우리나라는 선박관리산업의 중요성을 인식한 해운업계 및 학술단체의 전문가들에 의해 지속적으로 노력한 결과 최근 국회의원의 발의에 의하여 "선박관리산업발전법안"이 제안되었다. 이러한 성과는 우리나라의 선박관리산업이 선진국 대열에 진입하게 되는 결정적인 계기가 된다고 생각한다. 이 연구는 최근 발의된 우리나라 "선박관리산업발전법안"을 각 조문별로 소개하고, 조문별 분석을 통해 법적인 문제점과 실효성을 검토하여 개선방안을 제시함으로써 향후 우리나라 선박관리산업의 발전을 위한 법과 제도의 발전에 기여하는 것을 궁극적인 목적으로 한다. 이를 위해 우리나라 "선박관리산업발전법안"의 구성, 목적, 용어의 정의, 다른 법률과의 관계 등을 중심으로 개념을 소개하고, 이 법률안의 핵심이라고 할 수 있는 선박관리산업의 육성 및 지원, 그리고 선박관리우수사업자의 인증을 중심으로 구체적 실효성을 분석하였다.
Glutamate-induced oxidative injury contributes to neuronal degeneration in many central nervous system (CNS) diseases, such as Parkinson’s disease, Alzheimer’s disease, epilepsy and ischemia. Inducible heme oxygenase (HO)-1 acts against oxidants that are thought to play a role in the pathogenesis of these diseases. The EtOH extracts of Viola mandshurica (NNMBS274), Viola patrinii (NNMBS275) and Viola papilionacea Pursh (NNMBS276), origin plants of Violae Herba, showed the potent neuroprotective effects on glutamate-induced neurotoxicity. Among them, NNMBS275, the extract of V. patrinii possessed the protective effects against glutamate toxicity by inducing the expression of heme oxygenase (HO)-1 in the mouse hippocampal HT22 cells. These results suggest that extracts of V. patrinii could be the effective candidates for the treatment of ROS-related neurological diseases. Furthermore, it is suggested that the protective effects of V. patrinii extract due to inducing the expression of HO-1 as an antioxidant/cytoprotective target
프리캐스트 콘크리트 골조에서 실물크기의 보-기둥 접합부 실험체 5개를 대상으로 반복가력 실험을 수행하였다. 지진하중을 받는 골조를 대상으로 1개의 일체식 실험체와 4개의 프리캐스트 실험체를 포함하여 5개의 1/2스케일의 내부 보-기둥 접합부를 대상으로 하였다.주요 변수는 보의 구조적 연속성을 확보하기 위한 접합부의 형태와 접합부의 특별한 보강형태(섬유콘크리트와 횡보강근)로 하였다. 실험체는 강기둥-약보 개념에 따라 설계하였다. 보 철근은 접합부에 큰 비탄성 전단력이 작용할 경우 보에 소성힌지가 발생하도록 계획하였다. 접합부의 성능평가는 접합부의 강도, 강성, 에너지 소산능력과 층간변위비로 평가하였다. 실험결과 실험체의 파괴는 보의 소성힌지부에서 파괴되었다. 보-기둥 접합부의 성능은 대체적으로 우수한 것으로 나타났다. 접합부의 강도는 일체식 RC 구조의 비해 1.15배 정도 향상되었다. 층간변위 3.5%때의 강도에서 실험체는 ECC의 인장변형능력과 철골연결재의 항복에 의해 연성거동 하였다.
This study was conducted to investigate optimal conditions for formation of synnemata from Beauveria bassiana. The strain of B. bassiana was isolated from a host of Oncotympana fuscata in Halla mountain of Jeju island. The yield of synnemata was the highest at application of brown rice (90%) and silkworm pupae (10%) media. On the other hand, the other media did not result in formation of synnemata. The highest formation of synnemata was achieved at conditions of moderate air inflow and 20℃. The optimal moisture and light intensity for formation of synnemata were 60% and 300 lux, respectively. In addition, inoculation of the liquid spawn resulted in higher yield than that of asexual spore.
The effects of La addition to Ni/CeO2 methane partial oxidation catalysts were investigated. Catalysts were prepared by the impregnation and urea methods. In the preparation of catalysts, La content was changed from 1 wt% to 3wt%. Catalysts that contain 2wt% La showed the highest methane conversion of about 80% and CO selectivity of 84% and H2 selectivity of 70%. This result may be stemmed from that, when La content is 2wt%, a fluorite oxide-type structure is well formed and carbon deposition is also decreased. Among the catalysts, 2.5wt% Ni/Ce(La)Ox showed the highest catalytic activity. From the experiment of changing reaction temperature with 2.5wt% Ni/Ce(La)Ox catalyst, it was found that the optimum reaction temperature is 750℃ and at this temperature methane conversion was about 90%, CO and H2 selectivities were 94 and 80%, respectively.
본 연구는 경남 진주에서 여름철에 풀숲에서 아름다 운 소리를 들려주는 정서곤충의 한 종류인 여치 (Gampsocleis sedakovi abscura Walker)에 관한 생 활사를 3년간 (2005~2007)에 조사한 결과이다. 여치는 1년에 1세대 발생하며, 성충의 몸길이는 암컷이 60 ㎜ 정도이며 수컷은 50 ㎜정도이었다. 몸의 색깔은 녹색 또는 암갈색의 두 종류가 있었다. 땅 속에서 알 상태로 월동하며, 야외에서 3월 상순부터 약충을 볼 수 있었으 며 성충의 우화 최성기는 7월 상순이었다. 야외에서 알 기간이 269일, 약충기간이 88일로 성충이 되기까지 357 일이 걸렸다. 3년간 평균 산란기간은 63일이었고, 산란 수는 평균 94개였다. 평균수명은 암컷이 90일, 수컷이 82일이었으며, 성비는 암컷이 52%이었다. 일일 중 성충 의 우화는 오전 8시에서 10시 사이가 가장 많았다.
The objection of this research is to conform of practicable possibility and recycling of producing junk after citrus fruits is processed. In the middle of practicable possibility, with verification of antibiosis that tactiling sensibility in a microorganism. With extracting d-limonene oil that have 70~90% a component of oil out of junk citrus peel, making certain the about 12000ppm(1.2%) concentration of it. By means of antibiosis property over the a pathogenic bacterium as well as a residence bacterium, considerating the limit of application against daily living supplies needs to antibiosis. Antibiosis effect of a stationing bacterium in the body permanently and by means of antibiosis verification of special bacteria Propionibacterium Acnes that causative skin trouble is selected, in based the antibiotic sencitivity test check up result of minimal inhibitory concentration(MIC).
This study was conducted to investigate the effects of Takju lees hot water extracts on the blood pressure in spontaneously hypertension rats (SHR). Twenty eight male SHR were grouped by their blood pressure and fed a control diet or experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extracts for 4 weeks. Food intake was not significantly different among the groups. However, body weight gain was significantly lower in groups fed the Takju lees extract than the control group. The systolic blood pressure was significantly lower in the Takju lees extract containing groups (especially in G4 group) than the control groups. In addition, mean blood pressure {(systolic+dyastolic)/2} decreased with an increase in the amount of Takju lees extract in the diet and feeding period. Takju lees extract decreased angiotensin I converting enzyme (ACE) activity in a dose-dependent manner. These results suggest that the Takju lees extract exert an antihypertensive effect by decreasing ACE activity.
Today, wastes of much quantity by fast industrialization and increase in population, population concentration etc. of modem society are increasing. Much oyster shell is breeding by character and conduct of oyster-industry for a long time among them. Oyster shell which breed by-product in oyster cultivating industry that specific gravity of domestic seashore cultivating industry is high is causing environmental problem by problem and so on hindrance, nature spectacle's waste and health hygiene on administration if it is pollution of district along the coast fishing ground, number of public ownership being stored in open area in seashore. About new material just-in-time through recycling and he of oyster shell by these problem wide that study. Go forward more and investigate special quality that is oyster shell's physical chemistry red in this research and oyster shell oyster shell which cause several environmental problems developing ability agricultural chemicals that use this encapsulating micro by ability carrier that is environmentally application possibility examine wish to.
