Technological advancement and demand of sUAS (small Unmanned Aircraft System)are rapidly growing, which makes the current legal system unable to follow. Currently, Aviation Security Act and its subordinate law exclude the registration and certification for non-commercial purpose sUAS weighing less than 12kg. Despite this sUAS being the most popular model for consumer, there is no way to regulate them legally. When there is sUAS crash accident, the operator legally responsible for the occurrence damage cannot be identified. It has been an issue for a long time with the concrete classification and registration of sUAS, but it has not been introduced yet. It is obvious that damages caused by sUAS will be transferred not only to operators but also to third parties. Discussions on liability insurance for these sUAS are actively being held. But first, it is necessary to identify who will be responsible for the damage caused by the sUAS. In other words, even with the liability system established, without clarified operator the damage occurred cannot determine who is responsible. According to the cases of America and Germany, they have enforced the law of registration and identification obligated to 200g or 250g sUAS. Therefore, it is necessary to prepare regulations on concrete classification and registrations to identify for noncommercial purpose sUAS as soon as possible in Korea.

Main Path Analysis (MPA) is one of the text mining techniques that extracts the core literature that contributes knowledge transfer based on citation information in the literature. This study applied various text mining techniques to abstract of the paper related with sense-of-place, which is published at Korea and abroad from 1990 to 2018 so that could discuss in a macro perspective. The main path analysis results showed that from 1990, overseas research on sense-of-place has been carried out in the order of personal identity, public land management, environmental education and urban development-related areas. Also, by using the network analysis, this study found that sense-of-place was discussed at various levels in Korea, including urban development, culture, literature, and history. On the other hand, it has been found that there are few topic changes in international studies, and that discussions on health, identity, landscape and urban development have been going on steadily since the 1990s. This study has implications that it presents a new perspective of grasping the overall flow of relevant research.

As the industry develops in Korea, the use of hazardous chemicals is increasing rapidly and chemical accidents are increasing accordingly. Most of the chemical accidents are caused by leaks of hazardous chemicals, but there are also accidents in which all the substances are released instantaneously due to sudden high temperature/pressure or defection of the storage tanks. This is called catastrophic failure and its frequency is very low, but consequence is very huge when it occurs. In Korea, there were 15 casualties including three deaths due to catastrophic rupture of water tank in 2013, and 64 instances of failures from 1919 to 2004 worldwide. In case of catastrophic failure, it would be able to overflow outside the bund that reduces the evaporation rate and following consequence. This incident is called overtopping. Overseas, some researchers have been studying the amount of external overflow depending on bund conditions in the event of such an accident. Based on the previous research, this study identified overtopping fraction by condition of bund in accordance with Korea Chemicals Controls Act Using CFD simulation. As a result, as the height increases and the distance to the facility decreases while meeting the minimum standard of the bund capacity, the overtopping effect has decreased. In addition, by identifying the effects of overtopping according to atmospheric conditions, types of materials and shapes of bunds, this study proposes the design of the bund considering the effect of overtopping caused by catastrophic failure with different bund conditions.

The purpose of this study is to provide policy recommendations for manpower planning by forecasting the supply and demand of Medical Technologists. Supply was estimated using an in-and-out movement method with a demographic method based on a baseline projection model. Demand was projected according to a demand-based method using the number of clinico-pathologic examinations taken for Medical Technologists. Over- or undersupply of Medical Technologists will depend on the productivity scenario and assumptions and ultimately on governmental policy direction. In other words, whether the production of Medical Technologists is higher or lower than the current level depends on the government policy to consider insurance finances. In this study, we assessed 'productivity scenario 3' based on the productivity as of 2012, when the government's policy direction was not considered. Based on the demand scenario using the ARIMA model, the supply of Medical Technologists is expected to be excessive. This oversupply accounts for less than 10% of the total and therefore should not be a big problem. However, given that the employment rate of Medical Technologists is 60%, it is necessary to consider policies to utilize the unemployed. These measures should expand the employment opportunities for the unemployed. To this end, it is necessary to strengthen the functions of laboratories in the public health center, to increase the quota of Medical Technologists, to assure their status, to establish a permanent inspection system for outpatient patients, and to expand the export of Medical Technologists overseas.

With the breathtaking stride beingmade in the field of biotechnology, biocatalyst research using genetically modified microorganism (GMM) is actively being pursued in food industry. However, domestic food and food additive regulation standards and the number of examination management examples currently used in industry is lacking significantly. Up till now, there are only 6 examples of domestic GMM examination and approval cases for food production purposes and furthermore they are limited to the production of functional sweeteners. Domestically, although GMM is developed as a processing aid (contained use), if they are used in the production of food, the safety of GMM, including environmental safety, is evaluated. Also the produced food or food additives using GMM need to be separately examined and approved as a novel food. On the other hand, imported products produced using GMM need to gain approval for the final product only. Thus the expense and the time to obtain regulatory approval is advantageous for imported products versus domestically produced products. This commentary is written to create the opportunity to reform the current domestic food GMM regulation by comparing and discussing domestic and foreign case analyses of safety evaluation of GMM and related regulations.

The introduction of smart technology provides accuracy, safety, and efficiency to both physicians and patients. Although interest in a clear aligner is increasing among users worldwide, the current clear aligner requires a visit to the hospital every one or two weeks for replacement, which is a very cumbersome process. There is also confusion among dentists and patients because about 40 to 80 devices are made, and calibration is done based on the order and duration of the clear aligner. Therefore, this study designed and developed a clear aligner management system so that communication between the patient and dentist can be smoothly performed by inserting the QR code into the transparent correction device. As a result, the size of the QR code was recognized as $6{\ast}6mm^2$ which can be used in the oral and the recognition distance was 100% within 12 cm. Since the dentist can remotely manage the patient with the proposed system and improve the correction effect, it is possible to manage patients abroad, as well as domestically.

This study is to suggest the revitalization plan of military libraries, on the basis of analysis for the military library status and the results of a survey and interview with soldiers and working staff in the military libraries. To this end, first, it analyzes study trends in the operation and revitalization plan of the military libraries based on the preceding research analysis and investigates and analyzes the operation of the military libraries. Second, it identifies problems in the operation of the military libraries by comparing and analyzing between the operation of domestic military libraries and the best cases as well as the operation situation of the overseas military libraries. Third, it suggests the revitalization plan by holistically analyzing the situation and the best cases of the military libraries while finding out the problems through interviews and questionnaires. According to the analysis, first, it is necessary to expand the number of exclusive personnel with librarian qualifications and prepare standards for the placement of librarians. Second, it is necessary to develop online education to provide regular operation education for the personnel of the military libraries. Third, it is necessary to develop common manuals for working staff. Fourth, it is necessary to prepare the plan to expand the preference books of soldiers to increase reading and usage rate of the military libraries. Fifth, it is necessary to construct library space in the form of a book cafe for soldiers' knowledge development and relaxation and to locate the library in a highly accessible place. Lastly, it needs to develop the application of the military library and should lead to high interest in libraries by letting soldiers read books and post book reviews on it after work.

The purpose of this study is to provide the future development of the PRC Marine Corps by analyzing the changing functions via its historical development. The PRCMC is an elite regular military forces and was established by the Central Military Commission(China) in 1953 in order to project the national military power toward the enemy's territory by overcoming maritime obstacles such as seas and lakes. The PRCMC is relatively smaller personnel strength compared with the whole size of the PRC military forces. Thus its functions were limited in the areas of amphibious and land operations, island and land defense against Taiwan before the PRC pursues expanding policy toward outside. However, in the 2000s, China pursues its policy for obtaining absolute national interest so that its functions are rapidly enlarged into defense of the forward naval bases, and those for evolving its power toward outside according to not only the island territorial dispute with Japan, but also Xi Jinping's active expanding policy what we call 'the one belt and one road'. So its personnel strength is slowly increased. If the increasement of the PRC Navy and Marine Corps would develop into the level of which they can contain the status and influence of the US military power in Asia-Pacific area, it is possible that the security environment of the North-east Asia including the Korean peninsula will be fluctuated. Consequently, the ROK also needs to reevaluate the functions and the size of the joint strength of the ROK Navy and Marine Corps considering the transition of the changing security environment.

The purpose of this study is to analyze the domestic and overseas laws and regulators' decisions related to zero-rating (ZR) practices through a comparative approach and to support development of the ex-post regulation. Although most countries are adopting ex-post regulatory approaches toward the globally increasing ZR practices, there is no uniform standards or an approach to consider when deciding whether to allow mobile ISPs' zero-rating practices in the market. However, in recent years, some countries have been improving their policy transparency with respect to ZR through enacting and amending relevant laws as well as making trial decisions. The comparative analysis shows that each country investigates restriction of the user choice and ISPs' adherence to the obligation of non-discrimination in order to judge whether the user benefits are damaged by the ZR practices. It also investigates ISP-CP's market positioning and ISP's vertical integration for profit squeeze to find out whether they harm fair competition with ZR practices in the mobile ecosystem. Based on the results of the comparative analysis, we suggest the desirable ZR regulatory directions under the domestic legislative status.

South Korea has recently emerged as one of the leading countries conducting clinical trials. Seoul, for instance, is now ranked at the top of the list among the cities in the world. This paper examines the rapid growth of research involving human subjects in Korea, not just from the economic perspective (e.g., the growth of global pharmaceutical markets and the subsequent increase in the demand for clinical trials), but from the policy perspective (e.g., the government?s drive to support and promote this field as a new industry). The industrialization of clinical trials in Korea has manifested itself in the rise of international Contract Research Organizations (CRO) doing their business in Korea. They are, figuratively speaking, invited to Korea by the government. This paper intends to uncover and discuss the bioethical issues concerning research on human subjects, the issues that tend to be set aside merely as procedural ones like ??workable documents??. To this end, it investigates the practice of clinical trials by collecting hitherto unherad voices from patient-volunteers, physician-researchers, CRO employees, and government officials. This paper also explores the themes of ??ethical variability?? and ??biocapital?? in order to compare and constrast the case in Korea with those in other countries.
