엘리아데는 애초의 성스러움이 저절로 드러나는 것을 성현(聖顯)이라고 하였는데, 성현이 일어나는 대상이나 장소는 질의 전환을 이루어 그 자체가 성스러워진다. 사람들은 태초의 성스러움을 되살리기 위해 최초로 성스러움이 일어난 그 순간을 재현하고자 하여 원형의 순간과 동일한 시간에 동일한 장소에서 동일한 행위를 통해 성을 재현하려고 하였다. 이 논문에서 주목한 것은 성스러움이 드러나는 구체적 장소이다. 천제가 세운 지상의 도읍으로 신이 사는 영역이며, 지상과 천상을 이어주는 역할을 하는 우주산의 특성을 갖춘 곤륜, 하늘과 지상을 이어주는 매개인 하늘사다리의 역할을 하는 건목, 종교적 인간이 성스러운 실재적 공간에서 살고 싶은 욕망을 드러내며 성스러운 공간을 통해 신적 존재나 조상과 교류함으로써 태초의 순수한 영혼으로 회귀할 수 있는 공간인 도시와 종묘는 모두 고대 중국에서 볼 수 있는 성이 드러나는 구체적 공간이라고 할 수 있다.

Photovoltaic (PV) pumping systems with maximum power point tracking (MPPT) technique aims at obtaining the highest possible power to the pump under various insolation and temperature, thus overcomes the mismatch between the photovoltaic panel and the pumping load. A simple method of tracking the maximum power points and forcing the system to operate close to these points is presented in this paper. The MC68HC908GP32 micro control unit (MCU) is employed to implement the proposed MPPT controller. Experimental results will also show the performances of the photovoltaic pumping system with the MPPT technique.

To clarify the distinction between three difference acupoints, the effects of acupuncture on a behavioral performance were evaluated following formalin test. Male Sprague-Dawley rats were used. Each rat received a manual acupuncture at ST36 (zusanli), SP9 (yinlingquan) or BL60 (kunlun) acupoint before formalin injection. The flinching and licking responses were counted by two blinder investigators. The pretreatment of BL60 acupoint was showed significantly inhibition in flinch behavior as compared with control group. These results suggest that acupuncture at BL60 acupuncture may be effective in relieving inflammatory pain.

Acupuncture is the process of stimulating skin regions called meridians or acupoints and has been used to treat pain-related symptoms. However, the pain-relieving effects of acupuncture may be different depending on acupoints. In the present study, the effects of acupuncture on behavioral responses and c-Fos expression were evaluated using a formalin test in male Sprague-Dawley rats in order to clarify the analgesic effects of three different acupoints. Each rat received manual acupuncture at the ST36 (Zusanli), SP9 (Yinlingquan) or BL60 (Kunlun) acupoint before formalin injection. Flinching and licking behaviors were counted by two blinded investigators. Fos-like immunoreactivity was examined by immunohistochemistry in the rat spinal cord. Manual acupuncture treatment at BL60 acupoint showed significant inhibition in flinching behavior but not in licking. Manual acupuncture at ST36 or SP9 tended to inhibit flinching and licking behaviors but the effects were not statistically significant. The acupuncture at ST36, SP9, or BL60 reduced c-Fos expression as compared with the control group. These results suggest that acupuncture especially at the BL60 acupoint is more effective in relieving inflammatory pain than other acupoints.

Background: The vasoreactivity of cerebral artery is currently the subject of increasing interest Transcranial Doppler The purpose of this study was to investigate the analgesic effect of acupuncture in a model of neuropathic pain produced by segmental spinal nerve injury (SSI) in rats. The left L5 and L6 spinal nerves of Sprague-Dawley rats were tightly ligated, and one week later, manual or electro-acupuncture was applied for 30 minutes to the contralateral hindlimb (right side) while the animal was lightly anesthetized with halothane. The mechanical threshold of the paw for ipsilateral (left side) hind limb flinching was determined prior to and 0.5, 1, 2, 4, and 24 hours after termination of acupuncture. The mechanical threshold for flinching was significantly elevated for about 4 hours after manual acupuncture applied to the BL. 60 (Kunlun) point or electro-acupuncture to the BL. 60 and BL. 40 (Weizhong) points. However, manual acupuncture applied to the ST. 36 (Zusanli) point was not effective. Furthermore, systemic naloxone pretreatment had no effect on the acupuncture induced threshold elevation. These data suggests that acupuncture produces a point specific, naloxone independent analgesia in a rat neuropathic pain model. ※ This paper is supported by a grant from the '1996 Jusan Foundation of Wonkwang university.)

The archaeological remnants of coastal ports and shipwrecks serve as invaluable heritage sites that provide profound insights into historical maritime activities conducted by humans. Cross-regional voyages occurred as early as the beginning of the first millennium, aided by the increasing knowledge of the monsoons. Along with expanding intra- and inter-sailing routes, the improved seaworthiness of vessels facilitated the movement of people and seaborne commodities. The names of the Indic, Kunlun, and Persian ships appear in various historical accounts written in the latter half of the first millennium, and the structural details and characteristics can be physically examined by looking at shipwrecks. Southeast and East Asian shipwrecks from the eighth to the fourteenth century provide a perspective on the dynamism of types of seagoing ships involved in long-distance trade. By examining the remnants of cargo being transported by these ships, we begin to understand how the system of cross-regional shipment of heavy and bulky items, metal objects, fragrant woods, glass, and ceramics sustained and impacted the religions, societies, culture, and regional economies. Furthermore, it helps define the Maritime Silk Route heritage to be managed and protected. As such, this paper gives the archaeological evidence of port ruins and wrecks and also introduces, as an example, a case from Central Vietnam.

Supplement of dietary fibers (DF) is regarded as one of the most effective way to prevent and relieve chronic diseases caused by long-term intake of a high-fat diet in the current society. The health benefits of soluble dietary fibers (SDF) have been widely researched and applied, whereas the insoluble dietary fibers (IDF), which represent a higher proportion in plant food, were mistakenly thought to have effects only in fecal bulking. In this article, we proved the anti-obesity and glucose homeostasis improvement effects of IDF from pear pomace at first, and then the mechanisms responsible for these effects were analyzed. The preliminary study by real-time PCR and ELISA showed that this kind of IDF caused more changes in the gut microbiota compared with in satiety hormone or in hepatic metabolism. Further analysis of the gut microbiota by high-throughput amplicon sequencing showed IDF from pear pomace obviously improved the structure of the gut microbiota. Specifically, it promoted the growth of Bacteroidetes and inhibited the growth of Firmicutes. These results are coincident with previous hypothesis that the ratio of Bacteroidetes/Firmicutes is negatively related with obesity. In conclusion, our results demonstrated IDF from pear pomace could prevent high-fat diet-induced obesity in rats mainly by improving the structure of the gut microbiota.

Objectives : The mesolimbic dopamine system is believed to play a major role in the reinforcing effect and behavioral hyperactivity of abused drugs including methamphetamine. In the present study, the effect of acupuncture on methamphetamine-induced locomotor activity and c-Fos expression in the striatum and nucleus accumbens of rats were examined. Methods : Male Sprague-Dawley rats received acupuncture at bilateral Yanggu($SI_5$) point for 30seconds immediately before the subcutaneous injection of saline or methamphetamine(0.5mg/kg). The total amount of locomotor activity for 90min were measured just before brain samples were taken for immunohistochemistry. Results : Results showed that acupuncture at the specific point $SI_5$, but not control point(Kunlun, $BL_{60}$) significantly reduced locomotor activity and c-Fos expression in the striatum and nucleus accumbens induced by acute administration of methamphetamine. Conclusions : These results suggest that acupuncture may be effective in suppressing the reinforcing effect of methamphetamine by regulating neuronal activity.

Objective: There are currently no disease-modifying medications or definite long-term sustainable interventions for patients with Parkinson's disease (PD), indicating an unmet treatment need. Our goal was to create a long-term sustainable intervention for PD patients that can be used in Korean medicine clinics. Methods: The Meridian Activation Remedy System (MARS) was created to stimulate a patient's 12 meridians and sinew channels using a combination of acupoint stimulation and exercise. The acupoints and motions used in MARS were selected through literature studies and expert advice. The methodologies were refined using observational and case studies. With slow and fast movements, the MARS intervention was intended to activate both slow- and fast-twitch muscle fibers. Intradermal acupuncture and motion that shift the center of gravity were employed to enhance the patient's balance and proprioception. In addition, the intervention included alternating movement exercises to address the complex cognitive decline commonly occurring in PD patients. Results: The following acupoints were chosen for the MARS intervention: bilateral Hegu (LI4), Houxi (SI3), Waiguan (TE5), Neiguan (PC6), Zhongchong (PC9), Yuji (LU10), Zusanli (ST36), Yanglingquan (GB34), Taichong (LR3), Kunlun (BL60), and Taixi (KI3). We also developed actions that can stimulate the body's 12 meridians. Conclusion: We developed the MARS intervention, which combines acupuncture and exercise, to address the unmet therapeutic needs of PD patients. We hope that with additional research, the MARS intervention can be set as an effective therapeutic program for PD patients.

In this study, we introduce a canonical correlation analysis method to accurately assess the tunnel damage potential of ground motion. The proposed method can retain information relating to the initial variables. A total of 100 ground motion records are used as seismic inputs to analyze the dynamic response of three different profiles of tunnels under deep and shallow burial conditions. Nine commonly used ground motion parameters were selected to form the canonical variables of ground motion parameters (GMP_CCA). Five structural dynamic response parameters were selected to form canonical variables of structural dynamic response parameters (DRP_CCA). Canonical correlation analysis is used to maximize the correlation coefficients between GMP_CCA and DRP_CCA to obtain multivariate ground motion parameters that can be used to comprehensively assess the tunnel damage potential. The results indicate that the multivariate ground motion parameters used in this study exhibit good stability, making them suitable for evaluating the tunnel damage potential induced by ground motion. Among the nine selected ground motion parameters, peck ground acceleration (PGA), peck ground velocity (PGV), root-mean-square acceleration (RMSA), and spectral acceleration (Sa) have the highest contribution rates to GMP_CCA and DRP_CCA and the highest importance in assessing the tunnel damage potential. In contrast to univariate ground motion parameters, multivariate ground motion parameters exhibit a higher correlation with tunnel dynamic response parameters and enable accurate assessment of tunnel damage potential.
