HL7(Health Level 7)은 보건의료 분야에서 ANSI에서 승인한 SDO(Standards Developing Organization)들 중의 하나이다. 대부분의 SDO들은 약제. 의료 장비 이미지, 보험 처리 등과 같은 보건의료 분야에서의 표준을 만든다. HL7의 영역은 진료와 병원 행정적인 부분이다. HL7에서는 Version2.3, Version2.4, Version3.0 등을 포함해 Data Model. Arden Syntax, CCOW(Common Context Object Workgroup) CDA(Clinical Document Architecture) 등의 표준을 만들어 나간다. 본 논문에서는 이 표준들 중 CCOW에 대해 알아보고. 기존 Agent System에 좀 더 지능적이고 자율적인 CCOW 서비스를 제공하는 방안을 알아본다.

Although the goals of HL7 Version 2(V2) and Version 3(V3) are identical, the concepts of the implementation and technological basis are different; this makes their versions inconvertible. This problem interrupts technological innovation advanced from V2 to V3 and has been raised as a new type of barrier in the field of medical information system. This study intends to develop software to convert V2 to V3 which can be utilized in the actual medical environment. Since it is practically difficult to develop the whole tools that automatically change total V2 messages into V3 messages, this article has designed, implemented, and tested the software that allows mapping between V2 and V3 which function as tools. In order to test this program, it has used ADT^A03 of five V2 messages to generate V3 messages. It is expected that the result of this research will be one of the new methods allowing conversion between V2 and V3.

Due to heterogeneity in Data and Processes, healthcare systems are facing the challenge of interoperability. This heterogeneity results in different healthcare workflows of each individual organization. The compatibility of these heterogeneous workflows is possible when standards are followed. HL7 is one of the standards that is used for communicating medical data between healthcare systems. Its newer version V3 is providing semantic interoperability which is lacking in V2. The interoperability in HL7 V3 is only limited to data level and process level interoperability needs to be catered. The process level interoperability is achieved only when heterogeneous workflows are aligned. These workflows are very complex in nature due to continuous change in medical data resulting in problems related to maintenance and degree of automation. Semantic technologies plays important role in resolving the above mentioned problems. This research work is based on the integration of semantic technology in HL7 V3 standard to achieve semantic process interoperability. Web Service Modeling Framework (WSMF) is used for incorporating semantics in HL7 V3 processes and achieves seamless communication. Interaction Ontology represents the process artifacts of HL7 V3 and helps in achieving automation.

본 연구는 HL7 버전 3의 객체지향 분석 및 개발 방법론인 HL7 개발 프레임워크(HDF)를 이용하여 투약관리의 임상문서구조의 개발을 통해 임상활동의 표준화 데이터 모델을 구현하는 것을 제안한다. 투약관리는 의료현장에서 임상전문가가 행하는 가장 중요한 업무이다. 표준화 된 데이터 모델 및 구조화된 병원정보시스템은 근거기반 임상 활동을 이루기 위해 상당히 중요한 과제이다. 임상문서구조를 생성하기 위해서 HDF와 제공된 도구들을 사용하였다. 본 연구자들은 투약관리활동에서 HDF의 각 단계의 다이어그램을 생성할 수 있었다. 그 결과, 임상 활동 중 하나인 투약관리에 대한 표준화 정보모델을 생성하였다. 이 모델은 보건의료정보시스템을 모델링하기 위한 정보통신개발자들에게 국제 표준방법론을 이해하기 위한 기본적 개념모델이 될 것이다.

The performance records of 410 Holstein Friesian crossbred cows belonging to seven genetic groups (Fl, 3/4, 1/4, 5/8, 3/8, triple cross and miscellaneous cross) maintained at Livestock Production Research Institute, Bahadurnagar, Okara were analyzed for various parameters of lifetime traits. For the analysis 2 data sets were made. Data set I included all the cows disposed off from the herd which have completed at least one lactation while for data set II performance traits for only first five lactations were considered. The data was analyzed by Mixed Model Least squares and Maximum Likelihood computer programme PC-I version. The least squares means ${\times}$ standard errors for data set I (periods are in days and milk yield is in litres) were $994.5{\pm}15.5$, $1,877.0{\pm}70.9$, $1,651.9{\pm}19.3$, $2,533.7{\pm}36.5$, $3,530.0{\pm}40.5$, $15,785.2{\pm}320.0$, $8.46{\pm}0.19$, $5.66{\pm}0.16$ and $3.79{\pm}0.08$, respectively for age at first calving (APC), Ist lactation milk yield (FLMY), productive life (PL), herd life (HL), total life (TL), lifetime milk yield (LTMY), milk yield per day of productive life (MY/PL), milk yield per day of herd life (MY/HL) and milk yield per day of total life (MY/TL). For data set II these values were $1,004.2{\pm}21.2$, $2,220.5{\pm}113.1$, $1,429.1{\pm}40.8$, $2,302.1{\pm}73.3$, $3,307.2{\pm}77.3$, $13,189.7{\pm}667.4$, $9.10{\pm}0.34$, $5.66{\pm}0.25$ and $4.02{\pm}0.18$ in the same order. For data set I the effect of year of first calving was significant for AFC, FLMY, PL, HL, LTMY and MY/PL. The season of Ist calving was significant only for MY/PL. The effect of genetic group was significant for AFC, FLMY, MY/PL and MY/TL while the effect of parity was significant for all the traits. For data set II the effect of year of Ist calving was significant only for AFC, FLMY and PL while the season of Ist calving was significant for FLMY and PL while the effect of genetic groups was significant for MY/HL only. The lifetime production performance is in general close to the various estimates reported in the literature.
