On this research. The method of space analysis(Space syntax) is used to investigate the relation between composition and configuration in the houses of four modern architects. Space analysis represent that the houses permutate the morphological properties of depth and rings to embed domestic fuctions within the hoe and to interface household memgers. Two of the house are judged to be well composite but banal: The other appear more inventive in relation compositinal principles to space configuration, to create a measure of subtlety and richness in life style which is lacking in the examples where form is manipulated in the abstract. On this research. It is discoverd that Knowledge of both the internal laws of form and the social logic of space is required to generate the practical conjunction of formal rigour with fuctional ease which we recognise in the houses of architects.

With respect to the tensile strength of volcanic rocks in Jeju Island, a comparative study was conducted using the existing research results and the test results performed in this study. In addition, the characteristics and effectiveness of the cohesion and internal friction angle estimated from the Brazilian tensile strength and unconfined compressive strength of Jeju volcanic rocks were investigated. As results, the Brazilian tensile strength of Jeju volcanic rocks was closely related to absorption, and decreased exponentially as the absorption increased. It was confirmed that the internal friction angle was closely related to the ratio of unconfined compressive strength to Brazilian tensile strength (σ_c / σ_t), and increased logarithmically as the ratio of σ_c / σ_t increased. In addition, the ratios of σ_c / σ_t of Jeju volcanic rocks were in the range of 5~20 depending on the magnitude of internal friction angle. In the case of cohesion, it was closely related to the absorption and Brazilian tensile strength. The cohesion exponentially decreased as the absorption increased, such as the relation between the Brazilian tensile strength and absorption. It was confirmed that there was a linear relation between the cohesion and Brazilian tensile strength.

Objectives : The purpose of this study is to find out the relation between the height of intercrestal line, and HIVD(Herniated Intervertebral Disc)of Lumbar spine. Methods : We investigated 445 cases (208 male, 237 female) of patients who were diagnosed as HIVD of L-spine at either L4/5 or L5/S1 level. We analysed the relation between the height of intercrestal line and the level of HIVD. Results : 1. Among 445 cases, the level of intercrestal line with HIVD of L-spine at the specific location was different between male and female. In male, the intercrestal line is more likely to be located at L4 level, while in female more likely to be located at L5 level. 2. Among 445 cases, L5/S1 HIVD patients(272, 61.1%) were more than L4/5 HIVD patients(173, 38.9%). At L4 body area, L4/5 HIVD patients were more than L5/S1 HIVD patients, however, at L4/5 intervertebral area and L5 body area, L5/S1 HIVD patients were more than L4/5 HIVD patients. (p<0.01) 3. When the line is located at higher level, HIVD of L-spine tends to be occurred at L4/5 level. Contrastly, when the line is located at lower level, HIVD of L-spine tends to be occurred at L5/S1 level. (p<0.01) Conclusions : High intercrestal line leads to L4/5 HIVD, while low intercrestal line leads to L5/S1 HIVD. Possibly, it is caused by different length and thickness of the iliolumbar ligament.

The wind-induced transient response of internal pressure following the creation of a sudden dominant opening during the occurrence of high external pressure, in low-rise residential and industrial buildings was numerically investigated. The values of the ill-defined parameters namely the flow contraction coefficient, loss coefficient and the effective slug length were calibrated by matching the analytical response with the computational fluid dynamics predictions. The effect of a sudden i.e., "instantaneously created" windward opening in the Texas Technical University (TTU) test building envelope was studied for two different envelope flexibility-leakage combinations namely: (1) a quasi-statically flexible and non-porous envelope and (2) a quasi-statically flexible and porous envelope. The responses forced by creating the openings at different time leads/lags with respect to the occurrence of the peak external pressure showed that for cases where the openings are created in close temporal proximity to the peak pressure, the transient overshoot values of internal pressure could be higher than the peak values of internal pressure in the pre-sequent or subsequent resonant response. In addition, the influence of time taken for opening creation on the level of overshoot was also investigated for the TTU building for the two different envelope characteristics. Non-dimensional overshoot factors are presented for a variety of cavity volume-opening area combinations for (1) buildings with rigid/quasi-statically flexible non-porous envelope, and (2) buildings with rigid/quasi-statically flexible and porous envelope (representing most low rise residential and industrial buildings). While the factors appear slightly on the high side due to conservative assumptions made in the analysis, a careful consideration regarding the implication of the timing and magnitude of such overshoots during strong gusts, in relation to the steady state internal pressure response in cyclonic regions, is warranted.

This study was aimed to investigate the electrolytes and its relationship with acute stroke patients in each stroke type by case-control study. 217 patients with first-ever acute stroke within 2 weeks as the case group(Cases), 146 people without four major risk factors(hypertension, diabetes mellitus, hyperlipidema and ischemic heart disease) as the healthy control group(Normals), and 160 people as the general control group(Controls) were recruited at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital from july 2005 to march 2007 for this case-control study. We analyzed the odds ratio of electrolytes in binary logistic analysis and evaluated each stroke type and general characteristics such as age, sex etc. The level of sodium(Na+) and potassium(K+) were significantly lower in LAA, SVO type of ischemic stroke and hemorrhagic stroke. But the level of chloride(Cl-) had no significant relation with stroke occurance. In this study we demonstrated that low sodium(Na+) and potassium(K+) have an influence on stoke occurance than chloride(Cl-). And we think that the electrolytes must be considered in risk factors of ischemic stroke in Korean and more prospective studies are needed.

This paper aims to examine the role of mediating effect of trust to leaders on the relation between internal marketing and customer orientation. A survey was conducted to examine the responses of 570 employees. Reliability, confirmatory factor analysis and structural equal modeling were used for results. The following are the summary of hypothesis test. First, internal marketing has positive effect on customer orientation. Second, internal marketing has positive effect on employee's trust to leaders. Third, trust to leaders has positive effect on customer orientation. Fourth, the mediating effects of trust to leaders partially mediated the relationships among empowerment, training, reward, internal communication and customer orientation and fully mediated the relationship between management support and customer orientation. Therefore, the results of this study have many theoretical and practical implications.

Objectives: The purpose of this study was to evaluate the relation between intentionally induced internal stress and cyclic fatigue failure of .06 taper ProFile. Materials and Methods: Length 25 mm, .06 taper ProFile (Dentsply Maillefer), and size 20, 25, 30, 35 and 40 were used in this study. To give the internal stress, the rotary NiTi files were put into the .02 taper, Endo-Training-Bloc (Dentsply Maillefer) until auto-stop by torque controlled motor. Rotary NiTi files were grouped by the number of induced internal stress and randomly distributed among one control group and three experimental groups (n = 10, Stress 0 [control], Stress 1, Stress 2 and Stress 3). For cyclic fatigue measurement, time for separation of the rotary NiTi files was recorded. The fractured surfaces were observed by field emission scanning electron microscope (FE-SEM, SU-70, Hitachi). The time for separation was statistically analyzed using two-way ANOVA and post-hoc Scheffe test at 95% level. Results: In .06 taper ProFile size 20, 25, 30, 35 and 40, there were statistically significant difference on time for separation between control group and the other groups (p < 0.05). Conclusion: In the limitation of this study, cyclic fatigue failure of .06 taper ProFile is influenced by internal stress accumulated in the files.
