Public institutions and governments develop discussions on the premise that they can facilitate smooth public communication with the socially vulnerable by promoting citizens' welfare by providing voice-based service chatbots to citizens. The purpose of the study is to propose a plan for intelligent governments to provide quick and efficient administrative services by efficiently managing knowledge and information within and outside government organizations based on ICT and facilitating access and use of information for citizens, especially vulnerable groups. This paper confirms that citizens' attitudes, perceptions, and expectations for public institutions ahead of voice-based service provision are positive through small surveys and interviews with experts with knowledge of artificial intelligence, discuss the technical aspects of voice-based services, the significance and necessity of public institutions. In addition, the government and public institutions are considering the implications of using and providing voice-based services. As a result, chatbot's voice-based service is of great significance in providing an opportunity and platform for wider citizens to participate in intelligent government, to strengthen information accessibility, guarantee and strengthen human rights and basic rights of the socially vulnerable.

In the rapid digital transformation era, kiosks have become a common element in daily life. However, their widespread deployment has introduced new challenges for socially marginalized groups, including individuals with disabilities and the elderly. This study aims to evaluate the usability of kiosks for individuals with low vision and propose improvement strategies. The study was conducted with eight low-vision university students from A University in Gyeongsangbuk-do and four non-disabled university students from Daegu. Usability was assessed through experiments involving a self-service certificate issuance kiosk and a fast-food restaurant kiosk, using Jakob Nielsen's five usability evaluation criteria: learnability, efficiency, memorability, error prevention, and satisfaction. The results revealed that individuals with low vision faced significant difficulties with small text size, low contrast, no physical buttons, and lack of screen zoom functionality. To address these issues, the study recommends enhancements such as increasing text size and contrast, incorporating physical buttons, adding zoom functionality, ensuring consistent UI design, and providing auditory feedback. This study provides foundational data for enhancing information accessibility for individuals with low vision. It offers critical insights into kiosk design and policy recommendations, thereby contributing to the mitigation of the digital divide.

This study aims to explore the utilization of kiosks, a case of self-service technology in library services, by applying task-technology fit theory to reveal the factors that affect the satisfaction and continued use of library kiosk services and to conduct a review of library non-face-to-face services. We organized the kiosk characteristic factors through a literature review and established a research model mediated by related theories. We collected 229 valid questionnaire data from users with experience using library kiosks and analyzed them using SPSS 26.0 and SmartPLS 4.0 programs. The analysis results confirmed that the fit of library services and self-service technology was significantly influenced by the usefulness and enjoyment of kiosk technology characteristics and the kiosk-friendly environment of the usage environment attributes. In addition, we found the fit between library services and self-service technology to significantly affect library kiosk usage satisfaction and intention to continue using the kiosk, so this study proposed a plan for library kiosk services utilizing the significant factors. In addition, to effectively use the kiosks as a non-face-to-face library service, we suggest operating them in line to provide library information materials, install them in various locations within the library to increase accessibility, and provide education on how to use them for learning and to raise positive awareness of the kiosks for the digitally disadvantaged.

It's hard to express a lot of information within the drawings and the specifications as construction projects have gradually become large-size and complex. So, disputes are caused by that and reason that the usual practice(culture) of contract of the constructions in Korea is based on unfair rather than the fair principle between clients and contractors. However, the contractors don't try to solve this kind of things because they are worried about at their disadvantage situation. Therefore, this paper deduced the factors in the pre-dispute phase by analysing the cases of the civic counseling in the office of supply and the pre-dispute factors, and conduct analysis on the factors' importance by using AHP. The results will be used for a check-list to prevent the disputes.

This paper presents the torque control algorithm of a permanent magnet synchronous motor(PMSM) for an electric scooter. The volume of the in-wheel type motor is restricted due to the complicated mechanical structure in wheel of an electric scooter, so the hall sensors instead of resolver and encoder for the rotor position sensors are installed. In this paper, the rotor speed and position are estimated from the speed estimator for vector control of a PMSM with hall sensors. The motor starts to rotate at standstill in BLDC mode with 120 degree conduction. After start up, the operating mode is changed to the vector control with maximum torque per ampere(MTPA) operation at low speeds and flux weakening control at high speeds. The performance of the proposed control algorithm is verified through the experiment in the electric scooter.

Construction Projects have many participants by characteristic, scale and contract. Those also have complicated communication structure. So, claim and dispute occur continuously for conflicting communication. In many claim and dispute cases, it usually occurs between builder and owner. Unfair practices by owners position cause main claim and dispute. This study analyses judgment type, cause and compensation ratio in korean commercial arbitration case and provides the dispute information for builder that has weak position by contract. It draws analysis information for managing and controlling dispute that order type, judgement type, cause and failure case. Using these analysis information, it hopes to help inducement of dispute agreement and save time and economic damage for builder during construction. It also hopes to rise construction completeness by providing dispute management information.

Regardless of East and West, public libraries provide various services to their communities based on collections. The decisive reason for local residents to visit public libraries is to access and borro w collections. An important condition maintenance to support these activities and services is the library circulation(usage) rules. Therefore, this study compared and analyzed the library membership, maximum loan items, loan period, loan reserve and renewal, overdue fines, disposal of lost and damaged items, loan of non-book materials, loan regulations for the disabled. And after checking the relative deviations in connection with the library cases of major developed countries, this study proposed the improvement of circulation rules. In order to minimize public complaints about circulation services and to relieve the burden of practitioners such as personnel disadvantage due to administrative audit for non-recoverable ite ms, public libraries must faithfully rearrange the circulation rules and regulations.

Korean society became an 'aging society' in 2000 years with a population of 65 years and over occupying $7.2\%$ of the whole population. And we expect that a population of 65 years and over will occupy $14.4\%$ in 2019 years, so Korean society will enter into an 'aged society' Older adults can't react correctly and rapidly to the disaster due to the decline of the physical function, therefore victims of older adults due to the disaster will increase as much as aging proceeds. For reducing sacrifices of older adults due to the disaster, 1 suggest that the propulsion of the disaster service policy for disaster week people like older adults, the policy of minimizing casualties due to fires, reinforcement of fire resources and enlargement of disaster services in rural communities, offering information about disaster services and reinforcement of functions of public relations, making new connection systems (e.g. educating welfare and post officials as volunteer fire officials), supplement of fire fighters, and the policy of lightening fire equipments.

Population data are usually provided at administrative spatial units in Korea, so areal interpolation is needed for fine-grained analysis. This study aims to compare various methods of areal interpolation for population subgroups rather than the total population. We estimated the number of elderly people and single-person households for small areal units from Dong data by the different interpolation methods using 2010 census data of Seoul, and compared the estimates to actual values. As a result, the performance of areal interpolation methods varied between the total population and subgroup populations as well as between different population subgroups. It turned out that the method using GWR (geographically weighted regression) and building type data outperformed other methods for the total population and households. However, the OLS regression method using building type data performed better for the elderly population, and the OLS regression method based on land use data was the most effective for single-person households. Based on these results, spatial distribution of the single elderly was represented at small areal units, and we believe that this approach can contribute to effective implementation of urban policies.

In this article, I will provide a philosophical discourse on digital sexual violence that is a technological version of male violence. First, critical analysis of the mechanism of the spatiality and the temporality of the hidden and illicit camera is developed to focus on the immeasurable damage of this violence. I elaborate a notional division between digital sexual violence and cyber sexual violence. Secondly, the ease of taking images of women's bodies and the rapid transmission of these images through the advancement of digital communication technology and hyperconnectivity, lead to use these images as a new digital monet for men. They consolidate their male solidarity by reaffirming female inferiority and humiliating women. Thirdly, the invention of the structure of the new affect to resist to digital sexual violence is crucial. For that, it would be necessary to pass from the sexual shame to the sexual displeasure and to the socio-political indignation. These would create another opportunity to resist to digital sexual violence.
