This study empirically examines the relationship between the characteristics of a company and its performance through open innovation. It was intended to accept open innovation as a strategic means to overcome various situations in which companies faced and to understand it as a process of generating corporate performance. In various situations, companies must overcome environmental and internal factors. As an environmental factor, the dynamics of the market and the dynamics of technology allow for the adoption of open innovation, which in turn becomes a strategic tool for generating results. In addition, the internal environment of the company should strengthen the organization's capacity considering the characteristics of the company. In order to reinforce entrepreneurial orientation, openness of organizational culture, delegation and R & D capabilities, which are internal characteristics of the company, open innovation has a positive effect on the performance of the company. In overcoming the environment given to the company, open innovation was found to be an important medium for generating various results for the company. For this study, we conducted a structured questionnaire survey on 176 Korean companies. This study suggests that open innovation is strategically accepted and understood as a management strategic philosophy in order to overcome the environment in which a company is faced and generate results.

Intensive studies have been focused on conditions for business foundation and the entrepreneurship in light of management, economy, and social psychometrics. This study focused on potential effect of entrepreneurial characteristics on environment for entrepreneurial intentions in establishment of orientation of entrepreneurial intentions. Among various factors affecting on starting small and medium size enterprises, how entrepreneur's personal characteristics is related on entrepreneurial intentions was investigated. Manifest questionnaire was distributed among Venture to the professional graduate students, graduate entrepreneurship, and small business start-educated founders in order to deduce the relationship between the entrepreneurial characteristics and the environment of entrepreneurial Intentions. Previous studies and the literature survey were carried out to support for statistics of the questionnaire. 550 answers were collected and analyzed to find that propensity for achievement, innovation, enterprising, risk taking and creativity are key factors influencing inauguration of an enterprise. We have found that among these, risk taking, creativity, and innovation are analyzed to be as a regression coefficient but enterprising a side regression coefficient. Since this study can find its limitation in that comprehensive fields of entrepreneurship were analyzed in general, the result of this study should be used with caution, until more is known about its accessibility for predicting of success or failure of Start-up Company.

Background: Early detection is a critical part of reducing the burden of breast cancer and breast self-examination (BSE) has been found to be an especially important early detection strategy in low and middle income countries such as Malaysia. Although reports indicate that Malaysian women report an increase in BSE activity in recent years, additional research is needed to explore factors that may help to increase this behavior among Southeastern Asian women. Objective: This study is the first of its kind to explore how the predicting variables of self-efficacy, perceived barriers, and body image factors correlate with self-reports of past BSE, and intention to conduct future breast self-exams among female students in Malaysia. Materials and Methods: Through the analysis of data collected from a prior study of female students from nine Malaysian universities (n=842), this study found that self-efficacy, perceived barriers and specific body image sub-constructs (MBSRQ-Appearance Scales) were correlated with, and at times predicted, both the likelihood of past BSE and the intention to conduct breast self-exams in the future. Results: Self-efficacy (SE) positively predicted the likelihood of past self-exam behavior, and intention to conduct future breast self-exams. Perceived barriers (BR) negatively predicted past behavior and future intention of breast self-exams. The body image sub-constructs of appearance evaluation (AE) and overweight preoccupation (OWP) predicted the likelihood of past behavior but did not predict intention for future behavior. Appearance orientation (AO) had a somewhat opposite effect: AO did not correlate with or predict past behavior but did correlate with intention to conduct breast self-exams in the future. The body image sub-constructs of body area satisfaction (BASS) and self-classified weight (SCW) showed no correlation with the subjects' past breast self-exam behavior nor with their intention to conduct breast self-exams in the future. Conclusions: Findings from this study indicate that both self-efficacy and perceived barriers to BSE are significant psychosocial factors that influence BSE behavior. These results suggest that health promotion interventions that help enhance self-efficacy and reduce perceived barriers have the potential to increase the intentions of Malaysian women to perform breast self-exams, which can promote early detection of breast cancers. Future research should evaluate targeted communication interventions for addressing self-efficacy and perceived barriers to breast self-exams with at-risk Malaysian women. and further explore the relationship between BSE and body image.

The purpose of this study is to consider the relationship between point of view and prospect behavior occurring in the experience of a painted landscape. This study analyzes one hundred scenes from the 'real landscape painting' by Kyumjae, one of the most famous landscape painters in 18th century Korea. The results of the study are as follows: 1. It clarified that Kyumjae's real landscape painting's 100 scenes have many view points such as roads, bridges, pavilions, mansions, towers, terraces, hillsides, bases of mountains, broad flat roots, brooksides, and ferries that are apt to occur in the experience of a landscape. The spatial characteristics of view points are expanded fields of vision, evening and night scenes, edges of landforms and structures from which to improve ones vantage point. 2. It showed that 99 out of real landscape painting's 100 scenes depict a view point'to look'and 79 of 'to look through', 73 of 'look around'and 24 of 'to look over'. 3. It showed that real landscape painting's 100 scenes depict that the view point 'to look' is mainly upon a road from which people are looking over an elevated landscape such as the top of a mountain or rockwall. The view behaviors of looking down are depict 15 pavilions, 14 mansions, 2 broad rocks and 10 mountain tops on which people experience landscapes such as fields, rural communities and streams. The view behaviors to look depict 33 ships, 24 roads, 24 pavilions, 19 mansions and 12 terraces on which people experience landscapes such as distant views of mountains, rivers and landscapes. The view behaviors to look around to obtain orientation of landscape are depict 16 pavilions, 10 mountaintops. To glimpse on the way of journey depict 33 ships and 29 roads. To look over depict 11 mansions and 6 pavilions on which experience borrows the landscape. To look through landscapes such as rivers, mountains and rockwalls depict 15 roads, 14 pavilions and 11 mansions. To exchange looks depict 30 ships, 14 roads, 12 pavilions and 12 mansions. We expect that these results might give clues toward the experience of landscapes and the practice of landscape design methods which select viewpoints, and in the design of view points suitable to prospect behaviors.

There are various methods to evaluate tree vigor. Cambial electrical resistance represents tree vigor using the method of electrophysiological diagnosis. This study investigated the vigor of several tree species using Shigometer, and compared the differences among the species. The factors, such as foliation, trunk orientation and bark temperature, which affect electrical resistance were also investigated. The needle penetration into cambium was controlled to keep the depth consistent in order to minimize measurement error. Each of three trees were selected from Zelkova serrata, Ginkgo biloba, Metasequoia glyptostroboides, Pinus koraiensis, and Liriodendron tulipifera. The electrical resistances were measured at 60 and 120 cm height of the stem in 4 directions from March until May 2011. The soil conditions in surrounding areas and tree stress responses were also measured. The results were analyzed for the relationship between electrical resistance and the affecting factors. The electrical resistance showed a relatively higher level before foliation until mid-March. The values started to decline from April and recorded a minimal level on May 11. The changes of soil moisture, soil electric conductivity, and tree stress responses during the measurement period showed a similar trend to that of electrical resistance. The Pinus koraiensis, an evergreen conifer, showed few changes on the electrical resistance values during the measurement period. Zelkova serrata, Ginkgo biloba, and Metasequoia glyptostroboides showed the highest bark temperatures and lowest electrical resistances at their south-facing stem. Shigometer can provide measures simple to assess tree vigor in the fields, and to the management of trees.

By analyzing a nationwide survey on Korean publics, this study examines the social determinants of public support for three types of scientific research-basic research aimed at pure knowledge, applied research toward industrial application, and research for social problem-solving which aims to enhance ordinary citizens' quality of life. The present study finds the differential effects of social- and political value orientations on the level of public support for respective types of research. As ones have more progressive in their subjective political orientations, they are more likely to support research for social problem-solving than other types of research, while conservatives tend to support basic research and those with neo-liberal ideology tend to support applied research. The Korean public also tends to perceive research for social problem-solving as a counter to basic research while it has been developed against the conventional emphasis on applied research in Korea. Also, the level of support for research for social problem-solving increases with the higher level of trust in scientific authority and expertise, while it has been developed against expertism and included public engagement in science as an important element. Finally, those who have lower income tend to support for research for social problem-solving than other types of research. The implications of these findings are discussed.

The purpose of this study is to analyze the astronomical thinking level of elementary, middle, and high school students using ordered multiple choice items. For this purpose, we constructed a questionnaire comprising three items about spatial thinking and system thinking. This survey was conducted and applied to 1,066 students in the 5th grade, 8th grade, and 11th grade in 12 schools located in Gangwon Province. The collected student response data were analyzed by applying inferential statistics of classical test theory and Rasch model. The results of the analysis were as follows; First, in the level of spatial thinking, students were able to grasp the spatial location and orientation of the celestial body, but were not able to convert the celestial motion of two-dimensional plane into three-dimensional plane, and it was revealed that there is no statistically significant difference in the spatial thinking of students among grade levels. Second, in the level of system thinking, students were able to identify the components and relationship between components of the celestial motion system, but could not identify the patterns of the system, and it was revealed that there was statistically significant difference among the system thinking of students in different grade levels, unlike in spatial thinking. Third, the astronomical thinking expressed in certain context (content) was very similar regardless of grade level, Through this, we could confirm the context-dependency or content-dependency of the astronomical thinking of students. It is expected that the results of this study can be used as basic data for exploring ways to enhance astronomical thinking level in school science classes.

A computer program to numerically predict the permeability tensor of fractured rocks is developed using information on discontinuities which Borehole Televiewer and Borehole Image Processing System (BIPS) provide. It uses orientation and thickness of a large number of discontinuities as input data, and calculates relative values of the 9 elements consisting of the permeability tensor by the formulation based on the EPM model, which regards a fractured rock as a homogeneous, anisotropic porous medium. In order to assess feasibility of the program on field sites, the numerically calculated tensor was obtained using BIPS logs and compared to the results of pumping test conducted in the boreholes of the study area. The degree of horizontal anisotropy and the direction of maximum horizontal permeability are 2.8 and $N77^{\circ}CE$, respectively, determined from the pumping test data, while 3.0 and $N63^{\circ}CE$ from the numerical analysis by the developed program. Disagreement between two analyses, especially for the principal direction of anisotropy, seems to be caused by problems in analyzing the pumping test data, in applicability of the EPM model and the cubic law, and in simplified relationship between the crack size and aperture. Aside from these problems, consideration of hydraulic parameters characterizing roughness of cracks and infilling materials seems to be required to improve feasibility of the proposed program. Three-dimensional assessment of its feasibility on field sites can be accomplished by conducting a series of cross-hole packer tests consisting of an injecting well and a monitoring well at close distance.

Interface recombination velocity in $Al_{x}$G $a_{1-x}$ As-GaAs and $Al_{0.85}$, G $a_{0.15}$ As-GaA $s_{1-y}$S $b_{y}$ heterojunction systems is studied as a function of lattice mismatch. The results are applied to the design of highly efficient III-V heterojunction solar cells. A horizontal liquid-phase epitaxial growth system was used to prepare p-p-p and p-p-n $Al_{x}$G $a_{1-x}$ As-GaA $s_{1-y}$S $b_{y}$-A $l_{x}$G $a_{1-x}$ As double heterojunction test samples with specified values of x and y. Samples were grown at each composition, with different GaAs and GaAs Sb layer thicknesses. A method was developed to obtain the lattice mismatch and lattice constants in mixed single crystals grown on (100) and (111)B oriented GaAs substrates. In the AlGaAs system, elastic lattice deformation with effective Poisson ratios .mu.$_{eff}$ (100=0.312 and .mu.$_{eff}$ (111B) =0.190 was observed. The lattice constant $a_{0}$ (A $l_{x}$G $a_{1-x}$ As)=5.6532+0.0084x.angs. was obtained at 300K which is in good Agreement with Vegard's law. In the GaAsSb system, although elastic lattice deformation was observed in (111) B-oriented crystals, misfit dislocations reduced the Poisson ratio to zero in (100)-oriented samples. When $a_{0}$ (GaSb)=6.0959 .angs. was assumed at 300K, both (100) and (111)B oriented GaAsSb layers deviated only slightly from Vegard's law. Both (100) and (111)B zero-mismatch $Al_{0.85}$ G $a_{0.15}$As-GaA $s_{1-y}$S $b_{y}$ layers were grown from melts with a weight ratio of $W_{sb}$ / $W_{Ga}$ =0.13 and a growth temperature of 840 to 820 .deg.C. The corresponding Sb compositions were y=0.015 and 0.024 on (100) and (111)B orientations, respectively. This occurs because of a fortuitous in the Sb distribution coefficient with orientation. Interface recombination velocity was estimated from the dependence of the effective minority carrier lifetime on double-heterojunction spacing, using either optical phase-shift or electroluminescence timedecay techniques. The recombination velocity at a (100) interface was reduced from (2 to 3)*10$^{4}$ for y=0 to (6 to 7)*10$^{3}$ cm/sec for lattice-matched $Al_{0.85}$G $a_{0.15}$As-GaA $s_{0.985}$S $b_{0.015}$ Although this reduction is slightly less than that expected from the exponential relationship between interface recombination velocity and lattice mismatch as found in the AlGaAs-GaAs system, solar cells constructed from such a combination of materials should have an excellent spectral response to photons with energies over the full range from 1.4 to 2.6 eV. Similar measurements on a (111) B oriented lattice-matched heterojunction produced some-what larger interface recombination velocities.ities.ities.s.

Recent economic slump is making the construction industry's overall construction business environment worse. Contractors which are under the legal management and/or walk out are to the brink of 25 companies according to the Construction association of Korea released in 2011. It means that existing construction companies are required to transform the fundamental ideology of existing operation framework, and besides, existing companies should be transformed to service industry in order to proceed further into the developing future industries. In this study, it will be chosen the internal marketing related factor like 'Satisfying employees, internal customer, are the first thing to do in order to satisfy external customer.' which is about existing service industry field before its implementation in construction companies. In addition, appropriateness test will be performed including both interactions between each of the factors affect mutually and looking into any management improvement effects on contractors. And also, this proposal is suggested by approaching with internal marketing strategy which is both paradigm shift for customers by construction company members and another internal communication way as a means of overcoming the crisis of overall construction industry under currently happening.
