In his book Worlds and Individuals: Possible and Otherwise, Takashi Yagisawa Yagisawa argues that his own theory is better than Lewis's theory by showing that his own theory can deal with important objections to modal realism more successfully than Lewis's. In particular, Yagisawa claims that by adopting modal tenses, he can respond to many important objections to modal realism in a uniform way. In this paper, I argue that Lewis can also successfully respond to Peacocke's objection in an exactly parallel way to Yagisawa's by distinguishing existence at the actual world from existence at other possible worlds and that Yagisawa's response to van Inwagen's objection does not succeed. I conclude that Yagisawa fails to show that his own theory is better than Lewis's.

Purpose: This study analyzed the perception and importance of country-of-origin labeling at restaurants in 500 college students in Jeju surveyed from April 15 to May 5, 2016 with the aim of providing basic data. A total of 465 questionnaires out of 500 were used as base data for this study. Methods: The data were analyzed using descriptive analysis, ${\chi}^2-test$, and t-test using the SPSS Win program (version 21.0). Results: Regarding food safety-related dietary behaviors, average score was 3.65 points (out of 5), and 'put the food in a refrigerator or freezer immediately (4.07)' showed the highest score, whereas 'cool rapidly hot food prior to putting it in the refrigerator (3.08)' showed the lowest score. Regarding the awareness of country-of-origin labeling at restaurants, 67.5% of subjects were aware of it. With regard to dietary behavior of food safety, the high group showed a higher score than the low group (p < 0.001). Regarding reliability of the system, 4.9% of subjects indicated 'very reliable' and 45.4% 'somewhat reliable'. For perception of subject's country-of-origin labeling, the average score was 3.77 (out of 5). Regarding checking country-of-origin labeling at restaurants, 68.0% of subjects checked country-of-origin labeling, and the high group in the safety-related dietary behavior score ranking showed a higher rate (79.3%) than the low group (57.1%) (p < 0.001). With regard to importance by item, 'honest country-of-origin labeling of restaurants' showed the highest score at 4.27 (out of 5). Conclusion: It is necessary to provide continuing education for college students in order to enhance their perception of country-of-origin labeling at restaurants. Moreover, a systematic and appropriate support and control system by the government and local government needs to be developed in order to improve country-of-origin labeling at restaurants.

한국어 용언의 형태소 정보처리의 특성을 규명하기 위해 피동의 처리 양상을 살펴보았다. 한국어의 피동문은 용언에 파생접사가 붙어 이루어지는 경우와 '-어 지다'와 같이 구문 변형에 의해 이루어지는 경우로 나눌 수 있다. 본 연구에서는 이 중 피동 파생접사 '-이, -히, -리, -기'가 붙은 피동사만을 선정하여 고려대학교에 재학중인 일반인 학생을 대상으로 점화어휘판단 관제를 실시하였다. 실험조건은 표면적 형태와 기능으로 구분하여 4조건으로 설계하였고 SOA는 150msec과 750msec로 나누었다. 실험 결과 피동('어근+파생접사')의 정보처리는 선행연구의 '어간+(시제)선어말어미'의 결과와 유사한 형태를 보였으며, '어간+(연결)어말어미'와는 다른 결과를 보였다. 이런 결과로 미루어보아 어근과 접사는 각각 따로 저장되어 있다기보다는 '어근+접사'의 형태로 심성어휘집에 저장되어 있는 것으로 보인다. 기존의 형태소 분석에서 거론되고 있는 Fullist, Decomposition, Hybrid의 세 가지 모형으로는 한국어 용언의 다양한 표상 및 처리 과정을 설명하기 어려우므로 새로운 모형을 제시하고자 한다.

지난 해 전 세계적인 금융쇼크로 인해 올해 국내 육계산업에도 적지 않은 영향을 끼쳤다고 볼 수 있다. 고환율로 인해 수입닭고기가 시장에 형성되지 못하고 정부에서는 농산물의 원산지표시제를 시행함으로써 국내산 닭고기 소비에 영향을 주었다. 더구나 우리 양계농가의 노력으로 올해는 고병원성 조류인플루엔자가 발생하지 않아 닭고기 소비도 꾸준함을 보였다. 하지만 외국에서 전량 수입되는 사료는 국제곡물가격의 인상으로 농가의 수당생산비가 상대적으로 증가되는 양상을 보였고 수입원자재도 동반상승하여 육계농가는 이중고를 겪어야만 했다. 뿐만 아니라 종계의 생산성 하락으로 병아리가격이 연중 700~800원으로 형성됨에 따라 실용계병아리의 품질이 관심의 대상이 되었으며 이런 현상은 당분간 지속될 것으로 보인다. 가금신종질병이 전국적으로 발생함에 따라 실제적으로는 육계농가의 수익은 평년보다 그리 높지 않은 것으로 파악된다. 이렇게 2009년은 육계인에게는 다사다난했던 한해로 기록될 것이며 한 해 동안 일어났던 4가지 이슈들을 정리해보았다.

한영 기계번역 시스템을 구현하기 위해서는 다양하게 활용하는 한국어 용언을 보다 효율적으로 처리해야 할 필요가 있다. 한국어 용언은 그 활용이 매우 다양하여 활용에 따라 문장 내에서 다양하게 기능하게 된다. 한영 기계번역 시스템에서는 용언의 활용이 가지는 여러 정보를 효율적으로 분석하여 해당정보를 보다 효과적으로 역문에 반영시키는 연구가 필요하다. 본 논문에서는 용언의 활용에 따른 여러 정보-시제에 관한 정보(선어말어미 관련), 문종에 관한 정보(어말어미 관련), 양상에 관한 정보(보조용언, 어말어미 관련) 등-를 통일된 코드를 이용하여 일괄적으로 처리하는 방법론과 그 과정을 제시한다.

In this paper, I would like to reconsider the evidential category (or the mediation category) in languages with language specific values, especially in Korean and French evidentials. We tried to analyze how the evidentials are represented in both languages including their linguistic markers (grammatical, lexical or discursive) and their semantic meanings. According to the precedent studies from the general linguistic point of view, we would like to reconsider the semantic meanings of both languages' grammatical markers, the so-called Korean retrospective marker '-te-' and French conditionals in the framework of the enunciative operation theory suggested by $Descl{\acute{e}}s$ & $Guentch{\acute{e}}va$ (2000), which proposed to classify the type of discourse by the language-independent description tools conceived after the enunciation theory suggested by Bally (1965), Benveniste (1956), Culioli (1973). Through this approach, we would like to contribute to establishing the linguistic basis not only for the general linguistic research to determine the invariant meaning of linguistic evidentials and their system, but also for the applied linguistics to the language engineering field.

This study was done to determine if there is any difference in microleakage between experimental composite resins, in which various proportions of three component photoinitiators (Camphoroquinone, OPPI, Amine) were included. Four kinds of experimental composite resin were made by mixing 3.2% silanated barium glass (78 wt.%, average size; 1 ${\mu}m$) with each monomer system including variously proportioned photoinitiator systems used for photoinitiating BisGMA/BisEMA/TEGDMA monomer blend (37.5:37.5:25 wt.%). The weight percentage of each component were as follows (in sequence Camphoroquinone, OPPI, Amine): Group A - 0.5%, 0%, 1% / Group B - 2%, 0.2%, 2% / Group C - 0.2%, 1%, 0.2% / Group D - 1%, 1%, 2%. Each composite resin was used as a filling material for round class V cavities (diameter: 2/3 of mesiodistal width; depth: 1.5 mm) made on extracted human premolars and they were polymerized using curing light unit (XL 2500, 3M ESPE) for 40 s with an intensity of 600 mW/$cm^2$. Teeth were thermocycled fivehundred times between $50^{\circ}C$and $550^{\circ}C$for 30s at each temperature. Electrical conductivity (${\mu}A$) was recorded two times (just after thermocycling and after three-month storage in saline solution) by electrochemical method. Microleakage scores of each group according to evaluation time were as follows [Group: at first record / at second record; unit (${\mu}A$)]: A: 3.80 (0.69) / 13.22 (4.48), B: 3.42 (1.33) / 18.84 (5.53), C: 4.18 (2.55) / 28.08 (7.75), D: 4.12 (1.86) / 7.41 (3.41). Just after thermocycling, there was no difference in microleakage between groups, however, group C showed the largest score after three-month storage. Although there seems to be no difference in microleakage between groups just after thermocycling, composite resin with highly concentrated initiation system or classical design (Camphoroquinone and Amine system) would be more desirable for minimizing microleakage after three-month storage.

This study was aimed to investigate whether an oxygen inhibition layer (OIL) is essential for the interfacial bonding between resin composite layers or not. A composite (Z-250, 3M ESPE) was filled in two layers using two aluminum plate molds with a hole of 3.7 mm diameter. The surface of first layer of cured composite was prepared by one of five methods as followings, thereafter second layer of composite was filled and cured: Group 1 - OIL is allowed to remain on the surface of cured composite; Group 2 - OIL was removed by rubbing with acetone-soaked cotton; Group 3 - formation of the OIL was inhibited using a Mylar strip; Group 4 - OIL was covered with glycerin and light-cured; Group 5 (control) - composite was bulk-filled in a layer. The interfacial shear bond strength between two layers was tested and the fracture modes were observed. To investigate the propagation of polymerization reaction from active area having a photo-initiator to inactive area without the initiator, a flowable composite (Aelite Flow) or an adhesive resin (Adhesive of ScotchBond Multipurpose) was placed over an experimental composite (Exp_Com) which does not include a photoinitiator and light-cured. After sectioning the specimen, the cured thickness of the Exp_Com was measured. The bond strength of group 2, 3 and 4 did not show statistically significant difference with group 1. Groups 3 and 4 were not statistically significant different with control group 5. The cured thicknesses of Exp_Com under the flowable resin and adhesive resin were 20.95 (0.90) urn and 42.13 (2.09), respectively.
