Objective To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi’s LM) and conventional 4-port LM. Methods A retrospective study of patients who underwent Choi’s LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with <3 symptomatic myomas sized <10 cm each and operated on by a single surgeon were included. Recurrence was confirmed when a myoma measuring ≥3 cm was detected. Results The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8±1.5 cm vs. 7.0±1.6 cm; P=0.40). In Choi’s LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi’s LM (3.4±0.7 cm vs. 5.7±2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. Conclusion Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi’s LM were acceptable. Considering its usability, Choi’s LM is feasible for the treatment of uterine leiomyoma.

2~4세기 고구려 지방통치의 발전과 대민지배의 강화

최희수(Choi, Hee-soo) 한국고대사탐구학회 2013 한국고대사탐구 Vol.13 No.-

이 연구의 목적은 2~4세기 고구려 지방통치가 어떻게 운영되었는가를 살피는 데 있다. 2세기 말부터 4세기 말에 이르는 시기는 지방통치체계가 발전하는 시기였다. 2세기 말부터 곡-촌 단위까지 파악이 되고 있다. 이 대민파악을 토대로 3세기 초에는 전기 의 1단계 통치체계에서 태수-재라는 2단계 통치체계를 구현했다. 때문에 민에 대한 파악과 관리가 훨씬 수월해지게 되었다. 그리고 광활한 영토가 확보되는 광개토왕대에는 필요한 지역에 수사직이라는 광역의 지방관이 설정되었다. 지방의 구조는 나부·성 - 성·곡 - 성·촌의 단위로 이루어졌다. 그러나 자연적인 지방단위보다는 인위적인 편제단위가 두드러지게 나타난 시기이기도 했다. 그럼으로써 개별적인 민에 대한 관리가 가능하게끔 편제를 하였던 것이다. 이 시기에는 가구 단위로 민을 파악하고 관리했지만 역역 동원시에는 해당역역의 특성에 따라 가 단위로 차출하거나 곡 또는 촌 단위로 차출을 했다 조세의 수취는 대체로 . 가구 단위의 빈부를 조사하여 차등적으로 징수했던 것으로 생각된다. The purpose of this study is how operated local ruling in 2-4 century period of Koguryo. From ending of 2nd century to ending of 4th century, the local ruling is developed more step. In the regional areas, Na-Bu and Seong-eup still existed. For each of these Seong-eup, Tae-soo(태수) and Jae(재) was dispatched, respectively to be responsilble for ruling. King Sansang(산상왕) carries out moves the capital to HwanDo-seong(환도성) in Kuknae area. From after that, local rulng system was upgraded. The local officer who called Soo-sa(수사) were dispatched in King Gwanggaeto period. They governed more wide area than Tae-soo or Jae. At this time, the local area was composed to Nabu Seong Chon. The operation of local rule the tax collection and manpower mobilization accomplished directly control.

KIM, Woon Soo* & CHOI, Yae Chin**(University of Ill., U.S.A.* & Chunchon Agricultural Coll.**) Studies on the viruses of radish mosaic. Kor. Jour. Bot. VI (2):9-21, 1963. A mosaic diseased radish collected from the suburb of Seoul, in November, 1961 was used for studing the host range, physical properties, purification, insect transmission, and electron microscopy. A Japanese strain of raddish mosraic (RPV) was also used with Korean strain of radish mosaic (KRMV) for a comparative study. The two viruses, KRMA and RPV, were identified by the difference in host range, insect transmission and electron microscopy. The KRMA was severely infective on tobacco and Nicotiana glutinosa, while on Gomphrena globosa was immune to the virus. RPV produces necrotic local lesions on Comphrena globosa but did not infect tobacco and N. glutinosa. Among varieties of radish, Seoul, Akamaroo, Akanagea, Koong-Joong showed more severe symptoms than Simoo, Minong, Paek-soo, which appeared to be fainly resistant. In a number of tests, it was found that the virus KRMA retained its infectivity until to a dilution of 1:2,000, heating at 58˚C for 10 minutes, and aging in vitro for 7 days at room temperature. The RPV was not inactivated until it was diluted to 1:2,000, heated to 56。C, and aged for 6days. The KRMV was readily transmitted by the aphid (Myzus persicae Sulz). The virus RPV was not transmitted by the aphid in a number of tests. Partialy purified viruses using ammonium acetate buffer, salting-out by ammonium sulfate and centrifugation of high and low speed were highly infective. Electron micrographs showed that the KRMV paticles are of spherical particles whereas the RPV particles are rod-shaped.

Human epithelial cell cultures were initiated from explants of normal human oral mucosa. Growth parameter and cell type were assessed by DNA concentration and morphology of the cell lines. Tissues were excised and epithelial cells isolated by collagenase digestion. Spermine was used in order to inhibit overgrowth of the epithelial cells by fibroblast. The effects of different medium formulations were compared. Cultures maintained on the same volume of RPMI 1640 and Dulbecco's modified minimum essential medium containing 10 % fetal bovine serum, 10 ?g/ml of insulin, lng/ml of somatomedin and 10 ng/ml of epidermal growth factor showed optimal and maximal growth. For each cultured human oral epithelial cell the DNA content was in the- range of 5.7 pg to 6.6 pg. This culture system provides epithelial cells that can be used for a variety of dental and biochemical studies.

최임수(Choi, Im-Soo) 한국국제회계학회 2020 국제회계연구 Vol.0 No.94

[연구목적] 본 연구의 목적은 신혼부부가 생애최초로 주택을 취득하는 경우 취득세를 감면해주는 제도의 실효성 확보방안을 제시하는 데 있다. [연구방법] 지방세특례제한법 제36조의2에 의한 2019년 취득세 감면현황, 2019년 전국 아파트 거래현황 및 각종 문헌을 검토하여 분석한다. [연구결과] 첫째, 기준 취득가액과 세액감면율의 상향조정이 필요하다. 2019년 이 제도를 처음 시행한 이후로 부동산 가격이 급등하였고, 지난 1년간 취득세 감면실적이 예상액보다 상대적으로 적어, 정책의 실효성을 담보할 수 있도록 시장여건 등을 반영할 것을 제안하였다. 둘째, 기준면적에 대한 정책대상자의 선호수준을 반영해야 한다. 신혼부부가 생애최초로 이용한 주택의 사용면적의 현황, 선호하는 면적 및 아파트 거래현황을 반영하여, 전용면적의 기준을 현행보다 상향할 것을 제시하였다. 셋째, 일몰연장을 지속적으로 하고, 일몰주기는 장기적인 관점에서 검토해야 한다. 신혼부부의 주거안정이라는 정책목표를 달성하기 위해서는 정책의 시차를 고려하여 이 제도를 계속 존치할 것과 감면주기를 최대한 장기로 정할 것을 제시하였다. [연구의 시사점] 본 연구는 신혼부부 생애최초 주택 취득세 감면제도의 실효성이 낮은 이유를 확인하였고, 정책입안자에게 그 개선을 위한 방안을 구체적으로 제시했다는 공헌점이 있다. [Purpose] The purpose of this study is on presenting effectiveness procurement plans of the system for reducing acquisition taxes when a newlywed couple purchases their first home. [Methodology] Acquisition tax reduction status in 2019 under Article 39-2 of Restriction of Special Local Taxation Act, apartment house transaction status in 2019 and various literatures are reviewed and analyzed. [Findings] First, it is necessary to upward adjust the base acquisition price and tax reduction rate. Since this system was first implemented in 2019, real estate prices increased significantly, and because the acquisition tax reduction was relatively lower than expected over the past year, it is proposed to reflect market conditions, etc. to guarantee the effectiveness of policies. Second, the preference levels of policy targets on the base area should be reflected. The current status of used area of homes that newlyweds use for the first time in their married lives, preferred area, and apartment transaction conditions were reflected to suggest that the standards for exclusive area should be upward adjusted. Third, sunset should be extended continuously and the sunset cycle should be reviewed from a long-term perspective. In order to achieve the policy goal of housing stability for newlyweds, policy lags should be considered and this should be kept in existence, while setting it in the longest term possible. [Implications] This study makes contributions in the respect that the reasons for low effect of acquisition tax reduction system for the first-time home of newlyweds are identified and that the methods for improvement are suggested in detail to the policy maker.

최민수 ( Choi Min-soo ),공양님 ( Kong Yang-nim ) 열린부모교육학회 2016 열린부모교육연구 Vol.8 No.3

본 연구는 유아 성폭력 예방교육활동을 통하여 만 5세 유아의 성지식 및 성태도에 미치는 효과를 검증하여 유아교육현장에 실효성 있는 유아 성폭력 예방교육활동의 적용 가능성을 모색하기 위한 목적으로 이루어졌다. 이러한 목적을 위하여 G광역시에 소재하는 K어린이집 유아 18명에게는 유아 성폭력 예방교육활동을 적용하였고, B어린이집 유아 19명에게는 일상적인 누리과정에 따른 교육활동이 적용되었다. 유아의 성지식과 성태도를 조사하기 위해 사용한 검사도구는 백라지(2004), 한선희(2005), 우민정(2010)이 사용한 도구를 김수미(2012)가 재구성하여 사용한 검사도구를 사용하였다. 자료분석은 독립표본 t검증으로 분석하였고, 통계적 유의도 수준은 .05 이상으로 하였다. 연구결과 유아 성폭력 예방교육활동의 적용효과는 유아의 성지식과 성태도에서 실험집단이 통제집단에 비해 통계적으로 유의미하게 높은 것으로 나타났다(p < .001). 본 연구결과를 통하여 유아 성폭력 예방교육활동 적용은 유아의 성지식 및 성태도를 증진하는데 효과적인 것으로 입증되었다. 즉, 유아 성폭력 예방교육활동을 체계적으로 경험한 유아들은 그렇지 않은 유아들에 비하여 성폭력 안전에 관련된 위협적인 상황이 발생했을 때 더 안전하게 위협에 대처할 수 있는 능력이 증진되었음을 나타내는 증거로 해석될 수 있다. 이러한 결과는 유아들에게 보다 적극적으로 성폭력 예방교육을 실시해야 할 시사점을 제공하고 있다. This study was carried out for the purpose of grouping the possibility of applying realistic, effective prevention education activities from infant sexual violences in infant education fields by verifying influencing effects on infants` sexual knowledge and sexual attitudes of 5-year in full through prevention education activities from infant sexual violences. For doing so, prevention education activities from infant sexual violences were applied to 18 infants in K Daycare Center located in G Metropolitan City, and educational activities according to daily Nuri process were applied to 19 infants of B Daycare Center. For the test tool having been used to investigate sexual knowledge and sexual attitudes, it was utilized after Kim Soo-mi (2012) recomposed the using tool by Back La-gi (2004), Han Seon-hee (2005), and Woo Ming-jeong (2010). Data analyse were done by independent sampling t-Test, and statistical significance level was made to over .05. Research results are same as follows. Prevention education activities from infant sexual violences appeared higher significantly at the experimental group than the control group in sexual knowledge and sexual attitudes.(p<.001). This finding indicates that prevention education activities from infant sexual violences was turned up as giving positive influences to whole sexual knowledge and sexual attitudes relatively rather than educational activities centering on life theme in Nuri process, and there were prominent differences from coping capabilities in the process of groping ways of doing practices when situations of doing threats on safety of sexual violences in infant education fields occur.
