The problem of threat detection in an unstructured environment is considered. Three systems, comprising of robots and sensors, are proposed to form a system of systems (SoS) to find a solution to the problem. System interactions are defined to provide a framework for formulation as an SoS optimization problem. Different cost and objective functions are introduced for optimization of local criteria. Using different weights, a linear combination of the local cost and objective functions is obtained to propose a global objective function. An algorithm is suggested to find an optimum value for the global objective function leading towards optimization of the SoS.

Aims & rationale/Objectives : To identify barriers to the full implementation of new guidelines regarding school canteen menus launched by The Victorian Education Department in May 2004.
Methods : A self-administered questionnaire was sent to principals, business mangers and canteen managers of 13 secondary schools in South West Victoria covered by The Greater Green Triangle area (response rate 59%). The questions explored the canteen's role, operation, staffing and profits; existence and content of canteen policy; enablers and barriers to the sale of healthier foods; introduction and promotion of healthier foods; and perceived implications of banning less healthy foods.
Principal findings : The study identified several barriers to implementing healthy menus in school canteens, these being largely consistent with those found in other studies. The majority of schools reported they were making attempts to follow the guidelines for school food services, but were experiencing difficulty in proceeding to full implementation. The barriers identified through the study were student preference for less healthy options, concerns about profitability, lack of policy or its active communication and promotion at the school level and competition from other food outlets.
Discussion : There was evidence that healthy foods had not been actively promoted, suggesting that identification of student preferences as a barrier was based on perception rather than observation. The Victorian guidelines are effectively voluntary, with no accountability measures in place.
Implications : Research needs to be conducted to provide reliable and tested information about factors which impact on student choice. Schools would benefit from specialised assistance to formulate business plans for contemporary canteens selling healthy food and a clarification of government policy.

Based on the analysis of the basic principal of land reservation system of small and medium-sized cities, this paper gives detailed discuss on many problems which exist during the process of land reservation system, such as unclear function position of land reservation organization, single capital resource, unfair land compensation standard and incomplete urban design. It also submits the proposal—choosing one scientific model, establishing suitable organization, opening more channels for raising funds, and setting up reasonable land compensation standard to unify the land reservation in small and medium-sized cities, improve the efficacy of reserve departments, adjust and standardize the land market in order to promote the healthy development of small and medium-sized cities in the long term.

The objective of this research is to model and analyze candidate hull configurations for a low-cost, modular, autonomous underwater robot. As the computational power and speed of microprocessors continue to progress, we are seeing a growth in the research, development, and the utilization of underwater robots. The number of applications is broadening in the R&D and science communities, especially in the area of multiple, collaborative robots. These underwater collaborative robots represent an instantiation of a System of Systems (SoS). While each new researcher explores a unique application, control method, etc. a new underwater robot vehicle is designed, developed, and deployed. This sometimes leads to one-off designs that are costly. One limit to the wide-scale utilization of underwater robotics is the cost of development. Another limit is the ability to modify the configuration for new applications and evolving requirements. Consequently, we are exploring autonomous underwater vehicle (AUV) hull designs towards the goal of modularity, vehicle dexterity, and minimizing the cost. In our analysis, we have employed 3D solid modeling tools and finite element methods. In this paper we present our initial results and discuss ongoing work.

Aim
This study examined the effect of an education intervention on emergency nurses’ decisions related to oxygen administration.
Method
A controlled pre-test/post-test quasi-experimental design was used. The intervention was a written self directed learning package. Outcome measures were (i) factual knowledge measured using parallel form multiple choice questions (MCQs) and (ii) clinical decisions measured using parallel form MCQs, parallel form patient scenarios and clinical practice observation.
Results
Eighty-eight nurses from 4 Melbourne EDs participated in the study (control group: n = 37 and experimental group: n = 51). Subgroups of nurses from the experimental group also participated in the patient scenarios (n = 20) and clinical practice observation (n = 10). Emergency nurses’ knowledge increased as a function of education. Both patient scenario data and clinical practice observation showed decreased selection of nasal cannulae, increased selection of air entrainment masks and a trend towards selection of higher oxygen flow rates following education.
Conclusions
Evaluation of educational interventions in nursing should focus on identifying strategies that enhance learning in a clinical environment, are valid in terms of the clinical context and culture in which they are being used and most importantly, produce sustained improvements in actual clinical practice.
