The automated visual inspection system (machine vision system) for quality assurance is important factory automation equipment in the manufacturing industries, such as display, semiconductor, etc. There is a lot of demand for the machine vision engineers. However, there are no technical training courses for machine vision technologies in vocational schools, colleges and universities. In this paper, we present the implementation of line scan camera based equipment for technical training of the automated visual inspection system. The training system consists of the X-Y stage which is widely used in machine vision industries and its variable image resolution are set to $10-30{\mu}m$. Additionally, this training system can attach the industrial illumination, either the direct illuminator or coaxial illuminator, for verifying the effect of illuminations. This means that the trainee can have a practical training in various equipment conditions and the training system is similar to the automated visual inspection system in industries.

Recently, the importance of self-directed learning has emerged in the fields of public education, private education, lifelong education, and vocational training education, in which learners can actively cope with knowledge in an infusion-oriented way. However, there are various theoretical knowledge such as concepts and strategies for self-directed learning, but the situation is insufficient for a system where learners can easily receive content in the academic field they want, depending on the actual self-directed learning operation plan or learning area. Therefore, since it is important to provide various learning content in this paper, we utilize text mining techniques to obtain appropriate information and refine and categorize the meaning. On-line, they want to study a system that provides a variety of content in the academic field that learners are trying to acquire.

The purpose of this study is to analyze the priority of curriculums on students preparing to become flight attendants using paired t-test, Borich method, and Herschknowiz's criticality function. As a result of this study, it was discovered that what flight attendants and students needed to study the most were foreign language subjects as English, Chinese, and Japanese. Therefore, a department of universities related to airline service should develop new curriculum to adapt to the trend of globalization. Also, flight attendants need curriculum including subjects related to tourism as an introduction to airline service. This means that the role of flight attendants needs to be expanded and specialized. In conclusion, a department related airline service should try to elevate its quality of education and design curriculum which will help flight attendants become specialists in their field.

In this study, gifted children's perceptions of scientists were investigated. The subjects were 91 elementary students who were registered in educational program for the gifted. This study was conducted using Draw-A-Scientist-Test (DAST) and questionnaires about the life of scientists. As the results, most scientists were depicted as well-featured and young people. There was a tendency that boys mainly described scientists as male, but girls as female. Many of the students perceived scientists as those who did significant works to try to help other people and pursue the novelty The general perceptions of the gifted on scientists were positive. Majority of students, however, perceived that scientists worked indoors with glassware or chemicals. Relatively, fewer students described books, other materials, and technologies including computer. Many of the students perceived scientists＇work as research or invention. Concerning working pattern, students mainly replied that scientists worked alone. In order to make students＇restricted perceptions enhance for opened and flexible manner, various educational methods need to be implemented.

The authors utilized two contested perspectives on the use and non-use of ICTs, especially the Internet, to verify three assumptions of urban ghettos as fundamentally excluded from the ICT structure, ghetto people as behaving in the same way, and deficiency as the sole explanatory variable of their non-use. The first assumption that the urban ghettos would be fundamentally excluded from the urban ICT structure can be nullified by our finding about the prevalence of ICTs in that area, albeit apparent lower level of access to ICTs compared to that of the urban core. The second assumption that the urban ghetto residents would display the same information behaviors would be challenged by our finding that the availability and usages of the Internet would be hardly consistent by gender, age, occupation, family size, and locational characteristics. The third assumption that deficiency would capture the Internet non-use by ghetto residents was found very tenable but could be rivaled by the choice perspective that use or non-use is simply a result of situated choice. Theoretical and practical implications were suggested.

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 paper, we analyze the comparative advantage of industry innovation (R & D) activities. The method is that companies are classified suppliers dominated- industry, productionintensive industries and science-based industries, and data of Statistical analysis were collected HCCP (KRIVET). The result is that Tipping phenomena of science-based is apparent and suppliers dominated- industry is the lack of comparative advantage. The implications are as follows. suppliers dominated- industries that specialize in R & D capabilities, support R & D capability is required. Second, the policy in terms of support for R & BD (linking technology commercialization support innovation) should be strengthened. Third, SMEs in the leveling down of industry R & D capabilities should be supplemented.

The purpose of this study is to investigate the economic deprivation of male-headed or female-headed households. Household having children under the age of 18 are categorized into three types according to the gender of household head: male-headed household, female-headed household, and dual-parents household. The findings from data, for this study came from the Korean Labor Panel Study in 2003. The analysis shows that the household's age, education, residence types, etc are key explanatory variables in determining whether to be in poverty. While the public income transfer is most effective in reducing poverty in female-headed households, the private income source is relatively more useful among male-headed families. Since single-household families are particularly at risk, public policy makers should pay special attentions to developing and expanding welfare-to-work programs which provides work incentives to overcome relative poverty and community networks on child care.

The subjects of this study were 180 elementary school students from multi-cultural families and general families. The purpose of this study was to examine the differences in self-concept and career development within two groups and the correlations between self-concept and career development. Also, it was to investigate the self-concept's effects on career development. The results were as follows: First, the children from general families showed higher academic-occupational exploration than those in multi-cultural families. Second, the self-concept had significant correlations with career development in both groups. And there were stronger correlations in children from multi-cultural families. Third, the regression analyses of two groups showed that academic self-concept had significant effects on career development in both groups, but there were higher effects in children from multi-cultural families.
