This paper has explored when implementing SW development project of the IT service corporations, what factors affect its productivity in SW development methodology. The importance of the AHP analysis surveyed from the experts in IT service companies and related committee, was shown in the order of the following processes : 1) Deployment process 2) Management process 3) Establishment process. It is measured the methodology levels of establishment, deployment and management in each project using the survey results collected from project execution members and analyzed the productivity of projects that have been executed within 2 years. Using project methodology level, productivity correlation analysis, and regression analysis, this study confirms that the methodology deployment level brings positive effects significantly to SW development productivity. The significance of this study would be not only to research and analyze SW development productivity using the real project execution data but also to underline the necessities and the importance of steady research, deployment and support for SW development productivity improvement.

Productivity is an important factor of the construction's success and growth. However, compared to the other industries, the study of productivity in the construction industry is still insufficient. Even though the Cast-in-Place piles work is also important in construction process, the research on the productivity is not enough. So, it is necessary for the systematic research on the productivity of Cast-In-Place Piles Work. Therefore, the purpose of the study is to classify lower productivity's cause and find a way to improve these situations. This study will give the checklist for the further study of factoring and improvement of the Cast-in-Place piles work productivity.

Due to the labor-intensiveness, high investment cost, long execution time, frequent change orders, and many stakeholders in a BIM project, a BIM manager is bound to face a lot of risks to make decisions in cost managing process. Since the productivity of a BIM team will affect the execution cost, this study investigates a simple method of assessing the productivity of a BIM team using the working timesheet records of the team. In this research, the productivity of a BIM team is defined as the effective working floor area (in square meters) of BIM uses per labor-time (in man-months) spent by the team. After the applicability of this method is tested by regression analysis using data from 5 real BIM projects in the construction phase, it is found that the simple productivity definition adopted in the method, although easy-to-implement, does not produce a statistically constant productivity value. More research is therefore needed in the future to devise better indicator(s) for assessing the productivity of a BIM team.

Each company is more interested in the productivity to achieve cost reduction and profit maximization through productivity improvement. With this trend, we show the method to measure productivity using TPM(Total Productivity Model) which considers all the input factors of the company instead of using partial productivity such as labor and/or capital productivity We also examine the relation of productivity versus output, profit versus output and profit versus productivity of the case company by actually applying the TPM and suggest the optimal level of profit and output for this company.

Purpose - The purpose of this study is to clarify the mediating effect of profitability and activity in the relationship between productivity and stock return, assuming that the productivity of the company will affect share prices with the parameters of profitability and activity. Design/methodology/approach - The study extracted productivity indicators, profitability indicators, activity indicators, and share price-related indicators from 1999 to 2018 of non-financial enterprises listed on the securities market, and then classified them into three factors: productivity (labor productivity LP, capital productivity CP), activity (TT), and profitability (net profit rate NI, operating profit ratio OI) through the factor analysis method, and analyzed the impact of each factor on the stock return through steps 1 to 3. Findings - The regression analysis shows that productivity has a significant positive effect on the stock return through the full mediating effect of profitability and activity. Research implications or Originality - In a situation where the relationship between productivity and profitability is not clear, this study is meaningful in that it has empirically analyzed that productivity has a positive effect on the stock return by mediating effects of profitability and activity.

The paper aimed to analyze research trends and productivity, targeting papers published for the past 24 years in The Journal of Engineering Education Research, For the research trend analysis, the content analysis was conducted and research productivity of authors was investigated through Lotka's Law. The research subject were 897 papers published on The Journal of Engineering Education Research from 1998 to June 2021. Research findings are as follows. First, the pattern of writing showed that percentage of co-authors over 2 was higher than single author. Second, the authors were most likely to belong the university, followed by government agency, affiliated organization and Research institutes in universities. Third, the flow of records in giving paper showed that the number of continuants has decreased over time and only a few writers have presented their papers. Fourth, the analysis results on the research productivity discovered difference in actual figure and revised, theoretical one, which indicates that Lotka's Law was not applied to The Journal of Engineering Education Research. Based on findings as shown below, we suggested a series of plans to develop The Journal of Engineering Education Research and increase research productivity in future.

Productivity enhancement program of wind tunnel testing has begun at Korea Aerospace Research Institute Low Speed Wind Tunnel (KARI LSWT). A previous test record of a canard airplane model was adopted to examine the current status of wind tunnel testing efficiency. The time consumed to perform testing activities from the model preparation to data collection was broken down and the results were compared with those of the recent Boeing low speed test result. The efforts to improve the wind tunnel productivity consisted of the installation of mini crane underneath of test section, fabricating lift device for image fairings, model configuration changing rigs and the modifications of external balance system. Time reductions for changing strut interface platform and installation of image fairings. These effects showed more than 70% improvement over the previous test time. Integration of the new and modified systems will improve productivity of wind tunnel testing in KARI LSWT.

This research aims at building the conceptual model and proposing concrete ways for raising the ICT productivity of the under-served groups. This research consists of four areas: 1) review and discussion of studies on digital divide issues, 2) theoretical reasoning of the relationship between informatization and productivity, 3) analysis of the present status of information gap between the under-served groups and the general public in Korea, finally 4) proposing the directions of policy making and various concrete ways for reducing information gap and raising the ICT productivity of the under-served groups through facilitating digital inclusion. The model of enhancing the ICT productivity of the under-served groups was theoretically reasoned to include three dimensions which are named as Economy, Efficiency and Effectiveness. The results of this research can be utilized for making policies of not only enlarging the digital opportunity of people in the under-served groups but also raising their income level and quality of life.

This study examines the impact of corporate tax, a fiscal measure along with trade liberalization and research and development on total factor productivity for a panel of 153 industrial firms listed on the Pakistan Stock Exchange over the period 1997-2017. For empirical analysis, we employ the system generalized method of moment estimator. In the first step, we estimate industrial production function and the results reveal that raw material, industrial labour force and energy play vital role in enhancing industrial production. Whereas, industrial capital exerts negative impact on industrial output. We also measured total factor productivity using the production elasticities. In the second step, we examine the impact of corporate tax, trade liberalization and research and development on total factor productivity. The results indicate that higher level of corporate tax exerts negative impact on total factor productivity. The findings reveal that higher corporate taxation discourages industrial firms to undertake research and development thereby exerting adverse impact on total factor productivity of firms. The impact of trade liberalization proxied by average tariff is positive while customs duty and sales tax negatively impact firm-level total factor productivity. These findings provide useful insights for managers, investors and policy makers in Pakistan.
