Myanmar is located in the south-east Asia peninsular and it is flanked by five neighboring states: Bangladesh, India, China, Laos and Thailand. It is located 10~22 degree north latitude, to 92~101 degrees east longitude. Myanmar has a tropical climate with three seasons in Myanmar. Hot season (March through April), rainy season (May through October) and the cool season (November through February). The coastal regions can get very hot and humid, especially before the rainy season. Myanmar has a monsoon season from May to October when there are heavy rains and often flooding. The investigation was carried out during the dry season(2013) in Nat Ma Taung National Park and Popa Mountain Park. Popa Mountain Park is located in Kyawpadaung Township, Myinchan district, Mandaly Division. The area is 49.63 square miles. Its coordinates are 29°31'60" N and 27°43'60" E. Nat Ma Taung National Park, Myanmar treasure is in Mindut District of Chin State and its area of 279 square miles. It is the third highest mountain in Myanmar with the height of 10,500 feet. Its coordinates are 21°14'00" N and 93°54'00" E. As the result, butterflies(Lepidoptera) collected in the two regions were about 60 species of 7 familys. Collecting dates, expedition activities, photo of main specimen and information of Myanmar were provided.

This study carried out for establishing the synthetic restoration plan to improve ecological quality of Mt. Mudeung National Park based on the results of conservation value assessment for yellow-throated marten habitats. Yellow-throated marten has significant implications as umbrella species for the wildlife habitats conservation, therefore, this species could be used to ecological restoration plan of the damaged forest ecosystem in Mt. Mudeung National Park. In this study, we diagnosed the quality of yellow-throated marten habitats in Mt. Mudeung National Park based on five natural and two artificial factors. In addition, we evaluated the integrity of each zone divided by trails quantitatively based on land use intensity. As a result, forest landscape quality in Mt. Mudeung National Park was influenced greatly by human activity and the degree was depended on the intensity of trails. Therefore, in this study, we suggested the closing of trails composed of the illegal and 36 legal trails. And then, we modeled the changes of habitats quality of Yellow-throated marten for each closing step. As a result the area of core habitats increased by two times and wildlife habitats quality improved in the whole area of the Mt. Mudeung National Park. As a result, the results of this study indicate that man-made linear landscape elements play a key role in the quality of habitats for predators, which require large habitats area like the Yellow-throated marten. Therefore, in order to establish an ecological restoration plan in the mountainous area, we recommend the concept of the linear landscape should be applied with the concept of area landscape.

공매도의 수익률예측성과 미래이익반응계수에 관한 연구

이용석(Lee, Yong-Seok),박희진(Park, Hee-Jin),김범준(Kim, Bum-Joon) 한국국제회계학회 2018 국제회계연구 Vol.0 No.78

본 연구의 목적은 기업별 공매도 체결내역을 기초로 공매도 거래와 회계정보의 유용성 간의 관련성을 분석하는 것이다. 일반적인 주식투자에 비해 공매도는 상대적으로 위험이 큰 투자안이므로 공매도 투자자는 위험을 회피하기 위하여 보다 적극적으로 회계정보를 활용할 가능성이 높다. 이에 본 연구에서는 공매도 투자자가 공매도 거래시 기업의 영업성과와 관련된 회계정보를 어떻게 활용하는지를 살펴보았으며, 추가적으로 FERC 모형을 이용하여 거래비중이 높은 기업에서 당기 주식수익률이 미래이익을 보다 정확하게 반영하고 있는지를 분석하였다. 분석결과, 투자자가 공매도 거래시 기업의 영업성과와 관련된 회계정보를 이용하여 추가적인 양(+)의 초과수익을 달성할 수 있음을 확인하였으며, 이를 통해 공매도 투자시 회계정보를 활용할 충분한 유인이 존재함을 보였다. 아울러 공매도 거래비중이 높은 기업에서 당기주식수익율과 미래이익간의 양(+)의 관련성이 더 높은 것으로 나타나, 공매도 거래비중이 높은 기업일수록 당기수익율이 보다 정확하게 미래이익을 반영하고 있다는 점을 실증적으로 제시하였다. 공매도는 전문적 투자자가 투자대상기업의 내재가치 변경을 예상할 때 발생한다는 선행연구의 결과와 유사하게 본 연구는 공매도 투자시 투자기업의 회계정보가 투자의사 결정의 유용한 정보가 될 수 있음을 보였으며, 공매도 투자자가 기업의 미래수익률을 보다 정확하게 예측한다는 Drake et al.(2011)의 연구결과가 국내 주식시장에서도 일관되게 나타난다는 점을 확인하였다. 공매도 거래비중이 높은 기업일수록 기업의 미래이익반응계수가 상대적으로 높은 것으로 나타났는데 이는 공매도 투자자들이 자본시장에서 회계정보를 잘 이용하게 할 수 있는 정보 촉매제 역할을 하고 있음을 시사하는 것으로 Pownall and Simko(2005)의 주장과도 일치되며, 직접적인 공매도거래가 아닌 대차잔고를 이용하여 연구를 실시한 Drake et. al.(2015)의 연구결과와도 유사한 결과이다. 본 연구는 자본시장에서 공매도 투자자가 정보중개인의 역할을 수행하고 있다는 점을 밝혔으며, 아직까지 공매도에 대한 인식에 차이가 존재하는 금융당국 · 투자자 및 기업들에게 공매도에 대한 유용한 새로운 시각을 제공한다. The purpose of our study is to analyze the relationship between the short sale transaction and the usefulness of accounting information based on the short sales transaction data. Since short selling is relatively high risk compared to stock trading, short selling investors are more likely to actively use accounting information to avoid risk. In this study, we investigate whether short selling investors use accounting information related to the company"s performance when doing short selling. In addition, we use the FERC model to analyze whether the current profitability is more accurately reflect future profit. According to the result of our analysis, investors can obtain additional positive earnings by using the accounting information related to the performance of the company during the short sale. Therefore, we find that there is sufficient incentive to utilize the accounting information in the short sale investment. In addition, the relationship between the future profit and the stock return is higher in companies with a high volume of short selling, suggesting that firms with higher volume of short selling would likely to reflect future earnings more accurately in the current stock return. Based on the prior research that short selling can be occurred when a professional investor expects to change the intrinsic value of firm, this study shows that the accounting information can be useful for investment decision. In addition, we also find that short-selling investors, who can be regarded as professional investors, predict the firm’s future returns more accurately, confirming that the empirical results of Drake et al. (2011) consistently apply in Korea stock market. Our results are consistent with the finding of Pownall and Simko (2005), which shows that firms with high short-sale volume have relatively high future earning-response coefficients, suggesting that short-selling investors have a role as information catalysts. We find that short selling investors play the role of information intermediaries in the capital market and provide a new insight on short selling to financial authorities and investors who still have differences perspectives in short selling transaction.

항정신병약물 사용 중인 정신분열병 환자에서 올란자판으로의 교체 방법에 관한 연구(II) : Comparison of Safety 안전성 비교

안용민,권용실,권준수,민성호,박두병,양문정,소형석,송종호,신윤식,우행원,유범희,이홍석,정한용,한창환,김용식 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.5

연구목적: 이 다기관 공동임상연구는 사용 중인 항정신병약물을 ’직접 교체 방법’또는 ’시작-감량 교체 방법’중 한 가지 방법으로 올란자핀으로 교체한 후, 안정성 측면에서 두 교체 방법 간의 비교와 교체후의 변화를 관찰하기 위한 것이다. 방법: 국내 13개 병원의 입원 및 외래에 내원한 환자들 중 ICD-10 지단기준으로 정신분열병에 해당되며, 임상적으로 항정신병약물 교체가 필요한 환자를 대상으로 하였다. 두 가지 교체 방법 중 한 가지를 무작위로 피험자에 적용하였으며, ’직접 교체 방법’에 배정된 경우에는 사용중인 항정신병약물을 일시에 중단하고 10㎎의 올란자핀을 바로 투여하였고, ’시작-감량 교체 방법’에 배정된 경우는 10㎎의 올란자핀 투여하고 2주에 걸쳐서 기존 약물을 감량하여 중단하였다. 올란자핀 사용기간은 총 6주이며, 용량은 5∼20㎎ 범위로 제한하였다. 한정성 평가를 위해서 체중, 생명징후, 자발적인 이상반응 복, 실험실 검사 그리고 Simpson-Angus Scale(SAS), Barnes akathisia rating scale(BARS), Abnormal involuntary movement scale(AIMS). Liverpool University neuroleptic side effect rating scale(LUNSERS)등을 이용하였다. 결과: 총 103명의 정신분열병 환자를 대상으로 하였다. 사용한 올란자핀의 용량, 벤조디아제핀의 병용률, 탈락률과 탈락 사유, 자발적인 이상반응 보고, 생명징후, 실험실 검사 그리고 대부분의 부작용 척도 상에서 임상적으로 의미 있는 차이를 두 교체 방법간에 발견하지 못하였다. 다만 AIMS의 감소는 ’직접 교체 방법’군에서 보다 적었고, 항콜린제의 병용률은 ’시작-감량 교체 방법’군에서 보다 많았다. 기저 상태에서 전체 피험자의 SAS와 BARS 점수는 각각 3.5점과 1.8점이었으며 70% 이상의 피험자가 고프로락틴 혈증을 보였다. 올란자핀으로 교체한 후, SAS, BARS, AIMS 점수의 유의한 감소가 있었으며 고프로락틴 혈증을 보인 피험자 분율도 약 30%이하로 감소하였다. 그러나 교체 방법과 상관없이 올란자핀 교체 후 유의한 체중 증가가 있었다. 결론: 이 연구를 통해 교체 방법에 관계없이 비교적 안전하고 용이하게 올란자핀으로 교체 할 수 있음을 알 수 있었다. 그리고 기존 항정신병약물을 올란자핀으로 교체함으로써 일부 부작용들을 줄일 수 있음을 간접적으로 관찰할 수 있었다. 하지만 이 연구는 여러 제한점과 문제점을 지니고 있기 때문에 보다 체계적인 연구를 통해 검정이 필요하리라 생각된다. Objectives: This multicenter clinical trial involving 13 hospital sites compared the safely of switching to olanzapine between ’direct switching method’ and ’start-tapering switching method’. Method: This study included both inpatients and outpatients who fulfilled the criteria for schizophrenia as defined in the ICD-10, and were in need to be appropriate for switching antipsychotics. Subjects were randomly assigned to one of the two switching methods. For ’direct switching method’group, previous antipsychotics were abruptly discontinued and 10㎎ of olanzapine was administered, and previous antipsychotics was gradually tapered for 2 weeks. Olanzapine was used for 6 weeks and the dose was adjusted within the range of 5-20㎎. The safety of switching to olanzapine was measured with vital sings including body weight, adverse events reported spontaneously, laboratory tests, and various scales such as Simpson-Angus Scale(SAS), Barnes Akathisia Rating Scale(BARS). Abnormal Involuntary Movement Scale(AIMS), and Liverpool University Neuroleptic Side Effect Rating Scale(LUNSERS). Results: 103 patients were switched to olanzapine in this study. The comparison between two switching methods did not show any significant difference in the dosage of olanzapine used, the concomitant use of benzodiazepine, the rate and reasons of drop-out, the adverse events, vital signs, laboratory tests, and most scales for measuring side-effects. However, the decrease in AIMS scores was significantly lower in ’direct switching method’ group, and the concomitant use of anticholinergics was comparatively greater in ’start-tapering switching method’ group. At baseline, SAS and BARS scores were 3.5 and 1.8 points respectively, and more than 70% of the subjects showed hyperprolactinemia. After switching to olanzapine, SAS, BARS, and AIMS scores were significantly decreased and the proportion of the patients with hyperprolactinemia was also decreased to less than 30%. However significant weight gain after the treatment of olanzapine was observed regardless of switching method. Conclusion: This study may suggest that switching to olanzapine can be done with relatively high safety regardless of switching methods and olanzapine can significantly decrease some side-effects induced by other antipsychotics.

구개부 소타액선에 발생한 호산성 과립세포종

박현진,김경원,조용석,이경호,강지연,최희원 충북대학교 의학연구소 2002 忠北醫大學術誌 Vol.12 No.2

호산성 과립세포는 타액선을 포함하여 갑상선, 부갑상선 등 주로 선조직에서 발견되는 커다란 과립상의 호산성 상피세포를 말한다. 호산성 과립세포종은 모든 타액선 종양중 약 1.5%의 비율로 발생하는 비교적 드문 양성 종양이며, 주로 노년의 이하선에서 발생하고 악하선과 소타액선에서는 드물게 발생한다. 임상적으로 크기는 약 3-4 ㎝이며 잘 분화된 낭으로 싸여있다. 조직학적 검사에서 광학현미경상 호산성 과립세포로 채워진 세포질이 관찰되며 전자현미경상 과립을 함유한 다량의 비대된 미토콘드리아가 관찰된다. 호산성 과립세포종은 본질적으로는 양성 종양이며 치료를 위하여 완전한 절제가 추천된다. 국소적인 재발은 드물며 다발성인 경우에는 재발하기도 한다. 증례는 38세의 남자 환자로서 구개부의 소타액선에 발생한 약 2.0×2.5 ㎝ 크기의 무통성의 종괴로 절제술을 시행하였으며, 광학현미경과 전자현미경을 이용한 조직병리 검사상 호산성 과립세포종으로 진단되었으며, 수술 후 특별한 합병증 없이 치유되었다. 저자들은 구개부의 소타액선에서는 아주 드물게 발생하는 호산성 과립세포종에 대하여 진단 및 치료를 시행하고 양호한 결과를 얻었기에 문헌 고찰과 함께 보고하는 바이다. Oncocytes are large, granular, eosinophilic epithelial cells mainly found in many glandular tissue including salivary glands, the thyroid, parathyroid, pituitary, adrenal gland, testicle, fallopian tube, liver and stomach etc. Oncocytoma, which originate from oncocytes are uncommon benign neoplasm that present approximately 1.5% of all salivary gland tumors. They typically occur in parotid gland of elderly patients and rarely in submandibular gland or minor salivary gland. On gross examination, they are usually 3 to 4 ㎝ is size and possess a well-defined capsule. Histologically oncocytoma peculiarly consisted of oncocyte which has cytoplasm, filled with eosinophilic granules on light microscopy and a large number of enlarged and morphologically altered mitochondria by electron microscopy. Oncocytomas are essentially benign tumors and complete excision is recommended. Local recurrence is extremely rare, but when it occurs, it may be multifocal. We report a case of oncocytoma raised from minor salivary gland of palate in 38 years old male patient with literature.

한국어의 의미 분석을 위한 개념 그래프 생성기의 설계

朴仁喆,裵雨正,李鏞碩 全北大學校 1996 論文集 Vol.42 No.-

To generate conceptual graphs for Korean sentences, in this paper, we design the conceptual mapping rules which map each word into concepts and the semantic interpretation rules which are based in Korean sentence patterns to decide conceptual relations. However, the conceptual graphs generated by the semantic interpretation rules semantically are ambiguous because they represent the general conceptual relations between concepts. So, we incrementally build the conceptual patterns which represent semantic restrictions for each word. We, also, design the generator which generates conceptual graphs from the result of syntactic analysis based on the conditional unification.

抗打應力을 考慮한 말뚝과 해머의 組合

박용원,김석훈 명지대학교 공학기술연구소 1993 공학기술연구소 논문집 Vol.8 No.-

In pile driving practice, driving hammer should match well with piles in order to avoid pile dammage due to overdriving or imperfect penetration from insufficient hammer capacity. Some pile-hammer couples recommended in handbooks and manuals are used in pile driving. However, they have not been examined with driving stress and allowable stress of pile in driving practice at field. This study performs calculation of driving stress with wave equation analysis program(WEAP/G) and several pile driving formulae for PC and PHC piles. In calculation, the input data are made to represents the practical conditions at field. As results we recommend pile-hammer couples for PC and PHC piles with diesel hammers. The driving stresses calculated with pile driving formulae show tremendous scatter and therefore using pile driving formulae in driving stress calculation is not recommendable.

朴容石,金東守,金在植 여수대학교 1988 論文集 Vol.2 No.-

The oceanic condition characteristic in the coastal fishing ground of Yeosu is investigated by the oceanographic observation in summer, 1988. The results to analyze the data obtained from this observation are as follows: (1) The coastal surface water accepted influence of land is high temperature and low salinity, and the off shore water and bottom water are low temperature and high salinity. (2) In summer the eddy current and discontinuity appeared in the fishing ground of the set net, so a good catch expected in this fishing ground. (3) In summer the sharp thermocline appeared between the depth of 30m and 40m in coastal fishing ground. This thermocline prevents vertical mixing.
