Up to the present, most of the previous works, related to the alignment of organizations, have been focused on the alignment between business and information technology. Also these works have been done with single element, e.g., view rather than with overall elements such as view, scope, and perspective for enterprise-wide integrated alignment. Meanwhile, an enterprise architecture is a blueprint that represents the structure of components of organizations and their interrelationships. Nowadays, many organizations attempt to make enterprise-wide alignment of business and information technology based on enterprise architecture. Unfortunately, the enterprise-wide alignment is still in a stage of not only conceptual level but also abstract level. Hence, this paper proposes a structured enterprise-wide alignment model to overcome the limitations of existing alignment models. We survey the existing works and propose the conceptual, the logical, and the physical models for enterprise-wide alignment which includes 3-dimensional elements such view, scope, and perspective based on enterprise architecture. Finally, we have shown that the proposed model is better than existing ones through comparing the characteristics of models.

기업의 성과관리와 성과평가 분야에서 성과지표의 분류는 조직의 내부 구성관계 즉, 수직적 (vertical) 구조(전사-본부-팀)와 수평적 (horizontal) 구조(본부와 본부 혹은 팀과 팀간)의 공유에 따라 구분될 수 있으나 기존 연구(Lipe & Salterio 2000, Dilla & Stcinbart 2005)에서는 공통지표와 고유지표라고 하는 수평적인 측면만이 고려되고 수직적인 측면은 고려되지 않았다는 한계가 있다. 조직의 성과가 향상되기 위해서는 하부조직이 전사 전략에 집중 할 필요가 있으며 이를 위하여 전사의 비전을 위한 전략목표달성에 기여한 정도를 측정하여 보상과 연계하는 것은 성과관리제도가 추구하는 기본 방향이며 도입목적이기도 하다. 그런데 선행 연구에서 밝혀지지 않은 조직구성 관계의 수직적 측면에서 전사지표의 정렬(Alignment)을 통한 공유와 할당(Cascading)된 지표의 가중치를 고려해 볼 때 고유지표는 재 정의하여 세분화 할 필요가 있다는 점이다. 즉, 특정 부서의 지표 중에는 전사 혹은 상위부서에 반영되어 공유하고 있는 고유지표(이하 공유지표)와 전사 혹은 상위부서에는 반영되지 않고 해당 부서만 독점하고 있는 순수한 고유지표(이하 고유지표$^{1}$)로 구분되어야 하며 공유지표와 고유지표의 분류에 따라 가중치 설정이 달라져야 한다는 주장이 그것이다. 따라서 본 연구의 목적은 조직이 성과를 공정하게 평가하고 하부조직이 전사전략에 집중하도록 하기 위해 공통지표와 고유지표를 사용하고 있는데(Dilla & Steinbart 2005), 고유지표를 공유지표와 고유지표로 재 정의하고 분류하여 관리 할 필요가 있다는 점과 각각의 지표 분류에 따라 가중치 설정에 차이가 있는지에 대한 유의성을 검증해 보고자 한다.

ROLAP(Relational Online Analytical Processing) is a process and methodology for a multidimensional data analysis that is essential to extract desired data and to derive value-added information from an enterprise data warehouse. In order to speed up query processing, most ROLAP systems pre-compute summary tables. This process is called 'cube generation' and it mostly involves intensive table sorting stages. (1) showed that it is much faster to generate ROLAP summary tables indirectly using a MOLAP(multidimensional OLAP) cube generation algorithm. In this paper, we present such an indirect ROLAP cube generation algorithm that is fast and scalable. High memory utilization is achieved by slicing the input fact table along one or more dimensions before generating summary tables. High speed is achieved by producing summary tables from their smallest parents. We showed the efficiency of our algorithm through experiments.

Glass/resin/glass laminate structures are used in the automobile, biological, and display industries. The sandwich structures are used in the micro/nanoimprint process to fabricate a variety of functional components and devices in fields such as display, optics, MEMS, and bioindustry. In the process, micrometer- or nanometer-scale patterns are transferred onto the substrate using UV curing resins. The demodling process has an important impact on productivity. In this study, we investigated the fracture behavior of glass/resin/glass laminates fabricated via UV curing. We performed measurements of the adhesion force and the interfacial energy between the mold and resin materials using the four-point flexural test. The bending-test measurements and the load-displacement curves of the laminates indicate that the fracture behavior is influenced by the interfacial energy between the mold and resin and the resin thickness.

Recently, there has been substantial interest in flexible and wearable devices whose properties and performances are close to conventional devices on hard substrates. Despite the advancement on flexible devices with organic semiconductors or carbon nanotube films, their performances are limited by the carrier scattering at the molecular to molecular or nanotube-to-nanotube junctions. Here in this study, we demonstrate on the vertical semiconductor crystal array embedded in flexible polymer matrix. Such structures can relieve the strain effectively, thereby accommodating large flexural deformation. To achieve such structure, we first established a low-temperature solution-phase synthesis of single crystalline 3D architectures consisting of epitaxially grown ZnO constituent crystals by position and growth direction controlled growth strategy. The ZnO vertical crystal array was integrated into a piece of polydimethylsiloxane (PDMS) substrate, which was then mechanically detached from the hard substrate to achieve the freestanding ZnO-polymer composite. In addition, the characteristics of transferred ZnO were confirmed by additional structural and photoluminescent measurements. The ZnO vertical crystal array embedded in PDMS was further employed as pressure sensor that exhibited an active response to the external pressure, by piezoelectric effect of ZnO crystal.

The purpose of this research is to investigate how an elementary English class is presented in terms of communicative properties using COLT and TALOS because previous studies mainly used COLT. A lack of TALOS has shown on the previous studies. Also, this study takes a close look into whether the English class is communicative or not communicative since previous studies criticized in that elementary English classes are not communicative. For the purposes of this research, COLT part B and TALOS low-inference were used to analyze one elementary English class which had won the grand prize at English class contest. The result of this study revealed that the class is communicative in terms of high quantity and quality of students utterances, high ratio of students' discourse initiation, students' unpredictable information giving utterances and extension of utterances. Findings from this study revealed the good elementary English class characteristics of this class: students' participation, focus on affective atmosphere, students-directed activities, and unconscious internalization of target expressions through repetition.

Since various methods to form well-aligned nano-/micro- patterns are underlying technologies to fabricate next generation wearable electronic devices, many efforts have been made to realize finer patterns in recent years. Among lots of patterning methods, the present invention includes a nano-transfer printing (n-TP) process which is advantageous in that a processing cost is low and high-resolution patterns can be formed within a short processing time. We successfully achieved pattern formation of highly ordered Pt lines with line-width of 250 nm, 500 nm, and $1{\mu}m$ on transparent and flexible substrates. In addition, we analyzed the durability of the patterns, showing excellent stability of line-shape even after a physical and repeated bending test of 500 times using a bending machine. As a result, it is expected that a n-TP process is very useful for forming various metal patterns, and it is also expected to be applied to wiring and interconnection technology of next generation flexible electronic devices.

For the past few decades, as part of efforts to protect the environment where fossil fuels, which have been a key energy resource for mankind, are becoming increasingly depleted and pollution due to industrial development, ecofriendly secondary batteries, hydrogen generating energy devices, energy storage systems, and many other new energy technologies are being developed. Among them, the lithium-ion battery (LIB) is considered to be a next-generation energy device suitable for application as a large-capacity battery and capable of industrial application due to its high energy density and long lifespan. However, considering the growing battery market such as eco-friendly electric vehicles and drones, it is expected that a large amount of battery waste will spill out from some point due to the end of life. In order to prepare for this situation, development of a process for recovering lithium and various valuable metals from waste batteries is required, and at the same time, a plan to recycle them is socially required. In this study, we introduce a nanoscale pattern transfer printing (NTP) process of Li2CO3, a representative anode material for lithium ion batteries, one of the strategic materials for recycling waste batteries. First, Li2CO3 powder was formed by pressing in a vacuum, and a 3-inch sputter target for very pure Li2CO3 thin film deposition was successfully produced through high-temperature sintering. The target was mounted on a sputtering device, and a well-ordered Li2CO3 line pattern with a width of 250 nm was successfully obtained on the Si substrate using the NTP process. In addition, based on the nTP method, the periodic Li2CO3 line patterns were formed on the surfaces of metal, glass, flexible polymer substrates, and even curved goggles. These results are expected to be applied to the thin films of various functional materials used in battery devices in the future, and is also expected to be particularly helpful in improving the performance of lithium-ion battery devices on various substrates.
