This article deals with the problem of buzzwords in translation practice and the education of translation . Buzzwords are words or phrases used by many throughout a relatively short period of time, but in the days of the Internet, these buzzwords trends to spring up faster, and die out faster. First of all, I look at the problem in translating these buzzwords and new words in the digital era. Secondly, among five sub-competences presented by PACTE, I suggested some are more important and critical to the education to improve the ability to properly translate buzzwords. Lastly, I propose that we need long-term and systematic preparation as well as sporadic efforts to translate buzzwords correctly. Creating a database of buzzwords will be very helpful and necessary. The database shall include not only the exact meaning and context of the buzzword, but also the time when the specific buzzword was created, mostly used, and ceased to be fashionable.

global financial crisis. Furthermore, it tests how the impact changes by the phase of the cycle. Design/methodology/approach - This study collected dataset from Barclays Global Aggregate Bond Index through the Bloomberg. It conducted multi-regression analysis by projecting business cycle using Hodrick-Prescott filtering and various cyclical variables, while ran dynamic analysis of 5-variable Vector Error Correction Model to confirm the robustness of the test. Findings - First, it proves to be statistically significant that corporate credit spreads have moved countercyclicaly since the crisis. Second, It indicates that the corporate credit spread’s countercyclicality to the macroeconomic changes works symmetrically by the phase of the cycle. Third, the VECM supports that business cycle’s impact on the spreads maintains more sustainably than other explanatory variable does in the model. Research implications or Originality - It becomes more appealing to accurately measure the real economic impact on corporate credit spreads as the interaction between credit and business cycle deepens. The economic impact on the spreads works symmetrically by boom and bust, which implies that the market stress could impact as another negative driver during the bust. Finally, the business cycle’s sustainable impact on the spreads supports the fact that the economic recovery is the key driver for the resilience of credit cycle.

As the depletion of forests became more widespread due to the increase in the number of roads, the research was conducted on the relationship between temperature and humidity in the forests, assuming that the forests around the roads were affected. Through the forest monitoring, the temperature and humidity of coniferous forests and broadleaf forests in Sedong and Gongju areas were observed at three point of 10m, 20m and 30m from the road boundary to the inside of the forest, respectively. In Yeongdong area, for more reliable results, it was observed from the point of 0m, 10m, and 20m. During the study period, so it was expected the change in tree growth was small, the change of temperature and humidity inside the forest by the road was compared with the temperature and humidity from the road to the inside of the forest from September 2017 to January 2018, the changes of temperature and humidity inside the forest due to linear development such as roads were quantitatively analyzed. Using the HOBO data logger (MX2301, Onset Corp.), the temperature and humidity changes of each site were measured, and the average of the changes have been analyzed monthly. In the case of Gongju coniferous forests in September 2017, the average weekly temperature is 0.57 °C higher than the forest outside from the forest boundary and 1.23 °C higher than the inside of the forest, at night in November 2017, in Sedong broadleaf forests. That is, the ability to control the temperature and humidity of the forests along the road was larger and less variable as the distance from the road boundary to the inside of the forest increased. In this study, it is considered that the high degree of change in temperature and humidity of the forest and the surrounding area due to artificial linear development such as roads will affect the growth of trees. This results could serve as a basis for studying the quantitative scope of linear development affecting forest growth and for managing forest change caused by linear development. 도로 증가로 산림파편화 현상이 심화됨에 따라 도로 주변의 산림이 영향을 받았을 것이란 가정 하에 도로 거리에 따른 산림 내 온·습도 관계에 대해 연구를 진행하였다. 산림 모니터링을 통해 세동, 공주지역의 침엽수림과 활엽수림에 대해 온·습도를 도로경계에서 산림내부까지 각각 10m, 20m, 30m 총 3개의 지점으로 관찰하였고, 영동 지역은 도로 내부 구조물로 인해 0m, 10m, 20m 3개 지점으로 달리 관찰하였다. 연구기간동안 수목 생장의 변화량이 적다고 판단되어, 도로에 의한 산림 내부의 온습도 변화를2017년도 9월부터 2018년도 1월까지 각 지역 및 성상별로 도로로부터 산림내부까지 일정간격을 기준으로온·습도를 교차, 비교하여 도로 등 선형개발로 인한 산림내부의 온·습도 변화를 정량적으로 분석하였다. 특히, 주야간에 따라 소형기상기록장치(HOBO data logger, MX2301, Onset Corp.)를 이용해 각 지점마다의 온·습도 변화량을 측정하였으며 월별로 평균을 구하여 각 지점 간의 특성을 분석하였다. 2017년 9월 공주 침엽수림의 경우, 평균 주간 온도가 산림경계에서 26.05℃로 25.48℃인 산림외부보다 0.57℃ 높고 24.82℃인 산림내부보다 1.23℃ 높아 산림내부로 들어갈수록 온도가 내려갔다. 야간에는 2017년11월 세동 활엽수림에서 산림경계가 0.04℃, 산림외부는 0.35℃, 산림내부는 0.64℃로 산림 외부에서 산림 내부로 들어갈수록 더 높은 온도를 띄는 것을 확인할 수 있었다. 즉, 도로에 따른 산림의 온·습도 조절능력은 도로경계에서 산림 내부로 거리가 멀어질수록 크고 변동성이 적었으며 산림 내부 성상에서는 침엽수에서 온·습도 조절 능력이 더 큼이 확인되었다. 본 연구를 통해 도로 등 인위적 선형개발에 따른 산림 및주변 지역의 온·습도의 높은 변화량을 야기해, 수목 생장에 영향이 있을 것으로 판단된다. 본 연구는 산림생장의 영향을 미치는 선형개발의 정량적 범위를 파악하기 위한 연구 및 선형 개발 시 야기되는 산림 변화의 관리를 위한 토대가 될 것이다.

NUMA 시스템에 최적화된 병렬 해시 테이블

최재용,정내훈 한국게임학회 2020 한국게임학회 논문지 Vol.20 No.5

In MMO game servers, NUMA (Non-Uniform Memory Access) architecture is generally used to achieve high performance. Furthermore, such servers normally use hash tables as internal data structure which have constant time complexity for insert, delete, and search operations. In this study, we proposed a concurrent hash table optimized for NUMA system to make MMO game servers improve their performance. We tested our hash table on 4 socket NUMA system, and the hash table shows at most 100% speedup over another high-performance hash table. MMO 게임 서버에서는 성능을 높이기 위해 NUMA(Non-Uniform Memory Access) 구조를 사용해 하드웨어를 구성하는 경우가 많다. 또한 내부 자료구조로 삽입, 삭제와 탐색에 소요되는 시간이 짧은 해시 테이블과 같은 자료구조를 많이 사용한다. 본 논문은 NUMA 구조에 최적화된 해시 테이블을 제안하여, NUMA 시스템을 사용하는 게임 서버의 성능을 더 높일 수 있도록 한다. 제안된 해시 테이블을 4 소켓 NUMA 시스템에서 실험한 결과, 기존의 고성능 해시 테이블에 비해 최대 2배의 성능 향상을 확인할 수 있었다.

최재용 한국스포츠학회 2019 한국스포츠학회지 Vol.17 No.4

The purpose of this study is to investigate the relationship between coach guidance type and performance level analysis recognized by ice skaters using the Rasch model. To this end, a survey was conducted on 50 athletes registered as Seoul athletes among the 168 athletes enrolled in the 2019 Korea Ice Federation. One out of 50 questionnaires were removed due to many missing values. A total of 49 responses were applied to the analysis. The Rasch Rating Scale Model was applied to determine the coaching style perceived by middle and high school ice skaters and the psychological reaction level of performance level. The Rasch Rating Scale Model was applied. ), Although skaters value their performance highly, they can conclude that they are very determined to grow into top athletes through constant effort and self-care. 이 연구는 Rasch 모형을 적용한 빙상선수가 인지하는 코치지도유형 및 경기력 수준 분석의 관계를 규명하는데 목적이 있다. 이를 위해 2019년 대한빙상경기연맹에 등록된 선수 중・고등부 168명 중 서울특별시 선수로 등록된 50명을 대상으로 설문조사를 수행하였다. 50명 중 1명의 설문응답에 결측치가 많아 제거하였고, 총 49명의 응답결과를 분석에 적용하고, 중・고등부 빙상선수가 지각하는 코치지도유형과 경기력 수준의 심리적 반응 수준인 현실 수용도를 판단하기 위하여, Rasch 평정척도모형(Rasch Rating Scale Model)을 적용하였고, 분석 프로그램은 jMetrik 4.05(Meyer, 2016)를 이용하여 다음과 같은 결론을 도출하였다. 빙상선수들은 자신의 경기력을 높게 평가하고 있지만, 꾸준한 노력과 자기관리를 통해 정상권에 속하는 선수로 성장하고자 하는 의지가 매우 강한 것으로 판단이 가능하다는 결론을 얻을 수 있었다.

『나의 할아버지가 탈옥한 이야기』와 <5일의 마중> 비교 연구 - 중국 영화 비평의 재정치화

최재용 중국문화연구학회 2019 중국문화연구 Vol.0 No.46

The study compares and analyzes the movie <Gui lai>(Coming home) with the novel <Lu fan Yanshi>(Lu Yanshi the criminal), and through the comparison I tried to reveal what gets hidden and what gets revealed in the 'translation' process. And ultimately, I wanted to discuss about the limitations and possibilities of the medium of contemporary Chinese cinema. As the novel gets translated into the movie, I believe two important things were either deleted or covered up by the director, Zhang Yimou. The first thing is women. The film excludes or shrinks the role of two main female characters of the novel, Feng Danjue(daughter) and Feng Yifang(Lu's Stepmother), so that Lu Yanshi can be portrayed as the perfect husband, father and patriarch. The second thing I want to talk about is a drastic cut in historic/political content of the novel, and many people have already pointed this out. Compared to novel, the movie is a typical melodrama devoid of any obvious political message. But no matter how Zhang tries to hide the violence of Cultural revolution, some things cannot be completely wiped out. I will call this things 'trace evidence'. These traces sometimes are left out there consciously, sometimes unconsciously. By collecting and analysing these traces and debris, I believe it is possible to politically re-read the text of Chinese cinema. The movie tries to give us the illusion of love and reconciliation, but once we see beyond the cover-ups and face the movie itself, we might be able to find the possibilities to re-politicize the cultural contents of contemporary China.
