This study was designed to investigate the workers' exposure level to electromagnetic field(EMF) in accordance with the VDT arrangement in the work place and distance from VDT. Author compared the exposure strength of EMF in line group(workers exposed to EMF from both front and back side) and in shielding group(workers exposed to EMF exclusively from front side). The levels of EMF at 30cm and 50cm from front side and at 30cm from back side of VDT were also measured. The result were as follows: 1. Mean distance between a monitor and a worker in shielding group ($47.7{\pm}8.7cm$) significantly longer than that in line group($44.3{\pm}7.2cm$). Strength of EMF in shielding group [$1.3{\pm}0.7V/m$ (electric field) and $18.2{\pm}11.5mA/m$ (magnetic field) were lower than in line group [$1.4{\pm}0.6V/m$ and $26.6{\pm}11.6mA/m$, respectively] at the workers' position. 2. The strength of EMF was decreased with the distance from VDT. The strength at 70cm from VDT was nearly the same as the background strength in the ordinary office rooms. 3. Working distance from 9 inch monitor was significantly shorter than that from 14 inch and wider sized monitors. 4. The strength of EMF in extremely low frequency spectrum of color monitors was higher then that of black and white monitor. 5. Metal coated filters significantly decreased the electric field strength of EMF when earth line was connected. Metallic shield was effectively decreased the EMF strength from VDT, but wooden shield was not. From the above results, line type arrangement of VDT in the work place using metallic shield at the back side of VDT, and metal coated filter to monitor with application of earth line were recommended. It is also recommended to maintain workers position to be 60cm or more distance from monitor and 140cm or more between VDTs for minimizing workers' exposure to EMF.

조선시대 후기 고위관료였던 한필교(1807~1878)의 화첩 "숙천제아도(宿踐諸衙圖)"를 통해본 중앙관아의 공간구조와 조경기법에 관한 연구결과는 다음과 같다. '사방전도묘법(四方顚倒描法)'으로 그려진 "숙천제아도"는 조선시대 중앙 및 지방관아의 공간구조와 문화경관 특성을 파악할 수 있는 독보적 실증사료로서 가치를 지닌다. 조선의 정궁(경복궁) 광화문 밖 육조(六曹)거리에 자리 잡은 중앙관아는 장방형 부지에 중심시설(당상대청)과 부속 건물이 서열에 따라 상 하 또는 좌 우로 분산되는 구조인데, 주 건물은 남향으로 배치되었으며, 행정편의와 환경성, 그리고 유교적 규범성의 실천 등 위계적 토지이용 체계를 반영하고 있다. 관리들의 직무공간인 당상대청과 향청 등 주요건물은 너른 네모꼴 앞마당을 두어 실용성 위주의 중정(中庭)을 구축하였고, 중심건물(당상대청)은 연못과 정자 등 의미경관을 반영한 후원을 가꾸었다. 특히, 토지이용에 있어서 적극적 공간과 소극적 공간이 교차 반복<동(動)과 정(靜), 채(棟)와 마당(庭), 정(庭)과 원(園)>되는 중용적 사유체계를 보여준다. 중앙관아조경의 특징은 실용적 성격의 앞마당과 경관적 측면이 강조된 뒤뜰을 연계시킨 외부공간의 확장성(前庭+棟+後園), 그리고 환경쾌적성, 경관성, 상징성, 방화용수 목적 등이 복합적으로 고려된 수경시설(方池)의 도입을 들 수 있다. 또한 휴양과 심신수양을 도모하기 위한 정자의 도입 및 후원의 발달, 정심수(庭心樹 : 연, 버드나무, 소나무, 느티나무 등)로서의 의미부여와 제한적인 식물도입, 그리고 심미성, 관념성, 실용적 가치 등을 중시한 환경설계기법이 추출된다. 이러한 중앙관아의 조경기법은 우리나라 궁궐, 사찰, 서원, 상류주택 등 전통공간에서 유사하게 추출되는 보편성이자 특수성이라 하겠다.

A survey of radon concentrations in both indoor and outdoor atmospheres was carried out using EIRM and Cup Monitor for the period of February 1996 to March 1997. EIRM were used to measure the indoor and outdoor radon concentration at five major cities university. Cup Monitor were also used to measure the indoor radon concentrations at shopping store, office building, apartment, hospital and house in Seoul. The mean indoor and outdoor radon concentrations at the five major cities(Seoul, Daegu, Daejon, Cwangiu and Busan) were 24.1 Bq/m$^3$and 8.62 Bq/m$^3$, respectively. The ratio of indoor to outdoor radon concentrations ranged front 1.7 to 3.9. Inspection of its seasonal distribute pattern indicates the enhancement during winter relative to summer, consistently for both indoor and outdoor air. The results of the survey showed that the concentrations in basements were clearly higher than those in usual living/working places.

This study is performed the design and production of the real hotel uniforms around the actual case. The purpose of the study is to research and develop the uniform design which is partially utilized for image integration. After reviewing and making up a theoretical background of general hotel uniforms, we designed I hotel's uniforms based on the uniform design process. Research Scope of uniform design is up to the development of it for practicians who have many opportunities to meet customers directly at front desk, banquet reservation office and restaurant. Based on logo of company C.I.(Corporate Identity) and symbol colors, the concept and an illustration according with I hotel are drawn up. Also design is planed and a real is produced. This like objective design development becomes the basis for building a uniform image suitable for C.I.(Corporate Identity) of hotel I and realizing a positive service. Also this study associated with the company would help the design development of corporate uniform.

Recently, business application vendors have responded to customer demand with several technological and organizational changes for reflecting network-oriented process flow with electronic communication and expanding their market. In organizational changes. Vendors are adding new functionality to their core offerings through mergers and acquisitions, or by partnering with front-office operation and SCM vendors. And technological changes are embracing the development of component-based application and middleware technology to be possible with integration of their function modules. We will present the design and development process of component-based SCM system to be integrated with heterogeneous ERP under implementation. Especially, we survey and analyze the technology related with CBD(Component-Based Development) to be adapted this research - component's design and methodology, the interface for component integration, middleware's development methodology of Enterprise Middleware vendo to bundle various types of middleware into a single package product with easy-to-use interface.

In the fibre to the home (FTTH) era, it is expected that broadband network provisioning will require thousands of optical fibres to be accommodated in a central office for optical access networks. An optical fibre line testing system could be used to reduce maintenance costs and improve service availability depending on the PON's element manager capabilities and the maintenance procedures adopted by the network supplier. When monitoring optical fibres transmitting communication lights, a wavelength of 1625 nm is used for maintenance testing. The splitter installed optical filters allow the communication light to pass but that cut off the test light in the front of optical line terminals (OLTs) and optical network terminals (ONTs). In the economic point of view, We design new planer lightwave circuit splitter embedded filtter and study it optical property.

A survey was performed to provide current information on professional catering companies. Twenty-three catering companies out of thirty-eight(60% recovery) responded the survey for December in 1998. Foodservice establishments managed by 16 small-middle sized catering companies provided an average of 11,200 meals daily, while those managed by major and small-middle sized catering companies were mainly office(72.2%, 57.1%) and school foodservice(15.2%, 26%). The rates of sales of major catering companies and small-middle sized catering companies increased 24%, 30% respectively in 1998. Self-evaluation in catering companies was conducted for sanitary management. Unsatisfactory results from self evaluation were found in three categories, such as, measurement of internal temperature of food materials at reception, ventilation system in the working area, and hand-washing stations with equipment cleaning and sanitizing facilities in front of the working area. Most catering companies expressed a willingness to apply the Hazard Analysis Critical Control Point (HACCP) system from this survey. $\ulcorner$Professional catering business has arisen as an area requiring more consideration and further study for the production of a safe food.$\lrcorner$
