Business Process Change(BPC) is regarded as a salient factor to improve an organizations' efficiency in the current fast-changing business environment. Despite the tremendous popularity and great potential, the field of BPC adoption is littered with remarkable failures. Consequently, there have been many studies that have tried to identify the environmental factors that lead to successful BPC. However, most of them have not considered the effect of the interaction between the environmental factors on BPC success. According to Klempa(1995), the fit between environmental factors of a company may have the impact on its BPC success. Under this background, this paper empirically examines the effects of the fit between the type of BPC and the organization's culture on the success of BPC. Organization's cultures, organizational learning, as well as knowledge sharing are the dominant causes that have impact on the innovation characters of organization. Whether an organization has safety-oriented homogeneous culture or it has the change-oriented heterogeneous culture may have impact on its implementation of BPC. Also the implementation of BPC may be affected by whether the organization adopts the improvement project which accompanies only small changes or it adopts the innovation project which leads to critical changes. Thus, we analyzed the effect of the fit between the organization's culture and its BPC type on BPC success by using the survey data collected from the companies that have adopted BPC. The findings presented in this paper show that the organization having heterogeneous culture practicing innovation project and the organization having homogeneous culture practicing the improvement project resulted in the excellent BPC success.

Energy-saving is one of important issues in multi-family housing projects in South Korea. According to the study by Yu et al. (2002), the balcony conversion causes energy loss approximately one and a half times. Therefore, it is important to select the economical glass type in the balcony window. In order to identify the most economical glass type of balcony conversion in multi-family housing projects, the most typical type of the multifamily housing projects in the metropolitan area was selected as a candidate project. The selected candidate project has been simulated using ENERGY-10 program to estimate the heat load by the different five types of glasses as well as their life cycle cost analysis (LCCA) using present worth method. Finally, sensitivity analysis has been conducted to determine the most economical glass types under a different discount rate (interest rate) and service life of building.

Background: The modelling of lactation curve provides guidelines in formulating farm managerial practices in dairy cows. The aim of the present study was to determine the suitable non-linear model which most accurately fitted to lactation curves of five lactations in 134 Gir crossbred cows reared in Research-CumDevelopment Project (RCDP) on Cattle farm, MPKV (Maharashtra). Four models viz. gamma-type function, quadratic model, mixed log function and Wilmink model were fitted to each lactation separately and then compared on the basis of goodness of fit measures viz. adjusted $R^2$, root mean square error (RMSE), Akaike's Informaion Criteria (AIC) and Bayesian Information Criteria (BIC). Results: In general, highest milk yield was observed in fourth lactation whereas it was lowest in first lactation. Among the models investigated, mixed log function and gamma-type function provided best fit of the lactation curve of first and remaining lactations, respectively. Quadratic model gave least fit to lactation curve in almost all lactations. Peak yield was observed as highest and lowest in fourth and first lactation, respectively. Further, first lactation showed highest persistency but relatively higher time to achieve peak yield than other lactations. Conclusion: Lactation curve modelling using gamma-type function may be helpful to setting the management strategies at farm level, however, modelling must be optimized regularly before implementing them to enhance productivity in Gir crossbred cows.

Although extracellular $Ca^{2+}$ entry through the voltage-dependent $Ca^{2+}$ channels plays an important role in the spontaneous phasic contractions of the pregnant rat myometrium, the role of the T-type $Ca^{2+}$ channels has yet to be fully identified. The aim of this study was to investigate the role of the T-type $Ca^{2+}$ channel in the spontaneous phasic contractions of the rat myometrium. Spontaneous phasic contractions and $[Ca^{2+}]_i$ were measured simultaneously in the longitudinal strips of female Sprague-Dawley rats late in their pregnancy (on day 18 ${\sim}$ 20 of gestation: term=22 days). The expression of T-type $Ca^{2+}$ channel mRNAs or protein levels was measured. Cumulative addition of low concentrations (< 1 ${\mu}M$) of nifedipine, a L-type $Ca^{2+}$ channel blocker, produced a decrease in the amplitude of the spontaneous $Ca^{2+}$ transients and contractions with no significant change in frequency. The mRNAs and proteins encoding two subunits (${\alpha}$ 1G, ${\alpha}$ 1H) of the T-type $Ca^{2+}$ channels were expressed in longitudinal muscle layer of rat myometrium. Cumulative addition of mibefradil, NNC 55-0396 or nickel induced a concentration-dependent inhibition of the amplitude and frequency of the spontaneous $Ca^{2+}$ transients and contractions. Mibefradil, NNC 55-0396 or nickel also attenuated the slope of rising phase of spontaneous $Ca^{2+}$ transients consistent with the reduction of the frequency. It is concluded that T-type $Ca^{2+}$ channels are expressed in the pregnant rat myometrium and may play a key role for the regulation of the frequency of spontaneous phasic contractions.

본 연구는 연구개발의 성공여부를 판단하기 위하여 경영자들은 어떠한 요인을 중시하는가에 대하여 경험적 연구를 수행하였다. 연구결과 성공을 위한 적절한 판단은 개발하고자 하는 프로젝트의 형태 및 유형에 달려 있음을 발견하면서 개발프로젝트에 대한 재무적 측정의 중요성이 상대적으로 낮다는 점을 주목할 수 있었다. 또한 측정 가능성은 측정지표 선정의 중요한 기준이 되지는 않았다는 점이 선행연구와의 상이한 결과로 오히려 혁신적 수준이 가장 많은 지지를 받음으로 연구개발 활동을 통하여 얼마나 높은 기술혁신이 이루어질 수 있는가에 대한 기술집약적 혁신 및 연구개발 활동이 강조되고 있음을 제시한다. 아울러 평가자의 역할이 판단에 영향을 미칠 것으로 나타나 평가자의 역할 또한 간과해서는 안 될 요인으로 제안하는 바이다. 본 연구를 통하여 향후 정부주도 지원사업에 있어 사업성에 대한 기대가 높은 것은 사실이나 기술적 요소에 대한 지원정책의 가속화가 요구되어 정부지원사업과 연구개발주관기업의 성과관리에 기여할 수 있을 것으로 기대한다.

One of the main concerns of the present age, is attending to the issue of sustainability that in recent decades, the concept of it has grown in terms of recognition and importance. Sustainability have defined further the development of the welfare and living standards of the present generation, without the lives of future generations is at stake. One of these tasks of the business is project management and today, "green or sustainable project management" as one of the most important global trends of project management have been identified. The issue of present study was to investigate the relationship of sustainability factors with success of a project. The population of the research consists of directors of oil and gas in the South Pars region including 150 people that according to Cochran formula, the number of samples were obtained 108 people. In this study, data collection was conducted based on a structured questionnaire that from a sample set of questions was used for sustainability impact on 6 scale of project management success. For this purpose, the whole five-item Likert has been used. Also for statistical analysis, PLS software was used. The results of path analysis at confidence level of 95%, showed a significant relationship exists between "sustainability factor" and "project success criteria." Since the correlation coefficient is positive, so this type of relationship is positive. Thus all the hypotheses at confidence level of 95 percent was confirmed and it became clear that there is a significant positive relationship between "sustainability factors" and "project success criteria."
