Contemporary society, the era of the 4th industrial revolution, has been enjoying a boom in the cosmetics industry due to the launch of cosmetics through new technology development due to the interest in the beauty industry. However, the cosmetics industry is booming, but dry eye syndrome, skin trouble, Hormonal disturbances, and many other side effects. In order to prove the universal use value of pine needles as a natural cosmetic material that can complement the side effects of existing chemical ingredients cosmetics harmful to human body, and to propose a roll model of desirable natural cosmetics, DPPH radical scavenging activity, ABTS assay, and flavonoid content were studied. The results showed that both the DPPH radical and ABTS radical scavenging activity increased in both the $70^{\circ}C$ and $100^{\circ}C$ pine water hot water extracts. The extracts from the pine tree extracts at $70^{\circ}C$ and $100^{\circ}C$ showed $32.0{\pm}2.5mg\;QE/ml$ and 116.8 A total flavonoid of ${\pm}5.5mg\;QE/ml$ was detected. Therefore, it is considered that the pine needle hydrothermal extract having a large amount of antioxidant which is advantageous to human body is highly applicable as a natural cosmetic material harmless to the human body.

Objectives: There are few studies which reflects of each generation's own features, of the New Middle Age and the Elderly's hearing status and their quality of life even though the population of old age has been weighted as baby boom generation's entering into old age. This study is to identify the effects of the new middle age and the elderly's hearing status on their quality of life and to prepare the customized health policies for their health promotion and quality of life improvement as well as the base line data for hearing enhancement programs. Methods: This study was analyzed using the data of the 7th term of the National Health and Nutrition Survey of the Disease Management headquarters. Out of 8,150 adults over the age of 50 who participated in the hearing test, 3,306 were selected and analyzed. Results: At the result of identifying the correlation of hearing status and the quality of life between the New Middle Age and the Elderly, it was confirmed that hearing loss affects low quality of life. The average of quality of life between the New Middle Age and the Elderly was 0.95 and 0.85 each, resulting in higher quality of life in New Middle Age than in the Elderly. The factors affecting the quality of life of the New Middle Age were the level of the education, household income, the type of health insurance, subjective health status. The factors affecting the quality of life of the Elderly were gender, the type of health insurance, subjective health status. Conclusion: Hearing loss of the New Middle Age and the Elderly affects their low quality of life. Therefore the development and the provision of policy program is needed, so as to maintain and manage hearing through age-specific health education. It is expected that the second half of the New Middle Age's life will be much happier, if not taking the treatment-oriented approach of hearing loss only but strengthening the education needed for the maintenance and the management of healthy hearing at their work place, where 50 and 60 generations' workforce has been increased.

The purpose of this study was to develop EM media for water treatment and to remove nitrogen and phosphorus which cause water algae boom in water system. The ideal mixing ratio of raw material such as clay: zeolite: vermiculite: activated carbon for manufacturing the EM media was 10: 2.5: 0.1: 2, and the calcination temperature was $700^{\circ}C$. The comparison of the physical properties of manufactures using distilled water and EM activated liquid as the material mixture are as follows. Porosity and density of EM media were 39.98 % and $1.13kg/m^3$, adsorption efficiencies of nitrogen and phosphorus were 69.3 % and 38.9 %. In contrast, porosity and density of distilled water media were 37.80 % and $1.11kg/m^3$, and adsorption efficiencies of nitrogen and phosphorus were 62.5 % and 37.8 %. The adsorption rate of nitrogen and phosphorus in the EM media was higher than that of the distilled water made one by 6.8 % and 1.1 %, respectively. The adsorption characteristics of the media to nitrogen and phosphorus could be expressed by the Freudlich adsorption isotherm. The change of calcination time did not affect the adsorption efficiency of phosphorus and nitrogen when EM media was formed, but it was considered that it affects the strength of media. Nitrogen removal efficiency was the best record in 4 hours of calcination time and 3 hours of calcination time in phosphorus removal efficiency.

This study pays attention to the restricted use and the possibility of standard position of contingent workers in Brazil. The labor market of Brazil has been developed by formal and informal labor sector, and informal sector includes various precarious workers as well as contingent workers. According to Brazilian Statistics Department, not contingent workers but informal labor focused in this paper have been slowly decreased since year 2000. In this context, this study investigated on the reasons of decreasing contingent employment in Brazil. The results demonstrate that decreased informal employment and instead increased standard workers could not be interpreted by recent the Braizil's economic boom. Along with literature review, the author conducted the case study regarding employment of contingent workers at six large foreign companies in Sao Paulo. The results of this show that the use of contingent employment was prohibited in regular daily works by the labor law and thus firms employed contingent workers in only temporary positions. Further, firms often promise standard positions for contingent workers when temporary employment contract was terminated since there is little or no exist of the differences of wage between standard and contingent worker in terms of 'same work same wage' and 'minimum wage'. In here, labor unions play a key role in employment change from contingent position to standard job. Consequently, decreasing of contingent workers and stepping stone to regular jobs seems to be triggered by both legal regulation on contingent employment and strong unions. This institutional perspective may extend the theoretical view on the use of contingent workers, and the author discuss that Brazil's case could provide practical implications to Korean labor policy.

The purpose of this paper is to study the development process of our native verses from the Three Kingdoms Period to the Goryeo Dynasty. The contents of the discussion can be summarized as follows. Typical form of "Sanega" from the Three Kingdoms Period to the late Silla/ early Goryeo Dynasty is a well organized 3-layered structure representing the contents of enlightenment of a high priest. Sanaega has a poetic style characterized by distinct literary features compared to other native verses in the same era. The reason is that 10-line Hyangga improves its poetic level as it is aware of Chinese poetry. As it enters the Goryeo Dynasty, this literary composition starts to change. In other words, Sanega declines and quatrain emerges in the front of literary history. Unlike the Three Kingdoms Period ~ the late Silla/ early Goryeo Dynasty, development of quatrain results from that native verses enhances the characteristics of song rather than poem in the Goryeo Dynasty. Native verses form the mutually complementary relationship by adjusting the position as the song rather than competing with it as the poem as Chinese poetry becomes more common. In the Goryeo Dynasty, Sanaega declines and Sijo emerges in literary history, because native verses have been developed in the poetic form to freely express general emotion and to be more loved from the public. It is in the same vein as a native verse in the form of quatrain raises its vitality by enhancing the characteristics of the song through the adjustment of its position compared to Chinese poetry.

It has already been a few years since the word Fintech in Korea started to attract attention. These days, they believed that Fintech was just a boom, but these days it is recognized as a catalyst for financial transformation. Large venture companies are also launching demonstration experiments by creating new organizations that can respond to Fintech. It feels like a big tide is coming to the cautious and conservative financial industry. Finance is made up of digital information. Fintech is an evolutionary process in which finance, expressed by digital information, is transformed into information technology (IT) and human economic activities are reorganized. It is FinTech. You won't be able to understand the real effects of Fintech by sticking to individual applications like remittance payments or household account book services. Fintech is an innovation that changes the structure of economic activity itself. In fact, it is from now on that a big impact will come. In other words, now is the time when we are thinking of a dream that we have not yet dreamed of. In this paper, I will examine how fintech originated, spread to Korea, and how it intends to change Korea's finance in the future. Financial institutions have used the fruits of information technology advances in the direction of pursuing stability and stability, without major changes in the way they work. However, the movement of Fintech that started in Silicon Valley in the United States shows that the fruit can be used in other directions. The fruit of technological progress is expected to expand year by year in the future. It is a request of the times to use it to improve user convenience and to pursue innovation that is beneficial to society. We expect the flow of Fintech to accelerate innovation in the Korean financial industry.

The shipping industry has experienced significantly fluctuated while decline in long-term and boom in short-term period due to the continuous recession of the shipping industry since the 2010s and during the recent COVID-19 pandemic. This study aims to suggest implications for securing manpower and personnel policy by analyzing the effects of job environmental factors of a liner shipping company on job satisfaction and turnover intention and differences between land and marine workers. For the analysis, the job environmental factors of a liner shipping company were divided into work character, relational factors, personnel characters, and remuneration factors, and then structural equation model and t-test were conducted to test the relationship between job satisfaction and turnover intention. As a result of the study, it was found that job environmental factors, such as work, relationship, personnel, and remuneration, had a positive (+) effect on job satisfaction, and job satisfaction had a negative (-) effect on turnover intention. In a comparative analysis between groups such as land and sea workers, it was found that the maritime workers group had higher job satisfaction and lower turnover intention than the land workers.

John Woo's A Better Tomorrow arrived at the turning point of Korean society between 1987 and 1988. The Hong Kong movie boom that started here reached its peak around the 1990s. What does this phenomenon mean? Hong Kong action films have functioned as an important resource for Korean young male subculture since the late 1960s. The audience of A Better Tomorrow matches the audience of previous Hong Kong films in a generational and gendered way. The fascination of Hong Kong action films by young Korean men from 1987 to 1991 has nothing to do with Hong Kong's political context. However, a certain affect is shared between Korean and Hong Kong audiences. It could be said to be the brotherhood within the struggling group. The affective economies of this fraternity embodies the broad solidarity of 1987, the solidarity of comrades seeking to resist the violence of the world. It also works on symbolic and practical gender bias. In other words, this loyalty is nothing but loyalty between the (male) brothers who are confronting the injustice of the world. This is the "translational possibility" of A Better Tomorrow.

No language can be separated from other languages and exist independently. When a language comes in contact with a foreign culture, they continuously affect each other and bring changes. Hallyu boom(Korean wave), which was derived from the emergence of K-drama and K-pop due to rapid developments in global scientific technologies and digitization after the 90's, affected the Chinese language. As a result, neologisms that are derived from the Korean language are being commonly used for making exchanges and becoming social buzzwords. Neologisms derived from Korean reflect the effects and results of language contact between the two languages. We examined the background and cause of Chinese neologisms derived from Korean based on the sociocultural factors and psychological necessity, and explained neologisms by using four categories of transliteration, liberal translation, borrowing Korean-Chinese characters and others. Despite having the issue of being anti-normative during the process of coining new words, neologism enriches Chinese expressions and is a mirror for social culture that reflects the opinions and understandings of young Chinese people who pursue novelty, change, innovation and creativity in linguistic aspects. We hope that it will serve as an opportunity for the young people in Korea and China to change their perceptions and become more friendly by understanding each other's language, culture and by communicating. We also expect to provide assistance in regard to teaching and learning the applications of Korean-Chinese language fusion at Chinese education fields.
