Objectives: This study was aimed to develop a Korean Medicine (KM) clinical practice guideline (CPG) of Nausea and Vomiting of Pregnancy (NVP). Methods: We conducted a questionnaire survey targeting KM doctors belonging to the Association of Korean Medicine by e-mail. We received 1,023 responds, and analyzed the answers. Results: 1. 83.0% of respondents knew the concepts and contents of CPG, and 98.1% had practical use plan. 2. 82.1% of respondents used pattern identification diagnosis for NVP patients, and the most commonly diagnosed pattern was spleen-stomach weakness (脾胃虛弱) with 41.3%. 3. The most frequently used treatment for NVP patients was KM combined treatment (46.7%). Herbal medicine+acupuncture (46.8%) was most used among KM combined treatments, and herbal medicine (37.1%) was most used among KM single treatments. 4. Among the contents of CPG for NVP, the fields of interest were selected in the order of KM treatment, KM-Western medicine cooperative treatment, KM diagnosis, prevention and regimen management. In the 'diagnosis part', the use of the symptom evaluation scale questionnaire was 41.8%, higher than the KM pattern diagnosis (34.4%). In the 'treatment part', herbal medicine accounted for 33.8%, higher than that of acupuncture (including electro-acupuncture) at 23.7%. 5. As for the expected development effects, opinions on evidence-based, safety, clinical use, and standardization were the most common. Conclusions: We figured out KM doctors' recognition of KM clinical practice guideline, clinical diagnosis, treatment on NVP to make the contents of the CPG reflecting the clinical situation.

In the coming future, anyone using the Internet will have more than one NFT. Unlike FT, NFT can specify the owner, and tracking management is easier than FT. Even in the 2022 survey, WPA2 is the most widely used wireless protocol worldwide to date. As it is a protocol that came out in 2006, it is a protocol with various vulnerabilities at this time. In order to use WPA2-EAP or WPA3 (2018), which were released to compensate for the vulnerabilities of WPA2, additional equipment upgrades are required for STA (station) and AP (access point, router), which are connected devices. The use of expensive router equipment solves the security part, but it is economically inefficient to be introduced in Small Office Home Office (SOHO). This paper uses NFT as a means of authentication and uses the existing WPA2 as it is without equipment upgrade, defend crack tools of WPA2 that have been widely used so far and compared to the existing WPA2, it was shown that it was not difficult to actually use them in SOHO.

Drought is a natural disaster that can have serious social impacts. Drought's impact ranges from water supply for humans to ecosystems, but the impact of drought on river water quality requires careful investigation. In general, drought occurs meteorologically and is classified as agricultural drought, hydrological drought, and environmental drought. In this study, the BOD environmental drought is defined using the bivariate copula joint probability distribution model between the meteorological drought index and the river BOD, and based on this, the environmental drought condition index (EDCI-BOD) was proposed. The results of examining the proposed index using past precipitation and BOD observation data showed that EDCI-BOD expressed environmental drought well in terms of river BOD water quality. In addition, by classifying the calculated EDCI-BOD into four levels, namely, 'attention', 'caution', 'alert', and 'seriousness', a practical monitoring stage for environmental drought of BOD was constructed. We further estimated the sensitivity of the stream BOD to meteorological drought, and through this, we could identify the stream section in which the stream BOD responded relatively more sensitively to the occurrence of meteorological drought. The results of this study are expected to provide information necessary for river BOD management in the event of meteorological droughts.

Purpose: The purpose of this study was to gain an in-depth understanding of the characteristics and competencies of practice experienced by public health center nurses(PHNs) during the early response phase of the coronavirus disease 2019(COVID-19) pandemic. Methods: PHNs were recruited from public health centers(PHC) in ten cities in Korea, using purposive sampling. They participated in semi-structured, in-depth interviews from December 21, 2020, to February 18, 2021. The interviews were transcribed verbatim and analyzed using qualitative content analysis. Results: Three themes and nine categories were drawn from the findings. The three themes that emerged from the data analysis were as follows: 'Handling expanding work scope and overwhelming workload beyond prepared competencies, willing to go anywhere.', 'Performing tasks of cooperation and communication required in the disaster management administrative system.', 'Demonstrated proficiency in clinical nursing practices, but recognized the need for further development of leadership and administrative capabilities.' Conclusions: The experiences of the subjects' have implications for the development of content for community nursing education that cultivates basic competencies to respond to real pandemic situations during undergraduate education. It is proposed that it would be necessary to establish a support system for developing specialized competencies in public health nursing.

Beyond the rapid normalization process of patents in software industry, complex legal evolution and rigorous economic arguments underlie the crucial environmental transformation of the industry. In this article, we trace the evolutionary history for the theory and practice of patents in software industry from both legal and economic perspectives. First, we study the legal disputes and cases in light with the underpinnings of patent policy transformation, and then delve into the economic backrounds of the pros and cons for software patents, with special focus on the generic economic peculiarities of software industry. The fact that historical and practical policy and law in Korea have been largely affected from those of USA, and relative deficiency in the law, economics and management literature are the main motivation of the study, and we hope this study to contribute to the decision making of policymakers as well as law and business practitioners.

There is enough precipitation and sunshine in Lae, Papua New Guinea. pH in soil of yam field averaged 6.4, that is suitable for yam growing. However, a great variation in pH was found from 3.7 to 6.4 in different locations around Lae. EC in the soil was 0.18 mS/cm that has shown short of soil nutrition but ORP was 393mV, allowing to be ideal for yam cultivation. Thoughtful management for soil fertility including supply of organic 1matters is needed for the sustainable organic yam production in Lae region, PNG.

This study was conducted to design and apply simulation-based problem-based learning classes, and then analyze the effects of class management using focus group interviews. In paramedicine, practical learning that can respond to various emergency situations based on major knowledge is important. In the case of problem-based learning classes, it is suitable for operating various topics covered by the Department of Paramedicine as it can improve capabilities such as problem-solving strategies, skills, and teamwork by providing practicality related to field situations for learning. This study developed a PBL module focusing on patients with dyspnea and applied it to medical emergencies and practice courses taken by 16 third graders of S University's Paramedicine department. Overall class satisfaction was high from 4.76 to 4.92. In particular, by resetting the learning strategy through PBL classes and experiencing cooperative learning, positive learning outcomes could be obtained and self-efficacy was experienced.

On Aug. 4, 2022, at 23:08:48 (UTC), the Korea Pathfinder Lunar Orbiter (KPLO), also known as Danuri, was launched using a SpaceX Falcon 9 launch vehicle. Currently, KPLO is successfully conducting its science mission around the Moon. The National Aeronautics and Space Administration (NASA)'s Deep Space Network (DSN) was utilized for the successful flight operation of KPLO. A great deal of joint effort was made between the Korea Aerospace Research Institute (KARI) and NASA DSN team since the beginning of KPLO ground system design for the success of the mission. The efficient utilization and management of NASA DSN in deep space exploration are critical not only for the spacecraft's telemetry and command but also for tracking the flight dynamics (FD) operation. In this work, the top-level DSN interface architecture, detailed workflows, DSN support levels, and practical lessons learned from the joint team's efforts are presented for KPLO's successful FD operation. Due to the significant joint team's efforts, KPLO is currently performing its mission smoothly in the lunar mission orbit. Through KPLO cooperative operation experience with DSN, a more reliable and efficient partnership is expected not only for Korea's own deep space exploration mission but also for the KARI-NASA DSN joint support on other deep space missions in the future.
