Purpose: To report a case of abducens nerve palsy after a percutaneous nerve blocking procedure for trigeminal neuralgia. Case summary: A 35-year-old female complaining of stabbing pain in the right maxillary area 4 months in duration was diagnosed with trigeminal neuralgia at a pain clinic. The patient underwent a percutaneous trigeminal nerve blocking procedure using alcohol at the right maxillary nerve. After the procedure, the patient was referred to an ophthalmologic service for horizontal diplopia and abduction defect of her right eye. Her corrected visual acuity, intraocular pressure, pupillary response, anterior segment and fundus were normal bilaterally. The patient had right esotropia of 38 prism diopters in primary gaze (70 prism diopters in right gaze, 20 prism diopters in left gaze) with limited abduction of -3 in the right eye. She was diagnosed with abducens nerve palsy of the right eye. Three months after initial presentation, the patient had intermittent esotropia of 4 prism diopters at right gaze and orthophoria at the other diagnostic gazes; she presented no diplopia. Conclusions: In the present case study, abducens nerve palsy following a percutaneous trigeminal nerve blocking procedure resolved over 3 months. Because the abducens nerve is adjacent to the trigeminal nerve near the foramen ovale based on anatomical structure, when performing a percutaneous trigeminal blocking procedure, the surgeon should be aware that deep needle puncture could cause abducens nerve palsy.

Purpose: To report the results of surgical repairing of inferomedial orbital wall fractures accompanied with loss of bony strut by an overlapping method using Resorb X<sup>® plates (poly(D,L)-lactic acid). Methods: To repair inferomedial orbital wall fractures with loss of bony strut, we bent the medial aspect of the plate for floor fracture according to the anatomical structure and then inserted the floor implant, which was supported by anterior, posterior and lateral margins of the floor fracture. Then, the medial implant, which was supported by the bent medial edge of the floor implant, was inserted. Postoperatively, we analyzed the outcomes of 21 patients regarding postoperative enophthalmos, limitation of eye movement (LOM) and diplopia. The diagonal lengths of the orbit in the operated side were compared with the non-traumatized side based on the coronal view of the postoperative CT scans to determine the success or failure of the reconstruction. Results: The average postoperative enophthalmic value was 0.5 mm, and no significant differences between the orbital diagonal lengths of the operated and non-operated eyes were observed. The LOM shown in 7 out of 8 patients was completely resolved during the postoperative follow-up period. All patients with diplopia, including one patient who showed partial remission of LOM, experienced complete symptom resolution. No other complications related to the implant were recorded. Conclusions: Inferomedial orbital wall fractures with the loss of bony strut can be successfully repaired by the overlapping method using Resorb X<sup>® implants.

Although Sumunmulbangdui wetland at the Halla Mountain in Jeju Island, a kind of montane wetlands, has been considered to bear high biodiversity, no study has been reported on the bacterial diversity. In this study, soil and water samples were collected from the wetland in order to isolate novel bacterial species. Bacterial strains belonging to the phyla Bacteroidetes, Firmicutes, and Actinobacteria were isolated after spreading soil and water samples onto solid agar media. The 16S rRNA gene sequences of the strains assigned to the three phyla were compared to those of type strains of the species in the phyla. The strains that showed less than 98.7% 16S rRNA gene sequence similarity to the validly published species were considered to be novel species candidates. A total of 32 strains were regarded as novel species candidates in the phyla Bacteroidetes, Firmicutes, and Actinobacteria. Diversity of novel species candidates was very low; the candidates were confined to only few genera. In the Bacteroidetes, 13 novel candidate species were affiliated with the genera Mucilaginibacter, Sphingobacterium, Pedobacter, Flavobacterium, and Chryseobacterium. A total of 13 novel candidate species that assigned to the genera Paenibacillus, Lysinibacillus, and Bacillus were identified in the phylum Firmicutes. Only two candidate species that belonged to the genera Mycobacterium and Nocardia were excavated in the Actinobacteria. Cultural, physiological, and chemotaxonomic characteristics have been determined for the novel species candidates, and the characteristics are described in this study.

멀티채널 환경에서 소비자는 어떻게 정보를 탐색하는가?: 선호하는 정보원천에 따른 소비자 유형화와 관련 요인

소비자들이 정보를 얻을 수 있는 정보채널이 다양해짐에 따라, 소비자의 정보탐색행동 또한 다양한 양상을 보이 고 있다. 이러한 맥락에서 온라인 커뮤니티와 블로그, SNS 등 새로운 형태의 온라인 정보채널과 오프라인 매장 등 기존의 정보채널을 소비자들이 어떻게 조합하여 사용하는지에 대한 연구가 필요하다. 또한 기존의 연구들에서 사용 되던 정보원천의 분류기준이 현 상황에 적합한지 여부도 재고되어야 한다. 이에 본 연구에서는 소비자들의 전반적 인 정보탐색 현황을 살펴보고, 소비자들의 정보탐색행동을 기준으로 소비자유형화를 실시하였다. 그리고 각 소비자 유형에 따라 정보탐색행동을 차별화하도록 하는 요인들을 파악하고자 하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 온라인 소비자들은 온라인과 오프라인 정보채널을 넘나들며 다양 한 정보를 탐색하고 있었다. 소비자들은 온라인 정보원천을 보편적으로 활용하고 있었으며, 그 중 구매가 이뤄지는 온라인쇼핑몰에 게시된 정보의 이용비율이 가장 높았다. 둘째, 소비자들의 정보탐색행동에 기반하여 소비자유형화를 실시한 결과, 소비자들은 ``다양한 정보 선호자``, ``객관적 정보 선호자``, ``대인적 정보 선호자``, ``집약적 정보 선호자``, ``오프라인 정보 선호자`` 등 총 다섯 유형으로 분류되었다. 각각의 소비자 집단은 정보탐색량과 활용한 정보원천의 종 류와 분포에서 차이를 보였는데, 이는 곧 소비자의 정보탐색행동은 ``얼마나 많은 정보원천을 활용하여 정보를 획득 하는가?``와 ``어떠한 정보원을 활용하였는가?`` 등 두 층위에서 고려되어야 함을 의미하는 결과였다. 마지막으로 소비 자의 정보탐색행동에 영향을 미치는 요인에 따라 정보탐색량과 주로 활용하는 정보원천이 달라졌다. 우선 소비자의 전체적인 정보탐색량은 소비자의 정보탐색성향과 쇼핑무관심성, 쾌락지향성 등에 의해 결정되었으며, 어떤 정보원천을 위주로 탐색하는지는 성별과 연령 등 사회인구학적인 변수들과 어떤 상품을 구매하였는지가 주요한 요인들로 나타났다. 본 연구의 결과를 토대로 소비자와 소비자의 정보탐색행동에 대한 이해의 폭을 넓힐 수 있으며, 소비자정보 와 관련한 커뮤니케이션 방식에 대한 시사점을 도출할 수 있었다. Recently, businesses face new challenges of internet which has been discussed to have potential as a medium for extending the range of consumers` information sources. Via the newly introduced media such as blogs, SNS businesses are trying to interact market and its consumer. For example food company ``Pulmuone`` runs a blog. It is not only for a publicizing and promoting its brand or for e-commerce, but also for interact with consumers. Specifically it focuses consumergenerated information, how its products are used in the context of consumption. Official company blogs when first introduced, were only used as a marketer-driven consumer information source, but now we can easily find consumer-generated information. Moreover even individual consumer blogs posted recommendations and product reviews in a form ``a consumer`s view`` sometimes that are the result of featured or sponsored. For instance, one of ``power bloggers`` imposed a fine for not clarifying corporate sponsorship in 2011. As such the distinctive line that separated marketer-driven information source from consumer- generated information source is now blurred. These kind of mixed status makes consumer confused. Even though the typology of information sources are becoming more complex, most of the studies did not consider consumers` information search behavior in various information channel environment. Moreover previous studies applied the outdated framework for categorizing information sources: market-driven information sources, neutral information sources, consumer generated information sources. In early 2000`s, there was a discussion about the classification of consumer information source within internet era, but the discussion was limited to the internet as a platform, and thus focus was placed on offline or online. The framework for analyzing consumer information sources currently used does not guarantee adequacy in the present market environment, since it lacks considerations for unique traits and benefits of various information channels. Thus, it is necessary to explore consumers` information search behavior with an advanced approach. It is important to understand how individuals perceive the range of information channels available to them and how those perceptions affect their use of different types of sources. These attempts enable us to draw the new standards for consumers` information sources. This study investigates consumers` use of new and traditional information sources, and identify new typology of consumers based on their choice of information channels. The major findings of this study are as follows. First, our results show that the distinction of online consumers and offline consumers may no longer be useful, since most consumers were found to use both channels. Respondents tended to use online information sources more than offline sources, and online shoppingmall was found to be the most preferred information channel. Second, consumers were a classified into 5 clusters; ``heavy searchers``, ``objective information searchers``, ``interpersonal information searchers``, ``infomediary searchers``, ``offline information searchers``. Each consumer segments were significantly different from the amount of information search and sources or patterns of information search. ``Heavy searchers`` are trying to find extensive information over diverse information sources except for offline channel based information. ``Objective information searchers`` are also heavy information users like ``heavy searchers``, but they favor price comparison site and articles. ``Interpersonal information searchers`` highly rely on interpersonal sources such as online communities, families and friends. ``infomediary searchers`` contain the largest number of individuals who do not utilize information except for detailed information that are posted by online shopping mall. ``Offline information searchers`` are consisted with whom trust offline channel so that they can confirm the products. Third, multinomial-logit analysis was conducted to explore the impact of the consumers` demographic variables, purchased goods, and consumers` shopping propensity, on consumers use of information channels. Total amount of information search was impacted by consumers` information seeking propensity, shopping indifference, and their hedonic value. Which information source were selected and used for the consumers` decision making, were largely depended on consumers` gender, age and the purchased goods. The results of this study will provide significant insights for the effective communication strategies for the consumer information providers such as marketers and the governors.
