Purpose: To evaluate the accuracy of a target position at static and dynamic state by using Dynamic phantom for the difference between tumor's actual movement during respiratory gated radiation therapy and skin movement measured by RPM (Real-time Position Management). Materials and Methods: It self-produced Dynamic phantom that moves two-dimensionally to measure a tumor moved by breath. After putting marker block on dynamic phantom, it analyzed the amplitude and status change depending on respiratory time setup in advance by using RPM. It places marker block on dynamic phantom based on this result, inserts Gafchromic EBT film into the target, and investigates 5 Gy respectively at static and dynamic state. And it scanned investigated Gafchromic EBT film and analyzed dose distribution by using automatic calculation. Results: As a result of an analysis of Gafchromic EBT film's radiation amount at static and dynamic state, it could be known that dose distribution involving 90% is distributed within margin of error of 3 mm. Conclusion: As a result of an analysis of dose distribution's change depending on patient's respiratory cycle during respiratory gated radiation therapy, it is expected that the treatment would be possible within recommended margin of error at ICRP 60.

During the main ruling in 2019, a number of rulings that were of interest or meaningful were handed down, such as just because the complication of medical practice has occurred, there is no presumption of negligence, a case involving a fall accident in which a lot of culpability has recently been made. the death of a well-known singer that caused a sensation, a case about damages caused by MERS in 2015, which is more meaningful in connection with damages caused by COVID-19, an infectious disease that has recently hit the world, including Korea. In preaching the principles of the law, just because there has been a complication caused by medical practice, there is no presumption of negligence, 'The scope of the complication without presumption of negligence' was determined differently by the court, the court was not able to specify the criteria. Specific circumstances were presented to limit the responsibility of the medical institution while acknowledging the malpractice of the medical institution in relation to the fall accident. In relation to the scope of damages, judgment was made on issues related to the calculation of lost profits of medical malpractice; criteria for determining celebrities' daily income, criteria for determining daily income in case of receiving survivor's pension due to medical accident, an incident in which the daily income is denied if the labor capacity is already lost at the time of a medical accident. But, it seems that judgments should be made based on clearer and more reasonable standards. Related to Medical Advertise, specific logic of judgment was presented as to whether it was interpreted as being in accordance with the specific prohibition listed in Article 27 paragraph 3 of the Medical Law, which is the criterion for violation of the Medical Law, or if it constitutes a significant harm to the order of the medical market. In response to the prohibition of operating the multiple medical institutions, the Constitutional Court decided that it was constitutional because it did not violate the regulations on excessive funding, and rationally limited the scope of the prohibited 'redundant operation'. The Supreme Court ruled for the first time that even a medical institution established and operated in violation of the Medical Service Act did not make it impossible to receive all medical care benefits implemented by a medical institution under the National Health Insurance Act. Significant rulings were finalized that recognized the existence of specific protection obligations for the people of the country in the management of infectious diseases.

Purpose: This study was conducted to identify the perception regarding palliative care among Korean doctors and referral barriers toward palliative care for terminal cancer patients. Methods: Between May and June 2010, 477 specialists mainly caring cancer patients using a web-based, self-administered questionnaire. Results: A total of 128 doctors (26.8%) responded. All respondents (100%) deemed palliative care a necessary service for terminal cancer patients. More than 80% of the respondents agreed to each of the following statements: all cancer centers should provide palliative care service (80.5%); all terminal cancer patients should receive concurrent palliative care along with anti-cancer therapies (89.1%) and caring for terminal cancer patients requires interdisciplinary approach (96.9). While more than 58% of the respondents were satisfied with their performance of physical and psychological symptoms management and emotional support provided by patient's family members, 64% of the responded answered that their general management of the end-of-life care was less than satisfactory. Doctors without prior experience in referring their patients to palliative care specialists accounted for 26.6% of the respondents. The most common barrier to hospice referral, cited by 47.7% of the respondents, was "refusal of patient or family member", followed by "lack of available palliative care resources" (46.1%). Conclusion: Although most doctors do recognize the importance of palliative care for advanced cancer patients, comprehensive and sufficient palliative medicine, including interdisciplinary cooperation and end-of-life care, has not been put into practice. Thus, more active palliative consultation or referral is needed for effective care of terminal cancer patients.

Consumers are very concerned about food safety as the risk with food increased. This study was conducted to evaluate the perceptions and practices of consumers on food safety in order to collect some information for the development of consumer education program. Total 500 consumers were asked to answer for survey constituted with 6 questions of generic information, 4 of food safety perceptions and 8 of food safety practices from June to July, 2006. More than half of respondents (51.8%) were unsatisfied with the food safety management of government while the individual practices on food safety were satisfactory. Especially, most respondents (98.7%) checked the expiration date of food when they purchased and 97% of respondents were washed hands before food preparation. The higher food safety perception, the better food safety practices of consumers. These results suggest that the systematic and continuous educations on food safety hazards and the principles of sanitation management are necessary for safe food handling and perception on food safety.

Purpose: The purpose of this study was to evaluate the quality and problems of Web sites for management of childhood and adolescent obesity. Methods: We evaluated 203 Web sites identified from the search engine, Korean Yahoo, using the word of 'childhood and adolescent obesity'. 203 Web sites were classified according to medical institutions, health information Web sites, beauty shops. etc. We surveyed whether childhood and adolescent obesity distinguished with adult obesity was considered, or not. and researched the unique managements of childhood and adolescent obesity including the cardinal treatment. Results: Of the 203 Web sites, 157(77.3%) provided detailed information about treatment of obesity, 46(22.7%) provided only simple information about one. The sites providing detailed information were composed of 52.2% of oriental medicine clinics, 35.0% of clinic & hospitals including pediatric hospitals. Distribution of the sites about management of childhood and adolescent obesity distinguished with adult's one was only 23% of oriental medicine clinics, but 93% of childrens hospitals. Conclusion: Without considering the speciality of childhood obesity, inaccurate information are distributing on internet web sites. It is necessary for concern and development of advertizing system on the internet distributing accurate information about treatment of childhood obesity.

Purpose: The purpose of the present study was to investigate needs and satisfaction on the medical services of cancer patients in Jeju Special Self-Governing Province. Methods: Total 174 cancer patients, who visited at the clinic of Jeju National University Hospital, submitted informed consent and participated in this study from July 13 to July 30, 2009. Self questionnaire was used and data were analyzed with Kolmogorov-Smirnov test, Mann-Whitney U test, ANOVA, and Kruskal-Wallis test. Results: Participants expressed the needs of most economical support (3.38 out of 4), followed by counseling of treatment plan (3.22), information of disease (3.07), and disease management except cancer (2.97). Participants were satisfied most with religious counseling (3.41), followed by nursing service support (3.39), employment counseling (3.26), and counseling for family or interpersonal relationships (3.26). The satisfaction of economical support was the lowest (1.98). Satisfaction of men was higher than women, and needs in patients who were living with children was the highest. Patients who were living alone or with children showed the lowest satisfaction about the medical services. There were no significant differences in the general characteristics, however, participants who were older than 60 years of age or had higher income showed lower needs and higher satisfaction. There were no significant differences in the medical characteristics, however, thyroid cancer patients and patients who were treated with radiation therapy or transarterial embolization showed low satisfaction. Conclusion: Cancer patients seemed to need more economical support, information of treatment or disease, and symptom management. Furthermore, there were various needs about the services, depending on family formation or economical support of patients. Therefore, it is certain that patients who were suffering from other cancers, except the 5 major cancers, needed more services. In conclusion, continuous and systemic policy to consider patient's characteristics and needs are needed in community as well as health care system.

The purpose of this study was to analyze the research trend in home economics education using network text analysis method. The 586 research articles published in the Journal of Home Economics Education Association between July, 2003 and December 2018 were examined using Neckinger 4, a social network analysis software. The frequency and centrality measures(degree centrality, closeness centrality, and betweenness centrality) were calculated for the words appeared throughout the whole period, and the centrality analysis and LAD(Latent Dirichlet Allocation) were conducted for the four sub-periods. The results are as follows: first, the most frequently appeared words are parents, culture, unit, health, career, consumption, practicality, etc. The words such as parents and management scored high in degree centrality; parents and male students in closeness centrality; and male students and units in betweenness centrality. Second, when divided into four periods, the words such as education, family, purpose, class, middle school, and school appeared most frequently across the periods; but some words such as 'purpose' (in period 3 and 4), or 'process' (in period 4) were salient only in certain periods. Third, the words with high centrality were consistent regardless of the types of centrality within each period. Fourth, the topic analysis using LAD showed that curriculum, textbook, family healthiness, teaching-learning, evaluation, dietary life, appearance management, and consumption were the topics consistently appeared across all periods. The topics have become diversified and deepened. New topics such as teacher training and safety appeared in later periods, possibly due to the curriculum and national policy changes, and housing as a less represented topic is suggested as an area that needs further research attention. This study has implication in that it allows researchers to identify the major research interests and the trends in research by researchers in home economic education.

As Pain is a comprehensive, biopsy chosocial phenomenon, improved understanding and successful management of pain need assessment of health-related quality of life and psychological states. The purpose of this study was to evaluate pain severity and pain-related interference to daily lives for patients with non-dental, orofacial pain(OFP) and a possible relation of OFP with psychological morbidity. Relation with such factors as gender, age, pain duration and diagnosis was also assessed. Inclusion criteria was all new patients with non-dental OFP attending the oral medicine.orofacial pain clinic of Dankook University Dental Hospital over 3 months' period, who completed the questionnaires of the Brief Pain Inventory (BPI) and Hospital Anxiety and Depression Scale (HADS). Prior to the first consultation, the patients were asked to fill out the questionnaire in the waiting room and were diagnosed through consultation and clinical examination. Total subjects were 163 with M:F ratio of 1:1.5 and mean age of 34.6${\pm}$17.7 years. Mean duration of pain was 13.3${\pm}$26.2 months and all patients were divided into; Trigeminal Neuralgia group (TN, N=8), Neuropathic Pain group (NeP, N=9), Persistent Idiopathic Facial Pain group (PIFP, N=8), and Temporomandibular Disorders group (TMD, N=138), subdivided into muscle problem (TMD-m, N=73), joint problem (TMD-j, N=24) and muscle-joint combined problem (TMD-c, N=41). OFP patients showed moderate pain severity and moderate pain-related interference. There was no gender difference in overall pain severity and interference and levels of anxiety and depression. Elderly patients aged ${\geq}$ 60 years showed higher pain severity (p<0.05). Patients with chronic pain ${\geq}$ 3 months reported more increased level of anxiety and depression than those with acute pain (p<0.05). Compared to TMD patients, patients with TN, NeP and PIFP suffered from higher level of pain and pain-related interference and reported higher level of anxiety and depression (p<0.05). Pain interference was closely correlated with their pain severity and with psychometric properties such as anxiety and depression. Pain severity was weakly correlated with levels of anxiety and depression. The results suggest a need for psychosocial assessment and support for successful management of OFP in addition to control of pain itself.

Green infrastructure planning represents landscape planning measures to reduce particulate matter. This study aimed to derive factors that may be used in planning green infrastructure for particulate matter reduction using text mining techniques. A range of analyses were carried out by focusing on keywords such as 'particulate matter reduction plan' and 'green infrastructure planning elements'. The analyses included Term Frequency-Inverse Document Frequency (TF-IDF) analysis, centrality analysis, related word analysis, and topic modeling analysis. These analyses were carried out via text mining by collecting information on previous related research, policy reports, and laws. Initially, TF-IDF analysis results were used to classify major keywords relating to particulate matter and green infrastructure into three groups: (1) environmental issues (e.g., particulate matter, environment, carbon, and atmosphere), target spaces (e.g., urban, park, and local green space), and application methods (e.g., analysis, planning, evaluation, development, ecological aspect, policy management, technology, and resilience). Second, the centrality analysis results were found to be similar to those of TF-IDF; it was confirmed that the central connectors to the major keywords were 'Green New Deal' and 'Vacant land'. The results from the analysis of related words verified that planning green infrastructure for particulate matter reduction required planning forests and ventilation corridors. Additionally, moisture must be considered for microclimate control. It was also confirmed that utilizing vacant space, establishing mixed forests, introducing particulate matter reduction technology, and understanding the system may be important for the effective planning of green infrastructure. Topic analysis was used to classify the planning elements of green infrastructure based on ecological, technological, and social functions. The planning elements of ecological function were classified into morphological (e.g., urban forest, green space, wall greening) and functional aspects (e.g., climate control, carbon storage and absorption, provision of habitats, and biodiversity for wildlife). The planning elements of technical function were classified into various themes, including the disaster prevention functions of green infrastructure, buffer effects, stormwater management, water purification, and energy reduction. The planning elements of the social function were classified into themes such as community function, improving the health of users, and scenery improvement. These results suggest that green infrastructure planning for particulate matter reduction requires approaches related to key concepts, such as resilience and sustainability. In particular, there is a need to apply green infrastructure planning elements in order to reduce exposure to particulate matter.

The purpose of this study is to present raw data to systematically and rationally manage the protected trees located in Changwon-si, Korea. This study investigated about the present condition and the information of location, individual, management, health and soil. The results are as follows. The protected trees were located in 26 spots, and species of trees were 9 taxa; Zelkova serrata, Celtis sinensis, Aphananthe aspera, Ginkgo biloba, Carpinus tschonoskii, Pinus densiflora for. multicaulis, Quercus variabilis, Pinus densiflora and Salix glandulosa. In protected tree types, shade trees were the most, and the majority of theirs were 200 years or more in age. The range of altitude was 14~173m, and the number of trees located in flat fields was the most. For location types, village and field and mountain were presented in the order and, in land use, land for building was the most. The range of height was 8.0~30.0m, 0.6~5.1m in crown height, 240~700cm in diameter of breast and 210~800cm in diameter of root. In case of crown area, Zelkova serrata of No.5 was most large. The status boards were mostly installed except No.23 and No.26. The sites with fence were 9 spots, and the site with stonework were 14 spots. The sites with the support beam were 5 spots, and most sites were not covered up with soil. The materials of bottom were soil, gravel and vegetation in the order. The range of withering branch rate was 0~40%, and peeled bark rate was 0~60%. The sites made holes were 23 spots, and the hole size of Aphananthe aspera of No.12 was the largest. The sites disturbed by human trampling were 7 spots, the sites by disease and insects of 2 spots, the sites by injury of 23 spots and the sites by exposed roots of 13 spots. In the results of soil analysis, there showed that acidity was pH 4.5~8.0, organic matter content of 3.5~69.8g/kg, electrical conductivity(EC) of 0.11~2.87dS/m, available $P_2O_5$ of 3.0~490.6mg/kg, exchangeable K of 0.10~1.05cmol+/kg, exchangeable Ca of 1.41~16.45cmol+/kg, exchangeable Mg of 0.37~1.96cmol+/kg, exchangeable Na of 0.25~2.41cmol+/kg and cation exchange capacity(C.E.C) of 8.35~26.55cmol+/kg.
