Nonlinear sliding surface design in variable structure systems for spacecraft attitude control problems is studied. A robustness analysis is performed for regular form of system, and calculation of actuator bandwidth is presented by reviewing sliding surface dynamics. To achieve non-singular attitude description and minimal parameterization, spacecraft attitude control problems are considered based on modified Rodrigues parameters(MRP). It is shown that the derived controller ensures the sliding motion in pre-determined region irrespective of unmodeled effects and disturbances.

The process of interpretation comprises the passage from blindness to pre-canonical responses, then the canonical interpretation and its dissemination. and finally silence and oblivion. But oblivion does not necessarily imply the conclusion of the interpretative process of work. A reinterpretation may follow. This study aims at searching the source of reinterpretation of Ronchamp Chapel. I analyzed the canonical interpretation. the site, function, and form of the chapel. I concluded that the contextualism, semiology, regionalism and other architectural conception may be the frame of reference for reinterpretation of Ronchamp Chapel.

Maxillary anterior crown fractures are a common form of injury that mainly affects children and adolescents. The position of maxillary incisors and their eruptive pattern carries a significant risk for trauma. In the pre-adhesive era, fractured teeth needed to be restored either with pin-retained inlays or cast restorations that sacrificed healthy tooth structure and were a challenge for dentists to match with adjacent teeth. But. recently the development of adhesive dentistry has allowed dentists to use the patient's own fragment to restore the fractured tooth. The purpose of this paper is to present 2 cases of reattachment of fractured teeth which had different fracture mode, and to evaluate prognosis of cases.

Objectives: The purpose of this study was to introduce the progress of treatment and improve clinical use after conducting Mentalizing the Rooms of Mind, the main technique of Mindfulness & Loving Beingness psychotherapy, for a patient with panic disorder. Methods: We conducted a Mentalizing the Rooms of Mind for 10 sessions on an age 23 female diagnosed with panic disorder based on the DSM-5 diagnostic criteria. After receiving consent from the subject, through chart review, the progress of treatment was observed focusing on the MMPI-2 and CSEI-s (The Core Seven Emotions Inventory-short form) conducted pre- and post-treatment. This study was approved by the Institutional Review Board of Wonkwang University Sanbon Hospital (WMCSB202007-55). Results: 1. The MMPI-2 clinical scales of an age 23 female with panic disorder showed a 7 (Pt)-1 (Hs)-3 (Hy) profile pre-treatment, but for post-treatment, the scale showed 1 (Hs)-3 (Hy) profile, and the 7 (Pt) scale showed significant decline. In the MMPI-2 reconstructed clinical scales, RC7 (Dysfunctional Negative Emotions) and RC8 (Aberrant Experiences) showed significant decline. 2. In the pre- and post-treatment MMPI-2 content scales, Anxiety, Fears, Obsessiveness, Social Discomfort, and Work Interference scores decreased, showing overall positive stability. On the MMPI-2 supplementary scales, the Anxiety and Post-Traumatic Stress Disorder scores decreased, and the Ego Strength increased, resulting in improved overall psychological adaptation. 3. Pre- and post-treatment of an age 23 female with panic disorder, CSEI-s showed significant decline of 恐, 驚, 悲, and 思. So it seems that the emotions caused by Chiljeongsang (七情傷) were more stable than before treatment. Conclusions: As shown above, the treatment of panic disorder through Mentalizing the Rooms of Mind, a major technique of Mindfulness & Loving Beingness psychotherapy, showed positive changes in MMPI-2 as well as improvement of the subjective symptoms. Thus, Mentalizing the Rooms of Mind has high clinical use, and it seems that it is necessary to create a manual for this in the future.

The practical learning requires the new paradigm in its content of education and environment along with the rapid development of information communication technology and the expansion of digital content industry. Especially, the animation education, core area of digital content industry, has attempted to improve the content and method of education by focusing on creativity, convergence and practical education. However, education environment in the previous form of computer laboratory has not been reflected the characteristics of animation education. In the light of this, this research would suggests the effective education environment implemented animation job competency and the characteristics of animation production. Firstly, the problem of previous educational environment will be explored through looking at computer rooms of domestic Universities. The characteristics of animation production consisted of Pre-production, Main-production, Post-production and elements of animation job competency will be reviewed by focusing on three phases of production, Pre-production, Main-production and Post-production, and six particular jobs, concept art, modeling & texturing, animating, lighting, VFX and compositing. Secondly, 6 types of space adapted from space syntax, possibly explored the embedded meaning of the structure of space and environment, will be reviewed by focusing on integration, separation and interaction. Thirdly, based on the characteristics of animation production, the element of animation job competency, 6 types of space, analytical tools about animation project education will be deducted, and the case study regarding animation studio, Walt Disney studio, will be processed by focusing on its production environment and spatial composition by focusing on Pre-production, Main-production, Post-production. Fifthly, the effective spatial composition for animation project education will be explored based on the interpretation of literature reviews and case study. In regard to this, the research addresses the spatial composition reflected the characteristics of practical learning and job competency in animation education, which differs from the previous form of standardized education spaces.

The functional properties of cheese, such as texture and melt, are known to be controlled by several important parameters. Recently, the characteristics of Ca in cheeses, especially the form of Ca (insoluble (INSOL) or soluble) and the shift in Ca equilibrium (i.e., from INSOL to soluble Ca), during aging has received a lot of attention. The INSOL form of Ca, which is present as a structural form in casein, plays a critical role in determining the functional properties of cheese during the early period of ripening (~1 mon). It seems that there is always a reduction of INSOL Ca content in cheese during ripening and there are also factors that can affect the shift in Ca equilibrium. These factors may include the composition of cheese milk, cheese manufacturing pH, acid development during aging, adopting curd-washing in various methods, pre-acidification of milk, etc. There have been many studies showing that the rheological and melting properties of cheese during ripening were significantly (p<0.05) affected by the shift in Ca equilibrium. Therefore, for cheese makers, it is now possible to predict/manage the functional properties of cheese by monitoring and controlling Ca equilibrium in cheese during aging.

The inverse kinematics problem of a reclaimer which excavates and transports raw materials in a raw yard is investigated. Because of the geometric feature of the equipment in which scooping buckets are attached around the rotating disk, kinematic redundancy occurs in determining joint variable. Link coordinates are introduced following the Denavit-Hartenbery representation. For a given excavation point the forward kinematics yields 3 equations, however the number of involved joint variables in the equations is four. It is shown that the rotating disk at the end of the boom provides an extra passive degree of freedom. Two approaches are investigated in obtaining inverse kinematics solutions. The first method pre-assigns the height of excavation point which can be determined through path planning. A closed form solution is obtained for the first approach. The second method exploits the orthogonality between the normal vector at the excavation point and the z axis of the end-effector coordinate system. The geometry near the reclaiming point has been approximated as a plane, and the plane equation has been obtained by the least square method considering 8 adjacent points near the point. A closed form solution is not found for the second approach, however a linear approximate solution is provided.
