  • This study was conducted to isolate strain for the preparation of fermented antler (Cervus cornu parvum) and evaluate its physiological activities. The growth degrees of twenty-one samples from Bacillus sp., Lactobacillius sp. and mushroom strain on antler extract agar were evaluated in this study, and Bacillus subtilis KH-15, SCB-3, Cordyceps militaris, Phellinus linteus, Inonotus obliquus 26136, and Inonotus obliquus 26147 were selected. The fermented antler extract by C. militaris had relatively higher contents of total sugar (1619.3 ${\mu}g$/mL), uronic acid (302.0 ${\mu}g$/mL), sulfated-glycosaminoglycan (S-GAGs) (119.9 ${\mu}g$/mL) and sialic acid (21.6 ${\mu}g$/mL) than any other extracts. The anti-complementary activities of all fermented antler extracts were higher than non-fermented antler extract, and among these samples, fermented antler extract by C. militaris showed the highest anti-complementary activity (inhibition of 50% total complement hemolysis, $ITCH_{50}$; 50.1% at 1,000 ${\mu}g$/mL). The ability of fermented antler extract by B. subtilis KH-15 to scavenge 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical ($IC_{50}$; 4.97 mg/mL) was significantly the highest (p<0.05), whereas the extract from I. obliquus exerted significantly (p<0.05) high 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity ($IC_{50}$; 16.98 mg/mL) among all samples. The results of this study suggest that physiological effects including immuno-modulating and antioxidant activities of the antler may be increased through fermentation process.

  • The purpose of this study was to investigate the factors affecting dentists' attitudes and dental hygienists' services on dental anxiety in adults. The subjects were 300 adults older than 20 years of age living in Seoul, Gyeonggi, Daejeon, and Daegu. Data were collected using structured questionnaires. Among the distributed questionnaires, 225 respondents were selected as subjects, excluding 74 people who did not answer and 1 person who was not faithful. Data were analyzed using statistical software with a t-test, one-way ANOVA, and multiple regression. As a result, the gender was slightly higher in women (54.7%) than in men, and the last dental visit was less than one year in 59.6% of respondents. Most of the respondents' educational level was higher than college level (79.1%), and the monthly income was less than 2 million won in 53.8 of respondents. This study showed that distrust of dentists affected dental anxiety and anxiety stimulation. Higher reliability of the dentist was correlated with less dental anxiety in patients. Dental anxiety showed statistically significant results in dentist subcategories of patient slight and dentists' trust (p<0.01). Additionally, the factors affecting dental anxiety and anxiety stimulus were knowledge of dental hygienist and distrust of dentist (p<0.01). According to this study, dentists' and dental hygienists' trust of dental staff show the importance of oral health professionals' role in reducing dental anxiety in patients. It is also suggested that efforts should be made to improve public awareness of oral health experts. It is believed that dentists, and dental hygienists need to promoted to become professionals. In addition, a variety of programs have been developed to reduce dental anxiety, so patients need to be comfortable to receive dental treatment.

  • Radiation safety managements in medical institutions are needed to protect certain radiation damages as a part of National Coalition. This study investigates the characteristics of self-efficacy that become the major factor on the knowledge, attitude, and behavior on the radiation safety management of radiation workers as an approach of educational aspects and analyzes the relationship between such factors to provide basic materials for improving the activity level of radiation safety managements. In order to implement the goal or this study, a survey was performed for 1,200 workers who were engaged in radiation treatments in medical centers, such as general hospital, university hospital, private hospital, and public health center for 42 days from July 23,2006. Then, the results of the analysis can be summarized as follows: 1. Average scores on knowledge, attitude, and behavior in the radiation safety management were presented as $75.76{\pm}11.20$, $90.55{\pm}8.59$, $80.58{\pm}11.70$, respectively. Also, the average score of self-efficacy was recorded as $73.55{\pm}9.82$. 2. Knowledge levels in the radiation safety management showed significant differences according to the sex, age, marriage, education, and experience. Also, males of married, older, highly educated, and largely experienced represented high knowledge levels. Attitude levels in the radiation safety management showed certain significant differences according to the type of medical centers in which private hospitals showed a relatively low level compared to that of high levels in university hospitals. Behavior levels in the radiation safety management also represented significant differences according to the age, marriage, education, experience, and types of medical centers. Factors in married, general hospital, older, highly educated, and largely experienced showed high behavior levels. In addition, the self-efficacy showed certain differences according to the marriage and types of medical centers. Factors in married and general hospital demonstrated high self-efficacy levels. 3. Relationship between knowledge, attitude, behavior, and self-efficacy on the radiation safety management showed statistical differences according to the relationship between the knowledge and the attitude, the knowledge and the behavior, the attitude and the behavior, the attitude and the self-efficacy, and the behavior and the self-efficacy. The relationship between the behavior and the self-efficacy was represented as r = 0.482, which was the strongest relationship in such factors. Also, the knowledge and self-efficacy didn't show certain relationships.

  • Cardiac angiography(CA) or cardiac intervention(CI) is one of the major examination methods applied to the detection of cardiovascular diseases using X-rays. These CA and CI procedures require radiation exposure to patients and physicians. We evaluated the radiation dose to cardiac operator during the each case of CA and CI procedures. The number of patients is 113 patients in CA and 34 patients in CI. Mean fluoroscopy time, mean cine time, and mean total cumulative dose area product(DAP) in patients during CA and CI was 165.9 sec vs. 1200.0 sec, 30.31 sec vs 107.5 sec, and $37130.3mGy.cm^2$ vs $213312.6mGy.cm^2$, respectively. Mean dose of thyroid, over chest apron and under chest apron in operator during CA and CI was 15.84 uSv vs 89.81 uSv, 20.16 uSv vs 123.20 uSv, and 0.30 uSv vs 2.40 uSv, respectively. Mean effective dose of operator during CI was about 6 times greater than during CA. Also there was significant inter-relationship between fluoroscopy or cine time and effective dose in operator during CA and CI(p=0.001 and p=0.001, respectively).

  • Purpose: Obesity can lead to several chronic diseases. With a continuous increase in the obesity rates, sustainable healthy weight management among growing adolescents has become essential. This study was conducted to examine the relationship between obesity-related factors and creative convergence ability. This could form the basis for convergence education for the sustainable healthy weight management of adolescents. Methods: Data were collected from 430 adolescents in Daegu, Gyeongbuk, and Gyeonggi regions using a self-administered 5-Likert questionnaire from November to December 2020. Results: The average score of the male students was higher than that of the female students in terms of healthy weight management convergence awareness, creativity, convergence thinking ability, self-efficacy, exercise, and dietary diversity. On the other hand, the dietary restraint score and the number of weight loss attempts were higher in the female students. Dietary restraint, disinhibition scores and weight loss attempts were higher in obese adolescents compared to underweight adolescents. It was found that dietary restraint, convergence thinking ability, problem-solving ability, exercise, and dietary diversity factors had a positive effect on healthy weight management convergence awareness. Healthy weight management convergence awareness, exercise, meal amount management, junk food management, weight loss belief, and weight loss trial experience had a positive effect on dietary restraint. Convergence thinking ability, weight loss experience, and obesity factors had a positive effect on dietary disinhibition. Conclusion: The sustainable healthy weight management education of adolescents is based on weight management knowledge and awareness of convergence, and must include gender differences. Thus, the problem-solving ability for healthy weight management can be creatively cultivated to enhance self-efficacy.

  • In this study, the effects of feed containing citrus byproducts on the physicochemical characteristics and palatability of Korean native chickens were investigated. The Korean native chickens used in this study were divided into two groups: T0 (chickens that were not fed citrus byproducts until they were 39 weeks old) and T1 (chickens that were fed citrus byproducts). The feed given to the T1 chickens was the same as that given to the T0 chickens for the first 16 weeks. Between weeks $17{\sim}39$, the feed given to the T1 chickens was prepared by adding 4% of the citrus byproducts to the feed given to the T0 chickens. The chickens used in the experiment were chilled for 2 days after being sacrificed. The feed containing citrus byproducts did not cause any statistically significant differences in the breast and thigh characteristics of lightness ($L^*$ value), redness ($a^*$ value), yellowness ($b^*$ value), water-holding capacity, frozen loss, thawing loss and boiling loss. As for the rheological properties, there was no statistically meaningful difference in the breast/thigh characteristics of springiness, cohesiveness, gumminess, and chewiness between the T0 and T1 chickens. However, hardness and shear force were significantly lower in the T1 chickens than in the T0 chickens (p<0.05). The acid and peroxide values were also lower in the T1 chickens than in the T0 chickens, but the difference was not statistically significant. Antioxidant activity was better in the T1 chickens than in the T0 chickens. Thus, the results of the present study show that consumption of citrus byproducts did not affect the color and smell of raw meat. The palatability of boiled meat was significantly better in the T1 chickens than in the T0 chickens.

  • Purpose: The purpose of this study was to analyze the effects of aromatherapy on stress using meta-analysis. Methods: Meta-analysis was done with 21 published studies, and data were analyzed with the SAS 9.1 program. Results: Fifty eight effect size was estimated with data from 21 published studies. Overall mean effect size (ES), and mean effect size of dependence variables according to the type of intervention and subject and according to the total amount of time spent in aromatherapy were estimated. Overall mean effect size of the effects of aromatherapy was .593, and the subjective stress (.983) was most effective in the physiological faculty, followed by mean effect size of cortisol (.648) and pulse (.40). On the other hand, mean effect size of systolic blood pressure (.490) was moderate, and that of diastolic blood pressure (.401) was not large. Mean effect size of elderly (.706) cancer patients was considerable(.337). There were significant differences depending on the subjects. With regards to the types of aromatherapy, the effect size of aroma massage combined with inhalation therapy was .590, and there were no significant differences between the intervention methods. With regards to the time of intervention, $20{\sim}30$ minutes spent in aromatherapy was .730, and there were no significant differences between the times of intervention. The relationship between the effect size and intervention frequency was r=.349 and showed significant difference. Conclusion: This result suggests that aromatherapy is an effective intervention to reduce stress for subjects. Nursing intervention protocol by using aromatherapy should be developed and applied in clinical and community settings. Further studies on the effects of aromatherapy on stress should be done by using meta-analysis.

  • Globally, 1.3 million people develop colon cancer every year, and 600,000 people die each year it. In Korea, colorectal carcinoma was associated with the highest death rate, accounting for 8,380 people, among solid cancers in 2015. Among the various methods for the diagnosis and study of colorectal carcinoma, the results obtained by cytogenetic and molecular genetic methods were compared. Detection rate was 47% in 18q, 40% in 17p, 27% in 22q, and 17% in 10q via CGH; detection rate was 57% in D18S59, 50% in D18S68, 50% in TP53CA, 47% in D18S6940% in D22S274, 37% in D22S283, 27% in D10S187, and 23% in D10S541 with LOH. Microsatellite marker matching rates were 100% in D22S274, 100% in D22S283, 100% in D10S186, 100% in D10S187, 100% in D10S541, 93% in D18S69, 93% in D18S68, 92% in TP53CA, and 89% in D18S59. The agreement rate between the two methods was 94.4% based on positive results using CGH. Based on the advantages of CGH, which was the ability to obtain information regarding the entire tumor genome at once, this experiment could identify the region with significant deletion using CGH and the more limited region LOH, with a completely different approach. LOH in the recurrent high-risk group, 18q21, was helpful in the selection of treatment modalities and in prognostic estimation as well as making the most appropriate decision for treatment. Therefore, it is suggested that LOH with surgical site tissues could be one of the treatment methods for recurrent high-risk group among patients with colorectal carcinoma.

  • Objective: As per the requirement of Korean Food and Drug Administration, this post-marketing surveillance was conducted in Korea to evaluate the safety and reactogenicity of Poliorix$^{TM}$ following its introduction in 2006. Methods: In this open, multicenter study, the vaccine was administered as per the current practice of Korean doctors and in reference to the guidebook by the Korean Pediatric Society and as indicated in the Korean label which was as follows - for primary vaccination three doses were given to infants at ages 2, 4 and 6 months whereas, for the booster dose a single dose was given to children aged 4-6 years. Safety data during this six year surveillance was collected using diary cards which were distributed to the parents to record adverse events. Results: A total of 639 subjects were enrolled into the study. Of these, 617 subjects and 22 subjects received the vaccine as a primary and booster dose, respectively. At least one unsolicited symptom was reported in 11.4% (73/639) of the subjects during the 7-day follow-up period; upper respiratory tract infection (2.5%;16/639) was the most frequently reported unsolicited symptom. One subject reported at least one unsolicited symptom (gastroenteritis) of grade 3 intensity within the 31-day post-vaccination period. Approximately 1.7% (11/639) of subjects reported 13 serious adverse events (SAEs). All SAEs were resolved by the end of the study. Conclusion: In Korea, primary and booster vaccination with Poliorix$^{TM}$ was well-tolerated in healthy subjects when administered according to the prescribing information as part of routine clinical practice.

  • The common word flavonoids is often used to classify a family of natural compounds, highly abundant in all higher plants, that have received significant therapeutic interest in recent years. Naringin is associated with a reduced risk of heart disease, neurodegenerative disease, cancer and other chronic diseases; however the molecular basis of this effect remains to be elucidated. Thus we attempted to elucidate the anti-allergic effect of Naringin in ovalbumin (OVA)-induced asthma model mice. The OVA-induced mice showed allergic reactions in the airways. These included an increase in the number of eosinophils in bronchoalveolar lavage (BAL) fluid, an increase in inflammatory cell infiltration into the lung around blood vessels and airways, airway luminal narrowing, and the development of airway hyper-responsiveness (AHR). The administration of Naringin before the last airway OVA challenge resulted in a significant inhibition of all asthmatic reactions. Accordingly, this study may provide evidence that Naringin plays a critical role in the amelioration of the pathogenetic process of asthma in mice. These findings provide new insight into the immunopharmacological role of Naringin in terms of its effects on asthma in mice.
