  • Cinnamoyl ester(PGEFC) of poly(phloroglucinol-formaldehyde) glycidyl ether which has photosensitive functional group was prepared to apply to photoresist. Photosensitivity of PGEFC was estimated by the solubility difference in organic solvent before and after exposure to light. The yield of residual film was calculated by immersing the sample-coated quartz plates in the solvent which was used in coating. The yield of the residual film which was closely related to the sensitivity of the film, was affected by the degree of polymerization of the backbone resin, sensitizers and their concentration. The sensitivity was depended upon the degree of polymerization. Most of effective sensitizer for PGEFC among the sensitizers was 2, 6-dichloro-4-nitroaniline.

  • In this paper, we investigate the behavior and sensitivity analysis of a solution set for a parametric generalized multi-valued nonlinear quasi-variational inclusion problem in a real Hilbert space. For this study, we utilize the technique of resolvent operator and the property of a fixed-point set of a multi-valued contractive mapping. We also examine Lipschitz continuity of the solution set with respect to the parameter under some appropriate conditions.

  • Background & Object : The aim of this study was to investigate the usefulness of electrogastrography on differential diagnosis of deficiency or excess Condition in patients with functional dyspepsia Methods : Selected symptoms for diagnosis of deficiency and excess in functional dyspepsia have been reviewed in some literatures, notably within Oriental medicine, Donguibogam and Gogeumdoseojipseong-uibujeolrok. This is what was investigated in this study. 93 patients (male 32, female 61) were divided into three groups; Non-pain group, Pre-treatment pain group (chief complain was abdominal pain at the first medical examination), and Mid-treatment pain group(they had no pain at the time of first medical examination, but showed abdominal pain within two weeks). 10 healthy people participated as normal controls. Gastric motility were recorded and analyzed using electrogastrography during fasting and postprandial period. In assessment, effectiveness was divided into validity, sensitivity and specificity. Results : Epigastric pain reflected the tendency for excess condition in comprehensive diagnosis, which was linked with postprandial arrhythmia in electrogastrography(p=0.001). Postprandial arrhythmia detected abdominal pain with a validity of 78.6%, a sensitivity of 79.2%, and a specificity of 78%(p<0.001). Conclusions : Results 1Tom Postprandial arrhythmia in electrogastrography support that the index of excess condition in the comprehensive diagnosis of symptoms is useful for patients with functional dyspepsia.

  • 공황장애 환자에서 12주간의 escitalopram 약물치료 결과, 공황장애 증상은 관해 상태에 이르렀고, 높은 불안민감도와 삶의 질 저하 및 기능장애가 모두 유의하게 호전되었다. 하지만 공황장애 환자들은 약물치료 후에도 여전히 상대적으로 높은 불안민감도와 삶의 질 저하 및 기능장애를 보여서 이의 회복을 위해서는 장기간의 약물치료가 필요할 수 있겠다.

  • HPPD 효소를 저해하여 카로티노이등 생합성을 억제하는 최근에 등록된 제초제 benzobicyclon 및 mesotrione+pretilachlor에 대한 통일형(장립종) 및 일반벼(단립종)간 약해 발생 차이 및 수량영향을 조사한 결과는 다음과 같다. 1. 제초제 MP 및 bezobicyclon에 대한 약해 반응은 벼 생태형에 따라 달랐는데 통일형 벼인 한아름벼, 한아름2호, 다산벼는 대부분 약해인 백화증상이 나타났으나 일반형인 주남조생, 일미벼, 주남벼는 약해증상을 거의 보이지 않았다. 제초제 별로는 MP가 benzobicyclon보다 초기에 약해발생이 심하였으나 후기에는 차이가 없었다. 통일형 벼는 제초제 처리 후 5일부터 백화증상을 보였고 10일에 약해증상이 뚜렷하였으며 처리 후 20일에는 약해증상이 처리 후 10일 보다 약해지는 경향이었다. 제초제 처리에 따른 카로티노이드 합성은 백화현상과 비슷하게 butachlor 대비 MP 처리가 benzobicyclon처리보다 초기에 더 억제가 되었으나 후기에는 차이가 없었다. 3. Benzobicyclon 및 MP 처리에 대한 약해로 통일형벼의 출수기가 butachlor 처리보다 3일가량 지연되었고, $m^2$당 수수가 11~50개가 적고 등숙비율이 0.9~7.5% 낮아져 쌀 수량은 benzobicyclon 처리가 7~10%, MP처리는 3~5% 감수하였다. 4. 하지만 일반형 품종은 benzobicyclon 및 MP를 처리해도 출수기, 벼 생육특성 및 쌀 수량은 butachlor처리와 차이가 없었다.

  • Now in the 21st century, all the industries in our world are rapidly changing, including fashion trends and customers' needs as well. Fashion textile planning is also developing towards the direction where it could satisfy the merged sensitivity and incentive of the customers through an idea. The purpose of this study is to accentuate the importance of fashion material planning in fitting conventional patterns and eco-benign fabric materials. Accordingly, this study is mainly focused on the reflection of fabric planning characteristics to show tradition containing comfort and naturalness. As mixing with established fabrics and blending with natural/functional fabrics, and conforming to the trend of the seasonal fabric, it has developed a new structure and pattern by changing the basic source of traditional patterns to a computer aided design system. Therefore, four different types of items were basically up-graded by fitting it in with traditional patterns.

  • 본 논문에서 제안한 능동 여파기는 커패시터를 사용하지 않고 단지 4개의 저항과 2단의 연산 증폭기로 구성되고 다기능 특성을 갖고 있으며 저항의 비를 낮춘 능동-R 여파기이다. 제안된 능동-R 여파기는 여파기 파라미터인 극점 주파수 $W_r$와 극점$Q_r$의 감도가 매우 낮으며 고주파에서의 동작이 가능하고 사용한 저항의 수가 적어지고 저항의 비가 감소하므로 여파기의 집적화가 용이하다. 실험을 통하여 제안된 능동-R 여파기의 모든 특성이 이론과 거의 일치함을 확인하였다.

  • The electronic structure, optical spectra, and thermodynamic properties of the three FOX-7 polymorphs (${\alpha}$, ${\beta}$, and ${\gamma}$) have been studied systematically using density functional theory. The LDA (CA-PZ) and generalized gradient approximation (GGA) (PW91) functions were used to relax the three FOX-7 phases without any constraint. Their density of states and partial density of states were calculated and analyzed. The band gaps for the three phases were calculated and the sequence of their sensitivity was presented. Their absorption coefficients were computed and compared. The thermodynamic functions including enthalpy (H), entropy (S), free energy (G), and heat capacity ($C_p$) for the three phases were evaluated.

  • Correct localization of epileptogenic zone is important for the successful epilepsy surgery. Both ictal perfusion single photon emission computed tomography (SPECT) and interictal F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) can provide useful information in the presurgical localization of intractable partial epilepsy. These imaging modalities have excellent diagnostic sensitivity in medial temporal lobe epilepsy and provide good presurgical information in neocortical epilepsy. Also provide functional information about cellular functions to better understand the neurobiology of epilepsy and to better define the ictal onset zone, symptomatogenic zone, propagation pathways, functional deficit zone and surround inhibition zones. Multimodality imaging and developments in analysis methods of ictal perfusion SPECT and new PET ligand other than FDG help to better define the localization.
