Purpose: Despite the numerous protocols and evidence-based guidelines that have been published, application of the therapeutics to eligible patients is limited in clinical settings. Therefore, a rounding checklist was developed to reduce errors of omission and the implementation results were evaluated. Methods: A checklist consisting of 12 components (feeding, analgesia, sedation, thromboembolic prophylaxis, head elevation, stress ulcer prevention, glucose control, pressure sore prevention, removal of catheter, endotracheal tube and respiration, delirium monitoring, and infection control) was recorded by assigned nurses and then scored by the staff for traumatized, critically ill patients who were admitted in the trauma intensive care unit (ICU) of Dankook University Hospital for more than 2 days. A total of 170 patients (950 sheets) between April and October 2016 were divided into 3 periods (period 1, April to June; period 2, July to August; and period 3, September to October) for the analysis. Questionnaires regarding the satisfaction of the nurses were conducted twice during this implementation period. Results: Record omission rates decreased across periods 1, 2, and 3 (19.9%, 12.7%, and 4.2%, respectively). The overall clinical application rate of the checklist increased from 90.1% in period 1 to 93.8% in period 3. Among 776 (81.7%) scored sheets, the rates of full compliance were 30.2%, 46.2%, and 45.1% for periods 1, 2, and 3, respectively. The overall mean score of the questionnaire regarding satisfaction also increased from 61.7 to 67.6 points out of 100 points from period 1 to 3. Conclusions: An ICU rounding checklist could be an effective tool for minimizing the omission of preventative measures and evidence-based therapy for traumatized, critically-ill patients without overburdening nurses. The clinical outcomes of the ICU checklist will be evaluated and reported at an early date.

Background: This study evaluated the accuracy of smoking habit from the data obtained from the medical records of lung cancer patients against the data obtained form face-to-face interview questionnaires Methods: The smoking habits of 225 lung cancer patients were categorized into never smoked, ex-smoker and current smoker in face-to-face interview questionnaire and medical record taken at the time of admission for a diagnosis. The overall agreement between two sources was evaluated. The factors affecting the disagreement between two sources and the level of data omission of the smoking habits in medical records were analyzed suing multiple logistic regression. Results: The smoking habit between two sources showed moderate overall agreement(Kappa $({\kappa})=0.60$). The lowest agreement was observed in the ex-smokers(${\kappa}=0.49$). Multivariate analysis revealed an age of 65 or older to be a statistically significant factor associated with the increasing disagreement risk compared with those 64 or younger (OR 3.02; 95% CI 1.58-5.80). The omission rate of smoking habits in the medical records was 18.2%. Adenocarcinoma was shown to be a statistically significant factor of associated with an increasing omission rate compared with squamous cell carcinoma (OR 3.00; 95% CI 1.19-7.59). Conclusion: The smoking habits obtained from medical record moderately reflect their true behavior. However, the smoking habit data from medical record should be used with caution when being used in a clinical study or cohort study of lung cancer.

This study investigated human error characteristics of the 42 fatal industrial accidents reported by staff members of Korea Industrial Safety Corporation. Various types of human error were judged to be primary contributing factors in about 74 percent of the cases. Most of human error made by involved industrial operators resulted from two types of mistakes: (1) mistake in judgement of work situation, and (2) omission in daily check. It was concluded that preparation/observance for work procedure manuals, danger predication training and enforcement/Education of daily check routine would be effective preventive tools for these types of human error attributable to fatal industrial accidents.

The programmable logic controller(PLC) programming has been manually carried out, which might cause the productivity decrease by omission and repetition of instruction. Recently, the knowledge-based automatic programming system is introduced. In the system, input/output(I/O) addresses are input by user. In this study, we developed the prototype system for automatic I/O addressing using knowledge-based technology, With the developed system, the PLC addressing task can he consistently and effectively performed.

목적 : 본 연구의 목적은 기질적 조음장애 중 운동구어장애자의 유형에 따른 음운변동 패턴을 연구하여 각 집단만의 신경학적 손상으로 인한 조음운동 패턴을 분석하고자 하는데 있다. 운동구어장애자의 조음 오류에 대해서 SDO(substitution, distortion, omission) 분석적 접근을 하는 것이 일반적이며 따라서 음운변동 분석을 함으로써 이들의 오류패턴의 유형을 찾고, 언어중재 시에 이들의 조음기관 관련 근운동의 훈련을 보다 체계적으로 실시할 수 있을 것이라고 본다. (중략)

The producer's to tolerance concept (in contrast to the consumer's tolerence) fellows naturally from the notion of continuous loss function Emerging producer tolerance methodology has proceeded without benefit of carefully defined assumptions. We rectifg this omission and consider the process mean deviation. Then develope the models for which determine the tolerenes in cases of the-nominal-the-best, the-smaller-the-better and the-larger-the-better. Finally the numerical examples are Presented to illustrated these results and also the sensitivity analysis to apprehend the changes of loss tolerances varying with mean is presented.

오늘날 매우 널리 사용되는 TCP/IP 프로토콜은 많은 보안적 흠을 가지고 있다. 시퀸스 번호를 스푸핑, 소스 번호를 스푸핑, 인증 공격 등 많은 류의 공격이 이런 홈을 통해서 행해지고 있다. 또한 근원적으로 패킷의 TCP헤더 필드의 포트 번호와 IP 헤더 필드의 주소 번호를 분석하여 포트번호와 IP번호를 알아내어 상대방을 공격한다. 이에 상대방으로부터 포트번호나 어드레스 번호를 은닉하거나 생략하여 전송하여 상대방이 패킷을 분석하기 어렵게 만들어 TCP/IP 패킷의 보호하고자 한다. 먼저 본 논문에서는 TCP 헤더의 Port field를 제거하기위한 수정된 TCP 연결설정의 메커니즘을 제시한다.

For the effective utilization of the fish resources in coastal regions, investigations on processing conditions of frozen-dried product, quality stability of the Product during storage, and utilization as a food material were carried out with the filefish, Navoden modestus. The processing condition was determined with the moisture content and texture of the product. The duality of the product was evaluated on chemical composition, rehydration capacity, TBA value, browning, omission test and sensory score. The conditions for the processing of frozen-dried filefish under the conditions of freezing temperature at $-10^{\circ}C$ and forced air thawing at $56{\pm}2^{\circ}C$ with a velocity of 1 m/sec were as follows : freezing temperature, $-10^{\circ}C$ : freezing time, 10 hours; thawing time, 2 hours ; and repeated number of freezing and thawing, 5 times. The yield, the condition of moisture and protein were $10.2\%,\;23.6\%\;and\;70.6\%$, respectively. The frozen-dried product packed with air and stored at room temperature showed no remarkable changes in TBA value, rehydration capacity, browning during the storage period of 90days. The frozen-dried filefish showed no remarkable differences in the taste, odor and texture, comparing with frozen-dried Alaska pollack on the market.

Background: Statistical analysis is essential in regard to obtaining objective reliability for medical research. However, medical researchers do not have enough statistical knowledge to properly analyze their study data. To help understand and potentially alleviate this problem, we have analyzed the statistical methods and errors of articles published in the Korean Journal of Pain (KJP), with the intention to improve the statistical quality of the journal. Methods: All the articles, except case reports and editorials, published from 2004 to 2008 in the KJP were reviewed. The types of applied statistical methods and errors in the articles were evaluated. Results: One hundred and thirty-nine original articles were reviewed. Inferential statistics and descriptive statistics were used in 119 papers and 20 papers, respectively. Only 20.9% of the papers were free from statistical errors. The most commonly adopted statistical method was the t-test (21.0%) followed by the chi-square test (15.9%). Errors of omission were encountered 101 times in 70 papers. Among the errors of omission, "no statistics used even though statistical methods were required" was the most common (40.6%). The errors of commission were encountered 165 times in 86 papers, among which "parametric inference for nonparametric data" was the most common (33.9%). Conclusions: We found various types of statistical errors in the articles published in the KJP. This suggests that meticulous attention should be given not only in the applying statistical procedures but also in the reviewing process to improve the value of the article.
