이 논의는 2015년 2학기 교양교육 수업시간에 34명의 대학생을 대상으로 '사진일기와 그림동화를 활용한 자기발견 진로프로그램'을 시행한 수업결과물을 제시한 것이다. 즉 취업이라는 관문 앞에 진로결정을 해야 하는 문제에 당면한 대학생이 취업 정보를 통해 진로를 결정하기 전에 먼저 자신의 특성을 제대로 알고 그에 따라 원하거나 할 수 있는 일을 찾을 수 있게 안내해주는 것이다. 이때 인간의 본질적인 삶을 다루는 문학이 그 역할을 담당할 수 있다고 기대한 것이다. 그 결과 대학생은 1차 2차 3차 자기발견 과정을 통해 자신이 어떤 유형인지 알고 '잘못 알았던 나', '몰랐던 나', '기존에 알았던 나'에 대한 특성을 인지하면서 자연스럽게 진로탐색까지 도달할 수 있었다. 따라서 '문학'을 활용한 자기발견 진로프로그램은 아직 초보단계에 있지만 새롭게 대학생의 진로탐색을 가능하게 했다는 것을 밝혔다.

The Web Services infrastructure is a distributed computing environment for service-sharing. Mechanisms for Web services Discovery proposed so far have assumed a centralized and peer-to-peer (P2P) registry. A discovery service with centralized architecture, such as UDDI, restricts the scalability of this environment, induces performance bottleneck and may result in single points of failure. A discovery service with P2P architecture enables a scalable and an efficient ubiquities web service discovery service that needs to be run in self-organized fashions. In this paper, we propose an autonomic -interleaving Registry Overlay Network (RgON) that enables web-services' providers/consumers to publish/discover services' advertisements, WSDL documents. The RgON, doubtless empowers consumers to discover web services associated with these advertisements within constant D logical hops over constant K physical hops with reasonable storage and bandwidth utilization as shown through simulation.

The development of web-aware knowledge discovery system has received a great deal of attention in recent years. It plays a key-enabling role for competitive businesses in the E-commerce era. One of the challenges in developing web-aware knowledge discovery systems is to integrate and coordinate and coordinate existing standalone or legacy knowledge discovery applications in a seamless manner, so that cost-effective systems can be developed without the need of costly proprietary products. In this paper, we present an approach for developing a framework of web-aware interoperable knowledge discovery system to achieve this purpose. This approach applies RMI and high-level code wrapper of Java distributed object computing to address the issues of interoperability in heterogeneous environments, which includes programming language, platform, and visual object model. The effectiveness of the proposed framework is demonstrated through the integration and extension of the two well-known standalone knowledge discovery tools, SOM_PAK and Nenet. It confirms that a variety of interoperable knowledge discovery systems can be constructed efficiently on the basis of the framework to meet various requirements of knowledge discovery tasks.

Knowledge discovery in databases(KDD) is the process for extracting valid, novel, potentially useful and understandable knowledge form real data. There are many academic and industrial activities with new technologies and application areas. Particularly, data mining is the core step in the KDD process, consisting of many algorithms to perform clustering, pattern recognition and rule induction functions. The main goal of these algorithms is prediction and description. Prediction means the assessment of unknown variables. Description is concerned with providing understandable results in a compatible format to human users. We introduce an efficient data mining algorithm considering predictive and descriptive capability. Reasonable pattern is derived from real world data by a revised neural network model and a proposed fuzzy rule extraction technique is applied to obtain understandable knowledge. The proposed neural network model is a hierarchical self-organizing system. The rule base is compatible to decision makers perception because the generated fuzzy rule set reflects the human information process. Results from real world application are analyzed to evaluate the system\`s performance.

Objective: This study analyzed the compliance situation of class rules for 3-year olds in the Wisdom class at Sarang kindergarten. Methods: Research participants were composed of 17 young children and two teachers in the wisdom class for 3-year-olds and data collection and analysis were conducted by participant observation using the qualitative method. Results: Research results were as follows. The compliance situation of class rules included compliance, violation, and among compliance and violation. First, compliance was divided into compliance with assistance and self compliance. Compliance with assistance is for young children to follow the rules under the guidance, help, and instructions of teachers. Self compliance is for children to understand and follow the rules themselves. Second, Between compliance and violation is conflict of the rules created by different standards of class rules. Third, depending on who found the violation, violation was classified into teacher discovery, peer discovery, and acquiescence. The teacher discovery led to teacher guidance and teacher acquiescence, The peer discovery led to peer notification, peer resistance, peer punishment, and peer acquiescence. Conclusion/Implications: By looking at the compliance situation of class rules for three-year-olds, the educational implications of how to guide class rules were obtained for children.

This qualitative nursing research used a hermeneutic phenomenological approach to discovery of meaning of the nursing students' clinical experience in junior colleges. Data collecting was utilized by in- depth face-to-face interviews of 10 sophomores who were participating in their first clinical experience. The following themes of the experience emerged. 1) The first step of fear (fear, being embarrassed) 2) Rhythmical patterning of theory and practice(disappointment of nurses, recognition of the gap between the theory and practice, the conflict between medical doctors and nurses, trouble with the students from other colleges, confusion from nurses' educational and noneducational attitudes, burden of responsibility for nurses' jobs, and the tiresome nature of repeated practice) 3) Discovery of changing self, awareness of self-expansion (awareness of professional nurses' roles, formation of self-confidence, changing of one's state of mind) From this study essential theme of clinical experience of nursing student's was identified, and continuous efforts to establish better adaptation of nursing students to clinical practice are required.

Accounts from therapeutic culture seem often to associate the selfish, or at least self-centered quest for self-fulfillment with individual choice or satisfaction, self-expression, expressive individualism, and emotionalism. These associations point to the downside of therapy as they present it as constituting a culture of narcissism, selfishness, or irresponsibility. While some of these characterizations contain useful insights, they overlook what are maybe some of the most important features of a therapeutic outlook. This paper aims to reveal that the therapeutic imperative is not so much geared towards the realization of self-fulfillment, as it is the promotion of self-limitation. Therapeutic culture tends to posit the self in a fragile and feeble form and insist that the management of life requires the continuous intervention of therapeutic expertise. Because of this, the elevated concern with the self is underpinned by anxiety, pain, suffering, and survival, rather than seen as a positive vision of realizing the human potential. Therapeutic culture has in this way helped to construct a diminished sense of self by which one is seen as suffering from an emotional deficit and vulnerability. This paper demonstrates this downside of therapeutic culture concerning self-limitation and the sense of a diminished self by examining popular "misery memoirs." Misery memoirs are widely consumed by the general public, therefore tend to be treated by contemporary therapeutic culture as a gospel on the therapeutic ideal for self-fulfillment and self-discovery. This is, despite the existence of hidden evidence to the contrary, because of their redemptive, happy endings that show individuals overcoming difficult trials such as child abuse, incestuous rape, and domestic violence. Individual self-fulfillment and self-discovery in such stories are not achieved through the active agency of the subject but through the passive endurance of pathological symptoms and with the aid of expertise and outside support. Therefore, such stories put victims in the limited position.

무선 애드혹 네트워크에서 이웃 탐색 과정은 네트워크를 초기화하는데 먼저 수행되어야 하고, 라우팅 알고리즘이나 토폴로지 컨트롤, 그리고 MAC 계층 설계를 위해서도 반드시 필요한 과정이므로 효율적인 분산적 이웃 탐색방법 설계가 필수적이다. 본 논문에서는 확률적 이웃 탐색 기법 (PND: Probabilistic neighbor discovery)을 제안한다. 제안한 기법에서는 MIMD (Multiplicative-increase, multiplicative-decrease) 정책을 통해 광고 메시지의 전송확률을 제어함으로써 이웃 탐색에 소요되는 시간을 줄이는 것이 가능하다. 더불어 임의의 기기가 광고 메시지를 전송한 경우, 그 메시지가 성공적으로 전송되었는지 여부를 알 수 있는 충돌 감지 기법 (CD: Collision detection)을 도입함으로써 확률적 이웃 탐색 기법의 성능을 더 높일 수 있다. 시뮬레이션 결과는 제안 기법이 모든 이웃을 탐색하기까지 소요되는 시간을 15.6%~57%까지 감소시킬 수 있음을 보여준다.
