This study seeks to investigate Key Audit Matters (KAMs) reporting of Thai listed companies in Thailand, and examines the influence of KAMs reporting on corporate financial performance. Data were collected from 180 companies listed in Thailand during 2016 to 2018, which accounted to 540 annual reports. KAMs reporting was quantified by content analysis from the audit reports, while financial performance and corporate characteristics were collected from the corporate annual reports. Descriptive analysis and multiple regressions were performed to analyze the data. The study results reveal that there was an increasing of KAMs reporting in audit report of listed companies in Thailand in terms of both number of issues and number of words across the observed period. The regression analysis indicates that was a significant and negative influence of words counted as KAMs reporting on financial performance, while there was no influence of KAMs reporting issue on the performance. Moreover, there was a negative relationship between corporate complexity and financial performance, while audit type had a positive correlation with financial performance. This study shows significant contribution on the implication of KAMs in an emerging economy and the role of KAMs as a communication device between auditor and stakeholders.

AI (Artificial Intelligence) has attracted interest as a key element for technological advancement in various fields. In Korea, internet companies are leading the development of AI business technology. Active government funding plans for AI technology has also drawn interest. But not everyone is optimistic about AI. Both positive and negative opinions coexist about AI. However, attempts on analyzing people's opinions about AI in a quantitative way was scarce. In this study, we used text mining on SNS (Social Networking Service) to collect opinions about AI. And then we performed a comparative analysis about whether people view it as a positive thing or a negative thing and performed a comparative analysis to recognize popular key-words. Based on the results, it was confirmed that the change of key-words and negative posts have increased through time. And through these results, we were able to predict trend about AI.

The production and decomposition rate of litters of major forest trees in Korea, such as Quercus acutissima, Quercus mogolica Robinia pseudoacacia Pinus rigida, Pinus thunbergiana, Abies koreana,Phy'llostackys reticulata, were estimated by Olson model. The amount of mineral nutrients in litters and soil were measured, and the relationships among them were studied. The annual litter production was the most in the forest of broadleaved deciduous trees and the least in the forest of monocotyledonous trees. The decomposition rate of broadleaved deciduous litters was higher than that of coniferous litters and lower than that of R. pseudoacacia litters. The time required for the decomposition of half of the accumulated organic matter of R.pseudoacacia litter, Quercus litter, P. rigida litter, Ph. reticulata litter, P. thunbergiana litter and .4.koreana litter in the forest stands were 1.263 years, 2.290~2.365 years, 2.644 years, 4.660 years,4.750 years, 6.699 years respectively. The amounts of N in litters and the amounts of N returned to the soil in the forests of R. pseudoacacia. Quercus, Pinus were proportional to the decay rate of organic matter. Key words: Annual litter production, Decomposition rate.

To estimate removal rate of phosphorus in aquatic grassland ecosystems of Paldangho, this investigation was conducted along with the coast of a lake. The experimental results may be summarized on communities of Typha angustata, Miscanthus sacchriflorus Phragmites communis and Scirpus tabernaemontani as follows. The annual production of phosphorus for the litters in T. angustata, M saccharsflorus, P. cam-munis and S. taiernaemontani grasslands were 10.252 g /$m^2$, 3.833 g /$m^2$, , 2.656 g /$m^2$, and 5.210 g /$m^2$, respectively. The ratio of annual production of P accumulated on surface soils in a steady state provides estimates of the removal rate r, The estimated removal rates r of P were 0.58, 0.78, 0.68 and 0.59 in T. angustata, M. sacchariflorus, P. communis and S. tabernaemontani grasslands re- spectively. The removal and accumulation of 50, 95 and of 99% of its steady state level, the estimates for P of T. angustata were 1.195, 5.173 and 8.623 years, in M. sacchariflorus were 0.880, 3.842, and 6.403 years, and in P. cammunis were 1.014, 4.390, and 7.316 years respectively, In S. tabernaemontani grassland required period were 1.178,5.099 and 8.500. Key words:T. angustata, S. tabernaemantani, P. communis, S. tabernaemontani, Paldangho, Removal rate, Phosphorus.

This study was performed to find out the mineral cycles of sulphur in dynamic grassland ecosystems in a steady state condition at the northwest side on Mt. Kwanak. The experimental results may be summarized on the communities of a Zoysia japonica and a Miscanthus sinensis as follows. As compared with some properties of the surface soils among two semi-natural grasslands, sulphur war greater quantity in a Miscanthus sinensis than in a Zoysia japonica on Mt. Kwanak . For the case of steady production and release, the raion of annual mineral production to the amount accumulated on the top of mineral soil in a steady state provides the estimates of release constant k. The release constants on sulphur of the litter were 0.54 in a Zoysia japonica and 0.36 in a Miscanthus sinensis grassland. The half times of S required for the release or accumulation of the litter on the grassland were 1.28 years in a Zoysia japonica and 1.93 years in a Miscauthus sinensis The amounts of annual cycles for sulphur in the grassland ecosystem under the steady-state conditions were 20.65g /$m^2$ in a Zoysia japonica and 26.28g /$m^2$ in a Miacanthus sinensis grassland. Key words: Zoysia japonica Miscanthus sinensis Mt. Kwanak, Sulphur, Mineral cycles.

To elucidate the mineral cycles of potassium in a dynamic grassland ecosystem in a steady state condition, this investigation was cunducted along the northwest side on Mt. Kwanak. The exper-imental results may he summarized on communities of Z. japonica and M. sinensis as follows. As compared with some pronerties of the surface soils among two semi-natural grasslands, the levels of exchangeahle potassium were high in M. sinensis and low in Z. japonica. Contents of potassium for the litters of Z. japonica and M. sinensis were 1.69% and 2.51%, re-spectively. The annual production of potassium was 1.32 g /m$m^2$ in the Z. japonica grassland and 3. 08 g /m$m^2$in the M. sinensis grassland. For a case of steady production and release, the ratio of annual min- eral production to the amount accumulated on top of the mineral soil in a steady state provides estimates of the release constant k. The models of the release, accumulation and annual cycle of potassium in a grassland ecosystem are determined by the equation (1) to (3), respectively (Table 3). Since it requires a period of about each 0.693 /r, 3 /r and 5 /r years for the release and accumu-lation of 50, 95 and 99% of its steady-state level, the estimates for potassium in a dynamic grass-land ecosystem of Mt. Kwanak were 1.5, 6.6 and 11.0 years in the Z. japonica grassland, and were 2.7, 11.9 and 19.8 years in the M. sinensis grassland. The amounts of annual cycles for potassium in a grassland ecosystem under the steady-state conditions were 1.32 g /m$^2$ in the Z. japonica grassland and 3.08 g /$m^2$ in the M. sinensis grassland. Key words : ZQvsia japonica Ahscanthus sinensis, Mt. Kwanak, Potassium cycles.
