지혜 깊어지는 건강 - 활기찬 실버 세대 - 잘 안 들리는 노인성 난청 부모님 귓속에 쏘옥 보청기

홍성화,Hong, Seong-Hwa 한국건강관리협회 2011 건강소식 Vol.35 No.2

노인성 난청(presbycusis)은 나이가 들어감에 따라 청력이 점진적으로 악화되는 것으로 성인 난청의 가장 흔한 원인중 하나이다. 미국과 마찬가지로 국내의 여러 연구에서 보면, 65세 이상의 노인 중 보청기를 착용해야 할 정도의 난청이 있는 비율이 전체의 30~35% 정도를 차지하고 있다. 이렇기 때문에 노인성 난청은 노인성 만성 질환 중 퇴행성 관절염, 고혈압에 이어 3대 만성 질환으로 분류되고 있다.

Plasma-derived products are produced from plasma via fractionation and chromatography techniques, but can also be produced by other methods. In the performance of nucleic acid amplification tests (NAT) with plasma-derived products, it is necessary to include an internal control for the monitoring of all procedures. In order to avoid false negative results, we confirmed the usefulness of the bovine viral diarrhoea virus (BVDV) for use as an internal control in the detection of hepatitis C virus (HCV) RNA in plasma-derived products. These products, which were spiked with BVDV, were extracted and then NAT was performed. Specificity and sensitivity were determined via the adjustment of primer concentrations and annealing temperatures. BVDV detection allows for validation in the extraction, reverse transcription, and amplification techniques used for HCV detection in plasma-derived products.

무선센서네트워크에서 LEACH 라우팅 프로토콜을 적용한 파티클 센서의 에너지 효율적인 알고리즘

홍성화,김훈기,Hong, Sung-Hwa,Kim, Hoon-Ki 한국시뮬레이션학회 2009 한국시뮬레이션학회 논문지 Vol.18 No.3

The sensor nodes that form a wireless sensor network must perform both routing and sensing roles, since each sensor node always has a regular energy drain. The majority of sensors being used in wireless sensor networks are either unmanned or operated in environments that make them difficult for humans to approach. Furthermore, since many wireless sensor networks contain large numbers of sensors, thus requiring the sensor nodes to be small in size and cheap in price, the amount of power that can be supplied to the nodes and their data processing capacity are both limited. In this paper, we proposes the WSN(Wireless Sensor Network) algorithm which is applied sensor node that has low power consumption and efficiency measurement. Moreover, the efficiency routing protocol is proposed in this paper. The proposed algorithm reduces power consumption of sensor node data communication. It has not researched in LEACH(Low-Energy Adaptive Clustering Hierarchy) routing protocol. As controlling the active/sleep mode based on the measured data by sensor node, the energy consumption is able to be managed. In the event, the data is transferred to the local cluster head already set. The other side, this algorithm send the data as dependent on the information such as initial and present energy, and the number of rounds that are transformed into cluster header and then transferred. In this situation, the assignment of each node to cluster head evenly is very important. We selected cluster head efficiently and uniformly distributed the energy to each cluster node through the proposed algorithm. Consequently, this caused the extension of the WSN life time.

분류체계 일치를 통한 과학기술정보 상호 교환 방법에 관한 기초 연구

홍성화,서태설,Hong, Sung-Wha,Seo, Tae-Sul 한국과학기술정보연구원 과학기술정보센터 2004 Journal of Information Science Theory and Practice Vol.35 No.3

과학기술정보의 의미적 상호운용성 문제는 빈번하게 발생한다. 잘 만들어진 분류체계는 상이한 데이터베이스 간에 의미상 불일치 없이 정보를 교환하기 위한 도구로 사용될 것이다. 하지만 각 데이터베이스가 취하고 있는 분류체계가 상이함으로 인해서 여전히 현실적인 장벽이 존재한다. 따라서 분류체계간의 일치 및 조화는 매우 시급한 문제이다. 본 논문의 목표는 다른 분류체계('국가과학기술표준분류'와 'KISTI 표준 분류')를 갖는 데이터베이스간의 정보 교환 시에 발생할 수 있는 의미적 불일치를 해결하는 것이다. 이를 위해서 과학기술의 개념적 체계 분석을 수행하였고 다섯가지의 일치/불일치 유형을 사례에 기반하여 분석하였다. The problem of semantic interoperability in science and technology information is frequently raised. Well-established classification scheme will be used as a tool to interchange information between different databases without semantic inconsistency. However, there is still a practical barrier due to different classification schemes each database adopts. Accordingly, it is urgent to harmonize or reconcile those classifications with each other. This paper aims to solve semantic inconsistencies occurred when interchanging information between databases having different classification schemes, the Standard National Sci-Tech Classification and the Standard KISTI Classification. For the purpose a conceptual analysis of science and technology are performed and five consistency/inconsistency types are analyzed based on some examples.

전쟁과 사절 -둔문해전(屯門海戰)과 명조(明朝)의 대외정책변화-

홍성화 ( Hong Sung-hwa ) 수선사학회 2017 史林 Vol.0 No.61

In the Age of Exploration, after the conquest of Malacca in 1511, Portugal had got information on China and steered its way to China. While Ming Dynasty put The Superintendency of Merchant Shipping(市舶司) in Canton which allowed foreign ships only for a tribute as `조공일원론`, local officials allowed its foreign trade in remote Tamao(屯門) or Nantou(南頭) which was 100km far away from Canton in reality. Staying in Tamao, Portugal sent Tome Pires to Beijing. But Beijing authority changed its attitude to Portugal, showing its wariness and boiling debates on banishment. This controversy led foreign policy to take a tough line through the death Zhengde Emperor(正德帝) and the appearance of Jiading Emperor(嘉靖帝) who oriented to Confucianism. In the meantime, the first and second Tamao battle occurred and Portugal was defeated in the war, being withdrawn to the ocean. On the other hand, the foreign policy of Ming Dynasty in early ages `tributary system monism(朝貢一元論)` which is `Tribute=Maritime Embargo Policy`. Following a brisk foreign trade, it is necessary to allow mutual trade(互市) gradually. mutual trade(互市) is a certain amount of tax collection for a trade through The Superintendency of Merchant Shipping (市舶司). It was classified by ① `tributary mutual trade(朝貢互市)` and ② `non-tributary mutual trade(非朝貢互市)`. In the middle of Ming Dynasty, ② was quite extensive and distinguished by The Superintendency of Merchant Shipping from Private Trade. At a time these debates on `non-tributary mutual trade(非朝貢互市)` were growing, Portugal timely came to China. However, expressing antipathy to the attitude and power of Portugal, Ming Authorities ceased its `non-tributary mutual trade` and returned to `tributary system monism(朝貢一元輪)` firmly. In this process, The Tamao battle broke out. Also, this naval battle was served as a momentum to make `tributary system monism` as a basic principle for foreign policy of Ming Dynasty firmly. Giving up the legal trade with China, Portugal caused many troubles such as a secret trade along the coast in China, joining with Japanese. In order to embrace them in a system, Ming Authorities had no choice but to choose the openning of Yue-Port(月港). From Ming`s perspectives, it was not a full permission to Private Trade but a series of trial to recover the marine order in a way of embracing Portugal as a `non-tributary mutual trade(非朝貢互市)`

東아시아 古代王權의 婚姻과 國際關係

洪性和(Hong, Sung-Hwa) 한일관계사학회 2018 한일관계사연구 Vol.59 No.-

본 연구는 동아시아 고대 왕권에 있어서 국제 혼인을 통한 국제관계의 실태를 고찰하는 것이다. 특히 백제의 경우는 초기부터 帶方, 신라, 왜 등과 혼인 관계를 맺음으로써 한반도諸國 중에서 주변국가와의 혼인 관계를 대표적인 대외 정책으로 사용하고 있었음을 알 수 있다. 그 중에서도 주목되는 것은 백제와 왜국인데, 백제 왕실과 야마토 왕실은 397년 아신왕대 이래 혼인을 통한 왕실교류가 행해졌다. 『日本書紀』에는 新齊都媛과 適稽女郎등 왜왕과 혼인 관계에 있었던 백제 왕실의 여인에 대한 내용을 일부 기록하고 있다. 그러나 腆支의 경우 왜왕의 혈족인 八須夫人과 혼인하였고 昆支의 경우도 倭왕실의 여인과 혼인하여 東城王을 낳았으며 豊璋의 경우도 倭系의 여인을 동반하고 백제로 귀국하고 있는 것을 확인할 수 있기 때문에 倭왕실과의 혼인 관계에 있었던 사실을 알 수 있다. 백제와 왜의 경우 상호 중첩되는 혼인 관계를 맺고 있었던 것을 그 특징으로 들을 수 있다. 당시 국제 혼인은 정치적 동맹이나 복속관계를 구축하는 중요한 요소였으며 그 기본적인 메커니즘은 중국-이민족간의 혼인을 통한 화친관계에서 찾을 수 있다. 중국왕조의 경우 漢이래 여타 국가와 화친관계를 성립시켰지만, 중국으로부터 주변국에 공주를 시집보내는 사례뿐만 아니라 주변국으로부터 중국에 왕족여성이 혼인을 위해 보내졌던 사례도 발견할 수 있다. 또한 중국왕조에서 보이는 혼인의 사례를 통해 보면 漢代에 일부 외교정책으로 채택되어 시작되었던 화번공주의 혼인이 五胡十六國시대로부터 北朝의 시대에 이르는 동안 활발하게 실행되고 있는 것을 볼 수 있다. 특히 北魏의 경우를 보면, 상호 중첩되는 혼인 관계를 통해 대내외적 입지를 강화하고 있는 것을 볼 수 있다. 한반도諸國 중에서 대표적으로 혼인에 의한 화친 정책을 외교 수단으로 삼았던 백제의 경우 倭왕실과 상호 중첩되는 혼인 관계를 맺었던 것은 당시 北魏에 있었던 혼인과 유사한 형태를 이루고 있었던 사례를 확인할 수 있다. This article aims to re-establish the international relationships that linked marriage and ancient royal authority in East Asia. Baekje (百濟) entered into marriage relations with Daebang (帶方), Yamato Wa (倭), and Shilla (新羅). This was a representative foreign policy among the countries in the Korean peninsula. In particular, the friendly relations among the ruling families of Baekje and Wa had continued since 397. In the Nihon shoki (日本書紀), we read of a woman of the Baekje royal family who married a man of the Yamato Wa ruling family. But we can find that men of the Baekje royal family, such as Junji (腆支), Konji (昆支), Pungjang (豊璋), and others married women of the Yamato Wa ruling family. The case of Baekje and Wa was characterized as mutually overlapping with the relations of international marriage. The basic mechanism can be found in the amity relations of international marriage between China and multiethnic nations. Chinese dynasties had established amity relations with other countries since the Han (漢) period, and the amity relations of international marriages operated actively from the Sixteen Kingdoms into the Northern Dynasty. In particular, this study shows that the Northern Wei dynasty (北魏) reinforced international status through mutually overlapping with the relations of international marriages. Thus, we could find that there were significant examples of the Northern Wei Dynasty (北魏) in the case of the international marital relations of Baekje and Wa.

The previous Water Leisure Safety Act that has been reformed in March 2005 obliges only a marine leisure business proprietor to insure compulsory liability insurance for the victims out of the operation of water leisure craft for business purposes, even though it does not provide any provisions for the protection of the victims out of the operation of water leisure craft for personal purposes. Hence the previous Water Leisure Safety Act has been reformed in March 2005 to protect the victims out of the operation of water leisure craft for personal purposes by means of obliging the private proprietor of water leisure craft to insure compulsory liability insurance, and to be effective from April 1st, 2006. Therefore, this paper examines the concept of water leisure craft for personal purposes, the utility and significance of liability insurance, and the principal contents of the liability insurances for water leisure craft for personal purposes that are currently used in UK and Japan, and inspects their problems and remedies.
