Background: The objective of behavioral guidance is to establish effective communication that aligns with a child's requirements to manage disruptive behavior. This study aimed to evaluate the effectiveness of the Tell-Show-Do and Ask-Tell-Ask techniques in managing dental anxiety in children during their initial appointment. Methods: The study included 50 children (28 boys and 22 girls) without any prior experience between the ages of 7 and 11 at their first dental visit. The children were randomly categorized into two groups: Group 1, Tell Shows Do, and Group 2, Ask-Tell-Ask. Subsequently, all children underwent noninvasive treatment procedures such as restorations, sealants, and oral prophylaxis. Furthermore, behavioral management techniques were employed based on the allocated group. Finally, anxiety levels for all children were assessed using the Raghavendra, Madhuri, and Sujata Pictorial Scale (RMS-PS) and heart rate at three different intervals (before, during, and after). The obtained data were entered into Microsoft Excel, and statistical analysis was performed using SPSS software. A paired t-test and Mann-Whitney U-test were used to compare the mean and median values of the two groups and determine their effectiveness. Results: Children in the TSD group exhibited statistically significant heart rates and RMS-PS scores in intra-group comparisons. However, children in the ask-tell-ask group showed a significant reduction only in the RMS-PS scores (P < 0.001) but not in the measures used to assess heart rate (P < 0.001). Conclusion: Tell-Show-Do was more effective than ask-tell-ask in alleviating dental anxiety in children. The simultaneous application of these two strategies can synergistically alleviate dental anxiety during a child's initial dentist appointment.
Background: Olive flounder, Paralichthys olivaceus, is an economically important aquaculture species in Korea. Olive flounders have been heavily damaged by streptococcal infections every year and are treated with antibiotics. However, antibiotic abuse is causing the emergence of resistant strains, and to overcome this, research has shown that new antibiotics must be applied. Tylosin is a relatively safe antibiotic and has good activity against Gram-positive bacteria and mycoplasma. We studied the therapeutic effects and side effects of tylosin on Streptococcus parauberis-infected olive flounder. Methods: After artificial infection of olive flounder with S. parauberis SPOF18J3, an appropriate dose of tylosin was confirmed by intramuscular injection (I.M.) at 2.5, 5, 10, and 15 mg/kg, and oral administration at 10 and 20 mg/kg. After I.M. and oral administration dosing of tylosin, side effects were confirmed by serological analysis, histopathological analysis, and median lethal dose (LD50) analysis at both an appropriate concentration and a high concentration. Statistical analysis was performed using one-way analysis of variance (ANOVA) and Tukey's test (p < 0.05). Results: The appropriate I.M. and oral administration concentration of tylosin administered to olive flounder infected with S. parauberis SPOF18J3 was found to be 10 mg/kg. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were showed not significantly different between the control group and the experimental groups. The histopathologic results showed mild inflammatory responses in muscle and tubular vacuolization and tubular atrophy appeared, but there were no significant differences between the groups. The LD50 was confirmed to be 461 mg/kg. Conclusion: In this study, an effective treatment method was provided by verifying the treatment effects and side effects of tylosin in olive flounder infected with S. parauberis, which can be applied directly to aquaculture sites. In addition, these results may be used as a reference for evaluation required upon request to obtain approval for tylosin antibiotics as fishery antibiotics in Korea. After approval, it is possible that a fishery disease manager will be able to prescribe and sell the antibiotic tylosin.

The objective of this study was to evaluate the effect of different levels of palm kernel meal (PKM), an alternative to corn, on the quality of pork. A total of 72 crossbred pigs ([Yorkshire ${\times}$ Landrace] ${\times}$ Duroc) were assigned into four dietary treatments (PKM level of 0, 4, 8, or 12%). After 12 wk, one pig of median weight in each pen was selected and slaughtered to analyze meat quality. The color, free radical scavenging activity, lipid oxidation, texture, composition of fatty acids, and sensory qualities of pork loin were evaluated post slaughter. When the levels of PKM in the diet increased, the $L^*$-value of pork loin decreased, whereas $a^*$-value and total saturated fatty acids increased. 2-Thiobarbituric acid reactive substance (TBARS) values of pork loin were lower in groups treated with 8 and 12% PKM than in the control group at day 0; this difference, however, was not observed at day 3 and 7. The results of texture analysis showed that increasing the PKM ratio decreased hardness, chewiness, and springiness at day 7. The sensory test, however, indicated no differences between the control and treated groups. These findings show that finisher pigs could tolerate PKM as a replacement for corn; PKM did not negatively affect the quality of pork, indicating that it can be utilized as feed.

The purpose of this study was to investigate the acute(4 hrs) and repeated-dose(6 hrs a day, 5 days a week, 8 weeks) toxic effects of 1-bromopropane(1-BP) on Sprague-Dawley (SD) rats which were treated by inhalation. The results were as follows ; 1. The median lethal concentration($LC_{50}$) was estimated 14,374 ppm(confidence limit 95% ; 13,624~15,596 ppm) in acute inhalation. Abnormal clinical signs related to the 1-BP were not observed with the acute inhalation dose. Gross findings of necropsy revealed no evidence of specific toxicity related to the 1-BP. 2. By sub-acute inhalation the body weights of male and female were significantly reduced(p<0.001) by the dose of 1,800 ppm compared with control group, while the relative weights of liver were significantly increased(p<0.001) in both sexes. However there were no significant variation in food consumption, urine biochemistry, hematology and blood biochemistry for the exposed rats compared with the control rats. Abnormal clinical signs and gross findings of necropsy related to the 1-BP were not shown. No toxicologic lesions were observed by the histopathological test.

Purpose: We analyzed outcomes of patients with prostate cancer undergoing either radical retropubic prostatectomy (RRP) +/- salvage radiation or definitive radiation therapy (RT) +/- androgen deprivation. Materials and Methods: From 2003-2010 there were 251 patients who underwent RRP and 469 patients who received RT (${\geq}7,560cGy$) for prostate cancer. Kaplan-Meier analysis was performed with the log-rank test to compare biochemical control (bCR), distant metastatic-free survival (DMPFS), and prostate cancer-specific survival (PCSS) between the two groups. Results: The median follow-up was 70 months and 61.3% of the men were African American. For low risk disease the 6-year bCR were 90.3% for RT and 85.6% for RRP (p = 0.23) and the 6-year post-salvage bCR were 90.3% vs. 90.9%, respectively (p = 0.84). For intermediate risk disease the 6-year bCR were 82.6% for RT and 59.7% for RRP (p < 0.001) and 82.6% vs. 74.0%, respectively, after including those salvaged with RT (p = 0.06). For high risk disease, the 6-year bCR were 67.4% for RT and 41.3% for RRP (p < 0.001) and after including those salvaged with RT was 67.4% vs. 43.1%, respectively (p < 0.001). However, there were no significant differences between the two groups in regards to DMPFS or PCSS. Conclusion: Treatment approaches utilizing RRP +/- salvage radiation or RT +/- androgen deprivation yielded equivalent DMPFS and PCSS outcomes. Biochemical control rates, using their respective definitions, appeared equivalent or better in those who received treatment with RT.
From of old, labor has been accompanied by pain and much effort has been mode to eliminate or diminish the amounts of pain during labor. Little concern has yet been given to the subjective meaning of pain in labor. Recently, rates of cesarean section in Korea and in some other nations have increased rapidly and some investigators are reporting negative reactions such as anger, disappointment and feeling of loss due to lack of control over labor and its pain. These findings are thought to suggest that control of labor and its pain gives some meaning to the laboring woman. Thus the investigators sought to discover the meaning of pain during labor for Korean women. Specific objectives of this study were to explore the meaning of pain in labor to the mothers, their reactions to the experience of labor add their preference for delivery method. The subjects of this study were 95 mothers who delivered their babies in hospital from September 989 to May 1990 : 45 gave birth by vaginal delivery, and 50 by cesarean section. Data were gathered through direct interviews by the investigators, and questions were focused on five areas i.e. mothers' feelings about delivery and their babies, their feelings about of having more children, the most difficult aspect about this labor and delivery, and what they thought the differences were between vaginal delivery and cesarean section. After interview, mothers' answers were summarized, and classified according to the degree of positive or negative attitude. To ascertain the difference in meaning of labor pains and reaction to delivery experience between mothers delivered vaginally and by cesarean section a Median test was done using an SAS. Results were as follows. 1. More mothers who had delivered vaginally realized that they “have became a mother” than those who had a cesarean section(X$^2$=8.409, df=3, p=0.038). 2. Immediate reaction to their delivery experience was more positive for mothers who had a cesarean section. 3. These Korean mothers expressed preference for vaginal delivery. Suggestions for further research on the meaning for mothers of their experience of labor, and on the meaning of pain for mothers who have a cesarean section were made.
The purpose of this study was to investigate the current status of postpartum depression intervention program performed in Korea and to evaluate its effectiveness. Of the Korean academic journals reported until November 2018, 13 experimental studies were selected and used for final analysis. The average age of the subjects was 26.9 to 34.4 years, and subjects were puerperal women or couples. The sample size was 6~39 (mean: 20.4) in the experimental group, 5~40 in the control group (mean: 20.0), and the intervention program consisted of 0.5~12 weeks/2~14 sessions/10~120 minutes per session. The design of all the studies was a non-equivalent control group pre-post test design. The main dependent variables, postpartum depression, fatigue, and maternal role self-confidence, were all found to have a statistically significant median level of effect size in the meta-analysis. This study confirms the composition and effects of various experimental studies used to mediate postpartum depression in Korea. This could be used as specific evidence-based data to form an optimal postpartum intervention program.
Purpose: Necrotizing enterocolitis (NEC) is one of the most serious complications of prematurity. Many risk factors can contribute to the development of NEC. The epidermal growth factor (EGF) plays a major role in intestinal barrier function, increases intestinal enzyme activity, and improves nutrient transport. The aim of this study was to assess the role of epidermal growth factor in the development of NEC in preterm neonates. Methods: In this study, 130 preterm neonates were included and divided into 3 groups, as follows: group 1, 40 preterm neonates with NEC; group 2, 50 preterm neonates with sepsis; and group 3, 40 healthy preterm neonates as controls. The NEC group was then subdivided into medical and surgical NEC subgroups. The serum EGF level was measured using enzyme-linked immunosorbent assay. Results: Serum EGF levels (pg/dL) were significantly lower in the NEC group (median [interquartile range, IQR], 9.6 [2-14]) than in the sepsis (10.1 [8-14]) and control groups (11.2 [8-14], P<0.001), with no significant difference between the sepsis and control groups, and were positively correlated with gestational age (r=0.7, P<0.001). A binary logistic regression test revealed that low EGF levels and gestational ages could significantly predict the development of NEC. The receiver-operating characteristic curve for EGF showed an optimal cutoff value of 8 pg/mL, with 73.3% sensitivity, 98% specificity, and an area under the curve of 0.92. Conclusion: The patients with NEC in this study had significantly lower serum EGF levels (P<0.001), which indicated that EGF could be a reliable marker of NEC in preterm neonates.
Background: Intraoral local anesthesia is essential for delivering dental care; however, injection of this local anesthetic is perceived as the most painful and distressing agent for children, parents, and healthcare providers. Reducing pain as much as possible is essential to ensure smooth subsequent treatment procedures, especially in pediatric dentistry. In clinical practice, oral sucrose administration has been reported to decrease the pain during heel lance and cold pressor tests in neonates and children. This study aimed to determine whether the prior administration of a 30% sucrose solution reduced the pain related to inferior alveolar nerve block in children. Methods: A total of 42 healthy children aged 7-10 years requiring dental treatment of mandibular molars involving inferior alveolar nerve block were recruited. The participants' demographic details were recorded, height and weight were measured, and the anesthetic injection was delivered after receiving the respective intraoral sucrose solution and distilled water by the intervention (group 1) and control (group 2) group participants for 2 min. The subjective pain perceived during injection was measured using an animated emoji scale. The pain scores between the groups were compared using the Mann-Whitney U test. Results: The median pain score and range for the intervention and control groups were 4 (2 - 6) and 6 (4 - 8), respectively, and statistically significant differences (P < 0.001) were observed in the intervention group. Age, sex, height, and weight did not influence the analgesic effect of the sucrose solution. Conclusion: Oral administration of sucrose may relieve pain associated with inferior alveolar nerve block in children.

Objectives: We aimed to describe the reporting patterns of 6 notifiable surveillance diseases in the Republic of Korea, including water- and foodborne infections, from 2012 to 2021. Methods: For the 12,296 cases that met the reporting criteria, we calculated the number of reported cases, including the number of cases confirmed by lab tests or suspected by a physician, the number of cases with delayed reporting and their average days of delay, and the median days required to report the confirmatory test results. Results: The overall number of reported cases consistently increased over the ten years, with a significant rise in the reported cases of typhoid fever, paratyphoid fever, and EHEC. Ninety-five percent of all reported cases were timely reported within one day of diagnosis. Vibrio vulnificus had the highest rate of delayed reporting (6.8% delayed over 1 day, 3.0% delayed over 3 days), while cholera had the lowest rate (1.9% delayed over 1 day, 0.1% delayed over 3 days). The average days of delayed reporting was 6.1 days: the highest for paratyphoid fever (10.8 days) and the lowest for cholera (2.7 days). For typhoid fever and paratyphoid fever, there has been an increase in the proportion of cases with negative test results. For vibrio vulnificus, there has been an increase in the proportion of cases with confirmed positive test results. As for EHEC, there has been a recent increase in cases with no confirmatory tests. Conclusions: Reported cases of water- and foodborne infectious diseases increased, indicating improved surveillance system completeness. However, for paratyphoid fever, improvements are needed in terms of timely notification by healthcare facilities and timely reporting of confirmatory test results.
