The purposes of this survey are to collect and analyze basic data on freshmen, to understand students' general matters and to utilize the data as basic materials for student guidance and administration; to find out the students' general matters, we asked freshmen about their psychological character, values, university life, impression and pride on university, the reason for choosing their majors, whether they will keep studying, the relations with professors, life in their high school, social relationship, the point of view on social issues, and to what extent they turn to the consultation service center. The survey was conducted among 2,832 freshmen during the orientation course in 2004, and 1,812 students (64% of the total) answered. The results are as follows; 1. Most freshmen live in Jeju. The number of students from other regions and cities is also increasing gradually, so the university should create conditions to accommodate those who want to use the dormitory 2. The increase in students who have entered the university after taking entrance examination more twice indicates that they want to pursue a study in line with their aptitude. Most students' supporters are their fathers. 84.8% of the respondents have both a father and a mother. which shows that broken families became a serious social issue. The educational background of parents is getting higher. They are mostly engaged in agriculture, fisheries, and forestry. Many students' family income is over 1.5 million won a month, but a lot of students do not know about their financial status, showing their indifference in home economy. 3. Most of the freshmen replied that they live happily with their family. As to the relationships with their parents, most were positive, but some students feel uncomfortable with their parents or even say their parents do not care about them. 4. About their mental and emotional status, 73.4% showed a positive response. Their tuition fees and living expenses are primarily covered by their parents, but the number of such students has decreased compared to last year. 5. Their motivation of university entrance is to get well-paid jobs, develop their abilitiesand acquire professional knowledge. They want to make many friends and study hard. 79.5% of respondents said they want to study or travel abroad. Accordingly, the authorities need to offer as many chances as Possible. 6. Most students do not want to live in the dormitory, and many (43.9%) want scholarship and part-time jobs to pay tuition fees and other expenses so that more funds and programs for scholarship should be secured. Most of the freshmen are satisfied with the CNU website. They want to study a major that can be related to the career to pursue. 7. Some respondents said they will join clubs for their hobby or sports because they want to make many friends and do much experience. Others said they do not want to join any club because they do not feel any need. Programs to encourage students to participate in a club: should be developed. 8. They think; what is important in their life is leading a financially stable life and the exertion of their ability, and the attitude they have as a college student is to prepare themselves to become an able member of society and intellectuals. 9. The freshmen had a good impression on Cheju National University (CNU) before entering the university, but most of them do not know well about CNU, which means public relations were not enough: What they took into account when applying was the possibility of success given their scores. Their aptitude and qualifications were second. They got information on the university mostly from the website of CNU. This reminds us of the importance of on-line homepages. On the other hand, the university exposition tour arranged by CNU turned out to be of little help to applicants. 10. The publicity commercial conducted every November- December does not attract attention from students. Among means of public relations targeting students living outside Jeju, nationwide, mass media or in-person visit to high school bear good result. Publicity activities need not only efforts of officials in charge but also attention of all staff, faculty and students of the university. 11. Most of the freshmen are proud of entering CNU. They decide their major whey in their third year of high school or during the applying period. The number of students who decided their major when they were in middle school is on the decrease, which indicates that students select their major without discretion instead of setting a goal in advance and trying to achieve it. 12. Freshmen are satisfied with their major. However, they neither know well about a transfer system nor a double major system. As to double major, the most preferred second major is education. The reason for pursuing double major is to have more chance of employment, which shows students understand the difficulty in getting a job from the beginning of entrance. 13. The students expect advice on fields of study as well as close relations from them. The students have relatively integrated relations with others. They prefer lecturer-centered or experiment classes. When faced with troubles, they talk to their friends or mother, in some cases to their siblings and father. The social relations are largely good, but 4.1% confessed to their problem in relations with others. Programs for relationship development and improvement are needed. 14. Freshmen consider efforts and capability as the requirements for social success. They picked unemployment as the most serious problem faced with Korean society. They consider poor local development and backward cultural facilities as challenges faced by Jeju. Therefore, social and political leaders are urged to realize the situation and deal with regional development of Jeju with caution. 15. The students want to get advice from the consultation service center on personal problems. What they want to talk about are jobs, scholastic performance and graduate schools. They want to take aptitude tests. They are also thinking about volunteering to help others. Many students want to build their social experience through volunteer public service, so various service programs should be develop.

광주지역 유통·판매 소고기에서 분리된 병원성대장균의 항생제 내성 및 유전적 특성조사

이민규,이향희,정혜진,조선주,정소향,서유진,조배식,정재근,서정미 한국식품위생안전성학회 2021 한국식품위생안전성학회지 Vol.36 No.2

본 연구는 광주광역시에 유통·판매되고 있는 소고기를 대상으로 식중독 발생 비율이 높은 병원성대장균의 검출 여부와 분리된 균주의 항생제 내성 및 유전적 특성을 조사 하였다. 전체 335건의 소고기 중 82건에서 병원성대장균이 검출(24.4%)되었고 102개의 다양한 균주를 분리하였다. 분리균주의 병원성 유전자를 토대로 분류한 결과, EHEC가 66 균주로 가장 많았고 EHEC와 EPEC 등 2가지 유전자가 동시에 검출된 균주도 11균주가 있었다. 분리된 균주의 항생제 내성 시험결과, 30균주는 1가지 이상의 항생제에 대하여 내성을 보였다. 그 중 tetracycline에 내성을 보이는 균주가 27균주로 가장 많았고 그 외에 ampicillin, trimethoprim/ sulfamethoxazole, chloramphenicol 등의 순으로 많았다. 분리 된 균주의 혈청형 검사 결과, 혈청형은 O26, O91, O103, O104, ,O111, O113, O121, O128 및 O145로 확인되었다. 따라서 소고기의 조리 가공 시 교차오염이 발생하지 않도록 조리기구 등에 대한 위생적 관리와 충분한 조리 등의 식중독 예방을 위한 주의가 필요할 것으로 생각된다. This study aims at investigating occurrence of pathogenic Escherichia coli (E. coli) associated with high rate of food poisoning in beef samples collected from markets in Gwangju, and the antimicrobial resistance and genetic characterization of the isolated strains. Pathogenic E. coli was detected in 82 (24.4%) of 335 beef samples, and 102 strains were isolated. Of 102 strains, 66 were identified as enterohemorrhagic E. coli (EHEC) and 11 strains harbored both pathogenic genes of EHEC and EPEC. In antimicrobial susceptibility test, 30 strains were resistant to more than 1 antimicrobial. The most frequent antimicrobial resistance observed in the isolated E. coli was to tetracycline, followed by ampicillin, trimethoprim/sulfamethoxazole, and chloramphenicol. Serotyping of isolated E. coli identified serogroups as O26, O91, O103, O104, O111, O113, O121, O128 and O145. Therefore, we suggest that hygienic management of cooking utensils and sufficient cooking are needed so as not to cause cross-contamination when cooking beef.

전자빔 용접을 위한 심트레킹 영상처리 기술 개발

조대원,김륜한,이광현,서정,최광덕 대한용접·접합학회 2021 대한용접학회 특별강연 및 학술발표대회 개요집 Vol.2021 No.11

본 연구는 전자빔 용접에서 수행하는 영상처리 기술에 관련된 내용으로 실시간 추적하는 용접선 추적 기술 개발을 수행하였다. 대기 중 용접에서 활용하는 카메라 이미지와는 달리 전자빔 용접은 진공 챔버에서 용접을 수행하기 때문에 본 연구에서는 SEM 이미지를 활용한 영상처리 기술을 개발하였다. 특히 SEM 이미지는 이진화된 graylevel의 밝기 특성을 보이며 용접중 왜란이 발생하므로 이를 해결하기 위한 알고리즘을 개발하였으며 추적 위치를 좌표값 혹은 벡터 성분으로 구분하여 2축 제어에 활용 가능하도록 하였다.

위장관의 원발성 B 세포 악성 림프종의 재분류와 bcl-2, cyclin D1, bcl-6 및 p53 발현의 의미

서정균,김태원,김병수,조은택,박찬국,김만우,이미자,전호종 조선대학교 2001 The Medical Journal of Chosun University Vol.26 No.2

Background and Objectives : In recent years, the REAL (Revised European American Lymphoma) classification provided a new category of MALT (mucosa-associated lymphoid tissue) lymphoma and mantle cell lymphoma in B cell lymphomas. We have analyzed the expression of bcl-2, cyclin D1, bcl-6 and p53 and correlated with the subtypes and histologic grade of primary gastrointestinal B cell lymphoma. Also we investigated the usefulness of immunophenotypic features in diagnosis of low grade B cell lymphoma. Materials and Methods : Twenty-two cases of primary gastrointestinal B cell lymphoma were recategorized in low grade MALT lymphoma, low/high grade MALT lymphoma, high grade MALT lymphoma, and diffuse large cell lymphoma according to the morphological findings. We investigated the expression of bcl-2, cyclin D1, bcl-6 and p53 by immunohistochemical method. Results : The bcl-2 protein expression was higher in the low grade MALT lymphoma than in the high grade lymphoma. The cyclin D1 protein expression was negative in all cases. The expression of bcl-6 and p53 protein was negative in all low grade MALT lymphoma. Conclusion : The results suggest that we can differentiate the low grade lymphoma from the high grade lymphoma by immunohistochemical staining for bcl-2, bcl-6, and p53 protien.

조해진 ( Hae Jin Jo ),장택균 ( Taek Gyun Jang ),최종하 ( Jong Ha Choi ),서정기 ( Jung Kee Suh ),전치완 ( Chi Wan Jeon ),김영호 ( Young Ho Kim ),이상학 ( Sang Hak Lee ) 한국공업화학회 2011 응용화학 Vol.15 No.1

A chemiluminescent method with silver nanoparticles for determination of L-alanine has been presented. The chemilumiscence intensity was further enhanced by silver nanoparticles in the luminol system by its catalytic role. The silver nanoparticles enhanced chemiluminescent method is applicable for the determination of an amino acid such as alanine. When alanine was introduced to the luminol system with silver nanoparticles, chemiluminescence intensity was reduced with the concentration of the added alanine. The effects of pH, concentrations of luminol, hydrogen peroxide and silver nanoparticles on the chemiluminescence intensity were investigated. The calibration curve for L-alanine was linear over the range from 6.60×10(-8) M to 4.00×10(-7) M, coefficient of correlation was 0.996 and detection limit was 3.5×10(-9) M under the optimal conditions of 4.0×10(-3) M, 4.0×10(-2) M, 4.0×10(-4) M, 12.8 for the concentration of luminol, H2O2, silver nanoparticles and pH, respectively.
