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).

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.

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.

This study was intended to raise solids yield in the sea tangle extract. Sea tangle extracted by additions of acetone, methyl alcohol, isopropyl alcohol and ethyl alcohol. Among four solvents used for sea tangle extraction, the optimal solvent was ethyl alcohol. The most appropriate method of sea tangle extraction was two-stage extraction, that extracted with addition of ethyl alcohol and residue was extracted with water(1:13, w/v). As the optimal conditions of ethyl alcohol were 25℃ and 70%, respectively. The basis of solids yield in sea tangle extract, optimal extracting time was about 1 hour. The yield of soluble solids under above-mentioned conditions was 18.2%. Drinking product was made by adding 0.1% citric acid, 2% sorbitol and 2% oligosaccharide to the sea tangle extract(Brix 10).

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.

김영신,박애련,임수민,정재훈,김수완,송하영 경북대학교 과학교육연구소 2009 科學敎育硏究誌 Vol.33 No.1

Probabilistic reasoning and combinational reasoning are essential to build a logical thinking and a process of thinking dealing with everyday life as well as scientific knowledge. This research aims at finding the optimal period to teach reasoning to the students who haven't developed probabilistic reasoning and combinational reasoning. The treatment program was performed for 20 students from each grade who couldn't develop two parts of reasoning. The treatment program using baduk stones and cards was performed repeatedly, focusing on the specific activities. After four weeks of treatment program, the test to check the development of probabilistic reasoning and combinational reasoning was performed again and the changes of reasoning development were identified. After giving treatment program for reasoning development, 15.0%, 25.0% and 40.0% of improvement in the 4th, the 5th, the 6th graders respectively were shown. With regard to the combinational reasoning, the results showed the improvement of 20.0% in the 4th grades, 25.0% in the 5th graders and 63.2% in the 6th graders. As a result of research in the above, students, who were not formed probabilistic reasoning and combinational reasoning, could be known to be enhanced through learning, but to fail to be formed the qualitative change like the cognitive development. It is expected that this research can contribute to the improvement of students' cognitive level and there would be more active researches in different fields to improve the cognitive level of the 6th graders who are in their optimal periods to learn two parts of reasoning. 이 연구의 목적은 확률 논리와 조합 논리가 형성되지 않은 학생들에게 논리 지도를 위한 최적의 시기를 찾고자 하는 것이다. 초등학교 4, 5, 6학년 학생 430명을 대상으로 논리의 형성정도를 사전에 검사하였다. 검사도구는 GALT를 참고하여 개발하였고, 이는 과학 교육 전문가에게 타당도를 검증 받았다. 처리프로그램은 두 가지 논리가 모두 형성되지 않은 각 학년 20명의 학생을 대상으로 수행하였다. 이는 바둑돌과 카드를 반복적으로 수행하는 검사도구이다. 4주 뒤 사후검사에서 확률논리와 조합논리의 발달정도를 알아보는 검사를 다시 수행하였고 그 변화는 확인되었다. 확률논리의 경우 4, 5, 6학년에서 형성율이 각각 15%, 25%, 40% 증가하였고, 평균도 .15, .30, .50 증가하였다. T-검증에 의한 의미있는 결과는 6학년 중에서 얻어졌다. 그러나 과도기 학생 비율(21.7%)를 제외하면 형성 학생의 비율은 5.0%로 여전히 저조하였고, 다수의 학생(73.3%)은 미형성 상태를 유지하였다. 조합논리의 경우 4, 5, 6학년에서 형성율이 각각 20%, 25%, 63.2% 증가하였고, 평균도 .20, .25, .63 증가하였다. T-검증에 의한 의미있는 결과는 역시 6학년 중에서 얻어졌다. 그러나 처치 후 논리 형성 학생으로의 전이는 없었으며, 과도기 학생의 비율만 35% 증가하였다. 위의 연구결과, 확률논리와 조합논리가 형성되지 않은 학생들은 학습을 통한 향상은 이루어 졌지만, 인지발달과 같은 질적인 변화는 이루어지지 않았다. 이 연구로 인하여 확률논리와 조합논리의 학습 효과가 큰 6학년 학생들의 인지수준 개선을 위한 여러 분야에서의 더 활발한 연구가 이루어지길 기대한다.

This study was carried out to investigate the occurrence situation and to provide the controlling practice of the Sycamore Lace Bug, Corythuca ciliata (Say) assaulting Plane roadside trees in Seoul area. The results are as follows: 1. The damage of leaves of host trees is mainly caused by nymphal Sycamore Lace Bugs which is large in number than adult ones and stipple and suck all day, and also their tar­like sticky excrements cover leaf stomas and erode leaf tissues. 2. The mean density of nymphs, adults, egg­mass per one damaged leaf were 7.7, 16.0, 7.6, respectively, and it appeared to be more high in northern Seoul area and the heart of the City, especially Jung­Gu and Jongro­Gu wards, and that situation seems to be aggravated by the recent warm and dry weather condition in Seoul area. 3. Adult Sycamore Lace Bugs are possible to move about with any transportation and overwinter in any place in that adults existed for 2 months in the air­tight vinyl pack, and thus, damages are expected to spread all over the nation. 4. in water spraying experiment, all the adult existed for a long time, while all the nymph was killed only in 2minutes, and, thus, powerful hydraulic sprayer can be obtained the desired results in decreasing the population of nymphs, but adults cannot be controlled except but the use of effective pesticides. The best timing of pesticide applications is early May when leaves of host trees newly develop and late July∼early August when summer rainy spell ends and new adult emergences, and for human health and effectiveness of the practice it is favorable to spray pesticide n night time. 5. The more weather condition become warm and dry, the more damages by the Bugs spread out, and, thus, in June and September, that precipitation would be less, it had to be irrigated and fertilized over the roadside trees. And at this time, Seoul City Hall and each ward office should establish collective and systematic plans for roadside tree maintenance as soon as possible.

In order to carry out TQM and 6 Sigma management, it is the key elements to make clear a goal and a mission. Above all, we can succeed in achieving a dramatic change and a great outcome only when we make clear the method, incentives, organization and plans under the clear objective. In order to secure the competitiveness against the external challenge, it is essential to keep the several crucial factors such as CEO's will, the systematic process to measure and manage, monitoring to satisfy customer's needs and an aggressive development of TQM activity to encourage the endeavour of the relentless enhancement, and also a positive effort is to be made for evaluating all quality culture like training experts internally by an outstanding training program under CEO's firm leadership. This study is carried out to understand that which features and factors of success can exist in a company culture if a company accepts a theoretical basis and concept, the general of TQM and 6 Sigma which are one of a management strategy, and carries out TQM and 6 Sigma for achieving improvement of quality and customer's satisfaction.
