This paper focuses on the study of a development direction of the industrial security Expert system. First of all, in order to manage Industrial security system, we need to have law, criminology, business and engineering professionals as well as IT experts, which are the multi-dimensional convergence professionals. Secondly, industrial organizations need to have workforce who can perform security strategy; security plan; security training; security services; or security system management and operations. Industrial security certification system can contribute to cultivate above mentioned professional workforce. Currently Industrial Security Expert(ISE) is a private qualification. However, the author argued that it have to be changed to national qualification. In addition, it is necessary that the system should be given credibility with verifying the personnel whether they are proper or not in the their field. In terms of quality innovation, it is also necessary that distinguish the levels of utilization of rating system of the industrial security coordinator through a long-term examination. With respect to grading criteria, we could consider the requirements as following: whether they must hold the degree of the industrial security-related areas of undergraduate or postgraduate (or to be); what or how many industrial security-related courses they should complete through a credit bank system. If the plan of completing certain industrial security-related credits simply through the credit bank system, without establishing a new industrial security-related department, has established, then industrial security study would be spreaded and advanced. For private certification holders, the problem of the qualification succeeding process is important matter. Additionally, it is necessary to introduce the certifying system of ISMS(Industrial Security Management System) which is a specialized system for protecting industrial technology. To sum up, when the industrial security management system links the industrial security management certification, industrial security would realize in the companies and research institutions dealing with national key technology. Then, a group synergy effect would occurs.

This paper proposes an effective technique that is used to automatically extract feature vectors from vibration signals for fault classification systems. Conventional mel-frequency cepstral coefficients (MFCCs) are sensitive to noise of vibration signals, degrading classification accuracy. To solve this problem, this paper proposes spectral envelope cepstral coefficients (SECC) analysis, where a 4-step filter bank based on spectral envelopes of vibration signals is used: (1) a linear predictive coding (LPC) algorithm is used to specify spectral envelopes of all faulty vibration signals, (2) all envelopes are averaged to get general spectral shape, (3) a gradient descent method is used to find extremes of the average envelope and its frequencies, (4) a non-overlapped filter is used to have centers calculated from distances between valley frequencies of the envelope. This 4-step filter bank is then used in cepstral coefficients computation to extract feature vectors. Finally, a multi-layer support vector machine (MLSVM) with various sigma values uses these special parameters to identify faulty types of induction motors. Experimental results indicate that the proposed extraction method outperforms other feature extraction algorithms, yielding more than about 99.65% of classification accuracy.

In this paper, we examine whether the poor performance of distressed firms where banks take equity may occur due to agency problems in banks. By adopting the debt-equity swap, the bank can effectively postpone the occurrence of bad loans form the failure of the distressed firm. As a result, firms with more debt will be more likely to obtain debt-equity swap, regardless of their probabilities of revival. This is not because they are more profitable, but because they have more debt and thus it poses greater risk to the bank. We empirically look into these predictions with the data of 44 workout firms and find the following results. First, debt-equity swap appears to be more applicable especially when the distressed firms are large and when BIS of related banks is low. Specifically, the conditional probability of 'large firms' based on debt-equity swap is 65.52% and the conditional probability of 'bad banks' based on debt-equity swap is 75.86%. Also, as predicted, the performance of these debt-equity firms is poorer than that of non debt-equity firms. The conditional probability of 'large firms' based on posterior failure is 84.62% and the conditional probability of 'bad banks' based on posterior failure is 84.62%. This is consistent with our predictions and is also confirmed through results of the logit regression analysis. Second, when the restructuring is led by 'good banks', the performance of equity-swap firms is superior to that of non equity-swap firms. This result is consistent with that of James(1995). Hence, we can conclude that there may be some agency problems in restructuring distressed firm-especially when distressed firms are large and banks are bad. And these agency problems can reconcile the difference between James' results and Park, Lee, and Jang's.

The purpose of this paper is to see what the problem is and what the direction of the Investment of ELB is after this study has analyzed an achievable possibility for a suggested yield of ELB. It analyzes estimated yields from January in 2010 to June in 2016 for ELB Structures issued during 2015~2016. It carries correlation analysis and regression analysis between ELB yield and minimum guarantee yield, maximum stock price growth limit, participation rate. As the study result, a probability of achievement over 2% yield was below 20% as stock price growth had been inside maximum limit. An estimated average yield of ELB was 1.49% and it was lowed than 1.72% of Bank Deposit in 2015. So a realized yield was not satisfied the expected yield. As the correlation coefficient between ELB yield and minimum guarantee yield was 0.843, the correlation coefficient between ELB yield and maximum limit yield was 0.279, the correlation of minimum guarantee yield was high. The suggestion is that the a realized yield of ELB is lower than Bank Deposit interest and that the probability of stock growth inside maximum limit is low.

Many problems and complaints have been caused by applying the UCP to the standby credit. To solve the problem, International Standby Practices were established. ISP and UCP are similar in that both of them generally regulate the transaction of credit. However, when the ISP is compared with the UCP, the following features are found : 1. In the UCP, when Force Majeure such as acts of God or strikes cause temporary work stoppage, the expiration date cannot be extended. In the ISP, the expiration date can be extended to 30 days afte the place for presentation re-opens for business in the same situation. 2. The UCP does not specify who the issuer of a document must be because there can be many issuers of documents. In the ISP, it is specified that all required documents are to be issued by the beneficiary. 3. In the UCP, compliance between presented documents is required. In the ISP, a discrepancy between presented documents is allowed. 4. In the UCP, if drawings and/or shipments are required by a credit to be made in instalments, and a required drawing/instalment is not made, the credit ceases to be available for any subsequent instalment. In ISP, there is no loss of effect and no influence on the right of beneficiaries, even in the same situation. 5. In the UCP, multiple transfers are not permitted, but partial transfers are. ISP states just the opposite. Multiple transfers are permitted, but partial transfers are not. 6 The UCP obligate each bank (issuer, confirming and nominated bank) to complete their review within a 'reasonable time' but not more than seven banking days. In the ISP, less than three business days is deemed to be not unreasonable and more than seven days is deemed to be unreasonable. 7. ISP, unlike UCP, recognizes that issuers and confirmers may spread their risk through syndication and participation of standby credits. However, the thing to remember is that the ISP should be reviewed carefully before application. If necessary, a partial addition or modifications can be made. Usually, the best advantage of the ISP is given to the issuers. A positive use of the ISP can be made by issuers but, applicants should consider using the UCP to the their rights and duties.

As Internet advances, websites with simpel HTML pages are changing to complex web application systems with enormous contents and various services. With this trend, it is noted that situations where Web accessibility of the old and the handicapped is inhibited are growing. To solve this problem, The Disability Discrimination Act has been enacted since April 2013. This act triggers massive website reorganization efforts. However, in order for the huge and sophisticated web applications and web sites to ensure a web accessibility, a framework is required to throughout the web site development. Based on thorough review of website development methodologies, web accessibility compliance standards, and various web accessibility issues related to website characteristics, this study proposes a practice oriented "Web Accessibility Compliance Framework". The current study also examines the usefulness and value of this framework by applying it to the internet banking development project of W bank and receiving a certificate for high quality website complying web accessibility standards.

As the Korean economy grew, employment expanded steadily, with the number of economically active people increasing and the employment-to-population rate also increasing. However, the working age population started to decline in 2017, and the employment of women and young people has been sluggish. The proportion of non-salaried workers in Korea is much higher than in other OECD countries, and is also excessive, considering Korea's income levels. In addition, the proportion of non-regular workers and the proportion of workers employed at small companies are particularly high among salaried workers. In light of these characteristics of Korean employment, the urgent problems facing the employment structure can be summarized by the deepening dual structure of the labor market, the increase in youth unemployment, sluggish female employment figures, and an excessive share of self-employment. Overall, it is seen that labor market duality is the main structural factor of the employment problems in Korea. Therefore, in order to fundamentally address this employment problem, it is necessary to concentrate policy efforts on alleviating labor market duality.

This study was carried out in order to reduce the installation expense of heating system for greenhouse comparing to geothermal heat pump and develope the coefficient of performance (COP) for a heat pump. For getting plenty of heat flux from geothermal energy. Surface water in river channel was used for getting a lots of geothermal heat by penetrating water through underground soil layer of the river bank that make heat transmission to passing water. The range of water temperature after the process of Ground filtration is 13~18 degrees celsius which is very similar to low heat source of geothermal heat pump system and the plenty amount of heat source from that make the number of geothermal heat exchanging hole and the expense for geothermal heat exchanger construction reduced. Drainage well is also used for returning filtration water to the aquifer that keep the water good recirculation from losing geothermal heat and water resource. For the COP improvement of Heat pump, thermal storage tank with separating insulation plate according to the temperature difference make the COP of Heat pump that is similar to thermal storage tank with diffuser. Developed thermal storage tank make construction expense cheaper than customarily used one's. and that sand filter and oxidation sand (FELOX) are going to be used for improving ground filtration water quality that make heat exchanger efficiency better. All above developed component skill are going to be set on the Ground filtration water source heat pump system and applied for medium, large scale for protected greenhouse in riverside area and on-site experiment is going to do for optimizing the heating system function and overcome the problem happening in the process of on-site application afterward.

It has been raised a number of administrative ethic questions nevertheless of institutional strategy. It's even worse rather than solved. Especially, because of a distinctive family calture tradition that forming intimate bond, we're carrying lots of possibility of public corruption. As in the case of Busan Saving Bank recently, many of high-ranking officials are scouted to lawferm or business interest company After that this ex-officials exert their influence over government office. terminating public corruption. Lenient law enforcements as in the case of sponser prosecutor, social welfare budget embezzlement result in public distrust about anticorruption policy of government In conclutsion, for a best function of public service ethic system it's important to improve institutional problem constantly.
