This study aims to investigate the use state of the health service computerization system in the occupational nursing field and the occupational nursers' satisfaction level, and provide basic data to promote the development of the health service computerization system for the nursing field. For this study, a questionnaire was provided to 118 occupational nurses who belong to Busan and Gyeongnam branches of KAOHN(Korean Association of Occupational Health Nurses) for 2 months (from Dec. 1, 2002 to Jan. 31, 2003). A tool of Choi Yong-Heui(2000) was used to investigate the satisfaction level of using the health service computerization system. The collected materials were analyzed in real number and percentage, average and standard deviation, t-test and ANOVA by using the SPSS WIN 10.0 program. This study is summarized as follows: 1. The average age was $31.99{\pm}5.58$ old in this study. The married were 54.2%. Participants who graduated from a junior college was 76.9%. The average service period was $4.48{\pm}4.68$ years. In service types, 79.7% of participants served in a health care center. The average service period was $3.22{\pm}2.89$ years. The service place which had 1000 workers or more was 35.6%. 2. Only 20.3% of participants in this study had a computer use education. 3. The field who participants used mostly was communication/internet, $3.29{\pm}.85$ hours in average. 4. 97.1% of occupational fields had computers and peripheral devices: 71.4% in pentium computer, 42.8% in the hard disk capacity of 20-29GB, 60.0% in 15 inch monitors, 86.2% in printers, 18.1% in digital cameras, 12.4% in LAN, and 9.5% in scanners. 80.1% of the occupational fields which were objects of study could use communication. 5. The occupational fields which did not introduced the health service computerization system were 62.8%. The main cause was attributable to entrepreneurs' insufficient recognition 66.6%. 51.5% of the entrepreneurs did not have an introduction plan. 37.2% of participating companies had the health service computerization system. 56.4% of them introduced it since the year 2000. 81.6% of the introduction motivation aimed to the efficiency of health service. The most issue upon introduction was insufficient understanding of a person in charge - 25.6%. The in-house development of the system covered 56.4%. 61.5% of the participants accepted their demands from the first stage of development. The direct effect of computerization showed the increase of 25.9% in the quickness and continuity of service treatment, and 25.9% in the serviceability of statistical treatment. 6. 22.0% of the participants had a computerization system use education. 69.2% of them had a in-house education. An educational method by nurses who used the computerization system was 76.9%. 92.3% of the education was helpful for practical duties. 7. An analysis of the computer use by health service fields showed that the medicine management in a health management field was 15.9%. the work environment measuring management in a work environment filed was 32.9%. the employment. general and special examination management in a heal th management field was 61.1 %. the various reports management in an administrative field was 64%. the health education data preparation management in an educational field was 58.0%. and the medicine and expendables management in an equipment management field was 51.6%. An analysis of the computerization system use showed that the various statistical data manage in a health management field was 13.0%. the work environment measuring management in a health management field was 34.8%. the personal disease management in a health management field was 51.9%. the heal education data preparation management in an educational field was 54.5%. and the equipment management of health care centers in an equipment management field was 52.6%. 8. 31.6% of the participants wanted that health service computerization system would include the generals of health services. 42.4% of the participants thought that first of all. the aggressive interest and investment of employers were required to build the health service computerization system. 9. The participants' satisfaction level on the computerization system use was $3.51{\pm}.57$ points. An analysis by each factor showed $3.62{\pm}.68$ points in a service change factor. $3.15{\pm}.63$ points in a computer program use factor, and $3.45{\pm}.71$ points in a continuous computerization use factor. 10. An analysis of the computerization system use by general characteristics of participants showed that the married (p = .022) had the satisfaction level higher than the unmarried. 11. The satisfaction level of the computerization system use by participants' computer use ability tended to be higher in proportion to the increase of computer use abilities in spreadsheet (F=2.606. p=.048). presentation (F=3.62. p=.012) and communication/internet(F=2.885. p=.0321. Based on the study results mentioned above. I will suggest as follows : The nationwide enlargement and repetition study is required for occupational nurses who serve in occupational nursing fields. The computerization system in a health service field is inferior comparing with other fields. The computerization system standard by business types and characteristics should be prepared through employers's aggressive participation and national support. Therefore various statistical data which occurs in occupational fields will be managed systematically and efficiently. A regular and systematic computer education plan for occupational nurses in charge of health services in the filed is urgently required to efficiently manage and improve the health of on-site workers.

Extremely low frequency electro magnetic fields (EMFs) have been classified as possibly carcinogenic to humans by the International Agency for Research on Cancer. An increased number of chromosomal alterations in peripheral lymphocytes are correlated with elevated incidence of cancer. The aim of the present study was to assess occupationally induced chromosomal damage in EMF workers exposed to low levels of radiation. We used conventional metaphase chromosome aberration (CA) analysis and the micronucleus (MN) assay as biological indicators of non ionizing radiation exposure. In the present study totally 70 subjects were selected including 50 exposed and 20 controls. Informed written consent was obtained from all participants and the study was performed in accordance with the Declaration of Helsinki and the approval of the local ethical committee. A higher degree of CA and MN was observed in exposed subjects compared to controls, the frequency of CA being significantly enhanced with long years of exposure (P<0.05). Moreover increase in CA and MN with age was noted in both exposed subjects and controls, but was significantly greater in the former. The results of this study demonstrated that a significant induction of cytogenetic damage in peripheral lymphocytes of workers occupationally exposed to EMFs in electric transformer and distribution stations. In conclusion, our findings suggest that EMFs possess genotoxic capability, as measured by CA and MN assays; CA analysis appeared more sensitive than other cytogenetic end-points. It can be concluded that chronic occupational exposure to EMFs may lead to an increased risk of genetic damage among electrical workers.

This study was designed to explore how learners' participation develop if provided with opportunities for various scientific practices and experiences in writing science magazine articles as an extra-curricular club activity and what factors facilitate these participation development. Data from participant observations, in-depth interviews with students, and documents were used to extract the common characteristics of the practices. The learners' development was categorized into 3 stages in terms of participation in the community of practice: peripheral participation, transitional participation, and full participation. As participation develops, situational interest developed to individual interests and value attachment. Students sought to get ideas from every day life, and finally, in the stage of full participation, advances in writing showed the characteristics of knowledge transformation. Best of all, the participants enjoyed and valued their participation showing identities as journalists. The nature of science magazine article, external scaffolding, and internalization through enjoyment and value attachment appeared to be decisive factors that facilitate the development of participation. Student's enculturation of writing for learning offers a possibility that continue to do so, even after they have left formal schooling and make a basis for lifelong learning.

There has been a claim that Interaction between the cerebral hemispheres could reduce the effect interfering information (Weissman & Banich, 1999). We ran three experiments to show that between-hemisphere separation of target and distractor could be more effective for reducing interference than Interaction between the hemispheres. In experiment 1, a colored box and a rotor name were presented to a single or to separate hemispheres. In experiment 2 and 3, a colored circle (distractor) was presented along with a colored box and a color name which was always printed in black. In experiment 3, a peripheral cue was presented either to the target location(66.7%) or to the distractor location(33.3%) Immediately before the presentation of stimuli. In all experiments, the participants were asked to deride whether the moaning of the color matched the rotor of the box, Ignoring the printed rotor of the word(Exp. 1), or the color of the circle(Exp. 2 & 3). There were three renditions of distractor (congruent, incongruent, and neutral) and two conditions of matching (between- and within-hemisphere matching). If interhemispheric interaction were effective for interference reduction, there should be a decrease in the interference in the between-hemisphere compared to the within-hemisphere matching condition. The results showed that there was no difference in the interference between the two matching conditions in Exp 1. In Exp 2 and in the target-cue renditions of Exp. 3, the amount of interference in the between-hemisphere condition was greater than that in the within-hemisphere condition. These findings are consistent with what we have previously reported (Sohn et al., 1996, Sohn & Lee, 2003). However, when the distractor was precued in Exp. 3, the amount of interference did not differ between the two marching conditions. These results suggest that between-hemisphere separation of target and distractor can be more effective for reducing response interference than interhemispheric communication. It implies a possible role of an interhemispheric shielding mechanism (Merola & Liederman, 1985) to prevent the transfer of task-irrelevant, harmful information across the hemispheres.

Psychophysical experiment was performed to investigate how audio-visual spatial disparity affects on perceptual space in peripheral vision. In the experiment, participants were exposed to two stimuli of vision and sound which comes simultaneously from different directions, respectively. The visual stimulus was implemented by 7 white LEDs which were located at an equal distance with 7 different angles of $-70^{\circ}$, $-40^{\circ}$, $-20^{\circ}$, $0^{\circ}$, $20^{\circ}$, $40^{\circ}$, and $70^{\circ}$ from the right front. Those audial stimuli were also implemented by loudspeakers which were placed at 9 different directions equally spaced by $5^{\circ}$ ranged from $-20^{\circ}$ to $20^{\circ}$. Each participant then evaluated spatial disparity between visual and audial stimuli with 5 levels of response, in which the higher level indicates the larger gap. When the visual stimulus is applied from the right, the results show that the response level gets higher for a larger angle between visual and auditory stimuli. A similar tendency for the visual stimulus with $0^{\circ}$ orientation was also be observed. On the other hand, when the visual stimulus is applied from the left, the response level gets lower for the larger angle.

Although there ate many studies on cross-cultural comparison of advertising appeals, very little is known about how receivers from different cultures process visual images in global advertising. The purpose of this study is to examine how cultural differences between East Asians and Westerners influence the cognitive process of visual images from standardized global advertising by employing the Nisbett's framework of holistic/analytic thought. Nisbett contends that East Asian tend to attend to the context and the relations between objects and contexts as holistic thinkers while Americans tend to see the worlds analytically. The results of a experimental study conducted using 80 subjects from Korea and the United States suggest that Korean participants are more likely to mention relatively peripheral, nonsalient, or background information than are American participants. Thus, this study support the Nisbett's notion that East Asians are more sensitive to contextual information than are Westerners and challenge the belief that standardized visual images are part of a "universal language".

Background: Hepatitis B virus (HBV) is a major risk factor for hepatocellular carcinoma (HCC). Cytokines play an important role in the regulation of immune responses and defense against viral infections. Human interleukin 6 (IL6) is a multifunctional cytokine that participates in these processes. Objective: The aim of this study was to assess the IL6-174 gene polymorphism in patients with chronic hepatitis B virus (HBV) infection as compared with healthy controls in an Iranian population. Materials and Methods: Totals of 297 HBV patients and 368 control individuals were evaluated. Genomic DNA was extracted from peripheral blood and the SSP-PCR (sequence specific primer-polymerase chain reaction) method was applied for genotyping. Results: The frequencies of genotypes C/C, G/G and C/G in HBV cases were 4.7%, 34.3%, 60.9% and in controls were 12.8%, 39.7% and 47.6%, respectively. The frequencies of G and C allele in patients and controls were 78.1%, 21.9% and 67.4%, 32.6 % respectively. There was a significant difference in the frequencies of G/G genotype (CI=1.8-7.1, OR=3.47, P=0.00001) and G allele (CI=1.34-2.23, OR=1.72, P=0.0001) between HBV patients and the control group. Conclusions: These findings suggest that the IL6-174 C/G genotype and the G allele are strongly associated with susceptibility to HBV infection. Demographic information showed that most of the subjects were male (74.4%). According to high frequency of G/G genotype in male participants (63.1%) men probably are more susceptible to hepatitis than women.

Objectives : Findings from behavioral genetics which demonstrate the high heritability of personality traits have stimulated the search for the specific genes underlying personality. A large number of association studies have investigated a correlation between serotonin transporter-linked promoter region(5-HTTLPR) polymorphism and personality traits but the results have been inconsistent. So, the aim of this study is to investigate in a large sample with homogenous background about ethnicity, gender, occupation, and age. Methods : The participants included 247 healthy Korean female adults(mean age=23.12, SD=3.22)with no history of psychiatric disorders and other physical illnesses. Genomic DNA was extracted from peripheral blood, and genotyping was performed by PCR. Personality assessment was done with the Temperament and Character Inventory(TCI). Results : Genotype Frequencies are l/l 3.6%, l/s 32.8% and s/s 63.6%(l allele:20%, s allele:80%). This low frequency of the l allele and l/l genotype was different from Caucasian results. No significant association was observed between 5-HTTLPR polymorphism and personality traits in a Korean female population. Conclusions : This study investigated the association between 5-HTTLPR polymorphism and personality traits in Korean female subjects, a large sample with homogeneous background about ethnicity, gender, occupation, and age. No significant association was observed between 5-HTTLPR polymorphism and personality traits in a Korean female population.

Purpose: To explore premature infants' pain response to routine procedures in the neonatal intensive care unit (NICU). Methods: The participants were 56 preterm infants who showed 149 pain responses to 8 high frequency routine procedures which were evaluated using the Premature Infant Pain Scale (PIPS). Videotaped recording was used for data collection. Data were analyzed with descriptive analysis, paired t-test, and Pearson's correlation coefficient. Results: PIPS scores for each procedure were as follows; for removal of central catheter dressing, 6.17 (2.04), venous sampling, 6.12 (2.87), intramuscular injection, 6.05 (2.38), insertion of a peripheral line, 5.38 (2.16), insertion of feeding tube, 4.40 (1.34), heel stick, 4.33 (1.23), insertion of central line, 4.00 (2.12), and endotracheal suctioning, 2.90 (1.25). PIPS score was negatively correlated with gestational age (r=-.218, p=.007) and birth weight (r=-.249, p=.002) among general characteristics of the infants. Conclusion: The majority of 8 routine procedures were found to be painful for premature infants in the NICU. Therefore, adequate pain management related to procedures should be provided to premature infant in the NICU.

Objective : The purpose of this study is to learn the effects of Musimgigong supine position Doyin-therapy (MGSDT) on the autonomous nervous system (ANS) and musculoskeletal system (MSS), and to know how much MGSDT is useful for relaxing the human body. Methods : Eight oriental medical doctors participated in the experiment, who have trained Musimgigong for 6 years or more. Before and after applying MGSDT, we measured BVP/HR, respiration rate, peripheral temperatures, skin conductance, and EMG, using Procomp Infinity and Biograph Infinity of Thought Technology Ltd Results and Conclusions : 1. After the treatment, the participants in MGSDT group reported that they felt refreshed and relaxed. 2 By analyzing the measured data, we observed significant difference in respiration rate(p=.026<.05) and SC(p=.013<.05) before and after applying MGSDT. We also observed relaxing effect in BVP/HR, EMG, but was not significant. On the other hand Temp was stressed but was not significant. Conclusion is that MGSDT can be considered to have an effect on relaxing ANS. Therefore MGSDT could have useful clinical effect to autonomic imbalance.
