제조 현장의 센서나 기기들에서 생성된 대량의 데이터들이 서버나 클라이언트로 전송되면서 네트워크 처리시간 지연, 스토리지 자원 비용 증가의 문제가 발생한다. 이러한 문제 해결을 위해 실시간 대응성과 무중단 공정이 필수인 제조 현장을 고려하여 실시간 및 무손실 압축이 가능한 QRC(Quotient Remainder Compression)와 BL_beta 압축 알고리즘을 처음으로 실제 제조 현장 센서 데이터에 적용하여 실험 결과로 두 알고리즘 중 어떤 알고리즘이 성능이 좋은지 비교 분석하였다. 실험 결과는 BL_beta가 QRC보다 압축률이 높았다. QRC의 데이터 크기를 조금 조정하여 동일한 데이터로 실험을 진행한 실험결과는 데이터 크기를 조정한 QRC 알고리즘이 기존 QRC와 BL_beta 압축 알고리즘보다 압축률이 35.48%, 20.3% 더 높았다.

Many dinoflagellates produce bioluminescence. To estimate the intensity of bioluminescence produced by populations of the heterotrophic dinoflagellates Noctiluca scintillans and Polykrikos kofoidii and autotrophic dinoflagellate Alexandrium mediterraneum in Korean waters, we measured cellular bioluminescence intensity as a function of water temperature and calculated population bioluminescence intensity with cell abundances and water temperature. The mean 200-second-integrated bioluminescence intensity per cell (BL_cell) of N. scintillans satiated with the chlorophyte Dunaliella salina decreased continuously with increasing water temperature from 5 to 25℃. However, the BL_cell of P. kofoidii satiated with the mixotrophic dinoflagellate Alexandrium minutum continuously increased from 5 to 15℃ but decreased at temperatures exceeding this (to 30℃). Similarly, the BL_cell of A. mediterraneum continuously increased from 10 to 20℃ but decreased between 20 and 30℃. The difference between highest and lowest BL_cell of N. scintillans, P. kofoidii, and A. mediterraneum at the tested water temperatures was 3.5, 11.8, and 21.0 times, respectively, indicating that water temperature clearly affected BL_cell. The highest estimated population bioluminescence intensity (BL_popul) of N. scintillans in Korean waters in 1998-2022 was 4.22 × 10¹³ relative light unit per liter (RLU L^-1), which was 1,850 and 554,000 times greater than that of P. kofoidii and A. mediterraneum, respectively. This indicates that N. scintillans populations produced much brighter bioluminescence in Korean waters than the populations of P. kofoidii or A. mediterraneum.

Objectives : There has been a need for developing and establishing operational curriculum for the education of acupuncture, but defining the level and step of the acupuncture education in clinical perspectives was not thoroughly recognized so far. Methods : We analysed the usage of acupuncture points in the official textbook to recognize the most frequently used acupoints in clinical medicine. It was found that $ST_{36}$ $LI_4$ $SP_6$ $HT_7$ $LR_3$ $CV_{12}$ $BL_{23}$ $CV_6$ $BL_{20}$ $CV_4$ $LI_{11}$ $PC_6$ $KI_3$ $GB_{20}$ $GV_{20}$ $GB_{34}$ $BL_{18}$ $GV_{14}$ $BL_{17}$ $BL_{40}$ are the most frequently used 20 acupuncture points and GB(足少陽擔經), CV(任脈), ST(足陽明胃經) are the most frequently used meridians. Results : The $ST_{36}$, $GB_{34}$, $LI_{11}$ and GB(足太陽膀胱經) meridian are most frequently used for muskuloskeletal disease, $ST_{36}$, $LI_4$, $LI_{11}$ and GB(足太陽膀胱經) meridian are most frequently used for neuromuskular disease, and $ST_{36}$, $CV_{12}$, $BL_{20}$ and CV(任脈) meridian are most frequently used for the digestive system disorders. Conclusions : This study was the first systematic approach to get essential acupuncture points for the education of clinical perspectives of TKM especially for the acupuncture and moxibustion. We found that the $ST_{36}$, $GB_{34}$, $LI_{11}$ and GB(足太陽膀胱經) are the most frequently used acupuncture point and meridian. This study will be used for the development of TKM clinical curriculum.

Objective : The purpose of this study is To investigate the effects of acupuncture and moxibustion at Zusanli(ST36) and Weishu(BL21) Methods : serum gastrin level by radioimmunoassay was measured at 5 days after acupuncture and moxibustion of those acupoints. Gastric endocrine cell(G cell and Histamine immunoreactive density) by avidin-biotinylated complex(ABC) technique, histological examinations(Alcian Blue-PAS Stain; Alcian blue-Periodic Acid Schiff reagent) of the gastric mucosa were also performed. Acupuncture applied to the ST36 acupoint increased gastrin level of serum, but moxibustion did not produced significant effect. All of acupuncture and moxibustion at BL21 acupoint increased gastrin level of serum significantly. In moxibustion at ST36 and BL21, the number of gastrin secreting cells in gastric mucosa, the density of immunoreactive histamin secreting cells and the density of body mucosa stained by PAS were decreased compare to acupuncture at ST36 and BL21. In acupuncture and moxibustion at BL21, the density of pylorus mucosa stained by PAS were increased compare to the groups applied to ST36. In the density of body mucosa stained by AB, moxibustion at BL21 and ST36 were increased compare to the other groups. Results : These data suggest that acupuncture and moxibustion at BL21 increased gastrin level of serum and those effects were more potent than acupuncture at ST36.

This study was performed to elucidate the effect of acupuncture and aqua-acupuncture in dogs. Each group was divided into control (18 dogs), PC-6 (6 dogs) and BL-21 (6 dogs) group for the antiemetic effect of acupuncture, respectively. And, the animals were divided into control (18 dogs), PC-6 (18 dogs) and BL-21 (18 dogs) group for the antiemetic effect of aqua-acupuncture with metoclopramide, respectively. 2% xylazine was injected to the all dogs to induce the emesis, and acupuncture and aqua-acupuncture treatment (0.5% metoclopramide) were applied to animals for 20 min. before xylazine injection, respectively. Emetic rates in PC-6 (33.3%) and BL-21 (16.7%) were lower than that of control group (44.4%) in acupuncture groups, respectively. Emetic rates in PC-6 (16.7%) and BL-21 (0.0%) were lower than that of control group (38.9%) in aqua-acupuncture groups, respectively. Based on these findings, it was considered that the antiemetic effects of acupuncture and aqua-puncture at BL-21 were more effective than those of PC-6 groups, and aqua-acupuncture with metoclopramide at BL-21 was the most effective among them.

We present observations of $HCO^+$ 1-0 absorption lines toward two extragalactic compact radio sources, NRAO 150 and BL Lac with the Korean VLBI Network in order to investigate their time variation over 20 years by Galactic foreground clouds. It is found that the line shape of $-17kms^{-1}$ component changed marginally during 1993-1998 period and has remained unaltered thereafter for NRAO 150. Its behavior is different from that of $H_2CO$ $1_{10}-1_{11}$, suggesting chemical differentiation on ~ 20 AU scale, the smallest ever seen. On the other hand, BL Lac exhibits little temporal variation for the $HCO^+$ and $H_2CO$ lines. Our observation also suggests that Korea VLBI Network performs reliably in the spectrum mode in that the shapes of the new $HCO^+$ 1-0 spectra are in good agreement with the previous ones to an accuracy of a few percent except the time varying component toward NRAO 150.

To determine whether bile juice exclusion can prevent the mucosal damage, and Insulin-like growth factor-I can promote mucosal regeneration in ischemia-reperfusion injury of the bowel, 39 weanling rats with 10 cm of Thiry-Vella loop were studied. Animal groups were; Control, BL(common bile duct ligation), IGF{insulin-like growth factor-I(IGF-I) infusion} and IGF-BL(combined treatment). IGF-I(1.5 mg/kg/day) was continuously delivered through a subcutaneously implanted miniosmotic pump. After 15 minutes of superior mesenteric artery clamping, a tissue specimen(P) was taken after 30 minutes of reperfusion. Intestinal continuity was restored to allow oral feeding. A specimen of main tract(M) and another of the Thiry-Vella loop(T) were collected for histomorphometry after 48 hours of reperfusion and free feeding. Villus size ratio(VSR), crypt depth(CD), crypt-depth/villus-height ratio(CVR) and injury score(IS) were measured in 15 consecutive villi. The postoperative mortalities of bile duct ligation groups(BL and IGF-BL) were higher than those of other groups. In control group, VSR of M was lower(P<0.05) than P or T, but not in the other groups. VSR of M in control was lower than those in other groups. CD of T in control, IGF and IGF-BL group were higher than those of M. CD of M and T showed gradual increments from control, IGF and IGF-BL group, respectively. CVR of M and T in IGF group were higher than those in control. CVR in IGF-BL group, T was higher than M, and M was higher than P. About IS, M of BL($20.1{\pm}2.5$) and IGF-BL($20.9{\pm}3.3$) groups were significantly lower than that of control($32.4{\pm}2.5$). These results suggest that the exclusion of bile juice reduces the severity of the reperfusion injury of the mucosa, by inability to activate pancreatic enzymes and IGF-I stimulates mucosal regeneration in injured bowel, and the effect is potentiated by bile juice exclusion.

Background & Objective: Regardless of types of cancer, cancer pain means the pain occurred by tumor itself, caused by complication or side effects during treatment and which is neither directly related to tumor nor treatment. This case was performed to relieve the cancer pain and study the effect of moxibustion to the cancer pain. Method: For 27 days, the patient was treated by moxibustion($MANINA^{(R)}$), acupuncture, herbal medicine and narcotic analgesics. We planned to maintain moxibustion on 8 points of Bladder meridian line(BL13, BL17, BL42, BL43) for 20 minutes. The improvement of the symptom was evaluated by BPI/VAS, and the amount of narcotic analgesics applied. Results: The BPI/VAS was declined and amount of applying narcotic analgesics was decreased. Conclusion: It is suggested that moxibustion on BL13, BL17, BL42, BL43 is useful to relief of cancer pain in left flank area.
