The results showed that 1) for legal issues and obstacles to the implementation, it was found that the network partners do not literally participate and most of the police operation is carried out on the orders of the commanding officers.&nbsp; Another critical issue is the budget while the relevant laws and regulations are sufficient. However, most of those involved do not recognize the laws and regulations on the operation. In addition, police officers do not adhere to the guidelines of the Royal Thai Police Regulations on Promoting Public, Local Communities, and Organizations to Participate in Police Affairs B.E. 2551. Regarding relevant legislation, laws on public participation in foreign police operations are consistent with Thailand's operation to promote public participation in police affairs, such as Japan's community police, and provide opportunities to establish plans or measures in maintaining public order and safety within the area to be following the needs of each locality or community. As for the Security Business Act of B.E 2558 in Thailand, it is consistent with the law on foreign private security that focuses on the potential of security personnel and the importance of licensing to perform duties including the role of being a part to play a role in supporting the operation of the police officers. This is for the development of related laws and regulations, consisting of 2 approaches, namely 1) the development of measures or mechanisms to solve problems and 2) innovative measures or mechanisms.</p> Meechai Sicharoen, Tanansak Borwornnuntakul, Sophon Srivapot, Sahaphat Homjan, Kraiwoot Wattanasin, Itthipol Sookying Copyright (c) 2024 International Journal of Science and Innovative Technology https://creativecommons.org/licenses/by-nc-nd/4.0 https://ph01.tci-thaijo.org/index.php/IJSIT/article/view/253869 Fri, 12 Jan 2024 00:00:00 +0700 Innovative System for Urban Aging Health Development https://ph01.tci-thaijo.org/index.php/IJSIT/article/view/253870 <p>&nbsp; &nbsp; &nbsp; &nbsp;This study on "<strong>The Innovation driving health policies and urban development for the Older Persons in the Bangkok community area</strong>" has the purpose of analyzing factors affecting the practice of health policies and urban development for older persons in the community of Bangkok by analyzing documents and in-depth field data collection by the staff from the BMA Social Development Office through the framework of decentralization and model of the policy implementation process. This study reveals that under the transfer of the mission to the agency (BMA Social Development Office), policy resources in terms of 1) budget 2) personnel 3) premises, and 4) materials and durable articles, are sufficient to support the implementation of the project to achieve the policy objectives. And the policy resources and policy objectives are relevant to communication between organizations since communication is a mechanism for ordering and receiving commands to recognize the operational guidelines by using the resources of the agency for operating following policy purposes. However, the authorization and duties of the BMA Social Development Office focusing on promoting and organizing social welfare, providing welfare in the form of shelters, and emergency homes, have demonstrated the potential to operate under the transfer of missions related to social welfare and assistance to older persons, making the operations to follow the policies received, while the integration of work within the agency and the attitude of the operators who are aware of the operational guidelines result in a mechanism that drives the practice or action to allocate housing welfare for older persons in the Bangkok areas to be achieved. However, despite problems and obstacles in terms of economic, social, and political conditions, the project can still be carried out which requires policy resources in terms of integrating agencies to support the implementation to be achieved according to the objectives of the policy.</p> Supajira Durongdej Copyright (c) 2024 International Journal of Science and Innovative Technology https://creativecommons.org/licenses/by-nc-nd/4.0 https://ph01.tci-thaijo.org/index.php/IJSIT/article/view/253870 Fri, 12 Jan 2024 00:00:00 +0700 Innovation on Optimizing and Propelling the Development of Police Comprehensive Investigative Skills https://ph01.tci-thaijo.org/index.php/IJSIT/article/view/254581 <p>The efficacy of the police's investigative performance in delivering justice to the public is questionable. This study aimed to construct and disseminate an investigative skill model to police officers in the Nakhonpathom province region. The target population for this research consisted of ninety individuals: faculty members affiliated with the Faculty of Police Science, ten members of the investigation group Police Cadet Academy, and eighty third- and fourth-year police cadets. The findings were as follows: 1) The investigative skills model, which emphasized collaboration and integration among police investigators, forensic officers, and external agencies, was applicable and suitable for implementation in all cases. The evident advantages encompassed collaboration in their tasks and the acquisition of an identical set of case data; the implementation of CRIMES technology and its searching system facilitated the acquisition of information more quickly and easily; facilitated swift coordination or information transmission; and enabled efficient management of time and</p> <p>travel expenses. Regarding the provision of public services, the model reduced the victim's repetition of case-specific details, which could have resulted in inaccurate or insufficient information or negatively impacted their emotional and mental well-being. The system additionally furnished up-to-date case statuses, notwithstanding the absence of the responsible officer. It was determined that the dissemination of the model improved public satisfaction and the officers' capacity to manage cases effectively. Nevertheless, personnel and the number of cases received might limit the application to all cases. An authentication criterion for editing and access was suggested.</p> Kannika Kukudrua, Jirut Sonkratai, Puthon Pukasab, Neti Srisakul , Chatchanun Leeratermpong Copyright (c) 2024 International Journal of Science and Innovative Technology https://creativecommons.org/licenses/by-nc-nd/4.0 https://ph01.tci-thaijo.org/index.php/IJSIT/article/view/254581 Fri, 12 Jan 2024 00:00:00 +0700 Tour Guide Application for Tourist via Line Chatbot - In the case of Multicultural Tourism, Narathiwat Province - https://ph01.tci-thaijo.org/index.php/IJSIT/article/view/255134 <p>The objectives of this research composed of 1) to develop a tour guide application and provide information via Line Chatbot of multicultural tourism for southern border cities. 2) To evaluate the efficiency of the application in practical use via Line Chatbot in the specific location at Narathiwat Province 3) To evaluate the satisfaction and effectiveness of the application by providing updated and corrected various information and all times auto responses between the application and user for better convenience and practical use.
