The study was clinically performed in the 65 outpatients with pruritus who visited the Dept. of Dermatology, Oriental Medicial Hospital, Kyung Hee University and oriental medical clinic of Hang Ki Park from Jan. 1985 through Dec. 1986. The results were summarized as follows: 1. Among 65 outpatients, male was 20 ($30.8\%$) and female was 45 ($69.2\%$). In the distribution of age, 10S was $21.5\%,\;and\;20S\;20\%$ at the first visit. 2. In the distribution of season, the peak incidence occured in Spring ($35.4\%$) and next incidence in Winter ($20\%$). 3. In the distribution of duration, $41.5\%$ was between 1 year and 5 years, $20\%$ between 1 month and 6 months, $12.3\%$ between 6 months and 1 year, $9.2\%$ between 5 years and 10 years, $7.7\%$ over 10 years. 4. In regard to the itching lesion, $66.2\%$ showed pruritus throughout the whole body, including partially $15.4\%$ in their heads and faces, $12.3\%$ in their hands and legs, and $6.3\%$ in their shoulders, sides and hips. 5. The most frequently used prescription, was Gosanhomasan (苦蔘胡麻散) which occupied $60.7\%$ of all, in next order of frequency, Gamisamooltang (加味四物湯 $21.4\%$) Gupoongchongkisan (祛風淸肌散 $12.5\%$) and Bangpoongtongsungsan (防風通聖散 $5.4\%$). 6. In regard to the therapeutic duration, $46.2\%$ was showed under 10 days, $18.5\%$ between 10 days and 20 days, and $16.9\%$ between 30 days and 60 days. 7. In the 35 patients, who were confirmed to show apparent result by continual treatment, curative rate was more than $57.6\%$. According to above results, we can confirm that efficacy of therapeutic measures by the oriental medicine on pruritic dermatoses was increased in proportion to therapeutic duration and we feel sure that the therapeutic efficacy can be gradually increased as we expect to make a deep study of the disease and to give correct medical treatment to the nature of the disease.

Search engines, web portal sites, online book stores are being the main stream of information network. Library and its catalog has not influenced as the way it had been to the information network any more. Thus, institutions leading the bibliographic network started to pay much attention to the web user service. This article firstly reviewed the development of the bibliographic network, next generation catalog interface and OPAC 2.0, and investigated the case of OCLC in detail. Based on the reviews, this study suggested the development plan of bibliographic network focusing on the web user service in terms of the three strategies. It is hoped that this article will be the basic study for the future of the bibliographic network and the reference for the changes and improvements of libraries and catalog services.

In this paper, we adopt Storage Class Memory, which is next-generation non-volatile RAM technology, as part of main memory parallel to DRAM, and exploit the SCM+DRAM main memory system from the dependability perspective. Our system provides instant system on/off without bootstrapping, dynamic selection of process persistence or non-persistence, and fast recovery from power and/or software failure. The advantages of our system are that it does not cause the problems of checkpointing, i.e., heavy overhead and recovery delay. Furthermore, as the system enables full application transparency, our system is easily applicable to real-world environments. As proof of the concept, we implemented a system based on a commodity Linux kernel 2.6.21 operating system. We verify that the persistence enabled processes continue to execute instantly at system off-on without any state and/or data loss. Therefore, we conclude that our system can improve availability and reliability.

Colon cancer is one of the most common malignant tumors, but there are still a few validated biomarkers of colon cancer. Exosome-mediated microRNAs (miRNAs) have been recognized as potential biomarkers in cancers, and miRNAs can regulate a variety of genes. Recently, Fusobacterium nucleatum was discovered in the tissues of human colon cancer patients. Its role in colon cancer was highlighted. F. nucleatum may contribute to the progression of colon cancer through the mechanism of exosome-mediated miRNAs transfer. However, the exosomal miRNAs regulation mechanism by F. nucleatum in colon cancer is not well known. Thus, we performed next-generation sequencing to investigate the overall pattern of exosomal miRNAs expression in the colon cancer cell culture supernatant. We have confirmed the alterations of various exosomal miRNAs. In addition, to investigate the function of exosomal miRNAs, a Kyoto Encyclopedia of Genes and Genomes analysis was performed on the target genes of changed miRNAs. Potential target genes were associated with a variety of signaling pathways, and one of these pathways was related to colorectal cancer. These findings suggested that F. nucleatum can alter exosomal miRNAs released from colorectal cancer cells. Furthermore, exosomal miRNAs altered by F. nucleatum could be potential biomarkers for the diagnosis and therapy of colon cancer.

A retrospective study has been made of 170,026 cases of motor vehicle accidents which had been reported to the National Police Headquarters of Republic of Korea, 1983. Also a study has been made of 264 cases of road traffic casualties who were treated at the Eul-ji General Hospital from Jan. 1, 1983 to Dec. 31, 1983. This study was conducted to find out the nature and pattern of the traffic accidents from the clinical and epidemiological view points. In additions, the modes of injury from the road accidents were persued which might help to reduce the traffic accident rate. The results of the study were summarized as follows; 1. In this study, the highest incidence was in the age group between $21{\sim}30$ years (21.29%). And the age group of highest death rate was under 10 years (7.28%). 2. In the comparison of sexual differences, male was dominated in accidents number and death rate. (Casualty rate; 61.66%). 3. In the comparison of each hour differences, the accident was mostly occured during afternoon from 16:00 to 18:00(12.23%). 4. The most common day of week was Sunday (14.74%). 5. The most common season of year was Autumn (27.92%). 6. In the comparison of occupational differences, the high incidences were showed in labor men (31.06%) and business men (12.12%). 7. In the comparison of accidental vehicles, the most common vehicle were cars and the next were trucks and buses. 8. The most common mechanism of accidents was collision (57.41%). 9. In the comparison of clinical differences, orthopaedic and neurosurgical injuries were most common types of the hospitalized casualties. 10. In the comparison of anatomical fracture sites, the most common site was tibia (15.81%) and the next site was femur (12.56%).

In the society of the 21\ulcorner century under multiphase media conditions, the rapidly glowing electronic media will replace the conventional paper media in a variety of areas. However, if human being still has an affinity for paper media and an instinct for hardcopy from electronic-based text or image, the new market will be created for the paper industry. To what extent the consumer choses paper media for output will depend upon the availability of functions of paper media appealing to human senses; i.e., "sensory functions of paper". As a whole, on-demand type personal as well as business communications will increase in the next century and this trend will lead certainly to a rapidly expanding "contents hardcopy market". The technological progress of the paper industry in the 21\ulcorner century depends upon the market needs for higher products quality and higher efficiency of manufacturing process as well as an endeavour to overcome constraints from forest resource, energy, and environmental issues. Under the conditions with above constraints, the paper media will be polarized into two categories; (1)paper for higher image reproduction capability for original image or text and (2)paper for lower reproduction but with higher appeals for human senses. To cope with these trends, psycho-physical analysis and a sensory engineering approach for developing new paper media is vitally required. Also newly emerged roles of paper physics in the multimedia age is pointed out associated with sensory functions of paper that are not well-understood so far.

This study investigated the models of four countries' elementary mathematics textbooks in Ratio and Rate and identified how multiplicative perspectives on proportional relationships and the structure of proportion situations are reflected in the textbooks. For this, textbooks of 5th and 6th grade textbooks in Korea Japan, Singapore and U.S. are compared and analyzed. As a result, we can find multiplicative perspectives on proportional relationships and the structure of proportion situations on pictorial models, ratio tables, double number lines and double tape diagrams. Also, the development of Japanese textbooks from multiple batches perspectives to variable parts perspectives and the examples of the use with two models together implied the connection and union of two multiplicative perspectives. Based on these results, careful verification and discussion for the next textbook is needed to develop students' proportional reasoning and teach some effective reasoning strategies. And this study will provide the implication for what kinds of and how visual models are presented in the next textbook.

In this study, 4 indices of hydraulic & hydrological, geomorphological, eco & environmental, social effect and 38 items are selected to calculate impact range of downstream of dam. The Analytic Hierarchy Process(AHP) was applied to determine the priority of impact range calculation indices and items. As results of indices valuation, hydraulic & hydrological effect is the first priority, the second is eco & environmental, next are geomorphological and social effect. As results of items valuation, the design flood of dam is the first priority, the second is the natural flood & design flood of channel, next are the design flood rate of channel, drainage area and back water level caused by downstream of dam. In the case of Daechung dam, impact ranges were estimated 47.21 km in terms of the design flood of dam, 45.71 km of the design flood rate of channel, 13.94 km of the drainage area.

Greedy protocols show good performance in Vehicular Ad-hoc Networks (VANETs) environment in general. But they make longer routes causing by surroundings or turn out routing failures in some cases when there are many traffic signals which generate empty streets temporary, or there is no merge roads after a road divide into two roads. When a node selects the next node simply using the distance to the destination node, the longer route is made by traditional greedy protocols in some cases and sometimes the route ends up routing failure. Most of traditional greedy protocols just take into account the distance to the destination to select a next node. Each node needs to consider not only the distance to the destination node but also the direction to the destination while routing a packet because of geographical environment. The proposed routing scheme considers both of the distance and the direction for forwarding packets to make a stable route. And the protocol can configure as the surrounding environment. We evaluate the performance of the protocol using two mobility models and network simulations. Most of network performances are improved rather than in compared with traditional greedy protocols.

Due to the recent developments in computer vision technology, complex actions can be recognized with reasonable accuracy in smart cities. In contrast, violence recognition such as events related to fight and knife, has gained less attention. The capability of visual surveillance can be used for detecting fight in streets or in prison centers. In this paper, we proposed a deep learning-based violence recognition method for surveillance cameras. A convolutional neural network (CNN) model is trained and fine-tuned on available benchmark datasets of fights and knives for violence recognition. When an abnormal event is detected, an alarm can be sent to the nearest police station to take immediate action. Moreover, when the probabilities of fight and knife classes are predicted very low, this situation is considered as normal situation. The experimental results of the proposed method outperformed other state-of-the-art CNN models with high margin by achieving maximum 99.21% accuracy.
