  • Combinatorics, the basis of probabilistic thinking, is an important area of mathematics and closely linked with other subjects such as informatics and STEAM areas. But combinatorics is one of the most difficult units in school mathematics for leaning and teaching. This study, using the designed combinatorial models and executable expression, aims to analyzes the eye movement of graduate students when they translate the written combinatorial problems to the corresponding executable expression, and examines not only the understanding process of the written combinatorial sentences but also the degree of difficulties depending on the combinatorial semantic structures. The result of the study shows that there are two types of solving process the participants take when they solve the problems : one is to choose the right executable expression by comparing the sentence and the executable expression frequently. The other approach is to find the corresponding executable expression after they derive the suitable mental model by translating the combinatorial sentence. We found the cognitive processing patterns of the participants how they pay attention to words and numbers related to the essential informations hidden in the sentence. Also we found that the student's eyes rest upon the essential combinatorial sentences and executable expressions longer and they perform the complicated cognitive handling process such as comparing the written sentence with executable expressions when they try the problems whose meaning structure is rarely used in the school mathematics. The data of eye movement provide meaningful information for analyzing the cognitive process related to the solving process of the participants.

  • Ingestion of grapes or raisins has been reported to the occurrence of acute renal failure (ARF) in dogs, although the mechanism remains undetermined. The prognosis often depends on the severity or clinical course of the disease at the time of presentation and is poor if the dog becomes anuric phase. To explore the characteristics and outcome of ARF caused by grape or raisin poisoning, sequentially collected data, from 2005 to 2008, of the Veterinary Medical Teaching Hospital at the Kangwon National University for clinical evaluation were retrospectively analyzed. Of the 11 clinically affected dogs, 4 cases made a full recovery, 3 died and 4 were euthanized. All but one case (raisin ingestion) had a history of grape exposure, but the exact quantity of fruit ingested was not known. The female dogs accounted for 72.7% (8 cases). Overall, the mean age was 5.3 years (range 0.2-11.3 years), and the mean body weight was 4.1 kg (range 1.4-13 kg). The average duration of hospital stay was 7.1 days (range 2-22 days). Vomiting and anorexia was reported in all dogs. Diarrhea (4 cases), oliguria (5 cases), and anuria (4 cases) with or without isosthenuria were also reported. Five dogs of 11 had mild to moderate anemia, with a decrease in packed cell volume and hemoglobin. All dogs had elevations in serum phosphorous, creatinine, and blood urea nitrogen values, but calcium values were variable; 2 dogs with hypocalcemia, 2 dogs with hypercalcemia, and the remaining 7 cases within reference interval. Dogs (n = 8) with measured on blood gas parameters had metabolic acidosis. In addition, higher serum enzyme activities were observed; amylase in 8 (72.7%) dogs, alkaline phosphatase in 7 (63.6%) dogs, and alanine aminotransferase in 5 (45.5%) dogs. Non-survived dogs revealed lower counts of platelet and lymphocyte subpopulation, as compared to the survived dogs.

  • Objectives : To investigate the knowledge and recognition level of fluorine by teaching career among class teachers, who are primarily responsible for oral health education, despite lack of expertise in oral health, by playing a model role for students through continuous contacts with them, and provide basic elementary data about accurate knowledge and how to correctly use fluorine remarkably effective in preventing dental caries. Methods : A self-administered survey was conducted with 539 teachers at 21 elementary schools in Jinhae City from September 1 to October 15, 2010, drawing the following conclusions. Results : 1. As for the channel for acquiring knowledge of oral health, the highest frequency was found in health programs for respondents with less than 9 years of career, in dental clinics for those with 20 to 29 years of career, and in PR booklets for those with 10 to 19 years and 30 years and longer of career. 2. Use of fluorine-containing toothpaste and fluorine spread is very effective and effective in preventing dental caries got 64.9%, 72.2%, 72.3%, 77.7% and 54.0%, 63.1%, 62.2%, 69.7%, respectively, among elementary school teachers with less than 9 years, 10 to 19 years, 20 to 29 years, and 30 years and longer of career. 3. Intake of fluoride and toothbrushing with fluoric solution is very effective and effective in preventing dental caries got 33.3%, 40.1%, 39.5%, 55.3% and 50.0%, 54.9%, 48.8%, 69.7%, respectively, among elementary school teachers with less than 9 years, 10 to 19 years, 20 to 29 years, and 30 years and longer of career. 4. Use of fluoric tablets is very effective and effective in preventing dental caries got 32.9%, 36.0%, 36.1%, 47.3%, respectively, among elementary school teachers with less than 9 years, 10 to 19 years, 20 to 29 years, and 30 years and longer of career. 5. Most of the elementary school teachers knew the fact that fluorine increases dental resistance to cavity and prevents bacterial growth but gave incorrect responses to properties of becoming basic nutrients or inducing recalcification. Conclusions : Various types of application of fluorine during the elementary-level childhood experiencing the most frequent dental caries will be very useful in improving oral health in the future. It is necessary to enable class teachers to get correct recognition of fluorine through supplementary and job training based on technical knowledge and various educational materials so that they, who are directly responsible for health management through continuous contacts with students, can understand how to correctly use fluorine and get accurate knowledge.

  • The performing art is a genre which is integrated of various fields of arts, and Stage Make-up as well. Stage Make-up functions as an important means of communication which makes audience understand the characteristic facts by transforming an actor/actress into the character in the play and also, visually enlarging characters. Due to the creativeness of Stage Make-up, the conceptual study on Stage Make-up design for visual expression coincide with the intended character is needed. However, in Korea, the systematical approach for Stage Make-up design by character types has not developed, or studied yet, The result of this study is to present system model through theoretical study of psychological personality types. and to apply for the expression of characters in the play based on physiognomy(face-reading), The case study of visualizing according to an actor/actress's shape of face. is Specially focused on eyes and eyebrows. In designing Stage Make-up, eyes and eye brows are important elements as a tool for strong expression of the characters. This model of Stage Make-up design by personal type constructed in this study, is for applying methodically as professional approach on actual Stage Make-up design and educational teaching methods as well.

  • A mariner cadet gains the ability to identify and avoid potential collisions with other ships through ARPA/Radar simulation education. This research surveyed first domestic and overseas's rules (e.g., MOMAF's Standard, the STCW Convention, etc.) of the simulation education, upon investigation the only content and timing of this simulation-based education are specified according to these rules, and maritime education institutions issue the related certification autonomously after a student has taken the simulation because no simulation education module exists to further guide the ARPA/Radar simulation. As a result, it is difficult for students to acquire consistent maritime ability through ARPA/Radar simulation. This paper discusses standardization of these education modules to produce more consistent mariner ability, and verify the degree of improvement of education that would be achieved by enacting the proposed education module. The simulation education system used in maritime institutions in Korea was investigated, and scenarios reflecting traffic flow in actual waterways was proposed based on marine traffic surveys so teaching modules can educate/assess more effectively based on core marine abilities. Improvements in education and training were also verified using data collected over 2 years based on a standardized module. Each education institution can enact an effective, systematic education approach using standardized ARPA/Radar education modules proposed in this paper, and this can set a foundation to contribute to safer vessel navigation by improving maritime abilities.

  • This study was aimed at developing a common curriculum for the department of environmental education from 5 colleges of education. The need and background of curriculum reform can be summarized as follow; first, it has been recognized that new national curriculum of 2009 and 2011 created need for training teachers equipped with more integrated competency. Second, global environmental problems such as climate change and energy crisis asked for more responsible choice and action from all citizens. Third, the extremely low hiring rate resulted in the consideration of new working fields for teacher students majoring in environmental education. Fourth, the expansion of new environmental education paradigms including education for sustainable development called for practicing reconstruction of both contends and methods. From a series of research processes including analysis of current curriculum, DACUM, opinion survey and interest groups review, several new approaches for developing new curriculum had been identified as follow; first, content areas of environmental education should be extended beyond environmental natural science. Second, new learning approaches such as project-based learning need to be emphasized for strengthening the identity of environment as a separate subject. Third, more selective majoring system need to be applied in connection with environment government officials, researchers, and social environmental educators. It was recommended that the application of new curriculum developed by the study would be evaluated and managed by teaching conditions surrounding each of the five university members joined this developing processes. However, it needs to be noted that there is not much time because we had experienced zero hiring rate for the last 4 years and environmental policy and education programs are moving rapidly toward sustainable development.

  • The purpose of this study is to develop the first domestic professional hospice educational program. We investigated the present condition of Korean hospice education and analyzed the prerequisite need for a dedicated hospice course in the professional education process. Research was conducted between June and November 1996 for nursing professors teaching at each nursing education institute to find out how much hospice is being discussed and by whom, in which course it is being discussed, and also to find out the contents that needed to be included in the professional education process. From a total of 49 colleges(29 three year colleges, 20 four year colleges) out of 99, 162 nursing professors replied, the collection rate was 49.5%. The conclusions are as follows ; 1. The present condition of the hospice nursing education. 1) Whether hospice is included in the education program. \circled1 89.65% of 3 year colleges and 90% of 4 year colleges included hospice education in their education program. \circled2 In graduate studies three schools included hospice in their program and three schools expressed their plans to include hospice education 2) Hospice related education were commonly discussed in adult nursing(26.3%), fundamental nursing(22.8%), and psychiatric nursing(20.2%). In 3 year colleges its commonly discussed in the first and second year and in 4 year colleges it is taught in the second and third year. 3) Hospice related theory/practical education hours were averages of 6.5/7.0 hrs in 3 year colleges and 14.2/11.3 hrs in 4 year colleges. 4) The majority of professors in charge of hospice education were in the following order adult nursing, psychiatric nursing, and fundamental nursing. 5) The courses that are thought to be adequate to manage hospice related education were adult nursing(29.3%), community health nursing(21.7%) and the desired method of education was the method currently being used (36.5%). 2. The demand for hospice nursing education. 1) Over 70% demanded professional hospice education program, the highest demand was for the value and meaning of life followed by the role and qualification of the hospice team and the mental maintenance of a dying patient. 25 categories showed over 90% demand. 2) The highest demand was for the value and meaning of life (98.2%) and the lowest demand were for danjeon breathing(71.0%)and acupuncture(71.0%). 3) Other contents that need to be discussed in the professional hospice education program were hospice nursing, the attitude and reaction of death, bereavement care, and the prospects of hospice.
