This study is a descriptive research study to analyze knowledge and attitude about CAM and aromatherapy for health department students in H8 university health department students(528 students) in Chungcheongdo-do. The results of this study showed that the treatment methods and therapeutic advantages of CAM showed a positive attitude and the recognition of the therapeutic effect on aromatherapy was somewhat higher. However, the knowledge level of aromatherapy was rather low. The students of the department of health science showed a relatively high awareness of the need for education in CAM, but aromatherapy showed a relatively low perception. Therefore, in order to reduce patient welfare and symptom in health department, it is necessary to develop knowledge training for knowledge application and effective treatment and development of clinical practice program for various treatment methods.

Rapid technological innovation led by digitization has significantly changed the business of digital content goods, and has led to the emergence of new forms of services, such as music streaming. However, whether the streaming service is a threat to the traditional downloading service is still under debate. In this study, we examine whether music downloading is a substitute for or a complement to music streaming by investigating the moderating effects of LTE technology penetration. Using a unique dataset on the online music market from a dominant music platform in Korea, we found that music downloading services are complementary to music streaming services, but this complementary relationship is significantly and positively moderated by the introduction of LTE technology.

태양열 이용은 대체에너지자원 가운데 가장 널리 분포되어 있고 기술력에 따라 얼마든지 사용할 수 있는 태양열에너지를 그 대상으로 하고 있기 때문에 자연친화적이며, 친환경적인 접근방식으로 기술 개발 및 이용보급 정책을 함께 추진해야 할 것이다. 건물에너지 절약 기술도 국가에너지수요의 $30{\%}$이상을 차지하는 광범위하고 다양한 건물에너지 수요를 효율화하고 절감하는데 그 목적이 있으므로 기존의 건물에너지 이용방식의 문제, 효율개선방안, 그리고 신기술개발 및 환경친화적 건축설계등 기술 개발과 건축관련 정책을 병행 추진해야 그 효과를 기대할 수 있다. 따라서 기술개발 계획 수립, 연구개발 수행, 기술 이전 및 상용화 그리고 실용화 보급정책 시행의 전과정에 걸쳐 상호 보완적이고 체계적인 운용으로 효율을 극대화하고 파급효과를 높일 수 있을 것이다. 본 논문에서는 국가 에너지기술개발 10개년 계획의 목표와 틀 안에서 대체 에너지 기술 개발사업과 에너지 효율향상 기술개발 사업에 포함되어 있는 태양열 이용과 건물 에너지 절약기술에 관련된 프로그램들을 중심으로 효율적 운영방안 등을 검토하고자 한다. 또한 각각의 프로그램들이 가지는 특성과 연관성을 검토하여 추가 보완사항이나 정책대안을 제시하고자 한다.

In this paper, we implement an AAC(Augmentative and Alternative Communication) system based on image dictionary in order that speech defectives can easily communicate their opinion to others by using images. Normally, those who have a speech defect use only a few limited words to express their intentions and it is an effective way to use images in their communication because they have a difficulty in speaking. Therefore we make verbal images of verb and adjective that play an important role in expressing the speaker's intention, define pattern of semantic relation between the verbal images and noun images, and construct the image dictionary. In this AAC system, when a user clicks a verbal image, the system generates a sentence by selecting noun images which are component parts of corresponding pattern based on semantic relation with the verbal image. We evaluate the implemented system by how efficiently children of speech defect can express their intention and the result shows more than 70% of success rate in communication.

Purpose: The purpose of this study was to analyze the reason to select complementary and alternative therapy for terminally ill cancer patients. Methods: The data were collected from 21 terminal cancer patients and families through the in-depth interview. Data analysis were performed by the Colaizzi's phenomenological method (1976). Results: The reason to select complementary and alternative therapy for terminal cancer patients and families was then categorized with 4 elements; Awareness of limitations in contemporary medical treatments, Belief in effectiveness of the CAM, Satisfaction with emotional needs of family members, and Disbelief due to negative attitudes of physicians. The result indicated the following 9 themes expectation for a complete cure, uncertainty in hospital treatments, complementary method for management of side effect of chemotherapy, alleviation of symptoms and life-sustaining, fear for side effects of cancer treatments, belief in earned information, referrals by other, responsibility of family, and dissatisfaction with negatine attitudes of physicians. Conclusion: Physicians should provide a sufficient explanation and try to effectively communicate with clients about hospice and palliative service and the CAM. We strongly realized that concerns about patients' best care and satisfactions with family's needs should be understood.

Purpose: This study was to analyze the effect size of complementary and alternative intervention studies in reference to dysmenorrhea and menstrual distress. Methods: In order to conduct a meta-analysis, a total of 393 studies were retrieved from the database. Twenty-eight studies that were published from March 2001 to February 2011 were selected. Results: Intervention studies included seven studies on aromatherapy, five on auriculotherapy, three on each Koryo-Sooji-Chim and moxibustion, two on each heat therapy and magnetic therapy and six on other therapy. The effect size of the intervention studies on dysmenorrhea and menstrual distress was greater than 0.48 for Koryo-Sooji-Chim, moxibustion, aromatherapy, auriculotherapy and other therapy. Conclusion: This study suggests that drug free therapy can reduce the levels of menstrual distress, despite the small number of intervention studies and randomized controlled trials.

In order to incorporate substitution effects between different transport modes in optimal road Pricing, relating economic theories and models have been reviewed. It includes unconstrained optimization problem of maximizing separable and non-separable social net benefit functions of different substitutable urban transport modes. In doing that, the problem and limitations such as path-independent conditions with the asymmetric Jacobian of the objective function have been reviewed. Consequently, a plausible way of deriving optimal road price under interdependent market conditions has been suggested so that the idea can help identifying desirable and acceptable urban transport policy alternatives in a more comprehensive way.

This paper investigates how interfuel substitution affects carbon dioxide (CO₂) emissions with a focus on the use of biodiesel blended fuels. The results show that the Divisia elasticity of diesel demand is the greatest because the transportation sector relies heavily on diesel. Also, while the own-price elasticity of each fuel demand is negative, the results reveal that diesel demand is more inelastic than the demand for gasoline and LPG. Moreover, gasoline is a substitute for diesel and electricity, and diesel is a substitute for LPG and a complement for electricity. Regarding the effects on carbon dioxide emissions, this paper computes the potential CO₂ emissions associated with interfuel substitution using the coefficients of CO₂ emissions. The results show that using biodiesel blended fuels contributes to reducing CO₂ emissions, but it appears that the price-induced interfuel substitution is a main factor affecting CO₂ emissions.

우수저류시설 사업은 일자리 창출을 위한 "녹색뉴딜사업" 추진방안 중 "대체수자원확보 및 친환경 중소댐 건설" 과제의 핵심사업으로 선정('09년)되어 추진하고 있는 사업으로 최근 기후변화에 의해 빈번하게 발생되는 국지성 집중호우에 의한 침수피해로부터 국민의 생명과 재산을 보호하고, 저류된 빗물을 대체 수자원으로 활용하기 위함이다. 그러나 국내의 우수저류시설 사업은 현재 시행 초기단계로서 제반 설계 및 유지관리 기술이 부족한 실정이며, 이로 인해 실제 운영시 많은 시행착오가 예상된다. 또한 전문가에 의한 시설 설치후 운영 등의 현황 분석 및 사업효과 분석이 거의 이루어지지 않고 있다. 따라서 기설치된 우수저류시설을 대상으로 현지조사 및 담당자 인터뷰를 통하여 시설 설치와 운영, 모니터링 등의 분야에 대한 현 실태 및 개선방안을 제시하고자 하였다. 시설 설치 분야의 경우 지역에 따라 스크린내 부유물 제거를 위한 제진기 설치, 원격조정시스템의 효율성 증진을 위한 CCTV 설치, 저류지 및 하류부 홍수위를 고려한 수문 및 여수로 운영계획 수립, 여수로 말단 하천 합류부에 유속감소시설 설치가 필요한 것으로 조사되었다. 시설 운영분야의 경우 지역에 따라 초기 강우가 저류조에 직접 유입되지 않도록 횡월류 위어 설치, 유량 및 수문관련 DB 출력 시스템 보완, 연속강우를 고려한 시나리오 작성, 저류시설의 운영 매뉴얼 수립이 필요한 것으로 판단된다. 계측시스템 분야의 경우 수위계, 유량계, 유속계 증설 또는 보완이 필요한 것으로 판단되며, 대부분의 지역이 시설 설치에 따른 피해 저감효과 분석에 필요한 DB가 충분히 확보되지 않은 것으로 조사되었다. 현 상태에서 저류시설 설치 전 후에 따른 침수피해 저감 영향에 대해 정성적 분석을 실시한 결과 ${\bigcirc}{\bigcirc}$지구의 경우 호우사상이 유사한 2007년 태풍 "나리"와 2011년 7월 집중호우시의 침수범위를 비교할 때 시설 설치에 따른 홍수 저감효과가 높은 것으로 조사되었다. 조사 결과, 저류시설에 의한 침수피해 저감 효과가 높다는 것을 고려할 때 지역 특성을 고려하여 우수저류시설 운영에 필요한 수리구조물 설치 운영, 계측시스템 설치 및 운영매뉴얼을 수립하는 것이 반드시 필요할 것으로 사료된다.
