This study was conducted to investigate the effect of parity and region on the live body charateristics of Hanwoo cows. The data used were logissimus muscle area (LMAU), back fat thickness (BFTU), marbling score (MSU), and p8 point fat thickness (P8 FTU), by ultrasound from 1,239 heads of hi-lok branded Hanwoo cows. Based upon ultrasound characteristics of LMAU, BFTU, MSU and P8 FTU were significantly high in Hanwoo cows in Hwacheon area. Live body characteristics were increased with the parity, however estimated value tended to decreased after sixth parturition. Also, comparative of pre or after parturiti- on on the live body characteristics, pre parturition value showed little lower than after parturition

This study was to invesigate the effect of dietary supplemention of Pozzolan, Chromium-methionine chelate and rhus verniciflua stokes additive feed on growth performance and ultrasound live body characteristics in finishing Hanwoo steer. The animal used in the experiment were a total of 17 heads and weighted 577.09±35.90㎏. The experimental diets were basal hi-lok branded only concentrat and rice straw and 4% Rhus, 0.4% Cramin and 2% Pozzolan, which additice in basal diet. Individually average daily gain was tended to decreased with treated group. Ultrasound back fat thickness and marbling score were not significantly different(p<0.05)between teratment, however Pozzolan additive treat was showed tend to increased. Longissimus muscle area was showed tended to decreased in the Pozzolan treatment.

This study was carried out to determine the maintenance and social behavior characteristics of Hanwoo steers by season. Forty eight Hanwoo steers were video-recorded at 15, 17 and 19 months of age for behavior measurement. Hanwoo steers spent more feeding time (p<0.05) in autumn than in summer and/or winter. Standing time was linearly increased (p<0.05) along with seasonal transition, from summer to winter. The rice straw intake speed was the fastest the summer, whereas the concentrate intake speed was relatively fast in winter. Furthermore, Hanwoo steers showed more behavior time and count for lying down (p<0.05) and drinking (p<0.05) in summer than in autumn and winter. Also, Hanwoo steers spent less count (p<0.05) self grooming and scratching in summer.

  This paper presents the conceptual framework for estimating and predicting system’s susceptibility to failure as function of condition parameter value which is representing the current status of performance measure using on-line performance reliability.

We have successfully developed the KASI (Korea Astronomy and Space Science Institute) Solar Imaging Spectrograph (KSIS), which has been originally upgraded from the KASI solar spectrograph that was able to record solar spectra for a given slit region and to inspect the response function of narrow band filters. A prototype KSIS was developed in 2004 by using a scanning mirror in front of the spectrograph slit and a SBIG ST-8XE CCD camera. Its main disadvantage is that it took a long time (about 13 minutes) to scan a whole active region. In this work, we have upgraded the KSIS by installing a much faster Dalsa 1M15 CCD camera, which gives a data acquisition time of about 2.5 minutes. The software for KSIS was also improved for the new CCD camera on the basis of component-based development method. We have successfully made a test observation for a simple and small active region (AR10910) using the improved KSIS system. Our observations show that H-alpha images for several wavelengths have typical features in a sunspot as well as a H-alpha centerline image is quite similar to a BBSO H-alpha image, demonstrating the capability of the KSIS system.

Objective: <千金方(Qianjinfang)> which documents a great amount of prescription of Acupuncture and moxibustion bikes an important role during the development of acupuncture and moxibustion. Thus, it have given rise us to the research-situation of Tang Dynasty China of previous period. This study was to outline the rules of choosing acupoints as well as the prescriptions of contemporary times in reference with <千金方(Qianjinfang)>, and to discuss the conception of acupuncture and moxibustion in <千金方(Qianjinfang)>. Method: Based on <千金方(Qianjinfang)>, the parameters were categorized to a certain scope, syndromes in different type were classified. Also numbers of acupoints, route of meridians locations, utilities of special acupoints even prescription methods were statistically analyzed in reference with <千金方(Qianjinfang)>. Results & Conclusion: Acupuncture prescription in <千金方(Qianjinfang)> was mostly presented by single acupoint and this was basic prescription of its rule of choosing acupoints. Choosing acupoint for the majority of various diseases started from choosing meridians with the disorder, but no rules for choosing acupoints was clear. There was basically various methods in choosing acupoints, but little were used by Biao-Ii meridian choosing method (表裏經配穴.) In the high frequency of use, wu-shu acupoints was higher used than other specific acupoints (特定穴). While wu-shu acupoints treated the major parts of the diseases, shu-mo acupoints were strictly used on system. Consequently : The theoretical basis originating the choosing rules of the acupoints and prescriptions was shown in <千金方(Qianjinfang)> as representative clinical reference, through which it was valuable to analyze the prescription rule and specificity of the acupoints.

In order to perform the protein analysis using the paraffin sections previous fixed with formalin, we applied the ImmunoMemBlot (IMB) method1) to detect the epitopes of target proteins with specific antibodies. In this study the protein extracts were obtained from the paraffin sections of each representative case of ameloblastoma, adenomatoid odontogenic tumor (AOT), and normal gingiva, and more a protein extract from fresh tissue of ameloblastoma was also compared to evaluate the IMB results used with 24 different antibodies. First of all, in the comparison between the paraffin section extract and fresh tissue extract of ameloblastoma, the latter consistently showed more positive IMB reaction than the former. Meanwhile, the paraffin section extract of ameloblastoma was more comparable with that of normal gingival, disclosing that most of proliferating genes, oncogenes, and apoptosis related genes, i.e., PCNA, CDK4, c-erbB2, CEA, p53, Bax, Bad, FLIP, FAS, Bcl-2, p21, N-ras, MMP-2, MMP-9, caspase-3, -8, -9, were highly expressed in ameloblastoma, but EGFR, HGF, and VEGF were similarly expressed both in the ameloblastoma and in normal human gingiva. On the other hand, the comparison between ameloblastoma and AOT both in the immunohistochemistry and IMB using their paraffin section extracts clearly demonstrated that the ameloblastoma showed more expression of proliferating genes and oncogenes while the AOT showed more expression of apoptosis related genes, i.e., Bax, Bad, FLIP, and caspase-9. Taken together, these data suggest that the IMB can be used for the primary screening of quantitative protein analysis using the paraffin section extract, and that the IMB results could be evaluated in conjunction with the immunohistochemical observation.

본 연구는 현재 수행중인 "한국형 포장 설계법 개발과 포장성능 개선방안 연구"의 일환으로 역학-경험적 포장 설계법에 사용될 교통하중 입력변수를 정량화하기 위해서 실시하였다. 교통하중 정량화를 위하여 기존의 ESAL 개념이 아닌 축하중 스펙트럼을 이용하였다. 이를 위하여 교통량 통계 연보내 교통량 자료를 가지고 일반 국도에 대한 대표 축하중 조사지점을 차로별, 지역특성별 구분에 따라 33개 지점을 통계적 방법을 이용하여 선정하였다. 그리고 선정된 대표 지점을 대상으로 축하중 계측기를 이용하여 각 차종에 대한 축하중을 조사하였다. 측정된 축하중 자료는 각각 분류된 조건에 따라서 축하중 스펙트럼으로 표준화하였으며, 그 방법으로 누적밀도함수인 S-커브 곡선을 이용하여 각 조건별 계수를 제시하였다.
