  • There are many economic and operational reasons to integrate fire alarm signaling system with other building automation system. Integration of this requires open network with for the standard communication protocol and careful design practices. The important point for this is also the development of intelligent control modules for replacing the conventional zone adapter in fire system. Therefore, this paper proposes an new conceptual design of the open distributed fire alarm signaling system for the integration of BAS, a new intelligent control modules with LonTalk protocol and a new control modules for power line communication. Newly proposed additions to LonWorks network make it very well suited for integrating fire systems with other building automation sub-systems and another BAS with low cost. Additionally, it is very important that best design practices, test procedures and building codes need to be modernized to accommodate integrated building systems.

  • Purpose: This study assesses the marketing practices and value-added fish products under the Coral Reef Rehabilitation and Management Program (COREMAP) in East Indonesia. Research design, data and methodology: This study gathered qualitative and quantitative data through i) focus group discussions (FGD) with fishers, traders and COREMAP officers, ii) surveys and iii) interviews with fishermen and traders. This study surveyed 714 households (365 in COREMAP and 349 in non-COREMAP) and 33 traders (17 in COREMAP and 16 in non-COREMAP) using structured questionnaires between January and March 2016. This study used Shepherd's Index to estimate the marketing efficiency for each stage of the marketing channel. For value-added fish products, the value is determined by the difference between processed output and the raw product used. Results: Marketing cost in the non-COREMAP area was more efficient than in COREMAP as indicated by lower operational cost and higher selling price. However, no value-added fish products were produced in the non-COREMAP area. This study noted a lower catch in COREMAP area, which implies COREMAP program successfully reduced fishing pressure. Conclusions: This study identified poor infrastructure and the limited market as the major problems in developing value-added fish products in both COREMAP and non-COREMAP area.

  • There are typically two categories of Flight Test Programs- commercial and military. Commercial flight testing is conducted to certify that aircraft meets all applicable safety and performance requirements of government certifying agency. Military programs differs from commercial in that the government contract with the aircraft manufacturer to design and build an aircraft to meet specific mission capabilities. The final phase of military aircraft flight test is the Operational Test(OT). OT is conducted by a government-only test team with the dictate to certify that the aircraft is suitable and effective to carry out the intended mission. This paper presents the current trends of military aircraft airworthiness certification using civil aircraft certification practices.

  • While Korean construction companies are adapting themselves to rapidly changing business landscape at home and abroad, intensifying competition among competitors in local as well as global market deteriorates the profitability of construction industry, which leads to another problem. In response to such challenges, many construction companies continue to innovate their business portfolio and organization structure, with strong commitment to business process innovation. Furthermore, they need to analyze the productivity of project site management manpower overhauling business processes systematically and develop effective alternative strategies. This research aims to analyze the productivity of project site management manpower. Current operational practices of construction site organizations have been analyzed with focus on large construction companies in Korea and data gathered from project sites have been analyzed from a wide range of perspectives, In so doing, this research is expected to provide basic inputs for any subsequent attempt to estimate proper resource requirement for site management tasks in construction projects and analyze the management productivity of such resources by enabling construction companies to better understand the current operational status of site organization.

  • In this paper, a method that dynamically adapts the traffic flow of automated guided vehicles (AGVs) used in automated container terminals to the changing operational condition is presented. In a container terminal, the AGVs are vulnerable to traffic congestion because a large number of AGVs operate in a limited area. In addition, dynamically changing operational condition requires the traffic flow of AGVs to be continuously adjusted to keep up with the change. The proposed method utilizes a genetic algorithm to optimize the traffic flow. Exploiting the dynamic nature of the problem an approach that reuses the results of the previous search is tried to speed up the convergence of the genetic algorithm. The results of simulation experiments show the efficiency of the proposed method.
