The objective of this research was to develop the adsorbent for heavy metals by activating the bark sample. Barks from pine tree with diameters of 2~4 mm were activated in the muffle furnace under a high relative humidity condition at temperatures of 600~900℃. The removal efficiency of the activated bark (ACTBARK) for Cu and Cd was temperature dependent showing the order of 900℃ > 800℃ > 700℃ > 600℃. The critical temperature was considered to be 900℃ to become an efficient adsorbent for Cu and Cd. The bark samples activated at temperatures lower than 700℃ showed a less removal efficiency than the crude bark The ACTBARK activated at 900℃ removed more Cu and Cd from solution than the commercial activated carbon and charcoal. The ACTBARK (activated at 900℃) adsorbed all of the Cu and Cd in solution with concentrations less than 150 mg/L. The selectivity of the ACTBARK was in the order of Cu>Zn>Ni>Pb>Fe>Cd>Mn.

수피 돈분 부산물 비료의 부숙단계별 특성 변화

박창진,김정제,양재의,용석호 한국환경농학회 1999 한국환경농학회지 Vol.18 No.4

본 연구는 부산물 비료의 부숙도 판정 기준 설정을 위한 기초자료를 구축하기 위하여 우리 나라에서 가장 널리 사용되고 있는 수피 부산물 비료와 돈분 부산물 비료를 대상으로 원재료로부터 완제품 생산까지 부숙단계별 시료의 물리적·화학적·생물학적 특성의 변화를 측정하기 위해 수행되었으며, 그 결과를 요약하면 다음과 같다. 부숙이 완료됨에 따라 tvl 부산물 비료의 경우 유색(black)으로, 돈분 부산물의 경우 암갈색으로 변화되었으며, 수피 부산물의 경우는 43일경과 후에, 돈분 부산물의 경우는 40일경과 후에 원 시료의 냄새가 사라지고 퇴비취가 나는 것으로 나타났다. 완숙된 수피 부산물 비료의 pH와 EC는 각각 pH6.5와 1dS·m^(-1)에서 안정화되었으며, 돈분 부산물 비료의 경우는 pH7.2와 6dS·m^(-1)에서 안정화되었다. 부숙이 진행됨에 따라 유기물함량은 점차 감소하여 수피 부산물 비료의 경우 120일 경과후 62%, 돈분 부산물 비료의 경우 40일경과 후 59%로 안정화되었다. 부숙 기간 중 총 질소의 함량은 수피 부산물 비료의 경우 1.1∼1.5%, 돈분 부산물의 경우 1.5∼2.2%를 유지하였다. 두 가지 비료 모두에서 암모니아태 질소는 초기에 증가하다 중기 이후 감소하였고, 질산태 질소는 계속적으로 증가하였으며, 무기태 질소의 전체 함량은 증가하였다. 부숙이 완료된 퇴비의 유기물/질소비는 수피 부산물 비료의 경우 25에서, 돈분 부산물 비료의 경우 27에서 안정화되었다. 부숙이 진행됨에 따라 CEC는 증가하였는데, 완숙단계에서 수피 부산물 비료의 경우 87cmol(+)·㎏^(-1)으로, 돈분 부산물 비료의 경우 70cmol(+)·㎏^(-1)으로 증가하였다. 조섬유 중 Cellulose와 Hemicellulose는 부숙이 진행됨에 따라 감소하였으나, Lignin의 비율은 점차 증가하였다. 부산물비료의 부숙단계별 시료의 특성변화는 부산물 비료의 부숙도를 평가하는 지표로 활용될 수 있을 것으로 판단된다. Objective of this research was to draw the basic criteria of the compost maturity evaluation., by assessing the stability of chemical and physical properties of the bark and piggery manure by-product composts during the composting. Colors of the mature composts were black and dark brown for the bark and piggery manure by-product composts, respectively. Good earthy odor was detected for both by-product composts after approximately 40 days composting, by which odors of the original raw materials were disappeared. pH and EC of the mature bark: compost were stabilized at 6.5 and 1dS/m, respectively. The respective values for the piggery compost were stabilized at 7.2 and 6dS/m. Organic matter contents were decreased with time to be stabilized at about 60% at the end of composting. During composting, total N contents of the bark and piggery composts were maintained at 1.1∼1.5%, and 1.5∼2.2%, respectively. For both fertilizers, NH₄-N contents were increased at the initial stage bur. decreased after the middle stages of decomposition, resulting in the increase of NO₃-N contents. Total inorganic N contents were increased with time. C/N ratios of both mature composts were stabilized at 25∼27. CEC of the bark compost was increased logarithmically with time and that of mature compost was 87cmol(+)/㎏. CEC of the piggery manure compost was hyperbolic function with rime and reached at 70cmol(+)/㎏ at the mature stage. Crude fiber analysis indicated that relative contents of lignin were increased with composting by compensating for the decreases of cellulose and hemicellulose contents.

Heat Shock Proteins: A Review of the Molecular Chaperones for Plant Immunity

박창진,서영수 한국식물병리학회 2015 Plant Pathology Journal Vol.31 No.4

As sessile organisms, plants are exposed to persistently changing stresses and have to be able to interpret and respond to them. The stresses, drought, salinity, chemicals, cold and hot temperatures, and various pathogen attacks have interconnected effects on plants, resulting in the disruption of protein homeostasis. Maintenance of proteins in their functional native conformations and preventing aggregation of nonnative proteins are important for cell survival under stress. Heat shock proteins (HSPs) functioning as molecular chaperones are the key components responsible for protein folding, assembly, translocation, and degradation under stress conditions and in many normal cellular processes. Plants respond to pathogen invasion using two different innate immune responses mediated by pattern recognition receptors (PRRs) or resistance (R) proteins. HSPs play an indispensable role as molecular chaperones in the quality control of plasma membrane-resident PRRs and intracellular R proteins against potential invaders. Here, we specifically discuss the functional involvement of cytosolic and endoplasmic reticulum (ER) HSPs/chaperones in plant immunity to obtain an integrated understanding of the immune responses in plant cells.

Establishment of Glucocorticoid-Mediated Transcriptional Induction of the Rice XA21 Pattern Recognition Receptor

박창진,Patrick E. Canlas,Pamela C. Ronald 한국식물학회 2012 Journal of Plant Biology Vol.55 No.1

The rice pattern recognition receptor, XA21,confers robust resistance to the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo). We have generated transgenic plants that express Xa21 only in the presence of the glucocorticoid hormone, dexamethasone (DEX). DEX-mediated transcriptional induction of Xa21 is accompanied by upregulation of pathogenesis-related 1 gene expression and restriction of Xoo multiplication. The DEXinducible system can be used to synchronize the XA21-mediated response to infection throughout the entire leaf,facilitating the study of innate immunity.

Structural Relationship among Job Satisfaction, Job Commitment, and Job Performance: A Comparative Study of Franchise vs. Local Coffee Store

박창진,이상묵,함성필 (사)한국조리학회 2019 한국조리학회지 Vol.25 No.2

This study was conducted to verify the relationships among job satisfaction, job commitment, and job performance from coffee shop workers who had working experience within three years. The survey was distributed in three major cities in South Korea using online method. Total 400 surveys were distributed and 350 participants were employed for further statistical analysing. SPSS 23.0 and AMOS 23.0 Statistical analysis tool was used for this study. The results shown that all of variables has significant relationships each other. The job satisfaction was specifically critical predictor of job commitment and performance in this study. In addition, there was significant connection between job commitment and job performance. In this study, moderating effect of types of coffee store has been conducted. The result of moderating effect reported that there was significant different relationship between job commitment and job performance. Specifically, the workers who worked for franchise coffee store recognized the job performance through job commitment than local coffee shop workers. In sum, this study will contribute to provide significant practical implications in both academia and the coffee shop business.
