NASA and the U.S. Department of Defense are conducting programs which support the future vision of “intelligent” aircraft engines for enhancing the affordability, performance, operability, safety, and reliability of aircraft propulsion systems. Intelligent engines will have advanced control and health management capabilities enabling these engines to be self-diagnostic, self-prognostic, and adaptive to optimize performance based upon the current condition of the engine or the current mission of the vehicle. Sensors are a critical technology necessary to enable the intelligent engine vision as they are relied upon to accurately collect the data required for engine control and health management. This paper reviews the anticipated sensor requirements to support the future vision of intelligent engines from a control and health management perspective. Propulsion control and health management technologies are discussed in the broad areas of active component controls, propulsion health management and distributed controls. In each of these three areas individual technologies will be described, input parameters necessary for control feedback or health management will be discussed, and sensor performance specifications for measuring these parameters will be summarized.

Introduction. The crisis state of the domestic economy and a number of other factors require domestic enterprises and other levels of management to take prompt and drastic measures aimed at increasing the level of management. One of the promising and proven directions for increasing the efficiency of the management level is the increase and qualitative growth of the accounting system and the internal control system. One of the most important and difficult areas of accounting and control work (determining the final results of the financial and economic activities of the enterprise and its financial condition) is the accounting and control of liabilities, primarily current ones, this is what determines the direction of this research. The purpose of the paper is to improve the accounting and control of current liabilities by developing measures to eliminate violations and prevent them in the future. The methodological basis was dialectics, philosophical methodological methods of cognition. Results. The paper examines approaches to clarifying the definition of “current liabilities”. The most significant problems of modern economic activity of the domestic economy are investigated: low contractual discipline, crisis of non-payments, global chronic violation of the terms and conditions of payment for liabilities, primarily for current liabilities. A number of measures were proposed to eliminate violations in accounting, control current liabilities and prevent them in the future; non-admission in the practice of economic activity, accounting and control of delays in the terms and conditions of payment for liabilities. The studies have shown the need to improve the level of planning and contractual discipline, financial planning, improving document flow, accounting and control work at the enterprise. Conclusion. The main conclusions of the study are: the need for further research on this issue; introduction of a payment schedule for liabilities; the need to develop a methodology for checking current liabilities by the internal control system, compliance with contractual discipline; scheduled regular inspections of facilities and processes related to accounting and control of current liabilities.

Credit sales are carried out by companies to attract many customers, so that the sales volume  can increase compared to sales in cash. However, credit sales have several risks including uncollectible receivables. Hence, internal control of receivables is very important as receivables, in the future, must be recorded in cash flow. If there are customers who are overdue in payments or fail to  settle their debts due to various reasons, the company’s operational activities will be disrupted.           The purpose of this study is to determine the internal control of trade receivables in minimizing uncollectible receivables in a company.           PT Bostinco is a manufacturing company that produces safes, filling cabinets, roll-o-pack sliding cabinets, fire doors, etc. In its regular sales practice, the company  uses a credit sales system,  preceded by  down payment requirements based on  the agreement between the seller and the customers. As credit sales made by the company will cause trade receivables,  internal control is carried out to minimize the risk of uncollectible receivables.           The results of the study show that internal control of accounts receivable in minimizing uncollectible receivables runs poorly due to the findings of  the original Delivery Order files that are still  discharged. Moreover, the company has some VAT debt arrears which  prevents it from getting the tax invoice number. Unfortunately, there is no penalty agreement for  late payment despite of quite large amount of receivables.   Keywords: Internal Control of Accounts Receivable and Minimize Uncollectible Receivables

Internal control has an important role in accordance with the achievment of good governance, and last but not least for the higher education which internal control is conducted by Inspectorate General (Itjen) and internal audit unit (SPI) in each state own university and polytechnique all around Indonesia. This research uses descrptive qualitative approach with explanatory model in order to deliver the message and analys data from various sources. Since the higher education moved to a new Ministry, the Inspector General put a new paradigm and a brand new internal control mechanism wich involve the internal audit unit in each state own university and polytechnique all around Indonesia as the armth lenghth of their internal control policy, thus, the integrated internal control will be achieved. Role conflict may occur both for Itjen and SPI evnthough in the different context and level. The lack of enacted law regarding the SPI and their rule in detecting and preventing Fraud are triggering the role conflict for them. However, role conflict will not make itjen and SPI give up to their assignment. The model of sinergy is advised in this article and hopefully will give a good contribution for the future integrity working model of Itjen and SPI in the future.

As more and more institutions appear in the financial sector that are considered “too big to fail,” the threat of corporate fraud and its consequences for banks and the economy today has a greater impact than ever before. Fraud trading (speculation) is one of the types of corporate fraud that banks have not succeeded in fighting since it appeared in the spotlight in 1995. Speculators engage in unauthorized trading on behalf of their bank, and the most serious cases have led to the loss of billions and also to the collapse of the Barings Bank. Despite the obvious threat posed by speculation, it seems that banks have failed to establish internal control over it. Cases of unauthorized trading, which led to huge losses for banks, have been repeated for many years. At the same time, the numbers are steadily increasing to frightening amounts. The reason speculation is so controversial in corporate fraud is that, in theory, it does not begin with neglecting the interests of the bank. On the contrary, most of these scammers begin to conduct unauthorized transactions, wanting benefits for the company. But at the same time, the fact remains that after a turning point, when fraudsters try to hide their losses, they already consciously begin to act against the bank. And even then, most of them believe that they will be able to recover their losses and achieve profit and profit for the bank. Thus, the purpose of this article is to analyze the reasons why fraudulent trade has continued over the past two decades and the measures that have been taken to combat it. And you also need to understand how effective these measures are and what can be done in the future to change the situation for the better.

In a near future, many people will be able to visit and stay in the space hotels easier than now days. In this situation, a novel clothes that fit to the special environment will be required. In this paper, we describe the detail of a prototype of “space clothes”, a new clothes design that could solve the appearance and functionality conditions shown below.Conventional clothes especially skirts and loosely designed shirts are often difficult to be worn in space because it restricts wearer’s motion. On the other hand, such clothes are often preferred by women because of their elegance. The both elegance and functionality must be achieved for the clothes of the future space tourists.All the future space tourists should suffer from space sickness and sunburns by ultraviolet rays. Those issues will worsen the experience in the space. Future clothes for space tourists should be able to solve or be able to mitigate them. Based on these conditions, we developed a prototype of clothes for future space tourists(Figure 1(a)). This clothes is carefully designed to achieve both functionality and elegance. In addition, it embedded with bio-informatics display system to share wearer’s health status among other tourists to enable early initial treatment(Figure 1(b)). We believe that this paper could be a good opportunity to initiate the discussion to clear new market of clothes in space.

This study examines whether the effectiveness of internal control over operations and compliance is associated with the likelihood of financial misstatements. Using a unique dataset from Taiwan, we find that the more deficiencies a company has in internal control over compliance, the greater the likelihood that the company’s financial statements will be restated in the future; indeed, severe misstatements are more likely for firms with more internal control deficiencies in compliance. However, we do not find a similar impact involving internal control over operations. As the literature contains little about internal control over operations and compliance, our study contributes by shedding light on the importance of control activities in operations and compliance in regard to the quality of financial reporting.


During this session we are still considering engineering requirements but concentrating on aircraft - airframes, undercarriages, and engines. The aims of this conference were to bring engineers and metallurgists together, and to discuss the design requirements and how the various requirements lead to different priorities. There are unfortunately no simple cases. It is important to note that aircraft designers wish to increase the strength of materials as far as safety and reliability will allow. This is precisely what Rosenhain did in the past and I cannot overemphasize the importance of very close associations between engineers and metallurgists in the aviation business. We will therefore consider the designers requirements, how the metallurgist has been able to help in the past, and what is required in the future.
