Design Opportunities in Service-Product Combined Systems
This paper aims to examine recent research issues related to the integration of service and product in view of industrial design. Further, it attempts to identify new opportunities for further research regarding âproduct-servicizationâ vs. âservice-productizationâ.
In the continued efforts to provide the users with fuller experiences, one major trend is the blending of products and services.
Much existing research seems to either present cases or propose frameworks regarding the âconnectionâ, rather than âintegrationâ between products and services. Broadly, two major approaches seem to exist in this area: 1. product-servicization, 2. service-productization. The former generally indicates adding more services to existing products, whereas the latter generally refers to making services tangible and/or visible in the form of a product. However, findings of an extensive literature search conducted for this study suggest one important deficiency in dealing with service issues around the product: the âintegrationâ between the actual product design and service elements for supporting new service-product system. That is the rationale behind this research, an attempt to investigate the possibility for the integration of product design and service factors which could be embedded in the design of product itself in new service-product system.
This paper is largely based on qualitative research. New design research opportunities are identified by qualitatively analyzing relevant literature, synthesizing the information and presenting some cases to support the main argument of the research.
Design-led Service-Productization is not, and should not be re-arranging deck chairs on the Titanic. Rather, it should bring practical and tangible design issues related to new service-product system. Findings suggest that this approach could provide a new model of new product development integrated with a service scheme, which is a more proactive approach than âproduct-servicizationâ. Further development of this research could lead to establishing a framework for the Design-led Service-Product Integration.

Does Firm Volatility Affect Managerial Influence
The aim of this paper is to develop and test a new theory that firm volatility can affect managerial output. Theoretical underpinnings for the hypothesis are developed and drawn from the existent literature. This hypothesis is then tested with data from 3,296 companies listed on the Korea Stock Exchange (KSE) from 1999 through 2008. The theory and the empirical results in this paper suggest that the effect of managers on firm performance differs with the degree of firm volatility. We find that a higher ratio of directors from top-ranking academic institutions leads to an increase in market value when firms suffer high volatility. Moreover, these results suggest that the interaction between executive characteristics and firm volatility has important consequences for firm performance. The findings expand our view of firm volatility to previous studies. Keywords Volatility, Managerial Influence, Firm performanc
Interfacial architecture for extra Li+ storage in all-solid-state lithium batteries
The performance of nanocomposite electrodes prepared by controlled ball-milling of TiS2 and a Li2S-P2S5 solid electrolyte (SE) for all-solid-state lithium batteries is investigated, focusing on the evolution of the microstructure. Compared to the manually mixed electrodes, the ball-milled electrodes exhibit abnormally increased first-charge capacities of 416 mA h g-1and 837 mA h g-1 in the voltage ranges 1.5-3.0 V and 1.0-3.0 V, respectively, at 50 mA g-1 and 30??C. The ball-milled electrodes also show excellent capacity retention of 95% in the 1.5-3.0 V range after 60 cycles as compared to the manually mixed electrodes. More importantly, a variety of characterization techniques show that the origin of the extra Li+ storage is associated with an amorphous Li-Ti-P-S phase formed during the controlled ball-milling process.open1
Electrogenic transport and K(+) ion channel expression by the human endolymphatic sac epithelium.
The endolymphatic sac (ES) is a cystic organ that is a part of the inner ear and is connected to the cochlea and vestibule. The ES is thought to be involved in inner ear ion homeostasis and fluid volume regulation for the maintenance of hearing and balance function. Many ion channels, transporters, and exchangers have been identified in the ES luminal epithelium, mainly in animal studies, but there has been no functional study investigating ion transport using human ES tissue. We designed the first functional experiments on electrogenic transport in human ES and investigated the contribution of K(+) channels in the electrogenic transport, which has been rarely identified, even in animal studies, using electrophysiological/pharmacological and molecular biological methods. As a result, we identified functional and molecular evidence for the essential participation of K(+) channels in the electrogenic transport of human ES epithelium. The identified K(+) channels involved in the electrogenic transport were KCNN2, KCNJ14, KCNK2, and KCNK6, and the K(+) transports via those channels are thought to play an important role in the maintenance of the unique ionic milieu of the inner ear fluid
