다중 목적을 지원해야 하는 실 세계의 복잡한 문제들은 현실적으로 다루기 어려운 규모의 문제에 직면하게 된다. 본 연구에서는 다중 목적의 대규모 영역에서 오류에 강인한 대화시스템을 구현하기 위한 2단계의 추론 방식을 제안한다. 발화된 슬롯의 추이와 히스토리 등 복합적인 요소에 의존적인 목적 영역을 CRF로 모델링하고, 영역 내에서의 세부 목표 값을 POMDP로 모델링하여 추론함으로써 오류에 강인한 정책을 도출하였으며, 이를 모바일 철도 예약 서비스에 적용하여 그 성능을 측정하였다.

Objectives : The aim of this study is to review studies that utilized domestic secondary data in Traditional Korean Medicine (TKM). Methods : We identified variables and values related to TKM of 24 secondary data sources, and searched studies from 6 databases (PubMed, RISS, KISS, NDSL, KMBASE, OASIS). Results : There were 13 secondary data sources including variables and values related TKM, and 23 articles were included in this study. Conclusions : It is necessary to develop high-quality secondary data sources that are suitable to TKM system in accordance with national policy.

Objective : This study aims to review clinical studies evaluating effectiveness of Korean medicine for smoking cessation. It also aims to critically analyze study design of the studies and suggest strategies for future clinical studies on smoking cessation. Method : Only domestic databases such as RISS, KISS, DBPIA, NDSL, and OASIS were searched from August to November 2011 for clinical studies on smoking cessation. There was no limitation on study design, period, and language. The studies were qualitatively analyzed focusing on study design including participants, intervention, and outcome measurements. Results : Out of 537 studies searched, 27 studies were included in the analysis. 56% of the studies were observational studies, 33% were quasi-experimental studies, and 11% were randomized controlled studies. 44% and 32% of the studies were conducted at educational institutions and hospitals, respectively. The average number of the participants were 182, which ranged from 15 to 1,056. Most of the participants were male. Intervention used were mostly auricular acupuncture, and the most frequently used acupoints were Lung, Shinmun, Endocrine, Pharynx & Larynx, and Inner nose. The average length of treatment period was four weeks, and the treatment was provided twice per week. The outcomes were measured at the end of the treatment and only 26% of the studies conducted follow-up measurements. 26% of the studies utilized questionnaires of which validity was evaluated and only 15% used objective measurements such as exhaled Carbon monoxide and Cotinine test. Conclusion : Though many clinical studies on effectiveness of Korean medicine for smoking cessation were conducted, there are still debates on quality of evidence. Recently, guidelines have been developed for clinical trials evaluating effectiveness of smoking cessation program. Thus, in the future, clinical studies should be developed based on these guidelines and designed to improve validity and reliability.
