Purpose: The study attempts to explore the operational performance of the existing Malaysian logistics companies and the extent of their adoption of digitalization. The role of digitalization in enhancing the performance of companies in the logistics industry in Malaysia, for value creation, is the topic of study. Research design, data and methodology: A qualitative research method with a semi-structured interview approach was applied and judgmental sampling was used as the sampling technique to collect data. The research has chosen nine companies in the logistics industry in Peninsular Malaysia, with the interviews aimed at eleven members of top and middle-level management. Data analysis was performed using logical system techniques to examine and evaluate data, reorganizing feedback, comparing it with literature, and transforming it into structured, valuable information after interviews. Results: The study revealed mixed opinions on digitalization in logistics, despite its potential benefits such as improved operational efficiency, real-time information, and customer service. However, high costs may hinder financial performance and require revisions due to stakeholder involvement. Conclusions: The Malaysian logistics industry's adoption of digitalization is gaining traction, with most companies satisfied with their status. However, challenges like cost and inefficiency persist, prompting calls for government support to improve efficiency and reduce costs while ensuring sustainable transportation.

This paper presents seasonal variation of $PM_{10}$ over five urban sites in Sabah, Malaysia for the period of January through December 2012. The variability of $PM_{10}$ along with the diurnal and weekly cycles of CO, $NO_2$, $SO_2$, and $O_3$ at Kota Kinabalu site were also discussed to investigate the possible sources for increased $PM_{10}$ concentration at the site. This work is crucial to understand the behaviour and possible sources of $PM_{10}$ in the urban atmosphere of Sabah region. In Malaysia, many air pollution studies in the past focused in west Peninsular, but very few local studies were dedicated for Sabah region. This work aims to fill the gap by presenting the descriptive statistics on the variability of $PM_{10}$ concentration in the urban atmosphere of Sabah. To further examine its diurnal and weekly cycle pattern, its responses towards the variations of CO, $NO_2$, $SO_2$, and ozone were also investigated. The highest mean value of $PM_{10}$ for the whole study period is seen from Tawau ($35.7{\pm}17.8{\mu}g\;m^{-3}$), while the lowest is from Keningau ($31.9{\pm}18.6{\mu}g\;m^{-3}$). The concentrations of $PM_{10}$ in all cities exhibited seasonal variations with the peak values occurred during the south-west monsoons. The $PM_{10}$ data consistently exhibited strong correlations with traffic related gaseous pollutants ($NO_2$, and CO), except for $SO_2$ and $O_3$. The analysis of diurnal cycles of $PM_{10}$ levels indicated that two peaks were associated during the morning and evening rush hours. The bimodal distribution of $PM_{10}$, CO, and $NO_2$ in the front and at the back of ozone peak is a representation of urban air pollution pattern. In the weekly cycle, higher $PM_{10}$, CO, and $NO_2$ concentrations were observed during the weekday when compared to weekend. The characteristics of $NO_2$ concentration rationed to CO and $SO_2$ suggests that mobile sources is the dominant factor for the air pollution in Kota Kinabalu; particularly during weekdays.

The concern for the global environment ensues researchers from various disciplines to work in collaboration to tackle with the issues of sustainability and environmental conservation for well-being of the people. In this study, we have selected and focused on few basic environment-effecting factors such as temperature, humidity, carbon dioxide and oxygen concentration level and referred them as meteorological data. In this paper, we present the development of our own customized hardware setup, environmental monitoring device (EMD) to obtain the data. Utilizing the relationship among these basic parameters, represented in the form of formulas and equations, we tried to encode them using Matlab programming. Data visualization is achieved by plotting the graphs of basic parameters obtained from EMD as well for the derivatives using Matlab programs.

Background: Head and neck cancer (HNC) is the eighth most common cancer as estimated from worldwide data. The incidence of HNC in Peninsular Malaysia was reported as 8.5 per 100,000 population. This study was aimed to determine the treatment outcomes for HNC patients treated in the Oncology Unit of University Malaya Medical Centre (UMMC). Materials and Methods: All newly diagnosed patients with squamous cell carcinoma of head and neck (HNSCC) referred for treatment to the Oncology Unit at UMMC from 2003-2010 were retrospectively analyzed. Treatment outcomes were 5-year overall survival (OS), cause specific survival (CSS), loco-regional control (LRC) and radiotherapy (RT) related side effects. Kaplan-Meier and log rank analyses were used to determine survival outcomes, stratified according to American Joint Committee on Cancer (AJCC) stage. Results: A total of 130 cases were analysed. Most cases (81.5%) were at late stage (AJCC III-IVB) at presentation. The 5-year OS for the whole study population was 34.4% with a median follow up of 24 months. The 5-year OS according to AJCC stage was 100%, 48.2%, 41.4% and 22.0% for stage I, II, III and IVA-B, respectively. The 5-year overall CSS and LCR were 45.4% and 55.4%, respectively. Late effects of RT were documented in 41.4% of patients. The most common late effect was xerostomia. Conclusions: The treatment outcome of HNSCC at our centre is lagging behind those of developed nations. Efforts to increase the number of patients presenting in earlier stages, increase in the use of combined modality treatment, especially concurrent chemoradiotherapy and implementation of intensity modulated radiotherapy, may lead to better outcomes for our HNC patients.

Objectives : The purpose of this study is correct the scientific name of Aquilariae Lignum in Korean Herbal Pharmacoepia. Methods : The production areas of Aquilariae Lignum and its trading status with China in Chinese history, Sanscrit-Chinese Translation Sutra, Naming year and the discovered district in main Aquilaria spp., Several nation's Pharmacoepia, The Plant List(TPL), Convention on International Trade in Endangered Species of Wild fauna and flora(CITES) and The International Union for Conservation of Nature(IUCN) were cross-checked. Results : The records in the Jiaozhouyiwuzhi written in the early 2nd century said that Aquilariae Lignum was produced in Vietnam. NanfangCaomuZhuang written in 304 said that Agarwood in Vietnam had white flowers. Vietnam had led production and trading of Aquilariae Lignum until Qing Dynasty. Aquilariae Lignum from Malaysia and Indonesia was not traded with China. In Sanscrit-Chinese Translation Sutra, India Aquilariae Lignum was translated as Vietnam Aquilariae Lignum. Aquilaria malaccensis was discovered from Malay-Peninsular in 1783, and has green or dirty yellow flowers. A. agallocha from North-Eastern India in 1814, white flowers. A. crasssna from Vietnam in 1914, white flowers. A. crassna is different from A. malaccensis in several ways, such as flower, fruit, seed and disribution. In several Nation's Pharmacoepia, A. crassna was a synonym of A. agallocha. But in TPL, CITES and IUCN, A. malaccensis was an accepted name, and A. agallocha was a synonym of A. malaccensis. Conclusions : These results show that the original species of Aquilariae Lignum in Korea Herbal Pharmacoepia should be reversed from A. agallocha to A. crassna Pierre ex Lacomte.
