Suitable design and operation of distillation process is very dependent on vapor-liquid equilibrium calculation. The usual calculation method is use binary interaction parameter. Flash points of n-propanol+n-butanol and 2-butanol+n-butanol were measured by Seta-flash closed cup tester. Experimental Flash points were compared with those calculated by the method based on Raoult's law and the optimization method using Wilson equation. The binary interaction parameters obtained by the optimization method are then used to calculate the bubble points of n-propanol+n-butanol and 2-butanol+n-butanol.

A new genus Goodingius is proposed to incorporate Hemicyclops adhaerens(Williams), H. arenicolae Gooding, H. elongatus Wilson and H. subadhaerens Gooding, all of which bear the six-segmented female urosome, three mandibular elements (or three elements plus one rudimentary setule), five setae on the first antennular segment, and no inner coxal seta of leg 4. The genus Giardella Canu, a sister taxon of Goodingius, is redefined as possessing eight elements on the third exopodal segment of leg 3, only a single inner seta on the second endopodal segment of leg 4, four spines on the third endopodal segment of leg 4. To the genus Giardella, Hemicyclops caissarum Kihara and Rocha and H. carinifer Humes are assigned, in addition to Giardella ricoensis n. sp., Giardella callianassae Canu, and G. thompsoni A. Scott. Keys to the species of both genera are provided.

Two species of the genus Isotomurus $B{\ddot{o}}rner$ are newly recorded in Korea; I. bimus Christiansen and Bellinger, and I. plumosus Bagnall. These species are collected from salt marshes near West Sea of Korea. The Korean materials of I. bimus agreed well with the original description by Christiansen and Bellinger from North America, in its peculiar body pattern, with two long ciliated setae on tibiotarsus of hind leg, multisetaceous lateral flap of ventral tube and the presence of a mucronal lateral seta. Isotomurus plumosus is also easily identified from other Isotomurus species by the peculiar colour pattern, and the presence of long maxillary lamella 1 and a mucronal seta.

The genus Eurycletodes Sars, 1909 is reported for the first time in Korea. A new species of the genus Eurycletodes was collected from Hansando Island, South Sea of Korea. So far, Eurycletodes comprises 27 species, with no previously recorded species reported in East Asia, including Korea. Eurycletodes (Oligocletodes) vadumus sp. nov. is morphologically most closely related to E. (O.) denticulatus Por, 1967, E. (O.) aculeatus Sars, 1920, and E. (O.) diva Menzel, 2011, but clearly distinguishable from the others based on the following morphological characteristics: absence of A2 exopodal seta, A1 last segment with two inner setae, P4 exp-3 proximal inner seta modified, the ratio of length and of caudal rami (1.6 times), and mandibular palp with three setae. Together with the new species, the number of valid species in this genus has risen to 28. A key to species of the genus Eurycletodes is provided.

Early zoeal stages of two snapping shrimps Alpheus digitalis De Haan, 1850 and Alpheus japonicus Miers, 1879 are described and illustrated in detail for the first time based on the laboratory-reared materials. The first zoeas of Alpheus are more related to those of Vexillipar than to Athanas, Automate, and Synalpheus by having rostrum absent, the tip of the endopod of the antenna with a long plumose seta as well as a spine, the endopod of the maxilla with a basal and two terminal setae, the exopod of the maxilla shorter than the endopod, and the endopod of the second maxilliped with a seta on the proximal segment. A list of larval descriptions and described stages of the Alpheidae reported from Indo-West Pacific waters are included.

A new halacarid species, Agaue laeviunguis n. sp. from Youngil Bay, Pohang City, South Korea is described. In sharing the character combination of three dorsal setae on PE, lacking dorsal seta anterior to insertion of leg IV, three ventral setae on PE, female PGS adjacent to GF, telofemora devoid of fovea, well developed smooth cerotegumental lamella on all telofemora, presence of accessory process on all lateral claws, long gnathosoma, and a smooth seta on P2 in both sexes, this species resembles A. subglabra Bartsch from Australia. The species, however, is clearly distinguished from A. subglabra by its larger body, claws of tarsi II-IV without ventral pecten, and much more PGS in female. Description of proto- and deutonymphs are also provided.

This Paper the state-of-the art indirect induction heated boiler and induction heated hot air producer using the voltage-fed series resonant high-frequency inverter whice can operate in the frequency range from 20kHz to 50kHz. A specially-designed induction heater composed of laminated stainless assembly with many tiny holes and interconnected spot welding points between stainless plates is inserted into the ceramic type vessel with external working coil connected to the inverter and tubelence fluid through this induction heater in moving fluid generates in the vessel. The operating performances of this unique appliance in next generation and its effectiveness are evaluated and discussed from a practical point of view.

The first zoea of R. uritai is described in detail, based on laboratory-hatched material. The first zoea of R. uritai can be distinguished from that of R. conspiciocellus and R. durbanensis by the rostrum downwards, overreaching distal margin of the outer flagellum of the antenna, the endopod of the antenna with short seta as well as long plumose seta distally, and the scale of the antenna six-segmented. The shape of the telson can be a distinguishing character of the first zoea of Rhynchocinetes from that of Cinetorhynchus.

A new species belonging to the genus Cyclopinopsis Smirnov, 1935 (Cyclopinidae) is described from Korea, as the third species of the genus. Specimens were collected by washing the subtidal sediments off Dokdo Island in the East Sea and the intertidal sands at Baegripo beach, Taean Peninsula on the Yellow Sea coast. Cyclopinopsis deformata n. sp. is characteristic and distinguished from its two congeneric species currently recognized, C. curticauda Smirnov, 1935 and C. brasiliensis Herbst, 1955 in having a deformed seta at the outer distal corner of the third exopodal segment of leg 4. The seta is supposed to be deformed from an outer spine on the third exopodal segment of leg 4, which has been known as completely lost in the genus until now. A character comparison table of the three species and a key to species of the genus Cyclopinopsis are provided herein.

The family Ameiridae Boeck, 1865 (Copepoda; Harpacticoida) consists of about 380 species in 47 genera, but only 10 species have been reported in Korea. A benthic ameirid species was collected from the East Sea of Korea. Specimens were identified as members of the genus Ameiropsis Sars G.O., 1907, and this is the first record of the genus Ameiropsis in the Pacific Ocean. Ameiropsis gyeongjuensis sp. nov. is morphologically similar to A. mixta Sars G.O., 1907 and A. longicornis Sars G.O., 1907 from Norway. However, the new species is clearly distinguishable from the others based on the following morphological characteristics: the proximal segment of antennary exopod with a bulge in the middle, and with one pinnate seta; the distal segment of antennary exopod with a thickened, blade-shaped outer seta; and female P5 baseoendopod with five setae and exopod with six setae. An identification key to species is provided for the 11 valid species of the genus Ameiropsis.
