  • This study was performed to determine the effectiveness of poloxamer/sodium alginate mixture(PX/SA) barriers on prevention of post-operative peritoneal adhesion in dogs. Fifteen mongrel dogs were divided into three experimental groups: non-treated group, 2% Sodium Carboxymethylcellulose (SCMC) treated group and PX/SA treated group. In order to induce adhesions, the anti-mesenteric serosa of the ileum was exteriorized and then abraded in a standard manner by scraping with a scalpel blade to create homogeneous petechial hemorrhagic surface over a 1 ${\times}$ 1 cm area. Solution of SCMC was allowed to spread across the intraperitoneal organs through a catheter using a syringe. PX/SA was simply coated over the abraded tissues. On day before and day 1, 4, 7, and 14 after operation, venous blood specimens were collected for measurement of RBC, total WBC and fibrinogen. The adhesions were blindly assessed 3 weeks later by using a computerized tensiometer. The RBC, total WBC and fibrinogen values of three groups showed no statistical significances. The mean tensile strength(gram force, gf) of formed adhesions on day 21 after surgery was 173.05${\pm}$113.48 in the non-treated group, 111.42 ${\pm}$ 38.25 in the SCMC group, and 69.00 ${\pm}$ 45.07 in the PX/SA group. The tensile strength values for adhesion seperation in PX/SA group was lower than those in SCMC group(p < 0.05) and significantly lower than those in the non-treated group(p < 0.05). Our data suggested that PX/SA should be effective on reducing peritoneal adhesion formation in dogs compared with SCMC. PX/SA may be applicable to preventing post-operative intraperitoneal adhesion in dogs.

  • Orthopedic rapid maxillary expansion(RME) has been a common treatment modality used to widen narrow maxillae in young children. However, since more skeletally matured adolescents or adults has closed midpalatal suture, the result of RME was undesirable because of dental tipping with little or no basal skeletal movement and resulted to many other complications. After such treatment, complications often occurred such as alveolar bending, compression of periodontal ligament, extrusion, buccal tipping, and severe relapse. Thus, surgically assisted rapid maxillary expansion(SA-RME) is required, especially for patients over 14 years old, to skeletally release maxillary expansion. We used two methods of maxillary expansion surgery. Surgically assisted rapid maxillary expansion(SA-RME) & surgically assisted posterior segmental expansion(SA-PSE) were used for narrow maxilla. The study was divided into two groups(SA-RME group and SA-PSE group). SA-RME group was consisted of 2 males and 4 females, and the ages of materials ranged from 15 years to 25 years with a mean of 20.2 years. SA-PSE group was consisted of 1 male and 5 females, and the ages ranged from 13 years to 23 years with a mean of 18.7 years. Dental study models were fabricated before starting the expansion and immediately after the expansion was completed. It was fabricated again 1 month later, 3 months later when the expansion device was removed, and 6 months later after the expansion was completed. A repeated measures analysis of variance(ANOVA) test was applied to assess changes between each groups over time. The amount of expansion and the amount of tipping movement each in both groups were compared by using paired t-test and it was also compared between each subjects within the group by using independent t-test. Both SA-RME and SA-PSE group showed stable results, but SA-PSE group showed statical significance in tipping movement of second premolar. We compared 6 patients who recieved SA-RME with 6 patients who received SA-PSE, and appraised the clinical usefulness.

  • This study was conducted to evaluate the vasorelaxant effect of DangGuiSu-San and SamHwangSaSim-Tang extract on contracted rabbit carotid artery. To study the effect of DangGuiSu-San and SamHwangSaSim-Tang extract on contracted rabbit carotid arterial strips, arterial strips with intact or damaged endothelium were used for experiment using organ bath. The pre-contracted arterial strips with Phenylephrine(PE) was treated with various concentrations of DangGuiSu-San and SamHwangSaSim-Tang extract(0.01, 0.03, 0.1, 0.3 and $1.0mg/m{\ell}$). To determine the mechanisms of DangGuiSu-San and SamHwangSaSim-Tang-induced vasorelaxant, DangGuiSu-San and SamHwangSaSim-Tang extract were infused into contracted arterial rings which had been pretreated by indomethacin(IM), tetraethylammonium chloride(TEA), $N{\omega}$-nitro-L-arginine ($_L-NNA$), methylene blue(MB). And calcium chloride(Ca) 1 mM was infused into precontracted arterial ring induced by PE after treatment of DangGuiSu-San and SamHwangSaSim-Tang extract in $Ca^{2+}$-free krebs solution. DangGuiSu-San and SamHwangSaSim-Tang extract revealed significant relaxation on PE-induced arterial contraction. DangGuiSu-San and SamHwangSaSim-Tang extract also had an effective relaxation to the intact endothelium arterial ring. SamHwangSaSim-Tang extract on contracted rabbit carotid artery is related with NO-cGMP pathway. Pretreatment of DangGuiSu-San and SamHwangSaSim-Tang extract inhibited the contraction by influx of extracellular $Ca^{2+}$ in contracted arterial ring induced by NE. This study indicated that the relaxation effect of SamHwangSaSim-Tang extract on contracted rabbit carotid artery is related with NO-cGMP pathway. Pretreatment of DangGuiSu-San and SamHwangSaSim-Tang extract inhibited the contraction by influx of extracellular $Ca^{2+}$ in contracted arterial ring induced by NE.

  • This paper proposes a Simulated Annealing(SA) algorithm for cluster-based Multicast Routing problems. Multicasting, the transmission of data to a group, can be solved from constructing multicast tree, that is. the whole network is partitioned to some clusters and the clusters are constructed by multicast tree. Multicast tree can be constructed by minimum-cost Steiner tree. In this paper, an SA algorithm is used in the minimum-cost Steiner tree. Especially, in SA, the cooling schedule is an important factor for the algorithm. Hence, in this paper, a cooling schedule is proposed for SA for multicast routing problems and analyzed the simulation results.

  • This paper is bibliographical study on Chonshin-sarikyung(全身舍利經 sutra scroll) which is owned by Sungbo museum Woljung-sa(月精寺) in Odae-san(五臺山). Through the investigation with documents and other historical materials in relation to the history of Woljung-sa, I found new prospect that Elder Yuyun of Suda-sa changed name of Woljung-sa at the middle of 13th century. Therefore, as it is considered that construction of Palgakgucheungsuktab(八角九層石塔 Octagonal Nine-storied stone Pagoda) and completion of Chonshinsarikyung were closely related to the rebuilt of Woljung-sa, it is proved that Palgakgucheungsuktab and Chonshin-sarikyung had been completed at this rebuilt period.

  • Objective : This study researched the application of Sa-am acupuncture for the treatment of hiccup. Methods : We investigated the literature for Sa-am acupuncture treatment and traditional acupuncture treatment for hiccup. Result & Conclusion : In traditional oriental medicine, hiccup is considered to be caused by uprising stomach gi, whereas, in Sa-am acupuncture, it is considered to be caused by weakness and impurity of lung gi. In Sa-am acupuncture, hiccup is divided into five classes; reverse hiccup (treated with large intestine tonification), wind hiccup (treated with liver tonification), fire hiccup (treated with heart tonification), damp hiccup (treated with spleen tonification) and cold hiccup (treated with kidney tonification). In traditional oriental medicine, hiccup is treated by way of lowering the uprising stomach gi, while, in Sa-am acupuncture, hiccup is treated by way of removing whichever of the original cause of hiccups (impurity of large intestine, damage to liver, dry heat of heart, impairment of spleen, exhaustion of kidney) caused the weakness and the impurity of lung gi. In Sa-am acupuncture, the therapeutic mode for all the five causes of hiccups is tonification mode.

  • The SA filters have a very flexible structure by limiting the maximum subwindow size. This flexible structure presents an effective trade-off between the complexity and performance of the filters. In this paper, experimental results showing the performance variation according to the change of filter order and subfilter type(such as max, min, exclusive-OR, mod) are presented. We designed optimal SA filters minimizing MSE for the various noise conditions. These results show several new properties of SA filters.

  • After the period of the Three Kingdoms Korean transportation architecture had been changed from the characteristics of the administration organization supporting the kings ruling system and gradually the characteristics as transportation architecture had cleared and diversified in accordance with the functions and characteristics of it. With this it was found that Korean transportation architecture like YukSa(驛舍), ChamYuk(站驛), GaekSa(客舍), JinSa(津舍), DoSa(渡舍), WonWoo(院字), JuMak(酒幕) and etc. had been developed variously and the architectural characteristics had developed with the functions and characteristics of transportation architecture. Some of them ,for example YukSa, ChamYuk, GaekSa, JinSa, DoSa, had the characteristics of the government office, so they had fundamental dignity of Korean wooden architecture on tile roof. But the WonWoo which was used by all of the people from the king to the people, had the characteristics of half-government and half-private. And the space of WonWoo was divided by the social position, the sex and the difference of temperature between summer and winter. And it was mostly located at the place away from the haunts of men, the form of it was the mud wall hut of the straw-thatched cottage like Sinhyewon of Mungyungsaejae and it was different from the station building of the characteristics of government office.

  • The present study was undertaken to investigate the effect of low temperature and salicylic acid(SA) on the chilling tolerance of acclimated and nonacclimated cucumber(Cucurmis sativus L.) seedlings. The acclimation phenomenon was characterized in chilling-sensitive cucumber seedlings and found to have a significant effect on the survival and shoot dry weights. The injuries experienced by the acclimated seedlings in the third leaf stage were on average smaller by half than those experienced by the nonacclimated seedlings. Chilling also caused a large increase in the free proline levels, regardless of the acclimation status. Exogenous treatment with SA(0.5mM) resulted in improved growth and survival of the nonacclimated chilled seedlings, indicating that SA induced chilling tolerance and SA and acclimation had common effects. The application of cycloheximide in the presence of SA restored the acclimation-induced chilling tolerance. The elevated proline level observed in the cold-treated and SA-treated plants was more pronounced in the light than in the dark at a chilled temperature, indicating that endogenous proline may play a role in chilling tolerance by stabilizing the water status in response to chilling. From these results it is suggested that SA provided protection against low-temperature stress by increasing the proline accumulation, and pre-treatment with SA may induce antioxidant enzymes leading to increased chilling tolerance.

  • This study is on architectural characteristics of the existing ㅁ-shaped Yo-Sa with two stories in Buddhist temple. The Yo-Sa has had the function of space for not only monasticism but also living of buddhist priests and been one of the important spaces in Buddhist temple from the beginning of it. The Yo-Sa with two stories appeared mostly in the later Chosun Dynasty, so the origin of the Yo-Sa with two stories is thought that it might relate to the circumstances of temples in the later Chosun Dynasty. Having got in the period of Chosun Dynasty, Buddhism lost the power that he has enjoyed since Korea Dynasty was established and the economic power of temples as well. Because of a change for the worse, the Buddhist priests should manage with reduced income and combine many buildings with various functions into a singular to overcome their circumstances. Therefore a waekened economic power might be a primary factor which urged to change form of Yo-Sa from one-storied to two-storied. The ㅁ-shaped Yo-Sa with two stories have the Dae-Bang-Chae for worship, Seung-Bang for Buddhist's living room in the bottom floor and garnering spaces to store up the agricultural produce, miscellaneous article, etc in the top floor. The composition methods depend on the condition of the lay of land, intentional design, and so on. Therefore, the ㅁ-shped Yo-Sa with two stories shows the diversity of space composition and architectural characteristics.
