  • Push-pull strength has been found to be associated with various work factors such as height, distance, repetition, duration, posture and individual factors. Therefore, this study was performed to investigate the effect of various work factors on push-pull strength and muscle recruitment pattern. Work factors were consisted of grip height(elbow, shoulder), grip distance(100%, 50%, and 25% of maximum grip distance) and shoulder angle(neutral($90^{\cire}$), and abduction($45^{\cire}$, $0^{\cire}$)) during sitting work. The results showed that the normalized strength and EMG value were higher at the elbow height than the shoulder height, and increased with grip distance and shoulder adduction. The results of ANOVA showed that there was significant difference on muscle recruitment patterns among the task conditions. Therefore, it is necessary to consider work factors as well as strength to prevent workers from work-related injuries.

  • The purpose of this study was to identify the individual, emotional, parent, and social environmental factors on career decision-making in multicultural youth. To this end, 1,146 multicultural adolescents who were enrolled in high school and whose fathers were Korean were selected as subjects of analysis as data for the 7th year of the Multicultural Youth Panel (MCAPS). As a result, first, it was found that self-esteem, which was an individual factor, and adaptation to school life and multicultural acceptance, which are social and environmental factors, positive effect career decision-making. Second, it was found that depression as an emotional factor and neglect as a parent factor had a negative effect on career decision-making. However, it was confirmed that stress as an individual factor, and parent-child communication as a parent factor did not affect career decision-making. These results are meaningful in that they provided basic data on how to deal with each factor and prevent multicultural youths from wandering in advance without deciding their career paths.

  • Software Process Improvement(SPI) has been a challenging issue to software organizations. The factors affecting SPI were analysed for improving software development processes. Numerous studies suggested influencing factors, and assessment models were utilized for software improvement. This research suggested that SPI factors affecting on an organizational performance may vary according to the CMM(Capability Maturity Model) level. The moderating effects of organizational maturity level between the SPI factors and the organizational performance were empirically tested. This research found that all six SPI factors except for the resistance to change affected the organizational performance. The moderating effects of management support, goal alliances, participation, and effect analyses were empirically supported. These results can provide several implications or a practical guidance to academic and industry professionals.

  • In this study, we individualize the clauses to sort out the troubled ones, draw up a interrelation model in order to visually organize the relations, and finally, suggest the desirable application idea. The interrelation model suggested in this study has been made based on the matrix method. On this matrix, we arranged the environmental factors on horizontal and vertical axis, and when we describe the relation of each factors, we set the horizontal axis as the base and divided the content into three grades : Fine, Medium, and Poor. In addition to that, we expressed those three grades into numerical value like 3 points for Level Fine, 2 points for Level Medium, and 1 point for Level Poor and then, we converted this numerical values into index numbers. We could classify the index numbers such as AS, PS, Q-index, P-index. AS is an index numerically shows the degree of giving environmental effect, PS is an index numerically shows the degree of receiving environmental effect, Q-index is an index shows the aggravate degree, and P-index shows the relation degree. The Q/P-index with large numbers has considerable effect on the environmental system, while the small numbered Q/P-index barely effect on the environmental system. Moreover, we classified the environmental factors into 5 levels(I~V) according to the relations between the Q-index and P-index. Level I is less affected by the environment and has more giving effect, while Level V is more sensitively affected by the environment and has more receiving effect, which we considered important. Therefore, we could come up with the result that if we consider the each level of factors when we evaluate the EIA, the result would be far more accurate and reliable since it contains mutual relation aspect of EIA. The suggested interrelation model in this thesis is presentable as one of those scoping system. We highly believe the need of scoping system in EIA and suggest the interrelation model as the alternative idea for scoping system.

  • Thermal characteristics, such as diffusivity and temperature induced change in the fiber mode index of rotation sensing fiber coil are critical factors which determine the time varying, thermo-optically induced bias drift of interferometric fiber-optic gyroscopes (IFOGs). In this study, temperature dependence of the transient effect is analyzed in terms of the thermal characteristics of the fiber coil at three different temperatures. By applying an analytic model to the measured bias in the experiments, comprehensive thermal factors of the fiber coil could be extracted effectively. The validity of the model was confirmed by the fact that the extracted values are reasonable results in comparison with well known properties of the materials of the fiber coil. Temperature induced changes in the critical factors were confirmed to be essential in compensating the transient effect over a wide temperature range.

  • There have been quite many studies to identify factors affecting successful implementation of EDI systems. However, previous studies have investigated influencing factors independently. Given the complexity involved in the implementation of EDI systems, it might be quite necessary to investigate the interaction effects between influencing factors. The primary purpose of this study is to investigate the interaction effects of organizational characteristics as contextual variables on the relationship between managerial characteristics and EDI implementation. Analysis of 202 responses of survey questionnaire indicates the following: 1) Education/training and top management support has positive effect on the successful EDI implementation. 2) The degree of decentralization has strong, and management risk position has mild moderating effect on the relationship between managerial characteristics and EDI implementation. 3) The degree of formalization and organizational size have no moderating effect. 4) The subgroup analysis, conducted to determine the exact nature of interaction effect, reveals that the relationship between managerial characteristics and EDI implementation is significantly stronger with a high level of decentralization or management risk position than with a low level.
