  • This study was conducted to investigate yield of extract, total phenolic compounds content, electron donating activity, nitrite scavenging activity, superoxide dismutase like activity of the radish leaves (Raphanus sativus L.) extracts. Radish leaves extracts were prepared using water extraction, 50% ethanol extraction and 50% methanol extraction. The yield of Kwandong radish leaves extracts without blanching treatment (DRLK) was $26.56{\sim}32.56%$ and the extract yield of Minongdanbaek radish leaves without blanching treatment (DRLM) was $34.34{\sim}36.90%$. On the other hand, the yield of samples with blanching treatment was a lower range value of $18.70{\sim}23.56%$ than samples without blanching treatment. In the total contents of phenolic compound, samples with and without blanching treatment were $49.1{\sim}59.4mg/g\;and\;53.41{\sim}62.08mg/g$, respectively. Minongdanbaek radish leaves extracts (DRLM, BDRLM) showed higher contents value than Kwandong radish leaves extracts (DRLK, BDRLK) in the total phenolic compounds. Samples without blanching treatment showed electron donating activity above 80%, nitrite scavenging activity of $36.63{\sim}51.17%$ and superoxide dismutase like activity of $38.53{\sim}45.38%$. Generally, Kwandong samples showed a little higher activity more than Minongdanbaek samples in the electron donating activity, nitrite scavenging activity and superoxide dismutase like activity. Also, radish leaves extracts without blanching treatment showed high physiological activities.

  • Purpose: The Levey-Jennings chart controlled measurement values that deviated from the tolerance value (mean ${\pm}2SD$ or ${\pm}3SD$). On the other hand, the upgraded Westgard Multi-Rules are actively recommended as a more efficient, specialized form of hospital certification in relation to Internal Quality Control. To apply Westgard Multi-Rules in quality control, credible quality control substance and target value are required. However, as physical examinations commonly use quality control substances provided within the test kit, there are many difficulties presented in the calculation of target value in relation to frequent changes in concentration value and insufficient credibility of quality control substance. This study attempts to improve the professionalism and credibility of quality control by applying Westgard Multi-Rules and calculating credible target value by using a commercialized quality control substance. Materials and Methods : This study used Immunoassay Plus Control Level 1, 2, 3 of Company B as the quality control substance of Total T3, which is the thyroid test implemented at the relevant hospital. Target value was established as the mean value of 295 cases collected for 1 month, excluding values that deviated from ${\pm}2SD$. The hospital quality control calculation program was used to enter target value. 12s, 22s, 13s, 2 of 32s, R4s, 41s, $10\bar{x}$, 7T of Westgard Multi-Rules were applied in the Total T3 experiment, which was conducted 194 times for 20 days in August. Based on the applied rules, this study classified data into random error and systemic error for analysis. Results: Quality control substances 1, 2, and 3 were each established as 84.2 ng/$dl$, 156.7 ng/$dl$, 242.4 ng/$dl$ for target values of Total T3, with the standard deviation established as 11.22 ng/$dl$, 14.52 ng/$dl$, 14.52 ng/$dl$ respectively. According to error type analysis achieved after applying Westgard Multi-Rules based on established target values, the following results were obtained for Random error, 12s was analyzed 48 times, 13s was analyzed 13 times, R4s was analyzed 6 times, for Systemic error, 22s was analyzed 10 times, 41s was analyzed 11 times, 2 of 32s was analyzed 17 times, $10\bar{x}$ was analyzed 10 times, and 7T was not applied. For uncontrollable Random error types, the entire experimental process was rechecked and greater emphasis was placed on re-testing. For controllable Systemic error types, this study searched the cause of error, recorded the relevant cause in the action form and reported the information to the Internal Quality Control committee if necessary. Conclusions : This study applied Westgard Multi-Rules by using commercialized substance as quality control substance and establishing target values. In result, precise analysis of Random error and Systemic error was achieved through the analysis of 12s, 22s, 13s, 2 of 32s, R4s, 41s, $10\bar{x}$, 7T rules. Furthermore, ideal quality control was achieved through analysis conducted on all data presented within the range of ${\pm}3SD$. In this regard, it can be said that the quality control method formed based on the systematic application of Westgard Multi-Rules is more effective than the Levey-Jennings chart and can maximize error detection.

  • In order to evaluate the nutritive value of the forage plants in South Sulawesi, Indonesia, 266 samples (61 grasses and 65 legumes grown in the dry season, 60 grasses and 80 legumes grown in the rainy season) were collected from the highland and lowland in 1998 to 2000, and were subjected to the determination of chemical composition and digestibility. The least-squares analysis of variance demonstrated that the in vitro dry matter digestibility (IVDMD) of grasses was not significantly affected by season or altitude. On the other hand, the some proximate components and cell wall components were significantly affected by season and altitude including the season${\times}$altitude interaction. For the legumes, the in vitro neutral detergent fiber digestibility (IVNDFD) and cellulose content were significantly affected by season. On the other hand, the ether extract (EE) content was significantly affected by season and altitude. The interaction of the season${\times}$altitude for IVDMD, of the year${\times}$season for some proximate components and of the year${\times}$season and the season${\times}$altitude for some cell wall components were significant. These results indicate that the forages grown at highland in dry season have a relatively high quality. The means of the total digestible nutrient (TDN) content estimated from IVDMD in grasses and in legumes were 50.3% and 57.4%, respectively, and the crude protein contents were 7.7% and 17.6%, respectively. The correlation coefficients between IVDMD and the contents of crude fiber, neutral detergent fiber and acid detergent fiber were relatively high in all of forage plants, suggesting that these components would provide an accurate prediction of digestibility or TDN content. A close relationship between IVNDFD and lignin content indicates that the lignin would be the most accurate predictor of cell wall digestibility.

  • In order to establish fundamental data for the betterment of Polyester microfiber fabric handle, a study by using fixed warp of ITY yarn samples with P/F, DTY, and ITY weft yarns was performed. For this purpose the samples of total 27 kinds were prepared. That is, each sample yarn was twisted in three ways and for each twisted yarn the fabric structures were modified in three ways, plain, twill, and satin. The examination was done by focusing on the point of the change of handles and the characteristics of the mechanical properties of the samples with the change of yarn and the fabric structure. The handles and the mechanical properties were examined with the KES-F system suggested by Kawabata. The results were as follows : 1. WT and MIU increased with increasing the twist. By comparing WT and MIU by yarn, DTY was higher than P/F. It appeared that twill and satin were higher than plain. 2. The bending rigidity change in DTY with increasing the twist was not significant, however in P/F it appeared apparently decreased with increasing the tlvist. Also, it appeared that when using P/F as weft the bending rigidity was higher than when using DTY and the twill structure appeared higher than the satin structure. 3. In shear force the increasing rates of plain and the twill were higher than satin. When DTY and P/F were used as weft, the shear force was higher in ITY and DTY than in P/F case. 4. Koshi appeared higher in the order of plain, twill and satin. When DTY and P/F were used as the weft Koshi increased with increasing the twist in plain, however in twill and satin it appeared to decrease. In hand value ITY(=7.5) appea.ed to be highe. than DTY and P/F(=6.5). 5. In all cases Shinayakasa decreased with increasing the twist. The hand values observed that satin was =4, twill was =3, and plain was =1.5. 6. Fukurami showed no significant change with increasing the twist in DTY, however in P/F and ITY it decreased.

  • Purpose: The purpose of this study was to develop an assistant device for the promotion of bag-valve-mask ventilation based on a non-equivalent control group pre-test and post-test design. Methods: The experimental tool was a mask assistance device developed by the researchers. Data were analyzed using SPSS 21.0 with the cardiopulmonary resuscitation (CPR) evaluation program from August 18 to 30, 2016. The research tools included general, hand-related, and ventilation-related characteristics. Results: Before and after using the mask assistance device, the tidal volume increased by 64 mL (p<.001) from 461.76 mL to 525.86 mL. The tidal volume for control was 477.86 mL, and there was a statistical difference (p<.05). The ventilation frequency in device users was 10 times per minute for a total of 20 ventilations with before 10.65 after 10 times, and that of the control group was before 10.36 times after 10 times; there was no difference in both groups(p>.05). The accuracy of the assistance device was $81.72{\pm}30.86%$, which was a very high value. However, the accuracy of ventilation in the control group with no assistance device was $18.97{\pm}32.44%$, which was a very low accuracy rate. Conclusion: This study's results suggested utilizing the newly-developed mask assistance device in CPR, and showed increases in tidal volume and accuracy of ventilation using the bag-valve-mask ventilation equipment. The general and hand-related characteristics did not have any effect, so the use of the device proved to increase the efficacy in all users.

  • The purpose of this study was to identify HACCP-based CCP and CP from the microbial quality assessment on the process of side dish (stir-fried dried-shrimp with garlic stems) production in the meal service operation for the elderly. Total plate counts (TPC) of fresh garlic stalks were $7.80{\times}10^{3}$ CFU/g and they were above the standard value of microbial growth potential. The TPC, Coliform and E.coli were not detected in the dried shrimps. The TPCs after rinsing and slicing the garlic stems were $2.5{\times}10^{2}$ CFU/g and $5.5{\times}10^{2}$ CFU/g, respectively. The TPC number of cook’s hand and cutting board were also exceeded the standard limit with values of $2.2{\times}10^{2}$ CFU/g and $10.0{\times}10$ CFU/g, respectively. However, the TPC, Coliform and E.coli were not detected in the other cooking instruments. The identified CCP in inspection step was fresh garlic stems and that of prepreparation step was slicing the stems after blanching. Cook’s hand and cutting board were also verified as CCP and the other steps in cooking process and utensils tested were identified as CP’s. These result’s suggest that it is important to control the microbial contamination of raw materials at purchasing step and the sanitary education program should be developed for the employees for continuous supplement of safe and sound meal service for the elderly.

  • Hand deboned and mechanically deboned chicken meat were produced from domestic broilers and spent layers. Meat yield, chemical composition, functional characteristics, stability during storage, and microbiological properties were investigated Chicken patties and frankfurters were also manufactured by varying the relative proportion of MDCM to HDCM as raw materials, ana their palatability, shelf-life and textural properties were evaluated. The obtained results were as follows: 1) 35% of carcass wt was recovered as HDCM and 45% as MDCM, total meat yield reaching 80% of carcass wt. 2) Moisture, protein, fat, ash and Ca content of MDCM were 65, 12, 20, 1.7 and 0.2-0.4%,respectively. MDCM was higher in fat, ash and Ca, but significantly lower in moisture and protein. Total pigment content of MDCM was 2.5 times higher than that of HDCD such high content being attributed to the increased inclusion of hemoglobin. 3) The emulsifying capacity (ES) of MOCM per g meat was only 70% that of HDCM. but when ES was expressed on unit g of protein basis MDCM showed even higher ES than HDCM primarily due to tile higher proportion of salt soluble protein fraction. 4) Since the TBA values of MDCM increased rapidly after 4 weeks of frozen storage at -20$^{\circ}C$, the maximum possible storage period of MDCM is estimated to be about 4 weeks. 5) Total microbial counts of MDCM was approximately 1.8${\times}$10$\^$6/g/, showing no great difference from HDCM or red meat. 6) Chicken patty containing MDCM showed gradual increase in TBA value during frozen storage, but its storage up to 8 weeks presented no problems in flavor stability. 7) Color score an4 total palatability of chicken Patty were best for the product containing 30% MDCM. It was also concluded that MDCM can be included in the patties up to 50% of total meat with good results, but more than 70% was not recommended 8) The formulation of MDCM up to 50% in frankfurter gave quite satisfactory acceptability and textural properties comparable to frankfurter made of 100% MDCM, but the inclusion of more than 70% MDCM was not recommended 9) The TBA value of frankfurter containing MDCM did not increase to any great extent until 4 weeks of storage at 4$^{\circ}C$, indicating no unique problems in flavor instability compared to regular frankfurter. 10) It was concluded that processed meat products such as patties and frankfurters containing MDCM up to 30-50% of total meat ingredients gave satisfactory results in color, texture and palatability, comparable to regular products.

  • Purpose: The purpose of paper is to implement software to visualize brain fiber tract using a 24-bit color coding scheme and to test its feasibility. Materials and Methods: MR imaging was performed on GE 1.5 T Signa scanner. For diffusion tensor image, we used a single shot spin-echo EPI sequence with 7 non-colinear pulsed-field gradient directions: (x, y, z):(1,1,0),(-1,1,0),(1,0,1),(-1,0,1),(0,1,1),(0,1,-1) and without diffusion gradient. B-factor was 500 sec/$\textrm{mm}^2$. Acquisition parameters are as follows: TUTE=10000ms/99ms, FOV=240mm, matrix=128${\times}$128, slice thickness/gap=6mm/0mm, total slice number=30. Subjects consisted of 10 normal young volunteers (age:21∼26 yrs, 5 men, 5 women). All DTI images were smoothed with Gaussian kernel with the FWHM of 2 pixels. Color coding schemes for visualization of directional information was as follows. HSV(Hue, Saturation, Value) color system is appropriate for assigning RGB(Red, Green, and Blue) value for every different directions because of its volumetric directional expression. Each of HSV are assigned due to (r,$\theta$,${\Phi}$) in spherical coordinate. HSV calculated by this way can be transformed into RGB color system by general HSV to RGB conversion formula. Symmetry schemes: It is natural to code the antipodal direction to be same color(antipodal symmetry). So even with no symmetry scheme, the antipodal symmetry must be included. With no symmetry scheme, we can assign every different colors for every different orientation.(H =${\Phi}$, S=2$\theta$/$\pi$, V=λw, where λw is anisotropy). But that may assign very discontinuous color even between adjacent yokels. On the other hand, Full symmetry or absolute value scheme includes symmetry for 180$^{\circ}$ rotation about xy-plane of color coordinate (rotational symmetry) and for both hemisphere (mirror symmetry). In absolute value scheme, each of RGB value can be expressed as follows. R=λw|Vx|, G=λw|Vy|, B=λw|Vz|, where (Vx, Vy, Vz) is eigenvector corresponding to the largest eigenvalue of diffusion tensor. With applying full symmetry or absolute value scheme, we can get more continuous color coding at the expense of coding same color for symmetric direction. For better visualization of fiber tract directions, Gamma and brightness correction had done. All of these implementations were done on the IDL 5.4 platform.

  • A kind of mineral water obtained from the basing of deep under the sea was reported to have a characteristic mineral composition and its effect on the quality of Kimchi was evaluated in this study. Kimchi samples were prepared with NaCl and the mineral water under rock floor as sources of salt together with fermented seafoods and fermented at 20 for 6 days. The qualities of Kimchi were evaluated by analyzing the pH, acidity, number of viable cell, lactic acid bacteria, sensory properties and texture profiles during fermentation. The pH and total acid contents were not different among Kimchi samples. The microbiological changes were not observed in the samples. The sensory scores of Kimchi containing NaCI and fermented sandlance sauce, and of Kimchi containing the mineral water under sea rock floor with fermented seafoods were significantly higher than those of the others. On the other hand, Kimchis prepared with NaCl alone or mineral water under sea rock floor alone earned the lowest sensory scores among the tested samples with an exception of firmness of the sample made with the mineral water. As the Kimchi fermentation proceeds, the hardness value of Kimchi prepared with the mineral water became higher than that of Kimchi with NaCl. This study suggests that the mineral water under sea rock floor could be useful to keep the texture of Kimchi firm during the fermentation.
