This study investigated the physicochemical properties and acceptability of yellow layer cake prepared using various levels of wet-milled rice flour (RF). RF was used to substitute 0% (control group), 15% (RF-15 group), 30% (RF-30 group) and 45% (RF-45 group) of wheat flour (WF) to manufacture yellow layer cakes. The substitution of WF with RF showed no significant effect on the pH but decreased the specific gravity and viscosity of the batter. Baking loss rates ranged from 4.65% to 5.03%, showing no significant difference among samples. In the color measurement, the experimental groups showed higher redness (a) and yellowness (b) than the control group (p<0.05). The experimental groups showed lower gumminess and chewiness than the control group. According to the results of intensity measurement of sensory properties, the RF-30 and RF-45 groups showed stronger intensities for darkness, sweetness, moistness and softness than the control group. The acceptance test found that the RF-45 group had significantly higher or similar results for all acceptance attributes than the control group. These results indicate that RF addition as a replacement of WF at a ratio of 45% is optimal for producing yellow layer cakes.

In order to prevent collision accidents of ships, which has been increasing recently, research on artificial intelligence-based autonomously operated ships (Maritime Autonomous Surface Ship, MASS) is underway. However, most of the studies related to autonomous ships mainly target medium-to-large ships due to the size and cost of the autonomous navigation system, and the sensors used here have a problem in that it is difficult to mount them on small ships. Therefore, this paper provides a path tracking system equipped with GPS and IMU sensors for autonomous operation of small ships. GPS and IMU sensors are utilized to determine the exact position of the vessel, which allows the proposed system to manually control the small vessel model to create a path and then when the small vessel travels the same path. Use the Pure Pursuit algorithm to follow the path. As a result, In this research, it is expected that a lightweight and low-cost sensor can be used to develop an autonomous operation system for small ships at low cost.

The purpose of this study was to compare nutrient intake and food consumption by food frequency according to the obesity index of women college student in Kunsan. The subjects were 251 women college students who were randomly selected from Kunsan national university. Subjects were assigned to one of the following group based on BMI : underweight, normal weight and overweight. Nutrient intake and food consumption by food frequency were evaluated based on questionnaires and 24 hour recall method. The results were as follows. %RDA of calcium, iron and zinc of obese group were more than the underweight group(p＜0.05). %Fat was significantly correlated with the daily intakes of protein and vitamin E(p＜0.05). %Fat was significantly correlated with %RDA of energy, protein, vitamin E, vitamin B$_{6}$. RBW was significantly correlated with %RDA of iron. BMI was significantly correlated with %RDA of energy, calcium, phosphorus. The foods frequently consumed among students were cooked rice and gimchi. The frequencies of fish and mushroom were correlated with food behavior scores(p＜0.01). The frequencies of carbonated beverage(p＜0.01), hamburger & piazza, deep fried foods(p＜0.01), soybean curd fried fish cake(p(0.05) were correlated with nutritional knowledge scores.

This study was carried out to investigate characteristics of water quality and THMs formation in lake-waters at kunsan. Of the parameters examined for water quality, pH, alkalinity, SO$_4$$^{-2}$ and Co- reflected the characteristics according to the origin, geography and water source of lakes while COD, SS, T-P, T-N and chlorophyll-a corelatively reflected well the influence of pollution factors around factors around lakes. The result of water quality analysis showed that most lakes in Kunsan area have the severe eutropnication problem, especially in summer. In lake-waters, THMFP overally continued to increase until 48 hour with the reaction time and THMs formation was largely achieved within 24 hour of the reaction time. The average formation ratio were 68.2% for CHCl$_3$, 23.6% for CHCl$_2$Br, 7.6% for CHClBr$_3$ and 0.6% for CHBr$_3$respectively and much difference depending on the reaction time was not shown. Overally, 96h-THEFP levels in lakes were high during June~September and showed higher tencency in lakes where could be regarded more contaminated on the whole. These results suggest that THMFP may be available for the management of lake-water quality as one if the useful parameters for the general evaluation of contamination. 96h-THEMFP failed to show the strong corelation individually with pH, TOC, COD and chlorphyll-a.

A newly recorded species, Fimbristylis hookeriana Boeckeler, was found in Gyema-ri, Hongnongeup, Yeonggwang-gun, Jeollanam-do and Munyeo-do Is., Gunsan-si, Jeollabuk-do, Korea. Fimbristylis hookeriana is closely related to F. dichotoma, which has ovoid spikelets, deciduous scales, pubescent culms, and short style. However, this species is distinguished by very narrowly ovoid spikelets, persistent scales, glabrous culms, and long style. We propose a new Korean name, 'Ba-Wi-Ha-Neul-Ji-Gi', meaning that this inhabits on dried rocks near seashore. Redescription, illustrations, photographs, table, and a key to species of the Fimbristylis Vahl in Korea are provided.

The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI) : underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.

Mass mortality occurred in mud loaches, Misgurnus mizolepis, cultured in ponds located in Kunsan. External signs of affected fish showed hemorrhage of skin and fins, Internally, pale liver with congestion, enlarged kidney, and spleen and enteritis exhibited. Causative bacteria isolated from liver, spleen, and kidney of the disease fish. In biochemical tests, the isolates were similar with those of the reference strains, A. sobria. The aerolysine gene from the present isolate was amplified PCR with the primer SOBF and SOBB for A. sobria. The isolate was identified as A. sobria on the basis of those tests. In virulence test, the present isolate resulted in the development of clinical signs identical to those in naturally infected fish. The present results conclude that the present isolate is A. sobria and can be a pathogen which causes motile aeromonad septicemia to mud loach.
