Die vorliegende Arbeit macht die $Theaterst{\ddot{u}}cke$ von Park seit Mitte der 2000er Jahre zu ihrem Forschungsgegenstand. Park stellt nun mannigfaltige Verfahrensweise von dramaturgischer Technik und $Theater{\ddot{a}}sthetik$ zur $Verf{\ddot{u}}gung$, damit er den Zuschauer auf die gesamten $Zust{\ddot{a}}nde$ der $zeitgen{\ddot{o}}ssischen$ Gesellschaft aufmerksam macht und auch die Teilnahme daran beeinflusst. Indessen benutzt Park die Theorie des Lachens im breiten Spektrum. So verbindet er das Lachen jeweils mit der Komik des Grotesken, des Paradoxons und der Satire, um dessen Effekt zu maximalisieren. Und die $Theaterst{\ddot{u}}cke$ von Park mobilisieren die $Performativit{\ddot{a}}t$ aufgrund der Aisthetik, damit sie die Grenzen jener semiotischen Interpretation ${\ddot{u}}berwinden$, die auf der sprachzentrierten $Repr{\ddot{a}}sentation$ basiert. Infolgedessen wird jene Kommunikation aufgrund der sinnlichen Wahrnehmung aktiv $eingef{\ddot{u}}hrt$, die sich anhand des Austausches von Energie und $Atmosph{\ddot{a}}re$ zwischen $B{\ddot{u}}hne$ und Zuschauerraum vollzieht. Darum zeigt die $Theater{\ddot{a}}sthetik$ von Park jene mehreren gemischten Merkmale, die die traditionelle ${\ddot{A}}sthetik$ der $Repr{\ddot{a}}sentation$ mit der Verfahrensweise der ${\ddot{A}}sthetik$ der Postmoderne verbinden. Indem Park mit Hilfe von der mannigfaltigen Verfahrensweise von Dramaturgie und $Theater{\ddot{a}}sthetik$ zu einem experimentellen Versuch zu Theaterformen gelangt, treten in seiner Theaterkunst eben das $zeitgen{\ddot{o}}ssische$ verdinglichte Gesellschaftsbild und zugleich die $Negativit{\ddot{a}}t$ als eine $k{\ddot{u}}nstlerische$ Kritik daran in Erscheinung. Vor dieser Folie versucht die vorliegende Arbeit nicht nur die Dramturgie und $Theater{\ddot{a}}sthetik$ von Park zu erforschen, sondern auch das daraus resultierende $zeitgen{\ddot{o}}ssische$ Gesellschaftsbild wissenschaftlich zu $er{\ddot{o}}rtern$.

The electrocardiogram (ECG) signal is a good indicator for early diagnosis of heart abnormalities. The ECG signal has a different reference normal signal for each person. And it requires lots of data to diagnosis. In this paper, we propose an adaptive OpenCL-based FPGA-GPU hybrid-layer platform to efficiently accelerate ECG signal diagnosis. As a result of diagnosing 19870 number of ECG signals of MIT-BIH arrhythmia database on the platform, the FPGA accelerator takes 1.15s, that the execution time was reduced by 89.94% and the power consumption was reduced by 84.0% compared to the software execution. The GPU accelerator takes 1.87s, that the execution time was reduced by 83.56% and the power consumption was reduced by 62.3% compared to the software execution. Although the proposed FPGA-GPU hybrid platform has a slower diagnostic speed than the FPGA accelerator, it can operate a flexible algorithm according to the situation by using the GPU.

The aim of this study is to predict the potential for bid-rigging among public construction bidders and develop preventive and responsive measures. By employing the Fraud Triangle Theory (FTT), which considers the factors of opportunity, pressure, and rationalization, we analyze and explore the bid-rigging potential among construction industry professionals. A survey is conducted among General and specialized construction firms to validate the FTT research model and predict individual bid-rigging tendencies. The results indicate that higher levels of pressure, greater opportunities, and stronger rationalization increase the likelihood of individual bid-rigging. Moreover, more opportunities and stronger rationalization also raise the potential for bid-rigging by others. Understanding these dynamics enhances our knowledge and contributes to the development of policies aimed at preventing bid-rigging.

This study examined the germination characteristics by collecting fruits and pretreatment of the diaspore from April 2014 to June 2015 to investigate the diaspore characteristics, seed dispersion, and seed germination characteristics of two myrmecochorous spring ephemerals (MCSE): -Jeffersonia dubia (Jb) and Corydalis remota (Cr)-. The diaspore of Jb was about 5mm-long yellow-dark brown, oblong seeds with the attached amorphous white elaiosome. The mean weights of diaspore, seed, and elaiosome were 15.86mg, 13.46mg, and 2.40mg, respectively, and the elaiosome ratio was 15.13%. The diaspore of Cr was about 1.2mm diameter and glossy black ovoid seeds with the attached white spatula-shaped elaiosome. The mean weights of diaspore, seed, and elaisome were 2.58mg, 2.05mg, and 0.53mg, respectively, and the elaiosome ratio was 20.54%. Camponotus niponensis and Formica japonica transported the diaspore of Jb while Formica japonica and Lasius japonicus transported the diaspore of Cr. The germination percentage of Jb seeds was statistically significant and had the significance level of 1% with the pretreatment and date of sowing. However, it was independent of attachment of elaiosome. The mean germination percentages of Jb seeds was 65.0% during sowing on June 20, 17.5% during sowing on August 19, and 0% during sowing on October 20. The germination percentage of Cr was statistically significant and had the significance level of 5% and 1% with the attachment of elaisome and date of sowing, respectively. The mean germination rates were 54.17% and 35.0% in the non-treatment section and the treatment section with elaisome detached, respectively. The mean germination percentages of Cr seeds was 75.0% during sowing on June 20, 53.75% during sowing on August 19, and 5.0% during sowing on October 20. Considering the fact that the ants transported the diaspores to the ant house when the fruits of MCSE were ripened and dropped the seeds, the direct seeding right after collecting may be most suitable to the characteristics of the evolution of these plant species and may be the best method to obtain the highest germination percentages. Since the ants distribute their seeds, the MCSE produces and attaches the elaiosome to the seed to maintain the symbiotic relationship with ants. The ants then transport the seed to the ant house where the environment is controlled for suitable temperature and humidity, and then the MCSE succeeds in germination after the embryo grows sufficiently in the next spring.

To separate and concentrate mucilage from yam(Dioscorea batatas DECNE), yam was dried, microparticulated using impact mill and air-classified at different air classifying wheel speed(ACWS) in classifier. As ACWS increased from 5,000 rpm to 22,500 rpm, the contents of dietary fiber, protein and lipid of air classified microparticles(ACM) increased remarkably. Especially the ACM with ACWS over 15,000 rpm showed 36.41% dietary fiber and 16.66% protein. The dietary fiber and protein components were concentrated to $2.5{\sim}9.0$ times as compared with whole yam powder. Concomitantly the non-fibrous carbohydrate decreased from 88.31% to 16.84. The damaged starch(%), WSI and WAI of ACM of ACWS over 15,000 rpm were $1.5{\sim}3.0$ times higher than those of ACM under ACWS 15,000 rpm. The apparent viscosity of ACM was 0.0800 Pa s over ACWS 15,000 rpm and 0.0080 Pa s under ACWS 15,000 rpm. Judging from viscosity of ACM, the mucilage component of yam was concentrated to 10 times. In conclusion, the optimum process to separate and concentrate the mucilage from yam consisted of the microparticulation to $5{\sim}30{\mu}m$ and the air-classification at ACWS over 15,000 rpm.

Abnormal illness behavior in patients with somatoform disorders were known formed by their traditional disease concepts and somatization-prone socio-cultural factors. The authors evaluated the characteristics of abnormal illness behavior in patients with somatoform disorders(who had somatization) by using abnormal illness behavior questionnaire. Methods : 29 somatoform disorders(SD) and 57 disease controls were compared by clinical characteristics, severity of pain, state anxiety(by Spielberger's State & Trait Anxiety Inventory), depression(by Beck's Depression Inventory) and level of psychosocial stess(by DSM-III-R). The illness behavior was measured by illness Behavior Questionnaire(IBQ). Results SD group had longer period of somatic symptoms with less severity in pain. The degree of anxiety and depression were higher in SB compared with controls. However, the degree of psychosocial stress was almost same between both groups. In IBQ, SD showed higher scores in general hypochondriasis, disease conviction, and affective disturbance subscales compared to control group. Conclusion: High disease conviction and hypochondriacal nature revealed by IBQ seemed to be a role in making somatization by way of somatic focusing and hypervigilance. And those tended to lead patients visit hospital frequently and report various somatic complaints. Evaluating abnormal illness behavior in somatoform disorders would be not only helpful in understanding the natures of somatoform disorders but also useful differentiating SD with other psychiatric conditions.

Recently, fusion camera systems that consist of depth sensors and color cameras have been widely developed with the advent of a new type of sensor, time-of-flight (TOF) depth sensor. The physical limitation of depth sensors usually generates low resolution images compared to corresponding color images. Therefore, the pre-processing module, such as camera calibration, three dimensional warping, and hole filling, is necessary to generate the high resolution depth map that is placed in the image plane of the color image. However, the result of the pre-processing step is usually inaccurate due to errors from the camera calibration and the depth measurement. Therefore, in this paper, we present a depth map upsampling method robust these errors. First, the confidence of the measured depth value is estimated by the interrelation between the color image and the pre-upsampled depth map. Then, the detailed depth map can be generated by the modified kernel regression method which exclude depth values having low confidence. Our proposed algorithm guarantees the high quality result in the presence of the camera calibration errors. Experimental comparison with other data fusion techniques shows the superiority of our proposed method.

The leading surgical method for correcting the misalignment of the varus and valgus in the knee joint is the high tibial osteotomy (HTO). In the opening wedge HTO (OWHTO), there is no concern about damaging the peroneal nerve on the lateral tibia of the proximal fibula. OWHTO has been the preferred choice, as the opening of the correction angle can be modulated during the operation. The correction of the varus and valgus on the coronal plane are performed adroitly. Nevertheless, there have been numerous reports of unintended changes in the medial tibial plateau and posterior slope angle (PSA). The authors have developed an HTO method using computer-assisted surgery with the aim of addressing the abovementioned problems from an engineer's perspective. CT images of the high tibia were reconstructed three-dimensionally, and a virtual osteotomy was performed on a computer. In addition, this study recommends a surgical method that does not cause changes in the PSA after OWHTO. The results of the study are expected to suggest a clear relationship between the anteromedial cortex oblique angle of each patient and the PSA, and an optimal PSA selection method for individuals.

The cryIB, truncated cryIB$[cryIB({\alpha})]$, cryIA(b), and cytA genes, encoding 135-, 89-, 131-, and 27-kDa proteins, respectively, from Bacillus thuringiensis were cloned into a shuttle vector pBES and expressed in E. coli and Bacillus species. The morphology and solubility in alkaline buffer of the insecticidal crystal proteins were investigated. Transformation of intact cells of E. coli and Bacillus species was achieved by electroporation. High field strength of 11.0 kV/cm and resistance of 129 ohms were required for efficient transformation of E. coli strains and 4.5 kV/cm and 48 ohms for Bacillus species. Strains of recombinant E. coli and Bacillus species produced the insecticidal crystal proteins and accumulated as the same bipyramidal and irregular structures as those of CryIB and IA(b) and CytA of B. thuringiensls, respectively. The insecticidal crystal proteins accumulated in recombinant E. coli wire smaller in size than those in recombinant Bacillus species. The solubility in alkaline buffer of the insecticidal crystal proteins of recombinant E. coli increased gradually as the pH increased, whereas in the case of Bacillus species the solubility increased gradually as the pH increased up to 9 and then the solubility increased greatly up to two times higher than that of E. coli proteins.
