A single specimen of the stone cockscomb, Alectrias alectrolophus (Pallas, 1811) was collected from off Gangneung-si, East Sea, Korea. The present Korean specimen is characterized in having a dermal crest on dorsal median line of head, LXIII dorsal fin rays, I, 44 anal fin rays, 68 vertebrae, slender and flexible dorsal spines in its anterior parts, and scales on the posterior portion of body, and fused gill membranes forming a free fold across the isthmus. We report A. alectrolophus based on a single specimen collected from the Korean water as the first record from Korea.

A single specimen of Liparis punctulatus (30.9 mm standard length) belonging to the family Liparidae, was collected in the waters off Busan on 4 August, 2016. This species is characterized by a single pair of nostrils, unlike other Liparis species. It is distinguished from L. ochotensis by the numbers of dorsal, anal, pectoral fin rays and the location of the gill opening (above the pectoral fin in L. punctulatus vs. extending ventrally in front of the pectoral fin). In the molecular analysis, 514 bp of 16S rRNA gene of the specimen in this study were identical to that of L. punctulatus from NCBI GenBank (K2P distance < 0.002). This is the first record of the species in Korea based on a voucher specimen, and we follow the Korean name "Kko-ma-kkom-chi" for this species proposed by Myoung et al. and Kim et al.

Purpose: This study was done to compare factors influencing children's self-esteem between two parent families and single parent families. Methods: The participants were 692 children aged 11 to 13 yr (388 in two parent families and 304 in single parent families) recruited from 20 community agencies and 5 elementary schools in Gyeonggi Province and Seoul City, South Korea. Data were collected from May to July, 2007 using a survey questionnaire containing items on self-esteem, internal control, problematic behavior, school record, family hardiness, parent-child communication and social support. The data were analyzed using SPSS 15.0 program and factors affecting children's self-esteem were analyzed by stepwise multiple regression. Results: Scores for the study variables were significantly different between the two groups. The factors influencing children's self-esteem were also different according to family type. For two parent families, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted $R^2$=.505, p<.001). For single parent families, social support, family hardiness, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted $R^2$=.444, p<.001). Conclusion: Nurse working with children should consider family type-specific factors influencing their self-esteem.

A single juvenile of the jawfish Stalix toyoshio (24.0 mm standard length) was collected from the South Sea of Korea at a depth of 135 m during box-corer sampling. The specimen was characterized by the absence of stripes on both the body and vertical fins, well-developed cephalic pore systems, yellowish body and fins, six transversely-forked dorsal fin spines, and five mandibular pores. Here, we describe the specimen, which represents the first record of S. toyoshio from Korea and the second record from the northwestern Pacific.

In this paper, we derive exact explicit expressions for the triple and quadruple moments of the lower record values from inverse the Weibull (IW) distribution. Next, we present and calculate the coefficients of the best linear unbiased estimates of the location and scale parameters of IW distribution (BLUEs) for different choices of the shape parameter and records size. We then use the higher order moments and the calculated BLUEs to compute the mean, variance, and the coefficients of skewness and kurtosis of certain linear functions of lower record values. By using the coefficients of the skewness and kurtosis, we develop approximate confidence intervals for the location and scale parameters of the IW distribution using Edgeworth approximate values and then compare them with the corresponding intervals constructed through Monte Carlo simulations. Finally, we apply the findings of the paper to some simulated data.

Managing electronic medical record is very difficult, because the currently electronic medical system is not designed standard that is uniform and proper. In this paper, in order to overcome this situation, we propose meta-data for the management of the electronic medical record as a single system. To this end, we first analyzed the research on electronic medical records and related standards. Second, we, on the basis of the analysis result, abstracted electronic medical record and entities related on electronic medical, and we designed an entity-relationship model. And finally, we have to complete the meta-data through the setting attributes in this entity-relationship model. Through this study, it was possible that we can complete metadata highly expressive medical records, and suggest an alternative for problem of current medical records systems.

In MySQL InnoDB, there are two ways of storing data. One is to create a separate tablespace for each table and store it separately. Another is to store all table and index information in a single system tablespace. You can use this information to recover deleted data from the record. However, in most of the current database forensic studies, the former is actively researched and its structure is analyzed, whereas the latter is not enough to be used for forensics. Both approaches must be analyzed in terms of database forensics because their storage structures are different from each other. In this paper, we propose a method for recovering deleted records in a method of storing records in IBDATA file, which is a single system tablespace. First, we analyze the IBDATA file to reveal its structure. And introduce delete record recovery algorithm which extended to an unallocated page area which was not considered in the past. In addition, we show that the recovery rate is improved up to 68% compared with the existing method through verification using real data by implementing the algorithm as a tool.

In the single sweep record of event-related potential (ERP), the peak latency of P300, which is one of the most prominent positive peaks in the ERP record, might fluctuate according to the recording conditions. The fluctuation of the peak latency (measurement fluctuation) is the summation of the fluctuation caused by physiological factor (physiological fluctuation) and one by noise of background EEG (noise fluctuation). We propsed a method for estimating the interval of the physiological fluctuation based on a limited number of single sweep records. The noise fluctuation was estimated by using the relationship between the signal-to-noise (SN) ratio and the noise fluctuation based on the P300 model and the background EEG model. The interval estimate of the physiological fluctuation were obtained by subtracting the interval estimate of the noise fluctuation from that of the measurement fluctuation. The proposed method was tested by using simulation data of ERP and applied to actual ERP and data of normal subjects, and gave satisfactory results.

A new record of Nomeus gronovii is described here based on a single specimen collected off the Jeju Island, Korea. The species has a blotched and spotted pattern on the body, 41 vertebrae, and a large pectoral fin with a white lower part. A molecular analysis of the partial (500 bp) cytochrome c oxidase subunit I gene showed that this specimen is closely related to specimens of N. gronovii collected in South Africa (Kimura-two-parameter distance = 0.006-0.012). A new Korean name, "Ga-neun-dong-gang-yeon-chi", is proposed for this species.

A single specimen (149.9 mm TL) of sagami grenadier, Ventrifossa garmani was collected from Korea waters. This species is similar to Coelorinchus spp. in body shape, but is distinguished by a short and rounded snout. It is characterized by having the serrated second dorsal spine in the first dorsal fin, a triangular spine on the scale, seven branchiostegal rays and six scales below middle of first dorsal fin. We describe this species as the first record to Korean fish fauna and propose the Korean name "Kkeo-kkeul-meo-ri-min-tae-sok" for this genus, and "Kkeo-kkeul-meo-ri-min-tae" for this species.
