MDO (Multidisciplinary Design Optimization) methodology is an emerging new technology to solve a complicate structural analysis and design problem with a large number of design variables and constraints. In this paper MDO methodology is adopted through the use of computer aided systems such as Geometric Solid Modeller, Mesh Generator, CAD system and CAE system. And this paper introduces MDO methodology as a new method for structural analysis and design through the application to the structural design of flap drive system. In a MDO methodology application to the structural design of flap drive system, kinetodynamic analysis is done using a simple aerodynamic analysis model for the air flow over the flap surface instead of difficult aerodynamic analysis. Simultaneously the structural static analysis is done to obtain the optimum structural condition. And the structural buckling analysis for push pull rod is also done to confirm the optimum structural condition (optimum cross section shape of push pull rod).

MDO (multidisciplinary design optimization) technology has been proposed and applied to solve large and complex optimization problems where multiple disciplinaries are involved. In this research. an MDO problem is defined for automobile design which has crashworthiness analyses. Crash model which are consisted of airbag, belt integrated seat (BIS), energy absorbing steering system .and safety belt is selected as a practical example for MDO application to vehicle system. Through disciplinary analysis, vehicle system is decomposed into structure subspace and occupant subspace, and coupling variables are identified. Before subspace optimization, values of coupling variables at given design point must be determined with system analysis. The system analysis in MDO is very important in that the coupling between disciplines can be temporary disconnected through the system analysis. As a result of system analysis, subspace optimizations are independently conducted. However, in vehicle crash, system analysis methods such as Newton method and fixed-point iteration can not be applied to one. Therefore, new system analysis algorithm is developed to apply to crashworthiness. It is conducted for system analysis to determine values of coupling variables. MDO algorithm which is applied to vehicle crash is MDOIS (Multidisciplinary Design Optimization Based on Independent Subspaces). Then, structure and occupant subspaces are independently optimized by using MDOIS.

The purpose of this study was to examine frequency of job performance, level of urgency, index of importance experienced by 138 new nurses who were working at 6 hospitals that had over 400 bed in Incheon and Bucheon. The data were analyzed using a SPSS program for descriptive statistics [numbers of job performance, level of urgency, index of importance(job performance+1/4 level of urgency)]. Some of the most frequent job performance were application of aseptic technique, application of principle of infection control, and medication (IV, PO, IM, supply fluid and electrolyte). Some of the most uncommon job performance were activity as a lecturer in nursing department, activity of arrangement of community resources, and participation in multidisciplinary conference. Some of the highest level of urgency were use of aseptic technique, CPR, application of principle of infection control, defibrillation for dysrhythmia, blood transfusion, observation of patient's status in procedure (operation), v/s check, intervention for improvement of respiratory function and medication of antihypertensives. Some of the lowest level of urgency were activity as a lecturer in nursing department, preceptor's activity, supervisor and delegation of job to nurse aids, attendance at nursing conference, activity of arrangement of community resources, participation in clinical teaching practice, participation in multidisciplinary conference, and delegation of patient care. Those were indirect patient care. The order was physiologic integration(60.99%), safety and effective nursing environment, psychosocial care, and health maintenance and improvement. The most importance item in maintenance of physiologic integration was medication. Some of the highest index of importance were aseptic technique and application of principle of infection control, v/s check, observation of patient's status in operation and medication. Some of the lowest index of importance were activity as a lecturer in nursing department, preceptor's activity, activity of arrangement of community resources, participation in multidisciplinary conference, nursing conference, participation in clinical teaching, and delegation of job to nurse aids.

As the significance of knowledge convergence continues to grow, universities are making efforts to develop methods that promote multidisciplinary learning. To address this educational challenge, our paper applies network theory and text mining techniques to analyze university curricula and introduces a graphical syllabus rendering method. Visualizing the course curriculum provides a macro and structured perspective for individuals seeking alternative educational pathways within the existing system. By visualizing the relationships among courses, students can explore different combinations of courses with comprehensive search support. To illustrate our approach, we conduct a detailed demonstration using the syllabus database of Yonsei University. Through the application of our methods, we create visual course networks that reveal the underlying structure of the university curriculum. Our results yield insights into the interconnectedness of courses across various academic majors at Yonsei University. We present both macro visualizations, covering 18 academic majors, and visualizations for a few selected majors. Our analysis using Yonsei University's database not only showcases the value of our methodology but also serves as a practical example of how our approach can facilitate multidisciplinary learning.

Transparent n-type metal-oxide semiconductor of $MoO_x$ was applied on a p-type Si substrate for high-performing heterojunction photodetector. The formation of $MoO_x$ on Si spontaneously established a rectifying current flow with a high rectification ratio of 1,252.3%. Under light illumination condition, n-type $MoO_x$/p-type Si heterojunction device provided significantly fast responses (rise time : 61.28 ms, fall time : 66.26 ms). This transparent metal-oxide layer ($MoO_x$) would provide a functional route for various photoelectric devices, including photodetectors and solar cells.

This paper presents an application of proportional-resonant (PR) current controllers in modular multilevel converter-high voltage direct current (MMC-HVDC) system under unbalanced voltage conditions. The ac currents are transformed and controlled in the stationary reference frame (${\alpha}{\beta}$-frame). Thus, the complex analysis of the positive and negative sequence components in the synchronous rotating reference frame (dq-frame) is not necessary. With this control method, the ac currents are kept balanced and the dc-link voltage is constant under the unbalanced voltage fault conditions. The simulation results based on a detailed PSCAD/EMTDC model confirm the effectiveness of the proposed control method.
