Four species of the genus Exochus belonging to the subfamily Metopiinae, family Ichneumonidae, are reported in South Korea for the first time. The subfamily Metopiinae was recorded by Förster in 1869 based on genus Metopius and more than 870 described species have been reported worldwide. Among the genera of Metopiinae, genus Exochus is the largest, which is cosmopolitan and comprises more than 290 described species worldwide (Choi et al., 2016; Yu et al., 2016). A taxonomic study of South Korean Exochus was initiated by Choi et al. (2014), who reported four species. Until now, 10 species have been described as new species and 25 species were recorded as new records of this genus from South Korea (Choi et al., 2014, 2016). In the present study, the following four species are reported in South Korea: Exochus latiareolus Tolkanitz, 2003, E. ornatus Momoi & Kusigemati, 1970, E. pictus Holmgren, 1858, and E. yasumatsui Momoi, Kusigemati & Nakanishi, 1968. In addition, we provide the diagnoses of these four species along with diagnostic photographs.

This study tries to evaluate the effect of ITT introduction in Busan New Port. The study used the estimation model of the number of vehicles required in accordance with the backhaul rate. The model used big data, COPINO e-document for one year in 2015. COPINO recorded the event such as truck ID, container ID, ATA, damage etc when truck arrived at gate. The study finds important information to estimate the required number of trucks for handling current ITT containers in Busan New Port: Daily throughput in Busan New Port is 1650 vans, especially night throughput recorded peak level in 1800 hours to 2400 hours, the throughput between adjacent terminals recorded high, i.e PNIT to HPNT. The transportation capability for 6 hours between terminals is from 4 vans to 7 vans. The required trucks are estimated 89 currently without considering peak level. If we change the back haul rate from current 20% to 40%, 60% and 80%, how much would the cost drop? It was discovered that, if it is raised to 40%, 60% and 80%, the number of vehicle required will be reduced from 89 (current) to 76, 65 and 59. It was also discovered that the total savings will reduce down to 12%, 25% and 34%.

From the central East China Sea, a solenocerid shrimp (Haliporoides sibogae sibogae) and a nephropid lobster (Metanephrops armatus) are newly recorded into the Korean fauna. The former is the only member of the genus recorded in Korea. The latter extends its range from Tai Nan, northward to the central East China Sea. Brief comments on to fisheries interests and coloration are given for the two species.

Two porcellanid crabs collected from Jeju Island, Petrolisthes militaris (Heller, 1862) and P. coccineus (Owen, 1839) are recorded as new to Korean fauna. Hence, the Korean porcellanid crabs consist of nine species of seven genera and the genus Petrolisthes now contains three described species.

A new method of automatic recording raingauge is developed to measure rainfall with 0.01mm resolution. This use two different signals to measure rainfall more accurately compare than other raingauges. One is weight of the tipping bucket with rainfall amount and the other is pulse from tipping bucket reverse. New method applied 1 mm tipping bucket mechanism and install loadcell under tipping bucket mechanism for measuring rainfall weight. Loadcell measure weight of rainfall until 1 mm with 0.01 mm resolution and more than 1 mm than bucket reverse and pulse signal generate, after that loadcell measure weight again. The validation of new instrument was examined in the room 65 mm/hour rainfall rate total 53 mm range. There is below than 1 % error of absolute rainfall amount and 0.01 mm resolution. The field test of instrument was carried out by comparing its measured values with values recorded by weight type and standard type on June 1 2003 at Terrestrial Environmental Research Center at Tsukuba University in Tsukuba of Japan, when it has recorded total amount of 40.58 mm rainfall by standard raingauge and new raingauge recorded 41.032 mm. Same rainfall intensity pattern observed in field observation with weight type raingauge. Rainfall intensity between weight type and Lee-A type raingauge reached 0.9947 correlation in 3 minute average.

The present study summarized the occurrence, distribution and autecology about 31 taxa of the green algae (Chlorophytes) collected from several swamps, reservoir and highland wet-lands in the South Korea from 2010 to 2013. This paper deals with a total 31 taxa including of 26 genera which are recorded for the first time in Korea. Among these algae, 18 genera including Pyrobotrys Arnoldi, Volvulina Playfair, Dicellula Svirenko, Echinocoleum Jao & Lee, Hofmania Chodat, Gloeotila Kutzing, Tetrachlorella Korschikov, Botryospherella P.C.Silva etc., were newly recorded in Korean fresh-water algal flora.

The present study summarizes the taxonomic description and Korean distribution of 16 taxa that are recorded for the first time in Korea. These taxa classified into Chlorophyceae (Astrephomene gubernaculifera, Botryococcus protuberans, Chlorangiella polychlora, Cylindrocapsa geminella, Kirchneriella contorta var. gracillima, Korshikoviella gracilipes, Oocystis naegelii, O. ovalis, Stylosphaeridium stipitatum), Charophyceae (Cosmarium moniliforme, Cosmocladium constrictum, C. perissum), Xanthophyceae (Tetraedriella tumidulum, T. spnigera), Chrysophyceae (Cyclonexis erinus) and Cyanophyceae (Arthrospira platensis). Among these taxa, six genera including Astrephomene, Chlorangiella, Cosmocladium, Cyclonexis, Stylosphaeridium, and Tetraedriella are newly recorded in Korea.

One of the small genera of the tribe Atrophini (subfamily Banchinae), the genus Amphirhachis, has been reported seven species in the world. Among them, four species (Amphirhachis fasciata, A. nigripalpis, A. rubriventris and A. tertia) from Oriental region, and four species(Amphirhachis fujiei, A. miyabi, A. nigra and A. tertia) from Eastern Palaearctic region. Unfortunately, there are no records in South Korea yet. This genus is easily distinguished from other genera of Atrophini following: clypeus strongly convex near side; posterior transverse carina of propodeum represented by a weak or faint vertical ridge at apex on each side; ovipositor sheath shorter than metasoma. In this study, the genus Amphirhachis is recorded for the first time with a newly recorded species (Amphirhachis tertia) from South Korea. New data on the taxonomy and distribution of Amphirhachis tertia are given. We also provide diagnosis and digital images of a newly recorded genus and species.
