This study was showed that although the meaning of a word is fuzzy and fluid without a distinctive boundary, we use it just like being fixed because we suppose that it can be defined as being fixed one. Therefore, this study was examined in the theories of the endeavors for catching a word essence and the various types on defining a word meaning. According to views of meaning, the theory of semantic atom, and the theory of semantic network, the essence of a word meaning was explained as a respectively different figure. In the theory of prototype, it is asserted that it has the most prototypical figure, in the theory of semantic atom, it is made up of the smallest atomic figure(or primitive) and can be taken apart, and in the theory of semantic network, it is revealed as the meaning qualities connected with a semantic network. The types of the definitions are examined in the viewpoint of a conventional definition, a encyclopedical definition, and a definition in language. Among them, the definition in language is showed that of a natural language form, in this study it was classified as the form and the substance of a definition and the defining ways of a meta language and a paraphrastic one were researched. This study was discussed that the lexicographers have done the various lexical definitions through choosing the form and the substance of a definition.
Non-Target Screening: A powerful tool for selecting environmental pollutants

An immense number of chemicals is produced, marketed, used by modern society and can be released into the environment through different pathways. Identification and quantitative determination of the emerging substances released into the environment through different pathways is still an analytical challenge for scientists since neither chemical nor spectral databases nor analytical standards are available. Gas and liquid chromatography hyphenated to a variety of accurate mass analyzers based on the use of high-resolution have been used for this purpose. We present an overview of the basic principles, promises and challenges of suspect and non-targeted screening (NTS) approaches current approaches based on high resolution accurate mass spectrometry (HRAMS) analysis, particularly based on software tools for data acquisition and data processing used for the identification of unknown the environmental pollutants. NTS has great potential for treatment assessment and pollutant prioritization within regulatory applications. We would like to introduce the main activities and especially harmonized protocols of the European Human Biomonitoring Initiative.

본 연구에서는 대구지역에 거주하면서 외식업체를 이용했던 경험이 있는 소비자를 대상으로 외식선호성향의 유형별로 나누고 외식선호성향 유형별 외식선택속성 및 고객행동의도의 차이에 대하여 실증적인 검증을 하는데 목적을 가지고 있다. 본 연구의 실증분석 결과를 통하여 다음과 같은 중요한 사실을 알 수 있었다. 첫째, 외식소비성향 집단을 군집으로 묶는 군집분석을 실시하였다. 도출된 5개 외식소비성향 요인의 K-평균 군집분석을 실시한 결과 맛추구형, 건강추구형, 경제가치추구형, 신속편의 추구형, 분위기추구형으로 분류되었다. 둘째, 외식소비성향 군집과 외식업체 선택속성의 관련성을 알아보기 위하여 외식소비성향 군집별에 따른 외식 선택속성에 차이가 있는지를 알아보았다. 분석의 결과에서 5개의 모든 외식선택속성에서 외식소비성향 군집 집단별로 통계적으로 유의한 차이가 있었다. 셋째, 외식소비성향 군집과 외식소비행동의 관련성을 알아보기 위하여 외식소비성향 군집에 따른 외식소비행동에 차이를 알아보았다. 분석 결과 외식소비 성향 군집에 따른 외식소비행동에 통계적으로 유의한 차이가 있는 것으로 나타났다. 추후 검증 결과 맛추구형, 경제가치추구형, 건강추구형, 분위기추구형, 신속편의추구형의 순으로 외식소비행동은 높은 것으로 나타났다. The objective of this study is to empirically examine differences in attributes of restaurant selection and intention of customer behaviors by type of consumers’ dining-out consumption propensity, based on a survey of customers living in the Daegu region who have an experience of dining out. Some of the important findings from the analysis are as follows. First, we conducted an analysis by grouping people of different dining-out consumption propensity into several clusters. Average values of the five extracted propensities were used for K-average cluster analysis, and the consumers were divided into five clusters: taste-oriented, health-oriented, value-oriented, convenience-oriented, and atmosphere-oriented. Second, we examined whether attributes of restaurant selection varied by different clusters to identify a relationship between clusters of dining-out consumption propensity and attributes of restaurant selection. The analysis results showed a statistically significant difference across the clusters for all five attributes of restaurant selection. Third, we examined whether dining-out consumption behaviors varied by different clusters to identify a relationship between clusters of dining-out consumption propensity and dining-out consumption behaviors. The analysis results showed a statistically significant difference across the clusters in terms of dining-out consumption behaviors. Dining-out consumption behaviors were greater in the order of taste-oriented, value-oriented, health-oriented, atmosphere-oriented, and convenience-oriented cluste
