This study aims to contribute to the early detection of occupational fraud in the Korean financial industry by analyzing fraud symptoms. Firstly, the definition, cause of occupational fraud, and fraud symptoms were discussed through literature review. Secondly, survey data were collected from the employees of the financial industry such as bank, insurance, and securities companies to conduct statistical analysis. The result of analysis showed that the symptoms of 'excessive stock investment' and 'unsettled life style' were statistically significant predictors of fraud detection experience. Plus, 'tips and complaints' were the most frequent method for detecting occupational fraud in the Korean financial industry. The financial institutions can minimize the loss of occupational fraud by early detection through educating their employees and vendors on these important symptoms of occupational fraud.

자연재해 중 홍수는 전 세계적으로 가장 큰 인적 및 물적 피해를 발생시키고 있으며, 지구온난화로 가속화되고 있는 기후변화는 더욱 극심한 호우와 태풍 현상을 야기하고 있다. 최근 우리나라에서도 2020년 장마는 역대 가장 긴 장마로 기록되는 등 변화된 기상현상으로 인해 홍수피해의 빈도와 강도가 지속적으로 증가하고 있다. 따라서, 이상기후로 인한 홍수피해에 대한 대비와 적응을 위해 위험도 평가, 예·경보시스템, 대피체계 등과 같은 비구조적 대책의 수립이 필요하다. 그 중 홍수피해에 대한 위험도 평가는 과거 홍수피해자료를 바탕으로 지역별 피해양상이나 상대적인 피해위험도를 파악할 수 있으므로 홍수피해 저감대책 수립에 중요한 비구조적 도구로 인식되고 있다. 이에 따라 본 연구는 행정구역별 과거 강우특성 및 홍수피해자료를 분석하여 강우조건에 따라 예상되는 홍수피해위험도를 평가하는 방법을 제안하고자 한다. 이를 위해 먼저, 국민재난안전포털에서 제공하는 재해연보에서 행정구역별 최근 20년 동안의 호우 및 태풍으로 인한 피해자료를 수집하여 인적 및 물적 피해특성 자료를 구축하고, 홍수피해가 발생한 기간에 대해 기상청에서 제공하는 시강우량 자료를 수집하여 홍수피해 사상별 다양한 강우특성자료를 구축한다. 구축된 자료를 이용하여 행정구역별 강우-피해 상관분석을 수행하고, 회귀분석 과정에서 이상치가 존재할 경우 회귀모형의 적합도를 향상시키기 위해 이상치를 제거하고 분석하여, 회귀식의 결정계수 및 유의성 검정결과를 바탕으로 3가지 원인별(호우, 태풍, 종합), 2가지 홍수피해별(인적, 물적) 강우-피해 최적 회귀함수를 선정한다. 최종적으로 강우조건에 따른 홍수피해 규모를 예측하고, 이를 통하여 행정구역별 상대적인 홍수피해위험도를 평가한다. 본 연구를 통해 행정구역별 강우조건에 따른 예상 홍수피해위험도를 분석하여 홍수피해에 대한 저감대책 수립에 기초자료를 제공할 수 있을 것으로 기대된다.

Crew fatigue has been recognized as a major cause of maritime accidents. Systematic study on crew fatigue has a direct impact on the human factor, but the various measures being taken to prevent human error account for most of the causes of marine accidents situation are still insufficient. In this study, 128 people who have a variety of career and job types boarded the T/S Hanbada were analyzed the changes of fatigue during the 87-days a Maritime Silk Road Sailing Expedition. Crew fatigue was measured by period of time onboard classified as mental, physiological and physical changes through survey responses and individual interviews of nurses. Also, it was identified the fatigue factor through quantitative statistical analysis. As a result of repeated measures analysis of variance for the changes of fatigue in position and gender criteria in accordance with boarded period, the position-specific analysis was that Professor Rating group has appeared to feel more mental and physical fatigue than the student population. Also, the results of fatigability about the sex-specific analysis have been found that women feel more physical fatigue than men.

Natural gas is an explosive fluid and can cause severe human/material damage when buried high-pressure pipeline is failure, and there have been reported cases of considerable human life damage to actual buried pipeline failure. In domestic cases, the length and duration of pipeline operating are short due to rapid growth. Therefore, it is a fact that the establishment of effective accident data is insufficient for the cause of the accident. In order to systematically construct an accident database, the operation history of natural gas pipeline is longer than domestic, and the cause and frequency analysis of recent natural gas pipeline related accidents occurred in overseas major countries with a long pipeline network was conducted. Then, after grasping the trend of occurrence frequency by incident cause, we tried to establish the foundation for securing the stability of the domestic high-pressure gas transport pipeline network.

Background : Recent discoveries on the physiology of an erection have demonstrated that the organic causes of impotence are more common, and psychogenic impotence is correspondingly less common than was formally believed. The incidence of sexual dysfunctions in chronic obstructive pulmonary disease (COPD) patients is largely unknown or may be perfunctorily attributed to the associated illness or to aging. This study investigated whether or not the impotence was related to the COPD itself as well as whether or not it nay stem from organic causes in a notable proportion of such patients. Methods : The sexual function was evaluated in 10 COPD patients and 10 normal control subjects. A nocturnal Rigi Scan was performed to evaluate the erectile function of each group. The level of hormones such as the free testosterone, prolactin and thyroid stimulating hormone (TSH) was measured, and a pulmonary function test and arterial blood gas analysis was performed. Results : The time duration and frequency of a penile erection were significantly lower in COPD patients than the controls (p<0.05). In addition, the $PaO_2$ levels correlated with the time duration of the penile erection. Conclusion : These results suggest that COPD is one of the causes of organic erectile dysfunction.

We measure a worker's analyzability by how correctly he grasps its causes when a problem occurs, comprehensiveness by how much he understand the overall process of his firm, and flexibility by how frequently unusual situations occur at his job. After controling firm-specific fixed of fandom effects, his age, tenure, position, and rank, the characteristics increase a worker's wage. A worker who grasps correctly the causes of problem is paid more by 5.2% than a worker who scarcely does. A worker who understands the overall process of his firm is paid more by 2.52% than a worker who understands roughly the process of his team or department. A worker whose job is mew one by one is paid more by 2.98% than a worker whose job is routine and repetitive.

In this paper, the factors of 1680 marine casualties occurred during 1986-1988 are analysed by the Principal Component Analysis. The main results are as follows: 1. Most of marine casualties result from the human factors such as careless operation and insufficient engine maintenance. Engine trouble is main part of accidents and great number of accidents is rated for fishing vessels. 2. Accidents are serious in case of cargo ships, passenger ships and tankers from the point of view of the damage of human life and properties. On the other hand, those are not so serious matter in case of fissing vessels and governmental vessels. 3. Grounding, collision and capsizal mainly result from careless operation, however material defect result in flooding

In this study, we investigated the cases where there were many opinions in the judgment of the cause of ignition in the case of 20 cases of frozen warehouse fire that occurred in 2017.The research methodology is the scientific fire survey method prescribed by the NFPA 921 CODE. Scientific fire investigation method is fire investigation method by logical reasoning through hypothesis setting, minimizing errors in judgment of ignition source. On the other hand, unscientific fire investigation methods cause many errors by the intervention of irrational factors such as subjective estimation, reasoning judgment, etc. This eventually leads to the problem of human and material responsibility and academic deterioration. In particular, fire not seen as compared to sighted fire makes more errors in ignition sources in the cause investigation. In this study, we set the hypothesis A and hypothesis B based on the review of the fire investigation report and the field survey on the fire case of the cold storage warehouse front line that occurred at ** city ** Mart in 2017.The set hypothesis was tested by the NFPA 921 code. This analytical method will be constructed by NEW Paradigm as a source of fire that is not seen in the future and a source of ignorant fire.In addition, the experimental data of this study will be used to inform the manufacturer and operator of the refrigeration warehouse and serve as basic data for fire prevention.
