Objectives: We reviewed the CAREX (CARcinogen EXposure) program designed to estimate the prevalence of occupational exposure to carcinogens and summarized the advantages and limitations of this program. Methods: All literature, including reports on CAREX and the use of CAREX, were reviewed. The keyword search term was CAREX. Additional articles were identified from references cited in articles and reviewed. Results: An exposure information system, CAREX was developed based on data from the Finnish Institute of Occupational Health of Finland and from the US. CAREX has been applied in several countries, including in the EU, in order to estimate national exposure patterns to carcinogens. The initial exposure assessment carried out through CAREX was aimed at estimating exposures over the period of 1990-1993. To estimate the number of workers exposed to carcinogens by using CAREX, reference exposure prevalence from Finland and the United States was computed, which was then reviewed and corrected by national experts. Finally the overall number of workers exposed to carcinogens can be estimated. We found that CAREX has been used in a total of 18 countries. No Asian country has used CAREX. Conclusions: CAREX can be applied not only to estimate the number of workers exposed to carcinogens in Korea, but also to identify high-risk industries with workers most exposed to carcinogens.

Open Source Software (OSS) is a new paradigm for software development. The system is based on the notion of giving software (including sources) away for free, and making money on services, customizing and maintenance. For these reasons, many software companies have considered adopting and using OSS in Software R&D. A variety of factors may influence the use of decision making of OSS. The objective of this study was to explore the significant factors affecting the use decision of OSS and the job performance of OSS usage in software R&D. A research model was suggested based on the TOE Framework and Information Systems Success Model. These findings show that technical benefits of OSS have significant effects on OSS use. The technical benefits of OSS, and organization context, in turn, have significant effects on the use of OSS. On the other hand, the technical risks of OSS and the environment context have no effects on OSS use. In addition, OSS use and user satisfaction have significant effects on the individual job performance. This research contributes towards advancing the theoretical understanding of the OSS Benefits and Performance in Software Development.

Purpose: The purpose of the study was to compare the effects of Tai Chi exercise, Tai Chi self help program, and self help management program on arthritic pain, stiffness, fatigue and difficulties in performing daily activities in patients with osteoarthritis. Method: The pre-post experimental design was utilized with convenient sampling at Public Health Centers. Total of 38 subjects agreed to participate in the study with the inclusion criteria of being diagnosed as osteoarthritis and no previous regular exercise. The 12 subjects were assigned to Tai Chi exercise group, 13 subjects to Tai Chi exercise combined with self help management program, and the other 13 to self help management program. Tai Chi exercise group performed exercise twice a week for one hour per each session. Tai Chi self help management group came to the class twice a week, one hour for Tai Chi exercise, and another hour for self help management program. The third group came to the class once a week for one hour to participate self help management program. At the completion of 6 week programs, 10 subjects from Tai Chi exercise, 9 from Tai Chi self help, another 10 from self help management groups completed the post-test measures. The data were analyzed by SPSSWIN 11.0. The homogeneity tests for three experimental groups were conducted by $X^2-test$, Fisher's exact test, Kruskal-Wallis test. The final analysis of the post-test measures was conducted by ANCOVA with fatigue, pain, stiffness, and difficulties in daily activities of the pretest measures as covariates. Results: The results were as follows. There were no significant differences in fatigue, pain, and difficulties of daily activities among three groups for the pretest measures. The score of arthritic stiffness was significantly different among groups after controlled for covariates, but the post-hoc tests showed no group differences. Conclusion: The nursing interventions applied for osteoarthritis patients have been previously tested to show the cost effectiveness of symptoms management of this population.

Temperature lapse rate within the planetary boundary layer shows a diurnal cycle with a substantial variation. The widely-used lapse rate value for the standard atmosphere may result in unaffordable errors if used in interpolating hourly temperature in complex terrain. We propose a simple method for estimating hourly lapse rate and evaluate whether this scheme is better than the conventional method using the standard lapse rate. A standard curve for lapse rate based on the diurnal course of temperature was drawn using upper air temperature for 1000hPa and 925hPa standard pressure levels. It was modulated by the hourly sky condition (amount of clouds). In order to test the reliability of this method, hourly lapse rates for the 500-600m layer over Daegwallyeong site were estimated by this method and compared with the measured values by an ultrasonic temperature profiler. Results showed the mean error $-0.0001^{\circ}C/m$ and the root mean square error $0.0024^{\circ}C/m$ for this vertical profile experiment. An additional experiment was carried out to test if this method is applicable for the mountain slope lapse rate. Hourly lapse rates for the 313-401m slope range in a complex watershed ('Hadong Watermark 2') were estimated by this method and compared with the observations. We found this method useful in describing diurnal cycle and variation of the mountain slope lapse rate over a complex terrain despite larger error compared with the vertical profile experiment.

Purpose: This study was done to provide basic data for developing nursing interventions to enhance quality of life of pediatric patients with cancer (children and adolescents) by examining the quality of life and related factors. Methods: Participants were 134; 67 pediatric patients and 67 parents. The PedsQL$^{TM}$ 3.0 Cancer Module was employed to measure quality of life in the participants. The related factors included general and clinical characteristics of the participants. Results: Mean score for quality of life in the patients was 75.07, and mean score for patient quality of life as perceived by their parents was 64.40. Among the quality of life subscales, treatment anxiety had the highest score whereas nausea had the lowest score. Mean score in adolescent patients (13-18 years of age) was 71.62, lower than the 78.04 for child patients (8-12 years of age). Regarding general and clinical characteristics of the participants, there were no significant differences in the scores. Conclusion: The results indicate that there is difference in perception of quality of life between patients and their parents, and between children and adolescents and these differences should be taken into account when planning and providing nursing care.

Background: The tuberculin skin test (TST) is the standard tool to diagnose latent tuberculosis infection (LTBI) in mass screening. The aim of this study is to find an optimal cut-off point of the TST+ rate within tuberculosis (TB) contacts to predict the active TB development among adolescents in school TB outbreaks. Methods: The Korean National Health Insurance Review and Assessment database was used to identify active TB development in relation to the initial TST (cut-off, 10 mm). The 7,475 contacts in 89 schools were divided into two groups: Incident TB group (43 schools) and no incident TB group (46 schools). LTBI treatment was initiated in 607 of the 1,761 TST+ contacts. The association with active TB progression was examined at different cut-off points of the TST+ rate. Results: The mean duration of follow-up was $3.9{\pm}0.9years$. Thirty-three contacts developed active TB during the 4,504 person-years among the TST+ contacts without LTBI treatment (n=1,154). The average TST+ rate for the incident TB group (n=43) and no incident TB group (n=46) were 31.0% and 15.5%, respectively. The TST+ rate per group was related with TB progression (odds ratio [OR], 1.025; 95% confidence interval [CI], 1.001-1.050; p=0.037). Based on the TST+ rate per group, active TB was best predicted at TST+ ${\geq}$ 16% (OR, 3.11; 95% CI, 1.29-7.51; area under curve, 0.64). Conclusion: Sixteen percent of the TST+ rate per group within the same grade students can be suggested as an optimal cut-off to predict active TB development in middle and high schools TB outbreaks.

The purpose of this comparative study is to find out women and their spouses' sexual life and the factors affecting on their sexual life after women's hysterectomy. The data were the 110 questionaires which were collected from the participants, the 55 women who had undergone a hysterectomy due to gynecologic disease or benign tumor of genital organs and their spouses from January 1, 1999 to January 30, 2002 in one general hospital located in Seoul, Korea. Questionnaires were mailed to couples, who agreed to participate on the study and self reported questionnaires returned in the pre-stamped envelopes. And personal visits were made for those couples who did not respond. Tools for Sexual life and characteristics of sexual activities were reconstituted by the author based on Kim(1996) and Chang(1988)'s tools and were reviewed by a nurse specialist. Data analysis was done by SPSS 10.0 program using frequency, percentage, mean, S.D. Pearson correlation coefficient, t-test, oneway ANOVA and multiple regression. The results of this study are as follows; 1. Of all female subjects, 80% had experienced hysterectomy below the age of 50. 2. 72.8% of female subjects and 67.3% of male subjects did not receive any sexual education & counseling before and after the surgery. More than 60% of both female and male subjects answered that it was necessary to have a sexual counseling. And 40% wanted to receive sexual counseling from a professional sexual counselor. 3. More than half of couples started their first coitus within 4 weeks after the surgery. And 88.9% of females and 85.2% of males answered that they were experiencing orgasms with their sexual relationship. 4. Influencing factors on the satisfaction level of sexual life were couple's intimacy and sexual discomfort in women and couple's intimacy and sexual knowledge in spouses. These factors explained the 33% and 24% of total variance respectively. In conclusion, the result suggests that it is necessary for couples to receive a professional sexual education and counseling to improve couples' quality of life. It is also necessary for institutions to use prepared nurses by receiving sexual counseling and education program as a professional sexual counselors or educators so as to provide individualized sexual education and counseling for their clients.
