김흥철,정승태,Brett W. COLLIER,이희춘,Terry A. KLEIN 한국곤충학회 2007 Entomological Research Vol.37 No.3

Adult mosquito surveillance was conducted during 2004 at 29 US military installations and training sites located in six provinces in the Republic of Korea. Adult mosquitoes were collected in New Jersey light traps and Magnet traps from 1 May through 15 October to determine threshold levels to initiate pesticideapplications and to identify malaria infection rates at selected army installations and training sites. A total of 89 206 adults (78 454 [87.9%] females and 10 752 [12.1%] males) comprising 20 species (including five members of the Anopheles Hyrcanus Group) and belonging to seven genera were collected. The most common species collected were members of Culex tritaeniorhynchus Giles (49.4%) and Anopheles sinensisWiedemann complex (39.1%), followed by Culex pipiens Coquillett (6.1%) and Aedes vexans nipponii (Theobald) (4.2%). Trap indices varied widely for species over their range, due in part to geographical distribution and degree of association with urban communities.

We report here on a case of a recurrent left anterior neck infection and focal left suppurative thyroiditis that were associated with a congenital pyriform sinus fistula (PSF) in an 18-year-old male. Acute suppurative thyroidits is a very rare clinical condition and it is usually caused by infection that's derived from infected perithyroidal tissue or a congenital internal fistula. The PSF can lead to recurrent episodes of neck inflammation and abscess, and it is the most common cause of acute suppurative thyroiditis in young man. In this current case, the CT scan showed an air-containing tract of a PSF from the left pyriform sinus to the left thyroid gland and the perithyroidal soft tissue. The CT scan also showed a neck inflammatory infiltration or abscess along the course of the sinus tract. The focal low density of the thyroid parenchyma was seen and this was suggestive of suppurative thyroiditis. Barium esophagography demonstrated the fistulous tract in the PSF. We performed laryngoscopy, and the internal opening of the pyriform sinus fistula was successfully cauterized with AgNO<SUB>3</SUB> and the post procedure course was fair. When an air-containing tract and a recurrent inflammatory infiltration or abscess are present at the left anterior neck with including the thyroid and perithyroidal soft tissue, a PSF should be strongly suspected. <B>(Ko</B><B></B><B>rean J Endocrine Surg 2008;8:206-209</B><B>)</B>

Historical review and surveillance of Japanese encephalitis, Republic of Korea, 2002–2004

김흥철,Michael J. TURELL,Monica L. O’'GUINN,John S. LEE,정성태,주영란,Terry A. KLEIN 한국곤충학회 2007 Entomological Research Vol.37 No.4

Japanese encephalitis virus (JEV), transmitted by culicine mosquitoes, is endemic throughout much of South-East Asia, extending to the Korean Peninsula. The zoonotic cycle is from large water birds to culicine mosquitoes, with swine as an amplifying host and man as an incidental host. Culex tritaeniorhynchus, the primary JEV vector in the Republic of Korea, populations peak in late August through to early September when most cases of Japanese encephalitis (JE) are reported. Cx. tritaeniorhynchus were observed near the Demilitarized Zone in each of the years that mosquitoes were assayed for JEV. Each year that vector mosquitoes were assayed for JEV, minimum field infection rates (number of JEV positive mosquites/1000Cx. tritaeniorhynchus assayed) ranged from 0.31 to 3.27. The epidemiology of JE has been recorded in Korea for more than half a century, from 1949 to 2005. During a major epidemic in 1949, there were 5616 cases and 2729 deaths reported, with levels persisting near epidemic levels of 1000 cases annually thereafter until 1969. Following the introduction and government mandated mass immunization in 1971, JE decreased dramatically. Since 1984, 0-6 cases of JE have been reported each year. However, continued evidence of mosquitoes positive for JEV indicates that JE continues to be a civilian and military health threat to immunocompromised persons in Korea, as well as non-immune US soldiers, civilians and their family members.

김흥철,정승태,Lisa L. O'BRIEN,Monica L. O'GUINN,Michael J. TURELL,이희춘,Terry A. KLEIN 한국곤충학회 2006 Entomological Research Vol.36 No.3

Surveillance of adult mosquitoes was conducted at 29 US military installations and training sites in six provinces in the Republic of Korea during 2003. Adult mosquitoes were collected in New Jersey light traps and dry ice-baited New Jersey light traps from 1 May to 15 October. Mosquito surveillance was conducted to determine threshold levels to initiate pesticide applications and identify malaria infection rates at selected army installations and training sites. A total of 42 024 adult mosquitoes (32 594 females [77.6%] and 9430 males [22. 4%]) comprising 14 species and Anopheles sinensis s.l. (a complex of five species), representing seven genera, were collected. The most common species were members of theAnopheles sinensis Wiedemann complex (54.9%), followed by Aedes vexans nipponii(Theobald) (19.0%), Culex pipiens Coquillett (14.3%) and Culex tritaeniorhynchusGiles (10.6%). Trap indices varied widely for species over their range, due in part to geographical distribution and degree of association with urban communities.

김흥철,Terry A. KLEIN,이원자,Brett W. COLLIER,정승태,William J. SAMES,이인용,이영재,이동규 한국곤충학회 2007 Entomological Research Vol.37 No.1

In 2005, adult and larval mosquito surveillance was conducted at selected sites in Korea to associate larval habitats with species distribution of mosquitoes of the Anopheles Hyrcanus Group (An. sinensis, An. lesteri, An. pullus, An. belenrae and An. kleini) and other mosquito species. Anopheles specimens belonging to the Anopheles Hyrcanus Group were identified to species level by molecular confirmation using the internal transcribed spacer (ITS)-2 within nuclear ribosomal (r)DNA. A total of 6644 mosquitoes from resting and light trap collections (4451; 67.0%) and larval collections (2193; 33.0%) comprising 32 species and nine genera (Culex [11], Anopheles [8], Ochlerotatus [5], Aedes [3], Armigeres [1], Coquillettidia [1], Mansonia [1], Tripteroides [1] and Lutzia [1]) were collected. Larval habitats were characterized into 14 categories. Of a total of 4534 Anopheles spp. collected (3766 resting and light trap collections and 768 larval collections), Anopheles sinensis (3194; 70.4%) was the most frequently captured, followed by An. kleini (813; 17.9%), An. pullus (299; 6.6%) and An. belenrae (129; 2.8%). Fourspecies of Anopheles (An. lesteri, An. sineroides, An. koreicus and An. lindesayi) were infrequently collected (<3.0%) at all sites surveyed by all methods of collection. Anopheles kleini, An. pullus and An. belenrae were collected in greater proportions in malaria high-risk areas north of Seoul, and were infrequently collected in other parts of Korea, where An. sinensis was the predominant Anopheles spp. captured. A total of 2110 culicine mosquitoes (685 adult collections and 1425 larval collections) comprising 24 species and eight genera were collected.

We report here on a case of diffuse sclerosing papillary carcinoma (DSPC), which is a subtype of papillary carcinoma of thyroid, in a 27-year-old female. The ultrasound images showed diffuse enlargement of the thyroid lobes and this was associated with underlying diffuse scattered microcalcifications and a heterogeneous hypoechoic background parenchyma that was without any masses. The CT image showeddiffuse scattered dot-like hyperdensities with bilateral multiple metastastic lymph nodes. Because making the cytological diagnosis of DSPC is still challenging, the radiological findings that show this disease's characteristic features may be important clues for making the correct diagnosis. <B>(Ko</B><B></B><B>rean J Endocrine Surg 2008;8:43-47)</B>

김흥철 대한교통학회 2016 대한교통학회지 Vol.34 No.1

The purpose of this study is to analyze the correlation and the causal relation between theservice quality, customer satisfaction and revisit intent of an urban railway. A structuralequation model(SEM) was developed and analyzed using SPSS 21.0 and AMOS 21.0. Theresults showed that it satisfies the fitness of the model mostly: the reliability, convenience,safety of the service quality have a significant positive impact on the customer satisfaction(p<.05) and the tangibles(-.187) and responsiveness(-.103) have no impact on the customersatisfaction (p>.05.). The customer satisfaction has a significant positive impact on revisitintention (p<.001). The factors affecting the service quality and customers’ satisfaction werefound to be ranked as the order of reliability, convenience, safety, responsiveness, tangibilitybased on the high priority. The findings of this study will contribute to provide a practicaltool to establish a mid-long term management plan and management strategies for boostingthe customer satisfaction and creating revenue through the customized service of urban railwayoperating industry suffering chronic deficit. 이 연구의 목적은 도시철도의 서비스품질과 고객만족도, 재이용의도 간 상관관계와 인과관계를 분석하는 것이다. 구조방정식모형(SEM)을 설정한 후 그것을 분석하기 위하여SPSS 21.0과 AMOS 21.0을 사용하였다. 분석의 결과 대부분 모형의 적합도를 만족시켰다: 서비스품질의 신뢰성과 편리성, 안전성은 고객만족도에 유의한 정(+)의 영향을 미쳤고(p<.05), 유형성(-.187)과 응대성(-.103)은 고객만족도에 영향력의 크기와는 관련이 없는 것으로 분석되었다(p>.05). 그리고 고객만족도는 재방문의도에 유의한 정(+)의 영향을미치는 것으로 분석되었다(p<.001). 고객만족도에 영향을 주는 중요도의 서비스품질의 우선순위는 신뢰성, 편리성, 안전성, 응대성, 유형성 순으로 나타났다. 이 연구의 결과는 향후 만성적인 적자로 허덕이고 있는 도시철도(경전철포함) 운영기관에게 고객맞춤형 서비스품질을 제공토록 하여 고객만족도 향상과 수익창출 위한 중장기 경영계획과 경영전략의 초석을 제공할 것이다.
