국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.

波浪과 흐름이 共存하는 大河川 河口部인 洛東江 河口域에서 洛東江 河口둑을 基点으로 波浪, 흐름, 地形變動, 潮流, 洪水位等을 評價基準으로 하여 災害에 대한 基本的인 評價를 實施했다. 波浪, 潮流, 洪水位等이 水位上昇을 透發시켜 周邊地域을 浸水시킬 수 있는 危險性의 與否를 實測과 數値計算을 통하여 實施하였다. 地形變動은 實測만을 통하여 地形變動率을 調査하였다. 資料를 分析한 結果 洛東江 河口地域은 波浪, 흐름과 波浪이 共存하는 領域으로 區分된다. 數値計算結果에 의하면 河口部에서의 來襲波高가 直接 河口둑 水門과 주변構造物에 미치는 影響은 크지 않았다. 또한, 3次元 波高分布를 볼 때 河口 水路를 따라서 거슬러 올라오는 波浪의 影響은 거의 없었다. 洪水位와 流速은 災害를 透發시키는 主要因子로 評價되었다. 波浪에 의한 異常高潮와 漲潮流와 潮汐의 滿潮時間 및 最大洪水量이 時間적으로 一致되는 境遇, 河口둑 周邊地域의 水位 上昇과 流速의 停滯現狀으로 浸水狀態가 發生한다. For the investigation of inundation disasters by wave setup in the Nakdong Estuary of the Large River which waves and currents are coexist, the wave surveying data was analyzed and the numerical model was applied to the Estuary. In this study, the result of surveying data analysis shows that waves have little effect on the surroundings. As the result of numerical computation, waves have seldom direct influence upon the barrage and its gates. Also, according to three dimension distribution of waves, it is found that coming up waves along the Estuary channel and the setup of waves have seldom effect barrage structures.

Objective: To identify the impact of care given by gynecologic hospitalist on waiting time prior to final disposition in the emergency department. Methods: Since September 2016, the government adopted a pilot program to introduce hospitalist system in Korea. Gynecologic hospitalist system was implemented at a high-volume hospital since May 2018 for the first time in Korea. The hospitalist provided acute and/or palliative medical care in the emergency department (ED), intensive care unit (ICU), and at the general ward. Three-month data before and after the implementation of hospitalist system on the waiting time at the ED was analyzed. Waiting time was defined as the time of referral for gynecologic consultation by the ED staff to the time of final plan (disposition) given by the hospitalist formally through the consultation reply. Patients that were given care during the daytime (9AM - 6PM) were included for analysis. Results: The number of monthly gynecologic consultation during daytime at the ED were 11, 4, and 18 on February, March, and April (group 1), respectively. The number increased gradually after the implementation of the hospitalist system; 13, 21, and 22 patients in May, June, and July (group 2), respectively. The proportion of patients with conditions related to oncologic treatment (neutropenic fever, septic shock, bowel obstruction, etc.) was 60.7%. The number of patients with extended length of stay (> 12 hours) at the ED were 5 vs. 1 in group 1 and 2, respectively. The median waiting time prior to final deposition was 142 min (range 45 - 492 min) in group 1 (before hospitalist system) and 81 min (range 17 - 212 min) in group 2 (after hospitalist system). Conclusion: The waiting time of gynecologic patients upon ED admission was significantly decreased after the establishment of the hospitalist system. Further related to patient mortality and patient / staff satisfaction are needed.

Annular elastolytic giant cell granuloma initially misdiagnosed as granuloma annulare
( Ga Ram Ahn ),( Hyun Jung Kwon ),( Kui Young Park ),( Seong Jun Seo ),( Chang Kwun Hong ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Annular elastolytic giant cell granuloma (AEGCG) is a rare granulomatous dermatosis which is characterized by annular atrophic lesions which tend to occur in sun-exposed area. Due to its annular morphology and histopathologic feature which include a granulomatous infiltration with multinucleated giant cells, AEGCG is often difficult to be distinguished from granuloma annulare (GA). A 49-year-old woman was referred to our clinic presenting multiple annular lesions on her forehead, upper chest and both forearms and hand dorsa. With the initial impression of GA, she was treated with systemic steroid and UV-A therapy. Since the lesions progressed gradually in spite of the treatment, skin biopsy was performed. The biopsy specimen showed granulomatous hystiocytic infiltration with multinucleated giant cells engulfing fragmented elastin fibers. Herein, we report a case of AEGCG which was initially misdiagnosed as GA and discuss the clinical and histopathological differential diagnosis through review of literatures.

Surgical Outcomes of Sphenoid Wing Meningioma with Periorbital Invasion
Park, Ga-On,Park, Hyun Ho,Yoo, Jihwan,Hong, Chang-Ki,Oh, Jiwoong The Korean Neurosurgical Society 2022 Journal of Korean neurosurgical society Vol.65 No.3
Objective : The aim of this study was to evaluate the clinical outcome of sphenoid wing meningioma with periorbital invasion (PI) after operation. Methods : Sixty one patients with sphenoid wing meningioma were enrolled in this study. Their clinical conditions were monitored after the operation and followed up more than 5 years at the outpatient clinic of a single institution. Clinical and radiologic information of the patients were all recorded including the following parameters : presence of PI, presence of peri-tumor structure invasion, pathologic grade, extents of resection, presence of hyperostosis, exophthalmos index (EI), and surgical complications. We compared the above clinical parameters of the patients with sphenoid wing meningioma in the presence or absence of PI (non-PI), then linked the analyzed data with the clinical outcome of the patients. Results : Of 61 cases, there were 14 PI and 47 non-PI patients. PI group showed a significantly higher score of EI (1.37±0.24 vs. 1.00±0.01, p<0.001), more frequent presence of hyperostosis (85.7% vs. 14.3%, p<0.001), and lower rate of gross total resection (GTR) (35.7% vs. 68.1%, p=0.032). The lower score of pre-operative EI, the absence of both PI and hyperostosis, smaller tumor size, and the performance of GTR were associated with lower recurrence rates in the univariate analysis. However, in the multivariate analysis, the performance of GTR was the only significant factor to determine the recurrence rate (p=0.043). The incidences of surgical complications were not statistically different between the subtotal resection (STR) and GTR groups, but it was strongly associated tumor size (p=0.017). Conclusion : The GTR group showed lower recurrence rate than the STR group without differences in the surgical complications. Therefore, the GTR is strongly recommended to treat sphenoid wing meningioma with PI for the better clinical outcome.
