Many industries are being severely damaged by COVID-19, a respiratory infection that has recently been prevalent around the world. In particular, for workers in the construction industry, it is impossible to work from home, and if an outbreak on a construction site is confirmed, it can lead to great damage. Accordingly, the government has drafted 「Guidelines for Response to Construction Sites for Prevention and Spread of COVID-19」. In addition, domestic and foreign research about COVID-19 in the field of construction sites is being actively conducted. However, Korea has lacked studies on the effectiveness of the countermeasures in place at construction sites, or that reflect the opinions of construction site workers. Therefore, this study conducted a survey of construction site workers by dividing the construction of the COVID-19 quarantine management system and response plan into on-site management and social management. Through the AHP/IPA analysis, it was found that among social management, 'infectious disease management system and cooperation system with related institutions' and 'reduction of working hours' are areas with high importance but low satisfaction. After that, the causes of the two items were analyzed and related countermeasures were suggested. The results of this study will be able to contribute to the improvement of the quarantine management system and response plan at construction sites, and to minimize the damage to the construction industry related to COVID-19.

Dental surgical procedures are potentially stress-inducing to not only patients but clinicians especially in case of medically compromised patients. The body response to dental stress involves the cardiovascular, respiratory and the endocrine system. To minimize the stress to the medically compromised patients, the stress reduction protocols should be established. The protocols include (1) Recognize the patient's degree of medical risk (2) Medical consultation before dental therapy (3) Schedule the patient's appointment in the morning (4) Monitor and record preoperative, perioperative and postoperative vital signs (5) Intra-venous sedation during surgical procedures (6) Adequate pain control during therapy (7) Short length of appointment time (8) Contact the patients on the same day. Two cases of Bisphosphonate-related osteonecrosis of the jaws were analyzed. There were 2 women, and the mean age was 70 years (range, 64~74 years). both are medically compromised, with steroids. Both patients were taking an oral bisphosphonate for several years. BRONJ is defined as an area of exposed bone of more than 8 weeks - duration in a patient taking a bisphosphonate for bone disease. Bisphosphonates have been widely prescribed over the last decade for a range of bone diseases, mainly intravenously for bone cancers and orally for osteoporosis. Although it is still controversial as to precisely how the bisphosphonates work, generally it is accepted that they prevent osteoclast action, with consequent cessation of osteoblast activity, so that the bone turnover is markedly reduced or ceased. The aim of this study is to informed the clinicians how to prepare and recognize in case of the BRONJ with medically compromised patients.

This work discussed the species composition, phylogeny, spatio-temporal distribution, ecology and natural history of North Korean Pinaceae or pine tree family, which seems to be important to maintain nature and ecosystem in the Korean Peninsula. Out of five genera and sixteen species of Pinaceae of the Korean Peninsula, North Korea contains four genera and eleven species of Pinaceae, including Pinus densilflora, P. koraiensis, P. pumila, Picea jezoensis, P. koraiensis, P. koraiensis var. koraiensis, P. pungsanensis, Larix gmelini, L. gmelinii var. olgensis, Abies holophylla and A. nephrolepis. In terms of phylogeny Pinus is closely related to Picea, and followed by Larix. Abies is close to Tsuga which only occur at Ullung Island. Distributional pattern of North Korean Pinaceae can be classified into four types; three species of nation-wide montane type i.e., Pinus densilflora, P. koraiensis and Abies holophylla, four species of central and northern subalpine type, i.e., Pinus pumila, Picea koraiensis, Larix gmelini and Abies nephrolepis, one nation-wide subalpine type, Picea jezoensis, and three species disjunctive to north type, i.e., Picea koraiensis var. koraiensis, P. pungsanensis, and Larix gmelinii var. olgensis. Pinaceae species occurring on the alpine and subalpine belts of North Korea, such as Pinus koraiensis, P. pumila, Picea jezoensis, P. koraiensis, P. koraiensis var. koraiensis, P. pungsanensis, Larix gmelini, L. gmelinii var. olgensis and A. nephrolepis are considered as the glacial descendant from the boreal region. Those species might have migrated from the north during the Pleistocene glacial epochs in search of favourable condition, and since the Holocene period they survived on the hostile alpine and subalpine environments, in which they are more competitive than warmth-tolerant temperate vegetation. Certain species, such as Picea pungsanensis, is segregated on the isolated mountains since the Pleistocene period, and forced to adapt to local environment, and eventually became an endemic species of North Korea. Recent rapid global warming trend especially in northern high mountains of North Korea could cause an unfavourable environment for the survival of cold-tolerant Pinaceae of the alpine and subalpine belts. Pinus densiflora, which is occurring on the montane belt might faced with difficulties due to both the deforestation and the outbreak of insect-borne disease, such as Bursaphelenchus xylophilus.

Lesion mimic mutant (LMM) plants display spontaneous necrotic lesions on their leaves without any pathogenic infection. Specific rice LMMs designated as spotted leaf (spl) including spl1, spl3, spl4, spl5 and spl6 are genetically known as lesion resembling disease (lrd) mutant. The inheritance patterns in the $F_1$ and $F_2$ progenies of these mutants are controlled by recessive genetic factors. Lesion development in the rice LMMs were controlled by both development stages and environmental factors. The rice LMMs exhibited higher numbers of spots under $45^{\circ}C$ temperature than those under $30^{\circ}C$. Contents of chlorophyll were drastically reduced at 60 days old LMM leaves when the spot formation was severe. The levels of endogenous hydrogen peroxide were highest at 45 days old mutants but reduced at 60 days old. Transcription levels of stress related genes including thioredoxin peroxidase and protein disulfide isomerase were reduced in spotted leaves than those of non spotted leaves. It could be suggested that scavenging system against reactive oxygen species induced by either stresses or innate metabolisms may not work properly in the rice LMMs. As these rice LMMs autonomously expressed clear lesions of lrd phenotype without pathogen infection, it could be useful to understand stresses responses in plants.

The purpose of this study was to examine the recognition level related to the infection prevention in dental medical institute in dental hygienists and to offer basic data of enhancing the knowledge education in dental hygienists on the infection prevention according to it. As a result of collecting and analyzing data by using the self-administered questionnaire on April 27, 2008 targeting 230 dental hygienists who are working at hospitals and clinics in P,K region, the following conclusions were obtained. 1. Dental hygienists' recognition on hospital-virus treatment method was indicated to be averagely 1.20 out of 3-point perfection. 2. The recognition on infection was indicated to be averagely 2.64 out of 4-point perfection. The statistically significant difference was shown with the appearance of periodical health examination(t=-2.42, p<.05) and by infection-education experience(t=2.28, p<0.05). 3. The recognition on an infection disease was indicated to be averagely 4.38 out of 8-point perfection. The significant difference(t=3.52, p<0.05) was shown depending on task in charge. 4. The recognition on the infection prevention in dental treatment institute was indicated to be averagely 4.89 out of 7-point perfection. The recognition on the infection prevention of dental treatment institute in dental hygienists, who work for general hospital, was indicated to be the highest. Accordingly, it was considered to be required an effort for dental hygienists, other dental-medical practitioners, and patients to be able to treated safely by enhancing the recognition level on infection prevention in dental hygienists and by maximally reducing exposure to infection in dental medical institute.

Penicillium expansum causes blue mold rot, a prevalent postharvest disease of pome fruit, and is also the main producer of the patulin. However, knowledge on the molecular mechanisms involved in this pathogen-host interaction remains largely unknown. In this work, a two-dimensional gel electrophoresis-based proteomic approach was applied to probe changes in P. expansum 3.3703 cultivated in apple juice medium, which was used to mimic the in planta condition. The results showed that the pH value and reducing sugar content in the apple juice medium decreased whereas the patulin content increased with the growing of P. expansum. A total of 28 protein spots that were up-regulated in P. expansum when grown in apple juice medium were identified. Functional categorization revealed that the identified proteins were mainly related to carbohydrate metabolism, secondary metabolism, protein biosynthesis or degradation, and redox homeostasis. Remarkably, several induced proteins, including glucose dehydrogenase, galactose oxidase, and FAD-binding monooxygenase, which might be responsible for the observed medium acidification and patulin production, were also detected. Overall, the experimental results provide a comprehensive interpretation of the physiological and proteomic responses of P. expansum to the host plant environment, and future functional characterization of the identified proteins will deepen our understanding of fungi-host interactions.

This study was carried out to introduce the Foot reflexo-massage (FRM) as a method of nursing practice based on the health promotion of occupational health. Literature reviews were done to achieve study aims from October in 1999 to August in 2000. The results were as follow ; 1. Theory of the FRM was mainly developed from the reflexology based on function and role of foot. 2. The FRM is focused on the appropriate reflexology of foot with pressures of light-moderate-light or light-strong-light scaled strength for 15 minutes at each feet. The massage should begin with the foot area where it is assumed as a was, of internal to external and upper to lower side. It also should start from left to light side of the feet. 3. The FRM is an alternative therapy increasingly demanded as an self applying method between eastern and western due to the benefit of natural healing power with no side effects. 4. The FRM can be an nursing intervention for health promotion of employees through supportive and educative nursing system in occupational health service. As a conclusion of the study, it suggested that the FRM can be recommended as a nursing intervention to promote health of employees and to prevent disease related to work.
