โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, Akihiro Iijima

 

Abstract

          Estimating the atmospheric concentrations of PM10-bounded selected metals in urban air is crucial for evaluating adverse health impacts. In the current study, a combination of measurements and multivariate statistical tools was used to investigate the influence of anthropogenic activities on variations in the contents of 18 metals (i.e., Al, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd, Sb, Ba, La, Ce and Pb) in ambient air. The concentrations ofPM10-bounded metals were measured simultaneously at eight air quality observatory sites during a half-year period at heavily trafficked roads and in urban residential zones in Bangkok, Thailand.

Assessing human exposure to PM10-bound polycyclic aromatic hydrocarbons during fireworks displays

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, Mattanawadee Hattayanone, Oramas Suttinun, Chukkapong Khumsup, Itthipon Kittikoon, Phoosak Hirunyatrakul, Junji Cao

 

Abstract

          The “Loy Krathong” festival is a major annual Thai event that includes firework displays. It takes place on the evening of the full moon in the 12th month of the traditional Thai lunar calendar. Since fireworks are widely considered a major source of PAHs, it is considered reasonable to expect a significant increase in PAH levels during this event. The overall PAH profile at the six air quality observatories operated by the Pollution Control Department (PCD), Ministry of Natural Resources and Environment (MNRE), showed that the Kingdom of Thailand's atmosphere was dominated by 5e6-ring PAHs during the firework display period.

Application of Binary Diagnostic Ratios of Polycyclic Aromatic Hydrocarbons for Identification of Tsunami 2004 Backwash Sediments in Khao Lak, Thailand

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์

 

          Identification of Tsunami deposits has long been a controversial issue among geologists. Although there are many identification criteria based on the sedimentary characteristics of unequivocal Tsunami deposits, the concept still remains ambiguous. Apart from relying on some conventional geological, sedimentological, and geoscientific records, geologists need some alternative “proxies” to identify the existence of Tsunami backwash in core sediments.

Abstract

          Levoglucosan, as a biomass tracer, and sixteen polycyclic aromatic hydrocarbons (PAHs) in PM2.5 ambient air samples collected from Tak Province during smoke and non-smoke episodes were analyzed. The average PM2.5, levoglucosan and total PAHs concentrations in the smoke episode were 61.64 ± 22.85, 1.00 ± 0.41 μg/m3 and 6.32 ± 2.26 ng/m3, respectively. This figures were significantly higher than those recorded during the non-episode (13.76 ± 5.58, 0.12 ± 0.03 μg/m3 and 2.59 ± 0.15 ng/m3, respectively).

A preliminary study of using polycyclic aromatic hydrocarbons as chemical tracers for traceability in soybean products

โดย ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์

 

Abstract

          Polycyclic Aromatic Hydrocarbons (PAHs) are a class of very stable organic molecules made up of only carbon and hydrogen and contain two to eight fused aromatic rings. PAHs are formed during incomplete combustion of organic materials such as fossil fuels, coke and wood. PAHs can be found in environment, the atmosphere, surface water, sediment, soil, food and in lipid tissues of both aquatic and terrestrial organisms.

The Schooling Gap between the Deep South and the Rest of the South in Thailand

โดย Md. Nasir Uddin และ ผศ.ดร. ศรัณย์ ศานติศาสน์* (อาจารย์ประจำคณะพัฒนาการเศรษฐกิจ สถาบันบัณฑิตพัฒนบริหารศาสตร์)

 

ABSTRACT

          This paper aims to compare the educational attainment of a conflict region (the Deep South) and a non-conflict region (the rest of the South) of Thailand using the Socio-Economic Survey, 2015. This paper employs the Instrumental Variable approach and Oaxaca-Blinder decomposition in an intergenerational regression model. When controlling parental schooling, household income and size, religion, and gender, the results show that children from the Deep

Spatial distribution, sources and quantitative human health risk assessments of polycyclic aromatic hydrocarbons in urban and suburban soils of Chile

โดย Ronbanchob Apiratikul, ศ.ดร.ศิวัช พงษ์เพียจันทร์* อาจารย์ประจำคณะพัฒนาสังคมและยุทธศาสตร์การบริหาร สถาบันบัณฑิตพัฒนบริหารศาสตร์, Woranuch Deelaman

 

Abstract

          This work investigated the concentrations and health risks of polycyclic aromatic hydrocarbons (PAHs) found in Chilean soils for the first time. The urban and suburban soils were collected from 28 sampling sites in three regions of Chile: Magallanes (in Punta Arenas commune), Valparaı´so and the Santiago metropolitan area. The PAH concentrations, fractions and their potential sources were studied.

Does Marriage Discourage Female Labor Force Participation? Empirical Evidence from Thailand

โดย Tumsarp, P., ศ.ดร.พิริยะ ผลพิรุฬห์* อาจารย์ประจำคณะพัฒนาการเศรษฐกิจ สถาบันบัณฑิตพัฒนบริหารศาสตร์

 

Abstract

          In labor supply theory, marriage can be one of the obstacles making it less likely for a woman to participate in the labor market. However, the relationship between marriage and a female’s working outside the home can vary according to a country’s stage of economic development. This paper therefore aims to investigate the impact of marital status on labor force participation of women in developing countries by using Thailand as a case study.

ABSTRACT

          This study employed chemical characterisation to determine the source of polycyclic aromatic hydrocarbons (PAHs) in the terrestrial soils of King George Island, Antarctica. The total concentrations of 12 PAHs in the samples of terrestrial soils collected at 44 sites ranged from 1.83 to 32.9 ng g-1 with an average value of 10.8 ± 8.22 ng g-1. The concentrations of these PAHs were relatively lower compared with those found in other studies in other locations.

Participating in religious activities and adolescents’ self-esteem: empirical evidence from buddhist adolescents in Thailand

โดย Phaphon Plumwongrot & ศ.ดร.พิริยะ ผลพิรุฬห์* อาจารย์ประจำคณะพัฒนาการเศรษฐกิจ สถาบันบัณฑิตพัฒนบริหารศาสตร์

 

          This paper aims at quantifying the relationship between participating in Buddhist religious activities and Buddhist adolescents’ self-esteem. It uses Thailand as a case study as Buddhism is the predominant religion of this country. Using ordered-probit regression models with a national survey of 1,648 Thai Buddhist adolescents, our results show that participating in Buddhist religious activities that involved maintaining mindfulness, including prayer and meditation, is found to have a statistically positive relationship with higher self-esteem among Buddhist adolescents in Thailand.
