The purpose of this paper is to suggest a method for applying a reasonable dam axial seismic load loading method and load-bearing capacity evaluation method in the dynamic analysis of the pier part of a concrete dam to which the seismic force of the collapse prevention level is applied. To this end, the pier part of a concrete dam was selected as a target facility, and the characteristics of the dynamic behavior in the axial direction of the weir dam were analyzed through dynamic analysis applying various weir widths, and 'U.S. The load-bearing capacity evaluation was performed by applying the RC hydraulic structure evaluation technique suggested by the Army Corps, 2007'. As a result of the study, when applying seismic force in the axial direction of the pier part, it is more realistic to assume that the axial direction of the weir part dam behaves as a rigid body and 'U.S. Army Corps, 2007' suggested that the method of reviewing the load-bearing capacity for moment and shear was considered reasonable, so it was concluded that improvement of the current evaluation method was necessary. If the improvement of the research result is applied, it will have the effect of deriving more reasonable evaluation results than the current seismic performance evaluation method using CLE. It is judged that additional research is needed in the future on the torsional moment occurring in the pier part.

This study is to analyze open work status and conditions of cadastral surveyors and suggest improvement plans for working area of cadastral surveyors. The results are as below. Based on the analysis, this study suggests expansion of confirmation surveying for cadastral target range, ease of confirmation surveying standard for cadastral, and broader participation opportunities for cadastral surveyors in the cadastral re-survey project as improvement plans. If the Ministry of Land, Infrastructure, and Transport seeks legislative and policy improvement that can create more rational and ideal cadastral surveying conditions based on various reviews on improvement plans for working area of cadastral surveyors in this study will promote symbiotic development among cadastral surveyors.

As a result of the study on a number of the works, published in Russia, the methodical aspects of experimental improvement on working capacity of LRE (Liquid Rocket Engine) are reviewed. In the article, on the basis of the experience of Russia and USA, the special features of experimental improvement on working capacity of LRE and the methods of its rational implementation formulated. The organizational and technical solutions of experimental improvement on working capacity of LRE for achieving the required level of the reliability and decreasing the material expenditures are presented in the article. These suggested solutions can be used for the development of LRE.

This paper proposes the scheme to improve the current direct load control(DLC) program by inspecting the problems of the DLC program. In order to increase the number of the customers participating DLC program, a reduction of the base incentive and an increase of the direct load control incentive are suggested based on the interruption cost of electric power considering the characteristics of load types and the introduction of demand side bidding is recommended. Secondly, the standards of power system operations is required to control DLC program efficiently for the penalty, interruption times, the number of interrupting loads, notice time for the load interruption and the periods of the DLC program contract.

Linked treatment refers to a system that relieves the burden of the business by linking high concentrations of wastewater such as human waste, manure, leachate, and other industrial wastewater to nearby municipal wastewater treatment plants(MWTPs). In 2018, 187 MWTPs, which are about 4.5% of the total domestic MWTPs, have implemented a linked treatment system, but local governments are having difficulties in operating sewage treatment due to lack of reasonable cost estimation standards. Therefore, we proposed an improvement plan to solve the problem in the calculation method that currently imposes linked wastewater. To this end, the effects and correlations of the linkage treatment system on the sewage treatment unit were analyzed, and among them, the main factors with the highest correlation were applied to the improvement plan. As a result, an improvement plan that improved three parts of the existing calculation method was presented, and the calculation method and the calculation case using the existing literature values were also presented. This can be used as a basis for future reference by local governments to implement linkage treatment, and to revise local sewerage ordinance and is believed to be helpful in operating a rational linkage system.

Recently, high-concentration linked wastewater has been introduced into a nearby municipal wastewater treatment plants(MWTPs), but it is difficult to MWTP in local governments due to an unreasonable linked treatment charge system, and there is insufficient evidence or data to prove this. However, the MWTP, which is a national essential infrastructure, is generally exempt from the preliminary feasibility study, so there have been no cases where economic evaluation was conducted. Therefore, we proposed an improvement plan that can compensate for the disadvantages of the existing linked processing charges through previous studies. In this study, a comparative evaluation of how much economic feasibility can be improved compared to the existing ones when applying the improvement plan by conducting an economic analysis. For this, reference was made to the preliminary feasibility assessment data of the existing environmental facilities and the cost factors and benefit factors established during the modernization of the old sewage treatment facilities. As a result of the study, the B/C(Benefit/cost) value was quite low in the past, but when the improvement proposal proposed by the researchers was applied, it was confirmed that the B/C value increased close to 1. Therefore, it is considered to be very reasonable to calculate the linkage processing charge according to the linked wastewater load proposed by the researchers.

지난 5월말 현재 돈육(부분육) 수출실적은 750만불로 목표액인 900만불의 83$\%$에 이르고 있으며, 수출의 호전으로 생돈가격이 폭등되어 kg당 650원이라는 예년에 볼 수 없었던 가격을 형성하고 있는 실정이다. 이러한 호경기가 장기간 계속되리라고는 아무도 예측할 수 없으므로 수급 조절면에 세심한 주의를 기우려야 할 것이며 종자의 개량, 사양관리의 개선, 새로운 기술도입과 합리적인 경영 등을 실현하여 우리나라 양돈업의 근대화에 박차를 가해야 하겠다. 지난 수년간의 경험을 되살려 무모한 증식이나 불량돈육의 생산으로 국제시장에서의 외면 등의 불행한 사태가 생기지 않도록 서로가 협조하여 80년대를 향한 축산번영을 위하여 총력을 기울여야 겠다.
