This paper develops a general methodology for evaluating inspection (mainly, safety inspection) policies, standard and regulations in a complex system with lots of components. Based on practically available data, this methodology enable planners and regulators to estimate the costs and effectiveness of different inspection policies when applied under different system working conditions. As main tools, the concepts of detection probability and earliness of detection are developed in this paper.

We consider a general queueing network with multi-server stations. The stations are under heavy traffics or moderate variable conditions. We develope an algorithm to determine the optimal loading policy, which minimizes the congestion in a network. Under more specified condition, majorization and arrangement orderings are established to compare, respectively, various loading and assignment policies. Implications of results are also discussed.

Traumatic diaphragmatic hernia is among the most uncommon conditions after severe trauma, and it is associated with high morbidity and mortality. The diagnosis is difficult and might be missed, but a multimodal investigation might help in terms of diagnostic yield. In this case report, we present a missed right diaphragmatic rupture 14 years after the trauma.

건설 산업은 다양하고 예측이 어려운 외부 요인에 노출되어 있기 때문에 클레임의 발생 가능성이 높다. 이러한 클레임은 그 준비 과정에서 많은 시간이 필요하고, 결과적으로 많은 비용을 소모하기 때문에 신속한 해결을 요하는 경우가 많다. 그러나 지금까지 클레임은 클레임이 발생한 상황에서 공기지연, 금액증가 등의 이유와 더불어 발주자 우위의 관습 하에서 향후 다른 사업을 발전, 진행, 수주하는데 있어서 방해가 되는 것으로 인식하여 좋지 않은 것, 있어서는 안 되는 것으로 인식되어 회피하려는 경향이 지배적이다. 그러나 클레임은 건설공사의 불확실성 상에서 불주자와 시공자의 이견이 발생한 경우 서로의 이익을 증진시키기 위한 것이다. 이렇게 클레임이 건설공사에서 필수 불가결한 것이라면, 이를 타당하게 혀결하기 위하여 클레임이 발생한 경우 어떻게 해결하는 것이 합리적인지 계약문서상에서 반드시 명시하여줄 필요가 있다. 따라서 본 연구는 우리나라의 국내 공공공사에서 일반적으로 사용하는 공사계약일반조건과 해외의 대표적인 계약문서들(FIDIC, AIA, CMAA)과 비교하여 공사계약일반조건 중 클레임의 발생가능성이 높은 변경에 관한 조항과 분쟁해결 조항의 개선방향을 제시하고자 한다.

This study conducted an analysis of the correlations among menopausal symptoms of middle-aged women, their exercise performance and subjective health conditions on those 417 middle-aged women aged 40-59 years, residing in Seoul and the Kyongki Province area, from December 6, 2000 through Jun. 20, 2001, using the SPSS 10.00 program. Resultant findings were revealed, as follows: 1. A difference was represented in general characteristics between menopausal symptoms of middled-aged women and variables such as satisfaction with life, sexual life, diseases, the presence or absence of surgical operations; a difference between exercise performance and variables such as age, the presence or absence of vocations, weight control, satisfaction with life, and sleep; and also a difference between subjective health conditions and variables such as weight control, satisfaction with life, diseases, and the presence or absence of surgical operations. 2. Furthermore, a difference was revealed between the levels of menopausal symptoms by exercise performance and variables such as mental and physical symptoms and psychological symptoms. 3. The group of good exercise performance showed higher subjective health conditions as to subjective health conditions by the levels of exercise performance. 4. The better their subjective health conditions, the lower their menopausal symptoms as to menopausal symptoms by subjective health conditions. 5. A negative relationship was disclosed between menopausal symptoms and exercise performance; a positive relationship between exercise performance and subjective health conditions; and a negative relationship between subjective health conditions and menopausal symptoms.

This study was designed to examine the educational conditions of a foodstylist and student satisfaction with the training. It looked at the educational conditions of the food-stylist department, one of relatively newly-emerging departments, and examined student satisfaction by each factor in order to have specific problem in the educational conditions. The purpose of this study was to maintain higher student satisfaction and to have competitive advantage over the other related departments. For the general information of respondents, most respondents said the monthly average income to be approximately 1.5 times higher than that of common workers in the country, showing that the food-stylist department is preferred by the class with economic ability. For admission motives, respondents used the information via mass communication when they choose it For general educational conditions, students have most satisfaction with the originality of department, at the score of 3.79, following by laboratory and vision in the order. The least satisfaction was in career guidance, reflecting that they have vague ideas where to work. For the theoretical course of study, it was found that ‘Introduction to Table Coordination’ had the highest satisfaction, 3.82, following by ‘Coloring’ and ‘Understanding on Oriental and Occidental Tablewares’ in the order. ‘Food and Beverage Service’ and ‘Public Health’ were found to have the least satisfaction, showing that those subjects do not cause any interest in terms of their property. For the satisfaction of practical training course, it was found ‘Cocktail Practices’, ‘Bakery and Confectionary Practices’, and ‘Understanding of Wines’ in the order, showing that practical subjects with high visuality have higher satisfaction. Further studies are necessary to examine the satisfaction with subjects from various classes, together with many course of study, and to develop statistical data that help us understand the needs of students more correctly for application.

Objective: This study was to perform to identify the distribution characteristics and related factors of work-related low back pain among manufacturing workers in Korea. Methods: We analyzed the third(2011) through sixth(2020) Korean Working Conditions Survey. This study examined changes in the prevalence of work-related low back pain among manufacturing workers and related factors, including demographic characteristics and working conditions. Results: The prevalence of work-related low back pain showed a general tendency to increase during the study periods except for the 5th wave. The prevalence of work-related low back pain was higher in women than in men. The prevalence increased with increasing age and decreased with higher educational attainment. This trend was observed in all survey waves. The prevalence ratios for work-related low back pain according to working conditions varied over the survey period. In general, workers with manual jobs, long working hours, and exposure to tired or painful postures showed relatively higher prevalence ratios than did their counterparts. Providing Information on health and safety, perception that work affects health, and experience of presenteeism were identified as influencing factors for work-related low back pain. Although the working environment is improving, work-related back pain is on the rise. A multifaceted study on risk factors for work-related low back pain is needed. Conclusion: Work-related low back pain is a significant factor affecting the working population's quality of life. The prevalence of work-related low back pain showed a tendency to increase during the study periods. A multifaceted study on risk factors for work-related low back pain is needed.

The calcaneal insufficiency avulsion fracture usually occurs in an area of fused apophysis in adults without significant history of trauma or overuse activities. It is an uncommon injury which has been described in patients with complicated diabetes, Charcot neuroarthropathy, amyloidosis with neuropathy, severe osteoporosis, and other conditions. Discussion of the issue of fracture location is still not sufficient. We report on a case of a 50-year-old male who experienced a non-traumatic diabetic calcaneal insufficiency fracture. Intraoperatively, a biopsy specimen was obtained from the exposed fracture site for histological study. We assume that the calcaneal fused apophyseal line is the weak point of failure due to various incomplete mixtures of trabecular bone, woven bone, and cartilaginous tissues, and may fail when repeated tensile stress is imposed.
