Fall armyworm, Spodoptera frugiperda, is a invasive migratory pest of native to the tropical and sub-tropical regions that has recently invaded Korea with damage to cornfield. The study was conducted to investigate the development periods of S. frugiperda on artificial diet at six different temperatures. The developmental period from eggs to adult at 18, 21, 24, 27, 30 and 32℃ was 79.8, 54.2, 34.3, 28.4, 24.6 and 24.0 days, respectivery and decreased with increasing temperature. The pupal periods of females were shorter than males. Most of the larvae developed through six instar, but the ratio of 7 or more instar increased at low temperatures. The relationship between the development rate and temperature was fitted with by linear regression analysis. The lower development threshold for egg and larva development was 12.9℃ and 11.3℃, respectively, 12.6℃ for pupae and 11.8℃ for egg-to-adult development. The effective accumulative temperature for the development of the respective life cycle stages were 37.0 DD for eggs, 286.3 DD for larvae, 132.2 DD for pupae and 456.8 DD egg-to-adult development.

Currently, the world's population has already entered a super-aging era, and the rate is expected to increase rapidly to about 40% by 2050. However, the rapid development of automation technology and the online service sector, the main technologies of the Fourth Industrial Revolution, are still further isolating them in a world where many inconveniences and development technologies are applied. As such, alienation in daily life is widely expanded in various fields, but the financial service sector is one of the must-use areas regardless of age because of its strong nature in the public service sector, and is a very important factor in the period when branches are rapidly decreasing. However, the current utilization rate of mobile banking services is not around 5%, so users over 60 are rarely able to use them. The UX design of the most frequently used remittance service screen in mobile banking services was proposed, and the difficulty of trying to find the preferred bank among 56 or more banks was solved by analyzing the usage rate of each bank and dividing it into three stages by age group from 50 or older. In addition, it was designed to strengthen customized services by showing their recently used banks as the top priority. The design proposed in this study obtained an average of 4.8 points or more out of 5 points as a result of usability satisfaction through interviews with less than 50 senior groups. This study is believed to help each bank upgrade its different mobile banking designs in a unified manner.

This study explores the determinants of economic status and well-being among elderly Koreans. Particular emphasis is paid to the role of intergenerational support in these processes because institutional responses to an aging population in Korea are currently inadequate. Path model results indicate that status maintenance variables have significant effects on economic status and well-being as measured by comprehensive income. Further, inequality in comprehensive income - as measured by the Gini and Theil's indices - is substantial and increases in successive age groups. However, market-based and family-based income, two components of comprehensive income, show different patterns. Inequality in market-based income is apparently increasing, while inequality in family-based income is decreasing gradually in successive age groups. With respect to the role of intergenerational support, results indicate that family-income-focused persons possess highly vulnerable sociodemographic characteristics, and that for the socially disadvantaged elderly Koreans, intergenerational support plays a crucial role in the later stages of life. This study also discusses the implications of these findings for the transition from latency to manifestation of intergenerational support in Korea.

The purpose of this study is to explore the economic hardship experiences of low-income single-parent families by COVID-19 to find ways to improve after COVID-19. To this end, 10 single parents with children under the secondary school age were recruited through snowball sampling method and in-depth interviews with economic activities, income, expenditure, and economic life. As a result of the study, participants suffered from unemployment and the disappearance of extra income activities in the early stages of COVID-19, additional expenses incurred by children's food and increased utility bills. In addition, it was recognized that COVID-19 has come to be more difficult and unequal to single-parent families of low-income women. It was found that the temporary living difficulties were resolved with disaster support funds, and it was helpful in the short term by spending according to priorities such as overdue monthly rent, food expenses, children's academy expenses, and purchasing home appliances. However, it was recognized that disaster support funds were inappropriate for customized disaster support and long-term and selective support was necessary. In the conclusion, to improve economic problems after COVID-19, it proposed measures to improve social welfare policies and practices

In recognition of the increasing social attention paid to the notion of how to die well, this study explored what it is that middle-aged and older Koreans think of as "dying well." Specifically, it was aimed at classifying the perceptions people middle-aged and older have regarding dying well. To this end, we used data from the National Survey on Well-Dying, which was conducted in 2018 by the Korea Institute for Health and Social Affairs, and employed Latent Class Analysis. The demographic characteristics of each of the classified subgroups were identified through technical statistics. The types identified were multilayered depending on the imminence of death, perspectives of the last stages before dying, and the meaning of death in the context of social relationships. These types differed according to gender and subjective health conditions. Based on our findings in this study, we put forward policy suggestions about awareness improvement of personal and social levels, promoting on comprehensive death preparation, providing a system to reduce the cost of medical and nursing expense at the end of one's life, promoting of the right to self-determination regarding death, raising social attention to groups that are least prepared for dying well.

In Korea, recent women's educational standard is more higher than any other period but rate of using human resources is the lowest level among the OECD nations. As the reason of this phenomenon, the career choice attract attention. Traditionally, job is classified female-dominated job from male-dominated job, and most women still avoid male-dominated job. If this unequal concentrated phenomenon is relieved, diversity using of human resource will be available. For the purpose, this study try to determine the experience structure and the career decision-making process of the female undergraduate who want the male-dominated job through the qualitative study method, and to determine factors that work negative or positive on the process to use for the career consult. Grounded theory based data analyses resulted in 61 concepts, 27 sub-categories, and 12 categories from the recorded data of 8 female undergraduates who want the male-dominated job. The core category was "For the special life, keeping challenging with the will". A paradigm model consist of the casual condition, central phenomenon, contextual condition, intervening condition, actions/reactions and the result was proposed. And the participants went through five stages with time in their career decision-making process: the stage of awareness about the trait and aspiration, the stage of internal determination, the stage of support and accept, the stage of challenge and overcome, and the stage of affirmation and confidence. Implications of the findings and suggestions for the future research are discussed.

This study aimed to develop an e-PBL program for high school students using COVID-19 related data and to investigate the impact of the developed program on students' science core competencies. For this, the e-PBL program was developed in consideration of the characteristics of learners and e-PBL, and a science core competency analysis framework. The program was applied to 26 general high school life science club students. Test for science department core competency was conducted before and after class by questionnaires and their conversation data during class was collected and analyzed by the framework. As a result of the study, the developed program was effective in improving five science core competencies. In the results of the analysis of the science core competency questionnaire, there were significant effects on scientific thinking ability, scientific inquiry ability and scientific problem solving ability. Unlike in the results of the questionnaires, the five sciences department core competencies appeared evenly in student discourse analysis. Among them, scientific communication ability and scientific participation and lifelong learning ability did not show significant results in the questionnaire, but in the discourse analysis results. Both abilities were the most evenly displayed competencies through the program stages. Through the study, we expect that the program is possibles to be useful instructional material to make high school students increase science core competencies.

It has recently be emphasized in science education that lessons that can develop "scientific participation and action" should be implemented to scientifically recognize various problems and respond to them as well as risks that occur in real life. This study aims to analyze the characteristics of scientific participation and action lessons as perceived by the preservice primary school teachers. To do that, the researchers collected and analyzed the lesson plans designed by the preservice teachers based on the achievement standard related to noise for grades 3-4 in 2022 revised science curriculum. Focusing on the stages of "problem recognition," "data collection and analysis," and "implementation and sharing," the results identity the four main characteristics as problem-solving activity, inquiry activity, investigative activity, and activity that encourages practical actions. The two or three features were found to be combinated in a lesson depending on its context. In some cases, only one feature was seen in a lesson. Based on the results, educational implications were discussed in terms of the teaching and learning methods and teacher education for implementing scientific participation and action.
