  • This research was designed to explore the meaning of housing among Korean Chinese in Harbin, China. In particular, the meaning of housing was examined by using the pathway approach. Utilizing qualitative research methods, this study administered the in-depth interview on the oral history of an individual life, and the 5 elderly persons in their 60s and 70s participated in the individualized interviews that were conducted from May 28 to 31 in 2010. The main findings of meaning of housing were as follows; 1. Similarly to the meaning of housing in 1970s and 1980s in Korea, house was viewed as both a shelter for family members and relatives and a place for their comfort. 2. Prior to multi-story residences, Harbin had only 3 different forms of single-story houses available; Chinese style with Kang and soil room(地室), Korean style with 'Ondol', and Russian style with open floor and Pechka, The promotion at work enabled participants to move to multi-story residences, their moving time varied from 1970 to 1991, and the residential moving determined their current housing status. 3. Multi-story residences were available around 1970s, floor-heating system was introduced from 1990s, and high-rise apartments were built from 1998. Korean Chinese(朝鮮族) weren't satisfied with the spatial composition of individual units embedded into the Chinese culture, especially, entrance, kitchen, bathroom and veranda. 4. Based on assimilation through socialism, adaptation to socialist society and capitalist acculturation, the lifestyles of the interviewees were categorized into five types - capitalist-proactive(Ms. KS), socialist-pragmatic(Ms. J), socialist-inducive(Ms. KY), family centered-conservative(Ms. L), and socialist-adaptive(Ms. P). This study implies that housing-related services for Korean Chinese are necessarily provided so as to embrace their life style and cultural identity in housing design, and further studies need to be explored.

  • Aluminum nitride(AIN) thin films were deposited by reactive single ion beam sputtering using N2 or NH3 as reactive gas. The structural, compositional and optical properties of AIN thin films were characterized by XRD, GAXRD, TEM, SEM, XPS UV/VIS spectrophotometer, and FT-IR. All the deposited AIN thin films were amorphous by the analysis fo XRD and GAXRD. However, TEM analysis showed that AIN nano-crystallites were uniformly distributed in the films. The presence of Al-N bonds were also confirmed by FT-IR and XPS analyses. The optical bandgap of AIN films increased up to 6.2 eV and the transmittance was a-bout 100% in visible range with approaching the stoichimetric composition. Irrespective of using N2 or NH3 as reactive gas, the deposited AIN thin films had very smooth surface morphologies. Their refractive index ranged from 1.6 to 1.7.

  • This paper presents a model for evaluating the contribution by arch action to shear resistance in shear-critical reinforced concrete beams. Based on the relationship between shear and bending moment in beams subjected to combined shear and bending, the behavior of a beam is explicitly divided into two base components of the flexural action and the tied arch action. The compatibility condition of the shear deformation that deviates from Bernoulli bending plane is formulated utilizing the smeared truss idealization with an inclined compression chord. The Modified Compression Filed Theory is employed to calculate the shear deformation of the web, and the relative axial displacements of the compression and the tension chord by the shear flow are also calculated. From this shear compatibility condition in a beam, the shear contribution by the arch action is numerically decoupled. Then the validity of the model is examined by applying the model to some selected test beams in literatures. The results may confirm the rationale of the proposed behavioral model.

  • Recently, due to increases in the numbers of nursing students, there are many cases of clinical practice in remote areas other than in hospitals near a school. In this regard, the Korea Institute of Nursing Evaluation emphasizes the securing of safety, the provision of regulations, and countermeasures related to long-term practices of nursing students. The purpose of this study is to develop a safety management application for nursing students who are practicing at a distance. This application configuration consists of accommodation location information, nursing student location information check, and notification of the professor in charge. The location information of nursing students was based on their location on weekdays from 10 pm to 11 pm, due to the work schedule of the nursing students. For this reason, nursing students can use this app after their clinical practice; if the student is out of the safety radius or there is a problem, a risk notification can be provided through a service and a rescue request can be made.

  • The importance of environmental resources has been recognized over the world after Rio declaration(1992). so it is moved to monetarize environmental resources. The studies on the evaluation of nonmarket goods began also in the early 1990 in Korea. In practice the preliminary feasibility studies(PFS) are carried out since 1999 in case of major public investments projects. In PFS the Benefit-Cost analysis is practically used. which is considering the evaluation of environmental resources. But the methods for the evaluation have not been fixed up. In this study It is introduced to the theory and major methods for the evaluation of environmental resources. In the theory the evaluation is handled in aspect of demand function and supply function. The optimum level can be extracted from the two functions. In the method. travel cost method(TCM), hedonic price method(HPM) and contingent valuation method(CVM) are introduced according to the market structures.
