We examine the meanings of two plural forms in Korean. Kwak (2003) and Jun (2004) claimed that unmarked (i.e. zero) plural forms denote groups and 'deul' plural forms denote sums, and Kang (2007) indicated problems in such claims. Soon after, Jun (2007) raised an objection to Kang's view by slightly modifying his former analysis, and now this paper is a reply to Jun (2007). Jun's revision of his former view is one step forward but still it is faced with many authentic counter examples. In the mean time, Noh (2008) raised an objection to Kang (2007) from a totally different direction, claiming that unmarked forms are not plural but only singular. This position is not sound, either. We have so many cases where unmarked forms are used with plural interpretation. All in all, our view that unmarked forms denote singular as well plural individuals(sums, groups) and 'deul' forms denote only plural individuals(sums, groups) is to be maintained.

We examine semantic properties of Korean plural expressions and how they are related to genericity and definiteness. First of all, Korean plural expressions provide a strong evidence for the plurality theory which discerns between the two sorts of plural individuals such as sum and group. Sum and group are clearly distinguished by morphological markers in Korean i.e., 'tul-plurals and ${\phi}$-plurals correspond to sum and group interpretations respectively. Second, the treatment of Korean bare singulars(=${\phi}$-plurals) as group accounts for why Korean generic NPs prefer bare singulars to bare plurals. Generic NPs refer to kind, and kind is a special group derived from supremum, therefore both generic NPs and bare singulars refer to group, and generic NPs are realized as bare singulars rather than bare plurals in Korean. Finally, in Korean, plurality and definiteness have little effect on each other although some connection between them has often been reported in the literature.

발전소 복수기의 열전달 표면에 형성되는 불순물의 fouling factor와 튜브내면에 부착되는 피막의 두께변화를 측정하여 복수기 관리에 관한 지침을 제시하고자 모델복수기를 이용하여 60일간 현장실험을 실시하였다. 복수기의 fouling factor는 시험 후 약 40일 이후부터 큰 폭으로 증가하였다. 발전용 복수기의 관청결도가 85-90%로 설계되므로 설계치를 유지하기 위해서는 약 40일 마다 복수기튜브를 세정하여 관청결도를 향상시켜야 할 것으로 판단되었다. 또한 동합금 재질을 사용하는 복수기튜브는 설치 후 보호피막이 형성되는 초기 30일 동안의 방식운전이 복수기튜브 건전성 확보에 중요한 인자임을 유추할 수 있었다.

Because there are no isolation valves in condensate system of nuclear power plants, circulating water pump was shutdown for the condenser repair. When circulating water pump was shutdown, power plant output decreased about 45%. These output decreasing can minimize by establishing isolation valves. In this paper, evaluated effect to flow conditions change of condensate system, structural integrity of system, condenser pressure of in case of establish isolation valves to condensate system. Results of the evaluation, the flow rate due to the installation of the isolation valve decreased 0.3% when the valve was fully opened and 4.5% when fully closed. In addition, it was found that the vacuum degree of the condenser decreased with decreasing flow rate, but the integrity of the system was maintained.

Ascites is a condition in which body fluids are abnormally accumulated in the fish's abdominal cavity, and is an important indicator of the health of flounder. Ascites can occur in the process of infection with bacteria, viruses, parasites, etc., which causes abdominal distension, sluggish growth, and weight loss. In this paper, we tried to find the correlation with other symptoms or diseases that affect ascites symptoms in flounder. As experimental data, ascites symptoms were divided into three states: no ascites, ascites transparent, and ascites opaque, and disease diagnosis data of cultured flounder collected for 7 years were used. After performing an appropriate preprocessing process for the random forest machine learning method, other symptoms and disease factors related to ascites were extracted, and it was confirmed that the proposed model could present the main factors related to ascites.

This article compares two different auction designs for $CO_2$ emission allowances, namely uniform pricing and multiple pricing, in view of market efficiency. Experimental economic method of Buckley et al. (2004) is applied in this analysis. As a result of this analysis as expected, multiple pricing method brings out Winner's curse. It means that uniform pricing method is more efficient than multiple pricing method.

This research was to investigate the role of message regulatory focus on the advertising effect of multiple models. The multiple models are limited to two models in one advertisement in this research. This research investigated the hypothesis that multiple models, in terms of multiple source effect and social consensus, appears specifically to enhance the relationship of consumer and commercial models on the conditions of promotion-focused message which leads to the information processing of relational elaboration. This research applied a between-subjects factorial design targeting 2(the number of model: single model vs. multiple models) by 2(message regulatory focus: promotion-focused message vs. prevention-focused message). As a result, multiple models showed more positive ad attitude, brand attitude, and purchase intention than did single model. And promotion-focused message with multiple models showed more positive ad attitude, brand attitude, and purchase intention than did prevention-focused message with multiple models. Also there was an interaction effect between the number of model and the type of message regulatory focus. It wasn't fully supported that there is no difference of advertising effect between promotion-focused message and prevention-focused message on the condition of single model.

The simultaneous operation of multiple UAV's makes it possible for us to raise the mission accomplishment and cost efficiency. For this we need an easily scalable control algorithm, and swarm intelligence having the characteristics such as flexibility, robustness, decentralized control and self-organization comes into the spotlight as a practical substitute. In this paper the features of swarm intelligence are described, and various research results are introduced which show that the application of swarm intelligence to the control of multiple UAV's enables the missions of surveillance, path planning, target tracking and attack to be accomplished efficiently by simulations and tests.

Chylous ascites is a rare condition caused by various diseases and conditions that interfere with the abdominal or retroperitoneal lymphatics, and uncommonly it can manifest as a post-operative complication after abdominal, retroperitoneal or mediastinal surgery. Chylous ascites can be diagnosed by a high triglyceride content in ascites. The authors experienced a 5-year-old girl with congenital hepatic fibrosis who presented with chylous ascites after a splenorenal shunt operation, who was successfully managed by fasting and total parenteral nutrition, followed by a lipid-free diet with medium chain triglyceride supplementation. Here, the authors report this case of post-operative chylous ascites after a splenorenal shunt (Warren shunt) operation with a review of the pertinent literature.
