Objectives: This study aimed to examine risk-accepting personality traits and associated factors among farmers. Methods: Data were collected from farmers aged over 40 living in Goryeong, North Gyeongsang-do Province, Korea. Study participants were enrolled in the Korean Rural Cohort study from 2011 to 2014. Surveys for the risk perception of farming were made through face-to-face interviews. Chi-square tests and logistic regression analysis were conducted adjusting for gender, age, marital status, and education. Results: Several factors such as gender, age, marital status, age first worked as a farmer, duration of farming, and history of pesticide poisoning were associated with risk-accepting personality traits among farmers. Farmers with risk-accepting personalities tend to be older, less educated, and have self-employed health insurance. Farmers who started farming after the age of 50 are likely to be risk averse compared to farmers who started farming before the age of 20 (OR=0.41, 95% CI; 0.21, 0.82). Frequent spraying of pesticides was marginally associated with higher risk acceptance among female farmers (OR=1.61, 95% CI: 0.99, 2.64). Male farmers who had experienced pesticide poisoning in their lifetime showed higher odds of risk-accepting personality traits (OR=2.20, 95% CI: 1.03, 4.72) Conclusion: Risk-acceptors were more likely to spray pesticides frequently and to experience more pesticide poisoning compared to risk-averse individuals. This result suggests that farming hazards are to some degree driven by risk-accepting personality traits. Further investigation of how risk-accepting behaviors influence farming practices and pesticide poisoning is needed.

Purpose: The purpose of this study was a comprehensive understanding about maternal transition in mothers with high risk newborns according to the degree of situational meaning. Method: A methodological triangulation that combines qualitative and quantitative methods was used. The situational meaning of a high risk newborn mother was identified using a Family Meaning Attribution Scale. According to the degree of situational meaning, in-depth interviews were conducted at 3 time periods postpartum: between 3-10 days after childbirth, around the time of the newborn's discharge, and between 10-12 weeks after childbirth. Quantitative data was analyzed using descriptive statistics and t-test. Qualitative data was analyzed using Tutty, Rothery, & Grinnell's methodology. Result: The average score of the situational meaning in high the risk newborn mother was 53.57(possible score is between 0-96) and the average score of each item was 1.67. A Maternal transition process in the mother that has a positive situational meaning was conceptualized in three distinctive phases: confusion, accepting, and shaping phases. The Maternal transition process in the mother that has a negative situational meaning was also conceptualized in three distinctive phases: avoiding, conflicting, and accepting phases. Conclusion: It is necessary that the nurses provide high risk newborn mothers with individualized care considering both the situational meaning that is attributed to them and the maternal transition phase that they are faced with.

Risk Management does not mean accepting a risk but having a good grasp of, eliminating and controling the exact causes of known hazards. Good safety management plan or system for the safety of any systems need to include the procedures about standing safety goals, related technical information, time schedule, audit programs, etc at least. In this paper the summeries on general risk assessment techniques and the examples of risk assessment system and railway risk management strategies used in UK, Australia and Canada are introduced, and applicable establishment procedures for domestic railway industries are proposed.

Model verification and validation (V&V) is a current research topic to build computational models with high predictive capability by addressing the general concepts, processes and statistical techniques. The hypothesis test for validity check is one of the model validation techniques and gives a guideline to evaluate the validity of a computational model when limited experimental data only exist due to restricted test resources (e.g., time and budget). The hypothesis test for validity check mainly employ Type I error, the risk of rejecting the valid computational model, for the validity evaluation since quantification of Type II error is not feasible for model validation. However, Type II error, the risk of accepting invalid computational model, should be importantly considered for an engineered products having high risk on predicted results. This paper proposes a technique named as the response-adaptive experimental design to reduce Type II error by adaptively designing experimental conditions for the validation experiment. A tire tread block problem and a numerical example are employed to show the effectiveness of the response-adaptive experimental design for the validity evaluation.

Tabu search (TS) is a useful strategy that has been successfully applied to a number of complex combinatorial optimization problems. By guiding the search using flexible memory processes and accepting disimproved solutions at some iterations, TS helps alleviate the risk of being trapped at a local optimum. In this article, we propose TS-based heuristics for solving a class of clustering problems, and compare the relative performances of the TS-based heuristic and the simulated annealing (SA) algorithm. Computational experiments show that the TS-based heuristic with a long-term memory offers a higher possibility of finding a better solution, while the TS-based heuristic without a long-term memory performs better than the others in terms of the combined measure of solution quality and computing effort required.

As a result of accepting the '71 FUND Convention and enforcing the Oil Pollution Compensation Act 1992, we observed some benefits and costa. This paper analyses those benefits and costs and suggests se-veral key policy recommendations for the estasblishment of an effective oil pollution compensation regime in Korea. This paper identifies the said benefits and costs as follows : First, by establishing the oil pollu-tion compensation system as same as the international level, most of small and medium size of oil pollution damage which are caused by coastal tankers will be compensated by FUND. Second, most of oil pollution damage which are not covered by '69 CLC will be compensated by FUND. Third, some parts of FUND Contribution Fee and CRISTAL Contribution Fee to be charged by major oil companies will be doubled. However the limit of international oil pollution compensation system and the loophole outside the Oil Pol-lution Compensation Act 1992 suggest followings : 1) Radical risk management and insurance manage-ment of ocean going tanker owners, 2) Establishment of oil pollution claim settlement system, 3) Enforce-ment of crew and ship management for coastal tanker and 4) Establishment of Korean P & I Club.
