목적: 외래에 내원하는 암환자들을 대상으로 암성통증의 조절에 있어서 $Ultracet^{(R)}$의 효과와 안전성에 대해 알아보고자 하였다. 방법: 암으로 진단을 받고 통증 조절을 목적으로 $Ultracet^{(R)}$을 투여한 61명의 환자를 대상으로 통증조절의 정도와 통증이 환자의 삶의 질에 미치는 영향에 대한 평가를 위해 Korean version of Brief Pain Inventory를 이용하였다. 약물의 안전성은 복용 후 나타나는 부작용 정도에 의하여 평가하였다. 결과: 대상환자의 평균연령은 59.9세였고 성별분포는 남자가 34명, 여자가 27명이었다. 환자의 진단은 폐암, 위암, 육종, 대장암, 췌장암, 자궁 경부암, 두경부암, 그리고 림프종 등의 순이었다. 대상환자에서 가장 심했을 때의 통증 정도는 $Ultracet^{(R)}$을 사용하기 전후에 유의한 감소를 보이지 않았으나($5.18{\pm}1.41\;vs.\;4.82{\pm}1.94$; P=0.113), 가장 약했을 때의 통증 정도($1.2{\pm}1.05\;vs.\;0.87{\pm}1.35$; P=0.038), 환자가 느끼는 통증의 평균 정도($3.65{\pm}1.01\;vs.\;3.13{\pm}1.73$: P=0.022)와 바로 지금 느끼는 통증정도($3.63{\pm}1.25\;vs.\;2.85{\pm}1.94$; P=0.003)는 유의하게 감소되었다. $Ultracet^{(R)}$의 사용으로 인한 부작용은 전반적으로 경미하여 2도의 오심과 구토 각 1예와 1도의 변비, 소양증, 안면 홍조가 각각 1예씩 관찰되었으나 3도나 4도의 독성은 관찰되지 않았다. 결론: $Ultracet^{(R)}$은 외래환경에서 암환자의 통증조절에 있어서 안전하게 사용할 수 있는 비교적 효과적인 약물로 생각된다. Purpose: We aimed to investigate the efficacy and side effects of $Ultracet^{(R)}$ in relieving cancer pain in setting. Methods: Sixty-one cancer patients over 18 years old, who had cancer pain with or without medication, were enrolled. Pain and other variables were evaluated before and after treatment with $Ultracet^{(R)}$ for 2 weeks, using Korean version of Brief Pain Inventory. Results: Of 61 patients with assessable efficacy data, the maximum pain intensity(PI) experienced in a day were $5.18{\pm}1.41\;and\;4.82{\pm}1.94$, before and after treatment with$Ultracet^{(R)}$ respectively (P=0.113). The minimum PI experienced in a day were $1.2{\pm}1.05\;and\;0.87{\pm}1.35$, before and after treatment with $Ultracet^{(R)}$, respectively (P=0.038). The average PI experienced in a day were $3.61{\pm}1.01\;and\;3.15{\pm}1.73$, before and after treatment with $Ultracet^{(R)}$, respectively (P=0.022). The current PI were $3.63{\pm}1.25\;and\;2.85{\pm}1.94$, before and after treatment with $Ultracet^{(R)}$, respectively (P=0.003). Regarding the quality of life, only mood changed for the better in 49 patients who were treated with $Ultracet^{(R)}$ alone ($1.98{\pm}1.73\;and\;1.35{\pm}1.15$, before and after treatment respectively; P=0.046). There were five (8.2%) adverse events associated with $Ultracet^{(R)}$ treatment. Conclusion: $Ultracet^{(R)}$ seems effective and safe in ambulatory patients with cancer pain.

추천 시스템은 고객의 데이터를 이용하여 개인 맞춤화된 상품을 추천한다. 추천 시스템은 협업 필터링, 콘텐츠 기반 필터링 그리고 이 두 가지를 합친 하이브리드 방법의 세 가지로 크게 나누어진다. 이 연구에서는 딥러닝 방법론에 기초한 오토인코더를 이용한 추천 시스템에 대한 소개와 그 모형들의 비교 연구를 진행한다. 오토인코더는 데이터 행렬에 0이 많은 경우의 문제를 효과적으로 다룰 수 있는 딥러닝 기반의 비지도학습 모형이다. 이 연구에서는 세 개의 실제 데이터를 이용하여 다섯 가지 종류의 오토인코더 기반 모형들을 비교한다. 처음의 세 개 모형은 협업 필터링에 속한 모형이고 나머지 두 개의 모형은 하이브리드 모형이다. 실제 데이터는 고객의 평점 데이터이고, 대부분의 평점이 없어서 희박성 비율이 높다는 특징이 있다. Recommender systems use data from customers to suggest personalized products. The recommender systems can be categorized into three cases; collaborative filtering, contents-based filtering, and hybrid recommender system that combines the first two filtering methods. In this work, we introduce and compare deep learning-based recommender system using autoencoder. Autoencoder is an unsupervised deep learning that can effective solve the problem of sparsity in the data matrix. Five versions of autoencoder-based deep learning models are compared via three real data sets. The first three methods are collaborative filtering and the others are hybrid methods. The data sets are composed of customers' ratings having integer values from one to five. The three data sets are sparse data matrix with many zeroes due to non-responses.

The purpose of this study was to investigate the status and views on the dental team composition and works, the experience of a dental manpower shortage and opinions on the solution. The subjects were 313 dentists and dental hygienists. The mobile questionnaires were conducted on the status of dental team composition and works, the experience of a dental manpower shortage and opinions on the solution. There was no big difference between the current dental team composition and ideal composition ratio, and dentists answered that it would be more ideal to reduce dental hygiene and increase nurse assistant when the working dentist was 3~5. 85.6% of the dentists and 56.4% of the dental hygienists had difficulty in employing the dental auxiliary personnel. The difficulty level was 8 out of 10 points among dentists and 5.7 points among dental hygienists. 91.1% of the dentists and 95.5% of the dental hygienists agreed on the necessity of expanding the dental hygienist's work. The dental works were temporary crown making and setting, surgical operation assistance, and overall dental assistance. Based on the results of this study, it is necessary to continuously make efforts to communicate with the dental personnel in Korea to solve a lot of problems such as the job assignment, the dental personnel policy and system, and the work environment.

공급체인관리와 관련된 성과가 실제 기업의 재무성과에 미치는 영향을 파악하기 위하여 본 논문에서는 자동차산업, 의류산업, 유통산업을 대상으로 공급체인관리 성과와 재무성과를 비교분석하였다. 공급체인관리 성과를 파악하기 위하여 Cash-To-Cash Cycle Time이 사용되었고, 2004년부터 2008년까지의 5년간 선택된 상장기업들의 재무제표를 분석하여 그 영향을 분석한 결과 공급체인관리의 수준을 파악하는데 사용되는 Cash-To-Cash Cycle Time이 자동차 산업과 의류산업에서는 재무성과와 양의 상관관계가 있는 반면 유통산업에서는 음의 상관관계가 있는 것으로 파악되었다. 상세분석결과 자동차 산업과 의류산업에서는 재고수준을 늘려 매출을 늘리는 전략이 재무성과에 긍정적인 영향을 미치는 것으로 분석되었고, 유통산업에서는 재고수준을 낮추고 효과적 공급체인 및 물류관리를 통해 매출채권회수기간을 단축시키는 것이 재무성과에 긍정적인 영향을 미치는 것으로 나타났다. 따라서, 산업 및 기업의 특성에 따라 재고수준, 매출채권회수기간, 매입채무회수기간으로 구성되는 공급체인관리지표 Cash-To-Cash Cycle Time을 적절히 관리하는 것이 중요한 것으로 판단된다. The purpose of this paper is to identify the relationship between supply chain management and finance performance metrics. Cash-to-cash (C2C) cycle time is chosen as a SCM-related metric. In this paper, C2C cycle time of the three selected industries are investigated with data of sample companies listed on Korean stock market for a period from 2004 to 2008. The key finding is that a positive correlation is detected between C2C cycle time and the metrics for automobile and fashion industries, while a negative correlation is investigated for retail industry. Further study shows how each component of C2C cycle time affects on the performance metrics. For automobile and fashion industries, it is suggested to generate more sales and keep enough inventories, instead of decreasing the C2C cycle time. For retail industry, it is advised to decrease inventory level and to ask faster collection, as well as to make later payment. It is noticeable that what is generally hypothesized for C2C cycle time, ‘the shorter the C2C cycle time, the more profitable a company is,’could be only accepted for retail industry. For automobile and fashion companies, it is more important to keep enough inventories and to increase sales revenue than cutting down the C2C cycle time with the purpose of improving liquidity.

Purpose: The purpose of this study was to develop a Korean nursing work environment scale for critical care nurses (KNWES-CCN) and verify its validity and reliability. Methods: A total of 46 preliminary items were selected using content validity analysis of experts on 64 candidate items derived through literature reviews and in-depth interviews with critical care nurses. 535 critical care nurses from 21 hospitals responded to the preliminary questionnaire from February to March 2021. The collected data were analysed using construct, convergent and discriminant validities, and internal consistency and test-retest reliability. Results: The 23 items in 4 factors accounted for 55.6% of the total variance were identified through item analysis and exploratory factor analysis (EFA). EFA was performed with maximum likelihood method including direct oblimin method. In the confirmatory factor analysis, KNWES-CCN consisted of 21 items in 4 factors by deleting the items that were not meet the condition that the factor loading over .50 or the squared multiple correlation over .30. This model was considered to be suitable because it satisfied the fit index and acceptable criteria of the model [x² =440.47 (p<.001), CMIN/DF=2.41, GFI=.86, SRMR=.06, RMSEA=.07, TLI=.90, CFI=.91]. The item total correlation values ranged form .32 to .73 and its internal consistency was Cronbach's α=.92. The reliability of the test-retest correlation coefficient was .72 and the intra-class correlation coefficient was .83. Conclusion: The KNWES-CCN showed good validity and reliability. Therefore, it is expected that the use of this scale would measure and improve nursing work environment for critical care nurses in Korea.

Objectives: The purpose of this study was to investigate the current status of dental hygiene curricula related to clinical practice in Korea. Methods: Clinical work included the categories ‘history taking, infection control, oral prophylaxis, preventive treatment, education/counseling, radiography/reading, assisting/cooperation, impression/bite registration, anesthesia, etc.’, and 66 works were finally selected based on the frequent tasks of dental hygienists. The subjects were made to answer nine questionnaires. Results: It was found that the theory and practice of the main works operated quite differently in lectures and practice in each school. All types of practice were applied to all schools in the case of ‘scaling’. The evaluation of clinical practice was also found to be very different from school to school. Conclusions: For dental hygienists to establish expertise in clinical practice and promote quality improvement, it is necessary to develop a core curriculum focusing on clinical practice. The standardized curriculum should be improved to an efficient and competency-centered one defining clearly the role of dental hygienists considering the needs and importance of clinical practice.
