Port Logistics Services have been revolved by the physical role in trade between countries. Making a profits of Logistics Firms have been limited by distinct in the markets and a governments's control to save logistics costs. The conjunction of mobile telecommunication technology and logistics information system have showed a new possibility to logistics firms. This study's aim is to understand the impact of logistics information system based on smart phone's characters on the maritime companies performance. Various studies on logistics information have been doing. but it is rare to find studies in the mirror of a working level view. so The focus of this study is to grasp mediation role of Information system variables between customer attitude and companies performance through the empirical study on the practical logistics information system based on smart phone'characters. The results of analysis showed that not only customer attitude but also various variables of information system have a impact on better working conditions and customer supports. The logistics system's role in business has been growing constantly. therefore, We need a new angle for a role of logistics information system.

This study performs material nonlinear analysis of connection parts at noise barriers, which have a light weight. Subsequent numerical simulation results for three types of models (standard, double, and standard models strengthen by ribs) present that the applied connections for target noise barriers constructed show suitable structural performance. In this paper, the existing finite element elastic stress analysis using the ABAQUS program is further extended to study the plastic stress distribution of the noise barriers. The numerical results for various parameters are verified by comparing different steel types with stresses occurred in the noise barrier from the numerical simulation.

Purpose: The purpose of this study was to report on splenic artery aneurysms (SAAs) treated by transcatheter embolization in our single-center institution and to evaluate the clinical outcomes of patients with SAA by aneurysm location. Materials and Methods: The original medical records and imaging results of 52 patients with SAA treated in our center between January 1, 1995 and December 31, 2013 were reviewed. Of these cases, 7 patients (13.5%) underwent surgery, 4 patients (7.5%) underwent serial observation, and 1 patient had stent insertion only, leaving 40 patients (78.9%) who underwent endovascular treatment using a coil, with or without N-butyl-2-cyanoacrylate. Results: Aneurysms were located in the distal third of the splenic artery in 27 patients (67.5%), in the middle third in 9 cases (22.5%), and in the proximal third in 4 cases (10%). Of the 40 included patients, 25 were female (62.5%). Twentyeight patients (70%) were asymptomatic. The mean aneurysm diameter was 2.48 cm (range, 0.8–6.0 cm). Complications involved pancreatitis (n=1) and early spleen infarction (n=29: <1/3 in 14, 1/3–2/3 in 10, and >2/3 in 5). Postembolization syndrome was noted in 26 patients (65%). There were no significant differences by aneurysm location in the postoperative increase in the values of white blood cells, amylase, lipase, and C-reactive protein (P=0.067, P=0.881, P=0.891, and P=0.188, respectively). Conclusion: At our institution, endovascular management is safe, has high technical success, and represents the first-line treatment for SAA, regardless of aneurysm location
