  • Although the development of mobile devices are made us a free life, they were displayed the subject of this financial crime and attacking forces in the other side. Among finance-related crime is become a serious crime that are targeting smartphones by SMS phishing, phishing, pharming, voice phishing etc. In particular, SMS phishing is increased according to phenomenon using the nature of a text message in the mobile. SMS phishing is become new crime due to the burden to the smartphone user. Their crime is also the advanced way from the existing fraud, such as making the malicious apps. Especially it generates loopholes in the law by a method such as using a foreign server. For safe from SMS phishing attacks, proactive pre-diagnosis is even more important rather than post responses. It is necessary to deploy blocking programs for detecting SMS phishing attacks in advance to do this. In this paper we are investigating the process of block types and block apps that are currently deployed and presenting the evaluation of the application of the detection block setting app.

  • Purpose: In order to enhance safety, the Korea Navy is making efforts to introduce a safety and health management system and to develop a risk assessment system, while safety accidents keeps occurring. A development plan was proposed through an inspection of the Safety Management System(SMS). Method: To diagnose the Korea Navy's safety management system, changes in the safety environment, documentation system, and safety and health management system operation were reviewed, points to be improved were found, and improvement directions were derived. Result: There is a need for an SMS standard that can present the Korea Navy's safety policy and safety management direction, and a safety program that provides guidelines for implementing it in a standardized manner. To this end, we were able to confirm the feasibility of linking the requirements of the US Navy's SMS and the international standard ISO 45001 standard together with the Korea Navy's safety management system. Conclusion: The Korea Navy's safety management system needs to clearly present safety policies and standards, and have public confidence and effectiveness in safety work through a standard program that can implement them, and for this, the development of a Navy SMS is necessary.

  • The presence of responsive loads in the promising active distribution networks (ADNs) would definitely affect the power system problems such as distributed generations (DGs) studies. Hence, an optimal procedure is proposed herein which takes into account the simultaneous placement of DGs and smart meters (SMs) in ADNs. SMs are taken into consideration for the sake of successful implementing of demand response programs (DRPs) such as direct load control (DLC) with end-side consumers. Seeking to power loss minimization, the optimization procedure is tackled with genetic algorithm (GA) and tested thoroughly on 69-bus distribution test system. Different scenarios including variations in the number of DG units, adaptive power factor (APF) mode for DGs to support reactive power, and individual or simultaneous placing of DGs and SMs have been established and interrogated in depth. The obtained results certify the considerable effect of DRPs and APF mode in determining the optimal size and site of DGs to be connected in ADN resulting to the lowest value of power losses as well.

  • Background: Stomach cancer is one of the five most common cancers in Iran. This study examined the effectiveness of a mobile telephone short-message service (SMS) based-education intervention using Health Belief Model (HBM) variables in improving dietary behavior in terms of stomach cancer prevention among a sample of Iranian female college students. Materials and Methods: In this quasi-experimental study, 124 female college students in the dormitories of Yazd University, Yazd, Iran were randomly selected and assigned to either the intervention (n=62) or the control group (n=62). Information (data) regarding HBM variables and dietary behavior related to stomach cancer prevention was collected by a self-administrated questionnaire. Forty eight messages were designed and sent to the participants' phones in the intervention group during the 48-day intervention period. Two groups were followed-up one month after the intervention delivered via SMS. Results: There were significant differences in HBM variables (except for the perceived severity) and the preventive dietary behaviors for stomach cancer in the intervention group compared to the comparison group following the education intervention delivered via SMS. Conclusions: SMS-delivered nutrition education intervention can be a practical strategy to improve dietary behavior related to stomach cancer prevention.

  • Purpose: The purpose of this study was to investigate the effect of a short message service intervention on adherence to maximal barrier precautions (MBP) and catheter-related blood stream infections. Method: The data were collected from March to September, 2008, at an 826-bed university-affiliated hospital in Daejeon. The study participants were 24 physicians who were inserting central catheters and 133 patients (control group 78 and intervention group 55) with central catheter insertions. The researcher sent the message (adherence to MBP and optimal recommendations) to each internal medicine doctor using the short message service (SMS) for cellular phones. Messages were sent monthly for 3 months. Data were analyzed by chi-square test and t-test using SPSS 12.0 windows program. Result: Adherence to maximal barrier precautions was significantly increased from 44.9% to 69.1% (p=.006) after the SMS intervention. But changes in the rate of CRBSI (catheter related blood stream infection) between the intervention group (1.89) and the control group (4.45) were not significant (p=.323). Conclusions: The results indicate that the SMS intervention is effective in increasing the adherence to maximal barrier precautions and the SMS intervention can be recommended for utilization in infection control nursing practice.

  • The purpose of this study is to investigate the applicability of the two dimensional model in natural rivers. In this study, two dimensional unite element model, SMS, is used to simulate a complex flow along with the sediment movements in the natural river. The RMA-2 model embeded in SMS is used to simulate flow phenomena and SED-2D model is employed to simulate sediment transport. The model is applied to the confluence zone of the Gam River and mouth of Nakdong River. For model calibration, the result of the unsteady flow analysis is compared with the Typhoon 'Rusa' data. In addition, the runoff analysis was conducted for the determination of the project flood and the flood forecasting. The simulation results presented the characteristics of two dimensional flow with velocity vector and flow depth. The sediment transport characteristics are shown in terms of sediment concentration as well as bed elevation change. Accordingly, the SMS model in this study turned out to be very effective tool for the simulation of the hydrodynamic characteristics under the various flow conditions and corresponding sediment transports in natural rivers.

  • KIOST developed a deep-sea mining robot called "MineRo" to collect manganese nodules in 2007. MineRo operates on flat ground. SMS (seafloor massive sulfide) deposits are shaped like undulating mountains. This paper deals with a numerical analysis model of a mining robot for SMS deposits. The mining robot consists of a tracked vehicle, chassis structure with a turntable, boom arm with 2 articulations, excavation tool, discharging unit, hydro-electric system, and sensing-and-monitoring system. In order to compare and analyze the dynamic responses of the driving mechanism, various tracked vehicles are modeled using commercial software. Straight driving simulations are conducted under undulating ground conditions. A conceptual design of a mining robot with four track systems for SMS deposits is modeled on the basis of these results.

  • Interaction of lateral loading, combined with axial force needs to be determined with care in reinforced concrete (RC) one-dimensional structural members (1D SMs) such as beam-columns (BCs) and columns. RC 1D SMs under heavy axial loading are known to fail by brittle mode and small lateral displacements. In this paper, a macro element-based algorithm is proposed to analyze the RC 1D SMs under monotonic or cyclic combined loading. The 1D SMs are discretized into macro-elements (MEs) located between the critical sections and the inflection points. The critical sections are discretized into fixed rectangular finite elements (FRFE). The nonlinear behavior of confined and unconfined concretes and steel elements are considered in the proposed algorithm. The proposed algorithm has been validated by the results of experimental tests carried out on full-scale RC structural members. The evolution of ultimate strain at extreme compression fiber of a rectangular RC section for different orientations of lateral loading shows that the ultimate strain decreases with increasing the axial force. In the examined cases, this ultimate strain ranges from 0.0024 to 0.0038. Therefore, the 0.003 value given by ACI-318 code for ultimate strain, is not conservative and valid for the combined load cases with significant values of axial force (i.e. for the axial forces heavier than 70% of the ultimate axial force).
