Purpose: In Korea, the number of migrant workers is increasing. However, migrant workers have low job satisfaction due to poor working environment, and insufficient social support. This study aimed to investigate the role of social support for job satisfaction of migrant workers. Method: We have analyzed the survey data of 397 migrant workers collected from free clinic for migrant workers located in Seoul, Gyeonggi-do and Chungcheong-do. Result: When the migrant workers received monetary and emotional supports from supervisors and colleagues, their job satisfaction turned out to be significantly high. The factors that influence job satisfaction of migrant workers are as follows: involvement in manufacturing industry, over 9 hours of daily sleep, monetary and emotional support from supervisors.

As many applications are possible now in mobile environment with the trend of mobile convergence, diverse applications in healthcare industry are also possible in mobile devices. Though lots of researches on mobile and health services are introduced, they are limited to specific area or techniques. This study shows possible directions of fusion between mobile technologies and health services in the future using a data mining technique called association rule analysis. The data used in this study is collected from web pages containing key words related to mobile technologies and health services. The analysis shows that current cases of fusion between monitoring based telemedicine and patients. It also shows another case of fusion between mobile hospital and medical screen charts. These show that fusion between mobile technologies and health services already began in industry. Association rules are found between well-being, city, diet, and sleep. The association rules containing security and privacy, though their associations are not so strong, also show that security and privacy of patient information should be protected in the future. The results show that the fusion of mobile technologies and health services is expected to provide health services to more users and larger areas. It is also expected to create new diverse business models in the future.

In this paper, automatic recognition of an accident and whether service delivery and risk driving through the giving of the driver to correct driving habits before and after the accident to reproduce highly scalable video Smart Mobile Blackbox DVR (SMBD, Smart Mobile Blackbox DVR) Computer of the model was designed. SMBD on embedded systems equipped with wireless capabilities to sleep in the car accident point and the image information by wireless communications, by notification in the control center, 24-hour emergency rescue service and traffic information can be provided. The vehicle ECU (Electronic Control Unit) of the vehicle information and sensor data in conjunction with wireless eCall (Emergency Call) services can be realized.

The purpose of this study is to investigate children's emotional problems (attention problem, aggression, somatic symptom, social withdrawal, depression) and to examine the relationship between children's emotional problems with family characteristics (parent education, parent job, family income), life-styles (gaming times, TV times, sleep time). The sample was 2,140 collections of second grade children and their parents who participated in Korea Youth Panel Survey on 2011. We analyzed the data which were collected by means of questionnaires and the data were analyzed with t -test, ANOVA, Pearson correlation analysis, and regression analysis with SPSS ver. 19.0. The results were summarized as follows. The level of children's emotional problem was relatively low on average. There is a significant difference in the children's emotional problems according to family characteristics and life-styles. There was a relationship between children's emotional problems (attention problem, aggression, somatic symptom, social withdrawal, depression) and life-styles (gaming times, TV times). The significant factors influencing the children's emotional problems are connected with father's education, mother's job, family income, family characteristics, gaming time and TV time of life style. It is noted that parent education level was an important factor for children's attention problem and aggression. Amongst children's life-styles, gaming time and TV time are negative factors for social withdrawal and depression.

무선 센서 네트워크에서는 에너지가 제한된 배터리로 네트워크를 구성하기 때문에 에너지 효율적 사용에 대한 연구가 주요한 이슈이다. 본 논문에서는 효율적인 에너지 사용을 위하여 트래픽 변화 환경을 위한 Wakeup 주기 제어 메커니즘을 제안한다. 제안되는 MAC 프로토콜은 수신자의 제어 신호로 데이터 전송이 시작된다. 송신 노드는 트래픽이 변화를 데이터 패킷 프레임에 플래그(flag)를 추가하여 수신노드에 전달한다. 수신 노드는 이를 통해 수신 노드의 Wakeup 주기를 제어한다. 제안되는 MAC 프로토콜은 트래픽이 적을 경우 수신 노드의 sleep 구간의 증가를 통하여 에너지가 절약된다. 또한 트래픽이 높은 경우 수신 노드의 Wakeup 주기를 줄여 송신 노드의 idle listening으로 발생하는 에너지 소모를 감소시킨다. 제안되는 MAC 프로토콜은 기존의 프로토콜과 비교하여 빠르게 Wakeup 주기를 조절함으로서 에너지 효율적면에서 더 좋은 성능을 보여준다.

Purpose: The purpose of this research was to examine the degree of care stress and the quality of life of grandmothers caring for their grandchildren while mother was employed. Method: A convenience sample of 107 grandmothers were measured for grandmother's care stress using a revised for of the PSI/SF and the quality of life tool by Andrew and Weinert. Descriptive statistics, t-test, and Pearson correlation coeffcients were used to analyze the data using SPSS/PC 10.0 Results: The results found that grandmothers' care stress was high according to their age and religion. Their quality of life was low according to their age, their present health status, income and sleep pattern. Their subjective care stress was a sense of social isolation, burden of caring for grandchildren, health problems, and conflict with adult children. Care stress and quality of life were found to be negatively correlated. This result was statistically significant. Conclusion: In conclusion, it was found that the care stress was high and affected quality of life. From this study it is proposed that there is a need to develop programs which consider grandmother' techniques in child care and health care to improve their quality of life. Ultimately, a good care environment for children will be good for the children's growth and development.

Ventilation requirement of apartment was mandated according to building equipment standards in 2006. When ventilation unit was considering for indoor air quality maintenance, we needed energy saving and efficiency ventilation control methods. This study carried out experiment of ventilation rate 0.7 adequacy. When we lived in apartment, we assumed that sleeping time was long stayed time in unconsciousness. Experiments carried out ventilation rate 0, 0.1, 0.4 and 0.7 in environment chamber from 22 o'clock to 06 o'clock, the concentration of $CO_2$, temperature and humidity rate measured. Analyzing the results, conclusions are as follows. 1) When we sleep in bedroom, ventilation rate 0.4 meet the requirements of domestic legal standards. Conform fan of similarity law, ventilation rate 0.4 reduced power cost about 80% than 0.7. 2) In generally sleeping time 8 hours, peak point control reduced running time of ventilation unit about 43% than normal control.
