This study designed a data model linked to Wikidata and examined its applicability to increase the utilization of the digital archive records of the National Debt Redemption Movement, registered as World Memory Heritage, and implications were derived by analyzing the existing metadata, thesaurus, and semantic network graph. Through analysis of the original text of the National Debt Redemption Movement records, key data model classes for linking with Wikidata, such as record item, agent, time, place, and event, were derived. In addition, by identifying core properties for linking between classes and applying the designed data model to actual records, the possibility of acquiring abundant related information was confirmed through movement between classes centered on properties. Thus, this study's result showed that Wikidata's strengths could be utilized to increase data usage in local archives where the scale and management of data are relatively small. Therefore, it can be considered for application in a small-scale archive similar to the National Debt Redemption Movement digital archive.

A large number of expressed sequence tags (ESTs) in public databases have provided an opportunity for the systematic development of simple sequence repeat (SSR) markers. EST-SSRs derived from conserved coding sequences show considerable cross-species transferability in related species. In the present study, we assessed the utility of foxtail millet EST-SSRs in barnyard millet. A total of 312 EST-SSRs of foxtail millet were tested using 84 Echinochloa crus-galli germplasm accessions; a high rate of transferability (62%) and 46 primer sets (13%) were shown the polymorphism in barnyard millet. The 13% of functional EST-SSRs) was demonstrated between cereals and barnyard millet. SSR marker profile data were scored for the computation of pairwise distances as well as a Neighbor Joining (NJ) tree of all the genotypes. The averaged values of gene diversity (H_E) and polymorphism information content (PIC) were 0.213 and 0.179 within populations, respectively. The 84 barnyard millet germplasm accessions were divided into five different groups, which agreed well with their geographical origins. The exotic 12 accessions of India type barnyard millet (E. frumentacea) were all separated form Korean local collection genotype. The present results provide evidence of divergence between cultured and wild type barnyard, as a millet and grass. The polymorphic SSR markers indicated in this study were of great value in analysis of genetic diversity that can be further used for crop improvement through breeding.

Purpose: the study aims to examine the impact of ICT on the formation of digital hubs in regions of Kazakhstan, specifically the influence of ICT costs on the level of innovation activity of enterprises, the number of its actors as legal entities by size and region, small and medium enterprises, universities and research and development organisations. Research design, data and methodology: the research methodology is based on the collection of secondary data from the official statistical yearbooks of the Bureau of National Statistics of the Republic of Kazakhstan and the use of quantitative methods, in particular, correlation analysis and multiple regression. Five indicators related to the formation of digital hubs in the regions of the country were selected. Results: the study revealed that ICT spending has an impact on the formation of digital hubs in regions, in particular on the development of the number of legitimate enterprises, SMEs and R&D organisations as actors in digital hubs. A positive dynamic in the growth of the number of actors is visible. However, the hypotheses on the impact of ICT costs on the number of universities and the level of innovation activity were not supported. Conclusions: based on the results of the study, recommendations such as government proposals on strategy development, funding projects of innovation and digital hubs, and business proposals on engaging local entities in digital transformation for the formation of digital hubs in the country's regions have been developed.

Developing countries and small local governments face financial constraints, limiting the adoption of their own bus information systems. However, despite poor social infrastructure and low income levels, developing countries have a high smartphone penetration rate, and the distribution and usage of online content and social media are widespread. Smartphones, equipped with GPS sensors, cameras, and other location-based information collection capabilities, can replace expensive on-site terminals. This study aims to replace expensive on-site terminals with smartphones, develop a center system based on cloud servers, and establish an extensible Open BIS (Bus Information System) service and platform that can be applied anywhere. The goal is to formulate a business model in the process.

Purpose: The purpose of this study was to determine the effect of preoperative guidance and operating room environment experience using virtual reality on increasing satisfaction with information and reducing anxiety in preoperative patients undergoing general anesthesia and local anesthesia. Methods: A non-equivalent control group quasi-experimental design was employed. The participants were 80 surgical patients from 4 wards (40 experimental group and 40 control group) of the general hospital located in Gyeonggi-do. Data collection was conducted from June to November 2023 after completing the control group survey in January 2023. Data were analyzed using Chi-square, t-test, and Mann-Whitney U test using SPSS 23.0 program. Results: Satisfaction with preoperative information was higher in the experimental group than that of the control group. Additionally, anxiety related to surgery in the experimental group was significantly lower than that of the control group. The preoperative state anxiety score in the experimental group was not significantly lower than that of the control group. Conclusions: These results suggest that providing patient education and information using virtual reality technology can not only alleviate patients' anxiety related to surgery, but also have the potential to be used as an effective intervention to improve positive patient experiences.

Lipedema is a progressive connective tissue disease with enlargement of adipose tissue, fibrosis, fluid collection, and dermal thickening. Herein, we present a case of lipedema associated with skin hypoperfusion and ulceration in which soft tissue debulking with liposuction improved patients' symptoms. A 39-year-old female presented with asymmetric progressive initially unilateral lower limb swelling with severe pain with subsequent skin ulceration. Conservative management failed to improve her condition. After excluding other causes and detailed radiologic investigation, lipedema was diagnosed with an associated impaired skin perfusion. Trial of local wound care and compression therapy failed to improve the condition. Subsequent soft tissue debulking with circumferential liposuction and ulcer debridement and immediate compression showed dramatic improvement of the symptoms and skin perfusion. The unique nature of this case sheds light on lipedema as a loose connective tissue disease. Inflammation and microangiopathies explain the associated pain with hypoperfusion and ulceration being quite atypical and in part might be related to the large buildups of matrix proteins and sodium contents leading to fragility in microvessels with frequent petechiae and hematoma and subsequent tissue ischemia. Conservative measures like compression therapy plays a significant role in disease course. Surgical debulking with liposuction was shown to be efficacious in reducing the soft tissue load with improvement in limb pain, edema, circumference, and skin perfusion that was seen in our patient. Lipedema is a frequently misdiagnosed condition with disabling features. Skin involvement in lipedema with potential hypoperfusion was shown and it requires further investigation.

In this paper, the maximum scour depths at piers located in the Bo Cheong Stream, which is a tributary in the Geum River System, were calculated and compared using 24 local pier scour equations. The equations were classified as six groups by non-dimensional types of equations. The geometric data in the stream bed and pier data at San Seong, Yi Pyung and San Gye, which are IHP data collection stations, were utilized for applying the scour equations. The geometric data in the stream bed were obtained by analyzing the bed material sampled in three stations which are in the left side, middle and right side for stream direction. The maximum flow velocities at maximum flow depths which were measured from 1982 to 1991, were used as the hydraulic flow data. The pier data for predicting pier scour depths were measured in the fields. The maximum pier scour depths calculated using the equations were compared with the held scour depths measured in the streams or rivers in the world. Arunachalam, Shen-Karaki III, Jain-Fischer equations are selected as the proper local scour equations for predicting the maximum local scour depths at piers in the Bo Cheong Stream. Inglis-Lacey and Shen-Karaki II equations are applicable in case of rapid flows conditions in which Froude number is over 0.3. Froehlich, Laursen I, Laursen II, Neill, Melville equations are applicable in the slow flow conditions in which Froude number is less than 0.3. Blench equation or Inglis-Poona equation varies rapidly by changing Froude numbers. Therefore the equations should not be used without careful considerations in selecting the applicable ranges. The maximum local scour depths calculated using Sarma-Krishnamurthy, Ahmad, Coleman, Varzeliotis, Larras, Bata, Chitale, Venkatadri, Basik-Basamily-Ergun, U.S.G.S., Shen I equations are usually less than the scour depths measured in the fields.

There are two main perspectives in Korea on Korean cultural heritage located overseas: one views it as items that need to be repatriated since they were scattered abroad under unfortunate historical circumstances. The other considers them as a means to more widely promote Korea's culture and long history. A shift in perspective has gradually been taking place in the decades since Korea's liberation from Japanese colonial rule in 1945. This can be noted through three major types of exhibitions. The first type is exhibitions of repatriated cultural heritage that showcase items that were illegally removed from the country but later returned or otherwise acquired through purchase or donation. The Special Exhibition of Returned Cultural Heritage, which was held in 1966 on the occasion of the normalization of diplomatic relations between the Republic of Korea and Japan, emphasized the legitimacy of reclaiming cultural properties that were illegally removed from Korea during the period of Japanese colonial rule. Around the 1990s, special exhibitions of private donations were held, which also highlighted the legitimacy of repatriation. The special exhibition of the Oegyujanggak Uigwe (Royal Protocols of the Joseon Dynasty from the Outer Royal Library) held in 2011 was seen as an opportunity to raise public interest in repatriation, heal the wounds of history, and restore the nation's cultural pride. The second type of exhibition involves borrowing and displaying overseas Korean cultural heritage in accordance with a theme as a means to reenergize and provide a comprehensive view of Korean culture. The exhibitions National Treasures from the Goryeo Dynasty in 1995 and National Treasures from the Early Joseon Dynasty in 1997 (both held at the Hoam Museum of Art) and the Masterpieces of Goryeo Buddhist Painting held at the National Museum of Korea in 2010 underscored the importance of overseas Korean cultural heritage for exploring Korean cultural history. The third type is special exhibitions on the history of the collection of Korean cultural heritage. With Korea's economic growth in the 1980s and the increase in exhibitions and the number of galleries featuring Korean cultural heritage in overseas museums in the 1990s, interest in the history of acquisition also grew. Exhibitions like The Korean Collection of the Peabody Essex Museum in 1994 and Korean Art from the United States in 2012 introduced overseas galleries focused on Korean art and the diverse history of collecting Korean cultural properties. They also examined the perception of Korean art in the United States. These efforts heightened public interest in establishing and supporting Korean galleries abroad. The initiation of more systematic surveys and research on Korean cultural heritage located abroad and the contribution of overseas Korean cultural heritage to the enhancement of the local understanding and promotion of Korean culture have resulted in changes to the perception of overseas Korean cultural heritage in Korea.

A new, improved maize varieties are greatly needed to meet the national demand for the maize, and a new germplasm should be investigated to supply necessary breeding materials for the required maize breeding. The Korean local maize lines, which has never been wholly studied for the purpose of breeding should be enough to supply such breeding materials at least in Korea. The objectives of this study were to maintain useful Korean local lines, to investigate good plant characters and to analyze the Korean local maize lines in the respect of genetic make-up. A total of 820 lines and 200 lines were used for the present study. Lines to maintain were planted at experimental farm of the Crop Experiment Station, Office of Rural Development, Suwon and the lines to study genetic make-up were planted in Dae-jon. The summarized results are as follows : 1. A total of 1200 lines from 820 collections were sibbed for future use. 2. Two hundred collection were sibbed, selfed and testcrossed for genetic study in 1980. 3. Ten lines were surely confirmed as resistant lines to virus disease epidemic in most introduced maize varieties. 4. A dozen Lines were having three to four ears per plant. 5. Five lines were showing three to four tillers per plant. 6. One of the most significant and important finding through the study was to obtain the lines with three to four tillers bearing all together eight to nine ears. The lines of multi-ears and multi-tillers must have great breeding potential for the future use. 7. A great variation was observed in the tasselling days, 100 kernel weight and protein content. 8. From the genetic study of local maize lines for plant height and 100 kernel weight, the following findings were obtained. a. On the average six percent of inbreeding depression expressed in percent decrease over sibbed counterpart were found for the plant height. b. Fourty percent of heterosis expressed in percent increase over sibbed counterpart were observed in the plant height. c. The homogeneity or degree of homozygosity calculated from heterosis minus inbreeding depression was on the average 34 percent for plant height. d. The average inbreeding depression expressed in percent decrease over sibbed counterpart was 15 percent for 100 kernel weight. e. The average heterosis expressed in percent increase over sibbed counterpart was 43 percent for 100 kernel weight. f. The degree of homozygosity calculated from the heterosis minus inbreeding depression was 28 percent for 100 kernel weight.
