Currently, interest on physical distribution is increasing due to burden of oil cost increases as oil price rises day by day. As interest grows, there are number of studies have been conducting on saving the cost of distribution. On the other hand, number of study on service of distribution is insufficient. Actually, subject of service of physical distribution have been studied by number of survey organizations, research organizations and mass media. Although, configuration for each organization is different from each other and it is hard to measure objective satisfactory factor of customers. This means needs for constructing standardized measuring tool as well as research on measuring service quality of distribution is not active. Therefore, this research is to compare and analyze compatibility of service quality measuring using SERVQUAL and SERVPERF and trying to clarify differences affected by importance service quality by each level to actual service quality. Also, this research is to make basic and standardized measuring model to improve quality of physical distribution especially using analysis of service quality and customer satisfaction of pallet pool service which contributes rationalization of distribution and reduce the cost by standardizing specification and size of pallet, allowing sharing of pallet. To conduct this research, case study of a company A is used where it is in a pallet pool business. Using this example, the goal is to give help on pallet pool business a strategic exercise if the business by point out major factors that affect customer satisfaction by collecting customer assessment along with examination of SERVQUAL and SERVPERF in measuring service quality if pallet pool service.

Purpose - Most past studies related to this focused on the physical attractiveness of service employees, but this study emphasizes the social attractiveness and not just the physical attractiveness of employees. Therefore, the purpose of this study is to first categorize attractiveness as physical attractiveness and social attractiveness and to examine the impact of physical attractiveness on social attractiveness for service industry employees. Secondly, this study aimed at verifying the impact of physical attractiveness and social attractiveness on interpersonal trust. Third, it aimed at revealing the impact of interpersonal trust on customer satisfaction, as well as satisfaction on loyalty. Research design, data, and methodology - Questionnaires were distributed to customers that used beauty salon services, among the various service industries, to verify the hypothesis of this study. Also, hypothesis was analyzed with the structural equation method using Amos 20.0. Results - When presenting the results on verifying the research hypothesis, it was found that physical attractiveness had a positive impact on social attractiveness. Second, while physical attractiveness did not have a positive impact on interpersonal trust, social attractiveness was found to have a positive impact on interpersonal trust. Such results show that in forming interpersonal trust, social attractiveness was more important than physical attractiveness for service industry employees. This result is in contrast with the results of past studies, but it is different in that previous studies suggested only physical attractiveness and did not present social attractiveness in the hypothesis. Third, it was found that interpersonal trust had a positive impact on satisfaction, while satisfaction did not have a positive impact on loyalty. Conclusions - The biggest implication of this study is that it presented social attractiveness, which was rarely dealt with in past studies. Also, this study is significant in that it examined the relationship of physical attractiveness and social attractiveness. The results of this study show that in the service industry, the role of human elements such as service employees is important and that in addition to physical attractiveness, social attractiveness in the course of interaction such as communication with customers can also be an important strategic element.

This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

The purpose of this study was to provide a criterion of ballast aggregate size distribution for paved track. The parameters considered in this study were different types of particle size distribution. Then the analysis for analyzing compressive and flexural strength, physical characteristics of aggregate, and the ballast box test were performed. In the test result of the physical characteristic performed by the ballast box test, the bearing capacity was measured lower than the expected value because of its boundary conditions. Among four types of ballast aggregate, type B was selected as one of best candidate distribution because of its bearing capacity, strength, development and economics.

The distribution and abundance of Antarctic krill (Euphausia superba), particularly in the South Atlantic, has traditionally been viewed as primarily determined by the flow of the Antarctic Circumpolar Current. Krill are viewed as being particles on a conveyor belt that carries them around the Antarctic continent resulting in a single circumpolar population. The evidence to support this viewpoint is largely circumstantial and there is very little direct evidence available of krill being moved by the currents-krill flux. There is also considerable biological and physical evidence which suggests that other factors may play a dominant role in the life history and distribution of krill. This review examines the evidence fur krill flux and also examines evidence that does not accord with this theory. The management implications of assuming krill flux are outlined and some lines for future research are suggested.

We derive a factorization theorem for the jet mass distribution with a given $p^J_T$ for the inclusive production, where $p^J_T$ is a large jet transverse momentum. Considering the small jet radius limit ($R{\ll}1$), we factorize the scattering cross section into a partonic cross section, the fragmentation function to a jet, and the jet mass distribution function. The decoupled jet mass distributions for quark and gluon jets are well-normalized and scale invariant, and they can be extracted from the ratio of two scattering cross sections such as $d{\sigma}/(dp^J_TdM^2_J)$ and $d{\sigma}/dp^J_T $. When $M_J{\sim}p^J_TR$, the perturbative series expansion for the jet mass distributions works well. As the jet mass becomes small, large logarithms of $M_J/(p^J_TR)$ appear, and they can be systematically resummed through a more refined factorization theorem for the jet mass distribution.

With the evolution of technology, cyber physical systems (CPSs) are being upgraded, and new types of cyber attacks are being discovered accordingly. There are many forms of cyber attack, and all cyber attacks are made to manipulate the target systems. A representative system among cyber physical systems is a cyber physical power system (CPPS), that is, a smart grid. Smart grid is a new type of power system that provides reliable, safe, and efficient energy transmission and distribution. In this paper, specific types of cyber attacks well known as false data injection attacks targeting state estimation and energy distribution of smart grid, and protection strategies for defense of these attacks and dynamic monitoring for detection are described.

Many important physical properties of natural or man-made aerosol particles such as light scattering, electrostatics charges, and toxicity, as well as their behavior involving physical processes like diffusion and thermophoresis depend strongly on their size distribution. Important aerosol behavior mechanisms affecting the size distribution of aerosol particles include condensation, deposition, and coagulation. (omitted)
