This study aimed to investigate primary students' science-related attitudes through the literature review. Ninety-four papers published in domestic science education journals, since 1990, were collected and were followed by content analysis. In this study, science-related attitude was conceptualized as attitude toward science, scientist, science-related occupations, and school science, which is composed of cognitive, affective and behavioral domains. Based on the conceptualization, the instruments used for measuring students' attitudes were analyzed. The analysis of definition of science-related attitude in the articles showed different foci on cognitive, affective and behavioral domains. To suggest the effective instruction for enhancing students' science-related attitudes, this study identified students' attitude with gender, grade, residence and achievement level. The result showed that male, urban, higher-grade and better performed students had more positive attitude than female, rural, lower-grade and less performed students. As for the factors in science-related attitude, I categorized the factors into personal, environmental and pedagogical aspects, and found that psychological elements in all domains were most influential to students' change of science-related attitudes. It is interesting to note that students showed dichotomous views about experiment and that task-oriented instruction failed to enhance students' attitude. Based on the research findings, this study suggests effective instruction for improving students' attitudes and future research for science education.

The status of Pinworm (Enterobius vermicularis) egg positive rate of Primary school children in Geoje island was investigated by using adhesive cellotape anal swap method, in September, 2002. Total egg positive rates of E. vermicularis were 9.8% (74/754) and those of male and female were 10.8% and 8.7%, respectively. Among three schools examined, Myeongsa primary school showed the highest egg positive rate (12.6%) followed by Yeoncho [9.8% (26/266)] and Geoje［9.1% (35/385)]. As for the age groups, the 2nd grade had the highest egg positive rate (15.3%), whereas the 5th grade showed the lowest egg positive rate (2.6%). The above result led us to confirm that the egg positive rates of E. vermicularis in primary school children in Geoje island were not significantly different from the those in the whole country including urban and rural areas, showing more than 10%.

Purpose: To assess the effect and safety of lobaplatin combinated floxuridine /pirarubicin in transcatheter hepatic arterial chemoembolization(TACE) of unresectable primary liver cancer. Patients and Methods: TACE combined with the chemotherapy regimen was used to treat 34 unresectable primary liver cancer patients. DSA/MRI/CT/blood routine examinations were used to evaluate short term activity and toxicity after 4-5 weeks, the process being repeated if necessary. Results: Among the 34 cases, 1 (2.9%) showed a complete response, 21 (61.7%) a partial response, 8 (23.5%) stable disease, and 4 progressive disease, with a total effective rate of 67.6%. The content of alpha fetoprotein dropped by over 50% in 20 cases (58.8%). The rate of recovery was hepatalgia (88.2%), ascites (47.1%), appetite (55.9%), Performance Status(30.4%). The median follow-up time (MFT) was 281 days (63-558 days), and median progression-free survival was 118.5 days (95%, CI:88.8-148.2days). Adverse reactions (III-IV grade) were not common, with only 4 cases of vomiting and 2 cases of thrombocytopenia (III grade). Conclusions: Lobaplatin-based TACE is an effective and safe treatment for primary liver cancer.

Background: Primary pulmonary malignant mesenchymal tumors are rare, constituting only 0.4% of all lung cancers. Since sarcomas are chemo/radio-resistant, surgical resection is the optimal treatment choice for patients with suitable medical conditions and tumor stage. In the present study, we analyzed the surgical outcomes and survival of primary pulmonary malignant mesenchymal tumors treated surgically. Methods: We retrospectively examined the records of patients with primary pulmonary malignant mesenchymal tumors who underwent surgical resection at our department between January 2010 and December 2020. Patient data were analyzed according to age, sex, tumor grade and stage, resection completeness, surgical type, and tumor histopathology. Results: Twenty patients were included in the study. There were 13 men (65%) and 7 women (35%). The median survival rate was 36 months (range, 19-53 months), and the 5-year overall survival rate was 37%. Unfavorable prognostic factors for overall survival included parietal pleural invasion (p=0.02), high tumor grade (p=0.02), advanced tumor stage (p=0.02), and extensive parenchymal resection (pneumonectomy and bilobectomy, p=0.01). The median length of disease-free survival was 31 months (interquartile range, 21-41 months), and the 5-year disease-free survival rate was 32%. The most unfavorable prognostic factors for recurrence were parietal pleural invasion (p=0.02), high tumor grade (p=0.01), and tumors requiring lung resection with chest wall resection (p=0.02). Conclusion: Primary malignant mesenchymal lung tumors are aggressive and have a high mortality rate. However, acceptable overall and disease-free survival rates can be obtained with surgical therapy.

Primary students' conceptions on the atmospheric pressure and its related concepts were investigated. Samples consisted of 41 5th grade and 43 6th grade primary school students. Two types of research methods were used: 1) the open-ended written questionnare;2) paper-pencil test. Naive theories on the atmospheric pressure and its related concepts were numerous. For example, 80% students thought that as we go higher into the atmosphere, the atmospheric pressure becomes greater. Also, 50% students thought that the hot air had greater the atmospheric pressure than the cold air. This study was also discussed the teaching strategies to overcome these naive theories on the atmospheric pressure and its related concepts.

Purpose: The purpose of this study was to identify the lipid profile ratios as factors affecting disease progress in patients with high-grade primary brain cancers undergoing concurrent chemoradiotherapy (CCRT) and adjuvant chemotherapy. Methods: The levels of lipid profile ratios were evaluated by looking at the total cholesterol (TC) to high-density lipoprotein (HDL)-cholesterol (TC/HDL-c), low-density lipoprotein (LDL)-cholesterol to HDL-cholesterol (LDL-c/HDL-c), and triglycerides to HDL-cholesterol (TG/HDL-c). This descriptive research was conducted 7 months after the initiation of CCRT and adjuvant chemotherapy. Results: A total of 36 patients with newly diagnosed primary malignant brain cancer were included in the study. The levels of lipid profile ratios such as TC/HDL-c, LDL-c/HDL-c, TG/HDL-c were significantly different between the patients with and without disease progress at 7 months after initiation of CCRT and adjuvant chemotherapy. Conclusion: The lipid profile ratios were indicators affecting disease prognosis with tumor-related factors at 7 months after initiation of CCRT and adjuvant chemotherapy. Therefore, lipid profile ratios indicating hyperlipidemia in patients with high-grade brain cancers should be carefully monitored during and after cancer-related therapy.
