Burst Error Channel의 에러 정정 기술로써 Reed-Solomon Product Code(RSPC)가 광범위하게 사용되고 있다. 그러나 Random Error Channel과는 달리 Burst Error Channel 상에서 RSPC의 에러 정정 평가 방법에는 많은 어려움이 있다. 우리는 이번 논문에서 Burst Error Channel 상에서 RSPC의 Error Correction Capability의 확률적인 계산 방법을 기술하려 한다.

본 연구에서는 산성전리수와 환원전리수의 미생물 제어력을 정량적으로 비교하였다. 산성전리수와 환원전리수에 병원성 미생물을 각각 시간별로 노출시킨 결과, 산성 전리수와 환원전리수 모두 미생물을 제어 할 수 있다. 특히 산성 전리수는 각종 병원성 미생물에 대하여 순간적으로 미생물을 제어하는 강력한 살균효과를 보여주었다. 이에 비해 환원전리수는 산성전리수의 강력한 미생물 제어력에는 미치지 못하기는 하지만, 시판되는 무기 항균제보다는 우수하거나 비슷한 미생물 제어력을 보여주었다.

광 디스크 channel상에서 RSPC의 error correction capability를 확률적인 계산 방법으로 계산하는 데는 많은 어려움이 있다. 그 이유는 바로 광 디스크 channel이 burst error channel이기 때문인데, 이 burst error를 어떻게 다루는 가에 따라 그 error correction capability는 사뭇 달라진다. 이 논문에서는 Sony의 dust error distribution[1] 아래에서 4-state Morkov Chain[2]로 modeling하고 그 결과를 가지고 burst error를 channel의 특성과 ECC format의 특성에 맞게 제어할 수 있는 확률적인 계산방법을 소개하고 그것을 simulation하고자 한다.

We present two kinds of construction methods for self-dual codes over $\mathbb{F}_2+u\mathbb{F}_2$. Specially, the second construction (respectively, the first one) preserves the types of codes, that is, the constructed codes from Type II (respectively, Type IV) is also Type II (respectively, Type IV). Every Type II (respectively, Type IV) code over $\mathbb{F}_2+u\mathbb{F}_2$ of free rank larger than three (respectively, one) can be obtained via the second construction (respectively, the first one). Using these constructions, we update the information on self-dual codes over $\mathbb{F}_2+u\mathbb{F}_2$ of length 9 and 10, in terms of the highest minimum (Hamming, Lee, or Euclidean) weight and the number of inequivalent codes with the highest minimum weight.

The Great Learning is an essential scripture of Confucianism that has had great influence on the politics, thoughts, society and culture of the East Asia which contains Korea, Japan and China. In case of Japan, the doctrine of Toegye(退溪) is flown into pre-Tokugawa era, and as the doctrine of Zhu Xi(朱熹) exercise influences over the other thoughts, the importance of the Great Learning is embossed relatively in Tokugawa era. The characteristic of Japanese confucianism of Tokugawa era is to lay weight on real world as such, and the Japanese confucianism has grown up academically centers on exhaustive reinterpretation about some Confucian classics. And Backho-Yoon Hyu(白湖 尹?), Seokye-Park Sedang(西溪 朴世堂) who lived in 17th century of Joseon dynasty attempt new interpretation about the Great Learning and they have an objection to the explanatory notes of Zhu Xi. In the same period of China, there are similar academic trends around Whang Jong Hi(黃宗羲), Ko Yeom Mu(顧炎武), Wang Fu Chi(王夫之). In other words, new views of real scholarship which reject emptiness and put much value on reality were current of thoughts that have been common to the oriental three countries in early and middle 17th century. The main object of this paper is to understand the attitude and understanding about the Confucian classics especially the Great Learning of the scholars who lived in early and middle Tokugawa era. It will be a decisive clue to understand the ninucture of thoughts system of them. Through these work, we understand how it has had influenced to thinking-ninucture and lives of the Japanese. And the other purpose of this paper is to understand characteristics of them when we compare that vking-ninucture and lives of the Japanese Confuciang-ninearly and middle Tokugawa era with in the same period of Jeseon and the later Ming(明) and early Ching(淸) dynasty.

In this paper, we design and implement middleware service modules of MiTS system architecture which is proposed for integrated shipboard information management. The MiTS system is divided to three layers that are gateway, middleware server and application. The gateway collects and parses information and data, the middleware server integrates the data and stores to a database, and the application displays visual data to users. The service modules provide MiTS middleware services to gateways and applications. We implement the service modules based on international standard IEC61162-4 series and test those.

Objective : Literary investigation of existing data was conducted to verify effects of Moschus and its herbal acupuncture, and determine quality management through component analysis. Results : Following results were obtained through literary investigation. 1. Deer musk (Moschus) is dried navel gland secretions of the adult male musk deer. 2. Moschus is known to be effective for treating various febrile diseases, to revive senses, heart and abdominal pain, complications from cerebral hemorrhage, angina, and others. 3. Single dosage of Moschus is between $0.03{\sim}0.1g$ and should not exceed 1g. Normally taken as powder or pill and may be used externally. 4. Moschus also has protective effects for the liver cells, and experiments revealed possible efficacies for hyperlipidemia, brain damage, hypertension, and etc. 5. For herbal acupuncture usage, Fel Ursi, Bezoar Bovis, and Moschus are used as a mixture (BUM), and it's known to be effective for protecting the liver and treating arthritis. 6. For component analysis of Moschus, aromatic matter 'muscone' should be used as a standard matter.

In this paper, we analyze and design requirements of Network Function block and System Function block of MiTS network protocol based on Light-Weight Ethernet, also implement and test the protocol and library files. Light-Weight Ethernet Protocol consists of Network Function block and System Function block. NF receives and sends datagram based on UDP multi-casting communication. SF processes messages after distinguished Sentence and Binary Image Data.

In these days, data processing rate is increasing on shipboard. To solve the problems on the rate, Ethernet based IEC 61162-4 series standard established for integrated information management. But the standard is difficult to implement, so it is changed into Light-weight Ethernet standard. In this paper, we analyze the existing standard and compare it with Light-weight Ethernet standard. As a result, we draw its service requirements. Also we propose the services, and design and implement the service modules.

Epidermoid cysts located in floor of mouth can be easily removed intraorally. The cysts inferior to mylohyoid muscle have been excised transcervically. However, an intraoral removal of a cyst extended inferior to mylohyoid muscle has not been reported yet. A 20-year-old female visited to the hospital with a cystic mass in submental region. Neck computed tomography revealed a 6.0${\times}$4.3cm sized circumscribed cystic mass in midline of submental area. The cyst lied external to the genioglossal and geniohyoid muscle, extending inferior to mylohyoid muscle. The mass was removed successfully by intraoral approach. It was performed under the exposure by the division of genioglossal and geniohyoid muscle, traction of the cystic wall after aspiration of the cyst, and digital compression externally.
