This Qualitative case study focused on the National Pilot Project to make family-friendly communities. We examined the basic model of the family-friendly community proposed by the Ministry of Gender Equality and Family. One of the three local communities selected as family friendly models was chosen for observation and in-depth interview for its residents. The official performance report shows this project's process, results and future tasks. From the in-depth interview data, we defined the project's characteristics as the government and private sectors collaboration, model transformation from the original family friendly model to the production model, and we found some conflicts among residents upon financial issues and business items. The most important task is the vitalization of the community corporate body to realize this project's performance through these three years. And this study implicates to elaborate the rural family-friendly community model focused on income creating community redesign, different from the urban model focused on caring.

Nurses in a children's hospital have to meet a special condition with their younger patients who need continuous supervision and cares. The planning of the ward where the nurse as well as the patient and his/her caregivers stay all day long should cover all the users need. This study focused on the nurse's need for the ward in children's hospital. The nurse stay longer than any users in hospital and their treatment have to be based on deep understanding of their patients. The survey research followed the literature review on the children's hospital and the nurses' task and behavior. 119 nurses answered the structural questionnaire and their answers were analyzed using the statistical process such as basic descriptive statistics, ANOVA, and actor analysis. Results and conclusions are as follows. (1) The subjects least satisfied with the accessibility for the children and the nature-and child-friendly design features among physical environment design factors of the hospital. (2) The Subject regarded the patients' room to a private place of the patients and their caregivers not to the work places. (3) The design factors of the nursing station were classified into four: the functionality-, the privacy-, the supervision-and the restfulness-factor. The functionality and supervision factor were highly required as a workplace, the privacy factor between the patients, their caregivers and subject were also represented high score, but the restfulness factor were least required.

Equipped with the advantages of flexible access control and fine-grained authentication, attribute based signcryption is diffusely designed for security preservation in many scenarios. However, realizing efficient key evolution and reducing the calculation costs are two challenges which should be given full consideration in attribute based cryptosystem. In this paper, we present a key-policy attribute based signcryption scheme (KP-ABSC) with delegated computation and efficient key updating. In our scheme, an access structure is embedded into user's private key, while ciphertexts corresponds a target attribute set. Only the two are matched can a user decrypt and verify the ciphertexts. When the access privileges have to be altered or key exposure happens, the system will evolve into the next time slice to preserve the forward security. What's more, data receivers can delegate most of the de-signcryption task to data server, which can reduce the calculation on client's side. By performance analysis, our scheme is shown to be secure and more efficient, which makes it a promising method for data protection in data outsourcing systems.

IPv6는 기존 IPv4의 문제점인 주소 고갈 문제를 근본적으로 해결하기 위해 IETF(Internet Engineering Task Force)에서 제안한 프로토콜이다. 그러나 IPv4를 한 순간에 IPv6로 대체하는 것이 불가능하기 때문에 IPv4와 IPv6간의 호환 및 연동을 위해 듀얼스택(dual stack), 터널링(tunneling), 프로토콜 변환(protocol translation) 등 많은 IPv4-to-IPv6 transition 메커니즘들이 고려되고 있다. 이러한 프로토콜 진화 방안들은 각 방식에 따라 최소한 한 개 이상의 많은 공인 IPv4 주소를 필요로 하며 IPv4 주소가 부족한 현재 상황에서 IPv6 네트워크와의 연동에 않은 어려움이 따르게 된다. 본 논문에서는 공인 IPv4 주소 부족 문제와 네트워크 보안의 필요성에 의해, IPv4 사설 네트워크에서 공인 IPv4주소로 이루어진 네트워크(인터넷)와 IPv6 네트워크의 연동을 위해 단지 하나의 공인 IP 주소를 이용하여 네트워크간의 연동을 지원하는 통합 연동기를 설계한다.

Advanced Manufacturing Technology(AMT), a comprehensive collection of new technologies for the efficiency and flexibility of manufacturing systems has received a growing attention recently, AMT consists of various industrial and technological components, homogeneous in some aspects while heterogeneous in others. Thus, it is difficult but necessary task to construct a classification framework in which the relationship among individual technologies are depicted in a meaningful fashion. In this, paper, we propose a hierarchical framework in which the objective and criteria of classification are decomposed into three level: industrialization, development and application of AMT. At the first and highest level, the main interest is to "industrialize" AMT. The major actors at this level are policy makers(public sector) and top management(private sector) and the primary classification criterion is the interrelationship between industry and technology. At the middle level exist system engineers whose main objective is to "develop" new technologies and/or systematize individual technologies. At the final and bottom level, shop floor managers need to "apply" AMT in order to enhance the efficiency and flexibility of manufacturing process. It should be stressed that, as a whole, the above three levels should be interactively linked to that each level contributes to the balanced development of AMT.

Torque ripple minimization without decrease in average torque is a vital attribute in the design of Synchronous Reluctance (SynRel) motor. As the design of SynRel motor is an arduous task, which encompasses many design variables, this work first analyses the significance of the effect of varying the geometrical parameters on average torque and torque ripple and then proposes an extensive optimization procedure to obtain configurations with improved average torque and minimized torque ripple. A hardware prototype is fabricated and tested. The Finite Element Analysis (FEA) software tool used for validating the test results is MagNet 7.6.0.8. Multi Objective Particle Swarm Optimization (MOPSO) is used to determine the various designs meeting the requirements of reduced torque ripple and improved torque performance. The results indicate the efficacy of the proposed methodology and substantiate the utilization of MOPSO as a significant tool for solving design problems related to SynRel motor.

This research aims to analyze the external activities of local governments in South Korea from the perspective of the developing trends in city diplomacy, contrary to the conventional and narrow concept regarding local government's international exchange and cooperation as a public diplomacy. In detail, this research intends to illustrate the following: first, to differentiate South Korean local governments' growing commitment to international affairs from public diplomacy; second, to highlight the integration of public diplomacy with other forms of diplomacy within the framework of city diplomacy. This research argues that city diplomacy in South Korea has gradually shown the following three trends and characteristics. First, South Korean local governments have recognized the importance of participating in multilateral diplomacy via city networks to find compelling solutions to non-traditional and transnational security threats. They perceive this external activity as an opportunity for policy sharing and problem-solving with foreign partners. Second, local governments in South Korea have been fostering various ways to institutionalize their involvement in foreign affairs and organizations, such as amendments to related laws and the launching of task forces, to pursue so-called sustainable and systematic international exchange and cooperation. Lastly, South Korean local governments have constructed multiple channels and multilevel governance in the form of public-private partnerships to enhance policy expertise and cope with diverse agendas.

In recent years, retinal disorders have become a serious health concern. Retinal disorders develop slowly and without obvious signs. To avoid vision deterioration, early detection and treatment are critical. Optical coherence tomography (OCT) is a non-invasive and non-contact medical imaging technique used to acquire informative and high-resolution image of retinal area and underlying layers. Disease signs are difficult to detect because OCT images have many areas which are not related to any disease. In this paper, we present a deep learning-based method to perform multi-label classification on a long-tailed OCT dataset. Our method first extracts the region of interest and then performs the classification task. We achieve 98% accuracy, 92% sensitivity, and 99% specificity on our private OCT dataset. Using the heatmap generated from trained convolutional neural network, our method is more robust and explainable than previous approaches because it focuses on areas that contain disease signs.

It is the time of the Korean Wave booming throughout the world, placing Korean culture in the center of the world and its added value is unaccountable. At this prosperity, the preserving of the archetype of Korean dancing and digital contents making is becoming a task not only for the government but also for the private sector because culture industry has enormous added values. To achieve such goals, contents development is an urgent matter but establishing the value of the archetype of Korean traditional dancing must have priority. The public has to take an active role in rediscovering the values of traditional culture, and as the representative of Korean identity traditional dancing must be the object of a systematic art policy. This study will review the current status of 'digital contents program of the archetype of culture' for traditional dancing and will reconsider the modern value of preserving the archetype of culture to make a suggestion to the direction of culture art policies in the near future. The study acknowledged the lack of technical personnel majoring in the archetype of traditional dancing and the need of reviewing the credibility of historical research procedures. Even with the studies by industry-university collaboration and positioning of specialists, effective policies that will form the foundation for private firms to train personnels is in urgent need. In other words, training personnels, allocation of resource, securing funds, policies promoting collaboration between private and individual businesses, and the commercial recognition at private firms are still far from establishing. This is due to the fact that archetype of culture is not a business that creates revenue immediately, therefore the recognition of traditional dancing as an investable item by business-oriented firms or movements are difficult to find. To overcome such situation, software oriented policies that establish open communication and sharing with the public should be done at first rather than the quantity oriented hardware policies of contents development. Through this process the public can change the attitude on traditional dancing and traditional dancing could be newly recognized as a creative repository of culture and as public businesses giving birth to economic value.
