Previous research has recently shown that non-cognitive factors such as attitudes toward statistics contribute positively to statistics learning, Hence, helping students develop positive attitudes toward statistics has become one of the essential goals of statistics teaching. A wide variety of instruments assessing attitudes toward statistics were developed and validated in foreign countries, but not many in Korea. The SATS-36(Survey of Attitudes Toward Statistics-36; Schau et al., 1995) has been regarded as one of the most valid measures of attitudes toward statistics. Therefore, this study was designed to validate a Korean version of Survey of Attitudes Toward Statistics(K-SATS). Instead of six factors of the original scale, a five-factor structure including interests, value, cognitive competence, difficulty, and effort was empirically supported by the Korean student sample. The results evidenced high reliability and construct validity of K-SATS. In addition, students' attitudes towards statistics differed across gender, level of statistics courses, degree programs, and major. These findings were discussed in terms of their implications for future research and statistics teaching.

Background: Hominis placenta (HP) is used in Korean medicine to tonify qi and blood, and enrich yin and tonify yang. HP has been reported to have therapeutic effects. Methods: A survey of international and Korean electronic databases was conducted using the search terms "hominis placenta pharmacopuncture" and "hominis placenta extract". The search was limited to material published up to May 31, 2017. Results: A total of 83 studies were included in this systematic review: 50 were clinical studies, 25 were basic studies, and 8 were other types of study. Among clinical studies, the most frequently treated disease groups were musculoskeletal diseases and nervous system diseases. In vitro studies were conducted mainly on anti-inflammatory, analgesic, and anti-cell necrosis models. Most of the in vivo studies were performed in rheumatoid arthritis or diabetic complications models. Conclusion: HP pharmacopuncture has effects in the treatment of various diseases. Further large-scale randomized controlled trials are needed to improve the level of evidence for HP pharmacopuncture. It would be helpful if future in vitro and in vivo studies could identify the mechanism of action of HP pharmacopuncture.

In the beginning brain waves were used for monkeys to control robot arm with neural activity. In recent years there are research that measured brain waves are used for the control of programs which monitor the progression of dementia or enhance of attention in children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). Moreover, low-price devices that can be used as a game control interface have become available. One of the problems associated with control using brain waves is that the mean amplitude, mean wavelength, and mean vibrational frequency of the brain waves differ from individual to individual. This paper attempts to propose a method to normalize measured brain waves using normal distribution and calculate the waveforms that can be used in controlling games. For this, a framework in which brain waves are converted in seven stages has been suggested. In addition, the estimation process in each stage has been described. In an experiment the waveforms of two subjects have been compared using the proposed method in the BCI English word learning program. The level of similarity between two subjects' waveforms has been compared with correlation coefficient. When the proposed method was applied, both meditation and concentration increased by 13% and 8%, respectively. Because the proposed regularization method is converted into a waveform fit for control functions by reducing personal characteristics reflected in the brain waves, it is fitting for application programs such as games.

The purpose of this study is to analyze the equality between keywords used in the Journal of the Korean Academy of Pediatric Dentistry and medical subject headings (MeSH). A total of 4,353 English keywords in 1,165 papers from 1998 to 2014 were eligible for this study. We classified them according to equality to MeSH. We assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. 24.9% of total keywords were completely coincident with MeSH terms, 75.1% were not MeSH terms. The results show that the accordance rate of keywords with MeSH terms in the Journal of the Korean Pediatric Dentistry is at a low level. Therefore, there is a need for authors to understand MeSH more specifically and accurately. Use of proper keywords aligned with the international standards such as MeSH is important to be properly cited. Authors should pay attention and be educated on the correct use of MeSH as keywords.

Background: Faced with highly prevalent and recalcitrant cancer-related fatigue (CRF), together with the absence of any official guidelines on management, numerous groups have been striving to seek and test alternative therapies including acupuncture and moxibustion. However, different patients have various feedbacks, and the many clinical trials have given rise to varied conclusions. In terms of the therapeutic effect of acupuncture and moxibustion, there exist vast inconsistencies. Objective: The aim of the study was to evaluate the auxiliary effectiveness of acupuncture and moxibustion in the treatment of CRF, and to provide more reliable evidence to guide clinical practice. Methods: Randomized controlled trials (RCTs) published before December 2012 were all aggregated, focusing on evaluation of acupuncture or moxibustion for CRF. The quality of the included studies was assessed basing on Cochrane handbook 5.1.0, and the available data were analyzed with RevMan software (version 5.2.0). Descriptive techniques were performed when no available data could be used. Results: A total of 7 studies involving 804 participants were eligible. With real acupuncture versus sham acupuncture, subjects receiving true acupuncture benefited more in the reduction of fatigue. With real acupuncture versus acupressure or sham acupressure, fatigue level appeared 36% improved in the acupuncture group, but 19% in the acupressure group and only 0.6% with sham acupressure. When real acupuncture plus enhanced routine care was compared with enhanced routine care, the combination group improved mean scores for general fatigue, together with physical and mental fatigue. With real acupuncture versus sham acupuncture or wait list controls, the real acupuncture group displayed significant advantages over the wait list controls at 2 weeks for fatigue improvement and better well-being effects at 6 weeks. When moxibustion plus routine care was compared with routine care alone, the meta-analyses demonstrated the combination had a relatively significant benefit in improving severe fatigue and QLQ-C30. Conclusion: Up to the search date, there exist few high quality RCTs to evaluate the effect of acupuncture and moxibustion, especially moxibustion in English. Yet acupuncture and moxibustion still appeared to be efficacious auxiliary therapeutic methods for CRF, in spite of several inherent defects of the included studies. Much more high-quality studies are urgently needed.

Purpose: To evaluate the vision-specific Quality of Life according to modes of refractive error correction in myopia. Method: This study included subjects from two different universities in Korea during March 2005 to June 2005. The following subjects (470) were university students, university faculty members, and their immediate families; all of whom were over the age of 19 and all who had refractive error of some sort. The four focus groups consisted of 171 spectacle wearers, 154 contact lens wearers, 123 refractive surgery patients, and 22 post-refractive surgery patients who returned to wearing glasses. The study of Vision-Specific Quality of Life used QIRC - The Quality of Life Impact of refractive Correction Questionnaire, which was translated by our group from English into Korean. Using analysis of co-variance (ANCOVA) and adjusting for age, sex, job, economic status, and education level, we examined and compared the QOL mean scores of the three groups (glass & contact lenses wears, refractive surgery patients, and post-refractive surgery patients who returned to wearing glasses). Results: After adjusting for major compounding variance, the research results showed the highest QOL mean score of 43.2 for the group who had received refractive surgery, 37.1 for the glasses & contact lenses group, and 33.4 for patients who had returned to wearing glasses after refractive surgery. There were significant differences between the three groups (p=0.001). Conclusion: Refractive surgery has shown a significant contribution to improve the QOL in myopia patients. However, upon our investigation, patients who underwent refractive surgery and returned to wearing glasses had a lower QOL compared to non-refractive surgery patients who wore glasses/contact lenses. Upon concluding our studies that shows that refractive surgery does not always conclusively bring higher QOL, we would like patients to carefully consider their options before undergoing refractive surgery in the future.

The purpose of this study is to identify the variables of metropolitan and provincial offices of education that affect the academic achievement of unit schools, and to predict how academic achievements dynamically change with the support of offices of education. The results of academic achievement of 606 general high schools in 16 metropolitan and provincial offices of education(rates of attaining more than normal education in Korean, English, and mathematics subjects) were analyzed using a multi-level model and system dynamics. As a result of the analysis, it was confirmed that the provincial and provincial offices of education's efforts to increase the efficiency of local education finance, the efforts to reduce teacher administration, and the facilitation of faculty training were the variables of the provincial and provincial offices of education. In addition, through policy experiments, efforts to revitalize teacher training were the most influential factors in academic achievement of unit schools, followed by efforts to streamline local education finances and to reduce the administrative work of teachers. In order to improve the academic achievement of unit schools, the functions of the metropolitan and provincial offices of education should be strengthened based on the education accountability, and policies need to be established in the mid- to long-term perspective.

This paper is a study on the perception of current competency and expected competency of engineering freshmen by extracting core competencies acquired from university education. It also aims to suggest proper way for engineering university education. This study extracts competencies in the following five areas as core competencies: 'knowledge on major area', 'cultural ability', 'foreign language ability', 'basic learning ability', 'intercommunication ability'. To achieve this purpose, this study surveyed 'C' university engineering department freshmen (584 students) with questionnaires about their perception of core competencies. The results are as follows. First, engineering freshmen perceived current competencies were weak in every area, especially their capacities in 'foreign language ability' area were perceived to be weakest. Their demand for education is the highest in 'foreign language ability' area, and the second higher in 'knowledge on major area'. Secondly, there exists meaningful difference between perception of current competency and expected competency depending on the gender, high school department (science/liberal arts), high school location, types of college admissions, and types of mathematics in NAST. According to these results, this study suggests enhancement of foreign language (English) education in engineering department, design and implementation of various educational program to overcome individual difference, promoting importance of competencies in the 'cultural abilty' and 'intercommunication abilty', necessity of continuous adjustment and complementation for engineering educational program through accumulation of feedback processes, activation of career education through engineering education and special programs.

The purpose of the study is the find out current status and key factors of attendance in private education of gifted students. The results show that 95.9% of gifted students and 94.6% of general students are currently participating in private education. Most percentages of students took English and math programs at the private institutes. Average amount of time students spend for private education was 2~3 hours per day, and most percentage of parents spent 400,000~600,000 won per month for their children's private education. There were no significant differences between the gifted and the general students in the aspects of private education statuses. Regarding the key factors of attendance in private education, improvement of study related skills, school grade management, and influences of surroundings, such as parents and friends, were showed as significant variables in gifted students group. Interestingly, influences of surroundings showed negative effect. For general students and their parents, improvement of study related skills and school grade management factors were significant variables. And for the parents of gifted students, improvement of study related skills and entering higher level schools appeared as significant factors for the participation in private education. Implications of the study were discussed in depth.

Recently the rapid changes of the social environment make both university and every each department should have to renovate and adjust all of the educational components. The most dominant and issuable change of business administration education is the Business Education Accreditation which was certified by the KABEA(Korean Association of Business Education Accreditation). And the only two department of fisheries business administration which in Gyeongsang National University and Pukyong National University has been accredited recently. Though The department of fisheries business administration in Korea has been influenced by that Accreditation, there is few research and analysis on educational change. So it is very important that research on the curricular constitution and change of the curriculum for considering the its own effect and influence. This paper aims to explore the curricular constitution, change and course fulfillment of fisheries business administration after the business education accreditation based on the case of the department of fisheries business administration in Gyeongsang National University. The analysis of fisheries business administration change will help develop sustainable curriculum and give more guideline for identifying the core of fisheries business administration. The method of analysing that in this research has adopt the social network analysis(SNA) and automated software tool which is the most dominant technique in contents analysis including the Krkwics and Pajek. The SNA is evaluated that most popular, rigorous and firm methodology for analyzing, examining and revising some concepts or objects in the context of semantics. The result of this study shows that the ratio of fisheries business administration class has been decreased but still the most fulfilled course. And English mediated class has been avoided though that sort of the class has been increased. In the view point of course fulfillment, it has been potential and inefficient problems that some classes that including financial related and accounting related class would not been accomplished appropriately. The findings of a graduate depth interview which has been done about 4 years for understanding that student show that there's some recognition gap of fisheries business administration in staffs of human resource management. And the level of job satisfaction in fisheries business still somewhat low and even worse the chance of recruitment also unsteady.
