This study examined the moderated effects of self-control on the relationship between elementary school children's excessive use of the Internet and their stress levels. The participants were 403 elementary school children from Chungnam-do. The instruments used were the 'Internet Addiction Autodiagnosis Scale (K-Scale)', the 'Stress Scale' and the 'Self-control Rating Scale'. The collected data were analyzed by t test, F test and the Scheffe test for a post hoc test, Pearson's partial correlation and stepwise multiple regression, and Cronbach's ${\alpha}$ for reliability by SPSS program (17.0 version). The results were as follows : First, it was found that there were significant differences in terms of excessive use of the Internet, stress levels, and self-control by gender, grade, academic achievement, the beginning year of first Internet access and the number of hours of Internet usage hours per day. Second, there were significant positive correlations between excessive use of the Internet (r = .40, p < .001) and stress levels (r = .44, p < .001) and the immediate satisfaction of self-control. Finally, the immediate satisfaction of self control was seen to moderate the relationships between the total scores for the excessive use of the Internet and stress levels and between withdrawal of excessive use of the Internet and the accompanying stress levels.

The Korean government has introduced land policy reform measures recently, in order to stabilize the circulating system of land, without a parent law involving effective land use. The measures aim to change the pattern of land market rather than the pattern of land use. Expecially, the excessive profits tax on land intends to redistribute the owernership of residential land, and to recapture windfall gains on an accrual basis. However, it may incur secondary gains in macro economics and an unintended reduction of urban land supply in the land market. This paper aims to study empirically the impact caused by the excessive profits tax on land, and to promote urban land supply. Ultimately, this paper can be regarded as an interim report on outcome of research projects which aim to propose a method of urban land supply suitable to an advanced society.

Objective ： We investigated the characteristics of cellular phone use and its association with psychological problems among adolescents. Methods ： A total of 332 adolescent students were recruited for this study. The participants' self-reported characteristics of cellular phone use and the psychological problems caused by this were tested by using the Excessive Cellular Phone Use Survey (ECPUS), the Children's Depression Inventory (CDI), Spielberger's State-Trait Anxiety Inventory for Children (STAIC) and the Korea-Youth Self Report (K-YSR). Results ： The excessive user group made more use of text messages and they spent more time and paid higher fees than the comparison group. They expressed severer depression and anxiety and they had more behavior problems and lower school performance than the comparison group. The ECPUS score was positively correlated with score of the CDI, STAIC and the behavior problem scales of the K-YSR, and the ECPUS score was negatively correlated with the school performance scale of the K-YSR. Conclusion ： Our findings suggest that excessive cellular phone use by adolescents may be related to psychological problems. Careful education about the use of cellular phones and intervention are recommended for adolescents who excessively use cellular phones.

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.

According to the aviation statistics, tail strike incidents and accidents are cyclic. Although many tail strikes occurred during takeoff, these are less than during landing cases. Many cases are related on human factors. In my opinion it is possible to analyze the causes of takeoff tail strikes to some extent. There are major casual factors of tail strike during takeoff such as; (1) Mis-trimmed horizontal stabilizer (2) premature rotation prior to $V_R$ (3) Excessive pitch up rate during rotation (4) Improper use of the flight director. Among these causes improper use of flight director is excluded in this paper because it is recommended that pilot should use flight director after airborne. So I analyzed the other three causes as following. Firstly, because mis-trimmed stabilizer is related to center of gravity(CG), the relationship between stabilizer and CG is reviewed. Secondly, concerned premature rotation prior to $V_R$ I reviewed the background of rotation speed($V_R$) establishment and analyzed theoretically what speed leads to tail strikes. Thirdly, concerning excessive pitch up rate during rotation I analyzed what excessive pitch up rate can decrease ground clearance while using FDR data.

Objectives: The purpose of this study was to explore the influential factors of family function, parent-child communication, and family satisfaction on Korean adolescents game use. Methods: The participants were 940 adolescents in Seoul. A structured questionnaire was used to collect data. The study variables were family function, parent-child communication, family satisfaction, and game use. Results: Game use was different by gender, age, time to spend in game during weekdays and weekend. Game use had significant negative correlations with family cohesion, family adaptability, communication with father, communication with mother, and family satisfaction. Multiple regression analysis showed that 20.3% of the game use was explained by gender, communication with mother, hours of playing games during weekdays, family adaptability, and hours of playing games during weekend. Conclusions: These results suggest that being male and lack of communication with mother, low family adaptability, game hours during weekdays and weekend can be potential risk factors for excessive game use in the adolescents, which should by considered in developing a prevention program for excessive game use focused on family factors.
