In this study, we fabricated the DAMLs using surface micromachining technology as well a low loss coupler for the millimeter-wave band applications using these DAMLs. The structure of DAML is that a signal line is supported on ground plane by dielectric posts. Therefore it has advantages about the loss characteristic and the stable structure. The other advantage of the DAML process is a simple and convenient technique using 4 mask steps, even if it has a micromachining technology. The lowest loss of the fabricated DAML was obtained 2.2 dB/cm at 110 GHz. To obtain the low loss characteristic, couplers were designed and fabricated by using DAMLs. The fabricated ring hybrid coupler has the coupling of 3.58 dB and the thru of 3.31 dB at 60 GHz. We can also obtain the coupling of 3.42 dB, the thru of 3.82 dB from fabricated branch line coupler at 60 GHz.

Micro small business start-ups are receiving financial and marketing support from government or public authority, but business closure rate is very high and it causes a hugh burden to households and national economy. This study aims to verify the causal relationship between the self-determination characteristic of small business start-ups and entrepreneurial intention through learning orientation and innovation ability. The man's intrinsic motivation of self-determination theory is expected to have an impact on the entrepreneurial intention of small business start-ups. The self-determination theory includes perceived autonomy, perceived competence, perceived relationship as independent variables. This study presented a research model for explaining the entrepreneurial intention of small business start-ups, and collected 260 survey responses from the small business start-ups In order to validate the proposed research model, PLS analysis is performed with valid 246 questionnaires. By PLS technique, the measurement reliability and validity of research variables are tested and the path analysis is conducted to do the hypothesis test. Path analysis shows that perceived autonomy does not significantly affect the learning orientation and innovation ability. On the other hand, perceived competence significantly influences learning orientation and innovation ability. Perceived relationships had significant influence on learning orientation. It is found that the parameters of learning orientation and innovation ability significantly influence the dependent variable of entrepreneurial intention. Based on the results, a policy and strategy for supporting small business start-up are presented.

The historical aspects, policies, institutions, awards and measurement results of scientific literacy and scientific culture development in Indonesia have currently attracted further exploration. This paper utilizes secondary data research, further analyzed by employing the Supplementary Analysis technique. The results revealed that the tradition of writing and publishing scientific journals in Indonesia has existed ever since the Dutch East Indies with the journal's publication entitled 'Natuurkundig tijdschrift voor Nederlandsch Indië' in 1850. To date, Indonesia has owned 5,990 nationally accredited journals. Policy support has been provided at the national and regional levels, despite limitations in cultivating literacy and reading habit. From the institutional perspective, Indonesia provides a wide array of public support, including the effort of the Ministry of Education and Culture for advocating the national literacy movement and the availability of a reference database and scientific access established by the National Library; the Indonesian Institute of Sciences, and the Ministry of Research and Technology. Similarly, in the award-related perspective, the Indonesia government has granted awards to individuals or groups and local governments engaging in the cultivation of scientific literacy and scientific culture. However, among the global measurements for literacy development in Indonesia (in 2020) recorded that three indicators scored less than those in 2019.

The inner and outer environment surrounding companies becomes more insecure and unpredictable due to sudden changes. Because the change of environment surrounding companies can deeply affect the existence of companies, continuous innovation of organization is required to develope management ability. Also, to conquer insecure present and future of companies effectively, organizations of companies have voluntarily coped with insecurities and intense competitions through endless organization innovation. Externally, globalization, openness, and relaxed regulation intensify competitions; consumers' requests get varied; consciousness of members of organizations have changed. Due to those factors, companies are placed in a situation that they should practice endless inner innovation. Internally, competitive power has weakened due to decline in productivity and inefficiency of indirect parts of company has increased. From those factors, managers increasingly request inner innovation and pursue organization innovation for the purpose of effective usage of extra resources and being prepared for the future. The managers who operate organization innovation think that systematized approach to organization innovation is the most practical, and actually operate the thought. However, the negative side of the thought is not neglectable. To minimize inner and outer resistance and to operate organization innovation successfully, some innovation strategies that properly reflect several issues related to organization innovation should be prepared. Another words, organization innovation should be operated differently by cases that if it focuses on personal perspective or on organization's. For many cases of our country, several techniques of organization innovation have been adopted in a short time and operated without making its original use. Therefore, this study looks into major Issues that should be considered for more successful operation of organization innovation, from both personal aspect and organizational aspect. When considering such aspects and operate organization innovation, there is more possibility to succeed on organization innovation. Now, Korean companies have overcame trial period and reborn as global companies. Take warnings by the ordeal under IMF administration, this is time to secure international competitive power by using developed innovation techniques and transform to superior company. Managers need to recognize that to try successful organization innovation is the shortcut to reborn as competitive company, and should take a continuous and profound search for decisive factors to succeed on organization innovation. To operate successful organization innovation, first, at the step of planning organization. innovation, the company should understand the company's capability, position in market and relationship with competitors. Then, the company should establish a distinguished innovation strategy which is of the whole company's aspect, so that the company can freely choose various technique of organization innovation that suits for the company's capability and needs, and unfold the organization innovation movement. Establishing strategy in the aspect of the total company is very important because it offers clear focus of the purpose of adopt, priority and distribution of resources. Second, at the step of operating organization innovation, the company should define concrete purpose and method to evaluate the results that are expected to obtain by adopting organization innovation in advance. While pushing forward, the company should set proper time of examination(milestone) and inspect if expected results are shown. Third, at the step of afterward management of operating organization innovation, the company requires a thorough afterwards verification if targeted results are obtained and of confirmation of successful or failure factors. Also, the company should cultivate specialists in the company who can accumulate and continuously spread the know-how learned during organization innovation promotion, so the know-how don't remain only in certain departments or to a few people in charge. The company should also give effort to maintain the accumulated innovation techniques to be continued.

The target costing technique, mathematically discussed by Sauers, only uses the $C_p index along with Taguchi loss function and $\bar{X}$-P control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the $C_p value to $\bar{X}$-P control charts to obtain goal control limits. Studies have shown that the point estimator of the $C_p index, $C_p, could vary from time to time due to the sampling error. The suggested approach is to use confidence intervals, especially the lower confidence intervals, to replace the point estimator. Therefore, an improvement on target costing technique is presented by applying the lower confidence interval of the $C_p index and using both Taguchi and Spiring's loss functions together with $\bar{X}$-P charts to make this technique more robust in practice. An example is also provided to illustrate how the improved target costing technique works.

Channel-based radio-frequency fingerprinting such as a channel impulse response (CIR), channel transfer function (CTF), and frequency coherence function (FCF) have been recently proposed to improve the accuracy at the physical layer; however, their empirical performance, advantages, and limitations have not been well reported. This paper provides a comprehensive empirical performance evaluation of RF location fingerprinting, focusing on a comparison of received-signal strength, CIR-, CTF-, and FCF-based fingerprinting using the weighted k-nearest neighbor pattern recognition technique. Frequency domain channel measurements in the IEEE 802.11 band taken on a university campus were used to evaluate the accuracy of the fingerprinting types and their robustness to human-induced motion perturbations of the channel. The localization performance was analyzed, and the results are described using the spatial and temporal radio propagation characteristics. In particular, we introduce the coherence region to explain the spatial properties and investigate the impact of the Doppler spread in time-varying channels on the time coherence of RF fingerprint structures.

The paper aims to evaluate the combination of strategies that influence the success of New Technology Based Firms (NTBFs) located in isolated areas with resource constraints. We utilize the Kauffman Firm Survey to construct a subset of 224 firms operating in primary metal manufacturing industries and who are located in non-thriving areas. We focus on the impact of technological strategy, in the form of Inward Technology Licensing (ITL), combined with financial strategy, in the form of increased financial slack. Using a negative binomial-specification technique to model these relations, we find that ITL positively impacts internal innovation in the firm and this relation is strengthened by the presence of greater financial slack. This positive impact of financial slack supports the behavioral theory of the firm rather than agency theory in that financial slack enables further innovation rather than stifling it. This research confirms the importance of resource acquisition, suggesting that entrepreneurs may utilize external sources of knowledge in an effort to build a favorable situation when facing the challenges of location. Finally, by presenting evidence showing the compatibility of a financial strategy with a knowledge strategy (ITL), this study emphasizes the importance to entrepreneurs of choosing the proper combination of varying strategies.
