Objectives The purpose of this case study is to report the effect of Gwakyangjeonggisangamibang on adenoidal hypertrophy. Methods The subject was a child with adenoidal hypertrophy. This patient was treated with oriental herbal medicine. The improvement was observed by subjective symptoms and A/N ratio, and OSA-18 survey was performed to compare quality of life before and after the treatment. Results After the treatment, the symptoms of adenoidal hypertrophy were relieved. A/N ratio of this child went down from 0.9 to 0.65. Also, the significant OSA-18 score change demonstrated that the patient's quality of life was improved. Conclusions This study showed that a conservative treatment using herbal medicine can be an effective choice for adenoidal hypertrophy before deciding to performing an adenoidectomy.

Objectives The purpose of this case study is to report the effect of Yukmijihwangtang-gamibang on recurrent hematuria in childhood. Methods The subject was a male child with macroscopic hematuria. This patient was only treated with oriental herbal medicine. The improvement was observed by subjective symptoms and routine urinalysis. Results After the treatment with Yukmijihwangtang-gamibang, the symptoms of macroscopic hematuria were relieved. The occult blood test was negative as well. The number of red blood cells in urine was within the normal range. He was less tired but hematuria did not recur even after intense exercise. Conclusions This study showed that Korean medical treatment with using herbal medicine such as Yukmijihwangtanggamibang can be an effective treatment option for asymptomatic macroscopic hematuria.

Objectives The purpose of this study is to analyze sinusitis patients who visited the department of pediatrics, OO Korean medicine hospital by using their age and to classify the clinical type by Korean medical theory. Methods The study was conducted based on 178 cases that consisted of sinusitis patients (from 1 to 15 years old) who visited OO Korean medicine hospital from March 2014 to March 2015. We analyzed the age of patients and classified them by the clinical type by reviewing patient's charts. After that, we compared the results with the results of previous studies. Results and Conclusions 178 Patients were studied. 2-years-age group was 19.7% of the study group which was higher than that of previous studies. The Lung-Kidney Yin Deficiency (肺腎陰虛) group was 33.1%, Wind-Heat (風熱) group was 29.8% and the Wind-Cold (風寒) group 18.5%, Spleen-Lung Qi Deficiency (脾肺氣虛) group was 15.7% and the Heart-Spleen Qi Deficiency (心脾氣虛) group was 2.8% of the study group. Children are full of Yang but lack of Yin (陽常有餘陰常不足) so they easily transform into heat and fire (化熱化火). The patients who had sinusitis were most likely to suffer from the common cold for more than a week, once a month. 45.1% of the people from the study group was suffered from common cold more than a week, and 43.8% of the people got common cold once a months. About 21.6 % and 18.3% of the people got common cold twice a month and once every 2 months, respectively. The remaining 15.7% got cold during the season changes.

한국어최적상호명코퍼스설계에관한연구

이선정,Lee, Sun-Jung 한국컴퓨터산업학회 2004 컴퓨터産業敎育學會論文誌 Vol.5 No.5

In this paper, we obtain an optimal corpus that can represent its characteristics very well from the baseline corpus which consists of unique 1,566,943 names among company names in a directory assistance serve (114). Two kinds of optimal solutions ared considered to obtain the optimal corpus. The first solution is to find phonetically balanced corpus (PBC), which are the minimum set including all possible triphones in the baseline corpus. The second solution is to find the phonetically distributed corpus (PDC), which is a minimum set representing the frequency characteristics of triphones in the baseline corpus. We can obtain 8,699 words as the PBC and 16,783 words (similarity measure R = 0.92) as PDC, respectively. These corpora can be used for the development of speech recognition and speech synthesis. 본 논문에서는 114 안내시스템에 저장되어있는 서로 중복되어 있지 않는 1,566,943개의 상호명 코퍼스에서 이 코퍼스의 특징을 가장 잘 표현 해 줄 수 있는 최적 코퍼스를 설계하였다. 최적 코퍼스를 구하기 위해 두 단계의 방식을 택한다. 일 단계는 기본코퍼스에 존재하는 트라이폰이 모두 나타내는 최소의 단어 셋을 구하는 최적 음소균형 코퍼스 셋이고 다음 단계는 기본코퍼스에 존재하는 트라이폰의 빈번도를 고려하는 최소의 단어 셋을 구하는 음소 분포코퍼스 셋을 설계하였다. 실험 결과 최적 음소 균형 셋으로 8,699단어가 선정되었으며 최적 음소 분포 균형 셋으로 16,783 단어가 선정되었다. 이러한 최적 코퍼스는 음성 및 합성 시스템을 위한 음성데이터베이스를 구축 할 때 이용된다.

본 연구는 최근 차량 Instrument Panel 에서 사용자가 받아들여야 하는 정보의 양 증가에 따른 사용자의 혼란을 감소시키기 위해 주행 중 차량 Instrument Panel 조작 방식으로 적절한 Interface 를 제시하고 실험 및 설문조사를 통해 검증하는 데 주목적이 있다. 본 연구의 실험에서는 주행 중 Visual Interface 와 Auditory Interface 를 중심으로 운전자의 퍼포먼스 및 정확도와 설문을 통한 운전자의 만족도를 측정하였다. 본 연구에서 시행 된 연구 결과는 다음과 같다. 퍼포먼스는 Auditory Interface 에서 더 높게 나타났으며, 정확도는 Visual 및 Auditory Interface 두 Interface 사이에 유의한 차이가 나타나지 않았다. 설문조사 결과 Visual Interface 실험의 난이도와 만족도 사이에는 유의한 차이가 있는 것으로 나타났으나, Auditory Interface 실험의 난이도와 만족도 사이에는 유의한 차이가 없는 것으로 나타났다. 본 연구의 결과는 차량 Instrument Panel Interface 에 대해 퍼포먼스 및 정확도를 중심으로 접근함으로써 차량 Instrument Panel Interface 의 개발자들에게 이론적, 실무적 근거를 마련하여 준다. This study aimed at suggesting adequate interface for automobile instrument panel and validates the result through experiments and survey. To help drivers with their confusion caused by increased information of instrument panel, this study analyzed the effect of visual interface and auditory interface on driver’s performance and accuracy. The result of experiments showed that performance and accuracy are higher on auditory interface experiment than visual interface experiment. We also conducted a survey in order to measure driver’s satisfaction on each interface. The result of the survey showed that there existed strong significant difference between level of difficulty and driver’s satisfaction on visual interface experiment but not on auditory interface experiment. The result of this study provides both theoretical and empirical evidence to automobile instrument panel interface designers.

활성화 확산 모형을 이용한 아이콘 평가

이선정(Sun Jung Lee),명노해(Rohae Myung) 대한인간공학회 2007 大韓人間工學會誌 Vol.26 No.4

Icon conveys symbolic information which they have become ubiquitous as main element of GUI. However, users often cannot intuitively understand its functional meanings. Icon has to be designed for users to easily understand functional meanings. In order to evaluate icon, the spreading activation model can be used to effectively understand the process of information retrieval. In asymmetric spreading activation model is that in the two nodes the degree of spreading activation is different according to direction. Thus, asymmetric spreading activation theory was performed evaluating the strength of association when users see visual image to associate their verbal meaning (visual image - verbal meaning pair) and users see verbal meaning to associate their visual image (verbal meaning - visual image pair). According to the direction, this study hypothesizes that the well-designed icons have symmetric relationship rather than asymmetric relationship between the two pairs. The strength of association is measured through the reaction time and the accuracy rate. In performing SAT (spreading activation test), the ten icons were selected as word processing software icons. After first SAT, newly designed icons were developed based on Korean mental model, and second SAT was conducted using them. The results showed that the accuracy rate of newly designed icon has been improved. Also there is significant difference of reaction time between current icons and newly designed icons. Well-designed icon is confirmed that the strength of association relationship arises symmetrically rather than asymmetrically between the two pairs. User centered icons could be designed by improving the strength of association between the two pairs. Asymmetric SAT evaluates the strength of the association between the visual image and the verbal meanings to contribute to the development of icon which it related to human's association structure.

이선정(Sun-Jung Lee),박윤주(Yoon-Joo Park),박성공(Sung-Kong Park),문창주(Chang-Joo Moon),백두권(Doo-Kwon Baik) 한국정보과학회 1999 한국정보과학회 학술발표논문집 Vol.26 No.1B

웹 환경의 기존 멀티데이타베이스의 질의는 일반 사용자가 사용하기에는 복잡하고, 동적인 전역 스키마의 구성과 유지보수의 어려우며, 자유롭게 새로운 데이타베이스의 연합이 계속되는 동적인 웹 환경에 적응력이 떨어진다. 이런 단점을 해결하기 위한 방안으로 개념 기반 질의를 제안한다. 개념 기반 질의는 주어진 개념 하에서 멀티소스를 하나의 소스처럼 질의할 수 있도록 하였다. 개념 질의를 위해, 멀티데이타소스의 이질적 스키마의 속성들을 개념 기반으로 하였으며, 이로써 일반 사용자는 보다 쉽고 풍부한 개념 기반 질의를 표현할 수 있다.

효과적 질의 처리를 위한 메타데이터 기반 실체 뷰 관리 기법

CORBA/JAVA 기반의 멀티데이터 소스에 대한 통합 질의 환경에서 많은 사용자가 질의를 동시에 수행함으로써, 질의 처리 성능 문제가 나타난다. 이러한 문제점을 해결하기 위해서 본 논문에서는, 메타데이터를 이용하여 분할된 질의에 대한 실체 뷰(Materialized view)를 관리함으로써, 질의 처리를 향상시키는 기법을 제안한다. 제안된 기법은 자주 사용되는 실체 뷰를 캐쉬에 유지시키으로써, 재사용율을 높이고, 질의 절차를 감소시켜, 중복되는 질의의 반복 수행을 줄인다.
