  • Spectrum sensing is a key technical challenge for cognitive radio (CR). It is well known that multicycle cyclostationarity (MC) detection is a powerful method for spectrum sensing. However, a conventional MC detector is difficult to implement because of its high computational complexity. This paper considers reducing computational complexity by simplifying the test statistic of a conventional MC detector. On the basis of this simplification process, an improved MC detector is proposed. Compared with the conventional detector, the proposed detector has low-computational complexity and high-accuracy sensing performance. Subsequently, the sensing performance is further investigated for the cases of Rayleigh, Nakagami-m, Rician, and Rayleigh fading and lognormal shadowing channels. Furthermore, square-law combining (SLC) is introduced to improve the detection capability in fading and shadowing environments. The corresponding closed-form expressions of average detection probability are derived for each case by the moment generation function (MGF) and contour integral approaches. Finally, illustrative and analytical results show the efficiency and reliability of the proposed detector and the improvement in sensing performance by SLC in multipath fading and lognormal shadowing environments.

  • Objectives : The purpose of this study was to determine the association between musculoskeletal workload and job stress in early childcare teachers. Methods : This study was based on The Korean Working Condition Survey conducted on wage workers. The total number of individuals included in the analysis was 395 (286 childcare teachers and 109 kindergarten teachers) early childcare teachers in 2011. The collected data were analyzed by frequency statistic, cross-tabulation analysis and logistic regression. Results : The adjusted odds ratio showed a statistically effective association for job stress exposure. The results were as follows: education level, service environment, emotional labor, fatigue or posture led to pain for a high level of job stress. Additionally, for childcare teachers, the results showed that fatigue or posture led to pain when moving a heavy object frequently. Conclusions : When childcare teachers are assigned a task to lift heavy or awkward or objects, care should be taken on who is assigned the task, and it should be done safely. An intervention program should be developed to train childcare teachers to safely and efficiency do heavy labor in early childcare education classes.

  • Objectives: In recent years, pregnancy rate among female adolescents has increased and caused a variety of physical and social problems. Therefore, this study aimed to investigate sexual behavior, delinquent behavior, and pregnancy rate among Korean female adolescents. Methods: In light of the growing interest in adolescent pregnancy, this study conducted a web-based survey, titled "The 2006 Youth Health Risk Behavior Survey." The Korean Center for Disease Control (KCDC) collected questionnaire responses from 34,200 young women. The collected data were analyzed through chi-square test and logistic regression using SPSS Win 14.0 version. Results: This study analyzed main factors, which can predict pregnant experience. The statistic results showed two types of the predicting factors: (1) personal factors: sexual relations after drinking (odds 25.1), Narcotic drug taking (odds 13.0), sexual violence act (odds 7.0), part-time job(odds 2.5), drinking, smoking ; and (2) environmental factors: stepfather(odds 4.2) and natural mother. Conclusion: The influential factor identification for predicting pregnancy rate is important to develop an effective education program for preventing the adolescent pregnancy. The education programs with referring to the identified factors can contribute to reducing the unwilling pregnancy rate of young woman.

  • For this study we conducted a survey far elementary students from 3rd to 6th grade. We performed a frequence test using statistic program and the cross-tabs between gender and grade. We then conducted a thorough interview with the students, after constructing several meaningful questions reflecting the results of survey. As a result of this study, it was critical to arrange interesting inquiry activities in order to foster student's preference for science and attract them to get involved in the science class. We found that teachers were needed to be more flexible to make a group during the classes and teachers would succeed to reflect student's characteristics. In addition, it is necessary for the teachers to refrain from excessive advising or immoderate interrupting student's experiment activity. We conclude that only when the improvements in the curriculum for science education should be made, teachers would allow students to recognize its significances by themselves, and let them follow the inquiring process during the laboratory class for themselves.

  • The study tried to develop a parent-involvement sex education program and find out its effects for more effective sex education methods for high graders of a primary school. The subjects were recruited from 5 classes of 6th graders in Y Primary School in N city, Kyeonggido province, South Korea. Data collection was done from October 4, 2003 to November 7. The experimental group consisted of 43 students from 3 classes with the help from class teachers and parents' involvement in the program. The control group consisted of 43 students randomly sampled by computer from the other two classes. For the experimental methods, the experimental group was given a parent-involvement sex education program as well as a student sex education program: the control group only received the student sex education program. The results were analyzed according to frequency, percentage, $x^2$-test, fisher's exact test and t-test using SAS program. As a result of the homogeneity test, both the groups proved to be the same (t=-0.29 p=0.77, t=0.49 p=0.62) in preliminary sex-attitude and sex-related communication frequency score. But the two group showed meaningful differences (t=2.52 p=0.01, t=2.04, p=0.04) in preliminary sex-knowledge and sex-related communication quality score. After the sex education programs, the two groups didn't show meaningful statistic differences(t=-0.42 p=0.68, t=1.57 p=0.12) in preliminary sex-knowledge and sex-related communication quality score. But the experimental group was statistically more meaningful (t=2.16 p=0.03, t=4.86 p<0.0001) in the difference of sex attitude and sex-related communication frequency than the control. The parent-involvement sex education program developed in this study was more effective for improving their sex attitude and for increasing the frequency of their sex-related communication with parents than the existing student program. Therefore, for sex education, it's necessary to develop and spread various programs where parents can be involved.
