  • Frequent outbreaks of foodborne illness have been increasing the awareness of food safety. Conventional methods for pathogen detection and identification are labor-intensive and take days to complete. Some immunological, rapid assays are developed, but these assays still require prolonged enrichment steps. Recently developed biosensors have shown potential for the rapid detection of foodborne pathogens. In this study, an impedimetric biosensor was developed for rapid detection of Salmonella entritidis in food sample. To develop the biosensor, an interdigitated microelectrode (IME) was fabricated by using a semiconductor fabrication process. Anti-Salmonella antibodies were immobilized based on neutravidin-biotin binding on the surface of the IME to form an active sensing layer. To evaluate the effect of electrode gap on sensitivity of the sensor, 3 types of sensors with different electrode gap sizes (2, 5, and $10{\mu}m$) were fabricated and tested. The impedimetric biosensor could detect $10^3\;CFU/mL$ of Salmonella in pork meat extract with an incubation time of 5 min. This method may provide a simple, rapid, and sensitive method to detect foodborne pathogens.

  • This study aims to investigate factors that affect elderly poverty based on a comprehensive and universal perspective, suggesting some alternatives for improving the poverty rate of the elderly. The comprehensive and universal approach to the poverty of the aged that this study attempts can give a better understanding of the elderly poverty beyond the contribution of the existing literature, with the research model including individual, family, labor, and income factors as the causes of old-age poverty from the comprehensive and universal perspective on the causes of poverty of the elderly. In addition, the study attempts to input variants of variables into the equation for the causes of elderly poverty by using panel data from the 8th Korean Retirement and Income Study. This study employs decision tree analysis to determine the cause of the poverty of the elderly using CHAID. The decision tree analysis shows that the most vital variable affecting elderly poverty is making income. For the poor elderly without earned income, public pensions, educational careers, and residential areas influence elderly poverty, but for the poor elderly with earned income, wage earners and gender are variables that affect poverty. This study suggests some alternatives to improve the poverty rate of the aged. The government should create a better working environment such as senior re-employment for old people to be able to participate in economic activities, improve public pension or social security for workers with unfavorable conditions for public security of old age, and give companies that create employment of the aged diverse incentives.

  • The rural living improvement in Japan operates in considerations of socio-eoonomic circumstances of rural community as in Korea. After 1945 the program emphasized the improvement of living conditions such as poverty alienation improvement of house and toilet nutrition after war, From 1955, health programs including better cooking and nutrition, house modification and improved living conditions corresponding to the goal of the developed country were carried out. In 1965. the goal of the rural home economics was focused on the harmonized production and living, improvement of the levels of rural living, health and building rural community. From 1975, the goals of the program were to organize the farming in the better ways and improvement of rural women's role. In 1985, making agreeable living conditions was emphasized under the goal of vital rural society. From the period of Heysey(1989${\sim}$), for better living of rural people the government is emphasizing the programs including farm labor management, utilization of farm products, farm management and rural environments. Recognizing the important influencing resources of agents in extension services, on the job and education was implemented step by step from basic to planning to upgrade competencies. The government is trying to construct better with infrastructures, encouraging direct selling the value-added processed food from local farm products with rural people's real name and other countryside resources. Major programs in the 21st centuries are building better rural society with men and women together and considering elders as well as new farmers.

  • People are often motivated by money. The salary a worker is paid by his employer can have a great influence on his performance in the administration. The study aims to identify and measure the impact of collective bargaining on the income of employees in enterprises. Participants were given a questionnaire consisting of 21 observation variables with a 5-point Likert scale. Independent variables were measured from 1 "without effect" to 5 "strongly". Based on the literature review and results of interviews, a total of 285 questionnaires were sent to participants in 95 enterprises in three typical fields: industry, construction, textile, and garment; 255 of them met the standards and were subject to be analyzed. We use qualitative research methods combined with quantitative research methods. SPSS20 software is used to synthesize and analyze data. The results of Cronbach's alpha, Exploratory Factor Analysis (EFA) and Multiple Regression Analysis (MRA) identify, the objective for collective bargaining (MT), time to organize collective bargaining (TD), the competence of the parties of the collective bargaining (NL), collective bargaining organization process (QT) are positively correlated with the income of workers in enterprises; information provided for collective bargaining (TT) has a negative correlation with the income of employees in enterprises. Based on the findings, some suggestions have been given for collective bargaining to increase the income of employees in enterprises in Vietnam.

  • One of the most pressing socioeconomic problems confronting humanity on a worldwide scale is food security, particularly in light of the expanding population and declining land productivity. These causes have increased the number of people in the world who are at risk of starving and have caused the natural ecosystems to degrade at previously unheard-of speeds. Happily, the Internet of Things (IoT) development provides a glimmer of light for those worried about food security through smart agriculture-a development that is particularly relevant to automating food production operations in order to reduce labor expenses. When compared to conventional farming techniques, smart agriculture has the benefit of maximizing resource use through precise chemical input application and regulation of environmental factors like temperature and humidity. Farmers may make data-driven choices about the possibility of insect invasion, natural disasters, anticipated yields, and even prospective market shifts with the use of smart farming tools. The technical foundation of smart agriculture serves as a potential response to worries about food security. It is made up of wireless sensor networks and integrated cloud computing modules inside IoT.

  • The increased number of organized employees and amount of collective bargaining in the public sector has caused many industrial relations students to pay attention to the compulsory arbitration mechanism. Some of these have criticized the compulsory arbitration on the grounds that it tends to replace collective bargain ing itself. They argue that each party lacks the incentive to concede and compromise that is so necessary in reaching agreements as long as the threat and/or use of strike is unavailable to them. On the other hand, the proponents of the compulsory arbitration maintain that compulsory arbitration carries out a strike like function by imposing the cost of disagreement. This paper is primarily concerned with these contradictory issues. More particularly, an attempt is made to analyze the impact of the compulsory arbitration mechanism upon the collective bargaining process by developing a bargaining model with explicit considerations of the determinants of the concession behavior of each party as a function of the cost of disagreement and the risk willingness relationship between the parties. The analysis in this paper leads to a synthesis of the above competing arguments, and shows that those contradictory views on the effect of the compulsory arbitration are mainly due to their failure to con sider the concession process.

  • The paper examines the effects of Foreign Direct Investment (FDI) on the economic growth of Lao People's Democratic Republic (Lao PDR) between 1993 and 2015. The investigation is based on the influence of growth and economic absorptive capability determinants such as human capital, trade openness, and institutional quality. The methodological analysis uses a multivariate framework accounting capital stock, labor stock, FDI, human capital, trade openness, and institutional quality in regression of the Vector Autoregressive model. Augmented Dickey-Fuller unit root test, Johansen Cointegration test, and Granger Causality test were applied as parts of the econometric time-series analysis approach. The empirical results demonstrate the positive effects of FDI and trade openness, and the negative effects of human capital and institutional quality on the economic growth of the Lao PDR over the 1993 to 2015 period. The findings confirm that trade openness complemented by a sufficient level of infrastructure, education, quality institutions, and transparency significantly influence economic growth and attract more FDI. Research results lend credence to the need for the Lao PDR's government to focus on improving its economic absorptive capability and economic competitiveness regionally and globally by improving wealth and resource management strategies, as failure to take this course of action could lead to the Dutch Disease effects.

  • This study is to analyse the reimbursement prices of drugs in Japan. Japan has the world's second-largest pharmaceutical market, and the world's largest price-controlled pharmaceutical market. The reimbursement prices of new drugs in Japan are determined by confidential negotiations between the manufacturer and the Japanese Ministry of Health, Labor, and Welfare. Pharmaceuticals account for a larger share of total healthcare expenditures in Japan than in most other major pharmaceutical markets such as France, Germany, United Kingdom and United States. Prescription drugs' share of total healthcare spending has slightly increased in recent years, from 20.2% in 2000 to 21.5% in 2004, the most recent year for which data are currently available. This trend is attributable to the effect of the Japanese rapidly aging population that stimulates demand for healthcare services. There are several method of price setting for drugs as below. First, on the initial pricing of branded drugs, is the similar-efficacy pricing method and cost calculation method. Second is postmarketing price changes which are biennial price revisions under the rule of National Health Insurance. Third is the rule of the generics price. Recently, the generics market is expanded because there are increasing numbers of hospitals by DPCs(Diagnosis-procedure Combinations).

  • This is a descriptive study that introduces programs that support family caregivers looking after the elderly, by focusing on the case of Georgia, in the United States. The U.S. is one of the few countries that support family caregivers by law. In this study, we focus on the evidence-based interventions implemented through the Alzheimer's Disease Supportive Services Program (ADSSP), a federal policy that complements the National Family Caregiver Support Program (NFCSP). Our findings show that one-on-one evidence-based programs (EBPs) for family caregivers are both economical and effective in assisting caregivers. In our discussion, we highlight how the implementation of the latest EBPs can build an infrastructure to support family caregivers. ADSSP funding is useful as it constructs a caregiver support through the implementation of programs in the local community. The result is the creation of a well-coordinated division of labor among government agencies, academia and NGOs, which produces a synergetic effect in funding, research and development, translation and implementation of programs, and staff training. We conclude that the implementation of EBPs funded by the government is a useful reference for Korea and other rapidly aging countries, if we are to create an infrastructure for caregiver support, which can effectively prevent a crisis in caregiving.

  • Purpose - The purpose of this study is to clarify the mediating effect of profitability and activity in the relationship between productivity and stock return, assuming that the productivity of the company will affect share prices with the parameters of profitability and activity. Design/methodology/approach - The study extracted productivity indicators, profitability indicators, activity indicators, and share price-related indicators from 1999 to 2018 of non-financial enterprises listed on the securities market, and then classified them into three factors: productivity (labor productivity LP, capital productivity CP), activity (TT), and profitability (net profit rate NI, operating profit ratio OI) through the factor analysis method, and analyzed the impact of each factor on the stock return through steps 1 to 3. Findings - The regression analysis shows that productivity has a significant positive effect on the stock return through the full mediating effect of profitability and activity. Research implications or Originality - In a situation where the relationship between productivity and profitability is not clear, this study is meaningful in that it has empirically analyzed that productivity has a positive effect on the stock return by mediating effects of profitability and activity.
