The purpose of this study is to investigate what influences students' preferences on empirical and deductive proofs and find their relations. Although empirical and deductive proofs have been seen as a significant aspect of school mathematics, literatures have indicated that students tend to have a preference for empirical proof when they are convinced a mathematical statement. Several studies highlighted students'views about empirical and deductive proof. However, there are few attempts to find the relations of their views about these two proofs. The study was conducted to 47 students in 7~9 grades in the transition from empirical proof to deductive proof according to their mathematics curriculum. The data was collected on the written questionnaire asking students to choose one between empirical and deductive proofs in verifying that the sum of angles in any triangles is $180^{\circ}$. Further, they were asked to provide explanations for their preferences. Students' responses were coded and these codes were categorized to find the relations. As a result, students' responses could be categorized by 3 factors; accuracy of measurement, representative of triangles, and mathematics principles. First, the preferences on empirical proof were derived from considering the measurement as an accurate method, while conceiving the possibility of errors in measurement derived the preferences on deductive proof. Second, a number of students thought that verifying the statement for three different types of triangles -acute, right, obtuse triangles - in empirical proof was enough to convince the statement, while other students regarded these different types of triangles merely as partial examples of triangles and so they preferred deductive proof. Finally, students preferring empirical proof thought that using mathematical principles such as the properties of alternate or corresponding angles made proof more difficult to understand. Students preferring deductive proof, on the other hand, explained roles of these mathematical principles as verification, explanation, and application to other problems. The results indicated that students' preferences were due to their different perceptions of these common factors.

Objectives : In order to comprehend and utilize external therapy, we considered that we needed to research Wu Shi-Ji who was a medical specialist of external therapy. We looked at the special study on external therapy in his book, ${\ll}li-yao-pian-wen{\gg}$, especially ; in this part his generai approach to external therapy was well-detaiied. Methods : We translated and analyzed . Results : In , he gives a supplementary explanation about the insufficient attention paid to external therapy, 膏(gao) - (ti) 坐(zuo) (yu) 抹(mo) 纏法(chan fa), through San Jiao(三焦). And he insisted on his conception of external therapy: ointment(膏) and the moth of sneezing, sitting on herbs(坐), steaming or attaching herbs patients's navel, rubbing(抹) and binding(縛), based on ${\ll}nei-jing{\gg}$ and ${\ll}shang-han-lun{\gg}$. He put forward the general rules of external therapy using those methods. And through , he explained that the efficacy of his external therapy was basically the same as internal therapy and medicine, the only difference was in the method. In addition, this external therapy has some merits when compared with internal medicine. First, it's easier to diagnose a disease and treat patients compared to internal medicine. For instance, when a patient has a problem with his abdomen, we just have to diagnose a disease of the abdomen and treat using one method of external therapy on the abdomenal area. Second, external therapy has fewer side effects. And third, we can utilize the meridian theory when we use external therapy. Conclusions : Through , we basically understood his conception of external therapy. Although more research is needed, we suggest that we need to enlarge our usage of external therapy, not just confine ourselves to smaller areas of focus. His point of view suggests that external therapy is not merely an adjunct to internal therapy, but an interdependent course of study and action in its own right.

Since patients with strokes occupy a high priority among patients for home nursing, the development of guidelines for such nursing is required and the needs of these patients should be reflected in the guidelines. Therefore, this study was done to identify the content and levels of home nursing for patients with strokes and to utilize the data in developing the most effective home nursing guidelines for these patients. The level of A, D. L. and the ability to control upper extremities were measured, and through a questionnaire. the needs for home nursing and related variables were also evaluated. The subjects for the study were 121 patients, 58 inpatients and 63 home care patients who had had a Stroke. Data collection was done from September 1996 to January 1997. The collected data were analyzed utilizing SPSS /PC, and the results are as follows : 1. Home nursing need of inpatients The priority order of home nursing needs for inpatients was : "Training in emergency treatments and how to cope with a stroke"(2.28+1.06), next, "Explanation of diets as limited or recommended", and last, "Nursing care for sleeping Problems". 2. Home nursing need home of patients The priority order of home nursing needs for home patients was : "Care for the paralyzed side" (2, 89+.34), next, "Maintenance of right posture and how to change position" (2.87+.34), and last, "Counseling on sex". 3. Comparison of the levels of home nursing needs between in patients and home patients The results of analyses of home nursing needs according to causes were grouped into seven categories : and t-tests of the seven categories showed significant differences between the two groups in all categories, that is, the level of home nursing needs were significantly higher for home patients than for inpatients in all categories of home nursing. 4. Level of home nursing needs by characteristics The variables that have affected the level of home nursing needs for these patients were sex, profession, level of education, accompanying diseases, paralyzed position. A.D.L. levels and ability levels in coordinating upper extremities. There variables, displayed a reverse correlation with the level of home nursing needs, and the degree of correlation was high. In conclusion, the above results, show there were differences in the priority order of home nursing needs between inpatients and home patients : but the content of home nursing needs wanted by these patients was similar. Meanwhile, the levels of demand for home nursing was exceptionally higher on the part of home patients than inpatients. Although it is realized that nursing guidelines for home nursing needs in all items need to be developed, there is also a necessity to guidelines in accordance with priority orders, and with consideration of the factors that affect the level of home nursing needs. of the factors that affect the level of home nursing needs.

The Supreme Court stand in the position in specific lawsuit that it doesn't allow the discretionary not covered service, but recently in revocation suit of fine disposal that is imposed on medical fee of leukemia patient, it altered the existing adjudgement and admitted the discretionary not covered service exceptionally. It put forward the allowable condition roughly in that case. According as this alteration, it has become more important to embody the allowance conditions of exceptions. The Supreme Court presented three things, which are procedural condition, medical condition and subscriber's agreement. Concerning procedural condition, several present conciliation procedures are as follows: medical care benefit arret request, relative value conciliation etc, prior request on anti-cancer drug among chemicals which exceed acceptance criteria, request of non benefit object on common drugs. To be granted the existence of those system, there should be no obstacle to use that. Even if it were so, we should take circumstances into consideration; individual situation is unescapable concerning substance and urgency of the discretionary not covered service, process of the procedure, time required etc. Regarding medical condition, safety and effectiveness will be verified through evaluation procedures of new medical skill. About the necessity, the Supreme Court made clear through a sentence that it allow the discretionary not covered service, in case that needs to treat a patient out of the standard of medical benefit. Strict interpretation is right and it answer the purpose of the sentence that the supreme court permit the discretionary not covered service, exceptionally. We need to differentiate medical necessity and medical validity. Subscriber's agreement should holds true if it entails full explanation, and if it is preliminary, explicit and individual. On this account, it should be difficult to admit that someone agree effectively when he call for the affirmation that he is recipient of medical care. Reasonable expense needs to be a part of review whether the agreement is valid. Meanwhile If we adjust system of medical expense and eventually reorganize a fee for consultation payment system (Fee-for-service controlled by item to DRG (Diagnosis Related Groups)), controversial area of the discretionary not covered service will be decreased and that will guarantee the discretion of the doctor.

The purposes of this study were to identify the misconceptions that students have on the magma and plate tectonics and to present the implications in developing textbooks as well as related curriculum of high school textbooks. Data were collected through questionnaire, consisting of some questions, short essays, and descriptive drawings, developed by the research team. A total of 140 high school students(9th graders) responded to those questionnaires and were interviewed for further information. It was reported that participants displayed various misconceptions related to magma and plate tectonics. The identified misconceptions are as follows: For the definition of magma, the 31% of participants misunderstood magma as lava. In respect to the generative mechanism of magma at subduction zone, over 90% of students responded that it is generated by frictional heat. The source of misconceptions were identified as a result from textbooks and related reference-books. For the concept of plates, 87% of students conceived 'crust or a lower part of the plates' as 'plates'. Most participants hold the right concept of oceanic ridge, whereas, 66% of them considered 'rift valley' as either 'divergence of continental plates' or 'converging boundary'. 63% of them defined 'collision boundary of continental plate' as either 'subduction zone' or 'diverging boundary'. For the definitions of the trench and Benioff zone, 86% of students responded them as the place of subduction or differing density between two converging plates. The students' misconceptions were resulted from the errors and insufficient explanation, inappropriate figures, and data presented in textbooks, reference-books, lecture, and web sites. The results of this study are implied to contribute the improvement of students' misconceptions.

The purpose of this study is to classify welfare regimes using the method of qualitative comparative analysis(QCA). By formalizing the logic of qualitative analysis, QCA makes it possible to bring the logic and empirical intensity of qualitative approaches to studies that normally call for the use of quantitative methods. In QCA each case is conceived holistically, as a configuration of conditions, not a collection of scores on variables. Major findings of this study are as follows. Firstly, major explanations for welfare state differences are partly supported. Indicators relevant to each explanation can appear to be important only if other causal conditions are considered. For example, in the interventionist welfare states, high GDP per capita must be combined with the weakness of the Right and ethnic homogeneity. Otherwise, it can't discern interventionist from liberalist welfare states. Secondly, the equation for the interventionist welfare states includes multiple causal conjunctures. Many studies of welfare state find the same results. The third main finding is that IDV(individualism index) which is proxy for the weakness of informal network matters. Combining with other variables, IDV seems to be important in explaining the emergence of Confucian welfare states.

Students' affective attitude not only influences their achievement in a meaningful way but is also an important educational goal in its own right. This research investigated how students' interest in science varies among elementary, middle, and high-school students based on surveys and reviews of previous research results. We analyzed students learning attitude in terms of (1) interest in and enjoyment of science, (2) instrumental motivation in science, (3) science learning anxiety, and (4) self-concept in science. Major findings are that students showed more negative attitudes in intrinsic motivation, instrumental motivation, value perception of science, and confidence in science as they move in to a higher school level. According to the students' explanation, science classes get boring in higher grades because of difficult contents, lack of experiments and activities, and the teachers' monotonous explanations. Based on the results, recommendations on how to improve students' attitudes towards science are suggested. First of all, we need to secure more science instructional hours in the school curriculum than the 7th national curriculum to implement improved science teaching and learning methods.

This study was conducted on October 23, 2020 at the Cheongpyeong Reservoir located in Seorakmyeon, Gapyeong-gun, Gyeonggi-do, and analyzed the horizontal and vertical distribution patterns of fish based on data obtained using fishfinder. The total surface area of fishfinder survey conducted was 782,853 m², and where the water depth (WD) ranges from 10 m to 12 m is widest which 31.7% of total surface area. As a result of the heat map analysis, fish density was highest at right bank under the Gapyeong-bridge, but there was no specific pattern in horizontal distribution of fish. As a result of vertical distribution of fish analysis, 86.6% of fishes are observed at below 6 m of the fish depth (FD, distance from water surface to fish). As a result of the relative height (RH, water depth-distance from bottom to fish ratio) analysis, there was a tendency that fishes are distributed in near surface area more as the WD increased. This tendency could have various reasons such as water temperature gradient along the water depth, and further studies are required for detailed explanation.

The aim of this study is to compare the diseases which are in the Sun Woo-Yees charts with the diseases which are in the medical books excavated in MA WANG TEI(馬王堆), "YOUNG COO(靈樞)" and "SO MUN(素問)", and to investigate their interactions. The results obtained are as follows : 1. JOE(疽) which is made in stomach and bowels is not found at the medical books excavated in MA WANG TUI(馬王堆), "YOUNG COO(靈樞)" and "SO MUN(素問)". JOE(疽) which is made on the breast is similar to JOE(疽) which is made on the chest of "YOUNG COO(靈樞)". 2. It is said in Sun Woo-Yee(淳于意)'s charts that mental depression blocks up the circulation of Kl(氣), and it is the same viewpoint of "YOUNG COO(靈樞)"and "SO MUN(素問)". 3. The POONG GYUL(風厥) and the YOUL GYUL(熱厥) that are found in the Sun Woo-Yee(淳于意)'s charts is similar to those of "SO MUN(素問)", but different from those of "YOUNG COO(靈樞)". 4. It is regarded that YONG SAN(涌疝) in the Sun Woo-Yee(淳于意)'s charts is similar to the COONG SAN(퇴산) in "SO MUN(素問)", KI SAN(氣疝) in the Sun Woo-Yee(淳于意)'s charts is related to the TUI SAN(癡疝) of the medical books excavated in MA WANG TUI(馬王堆), "YOUNG COO(靈樞)" and "SO MUN(素問)", MO SAN(牡疝) in the Sun Woo-Yee(淳于意)'s charts is considered PE SAN(肺疝) and PE POONG SAN(肺風疝) in "SO MUN(素問)", but more and deeper study is required. In the change of the terms ; from TUI SAN(癡疝) to TUI SAN(퇴산), from PYUN SAN(偏疝) to HO SAN(狐疝), it can be guessed that the terms changed, as new doctrines were introduced and reorganiged with the development of the medical theory. 5. POONG BI in the Sun Woo-Yee(淳于意)'s charts is not found in "YOUNG COO(靈樞)", but it is similar to DAN FEVER(단열) in "SO MUN(素問)". It is regareded that PE SO DAN(폐소단) in the Sun Woo-Yee(淳于意)'s charts is the same as that of "YOUNG COO(靈樞)". 6. DONG PUNG in Sun Woo-Yee(淳于意)'s charts is not found in "YOUNG COO(靈樞)"and "SO MUN(素問)", but it seems like DONG SOEL(洞泄) in "YOUNG COO(靈樞)". It is regareded that the DONC PUNG(동풍) in the Sun Woo-Yee(淳于意)'s charts was at first changed into DONG SOEL(洞泄), and later differentiated into DOHG SOEL(洞泄) and SON SOEL. 7. In the Sun Woo-Yee(淳于意)'s charts, the treatment of the decayed tooth had the classification of the right and left, seeing cauterization with moxa on SU YANG MYOUNG MAEK(手陽明脈), it is considered that the tooth was decayed in the lower right. region. A tooth was related to QI MAEK(齒脈) and BI YANG MYUNG MAEK(臂陽明脈) in the early stage, but gradually was related to not only SU YANG MYUNG MAEK(手陽明脈) but also JOK YANG MYUNG MAEK(足陽明脈), JOK SO YIN MAEK(足少陰脈), JOK TAE YIN MAEK(足太陰脈), and in regards to the tooth and KYUNG MAEK(經脈), "YOUNG COO(靈樞)" emphasised the course of the KYUNG MAEK(經脈), "SO MUN(素問)" emphasised the attachment of the five elements. 8. In regards to BI(痺), the importance of the five elements theory given in the Sun Woo-Yee(淳于意)'s charts is similar to that of "SO MUN(素問)", and "YOUNG COO(靈樞)" and the medical books excavated in MA WANG TUI(馬王堆) give the same importance to the Kyung MAEK(經脈) theory. 9. The explanation of the irregular menstruation in the Sun Woo-Yee(淳于意)'s charts was fundamentally similar to that of "SO MUN(素問)", but it shows the another theory that can not found in "SO MUN(素問)".
