삼국유사(三國遺事) 기이 권제일(紀異卷第一)에 보면 연오랑(延烏郞)과 세오녀(細烏女)에 대한 설화가 실려 있다. 우리나라에서 문헌으로는 유일한 일월신화(日月神話)로 알려진 연오랑과 세오녀에 대한 이야기는 그 구성이 특이하고 전개되는 이야기가 시사하는 바가 크다고 할 것이다. 이 이야기가 문헌상 유일한 일월신화라는 데는 모두가 인정하지만 설화의 내용에 대해서는 각기 다른 견해를 보이고 있다. 그러니 어찌하여 연오랑과 세오녀가 일본으로 갔는지에 대해서는 신라인의 일본 이주설이라던가 일본 신화와 연관성 등을 언급하는가 하면 일월신화 자체로만 보는 것 같아 만족할만한 결론에 이를 수 없기에, 연오랑과 세오녀가 일본으로 간 까닭에 대해 다른 각도에서 연구하여 이 설화가 말하고자 하는 숨은 뜻을 밝혀 보고자 하였다. 이 글에서는 연오랑과 세오녀를 실존 인물로 보지 않고 ‘해의 나라’의 상징으로 보고 연오랑과 세오녀가 일본으로 간 것은 해의 나라를 뜻하는 부상국(技奏國)의 이동으로 보는 것이다. 연오랑과 세오녀가 일본으로 가기 전까지는 우리나라가 부상국이었고 해의 나라였지만, 일월신(日月神)의 화신이라 할 그들이 일본으로 갔다는 것은 부상국의 지위가 더 동쪽으로 이동한 것으로 보는 것이다. 이러한 일련의 일들은 결론적으로 말해, 연오랑과 세오녀가 일본으로 간 것은 ‘해의 나라’의 지위가 일본으로 넘어간 것을 말하고 세오녀의 비단은 해를 상징하는 물건이기에 그것으로 하늘에 제사지내므로 해서 실제적 ‘해의 나라는 일본으로 갔지만, 신라도 해가 밝게 뜨는 ‘아침의 나라’로 거듭나는 상징적 의식이었다고 보는 것이다.

In-situ 도핑량이 다공성 3C-SiC 박막의 특성에 미치는 영향

This paper describes the elecrtical and optical characteristics of $N_2$ doped porous 3C-SiC films. Polycrystalline 3C-SiC thin films are anodized by $HF+C_2H_5OH$ solution with UV-LED exposure. The growth of in-situ doped 3C-SiC thin films on p-type Si (100) wafers is carried out by using APCVD (atmospheric pressure chemical vapor deposition) with a single-precursor of HMDS (hexamethyildisilane: $Si_2(CH_3)_6)$. 0 ~ 40 sccm $N_2$ was used for doping. After the growth of doped 3C-SiC, porous 3C-SiC is formed by anodization with $7.1\;mA/cm^2$ current density for anodization time of 60 sec. The average pore diameter is about 30 nm, and etched area is increased with $N_2$ doping rate. These results are attributed to the decrease of crystallinity by $N_2$ doping. Mobility is dramatically decreased in porous 3C-SiC. The band gaps of polycrystalline 3C-SiC films and doped porous 3C-SiC are 2.5 eV and 2.7 eV, respectively.

폐비닐로 개질된 아스팔트의 저장안정성에 관한 연구

아스팔트 개질재로 쓰이고 있는 폴리에틸렌은 아스팔트와의 비중차와 비상용성으로 인하여 상분리가 일어난다고 알려지고 있다. 본 연구에서는 상분리를 억제하기 위하여 폴리에틸렌을 가교시킬 수 있는 것으로 알려지고 있는 과산화물을 사용하여 상분리 억제를 시도하였다. 폴리에틸렌 수지로는 폐비닐을 사용하였으며, 과산화물로는 디큐밀퍼옥사이드와 로로일퍼옥사이드를 사용하였다. 현미경상으로는 과산화물이 첨가되어 상분리가 억제되었다. 그러나 유변물성을 측정한 결과는 아스팔트와 폴리에틸렌은(비록 폴리에틸렌이 가교된다 하더라도) 분자단위에서는 서로 섞일 수 없음을 보여주고 있다. 기계적 시험(인장강도, 마샬안정도, 동적안정도)에서는 매우 우수한 물성을 보여주어 소성변형에 대한 저항성이 크게 향상된 것으로 나타났고, 이는 기존의 슈퍼팔트보다 우수한 것으로 나타났다. It is said that polymer modified asphalt using polyethylene as modifier would show phase separation due to density difference and incompatibility between asphalt and polyethylene. In this study, to prevent coalescence of polyethylene in asphalt, we employed peroxides as phase separation inhibitor. On microscope, peroxides (dicumyl peroxide, lauroyl peroxide) with waste vinyl (comprising low density polyethylene) did not show phase separation, however, rheometer test showed phase separation at molecular level, i.e., polyethylene and asphalt are immiscible ultimately. Mechanical properties (tensile strength, Marshall stability, dynamic stability) showed waste vinyl-modified asphalts are highly resistant to plastic deformation and these properties are even better than those of Superphalt.

Marjolin`s ulcer is a rare and often-aggressive cutaneous malignancy that arises in previously traumatized or chronically inflamed skin, particularly after burns. We experienced two cases after burns. Case I involved a forty eight year-old man who had suffered from a flame burn at the parietal scalp area, where had been initially described three years earlier as a full-thickness wound including the pericranium. The man consulted us for a persistent ulcerative and infected wound on the burned lesion during the last 24 months, which turned out on the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) to be the squamous cell carcinoma with involving the skull and the dura mater. Although the posterior auricular lymph node was enlarged on the ipsilateral side, recent positron emission tomography (PET) CT did not show any metastatic lesion. It was impossible for us to resect the intracranial involvement of the tumor radically, and the postoperative PET CT still showed a focal fluorodeoxyglucose (FDG) uptake around the wall of the superior sagittal sinus. We think that an aggressive combined approach is essential for treatment in early stages for a high success rate, before the intracranial structures are involved because there is no consensus on the treatment for advanced disease, and the results are generally poor. Case 1 also did not involve a radical resection because of the intracranial invasion to the wall of superior sagittal sinus and the possibility of damage to the major cortical veins. He received adjuvant radiotherapy and must be followed periodically. Case 2 involved an eighty six year-old women who suffered from a painful scalp ulcer lesion after flame burns three years earlier. Unlike case 1, neither tumor infiltration into the dura nor lymph node enlargement was observed on the contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) CT. We did a radical resection of the tumor, including the involved bone, and a cranioplasty with bone cement. (J Korean Soc Traumatol 2007;20:52-56)

This paper describes the fabrication and characteristics of a NO sensor using ZnO thin film integrated 3C-SiC micro heater based on polycrystalline 3C-SiC thin film of operation in harsh environments. The sensitivity, response time, and operating properties in high temperature and voltages of NO sensors based SiC MEMS are measured and analyzed. The sensitivity of device with pure ZnO thin film at the heater operating power of 13.5 mW (300℃) is 0.875 in NO gas concentration of 0.046 ppm. In the case of Pt doping, the sensitivity of at power consumption of 5.9 mW (250℃) was 1.92 at same gas flow rate. The ZnO with doped Pt was showed higher sensitivity, lower working temperature and faster adsorption characteristics to NO gas than pure ZnO thin film. The NO gas sensor integrated SiC micro heater is more strength than others in high voltage and temperature environments.

Nonlinear time history analysis (NTHA) has become a considerable option for seismic design. For complex and irregular structures, a NTHA derives realistic displacement that leads to efficient seismic design. However, regions without sufficient earthquake records face issues when determining which earthquake is most suitable for their site condition. In this study, a selection method for design ground motion used in the nonlinear time history analysis was developed by correlating the fundamental period of buildings and the mean period of ground motions. From existing literature, the relationship between the maximum displacement and the fundamental period normalized to the mean period was determined. A total of 200 NTHA was performed to establish the relationship of reinforced concrete (RC) piloti-type structures by statistically correlating them between the fundamental period and the mean period with the maximum displacement. By statistical means from RC piloti structure’s NTHA distribution, the regression curve and the 70% confidence interval were derived. This correlation determined the period ratio range category where the earthquake’s NTHA displacements were compared to the pseudo displacement of the design spectrum method. For the suggested piloti prototype model, it was concluded that the period ratio of 0.75-1.5 was a category that could determine whether the earthquake’s NTHA displacement was greater or less than the linear elastic response spectrum method.
