This article has an aim to study what kind of housing system our ancestors lived with during the Yi-Dynasty by analyzing the house-plan of upper-class society of that period since the house of lower-class was very insignificant as it has always been while the house of upper-class represented the period. With this study we can clearly see how we ought to go in the right direction toward the development of our Korean genuine housing by renovating and renewing those unreasonable points in our traditional housing system. It is firmly believed that we should-keep our own unique traditional lovely housing system for being destroyed by the whirl-wind of modernization and the demand of rationalism and efficiency-centered idea of the western mind. From this view point we think it is very urgent to see this matter correctly and find out the real way how we should do in order to keep our own good things for ourselves and make them preserved. This essay is divided into three parts as follows : 1. Thoughts on selecting the good housing area. 2. The aspect of housing reflected upon composing the house-plan. 3. The characteristic sentiments reflected upon the interior construction and decoration. We can find several characteristic points in the housing system of the Yi-Dynasty as follows : 1. In Korea, the thought of natural geography (Poongsu-seul), apart fro scientific view, which seems rather superstitious to us, modern young people, has been highly recommended by the people of our country from old days connected with the prosperity of our life. They also neglected about the social circumstances such as, market, transportation, and education, which are now considered as very important. They only put their concern on this natural environment which they called Poongsu. 2. In construction of house-plan, the house was not built for living with reasonable convenience, but for showing prestige of the upper-class people reflecting its social organization under the feudalism of the period. Furthermore, the most of the housework was done actually by those servants and maids of the house, and not the family themselves. The only concern for the upper-class people was to show off their authority, and so this sense of authority was revealed in the housing as well. 3. Both the outside appearance of the house and the interior decoration or the furniture are all very artistic and lovely. They were so refined and beautiful with their delicate taste which truly seem against our modern rationalism and uniformity.

Coronavirus disease 19 (COVID-19) is caused by SARS-CoV-2 (Severe Acute Respiratory SyndromeCoronavirus 2). To date, seven coronaviruses that can infect humans were reported. Among them, infections with four coronavirus strains (HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1) resulted in mild symptoms such as common cold, whereas SARS-CoV and MERS-CoV caused severe symptoms and epidemics in 2002 and 2012, respectively. In the most recent, SARS-CoV-2 was first reported in Wuhan, China in December 2019 and became a notorious cause of the ongoing global pandemics. To diagnose, treat, and prevent COVID-19, the development of rapid and accurate diagnostic tools, specific therapeutic drugs, and safe vaccines essentially are required. In order to develop these powerful tools, it is prerequisite to understand a phenotype, a genotype, and life cycle of SARS-CoV-2. Diagnostic techniques have been developing rapidly around world and many countries take the fast track system to accelerate approval. Approved diagnostic devices are rapidly growing facing to urgent demand to identify carriers. Currently developed commercial diagnostic devices are divided into mainly two categories: molecular assay and serological & immunological assay. Molecular assays begins the reverse transcription step following polymerase chain reaction or isothermal amplification. Immunological assay targets SARS-CoV-2 antigen or anti-SARS-CoV-2 antibody of samples. In this review, we summarize the phenotype, genome structure and gene expression of SARS-CoV-2 and provide the knowledge on various diagnostic techniques for SARS-CoV-2.

Overseas advanced countries are aware of the importance of research equipment and are providing a lot of policy support to revitalize the research equipment industry. However, Korea does not have any law to support policies or related projects to revitalize the research equipment industry. Therefore, there is an urgent need for legislation to support policies and projects for revitalizing research equipment industry. It is considered necessary to establish a separate special law for revitalizing the research equipment industry so that it can gain competitiveness in the global market of the research equipment industry. As we have seen, the necessary articles in the relevant laws should be specified so that various promotion policies can be developed to foster the research equipment industry. In order to promote the development of research equipment industry, there are three essential items to be specified in the law. First is research and development support, second is infrastructure development, and third is business incubation. The following contents should be included in each contents. First of all, "research and development support" includes research and envelopment project promotion and support policy items, research equipment development trends and investment trends, joint research between industry, academia, And research and development support for fusion, hybrid and commercialization. Next, the items to be included in "infrastructure development" should include the establishment of research equipment clusters, related support items, training of professional manpower, and research equipment development base area and institutions. Finally, the items that should be included in "business incubation." include support matters for the development of excellent companies (priority purchase system, etc.), matters related to technology transfer and marketing, matters concerning the protection of intellectual property, And matters for promoting overseas expansion.

Manufacture of fishing vessel is needed the effective material for light, strength, fire and corrosion of water in order to improve durability by high-speed and fishing. These fishing vessel can be divided into FRP and AI alloys fishing vessel. FRP fishing vessel is light and effective for strength but highly ignited and susceptible to heat during the manufacturing ship by-produce noxious component for human. In the case of a scrapped ship, it cause environmental pollution. On the other hand, aluminum is a material in return for FRP and has merit of high-strength and lightness. It's more heat proof and durable than FRP and superior to prevent from corrosion. Al alloys fishing vessel development is rising as an urgent matter. But, al alloy has some defect of bad weldability, welding transformation, cracks and overcost of construction. Therefore this study is to develop the new welding joint shape solving aluminum defects and mechanical behavior. First of all, strength was compared and reviewed by analysis of plate, stiffen plate, new model simplified by using plate theory. On the base of this result, plate and new model of temperature distribution, weld residual stress and strength of tensile, compressive force were compared and reviewed by finite element computer program has been developed to deal with heat conduction and thermal elasto plastic problem. Also, new model is proved application possibility and excellent mechanic by strength comparison is established to tensile testing result.

The purpose of this study was to investigate the degree of awareness of the concept of 'hospice palliative medical care' and decision of 'life-prolonging medical care' by the general public subjects. A survey was conducted on 346 participants and officials who participated in an event held in September 2016. As a result of the research, the subjects' responses results to the life-prolonging medical care decision showed that people with religion wanted natural death compared to people without religion, and had more active attitude toward decisions related to dignity death. Religion is an important factor that can influence perceptions of life and death, believing that afterlife is after death, so it is possible to take a more firm stance on the extension of meaningless life at the last minute. Therefore, in order to stabilize the hospice care and prescription medical decision law to the general public and to improve the quality of the death and the dignity of life, it is necessary to develop awareness through various educational programs in consideration of age, education level. In addition, education and promotion should be strengthened so that the general public can fully understand the knowledge of hospice palliative care and health care and government standardization and policies for hospice personnel and breeding programs will be urgent.

The area of security service has been maintaining the high growth curve annually by improving security consciousness from increase of the income and the progress of public services's level by the accomplishment in the info-communication field, recently the demand for unmanned security system is extended form commercial purposes into public offices and individual's houses. In addition to, the possible distance of offering services is scheduled to magnify. At the period when security company's influence has been becoming significant, the injustice transaction is the serious factor which obstructs the development of security companies. Therefore, it is urgent thing to devise counterplans to extirpate injustice transactions. There are the legalistic approaches of the breakthroughs against injustice transactions. One thing is settling the standard of the judgment and the other is renovating the provision of injustice transactions. Utilizing the principles of the fair competitions and importing self-obedience programs within the range of trade actions which is permitted by law, acted as the system approach. Moreover, there are such three things which can achieve mutual balances as establishing the range of the permitted action toward business corporations, applying spontaneously the fair competition principles and introducing the system of standard agreements. Gong further, this can establish order of security service areas and control them. Besides, it is possible for every organizations to make and operate the system appropriately by importing the self-observance system.

This study investigated the current status and needs of nutrition education to help reduce children's sugars intake, according to the annual budget of the Center for Children's Foodservice Management (CCFM). Through an online survey conducted in October 2015, the 115 CCFMs participated in this survey and they were divided into the following three groups according to the annual project budget: 1~2 million won (${\leq}2M$; n=25), 3~4 million won (3~4 M; n=60), and 5 million and over won (${\geq}5M$; n=30). A total of 8.0% of the ${\leq}2M$ group respondents provided nutrition education on the sugars intake to young children as a main topic, which was significantly lower than those of the 3~4 M(16.7%) and ${\geq}5M$ (16.7%) groups (p<0.05). The most common reasons given for not delivering nutrition education on sugars were "insufficient nutrition education information and materials" for the ${\leq}2M$ (47.1%), and "more urgent nutrition education topics than that" for the 3~4 M (66.7%) and ${\geq}5M$ (50.0%). The percentage of nutrition education on children's sugars intake provided to their parents was low, showing about 8% in the ${\leq}2M$ group, 28.3% in the 3~4 M group and 23.3% in the ${\geq}5M$ group (p<0.05). However, more than 90% of the respondents answered providing nutrition education on sugars intake reduction to children was needed regardless of the annual project budget. The results indicate a great need for the development and dissemination of standardized educational programs about children's sugars intake in order to provide a leveled education program regardless of the project budget, and to solve the difficulties of development and operation of nutrition educational programs due to a lack of budget and human resources of CCFMs with less annual project budget to manage the projects.

Purpose: In order to validate empirically the theoretical model of this study subjects, who were limited in Andong gun, Youngyang gun, Uiseong gun, Bonghwa gun, Chilgok gun, Cheongsong gun according to residence-specified distribution and over aged 65, were focused to the elderly in rural areas with geographical characteristics where they have difficulties in accessibility of dental facilities and dental care. Methods: The collected data were analyzed by the SPSS 19.0 program. First, the frequency analysis was performed for each independent variable and the dependent variable. Second, reliability analysis and correlation analysis were conducted for daily living skills and Biomedical Vigilance. Third, multivariate analysis was performed in terms of and the post-administration management. Fourth, multiple regression analysis was performed to identify the factors affecting the post-management of dentures and the period of using dentures. Results: By results of the multiple regression analysis, the elder the subjects are(${\beta}$ = 0.03), the lower their income activities are(${\beta}$ = -0.18), the smaller their monthly allowances are(${\beta}$ = -0.16), the worse their daily activity skills are(${\beta}$ = -0.12), the more they were mounted their dentures by an unlicensed contractor(${\beta}$ = 0.07), and the more they cost to their dentures(${\beta}$ = 0.14), the longer the period of use dentures are. And the beneficiaries of Basic Livelihood Security(${\beta}$ = -0.14) who got free denture business are shorten the period of using dentures. According to multiple regression analysis for post management of dentures, the independent variables like the health education(${\beta}$ = 0.24), smoking(${\beta}$ = -0.18), periodic oral examination(${\beta}$ = 0.13), dentures mounted by an unlicensed contractor(${\beta}$ = -0.13) are shown statistically significant results. In that study subjects are taking part in health education and non-smokers, they are likely to have more chances to post management for their dentures like periodic oral examination. However the subjects who were weared their denture by an unlicensed contractor get less chance to post management for their dentures. Conclusion: As the elderly who want to wear denture are increasing due to the denture insurance for the elderly, the need for oral health education for the elderly is an urgent request, especially continuos education for the way of use their dentures and follow-up management for the elderly who were already mounted their dentures. And also, the need for more systematic researches is requested for securing objective data.

As a recent cyber attack has a characteristic that is intellectual, advanced, and complicated attack against precise purpose and specified object, it becomes extremely hard to recognize or respond when accidents happen. Since a scale of damage is very large, a corresponding system about this situation is urgent in national aspect. Existing data center or integration security framework of computer lab is evaluated to be a behind system when it corresponds to cyber attack. Therefore, this study suggests a better sophisticated next generation convergence security framework in order to prevent from attacks based on advanced persistent threat. Suggested next generation convergence security framework is designed to have preemptive responses possibly against APT attack consisting of five hierarchical steps in domain security layer, domain connection layer, action visibility layer, action control layer and convergence correspondence layer. In domain connection layer suggests security instruction and direction in domain of administration, physical and technical security. Domain security layer have consistency of status information among security domain. A visibility layer of Intellectual attack action consists of data gathering, comparison, decision, lifespan cycle. Action visibility layer is a layer to control visibility action. Lastly, convergence correspond layer suggests a corresponding system of before and after APT attack. An introduction of suggested next generation convergence security framework will execute a better improved security control about continuous, intellectual security threat.

The twenty-first century was entered and began to show the extent where revegetation of the face of slopes using the native woody plant was nationwide at last. Then, future revegetation of the face of slopes was considered on the basis of them in order to attempt the development of this direction, while the recognition for fundamental matter of the revegetation and revegetation of the regional inhabitant was arranged this time. The regional inhabitant sufficiently understood the necessity of the revegetation, and the method using the native woody plant had sufficiently been recognized, and the high evaluation was given in the method. In the other, the major inhabitant questioned it for introducing the exotic species. It was proposed that the utilization of native weeds should be advanced by the pursuit of many facets of the revegetation of the face of the slopes based on these in future in the place where the introduction of the native woody plant is difficult. And, the method for stretching the wire netting for the face of slopes indicated the necessity of the urgent review, because the artificial disaster might be caused. As a conclusion, the goal of the revegetation of the face of slopes confirmed that it was ecologically stable short-terminable face of slopes physically and connects it with the medium and long term for improvement and improvement of global environment, and it indicated the importance of the revegetation of the face of slopes.
