Korean rice industry is facing new challenge. Nowadays, rice price is ever rising since last year. Difference between domestic price and international price is also ever decreasing and korean rice has chance to win over foreign rice because of better quality and low price. Now is the time to discuss on tariffication of rice import. Even if Korea follows modality of DDA, Korean rice market does not give in to foreign rice. On the other hand, Korean policy makers should make efforts to find way for grain sovereignty.

Ewing's sarcoma is a neoplasm of the undifferenciated small round cells, which generally affects the bone and deep soft tissues of children and adolescents. We present a case of gastric Ewing's sarcoma; a 35-year-old female who had no symptoms. While she was at a routine medical checkup, a protruding mass in her gastric antrum was incidentally found on esophagogastroduodenoscopy. Endoscopic ultrasonogram showed a submucosal mass on the same lesion and a laparosopic wedge resection was done. Pathologic gross findings showed a granular grape appearance tissue and histoloigc examination revealed a small round cell tumor with CD 99 immunoexpression positive. In general, a combined modality therapy for Ewing's sarcoma such as surgical resection with chemotherapy, is accepted as an effective method. However, this patient had no adjuvant chemotherapy after surgery and she has no recurrence for eleven months.

FDG PET is a functional imaging modality whose ability to detect lesions is directly based on a change of the glycolytic metabolism of targeted tissues, may be advantageous over other techniques. Combined with excellent image qualify, high spatial resolution, and whole body imaging capability, it has become popular as a new approach in the evaluation of patients with various malignancies. Initial staging of nodal and extranodal lymphoma using FDG PET has been proven to be at least equal or superior to conventional imaging modalities. For the assessment of treatment responsiveness, FDG PET has a major impact on the management of patients in differentiating residual lymphoma from treatment related benign changes. Residual FDG uptake after the completion of chemotherapy is a good predictor of early relapse. However, it seems that the absence of FDG uptake in tumor mass may not exclude minimal residual disease causing later relapse. In the early evaluation of treatment response only after a few cycles of chemotherapy, FDG PET may have a promising role in identifying non-responders who could benefit from a different treatment strategy. At present, FDG PET appears to be the cost-effective, diagnostic modality of choice in the management of lymphoma patients. The role of FDG PET based-systems in terms of affecting long-term prognosis and survival benefit should be further elucidated in future prospective studios.

Today, ultrasound imaging is being widely used to assess soft tissue lesions in the maxillofacial region. However, ultrasound investigations of intra-osseous lesions are rare, especially for tumors of the jaws. This report emphasized the capability of this useful imaging modality in identification of the characteristics of malignant conditions involving the bone. Mesenchymal chondrosarcoama, one of the unusual malignant conditions of the jaw, was presented in a young male with significant facial swelling. Different imaging modalities parallel with the histopathologic investigation confirmed the diagnosis. Interestingly, destruction of the bony cortex and new bone formation with a characteristic "sun ray appearance", highly suggestive of sarcomas, was manifested on the ultrasonograph. Thus, this report presented the ultrasonographic features of chondrosarcoma of mandible and considered the ultrasonography to be a useful imaging modality to evaluate intra-osseous jaw lesions.

Dealing with existential concerns experienced by patients is an important part of palliative care. Interventions that use the life review method to encourage patients to reminisce about their lives can help them find new positive meanings, promote ego integrity, and reduce emotional suffering. Not everyone has positive memories when they look back on the past, however. This poses a limit on the effectiveness of the life review method for healthcare providers working in palliative care contexts. In this study, we discuss the limits of life review and suggest imagery rescripting as a new modality constituting a psychotherapeutic approach to deal with negative memories safely and effectively.

Purpose: Pilon fracture has several serious complications such as joint stiffness, arthrosis and delayed angular deformity. We report short-term results of new treatment modality using distracted dynamic external fixators and early controlled ankle motion. Materials and Methods: Eight cases of severe pilon fractures for which we tried small plate fixation and additional distracted dynamic external fixators from July 2007 to June 2009 were included. Half passive continuous ankle joint motion was allowed under free hinged ring fixators after the operation. The external fixators were removed after two or three months from the surgery. We investigated joint space by radiograph, joint pain, range of motion, patient's satisfaction of treatment protocol. Results: Joints were distracted when external fixators were applied and mean 28% of space loss developed after removal of external fixators. In most of cases, satisfactory alignments were maintained. Regarding range of joint motion, mean dorsiflexion angle was 15 degrees and mean plantarflexion angle was 32 degree in the condition of wearing external fixators. There was mean 8% reduction of range of motion but no further progression of ankle stiffness after removal of external fixators. Dorsiflexion was not improved after that, but plantarflexion angle was improved 10% even after removal of external fixators. Patients were generally in compliance with the treatment protocols with high level of satisfaction. Conclusion: We got good results with distracted dynamic external fixators and early continuous half-passive joint motion for pilon fractures in terms of joint pain and range of motion. Therefore we suggest this new protocol as an alternative modality for severe pilon fractures.

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.

이 논문은 칼 맑스의 선언문과 폐정 개혁문의 모달리떼와 그 상징성에 대한 연구이다. 이를 위한 텍스트로는 칼 맑스와 프리드리히 엥겔스의 공산 동맹 선언문과 동학 농민군의 폐정 개혁안을 채택했다. 이 선언문과 개혁문은 이 논문에서 1800년대의 철학적 실천담론을 모달리떼 양상으로 전개하며 기호학적 의미에서 그 공통의 상징성을 도출하고, 소유와 소외 그리고 계급에서 자유로워지는 민주주의를 향해 전진하는 사상적 흐름에 그 촛점을 맞추고 있다. 궁극적으로 동시대의 숨결 속에서 발표된 이 두 선언문은 감시와 처벌이라는 비인륜적 정책에 대한 고발장이다. 1일 2회 교회에서의 공간이 공장으로 바뀌고, 자본과 노동으로 2분법적 사고로 갈라치기 해서 이 범주 안으로 몰아넣는 행위가 마치 사회 윤리인 냥 치장되었으며, 사냥하는 식의 강요는 처벌 방식으로 이루어져 더 이상 사람이 존재하기 힘든 구조가 제도화 되어버린 현상에 대한 대항이다. 이 사냥의 틀을 깨부수려는 혁명운동이 바로 위 두 선언문으로 나타나며 칼 맑스는 자신의 존재를 '영원한 난민'의 위치에 둠으로서 공산동맹 선언을 통해 이루고자 한 유토피아의 절정을 완성하며, 동학농민군은 전봉준의 재판 취조과정에서 전개되는 그의 자유함에서 죽음을 택함으로써 자신은 물론 민중의 혁명정신을 완성한다. 동서양에서 동시에 폭발한 억압의 형태는 지배와 통치의 자본에 대한 철퇴이며, 이에 대한 새로운 대안이 '사람이 가장 큰 자본이다'로 새로운 패러다임 구축을 가능하게 하는 원천적인 철학적 배경이 된다는 점에서 이 논문은 그 의의를 ?고 있다.

Peptide imaging is a new diagnostic modality in nuclear medicine. $^{111}In$-pentetreotide ($Octreoscan^R$) is the first commercially available peptide radiopharmaceutical. This review article presents the results of previous studies using $^{111}In$-pentetreotide for several disease states, including neuroendocrine tumors, breast cancer and malignant lymphoma. The use of hand-held probe during surgery and the preliminary results of radiotherapy using radiolabeled somatostatin analogues are also reviewed. It can be concluded that somatostatin receptor scintigraphy is a promising diagnostic tool for localizing primary tumors that express receptors for somatostatin, staging secondary spread of tumor tissue, following up after therapy and identifying patients who may benefit from therapy with unlabelled or radiolabeled octreotide. The somatostatin receptor imaging will stimulate the development of new radiopharmaceuticals for other receptors and enhance the therapeutic use of radiolabeled peptides.

Many circular distributions are known to be not only asymmetric but also bimodal. Hidden truncation method of generating asymmetric distribution is applied to a bivariate circular distribution to generate an asymmetric circular distribution. While many other existing asymmetric circular distributions can only model an asymmetric data, this new circular model has great flexibility in terms of asymmetry and bi-modality. Some properties of the new model, such as the trigonometric moment generating function, and asymptotic inference about the truncation parameter are presented. Simulation and real data examples are provided at the end to demonstrate the utility of the novel distribution.
