The existing studies of VDT syndrome have been researched only about for nurse groups without radiological technologists. The target of this study was workers who perform VDT task in general hospital placed in Daejun City such as insurance judgement, patient affairs, medical record management, medical computing service, hospital administration, and radiological sections. This study was conducted at October 15, 2009 to November 2, 2009 using structured questionnaire. Results of group A (age 20-29, less than 5 years experience at clinical site, normal staff, and unmarried group) showed significant skin and psychological conditions among recognition symptoms of VDT syndrome. Group B (age 30-39, 6-10 years experience at clinical site, managing staff, and married group) tends to be similar at orbital, whole body and muscles' frame response among recognition symptoms of VDT syndrome. Results of "Multiple Linear Regression" with dependent variable that is scores of recognition symptoms of VDT syndrome are as follows. The factors which influences for orbital-related problem is gender, health cares and obstacles during daily life. The factors which influences for whole body-related is exercise, stress and recognition for health condition and the factors which influences muscles' frame-related is 6-10 years experience at clinical site, human relationship, health cares and obstacles during daily life. These are proved to be similar by statistic analysis. There is small difference at recognition symptom of VDT syndrome between the radiological technologist and other groups in general hospital. Yet, as the working circumstance of radiological technologist gradually changes to VDT environment, the recognition symptom of VDT syndrome became conscious. This can be prevented by regular job rotation, which will escape the continuous repetition of working pattern.

This study was conducted to understand the research trends and central concepts of middle-aged women' health in Korea. For the analysis of this study, target papers published from 2012 to 2021 were collected by entering the keywords of 'middle-aged woman' or 'menopausal woman'. 1,116 papers were used for analysis. The co-occurrence network of key words was developed and analyzed, and the research trends were analyzed through topic modeling of the LSD by dividing it into five-year units (2012-2016, 2017-2021), and visualized word cloud and sociogram were used. The keywords that appeared the most during the last 10 years were obesity, depression, body composition, stress, and menopause symptom. Five topics analyzed in the thesis data for 5 years from 2012 to 2016 were 'postmenopausal self-efficacy and satisfaction enhancement strategy', 'exercise to manage obesity and risk factors', 'intervention for obesity and stress', 'promotion of happiness and life management' and 'menopausal depression and quality of life' were confirmed. Five topics of research conducted for the next five years (2017-2021) were 'menopausal depression and quality of life', 'management of obesity and cardiovascular risk factors', 'life experience as a middle-aged woman', and 'life satisfaction and psychological well-being' and 'menopausal symptom relief strategy'. Through the results, the trend of research topics related to middle-aged women's health over the past 10 years have been identified, and research on health of middle-aged women that reflects the trend of the future should be continued.

Objectives : Although subclinical depression symptoms are associated with suicidal idea, most research have focused on clinical depression such as major depressive disorder or dysthymia. The aim of this study is to investigate network structure of depressive symptom and to reveal which symptoms are associated with suicidal ideation. Methods : We used part of data from the seventh Korea National Health and Nutrition Examination Survey. Participants were between 19 and 65 years of age (N=8,741). Network analysis with Isingfit model is used to reveal network structure of depressive symptoms and most central symptom and edges assessed by patient health questionnaire (PHQ-9). Results : The most two central symptoms were psychomotor activity and suicidal ideation. The strongest edge was psychomotor activity-suicidal ideation. Suicidal ideation also has strong association with depressive mood and worthlessness. Conclusions : These results suggest that psychomotor activity and suicidal ideation can serve as treatment target for subclinical depression and psychomotor activity, worthlessness and depressed mood may be important factor for early intervention of suicidal ideation.
Objectives: Asthma is a chronic disease, and the demand for herbal medicines in this field has increased in recent years. The new findings highlight the role of the gut-lung axis in the pathophysiology of asthma. Hence, this study will evaluate the safety and efficacy of Glasthma syrup, an herbal formula based on Persian medicine, in improving asthma and regulating intestinal permeability. The formula consists of five herbal ingredients that have anti-inflammatory effects on the respiratory tract, also known as gut tonics. Methods: The study will be conducted as a placebo-controlled, triple-blind, randomized trial. It will consist of a 4-week intervention followed by a 4-week follow-up period. The target sample size is 20 patients with moderate asthma aged 18 to 60 years. Eligible participants will be randomly assigned to either the experimental group or the control group in equal numbers. Patients in the experimental group will take Glasthma syrup (7.5 mL, twice a day), while patients in the control group will take a matching placebo. Both groups will receive a 4-week combination of a long-acting beta2 agonist and a leukotriene modulator as standard of care. Inhaled corticosteroids can be used as rescue medication as needed. Results: The primary outcomes are asthma symptom scale, lung function, and intestinal permeability. Secondary outcomes include quality of life, symptom recurrence rates, and blood tests. A safety assessment will also be conducted during the trial. Conclusion: In this trial, the effects of Glasthma syrup in patients with moderate asthma will be examined. The study will also assess the effects of the formulation on the gut-lung axis by simultaneously monitoring the gut permeability index, asthma symptoms, and lung function.
Objectives The objective of this study is to investigate the application of Sifeng point (EX-UE 10) in children and to make suggestions for domestic research and clinical application by reviewing relevant randomized controlled trials. Methods Eight electronic databases including English, Chinese, Korean databases were comprehensively searched for randomized controlled trials evaluating the effects of Sifeng point in children up to May 2, 2018. We extracted the year of publication, country, target diseases or symptoms, location of Sifeng, acupuncture method; such as acupuncture tool and depth of insertion, and frequency, number, and duration of the treatment. Results Fifty studies were included for analysis. All the included studies were conducted in China, and studies were published from 1962 to 2017. The most frequent target symptom was anorexia (46%). In addition, Sifeng point was used for digestive diseases or symptoms such as diarrhea, constipation, and mesenteric lymphadenitis, as well as respiratory diseases or symptoms such as cough, cold, acute bronchiolitis, recurrent respiratory tract infections, bronchopneumonia, and asthmatic bronchitis. Also, allergic diseases such as chronic urticaria, and other variety of symptoms such as malnutrition, fever, and iron-deficiency anemia were treated with the Sifeng point. The location of Sifeng points was inconsistent, and the most common location of the Sifeng point was the midpoint of transverse creases of the proximal interphalangeal joints of the index, middle, ring and little fingers (84.2%). The most commonly used acupuncture tool was three-edged needle (40.9%). All included studies have the method of squeezing out blood or mucus from the Sifeng points. The treatment was mostly conducted once per week (35.4%), mostly repeated for 4 times (32.6%). The most common treatment duration was 4 weeks (18.6%). Conclusions We could identify acupuncture method and various indications for the Sifeng points treatment. Based on this study, there is a need for the clinical application and related researches on the Sifeng points in children in Korea. In addition, the treatment location of Sifeng point should be standardized.
The authors performed this preliminary study to investigate the effect of softening E.C.T. and propofol was compared to pentothal for induction of anaesthesia for E.C.T. on seizure duration. The results were follows ; 1) E.C.T. was performed in 60 psychiatric inpatients who were admitted during the study period. Of them 51.7% were diagnosed as schizophrenia, 21.6% as major depressive disorder, 16.7% as bipolar I disorder, manic and 10% of others. 2) Mean number of E.C.T. was 12.2 times a patient. 3) The most common target symptoms were persecutory delusion in schizophrenia, psychomotor retardation or agitation in major depressive disorder, and violent aggressive behavior in bipolar I disorder, manic. 4) Pre-ECT medication usually used were atropine $0.0093mgkg^{-1}$, pentothal $2.76mgkg^{-1}$ or propofol $1.42mgkg^{-1}$. 5) The duration of seizure, as measured clinically, was reduced with propofol(20.5 sec) in comparison with pentothal (35.7 sec)(p<0.001). This suggests the possibility that additional treatments may be needed for the same clinical effect in psychiatric illness when propofol is used as the induction agent.
Background: This study aimed to develop a biocontrol system for ginseng root rot caused by Fusarium cf. incarnatum. Methods: In total, 392 bacteria isolated from ginseng roots and various soils were screened for their antifungal activity against the fungal pathogen, and a bacterial isolate (B2-5) was selected as a promising candidate for the biocontrol because of the strong antagonistic activity of the bacterial cell suspension and culture filtrate against pathogen. Results: The bacterial isolate B2-5 displayed an enhanced inhibitory activity against the pathogen mycelial growth with a temperature increase to $25^{\circ}C$, produced no pectinase (related to root rotting) an no critical rot symptoms at low [$10^6$ colony-forming units (CFU)/mL] and high ($10^8CFU/mL$) inoculum concentrations. In pot experiments, pretreatment with the bacterial isolate in the presumed optimal time for disease control reduced disease severity significantly with a higher control efficacy at an inoculum concentration of $10^6CFU/mL$ than at $10^8CFU/mL$. The establishment and colonization ability of the bacterial isolates on the ginseng rhizosphere appeared to be higher when both the bacterial isolate and the pathogen were coinoculated than when the bacterial isolate was inoculated alone, suggesting its target-oriented biocontrol activity against the pathogen. Scanning electron microscopy showed that the pathogen hyphae were twisted and shriveled by the bacterial treatment, which may be a symptom of direct damage by antifungal substances. Conclusion: All of these results suggest that the bacterial isolate has good potential as a microbial agent for the biocontrol of the ginseng root rot caused by F. cf. incarnatum.
Objective: This study aims to investigate subjects in recuperation to identify the following factors with regard to work-related musculoskeletal diseases: diagnosis in the context of occupational and environmental medicine; assessment systems for judging work-relatedness; recuperation management; workplace management; prevention programs; and care after returning to work. This study intends to analyze differences between subjects and determine what characteristics of subjects account for the differences. Method: A survey was administered to 1,664 workers who were approved by the Korea Worker's Compensation & Welfare Service between 2003 and 2005 for recuperation due to work-related musculoskeletal diseases. The data of 229 subjects who responded the survey questionnaire related to recuperation were analysed. Results: According to the results, demographic, occupational, and musculoskeletal disease-related factors were significant. The demographic factors included gender, age, marital status, and region, while occupational factors included working period, work type, size of workplace, and industry type. The factors related to musculoskeletal diseases were the part of the body in pain, the tissues in pain, and the existence of dysfunction. The above factors were associated with statistically significant differences in the following areas: revealed symptom period, symptoms-diagnosis period, and application for recuperation approval periods; diagnosis and care institutes for recuperarion; the state of patients (body parts in pain, tissues in pain, and existence of dysfunction); return to work; and care after returning to work. Conclusion: The results of this study can serve as basic data in setting priorities for prevention programs for work-related musculoskeletal diseases and selecting target groups.
Three-day-old sunfower(Helianthus annuus L.) seedlings were do-rooted and incubated in the nutrient solutions that contained either deficient or sufficient boron supply, and exposure to various pH and temperatures. In the absence of boron, no adventitious roots were formed in the majority of the seedlings. Boron caused the development of numerous adventitious roots in the lower part of the hypocotyl. The low pH damage was ameliorated by the simultaneous application of calcium, implying the involvement of calcium-requiring process in overcoming proton toxicity. Borate showed a strong ameliorative effect with $Ca^{2+}$. These results suggest that the primary target of proton toxicity may be linked to a disturbance of the stability in the pectic polysaccharide network, where calcium plays a key role in plant roots. Maximum temperature for the growth of adventitious roots was $25^{\circ}C$. Although cessation of growth is the most apparent symptom of boron deficiency, exogenous ascorbate improved adventitious root growth in plants in the absence of boron. From the results it is suggested that the inhibition of adventitious root resulting from boron deficiency, low pH and temperature damage may be a consequence of disrupted ascorbate metabolism.

Objectives : Schizophrenia manifests a variety of interindividual differences in therapeutic response to antipsychotics. This might be attributable to dopamine and serotonin receptors that a important target for various antipsychotics, and the $D_3$ receptor(DRD3) alleles they carry. The purpose of our study was to investigate whether the plasma levels of homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(HIAA), and the polymorphism of DRD3 can be held as a predictor of treatment response in chronic schizophrenic patients. Methods : Therapeutic response for 116 korean schizophrenia patient treated during 48 weeks were assessed by PANSS used as the clinical symptom rating scales. The levels of concentration of HVA and 5-HIAA were examined by HPLC at baseline and at 48 weeks. We classified the polymorphism of DRD3 receptor using amplifying by polymerase chain reaction(PCR). Results : Neither concentrations of HVA and 5-HIAA nor genotype of dopamine 3 receptor were not significantly associated with the therapeutic response. But, the patients who has A1 alleles of DRD3 gene showed poor therapeutic responses. Conclusion : A1 allele of DRD3 gene is associated with poor prognosis of chronic schizophrenia.
