A primary benign schwannoma of the liver is extremely rare. Only 30 cases have been reported in the medical literature worldwide, and only one case has been reported in Korea previously. A 56-year-old man was admitted to Gil Medical Center with incidental findings of a hepatic mass by abdominal computed tomography. The computed tomography and magnetic resonance image revealed a 3×2 cm-sized solid mass in the left lobe of the liver. Histological examination confirmed the diagnosis of a benign schwannoma, proven by positive immunoreaction with the neurogenic marker S-100 protein and a negative response to CD34, CD117, and smooth muscle actin. We report a primary benign schwannoma of the liver and review the literature. (Korean J Gastroenterol 2018;72:150-154)

New records of Sharks, Sphyran lewini and Alopias vulpinus (Pisces: Elasmobranchii) in Korea

최윤,김익수,나카야 카즈히로,Choi, Youn,Kim, Ik-Soo,Nakaya, Kazuhiro The Korean Society of Systematic Zoology 1997 Animal Systematics, Evolution and Diversity Vol.13 No.4

우리나라의 서해연안에서 채집된 상어류 2개체는 아직까지 국내에서는 보고된 바 없는 Sphyrna lewini(Griffith and Smith)와 Alopias vulpinus(Bonnaterre)로 동정되었다. S. lewini는 귀상어(S. zygaena)와 유사하지만 두부의 중앙부가 함입되엉 있고, 제2등지느러미 끝이 거의 꼬리지느러미에 달한다는 점에서 귀상어와 구분되었다. A. ulpinus는 환도상어(A. pelagicus)와 유사하지만 복부의 흰색이 가슴지느러미 기부 위까지 확장되고, 입의 양쪽 끝에 입술주름이 있어서 환도상어와 구분되었다. Two species of Sphyrna lewini (Griffith and Smith, 1834) and Alopias vulpinus (Bonnaterre, 1788) belonging to the Elasmobranchii were collected form the first time from the western coast of Korea. S. lewini is similar to S. zygaena, but differs in some morphological characters: a prominent median indentation on anterior margin of head and free rear tip of second dorsal nearly reaching upper caudal origin. a. vulpinus differs from A. pelagicus in having labial furrows, long terminal lobe and white ventral coloration extending above the pectoral fin bases.

외국산 참서대과(Cynoglossidae) 어류 2종

최윤,CHOI Youn 한국수산과학회 1996 한국수산과학회지 Vol.29 No.2

Morphology of two foreign species of tongue soles (Cynoglossidae), Cynogiossus browni and C. senekalensis, was observed based on specimens collected from Kunsan fish market from 1992 to 1994. These species are externally similar to Cynoglossus robustus from Korean coast. But these are quite distincitive from Cynogiossus robustus by interlinear scale rows, body size, other counts and proportional measurements of body. The Cynogfossus browni and C. senegalensis are only distributed in western coast of Africa and commercially imported to Korea through Pusan fish market.

최윤,Choi, Youn 한국어류학회 2009 韓國魚類學會誌 Vol.21 No.1

Greate white sharks, Carcharodon carcharias, are found in almost all the temperate and tropical coastal waters around the world. There have been 19 appearances reported in Korean coastal waters since June 1996 and seven shark attacks have been reported. There are about 400 species of sharks in the world, and 41 species of them have been found in Korean coastal waters. Thirteen of them belong to the Carcharhinidae family, and five of them belong to the Squalidae family. Of these sharks, 15 species of them live off of the East coast, 18 species live off of the West coast, and the other 40 species are distributed around Jeju Island and the South coast. Eleven species of them, including the great white shark, live off of all the coastal waters of Korea.

한국 서해연안 참서대 Cynoglossus joyneri G$\ddot{u}$nther의 생태

최윤,김익수,유봉석,정의영,박종영,Choi, Youn,Kim, Ik-Soo,Ryu, Bong-Suk,Chung, Ee-Yung,Park, Jong-Young 한국어류학회 1995 韓國魚類學會誌 Vol.7 No.1

한국 서해 연안 저서어류의 우점종인 참서대 Cynoglossus joyneri의 생태를 조사하기 위해서 서해연안 7해역에서 1992년부터 1994년까지 표본을 채집하였고, 채집된 표본들에 대해 성성숙, 난 자치어의 분포, 소화관 내용물을 분석하였으며, 서식해역의 저질(低質), 수온과 염분농도 등 서식환경을 조사하였다. 군산 연안에서 금강, 만경강의 담수 영향으로 염분농도가 크게 낮아지는 하계에 본 종의 출현량이 격감하였는데, 이 시기에 담수 영향권에서 벗어난 외해쪽에서 산란과 초기성장이 이루어지는 것으로 여겨진다. 생식소 분석 결과 이들의 산란기는 6~10월이었으며 산란성기는 7~8월이었다. 성숙란을 가지 는 최소성체는 143.5 mm로 부화 후 약 20개월 후에 성체로 되는 것으로 나타났다. 연령별 체장조성은 당년 부화한 부유기 단계의 개체들이 전장 30.0~70.0 mm, 1년생이 49.0~133.0 mm, 2년생이 128.0~ 167.0 mm, 3년생이 169.0~202.0 mm, 4년생이 200.0~240.0 mm였다. 소화관 내용물은 전장8cm 미만의 개체들의 경우 요각류와 갑각류 유생 등, 무척추동물의 유생이 대부분이었고 성체의 경우는 겨울철에 갯지렁이류, 여름과 가을철에 이매패와 새우류를 많이 섭식하고 있었다. 현재 참서대의 주요 먹이인 무척추동물이 서식하고 있는 서해 내만역은 개발에 따라 매립이 진행되고 있어서 앞으로 본 종의 출현량이 크게 감소할 것으로 예상된다. Ecological study of the Cynoglossus joyneri was conducted based on the specimens from the western coast of Korea from 1992 to 1994. Ecological characteristics of this species such as gonadal development, occurrence of larvae, stomach contents, and environmental conditions were investigated. Few larvae of Cynoglossus joyneri occurred in Kunsan coast. This coast is influenced by the freshwater input of the Mangyong and Kum River, especially during the summer. Therefore, the larvae of C. joyneri were considered to be spawned and grown during their early life stage in the high saline water in outer bay. Spawning occur from June to September, having the peak spawning period from July to August. Biological minimum size of matured fishes containing mature oocytes is about 143.5mm in total length, which requires about 20 months after hatching. The ranges of total length by age are as follows : 0-ring group(floating stage), 30~70mm ; 1-ring group, 49.0~133.0mm 2-ring group, 128.6~167.0mm ; 3-ring group, 169.0~202.0mm ; 4-ring group, 200.7~240.0mm. The major food items of young fish under 8cm were copepods and invertebrate larvae, and those of adult fishes were annelids(polychaets) in winter, and bivalves and shrimps in summer and autumn. Therefore, it can be assumed that the population of C. joyneri could be reduced due to the decrease of food organisms caused by the continuous reclamation activities in the inner bays of the west coast of Korea.

영유아 항공 여행 안전성에 관한 고찰

김선아,최윤서,김선이,Kim, Sun Ah,Choi, Youn Seo,Kim, Sun Ihee 한국항공운항학회 2018 한국항공운항학회지 Vol.26 No.3

It is mandatory to use car seats for infants and children in the private vehicles in accordance with the traffic law of Korea. Recently, legislation has also been proposed to expand the use car seats to express and intercity buses. This reflects a growing consensus that mandatory infant and child car seats, both for private and commercial vehicles, are essential. However, Korean laws concerning infants and children on board aircraft allow parents or guardians to hold children under two years of age on their laps without any restraint devices. It is not possible for a parent to physically restrain an infant or child, especially during a sudden acceleration or deceleration, unanticipated or severe turbulence, or impact. The use of CRS provides an equivalent level of safety to infants and children as that afforded to adult passengers wearing seat belts. But there is no regulation even about Child Restraint Systems on board aircraft in Korea. To enhance their safety, infants and children should be restrained in an approved child restraint system that is appropriate to their weight and height. It is necessary to examine whether infants and children in flight can achieve the same level of safety as an adult.

우리나라 수사절차 구조 개편에 관한 연구

정웅석(Jeong Oung Seok),최윤이(Choi Youn Yi) 한국형사소송법학회 2018 형사소송 이론과 실무 Vol.10 No.1

대륙법계 체계와 영미법계 체계 중 어느 제도가 더 훌륭한 것인지에 대해서는 각국의 사법체계는 저마다의 역사적 배경과 경험, 문화에 기인하여 각각 형성된 것이니만큼 그 우열을 가리기 어려울 뿐만 아니라 무엇이 더 나은 제도인지를 판단하는 것도 의미가 없다. 따라서 어떤 법체계를 받아들일 것인지 여부는 국민의 몫이라고 본다. 그러나 적어도 영미법계의 입법례로 수사구조를 개편하건 대륙법계 입법례를 그대로 유지하건 삼권분립의 원리를 수사・소추・재판으로 이어지는 국가형벌권을 실현하기 위한 연속적 절차에까지 유추적용하여 경찰・검찰・법원에 분배해야 한다는 논리는 검찰개혁과 아무런 관련이 없다는 점을 유념해야 할 것이다. 다만, 사견으로는 어떤 수사구조를 취하더라도 범죄인에게 유죄를 받도록 하는 것이 수사기관의 역할이라면 검사가 수사내용을 모른 채 재판에 임하는 경우 어떻게 중요한 사안에서 피고인 측 변호사와 법리적 다툼을 할 수 있는지 궁금하다. 즉, 단순히 수사/기소만을 분리하는 경우 피고인 측 변호사 등은 수사자료를 전부 분석하고 공판에 임하는데, 검사는 경찰이 보내준 자료만을 중심으로 재판을 준비하는 경우 지금보다 실체적 진실을 명확하게 밝힘으로써 유죄를 더 잘 이끌어낼 수 있을지 의문이다. 이 점에서 2018년 6월 21일 발표한 검/경 수사권조정 개편안(정부합의문)은 영미법계 수사구조도 대륙법계 수사구조도 아닌 경찰과 검찰의 문제있는 부분만을 억지로 짜깁기한 잘못된 개혁안이다. 결국 우리나라의 경우 검찰개혁이라는 시대적 요청에 부응하기 위해서는 수사절차의 구조개편보다는 검찰의 정치적 중립성을 어떻게 확보할 것인가 하는데서 그 해답을 찾아야 할 것인바, 정치권력으로부터의 인사권의 자유, 즉 청와대 등 권력집권층과 검찰 상층부의 연결고리를 끊는 것만이 검찰의 정치적 중립성을 확보하는 최상의 방안일 것이다. 그리고 이러한 정치적 중립성 및 공정성을 확보한 검찰이 해야 할 본래적 기능은 권력층이나 대기업・언론 등 소위‘힘 센’ 자의 부정부패의 척결과 경찰에 대한 법치국가적 통제를 통하여 국민의 자유와 인권을 보장하는 것이라는 점을 강조하고 싶다. As to which system of law is better, it is hard to answer because the legal system of each country is more difficult to distinguish from its historical background, experience and culture. Therefore, it is the people s responsibility to decide which legal system to adopt. However, the government should implement the principle of separation of powers to the investigation, prosecution, and trial, regardless of whether to change the structure of the investigation or maintain the law enforcement system, in order to realize the right of punishment. However, if it is the role of an prosecutor to make a criminal be convicted of any investigation structure, it is questionable how the prosecution could discuss the legal issues with the defense counsel in the case of a trial without knowing the investigation. In other words, if the prosecution merely separates the investigation and indictment, the defense counsel will analyze all the investigation data and attend the trial, whereas the public prosecutor will prepare for trial with data sent from the police only. In this case, is it possible that the public prosecutor could seek justice and obtain conviction decisions from the court appropriately and effectively? In criticism of the system of Adversary, “Should legal decisions and ultimate justice, whether American or Korean, accept a system that relies on the powers of the litigants and the skills of the lawyers?” This is why we ask the fundamental question. In the end, in order to meet the demands of the prosecution reform, the government should seek answers from the prosecution s political neutrality rather than the restructuring of the investigation procedures. And the original function of the prosecution, which has secured such political neutrality and fairness, is to ensure the liberty and the civil rights of the people by eradicating corruption in the so-called “powerful” and controling the law enforcement of the police.

Simple hepatic cysts are common benign liver lesions that usually have no malignant capability. They are generally asymptomatic and are often found incidentally by abdominal imaging procedures. Treatment becomes necessary, however, when huge hepatic cysts cause symptoms and develop complications, such as hemorrhage, adjacent organ damage, and infection. Several therapeutic options have been performed for symptomatic and huge cysts, including the aspiration of cystic fluid, infusion of various sclerosing agents, and surgical intervention. The optimal management of huge hepatic cysts is controversial and each option has its complications and limitations. This paper reports a case of a 66-year-old woman diagnosed with a simple hepatic cyst 2 years earlier, who was referred to hospital due to abdominal pain. The diagnosis was a huge hepatic cyst with symptoms by abdominal imaging studies. During the follow-up period, the huge cysts resolved spontaneously without treatment.

효과적인 공문서 바로쓰기 교육을 위한 교재 구성 방안

최홍열(Choi, Hong-Yeol),최윤(Choi, Youn) 강원대학교 인문과학연구소 2014 인문과학연구 Vol.0 No.42

공문서 작성법 교육은 교육 여건상 제약으로 인해 학습에 효과적인 교재 마련이 시급하다. 지금까지 다양한 종류의 교재가 발간되었으나 학습 효과의 측면에서 평가해 보았을 때 교재 구성에 아쉬움이 많았다. 본 논문에서는 최홍열 외(2013)와 최홍열?최윤(2014)에서 얻은 자료를 토대로 학습과 강의에 좀 더 효과적으로 활용할 수 있는 공문서 작성법 교재의 구성 방안을 알아보았다. 본 논문에서 논의한 것과 같이 오류 빈도와 중요도를 바탕으로 교재를 구성하고 기존에 발간된 교재를 참고하고 개선한다면 더욱 효과적인 교재를 개발할 수 있을 것이다. 또한, 이후 연구 사업을 통해 마련될 자료를 바탕으로 소통성 평가에 따른 세부 항목을 추가하여 교재를 구성한다면 더욱 효과적인 교재 구성 방안을 마련할 수 있을 것으로 보인다. Due to a range of constraints, there is an acute shortage of effective teaching materials associated with a method of writing official documents. In fact, a variety of teaching materials have been published for many years. However, none of them has led to noticeable education effect because of their structures. Based on data collected from prior research (Choi et al., 2013; Choi, H.Y. & Choi, Y., 2014), the current study discusses a way to create a teaching material that can be utilized effectively for lectures and other learning environments. As discussed in this study, it is important to take into consideration the frequency and significance of errors and improve previously published textbooks in order to develop a more effective teaching material. Moreover, if the communicative competence of official documents is assessed in further research projects and resulting details are included appropriately, it will be possible to design an influential teaching material.
