Web services (WS) present a new promising software technology, which provides application-to-application interaction. They are built on the top of existing web protocol and based on open XML standards. Web services are described using WSDL, and the UDDI is a integration directory provide registry of Web Services descriptions. WSDL provides information of Web Services but it is getting more and more important to know more than those provided by WSDL. From WSDL we can not get the information like usage of WS, performance of WS, complexity of WS, usability of WS with other web service. In this paper, we proposed a new method for Web Services so called Public Web Services Analyzer (PWSA). This technique is based on analyzing various public UDDI registries in order to get various kinds of statistics of web services. Those statistics will be used by both web services developers and consumers for finding them suitable services for their needs. PWSA guarantees that it can provide enough information to find right web services for both Web Services Consumers and Web Service Developers.

The purpose of this study is to find out the right strategies for social welfare education and the efficient human resource management of public social workers. Not to make any flaws when looking for the appropriate strategies, this report studies how outcomes of social welfare education influences the performances of public social workers and how the empowerment is connected to the relationship between the social welfare education and the performances of public social workers. For clearer study, a survey was conducted for 396 public social workers and the Structural Equation Model by AMOS was used to analyze the outcome. According to the result, the Fitness Index of the Casual Model, proposed by this study, was similarly matched with that of theological model. The Casual Model proved that it explains the connection between social welfare education, job performance and empowerment. Hence, to improve performance of public social workers, various education and training policies for human resources management are needed and basically associates related social welfare education should do their effort. Also to enhance empowerment of public social workers, various measures are needed.

In the Digital Convergence era, the center of social networking is moving into on-line space. This means also that space for public is moving into the on-line space. Along with this, spaces in commercial area, offered as attraction factors, are taking a role as a public space. So, this paper defines these spaces mentioned above as public space and the like. Liberal and affluent communication of Digital Convergence has caused in new spatial cognitions such like, constant social space, flowing space, temporary space, and multiple space. This means the hybridization of on-line and off-line space and the advent of public convergent space. However, it is on-line-centered convergence and has positive effects and negative effects on relationship. This paper suggests the optimization of public convergent space to solve the problems and make better a public space for relationship. For achieving this, social disclosure is grasped as the common way to start relationship both off-line and on-line, and it is proved that social disclosure has three characters such as self-presentation, corporeality, and subjectivity. Subsequently, the differences of the roles of off-line and on-line space are separated by each individual character. These are self-presentation of performance vs. storytelling, corporeality of embodiment vs. disembodiment, and self-subjectivity vs. inter-subjectivity. By recognizing that there are multilevel spectrums between the formers and the latters, this paper presents the direction of the spatial configuration of public convergent space which offers the right of manipulation of self-disclosure. It will be used for presenting the prototype of public convergent space.

Cloud computing provides a broad range of services like operating systems, hardware, software and resources. Availability of these services encourages data owners to outsource their intensive computations and massive data to the cloud. However, considering the untrusted nature of cloud server, it is essential to encrypt the data before outsourcing it to the cloud. Unfortunately, this leads to a challenge when it comes to providing search functionality for encrypted data located in the cloud. To address this challenge, this paper presents a public key encryption with equality test for heterogeneous systems (PKE-ET-HS). The PKE-ET-HS scheme simulates certificateless public encryption with equality test (CLE-ET) with the identity-based encryption with equality test (IBE-ET). This scheme provides the authorized cloud server the right to actuate the equivalence of two messages having their encryptions performed under heterogeneous systems. Basing on the random oracle model, we construct the security of our proposed scheme under the bilinear Diffie-Hellman (BDH) assumption. Eventually, we evaluate the size of storage, computation complexities, and properties with other related works and illustrations indicate good performance from our scheme.

The Korean government's strategy to combat coronavirus disease 2019 (COVID-19) has focused on non-pharmaceutical interventions, such as social distancing and wearing masks, along with testing, tracing, and treatment; overall, its performance has been relatively good compared to that of many other countries heavily affected by COVID-19. However, little attention has been paid to health equity in measures to control the COVID-19 pandemic. The study aimed to examine the unequal impacts of COVID-19 across socioeconomic groups and to suggest potential solutions to tackle these inequalities. The pathways linking social determinants and health could be entry points to tackle the unequal consequences of this public health emergency. It is crucial for infectious disease policy to consider social determinants of health including poor housing, precarious working conditions, disrupted healthcare services, and suspension of social services. Moreover, the high levels of uncertainty and complexity inherent in this public health emergency, as well as the health and socioeconomic inequalities caused by the pandemic, underscore the need for good governance other than top-down measures by the government. We emphasize that a people-centered perspective is a key approach during the pandemic era. Mutual trust between the state and civil society, strong accountability of the government, and civic participation are essential components of cooperative disaster governance.

The purpose of this study was to determine differences of balance performance to upright standing, forward bending posture, and sudden load during forward bending posture in subjects with and without a history of low back pain. A study was conducted on 8 subjects with low back pain and 13 healthy subjects. Dynamic Balance System was used to measure the postural sway index, left-right sway index, and anterior-posterior sway index on balance performance. There were no differences between subject groups on balance performance during upright standing. Balance performance was increased in forward bending posture and decreased in sudden load during forward bending posture in subjects with low back pain. These results suggest that subjects with low back pain demonstrated increased activity and decreased reaction times of trunk muscles.

Ocular region recently emerged as a new biometric trait for overcoming the limitations of iris recognition performance at the situation that cannot expect high user cooperation, because the acquisition of an ocular image does not require high user cooperation and close capture unlike an iris image. This study proposes a new method for ocular image recognition based on BRISK (binary robust invariant scalable keypoints). It uses the distance ratio of the two nearest neighbors to improve the accuracy of the detection of corresponding keypoint pairs, and it also uses geometric constraint for eliminating incorrect keypoint pairs. Experiments for evaluating the validity the proposed method were performed on MMU public database. The person recognition rate on left and right ocular image datasets showed 91.1% and 90.6% respectively. The performance represents about 5% higher accuracy than the SIFT-based method which has been widely used in a biometric field.

Today, in the information society, since the government administration of all countries places importance on clarity and efficiency, the authority concentration of the administration is inevitable. Therefore, the Parliament, which is a legislative body, is at a time when the policy control function to check and monitor it is becoming more important. In particular, due to the emergence of parliamentary democracy, in the reality that the people must elect representatives and represent their own opinions, the parliamentary inspection system is very valuable in that it satisfies the right of the people to know and ultimately enables the people to democratically control the administration. The role of the Parliament moves from the inherent legislative function to the information collection and disclosure of government administration, discussion and resolution of political issues, and observation and supervision of the administration. And it can be seen as the global trend. As a result of this trend, status and role of the National Assembly is being strengthened from the legislative body to the control agency of government administration. Thus, the most substantive authority of Article 61 of the Constitution can be deemed the parliamentary inspection system. The parliamentary inspection system is a system that let exercise the legislation, budget, and authority to control of state administration by identify the challenges and policy implementation of each country's institutions through the audit of the executive administration's overall government administration performance outside the National Assembly. However, due to the amendment of Constitution in 1988, the parliamentary inspection right and investigation of state administration right had reinstated and the parliamentary inspection system, which is being implemented annually, is the 31st year of the year in 2019. However, the general evaluation of the public is negative and insufficient time for inspections, lack of sanctions on nonattendance witnesses, excessive data submission, and refusal to submit materials by the administration were pointed out as the problem. Therefore, in this paper, the researcher tries to point out the overall problems of the parliamentary inspection system and to summarize the effective improvement plans.

This study explored the sustainability of a blockchain-based cultural art performance video platform through the construction of Gyeonggi Art On, a new media art broadcasting station in Gyeonggi-do. In addition, the technical limitations of video content transaction using block chain, legal and institutional issues, and the protection of personal information and intellectual property rights were reviewed. As for the research method, participatory observation methods such as in-depth interviews with developers and operators and participation in meetings were conducted. The researcher participated in and observed the entire development process, including designing and developing blockchain nodes, smart contracts, APIs, UI/UX, and testing interworking between blockchain and content distribution services. Research Question 1: The results of the study on 'Which technology model is suitable for a blockchain-based performance video content distribution public platform?' are as follows. 1) The blockchain type suitable for the public platform for distribution of art performance video contents based on the blockchain is the private type that can be intervened only when the blockchain manager directly invites it. 2) In public platforms such as Gyeonggi ArtOn, among the copyright management model, which is an art based on NFT issuance, and the BC token and cloud-based content distribution model, the model that provides content to external demand organizations through API and uses K-token for fee settlement is suitable. 3) For public platform initial services such as Gyeonggi ArtOn, a closed blockchain that provides services only to users who have been granted the right to use content is suitable. Research question 2: What legal and institutional problems should be reviewed when operating a blockchain-based performance video distribution public platform? The results of the study are as follows. 1) Blockchain-based smart contracts have a party eligibility problem due to the nature of blockchain technology in which the identities of transaction parties may not be revealed. 2) When a security incident occurs in the block chain, it is difficult to recover the loss because it is unclear how to compensate or remedy the user's loss. 3) The concept of default cannot be applied to smart contracts, and even if the obligations under the smart contract have already been fulfilled, the possibility of incomplete performance must be reviewed.
