Objective: The purpose of this study was to examine the mediating effects of smartphone addiction tendency on the relationship between depression of mothers with 3 to 5 year-old children and rejecting-neglecting parenting style. Methods: Three hundred and twenty-eight mothers answered questionnaires on three research variables. To analyze the data, Pearson correlation analyses and regression analyses were conducted. Results: First, mothers' depression, smartphone addiction tendency and rejecting-neglecting parenting style showed positive correlations, respectively. Specifically, mothers with a high level of depression were more addicted to smartphones and exhibited more rejecting-neglecting style of parenting. Also, mothers who were more obsessed with smartphones showed more rejecting-neglecting parenting style. Second, this study found partial mediating effects of smartphone addiction tendency on the relationship between depression and rejecting-neglecting parenting style. Conclusion/Implications: This study confirmed that mothers' depression and smartphone overuse had an influence on their negative parenting behaviors. The results of this study address the need of various interventions for mothers to decrease their depression and smartphone overuse.

Objective : The objective of this study was to examine the association between childhood adversity and parenting attitude and neuroticism in adulthood. Methods : Forty nine women were recruited from community and completed Early Trauma Inventory-Short Form (ETI-SF). We compared scores on the Maternal Behavior Research Instrument (MBRI), Neuroticism of NEO Personality Inventory (NEO-PI), and Beck Depression Inventory (BDI) between women with and without childhood adversity. Results : Compared to women without childhood adversity, women with childhood adversity showed more rejecting parenting attitude and higher Depression and Self-Consciousness scores on Neuroticism domain of NEO-PI. Total ETI-SF scores and emotional abuse scores were positively correlated with rejecting attitude scores on the MBRI and BDI scores. Physical abuse scores were positively correlated with rejecting attitude scores. There were positive correlations between rejecting attitude scores on the MBRI, Neuroticism scores on the NEO-PI, and BDI scores. Conclusion : Our results suggest that childhood adversity may have a negative impact on parenting attitude and emotional state in adulthood. For girls who experienced traumatic event, early intervention is needed to prevent the development of neurotic temperament and rejecting parenting in adulthood.

본 논문에서는 고속의 전력용 반도체를 이용하여 직류-교류 전력변환을 행하는 전압형 PWM 인버터에서 발생하는 영상전압을 억제할 수 있는 회로시스템을 제안한다. 제안된 시스템은 영상전압과 크기가 같고 역위상의 전압을 발생하여 이를 영상전압 억제용 변압기를 거쳐 인버터 출력에 중첩함으로써 부하에 인가되는 영상전압을 억제하였다. 이로 인해 영상전압분에 의해 접지선으로 흐르는 고조파 누설전류의 감소효과를 가져왔고, 이에 대한 타당성을 시뮬레이션을 통하여 확인하였다.

The purpose of this study was to compare beliefs about social rule, differential peer association, perceived behavioral control, intention of smoking, and self efficacy for rejecting smoking among smokers, reformed smokers, and non smokers in adolescence. The subjects were 576 adolescents in middle and high school, living in K city. The data was collected through questionnaires from December 1st to 18th, 2002 was analyzed using descriptive statistics, x²-test, and ANOVA. 1) The general characteristics and characteristics related to smoking among smokers, reformed smokers, and non smokers in adolescence showed differences as follows： sex, mother's education, monthly allowance, thinking about teacher's smoking, feelings about the smoking scene, thinking about father's smoking, drinking, satisfaction of school, and sexual experience. 2) Belief about social rule, differential peer association, perceived behavioral control, intention of smoking, and self efficacy for rejecting smoking among the three groups showed differences as follows： smokers have a lower belief about social rule, lower perceived behavioral control, lower self-efficacy for rejecting smoking, but higher differential peer association and higher intention of smoking than those of reformed smokers and non smokers. We recommend the development of a nursing program for anti-smoking behavior including the research factors affecting attitudes of smoking adolescents.

This paper proposes a permanent magnet synchronous motor(PMSM) control using a repetitive controller. Repetitive controllers are often used to eliminate periodic disturbances. Based on this, it is possible to alleviate the torque disturbance occurring at a constant cycle to the load of the motor. This paper proposes a method of rejecting periodically generated disturbances by using a repetitive controller and verified by simulation.

In this study, the influence of mothers' parenting behaviors on children's strategies and competence of emotional regulation was examined. Further, the mediating effects of children's active-social support seeking and aggressive strategies on the above relationship were explored. The participants were W mother-child pairs. The children were 5th and 6th graders at two elementary schools in Kyunggi province and Kwangju metropolitan area The data were analyzed with descriptive statistics, factor analysis, Cronbach's alpha, Pearson correlations, standard multiple regressions and structural equation modeling analysis by LISREL 8.3. The main results of this study were as follows: (1) The more the mothers coached children with affection and reasoning, the more adaptive emotional regulation the children had; whereas children tended to have maladaptive emotional regulation in response to the mothers' rejecting and forceful parenting behaviors. Also, when children were coached by mothers with love, reasoning and consistent restriction, they used more active-social support seeking strategies, whereas they used more aggressive strategies when the mothers coached children with rejecting and forceful parenting behaviors. The more the mothers were rejecting, forceful and intervening, the more the children used passive-avoidant strategies. (2) The more the children used active-social support seeking strategies and the less the children used aggressive strategies, the more likely they had adaptive emotional regulation. The more the children used aggressive strategies, the more likely they had maladaptive emotional regulation. (3) Children's active-social support seeking strategies played a partial mediating role between mothers' affectionate and reasoned coaching and children's adaptive emotional regulation. These strategies, on the other hand, played a full mediating role between mothers' consistent restriction and children's adaptive emotional regulation. Children's aggressive strategies played a partial mediating role between mothers' rejecting and forceful parenting behaviors and children's maladaptive emotional regulation. Mothers' non-intervention had an influence on neither the children's aggressive strategies nor their maladaptive emotional regulation.

이 글은 선유(先儒)들의 묵가에 대한 비판을 개괄하고, 이를 전제로 하여 고려말부터 시작하여 조선조 후기에 이르는 묵가 비판의 전개 양상을 고찰한 것이다. 우리나라 고려 이전의 문헌에서는 묵가나 묵자를 비롯한 제자백가를 명시적으로 배척한 사례가 보이지 않는다. 여말선초에 이르면 성리학의 수용과 더불어 맹자의 벽이단론의 관점이 부각되기 시작하면서 양주와 묵적에 대한 비판을 전제로 불교와 노자를 배척하기 시작하였다. 조선조 지식인들의 묵가에 대한 이해와 비판 양상의 특징은 묵가의 이념 자체에 대한 비판보다는 주로 다른 이념이나 부조리에 대한 비판의 도구로 활용되었다는 것이다. 여기에는 여말선초의 불교와 노자, 중후기의 문장학(과거학), 서학(천주교), 나아가 관료들의 부패 등이 포괄된다. 내용면에서 본다면, 묵가의 십대 주장 가운데 「겸애」와 「절용」(절장, 비악)에 대한 비판이 주를 이루고 있으며, 조선 중후기에 이르면서 「명귀(明鬼)」와 「천지(天志)」에 대한 비판이 포함되고 있다. 주목할 만한 점은 중국사상사에서와 마찬가지로 침략전쟁을 반대하는 평화 이념이 반영된 「비공(非攻)」이나 운명론을 부정하는 「비명(非命)」에 대한 비판은 보이지 않는다는 것이다. 이것은 유가의 인문주의적이고 현실주의적 측면에서 볼 때 적극적으로 비판할 여지가 없었던 데 연유하는 것으로 생각된다. 한편 묵가 이념과는 별도로 묵자 개인의 묵수(墨守)와 관련된 행위에 대해서는 대체로 긍정적인 평가를 하고 있다. 또한 후기에 이르면서 묵자서는 이념서가 아니라 유교 경전 내용을 고증하기 위한 사료로서 활용되고 있음을 확인할 수 있다.

The scientific inquiry enterprise consists of formulating hypotheses, testing hypotheses, evaluating evidence, and revising hypothesis. Scientific inquiry in the science classrooms requires students' background experience and knowledge with the phenomenon in order to ask appropriate questions, identify and define variables operationally, formulate hypotheses, and design clear and complete experiment. The ability to test hypotheses has been postulated to play a central role in cognitive processes. The purpose of this study was to analyze what the change of the quantity and quality of the hypothesis, the rejecting or accepting of the hypothesis, and the use results in the repetitional hypothesis activity experiments. To examine the problems, this study analyzed 5 classes which were designed and administered to 16 students of the 7th grade. The results of this study showed that students preferred the engineering method to scientific method and the quality of a second hypothesis got low. The quality of the hypothesis came to be higher through a repetitional hypothesis and the number of hypothesis was reduced. The results of the experiments did not play central roles in revising hypotheses and accepting or rejecting hypothesis.

When we measure electrical impedance of a small object, such as an electronic component, external interference or jamming signal can be rejected by shielding the object. However, when we measure impedance of a large object, such as a human body, shielding is not easy and severe error due to the external interference could be introduced. In this paper, spread spectrum technique applicable to bioimpedance measurements for rejecting external interference without shielding is introduced. The improvement in signal-to-jamming ratio by the spread spectrum technique was experimentally confirmed.

The wave concept iterative procedure (WCIP) is used to analyze a quasi-square open metallic ring frequency selective surface (FSS). The quasi-square open metallic ring FSS is dual-polarized. When the incident plane wave is polarized in a direction parallel to the FSS' coupled parallel strips, it shows two rejecting bands. Moreover, another rejecting band can be obtained if the source plane wave is perpendicularly polarized with respect to the FSS' coupled parallel strips. The three resonant frequencies are inversely proportional to the length of the FSS' coupled strips to provide an easy fine tuning of the FSS structure. The simulated results obtained using WCIP are compared to the measured results, and a good agreement is reported.
