자유제트를 제어하는 방법중 하나는 분사제트 주위에 형성되는 와류를 조절하는 것이다. 이를 위하여 제트노즐 주위에 환형관을 설치하여 환형관으로부터 2차제트를 분사 또는 흡입함으로써 제트주위에 형성되는 전단류를 변화시켰다. 2차제트를 분사하는 경우(R<1.0) 주제트 주위에 형성되는 와류의 발달을 억제함으로써 제트포텐셜코어의 길이가 아주 길어지는 제트유동을 얻을 수 있었고 흡입하는 경우에는(R>1.0) 제트주위의 전단류가 흡입비 R=1.3～l.65에서 대류불안정성에서 절대불안정성으로 바뀜으로써 형성된 와류가 하류에서 제트중심부까지 발전, 결합되는 것을 방지하여 더 긴 포텐셜코어와 중심에서 낮은 난류강도를 얻었다. 위의 결과는 환형관 주위에 부착한 깃의 높이 변화에 따라서 변화하였는데, 이것은 깃이 환형관을 통한 흡입유동의 유로역할을 함으로써 출구 주위의 유체가 직접흡입되는 것을 방지하기 때문이다. 분사제트 벡터링을 위하여 제트노즐 주위의 환형관을 이등분하여 한쪽으로만 흡입함으로써 제트주위에 다른 전단류를 형성함과 동시에 코안다(Goanda)효과를 이용하여 분사제트를 편향시켰다. 편향되는 정도 및 난류성분은 흡입속도비에 따라서 크게 바뀌었다. 실험은 속도분포와 난류강도 측정이 수행되었으며 가시화를 이용하여 유동특성을 관찰하였다.

Seroprevalence of Toxoplasma gondii infection among the residents of Seokmo-do (Island) in Ganghwa-gun, Incheon, Korea was surveyed for 4 years by a rapid diagnostic test (RDT) using recombinant fragment of major surface antigen (SAG1), GST-linker-SAG1A. Sera from 312, 343, 390, and 362 adult residents were collected on a yearly basis from 2010 to 2013, respectively. Total positive seroprevalence regardless of gender was 29.2, 35.3, 38.7, and 45.3% from 2010 to 2013, respectively. Positive seroprevalence in male adults was 43.9, 48.2, 45.4, and 55.3%, which was far higher than that of the corresponding female adults which was 20.7, 29.2, 33.9, and 38.9%, from 2010 to 2013, respectively. This high seroprevalence of toxoplasmosis in Seokmo-do may have been caused in part by peculiar changes in the toxoplasmic environment of the island as it is a relatively isolated area preserving its natural habitat while also being connected by a bridge to the mainland. Further study is necessary to find out symptomatic patients and to confirm the risk factors.

The World exposition is considered as a great event to promote the cultural exchanges of their own urbanism and share the technological developments among the various countries across the all over the world. So many countries in the world desired to host and take part in the EXPO, so far only few countries have had the chance to hold the event and show their uniqueness of urban culture, but we might say the past exhibition as those for display and publication of matters of science, technology and trade, now we must say expositions of the 21th century has come under variations on cultural and informational interchange and humanism from the global issue and problem. What makes possible to maximize the effort of reciprocal communication between people and the public can be the EXPO event as a means of the public information of the theme and this kind of event should suggest the public a message of the topic, message, image and even more the EXPO spirits and theme as an international event gives as much considerably spreading effect as its big scale. In that aspect, the pavilion for the exhibition of EXPO and public information should be recognized as a place for smoothly forming the activities of reciprocal communication between the society and the public, with such a aspect this study, as its purpose of improving as well as communication, concerns the process in projecting the space paradigm of pavilion in the EXPO and public message and information as a means of the communication of the global theme.

Background: Oral health professionals are responsible in Iran for providing a brief tobacco cessation program to smoker patients. The aim of this study was to assess Iranian dental student and dentist practice, knowledge and attitudes toward smoking cessation programs. Materials and Methods: A valid and reliable self-administered questionnaire was designed and distributed to 150 dentists working in Isfahan-Iran and 60 dental students. Some questions were developed based on the expected 5A tobacco cessation protocol. Statements on attitudes focused on professional responsibility towards smoking cessation and its effectiveness. Chi-square, ANOVA, and t test were used for statistical analysis. Results: The cessation program in dental settings covers a small group of patients (18%). Some 69.1% (n=96) of dentists reported asking their patients about tobacco use, 64% (n=83) advising their patients to quit, 33.8% (n=47) assessing their patients willingness to quit and 20% (n=28) reported helping their patients in changing their behavior. A far lower percentage reported active involvement in arranging assistance for smokers to quit (4.3%, n=5). Some 22% of students and 26% of dentists disagreed that the tobacco cessation programs should be as part of dentists' professional responsibility and 70% of them were willing to follow the protocol of tobacco cessation for patients. Conclusions: Iranian dentist performance regarding tobacco cessation is weak. Dentists and students indicated their lack of knowledge as the major reason for non-adherence to the protocol. Therefore, planning to encourage dentist to follow the protocol needs continuous educational programs.

UWISH2 (UKIRT Widefield Infrared Survey for $H_2$) is an unbiased, narrow-band imaging survey of the Galactic plane in the $H_2$ 1-0 S(1) emission line at $2.122{\mu}m$ using the Wide-Field Camera (WFCAM) at the United Kingdom Infrared Telescope (UKIRT). The survey covers about 150 square degrees of the first Galactic quadrant ($10^{\circ}$ < l < $65^{\circ}$; $-1.3^{\circ}$ < b < $+1.3^{\circ}$). The images have a $5{\sigma}$ detection limit of point sources of K~18 mag and the surface brightness limit is $10^{-19}\;W\;m^{-2}$ $arcsec^{-2}$. The survey operation began on 28 July 2009 and has completed on 17 August 2011. We have been studying the supernova remnants (SNRs) in the UWISH2 survey area. Among the known 274 Galactic SNRs, the survey area includes 65 SNRs or 24 percent of the known SNRs. The wide-field and high-quality UWISH2 images allow us to identify both the diffuse extended and compact $H_2$ emission associated with SNRs, which is useful for understanding their physical environment and evolution. The continuum is subtracted from the narrow-band $H_2$ images using the K-band continuum images obtained as part of the UKIDSS GPS (UKIRT Infrared Deep Sky Survey of the Galactic Plane). So far, we have inspected 42 SNRs, and found distinct H2 emission in 14 SNRs. The detection rate is 33%. Some of the SNRs show bright, complex, and interesting structures that have never been reported in previous studies. In this report, we present our identification scheme and preliminary results.

Purpose. : The present study is an attempt to find out the impact of self-citations on Impact Factor (IF) across disciplines. The study examines the number of research articles published across 27 major subject fields covered by SCImago, encompassing as many as 310 sub-disciplines. The study evaluates aspects like percentage of self-citations across each discipline, leading self-citing countries and continents, and the impact of self-citation on their IF. Scope. : The study is global in nature, as it evaluates the trend of self-citation and its impact on IF of all the major subject disciplines of the world, along with countries and continents. IF has been calculated for the year 2012 by analyzing the articles published during the years 2010 and 2011. Methodology/Approach. : The study is empirical in nature; as such, statistical and mathematical tools and techniques have been employed to work out the distribution across disciplines. The evaluation has been purely under-taken on the secondary data, retrieved from SCImago Journal and Country Ranking. Findings. : Self-citations play a very significant part in inflating IF. All the subject fields under study are influenced by the practice of self-citation, ranging from 33.14% to 52.38%. Compared to the social sciences and the humanities, subject fields falling under the purview of pure and applied sciences have a higher number of self-citations, but a far lesser percentage than the social sciences and humanities. Upon excluding self-citations, a substantial amount of change was observed in the IF of subject fields under study, as 18 (66.66%) out of 27 subjects fields faced shuffle in their rankings. Variation in rankings based on IF with and without self-citation was observed at subject level, country level, and continental level.

본 논문은 일제강점기 권번 예기로 활동했던 김정연의 삶을 확인하고 그가 근현대시기를 거쳐 어떤 춤 활동을 했는지, 또 그가 저술한 "한국무용도감" 속의 춤 작품들이 어떤 무용사적 의의를 지니는지를 고찰한 연구다. 서도소리 중요무형문화재 보유자였던 김정연은 문화재 지정 이후 국악계에 전념하면서 무용계에서 낯선 인물이 되었지만, 권번에서는 명무가인 이장산에게 춤을 사사했고 해방 후 1960년대 초까지 춤 활동에 주력했던 것으로 나타난다. 이러한 학습과 창작 활동의 결실인 작품들은 그의 저서 "한국무용도감"에 실렸는데, 본 연구에서는 그간 무용계에서 주목받지 못했으나 근현대 무용사에 있어 활발한 활동을 하고 중요한 업적을 남긴 김정연과 그의 작품을 연구하여 근현대무용사에 있어 어떤 의의를 가지는지 살펴보고자 했다.

시중에 유통되는 과자류 3,716건에 대해 각각의 규격검사를 실시하였으며 그중 36건이 부적합하였다. 부적내역을 보면 빵류가 2건, 건과류가 33건, 사탕류가 1건이먼으며 가장 부적이 많은 건과류는 33건의 부적합 중에서 32건이 유처리 스낵이었다. 유처리 스낵 중 전통한과가 전체 한과의 $8.9\%$에 해당하는 부적률을 보였으며, 부적항목이 튀김유의 산패와 관련된 산가와 과산화물가이어서 유처리 제품의 철저한 위생관리가 이루어져야 할 것이다. 빵류의 영양성분 표시사항은 표시제품 20건 중 18건이 부적절한 것으로 나타나 심각한 수준인 것으로 측정되었다. 빵류에는 영양성분을 반드시 표시하게 되어있으나 표시되지 않은 제품들이 시중에 많이 유통되고 있어 이에 대한 규제가 강화되어야 할 것이다. 결과적으로 과자류 중에서 변질되기 쉬운 유처리 스낵의 철저한 품질관리와 지속적인 주의가 절실히 필요하며, 영양성분 표시에 대한 집중적인 점검과 관리가 요구된다.
