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.

Elevational Distribution of Breeding Bird Communities in Seoraksan National Park, Korea

Hwang, Hyun-Su,Lee, Jae-Kang,Eom, Tae-Kyung,Bae, Ho-Kyoung,Lee, Dong-Ho,Lim, Jong-Hwan,Jung, Sung-Cheol,Park, Chan-Ryul,Rhim, Shin-Jae Korean Society of Forest Science 2020 한국산림과학회지 Vol.109 No.1

In this study, the elevational distribution of breeding birds in Seoraksan National Park, Korea was investigated. Forty-six species of birds were documented from line transect surveys taken from Seorakdong at 230 m above sea level (a.s.l.) to the Daechungbong summit at 1708 m asl. Birdspecies richness and diversity were highest in Seorakdong and lowest at the Daechungbong summit. As elevation increased, bird species richness and diversity decreased, with a humped-shape trend being observed between 700 m and 1200 m a.s.l. Stepwise analyses revealed that breeding bird species diversity indices were significantly negatively correlated with elevation (r² = 0.327, P < 0.001) and positively correlated with vegetational coverage (r² = 0.324, P = 0.046). Higher elevations supported fewer birds than low and intermediate elevations. Projections at the local scale, including data on behavior and habitat use by birds, will be necessary for optimal conservation and management of the bird communities in Seoraksan National Park.

이정숙,정민철,김우식,이근철,김홍중,박찬선,이헌주,주윤정,이근종,안종석,박완,박용하,민태익 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

肝臟疾患에 있어서 血淸鐵値 變動에 關한 臨床的 硏究

朴贊鍾,高侊道 고려대학교 의과대학 1972 고려대 의대 잡지 Vol.9 No.1

On the patients of liver diseases who had been admitted to the Gastroenterology of this hospital, the serum iron levels was determined in 221 patients from whom they were subdivided into 88 cases of infectious hepatitis (48 cases of acute hepatitis and 40 cases of chronic hepatitis), 99 cases of postnecrotic liver cirrhosis, and 34 cases of primary hepatoma. The relationships between the serum iron level and the liver function tests, such as A/G ratio, total bilirubin, alkaline phosphatase activities, transaminase activities, total cholesterol levels with its ester form(%) and thymol turbidity tests according to the kinds of liver diseases were observed. The results were as following. 1. Of liver diseases, in cases of the primary hepatomas, the serum iron levels was remarkably decreased to 84.0 rg./dl. compared with the normal value 136.9 rg./dl. and postnecrotic liver cirrhosis showed the values 144.0 rg./dl. closely resembled to normal values. Infectious hepatitis showed the more increase of iron level than normal. Namely, acute case was 158.7 rg./dl. and chronic case was 186.0 rg./dl. 2. In the primary hepatomas, in addition to the remarkable decrease of serum iron level, reversed A/G ratio, the increases of total bilirubin, alkaline phosphatase activities and transaminase activities, increase of total cholesterol with its ester form(%) decreased and the increase of thymol turbidity tests were also noted. 3. However, is the acute infectious hepatitis, another with the primary hepatomas, the tendency of increases of alkaline phosphatase activities, transaminase activities, total cholesterol and thymol turbidity tests were observed as well as the increase of serum iron level. 4. And the correlations between the significant abnormal findings of liver function tests and the serum iron levels were not noticed in cases of liver cirrhosis and the chronic infectious hepatitis. 5. Such relations suggest the abnormal findings of liver function tests do not keep pace with the variety of serum iron level but occurs differently according to the lesions of liver diseases themselves. And that serum iron level might be helpful for the differential diagnosis between primary hepatoma and other liver diseases.

The purpose of this study is to obtain basic infotmation on the wettability of pure-Al/Al₂O₃, Al-alloy/Cu, Al-alloy/Ni and Al-12%Si/Al₂O₃systems, by using the Sessile drop method. The wettability of Al alloy-melt on Al₂O₃increases with increasing temperature from 750℃ to 850℃ for Al-12%Si-y% (Cu, Zn and Mg) (y:0∼2)/Al₂O₃system, the contact angle decreases with increasing Cu, Zn and Mg content. The wettability of Al alloy on Cu and Ni-palte is better than that on Al₂O₃-plate : this is attributed to the interfacial reaction between the Al aiioy and the metal substrate.

The purpose of this study was to estimate physique and muscular strength in collegiate athletes. On a sample of 70 athletes (basketball, baseball, soccer, and ice-hockey) anthropometric measurements (height, weight, bone width, circumference and skinfold thicknesses) were taken, For the measurements of muscular strength grip strength, back strength, arm flexion and leg extension strength were tested. The results of this study showed that basketball players were highest for height, weight, humorous and femur diameters, chest circumference, and calf circumference. Ice-hockey players were highest for upper arm and flexed upper arm circumferences. On the other hand ice-hockey players were lowest for height, soccer players for weight, baseball players for humerous and femur diameters, soccer players for chest circumference. For skinfold thickness baseball players (10.1mm) were highest for triceps, basketball players (14.5mm) for subscapular, ice-hockey players (13.3mm) for suprailiac and medial calf (9.0mm) skinfold thicknesses. While soccer players were lowest for triceps (8.7mm), subscapular (8.6mm), suprailiac (9.8mm) and medial calf (7.5mm) skinfold thicknesses. There were significant differences (P〈0.01) for height, weight, femur diameter, upper arm and flexed upper arm circumferences among athletes. Grip strength (left and right) was highest in baseball players (52.1kg, 50.8kg) but lowest for soccer players (42.3kg, 42.8kg). Baseball players were highest for back strength (162.0kg). On the other hand back strength was lowest in ice-hockey players (127.1kg). For arm flexion and leg extension strength (left, right) basketball players (42.0kg, 44.9kg) were highest for both strength tests. While soccer players were lowest for arm flexion strength and baseball players for leg extension strength. Ice-hockey players were highest for sit-up (59.2). Significant differences (P〈0.01) were found for grip, back, arm flexion and leg extension strength and sit-up among athletes.

Silicon diaphragm arrays were fabricated by silicon micromachining using porous silicon. Fabricated diaphragms consist of 3x3 array. The thickness of diaphragm is 5μm and theire size are 200x200, 300X300 and 400X400μm^(2), respectively. Several % of resistance change is observed, when stress was applied at diffused resistor on the diaphragm. Microdiaphragm arrays were easily fabricated by silicon micromachining using porous silicon, and we confirmed feasibilty of application at tactile sensor.
