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 “product-servicization” vs. “service-productization”. 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 ‘connection’, rather than ‘integration’ 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 ‘integration’ 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 “product-servicization”. Further development of this research could lead to establishing a framework for the Design-led Service-Product Integration.

Department of Energy Engineering (Battery Science and Technology)Bulk-type all-solid-state lithium batteries (ASLBs) using sulfide solid electrolytes (SEs) are considered as a promising candidate to solve the safety issues originating from the use of flammable organic electrolytes. Moreover, several state-of-the-art sulfide solid electrolytes shows extremely high ionic conductivity over 10-2 S cm-1, compared to conventional liquid electrolytes. However, to develop bulk-type ASLBs, it encountered many technical challenges such as huge interfacial resistances between active materials and SEs, high contents of SEs in ASLBs, scalable fabrication and reliable test protocol. To fulfill these requirements, sheet-type ASLBs using a scalable wet-slurry process can provide a breakthrough in the architecture and fabrication of composite structure. The first part of my thesis is sheet-type ASLBs using bendable solid electrolyte films and dry-/slurry- mixed electrodes, which are prepared by wet-slurry process. In the first case, the facile and scalable fabrication of bendable solid electrolyte films reinforced with a mechanically compliant NW-scaffold, which enables the fabrication of free-standing and stackable ASLBs with high energy density and high rate capabilities. For the second case, the comparative study for electrodes fabricated by dry- and slurry- mixing process was performed. The information provides insights for a need to develop well-designed electrode with better ionic contacts and to improve the ionic conductivity of SEs. Pouch-type 80 x 60 mm2 all-solid-state LiNi0.6Co0.2Mn0.2O2/graphite full-cells fabricated by the slurry process show high cell-based energy density (184 W h kg-1 and 432 W h L-1). Furthermore, their excellent safety is also demonstrated by simple tests (cutting with scissors and heating at 110oC). The second part is a reliable electrochemical analysis of sheet-type ASLBs. Even though the well-developed sheet-type ASLBs using sulfide SEs have been demonstrated, their reliable electrochemical test protocols have not been developed. In this regard, in this study, from the in-depth study of ASLBs using novel bulk-type all-solid-state three-electrode cells, even for the cells having thin SE layers, kinetic behaviors of Li-In(-SE) CEs and internal short circuits (ISC) by penetrating growth of Li metal during charging at high C-rates are revealed. In addition, unique durability of LiNi0.6Co0.2Mn0.2O2/graphite or LiNi0.6Co0.2Mn0.2O2/Si-C full-cells upon discharge to 0 V was described. In the last study, the pressure monitoring system for sheet-type ASLBs is demonstrated. The state-of-charge (SOC) values were estimated from volume changes of graphite electrodes in LiNi0.6Co0.2Mn0.2O2/graphite full-cells. The behavior of rearrangement of particles in electrode during cycling is also observed. These results hold great promise for practical sheet-type all-solid-state technology in terms of fabrication and battery architecture as well as provision of in-depth insights into developing reliable electrochemical test protocols.clos

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

Vav1 inhibits RANKL-induced osteoclast differentiation and bone resorption

Vav1 is a Rho/Rac guanine nucleotide exchange factor primarily expressed in hematopoietic cells. In this study, we investigated the potential role of Vav1 in osteoclast (OC) differentiation by comparing the ability of bone marrow mononuclear cells (BMMCs) obtained from Vav1-deficient (Vav1−/−) and wild-type (WT) mice to differentiate into mature OCs upon stimulation with macrophage colony stimulating factor and receptor activator of nuclear kappa B ligand in vitro. Our results suggested that Vav1 deficiency promoted the differentiation of BMMCs into OCs, as indicated by the increased expression of tartrate-resistant acid phosphatase, cathepsin K, and calcitonin receptor. Therefore, Vav1 may play a negative role in OC differentiation. This hypothesis was supported by the observation of more OCs in the femurs of Vav1−/− mice than in WT mice. Furthermore, the bone status of Vav1−/− mice was analyzed in situ and the femurs of Vav1−/− mice appeared abnormal, with poor bone density and fewer number of trabeculae. In addition, Vav1-deficient OCs showed stronger adhesion to vitronectin, an αvβ3 integrin ligand important in bone resorption. Thus, Vav1 may inhibit OC differentiation and protect against bone resorption

ADADA 2016 14TH international Conference for Asia Digital Art and Design Association - Relationship between perceived value in Omni-Channel Shopping and repurchase intention

Along with the development of ICT, the distribution strategy of existing companies has been changing to the ‘Omni-Channel’ strategy. According to the diversification of distribution channels, the value of customer shopping has also been changing. Consumers that shop within various distribution channels want to acquire benefits through new and diversified experiences. Thus, it is important to perform studies on whether continuous purchase is possible by continuing from values that are being satisfied by certain elements of the Omni-Channel by grasping the cognition of consumers. This study identifies the characteristics of Omni-Channel consumption, perceived usefulness through the ease-of-use by consumers, and relationships with repurchase intention. This study provides a theoretical basis to activate the Omni-Channel which may satisfy the demand of consumers by setting causal relationship between each element by conducting a survey

Generation of subspecies level-specific microbial diagnostic microarrays using genes amplified from subtractive suppression hybridization as microarray probes

The generation of microarray probes with specificity below the species level is an ongoing challenge, not least because the high-throughput detection of microorganisms would be an efficient means of identifying environmentally relevant microbes. Here, we describe how suppression subtractive hybridization (SSH) can be applied to the production of microarray probes that are useful for microbial differentiation at the subspecies level. SSH was used to initially isolate unique genomic sequences of nine Salmonella strains, and these were validated in quadruplicate by microarray analysis. The results obtained indicate that a large group of genes subtracted by SSH could serve together, as one probe, for detecting a microbial subspecies. Similarly, the whole microbial genome (not subjected to SSH) can be used as a species-specific probe. The detailed methods described herein could be used and adapted for the estimation of any cultivable bacteria from different environments

Influence of Oryzanol and Ferulic Acid on the Lipid Metabolism and Antioxidative Status in High Fat-Fed Mice

The comparative effects of oryzanol and ferulic acid on the lipid metabolism and antioxidative status of high fat-fed mice were investigated. The mice were given a diet containing 17% fat (HF), supplemented with oryzanol (HF-O) or ferulic acid for 7 weeks. The control mice (NC) were fed with normal diet. The HF mice exhibited increased body weight gain, plasma and hepatic total cholesterol and triglyceride concentrations, and lipid peroxidation rate, and reduced high-density lipoprotein cholesterol level. In general, they also showed lower hepatic antioxidant and higher lipid-regulating enzymes activities relative to that of NC group. Addition of oryzanol or ferulic acid in the diet counteracted these high fat-induced hyperlipidemia and oxidative stress via increased faecal lipid excretion and regulation of antioxidant and lipogenic enzymes activities. This study illustrates that oryzanol and ferulic acid have relatively similar hypolipidemic actions and could be effective in lowering the risk of high fat diet-induced obesity
