연평균 일교통량(AADT)은 교통 및 도로부문에서 중요한 기초자료로 활용되지만 예산 제약 등의 한계로 인해 일부 지점에 대해서만 상시조사를 통해서 AADT를 산출하고 있으며, 대다수의 지점에서는 단기 교통량 조사에서 수집된 샘플자료를 이용하여 AADT를 추정 활용하고 있다. 현재 단기 교통량 조사지점의 AADT 추정을 위하여 조사된 자료를 단순 평균하는 방법이 적용되고 있다. 기존 AADT 추정모형은 보정계수를 적용하는 방법이 대표적인 방법이나, 이 방법은 단기 교통량 조사 지점이 어떤 상시조사 지점의 보정계수를 적용할지에 대한 객관적인 방법이 없어 한계가 있다. 이에 본 연구에서는 공간통계모형을 도입하여 교통량 자료의 공간상관관계를 분석하고, 크리깅 모형을 적용하여 AADT를 추정하는 방법에 대하여 알아보았다. 공간통계모형의 AADT 추정의 정확도를 기존 연구와 비교하기 위하여 동일 대구간의 상시조사 지점의 보정계수를 적용하는 방법(방법 1)과 보정계수 그룹핑을 이용하여 해당 그룹의 보정계수를 적용하는 방법(방법 2), 공동크리깅을 적용한 방법(방법 3)을 비교분석하였다. 분석결과 공동크리깅을 적용한 모형은 기존 모형에 비해 AADT 추정 정확도가 향상되는 것으로 나타났다.

This study is conducted to determine the damage, distinguish the types and identify the restoration by that type for 13 Korea national parks out of 21. There are 21 Korea national parks are in Korea covering 6.67% of the country or $6,656km^2$ ($3,902km^2$ on land and $2,754km^2$ in the sea) currently since the area around Jirisan ($440km^2$) was designated as the first Korea national parks in 1967. With the cancellation of entrance admission on Korea national parks since 2007, annual visitors to the Korea national parks have grown from 37 millions in 2008 to 46 millions by 2013 and continue to grow due to numerous leisure activities, alpine activities and social changes. As such, Korea national parks are natural resource with high value to be conserved and are attracting significant attention as recreational spaces for people at the same time. On the other hand, there have been issues of soil erosions or disturbed vegetation due to increased number of visitor to the national parks. Korea national parks area damage to its type and damage characteristics to analyse the 13 Korea national parks out of 21 on July 2012 March, Korea national parks over the subjects of the National Park from damaged area status Survey analysis by the Korea National Park Service. As a result, 203 million units in the 16 Korea national parks damaged land of the reform package during ecological trail (including non-regular hiking trails) 153 (77.66%), damaged valleys 20(9.14%) independent damaged area, 13 disconnected ecological axis(7.61%), closed trail(2.03%) (3.55%), and line type damage(like a non-regular hiking trails) appears to be a high ratio. Korea national parks damaged land of the results identified, by contrast ratio and the annual number of visitors Bukhansan national park(49.26%), Gyeongju national park(23.65%) damaged land rates, such as Seorasan national park(4.93%), Songnisan national park (4.43 %), Gyeryongsan national park(3.45%), and the annual number of visitors be similar result. The National Park Service has been reporting on damages and restorations but damages and their types have not been established yet. Damages have been generally studied and categorized on hiking trails due caused by heavy traffic on them but the reports were limited on hiking trails only. Since damage to the Korea national parks are not limited on the hiking trails, it is necessary to determine damages in various aspects. Thus, in this study, damage types, spatial characteristics, causes and restorations are analyzed based on the survey results of damages to national parks in order to provide a basis for the efficient management and operation of the Korea national parks.

의료 목적으로 X선 촬영이나 CT, PET과 같은 진단방사선 피폭은 불가피하지만 선진국에서 의료 방사선이 최대의 인공 피폭원을 구성하고 있고 또 빠르게 증가하는 경향에 있음을 고려하면 의료상 피폭의 특성이나 그 결과로 인한 환자 선량 크기를 이해하는 것은 매우 중요하다. 이에 2002년도를 기준으로 단위 진료행위별 선량과 국내 의료보험 통계자료를 결합하여 방사선 진료절차별 집단선량과 1인당 유효선량 평가하였다. 절차의 유효선량 값은 NRPB 보고서, ICRP 80, MIRDOSE3.1 및 우리가 독립적으로 산출한 자료들로부터 편집하였다. 평가 결과 연간 집단선량은 진단방사선 22880man-Sv, 핵의학 4560man-Sv로서 총 27440 man-Sv로 나타났으며 따라서 인구 4770만 명을 나눈 1인당 연평균 의료상 피폭선량은 0.58mSv였다. 이 집단선량은 2002년 16기의 원전을 가동한 우리나라의 직업상피폭 70man-Sv보다 크게 많다. 특히 CT 촬영만의 집단선량도 9960man-Sv에 이름은 주목할 일이다. 이 결과는 국가의 방사선방호 정책이 의료에서 환자선량 최적화에 보다 주목해야 함을 시사한다.

Purpose: The annual statistics for poisoning are reported based on the data from poison control centers in many advanced countries. In 2016 a study was conducted to analyze the 2016 Korea Poisoning status. This study was conducted to make a better annual report for poisoning statistics in Korea from a 2017-2018 national representative database. Methods: This study was a retrospective analysis of poisoning patients based on the data from an emergency department (ED) based injury in-depth surveillance project by the Korea Centers for Disease Control and Prevention in 2017-2018. Bite or sting injuries were not included. Results: A total of 17714 patients presented to 23 EDs because of poisoning. Adults above 20 years old age accounted for 84.6% of the population, while the proportion of intentional poisoning was 60.8%. The poisoning substance presented in the ED were therapeutic drugs (51.2%), gas (20.3%), pesticides (16.4%), and artificial substances (11.4%). Overall, 35% of patients were admitted for further treatment. The mortality was 2.4% (422 cases), and the most common fatal substances in order were carbon monoxide, other herbicides, and paraquat. Conclusion: This study showed the 2017-2018 status of poisoning in Korea. The prognosis is different from the cause of poisoning and the initial mental state of the patient. Therefore, appropriate methods for preventing poisoning and therapeutic plans in specific situations are needed.

The more liquid the capital market, the more attractive it will be for investors to place their money in the capital market. Therefore, the purpose of this study is to investigate the factors that influence stock liquidity of manufacturing sector companies listed on the stock exchange in Indonesia. The independent variables used in this study are forward-looking information disclosure, institutional ownership, foreign ownership, and board activity with information asymmetry as an intervening variable and stock liquidity as the dependent variable. The population of this study is manufacturing sector companies listed on the Indonesian stock exchange (IDX). Samples are selected based on the random sampling method, and the number of samples is calculated based on the Slovin formula. The sample was 59 manufacturers, and data was annual reports (for 2 years) and stock transactions from 2016 to 2017. The results of the study showed that forward-looking information disclosure had a significant effect on information asymmetry. Information asymmetry and foreign ownership have a significant impact on stock liquidity, whereas information asymmetry mediates the relationship between forward-looking disclosures and stock liquidity. Furthermore, the accuracy of information about the certainty of business activity both now and in the future can instill confidence in stakeholders in interacting and cooperating.

The objective of this paper is to explore how board gender diversity affects corporate sustainability performance. Therefore, this paper examines the direct association between board gender diversity with corporate sustainability performance and the mediation effect of enterprise risk management (ERM) on this association. The study employed a cross-sectional survey method. Data were collected from annual reports, websites, and through the questionnaires that were distributed to Chief Financial Officers (CFOs) of all the listed companies of Dhaka Stock Exchange, Bangladesh. The partial least square technique of Structural Equation Modelling (SEM) approach was employed for data analysis. The result did not find support for the direct association between board gender diversity and sustainability performance in Bangladesh context. This implies that contextual factors, such as, male-dominant board, appointment of female directors based on family ties, lack of education and expertise etc. may discount gender diversity direct influence on sustainability performance. However, the study finds strong support for the mediating role of ERM use within the corporate structure. Further analysis of indirect effect suggests that ERM use mediates the relationship of board gender diversity and sustainability performance in full. This implies that in the Bangladesh context effective use of ERM is highly recommended.

This paper investigates the potential impact of external factors on bid/no-bid decision for supervision consultant service on construction project in Hanoi, the capital of Vietnam. The data used in this study are secondary data taken from annual reports and sourced from the Department of Public Procurement, Ministry of Planning and Investment in Hanoi. Besides, to identify the impact of external factors on bid/no-bid decision for supervision consultant service on construction project in Hanoi, the study collected data from 272 qualified questionnaires from bidders doing business in Hanoi. Cronbach's Alpha, EFA and regression model are used to explore the impact of each independent variable on bid/no-bid decision for supervision consultant service on construction project. The results show that three external determinants, including Project characteristic (PC), Legal codes (LC) and Competition (C) are affecting bid/no-bid decision for supervision consultant service on construction project in Hanoi. Among them, Project characteristic (PC) and Legal codes (LC) have positive relationships with bid/no-bid decision for supervision consultant service on construction project, whereas Competition (C) negatively affects bid/no-bid decision for supervision consultant service on construction project. It means the more contractors actually participate in a bid, the less bid/ no-bid decisions are made.

Purpose - The purpose of this study is to find out the intellectual capital disclosure (ICD) and its determinants in the pharmaceutical and chemical industry of Bangladesh. Research design, data, and methodology - This research study is conducted on the listed firms of pharmaceutical and chemical industry in Bangladesh during the period of 2016 to 2017. This study develops a self-structured intellectual capital disclosure index; and the proxies of determinants of ICD are used as board characteristics (board size, independent directors and female directors), ownership structures (institutional ownership and director ownership), and firm characteristics (firm size, leverage and performance). The study uses a content analysis to analyze the extent of ICD and a pooled cross-sectional method to find the determinants of ICD. Research Findings - This study finds that intellectual capital disclosure is positively associated with firm size, leverage, and firm performance and negatively associated with director ownership and institutional ownership. This study also finds that there is no significant association of ICD with independent director or female director. Conclusions - The study recommends that the regulatory authority should develop mandatory guidelines on ICD for ensuring proper and consistent disclosure about the intellectual capitals. Besides, the companies should include a separate section in the annual reports to disclose the measurement and management of intellectual capital.
