최근 정부의 창조과학의 일환으로 과학교육의 활성화를 위한 정책을 추진하고 있지만 과학전시는 인프라의 부족과 예산 및 인력의 부족으로 많은 어려움을 겪고 있는 현실이다. 과거의 과학관은 현장학습 체험의 대표적인 장소이자 유청소년들의 호기심의 장소였다. 그러나 현대에는 과학관의 경쟁상대는 테마파크나 온라인 게임들이 경쟁의 대상으로 부각되어지면서 체험과 교육이라는 두 가지 목표를 달성하기 위한 과학체험 전시기기의 변화가 요구되어진다. 해외 선진 과학관의 사례를 살펴보면 과학관이 단순한 과학교육 체험의 장이 아닌 하나의 문화공간으로서 휴식과 엔터테인먼트를 제공하고 있으며, 과학이외에도 주변 생활을 다양한 장르의 예술이나 패션 등과 결합하여 전시를 기획하고 있다. 본 연구에서는 현재의 획일화 되어진 전시기기의 설명 패널을 디지로그 북을 이용한 설명 패널로 교체하여 관람객의 연령과 학년에 맞춘 서비스를 제공함으로서 과학지식에 대한 지적 호기심 유발과 관람객의 만족도를 높일 수 있는 방안을 제시 하고자 한다.

A 10-year old female Yorkshire terrier with nasal discharge and swelling was referred to the local animal hospital. Abnormal mass of right nasal cavity was detected in physical examination and radiography. According to the radiographs of the head, there was an evidence of bony destruction in right nose. Oronasal fistula was detected in right maxillary canine teeth. After surgical excision, the sample of nasal mass was refereed to Pathology Department of Veterinary Medicine in Jeju National University. Grossly, the enlarged mass was soft and 3 ${\times}$ 3 cm in size. Histopathologically, the neoplastic mass was composed of tubular to tubulopapillary structures which were lined by single to 6~7 layers of cuboidal to ciliated columnar cells. These neoplastic cells showed invasive tendency to adjacent normal parenchyma. They had uniform, round to oval nuclei, cytoplasm with small vacuoles and indistinct cellular margin. The number of mitotic figures was varied in different areas, ranged from 0 to 4 per high power field. Necrotic foci and infiltration of inflammatory cells including neutrophils, lymphocytes, and plasma cells also presented in the mass. Immunohistochemically, the neoplastic cells demonstrated strong positive reaction for cytokeratin (CK) 18 but were negative for CK 7 and 8. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as nasal adenocarcinoma originated from respiratory epithelium.

Purpose: To identify an associations between health care workers' uniforms and health care-associated infection. Methods: Electronic databases, including Ovid-Medline, the Cochrane Library, CINAHL, EMBASE, KMbase, and KoreaMed, were searched. The search terms included doctor, nurse, health care worker/staff/assistant, clothing, (white) gown, uniform, (neck)tie, and attire. Only papers published in English and Korean were included. Results: 16 studies were selected from 1,900 references screened. All of the studies were non-comparative studies except for one. Four were conducted with doctors, six with nurses, one with health care workers including physiotherapists and one for medical staff plus visitors in a neonatal intensive care unit. Doctors more frequently changed their uniforms than neckties; therefore, the degree of contamination was more serious in neckties. The cuff zone was more likely to be heavily contaminated than other areas of long-sleeve gowns. Coats become contaminated quickly once worn, and colony counts reached a similar level within the first few hours after wearing them. Wearing a plastic apron or protective clothing did not prevent the bacterial contamination of nurses' uniforms, and the best way to decrease the contamination was changing to newly laundered uniforms before starting every duty. Conclusion: Healthcare workers' uniforms are a potential source of health care-associated infection although there was no robust evidence. The government must establish standards for laundering of uniforms or a requirement for institutions to provide a laundering service for healthcare workers' uniforms.

On June 27, 2002 Canadian Internet Registration Authority (CIRA) launched dot-ca domain name dispute resolution service through BCICAC and Resolution Canada, Inc. The Domain name Dispute Resolution Policy (CDRP) of CIRA is basically modelled after Uniform Domain Name Dispute Resolution Policy(UDRP), while the substance of CDRP is slightly modified to meet the need of Canadian domain name regime and its legal system. Firstly, this article examined CIRA's domain name dispute resolution policy in general. It is obvious that the domain name dispute resolution proceeding is non-binding arbitration to which arbitration law does not apply. However it still belongs to the arbitration and far from the usual mediation process. Domain name arbitrators render decision rather than assist disputing parties themselves reach to agreement. In this respect the domain name arbitration is similar to arbitration or litigation rather than mediation. Secondly it explored how the panels applied the substantive standards in domain name arbitration. There is some criticism that panelists interprets the test of "confusingly similar" in conflicting manner. As a result critics assert that courts' judicial review is necessary to reduce the conflicting interpretation on the test of substantive standards stipulated in paragraph 3 of CDRP. Finally, it analysed the court's position on domain name arbitral award. Canadian courts do not seem to establish a explicit standard for judicial review over it yet. However, in Black v. Molson case Ontario Superior Court applied the UDRP rules in examining the WIPO panel's decision, while US courts often apply domestic patent law and ACPA(Anticyber -squatting Consumer's Protection Act) to review domain name arbitration decision rather than UDRP rules. In conclusion this article suggests that courts should restrict their judicial review on domain name administrative panel's decision at best. This will lead to facilitating the use of ADR in domain name dispute resolution and reducing the burden of courts' dockets.

Nursing role tends to be more complex then before because of the increased number of health professionals and of the health needs of patient. Accordingly, nursing role expectations are various and sometimes conflict by its role set. There are various literatures on role conflict of nurses and discussed how to eliminate the conflict in order to improve nursing service particularly in the hospital organization. This study was designed to determine if role conflict exist among nurses who work in a hospital and if so what resolution were most frequently selected by the nurses to the role conflict. The study population was fifty six registered nurses of K university hospital. The fifty six was defined and selected by nonproportional stratified sampling method to obtain subjects who are from uniform role set. A questionnaire, a list of role connect, stimulated by the literature review, knowledge based on several years' experience in nursing was formulated by the author and administered to the study population. The questionnaire included twenty nine closed question items of role conflict and classified according to the intra sender conflict, intersender conflict, person conflict and interperson conflict. The response choices to the questions range on a scale continuum with degrees of conflict from one to five: never - 0, seldom - 1, occasionally - 2, frequently - 3, and mostly -4. Per cent, means, standard deviation, and x² -test were used to analyze data. The findings of the study could be summarized as follows. 1. General characterstics of the study population: Most of the population were between the age of 22-27 and are not married. 2. Analysis of Role conflict Existence of Role conflict of nurses was found by the total mean conflict score, 2.06. Inter Sender Role conflict revealed the most high mean conflict score and the lowest one was inter person role conflict. Among the five role senders of nurses: Physician, patient and hi9 family, peer and superior, nursing students and hospital administrator, nurses showed the highest conflict mean score for physicians and the lowest score for Nursing student. 3. Analysis of role conflict resolution. Compromise through discussion with the role sender was the most frequently selected method by the respondents. The result also showed that the respondents tend to resolve the conflicting situation created by patient or his family by persuation. On the o thor hand, Avoidance and ignorance was frequently chosen for the conflicting role expectations from the hospital administrator.

Objectives: The purpose of this study is to provide the basic data for efficient operation and management of the military foodservice by analyzing the satisfaction of the quality of the foodservice and the perception of the military foodservice which are provided according to the ranks of the soldiers. Methods: A total of 252 military personnel (48 Private, 87 Private first class, 74 Corporal and 43 Sergeant) participated in Gyeonggi area from November 1 to 30, 2013, and data were analyzed by the SPSS Win (ver 18.0). Results: The perception with foodservice, variety of menu (p < 0.001), importance (p < 0.01), problem (p < 0.05) and leftover reason (p < 0.05) significantly differed by the rank of the soldiers. With regard to the satisfaction with food, there were significant difference by rank for all items (p < 0.01). Satisfaction with facilities did not indicate significant differences by rank. Satisfaction with sanitation indicated significant difference by rank in the categories of table ware (p < 0.05), process of distribution (p < 0.05), employee's uniform (p < 0.001) and drinking water (p < 0.05). Satisfaction with service indicated significant difference by rank with regard to kindness of employees (p < 0.01), providing information on foodservice (p < 0.05) and fast distribution (p < 0.01). Conclusions: In order to improve the satisfaction of all ranks, there is a need to offer a variety of nutritionally balanced menu and a proper amount of food provided through the voluntary food distribution services. The results also suggested the need to find a sustainable foodservice management plan to carry out satisfaction surveys regularly in the military foodservice.

A finite element computer code for short-term analysis of steel-concrete composite structures is extended to study long-term effects under service loads, in the present work. Long-term effects are important in engineering design because they influence stress and strain distribution of the structural system and therefore contribute to the increment of deflections in these structures. For creep analysis, a rheological model based on a Kelvin chain, with elements placed in series, was employed. The parameters of the Kelvin chain were obtained using Dirichlet series. Creep and shrinkage models, proposed by the CEB FIP 90, were used. The shear-lag phenomenon that takes place at the concrete slab is usually neglected or not properly taken into account in the formulation of beam-column finite elements. Therefore, in this work, a three-dimensional numerical model based on the assemblage of shell finite elements for representing the steel beam and the concrete slab is used. Stud shear connectors are represented for special beam-column elements to simulate the partial interaction at the slab-beam interface. The two-dimensional representation of the concrete slab permits to capture the non-uniform shear stress distribution in the horizontal plane of the slab due to shear-lag phenomenon. The model is validated with experimental results of two full-scale continuous composite beams previously studied by other authors. Results are given in terms of displacements, bending moments and cracking patterns in order to shown the influence of long-term effects in the structural response and also the potentiality of the present numerical code.

This study was undertaken to determine the normal appearance of the postpartum uterine involution. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in 8 Miniature Schnauzer dogs. Vaginal discharge was observed visually during the 3 weeks of postpartum. A large amount of viscous dark green discharge changed progressively to a small amount of transparent discharge. In the uterine shape, the transverse images were crescent or polygonal at the beginning, but became circular after 16 days. At postpartum day 24, the longitudinal images of placental and interplacental sites were similar to each other The echogenicity of uterine structure was clearly distinguishable among the hyperechoic serous membrane, hypochoic myometrium, hyperechoic endometrium, and anechoic uterine contents during the first week postpartum, but afterward the interluminal boundaries and echogenicity became obscure gradually. In addition, the anechoic substance of the endometrial cavity was not observed after postpartum day 28. In the uterine diameter, the diameter of placental sites decreased markedly from 24 mm at the first day postpartum to 13 mm at day 7, and the diameter of interplacental sites decreased from 15 mm at postpartum day 1 to 10 mm at day 7. At postpartum day 65, the uterus (6.4 mm) changed little and had a uniform homogenous echo, and thus it was confirmed that uterine involution was completed at that time in Miniature Schnauzer dogs.

The double-lane arrangement model is frequently used in underground coal mines because it is beneficial to improve the mining efficiency of the working face. When the double-lane arrangement is used, the service time of the reserved roadway increases by twice, which causes several difficulties for the maintenance of the roadway. Given the severe non-uniform deformation of the reserved roadway in the Buertai Coal Mine, the stress distribution law in the mining area, the failure characteristics of roadway and the control effect of support resistance (SR) were systematically studied through on-site monitoring, FLAC 3D numerical simulation, mechanical model analysis. The research shows that the deformation and failure of the reserved roadway mainly manifested as asymmetrical roof sag and floor heave in the region behind the working face, and the roof dripping phenomenon occurred in the severe roof sag area. After the coal is mined out, the stress adjustment around goaf will happen to some extent. For example, the magnitude, direction, and confining pressure ratio of the principal stress at different positions will change. Under the influence of high-stress rotation, the plastic zone of the weak surrounding rock is expanded asymmetrically, which finally leads to the asymmetric failure of roadway. The existing roadway support has a limited effect on the control of the stress field and plastic zone, i.e., the anchor cable reinforcement cannot fully control the roadway deformation under given conditions. Based on obtained results, using roadway grouting and advanced hydraulic support during the secondary mining of the panel 22205 is proposed to ensure roadway safety. This study provides a reference for the stability control of roadway with similar geological conditions.
