Recent proliferation of building information modeling (BIM) has actively stimulated integrated utilization of geometric (graphic) and non-geometric (non-graphic) data. Nevertheless, physically and logically, linking and maintaining these two different types of data in an integrated manner requires enormous overhead efforts for practical implementation. In order to address this problem, this paper proposes a concept and structure of the object breakdown structure (OBS) that facilitates advanced BIM implementations in an automated and effective manner. Proposed OBS numbering system has secure rules for organizing graphic objects in full considerations of effectively integrating with non-geometric data (e.g. cost and schedule). It also removes repetitive linking process caused by design changes or modifications. The result of applying this concept to a housing project revealed that only 120 definitions controled over 6,000 graphic objects for full integration with cost and schedule functions.

This study was peformed to evaluate antithrombotic activities and anti-inflammatory effects of Kami-BoyangHwanoh-Tang(KBHT). The major findings were summarized as follows. In experiment of anti-thrombotic effect; KBHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 50 %). KBHT increased platelet number significantly and also KBHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; KBHT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, $100\;{\mu}g/^{ml}$, and also inhibited ROS production in a concentration-dependent degree as compared with the control group in RAW 264.7 cell line. KBHT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, and also decreased IL-6 and $TNF-{\alpha}$ production in liver tissue, but increased $IL-1{\beta}$ production in liver tissue of acute inflammation-induced mice. KBHT increased survival rate at 3rd day in mice with lethal endotoxemia induced by LPS. These results suggest that KBHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as endometrosis, myoma, pelvic congestion, chronic cervicitis, chronic pelvic inflammatory disease and so on.

Objectives: The purpose of this study is to find out the characteristics of dysmenorrhea patients with the Inbody test results by Sasang constitutions. Methods: The data from the 541 participants were collected using a structured measurement of menstrual pain. Based on the survey responses, we had 329 women with dysmenorrhea as the test group and 212 women without dysmenorrhea as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and undergo Inbody test. Results: The result of a comparison of the test and control groups showed that the DSOM test showed that the scores of blood deficiency, qi stagnation, blood stasis and phlegm were significantly higher in dysmenorrhea. The result of the taeumin's test groups showed that the DSOM test showed that the scores of heat were significantly higher. For the Sasang constitution, there is a difference on the cause of the outbreak. Taeumin from blood deficiency, blood stasis, dampness, heart, kidney, phlegm and lung is associated with dysmenorrhea. Soeumin from blood deficiency, qi stagnation, blood stasis, liver, heart, spleen and phlegm is associated with dysmenorrhea. The ratio of overweight of taeumin was low in blood deficiency and yin deficiency. The ratio of lowweight of soeumin was high in heat. Conclusions: The DSOM test showed that the scores of blood deficiency, qi stagnation, blood stasis and phlegm were significantly higher in dysmenorrhea.

Objectives: This study is to identify the effect of sex education by school doctor of Korean medicine on elementary school students from fourth to sixth-grade. Methods: Eighty three students who received four sex eduction lectures by school doctor of Korean medicine were assigned as experimental group while 132 students who did not receive any sex education were assigned as control group. This study observed the changes in students’ sexual knowledge and sexual attitude before, after and three months after the sex education program. Results: Experimental group showed positive changes on sexual knowledge (male p=0.000, female p=0.046) and sexual attitude (male⋅female p=0.000). Three months after the conclusion of sex education program, the follow-up evaluation showed decline in effect of education, which suggests a need for continuous sex education. As students showed high level of satisfaction, we expect school doctor of Korean medicine can improve knowledge on health and further increase familiarity in Korean medicine by this kind of sex education Conclusions: Sex education by school doctor of Korean medicine for elementary school students from fourth to sixth grade has effectively changed sexual knowledge and attitude.

Purpose: Uterine leiomyomas (fibroids) are common estrogen-dependent uterine tumors. Houttuynia cordata thunberg has cancer-preventing properties and often used in Chinese medicine. In the present study we used Houttuynia cordata thunberg to determine its effect on cell proliferation and apoptosis in human uterine leiomyoma cells. Methods: Primary cultured human uterine leiomyoma cells were treated with Houttuynia cordata thunberg. Cell viability analysis was analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTS) assay and Flow cytometry was performed to ascertain the effects Houttuynia cordata thunberg. Expression of cell cycle related proteins and apoptosis related proteins were evaluated by Western blot analysis. Results: Cell viability was significantly influenced by Houttuynia cordata thunberg treatment in a dose-dependent manner in leiomyoma cells compare to normal myometrial cells. Flow cytometric analysis showed that Houttuynia cordata thunberg induced Sub G1 arrest. DNA fragmentation assay was carried out and apoptosis was detected. Activation of caspase-3, down-regulation of Bcl-2, with concomitant increase in p21 was observed. Houttuynia cordata thunberg treatment of uterine leiomyoma cellsresulted in a concentration-dependent cell death induced via the caspase dependent mechanism. Conclusion: These results suggest that Houttuynia cordata thunberg treatment in uterine leiomyoma cells leads to growth inhibition and induced apoptosis. These results suggest that Houttuynia cordata thunberg will be a promising agent for use in therapeutics agents against human uterine endometrial cancer.

Purpose: In spite of many arguments on the result of WHI (Women's Health Initiative) study, no one can deny the necessity for researches on the alternative treatment to HRT (hormone replacement therapy). In this study, the author wanted to investigate the method of precedent acupuncture RCTs (randomized controlled trials) to make out the appropriate acupuncture study design on postmenopausal and perimenopausal hot flashes in Korea. Methods: Precedent studies were investigated using Pubmed search and key-words "acupuncture and hot flash", "acupuncture and menopause", "acupuncture and vasomotor", limited to RCT, from 2000 to 2008 April. Results: As a result. 10 studies were searched. In the hereafter studies, multi-center clinical trials which consist of population group of postmenopausal and perimenopausal women that would be pre-stratified and more than 50 patients per treatment arm seem adequate. Sham control study can make out the proper consequence because many people are get used to acupuncture in Korea. Flexible choice of acupoints addressed an individual's symptoms using standardized algorithm is recommended. Treatment consist of 4 weeks' observation, 11 acupuncture sessions during 7 weeks, follow-up of 3 months or more after treatment and hot flash score as a primary outcome measure seem appropriate. After all, higher level of description according to global standard must be obtained in the study report and publishing. Conclusion: The researchers should develope the methodology of acupuncture clinical trial on the postmenopausal and perimenopausal hot flashes.

Objectives: The purpose of this study is to find out the health condition and the etiology in oriental medicine of the high school girls menstrual disorders by Sasang constitution. Methods: The data from the 795 participants were collected using a structured menstrual history questionnaire. Based on the survey responses, we had 97 adolescents with menstrual disorder as the test group and 97 adolescents without menstrual disorder as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and respond to the DSOM and undergo Inbody. We identified significant variables for dysmenorrhea from comparison between the test and control group. Results: The DSOM test showed that the scores of qi stagnation, static blood, cold, dampness, phlegm, heart, kidney were significantly higher in dysmenorrhea, scant menstruation, menstruation at irregular intervals. For the Sasang constitution, there is a difference on the cause of the outbreak. Soyangin from yin deficiency, dryness and blood deficiency is associated with menstrual disorders. Taeumin from cold, dampness and qi deficiency is associated with menstrual disorders. Soeumin from heart, qi stagnation, static blood and spleen is associated with menstrual disorders. Conclusions: For the Sasang constitution, there is a difference on the cause of the outbreak. The result of a comparison of the test and control groups showed that there's no relevance to the body fat mass and body fat percentage with menstrual irregularities.
