We put forward a scheme of the theory of analysis, and G. E. Moore's theory of analysis is reconstructed. As C. H. Langford pointed out, Moore's theory commits to the paradox of analysis which says that if a analysis is correct then it is not informative, and if it is informative it is not correct. For, according to his theory, analysing statement is necessarily true identity statement and have some information. Moorean responses which is given by Max Black, Raymond Bradley and Norman Swartz, and Wilfrid Sellars rely on the distinction between the information about concepts and linguistic entity. These approaches are deficient in dealing properly with the difference in concepts as analysandum and analysans. Also, non-Moorean resolutions asserted by Myers, King, Black, and Earl are examined.

본 논문은 벡터자기상관(VAR) 모형과 벡터자기상관이동평균(VARMA) 모형을 사용하여 명목금리와 물가(도매물가)사이의 동태적 관계를 분석한다. 명목금리와 물가사이의 정(+)의 상관관계는 소위 $\ulcorner$깁슨의 역설$\lrcorner$로 불리워지고 있는데, 실증분석 결과에 의하면 한국의 경우 깁슨의 역설은 존재하지 않는 것으로 보여진다. 과거의 많은 연구들이 $\ulcorner$깁슨의 역설$\lrcorner$을 지지하는 실증결과들을 발견한 것은 관련변수들의 안정성(stationarity)을 고려치 않은 것으로 판단된다. 본 논문에서처럼 관련변수들의 안정성을 얻기위해 수준변수(예를들면, 도매물가지수) 대신에 차분되거나 증가율을 사용하고, 금리 및 물가이외에 두변수에 영향을 줄 수 있는 변수(예를들면, 통화변수)들을 포함하는 다변수 모형을 이용한다면 우리나라에서는 $\ulcorner$깁슨의 역설$\lrcorner$은 발견되지 않은 것으로 보여진다. 즉, 회사채 수익율과 도매물가상승율을 명목금리와 물가변수로 각각 사용하고, $1972.III{\sim}1991.III$사이의 분기별 자료를 대상으로 분석한 결과, 두변수 사이의 관계는 일방적 인과관계보다는 독립적인 관계로 나타나고 있다.

The growing interest in the privacy paradox involving discussions about discrepancy between attitude and behavior led to an increase in the number of studies on the topic. An in-depth theoretical review of the privacy paradox is essential to promote qualitative growth of domestic research in the privacy paradox. In this study, we conducted literature review of existing domestic studies in the privacy paradox. The results of this study showed that the quantity and the quality of research showed marked improvement. Earlier studies primarily focused on the existence of the privacy paradox phenomenon, but existing studies on the causes of the phenomenon gradually increased. Despite the use of various methodologies and analytical tools to investigate the causes of the privacy paradox, research in privacy paradox remains in its infancy. Further efforts are needed to achieve qualitative growth, and further studies should be conducted to introduce the behavioral economic approach. This approach posits that bounded rationality could contribute to a clear understanding of the privacy paradox and the academic development of the privacy field.

비트겐슈타인의 규칙따르기 개념에 대한 올바른 이해는 그의 후기 철학의 궤적을 살피는데 있어서 중요하다. 비트겐슈타인의 규칙따르기 문제에 대해 회의적 해석으로 유명한 크립키는 "탐구"의 201절을 문제 삼으며 '역설'의 문제를 새로운 형식의 철학적 회의주의로 간주했다. 본 논문은 규칙의 역설에 대한 크립키의 논증이 비트겐슈타인의 관점과 무엇 때문에 충돌하는지를 밝히면서 그와 함께 비트겐슈타인이 '규칙의 역설'을 제시한 궁극적 이유를 규명하는데 있다. 규칙의 역설에 대한 크립키 논증의 의의와 한계를 비판적으로 다룸으로서 필자는 다음과 같은 점을 주장할 것이다. 비트겐슈타인에게 있어서 규칙은 우리들의 행동을 이끄는 지침의 역할을 하며, 규칙의 문제를 추론과 연관시켜 수학이 엄격한 규칙을 따르는 인간의 지적 활동이며, 규칙에 대한 비트겐슈타인의 관점은 귀납적 회의주의와 무관하다. 이런 맥락에서 비트겐슈타인을 회의주의자 혹은 상대주의자로 평가하는 것은 문제가 있다. 그런 점에서 비트겐슈타인은 오히려 어떤 이론이나 선입견에 사로잡히지 않은 봄의 방식을 강조한 철학자로 평가하는 것이 옳다.

본 연구는 1980년부터 2000년 동안 9개 산업에서 정보통신 관련 자본(IT Capital Stock)을 이용하여, 해당 산업의 기술혁신에 기여도를 분석하였다. 순차적 분석방법에 따른 결과는 기술혁신을 나타내는 대리변수인 총요소생산성과 정보통신자본량이 단위근을 갖는 것으로 나타났으며, 두 변수사이에 장기적인 공분산 관계가 성립하였다. 정보통신자본이 기술혁신에 기여도를 분석한 결과는 사용하는 계량 추정량에 따라 정보통신자본의 1단위증가는 0.19에서 0.07까지 기술혁신에 기여하는 것으로 나타났다. 따라서 우리나라의 경우 정보통신자본의 Solow(1989)의 "생산성 역설"가설은 장기적 패널자료를 사용하여 분석한 결과는 정보통신자본의 Solow(1989)의 "생산성 역설"가설을 뒷받침하지 않는 것으로 나타났다.을 뒷받침하지 않는 것으로 나타났다.

Recently, remodeling construction project has been prevalently conducted in major city areas in Korea. However, remodeling construction project has a difficulty in conducting a construction because of non-existing drawing or lack of drawing information. To solve these problems, modeling techniques by using reverse engineering have been widely studied in other industries such as aerospace and automobile industry. But reverse engineering techniques have not been used in remodeling construction projects because those technology haven't supplied less accuracy during required time for surveying. So, this study suggests optimal method of acquiring accurate 3D laser scanner information for reverse engineering at interior remodeling project.

The main purpose of this study was to analyze the performance of a medium-altitude long endurance unmanned aerial vehicle through reverse-engineering method. The external configuration data of the RQ-1 Predator was reverse-engineered from related photos and specification data available on public domains, which also were used to generate the CATIA modeling and weigh distribution data of the UAV. The aerodynamic characteristics of RQ-1 Predator were mainly predicted the vortex lattice method and an empirical method, which the propeller performance was analyzed by the empirical method proposed by Howe. The rate of climb, service ceiling, range, and the loiter endurance of the UAV was analyzed, which showed good agreement with the reference data.

Recently, several studies in the field of privacy research suggested counterintuitive phenomenon about previous studies on existing perspectives. They claim that consistency of attitude and behavior does not exist, which is called privacy paradox. This study aims to clarify the relationship between intention to information disclosure and actual behavior based on the privacy paradox perspective. It attempts to explain the causes of privacy paradox phenomenon through the dual process theory being discussed in the field of behavioral economics. The results of empirical analysis are as follows. First, paired t-test analysis between intention to information disclosure and actual behavior was statistically significant. This means the existence of privacy paradox. Second, privacy risk had significant explanatory power to behavioral intention, and privacy trust had significant explanatory power to actual behavior. In conclusion, this study shows that negative belief influences decision making situation controlled by rational thinking whereas positive belief influences actual situations controlled by intuitive thinking.

The Purpose of this study is to test whether Braess Paradox (BP) can be revealed in a real world network. Fer the study, Namsan 2nd tunnel case is chosen, which was shut down for 3 years for repair works. The revelation of BP is determined by analyzing network-wise traffic impacts followed by the tunnel closure. The analysis is conducted using a network simulation model called SECOMM developed for the congestion management of the Seoul metropolitan area. Also, the existence of BP is further identified by a before-after traffic survey result of the major arterials nearby the Namsan 2nd tunnel. The model estimation expected that the closure of Namsan 2nd tunnel improve the network-wise average traffic speed from 21.95km/h to 22.21km/h when the travel demand in the study area and congestion Pricing scheme on Namsan 1st & 3rd tunnels remain unchanged. In addition, the real world monitoring results of the corridors surrounding Namsan 2nd tunnel show that the average speed increases from 29.53km/h to 30.37km/h after the closure. These findings clearly identify the BP Phenomenon is revealed in this case.

In this study, we classified SNS into open and closed types, and empirically examined in which SNS activity the privacy paradox holds. The idea comes from the argument that privacy paradox may be observed differently in the open SNS, which is more vulnerable to the leakage of personal information due to public profiles, and the closed SNS, which is relatively less vulnerable by limiting the range of acquaintances, The results of the empirical analysis are as follows. First, in case of SNS usage, the privacy paradox holds in the overall SNS activities, but different conclusions are drawn according to open and closed SNS. In particular, it is found that as privacy concerns increase, individuals respond in a reasonable and desirable way to reduce SNS activity in the open SNS, which is more susceptible to infringement. Second, in the case of SNS activity intensity, (i) heavy users are more seriously aware of the probability of privacy infringement than light users, so there is a reasonable response to reducing the intensive margin with increasing privacy concerns, and (ii) this tendency is more clearly observed in open SNS, which is more vulnerable to privacy infringement. Accordingly, insisting that the privacy paradox is empirically established by observing only the overall SNS activities without distinguishing them into open and closed SNS may be interpreted as a "Fallacy of Composition."
