  • Experience API provides a learner-centered model for learning data collection and learning process recording. In particular, it can record learning data from multiple data sources. Therefore, Experience API provides very good support for ubiquitous learning. In this paper, we put forward the architecture of ubiquitous learning system and the method of reading the learning record from the ubiquitous learning system. We analyze students' learning behavior from two aspects: horizontal and vertical, and give the analysis results. The system can provide personalized suggestions for learners according to the results of learning analysis. According to the feedback from learners, we can see that this u-learning system can greatly improve learning interest and quality of learners.

  • Conchodytes nipponensis (De Haan, 1844), a caridean shrimp living in the mantle cavity of a pen shell (Atrina pectinata) is reported for the first time from Korea. It was collected from a depth of 15 m depth. Its morphology is described and illustrated, and a color image of a living specimen is provided. This is at the same time the first record of the genus Conchodytes, and the first record of a bivalve mollucs associated shrimp, from Korea.

  • Only four species of leuconids have been recorded in Korea, all belonging to the genera Eudorella Norman, 1867 and Nippoleucon Watling, 1991. In this study, Pseudoleucon japonicus Gamô, 1964 belonging to family Leuconidae Sars, 1878 is newly recorded for Korean cumacean fauna. Also, for the first time, the male of the species is fully described and illustrated. The specimens were collected from the exclusive economic zone (EEZ) in the western sea (Yellow Sea) of Korea, with a rectangular dredge during 2007-2008. This species is characterized by the following features: the carapace has strong serrations on the antero-lateral margin and a pair of short oblique ridges on the side surface; the ridges begin near the end of frontal lobe and merge with the dorsal median carina; the appendages, such as antenna 1, pereopod 2 and uropod have a lot of simple setae decorated with a bundle of hairs at the end. The present study represents the first record on the genus Pseudoleucon Zimmer, 1903 from Korea.

  • Three species of Choreutidae, Choreutis atrosignata (Christoph, 1888), Choreutis japonica (Zeller, 1877), and Litobrenthia japonica (Issiki, 1930), are reported for the first time from Korea. The records of C. atrosignata and C. japonica are based on two females from Yeongwol, Gangwon Province and from the Island Chujado, Jeju Province, respectively. The latter species was obtained from two larvae collected on the leaves of Ficus erecta (Moraceae). Photographs and data of rearing the larvae are provided. The record of L. japonica was based on two specimens collected from the Islands, Bogildo and Wando, Jeollanam Province. The present data of L. japonica represent the first record of the subfamily Brenthiinae and the genus Litobrenthia from Korea. Distributions of two species C. japonica and L. japonica, previously known only from Japan, now extends to Korea. Habitus and genitalia of the species treated here are briefly described and illustrated, if possible. To sum up, the Korean Choreutidae comprises four genera and 10 species, nine in Choreutinae and one in Brenthiinae.

  • In this study, we conduct a review of the genus Taeniogonalos Schulz, 1906, which belongs to the subfamily Trigonalinae (Hymenoptera: Trigonalidae) from Korea. The genus Taeniogonalos Schulz is recognized as a relatively small genus. Taeniogonalos comprises 53 described species worldwide, including nine species identified in the Eastern Palaearctic region. A total of four species have been recognized from Korea. This paper enumerates the known species in Korea, including the new record. We provide the diagnosis and photographs for the newly recorded species. Additionally, we present a key to the Korean species of Taeniogonalos Schulz, 1906.

  • A specimen of Arnoglossus polyspilus (G$\ddot{u}$nther) (229.0 mm standard length) belonging to the family Bothidae, collect from the coastal waters of Jeju Island, represents the first record of the species from Korea. This species is characterized by having caudal fin with two simple rays on both upper and lower margins, several anterior dorsal fin rays somewhat elongated, upper jaw extending to below anterior 1/3 of lower eye, and one gill raker on the upper limb of the first gill arch. We add this species to the Korean fish fauna and propose its new Korean name, "No-rang-ban-jeom-ga-ja-mi".

  • A single specimen (40.5 mm in SL) of Clariger chionomaculatus was collected at 4 m depth on mud bottom from off Geojedo Island, Korea. This species is characterized by having an elongated body without scales, several barbels below eyes, I, 12~15 second dorsal fin rays, I, 12~14 anal fin rays; 19~20 pectoral fin rays with one free soft ray on upper part, and a unique color pattern with numerous white blotches on dorsal part of body. Because it has been known from Japan only to date, we describe in detail C. chionomaculatus as the first record from Korea. A new Korean name, "Huin-jeom-wae-mang-dug", is proposed for the species.

It was identified as Lepadichthys frenatus by its having dorsal and anal fins with 17 and 13 rays, respectively, both fins connected to the caudal fin, and a reddish-brown body color. We describe the specimen as the first record from Korea, and propose a new Korean name "keun-ip-hak-chi" for the species.

  • In actual statistical surveys, the inconsistencies within the record are often occurred due to incorrect response. The users may be confused and statistical agencies may have a problem of reliability on statistical data in this case. It is needed to detect and correct the unconvinced record without any special reasons. However, it is not simple to determine which item should be corrected in every failed record. In this paper we briefly introduce Fellegi-Holt method, apply to a business survey, and then discuss the problems for this trial editing.
