ABSTRACT
@#This study investigates the mall's Indoor Air Quality (IAQ) to compare changes in levels of Volatile Organic Compounds (VOCs) concentration in the morning and evening. It also explores the sources of emission released that could be related to occupants' health status (dizziness, headaches, flu, running nose, nose stuffy, nose irritation, eye irritation, watery eye, and eye reddening). A questionnaire survey approach was used to collect quantitative data involving 32 workers from malls in Malacca, Malaysia. This study established models to measure changes in VOCs level in two different sessions for a given area. Also, predictors related to the work context (human performance and condition) were found to be significantly related to occupants' symptoms. Two significant values identified the changes in VOCs concentration for morning and evening sessions in the lobby, bakery, eye ware shop, mobile centers, and supermarket. No evidence supports the exposure towards the personal individual in the present findings. This study contributes to the literature on levels of VOCs in the shopping mall as well as the emission sources. It also suggests that more comprehensive monitoring can be achieved, particularly in the context of Malaysia.

ABSTRACT
Objective To investigate the dosimetry and feasibility of target volume reduction in three-dimensional conformal radiotherapy for non-small cell lung cancer(NSCLC).Methods Two differ-ent radiation treatment planning,the conventional conformal planning and the small volume conformal plan-ning,were designed for 32 NSCLC patients.Dose-olume histograms were used to assess the dosimetric dis-parity in target regions and surrounding organs at risk.Results Small volume conformal planning could meet the demand of target dose.The least dose,the maximum dose,and the mean dose at subclinical targets were 50.93 Gy,54.60 Gy and(52.37 ±1.02)Gy,respectively.Comparing with the conventional conformal planning,small volume conformal planning reduced the mean dose of lung,spinal cord and esophagus(P<0.05).Conclusion Small volume conformal planning can meet the dosimetric requirement of target vol-ume for NSCLC and reduce the dose of normal tissues,which is worthy of further clinical study.
ABSTRACT
Este artigo apresenta uma visão crítica acerca da mudança dos camelôs para os denominados shoppings populares, implementados pela Prefeitura Municipal de Belo Horizonte, com a finalidade de cumprir o código de conduta do projeto "Centro Vivo". Argumenta-se que a atitude da prefeitura foi de limpeza da cidade, provocando uma desarticulação do trabalho informal dos camelôs e "toreros", bem como aumentando a precariedade de suas condições políticas e sociais de trabalho. O argumento baseia-se no discurso da mídia impressa e de algumas atas de reunião da prefeitura concernentes ao tema. Os autores contrastam o discurso com o dos próprios camelôs, que foram entrevistados, a respeito de como percebiam o processo de mudança para os shoppings e o que isso acarretou em termos do seu trabalho.

Purchasing professionals utilize a e-commerce to sell or buy better products with good price. The marketers of agricultural products recognized that e-commerce has made significant inroads, and the Internet is fast becoming an essential tool for purchasing. The purpose of this research was to assess the realities of internet shopping malls of agricultural products including the actual condition of the sites, payment methods, order methods, membership and shipping methods. The results show that operating internet shopping mall of agricultural products are operated poorly in terms of buyer-seller relationship, payment and distribution. The results also provide some practical implication for marketers regarding the establishment of database, improvement of distribution and internet shopping mall operation, and importance of education on e-business for agricultural markets.
