‘Jinhan’, a japonica rice variety, was developed from a cross between ‘Cheolwon68’ (IT218244) and ‘Junghwabyeo’ (IT260473) by the rice breeding team at National Institute of Crop Science in 2015. ‘Cheolwon68’ is early maturing and resistant to blast disease, and ‘Junghwabyeo’ is a cold-tolerant and high-quality variety. The growth duration of ‘Jinhan’ in the paddy field was 116 days in the Northern Central Highland in Korea, which was similar to that of ‘Jinbu’. The culm length of ‘Jinhan’ was 61 cm, which was 10 cm shorter than that of ‘Jinbu’. The panicle of ‘Jinhan’ was composed of 66 spikelets. The viviparous germination rate of ‘Jinhan’ was 33.2%. ‘Jinhan’ showed resistance to blast disease, but was susceptible to stripe virus, dwarf and black-streaked dwarf viruses, and plant hoppers. The milled rice grains of ‘Jinhan’ showed an excellent palatability index (0.23) and lower protein content (5.7%) than that of ‘Jinbu’. The grain milling characteristics of ‘Jinhan’ were similar to those of ‘Jinbu’. ‘Jinhan’ showed a milled rice productivity of 5.43 MT/ha at four sites cultivated in the Northern Central Highland(Registration No. 7318).

한국 수어는 소리로 말을 배울 수 없어서 사용하는 ‘보이는 언어’이고 한국수화언어를 줄인 말이다. 한국어나 영어와 같이 독립된 언어로 한국어와는 문법 체계가 다른 대한민국 농인의 고유한 언어이다. 하지만, 한국 사회에서는 수어를 일상어로 사용하는 농인이 수어만으로 다른 사람과 대화하거나 서비스 등을 이용하기에는 쉽지 않은 구조이다. 이에 본 논문에서는 택시라는 상황을 가정해 택시 안에서 학습된 모델이 농인의 수어를 인식하고 택시 기사에게 해당 의미를 전달하는 시스템을 제안한다. 제안 시스템을 통해 택시 기사는 농인(수어사용자)에게 응답할 수 있다. 본 논문에서는 한국수어 번역기 웹서비스를 설계 및 구현하여 실제 환경에서의 활용 가능성을 검증한다.

Statistical process cintrol is intended to assist operators of a stable system in monitoring whether a change has occurred in the process, and it uses several control charts as main tools. In design and use of control chart, it is rational that probability of false alarm is minimized in stable process and probability of detecting shifts is maximized in out-of-control. In this study, we establish bootstrap control limits for robust M-estimator chart by applying the bootstrap method, called resampling, which could not demand assumptions about pre-distribution when the process is skewed and/or the normality assumption is doubt. The results obtained in this study are summarized as follows:bootstrap M-estimator control chart is developed for applying bootstrap method to M-estimator chart, which is more robust to keep ARL when process contain contaminate quality characteristic.
