The objective of the present study was to investigate the effects of growth performance, chemical composition and meat quality parameters by the addition of fermented persimmon shell diets (FPSD). The experimental animals were ninety-six Berkshires. The pigs were allotted at 8 per pen in front-open building with three replicate pens per treatment. Until 61짹1 kg live weight at 140 days, the animals were fed growing diet, after which, experimental samples were fixed at 0, 3, 5 and 7% FPSD as C, T1, T2 and T3 in the finishing diets. Pigs of 103짹1 kg live weight were slaughtered by electrical stunning. In growth performance, ADG increased more (p<0.05) in T2 than C and T1. ADFI (kg/day) was higher (p<0.05) in T2 than in other groups. Feed conversion ratio was lower (p<0.05) in T2 than in other groups. On longissimus dorsi muscle (LM), the content of moisture was lower (p<0.05) in T3 than in other treatments. Crude fat increased (p<0.05) by addition of FPSD. pH at 24 h (pH24) decreased more (p<0.05) in T2 and T3 than C and T1 by addition of FPSD. WHC decreased (p<0.05) by addition of FPSD. In meat, Hunter L* and a* were lower (p<0.05) in C than in other treatments. Hunter b* was higher (p<0.05) in T3 than in other treatments. In back-fat, Hunter L* was higher (p<0.05) in C than in other treatments. Hunter a* was not different in C and T1 but increased (p<0.05) in treatments by addition of FPSD. Hunter b* increased (p<0.05) by addition of FPSD. In sensory evaluation scores, for fresh meat, the value of meat color was higher (p<0.05) in T2 and T3 than in C and T1. The value of marbling was lower (p<0.05) in C than in other treatments. The value of drip loss was higher (p<0.05) in C than in other treatments and was lower (p<0.05) in T2 and T3 than in other treatments. The results of cooked meat, the value of tenderness was not different in C and T1 but increased (p<0.05) in other treatments. The value of flavor was significantly higher (p<0.05) in T2 and T3 than in C and T1. The value of overall acceptability was increased (p<0.05) by addition of FPSD. Hence we can conclude that addition of FPSD affected growth performance and meat quality parameters, in particular, it improved crude fat, hunter L* and b*, and sensory evaluation on pork and was also seen to affect pH24 and WHC. FPSD can be used for improvement of meat quality parameters.

Background: Community-acquired pneumonia (CAP) is one of the leading causes of death among the elderly. Several studies have reported the clinical usefulness of serum procalcitonin, a biomarker of bacterial infection. However, the association between the levels of procalcitonin and the severity in the elderly with CAP has not yet been reported. The aim of this study was to evaluate usefulness of procalcitonin as a predictor of severity and mortality in the elderly with CAP. Methods: This study covers 155 CAP cases admitted to Pusan National University Hospital between January 2010 and December 2010. Patients were divided into two groups (≥65 years, n=99; <65 years, n=56) and were measured for procalcitonin, C-reactive protein (CRP), white blood cell, confusion, uremia, respiratory rate, blood pressure, 65 years or older (CURB-65) and pneumonia severity of index (PSI). Results: The levels of procalcitonin were significantly correlated with the CURB-65, PSI in totals. Especially stronger correlation was observed between the levels of procalcitonin and CURB-65 in the elderly (procalcitonin and CURB-65, ρ=0.408 with p<0.001; procalcitonin and PSI, ρ=0.293 with p=0.003; procalcitonin and mortality, ρ=0.229 with p=0.023). The correlation between the levels of CRP or WBC and CAP severity was low. The existing cut-off value of procalcitonin was correlated with mortality rate, however, it was not correlated with mortality within the elderly. Conclusion: The levels of procalcitonin are more useful than the levels of CRP or WBC to predict the severity of CAP. However, there was no association between the levels of procalcitonin and mortality in the elderly.

Objective: Accurate prediction of impending preterm birth in twin pregnancy is an important issue in the clinical decision for administration of antenatal corticosteroid or tocolytics and transfer to referral hospitals. Ultrasound cervical length(CL) measurement and fetal fibronectin(fFN) test is the most effective tools in predicting the risk of preterm delivery for asymptomatic twin pregnancies. The objective of this study was to evaluate the clinical value of fFN for prediction of preterm birth in symptomatic twin pregnancies. Methods: The study population consisted of twin pregnant women who had symptomatic preterm uterine contractions without evidences of ruptured membranes at <34 weeks. At the time of visit, fFN was tested. The clinical characteristics and the risk of preterm birth (< 7 and 14 days of visit and preterm delivery of < 34 and 37 weeks of gestation) was compared according to the result of fFN. Results: Between 2013 and 2018, total of 104 twin pregnant women visited our institution with preterm uterine contractions at <34 weeks of gestation. Among the study population, 50 women (48%) showed positive result for fFN. Positive fFN group had shorter cervical length and had higher risk for preterm birth (<7 days, <14 days, < 34 weeks, and <37weeks). The risk of preterm birth within 7 days of visit remained significant after adjustment for cervical length. Conclusion: In twin pregnant women with symptomatic uterine contractions, positive fFN may be used for prediction of preterm birth.

Kim, Min-Ji,Kim, Young-Hoi,Song, Geun-Sup,Suzuki, Yukio,Kim, Myung-Kon Japan Society for Bioscience, Biotechnology and Ag 2016 Bioscience, Biotechnology, and Biochemistry Vol.80 No.2

<P>Six -monoglucosyl derivatives of ginsenoside Rg1 (G-Rg1) were synthesized by transglycosylation reaction of rice seed -glucosidase in the reaction mixture containing maltose as a glucosyl donor and G-Rg1 as an acceptor. Their chemical structures were identified by spectroscopic analysis, and the effects of reaction time, pH, and glycosyl donors on transglycosylation reaction were investigated. The results showed that rice seed -glucosidase transfers -glucosyl group from maltose to G-Rg1 by forming either -1,3 (-nigerosyl)-, -1,4 (-maltosyl)-, or -1,6 (-isomaltosyl)-glucosidic linkages in -glucose moieties linked at the C6- and C20-position of protopanaxatriol (PPT)-type aglycone. The optimum pH range for the transglycosylation reaction was between 5.0 and 6.0. Rice seed -glucosidase acted on maltose, soluble starch, and PNP -D-glucopyranoside as glycosyl donors, but not on glucose, sucrose, or trehalose. These -monoglucosyl derivatives of G-Rg1 were easily hydrolyzed to G-Rg1 by rat small intestinal and liver -glucosidase in vitro.</P>

Kim, Ji Hoi,Kang, Hyun Sik,Han, Kyung Hee,Kim, Seung Hyo,Shin, Kyung-Sue,Lee, Mu Suk,Jeong, In Ho,Kim, Young Sil,Kang, Ki-Soo The Korean Society of Pediatric Gastroenterology 2014 Pediatric gastroenterology, hepatology & nutrition Vol.17 No.4

Purpose: With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. Methods: From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. Results: The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. Conclusion: Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.

2-D Synthesized Magnetic Field Focusing Technology With Loop Coils Distributed in a Rectangular Formation

Kim, Ji H.,Choi, Bo H.,Kim, Hoi R.,Rim, Chun T. Institute of Electrical and Electronics Engineers 2019 IEEE transactions on industrial electronics Vol.66 No.7

<P>In this paper, a novel loop coil structure for synthesized magnetic field focusing (SMF) technology and two current distribution calculating algorithms in the structure are proposed. The proposed structure enables field focusing in two-dimensional (2-D) space for the first time. The loop coil structure with a rectangular formation is adopted for a 2-D SMF system to minimize the volume and weight of the transmitting (Tx) coil array considering that conventional SMF systems inevitably have a volumetric design due to their dipole-based structure. Two algorithms to calculate the current distribution so as to focus the magnetic field at the target point are proposed. The first algorithm applies the Biot–Savart law to a loop-coil-based 2-D SMF system to calculate the distribution. The second algorithm utilizes a time-efficient synthesis method which reduces the matrix dimensions used in current distribution calculation. The second algorithm shows synthesis results with similar synthesis resolution compared with the first algorithm. Although the magnetic field distribution with the second algorithm has a little difference with that of first algorithm, its synthesis result focuses the magnetic field on the target point successfully, and it becomes more powerful as the number of coils increases. Synthesis results using two algorithms were compared with a finite-element method simulation with 100 Tx coils and 25 receiving (Rx) points. The synthesis resolution, as determined by –3 dB points, was enhanced by 4.45 times and 6.15 times for the first and the second algorithm, respectively, when compared to nonfocused case. An experimental prototype with 36 Tx coils and 9 Rx points with each coil 10 × 10 cm in size was built to demonstrate field focusing with current distributions calculated by the second algorithm at a frequency of 145 kHz. The experimental results were in good agreement with the simulated results, including a case in which the magnetic field was focused at Rx point other than center.</P>

Pre-transfusion Testing Using Crossmatching Agglutination Reaction Grades Combined With Rh Subgroup Phenotyping in Patients With Autoantibodies: A Three-year Experience at a Tertiary Hospital

Kim Jongmin,Shin Kyung-Hwa,Kim Hyerim,Kim Hyung-Hoi,Lee Hyun-Ji 대한진단검사의학회 2023 Annals of Laboratory Medicine Vol.43 No.5

Background: The currently recommended pre-transfusion testing techniques for patients with autoantibodies are complex, time-consuming, and labor-intensive. Therefore, although the red blood cell (RBC) selection method using crossmatched RBC agglutination reaction grades (i.e., the “least incompatible” transfusion) is discouraged, many institutions still use it. We aimed to evaluate the effectiveness of this method combined with Rh subgroup phenotyping. Methods: We retrospectively investigated RBC transfusions from January 2019 to December 2021 in patients presenting as auto-control-positive via antibody identification (auto-control (+) group), where Rh subgroup phenotype-matched RBCs were selected based on the agglutination reaction grades of crossmatched units. For each study patient, an auto-control-negative patient was matched based on age, sex, department, and pre-transfusion Hb levels (auto-control (−) group). The mean Hb change per unit, transfusion-associated symptom/sign reports, and agglutination reaction grades upon crossmatching were analyzed. Results: In the auto-control (+) group, the Hb change per unit among different agglutination reaction grades of transfused RBCs and among different relative grades of transfused RBCs and crossmatching auto-controls was not significantly different (P=0.392 and P= 0.132, respectively). No significant difference was observed in Hb changes and transfusion-associated symptom/sign occurrence between the auto-control (+) and auto-control (−) groups (P=0.121 and P=0.822, respectively). In addition, no definite evidence of hemolysis in the auto-control (+) group was observed in the medical record review. Conclusions: Together with Rh subgroup phenotyping, selecting the RBC unit with the lowest agglutination reaction grade upon crossmatching does not adversely affect transfusion efficiency.

An Ultra-low-power Mixed-mode Face Recognition Processor for Always-on User Authentication in Mobile Device

Ji-Hoon Kim,Changhyeon Kim,Kwantae Kim,Juhyoung Lee,Hoi-Jun Yoo,Joo-Young Kim 대한전자공학회 2020 Journal of semiconductor technology and science Vol.20 No.6

In this paper, we present an ultra-low-power analog-digital mixed-mode face recognition processor for user authentication in mobile devices. Unlike conventional face recognition processor architecture composed of an image sensor, high-resolution analog-to-digital converters (ADCs), and a digital signal processor, the proposed mixed-mode architecture removes the power-hungry ADCs and introduces an analog signal processor for processing the first layer of convolutional neural networks used by both face detection and face recognition as well as for performing ternary quantization. At the circuit level, we propose the reconfigurable readout circuit and exposure time-division scheme to integrate image sensor and analog signal processor without losing input data under various illumination conditions. We also propose the error-tolerant weighted-sum unit for analog convolution processing with only 15.09 uW power consumption. As a result, post-layout simulation results in 65 nm process demonstrate that the proposed mixed-mode face recognition processor has the total 0.205 mW power consumption while dissipating only 64 uW for always-on operation, which are 66.9% and 33.9% less than the state-of-the-art design.
