To prevent accidents in chemical plants, it is important to identify the root cause of the accident and suggest countermeasures. When accident factors are known, eliminating the cause of the accident can increase its prevention. The number of factors, including social factors, in addition to human factors, is increasing. When analyzing the cause of an accident when it is complex, advanced, and the connection between processes is high, there is a growing need to approach it with an integrated system analysis method related to the organization, along with a sequential approach to determine the direct cause of the accident. Several countries have introduced and applied techniques for integrated analysis of accidents from a systematic viewpoint, such as AcciMap and the functional resonance accident model (FRAM) that were developed around 2000. However, it remains difficult to find cases or research results applied in Korea. In this study, accidents in Korean chemical factories are analyzed using systematic accident analysis techniques, and a plan to utilize systematic analysis techniques for future accident investigations is developed.

The right and appropriate system of receiving and transferring goods is needed by the company. In the process of receiving and transferring goods from the central warehouse to the branch warehouse at PDAM Tirta Kerta Raharja, Tangerang Regency, which is currently done manually is still ineffective and inaccurate because the Head of Subdivision uses receipt documents, namely PPBP and mutation of goods, namely MPPW in the form of paper as a submission media. The Head of Subdivision enters the data of receipt and mutation of goods manually and requires a relatively long time because at the time of demand for the transfer of goods the Head of Subdivision must check the inventory of goods in the central warehouse first. Therefore, it is necessary to hold a design of information systems for the receipt and transfer of goods from the central warehouse to a web-based branch warehouse that is already database so that it is more effective, efficient and accurate. With the web-based system of receiving and transferring goods that are already datatabed, it can facilitate the Head of Subdivision in inputing data on the receipt and transfer of goods and control of stock inventory so that the Sub Head of Subdivision can do it periodically to make it more effective, efficient and accurate. The method of data collection is done by observing, interviewing and studying literature from various previous studies, while the system analysis method uses the Waterfall method which aims to solve a problem and uses design methods with visual modeling that is object oriented with UML while programming using PHP and MySQL as a database.

Abstract The shift in power conversion and power management applications to thick copper clip technologies and thinner silicon dies enable high-current connections (overcoming limitations of common wire bond) and enhance the heat dissipation properties of System-in-Package solutions. Powerstage innovation integrates enhanced gate drivers with two MOSFETs combining vertical current flow with a lateral power MOSFET. It provides a low on-resistance and requires an extremely low gate charge with industry-standard package outlines - a combination not previously possible with existing silicon platforms. These advancements in both silicon and 3D Multi-Chip- Module packaging complexity present multifaceted challenges to the failure analyst. The various height levels and assembly interfaces can be difficult to deprocess while maintaining all the critical evidence. Further complicating failure isolation within the system is the integration of multiple chips, which can lead to false positives. Most importantly, the discrete MOSFET all too often gets overlooked as just a simple threeterminal device leading to incorrect deductions in determining true root cause. This paper presents the discrete power MOSFET perspective amidst the competing forces of the system-to-board-level failure analysis. It underlines the requirement for diligent analysis at every step and the importance as an analyst to contest the conflicting assumptions of challenging customers. Automatic Test Equipment (ATE) data-logs reported elevated power MOSFET leakage. Initial assumptions believed a MOSFET silicon process issue existed. Through methodical anamnesis and systematic analysis, the true failure was correctly isolated and the power MOSFET vindicated. The authors emphasize the importance of investigating all available evidence, from a macro to micro 3D package perspective, to achieve the bona fide path forward and true root cause.

AbstractMaterial analysis, specially surface analysis of materials, has been increasingly important. A wide range of surface analysis techniques is available. The techniques are, generally, complementary. There are nuclear and non-nuclear techniques, e.g. microscopy. Nuclear techniques, which are nondestructive, permit analysis for a few microns near the surface. They have been applied to areas such as scientific, technologic, industry, arts and medicine, using MeV ion beams. Nuclear reactions permit to achieve high sensitivities for detection of light elements in heavy substrates and also discrimination of isotopes. We use ion-ion nuclear reactions, elastic scattering and the energy analysis method, where an energy spectrum is obtained of ions from the target for a chosen energy of the incident ion beam. The target composition and concentration profile information contained in the spectrum is computationally obtained through a computer program that has been developed for predicting such energy spectra. Predicted spectra obtained for variations of target parameters are compared with experimental data, giving that information. SEM and TEM are also used.

The authors of the article explore the problem of introducing process and risk-oriented thinking in national organizations. In 2000 the International Organization for Standartization, ISO, announced process approach as the basis principle of management in any organization. It became the embodiment of Deming’s postulate who recommended to consider any activity as a technological process. The authors show the practicability of transition from the functional structure of an organization to integrated process. New ISO 9000:2015 standards reflect presentday challenges and require that organizations should carry out risk assessment and accounting. One of the key objectives of the quality management system is to act as the prevention tool. Preventive action lies in using riskoriented thinking in formulating requirements to the quality management system. The authors introduce the system analysis method in risk management to reveal potential risks and plan preventive action.

Insurance Development

In modern conditions, life insurance plays a crucial role for the economy of the country and its citizens, because it is aimed at financial and social protection of the population through the organization of an integrated system of material security in the event of various events associated with life, health, disability or other events, which can lead to a significant imbalance of family or personal budgets, and a decline in living standards. The main trends of life insurance development in Ukraine presented in the study demonstrate that current processes of globalization have a serious impact on the complications of consumer and savings properties of life insurance through the merger of insurance, credit and investment products. At the same time, in Ukraine, this type of insurance is hampered by a number of factors, due to which it does not become widespread. That is why the article focuses on the problems of life insurance development in the context of financial imbalances and proposes directions for their activation in Ukraine.
