  • 본 논문에서는 LNG저장탱크의 통압제어 안전관리 시스템에 대한 연구결과를 제시하고 있다. 통합제어 및 안전관리를 효과적으로 진행하기 위한 새로운 통합관리 시스템은 내부탱크로부터 유출되는 가스나 초저온 액체(LNG)에 의한 안전성과 누출문제를 제어하기 위해 온도, 압력, 진동과 같은 신호를 검지하고, 종합적으로 분석하여 시스템의 안전성을 확보할 수 있도록 개발된 것이다. 효율성과 안전성 향상측면에서 LNG저장탱크의 저장용량 증가경향과 최근에 발생된 저장탱크의 고장사례 고찰을 통하여, 기존의 측정장치와 안전장치는 개량되고, 새로운 기술개발이 필요하다는 것을 강조한다. 따라서 본 연구에서는 초대형 LNG저장탱크의 제어와 안전관리를 위해 새로이 개발된 통합제어 안전관리 시스템을 제시하고 있다. 이 시스템에서는 기존의 측정 및 안전장치에 대한 통합과 연계성 및 성능을 향상시키고, 특히 저장탱크 구조물의 변위량을 측정하여 안전성을 확보할 수 있도록 기능성을 새로이 추가하였다. 본 연구에서 개발된 통합제어 안전관리 시스템에 프로세스 통합관리 시스템(PIIS)을 연계하여 사용한다면, LNG 저장탱크의 안전성, 효율성, 생산성은 획기적으로 향상될 것이다.

  • Purpose: The purpose of this study was to investigate the relationship between obesity, body image perception, and weight control for obesity management in adult women. Methods: The subjects of this study were 3,617 women aged over 19 years, who participated in the Seventh Korea National Health and Nutrition Examination Survey 2016. Data were analyzed through complex sampling design data analysis. Results: Right body image perception according to obesity was apparent between 70.6-81.7% of women and 76.5% of women with abdominal obesity perceived that they were normal. Obese women performed more weight control than non-obese women. Women with only abdominal obesity performed less weight control than non-obese women, and 47.3% of them performed weight control. Women who perceived themselves as obese performed more weight control than women who perceived themselves as non-obese (odds ratio, 2.08; confidence interval, 1.69-2.57), but body mass index was not observed to be associated with weight control. Conclusions: Education on abdominal obesity should be provided to increase awareness about abdominal obesity and its effective management, especially in women with only abdominal obesity. In addition, interventions for right body type perception should be provided for proper weight control along with prevention and management of obesity.

  • This study empirically investigated the relationships among inter-organizational cost management (IOCM), cooperation with suppliers, information exchange between partners, inter-organizational learning, control integration, and the supply-chain performance of a firm. The results showed that the adoption of IOCM positively affects the collaboration between buyers and suppliers, which also leads to the increased information flow between them. According to the results of this study, it was found that inter-organizational information flow causes inter-organizational learning, and this learning contributes to the improved supply-chain performance. In this study, the positive effects of the cooperation with suppliers through IOCM on the control integration in supply-chains were not empirically confirmed. However, the impact of IOCM on control integration was significant and positive. Finally, the fact that the enhanced control integration can improve the supply-chain performance of a firm was empirically demonstrated.

  • This study examines the effect of independent commissioners and the Audit Committee on internal control disclosure and its implications for earnings management in the banking industry listed on the Indonesia Stock Exchange for the period 2016-2018. In this study, a purposive sampling technique was used, combined with two multiple regression analysis models. The final sample for this study comprised 30 companies over the three years of observation, such that there were 90 observations in total. This study indicates that independent commissioners, as measured by their composition, do not affect the disclosure of internal control. However, as measured by the number of members, the Audit Committee had a positive effect on internal control disclosures. This study also indicates that the disclosure of internal control as measured by the Internal Control Disclosure index affects reducing the negative practice of earnings management. This study proves that the Audit Committee's role is very dominant in assisting the Board of Commissioners in supervising internal control. This has implications for reducing earnings management practices. However, the Independent Commissioner's role in the Indonesian banking industry has not been optimal in carrying out the supervisory function in this study.

  • This paper is to present design principle and operation strategy of acceptance control chart by the use of OC-Based sampling inspection for continuous data. The unified control limits for acceptance control chart when considering both APL(Acceptable Process Level) and RPL(Rejectable Process Level) are proposed. The control limits can be also extended to the acceptance control chart with unknown process standard deviation.

  • Purpose: The purpose of this study was to examine the effects of education regarding postoperative pain management provided for nurses as well as patients on related factors of pain management, including nurses' knowledge and attitude of postoperative pain, and the level of pain that patients felt after surgery. Method: A quasi-experimental research design was used in this research. Twenty-one nurses currently working in general surgery units and 32 patients who were taking on abdominal surgery in A university hospital were participated in this study. The three week-educational program of postoperative pain management including lecture, quiz, poster and discussion was provided for nurse participants. The postoperative pain management education for each patient was provided one day before his/her own operation for 20 minutes with the pamphlet developed by researchers. For assessing the effects, nurses' knowledge and attitude about pain management, patients' postoperative pain, pain control barriers, and satisfaction of pain management were measured. Results: The nurses' knowledge about pain management and the patients' satisfaction of pain management in the experimental group were higher than in the control group. The patients' postoperative pain in the experimental group was lower than in the control group. Conclusion: With the above results, the postoperative pain management education could be an effective nursing intervention for pain management of patients who were taking surgery.

  • The fuel cell system has inherent limitation such as slow response time and low fuel economy especially at the low power region, and thus, the battery system has come to be used to compensate for the fuel cell system. This type of hybrid configuration has many advantages, however, the energy management strategy is essentially required. The work in this paper presents survey on recent power management strategies for fuel cell hybrid electric vehicles. For three power management strategies: basic control method. object function-based control method, and fuzzy logic-based control method. each strategy is reviewed and discussed with other strategy.

  • As agricultural companies encounter number of risks in their business, it is very important to control the risks for their stable management. So we examine the agricultural business risks and propose the risk management strategies for the agricultural companies. For these purpose, we analyze the agricultural business risks with which agricultural companies are confronted, and propose the agricultural companies' the risk management strategies. The results of this study are as follows : First, Changing the risk environment of agricultural business, we have to realize the importance of the agricultural risks and risk management in it. Second, When we choose the risk management strategies which are risk retention, risk avoidance, risk control, risk transfer and insurance, etc., we should always consider the frequency of loss and the severity of loss. Third, If we don't control the agricultural risks, we will be in a position to very difficult situation. So, Agricultural companies should lead to stronger effort to manage the risks for their stable business.
