The purpose of this research is to analyze content elements of Housing area in 2013 middle school Technology Home Economics textbooks 1 and 2, total of 22 according to 2009 revised curriculum. The analysis method was content analysis, focusing on contents of main text, tables & figures, reading material, and activity materials by their content elements. This research will contribute in obtaining suggestion for the post curriculum/textbook development and helping teachers to perform a lesson. The results are as follows. First, Housing area included 1 to 4 content elements per each units, from 2 chapters and 6 units. The content elements stated in Home economics curriculum were total of 16 which consists of 'the meaning of housing,' 'housing types,' 'family forms,' 'family life style cycle,' 'life style,' 'neighboring environment,' 'co-living values,' 'air environment,' 'heat environment,' 'light environment,' 'acoustic environment,' 'space division,' 'circulation', 'effective use of space,' and 'sustainable dwelling practice.' All of these components are dealt with in every textbooks. Second, the numbers of content elements provided in each textbooks were the same, however they showed difference in their contextual aspect. Some contents need supplemental material for their lacking content element. Others need proper understanding of the concept because some showed different contents from the appropriate content elements. Third, repetitions in content elements were observed, the contents of 'co-living values' in textbook 1 and 'sustainable dwelling practice' in textbook 2 were similar in terms of eco-friendly housing, co-housing and universal housing. These two content elements should be merged as one next curriculum, or should be stated together in one subunit.

An eddy-resolving free-surface primitive-equation model with nonlinear terrain-following coordinates is established to study the exchange of water masses among the Asian marginal seas and their adjacent waters. A curvilinear coordinate system is used to generate the horizontal grid with a variable resolution for the regional oceans from $5^{\circ}$S to $45^{\circ}$N and $100^{\circ}$E to $155^{\circ}$E. The higher resolution region has about a 10 km by 10 km grid covering the complex geometry of the coastal marginal seas, while the lower resolution region has about a 30 km by 30 km grid covering the eastern Pacific. The model is initialized by the Levitus annual climitology and forced by the monthly mean air-sea fluxes of momentum, heat, and freshwater derived from the Comprehensive Ocean-Atmosphere Data Set. High-resolution and low-viscosity are identified as the key factors for a better representation of the exchange of waters through narrow straits and passages between the marginal seas and their adjacent waters. The dynamics of the loop currents and eddies in the South China Sea and Celebes Sea are examined in detail. It has found that the anticyclonic loop and detached eddies from the Kuroshio through the Luzon Strait play an important role in transporting warm and salty water into the South China Sea, while the cyclonic circulation of the Mindanao Current in the Celebes Sea plays a role in contributing cold water to the Indonesian throughflow. The deep undercurrent of the western Pacific is shown to provide fresher water to the South China Sea and Celebes Sea. These modeling results suggest that the exchange processes via the narrow straits and passages are of fundamental importance to the maintenance of water masses for the marginal sea region.

Fragrance(aroma) have many effects on body. Recently, aromatherapy was used to treat dementia, atopicdermatitis, alopecia areata, perineal disease, lymphatichydrops, and articularrheumatism. And people are interested in physical and mental effects of aroma, especially in mental. People empirically have been known the effects of aroma on soul and used aroma in life from long ago. They have had a meditation and had a sacrificial rites burning incense. Scholars also burned incense when reading books or tasting tea. Until now, there is no physiological study about recognition process and effects of aroma on body, but only many clinical studies using aromatherapy. Fragrance(aroma) is different from smell and good flavors of herbs. And it goes through nose and has effects on body in harmony on So-mun(素問). Also flavors of herbs are spreaded ki of herbs and have many effects on body. Aroma coming through the nose is recognized by co-operation of five-viscera(五臟), especially heart and lung. The nose and pectoral qi(宗氣) are related with lung. The lung opens into the nose, reflect its physiological and pathological conditions. Pectoral qi(宗氣) is the combination of the essential qi derived from food with the air inhaled, stored in the chest, and serving as the dynamic force of blood circulation, respiration, voice, and bodily movements. Because of the heart-spirit(心神), Heart is the organ can recognize the aroma, although the nose is the first organ of receiving aroma. Five spirits(五神: ethereal soul(魂), spirit(神), ideation(意), corporeal soul(魄), will(志)) and seven emotions(七情: joy(喜), anger(怒), anxiety(憂), thought(思), sorrow(悲), fear(恐), fright(驚)) are rerated with five-viscera(五臟) and essence-spirit (精神) processing steps and express of emotions. And aroma effects on five-viscera(五臟). So aroma have many effects on body, especially mentally.

The evolutionary process of the polar low, which caused the heavy snowfall in the East Coast area on 11~12 February 2011, was investigated to describe in detail using synoptic weather charts, satellite imageries, and ERA (European Centre for Medium-Range Weather Forecasts Re-Analysis) -Interim reanalysis data. It was revealed that 1) the polar low was generated over the sea near Busan where a large cyclonic shear in the inverted trough branched from the parent low existed, 2) during the developing and mature stages, there was a convectively unstable region in the lower layer around the polar low and its south side, 3) the polar low was developed in the region where the static stability in the 500~850 hPa layer was the lowest, 4) the result from the budget analysis of the vorticity equation indicated that the increase in the vorticity at the lower atmosphere, where the polar low was located, was dominated mainly by the stretching term, 5) the warm core structure of the polar low was identified in the surface-700 hPa layer during the mature stage, 6) there was a close inverse relationship between a development of the polar low and the height of the dynamic tropopause over the polar low, and 7) for generation and development of the polar low, large-scale circulation systems, such as upper cold low and its combined short wave trough, major low (parent low), and polar air outbreak, should be presented, indicating that the polar low has the nature of the baroclinic disturbance.

This study is for the Kyungduk-Dan(as a altar of Milsung-Daegun) and The Manun-Jae the characteristics(lay out and planning, window patterns, structure, materials) of the the Korean traditional house during the modern era. Before Manun-Jae was used for the house. The Kyungduck-Dan was constructed in August according to the Lunar Calender in 1927. The Manun-Jae(house for Ki-hun Kang, millionaire ) was completed in 1924. Modern Architectures brought to Korea with the bricks, the tiles, the flash doors, the plate grasses, the brass hardwares. These architectural material was used in positive. During the construction of Manun-Jae in 1924, it happened the architectural exchage among a korean, a chinese and a japanese constructor. Though using the air exhaust valve at the kitchen of Ukyung-Kak( old Anchae), it could be assume that the modern convenience and the improvement of residential environments was considered at that period during the construction of Manun-Jae. That construction was elected with the brick($222mm{\times}106mm{\times}50mm$), the chinese colored tile and plate glass such a modem materials. The new shape of the korean lattice window and the wooden flash-door with glass was used. In Ukyung-Kak, the Chan-Maru(service space) and the kitchen such as a service space or concise utility zone was organically connected. Especially, considered the domesitic activity and circulation, the western kitchen sink and the Chan-Maru(service space) was rationally placed. At the Manun-Jae and the Kyungduck-Dan, the architectural characteristic is that the new shape of windows was used. The lattice window at the Ondol room of Ukyung-Kak, was rgadually added the plate glass and the wood plate. The lattice window with the grid shape at kitchen of that building was adapted japanese grid lattice window in korea at that period. It is the sample that korean traditional house was typically influenced from the japanese resident culture. The Manun-Jae and the Kyungduck-Dan as the modern house kept the form of korean traditional architecture, and was partially adapted a modern characteristic space and modern architectural materials. During the japanese occupancy, these residence can be showed the transition in formally.

The onset time of sea breeze at Haeundae is faster than that at Suyoung in spite of the observation site at Suyoung being 5m and that of Haeundae being 1 km away from the coastline. We therefore simulate the effects of terrain on the onset time of sea breeze at Suyoung and Haeundae districts by using the LCM(Local Circulation Model). This phenomenon is due to the nighttime density flow, which is created by nighttime radiative cooling. It follows the slope of the highlands surrounding the urban area, gathers at a central area of Busan, and then flows out to a lower area like Suyoung river. This process continues after sunrise. In researching the AWS wind speed, we find an important thing. That is to say, the nighttime mean wind speed at Suyoung is three times greater than that at Haeundae. This property shows that Suyoung is an outflow channel of nighttime air mass. The above observed data shows that terrain effect has a important role on the onset of sea breeze.

The following results obtained through studies related on nose. 1. Nose is called mingtang(明堂) mianwang(面王), as it emphasize the meaning of viewing diagnosis(望診) and is called yuanpinzhimen(元牝之門), tianpinzhimen(天牝之門), qiqizhimen(七氣之門) as it emphasize the meaning of the entrance of atmosphere flow. Because it's position is the middle of face, we call tianzhongzhiyue(天中之嶽), zhongyue(中嶽). 2. As the organ of body, nose comes under the category of lung-iron(肺金), functionally comes under the category of heart-fire(心火). Functionally we can smell oder, organically nose is the pathway of respiration and to be resonator. 3. Wuzangliufu(五臟六腑) is arranged closely around the nose. The essence of wuzangliufu(五臟六腑) reflect nose, so nose becomes the standard of coloring diagnosis(色診). 4. We call nose is feihou(肺候), but it is not connected directly between the lung channel and nose. In case of lung symptom(肺證), first of all, nose become to appear the condition of lung, the lung channel and nose is close functionally. 5. The view of channels, nose is a connection with channels of yangming(陽明), bladder(膀胱), du(督脈) directly. By the connecting of each three channels, spleen stomach heart and kidney(脾胃心腎) are connected with indirectly. As the result of the relation, nose helps for body to breathe and to circulate qi(氣) and smell. And so the nature of wuzangliufu(五臟六腑) appear to the nose. 6. Particularly, the yangming channel(陽明經), and the bladder channel(膀胱經) are important. Because air-qi(天氣) reach to kidney lung through nose, ground-qi(地氣) reach to spleen stomach through mouth and yingwei(營衛) revolve through the bladder channel(膀胱經). As the result nose becomes the essential organ of circulation of yinewei(營衛), ascent and descent of qi(氣).

A full-sized model for the horizontally oriented metal cask containing 21 spent fuel assemblies has been considered to evaluate the internal natural convection behavior within a dry shield canister (DSC) filled with helium as a working fluid. A variety of two-dimensional CFD numerical investigations using a turbulent model have been performed to evaluate the heat transfer characteristics and the velocity distribution of natural convection inside the canister. The present numerical solutions for a range of Rayleigh number values ($3{\times}10^6{\sim}3{\times}10^7$) and a working fluid of air are further validated by comparing with the experimental data from previous work, and they agreed well with the experimental results. The predicted temperature field has indicated that the peak temperature is located in the second basket from the top along the vertical center line by effects of the natural convection. As the Rayleigh number increases, the convective heat transfer is dominant and the heat transfer due to the local circulation becomes stronger. The heat transfer characteristics show that the Nusselt numbers corresponding to $1.5{\times}10^6$ < Ra < $1.0{\times}10^7$ are proportional to 0.5 power of the Rayleigh number, while the Nusselt numbers for $1.0{\times}10^7$ < Ra < $8.0{\times}10^7$ are proportional to 0.27 power of the Rayleigh number. These results agreed well with the trends of the experimental data for Ra > $1.0{\times}10^7$.

This study examined the structural elements of Korean-style houses (Hanok) and proposed formula accounting for their similar patterns and regular behavior. The design of modern apartment buildings adopts many aesthetic elements from Hanok but those are only for interior decoration. In this study, the projected Hanok eaves were examined in terms of the length of solar insolation. Leaning pillars toward the inside of the building were analyzed in detail not only for the front and back pillar, side pillar, but also the corner pillar. This study also suggested a design element from the Hanok structure, such as the elevated balcony, porch flooring, and inner garden in porch area. In addition, the new apartment plan improved air circulation, ventilation and natural lighting.

With the negative influences and damage from Asian dust increasing, it's getting important to investigate the climate and soil condition of the source region of Asian dust. There is a high possibility that the desertification and the drastic decrease of plants in China and Mongolia make worse the situation (bad effects of Asian Dust). To detect the movement of Asian dust caused by air circulation, we need to watch the state of the source region to get useful information for the prevention of the dust pollution, and to predict what part of China will become the source region. Therefore, using TOMS aerosol index data, NCEP reanalysis data that is Remote Sensing data from 1981 to 2000 (except 1993~1996, 4 years), for 16 years, examined the relation between the dust occurrence and weather elements. Dust occurrence appeared much in spring season from March to May in study areas. It had a dry climate during that season as follows : relative humidity about 20~40%, temperature about -5~5$^{\circ}C$, precipitation about 33-180 mm, wind speed about 4-10 ms-1. Dust occurrence and weather element annual change in study areas decreased gradually till 1990, but in Gobi desert the incidence of dust occurrence increased since 1997. As a result, found out that the more the precipitation, the less dust occurrence, because the precipitation and surface wind speed had a direct influence on the soil of the source region of dust.
