급격한 디지털화로 우리 사회의 변화는 적응과 대처라는 새로운 심리학적 과제를 만들어냈다. 이런 변화의 핵심에는 놀이가 자리한다. 놀이는 전통사회와 산업사회를 거치면서 노동의 부수적인 활동이었으나, 생산성과 효율이 극대화된 디지털 사회에서는 경제, 사회, 문화의 전반을 포괄하는 핵심 활동이 되었다. 그러나 놀이에 대한 이론적 접근은 여전히 산업사회기반의 분석에서 벗어나고 있지 못하였다. 이런 점을 분석하면서 디지털 문화의 핵심적인 특성인 멀티미디어와 소셜 네트워크 및 이들이 결합된 디지털 게임 이용이 이용자에게 미치는 심리학적 영향에 대해 다루었다. 다음으로 기존의 심리학과 디지털 문화 심리학의 차이점을 자아개념, 정보처리방식, 성역할 등을 통해 다루었다. 마지막으로 디지털 문화심리학의 미래 방향, 기존 심리학과의 차별성과 제한점에 대해 논하였다.

One of hypothesis is that sleep loss related to a decrease in serotonergic activity plays a significant role in attempted suicide. A growing evidence suggests that central serotonergic activity plays a key role in the etiology of suicide. It has been reported that the cerebrospinal fluid (CSF) levels of 5-hydroxyindoleacetic acid (5-HIAA), the main metabolite of serotonin, were reduced in suicide attempters. In addition, there is evidence that tryptophan hydroxylase is associated with suicide. The association between sleep and suicide was also suggested by some researchers. Several recent studies have showed the association between sleep disturbance and suicide rates in patients with mental disorders and in a general population. In addition, it has been suggested that serotonin plays a role in maintaining arousal and regulating muscle tone and in regulating some of the phasic events of REM sleep. Especially, it is well-known that 5-HT2 receptors are related to slow wave sleep. In conclusion, it is clear that sleep, serotonin activity, and suicide are linked, although the direction of causation needs clarification. In future, large population-based cohort studies are needed to demonstrate the direction of causation in the relationships between sleep, serotonin activity, and suicide.

The complex roles of flagella in the pathogenesis of Campylobacter jejuni, a major cause of worldwide foodborne diarrheal disease, are important. Compared with the wild-type, an insertional mutation of the flgA gene (cj0769c) demonstrated significant decrease in the biofilm formation of C. jejuni NCTC11168 on major food contact surfaces, such as polystyrene, stainless steel, and borosilicate glass. The flgA mutant was completely devoid of flagella and non-motile whereas the wild-type displayed the full-length flagella and motility. In addition, the biofilm formation of the wild-type was inversely dependent on the viscosity of the media. These results support that flagellar-mediated motility plays a significant role in the biofilm formation of C. jejuni NCTC11168. Moreover, our adhesion assay suggests that it plays an important role during biofilm maturation after initial attachment. Furthermore, C. jejuni NCTC11168 wild-type formed biofilm with a net-like structure of extracellular fiber-like material, but such a structure was significantly reduced in the biofilm of the flgA mutant. It supports that the extracellular fiber-like material may play a significant role in the biofilm formation of C. jejuni. This study demonstrated that flgA is essential for flagellar biosynthesis and motility, and plays a significant role in the biofilm formation of C. jejuni NCTC11168.

The purpose of this study was to discriminate important variables among general self-efficacy, peer attachment, and parent-child communication that could predict internalizing problems(anxiety, depression) of Korean children of divorce. The participants were 101 children aged from 10 to 13. They completed questionnaires and discriminant function analyses were performed. The results showed that (a) the discriminant function derived from 3 variables was effective in classifying high, moderate, and low group of children's anxiety and depression, (b) parent-child communication plays a key role in predicting anxiety and general self-efficacy plays a key role in predicting depression of Korean children of divorce, (c) but peer attachment plays a significant role only to predict depression. This means that anxiety and depression of Korean children of divorce result from different kind of interactions among children's important contexts.

체홉 의 희곡들을 읽을 때 간과 할 수 없는 점이 대사의 중간 중간에 포진 되어 있는 "사이"와 말줄임표의 존재이다. 체홉 의 작품을 연출할 때 수많은 양의 "사이"와 말줄임표 에 어떤 의미를 부연하고 표현해 낼 수 있을까 는 체홉의 작품을 보다 체홉 처럼 보이게 하는 결정적인 요소가 아닐까 생각한다. 배우들은 그들의 연기 속에 "사이"와 말줄임표를 어떻게 녹여내어 표현 할 것인가를 고민해야 한다. 먼저 "사이"와 말줄임표의 적절한 사용은 등장인물의 특징을 확정 짓는데 도움이 될 것이다. 다시 말해서, 개인에 관한 흥미를 집중적으로 표현하는 것이 체홉 극작의 근간을 이루고 있고 적어도 체홉 드라마 속의 침묵은 액션이 상대적으로 부족하다고 여겨지는 체홉의 극을 음악적 역동성을 가진 하나의 전혀 다른 연극텍스트, 즉 정교하게 다루어 져야할 연출적, 연기적 재료로서의 기능을 갖는다 하겠다.

Tales from Shakespeare, written by Charles and Mary Lamb in 1807, is an adaptation of Shakespeare's plays which was intended for children. Shakespeare's poetic language is transmitted into prose, which enables children to easily read his works. Charles and Mary Lamb collaborated in adapting Shakespeare's plays, but they undertook separate duties which revealed different attitudes in their approach to the adaptation. This dissertation examines Mary Lamb's adaption of Shakespeare's problem play All's Well That Ends Well and Charles Lamb's adaption of Shakespeare' tragedy King Lear, with an adapted pattern focusing on the plot and character. Charles Lamb stressed the "imagination of a fairy tale," which was against the trend in children's literature of the time, while Mary Lamb stressed "the moral and didactic element." Mary Lamb was concerned with the education of female children in the early nineteenth-century. As a result, the Tales presents "a double movement" or perspective, which stresses didactic elements, as well as imagination. These ambivalent attitudes caused critical debates in the nineteenth-century. However, the Lambs defended criticism against "the double movement," suspecting themselves to be "no bigger than a child," from the viewpoint of "the imagination," and reading the Tales to be effective at "making a child a virtuous man," from the viewpoint of "an education."

This study typifies fashion mobile plays in a digital environment and explores the experiential value created by them through a case study of a fashion brand mobile app. For the case analysis, mobile plays were divided into four types: intrinsic motivation/active participation, intrinsic motivation/passive participation, external motivation/active participation, and external motivation/passive participation, depending on the mobile players motivation and level of participation. Among the global fashion brand mobile apps released from 2009 to 2019, 16 cases suitable for the analytical framework were used for final analyses. The main results are as follows. First, mobile play value include characteristics such as networkability, immersion, hyper-spatiality, and super-temporality in addition to the attributes of a traditional play such as spontaneity, uncertainty, regularity, and playfulness. Second, the four types of mobile play provide participants with an experiential value such as creative value, emotional value, social value, and exploitative value. This study has academic implications in terms of introducing a new framework that can typify mobile plays and suggest practical implications for what experiential value fashion companies can give consumers through mobile app marketing.

Endoscopic retrograde cholangiopancreatography (ERCP) plays a crucial role in the management of pancreaticobiliary disorders. Although the ERCP technique has been refined over the past five decades, it remains one of the endoscopic procedures with the highest rate of complications. Risk factors for ERCP-related complications are broadly classified into patient-, procedure-, and operator-related risk factors. Although non-modifiable, patient-related risk factors allow for the closer monitoring and instatement of preventive measures. Post-ERCP pancreatitis is the most common complication of ERCP. Risk reduction strategies include intravenous hydration, rectal nonsteroidal anti-inflammatory drugs, and pancreatic stent placement in selected patients. Perforation is associated with significant morbidity and mortality, and prompt recognition and treatment of ERCP-related perforations are key to ensuring good clinical outcomes. Endoscopy plays an expanding role in the treatment of perforations. Specific management strategies depend on the location of the perforation and the patient's clinical status. The risk of post-ERCP bleeding can be attenuated by preprocedural optimization and adoption of intra-procedural techniques. Endoscopic measures are the mainstay of management for post-ERCP bleeding. Escalation to angioembolization or surgery may be required for refractory bleeding. Post-ERCP cholangitis can be reduced with antibiotic prophylaxis in high risk patients. Bile culture-directed therapy plays an important role in antimicrobial treatment.

This study will examine the current condition of outdoor play in child care centers and the overall perception of teachers on outdoor play in regards to its related programs and children's reaction to them. Through examining such issues, this study will provide the basic data that can be applied in planning appropriate outdoor play activities, programs and environments. For the study, we surveyed teachers and directors of child care centers using a structured questionnaire. The objects of the survey were 22 child care centers in Daejeon and Seoul, who agreed to conduct the survey. The survey was conducted from August 1 to September 30 2006; 220 copies were distributed, and 188 copies were collected. The results of the study can be summarized as follows: 1) The number of outdoor plays per week were on average 1~2 in most cases, although teachers believed the play should be done everyday. Outdoor play time was mostly 21~30 minutes, while teachers thought 31~40 minutes as appropriate. Children's reaction scored the highest when they played outdoors for 30 minutes every day with their teachers involved in the play. As a result, we have concluded that the appropriate outdoor play should be conducted everyday for 30~40 minutes. 2) Outdoor play was mostly conducted as part of the overall educational plan rather than a separate plan. Since outdoor play affects children's development as much as indoor play, there is a need for development of a specific and separate plan for various outdoor play programs. 3) The outdoor play program that was most often conducted was equipment play and sand play. This indicated the monolithic nature of the outdoor program. Given the fact that children enjoy outdoor plays a lot (M=4.71), various programs including adventure play, sensitive play, and carpenter play should be developed. 4) In outdoor play, the teacher's role included supervising and interacting with children. According to the survey, teachers had a good understanding of the importance on safety and supervising issues in outdoor plays. However they seemed to overlook the importance of having better programs and improving teacher's participation to the play. Despite the importance of outdoor play to children's development, the result shows that teachers have tendencies to limit and obstruct outdoor plays by emphasizing supervising and safety issues instead. 5) Children's safety should not be the only consideration for outdoor plays; teachers ought to better understand that children's development can be maximized by the play. Furthermore, there should be emphasis placed on the program development and teacher's participation; teacher's participation should actively encourage the interactions between a child and a teacher, as well as among children.
