  • 방통융합기술이 급격히 발전하고 이에 따른 서비스가 진화함에 따라 기존 미디어 환경은 실감화, 지능화, 연결화, 융합화 되는 스마트미디어 시대로 진입하면서 인간 생활에 혁신을 가져오고 있다. 기존 교육 환경이 학교의 틀에서 일방향의 형태로 지식을 전달하는 체제이지만, 4차 산업혁명시대에 진입하면서 사회는 굳은 조직과 질서의 틀을 벗어나 빠르게 다변화 하고 복잡해지는 사회 구조가 되어 가고 있어 지식을 쌓는 전통적인 교육보다는 당면한 문제를 주도적으로 해결할 수 있는 창의적 역량을 키워주어야 사회에서 적응할 수 있는 시대가 되었다. 따라서 이러한 스마트미디어를 교육 시스템에 활용하면 4차 산업혁명시대에 적합한 창의적 역량을 발휘할 수 있을 것이며 학습의 성취도, 만족도, 몰입도 등에서 상당한 효과를 얻을 수 있을 것이다. 본 논문은 현재와 미래의 융합미디어 환경에서 바람직한 교육정책을 제안하고자 한다.

  • It is necessary to assess and reap the benefits of integrating BP(Business Planning) and ISP(Information Systems Planning) in creating competitive advantage and ensuring superior financial performance. Securing and maintaining of integration between BP and ISP is frequently cited as a critical concern of IS managers. In general, however, BP and ISP are not integrated, and organization's strategy isn't supported effectively. Therefore, this paper identifies the current stage of BP-ISP integration of Korean insurance industry based on the survey and then reveals inhibiting factors and enabling factors for BP-ISP integration through the interview with IS managers of type 3 and type 4 companies. The results of this paper suggest factors to accomplish BP-ISP integration successfully for companies which are considering BP-ISP integration.

  • The influence of columnar dendirtes on the mechanical properties of Al-1% Cu alloys as unifirectionalloy solidified under the conditions of controlled crystal growth rate (R) and temperature gradient (G) was investigated. And the change of metallography and mechanical properties when unifirectionalloy solidified alloys and cast alloys were cold-rolled from 10% to 90% in reduction ratio was studied. The results are as follows: 1. The elongation and yield strength of unifirectionalloy solidified alloy are higher then those of cast alloy, but there is a little decrease in ultimate tensile strength. 2. The metallography and mechanical properties are changeable with the primary arm spacings when the unidirectionalloy solidified alloys were cold-rolled from 10% to 90% in reduction ratio. An alloy with larger primary arm spacings was easily changeable in metallography and mechanical properties when it was cold-rolled. 3. The tensile strength of transversely cold-rolled to 90% in reduction ratio was higher then that of longitudionalloy cold-rolled to 90% in reduction ratio. In the case, the fractorgraphs of fractured surface showed that the cast alloy and the unifirectionalloy solidified alloy was ductile-fractured, but the surface of transversely cold-rolled to 90% reduction of unidirection alloy solidified was slip plane qracture.

  • The operating temperature has been increased to improve the efficiency of gas turbine. The most advanced Gas turbine is operated at above $1,500^{\circ}C$. Improvement in material and cooling method permit hot gas path component to run at increased temperature. But, the repair of blades which are developed with advanced manufacture technique is difficult to use normal welding. Most of gas turbine blades are made of precipitation harden nickel base superalloy, which is very hard to weld. Therefore, the employment of welding filler on blade is solid solution nickel base superalloy(Hastelloy X, Inconel 617). In this study, Tensile test in high temperature was conducted on welded GTD111DS with GTD111 to evaluate effect of variation of pre, post treatment. The result of this study showed that the specimen was treated with optimum pre and post treatment(preweld HT($1200^{\circ}C$), Post treatment($1100^{\circ}C$ HIP, $1200^{\circ}C$ + $1100^{\circ}C$ + $800^{\circ}C$ HT) is mush superior.

  • The purposes of this paper examines the extant to which congruence in leader and follower rating of LMX quality is related to organizational commitment, and perceptions of organizational politics(POPs). A conceptual model is introduced that identifies four combinations of leader and follower LMX ratings of Cogliser et al.(2009): balanced/low LMX(low leader and follower LMX), balanced/high LMX(high leader and follower LMX), follower overestimation(low leader LMX/high follower LMX), follower underestimation(high leader LMX/low follower LMX). The summary of results based on a sample of 236 matched pairs of leaders and followers in KOREA is as follows: First, balanced/high LMX and follower overestimation were associated with relatively high levels of affective organizational commitment, and perceptions of organizational politics. However, follower underestimation and balanced/low LMX was related to low levels of follower outcomes. In particular, follower underestimation and balanced/low LMX were significantly different from balanced/high LMX and follower overestimation. Second, perceptions of organizational politics was negatively related to affective organizational commitment in the four LMX relationship types. Especially, the negative relationship between POPs and organizational commitment was stronger for people who are low as compared with high in LMX quality. Theoretical and practical implications of our findings as well as directions for future research are provided.

  • Previous research on work and life balance mainly focused on workers' passive acceptance of interferences rather than active management of them. However, workers can also actively manage boundaries to enhance work and life balance. To find ways to enhance work and life balance, especially in the context of Smart Work, factors having effects on the work/nonwork interferences and their relationships should be firstly investigated. The results show that in a work domain, both boundary strength at work and job autonomy negatively influence on the nonwork to work interferences; in a nonwork domain, both boundary strength at nonwork and autonomy have negative effects on the work to nonwork interferences.

  • In an effort to increase the thermoelectric figure of merit by reducing the thermal conductivity, the unidirectionally solidified n-type (Bi, Pb)-Te based alloys which form a $Bi_{2}Te_{3}-PbBi_{4}Te_{7}$eutectic lamellar structure were investigated with the microstructural control at various solidification conditions. PbBi_{4}Te_{7}$ lamellae were grown on cleavage plane(0001) of $Bi_{2}Te_{3}$ and the interlamellar spacing decreased from 10.4 $\mu \textrm{m}$to 3.2$\mu \textrm{m}$ with growth velocity variation from 1.4 \times 10^{-4}$cm/sec to $8.3 \times 10^{-4}$cm/sec. Seebeck coefficient was constant, $\mid$$\alpha$$\mid$=29 $\mu$ V/K regardless of growth direction, growth velocity and temperature gradient. Electrical conductivity showed a tendency to decrease slightly with growth velocity and it parallel to growth direction was about three times as large as perpendicular direction. The figures of merit were varied differently from Seebeck coefficients and electrical conductivities depending on the growth direction, growth velocity and temperature gradients. They showed the relative increase in case of perpendicular direction compared with parallel to growth direction. It is believed to be due to the reduction of the thermal conductivity according to decrease of the interlamellar spacing.

  • 사회의 근본적인 경제 구조가 농경사회에서 산업사회를 거쳐 정보사회로 전환되면서 인터넷 사용자와 인터넷에서의 마케팅 및 커뮤니케이션이 기하급수적으로 증가하고 있는 추세이다. 인터넷 매체의 빠른 확산과 인터넷 매체만이 갖는 특징 때문에 기존의 커뮤니케이션 환경과 양식, 기업의 활동양식, 나아가서는 개인의 라이프스타일이 크게 변모하고 있다. 통신과 네트워크 기술, 디지털 및 멀티미디어 기술의 발달에 힘입어 기존의 일방적이고 수동적인 정보전달 방식은 쌍방향적이고 능동적인 정보전달방식으로 바뀌어 가고 있다. 즉, 커뮤니케이션 주체간의 시간과 거리 공간의 벽이 없어지는가 하면 소비자의 정보수집, 구매, 의사 전달과 같은 행동양식도 크게 탈바꿈하고 있는 것이다. 뿐만 아니라 Interactive한 통신 기능을 기반으로 한 인터넷 광고는 마케팅이나 광고 캠페인에 대한 기업의 전통적 접근방식을 크게 변화시키고 있다. 본 연구에서는 이러한 정보화 시대의 인터넷 이용자들의 일반특성과 인터넷 사용 경향을 살펴보고 조직내에서 이뤄지는 인트라넷에서 실시되고 있는 배너광고(Banner Advertising)와 팝업창을 중심으로한 광고활용이 사내구성원의 효율적인 커뮤니케이션을 구축할 수 있는 방안을 모색하기 위한 개념적 모형을 제시하고자 한다.

  • The purpose of this study is to verify the moderating effect of perceived wellness climate in the relationship where work-family conflict influences individual engagement. For this, survey was executed on employees of 11 companies including IT, service, manufacturing and etc. After the survey was executed, statistical analysis was executed. This study executed validity test, credibility test, and Hierarchical Linear Regression. The analysis result is as follows. First, work-family (family-work) conflict gives negative (-) influence on individual engagement. Second, perceived wellness climate was marginally significant in the relationship between work-family conflict and individual engagement. And the control effect of perceived wellness climate in the relationship between family-work conflict and individual engagement was significant according to statistics. The conclusion states the implications and limitations of this study, and suggests directions on future studies.
