The Hardy Kiwifruit (A. arguta (Sieb. & Zucc.) Planch. ex Miq.) is one of the valuable species due to their edible fruit, high content of nutritious substances, especially abundant of vitamin C, and distinctive flavor and medicinal usage. In order to develop a new A. arguta cultivar with larger fruit and high yielding, 168 candidate plants were collected from wild population in 12 locations distributed 4 provinces (Chungbuk, Gangwon, Gyeongnam, Jeonbuk) from 1985 to 1987. A clone bank that contained highly productive, superior genotypes of A. arguta was assembled in 1988, and 32 excellent clones were selected in 1996 through the clonal test for the growth and fruiting. Evaluation on these clones was done for the fruiting characteristics, yield trial, and major agronomic traits, such as Average Fruit Length (FL) and Width (FW), and Weight of Fruit (WF) and Individual Yields (IY), during 6 years (1997~2002). After the final selection, a new A. arguta cultivar, “Sae-Han” with larger fruit and high yielding was registered as a new variety denomination and certificated variety production and merchandising in 2006 (Table 1). “Sae-Han” is a tetraploid plant and has ellipsoid fruit shape, and has particularly large fruit size (Fig. 1, Table 3). The major agronomic traits of “Sae-Han” showed the large values and selection effect with an average of 43.6 mm (FL), 36.1 mm (FW), 29.4 g (WF), and 17.5 kg (IY), which are 35.0%, 19.9%, 81.5%, and 124.4% compared to the mean of 29 sample trees, respectively (Table 2).

A clone bank that contained highly productive and superior genotypes of R. coreanus Miq. was assembled in 1998. The clone bank was composed of a collection of 227 clones from 15 regions in Korea. From the clone bank, 198 clones that regularly completed flowering and fruiting were used as official materials for superior tree breeding. To evaluate the flowering and fruiting, the length of the fruiting lateral (LF), the number of flowers per fruiting lateral (NFL) and the number of fruit per fruiting lateral (NFFL) were investigated. Fruits were harvested when they fully ripen and the fruit length (FL), fruit width (FW), the weight of fruit (WF) and soluble solids were measured. In 2001, 17 of the original 227 clones were identified as being the most superior, and these selected genotypes were tested for regional adaptability in four different regions in 2002. Finally, these advanced selections including “Jung-Keum 1” were evaluated for flowering, fruiting and fruit production characteristics from 2002 to 2005. The new cultivar, “Jung-Keum 1” has dark red fruit color and larger fruit size than the contrast clone that was shown mean value for the most characteristics. Selection effect of the new cultivar were shown 130.8% (NFL), 128.3% (NFFL), 123.6% (WF) and 173.3% (yield/individual; YI) superior in comparison with the contrast clone, respectively.

석탄회의 시용은 토양의 pH를 증가시키는 경향을 보였으며, 무연탄회 보다는 유연탄회에서 그 효과가 더 현저하였다. 석탄회 시용에 의한 토양 pH 교정효과는 토양중 유효인산의 함량을 증대시켰으나 공시토양의 높은 pH와 고온, 건조한 환경으로 인하여 석탄회의 시용량이 증가하여 토양 중의 인산함량이 높을수록 식물체에 함유된 인산의 함량이 오히려 낮아지는 경향을 보였다. 토마토의 수량은 식물체내의 인산함량이 높은 처리구에서 많아 식물체 중의 인산 함량의 증가가 식물의 수량을 증가시키는 요인이 된 것으로 생각된다. 수확기별로 보면 모든 처리구에서 제 2과방의 주된 수확시기인 7월 21일에서 7월 30일 사이에 주당 수확된 과실의 수가 많았고, 과실의 개별 무게가 무거워 수량이 가장 많았다. 결론적으로 석탄회의 시용은 토양의 물리화학성을 개량시키는데 기여하는 것으로 생각된다.

This paper describes the current spatial patterns of the net primary productivity (NPP) of the terrestrial vegetation and carbon emission (C) in the world due to the burning of fossil fuels in order to clarify the amount of expansion of human activity. The C/NPP value varies spatially from almost zero to several tens of thousand times the local NPP. C/NPP is higher under the condition of extensive human activities due to a high human population density or when the local NPP is extremely low in severe climatic zones. In contrast, the low C/NPP areas are distributed mainly in sparsely populated districts, leading to a low impact of human activity. Although the area where C/NPP is less than 10% accounts for about 70% of the entire land area, one-third of these areas cannot contribute to carbon absorption because of low NPP with a shortage of climatic resources. Since more than half of the areas of the remaining areas are agricultural land and forest ecosystems with high NPP, the possible afforestation area was evaluated to be maximum of 30×106 km2; here only sequestrate carbons that correspond to 2% of the global total NPP are present. These analyses revealed that presently most of the areas where the NPP is high are those exclusively used by humans and that it is difficult for large-scale forest plantations to absorb a substantial amount of the carbon emitted annually by humans.

Shipping companies consider most of the ship turnaround time as a critical factor when selecting a rolling port for reducing costs. So, many researchers have been studying for the optimization of preplanning and high~performance of the Gantry Cranes (GCs) in container terminals for faster loading and unloading. Therefore, in this paper, we propose an RFID (Radio Frequency Identification) based RTLS (Real-Time Location System) for reducing the ship turnaround time in ubiquitous port environment. In addition, pre-planning based on ubiquitous computing environment will support the GC and Yard Tractors (YTs), and reduce ship turnaround time more effectively. Especially, the proposed method enormously enhances the productivity of loading for the twin-lift system It will reduce the whole lead-time in the process of port logistics.

This study was conducted to selected Korean black raspberry (Rubus coreanus Miq.) for high productivity. The eight major agronomic traits were investigated from 198 clones of the clone bank established in Korea Forest Research Institute, Suwon, Korea. The selection levels based on number of fruit per fructify lateral (NFFL) over 20, and fruit weight (FW) over 1.3g, and yield of individual per fructify lateral (YIFL) over 25g, were applied on 198 clones, resulted in 17 clones selected. The selected superior trees, 17 clones, appeared regional differences for amount of fruiting among 4 different test sites. When number of fruit per fruit petiole (NRFP), fruit weight (FW), yield of individual (YI) and sugar content were satisfied over 20, 1.4g, 6kg and 9.5 brix, respectively, as a select condition, 5 clones were reselected as the superior trees among 17 clones. for 3 years.

The productivity of container terminal is determined by its various operation methods. This paper aims at finding out the factors to enhance the productivity of container handling of quay crane, using simulation technique. Three levels of decision making in terminal operation, strategy, and tactics and operation are selected for defining parameters of simulation The result of the simulation and test shows that the significant factors to improve the productivity are the stack height of container, block dispersion and the distance in yard planning for shipment. Decision making in the operation level, however, is of significance in the mixed condition of strategic and tactical level. The result shows meaningful guidelines in decision making under strategic, tactical and operation level.
