There are many type vehicles in army. They are jeep and truck by basic type. Recently many countries are developing new conceptual military vehicles. And they try for export of those military vehicles to another countries. Also Korea Army is developing military tactical and combat vehicles, and considering various necessary factors for export. But as easing the cold war system tension and reducing of defense budget, decrease in quantity of military vehicles. We think this trend is accelerative. Therefore Government(Military) and defense industry make every effort to increasing sales and productions. In this study, I'll inquire '2013~2017 basic plan for defense industry promotion' for strengthen the power of international competitiveness, and then suggest the increasing method for productions of military vehicles.

Patent information, which is generated under a specific, objective rule for a prolonged period of time, has the properties of technology, right, and management. Because of these characteristics of patents, patent analysis is used to identify R&D capacities and performances, and management strategies of a given nation or enterprise. In this paper, we analyze LTE essential patents which are key IPRs for implementing standardized LTE technology and major weapons in a global patent war. Also, we discuss the status of standard patent data, main applicants and standardization trends based on declared in ETSI standard patents. Especially, we analyzed 15,073 patents data which are possible to analyze patent information.

Globally, it is estimated that the number of people living outside of their country of origin reached 281 million in 2020. The primary drive of those migrants when migrating voluntarily is work to increase their income and provide for their families left behind in their home countries. Those who migrate immediately seek means of income to sustain themselves through a perilous process as currently evidenced in the war in Ukraine and not too long ago in Syria and Venezuela. Unfortunately, migrant workers are globally known to predominantly be working in "4-D jobs"- dirty, dangerous, and difficult and discriminatory; the fourth D was recently added to acknowledge the discriminatory aspect and other social determinants of health migrant workers face in their host country while exposed to precarious work. Consequently, migrant workers are at considerable risk of work-related illnesses and injury but their health needs are critically overlooked in research and policy. Recognizing the UN Universal Declaration of Human Rights "Everyone has the right to work, to free choice of employment, to just and favourable conditions of work and to protection against unemployment", we cannot consider any human life - thus, the life of migrant workers - as dispensable through a structural discriminatory process that undervalues their occupational safety and health, livelihood and the contribution these workers bring to their host countries. This was seen during the preparation for the upcoming world cup in Qatar where migrant workers were exposed to a multiplicity of serious hazards including deadly heat hazards.

The chemical warfare agents (CWAs) have been developed for offensive or defensive purposes and used as chemical weapons in war and terrorism. The CWAs are exposed to the natural environment, transported through the water system and then eventually contaminate soil and groundwater. Therefore, effective decontamination technology to remediate CWAs are needed. The CWAs are extremely dangerous and prodution is strictly prohibited, therefore, it is difficult to use CWAs even in experimental purpose. In this study, 2,4-dichlorophenoxyacetic acid (2,4-D) was chosen as a model representative CWA because it is a simulant of anti-plant CWAs and one of the major component of agent orange. The optimum degradation conditions such as oxidant:activator ratio were determined. The effects of hydroxylamine and chelating agents such as citric acid (CA), oxalic acid (OA), malic acid (MA), and EDTA addition to increase Fe2+ activation were also investigated. Scavenger experiments using tert-butyl alcohol (TBA) and ethanol confirmed that although both sulfate (SO4•-) and hydroxyl radical (•OH) existed in Fe2+-persulfate system, sulfate radical was the predominant radical. To promote the Fe2+ activator effect, the effect of hydroxylamine as a reducing agent was investigated. In chelating agents assisted Fe2+-persulfate oxidation, the addition of 2 mM of CA and MA enhanced 2,4-D degradation. In contrast, EDTA and OA inhibited the 2,4-D removal due to steric hindrance effect.

Based on the sentence "The number of my family member and relatives reached around 200, but since the first year of Geonan(建安) era, two thirds of them died and seven out of ten died of cold damage in less than ten years" in Sanghanjapbyeongron(Treatise on Cold Damage and Miscellaneous Diseases), which is allegedly known to be written by Jangnunggyeong(張仲景), we analyzed the sentence by three factors of time, location and people. These factors are used in the investigation of the disease outbreak, and through this analysis, following conclusions were made. 1. Approximate 10 year crude mortality rate since A.D 196(the first yea of Geonan era) in Jangsa(長沙) province was 67 out of 100 in the population. Approximate 10 year disease-specific mortality rate of cold damage since A.D 196(the first yea of Geonan era) in Jangsa(長沙) province was 47 out of 100 in the population. Regardless of age, gender or other demographic variables, approximate 10 year proportionate mortality ratio since A.D 196(the first yea of Geonan era) in Jangsa province was 70.2%, which lead to the assumption that 70% of death is cold-damage related. 2. Increased disease-specific mortality rate by cold damage in Jangsa(長沙) province for about 10 years since A.D 196(the first yea of Geonan era), and followed increased crude mortality rate in the population, threatened the stability of nation or local government. This is due to the repeated war in late Han Dynasty with political chaos and repeated flood caused by geographical disadvantage in Jangsa province.

The 3D animation is designed to announce the sacrifices of soldiers who sacrificed their lives to protect the country in the middle of the vast ocean and to commemorate their souls, and contains tense moments during the battle through 3D objects and slow motion. In this paper, I examined the use of slow motion using characters and sculptures in the video and the characteristics of commemorative sculptures commemorating the war, and described in detail the animation process using slow motion and sculpture objects expressed in . I hope this study will be help to animation and video producers who want to produce slow motion animation using sculptures in the future.

The recent trend in the war fields on the globe may be characterized by the network-centric warfare, which would, in turn, make the concept of weapon systems be changed. To this end, the concept of system of systems (SoS) has been introduced in literature. An SoS is a collection of multiple systems, each of which is an independent system and can be interoperable with each other. Thus, in defense domain each SoS is a big weapon system as a whole operated in actual environment and each element of it is also an independent smaller weapon system, but they should be interoperable via network among each other. The safety results studied for each elementary system alone may not be fully applicable to the whole SoS. As such, the objective of this paper is to study how to make the SoS safety requirements be distributed down over the interoperable elementary systems. Since handling the interoperability requires a technique of systems architecture, a standard method called the DoD Architectural Framework (DoDAF) has been used here to derive a solution. Using DoDAF, the safety requirements were first analyzed in the operability environment. The results were then studied to be included in an integrated model of both the systems design and safety processes. A further study of present paper would facilitate ensuring safety in the development of SoS weapon systems in practice.

Young Tolstoy, when he was an already well-known writer, accomplished his first overseas travel in 1857, which gave him imaginable opportunities to compare his country's social strata with others such as serfdom, monarchical Russia and industrial and capital Europe. The present story is, indeed, the work which is influenced by those experiences by young Tolstoy during his first journey into Europe. Written in the form of booklet-like-small-piece, rather than an artistic work, the text presents the writer's severe criticism on the world of nature and civilization. Close to the nature itself, narod are those common people for Tolstoy, and they represent love, while the nature creates a necessity to love, hope and bottomless happiness of life. On the contrary, the civilized or civilization itself is considered artificial, willy, reasonal, and erotic congruity among people. For the writer, the most unsafe and ugly, seamy side of the westernized society is a lack of necessity to unify people to people. Though in its early embryonic stage, young Tolstoy's worldview is reflected in this work, especially his sharp tongue on the western people and their society is also detected when the write imposes his message under the mask of a gypsy singer. In addition, the narrator who seems an obvious Tolstoy's mouthpiece delivers his own ideas and impression on the western world, history, art, and literature. For this very reason, the present work contains numerous signs from which the reader is able to interpret, understand, and figure out what young Tolstoy imposes for his work.

Preservation processing for two combat boots was executed through application of 3-dimensional digital technology and with use of preservation materials providing outstanding reversibility and stability. The aim of this was to establish a method to preserve the relics of fallen Korean War soldiers that had been excavated by the soldiers remains excavation corps of the Ministry of National Defense. It was possible to estimate the foot size of the soldiers who would have worn the combat boots via 3-dimensional digital scanning and modeling of the boots. In this process, the original form of the combat boots was restored through the use of 3D-printed structures. The original form was restored through a process of removing contaminants from the excavated relics and performing a conditioning treatment, and through use of an antique-color treatment after bonding and filling in the sections that had been ripped or deteriorated. Following the aforementioned preservation processes, it was possible to confirm that both of the combat boots had soles and top sections made of rubber, and portions of the top section and ankle section of the boots were made of synthetic rubber. As such, it was confirmed that these were similar to the Shoe Pac(M-1944, 12-inch) winter boots that had been manufactured for the purposes of waterproofing and/or protection against cold, and introduced in 1944. Such results confirmed that it is possible to discover the manufacturing techniques, materials, and uses of relics excavated through application of preservation processing, thereby illustrating the importance of the convergent research of scientific preservation processing and 3-dimensional digital technology.
