Objectives : The aim of this paper is to examine the mechanisms of spontaneous sweating and night sweating, their relationship and how the explanations of their mechanisms have changed over the course of time, through examination of past discussions on spontaneous sweating and night sweating. Methods : Contents in classical medical texts that mention the mechanisms of spontaneous sweating and night sweating among search results from databases such as the Siku Quanshu were analyzed, followed by examination of each of their mechanisms, and their relationship with each other. Results & Conclusions : The cause of night sweating before the 『Danxixinfa』 was seen to be caused by yang deficiency in relation to problems of Exterior Qi and the theory of 'Heart governs perspiration', as the focus was on the phenomenon of sweating. However, it seems that yin deficiency came to be seen as playing a more fundamental role in the process of determining the root cause of night sweating. Moreover, Zhu Danxi's emphasis on nurturing yin, the composition of Dangguiliuhuangtang, and the development of the fire-heat pathology since the Jin Yuan period added to this shift in perspective. Night sweating from Shanghan could be seen as a sign of the already damaged Exterior Qi becoming more deficient while the pathogenic qi is in the half-exterior-half-interior zone, or as the pathogenic qi which entered with the Exterior Qi unsettling yin, or as a result of heat that is produced in the struggle between healthy qi and pathogenic qi that happens when Exterior Qi enters. Night sweating from miscellaneous disease could be seen as a sign of a deficient exterior that resulted from excessive entering of the Exterior Qi during yin deficiency, or resulting from relatively excessive Exterior Qi to deficient yin, producing heat that leads to sweating. If yin is not cultivated during the night but rather consumed leading to deficiency of Exterior Qi which also needs to be cultivated during night time, it could result in sweating.

While Internet-based distance learning has proliferated, its educational effectiveness remains controversial. As such, investigation into the problems of Internet-based distance learning is important and fundamental for an assessment of its educational effectiveness. In this study, problems of Internet-based distance learning are grouped into four categories, environmental problems, student problems, course design problems and operational problems. Based on survey data from 606 distance learning participants, perceptional and relative seriousness of problems are analysed. The results indicate that perceptional seriousness of all the problems is not statistically important. However, the findings indicate that the relative seriousness of self willingness among student problems and cheating within operational problems is most remarkable. In contrast, the relative seriousness of traditionally recognized problems such as H/W availability and network speed among environmental problems is least remarkable. An analysis of demographic differences such as sex, employment and age in terms of seriousness of problem is also performed. The results reveal the existence of statistically significant differences according to sex, employment, and age difference with regard to seriousness of problems.

The purpose of this study is to analyze how a well-structured cognitive reflection journal can affect a learner's metacognition and learning achievement in the area of Engineering Education. The objects of this study were 143 students in total (experimental group: 52, control group: 91) who are taking the 'Fundamental Semiconductor Engineering' course in the Engineering Department at D college in the metropolitan area. For his particular study, we undertook three steps as follows. First, we verified that the two groups of students were equal in areas of metacognition and learning achievement. Second, the experimental group was asked to keep writing the well-structured reflection journal for four weeks and the control group was not. Third, we evaluated the metacognition and learning achievement. This study used a questionnaire to measure metacognition by Sperling(2002) in a Korean translation as well as a well-structured cognitive reflection journal. As a result, we found that the well-structured cognitive reflection journal affects learners positively in the sense of metacognition ability, continuity as well as learning achievement.

This study focuses on finding out engineering characteristics of asphalt concrete mixtures using mineral fillers with recycled waste lime, which is a by-product in the Soda Ash(Na2CO3) production course. The materials tested in this study were made with 25%, 50%, 75% and 100% of mixing ratio based on the conventional mineral filler ratio to analyze the recycle possibility of the waste lime. The asphalt concrete mixtures with recycled waste lime and hydrated lime, and conventional asphalt concrete mixtures were evaluated through their fundamental engineering properties such as Marshall stability, indirect tensile strength, resilient modulus, permanent deformation characteristics, moisture susceptibility and fatigue resistance. The results indicate that the application of recycled waste lime as mineral filler improves the permanent deformation characteristics, stiffness and fatigue endurance of asphalt concrete mixtures at the wide range of temperatures. It is also found that the mixtures with recycled waste lime show higher resistance against stripping than conventional asphalt concrete mixtures. It is concluded from various test results that the waste lime can be used as mineral fillers and especially can greatly improve resistance to permanent deformation of asphalt concrete mixtures at high temperatures.

In order to investigate the meanings and bases of transforming theories of diseases(病傳論), several relevant theories were collected from medical books since . The outside-to-inside changing process(pyoree jeon) was the fundamental pattern in febrile diseases regardless of slang han and wen bing after Han dynasty. But in case of numb disease the three exogenous pathogenic factors of wind, cold and dampness got into each viscera through five tissues like skin, vessesl, flesh, tendons, bones respectively. It was called corresponding changing process(sanghap jeon) here. The pathogenic changing process(byungsa jeon) had complicated details to explain pathologic processes, but could give useful informations on evaluating relative strength of pathogens and tendency ahead. The changing process of diseases of internal injuries were explained in case of emotional distress which is outbroken abruptly didn't follow regular order of viscera-emotion relations. So it was named random changing process(bulcha jeon) after 's usage. And marasmus and asthenic disease followed top-to-down or down-to-top changing process(sangha jeon) based on . There are many types of changing process of diseases between viscera and viscera or viscera and bowels like generation changing process, restriction changing process, changing process between couple, changing process of mutual transmission based on attributions of each element by the theory of 5 phases(五行論). And changing process to a neighbor doesn't have any special relations within two organs but has anatomical contiguity and physiological continuity between them. The transforming theories of diseases bring forth useful understanding on comings and goings of pathogenic factors and tendency and prognosis of disease, so they are needed to be taught in the course of pathology class.

The main purpose of this study is to prepare an outline for developing the Contents Systems that achieve self-study systems to make the students adopt themselves into new study atmosphere and maximize the result of study on technical college in Electric-Electronic field. Questionnaire posed to analyze the demand of teaching materials to the students, and professors and also to find characteristics of students in technical college. The SPSSWIN/PC+ statistics Package was used to assay the collected answers. And simple frequency with percentage, average, and standard deviation were calculated to check the entire trend and actual state of each question. The primary outcomes of this study are as follows i) The students in the technical college prefer self-directed learning to lecturer-oriented teaching. ii) It is difficult to offer the technical college students normal education systems since the students?interest and motivation towards study are very low. iii) The lack of capability of foreign language and basic mathematics are considered as obstacles for many students technical college to study. iv) The professors in technical college still depend on traditional method to teach the students without organized research of the intellectual levels and attitude the students. v) Teaching materials in currently use are not appropriated to induce the motivation and interest of study from the students. Also, the teaching materials in use now were discovered not to have enough originality, practical application, andwere text based. Therefore, the improvement of the existing teaching materials was demanded while the fundamental ability to study of general students is declining. Consequently, it is necessary to introduce new teaching materials which are simple, easy, and organized to offer the studen ts study desire and interest.

The 'Program outcomes and assessment' is an important criterion evaluating of engineering education in accreditation of engineering education. ABEEK prescribes program outcomes which are the basic capabilities in the application of the fundamental knowledge and practical tools of the engineering field. Also ABEEK asks to prove that all programs are constructed a proper educational curriculum and are satisfied program outcomes and CQI. Therefore program outcomes must satisfy both two key points. First, as a quality control aspect, engineering programs must prove that graduates of accredited programs can perform twelve capabilities. Second, as a continuous quality improvement aspect, accredited programs have to upgrade a level of engineering educational quality. Consequently the purpose of study is to introduce a new model for CQI and QC systems, implementing strategies as an actualizing of program outcomes.

Using the protein A-gold complex, the mvoabrillogenesis and actin localization of cultured myoblast were invastisated. In the superstructural changes of mvogenic cell during differentiation, pectoral myoblasts contained large nucleus and numerous ribosomes but no myofibrils during the first 24 hr of cultures. Mvoblast initiated to differentiate at 3-day of culture contained the primitive myofibrillar structure. At 96 hr of culture, the mvofibrillar structure showed reletively discernable Z band but pools defined A, H and M bands. The feature of sarcomeric structure showed more defined form at cultur 5 day. In the aspect of actin localization, actin wvas diffusely detected throughout the cytoplasm of myogenic cell and nucleus during the proliferating stage. At 72 hr of culture, with the appearantc oi primitive mvofibrils, gold particles were observed in surrounding of myofibrils but still presented in overall of cytoplasm, especially in the surface and lumen of endoplasmic reticulum. With the gradual increase of culture time, local distribution of actin was readily detected within cytoplasm. In the 5-day specimen of cultures, gold particles precisely indicate the sites of actin localifation within the sarcomere. These results indicate the time of onset of myofibrill appearance and the biosynthetic and incorporation pathway of actin molecules into sarcomeric structure during myofibrillogenesis. Thus, in the present study, the first mvoabrillar structure was detected at culture 3 day, and the initiation of assembly into a typical sarcmeric structure was observed at culture 5 day. It seems, however, that the course of events on myofibrillogenesis of cultured myoblasts can be changed with great dependence of culture conditions including the number and groluth rate of mononucleated mvoblasts after seeding although the fundamental process shows identical appearances.
