H-S Lee, Y-S Lee, J-C Byun. The effects of EMG activity and blood fatigue makers on balance taping treatment by exercise type. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 271-284, 2004. The purpose of this study was to analyse the EMG activity of selected muscles with balance taping treatment and blood fatigue makers which accumulated during exercise of progressive maximal intensity. Ten male college students who did not experience any cardiovascular and musculo-skeletal disease were participated in this study. Balance taping were applied to rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinous, semimembranous, and around knee joint. Isokinetic knee joint flexion/extension force, EMG activity, lactate and ammonia as blood fatigue makers during progressive maximal intensity exercise were measured for with/without applying balance taping. The results indicated that although flexion force of total work at 60˚/sec with taping was increased applied taping did not affect to the aerobic exercise ability parameters. Lactate level as blood fatigue makers during progressive maximal intensity exercise after taping was decreased but the ammonia level did not change with same treatment. In isokinetic knee joint test at the angular velocity of 60˚/sec, 180˚/sec, and 240˚//sec the taping treatment did not affect to any selected muscle EMG activities except maximal EMG of vastus lateralis at 240˚/sec.

인터넷은 디지탈 형태의 다양한 정보를 신속하게 전달한다는 점에서 매우 각광을 받고 있다. 그러나, 대량의 인터넷 정보 중에서 자신이 원하는 정보 자원을 정확하게 많이 얻어 낼 수 있는 방법의 제공은 매우 어려운 문제이다. 본 논문에서는 인터넷 정보 자원의 메타데이타를 관리하기 위해 SeriCore라는 SGML 형식의 메타데이타 DTD(Document Type Definition)를 정의하고, 이들 메타데이타를 효율적으로 저장하고 검색, 관리할 수 있는 시스템을 설계, 구현하였다 The Internet has gained popularity because ot provides various information in digital format. However, it is very difficult to provide methods which make it possible to search adequate information resource from bulk of Internet information. In this paper, we define a SGML metadata DTD, named SeriCore, and design and implement a metadata retrieval and management system which can store, retrieve and manage the Internet metadata efficiently

The affective factors on regional anesthesia are lipophilic-hydrophilic balance of local anesthetics, protein binding, hydrogen concentration, structure of intermediate chain, and etc. Local anesthetics in solution exit in a chemical equilibrium between the basic uncharged form(B) and the charged cationic form(BH^+) by Henderson-Hasselbalch equation(PH_a=PK+log[B]/(BH^+)). The increasement of uncharged form brig about rapid onset, good quality, and long duration of anesthesia. Eight patients in group Ⅰ were given 2% lidocaine 21.7ml with 1: 200,000 epinephrine(pH 5.1), and eight patients in group Ⅱ were given 2% lidocaine 20ml with 1: 200,000 epinephrine added NaHCO_3 1.7ml(pH 7.2) to determine the epidural analgesic effect of the pH-adjusted solution. The results are summerized as follow 1. The onsets of analgesia and surgical anesthesia were significantly rapid in group Ⅱ. 2. The levels of analgesia were raised more rapidly in group.

인공해수 중에서 0.17C-Ni-Cr-Mo 합금강의 피로수명

Fatigue life of base and weld metal of 0.17C-Ni-Cr-Mo alloy steel have been investigated in synthetic seawater under smooth and notched conditions at frequencies of 4Hz and 30Hz. Most data for the alloy steel agree with that for HY-100 steel. The form of a simple power relation can be suggested as a conservative design criteria for the fatigue life in aggresive environments.

루이스 칸의 도시설계이론에 관한 고찰

Louis 1 Kahn's theoretical point of departure was the idea of 'urban renewal' and despite its incoherent processes and diagrams, his plan was perceived to be similar to his architectural concepts development. In the period of Order, Kahn offered a way to put cities into order through a hierarchical traffic system. In the period of Form, the idea of a system was superseded by the architecture of the 'viaduct concept' At that time, however, Kahn intended to apply form to the urban community, reminiscent of the central sanctuary in medieval churches, by converging institutions within an urban core. In the period of Room, he posited that a 'street' is a 'room,' if agreed upon by the people who use it. Thus, people made explicit distinctions between streets and these distinctions were reinforced with the form and light structure of each street. The essence of Kahn's method lay precisely in the hierarchical traffic system and the self-rehabilitation of the system. This was just what the city could be-a sense of place of self-generating ability. According to Kahn, this is what it meant to seek "Beginning."

The purpose of this research is to obtain the heat transfer characteristics of the absorber type solar collector. This new system moving by time and degree. The second system had the solar tracking system. The x-y axis were designed at intervals of 0.33˚/min and 0.16˚/min respectively. In this system the absorber specification was 1OOLX80Φ1.4t. This experiment was conducted from July to August. 2002. The temperature of solar collector was reached about mean temperature 250℃.

The mushroom pickles were prepared as a processed mushroom product. The changes in pH, total acidity, brix, color and texture of the mushroom pickles (Lentinus edodes, Pleurotus ostreatus, Agaricus bisporus and Pleurotus eryngii) were measured during storage at 4℃. In addition, sensory evaluations on the mushroom pickles were performed. While the pH of Lentinus edodes and Pleurotus ostreatus pickles declined slowly, the pH of Agaricus bisporus and Pleurotus eryngii pickles declined rapidly during storage, The total acidity of Lentinus edodes pickles rose slowly, while the acidity of Pleurotus ostreatus, Agaricus bisporus and Pleurotus eryngii pickles rose rapidly, As for the color of mushroom pickles, "L", "a" and " b" values changed slightly. The changes in texture were determined by a rheometer, Hardness, cohesiveness, springiness, gumminess and brittleness of Lentinus edodes pickles were lower than those of the other mushroom pickles. In the sensory evaluation of mushroom pickles, Lentinus edodes showed higher acceptability ratings than the other mushrooms in taste, color, clearness, texture and overall acceptability. This study showed that among the mushrooms tested, Lentinus edodes was the most acceptable mushroom pickle for storage.

Effects of TiO₂additions on the crystallization behavior of a glass with a composition of 50.0wt% CaO·MgO·2SiO₂-40.0wt% 3CaO·??-10wt% MgO·TiO₂system were investigated by ovserving the microstructure of the crystallized products. The results obtained are summarized as follows; 1. The major crystalline phases are indentified by X-ray diffraction as apatite(??), wollastonite(CaSiO₃), whitlockite[β-Ca₃(PO₄)₂], MgTiO₃and diopside[CaMg(SiO₃)₂]. 2. The glass transition temperature(??) and the softening point(??) are shifted to the lower temperature by increasing of TiO₂content. 3. The apatite and MgTiO₃crystallization are increased by increasing of TiO₂content. 4. The exothermic crystallization peak of MgTiO₃appear in the sample which contained more than 15.6wt% of TiO₂.

A flow system was used to measure the equilibrium solubilities of Benzoic acid(308, 318, 328 K), Phenol(303, 309 K) and Menthol(303, 313, 323 K) in supercritical Carbon dioxide at various temperatures and a ranged of pressures. The observed data were correlated with a thermodynamic model based on the Peng and Robinson equation of state. The critical properties and acentric factor for Menthol that could not be available in literature were predicted by the method proposed in this work as well as Lydersen's method.
