The vocational guidance and advising education enrollment are one of the most important tasks in the enrollment process and promote the quality and reputation of the University. Admissions counseling offices at Universities and Colleges play a major role in vocational guidance and advising education enrollment. However, the support of these units is limited by office hours, speed and advisory efficiency, and besides, handling and answering questions process may also encounter obstacles such as: overload, misinformation, problem with the transmission, language barriers, expressions, limited time, support resources,… Thus we decided to do research to understand this situation. Then creating a dataset supports vocational guidance and advising education enrollment activities. We also design and integrate chatbot into the school system to support the admissions counseling process.

With the advent of Web2.0 era, more and more consumers begin to use social media to obtain the required information, this kind of information search mode of human interaction -- social information search and traditional human-computer interactive search mode has the essential difference. Understanding the motivation to consumer social information search is of great significance to understand the characteristics of consumer information search. Through the literature review, this study summarizes the three motivations to consumer social information search: risk aversion motivation, entertainment motivation and social motivation. In future studies, we will use structured interviews and empirical methods to further confirm the motivations of consumers' social information search. This study is of certain significance to enrich the theory of social information search and to formulate targeted marketing strategies for enterprises.

Background/Objectives: This study is a basic stage of research to expand support for cervical cancer vaccines. Methods/Statistical analysis: Data was collected and refined and analyzed using R and Excel, which are statistical tools for big data analysis. A survey was conducted on college students in their 20s and tried to analyze it. Findings: In addition, as a result of conducting a correlation analysis with the factors affecting cervical cancer through R, it was found that they were related to each other. Improvements/Applications: The results of this study suggested the need for cervical cancer vaccine support from the government and suggested ways to expand it.

The study examined the relationship between the Academic Hardiness and Motivational Beliefs, Goals and Values of tertiary students towards mathematics learning. The respondents of the study consist of about 167 BS Mathematics third year students of the Bulacan State University during Academic Year 2016-2017. The descriptive – correlational method of research was employed in the study. To gather the necessary data, the researcher adopted two instruments - the Academic Hardiness Scale developed by Benishek and Lopez (2001) and the Learning Motivation Questionnaire, a section from the Motivated Strategies for Learning Questionnaire (MSLQ) developed by Duncan and McKeachie (2005). Pearson correlation analysis and Test of significance were used to interpret the results. The study showed that among the three related attitudes of Academic Hardiness (Commitment, Control and Challenge), the students posted the highest mean in the Commitment domain. Seemingly, the difficulty posed by mathematics has not negated students’ interest and involvement in doing their mathematical tasks. Regarding the status of the students’ Motivational Beliefs, Goals and Values toward mathematics learning, results yielded a high overall mean rating reflective of the high ratings received in almost all the motivational constructs: Intrinsic Goal Orientation, Extrinsic Goal Orientation, Task Value, Controls of Learning Beliefs, Self-Efficacy for Learning and Performance except Test anxiety. The highest perceived mean is on Task Value which demonstrates the respondents expressed interest in mathematics and their acknowledge importance of the subject in their preparation to life-long learning. For Test Anxiety, perceived mean rating is average. This result simply reiterates the psychological distress experienced by students when taking examinations in mathematics. Lastly, analysis also showed that students’ Academic Hardiness and the identified motivational constructs has significant positive correlation with each other.

Triton is the world’s most serious malware and it’s now spreading by all over the networks. The hackers has deployed malicious code or malware which let them take over the plant’s safety instrumented systems. These physical controllers and their associated software codes are the last line of defense against life-threatening crisis. Many factories now perform automated processes using computers. However, in 2017 an attack aimed at this emerged. We have detected that a malicious program is installed in the emergency safety device. All of the automation equipment used in these industrial sites is called ICS, and Triton is one of the malicious codes targeting these ICSs. After the hacker sets up the target, the attacker uses a secure shell (SSH) based tunnel to deliver the attack tool and execute remote commands of the program after accessing the IT and OT networks, installing back doors in the computer network, and then accessing the target safety instrumentation system (SIS) controller in the OT network while scouting the network, moving the internal network, and maintaining access. Therefore, we proposed ICS malware for countermeasure to prevent from Triton attack.

Hospital service quality is the variation between the patient’s perceptions about the services delivered by a healthcare organization and their expectations about healthcare organizations delivering such services. Patient perspective is the ultimate indicator of healthcare service quality as it enables them to judge the performance of the services provided by the hospital. A huge gap exists between the quality of the healthcare services provided by the hospitals in rural and urban areas. The quantitative study was conducted to understand the perceptional differences in the service quality between the urban and rural hospitals. It was a survey that documented the patient perspective of hospital service quality by measuring various dimensions like healthcare delivery, facilities, financial access to care, diagnostic aspects of care, health personnel conduct and drug availability. The sample consisted of 115 residents, chosen based on convenience, from urban and rural areas. The responses were analyzed using SPSS 20 software. From the findings, it was inferred that there are perceptional differences in the service quality between rural and urban hospitals. Further, perceptional differences exist in the facilities provided between the rural and urban hospitals. Financial and physical access to care widely differ between rural and urban hospitals. Overall, the perception of service quality is higher in the urban hospitals than in the rural hospitals. Thus, study provides insights to the hospital administrators and the managers in enhancing the quality of services, based on the perceptions and needs of the patients.

This paper proposes the basic analytical framework of web development systems from the perspective of system dynamics. Based on the feedback characteristic of web development activities, we analyze the causality in the web development from six aspects including work stress, web development, motivation, developer maintenance, recruitment and outsourcing and create a casual loop diagram of web development. Through system analysis, crucial factors needed for web developers to accomplish web development tasks continuously and stably are illuminated. The results show that external variables such as new recruitment and case outsourcing can have a short-term effect on the system, while internal variables such as work motivation and work stress have a greater influence on web development activities, which will result in a fluctuation of job performance. From the perspective of management, countermeasures are put forward on how to mobilize the enthusiasm and initiative of developers and improve productivity.
