To date, the implementation and adoption of new manufacturing technologies has been retarded despite their technical advances and strategic virtues such as flexibility and synergy effect. This phenomenon is partly attributable to the lack of commensurate development and widespread dissemination of adequate selection and justification procedures. Many strategically vital automation projects have been rejected and/or seemingly promising proposals have turned out to be fiascos since the justification process has been solely based on the traditional capital budgeting or engineering economy methods. As the degree of system automation/integration increases, a variety of benefit/cost attributes, both quantitative and qualitative, should be taken into account and more comprehensive and analytic justification methods should be applied in the justification process. This paper points out the distinct characteristics of advanced technologies and presents an illustrative set of procedures that can be used in the justification process. It outlines the algorithmic structure of each procedure and also describes the advantages/disadvantages of each procedure and the conditions under which it is most appropriate to employ. The selection of appropriate justification technique is situation-specific. In general, it is recommended that more complex and sophisticated procedures be used as the degree of integration increases. Nonetheless, traditional procedures may be used as well to make in-depth analyses of the local impact.

Commercial banks play an important role as the main source of funding in the transition process of Vietnam as a market economy. As a result, enhancing the efficiency and productivity of Vietnamese banks can decrease the lending cost for individuals and enterprises. This study is to measure and analyze the productivity change of Vietnamese banking system in different ownership cohorts and sources of this change during the period of restructuring (2011-2019). The Hicks-Moorsteen total factor productivity index is utilised to measure the productivity change and to identify the sources of this change. For an empirical analysis, the data of 28 Vietnamese commercial banks from 2011 to 2018 is collected from their financial statements including balance sheets and income statements. The results show an increase of Vietnamese bank productivity due to the technological progress. While foreign and joint-venture banks are the most advanced cohort, state-owned banks have the lowest rate of productivity growth. The restructuring program negatively impacts scale efficiency and this measure attributes to a decline in the overall efficiency of the banks. We also found that state-owned commercial banks are the most efficient group in the sense that they can achieve the maximal level of revenue from a given amount of expense.

Because the 'image' is the 'reality' in this era, there are the characteristics dematerialized between reality and non-reality in the contemporary architecture. These are promoting individualization, differentiation and multi-layered time with the development of electronic technology. This trend emphasizes the importance of imagines that are not only homogenized, simultaneous but also overlapped, multi-layered, discriminatory. Perspectives and essential characteristics of the architectural skin are changing in terms of the technical and social awareness and that means the skin has features as a complex body. Recently as an imagine creator, the architectural skin make form of media boundaries reflecting the various relationships between the observer and the external environment and also, the interior space become another sensory skin by removing the boundaries of the internal and external. It is important that making an identity of the architecture defined by the media or the imagine as well as the importance of space in architecture. These changes of skin make the third space based on the viewer's imagination and show the potential of new architectural skin with the expansion space by blurring the boundary between reality and illusion. It occurs to the diversity of the architectural skin with the identity. It will more diversified and be recognized immediately and sensibly through the interface attributes in contact with the city directly. In addition, it is more important that the skin become a unified body related with urban, social and cultural context.

Our research seeks to assess the influence of nuclear energy technology on carbon emissions in the top 10 European economies comprising the topmost nuclear energy R&D budget (France, Germany, Russia, the Netherlands, the UK, Finland, Spain, Sweden, Italy, and Switzerland). Unlike prior investigations predominantly relying on panel data methodologies without considering the distinctive characteristics of each economy, our study employs the advanced 'Quantile-on-Quantile' approach. This novel methodology enables us to investigate the interactions between variables within each unique nation, thereby improving the precision of our analysis. As a result, the study provides a thorough global perspective, revealing nuanced findings pertinent to each economy's specific attributes. Our outcomes demonSstrate a positive interconnection between nuclear energy technology and carbon emissions across various quantiles in our analyzed nations. Additionally, the study highlights diverse patterns in these associations within individual economies. These findings emphasize the significance of policymakers performing comprehensive measurements and devising effective strategies to monitor fluctuations in nuclear energy technology and carbon emissions.

There exists a general consensus in Korea that patients tend to concentrate in large hospitals and this tendency is partly responsible for inefficiency in health services. The process of choosing a medical care provider for health care services and evaluating the provider after utilization seems to involve many diverse factors to become very complex. Therefore a systemsatic study is needed to achieve sufficient understanding of the proeess. For this point of view, this study investigates patient's selection of medical care institution for delivery care services and their evaluation of the institution after delivery. In more specific, the objectives of the study are twofold: 1) to identify the factors associated with expectant mothers' choice of type of medical care institution for delivery among tertiary hospitals, general hospitals, small hospitals, and clinics: and 2) to understand the factors affecting patient evaluation of the medical care institution after delivery. The data used for the analysis were collected through face-to-face interviews with those women who had childbirth during the period from January 1, 1996 to the date of interview in February 1998. The survey was conducted using preqared structured questionnaire in Seoul. The sample was drawn from each of arbitrarily defined four regions of Seoul, Northeast, Northwest, Southeast and Southwest, in proportion to the number of births reported in 1996 in each of them. The distribution of the interviewed women by educational level was made similar to that of mothers of new babies reported in 1996. The sample size was planned to be about 300, but ended up with analytical sample of 319. Major conclusions emerged from the analysis can be summarized as follows: 1) Large hospitals were evaluated as much better for technical quality than other types of institutions, whereas they were compared similar to or worse for other attributes. And it was found that technical quality of care is considered as the most important condition of medical care institution for delivery, while the amount of direct cost is considered as the least important one. Taken together, the utilization of large hospitals is not likely to decrease even though they cannot give satisfaction to patients in other aspects than technical quality. 2) The activeness in the search for information affected the respondents' evaluation of medical care institutions, which would influence their later decision or recommendation to other persons as to the choice of source of health care services. Therefore, increased efforts should be directed to improving availability of useful and correct information for patients in relation to the utilization of health care services. 3) Since the findings of this study were obtained from the analysis of delivery care services, their applicability to other kinds of services may be limited. Thus it would be useful to conduct a comparative study of several kinds of services explicitly taking into account the characteristics of those services in the analysis.

In the early part of rice growth, root volume primarily limits the amount of plant-accessible nitrogen (N). Therefore, knowledge of the root development is important for modeling N uptake of rice. The timing when the volume of rhizosphere cover the whole soil is also important to carry out timely top dressing. However, information about initial root expansion and associated N uptake is limited due to intrinsic technical difficulties in assessing below-ground processes. Some studies, however, showed a close relationship between below-ground root and above-ground leaf development, suggesting a possibility that above-ground attributes could serve as surrogates for the root processes. In this study, we investigated the relationship between below-ground and above-ground development of rice. Field experiments were conducted where we cultivated Koshihikari (a leading cultivar in Japan) for four different cropping schedules in 2012. In 2016, Gimbozu (HEG4) and three flowering time mutant lines of Gimbozu (X61 (se13), HS276 (ef7), DMG9 (se13, ef7)) were examined for a single season. Experiments were performed with three replications in a completely randomized design. We monitored ammonium-N concentration ([NH4+-N]) in soil solution by repeatedly taking samples from a porous tubing (10-cm long) vertically inserted at the most distant point from surrounding rice hills. Samples were taken in triplicate (= triplicate tubes) and every three days from transplanting in each experimental unit. For above-ground attributes, leaf area index (LAI) was measured in 2012, whereas soil coverage ratio was estimated by image processing in 2016. Results showed that [NH4+-N] increased gradually after transplanting and then rapidly decreased from a certain day. This distinct drop in [NH4+-N] informed us the timing at which the rice root system reached the point of porous tubing and thus essentially covered the whole soil volume. The LAI at the dropping point was about 0.43 regardless of the cropping schedules in 2012 experiment. In 2016, the coverage ratio at the N dropping point was within the range of 0.12 to 0.19 for four genotypes having different growth durations. In addition, the coverage ratios at seven weeks after the transplanting showed a good correspondence to LAI across the four genotypes. We therefore conclude that both LAI and coverage ratio may serve as robust indicators for root development and might be useful to estimate the timing when the root system fully cover the soil volume. Results obtained here will also contribute to develop models that can predict not only above-ground canopy development but also associated below-ground processes.
