        • 英語 NEXUS에 關한 硏究

          鄭錫頀 漢陽大學校 敎育大學院 1988 敎育論叢 Vol.5 No.-

          The purpose of this study is to explain 'Nexus' which is Jespersen's important grammatical concept and to help promote a better comprehension of the English structure on the part of its learners. The term 'Nexus' may be defined as a construction, between a subject and a predicative, or between a subject part and a predication. By introducing the grammatical concept of Nexus, Jespersen attempts to account for the generative processes of sentence construction and to point out the difference between the 'notional' (underlying) structure and the grammatical (surface) structure of a sentence. For example, Jespersen (l924:122, 1969:42) claims that the underlying relation between the cage and empty in the sentence I found the cage empty is the nexus the cage was empty, and thus the sentence should be analyzed S V 0 (S₂P). The complement the cage empty in the structure I found the cage empty consists of a subject, a verb, and a predicative as the equivalent of a sentence the cage was empty. The complement also has the implicit underlying structure which has a subject as a primary and predicative as a secondary. The term 'junction' is a combination of wards which represents a joining of two elements or a joining of more than two elements. A junction is distinguished in three 'ranks'. In a junction terribly cold weather, terribly is a 'tertiary' as its function to restrict the secondary cold, and cold is a 'secondary' as its function to specity the 'primary' weather. Therefore, in a junction the secondary elements (adjuncts) are joined to a primary word as labels or distinguishing mark. Jespersen (l958:97) maintains that as regards terminology the terms 'primary', 'secondary', and 'tertiary' are applicable to nexus as well as to junction. It is also useful to use the special terms 'adjunct' for a secondary word in a junction, and 'adnex' for a secondary word in a nexus. For tertiary we may use the term 'subjunct'. The difference between nexus and junction can be shown by way of comparison : a nexus is like a drama in which we get life and movement, while a junction is like a solid state of a brick wall. The dog furiously barks. (Nexus) The furiously barking do. (Junction) The concept of nexus seems to explain grammar more easily than any other approach. That is the reason why I have strongly been encouraged to study it.

          윤리교육의 효과성이 교육만족도와 윤리실천의식에 미치는 영향: A사 사례를 중심으로

          정석호,정유진,윤방섭,이주헌 한국경영교육학회 2010 경영교육연구 Vol.62 No.-

          오늘날 국내외적으로 윤리가 기업과 사회의 경쟁력의 원천으로 주목을 받고 있다. 하지만, 국내 기업들은 윤리를 단순히 기업홍보를 위한 마케팅적 시각에서 접근하거나, 윤리강령이나 제도를 만드는 수준에 머무르고 있으며 전 사원이 공감하고 실천하기 위한 체계적이고 효과적인 윤리교육은 아직 미흡한 실정이다. 본 연구에서는 최근 3년 이내에 윤리교육을 받은 경험이 있는 A사 직원들을 대상으로 윤리교육의 필요성인식, 교육체계와 내용이해가 윤리교육만족도와 윤리실천의식 제고에 어떻게 영향을 미치는가에 대해 조사, 분석하였다. 또한 현행 윤리교육의 문제점을 살펴보고 앞으로 효과적인 교육이 되기 위해 추진해야 할 윤리교육의 내용과 방법도 설문을 통해 살펴보았다. 연구를 통해 밝혀진 시사점은 다음과 같다. 첫째, 윤리경영에 대한 전반적인 이해와 공감대 형성을 위해 윤리교육을 체계적으로 정립해 나갈 필요성이 있다. 둘째, 공급자 중심에서 수요자 중심으로 교육체계를 재정립해 나가야 할 것으로 조사되었으며, 천편일률적인 내용의 양적교육에서 탈피하여 조직대상별, 직급(계층)별로 차별화되고 전문화된 양질의 교육이 필요한 것으로 조사되었다. 셋째, 윤리교육의 만족도가 기업 내에서 윤리실천의식에 유의한 영향을 주는 것으로 분석함으로써 향후 윤리교육의 필요성 인식, 교육체계와 내용이해 등 윤리교육 전반에 관한 심도 있는 연구와 주기적인 모니터링을 통해 정책적 제도수립을 강조하였다. Business ethics has been one of the key ingredients for global success. For further economic developments, we should develop well-prepared business ethics education programs. However, existing ethics researches in Korea can not meet the current demands of industries. In this paper, we explore the effect of ethics education on the overall education satisfaction and ethical awareness of employees. A survey research was conducted to the employees of a private company who had been educated at least once for the past 3 years. The major findings of our research are as follows. First, systematic ethics education is crucial for ethical decision making and awareness among employees. Second, teaching contents should closely reflect current industry practices and company policies. Third, systematic and effective ethics education to employees helps companies themselves to promote ethical activities. We expect that this research is conducive to the practical education of business ethics and the promotion of ethics awareness among employees, which can subsequently lead to ethical business activities.

          Ovarian Cancer Prognostic Prediction Model Using RNA Sequencing Data

          정석호,목리디아,송용상,안태진,박태성 한국유전체학회 2018 Genomics & informatics Vol.16 No.4

          Ovarian cancer is one of the leading causes of cancer-related deaths in gynecologic malignancies. Over 70 % of ovarian cancer cases are high-grade serous ovarian cancers (HGSC) and have high death rates due to their resistance to chemotherapy. Despite advances in surgical and pharmaceutical therapies, overall survival rates are not good and accurate prediction of prognosis is not easy because of the highly heterogeneous nature of ovarian cancer. To improve patient’s prognosis through proper treatment, we present a prognostic prediction model by integrating the high dimensional RNA sequencing data with their clinical data through the following steps: (1) gene filtration, (2) pre-screening, (3) gene marker selection (4) integrated study of selected gene markers and prediction model building. These steps of the prognostic prediction model can be applied to other types of cancer besides ovarian cancer.

          Separation of soil Organic Debris using Sucrose-ZnCl2 Density Gradient Centrifugation

          정석호,정덕영,한광현 한국토양비료학회 2012 한국토양비료학회지 Vol.45 No.1

          The active fraction of soil organic matter, which includes organic debris and light organic fraction, plays a major role in nutrient cycling. In addition, particulate organic matter is a valuable index of labile soil organic matter and can reflect differences in various soil behaviors. Since soil organic matter bound to soil mineral particles has its density lower than soil minerals, we partitioned soil organic matter into debris (< 1.5 g cm-3),light fraction (1.5-2.0 g cm-3), and heavy fraction (> 2.0 g cm-3), based on high density ZnCl2- sucrose solutions. Generally, partitioned organic bands were clearly separated, demonstrating that the ZnCl2- sucrose solutions are useful for such a density gradient centrifugation. The available gradient ranges from 1.2 to 2.0 g cm-3. Although there was not a statistically meaningful difference in organic debris and organomineral fractions among the examined soils, there was a general trend that a higher content of organic debris resulted in a higher proportion of light organomineral fraction. In addition, high clay content was associated with increased fraction of light organomineals. Partitioning of soil organic carbon revealed that carbon content is reduced in the heavy fraction than in the light fraction, reflecting that the light fraction contains more fresh and abundant carbon than the passive resistant fraction. It was also found that carbon contents in the overall organic matter, debris, light fraction, and heavy fractions may differ considerably in response to different farming practices.

          Influences of fuel additives on the low temperature reaction of DME HCCI engine

          정석호,이시다 마사히로 한국동력기계공학회 2012 한국동력기계공학회지 Vol.16 No.6

          DME HCCI기관의 단점은 디젤 엔진에 비해 기관부하 영역이 굉장히 좁다는 것이고 이는 저온산화반응이 너무 빨리 일어나서 노크를 발생시키기 때문이다. 저온산화반응을 억제하기 위해서 DME 연소에 미치는 천연가스의 영향을 실험한 결과, 천연가스가 DME의 저온산화반응을 억제시키기 때문에 기관부하영역이 확대된다는 것을 알았다. 본 연구에서는 서로 다른 세탄가를 가진 첨가연료가 DME 저온산화반응에 미치는 영향을 실험적으로 조사하였다. 그 결과 저온산화반응의 최고 열발생율은 세탄가에 의존하지 않지만 착화온도는 세탄가에 의존한다는 사실을 밝혔다.
