선그래프는 과학에서 정보를 전달하는 수단으로써 뿐만 아니라 실험의 결과를 해석하는 수단으로 유용하게 활용된다. 그러나 학생들은 그래프의 시각적이면서도 추상적인 특징 때문에 해석이나 이해에 상당한 어려움이 있다. 따라서 선그래프 이해의 지각ㆍ인지 과정을 분석하는 것이 매우 중요하다. 본 연구의 목적은 선그래프 해석과 이해에 관한 지각ㆍ인지 과정에서의 한 모형을 제시하는 것이다. 이 모형은 Pinker의 그래프 도식 이론과 Fisher의 정보 처리 이론에 기초를 두고 있으며, Lohse, Shah, Winn 등의 연구를 참고하여 제시하였다. 그리고 이 모형의 특징은 선그래프 문제를 해결하는 과정을 내용 독립적인 선그래프 해석과정과 내용 의존적인 선그래프 이해과정으로 나누었다. Line graphs are particularly effective in communicating relationships. They can convey vast amounts of information that cannot be communicated effectively by words or numbers alone. Thus, line graphs allow us to communicate scientific information and to see scientific data analyses. However, students are weak in their ability to comprehend line graphs because the features of line graphs are visual and abstract. McDermott et al. (1983) have shown that this is a problem even for many university students in the sciences. Then, it is very important to analyze the perceptual and cognitive processes in the comprehension of line graphs. The purpose of this study is to propose a model of line graph comprehension that includes perceptual and cognitive processes. This model is based on the graph schema theory of Pinker (1990) and the information processing theory of Fisher (1992). The major processes are the interpretation process and the comprehension process. In the interpretation process of line graphs, defined that the visual information of graphs is assimilated with the graph schema and is simultaneously accommodated to graph schema. The comprehension process of line graphs is one in which the result of the graph interpretation is assimilated with the existing conceptual schema on graphs and is simultaneously accommodated to the existing conceptual schema on graphs.

This study aims to reanalyze the meaning structure of and find the theme of this story. Till now, there have been several studies about this story. But most of the studies ignored the importance the dream world that includes the central meaning of this story. And the studies cannot enough to explain the overall feature of this story. The best method to find theme is to understand the narrative structure of story. The narrative structure of the story is mostly influenced by traditional narrative genre. Therefore we have to confirm from which genre is borrowed. Next, we have to inspect closely the specific narrative structure of this story, and research what characters of this story play role. The theme of this story is follows; the hero is in trouble because he cannot know the mothed of real life. The theme of this story has the indissoluble connection with the author. The author resigned from public life and lived in retirement. We believe, this situation of the author has a close connection with the narrative structure of this story.

In recent years, depression is most commonly reported psychiatric condition after stroke, poststroke depression(PSD) has attracted world-wide interest. This review focuses on the major research themes that have emerged. Pooled data from studies, have wide variation in results is due to different criteria for patient selection, different evaluation methods, diagnostic criteria and poststroke intervals, conducted throughout the world have found prevalence rates for from 18% to 65%. The diagnosis of PSD is most appropriately based on a structured mental state exam and DSM-N criteria for depression due to stroke with major depressive-like episode or depressive features. Rarely, poststroke patients may also develop bipolar mood disorder. The treatment of PSD, single antidepressant showing efficacy and electroconvulsive theraphy(ECT) and behavioral therapies have also effective. The progression of recovery following stroke can be altered by treating depression, which has been shown to improve recovery in activities of daily living(ADL) and cognitive impairment and to decreased mortality. The mechanisms underlying the association of stroke and mood disorder are important areas for future investigation.

Since the emergence of the term premenstrual syndrome (PMS) in the 1950s, PMS has become an increasingly discussed topic in popular media sources. Thus self management techniques are easily accessed by women through the media or through their peers. Premenstrual dysphoric disorder (PMDD) comprises extremely distressing emotional and behavioral symptoms. Women with PMDD report premenstrual symptoms, primarily mood symptoms, that are severe enough to seriously interfere with their life style and relationships and usually do not respond to conservative and conventional interventions. Although women with PMS are most often seen in primary care or by their obstetricians/gynecologists, the result of recent study suggested a high rate of missed diagnoses. The premenstrual syndromes include the more common PMS, the less prevalent PMDD, and menstrual psychosis. The etiology of PMS and PMDD is still largely unknown. That PMS and PMDD are primarily biological phenomena is underscored by recent, convincing evidence. Therapeutic interventions for PMS and PMDD range from the conservative to treatment with psychotropic medication and, for the more extreme cases, hormonal therapy or surgical procedures.

This study was conducted to examine aspects of health and safety education and demand level of safety education in construction job sites in order to provide direction of safety education development. The subjects of this study were 566 workers who were working in construction job sites located in Daegu City and Kyungbuk Province. Data were collected from June 1, 2002 to August 30, 2002. The results of this study can be summarized as follows. 1. According to safety education by experience methods, the proportion of education by lecture was highest (90.6%). The proportion of education by field practice was 13.1%. 2. Among the education methods which they thought as the most desirable method, the proportion of audio-visual education was 39.4% and the proportion of education by experience was 37.5%. Those who had more monthly income and higher education level preferred audio-visual education, while those who were younger and less educated preferred education by experience. 3. In the case of the contents of the safety education which they thought as the most important one, the proportion of enhancement of safety awareness and education of risk factors was highest (24.7%). The groups of older workers, having longer working period, and belonging to higher education level preferred these contents. 4. According to the factors which were most important to increase effectiveness of the safety education were workers' voluntary participation (27.7%), 40 to 49 years old (27.7%), and monthly income of one million, five hundred thousand won to one million, nine hundred ninety thousand won (32.0%). The proportions of lower educated workers and working as daily workers were also high. 5. The variable which most influenced the safety education was age. The safety awareness of construction job sites was the second highest influential variable. From above results, it is clear that the workers' participation in the safety education was low since most of the safety educations were formal education by lecture. Although they participated in the education, the education was also not effective because they compulsorily participated in it. Therefore, it can be concluded that effective alternative policies must be formulated.

This study intended to examine the changes of residential building characteristics in period classification. The results of this study are as follows: During Joseon dynasty, it is judged that the social changes in the ideology of ruling classes did not directly affect the traditional residential style. The mid period and latter period of Joseon, it is changed toward horizontal and practical residential layout in place of confucian courtesy based style. During port opening period, the traditional residential style was remodeled through addition of glass panes to inter-chamber floor in tune with the influx of modern materials and ideologies like glass or cement etc. The Japanese ruling era of Korea period, the modern housing style of room separation type was settled.

Finite strip method, developed by Cheung to improve the finite element method, uses trigonometric series as longitudinal interpolation functions. Although this method is useful and highly accurate for simple structures, it cannot be used for structures with complex boundary conditions. The objective of this study is to get rid of this effect of finite strip method using B-spline functions as displacement functions in analyzing plates. Stiffness matrices are derived using principle of minimum total potential energy for a plate element. An algorithm is developed and applied to plate with various boundary conditions. To demonstrate the accuracy and versatility of developed method, the results of the method were compared with those from the closed-from solution and the finite element method. As a result, the presented method is proved to be more accurate and economical than the finite element method, and applicable to plates with complex boundary conditions.

Study on the synthesis of chemical nucleases that have ability of cleavage of RNA or DNA to investigate the structure of nucleic acids was performed. We synthesized Ni-complex that was synthesized by Karn and Busch (1966) and identified the specificity and ability as chemical nuclease by Chen. et. al. (1993), and Cu-complex and Cd-complex that were presumed as having specificity similar to Ni-complex in terms of the structure and specificity and ability as chemical nuclease. The spectra of synthesized new transition metal complexes were compared with those of Ni-complex. Results of comparing data of UV and IR spectra of Cu-complex and Cd-complex with those of Ni-complex showed that the structures of newly synthesized transition metal complexes were similar to the structure of Ni-complex. The yield of synthesis of Ni-complex, Cu-complex, and Cd-complex was 81%, 7%, and 39% respectively.
