In this study, we analyzed the written and drawn explanations of thirty elementary school pre-service teachers in order to examine their perception on the seasonal length of day and night. The main findings are as follows: First, pre-service teachers used the most common term in the description of the texts, such as meridian altitude, axis of rotation, and revolution, and there were more misconceptions in the drawn explanation than in the written explanation. Second, by analyzing the pre-service teachers' perceptions by combining written and drawn explanations, it is possible to detect scientific errors that the distance between the Earth and the Sun is closer when the axis of rotation is tilted in relation to the revolution and seasonal changes due to changes in the orbital radius of the Earth. In addition, there have been types of explanations such as seasonally changing meridian altitudes related to the rotation of the Earth but no change in the location of the Sun. Based on the results of the analysis, we discussed the lack of experience in constructing an explanatory system of specific phenomena using scientific knowledge, lack of observational experiences about natural phenomena, and lack of exposure to other explanatory systems that cause cognitive conflicts. We hope that it will be concrete and practical help to improve the understanding of pre-service teachers in the science domain of primary teacher training program.

This study investigates how common English hedge expressions such as 'I think' and 'I guess' appear in Korean, with the aim of providing explicit explanation for English-speaking leaners of Korean. Based on a contrastive analysis of spoken English and Korean corpus, this study argues three points: Firstly, 'I guess' appears with a wider variety of modalities in Korean than 'I think'. Secondly, this study has found that Korean textbooks contain inappropriate use of registers regarding the English translations of '-geot -gat-': although these markers are used in spoken Korean, they were translated into written English. Therefore, this study suggests that '-geot -gat-' be translated into 'I think' in spoken English, and into 'it seems' in the case of written English and narratives. Lastly, the contrastive analysis has shown that when 'I think' is used with deontic modalities such as 'I think I have to', Korean use '-a-ya-get-': the use of hedge marker 'I think' with 'I have to', which shows obligation or speaker's volition turns the deontic modalities into expressions of speaker's opinion.

Based on the previous translation studies and "WHO-IST", we selected terminology, which are required the definition and explanation among jargon expressed in "Dongeuisusebowon Discourse on Nature and Act", and the procedure of the definition, explanation, and translation in Korean and English has been followed. The outcomes of this study are presented as below: First, based on the existing translation studies, Korean and English translation of "Dongeuisusebowon Discourse on Nature and Act" is provided. Second, few of Terminology in "Dongeuisusebowon(東醫壽世保元)" have been written in WHO-IST, even most of them have been standardized in terms of "Huang Di Nei Jing(黃帝內經)". Therefore, terminology related to Four-constitution medicine in WHO-IST would be required to be corrected, and unattatched terminology should be added in the future. Third, in order to standardize and globalize Four-constitution medicine, further definition, explanation, and translation studies of the rest of Dongeuisusebowon should be continued.

The purpose of this study was to compare receptive language performance and expressive language performance in 13 patients with aphasia by using three stimulus presentation modes: Stimulus mode I (picture), Stimulus mode II (written word), Stimulus m (question using verbal explanation). The stimulus consisted of 10 words. They included 5 functional words and 5 non-functional words. The 13 subjects with aphasia were divided into 2 aphasic types: 5 Broca's aphasics and 8 anomie aphasics. The results were as follows: Firstly, the three stimulus modes didn't affect receptive language performance of aphasia subjects. Secondly; the three stimulus modes were effective on expressive language performance of aphasia subjects. Particularly, stimulus mode II (written words) was effective in naming the aphasia subjects. Thirdly, the functional words with high frequency were better than non-functional words with low frequency on expressive language performance, but not on receptive language performance of aphasia subjects. Finally, the interaction between three stimulus modes and the functional (nonfunctional) words affected expressive language performance only, but not receptive language performance. Particularly, presenting stimulus in written words which are functional words produced the best expressive language performance.

This study was carried out on hospitalized patients receiving diet therapy satisfaction and awareness of nutrition education in small and medium-sized hospitals in southern Gyeonggi area. By the face-to-face interview with questionnaire method, the survey was carried out on 150 subjects (99 males and 51 females). The patients (64.7% of males, 52.9% of females) heard the description of diet therapy without the aid of written manual. Patients were moderately satisfied by food that was rated based on these indicators: tastiness (2.45), saltiness (2.23), smelliness (2.23), and appetizing appearance (2.39) as a 4 point scale. Most of the patients (80.8% of males, 69.8% of females) wanted to continue diet therapy. The importance of diet was correlated with the tastiness, saltiness, and appetizing appearance of diet. And the help of dietitians' explanation was correlated with appetite. 55.6% of males and 35.4% of females received nutrition education before (p<0.05). The number of times nutrition education was received was once for male (33.3%) and three times for female (44.4%). Most nutrition education satisfaction that was calculated on a 4 point scale was well understood (3.03), recognized importance (3.44 for males, 2.78 for females) and help for disease management (p<0.01). Also they were satisfied with the explanation of disease (3.20). Nutrition education satisfaction was correlated positively with explanation about food related to disease, the current dietary treatment, how to prepare diet recipes, and dietitian's kindness, but negatively with satisfaction with explanation of diet therapy, and the description and help for disease management. In conclusion, the most important factor in practicing diet therapy was meeting with the dietitian. Intensive nutrition education after the patient's discharge is necessary for patients to continue diet therapy.

The purpose of this study was to examine the types of explanation about different experimental data on students' preconceptions on physical experiment. 45 students were selected from P University by examining their pre-test. The subjects had a scientific conception about a simple pendulum's period of movement, and expected that there was no change in the movement even when the mass of water increased in the can. The students were presented data about pendulum movement inside a can. They recorded this in a blank table and drew a graph about the movement of the pendulum. The responses of students were tested by presenting written anomalous experimental data. Students' recognition, trust about the anomalous data, cognitive conflict, belief change about their preconceptions were examined with written tests also. To measure students' cognitive conflict levels, CCLT (Cognitive Conflict Levels Test) developed in a previous study was used. Some students responded based on preconceptions and regarded the data as manufactured data or experimental error. The students who recognized the anomaly in the situation showed higher cognitive conflict levels than those who didn't recognize the anomaly in the situation. The students who changed their beliefs about preconceptions recognized the data as anomalous situations and showed high cognitive conflict levels than those who didn't abandon their preconceptions. The students who have unchanged beliefs about their preconceptions regarded the data as experimental error.

"e-Leaning" system is classified by lecture time into two types, that is, "synchronous type" spent the same lecture time between the lecturer and students, and "asynchronous type" spent the different lecture time. The size of image database is huge, and there are some problem on the management of the lecture image database in "asynchronous type" e-Learning system. The one of them is that the time tag for the database management must be added manually at present, and the cost of the addition of the time tag causes a serious problem. To resolve the problem, we will use the character recognition for the characters written by the lecturer on whiteboard, and will add the recognized character as a keyword to the tag of the image database. If the database would have the keyword, we could retrieve the database by the keyword efficiently, and the student could select the interested lecture scene only in the full lecture database.

Objective This study was aimed to research how the recognition of Taeeumin's Mongsul disease was changed from the Gabo edition to the Sinchuk edition of Donguisusebowon, and to present reasonable explanation to the prescription suggested in the Sinchuk edition. Method The original text about Taeeumin Mongsul disease and corresponding prescription in Donguisusebowon Sinchuk edition written in 1901 and Donguisusebowon Gabo edition written in 1894 were compared and analyzed. Furthermore, the literature and articles which are relevant to the prescription and the difference of pathology between the Gabo edition and the Sinchuk edition of Donguisusebowon were searched. Results & Conclusion Sinchuk editon compared to Gabo edition differentiates prescriptions according to the condition of stool, which means that Mongsul disease can occur both in Lung-dryness of Esophagus-Cold pathology and that of Liver-Heat pathology. The prescriptions presented in Sinchuk edition are more specified and in agreement with pathology newly proposed in Sinchuk edition than the prescriptions in Gabo edition. Although Cheongsimyeonja-tang is not mentioned on the original text about Taeeumin Mongsul disease in Sinchuk edition, it can be prescribed for the disease with Lung-dryness of Liver-Heat pathology as Yuldahanso-tang can be. However, Yuldahanso-tang focuses more on Liver-Heat symptoms, while Cheongsimyeonja-tang focuses more on Lung-dryness.

Hushoujing(狐首經) is Fengshui documents traditionally known to be written by Baihe(白鶴) of Han(漢) dynasty, which is hardly known in Korea. Baihe, the author, like Qingwuzi(靑烏子) has no evident personal background in history. There is a copy known to be written by Baihe of Han dynasty included in Dilitongyiquanshu(地理統一全書), which was published in 1628. The editor is known as Yuxiangtou(余象斗) from Fujiansheng(福建省) Jianyangxian(建陽縣) the same home town as Zhuxi(朱熹)'s. In contents and system, Hushoujing has the deep(profound) relationships between Qingwujing(靑烏經) and Zangshu(葬書), which attracts attention nowadays. Studying the relationships between Qingwujing, Zangshu and Hushoujing is the realm which requires systematic approach. Another reason for Hushoujing's attraction in Fengshui research lies in the contents related with Liqilun(理氣論). Mentioning Xingqilun(形氣論), Hushoujing also includes the explanation of Chinese compass needle, Deshui(得水) and Pokou(破口), and it is directly connected with the main theme of Liqilun. Hushoujing reveals a view point that both Xingqi(形氣) and Liqi(理氣) are important. Accordingly this means that we can understand Liqilun more clearly through studying Hushoujing. It is clearly recorded in the documents of Song(宋) dynasty that there was odd notes documents of Hushoujing as well as mentioning it. Therefore it is very likely that Hushoujing had been written before Song dynasty. Being contained in Huxianshengyinyangbeiyong(胡先生陰陽備用), Dilicanzanxuanjixianp oji(地理參贊玄機仙婆集), Dilitongyiquanshu, Lidaidilizhengyimishuershisizhong(歷代地理正義秘書二十四種), Xingjiaershizhong(形家二十種), 5 kinds of Hushoujing's copies are descended. The contents of Hushoujing are also introduced in documents of sejong period in The Annals of the Choson Dynasty. This means that Hushoujing is the geographical books prevailed representatively in early years of Choson Dynasty and studying Hushoujing is indispensible to studying Fengshui history or Chinese compass(羅盤) as well as deep understanding of Fengshui theory.
