In recently, thanks to the development of computer and internet, and reinforcement of digital media literacy of ordinary people, many users of comics and animations recombine contents into various ways, including UCCs. In a glance, it seems these outputs violates the copyrights of contents. But in reality, they helps the growth of the ecosystem of contents market, with increase of contents users. The reason of these reproductions inclines the characteristics of animation media. Animation, which are constituted by plastic symbols, auditory symbols, and narrative symbols, and Comic, which supports stories of Animations, affects as 'Imaginary signifier'. These signifiers helps users of contents to dismantle and reassemble stories. These aspects are seen in doujin culture, animation soundtrack fandom, and voice actor fandom. But In this article, we will concentrate into cosplay culture. Cosplay culture shows more active appearances than another fandoms. In especially, cosplay stage and daily cafe show more active reproductions of characters and communications. However, they are done by youth fans, which has not enough financial abilities: therefore, events are not sustainable and discontinued. And they have another limits, like lack of opportunity of performance. In the reality of Korean society, which needs of community making by community member, and hybrid culture, comics and animation productions in Korea are in need of access positively and encourage reproductions of active receivers of animations.

This paper aims to define Mecius's people-care theory(保民論), and aims to recognize the characteristics of social security contained in Mecius's people-care theory. Mecius considered to the public relief as King's obligation. So to speak, the King protects to the property of the people. Especially his people-care theory implicate to continuity of safety life, a relief fund on the property, protection of disaster damage. Continuity of safety life means to enabling the people procurable food, clothing and bury dead persons without difficulties. It's may be said that implicated to the theory and system of modern social-welfare. It is reason for his opinion that a state should construct in the minimum social safety network by taking responsibility for basis needs of life. He was a humanist so much. He thought about the pursuit of the human happiness and the improvement in quality of life. Therefore his idea nearly means to the social security system in a modern sense. His thought is not only an ideal background on the public assistance and a social relief security in the contemporary but also a relief activity system such as Jindaebup called historical prototype of social welfare. It is an important fact that his people-care theory implicate to social security system.

Recently, gusts, typhoon and tsunamis have been occurring more frequently around the world. In such an emergency situation, a moored vessel can be used to predict and analyze other vessel behavior, but if the mooring system is destroyed, marine casualties can occur. Therefore, it is necessary to determine quantitatively whether a vessel should be kept in the harbour or evacuate. In this study, moored ship safety in an exclusive wharf according to swell effects on motion and mooring load have been investigated using numerical simulations. The maximum tension exerted on mooring lines exceeded the Safety Working Load for intervals 12 and 15 seconds. The maximum bollard force also exceeded 35 tons (allowable force) in all evaluation cases. The surge motion criteria result for safe working conditions exceeded 3 meters more than the wave period 12 seconds with a wind speed of 25 knots. As a result, a risk rating matrix (risk category- very high risk, high risk and moderate risk) was developed with reference to major external forces such as wind force, wave height and wave periods to provide criteria for determining the control of capabilities of mooring systems to prevent accidents.

This study is for the inundation damage analysis caused by levee break, and for the applicability of GIS tool to make inundation map in the Jungrang stream basin which is one of the representative urbanized area in Korea. The FLDWAV was applied to the actual flood in 1998 to calibrate the parameters, and was used under the flood conditions of 100, 200 years and PMF for the analysis of inundation caused by the levee breach. As the conditions of the levee break, the duration of break(10, 30, 60 min), the width of break(10, 20, 30m) and the location of the break are considered. We found out that the range and the volume of the inundation are strongly influenced by the location of the levee break, the break width in order. And, we compared the two processes of making the inundation map using WMS and ArcView model. The Process 1 which use only WMS has the benefit by its simplicity but there could be considerable errors in making the inundation map, while Process 2 where the ArcView model is introduced to WMS has the capability of making detailed topography map but needs more process time. This study could contribute to levee breach flood analysis and making flood map to establish the EAP(Emergency Action Plan) in the urban basin.

The explosion of a chemical tanker ship during cargo transshipment via double-banking at Ulsan Port, resulted in major damage including fires involving nearby ships. As a follow-up measure to prevent the recurrence of similar accidents, the 'Safety Management of Dangerous Goods in Port' was established, and the designation of a transshipment pier for dangerous goods is required given the risk of explosion and the impact on major facilities in the port. This study evaluated the Fire & Explosion Index of major transshipment cargoes in Ulsan Port to design a transshipment pier based on the Explosion Risk Assessment. Based on the results of Fire & Explosion Index evaluation of styrene monomer and benzene, severe explosion risk was confirmed, and the exposure radius was calculated. Based on the results of the exposure radius, the risk range for each major pier was calculated, and 12 terminals were proposed as transshipment pier candidates considering port facilities, surrounding dangerous facilities, and residential aspects. Since the results of the study suggest transshipment piers based on the risk radius alone, maritime traffic safety, pier and mooring facilities, safety facilities and accessibility for emergency response should be considered comprehensively to designate actual transshipment piers.

최근 급격한 기후변화에 의한 이상가뭄 발생 등을 대비하기 위한 비상용수 또는 대체 수자원으로서의 지하수 개발수요가 증가함에 따라 기저유량 확보 및 수질개선 방안을 수립하는 것은 지속가능한 수자원 이용 관리 측면에 있어서 매우 중요하다. 국내 지하수 사용에 따른 하천유량의 변동에 관한 연구는 활발히 진행되었으나, 실질적으로 적용가능한 지하수 저감 방안 및 지하 수질개선방안에 대한 연구는 미비한 실정이다. 이에 본 연구에서는 바이오차를 이용하여 시험포를 설계 및 시공하였으며, 실내 인공강우 실험을 통해 지하 침투수 확보 능력 및 수질개선 효과를 평가하였다. 대조구는 폭 1 m × 길이 1 m × 깊이 0.60 m로 시공하였으며, 바이오차 시험포는 폭 1 m × 길이 1 m, 시험포 상단과 하단 각 0.10 m씩 대조구와 동일한 흙으로 채웠으며, 그 사이 0.40 m만큼은 바이오차를 채워서 시공하였다. 시험의 정밀도를 높이기 위해 동일한 조건으로 대조구와 바이오차 시험포 각 2개씩, 총 4개의 시험포를 시공하여 실내 인공강우 실험을 진행하였으며, 시험포에서 발생한 직접유출수와 기저유출수를 이용하여 바이오차의 지하 침투량 확보 및 수질개선효과를 분석하였다. 시험포 완공 후 총 2번의 실내인공강우 실험 결과 대조구에서 발생한 직접유출량은 총 0.214 m³, 바이오차 시험포에서는 총 0.194 m³로 대조구 대비 총 직접유출량 저감효과는 9.4%로 나타났다. 기저유출의 경우 바이오차 시험포(0.036 m³)에서 대조구(0.003 m³) 대비 약13배 많은 양의 기저유출수가 발생한 것으로 나타났다. 각 시험포에서 발생한 유출수의 오염부하를 산정해 대조구 시험포 대비 바이오차 시험포에서 발생한 직접유출수의 오염부하 저감효과를 분석한 결과 BOD₅ 항목과 COD_Mn 항목, 그리고 TOC 항목의 경우 26.3%과 22.0%, 그리고 27.6%로 저감 된 것으로 나타났으나, SS 항목과 T-N 항목, 그리고 T-P 항목의 경우 저감효과가 없는 것으로 나타났다. 이와 같이 바이오차는 지하 침투수 확보 능력은 효과적인 것으로 나타났으나, 직접유출수의 수질개선 효과는 미비한 것으로 나타났다. 그러나 바이오차의 지하 침투량 및 수질개선 효과는 바이오차 생산 시 사용된 열분해 방식, 사용된 바이오차의 양 등에 따라 편차가 클것으로 판단되며, 바이오차의 생산 방법, 토양 흡착 기간, 바이오차의 양 등 다양한 조건에서의 모니터링을 통해 정량화 되어야 할 것으로 판단된다.

Jinhae Bay, characterized by frequent runaway ships and strong winds during typhoon attacks, poses a high risk of maritime accidents such as ship collisions and groundings. This study aims to determine a safe separation distance between ships in the Jinhae Bay anchorage, considering the unique environmental characteristics of the Korean sea area. Analysis revealed that an average of 100-200 ships anchor in the typhoon avoidance area in Jinhae Bay during typhoon attacks, with approximately 70% of ships experiencing anchor dragging owing to strong external forces exceeding 25 m/s wind speeds. In this study, we analyzed and presented the separation distances between ships during anchoring operations based on domestic and international design standards, separation distances between ships used as actual typhoon shelters in Jinhae Bay, and appropriate safe distances for ships drifting under strong external forces. The analysis indicated that considering the minimum criteria based on the design standards and emergency response time, a minimum safe distance of approximately 400-900 m was required. In cases where ample space was available, the separation distance was recommended to be set between 700 to 900 m. The findings of this study are anticipated to contribute to the development of guidelines for establishing safe separation distances between ships seeking refuge from typhoons in Jinhae Bay in the future.

This study was conducted to investigate the purchasing status and to compare supplier performance evaluations between competitive bidding and negotiated contracts in school foodservice in Changwon, Korea. A total of 190 questionnaires were distributed and 167 (return rate 87.9%) were collected from June 29 to September 28, 2010, and then a total of 151 (analysis rate 79.5%) were used for the final analysis. First, 91.4% of food product purchases for school meals were contracted through competitive bidding, especially limited competitive bidding. It mainly consisted of agricultural products, processed food, and eco-friendly agricultural products (fruit). Second, 78.8% of schools purchased food products by negotiated contracts, while single negotiation accounted for 59.7%. Food products by negotiated contract consisted of meat, kimchi, and fish. Third, the purchase status of competitive bidding and negotiated contracts showed a significant difference in agricultural products (p<0.001), fish (p<0.001), meats (p<0.001), poultry (p<0.001), antibiotic-free poultry (p<0.001), eco-friendly grain (p<0.001), eco-friendly agricultural products (fruit) (p<0.001), eco-friendly processed food (p<0.001), processed products (p<0.001), milk (p<0.001) and general grain (p<0.001) except for kimchi. Fourth, comparative analysis of supplier performance evaluation (on a 5-point Likert scale) of school foodservice showed that price of product of competitive bidding (3.73) was significantly higher than that of negotiated contract (2.95) (p<0.001), and the overall performance level of the negotiated contract (3.85) was significantly higher than that of competitive bidding (3.61) (p<0.01). The supplier performance evaluation levels of product packaging (p<0.01), product quality at the time of delivery (p<0.001), hygiene of products (p<0.001), consistency to specification (p<0.001), swiftness of return and exchange (p<0.001), emergency delivery (p<0.001), service of delivery staff (p<0.05), and handling of complaints (p<0.001) of negotiated contracts were significantly higher than those of competitive bidding of school foodservice. In conclusion, school foodservice selected food suppliers both by adopting competitive bidding and negotiated contracts. And there was a significant difference of school foodservice supplier performance between competitive bidding and negotiated contracts in Changwon, Korea.

The preconditions of the usefulness of an operator safety training model in large plants are the versatility and accuracy of operational procedures, obtained by detailed analysis of the various types of risks associated with the operation, and the systematic representation of knowledge. In this study, we consider the artificial intelligence planning method for the generation of operation procedures; classify them into general actions, actions and technical terms of the operator; and take into account the sharing and reuse of knowledge, defining a knowledge expression ontology. In order to expand and extend the general operations of the operation, we apply a Hierarchical Task Network (HTN). Actual boiler plant case studies are classified according to operating conditions, states and operating objectives between the units, and general emergency shutdown procedures are created to confirm the applicability of the proposed method. These results based on systematic knowledge representation can be easily applied to general plant operation procedures and operator safety training scenarios and will be used for automatic generation of safety training scenarios.
