전광 통신의 시대를 맞이하면서 광섬유의 수요가 급증하고 있어 보다 질 좋고 생산 단가가 절 감된 광섬유의 제조가 중요하며 이것은 기존 기술의 최적화와 새로운 제조기술의 개발에 의하 여만 가능할 것이다. 생산성 및 광섬유의 질이 화학증착을 비롯한 각 공정에 의지하므로 각 공 정의 최적화가 중요하며 광섬유 제조 화학증착과정에서 층착 성능은 thermophoresis로써 결정지 어지는 입자운동 및 부착에 의지하므로 향상된 증착 성능을 얻기 위하여서는 각과정에서의 열 전달, 유체유동 및 입자 부착 해석이 선행되어야 한다. 증착의 균일성, 증착효율 및 증착률의 향상을 위한 노력은 모델링을 포함한 실험적 연구 및 새로운 기술의 개발 및 시도가 필요하다고 할 수 있다.

Growth hormone deficiency is the medical condition of inadequate production of growth hormone. Growth hormone deficiency in adults is not common, but it may feature a diminished, lean body mass, poor bone density and a number of physical and psychological symptoms, including poor memory, social withdrawal and even depression. Abnormally low growth hormone levels in adults typically result in a diminished quality of life and it can even be disabling. The physical symptoms include loss of strength, stamina, and musculature. Growth hormone deficiency can also impair the biological and physiological/functional substrate of penile erection, which can be, at least in part, restored by the normalization of the plasma levels of growth hormone. This is a report on a 63-year-old man who suffered with severe erectile dysfunction and loss of libido due to growth hormone deficiency. Upon growth hormone administration, his erectile function improved dramatically.

As part of planning for waste minimization, decontamination foam has been considered as a potential application for the cleaning of radioactive contaminant. In this study, we synthesized silica particles to improve foam stability by varying synthesis parameters. Cetyltrimethylammonium bromide (CTAB) was found to influence the stability of the decontamination foam. The reason was that higher interaction between $SiO_2$ nanoparticles and surfactant at the air-water interface in aqueous solution is beneficial for foam stability. CTAB can also be used as an additive for the aggregation of silica nanoparticles. In the separation of $SiO_2$ nanoparticles, CTAB plays a critical role in the nanoparticles flocculation because of the charge neutralization and hydrophobic effects of its hydrocarbon tails.
