There are various views in the boundary of deflationism of truth in regarding the nature and role of truth. This paper surveys the issue on how the core thesis uniting the deflationism is characterized. First, I will examine some comments on what is the central thesis supported or rejected by the deflationists and inflationists, mainly discussing Armour-Garb and Beall's work, and will show on which aspects they are unsatisfying. From this, I will suggest these statements: first, the central cores of deflationism are conceptual fundamentality and explanatory exhausting. Second, the particularity thesis, understood in an alternative way, cannot be a central claim of deflationism. Third, another important claim from deflationists, the expression thesis, can be derived from the two main thesis above. But it is still not clear enough what the non-expressive explanatory role of truth, which is denied by the expression thesis. So I will check some possible clarifications on it and discuss why they should be rejected. And I will introduce Dummett's view on the role of truth condition in truth conditional explanation of meaning, and I will claim that if Dummett is right why the role must be a inflated one. Finally, I will suggest a further implication that the understanding on the both sides can be widened by connecting considerations on both views.

Michael Williams, in his paper, rejects the wide-accepted view that Donald Davidson's radical interpretation is a truth conditional account of meaning, and suggests a claim that robust truth in fact does not play any role in Davidson's interpretation and thus interpretation can be in accord with the deflationary theory of truth. In this paper, I will first research the right understanding on the explanatory relations in radical interpretation between truth and meaning, and on that ground, will evaluate the adequacy of Williams' suggestion. My diagnosis is that the acceptability of Williams' idea depends on how we regard the several factors which are crucial for interpretation. Especially I will argue that whether truth condition is regarded as deflationary or inflationary makes difference to the way of understanding radical interpretation, hence the room for taking radical interpretation as deflationary can be in two different ways. Furthermore I will show the same argument can be applied to Williams' another claim that Paul Horwich's use theory of meaning is similar to Davidson's account.

수학 기초의 위기에 대한 직관주의적 대안은 파격적인 것이었다. 수학을 지나치게 축소시켰다고 비난을 받기도 하지만 역리의 제거라는 측면만 본다면 직관주의는 성공적이라고 할 수 있었다. 본고는 직관주의를 개관하고 직관주의가 가지는 보다 철학적이고 본질적인 측면을 직관주의의 창시자인 Brouwer의 수학관과 세계관에서 찾는다.

Four types of experiments were performed to check the similitude of member behavior between prototype and 1 /10 scale models : (1) Test of slender columns with P-$\Delta$ effect, (2) Test of short columns with and without confinement steel, (3) Test of simple beams without stirrups, and (4) 'T-beam test. Based on the results of experiments, the conclusions were made as follows : (1) The P-$\Delta$ effect of slender columns can be almost exactly represented by 1/10 scale model. (2) The effect of confinement on short columns by the hoop steel can be also roughly simulated by 1/10 scale model. (3) The failure modes of simple beams without stirrups are brittle shear failures in prototype whereas those of 1/10 scale models are the ductile yielding of tension steel followed by large diagonal tension cracking and compressive concrete failure. (4) The behaviors of prototype and 1/10 scale model in T-beams appear very similar.

지진하중에 대한 구조물의 동적 거동과 성능을 예측 평가하기 위하여 실험적 방법들이 흔히 사용되고 있으나, 실험장비의 제약과 구조물의 규모 등으로 대부분 축소모형실험에 의존하고 있다. 그러나 일반적인 상사법칙(similitude law)은 탄성범위에서 유도된 것으로 지진거동과 같은 비탄성 거동을 예측하는 경우에는 한계가 있다. 또한 탄성범위 내에서도 크기효과(size offset)가 발생하므로 축소모형의 실험결과를 원형 구조물에 직접 적용하는 것은 많은주의가 필요하다. 본 연구에서는 원형 구조물(prototype)과 축소모형(scaled model)을 모두 실험 대상으로 하여 실제 축소모형만을 실험하여 원형 구조물의 거동을 예측하는 경우의 문제점을 확인하고 그 해결방법을 모색하고자 한다. 실제로 축소모형실험에서는 원형 구조물의 경계조건을 정확히 재현하기 어려우며, 실험모형의 제작과정과 실험과정에서의 모든오차가강성의 변화로 반영되어 나타난다. 따라서 본 연구에서는 기하학적 상사율과 변화된 강성비(stiffness ratio)를 함께 고려하여 고유진동수의 오차를 보정하고 비탄성 거동중에도 직접적인 실험결과의 비교가 가능한 상사법칙을 제안하였다. 더불어 제안된 상사법칙을 적용한 유사동적실험 (pseudodynamic test)을 수행하여 실험오차보정(experimental error compensation)효과를 검증하였다.

The identity theory of truth insists that a truth bearer is identical with a fact. First, I will consider how we can make the thesis intelligible. For this, I classify the identity relation which the identity theory discusses into two kind; trivial and non-trivial relation. And I show that the trivial one is not adequate to be qualified to be applied to the identity theory. The non-trivial relation can be adopted in robust or modest way. I argue that the robust kind of identity theory is incoherent itself. Then, I explain why we should compare the modest identity theory with the deflationism. From this comparing, I will draw the consequence that two choices are left to the modest theory. If they choose one way, there is no reason for us to prefer the identity theory to deflationism. On the other hand, in case that they choose the other way, I argue what kinds of interesting problem is left to be solved by the modest theorists. Finally, I will evaluate the limit and prospect of the result of the problem in case that the identity theorists achieve their goal.

The necessity of a high-rise building in big cities gave a new problem to structural engineers. The shortening effect of vertical members needs special considerstion in the desigh and construction of high-rise buildings. The shortening of each column transfers load to nonstructural members such as partitions, cladding, and M/E systems which are not designed to carry gravity loads. Also, the slabs and beams will tilt due to the cumulative differential shortening of adjacent vertical members. The main purpose of estimating the total shortening of vertical structural members is to compensate the differential shortening between adjacent members. This paper presents the structural effect of differential shortening between in main structural members. Lateral earthquake load is applied to the 52 story concrete structure which has an initial vertical displacement due to the gravity load. Shortening amount for each vertical member was estimated using the computerized column shortening software. Comparison of stresses between the shortening corrected structure and the uncorrecated structure due to earthquake load was discussed.

국가와 시민의 관계에서 볼 때, 기존의 정치·경제·행정체제 및 운용의 모습은 많은 문제점을 드러내고 있다. 정치적으로 간접(의회)민주주의 제도는 국민참여의 축소, 공공의제 및 영역의 축소, 사회적 불평등의 심화 및 정치불신을 초래하였으며, 경제적으로 시장경제의 실패는 정부개입과 그에 따른 정부의 실패를 야기하였다(정정목, 2000). 또한 행정 부분에서는 삼권분립의 견제와 균형보다는 행정권의 강화에 따른 이른바 행정국가의 등장과 이에 따른 국민의 저항과 입법 및 사법부의 위축 등을 경험하였다. (중략)

IDF 곡선은 수리구조물의 설계에 이용되며 본 연구에서는 기후변화를 고려한 GCM의 시간적 공간적 축소화기법을 통하여 미래의 IDF 곡선을 생성하였다. GCM자료로는 HadCM3과 CGCM3의 지역주의와 경제발전을 지향하는 A2시나리오를 이용하였다. GCM자료에 대한 공간적인 축소화기법으로 다중회귀 모형인 SDSM(Statistical DownScaling Model)을 이용하여 2030년, 2050년, 2080년의 미래의 일강우 자료를 생성하였다. 이를 다시 시간적 축소화기법인 GEV분포를 이용한 Scaling-Invariance기법을 적용하여 시단위의 강우자료를 생성하였다. 이를 통해 최종적으로 HadCM3과 CGCM3에 대한 각각 미래의 IDF곡선을 생성하였다. CGCM3의 경우 지속적인 강우강도의 증가를 보였지만 HadCM3의 경우 2050년대 감소하다 2080년대 다시 증가하는 양상을 보였다. 또한 CGCM3의 경우 HadCM3의 경우보다 좀 더 높은 강우 강도를 보였다. 본 연구의 대상지역은 서울지역이며 생성된 자료의 신뢰성을 확보하기위하여 서울기상관측소의 1961년부터~2000년까지의 일단위 강우자료를 이용하여 검 보정을 수행하였다.

It is frequently found in daily life that people who experience good luck as lottery winners try to improve their background (e.g., home, car) but it has not been empirically validated why they do that. Present research attempts to explore the prediction that people who experience good luck expand the scope of attention to background and those who undergo bad luck shrink the scope of attention to adjacent objects. Findings from Experiment 1a indicate that participants who experienced good luck (won the rock-paper-scissors game) paid more attention to background and performed worse in the "find the hidden picture" (below FHP) task while those who underwent bad luck (lost the rock-paper-scissors game) paid more attention to objects, leading to better performance in the FHP task. It is also found in Experiment 1a that, if people washed their hands after experiencing good or bad luck, the opposite result occurred. Experiment 1b confirmed that the rock-paper-scissor game manipulated good and bad luck successfully and did not influence self-control. Experiment 2 shows that people who strongly believe in good luck performed poorly in FHP task while those who do not believe in good luck performed well in FHP task. Overall, three experiments support the proposed research hypotheses. Implications of the study findings for cognitive psychology and related fields including consumer and sports psychology are discussed.
