Seoul/Kyungki-born workers have higher wages than other regions-born workers. In order to determine whether this difference is due to taste or statistical discrimination, an econometric model is suggested and a test is done with it. According to the test, the hypothesis that the difference is wholly due to taste discrimination is rejected: a part of the difference is due to statistical discrimination. Since statistical discrimination in this paper comes out in the process of a worker's wage being determined according to his productivity, it is no problem for the government to intervene in.

The purpose of this research is to evaluate the quality of Differential Police Response strategy. Although it has been approximately three years since these new police response systems were introduced, there is no research to evaluate them empirically. Using two types of statistical quality control techniques, Xbar-R control charts for variables data and P charts for attributes data, this study analyzes approximately 3,000 calls reported throughout the year 2012 to the 112 Integrated Dispatch Center in Ik-san police station. The Xbar-R control charts revealed that the police did not consistently respond to an emergency call for service (i.e., code one case) within 3 minutes. The P control chart also identified that there was a significant variation in the portion/number of defective calls where police failed to respond to non-emergency calls for service within 5 minutes. The results from this study suggest the police may need to review the target response time for code 1 and code 2 respectively.

Designer creates new design alternatives using acquisition of visual information in design process. Which is more effectiveness to acquire in directive visual information or in-directive visual information\ulcorner In this research we would like to find out that the relation of character in visual information and design alternatives. So to A subjects, we give them to see directive visual information to make visual mental imagery, to B subjects, we give them to see in-directive visual information to make it. In this experiment they must crate telephone design. C subjects must evaluate this design alternatives by questions composing scale in distinction and elegant. After a experimentation, It is true that we make hypothesis that distinct two subjects in distinction and elegant. Though elegant is opposite with hypothesis. So to make elegant design. it is import to concentrate cognitive ability. Accordingly it proves that in-directive visual information is effective for new type design stage in design process and directive visual information is effective for new style design stage in design process.

Even though statistics is considered as one of the areas of mathematical science in the school curriculum, it has been well documented that statistics has distinct features compared to mathematics. However, there is little empirical educational research showing distinct features of statistics, especially research into the understanding of statistical concepts which are different from other areas in school mathematics. In addition, there is little discussion of a relationship between the ability of mathematical thinking and the ability of understanding statistical concepts. This study extracted some important concepts which consist of the fundamental statistical reasoning and investigated how mathematically high achieving students understood these concepts. As a result, there were both kinds of concepts that mathematically high achieving students developed well or not. There is a weak correlation between mathematical ability and the level of understanding statistical concepts.

The purpose of this study was to examine the mediating effects of empathy in relation to contact experience of the elderly and their knowledge level of ageing. For this study data was collected from 20th Dec. to 30th of Dec. 2018 355 university students from D university in J. province were surveyed. Data was analysis by using reliability test, correlation analysis, hierarchical multiful regression analysis. The statistical significance of the mediating effects was confirmed by Sobel's verification. The results of the analysis showed that the partial mediation effect of empathy was verified with regard to the relationship between elderly contact experience and discrimination of elderly people. In addition, the partial mediation effect of empathy was verified between level of aging knowledge and the perception of elderly discrimination. The results of this study confirmed the necessity of developing practical education and training programs to improve the level of aging knowledge and to increase contact experience with elderly people. There is also a need to enhance empathy in order to improve the awareness of discrimination against elderly people in health and welfare departments among university students.

This paper investigates the relationship between the occupational gender wage gap and the proportion of high wage earning female workers in Korea. The main idea is that an increase in the number of high wage earning female workers in the workplace could lead to a decrease in the gender wage gap by eradicating the prejudice or reducing the statistical discrimination on female workers. We constructed a panel dataset by using the raw data from the Korean Survey Report on Labor Conditions by Employment between 2009 and 2016. The result shows that greater presences of high wage earning female workers in male dominant occupations have statistically significant negative impacts on residual gender earning dispersion.

Q 방법은 인간의 태도와 행동을 연구하기 위해 철학적, 심리학적, 통계적, 그리고 심리측정과 관련된 개념을 통합한 방법론으로서 인간의 주관성을 정량적으로 분석할 수 있는 특수한 통계기법이다. 소비자의 인식, 가치, 태도, 신념과 같은 개념을 객관적으로 연구할 수 있는 방법으로서 가설 생성을 위한 탐색적 연구와 이론의 검증과 같은 확인적 연구에서도 적용될 수 있다. 많은 수의 표본을 대상으로 한 횡단적 R 방법에 비하여 개인이나 소집단에 대한 깊이 있는 탐구가 가능하다는 점에서 소비자 행동 연구에 유용성이 매우 높다. 개인의 주관성을 바탕으로 한 소비자 개인의 특성과 차별성을 이해하는 것이 마케팅 분야의 핵심을 이루고 있음에도 불구하고 그 동안 소비자의 주관성에 대한 깊이 있는 접근이 이루어지지 못하였다. 1935년에 심리학 분야에서 개발된 Q방법은 이를 분석할 수 있는 컴퓨터 패키지의 보급과 더불어 사회과학 전반에 걸쳐 그 활용이 확산되어 가고 있다. 이에 Q 방법의 과학철학적 특성과, 현재 널리 이용되고 있는 변수 중심의 R 방법과의 차이, 그리고 컴퓨터 분석을 포함한 구체적인 Q 분석방법 및 관리적 활용상의 문제점에 대해 논의하였다

본 논문은 브랜드 쌀 구매에 영향을 미치는 요인(factor)들이 소비자 특성에 따라 차이가 있는지를 분석하기 위한 목적으로 수행되었다. 분석을 위하여 서울시에 1,000명의 주부를 대상으로 설문조사를 실시하였으며, 그 주요 내용은 다음과 같다. 먼저 주부들이 쌀 구매에 영향을 미치는 11개 항목을 5점 리커르트 척도를 이용하여 분석하였다. 그 결과 소비자들이 가장 높은 점수를 부여하는 것은 쌀의 잔류 농약 정도로서 4.12점이 나왔으며, 영양가 높은 쌀(4.01점), 쌀알의 모양(3.96점) 및 쌀의 생산지(3.88점) 등의 순위가 높았다. 요인분석을 위해 고유치(eigen value) 값이 0.8 이상인 경우를 기준으로 요인 수를 분석한 결과 다섯가지의 요인이 추출되었으며, 그 특징은 유형적 차원과 무형적 차원으로 구분되었다. 전자인 유형적차원은 물리적 속성(완전미 여부, 도정일자, 잔류농약), 지역성(생산지), 외관성(크기, 모양) 및 가격성등의 가시적 차원으로 소비자가 쉽게 판단하거나 쌀간의 비교가 용이한 특성이며, 후자는 심리적 속성이나 상징성을 의미하는 것으로서 브랜드 상표와 품질 인증 마크가 가지는 신뢰성 등이 영향을 미치는 것으로 분석되었다. 무형적 차원인 식품의 안전성이 도시주부간 쌀 구매에 미치는 차별성을 알아보기 위하여 정규성 검정 결과에 따라 독립표본 T-검정을 실시하였다. 분석에서 도시주부가 특성별로 두 집단으로 구분되는 기준은 자의적 분류보다는 공통적인 기준을 이용하고자 평균값(나이, 학력, 소득, 동거가족 수)을 기준으로, 그 외의 경우는 더미변수(주부직업 유무, 주거형태 및 거주지역)를 이용하여 구분하였다. 식품의 안전성으로 추출된 요인 값의 평균에 대해 두 집단간 차이를 검정하였으며, 분석 결과 주거형태가 1％ 유의수준에서, 주부취업 여부 및 거주지역이 각각 5%유의수준에서 통계적 유의성이 있는 것으로 분석되었다. 반면 주부간 나이, 학력, 소득수준 및 동거가족 수에서는 유의미한 결과가 추정되지 못하였다. 본 연구결과를 볼 때, 식품의 안전성을 고려한 쌀의 마케팅 전략은 취업주부, 아파트 거주자 및 강남지역 주부들을 대상으로 한 판매활동 강화가 필요하다. 아울러 통계적으로 유의미한 결과를 나타내는 도시 주부의 특성 변수들을 세밀하게 구분해서 연구·분석하는 시장세분화 연구가 필요하다.

In this study, it was attempted to develop a grade-customized statistical analysis system that can be operated by a teacher without professional knowledge of statistics by utilizing profiling in the education sector. For this, with the convergence of techniques of profiling into the education sector, it examined the elements necessary for building a customized student multidimensional analysis system. Referring to the overall configuration and the current state to build multidimensional analysis system utilizing practical profiling, it showed the implementation result of the algorithm applied to each statistical method, and presented the differences and superiority to existing systems. Once the system based on the proposed techniques is built, considering differences of students' needs and abilities and clarifying precise objectives and standards, with the improvement of satisfaction in public education, it is possible not only to reduce expense of prior and private learning but also realize self-directed learning suitable to one's learning ability and aptitude.
