문철현(Cheol-Hyun Moon),이동근(Dong-Gun Lee) 대한치과의사협회 2007 대한치과의사협회지 Vol.45 No.4

저자들은 modified Nance appliance를 이용하여 환자의 협조에 의존하지 않고 매복된 치아의 교정적인 맹출을 시행하여 양호한 결과를 얻을 수 있었다. 특히 Moon’s appliance를 이용하여 동일 악궁 내에서 약하고 정교한 지속적인 힘을 적용 할 수 있었으며, 힘의 방향을 바꾸기 위한 과정에서 장치 전체를 철거해야 하는 번거로움을 해소 할 수 있었다. Traction of impacted tooth often requires patient compliance to place elastics to surgically exposed impacted tooth. It can be very difficult and time-consuming. The aim of this article was to describe an impacted tooth tractor, Moon s appliance, which was modified from the Nance holding arch appliance. Moon s appliance eliminates patient compliance and generates a light continuous force. We achieved the desired treatment results for impacted tooth using this appliance. This new fixed appliance can be a reasonable alternative to conventional appliances.

The impact of blowflies on pig cadaver decomposition on Yeongdo Island, Busan, South Korea

Park Sang‐Hyun,Baek Seung‐Ho,Moon Tae‐Young 한국곤충학회 2021 Entomological Research Vol.51 No.11

The decomposition process is an important factor in forensics, and flies play a crucial role in the decomposition of animals and humans. However, there remains limited information on the effect of flies that attend death scenes. This study assesses the effect of the presence or absence of blowflies on the rate and process of cadaver decomposition in the spring, summer, and autumn from 2016 to 2020 on Yeongdo Island, Busan, South Korea. Nine blowfly species belonging to four genera in two subfamilies were sampled. The blowflies that approached the cadavers differed between seasons, but Chrysomya pinguis (Walker) was the dominant species regardless of the season. Blowfly presence on cadavers significantly affected the duration of the decomposition stage and the pattern of weight loss in nearly all scenarios. With the presence of blowflies, the decomposition rate was four times faster in spring, three times faster in summer, and nine times faster in autumn. These results show that the presence or absence of blowflies is an essential factor in the decomposition process of cadavers. Therefore, it should be taken into account when estimating postmortem intervals in medicolegal forensic entomology.

Consistency of seasonal patterns of insect succession on pig cadavers at Yeongdo Island in Busan, Korea

Park Sang‐Hyun,Moon Tae‐Young 한국곤충학회 2021 Entomological Research Vol.51 No.1

Cadaver insects cause dead bodies to break down in ecological processes. Still, the knowledge has been accumulated slowly about the structure and role of the insect assemblages attending to death scenes. This study analysed the successional patterns of insects on pig cadavers in the spring, summer, and autumn from 2016 to 2019 at Yeongdo Island, Busan, South Korea. A sum of 71 insect species belonging to four orders and 21 families were sampled. Predominant insects were largely Diptera and Coleoptera. The majority of the flies were the calliphorids as Chrysomya pinguis (Walker) and Lucilia porphyrina (Walker). The most common beetles were Creophilus maxillosus (L.), Omosita japonica (Reitter), and Staphylinidae sp. regardless of seasons. Occurrence matrices were made from the successional patterns of insect species during 42 sampling intervals in the spring, 38 sampling intervals in the summer, and 26 sampling intervals in the autumn. Permutation analyses of the occurrence matrices showed that the patterns of succession were similar between spring 2016 and 2017 (P = 0.019), between summer 2016 and 2017 (P = 0.003), and between autumn 2016 and 2019 (P = 0.002). The result shows that there are clear patterns in succession between seasons, and provides the reference data to presume the death time, at least in the southeast part of South Korea.

Forensic implication of cadaveric behaviors of the Japanese pavement ant (Tetramorium tsushimae Emery) attending to rabbit cadavers

Park Sang‐Hyun,Moon Tae‐Young 한국곤충학회 2020 Entomological Research Vol.50 No.4

It is noticed by some researchers that ants may cause some forensic confusion in understanding death scenes. In the aspect of relationship between the ant-animal decomposition, we observed the behavior of ants congregating on dead animals. Amongst various species of ants visiting dead rabbits, Tetramorium tsushimae Emery was noticeable in producing scratched scars, mounds, and nests around dead rabbits and covering them with soils. The behaviors are likely to interfere or to disturb the usual process of decomposition succession lead by maggots. We discussed that a series of cadaveric behaviors of T. tsushimae may be used as a potential forensic hint not to misunderstand death scenes disturbed by the species.

정현욱,채제욱,강미라,양정채,문치숙,기현균,장현하,오원섭,김기현,백경란,이남용,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

목적 : 국내에서 발열을 동반한 호중구감소증이 있는 악성 종양환자에게 경험적 항생제로 베타락탐계 항생제와 아미노배당체의 병합요법의 사용이 일반적이다. Cefepime은 광범위 항균 작용을 가지고 있어, 그람 음성균 뿐만 아니라 그람 양성균에 대해서도 우수한 효과를 나타낸다. 재료 및 방법: 발열을 동반한 호중구감소증이 있는 악성 종양환자를 대상으로 무작위, 공개, 비교 연구를 시행하였다. 대상 환자를 무작위로 cefepime 단독요법군과 ceftazidime 및 tobramycin 병합요법군으로 나누어 투여하고 각각의 임상적 효능과 안전성을 비교하였다. 구강및 인후 점막염이 있는 환자에서 분리된 녹색 연쇄알 구균에 대한 항생제 내성 정도를 조사하였다. 결과 : 대상환자 89명 중 CA 투여군이 48예(53.9%), CT 투여군이 41예(46.1%)이었다. 발열의 유형별로 MDI는 18예(20.2%), CDI는 9예(10.1%), UF는 62예(69.7%)로 두 군 간에 차이가 없었다. CA 투여군과 CT 투여군의 임상적 호전률은 시험약 투여 후 2-4일째 각각 91.7%, 85.4% (P=0.31), 치료 종료 시 각각 91.7%, 100% (P=0.15)로 두 군간에 유의한 차이가 없었다. 치료 종료 시 CA 투여군과 CT 투여군의 세균학적 소실률은 모두 100%로 두 군간의 유의한 차이가 없었다(P=0.78). 점막염이 있는 환자로부터 녹색 연쇄알 구균이 분리된 경우는 25예(28.1%)이었으며, 분리된 녹색 연쇄알 구균은 penicillin, ceftriaxone, cefepime, vancomycin에 모두 감수성을 보였다. 약제 관련 이상 반응의 발생 빈도도 두 군간에 유의한 차이가 없었다. 결론 : 발열을 동반한 호중구감소증이 있는 악성 종양환자의 경험적 항생제로서 cefepime 단독요법은 ceftazidime 및 아미노배당체의 병합요법만큼 효과적이고 안전하였다. Background : Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. Materials and Methods : To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. Results : A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC_(90) 0.12 ㎍/mL), cefepime (1 ㎍/mL), and vancomycin (0.12 ㎍/mL). Conclusion : Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.

Distribution and mitochondrial DNA tracing of the invasive Argentine ants (Linepithema humile) in South Korea

Park Sang‐Hyun,Ha Young‐Ho,Kim Dong Eon,Kim Chang‐Jun,Choi Moon Bo 한국곤충학회 2021 Entomological Research Vol.51 No.3

Argentine ants (Linepithema humile) are one of the world’s most invasive species and were first reported in South Korea, near Busan Port in 2019. The distribution of their initial spread was investigated here from April to July 2020. In the invasion area, numerous nests and individuals were identified, indicating that they had settled and successfully invaded the habitat. To track the invasion of the Argentine ants we conducted haplotype analysis using COI, COII, and Cytb sequences of their mitochondrial DNA. The invasive ants had the same mitochondrial haplotype (H3) as Argentine ants from America (Chile, Ecuador, Bermuda) and East Asia (Japan). When comparing the import trade volumes at Busan port with the Argentine ant haplotypes from other countries, it was determined that the invasive ants may have originated from the United States or Japan. Numerous ecological and economic impacts due to their invasion and spread in other countries has previously been reported. Therefore, prompt control measures for the Argentine ants found at Busan port, at this relatively early stage of settlement, is required.

양호교사의 역할수행에 관한 조사연구

문희자,박신애,강현숙,고정은 慶熙大學校 1985 論文集 Vol.14 No.-

It is the ultimate purpose of school health management to protect, maintain, and prormote the students' health and to help for them to form a wholesome habit of health. To do this, school nurse is an actual professional personnel of school health management in our country. therefore, role performance of a school nurse is directly related to the quality of school health planning, we think. With this belief, this study intends to revise, supplement Rustia model for school health promotion and develop in into a suitable model for our actual situation. In so doing, based on Rustia model, we had surveyed the actual situation of a school nurse's role performance by making 77 school nurses in Boys' and Girls' Middle and High Schools in Seoul as the scope of this research for a period of two months beginning on September 1, 1984. The results were analyzed by employing percentage and mean value. The results of the investigation are as follows: 1. General Characteristics of the school nurses and schools. (1) The average age of the surveyed school nurses is 31.64± 6.6 years old. 81.6% of them was proved to have acquired academic background above Colleges and Graduate Schools; 74% were married; 61% were religious persons. And the average on-duty term was 6.42±5.03 years. 66.2% of them employed in the hospitals before this present job and 31.2% have worked at school as school nurses immediately after their graduation. In college, most of them (81.8%) went through a course of study for the teaching profession and only 9.1% of the taught other courses of study. (2) The majority of the surveyed schools (51.9%) were public schools and 62.3% of them were middle Schools. The average number of students in the school was 2628.52;that of school pesonnel was 66.17±9.7;that of classes was 39.68±12.0. 2. Role performance for primary prevention. (1) Among the serveyed schools, 83.1% of them performed epidemiological analysis of health problem for the promotion of health. As for health planning among health management plan, all of them put it in force, however, only 35% of them participated in preparation of the budget to achieve it. As to the evaluation program, 64.9% of them carry out it into operation and in case of being carried out once in a year marked the most frequency of enforcement as 32.4%. On guidance and support related to health planning, 42.9% of them held a staff meeting; of which 53.2% were school nurse-teacher meeting; 28.6%, school nurse-parent meeting. (2) To protect the students and school personnel from danger and injury, 67.5% of them participated in alleviating health problems-that is, the maintenance of health standard and safety within school, and inserting the means of settling those problems into curriculum and management of school events. Especially, only 14.3% administered school lighting and 35.1% observed safety standards of desks and chairs in class. Consequently, the result of this survey revealed that there is much to be desired in the administration for the maintenance of health standard and safety. As for pervention of infectious disease, the following were implemented; a) disinfection of toilets (92.2%); b) control of drinking water (75.5%); c) purification of sewage and garbage incineration (74%). What is pecular is that 71.4% of them have controlled vaccination but enforcement rate shows lack of enthusiasm when viewed from the kinds of vaccination: Typhoid fever (51.9%), cholera (41.6%) hepatitis (9.0%), encephalitis (23.4%) and that one or two sorts of vaccination were treated. As for the technical improvement of personnels who handled health problems, all of them put it in practice, and for prevention program and use of health resources, 87.5% participated in it. 3. Role performance for secondary prevention (1) 92.2% of them carried out screening tests of a physical assessment for an early detect on health problem and 24.7% did a screening tests which made a part of students its object after the first screening tests. A selection and check-up of measurement tool during a developmental evaluation was taken effect by 98.7% and a preliminary education on the persons who administered that examination and determine to select a place for it by 100%. Of discrimination and screening tests, various kinds of examination for finding disease was detected effectively by 98.7% and of this operation nothing could be come into force more than a check-up of parasites and urine with 97.4%. As to the methods explaning danger of health and safety, the case to be offered school personnels information in a staff meeting marked 96.1% and the one to offer students information in the case of generating such danger as infectious diseases was 100% (2) Control of health problem to be required regular treatment for taking a proper measure on that problem at an earlier time was carried into effect by 93.5%. 98.7% of them imposed a role of communication and intervention of offering and observation method for finding health problem and encourging this method to teacher in charge. All of them executed emergency care, School-nurses helped 33 persons a day on the average, and 89.6% of them did for students to get through a serious crisis. (3) In order to prevent complication and an disable, 83.1% of them carried out a continuous follow-up care of the students who were discharged from the hospitals. 4. Role performance for tertiary prevention (1) In order to care and treat the students who needed their rehabilitation and adaptation for activities of daily living, 89.6% of them performed reeducation after reevaluate their health status, 94.8% performed a role on motivation, 85.7% put in effect a continuous control of the students who needed rehabilitation and correction, and 15.6% did counselling for taking a measure to meet the situation of the disabled. 5. Role performance for health education. Unifying health education from the view points of the first, secondary and tertiary prevention against diseases, we surveyed the content, method, objectives of health education which is now in effect and should be emphasized in the future. Upon this study, we came to conclude as the following; as to the content of health education which is now is effect, prevention of infectious diseases has an absolute majority of all contents as 98.7%, and prevention against parasites, personal hygiene and oral hygiene second place. as 97.4% But education on prevention of venereal diseases shows inactiveness as 42.9%. On the contents to be emphasized, mental health (42.9%), sex education (40.3%) were enumerated but nobody stated about prevention of infectious diseases. As a method practising health education, all of them used that of counselling, and as an indirect education utilizing media, it comes printed matters (96.1%), poster (83.1%), interclass broadcasting casting (75.35) in that order. And the case of regular class on health education marked 23.4%, of the object of health education, 98.7% made students its object; 87.0% school personnels; 51.9% parents of students.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

Windows Environment에서의 CAI Authoring System 설계

문현주,송후봉 崇實大學校 生産技術硏究所 1994 論文集 Vol.24 No.-

Authoring systems are powerful tool to develop Computer-Assisted Instruction(CAI) programs. It is possible to author CAI programs easily for non-expert who don't have any knowledges of programming language, as compared with other authoring tools. The study of authoring system has been studied in America, Japan, France, and so on since 1960, but in Korea it is the way to begin. This thesis investigates the conventional authoring systems, and designs a new authoring system based on the Windows environment. This system provides us with the simplicity of use and the compatibility based on the unified user interface environment.
