본 논문에서는 기존의 매개변수들과 달리 화자의 고유한 특성을 보여주는 화자인식 매개변수를 발성유형에서 찾고자 한다. 일반적으로 화자의 음원 특성이 발성 유형을 결정한다. 발성유형의 특성을 나타내는 매개변수로는 개방지수(open quotient)와 스펙트럼의 기울기 (spectral tilt)가 있으며, 스펙트럼의 기울기는 음향학적으로 그 특성을 측정할 수 있다. 그러나 기존의 측정방식은 사람마다 다른 기본 주파수와 모음의 영향을 전부 혹은 일부 배제하지 못하였다. (중략)

The purpose of this study was to investigate the relation among father's child-rearing involvement, father-child communication style, children's achievement motivation and school adjustment. The subjects were 236 - 5th and 6th graders of elementary schools in Daegu. The major findings were as follows: first, children's achievement motivation was affected by father's child-rearing involvement. Second, children's achievement motivation was affected by father-child communication style. Third, children's school adjustment was affected by father's child-rearing involvement. Fourth, children's school adjustment was affected by father-child communication style. Fifth, children's school adjustment was affected by achievement motivation. Sixth, father's open communication style was the most important variable to teacher adjustment compared to other variable. Children's achievement motivation was the most important variable to peer adjustment compared to other variable. Father's leisure activity involvement was the most important variable to school education adjustment compared to other variable. Children's achievement motivation was the most important variable to school rule adjustment compared to other variable.

The purpose of this study is to analyze parental gatekeeping dimensions(control, encouragement, discouragement) and types of gatekeeping in the two families featured in the drama 「SKY Castle」. Of the 8 types of gatekeeping, the traditional gate blocker(high control, low encouragement, and high discouragement) most often described in the drama, creates a difficult situation for a father trying to participate in child rearing. But traditional gate blockers do not always unnecessarily limit father involvement. In father's coerecive and dictatorial environment, traditional maternal gatekeeping strategies protect her children and create secure environment. The facilitative gate openers(high control, high encouragement, and low discouragement) is the functional gatekeeping type. Because the mother's highly controlling and highly encouraging ways serve as a positive coparenting strategy, the facilitative gate maintain a high level of authority over the amount and type of father involvement.

This paper documents the increase in earnings variability (or earnings risk) during the 1990s in Korea, and investigates whether it can be accounted for by capital market opening. The variances of transitory and permanent innovations in earnings are estimated from repeated cross-section data using a simple econometric framework. The increasing time-series pattern of earnings risk among men follows the increased foreign capital presence reasonably well, but the supporting cross-sectional evidence for a causal relationship between the two is weak. However, foreign direct investment (FDI) is found to have had some non-neutral effects on workers of varying skills in such a way that transitory earnings risk of less-skilled workers relatively increased with FDI. To the extent that transitory innovations are not fully insured, this widening effect of FDI on earnings risk gap may have contributed to widening welfare gap between skilled and unskilled workers in Korea, at least in terms of "risks."

This study is aimed at articulating the policy communication concept and developing the policy communication index between the Korean government and the public. Theoretically guided by dialogic communication theory, two step research was employed. In the first stage, the elements of policy communication were derived through literature review and in-depth interviews. In the second stage, online survey was conducted for the general public and reliability and validity were secured through confirmatory factor analysis and structural equation model analysis. The finalized policy communication index has two dimensions of mutuality and openness. The mutuality has six sub dimensions and the openness has three sub dimensions. The level of mutuality and openness of the policy communication index differed according to the policy type. In the cultural policy, which represents the traits of distribution policy, the degree of mutuality was strong, but the degree of openness was important in communication of education policy, which represents the traits of redistribution policy. This study is meaningful as an empirical study that verifies and suggests the influence of the policy communication index in the context of the policy communication and practical applicability to strategic public relations by understanding the dimensions of policy communication.

The purpose of this study was to investigate if students may actually experience scientific reasoning based on an epistemology of authentic science during authentic open inquiry. The samples were 86 10th graders in a science-high school in Seoul. The experimental group practiced authentic open inquiry and the control group practiced traditional school science inquiry in five weeks. Then, the questions students asked while performing inquiry tasks were analyzed. The frequency of the questions asked by students was almost same between two groups, however, the types of questions were different. The frequency of thinking questions in experimental group was higher than the control, and the difference was statistically significant (P<.01). Particularly, the frequency of expansive thinking questions and anomaly detection questions was much higher in experimental than the control group. Judging from the result, with the students from the experimental group asking questions reflecting on the epistemology of authentic science such as scientific methods, anomalous data, and uncertainty about reasoning, students may understand authentic science features during the activities of open authentic inquiry. The result from comparing questions according to the inquiry subject showed that more openness caused the higher frequency of anomaly detection questions and strategy questions, but that inductive thinking questions and analogical thinking questions were connected to inquiry subject rather than the openness of the inquiry.

모바일 네트워크 고도화 및 단말기의 비약적인 발전으로 스마트폰 보급이 확산되고, 스마트폰 시장의 경쟁 본격화에 따른 개방형 플랫폼 증가와 애플리케이션 마켓플레이스의 활성화가 이뤄지고 있다. 개방형 모바일 환경에서는 표준화된 개발환경이 모든 개발자에게 공개되어 있어 누구나 애플리케이션의 제작 및 배포가 가능하기 때문에 질적으로나 양적으로 모바일 애플리케이션이 등장할 것으로 예상 된다. 하지만, 개방화된 개발환경의 등장과 더불어 범용 OS를 채택하고 있는 모바일 단말은 모바일 악성코드의 제작을 용이하게 만들고, 제작된 모바일 악성코드는 범용 OS로 인해 이식성이 높기 때문에 모바일 공격의 규모 및 피해가 증가할 것으로 예상된다. 본 논문에서는 개방형 모바일 환경에서 제공되는 스마트폰 기술 및 시장 전망, 모바일 위협의 종류 및 유형, 그리고 이러한 위협에 대응하기 위한 보안기술에 대하여 살펴보고자 한다.

The purpose of this study was to investigate the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles. The subjects were 399 middle school students and 366 high school students in four middle schools and two high schools in metropolitan and small towns for one month from July 1, 2017. Data were analyzed through descriptive statistics, correlation analysis. Multiple regression was used to see how parent-adolescent communication styles, self esteem, and depression affect the career decision-making style. As a result, first, open communication with mothers has a statistically significant effect on the rational career decision-making style and open communication with fathers has a statistically significant effect on the intuitive career decision-making style of adolescents. Second, self-esteem of adolescents showed a positive correlation with rational career decision-making style and negative correlation with dependent career decision-making style, and depression showed a positive correlation with dependent career decision-making style. The results may help to understand the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles and be used for counseling intervention.

This study analyzes the correlation between the library anxiety and personality traits. The library anxiety (LAS) and personality traits (the Korean BFI) were measured against 49 freshmen in the university. The library anxiety was average 2.57, 'mechanical barriers' score was the highest(2.91), subsequently was 'affective barriers' 2.72, 'barriers with staff' 2.49, 'knowledge of library' 2.42, and 'comfort with the library' score was the lowest(2.38). The personality traits had the tendency that 'agreeableness'f actor(3.65) is higher than other 4 factors, 'neuroticism'(3.48), 'extraversion'(3.27), 'openness'(2.85), and 'conscientiousness' (3.26). It found that 'comfort with the library' and 'neuroticism' were correlated statistically and the personality traits have an effect on library anxiety. Based on the findings, the following recommendations are made: improving the measurement tool of information anxiety, using other personality traits variables in similar researches, and developing personalized library anxiety resolution programs.
