  • Objectives : Based on the entries on each medicinal's 'specification' and the phrase '所以然' in the Shennong Bencao Baizhonglu, this paper aims to examine Xu Dachun's understanding of herbal medicinals. Methods : One hundred medicinals from the text were sorted into eight categories: Qi, flavor, color, form, quality, nature and characteristic, time of growth, and producer, then examined. Results : 1. Medicinals related to Qi were aromatic and pungent and warm. 2. Medicinals related to flavor were explained according to the Five Flavors' nature in terms of the thing and its functions theory. 3. Medicinals related to color were explained in relation to the Five Colors, whose interpretations were rather erratic. 4. Medicinals related to form were explained as it being possible to figure out their effects based on each medicinal's shape and form. 5. Medicinals related to quality were those that were used to manage dryness and dampness using their dry or wet qualities. 6. Medicinals related to nature and characteristics needed to be understood in their originality to grasp their unique abilities. 7. Both producer and time of growth were closely related to each medicinal's efficacy. Conclusions : Understanding of the application of medicinals in the Shennong Bencaojing through continuous examination into each medicinal's 'specification' and 'its reasoning', together with their clinical application, will allow for learners to build an understanding of herbal medicinals.

  • This paper suggests a simple approach to determining the screw characteristics for a three0dimensional flow in a channel with a finite aspect ratio(ratio of a width to a depth, W/H) by introducing a Total Shape Factor($F_t$) to correct a two-dimensional flow analysis for a channel with an infinite aspect ratio. In the present study, the Total Shape Factor($F_t$) was defined as a ratio of a net flow rate obtained by the three-dimensional analysis to that by the two-dimensional analysis. In the proposed approach, the quantity, $ \frac{{\partial}F_t}{\partial(H/W)}$ turns out to be almost constant and to play an important role in understanding the effects of the flights. Therefore, $ \frac{{\partial}F_t}{\partial(H/W)}$ are extensively reported in this paper in terms of several dimensionless parameters. This simple approach with such database will be very useful for extruder designers to predict the screw characteristics.

  • Generally, a vertical rolling process is used to achieve extensive width reduction in hot strip mill. However, it is impossible to avoid the defects such as dog-bone and edge-seam defect. The sizing press process has been developed in response to the defects mentioned above. Especially, this study is carried out to investigate the deformation of slab by two-step sizing press. The deformation behavior of slab in the sizing press process is more favorable than that in conventional vertical rolling edger. The FE-simulation is applied to predict the deformation behavior of the slab. In this paper, the several causes of the asymmetrical deformation are mentioned for the purpose of understanding of the anvil shape. Load, dog-bone and edge-seam defect are discussed in width sizing process considering the anvil shape. And to reduce the problems generated at rougher mill just after sizing press, these are studied in this paper. The deformation behavior of slabs and optimum anvil shape are obtained by rigid-plastic finite element analyses and neural network.

  • The purpose of this article is to investigate the forms and styles of pond at private housing in terms of diachronically influencing characteristics in the Choson Dynasty. From various literatures and records, we have selected 73 cases of pond. We have analyzed the types of pond based on square type, squared type with islets, and modified types and found the following results: 1) Chronically, shapes of pond had been chanced from the three prototypes into their features of deducting side or edge, adding a triangular or trapezoid shape, and installing more islets, and replaced their figures with gradually progressive from side having a straight lined shape to a curved one. 2) As for characteristics of arranging ponds, we found three patterns of arrangement - the juxtaposition with a similar shape of pond, juxtaposition with a different shape of pond, and the juxtaposition with a pond having different topological level in the light of the relation with a stream and a pond. We can conclude the two changed patterns of ponds at private residence in Choson Dynasty that the one had been transformed shapes of pond with sides of pond, and the others had been transformed juxtaposition with either a stream or a natural stream. From this research we can find an important implications in understanding patterns and types of garden in the Choson Dynasty from exploratory approach and in the future the relationship between topographical characteristics of private residence and Confucian ideas, and shapes of pond is needed to be examined in explanatory manner.

  • A questionnaire was administered to 850 middle school students in Jinju city and Hamyang province to asses their body shape preferences. Their mean current BMI(body mass index, Kg/㎡) in males(19.23±2.77) was higher than that in females(18.61±2.59). On the other hand, significant differences in BMI were not found between areas. The perceived desired weights for their current height were about+0.22kg(males) and -4.32kg(females) of their actual weights. In spite of the average weight group, many wished to lose weight because of their tendency to perceive themselves as overweight, especially among rural females. Their ideal body shape as perceived by them were 'normal' in males and 'a bit thin' in females, independent of the areas. As for the 'contentment' regarding their current weight and health, the most satisfied group in males were estimated average weight and slightly overweight group, respectively. While, the most satisfied group in females were estimated slightly underweight and overweight group, respectively. Their extreme slim-body preference might have its root in the lack of proper understanding of what the 'standard' body weight was.

  • A new technique to mitigate irregular buildings with soil structure interaction (SSI) effect subjected to critical seismic waves is presented. The L-shape in plan irregular building for various reasons was selected, subjected to seismic a load which is a big problem for structural design especially without separation gap. The L-shape in plan building with different dimensions was chosen to study, with different rectangularity ratios and various soil kinds, to show the effect of the irregular building on the seismic response. A 3D building subjected to critical earthquake was analyzed by structural analysis program (SAP2000) fixed and with SSI (three types of soils were analyzed, soft, medium and hard soils) to find their effect on top displacement, base shear, and base torsion. The straining actions were appointed and the treatment of the effect of irregular shape under critical earthquake was made by using tuned mass damper (TMD) with different configurations with SSI and without. The study improve the success of using TMDs to mitigate the effect of critical earthquake on irregular building for both cases of study as fixed base and raft foundation (SSI) with different TMDs parameters and configurations. Torsion occurs when the L-shape in plan building subjected to earthquake which may be caused harmful damage. TMDs parameters which give the most effective efficiency in the earthquake duration must be defined, that will mitigate these effects. The parameters of TMDs were studied with structure for different rectangularity ratios and soil types, with different TMD configurations. Nonlinear time history analysis is carried out by SAP2000 with El Centro earthquake wave. The numerical results of the parametric study help in understanding the seismic behavior of L-shape in plan building with TMDs mitigation system.

  • Currently on the school education site, various multimedia contents are used to effectively deliver knowledge to the students and increase interest in class. The majority of the multimedia contents currently used in classes are composed of visual and auditory information. This paper intends to maximize actuality and immersion in the content by adding olfactory information to the existing visual and auditory data. Tangible contents were developed based on the details of aromatic plants learned in the fifth grade of elementary school. The shape and explanation of the aromatic plants are displayed with visual and auditory information, and an aroma spraying application is used to allow the students to smell the aromatic plants. After conducting the class using the developed contents, the students' satisfaction of the class, as well as their overall academic understanding, were investigated. Upon doing so, it was discovered that the students' academic understanding and satisfaction increased in comparison to classes comprised of only visual and auditory contents.

  • Objectives This paper aims to understand the emotional-biological pathogenesis of eating disorders, and translate the understanding into new brain directed treatments. Methods The first part of the review sets the eating behavior into the context of what is now understood about the central control of appetite and molecular biology. The second part of the review sees how emotion relates to the brain circuit involving eating disorders. Results In general, patients with anorexia nervosa restricting type were less sensitive to reward, whereas patients with bulimia nervosa and anorexia nervosa binge purging type were more sensitive to it. The emotional life of people with eating disorders centers on food, weight, and shape. The abnormalities in social and emotional functioning both precede and persist outside of eating disorders. Conclusions Research into understanding the biological framework of the brain in eating disorders suggests that abnormalities may exist in emotional and information processing. This aspect can be translated into novel brain-directed treatments, particularly in anorexia nervosa.

  • WHAT we teach, and HOW students experience it, are the primary factors that shape students' understanding and beliefs of what mathematics is all about. Further, students pick up their sense of mathematics from their experience with it. We have seen the results of the approach to "break the subject into pieces and make students master it bit by bit. As an alternative, we strive to create a teaching environment in which students are DOING mathematics and thereby engender selected aspects of "mathematical culture" in the classroom. The vehicle for doing this is the so-called Japanese Open-ended approach to teaching mathematics. We will discuss three aspects of the open-ended approach - process open, end product open, formulating problems open - and the associated approach to assessing learning.
