This study investigates the characteristics of cookies added with yacon. The addition of yacon powder did not affect the density of the cookies and decreased pH level. The moisture content was the highest in the cookies with 12% of yacon. Spread ratio was the highest in the cookies containing yacon powder. The loss rate and leavening rate of the cookies decreased with increasing amounts of yacon powder. Lightness and yellowness decreased significantly while redness increased significantly with a high content of yacon powder in the formulation. The hardness of the control group was higher than that of the cookies prepared with different levels of yacon powder. The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenolic acid content in yacon powder and cookies. The consumer acceptability score for the 6% yacon cookie group ranked significantly higher than the other groups in overall preference, appearance, flavor, taste and color. Through this experiment, this study exhibited both the functional and health based benefits of yacon when it is added to cookies and confirmed the development feasibility of yacon cookies considering consumer satisfaction.

This research aims to figure the different perceptions on the organization-public relationship between military officials and the locals, and the perception on the support military family welfare. In order to analyse their subject point of view, 217 career soldiers and the 191 local residents surveyed during 3 weeks from 10th February to 28th February, 2014. The results getting from this research were as to follows; First of all, the perception on the military organization-public relationship towards local community is more positive in the military officials(M=5.39) than the locals(M=4.99), but different from the two groups(t=6.93, p<.001). Moreover, there exists statistically significant different in every sub-factors and it means the mutual perception consistency is low. Second, the perception on the support from the locals towards military family welfare of military(M=5.38) is higher(t=6.93, p<.001) than the perception of the locals (M=4.76) and it is statistically significant. Third, the a regression coefficient which indicates the impact on the perception on support military family welfare through the change of organization-public relationship shows statistically significant (${\beta}=.82$(p<.001)). As a result, the perception on the military organization-public relationship of the locals has significant prediction power to the perception on the support military family welfare. And when the perception on the military organization-public relationship of the localsis higher, the perception on the support military family welfare has been changed positively.

Purpose : Forward pulmonary blood flow may be absent in some neonates with Ebstein's anomaly by anatomical or functional pulmonary atresia in association with the elevated pulmonary vascular resistance, patent ductus arteriosus and tricuspid regurgitation. We reviewed the presentation and outcomes of symptomatic neonates with Ebstein's anomaly focusing on the pulmonary atresia. Methods : Clinical presentation and outcome of 15 symptomatic neonates with Ebstein's anomaly seen at Asan medical center from 1998 to 2004 were reviewed. Results : Ten(67%) of 15 patients showed no forward pulmonary blood flow and 6 of them had functional pulmonary atresia. $O_2$ saturation and pH were lower and cardiothoracic(CT) ratio in chest radiography was more increased in the patients with pulmonary atresia than in the patients without pulmonary atresia(P<0.05). pH and CT ratio were not different between the anatomical and functional pulmonary atresia group, but $O_2$ saturation was lower in functional atresia group(P<0.05). 13 patients(87%) were managed with $PGE_1$. 4 of 6 patients with functional pulmonary atresia were treated with inhaled nitric oxide. Surgery was performed in 1 of 5 patients without pulmonary atresia and in 8 of 10 patients with pulmonary atresia during follow-up period(mean 37 months). 3 patients(20%) died and none of patients without pulmonary atresia died. Conclusion : We found that most symptomatic neonates with Ebstein's anomaly had functional or anatomical pulmonary atresia. The neonates with Ebstein's anomaly who had no forward pulmonary blood flow were more symptomatic and needed surgery earlier. Further studies will be needed to distinguish effectively functional and anatomical pulmonary atresia and to manage appropriately neonates with functional atresia.

Purpose: This study aimed to investigate the clinical characteristics of human parechovirus (HPeV) infection in sepsis-like syndrome in infants aged under 3 months. Methods: Medical records of infants aged under 3 months with sepsis-like symptoms who were admitted between July 1, 2018 and August 31, 2018 were reviewed. A multiplex reverse transcription-polymerase chain reaction panel test was performed on the cerebrospinal fluid (CSF). Thirty-nine enrolled infants were categorized into three groups: 11 in group 1 (HPeV detected in the CSF), 13 in group 2 (enterovirus detected in the CSF), and 15 in group 3 (no virus detected in the CSF). Results: Compared with groups 2 and 3, a higher proportion of group 1 had tachycardia, tachypnea, apnea, and hypotension (P<0.05). A significantly lower white blood cell (WBC) count was noted in group 1 than in groups 2 and 3 (5,622±2,355/μL, 9,397±2,282/μL, and 12,312±7,452/μL, respectively; P=0.005). The CSF WBC count was lower in group 1 than in groups 2 and 3 (0.9±1.7/μL, 85.1±163.6/μL, and 3.7±6.9/μL, respectively; P=0.068). The proportion of patients requiring inotrope support (36.6% vs. 0% and 6.6%), mechanical ventilation (18.1% vs. 0% and 0%), and high flow nasal cannula (45.4% vs. 15.3% and 6.6%) was higher in group 1 than in groups 2 and 3. All patients recovered completely without complications. Conclusions: HPeV infection shows a severe clinical course and can cause a severe sepsis-like syndrome in infants aged under 3 months. Early diagnosis and proper treatment of HPeV infection are required.

Background: Chronic paranasal sinusitis is one of the most common disease in the otorhinolaryngologic field. Endoscopic sinus surgery is treatment of choice in chronic paranasal sinusitis. The aim of this study was to evaluate objective and subjective treatment outcomes of endoscopic sinus surgery in adult chronic paranasal sinusitis with or without polyp. Materials and Methods: We reviewed 84 adult patients underwent endoscopic sinus surgery by one surgeon from June 1999 to June 2000, prospectively. We analyzed preoperative and postoperative subjective symptom scores and acoustic rhinometric results. Results: Fifty cases were male and thirty four cases female. The average age was of 33 year-old (range: 17 to 66 years). There was significantly improvement of symptom scores in postoperative 3 months and 6 months compared with preoperative symptom scores. There was significantly increased postoperative total volume of nasal cavity. When we compared high score group with low score group, there was statistically significant improvement of symptom scores between preoperative stage and postoperative 3 months in radiologic grading group. Conclusions: Endoscopic sinus surgery is considered to be effective for the treatment of chronic paranasal sinusitis. It seems to be helpful to employ subjective symptom score system and objective total volume change of nasal cavity through acoustic rhinometric test to analyze effectiveness of endoscopic sinus surgery. In this study, the most important preoperative factor of sinus surgery outcomes is radiologic grading system.

We explored the quality characteristics of Sulgidduk prepared using different amounts of cheese powder (0%, 6%, 12%, 18%, 24%; all w/w); physico-chemical properties were determined. Proximate composition analysis showed that the moisture content of Sulgidduk decreased with a rise in the level of added cheese powder. Lightness and yellowness values were lowest in control Sulgidduk and highest in Sulgidduk with 24% added cheese powder. Texture profile analysis showed that all of hardness, cohesiveness, springiness, and brittleness increased with a rise in cheese powder level. Scanning election microscopy indicated that the number of air cells fell as the ratio of cheese powder to rice powder increased. Sensory evaluation tests indicated that color, cheese smell, and greasiness rose as the cheese powder level increased, whereas softness and moistness fell. Consumer acceptance testing showed no significant difference in overall acceptability scores among samples. In conclusion, we suggest that cheese powder may be incorporated into Sulgidduk without affecting sensory qualities.

Quality evaluation of fish muscle was conducted in olive flounder, Paralichthys olivaceus fed with control or experimental diet containing 0.3% of Obosan (Sungam Co., Korea). Sensory panel members preferred the experimental fish were more preferable than those of control (P<0.01 or 0.05). The difference test was shown that the experimental fish muscle is more firm elastic and palatable than the control ones (P<0.01 or 0.05). The physical properties of meats from fish fed a diet containing Obosan improved qualities with compared to those of control meats. The total amount of free amino acids in muscles from control fish (31.7 mg/100mg), especially with the significant increase of glutamic acid, proline, glycine, alanine and methionine. In all nucleotides and their related compounds, ATP was the most abundant in muscles from fish fed a diet containing Obosan (about 1.9 fold compared to mean of control), however, IMP was more abundant in control muscles.

The purpose of this study was to examine the quality of muffins with 0, 3, 6, 9, and 12% kale powder. The specific gravity of muffins prepared by adding kale powder was higher than the control group. The height of the muffins was not significantly different among all sample groups. The weight of muffins with 9% kale powder was higher than other samples. The volume and specific loaf volume of muffins decreased with the addition of kale powder. The baking loss rate of muffins decreased with the addition of kale powder. The moisture content of the samples with kale powder was higher than the control group, whereas pH was lower than the control group. DPPH radical scavenging activity of the control group was 25.70%, but the samples with kale powder ranged from 34.80 to 53.70%. In color, the L value decreased, but the b value increased significantly with the addition of kale powder. The hardness, springiness, cohesiveness, chewiness, and brittleness of the textural properties of the muffins significantly decrease by addiction of kale powder. Sensory evaluation scores in terms of after swallowing, appearance, flavor, taste, texture, and overall preference of groups with 3% and 6% kale powder did not show any significant differences, and the scores were higher than the control group. Based on these results, thus, using less than 6% kale powder would be proper to make muffins.
