Single crystals of sapphire were grown from solution by slow cooling method using B2O3 and PbO as flux agents. The morphology of grown crystals was tube, rhombohedral, or hexagonal-plate. It was found that the morphology and the size of grown crystal were highly dependent on the amount of fluxes in the solution, the ratio of B2O3 vs. PbO, and cooling rate.

조병곤,오근호 한국세라믹학회 1990 한국세라믹학회지 Vol.27 No.4

ZnWO4 single crystals were grown by Czochralski method. And the orientation of grown crystals were determined by Laue back reflection, and the crystals were siliced at (100), (010), (001) face before polishing. The morphologys and distribution of etch pits on each face were observed by optical microscopy. In the present study, we understood that dislocation distributjioon rely on shape of solid-liquid interface, and secondary phase acts on the dislocation source. We also observed dislocation trace(etch pits) of (100) slip plane on (010) cleavage plane.

Sympathetic Nervous Activity is Involved in the Anti-Inflammatory Effects by Electroacupuncture Stimulation

조병곤,김남훈,남궁욱 경락경혈학회 2019 Korean Journal of Acupuncture Vol.36 No.3

Objectives : Increasing evidence suggests that parasympathetic vagus nerve activity plays a role in modulating acupunctureinduced anti-inflammatory reaction, but the function of sympathetic nerve is not known. Here, we investigated whether splanchnic sympathetic nerve activity was involved in the regulation of splenic expression of TNF-α mRNA by electroacupuncture (EA) in LPS-injected animals. Methods : DiI was injected into the stomach or celiac ganglion (CG) for retrograde labeling of the target tissues. EA was given at ST36 and the electrical stimulation on the sciatic nerve in LPS-injected mice. c-Fos signals in the tissues were analyzed by immunofluorescence staining, and TNF-α mRNA was analyzed by real-time PCR. Results : Application of EA at ST36 or electrical stimulation on the sciatic nerve induced c-Fos expression in neurons of the spinal cord and celiac ganglion (CG). Then, the vagotomy reduced c-Fos levels in CG neurons but not in the spinal cord in animals given EA. Expression of TNF-α mRNA which was induced in the spleen after LPS was significantly inhibited by EA, then the vagotomy elevated TNF-α mRNA level similar to that in LPS-injected animals. Splanchnectomy in animals given LPS and EA also increased TNF-α mRNA though it was less effective than vagotomy. Conclusions : Our data suggest that EA delivered to the spleen via the splanchnic sympathetic nerve may be involved in attenuating splenic inflammatory responses in LPS-injected animals.

장용우, 김성철, 조병곤, 이하얀, 김동희, 김용규, 권양기. 운동과학, 제11권 제1호, 93-104, 2002. 본 연구는 국소 골격근 수축시 혈류 및 산소운반 변인의 변화를 분석하기 위하여 중량운동으로 단련된 선수군과 일반학생 등 총 18명을 대상으로 상완이두근의 반복적 최대 굴신전 운동틀 통해 운동 전, 후 및 회복기 혈류변인인 최대혈류속도(PBV), 평균혈류속도(MBV)와 산소운반변인인 RBC, Hb, Hct, Myoglobln 등을 측정 분석한 결과 국소적 골격근 수축시 PBV의 경우 선수군은 운동직후 85.0%로 비교군 96.3%에 비해 유의하게 낮은 증가율을 나타냈고, 회복시에는 선수군이 비교군 -16.0%에 비해 -40.2%로 유의하게 높은 회복비를 나타냈다. MBV는 선수군의 경우 운동직후 131.8%로 비교군 154.1%에 비해 유의하게 낮은 증가율을 나타냈고, 회복시에는 선수군이 비교군 -24.3%에 비해 -50.5%로 유의하게 높은 회복비를 나타냈다. 국소적 골격근 수축시 RBC의 경우 운동직후 7.5%로 비교군 6.9%에 비해 유의하게 높은 증가율을 나타냈고, 회복시에는 선수군이 비교군 -5.9%에 비해 -4.8%로 유의하게 높은 회복비를 나타냈다. Hb의 경우 선수군은 운동직후 10.7%로 비교군 8.2%에 비해 유의하게 높은 증가율을 나타냈고, 회복시에는 선수군이 비교군 -7%에 비해 -11.4%로 유의하게 높은 회복비를 나타냈다. Hct의 경우 선수군은 운동직후 8.8%로 비교군 9.1%와 별다른 차이가 없었으나, 회복시에는 선수군이 비교군 -7.7%에 비해 -4.5%로 유의하게 높은 회복비를 나타냈다. Mgb의 경우 선수군온 운동직후 -21.2%로 비교군 -14.2%에 비해 유의하게 높은 감소율을 나타냈고, 회복시에는 선수군이 비교군 -23.1%에 비해 -12.6%로 유의하게 높은 회복비를 나타냈다. 따라서 국소 골격근의 반복적인 근수축시 혈류변화는 안정시 비활동근에 비해 운동근으로 유입되는 혈류의 정확한 이동속도와 활동근의 산소소모에 따른 운반변인의 유동성을 확인할 수 있었으며, 추후 측정부위가 달리된 혈류검사를 통해 혈관계 질환의 임상적 운동 검사 및 처방에 그 적용폭을 넓혀 모색해야 할 것으로 사료된다. Jang Y.W, Kim, S.C., Cho, B.K., Lee, H.Y., Kim, D.H. Mm, Y.K., & Kwon, Y.K. The Change of Artery Blood Velocity and Oxygen Transfer System at Partial Musculoskeletal Contraction. Exercise Science, 11(1): 99-104, 2002. The purpose of this study is to exanine the change of oxygen transfer system when partial musculoskeletal contracticn. The participants for this study consist of 18 subjects and into two groups, which are experiment group compose of dumbell exercise trained sports players and control group that has not took part regularly in sport activity for a minimum of 3 times per week. They are measured blood velocity factors of PBV, MBV and oxygen transfer factors of RBC, Hb, Hct, Myoglobin by pre-post, recovery exercise through maximum extension and flexion movement of bioeps branchii. The result are as following: In the case of PBV when partial musculoskeetal systolic, the experiment group(85.0%) has shown significantly lower rates of increase than control group(96.3%) in the pre-post exercise, and experiment group(40.2%) has shown significantly higher rates of recovery than control group(-16.0%) in the recovery. In the case of MBV, the experiment group (13.18%) has shown significantly lower rate of increase than control group(15.41%) in the pre-post exercise, and experiment group(-50.5%) has shown significantly higher rates of recovery than control group(-24.3%) in the recovery. In the case of RBC when partial musculoskeletal systolic, the experiment group(6.9%) in the pre-post exercise and the experiment group(-5.9%) has shown significantly higherrates of recovey than control group(-4.8%) in the recovery. In the case of Hb, the experiment group (10.7%) gas shown significantly higher rates of increase than control group(8.2%) in the pre-post exercise, and the experiment group(-11.4%) has shown significantly higher rates of recovery than control group(-7%) in the recovery. In the case of Hct, there are no significantly relationship between experiment group(8.8%) and control group(9.1%) in the pre-post exercise, and the experiment group(-7.7%) has shown significantly higher rates of recovery than control group(-4.5%) in the recovery, In the case of Mgb, the experiment group(-21.2%) has shown significantly higher rates of increase than control group(-14.2%) in the pre-post exercise, and the experiment group(-12.6%) has shown significantly higher rates of recovery than control group(-23%) in the recovery. Therfore, blood flow change at repetition muscle contraction of partial musculoskeletal was confirmed to correct a mobile velocity of blood flow an influx to exercise muscle as compared with inactivity muscle at rest and to fluctuation of transport variation according to O_2 consumption of activity muscle, it will selected adaption to clinic exercise test and prescription of vascular disease according to blood flow test in a different way measurement position..

The study was to investigate the effect of 10 days bicycle tour on the change of hormone(cortisol, testosterone) and enzyme (CPK, LDH), Twenty subjects were divided into the tour group and the control group. The tour group performed 10 days bicycle tour of 1250km distance. After extracting the blood sampling at pre and post of tour, the change -of hormone and enzyme were compared between the groups. The 2(pre & post)×2(tour & control group) two way ANOVA was used. The results obtained from this study were as follows; After 10 days tour, CPK was showed significant difference between groups(p$lt;.01). And cortisol of the control group was changed significantly(p$lt;.01) in time(pre & post) and interaction. T/C ratio showed significantly in interaction(p$lt;.05). But LDH and testosterone were showed no significant difference between groups and pre & post time series.
