Automobile industry has several characters such as high level of specialization, large volume of production, which plays a big barrier to entry of the industry. Therefore logistics outsourcing of automobile manufacturing company tends to make long-term contract with logistics service provider which also makes it difficult to outsource their logistics business to many different types of companies. Some vehicle manufacturing companies tend to outsource their several logistics to several companies while others outsource very limited number of logistics companies even only one company exclusively. This study aims to investigate various type of logistics outsourcing in terms of advantages and disadvantages and then carry out case study for Hyundai Glovis which is a global logistics company managing logistics service of Hyundai car maker in Korea. The focus is on how it can provide innovative and efficient logistics service with integration of global supply chain of Hyundai Automobile company.

This paper deals with cyclic stress and strain responses during isothermal low cycle fatigue (LCF) and thermo-mechanical fatigue (TMF) loadings on Nb and Mo containing 15Cr stainless steel, which is used for exhaust manifolds in automobiles. The test temperatures ($T_{i}$) of the isothermal LCF were 600 and $800^{\circ}C$. The minimum temperature of the TMF test was $100^{\circ}C$ and the maximum temperaures ($T_{p}$) were varied between 500 and $800^{\circ}C$. In both loading conditions, weak cyclic softening is observed at $T_{i}=T_{p}=800^{\circ}C$, but the transition to strong cyclic hardening is completed with the temperature decrease below $T_i=600{\sim}700^{\circ}C$ for LCF and $T_{p}=500{\sim}600^{\circ}C$ for TMF. The stress-strain hysteresis loops in the TMF loading show a significant stress relaxation during compressive (heating) half cycle at $T_{p}>500^{\circ}C$, which develops tensile mean stress during cycling. Due to the stress relaxation, the TMF test sample reveals much lower dislocation density than the isothermally fatigued sample at the same temperature with $T_{p}$. A detailed correlation between fatigue microstructure and cycling deformation behavior is discussed.

현재 자동차 산업은 기계공업의 꽃이라 불리며 그중에 엔진은 자동차의 심장이라 할 수 있다. 본 강연에서는 이 중요한 엔진이 제대로 작동하기 위해 Tribology에 근거한 설계 및 개발이 어떤 부분에 얼마 만큼 필요한가에 대해 간단히 기술해 보았다. 여기에 기술한 내용은 지면 관계상 개괄적인 낸용에 그칠수 밖에 없었지만, 간단히 말해서 '엔진은 Tribology의 덩어리'라고 표현할 수 있을 것이다. 현대 자동차에서는 그 중요성을 인식하여 이 부문의 연구에 최선을 다하고자 노력하고 있다. 그러나 Tribology 라는 학문이 망라하는 분야가 깊고 넓을 뿐만 아니라 여러 학문과 연관되어 있어 자동차 생산 업체의 노력 만으로는 한계가 있다. 그러므로, 이제는 Tribology 학문과 이에 근거한 기술의 발전을 위해 자동차 생산 업체는 물론 학계, 정유 업체 및 각 부품 업체의 긴밀한 협조와 공동 연구가 절실히 요구되는 시점이라 생각한다.

This paper proposes to examine the relationship between the two trade unions of Hyundai Motor Company (HMC) - those of the regular workers and of the in-house subcontract workers - around the issue of converting irregular workers to regular ones, which has been a social issue for a long time, and, furthermore, to find a desirable solution. The politics of the in-house subcontracting rotate around three axes: the conflictive collusion between the company and the regular workers'union regarding the internal labor market; the exclusion and resistance between the company and the subcontract workers'union; and the solidaristic conflict relationship between the two unions. After the final decree by the supreme court in 2012 the conflict and collusion/solidarity relationship of the three social actors have been amplified in scale - the continuous limping of the special bargaining between the company and the unions, the intensified conflict between the company and the subcontract workers'union, and the crisis of the collusion between the branches of the two unions are all evidence of this. A clue to the solution to the issues of in-house subcontracting in HMC can be found through reestablishment of the relationship among the three actors. In order to solve the in-house subcontracting issues in HMC, phased and lawful switching from irregular to regular positions, improvement of working conditions for the irregular workers, integration of the two unions (realization of 'one company one union'), and negotiated flexibility in the internal labor market will be required. Also to be considered are installation of a special committee for the issue, and utilization of external consultants. The result would be the possibility for the corporate labor market of HMC to be composed of regular workers, legal contract workers and directly-employed contract workers, which could be realized through bilateral relations of 'the labor and management conflict partnership'.

Since the European Union-South Korea Free Trade Agreement entered into force in 2011, the Korean automobile market has grown rapidly, resulting in intensifying competition among companies in the market. European automakers gained price competitiveness, which intensified competition with Korean automakers. In such a situation, various studies on the Korean automobile market have been conducted, but studies such as market influencing factor analysis and consumer analysis have mainly been conducted, and there is no research on the analysis of competitive dynamics in the market. In this study, the competitive dynamics between Hyundai Motors, Kia Motors, Mercedes-Benz, and BMW, which are major automakers in the Korean automobile market, are analyzed. The competitive relationship between major automakers are modeled using the Lotka-Volterra (LV) model and the competitive dynamics over time are analyzed by applying the Moving Window. In order to explain the competitive dynamics effectively, we analyze it by subdividing it based on various influencing factors.
