The "sharing economy" describes a type of business built on the sharing of resources - allowing customers to access goods when needed. While sharing goods has always been a common practice among friends, family, and neighbors, in recent years, the concept of sharing has moved from a community practice into a profitable business model. This study explores gaps between customers' actual usages and current policies on accommodation sharing by analyzing what needs to be done for the better establishment of sharing economy in society. The purpose of this study is to investigate perceptions of accommodation sharing by analyzing reviews and negative aspects that help resolve complaints and improve better services through policy establishment. This study investigates key attributes that influence business performance to improve citizens' decision-making for the usage of accommodation sharing. This study applies qualitative research by collecting demand- and supply-side reviews from selected registered accommodations using a random sampling procedure. This study finds that guests prefer entire house sharing with instrumental attributes related to properties. Entire house sharing of multiple dwellings shows business impacts in terms of high occupancy rate on the platform, while there are policy concerns with entire house sharing. The results provide policy and managerial implications by suggesting proper policies and considering relationships with citizens.

COVID-19 Archives are some of the Disaster Archives. It is necessary to collect disaster records produced in real-time at the disaster scene rather than start collecting records after the disaster recovery. Therefore, this study summarized the definition and purpose of disaster archives to understand the current status of domestic and foreign COVID-19 archives and examined overseas disaster archive collection policies that can be referenced in establishing a COVID-19 archive collection policy. In addition, surveys and interviews were conducted on institutions that establish and operate related archives at home and abroad. As a result, record collection Improvement plans for the COVID-19 archive were proposed: Firstly, in terms of collection policy improvements, the essential elements identified in the survey were selected as additional collection policy elements. Secondly, diversification of participants' groups requires the introduction of clear definitions of collection targets, diversification of promotional methods such as recording record contents through collaboration with related departments, and improving copyright issues that limit record donation. Thirdly, participatory record collection methods with efficient questionnaires in participatory forms and privacy issues are proposed as improvement plans.

In the field of access control, policy conflicts must be solved and various related solutions are being researched and developed. In order to resolve the policy conflict problem, it is necessary to first identify the cause of the conflict, and as a minimum condition, it is necessary to detect the contextual elements of the policy that have influenced the policy evaluation decision. Although the XACML policy language specification provides a way to define this, the policy creator currently has limitations in not clearly describing the causes of conflicts in every contextual elements. In addition, in order to identify the causes of the policy conflict, it is necessary to acquire additional information such as other policy combination algorithms, in addition to these contextual factors. In this paper, we propose an effective method to identify contextual factors, as well as to locate additional information that cause policy conflicts.

The gases emitted from internal combustion engines using fossil fuels are causing many social problems, such as environmental pollution, global warming, and adverse health effects on the human body. In recent years, the demand for renewable energy has increased, and government policy support and research and development are also active. In the collecting part of a solar energy system, which is widely used at home, propylene glycol (PG) (anti-freeze), as a heating medium, is mixed with water at a fixed value of 50%, and the heat is transferred to the collecting part at subzero temperatures. On the other hand, when leakage occurs in the heat medium in the heat collecting part, supplemental water is supplied to the solar heat collecting part due to the characteristics of the solar heat system, so that the concentration of antifreeze in the replenishing water becomes low. As a result, the temperature of the solar heat collecting part is lowered resulting in a frost wave, which causes economic damage. The purpose of this study was to develop a device capable of controlling the antifreeze concentration automatically in response to a temperature drop to prevent freezing of the heat collecting part generated in the solar energy system. The electrical conductivity of the H2O component was larger than that of PG, and the resistance increased with decreasing temperature. The PG concentration control values of 40, 50, and 60% should be controlled through calibration with a PG concentration of 39.6, 50.7, and 60.1%.

This paper presents tile efficient polling architecture for simple network management protocol (SNMP). Now a day, tile internet traffics have been increasing rapidly within a few years as the subscriber's network to connect internet is provided commonly. With this trend, the network management traffics also make the same phases. To provide numerous higher Quality services to the customers, the management traffic must be controlled within the permitted limit. This paper proposes the policy-based felling architecture for SNMP MIB with several parameters and suggests the data collecting layer architecture for the efficient polling.

Korea's quarantine response to the novel coronavirus (coronavirus disease 2019 [COVID-19]) pandemic is based on the sacrifice of health professionals, especially public health doctors (PHDs) who were called out first and put in the first place in the country. PHDs performed major quarantine tasks, such as collecting samples from screening clinics and epidemiological investigations, in various parts of the country, including the Daegu area, where the first large-scale COVID-19 confirmed cases in Korea and explosively increased. Because of their position as fixed-term civil servants, however, PHDs' professionalism as doctors was ignored, and they were not properly compensated for their work. They were also exposed to problems such as a high risk of infection, mental suffering, and various human rights violations. We must prepare concrete measures to improve the fundamental treatment of PHDs and protect their human rights in order to prepare for a possible infectious disease pandemic in the future.

A field of privacy protection lacks statistical information about the current status, compared to other fields. On top of that, since it has not been classified as a concrete separate field, the related survey is only conducted as a part of such concrete areas. Furthermore, this trend of being regarded as a part of fields such as informatization, information protection and law will continue in the near future. In this paper, a novel and practical way for collecting and storing a big amout of data from 110,000 privacy policies by data controller is proposed and the real analysis results is also shown. The proposed method can save time and cost compared with the traditional survey-based method while maintaining or even advancing the accuracy of results and speediness of process. The collected big personal data can be used to set up various kinds of statistical models and they will play an important role as a breakthrough of observing the present status of privacy information protection policy. The big data concept is incorporated into the privacy protection and we can observe the method and some results throughout the paper.

Purpose: To understand the development of nursing education of North Korea after 1945. Method: First, collecting primary sources published in NK. Second, collecting secondary sources published in South Korea. Third, interview with South Korean medical personnels who visited NK. Forth, interview with medical personnels who escaped NK. Result: After 1945 NK increased health care facilities in short time and had the policy of training medical personnel in short time. Nursing education was focused on the basic practice. NK could begin free medical treatment for the laborer in 1947. Post Korean War restoration and free medical treatment system of national level in 1950s and 1960s served to the health promotion of NK population. The medical personnel training policy continued and the number of R.N. in NK had increased 13 times in 15 years. NK has tried to increase the quality of health care service and medical personnel since 1970s. Nursing education in medical colleges is three-year course but 6 month training courses in general hospitals continue. They focus on primary prevention and oriental medicine in nursing curriculum reflecting the characteristics of NK medial care. But English and high technology is very poor, and there is no computer related curriculum. Conclusion: nursing education in NK has developed reflecting the changes of NK society and health care since 1945. After 1980s NK is in deep economic depression and it is hard to recover from the state with their hands. In this state, we cannot expect the development of nursing education in NK.
