조직의 정보 자원에 대한 체계적인 관리의 필요성이 제기되면서, 조직들은 정보보안 투자를 높이고 있다. 정보 노출 사고는 단 한 건의 실수로 발생할 수 있으므로, 내부자까지 정보보안 준수가 요구된다. 본 연구는 내부의 보안 목표 수준을 높이는 것을 목적으로, 보안정책 목표 공유와 개인의 가치 인식, 그리고 적합성이 내부자의 준수 의도에 미치는 영향을 제시하였다. 조직 행동 및 보안 분야의 선행연구를 기반으로 연구 가설을 제시하였으며, 366건의 표본을 활용하여 가설 검정을 하였다. 결과적으로, 정보보안 정책 목표 공유가 조직원의 정책에 대한 가치 인식을 높여 준수 의도로 연계되는 것을 확인하였다. 또한, 개인-조직 적합성과 요구-능력 적합성이 준수 의도 관련 선행 요인들과 조절 효과를 가졌다. 연구 결과는 조직 환경과 조직원 가치, 그리고 적합성 관점에서 보안 목표 달성을 위한 조건을 제시하여, 조직의 보안 수준을 유지하는 방안을 제시한다.

We examined the mediating effect of the consistency of the values of organizational members on the relationship between the values of IT enterprise executives and organizational performance. Hypotheses 1, 2, and 3, which were set up to achieve the purpose of this study, were verified as follows. First, Hypothesis 1 proposed that the values of management will have a positive effect on organizational performance. Second, Hypothesis 2 proposed that the values of management are likely to have a positive effect on the consistency of the values of organizational members. Third, Hypothesis 3 proposed that the consistency of the values of organizational members will have a positive (+) influence on organizational performance. We found that the consistency of the values of organizational members has a positive (+) influence on organizational performance. Hypothesis 3 was adopted. Fourth, the consistency of the values of the organizational members proved that the organizations with high consistency of values performed well by mediating the values and organizational performance of management. In other words, according to the values of the management, we can improve an organization's sustainability management system by increasing the value of organizational performance and the values of organizational members. Therefore, we must establish plans that can be shared systematically and strategically about the values of management. In addition, the consistency of the values of organizational members has a direct or indirect influence on improving organizational performance. Therefore, we need to systematically derive and improve various factors that can increase the consistency of the values of organizational members in terms of strategic human resource management, such as organizational vision, core values, talent awards, selection process, and motivation. Therefore, the greatest significance of this study is in its theoretical and practical implications for increasing the sustainability management system by using the influence of the executives' can do to further improve the organizational performance.

Let f be a nonconstant meromorphic function of hyper order strictly less than 1, and let c be a nonzero finite complex number such that f(z + c) ≢ f(z). We prove that if ∆_cf = f(z + c) - f(z) and f share 0, ∞ CM and 1 IM, then ∆_cf = f. Our result generalizes and greatly improves the related results.

In this article, we prove some normality criteria for a family of meromorphic functions having zeros with some multiplicity. Our main result involves sharing of a holomorphic function by certain differential polynomials. Our results generalize some of the results of Fang and Zalcman [4] and Chen et al. [2] to a great extent.

We prove a uniqueness theorem of entire functions sharing an entire function of smaller order with their linear differential polynomials. The results in this paper improve the corresponding results given by Gundersen-Yang[4], Chang-Zhu[3], and others. Some examples are provided to show that the results in this paper are best possible.

We investigate the value distribution of difference-differential polynomials of entire and meromorphic functions, which can be gazed as the Hayman's Conjecture. And also we study the uniqueness and existence for sharing common value of difference-differential polynomials.

The purpose of this study is to gather baseline data on perceived housing values and satisfaction rates among consumers with the aim of using this information for future planning. Self-administered questionnaires were provided to 1000 university students from Gwangju and the Chonnam area from 2007 October 8th to 30th. The collected data was used to conduct comparative and descriptive statistical analysis: factor analysis, cluster analysis, t-test, $x^2-test$ and one-way ANOVA. The main findings are as follows: Firstly, in relation to perceived house values, students identified three factors as important: pursuit of convenience, disposition toward individuality-orientation and consciousness of others. The respondents regarded convenience as very important, especially in regard to one's safety, health and location of amenities. Secondly, cluster analysis based on perceived house value revealed passive and energetic types. Students in the energetic type exhibited a tendency to prefer convenience, independence, and consciousness of others. Finally in terms of housing satisfaction, the respondents identified four factors as important: house quality, neighborhood environment, local socio-psychological environment, and location. Housing satisfaction was higher among students who lived in large or new houses, shared the same house with their family, and had a room all to themselves. Accoding to these findings, university students important value safety, health and environmental-friendliness in a house and they find location important. Therefore, future houses should reflect these wants.

관광과 정보통신기술(Tourism and Information Communication Technology: ICT)의 결합은 관광산업 전체에 있어서도 ICT의 획기적인 변화를 야기하고 있다. e-관광(eTourism), 가상 관광(Virtual Tourism), 스마트 관광(Smart Tourism) 등의 다양한 용어들이 지난 10여 년간 등장하였지만, 스마트폰의 등장으로 인한 관광에서의 새로운 패러다임은 관광산업과 학계를 통틀어 충분히 논의된바 없다. 관광에서 ICT의 역할에 대한 기존문헌을 살펴보면 사용자 관점에서 관광객의 행동, 커뮤니티, 멀티미디어와 웹, 지능형 시스템, 스마트 관광의 5가지 주요흐름이 있는 것을 알 수 있다. 이에 본 연구는 스마트 관광의 개념을 기반으로 하여 스마트 관광 생태계에 대해 살펴보려고 한다. 본 연구에서 제시하는 스마트 관광 생태계(Smart Tourism Ecosystems)는 관광객, 유통채널, 공급채널, 정보, 지자체 등의 이해관계자들이 가치를 창출하는 개념이다. 이에 본 연구에서는 "공유가치 창출(Creating Shared Value)"이라는 관점에서 스마트 관광 생태계를 조망하고자 한다.

In this study, seven oligonucleotides primers were shown to generate the shared loci, specific loci, unique shared loci to each species and shared loci by the three species which could be obviously calculated. Euclidean genetic distances within- and between-species were also calculated by complete linkage method with the sustenance of the hierarchical dendrogram program Systat version 13. The genomic DNA isolated from herring (Clupea pallasii), Korean anchovy (Coilia nasus) and large-eyed herring (Harengula zunashi), respectively, in the Yellow Sea, were amplified several times by PCR reaction. The hierarchical dendrogram shows three chief branches: cluster 1 (PALLASII 01, 02, 03, 04, 06 and 07), cluster 2 (NASUS 08, 09, 10, 11, 12, 13 and 14), and cluster 3 (ZUNASHI 15, 16, 17, 18, 19, 20, 21 and PALLASII 05). In three clupeid species, the shortest genetic distance displaying significant molecular difference was between individual PALLASII no. 03 and PALLASII no. 02 (0.018). Individual no. 06 of PALLASII was most distantly related to NASUS no. 11 (genetic distance = 0.318). Individuals from herring (C. pallasii) species (0.920) exhibited higher bandsharing values than did individuals from Korean anchovy (C. nasus) species (0.872) (P<0.05). As a result, this PCR analysis generated on the genetic data displayed that the herring (C. pallasii) species was widely separated from Korean anchovy (C. nasus) species. Reversely, individuals of Korean anchovy (C. nasus) species were a little closely related to those of large-eyed herring (H. zunashi) species.

In this paper, we investigate the high order difference counterpart of $Br{\ddot{u}}ck^{\prime}s$ conjecture, and we prove one result that for a transcendental entire function f of finite order, which has a Borel exceptional function a whose order is less than one, if ${\Delta}^nf$ and f share one small function d other than a CM, then f must be form of $f(z)=a+ce^{{\beta}z}$, where c and ${\beta}$ are two nonzero constants such that $\frac{d-{\Delta}^na}{d-a}=(e^{\beta}-1)^n$. This result extends Chen's result from the case of ${\sigma}(d)$ < 1 to the general case of ${\sigma}(d)$ < ${\sigma}(f)$.
