The number of fire and explosion accidents caused by pyrolysis oil and gas at waste plastic pyrolysis plants is increasing, but accident status and safety conditions have not been clearly identified. Therefore, the aim of the study was to identify the risks of the waste plastic pyrolysis process and suggest appropriate safety management measures. We collected information on 19 cases of fire and explosion accidents that occurred between 2010 and 2021 at 26 waste plastic pyrolysis plants using the Korea Occupational Safety and Health Agency (KOSHA) database and media reports. The mechanical, managerial, personnel-related, and environmental problems within a plant and problems related to government agencies and the design, manufacturing, and installation companies involved with pyrolysis equipment were analyzed using the 4Ms of Machines, Management, Man, and Media, as well as the System-Theoretic Accident Model and Processes (STAMP) methodology for seven accident cases with accident investigation reports. Study findings indicate the need for establishing legal and institutional support measures for waste plastic pyrolysis plants in order to prevent fire and explosion accidents in the pyrolysis process. In addition, ensuring safety from the design and manufacturing stages of facilities is essential, as are measures that ensure systematic operations after the installation of safety devices.

A detailed literature review is presented for the applications of the heat pump technologies on the electric vehicles Heating, Ventilation and Air Conditioning (HVAC) system. Due to legal regulations, automotive manufacturers have to produce more efficient and low carbon emission vehicles. Electric vehicles can be provided these requirements but the battery technologies and energy managements systems are still developing considering battery life and vehicle range. On the other hand, energy consumption for HVAC units has an important role on the energy management of these vehicles. Moreover, the energy requirement of HVAC processes for different environmental conditions are significantly affect the total energy consumption of these vehicles. For the heating process, the coolant of internal combustion (IC) engine can be utilized but in electric vehicles, we have not got any adequate waste heat source for this process. The heat pump technology is one of the alternative choices for the industry due to having high coefficient of performance (COP), but these systems have some disadvantages which can be improved with the other technologies. In this study, a literature review is performed considering alternative refrigerants, performance characteristics of different heat pump systems for electric vehicles and thermal management systems of electric vehicles.

Modern technology drives the world, increasing performance while reducing labor and time expenses. Tanzania Atomic Energy Commission (TAEC) tracks employee's levels of exposure to radiation sources using dosimeters. According to legal compliance, workers wear dosimeters for three months and one month at the workplace. However, TAEC has problems in tracking, issuing and returning dosimeters because the existing tracking is done manually. The study intended to develop a Personal Dose Management System (PDMS) that processes and manages the data collected by dosimeters for easy and accurate records. During the requirements elicitation process, the study looked at the existing system. PDMS' requirement gathering included document reviews, user interviews, and focused group discussions. Development and testing of the system were implemented by applying the evolutionary prototyping technique. The system provides a login interface for system administrators, radiation officers, and Occupational Exposed Workers. The PDMS grants TAEC Staff access to monitor individual exposed workers, prints individual and institutional reports and manages workers' information. The system reminds the users when to return dosimeters to TAEC, generate reports, and facilitates dispatching and receiving dosimeters effectively. PDMS increases efficiency and effectiveness while minimizing workload, paperwork, and inaccurate records. Therefore, based on the results obtained from the system, it is recommended to use the system to improve dosimeter data management at the institution.

The purpose of this study was to provide basic information about efficient space use in the dining and bathing area through the analysis of service flowing. Four researchers observed the service flowing and the using behavior at those areas. The results of the study were as follows: Dining service was proceeded as resident moving, waiting, meal serving, dining, moving and arranging in order. The waiting stage was one of the problematic processes since the staffs made the residents wait to) long at a fixed position. The program right before the meal serving will be helpful for reducing tediousness of the elderly residents. Another problem was that the area was not big enough for the meal sowing. The legal regulation Is needed to prescnbe for the size of dining area per resident. The flowing of bathing service was proceeded as staff preparation, moving, waiting, undressing, bathing, drying, dressing, moving and arranging in order. There were more problems in the dressing area than in the bathing area. The elderly with stretcher or wheelchairs had difficulty in entering the narrow doorway. The dressing area was so crowded with the staffs, undressed elderly, dressed elderly, and other laundries. The division of dressing and undressing area is required to avoid the confusion of the users in the area.

Architectural Bureau(建築所, Kunchukso) that Imperial Japan set up in the Dept. of Treasury (度支部, Takjibu) executed many construction works from Oct. 1906 to Aug. 1910. In the meantime, this bureau produced many architectural records. But they were hardly preserved. Because Imperial Japan disposed the architectural records which had the historical value in according to the legal and administrative criteria. Nevertheless, it is important to inquiry precisely the architectural records considerating that the buildings that Architectural Bureau made were the products of government initiated construction and its activities influenced those of similar architectural bureaus after 1910. The results are summarized as follows : First, Architectural Bureau put through all processes from plan, design, executation to examination. Second, Architectural Bureau were producted many architectural records which cotained not only drawings but also various types of documents. Third, Architectural Bureau applied the preservation method at the first time in order to control buildings. Therefore, we can verify many informations that the drawings didn't give by analyzing the architectural records. In conclusion, we can establish the foundation that clarify the facts of buildings under the rule of Japan Imperialism and grasp the meanings if we raise the value of records and draw up the use plan by seeking new the architectural records and dividing them into the several groups on the production organizations.

Recently there have been great interest in the street landscapes, and numerous studies have been investigating shaping processes of urban landscapes, legal systems for scenery management, landscape preference and evaluation techniques. However, there are only few studies investigating how planting types influence on street landscape evaluation and how the relationships among street landscapes are. This study aims to make a guidelines which can be used for securing afforestation in urban settings and improving urban environment. In specific, the results of this study can provide guidelines for urban street design and the base knowledge for identifying appropriate requirements for better street landscapes. We identify factors which make shape certain images of street landscape, and draw physical factors influencing on visual appropriateness through visual landscapes evaluation process. To evaluate landscapes according to planting types, on-the-spot survey at 14 streets in Gang-Nam district were made. The district is under executing street improving projects and shows the most satisfying planting types. To evaluate street landscapes which people experience during their walking, 100m of continuous streets are chosen. The survey sites exclude streets with irregular pattern, are adjacent to large urban parks or are used as parking spaces in part. We evaluated 9 street landscapes classified into 1-line-planting, 2-line-planting and 3-line-planting on the basis of the location of planting and the planting methods.

Due to technological development in the globalized food system, quantitative problems of food supply have been solved, but food risks have expanded from problems in specific regions to global problems. In order to maximize the efficiency of agricultural production, the growth in agricultural production system, procirement of raw materials, establishment of food processing processes and establishment of food supply chain systems are required. Control of hazards requires facility and administrative efforts. In this study, we examined the role of CSR in conjunction with food safety. Food SCM is related to food safety and correlates with the food supply chain. In terms of the triple bottom line theory, CSR is correlated with SCM and it is possible to pursue food safety through corporate CSR and SCM. In this study, it is statistically confirmed that SCM and CSR are in a positive relationship. In the impact of CSR on food safety, it has been confirmed that economic responsibility and legal responsibility take precedence over environmental responsibility and social responsibility. Based on this, we can achieve food safety through SCM and CSR, and we can decide which of CSR activities can be prioritized.
