable information on nanotechnology-based foods.

The number of cyclists is on the steady growing for leisure and transportation with the increasing interest in health and environment. However, the number of cycling accidents is also increasing steadily due to the lack of safety awareness and regulations. Focusing on this issue, we propose and develop a smart LED bicycle helmet in order to reduce a risk of cycling accident. The main idea is to change status of the LED on the helmet based on the bicycle's movement and provide motion information of the bicycle for others. To control the LED lights on the helmet, we use the Arduino board which communicates with the LED module through serial connection. We decide motion information by using the values from acceleration and GPS sensors of the smartphone. To receive this information from the smartphone, the control board and the smartphone are connected by Bluetooth.

The prospect of live vaccines consisting of genetically modified vaccinia virus expressing foreign genes is exciting, but important issues concerning safety and efficacy need to resolved. Vaccinia virus (VV) is an efficient expression vector with broad host range infectivity and large DNA capacity. This vector has been particularly useful for identifying target antigens for humoral and cell-mediated immunity. The WHO smallpox eradication program, involving the extensive use of VV vaccines, resulted in the late 1970s in the elimination of one of the world's most feared diseases. This achievement is a triumph for preventive medicine and for international collaboration in public health. In 1980, WHO recommended that the routine use of smallpox vaccine should be stopped. Against this background, the prospect of li ve vaccines consisting of genetically modified VV expressing foreign antigens arising from the work of Moss, and Paoletti and their colleagues in 1982 has been greeted with enthusiasm. These investigators have shown that genes coding for immunogenic proteins can be inserted into VV DNA without impairing the ability of the virus to grow in cell culture. Moreover experimental animals infected with VV recombinants containing genes coding for a variety of immunizing proteins have been shown to be protected against challenge infection with the corresponding infectious agent. In this communication, I describe current progress in the construction of a novel plasmid vector that facilitate the insertion and expression of foreign genes in VV as well as the selection of recombinants.

This study is performed for the investigation of management of personnel, wages, welfare, communication, labor, safety, treatment improvement according to assigned working places(primary, middle and high school). This study is based on the final analysis summarized on the 285 questionnaire answered by employee for school foodservice in Buchon city after distributing total 500 questionnaire. The conclusion of this analysis of study is as following. This report says the reason of this mind is caused by hard work. This investigation says they feel to be compensated with low wages on the contrary their hard working and this caused them to demoralize and increase to give up their jobs. The long tenn vacation like childcare vacation is newly established by present improvement of working condition but this improvement action is ineffective. Many of them are feeling to a fatigue and ill health and the condition of occupational disease as hard work. The present improvement of irregular employee treatment like above cases is not effective. So the rewards and payment shall be considered according to their hard work and the working condition must be improved practically for the settlement of their job without leaving.

Due to the rapidly ageing population and low birth rates, most countries have faced with the problems of an ageing population. As a result, research into aging and the means to support an aging population has therefore become a priority for many governments around the world. Ambient Assisted Living(AAL) approach is the way to guarantee better life conditions for the aged and for monitoring their health conditions by the development of innovative technologies and services. AAL technologies can provide more safety for the elderly, offering emergency response mechanisms and fall detection solutions. Since the information transmitted in AAL systems is very personal, however, the security and privacy of such data are becoming important issues that must be dealt with. In this paper, we propose a Chameleon hash-based secure authentication protocol for AAL systems. The proposed authentication protocol not only supports several important security requirements needed by the AAL systems, but can also withstand various types of attacks. In addition, the security analysis results show that the proposed authentication protocol is more efficient and secure than the existing authentication protocols.

The importance of livestock production of agriculture in Korea is very large. Investments in sanitation facilities and environmental factors such as animal health and odor have been relatively crude, and over the past few years animal disease has emerged as the leading cause of domestic livestock farmers' income stability. There is a need for an access control system that can be purchased and installed by small and medium-sized farmers who are suffering from pollutants and small farmers who can not afford to install costly sterilization on an economical basis. In this paper, based on the plasma access control system proposed previously, we developed an ICT surveillance access control prototype system that can ensure safety and security through access control and integrated control system that introduces a sterilization system using plasma required by farmers affected by pollutants.

Various attempts have been made to prevent crime risk. One of the cases where outdoor pedestrians are attacked by criminals is the abnormal health condition. When a mental or mental condition that can not sustain normal walking due to drunkenness is exposed, the case of being a crime is revealed through crime case analysis. In this study, we propose a method for estimating the state of an individual that can be detected in outdoor activities. In order to avoid the inconvenience of installing a separate terminal for event information transmission of sensors and sensors, it is possible to estimate an abnormal state by using a 3-axis acceleration sensor built in a smart phone. The state of the user can be estimated by analyzing the momentum of the user and analyzing it with the passage of time. It is possible to distinguish the flow of time at regular intervals, to recognize the activity patterns in each time band, and to distinguish between normal and abnormal. In this study, we have evaluated the total amount of kinetic energy and kinetic energy in each direction of the acceleration sensor and the Fourier transformed value of the total energy amount to distinguish the abnormal state.

Head-lice infestation, pediculosis capitis, remains a public-health burden in many countries. The widely used first-line pediculicides and alternative treatments are often too costly for use in poor socio-economic settings. Ivermectin has been considered an alternate treatment for field practice. This study was composed of 2 parts, a cross-sectional survey and an intervention study. The main objectives were to determine the prevalence and potential factors associated with head-lice infestation, and to evaluate the effectiveness and safety of oral ivermectin administration. A community-based cross-sectional survey was conducted among 890 villagers in rural areas along Thai-Myanmar border. Females with infestations were eligible for the intervention study, and 181 participated in the intervention study. A post-treatment survey was conducted to assess acceptance of ivermectin as a treatment choice. Data analysis used descriptive statistics and a generalized-estimation-equation model adjusted for cluster effect. The study revealed the prevalence of head-lice infestation was 50% among females and only 3% among males. Age stratification showed a high prevalence among females aged <20 years, and among 50% of female school-children. The prevalence was persistent among those with a history of infestation. The major risk factors were residing in a setting with other infected cases, and sharing a hair comb. The study also confirmed that ivermectin was safe and effective for field-based practice. It was considered a preferable treatment option. In conclusion, behavior-change communication should be implemented to reduce the observed high prevalence of head-lice infestation. Ivermectin may be an alternative choice for head-lice treatment, especially in remote areas.
