The short-term production planning of an automated manufacturing system is to determine the production rate of each part type or family of part types. The purpose of this paper is to develop an optimal algorithm for solving the short-term production planning problem while machine failures, repairs. and changes in demand requirements are anticipated. The problem is formulated by LP and it shows that the production surplus is approached or stays at the hedging point. In addition, the long-term average frequencies of set-us with relation to a multilevel hierarchical production planing scheme are considered An example to show the effectiveness of the algorithm is presented.

본 연구는 노인장기요양보험제도의 도입으로 공식적 보호가 확대되고 있지만 여전히 장기요양대상노인의 케어에는 비공식적 보호 욕구가 줄어들지 않고 있는 현상에 대해 효과적인 장기요양서비스 제공체계 고찰의 필요성에서 시작되었다. 따라서 본 연구의 목적은 장기요양대상노인의 비공식적·공식적 자원연계 유형을 도출하고 각 유형에 따른 서비스 만족도의 차이를 살펴봄으로서 효과적인 장기요양서비스 제공 모델을 발견하는 것이다. 이를 위해서 비공식적·공식적 자원연계 유형은 장기요양대상노인에게 15가지 케어관련과업을 제공하는 비공식적 보호제공자와 공식적 서비스제공자의 서비스 제공정도를 군집분석으로 구분하였고 각 유형에 따른 서비스 만족도의 차이는 다중회귀분석으로 분석하였다. 연구결과 비공식적·공식적 자원연계 유형은 가족수발 중심형, 상호 보완형, 과업 분리형, 공식적 수발 중심형으로 구분되었고 서비스 만족도가 가장 높게 나타난 유형은 상호 보완형 이었으며 이를 바탕으로 다음과 같은 점을 논의하였다. 첫째, 비공식적 보호와 공식적 서비스가 상호 보완적으로 제공되기 위해서는 공식적 서비스 제공체계에 비공식적 보호제공자의 역할을 결합시키는 노력이 필요하다. 둘째, 15가지 케어관련과업 중 개인적 및 일상생활지원 과업과 건강보호 과업은 서비스 제공자가 분리되어 있어 의료 및 장기요양서비스의 연계를 위한 통합적 케어 방안이 필요하다. 셋째, 공식적 서비스 제공자가 거의 모든 케어를 제공하는 공식적 수발 중심형은 상대적으로 서비스 만족도가 낮게 나타나 이에 대한 대책이 필요하다. 이상의 결과를 바탕으로 본 연구는 장기요양서비스의 효과성 향상을 위해서는 서비스의 양(量)과 질(質)적 차원에서 비공식적·공식적 자원연계 유형을 파악하고 서비스 제공 방안을 모색할 필요가 있다는 제언을 하였다.

Gastro-esophageal reflux disease (GERD) is a recurrent, long-term gastrointestinal condition characterised by the abnormal reflux of stomach contents into the esophagus. Heartburn is the most dominant symptom, which can be life long and can considerably reduce quality of life. The main goals of treatment are to alleviate symptoms and prevent relapses, esophageal stricture and adenocarcinoma. This paper presents a review comparing the effectiveness of omeprazole with Nissen fundoplication surgery for the treatment of GERD. Nissen fundoplication is more effective in controlling heartburn symptoms, healing esophagitis and preventing relapses than omeprazole. Quality of life, in terms of productivity and ability to work, is difficult to assess in the omeprazole group and, as a result, a comparison of this aspect is limited. Although fundoplication is expensive in the short term, it is more cost-effective than omeprazole. Nurses need to be aware of the effectiveness of omeprazole and fundoplication to provide patients with accurate information, which assists patients in decision making regarding treatment options.

Bioventing is commonly used for petroleum hydrocarbon (PHC) spills. This process provides better subsurface oxygenation, thus stimulating degradation by indigenous microorganisms. Therefore soil vapor monitoring points (VMPs) are extremely important in determining the potential effectiveness of bioventing and in long-term monitoring of bioventing progress. In this study in-situ soil gas monitoring well (GMW) was developed and presented the pilot test results which recover the contaminated site by bioventing method. The result of application was successful and it was expected that GMW developed could be applied to the evaluation procedure of bioventing effectiveness and long-term remediation potential.

본 연구의 목적은 노인장기요양보험에서 급여로 제공하고 있는 복지용구 이용만족도를 비교해 보고, 개선방안을 모색하는데 있다. 이를 위해 재가에서 복지용구 급여를 수급하고 있는 전국 노인 1,200명을 대상으로 설문조사를 실시하였다. 조사결과 전체 복지용구의 만족도 수준을 보면, 사용의 편리성이 3.43점으로 가장 높고, 다음으로는 기능성 및 효과성 3.33점, 안전성 및 견고성 3.29점, 성능대비 비용적절성 2.69점 순이었다. 한편, 4개 영역을 총화한 이용만족도는 3.19점이었다. 복지용구 이용만족도는 사용동기에 따라 통계적으로 유의미한 차이를 보이지 않았으며, 선택요인에 따라서는 통계적으로 유의미한 차이가 있는 것으로 나타났다. 따라서 복지용구 이용만족도 개선을 위해서는 복지용구 전문가의 상담 기능을 강화하고, 복지용구 이용 활성화를 위해 급여수준 및 범위를 확대하여야 한다. 또한, 지속적인 연구를 통해 복지용구별 합리적인 척도 개발과 평가방법이 마련되어야 한다.

Fabry disease is an X-linked disease caused by deficiency of the lysosomal enzyme alpha-galactosidase A. Affected males present anhydrosis, acroparesthesia and angiokeratoma, and subsequently cardiac, cerebral and renal complications are followed. Females and atypical variants show heterogeneous clinical symptoms. In 2001, two recombinant enzymes were approved for Fabry disease: agalsidase alpha and agalsidase beta. Since the introduction of enzyme replacement therapy (ERT), the number of long-term follow-up studies has been reported. Long-term ERT showed effectiveness on renal function in patients with chronic kidney disease, decrease or stabilization of left ventricular mass, and improvement of pain and quality of life. However, there were limited effects on cerebrovascular events and their mortality. Current literatures on the clinical effect of ERT have reported limited datain adult patients who have already advanced disease. Therefore, further study for pre-symptomatic patients and atypical variants is needed to verify the impact of ERT. This review summarized recent progresses in ERT and limitations of long-term effect of ERT in patients with Fabry disease.

경제성장과정에서 석면을 활용해왔지만, 석면이 치명적인 환경성질환을 유발하는 1급 발암물질로 지정되면서 전 세계적으로 엄격한 석면사용규제 조치를 실시하고 있다. 석면노출과 환경성질환의 발현 간에 수십 년에 걸친 장기 잠복기가 존재한다는 특성을 고려하여, 한국의 석면 소비량과 악성중피종 발병 간의 시차를 분석하고 장기관계를 추정한다. 이와 함께, 한국에 비해 상대적으로 석면규제가 오랜 기간 이루어지고 장기시계열 자료를 갖춘 영국과 미국을 대상으로 한 비교분석도 병행한다. 시차분석에서는, 3개 국가 모두에서 30년 이상의 장기시차가 존재할 때, 석면 소비와 악성중피종 발병 간의 교차상관성이 높은 것으로 나타난다. 또한 변수간 장기시차가 존재할 경우 석면 소비량과 악성중피종 발병 간에 장기균형관계가 존재한다. 그리고 시차분포모형을 활용한 결과, 석면 소비량이 장기시차를 두고 악성중피종에 유의한 정의 영향을 미치고 있다.

Purpose: In Japan, the Long-Term Care Insurance Act has stipulated visiting rehabilitation since 2000. This study aimed to identify the actual conditions of visiting rehabilitation in Japan through a literature review of reports published by the Japanese government. Methods: This literature review was conducted on eight articles among various government reports on the topic of the actual conditions of visiting rehabilitation. These reports were published by the Ministry of Health, Labor and Welfare of Japan based on their own investigations or reports from an external agency entrusted with the task, and were issued between 2000 and 2021. Results: The characteristics of the visiting rehabilitation offices, their number, manpower allocation, the number of users, and their visits to each office were identified. Also, the characteristics of the users, number of users, age and required degree of long-term care, causative disease, and required medical care were identified. To evaluate the actual status of the visiting rehabilitation service, the service use time, frequency, period of use, intervention by doctors and the degree of such intervention, therapist's service content, visitors' address before the use of the service, reason, and timing of the service introduction, evaluation of the service effectiveness, combination of services and transfer destination after termination, and status after service termination were checked. Conclusion: Based on the Japanese experience where visiting rehabilitation was introduced and applied to long-term care insurance, it would be meaningful to review the factors that required benchmarking among the Japanese service models while designing a similar model in Korea.

Purpose: This study aimed to develop and assess the impact of an integrated infection control education program on the awareness, attitudes, and performance of infection control among caregivers in long-term care facilities. Methods: Participants were recruited from two long-term care facilities with 25 caregivers in both the experimental group and the control group. This study used non-equivalent control group quasi-experimental pre-post design. The effectiveness of a developed Integrated Infection Control Education Program was evaluated based on infection control awareness, attitudes, and performance. Data were analyzed using SPSS/WIN 28.0 through descriptive statistics, chi-square tests, Fisher's exact tests, and independent t-tests. Results: There was a statistically significant difference in the degree of awareness (t=-5.00, p<.001), attitude (t=-4.91, p<.001), and performance (t=-6.66, p<.001) of infection control between the two groups. Conclusion: Given these results, the integrated infection control education program significantly improved infection control awareness, attitudes, and performance among caregivers in long-term care facilities. This study is noteworthy because it provided comprehensive education on infection control practices to caregivers in environments that are particularly susceptible to infections, especially following COVID-19. This educational program is actively utilized and validated in practice, it would enhance the infection control performance of caregivers, thereby reducing infection rates within facilities, shortening the length of stay for elderly residents in long term care facilities, and contributing to the reduction of healthcare costs.
