An economic evaluation was conducted using cost-benefit analysis for an integrated service platform of open access research articles. The data needed for benefit measurement were collected by conducting a series of surveys to service beneficiaries, including 1,313 academic researchers, 49 bio-industry researchers, and 102 researchers in various industries. Cost-benefit analysis and sensitivity analysis were conducted after estimating the total costs for system construction and operations, anticipated direct and indirect benefits. With respect to the cost-benefit analysis limited to direct benefits, the estimated benefit was KRW 82 billion, which is about 14 times of the total costs for eight years of the entire business period. With respect to the cost-benefit analysis for both direct and indirect benefits, BCR was estimated to be about 98.9 and NPV to be KRW 538.8 billion, indicating that economic feasibility of the project was sufficiently secured. The results of this analysis may help securing the investment to the integrated service platform for OA research products, and the benefit estimation model developed in this study would be utilized as an assessment tool during the rest of this project.

본 연구는 우리나라 성인들의 공공도서관 이용을 예측할 수 있는 요인을 규명하기 위한 목적으로, 공공도서관 방문빈도가 그 개인의 인구사회학적 특성, 그가 이용하는 개별 공공도서관의 서비스 자원 투입 및 산출 특성, 그리고 거주지의 기초 및 광역 지방자치단체의 공공도서관 투자 수준과 어떤 관계를 갖고 있는지 살펴보았다. 자료수집을 위하여 우리나라 인구의 성별, 연령, 지역적 분포 등을 고려한 유층표집을 적용하여 대한민국 전역에 거주하는 18세 이상 일반성인 1,000명을 대상으로 전문사회조사기관의 온라인패널을 통해 2014년 3-4월 33일간 웹설문조사를 실시하였고, 2013년 국가도서관통계를 분석하였다. 연구결과 우리나라 성인들의 공공도서관 방문은, 인구가 많은 대도시 지역에 거주하는 독서량이 많은 개인이 일상적으로 쉽게 접근할 수 있는 중소규모의 새로 건립된 공공도서관이 있고, 이용자 개개인의 요구에 부응할 수 있는 인적 자원이 충분하게 확보되어 있을 때 더 빈번히 이루어지고 있는 것으로 나타났다. 본 연구결과를 토대로 향후 공공도서관 건립 및 서비스 개선을 위한 정책적 제안을 제시하였다. The purpose of this national study is to identify the factors affecting the public library use among the Korean adult population. The study constructed a model of three types of factors to explain the frequency of public library visits: an individual's socio-demographic characteristics, input and output measures of the local library, and the community size and library investment of the local government. The data were collected from both a national representative sample of 1,000 adults of 18 years old or above who participated in a web survey and the 2013 National Library Statistics of Korea. It was found that a more frequent public library visit occurred when a person who read more and lived closer to the library, which was newly established in a small to medium-sized scale, who lives in a city with a greater population and with more library staff members serving a fewer patrons. Implications for future public library constructions and for public services were suggested based on the study findings.

Ultra-thin aluminum (Al) and tin (Sn) films were grown by dc magnetron sputtering on a glass substrate. The electrical resistance R of films was measured in-situ method during the film growth. Also transmission electron microscopy (TEM) study was carried out to observe the microstructure of the films. In the ultra-thin film study, an exact determination of a coalescence thickness and a continuous film thickness is very important. Therefore, we tried to measure the minimum thickness for continuous film (dmin) by means of a graphical method using a number of different y-values as a function of film thickness. The raw date obtained in this study provides a graph of in-situ resistance of metal film as a function of film thickness. For the Al film, there occurs a maximum value in a graph of in-situ electrical resistance versus film thickness. Using the results in this study, we could define clearly the minimum thickness for continuous film where the position of minimum values in the graph when we put the value of Rd3 to y-axis and the film thickness to x-axis. The measured values for the minimum thickness for continuous film are 21 nm and 16 nm for sputtered Al and Sn films, respectively. The new method for defining the minimum thickness for continuous film in this study can be utilized in a basic data when we design an ultra-thin film for the metallization application in nano-scale devices.

능동소음제어를 이용한 건설현장의 소음관리모델 개발 - 도심지 공사현장을 중심으로 -

권나현,박문서,이현수,안요섭,김선우,Kwon, Nahyun,Park, Moonseo,Lee, Hyun-Soo,Ahn, Joseph,Kim, Sunwoo 한국건설관리학회 2014 한국건설관리학회 논문집 Vol.15 No.2

건설현장에서 발생하는 소음으로 인하여 많은 사람들이 고통을 겪고 있고, 그로 인하여 민원과 분쟁이 증가하고 있다. 이러한 민원은 사업의 지연 및 중단, 배상액 지불과 같은 시간적, 경제적 손실을 초래하므로 엄격하게 관리되어야 한다. 이와 같은 추세에 따라 정부는 기존 방음벽 중심의 소음정책에서 탈피하여 발생원 중심으로 소음을 관리하기 위해 노력하고 있다. 그러나 건설소음은 일시적이고, 불규칙적으로 발생하며, 건설장비 자체의 소음레벨이 높기 때문에 쉽게 제어되기 어렵다. 또한 최근 선진국을 중심으로 사람들에게 쉽게 인지되지는 않지만, 고주파 소음과 마찬가지로 인체에 정신적, 신체적 피해를 주는 저주파 소음에 대한 연구를 활발히 진행하고 있다. 그러나 기존의 수동적인 소음관리방식으로는 고주파 소음을 저감하는데 효과가 있을 뿐, 저주파 소음을 저감하는데는 한계가 있다. 그러므로 본 연구는 건설현장에서 발생하는 소음을 저감하고, 기존의 수동적인 소음관리방식의 한계점을 보완하기 위한 방법으로 능동소음제어를 이용하여 건설현장에서 발생하는 소음을 저감하기 위한 관리모델을 제안하는 것을 목적으로 한다. 이를 위하여 시뮬레이션 실험을 수행하였고, 능동소음제어의 건설현장 적용성을 검토하였다. 본 논문은 능동소음제어를 통하여 건설현장에서 발생하는 소음을 저감하고, 소음피해로 인한 민원과 분쟁을 최소화하는데 일조할 수 있을 것이라 기대한다. Recently, many people have been damaged seriously by construction noise. Accordingly, there have been increased the complaints and disputes. These complaints should be controlled strictly. Otherwise there could be delays or stops of project and losses of time and money. For this reasons, the Korean government is trying to convert from depending on the soundproof wall to noise control system focusing on noise sources. However, it is difficult to control the noise which is generated from construction site because construction equipment has very high noise level and construction noise generates temporarily and irregularly. Also, people do not know how much low frequency affect human body adversely because they cannot perceive low frequency noise easily. Hence, recently developed countries have conducted the research on the low frequency noise which damages on human physically and mentally. However, passive noise control is insufficient to reduce the low frequency noise, but only efficient to lower the high frequency noise. Thus, an approach which can complement limitations of passive noise control is needed. Therefore, the purpose of this research is to suggest the noise management model using active noise control on construction site. Also, ANC simulation has been conducted to examine its applicability on construction equipment. As a result, it is expected that there will be a reduction of construction noise and demages, as well as both mental and physical damages.

Objectives : The purpose of this study is to investigate the therapeutic effects of oriental medical treatment and oriental-western medical treatment on Bell's palsy. Methods : From 1st June, 2006 to 31th August, 2007, 30 Bell's palsy patients who visited the Facial palsy center at East-West Neo Medical Center within 7days of onset and treated for more than 4weeks were randomly divided into two groups. Group A was treated with oriental medical therapy(Acupuncture, Herb, Physical therapy) and Group B with both oriental and western medical therapy(Acupuncture, Herb, Physical therapy, Administration of prednisone). We evaluated the treatment effect of each group with the House-Brackmann Gross Grading System before treatment, after 1week, 2weeks, 3weeks and 4weeks of treatment. Results : After 1week of treatment, Group A showed better performance compared with Group B. After 3weeks and 4 weeks of treatment, Group B showed better performance than Group A. Conclusions : These results proved that combination treatment of oriental and western medicine was more effective than just oriental medical treatment in long term treatment of Bell's palsy. But we discovered that there were no significant differences between the two groups.

윤리적 소비 경험에 대한 현상학적 고찰: 생태요소를 도입한 협동주택 구매자를 대상으로

권나현(Nahyun Kwon) 한국NGO학회 2013 NGO연구 Vol.8 No.2

This is a study to understand the purchase experience of people who live in ecological cooperative housing by the qualitative method of phenomenological study. Three subjects were interviewed in order to explore experiences of ecological cooperative housing and the meaning of the ethical consumption to the subjects. The interviews took place during Aug. 3 to 10, 2013. Each interview took 60~90 minutes each, including the validation process of repeating each question and asking the subjects’ consent on their answers. The interviews were recorded by the mobile phone and transcribed with the computer word program. Repeated reading and extracting meaningful statements were done to develop themes on the subjects experiences of ethical consumption by the Colaizzi s method of the phenomenological study. The themes are: happy experiences, daily pleasures, convenience, feelings of communication, feelings of growth and development, feelings of consolation and healing, feelings of being eco-friendly, feelings of being respected, feelings of sharing, and feelings of being restricted. The limitation of this study is that there was only a small number of subjects. Is is suggested to repeat the study with more subjects. 본 연구는 생태요소를 도입한 협동주택 구매자를 대상으로 윤리적 소비 경험에 대한 현상학적 고찰이다. 서울 마포구 성산동 인근 성미산 주변에서 자생한 성미산 마을 안에 있는 협동주택 소행주(소통이 있어 행복한 주택) 1호 거주 자를 대상으로 접촉 가능한 거주자, 세 명을 심층 면접하였다. 협동주택에 거주 하는 것은 협동주택을 어떤 형태로든 구매한 것이고, 협동주택을 구매한 것은 윤리적 소비를 경험한 것이기 때문에 연구대상으로 삼았다. 협동마을 거주자가 경험한 윤리적 소비와 심리적 경험에 대한 연구문제의 현상학적 탐구를 위해 실시한 심층 면접은 녹음하였고, 녹음을 전사(transcript)한 뒤에, 반복하여 읽으 면서 의미있는 자료를 도출하고, 의미 있는 자료를 동일 의미 군으로 묶어 범주 화하는 콜라이찌(Paul Colaizzi)의 방법으로 분석하였다. 그 결과 10개 범주를 도출하였는데, 이들 범주는 행복한 경험, 일상의 즐거움, 편리함, 소통의 느낌, 성장하고 발전하는 느낌, 위안/치유의 느낌, 자연과 친한 느낌, 존중받는 느낌, 나눔의 느낌 그리고 구속의 느낌이었다. 본 연구는 지금까지 시도되지 않은 윤리적 소비에 대한 경험을 생태요소를 도입한 협동주택 구매자를 대상으로 현상 학적으로 고찰한 결과, 10가지 범주를 도출한데 의의가 있다. 대상자 접촉의 어려움으로 인하여 연구 대상자가 3명으로 제한된 것은 연구의 제한점으로 남는 다. 또한 타당화 과정을 2, 3회기의 면접에서 확보하려고 하였으나 참여자들이 현실적 어려움을 토로하여, 1회기를 하는 대신 면접시간을 길게 하여 각 피면접자에게 구술 내용에 대해 면접자가 요약정리하고, 동의 및 부연설명의 과정 으로 대신하였다. 본 연구에서도 연구 참가자들의 살아있는 생생한 경험과 그의미를 도출해 낼 수 있었으나 한 건물로 이루어진 협동주택의 거주자를 대상 으로 삼았기 때문에 앞으로는 다른 협동주택의 거주자를 대상으로 다양성을 확보하여 반복 연구를 제안한다.

Background: Idiopathic calcinosis cutis (CC) is currently sub-classified as tumoral CC, sub-epidermal calcified nodules, idiopathic CC of the scrotum, and milia-like CC. This sub-classification system is obscure and can be confusing at times. Objective: This study was designed to characterize the clinical and histologic features of idiopathic CC, to evaluate the adequacy of the current sub-classification system, and to propose a new sub-classification system. Methods: Thirty patients with idiopathic CC were sub-classified according to the Lever classification and the Walsh and Fairley classification and were also categorized based on the type of the primary lesion. Results: Idiopathic CC lesions were most common on the buttock (n=7), followed by the scrotum (n=5), arms and legs (n=5), hands and feet (n=4), inguinal area (n=3), ears (n=2), neck (n=2), trunk (n=1), and face (n=1). With the Lever classification, twenty-three of 30 cases were categorized as unclassified. With the Walsh and Fairley classification, twenty-three cases were categorized as unclassified, whereas with our new classification system, we managed to classify all cases as either nodular or papular calcification according to the type of the primary lesion. Conclusion: In this study, we identified a common location and the primary morphological features of idiopathic CC. Our findings suggest that our new sub-classification system based on the type of the primary lesion would be useful. (Korean J Dermatol 2011;49(10):907∼914)
