While going into troops for writing in the vignette style(小品文) in opposition to the Classical Chinese(古文), Yi Ok stopped by Songgwangsa Temple in Wanju. The things he felt during this stop were recorded in the Temple Chapter ( 寺觀) written in 1795. Therefore, the present dissertation evaluates the Songgwangsa Temple of the time based on this Temple Chapter . Data in the Temple Chapter draws attention to the fact that it records the layout of the temple in detail. Thus the study was able to confirm the change in layout by reviewing relevant records about repair. This reveals that the form of layout in general has been maintained although there were changes involving the relocation of the buildings and their names. Furthermore, the original Buddhist building was changed to a quarter for the monks. Also, in terms of layout after the 18th century, there are frequent name changes of the Myeongbujeon(冥府殿) and Nahanjeon(羅漢殿). After two repairs, in order to find the appearance of a Daeungjeon(Main Buddhist hall) with a two-storied structure of five bays at the front, the study evaluated the Geugnakjeon at Muryangsa Temple and the Daeungbojeon at Magoksa Temple. The evaluation revealed that the ‘Jeol’ used in the Temple Chapter were small pillars erected on a ridgepole just like the Geugnakjeon at Muryangsa Temple, and that the angle rafters were installed to corner bays in rectangular form. The intellectual Yi Ok left behind invaluable architectural data that reveals the Songgwangsa Temple of the 18th century.

Preventive measures against industrial accidents should take into account the safeguards of unsafe states, education, and managerial measures to control the underlying sources of unsafe and unsafe behavior. Technical and managerial problems are also attributable to the educational cause. In particular, in the in-house safety education system, many construction sites form formal safety education.Inherent safety education is the best safeguard against disaster prevention. In the future, the safety education coordinator and the safety education coordinator of the management and supervision of the safety supervisor and hazardous hazard workers will need to improve the active legal system that can be pursued by all trained persons.

Safety accidents, which are called industrial accidents in construction work, are often caused by unstable physical and personal conditions combined during preparation and execution of work. It is difficult to manage all the construction works, but especially in the field of apartment construction work, complex and many kinds of works are being carried out at the same time. In the current construction, safety regulations such as safety management guidelines are generally well maintained, but the execution of manpower resources that can fulfill them is limited, and it is difficult to reduce the accident rate and loss cost. Therefore, in this study, it is a reality that most of the types of construction work are under contruction by subcontracting contract, so they are limit by methods of manual maintenance and safety education. Currently, the subcontractor is also allowed to perform safety management through the composition of the safety management review body, but it is operated formally. So alternatives to this were studied. As a result, safety accidents occur in the subcontractor's workplace due to vertical integration, which is a characteristic of the construction industry. Therefore, the safety management should be carried out by the subcontractor as well as the subcontractor It is concluded that effective and practical safety management can be achieved when management based on the personality that can communicate with each other through the management team is able to reduce the accident rate and loss cost.

In 2015, Baekje Historical Site was listed as a World Heritage Site. Therefore, the interest in Baekje heritage has increased rapidly, but there is insufficient research on how to utilize it. In addition, research on street composition based on historical and cultural resources is increasing, and it is necessary to find a way to establish and utilize local identity. The research method of this study is as follows. First, literature survey was conducted. Second, we used cameras to photograph the current status and color conditions. Third, the color characteristics of the photographs were analyzed through ‘Korea Standard Color Analysis (KSCA)’ program and ‘Easyrgb’ Internet program. For image analysis, we analyzed the I.R.I color sensitivity scale. Fourth, the characteristics of color and image and color characteristics and image of royal tombs in Gongju Baekje Historical Remains District were compared and analyzed by combining the results of Gongsan Fortress and Songsalli Ancient Tomb. The N and YR sequences were the most frequent in the Baekje Historical Remains. Wangneung-ro were N, Y, Y, B and R sequences. As a result of comparing and analyzing them, N and YR series were found, but the colors which were not seen in Baekje Historical Remains District such as B series and R series were derived. In addition, the Baekje Historical Remains District overlapped the ‘noble' image adjective area, and the adjectives such as ‘traditional’ and ‘calm’ were typical, but the ‘modern' adjective region overlapped with the royal tomb, Adjectives appeared as adjectives such as ‘urban' and ‘progressive'. As a result, it was found that the color characteristics and images of Baekje Historical Remains were opposite. It is considered that differentiated utilization methods are needed to establish the characteristics of the historic city and the identity of the princess. Baekje Historical Remains District is a place rich in potential to grow as a burial heritage representative of Korea. Therefore, it can be used as a strategy to strengthen the competitiveness of the region during the development of the history through the above research.

In construction work, safety accidents often occur in combination with unstable physical and human conditions during preparation and execution of work. In Korea, the accident rate is higher to that of any country in the world. Therefore, it is necessary to take measures by fundamental prescription. In this paper, in the case of construction safety management, we tried to find a reasonable alternative through a questionnaire survey to apply to subcontracting and small-scale construction. In conclusion, workers who are well aware of the task could be able to reduce the accident rate by deploying them as safety management officers after receiving the training.

Safety accident in Building construction work in the process of preparation and implementation of the insecure human, material status is often caused by combining the reality is that many things. Accident rate is a similar level in the case of Korea and foreign countries than any country in the measures by the higher fundamental prescription is needed. In this paper, construction safety management of subcontracting work and small construction plan to apply through a survey to reach a sensible alternative. I did In conclusion, the educated workers know well, and so on the work schedule then quickly if safety management personnel in disaster will be able to reduce the rate to a miracle appeared.

This paper aimed to identify a main-path remains in the Hwangnyongsa temple site based on studying published the excavation survey report and researching relics related to the path in the ancient temple site. Hwngnyongsa temple, there were three type’s paved footway, straight path to the central axis line of the layout, outside path around the main buildings and the front square of the lecture hall. These remains were expected that installed for some purposes, such as marches, touring, sort of a Buddhist ceremony been performed at the time of Silla. Straight path shows there were two rows of the main access inside the roofed corridor. A row consisted of the 2～3 pieces processed stone(Jangdaeseok) altogether with 92cm width and combined with square stone and stepping stone on the end of the road. It is regarded as very characteristic form and one of the architectural elements of Hwangnyongsa temple in Unified Silla period.

Due to increased demand for remodeling and repair in construction market in recent year, the usage of horse scaffold is increasing in the indoor finish works. Injuries related horse scaffold are mainly caused by poor installation or of careless handling of scaffold. Approximately 300 workers are injuried at construction site every year, it is accounting for about 1.5% of the total construction sector and has increased on a year-to-year trends. But the main contents between national standards and speccifications related to the manufacture and usage of horse scaffolds are mutually inconsistent, In particular, the rules on occupational safety and health standards are the basis for the prevention of industrial injuries, there is no explicit application being made to the horse scaffold commonly used on construction sites. The purpose of this study was to analye the manufacture and usage situations in order to reduce construction injuries that occur at the horse scaffolds. It will be utilized the results of the analysis as the basis data for unifying the major domestic standards and specifications associated with the manufacture and usage of horse scaffold.

The validity of landfill gas models is an important problem considering that they are frequently used for landfill-site-related policy making and energy recovery planning. In this study, the Monte Carlo method was applied to an landfill gas generation model in order to enhance conformity. Results show that the relative mean deviation between measured data and modeled results (MD) decreased from 19.8% to 11.7% after applying the uncertainty range of Intergovernmental Panel on Climate Change (IPCC) to the methane-generation potential and reaction constants. Additionally, when let reaction constant adjust derived errors from all other modeling components, such as model logic, gauging waste, and measured methane data, MD decreased to 6.6% and the disparity in total methane generation quantity to 2.1%.

Seven outbreaks of foot-and-mouth disease (FMD) have occurred in South Korea during the period January 2000-September 2015. The Korean government changed national goal to FMD-free country with vaccination after the November 2010 outbreak when approximately 3.5 million cattle and pigs were culled. With regard to vaccination, Korean pig producers have claimed that the occurrence of injection site reaction (inflammatory or non-inflammatory granuloma) is potentially associated with intensive vaccination campaign since 2011. The present study was undertaken to assess the incidence of injection site lesions in slaughtered pigs caused by FMD vaccination and the corresponding economic losses. Data obtained from two meat packers were classified into 3 vaccination periods: non-vaccination (July-November, 2010, n=96,959); one injection (July-November, 2014, n=162,089); and two injections (March-July, 2015, n=161,928). A total of 420,976 carcasses from 6,526 farms were analyzed. The incidence of the lesions was 18.6% for non-vaccination, 46.5% for one injection, and 73.7% for two injections. Economic loss per head slaughtered due to removal of the lesions was estimated to 1,302 won (US$ 1.1) for non-vaccination, 8,286 won (US$ 7.2) for one injection, and 17,378 won (US$ 15.1) for two injections (converted using 2015 exchange rate where Korean won 1,150 = 1 US$). It was estimated that the national annual losses excluding costs of an FMD vaccine and its application is US$ 115 million for one injection and US$ 241 million for two injections. The adoption of measures that cause minimal tissue damages and economic losses would appear to be of high priority.

In this work, on-site corrosion behavior of heat resistant tubes of T91, used as components of a superheater in a power plant for up to 25,762 h, has been investigated using scanning electron microscopy(SEM), energy dispersive X-ray spectroscopy (EDS), and electron backscattered diffraction(EBSD), with the objectives of studying the composition, phase distribution, and evolution during service. A multi-layer structure of oxide scale was found on both the steamside and the fireside of the tube surface; the phase distribution was in the order of hematite/magnetite/spinel from the outer to the inner matrix on the steamside, and in the order of slag/magnetite/spinel from the outer to the inner matrix on the fireside. The magnetite layer was found to be rich in pores and cracks. The absence of a hematite layer on the fireside was considered to be due to the low oxygen partial pressure in the corrosion environment. The thicknesses of the hematite and of the slag-deposit layer were found to exhibit no significant change with the increase of the service time.
