Sulgidduk samples containing 1, 2, and 4% Adenophora remotiflora powder and a control were examined for moisture content, gelatinization property, color, textural characteristics, and sensory qualities to determine the optimal ratio of Adenophora remotiflora powder in the formulation. The highest viscosity, lowest viscosity, final viscosity, setback and breakdown decreased as the contents of Adenophora remotiflora powder increased in the gelatinization property of flour blends of rice cake made with Adenophora remotiflora powder. The water content of rice cake with Adenophora remotiflora powder was 40.54~41.30% and there was no significant difference between samples with Adenophora remotiflora powder. L values indicating brightness were highest in the control group and all of the a values displayed green color indicating that they were negative. The b values were lowest in the control group and the values increased as the level of Adenophora remotiflora powder increased. Evaluation of the mechanical characteristics of rice cake with Adenophora remotiflora powder, hardness, cohesion, adhesion and chewiness were all higher in the control group and as its contents were rich, such properties were reduced. In addition, there was no significant difference between adhesion and chewiness. Adhesion and elasticity were low in the control group and as its contents were rich, such properties increased. The results of the sensory test revealed that the, control group containing 1% Adenophora remotiflora powder had the highest color, flavor, taste and overall preference.

The purpose of this study was to evaluate shear parameters on cutting slope of weathered granite soils by using small dynamic cone penetration test on the very moment of its cutting. The results were : On the relations among N$\_$c/, Li, and CEC, the condition of Li＞6%, CEC＞14(meq/100g) corresponds to that of N$\_$c/ values of 2∼30, and 3＜CEC＜14(meq/100g) to N$\_$c/=30∼50. Comparing the smallest penetration depth from two small dynamic cone penetration tests done at 5m below from the top of the slope on April 15th, October 31t. there was a l0cm difference. So we could find out the degree of weathering on the slope. And dividing the difference by 190 days (the whole testing time), we could know it's being weathered 0.052mm each day. The more N. value increases, the more shear parameters(internal friction angle ; $\phi$, cohesion : c) increase at a standard pressure($\sigma$＞32㎪). So the condition of N$\_$c/=2∼50 corresponds to that of $\phi$=27∼50, c=12∼49㎪. From the above testing results, the N$\_$c/ values more correspond to $\phi$ values than c values. In conclusion, this study suggests that on small dynamic cone penetration test a penetration boundary line of 5 centimeters is decided at around Li=4%, CEC=3(meq/100g) which is classified as a strong weathering soil. It also shows that as Li increases CEC increases as well, while N$\_$c/ decreases.

Purpose: The objective of this study was to compare initial implant stability measured by RFA between different implant systems during the initial healing period. Material and Methods: Fifty-four patients (36 males/18 females) who had been treated at the Department of Periodontology, Chonbuk National University Dental Hospital during the period between January and November in 2007 were included in the study. The mean age of the subjects was 49 years old (18 to 77). A total of 104 implants (Type A: 3i $Osseotite^{(R)}$, Type B: $Replace^{(R)}$ select, Type C: ITI implant) were placed following the manufacturer's standard surgical protocols. Implant stability quotient (ISQ) readings were obtained for each implant at the time of surgery, 2-, and 4-month postoperatively. Result: No implant was failed during the observation period. At the baseline, the difference between mean ISQ values of 3 implant systems was statistically significant (p<0.05). However, at 2-, and 4-month following implant surgery, no significant difference was observed between ISQ values of the implant systems. In the same implant, the ISQ values of Type B and C implants increased (p<0.05), but those of Type A implants decreased during the 2-month healing period. The mean ISQ values of Type B and C implants showed a increasing tendency, while those of Type A implants were stable for the 4-month follow-up period. Conclusion: Within limits of this study, it can be concluded that implant design and surface topography of implant might influence the ISQ value and changing pattern during the initial healing period.

The purpose of this study is to assess the effect of progressive muscle relaxation therapy on nausea, vomiting and anxiety experienced by children who were histologically diagnosed as malignancy and have received cancer chemotherapy. Twenty subjects with 10 in experimental group and 10 in control group, between the age of 7 to 12 years participated in this study. All subjects were admitted for inpatients chemotherapy at the S hospital between April to August 1998. The methods used for interventional muscle relaxation were both the 16 items of the progressive muscle relaxation therapy developed by Jacobson and the 4 items of the muscle relaxation therapy by Wolpe. The method for assessing nausea, vomiting was the Index of Nausea and Vomiting by Rhodes et al and that for anxiety was State-Trait Anxiety Inventory for Children by Spielberger. The data was analysed by repeated measures ANOVA and Scheffe test using SAS program. The results were as follows : 1. On measurement of nausea, vomiting, in the experimental group, the mean values of the second and the third measurements showed tendency to slightly decrease compared with the first measurement, but there was no statistically significance. And in the control group, there were no significant differences among first measurement, second measurement and third measurement. Also there was no significant difference in the mean values assessing nausea, vomiting between experimental and control group (F=1.33, p=0.2645). 2. The results assessing state anxiety showed, in the experimental group, progressive decrease in mean values at each measurement, while the control group showed no significant differences between the mean values of each measurement. Also there was statistically significant difference in state anxiety measurements between experimental and control group(F=4.36, p=0.05). In conclusion, muscle relaxation therapy for school-aged children with chemotherapy could not be effective to decrease nausea, vomiting, but it could be effective to decrease anxiety.

Purpose: Previous studies have reported the difference in nutritional status between South and North Korean infants and young children (IYC). Clear understanding on the nature of such differences is essential for planning food and nutrition policies and programs to prepare for a possible re-unification of the two Koreas in future. This study was undertaken to yield valid statistics comparing the nutritional status between North and South Korean IYC. Methods: Raw data obtained from the 2017 Korean National Growth Chart and the 2013-2017 Korea National Health and Nutrition Examination Survey were analyzed to determine the comparable statistics that include weight for age z-score (WAZ), height for age z-score (HAZ) and weight for height z-score (WHZ), with data reported in the Survey Findings Report of the 2017 DRP Korea Multiple Indicator Cluster Survey. The average weight and height by gender and month were estimated for North Korean IYC and calculated for South Korean IYC. SPSS analysis was applied to evaluate the acquired statistics and compare the nutritional status of South and North Korean IYC. Results: WAZ, HAZ and WHZ of North Korean IYC were observed to be lower than values obtained for South Korean IYC as well as the median values of World Health Organization Child Growth Standards across all ages. Similar patterns were observed for average height and weight. The nutritional status of North Korean IYC revealed a prevalence of highly underweight (9.3%), stunting (19.1%) and wasting (2.5%) values, and was determined to be significantly lower than values obtained for South Korean IYC (0.8%, 1.8%, and 0.7%, respectively). Conclusion: This study has yielded valid statistics that compare the nutritional status of North and South Korean IYC. Results of this study confirm the prevalence of nutritional status difference between South and North Korea.

Purpose: This study investigates the effect of repeated use of lithium disilicate glass-ceramics on color stability. Methods: In this study, 2 types of lithium disilicate glass-ceramics were used and they were divided into 4 groups after 1st, 2nd, 3rd, and 4th heat pressing. The L^*, a^*, and b^* values of all specimens were measured using the VITA Easyshade Advance 4.0. These values was used to determine the ∆E value and transparency. IBM SPSS Statistics ver. 24.0, a statistical significance level of 0.05 and one-way ANOVA were used for all data. Results: In all groups, the L^* and b^* values were the lowest in the specimens subjected to the 4th heat pressing and the corresponding a^* value was the highest. All specimens showed ∆E values of ≤3.3, indicating color changes that were not visible with the naked eye, and the color difference increased with the number of repeated heat pressing. The transparency of all specimens decreased as the number of repeated uses increased. Conclusion: According to the number of repeated heat pressing, the color difference of Rosetta SP (HASSBIO) was larger than that of IPS e.max Press (Ivoclar Vivadent), but it was clinically acceptable in all groups. Moreover, transparency decreased as the number of heat presses increased in all groups. According to the above findings, the lithium disilicate glass-ceramic has high color stability due to repeated heat pressing, implying that it can be used in clinical settings regularly.

Objective: To evaluate the effectiveness of computed tomography (CT) Hounsfield unit histogram analysis (HUHA) in postoperative pancreatic fistula (PF) prediction. Materials and Methods: Fifty-four patients (33 males and 21 females; mean age, 65.6 years; age range, 37-89 years) who had undergone preoperative CT and pancreaticoduodenectomy were included in this retrospective study. Two radiologists measured mean CT Hounsfield unit (CTHU) values by drawing regions of interest (ROIs) at the level of the pancreaticojejunostomy site on preoperative pre-contrast images. The HUHA values were arbitrarily divided into three categories, comprising HUHA-A ≤ 0 HU, 0 HU < HUHA-B < 30 HU, and HUHA-C ≥ 30 HU. Each HUHA value within the ROI was calculated as a percentage of the entire area using commercial 3-dimensional analysis software. Pancreas texture was evaluated as soft or hard by manual palpation. Results: Fifteen patients (27.8%) had clinically relevant PFs. The PF group had significantly higher HUHA-A (p < 0.01) and significantly lower mean CTHU (p < 0.01) values than those of the non-PF group. The HUHA-A value had a moderately strong correlation with PF occurrence (r = 0.60, p < 0.01), whereas the mean CTHU had a weak negative correlation with PF occurrence (r = -0.27, p < 0.01). The HUHA-A and mean CTHU areas under the curve (AUCs) for predicting PF occurrence were 0.86 and 0.65, respectively, with significant difference (p < 0.01). The HUHA-A and mean CTHU AUCs for predicting pancreatic softness were 0.86 and 0.64, respectively, with significant difference (p < 0.01). Conclusion: The HUHA-A values on preoperative pre-contrast CT images demonstrate a strong correlation with PF occurrence.

This experiment was conducted to determine the effects of inclusion level of soybean oil (SO) and palm oil (PO) on their digestible and metabolism energy (DE and ME) contents when fed to growing pigs by difference and regression method. Sixty-six crossbred growing barrows (Duroc${\times}$Landrace${\times}$Yorkshire and weighing $38.1{\pm}2.4kg$) were randomly allotted to a $2{\times}5$ factorial arrangement involving 2 lipid sources (SO and PO), and 5 levels of lipid (2%, 4%, 6%, 8%, and 10%) as well as a basal diet composed of corn and soybean meal. The barrows were housed in individual metabolism crates to facilitate separate collection of feces and urine, and were fed the assigned test diets at 4% of initial body weight per day. A 5-d total collection of feces and urine followed a 7-d diet adaptation period. The results showed that the DE and ME contents of SO and PO determined by the difference method were not affected by inclusion level. The DE and ME determined by the regression method for SO were greater compared with the corresponding respective values for PO (DE: 37.07, ME: 36.79 MJ/kg for SO; DE: 34.11, ME: 33.84 MJ/kg for PO, respectively). These values were close to the DE and ME values determined by the difference method at the 10% inclusion level (DE: 37.31, ME: 36.83 MJ/kg for SO; DE: 34.62, ME: 33.47 MJ/kg for PO, respectively). A similar response for the apparent total tract digestibility of acid-hydrolyzed ether extract (AEE) in lipids was observed. The true total tract digestibility of AEE in SO was significantly (p<0.05) greater than that for PO (97.5% and 91.1%, respectively). In conclusion, the DE and ME contents of lipid was not affected by its inclusion level. The difference method can substitute the regression method to determine the DE and ME contents in lipids when the inclusion level is 10%.
