This paper is proposed artificial intelligent control based on the vector controlled induction motor drive system. The hybrid combination of fuzzy control and neural network will produce a powerful representation flexibility and numerical processing capability. Also, this paper is proposed control and estimation of speed of induction motor using fuzzy and neural network. The back propagation neural network technique is used to provide a real time adaptive estimation of the motor speed. The error between the desired state variable and the actual one is back-propagated to adjust the rotor speed, so that the actual state variable will coincide with the desired one. The back propagation mechanism is easy to derive and the estimated speed tracks precisely the actual motor speed. This paper is proposed the experimental results to verity the effectiveness of the new method.

윤동주 시의 ‘부끄러움’과 ‘보편지향성’ - 제도적 형식 앞에서의 시적(詩的) 윤리

고명재 ( Ko Myeong-jae ) 한국문학연구학회 2018 현대문학의 연구 Vol.0 No.66

윤동주 시에 나타나는 ‘부끄러움’과 ‘보편지향성’은 그가 현실과 직접적인 관계를 맺으면서 모색했던 시적 윤리의 구체적 결정(結晶)이다. 특히 그의 시에 나타나는 부끄러움은 기존에 반복적으로 활용되어온 ‘부끄러움-성찰’이라는 평면적인 구조로는 온전히 파악될 수 없다. 그의 시에 나타나는 부끄러움은 피해자가 동시대의 피해자들을 보며 느끼게 되는 감정이다. 가해자가 느껴야 할 부끄러움을 오히려 피해자가 고백하는 형국이기에 우리는 관습적으로 이해해온 윤동주 시의 부끄러움을 또 다른 관점에서 접근해볼 필요가 있다. 이러한 맥락에서 그의 시에서 부끄러움이 본격적으로 나타나는 시기가 정확히 전시체제로의 체제 개편이 이루어진 시기(1937년 중일전쟁 이후)와 일치한다는 점은 주목된다. 윤동주 시에 나타나는 부끄러움은 국가 권력에 의해 폭압적으로 파괴되는 생명(삶)의 반응적 감정이었다. 이는 단순히 스스로의 결점을 마주하는 개인적 성찰의 개념을 넘어, 파괴되는 생(生) 앞에서 피해자가 느끼는 존재론적 감정이었다. 그는 이러한 감정인 부끄러움을 통해 우리의 ‘삶-생명’이 언어적· 형식적 제도에 의해 철저하게 분절되고 파괴되고 있음을 드러내고자 했다. 여기서 더 나아가 그는 대문자 제도의 질서와 국가적 형식을 무화시키고자 했다. 바로 그 언어적 대응이 그의 시에 나타나는 보편지향성이다. 윤동주는 끊임없이 생명을 시화(詩化)함으로써, 제도나 언어가 분절하고 해체할 수 없는 생명의 의미를 확보하려 했다. 즉 국가가 언어·합리·측량·기호·법 등의 언어적 제도를 통해 생명을 ‘표준화’ 할 때, 그는 질서와 가치를 무화시키는 생명의 ‘보편화’ 작업으로 체제의 질서에 대응했다. 이 과정에서 그의 시에는 감정이라는 비합리적인 영역의 능력이 적극적으로 활용되고, 생명을 향한 보편적 사랑이 나타난다. 이러한 맥락에서 윤동주 시에 나타나는 ‘부끄러움’과 ‘존재적 보편(생명)을 향한 지향성’은 강력한 국가적 폭력 앞에서 주체가 행할 수 있는 언어적·윤리적 대응이었다. The 'shame' and 'universalism-orientation' shown in the poems by Yoon, Dong-Ju are the concrete crystal of poetic ethics that he sought for in the direct relation with the reality. Especially, the shame shown in his poems cannot be fully understood in the flat structure of 'shame-introspection' that used to be repetitively used. The shame shown in his poems is the emotion felt by victims when seeing the victims of the same age. As the shame that should be felt by assailants is confessed by victims, it would be necessary to approach the shame in the poems by Yoon, Dong-Ju that used to be understood conventionally, in the different perspective. Under this context, we should pay attention to the fact that the period when the shame was fully shown in his poems accurately accords with the period(after the Sino-Japanese War in 1937) of system reform to the war basis. The shame shown in the poems by Yoon, Dong-Ju was the reactive emotion of life(living) which was forcibly destroyed by the state power. Exceeding the concept of personal introspection simply facing one's own flaws, it was the ontological emotion felt by victims in front of the destroyed life. Through this emotion of shame, he aimed to reveal that our 'living-life' was thoroughly segmentalized and destroyed by the linguistic/formative system. Furthermore, he aimed to eliminate the order of capital system and national form. The linguistic action is the universalism-orientation shown in his poems. By continuously treating life poetically, Yoon, Dong-Ju aimed to secure the meanings of life that could not be segmentalized or dismantled by system or language. In other words, when the state 'standardized' the life through the linguistic system such as language/rationality/ measurement/symbol/law, he responded to the order of system with the 'universalization' of life that could eliminate the order and value. In this process, his poems actively use the ability of irrational area such as emotion, and the universal love for life is shown. Under this context, the 'shame' and 'ontological universalism(life)-orientation' shown in the poems by Yoon, Dong-Ju were the linguistic/ethical action that could be performed by a subject in front of strong national violence.

김수영의 시에서 `형식`의 의미와 지향

고명재(Ko, Myeong-jae),김문주(Kim, Mun-joo) 국어교육학회 2016 국어교육연구 Vol.60 No.-

This paper examines works by Kim Soo-young from the perspective of “form” and studies the orientation of form and its relationship with “content.” By doing so, this paper intends to prove that for Kim Soo-young, “form” means “ethical form.” Form has two different meanings to Kim Soo-young. First, form is “place of langue” where detailed aspects of life and problems are described. Thus, the poet tried to reveal and reproduce life by choosing and adopting specific nouns that were widely used in a daily life. Second, form is operation of language with which individual beings show differences. His choice and development of unique nouns which can be called “vacuum language” is a way to maximize mobility of language. In addition, repetition is a method that clearly demonstrates the poet’s concept of form. Through repetition, he showed various differences and acquired aesthetic novelty. Here, repetition does not mean repeating the same meaning of signifiers but exploring the potential of predicates by eradicating central and fixed meaning in sentences. That is, by repetition, the fixed meaning of a subject or a common noun was weakened while differences of exsistents and temporary phases were vividly expressed by predicates. Likewise, repetition is a formative way to narrate the real meaning and value of existents. In this regard, his poets have a ethical form that horizontally depicts the value of all existents. Kim Soo-young strived to figure out how “form” itself can include and reveal “content.” His poets display “content” through form. It is in line with his theory of poetry, so-called theory of the whole body and above all, his works are precious examples of “practices of literature,” which resisted to totalitarianism and standardization.

오규원 후기시의 윤리적 가능성 - 시적 방법으로서의 잠재태와 경계 영역을 중심으로

고명재(Ko, Myeong-Jae) 한국시학회 2021 한국시학연구 Vol.- No.67

본 연구는 오규원의 후기시에 나타나는 윤리적 가능성을 살펴보고자 했다. 이는 시론을 중심으로 연구되어 온 오규원의 후기시를 좀 더 확장적으로 읽기 위함이다. 오규원의 후기시에 나타나는 자연물과 대상은 단순히 미학적인 대상이나 자연적 풍경이 아니라 존재의 역량을 표출하고 있는 능동적인 대상이다. 시인은 이들의 존재성에 가해지는 언어적 · 개념적 폭력성을 최소화하고 이들의 역량을 최대치로 발현할 수 있는 시적 방법을 모색하였다. 본 연구는 이를 다양한 ‘형식적 방법’과 ‘시 작법’을 통해 살펴보았다. 이와 관련하여 첫째, 오규원은 ‘비식별역’과도 같은 규정되지 않는 존재 및 대상들을 적극적으로 형상화했다. 이를 통해 그의 시는 ‘정(定)하지 않는’ 존재의 자유로운 양태를 보여주었다. 그는 특정한 기준이나 개념에 따라 세계를 재편하는 과정이 허구적이고 임의적이라는 것을 ‘경계의 시 쓰기’를 통해 보여주었다. 이 과정에서 열거, 비교, 반복, 대조 등의 다양한 시작법이 활용되었으며 더 나아가 각각의 시-텍스트를 분리하고 결합시키는 ‘집합과 개체화의 시 형식’을 활용하기도 했다. 둘째, 여기서 더 나아가 오규원은 더욱 적극적인 방법으로 ‘잠재태와 비잠재태’를 형상화하는 시적 방법을 모색하였다. 이는 ‘~하지 않는’과 같은 부정형의 진술을 통해 존재의 다양한 역량과 가능성을 확보하는 시적 방법이다. 이를 통해 오규원은 ‘전(全)적으로 있는’는 세계를 형상화하고 다양한 존재의 의미와 역량을 보존할 수 있었다. 이러한 그의 후기시 작업은 매우 윤리적인 가능성을 내포하고 있으며 더 나아가 미학적 정치성의 한 가능성으로도 확장시킬 수 있다. This study explored the ethical potential of Oh Gyu-won’s later poetry. This was to further expand Oh Gyu-won’s later poetry, which has been studied mainly on poetic theories. Natural objects and objects appearing in Oh Gyu-won’s later poems are not merely aesthetic objects or natural landscapes, but active objects expressing the power of existence. He sought a poetic way to minimize the logical and conceptual violence on their existence and to maximize their capabilities. This study inspects at this through various ‘formal methods’ and ‘how to write poetry’. In this regard, first, Gyu-won Oh actively embodied undefined beings and objects such as ‘zones of indistinction’. Through this, his poetry showed the free mode of being ‘undefined’. He showed that the process of reorganizing the world according to specific standard or concepts is fictional and arbitrary through ‘Writing Poetry of Boundary’. In this process, various how to write poetry such as enumeration, comparison, repetition, and contrast were used. And The ‘poetry form of aggregation and individuation’ was used to separate and combine each poem-text. Second, going further than this, Oh Gyu-won sought a poetic method that embodies ‘potential and non-potential’ in a more positive way. This is a poetic method of taking various capacities and possibilities of existence through negative statements such as ‘don’t~ / doesn’t’. Through this, Kyu-Won Oh was able to shape ‘the world that exists intact’ and preserve the meaning and capabilities of various beings. His late poetry works contain very ethical possibilities, and can further expand into one possibility of aesthetic politicity.

Appearance patterns of freshwater fish were investigated in the western Demilitarized Zone (DMZ) adjacent areas near Imjin River in Gyeonggi-do, Korea, of 2014. A total of 61 species belonging to 14 families were found in the river during the survey. The dominant and subdominant species were Zacco platypus (Relative abundance, 20.3%) and Zacco koreanus (12.6%), respectively. Other abundant species include Rhinogobius brunneus (9.2%), Pungtungia herzi (4.4%), Acheilognathus yamatsutae (4.4%), and Pseudogobio esocinus (4.0%). Among the residing species, 24 species (39.3%) were endemic to Korea; and 1 species, Carassius cuvieri, was non-indigenous species. Hemibarbus mylodon is a natural monument, and Lethenteron reissneri, Acheilognathus signifer, Pseudopungtungia tenuicorpa, Gobiobotia brevibarba, G. macrocephala, and G. naktongensis are endangered species in Korea. In addition, Anguilla japonica and Plecoglossus altivelis are catadromous and amphidromous species, respectively. Among the investigated sites, the lower part of Sami Stream (St. 5, 6) and Gunnarm-dam region (St. 11, 14) are particularly valuable for the conservation of species diversity, because many fish species (33~42 species) including a natural monument and several endangered species inhabit in these regions.

Background: Gout is a recurrent infi ammatory arthritis caused by monosodium urate, which can be prevented urate-lowering agents such as allopurinol. However, gout attack can still recur during urate-lowering therapy. In this study we investigated the risk factors associated with recurrence of gout attacks during allopurinol treatment. Methods: A total of 527 gout patients were enrolled, who took allopurinol at least for 6 months at Seoul National University Hospital between March 2001 and March 2013. The patients were divided into those who have ever experienced recurrence of gout attack (recurrence group) and those who haven`t (non-recurrence group) during allopurinol treatment. To reveal the risk factors for gout recurrence, we compared baseline characteristics, concomitant diseases, uric acid level, creatinine level, presence of tophi and type of prophylaxis. Results: The mean age of the enrolled patients was 58.7 years and 96.2% were male. The patients were followed-up for mean duration of 3.17 years. During urate-lowering therapy, 323 patients (61.3%) experienced recurrence of gout attack. In recurrence group, baseline uric acid level was signifi cantly higher than non-recurrence group (8.6 2.0 vs 8.1 1.9 mg/dL, p=0.0043). The presence of tophi was more commonly observed in recurrence group, too (29.4% vs 18.6%, p=0.006). The other variables showed no difference between two groups, which include age, sex, concomitant diseases, the presence of urinary stone, the type of prophylaxis treatment and initial creatinine level. In multivariate logistic regression analysis, high uric acid level (>8.5mg/dl) and the presence of tophi were found to be risk factors for gout attack during allopurinol treatment. Conclusion: Our study revealed that patients who show uric acid level > 8.5 mg/ dL and/or tophi at baseline have higher risk for recurrence of gout attack during allopurinol treatment. Education and closer follow-up will be required for those risky patients.
