Purpose: The purpose of this study is the tooth decay ratio of the children and adolescents in four rural areas of Kyrgyzstan. Methods: Oral examinations were conducted 2,677 children and adolescents in Nizhniy chuy, Bokonbayevo, Chon Tash and Arashan from March 2017 to November 2019. It was investigated decayed tooth ratio(DT), decay permanent tooth ratio(DPT) and missing permanent tooth ratio(DMT) according to ages and areas by direct observation of the oral cavity. Results: In all areas, the rate of all children and adolescents aged 6 to 14 had very high DT of more than 94 percent overall. Furthermore, it was showed that high DPT rates above 78% on average and DMT over 8 years old in Chon Tash and Arashan. Conclusion: These results are higher than the average of DT, DPT and DMT in OECD countries. In order to promote oral health of children and adolescents, increased interest in oral health and policy measures at the Kyrgyzstan government level are considered urgent.

ICANN has been governing the Domain Name System(DNS) "technically" since 1998. The architecture is called Internet Governance, and it brings about many different discourses; "What does that govern?", "Who delegate its role to ICANN?"," How could the regime ensure fairness?" etc. This article will analyze on Internet Governance by applying the government approach of Foucault, and try to compare two parts, the 'core' and the 'edge' of Internet Governance for method. Whereas the 'core' of it refers the site that be governed by the formal contract directly, the 'edge' as the rest of it means informal friendly relations with ICANN. The 'core' rule was stemmed from technological community such as IAB or IETF historically. They had invented new world and its population to integrate the technical order as protocol and the semiotic order as language, that be based on new government mode. On the other hand, ".KR" domain, one of the 'edges', has been evolved into more heterogeneous system, through contest and conflict between traditional state and Internet Governance. The governed object of ".KR" domain is situated in the crossing of each other the 'protocol user', the 'language-semiotic user' and the' geographical resident'. Here the 'geographical resident' rule was weird for DNS, so that shows the internal lack of Internet Governance. It needs to move to the concept of 'Hangeul(Korean-language) user' rather than the 'geographical resident'.

This study purposed to analyze the preference of names in Korean hospitals. Names were analyzed in terms of hospital's characteristics such as hospital type, location, ownership. Also, multivariate regression analysis was applied to assess how the amount of information measured from their names was varied by the hospitals' internal characteristics. Yearbook of Korean Hospital Association in 2008 was used to collect the study data. The full name of hospitals was divided into meaningful words to investigate the preferred words. The amount of information in hospital names was measured based on the number of words extracted. The study results showed that hospitals preferred different words depending on their characteristics. The amount of information contained in hospital names tends to decrease between before and after year 2000. Korean hospitals increased the uses of Hangeul and foreign words for their names in recent years. These changes were considered as the responses of Korean hospitals to increase competitive advantages by establishing unique brand power.

"Japji" was an old cookbook written in 1721. There are 27 types of foods recorded in "Japji"; 10 descriptions of Byeonggwaryu (rice cakes and cookies): Yakgwa, Junggye, Mandugwa, Chaesugwa, Umujeonggwa, Dongajeonggwa, Baekjapyeon, Aengdupyeon, Toranbyeong, and Yeot; and 16 descriptions of Chanpumryu (side dishes): Jinjumyeon, Jeunggyetang, Geumjungtang, Eoreumtang, Changjajjim, Gajijjim, Oejjim, Dubuseon, Dubuneureumi, Geneureumi, Gesanjeok, Hodojaban, Jeonyak, Seokryutang, Sungeojuak, and Yangmandu. There is also a description of Gugija (Chinese wolfberry) liquor. Here, comparative analysis based on culinary science was carried out on the Korean foods recorded in "Japji" as well as the similar foods recorded in "Gyuhapchongseo" (Women's Encyclopedia) written around 1815. Of the 27 types of Korean foods recorded in "Japji", 13 were also found recorded in "Gyuhapchongseo". The time period for "Japji" can be assumed to be 1721 based on the fact that it is written in a cursive handwriting style of Hangeul, that chili was never used as an ingredient, and that the word "Shinchuknyeon (辛丑年)" was transcribed at the beginning of the book. The dating method also included considerations of whether Neureumi was used or not as well as changes in its cooking style.

Since parameters influencing the indoor environment of livestock building interrelate so complicatedly, it is of great difficulty to identify the exact cause of environmental problems in a livestock building. Therefore, the approaches for the problem solving based on experience not numerical calculation will be helpful to the management of livestock building This study was attempt to develop the decision supporting system to diagnose environmen- tal problems in a livestock building based on an expert system and a neural network. HClips$^3$), attaching the Hangeul user interface to Clips which is known as a powerful shell for develop- ing expert system, was used. The multilayer perceptron consisting of 4 layers including back propagation learning algorithm was adpoted, which was rapidly converged within the allowable range at 50,000 learning sweeps. The expert system and neural network seemed to work well for this specific application, providing proper suggestions for some environmental problems: particularly, the neural net- work trained by an environmental problem and its corresponding answer with certainty factor, produced the same results as those by expert system.

This study aims to discuss the basic foundations to set levels and language skills for developing a Korean Proficiency Test for young and adolescent learners. Recently, there has been an increase in demand regarding young and adolescent learners from multicultural and overseas backgrounds. However, the current Korean Proficiency Test lacks the appropriate means to determine the Korean proficiency of young and adolescent learners with general purposes of language learning. Therefore, there is an urgent need for developing a specialized and new form of language assessment for young and adolescent learners who are exposed to a foreign language or a second language learning environment. The study examines and analyzes cases of foreign language examinations for young & adolescent learners; furthermore, the objectives and target were set based on the results of a needs analysis and in-depth interviews conducted among teachers and education officials in overseas Korean Hangeul Schools, international schools, elementary and secondary schools. Finally, the levels and language skills appropriate for the objectives of a proficiency test and target learners have been suggested.

소전(素筌) 손재형(孫在馨)(1903~1981)은 한글 고체(古體)의 조형성과 필획의 장점에 주목하여 천재적 현대적 조형감각과 기발한 착상으로 전예서(篆隸書)에 접목하였다. 그리하여 천진난만(天眞爛漫)하고 해학적(諧謔的)인 독특한 서체로 승화시켜 동국진체를 계승 발전시켰다. 소전(素筌) 한글체는 점 획의 방향 전환, 획의 굵기와 길이 변화에 유의하여 각 점 획을 과장하여 표현하였지만, 장법과 구성에 무리가 없는 가운데 조화와 변화를 성취한 대교미(大巧美)를 발현하였다. 소전(素筌)의 공로는 한글서예 발전과 기틀의 전범(典範)이 되었을 뿐만 아니라, 현대서예에 새로운 공간 영역을 창출하였다는데 그 의미가 심대하다.

It is critical to identify the ruptured cerebral arteriovenous malformations (AVMs) for secondary prevention. However, there are rare cases unidentified on the radiological evaluation. We report on a patient with the delayed appearance of radiologically occult AVM as a probable cause of the previous intracerebral hemorrhage (ICH). An 18-year-old male patient presented with a right temporal ICH. The preoperative radiological examination did not reveal any causative lesions. Because of the intraoperative findings suggesting an AVM, however, only hematoma was evacuated. Disappointedly, there were no abnormal findings on postoperative and follow-up radiographic examinations. Eleven years later, the patient presented with an epileptic seizure, and an AVM was identified in the right temporal lobe where ICH had occurred before. The patient underwent partial glue embolization followed by total surgical resection of the AVM and anterior temporal lobe. Based on the literature review published in the era of magnetic resonance imaging, common clinical presentation of radiologically occult AVMs included headache and seizure. Most of them were confirmed by pathologic examination after surgery. In cases of the ICH of unknown etiology in young patients, long-term follow-up should be considered.
