HL7메시지의 효율적인 저장과 검색을 위한 XML데이타베이스의 설계
이민경(Minkyung Lee),전종훈(Jonghoon Jun),정재헌(Jaeheon Cheong),최진욱(Jinwook Choi) 한국정보과학회 2001 한국정보과학회 학술발표논문집 Vol.28 No.2Ⅰ
HL7은 텍스트 기반의 의료정보교환 표준이다. HL7메시지는 한 환자가 내원하여 퇴원할 때까지 여러 종류의 메시지가 계속적으로 다량 발생하게 되는데, 그 메시지들의 일부 특정 세그먼트들은 반복적으로 생성되어 사용된다는 특징이 있다. 그러므로 HL7메시지를 데이타베이스에 저장할 때는 불가피하게 특정 세그먼트들에 많은 중복이 발생하게 된다. 또한 HL7메시지는 프로세스 흐름중심으로 발생되므로, 중복을 제거한 환자중심의 데이터베이스 설계가 필요하다. 본 논문에서는 XML데이타베이스를 사용하여 HL7메시지를 저장하는 방식을 제안한다. 이는 XML DTD가 병원정보를 다루는 여러 의료정보표준들 상호간의 정보교화 및 공유를 위한 스키마로서의 역할을 할 뿐만 아니라, 인터넷을 통해 여러 가지 서비스 제공할 수 있도록 효과적인 저장 및 검색을 지원하기 때문이다. 이질적인 병원정보시스템을 가지고 있는 병원들 간에 의료정보를 교환하고, 환자들의 의료정보를 통합관리 하기 위한 XML데이터베이스를 설계하고 구현하였다.

Purpose: In the rapidly changing business environments, salespeople play a significant role in maintaining a competitive edge and in increasing profits for businesses by making a long-term relationship with their consumers. Friendly kindness of sales workers can be a core strategy that enables companies to become more competitive, as sales workers are in the frontline of facing their services and products. Thus, this study examineds the effects of sale strategies by sales workers on earnings and attitudes consumers. Research design, data, and methodology: A survey was conducted on 200 customers who have purchased luxury cosmetics in their 20s or more through a specialized research institute. Survey instruments were designed based on preview studies to analyze variables in the research model. The researcher conducted Structure Equations Models (SEM) analysis to verify hypotheses after collecting 189 survey responses. Results: This research results are as follows. First, adaptive selling strategies positively affect consumers in terms of forming confidence in sales workers. Second, recommendation strategies also have a positive effect on confidence in sales workers and their psychological responsibility. Third, intensive strategies have a positive impact on psychological commitment and sales trust in sales workers positively impacts a steady relationship between consumers and sales workers and purchase intention. Lastly, psychological pressure has a positive effect on relationship continuity intention. Implications: This study investigated sales strategies of sales people that can affect customer attitude and relationship performance. The results of this study provide practical implications for salespeople and sales promotion managers, respectively. From the point of view of salespeople, we highlight what is an appropriate sales strategy to form a sense of trust according to the sales situation, and to make the customer’s felt obligations. In addition, this research shows sales promotion managers the direction of salesperson training suitable for various sales situations.
Diachronic study of Korean vowel elision : focusing on inflectional affixation
이민경(Minkyung Lee) 한국음운론학회 2004 음성·음운·형태론 연구 Vol.10 No.3
The aim of this paper is to examine the data showing vowel elision phenomena and provide a consistent and comprehensive analysis in the framework of constraints and their ranking. In V₁+V₂ sequence where an inflectional affix is adjacent to a stem ending in a vowel at a morpheme boundary, either vowel is elided to avoid vowel clash. In Mid-Korean, vowel elision is optional, thus multiple output forms take place. However, later that era, vowel elision becomes unexceptionally obligatory, thus optionality disappears. Such different aspects between two historical eras are due to ranking change. For the former, surface multiplicity emerges since two reversible constraints, Uniformity IO and Onset, are satisfied at the same time. Under reversibility, ranking variants of two adjacent constraints are responsible for emergence of surface multiplicity. For the latter, the ranking change from reversible to fixed renders only a single output form. Optionality is not expected. Further, the ranking change of different historical times affects the asymmetric vowel elision in Modern Korean as well. Some involve surface multiplicity while others do not. As such, diachronic change of vowel elision reflects constraints and their ranking change of different historical eras.
