An outbreak of new disease with leaf and stem blight symptom occurred at bracken-growing fields in Namhae-gun, Gyeongsangnam-do, Korea during the last 4 years. This new disease caused significant yield losses on bracken production in this area. We have collected diseased leaves and stems showing the blight symptom in May, July, and October 2018 to investigate causal pathogens. A total of 92 fungal isolates were obtained from the diseased samples and their pathogenicity was tested on healthy bracken leaves. From the total isolates, 22 isolates were able to produce the leaf blight symptom similar to the original one found in the fields. To identify two fungal pathogens which showed higher virulence levels compared to other pathogenic isolates, we constructed phylogenetic trees using the nucleotide sequences of genes for ribosomal RNA, RNA polymerase beta subunit, beta tubulin, and internal transcribed region. Most phylogenetic trees constructed indicate that both isolates, which are identical to each other, reside in a clade of the genus Didymella and possibly similar to D. rumicicola or D. acetosellae. Nevertheless, the exact identification of these pathogens at the species level needs further investigations. This is the first report of a blight disease on bracken by Didymella sp.

Background: Breast cancer is the most common cancer among women in most countries of the world. It is ranked first in females in Morocco (accounting for 33.4% of the total cancer burden) and more than 60% of cases are diagnosed at stage III or IV. During the last decade, health-related quality of life (HRQOL) has become an important aspect of breast cancer treatment. The objective of this study was to describe self-reported HRQOL in patients with breast cancer and to investigate its associations with sociodemographic and clinical variables. Methods: A prospective study was carried out in the main oncology centers in Morocco. Quality of life was measured using the Moroccan Arabic versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C 30 (EORTC QLQ C30) and the Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). Statistical analyses were performed using descriptive statistics and multivariate analyses. Results: A total of 1463 subjects were included in the study, with a mean age of 55.6 (SD. 11.2) years, 70% being married. The majority had stage II (45.9%) and a few cases stage IV (12.9%) lesions. The participants' global health mean score was 68.5 and in "functional scales", social functioning scored the highest (Mean 86.2 (SD=22.7)). The most distressing symptom on the symptom scale was financial difficulties (Mean 63.2 (SD=38.2)). Using the disease specific tool, it was found that future perspective scored the lowest (Mean 40.5 (SD=37.3)). On the symptom scale, arm symptoms scored the highest (Mean 23.6 (SD=21.6)). Significant mean differences were noted for many functional and symptom scales. Conclusion: Our results emphasized that the general HRQOL for our study population is lower than for corresponding populations in other countries. This study provided baseline information on the quality of life for a large sample of Moroccan women diagnosed with breast cancer.

The present investigation was initiated to find out the possible insect vector of the paulownia witches'-broom virus disease. 1. Among a number of piercing-sucking mouth type insects that were feeding on the witches'-broom infected Paulownia leaves, the tobacco leaf bug, Cyrtopeltis tenuis REUTER, was most abundant. Eggs, nymphs and adults of Cyrtopeltis tenuis were observed from the mid-August through the end of October. 2. It was found that Paulownia witches'-broom virus is transmitted by Cyrotopeltis tenuis. 3. On young Pnulownia plants, first symptom appeared twenty days after exposure to virus-bearing colonies of Cyrtopeltis tenuis. Forty days after exposure to these viruliferous insects, the characteristic symptom of Paulownia witches'-broom was apparent. 4. Paulownia witches' -broom virus was also transmitted by Cyrtopeltis tenuis to calendula and morning glory. No app"rent symptom was observed from tomato, carrot. aster, zinnia, cosmos, soybean and plantago at least until sixty days after exposure to the viruliferous colonies of Cyrtopeltis tenuis. 5. Calendula and morning glory appear to be highly suitable test plants for Paulownia witches'-broom vims because of their relatively short incubation period and distinct symptom appearance.

Purpose: The aim of this study is to investigate the characteristics of patients and teeth referred to a university dental hospital for endodontic problem. Materials and Methods: From January, 2017 to December, 2018, patients who were referred to a university dental hospital for endodontic problem were collected from clinical records. A total of 1171 patient records were analyzed. The status of the referred teeth was divided into three groups according to whether they were treated endodontically based on radiographs and clinical records at the time of referred visit. Results: 69.9% of the referred teeth were maxillary and mandibular first and second molars. The average time from referral to actual visit is 9.03 days and 65.6% of the case referred with referring letter. The most primary reasons of referral were persistent clinical symptom (pain, swelling, and sinus tract) (37.9%), diagnosis difficulty (16.7%), blockage of canal space (13.8%) and difficult tooth anatomy (11.4%). In the case of referral before endodontic treatment, the most primary reason of referral was failure to make a proper diagnosis. If the teeth were referred in the middle of endodontic treatment, the most primary reason of referral was persistent clinical symptom and blockage of canal space. In the case of referral after root canal filling, the most primary reason of referral was persistent clinical symptom. Conclusion: In the case of molars, the rate of persistent clinical symptom and blockage of canal space were the most primary reason of referral, and the rate of apical surgery and management of trauma was high in the case of anterior teeth.

This study aims to investigate the mental health level of the elderly people living alone and examine the difference in mental health level by socio-demographic factors and analyze the factors impacting on mental health level. The study subjects were 131 elderly people living alone who lived in "G" city. Symptom Check List-90-Revision(SCL-90-R) was used to measure mental health level. The results of this study were as follows. First, the study subjects' mental health level(3.53, 5 rating scale) was very severe and this means the mental health level of elderly people living alone is more severe than the mental health level of general elderly people. The study subjects showed depression symptom most seriously and also had severe somatization symptom. Second, there was significant difference in mental health level by gender and education level among socio-demographic factors. Third, in the final regression model, statistically significant factors impacting on the mental health level of the elderly people living alone were life satisfaction, ADL, IADL, welfare service support, informal support, contact frequency with children, duration of living alone, subjective state of economy. And comprehensive(macro and micro) implications were recommended.

The purpose of this descriptive correlational study was to define the relationship between the experience of Sanhuujori, Korean traditional non-professional postpartal care after delivery and abortion and present health status of chronic arthritis female patient who visited to outpatient clinic of rheumatic internal medicine at a hospital located in Seoul, Korea. A convenience sample of 64 women who orally agreed to be a participant and data were collected form October 1996 to May, 1997 for sis months by way of interview with semistructured questionnaire. The data were analyzed by the SPSS pc program using t-test, ANOVA and Scheffe test as a post hoc and Pearson Correlation Coefficient. The results of the study were as follows ; Mean age of participants was 53.2 years and mean number of children was 3.1. Mean frequency of abortion was 2.1 times per woman. Seventy four percentage of respondents did not have Sanhujori after abortion. The mean period of Sanhujori after delivery was 17.7, 15.2, 13.8 days from the first child to third child and shorter than that of general woman such as 20.0, 19.0, 17.3 days in the previous study. On the subjective evaluation of whether the women did Sanhujori well or not, the rate of 'did Sanhujori wrongly' was the highest rank in each child where as general woman 'did Sanhujori well' at the first child, 'moderate' at the second and third child and 'did Sanhujori wrongly' at the 4th and fifth child. The health status implies both subjective health status women perceived and the rate of complaints of physical symptom distress women are experiencing presently. The respondents of 82.5% perceived them as unhealthy or sick and 68.9% of women complained more than two symptoms. Mean number of physical symptom distress women complained was 2.33. The main sites of physical symptom distress were upper & lower extremities 69.1% including knee and hand, whole body 19.1%, neck 3.7%, waist & shoulders 2.7% respectively. The characteristics of the symptoms were mostly pain 60%, swelling 19.8%, rigidity & deformity 7.9% respectively, sensation of heat 6.8% and weakness 1.7%. Women perceived the etiology of the chronic arthritis as stress 25.8%, 'did Sanhujori wrongly' & overwork 23.4% respectively, genetic 12.9%, malnutrition, 4.8%, and aging process 3.2%. There were significant positive correlation between subjective health status and the period of Sanhujori after delivery of the second child(r=-0.22) and negative correlation with the number of child at the level of 5% of significance statistically(r=0.27). There were significant negative correlation between the rate of complaints of physical symptom distress and the subjective evaluation whether she did Sanhujori well or not at the level of 5% of significance statistically(r=-0.23). And the rate of complaints of physical symptom distress in the group of women who experienced abortion was significantly higher than that of women who did not experience it at the level of 5% significance statistically(t=2.00) In conclusion, this finding reconfirmed the possible relationship between health status of chronic arthritis female patient and the experience of Sanhujori after delivery & abortion. It provides a challenge to the professional care givers to research further on the effects of Sanhujori on the health status, health recovery after abortion or delivery from the various aspects through the crosssectional and longitudinal research for the refinement of the reality of not only as cultural phenomenon but as conceptual model for the appropriateness of intervention and quality of care for desirable health outcomes.

Background: It has been some controversy about the interpretation of the sentence including 'Youngin Eunhyung' that was listed in the classic, Dongeui bogam (first published 1610). The purpose of this study is to demonstrate another assumption to interpretate the meaning of 'Youngin Eunhyung' in the sentence. Methods and Results: It was identified that the quotation of the original text of the sentence. The original text was Zhenglei bencao (Categorized Pharmacopoeia) (First edition in 1082) by Tang Shenwei and Shiliao bencao (Pharmacopoeia for Healing through Nutrition). (First edition in 721-739) by Meng Shen. It was found that there were the missing of five chinese characters in the sentence of Dongeui bogam, that it meant that 'to get rid of the watery pus in the anterior chamber of eyeball'. So, I understand that the meaning of the sentence is related with one of the ophthalmologic disease. All the evidence supports this assumption, including the mystery of another sentence of the 'blue dog'. Conclusions: It is concluded that the treatment using in Dongeui bogam that means to alleviate the symptom of obstruction or indistinction of the vision field was caused by hypopyon. However, further scientific research is warranted to provide to support this opinion.

In April 2014, seedlings of Fallopia multiflora showing wilt symptom were first found at a greenhouse in Punggi-eup, Yeongju-si, Korea. A Fusarium-like fungus was isolated from the wilted plant and it was identified as Fusarium oxysporum based on morphological characteristics and nucleotide sequence data of translation elongation factor 1-${\alpha}$. The fungus isolated from the diseased plant was revealed to be pathogenic to the host plant through pathogenicity tests, and the reisolation of the pathogen confirmed Koch's postulates. This is the first report of Fusarium wilt occurring on Fallopia multiflora in the world.

Objective: The purposes of this study are to investigate ergonomic problems and to propose their improving measures in office environment of big general hospitals. Background: Office tasks have varying risk factors of work-related musculoskeletal disorders (WMSDs). The first symptom resulted from the office work was recognized as an occupational disease in Korea in 1986. Although the symptoms have increased since its first recognition, there has been few study on the effect of office work environment settings. Method: First, the author took pictures of working scenes performed in three big university hospitals. Next, the pictures were analyzed in view point of ergonomics. Based on the analysis, their improving measures were proposed for reducing work stress. Results: The results showed that most physical office environment settings such as dimensions of tables/desks and chairs, leg room, thigh, knee and foot clearances, and chairs used did not satisfy the ergonomically recommended design guidelines. In addition, some clerks placed personal belongings under their desks, put monitors in high position and did not lean against the backrest of chairs in seated tasks, which resulted in poor working postures of leg, back, neck etc. It is recommended that the hospital management should provide their clerks with ergonomically designed office furniture and continuously perform ergonomics training program for raising clerks' recognition for office ergonomics. Conclusion: Most office environment settings investigated in this study were not in good condition in view point of ergonomic design for the settings. Application: It would be useful as basic data for establishing ergonomically good office environment in hospitals.

The purpose of EMS is to provide emergency patients with prompt and suitable emergency treatments therefore it saves their lives and makes them recover fast to return to normal. The purpose of correctional administration is to return inmates to society as sound citizens after their service by providing various correctional education, reformational programs, vocational training and etc. In this way, the aim of correctional administration and EMS is like mutual agreement by their returning to society safely. Therefore this study makes some propositions like the followings for the safety between many inmates who can have physical injury and exposure to diseases caused by particularity of subculture within correctional institutions and the staffs who work for them. It is said about efficient pre-hospital EMS through various causes of emergency situation in the correctional institution, system, manpower, facility, equipments and problems and so on. 1. Recruit the first-rate EMT(emergency medical technician) as central role of pre-hospital EMS according to each correctional institution and working terms. 2. Equip specialized transference system with symptom of patients and purpose of transference. 3. Emergency medical equipments and first-aid medicines should be equipped for field and ambulance. 4. Educate correctional officers as first responders and inmates within correctional institutions about systematic emergency treatment.
