As Korea's global IT sourcing is sluggish and supply of qualified IT personnel does not meet the demand, IT developers currently do not worry about their job security. The sluggish global sourcing is attributed to the lack of system design and analysis skills as well as lack of communication skills of IT personnel. Most of big Korean IT service firms operate in captive market. This is also attributed to the cause of the sluggish global sourcing. Some IT managers, especially in global IT service firms, concerned about the negative long term effect of the sluggish global sourcing on competitiveness and human infra capability of Korea's IT service industry. Managers in IT service firms expect skill requirement changes in the future when global sourcing becomes active. The skills and knowledge that they wish to retain in-house is business knowledge, system analysis and design knowledge, customer relation management skills, project management skills and industry knowledge. The jobs with the above knowledge usually involve customers.

The Harmonized System comprises about 5,000 commodity groups; each identified by a six digit code, arranged in a legal and logical structure and is supported by well-defined rules to achieve uniform classification. This study reviews the appropriateness of Korea Customs Service and Tax Tribunal's customs classification decisions concerning the interpretation and application of the Harmonized System for certain ITA goods. Korea Customs Service had classified arbitrary and had not applied in dubio pro reo principle. This paper finds that 57% of Korea Customs Service's classification decisions have erred. Korea government need to take measures to secure uniform interpretation of the HS and its periodic updating in light of developments in technology and changes in trade patterns. This paper suggest to amend customs law and regulation concerning classification committee.

This study attempts to examine the importance of social capital in customer service organizations and clarifies how translates into organizational performance through knowledge management activities. A survey was conducted with the customer service employees, and 256 questionnaires were used for an empirical analysis with smart partial least squares (PLS). The analysis found that relational capital had a positive effect on both the knowledge management components of knowledge sharing and knowledge conversion, while structural capital significantly influenced knowledge sharing. In addition, human capital positively affected knowledge conversion. Both knowledge sharing and knowledge conversion significantly influenced organizational performance. This study proposed a conceptual framework of social capital that influences organizational performance mediated by an organization's knowledge management activities. Based on the results, we suggest practical guidelines for managing social capital and recommend areas of improvement for customer organization's managers and employees.

This paper empirically examines the relationship between outward foreign direct investment (OFDI) of Korean manufacturing firms and the servicification of domestic employment using a firm-level panel data. In this study, considering the issue of low productivity in the Korean service sector, we categorize service employment into core and non-core services and investigate their relationship with OFDI using the firm-fixed effects model. The empirical results show that the share of core service employment exhibits a positive correlation with the extensive OFDI. On the other hand, the share of non-core service employment, which is expected to generate relatively low value-added, does not show a significant relationship with the extensive OFDI. When we divide the samples based on host countries and the type of subsidiaries, the impact on servicification varies depending on the technological capabilities of host countries and their participation in global value chains. Our study suggests that Korean manufacturing firm's internationalization strategies may facilitate a transition from labor-intensive employment, like the cases in advanced countries, to technology-intensive employment through OFDI and other means.

In recent years, technology is rapidly changing to support new service consumption and distribution models in multimedia service systems and hybrid delivery of media services is a key factor for enabling next generation multimedia services. This phenomenon can lead to rapidly increasing network traffic and ultimately has a direct and aggravating effect on the user's quality of service (QOS). To address the issue, we propose a novel system architecture to provide smart hybrid media services efficiently. The architecture is designed to apply the software-defined networking (SDN) method, detect changes in traffic, and combine the data, including user data, service features, and computation node status, to provide a service schedule that is suitable for the current state. To this end, the proposed architecture is based on 2-level scheduling, where Level-1 scheduling is responsible for the best network path and a computation node for processing the user request, whereas Level-2 scheduling deals with individual service requests that arrived at the computation node. This paper describes the overall concept of the architecture, as well as the functions of each component. In addition, this paper describes potential scenarios that demonstrate how this architecture could provide services more efficiently than current media-service architectures.

There's an opinion that it may be a combination of change of values and social economic factors that caused low fertility of Korean society. This study intends to analyze actual conditions of family children values and gender role centered on university students in a marriageable age so draw a policy implication for overcoming low fertility. Main findings of this study are like following. First, as for analysis of childbirth intention shows average score of $3.35{\pm}1.142$ presented sex distinction that men have a higher tendency to women. Second, in gender role attitudes, it shows that gender role related on women's social activities($2.06{\pm}0.739$), traditional gender role in family($2.41{\pm}0.789$) influence on childbirth intention (p<0.001). Third, in family children values indicates moderate scores($2.95{\pm}0.648$) that son's position in family ($2.33{\pm}0.911$), relation between children and parents($2.80{\pm}1.050$), individual's position in family($3.56{\pm}0.671$) influence on childbirth intention(p<0.000) in the traditional values. Measures against low fertility will prove effective when family values are established favorable to marriage, childbirth, rearing, gender equality is settled in a society as a whole and related systems.

The objectives of this research are 1) to identify different motivation of choice for each National University hospitals 2) to examine the factors influencing the patients' satisfaction, 3) and to investigate that the patients' satisfaction effects the hospital re-choice and recommendation on seven National University's hospitals. The data for this analysis were collected by questionnaire survey. Totally 852 interviews were conducted. The major statistical methods used for the analysis are paired t-test, factor analysis, x2-test, and multiple regression. We find that satisfaction level is a function of not only the quality of medical service but also non-medical service. The main results of research are follows: 1) The most important factor of hospital choices is 'the trust and fame as National University hospitals'; 2) Overall satisfaction of inpatients is turned to be influenced by the doctor's services, nurse's services, environment, and convenience. And overall satisfaction of outpatients is also found to be influenced by the waiting time for lab test; 3) Highly satisfied patients preferred to revisit and to recommend to others.

처음 스마트폰이 출시된 이후 다양한 모바일 디바이스들의 발전으로 모바일 트래픽의 사용이 폭발적으로 증가하고 있다. 특히 개인 방송, TV 콘텐츠를 지원하는 OTT(On-The-Top) 서비스가 발전하고 이를 이용하는 사용자가 많아질수록 높은 전송률을 요구하는 영상 트래픽이 증가하게 되어 망의 과부화가 발생할 수밖에 없다. 본 논문에서는 D2D(Device-to-Device) 통신과 위치기반 서비스를 이용하여, OTT 서비스 트래픽에서 발생하는 망 과부화를 해결할 수 있는 방안을 제시하였다. 무선통신망의 OTT 서비스 트래픽을 효과적으로 처리하기 위하여 기존 셀룰러 네트워크에 위치기반 서비스와 D2D 단말 관리를 수행할 수 있는 D2DS(D2D Server)와 LCS(Location Server) 기능블록을 추가하였다. D2DS와 LCS를 통해 OTT 서비스에서 콘텐츠 제공자나 수신자의 역할을 하는 사용자에게 위치기반 D2D를 제공할 수 있는 절차를 추가로 제안하였다.

IPv6 환경에서는 인터넷 전화, 주문형 비디오 및 다자간의 대용량 파일 교환 서비스 등이 더욱 증가될 것이므로 단-대-단(End-to-End)기반의 엄격한 품질 보장 및 상대적으로 사용을 억제할 수 있는 차등화된 품질 제어 방안이 동시에 요구된다. 본 논문은 IPv6망에서 트래픽을 플로우 단위로 식별하고 IPv6 홉-바이-홉 옵션 헤더 내의 QoS 정보를 이용하여 멀티서비스의 QoS 개선을 위한 플로우 기반의 제어 방안을 제시한다. 플로우 제어 대상은 플로우 레이블 값을 이용하는 Non-default QoS 트래픽 뿐만 아니라 최선형 및 암호화 트래픽으로 확대 적용한다. 이를 통해 실시간 서비스에 대한 보장성은 강화하고 불필요하게 망 자원을 남용하는 플로우는 효과적으로 제어한다. 또한, 기존 망 자원의 최소 변경과 통신사업자의 백본망 현황을 반영하여 플로우와 MPLS간 매핑 방안을 제시한다. 시뮬레이션 결과에서는 제안하는 플로우 품질 제어 방안이 실시간 서비스에 대한 QoS 제공 및 백본 자원의 활용 측면에서 효율적임을 확인한다.

This paper focuses on the scheduling problem with the objective of maximizing system throughput, while guaranteeing long-term quality of service (QoS) constraints for non-realtime data users and short-term QoS constraints for realtime multimedia users in multiclass service high-speed uplink packet access (HSUPA) systems. After studying the feasible rate region for multiclass service HSUPA systems, we formulate this scheduling problem and propose a multi-constraints HSUPA opportunistic scheduling (MHOS) algorithm to solve this problem. The MHOS algorithm selects the optimal subset of users for transmission at each time slot to maximize system throughput, while guaranteeing the different constraints. The selection is made according to channel condition, feasible rate region, and user weights, which are adjusted by stochastic approximation algorithms to guarantee the different QoS constraints at different time scales. Simulation results show that the proposed MHOS algorithm guarantees QoS constraints, and achieves high system throughput.
