  • It is generally known that the temple structure in Korea was formalized by the ceremonial principle based on the Buddhist cosmology. But, there have been no concrete studies on how far the two have relationship with each other and what significance it implies in it. In other words, even though the temple structure reflects the Sumeru Mount cosmology which is the Buddhist cosmology, there is still uncertain aspects in the relationship between them. This research is a more concrete approach on what kind of corelation the Sumeru Mount cosmology has with the Korean temple structure. For this, the levels of related documents on the Buddhist cosmology and the Sumeru Mount cosmology have been arranged first. Then, on this basis, it is searched with what symbolism the cosmology has been accepted in the temple structure. The temple is a sacred space that holds Buddha and a profane space which the sattva (ordinary people) can approach at the same time. The site of the temple is also a land that is connected to the residence of sattva and a blissful area of prayer that they can be born again through Buddha at the same time. Thus, the double characteristics of sanctity and profanity are finally inter-connected with each other in the view point of Jinsokburi(Truth and Worldliness are not different), and the temple structure reflects this significance through the symbolism very well. Therefore, the correct recognition on the temple structure can be said as an important aspect to understand the purpose of Buddhism.

  • To increase the device linearities and the breakdown-voltages of FETs, $Al_{0.25}$G $a_{0.75}$As/I $n_{0.25}$G $a_{0.75}$As/A $l_{0.25}$G $a_{0.75}$As partially doped channel FET(DCFET) structures are proposed. The metal insulator-semiconductor(MIS) like structures show the high gate-drain breakdown voltage(-20V) and high linearities. We propose a partially doped channel structure to enhance the device linearity to the homogeneously doped channel structure. The physics of partially doped channel structure is investigated with 2D device simulation. The devices showed the small ripple of the current cut-off frequency and the power cut-off frequency over the wide bias range. bias range.

  • The purpose of this study was to determine the effect of IPBC(3-lodo-2-propynylbutylcarbamate) on dandruff caused by the anthropophilic fungus Malassezia furfur. The effects of IPBC on dandruff were examined by evaluating (a) the MIC value of IPBC using broth dilution method; (b) the remnant antimicrobial activity of IPBC containing shampoo on skin disc; (c) the antidandruff efficacy of 1.0 % IPBC containing shampoo in double blind clinical trial. To investigate the remnant antimicrobial activity of IPBC against Malassezia furfur, guinea pig-skin disc was washed with antidandruff shampoo and then the diameter of inhibition zone per disc was measured. For clinical trial, thirty healthy volunteers, aged 25-35, participated in 4 week study. At 0, 2, 4 weeks, examinations of scaling, itching on scalp were carried out. The MIC(Minimun Inhibition Concentration) values of IPBC range from 0.10 to 1.00${\mu}g/ml$ and it seems that IPBC is more effective in the MIC values than zinc pyrithione, selenium disulphide, piroctone olamine and comparable to ketoconazole, climbazole. When the remnant antimicrobial activity of IPBC shampoo on skin disc was determined, 0.5% IPBC shampoo and 2.0% Ketoconazole shampoo resulted in similar antimicrobial effect. In addition, 1.0%, 2.0% IPBC shampoo was more effective than 2.0% ketoconazole shampoo. After two and four-weeks of 1.0% IPBC shampoo treatment, there was significant reduction of scaling, itching in test group compared to control group. On the basis of these results, it can be concluded that 1.0% IPBC is more effective than 2.0% Ketoconazole in reducing dandruff. It seems that strong capacity of drug binding to the stratum corneum plays a role in its antidandruff effect since adsorption of active ingredients on scalp is very important factor in reducing dandruff.

  • Background and Objectives : To determine the changes of reflux symptoms and laryngoscopic findings of patients with laryngopharyngeal reflux (LPR) on the duration of proton pump inhibitor medication. Materials and Methods : From Feb 2003 to Nov 2004, 58 patients who were diagnosed with LPR by 24-hour double-probe pH monitoring were enrolled. All patients were treated with proton pump inhibitor and followed up for 8 weeks at least. The response of symptoms and laryngoscopic findings of patients were assessed with reflux symptom index (RSI) and reflux finding score (RFS) before treatment and 2, 4, 8, 12, 16, 20 weeks after treatment. Results : The symptoms of patients with LPR were improved significantly at 2, 4, 8 weeks of treatment. The laryngoscopic findings of patients with LPR were improved significantly at 4 and 12 weeks of treatment. There was no correlation between improvement of reflux symptoms and laryngoscopic findings. Conclusions : The laryngoscopic findings of LPR patients were improved more slowly than reflux symptoms. Based on our results, anti-reflux therapy might be continued at least for 3 months until the improvement of laryngoscopic findings.

  • Winter dormancy of the mulberry(Morus species) in Suwon was investigated with regards to mulberry varieties, such as Kaeryangppong, Daeryunppon, Yongchionppong and Hongolppong application of fertilizers and growth hormone. In general, It initiated at late September and it subsequently became deeper and reached the highest degree through late October to early November. After that early November it gradually turned into the breaking state and was terminated by late November. Intensity and duration of dormancy were lower and shorter in Kaeryangppon. The standard application of N. P. K(30-13-18kg/10a) affects it delayed, but terminated earlier. On the other hand, the double amount of nitrogen affects the dormancy fast, but terminated late. The treatments of GA3 at the early and termination stages increased the bad sprouting. The contents of RNA and protein in the bark gradually increased as the dormancy becomes deeper.

  • The influence of water salinity on the hydraulic conductivities of compacted bentonites with several dry densities were studied. The hydraulic conductivity increases with increasing salinity only when the dry density of bentonite is relatively low. The degree of increase becomes more remarkable at a lower dry density of bentonite. For bentonite with the density of 1.0 $Mg/m^3$ and 1.2 $Mg/m^3$, the hydraulic conductivity of the 0.4 M NaCl solution increases up to about 7 times and 3 times, respectively higher than that of freshwater. However, for the bentonite with a dry density higher than 1.4 $Mg/m^3$, the salinity has an insignificant effect on the hydraulic conductivity, and the hydraulic conductivity is nearly constant within the salinity range of 0.04 to 0.4 M NaCl. The pre-saturation of the bentonite specimen with freshwater has no significant influence on the hydraulic conductivity.

  • Double-layered Al-Mg films have been deposited by using an e-beam deposition method on a cold-rolled steel sheet(CR), which the structure of the film was Al/Mg/CR. The micro-structure, alloy phase, and corrosion resistance of the Al-Mg coated CR were investigated before and after heat treatment at $400^{\circ}C$ for 2, 3, and 10 min in a nitrogen atmosphere. Total thickness of Al-Mg films was fixed at $3{\mu}m$ and the thickness ratio of Al and Mg layers(Al:Mg) has been changed from 5:1 to 1:5. The cross-sectional morphology of the films, which had the thickness ratio of 2:1(Al:Mg), 1:1, and 1:2, was changed after heat treatment from columnar to featureless structure. The x-ray diffraction data for as-deposited films showed only pure Al and Mg peaks. Al-Mg alloy peaks such as $Al_3Mg_2$ and $Al_{12}Mg_{17}$ phase appeared after the heat treatment. The Al-Mg coating with the thickness ratio of 1:1(Al:Mg) showed the best corrosion resistance of up to 500 hours by salt spray test.

  • 화학저항식(Chemiresistive) 가스센서의 저항변화를 향상시키기 위해서는 센서 소재의 비표면적을 향상시키는 방향 및 전자천이를 증가시키는 방향으로 연구가 진행되어야 하며, 그 중 센서의 비표면적을 향상시키는 예로써 중공 나노섬유가 있을 수 있다. 본 연구에서는 비표면적의 향상뿐만 아니라 중공 나노섬유의 전자천이를 증가시켜 센서의 검출 성능을 더욱 향상시키기 위한 목적으로 $TiO_2/ZnO$ 이중층 중공 나노섬유를 제안하었다. 제안된 $TiO_2/ZnO$ 이중층 중공 나노섬유는 템플레이트 합성법을 통해 제작되었으며, 그 공정은 다음과 같다; 전기방사(Electrospinning) 공정을 통해 폴리머 나노섬유를 제작한 후 $TiO_2$ 층과 ZnO 층을 ALD(Atomic Layer Deposition) 공정을 통해 차례대로 증착시킨다. 그 후 후열처리 공정을 통해 코어 폴리머를 제거함으로써 $TiO_2/ZnO$ 이중층 중공 나노섬유를 얻을 수 있다. 이 때, ZnO 층의 두께는 각각 달리하여 제작되었으며, 최종적으로 이들에 대한 가스 센싱 특성 및 메커니즘에 대한 체계적인 조사를 진행하였다. 단층 중공나노섬유는 셀 층의 두께가 Debye length와 유사할 때 셀 층 표면이 완전공핍층이 형성되고, 그 보다 크게 되면 부분적인 공핍층이 형성되게 되어 감응도가 감소하게 된다. 그러나 이중층 중공 나노섬유의 경우 셀 층의 두께가 Debye length 보다 더 크게 되더라도 TiO2와 ZnO의 헤테로접합으로 인해 ZnO에서 TiO2로 전자의 이동을 야기시키게 되어 환원성 가스에 대한 감응도가 단층 ZnO 중공 나노섬유에 비해 향상되게 된다.

  • In this study, the shapes of po worn by military officers who served During the period of Japanese Invasion of Korea(1592-1598) were investigated. Findings of the study can be summarized as follows. Various types of po that military officers usually wore during the period of Japanese Invasion of Korea includes jikryeong, dapho, dopo, cheolik, aekjureum, jangeui, jungchimak and bangryeongpo. Out of these types, cheolik and jungchimak were most often used by the officers. Po that were usually worn by military officers during the period of Japanese Invasion of Korea as above mentioned is characterized as no difference in length between the front and back of the costume, kalgit and a pair of coat strings which are directly attached to po. The sleeves of the costume are bean chaff-shaped in some cases and just narrowly shaped in other cases. Similarly, the outer seop of po was either double-layered or single-layered. For jikryeong and dapho, mu is usually type of outside wrinkle. For dopo, its rear kit has the inner hem whose right and left edges are usually distant, respectively by 6~16cm, from the back center of the costume. Cheolik and aekjureum usually have either fine or broad pleats. For jangeui and jungchimak, mu is usually trapezoid in shape. Among various types of po which were usually worn by military officers during the period of Japanese Invasion of Korea, most representative are jikryeong from the tombs of Bae Cheon jo, dapho from Shin Yeo Gwan, dopo from general Bak and Bae Cheon Jo, cheolik from Nam Yoo and Cho Gyeong, aekjureum from Shin Yeo Gwan, jangeui from Kim Ham, jungchimak from Bae Cheon jo and bangryeongpo from Cho Gyeong.
