    In this paper, optimum routing was developed based on the travel salesman method and integrated in ArcInfo GIS using linear programming. The results of the optimized travel distances and times for residential waste collection and routing to disposal site were used to calculate the number and type of required track collection, labour requirement, costing of waste collection and to determine the overall solid waste management efficiency through waste management operation research methods. The objective of the study was to optimize residential collection and hauling to disposal site through operation cost minimization for Petaling Jaya Municipality in the state of Selangor, Malaysia. The study determined that with optimized routes and recycling possibilities, the total cost of waste collections could be reduced from RM90,372 to RM20,967, with a reduction of 76.8%. It was also revealed that optimum routes might not necessarily be the shortest distance from point A to point B as travel time maybe high on short distances due to traffic congestion and the presence of many traffic lights. Techniques and methods developed using general GIS have proven effective in route optimization and allowed management of data to suit local conditions and limitations of waste management for the studied area. Thus, scenarios of travel distances, time and waste quantity value generated from the GIS enabled appropriate determination of the number of waste trucks and labour requirements for the operation and the overall calculation of costs of waste management based on the operation research methods used in the study.

    At present, research in composite materials is being directed at using natural fibres instead of synthetic fibres. Kenaf which is extensively grown in the Far East including Malaysia, has been identified as a bast (stem) fibre with significant market potential. In this work, long and random kenaf fibres (non-woven mat form) were used in the as-received condition and alkalized with a 0.06M NaOH solution. They were combined with polypropylene thin sheets, sandwiched between layers of kenaf fibres and hot-pressed to form natural fibre composites. The mechanical properties of the composites were investigated to observe the effect of fibre alignment, fibre treatment and pre-irradiation method used. A general trend was observed whereby alkalized and long fibre composites gave higher flexural modulus and flexural strength compared with random mat and untreated fibres. The long fibre composites also gave a higher work of fracture. However, the correlation between fibre surface treatment and the work of fracture was less clear. Pre-irradiation on the polypropylene pellets and fibres before the composite is manufactured showed significant improvement on the flexural modulus and flexural strength. The bond performance test performed on the treated composites demonstrated good bonding and interfacial adhesion between the fibre and matrix. However, the method of moulding used need to be improved to optimize the performance of the composites.

    One of the prime inspirations for this work emerge from the need to deal with our
    common assets (the Land). To build up a formal approach that can be utilized to
    address the issues emerges from a mind boggling circumstance in land
    administration. The capacity to track the progressions as it is connected to land
    everywhere throughout the year. A considerable lot of the land exchanges are as yet
    in light of 2D ideal models that have frustrated fast advancement in thickly urban
    condition. The consideration of 3D enhanced the functionalities of different models.
    Be that as it may, the dynamic idea of the land has an imperative part in the
    advancement of the land administration framework. One of the significant reason the
    expansion in intricacy in land utilize required that Land Administration Domain Model
    (LADM) concept in land administration has an enhanced limit is to deal with the
    current 2D and 3D. The need to talk about time dimension emerges from the way
    that individuals relationship to the land has an exceptionally powerful nature, all the
    LADM packages has time (Temporal) components. LADM completely bolster forming
    (historical information) as all classes inherit from VersionObject, and all LA_RRR
    object have the quality TimeSpace. 2D/3D space and time incorporation is not
    profoundly integrated into a 3D/4D spatiotemporal portrayal. The preparatory test
    case in this study affirmed the conceivable outcomes of having a move or
    development (with time) of characteristic limits from their underlying positions. Thus,
    the dynamic idea of the land in connection to man, the benefits of this model to the
    land proprietors, land merchants, and the administration can't be over stressed. This
    study tries to clarify the current 2D/3D approach and broke down preparatory
    requirements for 4D with a specific end goal to see the estimation of the approach.
    The primary future research exertion focuses on melding on the most proficient
    method to coordinate the model completely into Country profile in the study area.

    The Climatic performance of courtyard residential buildings needs to be
    investigated if the assertion that courtyard is a microclimate modifier is to be
    accepted. Therefore, this study seeks to examine the microclimatic performance
    of two existing courtyard residential buildings with similar characteristics in
    Kafanchan-Kaduna Nigeria, -the fully enclosed courtyard residential building and
    the semi-enclosed courtyard residential building. The purpose of this research is
    to investigate their microclimatic performances in other to establish the best
    courtyard house. This study uses measurement to achieve its aim. The tool
    employed for data collection is the Hobo Weather Data Loggers (HWDL). Three
    HWDL were used to collect data in the two case-study, and the third one was
    placed in the outside area as a benchmark. Only air temperature and relative
    humidity were measured. This study revealed a tangible difference in the
    microclimatic performance of the two case-study. The fully enclosed courtyard
    residential building is seen to have air temperature difference of 1 oC to 3 oC, and
    the relative humidity difference of 4 % to 8 %. In conclusion, the fully enclosed
    courtyard house demonstrated a more favorable microclimatic performance than
    the semi-enclosed, and further simulation studies towards its optimization are
    required.

    Extraction of gelatin using traditional acid-base pretreatment method has several limitations
    such as time consuming and causes serious water pollution. Chemical treatment often being used
    as an alternative process to overcome the weaknesses of the conventional method. However,
    excessive chemical elements would damage the structure of the gelatin due to its high sensitivity
    to the acid content. High Pressure Processing (HPP) is a novel and environmental friendly
    method that has been suggested to assist gelatin extraction. Pressurization during pretreatment
    could reduce the extraction time and amount of acid used. It also has a potential in enhancing the
    properties of the gelatin extract and increasing the gelatin yield. In this research, One-Factor-
    at-Time (OFAT) and optimization study were done to determine the optimum parameters for
    extraction of gelatin assisted by HPP from red tilapia skin. Four parameters; applied pressure,
    pressure holding time, ratio of acid to skin and extraction time have been selected for the OFAT
    design and concentration of the gelatin extract and percentage of yield gelatin were evaluated.
    From OFAT, optimum technical parameters for response surface optimization design were 250
    MPa pressure, 7.5 ml of acid to 1 g of skin and 12 hours extraction time. Pressure holding
    time was fixed for 10 min. FCCCD has been used for optimization study. Results from the
    data shows that the optimum conditions for gelatin extraction from red tilapia skin were 250
    MPa for pressure, 10 min of pressure holding time, 7.5 ml of acid for 1 g of skin and 12 hours
    of extraction time while the maximum concentration and yield were 19.51 mg/ml and 32.04%
    (320.4 mg/g), respectively. These findings proved that HPP could increase the concentration
    and the yield of the gelatin while reducing the chemical waste and shortening the extraction
    process.

    BACKGROUND: The interpretive paradigm and hermeneutic phenomenological design are the most popular methods used in international cross-cultural research in healthcare, nurse education and nursing practice. Their inherent appeal is that they help researchers to explore experiences. The ethnographic principle of cultural interpretation can also be used to provide meaning, clarity and insight.

    AIM: To examine the use of hermeneutic phenomenology and the ethnographic principle of cultural interpretation in a research study conducted with Malaysian nurses on part-time, transnational, post-registration, top-up nursing degree programmes provided by one Australian and two UK universities.

    DISCUSSION: To enable the researcher to undertake international cross-cultural research and illuminate Malaysian nurses' views for the reader, cultural aspects need to be considered, as they will influence the information participants provide. Useful strategies that western researchers can adopt to co-create research texts with interviewees are outlined. The paradigm and research designs used in the study revealed the views and experiences of Malaysian nurses.

    CONCLUSION: Hermeneutic phenomenology enabled the exploration of participants' experiences, and the ethnographic principle of cultural interpretation enabled the researcher's reflexivity to provide emic and etic views for the reader.

    IMPLICATIONS FOR PRACTICE: This paper adds to the discussion of the paradigms and research designs used for international, cross-cultural research in Asia. It identifies the influence participants' cultural values have on their confidence and level of disclosure with western researchers.

    Swiftlet
    s
    are small insectivorous birds which breed throughout Southeast Asia and
    the South Pacific.
    Among many swiftle
    t species, only a few are notable to produce edible bird’s
    nest
    s
    (EBN) from the secreted saliva during breeding seasons.
    The taxonomy of swiftlet
    s
    remains one of the most controversial in the avian species due to the high similarity in
    morphological charac
    teristics among the species. Over the last few decades, researchers have
    studied the taxonomy of swiftlet
    s
    based on the morphological
    trade
    , behavior, and genetic
    traits
    .
    However, despite all the efforts,
    the
    swiftlet taxonomy remains unsolved.
    The
    EBN is one of
    the
    most expensive animal products
    and frequently being referred
    to
    as the “
    Caviar of the East
    ”.
    The
    EBN market value varies from
    US
    $1000.00 to
    US
    $10,000.00 per kilogram depend
    ing
    on
    its grade, shape, type and origin.
    Hence, bird’s nest harve
    sting is considered a lucrative industry
    in many countries in Southeast Asia.
    However,
    the
    industry faced several challenges over the
    decades such as the authenticity of the EBN, the quality assurance and the depletion of swiftlet
    population. Furthermore,
    there is limited scientific evidence regarding EBN’s medical benefits
    as
    claimed by manufacturers. This paper reviews the taxonomy of swiftlet
    s
    , its morphological
    characteristics, the challenges currently encountered by the industry, and finally the
    compos
    ition and medical benefits of EBN.

    It is hard to identify the local Malay identity in a design context compared to other cultural oriented design in several countries. This paper tries to uncover how designers interpret local identity embodied agent based on local items influences and understood and the influence of incremental, radical design that changes respective to preceding designs. A descriptive study through the literature reviews focusses on a type of artefact initiated through cultural-oriented design. Based on the preliminary study, a sampling taken from the Chinese, Indian, Japanese or European consistently apply the same fundamental understanding in regards to the culture-oriented design. From the same point of view, teapot seems to be used as one of the dominant artefact indicating the design preferences. This research will benefit both the academia and the industry and identify significant identity based on the local context and become an embodied agent to give impact in establishing the state-of-the-art of brand, the identity of local design, establish new trademark towards generating domestic, international economy and promote the nation worldwide throughout design platform.

    The issue of classifying objects into groups when measured variables in an experiment are mixed has attracted the attention of statisticians. The Smoothed Location Model (SLM) appears to be a popular classification method to handle data containing both continuous and binary variables simultaneously. However, SLM is infeasible for a large number of binary variables due to the occurrence of numerous empty cells. Therefore, this study aims to construct new SLMs by integrating SLM with two variable extraction techniques, Principal Component Analysis (PCA) and two types of Multiple Correspondence Analysis (MCA) in order to reduce the large number of mixed variables, primarily the binary ones. The performance of the newly constructed models, namely the SLM+PCA+Indicator MCA and SLM+PCA+Burt MCA are examined based on misclassification rate. Results from simulation studies for a sample size of n=60 show that the SLM+PCA+Indicator MCA model provides perfect classification when the sizes of binary variables (b) are 5 and 10. For b=20, the SLM+PCA+Indicator MCA model produces misclassification rates of 0.3833, 0.6667 and 0.3221 for n=60, n=120 and n=180, respectively. Meanwhile, the SLM+PCA+Burt MCA model provides a perfect classification when the sizes of the binary variables are 5, 10, 15 and 20 and yields a small misclassification rate as 0.0167 when b=25. Investigations into real dataset demonstrate that both of the newly constructed models yield low misclassification rates with 0.3066 and 0.2336 respectively, in which the SLM+PCA+Burt MCA model performed the best among all the classification methods compared. The findings reveal that the two new models of SLM integrated with two variable extraction techniques can be good alternative methods for classification purposes in handling mixed variable problems, mainly when dealing with large binary variables.

    BACKGROUND: Conversational interfaces (CIs) in different modalities have been developed for health purposes, such as health behavioral intervention, patient self-management, and clinical decision support. Despite growing research evidence supporting CIs' potential, CI-related research is still in its infancy. There is a lack of systematic investigation that goes beyond publication review and presents the state of the art from perspectives of funding agencies, academia, and industry by incorporating CI-related public funding and patent activities.

    OBJECTIVE: This study aimed to use data systematically extracted from multiple sources (ie, grant, publication, and patent databases) to investigate the development, research, and fund application of health-related CIs and associated stakeholders (ie, countries, organizations, and collaborators).

    METHODS: A multifaceted search query was executed to retrieve records from 9 databases. Bibliometric analysis, social network analysis, and term co-occurrence analysis were conducted on the screened records.

    RESULTS: This review included 42 funded projects, 428 research publications, and 162 patents. The total dollar amount of grants awarded was US $30,297,932, of which US $13,513,473 was awarded by US funding agencies and US $16,784,459 was funded by the Europe Commission. The top 3 funding agencies in the United States were the National Science Foundation, National Institutes of Health, and Agency for Healthcare Research and Quality. Boston Medical Center was awarded the largest combined grant size (US $2,246,437) for 4 projects. The authors of the publications were from 58 countries and 566 organizations; the top 3 most productive organizations were Northeastern University (United States), Universiti Teknologi MARA (Malaysia), and the French National Center for Scientific Research (CNRS; France). US researchers produced 114 publications. Although 82.0% (464/566) of the organizations engaged in interorganizational collaboration, 2 organizational research-collaboration clusters were observed with Northeastern University and CNRS as the central nodes. About 112 organizations from the United States and China filed 87.7% patents. IBM filed most patents (N=17). Only 5 patents were co-owned by different organizations, and there was no across-country collaboration on patenting activity. The terms patient, child, elderly, and robot were frequently discussed in the 3 record types. The terms related to mental and chronic issues were discussed mainly in grants and publications. The terms regarding multimodal interactions were widely mentioned as users' communication modes with CIs in the identified records.

    CONCLUSIONS: Our findings provided an overview of the countries, organizations, and topic terms in funded projects, as well as the authorship, collaboration, content, and related information of research publications and patents. There is a lack of broad cross-sector partnerships among grant agencies, academia, and industry, particularly in the United States. Our results suggest a need to improve collaboration among public and private sectors and health care organizations in research and patent activities.

    BACKGROUND/AIMS: The impact of a scientific article in its respective field is reflected by its citation count. The purpose of this review was to conduct a citation analysis in order to identify and analyze the top 50 most cited articles published in Dental Traumatology since its inception in order to highlight the contribution of the journal to the field of Dental Traumatology.

    METHODS: Elsevier's Scopus was used to search and analyze the 50 most frequently cited scientific papers. After the screening process, two reviewers arranged the articles in a descending order based on their citation counts. Each article was then cross-matched with Google Scholar. The articles were analyzed, and information including citation counts, citation density, publication year, authorship, contributing institutions and countries, article topic, study design, and keywords was extracted.

    RESULTS: The literature search identified 2421 articles. The citation counts of the 50 selected articles varied from 117 to 580 (Scopus) and 206 to 1130 (Google Scholar). The year in which most top 50 articles were published was 2002 (n = 5). Among 105 authors, the greatest contribution was made by JO Andreasen (n = 12). Most of the articles originated from the United States (n = 12) with the greatest contributions from the University Hospital (Rigshospitalet), Copenhagen, Denmark (n = 6). Original research article was the most frequent study design (n = 34). The majority of the top 50 articles were focused on traumatic dental injuries. Among 131 unique key words, root resorption (n = 6) was the most frequently used. A non-significant correlation occurred between citation count (correlation coefficient = 0.127, P = .378), citation density (correlation coefficient = 0.654, P = 2.493), and publication age.

    CONCLUSIONS: This study identified the top 50 most cited articles published in this journal in the specialty of Dental Traumatology. The publication year of an article was not significantly associated with citation count nor citation density.

    This qualitative study reviewed the concept of Mat Rempit. This study used two methods of interviews. Firstly, individual interviews were conducted with 16 individuals who were from a school in Semenyih, Selangor and they had been involved in rempit activities. Secondly,focus group interviews were conducted involving three groups of individuals who were charged under Section 42 for driving recklessly their motorcycles in Penang, Johor Baharu and Kuala Lumpur. The main results of interviews indicate that rempit can be defined as any activity involving a motorcycle racing team of at least two people Generally, the race comprised various actions such as doing a sprint, or a lap and also stunts (such as, a wheelie or wheekang). In addition, there is ramping of engines of molorcycles and creating excessively loud sounds as well as shouting and showing hand signals. A Mat Rempit is a person involved in these activities. Other related findings and implications are also discussed.
