The purpose of this study was to explore strategies used by pre-service elementary science teachers in planning a science lesson. The participants were six senior students from a national university of education located in the midwestern area of Korea. Data regarding their planning strategies were gathered through both thinking-aloud and observation. Research findings suggest that: three of the teachers had little understanding of the necessity of reviewing unit contents or prior learning for planning a science lesson; five student teachers relied heavily on learning objectives presented in teachers' guidebooks without considering their appropriateness; all teachers exhibited an intention of composing different activities or teaching approaches from teachers' guidebooks; only two teachers thought about learners' prior knowledge or understanding levels; five and three teachers had poor understanding of discovery learning models and importance of teacher's questioning, respectively; and five teachers paid little attention to assessment.

The purpose of this study is clarify consumer problem on the basis of understanding consumer behavior, that is, to make explicit the effect of economic levels and educational background upon consumer consciousness and consumption behavior. The data in this study is from a survey in 1973 by means of a questionnaire of the opinions of 200 housewives of Seoul. The ${\chi}^2$(Chi-Squire) was applied for the statistical analysis of the data and following results were found. Generally consumers lack understanding of economic matters and satisfactory consciousness on matters of consumption life. And there is significant difference among the class on several matters. That is, the lower economic level and educational background are, the lower the understanding of economic matters and consciousness of satisfaction are. So the consumer education must be carried out for lower class of economic level and educational background. And in the present awakening of salers and makers is needed for consumers.

Currently, inappropriate information regarding cancer is being disseminated indiscreetly via the media and Internet. Many people are confused due to the mixed presence of facts and misinformation concerning cancer. Owing to the flood of information, especially that concerning gastrointestinal cancer (the most common cancer in Korea), patients with gastrointestinal cancers, their family members, and medical staff, as well as the general public, are faced with a number of problems in understanding, treating, and overcoming this type of cancer. Therefore, investigating the level of recognition for and understanding of gastrointestinal cancers among these populations is very important for the prevention, diagnosis, and management of this disease. This review article investigated the differences in the recognition levels of the general understanding, prevention, quality of life, pain control, and the ethical issues of gastrointestinal cancer treatment among the general public, patients with gastrointestinal cancers, their family members, and medical staff via surveys.

Sleep is essential to brain function and mental health. Insomnia and obstructive sleep apnea (OSA) are the two most common sleep disorders, and are major public health concerns. Proton magnetic resonance spectroscopy (¹H-MRS) is a non-invasive method of quantifying neurometabolite concentrations. Therefore, ¹H-MRS studies on individuals with sleep disorders may enhance our understanding of the pathophysiology of these disorders. In this article, we reviewed ¹H-MRS studies in insomnia and OSA that reported changes in neurometabolite concentrations. Previous studies have consistently reported insomnia-related reductions in γ-aminobutyric acid (GABA) levels in the frontal and occipital regions, which suggest that changes in GABA are important to the etiology of insomnia. These results may support the hyperarousal theory that insomnia is associated with increased cognitive and physiological arousal. In addition, the severity of insomnia was associated with low glutamate and glutamine levels. Previous studies of OSA have consistently reported reduced N-acetylaspartate (NAA) levels in the frontal, parieto-occipital, and temporal regions. In addition, OSA was associated with increased myo-inositol levels. These results may provide evidence that intermittent hypoxia induced by OSA may result in neuronal damage in the brain, which can be related to neurocognitive dysfunction in patients with OSA. The current review summarizes findings related to neurochemical changes in insomnia and OSA. Future well-designed studies using ¹H-MRS have the potential to enhance our understanding of the pathophysiology of sleep disorders including insomnia and OSA.

Purpose: The purpose of this study was to identify the relation between personality traits and awareness of gender equality. Method: A descriptive survey design was used and 688 students in fifth and sixth grades in 3 elementary schools were selected as participants. Result: 1. Level of gender equality awareness among the students was 2.82. This is higher than average and was most influenced by awareness of family life, followed by awareness in education, work environment and social-cultural life. 2. Students with higher levels of extraversion-introversion had higher levels of awareness of gender equality in family life, work environment, and education. Students with higher levels of tough-mindedness showed lower levels of gender equality awareness in family life and work environment, while those with higher levels of lying showed lower levels of gender equality awareness in social-cultural life. Conclusion: Personality traits and awareness of gender equality were correlated to some degree. However, in order to understand the characteristics of childhood personality traits and the behaviors of our children though the mediation of the gender equality awareness as society changes, and to let them grow with understanding of gender equality, it is essential to implement various kinds of education in families, schools, and the society.

Purpose: The purpose of this study was to identify the levels of body image, sexual intimacy, and sexual satisfaction, and to explore factors affecting sexual intimacy and satisfaction among women within one year of mastectomy. Methods: The present study was a cross-sectional survey and involved 101 women who had undergone mastectomy at a University hospital of D city, Korea. Measurement included the scales of body image, sexual intimacy, and sexual satisfaction. Results: Mean age of the subjects was 51 years. Scores of the body image, sexual intimacy, and sexual satisfaction were 59.62, 90.69, and 69.04, respectively. Body image, sexual intimacy, and sexual satisfaction were significantly related to each other. Sexual intimacy was higher when women were of young age (${\beta}=-.32$), had a shorter period since surgery (${\beta}=-.24$), and with higher levels of body image (${\beta}=.37$). Sexual satisfaction was higher when women had higher levels of body image (${\beta}=.19$) and greater levels of sexual intimacy (${\beta}=.74$). Conclusion: Higher levels of body image and greater levels of sexual intimacy were identified as the significant factors influencing sexual satisfaction among these women. Future research with a mixed-method research is needed to gain a deep understanding of the sexuality between women and their husbands.

본 연구는 삼각함수와 관련된 과제를 통해 고등학교 학생들의 함수 개념 이해 정도를 Hitt(1998)의 층위 분석을 통해 살펴보았다. 우선 학생들의 함수 이해 정도를 층위 분석을 통해 단계를 구분한 후 이해 관점을 과정과 대상 관점으로 다시 분류하였다. 그 결과 고등학교 학생들의 함수 개념 이해의 정도 층위는 3단계에서 불완전성을 보였다. 그리고 함수의 이해의 관점은 그래프 해석에서 과정 관점이 주를 이루고 있으며 대수적 표상의 조작이 중요시되고 있음을 알 수 있었다. 이러한 결과를 바탕으로 삼각함수를 다양한 관점으로 이해할 수 있는 교수-학습 방법에 대한 연구와 함께 문제 해결과 그에 따른 표상 체계 사이의 일관성이 유지되는 함수 개념 이해 층위 5단계에 도달할 수 있는 수업모델의 연구가 필요할 것으로 보인다.
