Purpose: This study was to investigate the cancer screening rates and influence factors in island residents. Methods: The participants were 1,223 Shinan gun island residents. Data were collected using structured questionnaires from June 23th to September 8th, 2007 and analyzed using the SAS win 12.0 program. Results: The cancer screening rate was 49.9%. There were significant differences for sex, age, living with family, economic level, smoking, exercise, private health insurance, familial history, health concern. The highest practice rate was of stomach cancer (55.9%), which is gastric endoscopic exam. The most common motivation of getting a screening test was the concern of health (40.8%), and many had no recommender of the screening test (30.0%). 58.4% of the subjects were satisfied with the screeing tests and the most frequent reason of the satisfaction was 'rapid result report' (33.1%). The msot common reason of unsatisfaction was 'long waiting time' (25.7%). Most participants agreed with the necessity of cancer screening (74.9%). More than half participants said they would participate in another cancer screening tests in the future (51.9%). Private health insurance, exercise, health concern and smoking showed significant predictors (20.6%) of obtaining cancer screening. Conclusion: The results suggest that health care professionals should give more attention to help the residents obtain cancer screening tests. A further study is necessary to develop any effective intervention for people who do not practice cancer screening tests.

Purpose: This study was aimed to develop a computerized reminder system and evaluate it's effect in terms of percent age change of screening, and satisfaction. Method: It was conducted through 6 phases: Analyzing the job and defining the basic input data, developing the information system, collecting and inputting data, testing the system, working with the system, and evaluating it's effect. Participants were 787 people (female 30-69 years, and males 40-49 years) in 2 dong of Suyoung gu, Busan, who haven't had cancer screening for the stomach, breast, or cervix since Dec. 2000. There were three experimental groups: a letter; calling and calling after the letter reminder, and a non-equivalent control group. To determine whether services were obtained, a telephone survey was done after two months of follow-up. Result: A cancer screening information system with five DB modules was developed. Overall compliance with screening was not statistically significantly changedbefore and after applying computerized reminders for all three screening sites. Only 16% were satisfied with the reminder. Conclusion: This data didn't show that a reminder effort was effective of screening. However, because the evaluation interval was too short to find a difference in screening rate, we recommend additional longer prospective follow up studies.

This study was conducted to find ways to improve people's perceptions to prevent and detect breast cancer. Health belief model(HBM) was used to examine the relationship between. risk perception of breast cancer, and benefit perception, and information seeking. In addition, the role of autonomous motives was included in the model. The results shows that the more people perceived cancer as dangerous, or perceived cancer screeing as beneficial, the more likely they seek relavant health information. Also, high autonomous motives showed positive effects on info seeking. Information seeking behaviors also had a positive impact on health screening intentions.

Purpose: This study aimed to identify current quality control (QC) practices of primary care clinics participating in the National Cancer Screening Program (NCSP) in Korea. Methods: A nationwide survey using a structured questionnaire was conducted among the primary care clinics participating in the NCSP, which were selected by a proportionate stratified sampling. The questionnaire consisted of general information about the responding clinics and the scope of QC activities undertaken. A total of 360 clinics responded and the set of data was then analyzed with Chi-square test and multivariable logistic regression analysis. Results: Among 360 respondents, 332 (92%) reported that they were involved in the QC activities. Most frequently performed QC activities were 'maintenance of facility and instruments' (89%) and 'staff training' (85%). The analysis revealed, with statistical significance (p<.05), that there was an association between certain characteristics of the clinics and the scope of QC activities. These findings also indicated that the diversity of QC practices varies according to the size of the clinics. The clinics screening more types of cancer, those with more screenees, and those with more employees were more likely to implement various QC activities including 'maintenance of facility and instruments', 'external quality control', and 'management of screening data'. Conclusion: To our knowledge, this is the first study to investigate the current status of QC activities conducted among primary care clinics participating in the NCSP. The results of this survey can be used as a basis for further development of policies on quality management of small- and medium-sized primary care clinics in Korea. However, further studies encompassing various aspects of QC activities and management of primary care clinics are needed to assess the current situation in a concise manner.

사람 성장호르몬 수용체(hGHR) cDNA는 PCR방법에 의하여 fagment로서 보고되어진 바 있으나, liver cDNA로 부터 전장을 cloning한 보고는 없는 실정으로 본 연구에서는 기능을 가진 약 4.6kbp의 cDNA hGHR을 cloning 하는데 성공하였다. 먼저 cloning하기 위하여 human liver mRNA와 human breast cancer tissue로부터 회수한 mRNA를 RT-PCR방법에 의하여 human cDNA library와 cloning에 필요한 probe를 제작하였다. human library mRNA는 GT-PCR방법에 의하여 증폭하여 증폭되어진 산물은 λZAP Vector를 이용하여 cDNA library를 구축하였고,screeing을 위하여 임 보고 되어진 hGHR fragment native sequence를 기초로 N-terminal부분의 primer를 설계하여 950bp의 probe를 얻는데 성공하였다. 이 probe를 이용하여 준비된 human liver cDNA library로부터 2.5$\times$10 6개의 plaque로부터 6개의 positive clone을 획득하였고, 이들중 poly Asignal인 "AATAAA"를 포함하고 있는 가장 긴 약 3.8kbp의 clone을 sequencing한 결과 open reading frame을 포함하고 있었으나, 5'부분의 결손되어 있었다. 그리하여 이 부분은 human breast cancer tissue로 부터 회수한 mRNA를 RT-PCR에 의하여 증폭하였고, sequencing결과 이미 보고되어진 native hGHR와 비교한 결과 하나의 nucleotide가 silent mutation으로 판명되었다.한편 human liver cDNA library로부터 cloning한 3.8cp의 positive clone의 5'end의 결손된 부분에 silent mutation된 PCR 산물을 연결함으로써 native hGHR와 유사한 cDNA hGHR subcloning에 성공하였다. 이러한 cDNA hGHR의 clone이 function을 가지고 있는지를 검토하기 위하여 eukaryotic 발현 vector인 pCXN2에 의거 ligation한 후 chinese hamster ovary cell[CHO-KI]에 transfect를 실시하였다. Dexamethasone은 첨가하지 않고 hGH만의 존재하에서 이들 cell을 배양시키고 cell menbrane에서 발현 여부를 판정키 위하여 hGHR monocloual antibody를 사용하여 flow cytometery해석을 실시하는 한편 125I-hGH binding assay에 의하여 hGH binding activity를 측정하였다. 최종적으로 GH signal transduction의 target genedf으로 알려져 있는 serine protease inhibitor 2.1(Spi 2.1) gene의 promotor activity를 검토한 결과 hGHR을 transfect한 CHO Cell에 있어서 hGH의 농도에 의존적으로 증가되었다. 따라서 본 실험에서 cloning한 cDNA hGHR는 native hGHR와 같은 기능을 가지는 것으로 판명되었다.것으로 판명되었다.

This study was conducted to estimate the prevalence rate of cervical cancer and to investigate its risk factors. 5,417 asymptomatic married women were screened from March, 1984 to December, 1990 in Taegu city. Of 5,417 examinees, 3,817 (70.46%) were normal, 1,542 (28.7%) showed inflammatory change, 51 (0.94%) were dysplasia and 7 (0.13%) were carcinoma in situ or invasive carcinomas. The prevalence of abnormal finding (dysplasia, carcinoma in situ or invasive carcinoma) was 1,070 per 100,000 population. The prevalence of dysplasia was 940 per 100,000 and that of carcinoma in situ or invasive carcinoma was 130 per 100,000. Age-adjusted prevalence rate for abnormal finding adjusted with standard population of Taegu city was estimated to be 850 per 100,000. The prevalence of cervical cancer was significantly increased with age (P<0.05). The prevalence of cervical cancer was significantly decreased with age at marriage and educational level (P<0.05). The history of induced abortion and the number of pregnancies were significantly associated with the prevalence of cervical cancer (p<0.05), whereas, the number of parity was not. Age at marriage was significantly associated with the prevalence of cervical cancer after stratification by age (p<0.05). However, the level of education, parity, induced abortion, number of pregnancies were not significant. Inflammation and human papiloma virus infection were associated with cervical cancer with odds ratio of 13.48 (95% confidence interval $7.80{\sim}23.40$) and 474.29 (95% confidence interval $196.80{\sim}1143.10$), respectively. In conclusion, for early detection of cervical cancer it should be recommended to perform mass cytological screening. In particular, regular and periodic cytologic screening, starting at age 25, for cervical cancer should be recommended for those women who have frequent cervical inflammation and for those women married before age of 20.
