The management strategies of each company has been changed fundamentally owing to the emergence of digital economics by using internet. Therefore the efficient management of global e-port causes the main issues not only effect the survival and growth of ports but also exert new opportunities and fatal threats on them. Under the circumstances of these change, the Kwangyang port have to introduce e-biz for the purpose of increasing the level of their competition. The focus of this article is to suggest some strategies on the implementation of Kwangyang Global e-port in Korea. To analyse the e-port realities, I first reviewed the trends of e-marketing and e-biz. I chose and analysed website of four ports like Hongkong, Singapore, Antwerp and Hamburg as successful global e-port models. This article is focused to suggest the theoretical background by analysing the strategic points of Kwangyang global e-port which are divided in 6C: Contents, Communities, Connection, Commerce, Communication and Customization. This paper analyses many problems of Gwangyang port and presents various develpment ways to activate Gwangyang port. In order to be a global e-port, first of all Gwangyang port must improve global web-site by 6C. And also Gwangyang port have to constitute logistics hub site, create infrastructure needed to run electronic business more easily over the internet, establish nationwide network of industries, build up marine and port logistics information system.

Background: In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. Methods: A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2016 were retrospectively reviewed, including 47 in the triple-port group and 26 in the single-port group. Statistical analysis was performed after propensity score matching. Patients were matched on a 1-to-1 basis. Results: Operative time and intraoperative blood loss in the triple-port group and the single-port group were similar ($189.4{\pm}50.8minutes$ vs. $205.4{\pm}50.6minutes$, p=0.259; $286.5{\pm}531.0mL$ vs. $314.6{\pm}513.1mL$, p=0.813). There were no cases of morbidity or mortality. No significant differences in complications or the total number of dissected lymph nodes were found between the 2 groups. In the single-port group, more mediastinal lymph nodes were dissected than in the triple-port group ($1.7{\pm}0.6$ vs. $1.2{\pm}0.5$, p=0.011). Both groups had 1 patient with bronchopleural fistula. Chest tube duration and postoperative hospital stay were shorter in the single-port group than in the triple-port group ($8.7{\pm}5.1days$ vs. $6.2{\pm}6.6days$, p=0.130; $11.7{\pm}6.1days$ vs. $9.5{\pm}6.4days$, p=0.226). However, the differences were not statistically significant. In the single-port group, the rate of conversion to multi-port VATS lobectomy was 11.5% (3 of 26). The rates of conversion to open thoracotomy in the triple-port and single-port groups were 7.7% and 3.8%, respectively (p=1.000). Conclusion: In comparison with the triple-port group, single-port VATS lobectomy showed similar results in safety and efficacy, indicating that single-port VATS lobectomy is a feasible and safe option for lung cancer patients.

Port marketing using websites in the e-business environment is essential in response to the competition to become hub ports, especially since shipping companies, ports' major customers, are being pressed by shippers to reduce logistics costs and introduce large ships to realize economies of scale, thereby reducing the number of ports of call. In this sense, this study intends to approach the port industry from the perspective of e-business and suggest vitalization methods using Gwangyang Port websites(6C; contents, community, communication, connection, commerce, customization) as one of the ways to turn it into Northeast Asia's hub port of logistics.

The power-controlled six-port element that can control the local oscillator signal power and receiving RF signal power was designed and implemented in this paper. The direct conversion six-port element configuration was proposed, which provides the constant six-port output power by controlling the six-port input power with various signal strength. The direct conversion six-port element protects the power detector element of six-port receiver from the saturation status and compensates the transmission performance degradation. For implementation of power-controlled six-port element, the power-controlled six-port element including the power controller was analyzed. The implemented power-controlled six-port element shows the power control capability of 36 dB and gain imbalance of about 1.6 dB, phase imbalance of about $4^{\circ}$ in the frequency range of 1.69 GHz. The measured results show the good performance as direct conversion front-end element.

In this paper, we suggest a new 4-port receiver instead of 6-port schematic for the demodulation of BPSK. The designed receiver is implemented by a ring-hybrid balun, two power detectors, and a comparator For the validity of the proposed receiver, we demonstrate a BPSK modulator/demodulator at 2.45 GHz. The measured data shows that the proposed 4-port receiver can successfully demodulate a data rate of 1 Mbps.

The multi-band six-port phase correlator using metamaterial was designed and fabricated in this paper. The lumped metamaterial structure that can process the dual-band receiving signal was analyzed. Based on the analyzed results, the small-sized metamatrial six-port phase correlator for multi-band direct conversion method was proposed and fabricated. Also, the resistive power divider and $90^{\circ}$ hybrid coupler that comprises the six-port phase correlator were implemented based on the scattering parameters of metamatrial six-port phase correlator. The measured results of the proposed six-port phase correlator show the good agreement with simulation results. The performance of the six-port phase correlator shows the reflection loss below -20 dB in the dual-band. Also, the proposed six-port phase correlator got a good transmission characteristic within 1 dB gain difference and ${\pm}4.1^{\circ}$ phase imbalance, respectively.
