The potato tuber moth (Phthorimaea operculella Zeller ) was surveyed for its distribution and damage to tobacco plants in field. The insect was found in all four localities examined ; Dalseong and youngdeog of Gyeongbuk Province, and Boseong and Jindo island of Cheongnam Province. About half of the tobacco plants examined contained the larvae with the highest level (76.7%)of larvae infestation in the Jindo island. In a given tobacco plant the larvae were concentrated on the first three leaves, from bottom, with 82.4 5 of the total number, and a single leaf usually has one to three larval.

This study was performed to develop ethogram of the Jindo dog's temperament categories under various conditions. A set of 12 behavioral tests were developed to investigate temperament categories expressed by the dogs. Fourty-three adult Jindo dogs(24 males, 19 females) from three different farms located in Jindo island were tested in 12 different behavioral tests. All test procedures and dog's behaviors responded to the tests were recorded using two digital video cameras and one digital still camera. A single observer reviewed all of the videotapes focused on dog's vocalization, movement, head, ears, eyes, mouth, and tail-positions. After all of the behavioral variables expressed throughout the testing period were described in detail, an ethogram of four temperament categories of 'sociability', 'aggression', 'fearfulness', and 'submission' revealed by 12 behavioral tests was developed.

We examined monthly changes in the rate of fishes by-caught by gape net with wings and their immature ratio in the coast of Yeosu and Jindo Island, Korea. A minus correlation between bycatch rate, the ratio of fishes except for anchovy, Engraulis japonicus, to all fishes collected by gape net with wings, and individuals of the collected anchovy was significantly observed, implying that as the anchovy catch decreased and the bycatch rate increased. Immature ratios by the dominant bycatch species during the study is the following; Leiognathus nuchalis was 72.7~99.0%, Sphyraena pinguis was 84.0%, Sardinella zunasi was 90.0%, others (Leptocephalus, Trichiurus lepturus, Ammodytes personatus, Sphyraena pinguis, Trachurus japonicas, Mugil cephalus and Erisphex pottii) were 100.0%. In order to decrease the high bycatch rates of immature fishes in spring and autumn, our study suggested increasing of codend mesh size and developing suitable bycatch reduction devices in a gape net with wings.

According to the 4th BPE(Basic Plan for long-term Electricity Supply and Demand), Electricity demand of Jeju island in 2012 will be reached to 682MW. Jeju island will be faced with severe shortage of electricty, also needed to find transport route to supply green energy which will be made from "Carbon free island" energy policy toward land at that time. For that reason, The plan which construct 400MW size HVDC connection line was decided for potential supply stabilization and transportation of green energy. KEPCO organized special construction office not only to observe the successful project completion which aims 2011 December but also to build up professional manpower. KEPCO is putting spur to the HVDC project these days. Construction site of converter stations has been already confirmed and contracts of cable, converter have done as per turn-key early this year. On this report, we would like to discuss about project scheme, main characteristics of system, and the furture progress plan of "Jindo~Jeju HVDC construction project expecially converter station part" which is being pushed by KEPCO.

The medicinal plants in 22 unhabited islands of Jindo-gun, Chonnam provincde were investigated from March 2000 to October 2002. The medicinal plants in 22 uninhabited islands of Jindo-gun were consisted 366 taxa; 95 families, 269 genus, 309 species, 52 varieties, 3 forma, and 2 subspecies. Important medicinal plants on survey area were Lemmaphyllum microphyllum, Dendropanax morbifera, Ficus erecta, Farfugium japonicum, Machilus thunbergii, Juniperus chinensis var. procumbens, Dendrobium moniliforme, Pyrrhosia tricuspis, Cinnamomum japonicum, Pittosporum tobira, Kadsura japonica, and Daphniphyllum macropodum, This result can be used as basic information data for medicinal research and the conservation of uninhabited islands.

Two hypotrichous ciliates inhabiting the representative terrestrial habitats of Jindo Island, Holostichides chardezi Foissner, 1987 and Rigidocortex octonucleatus (Foissner, 1988) are found from Jindo Island. These two species are newly recorded from Korea. The description was based on the observation of living specimens, protargol impregnated specimens and biometric analysis. The morphological variations among the populations of these species were investigated with morphometry. The diagnostic characteristics of these species are as follows: Holostichides chardezi : elongate body flexible and twisted, yellowish subpellicular granules scattered entire cortex, adoral zone of membranelles covering about $28\%$ of body length, left and right rows of mid-ventral cirri paired, left row ended at buccal vertex and right row extending to center of body, no transverse cirri, both marginal rows of cirri not confluent at posterior end, 28-42 macronuclei and 1-5 micronuclei scattered entire body. 3 caudal cirri and 4 dorsal kineties. Rigidocortex octonucleatues: elongate-oval body rigid and not contractile, yellowish cytoplasmic crystals and fat globules densely packed, adoral zone of membranelles covering about $40\%$ of body length, 5 transverse cirri, both marginal rows of cirri not confluent at posterior end, 8 macronuclei longitudinally arranged in median of cell, 3 caudal cirri and 7-10 fragmented dorsal kineties.

Two Spirostomum species were collected from freshwater in Jindo Island, Korea and identified as Spirostomum ambiguum (Muller, 1786) Ehrenberg, 1835 and Spirostomum minus Roux, 1901. This study is the first known morphological record of these two species being found in Korea. The description is based on the observation of living specimens and protargol impregnated specimens. Diagnostics of Spirostomum ambiguum: body size $340-930{\times}45-80{\mu}m$ in vivo; long and slender body with truncated posterior part; macronucleus moniliform with 7-22 nodules; cortical granules irregularly arranged 4-5 rows in between somatic kineties; 24-58 somatic kineties arranged longitudinally; adoral zone of membranelles (AZM) covered about 60-80% of body length. Diagnostics of Spirostomum minus: body size $500-730{\times}35-45{\mu}m$ in vivo; long and slender body with truncated posterior part; macronucleus moniliform with 11-16 nodules; micronucleus 20-37 oval shape; cortical granules regularly arranged 3-4 rows in between somatic kineties; 20-30 somatic kineties arranged longitudinally; AZM covered about 40-50% of body length with 120-150 adoral membranelles.

A new marine interstitial nematode species belonging to the subgenus Quadricoma of order Desmoscolecida is described from Jindo Island, South Korea. The new species, Tricoma (Quadricoma) jindoensis sp. nov., is most allied with T. (Q.) crassicomoides Timm, 1970 in sharing the similar cephalic setae, broadly truncated border of head, lip region including 6 labial papillae, and slender and long spicule among the seven congeners with 44 quadricomoid rings. However, T. (Q.) jindoensis differs from it by the globular protuberance on the penultimate ring, 7 tail rings, and 9 pairs of subdorsal setae in male. This is the first record of Quadricoma nematodes from East Asia.

Paradexamine jindoensis n. sp. belonging to family Dexaminidae was collected from Jindo Island, Korea. The new species is fully illustrated and compared with related congeners. The new species resembles highly P. houtete, in having the tooth formulae of dorsal pleonites, 1-3-3-3, rear to front and in bearing short spines on the mandible. However, it is characteristic in having the several morphological differences of mouth parts, slender appendages, and longer peduncular article 2 of antenna 1 than article 1.
