  • Recent the advanced technologies in medical imaging such as magnetic resonance imaging (MRI) and computed tomography (CT) make doctors improve the diagnostic skill with detailed anatomical information. In general, it is necessary to get a number of MRI images in order to obtain more detail information. However, the performance of MRI machines of privately run hospitals is not good and thus we may obtain only a few of MRI images. If 3D surface reconstruction is accomplished with a few slices, then it generates 3D surface of poor qualify. This paper propose a way to Set a 3D surface of high quality from a few of number of slices. First of all, our algorithm detects the boundary of tissues which we want to reconstruct as a 3D object and find out the set of vortices on the boundary. And then we generate a 3D implicit surface to interpolate the boundary points by using radial basis function. Lastly, we render the 3D implicit surface by using Marching cube algorithms.

  • A large number of MJO skill metrics and process-oriented MJO simulation metrics have been developed by previous studies including the MJO Working Group and Task Force. To assess models' successes and shortcomings in the MJO simulation, a standardized set of diagnostics with the additional set of dynamics-oriented diagnostics are applied. The Global Coupled (GC) model developed for the operation of the climate prediction system is used with the comparison between the GC2 and GC3.1. Two GC models successfully capture three-dimensional dynamic and thermodynamic structure as well as coherent eastward propagation from the reference regions of the Indian Ocean and the western Pacific. The low-level moisture convergence (LLMC) ahead of the MJO deep convection, the low-level westerly and easterly associated with the coupled Rossby-Kelvin wave and the upper-level divergence are simulated successfully. The GC3.1 model simulates a better three-dimensional structure of MJO and thus reproduces more realistic eastward propagation. In GC2, the MJO convection following the LLMC near and east of the Maritime Continent is much weaker than observation and has an asymmetric distribution of both low and upper-level circulation anomalies. The common shortcomings of GC2 and GC3.1 are revealed in the shorter MJO periods and relatively weak LLMC as well as convective activity over the western Indian Ocean.

  • Water problems recently, not only influence environmental issues such as water quality and water management but also influence socioeconomic issues such as poverty, gender, and regional conflicts. Therefore there is increasing attention on water education as part of the environmental education. Yet water education in formal education is only treated with particular subjects like science and social studies with limited contents which fails to cover the social, economic problems related to water thoroughly. Also, though there is an active water education on the field of informal education. its contents are also very limited. Water education requires the implementation of a comprehensive and holistic approach that can holistically consider economic and social problems as well as environmental problems. Therefore in this research, 'water education for sustainable development' is set up as a direction of contents development which include interdisciplinary and holistic aspects. Contents development of water education for sustainable development is an reflection of the experts and teacher's opinions and contain of: main category dividing into three pillars of sustainable development such as environment, economy, and society, and subcategory covering environmental science's objective including knowledge, skill, attitude, and action as well as local, national, regional, and global issues.

  • This study clarified the fact that the existing 'manpower supply and demand plans', preceding studies, theoretical researches of the past cannot satisfy the multi-goals of organizations, instead, the existing plans focused on only the number of customers and total amount of service. Next, a necessity of more proper manpower plans that consider comprehensive goals of the organizations is suggested then, this study tried to make the countermeasures. As for studying methods, a priority sequence in the organizations' manpower management's goals is set by AHP(Analytic Hierarchy Process), a business administrative scientific skill. Proper manpower policies of the food service enterprises, which satisfy the organizations' multi-goals, are established by GP(Goal Programming). Based on it, mid and short term 'manpower supply and demand plans' are established. For the purpose of increasing the study's efficiency, example studies are conducted in one family restaurant. The limit of this study is that inner personnel management details such as promotion, new personnel appointments, unemployment, retirement were not considerately considered. Therefore, the future studies should think over those limits and research the labor-force supply from the outside also.

  • Audiometric calibration is a prerequisite for securing the reliability of audiometric test results by checking the internal consistency of the relevant instrument. The purpose of this review is to help instrument operators understand the calibration procedure of aural acoustic immittance instrument which is frequently used for objective assessment. By referring to the latest international standards and the national standards relevant to the aural acoustic immittance instrument, the following parameters will be reviewed: 1) introduction of performance characteristics, 2) detailed procedure of the calibration method. According to the newest international and national standards [IEC 60645-5 (2004), ANSI S3.39-1987 (R2012)], the aural acoustic immittance instrument basically includes six components: 1) calibration cavity, 2) acoustic immittance analysis system, 3) probe assembly/unit and signal, 4) pneumatic air-pressure pump system, 5) acoustic reflex activator system and 6) tympanogram and acoustic reflex plotting system, each of these components should meet set standards. The result of behavioral hearing tests is influenced by various complex factors including the examinee's cooperation, background noise of the examination room, measurement method, skill level of the audiologist and calibration status, but the objective hearing tests is more influenced by the calibration status of the instrument than any other factors. The audiologist should take full responsibility for the reliability of the hearing test result, so he/she should carry out the calibration check and adjustments of aural acoustic immittance instrument periodically and maintain the instrument continuously by referring to the newest standards and the manufacturer's instruction manual.
