정보접근, 획득, 이용자와 정보시스템과의 상호작용과 관련된 내용 중심으로 연구된 이용자 연구는 변화된 정보환경에서 정보획득과 공유행위를 포함한 정보행위 관점에서 연구할 필요가 있다. Wilson의 정보행위 개념을 적용하여 도서관과 인터넷 환경에서 이용자 정보획득과 공유행위의 요구 및 동기, 과정의 내용을 분석하기 위해 질적 연구와 양적 연구의 통합적 접근을 시도하였다. 통합적 분석을 토대로 정보서비스 개선방안을 제시하였다. Study on users which was done centering information approach, acquisition and interoperability between users and information systems need to be studied in the perspective of information behavior including information acquisition and sharing behavior in the changing information environment. In order to analyze users' information acquisition and sharing behavior's demands, motives and processes in libraries and internet environments, integrated approach of both qualitative and quantitative study were tried by applying Wilson's information behavior concept. Plans for the improvement of information services were suggested on the basis of integrative analysis.

화력발전소에서 사용되는 석탄중의 회성분 분석은 노내에서의 슬래깅성(slagging), 파울링성(fouling), 마모성 및 집진성 등을 예측하거나 구성성분에 따라 석탄의 적정 혼탄비율을 결정하는데 유용하게 사용되므로 매우 중요하다. 현재 ASTM에서는 석탄회 분석법은 용융법에 의해 전처리한 후 AAS(Atomic Absorption Spectrometer)로 분석하는 것으로 규정하고 있으나, 이 분석법은 시료의 수가 많은 경우에 상당한 시간과 노력을 필요로 하여 한전의 모든 발전소의 분석업무를 담당하고 있는 본 연구실의 경우에는 적합하지 않다. 따라서, 정확하고 신속한 분석방법을 개발하기 위하여 시료를 LiBO$_2$를 사용한 용융법과 마이크로파을 이용한 용해법으로 전처리를 한 다음 ICP를 사용하여 분석한 결과와 석탄회 시료를 투명한 pellet으로 만들어 XRF로 분석한 결과를 비교${\cdot}$검토하였다. 이번에 확립된 두 가지 전처리법에 의한 ICP 분석과 XRF 방법 모두 석탄회의 주요 성분을 분석하는 데 유용하게 사용할 수 있는 분석방법임을 확인할 수 있었고, 각각의 방법은 장${\cdot}$단점을 가지고 있으므로 사용목적에 따라 적절히 활용될 수 있다. The analysis of coal ash is very important to predict some factors, such as slagging and fouling in the boiler, and to determine optimum mixing ratios of the each coals used. In ASTM, the analysis of coal ash is clarified to use lithium metaborate (LiBO$_2$) as a fluxing agent and then to analyze the pre-treated samples using AAS. However, it takes too much time and efforts to analyze many samples by ASTM method, as a result, this method is not proper in our laboratory in charge of analyses of all power plants. So we tried to establish more convenient and accurate analytical method of coal ash by 3 different methods which are 2 different pre-treatment methods (fusion dissolution and microwave digestion) and XRF analysis method using a clear pellet. Although all 3 methods can be utilized to analyze the major elements of coal ash, each method has its own characteristics, therefore, each method should be chosen according to its own purpose.

Purpose: To report a case of central serous chorioretinopathy development after glaucoma filtering surgery and spontaneous resolution in a patient with a history of central serous chorioretinopathy in the contralateral eye. Case summary: A 46-year-old male with a history of chronic uveitis in both eyes presented with uncontrolled intraocular pressure (IOP) in his left eye. Initial IOP was 34 mm Hg in his left eye. On preoperative evaluation, central serous chorioretinopathy, which was diagnosed in another clinic 1 month prior, was observed in his right eye. Slightly pale optic disc and retinal nerve fiber layer defects were noted in the left eye. However, macular abnormalities were not observed in the left eye. Trabeculectomy and peripheral iridectomy using mitomycin C were performed in the left eye. The patient was prescribed triamcinolone 8 mg daily for 4 days to reduce the post-surgical inflammation. On postoperative day 4, IOP in the left eye was 7 mm Hg and newly developed central serous chorioretinopathy was noted. On follow-up, IOP was maintained at 7-10 mm Hg and central serous chorioretinopathy disappeared 7 months postoperatively. Conclusions: When clinicians consider performing an ophthalmological procedure in a patient with a history of central serous chorioretinopathy in the contralateral eye, careful observation of central serous chorioretinopathy development is recommended.J Korean Ophthalmol Soc 2014;55(12):1895-1900

The goal of this study is to examine municipality comprehensive plans by recognizing the problem that adverse impacts of urban regeneration impede the sustainability of specific renewal project. 10 major cities in Korea that are experiencing urban decline were chosen for the study area and plan evaluation indexes were adopted based on the sustainable urban regeneration principles in terms of environmental, social, and economic aspects. Plan evaluation was conducted by employing the content analysis method and developed assessment indexes for three sectors (factual basis, goal/objective, and policy/action) of plan. The findings show that policies, such as 'expansion of parks in urban area,' 'pedestrian-oriented street improvement project,' and 'countermeasures for local industry revitalization,' should be fundamentally included in adopting sustainable urban regeneration plans. Plan scores regarding sustainable urban regeneration had an insignificant relationship with the status of administrative district and plan adopted year. This is because metropolitan municipalities, including Ulsan, Daejeon, and Daegu, received relatively low plan score compared to local governments like Goyang and Suwon. Also, Daegu and Suwon, which established their comprehensive plan in 2018 obtained lower score than Seoul and Incheon, where its plans were created before 2015. Evaluation protocol and indexes that were suggested in this study can be used while reorganizing each locality's comprehensive plan, and thus, play as one of major bases in preparing future sustainable urban regeneration projects.
