The patients with Eustachian tube disorder could complain of various symptoms, such as earfullness, tinnitus, hearing disturbance, otalgia, or autophony. It is important to accurately diagnose the disease and choose appropriate treatment method to prevent further complaints or complications from the disorder. For all types of Eustachian tube dysfunction, conservative therapy should be the first choice, especially when duration of the symptom is short or transient. Even if the symptoms do not improve and persist, surgical therapy could be considered. For the dilatory Eustachian tube dysfunction, surgical therapy includes ventilation tube insertion, adenoidectomy, and balloon Eustachian tuboplasty. For the patulous eustachian tube dysfunction, there are various surgical methods: ventilation tube insertion, mass loading on the tympanic membrane, invasive Eustachian tuboplasty, injection to nasopharyngeal Eustachian tube orifice, trans-tympanic or trans-nasal catheter insertion, and trans-tympanic silicone plug insertion. It is important to select the appropriate treatment methods according to the degree of improvement of symptoms.

두릅나무 '자오'의 체세포배 유도와 식물체 형성에 미치는 생장조절제 및 삼투압제 효과

김지아,문흥규,김용욱,Kim Ji-Ah,Moon Heung-Kyu,Kim Yong-Wook 한국식물생명공학회 2005 식물생명공학회지 Vol.32 No.2

체세포배 유도를 통해 두릅나무 역병 저항성 개체인 '자오'의 효율적인 재분화가 가능하였다. 절편에 따라 배발생 캘러스에 요구되는 생장조절제의 종류가 다르게 나타났다. 잎의 경우 MS 배지에 2,4-D와 TDZ, L-glutamine이 처리된 배지에서 캘러스와 체세포배의 유도가 양호하였으며, 엽병과 뿌리는 2,4-D 단독처리 시 가장 좋은 결과를 얻을 수 있었다. 적정 배양조건하에서 배발생캘러스 유도율은 잎, 엽병, 뿌리로부터 각각 75%, 67% 및 83%를 나타냈다. 삼투압제 처리에 따른 체세포배의 발아율은 sucrose, glucose, maltose모두 90% 이상의 발아율을 보였으나, 식물체 형성은 2% sucrose에서 72%로 가장 좋았다. 어린 식물체는 생장조절제를 첨가하지 않은 1/2MS 배지에서 정상 식물체로 생장하였고, 인공상토에 이식하여 95% 이상 순화하였다. 본 실험결과는 두릅나무 역병 저항성 개체 '자오'의 체세포 배발생을 통한 기내 대량증식이 가능함을 보여주었다. Effective micropropagation system via somatic embryognesis was established for a Phytophthora resistant Aralia elata cultivar. Different kinds of growth regulators were needed to induce embryogenic callus with different explant sources. When leaf explants were used, a combination of 2,4-D, TDZ and L-glutamine was needed, whereas when petiole and root explants needed only 1.0 mg/L 2,4-D. Embryogenic callus induction rate under the optimum culture condition was 75.0%, 67.0% and 83.0% from leaf, petiole and root segment, respectively. Somatic embryo germination and plantlet conversion rate appeared to be influenced greatly by various osmoticums. More than 90% of embryos germinated when treated with sucrose, glucose and maltose. However, the highest conversion rate (72%) was recorded on medium with 2% sucrose only. The converted plantlets grew normally on 1/2MS basal medium, were acclimatized on artificial soil mixture and survived more than 95% in the greenhouse condition. The results suggest that the species can be clonally propagated through in vitro culture system via somatic embryogenesis.

This study aimed to analyze the association between employment status change during Covid-19 pandemic andmental health in Koreans aged 19 years or older. The cross-sectional study of the Korea Community Health Survey (KCHS) was conducted on 172,747 individualsaged 19 years or older excluding missing value, Weighted chi-square, Weighed logistic regression were used to identify the association between employment status change and mental health. ‘Worse than before’ group had higher odds of Perceived Stress or Incidence of Depression than the ‘Better than before’ (AOR:1.159, 95 % CI: 1.06–1.27, AOR:1.433, 95 % CI: 1.13–1.81) respectively. after subgroup analysis by sex and age, Male and female group had a strong association between employment status change and pereived stress,but in terms of incidence of Depression, there were no association between employment status change and depression for female group. also, among under 64 years group, there were strong association between employment status change and mental health. but there were no association for over 65 years. The results of this study showed that the negative change of the status group had a higher rate of stress and depression than positive change of the status . Particularly, a strong association was observed in the male group and under 64 years group. Therefore, even if negative change of the stauts occurs, deterioration of mental health can be prevented by providing for mental health recovery policy.

아브젝시옹에 점령당한 주체 - 영화 <곡성>의 서사구조와 서사적 주체에 관하여 -

김지아 이화어문학회 2020 이화어문논집 Vol.51 No.-

본고의 연구 목적은 영화 <곡성>에서 제시된 모호성과 그러한 모호성 으로 인해 주체가 경험하는 혼란과 분열의 과정을 구체화하기 위함이다. 구체적으로 본고는 줄리아 크리스테바의 이론에서 주된 개념으로 제시되 는 아브젝시옹과 아브젝트를 중심으로 <곡성>에서 서사적 주체가 경험 하는 아브젝시옹과 이 아브젝시옹이 관객에게 미치는 신체적・심리적・상 징적 작용을 논증하고자 하는 것이다. 이에 본 연구는 크리스테바의 이론 에서 제시되는 주요 개념들을 설명하고 기존의 슬래셔 필름과 구별되는 <곡성>의 서사구조와 서사적 주체에 대해 탐구한다. 나아가 작품에서 기 존에 형성된 아브젝시옹의 해체와 재현, 그리고 아브젝트의 전치를 통해 <곡성>이 어떻게 아브젝시옹에 점령당한 주체를 구현하고 관객에게 아 브젝시옹을 체험하게 하는지를 살펴본다. The work to be analyzed in this study is the horror film “The Wailing”, which was made by Na Hong-Jin and premiered in 2016. The purpose of this research is to clarify the process of confusion and dissolution experienced by the subject (character) due to ambiguity and the ambiguity presented in the film. While existing research on The Wailing considered its ambiguity as a deceptive strategy, this paper aims to demonstrate not only the ambiguity experienced by the narrative subject in the movie but also, as a slasher film, how it incites the physical, psychological reaction of the audience, based on “abjection” and the “abject,” which are major concepts in Julia Kristeva philosophy. Therefore, the study explains these main concepts presented in Kristeva's theory and explores the process by which certain abjection is formed as the narrative of “The Wailing” develops. Furthermore, this paper looks at how “The Wailing” embodies the subject who is beset by abjection and allows the audience to experience such abjection.

원추각막 및 각막확장증에서 각막링 삽입술의 임상성적 비교분석

김지아,김동현,위원량,김미금 대한안과학회 2015 대한안과학회지 Vol.56 No.4

목적: 원추각막 및 각막확장증에서 인택스링을 이용한 각막링삽입술의 임상성적을 각막이식의 임상성적과 비교 분석하고자 하였다. 대상과 방법: 원추각막 및 각막확장증에서 2011년부터 2013년까지 인택스링을 삽입받고 3개월 이상 추적 관찰된 16명의 의무기록을 후향 분석하였다. 같은 질환으로 각막이식을 받고 1년 이상 추적 관찰된 30명과 비교하여 치료 후 시력(logMAR), 각막지형도의 변화,합병증을 비교 분석하였다. 링 삽입군에서 술 후 전안부 빛 간섭 단층촬영으로 측정한 삽입 깊이에 따른 교정 효과의 차이도 비교분석하였다. 결과: 수술 1년 뒤 링 군에서 logMAR 교정시력은 0.32로 0.20인 이식군에 비하여 낮게 나왔고, 시력 개선 정도 역시 링 군이 -0.23,이식군이 -1.51로 링 군이 교정효과가 작았다. 링 군의 술 후 각막곡률은 평균 45.20 ± 4.17D로 이식군에 비해 더 작은 곡률을 보였다. 3 mm 영역 부정난시는 6.93D로 이식군보다 컸다. 흔한 합병증은 링 주변 각막침착이 70%이었으나 시력에 영향은 없었다. 링삽입 깊이가 얕게 삽입된 군에서 각막곡률이 -8.49D 감소하여 깊게 삽입된 군보다 효과가 컸다. 결론: 원추각막 및 각막확장증에서 링 삽입술은 각막이식을 대치할 수는 없으나 교정효과가 있었다. Purpose: To report the clinical results after the implantation of intrastromal corneal ring segments (Intacs??) for the correction of keratoconus or keratectasia. Methods: This retrospective study was comprised of 16 eyes treated by insertion of intrastromal corneal ring and 30 eyes treated by penetrating keratoplasty (PKP) who were diagnosed with keratoconus or keratectasia. Visual acuity, refractive outcome, keratometric values were evaluated before and at 3 months, 6 months, and 12 months postoperatively. In addition, the implanted ring segment depth was measured by anterior segment optical coherence tomography and the results were compared based on the depth of the ring. Results: Twelve months after treatment, best corrected visual acuity (BCVA) was log MAR 0.32 at the ring group and log MAR 0.20 at the PKP group. BCVA change was larger at the PKP group than the ring group. Postoperative keratometric value was smaller at the ring group than at the PKP group. 3 mm irregular astigmatism was larger at the ring group than at the PKP group. The shallowly implanted ring group had a larger effect than the deeply implanted ring group. Conclusions: Intrastromal corneal ring segment implantation appears to be effective in improving the visual acuity and refractive outcome, although it cannot substitute for PKP.

셍온(Paraserianthes falcataria (L.) Nielsen)의 기내 부정줄기 유도 및식물체 재분화

Adventitious buds were obtained from isolated cotyledons cultured on MS medium with various concentrations of 6-benzylamino purine (BA) and thidiazuron (TDZ). The highest numbers of adventitious buds were obtained on MS medium supplemented with 0.2 mg/L BA. Experimental culturing with half the petiole portion and half with the terminal segments were grown on MS medium contained with 0.2 mg/L BA. Frequency of the adventitious bud induction was variable accordingly to the type of cultured explants. Explants with the half petiole showed the highest adventitious bud induction rate (80%) compared to explants of half with terminal segment (20%). An elongated shoot from the buds and growth of advent roots were both possible on the 1/2 MS medium without a plant growth regulator. These results offer an effective way in which clonal propagation can be accomplished.
