In this paper, we propose a feature extraction method which extracts directional features of handwritten numerals by using the projection runlength. Our directional featrures are obtained from four directional images, each of which contains horizontal, vertical, right-diagonal and left-diagonal lines in entire numeral shape respectively. A conventional method which extracts directional features by using Kirsch masks generates edge-shaped double line directional images for four directions, whereas our method uses the projections and their runlengths for four directions to produces single line directional images for four directions. To obtain the directional projections for four directions from a numeral image, some preprocessing steps such as thinning and dilation are required, but the shapes of resultant directional lines are more similar to the numeral lines of input numerals. Four [$4{\times}4$] directional features of a numeral are obtained from four directional line images through a zoning method. By using a hybrid feature which is made by combining our feature with the conventional features of a mesh features, a kirsch directional feature and a concavity feature, higher recognition rates of the handwrittern numerals can be obtained. For recognition test with given features, we use a multi-layer perceptron neural network classifier which is trained with the back propagation algorithm. Through the experiments with the handwritten numeral database of Concordia University, we have achieved a recognition rate of 97.85%.

This paper proposes strategy development to improve the management of Multicultural Family Support Centers by analyzing four Multicultural Family Support Centers (MFSCs) in Chungcheongnam-do. The research was conducted from September 2012 to January 2013. Future directions for the four MFSCs are established based on a SWOT analysis on both the internal and external environments of the centers. Various strategic directions for the four MFSCs were identified based on these analyses. For center A (urban type, college contract type), the strategic directions included the specialization strategy, systemization strategy, empowerment strategy, standardization strategy, and achievement maximization strategy. The strategic directions for center B (urban-rural combined type, social welfare center contract type) included the improvement of multiculture awareness, specialization strategy, human resource development strategy, and networking strategy. For center C (farming and fishing community type, direct management type by local authority), the strategic directions included the specialization strategy, activation strategy, qualification strategy, and networking strategy. For center D (farming and fishing community type, social welfare center contract type), the strategic directions included the specialization strategy, business standardization strategy, human resource development strategy, and network expansion strategy. The suggested management strategy development for the four MFSCs can provide implications for the management of MFSCs in other areas in Korea.

The present study aims to increase the amount of surface flux by changing the magnetic directions of a spherical magnet (NdFeB) consisting of four poles. For this purpose, the magnetic directions of quartile spherical slices constituting the spherical magnet are manipulated and their three-dimensional analyses are carried out by using finite-element method via Maxwell environment. The analysis of the magnetic quartile spheres with four different magnetic directions are compared to the each other, and then the quartile sphere with the best surface flux distribution is suggested for rotor structure. It is clear emphasized that the induced torque of the spherical motor, in which such a rotor is used, will be improved as well.

Numbers structure reality and define the way people live. Both in Daoism and in Daesoon Jinrihoe they signify key concepts, notably the cardinal numbers from one through nine that classify different dimensions of the cosmos. Beyond these, the number twenty-four plays an important role. In a temporal mode, it marks the divisions or seasonal periods of the year. Consisting of fifteen days each, these periods signal (and are named after) changes in dominant weather patterns and the position of the sun. Generally activated in the body through particular seasonal activities and dietary prescriptions, in Daoism they are also the root of a series of healing exercises and certain refinement practices of internal alchemy. In Daesoon Jinrihoe, moreover, they are activated by chanting a specific incantation that invokes the twenty-four divine rulers of the divisions, originally a group of Tang Dynasty officials that in nature and function resemble the spirit generals of the early Celestial Masters. Beyond this, the number twenty-four also applies to space. Not unlike the twenty-eight lunar stations or mansions, traditional cosmology acknowledges twenty-four directions, made up of six constellations each in the four cardinal directions, complete with starry deities and divine generals. Their powers are activated with the help of written characters rather than vocal incantations, using techniques common both in Daoism and Daesoon Jinrihoe.

There are three things that are not known to the human being. That is when, where and how one will die. Most people live ignoring death. However, elements of death linger everywhere. The purpose of this treatise is investigates about justification Deciding for Other directions. First, I will investigate about Deciding for Other directions, when patient can not decide own, I will do investigate agent's decision's problem. Second, These four principles provide the common ground for biomedical ethics. Principlism argue that a method using four principles can resolve controversies in bioethics. The method holds that there are four principles-respect for autonomy, nonamleficence, beneficence, justice- that articulate the necessary conditions of common morality for health care and bioethics. Beauchamp and Childress respond by arguing that the two problems are nc the meaning or interpretation but the process of specification. Third, So, Supplement four principles' problem to Levinas concept of the Other theory. Levinas concept of the Other is very resemblant with 'Love your neighbour as yourself." Christians believe that Love is above all and they act accordingly. They base this faith mainly upon the motto of "love your neighbour as yourself." Fourth. difficult part of Levinas concept of the Other is that there is no human to equal infinite sense of responsibility. Can be supplemented about this through cooperation of community. Four principles can be brought to bear on moral choices. And they asserts that each principles has weigh but they do not assign a priority weighting of ranking. All the principles are equal in moral decision making.

Objectives: This paper reviews the integrated health promotion program in health center to analyse the problems and to provide the future directions aiming to health promotion block grants. Methods: The guidebook for the integrated health promotion program published by the Minister of Health and Welfare were reviewed in this study. And also the empirical results and theoretical considerations were used in making future directions. Results and Conclusion: This paper suggested four improvement directions as follows; first, the legal review committee is needed to approve when the central government change the way of health promotion program in health center. Second, the required programs should be replaced by an integrated outcom evaluation indicators. Third, the central government should strengthen the capacity of local government. And finally, visiting training should be conducted each health center.

Physical properties of artificial graphite electrodes were evaluated along three different directions; circumferential (X), radial (Y), and axial (Z) directions. Four kinds of commercial electrode products were used in this study for the evaluation; pole (AP) and nipple (AN) of manufacturer A, pole (BP) and nipple (BN) of manufacturer B. The mechanical, electrical, and thermal properties in X and Y directions were very similar to each other. In Z direction, however, the mechanical properties, including flexural strength and compressive strength, were higher, and electric resistance and thermal expansion were much lower than those in the other directions. The microstructures observed by optical microscope and scanning electron microscope revealed that the differences in properties by the measuring direction were caused by the preferential alignment of needle cokes along the Z direction. When comparing the properties of the electrode samples in the same direction, the mechanical properties mainly depended on the bulk density or porosity of the samples as well as preferential alignment of needle cokes.

1. Objectives The purpose of this study is to find the ground why constitution must be classified into 4 types. 2. Methods I analysed the basic presuppositions to class 4 Type Constitution in Sasang Constitutional Medicine(SCM). And I connected the presuppositions with other theories from the viewpoint of directional properties of human body. 3. Results and Conclusions The most important presupposition to class 4 Type Constitution and apply to clinical therapy in SCM is that there is native strength and weakness of lung's Exhale Dispersing Qi, liver's Inhale Gathering Qi, spleen's Ascending Yin Qi and kidney's Descending Yang Qi. If there is superior tendency of Qi flow direction in human body, 6 directions(upward, downward, forward, backward, outward and inward) will be remarkable. But, in embryonic period, the outer skin is originated from the back(ectoderm) and the alimentary canal is from the front(endoderm). Therefore 4 directions(upward, downward, outward and inward) will be more remarkable, and those directions are included in the former presupposition.

Objective: The author measured levels of fluoroscopic radiation exposure to the surgeon's body based on the different beam directions during kyphoplasty. Methods: This is an observational study. A series of 84 patients (96 vertebral bodies) were treated with kyphoplasty over one year. The patients were divided into four groups based on the horizontal and vertical directions of the X-Ray beams. We measured radiation exposure with the seven dosimetry badges which were worn by the surgeon in each group (total of 28 badges). Twenty-four procedures were measured in each group. Cumulative dose and dose rates were compared between groups. Results: Fluoroscopic radiation is received by the operator in real-time for approximately 50% (half) of the operation time. Thyroid protectors and lead aprons can block radiation almost completely. The largest dose was received in the chest irrespective of beam directions. The lowest level of radiation were received when X-ray tube was away from the surgeon and beneath the bed (dose rate of head, neck, chest, abdomen and knee: 0.2986, 0.2828, 0.9711, 0.8977, 0.8168 mSv, respectively). The radiation differences between each group were approximately 2.7-10 folds. Conclusion: When fluoroscopic guided-KP is performed, the X-Ray tube should be positioned on the opposite side of the operator and below the table, otherwise the received radiation to the surgeon's body would be 2.7-10 times higher than such condition.
