Culture teaching is little included in the practice of teaching Chinese to Speakers of Other Languages, which has lasted for a long time. Taking Chinese teaching in Shaanxi Normal University of China (a splendid university famous for Chinese teaching to foreigners) for example, the explanation and description of basic Chinese language uses is the most important objective in the teaching of reading, speaking, listening and writing, whereas culture teaching is very limited. This results in low motivation for students to learn Chinese, who are then unable to adapt into the local community and culture, and therefore cannot increase their Chinese standards. Based on the theory of culture intelligence firstly put forth by Peterson, one would be influenced by culture intelligence if he studies, learns, and works in a non-native language environment, and culture intelligence is closely related to culture teaching. Students with high culture intelligence could perform better than those without. This thesis is aiming at discussing the present situation of China’s Chinese teaching to foreigners and giving suggestions based on Culture Intelligence Theory. Firstly, it will discuss the concept and values of culture intelligence. After that, it will discuss the present condition of domestic Teaching Chinese as a Foreign Language and the lack of culture elements therein from the perspective of teacher, teaching and students. Finally, it will utilize Culture Intelligence Theory to make suggestions in related areas and explore students' Culture Intelligence cultivation standard as well.

Based on the relevant theories of campus culture, this paper takes the construction of universities in minority areas in China as well as the actual situation of the universities in the ethnic minority areas in China and the campus culture of neighboring countries as examples. The multi-cultural background of campus culture in ethnic minority areas is comprehensively analyzed. Through a large number of facts investigation and data research, the challenges, problems and measures to deal with campus culture construction are discussed and studied effectively. And make positive efforts to promote the construction of campus culture in ethnic minority area. Yanbian region is the main inhabited area of Korean nationality in China, which is located in the east of Jilin Province, bordering with Russia, North Korea, South Korea and Japan. It is the meeting point of the regional economy, population, and geographical center of gravity of Northeast Asia, and it is the hub for air, sea and land transport in Asia and Europe. Yanbian University is the only comprehensive university with distinct national characteristics in Yanbian area. Taking Yanbian University as the research object, it has certain representativeness to carry out the campus cultural construction under the multi cultural background, and also has certain reference function to the campus culture construction of the comprehensive universities in other ethnic regions. The conclusion will provide reference for strengthening the construction of campus culture in ethnic minority areas.

대한민국 건설현장에서 환경기술인 채용이 이루어지지 않고 있다. 제조업의 경우 대기환경보전법 제40조에 따라 사업자가 환경기술인을 임명하도록 명시되어 있다. 이와 반대로 건설 분야는 환경기술인 의무선임에 관한 법적인 사항이 존재하지 않는다. 국내 건설대기업의 경우 본사에 환경관리자를 채용하여 운영하는 사례가 있다. 하지만 본사의 환경관리자는 단위현장의 행정적인 업무 지원이나 법적 분쟁이 발생하였을 때 해결하는 역할을 할 뿐이다. 환경기술인의 의무선임은 건설현장의 일자리 창출뿐만 아니라 현장기술자의 업무를 분담하는 역할도 기대할 수가 있다. 향후 지구의 기후변화로 인한 환경 분야의 중요성은 점차 증가할 것이다. 이에 따라 공사금액 120억 원 이상의 건설공사에서 환경기술인을 의무적으로 선임한다면 청·장년층의 일자리에도 기여하며 기술자 본인의 업무영역에 집중할 수 있는 계기가 될 것이다.

Core-shell structured nanoparticles are garnering attention because these nanoparticles are expected to have a wide range of applications. The objective of the present study is to improve the coating efficiency of gold shell formed on the surface of silica nanoparticles for SiO2@Au core-shell structure. For the efficient coating of gold shell, we attempt an in-situ synthesis method such that the nuclei of the gold nanoparticles are generated and grown on the surface of silica nanoparticles. This method can effectively form a gold shell as compared to the conventional method of attaching gold nanoparticles to silica particles. It is considered possible to form a dense gold shell because the problems caused by electrostatic repulsion between the gold nanoparticles in the conventional method are eliminated.

본 연구는 금강수계의 백제보 부근에서 이･화학적 수질의 시간적 변이 파악을 위해 2004 ~ 2017년까지 측정된 환경부 수질자료를 분석하였다. 이용된 수질 변수는 전기전도도(Electric conductivity, EC), 용존산소량(Dissolved oxygen, DO), 수온, 생물학적 산소요구량(Biological oxygen demand, BOD), 화학적 산소요구량(chemical oxygen demand, COD), 총인(Total phosphorus, TP), 총질소(Total nitrogen, TN) 및 총부유물(Suspended solid, SS)의 항목으로 이들의 수질특성은 연별, 계절별로 큰 변이를 보였다. 총인 및 이온희석현상의 지표로 이용된 전기전도도는 계절별 분석에서 장마기에 크게 감소하는 현상을 보이며 강우와 역상관관계(p<0.01, n=163)를 보였으나, 계절별 총인은 갈수기에 비해 장마기에 증가하는 특성을 보여 강우와 상관관계(p<0.01, n=163)를 보였다. 한편, 생물학적 산소요구량 및 화학적 산소요구량은 강우와 유의한 관계(p>0.05, n=163)를 보이지 않았고, 계절별 총부유물 농도는 강우기에 크게 증가했고 강우와 유의한 관계(p<0.01, r=0.6155)를 보였다. 생물학적 산소요구량의 계절적 변화패턴은 화학적 산소요구량과 유사한 양상(r=0.4751, p<0.01)을 보였으며, 마찬가지로 총질소의 변화 패턴 또한 총인과 유사한 양상(r=0.0579, p<0.01)을 보였다. 보 건설로 인한 수체의 정체와 유량 증가로 인해 총인과 총질소가 심층으로 침전되어 백제보 건설 전에 비해 건설 후에 감소하는 특성을 보였고, 용존산소량은 보 건설 후에 증가하는 현상을 보였다. 4대강 사업 후 물리적 환경변화에 기인한 수질 변화 분석 결과에서 녹조량 감소를 위해서는 지속적인 총인 관리와 총인 외에도 영양염류 조절, 생물학적 산소요구량 증가를 유발하는 비점오염원관리 등이 시급하다는 것을 알 수 있다.

PURPOSES : The purpose of this study was to investigate the behaviors of the middle slab in a double-deck road tunnel subjected to construction equipment loading from such as a concrete pump car, concrete transmixer, and lifting crane. METHODS: The major construction processes of a middle slab include concrete placement, concrete transportation, and lifting of materials near the emergency passageway section. During the concrete placement, the middle slab is subjected to construction loading due to the presence of the concrete pump car and fully loaded concrete transmixer. During the concrete transportation, the middle slab is subjected to loadings from both the fully loaded and empty concrete transmixer. The emergency passageway section of the middle slab is subjected to crane loading during lifting work. The magnitudes and geometries of these construction loadings are determined and the stresses and deflections of the middle slab under these loadings are analyzed using finite element models of the middle slab. The behaviors of the middle slab under the design truck loadings are also analyzed to compare the results with those under construction loadings. RESULTS : The stresses and deflections of the middle slab under construction loadings are comparable to those under the design truck loadings. Higher stresses can be observed when the concrete transmixers cross paths at the expansion joint section of the middle slab. The behaviors of the middle slab under the construction loadings during concrete placement are very similar regardless of the section types of the middle slab such as the normal, expansion joint, and emergency passageway sections. CONCLUSIONS : When the middle slab is designed, the construction loadings should be considered to determine the primary design loads and to verify the usability of a variety of construction equipment.

PURPOSES : The purpose of this study was to suggest a quantitative trend of the daily and seasonal cyclic movement of transverse crackwidth based on measurements in CRCP(Continuously Reinforced Concrete Pavement) within the first year of construction. METHODS : Crack gauges were installed in eight normal cracks, two induced cracks, and two construction joints of newly constructed CRCP. Crack width movements were continuously collected for about a year to investigate the cyclic behavior after construction. The daily and seasonal crack width movements were quantitatively analyzed and compared. RESULTS: Crack width movement in hot weather was relatively less than in cold weather. As a result of frequency analysis of the daily cyclic behavior, it was revealed by measurement that the minimum crack width from 2 p.m. to 4 p.m. was caused by expansion of the concrete; and that the maximum width from 6 a.m. to 8 a.m. was caused by contraction. Average crack width movements were calculated for every month and showed seasonal cyclic behavior. Maximum crack width was measured from December to January. Average crack width was investigated from March to April. Daily crack width movement in relation to concrete temperature was calculated from -0.00017 to -0.03844 mm/℃ and showed gradual decrease in absolute value with time caused by change in the crack spacing. It was found that the relationships between the monthly average crack width and concrete temperature are from -0.004 to -0.012 mm/℃. CONCLUSIONS : Crack-width movement shows a daily and seasonal cyclic behavior. Crack-width measurement in any time or season will have variance caused by daily and seasonal cyclic movement. Variances and trends were obtained in this study based on measurements for various cracks. The long-term behavior of cracks should be surveyed and compared with these measurements to investigate trends of convergence with time, caused by convergence of crack spacing.

Virus-like particles (VLPs) are similar to pathogenic viruses, but because they have no nucleic acid, they have excellent safety and immunogenicity and are used as a good vaccine material. However, in the selection of various structural proteins of pathogenic viruses to form VLPs, all expression systems consume a lot of time in common. Among them, the baculovirus expression system causes additional time consumption to construct the recombinant baculovirus. Therefore, there is a need for a system that can rapidly determine the structural proteins required for effective VLP production. This study aims at solving this problem by constructing a BmNPV inducible expression platform through the construction of vectors induced by BmNPV. The platform was evaluated for overexpression using EGFP. We also confirmed the formation of virus-like particles through overexpression of canine parvovirus structural proteins.

The red imported fire ant (Solenopsis invicta) is a species of ant native to South America. The fire ant was inadvertently introduced into USA, Australia, New Zealand, and other Asian countries including China and Taiwan. Since the first report of the fire ant in port city of Busan, Korea in 2017, it was found in many other cities of Korea in following year. To obtain the molecular information of this invasive species, total RNA was extracted from the abdominal segment of the ants collected in Incheon, and subjected to transcriptome sequencing. By using Illumina sequencer platform, 101 base pared-end sequencing generated 2 × 50,064,081 of raw reads to obtain 2 × 45.95 Gbase of quality filtered nucleotide sequences. The in silico cDNA library was constructed by Trinity de novo assembler followed by TransDecoder ORF finder and CD-HIT clustering program to streamline the library. The final version of cDNA library contains 20,442 contigs with protein coding capability. To survey the virome of this ant, these contigs were searched against the viral reference sequences from NCBI RefSeq database with BLASTN program. As a result, contigs which showed high sequence identities with several RNA viruses including previously reported SINV-2 were found from the fire ant. This virome information might give an idea of a shift of virological environment of this newly found ant isolate or population in Korea.

This study investigates how newcomers to the university setting integrate lexical bundles (LBs)—frequently recurring word sequences—into their writing by analyzing the bundles’ syntactic roles (i.e., relations to larger structures). Previous studies have considered phrases and clauses as the main internal structures of LBs; however, these boundaries might not always be clear because such fragmented sequences do not stand alone, but are embedded in larger structures. The current study addresses this gap by investigating the syntactic roles of LBs identified in native and nonnative corpora of English argumentative essays (approximately 1400 essays, comprising half a million words each) written in response to identical writing prompts. The results show that the two language groups display generally similar patterns of using LBs due to their status as novice academic writers, but at the same time, their patterns do diverge to some extent, with some uses unique to or more common to each group. The extent to which different population groups use LBs in relation to the syntactic complexity typical of a given register could be indicative of their language development.

The cooperative relationship between Employer and Contractor in the construction industry is the most important factor to achieve the project success. Employer shall draw the Contractor’s cooperative behavior during executing the project. A study on the impact of the Owner’s power on the contractor’s cooperative behavior is rare in the construction industry in Korea even though the negative impact of the high-power distance between the Employer and the Contractor has been a hot issue in Korea. In this empirical study, it is shown that the Employer’s power can address the contractor’s cooperative behavior. The respondents were mostly employees in the domestic construction companies who have experienced in the construction projects. The total number of respondents was 317 effectively. The multiple regression analysis using SPSS 21.0 were conducted to verify the hypotheses. In conclusion, the Mediated Power is positively associated with the In-Role Behavior and with the Extra-Role Behavior. Some of Non-Mediated Power is positively associated with the In-Role Behavior and with the Extra-Role Behavior. It seems that the Contract underestimate the Employer’s Expert Power. It was known that the cooperative power caused by Non-Mediated Power is good for long term relationship of the business to business transaction. So it is highly recommended that the Employer shall foster its expertise.

본 연구는 한국인 학습자에게 적절한 중국어교육문법체계를 설계하기 위한 중간 단계로 중국에서 외국인 학습자를 위해 제정한 『国际大纲(语法:2014)』과 『新HSK大纲(语法:2015)』을 비교분석하여 나타나는 문제점을 찾고, 활용 방안을 모색하여 한국인 학습자를 위한 중국어교육문법체계 설계의 토대 마련에 목적이 있다. 두 요목의 비교분석을 통해서 유사한 문법체계로 상호연계성을 가지고 일부 문법항목의 등급배열, 문법항목의 용어와 기술에서 몇 가지 문제점이 있음을 알 수 있었다. 첫째, 『国际大纲(语法:2014)』과 『新HSK大纲(语法:2015)』의 원칙과 구성 체계는 모두 6등급으로 동일한 문법체계로 연계성을 지녔지만 『新HSK大纲(语法:2015)』이 『国际大纲(语法:2014)』보다 난이도가 높다. 둘째, 한국인 학습자의 특징을 반영하고 등급을 고려하여 비교문, 겸어문, 把자문, 被자문등 누적식순서배열로 배열해야 할 것이다. 셋째, 문법항목의 용어와 기술에서 조동사-능원동사, 존재문-존현문, 被자문-피동문 등 혼용되고, 사용예문도 명확하지 않았다. 이런 문법항목들은 통용성을 지닌 문법항목 용어와 개념이 정확하게 기술할 수 있도록 연구되어야 할 것이다. 이상 『国际大纲(语法:2014)』과 『新HSK大纲(语法:2015)』의 비교분석을 통해 살펴본 문제점과 활용방안을 토대로 한국인 학습자의 중국어교육과 평가가 유기적인 관계를 지닌 교육문법체계가 설계되고 나아가 한국인 학습자를 위한 통용성을 지닌 교육문법요목이 마련되길 기대해 본다.

Recently various composite beams in which concrete is filled in the U-shaped steel plate have been developed for saving story height and reducing construction period. Due to the high flexural stiffness and strength, they are widely being used for the building with large loads and long spans. The semi-slim AU composite beam has proven to take highly improved stability compared to the existing composite beams, because it consists of the closed steel section by attaching cap-type shear connectors to the upper side of U-shaped steel plate. In this study the finite element analyses were performed to evaluate the safety of the AU composite beam with unconsolidated concrete which were sustained through the closed steel section during the construction phase. The analyses were performed on the two types of cross section applied to the fabrication of AU composite beams, and the results were compared to the those of 2-point bending tests. In addition, the flexural performance according to the space of intermittent cap-type shear connectors and the location of reinforcing steel bars for compression was comparatively investigated. Through the results of analytical studies, it is preferable to adopt the yield moment of AU composite beam for evaluating the safety in the construction phase, and to limit the space of intermittent shear connectors to 400 mm or less for the construction load.
