Oxygen deficiency has been frequent in a clouted space. Wood consumes oxygen and discharges carbon dioxide Instead of photosynthesis in closed space without light, so do some microorganisms on the surface. We experienced a case that a healthy Insect-proofer fell down and died of asphyxia on stair-board at 7 m below the hatch of the cargo-hold shipping wood Analysis of gases in cargo-hold revealed O2; 12.3%, CO; 105 ppm, CH4; 2.7%, and H2S; 1.9% at 1 m below the hatch, and then O2; 6.1%, CO; 220 ppm, CH4; 2.9%, and H2S, 2.3 ppm at 2.5 m below the hatch. Autopsy findings were unremarkable. We justiced the cause of death asphyxia due to oxygen deficiency. As seen in this case, the serious oxygen deficiency was accounted for oxygen consumption by wood and microorganisms.

연구목적: 본 연구는 여성노인을 대상으로 저항운동 시 사용되는 set구성 방법에 중 ascending set, descending set, drop set를 각각 적용시켜 Myokine의 변화를 알아보고자 하였다. 연구방법: 연구대상은 노인복지시설을 이용하고 있는 만 65-72세 사이의 여성노인 32명을 대상으로 ascending set, 8명, descending set 8명, drop set 8명, control group 8명으로 구분하였다. 자료처리는 반복측정에 의한 이원변량분석(two-way ANOVA with repeated measure)을 사용하였으며, 유의도는 .05로 하였다. 결론: 운동프로그램은 12주간 주 3회 실시하였으며, 신체구성과 IL-15, BDNF, VEGF, Irisin의 변화를 관찰하였다. 연구결과 신체구성의 체중, 체지방률, 제지방량 모두 유의한 차이가 없었다. IL-15와 BDNF는 운동 전·후의 비교결과 Descending set와 Drop set에서 운동 후 유의하게 증가하였고, 집단 간의 차이에서 Descending set와 Drop set 집단이 대조집단에 비하여 높게 나타났다. VEGF는 운동 전·후의 비교결과 Descending set와 Drop set 집단이 유의하게 증가하였으며, 집단 간의 차이에서 Descending set와 Drop set가 Ascending set와 control group 보다 높게 나타났다. Irisin은 집단 간 차이는 없었지만 Ascending, Descending, Drop set집단에서 운동 전에 비하여 운동 후 유의한 차이로 증가하였다.. Purpose: The purpose of this study is to identify the change of Myokine by applying ascending set, descending set, and drop set which are set composition used during elderly women’s resistance training. Method: 32 participants aged 65 to 72 who were users of welfare facilities for the aged were divided into 4 groups. They were ascending set group of 8, descending set group of 8, drop set group of 8, and control group of 8. The training program was conducted 3 times a week for 12 weeks and the change of body composition, IL-15(interleukin-15), BDNF(brain derived neurotrophic factor), VEGF(Vascular endothelial growth factor) and Irisin was observed. Two-way ANOVA with repeated measure was used for data processing. Result: The result of this study is as follows. Weight, %fat, and LBM(lean body mass) without fat showed no significant change. IL-15 and BDNF increased significantly after training in Descending set group(p<.05; p<.01)and Drop set group(p<.01; p<.05). VEGF significantly increased in descending set group(p<.01) and drop set group(p<.05). Among groups, VEGF was higher in descending set and drop set groups than ascending set and control groups. Irisin showed no difference between groups, but it showed significant increase after training in ascending(p<.05), descending(p<.05), and drop set groups(p<.05).

捻轉法이 竝行된 鍼刺戟 및 電鍼刺戟이 鎭痛效果에 미치는 影響

Park, Dong-Seok,Kim, Ji-Hoon,Min, Byung-Il,Oh, Soo-Myung 경희대학교 동서의학연구소 1999 INTERNATIONAL SYMPOSIUM ON EAST-WEST MEDICINE Vol.1999 No.1

Dong-Seok Park¹, Ji-Hoon Kim¹ and Byung-Il Min, Soo-Myung Oh,³¹Department of Acupuncture and Moxibustion, College of Medicine, ²Department of Physiology, College of Medicine, And ³East-West Medical Research Institute, Kyung Hee University,Seoul, Korea. Analgesic Effect of Manual Acupuncture and Electroacupuncture combined with Twirling Method. Proceeding of International Symposium on East-West Medicine Seoul. 187-200, 1999.-Twirling the needle (TN) is one of several needing methods frequently used for acupuncture in the oriental medicine. The present study was conducted to see if TN enhanced the antinociceptive effect produced by plain-or electroacupuncture in the rat tail flick test. Rats (Sprague-Dawley, 200-300g)lightly anesthetized with thiopental sodium(40mg/kg, i.p.) were used in the tail-flick test. The basal reaction time for tail-flick was 2 sec. For "plain" acupuncture(PA), a needle was inserted for 20 min into a Chock-samni (ST36) acupuncture point which (is located at the anterior tibial muscle and about 10mm below the knee joint). For electroacupuncture(EA), train-pulses(3 Hz,0.3-ms pulse width, 0.2-0.3mA) were applied to the inserted needle for the period of insertion. For combining TN with either PA or EA, TN was performed during the each acupuncture period. Two methods for TN were used; twirling 3 times for 1 second persisted for 1 min in every 5 mins(long-duration and long-interval;LDLI) and twirling 3 times for 1 second persisted for 10 sec in every 1 min(short-duration and short-interval;SDSI). PA and EA produced an increase in tail flick latency (TFL); peak increases were 21.3±5.1% and 42.1±17.3% of the pre-acupunture control, respectively, and occurred immediately after cessation of 20min-acupuncture. Performing TN combined with PA increased TFL more than PA itself by showing a greater peak increase in TFL when performed with a SDSI-TN than with a LDLI-TN(60.6±12.5% and 42.7±22.7% of the pre-acupuncture control, respectively). Performing TN combined with EA also increased TFL more than EA itself and a greater peak increase in TFL was observed with a SDSI-TN as compared to a LDLI-TN(77.5±13.8% and 67.3±14.0% of the pre-acupuncture control, respectively). These results indicate that TN enhances both PA-and EA-produced antinociception where an greater enhanced antinociception than a LDLI-TN. It is suggested that performing a SDSI-TN combined with EA seems to be one of the most effective ways to produce analgesia.

Apoptotic Effect of Co-treatment with Chios Gum Mastic and HS-1200 on G361 Human Melanoma Cell Line

Young-Joo Hur,Young-Ki Kim,Hyun-Ho Kwak,Gyoo-Cheon Kim,Seung-Eun Lee,In-Ryoung Kim,Chul-Hoon Kim1,Bong-Soo Park 대한해부학회 2009 Anatomy & Cell Biology Vol.42 No.2

Chios gum mastic (CGM) is a resinous exudate obtained from the stem and the main leaves of Pistacia lenticulus tree native to Mediterranean areas. Recently it reported that CGM induce apoptosis in a few cancer cells in vitro. Bile acids and their synthetic derivatives induced apoptosis in various kinds of cancer cells and anticancer effects. It has been reported that the synthetic chenodeoxycholic acid (CDCA) derivatives showed apoptosis-inducing activity on various cancer cells in vitro. This study was undertaken to investigate the synergistic apoptotic effect of cotreatment with a natural product, CGM and a CDCA derivative, HS-1200 on G361 human melanoma cells. To investigate whether the co-treatment of CGM and HS-1200 compared with each single treatment efficiently reduced the viability of G361 cells, MTT assay was conducted. To investigate augmentation of apoptosis in G631 cells co-treated with CGM and HS-1200, DNA electrophoresis, Hoechst staining, proteasome activity assay, flow cytometry, Westen blot analyses, immunofluorescent staining and confocal microscopy were performed. In this study, G361 cells co-treated with CGM and HS-1200 showed several lines of apoptotic manifestation such as nuclear condensations, DNA fragmentation, the reduction of MMP and proteasome activity, the decrease of DNA content, the release of cytochrome c into cytosol, the translocation of AIF and DFF40 (CAD) onto nuclei, activation of caspase-9, caspase-3, PARP and DFF45 (ICAD), and up-regulation of Bax whereas each single treated G361 cells did not. Although the single treatment of 40 μg/mL CGM or 25 μM HS-1200 for 24 hrs did not induce apoptosis, the co-treatment of them induced prominently apoptosis. Therefore, combination therapy of CGM and HS-1200 could be considered, in the future, as an alternative therapeutic strategy for human melanoma.

醫藥品의 安定性에 關한 硏究 (第3報) : Sulpyrin 水溶液의 安定性에 關하여 The Stability of Sulpyrin in Aqueous Solution

金鍾秀,金壽億,徐成勳 慶熙大學校 1983 論文集 Vol.12 No.-

The pharmacokinetic study of solution was conducted to determine the stability of sulpyrin. The powder was added with diluents and stored under three different conditions to determine the humiditification weight and degradation rate. The solution of sulpyrin indicated first order reaction and t_90 was 82 days at 25℃. When the powder was stored under the three different conditions, the avicel mixture showed the highest humiditification weight, while the only sulpyrin showed the highest degradation rate under the relative humidity of 75% and 92% followed by the avicel mixture. The starch and lactose mixture showed the lowest similar humiditification weight and degradation rate. Therefore, it seems that the stability of the main ingredient will be greatly influenced by the diluents.

甲殼類의 分類學

金熏洙 全北大學校 生物學硏究所 1981 生物學硏究年報 Vol.2 No.-

甲殼類(Crustacea)는 절지동물의 한 綱 또는 上綱인데, 이것은 무척추동물 중에서 가장 크고 또, 가장 다양한 무리들 중의 하나이다. 많은 종류의 새우류ㆍ게류가 경제적으로 중요하다는 것이 옛날부터 인식되어 왔고, 육수학자들은 작은 갑각류의 무리들이 호수나 계류의 생태계에 공헌하는 바가 크다는 것을 인색해 왔으며, 어업 생물학자들은 많은 종류의 부유성 갑각류가 어류의 먹이사슬에 중요한 구실을 한다는 것을 알게 되었다. 최근에는 저서생물 생물학자들과 생태학자들은 광범위한 저서성 갑각류가 군집 내부의 영양 단계와 에너지 순환에 절대 필요한 구실을 다하고 있다는 것을 발견해 왔다. 이렇게 갑각류는 매우 중요한 분류군이라고 할 수 있다.

RSC-300을 이용한 음성인식 시스템 구현

김수훈,안종영 부천대학 2002 論文集 Vol.23 No.-

본 논문에서는 Sensory사의 RSC-300을 이용하여 음성인식 시스템을 구현하였다. RSC-300은 음성 입력 시 이득조절이 가능한 프리앰프를 내장하고 있으며, 8비트 마이크로 컨트롤러를 탑재한 전용 칩으로 인식모델로 신경망을 이용하고 있다. 실험에서는 음성인식 시스템에서 화자의 음성을 인식하여 포트신호가 IR 컨트롤러를 구동시키고, 컨트롤러는 다시 IR 신호를 출력해 줌으로써 편리하게 제어할 수 있도록 하였으며, 메모리 용량을 고려하여 종속화자의 음성을 2회 학습시켜 사용하였다. 실험결과 80% 이상의 양호한 인식률을 보였으며, 장시간 사용시의 안정성 문제와 오동작에 대한 문제만 해결한다면 실생활에 적용이 가능할 것으로 사료된다. In this paper, we implement the speech recognition system using RSC-300, developed by Sensory Inc. RSC-300 is 8-bit microcontroller featuring 64K of internal ROM, on-chip A/D and D/A converters, 16 general purpose I/O lines, and an on-chip output amplifier. To implement speech recognition system, we used serial EEPROM(24C65) for data memory and Flash(29C20) ROM for program memory. In the experiment, we did the training process 2 times for training data. As a result of experiment, the system has good recognition ability and is expecting to be applied to daily life.
