Bridge lanterns are installed on bridges or piers to signal the presence of these structures on navigational routes and navigable waters, and they fall under the category of light wave signals in Aids to Navigation. In Korea, medium to large bridges installed over major rivers and seas are equipped with bridge lanterns, which are necessary for routes frequented by ships and require periodic inspections on a monthly or multi-month basis. However, most bridge lanterns are mounted externally on bridge railings as fixed or manual rotary supports, posing a high risk of fatal falls during inspections. Furthermore, high -traffic bridges demand quick maintenance works due to complaints about traffic disruption, thus increasing work hazards. Consequently, this study introduced a tailored automatic bridge lantern support concept based on different types of bridge lantern installations, aiming for safe and rapid inspections. Additionally, the study sought to achieve full automation of the bridge lighting system by integrating it with a management program for monitoring and controlling bridge lanterns, utilizing both wired and wireless communication technologies. These findings provide foundational design data for new and refurbished bridges that will be installed in the future.

This study examines the performance of and searches for improvements to the existing automatic fire detection systems installed at domestic apartment buildings as a basic study for development of intelligent fire detection systems specifically for apartments. Thus, this study aims to find out the problems in performance and maintenance of the existing fire detectors installed at apartment buildings which is the prerequisite process for development of intelligent fire detection system for that specific application. It is also found impossible to check whether or not the detectors installed at each apartment are in an operational state at normal times. This study finds that it is desirable to replace the slow-sensing heat detectors by a smoke and single smoke detectors which can detect a fire at its early stage in an effort to improve the problems of fire detectors installed at apartment buildings presently. Because we need to the independence fire detection system of apartment building.

In this paper, we investigated the effects of response technique which uses free tokens in the computer training for the mentally retarded person. We set wrong line entering. wrong space number entering, wrong line-type designation and wrong cell merger as the target behaviors in the research. The experiment period of the research was 36 sessions altogether, and the period was divided into four steps such as basic period I. treatment period I, basic period II, and treatment period II. We also conducted a follow up experiment to identify whether the experiment's effect is still maintained two weeks after the experiment finished. We know that the response cost technique which uses free tokens to the mentally retarded person is efficient in the computer training.

In machine translation the goal of natural language generation is to produce an target sentence transmitting the meaning of source sentence by using an parsing tree of source sentence and target expressions. It provides generator with linguistic structures, word mapping, part-of-speech, lexical information. The purpose of this study is to research the Korean Characteristics which could be used for the establishment of an algorism in speech recognition and composite sound. This is a part of realization for the plan of automatic machine translation. The stage of MT is divided into the level of morphemic, semantic analysis and syntactic construction.

The domestic market of oriental herbal cosmetics has rapidly grown in the last few years. In this study, we investigated female consumers' cosmetics-buying behavior to know their appreciation of oriental herbal cosmetics. We also tried to deduce the strategies for growth and development of the oriental herbal cosmetics market in the future. A survey was conducted with women ranging in age from 20 to 50, who resided in Seoul; a total of 400 questionnaires were distributed and then 344 copies of those. were collected and analyzed statistically. This study provides basic information about the present status of oriental herbal cosmetics market and the real state of the cosmetic consumption. The consumers needs identified in this study, provides basic data in setting a marketing strategy for the oriental herbal cosmetics market.

Purpose : Daily Q.A is the important step which must be preceded in a radiation treatment. Specially, radiation output measurement and laser alignment, SSD indicator related to a patient set-up recurrence must be confirmed for a reasonable radiation treatment. Daily Q.A proceeds correctness and a prompt way, and needs an objective measurement basis. Manufacture of the device which can facilitate confirmation of output measurement and appliances check at one time was requested. Materials and Methods : Produced the phantom formal daily check device which can confirm a lot of appliances check (output measurement and laser alignment. field size, SSD indicator) with one time of set up at a time, and measurement observed a linear accelerator (4 machine) for four months and evaluated efficiency. Results : We were able to confirm an laser alignment, field size, SSD indicator check at the same time, and out put measurement was possible with the same set up, so daily Q.A time was reduced, and we were able to confirm an objective basis about each item measurement. As a result of having measured for four months, output measurement within ${\pm}2%$, and measured laser alignment, field size, SSD indicator in range within ${\pm}1mm$. Conclusion : We can enforce output measurement and appliances check conveniently, and time was reduced and was able to raise efficiency of business. We were able to bring a cost reduction by substitution expensive commercialized equipment. Further It is necessary to makes a product as strong and slight materials, and improve convenience of use.

인터넷의 기술은 인트라넷(Intranet), 익스트라넷(Extranet)이라는 이름으로 인터넷 기술을 활용한 기업 내 또는 기업간 네트워크 구성에 관한 연구들이 활발하게 진행되고 있다. 인터넷의 개방성으로 인해서 인터넷은 보안성이 떨어지는 문제점을 가진다. 이를 극복하기 위해서 최근 많은 암호기반 보안 기술들이 개발되고 있다 대부분의 암호기반 보안 기술들은 전체네트워크 객체의 증명을 책임지는 공증 기관을 필요로 하는데, 이를 공중 사무소(Certification Authority)라 한다. 본 논문에서는 인터넷과 인트라넷의 취약한 부분을 보완하기 위한 최근의 암호기반 보안 기술과 그들 간의 상관관계를 파악한다 보안의 기초인 공증사무소의 구조 및 역할을 조사하고, 실제로 공증 사무소를 운영하기 위한 점검 사항 및 운영 규칙 등을 제시한다. 또한, 공증 사무소에 필요한 소프트웨어를 구현한다.
