Seontae Kim,Longyu Jin,Jiyoung Suh,Heebae Ahn 대한미용의학회 2018 대한미용의학회지 Vol.2 No.1

Background: The success rates of conjunctiva-Müller muscle resection vary in reports of previous studies, with 81% to 88.6% success rates having been reported in other countries. Few studies have reported on the surgical success rates of conjunctiva-Müller muscle resection in Korea compared to the number of reports on other methods of blepharoptosis repair. We therefore sought to determine the clinical efficacy and success rate of conjunctiva-Müller muscle resection in patients with mild blepharoptosis and identify the factors that affect the surgical success rate. Objective: This study was performed to evaluate of the clinical efficacy and success rate of conjunctiva-Müller muscle resection (posterior approach technique) in patients with mild blepharoptosis and to identify the factors that affect its surgical success rate. Methods: Surgeries were performed by one surgeon in 30 patients (35 eyes) and only when the marginal reflex distance 1 (MRD1) increased over 1 mm at 5 minutes after the administration of 0.25% phenylephrine eye drops. The MRD1, MRD2, Brow-pupil distance (BPD), and interpalpebral fissure (IPF) were measured pre-operatively, 1 month post-operatively, and at the final follow-up visit. Results: The mean MRD1 increased significantly from 0.83±0.96 mm pre-operatively to 2.45±0.77 mm post-operatively (p=0.012). The mean IPF also increased significantly from 5.54±2.04 mm pre-operatively to 7.62±1.85 mm post-operatively (p=0.003). The mean BPD, however, did not change significantly (22.94±4.96 mm pre-operatively and 23.19±5.72 mm post-operatively, p=0.863). The post-operative MRD1 for the eye with blepharoptosis was less than 1 mm compared to that for the opposite eye. Conclusion: Conjunctiva-Müller muscle resection is a safe and effective surgical method in patients with mild or moderate blepharoptosis with good levator palpebrae muscle function in which the post-operative results can be predicted on the basis of the amount of muscle resection.

Objectives: This study aimed to identify potential safety signals and adverse events following the primary Pfizer-BioNTech coronavirus disease 2019 (COVID-19) vaccination series among children and adolescents aged 5 to 17 years in the Republic of Korea.Methods: Adverse events reported through the COVID-19 vaccination management system (CVMS, a web-based passive vaccine safety surveillance system) and adverse events and health conditions collected from a text message-based survey were analyzed.Results: A total of 14,786 adverse events among 5- to 17-year-old children and adolescents were reported in the CVMS; 14,334 (96.9%) were non-serious and 452 (3.1%) were serious, including 125 suspected cases of acute cardiovascular injury and 101 suspected cases of anaphylaxis. The overall reporting rate was lower in 5- to 11-year-old children (64.5 per 100,000 doses) than in 12- to 17-year-old adolescents (300.5 per 100,000 doses). The text message survey identified that local and systemic adverse events after either dose were reported less frequently in 5- to 11-year-old children than in 12- to 17-year-old adolescents (p<0.001). The most commonly reported adverse events were pain at the injection site, myalgia, headache, and fatigue/tiredness.Conclusion: The overall results are consistent with the results of controlled trials; serious adverse events were extremely rare among 5- to 17-year-old children and adolescents following Pfizer-BioNTech COVID-19 vaccination. Adverse events were less frequent in children aged 5 to 11 years than in adolescents aged 12 to 17 years.

It is well known that modifying the geometry or characteristics of heater surface is one of the effective ways in enhancing CHF. Also many researchers have been struggling to develop fine and fancy heater surface by various methods so far. Lately, there were lots of research about enormous CHF enhancement with nanofluids, which is well dispersed fluid with nano-sized particles, and it was proved that this phenomenon definitely depends on deposition of nanoparticle over heater surface. We have observed micro/nano multi-scale geometry and high wettability characteristic on naturally developed nanoparticle deposited heater surface from boiling experiment with nanofluid. On the base of this observation, we made micro/nano multi-scale surface with good wettability by MEMs technique, and conducted CHF experiments with them.

본 논문에서는, 자바 바이트 코드 검증을 위해 설계된 중간 표현 언어인 BIRS(Bytecode Intermediate Representation with Specification)생성기 JBVF(Java Bytecode Verification Framework)를 확장한다. JBVF를 통해 생성된 BIRS는 검증 조건 생성을 위해 자바 소스 코드(하이레벨)가 공개 되었을 경우에도 프로그래머가 BIRS(로우레벨)에 직접 명세 정보를 기술해 주어야 한다. 이를 해결하기 위해, 자바 소스 코드가 공개되었을 경우 자바 소스 코드에 입력된 명세 정보를 이용하여 BIRS 코드를 생성하는 방법을 소개한다. BIRS 코드는 JML2BML도구와 JML, BML을 이용하여 생성한다. BML을 입력으로 받아 생성된 BIRS에 명세 정보가 정확히 표현되었는지 확인한다. In this paper we extend JBVF(Java Bytecode Verification Framework). JBVF generates and verifies BIRS(Bytecode Intermediate Representation with Specification) which is an intermediate language for verifying bytecodes. When BIRS codes are genereted by JBVF, even though a programmer has java source codes(high level) annotated with specifications, he should describe specification information in BIRS codes(low level) for generation of verification conditions from BIRS codes. We present the way to generate BIRS codes from java codes annotated with specification information, when java source codes are available. We present how BIRS code is generated from BML. BML could be generated from JML by a tool JML2BML. We certify that specification information in BIRS from BML is correctly generated.

목포해양문학의 흐름과 과제

김선태(Kim, Seontae) 목포대학교 도서문화연구소 2012 島嶼文化 Vol.0 No.40

이 글은 목포 해양문학의 흐름과 앞으로의 과제를 살펴보는 데 목적이 있다. 목포 해양문학의 출발점을 1960년대에 맞추고, 2000년대까지 발표한 목포 출신 주요 작가들의 바다 관련 작품들을 선정한 다음, 그 흐름과 작품세계의 양상을 개략적으로 살펴보았다. 그 결과 목포의 해양문학은 뚜렷하지는 않지만 그 흐름이 지속되어 왔으며, 최근에 이르러 새로운 관심이 증폭되고 있음을 알 수 있었다. 그러나 작품세계를 살피는 과정에서 목포 출신 작가들의 해양에 대한 인식이 바다나 섬에 대한 막연한 동경이나 그리움, 어촌민들의 핍진한 삶의 반영, 설화나 전설의 차용, 바다에 대한 절망과 죽음에 대한 이미지 등에 머물고 있어 새로운 인식 전환의 필요성이 대두됐다. 즉 근래에 우리가 안고 있는 각종 해양문제를 문학적으로 반영할 필요가 있고, 그래야만 목포의 해양문학이 시대에 뒤떨어지지 않을 것임을 역설했다. 그리고 목포가 이러한 해양문학적 전통을 계승하여 앞으로 한국해양문학의 한 거점도시로 발전하기 위해 필요한 과제를 제시하였다. This study has its purpose to suggest the problems what Mokpo will solve in order to emerge as a hub city of Korean maritime literature by looking into the literary works, related with the sea, written by Mokpo birth and its current. To make this goal, the study, first of all, chooses 9 major writers from Mokpo with the history of Mokpo literature after modern times, and selects their literary works related with the sea; 1) Manseon(1964), a drama, and Nak-wol-do(1972), and Singoong(1977), novels written by Cheon, Seung-se, 2) Reminiscence about Poor This Year(1964) and Hwanghon(1976), poems, written by Choi, Harim, 3) At Yongdang-ri(1970) and The Sea, poems written by Kim, Ji-ha, 4) A Crane! It Could Be a Love(1975), a drama written by Cha, Beom-seok, 5) A Tale of Jangsan-do 1 and A Tale of Jangsan-do 2(1978), poems written by Kim, Chang-hwan, 6) A Woman in the Sea(1982) and Tango on the Sea(1991), poems written by Gwon, Il-song, 7) People without Longing Can’t See Aphae-do, a collection of poems written by Roh, Hyang-rim, 8) Goha-do : Ttangsi(1995) and In Front of Waves, poems written by Heo, Hyeong-man, and 9) At Samho Reclamation(1997) and Jogeum-saeggi(2009), poems written by Kim, Seon-tae. The study looks into the current and aspect of Mokpo maritime literature with the works. The results show that the maritime literature has kept up its unremarkable current at the cardinal point in 1960s, and recently new interests has been generated as well. In addition, the result shows that the writers’ recognitions about the sea stay in vague longing and missing about the sea or an island, reflection of fishermen’s poor lives, adoption from tales and legends, and negative images about the sea like despair and death. That is, new awareness conversion is needed. The study suggests some problems to be solved for Mokpo to develop to a future hub city of Korean maritime literature, succeeding to its unique tradition about maritime literature. They are as follows; First, Mokpo literature should be characterized as maritime literature to have uniqueness of local literature. Second, it is necessary to establish the first museum of maritime literature in Korea, which is a center to make a central role, located in Samhak-do of Mokpo or Aphae-do of Shinan. Finally, literary groups including the relative academic departments of local colleges and universities take the head to raise up young future generation who will lead the Mokpo maritime literature.

In this paper, we present a BIRS (ByteCode Intermediate Representation with Specification) and BIRS generator (JBVF, Java ByteCode Verification Framework) frameworks. We designed BIRS as an intermediate expression language which enables JAVA program verifications. BIRS generator parses JAVA bytecode and generates BIRS code which triggers stackless code transformations and program verifications. We implemented BIRS generator combining Sawja(Static Analysis Workshop for Java) library and OCAML module for transforming conveniences.
