가정폭력 피해 이주여성 지원 제도 및 서비스에 대한 고찰: 문제점과 개선 방안을 중심으로

While public awareness on domestic violence has increased over the past few decades in Korea, little is known about domestic violence issues pertaining to immigrant women. This study is an attempt to provide an overview of domestic violence issues, legal and policy structures, and current social service system in place for battered immigrant women in Korea. The findings show that various sound legal and policy framework has been established over the past years, resulting in provisions added to the existing laws on domestic violence, policies developed specifying support for battered immigrant women and implementation of social service agencies to assist and protect the battered immigrant women and their families. Using the AAAQ framework by UN, we examined the current service delivery system. The result shows that service availability, accessibility, and acceptability are found to be quite compromised by gaps between the policy and practice. A large number of service providers are located in metropolitan areas, reducing the accessibility of battered women in other regions. A limited budget is also a barrier to provide comprehensive services to all in need. Lastly, a lack of translator and interpreter services limits accessibility and acceptability as both the service providers and the victims are unable to communicate with language barriers. Based on the findings, we suggested implications for policy and practice.

Patient’s Satisfaction and Barrier to Seek Services From the Nurses in a Tertiary Level Hospital

This Quantitative study was conducted among the patients of BIRDEM, Dhaka. The study's goal was to determine user expectations, client satisfaction levels, and the quality of health care supplied in a tertiary level hospital in Bangladesh. A total of 100 respondents were chosen by systematic random sampling and interviewed. The study's findings suggest that client happiness is influenced by providers' behavior, particularly respect and politeness. A reduction in waiting time (on average to 30 min) was more important to clients than a prolongation of the quite short consultation time (on average 2 min, 22 sec), with 75% of clients being satisfied. patients spend 10 minutes or less than that for checkup. Delays in service may be acceptable due to the high volume of patients, existing facilities, and the large number of service providers. Overpopulation at the healthcare facility was named as the cause by 29.8% of respondents, while lack of trained manpower and doctors were named as the causes by 22.5 percent and 19.7 percent, respectively. Finally, the study suggests that boosting resources, as well as effective supervision and monitoring, could help enhance the hospital's service quality.

Blockchain-based Multi-Purpose Authentication Method for Anonymity and Privacy

Various applications using smart contract, a leading application technology of blockchain, are being rapidly introduced to the industrial sector. As a result, services in various fields are actively being developed. Currently, most of the services are offered on a variety of platforms, not blockchain-based. If these services are linked to prepaid features that provide anonymity in smart contracts, a more diverse service scenario could be created. In this paper, we propose scenarios that provide certification for various purposes based on smart contracts. It provides a scenario that provides the privacy of the contract signed by the customer while retaining the anonymity provided by blockchain. Smart contracts register keys that do not give a clue to guess the encoding keys and deliver hash functions of the child keys that change each time with authentication parameters.In addition, the master seed that can generate these authentication parameters is designed to be kept only by the user and the service provider to be able to verify them. It is proposed by considering both a single service provider transaction and a smart contract authentication model that is shared with a large number of service providers. To generate these child keys, we proposed a mechanism to use the method of generation of child keys based on the Elastic Curve Cryptography public-key method. Various attack scenarios were analyzed to complement the scenario and the efficiency of the proposed mechanism was analyzed. In addition, differences and excellence were compared by organizing scenarios that had the same purpose as scenarios in the relevant study

Priority based clustering the service providers in federated cloud

Cloud is a trending technology now a days. In this technology world now everyone are moving with the cloud. A cloud federation technique is one of the best ways to select any services from the service providers by the user at any time. As large number of service providers in the federation, user need to be select best service provider and the selection of service provider get delayed in the federation. We proposed the cluster based approach to select the best service provider for user request and reducing the selection time of service provider. In previous papers there is no Automated Selection for the selection of best service provider. Our proposed work is based on Automated Selection model i.e., we applied k-means algorithm for grouping the similar services and categorizing the service providers into three groups. Such as Cluster-1, Cluster -2 and Cluster -3, after cluster these cluster sorted in order based on the final centroid of each cluster. Now user request to be compared with the middle cluster centroid and directed to respective cluster for service selection. If more than one service provider offers similar services in the cluster then priority decision tree to be invoked for tie break. This technique works better than existing algorithms and time also to be saved in selection of service.

Privacy preserving system for integrated broadcast-broadband services using attribute-based encryption

A number of integrated broadcast-broadband services have recently been launched which allow the viewers to receive the content via the airwaves together with additional information about the content via the Internet. By providing personal preferences viewers can expect more attractive and personalized services. Viewers would be only willing to share their information with providers that they trust. On the other hand, the viewers would like to distribute their preferences as wide as possible so that they can enjoy more interesting and diverse services. In this paper, a privacy preserving system for integrated broadcast-broadband service is proposed. The system allows viewers to share their personal information with service providers that satisfy certain criteria (possess certain attributes). An implementation of the system using a previously proposed attribute-based encryption scheme is given and the computation cost of the system is examined in practice. Using the system, a viewer can safely receive personalized services from a large number of service providers.

Cocriação de valor no transporte rodoviário de carga fracionada: um estudo de caso

Este artigo investiga se a cocriação de valor pode ser aplicada pelos prestadores de serviços de transporte. O estudo focalizou os transportadores e operadores logísticos. Um estudo de caso múltiplo foi realizado. Constructos afetos ao tema cocriação de valor foram extraídos da literatura para a consolidação da fundamentação teórica da pesquisa. Os seguintes tópicos foram investigados: demandas de valor dos compradores, critérios utilizados pelos compradores para avaliar o valor oferecido pelos prestadores de serviços e a possibilidade de cocriação de valor entre os compradores e vendedores. Os achados apontam duas principais barreiras para a cocriação de valor nos serviços de transporte, a saber: um grande número de prestadores de serviços (o que força os provedores de serviço a focalizar essencialmente a dimensão custo dos serviços) e as exigências dos clientes. A combinação dos referidos elementos sugere a impossibilidade de adoção de cocriação no contexto estudado. Esses resultados também podem indicar a existência de um limite inferior para a abordagem de valor no setor de serviços (por caso, nos serviços de transporte de carga).

Imperialist competitive algorithm with PROCLUS classifier for service time optimization in cloud computing service composition

Aiming to provide satisfying and value-added cloud composite services, suppliers put great effort into providing a large number of service providers. This goal, achieved by providing the “best” solutions, will not be guaranteed unless an efficient composite service composer is employed to choose an optimal set of required unique services (with respect to user-defined values for quality of service parameters) from the large number of provided services in the pool. Facing a wide service pool, user constraints, and a large number of required unique services in each request, the composer must solve an NP-hard problem. In this paper, CSSICA is proposed to make advances toward the lowest possible service time of composite service; in this approach, the PROCLUS classifier is used to divide cloud service providers into three categories based on total service time and assign a probability to each provider. An improved imperialist competitive algorithm is then employed to select more suitable service providers for the required unique services. Using a large real dataset, experimental and statistical studies are conducted to demonstrate that the use of clustering improved the results compared to other investigated approaches; thus, CSSICA should be considered by the composer as an efficient and scalable approach.

Automatic Network Service Discovery and Selection in Virtualization-Based Future Internet

The next generation Internet is expected to support a wide range of network applications with highly diverse requirements. Network virtualization, which will play a key role in the future Internet, allows a large number of service providers to offer various network services upon shared network infrastructure. Therefore, discovery and selection of the most appropriate network service for meeting the requirement of each application becomes an important issue in the virtualization-based future Internet. The Service-Oriented Architecture (SOA) offers an effective architectural principle for heterogeneous system integration that may facilitate realizing the notion of network virtualization. The research reported in this paper explores application of the SOA in network virtualization to address the network service discovery and selection problem. A broker system is proposed based on the SOA for automatic network service discovery and selection, a scalable and efficient protocol is developed for updating network service information, and the multi-attribute decision making technique is employed for ranking and selecting network services to meet application requirements. Performance evaluation results are also presented in the paper to show the effectiveness of the proposed system and developed protocol and algorithm.

Flexible service selection with user-specific QoS support in service-oriented architecture

Along with the development of the service-oriented architecture (SOA) and cloud computing, a large number of service providers have created an intense competitive world of business. Consequently, it is becoming increasingly complex to select a service provider for a user as a result of their various economic and social attributes. In this paper, we state the problem of how to find the appropriate services with satisfying the users' multiple QoS requirements. We consider the service's response time, trust degree and monetary cost. And inspired from the mode of Web search engine, such as Yahoo, Google, we propose an innovative service selection algorithm for SOA systems. The algorithm can recommend a number of suitable services based on the user's QoS requirements.Compared with the existing scheduling algorithms, our solution is much more flexible in supporting the multiple objectives and user personalization. We study the scalability of the algorithm with different numbers of jobs, service providers and QoS criteria. And we find that it can capture user's preferences value in less than six times of job submissions.
