Two sculpin specimens (79.3~100.8 mm standard length) were collected from the upper reach of Deokdongcheon Stream, a tributary of the Hyeongsangang River, in Korea. They were identified as Cottus pollux by characteristics such as the absence of palatine teeth, 12~13 unbranched pectoral fin rays, pelvic fins without obvious bands or spots, and the absence of a blackish band on the head or anterior part of the body. A phylogenetic analysis based on the nuclear ITS1 gene and mitochondrial cytb gene indicated that the specimens formed a clade with Japanese C. pollux, supporting the morphological species identification. We propose a new Korean name for the species: "Min-mu-nui-dug-jung-gae"

A single specimen of the genus Bothus (family Bothidae) was collected for the first time at the intertidal zone of Moseulpo Port, Daejeong-eup, Seogwipo-si, Jejudo Island, on 14 August 2022. The specimen was identified as Bothus pantherinus in having following morphological traits: dark spots and ring-shaped patterns near eyes and the pectoral fins, one distinct spot in the center of the lateral line, 75 lateral line scales, and seven hourglass shaped supracranial pterygiophores. As a result of analyzing 603 bp of mitochondrial DNA COI sequences, our specimen was perfectly matched to those of B. pantherinus registered in NCBI. It has been known that the species is widely distributed throughout the Indo-Pacific Ocean from Red Sea to Hawaiian (32 degrees north to 32 degrees south), but this study revealed that its distribution expanded to the waters of Jejudo Island (33 degrees north), Korea. We propose its new Korean name "Beot-kkoch-mu-nui-dung-geul-neob-chi".

PURPOSE: The purpose of this study was to examine the association of waist to height ratio (WHtR) and resting heart rate (RHR) with cardio-metabolic risk factors among Korean postmenopausal women. METHODS: A cross-sectional analysis was performed using the 2015 Korea National Health and Nutrition Examination Survey. The analysis included a total of 1,540 postmenopausal women. RESULTS: Individuals with higher WHtR (>0.56) showed significantly higher glucose, triglyceride, insulin, Homeostatic Model Assessment for Insulin resistance (HOMA-IR), total cholesterol, systolic and diastolic blood pressure compared with ones with lower WHtR (≤0.51). Similar findings were found in those with higher RHR (≥90 bpm) compared with ones with lower RHR (<60 bpm) for glucose and HOMA-IR. When determining the combined effects of WHtR and RHR on the prevalence of metabolic syndrome, individual with WHtR above 0.5 and RHR above 80 bpm showed 10.39 times higher prevalence of metabolic syndrome compared with those with WHtR below 0.5 and RHR below 70 bpm. We further performed multiple linear regression analysis to understand how WHtR and RHR contribute to fasting glucose, and found that both WHtR and RHR contribute to fasting glucose levels independent of age, education level, marital status and income level. CONCLUSIONS: The current study showed that the WHtR and RHR are associated with cardio-metabolic risk factor and prevalence of metabolic syndrome in Korean postmenopausal women.

The purpose of this paper is to propose a method to improve the performance of the previous research is characterized by recognizing facial gestures from the 3D coordinates of seven landmarks selected from the MediaPipe Face Mesh model, generating corresponding user events, and executing corresponding commands. The proposed method applied adaptive moving average processing to the cursor positions in the process to stabilize the cursor by alleviating microtremor, and improved performance by blocking temporary opening/closing discrepancies between both eyes when opening and closing both eyes simultaneously. As a result of the usability evaluation of the proposed facial gesture interface, it was confirmed that the average recognition rate of facial gestures was increased to 98.7% compared to 95.8% in the previous research.

The purpose of this study is to identify healthy family educational need and life satisfaction of middle school students and their parents. The data for the analysis were collected from 674 middle school students and 597 their parents living in Seoul using the structured questionnaire. Descriptive statistics, one-way ANOVA with Duncan test, and Pearson' correlation analysis were used to examine the data. The results indicated that the need for healthy family education of the middle school students was high. The students were interested in consumer economics and friend relationship, whereas their parents were interested in consumer economics and family relationship. Some of the demographic variables, such as gender, living area, and the amount of allowance, were the variables affecting the educational needs of students. There were relatively high correlation between healthy family educational need and life satisfaction, so educators should provide the healthy family education program to improve students' life satisfaction.

Studies of leisure time generally have been concentrated on the amount of time spent by each family member in Korea. In this study, the shared leisure time among family members in various leisure activities was mainly investigated. Purposes of this study were to describe how family members spent the leisure time together and to investigate the determinants that affected whether or not family shared leisure time together. The data source was the '2009 Time Use Survey' conducted by the Korea National Statistical Office. The person involved in each activity was surveyed for the first time in the survey. The data from 17,470 diaries(10,359 weekdays and 3,549 Sunday) from 8,745 individuals aged from 20 to 59 who had a spouse were analyzed. The descriptive statistics and logistic regressions were used. On average, married couples spent leisure time together with spouses 36 minutes a day on weekdays and 1 hour and 38 minutes on Sunday, respectively. Parent did with preschool children 5 minutes a day on weekdays and 15 minutes on Sunday, respectively. The shared leisure time with other family and relatives was 22 minutes a day on weekdays and 1 hour and 13 minutes on Sunday, respectively. Although there was a wide variation on the shared family leisure time by the types of activities, the main shared leisure activity was using mass media, which accounts for about two third of all shared leisure time together with family. Independent variables, including the age, sex, education level, working hours, personal income, presence of preschool children, marital status, sex role attitude, and dual or single income earner were the significant determinants of family's or couple's parent-preschool children's shared leisure time on weekdays or Sunday. Based on the results of this study, family and leisure policy were suggested to increase active family shared leisure time.

Objective: Infection is very common in the elderly, so there is a high prevalence of antibiotics use among this population. Especially, due to the emergence of resistant bacteria, the use of vancomycin is growing. The purpose of this study was to evaluate risk factors associated with vancomycin-induced nephrotoxicity in elderly patients. Methods: The subjects of this study were patients over 18 years old who received intravenous vancomycin in a general hospital located in Gangneung-si, Korea between August 1, 2013 and July 31, 2015. Data collection regarding vancomycin use and baseline characteristics was conducted using computerized hospital database. Logistic regression analysis was used to identify risk factors associated with vancomycin-induced nephrotoxicity. Results: A total of 290 patients were finally included, and 191(66%) out of these patients were age 65 or older. The incidence of vancomycin-induced nephrotoxicity was 11.0%, 12.6%, and 7.0% in the all adult patients, the elderly patients, and the non-elderly patients, respectively. There were significant differences in comorbidities between patients with nephrotoxicity and patients without nephrotoxicity in the all adult patients, and there were significant differences in vancomycin duration, comorbidities, and number of nephrotoxic agents between patients with nephrotoxicity and patients without nephrotoxicity in the elderly patients. However, according to the logistic regression analysis, there was no significant risk factor that increases the incidence of vancomycin-induced nephrotoxicity in all three age groups. Conclusion: There were no differences in risk factors that increase the incidence of vancomycin-induced nephrotoxicity between all adult patients, elderly patients, and non-elderly patients. Further studies with larger sample sizes to identify risk factors associated with vancomycin-induced nephrotoxicity in the elderly to improve the outcome of pharmacotherapy are required.

The bone of spinal animals has a hydroxylapatite ($Ca_{10}(PO_4)_6(OH)_2$, HAp) structure which is well known as an excellent inorganic ion exchanger for various heavy metal ions in solutions. In this study, the reusability of cow-bone, pig-bone and fish-bone as a potential material for the removal of heavy metals in solutions was evaluated from the removal of Cu(II) ion in batch tests. The surface properties of three bones, calcined at different temperatures, were measured with SEM, XRD, FT-IR analyses. From the SEM analysis, a clear development of heterogeneity as well as pores having small diameter was observed as the calcination temperature increased. The results of X-ray diffraction analysis showed well developed crystallinity on the surface of calcined bones obtained at higher temperatures, suggesting a transform of amorphous type to crystalline type. Fourier transform infrared (FT-IR) analysis showed disappearance of water molecule on the surface of HAp and organic functional groups of the HAp with increasing the calcination temperatures. Cu(II) removal in the control test was below 15%. By the way, additional 40% increase of Cu(II) removal was observed in the presence of calcined bones. For three bones, Cu(II) removal was decreased as the calcined temperature increased. Cu(II) removal was increased as the solution pH increased due to a favorable condition for the cation exchange as well as precipitation.
