In the construction industry, IT based information system has been diversely applied to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced to gather information in construction site, the effect of the IT device is limited, because of bringing about additional works of engineer. In this paper, we proposed a defect management system which is based on handwritten document digitalization framework for introducing applicability of new IT device, digital pen. By the proposed system, we can effectively gather and input defect information to defect management system by using digital pen and paper like conventional way. Applying the data gathering device, digital pen to defect management, it is able to increase productivity by improving work process, building up and utilizing defect information database of good quality.

Development of village chicken production can be a sustainable way of helping to meet the welfare needs of rural populations and raise their living standards. There is a dearth of information on research conducted to characterize, understand and develop the village chicken production systems in Zimbabwe. This review focuses on constraints, opportunities and research needs for the improvement of village chicken productivity in Zimbabwe. Village chicken production in Zimbabwe is extensive and dominated by indigenous chickens that exhibit remarkable adaptation to local environments. The multitude functions of village chickens, which include the provision of high quality protein meat and eggs, cash through sales and socio-cultural roles, are discussed in detail. Human gender aspects in village chicken production are highlighted. The factors that hamper village chicken productivity are reviewed together with opportunities and research needs. The major constraints include shortage of feed, poor health and housing management. Any improvements in these constraints may lead to sustainable increase in village chicken productivity.

The paper aims to investigate whether foreign direct investment (FDI) has positive effect on the labour productivity in Vietnam. Labour productivity is the elemental determinant of a country's development level in long-term. In recent years, although increasing consistently, labour productivity of Vietnam remains low in comparison to other South East Asian countries. To identify the direction of effect and the level of effect of FDI and human capital on the labour productivity of Vietnam, Autoregressive Distributed Lag (ARDL) model was used to examine the effect of FDI and human capital on labour productivity in Vietnam from 1986 to 2014. The results of bounds test confirm the existence of cointegration among the variables. Further, the Toda and Yamamoto Granger causality test affirms that there is unidirectional causality running from foreign direct investment and human capital index to labour productivity. The empirical results provide strong statistical evidence that foreign direct investment and human capital has a positive impact on labour productivity in Vietnam in long-term. These findings imply that workers are expected to further improve their knowledge, skills and that policy-maker should establish concrete plans to increase human capital. Results from this study provide suggestion necessary for Vietnam to achieve sustainable development.

Measuring the process of construction operations for productivity improvement remains a difficult task for most construction companies due to the manual effort required in most activity measurement methods. There are many ways to measuring the process. But past measurement methods was inefficient. Because they needed a lot of manpower and time. So, this article focus on the vision-based object recognition and tracking methods for automated construction. These methods have the advantage of efficient that human intervention was reduced. Therefore, this article is analyzed the performance of vision-based methods in the construction sites and is expected to contribute to selection of vision-based methods.

최근 대량생산에 기초한 세계 경제의 패러다임이 공급과잉과 개도국 위주의 지나친 양적 경쟁으로 인한 폐해로 인하여 환경악화와 각국간 갈등구조 심화 등 새로운 문제로 분출되면서 이와 같은 외부효과의 내재화와 생산 과정의 투명성, 예측가능성의 글로벌 표준에 입각한 지속가능 경쟁체제에 대한 패러다임이 급속히 확산되고 있다. 특히 제2차 G20정상회의를 계기로 전세계적인 녹색성장을 새로운 패러다임으로 제시한 한국경제에 있어 환경문제는 매우 심각하며, 그 어느 분야보다 친환경적인 녹색생산성에 입각한 지속가능한 국제경쟁력의 강화가 시급한 상황이라 할 것이다. 선진국으로의 진입을 목전에 둔 상황에서 기존의 투입대비 산출량의 극대화를 위한 생산성 향상전략은 그 내재적인 한계가 심각한 상황에 이르고 있기 때문이다. 이를 극복하여 지속가능한 국가경쟁력을 강화하기 위한 핵심적인 의제는 바로 녹색성장을 위한 효율성, 즉 녹색생산성에서 비롯된다고 할 것이다. 이를 위해 기존의 전통적 생산성개념에 환경오염변수를 고려한 방향적 거리함수(directional distance function)와 Malmquist 지수 (ML지수)가 개발되면서 다양한 논의가 진행되었고, 본 연구는 그 가운데에서도 가장 최근에 새롭게 제시된 연구방법론적 특성과 경영환경의 특성을 감안한 총체적 ML지수 (Global Malmquist-Luenberger Index, GML) 연구 모형을 소개하여 환경 보호와 경제개발을 조화롭게 추진하기 위한 녹색생산성의 실질적인 효과를 분석하기 위한 종합적이고도 체계적인 패러다임을 제시하고자 한다.

As expansion of interest income business faces several limitations, non-interest revenue can play a vital role in increasing the net profit margin and the productivity of the assets to sustain the growth rate. This study aims to analyze the Effect level (partial or total) of a bank's size on the relationship between non-interest revenue and the sustainable growth rate of Jordanian commercial banks. Baron and Kenny's methodology (1986) was adopted to test and analyze the effect of non-interest revenue: including the bank's size, on the sustainable growth rate during the period from 2008-2019. Data collection was done for thirteen commercial banks which constituted 100% of the study population. Testing four hypotheses by using Amos program and a regression model to diagnose the partial and total effect of size. Findings indicate that there is a nonlinear relationship between Non-IR and SGR due to the total effect of bank size on the sustainable growth rate. The results of this study is expected to enable the banks to diversify their revenue to support financial performance towards healthy growth without facing additional financial problems. This study adopted a different methodology from the prior efforts, by using the mediation effect role to verify the effect of non-interest revenue.

This study aims at investigating the effects of internal control effectiveness on business survival of food businesses in Thailand through the mediators of productivity improvement and value creation. In this study, 155 food businesses in Thailand are the samples of the study. The results show that internal control effectiveness has a significant influence on productivity improvement and business survival. Productivity improvement critically affects value creation and business survival while value creation is an important determinant of business survival. However, internal control effectiveness has no relationship with value creation. Also, productivity improvement explicitly mediates the internal control effectiveness-business survival relationships. In summary, internal control effectiveness can enhance firms' sustainable competitive advantage, superior performance and long-term survival. Firms need to focus on internal control effectiveness through investing their assets and resources and utilizing their abilities, competencies and capabilities in order to continuously develop and improve their appropriate concepts and characteristics in an organization. Better internal control effectiveness definitely leads to more long-term survival. To generalize the research results, future research needs to collect data from other businesses and industries. Increased response rate of the study is important for future research to verify and confirm the research results.

In the recent, it is gradually important for airport to consider environmental aspects as sustainable development is emerged. ICAO, FAA and individual countries has tried to reduce airport noise and pollution. Thus, the effort is needed to incorporate environmental factor into productivity indicator of airport. Our paper use DEA method with the non-parametric directional output distance function(DDF) to assess productivity of 14 airports in Korea during 2008~2010. In addition to three inputs, two conventional outputs, two undesirable outputs have been considered : noise and air pollution. Results are compared from models that do not include undesirable outputs. Inclusion in the analysis of the undesirable effects of airport operations leads to greater and closer airport's efficiency scores.

This study argues that expanding the multifunctionality of agriculture (MFA) may mitigate existing agricultural problems. To do that this study redefines the concept and scope of the MFA and presents practical tasks to achieve it. Theorizing the MFA begins with the theory of sustainability and first identifies the link between sustainability and MFA. Later, considering the limitations of the existing sustainability theories, we examined where the false linkages leading to the destruction of environmental and social relations originated, and employed the (Re)productivity [(Re)produktivitat] theory in order to obtain alternatives. Research shows that welfare effects of the MFA on humans and the environment are not less than those derived from the agricultural products supplied to the real market, but the values are not recognized. The absence of proper care and compensation is the basis of agricultural problems in Korea. Therefore, this study acknowledges that the MFA is as much worthy as real agricultural production, and insists that appropriate compensation and care should be given to humans (farmers) and nature (agricultural ecosystem) in order to maintain and expand the MFA. In other words, a virtuous cycle between sustainability and the MFA means that the process spreads sustainable farming methods to expand the MFA, forms social consensus on it, and pays fair remuneration for agriculture from the public sector. Transition to such a virtuous cycle requires re-establishing the definition and scope of the MFA, implementing targeting policy, motivating policy targets, strengthening human capacity, and arranging maturity time.
