Purpose: The objective of this study was to examine the correlation between HbA1C, self-care behavior, and quality of life among depressed and non-depressed patients with type II diabetes Methods: Data were collected between May 26 and July 5, 2011 using a questionnaire. The questionnaire included depression (CES-D), self-care behavior and quality of life. Hemoglobin A1C was ed from medical records. Data were analyzed by descriptive statistics, t-test, $x^2$-test, ANCOVA and Pearson's correlation coefficient. Results: In this study sample (n=301), 20.9% of diabetic patients (n=69) were depressed. After adjustment for relevant covariates, depressed patients showed to have lower self-care behavior (2.8 vs 3.4, p<.001) and quality of life (2.8 vs 3.5, p<.001) scores, but the difference in HbA1C was no longer significant. Conclusion: This study suggests that the assessment and intervention for depressed diabetic patients can result in effective self-care behavior, which accordingly leads to improvement of the quality of life.

We present the near-infrared spectra (2.5-5.0 um) of shocked $H_2$ gas, observed with the Infrared Camera onboard the satellite AKARI. Two supernova remnants, IC 443 and HB 21, were observed. IC 443 shows a hint of non-equilibrium ortho-to-para ratio (OPR): 2.4 (-0.2, +0.3). HB 21 also shows an indication of a potential non-equilibrium OPR: 1.8-2.0. These non-equilibrium OPRs are first reported for shocked $H_2$ gas at E(v,J) > 7000 K, as far as we are aware. We concluded that the non-equilibrium OPR probably originates from dissociative J-shocks, considering several factors such as the shock combination requirement, the line ratios, and the possibility that $H_2$ gas can form on grains with a non-equilibrium OPR. The difference in the collision energy of H atoms on grain surfaces would give rise to the observed difference between the OPRs of IC 443 and HB 21, if dissociative J-shocks are responsible for the $H_2$ emission. Our study suggests that shocked-then-cooled $H_2$ gas may play as a heat reservoir with the non-equilibrium OPR.

This paper proposes a control methodology for a high efficiency operation of an inductive power transfer (IPT) converter by combining full bridge (FB) and half bridge (HB) controls. To apply the proposed control to the IPT converter, the characteristics of each control method are analyzed. By examining the output voltages of the IPT converter and a theoretical loss analysis, the control shifting points between FB and HB controls are evaluated in accordance with the coupling coefficients and the load. Based on the control shifting points, the FB-HB control algorithm is implemented. By applying FB-HB control, high efficiency operation at the light load condition can be achieved.

Purpose: This research seeks to identify differences between general characteristics, disease-related characteristics, glycated hemoglobin (HbAlc) levels, and aspects of chronic complications of diabetes mellitus in type 2 diabetes. Methods: This research was conducted from the 1st to the 15th of February in 2016, on 263 in patients. Patients' electronic medical records were used to identify their general characteristics, disease-related characteristics, HbAlc, and chronic diabetic complications. Chi-square test, ANOVA, ANCOVA, and the Cochran-Mantel-Haenszel test were used for data analysis. Results: Statistical significance was observed for general characteristics, based on smoking status, such as age, and education level; disease-related characteristics differed according to the duration of diabetes. Smoking status did not differ according to HbAlc level. In term of chronic diabetic complications, statistically significance was observed for diabetic nephropathy, based on smoking status. Conclusion: Patients who had a history of smoking, but were not currently smoking, were likely to display higher HbAlc levels and diabetic nephropathy. Therefore, there is need for regular checkups for diabetic complications among patients with a history of smoking and it is important to emphasize smoking cessation.

This study mainly investigated the improvement effect of nitroso-hemoglobin (NO-Hb) and four lactic acid bacteria (LAB) (Streptococcus thermophiles, Lactobacillus bulgaricus, Lactobacillus casei, and Montessori enterococcus) on the color and microbiological qualities of raw beef. Three strains of Escherichia coli, Staphylococcus, Salmonella, and Pseudomonas were used as pathogenic bacteria. The results showed that both NO-Hb and LAB could enhance the color stability and scavenged the spoilage bacteria in a minced beef model. But the improvement effect of NO-Hb was more significant than LAB. This suggested that NO-Hb, as a novel ingredient, could be used as a promising substitute for nitrite in meat products to improve the color and safety of meat products. In addition, low field (LF)-NMR method has been established to be practicable to identify changes in the relaxation times of water and fat caused by different type of bacteria and the storage periods. The number of relaxation components in minced beef was affected by bacteria and increase of the storage period.

Two patients with sequelae of peripheral facial nerve palsy were treated with Facial Chuna Manual Therapy (FCMT) and acupuncture over 6 months. The House-Brackmann (HB) scale, facial nerve grading system 2.0 (FNGS), the scale of Peitersen, the scale of Murata, and the Numeric Rating Scale (NRS) were used to assess the effects of treatment. The HB scale, FNGS and NRS scores showed improvement for both patients (Case 1: HB scale 5 to 3, FNGS 4 to 2, NRS 10 to 5; Case 2: HB scale 5 to 3, FNGS 4 to 3, NRS 10 to 2.5) following 6 months of treatment. The scores for the Peitersen and Murata scales showed improvement over 6 months in Case 1 (Peitersen 2 to 1, Murata 10 to 7), but there was no change in Case 2 over the test period (4 months). FCMT and acupuncture may help patients with sequelae of facial palsy.

The polyesters (polyhydroxyalkanoates; PHAs) production capability in a two-step cultivation of Alcaligenes eutrophus H16(ATCC 17699) was investigated by using various organic carbon sources. The carbon sources used included linear $C_2~C_10$ monocarboxylic acids, $C_3~C_10$ dicarboxylic acids, crotonic acid, and several linear vicinal and $\omega$-diols. The polyesters synthesized were characterized by 500 MHz $^1 H-NMR$ spectroscopy, intrinsic viscosity$[\eta]$ measurement in chloroform and differential scanning calorimetry (DSC). The PHAs synthesis data showed that the use of C-odd ($C_3, C_5, and C_7$) monocarboxylic acids resulted in poly(3-hydroxybutyrate-co-3-hydroxyvalerate)(P(3HB-co-3HV) (3HV content ranging 40 to 70 mol%) while the use of $C_9$ substrate gave the copolyester containing only 4 mol% of 3HV. All culture products obtained on $C_3$~C$_{10}$ dicarboxylic acids gave exclusively P(3HB). 500 MHz $^1 H-NMR$ analysis showed that all polyesters synthesized generally contained 1~2 mol% 3HV even for the unrelated substrates such as the carboxylic acids with even number of carbon. When $\alpha, \omega$-diols with even number of carbon were used as substrates, 4-hydroxybutyrate(4HB) was inserted into the polyester chain composed of P(3HB-co-4HB). Vicinal diols were generally not utilized by the bacterium for polyester production.n.

The aim of this paper was to estimate genetic parameters for body weight and five body measurements for an experimental population of Iranian Makooei sheep maintained at the Makooei Sheep Breeding Station at Makoo, Iran. To do this, yearling live weight (YW), and five body measurements, i.e., body length (BL), heart girth (HG), height at withers (HW), height at back (HB) and scrotal circumference (SC), were analyzed in a multi-trait animal model using the DXMUX program of DFREML software package. Heritability estimates were $0.22{\pm}0.08$, $0.11{\pm}0.06$, $0.21{\pm}0.07$, $0.17{\pm}0.06$, $0.17{\pm}0.06$ and $0.32{\pm}0.10$ for YW, BL, HG, HW, HB and SC, respectively. These estimates indicate that selection in Makooei sheep would generate moderate genetic progress in body weight and body measurements. Scrotal circumference, as an indicator of reproductive potential, exhibited the highest heritability. This trait, therefore, could successfully be used to increase productivity of males and, indirectly, female fertility. Genetic correlations between traits studied were all positive and ranged from 0.15 (YW/HB) to 0.99 (HW/HB). Phenotypic correlations were also positive and ranged from moderate (0.32, HW/SC) to high (0.94, HW/HB). Positive genetic and phenotypic correlations indicate that improvement in body measurements both at the genetic and phenotypic levels is expected through selection on body weight and vice versa.

Objective: The objective of the present study was to compare growth performance of Berkshire purebred pigs (BB), Hereford (HB) and/or Tamworth (TB) sired Berkshire crossbred pigs reared in a hoop structure in two experiments. Methods: In the first experiment, BB was compared to TB while HB and TB were compared in the second. Body weights (BW) were recorded at 3 days of age and every 28 days from birth until 140 days of age. There was no significant difference between the BW of BB and TB, but HB was heavier than TB by 84 days of age. Least square means of average daily gain (ADG) were evaluated using one-way analysis of variance. Results: The mean parity (${\pm}$standard deviation) of the sows was $3.42{\pm}2.14$ and a total of 45 farrowing occurred from year 2012 to 2014. The mean number of total born, number born alive, number of mummies, and number weaned were $9.23{\pm}2.52$, $7.87{\pm}2.53$, $0.04{\pm}0.21$, and $5.94{\pm}2.74$, respectively. Parity did not have a significant effect on the growth performance of the pigs. For BB and TB, there was only one time frame in which there was a significant difference in the ADG: between 28 and 56 days of age. For HB and TB, the overall ADG of HB was significantly greater than the total ADG of TB. Conclusion: The breed of the sire did not affect the growth performance of the progeny between Berkshire purebreds and Tamworth${\times}$Berkshire crossbreds. The breed of the sire did have an effect between Hereford and Tamworth sired Berkshire crossbreds (p<0.05). The Hereford sired pigs were found to have increased growth performance compared to Tamworth sired.

OTP(One time password) is widely used as an authentication method for financial and other security-sensitive transactions. OTP provides strong security since each password is used only one time while normal password-based authentications use passwords as long term secrets. However, OTP-based authentications relatively lack usability since they require users to hold an OTP card or generator. To overcome such a problem, smartphones start replacing OTP cards and such a method is called smart OTP. However, smart OTP inherits security vulnerabilities that smartphones have. In this paper, we propose a smart OTP authentication based on an extremely light authentication protocol called HB+. HB+ protocol is developed for low-cost devices and has small communication and computation costs. We present our solution and discuss its security, efficiency and practicality. Our contribution is providing a method to securely use smart OTP without losing its efficiency and usability.
