Purpose: The purpose of this study was to explore socio-demographic, clinical and psychological factors associated with medication adherence among patients with chronic heart failure (CHF). Methods: In a cross-sectional survey, 133 patients with CHF who had visited a clinic located in Seoul participated. Medication adherence (MA) was measured using a single item visual analogue rating scale (VAS). Barriers and attitudes toward adherence, and depression were measured using a structured questionnaire. Medical records were reviewed to identify their clinical characteristics. Multivariate logistic regression was performed identify factors affecting medication adherence. Results: About one third of participants (31.1%) reported their MA as 100%. Overall attitudes on MA were highly positive and 49 (36.8%) of participants were depressive. MA was associated with significantly barriers (p<.001), attitudes (p<.001), age (p<.001), and duration of disease (p<.001). The high adherent group had significantly less barriers than other groups (OR=.389, p=0.02). Conclusion: This study indicates that barriers and attitudes toward MA were the most important factors affecting their adherence to HF medication. To improve MA for patient with CHF, the nursing strategies which can lead poor adherent patients to their optimal level should be developed.

정부에서는 2001년 5월에 실무적용을 위한 ${\lceil}$건설정보분류체계 구축을 위한 연구${\rfloor}$ 를 추진하여 대${\cdot}$중분류 등을 제시하였고, 그 결과 '통합건설정보분류체계 적용기준'을 건설교통부 공고로 2001년 8월에 발표하였다. 그러나 구축된 '통합건설정보분류체계'는 건설공사에서 실무활용이 미흡한실정이다. 일반적인 시설물과는 다르게 교육시설물의 경우 적용기준이 혼재되어있는 문제가 이다. 더욱이 2005년부터 교육시설물에 BTL 민간투자 사업이 시행되면서 유지관리시업무기준이나 비용계상에 대한 기준을 '통합건설정보분류체계 적용기준'에 적용할 경우 경계를 명확하게 하기 어려운 실정이다. 따라서 본 연구는 기존의 유지관리 비용분석으로 사용되었던 공종(Work)중심의 시설물 유지관리를 분석하고 이를 보완하기위해 공간(Space), 부위(Element)중심 유지관리 분석을 하여, 효율적인 유지관리 체계정립을 위한 분류의 기준을 제안하였다.

The purpose of this study is to improve the calculation method of the software operation pricing proposed by the software business price calculation guide from 'input manpower method' to 'rate calculation method'. The software operation pricing of the input manpower method is not objectively calculated in the domestic IT outsourcing situation where the statistical data based on the activity based estimating is insufficient and it is decided by agreement between the owner and the client. In addition, there was no standard for adjusting the productivity according to the characteristics of the operation service. In order to improve this, an operational correction factor item that can affect the software operation productivity was selected based on foreign and domestic standards, and it was confirmed through the first questionnaire to IT operation managers. In order to determine the level of difficulty of the fixed operational correction factors, the operational correction factor using AHP technique was confirmed through a second questionnaire for pairwise comparison. The operational difficulty calculation table was developed with reference to COCOMO and ITIL standards. Finally, we propose a new pricing scheme that reflects the operating rate. Regression analysis was carried out by collecting the data of the domestic public institutions on the estimated cost and the actual cost calculated from the new rate method software operation pricing. The results of the regression analysis show that the estimated cost and the actual cost are related to each other. Mean magnitude of relative error(MMRE) and PRED[25] analysis were added for accuracy analysis. MMRE and PRED also showed satisfactory results, confirming the possibility of replacing the rate method software operation pricing.

This study was conducted at five Ethylene Oxide(EO) sterilizing processes in hospitals located in Seoul from August 8 to August 30, 1994. The main purposes of this study were to assess the TWA(Time Weighted Average) and short term exposures to EO and to evaluate factors affecting EO concentrations in sterilizing room. Results are summarized as follows. 1. The TWA concentrations of the sterilizing operators ranged from <0.005ppm to 3.04ppm and those of two sterilizing rooms out of five exceeded 1ppm, the Korean and ACGIH standards. 2. When the door of the sterilizer is opened at the end of the sterilization cycle, the short term concentrations of operators ranged from <0.005ppm to 11.4ppm, and those of three sterilizing room out of five exceeded 5ppm, the ACGIH short term exposure limit(STEL). The short term concentrations of area samples ranged from 0.24ppm to 49.2ppm and those of four sterilizing room out of five exceeded 5ppm. 3. Factors affecting EO exposure level were aeration type, the location of storage site for sterilized item, amount of gas, use period of sterilizer(p<0.005). 4. Following recommendations are suggested to minimize exposure to EO. The use of EO gas should be reduced by using another available sterilization methods, and the sterilizers and gas tank storage site should be isolated from, other work areas. Combination of local and general ventilation system should be installed. Metal carts or baskets for sterilization load should be used, and work environment and medical monitoring should be performed regularly.

Advance development of the internet has brought significant changes to the distribution structure of the fashion industry, resulting in decreased sales in Road shops and sudden growth of online fashion specialty shopping malls. As detailed analysis on internet fashion shopping malls is necessary in order to make a future projection on changes in the fashion industry, this thesis aims to study the color, fabric / pattern, silhouette, item / detail, image, etc of 2008 S/S apparel fashion style sold in the top ten shopping malls, selected in terms of sales volume and awareness. The results were further analyzed to characterize each individual shopping malls, upon which the design was compared with the five main trends for the season provided by three fashion research agencies in order to study the level of trend acceptance. Studies showed that 'Romantic Sake' trend was most widely accepted, followed by 'Eco Nature' which most reflected the characteristics of Spring. 'Modern Ethenic' trend was most aggressively accepted at more upscale shopping malls targeting older demographic, while " Play Urban' was highly accepted by shopping malls specializing in young casual. Due to the disadvantage of not being able to try on the items before purchase, styles following the 'City Luxe' trend featuring fitted suits showed the lowest trend acceptance. Amongst the design elements, color was most widely accepted.

The purpose of this study was to identify the relationship between the levels of job satisfaction and self-evaluated foodservice quality of dietitians in elementary schools. Out of 130 questionnaires distributed to the elementary school dietitians in In-cheon, 127 were returned and analyzed (98% response rate). The questionnaire included two multiple-item scales for measuring job satisfaction and foodservice quality, respectively. All the items in the scales were coded 1 to 5 for certainly no, no, neutral, yes, and certainly yes and grouped by using factor analyses. Most of the responding dietitians were working for schools in urban areas and had independently-managed on-site kitchens. The 23 items measuring job satisfaction were grouped into 4 factors: Job Duty, Job Condition, Physical Work Environment, and Organizational Environment. The satisfaction score was the highest for Organizational Environment with a value of 3.38 and the least for Physical Work Environment with a value of 2.08. The 22 items measuring foodservice quality were grouped into 5 factors and the mean scores of the levels of Cleanliness, Internal Food quality, External Food quality, Intangible Service Environment and Tangible Service Environment were 4.20, 3.89, 3.54, 3.45 and 2.64, respectively. The levels of job satisfaction and foodservice quality were positively associated with a correlation coefficient of 0.288 (p < 0.01). In particular, the level of job satisfaction was positively associated with foodservice quality in the aspect of Cleanliness, Internal Food Quality, and Intangible Service Environment. The results show that improving dietitians' job satisfaction could contribute to increasing the levels of foodseivice quality of elementary schools.
