  • Construction and operation of Germ Free Pigs' facilities are very expensive because pigs' rooms and other major rooms of the facility require germfree environments. Especially, running the HVAC system of aseptic facilities requires a lot of expenses. However, proper location and efficient shape of outlets/inlets for the ventilation of the room can reduce the excessive running cost. In order to do that, this study proposes alternative location and shape of ventilation outlets/inlets to the existing design pattern in germfree pigs' room. The design condition of this study is the maintenance of adequate temperature(24$^{\circ}C$, $NH_3$concentration level(below 1.5 ppm), and air stream speed(below .25m/sec) in the pigs' room for the summer and the winter together. As the Software Program, FLUENT(Ver. 6.2) has been used for the analysis of proposed ventilation patterns. In conclusion, wall inlets and ceiling inlet/outlet are advisable in summer, wall inlets and ceiling outlets is advisable in winter. As far as the shape is concerned, diffuser type for the ceiling outlet is desirable.

  • The fault diagnosis technologies may be applied in order to decrease the energy consumption and the maintenance cost of an air-conditioning system. In this paper, a fault diagnosis algorithm was developed by using a neural no-fault model and a dual fuzzy logic. Five different faults, such as the compressor valve leakage, the liquid line blockage, the condenser fouling, the evaporator fouling, and the refrigerant leakage of an air-conditioning system, were considered. The fault diagnosis algorithm was tested by using a fault simulation facility. Test results showed that the algorithm developed for this study was effective to detect and diagnose various faults. Therefore, this algorithm may be practically used for the fault diagnosis of an air-conditioning system.

  • The purpose of this study was to analyze the status of conservation and management of KIAHS(Korea's Important Agricultural Heritage System) by focusing on which of the conceptual and institutional characteristics and stakeholder activities, and to suggest improvement plans. The results were summarized as follows, first, insiders prioritize financial support and participate in plan execution and activities. Second, rural utilization and traditional agricultural succession activities and support are deficient. Third, administrators (intermediary) focuses primarily on KIAHS designation; ordinance enactment, manpower recruitment and other structural considerations are lacking. Fourth, the role of administrators (intermediary) is limited to operational funding and facility management support at the enforcement and activity stage. Fifth, outsiders besides visitors, such as the public or business enterprises, lacked participation methods. For the sustainable KIAHS, municipality must perceive agricultural heritage as a resource and recognize the importance, and treat it accordingly. The establishment of local-led conservation activities and movements must be considered in an enhanced investigation and excavation stage. The complementary policies that ensure continual support from experts from the first investigation and excavation stage to the final monitoring stage are necessary. The standards and regulations are necessary to achieve parity between conservation and maintenance of agricultural heritage, and its utilization.

  • This paper provides quantitative data that describes the evolution of the air quality in the Whale and Sea Museum, located in the Iwate prefecture, collected after the 2011 Great East Japan Earthquake and tsunami. The museum was damaged significantly by the disaster, and restoration works continued for over six years. The air quality in the temporary storage facility and museum was monitored during the rehabilitation process. Evaluation of air quality is carried out by gas chromatography- mass spectrometry, ion chromatography and high-performance liquid chromatography. The results showed that the characteristics of the chemical components differed depending on the measurement locations inside the building. The museum atmosphere tended to be alkaline as the airtightness increased because of the maintenance works at the entrance. It was also determined that it was necessary to study the intake/exhaust routes and to clean them according to the contamination degree. In Japan, there are recommended museum air quality standards for acetic acid, formic acid, alkali, and aldehydes. The results indicated that these standards should not be used as a reference for damaged museums. Furthermore, at the temporary storage facilities for to store the collections during the rehabilitation of the museum, solvents such as ethyl benzene, toluene, and xylene are initially abundant, although they can be reduced by ventilation, while other components such as 2E1H was confirmed in this case are likely to remain.

  • Objectives: The purpose of this study is to obtain the basic data for the development of maternal health care by analyzing the status and needs of service target persons in Timor-Leste. Methods: The subjects were selected through the non-probability sampling method applying the FGI. Researchers interviewed 3 maternal health service managers, 6 midwives at Gleno and Railaco Health Centers and 2 women between 15 and 45 years of age. Results: In the results of on-site visit of the delivery facility and the FGI, we found poor sanitation in delivery room, lack of medical equipment related to antenatal consultation and delivery. In the case of the health center manager, the public health center provides various maternity health services, but the lack of the staff has difficulty in providing the service and managing the subjects. Midwives asked for regular maintenance education. Women in child bearing age living in mountainous areas had poor access to delivery facilities and lack of awareness of delivery services. Conclusions: It is necessary to increase the maternity management rate through regular maternity and maternal health check service and application to maternal management database, to improve the sanitation of the maternity clinic in the public health center, to strengthen the midwife competency program.

  • The Continuous Ship Unloader (CSU) is an equipment that unloads freight from the ship docked in the port to the land. And the design target life time is designed to be 30 to 50 years, and it is classified as a semi-permanent large facility. However, cracks may occur due to structural defects, abnormal loads, and corrosion, and fatigue failure may occur before the design life is reached. In this study, we predicted the remaining life time of the main component of the CSU considering crack. And also proposed inspection cycle for maintenance of CSU based on the results of the remaining life time prediction. For this purpose, the structure, operational stresses of the CSU were analyzed and main members were selected. And tensile tests and fatigue crack propagation tests were performed with SM490YA and SM570TMC, which are used as main materials for CSU.

  • This study focused on the 'public architecture' of each local area as an alternative to local regeneration with a huge amount of funding. The starting point of this study is the public architecture that can be used as a strategic resource for local regeneration as a hub for communities for residents in the local area. The main content of the research is to identify the requirements of public architecture as a local regeneration hub and problems in the current public architecture management system. Based on results of the study, the following direction is to be presented for improvement of the public architecture management system to contribute to continuous local regeneration. The first results reveal there is a need to actively introduce measures to dualize facility maintenance and program operation. Secondly, the results show the participation of residents in public architecture management should be more active to reflect local demand. Thirdly, it is evident that the management entity should establish and implement goals and strategies toward local regeneration. Lastly, public architecture must strive to provide local community space.
