과학기술의 발달로 인해 국민의 생활수준 향상과 건강에 대한 관심 증대 등으로 인해 화장품을 비롯한 향장품산업, 기능성식품 및 천연물 신약 등에 대한 자원식물 유래 천연물질 수요가 증가되고 있다. 자원식물을 활용한 기능성 제품의 개발은 국민의 건강증진 뿐만 아니라 국제경쟁력 강화나 윤택한 삶의 추구에도 절대적 역할을 할 것으로 기대되고 있으며, 이러한 수요에 따라 제주의 특산 또는 우수 자원식물을 활용한 생리활성 물질에 대한 연구들이 활발하게 진행되고 있다. 우리나라에 자생하는 관속식물은 총 4,500여 종으로 국가생물종목록에 작성되어 있으며 제주의 생물자원 중 관속식물은 해발 1,950m 한라산의 영향으로 2,200여 종이 분포한다고 최근 기록되고 있다. 이 중 식용 및 약용으로 활용 가능성을 갖고 있는 식물자원들도 약 800여 종이 분포한다고 보고되고 있다. 이들 자원은 대한약전, 생약규격집, 중약본초, 중약대사전 등 문헌에 근거한 자원으로 공정서에 수록된 약용식물 약 500여 종 중 제주 분포 약용식물도 217종으로 조사되고 있다. 이러한 제주의 약용식물 자원은 다양한 한의약재로 활용되고 있으며 민간약으로 활용되는 약용식물도 170여 종이 포함되어 있다. 특히, 최근에는 나고야의정서 발효에 따른 자원전쟁이 시작되어 자원식물을 포함한 생물자원 관리의 중요성이 그 어느 때보다 부각되고 있어 각 지역마다 자생 생물자원에 대한 주권을 확보하기 위한 연구들이 많이 추진되고 있다. 이와 더불어 지자체연구소인 생물종다양성연구소에서도 제주에 분포하는 자원식물들에 대한 주권 확립을 위한 생태사진 900여 종, 표본 1,400여 종, 유전자 정보 800여 종 등을 확보하고 있으며 추출물 2,000점을 확보하여 산업소재화 연구를 추진하고 있다. 저자는 여기에 제주의 자원식물을 활용하여 화장품 원료등재, 건강기능식품개별인증 소재 및 천연의약품 소재 등 산업소재화 연구를 수행했었던 생물종다양성연구소의 연구 결과를 소개함으로써 유사한 목적으로 연구를 수행하는 대학, 연구소 및 기업으로의 정보를 제공하여 제주의 자원식물을 활용한 산업소재화 분야에 작은 도움이나마 제공하고자 한다.

The purpose of this study is two-fold: first, to examine the current status of e-dictionary use in Korea and the attitude toward its use by Korean college students; second, to investigate to what degree e-dictionaries may be useful and effective tools in helping to improve learners' overall English skills. The subjects were 84 college students and they were divided into two groups: the experiment group and the control group. The instrument employed was the Preliminary Student Usage Questionnaire, which was developed by the researcher, together with the questionnaire survey developed by Koyama and Takeuchi (2004), which was modified for the study. The findings from this research are as follows: First, a special instruction session on how to use e-dictionaries made a statistically significant difference among users of the dictionaries. Those subjects who had received the instruction displayed a more positive attitude toward the use of e-dictionaries. Second, the experiment group showed a more favorable attitude toward the use of e-dictionaries. On the basis of the above results, the researcher suggests that proper guidance on the use of e-dictionaries and their benefits should have a positive influence on users. The findings from the current research will shed light on the current status of electronic dictionary use among Korean college students.

This study is to develop a named entity recognition model specialized in criminal investigation domains using deep learning techniques. Through this study, we propose a system that can contribute to analysis of crime for prevention and investigation using data analysis techniques in the future by automatically extracting and categorizing crime-related information from text-based data such as criminal judgments and investigation documents. For this study, the criminal investigation domain text was collected and the required entity name was newly defined from the perspective of criminal analysis. In addition, the proposed model applying KoELECTRA, a pre-trained language model that has recently shown high performance in natural language processing, shows performance of micro average(referred to as micro avg) F1-score 98% and macro average(referred to as macro avg) F1-score 95% in 9 main categories of crime domain NER experiment data, and micro avg F1-score 98% and macro avg F1-score 62% in 56 sub categories. The proposed model is analyzed from the perspective of future improvement and utilization.

To cope with the potential risks associated with invasive alien species, the Korean Government implemented the Biodiversity Act in 2014. Among the alien species not yet introduced into that country, 24 have been designated as alert species. These include mammals, birds, fish, mollusks, insects, and plants that may invade and cause serious harm to the ecosystem. Approval from the Ministry of Environment is required to import or carry any of them. Although these measures are more advanced than those from the previous legal framework, several terms still need to be improved. First, the category of alert species should cover not only those not yet introduced but also those that are being raised or cultivated at aquariums, botanical gardens, and zoos. Second, for applicants who intend to import or carry alert species, the government must provide them with detailed standards for the ecological risk assessment of alert species as well as guidelines for their safe use in Korea to prevent their unregulated release from confinement facilities into natural environments. Third, tools and protocols should be developed for early detection and rapid responses to those escapes.

농림수산식품부는 지속적으로 소비가 증가하고 있는 오리고기의 위생적 관리 및 생산성 향상을 위해 축산업 등록대상에 '종오리업'을 신설하여 축산업등록을 의무화하고, AI상시방역 체계구축과 사전 가축질병예방을 위해 '양계업'과 '오리사육업'의 축산업 등록대상 규모를 현행 $300m^2$이상에서 $50m^2$이상으로 확대하는 등을 주요 내용으로 하는 "축산법시행령"이 2008년 12월 24일 개정 공포되었다고 밝혔다. 축산업 등록대상 : (1)부화업 (2)계란집하업 (3)종축업(종돈업, 종계업, "종오리업") (4)대통령령으로 정하는 규모의 소사육업, 양계업, 그 밖에 대통령령으로 정하는 가축사육업 또한, 축산발전기금의 융자사무 취급기관을 농협 은행에서 새마을금고와 신용협동조합으로 확대하여, 농업인들이 편리한 금융기관을 선택 이용할 수 있게 되었다. 농림수산식품부는 앞으로도 의견 수렴을 통해 축산농업인의 불편사항을 해소하고, 위생적이고 안전한 축산물이 국민들에게 공급될 수 있도록 지속적으로 제도개선을 추진해 나갈 예정이다.

In next generation wireless network environment, various different wireless access technologies exist and multi-interface systems which can provide various services in one terminal are required. So far there have been many studies only on the power control part of multi-interface systems. Therefore, the study of network connection considering Qos between different networks is necessary in order for various services to be operated in integrate wireless networks. This paper proposes a pre-authentication and network connection mechanism rather than power control part.

The corrosion of reinforcement is the main reason for the performance degradation of concrete structures. The pre-rusted parts of rebar in concrete structures are vulnerable to the corrosion, especially if the structure is exposed to wet or chlorinated environments. In this study, effects of different curing solution on corrosion behavior of the pre-rusted rebars in the cement composites were investigated. HCl(3%) and CaCl₂(10%) solution were utilized to accelerate the pre-rust of the rebar, and each pre-rust condition rebar including reference (RE) were placed in mortar cylinder. Three kinds of samples then were cured in CaCl₂ (3%) solution and tap water respectively for 120 days. Electrochemical polarization and half-cell potential measurement were used to monitor the influence of curing water on the corrosion behavior of pre-rusted steel bar in cement composite. The surface morphology and composition of corroded steel bar were analyzed by scanning electron microscope and energy dispersive X-ray diffraction. The results show that the corrosion rates of pre-rusted samples in both curing water are higher than that of non-pre-rusted samples. The corrosion rates of RE, CaCl₂ and HCl pre-rusted samples in salt water were 8.14, 4.48, 13.81 times higher than those in tap water respectively, on the 120th day.

As a study for offshore wind farm, we investigated the fish fauna of the Wi-do, Younggwang-gun, Chollabuk-do, Korea. From the four times collection of fish species from October 2013 to June 2014, we collected 46 species of 26 families including 9 orders. Among them, the fish of family Gobiidae includes the most number of six species (13.6%). The dominant species was the Argyrosomus argentatus with 53.10%. Total of 17 fish species, including the Cynoglossus joyneri were collected from all of four collecting sites. On the other hand, 13 species including Inimicus japonicus were collected from only one site. Being the wind farm under construction, fish will temporary decrease in this area. But in the long term, we think that Oplegnathus fasciatus, Sebastes shlegelli and others will increase with good inhabited environment provided by the wind farm structures.

Phytoliths formed on the leaf-blades of the seventeen Oryza species were examined using back-scattered electron imaging. The resulting descriptions of the phytoliths became the basis for a new key to the species of the genus. This key includes features useful for specific identification related to the silica bodies originating from epidermal cells upon both the mid-vein and bulliform cell, as well as of phytoliths originating from papillae, prickle hairs, large and small trichomes, and stomatal apparatus. These detailed phytolith descriptions, back-scattered electron images, and keys to both adaxial and abaxial sides of leaves, can now be used in identifying phytoliths from archaeological samples as well as extant species of Oryza.
