The purpose of this study is to measure the effects on the regional economy from the Jeju International Wind Ensemble Festival. In order to examine the economic ripple effects of the festival, we examine its impact on the local economy using two regional (Jeju-National) industry-related models based on the 2013 Jeju Region Input and Output Table. We also compare how the Jeju International Wind Ensemble Festival is growing and affecting the regional economy through a comparison between 2017 and 2018. Comparing the results of a production-inducing and value added-effect analysis of the induced industries from investment expenditures for the Jeju International Wind Ensemble Festival, the production-inducing effects increased by 2.1 times-from 9.05 billion won in 2017 to 18.7 billion won in 2018. The value-added effect increased by 2.2 times, from nearly 4.3 billion won in 2017 to nearly 9.2 billion won in 2018. The analysis shows that the Jeju International Wind Ensemble Festival contributes greatly to an income increase for local residents. In order to enhance the effects of the Jeju International Wind Ensemble Festival, it is necessary to use policies that link culture and tourism in Jeju.

The study was designed to investigate the effects of Mixture of Yukgunja-tang and Bambusae Caulis in Liquamen (YTBCL) on the change of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in rats, and further to determine the mechanism of action of YTBCL. The results in rats were as follows ; YTBCL 25 ${\mu}l$ significantly decreased rCBF and MABP compared with basal condition. YTBCL 100 ${\mu}l$ significantly increased rCBF compared with basal condition, but decreased MABP compared with basal condition. YTBCL 50 ${\mu}l$ significantly increased rCBF compared with basal condition, but MABP was somewhat decreased compared with basal condition. The VTBCL 50 ${\mu}l$-induced increase in rCBF was significantly inhibited by pretreatment with methylene blue (10 ${\mu}g$/kg, i.p.), an inhibitor of guanylate cyclase and indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase. The YTBCL 50 ${\mu}l$-induced decreased MABP significantly increased by pretreatment with methylene blue but was inhibited by indomethacin. This results were suggested that the mechanism of YTBCL was mediated Dy guanylate cyclase.

Objectives: The present study was carried out to investigate the effects of Yupoongyangyeong-tang(YYT) on changes of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in rats. In addition, the author also investigated action mechanisms of YYT on changes in rCBF and MABP. Methods and Results : In this study, treatment with YYT elevated rCBF in a dose-dependent manner, but MABP levels were elevated only in the 10 mg/ml treatment group. Pre-treatment with indomethacin. an inhibitor of cyclooxygenase, inhibited increase of rCBF effectively. Pre-treatment with methylene blue, an inhibitor of guanylate cyclase, inhibited increase of rCBF induced by YYT, too. In addition. pre-treatment with indomethacin also inhibited increase of MABP. However, pre-treatment with methylene blue did not affect MABP levels. Conclusion : These results suggest that YYT is useful to treat patients with diseases related to cerebral ischemia, because YYT can increase rCBF. In addition, the mechanisms are thought to be related to both cyclooxygenase and guanylate cyclase.

This experimental studies were done to investigate the effects of Sambutang(SBT) and consitituent herbs on the regional cerebral blood flow(rCBF) and mean arterial blood pressure(BP) in rats. The results are as follows: SBT and consitituent herbs(SBT omitting Zingiberis Rhizoma Recens, Zingiberis Rhizoma Recens. Ginseng Radix and Aconiti iateralis preparata Radix) was increased rCBF significantly in a dose-dependent manner. SBT omitting Zingiberis Rhizoma Recens and Ginseng Radix were decreased significantly BP in rats. But, SBT, Aconiti iateralis preparata Radix and Zingiberis Rhizoma Recens were not affected BP in rats. According to the above findings. it is suggested that SBT causes a diverse response of rCBF, and specially the rCBF by increasing SBT is mediated action of Zingiberis Rhizoma Recens.

In January the clo-values show two characteristic patterns on the insulation, Samjiyon has the highest clo-values while Changjon has the lowest in North Korea, and the coastal areas are lower than in the interior areas. This regional difference is a result of predominant temperature, wind speed and orographic effects. Particularly, in August the coastal areas are generally lower than the interior areas because of orographic effects(wind direction, wind speed). All regions except Samjiyon legions and northern interior regions have low values during the period from the early August to the middle of August. These are largely derived from the stable weather with the highest temperature, humidity and strong radiation by the North Pacific Anticyclone appears in Eastern Asia.

The study was designed to investigate the effects of Leonuri herba extract (LHE) on the change of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats, and further to determine the mechanism of action of LHE. The results in normal rats were as follows, LHE significantly increased rCBF in a dose-dependent manner, and MABP did not change in a dose-dependent manner. This results were suggested that LHE significantly increased rCBF by dilating pial arterial diameter. The LHE-induced increase in rCBF was significantly inhibited by Pretreatment with indomethacin(1 mg/kg, i.p.), an inhibitor of cyclooxygenase, and was significantly inhibited by methylene blue($10{\mu}g/kg$, i.p.), an inhibitor of guanylate cyclase. The LHE-induced MABP did not change by pretreatment with indomethacin but was significantly inhibited by methylene blue. This results were suggested that the mechanism of LHE was mediated by cyclooxygenase.

This study was aimed to investigate the effect Chukdamtanggamibang on the vascular systems including changes in blood pressure and regional cerebral blood flow(rCBF) of male Sprague-Dawely rats, contractile force of guinea pig`s tracheal smooth muscle and abdominal aorta and femoral artery in rabbits. Blood pressure was not affected by Chukdamtanggamibang in rats. rCBF was significantly increased by Chukdamtanggamibang in a dose-dependent manner. Contractile force of isolated guinea pig`s tracheal smooth muscle evoked by His ({TEX}$ED_{50}${/TEX}) were inhibited significantly by Chukdamtanggamibang. Propranolol, indomethacin and methylene blue did not significantly alter the inhibitory effect of Chukdamtanggamibang. Contractile force of isolated rabbit`s abdominal aorta and femoral artery evoked by NE ({TEX}$ED_{50}${/TEX}) were inhibited significantly by Chukdamtanggamibang. ODQ and L-NNA significantly attenuated the inhibitory effects of Chukdamtanggamibang in abdominal aorta, whereas propranolol did not significantly alter the inhibitory effect of Chukdamtanggamibang. These results indicate that Chukdamtanggamibang can relax hitamine-induced contraction of guinea pig`s tracheal smooth muscle and that this inhibition involves, in part, the relation to the soluble guanylyl cyclase synthesis and nitric oxide (NO) synthesis.

This study was performed to provide basic data that predict the application of Saengmaegsan(SMS) as medicinal food. SMS has been used in oriental medicine for many years as a therapeutic agent for cerebral disease. We examined the effects of SMS on physiological function in isolated abdominal aorta and femoral artery from rabbit and measured the changes of regional cerebral hood flow(rCBF), which was continually monitored by laser-doppler flowmeter and pressure transducer in anesthetized adult Spargue-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. The contraction forces by injection of norephinephrine in isolated abdominal aorta and femoral artery were significantly decreased in each concentration of SMS treatment compared with control. rCBF was increased by SMS in a dose-dependent manner. These results suggest that SMS causes a diverse response of rCBF and arterial diameter. These mechanism in rCBF increase may be mediated by prostaglandis, cyclic GMP and adrenergic $\beta-receptor$. Also mechanism in artery contraction decrease is also mediated by prostaglandis and cyclic GMP. These results indicate that SMS can be nsed as a safe and clinically applicable as a supplementation of diet therapy for cerebral cardiovascular disease patients.
