The purpose of this study was to demonstrate the paths among the risk-protective factors that related to the resilience based on the Challenge Model. The subjects for this study were 209 children from divorced families in the 4th, 5th, and 6th grades of elementary schools in Seoul and Gyunggi-do. As the results, there were 28 paths which affected the resilience of children from divorced families based on the Challenge Model. The protective factors were easy temperament, problem-focused coping style, parental support, peer's support, higher socio-economic status, experiences in therapy, presence of siblings, contact with adult caretakers. The risk factors were higher grade, emotion-focused coping style, and children's gender, especially girls. This result demonstrated that each risk and protective factor not only affected resilience separately but interacted with one another.

Beaches have many risk factors that cause various accidents, such as drifting and drowning, these accidents have many risk factors. To analyze them, in this paper, we identify beach risk factors, and define the criteria and correlation for each risk factor. Then, we generate new risk factors based on Fuzzy theory, and define Situation Awareness for each time. Finally, we propose a beach risk assessment and prediction model based on linear regression using the calculated risk result and pre-defined risk factors. We use national public data of the Korea Meteorological Administration (KMA), and the Korea Hydrographic and Oceanographic Agency (KHOA). The results of the experiment showed the prediction accuracy of beach risk to be 0.90%, and the prediction accuracy of drifting and drowning accidents to be 0.89% and 0.86%, respectively. Also, through factor correlation analysis and risk factor assessment, the influence of each of the factors on beach risk can be confirmed. In conclusion, we confirmed that our proposed model can assess and predict beach risks.

Purpose: Operative morbidity and mortality from gastric cancer have decreased in recent years, but many studies have demonstrated that its prevalence is still high. Therefore, we investigated the risk factors for morbidity and mortality considering the type of complication in patients with gastric cancer. Materials and Methods: A total of 259 gastrectomies between 2004 and 2008 were retrospectively reviewed. Results: Overall morbidity and mortality rates were 26.6% and 1.9%, respectively. A major risk factor for morbidity was combined resection (especially more than two organs) (P=0.005). The risk factors for major complications in which a re-operation or intervention were required were type of gastrectomy, upper location of lesion, combined resection, and respiratory comorbidity (P=0.042, P=0.002, P=0.031). Mortality was associated with preexisting neurologic disease such as cerebral stroke (P=0.016). In the analysis of differen complication's risk factors, a wound complication was not associated with any risk factor, but combined resection was associated with bleeding (P=0.007). Combined resection was an independent risk factor for a major complication, surgical complication, and anastomotic leakage (P=0.01, P=0.003, P=0.011, respectively). Palliative resection was an independent risk factor for major complications and a previous surgery for malignant disease was significantly related to anastomosis site leakage (P=0.033, P=0.007, respectively). Conclusions: The risk factors for gastrectomy complications of gastric cancer were combined resection, palliative resection, and a previous surgery for a malignant disease. To decrease post-gastrectomy complications, we should make an effort to minimize the range of combined resection, if a palliative gastrectomy is needed for advanced gastric cancer.

For the prevention of marine accidents based on human factor, the risk assessment analysis procedure is proposed which consists of (1) the structural analysis of marine accident, (2) the estimation of incidence probability based on the Fault Tree analysis, (3) the prediction of ef-fectiveness to reduced the accident risk by suitable countermeasures in the specified functional system, and (4) the risk assessment by means of minimizing of the total cost expectation and the background risk. As a practical example, the risk assessment analysis for preventing is investigated using the proposed method.

The purpose of this study is to examine the prevalence of musculoskeletal disorders and ergonomic risk factors for workers of printing business. A self-reporting survey and task analysis using video camera were performed to identify ergonomic risk factors associated with musculoskeletal disorders. We used the OWAS, RULA, and REBA methods to quantify the risk factors, and the results show that the printing business have high risk of work-related musculoskeletal disorders.

Purpose: The study was designed to develop an instrument to measure risk factor-related deviant behavior (RFRDB) for the elderly. Methods: The preliminary instrument including 52 items to measure the risk factor-related deviant behavior for the elderly was developed through conceptual framework based literature review. The items were reviewed by experts to reveal the Content Validity Index (CVI). Then, construct validity and reliability were tested using factor analysis, comparative groups, and Cronbach's alpha with data from 233 elderly. Results: Among 52 items, 27 questions in the RFRDB instrument were selected from content validity and 21 questions in the final RFRDB were developed from testing validity and reliability. Results of empirical analysis(retest) of RFRDB were supported by 70% congruity with conceptual framework through literature review. The RFRDB has been completed by validity testing by known-group technique. The final developed RFRDB of the elderly has 21 questions each with a 4-point Likert Scale. Conclusion: The RFRDB may be utilized as a measurement to assess the risk of elderly deviant behavior.

Objectives: To identify the factors influencing the turnover intention of registered South Korean dental hygienists and analyze the effect sizes. Methods: Overall, 54 studies based on criteria of PICO from 1 January 2000 to 11 January 2022 were extracted. The factors related to turnover intention were applied to the ecological system theory and categorized. Subsequently, the effect size of the correlations was comprehensively meta-analyzed by dividing it into protective and risk factors depending on the negative or positive correlation direction. Results: For the overall effect size, the protective factor (ES_r=-0.458) was higher than the risk factor (ES_r=0.352). In the protective factors, organizational commitment and perceived organizational support belonging to the microsystem yielded the largest effect size. Furthermore, as for risk factors, burnout, job stress, work harassment, role conflict, and emotional labor belonging to the microsystem showed a moderate effect size. Conclusions: Factors belonging to the microsystem demonstrated a large effect size in both protection and risk factors for dental hygienists' turnover intention. Additionally, the factor showing the largest effect size was protective factor categorized into a microsystem.

본 연구는 국내 주식시장을 대상으로 고유변동성을 위험요인으로 산출한 CIV(common idiosyncratic volatility)요인이 가격결정요인으로 평가될 수 있는지를 검증하였다. 분석기간은 1992년 7월부터 2016년 6월까지로 설정하였으며, 총 288개월간의 월별 자료를 이용하였다. 본 연구의 주요 실증결과는 다음과 같다. CIV요인 계수를 기준으로 구성된 검증포트폴리오들의 CIV요인민감도 차이에 따라 통계적으로 유의한 수익률 차이를 보임으로써 CIV요인에 대한 위험프리미엄이 존재하는 것을 확인하였다. 또한, CIV요인에 대한 위험프리미엄은 기존의 요인모형들에 CIV요인을 추가함으로써 잘 설명되는 것으로 나타났다. 결과적으로 CIV요인은 유의한 위험프리미엄을 가지고 있으며 가격결정요인의 관점에서 평가가 가능한 것으로 판단된다.

Noise is a major cause of hearing loss in the air base. There are lots of risk factors of hearing loss including noise, and hearing loss can be accelerated by combined effects of these risk factors. Here in, we reviewed risk factors of hearing loss, and analysed key risk factors inducing hearing loss in the air base. Risk factors exacerbating hearing loss with noise were mainly investigated in this research because noise could not be an avoidable risk factor in the air base. Analysed data will contribute to make green environment minimizing hearing loss of pilots and supporting personnels in the air base.
