A single specimen of Brama orcini (267.0 mm standard length, SL), belonging to the family Bramidae, was collected by purse seine from Jeju Strait, Korea, in December 2013. The specimen is characterized by having 16 gill rakers, 54 lateral line scales, and 36 vertebrae. B. orcini is distinguished from the most similar species, Brama japonica, by the number of lateral line scales (52-54 in B. orcini vs. 65-75 in B. japonica). We propose a new Korean name "Keun-bi-neul-sae-da-rae" for B. orcini.

A single specimen of Carangoides hedlandensis was collected from a set net installed at 25 m depth near Sangju Beach, Namhae, Gyeoksangnamdo, Korea. The morphology of the species was similar to that of C. armatus. Carangoides hedlandensis and C. armatus can be clearly distinguished by the number of gillrakers on the first arch: C. hedlandensis has 20-28 gillrakers whereas C. armatus has 30-39. Unlike other species, interorbital region of the head in C. hedlandensis is bumped. We suggest that C. hedlandensis should be added to lists of Korean fish fauna, and propose a Korean name, "Hokjeon-gaeng-i" for this species.

This is the first report of Snyderina yamanokami, from the subfamily Tetraroginae of the family Scorpaenidae, collected in Korea. The specimen (175.3 mm long) was caught in the coastal waters of Jeju Island on a commercial longline hook on 9 September 2009. This species is characterized by the following morphological traits: 9-11 dorsal fin rays, 5-6 anal fin rays, 13-15 pectoral fin rays, 5 ventral fin rays, pectoral fin tip reaching or extending past the origin of the anal fin, palatines toothless, and four dark spots on the middle of the body. We suggest a new Korean name, "Keun-mi-yeok-chi," for S. yamanokami.

The genus Chrysothrix is very common around the world and easy to be recognized by its bright yellowish granular thallus. In this study, investigations of lichen mycota in South Korea and Chile from 2010 to 2017 have been done, and some Chrysothrix specimens were collected, based on the morphological and chemical study on these specimens, five species were confirmed in this study, including one new species from Chile, Chrysothrix chilensis D. Liu & J.-S Hur, and one new record from South Korea, C. xanthina (Vain.) Kalb. Meanwhile, detail description and illustration for each species were present in this study.

Recently, as most companies recognize the importance of the customer relationship management, they strongly believe that they must know who their customers are. The job of a customer is very important information for us to understand the customer. However, since most customers are reluctant to reveal themselves, they do not let us know their jobs, and even provide false information about their jobs. The target domain of our research is mobile telecommunication. In this research, we developed a system that identifies the customer's job by utilizing the Call Detailed Record. From the Call Detailed Record, we extracted such variables as 'Average Monthly Payment'and 'Age of the Customer'and so forth. Moreover, we generated many summary variables and derived variables such as 'Number of Calls during Work Hours in Weekday', and 'Ratio of Calls from other Mobile Telephone'. Using artificial neural networks, we developed a two-step Job Identification System. In the first step, it identifies the four job classes then in the second step, it subdivides these four job classes into seven jobs. The accuracy of identifying the seven jobs was 69.1%.
