Our research task have goal to describe a treaty rhetoric known as 『La Rhétorique ou L'Art de Parler』(1688) which corresponds to a very wide field of which the step is not yet dubious in our country. Thus to study the rhetoric of Lamy borrowed from the thought of Descartes, we left the concept d' origin of language in traditional rhetoric in connection with logic and grammar (in first part). Also the second part is devoted to the tropes and the figures that are modified and deteriorated by the language of passion called 'rhetoric of passion or psychological of figure', etc. And the third part interests in the body of the speech being the character of l' heart. Under the influence of the rhetoric of Lamy, French rhetoric at the 17th century is held for an essential text when one interests in the history of the ideas and rhetoric, marked in its specificity (passion). The project of Lamy registered in the concept of passion like 'manners of speaking'. To close this study, which does one have to retain? The first remark to note is that Lamy founds his rhetoric in opposition to traditional designs dating from the beginning of Aristote. Second remark is the idea that one finds based in famous the books of Dumarsais at the 18th century and Fontanier at the 19th century. Admittedly, Lamy is a true rhetorician, grammairien which interests in the question of passions in the speech forces to reconsider the idea spread since Mr. Foucault, and makes it possible to understand the passage of the Great century at the Century of Lumuères. Even if this opinion is not shared, it will be agreed that the work of Lamy on passions or the phenomena sensory and psychological in the center of the language deserves reflexion.

In order to investigate the information for effective detection and developing of latent fingerprints, we identified fatty acids composition of latent fingerprints on non-porous evidence surface and the chemical changes of latent fingerprint residue after print deposition during 7 months. Fingerprints from eight Korean male donors (aged 29-50 years) and one female donor (aged 36 years) were collected. All fingerprints were found to contain lauric acid (C12:0), myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), elaidic acid (C18:1n9t), oleic acid (C18:1n9c), linoleic acid (C18:2n6c), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9) and docosadienoic acid (C22:2) and primarily palmitic acid (35.45-48.37%), oleic acid (14.84-28.49%), stearic acid (9.71-24.96%) and linoleic acid (7.68-18.8%) occupied 75% of total fatty acids. When the fingerprints were deposited at dark room for 7 months, total fatty acids components decreased about 12-25%. It can be explained that significant degradation of long-chain fatty acids such as elaidic acid (C18:1n9t), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9), and docosadienoic acid (C22:2) resulted in the generation of myristic acid (C14:0), myristoleic acid (C14:1) and pentadecanoic acid (C15:0).

Sweat contents were investigated for using those data to forensic purpose. The experiments of identifying sweat contents were as follow: 1) measurement of amino acids (aspartic acid, serine, glycine etc) by HPLC, 2) anions ($Cl^-$, $F^-$, and $SO{_4}^{2-}$) by IC and 3) trace elements (Cu, Zn, Li, B, etc.) by ICP-MS. Amino acid contents in sweat are varied with individual samples and glycine, threonine, alanine, valine and histidine are detected as the prime one. The detected anions are $Cl^-$(2167~4073 ppm) and $F^-$(454~582 ppm) mostly. Trace elements of Rb, Zn and Cu are detected and those concentrations are relatively very high. The compositions of sweat can be influenced by various factors (diet, anthropometric, characteristics, physical fitness, age, gender and the state of the health).

Windows operating system generates various logs with timestamps. Timestamp tampering is an act of anti-forensics in which a suspect manipulates the timestamps of data related to a crime to conceal traces, making it difficult for analysts to reconstruct the situation of the incident. This can delay investigations or lead to the failure of obtaining crucial digital evidence. Therefore, various techniques have been developed to detect timestamp tampering. However, there is a limitation in detection if a suspect is aware of timestamp patterns and manipulates timestamps skillfully or alters system artifacts used in timestamp tampering detection. In this paper, a method is designed to detect changes in timestamps, even if a suspect alters the timestamp of a file on a storage device, it is challenging to do so with precision beyond millisecond order. In the proposed detection method, the first step involves verifying the timestamp of a file suspected of tampering to determine its write time. Subsequently, the confirmed time is compared with the file size recorded within that time, taking into consideration the performance of the storage device. Finally, the total capacity of files written at a specific time is calculated, and this is compared with the maximum input and output performance of the storage device to detect any potential file tampering.

This study used optical and scanning electron microscopy to analyze the surface oxidation phenomenon that accompanies a γ'-precipitate free zone in a directional solidified CM247LC high temperature creep specimen. Surface oxidation occurs on nickel-based superalloy gas turbine blades due to high temperature during use. Among the superalloy components, Al and Cr are greatly affected by diffusion and movement, and Al is a major component of the surface oxidation products. This out-diffusion of Al was accompanied by γ' (Ni₃Al) deficiency in the matrix, and formed a γ'-precipitate free zone at the boundary of the surface oxide layer. Among the components of CM247LC, Cr and Al related to surface oxidation consist of 8 % and 5.6 %, respectively. When Al, the main component of the γ' precipitation phase, diffused out to the surface, a high content of Cr was observed in these PFZs. This is because the PFZ is made of a high Cr γ phase. Surface oxidation of DS CM247LC was observed in high temperature creep specimens, and γ'-rafting occurred due to stress applied to the creep specimens. However, the stress states applied to the grip and gauge length of the creep specimen were different, and accordingly, different γ'-rafting patterns were observed. Such surface oxidation and PFZ and γ'-rafting are shown to affect CM247LC creep lifetime. Mapping the microstructure and composition of major components such as Al and Cr and their role in surface oxidation, revealed in this study, will be utilized in the development of alloys to improve creep life.

Most if not all research articles published in journals require the author to write an abstract regardless of academic field. However, abstract writing in English is a highly specialized genre on its own. In this light, the purpose of this study is to investigate differences in journal article abstracts written in English by Korean and native English scholars. 90 research paper abstracts written in English by Korean national scholars, US-educated Korean scholars and native English scholars were compared according to rhetorical organization. A generalized rhetorical scheme was used in analysis which was based on Graetz (1985) and Swales (1990): Background-Purpose-Method-Result-Conclusion. In addition, the use of conjunctions as a cohesive device was analyzed based on the categories proposed by Halliday and Hasan (1976). Analyses of the research paper abstracts showed that the majority of the abstracts included the purpose, method and result components. However, while approximately 70 percent of native English writers used research background in the abstract, only 26 percent of Korean national scholars did so. Regarding the use of conjunctions, Korean-national scholars overused and inappropriately used additive and temporal conjunctions. The US-educated Korean scholars showed similar patterns to the native English speakers. The findings obtained here imply that there is a need to provide academic writing instruction of abstracts to non-native scholars.

When illegal transactions are made with bitcoin, it's not easy to track all the bitcoins used in the transaction and seize them. Especially, if criminals distribute illegal transactions by spreading them to several bitcoin addresses, it's difficult to track hidden bitcoins other than confiscated bitcoins even if some bitcoins are confiscated. This paper proposes a method for tracking and monitoring all bitcoin transactions suspected of illegal transactions. This method estimates bitcoin addresses that are highly relevant to crime among all bitcoin addresses that dealing with the address based on the bitcoin address list of the alleged crime, and keeps track of addresses that are relevant to crime and help to investigate illegal bitcoin transaction.

The purpose of this study is to examine the U.S. Coast Guard's origins and powers with respect to the warrantless searches of vessels at sea. In principle, searches and seizures of vessels at sea require a warrant. However, a ship at sea may easily slip away and destroy evidence while authorities attempt to get a warrant. Thus, warrantless searches and safety inspection need to be validated because of the exigent circumstances at the sea. There are also two kinds of exceptions that justify warrantless searches at sea namely, border searhes and administrative searches. These theories in the U.S. will be useful for legislation and law enforcement related to the Korea Coast Guard's mission.
