This study was conducted to evaluate extruded pellet (EP) diet compared with a raw fish moist pellet (MP) diet for flounder, Paralichthys olivaceus on field feeding experiments in Jeju area. The experimental EP diet (juvenile, growing and adult) was prepared based on the former studies on nutrient requirements and feed ingredient of flounder. Fish were distributed randomly to each aquarium as a group of 102,300 fish (initial mean weight 97 g) in field experimentⅠ and reared randomly to each aquarium as a group of 40,000 fish (initial mean weight 120 g) in field experimentⅡ. In field feeding experimentⅠ conducted in commercial flounder farm, survival, wt. gain (94-1,090 g), feed efficiency and condition factor of fish fed experimental EP were comparable to those of fish fed MP, but considerably higher protein efficiency ratio were observed in fish fed experimental EP. In field feeding experimentⅡ, no significant difference was observed in final mean weight of fish fed the experimental EP (1,234 g) and MP (1,286 g), and any noticeable problem caused by feeding the experimental EP was not found during the whole period of feeding trial. Survival of fish fed the experimental EP was lower than that of MP, and there was no significant difference in feed efficiency between the fish fed experimental EP and MP. Therefore, these results strongly suggest that diet EP could be developed to replace MP diet for the marketable size (1.3 kg) of production for flounder without adverse effects on growth performance. In particular, abdominal dropsy and reduction of condition factor, which are frequently occurred in commercial EP feeding farms, were not observed in flounder fed experimental EP.

The method regarding obtaining various kinds of attribute data of spatial information, including that of digital map, is normally restricted to Geographic survey that deals with in-field surveys. Geographic surveying for drawing digital map, however, require much effort due to the fact that a surveyor has to characterize geographic features individually in the field. Not only does the Geographic survey cover large area, but also its need for manual drawing and surveying using Draft map makes it more expensive and time-consuming. Though some recent Geographic surveys take advantage of MMS(Mobile Mapping System) to collect computerized information, there are inevitable limits in creating digital map with such data. This research will analyze the problems in current Geographic surveys and suggest adequate methods and standards for Geographic surveys by researching the methods of domestic/international service organizations that deal with establishing spatial information. This study therefore will aim to enhance the efficiency of creating digital map and Geographic survey, which would ultimately maximize the applicability of pan-national digital map by improving reliability of digital map and upgrading the utilizability of Geographic survey data.

This paper considers a fully coupled 3D BEM-FEM analysis for the ship structural hydroelasticity problem in waves. Fluid flows and structural responses are analyzed by using a 3D Rankine panel method and a 3D finite element method, respectively. The two methods are fully coupled in the time domain using a fixed-point iteration scheme, and a relaxation scheme is applied for improve convergence. In order to validate the developed method, numerical tests are carried out for a barge model. The computed natural frequency, motion responses, and time histories of stress are compared with the results of the beam-based hydroelasticity program, WISH-FLEX, which was thoroughly validated in previous studies. This study extends to a real-ship application, particularly the springing analysis for a 6500 TEU containership. Based on this study, it is found that the present method provides reliable solutions to the ship hydroelasticity problems.
Journal of Sasang Constitutional Medicine, 2013
In this study, the Sasang Constitutional diagnosis were carried out to Vietnamese subject living in Vietnam, and the external applicability of Sasang Constitutional Medicine was evaluated by analyzing the physiological symptoms and the pathological symptoms according to their constitutions. Methods Total 170 Vietnamese subjects who live in Hanoi were invited from Sep. 2012 to Jun. 2013 for the research, and subjects were diagnosed by 2 Sasang Constitution Medicine specialists. The collected data were analyzed in terms of the physiological symptoms and the pathological symptoms according to the Sasang Constitutions. Results There were significantly different in the physiological symptoms according to Sasang Constitutions, which were 'digest', 'perspiration', 'excrement', 'hot and cold', 'water' and in the pathological symptoms, which were 'sting pain in head' in Soyangin, 'back pain' in Soeumin, 'chest discomfort' in Taeeumin, 'skin discomfort' in Taeeumin, 'fatigue in the afternoon' in Soyangin, 'digestion' in Soeumin. Conclusions The Sasang Constitution Medicine which is a Korean traditional medicine is also applicable to foreign countries, and it can contribute to the health promotion.

This study is a comparative study of the social security system of Islamic countries in Asia-Indonesia, Malaysia, Iran, and Turkey. In particular, it seeks to understand the principles of zakāt and waqf used as a means of realizing economic justice to relieve the poor in Islamic communities, and how they currently operate as social security systems in Muslim countries.
