  • The purpose of this study is to examine the role of safety sheriffs and their necessity in order to improve the activation of safety sheriff's professionalism. Seven security sheriffs were finally selected to discuss their activities and discuss ways to improve their effectiveness. We conducted semi - structured interviews and conducted in - depth interviews with limited data and inadequate prior research. The results of this study are as follows. First, the government should get the help of citizens, citizens and residents. If the state wishes to reduce the number of safety accidents and bring positive results to the public, it should not rely solely on the utilization of institutions. Second, in order to be a safe sheriff with a positive response from the local residents, the activities of the sheriff's sheriff are not only aimed at preventing risks in the environmental domain and reducing the number of accidents, Publicity should be provided to the landlord, tenant, and residents to inform them that the activity is preventive of accident prevention. Third, under the current law, it is necessary to disclose public facilities such as roads, airports, and harbors to the private sector in order to make it possible to monitor school facilities and youth training facilities. Fourth, the safety sheriff is expected to put forward the expectations and positive results of prevention through the beginning of the inspection activities, and the role of the Korean people in becoming psychological stable and efforts to be born as safety experts are required. Finally, it is necessary to establish a concrete manual, strategic safety inspection plan.

  • Ancient tombs are typically comprised of confined rooms, which have different spatial characteristics than the external environment because they are covered by heavy layers of soil. In this study, we examined the thermal energy flow from the outside to inside of Songsan-ri tomb No. 6. External heat flows slowly to the inside because of heavy soil layer, and the presence of several rooms and entrances. For this reason, it takes about two months for the air temperature to travel from the outside to the inside of the tomb. Interestingly, the gradational inflow of thermal energy from outside the tomb leads to delicate horizontal and vertical variations in the wall temperature. These micro-environmental differences occur in the inner tomb every year, so we can expect them to cause condensation with regularity. In addition, we show that the previously installed forced circulation air conditioning system risks fatal damage to the mural wall painting. The results of this research suggest an optimal air conditioning system and optimized space planning to conserve Songsan-ri tomb No. 6 and its mural painting.

  • The rainfall pattern analysis on time distribution characteristics of rainfall rates in important in determination of design flow for hydraulic structures, particularly in urban area drainage network system design. The historical data from about 400 storm samples during 31 years in Seoul have been used to investigate the time distribution of 5-minute rainfall in the warm season. Time distribution relations have been deveolped for heavy stroms over 20mm in total rainfall and represented by relation percentage of total storm rainfall to percentage of total storm time and grouping the data according to the quartile in which rainfall was heaviest. And also time distribution presented in probability terms to provide quantitative information on inter-strom variability. The resulted time distribution relations are applicable to construction of rainfall hyetograph of design storm for determination of design flow hydrograph and identification of rainfall pattern at given watershed area. They can be used in conjuction with informations on spatstorm models for hydrologic applications. It was found that second-quartile storms occurred most frequently and fourth-quartile storms most infrequently. The time distribution characteristics resulted in this study have been presented in graphic forms such as time distribution curves with probability in cumulative percent of storm-time and precipitation, and selected histograms for first, second, third, and fourth quartile stroms.

  • Hangzhou, in China, is a city that has a history as long as 2,300 years and is renowned due to its natural scenery of a beautiful lake surrounded by gentle green hills. This world wide famous scenery, known as West Lake(西湖), in 2011, was included in the World Heritage Landscape List. Though this place experienced enormous development and changes during thousands of years, historic sceneries did not disappear with the passage of time. In contrary, they are refined and increased attributing to protection efforts from past dynasties. Therefore, research in landscape transition is significant for building livable environment and preserving historical landscape. This paper mainly focuses on history transition of city Hangzhou. First of all, its urban construction and guiding ideology is analyzed. Then, deep meticulous research is carried out on development and preservation achievements for dynasty Tang, Song, Yuan, Ming and Qing. In the end, from a historical point of view, this paper will provide a new perspective which would contribute to sustainable preservation of historical landscape. From the Song Dynasty to the Qing Dynasty, the West Lake through several times of the rectification and construction, the present landscape was completed during thousand years several times through the construction.

  • This study is to discuss the problems due to the maldevelopment occurred at the reserved areas of natural environments of the Ulleung Island, Gyeongsangbuk-do province, and it also suggests the ways of solving them The types of the maldevelopment practiced on the Ulleung Island consist of the change of land use, the opening of a round road, the destruction of mountains for the construction of harbor, the development of tourist areas, and the construction of military facilities. The decreased habitat of animals and the pollution of drinking water are occurred by the change of land use. The destruction of ecological system is due to the opening of a round road. The damage of natural landscape and the change of ocean eco-system is closely related to the construction of harbor and the destruction of mountains. Finally, the damage of rare plants and the pollution of drinking water are due to the development of tourist areas and the construction of military facilities. In the followings, the ways of solving the problems occurred by the various types of maldevelopment are suggested. First, the planning of pro-environmental development has to be established and practiced to preserve rare plants which are damaged due to the change of land use. Second, the destruction of natural landscape and resources has to be minimized by the implementation of environmental impact assesment when road and harbor are constructed. Third, the stones needed for the development of islands ought to be imported from mainland. Fourth, the established tourist areas are needed to rationally manage and the potential tourist areas has to be transferred to the reserved areas of natural environments. Fifth, military facilities should be constructed though the cooperation of autonomous local government. Finally, government officers' and residents' conscience of protecting and reserving natural environments is needed, and government has to give residents financial supports.

  • As the needs for fast wireless communication technology in various fields, including companies, individuals, etc., grows, many research projects related to the coverage of propagation are being carried out for plaining optimized communication services. On the other hand, there are some limitations in surveying and analyzing propagation in highland areas. To provide a better communication service of a new service, a range of radio environment conditions based on a wide radio bandwidth (selection of propagation model, correction of value in accordance with radio bandwidth, etc.) should be considered. In particular, radio environment conditions are becoming increasingly sophisticated. By the early detection of real-time changes in the radio spectrum, which is based on an examination and research of regional occupied band width condition, proper measures should be established. To make a proper solution of above, the basic real-time analysis of spectrum distribution status by regional groups is necessary. In addition, the establishment of prompt measures should be enable by stored or analyzed radio data. In an attempt to predict reliable propagation coverage, this thesis examines the limited propagation data with HTZ Warfare, which were collected from domestic high land sites faced with limited access. Furthermore, a comparative result value evaluation for an optimized propagation model was performed through testing simulations, and frequency-dependent and propagation model-dependent analysis.

  • In the case of government policies related to the Arctic Ocean, there is a "Northern Sea activity promotion basic plan" presented by the Ministry of Maritime Affairs and Fisheries, but it is difficult to adjust the timing of the policy enforcement and consider the importance of policies because no concrete order of enforcement of policies or weight has been presented by the government. In view of this, the purpose of this study was to estimate the priorities of the government's Arctic policies. Additionally, this study also presents priorities for "support measures" and "foreign cooperation measures" for the smooth implementation of Arctic policies. As for the methodology of this study, the CFPR (Consistent Fuzzy P reference Relations) method, which can comprehensively estimate expert opinions, was applied. According to the results of the analysis, the most important Arctic policy of the government was shown to be "Cooperation for Shipping and Logistics, such as Pioneering Northern Sea Routes" (0.087), followed by "Fostering Professional Manpower" (0.086), and "P reparing Institutional Foundation and Blueprint" (0.085). The results of this study have implications for the establishment of Arctic Ocean-related policies by policymakers as well as authorities.

  • With the removal of underwater obstacles in the Busan New Port, the water depth of the pier has been secured up to 17m, and the port authority is constantly responding to the trend of container vessels becoming larger. Also, in 2020, 24,000TEU class container ships are entering to the port, and it is planned to secure the depth in the port to 23 m later in line with this trend. Mega container ships must check in advance the factors to be considered depending on the situation at the time, and for this, it is judged that information sharing among stakeholders is necessary. In this paper, to understand the effect of the corresponding route because of the mega container ships, a transit safety evaluation was conducted based on statistical data on ship entry and departure and maneuver characteristics of corresponding ships. The result showed that the transit of the mega container ships has increased up to 8.4% comparing to the risk of 4,000TEU class container ships. Additionally, safety measures such as minimum safety depth and tug operation plans were presented by gathering opinions on operational characteristics from the perspective of pilotage for safe transit in the Busan New Port area. Through this, it is considered that it will be possible to contribute to the prevention of accidents when entering and leaving the Busan New Port.
