Development and Evaluation of Omni channel service based on Internet of Things for Hospitals
Omni-channel services based on the Internet of Things (IoT) technologies have emerged in various business environments. To enhance hospitalâs service quality and maximize benefits as well as provide seamless customer experience, this study applies IoT technology based on NFC, iBeacon(inclusing wearable devices) as an omnichannel service for integration of online and offline channel in hospital. First, we develop services based on IoT technology for omni channel of the hospital. Then, we will evaluate omni channel services from a CRM and BPI point of view through interview. To develop the IoT technology based on NFC, iBeacon, we conducted action research. The five phases in action research framework research include diagnosing, action planning, action taking, evaluation, and specifying learning phases. In this study, we focus on action planning, action taking, evaluation. At the action planning phases, eleven service models based on IoT technology for omni channel for hospital were designed. Service models were applied to the hospital by installing tags and beacons at the third phase. At the fourth phases, service models issues and knowledge on the whole application process were derived and summarized with respect to CRM (Customer Relationship Management) and BPI (Business Process Innovation) of hospital
Development of a piezoelectric multi-axis stage based on stick-and-clamping actuation technology
This paper presents the design, analysis and fabrication of a piezoelectric multi-axis stage based on a new stick-and-clamping actuation technology for miniaturized machine tool systems, referred to as meso-scale machine tool (mMT) systems. In the stick-and-clamping actuation system, shearing/expanding piezoelectric actuators, an inertial mass and an advanced preload system are configured innovatively to generate the motion of an inertial mass. There are two operating modes in the stick-and-clamping actuation technology: (1)Â stick mode and (2)Â clamp mode. In stick mode, the âslowâ deformation of the shearing piezoelectric actuators drives an inertial mass, which is located on the tips of the shearing piezoelectric actuators, by means of the friction force at their contact interface. On the other hand, in clamp mode, the expanding piezoelectric actuators provide the clamping force to an inertial mass when the rapid backward deformation of the shearing piezoelectric actuators occurs. The stick-and-clamping actuation technology also enables two-degrees-of-freedom (DOF) motion of an inertial mass in a single plane by perpendicularly stacking two shearing piezoelectric actuators. The 2-DOF piezoelectric multi-axis stage is developed on the basis of the stick-and-clamping actuation technology, and the dynamic and static performance analyses are conducted. The LuGre friction model for the contact interfaces is introduced, and their dynamic behaviours are characterized. In the open-loop static performance test, linear, diagonal and circular motions of the developed piezoelectric multi-axis stage are generated, and their performances are evaluated. The dynamic characteristics and static performances of the developed 2-DOF piezoelectric multi-axis stage show its applicability and effectiveness for the precision positioning system.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/58149/2/sms7_6_040.pd
Case Study on the Enterprise Microblog Usage: Focusing on Knowledge Learning
Knowledge Management Strategy can be classified by codification strategy and personalization strategy (Hansen et. al., 1999), and how to manage the two strategies were always studied. Also, current studies regarding the knowledge management strategy were targeted mostly for major companies, resulting in lack of studies in how it can be applied on SMEs. This research, with the knowledge management strategy suited for SMEs, sets an Enterprise Microblog (EMB), and with the EMB applied on SMEsâ Knowledge Management Strategy, it is reviewed on the perspective of SMEsâ Codification and Personalization Strategies. Through the advanced research regarding Knowledge Management Strategy and EMB, the hypothesis is set that âDepending on the development of the company, the main application of EMB alters from Codification Strategy to Personalization Strategy.â To check the hypothesis, SME that have used the EMB called âYammerâ was analyzed from the data of their foundation until today. The case study has implemented longitudinal analysis which divides the period when the EMBs were used into three stages and analyzes the contents. As the result of the study, this suggests a substantial implication regarding the application of Knowledge Management Strategy and its Knowledge Management System that is suitable for SME
Coderivations of Ranked Bigroupoids
The notion of (co)derivations of ranked bigroupoids is discussed by Alshehri et al. (in press), and their generalized version is studied by Jun et al. (under review press). In particular, Jun et al. (under review press) studied coderivations of ranked bigroupoids. In this paper, the generalization of coderivations of ranked bigroupoids is discussed. The notion of generalized coderivations in ranked bigroupoids is introduced, and new generalized coderivations of ranked bigroupoids are obtained by combining a generalized self-coderivation with a rankomorphism. From the notion of (X,â,&)-derivation, the existence of a rankomorphism of ranked bigroupoids is established

The aim of this article is to obtain more general forms than the papers of (Jun et al. (2010); Jun et al. (in press)). The notions of
-subalgebras of types , and are introduced, and the concepts of -support and -support are also introduced. Several related properties are investigated. Characterizations of -subalgebra of type are discussed, and conditions for an -subalgebra of type to be an -subalgebra of type are considered
Soft p-ideals of soft BCI-algebras
AbstractMolodtsov [D. Molodtsov, Soft set theoryâFirst results, Comput. Math. Appl. 37 (1999) 19â31] introduced the concept of soft set as a new mathematical tool for dealing with uncertainties that is free from the difficulties that have troubled the usual theoretical approaches. Jun [Y. B. Jun, Soft BCK/BCI-algebras, Comput. Math. Appl. 56 (2008) 1408â1413] applied first the notion of soft sets by Molodtsov to the theory of BCK/BCI-algebras. In this paper we introduce the notion of soft p-ideals and p-idealistic soft BCI-algebras, and then investigate their basic properties. Using soft sets, we give characterizations of (fuzzy) p-ideals in BCI-algebras. We provide relations between fuzzy p-ideals and p-idealistic soft BCI-algebras
Graphs Based on BCK/BCI-Algebras
The associated graphs of BCK/BCI-algebras will be studied. To do so, the
notions of (l-prime) quasi-ideals and zero divisors are first introduced and
related properties are investigated. The concept of associative graph of a
BCK/BCI-algebra is introduced, and several examples are displayed
