In order to find if there are any differences in techniques and scores of Judo matches by height and weight of athletes, video tapes and records of 120 matches by 544 male Judo players who participated in the 2nd Tamra National Judo Championships were examined, which resulted in the following outcomes: 1. It was found that light weight players tend to use frequently such techniques as Ashi-Waza, Te-Waza and Osae-Komi-Waza in sequence with higher probability to win when they fought with those smaller in height(p〈.001). In contrary, when they fought with those similar to or. taller in height than themselves, they rather used Te-Waza, Ashi-Waza and Koshi-Waza in the order of frequency(p〈.001). 2. In case of middle weight players, they favored to use frequently techniques such as Ashi-Waza, Te-Waza, Osae-Komi-Waza and Koshi-Waza in order with more probability to win when they fought with smaller opponents(p〈.001). In contrary, however, when they fought with those similar to or taller in height than themselves, they tried to use Ashi-Waza, Te-Waza, Osae-Komi-Waza and Koshi-Waza in the order of frequency significantly(p〈.001). 3. Heavy weight players were found to attach frequently to such techniques as Ashi-Waza, Osae-Komi-Waza, Te-Waza and Koshi-Waza in sequence with possibility to get higher scores when they fought with smaller competitors(p〈.001). In contrast, when they fought with those similar to or taller in height than themselves, they tended to use Te-Waza, Ashi-Waza, Osae-Komi-Waza and Koshi-Waza in order, but the order of probability to win higher scores turned out to be Ashi-Waza, Te-Waza, Osae-Komi-Waza and Koshi-Waza(p〈.001). From the above findings, it became evident that Te-Waza, particularly Seoinage as a kind of Sutemi-Waza, was used most frequently regardless the difference of weight and height. In case, however, the competitor was smaller than the player himself, Ashi-Waza was favored. Among keeping techniques, Osae-Komi- Waza was frequently used, while Ma-Sutemi-Waza, Koshi-Waza, Shime-Waza and Kansetsu-Waza were rarely used compared to other Sutemi-Waza. Based on this study, it would be recommended for those who want to be good players to acquire effectively those techniques that are fit to their own physical conditions like weight and height and to develop new techniques that can defend themselves more effectively through sys0tematic and continuous training programs.

Background : The necessity of unify and standardize codes used at hospital has been emphasized since OCS (Order Communicating System) was adopted. Therefore, the purpose of this study were to standardize operation code by continuous training of the ICD-9-CM code that is used as standard code in OCS program at operating room. Method : In 400 operation data, operation code entered in OCS program at operating room was compared to operation name recorded in medical record. In addition, a matching rate between input data of operation code by medical record department and computing input data of operation code in 3,710 cases was compared for each department. User operation name and operation code were matched and major diagnosis by operation department and operation name were also matched. Results : User operation name was reflected in operation classification code in detail, and operation code entered on user was registered. Input rate and matching rate of operation code were gradually improved after improvement activity. In particular, a matching rate was high at ophthalmology where operation name is segmented. Plastic surgery and orthopedics with a lot of emergency operation and comprehensive operation name show low input rates. Conclusions : As the medical field makes progress in computerlization, awareness of information exchange and sharing becomes higher. Among codes to classified medical institution, codes related to surgical operation are all different by user of hospital and department. Computerlization and standardization is essential. And when efforts of standardization continue in alliance with individual hospital and institution, initiative of preparing medical policy data at a national level will be accelerated.

The Electronic Nose has been designed to provide objective and reproducible aroma discrimination on a wide variety to human nose. The sensor array in combination with sophisticated chemometrics and artificial neural network software provides the output displaying the closeness of difference in aroma patterns of different samples. As an application the system has been used to discriminate of the fresh and decomposing apples and oranges. The discrimination has been successfully demonstrated.

The XylH gene (1,167-bp) encoding a novel hemicellulase (41,584 Da) was identified from the genome of Microbacterium trichothecenolyticum HY-17, a gastrointestinal bacterium of Gryllotalpa orientalis. The enzyme consisted of a single catalytic domain, which is 74% identical to that of an endo-β-1,4-xylanase (GH10) from Isoptericola variabilis 225. Unlike other endo-β- 1,4-xylanases from invertebrate-symbiotic bacteria, rXylH was an alkali-tolerant multifunctional enzyme possessing endo-β-1,4-xylanase activity together with β-1,3/β-1,4- glucanase activity, which exhibited its highest xylanolytic activity at pH 9.0 and 60oC, and was relatively stable within a broad pH range of 5.0-10.0. The susceptibilities of different xylosebased polysaccharides to the XylH were assessed to be as follows: oat spelts xylan > beechwood xylan > birchwood xylan > wheat arabinoxylan. rXylH was also able to readily cleave p-nitrophenyl (pNP) cellobioside and pNP-xylopyranoside, but did not hydrolyze other pNP-sugar derivatives, xylobiose, or hexose-based materials. Enzymatic hydrolysis of birchwood xylan resulted in the product composition of xylobiose (71.2%) and xylotriose (28.8%) as end products.

Background/Objectives: Central venous access is an essential part of neonatal care. In addition, a thorough knowledge of the techniques for cannulation and placement of venous lines Methods/Statistical analysis: We describe percutaneous cannulation of the subclavian vein and case of breakage of guidewire during cannulation in a infants and describe the condition. Findings: It showed that the distal portion of the guidewire had been cut and left twisted under the clavicle. The tip of the guidewire was found in the tissue below the subclavian vein and surgically removed. Improvements/Applications: The standard approach, as well as potential difficulties and other considerations are described with literature review.

Effect of dealloying condition on the formation of nanoporous structure in melt-spun $Al_{60}Ge_{30}Mn_{10}$ alloy has been investigated in the present study. In as-melt-spun $Al_{60}Ge_{30}Mn_{10}$ alloy spinodal decomposition occurs in the undercooled liquid during cooling, leading to amorphous phase separation. By immersing the as-melt-spun $Al_{60}Ge_{30}Mn_{10}$ alloy in 5 wt% HCl solution, Al-rich amorphous region is leached out, resulting in an interconnected nano-porous $GeO_x$ with an amorphous structure. The dealloying temperature strongly affects the whole dealloying process. At higher dealloying temperature, dissolution kinetics and surface diffusion/agglomeration rate become higher, resulting in the accelerated dealloying kinetics, i.e., larger dealloying depth and coarser pore-ligament structure.

<P><B>Abstract</B></P> <P>This study examined the effect of Ca addition on the selective oxidation of the Al<SUB>3</SUB>Mg<SUB>2</SUB> phase in an Al-5 mass%Mg alloy during oxidation at 400 °C and 500 °C for 72 h. Ca addition led to the formation of the Al<SUB>4</SUB>Ca and Laves_C36 phases besides the primary Al solid solution and Al<SUB>3</SUB>Mg<SUB>2</SUB>. After the oxidation test, there was no significant oxidation in both the Ca-free and Ca-added alloy samples and no visible change in the surfaces between them at 400 °C, which is lower than the melting temperature of Al<SUB>3</SUB>Mg<SUB>2</SUB> (451 °C). At 500 °C, the surface of the Ca-free alloy showed the formation of oxide blisters, which was not observed in the Ca-added alloy. The presence of an Al<SUB>4</SUB>Ca phase at the grain boundaries led to the formation of multi-element oxides containing Al, Mg, and Ca, which can contribute to the formation of a compact oxide layer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Ca addition in Al-Mg alloy forms two Ca based intermetallic compounds. </LI> <LI> Coexistence of Al<SUB>4</SUB>Ca and Al<SUB>3</SUB>Mg<SUB>2</SUB> phases forms Ca-Mg-Al based oxides after oxidation. </LI> <LI> Ca-Mg-Al based oxides control oxide blister formation from Al<SUB>3</SUB>Mg<SUB>2</SUB> during oxidation. </LI> </UL> </P>
