In study, various notions regarding historic landscapes and rehabilitation were first investigated, and efficient rehabilitation schemes on modem historic landscapes were analyzed. On the basis of these theological analyses, an underlying scheme on the rehabilitation of modern historic landscapes was drawn up for '40 Stair Cultural Street' in Jung-gu, Busan City. Rehabilitating historic landscapes not only expresses a positive method to preserving sites and relics of heritage, but also an idea of preservation and rehabilitation based on interpretations from a historical perspective of value in this present day. Its significance is, therefore, to construct an ideal urban landscape in which the past, present and future can coexist. The rehabilitation of historic landscapes will become a psychological pillar to the people living in cities and will be able to lead the various types of urban activities as effective landmarks creating accessibility and representing perpetuity, as rehabilitated landscapes last through the passage of time. In addition, since historic and cultural landscape resources significantly represent regional identities and cultural characteristics that are protected and maintained, they may result in the succession of time and space in regional and urban historical culture and contribute to improving local images and impressions, allowing citizens and tourists to experience many diverse historic and cultural environments. The underlying scheme on the development of '40 Stair Cultural Street' in the study has been drawn up with a focus on the rehabilitation of modern historic value drawn out of the 40 stairs. The area around the 40 stairs, which was shaped as a stronghold of refugees who fled for safety during the Korean War, has changed as dramatically as people can no longer get a feel of the circumstances of that period. Local historians and residents, however, still share the joys and sorrows of refugee life as sad memories. Based on the historical fact, landscape planting, street furniture, outdoor color schemes & signage, traffic systems, symbolic 3-D models and pavement designs are underway.
March 19, 1999, the renovation qf the runway of the Bo-Fai ai1field in Hua Hin, Prachubk-erikhan, Thailand, unearthed chemicals which were left over from the project "anch Hand Operation" held during the Vietnam war era. The chemical mixtures were analyzed by the US EPA, the Department oj Medical Sciences (DMSc), Ministry oj Public Health (MoPH) and the Pollution Control Department (PCD), the Ministry oj Science Technology and Environment (MOSTE) of Thailand, The samples were found to contain several defoliants used in the operation. They were 2,4-D, 2,4,5-T, Dicamba, Cocydelic acid, and Dioxins. Due to the complexity of the issue, the multiplicity of possible health effects, and the socio-economic implications for imports and exports, the Thai Society of Toxicology submitted a proposal to request World Health Organization (WHO), Geneva. The assistance is for the area of chemical safety and called for immediate action to explore the magnitude qf risk involved with Dioxins. In this paper we present our approach to health risk assessment which takes into an account the epidemiological studies of high-risk group exposed to the Ranch Hand operation. Dioxins are endocrine disruption chemicals which public concerns are developed due to presumption that a hazard exists (www.eva.gov/dioxins/html) for which current methodologies are deemed insufficient. The recent concepts of how oxidative stress toxicants may affect health end points and biomarkers of exposure of exposed individuals are discussed. While research activities are undergoing, The Thai Society of Toxicology do not anticipate significant risk to local residents and the environment due to our concurrence with opinion from the international experts invited by the World Health Organization proposed to the local experts at a workshop in Bangkok.n Bangkok.
With the possibility of wireless control of the aircraft by Nicola Tesla, Unmanned Aerial Vehicle(UAV) was mainly used for military and defense purposes with the rapid development through World War I and II. As civilian applications of unmanned aerial vehicles have expanded, they have been used with various services, and attempts have been made to control various environmental changes and risk factors of unmanned aerial vehicles. However, GPS spoofing, Jamming attack and security accidents are occurring due to the communication in the unmaned aerial vehicle system or the security vulnerability of the unmanned aerial vehicle itself. In order to secure introduction of Unmanned aerial vehicle, South Korea has established Unmanned Aerial Vehicle verification system called Airworthiness Certification. However, the existing cerfication system is more focused on test flight, design and structure's safety and reliability. In this paper, we propose a unmanned aerial vehicle system model and propose security functional requirements on unmanned aerial vehicle system in the corresponding system model for secure-introduction of Unmanned Aerial Vehicle. We suggest the development direction of verification technology. From this proposal, future development directions of evaluation and verification technology of Unmanned Aerial Vehicle will be presented.
The Mahan's seapower theory has been the basis of US Navy to date as it can enjoy the supremacy status in all of the seas of the world. His theory is very straightforward. A nation can be a great country in the world just through the use of maritime commerce that could be protected by a strong and powerful navy. Mahan's theory on seapower was substantiated in the Spanish-American War with respect to how important the naval power is. The best thing to make US a great nation was to make sure that flow of international trade is smooth, and the unhindered trade could be made possible only by the destruction of enemy's fleet that may obstruct the SLOCs. That's why Mahan insisted that a strong navy was needed and a decisive battle by the navy's fleet at sea should be encouraged as a way of ensuring the safety of the SLOCs. The newly-arrived Trump administration seems to be in line with the Mahan's theory seapower in its policy on naval forces structure. It is expected that US will continue to support the Pivot to Asia policy that has been adopted by the previous administration through an increase in its naval fleet forces. The number of US navy ships will be 355 in 2030, rendering it much more powerful navy than before. The catch phrase "3rd Fleet Forward" proposed by the president Trump indicates that two carrier strike groups will be present in the Asia Pacific region, being able to make the confrontation between US and China more tense than before. The presence of the US naval forces in the area may function as some sort of pressure against China that Trump insisted had been responsible for the closure of 60,000 factories and the loss of 3,000,000 jobs in the United States.
The Han River is divided into North and South Korea by NLL(Northern Limit Line) and its area has been blocked by CCL(Civil Control Line) since the Korean War in 1950. Satellite remote sensing, therefore, is uniquely suited to monitoring bar transformation in the region. In river with bar, the characteristics of its physical conditions have a close relationship with bar morphology. In this paper, a monitoring approach of bar transformation in the Han River Estuary is presented using RADARSAT/SAR images from 2000 to 2005 and spatial patterns of bar morphology are presented. It could be said that in the estuary vegetated area and natural levees are developed well, but bars are shifted after an event like a flood. It is also showed that suspended solids such as silt transported through the estuary could contribute highly to a sedimentation environment around Incheon.
While the United States and other Western states are in trouble with COVID-19 crisis, China is continuing its aggressive ocean expansion with its Gray-zone strategy. The Gray-zone strategy, which China uses around the South China Sea, refers to a strategy that promotes a change in international politics by creating an unclear state, neither war or peace. China, which is trying to expand its influence across East Asia, will also try to project a Gray zone strategy on the Korean Peninsula. The possible scenarios are as follows: 1) South Korea is accidentally involved in a dispute in the South China Sea, 2) Military conflicts between South Korea and China is caused by illegal fishing of Chinese boats in Yellow Sea, 3) China tries to interfere with Socotra Rock, 4) Unlikely, but possible in the future that China induce the military conflicts between Korea and Japan on the Dokdo issue. In order to cope with these scenarios, Korea should prepare the following measures from a long-term perspective: the creation of an Asian maritime safety fleet, the integ rated operation of the navy and the coast guard in the framework of the national fleet, and strengthening the conflict control system for China's provocations.

The global crisis caused by the coronavirus disease 2019 (COVID-19) led to the most significant economic loss and human deaths after World War II. The pathogen causing this disease is a novel virus called the severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). As of December 2020, there have been 80.2 million confirmed patients, and the mortality rate is known as 2.16% globally. A strategy to protect a host from SARS-CoV-2 is by suppressing intracellular viral replication or preventing viral entry. We focused on the spike glycoprotein that is responsible for the entry of SARS-CoV-2 into the host cell. Recently, the US Food and Drug Administration/EU Medicines Agency authorized a vaccine and antibody to treat COVID-19 patients by emergency use approval in the absence of long-term clinical trials. Both commercial and academic efforts to develop preventive and therapeutic agents continue all over the world. In this review, we present a perspective on current reports about the spike glycoprotein of SARS-CoV-2 as a therapeutic target.

Korean seafarers have played a key role throughout the country's history and economic development. They have been a major source of foreign remittance into the nation as well as a pivotal sector in emergency logistics during war times. However, the current number of Korean seafarers in decreasing due to low job attractiveness and retention rate onboard. This is a major problem for the national and international shipping industry as youth seem not to be interested in working onboard for long periods of time. The purpose of this study is to 1) determine what the public opinion about seafarers in Korea is and 2) find out what factors mostly stand out in the public opinion about seafarers profession. The paper suggests that three main types of opinion groups emerged. The first type is labeled as 'high risk, high workload and high stress' as respondents recognized a high possibility of accident onboard and, at the same time, acknowledged that seafarers can be fatigued and stressed. The second type was named as 'Dangerous, Dirty, Difficult', as seafarers' image was mainly associated to fishing vessels and not to merchant and passenger ships. The third type recognized that the social position of the seafarers was low due to 'low social recognition'. The study suggests that all three types have a negative image of seafarers' job. Based on the results of this study, it is necessary to establish various policies and marketing tools to improve the negative job image linked to seafarers by the public opinion. If the public image of seafarers can be improved and attractiveness rose, it is expected a higher number of seafarers will pursue and keep a career at sea.
In this study, with the awareness of the limitations set in the currently operated calculations of holding power and the holding power coefficient of anchors of naval ships due to its simple application of a specific value, various factors that impact the holding power and its coefficient were verified based on existing data analysis of literature research and numerous experiment results from anchor manufacturers, research institutes and academic community in order to overcome the aforementioned limitations. In addition, holding power and holding power coefficient were compared and analyzed by the shape of anchors. As a result, we came to know that the holding power of AC-14 type anchor is stronger than that of ASS type anchor or U.S. Navy Standard type anchor which makes it possible to reduce the weight of the anchor and therefore ease the process of naval shipbuilding. Furthermore, we confirmed the fact that U.S. Navy Standard type anchor does not react sensitively to the weight change of the anchor. Lastly, we found out that Danforth type anchor's holding power coefficient is in inverse proportion to the weight. Moreover, instructions for managing anchor are arranged easily for your information. The results of this study is expected to provide anchor - operating naval crew with a reliable theoretical basis pertaining to an anchor's holding power and its coefficient and contribute much for the safety of their act of anchoring.
Since the Cold war, many countries in the world have reduced the number of their military personnel. However, it is also factual that regional conflicts have been incessantly occurring around the world. In turn, specific governmental policies are also needed in certain countries. Recently, a resolution growingly accepted in the advanced countries is the outsourcing of the resources and services of private military companies, which benefits for governments to manage their military force efficaciously. The utilization of private military force, however, may potentially generate ethical and practical issues because of the non-specified international codes to regulate private military companies, the political misuse of private personnel without concerning the loss of public military employees in danger zones, the safety of private personnel in the field, and the possibility of genocide. Prior to accept a private military companies which may be adequate in the environment of the Korean military, it is necessary to review previous cases of foreign countries. In addition, it is also needed to determine the plausible boundaries of the operation of private military companies with taking into consideration of the situations of the Korean military and private business. Finally, the systemic governmental support is requested in order to foster the business of private military.
