In this study, we collected and analyzed domestic and international studies related to watersheds in the forest sector. Keyword co-occurrence analysis was conducted using the VOSviewer program to identify the research areas of domestic and international studies and the network structure to compare research trends. As a result, the number of research articles in international watershed-related studies showed an overall increasing trend, and the research areas were diverse and located close to each other, indicating that many convergence studies were conducted. On the other hand, the number of papers in domestic watershed-related studies seems to have stagnated overall from the past to the present, and the research areas are mainly focused on forest disasters and hydrology, with limited interdisciplinary convergence studies. In addition, in both domestic and international studies, watersheds are currently mentioned as research sites rather than management or analysis units in the forest sector. It is important to actively promote interdisciplinary research in Korea to provide a scientific and balanced basis for watershed-level forest management planning.

As FTAs are introduced, greater trade between the countries results in more disputes between parties to the agreement. Disputes in international trade have previously been settled mainly through international arbitration. However, with the recent rise in negative aspects of the arbitration system, the international community has begun to seek ways to utilize mediation for replacing the arbitration system. Mediation is a dispute settlement system that helps the parties settle their disputes on their own through negotiations. The UNCITRAL, which seeks to unify and develop international trade law, amended the Model Mediation Law in 2018 and adopted the 'United Nations Convention on International Settlement Agreements Resulting from Mediation' in August 2019 to enable the adoption of the international settlement agreement. This study analyzes the main contents of the 2018 Model Mediation Law and predicts the potential for the development of international commercial mediation as a dispute settlement procedure for future international trade.

BLUs are major component in LCD industry which occupies 90% or more of FPD market worldwide and BLU market is expected to be expanded continuously according to the trend of miniaturization, slimness, low power consumption and low weight. The larger the BLU market scale, the more important standardization of performance evaluation techniques to clearly prescribe the product specification. Currently the government is promoting the establishment of related laws and coincidence with international standards to cope with agreements such as WTO/TBT, but the nongovernmental standardization activities are not enough to be actualized. Furthermore, BLU related components such as CCFL, EEFL, inverter and reflector are already developed for localization to substitute imports with home products but collective standardization, national standardization, and international standardization are still not done. So, performance specifications and evaluation methods for normal fluorescent lamps or industrial lamps are being adopted and used as national standards and safety certification standards instead. Making these standards enables to prepare a chance to penetrate into global market and to promote world best products. Also, by making this collective standard, it provides chances to take part in international standardization activities, to protect domestic industries and technologies, to obtain the trend of advanced technologies, and to be predominant over other countries. That is to say, CCFL standardization helps raise 21st century national strategic technology policy and go ahead of globalization of core technologies.

In a typical trend-cycle decomposition of GDP, the trend component is usually assumed to follow a random walk process. This paper considers an ARIMA trend and assesses the validity of the ARIMA trend model. I construct univariate and bivariate unobserved-components(UC) models, allowing the ARIMA trend. Estimation results using U.S. data are favorable to the ARIMA trend models. I, also, compare the forecasting performance of the UC models. Dynamic pseudo-out-of-sample forecasting exercises are implemented with recursive estimations. I find that the bivariate model outperforms the univariate model, the smoothed estimates of trend and cycle components deliver smaller forecasting errors compared to the filtered estimates, and, most importantly, allowing for the ARIMA trend can lead to statistically significant gains in forecast accuracy, providing support for the ARIMA trend model. It is worthy of notice that trend shocks play the main source of the output fluctuation if the ARIMA trend is allowed in the UC model.

Scheduling is one of the main functions in construction project to determine the sequence of activities necessary to complete a project. The scheduling techniques provide important information crucial to a project's success. Highway construction project the paving activity can be considered a linear activity. Linear scheduling technique may be better suited for linear projects than other scheduling techniques. A new type of scheduling in linear project is calling Linear Scheduling Model (LSM). The Project monitoring and controlling is very ease to identify that all the stage of linear project and have more advantages.

Major accidents such as typhoon, tsunami, and chemical accidents have been continuously occurred. In this environment, Technical Commitment (TC) related to disaster management part in the International Organization for Standardization (ISO) concentrates their efforts to enact the business continuous management in emergency situation for international standard. As a result of TC223, four international standards are enacted in 2011, 2012. In the Korean industrial standard, two international standard (ISO22300, ISO22301) out of four standards were enacted in 2012. This study analyzes a recent trend and proposes a method activating of international societal security standard for chemical accidents. Disaster certificate system for developing disaster safety industry is suggested. We hope each related organization could develop our disaster safety management policy and research based on this study.

The study analyzed bibliometric data of papers published in Korea Citation Index (KCI) and Web of Science (WoS) journals from 2002 to 2021. After examining size differences of KCI and WoS domains in the number of authors, institutions, and journals to put publication and citations counts in perspective, the study investigated co-authorship patterns over time to compare collaboration trends of Korean and international scholars and analyzed the data at author, institution, and journal levels to explore how the influences of authors, institutions, and journals on research output differ across domains. The study also conducted frequency-based analysis of keywords to identify key topics and visualized keyword clusters to examine topic trends. The result showed Korean LIS authors to be twice as productive as international authors but much less impactful and Korean institutions to be at comparable levels of productivity and impact in contrast to much of productivity and impact concentrated in top international institutions. Citations to journals exhibited initially increasing pattern followed by a decreasing trend though WoS journals showed far more variance than KCI journals. Co-authorship trends were much more pronounced among international publication, where larger collaboration groups suggested multi-disciplinary and complex nature of international LIS research. Keyword analysis found continuing diversification of topics in international research compared to relatively static topic trend in Korea. Keyword visualization showed WoS keyword clusters to be much denser and diverse than KCI clusters. In addition, key keyword clusters of WoS were quite different from each other unlike KCI clusters which were similar.

Purpose - The purpose of this study examines when the optimism impact on financial asset price forecasting and the boundary condition of optimism in the financial asset price forecasting. People generally tend to optimistically forecast their future. Optimism is a nature of human beings and optimistic forecasting observed in daily life. But is it always observed in financial asset price forecasting? In this study, two factors were focused on considering whether the optimism that people have applied to predicting future performance of financial investment products (e.g., mutual fund). First, this study examined whether the degree of optimism varied depending on the direction of the prior price trend. Second, this study examined whether the degree of optimism varied according to the forecast period by dividing the future forecasted by people into three time horizon based on forecast period. Research design, data, and methodology - 2 (prior price trend: rising-up trend vs falling-down trend) × 3 (forecast time horizon: short term vs medium term vs long term) experimental design was used. Prior price trend was used between subject and forecast time horizon was used within subject design. 169 undergraduate students participated in the experiment. χ² analysis was used. In this study, prior price trend divided into two types: rising-up trend versus falling-down trend. Forecast time horizon divided into three types: short term (after one month), medium term (after one year), and long term (after five years). Results - Optimistic price forecasting and boundary condition was found. Participants who were exposed to falling-down trend did not make optimistic predictions in the short term, but over time they tended to be more optimistic about the future in the medium term and long term. However, participants who were exposed to rising-up trend were over-optimistic in the short term, but over time, less optimistic in the medium and long term. Optimistic price forecasting was found when participants forecasted in the long term. Exposure to prior price trends (rising-up trend vs falling-down trend) was a boundary condition of optimistic price forecasting. Conclusions - The results indicated that individuals were more likely to be impacted by prior price tends in the short term time horizon, while being optimistic in the long term time horizon.

The purpose of this study lies in touching the study trend of Chinese education technology through the analysis on present situation of the study in Chinese education technology, and is to suggest the direction for the its further study and development. In order to achieve these kinds of study purpose, the frames have been set to grasp the features and trend of Chinese educational technology in such as 4 aspects of educational technology definition, curriculum and the cultivation of genuine individuals, study zone aspect and the method, and in order to grasp, in the comparison with the countries of advanced educational technology such as Korea, America etc., the progressive features and the trend of development of Chinese educational technology have been analyzed. As a result of the analysis, it has been found that Chinese educational technology has the different features in the study and development of educational technology of Korea and America in the abovementioned 4aspects. First, in the education technology comprehension, it differs from Korea, Japan and America, and understands the technology as a skill. Consequently, in either study or actuality, it seems puts more emphasis on skills (moreover, the aspect of hardware). Second, in the aspect of curriculum and the cultivation of the genuine individuals, gives preponderance to science aspect, and the unclear distinction between the education technology and the computer science makes that the true character of educational technology is not clear. Third, when speaking of study fields and study methods, those of china is a little behind of the advanced nations of the educational engineering, Korea, America and so on. And in the range of study, China is following the international tendency but when it comes to the depth of study and quality is very far from perfect. In the aspect of study method, the theoretical study, design study and development study are occupying mostly, and it is hardly to see the existence about actual proof study, and in this aspect, it is quite different than that of Korea and America. And it is judged that it is related with the traditional educational ideology and the academic study tradition, the cultural air and the features of economical development of China.
