Indonesia and Nepal, which are in the World Health Organization South-East Asia Region, are the countries with the highest numbers of confirmed cases and deaths since the start of the COVID-19 pandemic outside of the Region of the Americas and the European Region. Since its first confirmed case on March 2nd, Indonesia has reported 100,303 cases and 4,838 deaths as of July 28, 2020, which is the highest number of cases in Southeast Asia. As restrictions in response to the pandemic continue, the public’s psychological anxiety is gradually increasing. There were 889 undergraduates and graduate students living in Indonesia or Nepal (Indonesia: 551 persons; Nepal: 338 persons). An English questionnaire was administered to participants through an online survey using Google survey. Regarding the factors affecting anxiety, they were “trust in hospitals for COVID-19 diagnosis,” “possibility of contracting COVID-19,” “concerns about family members getting COVID-19,” “national discrimination due to COVID-19,” “chronic disease status,” “experience of purchasing masks,” and “health behaviors” in Indonesia, and “trust in hospitals for COVID-19 diagnosis,” “risk of the family getting infected by COVID-19,” and “depression score” in Nepal. In both countries, significant effects of “trust in hospitals for COVID-19 diagnosis” and “risk of the family getting infected by COVID-19” were observed. Therefore, educational institutes should implement touch-free educational programs to develop social activities and prevent psychological and psychiatric issues due to the COVID-19. Other educational institutions and authorities should consider this result to develop further programs and projects.

By using numerical simulation, vast and detailed information and observation of the physics of flow over a train model can be obtained. However, the accuracy of the numerical results is questionable as it is affected by grid convergence error. This paper describes a systematic method of computational grid refinement for the Unsteady Reynolds Navier-Stokes (URANS) of flow around a generic model of trains using the OpenFOAM software. The sensitivity of the computed flow field on different mesh resolutions is investigated in this paper. This involves solutions on three different grid refinements, namely fine, medium, and coarse grids to investigate the effect of grid dependency. The level of grid independence is evaluated using a form of Richardson extrapolation and Grid Convergence Index (GCI). This is done by comparing the GCI results of various parameters between different levels of mesh resolutions. In this study, monotonic convergence criteria were achieved, indicating that the grid convergence error was progressively reduced. The fine grid resolution’s GCI value was less than 1%. The results from a simulation of the finest grid resolution, which includes pressure coefficient, drag coefficient and flow visualization, are presented and compared to previous available data.

Sarimah Ismail,Muhammad Sukri Saud,Nor Fadila Mohd Amin,Mohd. Rizal Mohd Said 세계문화관광학회 2007 Conference Proceedings Vol.8 No.0

The early 1970s saw the emergence of customer satisfaction as a legitimate field of inquiry and the volume of consumer satisfaction research has increased significantly during the last four decades. With regard to the food service industry, most restaurateurs have realised the effect of customer satisfaction on customer loyalty for long-term business survival, and have chosen to improve customer satisfaction in an attempt to achieve business goals. However, the development of a model that helps restaurateurs to understand what customers need in terms of a satisfactory experience and how those determinants can be better managed to improve satisfaction has not yet received enough attention. Therefore, this qualitative study that applied grounded theory research approach and case study research strategy has conducted in three Malaysian Malay restaurants to develop a conceptual model of customer satisfaction based on customers' experience, and not the manager's, to help managerial staff to understand the whole process of customer satisfaction in a restaurant. Data were collected adopting in-depth semi-structured interviews, participant observation, direct observation and documentary evidence. The data was analyzed using NUDIST computer software. Finding of this study views that dining experience as a service and product production process that consist of three major concepts: Input, transformation and output of the dining experience. The input of the dining experience (contains of the determinants and management of customer satisfaction), transformation of the dining experience (involves seven stages that starts from the customers' getting information about the restaurants then experiencing the dining themselves) and the output of the dining experience process (is expressed through psychological impact of pleasurable feelings that then motivate the customers to show behavioural changes: revisit the restaurant, repurchase restaurant's products and/or service, price tolerance, first choice, conveying positive word-of-mouth recommendations and showing preference. These were viewed as indicators of service loyalty).

EFFECT OF AGRICULTURAL BY-PRODUCT DIETS ON CARCASS CHARACTERISTICS OF FOUR TYPES OF CATTLE IN THE FEEDLOT

Dahlan, I.,Rahman-Haron, A.,Sukri, M.H.I. Asian Australasian Association of Animal Productio 1992 Animal Bioscience Vol.5 No.3

Five type of formulated diet from agricultural by-products (ABP) were fed to four breedtype of cattle in feedlot. The ABP used are palm kernel cake (PKC), palm press fibre (PPF), palm oil mill effluent (POME), cocoa pod (COP), coffee pulp (COF) and pineapple waste (PAP). The formulated diets are PS (52% PKC, 15% PPF and 30% POME), PF (57% PKC, 20% PPF and 20% POME), PA (2% PKC and 55% PAP), CO (42% PKC and 55% COP) and CF (67% PKC and 30% COF) with 1% urea, 1% NaCl and 1% vitamins premix. The cattle breedtypes are Kedah-Kelantan (KK), Brahman-KK (BK), Hereford-KK (HK) and Sahiwal-Friesian (SF). The result showed that breedtype significantly affect all the carcass characteristic except dressing percentage. Each breedtype has it's specific carcass characteristics. HK cattle gave high marbling, BK has high % of carcass bone, KK has high % of carcass meat and low % of carcass fat (lean meat type) and SF has high % of carcass fat. Diet-type significantly affect the deposition of fat in the carcass. High moisture diets (PA and CO) produced significantly higher % carcass bone, the lowest % carcass fat and the highest % carcass meat (65.3%). PF, CF, PA and CO diets produced 63.4%, 59.9%, 55.3% and 54.1% carcass meat respectively.

Heat treatment of wood is an attractive alternative environmentally-friendly treatment to add value of less valuable woods by improving color, dimensional stability, and natural durability. To improve the color properties of Korean white pine (Pinus koraiensis) and royal paulownia (Pauwlonia tomentosa), we treated the woods at 160℃, 180℃, 200℃, and 220℃ for 2 hours. Color change after heat treatment was evaluated using the CIE-Lab color system and survey was conducted to determine the consumer preferences towards color of heat-treated wood. Lightness (L*) decreased with increasing temperature and the higher degree of change was obtained in royal paulownia. The red/green chromaticity (a*) in both wood decreased after heat treatment at 160℃, and constantly increased after heat treatment at 180℃ to 220℃. Yellow/blue chromaticity (b*) in Korean white pine tended to increase after heat treatment at 160℃, then decreased gradually afterwards. In royal paulownia, b* values linearly increased with increasing temperature. Overall color change (ΔE*) increased with increasing temperature with higher degree obtained in royal paulownia. Samples with the clamps in both wood species showed lower degree of the change in L*, a*, b and ΔE*. The results of the consumer preferences test showed that the darker colors of heat-treated woods were more preferred by consumers compared to the lighter colors of untreated woods. Consequently, heat treatment could enhance the color properties of Korean white pine and royal paulownia woods for value added products.

The liquid chromatography mass spectrometry (LC-MS)-based metabolomic and lipidomic methodology has great sensitivity and can describe the fingerprint of metabolites and lipids in pork and beef. This approach is commonly used to identify and characterize small molecules such as metabolites and lipids, in meat products with high accuracy. Since the metabolites and lipids can be used as markers for many properties of a food, they can provide further evidence of the foods authenticity claim. Chromatography coupled to mass spectrometry is used to separate lipids and metabolites from meat samples. The research data usually is compared to lipid and metabolite databases and evaluated using multivariate statistics. LC-MS instruments directly connected to the metabolite and lipid databases software can be used to assess the authenticity of meat products. LC-MS has good selectivity and sensitivity for metabolomic and lipidomic analysis. This review highlighted the combination of metabolomics and lipidomics can be used as a reference for analyzing authentication meat products.

Degeneration or defect of articular cartilage is a major predicament and if it is left untreated, it may leadto progressive damage and disability affecting every one disregard of their age. Although nonsurgical managementof articular cartilage injury has remained largely the same over many years, surgical treatment keeps on evolving. Restorative techniques, mainly the cell-based therapies and autologous or allograft transplants continue to expand,giving surgeons more options for biologic reconstruction of the articular surfaces. Hence the field of articular cartilagetissue engineering which seeks to repair, restore and improve injured or diseased articular cartilage functionalityhas aroused deep interest and holds great potential for improving articular cartilage therapy. However despite thisgreat evolution, therapeutic uncertainty in the restoration of damaged cartilage using tissue engineering approachesstill remains unclear for the surgeon treating patients to make evidence-based decisions. This paper will give a generalidea to different level of audiences in understanding the concept of tissue engineering from bench to bed-sideregarding recent developments in this exciting field.
