Abstract

          Several empirical studies of reductions in air pollutants as social distancing and working from home (WFH) policies have sparked recommendations that the COVID-19 pandemic might have been responsible for better air quality particularly in urban area. These findings offer a compelling provocation for the scientific community to detect and investigate variations to air quality as a consequence of government enforced quarantine.

Quantitative ecological risk assessment of inhabitants exposed to polycyclic aromatic hydrocarbons in terrestrial soils of King George Island, Antarctica

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, TM. Hattayanone, O. Pinyakong, V. Viyakarn, S.A. Chavanich, C. Bo, C. Khumsup, I. Kittikoon, P. Hirunyatrakul

 

Abstract

          This study aims to conduct a quantitative ecological risk assessment of human exposure to polycyclic aromatic hydrocarbons (PAHs) in terrestrial soils of King George Island, Antarctica. Generally, the average PAH concentrations detected in King George Terrestrial Soils (KGS) were appreciably lower than those of World Marine Sediments (WMS) and World Terrestrial Soils (WTS), highlighting the fact that Antarctica is one of the most pristine continents in the world.

Parameters Influencing Citizens’ Levels of Satisfaction: Soft Indicators of ‘Good Governance’

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, Thunyanee Pothisarn  & Ketkanda Jaturongkachoke

 

Abstract

          Previous studies highlighted the importance of soft indicators (e.g., quantitative sociological survey) influencing citizen satisfaction towards municipal service quality. Citizen satisfaction assessments have raised concerns over numerous independent parameters such as gender, age, and education on satisfaction levels toward administrative performance.

Using Polycyclic Aromatic Hydrocarbons (PAHs) as a chemical proxy to indicate Tsunami 2004 backwash in Khao Lak coastal area, Thailand

โดย D. Tipmanee, W. Deelaman, ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, K. Schwarzer, and P. Sompongchaiyakul

 

Abstract

          In this study, we attempted to use PAHs as a chemical proxy to trace the transport of land-derived materials caused by the tsunami backwash to better understand how it may have affected the distribution of sedimentary deposition throughout the seabed of Khao Lak coastal areas. By analyzing the compositions of sedimentary PAHs in combination with application of the multivariate descriptive statistical techniques, PAHs were proven to be a promising chemical proxy to indicate the tsunami backwash in the study area.

SEDIMENTARY FEATURES OF TSUNAMI BACKWASH DEPOSITS AS ASSESSED BY MICRO-BEAM SYNCHROTRON X-RAY FLUORESCENCE (μ-SXRF) AT THE SIAM PHOTON LABORATORY

Abstract

          Over the past few years, several attempts have been performed to find alternative “chemical proxies” in order to discriminate “tsunami backwash deposits” from “typical marine sediments”. A wide range of statistical tools has been selected in order to investigate the sediments and/or terrestrial soils transportation mechanism during the tsunami inundation period by using several types of chemical tracers.

Abstract

          This study investigated atmospheric particulate matter (PM) with an aerodynamic diameter of < 2.5 μm (PM2.5) observed at the Prince of Songkla University (Phuket Campus) in southern Thailand. All samples (n = 75) were collected using MiniVol™ portable air samplers from March 2017 to February 2018. Carbonaceous aerosol compositions, i.e., organic carbon (OC) and elemental carbon (EC), water-soluble ionic species (WSIS), and polycyclic aromatic hydrocarbons (PAHs) in the PM2.5 samples were identified and quantified.

Impacts of Biomass Burning in Peninsular Southeast Asia on PM2.5 Concentration and Ozone Formation in Southern China During Springtime—A Case Study

โดย Li Xing, Naifang Bei, Jianping Guo, Qiyuan Wang, Suixin Liu, Yongming Han, ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, and Guohui Li

 

Abstract

          Biomass burning (BB) affects fine particulate matter (PM2.5) concentration and ozone (O3) formation by emitting gaseous precursors and primary aerosols. The Impacts of BB in peninsular Southeast Asia (BB-PSEA) on PM2.5 concentration and O3 formation in southern China are evaluated using a source-oriented WRF-Chem model to simulate an air pollution episode from March 21 to March 25, 2015. The source-oriented model separates the emissions from BB-PSEA

Hospital out-and-in-patients as Functions of Trace Gaseous Species and Other Meteorological Parameters in Chiang-Mai, Thailand

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, Tassanee Paowa

 

Abstract

          The aims of this study were to investigate the impact of meteorological parameters and trace gas concentrations on daily hospital walk-ins and admissions in Chiang-Mai province, Thailand, during 2007–2013. Advanced statistical models, including t-tests, Analysis of Variance (ANOVA), Multiple Linear Regression Analysis (MLRA) and Incremental Lifetime Particulate Matter Exposure (ILPE), were constructed using meteorological data from the Pollution Control Department (PCD), Ministry of Natural Resources and Environment (MNRE), Thailand, and the Thai Meteorological Department at Chiang-Mai Province Air Quality Observatory Site (TMCS) as well as the number of walk-in and admitted patients at Nakornping Hospital, Chiang-Mai (NHCM).

High contribution of secondary brown carbon to aerosol light absorption in the southeastern margin of Tibetan Plateau

โดย Qiyuan Wang, Yongming Han, Jianhuai Ye, Suixin Liu, ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, Ningning Zhang, Yuemei Han, Jie Tian, Cheng Wu, Xin Long, Qian Zhang, Wenyan Zhang, Zhuzi Zhao, Junji Cao

 

Abstract

          The optical properties of atmospheric secondary brown carbon (BrC) aerosol are poorly understood because of its chemical complexity, and this has hampered quantitative assessments of the impacts of this light-absorbing material on glaciers on the Tibetan Plateau (TP). For this study, a statistical approach was developed to investigate BrC light absorption over the southeastern margin of the TP.

Factors affecting stakeholder’s levels of satisfaction with community partnership association in Rayong Province, Thailand

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์

 

Abstract

          Corporate social responsibility (CSR) studies have investigated the differences among five parameters: gender, age, education, income, and occupation; however, the findings are generally dissimilar. For instance, no comprehensive concordance has been reached on the performance and importance of the differences among those five parameters regarding stakeholder expectations and perceptions of CSR activities.
