Word-of-mouths (WOMs) are now an important information source for purchase decision. Due to the advance in internet technology, people now can share online their consumption experience, both positive and negative, to others. The WOMs may diffuse to not only their friends but also enormous online users. When consumers dissatisfy the product or service, they may share the dissatisfactory experience to others as WOM, which may bring out discussions for the product or service. The discussions on the negative WOM may help to communicate the negative information to enormous others, which may damage the sale of the product or service. The diffusion and life cycle of negative WOM is an important issue for managers. However, few studies focus on it. Thus, the current study focuses on the discussion pattern and life cycle of negative WOMs by observing the 782 discussion articles in a large online community.

This paper reviews researches related with the elderly caregiving, which hale published during the 1990s. After analyzingthe 29 articles in this field, the major findings are as follows: First, the advantageous position in life chances which is consisted of socioeconomic status and resources tends to reduce th burden for the elderly care. The higher in social status, the more resources older adults have, the more advantageous in controlling their relationship with their children and caregivers. Second, values based on familism is more associated with providing caregiving services for their parents than those of filial piety. Third, the tendency that daughter-in-law takes the role of the primary caregiver suggests a possibility of diminishing her enthusiasm, and finally comes to recognize her role as an enforced one, as time goes by. Fourth, cargiving burden affects the diverse aspects of caregiver's way of life. When the lower class elderly has dementia, caregiving stress and hassle have reached at their peak level. For meeting the needs of reducing the burden for the elderly care, this study suggests community- based approach for the elderly care. This approach attempts to share the caregiving burden with local community. To share the burden means that the boundaries of caregivers does not limit family members, but to expand community. This attempt includes a plan that establishes multipurpose community center which provides comprehensive services and care for the aged. The theoretical rationale of this approach are also discussed.

Cyclomaltodextrinases (CDases), maitogenic amylases, and neopullulanases share highly conserved primary structures and similar characteristics, and are thus classified into the same family. BLAST search has showed that a variety of bacterial strains harbor putative CDase family genes with several well-conserved motif amino acid sequences. In this study, four degenerate polymerase chain reaction (PCR) primer sets were designed for the detection of CDase genes, on the basis of their highly conserved amino acid blocks (WYQIFP, DGWRLD, LGSHDT, and KCMVW). The PCR detection conditions were optimized and the detection specificity of each for the primer sets was tested against the genomic DNAs isolated from 23 different Bacillus-associated species. Consequently, all tested primer sets evidenced successful amplification of specific PCR products in length, which share 55-98% amino acid sequence identity with known and putative CDases. The primers developed herein, therefore, can be applied for the easy and efficient detection and isolation of CDase family genes for the modification of functional food carbohydrates.

When making a yellow layer cake, an existing chemical leavening agent, sourdough starter powder, was used instead of using baking powder in order to produce batter where the acid agent in the baking powder was reduced using baking soda. The control group had the lowest share of the batter and therefore had the highest specific volume. In a test group, the share of SP4 was low and therefore, the specific volume was high. In terms of physiochemical characteristics, the volume, symmetry and uniform index was high in SP4 in the test group. The control group had the highest moisture content followed by SP4. In terms of texture, the control group had the lowest hardness and highest springiness. In the test group, SP4 had the lowest hardness and highest springiness. The result of the sensory evaluation indicates that SP4 had the best taste and flavor. In terms of overall preference, SP4 showed significantly higher preference overall. However, it did not show any significant difference compared to the control group.

The human chromosomes 2, 7, 12 and 17 show genomic homology around Hox gene clusters, is taken as evidence that these paralogous gene families might have arisen from a ancestral chromosomal segment through genome duplication events. We have examined protein data from vertebrate and invertebrate genomes to analyze the phylogenetic history of multi-gene families with three or more of their representatives linked to human Hox clusters. Topology comparison based upon statistical significance and information of chromosome location for these genes examined have revealed many of linked genes coduplicated with Hox gene clusters. Most linked genes to Hox clusters share the same evolutionary history and are duplicated in concert with each other. We conclude that gene families linked to Hox clusters may be suggestion of ancient genome duplications.

BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In manufacturing companies that produce various products with short life cycles, it is very important to manage the BOM of products with various options and versions efficiently. BOM information should be required to share among the departments of engineering, production control, material purchasing, cost management, and shop floor within a manufacturing company. In order to share BOM information efficiently, information system based on WWW(World Wide Web) should be developed. Thus, this paper models and implements Web-based Generic BOM Management System (WGBMS) for management of a number of variant products which are consisted of standard parts under ATO(Assemble To Order) production environment. Also, object-oriented methodology was used to model a generic BOM and phases of navigational design and interface design were introduced to implement the prototype of WGBMS. And Object-Relational Database Management System (ORDBMS) was used to construct the WGBMS database.

Peptide deformylase (PDF) is a metalloenzyme that removes the N-terminal formyl groups from newly synthesized proteins. It is essential for bacterial survival, and is therefore-considered as a potential target for antimicrobial chemotherapy. However, some bacteria including medically relevant pathogens possess two or more def-like genes. Here we have examined two PDFs from Bacillus cereus. The two share only 32% sequence identity and the crystal structures show overall similarity with PDF2 having a longer C-terminus. However, there are differences at the two active sites, and these differences appear to contribute to the activity difference seen between the two. BcPDF2 is found as a dimer in the crystal form with two additional actinonin bound at that interface.

Purpose: The purpose of this study was to understand the meaning of the driving force of life experienced by the elderly and the realistic structure of their experience. Methods: The research question was "What is the essential meaning of the driving force experienced by the elderly?". Data were collected from individual in-depth interviews between March, 2017 and May, 2017 and analyzed using Van Manen's hermeneutic phenomenological methodology to identify the essential themes of their experience. Results: Through the analysis process, 22 themes and 14 essential themes were derived. The 14 essential themes of the driving force of the life of elderly were as follows: 'Memories from the past', 'Poverty to escape', 'Hand down family's heritage', 'A body bound by marriage', 'A body necessary for old age', 'A dignified body even if they grow older', 'A body that does not want to fall', 'A fruit of my life', 'Mature real love', 'Unchanging fraternity', 'Extended family', 'An old friend with whom share my heart', 'Satisfied with the situation', and 'Expanding the breadth of life'. Conclusion: Nursing programs that assess the driving force of life supporting the elderly and supports the driving force of such a life should be developed.
