Objective : To review the method, parameters, system of electrogastrography and to study its oriental medical application. Method : We investigate the research results through internet search engines such as Pubmed, China National Knowledge Infrastructure. Conclusion : Electrogastrography is believed to be of great use to the verification of treatment effect of herbal medicine that is used in internal medicine and neuropsychiatry, along with the objectification and quantification of diagnosis of oriental medicine related to gastric peristalsis and balance of autonomic nervous system. I would therefore like to conclude that there should be continued study and active application of electrogastrography in the wide variety of oriental medicine.

Criminology is not a science yet in the sense that the word is used to describe the hard science. It is due to the fact that sociologists have dominated in the study of crime and criminals. Thus, future criminological studies should adopt an interdisciplinary approach including such disciplines as biology, psychology, sociology, and so on. The interdisciplinary approach needs to pursue a general theory by systematizing the achievements from various disciplines in the explanation of criminal behavior. The current study also discussed several issues which are conducive to the scientific study of criminal behavior.

In this study, a direct detection system for triazine derivative herbicides was developed using the photosynthetic reaction center (RC) from the purple bacterium, Rhodobacter sphaeroides, and surface plasmon resonance (SPR) apparatus. The histidine-tagged RCs were immobilized on an SPR gold chip using nickel-nitrilotriacetic acid groups as a binder for one of the triazine herbicide, atrazine. The SPR responses were proportional to the sample concentrations of atrazine in the range 0.1-1 $\mu\textrm{g}$/mL. The sensitivity of the direct detection of atrazine using the RC-assembled sensor chip was higher than that using the antibody-immobilized chip. The other types of herbicides, DCMU or MCPP, were not detected with such high sensitivity. The results indicated the high binding selectivity of the RC complex.

AcrR, the toxic-compounds-response regulator, regulates motility in microorganisms, presumably to escape from toxic environments. In this study, the genome-wide target genes of AcrR were investigated in a ΔacrR mutant strain by microarray analysis. In the absence of AcrR, the transcription of most flagella/motility genes was highly increased. In addition, flagella formation was increased in this mutant strain. Motility assays revealed that AcrR modulates swimming motility, but not swarming.

The paper studies on the cooperation between the humanities & social sciences and natural science & technology in 1990's. The article showed policy alternatives about the crisis of humanities & social sciences. That was science wars and we heard that was announced by Sokal affair. In this article, the author inquired into the Korean research policy's crisis and presented the policy alternatives about the crisis of humanities & social sciences and natural science & technology in various ways. In the concrete, the policy alternatives are cultural critique of technology and science and science & development of domain about interdisciplinary studies at the humanities & social science and natural science & technology. In conclusion, First, the author showed the appraisal and institutionalization of interdisciplinary studies. Second, the researcher proposed few policy alternatives and developmental area of interdisciplinary studies between the humanities & social sciences and natural science & technology.

Recent studies proved turbulent flow properties in high-rise building models differ from those in low-rise building models by comparing turbulent statistics. Although it is important to understand the flow characteristics within and above high-rise building models in the study of urban environment, it is still unknown and under investigation. For this reason, we performed wind tunnel experiment using Particle Image Velocimetry (PIV) to investigate and identify the turbulent flow properties and characteristic flow patterns in high-rise building models. In particular, we focus on instantaneous flow field near the canopy and extracted flow field when homogeneous flow field were observed. As a result, six characteristic flow patterns were identified and the relationship between these flow patterns and turbulent organized structure were shown.

In this study, the object is a development on uroflowmetry system to detect a voiding symptom conveniently in home or hospital. The hardware was composed of mechanism and system circuit part, the software was divided into firmware and PC program part. The following experiment was performed to evaluate an ability of classification and fitness. First, the following parameters was calculated in each flow curve pattern. The parameters are MFR, AFR, VOL, VT, FT, and TMF. A significant difference among parameters was examined through a statistical analysis for extracted parameters between normal and abnormal group. In the next work, the following experimentation was performed to classify the voiding symptom. Analysis of congregate rate was examined to find out classification possibility about each symptom of BPH, voiding difficulty, detrusor failure and hyperreflexia, unstable bladder. The uroflow data with the above symptom was divided into normal and abnormal group using fuzzy classifier. and that was performed appending the other group again. Fuzzy classification result using MFR and AFR was superior by 89.6 % more than grouping evaluation including VOL.

Background and Purpose : The Purpose of this study is to review the recent achievements on SDPTG and suggest SDPTG studies. Methods : The study papers related with SDPTC, published in foreign countries and Korea up to the present, were collected by internet search & journal. And then the collected papers were classified and summarized. Results and Conclusion : SDPTG provides informations of arterial elasticity and stiffness. thus, SDPTG could contribute to development of pulse wave diagnosis of oriental medicine.

Background and Purpose: There was seldom study about method that diagnose 8 Constitution beside method of pulse diagnosis in 8 Constitution Medicine. Objectives: This study is to make out check list for 8 Constitution Medicine Diagnosis Expert System Development used CBR(Case based Reasoning). Methods: Review of literatures about special quality element of 8 Constitution and supplement learning advice of 8 Constitution Medicine Experts constructed knowledge base. And then, knowledge base divided through AHP(Analytic Hierarchy Process), and made out check list with this. Results: Knowledge base based on special quality element of 8 Constitution was divided by 5 greate classification and 25 bisection kind, and check list consisted of 251 item was made out through this. Conclusion: Based on this research, cases necessary to make 8 Constitution Medicine Diagnosis Expert System can be gathered through check list, and further study for 8 Constitution Medicine Diagnosis Expert System Development used CBR(Case based Reasoning) is needed to supplement this research.

This paper suggests a method to refine a massive collective intelligence data, and visualize with multilevel sentiment network, in order to understand information in an intuitive and semantic way. For this study, we first calculated a frequency of sentiment words from each movie review. Second, we designed a Heatmap visualization to effectively discover the main emotions on each online movie review. Third, we formed a Sentiment-Movie Network combining the MDS Map and Social Network in order to fix the movie network topology, while creating a network graph to enable the clustering of similar nodes. Finally, we evaluated our progress to verify if it is actually helpful to improve user cognition for multilevel analysis experience compared to the existing network system, thus concluded that our method provides improved user experience in terms of cognition, being appropriate as an alternative method for semantic understanding.
