This study was designed to evaluate the quality characteristics and antioxidant properties of Longanae Arillus powder (added in the ratios of 0%, 25%, 50%, 75%, and 100%), which is traditionally used to render the product more suited to the modern consumer's taste for the compound Longanae Arillus Dasiks. As the consumer consumption of the proportions of Longanae Arillus increases, the moisture content and pH of the Dasik supplemented with Longanae Arillus decrease, while at the same time, a soluble solid content increases (p<0.001). The color value showed the decrease in L and b values with the increase in Longanae Arillus content, and the increase in the value of the compound with the addition of Longanae Arillus (p<0.001) can be noted. The mechanical texture of Dasik was increased by the addition of Longanae Arillus considering its hardness, adhesiveness, cohesiveness, springiness, and chewiness (p<0.001). In the sensory evaluation of the Longanae Arillus Dasik showed that people expressed an overall preference at the addition of Longanae Arillus, such as noted as being preferred with 50% in color, flavor, taste, texture, and overall acceptance of the compound (p<0.001). Regarding the antioxidant activity of Longanae Arillus Dasik, the total phenolic, flavonoid contents, DPPH radical scavenging activity, reducing power, and superoxide anion levels were found to increase with the addition of Longanae Arillus (p<0.001) with its consumer use. It is believed that Longanae Arillus Dasik, is most preferred to be added at the concentration of 50% during the Dasik preparation.

내습성 및 감수성 선발계통 각 1점씩을 대상으로 침수처리 후 GO 분석을 통해 추출된 유전자들을 기능별로 분류해보면 생물학적 과정(biological process)에 관여하는 유전자 발현이 가장 크게 영향을 받았으며, 분자 기능(molecular function)과 세포 요소(cellular component) 관련 유전자를 포함하여 모든 기능의 유전자 발현 변화가 감수성 계통보다 내습성 계통에서 크게 일어났다. 침수처리 후 발현 양상이 유의하게 차이나는 유전자의 보다 자세한 기능을 측정한 결과 내습성 계통에서 발현량이 증가한 유전자는 CA02g26670은 CONSTANS protein과 관련있는 유전자로 일장조건에 따른 개화조절에 관여하는 유전자이며, 발현량이 감소한 유전자는 CA01g21450, CA01g22480, CA01g34470, CA02g00370, CA02g00380이었다. 감수성 계통에서 침수처리 후 발현량이 증가한 유전자는 CA02g09720, CA02g21290, CA03g16520, CA07g02110, CA12g17910이었는데 각각 단백질 분해효소 활성 저해, DNA binding, 세포벽 분해효소 억제, nodulin 관련 유전자 등으로 밝혀진 유전자들이었다. 감수성 계통에서 발현량이 감소한 유전자는 CA02g02820, CA03g21390, CA06g17700, CA07g18230로 각각 칼슘이온결합, 고온환경 발현기작, 레시틴 생합성 경로의 수용성중간대사체인 phosphocholine 합성 및 저온스트레스 관련 등의 기능을 한다. 내습성 계통과 감수성 계통에서 동시에 발현이 증가한 유전자는 고온 등 환경스트레스로 인한 apoptosis와 관련된 유전자와 peroxidase와 관련있는 유전자로 확인되었고, 발현이 동시에 감소한 유전자는 nucleoside transporter인 CA02g16990로 확인되었으며, 나머지 선발 유전자는 유전자 발현이 확인되지 않았다. 내습성 및 감수성 계통간 습해 조건에서 발현에 차이를 보이는 유전자 구명을 기반으로 향후 불량환경에 대해 저항성을 보이는 계통 육성 및 관련 생리반응에 대한 다양한 연구가 필요하다. This study was conducted to select pepper lines that were tolerant to excessive water injury among the pepper germplasm and investigate the genetic characteristics of those lines to contribute to the breeding of pepper cultivars with stable productivity in abnormal weather. Each of the tolerant and susceptible lines went through immersion treatment, and differentially expressed genes between them were analyzed. The tolerant line showed increased expression of the CA02g26670 gene, which is involved in the CONSTANS protein pathway and regulation of flowering by day length, but it exhibited decreased expressions of CA01g21450, CA01g22480, CA01g34470, CA02g00370 and CA02g00380. The susceptible line showed increased gene expressions of CA02g09720, CA02g21290, CA03g16520, CA07g 02110, and CA12g17910, which are involved in the inhibition of proteolytic enzyme activity, DNA binding, inhibition of cell wall-degrading enzyme, and inhibition of nodulin, respectively. Meanwhile the expressions of CA02g02820, CA03g21390, CA06g17700 and CA07g18230 decreased in the susceptible line, in relation to calcium-ion binding, high temperature, synthesis of phosphocholine and cold stress, respectively. The expressions of genes related to apoptosis and peroxidase increased, while that of CA02g16990, which functions as a nucleoside transporter, decreased in both the tolerant and susceptible lines. Based on the different gene expressions between the tolerant and susceptible lines, further studies are needed on breeding abiotic stress-tolerant lines.
순환식 수경재배시 무기이온 조절이 Single-Node Cutting 장미의 양분흡수, 생육 및 품질에 미치는 영향
양은영(Eun Young Yang),박금순(Keum Soon Park),오정심(Jeong Sim Oh),이혜진(Hye Jin Lee),이용범(Yong-Beom Lee) (사)한국생물환경조절학회 2008 시설원예‧식물공장 Vol.17 No.4
본 실험은 장미 식물공장에서 single-node cutting 'Versillia'의 양분흡수 특성을 구명하고 순환식 수경재배 시스템에 적합한 배양액 내 무기이온 조절방식을 구명하고자 수행하였다. 실험 기간동안 각 처리별 배양액 내 무기이온함량 변화를 살펴본 결과 EC 제어구의 경우 NO₃-N은 생육 후반이 되면 그 함량이 적정 범위 이상으로 증가하였고 P와 Mg은 감소하였으며 배양액 첨가구는 전체적인 배양액 내 무기이온 함량이 증가하였다. 이에 비해 무기이온 제어구는 생육 기간동안 근권 내 적정 범위를 유지하였다. 광합성 효율을 나타내는 지표 중 하나인 Fv/Fm는 무기이온제어구와 배앙액 첨가구에서 높았고 절화장, 생체중 등은 무기이온 제어구에서 높았다. 그러나 뿌리의 활성 정도를 측정해본 결과 무기이온 제어구에서 높았으나 배양액 첨가구에서는 생육 초기에 배양액 내 pH 변화폭이 커서 가장 낮게 나타났다. 위의 결과를 종합하였을 때, 무기이온 조절(다량·미량원소 제어구와 다량원소 제어구)을 통해 배양액을 관리하는 것이 생육 전 기간 동안 근권 환경을 적절히 유지해 줄 수 있었고 이에 따라 절화품질도 향상 되므로 장미(single-node cutting) 순환식 수경재배에 적합한 근권 환경 제어방식이라고 할 수 있다. This study was conducted to observe the characteristics of mineral nutrient uptake of singlenode cutting rose 'Versilla' and to determine optimal nutrient solution control method for soilless culture of 'Versilla' in a closed hydroponic system. Nutrient solution was managed by five different control methods: macro- and micro-element control in aeroponic system (M&M), macroelement control in aeroponic system (M), nutrient solution supplement in aeroponic system (S); electrical conductivity (EC) control in aeroponic system(EC-A); EC control in deep flow technique system(EC-D). The concentration of NO₃-N exceeds optimal range whereas P and Mg decreased at the later stage of plant growth with the EC control method, EC-A and EC-D. The overall mineral nutrient content increased with S. On the other hand the nutrient content at the root environment was maintained optimal with M&M and M. The nutrient solution control methods had significantly effect on the cut-flower quality. In the M&M and M, flower length, fresh weight and root activity were higher than those with the other mineral nutrients control methods. The maximal efficiency of photochemistry (Fv/Fm) was higher for M&M, M and S than that with EC-A and EC-D. Based on the above results, it is highly recommended to control nutrient solution by mineral nutrient control methods (M&M and M) in a closed hydroponic system for single-node cutting rose, 'Versillia'.

This study originated from the recognition that, while design competitions are the typical method for commissioning designs for public architecture projects, attention to subsequent stages is crucial to fulfill the competitions ultimate intent. Survey results from both clients and designers underscored the importance of internalizing the initial project plan regarding construction cost and duration. Continuous research considering the characteristics and life cycle of public building projects is necessary to establish basic data, such as reference cases and type-specific standards. Additionally, theres a need to rationalize current price standards and period calculation methods for architectural design work, and to establish a basis for smooth operation by specifying design change work and various procedures during the architectural design stage. Ensuring smooth communication among project participants and a consistent project management system is vital. Moreover, understanding the public building project process from a collaborative perspective and forming a common understanding of roles and responsibilities is essential. By verifying primary participants perceptions-clients and designers regarding changes throughout various project stages, this research underscores the need for systemic and academic improvements. The findings are expected to provide foundational data for future studies aiming to ensure rationality in post-design competition processes.
