Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

Volumetric Content

The disastrous Chi-Chi earthquake struck Taiwan on 21 September 1999 and resulted in the creation of more than 20 million cubic metres of demolition waste, which was stored temporarily at several sites. To reduce the site clearing costs, the inert materials (concrete, brick, pottery, and fines) in the wastes should be reclaimed and recycled immediately; but most of their properties were not known. Therefore, this study investigates the properties of demolition wastes, including inert materials, coarse portions, and fines obtained from two earthquake demolition waste storage sites (Puli and Tali) and one normal urban construction waste storage site (Taichung). It is found that the volumetric content of inert materials from earthquake demolition waste is about 96%. Such inert material is classified as having an excellent subgrade rating and can be reused as subbase and base soils. The abrasion level of the coarse portions of inert materials from the three sites meets the required level of coarse aggregate according to Standard Taiwan Code CNS-490. On the other hand, the maximum dry unit weights of fines of inert materials from the three sites are greater than 14.7 kN/m3, and their shear strengths are higher than that of the same classification group (SW–SM) of natural soils, so they can be reused as construction soils.

Energy regenerative suspension can transform the shock energy produced in the driving process into electrical or hydraulic energy. This paper proposes a new hydraulic electromagnetic energy regenerative suspension design, and makes a comparison with the other two energy regenerative suspension designs by studying their structures and working principles, and makes an evaluation system by using fuzzy comprehensive judgment. According to the importance of the evaluating indexes, their subjective weights are gotten by using analytical hierarchy process (AHP); according to the performance statistics data, their objective weights are gotten by using entropy method; the general weights can be gotten from the subjective and the objective ones; and the evaluating value of suspension comprehensive performance can be calculated according to the general weights and the performance statistics data of evaluating indexes. The result reveals that the hydraulic electromagnetic energy regenerative suspension design has obvious advantages and is the most feasible design.

In this study, we chose 12 commonly available paper towels from the local market. The compression properties of the paper towels were examined by Kawabata Evaluation System for Fabric (KES-F). Three compression properties namely: (i) compressional linearity (LC), (ii) compression energy (WC) and (iii) compressional resilience (RC) were examined. The experimental results revealed that the compression properties varied within the different paper towels. RC vlaue was used as the key property for discussing the compression properties of paper towels. When different compression properties were correlated and analysed, it was found that no relationship was noted within different compression properties. On the other hand, there was not significant statistically relationship between weight and thickness to RC. It is hope that the results from this study can help the indurstry to improve the compression properties of paper towels for local market.

Different motor interventions have been widely investigated in balance control in elderly. However, it is not yet clear which type of motor intervention promotes improvements in balance control systems in the elderly. The aim of this study was to compare different motor interventions of the balance control system in elderly. Fifty-six elderly people participated in the study, distributed in sedentary group (SED), gymnastic group (GG), yoga group (GI) and stretching group (GA). Participants were evaluated using the Balance Evaluation System Test (BESTest) tool, designed to evaluate six items of balance control systems. The variables analyzed in the study were the scores obtained in each of the BESTest items. The results showed that GG and GI presented higher values in BESTest compared to the SED group. Even more, for the item gait stability and stability limits presented higher values compared to the other BESTest items. The conclusion of the study is that elderly gymnastics and yoga practitioners, modalities offered by the Exercise Orientation Service (SOE) can promote benefits to the balance control system in elderly.Keywords: BESTest, balance, elderly, motor intervention.

The Impact

This paper analyses the impact of the common European criteria on the Less Favoured Areas (LFA) delineation in the Czech Republic (CR) and compares it with currently used point evaluation system. Further, it compares the advantages and disadvantages of both delineation systems from various points of view and concerning the needs of common agricultural policies. In the Czech Republic, a system of point evaluation of the agricultural land productivity based on the Evaluated soil-ecological units (ESEU) is used for delineation of the other than mountain LFA since 2001. Within the programme period 2014–2020, the European Commission proposes to delineate the other than mountain LFA using a single set of criteria, common for all the member states. Some criteria of the natural handicap proposed by the European Commission (EC) can be derived directly from the ESEU five-cipher code and from the soil maps. The comparison clearly shows that the current Czech system of point evaluation of the productivity of agricultural land can express better the influence of worse soil and climatic conditions on the limitations of the agricultural use of the land than the system proposed by the EC. Additionally, the ESEU point evaluation can express also the effect of simultaneous influence of more factors, which may thus increase or decrease the final ESEU point values. Conversely, it is necessary to remark that the land quality evaluation based on ESEU is rather complicated and not easily understandable for the wide public. Also, it cannot be applied in all the EU countries.
