This study is about the architectural publicness of cost guard substation located in Busans fishing port. The development of cities are causing fishing villages to be included in cities, and the phenomenon of being neglected or killed in functional incongruity is being witnessed. In this situation, interest in the ocean is increasing due to the increase in individual leisure time, and it is attracting attention as a center of marine tourism. In line with this, the government is pushing ahead with its fishing port development policy, but discussions on qualitative improvement and understanding of public services and public spaces have not been made due to the plan focused on aesthetic aspects and programs. Therefore, this study attempts to analyze and evaluate the Busan cost guard substation from the perspective of the architectural publicness discussed in fishing ports. Analyzing cost guard substation by dividing them into internal and external public elements, and discuss how to implement architectural publicness from the wide context to the elements of interior space. Based on this, the purpose of the study is to make suggestions on how to implement future-oriented publicness, and this study is meaningful in that it looked at public buildings in Busan from the perspective of architectural publicness.

An excavator is a construction machine that can perform various tasks such as trenching, piping, excavating, slope cutting, grading, and rock demolishing. In the 2010s, unmanned construction equipment using ICT technology was continuously developed. In this paper, the path design process was studied to implement the output data of the decision stage, and the path design algorithm was developed. For example, the output data of the decision stage were terrain data around the excavator, excavator mechanism information, excavator hydraulic information, the position and posture of the bucket at key points, the speed of the desired bucket path, and the required excavation volume. The result of the path design was the movement of the hydraulic cylinder, boom arm, bucket, and bucket edge. The core functions of the path design algorithm are the function of avoiding impact during the excavation process, the function to calculate the excavation depth that satisfies the required excavation volume, and the function that allows the bucket to pass through the main points of the excavation process while maintaining the speed of the desired path. In particular, in the process of developing the last function, the node tracking method expressed in the path design table was newly developed. The path design algorithm was verified as this path design satisfied the JCMAS H02 requirement.

현재 천공장비 및 천공방법에 대한 많은 연구가 진행되고 있지만 DTH hammer의 타격성능을 규명하고 최적화에 대한 연구는 전무하다. 또한 DTH drilling의 시험 장비를 구축하기 위해서는 막대한 비용과 많은 시간이 요구되기 때문에 성능규명에 있어 시험적으로 접근하기가 매우 곤란한 실정이다. 따라서 본 논문에서는 DTH hammer의 구동원리를 파악 후 공압 해석을 이용하여 구동 특성 및 성능을 규명하였다. 또한 실험계획법을 이용하여 DTH hammer의 성능에 영향력이 있는 설계인자를 도출하고 이를 다구찌 기법에 적용해 DTH hammer의 타격성능인 타격수와 타격에너지의 최적화에 대한 연구를 수행하였다. There are a number of studies concentrating on drilling equipment and drilling methods, but none investigates the impact performance and optimization of DTH (down-the-hole) drilling. It is very difficult to experimentally evaluate the performance of a DTH hammer, because putting together an experimental setup for DTH drilling requires a great deal of money and time. Therefore, this paper examines the characteristics and performance of DTH hammers through pneumatic simulation after a thorough investigation of their working mechanism. In addition, the parameters linked to the performance of DTH hammers were selected using the design-of-experiment method, and then the optimization of performance factors, which are the impact rate and impact energy, was investigated using Taguchi method.
