  • The purpose of this study was to research the opinion and acknowledgement about the clinical chronic disease care system subject to Medical Practitioners that copied the internal medicine and family medicine as a treatment subject and was fulfilled in the purpose of providing a basic data for the improvement and stable establishment of the chronic disease care system and the high blood pressure and diabetes mellitus patient's promotion of health. Results from the research the internal medicine was 79% and the subject's average age was 52.3 years, the proportion that the high blood pressure and the diabetes mellitus took was average 28% and the interest about the system was 65.9%. In the chronic disease care system expansion status the opposition was 75.7%, and the detail field knowledge level was 56.9%. In the opinion field about the system, all fields were shown negative. The chronic disease care system is an important government policy enforcing purposed to effectively manage the yearly increasing chronic disease, but the due to the cold attitude of Medical Practitioners that must actively accept it, the stable establishment of the system is being concerned. Therefore even if it's a good policy if it cant gain the support and agreement of the accepter, in the future when trying to implement a system there should be no idleness in the effort to gain cooperation and understanding to relevant involved ones.

  • IT project teams are composed of experts from various domains with different backgrounds, such as business and technologies. Thus, enhancing knowledge sharing and increasing team social capital are critical for the success of the project. This study examines the relationship among the team social capital, team climate and team performance. A research model and hypotheses are developed from literature review and empirically validated. The research model consists of team social capital, team climate and team performance. Specifically, team social capital, as antecedents, wasconceptualized asinternal and external differentiated by team boundary, and team climate is conceptualized as innovative climate and supportive climate. Using measures adopted from previous studies, 166 data points were collected to test the research model and related hypotheses. PLS data analysis indicated that internal and external social capitalhave positive effect on innovative climate while internal social capital has a positive effect on supportive team climate. The innovative and supportive climate has significant effect on the team performance. Based on the results, we proposed several team management skills for IT project managers. Theoretical constributions are discussed at the end with limitations and further studies.

  • It bas been hypothesized that foot ulceration might be internally initiated. Current instruments which merely allow superficial estimate of plantar loading acting on the foot, severely limit the scope of many biomechanical/clinical studies on this issue. Recent studies have suggested that peak plantar pressure may be only 65% specific for the development of ulceration. These limitations are at least partially due to surface pressures not being representative of the complex mechanical stress developed inside the subcutaneous plantar soft-tissue, which are potentially more relevant for tissue breakdown. This study established a three-dimensional and nonlinear finite element model of a human foot complex with comprehensive skeletal and soft-tissue components capable of predicting both the external and internal stresses and deformations of the foot. The model was validated by experimental data of subject-specific plantar foot pressure measures. The stress analysis indicated the internal stresses doses were site-dependent and the observation found a change between 1.5 to 4.5 times the external stresses on the foot plantar surface. The results yielded insights into the internal loading conditions of the plantar soft-tissue, which is important in enhancing our knowledge on the causes of foot ulceration and related stress-induced tissue breakdown in diabetic foot.

  • This paper proposes a method for the intelligent load distribution of two cooperating robots(TCRs) using fuzzy logic. The proposed scheme requires the knowledge of the robots' dynamics, which in turn depend upon the characteristics of large flat panel displays(LFPDs) carried by the TCRs. However, the dynamic properties of the LFPD are not known exactly, so that the dynamics of the robots, and hence the required Joint torque, must be calculated for nominal set of the LFPD characteristics. The force of the TCRs is an important factor in carrying the LFPD. It is divided into external force and internal force. In general, the effects of the internal force of the TCRs are not considered in performing the load distribution in terms of optimal time, but they are essential in optimal trajectory planning; if they are not taken into consideration, the optimal scheme is no longer fitting. To alleviate this deficiency, we present an algorithm for finding the internal-force (actors for the TCRs in terms of optimal time. The effectiveness of the proposed system is demonstrated by computer simulations using two three-joint planner robot manipulators.

  • In this research, an internal model based method is proposed to estimate the structural displacements and velocities under ambient excitation using only acceleration measurements. The structural response is assumed to be within the linear range. The excitation is assumed to be with zero mean and relatively broad bandwidth such that at least one of the fundamental modes of the structure is excited and dominates in the response. Using the structural modal parameters and partial knowledge of the bandwidth of the excitation, the internal models of the structure and the excitation can be respectively established, which can be used to form an autonomous state-space representation of the system. It is shown that structural displacements, velocities, and accelerations are the states of such a system, and it is fully observable when the measured output contains structural accelerations only. Reliable estimates of structural displacements and velocities are obtained using the standard Kalman filtering technique. The effectiveness and robustness of the proposed method has been demonstrated and evaluated via numerical simulations on an eight-story lumped mass model and experimental data of a three-story frame excited by the ground accelerations of actual earthquake records.

  • The internal core baffle structure of a French Pressurized Water Reactor (PWR) consists of a collection of baffles and formers that are attached to the barrel. The connections are done thanks to a large number of bolts (about 1500). After inspection, some of the bolts have been found cracked. This has been attributed to the Irradiation Assisted Stress Corrosion Cracking (IASCC). The $Electricit\acute{e}$ De France (EDF) has set up a research program to gain better knowledge of the temperature distribution, which may affect the bolts and the whole structure. The temperature distribution in the structure was calculated thanks to the thermal code SYRTHES that used a finite element approach. The heat transfer between the by-pass flow inside the cavities of the core baffle and the structure was accounted for thanks to a strong thermal coupling between the thermal code SYRTHES and the CFD code named Code_Saturne. The results for the CP0 plant design show that both the high temperature and strong temperature gradients could potentially induce mechanical stresses. The CPY design, where each bolt is individually cooled, had led to a reduction of temperatures inside the structures. A new parallel version of SYRTHES, for calculations on very large meshes and based on MPI, has been developed. A demonstration test on the complete structure that has led to about 1.1 billion linear tetraedra has been calculated on 2048 processors of the EDF Blue Gene computer.

  • We describe the case of a Jindo dog that presented with a 2-month history of an abscess-like mass on the skin of the left hip. The patient was initially diagnosed with a suspected insect bite and was treated with a topical dressing. After observing no improvements, surgical debridement was done to remove the abscess. Nine days after surgery, the patient started showing severe anorexia, vomiting, lethargy, and oliguria. Azotemia was detected, and the patient was diagnosed with acute kidney injury. Ultrasonography depicted an abdominal mass (4.6 × 7.5 cm) in the right ureter, and severe hydronephrosis in the right kidney. The patient was euthanatized. Results of the necropsy, histopathologic examination, and immunohistochemistry for tumor cells, confirmed that the patient had developed hydronephrosis and disseminated histiocytic sarcoma which had metastasized to the lungs. To the best of our knowledge, this is the first report of acute renal failure produced by ureter invasion and urinary tract obstruction resulting from the abdominal mass of disseminated histiocytic sarcoma in dogs.

  • Lung transplantation is widely accepted as the only viable treatment option for patients with end-stage lung disease. However, the imbalance between the number of suitable donor lungs available and the number of possible candidates often results in intensive care unit (ICU) admission for the latter. In the ICU setting, critical care is essential to keep these patients alive and to successfully bridge to lung transplantation. Proper management in the ICU is also one of the key factors supporting long-term success following transplantation. Critical care includes the provision of respiratory support such as mechanical ventilation (MV) and extracorporeal life support (ECLS). Accordingly, a working knowledge of the common critical care issues related to these unique patients and the early recognition and management of problems that arise before and after transplantation in the ICU setting are crucial for long-term success. In this review, we discuss the management and selection of candidates for lung transplantation as well as existing respiratory support strategies that involve MV and ECLS in the ICU setting.

  • Objectives: The purpose of this study is to investigate recent trends in randomized controlled trials (RCTs) on the treatment of Coronavirus disease 2019 (COVID-19) patients with traditional Chinese medicine (TCM) and analyze the results for the activation of COVID-19 Korean medicine research. Methods: We searched for RCTs published from December 2019 to October 2021 in the Chinese National Knowledge Infrastructure Database (CNKI). The investigation focused on the type of study, the purpose of the study, and the treatment methods. Results: A total of 8 RCTs were selected and analyzed from the 447 searched studies. All studies attempted to observe the effects of herbal medicine. Herbal medicine included granules, decoctions, and intravenous injections. The most frequently used herb type was drugs for clearing away heat and detoxification and releasing the exterior syndrome. In most studies, the effectiveness of TCM treatment of COVID-19 was significantly high. Conclusions: Although more quality studies are needed to support these results, TCM treatment for COVID-19 has been effective. Therefore, we hope that Korean medicine studies on infectious diseases will be actively conducted like TCM and contribute to national health.
