Purpose: This study was designed to search for nursing intervention strategies centering around the meaning structure of the nurse's turnover experience by applying phenomenological methods. Methods: The participants were 6 nurses in small and medium sized hospitals who had experienced at least 1 turnover. Data were collected used MP3 records. The data analysis was done by Giorgi (1985) method. Results: The results were divided into the following categories: 1) Careless decision: wrong decisions, imprudent desire, insufficient patience, unclear future, 2) Inappropriate working environment: irregular working hours, high workload, poor working environment, insufficient understanding of related divisions, lack of opinion collection, low salary, 3) Interpersonal relations problems: discord with colleagues, difficulty in relationships with others, difficulty in daily lives, 4) Lack of specialization: feeling of inertia, lack of role identification, lack of self identification, 5) Inappropriate coping: regret with clinical challenges, difficulty with a new environment, repentance, expectation, relative humility, 6) New self-dignity: expectation, new challenge, relaxing lives, decisions based on future-oriented confidence. Conclusion: The finding of this study will offer profound information on the nurse's turnover experience and provide basic raw materials for improving the quality of nursing performance and contribute to the development of hospital organization.

This study was to determine the inappropriate drug use in pediatric outpatients who received 2 or more prescriptions on the same day. Retrospective drug utilization reviews (DURs) were implemented to samples obtained from national health insurance claims data during December 2008 to February 2009, using 5 DUR criteria (duplication, drug-drug interaction, drug-disease interaction, drug-age contraindication, incorrect dosage) established in the Drug Information Framework (DIF)-$Korea^{TM}$, DUR program. Among 38,451 claims analyzed in the study, 74.7% had more than one conflicts in the 5 DUR modules. Among 16,472 patients analyzed, 49.6% had conflicts with duplication criteria composing of ingredient duplication (23.3%) and therapeutic class duplication (39.6%). Incorrect dosages were found in 73.6% of patients and under-dosage conflicts accounted for 59.9%, which was higher than over-dosage conflicts (38.3%). In this study, inappropriate drug prescriptions such as under-dose, pediatric contraindication and therapeutic duplication were prevalent in pediatric outpatient settings, suggesting much more awareness to the society, to prevent drug related problems in a vulnerable pediatric group.

무선 센서 네트워크는 환경 모니터링, 감시 시스템, 무인 우주 탐사 등의 다양한 분야에서 활용 가능하다. 하지만 노드의 부적절한 배치로 인해 센싱할 수 없는 지역이 생기거나 특정 지역에 노드가 과도하게 중복 될 수도 있다. 이는 데이터 수집을 어렵게 하고, 에너지 낭비를 야기할 수 있다. 본 논문에서는 노드 재배치를 통해 이러한 배치 문제를 해결한다. 먼저 중복 배치된 노드를 찾고, 이 노드들을 센싱할 수 없는 지역으로 옮겨서 최대한 넓은 지역을 센싱할 수 있도록 한다. 본 논문에서는 이를 위해 필요한 효율적인 알고리즘을 제안하고 시뮬레이션을 통해 제안 방법을 검증하였다.

Offshore software development (OSD) is international business collaboration. OSD projects often encounter intercultural and inter-linguistic problems disturbing the projects. Business documents are formal media of information and knowledge for OSD. While OSD documents should convey common understanding of the OSD products, the documents may contain unsuitable expressions which draw misunderstanding of the required products and offensive issues for the collaboration. Intercultural and inter-linguistic differences cause mistakes and inappropriate expressions. OSD from Japan to China is the largest in Asia, and Japanese language is often used in OSD documents. Large similarity is found between Japanese and Chinese in their languages, while many differences exist even for the same word. The similarity induces to write unsuitable expressions for both sides of OSD. To introduce risks for OSD projects caused by unsuitable or inappropriate expressions in OSD documents, we propose to apply a proofreading system of Japanese documents for OSD. Japanese consignor uses the system to refine OSD documents written by Japanese engineers for Chinese readers, and Chinese consignee uses it to refine Japanese documents written by Chinese Engineers as derivatives of OSD projects. Effectiveness of applying the proofreading system is discussed for actual projects.

Shewhart X-chart, which is most widely used in practice, is shown to be inappropriate for the cases where the process distribution is one-sided asymmetrical, and thus some nonparametric Shewhart type charts are developed instead. These schemes may be applied usefully when there is not enough information in determining the process distribution. The average run lengths are obtained to compare the efficiency of control charts for various shifts of the location parameter and for some typical one-sided asymmetrical distributions.

Approximation of a Cartesian straight line motion with linear interpolation in the joint space has many desirable advantages and applications. But inappropriate determination of the corresponding subtravelling and transition times makes such joint-trajectories violate the input torque/force constraints. An approach that can overcome this difficult and yield the joint trajectories utilizing the allowable maximum input torque/force is established in this paper. The effectiveness of these results is demonstrated by using a three-joint revolute manipulator.

정보사회의 중심이 되는 정보네트워크로서 인터넷은 사회의 커뮤니케이션 도구의 역할을 하고 있으며 인터넷을 통한 언어사용은 더 이상 피할 수 없는 현실인 것이다. 이에 본 연구에서는 인터넷상의 언어사용에 대한 이론적 근거를 마련하고, 현재 나타나고 있는 인터넷상의 부적절한 언어사용 실태를 '음운ㆍ표기', '문법', '어휘ㆍ의미'로 나누어 조사$\cdot$분석하였으며, 그 결과를 바탕으로 '디지털적 사고', '이용자 추이', '네티켓과 정보교육' 등이 토론되었다.

General technique and management technology of agriculture have development in every year to ensure the competitiveness of agriculture. Accordingly, Interested in using information systems management technology is improving. For information system, the first system of rural buildings category should be established. Classification system is set up through each specific code. and it takes advantage of the information system is to achieve the computerization of agricultural society. Therefore, in this study construction information classification system, quantity of output category, got to the standard classification system architecture, apply to agricultural buildings to review the situation and saw a problem. The result, it is the complexity and broad scope, and it is set to inappropriate setting of the Category item.

Group key agreement protocols derive a shared secret key for a group of users to ensure data confidentiality or/and integrity among the users in the subsequent communications. In this paper, we inspect two group key agreement schemes which have been proposed by Shi et al. and Zheng et al. in 2005 and 2007 respectively. Although both schemes were claimed to be secure in a heuristic way, we reveal several flaws using the Bellare-Rogaway security model extended to multi-party setting by Bresson et al. These flaws are found to be originated from inappropriate selection of key derivation function, inadvertent exclusion of partners' identities from the protocol specification and insufficient consideration in preserving known temporary information security and key freshness properties. Furthermore, we suggest and discuss proper countermeasures to address such flaws.

The channel level difference (CLD) is a main parameter in the reference model 0 (RM0) for MPEG Surround. Nevertheless, the CLD quantization method in the RM0 has problems such as the lack of theoretical background and inappropriate quantization levels. In this letter, a new CLD quantization method is proposed based on the virtual source location information which has strength in the quantization process. From experimental results, it is confirmed that the proposed scheme greatly reduces the quantization distortions measured in dB and degrees without any additional complexity.
