제주도 현무암에 포획된 페리도타이트에 산출되는 맨틀 기원의 CO₂-유체포유물
서민영(Minyoung Seo),우용훈(Yonghoon Woo),박근영(Geunyeong Park),김은주(Eunju Kim),임현수(Hyoun Soo Lim),양경희(Kyounghee Yang) 한국암석학회 2016 암석학회지 Vol.25 No.1
제주도 현무암에 산출되는 첨정석 페리도타이트 포획암에 CO₂-유체포유물이 포획되어 있다. 이 CO₂-유체포유물들은 규칙적인 결정면으로 둘러싸여 있으며 세립의 네오블라스트 결정에는 일차포유물로, 조립의 반상쇄성에는 이차포유물로 산출된다. 냉각/가열 실험에서 CO₂-유체포유물의 삼중점은 -57.1℃(±0.9℃)로서 대체로 균질하다. 이는 이 CO₂-유체포유물들이 거의 순수하게 CO₂로 이루어져 있음을 의미한다. 그러나 균질화 온도는 -39℃(ρ=1.12 g/㎤))에서 23oC(ρ=0.82 g/㎤))로 넓은 범위에 걸쳐 나타나며, 이는 많은 유체포유물이 포획된 이후 재평형 되어졌음을 반영한다. 일차/이차포유물과 균질화온도 사이에 체계적인 차이는 없다. 가장 낮은 균질화온도(즉, 가장 높은 밀도)를 보이는 유체포유물에서 계산된 포획 압력은 ≈0.9 ㎬이다. 제주 페리도타이트와 CO₂-유체포유물의 조직적 특성과 낮은 균질화 온도는 CO₂-유체가 맨틀기원의 유체로서 상부 맨틀암석권에서 페리도타이트의 재결정화 작용 동안 존재하던 유체로 해석된다. CO₂-유체의 포획은 제주 페리도타이트의 진화과정에서 후기의 사건이며, 상부맨틀 암석권의 상부(천부)에서 일어났음을 지시하고 있다. Negative crystal shaped CO₂-rich fluid inclusions, trapped as primary inclusions in neoblasts and as secondary inclusions in porphyroblasts, were studied in spinel peridotite xenoliths from Jeju Island. Based on microthermometric experiments, the solid phase melts at -57.1℃(±0.9℃) with no other observable melting events, indicating that the trapped fluid is mostly CO₂. The homogenization temperatures show a much wider range from -39℃(ρ=1.12 g/㎤)) to 23oC(ρ=0.82 g/㎤)), suggesting that most of the inclusions (originally trapped at mantle conditions) re-equilibrated to lower density values. Nevertheless, the highest density CO₂ in our fluid inclusions is consistent with entrapment of fluids at upper mantle pressures (and depths). The calculated trapping pressure from CO₂-rich fluid inclusions that appear to be free from re-equilibrium, e.g., showing the lowest homogenization temperatures, is ≈0.9 ㎬. Based on the petrographic evidences, the fluid entrapment can be regarded as a late stage event in the evolution of the shallow lithospheric mantle.

A base center for this study had established in Jeollabuk-do Province from Mar. to Nov. in 2020, and examined and monitored the pathogenic organs and the incidence frequency of infectious disease vectors, by collecting mosquitoes mediating such diseases, from cattle sheds (cowhouses) in Wanju County, Geumgang Estuary Bird Sanctuary as a migratory bird habitat in Gunsan City. There are total of seven urban areas in Jeonju City, with BG-sentinel traps and black light traps. The resulting number of the population collected was 14,195 (17 species, 7 genera). The highest number (9,006) of mosquitoes was found from cattle sheds in Wanju County, followed by the migratory bird habitat, and then, urban areas in Jeonju city . In all environments, Anopheles spp. (5,809, 40.9%) was most often collected, so it was thought to be dominant species. Each of dominant species by environments is as follows: Anopheles spp. in cattle sheds; Culex tritaeniorhynchus in Gunsan city and Culex pipiens pallens in urban areas. From Sep. to Oct., 23 individuals of Aedes linetopennis were collected from men’s rest rooms. The pathogenic organs were examined to show that the positive Japanese encephalitis viruses were found from one pool at cattle sheds in Wanju County. Quick and efficient measures may be developed, by verifying the incidence density of media, affected by the climate change in Jeollabuk-do Province and whether foreign media were introduced or not.

Introduction : One of the therapeutic goals for vestibular schwannoma (VS) is to preserve the function of cranial nerves, especially the facial nerve (FN). The purpose of this study was to determine the relationship between tumor origin, size and outcomes of FN function in VS surgery via translabyrinthine approach. Methods : To determine the characteristics of tumor and FN outcomes, medical records and MRI were reviewed retrospectively in a series of 39 patients who underwent gross total removal of VS via translabyrinthine approach. FN function was graded according to the House-Brackmann (H-B) grading immediately after surgery and at 1 year postoperatively. Results : The tumor originated from inferior vestibular nerve (IVN) was 38.5 % (n=15) and that of superior vestibular nerve (SVN) was 30.8% (n=12). Twelve out of 15 (80%) patients with IVN tumors and 10 (83.3%) out of 12 patients with SVN tumors achieved HB grade I-II facial nerve function at immediate and 1-year after the surgery. (p=0.825, p=0.396) In comparison between tumor size and FN function, immediate postoperative satisfactory FN outcome of HB I-III were achieved in 4 (80%), 8 (80%), 12 (70.6%) and 3 (42.9%) patients with intracanalicular tumor, tumor less than 1cm, 1.1-2.5cm and 2.6-4cm, respectively. One-year postoperatively, HB grade I-II could be observed in 4 (80%), 9 (90%), 13 (76.5%) and 4 (57.1%) patients. In overall, FN function of HB grade I-III was achieved in 71.8% immediately and 76.9% 1-year after surgery. Conclusions : The result of the facial nerve preservation did not differ significantly according to tumor location. The preservation of facial nerve function seems to be correlated with size of the tumor. More than 3/4 of VS patients could maintain their FN function of HB grade I-II after translabyrinthine approach at 1 year follow-up.

대구지역 어린이급식관리지원센터 지원 일부 어린이집 급식의 미생물적 품질 평가
서민영 ( Min-young Seo ),류경 ( Kyung Ryu ) 대한영양사협회 2019 대한영양사협회 학술지 Vol.25 No.1
This study examined the microbiological quality of daycare center meals. Six menu items from five daycare centers in Daegu included uncooked processed foods (seasoned cucumber and lettuce salad), post-preparation after cooking processed foods (rolled omelet and seasoned soybean sprout), and cooking processed foods (panbroiled beef with oyster sauce and seasoned pork roast). Microbiological analyses were performed for the aerobic plate counts (APC), coliforms, and Escherichia coli. The analyses were conducted in July and November 2017. The mean APC and coliform count of seasoned cucumber decreased significantly from 4.71 log colony forming units (CFU)/g and 2.50 log CFU/g in July to 4.07 log CFU/g and 1.78 log CFU/g in November, respectively (P<0.01 and P<0.001). The APC of panbroiled beef with oyster sauce and seasoned pork roast were significantly lower in July (1.84 and 1.79 log CFU/g) than in November (2.41 and 2.28 log CFU/g) (P<0.001). The coliform counts of panbroiled beef with oyster sauce and seasoned pork roast were significantly greater in November (2.11 and 1.62 log CFU/g) (P<0.001). E. coli was not detected. Among the foods prepared using the three preparation processes, the post-preparation after cooking processed foods had the lowest microbial quality. The APC and coliform counts of cooking processed foods were satisfactory in July, with an acceptable rating for pan-broiled beef with oyster sauce in November. Time-temperature control and the prevention of cross-contamination are essential during meal production for food safety, regardless of the season.

서민영 ( Min Young Seo ),임은미 ( Eun Mi Lim ) 한국아동교육학회 2010 아동교육 Vol.19 No.4
본 연구에서는 유·아동의 인터넷게임중독 경향을 분석하고 인터넷 게임중독경향과과 인성특성의 관계를 분석하였다. 또한 유·아동의 인터넷게임중독 경향과 인성특성은 어떤 관계가 있으며, 인터넷게임의 환경문제와 행동특성이 10가지 인성특성 중 어떤 특성과 관계가 있는지를 밝히고자 하였다. 연구대상은 전라북도 내 유치원과 초등학교 1, 2학년 남녀학생 317명이었고, 연구도구는 유아 및 초등학교 저학년 부모용 인터넷 게임중독 경향성 검사와 한국아동인성평정척도(KPRC)였다. 연구결과 유·아동의 인터넷 게임 중독 경향은 정상 사용자인 게임중독 경향 일반군이 대다수였으나 게임중독경향 위험군과 게임중독경향 잠재군도 11.6%나 있었다. 남자 유·아동의 인터넷게임 중독 경향이 여자 유·아동의 인터넷 게임중독 경향보다 강한 것으로 나타났으며, 유·아동의 인터넷게임 중독 경향은 학년이 올라감에 따라 강해졌다. 인터넷게임중독경향과 부정적 인성특성은 유의한 관계를 가지고 있었으며, 이러한 경향은 인터넷게임중독 경향의 하위요인인 게임환경문제와 게임행동특성 모두에게서 드러났다. 성별로 볼 때, 인터넷게임 중독 경향과 부정적 인성특성의 관련성은 여자 유·아동에게서 더욱 깊은 것으로 나타났고, 초등학교 1학년 아동보다 유아와 초등학교 2학년 아동에게서 더 깊은 것으로 나타났다. 인터넷 중독 경향이 유아기부터 발생하며 학년이 높아질수록 급속하게 강해진다는 점을 밝힌 본 연구의 결과는 정보문화에 대한 올바른 윤리교육과 인터넷중독 예방교육 및 상담이 인터넷을 처음 접하는 유·아동기에도 활발하게 이루어져야 함을 시사한다. This study is to understand infants` and low-grade elementary school studensts` internet-game addiction tendency and examine the relationship between internet game addiction tendency and personality characteristics of infants and low-grade elementary students. The subjects consisted of 317 children from a kinder-garden and an elementary school in J city. The survey tools were Korean Personality Rating Scale for Children(KPRC) and Internet Game Addiction Scale(IGAS). The respondents were the parents of the subjects. The results were as follows: About 11.6% of subjents were at the risky state of internet game addiction tendency. Male infants and children`s internet game addiction tendency was higher than females`. As age grew older, internet game addiction tendency became stronger. Internet game addiction tendencies were significantly related to personality characteristics. Among female infants and children, the relationship between internet game addiction tendency and personality characteristics was higher than among male infants and children. Also, among infants and 2nd grade children, the relationship between internet game addiction tendency and personality characteristics was higher than among 1st grade children. These results suggests that education and conseling programs protecting internet game addiction and computer misuse from infants and Children should be prepared.
