Purpose : This study aimed to critically analyze published research papers in Journal of Korean Academy of Sensory Integration and to investigate the research field and trends. Methods : Types of studies, research trends, levels of evidence, participants, funding sources and research areas were analyzed and described by using 97 selected studies published between 2003 and 2014. Results : Every 5 years, the most frequent type of study was experimental research. The numbers of experimental studies and review studies have been increasing. The most frequent level of evidence was one group non-randomized study, followed by case reports. The highest percentage of participants were children with disability and the most common diagnoses were pervasive developmental disorder, developmental delay and intellectual disabilities. Most of the participants was elementary school students and the most frequent sample size was below 10. The percentage of research grant from Korean Academy of Sensory Integration has been over 50% since 2008. The research areas focusing on the standardized assessments were mostly sensory modulation, interaction and development and the non-standardized assessments were behavior observation and clinical observation. Conclusion : Higher level of studies and comprehensive research methods will be needed. The standardized assessment tools with the high sensibility on sensory integration which developed in the domestic need to be developed. Thus, it will be able to contribute to the evidence based practice in occupational therapy.

The purpose of this study is to explore the relative influences of juvenile delinquency using variables from Hirschi's social bonding theory, Agnew's general strain theory, Gottfredson and Hirschi's self-control theory, and Akers' social learning theory. The data derived from a sample of 2,018 high school students taken from National Youth Policy Institute in 2013. Multiple OLS regression analysis indicated that social learning theory has the greatest impact on dependent variables than other theories. The results of regression analyses also explore the notion that without the social bond, general strain, and self-control variables, there is very little loss of explained variance when these variables are removed from the full equation. However, when the social learning factors are eliminated from the full equation, the change in $R^2$ is dramatic. This result supported the idea that social learning variables had the strongest effect on the juvenile delinquency of Korean adolescents. The most important implication of this study is that it is the first study to test four major theoretical models for juvenile delinquency in Korea. It also makes a number of important contributions toward the further utilization of social learning in investigating juvenile delinquency for Korean high school students.

Purpose: The purpose of the study was to find the strategies of mental health screening in school. Based on the literature review, we discuss the importance of screening students in schools for mental health problems. Methods: Data from the 2008 Korean Mental Health Screening in Schools(2008-KMHSS) are used to estimate the outline of this screening. We administered the questionnaire for satisfaction of 2008-KMHSS for students(N=1,280), parents(N=2,672), school nurses(N=75), teachers(N=685), district personnels(N=6), and mental health center staffs(N=37). Also we interviewed a part of them by telephone and e-mail. And we reviewed the tools and methods for screening students for emotional/behavioral problems. Results: Mental health screening in schools is a very important, yet worrisome, agenda that is in its very early stages. From the 2008 Korean Mental Health Screening in Schools, 9,588 students(12.9%) needed more evaluation in the first stage. Of these, 6,910(72.1%) completed the second stage screening. In this sample, 1,975(28.6%) utilized the mental health services in school or community. 38.3% of students and 43.7% of their parents notified the 2008-KMHSS. But only 12.1% of students and 10.9% of their parents dissatisfied with the screening. 9.9% of teachers and 22.7% of school nurses dissatisfied with the screening. Among them the school nurses were mostly dissatisfied, and they complained work burden from KMHSS. Mental health center staffs complained similar issues. The Children's Problem-behavior Screening Questionnaire(CPSQ) and Adolescents' Mental-health & Problem-behavior Screening Questionnaire(AMPQ) were compatible to screen students in schools for mental health problems in first stage. Conclusion: Mental health screening in schools needs careful planning and implementation. For successful mental health screening in schools, several elements need to be considered: careful planning, collaboration, staff training, and integrative mental health programs and services in community or schools.

The main purposes of this study were to analyze the moderating effect of parenting knowledge in the relationship between socio-demographic factors and parenting style. This study was conducted with the data from 'Panel Study Korean Children(2009).' Among the original data, a sample of 1,637 mothers with infants ranged from 13 to 18 months old was selected. The results of this study were as follows. First, there were significant differences in child's birth-order, mother's education level, and monthly family income. Second, there was a statistically significant difference in the parenting style of mothers in their parenting knowledge. That is, the mother with a high score in parenting knowledge reported more positive parenting style. Lastly, the interaction effects between socio-demographic variables and parenting knowledge on parenting style were statistically significant only with the variables such as child's birth-order and mother's education level. The mothers who cared for their first child and got a high score in parenting knowledge showed the most desirable parenting style, and the mothers whose educational level was under high school graduation and parenting knowledge score was low reported the lowest score in parenting style. These results suggest parenting knowledge should be subject-specifically provided as the differences in socio-demographic variables.

Prevotella intermedia has been implicated as a potent pathogen in many kinds of periodontal, pulpal and periapical diseases. However, it has been isolated from periodontally healthy adults and from edentulous children as well. The intraspecies heterogeneity of Prevotella intermedia has been demonstrated in early studies and finally Shah & Gharbia confirmed the existence of 2 DNA homology groups and proposed dividing Prevotella intermedia into 2 species, Prevotella intermedia and Prevotella nigrescens. This study was designed to examine the frequency of Prevotella intermedia and Prevotella nigrescens in diseased periodontal pockets and healthy gingival sulcus of Korean people by PCR based on 16s ribosomal DNA sequence. One hundred adults who had adult periodontitis but not taken any periodontal treatment or antibiotics during previous 6 months and 50 adults who had healthy periodontal tissue were selected for this study. The sulcular fluid was collected into VMGA by sterilized paper point and diluted to 1,000 times in anaerobic chamber. $100{\mu}{\ell}$ of sample was cultured in $37^{\circ}C$ for 10 days. Among the bacterial colonies, BPB were selected and cultured in BHI broth and then Prevotella intermedia was identified through Gram staining and biochemical test. Identified Prevotella intermedia was cultured again and centrifuged. DNA was extracted from the pellet using several reagents. PCR was performed by previously designed primer. The results were followed. 1. BPB were isolated from 39 of 100 samples of diseased periodontal pockets(39%). 2. Prevotella intermedia was identified from 24 of 39 BPB samples. 3. Among 24 Prevotella intermedia, 21 were confirmed as Prevotella inter - media(87.5) and 2 were confirmed as Prevotella nigrescens(8.33%). 4. BPB were isolated from 9 of 50 samples of periodontally healthy patients. Among them only two were identified as Prevotella intermedia, that is, one was confirmed as Prevotella intermedia and the other was Prevotella nigrescens.

The purpose of this study is to explore further understanding of variables, besides father's alcoholism, which relates to psychosocial adjustment among ADAF(adult daughters of alcoholic fathers). This study examines the relationship between father's alcoholism, family functioning, parental attachment and the psychosocial adjustment among the ADAF. From a larger sample of 463 female college students, 160 ADAF and a matched group of non-ADAF were identified to participate in the study. This survey was conducted in Seoul and Gyungi-do area. Participants completed self-report questionnaires, "The Korean Version of Children of Alcoholics Screening Test", "Inventory of Parent and Peer Attachment", "Satisfaction With Life Scale", "Self-esteem", "Beck Depression Inventory" and "Family Environment Scale". Path analyses was used to test the research question. Findings indicated that father's alcoholism had no direct effect on both the psychosocial adjustment of the ADAF and the family functioning. But father's alcoholism was significantly related to parental attachment. Family functioning was significant predictor of attachment to parents as well as psychosocial adjustment. Finally family functioning is important cause for parental attachment and psychosocial adjustment, specifically self-esteem and life satisfaction outcomes only. Therefore parental attachment was function as a mediator in the relationship between family functioning and psychosocial adjustment. In conclusion, this study showed that father's alcoholism did not predict outcome. We need to reconsider the assumption that direct link exists between adult adjustment difficulties and the presence of father's alcoholism. Implications for clinical and theoretical work with ADAF are discussed.

Parabens were commonly used for preventing the growth of microorganisms as preservatives in the pharmaceutical, cosmetic and food industry. Also, parabens are known endocrine disruptors because of their estrogenic effects on human. Parabens affect the endocrine system and show adverse effect such as, genital malformations, precocious puberty and testicular cancer in young children, infants and fetuses. In this study, we developed analytical method for four parabens (methyl paraben, ethyl paraben, propyl paraben, butyl paraben) in human breast milk which frequently consumed by newborn baby. The analytes were extracted using liquid-liquid extraction (LLE) after enzyme hydrolysis with protease and lipase, then quantitative analysis was performed by liquid chromatography tandem mass spectrometry (LC-MS/MS). The method validation results were as follows; the linearity of calibration curves were excellent with coefficient of determinations (r²) higher than 0.999, the limit of detections (LODs) were 0.019~0.044 ng/mL, the accuracies were 85.3~105.9% and the precisions were lower than 10%. The average concentration ± standard deviation of parabens in ten human breast milk sample were MP 0.660 ± 0.519 ng/mL, EP 1.631 ± 2.081 ng/mL and PP 0.326 ± 0.320 ng/mL, and BP was not detected.

The aim of this study was to determine the efficacy of a 3 tone plaque disclosing gel in assessing the risk of caries related to the population of Streptococcus mutans, Streptococcus sobrinus, and Lactobacillus spp. quantified using a quantitative real-time polymerase chain reaction (qRT-PCR). 15 healthy children of ages 9 - 12 years were randomly examined. The 3 tone plaque disclosing gel was applied on teeth surfaces, which changed the color to pink or red, blue or purple and light blue. Plaque was divided into 3 groups based on staining. Genomic DNA from each sample was subjected to a qRT-PCR assay for quantitative detection of target bacteria. The Kruskal-Wallis test was conducted for correlation between the color of plaque and the number of bacterial species. The levels of S. mutans, S. sobrinus, and Lactobacillus spp. were significantly different in the plaque samples of the 3 groups (p < 0.05). The proportion of S. sobrinus to S. mutans showed correlation to the color of plaque. The different color-dyed plaque was related to the number of acidogenic bacteria. The 3 tone plaque disclosing gel could be used as one of the indicators to assess the clinical risk of caries associated with the population of S. mutans, S. sobrinus, and Lactobacillus spp.

The aim of this study was to assess the spacing and crowding of the anterior teeth in the primary dentition in Hwaseong city. Photographs of the anterior segment of 237 children satisfied the criteria. The presence of primate spaces and developmental spaces was assessed by the proximal contacts. Physiologic spacing was observed in 47.3% and 38.0% of the cases in the upper and lower arches, respectively. 43.5% showed the presence of two-segment contact or crowded dentition. Physiologic spacing was observed more in boys than in girls. In the maxilla, primate space was more frequent than developmental space; however, in the mandible, the difference was low. In the maxilla, the space between the central incisor and the lateral incisor was more frequent than the space between both central incisors. In contrast, in the mandible, the space between both central incisors was more common than the space between the central and lateral incisors or between the lateral incisors and canine. The present study describes the tendency for anterior spacing and crowding in the primary dentition. Further longitudinal studies with a larger sample are needed. Dentists should consider these concepts of spacing or contact/crowding when performing full coronal restorations of primary anterior teeth.

Objective : This study is designed to identify effect of a sensory integration(SI) program provided to elementary school students as an after-school activity. The study is looking at both occupational performance components and school-task performance which is an area of occupational performance. Methods : SI program specially designed as an after-school activity was provided to three boys who are first- or second grade students of Y elementary school in Dae-Jeon city. The SI intervention was organized with 25 sessions and carried out for two months. One group pretest-posttest design was used to evaluate the effectiveness of the SI program. Measurements used are Short Sensory Profile(SSP), K-DTVP-2, and BOTMP for occupational performance components, and School Function Assessment for functional schooltask performance. Results : It is found that posttest scores were enhanced in all assessments SSP; BOTMP; K-DTVP-2; and SFA. Conclusion : Results of this study simply propose that sensory integration program designed as after-school activity may have positive effects on not only occupational performance components but also on school-task performance of elementary school student. Since sample size is too small, however, there is limitation to find statistical significance. Further researches testing large number of subjects are required to boost the finding of this study.
