인터넷 중독 성향을 보이는 청소년들에서의 기질성격 특성

Objectives : Recent studies have focused on characteristics of adolescents who use internet addictively. Due to many ambi-guides in the definitions of internet addiction, it is hard to find a tool for diagnosing internet addiction. In this study, we attempt to identify the temperamental characteristics of adolescents who have addictive internet using patterns by administering a newly developed internet addiction scale based on a psychometric technique and temperament and character inventory (TCI) based on Cloninger's psychobiological model. Methods : Participants were 566 high school students. 478 students were recruited from high schools, and 88 were selected from internet cafes. We applied the internet addiction scale and TCI. All the students were divided into 3 groups (high risk user group, Potential risk user group and normal user group) according to the results of the internet addiction scale. TCI scores were compared and analyzed according to the participants' characteristics. Results : There were significant differences in the distribution of internet user group according to gender. Boys had higher percentage of high risk and potential risk users than girls. When each TCI score was compared according to gender, girls showed significantly higher harm avoidance, reward dependence, cooperativeness scale scores and lower persistence, self-transcendence scale scores than boys. TCI scores were compared among the internet addiction risk user groups. Risky internet users showed lower scores in reward dependence, self-directness and cooperativeness dimensions than normal internet users. Conclusion : There was a gender difference in internet addiction hsk in this study. These results suggest that adolescents who use internet addictively also have higher tendency of problematic social and interpersonal relationship. These tendencies need to be considered as one of the important aspects of internet addiction. This study shows that assessment of temperament and character in adolescents who have problems related to the internet may be needed for understanding their addiction behaviors and underlying psychopathologies.

본 연구는 關口等(1980) 에 의하여 제안된 彈·粘塑性 構成方程式을 선정하여 盛土荷重을 받 고 있는 軟弱地盤의 샌드드레인에 대하여 有限法要素法에 의한 數値解析을 수행하는데 그 目的이 있다. 韓國西南海岸의 大部分은 軟弱地盤으로 이루어져 있기 때문에 建設工事를 하는데 壓密이 라는 심각한 문제가 야기된다. 이와 관련해서 본 연구에서는 事例檢討로서 西南海岸의 于拓과 工業團地造成事業과 관련된 設計와 施工管理 資料를 確保할 수 있는 方案도 강구된다. 또 이 연구에서 개발된 電算 프로그램의 粘度와 그 實用性을 확인하기 위하여 光陽製鐵所敷 也 造成工事 現場의 實觀測徝와 數値解析結果를 비교한 바 兩者가 잘 一致하고 있음이 발견된 다. 이 結果로부터 盛土工事의 最適化도 기대할 수 있게 되었으며 分析된 主要結論을 要約하면 다음과 같다. 1. 彈·粘塑性 構成모델은 이 연구에서 대상으로 한 粘性土地盤의 壓密解析에 適合하다고 立 證된다. 2. 數値解析에 의하여 地盤改良의 効果와 施工速度를 豫側할 수 있다.

This paper treats the deformation characteristics rather than the shear ones. On the reconsolidated and remoulded saturated clay sampled from the downstream of Yeongsan river in Cheollanamdo, it is investigated that the prediction of strains will be possible based on the theory considering the effect of dilatancy among the several prediction theories1) developed so far through the undrained and drained triaxial compression test. The conclusions analized are as follows. 1. It is confirmed that the stress paths obtained from the undrained triaxial test with constant cell pressure are similar one another. and state path normalized with Pe (mean equivalent pressure) is overlapped on the same locus. 80 that there exists a unique state path on the specimens used in this experimental study. 2. The volumetric strain due to the model based on the characteristics of the dilatancy effects is similar to the experimental observation. 3. Thè prediction of shear strain due to both the incremental theory and the volumetric strain2) is similar to the experimental observation.

An exceedingly rare case of perforated early gastric cancer is reported. A 68-year-old man developed a peritonitis due to perforation of early gastric cancer. Emergency radical operation was performed and followed by uneventful recovery. The histologic examination of the surgical specimen showed early gastric cancer of typeⅢ, composed signet ring cell carcinoma. 5 years of surgery, the patients survived with no evidence of tumor recurrence. The rarity of this complication in early gastric cancer is discussed and the literature reviewed.
