"안동국제탈춤페스티벌2011"을 대상으로 축제참가자의 지역축제 의의에 대한 인식과 평가에 관해 연구 하였다. 연구결과는 먼저, 안동국제탈춤페스티벌에 참가한 축제참가자들의 인구학적 특성은 대졸학력의 20~40대 연령층과 가족단위의 방문객이 주를 이루었으며, 외지인과 지역주민 간의 인구학적 특성의 차이는 거의 나타나지 않았다. 둘째, 지역축제 특성에 대한 인식을 알아보기 위해 실시한 설문조사 결과, 지역축제가 지역문화자원 활용정도와 지역축제의 주제 반영정도에 대하여 두 집단 모두 긍정적으로 응답하였다. 주제의 반영정도는 지역주민들의 사례축제에 대한 긍정적인 인식이 보다 높은 것으로 나타났다. 셋째, 지역축제의 의의는 지역주민 화합, 지역 경제활성화 그리고 지역 홍보 및 지역 이미지 제고이다. 여기서 지역주민과 외지인들은 지역 홍보 및 이미지 제고를 가장 긍정적으로 인식한데 비해 지역주민 화합에는 다른 설문항목에 비하여 긍정적인 인식이 낮았다. 따라서, 사례축제가 보다 지역사회에 깊게 뿌리내림 하기 위해서는 축제를 통한 지역주민들의 문화적인 삶의 질을 향상시키고 주민들의 적극적인 참여를 보다 유도할 필요성이 있다. 그에 대한 개선방안으로 지역주민들을 위한 프로그램마련과 축제의 기획, 집행, 평가 과정에서 지역주민들의 참여가 가능한 다양한 창구를 마련하여 지역주민들의 참여를 확대할 것을 제시한다.

Background: The role of clinical pharmacists in medication therapy to improve clinical and economic outcomes has been reported in the literature. This study was conducted to analyze the changes in details of medication interventions before and after the introduction of clinical pharmacists into the care of neurocritical care unit (NCU) patients, and to evaluate the economic effects of clinical pharmacists by calculating the avoidance cost. Methods: A retrospective study was conducted reviewing the electronic medical records from June 2013 to May 2014 (before), and from June 2016 to May 2017 (after). We calculated the number and rates of intervention, the acceptance rates of it, and also reviewed the list of interventions. We calculated avoidance cost if there was no intervention. Results: The monthly mean number of interventions increased from 8.0 (${\pm}5.7$) to 31.7 (${\pm}12.8$) (P<0.001) and the frequency of intervention also increased from 0.8% to 1.6% (P=0.003). The most frequently provided pharmacist intervention was nutritional support before introduction of clinical pharmacists and discussions on the medication plan after. The number of classified interventions was 14 before introduction of clinical pharmacist services and 33 after. The calculated cost avoidance associated with a clinical pharmacists' integration was 77,990,615 won per year. Conclusion: Introduction of clinicals pharmacist into the NCU was associated with increased intervention rates and expanded types of clinical interventions. The cost avoidance achieved by the pharmacists' interventions can be further explored to evaluate if similar expansions of pharmacists' services achieve similar results in other settings.

In this paper, we propose a scheme for partially dynamic lane control for energy saving in multilane-based high-speed Ethernet. In this scheme, among the given transmission lanes, at least one lane is always operating, and the remaining lanes are dynamically activated to alleviate the network performance in terms of queuing delay and packet loss in the range of acceptance. The number of active lanes is determined by the decision algorithm based on the information regarding traffic and queue status. The reconciliation sublayer adjusts the transmission lane with the updated number of lanes received from the algorithm, which guarantees no processing delay in the media access control layer, no overhead, and minimal delay of the exchanging control frames. The proposed scheme is simulated in terms of queuing delay, packet loss rate, lane changes, and energy saving using an OPNET simulator. Our results indicate that energy savings of around 55% (or, when the offered load is less than 0.25, a significant additional savings of up to 75%) can be obtained with a queuing delay of less than 1 ms, a packet loss of less than $10^{-4}$, and a control packet exchange time of less than $0.5{\mu}s$ in random traffic.

Increasing numbers of value added chemicals are being produced using microbial fermentation strategies. Computational modeling and simulation of microbial metabolism is rapidly becoming an enabling technology that is driving a new paradigm to accelerate the bioprocess development cycle. In particular, constraint-based modeling and the development of genome-scale models of industrial microbes are finding increasing utility across many phases of the bioprocess development workflow. Herein, we review and discuss the requirements and trends in the industrial application of this technology as we build toward integrated computational/experimental platforms for bioprocess engineering. Specifically we cover the following topics: (1) genome-scale models as genetically and biochemically consistent representations of metabolic networks; (2) the ability of these models to predict, assess, and interpret metabolic physiology and flux states of metabolism; (3) the model-guided integrative analysis of high throughput 'omics' data; (4) the reconciliation and analysis of on- and off-line fermentation data as well as flux tracing data; (5) model-aided strain design strategies and the integration of calculated biotransformation routes; and (6) control and optimization of the fermentation processes. Collectively, constraint-based modeling strategies are impacting the iterative characterization of metabolic flux states throughout the bioprocess development cycle, while also driving metabolic engineering strategies and fermentation optimization.

The purpose of this study is to compare the living cultures among three types of undergraduate students, grouped by commuting patterns, attending universities in Chung-Cheong Do: a long-distance type, a short-distance type, and a living-alone type. The survey was performed with questionnaires and the subjects were 1167 undergraduate students. The results are as follows: for a long-distance type, the levels of housing environments and consumption expenditures were relatively high, but the students felt constrainted by the commuting time. For a short-distance type, the consensus in decision-making with parents and the degree of conflict reconciliation were the lowest. For a living-alone type, the levels of housing environments and consumption expenditures were relatively poorer, but the students spent relative]y more time at school and the attitudes of school and department which they belong to were relatively higher.

Accurate finite element (FE) models are needed in many applications of Civil Engineering such as health monitoring, damage detection, structural control, structural evaluation and assessment. Model accuracy depends on both the model structure (the form of the equations) and the model parameters (the coefficients of the equations), and can be generally improved through that process of experimental reconciliation known as model updating. However, modelling errors, including (i) errors in the model structure and (ii) errors in parameters excluded from adjustment, may bias the solution, leading to an updated model which replicates measurements but lacks physical meaning. In this paper, an application of ambient-vibration-based model updating to a large-scale benchmark prototype of a building structure is reported in which both types of error are met. The error in the model structure, originating from unmodelled secondary structural elements unexpectedly working as resonant appendages, is faced through a reduction of the experimental modal model. The error in the model parameters, due to the inevitable constraints imposed on parameters to avoid ill-conditioning and under-determinacy, is faced through a multi-model parameterization approach consisting in the generation and solution of a multitude of models, each characterized by a different set of updating parameters. Results show that modelling errors may significantly impair updating even in the case of seemingly simple systems and that multi-model reasoning, supported by physical insight, may effectively improve the accuracy and robustness of calibration.

역사적으로 권력과 기록물의 관계는 불가분의 관계이다. 기록물은 권력행위의 기록된 흔적이며 권력의 의지는 기록물의 존재에 상당한 영향을 미친다. 민주주의 사회에서 권력은 자신의 행위를 증거하는 기록물을 통해 국민에게 봉사하며 동시에 자신의 투명성을 증명한다. 하지만 그 반대의 경우 권력은 국민을 탄압하고 불행으로 이끈다. 이처럼 기록물은 민주주의의 핵심인 권력의 균형을 위해서도 매우 중요한 역할을 수행한다. 기록물의 상징성과 역할을 고려할 때, 이들에 대한 합리적이고 올바른 관리는 궁극적으로 국민의 권리보호에 직결된다.

This study is to examine the types of expression and aesthetic characteristics of on-line game characters by analyzing those game characters' body and their costume that appear in various domestic on-line game sites. It is shown in this study that types of the human bodies and costume expressed through the game characters are grouped into five categories such as exposure and tightness, enlargement and exaggeration, curtailment and simplification, gender stereotype and unification. Furthermore, there are four typical aesthetic characteristics resulting from those types of expressions; First, 'grotesque' is expressed in the form of extreme enlargement and exaggeration, extreme exposure and concealment, combined images among human, animal or machine, or monstrous devilish images. Second, in an effort to express 'eroticism', bodies are directly exposed, see-through costumes are used in order to emphasize the body lines or very tight designs are used. Third, 'futuristic' characteristics are shown through geometrical shape and silhouette, machine-like details, strong artificial colors or glossy hi-tech material. Lastly, 'pastiche' is expressed with reconciliation of variety of costumes of game characters. Various opposite or heterogeneous styles are combined or harmonized each other to show pastiche, of which examples are male and female, superior culture and inferior one, rich and poor, oriental and western, human and machine, human and nature or past and future, etc.
