Background: Outcome-expectation beliefs and knowledge may ultimately influence behavior for cancer prevention. The aims of this study were to measure changes in knowledge and beliefs about cancer prevention before and after viewing a television advertisement and identify the factors affecting receptivity to its messages. Materials and Methods: A one-group pretest-posttest design was used in this study of 1,000 individuals aged 20 to 65 years who were recruited online in November 2014. The outcome variables included cancer prevention beliefs based on the Health Belief Model (five items) and knowledge about risk factors for cancer (seven items). Results: Perceived susceptibility, perceived benefits, and self-efficacy increased significantly and their perceived severity and perceived barriers decreased significantly, after participants viewed the television advertisement. Correct responses to questions about risk factors also increased significantly, except for smoking. The main factors affecting changes in the outcome variables were age, interest in cancer prevention, social network, satisfaction with the ad, and pretest scores. Conclusions: Television advertisements with positive frameworks can be an efficient channel of improving beliefs and knowledge about cancer prevention in a short period. The continuous development of intervention materials that consider the demographics, needs, and satisfaction of the target group will be necessary for future studies.

In this paper, we describe the composition of frequency response bands based on experimental data of plants (controlled systems) with uncertainty and nonlinearity, and the robust stability evaluation of feedback control systems. Analysis and design of control systems using the upper and lower bounds of such experimental data would be effective as a practicable method which is not heavily dependent upon mathematical models such as the transfer function. First, we present a method to composite gain characteristic bands of frequency response of cascade connected plants with uncertainty and a recurrent inequality for the composition. Next, evaluation methods of the robust stability of multi-loop control systems obtained through feedback from the output terminals and multi-loop control systems obtained through feedback into the input terminals are described. In actual control systems, experimental data of frequency responses often depends on the amplitude of input. Therefore, we present the evaluation method of the nominal value and the width of the frequency response band in such a case, and finally give numerical examples based on virtual experimental data.

This study was done to examine the sexual knowledge, attitudes, and behaviors of Korea college students and investigate the effects of sexual education programs on college students with respect to their sexual knowledge and sexual attitudes. For these objectives, a single 92 item sexual questionnaire was administered to 213 college students (113 in the experimental group and 100 in the control group) as a pretest one day before the experimental group participated in a sexual education program. Then a three week sexual education program was given to the experimental group and a posttest was administered to both groups day after the program. The findings from the pretest； 1) The main sources of sexual information were friends, Internet, books and magazines. College students in this study showed relatively high scores on their overall sexual knowledge but showed low scores on their knowledge of venereal disease and HIV/AIDS. Female students had a higher sexual knowledge of physiology, pregnancy and sexual abuse than male students. 2) The overall sexual attitudes of college students were subjective. They showed especially strong liberal attitudes to premarital intercourse, had few double standards and agreed on induced abortion. Male students showed a more liberal attitude to premarital intercourse and extramarital intercourse (X²＝50.679, p＜.001). Christian students showed the lowest rates of permissiveness for induced abortion than students of other religions. 3) 64.9％ of the subjects in this study had experience in intercourse. The gender and age of students did influence the experience rates of intercourse. Male students had much higher rates of intercourse than female students (X²＝13.565, p＜.001) and older students had higher experience rates of intercourse. 4) From the analysis of the relationship between sexual knowledge, attitudes and behaviors, this study revealed that sexual knowledge and sexual attitudes of college students have a correlation 6＝0.324, p＝0.000). Students' experience of intercourse did not influence their sexual knowledge scores, but did influence their sexual attitudes. Students who had experience of intercourse showed more liberal sexual attitudes than those students who did not (t＝2.677, p＜.050). And students who were exposed to sexual media such as pornography, sexual magazines, sexual books and the Internet, also showed more liberal sexual attitudes than those students who were not. The findings from the comparison of pretest and posttest ； 1. The sexual knowledge of the experimental group that participated in the sexual education program was significantly increased after the program compared to before the program (p＜.001). However the control group did not show any significant change in their sexual knowledge. 2. The sexual attitudes of the experimental group were also changed significantly becoming less liberal (p＜.001). The control group also showed significant change in their sexual attitudes, also becoming less liberal (p＜.001). Therefore, the sexual education program used in this study was effective in increasing college students' accurate sexual knowledge, but had little effect on their sexual attitudes.

The purpose of this study is to examine the effect of the sex education program on the elementary school students' sex-related knowledge and attitude. The research method used in this study is an equivalent control group pre-test and post-test and post-test design in a quasi-experimental research format. The subjects of this study were the 5th-grade elementary school students(63 in the experimental group and 60 in the control group) in O and O elementary school in G city. The data was collected from April 4th to July 3th, 2003. The experimental group received a sex education program while the control group did not receive any treatment. The sex education program was implemented for 40 minutes every 2-3 days which total twelve sessions over 4 weeks. Using the SPSS 10.0 program, the data was analyzed by $X^2$ - test, Fisher exact test, t-test, and a repeated measures ANOVA., Rrsults : The experimental group who received the sex education program showed a significantly higher sex-related knowledge score than the control group (F=140.52, p=.001). The experimental group showed a significantly higher sex relatied attitudes score than the control group (F=40.80, p=.001). This study concluded that the sex education program was effective in both sex-related knowledge and attitudes for elementary school students. Therefore, it appears to be effective for 5th-grade students to receive intensive sex education. It es recommended that the schools and government develop education media and a sex education program for parents, have a sex education teacher and a place where students can be counseled, and a professional consultant who can effectively counsel the students regarding sex-related issues.

This study investigated the correlations of the AIDS knowledge, self-esteem, sense of control, optimistic bias toward AIDS, and condom use in the Chinese male college students. A cross-sectional survey was used, and 307 male students were recruited from anonymous universities in cities of two provinces in China. The data were analyzed according to descriptive statistics, ANOVA, Pearson's correlations. The Chinese male college students had an optimistic bias toward AIDS. The score of AIDS knowledge was 73%, and the self-esteem and sense of control scores were all rated higher than the median. The difference among groups according to grade and age were statistically significant in this study. The self-esteem, sense of control, and optimistic bias toward AIDS showed significant positive correlations, but AIDS knowledge, optimistic bias, and condom use have no correlations. The studies that examine psychological variables with condom use among various groups should be followed in the Chinese context.

Purpose: The purpose of this study was to investigate the effects of a structured preoperative PCA education on the knowledge and attitude regarding PCA usage, level of pain, and the consumption of analgesics after operation for colorectal surgery patients. Methods: This study was conducted from 18 Feb to 2 May, 2008. Participants were 80 colorectal cancer patients who would use the IV-PCA after colorectal surgery in a cancer hospital in Gyeonggi-do, Korea. Two groups, experimental and control were consisted of 40 patients each. The 20-minute structured education regarding PCA usage was applied to each patient individually in the experimental group but only the routine anesthetic consultation was given to each patient in the control group the day before the surgery. The SPSS/PC 10.0 program was introduced to analyze the collected data on frequency, percentage, mean, standard deviation, $x^2$-test, t-test and paired t-test. Results: The experimental group with the structured preoperative PCA education showed higher knowledge and more positive attitudes regarding the PCA usage than the control group. Also the experimental group showed better pain control and lower consumption of analgesics at 4, 8 and 24 hours after than the control group. Conclusion: The structured preoperative PCA education is an effective nursing intervention for improving the knowledge and attitude of the colorectal surgery patients on the PCA usage, and enabling the patient to take the analgesic more effectively with lower consumption, while reducing the patients' pain after operation.
