Objectives: Traditional Korean medicine (TKM) has been supplied as part of a national health care system in South Korea under a dual medical system, however it has been difficult to mix western medicine and TKM medical practices in existing hospitals. For the objective of innovative integration between them, Comprehensive and Integrative Medicine Hospital were founded in Daegu, South Korea. Here, we discussed the clinical outcomes of cancer patients who received integrative cancer treatment (ICT). Methods: A total of 678 patients previously diagnosed with cancer were retrospectively checked in our institution for 2 years. After applying inclusion/exclusion criteria, 573 patients were eligible for the final analysis. The overall survival (OS) of these patients in the aftercare period were determined. We looked at how clinical factors and treatments including chemotherapy, complementary and alternative medicine (CAM), and TKM affected the OS. Results: At the first visit, 212 subjects had no evidence of disease after tumor resection and 355 ones with advanced cancer, who receiving ICT including chemotherapy, CAM, and TKM showed better OS compared to the CAM including TKM or the best supportive care (median OS = 216, 78, and 46 days, respectively). The median OS was not reached in TKM only, even though the sample size was small (N=12). Even after adjusting for clinical factors associated to liver, renal, and hematologic manifestation, ICT still remained significant. Conclusions: We demonstrated that ICT might be beneficial for advanced cancer regardless of the performance status, liver and renal function, since it positively affected the OS.

This review introduces advances in clinical and pre-clinical single photon emission computed tomography (SPECT) and positron emission tomography (PET) providing noninvasive functional images of biological processes. Development of new collimation techniques such as multi-pinhole and slit-slat collimators permits the improvement of system spatial resolution and sensitivity of SPECT. Application specific SPECT systems using smaller and compact solid-state detector have been customized for myocardial perfusion imaging with higher performance. Combined SPECT/CT providing improved diagnostic and functional capabilities has been introduced. Advances in PET and CT instrumentation have been incorporated in the PET/CT design that provide the metabolic information from PET superimposed on the anatomic information from CT. Improvements in the sensitivity of PET have achieved by the fully 3D acquisition with no septa and the extension of axial field-of-view. With the development of faster scintillation crystals and electronics, time-of-flight (TOF) PET is now commercially available allowing the increase in the signal-to-noise ratio by incorporation of TOF information into the PET reconstruction process. Hybrid PET/SPECT/CT systems has become commercially available for molecular imaging in small animal models. The pre-clinical systems have improved spatial resolution using depth-of-interaction measurement and new collimators. The recent works on solid state detector and dual modality nuclear medicine instrumentations incorporating MRI and optical imagers will also be discussed.

Objectives: The aim of this study was to investigate the attitude toward the oriental hospital among 1,234 outpatients. Methods: A questionnaire about the general characteristics of patients, the decision-maker of use and the reason of choice or alteration was implemented. Results: The results of this survey as follows: Among outpatients 56.4 % were female in sex, 25.6 % were below 9 years of age; in educational level, 50.1 % were college graduates. Among outpatients, 33.6% chose the oriental hospital as their first choice and the rest were recommended by other persons. The recommenders were mostly relatives(73.9 %), female(73.4 %), young(30-39 years old, 40.1 %), high educational level (above the college, 54.9 %) people. 37.8 % among outpatients were secondary selection after the western medical clinic for the same symptom and sign. 7.0 % were the concomitant users of both therapies. 62.8 % among the concomitant users did not notify the western doctor about the dual therapies. The reasons they did not notify their Western doctors were 'be afraid of western doctor s bias' (42.6 %), 'no special reason' (29.6 %). Conclusions: The appropriate transfer system between oriental and western clinic must be constructed and the proper recognition about dual therapies will be needed among patients and doctors who practice both kinds of medicine.

This paper proposes an adaptive technique for the cardiac output regulation of a pendulum type electromechanical TAH. This techinque, which consists of two RLSE's and two PASTC' 5, performs Its controllability over the TAIB so that the m(RAP) and m(LAP) values re- main close to their desired values under she assumption that the variation of m(RAP) and m (LAP) are dominated by the variation of C.0. and the difference between the left and right ventricular output, respectively. To evaluate the performance of the proposed control system, a simulation is performed by using a human model which contains physiologic, drug and treatment, artificial heart and noise models. As a result, dual adaptive controller showed that abnormal m(LAP) and m(RAP) could be recovered to the normal range within 10minute and maintained desired value in steady state. The operation of this controller prored to be robust in spite of the rapid variation of human status.

Objectives: Korea has a dual medical system where traditional Korean Medicine (KM) and Western Medicine (WM) exist au equal terms with exclusive practice boundaries. The aim of this study was to identify complementary and substitute relationships between KM and WM in Korea. Methods: The data of 19,413 respondents were collected from the 2009 Korea Health Panel dataset. General characteristics and the medical utilization of respondents were analyzed descriptively. the Univariable Analysis was used to compare the factors that affected KM and WM utilization, and the Multivariable Analysis was applied to identify complementary or substitute relationships between the respondents' choices for KM and WM. The data were analyzed by the seven disease groups; diseases of nervous system, circulatory system, respiratory system, digestive system, skin and subcutaneous tissue, musculoskeletal system, and connective tissue, injury, poisoning and others. Results: 13.6% and 76.9% of respondents used KM and WM respectively last 12 mouths. 12.7% used both, and 0.9% used KM only. In overall, respondents who visited KM institutions used also WM. However, according to the analysis of choices of medical institutions, non-pharmacological KM treatment and WM has been used as a substitute for another in the diseases of the skin and subcutaneous tissue, diseases of the musculoskeletal system, and connective tissue, injury, poisoning and others. Conclusions: Despite some exceptional disease areas, Korean people use KM complementarily to WM, and this result can rationalize the recent Korean government policies encouraging the cooperation of KM and WM. This study can he used for the future policies development for KM service delivery.

This study investigates research trends on the Convergence of Chinese and Western Medicine (中西醫匯通, CCWM), by first defining the concepts and the scope of this emerging field, identifying different types of convergence, and suggesting methods to evaluate the process. The author investigates the relationship of CCWM to the Self-Strengthening Movement and the doctrine of Zhongtixiyong (中體西用). Lessons that Korean Medicine (KM) can learn from this approachto help establish relationship between Korean and Western Medicine, are investigated. Proponents of CCWM suggest different types of convergence such as Zhongzhongcanxi (衷中參西), Zhongxizhezhong (中西折衷), and ZhongyiKexuehua (中醫科學化), to accommodate the change in the power dynamics between Chinese and Western medicines. The rigid dual medical system in Korea significantly hinders the potential for convergence. The current system is based on the relativistic model in which the scope of practice for the KM doctor and the Western Medicine doctor are mutually exclusive. Philosophically, the convergence of East-West medicine can be supported by pluralism and monism, while relativism sees it as impossible. A conservative pluralistic model might consider Bogu (補救) of Eastern Medicine, while a more progressive pluralistic model might build a New Medicine which combines the knowledge and techniques of Eastern and Western medicines. An example of monistic model is CAM (Complementary and Alternative Medicine), which aims to scientifically verify the efficacy and safety of the Eastern therapeutic practices and integrate them into Western medicine. This article proposes that as communication and fusion between medical disciplines are essential virtues of contemporary scholarly development, a change that enables the convergence of East-West medicine is needed.
