The military is driving innovative changes such as AI, cloud computing, and drone operation through the Fourth Industrial Revolution. It is expected that such changes will lead to a rapid increase in the demand for information exchange requirements, reaching all lower-ranking soldiers, as networking based on IoT occurs. The flow of such information must ensure efficient information distribution through various infrastructures such as ground networks, stationary satellites, and low-earth orbit small communication satellites, and the demand for information exchange that is distributed through them must be appropriately dispersed. In this study, we redefined the DSCP, which is closely related to QoS (Quality of Service) in information dissemination, into 11 categories and performed research to map each cluster group identified by cluster analysis to the defense "information exchange requirement list" on a one-to-one basis. The purpose of the research is to ensure efficient information dissemination within a multi-layer integrated network (ground network, stationary satellite network, low-earth orbit small communication satellite network) with limited bandwidth by re-establishing QoS policies that prioritize important information exchange requirements so that they are routed in priority. In this paper, we evaluated how well the information exchange requirement lists classified by cluster analysis were assigned to DSCP through M&S, and confirmed that reclassifying DSCP can lead to more efficient information distribution in a network environment with limited bandwidth.

This study links the concept and implications of the anthropocene to the humanistic functionalism of Scandinavian design. Since the Industrial Revolution, the direction of modern design has been centered on the standardization of mechanical products and functionalism aimed at standardization. This is based on the human-centered dual idea of human and nature. But Scandinavian countries have developed humanistic functionalist designs, with exceptions emphasizing human organic relationships to nature instead of dual thinking. This is believed to be in line with the anthropocene discourse, which envisions the emergence of a new level of humanity and the regeneration of the natural environment under the banner of equality for all species on Earth. In this paper, the discussion was embodied in a way that combines the wide range of anthropocene discourses with the major issues of posthuman and postnature, which are the latest human and natural views. And we have selected and analyzed examples of modern Scandinavian designs focused on the circulatory potential of materials, and have sought the direction of trends suitable for the anthropocene era.

This study is to discuss the content of Posangkimun on the whole and to report the understanding of Seokgok Lee Gyujoon on western civilization. Through the overall analysis of Posangkimun, it is found the following facts: 1. Posangkimun aroused interest of academic circles as it covered theories of western civilization. Most of the introduction to western civilization contained in the book is related to astronomy and geography. Seokgok criticized all the western theories on revolution of the earth, astronomy, continents and oceans on the ground that these theories were not congruous with the teaching of the Oriental sages. 2. Seokgok found the reasons why the West had led the East from 'nationalism' of the West. The nationalism mentioned here were more similar to 'democracy' in modern sense, or rather 'democratism'. What is specially noteworthy is that he did not find the reasons of western advancement from the spiritual issues not from the machine civilization. In this way, Seokgok could avoid the fallacy of throwing away traditional ideas to concentrate in western machine civilization. 3. The content of Posangkimun shows that Seokgok was a person with a very conservative view. Notwithstanding his inclination, he had good knowledge about western theories, most of which were gathered from newspapers and magazines at that time. It means that newspapers and magazines should be treated with more importance when studying Korean intellectuals in late Joseon period or during the time of Japanese forced occupation.

The Sun's ray is composed of Infrared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(Far infrared; 60%), IR(Infrared; 20%), and UV(Ultra Violet; 20%). Human beings has utilized FIR already from time immemorial. Hershel found out Infrared for the first time. in the Industrial Revolution the Infrared and FIR had been begun to use making products. In these days, with contemporary science FIR would be begun to clear up the implication in the human body and organic compound. IR classified by wavelength three parts NlR, MIR, FIR. There is FIR which is radiated from healthy human body the wave length is 8-l4m. The human body is composed of proteins which get easily changed by a thermal factor (about 42 $^{\circ}$C over). FIR with low temperature can deeply penetrate on the human body composed things without troublesomes, since FIR has effectively operated on the human body at low temperature (35-40 $^{\circ}$C). When FlR penetrated on the human body. it would inhibit the abnormal genes and cells expression, and then information of DNA and RNA would be reexpressed for arranging DNA and RNA abnormal state. As FlR's receptors in the body, it could be presumed that N-glycosyl linkage of purine and deoxyribose, RNA splicing process, and Heat shock protein. To take the FIR which was a optimized wavewlength and strength, at first, we induced the characteristic algorithm and the computerized programing. Then we formed that the formular of optimized FIR with physical, mathematical logic and theory. especially, Plank, Kirchhoff, Wien, Stefan-Boltzmann's logic and law. In the long run, the formular was induced with integration mathematical, since we had to know the molecular wavelength. Based on the induced formular as above, we programmed the optimized FlR radiating computerized program. In this research, we designed the eletronic circuit f3r interfacing with human body to diagnosis and treatment with FIR sensor which radiated FIR wavelength optimized.

A new era with the $4^{th}$ Industrial Revolution certainly brings new opportunities for human to explore human's activities outside of the Earth. After the Apollo program, exploration for lunar resources and establishment of lunar base seem to be in reality. This could be due to new findings by the LCROSS and LRO proving the advanced scientific development and new scientific results about the moon from Asian countries including China with Chang'E missions. It is expected that fossil fuels will be in shortage in the near future and at this time, Helium-3 could be an energy resource as a replacement of the fossil fuels. At present it is well known that countries like Russia, USA, and Europe will continue to investigate on lunar exploration especially with landers toward future human activities on the moon to establish a lunar base. With this point of view, it is important for human to understand lunar resources and prepare for prospective utilization of lunar resources. This review paper considers on a point of view in both lunar resource exploration and establishment of lunar base.

Since Industrial Revolution, the sudden industrialization and population explosion have brought about a serious environmental pollution on the air of the earth, the quality of water and the soil, and the greenhouse effect by the destruction of the ozone layer and the greenhouse gas, the organism diversity decline, the desertification by the ruining of woods and the overall global environmental pollution such as the contamination of the ocean and rivers have been come to the front. So the new recognition on the environment is being spreaded in construction business and the efforts for certification acquisition of ISO 14000 being followed by ISO 9000 are progressing, Accordingly, with an example of H Company where integration system is built so that it can minimize the efforts and cost at the construction of the management system, operation and management after the fact, this paper shall suggest the practical scheme of 3 steps through a study to integrate both existing quality management system and new environmental management system. As the integration system of the quality and environment which is constructed by this method is executed, the number of the established and managed document is cut by about a third and so the disorder to encounter between these documents is prevented and unnecessary efforts is reduced in constructing a system, consequently the efficiency of the system is accomplished. Also as the dualization of quality management system and environmental management system additionally needs more men and money after certification acquisition, the non-construction of the integration system may give rise to a cause to aggravate the burden of the company and hereafter when a new system is imported, it may be very difficult to integrate the system. This system integration enables a efficient and effective system to be constructed , operated , and managed after the fact.

In the existing education using the globe. teaching contents are very simple and the relationship among learning units lacks a little bit because teaching materials are composed individually with the globe. Therefore, in this study, we developed the education glove system based on multimedia that is closely connected with teaching materials and the globe. This system is composed of the globe device and the learning software based on computer control. The globe device rotates itself on its axis as the solar center, and provides more efficient and visual education environment to students through the link between computer and the globe. The learning software provides the multimedia contents such as parallax, climate, culture, and education information about each country, and this software also can simulate the revolution of the earth around the sun. The globe device can be operated in off-line without the computer link. This system was developed by the industry cooperation and was displayed in the principal exhibitions. We have obtained positive results through the exhibitions and will promote the product in the future.

To discuss whether we have credible estimations about historical surface temperature evolution since industrial revolution or not, present study investigates consistencies and differences of averaged surface air temperature since 1900 between the multiple data sources: Hadley Center Climate Research Unit (HadCRU4) surface air temperature data, ECMWF 20 Century Reanalysis data (ERA20CR), and NCEP 20 Century Reanalysis data (NCEP20CR). Averaged surface temperatures are obtained for the global, polar (90S~60S, 60N~0N), midlatitude (60S~30S, 30N~60N), tropical (30S~30N) region, separately. From the analysis, we show that: 1) spatio-temporal inhomogenity and scarcity of HadCRU4 data are not major obstacles in the reliable estimation of global surface air temperature. 2) Globally averaged temperature variability is largely contributed by those of tropical and midlatitude, which occupy more than 70% of earth surface in area. 3) Both data show consistent temperature variability in tropical region. 4) ERA20CR does not capture warm period over Arctic region in early 1900s, which is obvious feature in HadCRU4 data. Discrepancies among datasets suggest that high-level caution is needed especially in the interpretation of large Arctic warming in the early 1900s, which is often regarded as a natural variability in the Arctic region.
