In order for humans and robots to interact in daily life, robots need to understand human speech and link it to their actions. This paper proposes a hierarchical behavior model for robot action control using natural language commands. The model, which consists of episodes, primitive actions and atomic functions, uses a sentential cognitive system that includes multiple modules for perception, action, reasoning and memory. Human speech commands are translated to sentences with a natural language processor that are syntactically parsed. A semantic parsing procedure was applied to human speech by analyzing the verbs and phrases of the sentences and linking them to the cognitive information. The cognitive system performed according to the hierarchical behavior model, which consists of episodes, primitive actions and atomic functions, which are implemented in the system. In the experiments, a possible episode, "Water the pot," was tested and its feasibility was evaluated.

A contact accident with gantry cranes involving the container ship MV Milano Bridge in Busan New Port took place on 6 April 2020. The report concluded that the pilot unreasonably piloted the ship with impaired maneuverability and without a proper pilotage plan. Analyzing the entire system by CAST model gives a holistic approach in linking all the key components and their roles as well as violations that led to the accident, stepping away from placing the blame on only one component in the system. Furthermore, analyzing the accident as an system theory gives a clear overview of the relationships between system components and how these interactions led to the accident.

Preliminary experimental results are reported on the response of reversed T type linking reinforced concrete shear wall. Different layouts of coupling beams were tested and stiffness degradation and energy dissipation of coupling beams were evaluated. Diagonally reinforced coupling beams with slab showed larger ductility and larger amount of energy absorption to be attained compared with conventionally reinforced concrete coupled beams.

This Grand Sorae Bridge was built in order to lead to balanced reigoonal development by linking the 2nd Seoul - Inchon Highway to WestCiast Highway and it will contribute to develop the economy of the region and traffic of its vicinities by helping ease traffic in and around Inchon. It extends 470 meter across Sorae port by using 10 continuous steel box griders under benoto(all casing) system considering ultra soft ground condition of the site.

A simple model for RAM (Reliability, Availability and Maintainability) analysis and its computer code are developed for application to DUPIC fuel fabrication system. The approach is obtained by linking the allocation model (top-down method) to bottom-up method for RAM analysis. As a result, the availability requirement of subsystem, as well as the buffer storage requirement between processes, are evaluated for the DUPIC facility..

Now operating of many urban railway lines are currently in progress in tile Seoul, but the inadequate consideration of links between different lines could create inconvenience as the public transport. This paper is studied about the connection design of urban-railway service convinced for other metropolis railways forms and propose the base pilot plan of the railway network linking system in Seoul Metropolis.

Parkinson's disease (PO) is a widespread neurodegenerative disorder. Even though PD has been studied in many aspects, it is still unknown the molecular signaling mechanisms linking reactive oxygen species (ROS) and neuronal apoptosis in PD. A better understanding of cellular mechanisms that occur in Parkinson's disease is essential for development of new therapies. In this study we investigated the signaling molecules involved in neuronal apoptosis induced by 6-hydroxydopamine (6-OHDA) in human SK-N-SH neuroblastoma cells as a model cellular system. (omitted)

This paper reports on the development of the analysis program of the valve train system, IV-TAP. It is essential to verify the stability of the design and to improve the performance of the system. In order to do that effi챠ently, it is required that integrated and interactive simulation analysis program. IV-TAP is developed in the base of the object-oriented, capsulation, modulization, OLE(objected linking and embedding) and variational design theory. So it contain the expandability and flexibility of the structure. In additon to that, it is programed to make the convenient user interface by using the visualization programming. It can support the modification of the valve element as well as the development of the valve system in the beginning. It is expected to reduce the money and effort for design the valve train system.
