  • Multidisciplinary design optimization(MDO) can yield optimal design considering all the disciplinary requirements concurrently. A method to implement the collaborative optimization(CO) approach, one of the MDO methodologies, is developed using a pre-compiler “EzpreCompiler”, a design optimization library “EzOptimizer”, and a common object request broker architecture(CORBA) in distributed computing environment. The CO approach is applied to a mathematical example to show its applicability and equivalence to standard optimization(SO) formulation. In a realistic engineering problem such as optimal design of a two-member hub frame, optimal design of a speed reducer and initial design of a bulk carrier, the CO yields better results than the SO. Furthermore, the CO allows the distributed processing using the CORBA, which leads to reduction of overall computation time.

  • Purpose: The purpose of this study is to evaluate treatment results of multidisciplinary approach of critical ischemic limb with diabetic foot. Materials and Methods: From March 2005 to March 2012, 674 diabetic foot patients were analyzed. Among them, 85 patients were neuroarthropathic type, 383 patients were infectious type, and 206 patients were ischemic type. The subjects were 206 patients who had critical ischemic limbs and major or minor amputations were done. Various single or combined treatment method before amputation was performed. We investigated their ABI, HbA1c, main occlusion lesion, limb salvage and hospitalization period by various treatment method. Results: Major amputation was 27 cases, minor amputation was 179 cases. Mean HbA1c was 8.2%, and mean ABI was 0.66. Main occlusion lesion was 6 cases at common iliac artery, 13 cases at external iliac artery, 9 cases at internal iliac artery, 11 cases at common femoral artery, 23 cases at deep femoral artery, 52 cases at superficial femoral artery, 35 cases at popliteal artery, 40 cases at posterior tibia artery, 35 cases at anterior tibial artery, 28 cases at peroneal artery, and 13 cases at dorsalis pedis artery. Major amputations were decreased, minor amputations were increased, and hospitalization period was reduced by treatment of multidisciplinary approach. Conclusion: Treatment of multidisciplinary approach, which include preoperation percutaneus transluminal angioplasty, vascular surgery, and amputation, of critical ischemic limb with diabetic foot had advantages of limb salvage and hospitalization period reduction.

  • Existing methods have performed the reliability analysis using nonlinear optimization techniques. This is mainly due to the fact that they directly apply Multidisciplinary Design Optimization(MDO) frameworks to the reliability analysis formulation. Accordingly, the reliability analysis and the Multidisciplinary Analysis(MDA) are tightly coupled in a single optimizer, which hampers utilizing the recursive and function-approximation based reliability analysis methods such as the Advanced First Order Reliability Method(AFORM). In order to utilize the efficient reliability analysis method under multidisciplinary analysis systems, we propose a new strategy named Sequential Approach on Reliability Analysis under Multidisciplinary analysis systems(SARAM). In this approach, the reliability analysis and the MDA are decomposed and arranged in a sequential manner, making a recursive loop. The efficiency of the SARAM method was verified using three illustrative examples taken from the literatures. Compared with existing methods, it showed the least number of subsystem analyses over other methods while maintaining accuracy.

  • Aim: The purpose of this paper is to present the importance of multidisciplinary strategies in cancer prevention and control, especially comprehensive breast cancer care. Background: Worldwide, breast cancer is the most common cancer diagnosed among women and is the leading cause of cancer deaths. Although the incidence of breast cancer in Asian countries is still lower than in Western countries, the rate of increase for the last two decades is striking. Methods: Data on cancer mortality, incidence, and risk factors were summarized by using the most recent data available from population-based cancer registries affiliated with the International Union Against Cancer, the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program and the CDC's National Program of Cancer Registries (NPCR). Results: Global differences in breast cancer incidence and fluctuations in rates within a country still exist. The incidence of breast cancer in Asian countries was lower than in Western countries. Breast cancer incidence in the United States decreased each year during 1999-2003. On the other hand, morbidity and mortality related to breast cancer in Asia has increased significantly. Conclusion: Multidisciplinary strategies to reduce breast cancer mortality and promote breast cancer awareness are addressed. Lessons learned from multidisciplinary approaches to cancer treatment and control will be valuable in implementing future breast cancer research in the fields of basic, clinical, and population research in Asia.

  • A new approach, Multi-Objective Design Exploration (MODE), is presented to address Multidisciplinary Design Optimization (MDO) problems by CFD-CSD coupling. MODE reveals the structure of the design space from the trade-off information and visualizes it as a panorama for Decision Maker. The present form of MODE consists of Kriging Model, Adaptive Range Multi Objective Genetic Algorithms, Analysis of Variance and Self-Organizing Map. The main emphasis of this approach is visual data mining. An MDO system using high fidelity simulation codes, Navier-Stokes solver and NASTRAN, has been developed and applied to a regional-jet wing design. Because the optimization system becomes very computationally expensive, only brief exploration of the design space has been performed. However, data mining result demonstrates that design knowledge can produce a good design even from the brief design exploration.

  • 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.

  • This study was designed to develop the life moking cessation program with multidisciplinary approach using the Bandura's theory of self-efficacy and confirm the effect of it on the self-efficacy and smoking amount in college students. For this purpose non-equivalent control group, pretest-posttest design was used. The participating subjects in this study were 46 male college freshmen, 23 in experimental and 23 in control group. The experimental group received the 8 sessions of lecture and small group discussions for 4 weeks and a telephone coaching program for a period of 8 weeks. The control group received 5 sessions of lecture without further treatments. The data was collected from March 15 to June 11, 1999, and analysed by SAS/PC program with $\chi$$^2$test, simple t, paired t test. The results were as follows. 1. The score of self-efficacy was significantly increased over time in the experimental group than those of the control group. 2. The amount of urine cotinine was decreased over time in the experimental group, number of cigarettes smoked a day were significantly decreased, and they were significantly less than those of the control group. In conclusion it was found that the Life Smoking Cessation Program with Multidisciplinary Approach was an effective nursing intervention for increasing self efficacy and reducing the amount of smoking in male college students. Therefore, future smoking cessation programs should always consider the concept of self-efficacy and ways to positively reinforce it.
