Carbon molecular sieve (CMS) membranes were prepared by pyrolysis of polyimides having carboxylic acid groups and applied to the hydrogen separation. The polymeric membranes having carboxylic acid groups showed different steric properties as compared with polymeric membranes having other side groups (-CH3 and -CF3) because of the hydrogen bond between the carboxylic acid groups. However, the microporous CMS membranes were significantly affected by the decomposable side groups evidenced from the wide angle X-rat diffraction, nitrogen adsorption isotherms, and single gas permeation measurement. Furthermore, the gas separation properties of the CMS membranes were essentially affected by the pyrolysis temperature. As a result, the CMS membranes Prepared by Pyrolysis of polyimide containing carboxylic acid froups at 700℃ showed the H2 permeability of 3,809 Baller [1×10-10 H cm(STP)cm/cm2.s.cmHg], H2/N2, selectivity of 46 and H2/CH4 selectivity of 130 while the CMS membranes derived from polyimide showed the H2 permeability of 3,272 Barrer, H2/N2 selectivity of 136 and H2/CH4 selectivity of 177.

Polyvinylpyrrolidone을 포함하는 폴리이미드 전구체의 열분해 공정을 통해 탄소분자체막을 제조하였으며 열분해성 고분자를 포함하는 전구체를 통해 제조된 막의 구조 및 기체 투과 특성에 대해 연구 하였다. 열분해성 고분자를 포함하는 전구체의 열적 특성을 조사한 결과 열적으로 안정한 폴리이미드의 경우 550℃에서 분해되는 것을 확인할 수 있었으며 열분해성 고분자의 경우 400℃에서 분해가 시작되는 것을 TCA를 통해 확인하였다 제조된 탄소분자체막의 기체 투과 특성을 조사한 결과 최종 열분해 온도가 증가됨에 따라 기체 투과도는 감소하였으며 열분해성 고분자를 포함한 전구체로부터 제조된 탄소분자체막의 경우 기체 투과가 향상됨을 알 수 있었다. 열분해성 고분자를 함유하는 전구체로부터 550℃에서 열분해를 통해 제조된 탄소분자체막의 경우 O2 투과도 808 Barrer [10-10cm3 (STP)cm/cm2scmHg]과 O2/N2선택도 7을 나타내었다.

The characterization of detectors installed in space- and ground-based instruments is important to evaluate the system performance. We report the development of a detector performance test system for astronomical applications using the Andor iKon M CCD camera. The performance test system consists of a light source, monochromator, integrating sphere, and power meters. We adopted the Czerny–Tuner monochromator with three ruled gratings and one mirror, which covers a spectral range of 200–9,000 nm with a spectral resolution of ~1 nm in the visible region. Various detector characteristics, such as the quantum efficiency, sensitivity, and noise, can be measured in wide wavelength ranges from the visible to mid-infrared regions. We evaluated the Korea Astronomy and Space Science Institute (KASI) detector performance test system by using the performance verification of the Andor iKon-M CCD camera. The test procedure includes measurements of the conversion gain (2.86 e−/ADU), full well capacity (130 K e−), nonlinearity, and pixel defects. We also estimated the read noise, dark current, and quantum efficiency as a function of the temperature. The lowest measured read noise is 12 e−. The dark current at 223 K was determined to be 7 e−/s/pix and its doubling temperature is 5.3°C ± 0.2°C at an activation energy of 0.6 eV. The maximum quantum efficiency at 223 K was estimated to be 93 % ± 2 %. We proved that the quantum efficiency is sensitive to the operating temperature. It varies up to 5 % in the visible region, while the variation increases to 30 % in the near-infrared region. Based on the comparison of our results with the test report by the vendor, we conclude that our performance test results are consistent with those from the vendor considering the test environment. We also confirmed that the KASI detector performance test system is reliable and our measurement method and analysis are accurate.

This study aimed to analyze the effects of a horticultural occupation therapy program using a healing garden on the emotional rehabilitation of patients with acute and chronic mental disorders, and to identify the possibility of using horticultural occupational therapy as a mental rehabilitation service to promote the social rehabilitation of patients with mental disorders. In this study, 20 patients diagnosed as chronic mental disorder at Seoul Metropolitan E hospital and 22 as acute mental disorder at Incheon H hospital were divided into 2 groups for Horticultural occupation therapy (HOT) and Group occupational therapy (GOT). General occupational therapy was provided 4 times a week for the experimental groups of patients with chronic and acute mental disorders, and a horticultural occupational therapy program using a healing garden was provided only once a week, a total of 12 sessions, for the experimental groups. For the control groups of patients with acute and chronic mental disorders, occupational therapy was provided 5 times a week only. Among the acute mental disorder patients, the treatment group showed a significant decrease in Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and emotional stress scale (ES), whereas the control group didn’t (p<.001). On the other hand, such significant changes were not seen among the chronic GOT. Futhermore, the chronic HOT showed the significant effect in physical stress scale (PSE).

Background : Ramie, Boehmeria nivea (L) Gaud, is a bast fiber plant of the nettle family (Urticaceae) and originated in Asia. We have taken an active interest in ramie breeding for edible ramie, and consequently select "Yeonggwang No.1" with high yielding and good quality for edible leaves in 2015. Methods and Results : "Yeonggwang No.1" is a new ramie variety for edible leaves, which was derived from the plants of the population for pure clone isolation from 2013 to 2014, and progressively for specific character and yield trial in 2014 to 2015. The yield trials were carried on the field and the greenhouse with two replications, respectively. The plant height of "Yeonggwang No.1" is about 140 ㎝ with 6 ㎝ higher than that of check variety "Seobang" The leaves are heart-shaped, with large size, and finely serrated margins. The color of the upper side of the leaf is dark green, and silvery white on the under surface. The flowers are light purple in color and are borne in declinate clusters in the axils of the leaves. The average SLW (specific leaf weight) was 8.56 ㎎/㎠, which was weight lighter than that of check "Seobang", but chlorophyll content measured by a Chlorophyll meter, SPAD-502 was 12.3 SPAD higher than that of "Seobang". Fresh leaf yield was the annual total 1,578 ㎏/10 a in the field, and 2,479 ㎏/10 a in the greenhouse, which was 98% level of "Seobang" in the field, and increased by 10% than check "Seobang" in the greenhouse. The fresh leaves yield of "Yeonggwang No.1" tended to increased in changes according to time more than "Seobang". Conclusion : As a new variety, Yeonggwang No.1 can be harvested leaves several times annually, with the yield range of 1,578 – 2,479 ㎏/10 a, having 72.3% moisture, 6.61% crude protein, 987 ㎎ calcium, 5.27 Fe in its leaves. These results seem to indicate that there is considerable scope for increasing the fresh leaf yield of ramie and improving the processing quality by means of selection from the large and comparatively unexplored pool of variation, which should be obtainable from this heterozygous plant.

Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. In addition, the safflower buds (SB) were found to have more useful functional ingredients than safflower seed. Thus, we investigated the preventive effects of SB diet in ovariectomized (OVX) rats. The rats were divided into five groups; sham operated group, OVX alone group, OVX plus 17β-estradiol (E2 10 ㎍/㎏, i.p.) and OVX plus SB diet feeding group (0.3% or 1%). Feeding of SB diet (0.3% or 3%) to OVX rats markedly increased trabecular formation in femur compared to OVX rats. Feeding of SB diet (0.3% or 3%) to OVX rats also decreased TRAP activity compared to OVX rats. These results suggest that SB diets have bone sparing effects by the decrease of osteoclast activity. We also observed that OVX rats fed with SB diet (0.3% or 3%) exhibited the decrease of calcium and phosphorus in serum compared to OVX-induced rats. Therefore, SB may be beneficial for the patients of osteoporosis, especially in postmenopausal women.

Fusarium crown root rot (FCRR) is a severe fungal disease caused by Fusarium oxysporum f. sp. radicis-lycopersici (FORL) in tomato. Resistance to FORL is conferred by single dominant locus Frl on chromosome 9, but its precise genomic location is not clearly determined. In this study, detailed location of Frl was assessed by using a set of molecular markers physically anchored on Chr.9 and F2 and RIL population derived from FORL-resistant inbred AV107-4 (S.lycopersicum) x susceptible L3708 (S. pimpinellifolium). Bioassay of the two populations with a FORL strain isolated from Korea resulted in single dominant heritance of the resistance. Two SCAR and 11 CAPS markers encompassing 3.6Mb~72Mb of Chr.9 were developed from the Tomato-EXPEN 2000 map and SolCAP SNP-array analysis. These markers were genotyped on 345 F2 plants. A high level of cosegregation with the resistance were observed for 5 markers which were mapped at a large physical interval of 5.1Mb (T1212) to 46.4Mb (SSR237), indicating that genetic recombination was highly suppressed in this region. Cosegregation of these markers with Frl was confirmed by using 126 RILs. The results implied that, in contrast with the previously reported long arm, Frl is present on a pericentromeric region of short arm of Chr. 9, in which crossing-over is severely suppressed. The marker set was further tested on 12 FORL-resistance or susceptibility commercial cultivars. Unlike the biparental populations, frequent linkage break was observed for T1212 and D4 in commercial cultivars. T1212 and D4 showed 50% and 100% match with the phenotype, respectively. D4, a CAPS, was converted to a high resolution melting (HRM) marker and tested on 55 breeding lines from private seed companies (Fig.3). All breeding lines showed the HRM genotype for resistance allele, indicating that D4 can be useful for selecting FORL-resistance tomato plants.

In this study, enhancement of phosphorus and nitrogen recovery efficiency from livestock manure through Magnesium Ammonium Phosphate (MAP) crystallization method has been suggested as an alternative to solve the problems of the existing phosphorus resource recovery method. It can become a useful fertilizer. This study focused on improvement of phosphorus resource recovery by changing energy density of ultrasonic dose for MAP crystallization. Solubilization rate (as phosphate/phosphorus) of phosphorus in livestock manure was measured by ultrasonic treatment. The energy density range of 100-50,000 of ultrasonic dose was determined. Optimal ultrasonic energy density was 1,000 dose as 64.5% of phosphate ratio. However, when the higher than 1,000 dose of ultrasonic energy density did not more improve phosphate solubilization ratio. Consequently, when use ultrasonic treatment at 1,000 dose of energy density, the phosphorus could recover approximately 65% from livestock manure by MAP crystallization. Moreover, this MAP becomes more valuable due to its nature as a slow-release fertilizer.

Cereal seeds, sorghum, foxtail millet, hog millet, adlay, and corn are traditionally used as health assistant as well as energy supplying food in Korea. While beneficial phytochemicals to human have revealed in cereals, the information on peptides from cereals is far less accumulated than major reserve protein. Here, we analyzed peptide profiles using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF MS) in cereal seeds for construction of peptide information and attempted to develop peptide biomarkers for cereal identification. To optimize the analysis condition of SELDI-TOF MS, the effect of dilution factor on binding affinity to protein chips was tested using CM10 and Q10 arrays. Peptide clusters were significantly different at the level of 0.01 p-value. Peak spectra were the most stable in 1:50 of dilution factor in both chip arrays. Numbers of detected peak of 5 cereal seeds were 131 in CM10 and 74 in Q10 array. Each cereal was grouped as a cluster and well discriminated into different cluster in the level of 0.01 p-value. Numbers of potentially identified peptide biomarkers are 11, 13, 9, 5 and 12 in sorghum, foxtail millet, hog millet, adlay and corn, respectively. This study demonstrates that each cereal seed have own distinguishable specific peptides although their function are not identified yet in this study. In addition, the proteomic profiling using SELDI-TOF MS techniques could be a useful and powerful tool to discover peptide biomarker for discrimination and assess crop species, especially under 20 kDa.
