Objectives : Through a comparative study between Sasang constitutional medicine and Syndrome identification and treatment medicine about the theory of diagnosis, the theory of herbal medicine, the theory of prescription, the theory of acupuncture and constitutional medicine to put forward a complementary perfect solution which has good clinical utility. Methods : We compared and sorted out the textbook of Korean Sasang constitutional medicine which named Sasang medicine, and also the textbook of Chinese TCM which was including Basic theory of TCM, Diagnostics of TCM, Science of Chinese materia medica, Pharmacology of traditional Chinese medical formulae, Science of acupuncture and moxibustion, Constitution of TCM, and also related papers. Results : (1) Through a comparative study between Sasang constitutional medicine and Syndrome identification and treatment medicine about diagnosis, herbal medicine, prescription and acupuncture, Sasang constitutional medicine is a medical system which gives priority to balance of organs, when Syndrome identification and treatment medicine is a medical system that gives priority to improve symptom. (2) The prescriptions of Sasang constitutional medicine are used for the treatment of basic pathogenesis in the chronic stage of the disease, which can recover vital qi, when Syndrome identification and treatment medicine are used for the treatment of stage pathogenesis in the acute stage of the disease, which can get rid of pathogenic factors. (3) There are two kind of complementary perfect solution between Sasang constitutional medicine and Syndrome identification and treatment medicine. One perfect complementary medicine is that Sasang constitutional medicine plays a major role when Syndrome identification and treatment medicine plays a supporting role. The other one is that Syndrome identification and treatment medicine plays a major role when Sasang constitutional medicine plays a supporting role. It determined by the usual symptoms and the symptoms now, vital qi and pathogenic factors, symptom and the root cause, acute stage and chronic stage, and the state of pathogenesis. Conclusion : A new perfect complementary medicine can be created which is based on the setting that Sasang constitutional medicine primarily treat the usual symptoms, vital qi, the root cause, chronic stage and basic pathogenesis when Syndrome identification and treatment medicine primarily treat the symptoms now, pathogenic factors, symptom, acute stage and stage pathogenesis.

This study identified problems of the existing ecosystem-based fisheries assessment approach, and suggested new methods for scoring risk and for the estimation of fishery risk index. First, risk scores of zero to two for target and limit reference points for each indicator were replaced by those of zero to three, and the risk scores were calculated from new formulae which were developed in this study. Second, a new method for estimating fishery risk index (FRI) was developed in this study, considering the level of indicators. New method was applied to the Korean large purse seine fishery, large pair trawl fishery and drag net fishery. More precise and detailed risk scores were obtained from the new method, which can explain the risks by the wider range of both risk levels for 'better than target' and 'beyond limit'. The new method for estimating FRI could avoid the basic problem related with duplicated computations of fishery-level indicators, which improved the estimated FRI to be more accurate. Also, a method for estimating variance of FRI using the bootstrap was proposed in this study.

This paper proposes an adaptive moving average (A-MA) control chart with variable sampling intervals (VSI) for detecting shifts in the process mean. The basic idea of the VSI A-MA chart is to adjust sampling intervals as well as to accumulate previous samples selectively in order to increase the sensitivity. The VSI A-MA chart employs a threshold limit to determine whether or not to increase sampling rate as well as to accumulate previous samples. If a standardized control statistic falls outside the threshold limit, the next sample is taken with higher sampling rate and is accumulated to calculate the next control statistic. If the control statistic falls within the threshold limit, the next sample is taken with lower sampling rate and only the sample is used to get the control statistic. The VSI A-MA chart produces an 'out-of-control' signal either when any control statistic falls outside the control limit or when L-consecutive control statistics fall outside the threshold limit. The control length L is introduced to prevent small mean shifts from being undetected for a long period. A Markov chain model is employed to investigate the VSI A-MA sampling process. Formulae related to the steady state average time-to signal (ATS) for an in-control state and out-of-control state are derived in closed forms. A statistical design procedure for the VSI A-MA chart is proposed. Comparative studies show that the proposed VSI A-MA chart is uniformly superior to the adaptive Cumulative sum (CUSUM) chart and to the Exponentially Weighted Moving Average (EWMA) chart, and is comparable to the variable sampling size (VSS) VSI EWMA chart with respect to the ATS performance.

This paper proposes a selectively cumulative sum (S-CUSUM) control chart with variable sampling intervals (VSI) for detecting shifts in the process mean. The basic idea of the VSI S-CUSUM chart is to adjust sampling intervals and to accumulate previous samples selectively in order to increase the sensitivity. The VSI S-CUSUM chart employs a threshold limit to determine whether to increase sampling rate as well as to accumulate previous samples or not. If a standardized control statistic falls outside the threshold limit, the next sample is taken with higher sampling rate and is accumulated to calculate the next control statistic. If the control statistic falls within the threshold limit, the next sample is taken with lower sampling rate and only the sample is used to get the control statistic. The VSI S-CUSUM chart produces an 'out-of-control' signal either when any control statistic falls outside the control limit or when L-consecutive control statistics fall outside the threshold limit. The number L is a decision variable and is called a 'control length'. A Markov chain model is employed to describe the VSI S-CUSUM sampling process. Some useful formulae related to the steady state average time-to signal (ATS) for an in-control state and out-of-control state are derived in closed forms. A statistical design procedure for the VSI S-CUSUM chart is proposed. Comparative studies show that the proposed VSI S-CUSUM chart is uniformly superior to the VSI CUSUM chart or to the Exponentially Weighted Moving Average (EWMA) chart with respect to the ATS performance.

Though the Hough transform is a well-known method for detecting analytical shape represented by a number of free parameters, the basic property of the Hough transform, the one-to-many mapping from an image space to a Hough space, causes the innate problem, the sensitivity to noise. To remedy this problem, Edge Strength Hough Transform (ESHT) was proposed and proved to reduce the noise sensitivity. However the performance of ESHT depends on the size of a Hough space and image and some other parameters, which play an important role in ESHT and should be decided experimentally. In this paper, we derived a formula to decide decreasing parameter. Using the derived formulae, the decreasing parameter value can be decided only with the pre-determined values, the size of a Hough space and an image, which make it possible to decide them automatically.

Battles between players and monsters are considered to be the core issues of RPG games, and they are something that effects the players the most when it comes to thinking whether that particular game is fun or not. Even though MMORPGs have enabled RPGs to get out of the repetitiveness into unlimited possibility of expandability and capability of modification of game plays, essential game play process remains still important - the basic battle between the player and the monsters. In this research, we made a simulator to simulate the process of the battles to estimate results of battles by pre-testing the battles with setting up the experience values of players and monsters using formulae needed for the battle systems at the beginning of game development. It can be utilized at a tester to find out a better configuration of monsters in the maps for better optimization of time and efficiency of the battles to satisfy the game planning.

Several in-situ testing methods of adhesively bonded joints under static short-time tensile loading are critically analyzed in terms of experimental procedure and data evaluation. Due to its rather homogeneous stress state across the glue line, the tensile-shear test with thick single-lap specimens, according to ISO 11003-2, has become the most important test process for the determination of realistic materials parameters. This basic method, which was improved in both, the experimental part by stepped adherends and easily attachable extensometers and the evaluation procedure by numeric substrate deformation correction and test simulation based on the finite element method (FEM), is therefore demonstrated by application to several kinds of adhesives and metallic adherends. Multi-axial load decreases the strength of a joint. This effect, which is illustrated by an experimental comparison, impedes the derivation of realistic mechanical characteristics from measured force-displacement curves. It is shown by numeric modeling that tensile-shear tests with thin plate substrates according to ISO 4587, which are widely used for quick industrial quality assurance, reveal an inhomogeneous stress state, especially because of relatively large adherend deformation. Complete experimental determination of the elastic properties of bonded joints requires independent measurement of at least two characteristics. As the thick-adherend tensile-shear test directly yields the shear modulus, the tensile butt-joint test according to ISO 6922 represents the most obvious complement of the test programme. Thus, validity of analytical correction formulae proposed in literature for the derivation of realistic materials characteristics is verified by numeric simulation. Moreover, the influence of the substrate deformation is examined and a FEM correction method introduced.

U-flanged truss beam is composed of u-shaped upper steel flange, lower steel plate of 8mm or more thickness, and connecting lattice bars. Upper flange and lower plate are connected by the diagonal lattice bars welded on the upper and lower sides. In this study the structural experiments on the U-flanged truss beams with various shapes of upper flange were performed, and the flexural and shear capacities of U-flanged truss beam in the construction stage were evaluated. The principal test parameters were the shape of upper flange and the alignment space of diagonal lattice bars. In all the test specimens, the peak loads were determined by the buckling of lattice bar regardless of the upper flange shape. The test results have shown that the buckling of lattice bar is very important design factor and there is no need to reinforce the basic u-shaped upper flange. However, the early lattice buckling occurred in the truss beam with upper steel bars because of the insufficient strength and stiffness of upper chord, and the reinforcement in the upper chord is necessary. The formulae of Eurocode 3 (2005) have presented more exact evaluations of lattice buckling load than those of KBC 2016.

This study is to analyze works of Memphis design in the 1980s, which captured the appearance of a diversified society since the 20th century, and to present practical designs that can communicate with the public through the formulation of indoor lighting. As a research method, the background of the occurrence of Memphis groups, the theoretical background and the formative features of Memphis designs are considered around literature and prior research. The research applied Memphis's formative characteristics, colors and patterns to incorporate newly formulated designs into lighting. Lighting lamps in the forms that have made small changes to basic shapes show not only its functionality and decorability, but also its scalability as a formative language that conveys the emotions contained within humans. In addition, the choice of materials according to the changes in sculpture in the production of the work will suggest the possibility of creating a new formative art.
