Introduction: All work of dental hygienists in Korea is to be carried out under the supervision of a dentist, but the main tasks of dental hygienists are systematic and sufficiently trained within the college curriculum. The purpose of this study was to compare the curriculum between the Department of Dental Hygiene and the Department of Dentistry to provide a basis for legal revision of the dental hygienist's unique work. Methods: The curriculum was acquired from the homepage of the Department of Dental Hygiene and Dentistry. The curriculum in 23 of 28 dental hygiene schools and 6 of 11 dental schools was identified on the homepage. The swere classified based on the scope of dental hygienist work. Results: The Department of Dentistry has more than twice the number of credits and subjects compared to the Department of Dental Hygiene, and the top subjects belong to the treatment and rehabilitation of dental diseases. However, in the field of preventive dentistry, which is a unique work of dental hygienists, the Department of Dental Hygiene has a score of 9.3 times higher than that of dentistry. In the public oral health field, the oral health education field, and the dental management field, dental hygienists scored twice as high as dentists. Conclusion: Since dental hygienists are receiving more education than dentists in the areas of preventive dentistry, public oral health, oral health education, and dental management, which are unique tasks, it is suggested that the work can be performed independently without supervision of the dentist.

Objective: The purpose of this study was to analyze the Cone-beam computed tomograghy(CBCT) scan of endodontically treated maxillary first molars and investigate how second mesiobuccal (MB2) canal is treated, how the prognosis of mesiobuccal (MB) root is different compared to other roots and the prognosis factor on apical periodontitis. Methods: Subjects were endodontically treated maxillary first molars whose were collected from CBCT scans taken from January 2018 until December 2019. A total of 525 maxillary first molars were analyzed by an endodontist to determine the presence of the MB2 canal, the quality of the root canal filling, and the presence of apical periodontitis. The chi square test and Fisher's exact test was used to examine the relationship between each variable. Results: MB2 canals were found in 46.3%, of which 76.5% were not treated. The more main canal of mesiobuccal root (MB1 canal) was well filled, the more significantly MB2 canal was well filled (p<0.001). The apical periodontitis of MB root was not related to the filling quality of MB1 canal (p=0.370) and was related to the filling quality of MB2 canal (p=0.004). The apical periodontitis of MB root was related to the quality of canal filling of MB2 canal and the apical periodontitis of DB and P root. Conclusions: It was found that the majority of MB2 canals were not treated. The apical periodontitis of MB root was analyzed to be related to the quality of canal filling of MB2 canal. The apical lesion of the MB root was not correlated with the treatment of the MB1 canal, but it was significantly related to the quality of filling of MB2 canal.

Introduction: The legal duties of Korean dental hygienists are different from the actual tasks. These factors cause dental hygienists to experience work stress. Therefore, it is necessary to investigate what tasks the dental hygienist expects to perform. Methods: This study examined the perception of dental hygienists' work on 158 prospective graduates of the 3rd-year and 4th-year course of dental hygiene. The questionnaire about the dental hygienist's duties was prepared based on the job description of dental hygienists by the Korea Health Personnel Licensing Examination Institute. Results: More than 84% said that all of the work in the second job description was possible as dental hygienists. subjects responded that the following items were not dental hygienists' duties: treatment plan based on medical history and dental history, treatment plan based on an intraoral and extraoral examination, treatment plan based on the results of teeth and periodontal examination, analysis of oral health data in community, planning of oral health promotion in community, planing of water fluoridation, reading of radiography, root planing, physical treatment on head and neck, using an ultrasonic device on head and neck, dealing with laser devices, making a temporary crown, suture and stitch-out, and intramuscular injection. Conclusions: Most graduates of dental hygiene departments have recognized that the tasks described in the second job description are dental hygienists' work; therefore, it is necessary to improve the gap between expected work and legal work.

증례보고 : 발달장애인 구강보건교육사업 전후 비교

황수정,김민지,송은주,Hwang, Soo-Jeong,Kim, Min-Ji,Song, Eun-Joo 대한치과위생학회한국치위생과학회 2020 대한치위생과학회지 Vol.3 No.1

A total of nine oral health educators for 17 persons with developmental disabilities conducted oral health education once a week for four weeks. The oral health educators provided oral health knowledge education and individual toothbrushing teachings. The developmentally disabled people in their 20s and 30s conducted oral health education without a guardian. Ten people who completed all the four pieces of training had no significant improvement in the toothbrushing method and the recommended number of toothbrushing sessions a day, as well as a lack of growth in oral health knowledge. However, 58.8% of the individuals expressed satisfaction with the oral health education program, whereas, 52.9% expressed the desire for a re-education. Although the ratio of teachers to students was 1:2, and the oral health education conducted four times, it was insufficient to promote a successful oral health behavior or knowledge for people with developmental disabilities. Therefore, as a suggestion, oral health education for people with developmental disabilities ought to proceed with their guardians to promote the success of the training.

자반고등어에서 histamine 분해능을 가진 세균의 분리 동정

황수정,김영만,Hwang Su-Jung,Kim Young-Man 한국생명과학회 2005 생명과학회지 Vol.15 No.5

Histamine은 적색육 어류의 histidine이 어육 중의 Morganella morganii, Hafnia alvei 및 Klebsiella pneumoniae와 같은 부패세균에 의해 탈탄산 되어 초기에 형성되는 것으로 allergy성 식중독을 일으킬 수 있다. 이는 적색육 어류인 고등어의 선도저하 시에 많이 생성된다. 그리고 부패 후기에는 histamine을 분해하는 세균도 존재하는 것으로 알려져 있다. 그러므로, histamine 식중독의 잠재력을 지닌 자반고등어로 인한 식중독 사고 예방과 그 위생 대책을 수립하는데 필요한 자료를 얻고자 자반고등어에서 histamine 분해능을 가진 균을 분리, 동정하였다. 시료는 대형마트에서 시판되는 상태로 구입하였다. 질소원과 탄소원으로써 histamine만을 첨가한 제한배지를 사용하여 histamine 분해능을 가진 균을 분리하였다. 그리고 Cram staining, oxidase, catalase, citrate, TSI test, $H_{2}S$ reaction 및 indole 생성 등의 기본적인 생화학적 동정시험을 거쳐 10종의 시험균주를 선택하였다. 이 균주들을 16SrRNA gene 염기서열 비교에 의한 계통발생학적 분석을 이용하여 동정 하였다. 그 결과, Pseudomonas putida strain RA2, Halomonas marina, Uncultured Arctic sea ice bacterium clone ARKXV1/2-136, Halomonas venusta, Psychrobacter sp. HS5323, Pseudemonas putida KT2440, Rhodococcus erythropolis, Klebsiella terrigena (Raoultella terrigena), Alteromonadaceae bacterium T1, Shewanella massilia의 10종이 모두 동정 되 었으며, 각각 $100\%,{\;}100\%,{\;}99\%,{\;}99\%,{\;}99\%,{\;}99\%,{\;}100\%,{\;}95\%,{\;}99\%,{\;}100\%$의 상동성을 보였다. Histamine분해능의 존재를 탁도측정법과 효소법에 의해 확인한 결과, 분리된 10종 모두의 histamine 분해능이 재확인 되었고, 그 중 Shewanella massilia가 최대의 histamine 분해능을 보이는 것으로 확인되었다. 이 결과로 자반고등어 시판 제품에는 다수의 histamine 분해 세균이 존재하는 것을 확인할 수 있었으며, 이 세균을 활용한다면 식품 내 존재하는 histamine을 효과적으로 분해할 수 있을 것이라 예상된다. Histamine can be produced at early spoilage stage through decarboxylation of histidine in red-flesh fish by Proteus morganii, Hafnia alvei or Klebsiella pneumoniae. Allergic food poisoning is resulted from the histamine produced when the freshness of Mackerel degrades. Conversely it has been reported that there are bacteria which decompose histamine at the later stage. We isolated histamine decomposers from salted mackerel and studied the characteristics to help establish hygienic measure to prevent outbreak of salted mackerel food poisoning. All the samples were purchased through local supermarket. Histamine decomposers were isolated using restriction medium using histamine 10 species were selected. Identification of these isolates were carried out by the comparison of 16S rDNA partial sequence; as a result, we identified Pseudomonas putida strain RA2 and Halomonas marina, Uncultured Arctic sea ice bacterium clone ARKXV1/2-136, Halomonas venusta, Psychrobacter sp. HS5323, Pseudomonas putida KT2440, Rhodococcus erythropolis, Klebsiella terrigena (Raoultella terrigena), Alteromonadaceae bacterium T1, Shewanella massilia with homology of $100\%,{\;}100\%,{\;}99\%,{\;}99\%,{\;}99\%,{\;}99\%,{\;}100\%,{\;}95\%,{\;}99\%,{\;}and{\;}100\%$respectively. Turbidometry determination method and enzymic method were employed to determine the ability of histamine decomposition. Among those species Shewanella massilia showed the highest in ability of histamine decomposition. From these results we confirmed various histamine decomposer were present in salted mackerel product in the market.

Jebyunghwsipjeol describes historical agony of righteous scholars of integrity. He described it honestly and lyrically. Their behaviors promoted Maechon's righteous spirit. Thus, he expressed righteous spirit, loyalty, simplicity and persistence of persons of integrity in Jebyunghwsipjeol . He showed his patriotic intention based on behaviors of the ten people. Honest and righteous spirit in his poetry has a significant meaning for future relationships between China and Korea., and this study will be bases for studies on integrity of intellectuals in Korea and China.

구례 시단의 지역정서 표출양상

황수정 ( Su Jeong Hwang ) 한국고시가문학회 2010 한국시가문화연구 Vol.0 No.25

본고는 구례 시단의 지역정서 표출양상을 고찰한 것이다. 황매천과 구례 시인들의 작품 중에서 구례라는 지역의 특수성이 드러난 작품에 초점을 두었다. 이처럼 지역성이 부각된 시는 지역의 독특한 정서와 미감을 알 수 있다. 아울러 이들 시를 통해 역동적이면서도 사실적인 미감을 조명할 수 있다. 특히 구례의 명소 중에서 연곡사와 용호정, 그리고 오봉산은 그들의 역사와 멋이 담긴 대표적인 장소라 할 수 있다. 따라서 이 세 곳에 대해 읊은 시를 중심으로 고찰하였다. 첫째, 연곡사에 대한 시에서는 주로 강개한 정서를 표출하였다. 아름다운 경관을 갖춘 연곡사에서 있었던 역사적 상흔은 구례인들에게 비장한 마음가짐과 강개한 기상을 이어갈 수 있게 하였다. 이러한 되새김은 시간이 지날수록 후손들에게 강한 정신적 유산으로 계승됨을 그렸다. 둘째, 용호정에 대한 시에서는 애상적인 정조가 드러났다. 용호정에서는 주로 유민의 한을 토로하였다. 이는 개인적인 이별의 정조를 넘어선 나라 잃은 백성의 슬픔을 표출한 것이다. 셋째, 오봉산에 대한 시는 낭만성을 부각시켰다. 오봉산의 신비한 모습을 통해 낭만적인 정감을 드러냈다. 이는 현재의 어려움을 소박한 멋과 풍류로 안위하고자 한 것이다. 또한 오늘의 난관을 극복하고, 내일을 여는 힘을 얻고자 한 것이다. 이처럼 황매천과 구례 시인들은 지역의 역사와 멋을 기리며 진솔한 정감을 담아냈다. 이러한 바탕 위에 지역의 독특한 정서를 표출하였다. 때로는 강개하게 때로는 애상적으로, 그리고 때로는 낭만적으로 구례인의 서정을 노래한 것이다. This study examines expression of local emotion centering on poetic works by Maechon Hwang Hyeon and poets in Gurye that show regional peculiarity of Gurye. We can identify peculiar emotion and realistic aesthetics of each region through the poetry that highlights locality. In addition, we can illuminate dynamic and realistic aesthetics through the poetry. Yeongok Temple, Yongho Pavilion and Mt. Obong are representative places with history and elegant tastes of Gurye people. First, poetry on Yeongok Temple expresses righteous emotion. Historical traumas in the temple with beautiful landscapes led Gurye people to have righteous spirit and brave mind. The poetry describes such reflection handed down to descendants as powerful mental heritage as time lapses. Second, the poetry on Yongho Pavilion shows sad feeling. It expresses grief of the migrants. It indicates sorrow of the people who lost their nation beyond sorrow of personal separation. Third, the poetry on Mt. Obong highlights romantism. It shows romantic senses through mysterious appearance of the mountain. It was designed to soothe present difficulties with elegant tastes and art and music. And it was to overcome present impasse and gain power to open tomorrow. Thus, Hwang Maechon and poets in Gurye longed for local history and elegance and described true and honest feeling, on which they expressed their peculiar emotion. It is righteous and romantic description of Gurye people`s emotion.

금창강(金滄江)과 황매천(黃梅泉)그 정운(停雲)의 시(詩)

황수정 ( Su Jeong Hwang ) 한국고시가문학회 2011 한국시가문화연구 Vol.0 No.28

본고는 滄江金澤榮(1850~1927)과 梅泉黃玹(1855~1910)의 시적 교류에 대한 분석이다. 김창강과 황매천, 두 사람 간 停雲의 시를 고찰한 것이다. 停雲은 멀리 있는 친한 벗을 생각할 때 쓰는 말이다. 격변의 시기에 한문학의 전통을 유지하며 그 빛을 발하게 했던 두 인물의 시적 교류에 초점을 두었다. 이들은 뛰어난 능력으로 인해 일찍이 촉망받았다. 그러나 자신들이 원했던 바를 마음껏 펼치면서 살았다고는 볼 수 없다. 단지 시대적인 고충과 이를 극복하기 위한 나름의 방식을 부단히 찾으면서 살았다고 할 수 있다. 이에 대한 교감을 시적 교류를 통해서 알 수 있었다. 또한 두 사람만의 특별한 정감과 애환을 읽을 수 있었다. 이로써 두 사람의 개인적인 관계를 넘어서 당대 지식인의 정신적 기저와 위기의식, 그리고 그에 따른 대응양상의 저변을 파악할 수 있다. 이 연구를 통해 창강과 매천의 만남이 갖는 의미를 재조명 할 수 있었다. 첫째, 두 사람의 문학적 소통은 격려와 신뢰가 기반이 되었다. 창강과 매천은 서로의 능력을 인정하면서 신뢰를 쌓았다. 이들은 젊은 날 입신에 대한 기대와 실망을 겪은 인물이다. 따라서 이들이 보여준 정신적 기저에는 난세를 극복하고 적응해야 할 응전력이 요구되었다. 지식인으로서의 당대 삶에 대한 문제의식과 문학적 어울림은 시대를 함께 공감하며 문학적 기량을 나눌 수 있는 계기가 된 것이다. 이러한 두 사람의 만남은 문학에 대한 격려와 신뢰를 기반으로 하고 있다. 이로써 창강과 매천의 문학적 소통이 이루어질 수 있었던 것이다. 둘째, 萬里밖 정운에 대한 동경과 그리움을 표출하였다. 창강은 격변기 속에서 중국으로 망명의 길을 택하였다. 그러나 매천은 집안 사정으로 함께 가지 못하였다. 매천은 벗에 대한 그리움 속에 한없는 동경을 그려냈다. 문학적 이상을 펼치기 위한 창강의 결단을 높이 산 것이다. 이는 개인적인 안녕과 변화에 대한 추구를 넘어선 시대 적응능력에 대한 찬탄이기도 했다. 그 밑바탕에는 창강의 문학적 능력과 활동에 대한 기대와 격려를 담고 있다. 창강은 마음속에 가득한 그리움의 공간을 벗에게 보내는 시에 담아냈다. 그래서 이국에서의 고뇌와 그리움을 벗인 매천을 통해 위로받고자 한 것이다. 당시 두 사람이 나눈 시에는 시국의 혼란을 바탕으로 한 고뇌와 그리움을 실었다고 볼수 있다. 셋째, 벗에 대한 추억과 추모의 정서가 표출되었다. 창강과 매천에게 있어 벗에 대한 추억은 지난 과거에 대한 회상과 함께 미래 전망을 가능하게 하였다. 또한 이들의 관계 형성에 있어 진정한 의미를 반추할 수 있었다. 지식인으로서 한 시대를 살면서 극복해야 했던 과제와 감당해야 했던 고난이 표출되었다. 이로써 각기 다른 두 사람의 시대적 대응양상의 저변을 파악할 수 있었다. 매천이 추억한 창강의 모습은 벗의 능력에 대한 강한 믿음이 바탕이 되었다. 따라서 벗의 미래에 대한 전망과 기대로 이어졌다. 창강은 매천의 애석한 죽음에 대한 통절한 슬픔과 지음을 잃은 고통을 표출하였다. 이는 고국에 대한 애끓는 절망의 토로인 것이다. This study aims to analyse poetic exchanges between Changgang Kim Taek-young (1850~1927) and Maechon Hwang Hyun(1855~1910). That is, it looked at poetry on Jeongun(停雲). Jeongun(停雲) indicates close friends who are far away. This study focused on poetic exchanges of the two persons who were engaged in development of Chinese literature while maintaining its tradition in the period of a sudden change. They were promising literary persons because of their outstanding ability. However, it is believed that they did not realize as much as what they dreamed. They attempted to find out their own methods to overcome hardship of that time. Their delicate responses were expressed through poetic exchanges, through which special senses, joys and sorrow, spiritual ground, sense of crisis, and responses of the intellectuals of those days were read. This study was able to reconsider the meaning Changgang met Maechon in this process. First, their friendship was based on literary communication and trust. Changgang and Maechon built up trust, recognizing ability of each other. They could not show their vigor and enthusiasm through national examinations because they were from families of low class. Thus, they had expectation and despair of success in life simultaneously when they were young. Therefore, their spiritual base needed ability to overcome and respond to turbulent days. Their meeting encouraged them to pursue literature and trust, which was achieved through literary communication. Second, their poetry expressed missing towards a friend who was far away. Changgang selected an exile during turbulent days. However, Maechon did not because of family condition. Maechon missed and longed for a close friend as he valued Changgang`s decision to realize his literary ideal highly. It was an admiration for his ability to adjust the time beyond a pursuit for personal wellbeing and changes. It contains expectation of Changgang`s literary ability and encouragement of him. Changgang described his missing in poems to him as he intended to be consoled by Maechon, a friend of agony and missing. The poetry both exchanged at that time had agony and missing based on turbulence of those days. Third, his poetry expressed memories of a friend. Maechon`s memories to Changgang contained the future prospect and the past reflections, through which a true meaning in their relationship was reconsidered. It also had hardship they had to face as intellectuals. The base of their response to the time was expressed. Maechon had memories of Changgang based on strong trust of his ability, leading to inspiration and expectation. Changgang expressed sorrow and pain of losing a friend, exposing his despair of the nation through the poetry.

The physical properties of dough with different levels (2, 4, 6, and 8%) of bamboo leaf powder were inverstigated. The bamboo leaf powder had a moisture content of 5.15%, a crude protein content of 10.48%, a crude fat content of 5.21%, a crude fiber content of 22.74%, and a crude ash content of 17.63%. The following parameters showed significant differences with the increase in the amount of bamboo leaf powder added. The gelatinization degree measured by a rapid visco-analyzer increased with the increase in the powder amount added. In the values of the farinogram parameter for dough consistency, the elasticity of the dough increased with the increase in the powder amount added. The alveogram values showed a similar tendency as those of the farinogram in terms of elasticity, absorption rate, absorption time and stability. In the rheofermentometer analysis, the volume decreased with the increase in the powder amount added, but no significant difference was found at up to 4% powder amount addition, suggesting that the about 2% and up to 4% powder amount addition is moderate.
