폴리에스테르 섬유 감량시스템의 제어를 위해서는 처리조 내에서 감량되는 섬유가 목표 감량치에 도달했는지를 판단해 주는 장치가 필요하다. 본 연구에서는 가성소다용액의 초농도 및 섬유 감량 정도의 정확한 측정과 감량 종료시간의 산출 및 이에 따른 종료신호를 발생할 수 있는 폴리에스테르 섬유 감량기 전용의 자동적정장치를 개발하였다. To control caustic soda treatment system for the polyester fabric reduction, we need the device to determine that the fabric has been arrived target reduction value. In this study, we develope an automatic process titrator for the caustic soda treatment system. Major functions of the target titrating system are accurate measurements of the caustic soda concentration and then producing the end point signal for caustic soda treatment system.

The study was carried of out to investigate the effects of water on the fermentative characteristics of the mixed and needed dough and the quality of white pann bread produced by using of Distilled water(DW), Mineral water (MW) and Hot spring water(SW). The results of the characteristics of dough and the quality of white bread measured were as the follow. 1. Mineral water showed higher swelling in the fermentation processing but it was lower in the loaf volume at the baking stage. 2. In the quality, the loaf volume of baked bread made by using of Mineral water and Hot spring water was higher then Distilled water. 3. The measured hardness of baked bread made by using of Distilled water was lower then Mineral water and Hot spring water As the result of this quality test, the white bread made of Mineral water and Hot spring water was showed excellent result.

The studies about automatic pattern detection of the eye and face from the human image acquired by the CCD image sensor have good applicabilities in the industry, home automation, and data communication field. In general, pattern detection method consists of feature based matching and template matching. In feature based matching, the feature vector is extracted with DLM(dynamic linking matching), EBGM(elastic bunch graph matching), HMM(hidden markov model) matching and knowledge based matching using statistical characteristics. In template matching, in general, the template vector is extracted with PCA(principal component analysis). When these method applied in the face and eye detection, each method has its own merits and some disadvantage. Therefore, by combined utilization of SVD(singular value decomposition) and HMM algorithm, is expected that we can selectively make use of each methods advantage and it result in improved detection accuracy. In this paper, we proposed the method for face and eye detection, which was combined by the two algorithms, to be suitable for the high speed image processing using DSP chip or microprocessor. In the beginning, template matching was followed by a template extraction using batch SVD algorithm and then face pattern was classified and recognized by HMM algorithm which is one of feature based matching technique. Finally, eye pattern detection was performed by pattern search neural network utilizing eigeneye image.

Ketyl radical formation of excited 1, 8-naphthalimides in protic polar solvent

Cho, Dae Won,Cho, Dae Won,Park, Hea Jung,Yoon, Ung Chan,Lee, Myoung Hee,Im, Chan Korean Society of Photoscience 2012 Rapid communication in photoscience Vol.1 No.2

Photoinduced electron-transfer process of 1,8-naphthalimide-linker-trimethylsilane (NI-O3-TMS, O3 = 3,6,9-trioxaundecyl) and NI-O3 has been investigated using the transient absorption measurements in $CH_3CN$ and $CH_3CN/H_2O$. The excitation of NI-O3-TMS in $CH_3CN$ produced the NI radical anion ($NI^{{\cdot}-}$) with a transient absorption band around 413 nm, via the intermolecular electron-transfer between NI moieties in the excited singlet state. In contrast, in a protic polar solvent mixture of $CH_3CN/H_2O$, a proton abstraction process occurred from $NI^{{\cdot}-}$ to generate the NI ketyl radical ($NIH^{\cdot}$), which showed a transient absorption band around 405 nm. The decay time constants of $NIH^{\cdot}$ were quite long compared to those of $NI^{{\cdot}-}$ in $CH_3CN$.

Objectives: The objective of this case report was to investigate the effect of Korean medicine therapy on migraine patients with typical aura. Methods: Acupuncture and chuna manual therapy were applied to outpatients once in 1 to 2 weeks, a total of 9 times, for about 11 weeks. A patient was diagnosed with ganyang-toutong and taeeumin dry-heat symptomatic pattern. Herbal medicine (Chongsanggeontong-tang Gagambang (淸上蠲痛湯加減方)) was prescribed for 15 days up to the 3rd visit, then another herbal medicine (Yeoldahanso-tang (熱多寒少湯)) prescribed for 15 days up to the 6th visit. MSQol and MIDAS were used as a tool at the start and after 9th treatment. The intensity and frequency of headache, frequency of aura and neck pain were examined on every visit. Results: According to the results, Korean traditional medicine described above had effect on the intensity and frequency of headache, frequency of aura and neck pain as well as an increase in the figure of MSQoL from 62 to 81 and decrease of MIDAS Disability from 18 to 7, Duration from 60 to 30, Pain score from 8 to 2. Conclusions: Migraine with typical aura classified as ganyang-toutong and taeeumin dry-heat symptomatic pattern can be alleviated by Korean traditional medicine.

Stiripentol is an anti-epileptic drug for the treating of refractory status epilepticus. It has been reported that stiripentol can attenuate seizure severity and reduce seizure-induced neuronal damage in animal models of epilepsy. The objective of the present study was to investigate effects of post-treatment with stiripentol on cognitive deficit and neuronal damage in the cornu ammonis 1 (CA1) region of the hippocampus proper following transient ischemia in the forebrain of gerbils. To evaluate ischemia-induced cognitive impairments, passive avoidance test and 8-arm radial maze test were performed. It was found that post-treatment with stiripentol at 20 mg/kg, but not 10 or 15 mg/kg, reduced ischemia-induced memory impairment. Transient ischemia-induced neuronal death in the CA1 region was also significantly attenuated only by 20 mg/kg stiripentol treatment after transient ischemia. In addition, 20 mg/kg stiripentol treatment significantly decreased ischemia-induced astrocyte damage and immunoglobulin G leakage. In brief, stiripentol treatment after transient ischemia ameliorated transient ischemia-induced cognitive impairment in gerbils, showing that pyramidal neurons were protected and astrocyte damage and blood brain barrier leakage were significantly attenuated in the hippocampus. Results of this study suggest stiripentol can be developed as a candidate of therapeutic drug for ischemic stroke.

Growth Characteristics of Fruiting Body in Lentinus edodes (‘Nongjingo’) by Relative Humidity

Chan Young Kim,Chang Ho Kim,Hea Young Jeng,Tae Kwon Kim,Myoung Hak Lee,Yong Koo Cho,Tae Seok Oh,Myoung Jun Jang 한국버섯학회 2017 버섯 Vol.21 No.1

This research was relative humidity (65, 75, 85 and 95%) growth characteristics of the oak mushroom (Lentinula edodes) 'Nongjingo’. At the relative humidity was 65% in growth chamber. On this condition the moisture content of medium surface was 60.5%. That was lower than other treatments. That condition makes Pileus was 77.1% and stipe was 65%. Among the growth characteristics according to the relative humidity, the pileus diameter at 75% relative humidity were 45.5mm that largest than other treatment and pileus thickness at 75% relative humidity were largest than other treatment. The stipe thickness at 65% relative humidity were 14.8mm that lagest than other treatment. The number of available stipes at 95% relative humidity were 13.3peace/2kg that largest than other treatment. The comparison yield ability of 1 cycle was 104.2g that result in largest than other treatment at 95% relative humidity. This result was associated to the relative humidity of fruiting bodies, the lower relative humidity result in the lower of yield. However, the lower relative humidity result in the higher number of whago, Especially, at the treatment of 65% relative humidity, all the fruit bodies were produced as Whago (dry). Therefore, the higher relative humidity influenced in the higher yield but produced water mushroom. That result was thought that ‘Nongjingo’ would be possible to produce high quality mushroom by adjusting the relative humidity appropriately.
