홍승희 한국수학교육학회 1975 수학교육 Vol.13 No.3

거리공간과 Normal countable compact의 位相積이 Normal이라는 것은 A.H. Stone에 의하여 이미 밝혀졌고, V.I. Malyhin은 space expX의 Cardrnal invariant와 공간 X 사이의 관계를 논하였다. 본 논문에서는 V.I. Malyhin이 밝힌 tightness의 개념을 도입하여 countable tightness의 pracompact와 normal strongly countable compact 공간의 topological product가 Normal이라는 것을 증명하였다.

Alcohol Intake and Risk of Thyroid Cancer: A Meta-Analysis of Observational Studies

홍승희,명승권,김현숙 대한암학회 2017 Cancer Research and Treatment Vol.49 No.2

Purpose The purpose of this study was to assess whether alcohol intake is associated with the risk of thyroid cancer by a meta-analysis of observational studies. Materials and Methods We searched PubMed and EMBASE in June of 2015 to locate eligible studies. We included observational studies such as cross-sectional studies, case-control studies, and cohort studies reporting odd ratios (ORs) or relative risk (RRs) with 95% confidence intervals (CIs). Results We included 33 observational studies with two cross-sectional studies, 20 case-controls studies, and 11 cohort studies, which involved a total of 7,725 thyroid cancer patients and 3,113,679 participants without thyroid cancer in the final analysis. In the fixed-effect model meta-analysis of all 33 studies, we found that alcohol intake was consistently associated with a decreased risk of thyroid cancer (OR or RR, 0.74; 95% CI, 0.67 to 0.83; I2=38.6%). In the subgroup meta-analysis by type of study, alcohol intake also decreased the risk of thyroid cancer in both case-control studies (OR, 0.77; 95% CI, 0.65 to 0.92; I2=29.5%; n=20) and cohort studies (RR, 0.70; 95% CI, 0.60 to 0.82; I2=0%; n=11). Moreover, subgroup meta-analyses by type of thyroid cancer, gender, amount of alcohol consumed, and methodological quality of study showed that alcohol intake was significantly associated with a decreased risk of thyroid cancer. Conclusion The current meta-analysis of observational studies found that, unlike most of other types of cancer, alcohol intake decreased the risk of thyroid cancer.

행동경제학 관점에서 바라본 책임원칙의 재구성 제언

홍승희 경북대학교 법학연구원 2019 법학논고 Vol.0 No.65

In criminal law, the principle of responsibility is to understand that human behavior as a crime is regarded as the product of the actor's determination of free will and that the actor should be responsible for choosing illegal act and going to crime do. In other words, even though there is a reasonable reason to choose a lawful act, it means that the legitimacy of punishment is recognized because he can be criticized for illegal choice because he has gone to illegal (crime). This principle of accountability also meets the legitimacy of the exercise of state penalties. However, the principle of responsibility linked with the legitimacy of punishment is challenged by the development of brain science and cognitive science. On the other hand, similar to the principle of liability of the criminal law, there is a discipline that aims to maximize utilities on the premise of human rational decision making. However, the premise of this "human image with a rational reason" proposed in the traditional mainstream economics is criticized mainly by behavioral economics, that is, every moment human beings are not rational and only have "limited rationality". This behavioral economics argument is asserted by discovering anomales of human reason through 'heuristic' and 'biased program'. From the ideal phenomena, the human cognitive system is not only a rational rational system, , It is argued that the state should intervene in a way that induces indirectly rather than directly enforcing the various alternatives for the rational choice of the individual. We can expect to see a new national role by applying the human perception system and rationality assumed in this behavioral economics, and also the new interventionist model of the state to the principle of responsibility of the criminal law. 형법에서 책임원칙은, 범죄로 나아간 인간의 행동을 행위자의 ‘자유의지결정’의 산물로서 파악하여 행위자는 적법한 행동을 선택할 수 있었음에도 그가 불법을 선택하여 범죄로 나아간데 대하여 책임을 져야한다는 것을 의미한다. 이는 다른 말로 적법행위를 선택할 수 있는 합리적 이성이 있음에도 그가 불법(범죄)로 나아갔으므로 이러한 불법선택에 대해서는 ‘비난가능’하므로 형벌부과의 정당성이 인정된다는 것을 의미한다. 이처럼 책임원칙은 국가형벌권행사의 정당성문제와도 맞닿아 있다. 그런데 이처럼 형벌의 정당성문제와 연결되어 있는 책임원칙은 최근 뇌과학 및 인지과학의 발달로 ‘의사자유’의 표상은 도전을 받고 있는 상황이다. 한편 형법의 책임원칙과 유사하게, 인간의 합리적 의사결정을 전제로 하여 효용의 극대화를 창출하고자 하는 학문이 있는데 바로 경제학이다. 그런데 전통적인 주류경제학에서 상정하는 이러한 ‘합리적인 이성을 가진 인간상’이라는 전제는 최근 행동경제학을 중심으로 비판받고 있는데, 즉 매순간 인간은 합리적이지 않으며 다만 ‘제한된 합리성’을 가지고 있을 뿐이어서 때때로 인간은 비합리적 선택으로 나아간다는 것이다. 이러한 행동경제학의 주장은 ‘휴리스틱’과 ‘편향프로그램’을 통해 인간이성의 이상현상들(anomales)을 발견하면서 주장되는 것인데, 이상현상들로부터 인간의 인식체계는 합리적인 이성체계 뿐만 아니라 충동적인 감정체계도 동시에 갖고 있어서 개인이 합리적인 선택을 하도록 국가가 다양한 대안들을 직접적으로 강제하는 방식이 아닌, 간접적으로 유도하는 방식으로 개입할 것이 주장된다. 이러한 행동경제학에서 상정하는 인간의 인식체계와 합리성, 나아가 국가의 새로운 개입주의 모델을 형법의 책임원칙에도 적용함으로써 새로운 국가적 역할을 보여줄 것으로 기대할 수 있다.

열처리된 돌로마이트를 이용한 중금속(Cd2+, Cu2+, Pb2+, Ni2+) 흡착

Calcium-rich dolomite was calcined at high temperature to increase heavy metal removal capacity. Dolomite calcined at 900℃ (D900) was shown to obtain highest adsorption amount of heavy metal (Cd2+, Cu2+, Pb2+, Ni2+). Kinetic, equilibrium, and thermodynamic adsorption was performed to characterize the heavy metal adsorption onto D900. Heavy metals adsorption onto D900 reached equilibrium within 3 hours. The maximum adsorption amounts of Cd2+, Cu2+, and Ni2+ onto D900 were 466.51 mg/g, 566.33 mg/g and 567.84 mg/g, respectively. Freundlich model was more suitable for describing equilibrium adsorption of heavy metals onto D900 than Langmuir model. Thermodynamic analysis showed that the heavy metal adsorption onto D900 is endothermic and spontaneous reaction. The increase of ionic strength of solution influenced negatively on heavy metals (Cd2+, Cu2+, Pb2+, Ni2+) adsorption. As the dosing amount of D900 increased, the removal percentage of Cd2+ and Ni2+ remained constant but the amount of heavy metal adsorption onto unit mass of D900 was decreased. The increase of D900 dose increased the removal percentage of Cu2+ and Pb2+ but decreased its amount of Cu2+ and Pb2+ adsorption onto unit mass of D900. It can be concluded that D900 can be used as an efficient adsorbent for the removal of heavy metals from aqueous solution.

Museum has a purpose of the transfer of knowledge, It is a space that provides exhibition and education of visitors. For the purpose of transmission of museum knowledge, you look the same as schools and libraries, There is a difference between the schools and libraries to pursue the teaching methods of direct transfer. Then, let us see how the knowledge transfer is being performed using the space of the museum. Museum can be distinguished history museums, art galleries, the Museum of Science. The Museum of Art and History Museum, focuses on the theme and order from the exhibition by historicity. In contrast, the Science Museum, the focus of the exhibition have been together on the subject than the order. Thus Science Museum can be a building is intended knowledge transfer through the subject relatively clear, The exhibition is also constructed in the delivery of interest and attention. Therefore, in this study, I'm trying to ensure that the configuration of the exhibition space and a method of transmitting knowledge of the Science Museum indicates the relevance, and to present a strategy for constructing the exhibition space of the Museum of Science. They are as follows: The result through the course of the study as described above. In the exhibition room that is configured in the order, the degree of concentration of the visitors appear high in the interval a high degree of integration. This is consistent theory of Space Syntax. In the exhibition room that is configured on the theme, the degree of concentration of visitors is displayed in the lower section having a low degree of integration. This is displayed on the reverse of the theory of Space Syntax. From this result, In the exhibition space which composed to arrangement thematically, it is possible to inference like these. First, the space which is high degree of integration is playing role in path for people. Second, the space which is low degree of integration is arranging important exhibit dispersely for making people more concentrating on it.
