THE UNLUCKY NUMBER IN CULTURAL PERSPECTIVE OF JAPANESE SOCIETY
Authors: Suhartini Suhartini 
Published: December 2019

This article tries to reveal the cultural perspective of Japanese society on unlucky number, that is 4. Comprehending this phenomenon is needed by those who intend to cooperate or make relation with the Japanese in order to get better understanding. Library research and interview with native speakers of Japanese and Chinese are conducted in this research. The result shows that 4 is considered an unlucky number because linguistics link in the form of homophone or similarity of sound between the Japanese numeralia’s pronounciation of absorbed from Chinese, that is shi [ɕi] meaning ‘number 4’, and a Japanese root verb’s pronounciation shi [ɕi] of shinu [ɕinɯ] meaning ‘death’. Although today the number is often used in public, some Japanese still avoid it directly or indirectly. Direct avoidance is done by not using 4 or refusing anything related to the number. Indirect avoidance is done by using numeralia yon which is the synonym of shi, both of which mean 4.

Abstract
In this study, the effect of fortification of tiger nut milk with moringa seed on the microbial, nutritional and sensory quality of the local beverage was investigated. Fortification of tiger nut milk significantly (p ≤ 0.05) reduced the fungal load of the drink with 8.00 as against 17.00 in the control sample. The organisms isolated from the freshly prepared tiger nut milk blends were Bacillus subtilis, Micrococcus luteus, Saccharomyces cerevisiae, Aspergillus niger, Rhizopus stolonifer and Penicillum species. Further, fortified milk had higher moisture (78.51%), protein (2.97%) and lipid (2.01%) contents compared with the unfortified milk which had 76.83%, 2.11% and 1.45% respectively. Also, the ash, fiber and carbohydrate contents of the unfortified tiger nut milk were higher than that of the fortified tiger nut milk. Similarly, the fortified milk had higher level of all the minerals assessed than unfortified milk. In the sensory evaluation, tiger nut milk fortified with moringa seed had comparable rating to the unfortified milk in appearance, color, consistency and acceptability, but had a lower rating for taste and higher rating for aroma. These results suggest that moringa seed powder may be added to tiger nut milk to improve its nutritional quality.

Published: December 2019

Abstract
The atmospheric CO2 is now at the highest level seen (400 ppm) and the construction sector is responsible for 36 % of all greenhouse gases. One way to reduce this negative impact is to use more sustainable and environmentally friendly materials such as timber in the construction. To direct the sector towards this goal, the Erasmus+ project HiTimber (“Sustainable High-Rise Buildings Designed and Constructed in Timber”) was initiated in 2017. With the objective of developing an international and trans-disciplinary course in design, construction and management of sustainable high-rise timber buildings, project-based learning (PBL) was applied. The aim of the paper is to examine the effects of the PBL by examples and results from the HiTimber workshops. The presented results are the approbation of scientifically-practical results, derived from surveys conducted in 2018 and 2019 where 29 teachers and 45 students evaluated the PBL-based workshops. In general, all teachers and 85 % of students were satisfied with the PBL approach; the students were more engaged, motivated and successful in their studies. However, the transition from traditional teaching to PBL has its challenges and requires time, effort and strong commitment from both students and teachers to be effective.

Published: December 2019

Abstract
The productivity of real property depends on the efficiency of the property management technique. Building Information Modelling (BIM) is an emerging technique examined. The aim of the research is to explore the practicability of BIM for the management of public buildings (PBs) and the hindrances subject to the effective operation. The tasks of the research were to investigate the awareness level of BIM for management of PBs; to investigate the acceptance level of BIM as a property management technique; to explore the hindrances of BIM use for the management of PBs; and, to assess the suitability of BIM for management of historic buildings. Survey and descriptive methods were used in the research. One hundred and nine questionnaires were distributed and a total of seventy-eight was returned. Purposive sampling technique was used for the selection of the respondents. Stratified random sampling was used to select the public buildings, while clustered sampling was used for locations. The findings of the research showed a low level of awareness from the respondents; BIM was not in use; the acceptance of BIM was high but the hindrances were numerous. The research concluded that the use of BIM was practicable given adequate awareness and training. The research recommended a paradigm shift from the traditional property management approach to BIM strategy for the effective performance of PBs.

Published: December 2019

Abstract
The European Union has been highly emphasising the role of public procurement for innovation as a policy instrument that can be used to stimulate sustainable development. This development reflects and responds to improvements in social welfare, growth of entrepreneurship and of national competitive advantage. In the process of selection, the awarding tender public procurement institutions lack an overall approach for choosing the most advantageous and sustainable innovation alternative. To contribute purchasing of innovative solutions, the present paper elaborates a framework of innovation measurement and quality evaluation. Thus, it makes possible to assess proposals from different aspects and to choose the most valuable offer notwithstanding the lowest price criteria.
The paper studies the concept of public procurement, its pitfalls and prospects, dimensions of innovation definition and innovation added value assessment. The authors conducted expert interviews, which were analysed using an AHP method in order to set the most appropriate evaluation criteria indicator. The authors also designed the framework for assessing the quantitative and qualitative value of innovation proposals. The proposed approach is based on the analysis of innovation quality, added value, its potential impact and the sustainability of changes it produces.
Relationship Between Nursing Home Safety Climate and Caregivers’ Competence
Authors: Sepp Jaana , Järvis Marina 
Published: December 2019

Abstract
To provide quality healthcare, strong teamwork, safety commitment and collaboration between workers are needed. The aim of this paper is to analyse factors related to safety climate and professional competence among caregivers and to compare the results between different age groups in Estonian nursing homes. A Nordic Safety Climate Questionnaire (NOSACQ-50), measuring 7 dimensions of safety climate, was used in order to assess caregivers’ perceptions of the safety climate in Estonian nursing homes, on a sample of 233 caregivers. In order to supplement results from the safety climate study, a Caregivers’ Competence Questionnaire (CCQ) measuring 6 scales of the caregivers’ competences, their perceptions towards received education and safety-related procedures in nursing homes, was used on a sample of 241 caregivers. Results show differences between age groups of caregivers. The most experienced caregivers tended to have a better understanding of their specialty and more positive ratings of the dimensions of safety climate and safety commitment than younger age groups of caregivers. Result show that the age group with respondents born in the period of 1961–1970 gave more positive ratings of “Necessary skills, knowledge in living questions and caring activities” than did other groups of caregivers (mean = 4.46 and 4.41) and of “First aid” (mean = 4.47). The study sheds new light on the usability and applicability of the existing assessment tools NASACQ-50 and CCQ. Interventions to promote safety climate in the nursing homes should be tailored to the target group with a special focus on age and work experiences as attitudes and perceptions may differ among those groups.

Published: December 2019

Abstract
The purpose of the work is to assess the degree of inhalation damage of a person exposed to the toxic cloud of liquefied gas evaporation from a spill spot of various shapes. The mathematical model of liquefied gas spill evaporation which arose as a result of accidental destruction of the storage capacity and further dispersion of the gas impurity in the atmosphere surface layer was developed. The computational technology for determining the fields of conditional probability of human inhalation damage by a toxic gas based on a probit analysis is developed. The mathematical model takes into account the flow compressibility, complex terrain, three-dimensional nature of the dispersion process, and the presence of toxic liquid substance evaporation from the arbitrary spill spot with varying intensity. The model allows obtaining space-time distributions of the toxic gas relative mass concentration and inhaled toxidosis which is necessary to determine the fields of the human damage probability based on the probit analysis. For different ellipticity of the hydrogen cyanide spill elliptical spot the fields of probability of human mortal damage are obtained and the influence of spot ellipticity on the scale of the consequences of an accident of this type is analysed. The developed technology allows carrying out automated analysis and forecasting in the time and space of the damage probability of a person exposed to the toxic gas as an indicator of the safety of the technogenic object.

Published: December 2019

Abstract
Reducing energy consumption in industry has become an important aspect on a global scale. Energy efficiency is one way of reducing energy consumption and promoting competitiveness. Increasing energy costs, security of energy supply, emissions from energy production have shown that current freezer design solutions are not sustainable. The food industry has a common tendency, whereby energy costs are only of secondary importance, unlike other production costs, resulting in minimal monitoring of energy consumption. Electricity consumption for freezer operation amounts to 20 % of total electricity consumption. Within the framework of this study, electricity consumption for fish freezing and storing frozen fish and finished products, as well as the coefficient of performance (COP) for compressors and parameters affecting COP were analyzed. From the results it can be concluded that the specific consumption of electricity in freezing of fish is lower than that of frozen fish storage. The two-stage compressor COP ranges from 2.4 to 3.7, but the single-stage compressor COP ranges from 3.7 to 5.5. The pressure in the condenser and ammonia vapor temperature after the compressor is affected by the temperature of the water used to cool the condenser and compressors. As the temperature of the water used for cooling increases, the condenser and ammonia vapor temperature after the compressor increase, which in turn reduces the compressor COP.

Published: December 2019

Abstract
Economic performance of net-zero energy building/community (ZEB/ZEC) is an important factor that affects potential investors’ decision on installing renewable energy systems (RES). A reward-penalty mechanism (RPM) is proposed for accelerating the development of zero energy communities, which is developed without considering the reliability effect from RES generation. However, an investigation is deserved for the reliability effect of RES on building economic performance. A case study is therefore conducted based on an assumed community consisting of 20 family houses, in which the electricity load was collected by the smart meter for more than one year. The results show that the proposed RPM works efficiently under an ideal condition, while the costs of the community and its buildings are greatly increased when the effect of PV system reliability is considered. Specifically, the total cost of the community under 1.0ZEC design is 5 005 USD/yr in the first year, which increases to 11 341 USD/yr in the 25th year. By contrast, the total cost of the community under 1.2ZEC design is 5 243 USD/yr in the first year and increases to 9 607 USD/yr in the 25th year. It is believed that the results of this study can provide a progressive perspective for scheme makers and building owners in terms of its economic benefit. Development of enhanced RPM by considering system reliability will be investigated in our future work.
