Information skill, which means information technology skill and information handling skill, is related to the aims and processes of higher education as a knowledge creation activity. In this study, a curriculum design is proposed for the development of the information literate student. The framework of this curriculum derives form the US Information literacy standards for higher education 2000, the UK Information skills in higher education 2004, and Australian and New Zealand Information literacy framework 2004. The teaching plan and content is based on the information literacy programs of NMSU, CSU Hayward, and IUE. It is proposed that the development of the idea of information literacy requires a collaborative and integrated approach to curriculum design and delivery based on investigation of user's satisfaction with the curriculum.

As media become diversified, animation fields are being expanded. Various types of animations which were not seen in the past have appeared and the fields which did not have a suffix of "animation" now use the words of animation like motion graphic-animation or interactive-animation. This thesis is a comparative analysis study of U.S. animation education. This study collected and reviewed respective curricula of total 5 universities such as Academy of Art University, California Art of Institute), Ringling College of Art and Design, Rhode Island School of Design, and School of Visual Arts which have led U.S. animation education since animation education was first introduced in 1961. Based on the result drawn from the analysis on the classification of animation curricula into a required subject, an elective subject, liberal arts, a theory subject and a practical subject, it intends to consider improvements of Korean animation curriculum.

The Continuous Risk Profile (CRP) has been well known to be the most accurate and efficient among existing network screening methods. However, the classical CRP uses safety performance functions (SPFs) which require a huge investment to construct a database system. This study aims to suggest a new CRP method using average crash frequencies of homogeneous groups, instead of SPFs, as rescaling factors. Hierarchical clustering analysis is performed to classify freeway segments into homogeneous groups based on the data of AADT and number of lanes. Using the data from I-880 in California, the proposed method is compared to other several network screening methods. The results show that the proposed method decrease false positive rates while it does not produce any false negatives. The method developed in this study can be easily applied to screen freeway networks without any additional complex database systems, and contribute to the improvement of freeway safety management systems.

Purpose The purpose of this study is to find out in extent to which the companies in Korea and oversea, which has been subjected by different laws of their country, have guaranteed the personal information rights and have provided proper 'right to access' to the information subjects. Design/methodology/approach This study compared Korean laws with 'General Data Protection Regulation (GDPR)' of EU and 'California Consumer Privacy Act (CCPA)' to check each of the level of 'right to access' guarantee. In terms of the difference in guaranteeing the right, this study compared Korean IT leading companies with US global leading IT companies to find out how much 'right to access' are properly implemented in their policies and functions they provide. Findings The result of the study shows that 'right to access' has not been well guaranteed by Korean law, as it does not provide the right to choose method and medium by information subjects and does not clarify the types of diverse information. This was clearly opposite with the other laws providing the right to choose what method and medium that subjects want with clarifying every types of personal information possible to be more. In addition, 'right to access' has not been well guaranteed by Korean companies in comparison with by the oversea companies which proactively guarantee the right by setting the function enabling subjects to browse their information through their websites or applications.

Agricultural drainage salt generated during irrigation of crops in San Joaquin Valley, California, exceeds 600,000 tons annually and cumulates in the field in a rapid rate. As a result, the waste is taking out more farmlands for salt storage and disposal, imposing serious concerns to environment and local agricultural industry. In searching for a potential solution to reduce or eliminate the waste, this research explored feasibility of producing a value-added product, sodium sulfate, from the waste and utilizing the product in textile dyeing. The results indicated that sodium sulfate could be produced from the salt and could be purified by a recrystalization method in a temperature range within the highest and lowest daily temperatures in summer in the valley. The recovered sodium sulfate samples, with purities ranging from 67% to 99.91, were compared with commercially available sodium sulfate in the dyeing of levelling dyes with nylon/wool fabrics. In nylon/wool fabrics, C.I. Acid Yellow 23 had similar exhaustions among Na₂SO₄ I, Na₂SO₄ II, Na₂SO₄ III and Na₂SO₄ Ⅴ which had similar ratios of sodium sulfate and sodium chloride in recovered salts. Na₂SO₄ Ⅳ had low exhaustion which had low ratios of sodium sulfate and sodium chloride. In nylon/wool fabrics, C.I. Acid Blue 158 had similar exhaustions among Na₂SO₄ I, Na₂SO₄ II, Na2₂SO₄ III, Na₂SO₄ IV and Na₂SO₄ Ⅴ despite of Na₂SO₄ Ⅳ had low ratios of sodium sulfate and sodium chloride Generally, the dyeing of levelling dyes using recovered salts from farm drainage has similar or low exhaustion than the dyeing of levelling dyes using commercial sodium sulfate.

This research focuses on the issue of seismic retrofit prioritization based on the Caltrans' highway network serving Los Angeles and Orange counties. Retrofit prioritization is one of most important problems in earthquake engineering, and it is a problem that most decision makers face in the process of resource allocation. This study demonstrates the methods of prioritized resource allocation in the process of retrofitting a regional highway network. For the criteria of a retrofit ranking, seismic vulnerability and the importance of network link are first introduced. Subsequently, link-based seismic retrofit cases are simulated, investigating the effects of the seismic retrofit in terms of seismic performance, such as driver's delay. In this study, probabilistic scenario earthquakes are used to perform a probabilistic seismic risk analysis. The results show that the retrofit prioritization can be differently defined and ranked depending on the stakeholders. This study provides general guidelines for prioritization strategy for the effective retrofitting of a highway network system.

In this knowledge information society, it cannot be too much to accentuate the necessity and importance of computer education. However, the current computer education in elementary school only focuses on computer application and utilization. It is not satisfactory to the needs of knowledge information society to improve mechanic office operation and/or to provide simple utilization of educational software through learning the application software functions. Therefore, based on creative and logical thought, it is necessary at this era to prepare computer education as the essence of science to create new values and to embody knowledge by understanding social and cultural environment of knowledge information society that is continuously in change and development. Accordingly, this study presents the necessity of change based on problems of computer education, and investigates field teacher's opinion on the direction of change in elementary computer curriculum in this knowledge information society. Also, this study presents a computer education curriculum for elementary school students by focusing on a comparison between our current elementary computer curriculum and that of North Carolina and of California in the United States.

Objectives: Although Asian immigrants have lower rates of smoking and binge drinking than other ethnics in the US, Korean Americans have the highest rate of Asian immigrants. This study, therefore, compared with the rates and examined the predictors of smoking and binge drinking by gender and ethnicity among Asian immigrants in California. Methods: In 2001 and 2003, California Health Interview Survey (CHIS) were conducted in English and their original languages with Asian immigrants residing in 58 Counties and 3 Cities, California. We performed analysis to find out the differences of smoking and binge drinking rates using the secondary data, CHIS 2001 and 2003. Multiple logistic regression analysis for survey data identified predictors of smoking and binge drinking behaviors by gender and ethnicity. Results: Korean American males (35.4%) and Japanese American females (15.4%) had higher rates of smoking prevalence compared with other Asian immigrants in California. In binge drinking, 26.5% of male and 8.1% of female among Korean Americans were binge drinker, and the rates were the top with Asian Americans who had lived in California. It showed the remarkable gap between gender of smoking and binge drinking among Vietnamese immigrants, whereas not the striking difference among Japanese Americans. In multiple regression models, age, educational level, occupation, marital status, English proficiency, and health insurance coverage remained significant for smoking and binge drinking behaviors(P<0.05). Even though the time in the US was not significant, it seemed to be related to educational level and English proficiency. In particular among female, smoking and binge drinking behaviors were associated with acculturation. Conclusion: Although Asian Americans had shared with American culture since they had immigrated in the US, they had significantly different prevalence rates of smoking and binge drinking based on gender and ethnicity. Therefore, future efforts should be focused on understanding differences by ethnicity and target at high-risk subgroups. To achieve this, it needs to develop the educational materials in Korean and their original languages.

광결정(photonic crystal)으로 광원의 자발 방출을 조절하면 문턱전류 없는 레이저, 고효율 다이오드, 파장 크기에서 손실 없이 급격히 꺾을 수 있는 광도파로 등 기존의 광소자에서 얻을 수 없는 좋은 성능을 얻을 수 있을 것으로 예상된다. 이러한 광결정은 유전체를 파장정도 크기에서 주기적으로 배치시킨 인공적인 결정인데 고체에서 원자의 주기적인 배치로 전자가 전파할 수 없는 진동수 영역, 즉 밴드갭이 생기는 것과 유사하게 빛에 대해서 빛이 전파할 수 없는 진동수 영역인 광밴드갭(photonic bandgap)을 가진다. 그런데 관심있는 광영역에서 3차원 모든 방향으로 광밴드갭이 있는 구조물은 마이크로미터보다 작은 내부 구조를 가지는 복잡한 3차원 구조물로 제작이 어렵다. 이러한 어려움을 극복하기 위해 제작이 비교적 용이한 3차원 광밴드갭 구조물이 찾아지고 있다. 다른 접근 방법으로 평면(x-y)에서는 2차원 광밴드갭을 이용하고 제 3의 방향(z축)으로는 전반사를 이용하는 구조는 제작이 용이할 뿐만 아니라 처음부터 광원의 편광을 TE 또는 TM 모드로만 방출 되도록 준비해 줄 수 있으면 거의 3차원 광결정에서 얻을 수 있는 효과를 낼 수 있는 것으로 발표되었다.$^{(1)}$ 이 방법을 이용하여 최근에 미국의 캘리포니아 공과대학(Caltech)을 중심으로 레이저 동작을 보여 주었다.$^{(2.3)}$ 공기로 둘러싸인 얇은 유전체 평판에서 생기는 전반사와 평판 위에 2차원 삼각형살창(triangular lattice)에 구멍을 뚫어 얻는 2차원 광밴드갭을 이용해 3차원 공진모드를 형성하였다. 이러한 구조에서 1개만 구멍을 매워서 만든 공진기는 저온(143 K)에서 레이저 발진을 보였고 여러 개의 구멍을 매운 경우는 상온에서 펌프 펄스의 유지시간이 0.5% 인 경우 레이저가 동작하는 것을 보여주었다. 이는 구조내에서 열전도가 문제가 된다는 것을 의미하는데 위아래가 공기로 둘러 싸여 있어 발생한 열이 가는 유전체 네트웍을 통해서만 전달 될 수 있기 때문이다.

This paper presents a new approach for determining an accurate incentive levels of Direct Load Control (DLC) program using probabilistic techniques. The economic analysis of DLC resources needs to identify the hourly-by-hourly expected energy-not-served resulting from the random outage characteristics of generators as well as to reflect the availability and duration of DLC resources, which results the computational explosion. Therefore, the conventional methods are based on the scenario approaches to reduce the computation time as well as to avoid the complexity of economic studies. In this paper, we have developed a new technique based on the sequential Monte Carlo simulation to evaluate the required expected load control amount in each hour and to decide the incentive level satisfying the economic constraints. In addition, we have applied the variance reduction technique to enhance the efficiency of the simulation. To show the efficiency and effectiveness of the suggested method, the numerical studies have been performed for the modified IEEE 24-bus reliability test system.
