Rheological properties of the aqueous solution of various polysaccarides and their effects as a stabilizer in fruit(peach) syrup and yogurt were investigated. Four kinds of modified starch(Sun Kolguard, Sun Registar, Mira Cleer 340 and Maps 449), three types of carrageenan(kappa, iota and lambda types) and pectin were used in this study. The 5% aqueous solution of each modified starch was gelatinized at $66^{\circ}C$. After gelatinization, Sun Kolguard showed the highest viscosity among those samples. The synergistic effect of carrageenan on 5% aqueous solution of Sun Kolguard was studied by changing the mixing ratio, and the result showed that the ratio 90:10(Sun Kolguard:carageenan) had the maximum synergistic effect and the effect of iota type carrageenan was higher than that of other types. The effect of Sun Kolguard as a stabilizer in fruit syrup were superior to other modified starches studied. The gelatinization temperature of the addition of iota carrageenan in starch added fruit syrup changed from $66^{\circ}C$ of 5% aqueous solution to $82^{\circ}C$. Furthermore, the viscosity after cooling of syrup which made iota carrageenan and starch added fruit syrup was more increased than simple starch added fruit syrup. The mixture of 90% Sun Kolguard and 10% iota carrageenan were estimated as the most appropriate stabilizer for manufacturing the fruit syrup and yogurt adding fruit syrup.

Sedum kamtschaticum has been used as one of the native valuable plants for ornamental purpose. This experiment was conducted to find out the optimum media for pot cultured Sedum kamtschaticum using peatmoss and coir-based mixtures. Four mixtures such as peatmoss:perlite(5:5, v/v), peatmoss:perlite(7:3, v/v), coir:perlite(5:5, v/v), and coir:perlite(7:3, v/v) were used. Plants were irrigated with a Sonneveld solution in an ebb & flow system. The content of T-N, K, and Ca in the peatmoss-based media was higher than those of the coir-based media. The concentration of T-N, K, and Ca in the shoots of Sedum kamtschaticum increased when plants were cultured with peatmoss-based media. In the peatmoss-based media, plant growth, such as number of branches, leaf length and shoot fresh and dry weights, were significantly increased than those of plant grown in the coir-based media. As the results, the optimum media for pot cultured Sedum kamtschaticum in an ebb & flow system was considered to be the peatmoss-based mixtures.

This study investigate growth responses of Chinese cabbage and nitrogen use efficiency (NUE) to application of fermented organic fertilizer produced from domestic organic resources for developing alternative materials instead of imported castor oil meal. Two types of fermented fertilizers (Fermented Organic Fertilizer A (OFA) and Fermented Organic Fertilizer B (OFB)) were produced by mixing distillers dried grains 30%, sesame cake 30%, rice bran 20% and fish meal 20% under different fermentation conditions. Treatment consisted of OFA is fermented for 21 days on plastic greenhouse, OFB is fermented for 5 days on 40℃, and MOF (Mixed Organic Fertilizer) is a fertilizer made with castor bean as the main ingredient. OFA, OFB and MOF were applied at the rate of 320 kg N/ha. Chinese cabbages were cultivated from Aug. to Nov. in 2022. Growth and yield of Chinese cabbage were no significant differences among all treatments except control (non-fertilized, NF). However, NUE of Chinese cabbage was higher the fermented fertilizer treatment (OFB: 81.4%, OFA: 79.1%) than the MOF (65.3%). It was observed that urease activity in the fermented fertilizer treatment was significantly higher than the MOF. This result confirmed that fermented fertilizers have similar effect on growth and yield with the MOF and could improve the NUE of crop.

Based on mixed-mode transient analyses utilizing a 2-dimensional device simulator, we have suggested the methodology to analyze the HBM ESD phenomena in CMOS chips utilizing NMOS transistors for ESD protection, and have analyzes the HBM discharge mechanisms in detail. Also the second breakdown characteristics in the protection device have been successfully simulated based on mixed-mode simulations, to explain the discharge mechanisms leading to device failure. To analyze the effects of the device structure changes on the discharge characteristics, we have compared the results of DC analyses and mixed-mode transient analyses, and have discussed about more robust designs of NMOS transistor structures against HBM ESD based on the analyses.

본 연구에서는 미얀마, 베트남, 일본에서 외부문명의 영향을 받은 것으로 여겨지는 정령숭배의 특징에 대하여 논하고자 한다. 우선, 각 국가의 전승을 비교해볼 때 정령숭배에 있어서 충격적인 상황 속에서 사망한 이들에 대한 신앙이 중요하다는 점을 지적하였다. 다음으로 정령의 형성에 있어서 정치적 역할이 개입되었다는 사실을 논하였다. 마지막으로 종교 혼합주의는 성(性, gender)과 관련되어 있음을 주장하였다.

This study was performed to extract rice protein from milled rice that is either lodged or unlodged, in order to prepare composite films by mixing the protein with curdlan or ${\kappa}$-carrageenan (3:0, 2:1, 1.5:1.5, 1:2, 0:3), and to compare the physical properties of the films. In the case of rice protein/curdlan composite films, tensile strengths increased with increasing curdlan content but water vapor permeabilities decreased, while, elongations showed a maximum at a mixing ratio of 1.5:1.5. In the case of rice protein/${\kappa}$-carrageenan composite films, tensile strengths increased with increasing ${\kappa}$-carrageenan content but elongations decreased, while water vapor permeabilities showed no tendency. Overall, there were no significant differences in the physical properties of composite films between lodged rice and unlodged rice.
