An interpolation-based unique decoding algorithm of Algebraic Geometry codes was recently introduced. The algorithm iteratively computes the sent message through a majority voting procedure using the Gr$\ddot{o}$bner bases of interpolation modules. We now combine the main idea of the Guruswami-Sudan list decoding with the algorithm, and thus obtain a hybrid unique decoding algorithm of plane AG codes, significantly improving the decoding speed.

In this paper we obtain a unique common fixed point theorem for four self-maps which are involved in (𝜙, 𝜓)-weak contraction of a partially ordered b-metric space. The necessary condition has been given to a space for the existence of an unique common fixed of the maps. And our work changed conditions and nonlinear contraction, and search for the unique common fixed point of the maps.

With such basic conceptions in mind. this study was aimed at reviewing the unique formative aesthetics of scarves for creation of modern apparel design. To this end, the drapeability of the rhythmically wrinkled fabric of scarf as well as its tying and enclosing representation were introduced into the apparel details and silhouette to create an apparel design flattering the moderns unique sense of aesthetics and emotion. In the same vein. threads were superimposed on the planar fabric to express a sense of volume and thereby, pursue a unique decorative effect of rich texture. Specifically. the objectives of this study are to highlight the practical use of scarf warming and its decorative formative aesthetics and thereby, apply it to apparel designs and develop an art fabric using the machine embroidery technique. and ultimately, suggest the possibility of unique but highly value-added apparel designs.

This paper considers a single facility scheduling problem for the fabrication of components supporting the subsequent assembly into products. Each product consists of two types of components, one is common to all products and the other is unique to itself. The unique components are processed individually and the common components are processed in batches, and a distinct setup is incurred for the production of a batch of common components. Under the so-called “batch availability” environment, we propose an efficient dynamic programming(DP) procedure for the optimal sequencing and batching schedule with minimum total completion times of products in the situation that each product is said to be complete if both common and unique components of the product are finished. Computational results show that the proposed DB procedure is more efficient than the previous work which has considered the same problem as this paper.

In the present study, we observed a unique association of the flat oyster, Ostrea denselamellosa obtained from a muddy substrate at Haechang Bay, the south coast of Korea in the spring of 2013. Fossilized or semi-fossilized veneriid clam shells, possibly Ruditapes philippinarum, were found adhering to the umbonal area of the flat oyster valves. This unique association of the flat oyster shells with the fossilized clam shells suggested that the flat oyster larvae utilized the clam shells as substrate during settlement. Since availability of clam shells in the muddy subtidal environment is limited, this unique substrata for the flat oyster larvae may limit recruitment of the flat oysters in the bay.

This study examines unique manifestations of intergenerational conflict related to the acculturation process of immigrant families. No scale that measured the acculturation aspect of intergenerational conflict exsited. Thus, a new scale was developed to investigate this unique aspect among Korean American adolescents. The study design was cross-sectional, and employed a convenience sampling method. The participants were Korean American adolescents of junior and senior high school age, 14 to18 years old. The study was conducted at eleven Korean churches and one hakwon (private out-of-school studies .institute) in Fairfax County, Virginia. Korean American adolescents expressed that the issues related to education, such as academic pressures and high expectations, caused intergenerational conflict most frequently. Unlike findings from previous studies, the participants indicated that language differences between parents and children rarely caused intergenerational conflict. Contrary to previous findings, none of the characteristics variables, such as age, gender, length of residency and language preference, were significantly correlated with this unique conflict. This study provides a rare opportunity to enhance our understanding on how Korean American adolescents interact with their immigrant parents.

For more complete process planning, machining sequence determination is critical to attain machining economics. Although many studies have been conducted in recent years, most of them suggests the non-unique machining sequences. When the tool approach directions(TAD) are considered fur a feature, both machining time and number of setups can be reduced. Then, the unique machining sequence can be extracted from alternate(non-unique) sequences by minimizing the idle time between operations within a sequence. This study develops an algorithm to generate the best machining sequence for composite prismatic features in a vertical milling operation. The algorithm contains five steps to produce an unique sequence: a precedence relation matrix(PRM) development, tool approach direction determination, machining time calculation, alternate machining sequence generation, and finally, best machining sequence generation with idle times. As a result, the study shows that the algorithm is effective for a given composite feature and can be applicable fur other prismatic parts.

Spin reticle infrared seekers have good linearity, and the pulse-modulated reticle seekers have good digital characteristics for anti-jamming processing. A basic design for a spin pulse-modulated reticle is introduced. This design uses the rotating design of the optical system in the spin infrared seekers and an improved design of the reticle in the pulse-modulated seekers. The reticle contains a unique well-designed slit to produce one pulse for each target in the spinning period. The target data will be carried by the unique pulse parameters. A simulation tool is implemented using the MATLAB packages for analyzing and evaluating the new design.

TAR(Transformation-Associated Recombination) cloning 법은 복잡한 고등생물의 게놈으로부터 유전자나 특정 염색체 부위를 선별적 분리를 가능하게 한다. 이 방법은 목적으로 하는 염색체 부위의 주변에 존재하는 비교적 짧은 게놈 염기서열에 대한 정보를 필요로 하며, spheroplast 형질전환 과정에서 게놈 DNA와 5'-와 3'-표적배열을 지닌 TAR vector 사이에서 일어나는 상동성 재조합과정에 의해 이루어진다. 본 연구에서는 single-copy 유전자의 클론닝에 필요한 specific hook의 최소 크기를 조사하였고, 서로 다른 TAR vector(radial과 unique vector)의 유용성을 조사하기 위해 동일한 single-copy 유전자의 클론닝을 통해 비교하였다. 그 결과, hHPRT 유전자에 대한 TAR cloning의 빈도는 hook의 길이가 750 bp∼63 bp의 범위에서 동일하게 나타났다. radial hook을 사용한 경우보다 unique hook을 사용하였을 경우 형질전환체의 수는 약 20배정도의 감소를 보였으나 목적으로 하는 재조합체의 분리 빈도는 두 배 이상 증가하였다. 그러므로 본 연구에서 two-unique TAR vector는 선별력이 높으므로 일반적 TAR cloning에 사용할 수 있으며, radial TAR vector의 경우는 병리학적 표본과 같이 제한된 게놈 DNA를 사용하는 경우에 더 적합하다고 볼 수 있다. 또한, single-copy 유전자의 분리에 필요로 하는 specific hoot의 최소 길이는 약 60 bp로도 가능하다는 것을 확인하였다.
