A persistent maximum over the southern tropical Atlantic in the latitudinal tropospheric ozone distribution from the CCD method is seen in the latitudinal tropospheric ozone distribution from the TOMS-Pacific method. The tropical Atlantic paradox exists in the results of both the CCD and TOMS-Pacific methods. During the northern burning season, the latitudinal distributions in the tropospheric ozone derived from the TOMS-SAGE and TOMS-Sonde methods show higher tropospheric ozone over the northern tropical Atlantic than the southern Atlantic due to a stronger gradient in stratospheric ozone relative to that from the CCD and TOMS-Pacific methods.

This paper presents an intelligent computer system, which can easily diagnose electrical fire causes, without the help of human experts of electrical fires diagnosis. For this system, a database is built with facts and rules driven from real electrical fires, and an intellectual database system which even a beginner can diagnose fire causes has been developed, named as an Electrical Fire Causes Diagnosis System : EFCDS. The database system has adopted, as an inference engine, a mixed reasoning approach which is constituted with the rule-based reasoning and the case-based reasoning. The system for a reasoning model was implemented using Delphi 3, one of program development tools, and Paradox is used as a database building tool. To verify effectiveness and performance of this newly developed diagnosis system, several simulated fire examples were tested and the causes of fire examples were detected effectively by this system. Additional researches will be needed to decide the minimal significant level of the solution and the weighting level of important factors.

This paper is aimed at analyzing the effect of Information Technology (IT) investment on the output growth and Total Factor Productivity (TFP) of Korean stock industry. Data on 24 stock firms for the eleven years (1991-2001) are used for the analysis. It is identified that there are both direct and indirect impacts of IT investment of the Korean stock industry on output growth. The total effect on output growth is 1.34 percentage point per year, which divided into a direct effect of investment in IT on the output growth is 1.97 and an indirect effect on the TFP is -0.63 percentage points per year. Results show that IT investment cannot contribute to increased stock industry productivity. Therefore, the Korean stock industry has not benefited from increased investment on IT in increasing productivity, implying the so-called productivity paradox has existed during the period.

The modern society of the 21century is becoming a discussion as spaces appearing as ambiguous boundaries caused by complexed cultural phenomenon. As for the spacial factors we recognize, which appears as phenomenon in which is emphasizing the existing system of cognizance and thinking through drawing inviable parts of the effort within escaping the limits of gravity. This Merleau-Ponty and Gilles Deleuze refines it as theories called "Perception" and "Sense", and through the 'visible and invisible' of Merleau-Ponty and the 'Nonsense and paradox' of Gilles Deleuze, this study object is forming these inviable representations into space. Using the similarities of these two theories as a tool, we will analyze the examples of space with drawing the force that forms invisibility into embodiment, building a possibility of improvement in future spaces.

Researchers have different views on impact of information system use on productivity. The differences are fueled by 'the productivity paradox' insisted by Brynjofsson(1993). This paper intend to quantitate impacts of information system and to test the productivity paradox of using the information system. Restricted Maximumlikelihood Estimation(RMLE) method is applied on data from 81 farms adopting Pigplan system. The results find positive productivity improvement with information systems in swine farm. Adopting Pigplan system increases 0.52 in PSY(pigs per sow per year) and 0.087 in sow turnover. When it comes to region and farm size, region has impact on both PSY and sow turnover, while farm size does not. This result infers that local cooperatives, regardless of farm size, differentiate the impacts of the information system, implying that the ability to utilize information systems should be improved in organizational level.

With the development of information technology, social network services (SNS) such as Facebook and Twitter became popular and many users disclose their personal and sensitive information like private story, photographs and location information through posting and sharing. Despite the privacy concerns in SNSs, individuals continue to disclose their identity online. This phenomenon is called 'privacy paradox'. The purpose of this study is to examine the role of collective efficacy on self-disclosure in SNS context and to explain privacy paradox phenomenon. Drawing upon the communication privacy management theory, research model was developed and empirically tested with cross-sectional data from 306 individuals. Results revealed that collective efficacy has a direct positive effect on self-disclosure while privacy risk is negatively related to self-disclosure. However, privacy concern is not directly related to self-disclosure. The relationship between privacy concern and self-disclosure was moderated by collective efficacy.

Continuous quality improvement has generally been recognized as an essential requirement for a company to stay in business. For this reason, Six Sigma plays an important role In reducing cost and development time of a product and achieving high quality products in a competitive market. The Six Sigma has proven that it is possible to achieve dramatic performance improvement for conducting business. However, several recognized Six Sigma companies have suffered the financial troubles, even if the Six Sigma should be successfully deployed in their business organizations. In this paper, the reason of this paradox is represented and discussed for a successful Six Sigma deployment, including next generation of Six Sigma.

The progressive in English is taken to be an operator which takes a non-stative predicate and returns a predicate which denotes a process with a temporal frame around some definite time or event. When, it is combined with a predicate which has a culmination in the event, the sentence means that the culmination has not come yet. So the event denoted by the base predicate is not true at the current time. On the other hand, when it is combined with a predicate which has no culmination in the event, the event denoted by the base predicate is taken to be true. In this paper, this is explained by the semantics of the progressive based on the notion of contributiveness. I propose that a progressive sentence is verified by some subevents which are contributive to the current situation and the progress of the event beyond the threshold level of the event denoted by the base predicate. A sub-situation is contributive if the addition of it to the previous situation is more likely to lead to the whole situation than the previous situation.

The COVID-19 pandemic has highlighted the risks of an over-concentration of supply chains in one country. It has motivated stakeholders to pursue diversification strategies. However, a paradox exists. Stakeholders have shied away from a complete decoupling and preferring to selectively enhance economic ties with China. This article explores this paradox by examining supply chain concentration in China as a form of asymmetric interdependence and the countermeasures from the U.S., Japan, Australia, and India to minimize vulnerabilities. It argues that while the COVID-19 disruptions have brought to light the risk of supply chain overconcentration in China, countermeasures are also driven by coercive diplomacy and the deepening U.S.-China rivalry. The paper also examines the feasibility of diversification efforts by focusing on the capacity and capabilities of alternative supply chain hubs. It finds that while states are actively seeking ways to prevent China from using asymmetric interdependence of supply chains and trade to gain political leverage, there are structural limits to the degree of diversification in the short to mid-term.

The current research examines whether and when cause marketing, whereby firms link product sales to the support of a charity or cause, can increase charitable giving and happiness. Previous research suggests that cause marketing might reduce charitable giving and happiness among consumers. However, the present research finds the opposite result by introducing nostalgia as a moderator; cause marketing can enhance consumers' charity giving when their nostalgia is triggered. Moreover, results show that charitable giving increased by cause marketing improves feelings of happiness, suggesting that people view charitable behavior as a means of enhancing happiness. Interestingly, charitable giving and happiness are promoted by the situational priming of nostalgic events, but not by chronic individual differences such as nostalgia proneness.
