With the explosion of internet users, there are many enterprises and organizations that regard the internet as the great marketing superhighway. Although fascination and speculation surrounds the impact of the cyber shopping mall on consumer shopping behavior, there is little empirical evidence underlying all this speculation. This article reports on the critical issues that consumers found salient as they browsed through cyber shopping malls. We gathered consumers’reactions via open-ended survey. We relate the reactions to the factors of tangibility, assurance, responsibility, empathy, and reliability which we had identified from the existing literature on service quality. Two additional questionnaires were administered to translate these factors to the cyber shopping mall context and to explore their relative salience. We also evaluated SERVQUAL and SERVPERF as service quality measures for cyber shopping malls. The results show that SERVPERF seems more promising than SERVQUAL. The results also suggest that cyber shopping mall merchants need to think more about how they perform on the issues known to affect customers’decision making for purchasing. We offer advice for enhancing the design of cyber shopping mall.

There is no doubt that dopamine plays a critical role in the etiopathogenesis of schizophrenia. However, there appeared some limitations in explaining the complex phenomena of schizophrenia. Recent research data suggest that dysfunction in serotonergic system may be involved. Before the dopamine hypothesis of schizophrenia became established, the interest in serotonin(5-hydroxytryptamine, 5-HT) as an etiological substrate of this illness occurred. Recently the importance and extent of 5-HT's involvement in the pathophysiology and mechanism of action of antipsychotic drug is actively investigated. In recent years, therapeutic success of clozapine and risperidones has increased attention on the interaction between the 5-HT and dopamine systems in schizophrenia. This led to the concept of serotonin-dopamine antagonist for antipsychotics. The authors review the evidence for the role of 5- HT in schizophrenia and serotonin-dopamine interaction.

This paper presents an improved escalator dynamic model so as to reflect the experimental observation on the pseudo-resonance affected by load applied. The experimental evidence reveals that backlash of gearbox as well as sag of driving chain are most critical factors to the pseudo-resonance in escalators. The dynamic model effectively reflects vibration characteristics measured in real escalators with respect to different conditions of driving chain and the number of passengers. For validation of the dynamic model developed, numerical results from the model are compared with experimental results. The developed model and its simulation results are used rigorously for the design of escalator systems in enhancing the ride comfort.

Caloglossa species occurs in freshwater streams around Southest Asia. We report it from 2 different riverine sites in Kerala, India. Tetrasporangiate plants were observed in field collections from the Periyar River and Chalakkudy River. The Chalakkudy isolate did not reproduce in culture but the Periyar isolate developed abundant tetrasporangial sori in culture. Many spores were discharged and most were abortive, but some germinated normally, sporelings forming male gametophytes with numerous spermatangial sori and females with many procarps, viable carposporophytes and some nonfunctional (no carpospores) pseudocystocarps. Some carpospores germinated forming new tetrasporophytes. Molecular evidence (28S rDNA and rbcL) placed the Indian specimens close to C. beccarii and C. fluviatilis. Considering the freshwater habitat and morphology of vegetative thalli (blade shape, rhizoid arrangement, and number of rhizoid filament per cell), the Indian specimens should be assigned to C. beccarii.

Background: Various functional factors should be incorporated during assessment and intervention for patient rehabilitation. Stable respiratory function is one of required factors for functional restoration. To maximize respiratory physical therapy intervention outcome, it is required to understand clinical features of respiratory diseases and physical therapy approaches. Methods: Previous studies were systematically reviewed through computerized search. Methodological qualities of selected studies were evaluated and the levels of recommendations were determined. Results: Assessment for respiratory pattern and thoracic mobility is of importance to improve cardiopulmonary fitness during physical reconditioning. Application of optimal therapeutic protocol can increase thoracic mobility and respiratory function. Interdisciplinary communication is critical during rehabilitation for respiratory patients. Health care provider should have professional knowledge and experience for cardiopulmonary fitness and obligation to endeavor for patients' respiratory rehabilitation. It is necessary to standardize therapeutic intervention, and rehabilitative respiratory exercise should be applied to confirm the effects of intervention. Conclusion: Respiratory diseases that may reduce patients' quality of life and cardiopulmonary fitness should be resolved through physical therapy approaches. Through conducting research, effect of evidence-based and patients' function-oriented intervention can be determined.

Purpose - Micro-finance institutions (MFIs) are critical to Vietnam's quest for poverty alleviation among the poor in the rural and agrarian communities. The current study attempts to investigate the impact of microfinance outreach programs undertaken by formal and semi-formal MFIs in Vietnam targeting the poor rural and agrarian communities. Research design, data, methodology - An enquiry was made as to whether the poor and rural communities accessed the micro credit offered by Government supported MFIs and NGOs through their microfinance outreach programs. Furthermore, the current study attempted to explore if the current mode of operations adopted by MFIs in Vietnam is sustainable. Results -The findings indicate that significant progress has been made in Vietnam to alleviate poverty among the poor rural communities through micro finance outreach programs. Conclusions - There are also pointers of MFIs sustainability in Vietnam. However, it still remains to be seen if the current sustainability pointers are long lasting without government subsidies or some international organizations financial support to microfinance outreach programs.

On the basis of morphological and functional studies, it is now established that there exist multiple motor representation areas in the frontal lobe of subhuman primates. Recent development of analysis on cerebral critical organization in human subjects, utilizing novel techniques of PET and MRI, provides evidence of corresponding motor areas. Each area has its unique sources of inputs from the thalamus and from other parts of the cerebral cortex. To understand functional roles of these multiple motor areas, it is necessary to study neural activity while subjects are performing a variety of motor tasks. In view of high accuracy in spatial and temporal resolution, the analysis of single cells in relation to specific aspects of motor behavior remains to be a powerful research technique. It is with this technique that a number of novel concepts on functional roles of multiple motor areas have been proposed.

The technological innovation has been recognized critical factors of productivity of firms and key contribution of improvement of firm performance for a long time. Many researchers have investigated the relationship between R&D investment or patents as a proxy of innovation and productivity. But there were some problem such as lacking of data and ambiguity of innovation definition. So, previous literatures have some difficulty in reliability of analysis for using only survey data. And investigating the relationship R&D and other factors is very difficult. Therefore, this paper tries to investigate and analysis the relationship between innovation and performance of Korean manufacturing firms. Using KIS2002(Korean Innovation survey 2002) which was based on Oslo manual in 2002 and financial data of firms (KISINFO), I will intend to establish the reliability of multiple analysis. In detail, I will investigate whether the innovation input have effect on the innovation output, whether the innovation output have effect on productivity for heterogeneity and what factor of innovation environment have effect on the innovation itself.
