  • This study explored journal publishing and authorship by South Korean early career researchers (ECRs) in the field of library and information science (LIS). This research analyzed relevant journal publication data and conducted interviews to obtain information on the experiences and opinions of ECRs. Results indicated that South Korean ECRs in LIS were highly productive. This was evidenced by their annual publishing rate of 2.04 articles per person. In addition, Social Science Citation Index (SSCI) publications were produced at an annual average of 0.26 articles per person, while the quartile ratings for SSCI journal publications were also relatively high. However, unlike the trends seen in other academic fields, their collaborative research efforts were not considered very high because such efforts did not correspond to half their total publications. ECRs often participate as lead or corresponding authors despite being new researchers. ECRs are publishing first in the journals approved by their universities. These researchers cannot receive proper credit if the journal was not approved in this manner. ECRs are particularly disadvantaged when publishing in international journals corresponding to specific areas that are not on the SSCI list. By examining the journal publishing and authorship efforts of ECRs, this study discovered a variety of difficulties that should be addressed. For example, South Korean universities do not currently have cooperative research guidelines to solve authorship problems. The results from this study can serve as a basis to establish academic publishing and authorship policies while promoting scholarly communication in LIS and other scientific fields.

  • We analyze the global market for flexible electronic circuits, technical considerations, and analyze the market for application areas and regions. In the market analysis of the application field, the display field has the greatest influence in terms of market size and annual growth rate, and the OLE D lighting market size is expected to grow by nearly 50% in 2026. The multilayer flexible electronics, which dependently requires the semiconductor technology, has a larger market size than other structures and its growth rate is relatively large, leading the market and will be further analyzed in depth. The market size of multilayer flexible electronics applied to display field is expected to show an annual growth rate of 21.1% from $2.7 billion in 2017 to $9.8 billion in 2026, and the OLED market is expected to grow by 75.2% during the same periods. Recently, as electronic products have been miniaturized and advanced, and robust installation in a small space is required, companies that preoccupy multilayer structure or rigid flexible electronic circuit technology have an advantage in competitiveness, so many companies are trying to obtain this technology. These efforts are systematically supported by many countries because they can achieve mutual growth by strengthening the competitiveness of the application field and the same industry. In the case of Korea, a support system is established, but it is required to expand and activate it, and to localize manufacturing equipment and materials.

  • The aim of this study was to estimate genetic parameters and annual trends on the racing performance of Thoroughbred horses by a statistical analysis of the resulting records. We used the racing results of 245,979 observations for 13,458 horses recorded in 19 years of race held at Seoul and Busan racing tracks, provided by Korea Racing Authority. After a careful adjustment of some variables such as racing times, jockey and trainer numbers and the average prize a horse won, we selected significant factors that explain the result of racing records of a horse by stepwise AIC and BIC methods. The estimated heritability and repeatability were 0.322 and 0.332, respectively. The average of annual phenotypic and genetic improvement was -0.166 seconds and -0.161 seconds, respectively. Based on the statistical approach, we established reasonable animal model of well-set variables, which is important in the study on estimating performance of racing horses.

  • Population and urban development along the coast is growing in South Korea, and particularly sea level rise is likely to increase the vulnerability of coastal areas. This study aims to investigate the sea level rise through Mann-Kendall(MK) test, ordinary linear regression(OR) and quantile regression analysis(QRA) with sea level data at the 20 tide stations along the coast of Korean Peninsula. First, statistically significant long-term trends were analysed using a non-parametric MK test and the test indicated statistically significant trends for 18 and 10 stations at the 5% significance level in the annual mean value of sea level and the annual maximum value of sea level, respectively. The QRA method showed better performance in terms of characterizing the degree of trend. QRA showed that an average annual rise in mean sea level is about 1-6 mm/year, and an average rise in maximum sea level is about 1-20 mm. It was found that upward convergent and upward divergent were a representative change given the nine-category distributional changes. We expect that in future work we will address nonstationarities with respect to sea level that were identified above, and develop a nonstationary frequency analysis with climate change scenarios.

  • Objectives: This study identifies the trends in possible and probable occupational disease among chromium workers and reviews the literature on domestic and foreign chromium workers to review the industries, biological exposure levels, and major results. Methods: The results of the Ministry of Employment and Labor's special health-screening program for hazard agents among workers from 2009 to 2019 were used. Also, the industries, biological exposure levels, and major results on chromium workers were reviewed using PubMed and RISS. Results: The average annual proportion of both possible and probable occupational disease for chromium workers has recently increased. The average annual proportion of possible and probable occupational disease that can occur was high for both men and women in their 60s or older by age and 10 to 14 years by work duration. By industry, possible occupational disease showed high in manufacturing. In the literature review, many electroplating-related chromium-workers reported high levels of exposure to blood and urine chromium, as did dental technicians; tannery, tile factory or glass mill workers; cement workers; and sodium bichromate workers. Furthermore, a number of main findings in recent studies have reported that chromium exposure is related to genetic toxicity among workers. Conclusions: In this study, the average annual rate of both possible and probable occupational disease in domestic chromium workers is increasing, and a body of literature shows that chromium exposure is related to genetic toxicity and associated indicators among workers, which requires more systematic study.

  • The purpose of this study is to analyze research trends in post-occupancy evaluation and to identify its Improvement strategy. Also this study suggests historical development of domestic researches on POE and current discussions to POE in architectural fields. The results were as follows. In Korea, 55 papers on POE method were published from 1990 to 2010. In the 1990s, with the introduction of POE method, researches focused on its potential or limitations and presented the barriers to the adoption of POE. In the 2000s, POE researches mainly were apartments evaluation researches by residents' satisfaction. Designers and construct companies feel it is necessary to perform POE, indeed it is difficult to find POE researchers and utilize POE data. Nevertheless, some of them have performed POE of their building and got feedback from residents. In conclusion, it is necessary to minimize the barriers to adoption of POE and to develop its potential. Therefore, it should be performed POE by stakeholders and POE data would be provided a variety of types. Furthermore, POE certification system should be designed at the government level. Basically, POE courses must be included in the architectural curriculum.

  • Privacy laws are widely enforced throughout the general public and private sector, and the Ministry of Government Administration and Home Affairs is stepping up its annual level of protection and management levels annually. However, in actual field, it has limits to follow the laws that are amended to comply with the privacy laws of the public sector. Therefore, this study should examine the trends of privacy protection and examine items that require adherence to privacy practices in public institutions. In addition, it is hoped to draw implications for the problems arising from the task itself, as well as providing implications for the issues that are closely related to the public in the privacy of the privacy policies.

  • The objective of this study was to investigate the recent incidence and mortality trends for breast cancer in Mexican females. Data between 2000 and 2010 from the Department of Epidemiology of the Ministry of Health, and International Agency for Research on Cancer (IARC) were analyzed. Age-standardized rates (ASRs) and annual percent changes (APCs) were calculated. The absolute incidence and mortality rates of breast cancer increased: 3,726 and 4,615 in 2000 to 8,545 and 4,966 in 2010, respectively. Incidence increased over time in all age groups tested, the 60-64 age group had the highest ASR (57.4 per 100,000 women in 2010), while the 20-44 age group had the lowest ASR (12.3 in 2010). The results show that incidence of breast cancer has increased in Mexico during last one decade, especially among older women, while the downturn observed in mortality mainly reflects improved survival as a result of earlier diagnosis and better cancer treatment.

  • Purpose: This study was conducted to analyze the annual trends and characteristics of work-related mental disorders including suicide among Korean workers. Methods: Employing the Industrial Accident Compensation Insurance (IACI) data collected by the Korea Worker's Compensation & Welfare Service, we analyzed total work-related mental disorders and suicide cases (n=455) claimed to IACI from 2008 to 2012. We paid a special attention to workers' socioeconomic status and occupational characteristics. Results: The number of injured workers and industrial accident rate decreased during the study period, whereas the case of work-related mental disorders showed significant increase. Mental disorders cases were more prevalent in workers who were male, aged the 40s, and engaged in finance, as well as with 1-5 years of working duration than their respective counterparts. Increasing trend of suicide cases was statistically significant by the Cochran-Mantel-Haenszel test (p=.002). Conclusion: This study suggests that work-related mental disorder management strategy and system should be established.
