This study analyzed the effects of labor aging on labor productivity using panel statistics of 16 local governments from 1995 to 2017. The aging of the labor force, defined as the proportion of workers aged 60 or older in total employment, in the results of the panel regression analysis considering regional fixed effects and various adjustment variables, has a very consistent and significant negative effect on labor productivity. For every 1% increase in aging, labor productivity decreases by about 0.14 ~ 0.20%. In addition, the per capita capital stock and human capital considered as adjustment variables contributed to the increase of labor productivity, and the unemployment rate, which is a proxy variable of the economic fluctuation, has a significant negative effect on labor productivity as expected. The coefficient of the industrial structure, which represents the share of the service industry in the whole industry, was positive, but is not significant. The results of this study suggest that the design and construction of economic and educational policies that can maintain and expand human capital are necessary to curb the reduction in labor productivity expected by the aging workforce.

The purpose of this study is to investigate the influences of Science Core schools on students' positive experiences about science (PES) through in-depth interviews with teachers in charge of science core schools. In-depth interviews with teachers were conducted to explore the factors that led to the effectiveness of science core schools in improving the student's PES in light of operational characteristics of science core schools as leading schools, characteristic factors of science core schools on students PES, and improvement plans and requirements of science core schools as leading schools, as well as implications for general high schools. In the case of science core schools, the teacher's enthusiasm for science teaching encouraged students' participation in science classes, promoted students' interest in science other than science-core classes, improved students' inquiry and research skills, increased students' competencies such as communications and collaboration by improving science instructions, and affected career search and exploration based on interests in science experiences. Based on the results, ways to spread the characteristics of science core schools to general schools' curriculum implementation are suggested including providing opportunities to experience the value of science study, to experience science and engineering careers through senior students, to participate in team projects and self-regulated science inquires, and so on.

Our society is aging rapidly. In this super-aged society, the increase in healthcare costs are considered a national problem that undermines the sustainability of social security. Various services for healthcare for the elderly have been promoted to address this. However, most of them have focused on healthcare after the outbreak of chronic diseases and lack preventive healthcare. Most of the preventive healthcare projects are only pilots. In this paper, the current status of health care services for senior citizens at home and abroad was analyzed and based on this, the limitations and improvements were analyzed to propose the establishment of IoT-based Total Silver Care Center. IoT-based Total Silver Care Center may be conveniently monitored the health status of the elderly through various sensors, medical devices, and smart bands. And based on this, it can improve the quality of nursing services through time-saving and work efficiency of nursing providers. In addition, health care interventions may be provided in a timely manner if there is a change in the health status of users. And real-time imaging systems can help overcome mental difficulties.

In this study, we examine the concept of social value which is the main philosophical foundation in government innovation pursued by Moon Jae-In government and analyze the case of government innovation which was promoted by specific local governments. The purpose of this study is to discuss the implications for the government innovation through the case study of local autonomous organizations. The studied local government is an institution that has received excellent evaluation of government innovation for the realization of social value by Ministry of Public Administration and Security. In this study, we conducted in-depth interviews with local governments and youths and examined the success factors of government innovation through active participation in community issues. First of all, institutional support such as ordinances is important for encouraging the participation of community members. It is also important for local governments to lead their own change and listen to their voices from a consumer perspective, not from a supplier perspective. In addition, significant importance of the incentive system that could induce continuous participation in community problems was found. In this way, it is possible to establish a continuous system to approach the problem of local community as consumer perspective, not supplier perspective, and solve the problem together.

A random chat application is a type of social dating application that helps people find a lover or spouse by randomly connecting and providing services such as text, voice and video chat. Recently, there has been globally a rapid increase in its use due to the fact that it provides people to quick and convenient encounters at low cost. However, it is used as one of method to prostitute or to trade drugs and become a cause of violent crimes due to various criminal occurring after actual meeting between app users. For this reason, a random chat application is likely to provide proof of prostitution or drug trade and clues to arrest rape, kidnapping and murder suspects. Thus, it is necessary to analyse random chat applications from the viewpoint of digital forensics investigation, but there is no related research at all. Therefore, in this paper, we analyzed artifacts of 6 Korea random chat application's user behaviors; Ranchat, AngTalk, SsumgThing, DaTalk, EveryTalk and Sail. As a result, we found that it is remain on mobile device that time and contents of message transmission/reception, sender/receiver, friend profile and user account creation time when user is using the applications.

This study investigated the effects of goat blood serum (gBS), goat follicular fluid (gFF) and gonadotropin (FSH) on the in vitro maturation, fertilization and development of Korean native black goat oocytes. Our results indicate that the gBS combined with FSH treated group showed significantly higher maturation rate than the other groups. Furthermore, blastocyst formation rate was significantly increased in all treated groups, and gBS and gFF combined with FSH treated groups were higher than other groups. However, gene expression levels of BMP15 and GDF9 in COC, both oocyte maturation related genes, remained unaffected after 24 h maturation. The results of the present study indicate that supplementation of the maturation medium with gBS, gFF and FSH is efficacious in improving the in vitro maturation, fertilization and development of Korea native black goat oocytes.

This study investigated the effects of national science leading school programs on students' positive experiences about science (PES) and teachers' perceptions of curriculum implementation factors affecting students' PES. For this study, Test for Indicators of Positive Experiences about Science (TIPES) was administered to a total of 11,488 students from 117 national science leading schools and 1,315 students from 50 normal counterpart schools. In addition, a total of 105 teachers were given a survey asking their curriculum implementation levels and perceptions on importance and performance levels of each identified factor that was known to influence students' PES. Students' total PES scores and scores in five sub-components of PES were widely varied across science leading school program types. In general, participating teachers reported common curriculum implementation factors that most positively affected students' PES including 'science-related activities out of school,' 'student-centered research projects,' 'ICT-related materials' and 'performance assessment.' Based on these results, implications for science education were discussed.

Memoirs of Hadrian is a representative historical novel of Yourcenar which focuses on the personal history of the Emperor Hadrian of Rome and on his inner side. This study focuses on the love story of Hadrian and Antinous, and examines the specificity of their love in relation to the homosexual culture of ancient Greece, especially pedophilia. Through this topic, we have analyzed the causes of the tragic death of Antinous by capturing the progression of a cycle of pedophilia, a young boy (Eromenos), that grows into manhood as Erastes. This study defines the emperor's efforts to restore Antinous in his own way after a failed love, as a passion toward totality. Therefore, we see the two figures as a process of mythology in which the pie of tragic destiny is transferred to the myth of androgyny that becomes one body and one unity in pedophilia. We see this ancient myth as a concept contrasting with the sense of pedophilia of the emperor, who arbitrarily distinguished between love and pleasure, and believed that the affection calculated with calmness and indifference was a harmony of love. This study explains the intention of Yourcenar in her work to present the value of empathic love, especially sacredness and sublime, which should be a part of sensual love. It also reminds us of the importance of sagacity that a person with power must hold in the happiest and most loving moments of life.
