In project projects where various factors arise, the construction company's initial establishment of a reasonable process plan reduces various variables and potential risks. In order to create a densely written initial process plan, it is necessary to compare the economic feasibility of time and money by reflecting Slack time. Through this, site managers can lead a successful project based on reasonable and stable construction.

The purpose of this study is to explore the necessity and possibility of establishing a research institute for local educational autonomy where the importance and necessity of institution establishment and operation are increasing with the decentralization and educational autonomy. The necessity of establishing a local educational autonomous research institute was examined in terms of both external and internal necessities, and the possibility of establishment in terms of the form of establishment, financial resources, and legal basis. In order to effectively cope with common issues by leading the nation's educational autonomy policy and legal agenda, and to support regional policy research and development by linking and cooperating with regional educational policy research institutes, local educational autonomous research institutes are established. This is an urgent point. Considering the publicity, professionalism, economic feasibility, and stability of specialized research institutes, the form of foundation corporation seems to be appropriate, and, like the case of specialized research institutes in general local autonomy, legal grounds for the establishment of special law should be prepared. In the future, it is necessary to conduct collaborative discussions and academic discussions with the Ministry of Education and the National Council for Superintendents of Education.

As the cosmetics beauty industry grows into a key next-generation industry, the establishment of an industrialization center is needed, but failure to verify the adequacy and feasibility of the investment could lead to financial burdens. In this study, the project costs and facilities of an industrial center are reviewed to analyze its economic feasibility based on the cost estimates, revenue estimates, estimated profit or loss calculations, and estimated operating cash flows. The profit estimation criteria were analyzed by applying 90 per cent of expected orders for research projects (24 billion won) and 12 per cent of rental rates for testing equipment (4.5 billion won for construction), and the benefit/cost ratio is higher than 1.02 per cent and the net present value is higher than '0' won, and the internal rate of return is also more than 5.06 per cent for all three analytical methods. Therefore, in order for the construction of a cosmetics beauty industrialization center to be economically feasible, it is necessary to maintain research project orders of more than 90 percent and return on equipment rent of more than 12 percent, and a strategic approach is needed to diversify business profits.

Due to COVID-19, the importance of public medical facilities, especially hospitals specializing in infectious diseases, is rising. Despite the government's strong will, the establishment of public medical facilities and infectious disease hospitals has not been properly established. This is because the overall system related to the construction of public medical facilities does not sufficiently reflect social and economic changes and the trend of the times. The purpose of this study is to derive limitations and problems related to the guidelines for preliminary feasibility studies of public medical facilities and to present alternatives. This study proposes 'Option Value' as an alternative. Since the option value is a willingness to pay for an uncertain situation, it is theoretically reasonable and reasonable to reflect it as an additional benefit. Normally, the value of existence is not seen, but the system that is seen in a crisis is in the 'medical and health'. Therefore, it is necessary to find a system that is invisible even in the feasibility evaluation in the medical and health, and constantly improve and develop a methodology that can estimate changes in the welfare of citizens within the system. I expect this study to play a role as a catalyst.

This study examined the feasibility on the construction of a wood industrialization service center for a wood industry cluster establishment in Jeollanam-do. Construction of the wood industrialization service center is based on a discount rate of 3.5%, an investment period of 4 years, a business operations period of 16 years and an investment cost of 24600 million won; the total amount of the net present value, the cost-benefit ratio and the internal rate of return were assumed to be 2.579 million won, 2.51%, and 10.1%, respectively. In addition, the production inducement coefficient, the induced production effect, the income-induced coefficient, the income inducement effect, the employment inducement coefficient, and the employment inducement effect were estimated 1.4345, 35287 million won, 0.1655, 4000.7 million won, and 0.4665, 1,145 people, in the effects of the wood related industries using the multi-regional input-output model, respectively. Financial independence of operating income to cover its own costs incurred in accordance with the operating project might be practicable.

Industrial security research has shown a rapid increase over the past decade. With the establishment of the Korean Association for Industrial Security in 2008 and the establishment of the departments of industrial security in recent years, academic interests and research on industrial security are also spreading at a rapid pace. Although academic interest and research have grown in quantitative terms, research on theoretical fields that are the basis of academic systematization is extremely limited. There is a focus on the issue of specific issues and practical solutions without worrying about the theoretical basis including conceptualization. Therefore, in most studies, the concept of industrial security remains at the level of accepting the concept applied in the previous research. Most industrial security research focuses on the specific topic of 'industrial technology protection' because it considers the concept of industrial security to be reduced to industrial technology protection. Although industrial security is composed of a wide range of fields, recognizing a specific field as an entirety of industrial security appears to be a serious problem. As a result, the concept of industrial security in industrial security research is being used ambiguously, incorrectly, and conveniently. It is necessary to accurately and recognize the concept of industrial security based on logical clarity and empirical feasibility.

To test the feasibility of using chlorophyll ${\alpha}$ fluorescence to assess the establishment success of seagrass transplants, photosynthetic characteristics of eelgrass Zostera marina transplants were measured using a Diving-pulsed amplitude modulation fluorometer in Jindong Bay on the southern coast of Korea. Maximum quantum yield ($F_v/F_m$), photosynthetic efficiency ($\alpha$), saturating irradiance ($E_k$) and maximum electron transport rate ($ETR_{max}$) of transplants and reference plants in a nearby transplant site were measured using the fluorometer for 5 months. Additionally, shoot morphology, individual shoot weight and productivity of transplants and reference plants were also monitored. Shoot height, leaf weight and productivity of transplants were significantly reduced during the first two or three months after transplantation compared to those of reference plants, and then increased to the levels of reference plants Characteristics of chlorophyll a fluorescence, including $F_v/F_m$, $\alpha$, $E_k$ and $ETR_{max}$ of transplants were also significantly reduced in the initial period, but recovered slightly sooner than shoot morphology or leaf productivity. These results indicated that after transplantation, Z. marina transplant photosynthesis recovered faster than shoot morphology, biomass or productivity. Thus, chlorophyll a fluorescence can be used as an indicator for early assessment of the status of eelgrass transplants without destructive sampling.

The amount of spent fuel from nuclear power plants has been increasing. An effective management plan of the spent fuel becomes a critical issue, because the storage capacity of each plant will reach its storage limit in a few years. The volume of high toxic spent fuel can be reduced through a fuel processing. Advanced Fuel Cycle (AFC) system is considered to be one of the options to reduce the toxicity and volume of the spent fuel. It is necessary to set up a test facility to demonstrate the feasibility of the process at the engineering scale. The objective of the work is a development of the safety evaluation technology for the AFC system. The evaluation technology of the AFC structural integrity and processes were surveyed and reviewed. Key evaluation parameters for the main processes such as electrolytic reduction, electrorefining, and electrowinning were obtained. The survey results may be used for the establishment of the AFC regulatory licensing procedure. The establishment of the licensing criteria minimizes the trials and errors of the AFC facility design. Issues taken from the survey on the regulatory procedure and design safety features for the AFC facility provide a chance to resolve potential issues in advance.

The security of wireless sensor networks is a challenging research area where the resources constraints are a bottleneck for any successful security design. Due to their computational feasibility, symmetric key algorithms that require key pre-distribution are more desirable for use in these networks. In the pre-distribution scheme, keys or keying materials are assigned to each node prior deployment to guarantee a secure communication within the entire network. Though several works are introduced on this issue, yet the connectivity and resiliency are imperfectly handled. In this paper, we revisit the grid based key pre-distribution scheme aiming to improve the connectivity, introduce a higher resiliency level, simplify the logic of key establishment and maintain same level of used of resources usage. The core of our modification relies on introducing the novel plat-based polynomial assignment and key establishment mechanism. To demonstrate the advantageous properties of our scheme over the revisited one, details of consumed resources, resulting connectivity, security and comparisons with relevant works are introduced.
