The present study investigated the perceptual span(or the span of effective vision) of junior-high school students during reading Korean, using the material and the moving-window display change technique used in Choi & Koh(2009). The 8 different window sizes were used in the experiment. They were 3, 5, 7, 9, 11, 13, 15 characters in size and the whole line. Reading rate, number of fixation, saccadic distance, fixation duration were compared between each window-size condition and the whole line condition. Considering the pattern of eye-movement measures above, the size of the perceptual span of junior-high school students in Korean reading may be estimated to be 9 characters, that is 4 characters to the right and 1 characters to the left of the fixation.

Technology innovation of digital convergence in recent years of the media sector has produced a series of significant changes in journalist labor. This study analyzes how recent introduction of convergent newsroom changed the nature of journalist labor and what strategy the management used to control journalists within the technologically innovated working condition with case of CBS. As the labor process theory tells us, the analysis found that technological innovation in the newsroom has encouraged a couple of aspects regarding labor process. First, losing control over their own labor journalists have undergone the process of significant deskilling. Second, the management have made a constant effort to introduce ideological and political apparatuses with twofold purposes, effective control over workers on one hand and concealing oppressive labor conditions on the other. The effort generated journalists' acceptance of new news-making routine and their consent on labor-management culture founded upon naive familism, which at last resulted in reinforcement of corporate power and isolation of labor society by separating internal labor market.

In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.

This study was conducted to determine the levels of job stress, as well as its association with psychosocial factors (type A behavior pattern, locus of control, and self-esteem). Self-administered questionnaires were given to 634 clerical public officers in the C Provincial Office between February 18 and Mar. 10, 2013. As a result, the job stress levels of the subjects was significantly different according to age, sex, educational level, marital status, job position, job career, satisfaction in job life, smoking, alcohol drinking, sleeping time, type A behavior pattern, locus of control, and self-esteem. Regarding the correlation of job stress and psychosocial factors, the level of job demand was negatively correlated with the internal locus of control. The decision latitude was negatively correlated with the type A behavior pattern, internal locus of control and self-esteem. Supervisor support was negatively correlated with the external locus of control. In hierarchial multiple regression analysis, the affecting factors to the job stress selected variables, such as age, subjective health status, job position, overtime work, experience of sick absence, satisfaction in work, sleeping time, leisure time, visiting out-patient department, type A behavior pattern, locus of control, and self-esteem, and the explanatory powers of these factors was 32.1%. In particular, the factors related to the psychosocial factors (type A behavior pattern, locus of control, self-esteem) were strongly related to the job stress, increasing the explanation of factors up to 15.0%.

It is widely recognized that human beings have moral responsibility for their actions because they have free will to choose and control their acts. Unlike natural phenomena, however, human acts cannot be interpreted with simple, visible ones. Human acts are quite different from natural phenomena because they come about through a number of complicated, invisible phases taking place in our mind. In addition, human actions are under the influence of internal and external factors. Those various internal and external factors are divided into four sectors as follows; (1) the factors that can fall under control of our free will, (2) the factors in the interim phase that could come under our control, (3) the factors that are partially determined that we cannot choose or control over, and (4) the factors that completely determined, and can't be chosen or controlled. we have to pay attention to the fact that we can choose or control the internal and external factors that influence human action. However, there are still factors that are impossible to choose or control with our will. So it is highly unreasonable to hold accountable for actors by means of the factors that can't be chosen or controlled. Hence, the society should be also accountable for the acts of actors influenced by heredity and environment. For this, Politics should affect the external, undesirable, and uncontrollable factors beyond actors power. Education has to exert its influence over the internal and genetic factors by instilling sound values in human mind, too. It is because happy and desirable future will be possible by giving equal opportunities to us including the youth.

This study recognizes that the externalizing problem behaviors of child with disabilities are the result of the social interaction between mother and child, and empirically verifies its systematic causal structure and multidimensional influence relationship. It was attempted to derive practical implications that can help the smooth normalization process of children's families. Therefore, 135 children with disabilities and their mothers selected by convenience sampling were targeted, and in the relationship between maternal overprotective parenting and externalizing behaviors of child, effortful control was used as a mediating variable, and defense style of mothers and children was used as a moderating variable. A Conditional Process Analysis(CPA) that can verify the moderated mediation Effect was performed by establishing a research model. As a result of the analysis, first, the overprotective parenting behavior of mother was statistically significant in both direct and indirect effects in increasing externalizing behaviors of child, and the mediation effect by effortful control was also statistically significant. Second, it was confirmed that the moderated mediation effect of effortful control by the mother's defense style was statistically significant, and the moderated mediation effect of effortful control by the child's defense style was not statistically significant. Based on the above results, assuming the importance of the influence of maternal parenting, a direct strategy for change in maternal overprotective parenting, child's Practical implications of parallel strategies with the tendency toward effective control and suboptimal strategies through the application of mothers' coping strategies were discussed.

화력장비혁명의 내용을 알려면 단순히 정밀유도무기나 레이저 유도무기군만을 볼것이 아니라 전반적인 화력장비 차원에서의 잠재력을 살펴야 한다. 화력장비의 성능은 감시능력, 목표식별, 목표포착, 발사계획 및 조종통제, 파괴력 그리고 각 구성체계간의 신뢰성 있는 통신 능력에 달려있다. 이러한 기반위에서 각 요소들은 계속 기술적으로 발전하고 있다. 우리는 컴퓨터나 발전된 통신기술에 의해서 우선적으로 가능하게 된 자동전투관리시스템(ABMS)의 발전을 생각해야 한다

DMZ권은 지난 반세기 동안 출입이 통제된 덕분에 다양한 생물종의 서식공간이자 생명벨트로 형성되어 있다. 서부 DMZ권에는 한강 하구와 임진강 유역의 성동 습지와, 장단 습지, 문산 습지, 임진각 습지 및 초평도 습지가 있으며, 이곳에는 멸종위기종 1급인 황새, 노랑부리저어새, 저어새 등 8종과 2급인 큰고니, 개리 등 21종, 황조롱이, 매, 흑두루미 등 천연기념물 22종이 서식하고 있다. 본 연구에서는 서부 DMZ권을 중심으로 현지 조사를 통해 하천환경과 습지 현황을 조사하였다. 임진각 습지는 임진강의 건천화 때문인지, 아님 썰물 때문인지 유량은 그리 많지 않았다. 덕분에 갯벌이 많이 드러나고 재두루미와 개리 등이 눈에 뜨였다. 장단반도는 절반은 농경지, 절반은 갈대 군락지이다. 군락지에는 갈대뿐만 아니라 달뿌리풀, 갯버들도 서식하고 있었다. 농경지에는 재두루미 가족이 섭식하고 있고 임진강에는 기러기 약 2천 이상이 발견되었으며, 고라니도 다수가 조사되었다. 최근에는 136마리가 조사되었다. 초평도의 습지에서는 물새가 탐조되었다. 습지는 생태계의 훌륭한 서식처의 역할을 하며, 수질 개선과 기후 조절 기능도 갖고 있으며, 생태 관광에도 기여를 하고 있음이 밝혀졌다.
