Recently the Korean Government is increasing investment and interest on railway in the transportation field as "low carbon and green growth" policy become main national development strategy. While railway competitiveness is weakening over the road from the inconvenient door-to-door and transfer system of railway, it is meaningful to review excellent railway transfer system of advanced countries and adapt their implications for Korea. Their transfer systems like Japan, Hongkong, France, U.K. and German can be categorized in this research as kinds of transfer & connectivity system and transfer facility & flow planning, and, as a result, their implications can be concluded. Also, analyzing transfer system of Korea's main stations and reviewing the difference between Korea and other countries, this paper suggests main principles and directions of urban planning, alignment of rail line, partnership of project stakeholder in the establishment of transfer system in the railway station in the future.

The thrust in this paper is to discuss the dimensions of executive scanning process (ESP) that support continuous scanning activities by executives. Executive scanning is especially important for the healthcare organizations in these days since the environment they are faced with is extremely complex and dynamic. While much has been written about ESP, two important aspects have been underemphasized in the past. The first is a link to the strategic management process (SMP) or the issue of strategy-scanning alignment. The second is a feedback loop to verify the quality of information generated through scanning process. This paper discusses the improved ESP by adding these two features.

The objective of this research is to identify a web portal's specific functions and layouts that are aligned with personality trait of an individual internet user. This first stage of the overall research project intends to check whether the research instrument, namely the NEO Five Factors Inventory (NEO-FFI), is applicable to assess the personality traits of Thai internet users. Based on these personality traits, text-based description of functions/layouts of a web portal was developed and given to professional designers to mock up example web portal pages. These web portal pages were in alignment with individual personality traits. Rating data on the functions/layouts corresponding to individual personality traits were collected from an online survey of 207 Thai internet users. Results showed that respondents gave more consistent rating to the functions/layouts close to their individual personality traits identified in the text-based descriptions than in the mocked-up web portal pages.

A Systematic Wealth Management Framework (SWMF) was developed as a private banking management tool to enable more integrative personal finance management of personal wealth. It is a reference model that provides an unified framework for development, operation, and management and makes provision for personal financial services in today's complex financial environment. This study suggested some practical results from banks and insurance companies that have established SWMF as the differentiation business strategy for wealthy customers. The focus of this manuscript is on capturing the methodological approach most financial institutions in Korea adopted to execute new e-finance planning and implementation based on the SWMF. The alignment between the wealth management business goals and information system architecture at an organization constitutes the main theoretical basis of the study. Relevant discussions are made on the wealth management framework as a general business model for financial industry, on the functional relationship between new information systems and business organizations. Finally, lessons learned from the SWMF implementation are discussed.

This research explores how the success of smart factory adoption is influenced by firm's dynamic capability. This research describes the underlying processes on how organizations manipulate or adapt organizational elements harmoniously to implement smart factory successfully. Although understanding of these processes is essential to many researchers and practitioners in the field, the information system research literature contains very few examples of this type. The research is conducted in the following sequence: first, the concept of dynamic capability is presented followed by research methodology; and then the analyses of case data are presented followed by discussions and future directions. The results of this research show that the firms with higher dynamic capability adopted smart factory more easily through alignment of various organizational elements.

Purpose: This study examined two trunk strategies - medio-lateral ramp and anterior-posterior ram - and their effects on pelvis and trunk movements, providing basic material for safe ramp utilization. Methods: The present study included 20 asymptomatic males recruited from a local university. Participants were asked to stand with their feet shoulder-width apart. Their dorsal side faced the camera, and measurements were performed while standing in a neutral double stance, one leg stance, $15^{\circ}$ of medial and lateral ramp, and $15^{\circ}$ of anterior and posterior ramp. Participants were allowed to practice for 3 minutes, and each participant had a 30 seconds rest between the two ramp conditions. One-way repeated measures analysis of variance was used to determine the effects the ramp conditions on spinal alignment. In all analyses, p<0.05 was used to indicate statistical significance. Results: The trunk-inclination angle on the posterior ramp was significantly lower than that of the double stance position (p<0.05). The trunk imbalance angle was significantly higher on the medial ramp, than that on the double stance position (p<0.05). The pelvic position and pelvic torsion angles were significantly higher in the medial, lateral, and anterior ramp positions than that of the double stance position (p<0.05). The pelvic rotation angles on the medial, lateral, and anterior ramps were significantly lower than that of the double stance position (p<0.05). Conclusion: These findings suggest that when people are exposed to the same form of ramp for an extended period, posture modifications may be triggered.

이동통신 서비스 제공을 위한 필수적인 요소자원인 주파수는 그 대역의 특성에 따라 사업자의 서비스 제공 경쟁력을 크게 좌우할 수 있다. 이에 본 연구에서는 주파수 자원에서도 상대적으로 우수한 특성을 가져 서비스 제공 상 우위를 가지며 경쟁정책적인 관리가 필요한 이동통신 주파수 대역을 핵심 우량대역이라고 정의한다. 이를 위해서 기술적 특성이 아닌 시장상황을 고려한 주파수의 활용성 및 경제적 효율성 측면의 4가지 기준(글로벌소싱 및 호환성, 비용-효율성, 주파수 활용 경험, 현재의 활용가능성)을 수립하였다. 이러한 기준들을 순차적으로 적용하여, 우량 주파수 대역 후보들을 추출하고 단계적인 평가기준을 통해서 현재시점에서의 최종적인 핵심 우량대역을 식별하였다. 또한 이러한 결과는 기술의 발전과 시간의 흐름에 따라 변화하는 특성을 보여준다. 본 연구의 분석결과는 이동통신 주파수에 대한 경쟁관리정책뿐만 아니라 할당정책에도 논리적 근거로 활용될 수 있는 실용적 의의를 지닌다.

본 논문에서는 3-Cell 간섭 환경에서의 하향링크 MU-MIMO를 위한 간섭 공간 재활용 기술 (ISR)과 그 적용방안을 제시한다. 멀티 셀 간섭환경의 셀 경계 사용자들의 안정적인 통신을 위해서는 효율적인 간섭 관리가 필요하다. 하지만 셀 중심부의 사용자들의 경우 간섭의 영향을 적게 받으며 적은 전송 전력으로도 안정적인 통신이 가능하다. 본 논문에서는 셀 경계 사용자의 간섭 공간을 재사용하여 셀 중심부 사용자에게 서비스를 제공하는 ISR 기반 전송 신호 설계 방법을 제시한다. ISR 방식은 간섭정렬(IA)과 결합된 부분적 주파수 재활용 (fractional frequency reuse : FFR) 방식과 비교하여 볼 때 셀 중심 사용자와 셀 경계 사용자에 대한 scheduling에 따라 전체 네트워크 데이터 전송용량 측면에서 20%의 성능 향상을 보이며 또한 셀 중심 사용자의 서비스 품질 (QoS) 요구조건이 고정되어 있는 경우 ISR 방식에 의해 기지국에서의 전송 신호 벡터를 설계함으로서 셀 경계 사용자의 데이터 전송 용량을 증가시킬 수 있다.

Northeast Asia has a multi-layered security structure within which major economic and military powers both confront one another and cooperate at the same time. Major regional powers maintain mutually cooperative activities in the economic sphere while competing one another in order to secure a dominant position in the politico-military arena. The multifarious threats, posed by the North Korea's nuclear development, territorial disputes, and maritime demarcation line issues demonstrate that Northeast Asia suffers more from military conflicts and strifes than any other region in the world. Specifically, major maritime security threats include North Korea's nuclear proliferation and missile launching problems as well as military provocations nearby the Northern Limit Line(NLL) as witnessed in the Cheonan naval ship and Yeonpyong incidents. The ROK Navy has been supplementing its firm military readiness posture in consideration of North Korea's threats on the NLL. It has performed superb roles in defending the nation and establishing the Navy advanced and best picked. It also has been conducive to defend the nation from external military threats and invasion, secure the sea lanes of communications, and establish regional stability and world peace. In order to effectively cope with the strategic environment and future warfares, the ROK Navy needs to shift its military structure to one that is more information and technology intensive. In addition, it should consolidate the ROK-US alliance and extend military cooperative measures with neighboring countries in the Asia-Pacific region. Evolved steadily for the last 60 years, the ROK-US alliance format has contributed to peace and security on the Korean peninsula and in the Northeast Asian region. In conclusion, this manuscript contends that the ROK Navy should strive for the establishment of the following: (1) Construction of Jeju Naval Base; (2) Strategic Navy Equipped with War Deterrence Capabilities; (3) Korean-type of System of Systems; (4) Structure, Budget and Human Resources of the Naval Forces Similar to the Advanced Countries; and (5) Strategic Maritime Alliance and Alignment System as well as Domestic Governance Network for the Naval Families.
