Purpose: This study utilized a nonequivalent control group pre-post test design to test the effects of foot massage on anxiety and sleep satisfaction response in preoperative patients undergoing abdominal surgery. Method: There were 40 subjects in the study (20 in the experimental group and 20 in the control group). The experimental group received foot massage once a day for 2 days before their operation. Data were analyzed with descriptive statistics including mean, percentage, Chi-square, and t-test. Results: There were significant differences between experimental group and control group in the level of the state anxiety, pulse rate, and sleep satisfaction. Conclusions: Foot massage was effective in reducing anxiety and improving sleep satisfaction in abdominal surgical patients before their operation. Thus, foot massage may be used as an independent nursing intervention. This intervention can be performed anywhere, requires no special equipment, is noninvasive, and does not interfere with patients' privacy.

V. parahaemolyticus is a species of gram- negative asperogenous rod which gives rise to gastroenteritis in man and widely distributed in Korea. In this study, the distribution of V. parahaemolyticus among sea water and various marine products in Inchcon during the period of July 1984 to August 1984 was studied. The following results were obtained: 1. V. parahacmolyticus were isolated from 16(15.4%) of 104 specimens of sea water and various marine products. 8 strains(11.0%) were from fish and marine products 3 (25.0%) from aquarium watar, 3 from chopping board 1 from sea water and 1 from sea water in basin. 2. Among the 14 strains tested, 10 were Kanagawa phenomenon positive and 4 were negative. 3. 16 strains were tested for K antigens and 3 were found to be $K_{17}$, 1 each of $K_{22}, K_{25}, K_{34}$ and $K_{57}$. 7 strains were not agglutinated with any K-type multiserum.

XML 트리 데이터들로부터 빈번 서브 트리들을 추출하는 기존 방법들은 복잡하고 다수의 입력데이터 스캐닝을 필요로 할 뿐만 아니라 빈번 서브 트리를 구하기 위해 에지 하나하나의 조인 작업을 필요로 하였다. 이는 결과적으로 많은 수행 시간을 요한다. 본 논문에서는 트리데이터를 레벨 별로 나누고 이를 마치 채로 거르듯이 필터링하여 특정 수치 이상의 출현 횟수를 가지는 노드들만을 남겨 빠르게 빈번한 서브 트리를 찾고, 이를 이용하여 XML 연관규칙들을 생성하는 방법을 제시한다. 제시된 방법을 위해서 PairSet 이라는 새로운 자료구조를 도입하였으며, 이를 이용하는 크로스필터링 알고리즘을 개발하여 제시하였다.

Pharmacokinetic drug interaction between phenytoin and diltiazem was investigated following i.v. administration concomitantly to rabbits. Diltiazem was coadministered at doses of 1, 2 and 3 mg/kg, respectively, with phenytoin (5 mg/kg) to rabbits. Plasma concentration and AUC of phenytoin were increased significantly, but volume of distribution and total body clearance were decreased significantly (p<0.05) at doses of 2 mg and 3 mg/kg of diltiazem. From the results of this experiment, it is desirable that dosage regimen of phenytoin should be adjusted and that therapeutic drug monitoring should be practiced for reduction of side or toxic effect when phenytoin should be administered with diltiazem in clinical practice.

In this paper, a new group sampling plan for the lot acceptance is proposed for the time truncated life test, which can be utilized when multi-item testers are implemented. The design parameters are found using the two-point approach such that the producer's and consumer's risks are satisfied simultaneously at the acceptable reliability level and the lot tolerance reliability level, respectively. The case of Weibull distribution is described to illustrate the procedure that can be used when the quality level is expressed by a multiple of the specified life. The advantage of the proposed plan is demonstrated by comparing with the existing plan in terms of the sample size required. The tables are constructed and some examples are given to illustrate the procedure developed here.

Giant cell tumor (GCT) of the spine is a rare benign tumor, but can be aggressive and can exhibit a high local recurrence rate. Furthermore, GCT of the upper thoracic spine may pose diagnostic and management difficulties. Here, we report a rare case of GCT of the upper thoracic spine with soft tissue extension to the spinal canal. The patient was managed by decompressive laminectomy and posterolateral fusion followed by an injection of polymethylmethacrylate into the vertebral lesion. The patient recovered clinically and showed radiological improvement after surgical treatment without tumor recurrence at his last follow-up of postoperative 7 years. We present this unusual case of GCT and include a review of the literature.

Purpose: This study was a qualitative study done to investigate the experience of role conflict by physician assistant nurses. Methods: The basis for this study was qualitative research using the phenomenological method. Research participants were 10 physician assistant nurses. Data collection methodology was in-depth interviews. The interviews were conducted 1 to 2 times and each interview lasted within the range of 45 minutes to 2 hours. The data collection and analysis were carried out simultaneously and the Colaizzi (1978) methodology was adopted for data analysis. Results: The results showed 46 significant statements, 13 meaningful statements, 7 themes, and 3 clusters of themes. The 3 clusters of themes were: 'Identity conflict', 'Relationship role conflict' and 'Institutional role conflict'. Conclusion: The findings from this study suggest that legal status guarantees have to be prepared in order to resolve the role conflict of physician assistant nurses.

In this study the magneto hydrodynamic (MHD) micro polar fluid flow of a viscous incompressible fluid past a porous medium in the presence of chemical reaction is considered. This work is devoted to investigate the Soret effect and Electromagnetic radiation effect and analyze analytically. In the energy equation the applied magnetic field strength and in the concentration equation the Soret effect are incorporated. The basic PDE (partial differential equations) are reduced to ODE (ordinary differential equations) using non dimensional variables. Then the analytical solution of the dimensionless equations are found using perturbation technique. The features of the fluid flow parameters are analyzed, discussed and explained graphically. The graphical solutions are found using MATLAB R2019b. Skin friction coefficient at the wall, Couple stress coefficient at the plate and the local surface heat flux are also thoroughly examined. Overall, this study sheds light on the complex interplay between physical parameters in the behavior of MHD micro-polar fluid past a porous medium in the presence of chemical reaction.

Obesity is closely related to chronic diseases and cancer. The present case report aims to discuss the anti-obesity treatment strategy and the evaluation of the clinical progress in a patient with obesity and concurrent fatty liver disease. Following five months of treatment with liraglutide and rosuvastatin, the patient had a weight reduction of 3 kg (4.7%), a decrease in fasting blood sugar by 42 mg/dl (26.6%), a decrease in low-density lipoprotein cholesterol by 82 mg/dl (60.2%), and decrease in alanine transaminase. This case report documented the treatment of a patient with common chronic diseases encountered in the outpatient setting. Based on the therapeutic effects documented in clinical and laboratory indices, the anti-obesity treatment plan significantly aided in managing chronic diseases.

Isometric array grammar is one of the simplest model to generate picture languages, since both sides of its production rule have the same shape. In this paper, we have introduced isometric fuzzy regular array grammars to generate isometric fuzzy regular array languages and discussed its closure properties. Also, the relation between isometric fuzzy regular array grammar and boustrophedon fuzzy finite automata has been discussed. Moreover, we study the relation between two dimensional fuzzy regular grammars with returning fuzzy finite automata and boustrophedon fuzzy finite automata. Further, the hierarchy results of these three classes of languages have been discussed.
