This study examined the knowledge and understanding of integrative medicine in Korea, specifically conflicts between western and oriental medicine within Parallel (Dual) health care systems. Qualitative methodology using grounded theory guided semi-structured, in-depth interviews with Western Medical Doctors (W.M.D., n = 6), Oriental Medical Doctors (O.M.D., n = 5) and Traditional Chinese Medicine Practitioners (T.C.M.P., n = 4). Thematic analysis was used to determine broad themes from the interviews. 15 professionals (W.M.D. (40%), O.M.D. (33%), T.C.M.P. (27%), 10 males (67%) and 5 females (33%), mean age 45) were interviewed, recorded, and transcribed. Thematic analysis revealed three key themes: systematic conflicts, integration and future directions. Subthemes of systematic conflicts included: credibility of Oriental Medicine, commercial imperatives, maintaining social standing of O.M.D., professional qualifications and lack structures supporting collaborative practice. Integration subthemes included lack of academic linkage and clarity for appropriate triage, opposing medical paradigms and limited social imperative. Future directions should include: social justification, guarantee of oriental medicine legitimacy, role of government and understanding of scientific evidence. To successfully integrate dual medical systems there is a need to address differences in social-environmental factors and perceptions of scientific understanding, as well as developing strong academic links in clinical practice.

Purpose: This study standardizes the position and direction of devices based on general user expectations and stereotypes. Population stereotypes are cognitive structures that contain the perceiver's knowledge, beliefs, and expectations about human groups. In this paper, the stereotypes that people typically expect when manipulating 'cylindrical key-in-knob locks' and 'lever-type water faucet handles' were investigated and data regarding their expectations were collected. Methods: Two sets of 600 participants, between 13 and over 60 years old, were recruited for the experiment. Each group was evenly subdivided into six age groups. Each participant was presented with cylindrical door locks mounted on a miniature door and actual lever-type water faucet handles mounted on a mockup sink. Results: If the cylindrical lock was positioned 'vertically,' 59.2% of the participants expected the device to be locked, and if the lever type faucet handle was positioned 'up,' 63.0% of the participants expected the device to be turned on. Thus, daily-use devices should be designed consistent with user expectations of operation. There was a significant difference between genders for manipulating the faucet handle between up and down. Conclusion: A more general stereotype may be defined by repetitive measurements under the same test conditions with fixed time intervals, as well as accounting for people with cognitive problems.

Recent research on steel moment-resisting connection between steel beams and concrete filled steel tubes has shown that there are considerable advantages to be obtained by anchoring the connection to the concrete infill within the tube using anchors in blind bolts. In the research reported here, extensive experimental tests and numerical analyses have been performed to study the anchorage behaviour of cogged deformed reinforcing bars within concrete filled circular steel tubes. This data in essential knowledge for the design of the steel connections that use anchored blind bolts, both for strength and stiffness. A series of pull-out tests were conducted using steel tubes with different diameter to thickness ratios under monotonic and cyclic loading. Both hoop strains and longitudinal strains in the tubes were measured together with applied load and slip. Various lead-in lengths before the bend and length of tailed extension after the bend were examined. These dimensions were limited by the dimensions of the steel tube and did not meet the requirements for "standard" cogs as specified in concrete standards such as AS 3600 and ACI 318. Nevertheless, all of the tested specimens failed by bar fracture outside the steel tubes. A comprehensive 3D Finite Element model was developed to simulate the pull-out tests. The FE model took into account material nonlinearities, deformations in reinforcing bars and interactions between different surfaces. The FE results were found to be in good agreement with experimental results. This model was then used to conduct parametric studies to investigate the influence of the confinement provided by the steel tube on the infilled concrete.

The purpose of this research was to investigate the effects of content and formal schema on reading comprehension. Five hundred fiftynine subjects from high school were assigned to one of the following levels and treatment conditions : (1) Higher level & Schema Activation, (2) Higher level & Non-schema Activation, (3) Lower level & Schema Activation, and (4) Lower level & Non-schema Activation. To evaluate the effects of schema activation. two experiments were conducted : one was related to the content schema and the other to the formal schema. To evaluate the effects of content schema, three different types of tests were conducted : (1) cloze test, (2) guessing the meanings of nonsense words, and (3) immediate recall test. To evaluate the effects of formal schema instruction, four kinds of tests were conducted : (1) sorting the sentences according to the importance, (2) identifying the signal words, (3) immediate recall test, and (4) identifying the specific information. For content schema condition, results indicated that the subjects given the titles or pictures before reading in "Content Schema Activation" treatment had better grades than those of the other treatment in all types of tests. regardless of their levels. Schema activation helped the subjects to increase the cognitive predictability of missing words and to participate in the tasks more actively with risk-taking. And it was also shown that good readers tend to process the words meaningfully, while poor readers tend to process the words phonetically or morphologically. Formal schema activation through teaching the text organization also had a significant influence on three types of tests: sorting the sentences according to the importance, identifying the signal words, and immediate recall test, but not on identifying the specific information. The implications from this study can be briefly noted as follows : (l) In teaching reading, the student's background knowledge should be activated as a pre-reading activity. (2) In reading, it is more important to emphasize the student's schema than the features of the text. (3) Various educational interventions should be introduced, especially for the lower level students. (4) Teaching text structures can be a powerful method for the top-down processing strategy.

Secondary school environmental education is offered mostly in extra-curricular activities, not included in the school curriculum. Therefore, drawing out its curriculum has been left to teachers' discretion. Teachers' beliefs in EE have much more influence on the selection of content of EE than any other psychological factors. It follows that the reality of school EE depends on what teachers believes about EE and which content of EE they select according to their beliefs. This study is to research the realities of the secondary school EE: examine teachers' beliefs about EE and analyse environmental views in their environment-related programs; examine whether teachers' programs reflect their beliefs and environmental views; identify the factors which teachers inhibit teachers from their expression of these beliefs. To identify what perspective was reflected to these programs, this study employs environmentalism. Environmentalism can be classified into 3 categories: environmental management; deep ecology; social ecology. Data were gathered by means of in-depth interviews with five teachers. To show teachers' beliefs clearly, the analysis of the data was conducted on the basis of 5 categories: 'ecological sensitivity', 'value education', 'behaviors', 'issues', 'perception of a cause of environmental problems, related to social structures'. These belifs reflect deep ecological perspective and social ecology. But these perspectives did not accord with those in programs. Most EE programs included only the deep ecological perspective. They didn't reflect their beliefs that students should perceive the cause of environmental problems in the social structure. The factors which teachers find as inhibiting or supporting their expression of these beliefs were analysed as following: (1) EE requests the change of curriculum and methods of instruction; (2) teachers should acquire 'environmental consciousness' and environmentrelated knowledge; (3) programs requests an administrative and financial support.

Reflecting the fact that there are increasing number of old high-story apartment structures in urban area, it is expected that the demand of blasting demolition will increase in the near future. It is of great important to make up for the insufficient empirical knowledge in blasting demolition through priori method such as computer simulation. Computer simulation of the blasting demolition involves complicated process. In the past domestic researches, two-dimensional bonded particle model was used to examine the overall demolition behavior of a five-story simple structure. It was observed that the two-dimensional simulation did not properly simulate the collapsing behavior of a structure mainly due to the reduced degree of freedom. In this study, three-dimensional simulation was tried. It consumed a great amount of calculation time, which limited the extent of the study. A few parameters, such as delay times, amount of charge at each hole, ball properties, were modified in order to check oui; their effect on the collapsing behavior. The differences were observed as expected but the collapsing behavior did not exactly coincide with the test blasting with a scaled model.

A 10-year-old Korean native female Jin-do dog revealed two growing subcutaneous masses measuring 7.0 ${\times}$ 7.0 ${\times}$ 2.5 cm and 5.0 ${\times}$ 4.0 ${\times}$ 2.0 cm in the left shoulder and lower part of chest, respectively. Grossly tumor masses were well-circumscribed and exhibited ulcerated surface and purulent exudate on the cut surface. Histologically tumor masses were characterized by cystic structures some of which were fused together. Although the cells of cyst wall differentiated to those similar to infundibulum, isthmus, inferior segment of hair follicles, respectively, the most cyst wall consisted of cells similar to infundibulum The luminal content of cysts depended on the cells of cysts; infundibulum-like cyst contained lamellar keratin, isthmus-like cyst was amorphous keratin, and inferior segment-like cyst had shadow cells. From these results, these tumor masses were diagnosed as multiple trichoepithelioma. To our knowledge, this is the first report of canine multiple trichoepthelioma in a dog in Korea.

The objectives of this study are to evaluate the reliability of an existing nonlinear analysis program for predicting the inelastic behavior of reinforced concrete frame with seismic details and to observe the redistribution of the internal forces, which can not be easily measured by an experiment. In order to carry out this task, the nonlinear analysis program of IDARC 2D(3) was run on a 2-bay, 2-story moment-resisting reinforced concrete plane frame with seismic details. (1) The effort to obtain the results of the analysis similar to those of experiment was made by determining the appropriate values of model parameters. The comparison of the analysis results with those of experiment and the observation of the distribution of internal forces obtained through nonlinear analysis points to the following conclusions. (1) The overall relationship between lateral load and lateral displacement given by the analysis is similar to that of experiment. However, the values of initial stiffness and the amount of energy dissipation in the initial displacement steps given by the analysis show larger values than those of experiment. (2) The analysis provided detailed information on the distribution and redistribution of internal forces and proved useful in elucidating the crack pattern, the sequence of the occurrence of plastic hinges, and the failure or yielding mechanism for the whole structure. (3) In spite of the similarity in overall behavior of analysis and experiment, there exists a significant discrepancy in some local behaviors. Furthermore, the hysteresis in the relationship between moment and curvature in some column ends have shown sudden deteriorations in strength, which can not be interpreted satisfactorily at the present time. Therefore, it is necessary to develop a better analytical model to fill this knowledge gap.

Alkali-activated binder (AAB) is recently being considered as a sustainable alternative to portland cement (PC) due to its low carbon dioxide emission and diversion of industrial wastes and by-products such as fly ash and slag from landfills. In order to comprehend the behavior of AAB, detailed knowledge on relations between microstructure and mechanical properties are important. To address the issue, a new approach to characterize hardened pastes of AAB containing fly ash as well as those containing fly ash and slag was adopted using scanning electron microscopy (SEM) and energy dispersive X-ray spectra microanalyses. The volume stoichiometries of the alkali activation reactions were used to estimate the quantities of the sodium aluminosilicate (N-A-S-H) and calcium silicate hydrate (CSH) produced by these reactions. The 3D plots of Si/Al, Na/Al and Ca/Si atom ratios given by the microanalyses were compared with the estimated quantities of CSH(S) to successfully determine the unique chemical compositions of the N-A-S-H and CSH(S) for ten different AAB at three different curing temperatures using a constrained nonlinear least squares optimization formulation by general algebraic modeling system. The results show that the theoretical and experimental quantities of N-A-S-H and CSH(S) were in close agreement with each other. The $R^2$ values were 0.99 for both alkali-activated fly ash and alkali-activated slag binders.

Landscape zones have been designated as aesthetic old town districts across a wide range of Nakakyo-Ku and Shimokyo-Ku, city center of Kyoto, Japan. In these districts in which traditional structures and new buildings coexist, regulations of restriction on acts such as new building's heights, shapes, materials, and colors are carried out according to local governmental landscape ordinance based on Scenic Conservation Act. And yet, minimal fulfillment of the regulations according to different designer's subjective interpretation and principle of economy is rather creating abnormal shapes not harmonized with the traditional landscape. Thus, this study aims to extract combinations between form elements of middle and high rise apartment facade that affects 'harmony' and 'mismatch' in the districts by clarifying the social rules commonly implied based on intuitive judgments (sensibility evaluation) in which human experiential knowledge is involved. As research methods, the study first analyzes the form elements of the facade through a field survey, sets up a standard model through tasks of classification and segmentation and draws computer graphic images with 99 different patterns based on it. Based on these images, this study carries out sensibility evaluation and analyzes experimental data applying the rough set theory. As a result of the analysis, the combinations of form elements that affect harmony or mismatch act greatly when the colors and shapes of the pillars, positions and the patterns of the use of the first floor are combined.
