The color sorting technique utilizing the image processing method is very applicable tool to analyze motion of a free-falling object in many agricultural and industrial research fields. In the present study, we have developed an image processing system and algorithm to sort good quality rice grains effectively from the bad ones. The system employs a high speed rate line-scan CCD camera with 2K-pixels and worked with a high speed DSP and FPGA in-line. It can accumulate acquired line-scan image data and visualize each grain image clearly. As a result, we can easily calculate the number of pixels occupied by grain(=grain size), gray level and its correct position by visualizing grain images rapidly.

Salivary gland fistula is a fistula involving a salivary gland or duct. Most salivary gland fistulae are related to the parotid gland. Submandibular fistulas on the other hand are very rare entities with only few cases reported till date. Most of submandibular gland fistulas are known to be congenital in origin, but acquired cases can rarely occur. Herein, we report a rare case regarding submandibular gland fistula in dermatologic literatures. A 53-year-old woman presented with erythematous patch with painful subcutaneous mass on lt. side of neck, which had developed over the course of 3 weeks. Symptom persisted despite treatment with empirical oral antibiotics. The computed tomography neck scan revealed enhancing tubular structure from submandibular gland to anterior aspect of platysma muscle and abscess, which was consistent with submandibular gland fistula. The patient was managed conservatively with antibiotic therapy for 3 months and the symptoms improved markedly. Submandibular gland fistula is rare condition and might be easily misdiagnosed, because it usually presents nonspecific symptoms like painful neck swelling. Accurate diagnosis may be achieved by means of through clinical manifestation, radiographic findings, and sometimes surgical exploration. Dermatologist should be kept in mind the possibility of a submandibular gland fistula when a painful mass arising in the neck does not respond to initial treatment.

<P><B>Abstract</B></P> <P>Korea has own programs toward DEMO and fusion reactors that will require further improved DEMO blanket and energy utilization systems. Primary goals of DEMO blanket development in Korea are to develop and verify the integrated blanket design tools; to develop blanket materials, cooling and tritium fuel cycle technologies; and to develop and evaluate fabrication and joining technologies. The concept of helium-cooled ceramic reflector (HCCR) blanket is adopted to be tested in ITER as Test Blanket Module (TBM). Currently, the design and R&D activities are mainly performed through the ITER TBM program in Korea. It is expected to demonstrate the major objectives of the breeding blanket: extraction of heat from burning plasma, tritium self-sufficiency and its integrity within the whole systems considering safety features. Although TBM program will provide very essential data and experience, there will be a considerable technical gap from DEMO blanket. This paper presents the technical gap in the main technical categories of the breeding blanket based on the experience of the development of HCCR TBM and breeding blanket. It is found that still about 60–70% of the DEMO blanket technology can be achieved through the HCCR TBM depending on the technology maturity level, and some ways to DEMO blanket from HCCR TBM are proposed.</P>

Autophagy functions in cellular quality control and metabolic regulation. Dysregulation of autophagy is one of the major pathogenic factors contributing to the progression of nonalcoholic fatty liver disease (NAFLD). Autophagy is involved in the breakdown of intracellular lipids and the maintenance of healthy mitochondria in NAFLD. However, the mechanisms underlying autophagy dysregulation in NAFLD remain unclear. Here, we demonstrate that the hepatic expression level of Thrap3 was significantly increased in NAFLD conditions. Liver-specific Thrap3 knockout improved lipid accumulation and metabolic properties in a high-fat diet (HFD)-induced NAFLD model. Furthermore, Thrap3 deficiency enhanced autophagy and mitochondrial function. Interestingly, Thrap3 knockout increased the cytosolic translocation of AMPK from the nucleus and enhanced its activation through physical interaction. The translocation of AMPK was regulated by direct binding with AMPK and the C-terminal domain of Thrap3. Our results indicate a role for Thrap3 in NAFLD progression and suggest that Thrap3 is a potential target for NAFLD treatment.
