Risk has been considered as one of very important topics in traditional consumer behavior theoretically and practically since its tendency of minimizing errors rather than maximizing utilization in addition to its intuitive appealing with very high explaining power. In addition to a traditional view of risk, importance of risk in online transactions such as Internet banking is due to technical instability in security of the Internet as well as temporal and spatial separation of transaction partners. Therefore, risk in online transactions should be analyzed by a very comprehensive way since it is very inherent in the Internet. The objective of this study is to suggest a research model for explaining the use of online transactions in some risk related variables including risk results, security result, perceived security, and social influence and show its validity by applying it to Internet banking users. In result, hypotheses suggested by our research model are shown to be valid ones.

Despite the development of the aviation industry, aircraft accidents caused by human errors by flight crews continue to occur. In order to reduce such human error accidents, it is important to strengthen flight-related regulations and establish a safety culture in which pilots themselves seek to ensure flight safety, rather than requiring flight crew members to follow them. In this study, the sub-concept of safety culture was classified into three latent variables (safety management, safety atmosphere, and process culture) and eight measured variables to investigate the safety culture awareness of domestic flight crew. The survey results were analyzed by type of airline and flight crew. The purpose of this study is to present a plan to improve the performance of revitalizing the safety culture of domestic flight crew through an empirical comparative analysis according to the number of flight hours and years of service at the airline.

한국어에서는 모음사이에서 겹자음이 나타날 수 있으나 영어에서는 이것이 불가능하므로 영어를 배우는 한국 학생들이 $su\underline{mm}er$와 같이 겹자음 철자를 포함하는 단어들을 발음할 때 철자의 겹자음을 모두 발음하는 오류를 흔히 범한다. 따라서 본 파일럿 연구에서는 한국 학생들이 영어 겹자음 철자를 어떻게 발음하고 인지하는지 살펴보기 위해서 영어 겹자음과 단자음의 (유사) 최소변별쌍으로 구성된 36개의 실제어를 20명의 대학생이 듣고 발음하는 인지와 발화 실험을 실행하였다. 실험 결과 한국 학생들은 철자의 영향으로 영어 단자음 철자 단어를 발음할 때보다 겹자음 철자 단어를 발음할 때 이중으로 길게 발음하는 오류를 더 흔히 범해서 겹자음 철자 단어의 정확율보다 단자음의 정확율이 크게 높았으며, 인지의 경우에도 마찬가지로 단자음 철자 단어의 인지 정확율이 겹자음 철자보다 확연하게 높았다. 덧붙여, 한국 학생들의 영어 유성 파열음의 발화 오류율이 낮은 이유를 한국어 음운 체계의 전이로 설명하였다. 끝으로, 한국학생들의 발화를 스펙트로그램을 통해서 분석함으로써 영어 단자음 철자보다는 겹자음 철자에서 더 많은 발화오류를 일으키는 것도 보여주었고 또한 교육적인 함축점도 제안하였다.

The purpose of this study is to prove the efficacy of the Kaltenborn-Evjenth Orthopedic Manipulative Therapy and the Conventional Physical Therapy that influence changes in pain and range of motion when those therapies are applied to patients with temporomandibular pint movement restriction. The subjects of the study were 30 randomly selected patients who had been diagnosed with temporomandibular pint movement restriction and had endured pain for more than two weeks. These patients had visited one of three hospitals in Pyongchon 00 Hospital. The subjects were divided into two groups with 15 patients each. The Kaltenborn-Evjenth Orthopedic Manipulative Therapy was applied to one group and the Conventional Physical Therapy was applied to the other group, once a day for three days. Then, the pain perception degree was measured by using the Visual Analogue Scale(VAS) and a digital device(Absolute Digimatic) measured the range of motion for each group. The average and standard errors were calculated for each measured items and a paired t-test was used for identifying significance in the differences in the pain perception degree and the range of motion between the two groups according to therapy. The significant level was set as ${\alpha}=0.05$. The changes in the pain perception degree were statistically significant in both groups; however, the group that received Kaltenborn-Evjenth Orthopedic Manipulative Therapy(KE-Group) showed more significant changes in a decrease in the pain perception degree than did the group that received the Conventional Physical Therapy(CPT-Group). Both groups showed significant results regarding changes in the range of motion: however, the KE-Group showed more of a significant difference in the average of the range of motion than did the CPT-Group(p<0.001). Comparing the changes in the range of motion between the two groups, the KE-Group showed a significant result which means that the KE-Group had a higher therapy effect than did the CPT-Group(p<0.05). Based on the results of this study, we found that the Kaltenborn-Evjenth Orthopedic Manipulative Therapy decreased pain and increased the range of motion. With such findings, we expect that the Kartenborn-Evjenth Orthopedic Manipulative Therapy can be used as an effective treatment method for patients with tempomrnandibular pint movement restriction and that the treatment period can be reduced with this therapy as well.

현대에 이르러 첨단 디지털 제작 방식은 우리가 시각 미술에서 추구해 왔던 현실 세계의 재현 문제를 핍진적으로 구현 가능하게 하였다. 그럼에도 불구하고 관객의 시각의 욕구는 사실주의의 시각적 재현에 머무르지 않고 수많은 우연성과 오차를 야기하는 아날로그적 회화성을 요구하고, 그에 부응하여 디지털 제작 방식 또한 사진, 수작업 시각물 등 아날로그 세계의 구현방식을 추구하는 경향을 띠고 있다. 이는 인간의 회귀적 본능에 기인하는 과거 시각적 기억에의 향수만은 아니다. 이는 매체에 대한 관객의 시각적 욕구가 단순히 현실 세계에 근접한 정밀함에 머무르는 것이 아니라 대상에 대한 지각과 인식의 과정을 거치며 새로운 매체에의 믹숙함이 반복되면서 정서적 반향을 일으키는 어떠한 형태의 시각적 자극, 즉 일련의 시지각적 오차에 대한 심리적 요구가 병행된다는 것을 의미한다. 이러한 관객의 욕구와 시각 예술의 구현 방법은 끊임없이 상호 형태를 달리하며 시각적 완성을 추구해 간다.

통계그래픽스는 정량적인 데이터를 이용하여 정보 분석, 추출, 시각화의 과정을 거쳐 정확한 정보전달과 효과적인 이해를 위해 사용자 인지측면에 초점을 둔 디자인 분야이다. 이러한 통제그래픽스에 빅데이터의 구성요소들 내포하게 될 경우 빅데이터 통제그래픽스라고 할 수 있다. 통계그래픽스에서 시각적 요소는 인지부분에 대한 오류를 줄이고 성공적으로 정보를 전달하기 위해 사용되어야 하지만, 빅데이터 통계그래픽스에서는 방대한 데이터로 인해 시각적 요소가 오히려 인지적 방해를 일으키고 있다. 본 연구는 빅데이터 통계 그래픽스에서 나타날 수 있는 인지적 방해요소를 도출하여 제시하는 것을 목적으로 한다. 빅데이터의 통계그래픽스의 유형을 구조적 형태를 바탕으로 '네트워크 유형', '세그먼트 유형', '혼합유형' 세 가지로 분류하였고, 그에 따른 특징들을 탐색하였다. 특히, 빅데이터 통계그래픽스에서 시각적 주요요소를 기반으로 시각화의 고도화 시 나타날 수 있는 인지적 방해요소를 '다차원 범례', '다양한 색채', '정보의 중첩', '서체의 가독성' 네 가지로 도출하여 제시하였다.

본 연구는 시간일지 방식의 생활시간조사와 서베이문항 방식의 노동패널 자료를 대상으로 하여 탐색적 수준에서 측정방식의 차이가 성별 가사노동시간 추정에서 어떤 차이를 낳는지를 비교하였다. 연구결과 우리나라의 경우 서베이문항 방식에서 남성은 자신의 가사노동시간을 과다보고하고 여성은 과소보고하는 경향을 나타냈다. 보고차이에 관한 기존연구에 비추어 볼 때 남성의 과다보고는 일치하지만 여성의 과소보고는 매우 독특하다. 하위집단별 가사노동시간 분포를 살펴보면, 남성의 경우 사별/이혼자 집단에서 과다보고의 경향이 뚜렷이 나타난 반면 여성의 경우 유급노동, 돌봄 및 가사노동 부담이 큰 집단에서 과소보고의 경향이 나타났다. 이러한 보고차이는 가사노동과 관련된 젠더화된 사회규범과 시간부족 인식에 비추어 설명될 수 있었다. 기존연구에서는 과소보고에 대한 이론이 제대로 발달되지 않았는데, 본 연구는 시간부족 인식이 여성의 과소보고를 설명하는 중요한 이론적 가설이 될 수 있음을 제언하였다.

The ability to use information technology has become increasingly important as technological advances continue to sweep through the computing world, and education for improving computational thinking has become globally instituted. In South Korea, informatics subjects have been modified in the 2015 curriculum and are now compulsory in primary and secondary education. However, despite substantial financial investment and numerous studies promoting informatics education, there continues to be a serious lack of pre-service teachers capable of teaching computational thinking. This study investigated pre-service teacher programming education using App Inventor, their perceptions of App Inventor, and how use of the program affected teacher problem-solving abilities and self-efficacy. In the pre-test, the control group and experimental group showed no statistically significant difference; however, the post-test revealed that the two groups showed statistically significant differences in problem-solving skills and self-efficacy. The participants initially showed interest in using App Inventor; however, after practice-teaching and project-based learning, the participants demonstrated a growing negativity toward the program when they made errors and the functional limits of App Inventor became apparent. Although most participants stated that they would not use App Inventor in their classes, the positive statistically significant differences in problem-solving skills and self-efficacy indicate that this study could be utilized as a basis for building a teaching-learning program using App Inventor and creating an educational plan for teaching computational thinking.
