While general belief is that the military alliances are stable and rigid, the authors argue that the states are far more flexible in their behavior and often act against their alliances. This paper looks at states' behavior in the UN GA and looks how it is reflected in participation in military alliances during three periods of history since 1976 to this day. The authors illustrate the need to consider the network representation of co-sponsoring groups in General Assembly votes. They find significant support for their argument, indicating that social aspects can be extended beyond alliances. An application of social network analysis shows some unexpected affiliations in UN GA. If the UN GA is the "true" nature of these countries' alliance strategies, then it might suggest some significant defections and interesting association.

염산 또는 수산화나트륨 수용액의 농도, 온도, 시간 등 처리조건에 따른 작잠견사의 가수분해율을 측정하였으며 산처리 작잠분말과 알칼리처리 작잠분말의 형태 및 구조특성을 주사전자현미경, 적외선 분광분석, X-선 회절분석 등의 방법으로 분석한 결과 다음과 같은 결과를 얻었다. 1. 작잠견사에 대한 염산 및 수산화나트륨의 처리농도와 온도가 높을수록 또한 처리시간이 길어질수록 작잠견사의 가수분해율은 증가하는 경향을 나타내었으나 고온, 고농도의 조건하에서 수산화나트륨을 작잠견사에 처리하는 경우 작잠견사의 가수분해율이 오히려 떨어지는 경향을 보였다. 2. 산 및 알칼리 처리에 의하여 제조된 작잠분말의 형태는 용해도가 30 wt% 부근에서는 섬유상의 형태를 유지하였으며 산처리 분말의 경우 용해도가 증가함에 따라 섬유축 방향으로 조각난 미세한 입자형태를 나타내었으나 알칼리처리 분말의 경우에는 부정형의 입자형태를 나타내었다. 3. 적외선 분광분석 결과 작잠분말은 처리조건과 무관하게 ${\beta}$-sheet 구조의 특성을 반영하는 1635, 1532, 1226, 960, 700 cm$^{-1}$ 흡수대와 ${\alpha}$-helix 구조의 특성을 반영하는 616 cm$^{-1}$ 흡수대가 뚜렷하게 나타나 작잠분말의 주요 conformation은 ${\beta}$-sheet 구조와 ${\alpha}$-helix 구조임을 확인하였다. 4. X-선 회절분석 결과 가수분해율이 낮을 경우 (35 wt%)에는 ${\beta}$-sheet 구조와 ${\alpha}$-helix 구조에 기인하는 회절 피크가 뚜렷하게 나타났으나 가수분해율이 80 wt% 이상으로 증가하면 2${\theta}$=17.1$^{\circ}$ 및 20.0$^{\circ}$의 회절피크만 강하게 나타났다.

A ban on political podcasting during the General Elections 2006 in Singapore was justified by the Singaporean government on the grounds that the new medium had a greater power to influence voters than traditional modes of political discourse. A between-subjects controlled experiment was conducted to test whether podcasts of political speeches had a greater power to influence voters' evaluations of political candidates and likelihood of voting for them than online text-based transcripts of the same speeches. The study also examined whether mere exposure to political speeches online, irrespective of the modality, had an effect on voters' more general political preferences, i.e. the likelihood of support and voting for the opposition. The findings suggest that political podcasts were no more persuasive than text-based websites and that the effects on political preferences, if any, were likely due the exposure to political content online, not because of the nature of the medium. The implications of the findings are discussed.

There is great confusion over what constitutes public diplomacy (PD), who its actors are, and the relevance of non-state actors. In the Korean context, in addition to the general fuzziness of the concept, linguistic peculiarities of the terms gonggong and gongjung both of which refer to public, waegyo, which is interchangeably used for international affairs, foreign policy and diplomacy, and juche which is simultaneously used for actor and agent, add more layers of confusion. While the term PD in Korea is based almost entirely on Western conceptualization, these linguistic peculiarities prevent fruitful conversations among scholars and practitioners on PD. Against this background, this research note explores and addresses conceptual ambiguities that pertains to PD and the policy discourse on the topic, particularly on non-state PD in Korea. The paper draws on Korean government's PD-related policy documents and Diplomatic White Papers and all relevant academic articles found in Korean-language journals registered in the Korean Citation Index (KCI), which are analysed to gain an understanding of the PD-related policy discourse in Korea.

This study describes the geometric characteristic and the 5-axis machining method of end mill body with insert tip. The geometry of end mill body is consisted of the flute part and the insert tip part. Thus, this study defines the flute part as ruled surface with constant helix angle and the insert tip part as rectangular plane on general direction. The geometric algorithm and the 5-axis NC part program were calculated by our programmed software and a sampled end mill body was machined on 5-axis machining center equipped with two index tables. The machined end mill body with insert tip was very agreeable to the designed end mill body with insert tip. Thus, the method proposed in this study may be very useful for the machining of end mill body with insert tip.

The popularity of the Internet has affected international politics in many ways; however, it is seemingly overlooked by most scholars, and in particular, realists who view the Internet as low-politics. This article argues that the impact of the Internet on international politics should not be underestimated. By focusing on the capabilities of the Internet in general and P2P networks in particular, this paper shows how the Internet is able to disseminate soft power resources. This is demonstrated by an examination of the dissemination of Japanese soft power resources through BitTorrent. Finally, it is concluded that the Internet is a plausible agent for distributing the resources of soft power; however, once disseminated, soft power resources do not always transform into soft power. In the end, contextual conditions within states always apply.

This paper examines communication patterns of key Twitter users by considering the socially and politically controversial Sejong City issue in South Korea. The network and message data were drawn from twtkr.com. Social network-based indicators and visualization methods were used to analyze political discourse among key Twitter users over time and illustrate various types of Tweets by these users and the interconnection between these key users. In addition, the study examines general Twitter users' participation in the discussion on the issue. The results indicate that some Twitter profiles of media outlets tend to be very dominant in terms of their message output, whereas their Tweets are not likely to be circulated by other users. Noteworthy is that Twitter profiles of individuals who are geographically affiliated with the issue are likely to play an important role in the flow of communication.

This case study takes a look at the hyperlink networks extracted from the websites of 367 international non-governmental organizations (NGOs) with datasets from 2010, 2012 and 2014. The first level of evaluation focuses on connections between the NGOs, identifying important nodes, groups and their relations. The second level takes into account the broad range of networked websites from the World Wide Web delivering insights into general networking patterns. The third level explores the underlying spatial configurations of the network which offers a great variety of geographic insights on information flows between and within continents, countries and cities. The most interesting findings of this study are a low level of interconnectedness between the NGOs and at the same time a strong spatial concentration of all embedded network actors.

The purpose of the study was to find out which posts were answered in a text-based computer-mediated social support group. Specifically, the present study examined the effects of two variables on support-seeking behaviors: support-seeking strategies and gender. A revised typology of support-seeking strategies originally proposed in the Sensitive Interaction Systems Theory (SIST) model was employed for the study. Data were collected from the PTT psychosis discussion group, the largest BBS in the Chinese-speaking community, for a period of 30 months from February 2004 to July 2006. In general, the results indicated that posts with more asking, less crying and less hinting were answered more than posts with more hinting, more crying and less asking. However, although different support-seeking strategies did affect support-seeking behaviors, gender did not have an impact on which posts were answered.

Alternate members of the Chinese Communist Central Committee are often overlooked regarding elite formation or even when assessing Chinese elites in general. This article focuses on the case of alternate members of the Central Committee from 1992 to 2007 in order to understand why some individuals will eventually be promoted and why some will never be. Through extensive quantitative testing, I argue that these non-promoted individuals differ from their counterparts in many ways, most of which can possibly be traced back to the type of formation they received early on. As such, the article concludes that Party School attendance and the age factor, through threshold analysis, are a significant factor helping us understand the difference between promoted and non-promoted houbu.
