In this paper, we proposed the TDS(T-shape Diamond Search) based on the directions of above, below, left and right points to estimate the motion vector fast and more correctly in this method, we exploit the facts that most motion vectors are enclosed in a circular region with a radius of 2 fixels around search center(0,0). At first, the 4 points in the above, below, left and right around the search center is calculated to decide the point of the MBD(Minimum Block Distortion). And then w. above point of the MBD is checked to calculate the SAD. If the SAD of the above point is less than the previous MBD, this process is repeated. Otherwise, the right and left points of MBD are calculated to decide The points that have the MBD between right point and left point. Above processes are repeated to the predicted direction for motion estimation. Especially, if the motions of image are concentrated in the crossing directions, the points of other directions are omitted. As a result, we can estimate motion vectors fast. Experiments show that the speedup improvement of the proposed algorithm over Diamond Search algorithm(DS) and HEXgon Based Search(HEXBS) can be up to 38∼50% while maintaining similar image Quality.
The present study was investigated in the Chittagong hill forest of Bangladesh to assess the feasibility of ginger cultivation under multipurpose forest and fruit tree species. There were three treatments such as i) ginger grown under open field condition, ie. full sunlight (T1), ii) ginger grown under Gamar tree (spacing of $90{\times}90cm$ (T2) and iii) ginger grown under guava tree (spacing $180{\times}180cm$) tree (T3). The experiment was laid out in randomized block design (RBD) and each treatment was replicated three times. From data it was observed that some morphological parameters of ginger such as plant height, number of leaves per plant, leaf length and leaf breadth were higher in the treatments T2 and T3 as compared to the treatment T1. A positive and linear relationship was observed between the weight of rhizome and yield of ginger which caused the highest yield of ginger ($23.63Mg\;ha^{-1}$) under guava tree species at partial shaded condition in the T3 treatment ($180{\times}180cm$), whereas the lowest yield ($15.64Mg\;ha^{-1}$) was recorded in the T2 treatment when ginger was cultivated under Gamar tree species at closer spacing ($90{\times}90cm$). Therefore, it was revealed that partial shaded condition favoured the optimum growth and yield of ginger, whereas the dense shade from intensively planted tree species badly affected the dry matter production and yield of ginger.
This article deals with the short history from 1999 to the present time, how the Korean record and archives management world had grown up, and what the development of the branch of records and archives studies resulted in. First of all, it is looked out upon the transition and feature of each initiative bodies of records management, containing the records producing body, records and archives management body, records and archives professional body, and civil society. As a result, this article points out the disequilibrium state of the records producing body and civil society, for all the growth of records and archives management institutions and records and archives professionals. During the time of establishing the law, the Korean records and archives management had been made a rapid progress by some part of the leading group being to Korean Records and Archives Service and the society of professionals. But it is estimated only the malformed development depending on the model of elites, although we could achieve the establishment of Korean Records and Archives Act. The condition of records and archives management of the Participation Government was distinguish from the state of former times, being driven up the renovation of records and archives management. The main power of the renovation was sought our by overcome of the elite model with the development of archival institutions and professionals extending wide range. Particularly professionals to accept the education of graduate school grew up in quantity and quality and then they let the pattern of the collaboration with archival institutions rake root in Korea. As The Road Map on the Renovation of National Records and Archives Management was made, the government put into practice, so the management of records and archives in Korea could take a step of steady and continuous growth. But the development of the records producing bodies and civil society is staying at the low level as yet. Accordingly it is expected to have the most important means that the professional instruction become to normalize and archivists who posted in public agencies after graduating professional education program discharge their duties. And each public agencies have to speed up to set up the institutions for records management including some archivists so that overcome the condition of underdevelopment as fast as possible.

The purpose of this study was to examine the attitudes and satisfaction level towards military foodservices as well as suggest effective ways to increase foodservice quality. A questionnaire survey was administered to 413 subjects, which included 400 soldiers and 13 foodservice managers. The survey period was from August 6 to August 25, 2008. The collected data were statistically treated using SPSS V12.0. Most of the investigated soldiers were 20~25 years old. The foodservice managers were male general officials and the majority of them had no prior food service training. None of the foodservice managers had a dietician certificate. Menu was planned through a local foodservice conference, and most food materials were delivered in the form of center-type and military unit-type. Deficiency and deterioration of food service facilities (28.6%) as well as deficiency in the number of cooking personnel (14.3%) increased the difficulty of operational management. Soldiers expressed a desire for increases in Western (25.7%) and Korean traditional foods (21.5%), which meant menu diversity. To increase the quality of military foodservices, taste of food (40.6%), increased portion size (30.4%), and improvement in hygienic conditions (13.6%) were demanded by the soldiers. Food taste (30.8%), improvement in hygienic conditions (23.1%), and better job management were all demanded by the foodservice managers. After factor analysis, quality attributes were rearranged into five dimensions, including facilities, food, menu, service, and sanitation most attributes were over 4 points out of 5 total in importance, but only 3 points in performance. The importance score was higher than the performance score. Soldiers' overall satisfaction level was on average 3.43 points out of 5 points.
During more than 20 years of practice, Civil Aviation Law has experienced three times of amendments since it was enacted in 1995. But these revisions are limited to the technical level. The problems and limitations have become increasingly prominent in its implementation. Firstly, the civil aviation law is the result of interests game among several departments and some legal issues was left behind and the regulation was very vague as a result. Secondly, the process of aviation legislation is the process that the country has undergone profound changes and social transformation. The 20 years is long enough for the society to undergo tremendous changes and 1995 version of civil aviation law does not keep pace of development of economy. There was a serious lag between reality and the law. In order to actively promote the development of the aviation industry and overcome implementation issues of the Civil Aviation Law, Civil Aviation Administration of China (CAAC) initiated modification procedure the law and published new draft of Civil Aviation Law in August 2016. The spirit of this modification is to learn and absorb new achievements of domestic and foreign legislation and the International Convention on civil aviation. Furthermore, the purpose of the revision is to provide favorable policy for the development of civil aviation industry and improve aviation safety and supervision, strengthen and protection of consumer rights and interests, to enhance the safety of civil aviation activities, and promote the development of general aviation. This revision concerned to the 78 articles which are revised or deleted and 24 articles added. The highlights of the draft include but not limited to the enhancement of security management, clarification of the main responsibility for production safety. And also it added the provisions related to the construction of effective tracking capability of public air transport enterprises and license system on the transport of dangerous goods. Compared with the existing civil aviation law, the draft has made a great improvements. But there are several deficiencies and limitations in the drafts. These problems need to be supplemented and perfected through further amendments in near future.
In this paper, the problems in identifying the noise sources by using the sound intensity technique are dealt with for the general radiated near-field from vibro-acoustic sources. For this purpose, a three-dimensional model structure resembling the engine room of a car or heavy equipment is considered. Similar to the practical situations, the model contains many mutually coherent and incoherent noise sources distributed on the complicated surfaces. The sources are located on the narrow, connected, reflecting planes constructed with rigid boxes, of which a small clearance exists between the whole box structure and the reflecting bottom. The acoustic boundary element method is employed to calculate the acoustic intensity at the near-field surfaces and interior spaces. The effects of relative source phases, frequencies, and locations are investigated, from which the results are illustrated by the contour map, vector plot, and energy streamlines. It is clearly observed that the application of sound intensity technique to the reactive or reverberant field, e.g., scanning over the upper engine room as is usually practiced, can yield the detection of fake sources. For the precise result for such a field, the field reactivity should be checked a priori and the proper effort should be directed to reduce or improve the reactivity of sound field.

When a radial wheel is placed so as to partially overlap a conductive plate and rotated, a lift force is generated on the wheel, a thrust force along the edge, and a lateral force which tends to reduce the overlap region. When several of these wheels are combined, it is possible to realize a system in which the stability of the remaining axes is ensured, except in the traveling direction. To validate the overall characteristics of the multi-wheel system, we propose a transfer system levitated magnetically using radial electrodynamic wheels. The proposed system is floated and propelled by four wheels and arranged in a structure that allows the thrusts generated by the front and rear wheels to offset each other. The dynamic stability of the wheel and the effect of the pole number on the three-axial forces are analyzed by the finite element method. At this time, the thrust and levitation force are strongly coupled, and the only factor affecting them is the wheel rotation speed. Therefore, in order to control these two forces independently, we make use of the fact that the ratio of the thrust to the levitation force is proportional to the velocity and is independent of the size of the gap. The in-plane and out-of-plane motion control of the system is achieved by this control method and compared with the simulation results. The experimental results show that the coupled degrees of freedom can be effectively controlled by the wheel speed alone.
This study aims at examining how it becomes to change the interpersonal cognitive problem solving ability development of elementary rejected children when teacher practices counseling strategy in classroom To do this, 130 fifth-graders of 4 classrooms from H Elementary School in B City went through Ahn Ie-hwan's(2007) social status type system by using the peer nomination, Then, 21 children were labeled as rejected children. Among them, 16 children were divided into experimental group & control group, 8 for the each group. In order to improve the interpersonal cognitive problem solving ability of rejected children with teacher's counseling strategy in classroom used in this study, 5 weeks activity made according to the level of classroom was carried out in four sides, that is, setting of classroom structure-environments, classroom activities, counseling activities, cooperative learning method, referring to Dreikurs'(1971) 'The counseling strategy in classroom' composed of self-discipline, cooperation, mutual respect, shared responsibility, and social equality. This study obtained the following results. First, There was a significant effect in improving the interpersonal cognitive problem solving ability of rejected children. Looking into sub-factors, there was a significant effect in improving consequential thought and method-ends thought except alternative solution thought and causal thought. Second, there was a significant difference in social status & change of 5 types of children in social status in the respective classrooms when those of the experimental group where teacher's counseling strategy in classroom carried out and those of the control group where teacher's counseling strategy in classroom not carried out were compared. To conclude the results mentioned above, We can see the fact that the counseling strategy in classroom positively affected interpersonal cognitive problem solving ability.
The purpose of this study was to improve work performance conducted at an actual clinical site by determining the relationship among critical thinking disposition, problem solving ability, and work performance. In this study, 335 dental hygienists completed self-administered survey. Final analysis was conducted with a total of 331 responses, excluding 4 questionnaire with unreliable responses and non-responses. The results indicated that as the age, educational background, and work experience of the subjects increased, their critical thinking disposition and problem solving ability scores increased and were statistically significant. For work performance, average total score was high for age, educational background and work experience, but only age and work experience were statistically significant. Critical thinking disposition, problem solving ability and work performance of the subject were relevant, and all of them were significant. Work performance was also influenced indirectly by mediating problem solving ability in critical thinking disposition. In other words, both direct and indirect effects were significant, and the existence of partial moderating effect was verified. Thus, in order to improve work performance of dental hygienists, a multilevel educational process that can simultaneously improve critical thinking disposition and problem solving ability of dental hygienists needs to be developed. Therefore, it is expected that the new dental hygiene company will be able to perform without any sense of disparity in the clinical field; this will solve the gap between dental hygiene education and practical skills.
The light is the language. Directors have to describe the scene component effectively his intention to configure the scene as an appropriately. After this act of the character, the layout of the props and scene lights will enter to the scene components. Those things help to audiences can understand narrative of work and emotion that producer want to send. Expressing their emotions especially using the lights by adjusting the colors and contrast makes audience to concentrate on work and understand naturally. This lighting technique clearly appears on early year theaters stage of England and Rembrandt's paintings. Properly dividing and controlling the lights dramatically increases the beauty of the work elements to express a variety of emotions such as worries and fear. Therefore, it can be evolve depending on director's intent of using lights on his work. Lights can increase involvement of human emotion through basic features that cognition of object, visualization of space-time and by artistic method in the product. This study will examine the role and how to use lighting to express the proper sentiment based on the narrative of the work. Making research named "Lighting Research of 3D animated film which applying light features to express emotion" previous study and have to combine emotional vocabulary and emotion-based theory for classifying the emotional language that can be applied on 3D animation. And choosing most emotional scene from 3D animation for analyze how they used lighting to expressing emotions. Directors trying to show up about the light role through light method that matched perfectly with an emotional language. Expecting this research work of directing 3D animations light for expressing emotional feelings will be continue successfully.
