높은 비강도와 산화성 및 환원성 분위기에서의 탁월한 내식성 등으로 무기체계에 적합한 소재인 타이타늄은 1790년 영국의 목사 Gregor가 원소를 발견한지 156년이 지난 1946년에서야 비로소 첫방탄시험이 미국의 실험실에서 이루어지게 되었다. 그러나 타이타늄의 높은 화학반응성과 높은 융점($1670^{\circ}C$)때문에 상업적으로 광범위하게 사용되는 것은 더디게 진행되어 왔다. 최근 선진국에서는 타이타늄 재료의 지상무기체계 적용이 광범위하게 검토되어 진행되고 있다.

Steganography is being used as a means of secret communication for crimes that threaten national security such as terrorism and espionage. With the development of computers, steganography technologies develop and criminals produce and use their own programs. However, the research for steganography is not active because detailed information on national security cases is not disclosed. The development of investigation technologies and the responses of criminal law are insufficient. Therefore, in this paper, the detection and decoding process was examined for steganography investigation, and the method was analyzed for 'the spy case of Pastor Kim', who was convicted by the Supreme Court. Multiple security devices were prepared using symmetric steganography using the pre-promised stego key. Furthermore, the three criminal legal issues: (1) the relevance issue, (2) the right to participate, and (3) the public trial issue a countermeasure were considered in national security cases. Through this paper, we hope that the investigative agency will develop analysis techniques for steganography.

목적 : 발성훈련을 받지 않은 각각의 직업적 음성 과사용집단의 음성분석에 대한 연구는 많이 보고되었지만, 이들 집단간의 음성분석을 통하여 각 집단의 음성문제를 비교한 연구는 미흡하다. 따라서 발성훈련을 받지 않은 직업적 음성 과사용집단의 음성 증상 및 음향학적 분석결과를 정상인과 비교함으로써 각 집단간 음성장애의 양상에 대하여 알아보고자 하였다. 대상 및 방법 : 음성장애에 대한 설문조사, 음향적 분석 및 성대화상술검사를 통하여 직업적 음성 과사용집단으로 분류되는 목사, 여자 교환수 및 고교 남녀교사를 증상 및 이학적 검사상 음성장애 소견을 보이지 않는 성인 남녀와 비교하였다.

This study is carried out to investigate the printing culture in current Chollanamdo province. Searching the publication in Naju during the Chosun dynasty, 89 titles were found, where publication had begun from early Koryo dynasty. Active Publication was initiated from the era of King Jungjong and many books were published in 16th and 19th centuries. Many Confucian books were published dominantly in the first half of the Chosun dynasty, and collective literature and genealogical records in the later half. In the first half of the dynasty, most of books were published by the order of a king, the officer of province, or an individual, and, in the later half, increasingly collective literature and genealogical records were published by an individual or a family. Also woodblocks were used in the first half of the dynasty, wooden types in the later half.

Objectives : To compare the objective differences in voice quality and voice problems between clergies and normal male control group. Materials and Methods : The sustained vowel sound of 46 clergies and 40 normal persons were analyzed, using a videostroboscopy and acoustic analyzer. Together with these analyses, a questionnaire associated with current and past voice problems was handed over to the patients. Results : The most common symptom in subjective group was the voice fatigue. Stroboscopic findings in subjective group were as following 23 cases(50%) of pachydermia, 17 cases(37%) of phase difference, 12 cases(25%) of anterior-posterior contracture, 6 cases(13%) of vocal polyp and 3 cases(7%) of vocal nodule. The mean maximal phonation time in clergies was 17.8 seconds and in control group was 19 seconds. litter, pitch perturbation quotient and shimmer were significantly increased in subjective group than in control group(p<0.05), but there were no significant differences between two groups in fundamental frequency, vFo, amplitude perturbation quotient and noise to harmonic ratio. Conclusion : In the clergies using loud and forceful voice, vocal polyp and functional voice disorder findings were frequently noted in stroboscopic examination. litter and shimmer, reflecting the roughness of voice, were increased in acoustic analysis. Therefore, clergies, classified into untrained professional voice users, need professional career guidance and counseling.
