Purpose - This case study is dedicated to the study of the presence of KIA Motors in the Kingdom of Saudi Arabia (KSA) and its market and entry strategies for strategic globalization that allowed the company to establish itself within a conservative and clustered marketplace dominated by American and Japanese international brands. Research Design, data, and methodology - The main information for the case was gathered through an interview and questionnaire from the executives of the KIA Al Jabr, which got the exclusive dealership in Saudi Arabia. Moreover, secondary data were obtained from reliable and authoritative sources such as the Saudi government agency publications, newspapers, international business journals. Other related periodicals based on the results from previous and current studies on similar topics were critically reviewed as well. Results - The findings of this paper show the different business environments of the Saudi market and the importance of various points regarding the company's global entry strategy even if the host market culture is quite different in many ways from other international markets. Conclusions - This case can provide Korean companies interested in the Middle East with insight into market penetration and global strategy, and present various perspectives and implications for global market access as well.

This study has developed a packaging criterion to minimize the level of discomfort which drivers using their vehicles for daily life purposes may experience due to ill designed vehicle packaging of mid-size sedan based on users' daily-life scenario. To find out optimal range of packaging dimension criterion, discomfort levels the test participants with different physical conditions suffer while performing various activities were analyzed. One hundred two test participants were carefully selected to represent entire Korean mid-size sedan owner-drivers. They were directed to test drive on the course designed to simulate mid-size sedan daily-usage scenario. At pre-designed locations, each of questions was asked to the test participants to be answered in the form of 10 point discomfort level score. By analyzing the test results, the optimal range for packaging dimensions was defined to be used as a packaging criterion.

A military vehicle undergoes normal to extreme driving conditions, which consequently induce the fatigue and fracture of cabin and frame. So, it is important to estimate the fatigue life of two components at an initial design stage. In this paper, Modal Superposition Method(MSM) was applied to evaluate the durability performance of a small-sized military truck. For reliable durability analysis, a Virtual Test Lab(VTL) Model was established by correlation with experimental results. These data were extracted from actual driving test, modal test, and SPMD(Suspension Parameter Measuring Device) test. This process shows that Virtual Fatigue Analysis can be a useful approach in the development of military vehicles as well as commercial vehicles.

연료전지차 및 하이브리드차용 전기구동시스템의 냉각성능은 차량의 동력성능을 보장하기 위한 중요한 요소이다. 각 단품의 성능 확보를 위해 냉각수를 허용 온도 이하로 관리해야 하며 이때 라디에이터 방열량과 냉각수 유량이 중요 변수가 된다. 본 논문에서는 현대자동차 연료전지차량의 모터, 인버터를 포함한 100kW 전기구동시스템의 최적 냉각 설계를 위하여 차량주행모드에 따른 전기동력부품의 발열량을 이론적으로 산출하고, 시험을 통하여 냉각시스템의 성능을 검증하였다.

Efficient algorithm for the solidification simulation by FDM is described from the practical point of views. If a proper time step ${\Delta}t$ is selected, the calculation is accelerated by implicit algorithm with the temperature recovery method of latent heat method. The implicit routine in the calculation is processed by SOR method(relaxation factor＝1.5, truncation error＝$10^{-4}$). The calculation is more accelerated by linear-interpolated explicite algorithm with a time step larger than the minimum value of the time step. This explicit method, which is applicable to the practical casting simulation problems, produces almost same results with about 40% faster calculation speed compared with the conventional explicit method.

Diesel particulate filter (DPF) has been developed to optimize engine out emission, especially particulate matter (PM). One of the main important factors for developing the DPF is estimation of soot mass being accumulated inside the DPF. Evaluation of pressure drop over the DPF is a simple way to estimate the accumulated soot mass but its accuracy is known to be limited to certain vehicle operating conditions. The method to compensate drawback is adoption of integrating time history of the engine out PM and burning soot. Present study demonstrates current status of the soot estimation methods including the results from the engine test benches and vehicles.

차량 전장품 중 와이어링 하네스에서 큰 전류가 흐르는 회로의 연결 단자가 가지는 전기적 내구 성능 및 기계적 성능을 확보하기 위하여 단자 압착부의 압축율 최적화 기법을 개발하였다. 우선 단자 제작 과정을 표준화한 후 압착부의 주요 인자인 기계적 인장강도와 내부 부식 정도에 의한 전기적 저항 중대로 화재가 발생 가능성 관점에서 접근하였다. 여러 가지 실험을 통하여 얻어진 DATA를 분석한 결과 회귀 2차 모형을 사용하여 대전류 단자 압착부의 전기적/기계적 내구 성능 최적화 구간을 설정 하였으며, 이의 과정을 제시 하였다.

The effect of drawing rate on the electrochemical properties of 3003 Al alloys in 5 wt.% NaCl solution was investigated by electrochemical techniques (potentiodynamic polarization test, potentiostatic polarization test, electrochemical impedance spectroscopy (EIS)) and surface analyses (OM, SEM, EDS). Four kinds of automotive pipe materials were prepared (raw material, drawing rate = 5, 10, 15%). As the drawing rate of Al alloy tube increased, the pitting corrosion resistance increased due to the enrichment of Al oxides on the surface.

Purpose: Taking Tesla Motors as a case study object, this research aims to summarize the management strategy of Tesla Motors through an evaluation of its business models in Korea and China then helps other new energy automobile enterprises in formulating strategic directions in a targeted manner. Research design, data and methodology: Using the case study method, this study conducts in-depth research on the business model of Tesla, a representative enterprise of the new energy automobile industry. This study mainly uses secondary data obtained from the official websites to support our research. Results: With its top-level innovative technology, distinctive marketing model, and extensive strategic model, Tesla holds the largest share of the new energy vehicle market. Local market brands such as BYD and Hyundai-Kia still have a considerable competitive advantage, and there is a need to learn from each other for further development. Conclusions: To adapt to the needs of economic transformation and environmental development, implementing business strategies related to new energy automobile enterprises is a topic worthy of study. Enterprises such as BYD and Hyundai-Kia have unique advantages in their home markets. However, as sustainable development progresses, these advantages will gradually weaken, and further measures are necessary to maintain their competitive advantage.
