In this study, intention type was assigned to determine appropriate conservation and use of the Baekdudaegan Protection Area. To determine intention type, 84 indices were integrated into 7 types: the Natural Environment Protection District, Natural Scenic District, Agriculture and Forestry Promotion District, Living Environment Protection District, Education/Culture/Arts Promotion District, Recreation/Tourism Promotion District, and Disaster Management District. Intention types were decided by comparing the occupying proportion of the intention types for each watershed segment in which the Seoraksan, Taebaeksan, and Sockrisan region boundaries were included. Weight values were applied to each of the seven intention types because each type did not play an equal role in the target regions. Most regions were classified as Natural Environment Protection intention types because the Baekdudaegan area is regulated with strong forestry and environmental protection acts; thus, the weight values related to nature protection were higher than those for other types. To supplement the results from this study, additional research is needed to determine the intention type and weight for each region, and it will also be necessary to integrate sociocultural factors and field survey data.

Entrepreneurial Orientation (EO hereafter) can be described as firm level entrepreneurial tendencies. Initially Miller(1983) clarifies the construct of EO, and defines an "entrepreneurial firm as one that engages in product marketing innovation, undertakes somewhat risky ventures, and is first to come up with proactive innovations, beating competitors to the punch". After Miller (1983), Covin & Slevin(1989) adopted EO as a uni-dimensional construct, and insisted that these three dimensions can be combined into a single scale. Since Covin & Slevin(1991), researchers including Lumpkin & Dess(1996) have explored the usefulness of EO. However not many attempts have been tried to summarize the results of previous empirical researches, and to suggest future research directions. To examine and find implications, current study classified the effects of EO as 1) main and mediating effects, 2) moderating effect, 3) other effects, and provide theoretical and empirical validation of EO, which suggested by Miller(2011). After analyzing research results published in major international and Korean journals in each research domain, current paper summarizes and evaluates previous research results, and then suggests research directions for the future. In doing so, we hope to provide some theoretical and practical insight for management of small and medium sized firms.

This paper examines factors like career orientation, social & cultural perception and self-efficacy that influence on entrepreneurial intention of college students, and also comparison of determinant factors of the entrepreneurial intention among Korean and Chinese students. First, in terms of technical competence orientation, security orientation, autonomy orientation, Korean students showed higher than Chinese students, while Korean students showed lower entrepreneurial creativity orientation. In terms of corporate image and entrepreneurial intention, Korean students showed lower than Chinese students. Second, entrepreneurial creativity orientation out of career orientation among Korean and Chinese Students had significant positive effects on entrepreneurial intention, while security orientation had marginally negative effects on entrepreneurial intention. Entrepreneurial self-efficacy and corporate image had the positive effects on entrepreneurial intention together. The Chinese students, however, had the positive effects in network environment for analysis in this study only.

This study is a study that designed in-building antennas with improved orientation to improve 5G quality in buildings as 5G is stabilized and more and more traffic is expected to occur in buildings. Instead of applying the forward arrangement of antenna elements, which is the Yagi antenna propagation orientation principle, the antenna design method of vertical arrangement applied to the base station antenna was proposed, and it was confirmed through experiments that antenna orientation increased. According to the experimental results, the directivity did not increase significantly within 10m of the separation distance from the antenna, but the directivity increased by about 3dB at the distance separated by more than 10m. Considering that the wireless environment in the building has various variables such as structure of internal structure, materials such as concrete and glass, closed space, and walls, it is expected that antenna with improved orientation can expand the scope of 5G quality improvement and maintain stable communication service in the building.

In this paper, we fabricated dual polarization microstrip array antenna to analyze the performance of polarization diversity of each antennas beamwidth and recommend suitable polarizations diversity antenna under indoor environments. The proposed antennas which have directional beam patterns are small, light and thin. Also they are $1\times4$ array and $4\times4$ array antenna with $70^{\circ}$, $20^{\circ}$ beamwidth, respectively. The center frequency is 1890 MHz, IMT-2000's frequency. We also measured the antennas characteristics of each beamwidth in various waveguide structured corridor and compared then with the case of space diversity using the dipole antenna. The measurement shows that the polarization diversity using directional dual polarization microstrip array antennas has more 1~7 dB diversity gain than the space diversity using the dipole antenna. Therefore, the proposed antennas are expected to be efficiently used for the design of optimal directional beam pattern antenna and diversity system for indoor environments.

This study sought to examine how internal market orientation of service organizations affects the service providers' adaptive service behavior and to determine what psychological processes go through for this purpose. To achieve this purpose, based on previous research, a research model was set up to predict that internal market orientation of service organizations will increase service providers' adaptive service behavior by continuously mediating the psychological processes of person-environment fit and work engagement. To test the hypothesis, a survey was conducted and data were collected from nutritionists at consignment catering companies located in Busan and Gyeongnam. As a result of testing the hypotheses proposed in this study's research model, internal market orientation increased person-job fit and person-organization fit, which are key elements of person-environment fit. And, it was confirmed that person-job fit and person-organization fit have a positive effect on work engagement. Additionally, work engagement improved service providers' adaptive service behavior. Lastly, this study confirmed that the influence of internal market orientation on adaptive service behavior is continuously mediated by person-environment fit and job enthusiasm.

In this paper, an algorithm that enhances the conventional directional CSMA/CA protocol in IEEE 802.15.3c is proposed under saturation environments. For the algorithm, a Markov chain model is presented and analyzed in no-ACK mode. The effects of directional antennas and the features of IEEE 802.15.3c MAC are considered in the model. The optimal sizes of contention window are derived from the numerical results. The numerical results show that the proposed directional CSMA/CA algorithm outperforms conventional one. The overall analysis is verified by simulation. The obtained results provide the criterion for selecting the optimal parameters and developing a MAC protocol that enhances the performance of mmWave WPANs.
