This research focused on the consciousness and behavior of married-teachers to support their aged-parents. The subject of this study was 239 married-teachers, in the Gyeongnam area, Korea, living with at least one of their old-parents. Statistical analysis was carried out using SPSS/WIN programs including frequencies, t-test, one-way ANOVA, correlation analysis and stepwise regression. The major findings in this study are as follows; 1) Degree of consciousness in supporting married-teachers' aged parents was 3.98 on a scale of 0-5.0. The significant variables affecting the results were sex, living-distance, and familism. 2) Degree of behavior in supporting married-teachers' aged parents was 3.07 on a scale of 0-4.0. The significant variables affecting the results were number of child, living-distance, economic level of aged parents, and self-esteem. 3) There was a close relationship between the consciousness and behavior of married-teachers to support their aged-parents. 4) Stepwise regression analysis showed that the most effective variable of the married-teachers' behavior for supporting aged-parents was supporting consciousness.

As many countries have been raising awareness of environmental issues, greater efforts for eco-friendly construction have been made in both governmental and private sectors. However, assessment circumstances for building energy performance and green building standard of legislation are still based on two dimension and handwork. This takes time, cost and labor, and makes assessment inaccurate and inefficient. Therefore, this study suggests methods to improve eco-friendly construction permission process and to automatize open BIM-based assessment of Energy Performance Index (EPI) among several eco-friendly construction certification standards. First, it analyzes the relations between assessment criteria and IFC data, and provides solutions to problems and limitations. Second, it applies the solutions to assessment program in order to automatize open BIM-based assessment for EPI. The eco-friendly construction permission process with these solutions applied will reduce time, cost, and labor by simplifying and automatizing the tasks. Also, the simplified process of design revision will improve not only productivity and efficiency but also accuracy and reliability.
The types of errors corrected by a Korean spelling and grammar checker can be classified into isolated-term spelling errors and context-sensitive spelling errors (CSSE). CSSEs are difficult to detect and to correct, since they are correct words when examined alone. Thus, they can be corrected only by considering the semantic and syntactic relations to their context. CSSEs, which are frequently made even by expert wiriters, significantly affect the reliability of spelling and grammar checkers. An existing Korean spelling and grammar checker developed by P University (KSGC 4.5) adopts hand-made correction rules for correcting CSSEs. The KSGC 4.5 is designed to obtain very high precision, which results in an extremely low recall. Our overall goal of previous works was to improve the recall without considerably lowering the precision, by generalizing CSSE correction rules that mainly depend on linguistic knowledge. A variety of rule-based methods has been proposed in previous works, and the best performance showed 95.19% of average precision and 37.56% of recall. This study thus proposes a statistics based method using a conditional probability model with dynamic window sizes. in order to further improve the recall. The proposed method obtained 97.23% of average precision and 50.50% of recall.
The purpose of this study is to predict the economic size of foods-for-elderly market, which will be valuable information for establishing related policy and backup system. After setting the scope of related industry, detailed information for current market situation was investigated and a systematic forecast for market changes in the future was performed. Economic growth, changes in consumer expenditure and economic status of the elderly, current subscription of medical insurance and saving for pension were reflected. In addition, a survey toward related firms was completed and changes in aged population and incidence of chronic disease in the elderly were taken into account. Results show that the annual growth rate of the market was predicted to be the minimum 4.54% through the maximum 8.32% from 2010 to 2025 and its market size was forecasted to be the minimum 7,073 ten million won through the maximum 10,976 ten million won. It is expected that the market of foods-for-elderly will grow rapidly with development of foods technology and fast increase of aged population. Especially, growth of health functional foods and foods for special dietary uses for elderly will be distinguished. However, it seems that related firms are on the hedge, watching current trend of the related industry. This may results in insufficient supply against the demand. Therefore, policy for foods-for-elderly should be introduced and systematically administered, including R&D support, standardization and authentication for foods-for-elderly, construction of related database system.

Beginning with retirement in 2010 of the leading group of baby boomer generation born in 1955, baby boomers are starting to retire from work in full-scale. Since retirement of baby boomers refers to increase in the senior class with longer life expectancies caused by development of medical technologies, enhancement of living standards, and improvement of surrounding environments, annually decreasing birthrate is further accelerating entry of our society into an aged society. Accordingly to examine baby boomer generation's preparation for retirement in relation to career self-efficacy, first, difference in retirement preparation according to mean monthly income and current occupation was analyzed. Second, the effect of career self-efficacy on retirement preparation was studied. The survey for this study was conducted for one month between January 17 and February 16, 2012 in Seoul, Gyeonggi, Gangwon, Chungnam, Gyeongnam, Jeonnam, and Jeju. 500 surveys were distributed to baby boomer generations through direct visit and mail, among which 443 responses were returned. 400 effective responses were selected as subjects of the study. As a result, preparation for retirement according to mean monthly income was verified to be significant in terms of economic and physical factors. Significant results were shown in all factors including economic, physical and social factors for retirement preparation according to current occupation. Career self-efficacy had greatest influence of 58% on retirement preparation with economic factors. It also influenced all factors including self assessment, objective setting, occupational information, and problem solving.

By defining a travel disparity based on the degree to which travelers diversify their destinations, this paper examines how socioeconomic and spatial factors affect the travel disparity among the elderly in Seoul. This paper uses the COVID-19 pandemic as a natural experiment which can bring about different behavioral responses among the older travelers. Using the smart card data, we compare the destination diversification patterns before and after the pandemic. In the early morning(4:30-9:00), the degree of destination diversification varies between the core and the periphery and this trend persists through the pandemic. In the late morning(9:00-12:00), a new trend of disparity appeared after the pandemic. Although those who hold higher socioeconomic status and live closer to the core have a larger range of choices for destinations, the difference of range did not lead to differences in diversification before the pandemic, due to the discretionary nature of the elderly's trip. In contrast, as the elderly were forced to search alternative destinations right after the outbreak of the pandemic, the range of choices became an important factor causing observable differences in destination diversification. The findings suggest that the travel disparity observed during the pandemic is due to the difference in the range of choices by socioeconomic and spatial factors.
Edible insects are reported to be rich in protein, minerals and vitamins, and much attention has been paid to them as a future food source. In Korea, they were massively reared and sold. In order to enhance the market value of edible insects for industrialized mass production, it is important to develop the safe and nutritious feed sources for rearing them are needed. In this study, a chlorella-free control feed (Exp1) and six experimental feeds supplemented with 0.5~2.0% liquid or powder types of chlorella were formulated. Protaetia brevitarsis and Allomyrina dichotoma, registered as food ingredients in Korea, were fed with the designed feeds and parameters of growth including larval survivorship, larval body weight, and larval period were analyzed. When chlorella added, larval survivorship was increased 2~13%(p>0.05) and 9~22%(p<0.05) in each beetle compared to the control. Interestingly, the larval period of chlorella powder-added groups was shortened by 24 days (Exp3, p<0.05) in P. brevitarsis and 19 days (Exp4, p<0.01) in A. dichotoma. Meanwhile, some parameters, crude protein, crude fiber, copper, zinc, potassium, magnesium, and phosphorous, in chlorella-added groups of P. brevitarsis were also higher than the control group. Therefore, chlorella could promote the larval growth performance of these two beetles and be used as a feed additive in rearing them.

Domestic agriculture is facing real problems, such as a decrease in the population in rural areas, a shortage of labor due to an aging population, and increased risks due to the deepening of climate change. Smart farming technology is being developed to solve these problems. In the development of smart agricultural technology, irrigation control plays an important role in creating an optimal growth environment and is an important issue in terms of environmental protection. This paper is about the study of collecting and analyzing the rhizosphere environmental data of domestic paprika farms for the purpose of improving the quality of crops, reducing production costs, and increasing production. Irrigation control modeling presented in this paper Control modeling is to graphically present changes in a medium weight, feed, and drainage due to regional climatic features. To derive the graph, the parameters were determined through data collection and analysis, and the suggested irrigation control modeling method was applied to the collected rhizosphere environmental data to control irrigation in 6 regions (Gangwon-do, Chungnam, Jeonbuk, Jeonnam, Gyeongbuk, and Gyeongnam). The parameters were obtained and graphs were derived from them. After that, a study was conducted to analyze the derived parameters to verify the validity of the irrigation control modeling method and to correlate them with climatic features (average temperature and precipitation).
Purposes: The convenience of smartphones have lead to people's overdependence on devices, which may cause obstacles in daily life. It is useful to manage smartphone overdependence by using mobile health applications. We aimed to investigate the acceptance of mobile health applications designed to help in the management of smartphone overdependence. Methodology/Approach: We developed the extended model based on the Unified Theory of Acceptance and Use of Technology 2. The modified model had six hypotheses with six variables: result demonstrability, performance expectancy, effort expectancy, social influence, perceived risk, and behavioral intention to use. We randomly included 425 smartphone users in an online survey in 2020. A structural equation model was used to estimate the significance of the path coefficients. Findings: Performance expectancy and social influence had a very strong direct positive association with behavioral intention to use. Result demonstrability had a direct positive association with performance expectancy. Perceived risk had a strong direct negative association with performance expectancy. Performance expectancy and social influence were the main factors directly influencing the acceptance of mobile health applications for the management of smartphone overdependence. Practical Implications: We demonstrated smartphone users' acceptance of mobile health applications for smartphone overdependence management. Based on these results, we could develop mobile health applications more effectively.

1950-meter-tall goddess is Seolmundae Grandmother with the head of the 1950m Hallasan Mountain Baengnokdam and the body of the mountain ridgeline. Seolmundae Grandmother in Jeju is a folk belief that has been passed down from generation to generation in Jeju. Unlike inland, Seolmundae Grandmother, which had femininity in the customs of Jeju, which was a matrilineal society, developed into an absolute faith in Jeju, metaphorizing that in some way it was inevitable. Seolmundae Grandmother was the only subject that could mentally solve the biggest problem for Jeju residents, even if they were disconnected from the mainland. In other words, Seolmundae Grandmother was unable to make underwear for Seolmundae Grandmother because it was short of 100 bottles of silk, the god of Hallasan, a huge being and a physical symbol. Therefore, Semyungju Grandmother gave up the bridge connecting the mainland and Jeju. In this paper, focusing on the fact that Mt. Halla, covered with snow in winter, is like a skein of silk thread that we usually use in our daily lives, the etymology of Seolmundae has been changed to Saengmyeongju, - Semyungju, which is a skein of fine silk. As a basis for this, there is a custom of tying a thread of silk in 'Semyungju', a shrine to Semyeongju in Halmangdang, 'Hanmosal' along the coast of Pyoseon-myeon. The silk thread is the core of the Packing DNA gene. The summit of Mt. Halla, Ninety-Nine Valleys, and five hundred generals, found in Seolmundae Grandmother or White Silk, expressed the symbols of Jeju. The Packing DNA gene was found to originate in the Jeongnang
