This study examined the effects of group social support on the reduction of burden and increase in well-being of mothers of developmentally delayed children. The research used a one group pre-pose experimental design. The independent variable in the experiment was group social support. Two series of 4-weekly meetings for group social support were conducted by the researcher with the intention of developing a self-help group. The dependent variables were burden and well-being. Well-being was operationalized as physical symptoms and quality of life. Thirty mothers of developmentally delayed infants from the rehabilitation center of a medical center participated in the study. Data were collected by interviews and a self-administered questionnaire. The mean age of the subjects was 29.9 years. Changes of the dependent variables between pre and post tests were compared using the t-test. Even though there was a slight improvement in the scores for the dependent variables, they were not statistically significant. The items, "I resent my baby". "I feel angry about my interactions with my baby", "I feel guilty in my relationship with my baby" showed a significant decrease in burden score and were statistically significant. Symptoms of loneliness, constipation, anxiety, restlessness were less and feeling of happiness was greater after participation in the group social support, than on the pretest. The mothers showed emotional instability and frustrations during the group sessions but their reactions in general were positive. Emotional support, stress management and information provided were identified as the most valuable content of the sessions. However, participation was not active due to the mother's denial, delayed acceptance and /or avoidance of their infants' problems. It can be seen that group social support for the mothers with developmentally delayed children should be provided after infancy when the mothers have time to accept their children's conditions and are ready to receive support. The use of comprehensive instruments which measure burden in both families and mothers needs to be developed for future research.

Pathogen infection in plants induces complex responses ranging from gene expression to metabolic processes in infected plants. In spite of many studies on biotic stress-related changes in host plants, little is known about the metabolic and phenotypic responses of the host plants to Pseudomonas cichorii infection based on image-based analysis. To investigate alterations in tomato plants according to disease severity, we inoculated plants with different cell densities of P. cichorii using dipping and syringe infiltration methods. High-dose inocula (${\geq}10^6cfu/ml$) induced evident necrotic lesions within one day that corresponded to bacterial growth in the infected tissues. Among the chlorophyll fluorescence parameters analyzed, changes in quantum yield of PSII (${\Phi}PSII$) and non-photochemical quenching (NPQ) preceded the appearance of visible symptoms, but maximum quantum efficiency of PSII ($F_v/F_m$) was altered well after symptom development. Visible/near infrared and chlorophyll fluorescence hyperspectral images detected changes before symptom appearance at low-density inoculation. The results of this study indicate that the P. cichorii infection severity can be detected by chlorophyll fluorescence assay and hyperspectral images prior to the onset of visible symptoms, indicating the feasibility of early detection of diseases. However, to detect disease development by hyperspectral imaging, more detailed protocols and analyses are necessary. Taken together, change in chlorophyll fluorescence is a good parameter for early detection of P. cichorii infection in tomato plants. In addition, image-based visualization of infection severity before visual damage appearance will contribute to effective management of plant diseases.

In order to investigate the complaint rates of subjective fatigue symptoms and study the relationship between them and body type, health awareness in middle school students, we carried out a survey of 1,209 students (654 boy students and 555 girl students) at a middle school in Taejon City by a self-recorded questionnaire. The survey was conducted in June, 1997. The results obtained were as follows: 1. Among complaints of fatigue, "feel like lying down" was the highest, followed by "feel anxious about things", "feel drowsy", "yawning a lot", "eye strain" and "whole body feels tired" in descending order. 2. In the average weighted score of fatigue complaint, dullness and sleepiness (I) was the highest, followed by a difficulty in concentration (II) and bodily projection of fatigue (III) in descending order. Fatigue seems to create mental stress rather than physical burdens. 3. In the classification of body type based on the $R\ddot{o}hrer$ index, the obesity type (145 and above) was 11.0%, standard type (110~144) was 64.7% and leptosomic type (l09 and below) was 24.3%. Comparison between both sexes revealed that the rate of obesity and leptosomic types were significantly higher in boy students than in girl students. 4. In terms body type awareness, the statistics are the following: those who consider themselves to be standard type, 44.3%, slightly obese 24.5%, leptosomic, 23.5% and obese 7.8%. However, the level of obesity awareness was significantly higher in girl students than in boy students. 5. As for health awareness, 36.5% considered themselves healthy, 5.4% generally healthy and 10.1% a little unhealthy, but the level of unhealthy awareness was higher in girl students than in boy students. 6. In the relationship between body type and health awareness, most students thought that they were obese in spite of their standard body type. Also, many students who were obese and leptosomic tended to consider themselves to be a little unhealthy. 7. The more the students were obese or felt unhealthy, the more the average weighted score of fatigue complaints was high.

Objectives: The purpose of the study was to examine the influencing factors of oral health-related quality of life in adults. Methods: A self-reported questionnaire was completed by 300 adults in Seoul and Gyeonggido from June to July, 2015 by convenience sampling method. Except 19 incomplete answers, 281 data were analyzed by t test, one way ANOVA, Pearson's correlation coefficient analysis, and multiple linear regression analysis using SPSS 18.0 program. The questionnaire consisted of general characteristics of the subjects, health-related characteristics, whole body dry symptoms and subjective perception of dry mouth. The oral health-related quality of life was measured by Likert five points scale, and a higher score indicated a lower quality of life. Results: The oral health-related quality of life in adult varied by age, systemic diseases, oral health status, missing tooth, stress, decayed tooth, gingival disease. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The subjective perception of dry mouth(${\beta}$=0.245) had the influence on the oral health-related quality of life, oral health status(${\beta}$=-0.209), gingival disease(${\beta}$=-0.151), and decayed tooth(${\beta}$=-0.146) in order. Conclusions: The oral health-related quality of life was closely related to the subjective perception of dry mouth and the oral health status. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the adults.

This study is designed to evaluate the clinical implications of Gd-DPTA (Gadolinium-diethyl enetriamine pentacetic acid) enhanced MRI(Magnetic resonance imaging) in Bell's palsy and find it's usefulness in Oriental Medicine In this study, 25 outparients with Bell's palsy were studied that MRI was performed. To evaluate degree of facial palsy, H-B(House-Brackmann) Grade was used. In Oriental Medical therapy, Acupuncture and Herbal medicine were treated. Subjective cause was divided into exposure to chill, fatigue, stress, mixed cases. Enhanced site was compared with symptoms which were disorder of eye, hearing, taste, and facial muscle palsy. Also, Relation between time which was performed MRI and enhancement was analyzed. The enhanced lesion in MRI was divided into five segments; Internal audiitory canal, Labyrinthine segment, Geniculate ganglion, Tympanic segment, Mastoid segment. In Bell's palsy, 20 of 25 patients(80%) had abnormal contrast enhancement of the facial nerve. The H-B grade and interval performed MRI from onset were directly proportionate to enhancement. That is to say, Severe facial palsy short interval show high possibility of enhancement. There was no relation between subjective causes and enhanced site of facial nerve in MRI. Also Clinical symptoms didn't coincide with MRI findings.

Objective: The objective of this study was to evaluate a work of guards, using an ergonomic method(work analysis and posture analysis). Background: Most studies about guards were conducted in the field of medical, problems of shift, and the physical problems of old workers and social problems. But, guards consist of vulnerability group so it needs an ergonomic research in musculoskeletal disorders. Method: A head of an ergonomic estimation was work analysis(determination of combined task, work tool, work time and frequency of combined task) and posture analysis(upper body and lower body) of workers based on the video. Results: The result showed that combined task of guards was classification of patrolling, security, cleaning and waiting. The security indicated the highest ratio in the work time of combined tasks. The results of posture analysis for guards indicated high value in neutral. But, lower arm indicated high value in bending(left: 59%, right: 50%). Conclusion: The results of ergonomic methods indicated that guards' physical work load was not high during work, but comfortable work environment would be required for old guards. Application: If an ergonomic rule can be integrated into existing work environments, the risk of occupational injuries and stress will be reduced.

Xu-lao(虛勞) is deficient disease which is weak body and spirit. It occurs many symptoms, for example lack of appetite, dizziness, involuntary emission of semen, wet dream, back and chest pain, night sweat, cough and so on. In oriental medicine, xu-lao(虛勞) is well-known disease and can be treated easily. In general, xu-lao (虛勞) patiences like to be treated by oriental medical doctors. In spite of improving food, house and clothes, xu-lao(虛勞) is on the increase by fatty foods and stress. In most of these cases, the cooperations of heart and kidney are hurted. On Fang-you-ge-bian(脈證方藥合編) which is the famous prescription book in Korea, gu-an-xin-shen-wan(古庵心腎丸) and Jiu-yuan-xin-shen-wan(究原心腎丸) are used well and have good effects in these cases. Gu-an-xin-shen-wan(古庵心腎丸) can treat white hair, palpitation, involuntary emission of semen, amblyopia, buzzing in the ears, backache and so on. Jiu-yuan-xin-shen-wan(究原心腎丸) can treat lack of appetite, dizziness, involuntary emission of semen, wet dream, back and chest pain, diseased sweat, cough, coldness of hands and feet, and so on. The symptoms of Gu-an-xin-shen-wan(古庵心腎丸) are similar with those of Jiu-yuan-xin-shen-wan(究原心腎丸). But, it is very important that Gu-an-xin-shen-wan(古庵心腎丸) can be used in cases of hot deficient disease but Jiu-yuan-xin-shen-wan(究原心腎丸) can be used in cases of cold deficient disease.

Safety at sea continues to be an important topic for research. The factors that contribute to safety issues are often complex and unclear. Lack of non-technical skills in such areas as communication, teamworking, situational awareness, decision making etc. are well documented as directly affecting safety in high risk work settings such as on board merchant vessels. Competence in non-technical skills can be affected by various habits and circumstances that influence a worker and result in either positive thinking and behaviour or negative thinking and behaviour. Negative thinking can cause stress, anger, frustration; loneliness etc. and this can possibly result in behaviour or actions that undermine the safety of crew and ship. Factors that may contribute to these negative thoughts and behaviours are many and varied and this paper will be looking at one aspect: mobile phone use. In the Republic of Korea, dependency on mobile phones is uniquely high. Maritime students are also susceptible to such dependency and this paper will demonstrate that the symptoms associated with mobile phone addiction and dependency, and in particular the symptoms of withdrawal, are important factors that need to be mitigated in order to improve safety at sea. Although the benefits of mobile phones are many it will be suggested that over-reliance, dependency or addiction can result in negative thinking or behaviour that may directly or indirectly contribute to the factors that cause incidents and accidents at sea. It will be suggested that the most appropriate method of dealing with this problem is twofold: firstly, through training at the educational level and secondly, by encouraging the shipping industry and government to invest more into providing seafarers with better access to the communication methods that they are used to on shore in order to improve work conditions.

Purpose: This study was a systematic review and meta-analysis to explore the factors related to quality of life in heart transplant recipients. Methods: To identify studies that suggested the factors related to the quality of life in heart transplant recipients, we searched the articles published from 1974 to November 2018 using Six databases, PubMed, CINAHL, EMBASE, Cochrane, KMBASE and RISS. A total of 22 studies were selected out of 5,234 for the systematic review and meta-analysis on the basis of the PRISMA flow. The quality of study was assessed by assessment tool form the NIH and meta-analysis was performed using the 'R 3.5.2' version to analyze the correlated effect sizes. Results: Factors related to quality of life in heart transplant recipients were categorized into six domains based on the health-related quality of life model introduced by Ferrans: individual, environmental, biological function, symptoms, functional status, and general health perception. In the meta-analysis, 34 factors were used and 17 factors having significant effect sizes were as follows: self-efficacy, demoralization, perceived control, current occupational status, age, marital status, health promotion life style in the individual characteristics; stress in environmental characteristics; physical function status, creatinine level, left ventricular ejection fraction (LVEF) in biological function; anxiety, depression, symptom frequency and distress in symptoms domain; coping, self-care compliance in functional status. Conclusion: The findings indicate that the multi-dimensional factors influencing the quality of life in heart transplant recipients and provide the evidence for developing effective interventions for improving the quality of life of recipients.

This study was carried out among 34 patients who visited Yonsei Dental Hospital from 1996. 1. to 1999. 5 for trigeminal neuralgia. By studying the patient's treatment prior to visiting our hospital, features of trigeminal neuralgia, treatment process of trigeminal neuralgia, prognosis of treatment, consultation with other professions and involvement of surgery, etc., the results are as follows: 1. 67.7% of onset age range from 40s to 60s, and average age is 50.2. 2. Ratio of right to left involvement is 1:2.1, male to female ratio is 1:1.9. 3. Occurrence rate of each branch is V3(44.1%), V2(11.8%), V1+V2+V3(11.8), V1+V2(8.8%). 4. Treatments prior to admission to our hospital are extraction(5.9%), endodontic treatment(5.9%), medication(11.8%), Oriental Medicine treatment(5.9%). 5. Routes of admittance to our hospital are by their preference(55.9%), local clinic referral(32.4%), E.N.T referral(5.9%), Neurology referral(5.9%). 6. 70.6% of patients treated at our hospital who were relieved of symptoms, were referred to Neurology(66.7%) and Pain Clinic(33.3%) for the reason of relapse, side effects of the drug itself, incomplete relief of pain. 7. 2 patients who were referred to medical part showed brain vessels contacting trigeminal nerve root on Brain MRangiography. But pain is being controlled by medication and no specific surgical procedure was carried out. The results show that 17.7% of patients admitted received inappropriate early treatment. In order to relieve tooth loss and patient's psychologic stress due to inappropriate treatment, precise differential diagnosis must be made among local teeth disease and idiopathic facial pain. Medication may show side effects of the drug itself, incomplete relief of pain or relapse of symptoms. Therefore, to treat trigeminal neuralgia appropriately by drug injection, surgery or radiation therapy, consultations among dentists, neurologists and anesthesiologists are required.
