A novel quantum chemical molecular dynamics program, 'Colors' was developed to simulate the electronic structure of rare earth-doped phosphor materials as well as the destruction processes of MgO protecting layer in plasma display panel (PDP). We have also developed a quantitative prediction method based on Monte Carlo simulation technique to evaluate the electrical conductivity of insulators, semiconductors, and metals as well as the spatial distribution of electron density by Colors code. All these original simulators enable us to study theoretically a variety of materials related to PDP.

Graduate medical education is the most important phase among the three stages of medical education. It links basic medical education and continuing professional development. It is also a critical period in acquiring meaningful knowledge, skills and professionalism. The residents should be able to develop the core common competencies on top of their specialozeds field's expertise, in order to function as independent and qualified physicians. Despite the obvious importance of graduate medical education, the system in Korea has been designed and executed to meet the needs of the hospitals in the perspective of manpower management, rather than to educate and empower the residents. As a result, graduate medical education in Korea lacks clear educational objectives and systemic, resident-centered curriculums. Yet, we have no accreditation body to evaluate graduate medical education programs. In order to normalize graduate medical education, an integrated and unified institution that manages the whole process of the graduate medical education is desperately needed. Special attention should be given to the role of medical schools in educating the core common competencies. The Korean Association of Medical Colleges, the Korean Institute for Medical Education and Evaluation, and the Korean Academy of Medical Sciences should cooperate intimately to establish a new organization for the systemic management and development of graduate medical education.

Background: To explore the safety, efficacy, and oncological outcome of 3-port laparoscopic radical cystectomy (LRC) compared to open radical cystectomy (ORC) in patients older than 75 years. Materials and Methods: From June 2010 to July 2014, we analyzed 16 radical cystectomies in patients older than 75 years (LRC group=8; ORC group=8). Demographic parameters, operative variables, and perioperative outcome in the 2 groups were retrospectively collected, analyzed, and compared. Results: Patients in both groups had comparable preoperative characteristics. A significantly longer operating time (476 vs. 303 min, P=0.0002) and less estimated blood loss (627 vs. 2,106 mL, P=0.021) were observed in the LRC group compared to the ORC group. Infection and ileus were the most common early complications after surgery. Patients who underwent ORC suffered from more postoperative infection (22.2% vs. 0.0%, P=0.054) and ileus (25.0% vs. 12.5%, P=0.521) than the LRC group, but the difference was not significant. Conclusions: Judging from this initial trial, 3-port LRC can be safely carried out in elderly patients. We suggest 3-port LRC as the primary intervention to treat muscle-invasive or high-risk nonmuscle-invasive bladder cancer in elderly patients with an otherwise relatively long life expectancy.

대학원대학은 대학원 과정만을 운영하는 대학교로 일종의 단설전문대학원이다. 본 논문은 대학원대학 도서관의 현황을 분석해보고, 문제점을 파악하여 이에 대한 개선방안을 제시하고자 하였다. 이를 위하여 대학정보공시, 대학도서관통계 등을 이용하여 대학원대학 도서관 현황에 대한 자료를 수집하였다. 이렇게 수집된 자료를 각종 법적기준과 권장기준과 비교분석함으로써 현황을 분석하였다. 그 결과 한국의 대학원대학 도서관은 시설부문을 제외한 모든 분야에서 매우 열악한 것으로 파악되었다. 이러한 현실은 대학원대학의 열악한 재정기반에서 기인하였고, 관련법령의 미비점이 이를 가중시킨 것으로 보인다. 이러한 문제점을 개선하기 위해서 관련법령을 제.개정하여 법적 최소기준을 제시하는 것이 필요하다. 동시에 정보공시제도를 보완하여 대학이 자율적으로 개혁을 추진하도록 유도하여야 한다. 마지막으로 이를 추진할 대학도서관 관련단체의 협력이 필요하다.

We developed ultra-accelerated quantum chemical molecular dynamics and spectroscopic characterization simulators for development of PDP materials. By combination of these simulators, realistic structure of PDP materials is drawn on the computer. Furthermore, based on the structures, various properties such as cathode luminescence spectrum and secondary electron emission, is successfully evaluated. The strategy of "Experiment integrated Computational Chemistry" using developed simulators will presented that has the potential in being powerful tool for designing the PDP materials.

Purpose: The purpose of the present study was to investigate the effects of toe wedges on the gait ability of adolescents with spastic diplegic cerebral palsy. Methods: Six adolescents with spastic diplegic cerebral palsy participated in this study. During the participants walked with- and without toe wedges, the gait ability was analyzed using the electronic walkway system. Gait parameters, including velocity, cadence, step length, stride length, single support time, and double support time, were collected and analyzed. Results: When the participants walked with toe wedges, there were significant improvements in gait velocity, cadence, and double support time compared to those without toe wedges (p<0.05). However, there were no significant differences in step length, stride length, and single support time. Conclusion: Toe wedges may have a positive effect on the gait ability of adolescents with spastic diplegic cerebral palsy. However, it is necessary to conduct high-quality studies to identify the effects of toe wedges.

The epidemiology of pancreatic neuroendocrine neoplasms (PNENs) in Asia has been clarified through epidemiological studies, including one conducted in Japan, and subsequently another in South Korea. As endoscopic ultrasonography (EUS) has become more widely accessible, endoscopic ultrasound-fine needle aspiration (EUS-FNA) has been performed in pancreatic tumors for which the clinical course was only monitored previously. This has enabled accurate diagnosis of pancreatic tumors based on the 2010 WHO classification; as a result, the number of patients with an accurate diagnosis has increased. Although surgery has been the standard therapy for PNENs, new treatment options have become available in Japan for the treatment of advanced or inoperable PNENs; of particular note is the recent introduction of molecular target drugs (such as everolimus and sunitinib) and streptozocin. Treatment for progressive PNENs needs to be selected for each patient with consideration of the performance status, degree of tumor differentiation, tumor mass, and proliferation rate. Somatostatin receptor (SSTR)-2 is expressed in many patients with neuroendocrine tumor. Somatostatin receptor scintigraphy (SRS), which can visualize SSTR-2 expression, has been approved in Japan. The SRS will be a useful diagnostic tool for locating neuroendocrine neoplasms, detecting distant metastasis, and evaluating therapy outcomes. In this manuscript, we review the latest diagnostic methods and treatments for PNENs.
