Objective: This study aims to introduce the bridge resource management (BRM) training courses implemented in Korea and to analyze their effectiveness in several views. Background: BRM training will be a mandatory course for crew members of ships from 2017. At this stage, it is needed to check if the BRM training courses implemented until now was effective to the Korean maritime safety and to investigate if there are more effective training methods. Method: The effectiveness of BRM training intervention in Korea was compared with that of the other countries, using Kirkpatrick's (1976) training evaluation framework. Kim (2012)'s data on the BRM training effectiveness were re-analyzed in order to check if the effects of BRM training are dependent on the bridge work experience. Results: Many BRM training courses has been opened in Korea. However, the methods to assess BRM training effects used in Korea focused on the survey of subjective satisfaction level, not investigating trainees' attitude and behavior change. On the other hand, the effectiveness of BRM training was higher to the bridge officers with long work experience than with shorter work experience. Conclusion: The contents of BRM training should be changed to effectively apply to the context of the real-world exercise and be differentiated depending on the work experience. Research on the methods to measure the BRM training effectiveness is also more required. Application: The results of this study will aid to develop the BRM training courses for bridge officers of ships in the BRM training institutions.

Since the birth of animation, the United States has created many classic characters. For example, Mickey Mouse and Minnie, Tom and Jerry, Lion King, and Nemo, which are imaged with animal images, include Snow White, Bell, Mulan, and Aladdin. In addition, there are villain characters designed with strong personality and personality design, such as Snow White's stepmother Grimheel, Ursula, Bad Girl Crew El Radville, Scar, Captain Hook, and so on. These animation characters have been remembered for a long time with stories in people's minds, and have also brought laughter and emotion to people all over the world, which has brought a lot of business value to animation companies. Recently, the villain of American animation works is becoming more and more suited to the taste of the audience. The villain is not a symbolic image of the brutality we have seen before. They are not only visual images with rich and diverse personalities, but are also designed to suit the tastes of the public with a multifaceted inconsistency. They appear as ordinary people in our lives in works, or as powerful people who are not realistic. The villain characters designed in this way are real human miniatures appearing in the relationships in our lives, and they cannot judge good or bad only by their appearance. Through the study of villains in American animation, many villains in American animation were summed up, and villains could be classified into three types: brutal, violent, and sneaky. Based on this, it was possible to analyze the appearance and attire of the villain character in American animation, and to create a vivid and popular image of the villain, it was found that the character of the character should be emphasized when constructing the shape and costume of the villain character. In conclusion, the attractive formation of villain characters is an important part for successful animation. The production of vivid and long-lasting villain characters must begin with detailed settings such as personality, shape, and dress from the planning stage, which is not only the intention of the producer, but also a reflection of the aesthetic psychology that society should pay attention to today.

A number of perforated plates are utilized for the passage of the crew and the equipment, reducing weight and the arrangement of piping. Hull girders in double bottom and floor plates are the typical parts which have those plates in a ship structure, and the perforated plate is usually positioned at the place which has less loading without local strength problems. In the case of utilizing the plate inevitably at the place which has large strength, an opening of the plate has large effect on the buckling strength due to in-plane rigidity and ultimate strength. Therefore the assessments of the elastic buckling strength and the ultimate strength for the perforated plate are the essential requirements for determining the dimensions of the parts at the initial design stage. With above reason, a need of the reasonable assessments for the elastic buckling strength and the ultimate strength has evolved. The numerical series analysis with the consideration of the effect due to various aspect ratios and slenderness ratios were performed using finite element method in this research. Simple formulas for the design are also proposed from the above analysis.

This experiment was conducted with pot trial to evaluate effects of pretilachlor [2-chloro-2', 6'-diethyl-N(n-propoxythyl) acetanilide], pyrazoxyfen [ 1,3-dimethyl-4-(2,4-dichloro benzoyl)-5-phenacyloxy-pyrazole], pyrazolate (4-(2,4-dichloro benzoyl)-1,3-dimethyl-pyrazol-5-yl-p-toluenesulphonate] and their combinations on Echinochloa crew-galli. Herbicides were treated with different dosages under 3 cm water depth at 1st and 2nd leaf stages of E. crus-galli. E. crus-galli showed stunted symptom by treatment of pretilachlor and etiolation by treatment of pyrazoxyfen or pyrazolate after 4 days from treatment. Stunting and chlorosis degrees of E. crusgalli increased with high dosage of all herbicides at lst and 2nd leaf stage. Combination of pyrazoxyfen+pretilachlor (6+1.5)G or pyrazolate+pretilachlor (6+1.5)G showed positive synergistic effect of herbicidal action on E. crus-galli, therefore these combinations can control E. crux galli in paddy field with lower dosage than each single treatment of herbicides. Herbicidal effect of pyrazoxyfen on E. crus-galli was similar to pyrazolate in single treatment and combination with pretilachlor.
