In Korean education, the health contents are scattered in various course subjects throughtout the primary and junior high school curriculum. So it is very difficult to provide systematic health education. The purpose of this study was to provide a guide for health education using health topic areas and major concepts that represent the scope of material that should be covered in health instruction. The steps used in selecting these health topic areas and major concepts were as follows: 1. A review of the literature related to health and health education was done to develop the rationale underlying this study. 2. Health topic areas basic to the growth and development characteristics of children, to human needs and to societal needs for healthful living were indentified. 3. The major concepts for each health topic area based on health sciences and children's growth and development levels were selected. 4. The major concepts selected were organized in sequence to guide health education from grade one to grade nine. The results of this study were as follows: 1. The identification of eleven health topic areas essential for health education. These include: personal habits and health healthy growth and development nutrition and health prevention of disease and disorders drugs and health mental health family life and health sex education accident prevention consumer health community health 2. The identification of the major concepts(generalizations) for each health topic area: 33 major concepts were identified as a guide in determining the health content of health education programs. These are 1) body cleaniness, 2) health of the sensory organs, 3) dental health, 4) exercise and rest, 5) growth and development, 6) body structure and function, 7) developmental tasks, 8) balanced nutrition, 9) eating habits, 10) food preparation and food storage, 11) sources of disease and disorders, 12) disease preventive behavior, 13) care during illness, 14) drug use and misuse, 15) drug addiction, 16) emotional responses, 17) human relationship, 18) self concept, 19) social adjustment, 20) health habits of the family, 21) interdependence of family members, 22) origin of life, 23) characteristics of man and woman, 24) sexual instinct, 25) safety behavior, 26) emergency measures, 27) criteria for selection of health products, 28) proper use of health information, 29) utilization of health and medical services, 30) environmental conservation, 31) environmental pollution, 32) population control, 33) function of public health services. 3.

The costume style of the Chosun dynasty changed greatly after Imjinwaeran (the Japanese Invasion of Chosun Korea, 1592∼1598). Most of the extant costumes come from the late Chosun, but some costumes produced be-fore Imjinwaeran have been excavated, and in addition, information on these older constumes is contained in contemporary literature. Of especial value in the study of pre-Imjinwaeran Chosun constumes is a mid-sixteenth century palace painting depicting the worship of Buddha, a painting in the collection of the Ho-Am Art Museum in Seoul. The present study of costume during the middle Chosun dynasty focuses on this painting, and compares it with other contemporary palace paintings, and with other contemporary palace paintings, and with Nectar Ritual Paintings. The following conclusion were drawn : * Concerning woman's hair styles of the time, married women wore a large wig. Un-married women braided their hair, and then either let it fall down their back or wore it coiled on top of their head. * The major characteristic of woman's costumes was a ample, tube-like silhouette, with the ratio of the Jeogori(Korean woman's jacket) and skirt being one-to-one. * The style of Jeogori in the painting was like that of excavated remains. Some Jeogoris were simple (without decoration), while some Jeogoris were worn with red sashes. Here we can confirm the continuity of ancient Korean costumes with those of the sixteenth century * Although the skirt covered the ankles, it did not touch the ground. Because the breadth of the skirt was not wide, it seems to have been for ordinary use. Colors of skirts were mainly white or light blue. * All men in the painting wore a headdress. Ordinary men, not Buddhist monks, wore Bok-du (headstring), Chorip (straw hat), or Heuk-rip (black hat). In this painting, men wore a Heukrip which had a round Mojeong (crown). * The men wore sashes fastened around their waist to close their coats, which was different from the late Chosun, in which men bound their sashes around their chest. That gave a ration of the bodice of the coat to the length of the skirt of one-to-one, which was consistent with that of woman's clothing. * In this painting, we cannot see the Buddhist monk's headdress that appeared later in the Chosun, such as Gokkal (peaked hat), Songnak (nun's hat), and Gamtu (horsehair cap). These kinds of headdresses, which appeared in paintings from the seventeenth century, were worn widely inside or outside the home. Buddhist monks wore a light blue long coat, called Jangsam (Buddhist monk's robe) and wore Gasa (Buddhist monk's cope), a kind of ceremonial wrap, round their body. We can see that the Gasa was very splendid in the early years of the Chosun dynasty, a continuing tradition of Buddhist monk's costumes from the Koryo dynasty.

Since the Arab spring in 2010, SNS prompted discussions about the roles to organize collective actions. First of all, mobile media and SNS help to mobilize both on and offline social movement, second, to create new forms of collective actions, third, to organize social movement organizations across the world, fourth, to empower movement participants to develop new collective identities. On the other hand, the same technologies also hinder social movements from developing continuity and dedication. In addition, the problems of digital divide might aggravate the divisive process to organize collective actions across the world. This research is built on these ongoing arguments about the potentials and limitations of new media technologies. In particular, this research tries to move beyond the confrontational approaches to the media through the case study of Save The Jeju Island social movements on Facebook. The movement SNS on Facebook aims to provide as well as organize international SMOs and activists that might help deeper understandings on the potentials and limitations of online communication strategies for global social movements.

In this paper, in order to derive the two-dimensional field effect of n-InAlAs/InGaAs HEMTs, we suggested analytical model by solving the two-dimensional Poisson's equation in both InAlAs and InGaAs regions by taking into account the longitudinal field variation, field-dependent mobility, and the continuity condition of the channel current flowing within the quantum well shaped channel. Derived expressions for long and short channel devices would be applicable to the entire operating regions in a unified manner. Simulation results show that the drain saturation current increases and the threshold voltage decreases as drain voltage increases. Compared with the conventional model, the present model may offer more reasonable explanation for the drain-induced threshold voltage roll-off, the Early effect, and the channel length modulation effect. Furthermore, it is expected that the proposed model would provide more reasonable theoretical basis for analyzing various long and short channel InAlAs/InGaAs HEMT devices.

This study was carried out with an objective to prepare the framework of conformity for the 21st century modern fashion, which is interactive with mankind, based on a position that the 21st century contemporary fashion with its amalgamating trend of diversified artistic forms may not be elucidated on a standpoint centering on one certain modality. The hybrid fashion trend of historical modality which provides freedom and satisfaction in creation of an individuals expressive power in expressing true desire of mans inside through man-centered thought of the times has made multifarious motives of the past and present fragmentary. It thus extracts inner divisions and the concept of consolidation through three-dimensional form. Modern fashion is newly interpreted by the material and details of high technologies. and is harmonized by mix and match with various expressions. By having it, it is being expressed together with many types of dresses and ornaments. Modern fashion is being expressed together with many types of dresses and ornaments by new interpretations with the material and details of high technologies and by being harmonized with mix and match with various expressions. The hybrid fashion design trend of regional elements formed by stimuli and contacts of diverse local culture by globalization of network that was achieved by scientific technologies of the contemporary information society has disintegrated varied boundaries in the conventional culture by the latest communication technology-new media on the basis of newly created culture. The fact that regional elements could be expressed as if they were interrelated without each being deprived of originality may be explained with an interpretation on pluralism. The hybrid fashion design trend of cultural aspect, which manifests in the background of scientific technological culture as it transcends the societal-cultural boundaries based on the de-centralization theory of Frederic Jameson, has supplemented the imperfect meanings through conversional correlation with other forms and internal program changes. The middle stratal and polyhedral characteristics are seen as each cultural element is dismantled and reassembled by application of 'multiple-time point expression'. Design forming method is not to bring destruction from outside, but to embrace instability and chaos through radical dismantling of the inside. and to pursue diversity and openness. Thus. it is implemented by an approach that takes the role of design process. In communication of discontinuity, continuity was dismantled through forms of mixing, overlap, perversion, insertion and coincidence.

A drop structure, one of the representative river-crossing structures, is constructed to stabilize a riverbed. On the other hand, the structure interrupts the continuity of the river and causes the destruction of the hydro-ecological environment. Therefore, laboratory experiments of a natural type of drop structure with low differences were performed, and the empirical formula of a local scour hole is proposed. Four experimental flow rates were tested for various types of the drop structure models with 28 test cases. Based on the scour test, it was confirmed that the maximum scour depth occurs rather than the result of applying the previously proposed scour depth formulae. Correlation analysis of the major factors of scour hole at the downstream of the drop structure revealed a strong correlation between the upstream flow characteristics, drop structure height, and total crossing length of the drop model. In addition, the depth and length estimation formula of the maximum scour hole were proposed using the dimensionless variables and validated. In the future, it is also expected that more accurate scour prediction and calculation can be derived by conducting experimental studies and numerical analysis considering the various bed materials and flow conditions.

In the satellite remote sensing, the operational environment of the satellite sensor causes image degradation during the image acquisition. The degradation results in noise and blurring which badly affect identification and extraction of useful information in image data. Especially, the degradation gives bad influence in the analysis of images collected over the scene with complicate surface structure such as urban area. This study proposes a multi-stage image restoration to improve the accuracy of detailed analysis for the images collected over the complicate scene. The proposed method assumes a Gaussian additive noise, Markov random field of spatial continuity, and blurring proportional to the distance between the pixels. Point-Jacobian Iteration Maximum A Posteriori (PJI-MAP) estimation is employed to restore a degraded image. The multi-stage process includes the image segmentation performing region merging after pixel-linking. A dissimilarity coefficient combining homogeneity and contrast is proposed for image segmentation. In this study, the proposed method was quantitatively evaluated using simulation data and was also applied to the two panchromatic images of super-high resolution: Dubaisat-2 data of 1m resolution from LA, USA and KOMPSAT3 data of 0.7 m resolution from Daejeon in the Korean peninsula. The experimental results imply that it can improve analytical accuracy in the application of remote sensing high resolution panchromatic imagery.

Base researches in geoscience and mineral resources, such as geological and geo-thematic mapping, geological survey and observation, have long-term, continuity and time-leasing characteristics and they are difficult to present the particular research stages or progressions in the research span. The Technology Readiness Levels (TRLs), developed by the U.S. National Aeronautics and Space Administration (NASA), is effective for presenting research maturity levels and progression in the development of new technologies. This study suggests adjusted definitions for the Technology Readiness Levels to fit Geo-technology (Technology in Geoscience and Mineral Resources). Base geological researches, including mapping, surveys and observation, can be also presented in research levels from TRL 1 (R&D planning, literature survey) to TRL 9 (geological information construction and service in all target areas) in terms of the final product's coverage. Moreover, not only development and construction of commercial products, geological disasters and environmental researches can also be presented in field demonstrations through public pilot applications. The modified commercialization or cemonstration TRLs in Geo-technology are TRL 5 (starting pilot field application), TRL 6 (pilot field operation) and TRL 7 (pilot field operation for a larger scale, greater than ten percent of the actual environment).

The effects of carrier transport and input power on the extinction ratio was theoretically analyzed in a 1.55${\mu}m$ InGaAsP/InGaAsP multiple-quantum-well(MQW) electroabsorption(EA) modulator. Poisson's equation, current continuity equations for electrons and holes, and optical field distribution were self-consistently solved by considering electric field dependent absorption coefficients. The field screening effect due to the carrier accumulation in heterointerface and the space-charge region occurred more seriously at the input side of modulator as input optical intensity increased. It was revealed that extinction ratio could be steeply degraded for modulator with the length of 200${\mu}m$ when an input power exceeds 10mW. A degradation of extinction ratio due to the field screening effect would be more significantly at high-performance devices such as a 1.55${\mu}m$DFB-LD/EA-modulator integrated source where optical coupling efficiency is almost complete or a very high-speed modulator with its length as short as a few tens ${\mu}m$.

In this paper, we propose a QoS-based handover management scheme in SDN. Even though there have been lots of recent services such as IoT, the conventional networks provide a monolitic handover method without considerations on flow-specific QoS features. For example, the conventional Internet provides a handover method which only considers IP continuity. On the other hand, 4G and 5G networks use a strict handover method for all kinds of flows with resource reservations. This means that it is difficult to guarantee the QoS requirements for the flow with a strict QoS requirement in Internet and the inefficient resource utilization can occur in the 4G and 5G because of the strict QoS-based handover management. The proposed scheme proposes the flow handover management scheme based on QoS requirements according to the SDN controller's management. From the network operators' perspective, the proposed scheme can provide the efficient resource utilization as well as QoS provisioning.
