  • Many former researchers demonstrated that algorithm learning has a positive outcome on students' problem-solving abilities. One of the methods for algorithm learning, the 'programming learning' method is highly effective. However, there are numerous constraints in schools for programming learning. This study attempts to overcome these issues. Squeak Etoys, one of the educational visual programming languages for easy and interesting learning, has been selected as a learning tool. We developed the algorithm-learning curriculum for middle school students. They were divided into a control group and an experimental group. The students learned on the basis of equal curriculum but, they used other learning tools through over a total 6 sessions. The result showed that Squeak Etoys based Algorithm learning has a positive effect on improving middle school learners' problem solving abilities, self-efficacies and logical thinking abilities. Although the students' logical thinking abilities in the experimental group are improved a lot more than the students' abilities in control group, the students' logical think abilities in the both groups are improved. Therefore, algorithm education in secondary schools are necessary. In conclusion, Squeak Etoys based Algorithm learning has a positive effect on problem solving ability and self efficacy. The developed curriculum can be applicable as a basis for study on algorithm learning and educational programming language.

  • This study inquired following research questions by a narrative research method : What was the job of an engineer in mechanical design field? How did he fulfill his job-related learning in his workplace? What were the context and the characteristic of the job-related learning in the workplace? And some implications of the job-related learning on engineering education were discussed. We identified that the research participant's career as a mechanical engineer has developed through three stages. At first, he engaged on conceptual design of a semi-conductor test machine through self-initiated learning from basic to whole system of the machine. At second stage, he leaded a design group for the concrete design of a ball type semi-conductor test machine. In this stage he learned the meaning of cooperation and cooperative learning. At third stage, he initiated to found an entrepreneur company that was specified to design a semi-conductor test machine. He became CEO of the company. He learned the R & D policy making through contacts with global company, visiting exhibition in abroad. Eventually his main task as a mechanical engineer was the problem solving in the process of machine design. He had experienced and learned through his works : project management, independent fulfilling of tasks, functional analysis and reverse engineering, conceptualizing and test, cohesive cooperation, dialogue and discussion, mediation of conflict, human relationship, leadership. The implication of the narrative analysis on engineering education is, proposed, to give the students more chances to experience and to learn such activities.

  • Kon Satoshi is a representative animation film director who explores human's intrinsic self-identity based on ambivalence and delivers a message for self-reflection of entity. The aim of this study is to analyze the persona of character according to the way how a self incorporates with another self in his film; that is to say, how a mask of the personality expresses and realizes itself from the perspectives of the Jung's analytical psychology. The persona, defined as the upmost external personality, involves social behavior playing a specific role to establish constant relationship with others in a society. With increasing demand in a society, individuals get to adapt to outer environment by playing his/her given role in various masks of personality. In this way, although persona acts as a major function in relationship with outer world, it would exert a negative influence on formation of self-identity because of the inconsistency between consciousness and unconsciousness when immersed only in mask of personality, complying excessively with the demand of group. However, persona does not always have a negative effect on relationships. Developed adequately to fulfill its social function, persona is helpful to establish a healthy self-identity with balanced control between inner world of unconsciousness and outer world of consciousness. From these perspectives, this study can identify how the desire of mask hidden inside of each character expresses to function in a positive or negative way by analyzing characters in the film according to integrated pattern and correlation between consciousness and unconsciousness. Additionally, I hope that the psychological research methods in this study will be full of help for interpreting on a character analysis as a theoretical approach.

  • This study investigated the factors affecting the satisfaction and the continuous behavior intention of university students on MOOC. Adopting a questionnaire, the study collected data from 177 students enrolled in K-MOOC classes as an extracurriculum in the university in metropolitan area. Results indicated the following. First, the university students' satisfaction and continuous use intention on K-MOOC are higher during the semester than in vacation. Second, the perceived ease of use, usefulness, and task-technology fit influence the users'satisfaction on K-MOOC. Meanwhile, the perceived ease of use, task-technology, and user satisfaction likewise influence the users'continuous behavior intention. Hence, the study proposes that the subject matter on K-MOOC and the amount of educational content be made diversified, and the period of K-MOOC be made similar with that of the regular semester. The platform should also be stabilized, and the adequacy in mobile environment be improved. To further activate K-MOOC utilization in the university, the depth of contents and interaction between professors and students also need to be considered.

  • Pain has at least two dimensions such as somatosensory qualities and affect and patients are frequently asked to score the intensity of their pain on a numerical pain rating scale. However, the use of a undimensional scale is questionable in view of the belief, overwhelmingly supported by clinical experience as well as by empirical evidence from multidimensional scaling and other sources, that pain has multidimensions such as sensory-discrimitive, motivational-affective and cognitive-evaluative The study of pain has recently received much attention, especially in understanding its neurophysiology by using new brain imaging techniques, such as positron emission tomography(PET) and functional magnetic resonance imaging (fMRI), both of which allow us to visualize brain function in vivo. Also the new brainimaging devices allow us to evaluate the patients pain status and plan To treat patients objectively. Base4 on our findings we presented what are the new brain imaging devices and the results of study by using brain imaging devices.

  • In this study, we analyzed the teaching practices of science teachers using smart technologies and investigated their difficulties in implementing smart education and their educational needs. We also studied their opinions on the application of smart technologies in science education. The participants were seven science teachers who participated in the smart education study group of a science teacher association in Seoul. We elaborated on the characteristics of smart education in science education during comprehensive analyses of instructional materials used in science classes and the initial interviews. We then analyzed the second interviews by categorizing their responses inductively. All the science teachers used the 'instant access as needed', but their interactions, simply answering students' questions, were found to be at a low level. They did not effectively use the 'collaborative interaction with SNS or wiki-based service' for the support for interactive learning. While most collected learning results of their students and provided feedback in the aspect of 'individualization according to leaner level', they were not aware of 'context, situation, and location of learners' in smart education. While all the teachers extended learning opportunities by using learning resources widely in smart education, most were not aware of 'support for self-directed learning'. Most teachers believed that smart education should be developed to help students learn interactively and in a self-directed manner. They also provided many opinions on teacher training programs and environmental support for smart education. Based on the results, some considerations for implementing smart education in science instructions effectively are discussed.

  • This study examines why follow-up investigative programs about the sinking of the Cheonan Patrol Combat Corvette(ROKS Cheonan) have not been produced, despite much speculation surrounding the cause of the sinking since November 2010, when KBS investigative program, In-Depth 60 Minutes which had covered the incident was aired. We have uncovered four reasons through a series of in-depth interviews with producers and reporters, as follows. First, Korean military authorities monopolized relevant information, while the producers could not prove or confirm the validity of the findings of the JIG(Joint Civilian-Military Investigation Group)'s report because the facts had been revealed partially and selectively by the authorities and the press' scientific investigation were rejected by the authorities. Second, the crew of In-Depth 60 Minutes was subjected to severe disciplinary action by the Korea Communications Commission. This caused a chilling effect, - it broke the producers' resolve to further explore the reason behind the sinking. Furthermore, the screening of the investigative documentary, Project Cheonan Ship was cancelled without prior notice, presumably by the power of the State and markets. Third, the reorganization and shake-up of personnel by broadcasting stations' presidents appointed by the power of the State crushed the spirit of PD Journalism. Finally, the "red purge" factions stigmatized by the political or military, or the mainstream press, caused the producers or broadcasters to engage in self-censorship. The idea has been used in Korea as a smoke screen to deflect public attention. Nevertheless, the producers hope to shed light on the Cheonan sinking incident and to prove reasonable doubts by pursuing follow-up investigations.

  • The modern state has always followed a variety of risks in the industrialization and informatization trends in the development of science and technology. Under such an environment, A matter of State compensation should take into consideration a variety of values such as harmony relief victims' rights in accordance with the principles of the rule of law, suppression of illegal acts of public servants, ensuring stable performance of official duties, the national treasury stability. As the state takes responsibility for an act of a public servant in a modern constitutional state, there may be a doubt on that the state takes responsibility only when there is a deliberation or a mistake. According to the theory of the self-responsibility, which suits the Constitution, the principle of liability with mistake on the State Compensation Law shall be excluded. I agree to the opinion that a subjective responsibility prerequisite such as a deliberation or a mistake is not required in relation to the liability of reparation on the State Compensation Law. Therefore, it is needed to convert the principle of state liability of reparation from the principle of liability with mistake to the principle of liability without mistake through a fundamental revision of the State Compensation Law.

  • 초고속 증착은 짧은 시간에 박막 형성을 가능하게 하므로 window glass 코팅등의 대면적 코팅에 있어서 비용을 절감 시키고, 대량생산을 가능하게 만들기 때문에 관심이 집중되고 있다. 고속증착 공정으로는 high current arc, laser arc, hollow cathode discharge ion plating 그리고 마그네트론 스퍼터링법 등이 있다. 특별히 마그네트론 스퍼터링법은 3m이상의 넓이에 코팅을 할때 두께가 매우 균일하며, 증착율은 evaporation 공정에 비해 경제적, 기능적인 면에서 효율적이다. 그리고 증착된 박막은 매우 조밀하고 좋은 밀착력을 갖고 있으며, 고융점 금속을 포함하여 금속 합금 및 혼합물의 비율을 조정 및 금속 산화물, 질화물, 탄화물 등과 같은 금속의 증착도 stoichiometry를 조정하여 박막을 합성 시키는데 있어서 효과적이다. 이러한 초고속 증착을 만들기 위한 마그네트론 스퍼터링법의 요건은 마그네트론 원이 높은 타켓 power density를 가져야 하며, 타켓에서 효율적으로 플라즈마를 구속하여 스퍼터 되는 이온의 양을 최대화 시킬 수 있어 한다. 따라서 본 실험에서는 초고속 증착을 위해서 직경 50mm 타켓의 UBM magnetron원을 설계 제작하였다. 고밀도의 플라즈마를 형성시키기 위해서, Poisson simulation c code를 이용하여 자기장의 방향, 세기 및 밀도를 측정 하였고, 자기장 측정기(Gauss meter)를 이용하여 실제 자장을 측정 비교 분석하였다. 상기의 data를 바탕으로 여러 형상의 마그네트론원을 설계, 제작하였고. 마그네트론 원의 특성 분석을 위해 I-V 방전 특성을 평가하였고 substrate ion current density와 박막의 증착율을 측정하였다.duty-on 시간의 증가에 따라 $Cr_2N$ 상의 형성이 점점 많아져 80% duty-on 시간 경우에는 거의 CrN과 $Cr_2N$ 상이 공존하는 것으로 나타났다. 또한 duty-on 시간이 증가할수록 회절피크의 세기가 증가하여 결정화가 더 많이 진행되어짐을 알 수 있었다. 마찬가지로 바이어스 펄스이 주파수에 다른 결정성의 변화도 펄스의 주파수가 증가할수록 박막이 결정성이 좋아지고 $Cr_2N$ 상이 쉽게 형성되었다. 증착 진공도에 따른 결정성은 상대적으로 질소의 농도가 높은 낮은 진공도에서는 CrN 상이 주로 형성되었으며, 반대로 높은 진공도에서는 $Cr_2N$ 상이 많이 만들어졌다. 즉 $1.3{\times}10^{-2}Torr$의 증착 진공도에서는 CrN 상만이 보이는 반면 $9.0{\tiems}1-^{-2}Torr$ 진공도에서부터 $Cr_2N$ 상이 형성되기 시작하여 $5.0{\tiems}10^{-2}Torr$ 진공도에서는 두개의 상이 혼재되어 있음을 알 수 있었다. 박막의 내마모성을 조사한 결과 CrN 박막의 마찰 계수는 초기에 급격하게 증가한 후 0.5에서 0.6 사이의 값으로 큰 변화를 보이지 않았으며, $Cr_2N$ 박막도 비슷한 거동을 보였다.차 이, 목적의 차이, 그리고 환경의 의미의 차이에 따라 경관의 미학적 평가가 달라진 것으로 나타났다.corner$적 의도에 의한 경관구성의 일면을 확인할수 있지만 엄밀히 생각하여 보면 이러한 예의 경우도 최락의 총체적인 외형은 마찬가지로 $\ulcorner$순응$\lrcorner$
