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.

In order to investigate to develop the new dosage form of the traditional herbal medicine which have been used for the treatment of disease in oriental medicine, we conducted a survey on 217 patients who visited oriental hospital in Kyung Hee University Medical Centre during one month since October 2003. They were given questionnaires to answer and results of this study were as the following: 1. About 45% patients visited in oriental hospital believed that oriental medicine was better remedy than modern medicine. 2. Most of patients felt that the oriental medical expenses were expensive. 3. About 60% patients preferred the modernized dosage form such as extract powder and granule, etc. rather than medicinal herbs in package. 4. Most of patients hope that decoction of medicinal herbs in package would change the advanced dosage forms such as tablet, capsule and extract powder, Because patients suffered from inconvenience of making a decoction, unhandy, unwieldy and keeping. 5. About 60% patients pointed out that merits of advanced dosage forms of medicinal herbs were convience to take and handy, etc.. However, they had an Intension that there were some difference of efficacy between decoction and modernized dosage forms of oriental medicine. Because of several defects such as unusual flavor and smell, incompatible food, large volume with amount, inconvenience of carrying and decocting oriental herbal medicines, most of patients would expect the development of the advanced dosage forms of them. In summary, this study show that it was needed to develop the new dosage forms of oriental herbal medicine on the basis of scientific research and economical cost of medical expenses.

In this study, We carried out the preparing standardization and regulation of processed Glycyrrhizae Radix(PGR) which have been widely used in oriental medicines. Glycyrrhizae Radix(GR) have been generally prepared by the stir-frying, or mix-frying with honey for purpose of decreasing sweetness and augmenting vitality. Firstly, we tried to standardize PGR prepared by the stir-frying. We purchased 14 kinds of PGR and non-processed GR(NPGR) at oriental physician's offices and oriental pharmacies on a nation scale, respectively. The amounts of dry on loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, glycyrrhizin(GL), glycyrrhetic acid(GA) and liquiritin(LQ) of them were examined. The amounts of dray on loss, GL and LQ in commercial PGRs showed remarkable decrease, while GA showed increase as compared with NPGR. In order to standardize preparing method of PGR, the effect of heating time on physico-chemical parameters and biological activities were examined. Physico-chemical parameters such as dry on loss, extract amount, GL and LQ contents in PGRs showed decrease, however, GA was increased with heating time as compared with NPGR. Also, GA obtained form heat-treated GR, was found as an artifact in PGRs. PGR was more effective than NPGR in vitro test of DPPH scavenging effect and TBA-Rs reducing effect. PGR and NPGR showed potent hepatoprotective effect on CCl_(1)-intoxicated rats. Especially, PGR prepared by 80 min of heating was the most effective. Considering these results, the optimal condition for PGR preparation was 150℃ for 80min.

박성용,최남기,양규호 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.3

교정 치료시 비발치에 의한 치료는 종종 치료 결과가 안정적이지 못하고 환자의 안모가 심미적이지 못한 단점이 있어, 조화로운 안모와 골격 , 치아의 안정성을 위해 발치에 의한 교정치료를 선택하는 경우가 많다. 교정 치료시 바람직한 목적의 달성을 위해 소구치, 대구치 혹은 때때로 절치나 견치를 발치하기로 결정할 수 있는데, 제1소구치 발치는 대개 I급 구치부관계의 악궁내 총생을 해결하고 치아의 안정성과 바람직한 안모를 얻기 위해 시행한다. 그러나, 안모의 함몰이나 수직 고경 상실등의 부작용이 나타날 수 있다. 이에 반해 제2대구치 발치는 치료 후 안모의 풍만감이나 수직 고경이 상실되지 않고 측두하악관절에 덜 위해하며, 폐쇄해야할 공간이 없고 전치부 및 구치부의 총생을 동시에 해결하며 발치된 제2대구치를 제3대구치로 대치시키는 장점이 있다. 또한 치료 후 재발의 관점에서도 제1소구치 발치보다 우수한 것으로 알려져 있다. 본 증례는 I급 구치부관계를 가지는 총생 환아에서 제2대구치 발치를 통해 교합과 안모에서 바람직한 결과를 얻었기에 이에 보고하는 바이다. Department of Pediatric Dentistry, College of Dentistry, chonnam University Since Non-Extraction treatment in some orthodontic case shows unstable result and unfavorable profile, extraction is selected as inevitable treatment option for the harmonious profile, facial skeleton, and the stable dentition on both arches. For the achievement of proper goal, premolars, molars, sometimes incisors or canines are selected to be extracted. The first Premolar is usually extracted for relieving the crowded dentition with which the molar relations are class I to gain stable dentition and proper profile, but often results in the depression of profile or the loss of vertical dimension. On the contrary, the extracton of the second molar helps maintaining the fullness of profile and the vertical dimension, prevents additional space closural procedures which often make the procedures complicated, relieves both anterior and posterior crowding, and substitutes the extraction fossae for newly erupting 3rd molars. From the point of recurrence , the second molar extraction procedure, therefore, is more beneficial. This cases showed the good results of second molar extraction procedures in the patients with class I crowding.

김남재,진성민,최혁재,주수만,송보완,김종우 한국병원약사회 2002 병원약사회지 Vol.19 No.4

The influence of single and repeated oral pretreatment of CHUNG-HYUL-DAN(CHD). a widely used Korean traditional herbal medicines prescribed for hypertension and hyperlipidemia, on the pharmacokinetics and pharmacodynamics of a calcium channel blocker, nicardipine after oral administration of nicardipine was investigated in rats. The single pretreatment of CHD significantly increased area under the plasma concentration-time curve(AUC_(0-8h), but did not influence the time to reach the maximum peak plasma concentration(T_(max)), the maximum peak plasma concentration(C_(max)), terminal elimination half-life(t_(1/2) or the elimination rate constant(λ) for nicardipine. And, C_(max) and AUC_(0-8h) for nicardipine were significantly increased by with 1-week repeated pretreatment with CHD, but the other parameters were not significantly different from those of control. Also, the extent of the lowering effect of nicardipine on blood pressure in rats was significantly increased after oral administration of nicardipine with single and repeated oral pretreatment with CHD. These results indicated that single and 1-week repeated oral pretreatment with CHD should inhibit the metabolism of nicardipine in rats.

Deposition samples were collected in wet gauge and dry gauge containers at downtown of Iksan city, located southwest of the Korean peninsula, from April 20 to May 1, 2004. The volume of 30-50㎖ deionized water was added for wet gauge before sampling, but dry gauge was installed in the dry state with no deionized water adding. These samples were collected twice a day during daytime and nighttime and were analyzed for anions(Cl^(-), NO^(3-), SO₄^(2-)) and cations (NH₄^(+), Na^(+), K^(+), Mg^(2+), Ca^(2+)) using ion chromatography. Data quality was checked by the data obtained from re-injection of standard solution, Dionex cross check standard solutions, and random several deposition samples, and measured data was estimated to be reliable. Considering the deposition sample volume, the sampling time, the surface area of sampling container, and the ion concentration measured, the deposition amounts were calculated in mg/㎡/day. The sum of ion dry deposition amounts for dry gauge and wet gauge was 9.1±6.7 mg/㎡/day and 26.5±9.1 mg/㎡/day, respectively. A significant increase in deposition amount during rainfall days and Asian yellow dust period was observed for both wet gauge and dry gauge, especially during rainfall days having no difference of deposition amount between in wet gauge and in dry gauge. The mean deposition of all ions measured in this study were higher in wet gauge than in dry gauge because of the surface difference of the sampling container. The mean deposition amount of NH₄^(+), SO₄^(2-), and NO^(3-) in wet gauge were found to be about 27.6 times, 5.5 times, and 3.4 times higher. than that in dry gauge, while the rest of the chemical species were equal or a little higher in wet gauge than in dry gauge. Dominant species in dry gauge were SO₄^(2-) and Ca^(2+), accounting for 14.7% and 47.3% of the total ion dry deposition, whereas those in wet gauge were SO₄^(2-) and NH₄^(+), accounting for 27.7% and 27.1% of the total ion dry deposition, respectively.

Background and Objectives : Chronic suppurative otitis media is one of the frequent diseases in otolaryngologic field. It is important to choose of antibiotics in the management of infectious disease. But the organisms in infections have been changed and resistance to antibiotics has been grown as the development of antibiotics has been achieved. And so it has been necessary to recognize the changes of organisms and resistance in antibiotics. Our study was performed to identify the pathogens isolated from discharges in chronic otitis media and evaluate the antibiotic agents, to recognize the change of to resistance to·antibiotic agents and to use the appropriate anitiotics. Materials and Methods : Retrospectively, authors reviewed the backeriologic study of 114 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Soonchunhyang University in Seoul from Nov. 1996 to Oct. 1999 and analyzed 101 strains and its sensitivity test to various antibiotics. Result : In 93 cases in which pathogenic organism was isolated, single infection was 85 cases(91.4%) and mixed infection was 8 cases(8.6%). The most frequent pathogenic organism was Staphylococcus aureus(59.4%), Pseudomonas aeruginosa(13.9%), Providencia(4.8%), Alcaligenes(3.0%) and Streptococcus pneumoniae(2.9%) were the next. Methicilline-Resistance Staphylococcus aureus was 34 cases(57.6%) of Staphylococcus aureus. Staphylococcus aureus was sensitive to Vancomycin(96.7%), Trimethoprim-Sulfamethoxazole (57.6%), Cefuroxime(42.4%) and Ciprofloxacin(40.7%) but resistant to Penicillin(94.9%). Pseudomonas aeruginosa was sentitive Amikacin(100%), Ciprofloxacin(100%) and Gentamicin(67%). Conclusion : As MRSA recently was wide spread in community accquired infection as well as nosocomial infection, we must consider strict control of MRSA.
