Objectives : This study aimed to investigate the psychosocial characteristics of functional gastrointestinal disorder (FGID) in patients with psychiatric disorders. Methods : This study was conducted with 144 outpatients visiting the psychiatric clinic at a university hospital. FGIDs were screened according to the Rome III questionnaire-Korean version. Demographic factors were investigated, and psychosocial factors were evaluated using the Hospital Anxiety Depression Scale, Patient Health Questionnaire-15, Childhood Trauma Questionnaire-Korean, and State-Trait Anger Expression Inventory. Chisquared test and student's t-test were used as statistical analysis methods. Results : There were differences in education level between two groups divided according to FGID status (${\chi}^2=10.139$, p=0.017). Comparing the psychiatric disorder by FGID group, irritable bowel syndrome (IBS) group showed significant differences (${\chi}^2=11.408$, p=0.022). According to FGID status, IBS group showed significant differences for anxiety (t=-3.106, p=0.002), depressive symptom (t=-2.105, p=0.037), somatic symptom (t=-3.565, p<0.001), trait anger (t=-3.683, p<0.001), anger-in (t=-2.463, p=0.015), and anger-out (t=-2.355, p=0.020). Functional dyspepsia group showed significant differences for anxiety (t=-4.893, p<0.001), depressive symptom (t=-3.459, p<0.001), somatic symptom (t=-7.906, p<0.001), trait-anger (t=-4.148, p<0.001), state-anger (t=-2.181, p=0.031), anger-in (t=-2.684, p=0.008), and anger-out (t=-3.005, p=0.003). Nonerosive reflux disease group showed significant differences for anxiety (t=-4.286, p<0.001), depressive symptom (t=-3.402, p<0.001), somatic symptom (t=-7.162, p<0.001), trait anger (t=-2.994, p=0.003), state anger (t=-2.259, p=0.025), anger-in (t=-2.772, p=0.006), and anger-out (t=-2.958, p=0.004). Conclusions : Patients with psychiatric disorders had a high prevalence of FGID, and various psychosocial factors contributed to such differences. Therefore, the psychiatric approach can offer better understandings and treatments to patients with FGID.

This study was conducted to determine the effect of pH adjustment on physico-chemical characteristics of chicken breast surimi. The chicken breast meat was ground with distilled water, of which pH was then adjusted to 2.5 (T1), 3.0 (T2), 10.5 (T3) and 11.0 (T4) for surimi manufacture, respectively. Water content was higher in order of T4>T1>T3>T2 (p<0.05). Crude protein and crude fat were higher in T3 and T4 compared with T1 and T2 (p<0.05). $L^*$ values, myofibrillar protein and water holding capacity of T2 and T4 were higher than those of T1 and T3 (p<0.05). T4 had the lowest yield among the treatments (p<0.05). T1 was higher in yield and pH, whereas breaking force and deformation were higher in T1 (p<0.05). $a^*$ was higher in order of T3>T2>T4>T1 and $b^*$ was lower in T1 compared with other treatments (p<0.05). In textural properties, the chewiness values of T2 and T3 were higher than those of T1 and T4, the hardness was higher in order of T2>T3>T4>T1 (p<0.05). Cohesiveness and gumminess of T1 showed higher values than those of other treatments (p<0.05). In sensory evaluation, the note for appearance was higher in T2 than other treatments (p<0.05), however other traits were not significantly different (p>0.05). Therefore, the alkaline processing (T4, pH 11.0) would be recommended.

A nitrogen (N) balance trial was conducted to examine the effect of N deprivation on subsequent N retention, blood urea nitrogen (BUN) and IGF-I levels and the ratio of IGF binding protein (IGFBP)-3 to IGFBP-l and -2. Pigs in treatment (T) 1 were given diet A (2.39% N) and those in T2 and T3 were given diet B (1.31% N) and excreta were collected (period 1 (P1)). Pigs in T1 continued to receive diet A while diets for T2 and T3 were changed to diets A and C (2.74% N), respectively. The excreta were collected for two more periods (P2 and P3). During P1, pigs in T2 and T3 retained 50% less N (p<0.001) than those in T1. However, pigs provided T2 (p<0.01) and T3 (p<0.05) retained more N than those assigned to T1 during P2. Pigs in T3 tended to retain more (p=0.10) N than those receiving T2 for the same period. The BUN values were lower (p<0.05) for pigs assigned to T2 and T3 than T1 during P1 and P2. Both IGF-I and IGFBP ratios of pigs assigned to T1 were higher (p<0.05) than those given T2 and T3 during P1 but no differences were found during P2 and P3.

The effect of Pleurotus eryngii and meat particle size on properties of sausage quality was investigated. Pleurotus eryngii and meat were processed and combined in the following three ways: T1 (minced Pleurotus eryngii+emulsified meat), T2 (chopped Pleurotus eryngii+emulsified meat) and T3 (chopped Pleurotus eryngii+chopped meat). The pH values of sausages showed T1 to be significantly higher (p<0.05) than T2 and T3. The shear force values showed no significant difference between treatments. T2 and T3 had significantly higher hardness values (p<0.05) than T1. With regard to color, the lightness and whiteness of sausage were significantly higher (p<0.05) for T1 and T2 than for T3. No significant differences between treatments were found regarding redness and yellowness. Panels rated T2 and T3 significantly higher (p<0.05) for aroma and flavor than T1. T2 was rated significantly juicier (p<0.05) than T1, T2 and T3 were rated significantly higher (p<0.05) for overall acceptability than T1.

Muscle mass is reduced by aging. There seems to be no direct relationship between sarcopenia(muscle loss) and medical cost in the elderly, but lowering muscle mass results in increase risk of fall and decrease of strength, fitness, physical activity, and independent life. This is coupled with physical trouble and chronic degenerative disease such as diabetes, obesity, hyperlipidemia, and hypertension. Thus, sarcopenia is potential risk factor increasing mortality. The purpose of this study was to investigate the effects of elastic band exercise and detraining on sarcopenia prevention related variables, body composition and fitness. The subject of this study was 60~70 aged 14 seniors who participated in exercise program in J-welfare senior center at J-gu in S-city. Elastic band exercise was performed twice per week for 12 weeks. The body composition and fitness variables were measured before 12 weeks of control, after control(before exercise), after 12 weeks of exercise(before detraining), and after 12 weeks of detraining. There was no significant difference in body composition and fitness variables before and after 12 weeks of control, but elastic band exercise before and after 12 weeks has effect on body composition variables such as weight (t=2.978, p=0.001), body mass index (t=3.502, p=0.004), percent body fat (t=2.216, p=0.045), muscle mass (t=-3.837, p=0.002), visceral fat area (t=5.186, p<0.001), and waist-hip ratio (t=3.045, p=0.009) and on fitness variables such as 2-minutes step (t=-6.891 p<0.001), arm curl (t=-4.702, p<0.001), chair stand (t=-4.860, p<0.001), chair sit and reach (t=-5.910, p<0.001), back scratch (t=-3.835, p=0.002), and 8-ft up and go (t=7.560, p<0.001). This exercise effect was continued after 12 weeks of detraining on body composition variables such as weight (t=2.323, p=0.037), body mass index (t=2.503, p=0.026), muscle mass (t=-3.137, p=0.008) and on fitness variables such as 2-minutes step (t=-6.489 p<0.001), chair stand (t=-4.694, p<0.001), chair sit and reach (t=-3.690, p=0.003), and 8-ft up and go (t=7.539, p<0.001). It was found that the elastic band exercise has positive effect on body composition and fitness in the elderly and the effect was maintained over 12 weeks of detraining.

Semiempirical MNDO calculations are employed to study ionicity of OH groups and stability in $T_1-OH-T_2bridges(T_1$ = Al, B and $T_2$ = P, Si) such as found in aluminophosphate family($AlPO_4-5$, BAPO-5, and SAPO-5) molecular sieves. Dimeric model clusters of Al-OH-P, B-OH-P and Al-OH-Si bridges were considered. It is shown that the elongation of the T-O bond, upon replacement of Al by B, occurs preferentially by a local deformation of the Al-O-P bridge. But the elongation of the T-O bond occurs preferentially by a rotation of Al-O-Si bridge upon substitution P for Si. Also, the ionicity of OH groups and stability increase in order to B-OH-P < Al-OH-P < Al-OH-Si bridge.

This study was carried out to investigate the effects of the seeding dates and growth periods on the growth characteristics, dry matter yield and feed value of corn for silage in paddy field. The experimental design was arranged in a randomized block design with three replications. Treatments consisted of five seeding dates, 1 May (T1), 8 May (T2), 15 May (T3), 22 May (T4) and 29 May (T5). And harvesting time homologized by August 24. Therefore, growing periods were 115 days (T1), 108 days (T2), 101 days (T3), 94 days (T4) and 87 days (T5), respectively. In maturities at harvest time, T1, T2, T3, T4 and T5 were full dent, early dent, late dough, dough and early dough stage, respectively. Plant height and numbers of root system were highest in T5 (p<0.01), but leaf length was higher in T4 than others (p<0.05). Dead leaf, tip filling degree and ear circle were higher in T1 than others (p<0.05, 0.01). Leaf width, ear height, leaf number, ear length, stem diameter, stem hardness and brix were not significantly different among the treatments. Dry matter yield and TDN yield were higher in the order of T1 > T2 > T3 > T4 > T5 (p<0.01). Crude protein, crude ash, NDF, ADF and crude fiber were significantly higher in T4 (p<0.05, 0.01). But crude fat was the highest in T1, T3 was the lowest as compared to other treatments (p<0.01). Total EAA(essential amino acids) were higher in order of T4 > T3 > T1 > T2 > T5, and total NEAA (nonessential amino acids) were higher in order of T1 > T4 > T2 > T3 > T5, and total amino acids were higher in order of T4 > T1 > T3 > T2 > T5. But no significant differences were found among the treatments. TUFA (total unsaturated fatty acid) and TSFA (total saturated fatty acid) were in order of T1 > T2 > T3 > T5 > T4 (p<0.01). Minerals were the highest in T4 (4,721.25 mg/kg), and T2 (2,970.80 mg/kg) was the lowest as compared to other treatments (p<0.05). Based on the above results, seeding dates could be recommended as early May, and harvest times is yellow ripe stage for qualitative and quantitative production of corn for silage in rice paddy field soil.

This study was carried out to investigate the effects of seeding dates and cultivated period on the growth characteristics, dry matter yield and feed value of Teosinte new variety "Geukdong 6"[Zea mays L. subsp. mexicana (Schrad.) H. H. Iltis]for feed. The experimental design was arranged in a randomized block design with three replications. Treatments consisted of five time seeding dates, 10 May(T1), 25 May(T2), 10 June(T3), 25 June(T4) and 10 July(T5), and same time harvesting, 22 October. Therefore, growing period were 164 days(T1), 149 days(T2), 134 days(T3), 119 days(T4) and 103 days(T5), respectively. In growth stage at harvest time, T1, T2, T3, T4 and T5 were early flowering, end heading, middle heading, early heading and early heading stage, respectively. Plant length and dead leaf were highest in T1, but leaf width and number of leaf were highest in T2 than others (p<0.05). Leaf length, stem diameter and number of tiller were not significantly different among the treatments (p<0.05). Stem hardness was higher in order of T1(2.0)> T2(1.9) > T3=T4(1.7) > T5($1.2kg/cm^2$). Fresh yield and dry matter yield showed significantly higher as the sowing time was faster and the cultivation period was longer (T1 > T2 > T3 > T4 > T5, p<0.05). Crude protein, crude fat and TDN content were highest in T5, but ADF and NDF content were highest in T1 than others (p<0.05). T1, T2 and T3 showed significantly higher crude protein yield compared to T4 and T5 (p<0.05). Total digestible nutrients yield were higher in order of T1 > T2 > T3 > T4 > T5 (p<0.05), and relative feed value were higher in order of T5 > T4 > T3 > T2 > T1 (p<0.05). Based on the above results, seeding dates could be recommended from the early May to the late May, and it is efficient that the cultivation period is over 150 days for dry matter yield, crude protein yield and total digestible nutrients yield.
