Refining the monitoring and evaluation reporting is an important thing in e-Government. Indonesia which has had e-Government roadmap since 2000, has not had the systematic mechanism to monitor and evaluate e-Government in which the report can be easily accessed by the public and used to be the best practice to improve other e-Government implementation. Enterprise architecture (EA) has the major objective to straighten an enterprise to its necessary requirements. It can be used to propose the required system and that was the purpose of this paper. It was started by reviewing the literature about e-Government monitoring and evaluation, using quality of service as the means, and understanding TOGAF as one of EA framework. The second step was comparing EA and the evaluation of e-Government in Korea and Indonesia to get the best practices. And the last step was creating EA for the monitoring and evaluation reporting system based on Korea and the literature reviewed. It is expected that the formulized EA can be a tool to improve e-Government implementation in Indonesia.

The results of comparing $PM_{10}$ concentration between 'Namsan' and 'Yongsan-gu' air quality monitoring stations show similar values with averaged concentration in the whole Seoul. The correlation factors in both sites were 0.865, 0.828 in 2005, 2006, respectively. For 'Bukhansan' and 'Gangbuk-gu' air quality monitoring stations, different from the results mentioned above, they showed clear differences as altitude changes. PM10 concentration in 'Bukhansan' monitoring stations was 10 ${\mu}g/m^3$ lower than 'Gangbuk-gu' monitoring station which is located near the ground. Also, averaged PM10 concentration in 'Bukhansan' and 'Gangbuk-gu' monitoring stations was lower than that in the whole Seoul. When comparing $NO_2$ concentration between 'Namsan' and 'Yongsan-gu' monitoring stations, $NO_2$ concentration in 'Namsan' monitoring station was lower than 'Yongsan-gu' monitoring station. For $NO_2$ concentration in 'Bukhansan', 'Gangbuk-gu' and 'the whole Seoul', there were the same pattern in 'Gangbuk-gu' and the 'the whole Seoul' and low values in 'Bukhansan' monitoring station. The correlation factors of $NO_2$ concentration in 'Bukhansan' and 'Gangbukgu' was 0.525, 0.549 in 2005, 2006, respectively, which stands for low correlationship.

This study attempts to examine whether ownership of government-controlled corporations and audit committee effectiveness are related. The population of this study is 431 listed manufactured firms in the Saudi Stock Exchange (Tadawul) for the period 2012-2019 that published their financial and annual reports for the period 2012-2019. This population criterion is based on considerations that manufacturing companies listed on Tadawul have publicly accessible data and they have greater obligations to implement corporate governance code. Using the complementary hypothesis, this study predicts that there is a positive relationship between the ownership of government-controlled companies and audit committee effectiveness. The Pooled OLS regression shows that government-controlled companies' ownership is positively associated with audit committee effectiveness. Our study also indicates that ownership of government-controlled companies as a governance monitoring mechanism becomes more effective as it is combined with audit committee effectiveness which is another governance monitoring mechanism. The results of this study provide insightful evidence to policymakers at the company and country levels on the relationship of government-corporate ownership and audit committee effectiveness.

More than 70 percent of terrestrial territory of Korea is mountainous areas where degradation becomes serious year by year due to illegal tombs, expanding golf courses and stone mine development. We elaborate the potential usage of high resolution image for the monitoring of the phenomena. We made the classification of tombs and the statistical radiometric characteristics of graves were identified from this project. The graves could be classified to 4 groups from the field survey. As compared with grouping data after clustering and discriminant analysis, the two results coincided with each other. Object-oriented classification algorithm for feature extraction was theoretically researched in this project. And we did a pilot project, which was performed with mixed methods. That is, the conventional methods such as unsupervised and supervised classification were mixed up with the new method for feature extraction, object-oriented classification method. This methodology showed about $60\%$ classification accuracy for extracting tombs from satellite imagery. The extraction of tombs' geographical coordinates and graves themselves from satellite image was performed in this project. The stone mines and golf courses are extracted by NDVI and GVI. The accuracy of classification was around 89 percent. The location accuracy showed extraction of tombs from one-meter resolution image is cheaper and quicker way than GPS method. Finally we interviewed local government officers and made analyses on the current situation of mountainous area management and potential usage of KOMPSAT-II images. Based on the requirement analysis, we developed software, which is to management and monitoring system for mountainous area for local government.

Objectives: This study is intended to seek credible and efficient measurements on airborne asbestos concentrations that allow immediate action by establishing complementary data through comparative analysis with existing PCM and KF-100 method real-time monitoring equipment in working areas in Seoul where asbestos-containing buildings are being demolished, including living environment surroundings. Materials: We measured airborne asbestos concentrations using PCM and KF-100 at research institutes, monitoring networks, subway stations and demolition sites of asbestos-containing buildings. Through this measurement data and KF-100 performance testing, we drew a conversion factor and applied it via KF-100. Finally we verified the relationship between PCM and KF-100 with statistical methods. Results: The airborne asbestos concentrations by PCM for the objects of study were less than the detection limit(7 fiber/$mm^2$) in three (20%) out of 15 samples. The highest concentration was 0.009 f/cc. The airborne asbestos concentrations by PCM in laboratories, monitoring networks, subway stations and demolition sites of asbestos-containing buildings were respectively $0.002{\pm}0.000$ f/cc, $0.004{\pm}0.001$ f/cc, $0.009{\pm}0.001$ f/cc, and $0.002{\pm}0.000$ f/cc. As a result of KF-100 performance testson rooftops, the conversion factor was 0.1958. Applying the conversion factor to KF-100 for laboratories, the airborne asbestos concentrations ratio of the two ways was nearly 1:1.5($R^2$=0.8852). Also,the airborne asbestos concentration ratio of the two ways was nearly 1:1($R^2$=0.9071) for monitoring networks, subway stations, and demolition sites of asbestos-containing buildings. As a result of independent sample t-tests, there was no distinction between airborne asbestos concentrations monitored in the two ways. Conclusions: In working areas where asbestos-containing buildings are being demolished, including living environment surroundings, quickly and accurately monitoring airborne asbestos scattered in the air around the working area is highly important. For this, we believea mutual interface of existing PCM and a real-time monitoring equipment method is possible.

Air quality monitoring is a primary activity for industrial and social environment. The government identifies the pollutants that each industry must monitor. Especially, the VOCs (Volatile Organic Compounds), which are very harmful to human body and environment atmosphere, should be controlled under the government policy. However, the VOCs, which have not been confirmed in emission sources are very difficult to monitor. It is needed to develop the monitoring system that allow the continuous and in situ measurement of VOCs mixture in different environmental matrices. Gas chromatography and mass spectrometry are the most prevalent current techniques among those available for the analysis of VOCs. But, they need a large size analytical instrument, which costs a great deal for purchase and operation. In addition, it has some limitations for realtime environmental monitoring such as location problems and slow processing time. Recently, several companies have commercialized a portable VOCs measurement systems, which cannot classify various kinds of VOCs but total quantities. We have developed a VOCs measurement system, which recognizes various kinds and quantities of VOCs, such as benzene, toluene, and xylene (BTX). Also, it can be used as a stand- alone type and/or fixed type in the vehicle with rack for real -time environmental monitoring.

수질오염총량관리제는 유역에 설정된 오염물질 항목별 목표수질을 만족할 수 있도록 배출부하량을 총량적으로 관리하기 위해서 도입되었다. 그 동안 4대강 수계를 대상으로 수질오염총량관리제를 시행하면서 여러 가지 문제점이 발생되었다. 이러한 문제점들이 일부 보완되었지만, 아직도 중앙정부와 지방자치단체간의 역할에 대한 부분은 명확하게 정립되어 있지않다. 따라서 본 연구는 수질오염총량관리제의 효율적인 시행을 위한 중앙정부와 지방자치단체간의 역할을 제시하였다. 먼저, 중앙정부는 국가하천의 주요지점에 수질기준 및 대상항목을 포함하는 환경기준을 설정하고, 지방자치단체는 해당유역에서 대상항목의 목표수질을 설정해야 한다. 또한, 지방자치단체는 지류하천의 수질개선정도를 파악하기 위하여 하천의 수질 및 유량모니터링을 지속적으로 시행하여야 한다. 특히, 중앙정부의 유역환경청은 전체 수계를 대상으로 수질오염총량관리 기본계획을 수립하여야 하며, 지방자치단체는 목표수질을 초과하는 단위유역을 대상으로 시행계획을 수립하여야 한다. 수질 오염총량관리 이행평가는 기초자치단체에서 지류하천의 수질 및 유량을 모니터링을 통하여 매년마다 단위유역의 목표수질 만족여부 만을 평가해야 한다. 수질오염총량관리 이행평가보고서는 단위유역의 목표수질 초과에 대한 원인분석을 포함하여 계획기간 최종년도에 유역환경청에 제출하여야 한다.

Simultaneous monitoring in many locations is necessary to evaluate the air quality and analyze future trend of a city, For this purpose, it is essential to install air pollution monitoring network. The first automatic air pollution monitoring network was introduced Seoul in 1973. As of 1995, 20 monitoring stations are now in operation. Concerning the management of the air pollution monitoring network, there was some argument among the relavant scholars, non-governmental organization(NGO) and the government organization. So far, there was no extensive evaluation and analysis about the network. The purpose of this study was to evaluate the representativeness of air quality monitoring network through actual measurement of the concentration of the air pollutant. The concentration of NOx was extensively measured widely in Seoul area three times using the TEA simple measuring technique. Even the judgement level for the area representativeness was lowered to 80%, Ssangmun-dong monitoring station tend to overestimate the pollutant concentration of the covered area. While, Sinlimdong monitoring station tend to underestimate the pollutant concentration of the covered area.

We tested for residual pesticide levels in dried vegetables in Seoul, Korea. A total of 100 samples of 13 different types of agricultural products were analyzed by a gas chromatography-nitrogen phosphate detector (GC-NPD), an electron capture detector (GC-${\mu}ECD$), a mass spectrometry detector (GC-MSD), and a high performance liquid chromatography- ultraviolet detector (HPLC-UV). We used multi-analysis methods to analyze for 253 different pesticide types. Among the selected agricultural products, residual pesticides were detected in 11 samples, of which 2 samples (2.0%) exceeded the Korea Maximum Residue limits (MRLs). We detected pesticide residue in 6 of 9 analyzed dried pepper leaves and 1 sample exceeded the Korea MRLs. Data obtained were then used for estimating the potential health risks associated with the exposures to these pesticides. The estimated daily intakes (EDIs) range from 0.1% of the acceptable daily intake (ADI) for bifenthrin to 8.4% of the ADI for cadusafos. The most critical commodity is cadusafos in chwinamul, contributing 8.4% to the hazard index (HI). This results show that the detected pesticides could not be considered a serious public health problem. Nevertheless, an investigation into continuous monitoring is recommended.

Our paper shows the results of 302 samples of herb medicines about fungal contamination at Yakyeang markets in Seoul. The sample medicines were treated VICAM pretreatment and analysed by post column derivatisation procedure(PHRED-HPLC) with a fluorescence detector. Aflatoxin B1 was founded from 50.3% of samples, aflatoxin B2 was 39.7%, aflatoxin G1 was 21.2% and aflatoxin G2 was 23.5%. The detected ranges of aflatoxin B1, B2, G1 and G2 were from 0.1 to $57.2\;{\mu}g/kg$, 0.1 to $42.6\;{\mu}g/kg$, 0.1 to $23.5\;{\mu}g/kg$ and 0.1 to $9.5\;{\mu}g/kg$ respectively. Among total samples, 26 samples contained aflatoxin B1 violated the regulation (less than 10 ug/kg) for aflatoxin B1 of KFDA. From the result, we could presumed that more than a half of samples were contaminated by aflatoxins. Therefore, it seems to be necessary that the new safety giudeline will be established aflatoxin B2, G1 and G2 from herb medicines as aflatoxin B1.
