Authors: Gunawan Rahmat , Hammamiyah Ulinnuha , Fadillah Fahmi , Saleh Chairul , Sitorus Saibun
Published: July 2018

Artificial photosynthesis modelling of Ca-Pc-PDI complex Ca Phthalocyanine Perylenediimide), and dendrimer molecule using Density of Functional Theory (DFT) Method has been studied to showed the energy efficiency of these compounds in terms of electron transfer in photosynthesis. The Analysis of Ca-Pc-PDI and dendrimer compound and also chlorophyl has been done in all computations using the GAMESS-US software. The computations result in this research showed that the large wavelength complex compounds of Ca-Pc-PDI obtained was 138.3299 nm and energy efficiency obtained was 0.89 eV. The data analysis states that the absorption of harvest light energy of complex compounds Ca-Pc-PDI lies in the far UV spectrum. The other side, the polyphenylene dendrimer structure molecular orbital analyses it was found that the dendrimer was capable of electron transfers as indicated by the existence of HOMO and LUMO and result comparisons with chlorophyll. UV wavelengths of the polyethylene dendrimer and chlorophyll, respectively, suggesting that the polyphenylene dendrimer is capable of substituting chlorophyll in artificial photosyntheses. We can states from the result that these compound ability to be applied in the modeling of artificial photosynthesis as a material of energy absorption that mimics the workings of chlorophyll in terms of electron transfer in natural photosynthesis process. Keywords: Artificial photosynthesis modelling, Ca-Phthalocyanine-Perylenediimide complex, and dendrimer molecule

Competitividade internacional do Brasil à luz da fragmentação da produção e das cadeias globais de valor
Authors: Hermida Camila do Carmo , Xavier Clésio Lourenço
Published: July 2018

Este artigo desenvolve uma análise pioneira da competitividade das exportações brasileiras no período 1995-2011, ao considerar o fenômeno das cadeias globais de valor (CGV). Calcularam-se os índices de competitividade market share e vantagem comparativa revelada (VCR) pelas vias tradicionais e por meio de medidas de valor adicionado, assim como índices de participação e posicionamento nas CGV. Para tanto, utilizou-se uma nova metodologia de decomposição matemática das exportações (KOOPMAN et al., 2014) e indicadores estimados por meio da matriz de insumo-produto global World Input Output Tables (WIOT). As análises demonstram que os índices tradicionais tendem a subestimar o desempenho de países localizados a montante nas CGV, como o Brasil, mas nas categorias “produtos primários” e “manufaturas de baixa-tecnologia” percebem-se uma superestimação dos índices tradicionais e uma queda das vantagens comparativas reveladas do país.

Published: July 2018

On 5 May 2014, a Mw 6.1 earthquake occurred near Mae Lao (north Thailand), which damaged and disrupted healthcare services in the epicentral region because of structural and nonstructural damages. After providing a general summary of the observed ground motion and overall damages, a short description of the local healthcare system is addressed. Specific descriptions of the observed structural and nonstructural damages are provided based on a series of field surveys conducted between one and nine months after the mainshock. Although the observed structural damages were minimal, sustained nonstructural damages decreased the functionality of healthcare services for several weeks. Until recently, building regulations in Thailand and many other countries have aimed to preserve the structural integrity of buildings, and few studies have considered the seismic resistance of nonstructural components, particularly at hospitals. In addition, emergency planning should set functionality goals and develop plans for reaching them. This should include determination of the performance level expected of hospital buildings, medical equipment, and utility services to guarantee hospitals’ functionality during major disasters.
Calculation Model of Soil Dam Wash-Away Due to Overflow
Authors: Bohaslauchyk P. M.
Published: July 2018

Water flow over soil dam crest causes its fast failure. Break-through wave being formed in dam ebb side leads to drastic economic and social consequences. Accuracy in calculation of the break-through wave parameters depends on the accuracy of discharge hydrograph construction in the dam erosion site. A calculation scheme for soil dam wash-away due to overflow has been devised on the basis of the experimental data. Wash-away process is divided in two stages in accordance with the devised scheme. Wash-away of the downstream toe occurs at the first stage. The crest level from the side of upstream edge remains constant. Intensive crest lowering is observed at the second stage. The eroding body is considered to have a shape of a round-crested weir. In such a case the washed-away massif has a form of nappe-shaped crest profile. A mathematical model has been developed on the basis of this scheme and according to this model equations of deformation and flow motion are considered simultaneously. The model is consistent in a good way with physical erosion pattern during fast flood rise and when the erosion width is known; the model is recommended for calculation of breaching sections in reserve water outlets. In general case and when the width is unlimited (three-dimensional problem) calculation formulae have one more unknown variable that is flow width within the erosion site. The paper describes peculiar features in physiccal erosion pattern for such case and a number of the known formulae for determination of the erosion have been given and analyzed in the paper. The equation which fits in a good way in the proposed mathematical model has been chosen, and it provides the possibility to adapt the model for three-dimensional erosion conditions. Calculations made in accordance with the proposed methodology make it possible to construct discharge hydrograph in the dam erosion site.
Systematic Analysis of Indicators for Socio-Economic Security
Authors: Shvaiba D. N.
Published: July 2018

Conducting a systematic analysis of indicators for socio-economic security it is necessary to point out that fundamental groups of characteristics pertaining to socio-economic security include the following indicators: social standard and quality of living, degree of socio-economic system security, level of national financial independence, situation with management system and provision of socio-economic security. All the mentioned and some other indicators have something in common while ensuring socio-economic security and, for this reason, it is important to keep their balance and coherence. Evaluation of socio-economic security for a macro-system can be implemented among other tasks while using matrix method. According to this method it is possible to evaluate a possibility of threat appearance due to changes in a specific indicator, level of impact on national security, duration and time rate of changes in unwanted manifestations. The matrix makes it possible to classify those dangers when there is a possibility of an unsafe situation occurrence to such extent that it is required to undertake urgent measures to improve the situation and take special actions. The proposed method demonstrates visible results and it is considered as a statistical method of analysis. The given method presents rather good results while making smooth changes in evolutionary characteristics of the system. Monitoring horizon of these models is 1–2 years. In this context it is necessary to take into account that the proposed method is hardly suitable in the case when there are prompt changes in characteristics from one group of indicators to the other one. This is due to the fact that statistics of past periods has been applied and it characterized the given system which was under completely different circumstances at that moment. If this is the case then there is a discrepancy in creation of methods at all levels of socio-economic systems and these methods adequately take into account dynamics of changes in the system.

Intellectual capital performance of regional development banks in Indonesia
Authors: Umanto  , Wijaya Chandra , Wahyudi Atmoko Andreo
Published: July 2018

Studies related to intellectual capital, particularly in banking sector, are basically focused on the relationship between intellectual capital performance and bank performance. In con¬trast to previous studies, this study analyzes the intellectual capital performance of regional development banks throughout Indonesia to develop performance through management of efficiency and productivity. The population and sample in this study consist of 26 regional development banks in Indonesia for the period 2007–2013. The management of efficiency is measured using the ratio of operating expense to operating income (BOPO), while the management of labor productivity is measured using the ratio of labor expenses to total operating expense and income level. At the theoretical level, this study is expected to fill the gap for the assessment of intellectual capital performance of banking institutions with unique characteristics such as regional development banks. To analyze intellectual capital performance, VAICTM method developed by Pulic (1998, 2000, 2004, 2008) is applied. The findings show that the intellectual capital performance of regional development banks is in the category of common performers. Finally, regional development banks need to focus on the importance of strengthening intangible resources directly affecting banking management in terms of strengthening information technology, positioning, and management competence, as well as organizational culture and working climate.

Authors: Pimonenko Tetyana , Lyulyov Oleksii , Chygryn Olena , Palienko Maksim
Published: July 2018

The paper deals with the analysis of methodology of Environmental Performance Index. The authors analyzed and systematized the main existing integrated indices, which were used for evaluation of environmental, social and economic situation in the countries. The authors allocated the environmental performance index as a basis for analyzing the environmental policy of the country. In this direction, the authors analysed the main features, structure and indicators of environmental performance index. The authors allocated the world-leader countries with huge level of CO2 emissions. According to the results, the authors aproved that these countries should improve their environmental policy. Accordingly, they occupied less position in environmental performance index. For the purpose to analyze the relation between ecological, social and economic welfare, the authors analyzed score of sustainable development goal index, social progress index and gross domestic product per capita. The comparison analysis of findings showed that countries with good position on environmental performance index have the strong position on sustainable development goal index and social progress index. The authors suggested that Ukraine should orient to the EU countries with purpose to improve the environmental policy.

Authors: Souri Mahsa , Shakeri Alireza
Published: July 2018

Background:

Dittrichia graveolens (L.) is a strongly aromatic plant distributed in Mediterranean
regions. This research concerns the optimization of the Total Phenolic Content (TPC) and the Total
Tannin Content (TTC) of Dittrichia graveolens (L.) extracts using Response Surface Methodology for
Ultrasound Assisted Extraction (UAE) and Microwave Assisted Extraction (MAE). Central Composite
Design (CCD) was used to evaluate the effect of the solvent concentration and the extraction time, in
different methods on TTC and TPC. The antioxidant activities and antibacterial activities were
evaluated.

Methods:

The plant extracts were prepared using maceration, microwave and ultrasound assisted
extraction. TPC and TTC were measured using Folin-Ciocalteu method. The antioxidant activities
were studied using DPPH reagent and disc diffusion method was used to study the antibacterial
activities.

Results:

This study showed the optimum condition for UAE was 49.96% methanol concentration and
11.2 min sonication, while for MAE was 55.44% methanol concentration and 2.26 min microwave extraction.
It also indicated that MAE was the most effective method in comparison to UAE and maceration.
The antioxidant activities of MAE extract (IC50=7.7mg/mL) were more than UAE extract
(IC50=21.5mg/mL) and maceration (IC50=32.3mg/mL).

Conclusion:

As a conclusion, it was indicated that MAE was the most effective method. The higher
total phenolic content caused higher antioxidant activities as MAE extract had the highest antioxidant
activities. The antibacterial test showed the great potential of this plant as an antibacterial compound
resource against different bacteria.
Maximized Extraction of Flavonoid Luteolin from V.negundo L. Leaves: Optimization Using Box-Behnken Design
Authors: Abidin Lubna , Mujeeb Mohammad , Mir Showkat R.
Published: July 2018

Background:

Luteolin is a flavonoid unveiling various therapeutic activities, found in Vitex negundo L. Thus, there is a need to present process parameters at which maximum amount of luteolin can be extracted from V. negundo L. leaves in “one-run”.

Objective:

Response surface methodology (RSM) was employed for optimizing the process parameters for the extraction of luteolin from V. negundo L. leaves. The study also compared the efficacy of various traditional and modern extraction methods for luteolin extraction.

Methods:

Extraction conditions (solvent to drug ratio, extraction temperature and extraction time) were optimized by RSM, Box-Behnken Design (BBD). Quantification of luteolin in various extracts was done through High Performance Liquid Chromatography (HPLC).

Results:

Hot solvent extraction by reflux technique stood out to be the best technique and methanol was found to be the most effective solvent for luteolin extraction.Through the use of BBD, the optimal conditions for luteolin extraction were established as: solvent to drug ratio- 17.7 mL/g, extraction temperature- 55.5°C and extraction time-2.04 hours. Under such conditions 7.32 %w/w of luteolin was yielded which was close to predicted value of 7.29 %w/w.

Conclusion:

Reflux technique stood out to be the best among all the studied modes of extraction and methanol proved to be the most effective solvent. Moreover, all the three variables significantly affected the luteolin extraction. Our study shows the applicability of a statistical technique, RSM in phytocompound extraction field. This makes the optimization technique cheap and less laborious than the traditional optimization method.

The aims of this study were 1) to determine whether the Compare software Comparison% score provided appropriate feedback for preparation depth on a non‐anatomical tooth and 2) to define an acceptable tolerance for use in calculating the Comparison% for virtual assessment of cavity depth on a non‐anatomical mandibular first molar. Forty‐six non‐anatomical ivorine teeth with laser‐marked outlines on their occlusal surfaces were used for this study. One tooth was prepared at a 1.5 mm depth, approved by participating faculty at a U.S. dental school, and served as the standard preparation. The remaining teeth were divided into three groups (n=15 per group) for cavity preparation depths of 1 mm, 1.5 mm, and 2 mm in the laser‐engraved external outline. Teeth were prepared using an electric handpiece with a 330 bur and a hatchet. Virtual images of the standard and experimental tooth preparations were recorded using an intraoral scanner. Virtual comparison software was then used to superimpose a three‐dimensional (3D) image of each experimental preparation on the 3D image of the standard preparation. The software calculated comparison surface percentage values (Comparison%) at a 100 and 200 micron tolerance for each specimen. Two‐way mixed linear models (α=0.01) were adopted to compare outcomes for the two levels of tolerance for teeth with different depths of preparation. Using a tolerance level of 200 μm, Comparison% scores for the acceptable preparation depth of 1.5 mm were found to be significantly different (p<0.01) from those of the unacceptable 1 mm and 2 mm depth preparations. These findings suggest that virtual comparison software may be used to assess an acceptable depth for cavity preparation within a defined external outline.

The population in this study was 308 people with a sample of 75 employees, sampling technique using slovin method. The analysis technique used in this research is path analysis technique (path analysis) using SPSS. From the results of the study found organizational justice has a positive and significant effect directly on organizational commitment. Organizational justice has a positive and significant impact directly on job satisfaction. Organizational justice with job satisfaction as intervening variable has a positive and significant effect on organizational commitment. The direct impact of organizational justice on organizational commitment is greater than indirect influence through job satisfaction variables. Thus it can be interpreted that job satisfaction does not have an indirect effect of organizational justice on organizational commitment. So it can be concluded that job satisfaction is not proven as intervening variable.

In the life cycle theory of the company, it is stated that the Company which is at the established stage has the ability to make money beyond its ability to find profitable investment opportunities. The Company will distribute cash flow optimally to stakeholders in the form of dividend payments. The purpose of this study is to examine the effect of retained earnings ratio (proxied with retained earnings to total equity) on the probability and rate of dividend payments based on the life cycle of the firm. Companies listed on the Indonesia Stock Exchange period 2012 - 2016 are designated as research objects. Meanwhile, the sample is selected using criteria considered by the researcher (judgment sampling). Hypothesis testing is done by using the statistical method that is probit and tobit regression. The research findings show that retained earnings have a positive and significant effect on the probability and rate of dividend payments. However, the results of the study do not show significant evidence that retained earnings have a stronger effect on the probability and firm level of paying dividends.
