The number of depressed patients in Korea and around the world is rapidly increasing every year. However, most of the mentally ill patients are not aware that they are suffering from the disease, so adequate treatment is not being performed. If depressive symptoms are neglected, it can lead to suicide, anxiety, and other psychological problems. Therefore, early detection and treatment of depression are very important in improving mental health. To improve this problem, this study presented a deep learning-based depression tendency model using Korean social media text. After collecting data from Naver KonwledgeiN, Naver Blog, Hidoc, and Twitter, DSM-5 major depressive disorder diagnosis criteria were used to classify and annotate classes according to the number of depressive symptoms. Afterwards, TF-IDF analysis and simultaneous word analysis were performed to examine the characteristics of each class of the corpus constructed. In addition, word embedding, dictionary-based sentiment analysis, and LDA topic modeling were performed to generate a depression tendency classification model using various text features. Through this, the embedded text, sentiment score, and topic number for each document were calculated and used as text features. As a result, it was confirmed that the highest accuracy rate of 83.28% was achieved when the depression tendency was classified based on the KorBERT algorithm by combining both the emotional score and the topic of the document with the embedded text. This study establishes a classification model for Korean depression trends with improved performance using various text features, and detects potential depressive patients early among Korean online community users, enabling rapid treatment and prevention, thereby enabling the mental health of Korean society. It is significant in that it can help in promotion.

A safety management rule of the diagnosis radiation system which opened a court 2006 February 10th was promulgated for safety of the radiation worker, patients and patients' family members. The purpose of this study is to minimize injury by radiation that can happen to patients and people around a sick ward when managing mobile X-ray system. This study analyzed sickroom environment of mobile X-ray examination and the statistical data of the Konkuk medical Information System(KIS) and the Picture Archiving Communication System(PACS). This study also investigated patient conditions, infection, relation information and related data, when the sickroom mobile X-ray examination is used. Through data analysis, many problems were expected such as restriction of space side, manpower and expense of business side, satisfaction degree decline of patient and protector of operation side. Therefore, we tried to restrict examination of multi bed sickroom, and to use treatment room in each ward to solve problem mentioned. As a result, the whole sickroom mobile X-ray examination rate decreased to near 50%, and mobile X-ray examination rate for inpatients decreased to more than 85%. This study shows that several attempts we did should be helpful for manpower, patients satisfaction and expenses. Also, they should protect patients in sickroom from unnecessary radiation exposure and could minimize inconvenience of patients and their family members from x-ray examination.

Background: In contrast to a healthy person, patients who have acute lower respiratory tract infection with underlying pulmonary diseases have various pathogens, a rapidly progressive downhill course, and a poor response to prior antimicrobial therapy. Broad spectrum antibacterial therapy is needed for full evaluation. Materials and Methods: To evaluate the efficacy and safety of cefpirome, we administered 1gm cefpirome, twice a day to 30 patients, who had signs and symptoms of acute lower respiratory infection regardless of their underlying disease, except to those who had an allergic history to antibiotics or severe systemic diseases. Results: The results were as follows: 1) Among 30 cases, 21 cases(70.0%) showed excellent improvement, and 7 cases(23.3%) showed good improvement in their symptoms and signs of acute lower respiratory infection. 2) In 14 cases with isolated pathogens, we observed bacteriologic eradication in 11 cases(78. 6%). 3) Significant side effects were not found. Conclusion: Above results suggest that cefpirome was effective as a monotherapy in patients with acute lower respiratory infection, especially on those with an underlying chronic obstructive pulmonary disease(COPD).

The incidence of childhood cancer is greatest in the first year of life. Early diagnosis and advances in medicine have significantly improved outcomes of treatment resulting in higher survival rate; however, this progress comes at the expense of a higher incidence of adverse side effects because of more aggressive antineoplastic treatment strategies. The oral cavity, a trauma-prone environment, is extremely sensitive to toxicities from antineoplastic agents. Oral health care specialists, including pediatric and hospital dentists can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment, and assisting and/or managing oral complications from cancer therapy. This article covers the considerations in the dental management of pediatric patients undergoing cancer treatment, specifically chemotherapy, radiotherapy, and hematopoietic stem cell transplantation.

Due to the COVID-19 pandemic, non-face-to-face treatment was temporarily permitted. A lot of consensus has been formed on the need to continuous non-face-to-face treatment. However, the current 「Medical Service Act」 only permits telemedicine between doctors and medical personnel. On the other hand, as a result of legal interpretation, there is an opinion that non-face-to-face treatment is allowed. But considering the overall legal system, non-face-to-face treatment is not allowed. Nevertheless, we have to consider the reality such as the development of science and technology and the outbreak of infectious diseases. Therefore, it is not advisable to allow face-to-face treatment only. Ultimately, it is necessary to find ways to ensure that non-foce-to-face treatment can be performed in a safe and effective manner. And it should be institutionalized. This is strategically necessary and important. Therefore, we must look over ahead legal issues to be discussed. First of all, the scope, the target disease and the subject of implement have to be clear. Also, structurally, the standards of facilities and equipment must be prepared for non-face-to-face treatment to be implemented. Functionally, communication and information exchange between doctors and patients should be well conducted. In addition, the information protection management system that occurs in the process of non-face-to-face treatment should be materialized. Lastly, the issue of responsibility and cost of non-face-to-face treatment should be decided in detail. When these problems materialize, it can be expected that a safe non-face-to-face treatment environment will be established.

Objectives : The purpose of this study was to investigate the various aspects of stress in patients with chronic prostatitis. Methods : Thirty two chronic prostatitis patients meeting the criteria of NIH-category III were compared with sixty four controls. Data pertaining to the source of, response to, and coping with stress, as well as chronic prostatitis symptom index were collected using a self-report questionnaire. The questionnaire consisted of a Global Assessment of Recent Stress(GARS), Stress Response Inventory(SRI), Ways of Coping Checklist(WCC), in addition to the NIH-CPSI. Results : From the results of GARS subscales, the scores of changes in relationship, sickness or injury and financial were significantly higher in patients with chronic prostatitis than normal controls. Chronic prostatitis patients had greater amplification of somatization, depression and anger in SRI and significantly lower score in ways of coping checklist compared with controls. In the NIH-CPSI of chronic prostatitis patients, the degree of symptom played a role in depression as stress response item and significant negative correlationship between the symptom point and problem focused, seeking social support coping strategy was observed. Conclusion : These results show that patients with chronic prostatitis have greater stress, higher stress response and insufficient coping strategy. Therefore, these efforts should be considered that enhancing healthier coping strategy and evaluation and management of stress experienced by chronic protatitis patients

Fibromyalgia is a disorder characterized by the core symptom of chronic widespread pain, along with fatigue, sleep disturbances, mood changes, and cognitive difficulties. The etiology of fibromyalgia involves a combination of biological factors, such as genetic vulnerability, alterations in pain processing and stress response system ; psychological factors, such as anxiety, depression, anger, and perceived stress ; environmental factors, such as infections, febrile diseases, and trauma. Central sensitization, which is amplified in the process of sensory stimulation, has been emphasized as a key etiological factor, as supported by enhanced wind-up, delayed aftersensation, decreased nociceptive flexion reflex threshold and functional imaging studies. Several guidelines recommend that a multimodal approach be used to treat fibromyalgia, including both pharmacological and non-pharmacological treatments, tailored to each individual, and that clinicians should provide an intellectual framework through sufficient education and emphasis on the importance of self-management. The prevalence of mood disorders, anxiety disorders, and other psychiatric problems is 7-9 times higher in patients with fibromyalgia than in the general population ; moreover, the association between fibromyalgia and certain psychopathologies or sleep problems has also been suggested. Since psychiatric problems, with shared vulnerabilities and risk factors, interact with fibromyalgia bidirectionally and also affect the disease course, an integrated management approach is needed to determine the risk of comorbidities.
