As almost community facilities in korean rural village have being showed signs of decrepitude, and have a lot of problems on scale and function, it hasn't made full use of almost community facilities. To resolve these problems, it is time to make different plan considered of elements, scale and function in community facilities. In this study, after being researched the present condition and interviewed local residents on target 25 administrative districts, it was sought diverse problems about community facilities and researched satisfaction measurement, activity of local residents. With Being based on this, we also drove from essential element about community facilities in korean rural village and sorted problems of community facilities as general disposition-structure-outdoor facilities-behavioral use. Therefore, it was applied to study area and ascertained the existence of problem. Thus, we found out the improving way for appropriate community facilities in korean rural village. It will be useful to make different plan for community facilities in korean rural village.

A significantly larger lateral load and moment are applied on a high speed railway bridge foundation than other bridge foundations. Therefore most of bridge foundations on Honam high speed railway project were designed by high strength steel pipe piles to resist lateral load and moment, which caused the increase of construction costs. In order to perform optimum design, it is important to estimate accurate lateral resistance when designing this type of structure. Lateral load tests were carried out based on the field design data with the purpose of examining the lateral behavioral characteristics of a railway bridge foundation. The standard load test method(ASTM D 3966) was used for field tests by applying twice of design load. Total four load tests were performed on high speed railway bridge foundations with strain gages installed by every 1m along piles to measure load-resistance characteristics under applied lateral loads. The back-calculated P-y curves from strain gages were compared with estimated P-y curves using theoretical methods based on geotechnical investment data. Back-calculated P-y curves from field tests for sand and clay ground conditions were presented in this paper, which are different from theoretical P-y curves. By using the research results of this study, more accurate estimations of pile design under lateral loads can be available for similar geotechnical conditions.

The nature of the classroom environment is an important variable to understand when fostering creativity for elementary children. Studies of the classroom climate, structure or interaction commonly depend on behavioral observations or reports from the teacher or other adult-observer. Recent studies have used self-report instruments completed by students regarding their perceptions of various aspects of their class (see Fraser, 1991). The purpose of this study was to determine the developmental differences in the ratings of classroom environment between Korean students who are gifted and their American peers. The My Class Inventory was administered to 141 elementary students in grades three, four, and five. There were 65 Korean students and 76 American students who were identified as gifted by their schools. Reliability coefficients were calculated for all scales (satisfaction = .68: friction, .67; competition = .57; cohesion = .73; difficulty = .22). Results of a multivariate analysis illustrated significant differences between students from Korea and students from America on the MCI. Univariate analysis of variance of cultural group by grade level were conducted for four of the five scales. Significant differences were found by country for the cohesion scale and by country at grade levels for the satisfaction scale. American children expressed greater satisfaction than their Korean counterparts at all grade level, but particularly at grade five. Implications for further research are discussed.

In order to gain implications for establishing competency-based education system in Korean medicine education, we examined several competence frameworks of medical education developed at international or national level, and compared the basic constitution and common elements. The competence frameworks of medical education consist of seven categories of communication, professionalism, critical thinking, medical knowledge, patient care, management, and public health. Medical knowledge consists of five sub-groups: normal structure and function; pathogenesis and mechanism of disease; principles of drug and treatment; psychological, behavioral and sociological principles; and public health and lifelong learning. In principle, competencies are further divided into sub-categories or combined with learning outcomes, and the field and the level of achievement is presented per item. This article aims at summarizing the competencies of a few globally leading medical institutions with the educational standard of Korean Medicine in mind.

Characteristics of a counter flowing diffusion flame, which is formulated by an oppositely-injected methane-jet flow in a narrow channel of a uniform air flow. The location of the flame fronts and the flame lengths were compared by changing the flow rates of fuel. To distinguish the effects of the narrow channel on the diffusion flame, a numerical simulation for an ideal two-dimensional flame was conducted. Overall trends of the flame behavior were similar in both numerical and experimental results. With the increase of the ratio of jet velocity to air velocity flame front moved farther upstream. It is thought that the flow re-direction in the channel suppresses fuel momentum more significantly due to the higher temperature and increased viscosity of burned gas. Actual flames in a narrow channel suffer heat loss to the ambient and it has finite length of diffusion flame in contrast to the numerical results of infinite flame length. Thus a convective heat loss was additionally employed in numerical simulation and closer results were obtained. These results can be used as basic data in development of a small combustor of a nonpremixed flame.

Composite beam, which combined the material characteristic of the steel and concrete, has been widely used in the construction of various building and bridge system. For the effective application of the composite beam, the composite action on the composite interface between the concrete element and the steel element should be achieved by shear connectors. The behavioral characteristics of composite beam are related with the degree of interaction and the degree of shear connection according to the shear strength and shear stiffness of the stud shear connectors. These two concepts are also affected by the number of installed shear connector and the strength of composite materials. In this study, experimental and analytical evaluations of the degree of shear connection affected by stud diameter were conducted, and the relationship between structural behavior and the degree of shear connection was verified. The very small difference among the ultimate loads of the specimens depending on the change of the degree of connection was possibly because of the dependence of the ultimate load on the characteristic of plastic moment of the composite beam.

We investigated the reduction of etching damage by additive O$_2$ in etching gas and recovery of etching damage by O$_2$ annealing. The PZT thin films were etched using additive Ar or O$_2$ into Cl$_2$/CF$_4$ gas mixing ratio of 8/2. In order to recover ferroelectric properties of PZT thin films after etching, the etched PZT thin films were annealed at 600 C in O$_2$ atmosphere for 10 min. The remanent polarization is decreased seriously and fatigue is accelerated in the PZT sample etched in Ar/(C1$_2$+CF$_4$) plasma, whereas these characteristics are improved in O$_2$/(Cl$_2$/CF$_4$). From x-ray photoelectron spectroscopy (XPS) analysis, the intensities of Pb-O, Zr-O and Ti-O peaks are changed and the etch byproducts such as metal chloride and metal fluoride are reduced by O$_2$ annealing. From electron probe micro analyzer (EPMA) and auger electron spectroscopy(AES), O$_2$ vacancy is observed after etching. In x-ray diffraction (XRD), the structure damage in the additive O$_2$ into C1$_2$/CF$_4$ is reduced and the improvement of ferroelectric behavioral annealed sample is consistent with the increase of the (100) and (200) PZT peaks.
