  • This study was conducted to investigate the influence of dietary mugwort (0, 1, 2, 4%) and sardline oil(1%) on weight gain, pH, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), and meat color in meat-type chickens. Birds were randomly assigned to the four dietary treatments: control (commercial feed), control plus 1% mugwort and sardine oil (T1), 2% mugwort and 1% sardine oil(T2), or 4% mugwort and 1% sardine oil (T3). Birds were sacrificed and meat samples were taken and stored for either 0, 3, 7 or 10 days at $4^{\circ}C$. Weight gain in T3 was lowest than other treatment groups (P<0.05). pH of dietary mugwort and sardine oil treatments increased significantly compared to that of control during storage periods (P<0.05). VBN and TBARS of all treatment groups were significantly increased as storage period extended (P<0.05). Meat color $(L^*,\;b^*)$ significantly increased during storage periods. $L^*\;and\;b^*$ values were higher in treatment groups than in control (P<0.05). These results indicate that the mugwort and fish oil may improve quality and self-life of meat-type chickens during storage.

  • Speech intelligibility in patients with complete dentures is an important clinical problem depending on the material used. The objective of this study was to investigate the speech of two edentulous subjects fitted with a complete maxillary prosthesis made of two different palatal materials: chrome-cobalt alloy and acrylic resin. Three patients with complete dentures in the experiment group and ten people in the controls groups participated in the experiment. CSL, Visi-Pitch were used to measure speech characteristics. The test words consisted of a simple vowel /e/, meaningless three syllabic words containing fricative, affricated and stops sounds, and sustained fricative sounds /s/ and /$\int$/. The analysis speech parameters were vowel and lateral formants, VOT, sound durations, sound pressure level and fricative frequency. Data analysis was conducted by a series of paired T-test. The findings like the following: (1) Vowel formant one of patients with complete denture is higher than that of the control group (p<0.05), while lateral formant three of patients with complete denture is lower than that of the control group (p<0.0l). (2) Patients with complete denture produced lower speech intelligibility with low fricative frequency (/$\int$/) than control group (p<0.0). The speech intelligibility of patients with metal prosthesis was higher than that of those with resin prosthesis (p<0.05). (3) Fricative, lateral and stop sound durations of patients with complete denture were longer than those of the control group (p<0.01 and p<0.05), respectively. Total sound durations of patients with metal prosthesis were similar to that of the control group (p<0.05), while those with resin prosthesis had a shorter duration (p<0.01). This implied that those with metal prosthesis had higher speech intelligibility than those with resin prosthesis. (4) Patients with complete denture had higher sound pressure levels /t/ and /c/ than the control group (p<0.01). However, sound pressure levels for /c/ of patients with metal prosthesis or resin prosthesis was similar to the control group (p<0.05). (5) Patients with complete denture had higher fundamental frequency than the control group (p<0.01).

  • The purpose of this study is to evaluate the nutrient intake and selected blood parameters of adults with metabolic syndrome (MS) and to provide data in forming a dietary guideline for the prevention of chronic diseases. Subjects were recruited and divided into two groups according to the NCEP-ATP III criteria and WHO Asia-Pacific Area criteria for obesity. MS group was defined as subjects who have three or more risk factors and control group was defined as those with two or less of the risk factors. The average age, height, weight, body mass index (BMI) were 58.8 years, 158.0 cm, 66.3 kg, $26.5\;kg/m^{2}$, respectively, in the MS group; and 58.4 years, 158.9 cm, 59.6 kg, $23.5\;kg/m^{2}$, respectively, in the control group. The weight and BMI in the MS group were significantly higher than those in the control (p<0.001). There was no significant difference in the food and nutrient intake between the MS and control group. Male subjects in the MS group showed significantly higher intake of mushrooms than those in the control (p<0.05). Egg consumption in the MS group was significantly lower than those in the control (p<0.01). Consumption of vegetables and fiber was significantly lower for female subjects in the MS group than those in the control (p<0.05). Serum GPT, AI and WBC count in the MS group (27.8 IU/L, 3.7, $5964.2\;{\mu}/L$) were significantly higher than those in the control (22.6 IU/L, 3.2, $5250.0\;{\mu}/L$; p<0.01, p<0.001, p<0.01). In conclusion, consuming fiber and vegetables may prevent and reduce metabolic syndrome in adult men and women, and this study demonstrates the need for proper dietary management for them.

  • A two parameter model of a single fictitious weak acid with unknown dissociation constant has been successfully applied to design a neutralization system for many multi-component acid streams. But there are some processes for which above two parameter model is not satisfactory due to poor approxmation of the nonlinearity of pH process. Here, for etter control of wide class of multi-component acid streams, a three parameter model of a strong acid and a weak acid with unknown dissociation constant is proposed. The model approximates effectively three types of largest gain variation nonlinearities. Based on this model a nonlinear pH control system is designed. Parameters can eeasily estimated since their combinations appear linearly in the model equations and nonlinear adaptive control system may also be constructed just as with the two parameter model.

  • Objectives : This research was conducted to determine the effect of the Visiting Oral Health Care Program by examining the oral health of the elderly women, who are the beneficiaries of this Visiting Oral Care Program. Methods : This research was conducted from November of 2011 to February of 2012, in Chilgok-gun in the Kyeongbuk Province, South Korea. One hundred and twenty five (125) elderly women among the beneficiaries of the Visiting Oral Care Program within the area were randomly selected for the research. The research subjects would regularly visit the area senior citizen center, and they were divided into two groups, with 64 of them belonging to a control group, and the rest (61 people) belonged to a intervention group. The research subjects were examined for their dental health condition, and we investigated the effect of the Visiting Oral Care Program through this research. Results : 1. When they were asked about how many times they wash their dentures, the majority of the control group, 57.4% of them answered that they do it "once" a day. The majority of the intervention group answered "more than 3 times", with 35.2% of group mentioning that they wash their dentures more than 3 times a day(p<.001). 2. When the research subjects were asked to scale their overall quality of life before and after the Visiting Oral Care Program, the control group had rated 49.3 before the Service and 56.8 after the Service (p<.01), and scores for the individual factors to determine the overall quality of life has significantly improved as well (p<.01, p<.01, p<.01, p<.01, p<.01, p<.01, p<.01). 3. The oral hygiene condition after the Visiting Oral Care Program has shown improvement as well. The control group scored 64.2 for the severity of the symptoms of dental plaque before the dental care, and scored 46.8 after the dental care (p<0.1). The control group was diagnosed for the symptoms of coated tongue, and the severity of the symptoms were scaled as 3.7 before the Program and 2.0 after the Program (p<.01). Furthermore, the overall functionality of the oral cavity was improved as well. The control group showed 1.0 time increase in repetitive voluntary swallowing test (p<0.1), increased amount of sublingual saliva from 0.8mm to 1.4mm, and from 1.6mm to 2.0mm in dorsum linguae(p<0.1). Also, the control group showed an improvement in mouth opening as well, increased from 3.9 to 4.0cm after the oral care program (p<.05). When compared the result with the examination after the Visiting Oral Care Program, the two groups showed a significant difference with the control group showing a significant improvement compared to the intervention group(p<.01, p<.01, p<.01, p<.01, p<.05). 4. The correlation between the dental hygiene condition and the functionality of oral was made for the result of examining the beneficiaries for Visiting Oral Care Program. The amount of saliva showed a negative correlation with the severity of dental plaque (p<.05), and a positive correlation with the repetitive voluntary swallowing count (p<0.1). Also, mouth opening showed a positive correlation with repetitive voluntary swallowing count (p<.05). Conclusions : After the Visiting Orall Care Program, the beneficiaries of the program experienced improvement in their quality of life related to oral health, overall oral hygiene and functionality of oral.

  • Two experiments were conducted to compare the effects of feeding organic acids and antibiotic growth promoters in weaned pigs. In Exp. 1, 96 nursery pigs (Large White$\times$Landrace; initial weight $7.80{\pm}0.07kg$) were randomly allotted into one of four dietary treatments. Pigs in treatment 1 were fed a complex starter diet. Treatments 2 to 4 were the same as treatment 1 but supplemented with antibiotics (200 ppm chlortetracycline plus 60 ppm Lincospectin), 0.5% potassium diformate or 0.5% dry organic acid blend ACTIVATE Starter DA (ASD). During the 4-week post-weaning period, pigs fed ASD or antibiotics had better gain (p = 0.03) and feed efficiency (p = 0.04) than pigs fed the control diet. On d 14 post-weaning, pigs fed the control diet had the lowest fecal lactobacilli count among all dietary treatments (p = 0.02), whereas pigs fed ASD or antibiotics had a trend for lower fecal E. coli count compared to the control pigs (p = 0.08). Serum insulin-like growth factor-1 (IGF-1) of pigs fed ASD did not differ from pigs fed the control diet (p>0.05) at d 14 after weaning. In Exp. 2, 24 weaned pigs (Large White$\times$Long White; initial weight $5.94{\pm}0.33kg$) were allotted into four groups and housed individually. Pigs were fed a control diet or diets supplemented with antibiotics (100 ppm colistin sulfate, 50 ppm Kitasamycin plus 60 ppm Olaquindox), 0.5% or 1% ASD. All pigs were orally challenged with E. coli $K88^+$ on d 5. During d 5 to 14 after challenge, pigs fed antibiotics, 0.5% or 1% ASD had better gain (p = 0.01) and feed efficiency (p = 0.03) than pigs fed the control diet. On d 14, compared to the control pigs, pigs fed 0.5% ASD had higher lactobacilli in the duodenum and pigs fed 1% ASD and antibiotics had a trend for higher lactobacilli in the ileum (p = 0.08). Pigs fed antibiotics, 0.5% or 1% ASD diets tended to have decreased ileal E. coli count compared to those fed the control diet (p = 0.08). Serum interleukin-6 and cortisol and digesta pH values were not affected by treatment or time. These results indicate that feeding ASD can improve the growth performance of weaning pigs, mainly via modulating intestinal microflora populations without affecting gastrointestinal pH or immune indices.

  • The purpose of this study was to identify the degree of self-efficacy, sick-role behavior and metabolic control in patients with diabetes and to identify the relationships among those variables. The subject of the study were composed of 204 NIDDM patients from 2 hospitals, who were visiting the outpatient clinic in Taegu. Data were collected from Sep. 18th to Oct. 5th, 1996. In data analysis, an SPSS/PC+ program was utilized for descriptives correlation, T-test, and ANOVA. The results are as follows. 1) The mean scores for self-efficacy were 65.74 (range 30.83-90.68), on a 100 point scale. 2) The mean scores for sick-role behavior were 3.36(range 1.80-4.67), on a 5 point scale. 3) The mean score for metabolic control was 7.63 (range 5.0-13.2). 4) Self-efficacy was significantly correlated with sick-role behavior(r=.3614, p<0.01) but there were no significant correlations with self-efficacy and metabolic control (r=-.1045, p>0.01), sick-role behavior and metabolic control (r= - .1288, p>0.01). 5) There were significant differences in self-efficacy according to sex(t=4.47, p=0.000) and education(F=8.27, p=0.000). 6) There were no significant differences in sick -role behavior according to demographic characteristics. 7) There were significant differences in metabolic control according to the duration of diagnosed diabetess(F=4.13, p=0.007) and complication (t=2.47, p=0.014). These results suggest that for improvement in sick-role behavior nursing intervention needs to be directed at promoting self-efficacy.
