  • Purpose: Conventional serum IgE assay was costly, required the skills of expert, and relied heavily on expensive equipment. Quantitative measurement of total IgE using Point of Care Test (POCT) device can be the solution for these limitations. This study evaluated and validated the reproducibility of ImmuneCheck IgE. Methods: This study included 120 patients of allergic diseases such as allergic rhinitis, asthma, drug allergy, food allergy, atopic dermatitis, or anaphylaxis. The reliability of POCT ImmuneCheck IgE was evaluated by comparing results from the naked eye and from the Q-Reader. Intratest reproducibility and intertest correlation were analyzed using intraclass correlation coefficient (ICC). Results: Of the 120 enrolled patients, 51 were males and 69 were females. The ages ranged from 19 to 84 years, with an average age of 51.5 years. The concentration of serum total IgE measured by Phadia ImmunoCAP IgE ranged from 5.95 to 5,000 IU/mL. ICC for Intratest reproducibility of ImmuneCheck IgE by naked eye and by Q-Reader were 0.991 (P< 0.001) and 0.989 (P< 0.001), respectively. In addition, intertest correlation between ImmuneCheck IgE and Phadia ImmunoCAP IgE results of naked eye and Q-Reader were 0.968 (P< 0.001) and 0.948 (P< 0.001), respectively. Conclusion: The ImmuneCheck IgE was reproducible and highly correlated with conventional Phadia ImmunoCAP IgE assay. This result suggests that ImmuneCheck IgE can be a useful tool for rapid and precise detection of total IgE.

  • Objectives The object of this study was to observe the favorable anti-arthritic effects of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) on Freund's complete adjuvant (FCA)-induced arthritic Wistar rats. Methods Rheumatoid arthritis was induced by intradermal injection of FCA, and 300, 150 or 750 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) were orally administered once a day for 14 days from 14 days after FCA treatments, and 15 mg/kg of dexamethasone was intraperitoneally administered as reference drug in this experiment. All rats were sacrificed at 14 days after continuous oral treatment of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) or intraperitoneal administration of dexamethasone, and changes on the body weight, knee circumferences, gross arthritis score, inflammatory tissue prostaglandin (PG) $E_2$ levels were monitored with cartilage collagen components and glucosaminoglycans compositions - chondroitin sulphate, heparan sulphate and hyaluronic acid in the present study. Results As results of FCA treatment, classic rheumatoid arthritis featuring dramatical decreases on the body weights, cartilage collagen contents and bone glucosaminoglycans-chondroitin sulphate, heparan sulphate and hyaluronic acid contents, with increases on the knee circumferences, gross arthritis scores and inflammatory tissue $PGE_2$ levels. However, these changes from FCA-induced rheumatoid arthritis were clearly reduced by treatment of dexamethasone and both two different dosages of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 and 150 mg/kg in the present study. Although FCA-induced arthritis were more favorably inhibited by treatment of dexamethasone 15 mg/kg as compared with Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg, marked decreases of body weights were detected in dexamethasone 15 mg/kg treated rats, and Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg showed similar preserve effects on the cartilage glucosaminoglycan compositions in this study. Conclusions The results obtained in this study suggest that over 300 and 150 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) showed favorable anti-arthritic effects on the FCA-induced arthritis mediated by suppression of $PGE_2$, a inflammatory mediator. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. Although overall anti-inflammatory effects Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg were lowered than those of dexamethasone 15 mg/kg treated rats, Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg treated rats showed similar preserve effects on the cartilage glucosaminoglycan compositions in this experiment.

  • Purpose: The purpose of this study was to evaluate the effect of healing abutment height and measurement angle on implant stability when using Periotest and AnyCheck. Materials and methods: 60 implants were placed into artificial bone blocks. After implant insertion, 2, 3, 4 and 5 mm healing abutments were installed on 15 specimens, respectively. Insertion torque value, implant stability test, Periotest value were measured. Insertion torque value was controlled between 45 - 55 Ncm. AnyCheck was used for measuring implant stability test and Periotest M was used for measuring Periotest value. Implant stability test and Periotest value were measured at the angles of 0 and 30 degrees to the horizontal plane. Measured values were analyzed statistically. Results: Insertion torque value had no significant difference among groups. When healing abutment height was higher, implant stability test and Periotest value showed lower stability. Also when measurement angle was decreased, implant stability test and Periotest value showed lower stability. Conclusion: When measuring stability of implants with percussion type devices, measured values should be evaluated considering height of healing abutments and measurement angle.

  • In this study, we have investigated the dose characteristics of PTW-LinaCheck designed to detect output of medical LINAC and discussed clinical use of the detector. The reproducibility, linearity, and dose rate dependency of the dosimeter were measured for photons of 6 and 15MV and the electrons of 4, 6, 9, 12, and 16MeV. To know the error ranges of the measured data in daily output measurement, the response variations due to geometrical setup errors were measured. As a result of measurement, the error range from the geometrical setup and the reproducibility was less than ${\pm}0.6%$ for given beam qualities in daily output measurement, where the errors from the linearity and the dose rate dependency were negligible. Finally, we concluded that the LinaCheck dosimeter has a good characteristics in terms of dose and setup convenience in daily output measurement. In addition we have shown an examples of clinical use of this dosimeter for measuring daily output more than 60 days.

  • Java specification states that all accesses to an object must be checked at runtime if object refers to null. Since Java is an object-oriented language, object accesses are frequent enough to make null pointer checks affect the performance significantly. In order to reduce the performance degradation, there have been attempts to remove redundant null pointer checks. For example, in a Java environment where a just-in-time (JIT) compiler is used, the JIT compiler removes redundant null pointer check code via code analysis. This paper proposes a technique to remove additional null pointer check code that could not be removed by previous JIT compilation techniques, via early null pointer check using an architectural feature called predication. Generally, null point check code consists of two instructions: a compare and a branch. Our idea is moving the compare instruction that is usually located just before an use of an object, to the point right after the object is defined so that the total number of compare instructions is reduced. This results in reduction of dynamic and static compare instructions by 3.21$\%$ and 1.98$\%$. respectively, in SPECjvm98 bechmarks, compared to the code that has already been optimized by previous null pointer check elimination techniques. Its performance impact on an Itanium machine is an improvement of 0.32$\%$.

  • 'Choyoung', a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2015. The cultivar 'Choyoung' has the leaves of medium width, long length and green color and a medium grain of brown color. The heading date of the cultivar 'Choyoung' was April 30 which was 2 days earlier than that of check cultivar 'Shinyoung'. Its tolerance or resistance to cold, wet injury, powdery mildew, and leaf rust was similar to those of the check cultivar. But the resistance to the lodging of cultivar 'Choyoung' was stronger than that of the check. The average forage fresh and dry matter yield of cultivar 'Choyoung' at milk-ripe stages were 40.5 and $15.7MT\;ha^{-1}$, respectively, which were similar to those (40.3 and $16.1MT\;ha^{-1}$) of the check cultivar. The silage quality of 'Choyoung' was higher than that of the check cultivar 'Shinyoung' in crude protein content (5.9%), while was similar to the check cultivar 'Shinyoung' in acid detergent fiber (33.9%), neutral detergent fiber (57.3%), and total digestible nutrients (62.2%). It showed a grain yield of $5.59MT\;ha^{-1}$, which was 38% higher than that of the check cultivar 'Shinyoung' ($4.05MT\;ha^{-1}$). This cultivar is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than $-10^{\circ}C$.

  • In CNG (Compressed natural gas) fuel supply line, whose main components are receptacle and check valve are used to charge high pressure gas to the tank of NGV (Natural gas vehicle). It is reported that the seal is separated occasionally form valve seat and results in blockage of gas flow. In this paper, MARC is used to investigate the reasons of seal separation and suggest design improvements. The static gas pressure distributions acting on the seal which calculated using FLUENT are considered to investigate accurate seal deformation behaviors. Deformed seal shapes are obtained for various amounts of seal interference and its location, gas pressure distributions and Young's modulus of the rubber used. The results showed that the reasons of seal separation problems are verified theoretically, and suggested examples of new design method. Therefore the present numerical methods can be applied in designing and performance analysis of rubber seals adopted in high pressure fluid machineries.
