High-tech industries in Taiwan exist in an environment with diverse product requirements and intense cost reduction and information integration stress. They must develop new operational directions to increase industry competitiveness. Therefore, Taiwan's high-tech industries must continue R&D and creativity, establish knowledge sharing mechanisms and improve new product development (NPD) performance. This research analyzed and explored the influences of knowledge management (KM) and knowledge sharing mechanisms introduced by Taiwan's high-tech industries on new product development performance. The relationship between knowledge management capabilities and NPD performance is studied. This research considers the intervening industry and corporate position variables. Taiwan's high-tech industries have gradually entered the era of IT region integration and application with competitive advantage creation based upon core techniques. The in-depth study of knowledge management and knowledge sharing introduced by the high-tech industry revealed double meanings in academic and practical applications. The research results showed the following: (1) the stronger the knowledge management capabilities of Taiwan's high-tech industries, the more significant the NPD performance. (2) The better the knowledge sharing mechanism in Taiwan's high-tech industries, the more significant the NPD performance. (3) Corporate scale is not necessarily the critical factor in NPD success and the influence of corporate scale on NPD performance did not show significant differences. (4) The stronger the degree of leading corporate techniques, the more significant the NPD performance.

A dynamic analysis using a hybrid finite element method was performed to characterize the effects of a number of manufacturing errors on bearing forces and critical tooth stress in the elements of a planetary gear system. Some tolerance control guidelines for managing bearing forces and critical stress are deduced from the results. The carrier indexing error for the planet assembly and planet runout error are the most critical factors in reducing the planet bearing force and maximizing load sharing, as well as in reducing the critical stress.

This paper studies a soft switching DC/DC converter to achieve zero voltage switching (ZVS) for all switches under a wide range of load condition and input voltage. Two three-level PWM circuits with the same power switches are adopted to reduce the voltage stress of MOSFETs at $V_{in}/2$ and achieve load current sharing. Thus, the current stress and power rating of power semiconductors at the secondary side are reduced. The series-connected transformers are adopted in each three-level circuit. Each transformer can be operated as an inductor to smooth the output current or a transformer to achieve the electric isolation and power transfer from the input side to the output side. Therefore, no output inductor is needed at the secondary side. Two center-tapped rectifiers connected in parallel are used at the secondary side to achieve load current sharing. Due to the resonant behavior by the resonant inductance and resonant capacitance at the transition interval, all switches are turned on at ZVS. Experiments based on a 1kW prototype are provided to verify the performance of proposed converter.

Static analysis using hybrid finite element(FE) method has been applied to characterize the influence of position, runout and thickness errors of the sun, ring and planet on the bearing forces and critical tooth stress. Some guidelines for tolerance control to manage critical stress and bearing forces are deduced from the results. Carrier indexing error planet assembly and planet tooth thickness error are most critical to reduce planet bearing force and maximize load sharing as well as to reduce critical stresses. Sun and carrier bearing forces due to errors increase several times more than those of normal condition.

The main purpose of the research was to prove, in a practical sense, the relationship among perceived equity, role stress and life satisfaction of employed wives working in sales departments. The subjects were employed wives working in sales departments who have at least one child and a spouse, living in Seoul and the Metropolitan area. The final data analysis used 487 out of 668 questionnaires. Statistical analyses were carried out using SPSS/PC WIN which included frequencies, mean, percentages, Pearson's correlation, Cronbach's ${\alpha}$, factor analysis, multiple regression analysis. The findings of the study were as follows: 1) As their education level was low, the education level of their spouse was high, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived emotional relationship was equal. As they were old, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived position in sharing household chores was equal. On the other hand, as they were younger, the education level of their spouse was high, the reason for getting a job lay in supporting the family, and overtime hours worked, there was a higher level of role stress. 2) The influential variables which affect the life satisfaction, in order of importance, were communication level between couples, mother's role stress, age, non-financial reason of getting a job, and sharing household works. For relative contribution degree about life satisfaction, psychological variables among independent variables were revealed as the most influential ones. Thus, efficient communication between couples affected the life satisfaction to a great degree. Furthermore, the study proved that not only role stress variables but also perceived equity variables contributed to the life satisfaction.

Since manufacturing and supplying corporations today come to view their practice of SCM as important, it becomes essential to analyze and control the structural relationship between the information sharing among corporations and the performances resulting from their practice of SCM. It is thus the purpose of this paper to examine the factors that may prompt corporations to implement SCM by means of analyses into the relationship between information sharing and practice of SCM which corporations should lay stress on as well as the relationship between financial and non-financial performances of corporations. The findings of the study can be summed up as follows: First, as for the relationship between information sharing among and practice of SCM by corporations, information sharing among corporations turned out to affect such factors of implementing their SCM as trust, commitment mutual dependence. Consequently, corporations are requested to endeavor to implement SCM itself faithfully if they really aim to achieve their performances by practice of SCM and, at the same time, to make efforts to obtain understanding and support for information sharing among themselves. Second, from the analysis of the relationship between SCM and financial as well as non-financial performances of corporations, it was found that trust, a factor of SCM practice, had influence upon non-financial performances of corporations, but not upon their financial performances, while commitment and mutual dependence affected both financial and non-financial achievements of corporations. Therefore, it was made clear from the analysis that the decision and systematic control of SCM activities which best suit to a corporation play an important role in improving its financial and non-financial performances, because they greatly depend on the implementing extent of SCM factors such as trust, commitment and mutual dependence among corporations.

본 연구는 여성가족패널조사(KLoWF) 제3차년도 조사(2012)를 활용하여 미취학자녀를 1명 이상 둔 여성 임금근로자 218명을 연구대상으로 선정하여 양육스트레스에 영향을 미치는 요인을 규명하였다. 연구결과, 가족내 역할인식이 높을수록, 남편 가사노동 분담에 대한 만족도가 높을수록, 양육비용이 적을수록 양육스트레스는 낮은 것으로 나타났다. 이러한 결과를 토대로 함의는, 첫째, 여성 임금근로자 자신이 전통적인 여성의 역할인식을 할 때 오히려 양육스트레스가 높기에, 이제는 주부의 취업에 대한 인식과 맞벌이 부부의 가사업무분담 및 주택의 부부공동명의 등 인식의 전환이 필요하다. 둘째, 남편 가사노동 분담에 따른 만족도가 양육스트레스에 유의미한 영향을 미치는 것으로 나타나, 향후 남편의 가사노동 분담의 효과성에 대한 접근이 필요하다. 후속 연구를 위한 제언은 여성의 직종 중 교대근무를 하는 직종비율이 높음을 감안할 때, 이들의 양육스트레스 등을 연구하기 위한 변수를 추가할 필요가 있다.

This paper intends to introduce a near-tip grid refinement and to explore its usefulness in the crack analysis by the natural element method (NEM). As a sort of local h-refinement in FEM, a NEM grid is locally refined around the crack tip showing the high stress singularity. This local grid refinement is completed in two steps in which grid points are added and Delaunay triangles sharing the crack tip node are divided. A plane-state plate with symmetric edge cracks is simulated to validate the proposed local grid refinement and to examine its usefulness in the crack analysis. The crack analysis is also simulated using a uniform NEM grid for the sake of comparison. The near-tip stress distributions and SIFs that are obtained using a near-tip refined NEM grid are compared with the exact values and those obtained using uniform NEM grid. The convergence rates of global relative error to the total number of grid points between the refined and non-refined NEM grids are also compared.
