본 연구는 〈오버워치〉를 통해 고수준의 플레이어가 되는 과정에서 게임 내 협력을 위한 희생이 어떻게 수행되는가에 대해 살펴보았으며 주요 결과는 다음과 같다. 첫째, 낮은 경쟁전 점수대에서는 칭찬카드가 공격형-딜러와 지원형-힐러간에 차이가 크게 나타났으며 지원형에게 많은 칭찬카드가 부여되었다. 둘째, 플레이어의 점수가 높아질수록 힐러로부터 딜러에게로 칭찬카드가 더 많이 부여되었다. 셋째, 고점수대의 플레이어들이 힐러역할을 자발적으로 맡음으로써 ‘자애로운 역할’을 자임하며 팀의 규범을 선도했고 결과적으로 팀 내에서 발생할 수 있는 역할 갈등의 위험을 분산했다. 이로부터 점수대가 높을수록 협력이 강해짐을 확인하였다. This study looked into how to carry out sacrifices for intra-game cooperation in becoming a high-level player. The results are as follows. First, the way players behave is dependent on their resources(scores). Second, the higher the player’s score, the more praise cards were given to dealers. Third, high-scoring players have taken on a role of “sacrificing the self to serve the many” by voluntarily playing the role of healer, leading the team to set the rules and consequently reducing the risk of a probable role conflict within the team.

직무상에서 요구되는 특정 정서표현 규칙에 따라 정서를 조절하여 표현하는 과정을 정서노동이라 한다. 본 연구는 정서노동과 개인이 직무 중에 경험하는 정서경험이 밀접한 관련이 있다는 전제하에 정서노동 전략과 종업원이 경험하는 정서와의 관련성을 살펴보고, 정서노동 전략 사용이 직장에서 체험하는 정서와 함께 직무탈진과 이직의도를 설명하는 데 추가적으로 유의한 영향력을 갖는지를 검증하였다. 고객을 직접 상대하는 금융업계의 종업원 315명의 설문 응답을 분석한 결과, 부적 정서는 표면행위와, 정적 정서는 내면행위와 유의미한 상관을 나타냈다. 또한 표면행위 전략은 직무탈진과 정적 상관, 내면행위 전략은 직업효능감과 부적 상관을 나타냈다. 위계적 회귀분석 결과, 체험 정서에 부가적으로 표면행위는 직무탈진을, 내면행위는 직업효능감을 유의하게 예측하였다. 이러한 결과는 어떠한 정서조절 전략을 사용하는지가 경험하는 정서와 독립적으로 종업원의 직무탈진과 직업효능감에 영향을 미친다는 것을 시사한다. 이러한 연구결과의 시사점과 제한점을 논의하였다. The literature has demonstrated that emotional labor, a process of emotional regulation wherein workers are expected to display a certain type of emotion as a part of their jobs, has important implications for individual and organizational outcomes. The current study examined whether emotional labor has a unique impact on work attitudes. Even after controlling for state affect, analysis of survey data collected from 315 bank employees showed that emotional labor and state affect have independently significant influences on the job burnout and job engagement. Specifically, surface acting was significantly related to burnout even after controlling for negative affect, and deep acting was signifIcantly related to job engagement even after controlling for positive affect. However, after controlling for negative affect, surface acting was not found to be significantly related to turnover intention. Implications and suggestions for future research are also described in this thesis.

In this study, anti-inflammatory active compounds of Artemisia princeps, as a cosmetic raw material, were identified. Furthermore, anti-inflammatory active compounds and volatile flavor compounds contents variation by various deodorization were investigated. The 3,4-di-O-caffeoylquinic acid, jaceosidin, and eupatilin were reduced significantly NO production and proinflammatory mediators, such as iNOS, COX-2, PGE2, IL-1β, IL-6, and TNF-α, production in a concentration dependent manner. Deodorization process extracts were 65% EtOH re-extract that removed essential oil by SFE and 65% EtOH extracts respectively treated active carbons, bentonites, clay acids, GSP-07, 25, and 50. Among these deodorization process, the 65% EtOH re-extract that removed essential oil by SFE was increased 3,4-di-O-caffeoylquinic acid, jaceosidin, and eupatilin contents because essential oils and compounds were removed excluding anti-inflammatory active compounds. Dried Artemisia princeps, 65% EtOH Artemisia princeps extract and 65% EtOH Artemisia princeps extract treated deodorization were analyzed variation on volatile flavor compounds. The major volatile flavor compounds reported were removed in 65% EtOH Artemisia princeps extract treated deodorization, excluding caryophyllene oxide and α-terpineol. As a result, 65% EtOH re-extract that removed essential oil by SFE suggests that it is the most efficient deodorization process which had economic efficiency of using essential oils, high anti-inflammatory active compounds contents and reduction of volatile flavor compounds.

Red Chinese cabbage is rich in anthocyanins, with beneficial effects on anti-obesity and lipid profiles. The purpose of this study was to examine the anti-obesity effects of red Chinese cabbage. Four-weeks old Spague-Dawley male rats were divided into four groups for six weeks as follow: Normal Diet (ND), High Fat Diet (HFD), HFD + Red Chinese Cabbage Diet (RCD), HFD + Red Chinese Cabbage Juice (RCJD). After six weeks, the liver weight was significantly higher in the HFD group than in the other groups, and the RCD and RCJD groups showed similar values to the ND group. The epididymal fats were significantly higher in all high fat diets (HFD, RCD, RCJD) than in the ND group and there was statistical significance in the post-tests when comparing the RCD and RCJD groups with the HFD group. Triglycerides significantly decreased in the RCD group. In conclusion, red Chinese cabbage is rich in anthocyanins, with beneficial effects on organ weight and lipid profiles.

Objectives : We evaluated the relationship of the psychopathology, quality of life and perception of treatment goal in patients with cancer. Methods : A sample of 102 cancer patients completed both Hospital Anxiety and Depression Scale(HADS) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30(EORTC QLQ C-30). We compared the differences of the psychopathology of patients according to perception of treatment goal by chi-square test and evaluated risk factors for palliative perception of treatment goal by multiple logistic regression. We exhibited t-test to compare HADS and EORTC QLQ C-30 and the association between HADS and EORTC QLQ C-30 was analyzed by Pearson correlation analysis. Results : Of 102, 25 cancer patients had the psychopathology(HAD-T ≥19), including 21 for anxiety(HAD-A ≥8), 59 for depression(HAD-D ≥8). The association between HADS and EORTC QLQ C-30 was negatively correlated with statistical significance. Patients with depression and severe psychopathology showed statistically significant tendency to perceive treatment goal as palliative. Depression and metastasis were risk factors for palliative perception of treatment goal. Conclusions : Psychopathology and quality of life in patients with cancer is important for perception of treatment goal. Assessment and intervention to improve psychological distress and quality of life is warranted during all periods of cancer treatment.

We determined the resistance rates of pathogenic bacteria isolated from cultured olive flounder Paralichthys olivaceus to erythromycin (Em), antibiotic typically used in aquaculture and analyzed the genotypes of resistant bacteria using polymerase chain reaction (PCR). We isolated and utilized 160 isolates of Streptococcus parauberis, 1 of S. iniae, 66 of Edwardsiella tarda, 56 of Vibrio sp. and 23 of unidentified bacteria from presumed infected olive flounder from Jeju Island from March 2016 to October 2017. Of the 306 isolated strains, Em-resistant strains included 33 of S. parauberis, 39 of E. tarda and 2 of Vibrio sp. We conducted PCR to assess the resistance determination of Em-resistant strains. Five different types of Em-resistance genes were detected in the 74 Em-resistant strains: erm (A), erm (B), erm (C), mef (A) and mef (E); erm (A) and erm (B) were detected in 1 (3%) and 24 (72.7%) S. parauberis isolates, respectively. In E. tarda, erm (B) was detected in five isolates (12.8 %) and no Em-resistance genes were detected in the two Vibrio sp. isolates.
