This paper examines the characteristics of the May 18th (5 18) Gwangju Democratization Movement archives to suggest a collection development strategy for the May 18th archives collection network. Individual public and civilian archives collecting the May 18th archives separately should form a cooperative collection network based on documentation strategy. Most of all, May 18th archives are human rights records and should be understood and collected as human rights records. International principles support the collection of the May 18th archives as human rights archives by prohibiting destruction of relevant temporary records and encouraging the victims' right to access to their records. As the May 18th archives were mostly produced by many multiple agencies, this multi-provenance and diversity of the records necessitate the building of an archives portal for the records registries and online search. To document the undocumented past and the victims, the collection network should focus on oral history project as a major part of its collection development strategy. Finally, the May 18th archives collection network should build a cooperative relations with the unwilling public agencies which have the archives holdings. Therefore, the collection development strategy should include advocacy and awareness activities for promoting cooperation from these public agencies and public archives, and the people in general.

This study examined the usability of express buses for wheelchair users to identify the effectiveness, efficiency and satisfaction of wheelchair boarding systems. The usability of 11 manual wheelchair users and nine powered wheelchair users was evaluated using the following three scenarios: boarding the wheelchair accessible bus, moving inside, and alighting the bus. The results showed that 20 wheelchair users completed three scenarios, which was distributed between 0.33 and 1.36 in the difficulty rating scale of the efficiency. The task effort of the efficiency was measured from 8.36 to 11.78. The acceptability of the satisfaction was distributed between 1.00 and 2.00, and the system usability scale was measured in an acceptable boundary of the C grade at 70.7 points with manual wheelchair users and a B grade at 73.1 points with powered wheelchair users. This study has academic significance because it provides basic evidence for accessibility, securing the right to movement and research methods of public transportation for people with disabilities. To improve the quality level of usability in the future, more study with a larger number of research participants and various wheelchair types should be studied.

This study was conducted to ascertain a better understanding of researchers' perception of open peer review (OPR), which is being attempted to improve the problems of traditional peer review methods in recent journal publications. A survey was conducted on the Korean authors of a mega open access (OA) journals and the results were analyzed. The subjects of the survey were selected as Korean corresponding authors published on PLOS, an international OA journal and mega journal. The survey was conducted as an online questionnaire and a total of 238 responses were collected; the analysis was based on 202 valid responses. Data were analyzed by performing frequency analysis and average comparison between groups for the collected questionnaire results. As a result of analyzing whether there is a difference in perception of OPR depending on the age, research experience, and OPR experience of the researcher, researchers under the age of 44, researchers with research experience of 9 years or less, and researchers with OPR participation experience had differences in some OPR perceptions. Results show that researchers under the age of 44 want to change the current peer review approach, but they are not yet actively accepting OPR. As a result of analyzing the reasons why the researcher disagrees with OPR, they raised questions about lack of objectivity, increased burden of reviewers, emotions and relationships, and responded that the right to be forgotten was also necessary.

Cloud of Things (CoT) can provide IoT applications with unlimited storage functions and processing power supported by cloud services. However, in a centralized cloud of things, it can create a single point of failure that can lead to bottleneck problems, outages of the CoT network. In this paper, to solve the problem of centralized cloud of things and interoperate between different service domains, we propose an IoT service interoperability system using distributed fog computing and blockchain technology. Distributed fog is used to provide real-time data processing and services in fog systems located at a geographically close distance to IoT devices, and to enable service interoperability between each fog using smart contracts and distributed ledgers of the blockchain. The proposed system provides services within a region close to the distributed fog entrusted with the service from the cloud, and it is possible to access the services of other fogs without going through the cloud even between fogs. In addition, by sharing a service right token issuance information between the cloud and fog nodes using a blockchain network, the integrity of the token can be guaranteed and reliable service interoperability between fog nodes can be performed.

Due to the Covid-19 Pandemic, the world is facing the most serious crisis since the Great Depression, and is facing a new paradigm of the Untact era. Korea has also announced various policies and legal systems, including the 'Korean version of the New Deal', but it is conflicting between the use of information and the protection of information. In this paper, we derive thresholds by analyzing policies, statutes and technologies in the public cloud. Based on this, we propose to introduce the "Building a Nationwide Public Virtual Machine" as a key task to secure the next-generation national growth engine so that all citizens can use digital services in a secure and reliable environment with equal access to information. Through this, all citizens can use various digital new technology services only with low-priced and low-specification terminals, and by establishing a dedicated center for information protection, we want to respond to rapidly increasing security threats. It also points out that the domestic cloud-related legal system only emphasizes the use of information while overlooking the importance of security, and suggests the right direction for the legal system to move forward.

TTH(tension-type headache) is the most common primary headache among adults. Long-term headaches cause chronic headaches and have a better impact on daily life. The purpose of this study is to compare the contributions to TTH through AVE(audio-visual entertainment) and STM(soft tissue mobilization) suitable for management of pathogenic and psychogenic factors of TTH. The participants of this study were from 30 people who complained of intermittent or persistent headaches for more than 6 months, and 10 participants each in the AVE group, STM group, and AVE plus STM group. In the assigned group, a total of 12 sessions were performed three times a week for 4 weeks after the baseline, followed by post-test. Outcome measures measured PPTs(pressure pain thresholds), psychophysiological parameters, and EEG(electroencephalogram). The measured results were analyzed for interaction between time and group through a two way rmANOVA(repeated measurement variance analysis). As a result of the PPTs, interaction was found in the results of the right trapezius (p<.05), and the more improvement was observed in the AVE group. Therefore, through AVE based on psychological factors rather than direct access to the muscles of pathogenic factors, a positive impact on the PPTs was shown, but the average value of the psychophysiological parameters and brain waves that were not statistically significant. The amount of change was observed. Through this, it is suggested that audio-visual stimulation could be considered in the management of TTH.

The goal of this study is to explore and draw implicaitons from international and domestic media and information literacy (MIL) policies and educational systems. To this end, international policy documents issued by UNESCO, IFLA, OECD, and the EU as well as domestic South Korean laws and policies related to MIL and the fuctions of public libraries and related institutions were analyzed. The findings show that international organizations recognize public libraries as institutions that are responsible for providing information access and supporting knowledge sharing for citizens within and outside of formal education systems. Additionally, public libraries are seen as institutions responsible for supporting lifelong learning and civic education, as well as improving media, information, and digital literacy skills of their communities. In South Korea, the Library Act gives public libraries and librarians responsibility for improving citizens' MIL to support the public's right to know and to narrow the information gap. However, the functions of public libraries and librarians in South Korea have been limited or excluded in the domestic MIL policies. This study concludes that public libraries and librarians are responsible for reducing the information gap among citizens and should actively participate in policy development to improve citizens' MIL skills.

Objectives: Surgical intervention for removal of an impacted third molar can lead to significant pain and swelling. Corticosteroids show promise for mitigating postoperative sequelae across various surgical contexts. The use of corticosteroids following minor oral surgery, though controversial, has already been proven effective. However, little research has explored peroral prescription of corticosteroids despite its convenience for outpatients and for non-surgeons like implantologists and periodontists and others who don't have access to needle injections. The aim of this study was to address a void in the literature by comparing the effects of two styles of preoral administration of prednisolone after surgical removal of the mandibular third molar and to determine which style minimizes postoperative sequelae. Materials and Methods: A randomized, split-mouth clinical study was conducted to investigate the efficacy of two different styles of preoral prednisolone in mitigating postoperative sequelae following surgical extraction of impacted mandibular third molars. Fifteen participants were enrolled in the study. Random selection was used to determine the prescription style for the right and left mandibular arch. Group A included those who received a single dose of prednisolone 25 mg, while group B received prednisolone 5 mg postoperatively for a period of three days (5 mg three times/day on the first postoperative day, 5 mg twice/day on the second postoperative day; 5 mg once/day on the third postoperative day). Results: There was a significant difference in the distance between the corner of the mouth and tragus, which decreased with the time interval with respect to group B when compared to group A. Conclusion: The present study showed that a three-day tapered dose of prednisolone postoperatively was more effective in reducing post-extraction sequelae than a single-dose regimen.

A frequent flyer program is a loyalty program offered by many airlines. Typically, airline customers enrolled in the program accumulate frequent flyer miles corresponding to the distance flown on that airline or its partners. There are other ways to accumulate miles. In recent years, more miles were awarded for using co-branded credit and debit cards than for air travel. Acquired miles can be redeemed for free air travel; for other goods or services, such as travel class upgrades, airport lounge access or priority bookings. The first modern frequent flyer program was created Texas International Airlines in 1979. This program was also adopted in Korean Air in 1984. Since then, the mileage programs have grown enormously. As of June 2009, the total member of two national airlines in Korea had been over thirty million. However, accumulated miles could be burden of airlines, because the korean corporations should record the annual financial report the accumulate mileage on a liability account by 'the international financial report standards(IFRS)' next year. The korean airlines need to minimize the accumulated miles, so that for instance Korean Airlines SKYPASS-miles expire 5 years after being earned. It means that miles earned on or after July 2008 will expire after five years if unredeemed. Thus, this paper attempt to analyze the unfairness of the mileage rules of korean airlines by examining a specific portion of the conditions relating to consumer protection, because many mileage users has difficulties using mileage programs and complained the amendment of the mileage rules. In conclusion, the contemporary mileage rules in Korea are rather unsatisfactory, because airlines is not only recognizing a mileage into a kind of benefit but also denying inheritance of mileage and the legal nature of mileage as a property right. It is necessary to amend relevant mileage rules in view of consumer protection, because air mileage is not simple benefit but a right of mileage user.

The arteriovenous fistula (AVF), which maintains satisfactory blood flow, is necessary to the patients of end-stage renal disease for the long term hemodialysis. We performed the snuffbox fistula as the first operation for hemodialysis vascular access. This study was performed to investigate the patency rates, complications, risk factors for occlusion of the AVF, and the types of reoperations. Material and Method: We performed 146 snuffbox fistulas from Jun. 1994 to Dec. 2001 The records of the patients except six patients who were lost from follow up were analyzed retrospectively, Mean age and male:female ratio were 52$\pm$15 years (range, 17∼79 years) and 80 : 60 respectively. Diabetes mellitus and hypertension were combined in 47 patients and 101 respectively. Preoperative levels of creatinine and potassium were 9.09$\pm$3.68 mg/dL (range, 2.55∼20.09 mg/dL) and 4.7$\pm$0.9 mmol/L (range, 2.3∼8.1 mmol/L). One hundred thirteen cases of the snuffbox fistulas were done at left side hand and the others at right hand. Result: Mean follow up period of the patients was 41.8$\pm$31.0 months (range, 0.2∼108,8 months). During the follow up period, 35 occlusions of AVF occurred and these AVFs were patent for 9.8$\pm$10.1 months (range, 0.1∼40.4 months). The patency rates of f month, and 1, 2, 3, 5 years were known as 92.8, 80.2, 73.8, 71.3, 69.6% respectively. Right sided snuffbox fistulas (p-value=0.045) and old age (p-value=0.048) were revealed as significant risk factors for occlusion of AVF. The postoperative complications consisted of occlusions of AVF caused by intimal hyperplasia of vein in 24, thrombosis in nine, stenosis of anastomosis site in three, and venous hypertensions in two. After the first operation 37 patients underwent 86 reoperations. Conclusion: The snuffbox fistulas showed acceptable patency rates and low complication rates. The snuffbox fistulas as the first operation for AVF formation can be a good option for the patients with end-stage renal disease.
