By use of the recent tropical cyclones' data in the Northwest Pacific Ocean, the occurrence frequency and region of typhoon as well as the features of the monthly mean track were analyzed. As the result of this study, (1) mean occurrence frequency of typhoon per year is 27.5, and 68% of total typhoons were formed in July to October and shown the highest frequency in August. (2) The ave-rage duration of typhoons is 8.5 days, and super typhoon which maximum sustained surface wind speeds is more than 130 knots occurs most frequently in October and November. (3) The highest frequency ap-pears around the Caroline, Mariana and Marshall Islands, and in wintertime, typhoon occurs in lower lati-tude comparing with those in summertime. (4) The typhoon track depends upon the distribution of pres-sure system and steering current in neighbouring areas. The mean track of typhoon can be classified into three types such as westward-moving type, northward-moving type and abnormally moving type. The west-ward-moving typhoons make landfall on the southern China by way of the South China Sea in June and July, on mid-part of China in August and September, and on Indo-china Peninsula in October and Novem-ber. The northward-moving typhoons approximately move on north~northwestward track to $20~30^{\circ}N$ from the occurrence region, then recurve to the East Sea through Korean Peninsula and Kyushu Island in June and July, to the Noth Pacific Ocean along the Japanese Islands in August and September and to the North Pacific Ocean through the seas far south off the Japan in October and November.

In this study, an ICT-based underwater communication monitoring device for underwater structures is implemented based on lifting fixture that transport human bodies found on the seabed to sea level. The lifting fixture is packaged with a retback, sideback, and cartridge that injects air. Monitoring systems are developed in a mobile manner in a portable structure. The underwater ultrasonic sensor signal is supplied using a USB port, and the O/S consists of Linux. For the underwater communication dong test, a measurement test was conducted in real time from 6m to 40m in depth on the east coast. The ultrasonic sound sensor is converted to 2,400 bps to verify the transmission error according to the duality. The communication speed of sensor to monitoring is 115,200 bps, and the speed of communication from controller to receiver is 2,400 bps. In the commercialization stage of the lifting device, it is easy to develop a low-end type and the compatibility is wide.

본 논문은 해양사고 시 인체 인양정보를 모니터링하는 시스템을 구현한다. 모니터링 시스템은 수중환경 정보를 송신하는 인양기구제어기를 통하여 초음파 통신을 수행하며, 수상에서는 관제센터 또는 모선까지 10 km내 GPS 정보를 제공하기 위해 LoRa 통신을 수행한다. 수중 인양제어기는 공압 센서, 자이로 센서 및 온도센서 정보를 전송한다. 수중조건은 수심 10m 마다 수압 1기압씩높아지고, 기구의 공기양은 육상에 비해서 1/2씩 줄어드는 환경에서 60 kg 수중 마네킹을 모델을 사용한다. 인양기구 SMB(SurfaceMarker Buoy)에 38g의 CO2 카트리지 1개를 사용하여 10 sec 이내에 수면 상승 조건을 기반으로 인양기구 출수 시험을 한다. 수중 통신은 수심 40m에서 100m까지 2,400bps 초음파 센서를 이용하여 데이터 전송환경을 구성한다. 모니터링 신호는 수심, 수온, 방향각 등을 수면 위의 구조요원에게 제공함으로써 인양작업자의 안전과 안전한 인체 구조를 목표로 한다. This paper implements a system that monitors human body lifting information in the event of a marine accident. The monitoring system performs ultrasonic communication through a lifting device controller that transmitsunderwater environment information, and LoRa communication is performed on the water to provide GPS informationwithin 10 km to the control center or mother ship. The underwater lifting controller transmits pneumatic sensor,gyro sensor, and temperature sensor information. In an environment where the underwater conditions increase byone atmosphere of water pressure every 10m in depth, and the amount of air in the instrument decreases by halfcompared to land, a model of a 60kg underwater mannequin is used. Using one 38g CO2 cartridge in the liftingappliance SMB(Surface Maker Buoy), carry out a lifting appliance discharge test based on the water level riseconditions within 10 sec. Underwater communication constitutes a data transmission environment using a 2,400-bpsultrasonic sensor from a depth of 40m to 100m. The monitoring signal aims to ensure the safety and safe humanstructure of the salvage worker by providing water depth, water temperature, and directional angle to rescue workerson the surface of the water.
「英語箋」と「改正增補英語箋」に關する比較分析 : 服飾の項目を中心にして
尹鍾和 기전여자대학 1995 論文集 Vol.15 No.-
幕末부터 明治初期는 日本語語彙의 發生 및 交替가 特히 顯著한 時期이다. 이 時期에 刊行된 「英語箋」(1861年刊). 「改正增補英語箋」(1872年刊)은 日本語語彙를 收錄한 貴中한 英學資料라고 볼 수 있다. 「英語箋」을 改訂한 「改正增補英語箋」은 각기 새로운 語彙의 收錄으로, 變動期의 日本語語彙의 反映에 充實하고 있다. 本稿에서는 「英語箋」과 「改正增補英語箋」과의 相互比較를 通해서 英學資料로서의 價値와 本質을 再定立하고자 하였다.

This paper's aim is to seize the intention of repair presented in the improved Gaesu Choˇphaesin'oˇ based on Wongan Choˇphaesin'oˇ by means of comparing two Choˇphaesin'oˇ. And this paper is also focused on the comparement of expression ways and distinguishing features of Korean and Japanese honorific expressions in two languages.

韓·日 兩國語의 敬語法을 比較言語學的인 見地에서 比較·硏究하려면 그 發達過程을 따라서 여러 각도로 考察해야 할 것이다. 그러나 本稿에서는 兩國語의 現代敬語法을 共時的으로 比較對照하는데 主目標를 두었다. 곧 兩國語의 現代敬語法의 基本體系와 表現形式을 相互比較함으로써 兩國 敬語法의 基本的 特質을 밝히고자 하였다. 兩國語의 比較·硏究는 兩國語의 親近關係 규명에 一助가 됨은 물론, 韓日, 兩國語의 本質 乃至는 文法硏究에도 도움을 주리라 본다.
