Due to the rapid growth of social networking community (SNC), research into SNC user's behavior has recently emerged as an important issue in information systems. An individual makes a decision whether or not to continually use his or her own SNC and to purchase digital items to decorate it. Most previous research has focused on a user's continuance intention and has ignored the importance of purchase intention. This study develops and empirically tests an integrated model designed to predict a user's two types of behavioral intention：continuance intention and purchase intention based on the expectation-confirmation model (ECM) and a dual model of relationship maintenance mechanism.The results indicate that perceived usefulness, satisfaction, personalization, and switching cost have important influences on the formation of SNC continuance intention. The results also show that perceived usefulness and satisfaction does not have any significant impacts on purchase intention, while personalization, learning, attractiveness of alternatives, and continuance intention significantly affect it.

RFID system the key technology of ubiquitous era, has been emphasized in logistics. Logistic enterprises are required to apply RFID systems considering their investment costs, actual effectiveness, operational satisfaction and so on. For such a purpose, many applicable methods of RFID system have been developed A method that RFID tags are directly attached to products or pallets is utilized in most cases. However, this method requires expensive investment cost, frequent replacement of damaged tags for the small and medium (SM) third party logistics. In this paper, we analyze statistically the current status and requirements of SM third party logistics. Based on their requirements, we propose the realtime warehousing-delivery management by the method to attach a RFID tag to each warehouse rack, together with the economy analysis index in order to evaluate economical efficiency. Consequently, this method is expected to reduce Investment cost and to improve operational effectiveness and satisfaction.

Since aged water treatment facilities could threaten the sustainable water supply, asset management system has been adopted for their systematic management. Level of Service(LoS) is one of critical components of asset management and could be quantified through benchmark index(BMI). Water supplier could estimate consumer's satisfaction and their performance through BMI to improve the LoS. We developed BMI for water treatment facilities from customer's satisfaction survey. BMI, represented with the Total Service Score(TSS), was assessed with water quality, water pressure, taste and odor, water rate, and service quality with weighing factors. BMI could, further, be used to assist the analysis of the life cycle cost to increase the unit of LoS.

Hanok has been widely distributed as a support policy by local governments for the purpose of improving residential environment. In this study, Hanok in a rural area was founded was to evaluate the user's satisfaction. Hanok between residents and the perception of architects and tries to figure out the difference. Current Hanok residents showed higher satisfaction, but they showed negative response for high construct cost, plane form of building, insulation performance and noise. According to the comparison of recognition between residents and architectural designers, they showed differences in "Low soundproofing", "lack of storage space", "Equipment", "Tile", "The modularity of the flat panel design", and "The modularity of construction materials" and it was examined that architectural designers group had higher preference for traditional materials and forms. For succeeding to the traditional architectural factors of Hanok and distributing it as modern house, the research on use of modern materials and modulation of plane and members should be performed for reducing construction cost and improving insulation performance.

Purpose: This study was conducted in order to present basic policy data for introduction of a home-based physical therapy (HBPT) policy. Methods: The study surveyed physical therapists and patients for six weeks, in order to identify satisfaction with physical therapy. The statistical significance of the management plan with regard to costs and cost estimation and payment methods was determined and managed according to the operating principals of HBPT, eligibility criteria, number of visits, treatment time, and team approach. Results: Through the survey all groups of patients and physical therapists recognized the need for HBPT. They felt that the most desirable methods for activation of physical therapy visits involve precise diagnosis and evaluation through a team approach. While making regular visits to the patient three times a week, an expert visiting physical therapist with 3 to 5 years of experience in the clinical field could provide central nerve developmental treatment in less than 60 minutes; this service could be provided at a reasonable cost, minimizing unnecessary hospital visits, reducing time, medical expenses and facilitating a quick recovery due to psychological satisfaction resulting from a decrease in the psychological anxiety patients often experience in medical institutions. Conclusion: Based on the study results provided above, if HBPT is to be introduced, appropriate pricing and programs should be based on the results of pilot projects.

Consumers are not simply consuming products anymore. They now take part in developing new products. Thus, it is essential that we devise a variety of consumer-oriented marketing strategies to keep close relationships with consumers. The purposes of this study were as follows: 1) to explore the relationship between customer participation and surveys on its effect, 2) to compare groups with respect to customer participation, and 3) to see whether there is a cause-effect relationship between the customer participation and surveys on its effect. Frequency analysis, correlative analysis and discriminate analysis were used to analyze the data. The results of testing hypotheses can be summarized as follows. we find that, as for customer participation factors, there is significant relationships among survey factors including customer satisfaction, cost reduction, customers' prior occupations. The current analysis exhibits favorable results in the customer participation and such factors. The analysis shows that there is significant difference between the active groups and the passive groups in all the new product development related factors; customer satisfaction, cost reduction, customers' prior occupations. Finally, this perhaps indicates that the result of the survey depends on whether firms are positive or negative in introducing customer participation.

In order to satisfy customers, it is important to identify the quality elements that affect customers' satisfaction. The Kano model has been widely used in identifying multi-dimensional quality attributes in this purpose. However, the model suffers from various shortcomings and limitations, especially those related to survey practices such as the data amount, reply attitude and cost. In this research, a model based on the text sentiment analysis is proposed, which aims to substitute the survey-based data gathering process of Kano models with sentiment analysis. In this model, from the set of opinion text, quality elements for the research are extracted using the morpheme analysis. The opinions' polarity attributes are evaluated using text sentiment analysis, and those polarity text items are transformed into equivalent Kano survey questions. Replies for the transformed survey questions are generated based on the total score of the original data. Then, the question-reply set is analyzed using both the original Kano evaluation method and the satisfaction index method. The proposed research model has been tested using a large amount of data of public IT service project evaluations. The result shows that it can replace the existing practice and it promises advantages in terms of quality and cost of data gathering. The authors hope that the proposed model of this research may serve as a new quality analysis model for a wide range of areas.

This study aims to analyze the effect of absorptive capacity on technology collaboration performance and the moderating effect of innovation intermediaries. We set absorptive capacity (potential, realized) as independent variables and technology collaboration performance (relative technology level, development period, cost savings, new product development, collaboration satisfaction) as dependent variables, with innovation intermediaries as a moderating variable. We conducted a survey of 145 ICT companies that experienced technology collaboration and analyzed the data using 101 valid responses. The results show that potential absorptive capacity has a significant effect on new product development and collaboration satisfaction, while realized absorptive capacity has a significant effect on relative technology level, cost savings, and new product development. Furthermore, innovation intermediaries have a moderating effect between realized absorptive capacity and new product development. The contribution of this study to academia and industry is that it highlights absorptive capacity as a key factor influencing technology collaboration performance. The limitations of this study include the lack of accurate measurement of absorptive capacity and innovation intermediaries, as well as a lack of control over external factors. These limitations should be addressed through more in-depth research by systematically defining and measuring them in future follow-up studies.

Background: The high cost of intrathecal morphine pump (ITMP) implantation may be the main obstacle to its use. Since July 2014, the Korean national health insurance (NHI) program began paying 50% of the ITMP implantation cost in select refractory chronic pain patients. The aims of this study were to investigate the financial break-even point and patients' satisfaction in patients with ITMP treatment after the initiation of the NHI reimbursement. Methods: We collected data retrospectively or via direct phone calls to patients who underwent ITMP implantation at a single university-based tertiary hospital between July 2014 and May 2016. Pain severity, changes in the morphine equivalent daily dosage (MEDD), any adverse events, and patients' satisfaction were determined. We calculated the financial break-even point of ITMP implantation via investigating the patient's actual medical costs and insurance information. Results: During the studied period, 23 patients received ITMP implantation, and 20 patients were included in our study. Scores on an 11-point numeric rating scale (NRS) for pain were significantly reduced compared to the baseline value (P < 0.001). The MEDD before ITMP implantation was 0.59 [IQR: 0.55-0.82]. The total MEDD increased steadily to 0.77 [IQR: 0.53-1.08] at 1 year, which was 126% of the baseline (P < 0.001). More than a half (60%) responded that the ITMP therapy was somewhat satisfying. The financial break-even point was 28 months for ITMP treatment after the NHI reimbursement policy. Conclusions: ITMP provided effective chronic pain management with improved satisfaction and reasonable financial break-even point of 28 months with 50% financial coverage by NHI program.
