This study proposes a mathematical model for multi-period surgical scheduling problem with capacity constraint over a time horizon. The goal is to schedule a list of patients who must undergo various kinds of operations by different eligible hospitals. In particular, each operation must be performed in a particular time period and different operations of one patient can be performed by different eligible hospitals. In addition, each hospital has limited surgery capacity for each time period. The problem is formulated with a multi-objective model using the weighted sum approach of two objectives: minimization of makes pan and minimization of total least preference assignment score. The experiment is executed using the simulated data according to the real treatments of cleft lip and palate patients. The results show that the model yield the correct assignment and operation sequence respected to all constraints. Thus, this proposed mathematical model can be further used as smart decision tool in surgical scheduling in hospital network.
提出了一种具有容量约束的多周期手术调度问题的数学模型。目标是安排必须在不同合格医院接受各种手术的患者名单。特别是,每次手术都必须在特定的时间段内进行,并且同一患者的不同手术可以由不同的合格医院进行。此外,每家医院在每个时期的手术能力有限。该问题是一个多目标模型,使用两个目标的加权和方法:最小偏好分配分数和最小偏好分配分数的最小化。根据实际的唇腭裂患者的治疗情况,利用模拟数据进行实验。结果表明,该模型在考虑所有约束条件的情况下,给出了正确的分配和操作顺序。因此,该数学模型可进一步作为医院网络手术调度的智能决策工具。

This study examines the effect of good corporate governance and financial performance on the value of state-owned enterprises (SEOs). The population of this study was all companies listed on the Indonesia stock exchange, with a sample of 20 SEOs companies in 2015-2019. The independent variables in this study were Good Corporate Governance with the Independent Board of Commissaries and the Audit Committee and financial performance with the Return on Equity proxy. The dependent variable in this study was the value of SEOs with the price to book value proxy. Hypotheses were tested using SPSS 21.0 software, and data were analysed using multiple linear regression tests. This study found that the Independent Board of Commissaries had a negative and significant effect on the value of SEOs; Audit Committee had a positive and significant effect on the value of SEOs. On the other side, ROE has a negative and insignificant effect on the value of SEOs.

Shipyard is a specialised facility equipped with various tools to support the process of building, repairing and maintaining ships. There are several types of variant ships, such as military ships, tourist boats, cargo ships and passenger ships. Apart from being a place for shipbuilding, shipyards are utilised to conduct several activities, such as ship design, equipment installation, plate installation, feasibility tests and classifications. There are many production activities and flows that allow for potential waste problems that impact labour usage, product quality, costs, and production time. This research aims to identify waste in shipbuilding production lines through a lean manufacturing approach. The lean manufacturing approach is one of the ways in shipyards to observe the level of waste in the production process to reduce unnecessary activities in the production process, which can increase production efficiency and effectiveness. This study approach begins with identifying waste in the production line through mapping on each line so that activities with no added value are identified. On the basis of the results of identification using the waste assessment model (WAM) method, which consists of a waste relationship matrix (WRM) and a waste assessment questionnaire (WAQ), waste is obtained, namely inventory (27,20%), overproduction (20.24%), defective products (20.04%), motion (12.47%), transportation (9.23%), waiting time (7.46%) and process (3.37%)
造船厂是一个专门的设施,配备了各种工具来支持船舶的建造、修理和维护过程。有几种类型的变型船,如军舰、旅游船、货船和客船。除了作为造船场所外,造船厂还用于进行多项活动,例如船舶设计、设备安装、钢板安装、可行性测试和分类。有许多生产活动和流程允许潜在的浪费问题,影响劳动力使用,产品质量,成本和生产时间。本研究旨在通过精益制造方法来识别造船生产线上的浪费。精益制造方法是造船厂观察生产过程中浪费水平的一种方法,可以减少生产过程中不必要的活动,从而提高生产效率和效益。该研究方法首先通过绘制每条生产线的地图来确定生产线上的浪费,从而确定没有附加价值的活动。根据由废品关系矩阵(WRM)和废品评估问卷(WAQ)组成的废品评估模型(WAM)方法的识别结果,得到废品分别为库存(27.20%)、生产过剩(20.24%)、次品(20.04%)、运动(12.47%)、运输(9.23%)、等待时间(7.46%)和工艺(3.37%)。

Diabetes is among the major public health problem especially in developing countries which cause by abnormal insulin secretion in human body. It is a common disease that can led to several health complications and mortality. In Malaysia, most of the cases are categorized as Diabetes Mellitus (DM) Type II. Patients with diabetes increases from year to year due to unhealthy lifestyles e.g. smoking, overweight and hypertension. Therefore, this study meant to identify the influential factors that may contribute to DM Type II by comparing the performance of different data mining approaches. Between April 2017 and November 2018, 684 patients from a public clinic participated in this retrospective cross-sectional study. Four predictive models involved in the study are Logistic Regression, Decision Tree, Naïve Bayes, and Artificial Neural Network (ANN). The error measures (Average Squared Error and Misclassification Rate) with ROC Index are used to evaluate the performance of the models. Results show that the performance of Logistic Regression-Stepwise outperformed to other predictive models with classification accurateness of 73% and able to predict positive outcome (Y=1) correctly by 90%. The significant inputs that affect DM Type II prediction (Y=1) are Hypertension and Glycated Hemoglobin (HbA1c) given the Root Mean Squared Error (RMSE) of model is 0.424. The importance of study may be able to contribute in improving the strategies and planning on diabetes diseases in Malaysia.
糖尿病是由人体内胰岛素分泌异常引起的重大公共卫生问题之一,在发展中国家尤为突出。这是一种常见的疾病,可导致多种健康并发症和死亡。在马来西亚,大多数病例被归类为糖尿病(DM) II型。由于吸烟、超重和高血压等不健康的生活方式,糖尿病患者逐年增加。因此,本研究旨在通过比较不同数据挖掘方法的性能来确定可能导致糖尿病II型的影响因素。在2017年4月至2018年11月期间,来自一家公立诊所的684名患者参加了这项回顾性横断面研究。四种预测模型涉及的研究是逻辑回归,决策树,Naïve贝叶斯和人工神经网络(ANN)。使用误差度量(均方误差和误分类率)和ROC指数来评估模型的性能。结果表明,Logistic Regression-Stepwise的分类准确率为73%,预测阳性结果(Y=1)的准确率为90%,优于其他预测模型。考虑到模型的均方根误差(RMSE)为0.424,影响II型糖尿病预测的重要输入(Y=1)是高血压和糖化血红蛋白(HbA1c)。研究的重要性可能有助于改善马来西亚的糖尿病战略和规划。

The increasing number of tourist destinations in the world has led to an increase in the number of tourists and their supporting industries, such as the hotel industry. This increase should not have a negative impact on the natural environment and people who live near tourist destinations. Sustainable Industrial Performance (SIP) is one indicator to find out whether industrial development has an impact and becomes a benchmark for industry sustainability in the natural and social environment. Sustainable Industrial Performance (SIP) is measured from three (3) factors, namely economy, natural environment, and socio-culture. Pro-Environment Behavior (PEB) is one indicator of initiatives and efforts made by people who work in the sector/industry to continue to maintain the sustainability of the surrounding environmental conditions. Green Marketing Mix (GMM) is a variable commonly used by marketing people in marketing a product, be it goods or services. Green Marketing Mix (GMM) provides characteristics about the importance of creating goods or services with green principles. This research is expected to be one of the green practice concept models, namely activities to create and manage industries with the concept of sustainable business, namely the benefits of sustainable (economic) business, sustainability for the natural environment, and sustainable for the social environment of the hospitality industry
世界上旅游目的地的增加导致了游客数量的增加及其配套产业,如酒店业。这种增长不应该对自然环境和居住在旅游目的地附近的人们产生负面影响。工业可持续发展绩效(Sustainable Industrial Performance, SIP)是衡量工业发展是否产生影响的指标之一,是衡量工业在自然环境和社会环境下可持续发展的基准。可持续工业绩效(SIP)是从经济、自然环境和社会文化三(3)个因素来衡量的。环保行为(PEB)是一个指标,显示在该部门/行业工作的人员为继续维持周围环境的可持续性而采取的措施和作出的努力。绿色营销组合(GMM)是营销人员在营销产品(无论是商品还是服务)时常用的一个变量。绿色营销组合(GMM)提供了以绿色原则创造商品或服务的重要性的特征。本研究预计将成为绿色实践概念模型之一,即以可持续经营的概念创建和管理行业的活动,即可持续(经济)经营的效益,自然环境的可持续性,以及酒店业的社会环境的可持续性

This study empirically examines and analyzes the impact of several macroeconomic indicators on economic growth, namely the extent to which the variables of poverty, human development index (HDI), foreign direct (FDI) and domestic investments (DMI) affect gross regional domestic product (GRDP) at constant prices in 2010 according to expenditure in Indonesia. By using panel data regression and data sourced from 32 provinces throughout Indonesia, the results show that poverty has a negative but not significant effect, FDI has a positive and significant effect, and HDI has a positive and significant effect. On the other hand, Domestic Investment has a positive but not significant effect on GRDP. In an effort to increase the value of GRDP, HDI, and investment (FDI and HDI) that can reduce poverty, the government, the private sector, and the community play an active role in cooperating in planning and implementing effective and efficient strategic program activities, including maintaining social security stability and politics, sustainable reform in all sectors by encouraging the use of domestic products, empowering elements of society including Micro, Small and Medium Enterprises, facilitating various vocational skills training for productive workers and drafting investment-friendly licensing governance regulations. The development of human resources must accompany economic development to reduce the negative impact of economic growth.
本研究实证检验和分析了几个宏观经济指标对经济增长的影响,即贫困、人类发展指数(HDI)、外国直接投资(FDI)和国内投资(DMI)等变量对印尼2010年按固定价格计算的区域国内生产总值(GRDP)的影响程度。通过面板数据回归和来自印尼32个省份的数据分析,结果表明贫困具有负向且不显著的影响,FDI具有正向且显著的影响,HDI具有正向且显著的影响。另一方面,国内投资对gdp有正但不显著的影响。为了提高能够减少贫困的gdp、人类发展指数和投资(FDI和人类发展指数)的价值,政府、私营部门和社区在合作规划和实施有效和高效的战略项目活动方面发挥积极作用,包括维护社会安全稳定和政治,通过鼓励使用国内产品在所有部门进行可持续改革,赋予包括微型、中小型企业在内的社会要素权力,促进生产工人的各种职业技能培训,起草有利于投资的许可治理条例。人力资源的开发必须伴随着经济的发展,以减少经济增长带来的负面影响。

Poverty is one of the macro problems faced by all countries. These problems have different solutions depending on the character of the poor population in the country. One of the proposed solutions is to control prices so that the level of public consumption is maintained. The purpose of the study was to analyze the effect of rice prices on poverty and to map the condition of rice price movements related to poverty in provincial capitals in Indonesia. This study uses panel data from 34 provincial capitals in Indonesia from 2011 to 2020. The data was collected from the Central Bureau of Statistics of Indonesia and uses a panel regression model and important performance analysis (IPA). The results of this study indicated that the price of rice positively affects poverty in provincial capitals in Indonesia. The IPA results show that most provincial capitals in Indonesia are in areas with low poverty rates accompanied by low rice prices and areas with poor people but tend to have high rice prices compared to the average price of rice. It concludes that rice greatly influences the consumption needs of the people of provincial capital cities in Indonesia. This finding shows the importance of maintaining the stability of rice prices due to the large influence of rice price movements on the increase in the percentage of poor people. Suggestions should be given for subsidized rice distribution in areas with high prices.
贫困是世界各国共同面临的宏观问题之一。这些问题有不同的解决办法,取决于该国贫困人口的特点。提出的解决办法之一是控制价格,以维持公共消费水平。这项研究的目的是分析米价对贫穷的影响,并绘制印度尼西亚省会城市与贫穷有关的米价变动情况。本研究使用2011 - 2020年印尼34个省会城市的面板数据。数据从印度尼西亚中央统计局收集,并使用面板回归模型和重要绩效分析(IPA)。本研究结果显示,稻米价格对印尼省会城市的贫穷有正面影响。IPA的结果显示,印度尼西亚的大多数省会都位于贫困率低、米价低的地区,以及人口贫困但米价往往高于平均米价的地区。它的结论是,大米极大地影响了印度尼西亚省会城市人民的消费需求。这一发现表明,由于米价变动对贫困人口百分比的增加有很大影响,因此保持米价稳定的重要性。对高粮价地区的大米补贴分配提出建议。

These problems have different solutions depending on the character of the poor population in the country. One of the proposed solutions is to control prices so that the level of public consumption is maintained. The purpose of the study was to analyze the effect of rice prices on poverty and to map the condition of rice price movements related to poverty in provincial capitals in Indonesia. This study uses panel data from 34 provincial capitals in Indonesia from 2011 to 2020. The data was collected from the Central Bureau of Statistics of Indonesia and uses a panel regression model and important performance analysis (IPA). The results of this study indicated that the price of rice positively affects poverty in provincial capitals in Indonesia. The IPA results show that most provincial capitals in Indonesia are in areas with low poverty rates accompanied by low rice prices and areas with poor people but tend to have high rice prices compared to the average price of rice. It concludes that rice greatly influences the consumption needs of the people of provincial capital cities in Indonesia. This finding shows the importance of maintaining the stability of rice prices due to the large influence of rice price movements on the increase in the percentage of poor people.

Mangrove offers a unique and functional characteristic that proves to be beneficial to its surrounding ecosystem. It also benefited the local communities positively in the socio-economic growth via the increase in ecotourism product varieties. Ecotourism activities must not further deteriorate, but, be able to protect and preserve the mangrove ecosystem via a deliberate mangrove ecosystem management. In the effort to conserve mangrove ecosystem, increase public awareness and promote socio-economic growth, this study therefore seeks to highlight the existing ecotourism product (physical products, activities, facilities and services) at Ketam Island Mangrove Forest, Selangor, Malaysia and proposed ecotourism product suitable to feature mangrove forest. With sustainable development, a conceptual design is proposed for the future development of ecotourism research center and its urban enclave at the location, supplementing suitable ecotourism product to the existing product. A site survey of the location is conducted to observe the mangrove ecosystem. Further information is collected from supporting existing publications. Computer software such as AutoCAD and Adobe Photoshop are used to draw out the 2-Dimensional, 3-Dimensional, and render the proposed design to visual representations. Significantly, the supplementary ecotourism product conserves the mangrove ecosystem, promote socio-economic growth and benefit all stakeholders; visitors, local community.
红树林提供了一种独特的功能特征,被证明对周围的生态系统有益。通过增加生态旅游产品的种类,对当地社区的社会经济增长也有积极的好处。生态旅游活动不能进一步恶化,而是能够通过有计划的红树林生态系统管理来保护和保存红树林生态系统。为了保护红树林生态系统,提高公众意识,促进社会经济增长,本研究旨在突出马来西亚雪兰莪吉丹岛红树林现有的生态旅游产品(实物产品、活动、设施和服务),并提出适合红树林的生态旅游产品。在可持续发展的前提下,对生态旅游研究中心及其周边城市飞地的未来发展提出概念设计,在现有产品的基础上补充适宜的生态旅游产品。对该地点进行了实地调查,以观察红树林生态系统。从支持现有出版物中收集进一步的信息。计算机软件如AutoCAD和Adobe Photoshop被用来绘制二维和三维,并将建议的设计呈现为视觉表示。重要的是,补充生态旅游产品保护红树林生态系统,促进社会经济增长并使所有利益相关者受益;游客,当地社区。

Oil and Gas (O&G) industry is one of the riskiest, most dynamic and challenging industries and plays a vital role in every nation’s economy. Like any other major industry, O&G is exposed to a host of both predictable and unpredictable risks. Joint venture projects (JVP) are often regarded as risky businesses as there is a high failure rate among them because of the complexities involved. This paper aims to identify the critical risk factors (CRFs) of JVPs for O&G between Malaysia and Thailand. Via systematic literature review (SLR) the risk factors for O&G and JVPs around the globe are identified and a set of questions relating to them designed and used in a pilot study. A total of 15 respondents from different background experiences working in O&G JVPs were requested to answer the designed questionnaire during the pilot study. The data collected involves 170 respondents currently working or have worked in O&G JVPs. The relative importance index (RII) for each risk factor’s (RF) value was quantified and the RFs ranked based on the value. A RII value exceeding 60% is considered to have agreement and of importance to the respondents. The RII value can be used as an indicator to rank the RFs from the most to the least critical. The CRF categories determined in this study are environmental, cultural and social, and organisation. Under environmental, the main CRFs are losses due to fluctuations in exchange rates/interest rates. For cultural and social, the main CRFs are problems associated with cultural differences and cooperation. Organisational issues are related to organisational fit, incompetent project management team, difficulty in finding and keeping skilled workers, and low worker productivity.
石油和天然气(O&G)行业是风险最大、最具活力和挑战性的行业之一,在每个国家的经济中都扮演着至关重要的角色。与其他主要行业一样,油气行业也面临着许多可预测和不可预测的风险。由于合资项目的复杂性,其失败率很高,因此通常被认为是高风险的业务。本文旨在确定马来西亚和泰国之间油气jvp的关键风险因素(CRFs)。通过系统文献综述(SLR),确定了全球油气和jvp的风险因素,并设计了一系列与之相关的问题,并在试点研究中使用。在试点研究中,共有15名来自不同背景和经验的受访者在油气jvp工作,他们被要求回答设计的问卷。收集的数据涉及170名受访者,他们目前或曾经在油气合资企业工作。量化各危险因素(RF)值的相对重要性指数(RII),并根据该值对各危险因素进行排序。RII值超过60%被认为对受访者具有一致性和重要性。RII值可用作指标,对RFs进行从最重要到最不重要的排序。在本研究中确定的CRF类别包括环境、文化及社会,以及组织。在环境项下,主要的crf是由于汇率/利率波动造成的损失。对于文化和社会而言,主要的crf是与文化差异和合作有关的问题。组织问题与组织适合度、不称职的项目管理团队、难以找到和留住熟练工人以及工人生产率低有关。
