Based on a complete understanding research in Information and Communication Technologies (ICT), the Intelligent Transport Systems rapidly build up innovative applications to ensure real time attainment as well remote management of driven information, provide a huge range of services and involve many actors in automotive ecosystem. In this paper, we present an intelligent cloud computing for handling data received from traffic sensing technologies. Transportations technologies applied in ITS have played a great role in collecting data from devices deployed in vehicles and highway infrastructures utilizing broadband wireless technologies to the Cloud. In order to facilitate the interested in automotive industry to use data collected and afford services to the car's owner, a scalable acquisition, access to computing resources and offered services are the primary goal of the proposed cloud computing.

Multimedia broadcast multicast services (MBMS) have evolved to accommodate broadcasting services in 3GPP standards. One long-standing approach is to comprise the multimedia broadcast multicast service single-frequency network based on the cellular networks of mobile operators, and another approach adds a broadcasting network to 3GPP standards. In this paper, we overview the MBMS architecture and key entities in MBMS services. In addition, the trends of MBMS are discussed in terms of technology and 3GPP standards, where MBMS functionality is described according to 3GPP releases. Finally, we discuss its capability through a comparison with ATSC 3.0, which is the latest terrestrial broadcasting standard, and then we present the current status and future perspectives of MBMS in 3GPP.

The identity verification is one of the most important technologies in online services. Many services in society are provided online, and the service is provided after confirming the user's identity. Users can do a lot of things online, but they also have side effects. Online digital information is easily manipulated and it is difficult to verify its authenticity, causing social confusion. Accordingly, there has been a movement for individuals to directly manage their identity information using DID. In this paper, we propose a system that can authenticate identity by directly adding own personal information and issuing an identifier using DID technology based on a private blockchain. Then, to verify the proposed system, the scenario is executed and verified.

It has been debating on the performance evaluation of professional construction management (PCM) services since its introduction to Taiwan's construction industry more than a decade ago. Several evaluation systems were proposed by previous researchers. However, there has no comparison study been conducted for the feasibility, effectiveness, and appropriateness of these systems to the performance management (PM) of practical PCM services. This paper is intended for this end to compare the existing PCM performance evaluation systems in Taiwan. A real world design/build (D/B) building project was selected for case study. The result of case study concludes and compares the pro's and con's of the three systems. At the end, it recommends strategies for selecting the most appropriate PCM performance evaluation for PCM services.

Nowadays Web Services are one of the most rapidly developed technologies and have become platform for e-ecommerce as well as B2B model. Therefore, when Web Services use SOAP as a protocol for communication, their security should be considered. However, those SOAP messages are prone to XML attacks that can create a foundation for typical faults and make it vulnerable to use. Unfortunately, recent researches established that solutions to deal with these problems have several limitations. In this paper, we explore attacks on SOAP messages and also provide confidentiality and integrity solutions. It is a tolerant scheme which is able to automatically detect and fix typical faults occurred in SOAP messages to combat with the security threats in order to improve its reliability.

Guide robots that provide services in public places have recently emerged as a non-face-to-face solution with the spread of COVID-19 and are growing. However, most guide robots provide only the same level of intelligence and the same interaction in different and changing environments. Therefore, its usefulness is limited and customers' interest is quickly lost. To solve this problem, it is necessary to develop social intelligence that can improve the robot's environment and situational awareness performance, and to continuously maintain customer interest by providing personalized and situational services. In this study, we developed guide robot services based on social HRI components that provides multi-modal context-aware. We evaluated service usefulness by measuring user satisfaction and frequency of use of the service through the survey. We analyzed the service quality attributes to identify the differentiating factors of guide robot based on social HRI components.

Firstly, this article expounds that business service industry plays an important role in adjusting industrial structure, transforming mode of economic growth, improving people's living standards, enhancing Enterprise's Kernel Competitiveness and promoting the development of service industry. Then it analyzes the development of business services in Shandong from two perspectives. The first perspective, by using methodology for statistical analysis, it will review the development scale, professional level, the number of opening units, quantity of employment, and operating revenue of business services in Shandong. On this basis, the article will summarize its development characteristics, experience and existing shortcomings. The second perspective, by using comparison analysis methodology, to compare the development of Shandong with Jiangsu, Guangdong, Zhejiang and Shanghai's and found the subjective and objective factors that restrict the development of business service industry in Shandong. In the light of restricting factors, countermeasures have been developed based on the experience at home and abroad. These countermeasures will contribute to promoting the optimization and upgrading of industrial structure, improving industrial competitiveness and speeding up the economic development rapidly and stably.

In June and July 2015 and 2017, typical signs and symptoms of brown rot were observed on the fruit of Japanese apricot, peach, apricot, Japanese plum, and sweet cherry with incidence levels of 2-5% in Jeonju and Imsil, Korea. Early symptoms were small, circular, light brown spots that eventually destroyed entire fruit. Small sporodochia later appeared on the surface. Conidia isolated from each host were one-celled, hyaline, lemon-shaped and borne in branched monilioid chains. The optimal temperature range for hyphal growth of all the isolates was $20-25^{\circ}C$. The growth of hyphae was faster on potato dextrose agar and oatmeal agar than others. Multiple alignments using the ITS sequences from different host showed that they matched each other (100%). The ITS sequences showed 100% identity to those of M. fructicola. Based on the morphological characteristics and phylogenetic analysis via internal transcribed spacer (ITS), all the isolate was identified as M. fructicola. Pathogenicity of representative isolates was proved by artificial inoculation, fulfilling Koch's postulates. This is the first confirmed report on brown rot caused by M. fructicola on stone fruit in Korea.
