The purpose of this study is to explore the mediator effect of the presidential candidate brand affiliated to the certain party toward enhancing the party brand equity and the presidential candidate brand value. In detail, firstly, the study attempts to identify the determinants of the party brand equity. Secondly, we clarify the factors of presidential candidate brand value. Finally, the paper testifies the proposed mediator model of the presidential candidate brand with respect to the impact of the belonging party brand equity in voting intention. Results show that the mediator effect of candidate brand exists between the affiliated party and the voting intention. In voting intention, the perceived quality of the party brand equity significantly influences on the candidate brand. Brand loyalty and Brand association of the party brand equity don't impact on the candidate brand significantly. In addition, the result proposes the all components of candidate brand value have significant impacts on voting intention. This paper is an initial attempts to regard the political parties and affiliated candidates in terms of brand marketing as the party brand equity and the candidate brand value respectively. With respect to better enhancing an approval rating, the study is proposed to the parties and candidates to-do list and direction of brand equity management.

Wide-area monitoring of tree-related high impedance fault (THIF) efficiently contributes to increase reliability of large-scaled network, since the failure to early location of them may results in critical lines tripping and consequently large blackouts. In the first place, this wide-area monitoring of THIF requires managing the placement of sensors across large power grid network according to THIF detection objective. For this purpose, current paper presents a framework in which sensors are distributed according to a predetermined risk map. The proposed risk map determines the possibility of THIF occurrence on every branch in a power network, based on electrical conductivity of trees and their positions to power lines which extracted from spectral data. The obtained possibility value can be considered as a weight coefficient assigned to each branch in sensor placement problem. The next step after sensors deployment is to on-line monitor based on moving data window. In this on-line process, the received data window is evaluated for obtaining a correlation between low frequency and high frequency components of signal. If obtained correlation follows a specified pattern, received signal is considered as a THIF. Thereafter, if several faulted section candidates are found by deployed sensors, the most likely location is chosen from the list of candidates based on predetermined THIF risk map.

The interaction between Agrobacterium and soybean has been studied at the transcriptome level but not at the metabolic level. However, it is necessary to investigate the difference in metabolites between susceptible and non-susceptible cultivars for high efficiency transformation. We investigated the difference in metabolites from sonicated soybean cotyledons of Korean cultivars and Bert cultivar. To identify difference in metabolites, sonicated extracts were analysed by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR/MS). The soybean cultivars were classified by susceptibility using green fluorescent protein expression. We found a difference in metabolites between the high susceptible and low susceptible cultivars. The FT-ICR/MS experimental m/z data of different metabolites were compared with theoretical m/z in KNApSAcK database. The candidate list was made using KNApSAcK and focused on phenolic compounds. These candidate metabolites are speculated to influence factors in the interaction. This list of candidates may be useful to investigate the interaction between Agrobacterium and plants to increase transformation efficiency.

Lung transplantation is considered a viable treatment option for patients with end-stage lung disease. Recent decades have seen a gradual increase in the number of lung transplantation patients worldwide, and in South Korea, the case number has increased at least 3-fold during the last decade. Furthermore, the waiting list time is becoming longer, and more elderly patients (>65 years) are undergoing lung transplantation; that is, the patients placed on the waiting list are older and sicker than in the past. Hence, proper management during the pre-transplantation period, as well as careful selection of candidates, is a key factor for transplant success and patient survival. Although referring and transplant centers should address many issues, the main areas of focus should be the timing of referral, nutrition, pulmonary rehabilitation, critical care (including mechanical ventilation and extracorporeal membrane oxygenation), psychological support, and the management of preexisting comorbid conditions (coronary artery disease, diabetes mellitus, gastroesophageal reflux disease, osteoporosis, malignancy, viral infections, and chronic infections). In this context, the present article reviews and summarizes the pre-transplantation management strategies for adult patients listed for lung transplantation.

한국어 형태소 분석은 일반적으로 입력된 문장의 분석 후보를 다수 생성한 후, 그 중 최적의 후보를 선택하는 과정을 거친다. 분석 후보를 많이 생성할수록 올바른 분석이 포함될 가능성이 높아지지만 동시에 모호성이 증가한다는 문제가 생긴다. 이를 해결하기 위해 본 논문은 단일 후보를 생성하는 규칙 기반 분석 모형을 제안한다. 분석 규칙은 품사 부착 말뭉치를 통해 자동으로 추출되기 때문에 규칙 구축비용을 필요로 하지 않을 뿐만 아니라 높은 분석성공률을 보인다. 분석이 성공한 경우에는 단 하나의 분석 후보만을 생성하기 때문에 최적 후보 선택 단계에서의 모호성이 효과적으로 감소되고, 계산 복잡도 역시 줄어든다. 규칙 모형으로 분석이 실패한 경우를 대비해 기존 확률 기반 모형을 결합함으로써 형태소 분석 성능을 향상시킬 수 있다.

The process of evaluating and selecting the best available techniques presents various characteristics for each country. In the case of EU, BAT is selected through TWG meeting after first screening, mass and energy balance, impact assessment and decision support process. Korea has proposed four principles to select BAT that can be carbon neutral for each environmental infrastructure in order to reduce greenhouse gas emissions. In order to evaluate and select the best available technique, it is necessary to differentiate the method according to whether it is a technique generally applied at the current workplace, whether it is a single technique or a combination technique, and whether it is a technology technique or management technique. In the case of a single technique, it should be evaluated whether it is a technique applied in the workplace, excessive cost, superior environmental technique over BAT, and secondary environmental pollution. In the case of multiple techniques, it is necessary to examine whether the emission standards are met and whether the pollutants can be treated at the same level as BAT. In the case of BAT candidates for management techniques, whether or not they contribute directly or indirectly to lowering the emission level of pollutants can be an important evaluation item. In the case of environmental techniques that are not generally applied in the workplace, it is recommended that the following 8 steps be carried out, including those prescribed by law. In the first stage, the list of performance evaluation factors is listed. In the second stage, the level of disposal of pollutants and the level of satisfaction with standards are listed. In the third stage, the environmental evaluation elements are listed. In the fourth stage, Is to list the economic evaluation elements, step 6 is to list the pollution and accident prevention evaluation factors, step 7 is the quantitative evaluation of the technical working group, and step 8 is BAT confirmation through deliberation of the central environmental policy committee.

The clipping value, defined as the log-likelihood ratio (LLR) in the case wherein all the list of candidates have the same binary value, is investigated, and an effective method to estimate it is presented for iterative tree search detection. The basic principle behind the method is that the clipping value of a channel bit is equal to the LLR of the maximum probability of correct decision of the bit to the corresponding probability of erroneous decision. In conjunction with multilevel bit mappings, the clipping value can be calculated with the parameters of the number of transmit antennas, $N_t$; number of bits per constellation point, $M_c$; and variance of the channel noise, $\sigma^2$, per real dimension in the Rayleigh fading channel. Analyses and simulations show that the bit error performance of the proposed method is better than that of the conventional fixed-value method.

Nephrotoxicity occurs when kidney-specific detoxification and excretion do not work properly due to the damage or destruction of kidney function by exogenous or endogenous toxicants. Exposure to drugs often results in toxicity in kidney which represents the major control system maintaining homeostasis of body and thus is especially susceptible to xenobiotics. Understanding the toxic mechanisms for nephrotoxicity provides useful information on the development of drugs with therapeutic benefits with reduced side effects. Mechanisms for drug-induced nephrotoxicity include changes in glomerular hemodynamics, tubular cell toxicity, inflammation, crystal nephropathy, rhabdomyolysis, and thrombotic microangiopathy. Biomarkers have been identified for the assessment of nephrotoxicity. The discovery and development of novel biomarkers that can diagnose kidney damage earlier and more accurately are needed for effective prevention of drug-induced nephrotoxicity. Although some of them fail to confer specificity and sensitivity, several promising candidates of biomarkers were recently proved for assessment of nephrotoxicity. In this review, we summarize mechanisms of drug-induced nephrotoxicity and present the list of drugs that cause nephrotoxicity and biomarkers that can be used for early assessment of nephrotoxicity.

For the last decades, molecular genetics has achieved great advances that the genes on the list of inherited muscle diseases are piling up. Those diseases of overlapping clinico-pathologic findings are now understood with discrete molecular pathogeneses. We are facing an exciting era that the long-waited gene therapy may eventually come true. Skipping of dystrophin exon 51 is on successful clinical trials, which will benefit about 13% of the children suffering from Duchenne muscular dystrophy. Exon skipping is under active investigation to expand the candidates. Hopefully it may cover majority of Duchenne muscular dystrophy mutations and some of other diseases. Adeno-associated virus is one of the most versatile tools for gene transfer. It may overcome the limitation of exon skipping. Here we review exon skipping technique of Duchenne muscular dystrophy and briefly discuss the other strategies being studied to cure inherited muscle diseases.
