The semantic literature on definiteness and specificity shows that the former is relatively an established notion, whereas the latter is still a vague notion that needs to be more clarified and confirmed. Given this, Ionin (2006) argues for the reality of specificity based on the informal use of this. She proposes this in spoken English as a specificity marker which has a semantic feature indicating "peaker intent to refer" and "noteworthiness." She also provides as evidence the results of some crosslinguistics studies including an L2 acquisition study with both L1-Russian and L1-Korean L2-English learners. However, this paper will argue that the informal use of this does not seem to mark specificity according to Ionin's definition of specificity. It will also be argued that the L2 acquisition study cannot be used as evidence for the reality of specificity. Based on these arguments, this paper will try to redefine specificity, based on the notions of existence and uniqueness.

학문의 목적이 진리 탐구에 있고, 철학이 존재의 근원에 대해 물어간다는 측면에서 볼 때, 본질이 아닌 실존을 다룬다는 것은 철학의 본래적 의미와 거리가 있다. 그럼에도 실존을 말하는 이유는 현상학의 학문적 목표와 아주 밀접한 관련이 있기 때문이다. 현상학이 철학의 본래성을 회복하고, 엄밀한 학으로서의 철학을 정초하려 했다는 점에서 본질학이기도 하지만, 본질이 실존에서 출발한다는 점은 현상학적 연구에 있어서 간과할 수 없는 사실이다. 본 연구는 전통철학이 추구해왔지만, 놓쳐버린 문제들을 '실존' 의 문제를 고찰하면서 확인하는데 목적을 두고자 한다. 실존은 인간의 세계에 대한 참여이다. 따라서 실존은 세계-에로-존재로 표현된다. 지각된 모든 것은 전체적 통일성으로 파악되므로, 이념적인 본질로 환원될 수 없다. 결국 실존의 문제는 지각의 근원성에서 다시 출발해야 한다. 인간은 사유하는 존재이지만, 행위하는 존재이기도 하다. 여기서 사유한다는 것과 행위한다는 것 중에서 어느 것이 우선인가를 결정하는 것은 사실상 의미 없는 일이며, 문제가 되지 않는 것을 문제 삼는 일에 불과하다. 그러므로 우리는 데카르트의 코기토에 머무르지 않고 코기토가 열어준 문을 통해 열린 세계로 나아가려 한다. 이러한 이유로 본고에서는 실존의 문제를, 현상적 장과 현상적 몸을 중심으로 밝히려 한다.

Gaudi, Naber & Sackett pointed out that if an event is caused by a lens system containing more than two planets, all planets will affect the central region of the magnification pattern, and thus the existence of the multiple planets can be inferred by detecting additionally deformed anomalies from intensive monitoring of high magnification microlensing events. Unfortunately, this method has important limitations in identifying the existence of multiple planets and determining their parameters (the mass ratio and the instantaneous projected separation) due to the degeneracy of the resulting light curve anomalies from those induced by a single planet and the complexity of multiple planet lensing models. In this paper, we propose a new channel to search for multiple planets via microlensing. The method is based on the fact that the lensing light curve anomalies induced by multiple planets are well approximated by the superposition of those of the single planet systems where the individual planet-primary pairs act as independent lens systems. Then, if the source trajectory passes both of the outer deviation regions induced by the individual planets, one can unambiguously identify the existence of the multiple planets. We illustrate that the probability of successively detecting light curve anomalies induced by two Jovian-mass planets located in the lensing zone through this channel will be substantial. Since the individual anomalies can be well described by much simpler single planet lensing models, the proposed method has an important advantage of allowing one to accurately determine the parameters of the individual planets.

When humans explore the Moon, lunar caves will be an ideal base to provide a shelter from the hazards of radiation, meteorite impact, and extreme diurnal temperature differences. In order to ascertain the existence of caves on the Moon, it is best to visit the Moon in person. The Google Lunar X Prize(GLXP) competition started recently to attempt lunar exploration missions. Ones of those groups competing, plan to land on a pit of Lacus Mortis and determine the existence of a cave inside this pit. In this pit, there is a ramp from the entrance down to the inside of the pit, which enables a rover to approach the inner region of the pit. In this study, under the assumption of the existence of a cave in this pit, a 3D model was developed based on the optical image data. Since this model simulates the actual terrain, the rendering of the model agrees well with the image data. Furthermore, the 3D printing of this model will enable more rigorous investigations and also could be used to publicize lunar exploration missions with ease.

In this paper, we will introduce the general concepts of generalized multiobjective game, generalized weight Nash equilibria and generalized Pareto equilibria. Next using the fixed point theorems due to Idzik [5] and Kim-Tan [6] , we shall prove the existence theorems of generalized weight Nash equilibria under general hypotheses. And as applications of generalized weight Nash equilibria, we shall prove the existence of generalized Pareto equilibria in non-compact generalized multiobjective game.

In this paper we will prove the existence and uniqueness of the smoothest density with prescribed moments. The space of functions considered is the Sobolev space $W^2_m[0,1]$ and the target functional to be minimized is the seminorm $$\mid$$\mid$f^{(m)}$\mid$$\mid$_{L^2}$, which measures the roughness of the function f.

We introduce the fundamental theorem of upper and lower solutions for a class of singular ($p_1,\;p_2$)-Laplacian systems and give the proof by using the Schauder fixed point theorem. It will play an important role to study the existence of solutions.

Full univariate moment problems have been studied using continued fractions, orthogonal polynomials, spectral measures, and so on. On the other hand, the truncated moment problem has been mainly studied through confirming the existence of the extension of the moment matrix. A few articles on the multivariate moment problem implicitly presented about some results of this note, but we would like to rearrange the important results for the existence of a representing measure of a moment sequence. In addition, new techniques with orthogonal polynomials will be introduced to expand the means of studying truncated moment problems.

The role of switching costs in customer retention has been posited, but has not been subjected to rigorous empirical testing. Therefore, our main focus is on the factors that influence whether consumers will have intention to switch or stay with an incumbent technology (e.g., MS-Windows). Based on consumer survey with MS-Windows users, we find empirical support for the link between the existence of compactible software, consumer's expertise in MS-Windows and intention to stay with MS-Windows. Specifically, switching costs are found to be positively associated with the existence of compatible software. Further, the lack of expertise in MS-Windows on the part of consumers tends to increase the likelihood that they will rely on current MS-Windows, rather than switch to other alternative operating systems.

In recent years, a Zainichi playwright Jeong Ui Sin has been very active in the Korean theatre scene. However, the production of Yakiniku Dragon-first performed in Korea in 2008-which received numerous awards both in Japan and Korea gave him the recognition of Koreans' that was long overdue. In this paper, I will look closely into his two plays-Ineo Jeonseol (1990) and Yakiniku Dragon (2008)-which was written twenty-eight years apart from each other and reveal both similarities and differences between them in terms of the formation of post-colonial Zainichi identities. And to do so, I will utilize various opinions from post-colonial theories, performance studies theories, ethnic studies theories and theories on Zainichi Koreans. In the first, introductory chapter, I will delineate the theories on which this paper is based and some common factors of Jeong Ui Sin's 1990s plays as a point of departure. Then, I will move into the second chapter in which the two plays and actual productions of them will be closely examined to reveal different types of Zainichi identities and their social and cultural place within Japan by using Millie Creighton's concept of uchi others. In the third chapter, the identities of double negative (not not) and nomadic identities that are relevant to three types of Zainichi identity formation will be discussed. The fourth chapter will debate about various scholars' speculations about the future of Zainichi Koreans' identities and, finally, illuminate the changes/shifts that Jeong Ui Sin shows in terms of his stance as a Zainichi subject. In conclusion, even though it is very hard to speculate exactly what will happen to the Zainichi identity and their existence in Japan, the differences between the two plays-especially the endings-can be interpreted as revealing the changes in Jeong Ui Sin's Zainichi identity and it certainly sheds positive light on the future of the Zainichi identity and existence.
