청소년들의 체격과 체력의 상관성에 관한 연구 : 실업계 고등학교 학생들을 대상으로 Concentrated on Vocational High School Students
조용철,안자희 龍仁大學校 體育科學硏究所 1996 體育科學硏究論叢 Vol.6 No.1
Physique growth is indebted to the nourishment condition, better circumstances, the increased leisure time, owing to the national economy growth. On this back ground "How has the physique been advanced?" "How has the physique influenced the physical fitness?" To prove those questions mentioned above, I measured mainly physique conditions ranged body-weight ration, chest-circumference ration, and sitting height ratio among every other 360 students attending vocational high school. The subject per (15 of age : 120 members 16 of age : 120 members, 17 of age : 120 members ). Thereafter having combined and compared S. Y. Technical High school students with S. K. Commercial High School students. How the physique has been correlated with physical fitness may be summarized as follows: 1. In comparison with physique during last 15 years. Figure shows vast growth in height by 5.48 cm, weight by 2.87 kg, on the contrary, the circumference of the chest has little increase in its size. 2. In comparison physique with physical fitness in vocational high school students. It resulted in as follows. 1) In case of age 15-16, physique and physical fitness of S. K. Commercial High School have wholly prevailed over those of S. Y. Technical High School students, on the other hand at th age of 17 Technical High School students have shown to be predominant. 2) In body-weight ration, there was no difference between the two high school students. 3) In time chest-circumference ratio, S. K. Commercial High School was superior to S. Y. Technical High School. 4) In item sitting-height ratio, S. Y. Technical High School students have shown superiority to those of S. K. Commercial High School students. 3. Correlation between physique and physical fitness item. 1) The order of items that have been influenced from correlation between body-weight ratio and physical fitness item goes as follows; softball throwing ( 0.33 ) 〉100 meter run ( -0.26 ) 〉 physical marks ( 0.23 ) 〉 standing-board jump ( 0.21 ), Other items except for sit-up and pull-up have shown a little correlation. They have shown high significance at the degree P〈.01. 2) the correlation order between chest circumference ratio and physical fitness items shows as follows; 100 meter run ( 0.23 ) 〉 softball throwing ( 0.17 ) 〉 pull-up (0.17 ) 〉 physical marks ( 0.16 ) 〉standing-board jump ( 0.14 ). They have shown significance to the extent of P〈 .05. 3) the degree of correlation between sitting-weight ratio and physical fitness items has shown light correlation in item standing-board jump, but has no correlation among items.

김희민(Hui Min Kim),박관수(Gwan Soo Park),노용우(Yong Woo Rho),유휘룡(Hui Ryong Yoo),조성호(Sung Ho Cho),김동규(Dong Kyu Kim),구성자(Sung Ja Koo) 한국자기학회 2012 韓國磁氣學會誌 Vol.22 No.2
From among the NDT (Non-Destructive Testing) methods, the MFL (Magnetic Flux Leakage) PIG (Pipeline Inspection Gauge) is especially suitable for testing pipelines because the pipeline has high magnetic permeability. MFL PIG showed high performance in detecting the metal loss and corrosions. However, MFL PIG is difficult to detect the crack which occured by exterior-interior pressure difference in pipelines and the shape of crack is very long and narrow. Therefore, the new PIG is needed to be researched and developed for detecting the cracks. The CMFL (Circumferential MF) PIG performs magnetic fields circumferentially and can maximize the magnetic flux leakage at the cracks. In this paper, CMFL PIG is designed and the distribution of the magnetic fields is analyzed by using 3 dimensional nonlinear finite element method (FEM). By Simulating and Measuring the magnetic leakage field, it is possible to detect of axial cracks in the pipeline.

조선 후기에는 소설의 여러 유형중 장편소설, 영웅소설, 애정소설, 가정소설, 판소리계 소설뿐만 아니라 중국의 연의소설, 신마소설 등 수많은 소설들이 유행했다. 이 유형들은 서로 영향을 주고받으며 조선후기 소설사를 풍요롭게 하였다. 『남정팔난기』는 영웅의 이야기가 서사의 골간을 이루고 있다. 이는 영웅의 고난과 그 극복이 극대화되어 그려진다.『남정팔난기』의 구조의 특징은 장편에 상응하는 작품의 길이라는 점, 복수영웅이 등장하고 있다는 점, 군담이 반복 된다는 점에서는 반복적 구성의 특징과 유사하다. 그러나 『남정팔난기』는 ‘오호 쌍연’ 이라는 복수영웅들이 각기개성화 된다는 점, 개성화는 군담을 배경으로 한 다양한 삽화의 활용으로 개인별 역할과 위치가 지워진다는 점이 있다. 그래서 이들이 작품 안에서 이탈하여 개별적으로 존재하더라도 독립적인 영웅소설의 주인공이 될 수 있었음을 알 수 있었다. 이 점은『남정팔난기』만의 특징이다. 그러므로『남정팔난기』는 반복적 구조을 탈피하고 있는 모습을 보여주는 작품이라 하겠다. 동시에 복수(複數)영웅의 이야기로 이루어져 있으면서 황극을 중심으로 하는 일대기적 구조을 지향하고 있다. 또한,『남정팔난기』의 ‘영웅’들은 영웅소설의 영웅에서 보이는 영웅형상화 방식과 변별된다. 첫째, 다섯 명의 남성 영웅들이 등장하고 이들이 각각 영웅으로 형상화 된다는 점에서 특징적이다. 둘째, 여성영웅의 활약이 두드러진다. 두 명의 여성은 모사로서 그들의 영웅성을 발휘하고 있다.『남정팔난기』는 전장에서의 여성의 활약을 용인하고 그들을 긍정적으로 여성영웅으로 묘사하되 이들을 한 인물로 형상화하지 않고 분화시켜 두 여성영웅으로 형상화 했다. 요컨대,『남정팔난기』를 대상으로 그것이 지닌 영웅성의 의미를 밝히기 위해 영웅성의 발현과 구조의 특징을 고찰해 보았다. 이는 『남정팔난기』의 독자적 면모를 구명(究明)하는 동시에 향유층들의 미의식에 대한 이해를 가능하게 할 것이며 『남정팔난기』의 영웅성의 의미를 밝히는데 도움이 될 것이다. In the late of Joseon Dynasty, many novels such as not only full-length novels, hero novels, romantic stories, family stories, pansori stories but also historical fictions and magician stories of China caught on. These stories mutually enriched the novelistic world of the late of Joseon Dynasty by mutually affecting and being affected. In『Namjeongpalnangi』, the story of heroes forms the substance of narration. Also, the hardship and conquest of them is maximized in this story. The characteristics of structure in 『Namjeongpalnangi』are the way of this story corresponding to a full-length novel, the appearance of avenging heroes and the repetition of heroic exploits, also these are similar to the ones of repetitive structure. But, in this story, several heroes ``Oho Ssangyeon`` respectively individualize. This individualization takes away the role and position of an individual by using various illustrations based on heroin exploits. Though the characters make excursions from this story and are individually existing, they can become independent main characters in this hero novel. This is the characteristic in only『Namjeongpalnangi』. Therefore, this novel breaks from the repetitive structure. Also simultaneously, this novel is composed of stories about several heroes and supports the biographical structure based on Hwanggeuk(law books). In addition, with respect to the ``heroes`` of 『Namjeongpalnangi』, the methods forming as a hero are different from the ones in other hero novels. First, there are 5 heroes and they are given form to an individual hero. Second, the heroines have really stood out. These two women show their heroism as a schemer. In this story, the activities of women during the war are accepted and they are positively described as a heroine. Moreover, they are not given form to a character, but to two heroines as dividing. In conclusion, I examined the characteristic of structures in 『Namjeongpalnangi』and the manifestation of heroism for finding the meaning of heroism focused on『Namjeongpalnang i』. This has the purpose to state the independent characteristics of『Namjeongpalnangi』, to make us possible to understand the aesthetic sense of class with power and to find the meaning of heroism in『Namjeongpalnangi』.

Kim, Hui Min,Yoo, Hui Ryong,Cho, Sung Ho,Kim, Dong Kyu,Koo, Sung Ja,Park, Gwan Soo Journal of International Conference on Electrical 2013 Journal of international Conference on Electrical Vol.2 No.4
A defect which is axially oriented with small size is hard to detect in conventional system. CMFL(Cricumferential Magnetic Flus Leakage) type PIG(Pipelines Inspection Gauge) in the NDT(Nondestructive Testing), is operated to detect this defect called axially oriented cracks in the pipe. It is necessary to decompose the size and shapes of cracks for the manintenance of underground pipelines. This article is focused on the decomposing method of the size and shape of the axially oriented cracks by using inspection signal data for defect.

The purpose of this study was to make a comparative analysis of existing dictionaries to find out what problems they faced in terms of related vocabularies, part of microstructure. And it's also meant to make a definition of a 'related word' to provide accurate information on the mean relations of entries, and the types of related words were classified. There were mixed pieces of information on 〈reference words〉 and 〈related words〉 in dictionaries about not only mean relation but grammatical and other relations. So they lacked system and made it difficult to grasp precise mean relation. In this study, a 'related word' was understood as a word that has a hierarchical, partial or complete inclusion relation with an original word, or that has a coordinate relation to an original word within the same category. And I made a definition of inclusion relation and coordinate relation, and classified 'related words' of those relations into subcategories on that base. As for inclusion relation, there were three types of related words that respectively signify hierarchical, partial and complete relations, and concerning coordinate relation, there were two types of related words that respectively represent discriminating and non- discriminating relations.

In this study, organic material removal and the settleability of granular sludge on operating conditions were investigated. The removal rate of SS and COD reached to 95% and 87% respectively at recycle rate of 100, HRT of 2.1hr and organic loading rate of 0.9 ㎏/㎥·day. The COD removal rate of granular sludge linearly increased with the increase of the influent COD concentration. As compared to activated sludge flocs, aerobic granulation significantly improves the settleability of sludge. so the SVI decreased from initial 220㎎/L to 59㎎/L. Low pH and high DO concentration lead to the formation of stable aerobic granules in aerobic upflow reactor. During the early stages of granule formation, a high exopolymer production was observed, which would promote the initial cell flocs. It was concluded that the advantages of aerobic granules can be seen as good settling ability, high retainable biomass concentration and ability to withstand high organic loading rate.
