Purpose: The purpose of this article is to clearly describe research trends on health life expectancy using oral health indicators that have been published from 2010 to 2020 then suggest the direction of future research. Methods: Online academic databases in English (PubMed, Web of Science and Embase) were used to find those articles by applying a variety of keywords, including terms (adjusted life year, adjusted life expectancy, dental and oral). We identified relevant articles based on the following classification method of Mathers: (1) health gaps, (2) health expectancies. Results: Among 1,728 articles from the online databases, the final 13 studies satisfied the inclusion criteria and were selected for analysis. Health life expectancy studies indicate that research growth was recently achieved overseas. Among the literature collected in this study, 10 studies using health gap indicators yielded seven Disability-Adjusted Life Year (DALY), and three calculated Quality-Adjusted Life Year (QALY), which differed in the nature of the survey data used in the study measuring DALY and QALY. There are only three health expectancies and the number of papers were smaller than the health gap study. Conclusion: Establishing a foundation to calculate health life expectancy indicators through the development and improvement of oral health level are needed. More studies in the area of health life expectancy estimation research is based on actual prevalence and oral health-related quality of life are also needed.

The Samsung gold-silver deposit consists of quartz veins that fill along the fault zone within Cretaceous shale and sandstone. Mineralization is occurred within fault-breccia zones and can be divided into two stages. Stage I is main ore mineralization and stage II is barren. Stage I is associated with wall-rock alteration minerals(sericite, pyrite, chlorite, quartz), rutile, base-metal sulfides(pyrrhotite, pyrite, sphalerite, chalcopyrite, galena), and electrum. Stage II occur quartz, calcite and pyrite. Fluid inclusion data indicate that homogenization temperatures and salinities of stage I range from 145 to $309^{\circ}C$ and from 0.4 to 12.4 wt.% NaCl, respectively. It suggests that hydrothermal fluids were cooled and diluted with the mixing of meteoric water. The main deposition of base-metal sulfides and electrum occurred as a result of cooling and dilution at temperature between $200^{\circ}C$ and $300^{\circ}C$. Sulfur(9.3~10.8‰) isotope composition indicates that ore sulfur was mainly derived from a magmatic source as well as the host rocks. The calculated oxygen[-2.3~0.9‰(quartz: 0.3‰, 0.9‰, calcite: -2.3‰)] and hydrogen[-86~-76‰(quartz: -86‰, -82‰, calcite: -76‰)] isotope compositions indicate that hydrothermal fluids may be meteoric origin with some degree of mixing of another meteoric water for paragenetic time.

The government has recognized the importance of smart city indicators and prepared the legal grounds for the certification of smart cities in the recently revised "Act on Smart City Development and Industrial Promotion." This study derived smart city indicators adequate for the domestic conditions and compatible with the overseas trends by examining and complementing the indicators through an AHP analysis based on consultations and interviews (surveys) with experts and local government officials, who are actually carrying out related projects. In addition, the adequacy and reliability of the indicators were confirmed by verifying and certifying the Korean local governments' smart city plans through demand surveys on a trial basis. This study is meaningful in that it systematically studies the smart city indicators that have gained in importance and reviews their application. The findings of this study can be used as a basis for implementing a smart cities certification system in the future. Recently, the Special Committee on Smart Cities was established under the Committee for the Fourth Industrial Revolution. This committee is composed of civilian members and is working with the Ministry of Land, Infrastructure, and Transport, the Ministry of Science and ICT, etc., to promote the creation of smart cities. It is expected that smart city indicators that include the levels of both domestic and overseas smart cities will boost the active spread of such cities in Korea.

The global popularity of K-content(Korean Wave) has led to a continuous increase in copyright infringement cases involving domestic works, not only within the country but also overseas. In response to this trend, there is active research on technologies for detecting illegal distribution sites of domestic copyrighted materials, with recent studies utilizing the characteristics of domestic illegal distribution sites that often include a significant number of advertising banners. However, the application of detection techniques similar to those used domestically is limited for overseas illegal distribution sites. These sites may not include advertising banners or may have significantly fewer ads compared to domestic sites, making the application of detection technologies used domestically challenging. In this study, we propose a detection technique based on the similarity comparison of links and text trees, leveraging the characteristic of including illegal sharing posts and images of copyrighted materials in a similar hierarchical structure. Additionally, to accurately compare the similarity of large-scale trees composed of a massive number of links, we utilize Graph Neural Network (GNN). The experiments conducted in this study demonstrated a high accuracy rate of over 95% in classifying regular sites and sites involved in the illegal distribution of copyrighted materials. Applying this algorithm to automate the detection of illegal distribution sites is expected to enable swift responses to copyright infringements.

Objectives To assess the effectiveness of chuna manual therapy for patients with total knee arthroplasty. Methods We searched 9 electronic databases(KISS, NDSL, RISS, OASIS, KMBASE, Cochrane Library, PubMed, CNKI, Wangfang data) using the keywords 'total knee arthroplasty OR total knee replacement' and 'tuina OR chuna' to identify RCTs that investigated the effectiveness of Chuna manual therapy after total knee arthroplasty. Results 23 RCTs were selected based on inclusion criteria. The systematic review showed positive effect of using chuna manual therapy after total knee arthroplasty. Conclusions 23 studies reported that chuna manual therapy had significant effects on total knee arthroplasty. However, many studies were exposed to probable high risk of bias. Also, all of the studies were published in one overseas country. Therefore, further research is required using well-designed RCTs to support the effectiveness of chuna manual therapy.

To increase the utilization of the KOrea Multi-Purpose SATellite(KOMPSAT) series imagery being developed pursuant to the national space development program, high quality images with enhanced locational accuracy should be created through standardized post-processing processes. In the present study, using the Value-Added Processing System(VAPS) constructed for the post-processing of KOMPSAT imagery, location correction experiments were conducted using KOMPSAT-2 and -3 imagery from domestic and overseas regions. First, 50 pieces from each of KOMPSAT-2 imagery were selected from South Korean and North Korean regions, and modeling was conducted using GCP Chips. According to the results, the Root Mean Square Errors(RMSE) for South Korea and North Korea were 1.59 pixels and 2.04 pixels, respectively, and the locational accuracy of ortho mosaic imagery using check points were 1.33m(RMSE) and 1.90m(RMSE), respectively. Meanwhile, in the case of overseas regions for which GCP could not be easily obtained, the improvement of locational accuracy could be identified through image corrections using Open Street Map(OSM). The VAPS and reference materials used in the present study are expected to be very useful in constructing a precise image DB for entire global regions.

The proliferation of online reviews on dining experiences has significantly affected consumers' choices of restaurants, especially overseas. Food quality, service, ambiance, and price have been identified as specific attributes for the choice of a restaurant in prior studies. In addition to these four representative attributes, cultural factors, which may also significantly impact the choice of a restaurant for tourists, in particular, have not received much attention in previous studies. This study employs the text mining technique to analyze over 10,000 online reviews of 76 Korean restaurants posted by Chinese tourists on dianping.com to explore the influence of cultural factors on the consumer's choice of restaurants in the overseas travel context. The findings reveal that "Hallyu (Korean Wave)" influences Chinese tourists' dining experiences in Korea and their satisfaction. Moreover, Korean food-related words, such as cold noodle, bibimbap, rice cake, pig trotters, and kimchi stew, appeared across all the review topics. Our findings contribute to the existing tourism and hospitality literature by identifying the critical role of cultural factors on consumers', especially tourists', satisfaction with the choice of a restaurant using text mining. The findings also provide practical guidance to restaurant owners in Korea to attract more Chinese tourists.

The treatise is a follow-up thesis of "The Archival Management : destination of its education" published by The Research Institute for Korean Archives and Records in June 17, 2000, and it was written to secure its original temper of the "Archival Management" which has established at first as the domestic collegiate educational course. Presently, we are mixed up for interpretation of terminology by facing unfamiliar words: such as, Archives, Documents, Manuscripts, Records / Archival Management, Archival Preservation / Archivist, Archival Conservator, Manuscripts Curator and Record Manager. Also, tile treatise has confirmed scholars' various opinion about its education and curriculum not only domestic but overseas scholars, and examined realities and course of studies of 4 overseas countries, and also have purpose to pursue domestic universities' actual condition of curriculum and its reform measure. And since dispositon of Archivist and the professional organization of the Archivist was based on the Laws, therefore, establishment of an educational institution for Archival Management from now on will be expanded more and need to be accelerated. Accordingly, the universities that already established or to be established from now on, shall be needed educational quality and its contents to be ascended. Its concrete plan is as follows : (1) Now, disarranged archive and record words, and to make publish 'Glossary of Archives & Records' as soon as possible. (2) Remind the substance of the Record and Archival Management and its sphere again and need to be considered alteration of the studies' name. (3) There needs to establish the role and establishment of conception of Archivists. (4) Refer to the theory and practical educational method of overseas professional Archivist Scholars, but to be needed to develop the curriculum which is accorded with am tradition and way of thinking. (5) Confer for development of teaching materials and educational method jointly through 'Academic Society', and there needs reorganize the subject which is fit for each university's characteristics. (6) Recently, "Cultural Resources Studies" for research specialization which has established in Graduate School of Tokyo University was very useful to us. We also need to be considered such establishment of process.

In developing offshore wind farms, many environmental issues arise because of the concentration on supply demand and economic logic. Accordingly, community conflict is induced. Especially, recent studies regarding the capacity and location of offshore wind development have been conducted considering wind states and ocean conditions, etc. of coastal seas in Republic of Korea. Nevertheless, studies on the impact of marine environments and ecosystems are very limited so far. Environmental monitoring that follows development projects has been actively done in the offshore wind farms in many developed European countries. In contrast, there is no domestic monitoring data regarding environmental impacts caused by installing and operating offshore wind power. Therefore, the environmental impacts under construction and operation phases as well as the guidelines in the stage of environmental impact assessment suited for domestic coastal seas are well presented in this study by analyzing monitoring cases and references of overseas offshore wind farm. For this reason, this research is ultimately aimed at minimizing the environmental impact in offshore wind farm development and thus simplify administrative procedures in Korea.

For the estimation of greenhouse gas dynamics in forests, it is useful to use a model which simulates both carbon (C) and nitrogen (N) cycle simultaneously. A forest C model, called FBDC, was developed and validated in Korea. However, studies on development of forest N model are insufficient. This study aimed to suggest a development process of a forest C and N model. We analyzed the general features, structures, ecological processes, input data, output data, and methods of integrating C and N cycles of the VISIT, Biome-BGC, Forest-DNDC, and O-CN. The structure and features of the FBDC were also analyzed. The VISIT was developed by integrating forest C model with a N cycle module, and the new model also could be designed by combining the FBDC with a N cycle module. The VISIT and Forest-DNDC could estimate soil $N_2O$ emissions, and the integrated model should include the processes shared by these models. Especially, the overseas models linked C and N cycles based on N absorption, C absorption, and decomposition of dead organic matter. Therefore, the integration of the FBDC with N cycle module should apply this linkage of structures between C and N cycles. Climate, soil texture, and species distribution data, which are essential for the model development, were available in Korea. However, parameter data associated with N cycle and validation data for soil $N_2O$ emissions need to be obtained by field studies.
