To cope with the potential risks associated with invasive alien species, the Korean Government implemented the Biodiversity Act in 2014. Among the alien species not yet introduced into that country, 24 have been designated as alert species. These include mammals, birds, fish, mollusks, insects, and plants that may invade and cause serious harm to the ecosystem. Approval from the Ministry of Environment is required to import or carry any of them. Although these measures are more advanced than those from the previous legal framework, several terms still need to be improved. First, the category of alert species should cover not only those not yet introduced but also those that are being raised or cultivated at aquariums, botanical gardens, and zoos. Second, for applicants who intend to import or carry alert species, the government must provide them with detailed standards for the ecological risk assessment of alert species as well as guidelines for their safe use in Korea to prevent their unregulated release from confinement facilities into natural environments. Third, tools and protocols should be developed for early detection and rapid responses to those escapes.

The sovereign state has the right to engage in self-defense or war with the approval of the Security Council when it receives an invasion of territory from a foreign country. War is conducted under the principle of the necessity and proportionality of self-defense. In case of cyber attack, proportional countermeasure must be made through attack means and effect analysis, and cyber weapons need to be classified for this purpose. Therefore, this study aims to provide a rational and legitimate response according to the necessity and proportionality of the self - defense right by suggesting definition and classification criteria of cyber weapons. In this study, cyber weapons were defined as "means of collecting, attacking, and protecting information using cyber technology in the cyber space according to military objectives. Based on existing weapon systems and public cyber weapons cases, cyber weapons were classified as (1) cyber weapons for information gathering, (2) cyber weapons for attack, and (3) cyber weapons for protection. We suggest the considerations for applying the proportional response according to this functional classification. In order to guarantee the principle of proportionality to cyber attacks in the future, the classification study based on the cyber weapon effect should be conducted. This study has conducted an exploratory study on the classification of cyber clusters which constitutes one axis of the proportionality principle.

In Korea, 'forest welfare' is officially included as a policy object and used as an academic term. The Korea Forest Service strives to provide a forest welfare services suitable for each life cycle from birth to death, and the public is highly aware of the need for these policies. The demand for National Woodland Burial Grounds is expected to increase as the interest in natural burials including woodland burial is increasing. As the demand for the Woodland Burial Grounds is increasing, there is only one National Woodland Burial Grounds currently available. Although other forest welfare facilities, such as natural recreation forests, must have undergone feasibility assessment according to relevant laws before approval of the designation, there are no institutions performing Woodland Burial Grounds feasibility assessments at the time. Therefore, it is necessary to consider the policies to cope with the increased demand. This study used GIS to prepare the basic data to be used in the process of selecting suitable forest locations. The area that cannot be used according to related laws was analyzed and the size of the possible areas in the state forests was assessed.

In the era of the global coronal 19 pandemic, there is a risk of cross-infection in hospitals at the stage where treatments and vaccines are currently being developed and marketed, so individuals should enhance their acquired immunity and generalize their living systems by the performance of copper ions in the social environment. In order to prevent the spread of infection, the need for anti-bacterial film and its efficacy were analyzed through anti-viral performance tests based on research and development cases of worldwide and immemorial time. he Korea Construction Research Institute (KCL) has received anti-bacterial performance certification and anti-viral test scores from the "National Approval Performance Certification Agency." At the time, NCCP 43326 Human Corona virus (BetaCoV/Korea/KCDC03/2020), which was approved by the Centers for Disease Control and Prevention, was introduced to ensure that the activity rate of infected cells was satisfied in the anti-viral performance test. Anti-proliferation measures for the Corona 19 virus require a quality clinical trial study comparing the experimental group within the glass space where the antiviral copper film is constructed with the comparator of the same condition without copper film.

Purpose: The purpose of this paper is to provide basic data in order to systemize the management of demand and supply of radiologic technicians, to pursue a fair regional distribution of educational institutions, and furthermore to keep reasonable medical treatment and fee. This research was carried out through the investigation of radiologic equipments and technicians according to the distribution of the population. Materials and Methods: We compared and analyzed the correlation between regional population, the number of clinics and hospitals, the number of medical imaging devices, and the number of radiologists and radiologic technicians in 5 cities without "Gu" administrative units in 2008. Results: 27,317 radiologic technicians have been produced since the administration of the national qualifying exam for radiologic technicians. About 18,000 radiologic technicians are currently working. There are 39 colleges or universities with Departments of Radiology and the admission quota is 2,120 students excluding one college. The ratio of radiologic equipments to radiologic technicians is 2.6 to 1. Conclusion: There is a dilemma in which some radiologic technicians fail to find appropriate jobs while some clinics or hospitals are in need of radiologic technicians. This dilemma is due to unreasonable regional discrepancies in pay system and welfare situation, and excessive profit-oriented recruiting system of clinics and hospitals. The increase of students of Radiologic Departments and approval of additional departments will end up with producing superfluous high academic degree holders, which is on the contrary to the government policy to produce more job opportunities. So the policy of increasing Radiologic Departments should be reconsidered.

The purpose of this study is to review the contents of the legislation(2015.5.12.) for shop key money concretely and to find an effective way in making an improvement of practical protection in the process of tenant's shop key money collection. From this point of view, this study tries to make some legislative suggestions as follows. First of all, the code of conflicting definition between 'shop key money' and 'shop key money contract' in the amended Commercial Building Lease Protection Act need to be harmonized with each other because they are likely to face potential problems in the protection of tenant's shop key money collction as well as risks for confusion. In the second place, it requires to strengthen the protection of tenant's shop key money collection by approval of direct opposing power of shop key money itself on condition that it satisfies a certain prerequisites. In addition, the ambiguous codes related to the landlord's disturbance should be distinctly arranged and the distribution principle of demonstration about landlord's disturbance on tenant's shop key money collection also should be made clear. Finally, the standard level of shop key money by region, business district, and category of business should be set and announced by Ministry of Land and Transport.

The Q&A board is widely used as a means of communicating service enquiries, and the need for efficient management of the enquiry system has risen because certain questions are being repeatedly and frequently registered. This study aims to construct a student-centered FAQ, centered on the unstructured data posted on the university homepage's Q&A board. We extracted major keywords from 690 postings registered in the recent 3 years, and conducted the semantic network analysis to find the relationship between the keywords and the centrality analysis in order to carry out network visualization. The most central keywords found through the analysis, in order of centrality, were application, curriculum, credit point, completion, graduation, approval, period, major, portal, department. Also, the major keywords were classified into 8 groups of course, register, student life, scholarship, library, dormitory, IT and commute. If the most frequent questions are organized into these areas to form the FAQ, based on the results above, it is expected to contribute to user convenience and the efficiency of administration by simplifying the service enquiry process for repeated questions, as well as enabling smooth two-way communication among the members of the university.

This study aimed to identify the mediating effect of nurse's communication on the relationship between nursing needs and nursing satisfaction in hospital patients. After IRB approval, this study was performed by administering questionnaires to 180 university hospital patients between April and June, 2017. Collected data were analyzed with SPSS 22.0. The average score of nurse's communication, nursing needs, and nursing satisfaction were $3.88{\pm}0.52$, $3.96{\pm}0.55$, and $3.74{\pm}0.59$ out of 5, respectively. There were significant differences in educational and therapeutic needs versus satisfaction. As for nurse's communication and nursing satisfaction, there were significant differences by patient's room. There were positive correlations among nurse's communication and nursing needs (r=.286, p<.001) as well as nurse's communication and nursing satisfaction (r=.524, p<.001), In addition, there were positive correlations between nursing needs and satisfaction (r=.488, p<.001). Nursing communication had a partial mediating effect between nursing needs and satisfaction, which showed significance in Sobel's test (Z=2.450, p=.014). Therefore, it is suggested that a continuous program for strengthening communication of hospital nurses is needed.

This study is about ionic water generator filter Recently, a lot of people feel deep interest in health and drinking water. And there are various types of water. Ionic water generator is a system with special function, and can be classified as a medical device and should be manufactured after approval from the Food and Drug Administration. Basically ionized water is different from the packaged and stored water. When the tap water or ground water passes through the various filters of ionic water generator, it turns to the purified water of pH7 ~ 7.5 and we can electrolyze that water into anion and cation by diaphragm. And in negative electrode side, we can get alkaline water with calcium ($Ca^+$), potassium ($K^+$), magnesium ($Mg^+$), sodium ($Na^+$) for body. In general, we can change pH value from 5 to 9 of ionizer by controlling the level of electrolysis voltage in the ionizer. In general, 1stage (pH8), 2stage (pH8.5), 3stage (pH9), 4stage (pH9.5) are used as the alkaline ionized water, -1Stage (pH6.0), -2 stage (pH5.0) are used as the acidic water. But in early stage, the water that passed through filter was weakly alkaline water and that was problem. Therefore, when filter condition is stable, the pH and ORP value of water is different with the early one. the initial setting pH value of the ionizer was confirmed that changes significantly. In order to resolve this problem we need to wash filter for some period time and neutralize by acidification treatment of the filter.
