A Semantic Approach to the Two Locative Markers -ey and -eyse in Korean
박덕수 고려대학교 한국어문교육연구소 2019 한국어문교육 Vol.29 No.-
This paper describes the usage of the two locative case markers -ey and -eyse in Korean. Although other functions -ey and -eyse (i.e. directional meanings of ‘to’ and ‘from’, respectively) are briefly touched on, this paper deals mainly with the so-called locative at rest, which can be translated ‘in’, ‘at’, or ‘on’. Even though there are a few linguistic analyses on the topic, the lack of an adequate pedagogical grammar has left both teachers and learners of Korean as a foreign language with a dilemma. The main purpose of this paper is to present a comprehensive analysis of these two locative particles in Korean in the hope that it may fill the gap between linguistic description and its pedagogical use. After a brief survey of previous studies on the topic, the paper deals with apparent counterexamples to the oversimplified rule based on the dichotomy of predicates (i.e. action vs. non-action predicates), which often appears in Korean language textbooks. This paper shows that in determining the correct usage of these two locatives, in addition to the predicate dichotomy, much more morpho-syntactic, semantic, and pragmatic factors need to be considered.

북미지역에서 본격적인 셰일가스 개발이 이뤄지면서 가격경쟁력과 친환경성을 강점으로 에너지 및 석유화학 산업에 큰 변화를 가져오고 있다. 석유화학 산업에 있어서 가스를 원료로 하는 PDH plant가 신설되거나 기존 크래커에 가스를 원료로 도입하려는 시도가 이뤄지고 있다. 본 발표에서 LPG 산업의 현황 및 전망을 공유하고, 가스화학 공정 중 대표적인 PDH 공정에 대하여 소개하고자 한다.

Horseradish peroxidase가 변성된 탄소복합 바이오센서 개발 및 전기화학적 H<sub>2</sub>O<sub>2</sub>분석
박덕수,Park, Deog-Su 대한화학회 2012 대한화학회지 Vol.56 No.5
Horseradish peroxidase (HRP), alkoxysilane인 TEOS의 겔 용액과 graphite를 혼합하여, 전기전도성을 나타내고 재사용이 가능하며 안정성을 향상시킨 carbon composite electrodes (CCEs) 바이오센서를 제작하였다. TEOS의 졸-겔 전이반응을 이용하여 HRP를 silicate gel network포획시킨 바이오센서는 -0.2 V에서 $H_2O_2$의 환원이 시작되었으며, HRP의 함량과 pH를 변화시켜 최적 분석 조건을 구하였다. 분석 최적 조건에서 검량선 및 검출한계를 구한 결과, 0.2~2.2 mM의 $H_2O_2$ 농도 범위에서 직선적인 감응을 나타내며 검출한계는 0.035 mM이었다. ascorbic acid, acetaminophene, uric acid의 방해작용을 조사한 결과 $H_2O_2$의 전기화학적 분석에 영향을 주지 않았다. A sol-gel derived carbon composite electrodes (CCEs) were fabricated by mixing horseradish peroxidase (HRP), sol of tetraethoxysilane (TESO), and graphite powder. The HRP solution was added to the sol solution of TEOS, and then graphite powder was added to this mixture. The resulting carbon ceramic network effectively encapsulated HRP and shows a catalytic reduction starting at -0.2 V for $H_2O_2$. The optimum conditions for $H_2O_2$determination have been characterized with respect to the enzyme loading ratio and pH. The linear range and detection limit of $H_2O_2$ detection were from 0.2 mM to 2.2 mM and 0.035 mM, respectively. The common electroactive interferences such as ascorbic acid, acetaminophene, and uric acid were not affected upon the response to $H_2O_2$ at the HRP biosensor due to low detection potential.

박덕수 광주보건대학 2004 論文集 Vol.29 No.-
It can be said that it is very important to study Plato's educational thought for understanding the western educational theory. To examine Plato's educational theory, it is also a significant matter to look into how Plato understood the nature of education and what he thought was the purpose of education. I think it a prerequisite to grasp the backgrounds of his educational philosophy in order to understand Plato's educational theory systematically and synthetically. In this point of view, this study examines not only what are the characteristics of Plato's theory of soul, theory of justice and epistemology but also what meanings they have respectively. According to Plato, there are three parts of soul; reason, spirit, and desire. When those play a role individually and are harmonized at the same time, both the ideal of human beings and the purpose of education are achieved. To do so, it is essential to restrict one's desire and do the will with the condition of rational judgement. Those should be righteous, who do not see only the phenomenal world but have cognitive faculty to grasp what the essence of reality is. This philosophy of Plato's is judged to be the starting point of his educational theory. In conclusion, it can be thought to be an important clue for understanding Plato's educational theory to examine into the righteous relationships between soul and body, justice of an individual and a state, and everlasting truth beyond perceiving the phenomenon sensibly.

셰일가스 혁명 이후 기존 Crude 계통 원료 외 가스 원료의 가격 경쟁력이 높아지면서, 세계적으로 기존 납사크래커 중심의 석유화학 공정에서 가스화학 융합공정으로의 재편이 일어나고 있다. 특히 석유화학의 기초유분인 올레핀 공정은 최근 개발된 신기술에 의해 매우 다양한 원료로부터 생산될 수 있기 때문에, 셰일 혁명과 맞물려 지역마다 원료경제성에 적합한 기술을 적용하는 것이 매우 중요하다. 본 연구에서는 다양한 원료에 따라 제품선택성을 조절할 수 있는 신기술이 융합된 사업모델을 개발하였고, 신기술 특성에 따른 경제적 장점을 살펴보았다.

A 54-year-old man presented with primary position upbeat nystagmus andwall-eyed bilateral internuclear ophthalmoplegia. He also showed bilateral limbataxia and impaired horizontal gaze. Upbeat nystagmus obeyed Alexander’s lawand attenuated by visual fixation and disappeared by convergence. Brain magneticresonance imaging showed acute infarction in the bilateral paramedian midbraininvolving the crossing of brachium conjunctivum. Multiple mechanisms includingthe interruption of central vestibulo-ocular projections from anterior canal maybe postulated in upbeat nystagmus of this patient.
