The spatial distribution and abundance of fish species was estimate near Dok-do, East Sea of Korea by conducting midwater trawl survey with hydroacoustic method. Acoustic and midwater trawl data were collected onboard the R/V Tamgu 21 during 7-8 March 2016. Acoustic data were collected at the frequencies of 38 and 120 kHz and converted to nautical area scattering strength ($m^2/nmile^2$). Species are distributed mainly over an extent of 30-55 m, generally around southwest of Dok-do; the squid Watasenia scintillans was the dominant species found. The length-weight function and target strength of squid and other fishes were used to estimate the W. scintillans stock at 2499.1 tons and other fish at 43.8 tons during the winter season. The hydroacoustic method offers an approach for the determination of the biomass and vertical and spatial distributions of species aggregating near Dok-do, East Sea of Korea.

This study investigated the spatial characteristics of warming trends and the dipole-like pattern of temperature field in the Antarctic Peninsula using surface air temperature (SAT) of 10 stations in the vicinity of the Antarctic Peninsula. SAT data for the 1962-2001 period at 6 stations (Rothera, Faraday/Vernadsky, Bellingshausen, Orcadas, Esperanza, Halley) revealed in general the larger warming trends in autumn and winter except for Halley. The largest warming was shown for August in the west side of the Peninsula (more than $0.9^{\circ}C/decade$). On the other hand, the recent 14-year SAT data showed the strong warming trends at 9 stations except for Halley in the earlier period (April-June) than August for the 1962-2001 period. The largest warming appeared in May at Esperanza and Butler Island. SAT of the two sides showed significant positive correlations over most of the period except for the mid- and the late 1970s, in which significant negative correlations were found. In the correlation analysis between SAT and sea surface temperature (SST) anomalies in the NINO 3.4 region, strong negative correlation was found in the west side of the Peninsula. Details of the correlation analysis exhibited that the negative correlation was significantly strong from the early 1980s to the mid-1990s. However, it was difficult to find significant correlations of ENSO with SAT in the east side of the Peninsula. So, in this study it failed to find out clearly the out-of-phase relationship of SAT across the Antarctic Peninsula.

This study analyzed characteristics and tendencies of seasonal change on shoreline and beach with 8 beaches at East Sea coast by topographical survey for 2 years from March 2012 to February 2013. The shorelines of East Sea coast appeared that amount of seasonal change was bigger than amount of annual change. The seasonal change tendencies between Gangwon-do and Gyeongsangbuk-do coast areas existed some regional differences. To synthesize seasonal changes on 8 beaches of East Sea coast, shoreline advance and beach deposit showed clearly in summer and shoreline retreat and beach erosion showed clearly in autumn. This result is different from tendencies of seasonal change in many mid-latitude coast areas of the world, but generally corresponds with reference studies in west coast and east coast. The major factor of beach erosion showing mostly in summer is storm wave caused by typhoon. The beach erosion by storm wave also occurred in late winter. And it assumes that the beach deposit showing mostly in autumn is result of equilibrium processes of coast area against strong erosion in summer.

Purpose: The purpose of this study was to examine the effect of Kynesio-taping therapy (KTT) on chronic joint pain among community-dwelling older adults. Methods: A pre-experimental design was used. KTT was employed on 23 consenting community older adults visiting a community center. KTT was applied on the painful joint for 3-4 days. Pain was evaluated using the visual analogue scale. Results: Frequent locations of pain were waist (43.8%), knee (28.1%), shoulder (12.4%), and head (9.4%). Time of severe pain during the day was mid-day (47.8%), early morning (21.7%), and evening (13.0%). Pain relief management included hospital visitation (65.2%), medication (17.4%), and application of a poultice (13.0%). Pain scores were significantly decreased after KTT compared to pretest scores acquired prior to taping (p<.001). Conclusions: KTT is a cost-effective, easy-to-use, and effective form of pain relief in older adults with chronic joint pain. Clinical practitioners can consider KTT as a complementary method of chronic pain control in older adults.

Acoustic surveys were conducted in the seas surround the South Korea (South Sea A, South Sea B (waters around the Jeju Island), West Sea and East Sea) in spring and autumn in 2016. First, the vertical and horizontal distributions of fisheries resources animals were examined. In most cases vertical acoustic biomass was high in surface water and mid-water layers other than South Sea A in autumn and West Sea. The highest vertical acoustic biomass showed at the depth of 70-80 m in the South Sea A in spring ($274.4m^2/nmi^2$) and the lowest one was 10-20 m in the West Sea in autumn ($0.4m^2/nmi^2$). With regard to the horizontal distributions of fisheries resources animals, in the South Sea A, the acoustic biomass was high in eastern and central part of the South Sea and the northeast of Jeju Island ($505.4-4099.1m^2/nmi^2$) in spring while it was high in eastern South Sea and the coastal water of Yeosu in autumn ($1046.9-2958.3m^2/nmi^2$). In the South Sea B, the acoustic biomass was occurred high in the southern and western seas of Jeju Island in spring ($201.0-1444.9m^2/nmi^2$) and in the southern of Jeju Island in autumn ($203.7-1440.9m^2/nmi^2$). On the other hand, the West Sea showed very low acoustic biomass in spring (average NASC of $1.1m^2/nmi^2$), yet high acoustic biomass in the vicinity of 37 N in autumn ($562.6-3764.2m^2/nmi^2$). The East Sea had high acoustic biomass in the coastal seas of Busan, Ulsan and Pohang in spring ($258.7{\sim}976.4m^2/nmi^2$) and of Goseong, Gangneung, Donghae, Pohang and Busan in autumn ($267.3-1196.3m^2/nmi^2$). During survey periods, fish schools were observed only in the South Sea A and the East Sea in spring and the West Sea in autumn. Fish schools in the South Sea A in spring were small size ($333.2{\pm}763.2m^2$) but had a strong $S_V$ ($-49.5{\pm}5.3dB$). In the East Sea, fish schools in spring had low $S_V$ ($-60.5{\pm}14.5dB$) yet had large sizes ($537.9{\pm}1111.5m^2$) and were distributed in the deep water depth ($83.5{\pm}33.5m$). Fish schools in the West Sea in autumn had strong $S_V$ ($-49.6{\pm}7.4dB$) and large sizes ($507.1{\pm}941.8m^2$). It was the first time for three seas surrounded South Korea to be conducted by acoustic surveys to understand the distribution and aggregation characteristics of fisheries resources animals. The results of this study would be beneficially used for planning a future survey combined acoustic method and mid-water trawling, particularly deciding a survey location, a time period, and a targeting water depth.

Based on the Expendable Bathythermograph (XBT) observation and serial oceanographic observation of National Institute of Fisheries Science (NIFS) during July 2013 to July 2015, we examined the temperature variation in the Ulleung Warm Eddy (UWE) in the East Sea. The UWE was always shown during the observation periods even though it was not the whole shape. The coefficient of variation (CV) was largest in the depth of 250 m at the side of the east coast of Korean Peninsula with $3{\sim}4^{\circ}C$ in temperature. CV of the horizontal distribution at 250 m depth was also largest in the region biased along the east coast of Korea. The warm eddy moved not only to the east-west direction but also to the north-south direction in the viewpoint of horizontal distributions of temperature. This region between the Korean Peninsula and Ulleung island also is the passage of the East Korean Warm Current. This means that interaction between the East Korean Warm Current and periphery of warm eddy makes large in the variation of movement along the east coast of Korean Peninsula. The largest variation of temperature at 250 m depth seemed to be significantly correlated with the East Sea Intermediate Water (ESIW) underlying Ulleung Warm Eddy. It is suggested that the interaction between the ESIW and UWE is active in the mid-depth along the periphery of UWE.

Elderly people comprise an increasing proportion of the population, and nutritional impairments may contribute to health problems among this group. This study was conducted to evaluate the nutritional status by Mini-Nutritional Assessment (MNA) and to identify relationships among anthropometric measurements, biochemical indicators, bone Mineral Density (BMD) and MNA results among older adults (${\geq}$65 yrs, n=98, 66.7${\pm}$2.5 yrs; M=52, F=46, BMI 24.5${\pm}$2.8 $kg/m^2$) at a Health Care Center. A dietitian administered MNA and collected anthropometric measurements (weight, height, waist circumference), biochemical indicators (albumin, hemoglobin, hematocrit, TLC, glucose, lipids) and the BMD (spine, femur, F=46). Subjects were grouped into a normal nutrition group (0~2 risk factors of malnutrition) and a high risk of malnutrition group (>=3 risk factors of malnutrition) based on their risk factor status for malnutrition. The risk factors for malnutrition include age ${\geq}$65 years, PIBW <90%, albumin <3.5 g/dl, TLC <1,500%, Hgb <14 g/dl (men), Hgb <10 g/dl (women), loss of appetite and weight loss 1~3 kg/last 3 months. In addition, subjects were grouped into a normal, osteopenia and osteoporosis group by BMD. We found that 12% of the subjects were at risk of malnutrition (MNA score, 21.4${\pm}$2.1) and that 88% were well nourished (27.3${\pm}$1.5) according to the MNA. Full-MNA scores were positively and significantly (p<0.05) associated with BMI, mid-arm circumference (MAC), calf circumference (CC), albumin and hemoglobin, respectively. The full-MNA score of the high risk of malnutrition group (23.0${\pm}$3.8) was lower than that of the normal nutrition group (27.0${\pm}$2.1) (p<0.05). In addition, the Full-MNA score was negatively associated with the risk factor of malnutrition (r=－0.35, p=0.0004). We found that 39.1% of the subjects had osteoporosis, 45.7% had osteopenia and 15.2% were normal according to their BMD. The MNA score of osteoporosis group (24.58${\pm}$3.3) was lower than that of the normal (27.4${\pm}$1.1) and osteopenia group (26.9${\pm}$1.5) (p<0.05). These results suggested that MNA can be useful as a nutritional screening tool of older adults in Health Care Centers.

This study explores the synoptic characteristics of cold days over South Korea and their relationship with large-scale climate variability. The cold day, which is different from cold surge, is defined when daily-mean surface air temperature, averaged over 11 KMA stations, is colder than 1-percentile temperature in each year by considering its long-term trend over 1960~2012. Such event is detected by quantile regression and the related synoptic patterns are identified in reanalysis data. Composite geopotential height anomalies at 500 hPa show that cold days are often preceded by positive anomalies in high latitudes and negative anomalies in midlatitudes on the west of Korea. While the formers are quasi-stationary and quasi-barotropic, and often qualified as blocking highs, the latters are associated with transient cyclones. At cold days, the north-south dipole in geopotential height anomalies becomes west-east dipole in the lower troposphere as high-latitude anticyclone expands equatorward to the Northern China and mid-latitude cyclone moves eastward and rapidly develops over the East Sea. The resulting northerlies cause cold days in Korea. By performing composite analyses of large-scale climate indices, it is further found that the occurrence of these cold days are preferable when the Arctic Oscillation is in its negative phase and/or East Asian monsoon circulation and Siberian high are anomalously strong.

Ssireum, the traditional Korean sport, is very popular at both amateur and professional levels. Ssireum players are prone to be obese which related to the chronic disease in their later life. The purpose of the study was to compare the anthropometric measurements, quality of diet, and blood parameters of Ssireum players with those of subjects who were matched body mass index, gender and age. Participants in the 3 groups, Ssireum players (SP, n=15), regular moderate exerciser (RME, n=15, >3 times /wk, >20 min/time) and intermittent light exerciser (ILE, n=14) groups. Anthropometric measurements included height, weight, fat mass (by Dual energy X-ray absorptiometry), lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), dietary variety score (DVS). Blood levels of lipids, leptin and insulin were analyzed. As a results lean body mass and mid-arm circumference were significantly higher in Ssireum players than those of other groups (p<0.01). Total body fat, trunk fat, abdominal skin fold thickness and waist-hip ratio were significantly lower in SP group than those of other groups (p<0.01). DVS were higher however, dietary quality was low in Ssireum players than in other groups. There were no differences among the 3 groups in regard to blood total cholesterol, LDL-cholesterol and glucose levels however, leptin level was low in Ssireum players. These results indicate that Ssireum players had significantly higher lean body mess and lower body fat when these were compared with regular moderate exerciser and intermittent light exerciser. Blood leptin levels of Ssireum players were low but blood lipid profiles were not significantly different.
