Objective: The Lispro insulin has faster onset of effects and shorter duration than the human regular insulin, an analog of human insulin. The differences in the pharmacodynamics between the two types of insulin in the continuous subcutaneous insulin infusion(CSII) with insulin pump for treating the Korean Type 2 DM patients were analyzed. The effects on the regulation of blood sugar, the amount of insulin injected, and the frequency of hypoglycemia were compared between the lispro insulin and the regular human insulin. Method and Material: One hundred and three Korean Type 2 DM patients were randomly divided into two groups, 49 Lispro insulin and 54 Regular insulin.(Table 1) Both groups were treated for 14 days. Also at a set time before meal, insulin was injected as bolus, using a portable insulin pump, in both groups, 15 minutes before for lispro insulin and 30 minutes before for human insulin The HbA1C, C-peptide, AC/PC, height and weight were measured for each patients at the time of admission. The peripheral blood sugar level and insulin injection profile were recorded 7 times per day for each patients. Results: After treating for 7 days and 14 days, the blood sugar level normalized in both groups. There weren't any significant differences in blood sugar levels in both groups at point of the study, and also there weren't any differences in the frequency of hypoglycemia. In order to maintain the normalized blood sugar level, the lispro insulin group had higher total daily insulin requirement than the regular insulin group after 14 days of treatment (0.90±0.35 vs 0.73±0.39u/kg/day, p<0.05) This difference is probably due to the difference in basement insulin requirements rather than prandial insulin requirements (0.32±0.1 vs 0.43± 0.09u/kg/day, p<0.001). Discussion: In the hospitalized Korean Type 2 DM patients with CSII treatment, continuous subcutaneous insulin infusion therapy using lispro insulin has convenience in usage compared to the regular insulin. However, there were not any differences in the blood sugar levels. Also lispro insulin requires more insulin in order to maintain normal blood sugar level, which is probably due to the increase in the basal requirement. Also there were not any difference in the frequency of hypoglycemia.

지속적인 기립 작업에 의한 만성 하지 정맥 부전증 1예

정철,임현술,유선희 東國大學校醫學硏究所 2003 東國醫學 Vol.10 No.1

저자들은 10년 간 자동차 부품 조립공장에 근무하면서 지속적인 기립 작업에 의하여 하지 정맥류가 발생하였고 이후 하지 정맥 혈전증이 합병되어 통증과 부종을 수반하는 만성 하지 정맥 부전증으로 업무상 질병이 인정된 증례를 보고하는 바이다. 환례는 44세 여자로 1966년부터 우측 하지에 정맥류가 발생하였고 2001년 6월부터 시작된 하지 통증과 부종으로 2001년 7월 25일 정확한 진단을 위해 병원을 방문하였다. 과거력상 2001년 7월초 진단된 결핵 이외에는 혈관질환 등 기타질환을 앓거나 약물을 복용한 것이 없었고, 가족력과 사회력 조사에서도 정맥류와 관련된 특이한 점은 없었다. 환례는 현 직장에 1991년 입사하여 10년 간 동일한 조립공정 업무를 수행하였다. 작업은 계속 한 자세로 서서 일하는 형태였으며, 하루 총 작업식간은 8시간이었다. 진찰 소견상 우측 하지 후슬와부에 정맥류가 관찰되었고, 압박시 하지 통증과 부종이 관찰되었다. 입원시 실시한 우측 상행 하지정맥 조영술 검사상 호가장된 다수의 정맥이 장딴지에서 보이고 오금정맥이 하부 하지부에서는 불투명화 되지 않아 약 1개월간 병원에 입원하여 혈전증에 대한 항응고제 치료를 시행 받았다. 환례와 동일한 작업을 하는 동료근로자는 12명으로 작업 후 하지 통증은 모두 경험하였다고 하였으며, 이들 중 1례는 하지 정맥류가 관찰되었다. 프로트롬빈시간은 입원일 9.8초였다가 이후 정상으로 회복하여 퇴원시 11.5초를 보였으며, 활성 부분트롬보플라스틴시간도 입원 당시 퇴원시 33.4초로 회복되었다. 하지 통증 및 부종은 입원 중 점차 감소하였고 내원 당시 방사선 검사상 관찰되었던 하지 정맥 혈전도 소실되었다. 본 환례를 통하여 장시간 서서 일하는 근로자는 하지 정맥류에 대한 발생 가능성을 염두에 두고, 하지 통증이나 부종이 동반될 경우 혈전 여부 검사를 시행하여야 할 것이며, 그 원인추구에 있어서 반드시 직업관련성을 조사해 보아야 할 것이다. 작업장내 장시간 서서 하는 작업이 있을 경우에는 정기적인 검진을 통해 유소견자를 가려내고, 혈전증 예방을 위해 한 쪽 다리는 교대로 올려놓을 수 있는 발받침대를 설치하거나 작업 전 압력 스타킹을 신게 하는 등의 작업환경 개선에 대한 노력을 강조하여야 할 것이다. We report a case of chronic venous insufficiency with a history of 10 year standing work. The authors reviewed the clinical and hematologic features of the case. We also reviewed the job contents of her workplace. The worker was a 44-year old female who had worked in a mobile accessory factory for 10 years (1991-2001). She had been founded right leg varicous vein since 1996. The varicose veins induced severe pain and edema on June 2001. By venography, thrombus were detected and finally diagnosed as venous thrombosis on 25th July 2001. She regarded the occupational disease by longstanding work of standing position. She received anticoagulant treatment by one-month admission, and then improved the symptom and hematologic laboratory results. To prevent chronic venous insufficiency, we must modify working environments, begin comprehensive medical surveillance, educate workers on risk of lower leg venous problems, and increase workers awareness of safety regulations in the workplace.

鄭性煥,兪昌道,金善政 大田産業大學校 2000 한밭대학교 논문집 Vol.17 No.1

A study has been conducted experimentally on natural convection heat transfer characteristics of a heating flat plate with heat diffusion fins in air. The effects of heat diffusion fin lengths, heating plate temperature, air velocity, and Rayleigh numbers are mainly investigated. The mean heat transfer coefficient decreases as a dimensionless fin length increases and heating place temperature 60℃ is the best at constant heat flux. The mean Nusselt number increases with increasing Rayleigh number and Reynolds number and H/S = 1.0 in the dimensionless fin length is found to be the optimun size in a tested length, 1.0≤H/S≤4.0

鄭仙英,劉永山 대구효성가톨릭대학교 1994 연구논문집 Vol.49 No.1

대추의 結實安定윽 위한 墓礎 硏究로써 무등과 복조品種를 팡시하여 대추꽃의 형태적특성과 開花時期, 開花時刻,開花段階 및 柱頭의 receptivity등을 硏究 調査하여 다음의 結果를 얻었다. 대추꽃은 花器構造가 특이하여 꽃받침과 화반이 發達되고 꽃잎은 退化되어 있었다. 小花의 開化過程은 7段階로 子분되었으며 꽃받침이 수평으로 展開되는 4段階를 完全開花로 보았다. 대추꽃은 11∼12時부터 꽃봉오리가 열개되어 2시경에 開花最盛期를 보였으며 氣溫과 일조시수에따라 開花時刻이 多少 變化되었다. 開葯은 꽃잎에서 수술이 分離됨과 同時에 일어났으며 화사의 탄력과 訪花昆蟲에의해 受粉이 이루어졌다. 開葯時 花粉 發芽率은 60%이상이었으나 時間이 經過함에 따라 점차 감소되어 18시간이후에는 6%에 불과하였다. 柱頭上에 受粉된 花粉은 수분후 12시간 이후부터 發芽되기 시작하여 24시간까지 發芽率이 擔加되었고 柱頭上의 花粉發芽率은 開花當日이 가장 높았다. This experiment was conducted to investigate the floral morphological characteristics and their flowering habits such as flowering duration, opening time of day, flowering stage and stigma receptivity with 'Moodeung' and 'Bokjo' Chinese jujubes during blooming period. The results were as follows : Sepal and disc are specially developed but petal degenerated in florets of cyme inflorescence. Jujube trees showed very long blooming period and the flowering continued during about 55-60day until middle of August. Anthesis was completed between 12:00 and 4:00 PM in the used jujube cultivars and flowering stage was divided into seven stages. Flowering time of day was changed by atmospheric conditions such as temperature,sunshing hours. Anther dehiscence started on the time when the stamens emerged from petal and then pollens were rapidly transfered by pollinator. But unless disturbed pollen grains were sticky and remained on the anther. Percentage of pollen germination showed over 60% shortly after anther dehiscence, But it was gradually decreased and then was only 6% in 18 hours after anther dehiscence. Germination of pollen grains on stigma began from 12 hours after pollination and the receptivity of stigma showed high during 4 hours after anthesis.

김유정,정일선,최영주 신라대학교 자연과학연구소 2006 自然科學論文集 Vol.15 No.-

해양심층수의 첨가에 따른 항산화력과 된장에서 분리한 Bacillus, 석유분해균인 Sphingomonas 및 효모의 증식을 측정하였다. Bacillus와 Sphingomonas 경우는 KDMW와 다나수의 첨가에 의해서 균주의 생육이 증가되었을 뿐만 아니라 정지기 및 사멸기에 도달하는 시간도 연장되는 것으로 보아 심층수에 있는 미네랄이 이러한 생리활성을 나타내는 것으로 추정된다. 효모의 경우는 심층수의 첨가에 의하여 대조구와 별다른 차이를 보이지 않고 있다. 항산화력의 경은 KDMW를 50%까지 첨가 했을 경우는 25% 항산회력을 나타냈지만 60% 이상 첨가하면 오히려 항산회력이 현저히 감소하였다. 다나수의 경우는 40 - 100% 범위내에서 약 20%의 유사한 활성을 나타냈다. Korean deep mineral water (KDMW) has a similar mineral composition with deep sea water KDMW has demonstrated its usefulness and attracted in the medical fields. KDMW intake improves antioxidant activity and the growth of fermentation related strains. The antioxidant activity was increased up to 23% by the addition of 40% KDMW. The growth rate of Bacillus sp. on medium containing KDMW(40%) was faster than that of the strain on the medium without it. These results suggest that the minerals in KDMW play an important role for activation of immune system and the microbial growth. In addition to, it is considered that the study on the effects of abundant minerals of deep mineral water in the fermentation will by continued.

차정열,이기준,박선형,김태원,유형석 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.3

제논 플라즈마 아크 광중합기나 LED 광중합기가 치과영역에 소개된 이후로 기존의 텅스텐 할로겐 광중합기를 사용할 때에 비해 교정장치의 부착시간이 현저하게 줄어들 수 있게 되었다. 제논 플라즈마 아크 광중합기에 대한 중합시간과 전단강도에 대해서는 여러 연구가 있어왔던 반면, LED 광중합기를 이용하여 교정용장치의 부착을 위한 중합시간에 대한 연구는 미진하다. 본 연구의 목적은 LED 광중합기의 중합시간에 따른 결합강도를 플라즈마 아크 광중합기와 비교하여 적절한 브라켓의 부착강도를 얻기 위해 요구되는 중합시간을 알아보는데 있다. 120개의 발치된 사람의 소구치에 컴포짓 레진으로 브라켓을 부착시킨 후 4초, 6초, 8초 동안 플라즈마 아크 광원과 LED 광원으로 각각 중합시켰다. 그 후 결합강도를 만능시험기(Universal Testing Machine)로 계측한 결과, 플라즈마 아크 광중합기에서는 4초 이상에서, LED 광중합기에서는 8초 이상의 중합시간에서 기존의 할로겐 광원을 40초간 노출시켰을 때와 비슷한 전단결합강도를 나타내었다. 플라즈마 아크 광중합기와 LED 광중합기의 중합시간이 접착제 잔류지수(adhesive remnant index) 수치에 대해 영향을 미치지 않았다. With the introduction of the xenon plasma arc curing light and the LED curing light as orthodontic curing lights, the polymerizing time of orthodontic composites has clearly decreased. In contrast to various research cases regarding the polymerization time and bond strength of the xenon plasma arc curing light, not enough research exists on the LED curing light, including the appropriate polymerization time. The objective of this research was to compare the bond strength of the plasma curing light and the LED curing light in regards to the polymerization time. The polymerization time needed to achieve an appropriate adhesion strength of the bracket has also been studied. After applying orthodontic brackets using composite resin onto 120 human premolars, the plasma arc curing light and the LED curing light were used for polymerization for 4, 6, and 8 seconds accordingly. This research proved that the LED curing light provided appropriate bond strength for mounting orthodontic brackets even with short seconds of polymerization. The expensive cost and large size of the device limits the use of the plasma arc curing light, whereas the low cost and easy handling of the LED curing light may lead to greater use in orthodontics.

Objectives : To report cubital tunnel syndrome due to repetitive motions. Methods : A worker complaining muscle weakness and atrophy of the right hand intrinsic muscles admitted to a hospital. We evaluated him with blood tests, neurophysio-logic studies (NCV & EMG), plain X-ray and US at the both elbows. We investigated his occupational history, and videotaped his work motions based on the work cycle at his previous work site. Finally, an ergonomics expert analyzed the motions using rapid upper limb assessment (RULA). Results : NCV & EMG studies reveals slow conduction velocity on both ulnar nerve across the elbow, more severely in the right side. US shows us compatible finding with diffuse neuritis of both ulnar nerves at both elbows. RULA score is 7. Conclusion : We confirmed that the worker's symptoms were related to his previous jobs demanding repetitive motions using the elbow joints. It is necessary that we should prepare appropriate measures to evaluate, prevent, rehabilitate, and help injured workers to return to work.
