Purpose: Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP) is a small-vessel vasculitic disease that most often affects the skin. Abdominal symptoms precede the typical purpuric rash of HSP in 14~36%. It is a challenge to diagnose HSP in the absence of a rash, because there are no biologic tests that can identify HSP with certainty, so we tried to find out the characteristic features of HSP gastroenteropathy without purpura before diagnosis. Methods: This study included 82 children with HSP who had been admitted or visited outward of the Department of Pediatrics, Pusan National University Hospital from 1995 to 2000. The cases that the onset of purpura preceded or coincided that of abdominal pain were defined as purpura-positive group. The cases that the onset of abdominal pain preceded purpura more than 1 week and purpura was not presented till diagnosed as HSP gastroenteropathy were defined as purpura-negative group. We compared and analyzed the clinical features of the two groups by reviewing the medical records retrospectively. To ensure the diagnosis of HSP gastroenteropathy, we conducted upper GI series, abdominal ultrasonogram, abdominal CT, endoscopy and/or skin biopsy. Results: The number of cases of purpura-positive group and purpura-negative group were 72 and 10, respectively. There is no difference between two groups in the incidence of clinical symptoms and laboratory findings. Children with HSP gastroenteropathy had characteristic erosive or ulcerative lesions in the stomach or duodenum on esophagogastroduodenoscopy, or mural thickening of the small bowel on abdominal ultrasonogram, CT or upper GI series. Skin biopsy revealed leukocytoclastic vasculitis in 3 of them, although biopsy specimen was taken from any areas of normal- appearing skin. In purpura-negative group, 9 patients improved by steroid therapy. Conclusion: In purpura-negative group, there is no diagnostic feature on the laboratory findings and clinical features. Therefore, to diagnose HSP gastroenteropathy in patients with abdominal pain in the absence of the characteristic rash, careful observation of clinical features and laboratory data, and prompt application of available diagnostic tools such as gastrointestinal endoscopy, radiologic study and skin biopsy are recommended. Early use of corticosteroid may reduce the suffering in these patients.

Purpose - The self quality inspection which is mandatory in Republic of Korea can play an important role in promoting food safety, but the cost for self quality inspection is also a big burden especially for small businesses. In addition, excessive or duplicated inspection costs resulting from the standard gaps of various ministries and agencies ultimately effect negative social utility. Thus, this paper aims to suggest ways to improve the analysis of self quality inspection for the Ready-to-Eat Foods in terms of dried laver, in order to reduce costs caused by overinclusion. Research design, data, and methodology - The focus of interest is seaweed in Kimbab, which is to be exempted from the Vibrio parahaemolyticus test on the three grounds. First, existing literature provides little support for the necessity of performing a microbiological test. Second, laver products do not require the V.parahaemolyticus test by international standards such as the CODEX. Third, no case was found for seaweed products on the list of information on failed food items over the 2015~16 period. Results - Other types of seaweed such as exportable and seasoning seaweed are not subject to the test. Hence, exclusion of the V.pahaemolyticus test on seaweed is a valid point, bringing about large expected cost savings to many small businesses. Conclusions - Based on a complete survey of 75 food-testing agencies from March 20th to 30th, 2018, this paper finds that the proposed revision of the Kimbab test is likely to save an average of 130,000 won per business per year. Especially, in the case of the testing fee of Salmonella spp.(n,c,m,M), the cost difference by agencies was found to be up to five times. The regional gap in testing fees can be considered an unfair barrier. Accordingly, it is necessary to examine whether the testing fee is set at an appropriate level through the cost-extraction program proposed by the Ministry Food and Drug Safety. Hence, the survey results also point out that harmonization of testing fees charged by different food-testing agencies is appropriate with respect to transparency and efficiency.

In this paper, we described a measurement method of an EIRP(Effective Isotropic Radiated Power) of a WCDMA base station using a pilot channel in line-of-sight environments. Especially we measured it in real base station environments in order to apply this method to domestic base station inspection test. Estimated EIRP results from measured value is -2 dB lower than theoretical values, which is calculated by the data of transmit antenna. The deviation of -2 dB is verified as a polarization mismatch between the base station antenna and a receiver antenna, and it can be calibrated. Therefore, we verified that our measurement method could be an effective tool to measure an EIRP in WCDMA base station inspection test.

TMJ Osteoarthritis is a degenerative disease caused by overload on joint tissue, and often accompany with local tenderness on the joint, crepitus by mandibular movement, restriction of mandibular movement, and anterior openbite. In general, panoramic radiography, TMJ panoramic radiography, and transcranial radiography are conducted to diagnose osteoarthritis after clinical examination, however, these radiographic evaluations are limited in detecting minute bony changes of early pathologic lesion. The aim of this pilot study was to evaluate the limitation and usefulness of several TMJ imaging techniques, so we compare the findings from clinical examination, plain film radiographs, tomograph, and bone scan from 81 patients with temporomandibular joint disorder. The proportion of patients showing same findings in plain film radiographs, TMJ tomograph, and bone scan was high, however, it is desirable that clinician should conduct phased imaging examinations according to the clinical findings due to the possibilities of false negative findings in diagnosis of osteoarthritis.

Fuzzy reasoning was applied to sensory evaluation of cooked rice. A sensory attribute diagnostics was done in terms of tour kinds of attributes-texture, taste, odor and appearance which determine overall palatability. First, rating for the contribution level of each attribute to the overall palatability was asked as one of five scales-very important, important, moderate, slight and very slight. Secondly, the preference level of each attribute for a cooked rice sample was asked as one of five hedonic scales-excellent, good, fair, poor and very poor. Thirdly, the results of the scales were converted into fuzzy values and operated by fuzzy reasoning. Finally, the contribution and preference levels of the attributes were composed to infer the overall palatability of cooked rice sample.

The most noticeable aspect of progressive streaming is the media playback during its download through TCP to avoid a lengthy wait for a content to finish downloading. By employing TCP, it is usually possible to detect lost packets by using the checksum and sequence numbering functions of TCP Thereafter, we can recover the lost packets by the retransmission function of TCP. However, there must remain enough amount of media data in the recipient buffer in order to guarantee seamless media playback even during retransmission. In this paper, we propose an efficient algorithm for determining the initial buffering time before start of playback to guarantee seamless playback during retransmission considering the probability of client buffer under-flow. The effectiveness of the proposed algorithm will be proved through extensive simulation results.

The pungent principles of 20 Korean red peppers(Capsicum spp.) were analyzed by high performance liquid chromatography(HPLC) method. Capsaicinoids levels were considerable from 7.0mg/100g to 75.9mg/100g in Korean red peppers. The index value of the variety, ratio of capsaicin to dihydrocapsaicin was 0.8~1.1. This fact reveals that several varities of red pepper have existed in Korean. The sensory intensity of pungent principles was completely accordant with instrumental analysis result until 10ppm of capsaicinoids. The acceptance concentration of pungent principles was from 7.8ppm to 15.6ppm in Korean people.

Objective: glucometer is one of POCT(point-of-care testing) devices used by EMS. Accurate measurement value is important for patient decision making. Quality control is necessary for this, but most EMS are still using glucometer without quality control it. Therefore, management status and quality control status of glucometers used by 119 paramedics waswere investigated. Methods: 6 and 8 of glucometers and blood glucose test strips were submitted from 4 safety centers in 2010 and 8 safety centers in 2012, respectively. Glucometers submitted by local safety centers were analyzed in 2010 and 2012. The control glucometer, which was well managed at A University Hospital, was assumed to be accurate for at blood glucose measurement. Glucose values of various quality control materials control solutions were measured and analyzed using linear regression and Pearson's correlation test. Error rates were obtained via error tolerance range required by the 2011 ISO(International Organization for Standardization) guideline. For statistics, Excel and MedCalC programs were used. Results: mong 14 safety centers in the region, 4 centers(28.5%) in 2010 and 8 centers(57.1%) in 2012 submitted 6 and 8 glucometers. In the first evaluation in 2010, 2 out of 6(33.3%) glucometers were untestable due to error, and 45 out of 6(66.683.3%) blood glucose test strips' validity were expired. In the second evaluation in 2012, 1 out of 8(13.5%) glucometers were untestable due to lack of battery, and 2 out of 8(25%) blood glucose test strips' validity were expired. All correlation coefficients were above 0.989 in 2010 and above 0.997 in 2012. Error rates were generally high when using expired blood glucose test strips. Conclusion: Among 119 paramedics' guideline, quantity and operation status of POCT devices are well managed, but quality control is not. Therefore, it is necessary to add management status and quality control status of POCT devices to the EMS' field work guideline.
