Background: Irritable bowel syndrome (IBS) is a digestive disorder characterized by abdominal discomfort or pain accompanied by a change in stool condition. Owing to its complicated mechanisms, a standard treatment for IBS has not yet been established. Yukgunja-tang (YGT) is a Korean herbal medicine known in Asia to be effective in the treatment of gastrointestinal symptoms. In this study, we will conduct a systematic review of randomized controlled trials (RCTs) to assess the efficacy and safety of YGT in IBS treatment. Methods and analysis: English databases, such as Embase, Medline (via PubMed), Allied and Complementary Medicine Database, and Cochrane Central Register of Controlled Trials, will be searched for articles published up to April 2023. Additional databases, such as five Korean, one Chinese, and one Japanese database, will be included. RCTs and quasi-RCTs will also be included in the assessment of the efficacy of YGT. The overall efficacy rate will be the primary outcome, and data such as IBS quality-of-life measurements, global symptom scores, and adverse events will be the secondary outcomes. Review Manager Version 5.3 will be used for evaluation, and the risk of bias (RoB) will be evaluated using Cochrane Collaboration's RoB tool. The Grading of Recommendations Assessment, Development, and Evaluation approach will be used to score the quality of evidence. Conclusion: This study will demonstrate the efficacy and safety of YGT for treating patients with IBS.

Objective：This study was designed to investigate the difference between executive function of Attention Deficit/Hyperactivity Disorder(ADHD) group and that of neurotics, and to investigate the developmental aspects of ADHD group's executive function. Method：Executive function between ADHD(N=87) and Neurotics(N=19) was evaluated through their performance on the Wisconsin Card Sorting Test. The results were analyzed by 2-way ANOVA and t-test. Results：The results revealed group difference between ADHD and neurotics in total correct reponses, total error responses, nonperseverative errors, number of categories completed, conceptual level responses. There was no significant difference between the performance of 8-12 aged group and 13-15 aged group. But 7-8 aged group showed significantly poor performance than 8-12 aged in total responses, total error responses, perseverative responses, perseverative error responses, nonperseverative error responses. Conclusions：In comparison to the neurotics group, the children of ADHD group are suggested to be lacking the ability to correct their responses according to the external feedback and they probably respond randomly without self-control. However, as there is no difference between perseverative errors and perseverative responses, the interpretation of this finding warrants caution. It also suggests that the developmental aspects should be considered in the studies of executive functions because there are differences in the performance of executive functions by ages.

Objective : The purpose of this study was to conduct biomechanical analysis of varying backpack loads on the lower limb movements during downhill walking over $-20^{\circ}$ ramp. Method : Thirteen male university students (age: $23.5{\pm}2.1yrs$, height: $175.7{\pm}4.6cm$, weight: $651.9{\pm}55.5N$) who have no musculoskeletal disorder were recruited as the subjects. Each subject walked over $20^{\circ}$ ramp with four different backpack weights (0%, 10%, 20% and 30% of body weight) in random order at a speed of $1.0{\pm}0.1m/s$. Five digital camcorders and two force plates were used to obtain 3-d data and kinetics of the lower extremity. For each trial being analyzed, five critical instants were identified from the video recordings. Ground reaction force, loading rate, decay rate, and resultant joint moment of the ankle and the knee were determined by the inverse dynamics analysis. For each dependent variable, one-way ANOVA with repeated measures was used to determine whether there were significant differences among four different backpack weight conditions (p<.05). When a significant difference was found, post hoc analyses were performed using the contrast procedure. Results : The results of this study showed that the medio-lateral GRFs at RHC in 20% and 30% body weight were significantly greater than the corresponding value in 0% of body weight. A consistent increase in the vertical GRFs as backpack loads increased was observed. The valgus joint movement of the knee at RTO in 30% body weight was significantly greater than the corresponding values in 0% and 10% body weight. The increased valgus moment of 30% body weight observed in this phase was associated with decelerating and stabilizing effects on the knee joint. The results also showed that the extension and valgus joint moments of the knee were systematically affected by the backpack load during downhill walking. Conclusion : Since downhill walking while carrying heavy external loads in a backpack may lead to excessive knee joint moment, damage can occur to the joint structures such as joint capsule and ligaments. Therefore, excessive repetitions of downhill walking should be avoided if the lower extremity is subjected to abnormally high levels of load over an extended period of time.

The "Annals of the Joseon Dynasty (朝鮮王朝實錄)" is the precious historical material which contains royal culture of Joseon dynasty as an official document. It kept a record of the diseases and treatments relating to the 27 Kings for a period of 518 years, who had a variety of different symptoms. Among them the most frequent disease was a skin disorder such as a boil of a painful infected swelling. Dermatosis became the direct cause of death of several Kings. In this article we tried to conduct research using the "Annals of the Joseon Dynasty" into the skin diseases of the Kings during the first period of Joseon dynasty from the first King Taejo (太祖) to the 12th King Injong (仁宗). Among the 12 Kings, the 5th King Munjong (文宗), the 7th King Sejo (世祖), the 9th King Seongjong(成宗), the 10th King Yeonsangun (燕山君), and the 11th King Jungjong suffered from dermatosis. The King Munjong died at the age of 38 and suffered from severe boils before his death. The cause of death is thought to be septicaemia. The King Sejo does not have any specific record of skin disease, however, the recently discovered relics showed the indications of serious skin trouble of boils. The King Seongjong suffered from skin diseases at the age of 20, 27, 28 and 38. Nevertheless, the direct cause of death was not dermatosis. The King Yeonsangun had skin trouble of boils on his face when he was 20. He lost the throne and died of an infectious disease at 31. The King Jungjong had a record of suffering from dermatosis at the beginning of twenties, at the middle of forties, and at the age of 57 when he died. The skin trouble affected the whole of the body. He was treated with acupuncture therapy and medication for both internal and external uses among which folk remedies were included.

Objectives : This study aimed to evaluate the clinical usefulness of Korean version of Strengths and Difficulties Questionnaire(SDQ-Kr) by comparing with Korean version of Childhood Behavior Checklist (K-CBCL). Methods : The parent version of SDQ-Kr and K-CBCL were administered to parents of 313 children in psychiatric clinic, 91 children referred for psychiatric consultation from pediatric clinic and 93 control children in pediatric clinic. All children aged 4-11 years old. Children in psychiatric clinic were diagnosed with one of followings;ADHD, emotional disorders and oppositional/conduct disorder. Mean scores were compared among three groups by gender. Coefficients were calculated for corresponding problem scales and total scores of both questionnaires. ROC analysis was performed for discriminant validity to distinguish psychiatry and pediatrics samples, and also to distinguish diagnostic groups of psychiatry sample. Results : The psychiatry sample showed highest means of problem scales and total scores, followed by consultation and control sample of pediatrics. SDQ-Kr and K-CBCL were significantly correlated, and equally able to distinguish those samples with SDQ-Kr showing better results. Within the psychiatry sample, SDQ-Kr had higher predictive power for all diagnostic groups. Conclusion : This study supports clinical usefulness of SDQ-Kr. We suggest that SDQ-Kr could be used not only as a diagnostic tool for children in psychiatric clinic but also as an effective and efficient screening instrument for children in need for psychiatric evaluation in pediatric clinic.

This study investigated the characteristics and factors affecting inpatient infants, children, and adolescents who experienced falling, using NHDIS data from 2008 through 2017, The study analyzed data of 116 patients who were under 18 and who experienced injuries (KSCD, S00-S99) by falling (KSCD, W00-W19). Frequency analysis, cross-tabulations, and multiple regression analysis were conducted, using SPSS 23. There were more boys than girls, and most of the falls occurred at the ages of over one to under six years old. Most of the children had respiratory diseases, and most had open wounds or bruises due to falling. Also, most of the falls were related to the bed. In the factor analysis, age (β=.318), the main diagnosis (β=.231), and injury (β=.169) except gender affected falling. This suggests that it is necessary to conduct fall prevention education for children, considering the developmental stage characteristics and age group. It is necessary to screen the risk group such as children with a disease with relatively less restriction of activities or with a hyperactive disorder, and to develop a related manual. Hopefully, the results will be used as the basic data for fall prevention education and creating a fall prevention manual according to the characteristics of children's developmental stage for patients who need hospitalization, their caregivers, and the relevant medical team.

Objective：This study was performed to identify and understand the characteristics of adolescents who had a history of police arrest and/or were adjudicated unruly/delinquent by the juvenile court. Method：The study employed a retrospective reivew of coumputer-recorded data set on 210 consecutive admissions to an adolescent psychiatric inpatient unit. Three groups(No Police Contact, N=115；Police Contact Only, N=60；Adjudicated, N=35) were compared on the areas of a) cognitive and educational performance b) emotion：anxiety, depression, suicidality c) personality d) family and life experiences. Standardized assessments were administered to all subjects using WISC-Ⅲ, Kaufman Test of Educational Achievement, Millon Adolescent Personality Inventory, Reynolds Adolescent Depression Scale, Revised-Chilren’s Manifest Anxiety Scale, Suicide Ideation Questionnarie, Suicide Behavior Interive, Life Events Checklist, and Family Environmental Scale. A subgroup of the subjects, 60 cases also received a standardized interview by Child Assessment Schedule. Results：The characteristic findings of the delinquent group(the police contact only and adjudicated subjects combined) included (1) a high rate of adoption, sexual promiscuity, out of home placement, and repeated psychiatric hospitalization, (2) low verbal IQ scores and educational achievements, (3) high impulsivity, low social conformity, and high forcefulness in personality inventory, (4) low activityrecreation orientation and low moral religious emphasis in family environment, (5)a high frequency of adverse life experiences, (6) among 3 groups, the Police Contact Only group showed the lowest depression, anxiety and suicidal ideation scores, (7) a high diagnostic frequency of conduct disorder, ODD, and ADHD. Conclusions：The adolescent psychiatric inpatients with a delinquent history presented with a certain clinical, family, psychometric characteristics that warrant specific clinical intervention strategies for their cognitive deficits, an impulsive personality style, family dysfunction with adverse life experiences and disruptive behavioral disorders, different from the rest of adolescent psychiatric inpatients.

The purpose of this study is to introduce the Levying Garage Option on Car Buyers which has become operative firstly in Korea, and to suggest the way to activate the system, hearing the view of Jeju residents with positive and negative function of parking. Levying Garage Option on Car Buyer is the system to apply a law for establishing garages to all of vehicles. Especially this is proposed to correct the disorder of Local street night parking, to improve the fine view of street, and to recover the original function of street to residents. To make this system successful there should be separate solutions at the densely built up area as a result of survey. This study conduct the Logistic Regression Analysis for and against the system. If the more residents approve the system, we should concern about the several solutions such as easing the distance between the garage and street, regulating, and special plan for an apartment house, etc. The suggestions are as follows. First, the policy needs to ease the distance between the garage and street gradually. Second, the Jeju government need to offer the residents the incentive such as reduce or exempt the tax and make them establish the private parking lot with supplying the low interest loan. Third, there should be connected with the project to break up the fences of their houses.

TMJ Osteoarthritis is a degenerative disease caused by overload on joint tissue, and often accompany with local tenderness on the joint, crepitus by mandibular movement, restriction of mandibular movement, and anterior openbite. In general, panoramic radiography, TMJ panoramic radiography, and transcranial radiography are conducted to diagnose osteoarthritis after clinical examination, however, these radiographic evaluations are limited in detecting minute bony changes of early pathologic lesion. The aim of this pilot study was to evaluate the limitation and usefulness of several TMJ imaging techniques, so we compare the findings from clinical examination, plain film radiographs, tomograph, and bone scan from 81 patients with temporomandibular joint disorder. The proportion of patients showing same findings in plain film radiographs, TMJ tomograph, and bone scan was high, however, it is desirable that clinician should conduct phased imaging examinations according to the clinical findings due to the possibilities of false negative findings in diagnosis of osteoarthritis.
