Today, banks around the world are making great efforts to adapt to the rapidly changing internal and external environment changes caused by the development of IT technology and to gain a competitive advantage in the market. In particular, in line with the rapid growth of smartphone usage, financial services are also provided in a variety of ways using Fintech, and one of the fastest growing areas is mobile simple payment. Mobile payment service is a financial service that pays the purchase price using a portable mobile device. As fintech, a convergence of financial services and information technology, it is recently used not only in financial services, but also in various industries. It is used in all fields where payment functions such as distribution are available. In the case of mobile cards, it shows that the usage rate of people in their 20s and 30s is increasing very much, so it can be said that the use of mobile payment services will continue to increase in the coming future. We know that simple payments are being used. However, it can be said that the research on the use of mobile payment services by these teenagers is somewhat incomplete. Therefore, this study investigated what factors are important for Korean teenagers to use mobile payment services. As a result, among the five hypotheses presented in this study, all hypotheses were adopted except for , which states that cash usage habits have no effect on innovation.

To restore the ecological function of contaminated soil and maximize the ecological services provided by the soil, besides the toxicity orrisk caused by pollutants, the functional aspects of the soil ecosystem should be considered. In this study, a method for evaluating the health of cleaned soil was presented, and the applicability of the proposed evaluation method was examined by applying it to soil treated with washing and landfarming. Productivity, habitat, water retention capacity, nutrient cycling, carbon retention capacity, and buffering capacity were used as soil health evaluation indicators. The results showed that the soil health was not completely recovered after remediation, and even in the case of the washed soil, the health was lower than before remediation. On the other hand, there was no significant change in soil quality due to oil pollution, but soil health deteriorated. Unlike the slightly improved soil quality after landfarming treatment, soil health was not completely restored. Therefore, the results of this study indicate that it is desirable to consider both soil quality and health when evaluating the remediation effect. The soil health evaluation method proposed in this study can be usefully utilized for the sustainable use of cleaned soil and to promote ecosystem services.

As the Korean economy grew, employment expanded steadily, with the number of economically active people increasing and the employment-to-population rate also increasing. However, the working age population started to decline in 2017, and the employment of women and young people has been sluggish. The proportion of non-salaried workers in Korea is much higher than in other OECD countries, and is also excessive, considering Korea's income levels. In addition, the proportion of non-regular workers and the proportion of workers employed at small companies are particularly high among salaried workers. In light of these characteristics of Korean employment, the urgent problems facing the employment structure can be summarized by the deepening dual structure of the labor market, the increase in youth unemployment, sluggish female employment figures, and an excessive share of self-employment. Overall, it is seen that labor market duality is the main structural factor of the employment problems in Korea. Therefore, in order to fundamentally address this employment problem, it is necessary to concentrate policy efforts on alleviating labor market duality.

The Modern Total Property Theory is the social reform theory which emerged in the 2000s in Japan, which was suffering from the social issues similar to Korea - depopulation, aging society, centralization of metropolitan area, extinction risk of local provinces, and low growth. The theory aims to resolve social problems through the total property of spaces including land. The Modern Total Property Theory focuses on the issue of absolute land ownership. The absolute land ownership, which became the leverage of the economic growth after the Second World War, will not function properly in the future downsizing society. The existing ownership system functioned based on the premise that the value of land or buildings will be maintained or increase due to the existence of demand. However, large numbers of the ownerships that have no value will appear. However, since land or building cannot be touched even after they are let alone because they are bound by absolute ownership, the measure of turning the ownership of land or building into total property by establishing the subject of total property is being suggested. For this aim, the Modern Total Property Theory suggests that the bilateral relationship between state and individual be converted to the trilateral relationship among state, individual, and intermediate organization by inserting a middle clause in the modern law which is based on dual clauses - state and individual. Furthermore, since the Modern Total Property Theory is a macroscopic design for the reproduction of city and land and includes the legislation on the social policy level, it will provide the diagnosis and the prescriptions toward the social issues in Korea and adequate implications toward the reform direction of future social policies and judicial system.

Recently, the number of pet-owning households drastically increased and many people took their pets as lifelong companion animals and look after them like their children. Pet business has continued to increase gradually and the need for pet supplies has increased, too. Though there are a variety of pet supplies in pet dog market which takes up many parts in the pet market, there is no design guideline on pet supplies. Thus, there are many wrong pet supplies design created by wrong idea of people. Therefore, this study aims to suggest the guideline on pet supplies design focusing on the pet-monitoring system among the various pet products. So, the pet-monitoring robot was designed to monitor pet simply using smartphone anywhere on the trip and feed by using bowl that control the signal. This study figured out types and function of existing IP camera, reflected the behavior and physical characteristics of pets and suggested the design guideline which is minimum required as pet-monitoring products. Also, trial product for which design guide was applied was produced to observe the pet behavior and identify problems while operating trial product. However, there was limit in securing data and study period to examine the satisfaction of various pets since the subject of this study was dog and it's required to conduct follow-up study by observing continuously and improving the problems in future to secure more data.

This study analyzed the relative operational efficiency and impact factors of regional public hospitals to present benchmarking points for enhancing the efficiency of inefficient regional public hospitals. The survey targets collected and utilized the internal resources and management performance data from 34 regional public hospitals in Korea over the past five years, from 2014 to 2018. The final 33 regional public hospitals were surveyed, excluding Jinan Regional Public Hospital, which opened in 2015, the middle of the survey period. The general characteristics and input/output variables were analyzed by frequency analysis and technical statistics analysis, and Data Envelopment Analysis was performed to measure the operational efficiency index and relative comparison. According to the study, there were 11 efficient hospitals (33.3%) and 22 inefficient hospitals (66.7%). Of the 22 inefficient hospitals, 13 (IRS: Increasing Returns to Scale) required scale expansion, and nine (DRS: Decreasing Returns to Scale) required scale reduction or rebalancing. The significance of this study was that an analysis of the relative efficiency and influencing factors presented specific alternatives or directions that could help enhance the efficiency of the growth of regional public hospitals, sustainable management, and expansion of publicness.

One of the most conspicuous characteristics of a business model that pursues expanding customer relationship is that it tries to lock in customers by encouraging them to repeat purchase in the long-term with the help of "Follow" function in Social Networking Service (SNS), which enables producers to automatically register the customers as potentially important ones and to offer them customized marketing services. In the value chain of the agriculture sector, producers of agricultural products can use SNS functions to provide loyal customers with valuable information and experiences such as the real-time information of their farm and products, hidden stories about the whole process from seeding to harvesting, and the storage and cooking methods of their products. These activities help the producers invoke customers' desire to live in the farm and to grow the products themselves. They also raise the accessibility of the producers' websites as customers are able to share a variety of news and knowledge such as the release of new products. This means that the producers's websites are now functioning to enable the producers to perform sales and promotion related activities. It is a big leap from the traditional e-commerce business model where sales and promotion of a product were separated and could be connected only through outside links. This two-way, viral characteristics of marketing services using SNS facilitate customers to share product information and their purchase experience with each other, which leads to more effective and efficient communication within the customer community.

The aim of this paper is to describe a long-term trend toward earlier retirement and its reversal since 1985 in the United States, together with changes in socioeconomic conditions and social-policy programs which have contributed to this new development. The American people's recent propensity to retire at relatively younger ages was mainly a result of secular increase in individual wealth that had made it possible for them to enjoy higher standard of living without their participation in labor market activities at older ages. In addition to the introduction of compulsory retirement system, both social security retirement pension program and corporate pension system have also contributed significantly to the declining retirement age and its reversal around the mid-1980s. This paper pays full attention to the set of social policy programs which are currently being used to sustain the recent reversal in ages at retirement. The basic question to be raised here, however, is about whether or not the U. S. government will ave to continue to implement the social policies and programs used to discourage the elderly from retiring at relatively younger ages in the future. In this paper, it is argued that labor productivity growth and improvement in work attitude prior to retirement will help the elderly find little difficulties in having higher standard of living, despite their further lengthening of life expectancy at birth and post-retirement survival chances, the latter being often called the "third life". Most American people hope that the social-policy programs that have promoted early retirement will remain unchanged in the first part of the 21st century while they will put significant financial burden on their future descendants who have to work in the paid labor market. Taking this observation in consideration, this paper concludes that the U. S. government has to focus more on developing the programs that improve work propensity and labor productivity among the currently working-age population rather than continuing to implement the programs that sustain the recent reversal in retirement ages.ment ages.

The purpose of this present study is to empirically analyze the variables affecting socio-economic performance of social enterprises. For this purpose of 107 enterprises, located in Seoul, was performed under the hypothesis that the authentication properties (authentication type, authentication year) of social enterprises will affect the socio-economic performance. The analysis showed that first; authentication type among the characteristics of social enterprises showed significant effects on the social performance. Second, authentication year among the characteristics of social enterprises showed significant effects on the economic performances. In addition, since the job-creating type showed higher social performance, it would be desirable to raise the certification rate of this type in the future. The analysis implied that longer the years of accreditation, the greater positive effects on the socio-economic performance of social enterprises was shown. Therefore, the present study suggest the need to diversify support policies according to the number of authentication years in order to secure sustainability by maximizing the socio-economic performance of social enterprise because the monolithic support is not very effective for continued growth and self-reliance of social enterprises.
