Summed area table allows filtering of arbitrary-width box regions for every pixel in constant time per pixel. This characteristic makes it beneficial in image processing applications where the sum or average of the surrounding pixel intensity is required. Although calculating the summed area table of an image data is primarily a memory bound job consisting of row or column-wise summation, previous works had to endure excessive access to the high latency global memory in order to exploit data parallelism. In this paper, we propose an efficient algorithm for generating the summed area table in the GPGPU environment where the input is decomposed into square sub-images with intermediate data that are propagated between them. By doing so, the global memory access is almost halved compared to the previous methods making an efficient use of the available memory bandwidth. The results show a substantial increase in performance.

Purpose: Regular cancer screening for workers can help prevent cancer or allow early treatment, and is thus beneficial in improving health, reducing costs, and increasing companies' productivity. However, there has been little research on cancer screening rates of workers and related factors. The purpose of this study was to identify cancer screening rates and relevant factors among manufacturing workers. Methods: Using a questionnaire, data were collected from 335 workers aged over 40 years recruited from seven manufacturing companies. The collected information included cancer screenings (stomach, colorectal, breast, and cervical), attitude towards cancer screening, and demographic and job characteristics. Results: 72.5% of workers received stomach cancer screening (SCS), and 43% received colorectal cancer screening (CRCS). Among 86 women, 68.6% received breast cancer screening and cervical cancer screening. The attitude towards cancer screening was $29.5{\pm}3.78$. Workers aged over 51, married, and those working in mobile manufacturing were more likely to have undergone SCS. Workers aged over 51, married, those working in mobile manufacturing, those in workplaces with more than 1,001 employees, and those with more positive attitudes toward cancer screening were more likely to have undergone CRCS. Finally, attitude affected cervical cancer screening. Conclusion: Workers in small-sized workplaces had lower cancer screening rates. Thus, follow-up research should assess the health environment of workplaces and develop educational programs on cancer screening that reflect attitudes towards screening.

This study was conducted in order to investigate the factors affecting the elderly employment and especially focused on the factor of their residential areas. This paper performs binary logistic regression analysis with the micro data of 2014 Survey of Living Conditions and Welfare Needs of Older Koreans. To reveal the influence on the elderly employment, various dependent variables was used such as demographical, health, household, economic, lifelong job, living environment, and residential area characteristics. The elderly in rural areas have higher possibility of currently working than those in urban areas. Based on the results, more various and complex factors affected on the employment of the urban elderly. This suggested that differentiated policy supports were needed in the urban and rural areas.

Business organizations need to introduce trans-oriented response way and efficient management skill to survive in these days of severe struggle for existence. The new management models now ask organizations for building a new employee-employer relationship. As the economic recession continues and consumption shrinks around the world, many companies are in trouble. Companies will fall behind in the market unless they respond to this seamless and fast-changing business environment and market in a structured fashion. Therefore, the importance of leadership is growing bigger and bigger. This study reviewed prior literatures dealing with the servant leadership and surveyed workers in the service industry. Resultingly, it was found that servant leadership had positive effects on organizational commitment and organizational citizenship behavior, and that the superior's trust affected the effect of servant leadership on organizational commitment.

High incident of accidents in construction jobsite became a social problem. According to the International Labour Organization (ILO), more than 60,000 fatal accidents occur each year in construction workplace worldwide. This number of accidents accounts for about 17 percent of all fatal workplace accidents. Especially, accidents from struck-by and falls comprise of over 60 percent of construction fatalities. This paper introduces a prototype of a received signal strength index (RSSI)-based safety monitoring to mitigate the potential accidents caused by falls and struck-by. Correlation between signal strength and noise index is examined to create the distance profile between a transmitter and a receiver. Throughout the distributed sensor nodes attached on potential hazardous objects, the proposed prototype envisions that construction workers with a tracker-tag can identify and monitor their current working environment in construction workplace, and early warning system can reduce the incidents of fatal accident in construction job site.

In recent days North Korean refugees. who hope to move into and settle in South Korea, have been rapidly increasing. However their adaptation to South Korea is reported to have not been so much successful as they expected. Considering such situations, this study attempts to investigate their information needs and behavior. North Korean refugees have various and strong information needs for settlement and daily life. The strongest were information needs related to economic Problem, specifically job and business related information needs. It was followed by information needs related to social welfare, health and security child care and education, and North Korean situation In order to meet their information needs. North Korean refugees were heavily dependent on informal interpersonal information sources such as their family members. friends. and their own neighborhoods. as compared to such formal interpersonal information sources as Public officers. social welfare agents, and NGOs members. Meanwhile. their usage of mass media such as TV. newspapers, and internet as information sources was also heavy However the overall information environment surrounding them appeared to be relatively inferior to that of average South Koreans.

Current risk assessment practices largely reflect the need for a consistent set of relatively rapid, first-cut procedures to assess 'plausible upper limits' of various risks. These practices have important roles to play in 1) screening candidate hazards for initial attention and 2) directing attention to cases where moderate-cost measures to control exposures are likely to be warranted, in the absence of further extensive (and expensive) data gathering and analysis. A problem with the current practices, however, is that they have led assessors to do a generally poor job of analyzing and expressing uncertainties, fostering 'One-Number Disease' (in which everything from one's social policy position on risk acceptance to one's technical judgment on the likelihood of different cancer dose-response relationships is rolled into a single quantity). At least for analyses that involve relatively important decisions for society (both relatively large potential health risks and relatively large potential economic costs or other disruptions), we can and should at least go one further step - and that is to assess and convey both a central tendency estimate of exposure and risk as well as our more conventional 'conservative' upper-confidence-limit values. To accomplish this, more sophisticated efforts are needed to appropriately represent the likely effects of various sources of uncertainty along the casual chain from the release of toxicants to the production of adverse effects. When the effects of individual sources of uncertainty are assessed (and any important interactions included), Monte Carlo simulation procedures can be used to produce an overall analysis of uncertainties and to highlight areas where uncertainties might be appreciably reduced by further study. Beyond the information yielded by such analyses for decision-making in a few important cases, the value of doing several exemplary risk assessments in. this way is that a set of benchmarks can be defined that will help calibrate the assumptions used in the larger number of risk assessments that must be done by 'default' procedures.

Objectives : Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Methods : Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Results : Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Conclusions : Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.

The industrial health education is the most fundamental and active area in the industrial health. It has become increasingly recognized as an important component of preventive occupational health programs and is an essential service for improvement of productivity and employee's health. Evaluating the worker's health status is a part of the occupational health promotion policy and is very important to know the efficiency of the occupational health service. In this point, the purpose of this study was to clarify the effect of the industrial health education on worker's health status. This study included a survey of 625 workers at 28 factories in Puchon area form August Z7 to September 30, 1996. The research was carried out through the analysis of the self-administered questionnaires and health examination records. The results were as follows: 1. For demographic characteristics, 66.5% of the respondents were male. The most prevalent age group was 30 - 39years group(30.4%). Those who graduated from high school were 43.5%. The workers whose monthly income ranged from 600,000 to 100,000 won were 40.3%. As for the marital status, 69.4% of the respondents were married. 2.

Object of this study presents marketing of new market segmentation as what I classify a social stratum, and analyze sense of value about each social class clothes and a taste, but is. The study way used a questionnaire as an investigation study way, and I did execution from September to October in 1999, and the investigation object picked up an any table with the woman university student who lived in Seoul and did investigation, and analysis targeted total 550 people. I used a measurement item of economic capital and cultural capital as a classification item of a social stratum and selected a dwelling, a kind of property, an annual salary of parents as an index of economic capital. Presentation held an occupation of parents, scholarship, culture activity as an index of cultural capital. It is social stratum structure an occupation arranges in 12 job categories by, for your reference, I do a social orbit of the P. Bourdieu which is a French sociologist and an index of inheritance cultural capital, and having set up eight phases of evaluation, and to do a Y, Cultural Capital with X with economic capital. Sense of value about clothes and attitude selected social value, aesthetic appreciation enemy value, authority a few value in sense of value of the 6 type that E. Spranger(1922) presented, and a proposal did type in 3 about clothes. The measurement way used a 11 question item and measured I with five phases of Likert-type criteria and executed factors analysis by main ingredient analysis and varimax revolution law. I named a more than inherent 1 with the liver which was social man, aesthetic appreciation enemy man, an authority enemy with a basis. The results are as follows : People of the group which they belong to the same social class, and there is have a similar taste and select a similar product, and scholarship and an occupation of parents please lay a taste of children and sense of value, a hierarchical difference of attitude too and do it.
