The purpose of this study is to evaluate an effect that presbyopia correction with PAL(Progressive Addition Lens) influences upon the vision related quality of life. 70 presbyopes over 45 years old in the capital region put a new PAL spectacles for more than 1 month. NEI VFQ questionnaire was used to compare the quality of life after using PAL spectacles and to analyze how much the quality of life has been improved. Myopia and non-myopia groups were not differed, however two groups were significantly improved. There were no differences between low addition group and high addition group, however after the experiment the quality of life in low addition group was improved in more many areas than one of high addition group. Low amount of astigmatism group and high amount of astigmatism group also had no differences, however two groups were also improved significantly after the experiment. Indirect astigmatism, direct astigmatism and oblique astigmatism groups have no differences, however oblique astigmatism group has no a significant difference, and the quality of life in indirect astigmatism group was improved in various items more than direct astigmatism group after the experiment. Comparisons among habitual types of presbyopia correction showed no a significant difference, however the single vision group was improved by much in the quality of life among 4 groups. As the result, Presbyopia correction using PAL were improved the quality of life significantly in their mental, social, visual and functional areas.

The incidence of oral cancer varies widely worldwide. Its treatment often produces significant functiona l and cosmetic morbidity and its mortality continues to be high. Strategies for diagnosing, managing and preventing the disease must be based on an understanding of r isk factors and the pathogenesis of the disease locally. The World Health Organizat ion has documented that few countries have a comprehensive a pproach to the diagnosis , management and prevention of cancer at various anatomic sites. This presentation will review the United States’ experience with oral cancer and its strategies fo1' affecting incidence and prognosis . The greatest obs tacles are often political and economic, not scientific.

본 연구에서는 얼굴표정을 통하여 다른 사람의 정서 상태를 판단하는 능력이 연령(3세, 5세, 대학생), 성별(남, 여), 얼굴제시영역(얼굴전체, 눈), 정서의 종류(기본정서, 복합정서)에 따라 어떻게 다른지 알아보고자 하였다. 본 연구에서는 얼굴표정과 정서어휘 간의 연결이 비교적 분명하게 나타나는 32개의 정서 상태를 자극으로 사용하였으며, 표정사진은 32개의 정서 상태에 해당하는 얼굴표정을 배우에게 연기하도록 하여 사용하였다. 과제는 각 실험참가자에게 정서유발 상황에 대한 이야기를 들려주고 이야기 속의 주인공이 어떤 얼굴표정을 할 것인지를 판단하게 한 후 네 개의 얼굴표정 중에 적절한 것을 선택하도록 한 것이었다. 그 결과 연령이 증가함에 따라 얼굴표정을 판단하는 능력이 증가하였으며, 눈만 제시한 경우보다는 얼굴전체를 제시하였을 때, 복합정서보다는 기본정서에서 더 좋은 수행을 보였다. 또한 여자는 제시영역에 따른 수행의 차이가 없는 것에 반해, 남자는 눈 조건에 비해 얼굴조건의 경우에 더 좋은 수행을 보였다. 본 연구의 결과는 연령, 얼굴제시영역, 정서의 종류가 얼굴표정을 통해 타인의 정서를 판단하는데 영향을 줌을 시사한다.

최근 들어 인간과 컴퓨터 상호작용 분야에서 기존의 인지적인 측면 이외에 감정의 역할에 대한 관심이 증폭되고 있는 추세이다. 본 연구에서는 사용자가 좁은 화면을 통해 의사 결정을 위한 정보검색을 수행 할 때 감정 상태에 따라 정보 검색 패턴이 달라지는지를 알아보고자 하였다. 본 실험에서 실험참가자들의 감정 상태를 긍정적 혹은 부정적 상태로 유도하기 위해 긍정적인 감정과 부정적인 감정을 유발시킬 수 있는 음악을 듣게 하였고 동시에 자신의 과거 기억으로부터 긍정적인 감정 혹은 부정적인 감정을 유발시킬 수 있는 자서전적 회상 과제를 수행하도록 하였다. 감정 유발 과정이 끝난 뒤 각 실험 참가자들은 작은 디스플레이를 통해 세 나라들에 대한 여행 정보를 검색하여 가장 선호하는 여행지를 선택하였고, 실험참가자들이 탐색한 링크들의 경로 및 각 링크에 머무른 시간 등이 실시간으로 기록되었다 실험결과 긍정적인 감정 상태에서는 중립 상태와 부정적인 감정 상태에 비해 보다 신속한 정보탐색이 이루어지는 것으로 나타났고, 중립 상태와 부정 감정 상태에서는 긍정 감정 상태에 비해 세부 항목에 상대적으로 많은 양의 인지적 자원을 할당하는 것으로 나타났다.

The deformation under radial pressure of rectangular dies for metal powder compaction has been investigated by FEM. The explored variables have been: aspect ratio of die profile, ratio between diagonal of the profile and die height, insert and ring thickness, radius at die corners, interference, different insert materials, i. e. conventional HSS, HSS from powders, cemented carbide (10% Co). The analyses have ascertained the unwanted appearance of tensile normal stress on brittle materials, also "at rest", and even some dramatic changes of stress patterns as the die height increases with respect to the rectangular profile dimensions. Different materials behave differently, mainly due to difference of thermal expansion coefficients. Profile changes occur when the dies are heated up to the temperature required for warm compaction. The deformation patterns depend on compaction temperature and thermal expansion coefficients.

마약류나 유해화학 물질의 남용에 의한 중독은 사용물질의 종류에 상관없이 질병으로 간주되어야 하고 약물남용자의 치료와 재활은 하나의 일관된 개념에 의해 통합적으로 다루어져야 할 필요가 있다. 그러나 현재 우리나라 약물남용자의 처벌과 치료․재활은 각기 다른 법률에서 다루어지고 있으며 그 처우의 정도가 서로 다르게 규정되어 있고 누락되어 있는 경우도 있다. 또한 치료보호규정이 있는 경우에도 치료와 보호는 형식적으로 운용되고 있어서 중독에 대한 진정한 치료가 불가능하고 재범과 재발을 반복하고 있는 실정이다. 이에 본 연구에서는 미국의 약물법정제도를 분석하여 우리나라의 약물법정제도 운영에 관한 도입 방안을 제시하였다. 특히 본 연구에서는 구체적인 서비스 흐름을 보다 명확하게 하기 위하여 서비스의 전문성, 적절성, 포괄성, 그리고 통합성 등의 서비스 전달체계 중심으로 분석하였다.

염산매질에서 산화/환원제를 사용하여 Pu 산화수를 조절한 후, UV-Visible-Near IR 분광기를 이용하여 Pu(III, IV, V, VI) 산화수에 대한 흡수스펙트럼을 측정하여 그 분광학적 특성을 고찰하였다. Pu(III)으로 조절하기 위하여 환원제인 HCl를 사용하였으며, Pu(IV)와 Pu(VI)로 조절하기 위하여 산화제인 및 를 각각 사용하였다. 또한 Pu(VI)로 조절된 용액에 환원제인 HCl를 사용하여 Pu(V)로 조절하였다. Pu(III)와 Pu(IV)의 대표적인 흡수피크는 470 nm 및 600 nm에서 각각 관찰되었고, Pu(VI)와 Pu(V)의 특성피크는 830 nm 및 1135nm에서 각각 관찰되었다.

The purpose of this paper is to show that South Korean students of Japanese have a gap between their knowledge and usage of Japanese honorifics, and to illustrate misusage of Japanese honorifics by the South Korean students through the analysis of the example sentence, “My father went to the United States.” According to analysis of this paper, native Japanese speakers are influenced by both the UCHI-SOTO relation and the vertical relation of age when they refer to their father. But the students are influenced only by whether “father” is their father or other’s father. Furthermore, the students don’t necessarily recognize the rule in Japanese honorifics, that is, “Do not use the honorifics when you speak of your father to a person outside the family (SOTO).” The conclusion of this paper gives the following suggestive points to the teaching of Japanese honorifics. First, we have to teach that how to refer to “father” varies with the listener. Second, it is required to fully explain the concept of UCHI-SOTO and to make well-known the rule in Japanese honorifics, that is, “Do not use the honorifics when you speak of a person in your group to a person outside your group.”

In the United States, the implementation of educational technology is influenced by many factors, but in elementary-secondary and higher education the recent economic recession forced a slowdown in investments.. In higher education, analog media, such as overhead projection, videos, and slides, are still heavily used. Digital media use is growing, but at a slower rate each year. Most instructors exchange e-mail with students, but smaller percentages use more sophisticated applications. Course management systems, now ubiquitous, are prompting the integration of technology into instruction. Over two-thirds of all universities offer distance education, and enrollments grow by about 25 percent per year. In elementary-secondary education, technology integration has been influenced by the “No Child Left Behind” initiative. Hence, the focus has been on the use of computers as a tool for assessment. When at school, students in grades 4-12 use computers predominately in a computer lab, most commonly to find information, visit school websites, and to take tests. K-3 students use technology to play learning games, create pictures, and practice spelling and reading. The student-per-Internet– connected computer ratio was 4.3:1 in 2004. Schools are going wireless fast. Professional development continues to lag behind teachers’ needs. The largest barriers to greater adoption and use of computers are lack of time to prepare and insufficient technical support. Virtual schools continue to proliferate and attract new students. These findings indicate that pervasive access to information technology infrastructure does not guarantee its use. Social and psychological factors impinge on educators’ use of ICT.

In this study, we designed color of tunable and high efficient organic materials using the quantum dynamics and the semi-empirical calculation, and applied this results to the fabrication of organic light-emitting diodes. Also we optimized the molecular structure of phosphorescent materials and the energy transfer from a host to a dye which makes organic light-emitting diodes improve. Using quantum dynamics method, the molecular structures of ligand only and the whole metal chelate were optimized, and these energy levels were calculated. From this test results, we could understand the emission mechanism of phosphors with various ligands as well as design the proper ligands reducing the T-T annihilation and the carrier lifetime. We also could design ligands with various colors using this test method.

This study identifies and compares science content standards that are approved by departments of education in six states: California, Connecticut, Michigan, New Jersey, Texas, and Virginia. Specifically, the study examines the goals/visions, the organizing/progression principles, the strands of science content, and earth science content found in the states curriculum standards compared to National Science Education Standards. Although many states followed the recommendations of NSES or Project 2061, the format and content of the state science standards reviewed are very diverse. The diversity seems to reflect the diverse perspectives and needs of the states. The results of this study provide Korean educators and teachers with useful models or examples to incorporate Korean national science curriculum guides into the science curriculum frameworks of their regions or schools.

The purposes of this study are to suggest issues to provide more effective vocational training of inmates by investigation differences in training system between Korea and United States. Current training systems are analysed from the viewpoints of operating body, curriculum and performance measurement. The Bureau of Prisons(BOP) in both counties has long recognized the importance of vocational training as an opportunity for inmates to improve their knowledge and skills and to support successful integration into the society. While American BOP establishes open network with other administrative bodies and professional institutes to ensure quality of training, Korea BOP carries out training independently. In addition, in many cases, American institute starts with needs assessment to provide more suitable training based on the level of inmates and try to measure performance results. According to the Federal Bureau of Justice, There is an inverse relationship between recidivism rates and vocational training. The more training received, the less likely an individual is to be re-arrested or re-imprisoned. To improve quality of vocational training of inmates, Korean BOP needs to cooperate with other government bodies and to establish open training network by including professional institutes. In addition, the benefits of vocational training should be measured and publicized to ensure quality of training and to secure funds for inmate vocational program. Furthermore, various job placement programs should be accompanied to provide smooth transition to the society.
