We analyzed the chirp sound and behavior of Teleogryllus emma with observation system, which was consisted of computer, ccd-camera and microphone. Computational methods of wavelet transformation and Self-Organizing Maps (SOM) were utilized to characterized the chirp sound of insect species for automatic counting in this study. Wavelets were initially applied to feature extraction of the chirp sound. Wavelet coefficients were accordingly calculated based on the basis function (e.g., Morlet). The obtained coefficients were subsequently provided to count number of chirps in each song. Sound structure of insect specimens consisted with long chirp and short chirp and the patterns of song were grouped by frequency of long chirp and short chirp. The song patterns of insect specimens were divided by Self-Organizing Map (SOM) that was used number of chirp as input data. Application of computational methods to automatic detection of chirp sound was further discussed for obtaining objective assessment in behavior science.

The side weir is a structure that is installed to maintain uniform overflow discharge and reduce or distribute the peak flow in downstream at flood. The facility has been widely used in reducing the peak flow of flood when increasing the runoff in proportion to the development of watershed. To estimate more accurately the outflow over a sharp crested side weir, it is necessary to analyze the flow characteristics over side weir and to estimate the discharge coefficient in the weir equation. The purpose of this study is to suggest the suitable length of side weir and to propose equations for the discharge coefficients of side weir in off-line detention basin by means of hydraulic model experiments with the variations of upstream Froude number in the main channel and length of side weir. Experimental results show that the discharge coefficients depend on the upstream Froude number in the main channel and the ideal ratio of side weir length to main channel width was found to be more than 6.

The role and importance of groundwater are increased with the deficiency of surface water and contamination of river on the development and management of water resources. But in recent, imprudent development gave the negative impact on the aspect of the quantity and quality of groundwater. For example, the excessive pumping leads to exhaution of groundwater, and waste materials bring about contamination of groundwater. On the contaminant problem, the groundwater flow is the important media of pollutant transport and its phase is different hydraulic conductivity. Therefore, 2-D numerical model using FEM is developed. To verify this numerical model, it is compared with Theis's analytical solution for unsteady groundwater flow and existed model(used FDM). In this study, numerical model(used FEM) gives good agreement between analytical solution and existed model(used FDM). In this numerical simulation, homogeneous aquifer is supposed to use coarse sand, heterogeneous aquifer is supposed to consist of coarse sand and coarse gravel, and coarse sand and silt. The result of numerical simulation generally shows good agreements with real groundwater flow through homogeneous and heterogeneous aquifer.

In this paper, the vertical Hall device which is sensitive to the magnetic fields parallel to the surface of the chip, is fabricated and characterized. The Hall voltage was ±0.2[mV] in the range of ±100[Gauss]. The current-related Magnetic sensitivity(S_(H)) was about 55[V/AT]. With an increased I_(sup), the offset voltage was also increased. Alternating Current(AC) driving system was used to process the amplification of Hall voltage and the reduction of offset and noise by the AC driving of the vertical Hall device. When the AC driving system was operated, the output of the Hall voltage was ±74.0 [mV] in the low magnetic field ranges of ±100 [Gauss], The magnetic fields resolution was 0.74[mV/Gauss].

Objectives : This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). Methods : The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. Results : The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-.98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However,the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. Conclusion : The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.

The purpose of this study was to investigate the patterns of the health related variables, and physical characteristics and physical fitness of the elderly people in order to provide a exercise program. The data about the health related variables were collected through the personal interview, and the data about physical charateristics and physical fitness (height, weight, % body fat, blood pressure, pulse rate, grip stength, trunk flexion, side step test, 2 min, harvard step test) of 373 elderly people living Seoul and kyungkee area were collected. The conclusions of this study can be summarized as follow; 1. The test results about smoking, drinking, sleeping and self-evaluation of health revealed that the elderly people have self-confidence about their health. 2. Not many elderly people participate the proper exercise program even though they recognize the need of exercise. 3. The results showed that the elderly people do not pay much attention to the intensity of the exercise. 4. Muscle strength training for leg and the lower back and cardio-vascular endurance training was recommended to reduce the risk of varius problems caused by aging. 5. A exercise program was suggested for the elderly people.

Objectives : We examined the effects of INM 176 (K-l107) compared with placebo on the cognitive functions of 92 old aged subjects with cognitive impairment. Methods : This was a prospective, 12 week, double-blind, Placebo-controlled clinical trial. The elderly who achieved a score of less than 25 points on the K-MMSE or showed a high risk of Alzheimer's disease from the 7-Minute Neurocognitive Screening Battery were considered to have objective impairment and were selected as subjects for this study. The subjects were randomized to placebo or INM 176 group. The outcome measures were from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog), the Instrumental Activities ofDaily Living (IADL) and the Korean Geriatric Depression Scale (KGDS) and two kinds of computerized priming tests. After setting the total error score in the Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog) as the repeated measurement factor, an analysis of variance of the combined factor design was done between the placebo and INM 176 group. Results : The interaction effect of time (pre- and post-trial) and group (placebo and INM 176 group) was significant in the analysis of the ADAS-cog's total error score. The INM 176 group's total error score in the ADAS-cog decreased significantly (p<0.01), whereas the placebo group showed a slight increase. The mean changes in IADL and GDS from baseline scores favored in the INM 176 group than in the placebo group. Outcome changes ofADAS-cog, IADL, KGDS scores during the 12 week clinical trail ofINM 176 and placebo demonstrated favorable responses in the INM176 administered group. Conclusions : This is a preliminary clinical trial result of INM176 as a memory pill. Based on these results, INM176 may be a candidate molecule for the improvement of cognitive functions, including memory, Further clinical trial should demonstrate its efficacy.

In order to evaluate the effect of poloxamer 407 content on the dissolution profiles of pellets, diltiazem HCl (DTL) core pellets were prepared with poloxamer 407 (50∼90% w/w, with lactose as filler) using an extruder and a spheronizer. Any possible interaction between the drug and excipients was evaluated using DSC, IR and TLC. Dissolution tests were performed using USP basket method. In addition, scanning electron micrograph was performed to examine the surface roughness and cross sections. The release of DTL from the core pellets was decreased with increasing poloxamer 407 content. Cracks appeared on the surface of the core pellets with increasing the poloxamer 407 content, which may play a role on the retardation of the release of DTL from core pellets. There was no any significant interaction between the drug and excipients employed to prepare the core pellets.
