본 연구는 학원구성원의 욕구수준과 직무환경이 직무만족 및 직업정체성에 미치는 영향요인을 파악하는 것을 목적으로 하였다. 연구 결과를 토대로 학원구성원의 직업정체성을 제고시킬 수 있는 방안을 모색하고 학원교육의 교육적 기능을 강화시키는데 도움이 되고자 하였다. 연구 목적을 달성하기 위하여 학원구성원을 대상으로 설문조사(395명)와 심층면 담(12명)을 수행하여 자료를 수집하였다. 본 연구의 주요 결과는 다음과 같다. 첫째, 학원구성원의 욕구수준에서는 생리적 욕구가, 직무환경에서는 학생환경이, 직무만족에서는 직무자체 만족이, 직업정체성에서는 자율성에 대한 신념이 높게 나타났다. 둘째, 학원구성원의 개인배경 에 따라 욕구수준, 직무환경, 직무만족, 직업정체성에 대한 인식은 차이가 있는 것으로 나타났다. 셋째 학원구성원의 직 무만족에 영향을 주는 요인은 존경의 욕구, 자아실현의 욕구, 원장환경, 동료환경, 시설환경, 업무환경이고, 직업정체성에 영향을 주는 요인은 생리적 욕구, 애정소속의 욕구, 자아실현의 욕구, 직무만족인 것으로 나타났다. 결과적으로 학원 차원에서는 학원구성원의 욕구수준을 고려한 인사관리와 직무환경에 대한 개선을 통해 학원구성원의 직무만족 및 직업정체성을 제고시키기 위해 노력해야 하고, 학원구성원 차원에서는 전문성 향상 및 사명감 제고를 통해 직업정체성을 높이는 노력이 필요하다.

Background : Obesity, a global health problem and a chronic diseases, is associated with increased risk of developing type 2 diabetes and coronary heart diseases. A wide variety of natural remedies have been explored for their obesity treatment potential. To elucidate the anti-obesity effect of ginsenoside Rg5 : Rk1 (Rg5 : Rk1), a mixture of protopanaxadiol type ginsenosides isolated from Panax ginseng Meyer in a 3T3-L1 adipocytes. Methods and Results : In order to determinate the anti-obesity effect of Rg5 : Rk1, Oil Red O staining and triglyceride (TG) content was assessed. Furthermore, to elucidate the possible mechanism whether Rg5:Rk1 affects lipid accumulation, mRNA and protein expression analyses of adipocyte markers such as STAT3, PPARγ, CBEPα and ap2 were carried out. Rg5:Rk1 treatment showed an inhibition of lipid droplet accumulation and decrease on TG content. In addition, expression of STAT3, PPARγ, CEBPα and ap2 were decreased in dose dependent manner. Similar to these results, Rg5:Rk1 treatment reduced PPARγ and CEBPα protein expression. Conclusion : Rg5 : Rk1 treatment exhibits anti-adipogenic activity by down-regulation of the STAT3PPARγ/CEBPα pathway in 3T3-L1 adipocyte cell line.

This study investigated the prevalence of total aerobic bacteria, coliform and food poisoning (Bacillus cereus) bacteria in commercial Jeotgal for the evaluation of microbiological safety. The mean mass of total aerobic bacteria was 4.8±1.4 log CFU/g in Jeotgal. Coliform was detected in 17 (48.6%) of 35 seasoned Jeotgal; 14 (42.4%) of 33 low salted Jeotgal compared with three (16.7%) of 18 general salted Jeotgal; and in three (37.5%) of eight HACCP certificated Jeotgal compared with 14 (32.6%) of 43 non-HACCP certificated Jeotgal. Bacillus cereus was detected in two (12.5%) of 16 non-seasoned Jeotgal compared with 20 (57.1%) of 35 seasoned Jeotgal; in 19 (57.6%) of 33 low salted Jeotgal compared with three (16.7%) of 18 general salted Jeotgal, and in four (50.0%) of eight HACCP certificated Jeotgal compared with 18 (41.9%) of 43 non-HACCP certificated Jeotgal. Overall, our results showed that coliform and B. cereus contamination was highest in the seasoned and low salted Jeotgal. It is necessary to improve the microbiological safety low salted and seasoned Jeotgal. The HACCP system in Jeotgal is reconfirmed for the enhancement of microbiological safety.
