In 1997, Dr. James Chien-Min Sung patented the technology of making diamond tools according to a predetermined pattern. The optimization of this pattern may double the tool life and the cutting speed. In 1998, Sung also made $DiaGrid^{(R)}$ saw segments that showed superior performance in cutting granite and marble. In 2000, Sung visited Shinhan and introduced them this revolutionary concept of diamond saw segments. In 2005, Shinhan adapted the idea and produced saw segments with diamond grits set in a predetermined pattern, their results confirmed that the sawing speed and the sawing life were both improved over conventional designs.

The Purpose of this study was to identify the dimensions and pattern types for the perception of Korean traditional food and to find the determinants of the pattern types, taking food cultural background into account. Data were factor and cluster analyzed, and the results revealed two different dimensions and pattern types. Descriptive statistics showed that perceptional pattern types, i.e., traditional-modern pattern and tradition-oriented pattern, are likely to vary depending on socio-demographic and cultural background of Korean traditional food in Korea. Similarities and differences in perceptional pattern types are discussed, and future implications for food and nutrition specialists and food marketers are provided.

현대사회에서는 다양한 산업 기술의 고도화와 함께 여러 가지 재료와 집적기술의 발전으로 화장품 산업 전반에도 많은 종류의 화장품이 출시되고 있는 실정이다. 이와 함께 화장품법의 독립과 화장품의 전 성분 표시제가 도입되었다. 웰빙시대인 요즈음에는 질 좋은 삶의 추구를 위해 생활관리, 생체리듬, 올바른 자세, 스트레스 증상과 같은 생활패턴에도 많은 관심을 갖게 되었다. 이들 생활패턴은 삶의 질과 건강뿐만 아니라 피부 관리와도 관련이 있을 것으로 판단하여 기능성 화장품의 인지도와 생활패턴과의 관계를 알아보기 위하여 설문조사를 하였다. 그 결과는 화장품 인지도 관련 16문항 중 문항 3, 문항 5, 문항 6 및 문항 11은 대학교 간 응답에 유의한 차이가 있음을 보였다. 또한, 생활패턴과의 교차분석 결과는 응답연도와 스트레스 증상 간, 응답연도와 올바른 자세 간에는 응답에 유의한 차이가 있음을 보였다. 끝으로, 성별과 생체리듬, 성별과 올바른 자세 및 성별과 스트레스 증상 간에는 응답에 유의한 차이가 있음을 알 수 있었다. 향후 과제로는 일반인을 대상으로도 동일한 조사를 하여 이들간의 차이를 조사해 볼 필요성이 있는 것으로 생각된다.

The purpose of this study was to collect and analyze personal bio data and social network services (SNS) data, derive user preference and user life pattern, and propose intuitive and precise user modeling. This study not only tried to conduct eye tracking experiments using various smart devices to be the ground of the recommendation system considering the attribute of smart devices, but also derived classification preference by analyzing eye tracking data of collected bio data and SNS data. In addition, this study intended to combine and analyze preference of the common classification of the two types of data, derive final preference by each smart device, and based on user life pattern extracted from final preference and collected bio data (amount of activity, sleep), draw the similarity between users using Pearson correlation coefficient. Through derivation of preference considering the attribute of smart devices, it could be found that users would be influenced by smart devices. With user modeling using user behavior pattern, eye tracking, and user preference, this study tried to contribute to the research on the recommendation system that should precisely reflect user tendency.

선물 및 옵션의 만기결제와 관련된 정보비대칭 상황은 각 투자자 집단의 거래활동에 가시적인 영향을 줄 수 있다. 이러한 가능성을 조사하기 위해서 본 연구는 만기일을 제외한 파생상품의 life cycle을 시간의 경과에 따라 3개의 구간으로 설정한 후, 각 투자자 유형의 거래활동이 각 구간별로 보이는 변화 패턴을 조사하였다. 조사된 KOSPI200 지수 파생상품시장의 투자자 유형별 거래행태는 Foster and Viswanathan(1990)의 전략적 유동성 거래자 모형을 통해서 해석되었다. 한편, 투자자 유형별로 KOSPI200 지수 파생상품의 만기결제와 관련된 정보우위성을 측정 및 비교함으로써 정보비대칭 정도 및 정보거래자의 확인(identification) 문제에 조금 더 접근할 수 있었다. 본 연구의 주요 결과는 다음과 같이 요약된다. 첫째, 투자자 집단의 거래활동은 KOSPI200 지수 파생상품의 life cycle에 따라 3가지 유형(ㄱ자형, L자형, U자형)의 패턴으로 요약된다. ㄱ자형은 만기일 이전 1주일 동안 거래활동을 축소하는 패턴이고, L자형은 만기일 이후 1주일 동안 거래활동을 확대하는 패턴이고, U자형은 만기일 이전 1주일과 만기일 이후 1주일 동안 거래활동을 확대하는 패턴이다. 둘째, 개인투자자는 파생상품 life cycle과 관련하여 대형주 종목군을 대상으로 ㄱ자형 거래패턴(선물만기 기준)과 U자형 거래패턴(옵션 단독만기 기준)을 보인다. 이러한 거래패턴은 Foster and Viswanathan(1990)의 전략적 유동성 거래자 모형의 예상과 일치하였다. 셋째, 파생상품 life cycle과 관련하여 외국인투자자의 거래행태는 부분적으로 전략적 유동성 거래자 모형의 예상과 일치하였으나, 기관투자자의 거래행태는 전략적 유동성 거래자 모형의 예상과 무관하였다. 우리나라 주식시장의 전체 거래규모에서 가장 큰 비중을 차지하는 개인투자자가 파생상품의 만기와 관련하여 전략적으로 유동성 거래를 수행한다는 점은 파생상품의 life cycle이 주식시장에 주기적으로 영향을 주는 중요한 경로임을 의미한다. 본 연구는 이러한 경로를 새로이 규명하였다는 점에서 의미를 가진다.

The principal objective of this study was to assess the dimensions and pattern types for the perception of Korean traditional food of Uzbeki-Koreans and to find the determinants of the pattern types, taking food cultural backgrounds into account. Data were collected from 634 Koreans living in Uzbekistan and were factor- and cluster-analyzed. The results revealed three different dimensions and pattern types. Descriptive statistics demonstrated that perceptional pattern types, i.e., tradition recognized patterns, traditional living patterns, traditional modernized patterns, are likely to vary depending on socio-demographic and cultural background of Korean traditional food in Uzbekistan. Similarities and differences in perceptional pattern types are discussed, and implications for food and nutrition specialists and food-marketers are provided.
