In spite that spatial ability has been recognized as an important element of academic achievement in engineering studies, researches on the topic are rather limited in Korea. In this study, the relationship between spatial visualization skill and academic achievement of engineering students was investigated based on the several variables such as gender, high school education background and college course achievement. The result showed that there were significant relevance between spatial visualization skill and gender, high school type, achievement of high school level math & physics, and college course work grade of computer graphic and capstone design. According the case study, from the entry time of engineering college, support programs to reinforce spatial visualization skill are required for lower skill groups such as female and graduate from art course in high school. Also, college curriculum such as Engineering graphics, Capstone design are substantial to improve spatial visualization skill. However, more diversified sample groups and research methods are required in order to draw in depth results.

The major limitation of the traditional Intelligent Tutoring Systems (ITS) is that interface is mainly focused on the cognitive factors. However, the new direction of ITS is shifting form the cognitive perspectives to the motivational perspectives reflecting the individual differences. In this study, the specific design guidelines for motivational interface of ITS are proposed to promote learner's motivation to learn during the interaction with the ITS. First, ITS should be able to reflect individual differences in cognitive abilities, interest and motivation, and ongoing changes of the interestingness and comprehensibility during learning activities. Second, it is essential for ITS to guarantee learner controllability, diverse learning activities, curiosity, self-relevance, and challenge to enhance the level of motivation and situational interest. Third, the game-like properties are also needed to maximize the motivational effect of learning with ITS.

The current study reported on the continuing relevance of the schema theory for reading as it relates to the field of teaching and SLA, whilst highlighting the inherent limitations affecting individual learners. A relevant study was conducted for this article focusing on the extent to which university teacher trainees of English Education are exposed to second language readings with an adherence towards utilizing prior knowledge and drawing upon schemata to support their comprehension. Results from quantitative and qualitative data measured and collected from two groups of university students respectively, indicated certain advantages to this strategy use in respect of increased understanding, familiarity, and comfort level in SL reading. However, those same results identified existing limitations associated with cultural bias, stereotyping and a tendency to focus on wrong information when activating said schemata. As such, the purpose of this study is to promote awareness of the schema theory as an effective strategy option whilst reinforcing a need to pay heed to the concerns associated with strict reliance upon such theory to aid reading skills. Further discussion of these issues and pedagogical implications has been provided along with both suggested considerations regarding teaching for EFL teachers and evaluators.

We present the case of a 45-year-old man with a history of benzene exposure who developed splenic marginal zone lymphoma. For 6 years, he had worked in an enclosed space cleaning instruments with benzene. He was diagnosed with splenic marginal zone lymphoma 19 years after retirement. During his time of working in the laboratory in the 1980s, working environments were not monitored for hazardous materials. We indirectly estimated the cumulative level of past benzene exposure using job-exposure matrices and technical assumptions. Care must be taken in investigating the relevance of occupational benzene exposure in the occurrence of indolent B-cell lymphoma. Because of the long latency period and because occupational measurement data do not exist for the period during the patient's exposure, the epidemiological impact of benzene exposure may be underestimated.

이연구의 목적은 의료인을 제외한 병원종사자들의 역할인식이 직무만족에 미치는 영향을 알아보고자 시행되었다. 연구대상은 486명의 의료지원 부서를 대상으로 하였다. 다중회귀분석 결과 정책결정이 직무만족에 가장 많은 영향을 미치는 것으로 나타났다. 결론적으로 비의료직 종사자들의 직무만족도를 높이기 위해서는 병원관리자들이 그들의 역할인식 정도를 높이기 위해 노력해야 할 것이다. 이연구의 한계점은 직무만족을 세부적으로 측정하지 않아서 직무만족에 더 중요하게 영향을 미치는 변수를 보여주지 못했다.

과학관은 학생들이 학교 과학 수업 이외에 과학을 경험할 수 있는 대표적인 학교밖 과학활동이다. 이에 본 연구에서는 제7차 교육과정에서 제시한 중학교 지구과학내용체계와 영역별 성취기준을 근거로 과학관 패널전시물을 분석하였다. 그 결과 교육과정에서 제시한 성취수준과 전시의 연계성이 미흡하였고, 지질영역 전시에 편중됨을 파악하였다. 따라서 교육과정을 고려한 전시물이 요구된다. 차후 이 연구의 결과는 과학관의 전시 및 교육의 방향과 개선 방안을 위한 기초 자료를 제공한다.

English is the accepted common working language of the maritime world and being competent in its use is essential to the safety of ships, their crews and the marine environment. This paper is a response to the urgent need to find a suitable solution to the problem of providing maritime students with quality instruction in Maritime English. This paper will show what type of English instructor is best suited to help cadets have at least a basic grasp of Maritime English communication, with a view to possessing the level required by STCW 95 within the shortest time. It presents ways that maritime institutes can develop their own qualified or 'marinated' English Instructors and what qualifications should be required. It is concluded that by further essential research, interviews and questionnaires etc., the language needs of the university and shipping industry in Korea as a whole can be clearly verified. By examining such data, the present language education systems can be evaluated as to efficacy and relevance, allowing the establishment and implementation of 'best practice' within the training institute. This will result in making excellent informed decisions and choices about how best to improve the language competencies of graduating cadets, thereby creating the catalyst for the success of future seafarers whilst raising the image of the institute and Korean shipping worldwide.

Objectives: This study was aimed to investigate the effects of Galhwahyejung-tang (GHT) on alcohol-induced oxidative stress in rat model. Methods: Twenty SD rats were orally administrated with 40% ethanol (mL/kg) combined with GHT (50, 100, 200mg/kg) or distilled water for 2 weeks. Biochemistry in blood, malondialdehyde (MDA), total reactive oxygen species (ROS), and total antioxidant capacity (TAC) in serum, liver, brain, and kidney were determined. Results: GHT treatment significantly ameliorated the alcohol-induced alteration of hepatic enzyme; especially AST and ALT. GHT treatment also ameliorated the increase of MDA in liver, ROS level in serum and brain. GHT treatment reduced the depletion of antioxidant capacity in serum and brain. Conclusion: These results that GHT has antioxidant properties explaining the relevance of clinical application and its partial mechanisms of GHT.

This study was conducted to investigate the correlation between frequency of high-caffeine energy drink intake in adolescents and their mental health status using data from the Korean adolescent health behaviors online survey (2014-15). Mental health was classified by the five categories: Perception of stress (PS), Insufficient relief of fatigue after sleep (IRFS), Experience of sadness despair (SD), Suicidal ideation (SI), and Subjective unhappiness (SU). Regarding general characteristics, higher age, height, and body weight of subjects were associated with higher frequency of high-caffeine energy drink (HCED) intake (p< .0001). In the OR analysis, when the lowest group (${\leq}2/wk$) and highest group ($1{\geq}day$) were compared, the highest group showed significantly higher OR in all five categories of mental health. According to gender, males did not show better PS, SD, and SI than females who had a high frequency of HCED (p for trend<.0001). According to school level, middle school students showed a higher risk rate than high school students in PS, IRFS, and SD (p for trend< .0001). Based on the above results, higher frequency of HCED intake among adolescents was associated with more adverse effects on mental health.
