나일론 직물들이 전류세기 5, 10, 15, 20 A, 공급속도 5, 10, 15 m/min로 코로나 처리되었다. 나일론 직물의 표면변화를 X-ray 회절장치, 주사전자현미경(SEM)과 X-ray 광전자분석기(ESCALAB)로 확인하였다. 또한 물리적 성질의 변화를 인장 인열강도, 접착 및 습윤강도를 통하여 측정하였다. 접착에 사용된 접착제는 열경화성 반응형 폴리우레탄 핫 멜트 접착제이다. 대기압에서 코로나 방전처리에 의해 나일론 직물에 관능기들이 도입되어졌고, 그 결과 접착력은 향상되었다. 코로나 처리된 나일론 직물의 접착강도는 전류 세기가 증가할수록, 공급속도가 감소할수록 증가하였다.

In this paper we investigated the characteristics of surface degradation in silicone rubber due to corona exposure and recovery mechanism. It was shown that surface free energy was 22.42 mJ/$m^2$ on initial sample but surface free energy was approximately increased to 71.14 mJ/$m^2$ after 45 minutes. However, surface free energy on silicone rubber after corona discharge treatment was completely recovered within a short time due to diffusion of low molecular weight(LMW) silicone fluid. It was shown that corona discharge insured the increase of diffusible LMW chains, which could lead to recover the surface hydrophobicity. 200～370 g/mol distribution of LMW silicone fluid which was extracted by solvent-extraction with gel permeation chromatography (GPC) was contributed to recovery. The surface degradation characteristics on silicone rubbers and the recovery mechanism based on our results were discussed.

In this paper we investigated the changes of surface hydrophobic characteristics on silicone rubbers by corona discharge treatment and also investigated the distribution and the behavior of low molecular weight(LMW) silicone fluid which was extracted by solvent-extraction with gel permeation chromatography(GPC). It was shown that contact angle was $110.5^{\circ}$ on initial sample but contact angle was approximately decreased to $10^{\circ}$ after 45 minutes. However the surface hydrophobic characteristic on silicone rubbers which were removed from corona discharge was recovered within 5 hours. It was shown that corona discharge insured the increase of diffusible LMW chains, which could lead to recover the surface hydrophobicity. The surface hydrophobic characteristics on silicone rubbers and the recovery mechanism based on our results were discussed.

본 연구에서는 고경질 도막재로 PET 필름을 접합하는 시공방법에 있어서 PET 필름의 표면처리 조건 및 겹침이음 길이에 따른 접합특성 및 내구특성을 검토하였는데, 그 결과 무처리 보다 코로나 방전 처리에 의해 접촉각, 접합 인장강도, 벗김저항성이 개선되었다. 특히 시험체 E (코로나 방전+프라이머+강접접착제+폴리에스터 부직포)에서 가장 높은 것으로 나타났으며, 특히 겹침 이음길이 15mm 이상일 때 16주간 장기간 열화처리에도 안정적인 접합성능을 확보하는 것으로 나타나 방수재료로서 수밀성을 확보할 것으로 판단된다.

Textile wet-processing industry usually five rise to environmental pollution problems caused by using chemical substance. The objective of this study is to apply enzymes for wool and reduce the environmental problems. Three commercial protein degradation enzymes and a cellulose degradation enzyme as a reference were treated to prevent the shrinkage of wool fabric on laundering. Shrink resistant effects used change with the kinds of enzyme, the amount of enzyme, assistant chemicals, and the pre-treatment condition of wool fabric. When pre-treated with corona before enzyme treatment under ultrasonic condition, the weight loss was increased and strength was decreased and elongation was increased. Both corona pre-treatment and the addition of $Na_2SO_4$ also decreased shrinkage of wool fabrics on laundering. The existence of assistant chemicals increased alkali solubility of wool fabrics.

COVID-19 (Corona Virus Disease-2019) is an infectious respiratory disease caused by the most recently discovered coronavirus, SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona virus-2). This new viral disease was unknown before the outbreak began in Wuhan, China, in December 2019. As of November 16th 2020, it affects about 54.3 million populations, death troll increased to 1.32 million cases in worldwide. Whereas in India 8.85 cases are infected with COVID-19, of which 1, 30, 112 cases were died. Till now there has been no specific anti-virus drug or vaccines are available for the treatment of this disease, the supportive care and non-specific treatment to the symptoms of the patient are the only options in Biomedicine, the entire world turns its attention towards alternative medicine or Traditional medicine. Siddha medicine is one of the primordial systems of medicine practiced in the southern part of India, it dealt a lot about pandemic, and its management. This review provides an insight into Pandemic in Siddha system and its management in both ancient history and modern history, National and state level Government policies related to current pandemic, World Health Organization (WHO) guidelines on usage of unproven drug during infectious disease outbreak, Preparedness of Siddha system during a pandemic outbreak Challenges and Recommendations.
