김학희 가톨릭대학교 가톨릭암센터 2000 암심포지움 Vol.- No.1
유방암은 여성 3대 암 중 하나로 조기 진단만이 효과적인 치료와 mortality를 줄일 수 있는 치선의 방법이다. 단순유방촬영술은 50세 이상의 연령에서 morality를 30%, 40∼50세 여성에서 17% 정도 낮추었다. 하지만 많은 여성이 치밀한 방사 비투과성의 유방조직을 가지고 있기 때문에 진단에 어려움이 많으며, 단순유방촬영술에서 발견된 병소의 75%가 양성으로 조직검사 등을 포함한 많은 불필요한 검사를 시행하게 되고, 유방암의 약 15∼20%를 놓치게 된다. 따라서 최근 유방암의 스크리닝과 진단을 위해 새로운 방법들이 개발 중이거나 시험 중에 있다. 이들 방법들의 가치평가는 스크리닝(detection)과 진단적 가치를 나누어서 생각해야 한다. 스크리닝은 건강하고 증상이 없는 여성에서 주기적인 검사를 통해 조기에 유방암을 발견하기 위한 것이고 반면에 진단적 평가는 양성과 악성질환을 감별하는 것이 목적이다. 그러나 스크리닝과 진단 모두에 효과적인 방법이 가장 이상적임은 당연한 것이다. 이러한 병소의 발견과 진단 외에 다른 중요한 요소는 유방암의 치료방침을 위한 종양 범위의 결정, staging, 예후의 펑가, 재발암의 발견 등이다 이러한 평가기준을 중심으로 최근 개발되었거나 개발중인 영상방법들에 대하여 review 하고자 한다.

This is a nonequivalent control group pretest-posttest design in quasi experimental basis to assess how the radiant warmer application influences on temperature changes in neonates. The subjects were selected among the NSVD neonates who was born in E Medical University Hospital with the weight 2800~3800 gm, gestational period over 37 weeks, 5 min. Apgar score over 8, and with no congenital malformation. The experimental group of 30 neonates were placed under radiant warmer for 1 hour and control group of 30 neonates were not placed under radiant warmer. Data were collected between December 1st, 2000 to December 31st, 2000 and were analyzed using t-test, x^(2)-test, means, standard deviation, paired t-test. The results of this study were summarized as follows ; 1. The experimental group who were placed under radiant warmer for 1 hour showed statistically significant less temperature loss than control group(p=.000). 2. The experimental group who were placed under radiant warmer for 1 hour showed statistically significant shorter normal body temperature recovering time than control group(p=.013). Therefore it can be concluded that 1 hour radiant warmer application after birth were an effective nursing intervention strategies in thermoregulation of neonates after birth.

전산화 단층촬영을 이용한 하악관의 해부학적 위치에 관한 연구
김학희,조병욱,Gim, Hag-Houey,Cho, Byoung-Ouck 대한악안면성형재건외과학회 1992 Maxillofacial Plastic Reconstructive Surgery Vol.14 No.1
This study was performed to define the anatomical position of the mandibular canal and the findings during the sagittal split ramus osteotomy of the mandible. The mandibles of 20 adult Korean were used. The dimension of mandibular canal from the mandibular foramen to the 1st molar was measured at 4 specific coronal-sectional location by CT scan. The results were as follows ; 1. The distance from the mandibular canal to the medial aspect of the buccal cortical plate was greatest($4.5{\pm}1.1mm$) at 2nd molar area and was not significantly greater than at any other section. 2. Buccal cortex was thickest($3.8{\pm}0.9mm$) at 2nd molar and thinnest ($2.5{\pm}0.3mm$) mandibular foramen um 3. The distance from the mandibular canal to the medial aspect of the lingual cortical plate was not significant at any sections. 4. The distance from the mandible canal to the inferior border of mandible was greatest at the mandibular foramen($20.7{\pm}3.9mm$). The canal was located more closely to the inferior border at 1st, 2nd molar area 5. The diameter of the mandibular canal was between $2.5{\pm}0.3mm$ and $2.8{\pm}0.6mm$. 6. The total mandibular thickness was greatest($21.1{\pm}2.6mm$) at 2nd molar area and narrowest($17.2{\pm}3.2mm$) at mandibular foramen area.

Activated carbons were successfully prepared from coffee waste by chemical activation with Phosphoric acid. Coffee waste was roasted at 300∼400℃. Carbonization was carried out at 750℃, 1hr. Chemical activation was carried out by using phosphoric acid as an activation agent at 700℃, 2hr. The concentration of Phosphoric acid was in the range of 30% ∼50%. N_2-BET surface area of activated coffee char prepared by chemical activation was measured as about 975∼1154㎡/g. Adsorption concentration of copper(II) by coffee activated carbon was found in the range of 340ppm∼238ppm. Structural change of pore surface was observed by Scanning Electron Microscopy(SEM).

공공기관 인터넷 사이트의 행정서비스 품질 평가에 관한 연구 - 오프라인/온라인 비교분석
김학희,김경준,박정희 한국디지털정책학회 2007 디지털융복합연구 Vol.5 No.1
Due to the development of Internet and networking technologies, it is much more easier to get in touch with public service through the web services such as tax, travel information, getting a job, etc. In order to measure the quality of official government web sites, we are to test the difference between the web quality of the government sites and the offline feature of the same official service by means of customer perspectives. The resulting of this study show that the quality of official web site has been improved so far though such areas as privacy, security needed to be updated. Especially the web interface or contact point of the digital media should be reflected customer's need so that the online materials may be quickly updated according to the request of client's.
