본 연구의 목적은 공기청정기의 극세필터(프로필터), 집진필터, 헤파(HAPA-High Efficiency Particulate Air)필터, 탈취필터 등을 사용하는 일반적인 필터의 구조를 분석하고 초미세먼지, 유해가스 및 살균 정화성능을 향상시킬 수 있는 새로운 형태의 공기정화 필터 디자인을 제시하는 것이다. 기존 단계적 여과 필터 형태에 광촉매 필터 시스템을 추가하는 방법으로 연구하였으며, 광촉매 필터는 좌우측의 UV-LED 설치 프레임과 광촉매 코팅 허니컴(honeycomb)프레임 3단 결합구조의 디자인으로 제안했다. 광촉매 필터의 살균소독 효과에 대해서는 향후 연구가 필요하며, 본 연구에서는 공기청정기에 광촉매 필터 적용 및 구조에 대하여 보고하고자 한다. The purpose of this study was to analyze the structure of general filter using ultrafine filter (Profilter), dust collector filter, HEPA (HAPA-High Efficiency Particulate Air) filter, deodorized filters, etc. of air purifiers and to study new types of purified filters that can improve ultrafine dust, harmful gases, and sterilization cleanup performance. The study was also conducted by adding photocatalyst filters to the existing step-by-step filtration filter types, which were proposed in the design three coupling structure filters of the left and right UV-LED installation frames and the photocatalyst coating honeycomb frame. Future research is needed on the effect of photocatalyst filters. This study was to investigate the application and structure of photocatalyst filters to air purifiers.

A single specimen of Microphis brachyurus brachyurus, belonging to the family Syngnathidae, was collected for the first time in Korea (Busan) on July 10, 2013. This specimen had 35 dorsal fin rays, 20 pectoral fin rays and 9 caudal fin rays. M. brachyurusbrachyurus differs from Syngnathus schlegeli, the most common pipefish in Korean waters, in its body proportions (longer trunk than tail in M. brachyurus brachyurus vs shorter trunk than tail in S. schlegeli), configuration of the lateral ridge (confluent with the inferior tail ridge vs confluent with the lateral tail ridge, respectively) and the number of caudal fin rays (9 vs 10, respectively). We suggest the new Korean names “Zzal-beun-ggo-ri-sil-go-gi-sok” for the genus Microphis and “Zzal-beun-ggo-ri-sil-go-gi” for the species M. brachyurus brachyurus.

The changes in atomic bonding state at the interface of ultra thin Ni film (25 Å) with SiC were investigated as a function of annealing temperature using synchrotron radiation photoemission spectroscopy (SRPES). From these, the early stage in the reaction to form Ni silicide was examined. It was found that Ni_2Si began to form below 600℃. However, at 300℃ Ni atoms migrated on the surface of SiC, leading to the formation of Ni islands and the substrate is partially exposed, prior to the formation of Ni silicide. When Ni_2Si was formed, the binding energy of SiC bond was not changed, but work function of the contact layer was increased. This provides the evidence that Schottky barrier height was increased with the formation of Ni silicide via the increase in work function of contact layer.

Purpose: We investigated chief complaints and ocular disorders in infants under one year of age and analyzedthe association between complaints and disorders. Methods: The medical records of 815 infants were reviewed. Chief complaints were grouped into the following11 categories: eyelid drooping, epiphora (tearing), ocular discharge, lid swelling, eyelashes touching the eyeball,abnormalities of the anterior segment, abnormal eyeball movement (e.g., squint or nystagmus), red eye,trauma, poor eye contact, and miscellaneous. We performed ophthalmologic examinations at the doctors’ discretionand analyzed the relationship between chief complaint and final diagnosis. Results: Mean age of visiting the outpatient clinic was 6.09 ± 3.07 months. The most common complaint wasocular discharge, followed by abnormal eyeball movement, epiphora, and eye redness. Among infants with oculardischarge, most were attributed to congenital nasolacrimal duct obstruction (155 infants) and conjunctivitis(75 infants). A total of 160 guardians complained of abnormal eyeball movement and 86 of 160 infants (51.9%)suffered from pseudoesotropia. Additionally, exodeviation and esodeviation was found in 17.9% and 16.4%of infants, respectively. Eight guardian complained of poor eye contact in their infants and these infants werediagnosed with retinal disorders (3), congenital optic nerve disorders (2), cataract (1), glaucoma (1), and highhyperopia (1). Conclusions: The most common ocular symptoms in infants under one year of age included ocular discharge,epiphora, and eye redness. However, infants with poor eye contact or suspected abnormal eye movementshould undergo a full ophthalmologic examination.

The continuous welded rail (CWR) track reduces maintenance costs and increases passenger comfort etc. Although the CWR track has many advantages mentioned, the stability of the track is highly affected by change of temperature. Where the CWR track is over the bridge, the longitudinal force and displacement are occurred by the track-bridge interaction. To guarantee the stability of the CWR track, therefore, the analysis of track-bridge interaction should be performed. The UIC(2001) dose not suggests the method and the regulations of the curved track-curved bridge interaction but those of the straight track-bridge interaction. In this paper, the analysis technique of the curved track-curved bridge interaction is presented. The numerical analysis of the interaction between curved track and 2-span curved continuous bridge is performed. 장대레일 궤도는 열차의 승차감 향상과 유지보수의 비용절감 등 많은 장점을 가지고 있지만, 온도하중에 의하여 좌굴이 발생할 수 있는 단점이 있다. 또한, 교량구간에서는 온도하중과 열차하중으로 인하여 장대레일에는 추가적인 축력 및 변위가 발생하므로 궤도와 교량의 상호작용을 고려한 해석을 통하여 장대레일 궤도의 안전성을 검토해야 된다. UIC(2001)에서는 직선 궤도와 직선 교량의 상호작용해석방법과 기준을 제시하고 있지만, 곡선 궤도와 곡선 교량의 상호작용해석방법이나 기준은 제시하고있지 못하고 있다. 따라서 본 논문에서는 곡선 궤도와 곡선 교량의 상호작용해석을 수행하기 위한 해석모델을 제시하고, 2경간연속 철도교에 대하여 곡선 궤도와 곡선 교량의 상호작용해석을 수행하였다.
