Men are ambivalent since they have good and evil at the same time. To concretize this evil further, men created symbolic icons of evil with formative elements by giving shape to it. Thus, this researcher would investigate and analyze the concept of evil and the formativeness appearing when the essence of humans' evil is expressed as symbolic icons. For this purpose, items for the classification of formativeness were constructed, and questionnaires were prepared to draw the results of an analysis as follows. As for the type of composition, symbolic icons of evil were expressed by pictures or signs, rather than letters. The objects of expression were characters and animals in myths. As for the layout, most were expressed in a radial shape. As for the method of description, most were in the forms of simplicity and complexity, and as for the outer form, most were circles. It was noted that the symbolic icons in which items with these types of composition had high scores, were drawn, used and developed in formative relations with each other.

This study analyzed the visual images covering 'weather' and 'weather forecast' in elementary science textbooks from the Syllabus Period to the 7th national curriculum from the socio-semiotic perspective. The results showed that most of the visual images were 'realistic' which were descriptive of real world phenomena. This means that most of the visual images in elementary science text were familiar to students in every curriculum period. The power relationship in communication between images and students was very complex. The visual images in elementary science textbooks include few geometrical and alphanumeric code in every curriculum period. This study provides a new framework to interpret amount of information, functions of information, structures, and social meanings of visual images. It could be also a beginning stage to introduce the socio-semiotic perspective into choosing visual images for next science textbooks.

최근의 정보통신은 하루가 다르게 기술혁신에 의한 변화를 맞이하고 있는 가운데, 기술이 시장을 주도하여 신기술이 시장구조를 변화시킴은 물론 정보통신 사업구조를 크게 개편시키고 있다. 정보통신망기술은 다양한 멀티미디어 정보를 대량, 고속으로 전송·교환할 수 있는 방향으로 발전되고 있으며, 단말기는 유·무선전화서비스를 비롯하여 영상정보까지 다양하게 송수신할 수 있는 보다 작고 간편한 멀티미디어 일체형으로 발전하고 있다. 서비스분야에서는 디지털화, 고속화, 광역화에 따라 문자, 음성, 영상 등이 통합된 멀티미디어서비스가 보급되고 있으며, 특히 '7년부터 상용화된 인터넷을 통한 전화와 방송서비스는 정보통신분야에 새로운 사업영역으로 등장하고 있다. 이로인해 기존의 통신사업 질서인 “유선통신 대 무선통신”, “기본통신 대 고도통신”, “통신 대 방송”의 개념은 무너져 버리고, 기술과 시장이 상호 융항되어 새로운 통신사업 구도를 형성시키고 있다. 이의 대표적인 사례는 인터넷분야이며, 기존의 전화사업은 물론 CATV등 방송사업에까지 시장잠식과 구도변화라는 형태로 커다란 영향 미치고 있다. 국내 정보통신 사업정책도 이러한 세계적인 추세에 따라 이미 지난해 별정통신 사업자의 신설 등 정책과 제도를 바꾸었으나, 기술혁신 속도보다 늦게 반응하여 사업초기에 혼란을 주고 있는 실정이다. 최근 기술에 의한 시장구조 변화에 대응하기 위하여 정부는 기존 국가 초고속망구축사업도 대폭 수정하여, 즉 모든 가입자선로를 광케이블로 연결하는 당초의 계획을 ADSL 등 기존 전화선의 활용과 WLL기술을 선택적으로 적용시키고 있다. 통신사업자들도 유선위주의 전송망과 가입자망을 LMDS, WLL 등의 무선통신망으로 구축하려는 현상이 나타나고 있으며, 정보통신 정책도 과거의 유·무선통신을 별개로 취급하던 정책에서 선회하여 겸업 또는 연계를 권장하는 방향으로 전환되고 있다. 이와같이 정보통신분야의 기술혁신과 새로운 서비스의 도입은 기존 서비스시장의 시장잠식은 물론 유·무선영역을 무너뜨리고, 고정사업자와 무선사업자간의 영역이 허물어지는 등 사업자구도를 크게 변화시키고 있다. 이러한 기술혁신의 영향으로 시장경쟁은 심화되어 단기적으로 기존 통신사업자의 경영수지가 악화되기도 하지만, 요금인하를 수반한 신기술서비스의 공급은 이용자 입장에서 저렴하고 양질의 정보통신서비스를 제공받을 수가 있으며, 장기적으로는 서비스이용 증가로 인해 전체적인 시장크기는 더욱 확대되어 통신사업자와 이용자 모두 효율성을 나타낼 수 있을 것으로 전망된다.

This study tried to suggest the development of a writing education model for Christian Universities based on both Hobbs' media education model and Vanhoozer's media text analysis model. This model consists of 6 steps- Christian worldview establishment, access, analysis and evaluation, creation, reflection and social action. This was developed in order to be applied for the class "reading and writing" of liberal arts. Also, this is an appropriate model for media text writing education aiming at an alternative creation activity through a critical comprehension of the complex texts consisting of sounds, images, letters and so on. Furthermore, this is designed to train the capable persons having intelligence, character, and spirituality balanced, whom the education of Chrisitian universities aims at. Finally, this model pursues the student-friendly and amalgamative text writing appropriate for a new era and has an advantage to raise the power of various forms of letter writing which all the universities should stress as well.

Kill Chain is getting attention due to North Korea's recent nuclear test and missile launches and has emerged the need for an early build up. In order to build a materialized kill chain, you should review the unique kill chain to support operations effectively using various sensors and striking weapon system. Especially, you need a suitable network to reduce a reaction time against the enemy attack under joint operations environment etc. Currently there are many communication ways(e.g. data link, voice, video and text message) used in operations through satellite, wired and wireless and so on. Now, this paper contains analysis on various means for target information exchange which are used in the kill chain. And appropriate network of the kill chain for target information transmission is addressed to confirm feasibility of its alternatives, which is developed using AHP(Analytic Hierarchy Process). Finally, this paper is suggesting network and means of its building up for target information transmission of kill chain which can be implemented under the situation of joint battle field.

Language models are essential in predicting the next word in a spoken sentence, thereby enhancing the speech recognition accuracy, among other things. However, spoken language domains are too numerous, and therefore developers suffer from the lack of corpora with sufficient sizes. This paper proposes a method of combining two n-gram language models, one constructed from a very small corpus of the right domain of interest, the other constructed from a large but less adequate corpus, resulting in a significantly enhanced language model. This method is based on the observation that a small corpus from the right domain has high quality n-grams but has serious sparseness problem, while a large corpus from a different domain has more n-gram statistics but incorrectly biased. With our approach, two n-gram statistics are combined by extending the idea of Katz's backoff and therefore is called a dual-source backoff. We ran experiments with 3-gram language models constructed from newspaper corpora of several million to tens of million words together with models from smaller broadcast news corpora. The target domain was broadcast news. We obtained significant improvement (30%) by incorporating a small corpus around one thirtieth size of the newspaper corpus.

Recently the artificial intelligence green house system, which collects automatically the informations of plants cultivation circumstances and controls the growing circumstances, is studied using temperature, humidity and illuminance sensors. In this paper, the inference for plants cultivation of optimum circumstance conditions is simulated on the internet bases by predicting the temperature, humidity and illuminance. On the IOT circumstances, the plant cultivation conditions of temperature, humidity and illuminance, using Arduino sensor, are transmitted to the manager on realtime and if the optimum condition of temperature and humidity for plant cultivation is not equal to the values, the system transmits automatically the SMS warning messages on realtime. Although the sudden climite conditions(snow, rain, hot weather) are occurred, the optimum condition of plant cultivation can be controlled. In this paper, using Fuzzy rules and WEKA TOOL, although the same flora temperature zone is used, the simulation is produced for the optimum value of temperature, humidity and illuminance for the zone.

Drivers need lots of information when they drive on the highway, however it is necessary and important to be provided information which is appropriate formation. In order to offer the suitable information, adequate size, quantity, and frequency of provided information are required for the drivers. To evaluate propriety of the expressed message of VMS that provides real-time traffic conditions, first of all, the amount of message about legibility distance and viewing should be estimated. In this research, drivers' characteristics of VMS message design were also reviewed to enhance the efficiency of VMS. And legibility distance, the amount of viewing information, and ratio of viewing information were analyzed on the currently operating VMS. The results of this study proposed that the appropriate size, quantity, and frequency were concluded by the legibility and memory of message on the real driving conditions. Consequently, these design methods of VMS could be expected to improve the transmitting capability of highway information to drivers.
