Objectives The purpose of this study was to investigate the current status of interventional clinical trial registration for children with precocious puberty and to secure basic data for the design of clinical trials for traditional Korean medicine treatment of precocious puberty. Methods The following resources were used to search for data: Clinicaltrial.gov, World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), and Clinical Research Information Service (CRIS), using the search terms, 'Precocious puberty', 'child'. All clinical trials which were registered as of June 2022 were used. Results For the intervention and clinical trial design, gonadotropin releasing hormone (GnRH) analog was reported in 41.7% of trials, and single group assignment was performed in 66.7% of the studies. Prior consent had not been reported in 50% of the studies. Tanner stage and GnRH stimulation tests were reported by multiple trials as inclusion criteria, and prior treatment experiences for trial drugs were reported as exclusion criteria. The peak serum concentration of luteinizing hormone following GnRH stimulation test was used as a primary outcome in 45.8% of clinical trials, and other growth-related indicators such as growth rate, height, and predicted adult height were also reported. Conclusions In consideration of the design, eligibility criteria, and outcome measurement of the existing clinical trials identified in this study, it should be referred to in the design of clinical trials for traditional Korean medicine treatment of precocious puberty.

Influenced by a culture that prefers non-face-to-face activity during the COVID-19 pandemic, chatbot usage is accelerating. Chatbots have been used for various purposes, not only for customer service in businesses and social conversations for fun but also for mental health. Chatbots are a platform where users can easily talk about their depressed moods because anonymity is guaranteed. However, most relevant research has been on social media data, especially Twitter data, and few studies have analyzed the commercially used chatbots data. In this study, we identified the characteristics of depressive discourse in user-chatbot interaction data by analyzing the chats, including the word 'depress,' using the topic modeling algorithm and the text-mining technique. Moreover, we compared its characteristics with those of the depressive moods in the Twitter data. Finally, we draw several design guidelines and suggest avenues for future research based on the study findings.

Purpose: This study explored the experiences of pregnant women with depressed mood participating in a group cognitive behavioral therapy (CBT) program using video communication, based on Beck's cognitive theory. Methods: The participants were six pregnant women out of 13 women who had participated in an 8-session group CBT program using video communication for women with depressed mood (Edinburgh Postnatal Depression score of ≥9). Data were collected from February 20 through March 25, 2021. In-depth individual interviews were conducted through a video conferencing platform at 1 month post-baseline. Thematic analysis was done. Results: Three themes, 10 subthemes, and 38 concepts were derived from experiences of participating in the 4-week group CBT program (twice a week). The first theme, entitled "continuing realization" had subthemes of "a negative and instable self," "a selfish judgment that excludes others," and "a strong belief in self-control." The second theme, entitled "attempt to change for restoration" had subthemes of "shift to rational thinking," "freedom from suppressed beliefs," "tolerance of other people," and "courage for self-expression." The third theme, entitled "departure for a positive life," had subthemes of "emotional healing," "faith in oneself," and "reestablishing the criteria for happiness." Conclusion: Pregnant women with depressed mood expressed that continuing realizations and attempts to change supported their transition toward a positive direction of healing. Thus, they were able to change their distorted thinking into rational thinking through CBT using video communication. These findings support the use of group CBT using video communication with pregnant women who have depressed mood.

Recent trends in sentiment analysis have been focused on applying single label classification approaches. However, when considering the fact that a review comment by one person is usually composed of several topics or aspects, it would be better to classify sentiments for those aspects respectively. This paper has two purposes. First, based on the fact that there are various aspects in one sentence, aspect mining is performed to classify the emotions by each aspect. Second, we apply the multiple label classification method to analyze two or more dependent variables (output values) at once. To prove our proposed approach's validity, online review comments about musical performances were garnered from domestic online platform, and the multi-label classification approach was applied to the dataset. Results were promising, and potentials of our proposed approach were discussed.

The purpose of this study was to devise a specific plan for activating sports to promote health in old age against the prolonged COVID-19 pandemic. Through literature review, it also analyzed the association between health status and COVID-19 in old age, suggested health promotion policies and projects for elderly people, and presented a plan for activating sport to promote health in old age against COVID-19 era. First, it is necessary to revise the relevant laws, including the Sport Promotion Act and the Elderly Welfare Act, partially or entirely, make developmental and convergent legislations for elderly health and sports, and establish an institutional device as needed. Second, it is necessary to build an integrated digital platform for the elderly and make a supporting system that links facilities, programs, information, and job creation as part of a New Deal program in the field of sports on the basis of the Korean New Deal. Third, it is necessary to train elderly welfare professionals. Efforts should be made to establish more departments related to elderly sports in universities and make it compulsory to place elderly sports instructors at elderly leisure and welfare facilities. Fourth, it is necessary to develop contents related to health in old age. This means performing diverse movements by manipulating them through a virtual reality (VR) simulation. Fifth, it is necessary to make a greater investment in research and development related to elderly sports and relevant fields. This means the need to conduct constant research on healthy and active aging in a systematic and practical way through multidisciplinary cooperation. Sixth, it is necessary to establish and operate an elderly management agency (elderly health agency) under the influence of the Office of the Prime Minister. This means the need to secure independence in implementing the functions related to health promotion in old age and make comprehensive operation, which involves all the issues of health promotion in old age, daily function maintenance and rehabilitation, social adjustment, and long-term care, by establishing an elderly management agency in an effort to give lifelong health management to the elderly and cope with the untact, New Normal age.

The existing emergency medical systems are unable to obtain accurate clinical information, so most of the specialized first aid is being done within the hospital. In this paper, designed medical information transfer structure based on medical information standards HL7 for accurate first aid is proposed. The designed system can share clinical information and emergency medical information in terms of standard HL7 messages. Therefore, the correct first aid is available in steps taken by the hospital. In addition, the system of this paper has been implemented based on the OSGi service platform for the efficient integration with other health-related services.
