조직내 대인 신뢰의 중요성에도 불구하고, 조직내 대인 신뢰를 높이기 위한 선행요인과 효과성을 다룬 연구가 미흡한 실정이다. 그러므로 조직내 대인 신뢰의 선행변수로써 고몰입 인적자원관리(신중한 선발, 교육훈련, 성과관리, 고용 안정성, 퇴직관리)의 영향을 살펴보고, 결과변수로써 근로자의 생산성 향상 행위에 미치는 효과를 살펴보았다. 그리고 조직내 대인 신뢰가 근로자의 생산성 향상 행위에 미치는 효과를 협력적 노사관계 인식이 조절하는지에 대해서 살펴보았으며, 나아가 전체 모형의 통합적인 관점에서 조절된 매개효과를 살펴보았다. 본 연구의 실증분석을 위해, 국내 기업 재직 근로자 400명을 대상으로 설문조사를 진행하였고, 회수된 설문지 중 성실히 응답한 총 341명의 자료를 대상으로 실증분석을 하였다. 가설의 검증을 위해 회귀분석과 부트스트래핑을 이용한 PROCESS macro 분석을 실시하였다. 본 연구의 결과는 첫째, 고몰입 인적자원관리는 조직내 대인 신뢰에 긍정적인 영향을 미치는 것으로 나타났으며, 둘째, 조직내 대인 신뢰는 근로자의 생산성 향상 행위에 긍정적인 영향을 주는 것으로 나타났다. 셋째, 고몰입 인적자원관리와 근로자의 생산성 향상 행위의 관계를 조직내 대인 신뢰가 매개하고 있음을 밝혔다. 넷째, 협력적 노사관계 인식은 조직내 대인 신뢰와 근로자의 생산성 향상 행위의 관계를 긍정적으로 조절하는 것으로 나타났으며, 마지막으로 고몰입 인적자원관리가 조직내 대인 신뢰를 거쳐 근로자의 생산성 향상 행위에 미치는 간접효과에 대해서도 협력적 노사관계 인식은 조절된 매개효과를 가진 것으로 나타났다. 끝으로, 본 연구 결과의 이론적ㆍ실무적 시사점에 대해서 논의한다. Despite the importance of interpersonal trust in organizations, little attention has been paid to the antecedents and consequences of interpersonal trust in organizations. Thus, we suggest high commitment human resource management practices (selective recruitment, education and training, performance management, job security, and retirement management) as a antecedent of interpersonal trust in organizations, and investigate how interpersonal trust in organizations affects employees’ productivity-enhancing behavior. We also examine whether the relationship between interpersonal trust in organizations and employees’ productivity-enhancing behavior is moderated by the degree of perceived cooperative industrial relations, and ultimately advance a moderated mediation effect of perceived cooperative industrial relations. To test our suggested hypotheses, a total of 400 questionnaires were distributed to employees in Korean firms, but 59 of them were incomplete, leaving 341 completed samples for data analysis. Regression analysis and the PROCESS macro for SPSS were employed to test the suggested hypotheses. Our results show that first, high commitment human resource management is positively related to interpersonal trust in organizations. Second, interpersonal trust in organizations positively affects employees’ productivity-enhancing behavior. Third, we find that interpersonal trust in organizations is an important intervening variable between high commitment human resource management and employees’ productivity-enhancing behavior. Fourth, the relationship between interpersonal trust in organizations and the outcome variable is positively contingent on the level of perceived cooperative industrial relations. Finally, we find strong support for a moderated mediation effect on the conditional indirect effect of cooperative industrial relations. We discuss the theoretical and practical implications of our findings.

Objectives: Ojeok-san (OJS), an oriental herbal formula, has been used in Asian countries including Korea, China and Japan to treat the common cold and illnesses including fatigue and gastrointestinal disorders. The purpose of this study was to examine the anti-obesity effect and molecular mechanism of OJS, on adipogenesis in 3T3-L1 cells. Also, the effects of OJS in obese mice fed a high-fat diet on adiposity were examined. Methods: Preferentially, we analyzed the component of OJS and measured the stability of its component in OJS according to study periods using high performance liquid chromatography (HPLC). In vitro, 3T3-L1 cells were treated with OJS (50 to 200 μg/mL) during differentiation for 8 days. The accumulation of lipid droplets was determined by Oil Red O staining. The expressions of genes related to adipogenesis were measured by RT-PCR and Western blot analyses. For anti-obesty effect in vivo, we experimented for 8 weeks with four group (normal diet (CON), high-fat diet (HF), high-fat diet with OJS (HF+OJS) and high-fat diet with Bang-pung-tong-sung-san (HF+BTS) in comparison group HF+OJS). Results: OJS showed inhibitory activity on adipocyte differentiation at 3T3-L1 preadipocytes without affect cell toxicity as assessed by measuring fat accumulation and adipogenesis. In addition, OJS significantly reduced the expression levels of several adipocyte marker genes including proliferator activated receptor-γ (PPAR-γ) and CCAAT/enhancer-binding protein-α (C/EBP-α). Also OJS-administered mice showed significant inhibitory of body weights and abdominal adipose tissue weights. Conclusions: This study showed that traditional medicine OJS has an anti-obesity effect in vitro and in vivo. Thus, OJS could be developed as a supplement for reduction of body weight gain induced by an obesity.

Objectives : Daesiho-tang (DSHT) has been widely used in the treatment of cerebral infarct in traditional medicine. However, there was not report on the anti-obesity-related diseases efficacy of DSHT. In this study, we investigated the effects for the new formulation of DSHT, on the adipocyte differentiation cycle in 3T3-L1 cells. Methods : 3T3-L1 cells were treated with DSHT (50, 100, 200 ㎍/㎖) during differentiation for 6 days. Also, the inhibitory effect of DSHT against 3T3-L1 adipogenesis was evaluated in various stage of adipogenesis such as early (0-2day), intermediate (2-4day), and terminal stage (4-6day). The accumulation of lipid droplets was determined by Oil Red O staining. and, the expressions of genes related to adipogenesis were measured by RT-PCR and Western blot analyses. Results : DSHT showed inhibitory activity on adipocyte differentiation at 3T3-L1 preadipocytes without affect cell toxicity as assessed by measuring fat accumulation and adipogenesis. In addition, DSHT significantly reduced the expression levels of several adipocyte marker genes including proliferator activated receptor-γ (PPAR-γ) and CCAAT/ enhancer-binding protein-α (C/EBP-α). Also, the anti-adipogenic effect of DSHT was strongly limited in the intermediate (2-4 day), terminal stage (4-6 day) of 3T3-L1 adipogenesis. In addition, the DSHT treatment down- regulated mRNA expression levels of PPAR-γ,, C/EBP-α in mature 3T3-L1 adipocytes. Conclusions : These results suggest that, the ability of DSHT has inhibited overall adipogenesis and lipid accumulation in the 3T3-L1 cells. The new formulation of DSHT may be a promising medicine for the treatment of obesity and related metabolic disorders.
