Recently, the development of image processing technology, as well as hardware performance, has been continuing the research on 3D point processing technology that provides users with free viewing angle and stereoscopic effect in various fields. Point cloud technology, which is a type of representation of 3D point, has attracted attention in various fields because it can acquired/expressed point precisely. However, since Hundreds of thousands, millions of point are required to represent one 3D point cloud content, there is a disadvantage that a larger amount of storage space is required than a conventional 2D content. For this reason, the MPEG (Moving Picture Experts Group), an international standardization organization, is continuing to research how to efficiently compress, store, and transmit 3D point cloud content to users. In this paper, a V-PCC bitstream generated by a V-PCC (Video-based Point Cloud Compression) encoder proposed by the MPEG-I (Immersive) group is composed of an MPU (Media Processing Unit) defined by the MMT. In addition, by extending the signaling message defined in the MMT standard, a parameter for a segmented transmission method of the 3D point cloud content by area and quality parameters considering the characteristic of the 3D point cloud content, so that the quality parameters can be selectively determined according to the user's request. Finally, in this paper, we verify the result through design/implementation of the verification platform based on the proposed technology.

We reported two cases of amantadine treatment in traumatic brain injury patients and reviewed the literature of amantadine treatment of those patients. Problems with short-term memory, attention, planning, problem solving, impulsivity, disinhibition, poor motivation, and other behavioral and cognitive deficit could occur following traumatic brain injury or other types of acquired brain injury. This report described results of amantadine using in two patients with this type of symptom profile. Patients received neuropsychiatric examination as well as BPRS and Barthel index. These patients were improved, respectively from 57 point to 82 point(case 1), from 85 to 94(case 2) in Barthel index, and from 66 point to 35 point(case 1), from 55 to 32 point(case 2) in BPRS. These two patients did not reveal any other adverse effect. The rationale for using amantadine were discussed.

The effect of thermal stress on a ship's hull is not considered to be serious by most naval architects. Frequently, however, cracking of hulls has been reported which occurred at sea while there were no external forces except the heat from the sun. Detailed investigations have been made of these reports and it has been reliably determined that the damage was initiated by solar heating. The author is not interested in all steel ship or in the applicability and validity of the formular itself, as it has already been proven by the experiments such as S.S. Boulder Victory. The author therefore proceeds directly to calculate the stress distribution on he hull and superstructure of the prototype model ship. These calculations are based on the experimental nonsymetrical temperature gradient data taken earlier on the Boulder Victory. The calculations were made principally to determine the extent of stresses which occurred on an all-steel ship in one case and secondly, those that occurred on a ship with a steel hull and an aluminum superstructure. From the calculations, the author expected the stress distribution of the two case would show distinctly different aspects, but the acquired results were very similar. Generally, at the point of junction of the steel hull and aluminum superstructure sharp peak stresses appeared. At the juncture of the superstructure and the main deck the ship with the aluminum superstructure registered almost 1000 psi more stress than did the ship with the all-steel construction. In the view of these findings, the author recommends to ship designers that pay particular attention to the point of junction of steel and aluminum plate. The author has proven that it is extremely important that a greater safety factor be used at the aluminum-steel junction point than at any other point. Although thermal effects cause high juncture-point stresses in all-steel ships, they are not nearly as critical as in ship constructed of two or more metals.

The purpose of this study is to identify the effect of four clothing cues(hue, tone, skirt width, and skirt length of dress) on female impressions. The experimental materials developed for this study are a set of stimuli and response scales. The Stimuli are 40 color pictures manipulated with four clothing cues by drawing. The 7-point scale designed for visual evaluation of female impression formation includes 29 bipolar adjectives. The subjects were 240 undergraduate female students in Jinju city. The results of this study are as follow: As analyzing the impression of the female figure by the hue, tone, skirt width, and length, five factors including ability activity, elegance, attractiveness, concentration of attention, and tenderness were identified. Among these factors, ability activity and elegance were proved to be more important. Each impression of hue and tone with skirt width length have significant effects on concentration of attention, and tenderness. We can express various impressions by diversifying hue and tone. Each impression of skirt width length with hue and tone have significant effects on ability activity and elegance.

The purpose of this study is to investigate the effect of hair-style (straight and wave), hair-length(short, medium, and long), and type of hat design (no-hat, beret, cloche, bowler, and capeline) on impression formation. The experimental materials developed for this study were a set of stimulus and response scales. The 7-point semantic differential response scales were designed. Thirty stimuli color pictures of various combination of hair length, hair style, and type of hat design were manipulated by computer drawing. The subjects were 360 undergraduates living in Seoul, Kyunggi and Kyungnam. The experimental design was composed of 3 factorial designs. The result of the study can be summarized as follows; Impression factor of the stimulus consisted of the 5 different dimensions (attractiveness, gracefulness, activity, concentration of attention, cuteness). Hair style greatly affected gracefulness. On the other hand, hair length made remarkable effects on attractiveness, concentration of attention, and cuteness. In addition, it has been found that the type of hat design significantly influenced on all the factors except attractiveness as independent variables. In regarding the effect of interaction between each variable, the combination of hair style and hair length had significant effects on gracefulness. In the impression formation of cuteness, the combination of hair length and type of hat design were more significant.

The rapid progress of the intermodal freight transportation in recent years has induced fierce competition among the adjacent hub ports for container transport. This brings increased attention to the evaluation of the port competitive ability. But it is not easy to evaluate the port competitive ability because this belongs to ill-defined system which is composed of ambiguous interacting attributes. Paying attention to this point, this paper deals the competitive ability of container port in Far-East Asia by fuzzy integral evaluation which is adequate to interacting ambiguous attribute problem. For this, the proposed fuzzy evaluation algorithm is applied to the real problem, based on the factors such as cargo volumes, costs, services, infrastructure and geographical sites These are extracted from the precedent study of port competitive ability, etc. The results show that the port evaluation factors come in following order ; services, costs, infrastructure, geographical sites and cargo volumes. There are some interactions(interaction coefficient, ${\lambda}=-0.664$ between evaluation attributes. The port competitive ability comes in following order : Singapore, Hongkong, Kobe, Kaoshiung and Busan. According to the sensitivity analysis, the rank between Busan and Kaoshiung changes when ${\lambda}=0.7$. From the analysis of the results, we confirmed that the proposed fuzzy evaluation algorithm is very effective in the complex-fuzzy problem which is composed of hierarchical structure with interacting attributes.

The study investigates some psychological and environmental factors affecting the intention to purchase organic foods of consumers in the inner-city of Hanoi. Impact factors applied for the study include three psychological factors (health concern, environmental concern, consumer awareness of organic foods) and seven environment factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, social status, mass media, state's encouragement). We analyzed research data from 396 consumers to measure the impacting level of these factors. The convenient sampling method was used to collect the research sample. The measurement applied a 5-point Likert scale classifying from 1-completely disagree to 5-completely agree. Based on previous studies, the research model was recommended. We had estimated the reliability of the scales through Cronbach's Alpha and composite reliability. The research data is analyzed by using Structural Equation Model method (SEM). The findings of the study suggest that psychological factors (health concern, environmental concern, consumer awareness of organic foods) had a significantly positive influence on consumer's purchase attention toward organic food. The results also revealed that environmental factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, mass media) were positively linked to consumer's purchase attention toward organic food.
