본 연구는 A4용지 규격의 종이 도안에 플랫포머 게임의 콘텐츠를 작성하고, 작성된 게임 콘텐츠를 모바일 기기의 카메라를 통해 인식하여 디지털로 변환하여 게임을 즐길 수 있는 시스템을 구현하였다. 종이도안을 활용한 게임 콘텐츠는 실제 종이에 필기구를 이용하여 직접 게임 오브젝트를 그려 넣는 방식을 사용한다. 오브젝트 디자인의 편의성을 높이기 위하여 핵심 게임 오브젝트의 패턴화하였고 의미가 있는 패턴들을 조합하여 새로운 조합 패턴의 생성할 수 있도록 하였다. 또한 한 장의 종이 위에 그릴 수 있는 게임 화면의 크기가 제한적인 점을 보완하기 위하여, 제작한 게임 화면을 조합하여 게임의 여러 스테이지를 구성할 수 있는 기능을 추가하였다. 종이 도안에 그려지는 게임의 오브젝트 이외의 게임 구성 요소들은 시스템 내부에서 추가할 수 있도록 하여 자유도 높은 콘텐츠 창작 제공하고 있다. 종이 도안을 통해 반복적으로 게임 콘텐츠를 제작하고 이를 디지털로 변환하는 과정을 보완하기 위하여 시스템 내부에서도 게임 콘텐츠를 제작하고 수정하는 것이 가능하도록 하였다. 본 연구에서 제안하는 서비스모델은 아동에게 다소 어려울 수 있는 게임창작 과정을 언플러그드 활동과 연동하여 손쉽게 디지털 게임 콘텐츠 창작의 경험을 제공하는 것이다. 이를 통해 아동을 대상으로 한 전통적인 방식의 언플러그드 활동을 디지털 활동과 연동하여 창작 활동에 대한 동기를 부여하고, 디지털 시대에 발맞춘 소프트웨어 리터러시를 함양할 수 있을 것이다.
본 연구는 게임 엔진을 통하여 게임개발 전 과정을 경험해 볼 수 있는 게임창작활동이 청소년의 소프트웨어 교육에 효과적인 수단임을 검증하고자 한다. 기존의 게임창작활동들은 프로그래밍을 위주로 게임개발 과정의 일부분만에 치우쳐 있거나 단순화된 교육용 프로그래밍 도구를 통한 일회성 체험에 그치는 경우가 많다. 게임 현업에서 사용되는 게임엔진을 기반으로 PBL(Project-Based Learning) 모형과 재구성 중심 모델을 적용한 소프트웨어 수업의 구성은 실제 게임창작 전반의 과정을 경험하도록 한다. 수업에 참여한 학생들은 스토리텔링, 그래픽 디자인, 프로그래밍 과정을 통해 게임을 제작하고, 제작한 게임을 출시하는 과정을 진행한다. 수업에 참여한 학생들을 대상으로 한 설문조사에서 소프트웨어에 대한 흥미와 이해도가 높아진 것을 확인하였다. 이러한 긍정적인 결과는 게임창작활동이 교육으로서의 가치가 있음을 나타낸다. 실제적인 게임창작활동의 경험은 발전된 형태의 융·복합적 소프트웨어 교육을 가능하게 할 것으로 기대한다.
The purpose of this study is to determine the effects of vibration on primary (e.g. plasma cortisol), secondary (e.g. plasma glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), Na+, K+ and Cl- and tertiary (e.g. mortality) stress responses in cultured eel, Anguilla japonica. For this purpose, three groups (including one control group and two stress groups) were set up. The control group was made exposed to vibration corresponding to 48 decibel (dB, V) (produced using electric vibrators) for 15 minutes per hour every day, and the two stress groups was made exposed to vibration corresponding to 58 and 68 dB (V) (produced using the same electric vibrators), equally, for 15 minutes per hour every day. Blood was sampled at day 0 (before starting vibration stress tests, BS), and days 1, 3, 5, 7, 9 and 11 (after starting vibration stress tests). As a result, plasma cortisol showed trend to continuously rise by consecutive stress from 4.1±0.1 ng/ml in BS. In 48 dB group (control), cortisol showed the highest level with 7.6±0.9 ng/ml after 7 days (p <0.05), but at 9 and 11 days was not significantly compared with BS level. In 58 dB group, the cortisol showed the highest level with 43.1±4.8 ng/ml after 1st day. Cortisol of 68 dB group increased significantly during the experimental period (14.4±2.3~32.0± 5.7 ng/ml) (p<0.05). In 58, and 68 dB groups during the experimental period differed significantly compared to 48 group (p <0.05). Glucose in 48 dB were increased from 42.0 ±5.7 (BS) to 52.5±2.1 (1 day), the level was not significantly from 1 to 11 days. Glucose in 58 and 68 dB groups was increased significantly than BS during experimental period (p <0.05). K+ in 68 dB increased significantly (p <0.05) from 2.3±0.2 mE/ql (BS) to 3.3± 0.5 mE/ql at 5 days. In 48 and 58 dB groups during the experimental period differed significantly (p <0.05). Na+ and Cl- levels were not differed significantly during the experimental period. AST and ALT in 58 and 68 dB groups showed trend to continuously rise by consecutive stress. At 7 and 9 days in AST, between 48, 58 and 68 dB groups differed significantly (p <0.05). In 48, 58 and 68 dB groups at 1 day, blood hematocrit increased significantly higher than BS. The 11 days after vibration stress, the mortality in 48, 58 and 68 dB groups was 1.1, 5.1 and 5.8%, respectively. The present results have shown that A. japonica exhibited ''typical'' physiological responses when exposed to chronic vibration stress. These data suggested that chronic vibration stress caused substantial stress in the fish; especially the persisting elevated plasma AST and ALT levels observed would be expected to adverse effect. In conclusion, chronic vibration stress could greatly affects the hematological characteristics in A. japonica.
For replacement of methyl bromide(MB) in Korea, there are several chemical options being introduced and developed in preplant and postharvest sections. In soil case, methyl-isothiocyanate(MITC) generating fumigant such as dazomet and metham sodium are currently being adapted for prevent from spreading soilborne disease and nematode, although there will be more successful application technology needed to develop in domestic circumstances. Also, ethanedinitrile(EDN), is newly developed chemical, could be one of the options to eradicate notorious soilborne diseases and nematodes near future. Ethyl formate(EF) now is showing the potential to replace MB in terms of consumer and worker safety and unwanted phytotoxic damage in routine MB fumigation. A phosphine gas(PH3) could be the last option to protect the import and export stored grains from stored grain insects and to solve the current issue such as PH3-resistant insect and consumer safety issues to replace metal phosphide. EDN also should be extended its use in not only timber and log fumigation in quarantine purpose but in use of national heritage and forest to keep wood infested pest safer. This presentation will be good opportunities to share the information and discuss with further research needs in current MB alterative program.
Fault plane solutions in North Korea and the northern part of the Yellow Sea (37.5˚N-40.5˚N, 124.5˚E-128.5˚E) was studied for the earthquakes that occurred from November, 2008 to May, 2013. The analysis was based on the data collected from seismic networks in Korea and China. Fault plane solutions were obtained from P and SH wave polarities and SH/P amplitude ratioes. Most earthquakes exhibited predominantly strike-slip fault characteristics with NNE-SSW or WNW-ESE nodal planes. The P-axes trends are mainly NE-SW or ENE-WSW direction in the northern part of the Yellow Sea and inland area of North Korea except some areas in the Hwanghae province. Fault plane solutions and main axis of stress field in the study region were similar to those observed in the southern part of the Korean Peninsula.
Government encourages small size learning circle activities as a part of ‘Learning Organizing Scheme’ to enhance the performances of the company through making SME employees develop themselves by giving them vision and hope who have poor working and learning conditions. Especially as the importance of learning circle (learning shift) activities is getting bigger, diversified studies on learning circles have been made. Accordingly, this study tried to verify the effects of activation of learning circle activities in SMEs on the quality performance of the organization and propose factors related to quality performance of the company.
