The purpose of this study was to identify the relationship between fixation and brain preference. Based on the hemisphere asymmetric theory and fixation, two hypotheses were articulated. They were: 1) Right-brain preference is negatively related to divergent fixation. 2) Left-brain preference is negatively related to convergent fixation. A self-reporting scale for measuring the brain preference with 42 items were developed for the study based on functional characteritics of left and right hemisphere. Samples were collected from 579 college students in K University. Regression analysis showed that right-brain preference was negatively associated with divergent fixation. In the relationship between left-brain preference and convergent fixation, mixed results were produced. Research implication were discussed at the end of the study.

Influences of convergent services on the overall industry has become noticeable. Various services are becoming to converge into a single platform because of ever-hanging needs of digital service users. However, few studies have investigated how users' perception of convergent services as well as the quality of experience that service users have while using the convergent services. Therefore, this study aims at identifying perceived patterns of convergent services by IPTV users, which is one of the representative convergent-ervice platforms. It also aims at identifying the impact of perceived convergence pattern on the relationship between goal congruency among individual services and the quality of user experience. Two empirical studies were conducted to accomplish the research goals. We have constructed two prototypes of convergent digital services in the IPTV environment and conducted controlled experiments to verify the research hypotheses. The results indicate that design similarities of two services substantially influence the perceived patterns of convergent services. It was also found that the perceived convergent patterns have significant moderating effects on the impact of perceived goal congruence upon the quality of user experience. This paper ends with limitations as well as implications of the study results.

In the Digital Convergence era, the center of social networking is moving into on-line space. This means also that space for public is moving into the on-line space. Along with this, spaces in commercial area, offered as attraction factors, are taking a role as a public space. So, this paper defines these spaces mentioned above as public space and the like. Liberal and affluent communication of Digital Convergence has caused in new spatial cognitions such like, constant social space, flowing space, temporary space, and multiple space. This means the hybridization of on-line and off-line space and the advent of public convergent space. However, it is on-line-centered convergence and has positive effects and negative effects on relationship. This paper suggests the optimization of public convergent space to solve the problems and make better a public space for relationship. For achieving this, social disclosure is grasped as the common way to start relationship both off-line and on-line, and it is proved that social disclosure has three characters such as self-presentation, corporeality, and subjectivity. Subsequently, the differences of the roles of off-line and on-line space are separated by each individual character. These are self-presentation of performance vs. storytelling, corporeality of embodiment vs. disembodiment, and self-subjectivity vs. inter-subjectivity. By recognizing that there are multilevel spectrums between the formers and the latters, this paper presents the direction of the spatial configuration of public convergent space which offers the right of manipulation of self-disclosure. It will be used for presenting the prototype of public convergent space.

The aim of this research is to describe lacunary ∆^m-statistically convergent sequences with respect to metrics on generalised metric spaces (g-metric spaces) and to look into the fundamental characteristics of this statistical form of convergence. Also, the relationship between strong summability and lacunary ∆^m-statistical convergence in g-metric space is established at the end.

이 연구는 지역사회복지기관 이용자를 중심으로 금융역량과 자아존중감 그리고 금전관계의 관계를 탐색하였다. 경험적 분석을 위해 서울, 경기, 충남의 지역사회복지관 및 지역자활센터 이용자 총 429명을 대상으로 설문조사를 실시하였다. 빈도분석과 구조방정식모형을 활용하여 분석을 수행하였으며, 주요 분석결과는 다음과 같다. 첫째, 소득수준이 지역사회복지기관 이용자의 자아존중감에 미치는 영향은 통계적으로 유의미하지 않았다. 둘째, 금융역량이 높을수록 자아존중감이 높았다. 셋째, 금전관계 문제가 심각할수록 자아존중감은 낮았다. 넷째, 금융역량이 자아존중감에 미치는 영향을 금전관계 문제가 부분적으로 매개했다.

In this paper, we introduce arithmetic ${\mathcal{I}}$-statistically convergent sequence space $A{\mathcal{I}}SC$, ${\mathcal{I}}$-lacunary arithmetic statistically convergent sequence space $A{\mathcal{I}}SC_{\theta}$, strongly ${\mathcal{I}}$-lacunary arithmetic convergent sequence space $AN_{\theta}[{\mathcal{I}}]$ and prove some inclusion relations between these spaces. Futhermore, we give ${\mathcal{I}}$-lacunary arithmetic statistical continuity. Finally, we define ${\mathcal{I}}$-Cesàro arithmetic summability, strongly ${\mathcal{I}}$-Cesàro arithmetic summability. Also, we investigate the relationship between the concepts of strongly ${\mathcal{I}}$-Cesàro arithmetic summability, strongly ${\mathcal{I}}$-lacunary arithmetic summability and arithmetic ${\mathcal{I}}$ -statistically convergence.

Quality of cut is strongly dependent on the cutting pressure, so this relationship can be identified by pressure measuring system. In this paper, the experiments presented were performed with the devised pressure measuring system and the laser cutting of STS 304. Convergent type and convergent-divergent type nozzle were used for pressure variation of the distance between nozzle and workpiece. In laser cutting of STS 304, 1.0 kW CO $\_$2/ laser used. The convergent type nozzle(1.0 mm diameter) pressured above 3 kgf/cm $\^$2/, the MSD(Mach Shock Disk) created, which caused the the pressure variations of the distance between nozzle and workpiece. The maximum cutting pressure exists in accordance with the variation of distance. In spite of far distance the maximum cutting pressure is achieved by using the pressure measuring system. The higher cutting pressure beneath the workpiece the less quantity of dross and the kerf width. Since the higher cutting pressure helps to remove the quantity of dross and to stop the exothermic energy into the material. The optimum laser cutting parameter of STS 304(2.0 mm thickness) with the convergent type nozzle(1.0 mm diameter)is 0.75 mm and 2.5 mm distance between nozzle and workpiece, 4 kgf/cm $\^$2/ cutting pressure. In 3.0 mm thickness case, 1.5 mm and 2.25 mm distance is achieved for good quality.

본 논문은 청소년의 인권존중과 학교적응의 융합적 관계에서 자아존중감의 매개효과를 검증하는 데 목적이 있다. 분석자료는 2016년 한국아동 청소년인권실태조사의 중학교 2학년 2,366명의 자료를 활용하였다. 구조방정식모형을 적용하여 모형 적합도를 검증하고, 부트스트랩을 적용하여 매개효과를 검증하였다. 분석결과, 연구모형의 적합도가 적합하였으며, 청소년의 인권존중과 학교적응의 융합적 관계를 자아존중감이 유의미하게 매개하였다. 즉, 청소년들이 인권존중 경험이 많을수록 자아존중감이 높고, 자아존중감이 높을수록 학교적응을 잘하고 있는 것으로 분석되었다. 본 연구 결과는 청소년의 학교적응도를 높이기 위해 교사에 대한 인권교육 강화, 인권존중과 자아존중감을 접목한 교육프로그램 개발 및 운영이 필요함을 시사한다.

본 연구는 빈곤가정 청소년의 공감능력이 청소년의 행복한 삶에 긍정적인 영향을 줄 뿐 아니라 보호요인으로써 작용할 수 있다는 점에 주목하여, 청소년이 학교사회복지사와의 관계를 중심으로 경험하고 있는 공감을 이해하고자 실시하였다. 이러한 목적을 위해서 학교사회복지사와 관계 경험이 있는 빈곤가정 청소년 10명을 만났다. 심층면접은 '학교사회복지사와의 관계에서 공감을 경험하는 것은 자기 스스로에게 어떤 의미였나요? 라는 질문을 통해 진행하였고, 수집된 자료는 현상학적 질적 연구 방법으로 분석하였다. 연구결과에서 확인한 주제는 친밀한 사람으로부터 도움 받기로 나타났고, 구성요소는 '공감대 형성 노력', '마음 이해', '도움'이었다. 빈곤가정 청소년들은 정서, 인지적 공감 뿐 아니라 실질적인 도움 행동을 통해서도 공감 받았다고 지각하고 있었다. 따라서 차후 학교사회복지사 뿐 아니라 현장 실천가들이 빈곤가정 청소년을 만날 때 다양한 공감 기술을 충분히 숙지하고 활용할 수 있어야 하고 향후 공감에 관한 다차원적인 연구 노력이 필요함을 제안하였다.
