  • Purpose: The purpose of this study is to identify research trends related to ESG by domestic and overseas researchers so far, and to present research directions and clues for the possibility of applying ESG to Korean companies in the future and ESG practice through comparison of derived topics. Research design, data and methodology: In this study, as of October 20, 2022, after searching for the keyword 'ESG' in 'scienceON', 341 domestic papers with English abstracts and 1,173 overseas papers were extracted. For analysis, word frequency analysis, word co-occurrence frequency analysis, BERTopic, LDA, and OLS regression analysis were performed to confirm trends for each topic using Python 3.7. Results: As a result of word frequency analysis, It was found that words such as management, company, performance, and value were commonly used in both domestic and overseas papers. In domestic papers, words such as activity and responsibility, and in overseas papers, words such as sustainability, impact, and development were included in the top 20 words. As a result of analyzing the co-occurrence frequency of words, it was confirmed that domestic papers were related mainly to words such as company, management, and activity, and overseas papers were related to words such as investment, sustainability, and performance. As a result of topic modeling, 3 topics such as named ESG from the corporate perspective were derived for domestic papers, and a total of 7 topics such as named sustainable investment for overseas papers were derived. As a result of the annual trend analysis, each topic did not show a relatively increasing or decreasing tendency, confirming that all topics were neutral. Conclusions: The results of this study confirmed that although it is desirable that domestic papers have recently started research on consumers, the subject diversity is lower than that of overseas papers. Therefore, it is suggested that future research needs to approach various topics such as forecasting future risks related to ESG and corporate evaluation methods.

  • Long term water quality change was analyzed to evaluate the effect of the Total Maximum Daily Load (TMDL) policy. A trend analysis was performed for biochemical oxygen demand (BOD) and total phosphorus (TP) concentrations data monitored at the outlets of the total 41 TMDL unit watersheds of the Nakdong River in the Republic of Korea. Because water quality data do not usually follow a normal distribution, a nonparametric statistical trend analysis method was used. The monthly mean values of BOD and TP for the period between 2004 and 2015 were analyzed by the seasonal Mann-Kendall test and the locally weighted scatterplot smoother (LOWESS). The TMDL policy effect on the water quality change of each unit watershed was analyzed together with the results of the trend analysis. From the seasonal Mann-Kendall test results, it was found that for BOD, 7.8 % of the 41 points showed downward trends, 26.8 % and the rest 65.9% showed upward and no trends. For TP, 51.2% showed no trends and the rest 48.8% showed downward trends. From the LOWESS analysis results, TP began to decrease in most of the unit watersheds from mid-2010s when intensive chemical treatment processes were introduced to existing wastewater treatment plants. Overall, for BOD, relatively more points were improved in the main stream compared to the points of the tributaries although overall trends were mostly no trend or upward. For TP, about half of the points were improved and the rest showed no trends.

  • 본 논문은 조직유효성에 대한 최근 20여년간의 주요 연구 동향을 파악하는데 있다. 이에 Elsevier에서 제공하는 해외 학술 데이터베이스인 SCOPUS를 활용하여 최근 24년간(2000~2023) 조직유효성의 연구 동향을 파악하였다. 빈도 분석결과, organizational 2,789건, effectiveness 2,714건, management 850건, performance 689건, organizations 632건, leadership 597건 순으로 나타났다. 트랜드 분석 결과. effectiveness와 organizational은 꾸준하게 연구가 진행되고 있으나, leadership, management의 트랜드는 최근 들어서는 다소 감소하고 있는 것으로 나타났다. LDA 분석 결과 effectiveness와 organizational이 중요한 토픽으로 나타났는데, 이는 현재와 같이 미래를 예측하기 어려울 때 사전에 예측하는 능력이 중요하다는 것을 보여주고 있다. 본 연구결과는 기업에서 전략적인 차원으로 조직의 운영방안을 수립하고 이를 통해 조직의 유효성을 높이는데 있어 지침으로 활용이 가능할 것으로 보인다.

  • An analysis of the changing trends of kyongjobi expenditure pattern from 1982 to 1996 and the related factors of kyongjobi expenditure of urban household in 1996 has been performed. Major findings were as follow: An average monthly expenditure was 20,036 won during the period, and the increased rate of monthly expenditure was 5.6 times in the past 15 years which was the twice as much as of the total consumption. The ratio of the total kyongjobi consumption was increased about 2 times during the period, and it was 2.96% in 1996. During the period, an average marginal consumption propensity was 0.0379, and it was dramatically increased from '93 to '94. Average income elasticity was 1.743 during the period and found out that it was luxury goods. The result of Anova and Tobit analysis showed that the level of consumption, number of earners, age and education had positive effect on kyongjobi. And in Seoul area, house owner, male(head of the household), and professionals spent more on kyongjobi than other.

  • Objectives: Prompt detection is a cornerstone in the control and prevention of infectious diseases. The Integrated Disease Surveillance Project of India identifies outbreaks, but it does not exactly predict outbreaks. This study was conducted to assess temporal correlation between Google Trends and Integrated Disease Surveillance Programme (IDSP) data and to determine the feasibility of using Google Trends for the prediction of outbreaks or epidemics. Methods: The Google search queries related to malaria, dengue fever, chikungunya, and enteric fever for Chandigarh union territory and Haryana state of India in 2016 were extracted and compared with presumptive form data of the IDSP. Spearman correlation and scatter plots were used to depict the statistical relationship between the two datasets. Time trend plots were constructed to assess the correlation between Google search trends and disease notification under the IDSP. Results: Temporal correlation was observed between the IDSP reporting and Google search trends. Time series analysis of the Google Trends showed strong correlation with the IDSP data with a lag of -2 to -3 weeks for chikungunya and dengue fever in Chandigarh (r > 0.80) and Haryana (r > 0.70). Malaria and enteric fever showed a lag period of -2 to -3 weeks with moderate correlation. Conclusions: Similar results were obtained when applying the results of previous studies to specific diseases, and it is considered that many other diseases should be studied at the national and sub-national levels.
