We studied the hour-lines of six extant Yangcheon-cheoks in Korea. To find whether Yangcheon-cheok was used in the whole area of Korea, we calculated the length of shadows of Yangcheon-cheok on the Korean Peninsula, Nanjing and Beijing as well as Hanyang (Seoul), according to 24 solar terms. Comparing the length of shadows with hour-lines of those relics, we could find that Yangcheon-cheok was suitable for use at limited times (from 9:00 to 15:00) during the year. Also, this sundial is more appropriate for use at low latitudes than high ones. Among existing relics, that of Seoul Museum of History made with porcelain was much more suitable to use at Hanyang and its higher latitude. Lee's collection was also suitable to use at Nanjing. It is certain that Yangcheon-cheok was a portable sundial which could be used from nine to fifteen of clock all the year around except for the winter season.

Some siphonophores were collected from the Korea Strait, $33^{\circ}59'N-129^{\circ}17'E$ and Yeosu with Issacs-Kidd Midwater trawl net in Sep. 2002. They were identified into Diphyes chamissonis is Huxley, 1859 and Abylopsis eschscholtzi(Huxley, 1859) in the suborder Calycophorae of the order Siphonophora, respectively. They are new to the Korean fauna. As a result of this work, six siphonophores of four families have been reported in Korea.

The solitary wasp genus Phimenes (Hymenoptera: Vespidae: Eumeninae) was reported to occur in Vietnam by , represented by one taxon, Phimenes flavopictus continentalis (Zimmermann), which was synonymized under nominotypical Phimenes flavopictus by . A note on gender of this genus is made in the text. One more species, Phimenes indosinensis is recorded in this study from Dak Lak in the southern and Son La in the northwestern parts of Vietnam for the first time. Detailed descriptions of the female and male of the latter are provided with figures. A key to the two species from Vietnam is also provided.

Caminus jejuensis n. sp was collected from depth of 20 m at Geomeunyeo, Seogwipo, Jejudo Island by a SCUBA diving from April 2004 to December 2008. This new species is similar to C. chinensis from China in the composition of spicules except for the spherasters and they differ in spicule size and growth form. This species has longer orthotriaenes and spherules, smaller sterrasters and oxyasters than those of C. chinensis. This species also has many spherasters in choanosome, but C. chinensis lacks. Morever, the new species is a massive shape with wrinkles, whereas C. chinensis is a club shape with smooth surface. Description and figures of the new species are provided.

A notodontid moth, Disparia diluta (Hampson, 1910) is reported for the first time from the Korean peninsula. At the same time, taxonomical note for D. nihonica (Wileman, 1911) is given. The male genitalia of D. nihonica (Wileman) were erroneously illustrated as those of Neodrymonia delia (Leech) by Tshisjakov and Kwon (1999), and Schintlmeister (2008) cited D. nihonica (Wileman) to be distributed in the Korean peninsula, based on the illustration.

Feeding activites during nestling period of Coal tit (Parus ater) were studied at breeding sites in Mt. Chiri. The average feeding frequency per hour of female Coal tit exceeded that of the male. The average excrement-cleaning frequency per hour of female exceeded that of male, with a longer feed duration. The feeding frequency per hour was generally higher in the morning, and the female exceeded the male in the frquency. It is shown that male of the Coal tit in nestling period played a major role in territorial defense compared with female.

디지털 천체투영기의 보급은 천체투영관의 운영과 교육적 활용 방법에 변화를 가져왔다. 돔영상물 상영이 가능한 디지털 천체투영기를 도입한 천체투영관들의 교육적 활용을 높이기 위해서는 영상물을 활용한 교육 콘텐츠 개발이 선행되어야 하다. 이번 연구에서는 1)AMNH(American Museum of Natural History)에서 사용되고 있는 돔영상물의 교육자 매뉴얼들을 사례조사 하였고, 2)사례조사 결과와 2007 개정 과학과 교육과정을 고려하여 돔영상물 Planets(Astronef Production제작, 2010)의 교육자 매뉴얼을 개발 하였다. 개발된 Planets 교육자 매뉴얼의 활용은 개관 예정인 국립대구과학관과 국립광주과학관 천체투영관의 운영 활성화와 교육활동을 극대화 할 수 있을 것으로 기대된다. 또한 국내에서 수행중인 천문학 프로젝트(KVN, GMT, KMTNet, SKA 등)들의 교육자 매뉴얼 제작에 참고자료로 활용되길 기대한다.

The decapodid stage of Lebbeus comanthi Hayashi and Okuno and the first zoea of Thor amboinensis (De Man) are described based on laboratory-hatched eggs from females collected from Japan. The decapodid stage of L. comanthi is readily distinguished from that of L. groenlandicus by the carapace without anteroventral denticle and tooth behind rostrum, the absence of the antennal spine, the four-segmented outer flagellum of the antennule, the absence of the palp of the mandible, and the telson with posterior margin con caved medially and without dorsolateral spine. The carapace with anteroventral denticle and the third abdominal somite distinctly curved in lateral view distinguish the first zoea of T. amboinensis from that of T. dobkini Chace and T. floridanus Kingsley. Larval characters of the genus Thor are summarized.
