摘 要 : 장수허리노린재의 後胚子成長期에 있어서 4個의 觸角節을 對象으로 제1齡 幼 부터 成 에 이르기까지의 길이를 測定하여 Holzinger & Harmann(1941)의 因子分析法과 Park(1977)의 變形法을 적용하여 成長因子를 分析한 結果 다음과 같은 結論을 얻었다: ① 4個의 觸角節은 2個의 成長因子가 區別된다. ②第1因子는 一般因子로소 成長促進因子였고, 第2因子는 群因子로서 作用하였다. ③2種의 因子를 結合해 보면 4個의 觸角節은 成長影響을 달리하는 第1節과 弟4節의 弟1群, 弟2群, 弟3節의 弟3群으로 區別할 수 있었으나 弟3群은 弟2群에 近似하였다. ④弟2節의 共通度가 가장 크고, 弟4節의 共通度가 가장 낮다. ⑤成長因子의 特性은 齡이 進前됨에 따라 增加한다(P<0.05). ⑥ 觸角 弟1節과 弟2節間의 分節과 觸角 弟3節과 弟4節間의 分節의 2個 分節이 先行되고, 觸角 弟2節과 弟3節間의 分節이 二次的으로 行해진다. Applying the Averoid Solution of Factor Analysis of Holzinger & Harmann(1941) and Park's techniques (1977) to the original values for instar in the four antennal segments of A. dallasi, it is summarized as follows: ①All the four antennal segments are found to have the two factors.②The first os acceptable as a general factor and a growth promoting factor, whereas the second factor is indicated as a group factor.③The four segment are classifiable into the three groups- The first group of the first and fourth segments, the second group of the second segment, and the third group, of the third segment. But the third group is similar to the second group in the influence of the factors. ④ The communality of the highest, while that of the fourth segment is the lowest. ⑤ The contribution of the growth factor is increased according to the development of the instars (P<0.05). ⑥ The segmentations between the first and second segments and between the third and fourth segments are precded, and followed by the segmentation between the second and third segments secondarily.

산성수와 소금쟁이(노린재목: 소금쟁이과)의 발육

박상옥 대구효성가톨릭대학교 1998 연구논문집 Vol.57 No.2

소금쟁이를 실험실 (27.50±1.25℃,60±3.5%)에서 산성도를 각각 pH 1.0, pH 3.0, pH 5.0, pH 7.0 및 pH 7.3으로 달리한 인공 산성수에서 사육하였다. pH 1.0과 pH 3.0에서의 난의 부화는 가능했으나, 제 2령 유충으로의 탈피는 불가능했다. pH 5.0에서는 제 3령 유충으로의 탈피가 불가능하였다. 성체의 출현은 pH 7.0에서만 가능하였으며 그 율은 2.3%이었다. 소금쟁이의 생활에 적당한 산성도는 pH 7.0이었다. 유충의 총 발육기간은 pH 7.0에서 29.65일 이었다. 발육단계별 발육기간은 난기가 제 5령 유충기를 제외한 다른 어떤 발육단계보다 길었으며, 그 이외의 발육단계별 발육기간 간에는 차가 없었다. 생존 곡선은 초파리(凸)형 (convex type)이었다. 알의 색깔로서 수질의 pH정도를 추정할 수 있어, pH의 생물학적 추정을 위해 소금쟁이의 알은 생태학적 지표로 활용될 수 있을 것이다. The water strider Gerris paludum insularis (Motschulsky) was reared in laboratory with a temperature of 27.5±1.25℃, humidity of 60±3.5% at five constant acid waters with a pH of 1.0, 3.0, 5.0, 7.0 and 7.3. Eggs hatched, but failed to mlt to the second instar larva in the water with a pH 1.0 and 3.0. The second instar larva failed to develop to the third instar larva in the water with a pH of 5.0. Adult emerged at the rates of 2.3% only in the water with a pH of 7.0. The optimal pH for development and survival was 7.0. The developmental duration in days totaled 29.65 days in the water with a pH of 7.0. The developmental duration of egg was longer than that of other istar larvae except the fifth instar larva. The survivorship curve is convex. The color of developing eggs may be a useful indicator for each of the level of pH.

This study aims at the new pattern drafting of one-piece dress on the basis of changes in the body types and comfort of elderly women. After classifying into four groups according to each back-forms through the body measurement and the shilhouettes of photographys focused on 123 elderly women of 60 to 79 years old, in order to set the measurements demanded of marking the upper graments patterns for elderly women. This study will show an analysis of the body and surface changes by all the actions for producing patterns in each types. And compared the new pattern with conventional patterns through the sensory evaluation. 1. As the result of the physique analysis, the 123 elderly women's body types were generally divided into four types : A type(43%) is a standard type one which is the expansion of back size, B type(22%) is a bent back type, C type(25%) is a half standard type, D type(10%) is a half bent back type. 2. As the result of the measurement of changes in the limb surface caused by the limb movements, so called M4 for length item, which is showed its greatest change. 3. As the result of the pattern drafting and wearing test, A type using the standard item of abdominal length, instead of hip circumference, has 2cm margin in waist and hip circumference. B type has 2.5cm lengthened full length and 2.5cm lowered center back waist length. C type has 0.6cm lowered both standard dart and full length, but 0.6cm lengthened center back waist length. Finally, D type has 1.2cm lengthened center back waist length and 1.2cm lowered full length. 4. As the result of the sensory evaluation for apperarance, it showed the significant difference in 14 items in every type. The new pattern proved superior to the convential patterns. In addition, as a result of the sensory evaluation for comfort, since it showed the significant difference in movements and body parts the new pattern proved also superior to the conventional pattern.

A study was performed to investigate the effect of electrical stimulation on disused and denervated rat skeletal muscle(soleus). The microstructural changes on soleus were examined with electron microscope(Transmission Electron Microscope). The results are summarized as follows. First, Photomicrographs of soleus muscle in casting treated rat are convolution of Z-line and Myofilaments, and absence of M-line in some A-band. There are some vacuoles in A-band, I-band and A-I junction. Second, also indentation of nuclear membrane, the absence of sarcolemma(arrow), and the convolted myofilaments. Third, the soleus in electrical stimulated rat after casting are increased aspect of sarcosomes. Fourth, also the repaired aspect of basal lamina in sarcolemma(allow). Fifth, Denervated soleus are severe atrophic changed, also cannot finded any structural changed. These results indicate that the electrical strmulation effected on soleus, delayed of muscular atrophy on disused muscle atrophy.

The present study aims at the analysis of the rise of business houses and economic concentration in India. The causes of concentration of economic power in the hands of a few business groups in Indian industries are various. Primarily these are to be found in the nature and distribution of entrepreneurship among the India people. Also important are the historical and other forces which did not allow the growth of a proper climate of enterprise in India. The concept of 'Business House' in India, for a long time, continued to be equated with a 'Managing Agency House'. Factors behind the rise of business house can be divided in this study into three broad categories. In the first category are placed the factors that have had their origin in the problems of entrepreneurial growth in India, its nature and regional distribution. From the very beginning up to this date entrepreneurial activities in the fields of industry and trade have been concentrated in certain religious and regional groups like the Marwaris, Parsis and the Gujaraties. This regional and commercial concentration of economic power is an extremely important sociological phenomenon which cannot be ignored in India condition. In the second category are placed the factors that have their roots in the shortage of venture capital and finance in the country in the colonial context. The nature of industrial finance in India, the difficulties faced by the new entrepreneurs in securing the necessary finance for their project are to be considered here. In the third category includes the factors which owe their origin to the economic policies of the state. The role of the state after independence in promoting private business and concentration of economic power is also important factor. It is hoped that the present work may contribute to a proper understanding of the complex problem of business houses and concentration of economic power in India.

벌집부채명나방, Achroia grisella(Fabricius)수컷의 소리에 대한 암컷의 반응(곤충강, 나비목, 명나방과)

朴商玉 대구효성가톨릭대학교 1992 연구논문집 Vol.45 No.1

The response and orientation of virgin females the lesser wax moth, Achroia grisella(Fabricius) (Pyrallidae, Galleriinae) immediately after eclosion toward male sounds for pair formation were tested under various operational conditions. There are three types of no response, a stray and a orientation moths in the approaches of female toward stationary wing-fanning or circling male. There are significant differences in the approach behaviours and orientations of female moths removed antenna(e) and tympanum(a) toward the ultrasound emitter and male removed tegula. The approaching rates of female toward male in a short distance were higher and faster than in a long distance. Females removed the left antenna may directly contact fast the intact male than female punctured the right tympanum. No females punctured tympana approach toward intact male in a long distance, the immediate outside of the screen arena. The pheromone released from the male's wing glands may stimulate kinesis in females, it does not elicit orientation, while the calling sound induces virgin female to orient toward males.

풍화작용에 의한 정상모발의 형태학적 변화

홍완성,장병수,임도선,박상옥,여성문 韓國電子顯微鏡學會 2000 Applied microscopy Vol.30 No.1

성인 남성의 모발에서 정상 모간과 자연상태에서 손상된 모간의 외부형태와 미세구조적 변화를 광학현미경과 주사 및 투과전자현미경으로 관찰하였다. 정상 모간은 모소피층, 모피질, 모수질 등의 3부분으로 구성되어 있었다. 모소피층은 5-7개의 모소피세포들이 중첩되어 모피질과 모수질을 둘러싸고 있고, 길게 신장되어 모피질을 둘러싸고 있는 소피세포의 두께는 약 0.4㎛로 확인되었다. 또한, 이들 세포사이에는 약 25㎛의 세포사이 막복합체가 관찰되었다. 모피질은 잘 발달되어 각질화세포(cornified cell)들로 치밀하게 채워져 있었고, 각질화세포는 직경 약 0.5-0.8㎛인 구형 또는 타원형외 macrofibril로 구성되어 있었으며, 이들은 약 8nm 두께의 가는 microfibri이 동심원상의 규칙적인 형태로 배열되어 있었다. 그리고 macrofibril 사이에는 약 0.5㎛크기의 직경을 가진 구형의 melanin과립들이 고르게 산재되어 관찰되었다. 모수질은 공기가 채워져 있었고, 직경이 약 16㎛의 구형의 형태로 모간의 전체 직경에 1/5 정도를 차지하고 있었다. 풍화에 의해 손상된 모간은 모소피층이 박리되어 있었으며, 모피질세포의 세포질도 손상되어 melanin과립들이 표면에 노출되어 있는 것이 확인되었다. 조직표본상에서 모소피층의 박리과정은 모소피 사이에 공포가 형성되고, 이어서 모소피의 가장자리가 떨어져 나가고, 박리되지 않은 부위는 절단되었다. 모소피가 탈락되어 모피질이 노출된 부위에서는 각질화세포내에 존재하는 macrofibri이 각각 분리되고, 인접원 macrofibril 사이에 공기가 채워지게 되어 오간의 풍화과정은 더욱 촉진되었다. 그리고 노출된 macrofibril 사이에서 탈락 직전의 melanin 과립들이 산재되어 관찰되었다. The morphological changes in normal and weathering hair shafts of the human scalp were investigated by using the transmission and scanning electron microscopes. The hair shaft composed of cuticular layer, cortex and medulla. The surface of normal hairs are smooth and covered by imbricated cuticular scales. The cuticular layer consists of five to seven cuticle cells. These cells, which are flat and thin, measuring about 100 ㎛ long and 0.4 ㎛ thick, appears intercellular membrane complex in diameter 25 nm. The cortex composed of melanin granules and cornified cells, which multicomponent concentric microfibrils in diameter about 8 nm give rise to macrofibrils in diameter 0.5 ㎛ to 0.8 ㎛ encased in limiting membrane. The melanin granules are spherical shaped about 0.5 ㎛ in size and scattered between macrofibrils. The medulla in the normal hairs are 16 ㎛ in diameter centrally region of cortex. Normal hair shafts undergo progressive degenerative changes due to a variety of environmental insults. In the initial weathering process of hair, the cuticular scales became irregularly raised and broken, and then cuticle cells formed cytoplasmic vacuolation, following dissociated intercellular membrane complex, ultimately entirely lost and nuded cortex. Occasionally, transverse fissures were seen at hair shafts indicating that the hairs were deteriorated Complete removal of the cuticular layer in the heavily damaged cortex portions appeared splitting of the cortical cell into its macrofibrils and scattering of melanin granules.
