The study aims to identify factors that influence university and college students' entrepreneurial intentions in Vietnam's Mekong Delta region. The study examines entrepreneurship mindset, subjective norm, capital sources, concept development assistance, personality qualities, and perceived behavioral control of university support for a student's entrepreneurial aim. The research was conducted according to the quantitative method. The data was collected through an online survey with a sample size of 611 students from 19 universities and colleges in the Mekong Delta region. The methods that test the scale, including Cronbach Alpha Test, Structural Equation Modeling (SEM), are used to consider the correlation between the influence factors. The results of SEM analysis show that there are five main factors affecting students' entrepreneurial intention with decreasing level of influence, including the source of capital, perceived behavioral control, business development support, entrepreneurial attitude, and educational support. Besides, the results indicate that the subjective norm, personality traits, and concept development support have no impact on the intention of students toward entrepreneurship. The research also reveals that the entrepreneurial intention of students at universities and colleges has a positive relationship and is significantly affected by capital source and perceived behavioral control.

Project management is a current trend of management in the public sphere, based on different principles, methods and tools. The tools include information technologies providing control over time, cost, quality and planning process in order to ensure accountability to interested parties. The goal of the research was to examine the impact of the integration of information systems in project management of the public sphere on the quality of public governance and administration using the example of infrastructure projects involving the private sector in developing countries. The methodology of the research is based on the concepts of "digital-era governance" (DEG), "Information governance" and "project governance" to determine the effectiveness of information systems and technologies in the management of infrastructure projects in the public sphere. The data from the countries with Lower middle income (India, Indonesia, Philippines, Ukraine, Vietnam) and Upper middle income (Argentina, Brazil, China, Colombia, Mexico, Peru, Romania, Russian Federation, Thailand, Turkey) for 1996-2020 were used to study the effects of DEG. The results show two main trends in the countries with Lower middle income and Upper middle income. The first trend is the development of digital governance, the concept of "digital-era governance" through information systems and performance measurement of the governance system, forecasting of investment flows of infrastructure projects, measurement of payback and effectiveness parameters for investment management in the public sector, decision support. The second trend is the existence of systemic challenges related to corruption, social and institutional factors through the development of democracy in developing countries and the integration of NPM similar to developed countries. The confidence of interested parties, especially private investors, in public authorities is determined by other factors - the level of return on investment, risks and assignment of responsibility, probability of successful completion of the project. These data still remain limited for a wide range of project participants, including citizens.

In order to preserve water environment, Total Maximum Daily Load(TMDL) is used to manage the total amount of pollutant from various sources, and the annual average load of source is calculated by the unit load method. Determination of the unit load requires reliable data accumulation and analysis based on a reasonable estimation method. In this study, we propose a revised unit load estimation method by analyzing the unit load calculation procedure of National Institute of Environment Research(NIER) method. Both methods were tested using observed runoff ratio and water quality data of rice paddy fields. The estimated values with the respective NIER and revised NIER methods were highly correlated each other. However, the Event Mean Concentration(EMC) and the runoff ratio considered in the NIER method appeared to be influenced by rainfall classes, and the difference in unit load increases as the runoff and EMC increase. The error can be further increased when the EMC and runoff ratio are changed according to changes in rainfall patterns by climate change and change of agricultural activities. Therefore, it is recommended to calculate unit load by applying the revised NIER method reflecting the non point pollution runoff characteristics for different rainfall classes.

행정부, 입법부, 사법부 등의 국가기록물은 영구기록물로 관리가 필요하다. 범죄사건이 발생 시마다 사법부의 기록물은 참고자료로 빈번하게 대출되고 반납되는데, 영구기록물의 관리를 위해서는 기록물들의 사건등록, 이력조회, 대출/반납, 보존검색, 기록물 폐기관리가 이루어져야 한다. 최근의 유비쿼터스 정보화의 활용방안으로 RFID가 활용되고 있다. 본 논문에서는 RFID를 이용한 영구기록물에 태그를 부착하여 기록물을 등록 관리하고, 이력을 추적하고, 보존, 검색하기 위한 영구기록물의 현황 분석, S/W, H/W, 네트워크 설계, 유비쿼터스 RFID 영구기록관리시스템 설계를 한다. 900MHz 대역의 RFID 태그를 부착한 현장에서 적용되는 성능 실험과 추적실험 후에 영구기록관리시스템을 구축한다. 구축 실행 후에 관련 시스템과의 연계성, 보안성 분석과 포렌식 자료를 생성하고 개선효과를 분석한다. 본 논문의 연구를 통하여 국가기록물 관리에 유비쿼터스 정보화 기술 적용과 포렌식 기술 발전에 기여하게 될 것이다.

국립농업과학원 생물안전성과는 생명공학기술로 개발되는 작물(GM작물)의 안전성 평가 중 '성분분석에 의한 비교평가'에 참고자료로 활용할 수 있도록 기존 상업화 작물성분의 분석 데이터를 제공하는 "작물성분 DB"를 구축하였다. "작물성분 DB"는 우리나라의 자연 환경에서 재배되는 주요 작물 품종들의 영양성분 함량정보를 제공함으로써 품종과 재배 지역, 연도에 따라 함량의 변화 정도를 확인할 수 있도록 데이터를 업그레이드 하고 있다. 현재 2곳 이상의 재배지역에서 2년 이상 재배한 벼와 고추 시료에 대한 주요 영양분과 항영양소, 2차 대사산물을 검증된 분석 방법을 사용하여 분석한 데이트를 제공하고 있다. 데이터는 평균값과 최저, 최대값을 제공함으로써 GM작물의 안전성 평가시 GM작물과 대응 비교작물 간에 나타나는 통계적 차이가 기존 상업작물의 생물학적 차이 또는 허용범위 내에 속하는지를 평가할 수 있도록 하였다. "작물성분 DB"는 사용자가 선택한 쿼리를 기반으로 쉽게 검색하고 활용하도록 하고 있다. 또한 유색미와 감자, 고구마, 콜리플라워와 같은 유색 작물의 기능성 성분 함량 정보를 제공하고 있어 일반 소비자들도 유용하게 정보를 활용할 수 있다. 본 논문은 상업작물 성분에 대한 중요한 정보를 제공하는 농진청 "작물성분 DB"의 구성과 사용법을 소개하였다.

농업관측에서의 다중분광 드론은 식생구분 및 식생활력도 분석에 있어 복사량이나 반사도와 같은 물리량을 기반으로 한 정량적이고 신뢰성 있는 데이터가 필요하다. 작황분석 모니터링을 위한 원격탐사 자료의 경우 동일지역에 대해 여러 시기에 걸쳐 촬영된 영상이 요구되며, 특히 엽면적 지수 또는 엽록소와 같은 생물리자료의 경우 동일한 기준에서의 시계열 자료를 통해 분석되므로 직접적으로 비교 가능한 반사도 자료가 필요하다. 드론영상을 기반 정사영상(정합영상)은 전체 영상 화소값이 왜곡되거나 접합 경계면 화소값의 차이가 발생하여 정확한 물리량 산출에 한계를 가진다. 본 연구는 시계열 작황 모니터링을 위한 드론영상의 보정방법에 따른 지상 반사도와 드론영상 기반 식생지수를 산정하고 그 결과를 지상관측자료와 비교하여 전처리 방법에 따른 드론영상의 분광학적 특성을 구명하고자 수행하였다.
