Objectives : Sa-am Acupucture(舍岩鍼法), Taeguk Acupucture(太極鍼法), and 8 Constitution-Acupuncture(八體質鍼法) are largely used acupuncture therapies which utilize Yin and Yang, The Five Elements, Interpromoting and Counteracting Relation(相生 相克 關係). We are here to compare and study each acupuncture methods in order to understand their fundamental principle and theory. Conclusion : 1. When prescribing Herb to patients, we can use the Differentiation of Syndromes method(辨證論治). As there is Constitutional Medicine prescription(四象醫學處方) using constitutional Large & Small Relation of Jang and Bu organs(臟腑大小 關係), in acupuncture treatment we can use the Differentiation of Syndromes method of Sa-am acupucture, applying constitutional Large & Small feature of Jang and Bu organs(臟腑大小) in Taeguk Acupucture and 8 Constitution Acupuncture we can derive a suitable prescriptions. 2. Taeguk Acupucture and 8 Constitution Acupuncture is an acupunture method created upon the constitutional theory. Taeguk Acupucture lacks a theory and has problems with its practical use. 8 Constitution-Acupuncture has a theory, thus it can give us the chance to make derived diverse prescriptions for each diseases. 3. Sa-am Acupucture uses exclusively Manual technique(手技法), breathing Posa method(呼吸補瀉法), YoungSu Posa method(迎隨補瀉法) and also retaining method(留鍼法). Taeguk Acupunctune is directed related with WonBang Posa method(圓方補瀉法), twirling method(撚鍼法) and uses retaining method. 8 Constitution-Acupuncture works only with YoungSu Posa method and also One-insertion method(單刺法). 4. If we apply The Five Elements of five Su points and Interpromoting and Counteracting Relation(相生 相克 關係), we can control discords between Jang and Bu organs. Sa-am Acupucture, Taeguk Acupture and 8 Constitution Acupuncture which use five Su points can make better results in Jang and Bu organs disease. 5. Sa-am Acupunture needs diverse applications of Organ picture theory(臟象論), Pathogenesis theory(病機學說) and an proper prescription studies by Differentiation of Syndromes(辨證). Taeguk Acupuncture and 8 Constitution Acupuncture has a organized prescription methods by constitutional Large & Small relation of Jang and Bu organs(臟腑大小), thus we need to focus on objectification in constitutional differentiation.

The structures and complexation energies of penta-O-alkylated 1b and penta-O-tert-butyl ester 1e of p-tert-butylcalix[5]arene and their simplified structures (2b and 2e) toward a series of alkyl ammonium guests have been calculated by a semi-empirical AM1 method. For AM1 calculations, complexation efficiencies of the simplified host 2e are very similar to the values of host 1e. The complexes of simplified host 2e with alkyl ammonium ions also have been optimized by ab initio HF/6-31G method. The calculated complexation efficiencies for 2e by ab initio method have been found to be bigger in magnitude than the values obtained by AM1 calculations for linear alkyl ammonium guests. Calculation results show that all of the calix[5]aryl derivatives investigated in this study have much better complexation ability toward ammonium cation without alkyl group compared with other alkyl ammonium guests. Ab initio calculations also well duplicate the molecular discriminating behaviors of calix[5]arene derivative 2e between butyl ammonium ions: $n-BuNH_3^+\;>\;iso-BuNH_3^+\;>\;sec-BuNH_3^+\;>\;tert-BuNH_3^+$.

Susceptibility or resistance of the Bordetella bronchiseptica was determined by using the broth microdilution method. Each Bordetella bronchiseptica was tested fur sutraceptluility with 7 different antimicrobial agents.4 high prevalence of resistance (greater than 80 %) was found when Bordetella bronchiseptica was tested with amikacin (AK), ciprofloxacin ILrJl gentamlcin IGAgf, kanamycin (Kbf) and tobramycin (TM). However, the Bordetella bronchiseptica were sensitive to chloramphenicol (CP) and tetracycline (TC). Three different combination of drug resistance were observed : AM-CF-GM-TM (1 strain), AM-CF-GM- KM-TM (45 strains), and AM-CF-GM-KM-TM-CP (3 strains). The MICs against Bordetella bronchiseptica were 0.13 to >2.00 for TC, 4 to >648 for CP, 8 to >128 for CF 16 to >256 for GM, 16 to >256 for TM, 32 to >256 for KM and 64 to 256 for AM.

Objectives : This study was undertaken in order to establish the composite principles of fomulas through the of Sa-am acupuncture therapy and the theory of sovereign, minister, assistant and courier. Methods : We analyzed the formula construction of Sa-am acupuncture therapy, and applied the theory of sovereign, minister, assistant and courier that was referred to in the preface of "Essential Rhymes on Acupuncture and Moxibustion by Master Sa-am" to the analysis of formula construction. Results & Conclusions : 1. Sa-am acupuncture therapy was acupuncture and moxibustion method that inherited and developed progress contents of Chinese traditional acupuncture and moxibustion. 2. The theory of sovereign, minister, assistant and courier was based on the idea that acupuncture and herbal medicine had the same origins. 3. Formula constructions of Sa-am acupuncture therapy were formed complicatedly, but reflected the theory of sovereign, minister, assistant and courier. 4. The supplementing acupuncture point that is Chunbu-point in other merdian became Sovereign, the draining acupuncture point that is Chunbu-point in other merdian became Minister, and the supplementing and draining acupuncture points in same merdian became Assistant and Courier that mean leading merdian points.

The purposes of this study were: 1) to show the item difficulty hierarchy of walking/moving construct of the International Classification of Functioning, Disability and Health-Activity Measure (ICF-AM), 2) to evaluate the item-level psychometrics for model fit, 3) to describe the relevant physical activity defined by level of activity intensity expressed as Metabolic Equivalent of Tasks (MET), and 4) to explore what extent the empirical activity hierarchy of the ICF-AM is linked to the conceptual model based on the level of energy expenditure described as MET. One hundred and eight participants with lower extremity impairments were examined for the present study. A newly created activity measure, the ICF-AM using an item response theory (IRT) model and computer adaptive testing (CAT) method, has a construct on walking/moving construct. Based on the ICF category of walking and moving, the instrument comprised items corresponding to: walking short distances, walking long distances, walking on different surfaces, walking around objects, climbing, and running. The item difficulty hierarchy was created using Winstep software for 20 items. The Rasch analyses (1-parameter IRT model) were performed on participants with lower extremity injuries who completed the paper and pencil version of walking/moving construct of the ICF-AM. The classification of physical activity can also be performed by the use of METs that is often preferred to determine the level of physical activity. The empirical item hierarchy of walking, climbing, running activities of the ICF-AM instrument was similar to the conceptual activity hierarchy based on the METs. The empirically derived item difficulty hierarchy of the ICF-AM may be useful in developing MET-based activity measure questionnaires. In addition to convenience of applying items to questionnaires, implications of the finding could lead to the use of CAT method without sacrificing the objectivity of physiologic measures.

마늘 풍미유를 합리적으로 제조하는 방법을 개발하기 위하여 Autoclaving Method와 Evaporating Method에 의하여 corn salad oil에 마늘을 raw, flake, extract 형태로 전체 중량의 40%(w/w) 첨가하여 제조하였다. 이들 마늘 풍미유를 항온저장($40{\pm}2^{\circ}C$) 및 가열처리($185{\pm}2^{\circ}C$) 하면서 경시적으로 휘발성 향기 성분의 변화를 측정하여 AM 및 E'M의 적합성 및 유효성을 고찰한 결과는 다음과 같았다. 마늘 풍미유의 주요 향기성분 중 propane, pentane, diallyl disulfide, methyl allyl trisulfide, diallyl trisulfide 등은 경시적으로 감소현상을 보였으나 carbonyl인 propenal과 hexanal은 증가 추세를 보였다. 항온저장($40{\pm}2^{\circ}C$)시 형태별 총 향기 성분 함량은 raw>extract>flake의 순으로 나타났으나 향기 안정성은 AM 처리시raw>flake>extract 첨가군의 순서로 나타났으며 E'M 처리시에는 첨가 마늘의 형태별로는 뚜렷한 차이를보이지 않았다. 가열처리($185{\pm}2^{\circ}C$)시 형태별 향기 성분 함량은 항온 저장시와 동일하였으며 잔류율은 항온 저장시와는 달리 flake>raw>extract의 순으로 안정한 것으로 나타났으며 그 정도는 매우 미약하였다. E'M으로 제조된 풍미유의 향기 성분은 AM으로 제조된 풍미유의 향기 성분의 66.1% 수준으로 그 함량이 낮았으나 항온 저장시나 가열 처리시 이들의 함량 변화는 서로 유사한 경향을 나타내었다. 위의 결과에서 AM, E'M에 의해 제조된 마늘 풍미유는 마늘의 독특한 풍미를 보유하면서 상온 저장시에 상당한 기간동안 안정한 상태를 유지할 수 있을 것으로 보아 AM 및 E'M은 풍미유 제조에 합리적인 방법인 것으로 사료된다.

This study investigated the effect of extrusion conditions on microstructures and mechanical properties of AM80 magnesium alloys. The billets of magnesium alloy used for hot extrusion were prepared by permanent mold casting method, and its extrusion was hot direct extrusion with different extrusion conditions. The results of microstructural analysis showed that the main phases in the as-casted alloys were ${\alpha}-Mg$, ${\beta}-Mg_{17}Al_{12}$, and lamella $Mg_{17}Al_{12}$. Hot extrusion results, The tensile strength of the most soundly manufactured extruded bars (extrusion temp: $350^{\circ}C$, extrusion ratio: 27:1, ram speed: 2mm/s) was approximately 327MPa at room temperature. The increase in the mechanical properties of hot-extruded alloys was as a result of grain refinement by dynamical recrystallization during hot extrusion.
