. This study examines the historical background of deforestation focusing on the process leading to the exploitation of forest resources, the decline of forest areas, and wood fuel shortage caused by the growth of the glass-making industry. In addition, it examines the meaning and function of forests, looking at the forest not only as a place where the violence of imperialism and colonialism is deeply traced, but also as a place which is gendered as a woman in the Tempest. Next, it examines how Ariel, set in a role of a spirit in the play, is related to deforestation, and as an example of deforestation it looks into the parts that Caliban and Ferdinand are forced to cut and carry wood under the pressure of an absolute monarch, Prospero. Lastly, ecological concerns in the play are closely related to post-colonial and feminist concerns in that this study deals with deforestation and the voices of Ariel which are not mentioned in the post-colonial and feminist views concerning the Tempest, but it does not entirely deny the elements of post-colonialism and feminism in the play.

N-Adamantyl-4-methylthiazol-2-amine suppresses glutamate-induced autophagic cell death via PI3K/Akt/mTOR signaling pathways in cortical neurons

양승주,A Reum Han,최혜림,Kyouk Hwang,Eun-A Kim,최수영,조성우 생화학분자생물학회 2020 BMB Reports Vol.53 No.10

We recently reported that N-adamantyl-4-methylthiazol-2-amine (KHG26693) attenuates glutamate-induced oxidative stress and inflammation in the brain. In this study, we investigated KHG 26693 as a therapeutic agent against glutamate-induced autophagic death of cortical neurons. Treatment with KHG26693 alone did not affect the viability of cultured cortical neurons but was protective against glutamate-induced cytotoxicity in a concentration-dependent manner. KHG26693 attenuated the glutamate-induced increase in protein levels of LC3, beclin-1, and p62. Whereas glutamate decreased the phosphorylation of PI3K, Akt, and mTOR, these levels were restored by treatment with KHG26693. These results suggest that KHG26693 inhibits glutamate-induced autophagy by regulating PI3K/Akt/mTOR signaling. Finally, KHG26693 treatment also attenuated glutamateinduced increases in reactive oxygen species, glutathione, glutathione peroxidase, and superoxide dismutase levels in cortical neurons, indicating that KHG26693 also protects cortical neurons against glutamate-induced autophagy by regulating the reactive oxygen species scavenging system.

In order to examine the value of citrus byproducts as livestock feed, 4 types of CBS were made: T1; wet CMS with high moisture. T?; pre-wilted CMS with low moisture. T3; wet CPS with high moisture. T4; pre-wilted CPS with low moisture. Digestion trials were carried with 3 sheep equipped with rumen fistulars. Rumen liquor pH and total VFA were investigated during the trial period. The daily intake of the trial feed (CBS+hay) was 0.76-0.78㎏ DM (1.8-1.9% by body wt.). Feeding CBS showed the effect of increasing the feed. intake. Compared with high moisture CBS, low moisture CBS increased feed intake and digestibility, and was weak in the tendency of lowering rumen liquor pH. Compared with CPS, CMS showed a tendency more similar to low moisture CBS. Feeding CBS had the effect of increasing urine excretion, water intake and digestibility of DM and DNFE. When fed CBS the pH and total VFA in rumen liquor were lower than when fed hay. Such tendency was shown in the case of feeding high moisture CBS compared to low moisture CBS. The digestibility of CBS had no relationship with pH, but there was a statistical significant correlation between total VFA in rumen liquor and digestibility of CBS. It appears from the results of these trials in the making and utilization of CBS that CMS was better in all respects than CPS and prewilted CBS with low moisture (about 76%) was more effective than wet CBS with high moisture (about 83%).

To utilize citrus byproducts for animal feeds two different silages were made 1) using citrus peel 2) using citrus pulp mixture. The experimental design included 12 treatments, six for citrus peel silage and six for citrus pulp mixture silage, then treatments were allocated according to sun-drying and urea, barley straw and NaOH treated straw additions. Chemical composition, pH, organic acid and NBDMD were examined and treatments compared. Sun-drying (3 days) citrus waste reduced the moisture content by 6-10%. Addition of barley straw reduced the moisture content of the two silages by 4-8%. The content of protein was increased 1.25-1.63% by the urea addition of 0.6% of the silage weight. Crude fiber was increased 4-5% by the addition of 8-10% barley straw, and also increased 7-8% by the addition of 16-21% barley straw. But the change in the other ingredients by the addition of barley straw was not found, except NFE wait decreased. The pH of the non-treated silage was 3.4-4.7, and that was increased by the addition of urea and NaOH. The content of organic acid was changed by the addition of urea as follows: (1) the content of lactic acid was lowered, and (2) L.A./T.A. was decreased. But by the addition of 8-10% barley straw by the silage weight, the content or lactic acid was increased and the standard of L.A./T.A. was heightened. On the contrary, it showed the tendency of decreasing in the case of the addition of 16-20% barley straw. The range of NBDMD of raw citrus byproducts was 79.64-81.11%. That of the citrus byproducts silage was increased by the addition of urea (84.16-88.08%), and decreased by the addition of barley straw (62.4-73.16%). The addition of urea and alkali treated straw significantly increased digestibility especially in pulp mixture silage but had the reverse effect on silage quality.

Although much of the leadership research has focused on constructive leader behaviors, recently researchers has shown their interests in dysfunctional or destructive leader behaviors that can be referred as abusive supervision. Abusive supervision, defined as “subordinates’ perceptions of the extent to which their supervisors engage in the sustained display of hostile verbal and nonverbal behaviors, excluding physical contact”, is one of the most common types of dysfunctional leadership. Previous studies have found that abusive supervision correlates negatively with subordinates’ job and life satisfaction, task performance, and OCB. But, knowledge sharing, defined as individual behaviors that involve sharing task-related ideas, information, and suggestions with others at workplace including coworkers and supervisors, is the fundamental means for accomplishing organizational effectiveness, there is a paucity of studies examining how abusive supervision may become a barrier of individuals’ knowledge sharing. So, in this study, we examine abusive supervision as a barrier to knowledge sharing, both because of this close relationship with discretionary behaviors and the destructive outcomes that occur when employees perceive they are receiving abusive treatment from their supervisors. Furthermore, our study examine this relationship drawing on insights from Psychological Reactance Theory. Psychological Reactance Theory contends that any persuasive message may arouse a motivation to reject the advocacy and when ones freedom is lost he or she may engage in a variety of behaviors in order to regain or prevent the loss of freedom. Abused subordinates often experience frustration along with a diminished sense of personal control, and one way they can restore this sense of autonomy and freedom is by intentionally withholding discretionary behaviors like knowledge sharing. And in order to clarify and investigate the mechanisms between these relationships, we consider the Mediating role of Leader Endorsement and Moderating effect of Self-Efficacy. Out of the process, we developed and empirically tested the following hypotheses: H 1: Abusive supervision is negatively related to knowledge sharing. H 2: Leader endorsement mediates the relationship between abusive supervision and knowledge sharing. H 3: Self-Efficacy moderates the negative relationship between abusive supervision and leader endorsement, such that the negative relationship will be stronger when self-efficacy is high than when it is low. H 4: Self-Efficacy moderates the indirect relationship between abusive supervision and knowledge sharing, such that the negative relationship becomes stronger when self-efficacy is high than when it is low. Data was collected by giving questionnaire to 360 pairs of a supervisor and his/her immediate employee. 300 questionnaires were collected. Among those, 255 dyadic data were used for analysis. The result of this study showed that abusive supervision was significantly and negatively related to employee’s job performance, suggesting the support of Hypothesis 1. Also, to test our hypotheses regarding the mediating role of leader endorsement, the result of mediation analysis suggested the support of Hypothesis 2. And there was a significant interaction effect of Self-Efficacy in the relationship between abusive supervision and leader endorsement, so Hypothesis 3 was supported. Finally, our hypotheses regarding the moderated mediating effect of self-efficacy was supported, suggesting the support of Hypothesis 4. In sum, Hypotheses 1, 2, 3, 4 were supported. This study’s implications, limitations and future research are discussed. 본 연구는 심리적 반발이론을 바탕으로 상사의 비인격적 행동과 구성원의 지식공유간의 관계에서 리더인정의 매개효과와 자기효능감의 조절효과를 검증하였다. 실증분석을 위해 서울 및 충청권 소재 17개 기업에서 근무하는 직원 360쌍을 대상으로 설문조사를 실시하였으며, 수집된 설문 300쌍 중 불성실 및 결측치를 제외한 총 255쌍의 자료가 최종분석에 사용되었다. 실증분석 결과 상사의 비인격적 행동은 구성원의 지식공유에 부(-)적 영향을 미치고, 둘의 관계를 리더인정이 완전매개하는 것으로 나타났다. 또한 자기효능감이 높은 구성원들은 낮은 구성원들에 비해 비인격적 행동을 하는 상사를 리더로 인정하지 않으려는 경향이 강하고, 지식공유 또한 적게 하는 것으로 나타났다. 본 연구는 상사의 비인격적 행동이 구성원의 행동에 미치는 영향에 내재된 메커니즘을 실증적으로 확인했다는 측면과 자기효능감의 조절효과를 검증했다는 측면에서 이론적, 실무적 의미를 지니고 있으며, 연구결과를 토대로 연구의 한계 및 향후 연구방향을 제시하였다.

In the political theater dealing with various treasons against a monarch, the monarchial power has theatrical aspects and so does the theater having political aspects. This superimposed delineation derives from the monarch’s perception about the court and kingship during the Renaissance. James I, as Elizabeth I did, built an image of “player king” in the political realm and made use of the theater to reinforce and stabilize his absolute power. King James used the theater as a way to display his absolute power and at the same time used it as a medium to promote the ideology of his monarchy. In accordance, he made the most use of, one of the most popular forms of drama during the Jacobean era, the masque. In the Tempest, Shakespeare who had never written a masque used the concept of “player king” more ingeniously by making the character Prospero take the role of a monarch, magician, and playwright/director. The purpose of this paper is to investigate how the theatrical aspects of monarchial power and the political aspects of the theater are revealed in the Tempest. A marked example of both the theatrical aspects and political aspects is Prospero’s masque in the Tempest. It does not represent a real masque but a dramatic representation of one in the theater. In doing so it is seen as the combination of art and power, showing that the theater functions as a political weapon for the usurpers of the dukedom, and that the politics celebrates the royal power and glory in a theatrical way. When the theater and the politics in the masque carry on to a point where both of them are inseparable from each other, the absolute power represented becomes fictional construction on the stage in the sense that theater is necessarily illusive. Shakespeare shows the praise of Prospero’s absolute power on the surface, but also reveals the limitation to that power in the background, both of which are also shown by King James, in which Prospero is the symbolic representation of. Such an attitude of Shakespeare does not simply reflects upon the absolute power and monarchy, but helps to shape the politics of the future England that is under transformation from that absolute monarchy.
