This study evaluated the ecological characteristics related to spike heading time of three Korean foxtail millet cultivars, i.e., one early and two late maturities, and a finger millet cultivar in the north-central region of the Korean Peninsula, Kangwon Province. The changes in heading time occurred due to the changes in planting time from mid-May to late June. The heading time of the early-maturity cultivars was early August, with 80 days required for heading (DH) for the mid-May planting; late August, with 65 DHs for the late June planting; and mid-late August, with 100 DHs and mid-October, with 65 DHs, respectively, for the late-maturity cultivars. The accumulated temperature at heading time ranged from 1,700℃ of mid-May planting to 1,500℃ of late June planting in the early-maturity cultivars. In contrast, it ranged from 2,100℃ to 1,900℃ in the late-maturity cultivars. The photoperiod at heading time ranged from 14.0 h to 13.2 h in the early-maturity cultivars, whereas it was from 13.2 h to 12.5 h in the late-maturity cultivars. Considering that the limiting heading time of Korean foxtail millet and finger millet in the northern region of Kangwon Povince is late August, the limiting accumulated temperature at the heading time was evaluated to be approximately 1,500℃ and 2,000℃ for early and late-maturity cultivars, respectively. The mean daily temperature from planting to heading time showed a negative correlation with the DH, which was shortened with the increase in mean daily temperature. This suggests that delaying the planting time from May to June in the north-central region of the Korean Peninsula increases the mean daily temperature during vegetative growth periods, resulting in the decrease of the DH and the accumulated temperature.

The purpose of this study is to find the meaning of subway station names. And through this, it is to find empirical evidence of “La Distinction” process of the people who live there. The detailed goal of achieving this objective is to analyze and categorize cases. Identify the subject of the process of establishing and revising subway station names to achieve detailed goals. In addition, it is divided into the exchange value and the use value of the name of the subway station. The content of this study first distinguishes the subject and content of changing the name of the subway station. The subject is divided into the subject of the process of enacting/amending the subway station name, and the content is divided into the exchange value and the use value of the station name. The subject was classified into cases where it was enacted/revised by local communities or civic groups and government-led organizations. The content was divided into cases where the reasons for enactment/revision focused on the use value of the subway station name and the case where the exchange value was focused. As a result of this study, it was confirmed that the enactment/revision of the station name changed from government-led to private-led. It was also confirmed that people's view of station names shifted from the use value to the exchange value. The reason for the move was the desire to increase assets and “La Distinction”. In the name of the subway station, capitalism called relocation could be confirmed as the exchange value of the value of use.

본 논문에서는 신경회로망을 이용한 양족 로봇에 대한 역모델 학습 제어에 관한 연구를 하였다. 5관절 양족 로봇 모델을 가지고 운동학과 동력학을 구했고 신경회로망의 학습으로 역모델을 구성하였다. 로봇 관절의 원하는 위치, 속도와 가속도를 신경회로망의 입력으로 하고, 원하는 토크를 출력으로 하여 토크 오차가 영(0)이 되도록 가중치를 학습시켜 조절하여 역모델을 구했다. 역모델에 의한 각 관절의 위치, 속도와 가속도를 제어하는 방법을 제안했다. 역전파 알고리즘을 사용하여 컴퓨터 시뮬레이션을 통해 역모델의 효율성을 입증했다. 반복횟수가 많을수록 SSE(sun square error)가 영에 가까워짐을 알 수 있었다. 또한 원하는 토크, 위치, 속도와 반복횟수에 따른 토크, 위치, 속도 오차의 차이를 표로 보여주었다. 반복횟수가 많을수록 토크, 위치, 속도 오차가 적음을 알 수 있었다. In this paper, learning control of inverse for biped robot using neural network is studied. Kinematics and dynamics of a 5-link biped robot model was attained, and by the neural network's learning capability a reverse model was made. Using the robots joint position, speed, and acceleration for the neural networks input and the desired torque as the output, adjusting neural network's learned weights to make the torque error to be zero and attained an inverse model. We proposed a method for each joint position, velocity and acceleration control by the inverse model, and the inverse model efficiency is proved by simulation using back-propagation algorithm. We now know that the larger the iteration number, the closer the SSE(sun square error) approaches to zero, and that the larger the iteration number, the smaller the error of torque, position, and velocity.

Sorghum seed is traditionally used as healthsupplements and the secondary food mixed with rice inKorea. While the research of reserve protein in sorghum seedhave been carried out in many countries used as major food,much less is known about reserve proteins of Korean localsorghum seeds. To obtain protein characteristics in 20 Koreanlocal sorghum seed, quantitative content of reserve proteinwas determined after fractionation by modified ‘Osbone’method and α-kafirin of prolamin was determined by SDSPAGE. Mean albumin, globulin, prolamin and glutelin contentsbased on total seed protein content of 20 Korean local sorghumseed were 6.2%, 0.9%, 57.9% and 35.1%, respectively. Sorghumcultivar with high prolamin were ‘Whin-susu’, ‘Whin-Chalsusu’,‘Whanggeum-Chalsusu’, and ‘Daepungshushu’. Sorghum cultivarwith high α-kafirin were ‘Whin-susu’, ‘Geumsan-Chalsusu’,‘Whin-Chalsusu’, and ‘Jangmok-susu’. Among the 20 varieties,‘Whin-susu’ and ‘Whin-Chalsusu’ were selected as high α-kafirin and prolamin sorghum cultivar, which showed 64.5and 71.9% of prolamin contents, respectively

Sorghum seed is traditionally used as secondaryfood sources in addition to rice in Korea. While the hypoglycemiaregulating phytochemicals have been found insorghum seed, peptides related with hypoglycemia never beenstudied before. To obtain the peptide characteristics and thespecifically high-expressed peptides in hypoglycemic sorghumseed, peptide profiles of seven hypoglycemic and five nonhypoglycemicsorghum lines bred in RDA were determinedusing surface-enhanced laser desorption/ionization time-offlightmass spectrometry (SELDI-TOF MS). The twelve sorghumlines exhibited 104 peptides on CM10 protein chip array(weak cation exchange) and 95 peptides on Q10 (weak cationexchange) in the molecular mass range from 2,000 to 20,000Da. Heat map via supervised hierarchical clustering of thesignificantly different peptides (p < 0.01) in peak intensityamong the 12 lines effectively revealed the specifically upregulatedpeptides in each line and distinguished between7 hypoglycemic and 5 non-hypoglycemic lines. Throughthe comparison with hypoglycemic and non-hypoglycemiclines, 10 peptides including 2231.6, 2845.4, 2907.9, 3063.5,3132.6, 3520.8, 4078.8, 5066.2, 5296.5, 5375.5 Da werespecifically high-expressed in hypoglycemic lines at p <0.00001. This study characterized seed peptides of 12 sorghumsand found ten peptides highly expressed for hypoglycemicsorghum lines, which could be used as peptide biomarkersfor identification of hypoglycemic sorghum.

Background: Activation of renin-angiotensin system (RAS) has been an important mechanism of microvascular and macrovascular complications in diabetic patients. It has been reported that RAS blockades reduce the development and progression of diabetic nephropathy. The aim of this study was to evaluate whether valsartan, an angiotensin II receptor blocker (ARB), reduced blood pressure and urinary albumin excretion rate (UAER) in hypertensive type 2 diabetic patients. Method: Three hundred forty-seven hypertensive type 2 diabetic patients who had not taken angiotensin converting enzyme inhibitors or ARB for 6 months prior to this study were enrolled. We measured blood pressure and UAER before and after 24 weeks of valsartan treatment. Result: Baseline mean systolic and diastolic blood pressure was 143 ± 15 and 87 ± 11 mmHg, respectively and the median albumin excretion rate was 27 ug/mg. Reduction in systolic and diastolic blood pressure was 16 mmHg/10 mmHg and the median UAER was 19.3 ug/mg after 24 weeks (P < 0.01, respectively). When we divided the subjects into three groups according to the UAER (normoalbuminuria, microalbuminuria and macroalbuminuria), significant changes were reported in the microalbuminuria and the macroalbuminuria groups. Thirty-eight (42%) patients with microalbuminuria improved to normoalbuminuria and twelve (41%) patients with macroalbuminuria improved to microalbuminuria. We found an association between the improvement of blood pressure and UAER (R = 0.165, P = 0.015). Conclusion: We concluded that valsartan reduces urinary albumin excretion and blood pressure in hypertensive type 2 diabetic patients.
