The purpose of this paper is to show how psychopaths' psychological factors are expressed on the characters' visual styles in the make-up coordination of slasher films. Psychopath is an ordinary person who has suffered some terrible trauma (humiliation, the death of a loved one, rape, psychological abuse), and features a disorder that consists of multiple components ranging on the emotional, interpersonal, and behavioral spectrum. Slasher films are sub genre of horror films that psychopathy characters, namely, Leather Face, Michael Myers, Jason Voorhees, Kenny Hampson, Harry Warden, Freddy Kruger and Billy kill the unfamiliar victims by cruel weapons with mercilessly. Their aesthetic characteristics of make-up coordination were shown in concealment, cruelty and suggestion. The concealment was presented by killers' masks, the cruelty was represented by their weapons, and the suggestion, especially space-time and status was depicted by their garments.

Unlike actual vehicles, a vehicle driving simulator is limited in kinematic workspace and bounded on dynamic characteristics. So it is difficult to simulate dynamic motions of a multi-body vehicle model. In order to overcome these problems, a washout algorithm which controls the workspace of the simulator within the kinematic limitation is needed. However, a classical washout algorithm contains several problems such as generation of wrong sensation of motions by filters in tilt coordination, requirement of trial and error method in selecting the proper cut-off frequencies, difficulty in returning the simulator to its origin using only high pass filters and etc. This paper proposes a new tilt coordination method as an algorithm which gives more accurate sensations to drivers. In order to reduce time for returning the simulator to its origin, a new washout algorithm that the proposed algorithm selectively onset mode from high pass filters and return mode from error functions is proposed. As a result of this study, the results of the proposed algorithm are compared with the results of classical washout algorithm through the human perception models. Also, the performance of the suggested algorithm is evaluated by using human perception and sensibility of some drivers through experiments.

Ab initio calculations of the structure, atomic charges and natural bond orbital (NBO) have been performed at HF/6-311G** and B3LYP/6-311G** levels for the title compound of dibenzothiazyl-disulfide. The calculated results show that the two nitrogen atoms have the biggest negative charges and they are the potential sites to react with the metallic ions, which make the title compound become a di-dentate ligand. Vibrational frequencies of the title compound have been obtained and compared with the experimental value and the comparison indicates that B3LYP/6-311G** level is better than HF/6-311G** level to predict the vibrational frequencies for the system studied here. For the title compound, electronic absorption spectra calculated by time?ependent density functional theory (TD-DFT) are more accurate than Hartree-Focksingle-excitation CI (CI-Singles) method. NBO analyses show that the electronic transitions are mainly derived from the contribution of bands $\pi\rightarrow\pi^{*}$. Thermodynamic calculated results show that the formation of the title compound from 2-mercaptobenzothiazole is a spontaneous process at room temperature with the change of free Gibbs being negative value.

The Dynamic Vehicle Routing Problem (DVRP) involves a combinatorial optimization problem where new customer demands become known over time, and old routes must be reconfigured to generate new routes while executing the current solution. We consider the high level of dynamism problem. An application of highly dynamic DVRP is the ambulance service where a patient contacts the service center, followed by an evaluation of case severity, and a visit by a practitioner/ ambulance is scheduled accordingly. This paper considers a variant of the DVRP and proposes a decentralized algorithm in which collaborators (Depot and Vehicle), both have only partial information about the entire system. The DVRP is modeled as a periodic re optimization of VRP using the proposed decentralized algorithm where collaborators exchange local information to achieve the best global objective for the current state of the system. We assume the existence of a dispatcher e.g., headquarter of the company who can communicate to vehicles in order to gather information and assigns the new visits to them. The effectiveness of the proposed decentralized coordination algorithm is further evaluated using benchmark data given in literature. The results show that the proposed method performed better than the compared algorithms which utilize the centralized coordination in 12 out of 21 benchmark problems.

A vehicle driving simulator is a virtual reality device which makes a man feel as if he drove an actual vehicle. Unlike actual vehicles, the simulator has limited kinematical workspace and bounded dynamic characteristics. So it is difficult to simulate dynamic motions of a multi-body vehicle model. In order to overcome these problems, a washout algorithm which controls the workspace of the simulator within the kinematical limitation is needed. However, a classical washout algorithm contains several problems such as generation of wrong sensation of motions by filters in tilt coordination, requirement of trial and error method in selecting the proper cut-off frequencies and difficulty in returning the simulator to its origin using only high pass filters. This paper proposes a washout algorithm with new tilt coordination method which gives more accurate sensations to drivers. To reduce the time in returning the simulator to its origin, an algorithm that applies selectively onset mode from high pass filters and return mode from error functions is proposed. As a result of this study, the results of the proposed algorithm are compared with the results of classical washout algorithm through the human perception models. Also, the performance of the suggested algorithm is evaluated by using human perception and sensibility of some drivers through experiments.

This paper proposes a method for constructing the virtual characters adopting the personal body types for the clothing coordination. At first, the method produces the 38 kinds of the Korean 3D body models considering sex, ages and body types, and constructs model DB. We select a model similar to the personal body size from DB and deform the selected model according to body size. The method deforms the model linearly for height 12 items, width 6 items, depth 5 items and round 13 items, and constructs the personal character fitted to the personal body size. The preprocess for model deformation consists of grouping for body part and establishing the feature points. Linear deformation for each group leads us to easy construction of the virtual personal characters. This method has two advantages as follows: 1. Large reduction of man power, cost and time for DB construction of the body 3D models, since the preprocess permits us to effectively use the various body models whose geometrical structures are different, 2 Suitability to Web-based clothing coordination, since the body deformation method is simple and its speed is very high.

Node localization is the basic task of underwater wireless sensor networks (UWSNs). Most of the existing underwater localization methods rely on ranging accuracy. Due to the special environment conditions in the ocean, beacon nodes are difficult to deploy accurately. The narrow bandwidth and high delay of the underwater acoustic communication channel lead to large errors. In order to reduce the ranging error and improve the positioning accuracy, we propose a localization algorithm based on ranging correction and inertial coordination. The algorithm can be divided into two parts, Range Correction based Localization algorithm (RCL) and Inertial Coordination based Localization algorithm (ICL). RCL uses the geometric relationship between the node positions to correct the ranging error and obtain the exact node position. However, when the unknown node deviates from the deployment area with the movement of the water flow, it cannot communicate with enough beacon nodes in a certain period of time. In this case, the node uses ICL algorithm to combine position data with motion information of neighbor nodes to update its position. The simulation results show that the proposed algorithm greatly improves the positioning accuracy of unknown nodes compared with the existing localization methods.

At the present time, interest in hydrogen is increasingly growing worldwide to tackle climate change. Korea also takes an action by announcing the first hydrogen economy implementation basic plan with the import targets of 22.9 million tons of hydrogen from oversea in 2050. To achieve this plan, it is very essential to establish an overseas hydrogen supply chain. In this paper, the study estimates the import price for hydrogen into basic scenario and comprehensive scenario, and also analyses economic feasibility considering price of the each technology.

The purpose of this study was to make clear considerations in the planning of community housing and the roles of coordinators. Seongmisan village, a representative urban community village in Seoul, was selected for this study on problem solving between residents and opinion coordination between residents and coordinators. For this qualitative research, 2 residents and 2 coordinators answered 'open questionnaires' on prior basic planning, land purchase, financing, architectural planning, construction and inspection, and actual living conditions thereafter. They were each interviewed for 2 hours at a time that was 14-16 months after the residents started living in the new houses, and the records were transcribed. The following was the result. 1) The residents, who ruled the steps of prior basic planning and land purchase, did not have sufficient information or knowledge of the construction of community housing, so that they faced difficulties especially in the legal and financial aspects. 2) The coordinators participated in the project at the steps of architectural planning and construction. The residents accepted the coordinators' opinions on the choice of floor and position, and the coordinators listened to the residents' opinions on individual plans and finishing materials. In the construction step, however, there was conflict between them, and dissatisfaction occurred on the completion time and construction cost. For the successful construction of community housing, a professional coordination company needs to join the project to establish a system of opinion coordinating from the step of prior basic planning to the step of afterconstruction management.

The goal of this study was to investigate the lower extremity's coordination determined by temporal relations with increasing high-heel (3, 7, 9cm) while walking on a treadmill. Twelve healthy women who walked on a treadmill under three conditionswearing 3cm high-heel shoes, 7cm, and 9cm-while kinematic data were collected using a six-cameras (240Hz) Qualisys ProReflex System. From these data, knee flexion, tibia internal rotation, and foot eversion were calculated in Euler technique and found the time for occurring the maximum angle of these movements. The maximum angle of these movements occurred almost simultaneously in 3cm high-heel walking, but not in 7cm and 9cm. The ratio of time for maximum angle of the foot eversion to tibia internal rotation converged to 1 in 3cm high-heel walking, but were less than 1 in 7cm and 9cm. In conclusion, it was indicated that 3cm high-heel walking had better the lower extremity's coordination compared with 7, 9cm high-heel walking.
