Delivering the weapons system requirements of the military to the acquirer is an essential activity for the development of the defense industry as well as the successful acquisition of a weapons system. In order to ensure successful delivery of requirements, the creation of a weapons system Operational Requirements Document(ORD) has been mandated since 7. 2013. However, according to the results of a study which analyzes recently-created ORD, a number of problems are occurring. For one, some items in created ORDs differ from what the ORD template requires. In addition, the overall mission area of the weapons system to be acquired and the core parts(operation performance, system performance, and core performance) of ORD are being poorly recorded. In response, this study presented a framework(focused on a creating method of overall contents and core parts) for the creation of ORDs which can solve the problems that arose during ORD creation in the past.

This paper is mainly associated with setting out an agenda for the transformation of security by creating a new framework for a security system, which can maximise its effectiveness. Noticeably, this research shows empirically that crimes are getting a major cost to organisations, which if reduced by security and investigations could reap substantial rewards to the finances of an organisation. However, the problem is that the delivery of security is frequently delegated to personnel (e.g. security guards) with limited training, inadequate education, and no real commitment to professionalism - 'sub-prime' security, finally causing security failures. Therefore, if security can be enhanced to reduce the crime cost, this will produce financial benefits to business, and consequently could produce a competitive advantage. For this, the paper basically draws upon Luke's theoretical framework for deconstructing 'power' into three dimensions. Using this three-dimensional approach, the paper further sets out a model of how security can be enhanced, utilising a new Security Risk Management (SRM) model, and how can this SRM model create competitive advantage in business. Finally, this paper ends with the six strategies needed to enhance the quality of security: refiguring as SRM, Professional Staff, Accurate Measurement, Prevention, Cultural Change, and Metrics.

Many customers are no longer satisfied with mass-produced goods. They are demanding customization and rapid delivery of innovative products. Many companies are now realizing that the best way to reduce life cycle costs is to evolve a more effective product development paradigm using Internet and web based technologies. Yet there remains a gap between current market demands and product development paradigms. The existing CAD systems require that product developers possess all the design analysis tools in-house making it impractical to employ all the needed and newest tools. Hence, this paper addresses how assembly operation analysis can be embedded transparently and remotely into a service-oriented collaborative assembly design environment. A new assembly operation analysis framework is introduced and a relevant architecture and tools are developed to realize the framework. Instead of the current sequential process for verifying and validating an assembly design, a new Virtual Assembly Analysis (VAA) method is introduced in the paper to predict the various effects of joining during actual collaborative design. As a case study, arc welding and riveting processes are investigated. New service-oriented VAA architecture and its VAA components are proposed and implemented on prototype mechanical assemblies.

With the outbreak of coronavirus disease 2019 (COVID-19) pandemic, health policymakers are adopting new policies regarding the issue of immunization disparities, especially for children in low-income communities of color who lack awareness and thereby access to vaccines. The purpose of this paper is to propose an evaluation framework using program theory-based evaluation approach and logic model to analyze and evaluate the immunization disparities in children aged 19-35 months. Data is collected from New York City department of Health and the U.S. Census Bureau for Northern Manhattan Start Right Coalition program which consists of 19,800 children, and the community-provider partnership includes 26 practices and 20 groups. Program theory is used to evaluate this community-based initiative with the logic model which is a visual depiction that illustrations the program theory to all stakeholders. The logic model highlights the resources, activities, outputs, outcomes, and impacts of the program to guide to planners and evaluators and to call attention to the inadequacies or flaws in the operational, implementation and service delivery process of the program in offering a new perspective on the program. This framework adds to the literature on evaluations of immunization disparities in determining whether evaluators can definitively attribute positive immunization outcomes in the community to the program and conclude whether it has potential in expanding or duplicating it to other similar settings, especially in other rural areas of the United States, and abroad, where routine immunization equity gaps are wide due to income, racial and ethnic diversity, and language barrier.

Smart cities are expected to provide residents with convenience via various agents such as CCTV, delivery robots, security robots, and unmanned shuttles. Environmental data collected by various agents can be used for various purposes, including advertising and security monitoring. This study suggests a surveillance map data framework for efficient and integrated multimodal data representation from multi-agents. The suggested surveillance map is a multilayered global information grid, which is integrated from the multimodal data of each agent. To confirm this, we collected surveillance map data for 4 months, and the behavior patterns of humans and vehicles, distribution changes of elevation, and temperature were analyzed. Moreover, we represent an anomaly detection algorithm based on a surveillance map for security service. A two-stage anomaly detection algorithm for unusual situations was developed. With this, abnormal situations such as unusual crowds and pedestrians, vehicle movement, unusual objects, and temperature change were detected. Because the surveillance map enables efficient and integrated processing of large multimodal data from a multi-agent, the suggested data framework can be used for various applications in the smart city.

This study aims to analyze the formation of Korean social welfare delivery system and its pathway, from which the pending issues are to be discussed on the organizations and personnel of the delivery system using the word 'social welfare' with its related discourse. Historical institutionalism is chosen as the perspective to explain path-dependent change and critical juncture, and various legislative data are used as the indicative signals for the discourse of 'social welfare'. The results of the study are as follows. First, the term 'social welfare' began to be institutionalized in Korea by the enactment of Livehood Protection Law(1961). Second, the policies by the year 1987 of expanding social welfare center and introducing social welfare professionals as civil servants form a critical juncture which makes the social welfare discourse realized as the institutional realities. Third, until the year around 2014, the system has not changed in the perspective of macro framework. Fourth, currently the system shows several signs of severe turmoil, which might lead to dismantle the system of 'social welfare' discourse. To conclude, this study shows the possibility of explaining organizations and personnel composing the social welfare delivery system by the usage of discourse analysis, treating it as an analytical entity.

Academic research of the social service delivery system is very limited. This paper checked on the status of research on current social service delivery system in order to explore new research and policy directions. Analysis study consisted of 79 pieces and the framework was divided into dimensional analysis, content analysis and analytical standards. Research on the papers of social service delivery systems showed from the initial stage of the policy discussion to the phase of the individual services. Summarizing the study is as follows. First, This studies confirmed that at this time the quality studies on social service delivery system is needed. Second, this indicates that right now, the government budget of social services and the data relating to social service agencies will be opened to the public for the expansion of social services studies. Third, to expand social services delivery systems research, it showed that social services demand forecasting research such as budget allocation, population characteristics, equality of public service and local information is needed. Finally, since the quality of service is reduced by the oversupply, the discussion of the entry regulations of social service providers is required.

This study is to identify the relationship in non-profit social welfare organizations(SWOs) between financial sources and service delivery. Especially the impact of the former to the latter is its main concern. For this purpose, gathered are the 1992, 1999 financial reports of those study organizations, and some qualitative data on a number of the organizations collected by the author is also used for verifying and interpreting the data. Gronbjerg's study(1992) provided an analytical tool for decomposing financial structure of human service organizations, and resource-dependency perspective was a theoretical framework for interpreting the impact of financial composition to service delivery. The findings are as follows: (1) Between 1992 and 1999, there was a noticeable change in financial composition among SWOs. Government subsidies has increased in terms of both amounts and percentages, for residential facilities 75% to 82% and for nonresidential facilities 37% to 47%. Funding from donations shows no abrupt changes, although absolute amounts were slight increasing. Fees were sharply decreasing, especially for the non-residential facilities which previously enjoyed them as valuable resources for preventing unnecessary influence from government. (2) The funding sources of SWOs and their strategies to acquire them has impact on service delivery. Although non-government fundings(donations and fees) were found to give elasticity to SWOs, various problems associated with acquiring them (i.e., changing the clientele) would prohibit SWOs from fully concentrating to those fundings. Meanwhile, government fundings are characterized as stable, and, as such, most of the SWOs prefers. Limited elasticity, red-tape, 'sacrifice of quality of service' over efficiency, etc. are referred to the problems.

Wireless sensor networks have been used in many applications such as marine environment, army installation, etc. The sensor data is very important, because all these applications depend on sensor data. The possibility of communication failures becomes high since the surrounding environment of a wireless sense network has an sensitive effect on its communications. In particular, communication failures in underwater communications occur more frequently because of a narrow bandwidth, slow transmission speed, noises from the surrounding environments and so on. In cases of communication failures, the sensor data can be lost in the sensor data delivery process and these kinds of sensor data losses can make critical huge physical damages on human or environments in applications such as fire surveillance systems. For this reason, although a few of studies for storing and compressing sensor data have been proposed, there are lots of difficulties in actual realization of the studies due to none-existence of the framework using network communications. In this paper, we propose a framework for reducing loss of the sensor data and analyze its performance. The our analyzed results in non-framework application show a decreasing data recovery rate, T/t, as t time passes after a network failure, where T is a time period to fill the storage with sensor data after the network failure. Moreover, all the sensor data generated after a network failure are the errors impossible to recover. But, on the other hand, the analyzed results in framework application show 100% data recovery rate with 2~6% data error rate after data recovery.

Despite its graceful bandwidth saving nature, IP multicast has not been successful in widely spreading and using. Challenging includes policy and technological issues such as inter-domain routing, multicast availability and reachability. Properly detecting and isolating the faults would be the first step to stabilize IP multicast. In this paper, we introduce a scalable multicast monitoring framework. To efficiently cope with multicast network and networking problems, it enlarges its monitoring scopes from collecting delivery statistics to verifying end-to-end multicast availability, reachability and interactivity. We carry out various networking experiments to verify the scalability and feasibility of the proposed framework.
