The Relational ranking method applies authority-based ranking in relational dataset that can be modeled as graphs considering also their tuples' values. Authority directions from tuples that contain the given keywords and transfer to their corresponding neighboring nodes in accordance with their values and semantic connections. From our previous work, ObjectRank extends to ValueRank that also takes into account the value of tuples in authority transfer flows. In a maked difference from ObjectRank, which only considers authority flows through relationships, it is only valid in the bibliographic databases e.g. DBLP dataset, ValueRank facilitates the estimation of importance for any databases, e.g. trading databases, etc. A relational keyword search paradigm Object Summary (denote as OS) is proposed recently, given a set of keywords, a group of Object Summaries as its query result. An OS is a multilevel-tree data structure, in which node (namely the tuple with keywords) is OS's root node, and the surrounding nodes are the summary of all data on the graph. But, some of these trees have a very large in total number of tuples, size-l OSs are the OS snippets, have also been investigated using ValueRank.We evaluated the real bibliographical dataset and Microsoft business databases to verify of our proposed approach.

Personality factors and ethical values are considered as vital element in social and professional life. This present research aims to explore the relationship between Personality and Job Satisfaction. Further, we tried to test the moderating effect of Islamic work ethics (IWE) in the relationship of Personality traits with Job satisfaction. Convenience sampling was used in defining sample as in Pakistan there is no data base which provides information regarding number of employees. Due to moderating variable the data has been collected from respondents who identify themselves as Muslim. To collect data from respondents Self-administered, close-ended questionnaires and e-questionnaire were used in this study and respondents were targeted in the normal working environment. Correlation and regression analysis was used to analyze the data statistically. The results of study indicated that neuroticism exhibits significant negative effect on job s atisfaction. Also, openness to experience, agreeableness and conscientiousness showed positive effect on job satisfaction. Whereas, extraversion exhibits no effect on job satisfaction and IWE has a negative effect on job satisfaction. However, the output indicates that IWE do not act as moderator in the relation of agreeableness and conscientiousness with job satisfaction moderation effect of IWE is observed between the relationship of neuroticism, extraversion and openness to experience with job satisfaction.

Cotton fabrics were treated with gelatin to improved their dyeability, color strength toward cochineal dye. Gelatin were used as the protein. Gelatin is containing a large number of hydrophilic groups. Pad-dry-cure method was used for the treatment process(10g/L concentration). The scanning electron micrograph showed the gelatin was deposited on the surface of cotton. Pretreated fabrics were mordanted with 10%(owf) alum. Then the fabrics were dyed with cochineal. Compared with original cotton fabric the K/S value with cochineal dyes was significantly improved on gelatin modified cotton. Treating cotton with 10g/L concentration gelatin offered higher cochineal adsorption. The dyeability of pH 4 yielded the highest color strength. In dyebaths of a ratio of ethanol and water such as; 10:0, 9:1, 8:2, 7:3, 6:4, 5:5, 4:6, 3:7, 2:8, 1:9, 0:10, fabrics were dyed. The ratio of ethanol and water had powerful effects on solution polarity. Cochineal dye uptake showed maximum value, when the proportion of ethanol and water was 9:1. Dyeing at increased temperatures and with increased time resulted in higher dye uptake and reddish-purple color(5RP). The washing fastness was 1-2grade, and the fastness to light was 2-3grade.

As a promising candidate for anode materials in lithium ion battery (LIB), tungsten trioxide ($WO_3$) and tungsten disulfide ($WS_2$) nanocrystals were synthesized, and their electrochemical properties were comprehensibly studied using a half cell. One-dimensional $WO_3$ nanowires with uniform diameter of 10 nm were synthesized by hydrothermal method, and two-dimensional (2D) $WS_2$ nanosheets by unique gas phase sulfurization of $WO_3$ using $H_2S$. $WS_2$ nanosheets exhibits uniformly 10 nm thickness. The $WO_3$ nanowires and $WS_2$ nanosheets showed maximum capacities of 552 and $633mA\;h\;g^{-1}$, respectively, after 100 cycles. Especially, the capacity of $WS_2$ is significantly larger than the theoretical capacity ($433mA\;h\;g^{-1}$). We also examined the cycling performance using a larger size $WO_3$ and $WS_2$ nanocrystals, showing that the smaller size plays an important role in enhancing the capacity of LIBs. The larger capacity of $WS_2$ nanosheets than the theoretical value is ascribed to the lower charge transfer resistance of 2D nanostructures.

This study aimed to investigate the effects and epidermis penetration system with polymer micelle of Red Pinus densiflora extract. In the antioxidant test, the total concentration of polyphenol compounds was determined to be $137.5163{\pm}7.70mg/g$ in ethanol extract, $133.956{\pm}1.57mg/g$ in hydrothermal extract. The DPPH radical scavenging effects were $95.29{\pm}0.15%$ in ethanol extract at 1,000 mg/L. Elastase inhibition rates were $100.00{\pm}2.85%$ in ethanol extract at 2,000 mg/L. The antimicrobial effect of the ethanol extraction was higher than that of hydrothermal extractions. In the epidermal permeability experiment, it was confirmed that the permeation of the polymer micelle containing the Red Pinus densiflora's ethanol extract and cell penetrating peptides was remarkable. Here, we confirmed that ethanol extract of Red Pinus densiflora displayed excellent the effects in antioxidant test and epidermis penetration system with polymer micelle. As a result, Red Pinus densiflora extract has potential to be used as a safe and natural cosmetic material in the future.

Pseudomonas sp. PAMC 29040 was isolated from a maritime tundra soil in Antarctica for its ability to degrade lignin and subsequently confirmed to be able to depolymerize heterogeneous humic substance (HS), a main component of soil organic matter. The draft genome sequences of PAMC 29040 were analyzed to discover the putative genes for depolymerization of polymeric HS (e.g., dye-decolorizing peroxidase) and catabolic degradation of HS-derived small aromatics (e.g., vanillate O-demethylase). The information on degradative genes will be used to finally propose the HS degradation pathway(s) of soil bacteria inhabiting cold environments.

The nuclear power plants in South Korea have been designed in accordance with the U.S. Regulatory Guide 1.60 (R.G 1.60) design spectrum of which the peak frequency range is 2-10 Hz. The characteristics of the earthquakes at the Korea nuclear power plant sites were observed to be closer to that of Central and Eastern United States (CEUS) than the R.G 1.60, which is a lower amplification in a low frequency range, and a higher amplification in a high frequency range. The possibility of failure for sensitive power plant components in the high frequency range has been considered and evaluated. In this study, in order to improve the reliability of nuclear plant and administrative control procedures, seismic tests of an emergency diesel generator (EDG) were conducted using a shaking table under both high and low frequency ranges. From the tests, oil/lubricant leaks from the bolt connections, the fuel filter and the fuel inlet were observed. Therefore, the check list of nuclear plant components after an earthquake should include bolt connections of EDG as well as anchor bolts.

The purpose of this study is to analyze the 'Brera Academy', worked between 1935-1940 at Milano in Italy. Giuseppe Terragni(1904-1943) is, as it is well known, one of the representative architects in the period of Italian rationalism architecture. In particular, his 'Casa del Fascio(1928~1936)' is evaluated as a representative work of this period. The research is based on original drawings and letters, mostly produced by G. Terragni or relative person and office of this work. Through analyze on the design process, the research tries to reveal Italian rationalist's design method and strategy, especially in the educational facility project. There are at least three deferent phases in the design process; in each phase, there are fundamental changes such as a structural system, relationships between the traditional garden and new building or spatial sequences. So, this study attempts to clarify the design methodology and strategy of the Italian rationalist in the design of educational facilities through analysis of the design process of Brera Academy.
