  • For screening the appropriate field diagnostic techniques to failure of passive immunoglobulin transfer(FPT) in Korean-indigenous calves, 258 sera was examined by spectinophotometry for total protein(TP) and globulin(Glo), sodium sulfate precipitation test(SSPT), zinc sulfate turbidity test(ZSTT), and single radial immunodiffusion test(sRID). All calves aged within 6-week old. Morbidity and mortality to various diseases, mainly including enteric and respiratory disorders, were 18.9%(49) and 4.2%(11), respectively. FPT was 27,9%(72/258) when the cutoff point of TP was $4.5g/d{\ell}$ and among them the morbidity and mortality were 27.9% and 6.9%, respectively. FPT was 29.1%(75/258) when the cutoff point of Glo was $2.0g/d{\ell}$ and among them the morbidity and mortality were 29.0% and 6.9%, respectively. FPT was 13.1%(34/258) when the cutoff point of SSPT was 1+ and among them the morbidity and mortality were 67.6% and 23.5%, respectively. FPT was 19.7%(51/258) when the cutoff point of IgG with sRID was $1,000mg/d{\ell}$ and among them the morbidity and mortality were 41.1% and 11.7%, respectively. In addition, mean concentration of IgG with sRID tested was $2,150mg/d{\ell}$ at 3-day old but $1,100mg/d{\ell}$ at 9-days with $1,100mg/d{\ell}$. The results of the study were suggested that SSPT for FPT was the relatively reliable and convinient method for evaluating the immune status of calves(P<0.05).

  • Diagnostic X-ray system is general and basic medical equipment to be used in mostly medical organizations, but being bombed of radioactivity is a big weak point when irradiates a X-ray to the human body so that ICRP restricted the radiation exposure tolerance of the human body. In order to reduce being bombed, the many research and development is now advanced. A lots of diagnostic X-ray machines have currently used due to the increase of occurrence efficiency of X-ray and precisely the output control by using the inverter which is a high speed switching semiconductors. For getting the confidence of the X-ray machine, the same radiation occurrence, same evaluation, and same irradiation condition are necessary when evaluates X-ray irradiation. It is the most important part for the accuracy of the test result and the patient safety. This paper has produced the high voltage occurrence system of full-wave rectification method by using the LC resonance inverter, and evaluated the irradiation reproducibility in order to use it in diagnosis of the patient.

  • Food allergies affect 7~8% of infants and young children, and their prevalence appears to have increased in recent years. Food allergy refers to an abnormal immunological reaction to a specific food. These reactions can be recurrent each time the food is ingested. Food allergy manifests itself with a wide spectrum of clinical characteristics including IgE-mediated diseases as immediate reactions, non-IgE-mediated disorders as delayed reactions, and mixed hypersensitivities. As a consequence, the clinical picture of a food allergy is pleomorphic. A well-designed oral food challenge is the most reliable diagnostic test for infants and young children whose clinical history and physical examination point towards a specific food allergy. Food specific IgE antibody tests (RAST, MAST, skin prick test, Uni-CAP, etc) are an alternative tool to determine oral food challenge for IgE-mediated disorders, but not for non-IgE-mediated allergies. Moreover, parents often impose their children on unnecessary diets without adequate medical supervision. These inappropriate dietary restrictions may cause nutritional deficiencies. This review aims to introduce clinical perspectives of food allergy in infants and young children and to orient clinicians towards different strains of diagnostic approaches, dietary management, and follow-up assessment of tolerance development.

  • X-ray quality is identified numerically by half value layer(H.V.L) and the HVL is affected by the kVp and the amount of filtration in the useful beam. X-ray quality evaluated by H.L.D is influenced by kVp and filtration. Author had several experiments with phantom in diameter of 8 cm normal adult chest, for reduction of radiation dose of the patients in diagnostic radiology and got some results. 1. H.V.L is increased the thicker the filter and the higher the kVp. 2. If the kVp is increased from 60 to 120, the skin dose can be reduced as 34%(Skin dose of 60 kVp with 4 mmAl filter : 100%). 3. If the 4 mmAl filter with 60 kVp is added to x-ray tube, skin dose can be reduced as 23% than no filter. 4. Therefore high kVp and filtration can increase output to input dose ratio and 120 kVp and 4 mmAl filter were most effective for reduction of patient dose in chest radiography.

  • Objective : We analyzed 3 clinical cases to estimate the possibility of shanghanlun as a completed clinical text which has its own diagnostic system. Methods : We collected 3 cases treated by huang lian e jiao tang conducted by a practiced shanghanlun doctor and defined the conceptional meaning of each provisions by analyzing the application of them in each case. Results : Shanghanlun provisions dualized with Je Gang(提綱) and Jo Mun(條文) is the record of preceding factors which describe the phenomenon initiating the diseases. Conclusions : Rudimentarily a factor can bring about many outcomes, so if shanghanlun is structured record of the factors which can make a human sick from many diseases, it can be used as the completed clinical text only with those 113 prescriptions. Factors that shanghanlun recorded seem somewhat different from western conventional medicine because the field of each factors are very varied from biological phenomenon to psychological phenomenon. However it is not that weird because psychosomatic medicine in western conventional medicine also point out the factors come from mental, society and behavior.

  • Diagnostics membranes which were made of polyacrylonitrile were prepared for the measurements of blood glucose concentration. Final absorbances at 680nm through polyacrylonitrile diagnostic membranes were measured at various concentration of glucose in blood. It was found that the end-point results of varing absorbance values as time (K/S) had a linear relationship toward the blood glucose concentration. The effects of possible constituents in human blood on the glucose concentration measurements were examined. As a result, most of the chemicals did not affect seriously on the blood glucose measurements.

  • Kudoa septempunctata, a myxosporean parasite that infects olive flounder Paralichthys olivaceus is known to cause Kudoa food poisoning. Entire trunk muscle (ETM) is used for diagnosis of the parasite in fish and this method demands sacrifice of the host, causing a loss of commercial value. We developed a non-destructive method that uses a plastic syringe-style implanter to draw the sample, called the part-point muscle (PPM) sampling technique. We validated the PPM method in fish infected with K. septempunctata at the level detectable by the ETM method. We confirmed that the PPM method is equally sensitive in comparison to the ETM method for diagnosing K. septempunctata spores in olive flounder muscle. Our study also confirmed that the parasite is uniformly distributed in the dorsal muscle of infected fish. Over a period of 1 month, we observed no mortality of the host fish used for sampling by the PPM method. Thus, our studies demonstrate that the PPM sampling technique is an efficient, non-destructive method for diagnosing K. septempunctata in olive flounder.

  • Polyurethane diagnostic membranes were prepared to measure blood glucose level of diagnostics. Final absorbances at 680 nm through activated polyurethane membranes were measured at various concentration of glucose in blood. The end-point results of varing absorbance values as time (K/S) was found to have a linear relationship toward the blood glucose concentration. The effects of hematocrit on the glucose concentration measurements were examined. In low hematocrit, dose-response slope (DRS) values between gluose concentration and K/S values did not show the big differences compared to those in plasma. However, in high hematocrit (more than 40%) DRS values were considerably decreased.

  • This study is concerned with the meandering of plume axis in oceanic waters. The process is understood that it is a consequence of the differential contribution by the multiple harmonics of local velocity field to variances of center of mass of crossplume as a function of distance from the source point. A diagnostic model is proposed which is aimed to delineate the eddying motions and furthermore the amplified meandering of plumeaxis. From the data base of dye plumes, wave lengths of meandering eddies are estimated to range between 5.5 to 60.3 (m) in coastal surface waters. A numerical simulation is conducted to predict the concentration field of meandering plume.

  • A new type of diagnostic membranes based on methoxyethoxy and trifluoroethoxy co-substituted polyphosphazene has been prepared to measure blood glucose level of diabetics. Final absorbances at 680 nm through activated polyphosphazene membranes were measured at various concentration of glucose in plasma or blood. The end-point results of varing absorbance values as time (K/S) was found to have a linear relationship toward the blood glucose concentration. The effects of substitution rates with hydrophilic groups and hydrophobic groups on the measurements of glucose concentration were studied. Dose-response slope (DRS) values between glucose concentration and K/S values increased as the hydrophilic substitution rates increased. However, in more than 30% of the substitution rates, it was difficult to measure exact concentration level of glucose because DRS increased rapidly.
