  • Objective: The purpose of this study was to assess the changes in height and inclination of the articular eminence during the growth period. Methods: One hundred and sixty subjects (71 males and 89 females) with a normal skeletal pattern and TMJ function, ranging in age from 5.9 to 19.7 years were divided according to their chronological age into six groups. Lateral individualized corrected TMJ tomograms were taken of all subjects, and the height and inclination of the articular eminence were measured. UNIANOVA was used to compare the differences between the age groups. Mann-Whitney test was used to compare the differences between male and female subjects. Results: The height and the inclination of the articular eminence were increased and became steeper with age, and the height and the inclination were larger in male than in female subjects. Conclusions: Dynamic changes in the height and the inclination of the articular eminence were observed during the growth period, therefore a full understanding of the growth of the articular eminence is important for orthodontic and orthopedic treatment in this period.

  • Double-stranded RNA (dsRNA) has been applied to control insect pests by its suppressive activity against specific target genes. Integrin is a heterodimer (${\alpha}$ and ${\beta}$) transmembrane protein and plays a critical role in cell-to-cell or cell-to-extracellular matrix interactions in eukaryotes. Suppression of ${\beta}$ subunit integrin gene expression by its specific dsRNA (= dsINT) induces significant mortality against target insects. Furthermore, a recombinant bacterium expressing dsINT is potent to kill target insects. However, it is necessary to develop a formulation technique of the dsRNA-expressing bacteria to apply the bacterial insecticide against field populations. This study formulated the recombinant bacteria by freeze-drying and tested its control efficacy against target insects. The formulation maintained significant insecticidal activity against last instar larvae of Spodoptera exigua. While a commercial Bacillus thuringiensis (Bt) insecticide exhibited only about 60% insecticidal activity against S. exigua last instar, an addition of the dsINT-expressing bacterial formulation significantly enhanced the Bt insecticidal activity. The dsINT-expressing bacterial formulation exhibited relative selectivity to target insects depending on sequence similarity. These results indicate that a freeze-dried form of dsRNA-expressing bacteria keeps its insecticidal activity.

  • Class III malocclusion patients can be approached with many different types of treatment methods, and thus, each patient's problems must be accurately evaluated to allow selection of the best possible treatment method. Cephalometric analysis is an essential part of diagnosis and treatment planning of orthodontic patients, and it would certainly be helpful if reliable cephalometric guidelines could be set. The author divided 482 Class III malocclusion patients(253 males and 229 females) into fourgroups according to different types of treatment methods they have received to correct imbalance between upper and lower jaws: 1) orthopedic appliance (face mask & RPE), 2) camouflage treatment with fixed appliance, 3) surgical-orthodontic treatment, 4) cross-bite correction with removable plates/ functional appliance. Cephalometric values at the time of first clinical examination were compare among the four groups. Cephalometric analysis indicates the following results: 1)the amounts of antero-posterior and vertical skeletal discrepancies and dental compensation were greatest in surgery group 2) SNB, Wits, distance from Nasion Perpendicular Plane to point a facial angle, facial convexity, and APDI were greater in orthopedic appliance group than fixed appliance(camouflage) group, but there was no statistical difference 3) removable plates/ functional appliance group showed least amounts of skeletal discrepancies and dental compensation with statistical significance.

  • In order to analyze factors that support effective health care delivery system, this study aimed to research general public's perception on the functions of medical institutions(based on the levels of treatment: primary care, secondary care, and tertiary care), choices of medical institution when contracted with an unfamiliar disease, and recognition of diseases based on their severities. We collected data using self-administered survey from 400 general public living in Seoul, S. Korea from April 25 to May 18, 2011. The analysis was conducted using frequency analysis, chi-square test, and t-test; we analyzed the data to see if there are differences based on gender, age, and level of education. The result of both recognition of functional differences of medical institutions and selection of medical institutions when contracted with unfamiliar diseases showed that there were no significant differences based on the gender; however there were significant differences when considering the age and education. Looking at the result of the knowledge of the disease classification based on its severity, there were significant differences in age, gender, and education. In order to provide sustainable and effective health care delivery system, utilization of primary care as well as education and promotion regarding the functional differences of medical institutions and classification of disease based on its severity need to be encouraged.

  • Objective : The purpose is to analyze the effects of parent training interventions in reducing the symptoms of Attention Deficit Hyperactivity Disorder (ADHD) and to provide a basis for the effects. Methods : We collected literature published in international academic journals from 2009 to 2019 through ProQuest and Scopus databases. The search key terms were (ADHD OR Attention Deficit Hyperactivity Disorder) AND (Parent OR Mother OR Father) AND (Training OR Program OR Therapy OR Intervention) AND (Randomized OR Randomised OR Randomly). The PEDro scale was used to evaluate the quality of the studies, and a meta-analysis was conducted through Comprehensive Meta-Analysis 3.0. Results : Of 628 studies that we reviewed, 20 were eligible for inclusion. of parental training interventions for children with ADHD appeared close to a medium effect size while parent-child interventions (0.639) appeared to have a medium to large effect size. Oppositional defiant behavior and conduct disorder (0.737) in children and children's emotions (0.679) appeared close to a large effect size. ADHD symptoms hyperactivity and impulsivity (0.590) and child behavior (0.521) appeared to be over a medium effect size. We chose a random-effects model since heterogeneity tests showed significant results. Conclusion : We were able to confirm the effects of parent training interventions on the symptoms of children with ADHD. This will be used as evidence to provide a clinical basis for occupational therapists. More research related to parental training interventions should be carried out to ensure better reporting in the future.

  • The roots of Achyranthes japonica Nakai were extracted with 100% aqueous and concentrated subfraction was separated with ultra-performance liquid chromatography-based activity profiling. Three compounds were isolated from the subfraction 5 through the repeated prep- high performance liquid chromatography column chromatography. According to the results of physico-chemical and spectroscopic data including NMR and MS, the chemical structures of the compounds were determined as ecdysterone (1), 25S-inokosterone (2), and 25R-inokosterone (3). Three phytoecdysones were showed weak inhibitory activity for thymus and activation-regulated chemokine expression levels in tumor necrosis factor (TNF)-${\alpha}$ plus IFN-${\gamma}$ induced HaCaT cells, respectively. However, those compounds 1-3 were exhibited the most potent inhibition (80-95% at $200{\mu}g/mL$) against TNF-${\alpha}$ expression levels in A23187 plus phorbol-myrisrate acetate-induced RBL-2H3 cells. As result, 100% aqueous extract of A. japonica has an excellent anti-atopy activity. It could be used to a large range of functional anti-atopy cosmetics.

  • We investigated ${\alpha}$-amylase, ${\alpha}$-glucosidase and lipase inhibitory activity of extracts collected from wild plants in Gangwon-do. 90 wild plants were collected and their water and ethanol extracts were obtained. Results of measuring ${\alpha}$-amylase inhibitory activity indicated more than 80% of activity inhibition in 10 mg/mL concentration for ethanol extracts of three plants and water extracts of two plants. For ${\alpha}$-glucosidase inhibitory activity, ethanol extracts of thirteen plants and water extracts of three plants showed more than 80% of activity inhibition in 10 mg/mL concentration. In the experiment of inhibiting lipase activity, ethanol extracts of seven plants and water extracts of one plants showed above 80% of activity inhibition in 10 mg/mL concentration. These results suggest that the selected extracts could be potentially used as a resource of bioactive materials for health functional foods.

  • This study was perform to examine the feasibility of cooking processing using the rice added the 70% ethanol extract of pigmented rice bran layer. Four rice samples, including normal rice, glutinous rice, pigmented-normal rice, and pigmented-glutinous rice were compared the properties of physico-chemical, texture, and sensory evaluation. Pigmented rice varieties had a higher amylose content, but shorter length in glucose chains than non-pigmented rice varieties. The enthalpy for gelatinization was found to increase in pigmented rice, which need more energy for gelatinization of starch in cooking. The hydrolysis rate by glucoamylase in rice added pigmented bran extract was higher than pigmented rice. Rice with pigmented bran extract had higher glutamine content, but lower asparagine content and no difference in fatty acid composition, which affect palatability. Cooked rice added pigmented bran extract was less retrograded than pigmented rice during the storage period. Moreover, cooked rice added pigmented bran extract was more acceptable in sensory evaluation. Based on the results, the use of rice added pigmented bran extract instead of pigmented rice in grain processed food have advantageous effects in palatability of polished rice and phytochemicals of pigmented non-polished rice. This study will help develop new health-promoting rice products.

  • Objectives: The aim of this study was to develop a Phlegm Pattern Questionnaire for Functional Dyspepsia (PPQ-FD) by modifying a previously developed Phlegm Pattern Questionnaire (PPQ) and to verify its reliability and validity. Further objectives were to obtain the optimal cut-off value for the PPQ-FD for standardization and for clinical use. Methods: The PPQ-FD was developed by extracting the major symptoms of the phlegm pattern in functional dyspepsia and by using the Delphi method to administer a requested importance survey to experts. The reliability, validity, and optimal cut-off value of the PPQ-FD were analyzed by enrolling a total of 60 subjects in this study. Thirty patients were diagnosed with both functional dyspepsia and phlegm pattern and thirty patients were diagnosed with only functional dyspepsia. All participants were requested to fill out the PPQ-FD. Results: No statistically significant differences were detected in the two groups for sex distribution, age, or body mass index. Five of the survey questions negatively affected its reliability; therefore, we decided to exclude those five questions on further inspection. The Cronbach's α coefficient of the revised PPQ-FD was 0.853, and clinical validity was verified. Construct validity was analyzed by factor analysis and identified four factors. Statistically significant positive correlations were found between the revised PPQ-FD and other dyspepsia scales, such as the SQDQ, SSQD, VAS, NDI-K, and FD-QoL scales. The VAS had particularly strong positive correlations with the PPQ-FD. Conclusions: The PPQ-FD developed in this study has fundamental reliability and validity for use as a pattern-diagnosis questionnaire. The PPQ-FD can help to diagnose the phlegm pattern in patients with functional dyspepsia.
