Purpose: Early surgical management is the standard of care for penile fracture. Conservative treatment is an option with recent reports revealing lower success rates. We reviewed the data and long-term outcomes of patients with penile injury submitted to surgical or conservative treatment. Materials and Methods: Between January 2004 and February 2012, 42 patients with penile blunt trauma on an erect penis were admitted to our center. We analyzed the following variables: age, etiology, symptoms and signs, diagnostic tests, treatment used, complications and erectile function during the follow-up. One patient was excluded due to missing information. Thirty-five patients underwent surgical repair and 6 patients were submitted to conservative management. Results: Mean follow-up was 19.2 months (range, 7 days to 72 months). The mean elapsed time from trauma to surgery was 21.3±12.5 hours. Trauma during sexual relationship was the main cause (80.9%) of penile fracture. Urethral injury was present in five patients submitted to surgery. Dorsal vein injury occurred in three patients with false penile fracture and concomitant spongious corpus lesion was present in three patients. During follow-up, 31 cases (88.6%) of the surgical group and four cases (66.7%) of the conservative group reported sufficient erections for intercourse, with no voiding dysfunction and no penile curvature. However, the remaining two patients (33.3%) from the conservative group developed erectile dysfunction and three patients (50%) developed penile deviation. Conclusions: Surgical approach provides excellent functional outcomes and lower complications. Early surgical management of penile fracture provides superior results and conservative approach should be avoided.

일본에서 문화연구의 동향과 쟁점

야마 요시유키(山泰幸)(YAMA Yoshiyuki),전성곤(Jun, Sung-Kon)(번역) 한국문화연구학회 2013 문화연구 Vol.2 No.1

본 논고는 일본의 문화연구 동향의 전반적인 개관을 기술하는 것이다. 1990년대 중반 일본에 도입된 ‘컬츄럴 스터디즈’(이하, CS)로 아카데미즘의 제 분야를 월경하는 문화연구가 유행하게 되었다. CS는 에드워드 사이드의 오리엔탈리즘 비판이나 푸코의 권력분석 이론들과 연동하면서 새로운 사상적 조류를 만들어 내고, 학지(學知)와 권력 관계에 대한 자아비판을 요구했다. 연구자들도 포지션 문제가 아주 강도 높게 힐문 당했다. 그러나 일본에서의 CS가 독립된 분야로 확립되지는 못했고, 문학이나 미술사, 영화 연구, 인류학이나 사회학 분야 등등, 기존의 인문사회과학 분야에 속하는 연구자들이 CS연구자라는 실정이다. 일본에서는 ‘문화연구’라고 할 경우 ‘문화사회학’ 혹은‘문화의 사회학’을 연구하는 연구자들이 대부분이다. 그 이유는 일본에서 문화연구가 사회학을 기반으로 발달했기 때문이다. 또한 일본에서의 문화연구 동향에서 중요한 것은 문화인류학이다. 문화인류학이 현지인의 주체성을 중시한다는 의미에서 실시한 문화개념 갱신은 CS와 연결되면서 기존의 인류학이 가진 정치성에 대한 비판과 반성, 발화(発話) 포지션 문제, 타자연구에서 자아연구로 전환하는 계기를 만들었다. 민족문화의 관광자원화나 자문화(自文化) 내부의 에스니스티 마이너리티 표상의 정치역학을 주요 연구테마로 상정하고 있다. 동시에 일본에서 문화연구의 또 하나의 쟁점은 다양성과 획일성 사이의 딜레마다. 다양한 문화형태 출현은 역설적으로 문화형태의 평면화(平面化)를 가져왔다. The aim of this paper is to give a description of the general overview of Japan’s trend of culture study. As the Cultural Studies (hereinafter, ‘CS’) which were introduced into Japan in the mid 1990s, the ones passing through the general fields of academism came into vogue. CS in line with Edward W. Said’s criticism of Orientalism or Michel Foucault’s power analysis theory, etc., created a new ideological tide and demanded the self-criticism about the power relations with Knowledge. Researchers were also under cross-examination about the issue of their position very intensely. However, CS in Japan failed to be established as an independent field and the realities are that the researchers, who belong to the existing humanities and social sciences disciplines, such as literature, art history, film studies, anthropology or sociology, etc., are actually the ones of CS. When it comes to ‘Cultural Studies’ in Japan, its realm is dominated mostly by the researchers on ‘Cultural Sociology’ or ‘Sociology of Culture.’ It’s because the culture studies in Japan have developed on the base of sociology. In addition, what matters in the trend of CS in Japan is cultural anthropology. The renewal of the cultural concept, which was implemented as a meaning that cultural anthropology values independence of locals, created an impetus for the criticism and self-reflection of the politicity of the existing anthropology, an issue of telling position, and conversion from the research on others to the research on self as it was linked to CS. CS is bringing in the issue of turning the national culture into tourist resources, or the dynamics of ethnic minority emblem of the internal own culture as a major subject of study. In addition to this, another controversial issue of CS is a dilemma between diversity and conformity. Paradoxically speaking, the advent of diverse cultural forms has brought the complanation of a cultural form.

Culture, Ambiguity Aversion and Choice in Probability Judgments

The universal cultural validity of the comparative ignorance hypothesis of ambiguity aversion was investigated. We also examined if cultural differences in choice preference were observed between Westerners, by using a sample of French participants, and Easterners by using a sample of Japanese participants. Furthermore, we investigated if differences in choice preference were observed within each cultural group. We conducted two experiments using the Ellsberg’s two-color problem. Results indicated that ambiguity aversion decreased in a non-comparative betting condition (Experiment 2) compared to a comparative betting conditions (Experiment 1), which supported the weak version of the comparative ignorance hypothesis. We also found that personal choice was more important for French than for Japanese participants. However French participants did not put as much weight on personal choice, as did Americans in previous studies.

Postal Addresses As An Assay of Cultural Cognition

The present study investigate/d cultural differences in semantic processing, using a city-to-state and state-to-city priming task, in Japan, Malaysia and the United States. Prior research suggests that Easterners tend to engage in context-dependent cognition whereas Westerners tend to engage in context-independent cognition (Nisbett et al., 2001). According to this view, Japanese and Malaysians should show a greater facilitation effect when state name (context) is presented before city name (object) and/or should be more strongly affected by the prime as a contextual cue. However, if domain-specific knowledge about postal addressing order affects semantic priming, both Malaysians and Americans (who share a city-to-state postal address style) should show greater facilitation from city-to-state priming. The results showed cultural differences in the long SOA (700ms) priming task: Americans and Japanese showed significant differences between congruent pairs (e.g., Texas-Dallas) and incongruent pairs (e.g., Texas-Chicago), both in state- to-city and city-to-state priming, whereas Malaysian didn’t show such differences in state-to-city priming. On the other hand, in the short SOA (200ms) priming task, there were no differences between Easterners and Westerners in amount of priming. These results imply that when the priming order didn’t fit the domain-specific knowledge about addressing order, but was consistent with the culturally engaged cognitive tendency, this domain-general cognitive tendency facilitated the target processing via conscious use of strategies.

<P>Despite possessing substantial regenerative capacity, skeletal muscle can suffer from loss of function due to catastrophic traumatic injury or degenerative disease. In such cases, engineered tissue grafts hold the potential to restore function and improve patient quality of life. Requirements for successful integration of engineered tissue grafts with the host musculature include cell alignment that mimics host tissue architecture and directional functionality, as well as vascularization to ensure tissue survival. Here, we have developed biomimetic nanopatterned poly(lactic-<I>co</I>-glycolic acid) substrates conjugated with sphingosine-1-phosphate (S1P), a potent angiogenic and myogenic factor, to enhance myoblast and endothelial maturation. Primary muscle cells cultured on these functionalized S1P nanopatterned substrates developed a highly aligned and elongated morphology and exhibited higher expression levels of myosin heavy chain, in addition to genes characteristic of mature skeletal muscle. We also found that S1P enhanced angiogenic potential in these cultures, as evidenced by elevated expression of endothelial-related genes. Computational analyses of live-cell videos showed a significantly improved functionality of tissues cultured on S1P-functionalized nanopatterns as indicated by greater myotube contraction displacements and velocities. In summary, our study demonstrates that biomimetic nanotopography and S1P can be combined to synergistically regulate the maturation and vascularization of engineered skeletal muscles.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2017/ancac3.2017.11.issue-12/acsnano.7b00186/production/images/medium/nn-2017-001868_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn7b00186'>ACS Electronic Supporting Info</A></P>
