The purpose of this study is to analyze the trend line through scatter diagram analysis on correlation between SNS addiction tendencies and learning attitudes, figure out the knee point influencing learning attitudes negatively in detail, and examine influence among subareas. To address the goal, study questions are formulated as follows. First, this author did screening on the data of variables measured and analyzed descriptive statistics. Second, this researcher produced the trend line by drawing a scatter diagram in order to analyze correlation between SNS addiction tendencies, withdrawal symptoms, excessive communication, and excessive time wasting, and learning attitudes exploratorily. Third, to explore correlation between self-evaluation, learning participation, and developmental attitudes, the subfactors of learning attitudes related to SNS addiction tendencies, this author drew a scatter diagram and analyzed the threshold of positive and negative correlation. To verify the study questions, the SNS addiction tendency scale and learning attitude scale were applied to 301 university students in Chungcheong area. According to the study results, first, their learning attitudes are influenced by SNS addiction tendencies, excessive communication and excessive time wasting, and they are not influenced by withdrawal symptoms that much. Second, excessive communication, a factor of SNS addiction tendencies, and self-evaluation and developmental attitudes, factors of learning attitudes, show positive correlation to some extent and indicate negative correlation after the threshold. However, excessive communication and learning participation are found to show no correlation. Third, according to the results of examining correlation with learning attitudes by dividing them into excessive communication and excessive time wasting groups with the knee point of 1.40, as the symptom of excessive communication is found more, it influences self-evaluation, learning participation, developmental attitudes, and learning attitudes more negatively in general. The result of this study is expected to provide foundational material necessary to develop educational programs to prevent undergraduates' excessive SNS use and SNS addiction which can be used in the scenes of counseling or education.

Since. its first description by Albrecht in 1904 that hamartoma (Greek. meaning "error" and "tumor")is tumor-like malformation characterized by abnormal mixture of normal constituent in any organ it arises, hamartoma involving the lung has assumed the following clinical features.: 1) all the pulmonary lesions presenting as "coin lesions", it occupies about 8% according to various reports. It also constitutes the most prevalent lesion of all the benign lung tumors, appearing in 0.25% of the general population. 2) Peak incidence of the lesion occurs in the 5th and 6th decade as the carcinoma patient do, and the occasional growing tendency and periperal location as in this presentation renders the differential diagnosis from the malignant disease difficult and surgical intervention inevitable for definite histological diagnosis and treatment. 3) Nearly all the clinical investigations such as history, physical exam, bronchoscopy, culture, and cytological exam of sputum sre likely to futile:the only tool for detecting the presence of the lesion is X-ray, butthat's short of telling the true nature of it. 4) Because of its age of presentation and growing tendency in middle-aged adult, it still controversial whether it is developmental anomaly as Albrecht described, or true neoplasm denovo of fibrous connective tissue origin. This is a case report of surgical experience of pulmonary hamartoma which had nearly all the typical clinical features above mentioned and was reviewed with related literatures.

The purpose of this study was to investigate elementary school pupil's classification ability that appears in classification activity. For this study, we developed 2 suitable tools in classification activity achievement. One is artificial stimulus card that comes into view clearly. The other is natural stimulus card that does not come into view well. The test was administrated to 376 pupils of 2, 4, and 6 grade in D elementary School in Yeongdeungpo-gu, Seoul. The result proved in this study was as following. First, elementary school pupil's classification ability showed the developmental change as the grade level rises. Second, there was no statistical difference between boys and girls. Third, there was high correlation between sort artificial category and natural category in their ability. Fourth, classification achievement rate of constant level by grade was seen regardless of the items. The findings above gives following guidance in science classification learning. First, if teacher understands the development of students' classification ability, more effective classification guidance is available. Second, to cultivate students' classification ability, we should devise and apply program depending on their classification ability by grade.
