Purpose : The purpose of this study was to investigate the effect of the aquatic exercise program on lower muscle strength, balance and gait activity on 12 weeks aquatic exercise program in the elderly women. Methods : The Subjects in this study were 20 aged 70s who were long-term residents admitted to elderly nursing home of S, Gyeongsangnam province. They performed aquatic exercise programs 60-minute sessions, 3 times a week for 12 weeks. The physical evaluation was used for measuring lower muscle strength, balance activity was used for measuring balance testing, and gait activity was used for measuring gait velocity and maximal step length evaluation. All data were analyzed by paired t-Test by SPSS(version18.0). P-values of <.05 were considered significant. Results : Lower extremity muscle strength, static dynamic balance and gait activity were significantly increased both in the exercise group and between groups. Conclusion : This study suggests that aquatic exercise program has an effect on lower extremity muscle strength, balance and gait activity of the elderly women. Therefore, it is considered as a safe and helpful self-support activity for the elderly people.

Non-variceal upper gastrointestinal bleeding (NVUGIB) refers to bleeding that develops in the gastrointestinal tract proximal to the ligament of Treitz. NVUGIB is an important cause for visiting the hospital and is associated with significant morbidity and mortality. Although European and Asian-Pacific guidelines have been published, there has been no previous guidelines regarding management of NVUGIB in Korea. Korea is a country with a high prevalence of Helicobacter pylori infection and patients have easy accessibility to receive endoscopy. Therefore, we believe that guidelines regarding management of NVUGIB are mandatory. The Korean Society of Gastroenterology reviewed recent evidence and recommends practical management guidelines on NVUGIB in Korea.

The purpose of this study was to compare and analyzed the effects of teaching-learning behaviors and to examine the effect of teaching behaviors on the student’s formative evaluation to elementary physical education classes in Korea and Japan.Thirty physical education classes taught by 30 elementary school teachers(Korea 15 teachers, Japan 15 teachers) were studied for this purpose.In order to analyze the teaching behaviors were coded using the four categories of Takahashi's Observation Instrument 1991), and the student's learning behaviors coded using the Supervision Program Instrument Youn’s instrument(1991). Additionally, student's evaluation to physical education classes were assessed by employing the Formative Assessment Instrument{Takahashi et al., 1994).Main findings were as follows,First, the teachers of Korea would spent 36.1% of total classes time in monitoring, while those of Japan would spent 37.2% of total classes time in direct instruction, and the most outstanding thing was that a lots of time spent during students' activity time which placed at the highest rate in respective countries.Second, the data of Korea have shown that; direct instruction and management episode behavior had significant positive correlations with student s receiving information and management behavior.The data of Japan have shown that significant correlation between direct instruction and receiving information, and the student's waiting behavior had significant positive correlations with interaction and transition.Third, the data of Japan scored higher on 9 items than those of korea at the student evaluation lo physical education classes.It was recommended that additional studies be conducted to better understand and control the effects the arranged contrived on the teaching-Learning behaviors in physical education classes.

Eradication of Helicobacter pylori using first-line therapy is becoming less effective. Subjects who had been treated for H. pylori infection were prospectively enrolled through an on-line database registry from October 2010 to December 2012. Demographic data, detection methods, treatment indication, regimens, durations, compliance, adverse events, and eradication results for H. pylori infection were collected. Data of 3,700 patients from 34 hospitals were analyzed. The overall eradication rate of the first-line therapy was 73.0%. Eradication failure was significantly associated with old age, concomitant medication, and comorbidity. Regional differences in eradication rates were observed. The most common first-line therapy was proton pump inhibitor-based triple therapy (standard triple therapy, STT) for 7 days (86.8%). The eradication rates varied with regimens, being 73% in STT, 81.8% in bismuth-based quadruple therapy, 100% in sequential therapy, and 90.3% in concomitant therapy. The eradication rate in treatmentnaïve patients was higher than that in patients previously treated for H. pylori infection (73.8% vs. 58.5%, P < 0.001). The overall eradication rate for second-line therapy was 84.3%. There was no statistical difference in eradication rates among various regimens. H. pylori eradication rate using STT is decreasing in Korea and has become sub-optimal, suggesting the need for alternative regimens to improve the efficacy of first-line therapy for H. pylori infection.

Background/Aims: Although acid suppressants are widely used for the prevention or treatment of drug-induced upper gastrointestinal bleeding (GIB), evidence regarding the prevention of anticoagulant-related GIB is scarce. The aim of this study was to evaluate the protective effect of acid suppressants against anticoagulant-related GIB. Methods: A systematic review was conducted of studies that evaluated the protective effect of acid suppressants against anticoagulant-related GIB found in PubMed, the Cochrane library, Embase, and KoreaMed from the date of database inception to April 2018. Random effect model meta-analyses with sensitivity analyses were conducted. The methodological quality of each included publication was evaluated using the Risk of Bias Assessment Tool for Nonrandomized Studies. Publication bias was assessed. Results: In total, six nested case-control or cohort studies were identified and analyzed. Proton-pump inhibitors (PPI) had a protective effect against upper GIB in patients on dicumarinics (risk ratio [RR], 0.56; 95% confidence interval [CI], 0.38 to 0.83; I2, 0%); however, the histamine-2 receptor antagonist did not have the same effect (RR, 0.97; 95% CI, 0.52 to 1.81; I2, 0%). Acid suppressants did not have a protective effect against GIB in patients on dabigatran (hazard ratio, 0.78; 95% CI, 0.44 to 1.37; I2, 81.8%). Conclusions: The protective effect of PPIs against dicumarinics-related upper GIB was clear, while there was no evidence supporting the protective effect of acid suppressants against dabigatran-related GIB. However, in the absence of randomized trials demonstrating a lack of bias, solid conclusions cannot be drawn.
손실함수를 활용한 Grey Relational Analysis 기반 다특성 공정 최적화
김상부,박우재 한국품질경영학회 2019 한국품질경영학회 학술대회 Vol.2019 No.-
현대에는 제품 또는 서비스에 대한 고객의 요구사항이 점점 더 다양화되고 있으며, 다양한 고객의 요구를 동시에 만족하기 위한 방법론이 꾸준히 연구되고 있다. 특히 제조 공정의 최적 공정 조건을 구하는 문제에서 다특성 최적화 문제는 현재까지 여러 가지 방법이 고려되어 왔으며, 그 중 한 가지 방법이 GRA (Grey Relational Analysis)이다. GRA의 전형적인 절차는 (1) Grey Relational Generation, (2) Grey Relational Coefficient Calculation, (3) GRG (Grey Relational Grade) Calculation의 총 3단계로 구성되어 있다. 이 중 첫 번째 단계에서 다특성 요인들에 대한 영향을 동일한 범위의 척도 (CS, Comparability Sequence)로 변환하여 품질 특성별 값과 해당 특성의 목표값 간의 거리를 구하게 되는데 일반적으로 선형 관계식을 이용한다. 그러나 다구찌 손실함수를 통해 알려진 바와 같이 품질 특성 값이 목표값에서 멀어질수록 발생하는 품질 손실이 2차 함수 형태로 증가한다고 보는 것이 합리적이다. 따라서 이 연구에서는 다구찌 2차 손실함수를 이용한 GRA 기반 다특성 공정 최적화 방법을 제안하였다. GRA 절차 중 CS를 구할 때 망대, 망목, 망소 특성별로 다구찌 2차 손실함수를 활용하여 특성별 측정값이 목표값에서 멀어질수록 손실이 2차 함수 형태로 발생하는 것을 반영한 CS 산출 식을 제안하였으며, 이를 항공기 엔진 부싱의 연마 공정에 적용한 사례를 포함하였다.

A lot of management innovation strategies including Six Sigma which has been adopted in many Korean companies originate from the Western culture. It may take long time for the Korean companies that they change from their own traditional corporate culture to a new globalized one. There used to be some problems for the companies with Eastern cultural background to implement Western management innovation strategies and vice versa. In this study, Six Sigma and Toyota Production System which represent Western and Eastern management innovation strategies respectively, are compared and some suggestions are considered for the Korean companies to adopt the Western style management strategies.
