Recently, the use of an electrical apparatus has brought up concerns of health risks from exposure to electromagnetic fields. EMF is composed of electric fields and magnetic fields. Heavy exposure to EMF can occur only in the vicinity of high-voltage overhead transmission lines, close to transformers and underground cables, and also close to large electrical machinery. In this thesis I have investigated the hypothesis of the correlation between occupational exposure to ELF-EMF and the risks of leukemia, anemia, cancer. Therefore, the aim of this study is to investigate whether or not ELF-EMF emitted from electric power stations and transformer substations affect some hematological parameters and tumor markers of electric utility workers. The hematological test results and tumor markers under investigation were similar in the two groups but some of parameters such as RBC, AFP, LDH showed significant difference between the two groups from two sample t-test (p<0.05). The exposure group showed increased LDH level compared to the control group by two sample t-tests. In addition, the abnormal LDH level in the exposure group was observed to be clinically significant by ${\chi}^2$-test. However, the levels of RBC, AFP observed were not clinically significant by ${\chi}^2$-test (p>0.05). These results suggested that ELF-EMF does not affect most blood test parameters except LDH of electric utility workers.

The purpose of this study was to obtain basic data for the prevention and control of adolescent back pain through analyzing connections between study environments and physical posture. The subjects were 960 male general high school students in the Chonju area and the data were collected by a self-reported questionnaire from Mar. 17 to Mar. 22, 1999. The collected data were analyzed by a frequency, chi-square and t-test using an SPSS program. The results are as follows; 1) The experience rate of back pain perceived by subjects was 67.5% and by each grade: 1st-27.5%, 2nd-35.4%, 3rd-37.1%. The relationship between grades and the experience of back pain didn't show any significant difference. 2) The causes of back pain perceived by subjects such as 'postures are not good' was 56.7%, 'sitting too much time in a chair' was 39.1%, and 'too severe exercise' was 32.4%. 27.8% had back pain first during the 3rd grade of middle school, and 23.9% had it first during the 1st grade of high school. 3) Intensity of subjects' back pain spread from 'moderate' at 49.6%, to 'severe' at 16.4%. Concerning the frequency of back pain, 58.6% said it was 'irregalar'. 4) Among interventions to deal with back pain: 'move by exercising my back or ask friends to beat my back' was 41.0%, 'just bear it' was 23.1%, and at home 'don't have 'any treatment' was ranked first, at 54.9%. 5) The relationship between subjects' general characteristics and back pain experiences: height (t=-1.99, P=.046), sitting/height (t=-2.61, P=.009), self-perceived condition of health (${\chi}^2=23.530$, P=.000), family history (${\chi}^2=43.903$, P=.000) showed significant difference, but the kinds of transportation, sleeping postures, sleeping method and smoking didn't show significant differences. 6) The relationship between subjects' learning environment and back pain experiences, the height of students' desk and chair showed significant difference (${\chi}^2=23.054$, P=.000), but the sitting time didn't show significant difference. 7) The relationship between the characteristics of subjects' physical postures and back pain experiences: standing postures (${\chi}^2=15.105$, P=.001), and sitting postures (${\chi}^2=20.264$X2, P=.001) showed significant difference, but lifting postures didn't show significant difference.

Purpose: This study was conducted to examine the level of physical activities at time points of pre-illness and current treatment, and the differences in body mass index (BMI), anxiety, depression and fatigue according to their physical activity in cancer patients undergoing chemotherapy. Methods: The survey was used with 126 cancer patients undergoing daily chemotherapy at injection room, cancer clinic of C University Hospital in G city. Data were collected from June to September, 2009 using a structured questionnaire. The data were analyzed by descriptive statistics, chi-square, Fisher's exact test and t-test using SPSS/WIN15.0. Results: The significant increase in physical activity was reported from pre-illness to the time in treatment (${\chi}^2$=69.027, p<.001). The anxiety level of the group with increased physical activity was significantly lower than those who did not (t=-2.218, p =.028). There were no significant differences in BMI, depression, and fatigue according to physical activity. Conclusion: The level of physical activity was significantly associated with the anxiety level of the cancer patients undergoing chemotherapy. Cancer patients should been encouraged regular physical activity during chemotherapy treatment. And an appropriative nursing intervention should be established in order to motivate cancer patients to increase physical activity.

Studies related to Electronic Word-of-Mouth (eWOM) show that the acceptance of eWOM information is an important factor in customer purchase decisions. When consumers accept eWOM information, they tend to use that information in considering before making purchase decisions. In Viet Nam, there are few studies about eWOM information, especially on the acceptance of eWOM information. Research is conducted to test the influence of consumers on the perception of the senders' identity to the acceptance of online reviews (a kind of eWOM) in Viet Nam - a case study in Ho Chi Minh City. Using adjustment techniques, inspecting the scales and a theoretical model represent the relationship among the influential factors. The research is based on a sample of 522 consumers who use the Internet to search for product reviews before buying and used Structural Equation Modeling (SEM) to test the relationships among the variables. The research results show that the scales of the variables: Message Quality, Source Credibility, Perceived Message Usefulness, Perceived Senders' Identity, Perceived Message Credibility, Message Acceptance attain the validity and reliability in the research. The research contributes to the understanding of the determinants that influence the acceptance of eWOM information, which are informational factors, and factors related to consumer skepticism.

초창기 심층 암호의 대부분은 원본 영상의 최하위비트를 비밀 메시지 비트로 치환하는 방식이었기 때문에 인간의 감각으로는 메시지 삽입 여부를 구별해낼 수 없었지만 통계적 분석에 의하여 원본과 은닉물의 구별은 물론, 비밀 메시지의 삽입 량까지도 거의 추정해낼 수 있을 만큼 취약점을 내포하고 있었다. 우리는 Westfeld 와 Fridrich가 판단의 기준으로 정한 통계량을 각각 분석하였고, 이에 근거하여 원본의 통계량을 유지하면서도 대용량의 메시지를 삽입할 수 있는 방법을 제안하고자 한다. 제안하는 방식은 단순히 원본 영상의 최하위 비트를 변화시켜 메시지를 삽입하는 방식이 아닌 원본의 실제 화소 값이 랜덤 하게 증가하거나 감소하는 방식으로 메시지를 삽입하게 된다.

Purpose: This study was to examine the relationship between mental health status and suicidal thinking among cancer patients. Methods: The data set of the 4th Korea National Health and Nutrition Survey (2009) was used and 230 subjects with cancers were included in the present study. Using SPSS/WIN 18.0 program, data were analyzed with descriptive statistics, ${\chi}^2$ test and logistic regression analysis. Results: About one-third of subjects had stress, symptoms of depression and suicidal thinking. Female had more suicidal thinking than male (${\chi}^2$=5.44, p=.020). In addition, subjects with high income level had more thinking about suicide compared with those in low income level (${\chi}^2$=7.54, p=.023). There was a significant difference in suicidal thinking according to the educational levels (${\chi}^2$=13.25, p=.004). In the logistic regression analysis, it was indicated that gender, depression and stress were significant predictors on suicidal thinking, accounting for 26.7~38.1%. Conclusion: From the findings in this study, it was suggested that the healthcare providers should try to improve their mental health status in order to prevent suicidal thinking among the individuals diagnosed with cancer.

본 연구의 목적은 죽음교육 프로그램이 성인의 자아 존중감, 영적 안녕, 통증에 미치는 효과를 검증하는 데에 있다. 연구의 설계는 비 동등 대조군 실험 연구이며, 충청북도 청주시의 C병원에서 2016년 01월 04일부터 13일까지 시행하였다. 본 연구는 참가에 동의한 48명을 대상으로 하였고, 실험군과 대조군에 각각 22, 26 명의 참가자를 무작위로 나누어 배정하였다. 실험군의 참가자들(n=22)은 매 회 2 시간, 주 3회, 2 주간에 걸쳐 죽음교육을 받았다. 실험 처치 효과는 2 주간의 중재 전, 후에 자아 존중감, 영적 안녕, 통증에 대한 구조화된 설문지를 통하여 측정하였다. 자료들은 t-test, chi-square test, Fisher Exact-test and paired t-test를 사용하여 분석하였다. 2 주간의 중재 후 대조군에 비해 실험군은 자아 존중감 (P<.002), 영적 안녕 (P<.015)이 유의하게 증가하였고, 통증 (P<.014)은 유의하게 감소하였다. 죽음교육 프로그램은 성인에게 효과적인 간호 중재로 보인다. 그러므로, 죽음교육 프로그램을 현장에서 적용할 수 있는 가능성을 고려해 볼 수 있겠다.
