OPTIMIZATION ACTIVITIES IN A CONTAINER TERMINAL TO REDUCE IDLE TIME IN LOADING-UNLOADING OPERATION

<p><em>In line with the implementation of development in Indonesia, whose main target is in the field of economic development, trade activities are one of the sectors of economic development, constantly developing their role. Therefore, it is necessary to have adequate transportation facilities, both by land, sea, and air. The dynamics of the construction can be seen clearly both in terms of the number of high-rise buildings, vehicles, activity facilities, residential areas, and other infrastructure. This condition requires careful, fast, and precise anticipation from the Regional Governent and various policies in a spatial structure feasibility plan that considers the ability of transportation support as one of the main supports. This study seeks to study and analyze the related handling of idle time at PT Samudera Indonesia Jakarta by optimizing loading and unloading activities on container ships. By using descriptive qualitative methods and samples taken from PT Samudera Indonesia Jakarta, the following results are obtained: Problems in the system The cargodoring are: Difficult to direct the location of container dropping from the ship, The slow process of container dropping from the ship, Limited number of cranes, The occurrence of transportation queues, Limited ability to carry containers for each transport, Required trucks in large quantities, There was a clash between trucks that carry out the process of loading and unloading containers, the difficulty of directing the location of containers if it must be stacked with other containers, the development idea is to make a cargodoring handling system using a headless semi-automatic train, which utilizes seawater power and the conveyor system.</em><em></em></p><p> </p><em>Keywords : <strong>Idle time,</strong><strong>Optimization, Loading, Container, Samudra Indonesia</strong></em>

Study on Risk Management of Epidemic Prevention in High Rise Residential Areas of Urban Community from the Perspective of COVlD-19: A Case Study of L Community in Handan City

Urban community is a basic community and a basic unit of society. Integration of community resources, consolidation of community strength and coordination of community contradictions play an important role in COVID-19 pandemic. Taking human health from the perspective of COVID-19 as the starting point, a community risk assessment standard was established using the Delphi evaluation method. The high-rise residential areas in the L community of Handan City were carried out risk assessment to find out the deficiencies of high-rise residential areas of urban community in the epidemic prevention process, and strategies were put forward to deal with the risk of community epidemic prevention, so as to provide the reference for the improvement of urban community health emergency planning and management in China.

Comparing impact of multi-factor planning layouts in residential areas on summer thermal comfort based on orthogonal design of experiments (ODOE)

The previous studies of outdoor thermal comfort mainly focused on the micro-climate changes caused by urban morphological factors such as street aspect ratio, plot ratio, sky view factor (SVF) et al. As an essential routine to mitigate urban heat island (UHI), vegetation was also discussed by researchers to explore the optimal distribution. However, under the same determined quantity, there is still a blank of the study in how significant each layout factor is to thermal comfort, including the building layout, the pavement layout, and the vegetation layout. This paper followed an orthogonal design of experiment (ODEO) to create various multi-factor layouts in the case of northern China, thoroughly analyzing simulated results based on Physiological Equivalent Temperature (PET) to explain the internal mechanism. Results show that in high-rise residential areas, the layout significance ranking affecting thermal comfort in summer is: buildings, vegetation, pavement. The optimal arrangement is a layout combination of the scattered-form buildings, the grid-form pavement, and the southern vegetation, which can reduce PET of 6.3% maximally during the day. We also found that wind maps are highly consistent with PET maps due to its heat dissipation capability. Another reason for the high PET value is the solar radiation trapping effect, which should be considered with building shade when discussing the relationship between multi-layouts and thermal comfort. The arrangement method can provide a new research direction of urban micro-climate in the future and thus can be employed by decision-makers in the early planning stage.

The Downscaling Study for Typhoon-Induced Coastal Inundation

Typhoons can often cause inundation in lower coastal cities by inducing strong surges and waves. Being affected by typhoon annually, the coastal cities in South Korea are very vulnerable to typhoons. In 2016, a typhoon ‘CHABA’, with a maximum 10 min sustained wind speed of about 50 m/s and a minimum central pressure of 905 hPa, hit South Korea, suffering tremendous damage. In particular, ‘CHABA’-induced coastal inundation resulted in serious damage to the coastal area of Busan where a lot of high-rise buildings and residential areas are concentrated, and was caused by the combined effect of tide, surge, and wave. The typhoon-induced surge raised sea levels during high tide, and the strong wave with a long period of more than 10 s eventually led to the coastal inundation at the same time. The present research focuses a numerical downscaling considering the effects of tide, surge and wave for coastal inundation induced by Typhoon ‘CHABA’. This downscaling approach applied several numerical models, which are the Weather Research and Forecasting model (WRF) for typhoon simulation, the Finite Volume Community Ocean Model (FVCOM) for tide and surge simulation, and the Simulating WAve Nearshore (SWAN) for wave simulation. In a domain covering the Korean Peninsula, typhoon-induced surges and waves were simulated applying the results simulated by WRF as meteorological conditions. In the downscaled domain ranged near the coastal area of Busan, the coastal inundation was simulated blending a storm tide height and an irregular wave height obtained from the domain, in which each height has 1 s interval. The irregular wave height was calculated using the significant wave height and peak period. Through this downscaling study, the impact of storm tide and wave on coastal inundation was estimated.

Measuring Impacts of Urban Environmental Elements on Housing Prices Based on Multisource Data—A Case Study of Shanghai, China

Diverse urban environmental elements provide health and amenity value for residents. People are willing to pay a premium for a better environment. Thus, it is essential to assess the benefits and values of these environmental elements. However, limited by the interpretability of the machine learning model, existing studies cannot fully excavate the complex nonlinear relationships between housing prices and environmental elements, as well as the spatial variations of impacts of urban environmental elements on housing prices. This study explored the impacts of urban environmental elements on residential housing prices based on multisource data in Shanghai. A SHapley Additive exPlanations (SHAP) method was introduced to explain the impacts of urban environmental elements on housing prices. By combining the ensemble learning model and SHAP, the contributions of environmental characteristics derived from street view data and remote sensing data were computed and mapped. The experimental results show that all the urban environmental characteristics account for 16 percent of housing prices in Shanghai. The relationships between housing prices and two green characteristics (green view index from street view data and urban green coverage rate from remote sensing) are both nonlinear. Shanghai’s homebuyers are willing to pay a premium for green only when the green view index or urban green coverage rate are of higher value. However, there are significant differences between the impacts of the green view index and urban green coverage rate on housing prices. The sky view index has a negative influence on housing prices, which is probably because the high-density and high-rise residential area often has better living facilities. Residents in Shanghai are willing to pay a premium for high urban water coverage. The case of Shanghai shows that the proposed framework is practical and efficient. This framework is believed to provide a tool to inform the decisions of housing buyers, property developers and policies concerning land-selling and buying, property development and urban environment improvement.

An Investigation into Requirement of Mobile App for Apartment Residents

High-rise residential buildings, such as apartments, flats, and condominiums, are places of shelter for humans, just like any other types of houses. In a high-rise residential block, the building management plays a vital role in keeping the place pristine and habitable for its residents. Research shows that effective communication and harmonious relationship between the building management and the residents are crucial in maintaining a high-rise residential building. A solution needs to be proposed to alleviate this challenge. Traditionally, the mode of information dissemination and communication between the residents and the building management is done manually using information boards and feedback forms. However, their effectiveness, reliability and reachability are questionable. With the increasing adoption of mobile devices and cloud computing in today’s scenario, the application of mobile technologies such as mobile applications has become viable as a solution to many real-world problems. This research studies how information about the happenings around the high-rise residential area is conveyed to the residents that is deemed as an essential part of the communication between the building management and the residents. This study aims to improve overall communication efficiency between the residents and the management parties of high-rise residential buildings by introducing a mobile app for apartment residents. Two data collection methods - observation and questionnaire - were used in this study and inspections were carried out in this research. Representations were made to investigate how the residents of a high-rise building receive information about happenings around the apartment complex and how the building management and residents committee communicate to share the information. The questionnaire survey was distributed to Facebook groups of high-rise residential buildings, particularly those staying in Sri Bahagia Court and Angkasa Condominium, as well as UCSI University network. Based on the results collected from participants, most of the communication was through physical noticeboard or online social media platforms such as Facebook. Hence, this research investigates the requirement of a mobile app and proposes the development of a mobile app for apartment residents (MyAPT), which addresses the problems of information sharing and further improves communication among the residents and management of high-rise buildings.

Prediction of Outdoor Human Thermal Sensation at the Pedestrian Level in High-rise Residential Areas in Severe Cold Regions of China

The residential areas, as a city’s basic unit, have the closest connection with people’s living environment; the outdoor thermal sensation of residential areas directly affects people’s physical and mental health. This study aims to reveal the relationship between the high-rise residential areas’ building density and wind projection angle, with the winter pedestrian thermal sensation in severe cold regions. In this study, the prediction model of pedestrian-level wind chill temperature of high-rise residential areas is established by using the existed prediction model of the mean pedestrian-level wind velocity ratio of high-rise residential areas and the standard values of air temperature and wind velocity from urban meteorological stations, to perform the quantitative analysis of pedestrian thermal sensation of high-rise residential areas in severe cold regions in winter. Based on this, the winter pedestrian thermal sensation evaluation for the high-rise residential areas of six major cities in the severe cold regions of China is performed by using the prediction model. This paper provides the quantitative guidance and evaluation basis for the high-rise residential areas planning in severe cold regions.

Assessing the Solar Radiation Quantity of High-Rise Residential Areas in Typical Layout Patterns: A Case in North-East China

With the development of energy-saving and emission-reduction, solar energy as a clean energy with excellent characteristics has bright prospects for development and application in residential environment with high energy consumption. With the intensification of land use, there are more and more high-rise residential areas in the city. If the residential construction becomes more compact, the solar radiation of the buildings will be in loss. Therefore, there may exist some restrictive relationship between the residential layout patterns and the solar radiation quantity. Through the multiple response frequency analysis method of SPSS, the study summarizes three typical high-rise residential layout patterns, which are parallel determinant, non-parallel determinant and three-sided enclosure. The Autodesk Ecotect is used to simulate the solar radiation quantity of each building roof and south facade. Last, obtain the relationship between the residential layout index and the solar radiation quantity. The results show that there actually exists certain correlativity between solar radiation quantity and floor area ratio, building density and building height; meanwhile, each annual solar radiation quantity changed by residential layout index has its own variable curve. The results also indicate that three-sided enclosure layout pattern has greater solar radiation potential than parallel determinant and non-parallel determinant. By summarizing the corresponding conclusions, the optimal mode of high-rise settlements with high solar radiation is explored, which can provide reference for further residential planning.

Effects of Landscape Design on Urban Microclimate and Thermal Comfort in Tropical Climate

A climate-responsive landscape design can create a more livable urban microclimate with adequate human comfortability. This paper aims to quantitatively investigate the effects of landscape design elements of pavement materials, greenery, and water bodies on urban microclimate and thermal comfort in a high-rise residential area in the tropic climate of Singapore. A comprehensive field measurement is undertaken to obtain real data on microclimate parameters for calibration of the microclimate-modeling software ENVI-met 4.0. With the calibrated ENVI-met, seven urban landscape scenarios are simulated and their effects on thermal comfort as measured by physiologically equivalent temperature (PET) are evaluated. It is found that the maximum improvement of PET reduction with suggested landscape designs is about 12°C, and high-albedo pavement materials and water bodies are not effective in reducing heat stress in hot and humid climate conditions. The combination of shade trees over grass is the most effective landscape strategy for cooling the microclimate. The findings from the paper can equip urban designers with knowledge and techniques to mitigate urban heat stress.

Estimation of transport demand for residential areas according to their location in urbanized areas

Abstract The present article is addressing the method of estimation of transport demand for residential areas located both within the city boundary and outside. Residential areas are represented by traditional residential districts as well as low-rise buildings with land plots including gardeners’ non-commercial partnerships (hereinafter referred to as (GNCP). The proposed method of transport demand estimation is based upon quantitative characteristics stipulating the aforesaid areas functioning. The authors analyze the effect of area remoteness from the city center and from the nearest arterial street. It should be noted that different types of territories are characterized by intrinsic factors affecting the transport demand. For instance, attendance of large shopping-and- recreation centers will depend only on their area size while quantity of visitors in supermarkets and general stores will be influenced by factors like remoteness form city center and from Arterial Street. This article is addressing empirical dependencies which allow estimating transport demand towards residential areas including also residential areas located within urbanized territories. In the practice of transport computations it is important to perceive occurrence of peak and inter-peak periods on which basis the main computations are being fulfilled; quantitative representation of aforesaid periods may be implemented with the use of diurnal irregularity coefficients representing the percent of territory utilization ratio by hours. Comparison of diurnal irregularity coefficients (based on RMSE analysis) may (i) give answer to the question about similarity of functioning of GNCP and urban residential area and (ii) help to substantiate the fact of population permanent residing within GNCP territories which fact will, in its turn, stipulate presence of permanent shuttle migrations fulfilled with labor purposes. The authors performed comparative analysis of Individual Transport (IT) intensity on the basis of proposed empirical dependencies with in-situ measurement of IT intensity which demonstrated high degree of convergence. The authors compared diurnal irregularity coefficients of GNCP and high-rise residential area which demonstrated substantial convergence on the basis of RMSE analysis (R2=0.67) which fact, in its turn, demonstrates considerable functional similarity between GNCP and residential areas located within administrative boundaries of the city.

The Effects of Residential Area Building Layout on Outdoor Wind Environment at the Pedestrian Level in Severe Cold Regions of China

In recent years, there has been a frequent occurrence of extremely cold conditions which has had a serious impact on the life of residents of buildings in various locations around the world. However, there have only been a very limited number of studies on the effects of residential area building layout on the winter wind environments, which led to a lack of quantitative guidance for residential area planning in severely cold regions. This study aims to reveal the relationship between (1) the residential areas’ building density, floor area ratio, wind projection angle, average building height, and relative position of high-rise buildings, and; (2) the mean wind velocity ratio at pedestrian level in severe cold regions. In this study, the pedestrian-level outdoor wind environments in 24 typical residential areas of Harbin, China, are simulated using ENVI-met software. The results show that the relative position of high-rise buildings in multi-high-level mixed residential areas has little influence on the mean wind velocity ratio, and the maximum difference is 0.04. The factors of building layout have little influence on the mean wind velocity ratio of multistory residential areas. However, a significant linear correlation exists between the mean wind velocity ratio of high-rise residential areas and both the building density and wind projection angle. The prediction model of the mean pedestrian-level wind velocity ratio was then established.

Study on Community Building Between New and Old Residents in High-Rise Residential Areas

Study on Community Building Between New and Old Residents in High-Rise Residential Areas

일본 민설공원 제도의 특성과 시사점

Urban park planning has become difficult due to the lack of municipal funds. Thereupon, a special scheme was imposed for city park planning. Since then, a legal amendment was made for economical improvement and more active participation. However, there are a lot of questions about whether it was a suitable direction for parks and where it should be emphasized for public interest. Base on these concerns, this study examined the basis and characteristics of location, creation, and maintenance of private development parks in Japan, which was the policy model of Korean private parks. Location and space planning of private development parks was made up considering an effective green network and disaster prevention function, and a minimum area was about 1.42ha. The minimum area, 1ha, was established on the basis of considering realistic possibilities, disaster protection, and universal validity. It was also amended to consider the standard of type two mid- to high-rise exclusive residential areas and consultation with regional governance. Finally, it was built on the lowest limit of ordinance of the relevant city; for example, 100% of the floor area ratio, 30% of the building coverage ratio, and the maximum height of 11 stories, etc. For maintenance, private and public sectors were working together. Maintenance fees for 35 years (based on per month) were paid en bloc by the licensee. However, the city was paid for facilities that accompanied excessive maintenance costs. Meanwhile, it seemed difficult to introduce attractive profit facilities because of the limitations in location, usage permission, and introduction equipment; furthermore, there were problems with management authority, and the burden of expenses was deducted. For creating private Korean parks, this study suggested that we should build priority of creating city parks and select appropriate locations first; also, we need to make criteria for location, creation, and standard management rules that are relevant to the whole nation of Korea.

물류수송을 위한 이종 협업 무인 시스템 개발

In this paper, we propose a novel concept foran unmanned delivery service using a cooperative heterogeneous unmanned system consisting of a self-driving car and an unmanned aerial vehicle (UAV). The proposed concept is suitable to deliver parcels in high-density and high-rise urban or residential areas. In order to achieve the proposed concept, we will develop acooperative heterogeneous unmanned system. Customers can order goods using a smartphone application and the order information, including the position of the customer and the order time, and the package is transported automatically by the unmanned systems. The system assigns the tasks suitable for each unmanned vehicle by analyzing it based on map information. Performance is validated by experiments consisting of autonomous driving and flight tests in a real environment. For more evaluation, the landing position error analysis is performed using circular error probability (CEP).

"Fuel Island" design method is adopted to prevent the radiation and spread across functional areas including dining area and commercial area. The maximum heat release rate of fires at various scenes is also determined by different approaches, and then the larger value is taken as the final fire scale.

Variation in baseline corticosterone levels of Tree Sparrow (Passer montanus) populations along an urban gradient in Beijing, China

Rapid urbanization is a major anthropogenic pressure on bird species that rely on vegetation for food and shelter. Since the baseline corticosterone concentration (BCC) in some bird species has been found to increase slightly in response to environmental challenges, we hypothesized that urbanization could also induce an increase in BCC. To test this hypothesis, we compared the BCC of Tree Sparrow (Passer montanus) populations in five urban and two rural habitats and analyzed the relationship between BCC and the degree of urbanization. Here, we show that the BCCs of Tree Sparrow populations were strongly and positively correlated with the degree of urbanization of the habitat. Average BCC of Tree Sparrows from high-rise residential areas and a university campus were significantly higher than those from rural areas, suggesting that Tree Sparrows living in highly urbanized areas have greater environmental challenges than those in rural areas. However, the average BCC of birds from an urban park was not significantly different to that of birds at rural sites and also differed significantly from that of birds at two of the other urban sites. These results suggest that urbanization could pose environmental challenges for Tree Sparrows, a species that appears relatively well-adapted to human-modified environments. The marked variation in BCC between different urban sites indicates that conclusions drawn from data collected at single sites must be interpreted with caution.

Effects of high-rise living on physical and mental development of children.

Effects of high-rise living on infants' development were investigated in 1987-1988 in a high-rise residential area in Tokyo, using questionnaires on the daily behaviors of a total of 1,045 infants, completed by mothers and kindergarten teachers. Infants of high-rise living showed a delayed independence in fundamental daily customs compared with those of low-rise living. This could be ascribed to an over-attachment of mothers of high-rise living with their infants resulting from a reduced number of outings.

On monitoring community noise using arbitrarily chosen measurement periods

An attempt to find out the effectiveness of using short time span measurements to monitor or assess the acoustical environment is summarized in the present study. Long time span noise level recording was carried out in the high-rise residential areas of Hong Kong. The short time span results were then obtained from these records by arbitrarily choosing a time period of a specific length. It is found that there is a high probability that the short time span results can be very much lower than the worst scenario of a site, but the estimations of the energy-based Day–night level and Day–evening–night level are within engineering tolerance. It is also found that taking one additional short time span measurement at a site strategically can improve significantly the assessment outcome for the day time period.

On the addition of two incoherent unsteady noise records of similar statistical structures. Part 2: effects of long time span and diurnal variations

The present study is a follow-up of a previous investigation of the author in an attempt to understand how the statistical structures of noise records will affect that of the resultant noise record formed from their addition. This issue becomes particularly important when statistical indices such as L 10 and L 90 of the resultant noise record are required for planning or assessment purposes. Long time span sound pressure level records were obtained from 18 well-separated independent sites in the high-rise residential areas of Hong Kong. The results obtained from their addition are compared with those of the 25-min record addition done by the author previously. The diurnal variations of the addition results are also discussed. In general, the present results suggest that there is weak correlation between the long time span records. The currently adopted logarithmic addition procedure still over-estimates the noise climate and only limited improvement is found when compared to the results of the 25-min cases. The present results further confirm the importance of the noise statistical structures in the environmental noise impact assessment.
