■Background Overall prevalence of visual field loss after stroke was estimated at 31%, ranged from 5.5- 57%. Among them, homonymous hemianopia is the most common symptom of post-stroke visual field loss and leads to a decrease in the quality of life and therapeutic effect. However, standard treatment has not been established. ■Case report A 48-year-old male with right side homonymous hemianopia by a left occipital-parietal lobe hemorrhage was treated with Qu-Ji-Du-Huang-Wan, acupuncture and electroacupuncture for 20 days. We used confrontation visual field exam, automated perimetry and visual analog scale for evaluating symptoms. Following treatment, confrontation visual field exam and the subjective discomfort was improved. ■Conclusions The present case report suggests that combined Korean medicine treatment might be an effective treatment of post-stroke homonymous hemianopia. A number of follow up studies should be conducted to clarify the effectiveness of treatment.

유전자알고리즘의 성능향상을 위한 선택적 돌연변이

정성훈,Jung, Sung-Hoon 한국정보처리학회 2010 정보처리학회논문지B Vol.17 No.2

유전자알고리즘의 조숙수렴현상(premature convergence phenomenon)은 유전자알고리즘의 성능을 크게 저하시키기 때문에 이 문제를 해결하는 것이 성능향상에 크게 영향을 준다. 본 논문에서는 유전자알고리즘의 조숙수렴현상을 완화하여 성능을 향상시키기 위한 선택적 돌연변이 방법을 제안한다. 선택적 돌연변이에서는 유전자알고리즘 개체의 등급에 따라서 염색체의 특정영역에 비트를 추가적으로 돌연변이 시킨다. 이렇게 함으로서 등급이 낮은 개체는 표현형 상에서 많은 변화가 일어나고 등급이 높은 개체는 작은 변화가 일어나게 된다. 결국 좋은 개체는 그 주변을 세부적으로 탐색하며 좋지 못한 개체는 새로운 영역을 탐색할 기회가 높아지게 되어 조숙수렴현상을 완화하면서 성능향상을 꾀할 수 있게 된다. 성능향상을 측정하기 위하여 4개의 대표적 함수 최적화 문제에 적용해서 제안한 방법의 성능을 측정하였다. 실험결과 기존의 유전자알고리즘보다 성능이 크게 향상됨을 확인하였다. Since the premature convergence phenomenon of genetic algorithms (GAs) degrades the performances of GAs significantly, solving this problem provides a lot of effects to the performances of GAs. In this paper, we propose a selective mutation method in order to improve the performances of GAs by alleviating this phenomenon. In the selective mutation, individuals are additionally mutated at the specific region according to their ranks. From this selective mutation, individuals with low ranks are changed a lot and those with high ranks are changed small in the phenotype. Finally, some good individuals search around them in detail and the other individuals have more chances to search new areas. This results in enhancing the performances of GAs through alleviating of the premature convergence phenomenon. We measured the performances of our method with four typical function optimization problems. It was found from experiments that our proposed method considerably improved the performances of GAs.

Pseudo MOSFET 기술에 의한 양성자 조사 SOl 웨이퍼의 캐리어 수명 분석

정성훈,이용현,이재성,권영규,배영호,Jung, Sung-Hoon,Lee, Yong-Hyun,Lee, Jae-Sung,Kwon, Young-Kyu,Bae, Young-Ho 한국전기전자재료학회 2009 전기전자재료학회논문지 Vol.22 No.9

Protons are irradiated into SOl wafers under total dose of 100 krad, 500 krad, 1 Mrad and 2 Mrad to analyze the irradiation effect. The electrical properties are analyzed by pseudo MOSFET technology after proton irradiation. The wafers are annealed to stabilize generated defects in a nitrogen atmosphere at $300^{\circ}C$ for 1 hour because proton irradiation induces a lot of unstable defects in the surface silicon film. Both negative and positive turn-on voltages are shifted to negative direction after the irradiation. The more proton total dose, the more turn on voltage shifts. It means that positive oxide trap charge is generated in the buried oxide(BOX). The minority carrier lifetime which is analyzed by the drain current transient characteristics decreases with the increase of proton total dose. The proton irradiation makes crystal defects in the silicon film, and consequently, the crystal defects reduce the carrier lifetime and mobility. As these results, it can be concluded that pseudo MOSFET is a useful technology for the analysis of irradiated SOI wafer.

루만의 사회이론에서 현대성의 한계

정성훈 ( Sung Hoon Jung ) 한국사회역사학회 2013 담론 201 Vol.16 No.3

Luhmann`s theory of society undermines the ground of postmodern discourse by its conception of modernity. It is composed of three theories, which are unfolded through three dimensions of sense: communication media theory on social dimension, evolution theory on temporal dimension, and differentiation theory on fact dimension. This article pays attention to the limits of modernity in three theories and puts up a candidate for fourth dimension. The fourth dimension is the spatial dimension of sense which was even ignored by Luhmann. Therefore, the technological development of electronic media, the difference of inclusion and exclusion, the unsynchronized evolution of function systems, and the emerging sense of space are the limits of modernity.

창조도시와 문화도시에 대한 인문적 비판

정성훈 ( Sung Hoon Jung ) 한국철학사상연구회 2012 시대와 철학 Vol.23 No.1

The purpose of this paper is the humanistic critique of ``creative city`` and ``cultural city``. These two concepts of city have evaluated as alternatives against the concept focussing economy and politics. My humanistic critique is composed by conceptual critique and humane critique. These concepts of city have conceptual ambiguity and the possibility of justifying social exclusion. But I don`t think that these concepts have to be abandoned. Because these concepts imply the paradigm shift of global economy, above all have progressive potential against construction-centered city. Therefore I suggest ``human rights city`` as supplementary concept and on the basis of this suggestion try to find the better alternative city concept.

Recent studies validate the idea that consumer judgment of products can affect consumer purchase intentions. Consumers judge products based on product quality, after sales satisfaction, and other visible values, but consumers also judge products on country-of-origin image, brand image and such intangible values. In this paper, we will examine consumer ethnocentrism and animosity, which are frequently responsible for country-of-origin prejudices, because the offending (i.e. exporting) nation has engaged in economic, political, or even military activities that the consumer finds difficult to forgive. The results of the study show a positive effect of product judgment on consumer purchase intentions, but consumer ethnocentrism and animosity negatively affect product judgment and consumer purchase intentions of foreign products. In the Chinese market, ethnocentric Chinese consumers have negative perceptions of foreign products with negative intentions to buy them. Chinese consumers have strong animosity for Japanese products, which negatively affect product judgments and purchase intentions to buy; therefore, Japanese corporations should increase cooperation with Chinese corporations. Conversely, for Korean companies, product judgment primarily affects consumers` intentions to buy; consequently, Korean companies should improve their product quality, after-sales satisfaction, brand image and other tangible aspects to improve consumer judgment.

1990년대부터 기업의 사회적 책임 (CSR)은 기업과 연구자에게 많은 관심을 끌기 시작했다. 소비자의 구매 행동은 직접적으로 기업의 재무 성과뿐만 아니라 회사의 미래 발전과도 관련이 있다. 많은 CSR에 관한 기존의 연구는 주로 기업의 관점에 초점을 맞추고 있다. 이 논문은 소비자, 기업, 국가 세 가지 측면에서 기업의 사회적 책임이 구매 의도에 미치는 영향을 분석하고자 한다. 본 연구는 중국에 있는 소비자의 구매 의도에 미치는 사회적 책임 활동의 영향을 분석하기 위해 삼성 브랜드를 이용하는 고객 및 이용할 의사가 있는 고객들을 대상으로 모집하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 기업의 사회적 책임 활동이 기업-소비자 동일시에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 기업의 명성과 원산지 이미지에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 또한 기업의 사회적 책임 활동과 구매의도 간의 관계에 대한 조절 변수들 중에 기업-소비자 동일시는 기업의 명성과 원산지 이미지 보다 더 중요한 조절변수로 나타났다. Since the 1990s, Corporate Social Responsibility (CSR) issues have been attracting more and more attention from companies and researchers alike. The purchasing behavior of consumers is directly related to not only a company’s financial performance, but also the future development of the company. Much of the previous research regarding CSR has mainly focused on the perspectives of enterprises. This paper aims to study the impact of CSR on purchase intention in three aspects - consumer, company and country. We decided to use Samsung to describe the impact of CSR on consumer purchase intentions in China. The results of this study revealed that CSR has a positive impact on the consumer-company identification, corporate reputation and country of origin image. Consumer-company identification turned out to be amore important moderator between CSR and consumers’ purchase intentions than country of origin image and corporate reputation.

인간적 사회와의 작별 -니클라스 루만의 사회관을 통한 새로운 사회 비판의 출발점 모색-

정성훈 ( Sung Hoon Jung ) 한국철학사상연구회 2007 시대와 철학 Vol.18 No.2

Mein vorliegender Beitrag ist eine Vorbereitung auf eine neue kritische Theorie der Gesellschaft, die auf die Ideen der menschlichen Gesellschaft verzichtet. Um einen sich nicht auf leere Ideen grundenden Ausgangspunkt zu finden, nehme ich Theorie der sozialen Systeme von Niklas Luhmann auf, die Charakteristik der modernen Gesellschaft und Lage der Menschen wohl zu erklaren scheint. Bei Erklarung uber Emergenz von sozialen Systemen durch Auflosung des Problems der doppelten Kontingenz, bestreitet Luhmann die Behauptungen, daß die Gesellschaft aus den Menschen bestehen. Gesellschaft als umfassendes Sozialsystem ist Kommunikationssystem und Menschen gehoren zur Umwelt der sozialen Systeme. Ferner ist die functional differenzierte moderne Gesellschaft evolutionare Errungenschaften, die gar nicht ahnlich mit der Figur des Menschen sind. Insofern Luhmann auf Indifferenz der enthumanisierend-azentrischen Gesellschaft fur ihre Umwelten (Menschen, Natur) hinweist, haben seine Beschreibungen einen kritischen Aspekt. Luhmanns Kritik ist zwar noch keine praktische Kritik, die alternative Kommunikationen erzeugen kann. Ich denke jedoch, daß Luhmanns Auffasung der Gesellschaft eine der wichtigsten Grundlagen fur Ausgangspunkt einer neuen Gesellschaftskritik ist, weil sie nicht nur besonnene Beobachtungen der modernen Gesellschaft, sondern Verweisung auf Einschrankungen des kritischen Beobachters ermoglicht.

다중 여왕벌 진화를 통한 여왕벌 유전자알고리즘의 성능향상

정성훈(Sung-Hoon Jung) 한국컴퓨터정보학회 2012 한국컴퓨터정보학회논문지 Vol.17 No.4

The queen-bee genetic algorithm that we made by mimicking of the reproduction of queen-bee has considerably improved the performances of genetic algorithm. However, since we used only one queen-bee in the queen-bee genetic algorithm, a problem that individuals of genetic algorithm were driven to one place where the queen-bee existed occurred. This made the performances of the queen-bee genetic algorithm degrade. In order to solve this problem, we introduce a multiple queen-bee evolution method by employing another queen-bee whose fitness is the most significantly increased than its parents as well as the original queen-bee that is the best individual in a generation. This multiple queen-bee evolution makes the probability of falling into local optimum areas decrease and allows the individuals to easily get out of the local optimum areas even if the individuals fall into a local optimum area. This results in increasing the performances of the genetic algorithm. Experimental results with four function optimization problems showed that the performances of the proposed method were better than those of the existing method in the most cases.
