최근 녹색도시를 지향하면서 도시 내에서의 물의 순환에 대한 관심이 높아지고 있으며 도시계획 단계에서부터 물의 순환을 고려하려는 시도가 이루어지고 있다. 국토해양부, 환경부, 소방방재청 및 지방자치단체들은 법령, 기준, 지침 및 조례 등을 제정하여 물순환을 도시개발 이전의 상태가 될 수 있도록 시설 설치를 유도하고 있다. 그러나, 개별시설들의 조합이 유역규모의 물순환에 미치는 영향 평가는 이루어지고 있지 못한 실정이다. 종래에는 홍수저감을 목적으로 홍수저류지와 침투시설에 대하여 설계하고 시공을 하였으나 장기적인 관점에서 LID 시설의 효과를 평가하여 도시 계획 단계에서 반영하지는 못하였다. 그리고 이들 개별 LID 시설(침투, 저류 등)에 대한 단위 시설의 규모 설계에 그치고 있어 개선 시설이 다중으로 조합되어 분산 계획되었을 경우, 유역 규모에서 물순환의 긍정적인 변화를 판단하기는 어려운 형편이다. 도시지역에서의 LID(Low Impact Development) 효과 분석과 연계된 유역 물순환 해석을 위하여 독일, 호주 및 미국에서는 STORM, Urban Developer, SUSTAIN(System for Urban Stromwater Treatment, and Analysis INtegratration) 및 SWMM LID(Storm Wastewater Management Model LID) 등의 모형을 출시하고 실무에 적용하고 있다. 그러나, 해외에서 개발된 기술은 국내의 유역 환경을 충분히 반영하기 어렵다. 저수지 혹은 하천에서의 취수 등과 같이 국내의 복잡한 물순환 형태를 반영하는데 한계가 있으며, 기존의 물순환 해석모형에 의한 LID 시설을 계획하는 방법은 홍수저감에 국한되어 있고, 하천 유량이나 지하수위 측정 자료가 부족한 대상지역에 대한 장기적인 유역 물순환 및 도시 개발과 같은 토지이용 변화가 물순환에 미치는 영향을 해석하는데 있어 제한이 있고, 개별적으로 설치된 LID 시설들이 유역의 물순환을 개선하는 효과를 종합적, 정량적으로 구현하는데 한계가 있다. 본 연구에서는 도시 개발 지역의 장기간에 걸친 물순환의 변화를 예측하고 물순환을 개선시키는 대안 시설의 효과를 사전에 평가하는 것을 목표로 김현준 등(한국건설기술연구원, 2011)이 개발한 유역 물순환 해석 모형인 CAT(Catchment hydrologic cycle Assessment Tool)을 이용하였다. 특히, CAT은 사용자의 목적에 맞는 다양한 물순환 개선시설(침투시설, 저류지, 습지, 빗물저장 시설, 리사이클 및 외부급수 등)의 구현 및 모의가 가능하도록 개발되었다. 대상유역으로는 경기도 Y지구를 선정하였으며 도시개발 시나리오(전원도시 및 산업도시 등)에 따른 LID 효과 분석을 실시하였다. 대상지역에 대한 도시유형별 개발계획에 따른 개발 전 후 물순환 변화량 분석 및 LID 시설 계획에 의한 물순환 개선효과를 살펴보면 1998년부터 2007년까지의 평균 강우량을 1,271mm라고 할 때 산업도시의 경우 도시 개발 전의 증발산, 직접유출 및 기저유출은 각각 53%, 29%, 19%로 나타났으며 도시 개발 후 35%, 54%, 12%로 직접유출이 개발 전에 비해 86%나 증가하여 개발에 따른 영향이 큰 것으로 나타났다. 따라서, 이러한 개발에 따른 영향을 최소화하기 위하여 LID 시설을 계획하여 효과를 분석한 결과 증발산, 직접유출, 기저유출이 44%, 34%, 13%로 나타나 도시 개발 후의 왜곡된 물순환 체계가 개발전의 수준과 근접하게 나타나 LID 시설의 긍정적인 효과를 검토할 수 있었다. 이상에서와 같이 CAT 모형을 사용하여 도시유역의 물순환 체계를 진단하고, LID 시설의 효과를 평가할 수 있게 됨으로써 향후 도시유역에 대한 물순환 정상화를 실현하기 위한 정책 수립에 기초자료를 제공하고, 설계 실무에 활용될 수 있을 것이다.

In order to respond and prevent underground safety accidents, the Korean government has been preparing a submitting completion drawing web system project for converting the current manual-based 3D Underground Geospatial Map construction and its update system to an automation-based 3D underground information construction. However, research on standard drawings required for the automatic update of 3D underground structures is insufficient, so detailed research is needed. In this research paper, a standard map-based 3D underground structure construction plan was presented for the six types of underground structures constituting the 3D Underground Geospatial Map, enabling rapid and accurate drawing data creation and systematically 3D underground structure drawing data could be managed. In addition, we developed a 3D construction drawing tool that can be used in underground information practice so that ordinary CAD program users can easily produce processing drawings. The results derived from this paper are expected to be major reference materials for the establishment of standard frameworks and practical application guidelines for the construction of 3D underground structures in the future.

The purpose of this study was to investigate the feasibility of field operation protocol for cardiopulmonary resuscitation(CPR) in person with non-traumatic arrest. This study was performed from May 1 through June 27, 2008, and subjects were 150 students who are attending the department of Emergency Medical Service in J and K universities which located in Jeollabuk-do and Jeollanam-do areas. Practical conformance was verified using by nonequivalent control group pretest-posttest design. This study divided into two groups; experimental group that employed field operation protocol and control group that applied conventional CPR protocol, and comparative analyzed statistically the necessary time of the items of each protocol. The results indicated that each performance time of 18 items was reduced over 3 seconds except 5 items(assessment of consciousness, airway control, two times of artificial respiration, check of circulation, and five cycles of CPR). And time of 6 items(intubation, peripheral intravenous line, reassessment of consciousness, pupil reaction, carotid artery pulse, and vital sign) was minimized more than 60 seconds, and total performing time was shortened 110.85 seconds. The results suggested that total performing time in pre and post test where the protocol was applied for two groups showed a statistically significant decrease(t=-6.580, p=.000). Consequently, field operation protocol for cardiopulmonary resuscitation(CPR) in person with non-traumatic arrest will be a available manual which support prompt and accurate decision making, and improve emergency medical service.

In this study, we attempted to provide a distinctive cognitive, emotional 'Auditory User Interface (AUI) Design Guideline' according to home appliance groups and their functions. It is an effort to apply a new design method to practical affairs to overcome the limit of GUI centered appliance design and reflect user multimodal properties by presenting a guideline possible to generate auditory signals intuitively associable with the operational functions. The reason why this study is required is because of frequent instances given rise to annoyance as not systematic application of AUI, but arbitrary mapping. This study tried to provide a useful guideline of AUI in home appliances by extracting the relations with cognitive, emotional properties of a certain device or function induced by several properties of auditory signal and showing the empirical data on the basic mechanism of such relations.

Transactions activation of intangible assets has become became a key factor for corporate survival and successful business in the knowledge economy. Thus, demand in correctly valuating technology has increased. The market approach is the reliable method because of the premise that the market value of an asset is directly related to the prices of comparable, competitive ones. However, it can be practically impossible in many cases because it is hard to find identical transactions, which are generally closely guarded business secrets. As a result, most of technology valuation is conducted by the income approach and this approach is used to derive estimates for such unobserved variables. In September 2011, the Ministry of Knowledge Economy enacted a law for operational guideline standards for technology valuation to encourage the domestic technology valuation market. The enforcement recommended that the market approach have precedence over other approaches. If this approach cannot be applied, then the valuator should writing that he used other approaches. In practice, it is hard to know whether or not information about comparable transactions exists. The proposed process provides valuators to assess suitability for practical use of market approach through the observation process of technology transactions information. At the same time, it offers them the opportunity to gain validity when using other approaches.

Although three types of the information security measures (technical, physical and managerial ones) are all together critical to maintaining information security in the organizations and should be implemented at the same time, this study aims at providing theoretical basis of establishing and implementing effective managerial security measures. The rationale behind this research objective is that it is very important to effectively perform the managerial security measures to achieve the target performance level of the technical and the physical security measures because main agents of practicing the information security measures in the organizations are staff members even though the technical and the physical ones are well constructed and implemented. In particular, this study intends to develop and propose the theoretical model applicable to providing the way of improving organizational members' intention to use information security technologies since the very intention to use them is essential to effectively establishing and promoting managerial security measures. In order to achieve the objective of this study, the factors critical to influencing upon the intention to use information security technologies are derived through systematically reviewing related theories and previous studies, and then the research model and hypotheses are proposed by logically reasoning the casual relationship among the these factors. Also, the empirical analyses are performed by conducting the survey of the organization members of domestic large companies and analyzing the structural equation model by PLS (Partial Least Squares) method. The significant results of this study can contribute to expanding the research area of managerial information security and can be applied to suggesting the practical guidelines for effectively establishing and implementing the managerial security measures in various organizations.

Based on theoretical background of Situational Theory of Problem Solving(STOPS), we have examined the role of STOPS variables on a group of online public in their issue recognition and communicative behavior on Korea's nationwide civil boycott movement of Japanese goods. Results from 524 survey cases from a Korea's major online community show that two independent variables(Problem Recognition, Referent Criterion) revealed positive in their effect on mediating variable(Situational Motivation in Problem Solving). Situational Motivation also revealed positive in its effect on six dependent variables(Information Forefending, Information Permitting, Information Forwarding, Information Sharing, Information Seeking, Information Attending) of Communicative Behavior. Involvement Recognition and Constraint Recognition revealed positive without proper statistical significance. As a result, study on the case of online public in Korea supports STOPS theory as high-level of Problem Recognition and Referent Criterion effects on Communicative Behavior in positive way via Situational Motivation. Implications from the findings have discussed and proposed suggestions for government public relations and further studies.

본 연구는 유량에 의한 수면폭의 변화로 인한 하천경관의 시각적 선호도에 미치는 선호요인 파악하였다. 등간척도의 점수부가체계를 적용하여 이용자에 의한 금강경관의 시각적 선호를 평가한 후 시각적 선호와 이에 영향을 미치는 선호요인들과의 관계를 다중회귀분석방법으로 검정하였다. 수면폭 변화에 따른 금강경관의 시각적 선호요인 변수는 심미성 인자, 물리적 특성 인자, 복잡성 인자로서 3개 변수 모두 유의성이 있는 것으로 판명되었다. 모든 선호요인의 값이 증가함에 따라 시각적 선호의 값도 증가를 가져오고 그 반대의 경우도 마찬가지였다.다중회귀모형에서 다른 조건이 불변일 경우, 심미성 인자의 값이 증가할 때 전체적인 시각적 선호에 가장 크게 영향을 미치고, 다음으로 물리적 특성 인자가 두 번째로 영향을 미치는 것으로 판명되었다. 선호요인이 시각적 선호에 기여하는 상대적 중요도는 심미성 인자, 물리적 특성 인자, 복잡성 인자 순으로 나타났다. 심미성 인자는 복잡성 인자에 비해 3.2배 만큼 중요도가 크며 물리적 특성 인자는 복잡성 인자에 비해 3배의 중요도를 가지고 있는 것으로 나타났다. 따라서 심미성인자는 가장 중요한 선호요인으로 판명되었다. 수면폭 변화에 따른 금강경관의 시각적 평가에 의한 선호 요인 분석 결과는 하천의 수면폭 및 수량에 큰 영향을 미칠 것이다. 수위 변화로 인한 하천 경관의 선호 요인을 파악함으로서 금강 유지유량의 결정에 지침을 마련하고, 시각적 선호도에 따른 최적의 수면폭/하폭비 산정하였으며 본 연구 결과는 수량에 의한 수면폭/하폭 비의 변화로 인한 하천경관의 수량결정에 중요한 정보를 제공하고 이용자의 만족을 극대화할 수 있는 경관조성에 기여할 것으로 판단된다. 통하여 유기농업의 실현을 도모하여 소비자의 욕구에 맞는 작물 생산 및 농촌관광단지 조성을 통해 부가가치증대 및 소득증대를 꾀함으로 농촌문제 해결에 도움이 될 것으로 기대된다. 본 연구를 통해 GIS 와 RS의 기술이 농촌분야에 더 효율적으로 적용될 것으로 기대되며, 농업기술센터를 통한 정보제공을 함으로써 대농민 서비스 및 농업기관의 위상이 제고 될 것으로 기대된다.여 전자파의 공간적인 가시화를 수행할 수 있었다. 본 전자파 시뮬레이션 기법이 실무에 이용될 경우, 일반인이 전자파의 분포에 대한 전문지식을 습득할 필요 없이, 검색하고자 하는 지역과 송전선, 전철 등 각종 전자파의 발생 공간 객체를 선택하여 실생활과 관련된 전자파 정보에 예측할 수 있어, 대민 환경정보 서비스 질의 개선측면에서 획기적인 계기를 마련할 것으로 사료된다.acid$(C_{18:3})$가 대부분을 차지하였다. 야생 돌복숭아 과육 중의 지방산 조성은 포화지방산이 16.74%, 단불포화지방산 17.51% 및 다불포화지방산이 65.73%의 함유 비율을 보였는데, 이 중 다불포화지방산인 n-6계 linoleic acid$(C_{18:2})$와 n-3계 linolenic acid$(C_{18:3})$가 지질 구성 총 지방산의 대부분을 차지하는 함유 비율을 나타내었다.했다. 하강하는 약 4일간의 기상변화가 자발성 기흉 발생에 영향을 미친다고 추론할 수 있었다. 향후 본 연구에서 추론된 기상변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전

Purpose: This study was to identify the role of general hospice palliative nurse through job analysis (duties, task, and task elements). Methods: The sample consisted of 136 nurses or professors who were performing duties related to hospice care areas in Korea. A survey method was used, and the questionnaire included frequencies, criticality, and difficulties of task elements in job description by the DACUM method. Descriptive statistics were performed by using SPSS WIN 17.0. Results: The job description of general hospice palliative nurse was identified 8 duties, 36 tasks, and 137 task elements. As for the 8 duties, the average scores of frequency, criticality, and difficulty were 2.94, 3.66, and 2.80, respectively. The role of ‘pain assessment’ was the most important task element among frequency and criticality. The lowest score at the frequency and criticality were ‘manage public finance’ and ‘collect datum through diagnostic test & lab', respectively. Furthermore, the role of 'identify spiritual needs of patients and family' was the most difficult task, whereas the role of 'manage documents and information' was the least. Conclusion: In this study, we could recognize the reality of general hospice palliative nurse's performances. For general hospice palliative nurse, therefore, concrete practice guide lines of psychosocial and spiritual care, communication skills, and bereavement care with qualifying system are critically needed.
