사용자로부터 입력되는 비정형 데이터를 대화 형태로 이해하여 사용자가 원하는 정보에 대한 맞춤 서비스를 제공하는 챗봇은 모바일 서비스의 중요한 분야로서 주목받고 있다. 그러나 사용자의 자연 언어 형태의 질의 대화를 완전하게 이해하여 서비스할 수 있는 방법은 아직 미흡한 실정이다. 따라서 본 논문에서는 사용자가 음식점 추천을 위하여 입력하는 대화 문장으로부터 지역, 음식분류, 음식점명 등의 의미 단어를 추출하고, 추출된 단어를 SNS의 음식점 추천 관련 해시태그를 기반으로 구축된 지식 데이터베이스의 내용과 대조하여 통계적으로 단어 유사성이 가장 큰 사용자 목적 정보를 제공한다. 본 논문에서 구현한 음식점 추천 챗봇 시스템의 성능 평가를 위해서 웹 기반의 모바일 환경을 구축하여 다양한 사용자 질의 정보에 대한 접근 편의성을 측정한 결과, 기존 유사 서비스와 비교하여 터치 횟수와 화면 전환 횟수에서 각각 37.2%와 73.3%의 감소함을 보였다.

과학에서 지식의 불확실성은 명제가 현재 상태로는 참도 거짓도 아닌 불확실한 상태를 의미한다. 기존의 연구들은 학술 문헌에 표현된 명제를 분석하여 불확실성을 의미하는 단어를 수동적으로 구축하고 구축한 코퍼스를 대상으로 규칙 기반, 기계 학습 기반의 성능평가를 수행해왔다. 불확실성 단어 구축의 중요성은 인지하고 있지만 단어의 의미를 분석하여 자동적으로 확장하고자 하는 시도들은 부족했다. 한편, 계량정보학이나 텍스트 마이닝 기법을 이용하여 네트워크의 구조를 파악하는 연구들은 다양한 학문분야에서 지적 구조와 관계성을 파악하기 위한 방법으로 널리 활용되고 있다. 따라서, 본 연구에서는 기존의 불확실성 단어를 대상으로 Word2Vec을 적용하여 의미적 관계성을 분석하였고, 영어 어휘 데이터베이스이자 시소러스인 WordNet을 적용하여 불확실성 단어와 연결된 상위어, 하위어 관계와 동의어 기반 네트워크 분석을 수행하였다. 이를 통해 불확실성 단어의 의미적, 어휘적 관계성을 구조적으로 파악하였으며, 향후 불확실성 단어의 자동 구축의 확장 가능성을 제시하였다.

Study Design: Retrospective study. Purpose: This study aimed to investigate whether segmental lumbar hyperlordosis of the affected vertebra in patients with spondylolysis occurs only at L5 or also occurs at L4. Overview of Literature: To the best of our knowledge, increase in segmental lordosis of the spondylolytic vertebrae has only been investigated in bilateral L5 spondylolysis; it has not been examined at different levels of bilateral spondylolysis. According to the characteristics of segmental lordosis in bilateral L5 spondylolysis, patients with bilateral L4 spondylolysis may also have increased segmental lordosis of the L4 vertebra. Methods: Patients with bilateral spondylolysis of the L5 or L4 vertebra in 2013-2015 were retrospectively identified from the hospital database. Standing lateral lumbar radiographs were assessed for the angle of segmental lordosis of the L5 and L4 vertebra, sacral slope, and lumbar lordosis. The differences in segmental lordosis of the L5 and L4 vertebra, sacral slope, and lumbar lordosis were determined using non-paired Student t-test. Results: Overall, 15 cases of bilateral L4 spondylolysis and 41 cases of bilateral L5 spondylolysis satisfied the inclusion and exclusion criteria. Lordosis of the L4 vertebra was significantly greater in the bilateral L4 spondylolysis group ($24.2^{\circ}{\pm}7.0^{\circ}$) than that in the L5 spondylolysis group ($20.3^{\circ}{\pm}6.1^{\circ}$, p=0.047). Lordosis of the L5 vertebra was significantly lower in the L4 spondylolysis group ($27.7^{\circ}{\pm}8.2^{\circ}$) than that in the L5 spondylolysis group ($32.5^{\circ}{\pm}7.3^{\circ}$, p=0.040). The sacral slope and lumbar lordosis did not significantly differ between the groups. Conclusions: Adolescent patients with bilateral spondylolysis have segmental hyperlordosis of the affected vertebra not only at the L5 level but also at the L4 level.

Objectives: The purpose of this study is to review clinical studies of Traditional Chinese medicine (TCM) on Genito-Pelvic Pain/Penetration Disorder (GPPPD) in women. Methods: Key words "Dyspareunia", "Vaginismus" were searched on Chinese National Knowledge Infrastructure Database (CNKI) on April 21th 2019. Results: 2 case reports and 7 clinical trials were collected in accordance with the selection and exclusion criteria. Among the 7 trials, 4 were controlled trials, and 3 were single-arm trials. The types of intervention were herb medication in 8 studies, and compound TCM treatment including acupuncture, moxibustion, and cupping therapy in 1 study. All 4 controlled trials were about dyspareunia and conducted by herbal medicine of TCM. The study results and methods of intervention were analyzed. Conclusions: 2 case reports described the effectiveness of compound TCM treatments (acupuncture, moxibustion, cupping therapy) and herb medicine in dyspareunia. In 4 controlled trials, 2 trials described the effectiveness of herb medicine (oral or vaginal agent) compared to western treatment in dyspareunia, and other 2 trials described no effectiveness of herbal enema compared to danazol. In 3 single-arm trials, 1 trial of dyspareunia and 2 trials of vaginismus described the effectiveness of herb medicine. All the 9 selected studies reported improved or disappeared symptoms of GPPPD, or high effective rate after TCM treatment. There was limitation that the selected studies were retrieved from only one site of CNKI, and generalized results could not be derived, further studies should be carried out. Additional well-designed clinical studies on GPPPD in women are needed in Korea.

Objectives: The purpose of this study was to assess the effects of moxibustion treatment for Cardiac arrhythmia through a systematic review. Methods: Electronic database including Cochrane library, Pubmed, China National Knowledge Infrastructure, Embase, DBpia, and Korean studies Information Service System were searched by combining the keywords such as "arrhythmias", "cardiac arrhythmias", "心律失常", "moxibustion" and "艾灸". Through the searching, 5 randomized controlled trials(RCTs) were included except animal testing and cellular experiment etc. The quality of each RCTs was assessed using the Cochrane risk of bias tool. Results: We included 5RCTs involving 468 participants. Two RCTs compared moxibustion versus conventional treatment, another RCT compared moxibustion plus acupuncture versus conventional treatment, another RCT compared moxibustion plus herbal medicine verus conventional treatment, the other RCT compared moxibustion plus herbal medicine and ointment versus conventional treatment. These studies were evaluated by the efficacy rate of treatments. Studies measured outcomes in efficacy, heart rate, electrocardiogram and symptoms. Each of 5 trials statistically showed a significant differences in efficacy rate. One study reported about side effects and another study reported about complications. The overall risk of bias was unclear in 5 studies. Conclusions: The evidence suggests that moxibustion treatment may help to reduce cardiac arrhythmia, however, it is limited, low-certainty and we cannot rule out benefits or risks with this treatment. High-quality studies that report adverse effects are needed.
