Objective : The aim of this study was to find associations between specific symptoms and suicidal behavior by using global severity on depression scales. Methods : Data were obtained from 1,183 patients of CRESCEND study. Factor analysis of the 17-item Hamilton Rating Scale for Depression (HAM-D) and the Beck Depression Inventory-II (BDI-II) was used to compare symptom clusters between the past suicide attempters and the non-suicide attempters, among the patients with depressive disorders. Results : Factor analyses of HAM-D and BDI-II extracted three factors. Suicide attempters had significantly higher scores on core factor of HAM-D, including depressed mood, feeling of guilt, suicide, work, and activities. The higher scores on all factors of BDI-II or scores correlated with a total of 7 suicide attempts and with known risk factors for suicidal behavior. Conclusion : These findings suggest that the suicide attempters complained of more cognitive, affective, somatic symptoms on BDI-II, but the core factor on HAM-D was the only differentiated factor between the two groups. Clinician-rated scales as well as self-reported questionnaires were valid in measuring suicidal attempts, and the clinical profile may help in guiding the studies of biological correlates and the treatments to reduce suicide risk.

The pathogenicity to pear trees and other experimental hosts of the Apple stem grooving virus Korean isolate (ASGV-K) carried by a fungal vector, Talaromyces flavus was examined. ASGV-harboring T. flavus induced mild symptoms on virus-free pears. Symptom severity was intermediate between pears showing typical PBNLS and virus-free pears. Ten cultivars of Phaseolus vulgaris showed 35%-90% infectivity by direct infiltration into leaves and roots by ASGV-harboring T. flavus. Application of fungal cultures to soils showed 0%-70% infectivity depending on the P. vulgaris cultivar. Sap extracted from ASGV-infected Chenopodium quinoa induced similar symptoms on P. vulgaris at 25 days after inoculation. Similar symptoms were also detected on P. vulgaris which were inoculated with ASGV-harboring T.flavus. When healthy P. vulgaris leaves were challenged with sap extracted from P. vulgaris leaves infected with ASGV-harboring T. flavus, typical symptoms were observed. These data suggest that T. flavus mediates the transfer of ASGV to host plants.

Objectives Antimicrobial chemicals are used in a variety of household and personal care products. Exposure to antimicrobial household products has been hypothesized to lead to allergic diseases in children. Methods We investigated antimicrobial household product exposure and allergic symptoms in Korean children. An antimicrobial exposure (AE) score was derived. To examine the symptoms of allergic diseases (current wheeze, current rhinitis, and current eczema) in the past 12 months, we used a questionnaire based on the core module of the International Study of Asthma and Allergies in Children. Complete data for the analysis were available for 25,805 of the 35,590 (72.5%) children. Results The prevalence of current allergic diseases was as follows: wheeze, 5.6%; allergic rhinitis, 32.6%; and eczema, 17.7%. The mean (standard deviation) AE score was 14.3 (9.3) (range: 0-40). Compared with subjects with a low AE score (reference), subjects with a high AE score (fourth quartile) were more likely to have symptoms of wheezing and allergic rhinitis (adjusted odds ratio [aOR] for wheezing 1.24, 95% confidence interval [CI], 1.05-1.45, p for trend=0.24; aOR for allergic rhinitis 1.30, 95% CI, 1.20-1.40, p <0.01). Conclusions These findings suggest that frequent use of antimicrobial household products was associated with current wheeze and current allergic rhinitis.

Indoor air quality (IAQ) is recognized as a byproduct of industrialization that took place in the 20th century. The great attention to IAQ has been gained since 1980s, and led to numerous research studies that have mainly made in the developed countries. As the development of residential environment in Korea enters in the process of qualitative growth, IAQ has viewed as one of the core issues in the society, and research in relation to IAQ has been implemented until now in the fields of engineering and medical science. It is widely known that the sources and effects of indoor air pollution have been various, and IAQ research with multidisciplinary approaches is required. Nevertheless, few research embedded into a socio-behavioral approach to identifying interventive measures of residents and analyzing their choices is made. The purpose of this study is to examine the use of an interactive measure of residents in apartments that is air purification with phytoncide available in the market, and to investigate their self-reported effects of the air purifying substance on sick building syndrome symptoms. This study utilizes a field experiment design with pre-test and post-test, and the experiment is conducted in a natural field setting. A total of 87 test subjects from 32 households with already sick building syndrome are drawn via internet, and the participation is solely voluntary. The participants receive and use the air purifying substance, and are asked to use it continuously for two weeks and identify their self-reported symptoms of before- and after-use. The research findings indicate that air purification using phytoncide is effective to alleviate their symptoms in relation to sick building syndrome. Also it is noted that the participants report that the use of the air purification causes the positive impacts on their daily life. Further research is needed that compares the group with only humidifier and evaluates the mid-term and long-term use of the air purification and its effects.

The objective of this review is to establish practice parameters for pharmacological treatment of children and adolescents with pervasive developmental disorders. We performed a detailed review of the literature, including a wide range of controlled clinical trials, open trials, case reports, and side-effect profiles of related drugs. Few medications have a treatment indication for pervasive developmental disorders, and few studies with well-controlled methodology are available for evaluating treatment results. Pharmacological treatments focus on associated target symptoms because symptom reduction may improve educational and social ability and enhance quality of life. Well-controlled trials have been conducted for some SSRI(selective serotonin reuptake inhibitor) antidepressants, risperidone, and methylphenidate, and showed reduction of some target symptoms. Since the medications are not specific to autism and do not treat core symptoms of the disorder, their potential side effects should be carefully considered. Family education is necessary to give proper information on target symptoms, limitation of drug treatments, and risks.

This retrospective observational study was aimed to evaluate that Daoyin Exercise therapy improves the symptoms related to lumbar disc herniation. We analyzed the medical records of 7 patients, who satisfied with inclusion and exclusion criteria. The subjects of the study were the patients who were prescribed Daoyin Exercise Therapy and Korean medical treatments for lumbar intervertebral disc herniation at Dunsan Korean Medicine Hospital of Daejeon University from July 25th, 2016 to March 31th, 2017. The effects of Daoyin Exercise Therapy was evaluated by comparing before and after taking Daoyin Exercise Therapy through 0-10 Numeric Rating Scale(NRS), Roland & Morris Disability Questionnaire(RMDQ), Trunk Extension Flexion(TEF) Program, EuroQol five Demension Questionnaire(EQ-5D, EQVAS) of the symptoms including lower back pain. The Daoyin Exercise Therapy combined with Korean medicine treatment reduced NRS($3.357{\pm}3.038$) and RMDQ($9.50{\pm}6.364$), and improved Muscle endurance($44.429{\pm}45.136$), EQ-5D($0.09{\pm}0.12$) and EQVAS($6.571{\pm}19.260$) of the 7 patients without side effects. These results implied that Daoyin Exercise Therapy might helps to improve symptoms of patients with lumbar disc herniation by reducing the symptoms of lower back pain and improving muscle endurance, quality of life, strength enhancement and core muscles.

Purpose: The aim of this study was to develop a situation-specific theory to explain the disease management experience of patients with asthma. Methods: Twenty participants with asthma were selected using the theoretical sampling method. The data were acquired through in-depth interviews conducted from June to October 2018 and analyzed using the grounded theory approach of Strauss and Corbin. Results: In total, 69 concepts, 30 subcategories, and 13 categories were generated to explain the disease management experience of patients with asthma. The core category of the disease management experience of patients with asthma was 'management of the disease to prevent aggravation of symptoms over the lifetime'. The disease management process of asthma patients included three steps: the 'cognition phase', the 'adjustment phase', and the 'maintenance phase'. However, some patients remained in the 'stagnation phase' of disease management, which represents the result of the continual pursuit of risky health behavior. There were three types of disease management experiences among patients with asthma: 'self-managing', 'partially self-managing', and 'avoidant'. Conclusion: This study shows that patients with asthma must lead their disease management process to prevent exacerbation of their symptoms. It is imperative to develop nursing strategies and establish policies for effective disease management of patients with asthma based on their individual disease management processes and types.

It has been reported that the operative treatment for the preservation of tooth having periapical lesion has shown over ninety percent of success whereas in the case where calcified canal is severe, canal is perforated, ledge is formed, tooth restored by post and core and cases where symptoms still exist after treatment, endodontic treatment may not all be the solution in attaining a successful treatment. Thus Apicoectomy would generally be used to prevent the loss of tooth having periapical lesion where treatment prognosis is poorly evaluated by endodontic treatment. In case 1 and 2, endodontic treatment was applied due to unilocular radiolucent lesion in periapical area but the symptoms somehow did not show improvement and therefore operated apicoectomy, and as in case 1, favorable results were attained but as in case 2, yet more observation has to be done. The followings are the results we have concluded : 1. In the process of endodontic treatment, absolute canal obturation has great effect on attaining successful treatment. 2. In cases where endodontic treatment is not highly recommended, for example, tooth having dental pulp and periapical lesion, favorable results can be attained by applying apicoectomy.

Methylphenidate is a widely used stimulant for treatment of attention-deficit hyperactivity disorder (ADHD). In addition to core symptoms of attention and behavioral symptoms, methylphenidate is even effective for executive functions. However, abuse and misuse of stimulants, including methylphenidate, for the purpose of cognitive enhancement is an issue of concern worldwide. Some prejudices and misunderstandings against methylphenidate are popular ; however, little attention has been given to the neuropsychiatric evidence of methylphenidate for enhancement of cognitive function among healthy populations. In this article, our aim was to conduct a review of previous studies investigating the effect of methylphenidate in healthy populations. Findings from several recent studies have demonstrated the effectiveness of methylphenidate for enhancement of cognitive function in healthy populations. The mechanisms of cognitive enhancement are thought to be associated with motivation and the reward circuit in the brain. However, when considering the risk to benefit, an official discussion of the use of methylphenidate among healthy members of the population would be premature. Instead, investigation of epidemiological studies of the prevalence of misuse of stimulants among healthy members of the population, particularly adolescents and college students, is needed. In addition, based on achievements reported in previous studies, investigation of the effect of an approach using non-pharmacological enhancing motivation, which will in turn result in increased cognitive function would be helpful.

Due to the city concentrated symptoms, high-rise building symptoms and diversity, the scale of fire disaster is increasing. So the economic expectation of fire disaster industry is growing. The domestic fire industry has an inadequate system, and hasn't a methodical system to foster the industry. And also most of the fire industry company are small and poor scale. So they haven't enough infrastructure like technical skill, manpower, marketing and so on. In order to drive fire industry from local fire protection industry to knowledge service, in this study, the items of human resources fostering, infrastructure and R&D were set and analyzed as detailed growth analysis factors. Also, the improvement plans were suggested and compared with IT industry which is defined as core industry in the 21st century knowledge-based economy in Korea.
