  • In this paper, the peak finding algorithms corresponding to the Autocorrelation Function (ACF), which are widely exploited for detecting the pitch of voiced signal, are proposed. According to various researchers, it is well known fact that the estimation of fundamental frequency (F0) in speech signal is not only very important task but quite difficult mission. The proposed algorithms, presented in this paper, are implemented by using many characteristics - such as monotonic increasing function - of ACF function. Thus, the proposed algorithms may be able to estimate both reliable and correct the fundamental frequency as long as the autocorrelation function of speech signal is accurate. Since the proposed algorithms may reduce the computational complexity it can be applied to the real-time processing. The speech data, is composed of Korean emotion expressed words, is used for evaluation of their performance. The pitches are measured to compare the performance of proposed algorithms.

  • This research was conducted as a part of research project entitled 'A Fact-finding Survey of Management of Vocational Training Institutes and the Development of Training Program Model for their CEO'. The purpose of this paper was to investigate developing strategies for vocational training institutes in three sector; public institute, private institute and private academy for life long education and to develop practical and professional programs based on competencies model of CEO. The major subjects of this paper were developing strategies of three type of vocational training institutes, exploration of competencies of CEO, and training program for CEO. Delphi method was applied two times. The panel consists of 30 experts who relate to vacational training. The panel of experts emphasized the different own mission and function among three type of vocational institutes. Public institutes support the government policy and private institutes and academy. Private institutes develop specialized training programs that reflect the regional demand. Private academies focus on short-term service training. To recognize changing vocational training policy, to develop vision of institute, ethical mind and sense of mission and so on are presented as competencies of CEO.

  • The fact that since Internet has been spreaded widely to people, Many security problems also have been grown too much. Due to sudden growth, administrator's responsibility for secure network and services has been growing more and more. This paper represents how to prevent account which didn't use for long period on multi domains environment using service log analysis. hence administrator can find security hole on systems and can dealing with it. The Service Log Analyzer is that loading log file which are written by each service and analyzing them. as a result it makes a list named Used User List contains a number of account names which uses specific services. When the time has come - means cron job schedule time, User Usage Shifter is the next runner. it's mission is finding the person who didn't used service for a specific period of time. Then modifying the expire day of the account information.

  • The beginning that the 'Obstruction of Justice' in the United States is commonly known to Korea is through the impeachment of former president W. J. Clinton in 1998. The 'Obstruction of Justice' in the federal law of the United States is comprehensively provided with a general and a particular rule laying emphasis on the obstruction of legal judiciary proceedings. But, according to the Korean Criminal Act and court decisions, there are no such system like the 'Obstruction of Justice' in the United States. In this result, in terms of the criminal-judicial system, some cases even telling a lies has more benefits than revealing the truth and it is discouraged to cooperate the achievement of judicial justice, which make difficulties in investigation and realizing real truth. For this reason, the Ministry of Justice in Korea makes efforts to introduce the 'Obstruction of Justice'. Nevertheless we should examine from all angles that the introduction of 'Obstruction of Justice' is indeed the alternative in our circumstances. Most of the discussions on the introduction of 'Obstruction of Justice' and also the revised bill of the Ministry of Justice are questions of 'False Statement of Suspect and Witness' for investigation of investigative agency, rather than for the introduction of a general rule on the 'Obstruction of Justice'. The introduction of 'False Statement of Suspect and Witness' for investigation of investigative agency needs to consider concern about human rights infringement and witness protection system should be reinforced in the first place. In other words, the introduction of 'False Statement of Suspect and Witness' for investigation process of investigative agency is undesirable now.

A Study on the Current Fire Insurance Subscription and Solutions for Ensuring the Safety of the Traditional Market (전통시장 안전성 확보를 위한 개선방안: 화재보험 가입실태를 중심으로)

  • Concerning the risk factors of the outbreak of a fire in a traditional market, most of those markets are located in downtown areas or residential areas; thus, although their location may be favorable in terms of marketability, they face a potential risk in that a fire may develop into a large blaze owing to poor environment or the absence of facilities prepared for disaster during a fire. Moreover, as many people are densely poised in the markets, it is very probable that a fire may occur owing to the excessive use of heaters in the winter as well as the reckless use of electric and gas facilities. It seems that traditional markets encounter difficulty being insured against fire, because of their vulnerability and that the vast majority of small-scale sellers are likely to suffer mental anguish and tremendous physical injury in case of a fire. However, most of those sellers in the traditional markets are hand-to-mouth sellers, and they lack awareness of safety concerns and have insufficient experience in safe facility management. As small-scale sellers constitute the majority in the traditional market, the subscription rate of fire insurance in most of the traditional markets is low for the reasons of their needy circumstances and their financial burden. Statistically, the subscription by street vendors is non-existent; therefore, these vendors have a fairly limited access to indemnification after fire damage. Because of these problems, this study's purpose is to identify the current level of insurance subscription by these markets, which are exposed to poor facilities and vulnerability to fire. In order to fix this, it appears that shop owners and consumers will have to band together. For this study, we executed a fire policyholder fact-finding mission at traditional markets with approximately 108 and 981 stores. The research method was executed by an investigation using one-on-one individual interviews using a questionnaire. The contents investigated current insurance subscriptions. The method of analysis looked at the difference of insured amount according to volume size through cross-tabulation of the difference of insured amount by possession form, difference of insured amount by market form, difference of insured amount by category of business, difference of insured amount by market size, etc. Furthermore, the study should be used to propose solutions for problems through theoretical review with the use of a literature research, because the field case study was through interviews with the persons concerned, and the survey of the current insurance subscriptions by traditional market shopkeepers. The traditional market would generally have difficulty affording fire insurance. Fire insurance subscription rates of most of the market proved to be inactive, because of the economic burden of payment. Lack of funds is thought to be the main factor that causes a lack of realization about the necessity of fire insurance. In addition to expensive insurance premiums, sometimes, the companies' valuation of the businesses is lower than their actual valuations, and they do not pay out enough during a claim. The research presents an improvement plan that, when presented at the traditional markets, may strengthen their ability to procure fire insurance through the help of the central government. Researchers connected with the traditional market mainly accomplish the initial research. However, although this research has its limitations, it offers considerable benefits. For future researchers, I would suggest looking at several regions for comparison.
