This study aimed at the effect on serum glucose and lipid profiles according to carbohydrate / lipid intake ratio in Korean 191 NIDDM patients. Most of NIDDM patients belong to under 50-64 years. As carbohydrate intake level increased, lipid intake level decreased. The group of higher carbohydrate / lipid intake ratio shows significantly high in fasting glucose level and postprandial glucose in NIDDM patients. The higher carbohydrate / lipid intake ratio the higher dietary linoleic and $\omega$-3 fatty acid level but not in dietary $\omega$3/$\omega$6 ratio. Serum HDL decrease inhigher carbohydrate lipid intake ratio group. Serum total lipid and PUFA level decrease according to ditary total lipid intake decrease in men but not significantly different.

The goal of this thesis is to support safety and reliability characteristics of software intensive critical systems. The verification method developed is innovative from current state of the art in what concerns the verification viewpoint adopted: focusing on software faults, and not, like many other approaches purely on fulfilling functional requirements. As a first step and based on a number of well defined criteria a comparison was made of available literature in the area of static non formal non probabilistic software fault removal techniques. But, None of the techniques evaluated fulfilled all criteria set in isolation. Therefore a new technique was developed based on a combination of two existing techniques: the FMEA and FTA. These two techniques complement each other very well. It is possible to integrate both techniques with commonly used techniques at system level. The resulting new technique can be shown to combine nearly all aspects of existing fault removal techniques.

저장 장치의 급속한 발전으로 인해 기존에 서비스할 수 없었던 개인 사용자를 위한 클라우드 서비스가 활성화되고 있다. 이 중 음악을 대상으로 하는 스트리밍 및 공유 서비스는 다양한 음악의 종류를 수용하기 위해 체계적인 분류를 필요로 한다. 기존의 분류체계는 단순히 작곡가나 업로더의 의견에 의해서 일방적으로 정해지기 때문에 사용자가 중심이 되는 클라우드 서비스에는 어울리지 않는다. 따라서 본 논문은 이와 같은 문제점을 해결하기 위해 사랑의 감정을 기준으로 새로운 분류체계를 제안한다. 자동적인 분류를 위해 데이터마이닝 기법을 접목시켰으며, 원활한 마이닝을 위해 오디오 음악 파일(raw data)을 정해진 크기로 자르고 feature extraction을 통해 오디오 음악 파일에 대한 전처리를 수행하였다. 이후 feature selection을 수행하기 위해 clustering을 이용해 유효한 중요도를 지나는 feature를 선별하였으며 선별된 feature를 토대로 SVN(Support Vector Machine)을 이용해 feature의 중요도에 대한 유효성을 검증함과 동시에 분류를 수행하여 감정을 기반으로 분류한 결과를 보였다.

In order to establish optimal double cropping system for getting the maximum annual productivity, we investigated annual fresh and dry yields of winter forage crops (WFC), Italian ryegrass (IRG) 'Kowinearly', triticale 'Joseong' and summer forage crop (SFC), 'Jonong' and 'Jowoo' as whole crop silage rice in the paddy field of Yeongseo of Gangwon Province. The double cropping of each crops was applied with 2 standard cultivation method of WFC and SFC from 2018 to 2020. For the WFC, the average percentage of dry matter (29.6%) of IRG 'Kowinearly' was lower than that (35.5%) of triticale 'Joseong'. The average fresh matter yield of IR G 'Kowinearly' was 2,662kg/10a that there was no significant difference from the 2,836kg/10a of triticale 'Joseong'. The average dry matter yield (996kg/10a) of triticale 'Joseong' was more than that (696kg/10a) of IRG 'Kowinearly'. For the summer forage crops, the average percentage of dry matter of whole crop silage rice, 'Jonong' was 34.5% that there was no significant difference from the 35.0% of 'Jowoo'. The average fresh matter yield (5,367kg/10a) of 'Jowoo' was more than that (3,966kg/10a) of 'Jonong'. And the average dry matter yield (1,936kg/10a) of 'Jowoo' was more than that (1,433kg/10a) of 'Jonong'. The total maximum dry matter yield was 2,982kg/10a with the combination of the WFC triticale, 'Joseong' and the SFC whole crop silage rice, 'Jowoo'. In conclusion, the combination of crops that can obtain the maximum yield of high quality forage for double cropping is sowing the WFC triticale, 'Joseong' in mid-October, harvesting 'Joseong' around the end of May and then SFC whole crop silage rice, 'Jowoo', to be transplanted in early June.

In this study, we evaluated the salinity tolerance of five forage rice cultivars (Mogwoo, Mogyang, Miwoo, Jowoo, and Yeongwoo) with respect to germination, seedling growth, productivity, and feed values in a reclaimed paddy field in Muan, Korea. We found that the cultivars Mogwoo, Miwoo, Jowoo, and Yeongwoo showed normal germination and seedling growth, even at saline concentrations of between 0.1% and 0.5%, whereas in contrast, there were significant reductions in the germination and seedling growth of Mokyang with an increase in salt concentration. Among the five cultivars assessed, the seedling growth of Mogwoo and Yeongwoo was relatively higher at different salt concentrations in hydroponic and sand cultivation. Furthermore, cultivation of the five cultivars in the reclaimed paddy field with an initial salt concentration of 0.3% revealed that Yeongwoo was relatively superior in terms of yield and feed value. In conclusion, the germination and early growth of Yeongwoo were relatively good at high salt concentrations, and the yield and forage value of this cultivar in a reclaimed paddy field were also relatively superior to those of the other assessed varieties.

This study presents a new method of estimating the size distribution of river bed gravel through image processing. The analysis was done in two steps; first the individual grain images were analyzed and then the grain particle segmentation of river-bed images were processed. In the first part of the analysis, the relationships (long axes, intermediate axes and projective areas) between grain features from images and those measured were compared. For this analysis, 240 gravel particles were collected at three river stations. All particles were measured with vernier calipers and weighed with scales. The measured data showed that river gravel had shape factors of 0.514~0.585. It was found that the weight of gravel had a stronger correlation with the projective areas than the long or intermediate axes. Using these results, we were able to establish an area-weight formula. In the second step, we calculated the projective areas of the river-bed gravels by detecting their edge lines using the ImageJ program. The projective areas of the gravels were converted to the grain-size distribution using the formula previously established. The proposed method was applied to 3 small- and medium- sized rivers in Korea. Comparisons of the analyzed size distributions with those measured showed that the proposed method could estimate the median diameter within a fair error range. However, the estimated distributions showed a slight deviation from the observed value, which is something that needs improvement in the future.

Cases of TBM tunnelling have been consistently increasing worldwide. In many recent subsea and urban tunnelling projects, TBM excavation has been preferably considered due to its advantages over drill and blast tunnelling. Difficult ground conditions are highly probable to appear in subsea and urban tunnels because of the shallow working depth and alluvial characteristics. Under the difficult ground conditions, ground reinforcement measures should be considered including grouting, while it is of great importance to select the optimal grout material and injection method to cope with the ground condition. The benefits from TBM excavation, such as fast excavation, increased safety, and reduced environmental impact, can be achieved by applying appropriate ground reinforcement with the minimum overrun of cost and time. In this report, various grouting methods were reviewed so that they can be applied in difficult ground conditions. In addition, domestic and international cases of successful ground reinforcement for difficult grounds were introduced for future reference.

This paper is concerned with a new paradigm for parallel evaluation of linear recursion rules which contain transitive dependency in a shared-nothing parallel architecture. For parallel evaluation of rules, we consider a shared-nothing parallel architecture that consists of a set of nodes and a message passing network to these nodes. An evaluation of normalized rules is a computation of the proof theoretic meaning of a collection of rules. We shall here define normalized recursion rules which contain transitive dependency, present an equivalent expression for the rule, propose a paradigm for Parallel evaluation of normalized rule based on the equivalent expression using join, partition, and transitive closure operations, and analyze response-time complexity.
