This paper represents an exploratory effort to test empirically the contingent relationships between the contextual variables, such as user task characteristics and personality, and the information characteristics of Accounting Information Systems (AIS), and to prove the effects of influence factors on the increase of personal office productivity. In this study, it was suggested that personal office productivity is influenced by the fit between the contextual variables and the information dimensions of ALS. It was also proved that influence factors have a positive effect on the increase of personal office productivity.

This paper characterizes the optimal reciprocal trade policy in the environment of Melitz (2003) with firm productivity heterogeneity. In particular, without making parametric assumptions on firm productivity distribution, this paper derives the optimal degree of reciprocal tariff reductions that maximize the world welfare. A reciprocal import subsidy raises the industry productivity, lowering aggregate price; a reciprocal import tariff helps correct the markup distortion, increasing nominal income. With all the conflicting effects of import tariffs on welfare considered, the optimal degree of reciprocity in multilateral tariff reduction is shown to be free trade.

The ongoing debate over IT productivity has revealed paradoxical effects of IT. This study proposes that IT business value is paradoxical structured. IT impacts are not easy to generalize according to one perspective or paradigm. This study assumes multiplicity in the phenomenon of IT value and explores effects of these multiple interpretations. The study seeks to understand organizational performance. Hypotheses are developed to test the relationship between competing interpretations of IT value and organizational performance. The purpose of this study is to determine whether or not senior managers perceive IT value on the basis of divergent managerial value frames.

This study tries to analyze how TPM works in domestic manufacturing industry by estimating two-stage model. First stage tests the effects of five TPM-factor variables (TFV : (1) Small group activity & Autonomous maintenance, (2) Education & Training, (3) Planned maintenance, (4) improving effectiveness of each piece of facility (5) Safety & Environment) to two TPM-performance variables. Second stage tests how two TPVs affect the industry's productivity level. By combining these two stages, this study uses a model to explain how TPM, represented by TFVs, works to improve productivity via TPVs. Multivariate and univariate regression and correlation analyses were peformed. It is shown that five TFVs works in two different ways to improve the industry's productivity level. In the second stage, overall equipment effectiveness has relatively more significant effects to the productivity level.

Interests on collaborative research and academic relationship among researchers have been increased. Collaborative researchers can maximize productivity, time and cost savings, and reduce the risk of research. An empirical study on the research productivity of co-authors' network and review efficiency of the reviewer network was conducted based on co-author networks and reviewer networks in Korea Society of IT Service. This study aims to find the characteristics of the co-author and reviewer networks, and to analyze research productivity and review efficiency in order to draw some implications. The meaning of interactions among professional groups was analyzed. Research productivity index was calculated using 728 authors' papers submitted to the society. In order to verify the effects of indicators of social network analysis on research productivity and review efficiency, correlation and regression analyses were used. As a result, the indicators of network centrality did not affect the review efficiency, but affect the research productivity.

This study was conducted to investigate the different effects of ectomycorrhizal fungal (ECMF) species on the growth of seedlings of Pinus densiflora, and the effects of ECMF diversity on plant productivity. A total of five species of ECMF were isolated from root tips of pine seedlings collected from Mt. Songni and used as inocula. Pots containing pine seedlings were inoculated with either a single ECMF species or a mixture of five ECMF species. All of the seedlings formed ECM on their roots except for the control plants. The pine seedlings' growth responses varied by the different ECMF species. Also, pine seedlings inoculated with a mixture of five ECMF species showed the highest growth response. The results of the study suggest that the colonization of diverse species of ECMF will increase plant productivity, and the selection of suitable ECMF species could be an important factor for plant growth.

산업부문에서 '저탄소 녹색성장'의 달성 가능성은 기존 화석연료 사용의 의존도를 줄이는 것이 장기적으로 산업 생산성의 향상으로 이어질 수 있느냐에 달려 있다고 볼 수 있다. 본 연구에서는 국내 제조업을 대상으로 에너지절약시설에 대한 투자가 산업 생산성에 미치는 장단기 파급효과를 분석하는 이론적 모형을 제시하고 계량분석기법을 통하여 통계적 유의성 유무를 검증하였다. 에너지절약시설에 투자할 경우 단기적으로는 투자지출이 늘어나 생산비용이 증가하는 '측정효과'와 기술혁신을 위한 신규투자가 지연되는 부(負)의 '실질효과', 장기적으로는 에너지집약도가 개선되어 생산비용이 절감되는 정(正)의 '실질효과' 등이 나타날 수 있다. 산업 생산성의 변화를 설명하는 데 있어서 에너지절약시설 투자규모의 내생성 문제를 해결하기 위하여 2SLS 회귀분석을 실시하였다. 생산액 대비 에너지 투입비용이 상대적으로 높은 제조업 5개 부문을 대상으로 1982년~2006년까지의 연도별 자료를 사용하여 에너지절약시설 투자의 생산성 파급효과 여부를 검증한 결과 화학제품산업을 제외하고 4개 부문에서는 해당 추정계수의 통계적 유의성이 기각되었다. 화학제품산업의 경우 부(負)의 '실질효과'가 정(正)의 '실질효과'를 압도하며 에너지절약시설 투자비용 대비 에너지비용 절감효과는 상대적으로 미미한 것으로 나타났다.

The purpose of this study is to analyze the effects of the health information system on the productivity and behavioral aspects of health workers as well as quality of services to the visitors using the Vaccination room at the Kwon Sun Ku health center located in Suwon city as a study subject. Three survery were conducted to measure the changes in productivity and adoptation process(knowledge, attitude, activity, and satisfaction) of health workers over time during the period of 20 months. In addition, the effects of the information system on the quality of services to the visitors were also masured 7 months after the 3rd survey by comparing the quality of services between the study health center and the similar health center as a control group. The following results were obtained. First, productivity of health workers has improved over time as they became familiar with the system. Second, knowlege and activity did not significantly changed, but attitude score unexpectly decreased in the second survey. This may be due to an effect of intensive training prior to the first survery. Third, quality of services for the study center was better than other health center. While the health information system had positive effects on the productivity as well as the adoptation process, there are several limitations to establish a causal effect relationship between the two variables. For example, the system has kept modified since its development to meet the changing needs of the workers, and this may affect the productivity more than the adoptation process. Furthermore, since the study subject was only one health oenter, it lacks representativeness to generalize the study findings. Therefore, more health centers should be included in the study to solve such problems in the future.

Purpose: Nursing informatics competency is used to manage and improve the delivery of safe, high-quality, and efficient healthcare services in accordance with best practices and professional and regulatory standards. This study examined the relationship between nursing informatics competency (NIC), nursing care left undone, and nurse reported quality of care (NQoC) and nursing productivity. A path model for their effects on nursing productivity among clinical nurses was also established. Methods: Data were collected using structured questionnaires answered by 192 nurses working in a tertiary hospital located in J city, Korea, and analyzed using SPSS/WIN 23.0 and AMOS 21.0 program. Results: The fit indices of the alternative path model satisfied recommended levels χ² = .11 (p = .741), normed χ² (χ² /df) = .11, SRMR = .01, RMSEA = .00, GFI = 1.00, NFI = 1.00, AIC = 18.11. Among the variables, NIC (β = .44, p < .001), NQoC (β = .35, p < .001) had a direct effect on nursing productivity. Due to the mediating effect of NQoC on the relationship between NIC and nursing productivity, the effect size was .14 (95% CI .08~.24). Meanwhile, nursing care left undone through NQoC in the relationship between NIC and nursing productivity, has a significant mediation effect (estimate .01, 95% CI .00~.03). The explanatory power of variables was 44.0%. Conclusion: Education and training for enhancing NIC should be provided to improve nursing productivity, quality of care and to reduce missed nursing care. Furthermore, monitoring the quality of nursing care and using it as a productivity index is essential.
