음절 기반 모델은 음절 하나가 모델의 입력이 되며, 형태소 분석을 기반으로 하는 모델에서 발생하는 에러 전파(error propagation)와 미등록어 문제를 회피할 수 있다. 개체명 인식은 주어진 문장에서 고유한 의미를 갖는 단어를 찾아 개체 범주로 분류하는 자연어처리 태스크이며, 슬롯 필링(slot filling)은 문장 안에서 의미 정보를 추출하는 자연어이해 태스크이다. 본 논문에서는 자동차 도메인 슬롯 필링 데이터셋을 구축하며, 음절 단위로 한국어 개체명 인식과 슬롯 필링을 수행하고, 성능 향상을 위하여 한국어 대용량 코퍼스를 음절 단위로 사전학습한 ELECTRA 모델 기반 학습방법을 제안한다. 실험 결과, 국립국어원 문어체 개체명 데이터셋에서 F1 88.93%, ETRI 데이터셋에서는 F1 94.85%, 자동차 도메인 슬롯 필링에서는 F1 94.74%로 우수한 성능을 보였다. 이에 따라, 본 논문에서 제안한 방법이 의미있음을 알 수 있다.

The purpose of this study is to examine the global value chain of the global automotive industry to investigate the success factors through the example of the value chain of Hyundai Motor. It looks at the value chain of the well-known Korean automaker, Hyundai Motor, to find success factors with cases. It examines the process to build the supply chain of Hyundai Motor to analyze what impact it has on the growth of Hyundai Motor to look closely at the vertical division of labor of vehicle parts manufacturers. Korea's automobile industry has been expanding cooperation between two sectors as a multifunctional promotion focusing on electronic communications technology in machinery and technology center. Through introducing the nation's first vertical integration in the sector, Hyundai Motor has secured competitiveness of cost reduction and prestige car production. Hyundai Motor has operated and established factories in the United States, India, Turkey, the Czech Republic, Russia, and Brazil. Hyundai Motor operates 51 affiliates, such as Hyundai Mobis, by restructuring, mergers and acquisitions, and building their own vertical division of labor around it. Hyundai Motor has been overcoming dependence on foreign modules businesses and maintaining the supply value chain around Hyundai Mobis.

In this paper, paint-free metallic plastic material, polypropylene (PP) and acrylonitrile styrene acrylate (ASA) materials were investigated on the applications for bumper skid plate and outside mirror housing parts. In order to maximize metallic effect, type, size and content of aluminum pigment were optimized based on flop index. Hybrid aluminum pigments with different aspect ratios were used to conceal weld lines. By controlling the fluidity of the material, the flow mark problem, generated on the surface of the part, was resolved. We also investigated the surface defects of flow and weld lines by using the developed modeling and simulation.

Recently, the importance and requirement for Corporate Social Responsibility(CSR) is continuously growing in both korea and foreign countries. This paper tried to analyze on the theoretical trend of CSR and to draw out managemental implications for Korean firms' global CSR strategy by means of comparative case study for the CSR activities of Toyota and Hyundai Motor in China. The results and implications of this study are as follows. First, this study showed that these companies had carried out a systemic legal and ethical responsibility. Second, according to the model of Porter & Kramer and Ibuki Eiko, these companies had recognized the importance of CSR and had recently begun to implement their strategic CSR Third, Toyotas' CSR activities in China are more closely related to auto industry and more strategic in compare with Hyundai Motors' CSR activities in China. Fourth, therefore, the more strategic and long-term planned effective CSR activities of Korean firms in China will be needed in the future.

Motion Analysis of pedestrian headform was first applied in this paper for the purpose of determining the relationship between stiffness of hood and HIC. Since the analysis of headform movement involves rotation, it has been problematic if analysis of the headform movement is made in local coordinate system only. Correlation of test and simulation is expected to be enhanced through the development of New type of Head Movement Analysis Method.

A new dummy has improved biofidelity from Fair to Good compare with EuroSID2re which is currently used for regulation tests and NCAP tests. Some instrumentation of each body region has been changed to measure the assessment of injury risk. The objective of this study is to find out the injury characteristic of each dummy and to calculate the relation between external force and injury for each dummy with pendulum tests. Finally, this study suggests the optimized external force to meet consumer tests. A new dummy named WorldSID for side impact will be introduced into EuroNCAP tests after 2015. Korea government is also planning to adopt WorldSID at KNCAP tests from 2017 and Global Technical Regulation (GTR) will also adopt WorldSID to oblique side pole crash.

Even though the number of CO poisoning casualties caused by unintended idling for the vehicles equipped with keyless ignition systems is more than 70, the problem still remains unsolved and became social issue in the US, and Senates introduced the bill which urges NHSTA to make regulation for this accordingly. To meet market safety needs and the regulations, we decided to provide automatic shut-off system very soon. In this paper, we would like to describe how to validate vehicle shut-off timing including defining required tests and case selections considering vehicle condition, garage/room size and temperatures with several assumptions. We believe that safe implementation of the shut-off function is possible via this methodology and the results. As NHTSA must be interested in shut-off timing, the methodology can be enhanced and conclusions could be reflected highly in the future regulation in case we continue this study with NHTSA or any other 3-rd party institutes.
