This study analyzed individual-level and country-level factors affecting justification of domestic violence amid emerging social significance of family violence. For individual-level variables, prejudice against women in economic and social roles were used from the World Value Survey data. As for country-level variables, total of 36 countries were analyzed with indices that represents gender equality such as women's employment rate and democracy index. Women's employment rate was gathered from the Labour Market Database of the World Bank and democracy index was from the Economist Intelligence Unit. Results showed that both individual-level, prejudice against women in economic and social roles and country-level variables such as women's employment rate and democracy index had significant effects on justification of domestic violence. This result implies the importance of creating positive social culture which promotes positive attitudes towards perceptions of gender role and gender equality. As well, country-level endeavors to raise gender equality in employment deem important. Based on these findings, policy implications and recommendations for future research were discussed.

절차지향 프로그램으로부터 객체지향 프로그램으로 제공학 과정은 여러 단계를 거친다. 재공학은 객체 추충, 클래스 추출, 상속성 추출, 지속성 추출, 코드생성, 테스트등의 과정을 거친다. 변환 과정을 정당화하기 위해 테스트 단계에서 두 프로그램의 의미적 동일성이 검증되어야 한다. 이러한 검증과정이 없이는 변환이 무의미하다. 본 논문에서는 두 프로그램의 의미적 동일성의 의미와 검증에 대한 방법론을 제안한다.

모듈러 멱승은 주어진 값 X, E, N에 대하여 $X^{E}$ mod N으로 정의 된다. 모듈러 멱승은 대부분의 공개키 암호시스템과 전자서명에 사용되므로, 이 연산을 빠르게 수행하는 문제는 암호학 분야에서 중요하게 연구되고 있다. 본 논문에서는 모듈러 멱승을 효율적으로 계산하기 위하여, 멱승 계산을 위한 일반화된 그래프 모델을 제시하였다. 이 모델은 기존의 방법들을 대부분 포용할 수 있으며, 특히 새로운 방법을 개발하는데 유용할 것이다. 이 모델의 장점을 정당화하기 위하여 기존 알고리즘 중 가장 성능이 좋은 VLNW(Variable Length Nonzero Window)방법과 실험을 통하여 비교하였으며, 확장성이 높음을 확인하였다.

This paper analyzed pre-service teachers' justification of $0.99{\cdots}$=1 from their disproof of $0.99{\cdots}$ <1. Some pre-service teachers thought of the difference between $0.99{\cdots}$ and 1 as an infinitesimal. On the contrary, the others claimed that the difference between $0.99{\cdots}$ and 1 was zero as the standard real, but were content with their intuitive justifications. The pre-service teachers' limitation revealed in the process of disproving $0.99{\cdots}$ <1 can be closely related to the orthodox view: the standard real number system is the only absolutely true number system. The existence of nonstandard real number system in which $0.99{\cdots}$ is less than 1, shows that the plain question of whether or not $0.99{\cdots}$ equals 1, cannot be properly answered by common explanations of textbooks or teachers' intuitive justification.

This study aims to analyze mathematically gifted students' characteristics of generalization and justification for a given mathematical task and induce didactical implications for individual teaching methods by students' learning styles. To do this, we identified the learning styles of three mathematically gifted 6th graders and observed their processes in solving a given problem. Paper-pencil environment as well as dynamic geometrical environment using Geogebra were provided for three students respectively. We collected and analyzed qualitatively the research data such as the students' activity sheets, the students' records in Geogebra, our observation reports about the processes of generalization and justification, and the records of interview. The results of analysis show that the types of the students' generalization are various while the level of their justifications is identical. Futhermore, their preference of learning environment is also distinguished. Based on the results of analysis, we induced some implications for individual teaching for mathematically gifted students by learning styles.

In this paper, I attempted to show that 'Sorensen's Sorites' is not a successful argument for the vagueness of 'vague'. There are a lot of debates about it, but the central issue is whether Sorensen's Sorites is just small sorites; whether the vagueness certified by Sorensen's Sorites is just the vagueness of 'small'. Deas and Hull thought it was and rejected Sorensen's proof based on his sorites. But their rejection was rebutted by Varzi. The basis of his argument is that the subject of Sorensen's sentences - 'n-small' is vague - is not used but mentioned. I tried to reply on behalf of Deas and Hull and to show that the predicate 'vague' has not any effect on determining the truth value of "'n-small' is vague." Then it can be removed from the sentence. Of course I approve 'vague' is a homological term. What I do not agree with is only Sorensen's argument.

Self-defense is defined as 'an act which is performed in order to prevent impending and unjust infringement of one's own or another person's legal interest'(Article 21, the Criminal Act). To establish such a self-defense, it is generally suggested that it requires an intent for defense as subjective element as well as objective precondition of impending and unjust infringement of one's own or another person's legal interest' and considerable reason. Intent for defense which means an awareness for objective circumstance of self-defense is recognized as objective justification element for self-defense. With regard to intent for defense, there are various discussions on not only necessity of such an intent for defense but whether it is necessary for both actor's recognition of circumstance and specific purpose or motive and which should be applied for its punishment in case of lack of the intent for defense: consummated, unconsummated or semi-consummated. However, there is no clear regulations. This article reviews the contents of intent for defense based on opinion that it is necessary for intent for defense and then examines contents on criminal effect in case of lack of intent and intent for defense in case of criminal negligence.

The purpose of this study is to understand the effect of membership type for subscription service (individual subscription vs. group subscription) on continuous intention, and to verify the mediating effect of ease of justification and the moderated mediating effect of uncertainty. An experiment was conducted on 78 university students. As a result, consumers who use subscription services in group subscription showed higher intention to continue using the subscription service than consumers who use the subscription service in individual subscription. Also, the ease of justification mediates the effect on the intention to continue using. In addition, uncertainty was found to moderating effect of ease of justification on continuous use intention according to the type of subscription. This study understands the psychological mechanism of consumers according to the type of subscription service subscription and provides useful implications for companies that provide subscription services.
