The article analyzes the impact of factors affecting the internal control system of chemical enterprises in Vietnam, providing more empirical evidence on factors affecting the system of internal control. Research data is collected in the form of face-to-face interviews and email interviews with managers and employees working in different positions, managers at all levels, chief accountants, and accountants of 52 chemical enterprises in Vietnam. The survey results collected 310 questionnaires. After eliminating the invalid questionnaires due to many blank cells, the authors chose to use 297 questionnaires. Quantitative research was carried out with SPSS 25 software. Research results show that Business Strategy, Organizational Structure, Organization's perception of the instability of the external environment, and Organizational culture are the factors that positively affect the internal control system of chemical enterprises. This can be explained that, for chemical enterprises, Business strategy, Organizational structure, Organization's perception of the instability of the external environment, and Good organizational culture will positively impact the internal control system of chemical enterprises. Based on the research results, the authors have proposed recommendations to enhance the effectiveness of the internal control system of chemical enterprises in Vietnam, thereby contributing to improving the performance of enterprises in the chemical Vietnamese.

The increase in the rearing intensity of pigs has caused deterioration in the pig house's internal environment such as temperature, humidity, ammonia gas, and so on. Traditionally, the widely used method to control the internal environment was through the manipulation of the ventilation system. However, the conventional ventilation system had a limitation to control the internal environment, prevent livestock disease, save energy, and reduce odor emission. To overcome this problem, the air-recirculated ventilation system was suggested. This system has a semi-closed loop ventilation type. For designing this system, it was essential to evaluate the ventilation rates considering the pressure loss of ducts. Therefore, in this study, pressure loss calculation and experiment were conducted for the quantitative ventilation design of a semi-closed loop system. The results of the experiment showed that the inlet through which external air flows should always be opened. In addition, it was also found that for the optimum design of the semi-closed loop ventilation system, it was appropriate to install a damper or a backflow prevention device rather than a ventilation fan.

Peritoneal dialysis (PD)-related peritonitis is a major cause of injury and technique failure in patients undergoing PD. Aeromonas hydrophila is ubiquitous in the environment, and is a Gram-negative rod associated with infections in fish and amphibians in most cases; however, it can also cause opportunistic infections in immunocompromised patients. We report a case of A. hydrophila peritonitis in a 56-year-old male on automated PD. Peritonitis may have been caused by contamination of the Set Plus, a component of the automated peritoneal dialysis device. Although Set Plus is disposable, the patient reused the product by cleansing with tap water. He was successfully treated with intraperitoneally-administered ceftazidime and has been well without recurrence for more than 2 years.

Purpose: The purpose of this study was to identify the effects of nurse's internal marketing on job satisfaction, turnover intention, and customer orientation. Method: The subjects were 559 nurses were working in 3 general hospitals. The data were collected from October 20 to November 15, 2006. For data analysis, descriptive statistics, Pearson correlation coefficient, stepwise multiple regression were used. Results: The mean score of the total internal marketing was 2.68, communication 3.03, vacation and suspension from office 2.64, education and training 2.60, reward system 2.56, work environment 2.53, and employment benefits 2.38, total job satisfaction was 2.96, turnover intention was 3.10, and customer orientation was 3.76. 'Internal marketing', and total subcategories of internal marketing were positively related to job satisfaction. 'Internal marketing', and total subcategories of internal marketing were negatively related to turnover intention. 'Internal marketing', 'communication', 'vacation and suspension from office', 'education and training', and 'work environment' were positively related to customer orientation. Conclusion: Through this results, to increase job satisfaction and customer orientation and to decrease turnover intention, it is necessary to concentrate on improving internal communication and reward system in the internal marketing strategy.

자가치유란 시스템에 정의된 제약사항들을 평가하고 위배 시에 적절한 전략을 적용하는 방법론이다. 오늘날 복잡해져가는 컴퓨팅 환경에서 자가치유를 위해 시스템에 발생한 문제를 스스로 인식하는 능력을 부여하는 연구가 중요한 이슈가 되고 있다. 그러나 대부분의 기존연구들은 목표시스템을 자가치유하기 위해 자가치유 개발자들이 제약조건을 모델링하고 분석해야 하는 노력이 크다. 따라서 본 논문에서는 자가 치유 기법을 기반으로 시스템의 내외부 문제 결정을 자동화하는 방법론을 제안한다. 본 방법론은 1) 목표 시스템의 설계단계에서 생성된 설계모델들로 시스템을 명세화하고, 2) 명세화 된 내용을 기반으로 시스템의 내외부 대한 공통 제약 사항을 자동 생성한다. 3) 자동 생성된 내부 상태 규칙을 통해 컴포넌트간의 의존관계를 해석하여 4) 생성된 공통 제약사항과 분석된 연관성 모델을 코드로 변환하고 문제결정 수준을 결정한다. 5) 문제결정 수준을 기반으로 시스템의 내외부 상태를 모니터링을 하고, 비정상 상태 발생 시 전략을 적용한다. 이러한 자동화된 제안 방법론의 특징을 통해 자가 치유 개발자의 분석의 부하를 줄이며, 나아가서는 시스템의 외적 환경뿐 아니라 내부 상태 문제에 관한 비정상적인 동작을 신속하게 정상적인 상태로 회복하고, 시스템 다운과 같은 고장 횟수를 줄이는 것이 가능해 진다. 본 논문에서는 평가를 위해 제안 방법론을 비디오 회의 시스템에 적용하고 기존 방법론과의 자가치유를 위한 활동을 비교하여 그 유효성을 확인한다.

The aim of this paper is to show the daylight environment of a light pipe system according to sun movement. A light pipe system has been mounted on the roof of the windowless full scale model: the solar spot has diameter of 0.65m and is 1.3m long, giving an aspect ratio of 1:2. The full scale model was installed on the rooftop of the SHINAN apartment in Yongin city that has no obstructions against sunlight. The test room is equipped with sensors for the measurements of the internal illuminance and has an area of 6m(W)$\times$6m(D)$\times$4m(H). The system has been monitored with a data-logger to evaluate the cumulative distribution of illuminance on a floor-plane from 16th, April to 29th, May, 2008 over one month and selected clear sky condition. For the daylight performance of floor area, the totally 49 measuring points has been used to determine the internal illuminance and an HP datalogger(HP34970A) records the measurements for one consecutive month. The horizontal external illuminance has been measured with two outdoor sensors. This paper presents the results of monitoring light pipe system with internal/external illuminance ratio and cumulative frequency distribution of floor-plane illuminance are discussed The results show that lightpipe is proficient device for introducing daylight into the building. However It provided different daylight indoor environment with wide or narrow Interquatile range of illuminance, internal/external illuminance ratio and cumulative frequency distribution according to solar positions under suuny sky condition. For more achieving the improvement of lightpipes also include energy savings, user visual comfort with various indicators; seasonal solar height, room and lightpipes geometries.

Purpose - This study examined the effects of CRM success factors on business performance and customer performance, and the effects on job performance and customer performance through internal member satisfaction by considering of technology, organizational environment and customer relationship factors in CRM success factors from banking sectors. Research design, data, and methodology - An online questionnaire was conducted to 251 employees in banking sectors. The data were analyzed by SPSS 22.0 and Amos 21.0. CRM success factors, internal member satisfaction, job performance, and customer performance were analyzed by descriptive statistics and Pearson's correlation analysis. The bootstrapping in structural equations was conducted to verify the mediating effect of internal member satisfaction. Results - Internal members' satisfaction had a positive effect on job and customer performance. It mediated the relationship between organizational environment, customer relationship factors and job performance. It also mediated the relationship between organizational environment and customer performance. Conclusions - If internal members' relationship with customers is improved by the members' satisfaction, customer retention, customer satisfaction, and work performance will be achieved. The stability and usability in CRM system support jobs effectively, but the internal members did not feel their job satisfaction. Thus, they did not show a positive effect on job and customer performance.
