본 연구에서는 한국고용정보원의 청년패널조사(YP2007) 4-14차(2010~2020년) 자료를 이용하여 청년층의 주거 관련 특성 현황들을 정리해보고, 심층적으로 주거의 특성들(자가 여부, 아파트 거주 여부)에 미치는 영향요인을 추정하였다. 분석 결과, 남성, 고학력층, 취업한 청년층은 자가 및 아파트에 거주할 가능성이 높지만, 이들 중 상당수는 부모와 동거중인 것으로 보인다. 반면, 경제적으로 독립한 청년층의 경우, 전/월세 형태의 입주형태와 다세대, 빌라, 오피스텔 등의 주택에 거주하는 경우가 많은 것으로 추정된다. 청년층이 주거, 일자리, 결혼 등의 문제로부터 벗어나 제 역할을 할 수 있는 여건을 마련하기 위해서는 주택 마련 및 임대 등에 소요되는 비용이 청년층의 경제적 상황과 수준 등에 맞게 맞추어져야 하겠다.

Feng Shui practice is very popular in East Asia and has been rapidly adopted by the population of the West. As Feng Shui involves knowledge of object placement, it opens opportunities to market Feng Shui knowledge and products. This paper presents an analysis of a successful Feng Shui enterprise, World of Feng Shui (WOFS), that has been established by a well-known Feng Shui expert Lillian Too and her daughter Jennifer Too. The enterprise's marketing strategies and tactics are tied to the theoretical concept of social influence, widely researched in the consumer behavior literature. The three types of social influence (informational, utilitarian, and value-expressive) are examined in relation to WOFS' marketing strategies using secondary data material. The main results indicate that the strategies of WOFS enterprise address all three types of social influence. The articles generated on-and off-line can be mostly associated with the informational influence. The off- line activities such as events, courses/workshops, and TV shows are also informational in nature. The Q & A sections/postings can be considered as representative of the utilitarian influence. They give experts (e.g., Lillian Too) the opportunity to provide individuals with problem-specific recommendations. Mega-mall website provides the value-expressive influence as purchase and consumption of the Feng Shui products is most susceptible to this type of influence. In terms of implications, WOFS enterprise strategies are suitable not only for consumes but also for business executives in Asia and in the West as architects, designers, and homeowners across continents use Feng Shui practices for building placements and decoration of dwellings and workplaces. Feng Shui practice has some limitations such as conflicting opinions of experts and increased complexity when the dimension of time is taken into consideration. Still, Feng Shui as a practice is growing globally adjusting itself to regional and cultural challenges.

Controlling vibrations and noise in steel box girders is important for reducing noise pollution and avoiding discomfort to residents of dwellings along bridges. The fundamental approach to solving this problem involves first identifying the main path of transmission of the vibration energy and then cutting it off by using targeted measures. However, this requires an investigation of the characteristics of flow of vibration energy in the steel box girder, whereas most studies in the area have focused on analyzing its single-point frequency response and overall vibrations. To solve this problem, this study examines the transmission of vibrations through the segments of a steel box girder when it is subjected to harmonic loads through structural intensity analysis based on standard finite element software and a post-processing code created by the authors. We identified several frequencies that dominated the vibrations of the steel box girder as well as the factors that influenced their emergence. We also assessed the contributions of a variety of vibrational waves to power flow, and the results showed that bending waves were dominant in the top plate and in-plane waves in the vertical plate of the girder. Finally, we analyzed the effects of commonly used stiffened structures and steel-concrete composite structures on the flow of vibration energy in the girder, and verified their positive impacts on energy regionalization. In addition to providing an efficient tool for the relevant analyses, the work here informs research on optimizing steel box girders to reduce vibrations and noise in them.

최근 국내에서 건설되고 있는 주거건물과 주상복합건물은 단일건물보다는 다수의 건물군으로 구성되어 있는 경우가 많다. 단일건물의 경우도 환기 및 채광성을 비롯한 외관상의 문제와 상업성을 고려하여 하층부는 하나의 건물로 이루어지고 중 상층부로 갈수록 두개의 건물로 나누어져 두개의 동이 하나의 건물로 구성되어 있는 건축물이 많이 건설되고 잇는 추세이다. 이와 같이 높고 세장하며 복잡한 건축물은 질량과 감쇠가 낮을 뿐만 아니라 바람에 의한 건물군 사이의 상호작용효과 등에 의해 구조적인 안전성과 사용성은 풍하중에 의해 결정되어진다. 그러나 현재 다수의 건물군으로 이루어진 건축물의 구조설계시 인접한 동사이의 상호작용 효과에 대해 규명되어 있지 못하며 또한 그 상호작용 효과를 예측하기란 어려운 일이다. 따라서 본 연구에서는 현존하거나 현재 건설중에 있는 두 개동을 가진 건축물의 현황을 파악하여 그 패턴을 모델화 한 후, 풍동실험(wind tunnel test)을 통해 두 개의 동 사이의 인동거리에 따른 풍응답 상호작용 효과를 가속도응답을 중심으로 비교분석하였다. 본 연구의 결과로부터 건물군에 대한 풍응답 상호작용효과의 기초적 자료를 제시할 것이며 나아가 좀더 합리적이고 경제적인 구조설계를 위한 자료로 활용될 수 있을 것이다.

This study seeks what kind of factors influence to locate dwellings and to establish scenic spots in nature by a case study focused on a meandering stream. The study specially concentrates on the interrelationship between both residences and beautiful sceneries and a meander cut-off-area that reveals a special topographical characteristics, located at Samji village in Youngyang-eup, Youngyang-gun, Koungsangbuk-do. The meander cut-off area, developed at the middle or upper reaches of a river, often makes up specific landscapes such as precipitous cliffs, sheer cliffs and caves. And the area where is specially created by sudden change of flow due to erosion perceived by the cut surface to be the most beautiful scenic spot. These beautiful landscapes were used to be called as Dae, Dam or Gul and managed by Confucian scholars who enjoy refined taste and devote themselves to the study in nature. Moreover, the Ku-Hado-literary means the area of ex-flow-made the scholars' lving with a well prepared basis for agriculture where supplied a cornucopia of organic matters and water. The merit of agriculture made it possible that the scholars became economically independent, and the fact might be the essential point why the meander cut-off area took noticed. Actually, Cho-family has been in Smaji Village for generations, producing a large number of scholars and keeping the actual power of the region. The physical shape of the meander cut-off area, cozily surrounded by mountains, is considered as a good place for the dwelling due to the influence of traditional sight of view for location and P'ungsuchiri which is known as Feng Shui in China and geomancy in the western world. It is a fruit in it own way that we could find the ancestors' discernment and wisdom from this study, who have lived their lives adapting themselves to the given natural environment and also utilizing the nature wisely. But this is a current-argued study on the meander cut-off area. Follow-up studies have to be continued about the landscapes of the meander streams and the meander cut-off areas scattered all over the country except Samji Village and draw the characteristics from the comparative analysis.

As China has the largest number of elderly people in the world, the issue of the aged people has been a serious matter of concern in Chinese government and society and many studies have been done so far. However, the studies about the dwellings of the aged people that support their basic life are still insufficient. For this reason this study intends to identify the differences in elderly people's preferences according to their situations in aged life. This study surveyed 152 elderly residents aged 50 and over including early aged people in Beijing China about their residential preferences (types of residence, location of residence, size of residence, types of ownership) according to the four types of their situations in aged life, healthy couple, sick couple, healthy single and sick single. The survey conducted from 2013 April 10th to 15th. The results were as follows: Firstly, as the elderly situation became worse, preference for the independent residence decreased very rapidly while the preference for the elderly welfare facilities dramatically increased from the 0 point of the healthy couple and the preference for the elderly welfare facilities marked the highest point in case of the worst situation of sick single. Secondly, among the four different situations preferences for the urban residence were the highest and as the aged people's situation becomes worse, their preferences for urban life increased. Thirdly, healthy couple preferred a large size residence but as their elderly situation becomes worse, their preferences for the large size decreased and their preferences for small size increased dramatically, and in case of elderly singles, preferences for small size residence exceeded their preferences for large size residence. Fourthly, as elderly situation became worse preference for owning residence decreased and preference for rental residence increased and in case of the worst situation of sick single, preference for rental residence was higher than their preferences for their own residence. With this view of point, the residential preference of elderly people changes along with their aging situations. Thus, the government should consider the variable aging market, and develop a variety of aging residence which, can satisfy the different groups of elderly.

Engineering phase of dairy housing systems has close connection with the milk produc- tivity of dairy cattle, the quality of milk, extension of dairy production systems, labor- saving in management of dairy cattle and the like. Moreover, the rate of investment of dairy housing facilities is of relatively high level, However, there has been almost no research effort for the improvement of engineering aspects of dairy housing systems in Korea. The purpose of this study is to find out general engineering problems and to recomm- end the improvement in dairy housing systems in Korea. Field survey by means of questionaire, direct measurements, taking pictures and sketching was conducted to get necessary information for the study. Kyung-ki Do region was firstly chosen for sampling area since it has included more than half of the number of dairy farms of the whole country. The results obtained are summarized as follows: 1. In overall dairy farm layout, the dwellings of workers were ignored in the light of sanitary environment 2. The layout of stalls in a dairy barn belongs mostly to the type of double-row face-out, which is compatible with the emphasis of manure disposal activities. 3. While the width and length of stalls were sufficiently close to the standard dimension, the width of mangers was much less than the standard dimension. 4. The width and depth of manure gutters and the width of working alleys were much. less than the standard dimension. 5. The mooring equipment was mostly in the classes of chain or rope. The watering equipment was not facilitated independantly except the one cese of using watercup. 6. The bucket milkers with one or two bucket milkers with the capacity of two cattles. each were used as milking equipment in most dairy farms. 7. There were only few milk rooms independently spaced from other space, in which the arrangement of milking equipment was much less than the standard condition. 8. The lounging ground area was averaged to be sufficient for the activity of dairy herd. 9. Silos for silage used during winter consisted of mostly bunker silos, trench silos and underground vertical silos. Ordinary vertical silos were considered for the farmers to be inconvenient for the labor saving. 10. From the view point of heat conservation and moisture removal within the dairy barns, windows were not flexible for the easy ventilation and ceiling part was not adequate for temperatur maintenance. 11. Waste treatment and disposal systems were not provided with most dairy farms, therefore the livestock waste pollution problems would be serious in the near future.
