A mariner cadet gains the ability to identify and avoid potential collisions with other ships through ARPA/Radar simulation education. This research surveyed first domestic and overseas's rules (e.g., MOMAF's Standard, the STCW Convention, etc.) of the simulation education, upon investigation the only content and timing of this simulation-based education are specified according to these rules, and maritime education institutions issue the related certification autonomously after a student has taken the simulation because no simulation education module exists to further guide the ARPA/Radar simulation. As a result, it is difficult for students to acquire consistent maritime ability through ARPA/Radar simulation. This paper discusses standardization of these education modules to produce more consistent mariner ability, and verify the degree of improvement of education that would be achieved by enacting the proposed education module. The simulation education system used in maritime institutions in Korea was investigated, and scenarios reflecting traffic flow in actual waterways was proposed based on marine traffic surveys so teaching modules can educate/assess more effectively based on core marine abilities. Improvements in education and training were also verified using data collected over 2 years based on a standardized module. Each education institution can enact an effective, systematic education approach using standardized ARPA/Radar education modules proposed in this paper, and this can set a foundation to contribute to safer vessel navigation by improving maritime abilities.

The purpose of this study is to evaluate the different type of exercise training on the changes of blood variables and leptin in SD rats. For this study, SD rats were divided into three groups: control group (CG: n=10), swim trained group (SG: n=10), and treadmill trained group (TG: n=10). The animals were housed in a pathogen-free animal facility ($22-24^{\circ}C$, 50-60% relative humidity, 08:00-20:00 lighting hours) at D university animal center, Pusan, Korea). Food and water were available ad libitum. The trained rats underwent a 8-wk endurance swim training (5 times/wk) in water at $26-29^{\circ}C$ (SG) and treadmill training (5 times/wk) in DAEJONG treadmill for 60 min. All data were expressed as mean and standard deviation by using SPSS package program (ver 10.0). The result through the statistical analysis of this data were summarized as follows: 1. In the weight changes, there were significant differences among CG, SG and TG(p<.05) after regular swim and treadmill training. TG showed the lowest weight than the other groups. 2. In the epididymal & perirenal adipose tissue levels, there were significant differences among CG, SG and TG(p<.05) after regular swim and treadmill training. TG showed the lowest adipose tissue levels than the other groups. 3. In the triglyceride changes, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG showed the lowest triglyceride levels than the other groups. 4. In the insulin hormone, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG showed the lowest insulin levels than the other groups. 5. In the leptin changes, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG was the lowest than the other groups. Based on the results, Regular swim and treadmill training decrease body weight, epididymal & perirenal adipose tissue levels significantly, this is caused but by decreased triglycerides, insulin, and leptin hormone levels not by the other factors. Regular treadmill training decreased insulin hormone levels compare to swim training, however there was no direct insulin effect on the weight changes. and it might be the direct effect of leptin hormones.

본 연구는 공적개발원조 사업 중 하나로 개발도상국의 실무자 및 정책결정자의 물 관련 재해위험경감 역량 강화를 위한 교육 훈련 프로그램을 검토하고 개발하는데 목적이 있다. 특히, 물 관련 재해에 대한 구조적, 비구조적 대응방식을 균형있게 논의하고 지방정부 및 관련기관과의 협력, 지역사회기반의 재해경감정책 등 새로운 대응방식관련 교육 프로그램을 검토한다. 2000년-2006년 기간 Emergency Disasters Database (EM-DAT)에 기록된 전 세계 2,163건의 물 관련 재해는 총 29만 명 이상의 인명피해와 4,220억 달러의 재산피해를 초래하였다. 이런 재해는 개발도상국이나 선진국 모두에게 치명적이지만 특히 재해대응역량이 부족한 개발도상국에 막대한 손실을 초래하여 국가개발과 존망에 큰 위협이 되고 있다. 그럼에도 불구하고 대부분의 개발도상국은 재해관리를 간과하여 빈곤의 악순환에서 벗어나지 못하고 있는 실정이다. 본 연구는 2005년 효고행동강령(Hyogo Framework for Action: HFA)의 기본원칙, 2011년 중간평가 검토, 2015년 이후 제시될 새로운 재해위험경감 정책의 틀 속에서 재해위험경감 교육 프로그램을 연구하고자 한다. 이를 위하여 개발도상국 공무원을 대상으로 공적개발원조 프로그램을 운영한 천안의 중앙민방위방재교육원과 일본 고베시의 JICA 등을 방문하여 물 관련 재해 대응의 실질적 개선방향을 모색하였다. 물 관련 재해대응을 위한 교육 프로그램 대상은 실무자와 정책결정자로 설정하고 예방/대비/대응/복구의 유형에 따른 교육과정을 검토한다. 재해 대응 역량강화를 위하여 댐이나 제방 등 홍수위험관리기술과 같은 구조적 방식뿐만 아니라 근본적인 재해위험경감을 위한 홍수위험도 분석과 관리, 도시홍수위험경감계획, 관련 법규제정, 지역홍수위험경감과 민관협력 등과 같은 비구조적 방식에 대한 교육도 포함한다. 이런 측면에서 한국의 경제발전 경험과 물 관련 재해관리 경험을 정책, 사업, 사례와 연관시켜 교육을 진행하고 장단점 비교를 통하여 개발도상국 현지에 적합한 모델을 모색한다. 또한 재해발생시 피해규모를 최소화하게 하는 초동대응을 위해서 행정뿐만 아니라 지역, 시민, 기업 등 다양한 이해 당사자와 주체가 참여하는 종합대책교육을 포함한다. 사회경제발전의 지속을 위해서는 재해에 대한 관리가 매우 중요하다. 특히 인간의 삶에 너무도 익숙하지만 홍수, 가뭄 등으로 치명적인 피해를 야기하는 물 관련 재해에 대응하기 위해서는 물 관리와 관련 재해에 대한 전반적인 이해가 필수적이다. 따라서 한국의 물 관리 경험에 기초한 재해위험경감 교육과 훈련은 개발도상국의 효과적인 재해관리를 가능하게 할 것이다.

The main purpose of this study was to treat pica in a 2.8 year old child with severe mental retardation along with autistic tendencies. His developmental age ranged from 12 to 15 month on the DDST and he had no means of communication. He was on Tegretol 200mg for seizure control. His pica involved thumb sucking, putting toys into his mouth, and licking furniture wherever he went Besides pica, he had a rumination problem. The treatment strategies for his pica consisted of two phases : In phase 1, The child was taught toy play through a 3-step guided compliance training, while his pica and rumination behaviors were recorded to investigate whether active toy play could effect any change in the untreated pica and rumination behaviors of this child. In phase 2, a facial screening was used as a means to control his pica, while his rumination was recorded to see whether controlling his pica could bring any change in the untreated ruminating behavior. The results showed that the facial screening was very effective in decreasing his pica from an average of 18.6 times per 15 minute in the baseline to 2.3 times post-treatment. Response covariation was observed across pica and rumination while toy play compliance training alone was being conducted, and covariation across rumination was observed while pica alone was being treated with facial screening.

전 지구적으로 발생하고 있는 잦은 기상이변과 기후변화의 가속화로 자연재해 발생빈도 및 피해규모는 증가하는 추세로 나타나고 있다. 이러한 기상이변은 우리나라 또한 예외가 아니며 최근 한반도에서 발생한 적설로 인하여 많은 인명과 재산피해가 증가하고 있다. 본 연구에서는 기상청에서 제공하는 KMA-RCM 기후자료를 바탕으로 관측자료 및 시나리오의 온도, 강수, 적설량 간의 관계를 이용하여 기상청 산하 기상관측소 58개 대상 지점으로부터 목표기간별(목표 I:1979~2008년, 목표 II:2011~2040년, 목표 II:2041~2070년, 목표IV:2071~2100년) 적설량을 예측하였으며, 빈도별(20년, 30년, 50년, 80년, 100년, 200년) 확률적설량을 산정하고자 하였다. KMA-RCM 자료를 이용한 미래 적설량 예측은 기상인자들의 복잡한 비선형 조합으로 발생하기 때문에 적설량에 영향을 미치는 온도, 강수, 적설량의 비선형 과정들을 고려할 수 있는 신경망 모형을 이용하여 적설량 예측 모형을 구성하였고, 58개 대상 지점의 30년 이상 관측기상자료 중 온도, 강수, 적설량 자료를 이용하여 지점별로 훈련을 시켜 이를 기후변화 시나리오에 활용하였다. 확률적설량에서 매개변수 추정은 확률가중모멘트법(PWM)을 이용하였고 적정확률분포형으로는 시나리오적 방법 및 비시나리오적 방법에 대한 분포형 검정결과 가장 적합하다고 판정되는 Gumbel분포형을 선정하였다. 위의 방법론을 통하여 미래 목표기간별로 확률적설량을 확률적설량을 산정하였으며 본 연구결과는 기후변화 시나리오를 고려한 목표기간별 적설량 산정 및 관련 방재기준의 개선 방안 및 재설정 기준 마련에 기초자료로 활용될 수 있을 것으로 기대된다.

가뭄은 홍수와 달리 진행속도가 비교적 느리기 때문에 초기에 감지한다면 피해를 최소화 할 수 있다. 국내에서는 가뭄전망을 위해 물리적 기반의 기상-수문연계해석 시스템을 구축하여 월 내지 계절전망을 수행하고 있다. 물리적 기반의 가뭄전망은 수치예보모델의 불확실성을 가지고 있으므로 예보 정확도 개선의 측면에서는 통계적 모델을 같이 활용하는 것이 바람직하다. 최근 국외에서는 통계적 방법인 AI (Artificial Intelligence) 기술을 사용하여 가뭄을 전망하는 연구가 활발히 진행 중이나, 아직까지 국내에서는 관련연구가 미흡한 실정이다. 이에 본 연구에서는 ANFIS (Adaptive Neuro-Fuzzy Inference System) 기반의 댐 유입량 예측 모델을 구축하고 SRI (Standardized Runoff Index)를 활용하여 수문학적 가뭄전망을 수행하였다. 대상유역은 국내 주요 다목적댐이 위치한 충주댐 유역과 소양강댐 유역을 선정하였다. 수문 및 기상자료는 국토 교통부 및 기상청의 관측 댐 유입량, 관측 강수량, 관측 기온 및 장기기상예보 자료를 사용하였다. ANFIS 모델 구축을 위한 훈련 및 보정기간과 검정기간은 각각 1987~2010년과 2011~2016년을 선정하였다. 수문학적 가뭄전망은 지속기간 3개월의 1개월 전망 SRI3를 활용하였으며, SRI3는 관측유입량과 예측유입량을 결합하여 산정하였다. 댐 예측유입량 및 수문학적 가뭄전망의 정확도 평가를 위해 상관계수, 평균제곱근오차를 활용하였다. 댐 예측유입량 평가 결과 예측값과 관측값의 상관계수가 높게 나타났으며, 평균제곱근오차는 낮아 예측성이 뛰어났다. SRI3의 경우 관측값과 예측값의 가뭄발생시기가 유사하여 가뭄을 적절하게 반영하는 것으로 나타났다. 본 연구의 결과는 통계적 기반의 수문학적 가뭄전망기법을 개발하였다는 측면에서 의의가 있으며, 향후 물리적 기반의 가뭄전망정보와 결합한다면 보다 실효성이 향상될 것으로 기대된다.

This study addresses the issue of which factors make domestic works have turnover intention. To pursue this research issue, we utilized a public database "2017 Occupational Migration Path Survey", administerd by Korea Employment Information Service (KEIS). Decision tree method was applied to extract crucial factors influencing workers' turnover intention. They include 'the degree of matching the level of education with the level of work', 'the possibility of individual development', 'the job-related education and training', 'the promotion system', 'wage and income', 'social reputation for work' and 'the stability of employment'.
