A recent study conducted by KOTI reported that regional and urban read congestion costs in Korea are continually rising in the ranges between 3.1% thru 4.1% of GDP in the every respective year during the past 10 years. The report explicates that the congestion problem has motivated sharp raise of the logistics expenditure from 4.4% of GDP in the year of 1998 to 16% in the year of 2003. Even though, the government has allotted annual budget in the ranges between 2.7% and 3.7% of GDP to the SOC investment for the consecutive years of past decade, the amounts are however far less and insufficient to meet with social requirements and its demands. The cost of logistics has been excessively went up much higher rate than that of other industries and that of 9.6% in Japan and United States respectively It is obvious that the high logistics cost could be a detrimental factor to fierce emulation with others in the global trade market. Therefore it is an essential matter to eliminate or exclude all the probable sources that might cause or create extra costs on logistics. In consideration of such situation in Korea, the SOC investment with private capital could be a best cogitable scheme to acquire its prompt demand solutions and stimulate the emulation ability in the international trade market what's more betterment for all of our quality life in the near future.

Corporate social responsibility is an inevitable trend in the global context. It is the responsibility of the organizations to the community and society to ensure the fairness of the interests of stakeholders. This is an issue that deserves attention, not in the national or regional level, but as a global issue. The purpose of article is to examine the effect of corporate governance on corporate social responsibility disclosure of 155 samples of 31 Vietnamese commercial banks from 2015 to 2019. The data of this study is employing time-series data and used the ordinary least squares to test the model. The results show that there are three factors that positively affect corporate social responsibility disclosure, namely, board size, foreign members of board, and audit committee. Thereby, the article proposes that board of director in Vietnamese commercial banks needs to raise awareness about corporate social responsibility, and the Central bank of Vietnam should monitor the disclosure of information regularly with severe sanctions on commercial banks that do not comply with the regulations of corporate social responsibility disclosure. This contributes to improving the information quality of the banking sector to meet the trend of international economic integration.

The aim of this paper is to investigate the level of intellectual capital disclosure (ICD) in commercial banks listed on the Indonesian Stock Exchange. This paper also observed the effects of ICD and corporate governance mechanism on market value. This study uses content analysis techniques to measure ICD. The paper provides a novel approach to measure the ICD quality in developing countries using a four-numerical coding system. Secondary data were obtained from the financial statements and annual reports of the banks for the period 2011-2014. The data from 31 banks were analyzed using ordinary least square regression. The study reports that the quality of intellectual capital disclosure in Indonesian commercial banks increase steadily. Narrative disclosure dominates the report of intellectual capital in Indonesian banks. The results indicate that the size of audit committee, frequency of audit committee meeting, and intellectual capital disclosure affect positively the market value. Overall, the results indicate intellectual capital disclosure is associated with the market capitalization; these findings indicate that the ICD is a consideration in a stock investment decision. While regulations in Indonesia regarding intellectual capital reporting are not conclusive yet, the information needs of stakeholders have encouraged companies to expand voluntary disclosure.

This study aims to create a model for predicting the number of extinguishment manpower to put out forest fires by taking into account the climate, the situation, and the extent of the damage at the time of the forest fires. Past research has been approached to determine the cause of the forest fire or to predict the occurrence of a forest fire. How to deal with forest fires is also a very important part of how to deal with them, so predicting the number of extinguishment manpower is important. Therefore predicting the number of extinguishment manpower that have been put into the forest fire is something that can be presented as a new perspective. This study presents a model for predicting the number of extinguishment manpower inputs considering the scale of the damage with forest fire on a scale bigger than 0.1 ha as data based on the forest fire annual report(Korea Forest Service; KFS) from 2015 to 2018 using the moderated multiple regression analysis. As a result, weather factors and extinguished time considering the damage show that affect forest fire extinguishment manpower.

The purpose of this study is to provide against to the meteorological disasters in Korea caused by the typhoons by means of the statistical analyses for the relation between the intensities of the typhoons and the meteorological disasters. The data are extracted from the "TYPHOON REPORT OF KOREA" and the "TYPHOON WHITE BOOK" issued by the Central Meteorological Office. The results are summarized as follows : (1) The annual mean frequency and the total number of the typhoon causing the disasters during 30 years (1956∼1985) are 2.2, 65 respectively, and the highest number appears in August followed by September and the third is July. And the degrees of themeteorolgocal disasters are alsio the same order. (2) The more serious disasters occurred by the TS degree typhoons, and the TS degree typhoons occupy the highest frequency. (3) The more serious disasters occurred by the TS degree typhoons, and the TS degree typhoons occupy the highest frequency. (3) The meteorological disaster per typhoon is most severe in August, and the July and September are alike in the degree of the disasters per typhoon. (4) The meteorological disasters are approximately a proportional relation to the intensities of the typhoons. (5) The frequency of the Rain typhoon , Wind typhoon and Rain·Wind typhoon are about 2 : 1: 3 in July, August and September respectively. And the severe disasters occur more frequently by the Rain typhoon than by the Wind typhoon.

Purpose : The purpose of this study was to examine the degrees of turnover intention among Korean staff nurses(N=175) and to identify discriminating factors of their turnover intention. Method : The data were driven from a larger study and staff nurses who had worked more than 1 year as nurses were included in the analyses. The original data were collected from May 1999 to March 2000. Descriptive and discriminant analyses were utilized. Results : 87% of the participants reported turnover intention. Nurses were grouped into three group(GP)s depending on the frequencies of turnover intention: Never GP(N=23), Sometimes GP(N=107), Frequent GP(N=43). With three GPs, two functions were produced and only function 1 was significant that significantly discriminated Never and Frequent GPs. Additional discriminant analysis with only Never and Frequent GPs produced function classified 93% of the participants correctly into two GPs. Sub-dimensions of work satisfaction were significant discriminating factors. Nurses who are satisfied with doctor and nurse relationship, pay, and hospital administration tend to report no intention in turnover. Conclusion : Based on the findings of this study, possible managemental intervention for increasing interpersonal skills and assertiveness of nurses, inviting medical residents in ward team meeting, increasing incentives or baseline adjustment of annual income for registered nurses were suggested.

We report our measurements of the trigonometric distance and proper motion of IRAS 20056+3350, obtained from the annual parallax of $H_2O$ masers. Our distance of $D=4.69^{+0.65}_{-0.51}kpc$, which is 2.8 times larger than the near kinematic distance adopted in the literature, places IRAS 20056+3350 at the leading tip of the Local arm and proximal to the Solar circle. We estimated the proper motion of IRAS 20056+3350 to be (${\mu}_{\alpha}cos{\delta}$, ${\mu}_{\delta}$) = ($-2.62{\pm}0.33$, $-5.65{\pm}0.52$) $mas\;yr^{-1}$ from the group motion of $H_2O$ masers, and use our results to estimate the angular velocity of Galactic rotation at the Galactocentric distance of the Sun, ${\Omega}_0=29.75{\pm}2.29km\;s^{-1}kpc^{-1}$, which is consistent with the values obtained for other tangent points and Solar circle objects.
