Alimentary tract duplication cysts are rare congenital anomalies, most commonly located in the ileum, but may present anywhere from mouth to anus.Clinically, they may be asymptomatic, incidentally diagnosed or may present with obstruction, volvulus, intussusception or gastrointestinal bleed. Here we report a case of a one year old male child presenting in gasping state and shock. Despite the initial strong suspicion of Meckel's diverticulum and tubercular abdomen, the final diagnosis remained elusive till exploratory laparotomy was performed which revealed a duplication cyst of ileum with perforation into the umbilicus. Duplication cyst should always be kept as a differential diagnosis so that early intervention can help in better management.

Various dental procedures, such as injection administration, surgical treatment, and endodontic treatment, can cause injury to the nerves. The most commonly injured nerves are the inferior alveolar and lingual nerves. This can manifest as altered sensation to the area of innervation of the injured nerve, such as the lower lip, chin, teeth, tongue, and mucosa. Altered sensations or loss of sensation are relatively infrequent complications in daily dental practice. Here, we report an uncommon case of altered sensation in the midfacial region caused by an endodontic procedure and discuss the need to consider local dental causes in the differential diagnosis of numbness in the facial region.

본 논문에서는 멀티미디어 게임의 흡인요소를 분석하였다. 인지 및 감성을 고려한 흡인요소에는 22가지가 있었다. 이 흡인요소들을 몰입차원과 구현방식 그리고 자극방법 등의 각도에서 그 상관관계를 파악하였다. 그 결과 게임의 흡인요소 22가지 중에서 새로운 게임을 설계할 때 일체감. 자극성, 도박, 현장감, 환상감, 만족감, 성취감 등의 7가지 요소를 우선적으로 고려해야 함을 확인하였다.

유비쿼터스 컴퓨팅환경의 대두로 개인정보 보호에 관한 관심이 더욱 높아졌다 지금의 사람 대 사람에서의 정보보호뿐만 아니라 그 범위는 사람 과 기계, 기계와 기계, 사물과 사물 간으로 넓어지고 있다. 유비쿼터스 환경하에서의 개인정보침해 사례를 살펴보고, 그에 따른 기술적 대응 방안과 법적 대응 방안을 알아본다. 한계를 보일 수 있는 개인정보보호기술은 개인정보보호정책으로 보안하기 위하여 시급한 법제화가 필요하다.

To achieve a sustainable competitive advantage, firm is required innovative activities and competences. However, Small and Medium sized Enterprises (SMEs) is hard to achieve a superior performance because they possess low competences. So, this paper identify determinants of innovation performance by firm size in motor and electronics industry based on a resource-based view. This paper analyzes the effects of innovation activities and competence on innovation performance by using firm-level data provided by Korea Innovation Survey (KIS). The empirical evidence presented shows that there are differences of determinants on innovation performance by industry and firm size.

We analyzed conditions for fabricating zero-bias polymer-stabilized liquid crystal (PSLC) pi cells. A high curing voltage and a very low curing intensity are effective in fabricating the cell with a high bright state, a low dark state and therefore a steep T-V curve. However, the response time of the cell is slow. Finally, a dual-frequency PSLC pi cell with fast response time is developed. The obtained result reveals that the dual-frequency PSLC pi cell has a fast response of under 1ms.

Developmental anomalies of internal carotid artery (ICA), being rare entities, are mostly asymptomatic by themselves because of good collateral supply. However, when present with other associated intracranial anomalies requiring treatment, there can be catastrophic consequences, if special attention is not paid to this condition. We present a case of 36 years old male, who reported to our emergency department with complaints of headache and loss of consciousness. He was diagnosed as a case of ruptured anterior communicating aneurysm with subarachnoid hemorrhage and agenesis of left ICA with trans-cavernous anastomosis. He underwent clipping of aneurysm and was discharged uneventfully. This report highlights the importance of skillful microsurgical clipping in extremely high-risk conditions, in contemporary era of hybrid neurosurgeons.

The purpose of this research is to examine the characteristics of team interaction according to the creativity of team members. Research subjects to achieve this purpose included 28 students who are in engineering education in the College of Education at A University in Daejeon and have taken robot-related courses. Through first and second MBTI, and TTCT tests, the final homogeneous and heterogeneous teams were formed, and an experimental study was conducted by developing team design activity assignment. The major research results were as follows. In terms of a comprehensive view on interaction frequency, both homogeneous team and heterogeneous team suggested had the highest frequency in suggesting opinions. However, each of the team members in the homogeneous team had different communication frequency among each other while each team member in the heterogeneous team had almost similar frequency. A microscopic analysis of the communication process of homogeneous team showed that the team members' roles were divided among each other in communication. Next, according to the microscopic analysis of the heterogeneous team's communication process, the team members exchanged opinions in the beginning, talked to themselves in words that were hard to understand the meanings, and they stopped having conversations in the end. Due to such decrease in communication, two team members could not solve the confusing state of being unable to understand each other's opinions and failed to complete their assignments. The microscopic analysis demonstrated that the homogeneous team had a smooth interaction, because when one team member suggested an opinion during a conversation, other team members agreed with it through a discussion. However, the members in the heterogeneous team experienced confusion as they could not understand each other's conversation and could not overcome this problem, leading to lack of conversations.
