In order to develop a new variety of rice that adapts to the climate of Aomori prefecture and possesses characteristics suitable for production of high quality Japanese sake, artificial cross experiments were executed between Yamadanishiki, which is widely used nationwide as an authentic variety of rice for sake production, and Hanafubuki, which was peviously developed by Aomori prefecture. An excellent hybrid, named Hanaomoi, was selected and fixed by a series of selection experiments and systematic cultivation. Unpolished Hanaomoi rice contained less amount of protein than Yamadanishiki and Hanafubuki. Unpolished rice of Hanaomoi was harder than Yamadanishiri and Hanafubuki, therefore polishing treatment was done in high yield and one could obtain a high degree of polish on the rice(namely 40% polishing). These features are advantageous to production of high quality of sake.Test brewing using 40% polished Hanaomoi gave rise to a characteristic sake that contained a slightly higher amount of alcohol and flavor components than Yamadanishiki and Hanafubuki. Sensory tests concluded that sake from Hanaomoi was as superior as the one from authentic Yamadanishiki. Hanaomoi is a promising variety of rice suitable for production of a high quality sake exclusive to Aomori prefecture.

In this paper we provide characterizations for the Gromov hyperbolicity of some particular Denjoy domains and besides some sufficient conditions to guarantee or discard the hyperbolicity of some others. The conditions obtained involve just the lengths of some special simple closed geodesics in the domain. These results, on the one hand, show the extraordinary complexity of determining the hyperbolicity of a domain and, on the other hand, allow us to construct easily a large variety of both hyperbolic and non-hyperbolic domains.

For the purpose of breeding a high-yield superior variety of Korean raisin tree (Hovenia dulcis var. koreana Nakai), whose value as an edible and medicinal resource is increasing, tree candidates for superior individuals were selected from its 11 habitats in Korea from 1996 to 1998. A clone bank preserve was created in 1998 with 70 clones proliferated by grafting; the fruition traits (e.g., the number of fructified laterals, the average number of bunches per fructified lateral, the average number of bunches per fruiting lateral, the fruitpetiole weight per individual, and the yield per individual) of 47 clones that had bloomed and borne fruit were investigated and analyzed in 2002; five upper-ranking clones whose yield per individual exhibited a 261% improvement against the total average were picked in 2005; and three clones, including 'Poong-Sung 1', that showed a difference in their fruit petiole ripening stage, were finally selected in 2007 as high-yield new cultivars of Korean raisin tree.

Renal nutcracker syndrome (NCS) is the entrapment of the left renal vein between the abdominal aorta and superior mesenteric artery. Although uncommon in pediatric patients, early diagnosis is crucial to avoid potential severe complications, such as anemia or renal vein thrombosis. NCS presents a variety of symptoms, most commonly including "Triade's symptoms"-hematuria, proteinuria, and flank pain. Diagnosis and treatment include invasive and noninvasive management, although due to a lack of pediatric clinical studies, management is widely variable. Conservative diagnosis and treatment are recommended as a first-line option for pediatric patients; however, invasive surgical treatment may be recommended based on symptom severity. This review aims to provide a comprehensive overview of NCS in children to better understand the widely variable incidence, occurrence, and management from early on to allow for early-onset management.

Irreparable massive rotator cuff tears can significantly impact daily life; and these types of tears can be difficult to repair completely, especially in younger patients who are more active and have higher functional requirements. Since its introduction by Mihata and the colleagues, superior capsular reconstruction (SCR) has gained popularity in the treatment of irreparable massive rotator cuff tears and has shown promising short-term results. A variety of studies have focused on the clinical and biomechanical outcomes of this procedure. This article reviews the biomechanics, indications for the surgical procedure, graft options, surgical technique, and rehabilitation from SCR.

Utilization of the various cocoon beds were evaluated by raising the silkworm variety "Seul-ak${\times}$Soyang"according to cocoon quality produced in spring of 1969: Rotary cocoon bed, improved cocoon bed, grima cocoon bed, wood framed straw rope cocoon bed, and pine cocoon bed. In addition the economical analysis was made on the basis of cocoon price in spring of 1976. 1. The Rotary cocoon bed has economically much advantages in many ways; easy cocoon collection and percentage of best cocoon, percentage of cocoon shell, reelability and percentage of raw silk. It may give 8100 won for an extra income per box and increase by raising higher yielding variety. 2. The grima cocoon bed is superior to the wood framed straw rope cocoon bed, and the pine cocoon bed and it is comparatively easy set-up even though it is inferior to the improved cocoon bed in many characters.

Ranging from a variety that a consumer to purchase and consume, and a variety with high quality and pest resistance, sustaining biological diversity as well as hiring global experts who understand breeding policy, it tightly maintains relationship with producer, consumer, and exporter to promote superior species for customized export to exporting country. By carrying out researches on cost saving and how to shorten the period of apple to cultivate, it consolidates its stance as a competent apple exporting country of apple and pear with high competetiveness. In order to compete against apple and pear of New Zealand, farmers argue that they need budget and researchers also argue that "No money, no research." Due to certain limit of governmental budget support, it is believed that it is time to fund our own way to promote apple research center. To come up with the best apple production, all of those who associates with apple such as farmers, researchers, government, exporters, and consumer should do their best to enhance the apple and pear industry.

In this paper, we present a novel digital watermarking technique based on the concept of multiresolution decomposition and Human Visual System(HVS). Proposed watermarking is to embed watermark by quantization, that is to construct ‘perceptually lossless’quantization matrix, by using a quantization factor for each level and orientation and variance within a band. We compare our approach with another wavelet domain watermarking methods. Simulation results show the superior performance of robustness for variety image distortions.

In this paper, we propose a human face detection algorithm using adaptive skin color model and neural networks. To attain robustness in the changes of illumination and variability of human skin color, we perform a color segmentation of input image by thresholding adaptively in modified hue-saturation color space (TSV). In order to distinguish faces from other segmented objects, we calculate invariant moments for each face candidate and use the multilayer perceptron neural network of backpropagation algorithm. The simulation results show superior performance for a variety of poses and relatively complex backgrounds, when compared to other existing algorithm.

전국에서 수집된 오차드그라스 재래종들 중 생육특성 및 내재해성이 우수한 계통을 선발하여 육성된 4계통을 집단 교배(polycross)하여 생산된 합성계통을 '합성35호'라 하고 이를 2008년 천안에서 생산력 검정시험을 수행하였다. 2012년부터 2014년까지 3년 동안 천안, 횡성, 진주 및 제주 등 4 지역에서 지역적응성 검정을 실시하여 생육특성 및 수량성을 조사하였다. 2014년 직무육성 신품종 선정심의회에서 생육특성과 수량성이 우수한 '합성 35호'를 신품종 '럭키원'으로 명명하였다. '럭키원'의 주요 특성을 요약하면 다음과 같다. '럭키원'의 생육형태는 중간형이며, 잎은 담녹색이고, 출수기에 지엽 길이는 표준품종인 암바 보다 짧으며, 상부 절간장은 길고 풍엽성이 양호하였다. '럭키원'은 암바에 비해 출수기는 5월 11일로 표준품종인 암바 보다 2일이 늦으며, 출수기의 초장은 87 cm로 3 cm 길었다. 내습성과 내병성은 '럭키원'이 암바에 비하여 비교적 강하였으며, 녹병은 럭키원이 암바 보다 약간 강한 편이었다. '럭키원'의 ha당 건물수량은 16,191 kg으로 암바 보다 38% 많았으며, 특히 횡성지역에서 증수하였다. '럭키원'의 건물 소화율은 암바에 비해 높았으며 조단백질 함량은 11.3%로 약간 높았다.
