광역 교통망 및 통신기술의 발전에 따라 광역경제권의 활성화를 위한 협력체계의 중요성이 날로 증대되고 있다. 이에 본 연구는 동남권 광역경제권을 대상으로 GIS 기반의 산업체 정보 공유를 목적으로 동남권 산업체 정보시스템을 구축하였다. 동남권의 경우 제조업 중심의 산업 집적지로서 행정경계를 넘어 산업체간의 근접성과 연결성을 고려한 효율적인 산업 클러스터 및 협력체계 운영이 요구된다. 정보시스템의 DB 구축을 위해 부산, 울산, 경남에서 구축되어진 산업체 DB를 활용하여 정보시스템을 구축한 바, 각 지자체간 데이터의 불일치와 GIS기반의 위치정보 미흡으로 인한 여러 가지 문제점을 발견하였다. 이의 해결을 위해서는 수집 및 배포, 활용과정을 고려한 표준화가 시급한 것으로 분석되었다. 본 연구는 산업체 정보의 공간정보화를 위해 지적도와 수치지도를 활용하여 웹상에서 관리자-사용자 쌍방향간의 정보생성 및 단계별 접근이 가능한 2-way 방식의 산업체 정보시스템을 구축하였다. 본 연구의 결과는 동남권 산업육성을 위한 협력체계 및 공동대응을 위한 산업체 정보 공유체계의 기초적 틀을 제공하였다는 데 그 의의가 있다고 하겠다. Following the technology developments of traffic network and communication for the wide area, the importance of the cooperation system to vitalize the wide area economy is increasing. Therefore, in this study, DongNam Kwon industry information system is established for the industrial information sharing based on GIS in the DongNam Kwon wide area economy. The DongNam Kwon is an industrial integration area centered with the manufacturing so that the operation of effective industrial cluster and cooperation systems are required across the administrational boundaries. To establish the database of the information, the information system was established utilizing already established industrial databases in Busan, Ulsan and Gyeongnam. But, various issues caused by the discordances among the data of each local government and the insufficiency of GIS based location information have been found. According to the analysis, the standardization considering the courses of collection, distributions and utilization are required immediately to solve the issues. This study establishes an 2-way industrial information system enabling the information creation and the phased approach between the administrator and the user in the bi-directions on the web by utilizing cadastral and numerical maps. The result of this study would have a meaning in providing a fundamental frame for cooperative responses and cooperation system for DongNam Kwon``s industrial promotion using industrial information sharing.

A desirability function approach to a multiresponse problem is proposed considering process parameter fluctuation which may amplify the variance of response. It is called POE(propagation of error), which is defined as the standard deviation of the transmitted variability in the response as a function of process parameters. In order to obtain more robust process parameter setting, a new desirability function is proposed by considering POE as well as distance-to-target of response and variance. The proposed method is illustrated using a rubber product case in Ribeiro et al. (2000).

권성준,최갑림,임성훈,김광원 대한치과교정학회 2004 대한치과교정학회지 Vol.34 No.5

일반인들이 선호하는 상순과 턱의 수직 비율(Sn-Stm/Stm-Me')을 알아보기 위해 남녀 각 2명의 연조직 측모(profile)를 상순과 턱의 수직비율에 따라 상악의 변화없이 하악만을 변화시켜 1/1.8, 1/1.9, 1/2.0, 1/2.1, 1/2.2 비율의 5개의 측모 사진을 만들어 치과의사 44명(남자 22명. 여자 22명)과 일반인 430명(남자 303명, 여자 127명)을 대상으로 하여 설문조사를 통하여 선호도를 조사하여 다음과 같은 결과를 얻었다. 대상의 가장 선호하는 안모에 대한 성별간의 선호도 차이는 통계적으로 유의하지 않았다. 대상의 가장 선호하는 안모에 대한 치과의사와 일반인 집단간의 선호도 차이는 통계적으로 유의하지 않았다. 남녀 측모 모두에서 가장 선호하는 측모의 상순과 턱의 비율은 1/1.9이었으며 가장 선호하지 않는 비율은 1/2.2 로 나타났다. 이상의 결과를 종합하여 볼 때, 이전의 연구 비해 상순과 턱의 수직비율에서 턱의 비율이 다소 작은 측모, 즉 상순과 턱의 수직 비율이 1/1.9인 안모를 가장 선호하는 것으로 나타났다. The purpose of this study was to investigate the preference of Vertical Lip-Chin Ratio (= Sn-Stm /Stm-Me' hereafter VLCR) in Koreans. The assessors consisted of 44 dentists (male 22, female 22) and 430 lay persons (male 303, female 127). The survey was performed using a questionnaire asking the order of preference. The profiles presented in the questionnaire were based on the profiles of two males and two females, each morphed according to the VLCRs of 1/1.8, 1/1.9, 1/2.0, 1/2.1, 1/2.2. The results were as follows: The difference between males and females, and the difference between dentists and lay persons in the preference of VLCR were not statistically apparent. The most preferred VLCR was 1/1.9, and the least preferred VLCR was 1/2.2. These results indicate that the preferred VLCR is smaller than the previously reported VLCR ratios based, on the cephalometric evaluation of samples with favorable facial esthetics.

Adsoprtion characteristics of Cu(II) and Zn(II) heavy metal ions onto the Acrylamide-immobilized Ulva pertusa, a living algae of the castern coastal area, was examined in this work. Much amounts of heavy metal ions were adsorbed onto the Acrylamide-immobilized Ulva pertusa than the bare Ulva pertusa. It was also observed that Zu(II) was more readily adsorbed on the algae than Cu(II). The adsorption, but those were high dependent on pH value at high adsorbent concentration. The adsorption amounts of heavy metal ions were in the following order; pH 10.5>8.5>7.0>5.5>3.5. The maximun adsorption amounts of Cu(II) and Zu(II) onto 1g of Acrylamide-immobilized Uiva pertusa were 7.6㎎ and 8.1㎎, respectively. It was found that recovery yields of Cu(II) and Zn(II) ions were in the range of 36.1-64.8% and 32.1-63.8% depending on the pH level. In the heavy metal ions was well matched with the Freundlich adsorption isotherm.

To test the protective effect of herbal medicine on myocardial damage against adriamycin-induced myocardiotoxicity, cytotoxicity of adriamycin was examined using MTT assay and protective effect of herbal medicine in the presence of water extract of Gamdu-tang, Gamigamdu-tang, or single constituents of these prescriptions was examined using counting of beating rate. The results of these experiments were obtained as follows : Adriamycin resulted in a decrease in viability and beating rate in cultured myocardial cells. Gamdu-tang water extract shows effects of protection from the cardiocyte toxicityinduced by adriamycin treatment such as increases beating rate. Gamigamdu-tang water extract shows the similar protective evvect as shown in gamdu-tang treatment on the decreasing of beating rate induced by adriamycin. Radix Glycyrrhizae, Semen Glycine, and Folium Phyllostachyos water extract shows a significant effect of protection for cardiotoxicity induced by adriamycin in cultured myocardial cells. These results show that adriamycin elicits toxic effects in cultured myocardial cells derived from neonatal mouse, and suggest teat water extract of gamdu-tang, gamigamdu-tang, Radix Glycyrrhizae, Semen Glycine, or Folium Phyllostachyos is very effective in the prevention of adriamycin-induced cardiotoxicity/

광섬유 ROTDR(Rayleigh optical time domain reflectometry) 센서를 이용하여 중요 보안 대상체인 사회기반시설물에 침투하는 침입자의 위치와 무게 정도를 탐지할 수 있는 기초 연구를 수행하였다. 넓은 면적을 감지할 수 있는 매설형 광섬유 센서탐지판을 제작하고, 인가된 침입물체의 위치와 무게에 따른 신호특성을 고찰하였다. ROTDR 센서는 펄스 폭이 30 ㎱이고, 광섬유의 길이는 10㎞ 이상이다. 위치탐지오차는 약 3m 이내였으며, 무게에 따른 탐지능력은 20kgf, 40kgf, 60kgf의 세단계를 구분할 수 있음을 알 수 있었다. A detection technique is studied to determine the location and the weight of an intruder into infrasturcture using fiber optic ROTDR(Rayleigh optical time domain reflectometry) sensor. Fiber optic sensing plates buried in sand are prepared to measure the intruder effects. The signal of ROTDR was analyzed to confirm the detection performance. The constructed ROTDR system could be used up to 12 ㎞ at the pulse width of 30 ㎱. The location error was less than 3 m and the weight could be detected into three levels of grade, such as 20 kgf, 40 kgf and 60 kgf.
