Hazardous work zones (i.e., hot, warm, and cold) are typically established by emergency response teams during hazardous materials (HAZMAT) calls but less consistently for fire responses to segment personnel and response activities in the immediate geographic area around the fire. Despite national guidelines, studies have documented the inconsistent use of respiratory protective equipment by firefighters at the fire scene. In this case-series report, we describe warm zone gas levels using multigas detectors across five independent fire incident responses all occurring in a large South Florida fire department. Multigas detector data collected at each fire response indicate the presence of sustained levels of volatile organic compounds in the "warm zone" of each fire event. These cases suggest that firefighters should not only implement strategies for multigas detector use within the warm zone but also include respiratory protection to provide adequate safety from toxic exposures in the warm zone.

Productivity of public organizations was far older due to issue more difficult to measure than private organizations. Unlike the private sector, the public sector is a diverse and sometimes conflicting objectives (efficiency, effectiveness, equity, democracy, etc.) exist, it is difficult to measure productivity in a single index. Many departments of government is intricately interrelated and sometimes produced by the joint efforts, it is difficult to allocate performance, incentives and accountability to among departments. And there is the difficulty of collecting data on the productivity indicators of public organizations. Despite these difficulties, we developed a productivity index system and measuring method to systematically introduce the concept of productivity in the local administration. In this paper, the productivity and the productivity index measurement practices of local governments conducted annually from 2011 on was deep into research. First, the report found examples of the governments of the developed countries, productivity measurement, then the way MOPAS(Ministry of Public Administration and Security) measure productivity index of local governments, success factors, the implications were in-depth analysis. Finally, in order to enhance productivity and competitiveness municipalities studied ways to take advantage of the productivity index.

This paper is a report on the user requirements analysis based on the survey performed during the February and March, 2002. The survey constitutes the preliminary stage of our research on the design of advanced public transportation system(APTS) in ITS service. A random sample of 60 responses were selected from the total of 300 replies that were received for our statistical analysis. We were able to identify what kind of information content Is mostly required by the public transportation users. Some useful guidelines as to how to design the APTS are provided as the conclusion.

The aims of automation efforts in libraries are the rationalization of interval work and improvement of user services. After a period of exclusive internal computer utilization, later voluntary contact with the computer (e.g., circulation control with self services), patrons of American libraries now have to go to a computer terminal if they want certain information. Online public access catalogs(OPAC) have been used in American libraries since the end of the seventies. But OP AC are accepted by patron only if they have a useful and flexible user interface. This paper briefly describes the use of online catalogs in different type of libraries, categories of user (user, non-user), aspect of catalog use in context with computer experience etc. The disscussion then focuses on the characteristics of the final report of online catalog use study of Council on Library Resources and user problems in searching, as reported in many other catalog use studies.

New epidemics of infectious diseases often involve health care workers. In this short communication we present a case report of a health care professional who became the first case of influenza H1N1 virus to be notified in the United Arab Emirates. There are several issues related to workplace considerations and general public health, including preventive measures, the need for isolation of the patient, dealing with contacts, return to work, and communication with the workforce.

Construction Technology Service is currently hardly managed due to failure to offer standard management system of service performance, company performance, and business evaluation in every Ordering Agencies. After Construction Technology Promotion Act is enforced in May 2014, Ordering Agency obligates them to report to Minister of Land and Transportation within 10 days upon contract/ amendment/ completion. In 2013, in advance to enforcement of this law, performance management system for construction technology service was developed for a test run. However this system only applies to main contractors while management and operation of subcontractors are unavailable that causes problems on connection and integration with Experience Management Trustee. Therefore, this research will establish systematic foundation that enables real-time information of service performance and evaluation of subcontractors to result standardization of performance and evaluation for public ordered services.

중안면부의 골절은 심미적으로나 기능적으로 많은 문제를 야기할 뿐아니라 두개부와 연관되어 뇌손상의 가능성을 가지므로 생명과 직접적인 연관을 갖는다고 할수 있다. 산업사회의 고도의 발달로 인하여 자동차의 보급이 증가하고 그에 따라 교통사고의 절대수가 증가하고 안면부 골절환자가 증가추세에 있다고 볼 수 있다. 때문에 구강악안면외과의사로서 중안면부의 골절에 관심을 기울여야 할 것으로 생각된다. 중안면부 골절 가운데 비골을 포함한 안와 근심벽의 쉽게 일어나며 골절에 포함된 해부학적 구조물들이 복잡하기 때문에 골절후에 기능적 이상이 쉽게 발생될 수 있다. 본 과에서 처치한 중안면 골절 환자중 비골을 포함한 안와 근심벽의 골절환자를 경험한 바 이에 보고하는 바이다.

As the second most populous province in Cambodia, Battambang also exhibits an increasing number of urban poor areas. This research focuses on the economic situation of slum areas in Battambang and how people in slum areas are affected by climate change. This research report describes socioeconomics of people living in slum areas in 4 villages in Battambang City. An investigation will be made on motivation of moving to slum areas, access to water, access to sanitation, access to electricity, transport and delivery, access to health care, access to education, security of tenure, cost of living in slum, literacy, and access to finance. We also explore the policy of the public sector toward climate change in Cambodia.

The Public Vehicle Routing Problem (PVRP) is to find the minimum total cost routes of M or less Public-Vehicles to traverse the required arcs(streets) at least once, and return to their starting depot on a directed network. In this paper, first, a mathematical model is formulated as minimal cost flow model with illegal subtour elimination constraints, and with the fixed cost and routing cost as an objective function. Second, an efficient branch and bound algorithm is developed to obtain an exact solution. A subproblem in this method is a minimal cost flow problem relaxing illegal subtour elimination constraints. The branching strategy is a variable dichotomy method according to the entering nonrequired arcs which are candidates to eneter into an illegal subtour. To accelerate the fathoming process, a tighter lower bound of a candidate subproblem is calculated by using a minimum reduced coast of the entering nonrequired arcs. Computational results based on randomly generated networks report that the developed algorithm is efficient.

The purpose of this study is to estimate the minimum optimal scale(MOS) of the self-employed health insurance associations. Considering the high proportion of operating expenses, the author have selected 254 regional health insurance associations eon the 1990 Finance Report of the self-employed health insurance programs. Both a quadratic function and a hyperbolic function were chosen for the analysis. The dependent variables are the average maintenance cost per insured person and per household, and the independent variables are the number of insured members and of household The minimum optimal scale was obtained from the differentiation of the quadratic function. Major findings are summarized as follows: 1. The M.O.S. was calculated as 166,174 members (27,442 households) for the rural self-employed health insurance associations and 258,462 members (75,446 households) for the urban. Providing that both the rural and urban health insurance associations would be integrated, the M.O.S. be found to become 231,687 members (68,101 households) 2. Compared with the optimal minimum scale, the magnitude of the current health insurance association found to be much smaller, less than half of the optimal scale. 3. In order to reduce the operating cost, it is necessary to enlarge the operational scale of self-employed health insurance associations.
