A game designer is the initial design of the quest based on narrative. It is important that to predict game character of play experience to establish these static content. This paper deal with player's affective interaction distinguishing among game characters are perform quest-play based on their characteristic status. To achieve this, First of all, previous studies regarding pre-visualization of narrative structure for other visual media are reviewed. Secondly, it is specified that quest-play experience and player's cognitive behavior. At last, these features of status by character were pre-visualized with QUG(Quest Unit Graph), which could be represented differences in precess of quest-play through analysis on world of warcarft game. Previous research is about of numerical balance in terms of character's achievement, whereas this study is meaningful that is proposed that visual model of quest-play interaction focused on narrative structure to predict game designer's architecture of quest experience.

The microsurgery of the laryngeal lesions was introduced by Kleinsasser in 1965. This has been utilized for diagnosis, surgical management and education of the laryngeal lesions. The laryngomic-roscopic technique appear to be useful in the evaluation of the lesions which may be precancerous, since minor degrees of epithelial thickening and alterations in the pattern of fine vessels beneath the epithelium may be observed with greater clarity. With suspension laryngoscopy, the authors experienced 11 cases of the laryngeal lesions: polyp (4 cases), web formation between false cords and true cords (1), papilloma (4), laryngeal trauma (1), and squamous cell carcinoma (1).

The high rates of smartphone usage among younger people and the negative impacts are well-known, but there remains a paucity of qualitative research on the topic. This study was designed to explore the experiences of university students addicted to smartphones. The author conducted in-depth individual interviews with 17 university students who scored in the upper 5th percentile on a smartphone addiction scale. All interviews were audiotaped, transcribed, and analyzed using qualitative content analysis. Students with a smartphone addiction were trapped in a vicious cycle. More specifically, they were "Realizing something was wrong with withdrawal symptoms," "Having negative consequences," "Seeking escape," and "Staying addicted." This study helped participating students realize their addiction and disclose their emotional and interpersonal difficulties related to their smartphone use. These understandings may be used to refine and further develop school-based programs to better help those addicted to smartphones to recover.

The purpose of this study is to develop a substantive theory that understand the burnout and secondary traumatic stress experience of social workers who worked in the trauma centers. This research was conducted by Grounded Theory. The result is as follow: In the initial coding, 159 units of mean, 47 subcategories, and 12 main categories. The central phenomenon of the initial coding was 'the wounded existence.' In the focused coding, the core category was 'seeking to recover professional identity as a social worker.' In the theoretical coding, the burnout and secondary traumatic stress experience of social workers who worked in the trauma centers were classified as four phases;'Commitment to the mission', 'Conflict', 'Stagnant' and 'Disruption'. Based on the findings, the preparation for the disaster social work practice, the perspective on "social healing" of trauma, and the necessity of the mandatory policy or intervention for social workers self-care were discussed.

수력발전 사업에 있어 Desander 구조물은 주로 고산지대 수력발전댐의 Run-of-river 형식의 발전방식에서 유사로 인한 터빈의 손상을 방지하기 위한 목적으로 설치된다. Desander의 적정 규모는 터빈의 손상을 일으킬 수 있는 유사 입경에 대해 안정적으로 침전을 시킬 수 있는 폭/길이/깊이로 평가할 수 있으며 상대적으로 Desander의 규모가 크게 설계된 경우 초기 공사비 증가하고 반대로 규모가 작게 설계된 경우 터빈의 교체 주기 단축으로 인한 유지관리비가 증가된다. 현재까지 일반적인 Desander 구조물의 설계 방식은 제거 입경의 침전 속도, 유입유량 및 깊이를 변수로 사용하여 경험식(L. Sudry method, Guicciardis method 및 Rouse method)을 통해 규모를 결정해 왔다. 하지만, 3-D 전산유체해석을 통해 유속 흐름 분석으로 직 간접적 Desander 규모의 적정성을 평가할 수 있는 현 시점에서 경험식으로부터 도출된 결과의 신뢰성과 객관성을 검증할 필요가 있다고 판단된다. 본 연구에서는 노르웨이 NSTU에서 개발한 유사의 이송 및 확산해석 기능이 내장된 범용 소프트웨어인 SSIIM을 이용하였다. SSIIM(Simulation of Sediment movements In water Intakes with Multiblock)은 개수로 흐름 상태에서 유사 이동 및 하상 변동을 분석할 수 있도록 개발된 3-D 해석 프로그램이다. SSIIM은 수치해석 방법으로 유한체적법(Finite Volume Method)를 채택하였으며 Navier-Stokes equations을 통해 유체의 흐름을 해석한다. 입력 자료는 유입 유량($m^3/sec$), 유입 유사량(kg/sec), 유출부 수위 및 해당 Desander Structure grid 자료가 사용되며 해석 결과로 Desander 내 grid 별 유속, 수위, 유사 농도 변화 등을 제공한다. 본 연구에서는 SSIIM을 이용하여 제거 목표 유사 입경의 차집 효율(Trap efficiency)로 Desander의 적정 규모를 평가 할 수 있는 설계법을 제안하며 설계 단계에서 결정되는 최소 제거유사 입자와 차집 효율에 의한 Desander의 적정 규모 평가 분석을 파키스탄 A 프로젝트를 대상으로 수행하였다. 연구 성과로 (1)SSIIM을 통해 해석된 차집 효율을 기초로 Desander의 적정 규모를 계획할 경우 경험적 방식에 비해 설계의 객관성과 신뢰성을 제고할 수 있으며 (2)3-D 수치해석을 통해 grid 별 유사농도를 확인 할 수 있어 Desander 형상과 규모에 대한 평가가 가능하다.

This study is intended to develop a numeracy program for late-adult learners. For this study, firstly, characteristics of numeracy were analyzed and based on those characteristics, numeracy learning contents for late-adult learners were selected. Also, teaching and learning materials were developed by linking the mathematics contents selected to experience-based real lives of late-adult learners. When this numeracy program was applied to late-adult learners, it was observed that there was a change in the affective domain like interest at the early stage of learning and that as learning continued, mathematical elaboration occurred by way of mathematical formalization. In conclusion, this study has significance by re-defining arithmetic for late-adults from a perspective of numeracy, based on experience of late-adults, and making a contribution to mathematical elaboration of late-adult learners so non-formal problem-solving processes of lat-adult learners can be justified as elaborate mathematical problem-solving.

This study involved an investigation of prospective elementary teachers' preconceptions and experiences of diagrams and their ability to draw diagrams in solving math word problems. A questionnaire and two math word problems were administered to prospective elementary teachers who began to taking an introductory mathematics education course. The results from the analysis of their responses to the questionnaire items indicate that prospective elementary teachers appreciate the value of diagrams as tools for problem solving and communication. In addition, prospective elementary teachers have the will not only to teach their future students how to use diagrams but also to encourage them to draw diagrams in solving math word problems. However, the results also indicates that prospective elementary teachers neither use diagrams spontaneously in their math problem solving activities nor have confidence in drawing useful diagrams. Prospective elementary teachers also manifested low scores on the questionnaire items asking whether they were taught how to draw useful diagrams or encouraged by their teachers to use diagrams in their previous learning experiences. The results from the analysis of the diagrams that prospective elementary teachers drew in solving math word problems showed that most of them had difficulty drawing diagrams that represent their reasoning and solving process.

This study investigated the effect of cognitive dissonance that people experience during online communication on face-to-face communication. When people communicate with others on Interne using the comment system, they know that all the people including themselves equally participate in the discussion as one of the many commenters. At the same time, they somewhat distrust other commenters' attitudes because of the Internet anonymity. We name this seemingly contradicting beliefs as cognitive dissonance and examine how these beliefs affect the intention to communicate in face-to-face. Also, the proposed research model includes other factors such as curiosity and the differences in attitudes between online and offline. To verify the hypotheses, a total of 323 comment system users were recruited and show that most of the hypotheses were supported. This study emphasized its implications by examining the reasons when and why people prefer direct communication rather than comment based communication.

This paper presents results of an experimental study designed to investigate the effect of sustained load on the flexural performance of reinforced recycled aggregate concrete beams. In this experimental program, three beams with recycled aggregate replacement percentages(natural 100%, recycled coarse aggregate 100%, recycled fine aggregate 50%) were tested up to failure after sustained loading($0.5M_n$) for one year. The experimental results showed that reinforced concrete beams using recycled aggregate(water absorption : 1.86~3.64%) concrete showed the same flexural performance as that of natural aggregate concrete beam. Current the ACI code underestimated experimental obtained ultimate flexural strength of beams irrespective of usage of recycled aggregates.

우리 나라에서 초등영어 교육이 실시되는 연령층이 언어습득 분야에 있어 그렇게 일찍 언어학습을 시작하는 것이 학습효율성의 측면 또는 언어숙달도 측면에서 과연 이로운지에 관해서는 학자들간에 아직도 논쟁의 여지가 많다. 피아제의 인지발달론에 의하면, 의식적 조작이 잘 이루어지지 않는 분야가 바로 발 음분야이기 때문에, 따라서 의식적 조작이 이루어지는 '형식적 조작기'이전인 10-11세 정도에서부터 음성언어 중심의 외국어 교육을 실시하는 것이 바람직하다고 본다. 따라서 듣기와 말하기의 기능에 주안점을 둔 초등영어 교육은 감각과 놀이, 게임, 노래나 챈트 둥으로 흥미를 지속시키면서, 영어의 특질인 강세박자리듬언어(stress-timed rhythm language)의 특성올 초창기부터 듣기 및 말하기 훈련으로 지속적으로 연습시킬 필요가 있다고 본다. 또한 James Asher가 창안한 교수법인 천신반용볍(Total Physical Response)도 초기에 말하기에 대한 부담감 없이 흥미 있는 활동을 통하여 학습동기를 높여줄 수 있는 장점을 지니고 었다. 뿐만 아니라, 청취단계에 있어서 초기에는 귀로들은 외국어를 무조건 기억하지 않고 즉각적인 인지로 끌어내어, 점차 이와 같은 인지훈련을 반복함으로써 결국에는 기억에까지 도달하려 하는 초기학습에 중한 역할을 차지하는 학습법이다. 음성학적인 측면에서 초동영어 교육의 시작단계인 3학년에서는 특히 분절음소 차원에서 영어의 자,모음이 우리말의 자,모음과는 다르다는 차이점을 배우게 되고, 초분절 음소 중에서는 강세와 리듬의 차이를 자연스럽게 습득할 수 있도록 정확한 발음을 들려주어 정확한 발음을 해 낼 수 있도록 훈련하는 것이 중요하다고 하겠다. 하지만, 한편으로는 제6차 교육과정의 영어교육 목표가 언어의 '정확성'보다는 '유창성' 에 그 목표를 두고 있는 점을 감안한다면, 시작단계부터 반드시 정확한 발음을 지녀야 하는 가의 문제도 생각해 볼 필요가 있다. 경우에 따라서는, 정확한 발음은 그 언어에 대한 숙련도가 점차 높아짐에 따라 이와 병행하여 이루어지는 경우도 흔히 경험하는 일이기 때문이다. 결국 초등영어 교육과정에도 명시되어 있듯이 '...영어에 대한 친숙함과 자신감을 심어주고, 영어에 대한 흥미와 관심을 지속적으로 유지시키는 것이 중요하기' 때문에 무엇보다 중요한 측면은 흥미와 관심을 유지시키는 지적인 학습활동보다는 정의적인 학습활동의 전개가 필요하다고 하겠다.
