Purpose - This study examined the effect of tariff cuts on productivity in Korea's manufacturing industries and the effect of initial productivity level before tariff cuts on productivity improvement after tariff cuts. We also attempted to identify whether import-driven or export-driven factors are more important for productivity improvement, especially in low productivity industries. Design/methodology - Since tariff reduction is a policy decision that can affect cross-industry, its impact is spread across all industries beyond the scope of a single firm through the input and output network of industry structure. Accordingly, we proposed a new method to measure the change in productivity to reflect the impact of tariff cuts across industries. Through an Armington CGE analysis, changes in endogenous variables can be directly measured after the exogenous shock of tariff reduction, and the amount of movements in productivity triggered by tariff cuts can also be calculated. We can thus assess the effectiveness of exogenous policy, such as tariff cuts, through the difference between the benchmark and counterfactual values of endogenous variables. Findings - This study confirmed that tariff reduction positively affected productivity improvement in Korea's manufacturing industries. It also confirmed that productivity gains occur in Korea's leading export industries. Finally, greater productivity gains were recorded in the group with additional high-export-share or high-import-share conditions for low productivity industries. These results are, in a limited sense, consistent with the existing studies that emphasize the importance of exports and imports on productivity improvement, especially for low productivity industries. Originality/value - The results of our experiments are different from those of non-CGE studies, which measure the industry-level change in productivity with dummy coefficients, in terms of directly calculating the amount of change in productivity. In addition, we propose that the Armington CGE model is more appropriate than the Melitz CGE model to directly measure the productivity after tariff cuts. This is because the Melitz CGE model assumes the given specific productivity density, which does not change after an overall drop of tariffs. To the best of our knowledge, this approach to directly calculating productivity by reflecting the impact of tariff reduction across industries through CGE analysis, is unprecedented in this literature.

When various construction types of architectural construction are proceeded in order, the reinforced concrete construction is the frame construction which takes up the most important proportion among the construction process. Thus, the analysis of the effectiveness and productivity of the reinforced concrete construction is necessarily needed for smooth performance of construction projects. However, the conventional studies are performing the analysis of the productivity of only part(mould and steel) of the reinforced concrete construction and they have limitation in that they do not propose quantitatively the overall productivity of reinforced concrete construction.

The assembly of the modular housing is an important phase in the construction of pre-fabricated houses. However, the assembly tools that are commonly used in a work site have a disadvantage of decreasing the productivity and the quality. We have developed a exclusive tool for assembling modular parts. The structural stability of the developed tool has been verified in the previous studies. However, the experimental analysis was not conducted. This study analyzed the effect of improving the productivity and quality of the developed assembly tool. The result of the experimental analysis shows improvements in productivity and quality compared to the conventional assembly tool.

안전하지 못한 환경은 작업속도를 지연시키고, 사고 발생 시 대응에 많은 시간을 소요하게 하여 건설공사의 생산성을 크게 저하시킨다. 반면, 지나친 안전관리를 오히려 생산성 저해 요인으로 지적하는 연구도 존재한다. 따라서 건설공사의 생산성을 저해하지 않는 적절한 안전관리는 성공적 공사 수행에 매우 중요한 요인이나, 안전관리와 생산성 상호 간 미치는 영향이 복잡하기에 이에 대한 연구가 부족한 실정이다. 이에 본 연구는 시스템 다이내믹스를 활용하여 안전 관리와 생산성 영향 요인 간의 인과 모델을 구축하고, 효율성 지표를 통한 생산성 측정 및 분석을 진행한다. 이를 통해 과다 인원 투입으로 인한 현장 혼잡도 증가, 비정기적 안전 조치 및 비효율적 초과근무가 실제 작업에 투입되는 시간에 미치는 영향을 분석한다. 안전관리와 생산성의 상호 영향성에 대한 기초 연구인 본 연구의 결과물은, 적정 생산성 확보 가능한 안전관리 방안 수립의 기반으로서 건설산업 경쟁력 제고에 기여할 수 있을 것으로 기대한다.

Purpose : The purposes of this study is twofold: (a) to investigate the effect of job stress and organizational climate on the organizational effectiveness of hospital nurses, and (2) to examine the moderating effect of organizational climate on job stress. Method : Three organizational effectiveness variables(e .g., job satisfaction, organizational committment and group productivity) as outcomes variables were examined. The sample consisted of 602 nurses from 5 general hospitals affiliated university. Data were collected with self-administrated questionnaires and analyzed using hierarchical regression. Results : It was found that: (a) seven job stress variables(e. g., workload, role conflict, schedule, lack of knowledge, conflict with superior, conflict with other personnel and conflict with patients) have negative effect on job satisfaction and organizational committment; (b) organizational climate have positive main effects on job satisfaction and organizational committment; (c) the negative effects of job stress variables on job satisfaction and organizational committment are not moderated by organizational climate. Conclusion : Organizational climate mediates the effects of job stress on group productivity, but the size of the mediating effects was small. Various outcome variables need to be discussed further research.

Most studies of organizational effectiveness previously done, have measured financial performance such as productivity, efficiency or subjective performance such as a commitment, satisfaction, and turnover intention of employees. However, these measurements have limitations to evaluate a organizational effectiveness in recent knowledge information era because evaluation of organizational effectiveness in knowledge-based society needs measurements in various aspects such as financial, customer, internal business process, and learning and growth. The purpose of this study is to overcome these problems and to introduce an appropriate system for evaluation of organizational effectiveness under knowledge management paradigm. In this paper, we suggest a Balanced Scorecard(BSC) as a new measurement standard of organizational effectiveness in a knowledge information era. The balanced scorecard is designed to help firms that have historically overemphasized short-term financial performance. When measuring organizational effectiveness through Balanced Scorecard(BSC) suggested by Kaplan and Norton[31], it is to present the measurement indices that can cover the limitation of the past evaluation indices of organizational effectiveness.

The learning curve has an important effect the growth of corporation. But, in Korea, the study and inference on the learning rate of each industry are unprepared, and so, Korean industires have difficult in productivity and cost. At this point, this study infers the learning rate of the oil industries and investigates the productivity and growth of them. In conclusion, this study presents the direction of the oil industries' development. With the intention of this objects, this study seizes the status which is concerned the total quantity, the operating rate, the plant capacity, the indicators concerning productivity, the investment of R & D and the scales, and then, infers and verifies the relevancy in connection with the learning rate. In the oil industry, the average rate of learning is 65.96% from 1982 to 1994 which the total quantity and the average operation time are used to infer the rate. To observe the low rate within a same period of time, this study takes the consequences that the learning rate is almost indentical with them each year. This steady state is caused by a difference between the employee and the decision maker about the acquirement and assimiliated of technology. When the high-quality technologies posses the environment to applicate in the scene of labor with them, this technology applies to the productivities. As the learning rate increases, the productivity has more effectiveness. The result of analysis about the effectiveness of the learning rate follows that the R & D unfoldes to exist and does not contribute to the growth of the oil industry. To analyze the variables of the growth, such as the learning rate, the investement of R & D, the operating rate and the gross value added to property, plant and equipment, the model is established and examined. The business strategy in the oil industry must be developed to achive the internal growth as well as the external.
