Object : Traditional Korean Medicine Diagnostic Support System(TKMDSS) is the diagnostic prescribing system based on ontology developed by Korea Institute of Oriental Medicine. We monitored and assessed its usefulness and searched for improvements. Methods : We collected 10 cases of stroke inpatients of Dongguk University Ilsan Oriental Hospital. They were diagnosed by primary care physician and another researcher who monitored using "TKMDSS" respectively. We compared the process and results of two diagnosis. Results : The diagnostic concordance rate between primary care physician and researcher were pretty high. Most of the problems were caused by expressions on symptoms inappropriate use of terminology. The severity of symptoms and vague symptoms which is hard to be diagnosed should be reflected and measured in this system. Conclusions : The problems were about terminology and definition. The terminology should be defined accurately and in-depth detail so that anyone can get the right information. If the problems were modified, "TKMMSS" could be utilized as supportive measures for oriental medicine doctors and students.

Deep learning techniques such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) show superior performance in text classification than traditional approaches such as Support Vector Machines (SVMs) and Naïve Bayesian approaches. When using CNNs for text classification tasks, word embedding or character embedding is a step to transform words or characters to fixed size vectors before feeding them into convolutional layers. In this paper, we propose a parallel word-level and character-level embedding approach in CNNs for text classification. The proposed approach can capture word-level and character-level patterns concurrently in CNNs. To show the usefulness of proposed approach, we perform experiments with two English and three Korean text datasets. The experimental results show that character-level embedding works better in Korean and word-level embedding performs well in English. Also the experimental results reveal that the proposed approach provides better performance than traditional CNNs with word-level embedding or character-level embedding in both Korean and English documents. From more detail investigation, we find that the proposed approach tends to perform better when there is relatively small amount of data comparing to the traditional embedding approaches.

To investigate an eliminatory effect of mixed extract of Hovenia dulcis Thunb, Gastrodia elata and Alnus japonica etc., on the ethanol-induced hangover, 12 hr-fasted male Sprague-Dawley rats weighing 220±20 g were given mixed extract (10 mL/kg, p.o.) and administered ethanol at a dose of 3 g/kg bw (25% in distilled water) orally 30 min postdosing. Blood was collected from caudal artery at 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hr and then the animals were sacrificed at 24 hr after the ethanol treatment. From 0 to 12 hr, the administration of mixed extract significantly decreased the area under the serum alcohol concentrations-vs.-time curves by 21 % compared with control group. In these experiments, liver function indices, such as alanine aminotransferase, aspartate aminotransferase and sorbitol dehydrogenase activities, showed unaltered results in all treated groups compared with the normal group. These results suggest that oral intake of the mixed extract may be effective on elimination of ethanol-induced hangover.

In order to get the information needed for the preservation and application of Korean traditional dyeing techniques to modern textiles products, the present study analyzed the color and color differences of dyed goods according to the contents of fabrics and the traditional techniques of dyeing the Buddhist priests' robes. A spectrophotometer was used to measure the differences in achromatic color according to dyeing techniques, dyestuff, kinds of dyed fabrics, and after-treatment methods. Through experiments based on the traditional dyeing techniques used by Korean Buddhist priests, a total of 144 pieces of dyed fabrics were made and all the colors of those 144 pieces were analyzed. Among three dyeing techniques tested; (1) dyeing with a dye-bath made of ink stick that was ground down with water, (2) dyeing with a dye-bath made by shaking a bag containing ink powder in water, and (3) dyeing with a dye-bath made by rubbing a boiled ink stick on a fabric, dyeing with a dye-bath made of ink stick that was ground down with water was shown to be the best technique in terms of coloring. For fabrics, ramie was the best of all three techniques in terms of making achromatic color. Starching and rubbing was the most effective after-treatment method used on both fabrics dyed with a grounded ink stick and on fabrics dyed by rubbing a boiled ink stick on them. As a whole, yangyeonmook, made from minerals' soot, is better than songyeonmook, which is made by burning old pine trees or yooyeonmook, which is made by burning oils from seeds. Therefore, yangyeonmook could help to preserve and utilize the traditional dyeing techniques of Korea in a practical way in modern life.

이 연구에서는 무령왕릉에 사용된 전돌의 재료 특성에 관하여 고찰하였다. 압축 강도, 열전도도, 흡수율 등의 재료 특성은 비파괴 실험으로 측정하였다. 그 중에서 무령왕릉 전돌의 압축강도는 초음파 측정법과 흡수율을 이용하여 추정하였다. 실험 결과, 초음파 속도를 이용한 압축강도는 표면이 고르지 못하고 두께 편차가 큰 문화재 시편 특성상 표준편차가 크게 나타났다. 그러나 흡수율을 적용한 압축강도 값 (28.69 MPa ~ 33.19 MPa)은 일반 콘크리트의 압축강도 수준으로 편차가 낮게 나타났다. 따라서 초음파 속도를 이용하는 방법보다 흡수율을 이용하는 방법이 무령왕릉 전돌의 압축강도 예측법으로 보다 적합한 것으로 판단된다. 무령왕릉 전돌의 열전도도는 시료의 표면상태와 두께에 영향을 받지 않는 Mathis TCi를 이용하여 측정하였으며, 평균 1.58 W/mK로 흙에 근접한 값을 지닌다. 무령왕릉 전돌의 흡수율과 수분 잔류율은 각각 1.6 % ~ 15 %, 0 % ~ 0.7 %의 범위를 나타냈다.

Body movements of humans have emotions and these movements have meanings of 'Living Spirits' and 'Emotions'. Also emotions of humans indicate all body movements which are made within the environment. This study aims at providing new potentials to emotional design research methods not only by understanding the characteristics of visual perception according to body movements and but by investigating correlations between sequence which arise by the visual perception and emotions through experiments. As for the scope and method of this study, the emotional space designs were analyzed through the emotional theory study, SD method was used to evaluate emotions and the movements in the modern village and traditional village with similar elements were compared and analyzed for the empirical study. As a result, first it was confirmed waling hours in the traditional village took more than the modern village and it is thought movements of humans are affected by the visual environments. Second, it was confirmed values of the emotional evaluation were higher in the traditional village than the modern village. Third, according to a result of the correlation analysis between space sequence and emotions, it was closed with negative emotions such as 'Closed', and 'Complicated' from positive emotional words such as 'Natural'. 'Open', 'Curious', etc. as spaces are experienced more through movements in the modern village. On the contrary, the emotional intensity of the positive words such as 'In Harmony', 'Beautiful' and 'Warn' through movements in the traditional village increased as spaces were experienced more. As a result of this study, it was confirmed the time, space and emotions have correlations each other.

We introduce an introductory engineering education course for engineering majors and non-engineering majors. This course does not require any previous knowledge and experience on engineering. It requires strong curiosities and imaginations on current and future society we live in, where technology is inseparable ingredient. Course encourages attendees to explore fundamental issues of engineering: what is proper technology and what are proper ways of exercising engineering, issues dealt in soft engineering. Since course topics cover many aspects of technology, traditional learning methods fail to be successful and efficient. Various efficient learning methods have been proposed and implemented. We utilize various interactive tangible media, which include simulated thought experiments and physical media experiences. About 20 episodes in short film format are produced based on scenario written according to related issues selected. Physical media like interactive robots are introduced for attendees' stimulated experiences. We summarize our exciting experiments on interactive teaching experiences at Pusan National University which include on/off-line interactions, assignments, projects, and evaluations.

As the Internet is more embedded in people's lives, Internet users draw on new Internet applications to express themselves through "user-created content (UCC)." In addition, there is a noticeable shift from text-centered contents mainly posted on bulletin boards to multimedia contents such as images and videos on UCC web sites. The changes require different way of recommendations comparing to traditional products or contents recommendation on the Internet. This paper aims to design UCC recommendation methods with user behavior data and contents metadata such as tags and titles, and compare performances of the suggested methods. Real web logs data of a major Korean video UCC site was used to empirical experiments. The results of the experiments show that collaborative filtering technique based on similarity of UCC customers' preferences performs better than other content-based recommendation methods based on tag information and content metadata.

We report the first steps of a collaborative project between the University of Queensland, Polyflow, Michelin, SK Chemicals, and RMIT University, on simulation, validation and application of a recently introduced constitutive model designed to describe branched polymers. Whereas much progress has been made on predicting the complex flow behaviour of many - in particular linear - polymers, it sometimes appears difficult to predict simultaneously shear thinning and extensional strain hardening behaviour using traditional constitutive models. Recently a new viscoelastic model based on molecular topology, was proposed by McLeish and carson (1998). We explore the predictive power of a differential multi-mode version of the porn-pom model for the flow behaviour of two commercial polymer melts: a (long-chain branched) low-density polyethylene (LDPE) and a (linear) high-density polyethylene (HDPE). The model responses are compared to elongational recovery experiments published by Langouche and Debbaut (19c99), and start-up of simple shear flow, stress relaxation after simple and reverse step strain experiments carried out in our laboratory.
