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.

In a case of driving beginnners, it is very difficult to park a car perfectly because driver's knowledge makes more errors than intelligent mechanism when they are performed repeatedly. However skilled drivers be of experienced knowledge are able to park a car quickly. In this paper, we analyzed driving patterns of skilled drivers, designed the fuzzy controller to park based on it, and perform auto-parking simulation of a car using that controller.

H₂-공기와 CO-공기 예혼합 화염 사이의 후류상호작용에 있어서 H₂O 첨가 효과

박정(Jeong Park),권오붕(Oh Boong Kwon),김태형(Tae Hyung Kim),박종호(Jong Ho Park) 한국연소학회 2015 한국연소학회지 Vol.20 No.1

Numerical study was conducted to clarify effects of added H₂O for the downstream interaction between H₂-air and CO-air premixed flames in counterflow configuration. The reaction mechanism adopted was Davis model which had been known to be well in agreement with reliable experimental data. The results showed that both lean and rich flammable limits were reduced in increase of strain rate. The most discernible difference between the two with and without having H₂O and/or H₂ addition into H₂-air and CO-air premixtures was two flammable islands for the former and one island for the latter at high strain flame conditions. Even a small amount of H₂, in which H₂-air premixed flame cannot be sustained by itself, participates in CO oxidation, thereby altering the CO-oxidation reaction path from the main reaction route CO + O₂ → CO₂ + O with a very long chemical time in CO-air flame to the OH-related reaction routes including CO + OH → CO₂ + H with very short chemical times. This intrinsic nature alters flame stability maps appreciably. The results also showed that chemical effects of added H₂O help lean flames at relatively low strain rate be sustained, and suppress the flame stabilization at high strain rates.

본 연구는 경주지역 1개 고등학교 3학년 여고생을 대상으로 초경 시작 전인 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레 수치와 초경 연령을 파악하여 여성의 초경이 빠를수록 체성장 속도의 변화가 있을 것이라는 가설을 기초로 두 요인간의 관련성을 파악하고자 시행되었다. 경주시 1개 여자고등학교 3학년생 총 317명에 대해 ㅊ경 나이, 초경시 심리 상태, 초경이 시작되었을 때의 상담 여부와 상담하였던 사람, 부모 신장과 초경전후의 식사 규칙성, 다이어트 경험, 수면시간, 스트레스, 음주/흡연 여부, 질병력 등에 대한 설문 조사를 시행하였고, 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레에 대한 정보는 건강기록부에서 확보하였다. 상기 대상자 중 건강기록부가 분실된 39명, 초경나이에 대해 응답하지 않았던 29명 및 결석 등으로 조사를 하지 못하였던 42명을 제외한 조사 대상자는 206명으로 선정하였다. 대상자들의 초경연령 평균값(Mean±SD)은 13.0±1.11이었고, 초등학교 4학년부터 고등학교 2학년까지의 초경 이후 신장 성장률은 감소하였으며, 초경연령이 빠른 군이 초등학교 때는 신장에 있어서 우위를 차지하나 고등학교에 오면서 신장은 비슷한 수준이 되었다. 초경후 1-2년 사이에 체중과 흉위의 증가율은 감소하였고, 초경연령이 빠른 군이 초등학교와 고등학교 사이에 체중과 흉위에서 모두 우위를 차지하였다. 본 연구의 결과는, 흔히 이차 성징의 시작 시점 혹은 사춘기의 시작 시점으로 보고있는 초경 연령이 청소년기의 성장과 밀접한 관련성이 있고, 특히 체중과 흉위의 성장 속도와 밀접한 관련성이 있음을 시사한다. To understand the onset of menarche in relation to changes in physical growth that take place during female adolescence, especially the changes in height and weight velocity. The 207 senior in one women high school of Kyongju were investigated in April 3 to 8, 2001. We collected the information, relation in the age at menarche, height & weight of parents, regularity of eating, and obesity diet, duration of sleeping, sickness & stress near age at menarche, by self-recording. The status of height, weight & chest circumference between the 4th grade of primary school and the junior of high school was collected by individual Health Record. The results were followed; The average age at menarche was 12.95±1.11 years old and the most frequent age of menarche is 13 years. After menarche, the velocity of height, weight and chest circumference were decreased. The most rapid group of menarche hold dominant position in height during elementary school. As time passed, they dont hold dominant position in height. The most rapid group of menarche get an advantage in the weight and the girth of chest after elementary school. The height of subjects is directly proportional to the height of their parents. These results suggest that the starting age at menestuation can be closely associated with physical growth and development.

Numerical study was conducted to clarify effects of added $H_2O$ for the downstream interaction between $H_2$-air and CO-air premixed flames in counterflow configuration. The reaction mechanism adopted was Davis model which had been known to be well in agreement with reliable experimental data. The results showed that both lean and rich flammable limits were reduced in increase of strain rate. The most discernible difference between the two with and without having $H_2O$ and/or $H_2$ addition into $H_2$-air and CO-air premixtures was two flammable islands for the former and one island for the latter at high strain flame conditions. Even a small amount of $H_2$, in which $H_2$-air premixed flame cannot be sustained by itself, participates in CO oxidation, thereby altering the CO-oxidation reaction path from the main reaction route $CO+O_2{\rightarrow}CO_2+O$ with a very long chemical time in CO-air flame to the OH-related reaction routes including $CO+OH{\rightarrow}CO_2+H$ with very short chemical times. This intrinsic nature alters flame stability maps appreciably. The results also showed that chemical effects of added $H_2O$ help lean flames at relatively low strain rate be sustained, and suppress the flame stabilization at high strain rates.

The purpose of this study was to assess the soft tissue changes of upper lip & nose using 38 patients who treated with Le Fort I osteotomy for the correction of dentofacial deformities. Patients were devided into three groups. One was advancement group of maxilla(Group I, N= 14), another was impaction group of maxilla(Group II, N= 12) and the other was combination group(advancement & impaction) (Group III, N= 12). Preop. and 1 month postop. (T1), preop. and 6 months postop. (T2) were analyzed and compared. The results obtained were as follows ; 1.The upper lip thickness(UL-VP) moved anteriorly approximately 62% of the horizontal maxillary change and this was significant in the advancement group(Group I) 2.The upper lip length(Stm-Sn) and the lower border of upper lip(Stm) moved superiorly 25%, 40% of the maxillary impaction group(Group II) (P<0.05) 3.There was significancy in the upper lip thicness(UL-VP) approximately 56% of the combination group(Group III) (P<0.05) 4.The nasolabial angle decreased in all groups, but there were no significancy.

The possibility of the correlation and the prediction of vapor-liquid equilibrium(VLE) data by using the relative volatility was analysed. This analysis was carried out for the two different binary groups. The one is for the same binary systems which VLE data were determined at different pressure, and the other is for the different binary systems, one of which component have the same functional group, at the same pressure. The VLE data have been recalculated using a relative volatility which was derived in this work for 18 binary systems and compared with the literature values. The result of the comparison showed a rare possibility of correlation and prediction of the VLE data.

글루타민酸 醱酵副産液을 原料로 한 有機質 複合肥料의 製造

吳旺根,朴鍾河 서울市立大學校 1984 論文集 Vol.18 No.-

Glutamic Acid Fermentation By-product liquid (GAFBL) contains high nitrogen (4.0 %) and organic matter (31 %) so that it could be used as a source of organic compound fertilizer. A large quantity of moisture (62.3 %) in the GAFBL requires a great deal of energy in the process of concentration and dehydration of the material. This work aimed at solidifying the GAFBL with the heat evolved when the GAFBL was treated with concentrated sulfuric acid (88.8 %), fused phosphate (P?O? : 16.1 %) and ammonia (Anhydride) respectively during the period of material processings. Results obtained are as follows: 1. The heavier the acidulation of the GAFBL, the greater the removal of moisture from the GAFBL. The rate of moisture evaporation, however, grew in curvature form as the acidulation became heavier. 2. Mixing fused phosphate to the acidulated GAFBL also reduced moisture content of the latter and solidified it when the mixing rate of the fused phosphate was increased. 3. Ammoniation of the friable mixture of acidulated GAFBL and fused phosphate brought further dehydration of the product. Total evaporation of moisture at above mentioned three successive processing stages ranged 16.5% to 23.6% against the sum of the water in GAFBL and sulfuric acid. 4. The minimum requirement of sulfuric acid (88.8%) and fused phosphate for the solidification of 10ml GAFBL were 2ml and 4g respectively. The final compounds which were ammonified after the solidification showed less than pH=6.5 and contained 5.6% total nitrogen and 2.10% soluble phosphate in weak acid, amounting about 9% in it's total available plant nutrients. The requirement of GAFBL, 88.8% sulfuric acid, and fused phosphate for the manufacture of one ton of such solid compound were 660kg, 200kg and 220kg respectively.
