Fifteen GCMs in the Coupled Model Intercomparison Project Phase 6 are evaluated for the skill in simulating the atmospheric river (AR) frequency (FAR) and integrated vapor transport (IVT) during 1995–2014. All GCMs simulate well the annual and seasonal climatology of FAR and IVT for both the global and East Asia domains. Large biases in FAR and IVT occur in the same regions characterized by high AR activities including the midlatitude Pacific and Atlantic oceans, the Southern Ocean, and the tropical region from the eastern Indian Ocean to the western Pacific. The sign and magnitude of large model errors vary across the GCMs to result in small model-mean biases. The seasonal variation of the skill of individual GCMs is smaller than the variation of the skill across the GCMs, implying that the model skill varies more widely by the difference in model formulations than the response of individual GCMs to seasonal forcing variations. A novel method to relate the skill for simulating FAR and IVT to that for winds and water vapor is introduced. The method shows that the vertical integration of the covariance of wind and water vapor in the definition of IVT can be well approximated by the multiplication of two separate functions obtained by vertically integrating either winds or water vapor, especially in the regions of strong AR activities. Spearman’s rank correlation in conjunction with this method suggests that the model skill for FAR and IVT is significantly related only to that for winds.

김정은 집권 이후 현대북한에서는 핵·미사일에 대한 상징화 작업이 한창이다. 기념우표와 케이크는 물론 핵과 미사일에 관련된 각종 조형물과 상징물들이 평양을 가득 채우고 있다. 평양은 핵과 미사일의 이미지로 점철되는 중이다. 외부의 적이 아닌 내부의 인민들을 향한 핵과 미사일에 대한 선전공세는 다분히 정치적이고 상징적이다. 최근 북한의 핵에 대한 상징화는 그들이 사회통합의 기제로써 사용하던 상징정치의 맥락과 맞닿아 있다. 핵과 미사일이라는 기존에 북한사회에서 전면적으로 내세워 진 적이 없는 새로운 상징체계이자 기호가 등장한 것일 뿐 이 역시 상징정치의 맥락에서 분석이 가능하다. 상징에 부착된 의미의 종류와 양에 따라 인간은 상징에 반응하는 정향을 가지게 되고 이에 따라 행동이 결정된다. 정치적으로 이용되는 상징인 정치상징은 정치의 본질인 권력관계에서 피지배자가 지배자에게 “자발적으로” “순응하는” 기제로 작용한다. 이는 곧 질서를 창출하며, 상징체계는 이러한 권력과 질서의 이미지이다. 그렇다면 이러한 상징이 표명하고자 하는 것은 무엇인가? 이는 곧 상징을 창조하고 강요하는 세력, 담론을 장악하고 있는 세력이 상징에 어떠한 목적을 부착했는지를 뜻한다. 탈식민화를 거친 민족국가에서는 이와 같은 상징이 식민지시대의 아픔을 기억함과 동시에 민족국가의 정통성과 정체성을 나타내는데 주력하는 경향이 있다. 그러나 북한에서는 국가 그 자체보다 독점권력과 그 권력이 안정적으로 승계됨에 필요한 정당성에 대한 순응을 상징을 통해 강요하고 있다. 백두혈통으로 대표되는 독점권력과 혁명전통으로 대표되는 승계의 정통성은 ‘총대철학’과 ‘선군정치’에서와 같이 북한의 군사우선주의의 맥락(기조)에서 상징화되고 있다. 김정은 시대 핵·경제병진노선도 이와 마찬가지 맥락이며, 핵과 미사일에 대한 상징화 역시 기존 북한 상징정치의 역사에 흐르고 있는 승계의 정통성을 표명하며 군사우선주의의 맥락에서 이루어지고 있다고 평가할 수 있다. In North Korea, there is a symbolization of nuclear weapons and missiles. Pyongyang is awash with images and symbols related to nuclear weapons. The propaganda offensive against the people and missiles directed toward the inner people of the inner world is highly political and symbolic. Symbolic politics in North Korea is traditional and nuclear symbolization and symbolic nuclear weapons is the same. Numerous symbols face one place. The key is the succession of power and the Idolization of the leader. The essence of politics is political(power) relations. The ruler wants the follower to adapt voluntarily and the symbol makes it possible. Therefore, symbols create order. North Korea’s order is the consent of the people of power succession. The legitimacy of the monopoly power succession is symbolized by the Chong-dea Philosophy(Gun-First Philosophy) and image of Sun based on Military Priority Context such as Sun-gun Policy. The symbolism of Kim Jong-un’s Economy-Nuclear Parallel Policy isn’t different.

The biosorption characteristics of SRCM 120569 biomass on anionic Congo red (CR) dye. SRCM 120569 strain isolated from Korean turbid rice wine (makgeolli) was identified by 16S rRNA sequence analysis as Bacillus licheniformis. Bacillus licheniformis SRCM 120569 (Genbank Accession No. MW819861) showed superior CR dye biosorption capacity in an aqueous solution. Maximum adsorption capacities of 61.2 and 133.1 mg/g were obtained at pH 3.41 and 0.01 g/50 mL dried cell dosage, respectively. The CR dye adsorption properties by the Bacillus licheniformis SRCM120569 strain were characterized by Fourier transform infrared spectroscopy (FT-IR), point of zero charge (pH<sub>pzc</sub>) analysis, and phylogenetic analysis. The biosorption isotherm and kinetic models are well described with the Langmuir adsorption isotherm and pseudo-second-order kinetic models.

Simplified dynamics models have been widely adopted to reduce the computational complexity of motion planning for legged robots. However, not much research has been conducted on the collision avoidance for a simplified dynamics model. To contribute to this problem, we present the collision-backpropagation based obstacle avoidance method (CBOA), in which we employ the gradient flow of the collision cost to optimize the trajectory, thus avoiding collisions with obstacles. Our experiment shows that the CBOA reduces the collision rate of planned trajectories by up to 15.89 times compared to a previous implicit collision avoidance method.
HOW CONSTRUAL LEVEL WORKS IN THE CHOICES OF ONLINE SHOPPING MALL

This paper investigates a theoretical and experimental evidence for a niche strategy for small and medium online shopping malls to survive against large famous shopping malls dominating the E-commerce market. The present study explored both theoretically and empirically how consumers’ preferences for alternatives in online shopping context are affected by their construal level and concentrated its efforts on the verification of the phenomenon under various frames and regarding various categories(Liberman and Trope 1998; Liberman, Trope, and Stephan 2007, Liberman Trope, and Wakslak 2007). For this, this study demonstrates how chronic construal levels of consumers may affect their alternative choice for online shopping via various contexts (Experiment 1-3) and categories (Experiment 3-5). This series of experiments suggests that consumers with high construal level can be defined as a group that is relatively less susceptible to reputation of the shopping malls. Thus, strategically targeting this group of consumers will help small online malls lacking store reputation to mitigate their competitive disadvantage. Based on both existing literature and the experimental results as above, this research discusses possible methods for small online shopping malls to target high-construal segmentation.
