행복은 인간이 추구하는 최고의 가치이자 선이다. 그러나 오늘날의 경영환경은 직원들에게 점점 더 많 은 자원을 요구하여 그들의 행복추구를 방해한다. 자원보존이론과 긍정정서의 구축 및 확장이론에 의하 면, 개인의 행복은 그들이 소유하고 있거나 획득할 수 있는 자원량에 비례하게 된다. 본 연구는 심리적 웰빙이라는 개념을 통해 조직 구성원의 행복을 살펴보고자 한다. 이 연구에서 저자는 먼저 심리적 웰빙의 정서적 측면과 자아실현적 측면을 구분한 다음, 목표 상황에 따라 이러한 측면이 어떻게 변화하는지 살펴 본다. 목표설정이론에 근거하여 목표달성을 위해 자기규제를 할 경우 이를 통해 자아실현적 측면의 심리 적 웰빙을 증진할 수 있지만, 동시에 상실되는 자원을 통해 정서적 웰빙이 침해될 수 있다. 목표가 불명확 할 경우 목표달성가능성이 줄어들어 개인은 회피적 자기규제를 통해 자원손실을 줄이게되고 이를 통해 정서적 웰빙을 보호하지만 자아실현적 웰빙은 감소할 수 있다. 본 논문은 또한 상사근접관리로 인한 강제 적 규제상황을 가정하여 조절효과를 확인하였다. 12개 조직의 데이터를 수집하여 통계적으로 검증하였다. 그 결과 목표의 난이도와 모호성은 직원의 자기조절 전략을 통해 심리적 웰빙을 변화시키며, 이러한 경향 은 상사근접관리에 의해 조절되는 것으로 나타났다. 그리고 심리적 웰빙의 이 두 가지 측면이 갖는 이론 적 및 실무적 시사점에 대해서도 논하였다.

본 연구는 원통형 종이포트 토마토 육묘시 Diniconazole의 처리방법이 도장억제 및 근권발달에 미치는 영향을 검토하기 위하여 수행되었다. 그 결과, 엽면적, LAR, 초장, 충실도, 생체중, RGR 및 R/S 에서 시험구간 유의한 차이를 보였다. 동일한 농도를 처리했을 경우, 근권부와 지상부의 흡수도 차이로 인해 저면관수가 엽면살포에 비해 도장억제에 효과적이었다. 저면관수는 엽면시비의 10분의 1의 농도만으로도, 20~30%정도의 동일한 도장억제 효과를 얻을 수 있었다. 디니코나졸 처리에의한 근권부 반응이 흥미로웠는데, 저면관수시 총근장, 근권부피, 평균 근경 및 근단수가 증가하였다. 특히, 0.3mm 이하의 초미세근이 감소하고 0.3~0.6mm의 세근이 증가하였다. 따라서 원통형 종이포트 육묘시 저면관수를 하는 것이 기존 엽면시비에 비해 사용량이 적으면서도 도장억제 및 근권부 활착률을 높힐 수 있을 것으로 판단된다.

현대의 경영환경에서 구성원의 행복은 조직의 목표 중 하나로 고려된다. 하지만 조직에서 구성원의 행 복은 규범적으로 추구되기 보다는 지속가능하게 추구되어야 한다. 구성원의 행복이 조직목표로 지속적으로 추구되기 위해서는 조직의 지속적인 성장이 필수적이며, 이에 본 연구는 심리적 웰빙을 중심변수로 삼아 구성원의 행복을 파악하고, 성과와의 관계를 규명하고자 한다. 그 과정에서 구성원의 참여와 자원소 모를 중심으로 사회적 태만과 직무열의를 주요 경로로 파악하고, 이에 영향을 미치는 상황적 요인으로서 임파워링 리더십의 영향을 확인한다. 국내의 12개 조직에 대한 333명의 개인수준 분석결과, 심리적 웰빙이 높은 구성원들은 사회적 태만에 적게 참여하고, 직무열의가 높아 성과와 조직시민행동을 높였다. 임파워링 리더십은 사회적 태만의 경로에만 유의하였다. 본 연구는 이론 전개와 실증분석을 통해, 사회적 태만 과 협력연구분야, 긍정조직행동론 분야와 리더십 분야에 기여하였고, 실무적 시사점을 밝혔다.

This study was conducted to evaluate the efficacy of mulberry cake mixed diet on larval growth of Protaetia brevitarsis. As a result of adding mulberry cake to oak fermented sawdust and mulberry fermented sawdust, the survival rate of P. brevitarsis larvae were higher than those of the control when mass rearing larvae. When fed oak fermented sawdust with 3, 5% and 10% of mulberry cake, the cumulative proportion of larvae over 2.5g was 92.9% at 65 days, 90.8% at 55 days, and 96.3% at 45 days after rearing at 25±1℃, respectively. When fed mulberry fermented sawdust with 3%, 5% and 10% of mulberry cake, the cumulative proportion of larvae over 2.5g was 86.2% at 85 days, 90.7% at 75 days, and 91.5% at 75 days after rearing at 25±1℃, respectively.

This study was conducted to evaluate the efficacy of mulberry leaf mixed diet on larval growth of Protaetia brevitarsis. As a result of adding mulberry leaves to oak fermented sawdust, the survival rate of P. brevitarsis larvae were higher than those of the control when mass rearing larvae. When fed oak fermented sawdust with 5%, 10% and 20% of mulberry leaves, the cumulative proportion of larvae over 2.5g was 93.1% at 65 days, 95.6% at 55 days, and 93.9% at 55 days after rearing at 25±1℃, respectively. Also, heavy metals were not detected in larvae of P. brevitarsis fed on mulberry leaves.

Insect killing fungus Beauveria bassiana has been widely studied as a biological control agent. However, many studies have been focused on lab or field-based management. Herein this work, comparison of three B. bassiana strains was investigated under a molecular level. The whole genome sequences of ERL836, JEF-007 were analyzed by PacBio (35.5 Mb of ERL836 and 36.5 Mb of JEF-007) and ARSEF2860 referenced from GenBank (33.7 Mb). To compare the three strains, virulence, thermotolerance and chemical resistance were assayed. The transcriptomes of non-infecting B. bassiana and infecting B. bassiana against western flower thrips were analyzed using RNA-seq. This work can provide that genome features, functions, morphology and gene expression could be different under the molecular level, even if in the same species.

Melon thrips, Thrips palmi Karny (Thysanoptera: Thripidae) is a worldwide polyphagous pest. The management of this pest have mainly relied on chemical agents. However, the overuse is harmful to the environment and results in insects resistance. Therefore, alternative eco-friendly control methods that have different mode of action, such as biological control, are necessary to overcome the current issue. In this study, we isolated entomopathogenic fungi from Korean soil, and characterized them via morphological and molecular techniques and pathogenicity assay against Tenebrio molitor larvae. The isolated fungi were screened for virulence against T. palmi under laboratory conditions and the results were used to establish a thrips-pathogenic fungal library. The highly virulent isolates were selected and further characterized for optimum culture conditions and application as biopesticide in the field.

The global biopesticide market was estimated to become about 4% of the total crop protection market in 2015, mainly due to variability of their efficacy, narrow spectrum or difficulties in long-term storage. Therefore, many people focus on overcoming these issues as a big trend. Suggested solutions include the investigation of synergy between microorganisms, the use of genetic engineering, improving the pesticide life shelf, etc. As a result, biopesticides market has grown by more than 17% over the last decade. In this context and aiming to develop new entomopathogenic fungi–based pest management tools, we constructed a fungal library by isolating insect pathogenic fungi from soil. A total of 581 isolates belonging to 35 species were isolated and characterized. Beauveria bassiana was the most abundant, representing 38.55% of the total strains, followed by Metharizium anisopliae (22.55%) and bubillosa (8.6). …% of the total isolates were highly virulent against Tenebrio molitor killing most of the treated insects in 2 to 3 days.

Japanese pine sawyer, Monochamus alternatus, is the main pest that mediates pine wilt nematode, Bursaphelenchus xylophilus, that causes serious damage to pine forests. In this study, we studied the strategy to control M. alternatus using entomopathogenic fungi. The fungi were collected from soil by an insect-baiting method and two fungal isolates (Metarhizium anisopliae JEF-197 and JEF-279) showed high virulence against M. alternatus. The Metarhizium isolates were evaluated for insecticidal activity against M. alternatus by spray treatment on live pine trees and wintering trees, and the M. anisopliae JEF-197 showed high insecticidal activity. In addition, the interaction of fungi and M. alternatus were analyzed by RNA-seq. This result can contribute to the development of insect control agents using entomopathogenic fungi.

Beauveria bassiana is widely studied for its potential as biopesticide. However, little is known about the factors to influence genetic diversity among isolates. In this work, we aimed to study the gene diversity of 42 isolates to figure out the impact of sequences variability on various biological features. The accumulated data showed no correlation between sequence variability and the fungal geographic localization. Meanwhile, weak to strong correlations have been obtained between the sequence diversity of various genes and the studied biological features. Interestingly, Biotrophy-associated gene 2 gene variability was correlated with all the studied biological features, being an important marker to determine isolates of interest for biological control. Therefore, the obtained data would serve as a database to focus on interesting genes related to improving or screening highly virulent isolates as biological control agents.
