The main purpose of this study was to examine the influence of cultural values on social media eWOM in the hospitality industry in China, Korea, and the USA. The result of this study indicates Chinese and American people engage more than Korean people when they try to purchase hospitality product and service This study particularly provided a cross-cultural study of comparison among these countries and t he findings of this study are expected to provide important practical assistance for global marketing strategies in social media.
A Population‐based Assessment of the Continuity of Ambulatory Care

A strategy is described in which explicit patient care criteria are used to measure the continuity of the health problem solving process. Prevalent diseases arc selected to represent the work load of the health system. Continuity is defined in terms of rates of transition between the major clinical elements: screening, the definitive diagnostic evaluation, treatment, and follow-up evaluation. Results define critical dropout patterns and promote constructive assessment of the health care system. Sample data from the Indian Health Service are presented and discussed.
Incendiary Characteristics of Endotracheal Tubes with the Carbon Dioxide Laser

The ignition characteristics of the American Hospital, Portex®, polyvinyl chloride, and red rubber tracheal tubes commonly available have been evaluated using a standard carbon dioxide laser. The added hazard of the increased combustibility of the impregnated line on endotracheal tubes and the hazard of commonly utilized anesthetic or lubricating materials are discussed. The safety limits which, experimentally, indicate levels of energy and laser burst time which seem to preclude the hazard of ignition are outlined. The potential danger of postburn bronchiolitis is noted, along with appropriate treatment.
Efficacy and tolerability of quetiapine in patients with schizophrenia switched from other antipsychotics

OBJECTIVE The Seroquel Patient Evaluation on Changing Treatment Relative to Usual Medication (SPECTRUM) study assessed the efficacy and tolerability of quetiapine (Seroquel™) in patients with schizophrenia switched from treatments providing suboptimal outcomes. METHODS This was an international, open-label, non-comparative study, designed with titration to 400 mg/day quetiapine over 7 days, then flexible dosing (300-750 mg/day) for 11 weeks. Efficacy was assessed with the Positive and Negative Syndrome Scale (PANSS); Clinical Global Impression (CGI) Severity of Illness and Global Improvement scores; and the Calgary Depression Scale for Schizophrenia (CDSS). Clinical benefit and tolerability were also assessed. RESULTS The mean modal dose of quetiapine was 505 mg/day; 509 patients switched to quetiapine from olanzapine (13%), risperidone (11%), conventional antipsychotics (37%) and combinations of antipsychotics (28%), amongst others. Significant decreases in CGI Severity of Illness and PANSS scores and a significant improvement in CDSS score resulted from the switch (all P<0.001 versus baseline). There were significant reductions in extrapyramidal symptoms (EPS) on the Simpson-Angus Scale (SAS) and Barnes Akathisia Scale (BAS) (both P<0.001 versus baseline) and a low incidence of EPS-related adverse events (4.7%). CONCLUSION Results indicate that switching to quetiapine was clinically beneficial for patients with poor efficacy or intolerable side effects on their previous antipsychotic medication.
A case study on business model innovations using Blockchain: focusing on financial institutions

Purpose Blockchain is a distributed ledger, in which the blocks containing transaction details are connected chronologically to form a series of chains, thus raising the possibility of improving the process and innovating business model for the financial institutions. The purpose of this paper is to study the actual cases of Blockchain applied in Korea in 2017, so that a vision of business model innovation of financial institutions can be drawn. Design/methodology/approach The financial institutions in Korea are in the technology verification stage to introduce Blockchain technology. Since there is an insufficient amount of actual measurement data, case study method was adopted. The authors interviewed ICT officers of major banks in Korea. The purpose of the interview was to understand the relationship between Blockchain and business models of financial institutions, and the effects and challenges that Blockchain has on the business model of financial institutions. Findings From the perspective of financial institutions, the emergence of Blockchain does not just have technical significance – emergence of highly efficient database system – but has the possibility that if the business model of existing financial intermediaries disappears or get reduced, the financial services relying on them can disappear altogether, or some of them can be replaced, and financial transaction patterns of consumers can be changed. As a case studies researched for this paper, it was discovered that the distributed characteristic of Blockchain cannot be applied when actually developing financial services.
An adaptive hybrid rekeying protocol for dynamic multicast groups

In secure multi-party communications, the Logical Key Hierarchy scheme has been proved to be communication optimal for large groups. However, this scheme still suffers from an expensive rekeying cost when the group is very dynamic. To reduce the rekeying cost, Zhu et al. suggested to partition the logical key tree in two sub-trees based on the duration of each member in the multicast group. Although this scheme reduces the rekeying cost for long-duration members, the key server still needs to send a potentially large number of rekeying messages for the set where member actions are very frequent. Based on the idea of separating long and short-duration members, we propose a hybrid rekeying protocol aiming at reducing the rekeying cost of the set of dynamic members. Thanks to this new protocol, the key server can adapt its rekeying scheme regarding to the frequency of membership operations. For each rekeying interval, the key server will first compute and compare the rekeying cost of three different schemes which differ regarding to the data structure defined for the dynamic set and will choose the scheme with the cheapest cost. Thus, the rekeying cost will always be optimized for each rekeying interval.
Wireless Energy and Data Transmission ASIC for Blood Pressure Measurement in an Aneurysm Implant

Aneurysm implant requires multiple pressure sensors integrated into the stent graft for recording pressure profile inside an aneurysm sac. This paper details the design of an ASIC which receives power wirelessly using inductive coupling, fetches pressure data from a seperate chip and transmits data wirelessly. Besides, the ASIC extends the functionality of the external pressure measurement chip to support up to four pressure sensors by using an analog multiplexer. Error detection and forward error correction are implemented to improve data integrity for wireless data transmission. The design has been implemented and tested in 350 nm CMOS technology.

Financial stability oh islamic banks: a systemic risk perspective

The late global financial crisis reveled the fragility of the conventional banking system under an adverse systemic event, but highlighted Islamic banks resilience in comparison with their conventional counterparts. The aim of this thesis is to empirically assess the claim regarding Islamic banks strength to support the financial system stability, based on measuring their systemic risk contribution to the overall financial system. The work is applied is applied first to the MENA region from 2007 to 2014, and is applied next to the GCC region from 2005 to 2014. We use stock market returns of publicly traded banks, which we classify into fully-fledged Islamic banks (IB), conventional banks (CB), and conventional banks with Islamic services window (CBwin), from which we construct stock market banking indices (banking sectors), and measure the systemic risk taking into consideration the interconnectedness of the banking sectors within the financial system. We measure the systemic risk of the banking sectors using correlation network models, augmented by equity based market measures of MES, SRISK, ∆CoVaR, and CES, and we extend those measures by developing netted systemic risk ones that employ partial correlation instead of the marginal one, to take the multivariate nature of systemic risk into account. We test our novel NetMES measure using the Bayesian averaging analysis. The results confirm the lower contribution of Islamic banks to systemic risk, and thus their strength to support the financial stability, under the limitation of the crisis materialization within the real economic side, upon which the IB banking sector stability and strength deteriorates.

Robust Reversible Watermarking for relational database

The large structure of dataset for sharing for particular target or authenticate target but there are some other parties that can attack on data easily and use that data illegally and can claim that data ownership. Attacker can gain ownership on that sharing data. Due to this original data get modified and quality of data also reduced so this original data is not useful for any extraction information system, it gives irrelevant data or reduced data which is not useful for further processing. To avoid this we used a system Reversible Watermarking which protects data from attack of middle parties while sharing data and also preserve ownership of the data. It avoids data tampering and reduction of data. Quality of data also gets preserved. Feature selection in RRW uses all combinations of features to calculate importance (MI) of the features. Also RRW does not support non-numeric data. We introduced technique which works on nominal data and uses less features for calculation which enhance the speed and accuracy and performance of RRW. In supervised learning, feature's importance depends on co-relation between Feature and class variable, there is no need to consider all combination.
Bio-Inspired Technique: An Adaptive Routing for Reliability and Energy Efficiency Method in Wireless Sensor Networks

Οver recent years, enοrmοus amοunts οf research in wireless sensοr netwοrks (WSNs) have been cοnducted, due tο its multifariοus applicatiοns such as in envirοnmental mοnitοring, οbject tracking, disaster management, manufacturing, mοnitοring and cοntrοl. Sοme WSN applicatiοns require the energy-eﬀicient and link reliability as impοrtant perfοrmance parameters. Hence, this paper presents a rοuting prοtοcοl that cοnsiders these twο criteria. We prοpοse a new mechanism called Reliable and Energy Eﬀicient Rοuting (REER) tο reduce the packets drοp during data cοmmunicatiοns. It is an adaptive methοd tο ensure high rοuting reliability in if failures οccur due tο the mοvement οf the sensοr nοdes οr when sensοr nοde’s energy depletiοn. This is accοmplished by intrοducing a new methοd tο create alternative paths tοgether with the rοuting infοrmatiοn οbtained during the route detection stage. The gοal οf this οperatiοn is tο update and οﬀer new rοuting infοrmatiοn in οrder tο determine multiple pοssible paths tο increase reliability οf the sensοr netwοrk. Simulatiοn results demοnstrate that the prοpοsed methοd shοws better results in terms οf packet delivery ratiο and energy eﬀiciency.
The Role of Oxygen‐carrying Capacity in Myocardial Ischemia

Myocardial ischemia results when myocardial oxygen demand exceeds oxygen supply. The oxygen content of blood is only one of several interdependent variables influencing myocardial oxygen supply. The impetus for assessing the contribution of the oxygen content of blood to myocardial ischemia, and thus the need to treat anemia, stems from current concern about the risks associated with blood transfusion and the recognition that hemodilution has protean effects on the oxygen-carrying capacity of blood. The rheological changes that accompany hemodilution favorably influence the delivery of oxygen to the tissues and have the capacity to at least partially compensate for the decrease in blood oxygen content during hemodilution. However, nonrheological compensatory mechanisms (e.g., cardiac effects) also influence oxygen delivery and may profoundly influence the adequacy of tissue oxygenation. Furthermore, occlusive vascular lesions that restrict blood flow to the tissues also profoundly influence tissue oxygenation. The evidence in the myocardium and in systemic tissues indicates that considerable degrees of normovolemic hemodilution are well tolerated in physiological settings. In contrast, coexisting disease such as coronary artery stenosis may limit the patient population that benefits from normovolemic hemodilution. Unfortunately, well-controlled prospective studies of normovolemic hemodilution in patients with severe vascular or cardiac disease have not yet been conducted. As we progress to that point, it will be especially important to critically examine studies that use anesthetized or revascularized preparations. Results obtained under controlled conditions of hemodilution may not apply to postoperative anemia in awake patients with coronary artery disease who are experiencing the stress of surgery.

Depression Is a Mediator for the Relationship between Physical Symptom and Psychological Well-being in Obese People

This present study aimed to investigate the association effect of obesity status, physical symptom, insecure attachment, and depression on psychological well-being in non-diabetic healthy Koreans. Height, weight, waist circumference, blood pressure, and socio-psychological questionnaires (insecure attachment, depression, and physical symptom psychological well-being, etc.) were examined in 123 healthy Koreans. Student t-test, correlation analysis, and mediation analysis were performed. Study subjects were divided into 2 groups based on body mass index (BMI, kg/m2): obesity (BMI ≥ 25, n = 36) and non-obesity (BMI < 25, n = 87). Obese people were older and showed higher proportion of males than non-obese ones. Regarding the values of socio-psychological test, obesity group showed lower insecure attachment, and higher physical symptom than non-obesity group. In correlation and mediation analyses, depression was positively related to insecure attachment and physical symptom in both BMI groups. Positive relationship between physical symptom and insecure attachment was observed only in non-obesity group, but not in obesity group. The effect of insecure attachment on psychological well-being was completely mediated by depression in both BMI groups. On the other hand, the effect of physical symptom on psychological well-being was completely mediated by depression in obesity group, but not in non-obesity group. In conclusion, this study presented that the effects of physical symptom and insecure attachment on psychological well-being were completely mediated by depression in obese healthy Koreans, but not in non-obese ones. It will provide useful data for extending the knowledge on the relationship between the physical health and mental health.
Intuitive interaction with semantics using augmented reality: a case study of workforce management in an industrial setting

Semantic technologies are a powerful tool able to give meaning to flat data by creating ontologies that link information systems that live separately, but which complement each other in order to provide a common understanding of a domain. However, these technologies are also often seen as difficult to profit from due to their limited availability to non-experts. Tools to manipulate and to interact with information contained in ontologies are restricted to the very tools experts use to create such ontologies, or in the best case to traditional user interfaces built for specific applications relying on ontologies. In this paper, we present an innovative way to access, manipulate, and interact with semantic information by combining this powerful data basis with the benefits of Augmented Reality technologies. We look at an industrial setting with role-based and intuitive access to a semantic source of contextualized information regarding workforce, asset and inventory management as well as assigned tasks. In this approach industrial managers and service technicians are supported during their decision making processes and execution of assigned tasks.
Modeling of temperature variations in MOSFET mismatch for circuit simulations

Temperature effect is one of the critical factors in manufacturing variability which could affect the designed circuit. This paper presents a MOSFET mismatch model with the consideration of temperature variations using physical based SPICE model parameters. The model development includes the mismatch measurement at different temperatures and enhancement of standard device model card. Mismatch temperature coefficients with respect to threshold voltage and carrier mobility are used to improve the prediction of mismatch model. The comparison between measured and Monte Carlo simulated data is presented for the verification purpose. The model is applied into the circuit design example to show the significant of the extracted mismatch temperature coefficients.
Is Social Management a Profession? Managerial Styles Within Italian Welfare Organizations

ABSTRACT In Italy, the rescaling of local welfare systems is leading to profound changes in the management of welfare organizations. Local public administrations play a key-role in planning social services, favoring the strengthening of a managerial jurisdiction. Adopting the perspective of organizational professionalism, we interviewed 20 social managers, to understand how their jurisdiction is developing in the balance between ‘bureaucratic’ constraints and ‘professional’ aims. The findings were compared with the competencies defined by the Network for Social Works Managers (NSWM). We argue that the way in which social managers take their responsibilities affects the effective protection of the social rights, locally.
Competitiveness of Greek virgin olive oil in the main destination markets

Purpose The aim of this study is to analyze the competitiveness of the Greek virgin olive oil in the main destination markets (German, Italian, U.K. and U.S. market). Design/methodology/approach In order to achieve the aim, in the first stage the Revealed Comparative Advantage Index (RCA2) was employed showing that Greek virgin olive oil has a comparative advantage over the other suppliers (mainly Italy and Spain) in the markets under examination. In the second stage, the estimations of an import demand system for each market were estimated. Findings Results demonstrate clearly the competitive advantage of Greek virgin olive oil in the German market but not so clear in the rest of the markets. A strategic shift to export high quality branded virgin olive oil instead of bulk, it seems necessity, in order the Greek virgin olive oil to dominate to the international markets. Originality/value Though there are similar works, specialy for Spanish olive oil, there is no analogous research work for the Greek oliv.
Factors Associated with Postmenopausal Osteoporosis: A Case-Control Study of Belgrade Women

The aim of this study was to investigate factors related to osteoporosis in postmenopausal women in Belgrade. A case-control study was conducted during 2006–2007. The study group consisted of 100 newly diagnosed osteoporosis patients and 100 age-matched controls (±2 years). The inclusion criteria for the case group were newly diagnosed osteoporosis confirmed by dual-energy X-ray absorptiometry of the lumbar spine and being menopausal (at least 2 years of amenorrhea). The inclusion criteria for the control group were postmenopausal women with confirmed normal bone mineral density of the lumbar spine by dual-energy X-ray absorptiometry. All study participants were interviewed using a structured questionnaire. Univariate and multivariate logistic regression analyses were used. The following factors were significantly independently related to osteoporosis: low body weight (P < 0.001), thin constitution in childhood (P = 0.002), history of previous fracture (P = 0.033), menopause at age <47 years (P < 0.001), family history of fracture (P = 0.005), and less frequent consumption of cheese (P = 0.027) and fish (P = 0.020). The majority of factors identified may be modifiable and could be influenced to prevent postmenopausal osteoporosis.
