No full textInterface-Engineered Charge-Transport Properties in Benzenedithiol Molecular Electronic Junctions via Chemically p-Doped Graphene Electrodes
No full textIn this study, we fabricated and characterized vertical molecular junctions consisting of self-assembled monolayers of benzenedithiol (BDT) with a p-doped multilayer graphene electrode. The p-type doping of a graphene film was performed by treating pristine graphene (work function of similar to 4.40 eV) with trifluoromethanesulfonic (TFMS) acid, producing a significantly increased work function (similar to 5.23 eV). The p-doped graphene-electrode molecular junctions statistically showed an order of magnitude higher current density and a lower charge injection barrier height than those of the pristine graphene-electrode molecular junctions, as a result of interface engineering. This enhancement is due to the increased work function of the TFMS-treated p-doped graphene electrode in the highest occupied molecular orbital-mediated tunneling molecular junctions. The validity of these results was proven by a theoretical analysis based on a coherent transport model that considers asymmetric couplings at the electrode-molecule interfaces.111sciescopu
One Place After Another : Site-Specific Art and Locational Identity
No full textKwon traces the development of site-specific art from the 1960s to the 1990s, examining site-specificity as a locus of the dynamic relationship between place and identity in late capitalism. The author distinguishes the more recent work from the earlier by highlighting how it points to the exhaustion of the rhetoric of political progressivism inherent in the practice. Characterising community as an inoperative spectre, Kwon calls for new models of belonging. Index. Circa 300 bibl. ref
Move over Marcus Welby, M.D. and Make Way for Managed Care: The Implications of Capitation, Gag Clauses, and Economic Credentialing
No full textThe author examines the transformative impact of managed care on the medical profession and patient-provider relationships. The article highlights the implications of capitation, gag clauses, and economic credentialing in shaping healthcare delivery and physician autonomy. Kwon argues that these practices can undermine the quality of care and patient trust, as financial incentives often prioritize cost savings over patient welfare. Through a critical analysis, the author calls for reforms to address the ethical challenges posed by managed care systems. Ultimately, the piece advocates for a healthcare model that balances economic efficiency with the fundamental principles of patient-centered care
Unilateral partial nephrectomy with warm ischemia results in acute Hypoxia inducible factor 1-alpha (HIF-1α) and toll-like receptor 4 (TLR4) overexpression in a porcine model
No full textPurpose: Ischemia/reperfusion (I/R) during partial nephrectomy (PN) contributes to acute kidney injury (AKI), which is inaccurately assessed using existent clinical markers of renal function. We evaluated I/R-related changes in expression in hypoxia inducible factor 1α (HIF-1α) and toll-like receptor 4 (TLR4), within kidney tissue and peripheral blood leukocytes (PBL) in a porcine model of PN.
Materials and Methods: Three adult pigs each underwent unilateral renal hilar cross clamping for 180 min followed by a 15 min reperfusion. The contralateral kidney served as control. Biopsies of clamped kidneys were obtained at baseline (time 0), every 60 min during the hypoxic phase, and post-reperfusion. Control kidneys were biopsied once at 180 min. Peripheral blood was sampled at time 0, every 30 min during the hypoxic phase, and post-reperfusion. HIF-1α and TLR4 expression in kidney tissue and PBL were analyzed by Western blotting. I/R-related histological changes were assessed.
Results: Expression of HIF-1α in clamped kidneys and PBL was below detection level at baseline, rising to detectable levels after 60 min of hypoxia, and continuing to rise throughout the hypoxic and reperfusion phases. Expression of TLR-4 in clamped kidneys followed a similar trend with initial detection after 30–60 min of hypoxia. Control kidneys exhibited no change in HIF-1α or TLR-4 expression. I/R-related histologic changes were minimal, primarily mild tubular dilatation.
Conclusions: In a porcine model of PN, HIF-1α and TLR4 exhibited robust, I/R-related increases in expression in kidney tissue and PBL. Further studies investigating these molecules as potential markers of AKI are warranted.Peer reviewe
Generalization of spontaneous imitation from nonwords to real words
No full textThis study reports that English speakers, after shadowing English-like nonwords beginning on /p/ with extended voice onset time, spontaneously shifted their subsequent reading productions of English words converging toward the shadowing targets. The extent of the imitative changes correlated positively with the speakers' declarative memory of the nonwords, but not with the lexical frequency of the produced words. These findings provide evidence for the phoneme-level abstraction in perceptually induced phonetic drifts while they further suggest that the mechanisms underlying phonetic drifts in direct shadowing, and in subsequent productions of words differing from the shadowing targets, may not be identical.

A Study on Motherhood in Jeongsaeng Kwon's Juvenile Stories
No full textFocusing on the 'motherhood' in Jeongsaeng Kwon's juvenile stories, this thesis investigates the author's orientation and perception of the world in which motherhood helps to overcome wars or some crises of a similar kind, to tolerate, consider and rescue other beings, and to better harsh and tragic circumstances. The existing studies have committed a fault in that they claim that Kwon's stories reinforce the ideology of motherhood. They have simply applied to Kwon's works the existing analysis for male authors' writings in terms of feminism. This thesis points out that despite being a male writer, Kwon criticizes males' violence and authority, and takes an affirmative stance toward women and mothers who have been scapegoats for the history. In addition, Kwon describes various characters, irrespective of sex or age, as maternal, which shows that the motherhood he aims at is not confined to a biological sex.
Chapter Ⅱ examines Kwon's preschool children's Ⅱ stories. Most of these stories, except a few, have children in the center. The children serve as a motherly being who saves other lives or awakes adults from foolishness which is ascribed to stereotypes and corruption. The most maternal character is God, which comes to form a hierarchical structure of space. This structure, however, is being destructed as the God's creatures and belongings come down to the ground.
Chapter Ⅲ looks into Kwon's schoolchildren's Ⅲ stories. Kwon shows both kinds of parents and adult generations, those with motherhood and those without motherhood. However, most of his works underscore the motherhood in parents and adults who teach and enlighten children. In the case of parentless children, children themselves, grandparents, or other adults act as motherly characters. God, who is the most maternal, comes incarnated to the ground, which leads to the circular structure of space. However, the ground space is demolished for varied reasons, and the meaning of space remains tragical till the end of a story.
Teenage novels investigated in chapter Ⅳ can be characterized by orphanhoods owing to the war. The children, who were deprived of parents, become motherly beings and try to take care of others and revive others' lives. These children themselves can get over the extreme situation of the war, thanks to maternal adults' care and help. The spaces like a house, village, and nation, which are likened to woman and motherhood in Kwon's teenage novels, are destroyed, and the characters do not stay in a place but roam and wander about places. However, the spaces turn into motherhood, due to the characters who try to look after and rescue each other. On the other hand, Kwon's teenage novels present God as the absolute being, and criticize the wrongdoing of churches and believers in the concrete.
To recapitulate, Jeongsaeng Kwon aims at the motherhood that can provide straightforward teachings, rescue and protect others' lives,consider other people, and live and let live. In order to illuminate children on this theme, the author presents multifarious characters of motherhood, via different personae and spaces in many of his stories. Through these characters, children can experience and learn motherhood, directly or indirectly.
Although the juvenile literature is closely related to motherhood, there have not been many in-depth studies on motherhood in juvenile stories, thus far. Kwon's stories show the motherhood which confronts and tries to overcome wars, crises, and hardships. This may be the sublime virtue that should be realized and learned by the children and adult generations who live in the present.;본고는 권정생의 아동소설에 나타나는 ‘모성성’을 고찰해 봄으로써 권정생 아동문학에 나타나는 모성성이 전쟁, 혹은 그와 비슷한 위기를 견뎌내게 하고, 다른 존재를 포용하고 배려하며 살리고, 힘들고 비극적인 환경을 풍요롭게 하고자 하는 작가의 지향점과 세계 인식을 드러내는 것이라고 보고 이에 대해서 살펴보고자 하였다. 그리고 본고는 권정생의 아동문학이 모성이데올로기를 강화하고 있다고 보는 기존연구는 남성작가들의 작품을 페미니즘적으로 분석한 결과를 권정생의 작품에도 그대로 적용한 데서 발생한 오류를 범하고 있으며, 권정생은 남성작가이지만 남성의 폭력성과 권위적인 모습을 비판하며, 여성과 어머니들이 역사의 희생양이 되어 온 것에 주목해 그들에게 긍정적인 시선을 보내고 있다는 점을 지적하였다. 그리고 권정생은 남녀노소에 상관없는 다양한 인물들을 모성적인 인물로 그리고 있으며, 이로써 권정생이 지향하는 모성성은 육제적인 성(性)에 국한되지 않는다는 것을 알 수 있었다.
Ⅱ장에서는 권정생의 유년동화를 살펴보았는데, 권정생의 유년동화는 소수의 몇 편을 제외하면 아동이 중심인물로 등장한다. 이러한 아동은 다른 생명을 살리고, 고정관념에 젖어있거나 부정부패한 어른의 어리석음을 깨우치는 모성적인 존재였다. 가장 모성적인 인물은 하나님인데, 이로 인해 권정생 유년동화의 공간은 위계적인 공간 구조를 형성하고, 하나님의 피조물과 부속물이 땅 아래로 내려오면서 위계적인 공간 구조를 벗어나고자 하는 시도가 이루어졌다.
Ⅲ장에서는 권정생의 일반동화를 살펴보았다. 권정생의 일반동화는 모성적인 부모, 기성세대와 비모성적인 부모, 기성세대의 모습을 모두 보여주지만 다수의 작품에서 모성적인 부모와 기성세대의 모습을 그림으로써, 아동을 깨우치고 교육시키는 기성세대의 모습이 강조되었다. 부모가 없는 아동의 경우 아동 자신, 조부모, 주위의 어른들이 모성적 인물이었고, 가장 모성적인 하나님은 육화(肉化)되어 지상으로 내려오고, 이로 인해 순환적인 공간 구조가 형성되었다. 그러나 지상의 공간은 여러 요인으로 인해 파괴되고, 그 공간의 의미는 작품의 말미까지 비극적으로 머물렀다.
Ⅳ장에서는 권정생의 소년소설을 살펴보았다. 권정생의 소년소설은 전쟁 전후를 배경으로 하는 작품이 많아, 부재하는 부모의 모습을 많이 보였으며, 부모의 부재를 경험한 아동은 그들 스스로 모성적 인물이 되어 다른 이들을 보살피고 다른 이의 생명을 살리려고 하였다. 그리고 아동은 모성적인 어른들의 보살핌과 도움으로 전쟁이라는 극한 상황을 이겨낼 수 있었다. 권정생의 소년소설은 집, 마을, 국가 등 여성과 모성으로 비유되는 공간들이 파괴되어 등장인물이 한 공간에 머물지 못하고 유랑하고 방황하는 모습을 보인다. 그러나 권정생 소년소설의 공간은 서로 보살피고 살리려고 하는 등장인물로 인해 모성적인 공간으로 변모한다. 그리고 권정생의 소년소설은 절대자로서의 하나님의 모습을 그리면서 잘못된 교회와 교인들을 구체적으로 비판하고 있다.
이로서 본 논문은 권정생이 올바른 가르침을 전하고, 타인의 목숨을 살리고 보호하며, 남을 배려하고 모든 생명체가 상생할 수 있는 모성성의 세계를 지향하고 있으며, 작가는 이러한 주제를 아동에게 전하고자 다수의 작품에서 인물과 공간을 뛰어넘는 다채로운 모성적인 인물을 그리고 있다. 아동은 이러한 인물들의 모습을 보면서 직, 간접적으로 모성적인 인물에 대해서 느끼고, 배울 수 있게 된다.
아동문학은 모성과 밀접한 관련이 있음에도 불구하고 그동안 아동문학에 나타나는 모성성을 깊이 있게 연구한 자료는 많지 않다. 그러나 권정생의 아동문학은 전쟁과 위기, 고난의 순간을 다루면서 그런 상황을 극복하고자 하는 모성성을 드러내고 있으며, 이는 현재를 살아가야 할 아동과 기성세대가 느끼고 배워야할 지고(至高)의 가치일 것이다.Ⅰ. 서론 = 1

Tinggi rendahnya motivasi berprestasi dipengaruhi oleh faktor-faktor motivasi berprestasi yaitu menghendaki umpan balik (feed back), berorientasi pada keberhasilan, tahan terhadap tekanan, integrasi. Keberhasilan untuk mencapai tujuan anggota Tae Kwon Do tidak hanya berjalan dengan mudah tetapi perlu adanya usaha yang keras dalam melatih dan memaksimalkan motivasi berprestasi, selain itu yang perlu diperhatikan yaitu faktor pengambilan keputusan yang mana merupakan proses tindakan untuk memilahkan masalah-masalah yang dihadapi dalam diri individu atau organisasi. Dengan melalui alternatif-altrnatif yang memungkinkan untuk membuat keputusan yang lebih baik. Adapun faktor-faktor dari pengambilan keputusan adalah: keadaan intern, tersedianya informasi, keadaan ekstern dan kepribadian.
Hipotesis yang diajukan dalam penelitian ini adalah adanya hubungan positif antara motivasi berprestasi dengan pengambilan keputusan anggota UKM Tae Kwon Do UIN Maulana Malik Ibrahim Malang, instrumen yang digunakan dipakai dalam mengumpulkan data dalam penelitian ini adalah dengan menggunakan angket. hasil penelitian di dapatkan pada populasi, jenis penelitan ini adalah penelitian sampel kerena subjek lebih dari seratus dan pengambilan subjek penelitian diambil acak sebanyak 30 mahasiswa (20% dari populasi) anggota UKM Tae Kowon Do UIN Maulana Malik Ibrahim Malang.
Penelitian ini menggunakan analisis korelasi prodct moment dari Karl Person. Hasil penelitian menujukkan Bahwa tingkat motivasi berprestasi tinggi 13%, sedang 74%, rendah 13%. Untuk pengambilan keputusan diperoleh prosentase tinggi 20%, sedang 67%, rendah 13%. Korelasi antar variabel adalah rxy = 0,605 yang berarti hipotesa dalam penelitian ini diterima bahwa terdapat hubungan yang positif antara motivasi berprestasi dengan pengambilan keputusan anggota UKM Tae Kowon Do UIN Maulana Malik Ibrahim Malang. Dimana apabila semakin tinggi motivasi berprestasi dalam berlatih Tae Kwon Do maka semakin tinggi pula pengambilan keputusan dalam bertindak anggota UKM Tae Kwon Do UIN Maulana Malik Ibrahim malang.
ABSTRACT
Research aims at understanding the relationship between the motivation for achievement and the decision making of the member of UKM Tae Kwon Do at UIN Maulana Malik Ibrahim Malang.
This becomes interesting for the author because the motivation for achievement underlines the success of UKM Tae Kwon Do. The fluctuation of this achievement seems affected by the factors of the motivation for achievement such as the interest for feedback, the orientation toward success, the resistance against pressure, and the integration. The success of the member of UKM Tae Kwon Do in pursuing the goal not only develops easily but also needs hard work in training and in maximizing the motivation for achievement. The other consideration relates to the factor of decision making in which supposed to be made in sorting the problems dealt by individual or organization. The selection of alternatives facilitates the better decision making. Factors of decision making may include internal condition, information availability, external condition, and personality.
Hypothesis of research proposes the positive relationship between the motivation for achievement and the decision making of the member of UKM Tae Kwon Do at UIN Maulana Malik Ibrahim Malang. The research instrument in collecting the data involves questionnaire. Considering the population, type of research subsumes into sample study because the subject remains over a hundred. The sampling has been conducted randomly resulting in 30 students (20 % the population) as the member of UKM Tae Kwon Do at UIN Maulana Malik Ibrahim Malang.
Research employs Karl Pearson’s correlation product moment analysis. Results of research indicate that the motivation for achievement obtains high, medium and low scores with levels of 13 %, 74 % and 13 %. The decision making shows high, medium and low scores with levels of 20 %, 67 % and 13 %. The correlation between variables will be rxy = 0.605 meaning the hypothesis of research must be accepted that the positive relationship can be developed between the motivation for achievement and the decision making of the member of UKM Tae Kwon Do at UIN Maulana Malik Ibrahim Malang. The higher the motivation for achievement in practicing Tae Kwon Do corresponds with the higher the decision making made by the member of UKM Tae Kwon Do at UIN Maulana Malik Ibrahim Malang to give necessary action
