A pagurid crab, Pagurus erythrogrammus is described and illustrated for the first time from Korean waters. It was collected by SCUBA diving in Seogwipo (Jejudo Island) on 30 May 2013. Its morphology is similar to those of known Korean species of the family Paguridae: Boninpagurus pilosipes, Pagurus nigrivittatus, and Pagurus quinquelineatus. This species, however, it is distinguished by having a developed rostrum, seven rows of spines on dorsal surface of the right palm in male, a row of spines on the medial surface of the dactylus of the third pereopod, 12 long ventral spines of dactylus of the third pereopod, six small spines on the concaved distal margin of telson, and three reddish brown lines on lateral surfaces of propodi of the second and third pereopods.

The continuous taxonomic study on decapods from Korean waters revealed that the alpheid shrimps collected from Jejudo Island and Busan were identified as a species belonging to the genus Arete which is an unreported genus from Korean waters. The genus Arete can be distinguished from the most similar genus Athanas by the following. The chelae are broad and oval-shaped in Arete, but in Athanas, the chelae are more or less elongated. The number of carpal segments in the 2nd pereopod is four but five, exceptionally four or six in Athanas. The epipods are present on pereopod 1 and pereopod 2 in Arete, but on pereopod 1-3, exceptionally on pereopod 1 and pereopod 2 or pereopod 1-4 in Athanas. In this paper, Arete dorsalis is reported for the first time from Korean waters. Korean Alpheidae fauna now consists of 27 species of nine genera.

In the present paper a forecasting system of wind power generation for Walryong Site, Jejudo is presented, which has been developed and evaluated as a first step toward establishing Korea Forecasting Model of Wind Power Generation. The forecasting model, KIER forecaster is constructed based on statistical models and is trained with wind speed data observed at Gosan Weather Station nearby Walryong Si to. Due to short period of measurements at Walryong Site for training statistical model, Gosan wind data were substituted and transplanted to Walryong Site by using Measure-Correlate-Predict technique. Three-hour advanced forecast ins shows good agreement with the measurement at Walryong site with the correlation factor 0.88 and MAE(mean absolute error) 15% under.

Two pelagic thaliacean tunicates, Pyrosoma atlanticum and Cyclosalpa quadriluminis, with bioluminescent organ, were collected from Jejudo Island and Korea Strait. In this study, the Pyrosomatida, which is holoplanktonic colonial tunicate with ascidiozooids embedded in a common test, and to which P. atlanticum belongs, is reported for the first time in Korea. The Cyclosalpa in the Salpida has a bar-shaped alimentary canal beside the branchial bar in both oozooids and blastozooids. Cyclosalpa quadriluminis is added to make Cyclosalpa species in Korea from four to five (C. affinis, C. bakeri, C. polae, C. sewelli, and C. quadriluminis). As a result of this study, 27 species of thaliaceans have been reported from Korea.

A newly recorded species, Aora pseudotypica Hirayama, 1984, belonging to the family Aoridae Stebbing, 1899 was collected from Geomundo and Jejudo Islands in South Korea. This species is characterized by having large triangular process on basis of male gnathopod 1. It is morphologically similar to A. typica Krøyer, 1845, but distinguishable by the lack of a large rounded process on the anterior margins of basis and ischium on male gnathopod 1 and having small distal segment on outer ramus of uropod 3. To date, only two genera, Aoroides Walker, 1898 and Grandidierella Coutière, 1904, of the family Aoridae have been recorded in Korea, so this is the first record of the genus Aora from Korea.

An unrecorded species of Oldenlandia brachypoda DC. is newly reported from Seogwipo-si, Jejudo, This species is distinguished from Oldenlandia diffusa, the related taxa by the surface and length of the pedicel, the number of flowerd, the shape of the calyx and capsule. The new Korean name 'je-ju-baeg-un-pul', was given considering the collect locality. The illustration, description and key of characters are provided.

From a result of surveys on the biodiversity monitoring for moths in Korea, six species of micro-moths that were never known from Korea are reported here for the first time from this country. They are: Udea pseudocrocealis(South, 1901) of the family Crambidae, which has been known as endemic to Japan; Epinotia albiguttata (Oku, 1974) of the family Tortricidae, which was known belonging to Hikagehamakia Oku, 1974; and four species of the family Gelechiidae: Protoparachronistis concolor Omelko, 1986 and P. discedens Omelko, 1986, which were described from Primorisk, Russian Far East; Thiotricha pancratiastis Meyrick, 1921, which is known from Isl. Jejudo, and Thiotricha sp. which is being described in a separate paper. Here we provide images of adults and genitalia for the unrecorded species with a brief diagnosis.

The azooxanthellate soft coral Dendronephthya suensoni (Holem, 1895) is distributed mainly around Jejudo Island, Korea. This species was determined as gonochoric with a sex ratio of 2:1 (female:male). Both female and male colonies have one gametogenic cycle a year. The annual reproductive cycle of D. suensoni is dependent on the seawater temperature. In particular, reproduction of the male colony showed a higher positive correlation between seawater temperature and the mean diameter of the spermaries. Gametogenesis in females and males took 6 months and 12 months, respectively. The mean diameter of a mature oocyte was $249.29\;{\pm}\;36.24\;{\mu}m$, with a maximum size of $354.45\;{\mu}m$. Spawning could have occurred in the fall after the seawater temperature began to decrease.

Two new species of the genus Psammocinia (Dictyoceratida, Irciniidae), P. lobatus and P. rubra, are described from Gageodo Island (Sohuksando Island)and Jejudo Island, Korea. Psammocinia lobatus is most closely related to P. wandoensis Sim and Lee in growth form. However, it can be distinguished by its sharp conules and primary and secondary fibres, lightly cored with detritus. Psammocinia rubra is readily distinguished from the other described Psammocinia species by the blunt conules, reddish brown color of specimen, brown color of fibres and filaments, secondary web between adjacent primary fibres and filament coated with brown granules.
