Jo, Jinsu & Park, Jae-hyun. 2017. “Educational Direction by User Perception Type for Military Slangs and Unfamiliar Sino-Korean Words”. The Sociolinguistic Journal of Korea 25(1). 213~238. The purpose of this study is to suggest an educational direction about military slangs and unfamiliar Sino-Korean words used in the military considering the need for refinement and acceptability of the language users. To this end, military personnel, the users of the military language, have been surveyed to examine their use and views of the military language, principally military slangs and unfamiliar Sino-Korean words. Focus-group interviews have also been performed to make an in-depth analysis on their language practice. According to the survey results, the perceived need for refinement is high but acceptability is remarkably lower than the perceived need for refinement. While respondents agree that the suggested terms need to be refined, they think that the purified words or alternative terms are unlikely to be accepted by the men in the military. Compared to military slangs, unfamiliar Sino-Korean words are, in general, regarded in more need of improvement, which is also more likely to be accepted. The result also implies that the following should be considered in establishing an education method; whether the substitute words have the same meaning as the original words, in what context the words are used, and how the substitute words are formed. In conclusion, this study suggested education method about military slangs and unfamiliar Sino-Korean words used in the military based on the refinement needs and user acceptability.

옥정호로 유입되는 37km의 추령천에는 육봉화된 은어의 이동을 가로막는 많은 보가 설치되어 있었으나 2006년 12월 옥정호 추령천 하류에는 은어가 성숙하기 위해 추령천 상류로 이동하도록 어도가 설치되었다. 따라서 2007년 4월부터 10월까지 13개 지점에서 어도와 은어의 성장률을 조사하였다. 그 결과 어도의 설치 후, 치어들은 강수량이 풍부했던 시기에만 소상할 수 있는 상류를 새로 설치된 어도를 통해서 자유롭게 상류로 이동할 수 있었다. 2007년 9월 산란시기 동안 성숙된 은어는 163±21.5mm로 어도가 설치되기 전인 2006년에 비해 약 13mm, 2004년 약 20mm, 2005년 약 57mm정도 더 크게 나타났다. 따라서 하천에서 어도는 육봉형 은어집단의 평균 크기와 생존력에 중요한 역할을 하는 것으로 확인되었다.

Jeon, Eun-jin. 2012. A linguistic analysis of Slang, which is registered in ‘Youth Slang Dictionary’ in Smart-Phone Application. The Sociolinguistic Journal of Korea 20(1). pp. 267-293. This study analyzed slangs, which are registered in 'Youth Slang Dictionary' in smart-phone application, thereby having aimed to grasp the actual condition of slangs, which are now being used actively. This application is translating through registering slangs, which are used by adolescents, as if Korean dictionary, and is routinely updating, thereby being effective for grasping the actual condition of slangs, which are being lively used in the present age. As a result of analyzing Youth Slang Dictionary, the structural characteristic was indicated most noticeably, which expresses it with the first syllable by clipping a form in a word or word-phrase, given seeing in light of the expression. And sound transcription, Romanizaton, deletion, contraction, alternation, and addition were being indicated. Also, even the phenomenon, which newly expresses by producing new meaning, not the standard meaning of a word, was shown. Examining semantic characteristics, the slangs, which indicate figure, behavior, state, and psychology, were being used much. Each of slangs was strongly indicated the tendency of being used negatively, rather than being used positively.

As a fish way is a structure for fish migrating well toward upper stream due to breaking river flow by a dam or dammed pool, the specific fish's swimming ability is one of the main factors in making a plan and managing it. In addition, it also needs to understand the current field in fish road to evaluate its performance. This study is aimed to analyze the swimming patterns with current velocity changes using a Particle Imaging Velocimetry (PIV) in order to understand the swimming ability of silver fish (Plecoglossus altivelis) that is one of the fishes migrating through the fish way of Nakdong River, and to analyze the 2 dimensional current field near to silver fish at swimming momentum. The results showed that average values of tail beat frequencies for continuous swimming with current velocity were 2.8 Hz at 0.3 m/s, 3.2 Hz at 0.4 m/s, 3.8 Hz at 0.5 m/s, respectively. The wake would be produced by direction turning of fish's tail fin and its magnitude would be verified by the difference of pressure. The pressure turbulent flow produced by its tail beat would be made in both sides, and then, the magnitude of wake should be the source of moving direction. The swimming momentum will help to support the primary factor in making a suitable design for specific fish species migrating toward the district river.

생리적 형질인 수온과 염분에 대한 내성을 양적 형질로 개발하기 위하여 은어의 정상 발생 2배체 (2N-cont),극체형 2배체 (meiotic-G2N), 난할형 2배체 (mitotic-G2N) 및 2종류의 clone (clone-11, clone-15)의 부화 자어를 대상으로 유전적 변이성을 조사했다. 수온은 19. 22.5, 25. 그리고 30.로 설정하였고 각 수온구에 0, 15 및 30의 염분구를 조합하여 12개의 실험구를 만들어 조사했다. 평균

본 연구는 은어의 clone을 생산하여 생리적 형질에 대한 유전적 특성을 조사하고 또 clone의 유전율을 추정했다. 성숙한 완전 동형접합형 자성발생 2배체(난할형 2배체)에서 채란한 후 자성발생을 반복하여 4계통의 clone을 생산하였으며 부화 전부터 같은 수조에 혼합하여 사육하였다. 10개월간 사육한 후 사육수조의 수심을 낮추었을 때의 스트레스가 clone의 혈액성상과 유전율에 미치는 영향에 대해서 조사했다. 생산된 각 계통의 clone은 실험에 사

은어의 자성발생 2배체를 유도하기 위해 자외선에 의한 정자의 유전적 불활성화 및 수정 난의 제 2감수분열과 제 1난할을 저지하기 위한 조건을 검토했다. 정자에 3,000~14,000 erg의 자외선을 조사하였는데 그 결과 3,000 erg를 조사한 시험구에서 89.3%의 높은 생존율을 보였으나 선량이 증가될수록 생존율이 저하했으며 7,000 erg의 자외선을 조사했을 때 생존율이 다시 회복되었다. 따라서 은어의 자성발생 2배체 유도시 정자를 유전적으로
