PURPOSE: The main objective of this study is observing the effects of the functional postural trunk exercise (FPTE) on deep cranio-cervical flexor (CCF) muscle endurance applied on neck pain patients suffering from the acute whiplashassociation disorder (WAD). METHODS: The study was tested with 47 patients with neck pain. All patients were equally treated with the ordinary therapy, only experimental group (n=23) was treated with FPTE: assumption of an upright lumbo-pelvic and spinal postural position, adding a neck lengthening manoeuvre in addition. Patients attended physical therapy for 3 times a week, for 4 weeks. Visual analogue scale (VAS) for pain, neck disability index (NDI), range of motion (ROM), were recorded both before and after the intervention. Also muscle activity in the CCF test was employed to analyze the changes between before and after. RESULT: After 4 weeks of training intervention, a remarkable increase in muscle endurance, rotation, extension ROM (p<.05) and decrease in pain and NDI (p<.05) in both groups. Further, the differences between groups were muscle endurance (F=60.350, p<.01), pain, and the left rotation ROM (p<.05). CONCLUSION: From the results, the experimental group had significant the increase in muscle endurance, and the significant decrease in pain. Whilst further research in this category is necessary, these observations suggest that applying exercise in early diagnosis can be of help to treat the neck pain patients suffering from the WAD.

Building energy performance assessment tools such as ECO2 and BESS used for the implementation of energy policy were developed on the basis of the calculation algorithms specified in ISO 13790 monthly method. Although the algorithms are applicable, the accuracy depends on the technical data factors including utilisation factors required for the calculation. Utilization factors used in current tools have never been verified. This study is to assess the applicability of the utilisation factors and to identify the error ranges against the results of detailed simulation program, Energy Plus. The analysis results show the error ranges from 12.16% to 117.86% for the cooling load and 9.86% to 97.26% for the heating load depending on the thermal property, climate and orientations.

Building energy performance evaluation tools such as ECO2 and BESS are now used for supporting building energy policy. ISO 13790 monthly calculation method adopted in the tools has, however, not been assessed thoroughly in terms of validity. The purpose of this study is to evaluate ISO 13790 monthly method for heating/cooling load calculation. Comparison analysis were carried out between ISO 13790-based model and detailed simulation tool (Energy Plus) model at intermittent and continuous operation.
