공공기관 조직 구성원의 긍정심리자본과 조직공정성이 직무 재창조에 미치는 영향에 대한 연구
황은진 한국공기업학회 2022 공기업논총 Vol.22 No.1
본 연구의 목적은 직무 재창조 이론에 기반하여 공공기관 구성원의 직무 재창조가 향상될 수 있는 요인을 파악하는 것이다. 연구 목적을 달성하기 위해 공공기관 A기관의 구성원을 대상으로 설문조사를 실시하였고, 총 204명의 응답을 수집하였다. 설문을 바탕으로 조절된 매개효과 모형을 이용하여 분석하였다. 분석 결과, 공공기관의 긍정심리자본과 직무재창조는 정(+)의 관련이 있었다. 또한, 조직공정성이 이들의 관계를 매개하여 더욱 강화하는 결과를 나타냈다. 한편, 긍정자본심리와 조직공정성 간 세대의 조절된 매개효과는 밀레니얼 세대의 상호작용적 공정성이 높을수록 직무 재창조가 강화되는 것을 발견하였다. 본 연구는 분석 결과를 바탕으로 긍정자본심리와 직무 재창조의 관계, 조직공정성의 효과, 밀레니얼 세대 효과등에 대하여 HRD관점에서 실천적 시사점을 제시하였다.

The purpose of this study was to investigate the physiological effects of exercise high-intensity down-hill running on immune function and inflammatory responses at mid-follicular phase(MF) and mid-luteal(ML) phase in eumenorrheic and healthy women in twenties. Subjects were random assigned was performed twice during about 120 min including resting 30 min, down-hill running 30 min, recovery 1h during two different phases of the menstrual cycle: MF (8-11 days after menstruation) and ML(6-9 days before menstruation). females completed 30 min down-hill running by–17.6% at 70% of maximal oxygen consumption (VO2max) after resting and Tympanic temperature, Heart Rate(HR), Rating of Perceived Exertion(RPE), Delayed onset muscle soreness(DOMS) during test. Blood samples were assessed pre-exercise, immediately post-exercise, 24 h post-exercise, Complete blood cell count (CBC), CK, LDH, CRP, IgG, Cortisol was measured. Condition x time interaction were analyzed by repeated measure ANOVA, There was a significantly different between condition on change in RPE (p<.05) and change in WBC, CRP concentrations in interaction (p<.05). The result of this study indicate that women perceived exercise-intensity in MLl more than MF, WBC that appeared all high in ML indicates possibility that high-intensity exercise in ML may be induce increase of inflammatory reaction and muscle damage as high level of inflammatory markers. In addition, CRP levels were rapidly increased at Post-24h in ML, however, It was not level which can heighten the risk of cardiovascular disease because it was inside normal figure. Though women was attention to increase in muscle soreness and inflammation protein by inflammatory reaction when exercise in ML.
리더와 구성원의 역할 기대 상호일치성과 자기결정성이 리더십 교육훈련에 미치는 영향
황은진,문명 한국공공관리학회 2023 한국공공관리학보 Vol.37 No.1
This study empirically analyzed the relationship between the perception of the necessity of leadership education and training, the intention to participate in education, and role expectation and motivation. The influence of organizational members on the level of perception of the necessity of leadership education and training and participation intention was analyzed by classifying them into amotivation, intrinsic, and external motivation of self-determination. For analysis, a survey was conducted on public enterprises. The relationship between factors was analyzed using binary logit analysis and ordered logit analysis. The results of the study were summarized as follows. First, the gap in perception of role expectation was found through a t-test between the supervisor's role oneself and the supervisor's role perceived by the subordinates. Second, both the perception of the necessity of leadership education and training and the intention to participate in education are influenced by amotivation and intrinsic motivation. Third, this study analyzed that the intention to participate in education had a great influence on relational factor. In other words, this study would suggest we should focus on the need to enhance the relational competence between supervisors and subordinates, or colleagues in order to convert the members' awareness of the need for education to actual participation in education. 본 연구는 리더십 교육훈련 필요성 인식과 교육 참여 의도를 높이기 위한 영향요인을분석하고자 한다. 이를 위해 기대역할 상호일치 정도와 자기결정성 동기를 포함하여 분석하였다. 기대역할을 분석하기 위해 역할을 사고적 역할, 과업적 역할, 관계적 역할로분류하였고, 자기결정성의 동기는 무동기, 내재적 동기, 외재적 동기로 나누어 분석하였다. 분석을 위해 공기업의 관리자를 대상으로 설문을 실시하였고, 이항로짓분석과 순서형로짓분석을 활용하여 요인 간 관계를 분석하였다. 연구 결과를 요약하면 다음과 같다. 첫째, 리더십 교육훈련 필요성 인식과 교육참여 의도 모두 무동기와 내재적 동기의영향을 받는다. 둘째, 교육참여 의도는 관계에 대한 기대역할이 큰 영향력을 미치는 것으로 분석되었다. 마지막으로 구성원의 교육 필요성 인식도를 실질적인 교육 참여 의도로 전환시키기 위해서는 상사와 부하 혹은 동료 간 관계의 제고 필요성을 시사한다.
시설재배 쑥갓 및 피망의 작물특성에 따른 Boscalid 및 Spinetoram의 잔류량 감소추이

BACKGROUND: This study was performed to evaluate the residue dissipation of boscalid and spinetoram on crown daisy and sweet pepper affected by the morphology of the crop. The half-lives and dissipation rate constants for boscalid and spinetoram on crown daisy and sweet pepper were calculated. And then lower limit of 95% confidence interval for dissipation rate constant could be used to propose the pre-harvest residue limit. METHODS AND RESULTS: The pesticide products diluted according to the pesticide label were applied one time on crown daisy and sweet pepper at 2 field sites, respectively. Initial concentration of boscalid and spinetoram on crown daisy after application were in the range of 72.80~117.15 mg/kg and 2.82~4.67 mg/kg, respectively. And Initial concentration of boscalid and spinetoram on sweet pepper were in the range of 1.58~1.62 mg/kg and 0.10~0.21 mg/kg, respectively. Boscalid and spinetoram for crown daisy dissipted below the maximum residue limit(MRL) at 10 and 2 days after application, respectively. All residues concentration of boscalid and spinetoram for sweet pepper below the MRL at 0 day after application. The half-lives based on dissipation rate constant for boscalid and spinetoram on crown daisy were 4.2~4.9 days and 3.0~2.4 days respectively. And the half-lives for boscalid and spinetoram on sweet pepper were 6.7~7.0 days and 2.8~4.0 days respectively. CONCLUSION: The difference in initial concentration of boscalid and spinetoram among crop commodities were due to different crop morphology with larger surface areas. This study was suggested that pre-harvest residue limit would be calculated from lower limit of 95% confidence interval for dissipation rate constant and would be useful to protect consumers by controlling the pesticide residues in crop.
