It is required that university students acquire information technology in order to adapt to the information society. Therefore, it is inevitable for universities to provide students with an effective curriculum to improve IT fluency. The purpose of this study is to analyze the content of the informatics learning programs in universities in Korea in terms of IT fluency which is defined by National Academy of Science NRC99. Based on the information that the Academy Information Center announced, the content analysis was carried out from September 2010 to June 2011. According to the result of the analysis, 84 of 201 universities provide the informatics education as a mandatory course. 29 of them mainly provide the programs about word processors, spreadsheet, and presentation that are regarded as contemporary skills. These programs cover the fundamental concept, but the contents which require intellectual capabilities are rarely addressed. Moreover, the informatics education has mainly focused on elementary and secondary education. In this sense, it is valid to analyze the contents and current states of the informatics learning programs required in higher education.

Acute pandysautonomic neuropathy(APN) is an uncommon clinical entitiy involving vasomotor, sudomotor, pupilomotor, secretomotor and other autonomic systems. Both sympathetic or parasympathetic fibers are involved with relative preservation of somatic sensory and motor function. Although APN shares several clinical features with GBS, it is not clear whether APN is a subvariety of GBS. We report two young patients with APN. Patient 1 was a 18-year-old girl with recurrent fainting spells. Patient 2 was a 23-year-old man sufferring from unexplained nausea and vomiting. Both had a history of previous upper respiratory infection. They presented with gastroparesis, anhydrosis and orthostatic hypotension. Mild numbness and tingling sense was present, but motor power was intact. Neurologic examination showed bilateral tonic pupil, decreased pain and vibration sense, and absent tendon reflexes. Nerve conduction study indicated diffuse sensorimotor polyneuropathy. Nerve biopsy in patient 2 revealed axonal degeneration. After conservative management, gastrointestinal symptoms were improved in patient 2, however, patient 1 suffered from the symptoms lasting more than several months. These cases suggest that post-infectious dysautonomic symptoms in young patient may indicate the diagnosis of APN. Although the natural course is generally benign, accurate diagnosis and proper management may be mandatory for the better clinical outcome.

International Maritime Organisation (IMO) regulations insist on reduced emission of CO₂, noxious and other environmentally dangerous gases from ship, which are usually let out while burning fossil fuel for running its propulsive machinery. Contrallability of ship during sailing has a direct implication on its course keeping and changing ability, and tries to have an optimised routing. Bad coursekeeping ability of a ship may lead to frequent use of rudder and resulting changes in the ship's drift angle. Consequently, it increases vessels resistance and also may lead to longer path for its journey due to zigzag movements. These adverse effects on the ship journey obviously lead to the increase in fuel consumption and higher emission. Hence, IMO has made it mandatory to evaluate the manoeuvring qualities of a ship at the designed stage itself. In this paper a numerical horizontal planar motion mechanism is simulated in CFD environment and from the force history, the hydrodynamic derivatives appearing in the manoeuvring equation of motion of a ship are estimated. These derivatives along with propeller thrust and rudder effects are used to simulate different standard manoeuvres of the vessel and check its parameters against the IMO requirements. The present study also simulates these manoeuvres by using numerical free running model for the same ship. The results obtained from both these studies are presented and discussed here.

To evaluate the suitability of UML (Unified Modelling Language) in terms of educating novice software engineers, we have conducted a survey study with 102 students who were enrolled in a mandatory course for sophomores in computer science and engineering department. The results indicate that UML 1) has high satisfaction rate among software novices as an education material, 2) improves computational thinking and problem-solving skills, and 3) increases the efficacy of learning when the education program is implemented in the order of UML, programming practice, and physical computing. This paper suggests the applicability of UML as a new education paradigm in software education.

The purpose of this study is to examine the Marriage Preparation and Preservation Act adopted in Florida which require premarital counseling and covenant marriage laws of Louisiana and Arizona among many kinds of family policy which recently are designed to prevent divorce in the United States of America. Most of states in the U.S. require the marriage license prior to having a marriage ceremony. Covenant marriage legislation has admirable motives to strengthen marriage and cure the defects of the no-fault system. In that legislation, the imposition of waiting period for the no-fault ground of divorce, proof of fault requirements, consent requirements, and mandatory course or counseling attendance will likely serve as deterrents to those seeking divorce as a first resort. To sum up, by offering preventive measures in the form of premarital counseling and waiting period before marriage, covenant marriage will force couples entering marriage to carefully consider their actions before they act and prevent broken marriages in the first place. In response to rising divorce rates, the Koreas family policy has put its emphasis of fixing social problems accompanied with family dissolution. Rather, this study suggests that attention in Korea also should be shifted from broken marriages to preventing them.

The purpose of this study is to investigate the environmental perceptions of pre-service secondary school teachers about the global environment. The Subjects are 133 pre-service secondary school teachers. As an indicator of environmental perceptions, the modified New Environmental Paradigm (NEP) instrument was used. This modified NEP instrument consists of four dimensions: the negative results of growth and technology, relation of humankind and nature, quality of life, and limits of biosphere. The results of this study suggested that a majority of pre-service secondary teachers held ecological environmental perceptions. They also had a similar environmental perception to education major. However, there were significant differences in environmental perceptions and the variables of education experience on environment-related subjects. Based on the findings of this study, it is recommended that environment-related subjects. Based on the findings of this study, it is recommended that environmental education be a mandatory course in education programs.

Objective: This study aims to introduce the bridge resource management (BRM) training courses implemented in Korea and to analyze their effectiveness in several views. Background: BRM training will be a mandatory course for crew members of ships from 2017. At this stage, it is needed to check if the BRM training courses implemented until now was effective to the Korean maritime safety and to investigate if there are more effective training methods. Method: The effectiveness of BRM training intervention in Korea was compared with that of the other countries, using Kirkpatrick's (1976) training evaluation framework. Kim (2012)'s data on the BRM training effectiveness were re-analyzed in order to check if the effects of BRM training are dependent on the bridge work experience. Results: Many BRM training courses has been opened in Korea. However, the methods to assess BRM training effects used in Korea focused on the survey of subjective satisfaction level, not investigating trainees' attitude and behavior change. On the other hand, the effectiveness of BRM training was higher to the bridge officers with long work experience than with shorter work experience. Conclusion: The contents of BRM training should be changed to effectively apply to the context of the real-world exercise and be differentiated depending on the work experience. Research on the methods to measure the BRM training effectiveness is also more required. Application: The results of this study will aid to develop the BRM training courses for bridge officers of ships in the BRM training institutions.

Globally SW education is becoming increasingly important, and the government is preparing for this trend as a mandatory implementation of SW education in the 2015 revised curriculum. However, because the 17 hours of annual education offered in the course of Practical Arts cannot have great educational effects, this study attempted to develop a robot-based SW education program related to other regular subjects. Also in order to verify the effects of the program related to future competencies, problem solving ability and communication ability were selected as key factors. The paired t-test was conducted to examine whether there was a significant difference between pretest and posttest results. As a result, it was verified that the subject-related SW education program using robots was effective in improving students' problem-solving ability and communication ability. In addition, after the program was completed a survey was conducted, and it was possible to confirm that students could have positive perception on SW education.

Recently, there is an increasing number of universities in which SW education is operated as a liberal arts education regardless of major. In this paper, the survey is conducted to analysis the factors affecting the non-majors students' perception of the necessity of SW education through a case study of SW liberal arts by gender, college, and SW learning experience. As a result, men, students of social science college, and students with SW learning experience strongly agreed that SW education for non-majors is essential. 'SW education is very helpful in studying my major' was analyzed as a necessary condition of SW education for non-majors. Especially, the difficulty of SW learning did not affect the recognition of the necessity of non-majors SW education. If the SW liberal education is based on the SW technology that helps their major, it will be expected that the improved learning motivation due to majors-relevance will deepen a consensus on SW education.

Objective : This investigation was conducted to evaluate a new, safe entry point for the C2 pedicle screw, determined using the anatomical landmarks of the C2 lateral mass, the lamina, and the isthmus of the pars interarticularis. Methods : Fifteen patients underwent bilateral C1 lateral mass-C2 pedicle screw fixation, combined with posterior wiring. The C2 pedicle screw was inserted at the entry point determined using the following method : 4 mm lateral to and 4 mm inferior to the transitional point (from the superior end line of the lamina to the isthmus of the pars interarticularis). After a small hole was made with a high-speed drill, the taper was inserted with a 30 degree convergence in the cephalad direction. Other surgical procedures were performed according to Harm's description. Preoperatively, careful evaluation was performed with a cervical X-ray for C1-C2 alignment, magnetic resonance imaging for spinal cord and ligamentous structures, and a contrast-enhanced 3-dimensional computed tomogram (3-D CT) for bony anatomy and the course of the vertebral artery. A 3-D CT was checked postoperatively to evaluate screw placement Results : Bone fusion was achieved in all 15 patients (100%) without screw violation into the spinal canal, vertebral artery injury, or hardware failure. Occipital neuralgia developed in one patient, but this subsided after a C2 ganglion block. Conclusion : C2 transpedicular screw fixation can be easily and safely performed using the entry point of the present study. However, careful preoperative radiographic evaluation, regardless of methods, is mandatory.
