The purpose of this study was to investigate the factors that influence elementary school learners' participation in cyber home study, and to suggest possible solutions to problem of the participation rates. To identify the factors, we analyzed the literature and developed a questionnaire consisting of 8 possible factors and 33 items. Data gathered from 429 elementary school learners were analyzed in a logistic regression model, which was utilized to determine the probability of the learner's participation in cyber home study because of any of the identified variables. We studied the following variables: problem from learning motivation & attitude, burden from computer, difficulty of new learning method, problem from instructional design, difficulty of interaction, problem from screen design, and problem from learning environment. The results indicated that two factors were important: burden from computer, difficulty of new learning method. That is to say, having a low level of burden of computer and difficulty of new learning method helps improve the rate of elementary school learners' participation in cyber home study.

In Korea, most studies have used the conventional Wolfbein and Wool method, which cannot be applied to women's work-life table because of bimodality and/or M curve of female labor force participation. The increment/decrement work-life table method, however, is equally applicable to both men and women, but requires individual data on employment transition. This paper demonstrates that the Garfinkle-Pollard method is the same as the increment/decrement work-life table method developed by Hoem, Schoen and Woodrow and adopted by BLS. The merit of Garfinkle-Pollard method is to produce work-life table using labor force participation rate without individual employment transition. This paper applies the Garfinkle-Pollard methods to the estimation and projection of work-life of Korean labor force for the period of 2000-2050, using the abridged life tables provided by Korean National Statistical Office and a projection of labor force participation rates. The work-life expectancy at 65 is 5.8 years for men and 4.1 years for women in 2000, and it increased to 7.7 years for men and 5.1 years in 2050. However, differences in work-life expectancy are found depending on the data processing of elderly labor force participation and mortality assumption. Detailed data on elderly labor force participation and further study on future mortality are required to estimate and project more accurate work-life expectancy.

Introduction: The aim of the study was to determine the breast, cervical, and colorectal cancer screening rates and the influencing factors in a group of Turkish females. Methods: This descriptive study was conducted in a School of Nursing. The study sample consisted of 603 females who were the mothers/neighbors or relatives of the nursing students. Data collection forms were developed by the investigators after the relevant literature was screened and were used to collect the data. Results: Of the women aged 30 and over, 32.8% had undergone a pap smear test at least once in their life. Of those aged 50 and over, 48.2% had undergone mammography at least once and FOBT had been performed in 12% of these women in their life. Having heard of the screening tests before, knowing why they are done, and having information on the national cancer screening program were important factors influencing the rates of women having these tests done. Discussion: The results of this study show that the rates of women participating in national cervical, breast, and colorectal cancer screening programs are not at the desired levels. Having heard of the screening tests before, knowing why they are done, and having information on the national cancer screening program were important factors influencing the rates of women having these tests done. It is suggested that written and visual campaigns to promote the service should be used to educate a larger population, thus increasing the participation rates for cancer screening programs.

Objectives: The objective of this study was to identify the differences in obesity rates among people with and without disabilities, and evaluate the relationship between obesity rates and the existence of disabilities or characteristics of disabilities. Methods: Mass screening data from 2008 from the National Disability Registry and National Health Insurance (NHI) are used. For analysis, we classified physical disability into three subtypes: upper limb disability, lower limb disability, and spinal cord injury. For a control group, we extracted people without disabilities by each subtype. To adjust for the participation rate in the NHI mass screening, we calculated and adopted the weight stratified by sex, age, and grade of disability. Differences in obesity rates between people with and without disabilities were examined by a chi-squared test. In addition, the effect of the existence of disabilities and grade of disabilities on obesity was examined by multiple logistic regression analysis. Results: People with disabilities were found to have a higher obesity rate than those without disabilities. The obesity rates were 35.2% and 35.0% (people with disabilities vs. without disabilities) in the upper limb disability, 44.5% and 34.8% in the lower limb disability, 43.4% and 34.6% in the spinal cord injury. The odds for existence of physical disability and grade of disability are higher than the nondisabilities. Conclusions: These results show that people with physical disability have a higher vulnerability to obesity.

The BESS(Battery Energy Storage System) is an useful device for load leveling, but the high cost, installation space and safety issues are the main barriers for supplying it widely. The important factor in supplying BESS to customers successfully is the payback period. As most of the H/W cost factors are uncontrollable, the optimization of storage volume can be useful factor in improving payback period. In order to obtain optimized BESS volume, the load factor, demand ratio, peak shaving ratio, electric rates and benefits from DR participation of customer should be analyzed. In this paper, we could verify the peak cutting capability and cost effectiveness under the some proposed conditions and changing value of PCS and battery based on the customers data after volume optimization process was applied, and we can identified the saturation point of load factor and shortening of customer's payback period.

Many immersion programs have been established and managed throughout Korea in recent years in schools, English villages and camps. Research on the effects of various programs has been reported with focus on the program types or the benefits and learning outcomes for the participants. The purpose of this study is to find out the effects of participation at English camp as a teaching assistant by comparing some factors such as competence, English abilities, and connection to current studies/career before and after camp experience. The results show that all 17 competence rates rose with 'crisis management' showing prominent change. Also, the camp experience provides opportunity for improving English Test scores, conversational skills, teaching skills, and mostly language confidence. Lastly, the camp helped in setting career goals and was helpful in the preparation process of job seeking. Most of the subjects, the teaching assistants at camp, replied that the impact of camp experience is useful in current studies/career. In conclusion, the experience as camp teaching assistant is valuable in many aspects.

Purpose: This case study was done to describe the health survey conducted by a community health practitioner. Methods: The community health survey was carried out from April 16 to May 31, 2018 with face to face interviews done by 48 trained senior nursing students. Results: Compared with other regions, rates for chronic disease prevalence, chewing discomfort, falls, and depression were higher than those of the relevant district/the relevant city, and the whole country. It is encouraging that the treatment rate for hypertension, diabetes, and hyperlipidemia, and walking practice rate were higher than those other regions. Those who participated in village events had low stress, and those who participated in health promotion programs had a higher quality of life. Conclusion: The community health practitioner in the public health center post needs to operate health promotion programs continuously. Programs including chronic disease management, fall prevention, depression control, and oral health management should be emphasized, and ways to increase social participation, including participation in village events should be developed.

Purpose. Korean American women have twice the rate of cervical cancer than white women and demonstrate low rates in participation in cervical cancer screening. This study was to describe the perceptions about cervical cancer and factors related to cervical cancer screening among Korean American women. Method. Focus group methods. Results. Five themes emerged. First, knowledge about cervical cancer; misconceptions about cervical cancer, its causes, reproductive anatomy and the treatment Second, perceived meanings of having cervical cancer; most of the women felt that cervical cancer represented a loss of femininity and existential value of woman-hood. Third, knowledge about cervical cancer screening; regular medical check-ups were necessary for early detection and prevention of cervical cancer. Forth, experiences and perceived meanings of cervical cancer screening; the participants expressed their feelings; embarrassment, fear, shame and shyness. Fifth, practices of cervical cancer screening; various intervals in participating in cervical cancer screening. But they mentioned several deterrents, language, insurance, time constraint, embarrassment, fear of the screening results, misbelief about susceptibility, lack of health prevention behavior, and lack of information written in Korean. Conclusion: Results emphasize the critical need for culturally appropriate health education to encourage participation of Korean American women in cervical cancer screening.

Purpose The purpose of this study is to explain the agrophotovolatic system built by the Korea South-East Power Company and to propose methods to activate the agrophotovolatic system for the development of the renewable energy industry. Design/methodology/approach We conducted a three-step simulation in order to design a photovoltaic module, and we built the agrophotovolatic system based on the results of the simulation. Then, we analyzed the monthly generation of power and the rice harvests produced on farmland using the photovoltaic module. Based on the results of the analysis, we proposed institutional improvements to increase the use of the agrophotovolatic system, and we proposed new business models to increase the participation of farmers and business persons. Findings When we compared the agrophotovolastic system with the general photovoltaic system, we found that the agrophotovoltaic system had higher utilization rates and power generation. An analysis of rice produced on farmland using the photovoltaic module showed that more than 80% of the rice produced on general farmland was harvested. We suggested activation plans that involved the revision of the farmland law and the introduction of renewable energy certificate (REC). We also proposed a land lease model and a farmer participation model as two new business models, and we conducted economic evaluations and sensitivity analyses for both models.

Duck farming restriction refers to a program in which duck farms suspend their operations for a certain period at times when the risk of avian influenza (AI) is high and receive compensation from the Korean government. This study analyzed the effect of this duck farming restriction on the incidence of AI using data on regional AI incidence rates, the program participation rate, and characteristics of poultry farming in 2016 (before the implementation of the restriction), as well as data from 2020 and 2021 (when new AI outbreaks occurred). In this study, the treatment group was divided into five subgroups according to the policy participation rate and a difference-in-difference (DID) estimation was conducted using certain covariates, in this case the average number of ducks raised, the land area, the number of high-susceptibility farms, the number of low-susceptibility farms, the average number of farms within a 3 km radius, the average distance to the nearest farm, and a year dummy. The results showed that when more than 30% of all duck farms in a region participated in the farming restriction, it had a statistically significant effect on the incidence of AI. Specifically, when more than 30, 40, 50, and 60% of all duck farms participated in the farming restriction, the AI incidence rate decreased by 0.7184, 1.0025, 1.5844, and 1.5843%p, respectively.
