Objective : This study was carried out to investigate the effects of DDT on the brain damage and hypertension. Methods : We observed the effect of Dodamtang(DDT) extract on KCN-induced coma, focal brain ischemia by MCA occlusion, cytotoxicity and protection of PC12 cells and B103 cells induced by amyloid ${\beta}$ protein(25-35). To prove the effect of DDT as a blood pressure depressant, we measured aldosterone, renin activity, catecholamine, sodium and NO density using the seperated blood plasma. Results : DDT showed a protective effect on cytotoxicity of PC12 cells and B103 cells induced by amyloid ${\beta}$ protein(25-35) in a dose dependent manner and proved the significant abridgement of brain ischemic area and edema induced by MCA occlusion, a critical decrease of neurologic deficitic grade in the fore-limbs. DDT didn't reduce the duration of KCN(1.87mg/kg iv.)-induced coma and prolonged the survival rate in the case of KCN(3.0mg/kg iv.)-induced coma by the ratio of 20%. While DDT increased the value of NO in SHR, it significantly decreased the blood pressure of SHR and the value of aldosterone& epinephrine in SHR. Conclusions : These results suggested that DDT might be usefully applied for treatment of hypertension, cerebral infarction, and brain damage.

Objectives: The purpose of this study is to report the effect of Gamsaengwha -tang with Deer antler on three postpartum women with anemia. Methods: The three postpartum women with severe anemia among postpartum women who admitted our hospital were treated by oriental treatments such as herbal medicine(Gamisaengwha-tang with Deer antler). Results: After treatment, the measurements of hemoglobin was increased and Anemia was improved. Conclusion: After delivery, many postpartum women have tendency to become anemic. Saengwha-tang and Deer antler became known to be good for anemia in oriental medicine. So the three postpartum women with severe anemia among postpartum women who admitted our hospital were treated by Gamisaengwha-tang with Deer antler. After treatment, the measurements of hemoglobin were increased comparative quickly, and anemia was improved. This case report shows that the Gamisaengwha-tang with Deer antler is effect for treatng anemia. Anemia will improve not only treating by Saengwha-tang except Deer antler but also treating by iron supplement, so we need more comparative study and observation and need more practical use of herbal medicine with Deer antler for anemia and disease of postpartum women.

Objective: The purpose of this study is to report the case of a patient with non-small cell lung adenocarcinoma (NSCLC) with anaplastic lymphoma kinase (ALK) mutation treated by Samchilchoongcho-Jung in conjunction with Crizotinib. Methods: An NSCLC patient diagnosed with multiple pleural and lymph nodes metastasis has been taking Crizotinib (500 mg/day) since January 2014. The patient has been treated with Samchilchoongcho-Jung (1,500 mg/day) since June 2014. The tumor size was measured by computed tomography (CT) and laboratory analysis was conducted. Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. Results: After combining treatment, stable disease was shown on CT. The tumor marker (CEA, Cyfra 21-1) levels were maintained. NCI-CTCAE 5.0 showed no adverse events. Conclusion: This case study suggests that Samchilchoongcho-Jung may contribute to tumor response, in conjunction with Crizotinib on the treatment of patients with NSCLC.

We introduced simple fabrication process for field emission devices based on carbon nanotubes (CNTs) emitters. Instead of using the ITO material as a transparent electrode, a metal (Au) with thickness of 5-20nm was used. Moreover, the ITO patterning process was eliminated by depositing metal layer, before the CNT printing process. In addition, the thin metal layer on photo resist (PR) layer was used as UV block. We fabricated the CNT field emission arrays of triode structure with simple process. And I-V characteristics of field emission arrays were measured. The maximum current density of $254{\mu}A/cm2$ was achieved when the gate and the anode voltage was kept 150V and 3000V, respectively. The distance between anode and cathode was kept constant.

The postal or group questionnaire survey was conducted to inquire into the cause of collision between fishing vessel and non-fishing vessel targeting fishing vessel personnel(FVP), non-NFVP and a person involved in a marine accident. As a result, we could verify the root cause of collision, a negligence of lookout which noted overwork for FVP and careless for non-FVP. The cause of collision by inappropriate avoid action was poor communications for FVP and non-FVP. To reduce collision, we need to be trained to take a sharp lookout, a radio communication by VHF and the collision avoidance actions by early and substantial action to keep well clear. The results are expected to contribute for the reduction of collision and victims.

우리나라는 세계 TV 시장의 선두에서 산업을 주도하고 있으나 최근 중국의 거대 내수시장 및 기술 개발 등의 기반에 따른 추격의 위협을 받고 있다. 스마트미디어 산업으로의 패러다임 전환과 스마트 TV의 등장으로 이러한 중국의 추격에 대응할 수 있는 경쟁우위 전략을 모색해 본 결과 소비자 주도형 콘텐츠 혁신이 새로운 기술적 관점의 기회의 창으로써 제시되었으며 이는 향후 우리나라 소프트웨어 산업의 발전에 긍정적 영향을 끼칠 것으로 판단된다.

We have examined alcohol-induced malformation of chick embryo. Alcohol was considered to induce the malformation of developing embryo and to have bad effects on embryonic stage. We injected alcohol into air sac on day 4 of incubation. Ten ％ alcohol-treated group showed a little decrease on their body length compared to the untreated group and distilled water-treated group. Thirty ％ alcohol-treated group showed significant decrease on their body length compared to the untreated group and 10％ ethanol treated group. In addition, we have observed malformation of eyeballs and bills. These results indicate that alcohol affects chicken developments and brings on malformation of developing stage.

Visco-elastic damping material for reducing heavy-weight floor impact noise and vibration in reinforced concrete structures was tested according to its thickness in the damping layer. The effect of damping material was compared with 20, 15, 10 and 5mm thickness. The wave propagation characteristics was measured for suggestion of an efficient method to reduce the floor impact noise. The method was proposed using the flexural wave propagation characteristics. The result showed that reduction of the thickness of damping layer made a slight difference; the natural frequency moved to higher frequency and the amplitude increased at low frequencies with 5mm thickness of damping material.
