The fish community and introduced fish were surveyed at eight stations of Lake Soyang from March to October, 2013. A total of 41 species of twelve families were collected from the survey stations and among them, two species: Hemibarbus mylodon and Siniperca scherzeri (albino type) were identified as natural monument. There were fifteen Korean endemic species (36.6 %) including Acheilognathus yamatsutae. When compared with previous data (2003), A. yamatsutae, Pseudorasbora parva, Sarcocheilichthys nigripinnis morii, Sarcocheilichthys variegatus wakiyae, Orthrias nudus, Leiocassisuss ussuriensis, Oncorhynchus mykiss, and Micropterus salmoides appeared new in the lake. Dominant species were Hypomesus olidus (St. 1, 3, 6, 7, 8), Lepomis macrochirus (St. 2, 4) and Zacco platypus (St. 5). Of the 12 introduced species fishes in Lake Soyang, Anguilla japonica, Hemiculter eigenmanni, H. nipponensis, Rhinogobius giurinus and Tridentiger brevispinis were introduced and released from other native river water zones in Korea but Cyprinus carpio (Israeli type), Carassius cuvieri, O. mykiss, Ictalurus puntatus, L. macrochirus, and M. salmoides originated from foreign countries.

The autochthonous and allochthonous organic carbon loading were measured in Lake Soyang, to estimate the amount of carbon loading into the lake and the contribution of their sources to tile lake's carbon loading. Autochthonous carbon loading was estimated from phytoplankton primary production with the extracellular organic carbon (EOC). Allochthonous loading was determined by measuring dissolved organic carbon (DOC) and particulate organic carbon (POC) concentration in the main inflowing Soyang River. Both autochthonous and allochthonous organic carbon loading were high during the svmmer, from July to September, and accounted for 43.2% and 71.7% of the annual loading, respectively. Primary productivity was elevated up to $1,000\;mgC\;m^{-2}\;d^{-1}$ during summer and lowest in winter. EOC production from phytoplankton was also large in summer, resulting in a high DOC concentration in the lake water. Primary production of phytoplankton and allochthonous organic matter loading from the watershed contributed to 53.6% and 46.4% of total loading, respectively. The EOC production accounted far $4.4{\sim}21.2%$ of POC primary production, implying that EOC production of phytolankton must be considered in estimation of primary production.

1. Introduction Community medicine with the concept of comprehensive medical care and an ideal medical care delivery system not only for an individual or family but for the whole community has emerged. In April 1970, the Presbyterian Medical Center started a hospital based community health service project in order to improve the health of the people in rural areas. Prior to commencing a comprehensive medical care system, a family survey was needed. The major objective of this survey was to obtain information concerning the people and their environment so as to be able to plan and implement a comprehensive medical care program in Soyang-Myun. 2. Survey Method An interview using a family record form was carried out for each household. This family record form was designed to get information about demography, family planning, environmental sanitation and vital statistics. Prior to beginning, the members of the survey team were trained in interviewing techniques for three days. The team consisted of a public health nurse, four nurse-aides, a sanitarian and four health extension workers who are working in our project, The survey was carried out during the period November 1971 to March 1972. 3.

To elucidate a part of phosphorus cycle an'd the nutritional status of phosphorus. the degradation rates of organic phosphate by phosphatase activity (PA). were studied at the water column of Lake Soyang. from March 1900 to April 1991. Phosphatase activity showed the range of 1-2220 nMillhr. Its maximum value was recortled on August and minimum during October and November. The PA and chlorophyll u v~luess howed high correlation coefficent (0.69). and the values of specific astivity was highest during Winter, 45-12\ulcorner nMihripg chl. a, and lowest on October. 2 nMl hripg chl. 11. The values of PA and bioavailable dissolved inorganic phosphate (DIP) showed negative correlation in surface water. During destratification period (Oct. and Nov. 1990). the values of PA were about 11240 times lower than those during August albeit high concentration of chlorophyll a (1.7- 7.2 mglm'). Such results seem to be cause'd by DIP supply from the metalimnion. hypolimnion ant1 sediment. With these results. phosphate was sufficient to sustain the biomass in Autumn. and internal loading of phosphate shoultl accelerate the eutrophication in Lake Soyang.

The objective of this study is to test the flood forecasting capability of TOPMODEL on a single watershed in Korea. The selected study area is the Soyang River basin with outlet at Soyang Dam site. The three daily hydrographs and the three hourly flood events during 1990~1996 are selected for model calibrations and performance tests. The model parameters are estimated on 1990 daily event by manual fitting technique and the effects of topographic index distribution to river flow simulations are investigated on the study area. The model performance on correlation coefficient between the observed and the simulated flows for the verification periods are above 0.77 on the 95-, 96-daily events, while above 0.87 for 90-, 95-, 96-hourly events. By the consideration of flood flow characteristics in Korea, the physical interpretation of the model concept, and the model performance, it can be concluded that the TOPMODEL is feasible as a flood forecasting model in Korea.

Objectives Sasang constitutional medicine is a traditional Korean medicine that classifies humans into four constitutions in consideration of individual differences in physical, psychological, and physiological characteristics. In this paper, we proposed a method to classify Taeeum person (TE) and Non-Taeeum person (NTE), Soeum person (SE) and Non-Soeum person (NSE), and Soyang person (ST) and Non-Soyang person (NSY) using a convolutional neural network with only facial images. Methods Based on the convolutional neural network VGG16 architecture, transfer learning is carried out on the facial images of 3738 subjects to classify TE and NTE, SE and NSE, and SY and NSY. Data augmentation techniques are used to increase classification performance. Results The classification performance of TE and NTE, SE and NSE, and SY and NSY was 77.24%, 85.17%, and 80.18% by F1 score and 80.02%, 85.96%, and 72.76% by Precision-Recall AUC (Area Under the receiver operating characteristic Curve) respectively. Conclusions It was found that Soeum person had the most heterogeneous facial features as it had the best classification performance compared to the rest of the constitution, followed by Taeeum person and Soyang person. The experimental results showed that there is a possibility to classify constitutions only with facial images. The performance is expected to increase with additional data such as BMI or personality questionnaire.

Drought is an environmental disaster typically defined as an unusual deficiency of water supply over an extended period. Satellite remote sensing provides an alternative approach to monitoring drought over large areas. In this study, we monitored drought patterns over about 30 years (1985-2015), using satellite imagery of Lake Soyang, Gangwondo, South Korea. Landsat images were classified using ISODATA, maximum likelihood analysis, and an artificial neural network to derive the lake area. In addition, the relationship between areas of Lake Soyang and the Standardized Precipitation Index (SPI) was analyzed. The results showed that the artificial neural network was a better method for determining the area of the lake. Based on the relationship between the SPI value and changes in area, the R² value was 0.52. This means that the area of the lake varied depending on SPI value. This study was able to detect and monitor drought conditions in the Lake Soyang area. The results of this study are used in the development of a regional drought monitoring program.

1. Objectives: This investigation compares the eating behaviors across normal-weight male groups of different Sasang constitutional types. 2. Methods: We recruited 31 male participants aged 20-35 with BMI 18.5-23. The eating behavior was assessed using Gastrointestinal Symptom Rating Scale (GSRS), Bulimia Test Revised (BULIT-R), Korean Version of Eating Attitude Test-26 (KEAT-26), and Dutch Eating Behavior Questionnaire (DEBQ). 3. Results: 1) Assessments made by GSRS, KEAT-26, and BULIT-R were not significantly different across different Sasang constitutional types. (p<0.05) 2) The Soeum group showed significantly lower BMI and body weight compared to the Soyang and Taeeum groups. 3) The Emotional eating subscale of DEBQ differed significantly across different Sasang constitutional types. (p<0.05) 4) The Soeum group showed a significantly lower Emotional eating subscale score of DEBQ compared to the Soyang and Taeeum groups. 4. Conclusions: The results of this study suggest that emotional factors could influence eating behaviors differently across different Sasang constitutional types, in which the Soeum type is less affected than the Soyang type by emotional states.

This study aims to analyze the difference of eating habits in accordance with Sasang Constitution types. For this study, 249 persons were interviewed and surveyed, classified into Taeyang(8.4%), Soyang (19.3%), Taeeum(26.5%), and Soeum(45.8%). As for taste preference, people of the Taeeum and Soyang body constitution types tended to prefer spicy tastes while those of the Taeyang and Soeum body constitution types preferred sweet tastes. For eating habits, people of the Taeeum and Soyang body constitution types stated that they eat food relatively quickly and eat food until they feel full. They also said they normally overeat when they get stressed. The eating habits for the four groups, there was a significant difference(p<0.05) between body constitution types and eating habits. We hope that our research will provide the food service industry with helpful and new information.
