Behavior of thermal bubbles formed from a single nucleation site
장영수,정광훈,이헌주,이윤표,김호영 대한기계학회 2010 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.24 No.1
Thermal bubble formation is a fundamental process in nucleate boiling heat transfer and in many microelectromechanical thermal systems. Here, we report an experimental study of the dynamic and thermal behavior of bubbles generated at a single site, that is, a microcavity filled with alumina particles. The thermal process associated with the bubble departure from the isolated cavity, in particular, was shown to be different from that of macroscale boiling. The bubble departure diameter remains constant in a low superheat (or Jakob number) regime which is solely determined by the balance of interfacial tension and buoyancy. In addition, the bubble departure frequency increases along the bubble size as the substrate temperature rises. The further-increased frequency of bubbles emerging from the cavity causes multiple bubbles to coalesce before the preceding bubble completely detaches from the substrate, thus, leading to the decrease of apparent departure frequency with the increase of substrate temperature.

The purpose of this study was to examine the cultural diversity in terms of costumes by analyzing the costumes depicted in the early Kushan Dynasty relics, Tillya Tepe. As a research method, literature research and artifact analysis were conducted in parallel. The type of costume worn by the king (or priest) was in the type of a jacket and skirt, which was thought to be of Persian influence. The Greek god of Dionysos was wearing a costume with Danryong(團領) and narrow sleeves, a nomadic type of Central Asia. It could be seen that costumes were transformed into indigenous elements of the region. The shape of the helmet worn by the warrior was a Greek-Macedonian helmet. However, details were transformed into indigenous elements of the Kushan dynasty. The clothing of a nobleman riding a carriage was an element of dress that was observed in Chinese po(袍), and was an unusual element not found in nomadic peoples. There were goddesses wearing Greek robes like Aphrodite in Tillya Tepe's relics. On the other hand, there were goddesses who did not wear Greek chitons like the Greek goddess Athena. Instead, they wore high-waisted robes worn by the Orient goddesses. In addition, after Kushan occupied India, there were Indian elements believed to be expressed by accepting Indian culture. These elements were combined with regional orient elements of the Kushan dynasty, Central Asian elements, and Kushan's own elements. Thus cultural diversity emerged in the costumes depicted in Tillya Tepe artifacts.
스키타이인의 머리형태와 수염에 대한 연구 - 흑해 북쪽지역 스키타이인을 중심으로 -

In ancient times, hairstyle varies according to tribes. Because it is a social product that depends on status, class, and gender within the tribes, research on the hairstyle is an important source for studying the culture of the tribes. The purpose of this study is to analyze hairstyle of the Scythians and to understand the culture of the Scythians. Furthermore, the purpose is to identify the ethnic group based on this research. And it is intended to use the results as a comprehensive resource for research on the origins of Korean ancient costumes. As a research method, literature study and artifact analysis were performed concurrently. Data for artifact analysis were taken directly from the Eremitage Museum in St. Petersburg, Russia, where the researcher visited for this study. The conclusions of this study are as follows: Hairstyle of the Scythians were classified into three types: straight hair, braided hair, and tied hair depending on social status, age, and region. Straight hair was usually seen with kings, royalty, and warriors, and the hair length varied according to their status. Braid hair appears by a depiction of an old man and young Scythians. Tied hair was observed in the warrior. The beard was divided into chin-beard and mustache. Long chin-beards and mustaches were mostly observed in the ruling classes, while medium length chin-beards and short mustaches were considered the most common form of beard because they appeared in most classes. The young Scythians, regardless of their status, had no beard.
사전선거운동 제한은 위헌인가? – 헌재 2022. 02. 24. 2018헌바146 결정에 대한 평석 –
장영수 한국헌법학회 2022 憲法學硏究 Vol.28 No.2
헌재 2022. 02. 24. 2018헌바146 결정은 공직선거법 제59조에 의한 사전선거운동 중에 “개별적으로 대면하여 말로 하는 선거운동에 관한 부분”, 그리고 공직선거법 제254조 제2항의 “그밖의 방법”에 관한 부분에 “개별적으로 대면하여 말로 하는 선거운동에 관한 부분”이 헌법에 위반된다고 결정함으로써 인터넷을 이용한 사전선거운동금지에 대한 위헌결정에 이어 사전선거운동 제한의 범위를 다시 크게 축소시켰다. 결과적으로 사전선거운동 제한은 방송을 통한 선거운동 등의 매우 제한된 범위에서만 존속하며, 사실상 그 존재의미가 크게 약화된 것이다. 이 논문에서는 이 결정이 향후 선거과정에 미칠 파급효를 고려하여 사전선거운동 제한의 문제를 심층적으로 검토하였다. 그 결과 최근 10여년 동안 헌법재판소가 사전선거운동 제한에 대한 예외를 지속적으로 확대하였으며, 사실상 사전선거운동 제한이 대폭 축소되었음을 확인하였다. 그런데 이 결정의 주된 논거가 되고 있는 ‘개별적으로 대면하여 말로 하는 선거운동’에 대한 예외 인정은 사전선거운동 제한을 사실상 유명무실하게 만들 수 있을 정도의 파급효가 있을 뿐만 아니라, 그로 인하여 선거운동의 과열과 혼탁, 심지어 불법과 비리에 대한 우려가 커지고 있다는 점에 주목하였다. 최근 제20대 대통령선거에서 나타나듯이 네거티브 선거운동의 과열, 부정선거 논란 등이 오히려 심해지고 있다는 점을 고려할 때, 헌법재판소 결정을 통한 사전선거운동 제한의 형해화에 대해서는 진지한 반성적 숙고가 필요할 것으로 생각한다.
