  • Make-up changes facial images. In particular, eyebrow make-up is a part of changing expression most easily and effectively. While color make-up is helpful to produce women's desired image with their favorite colors, eyebrow make-up is hidden actor to give a clear impression to others. Therefore, this study connected facial type which is an important factor deciding facial image with eyebrow, examined image of eyebrow make-up and that changed by facial types and aimed to be helpful in producing more effective facial image with eyebrow make-up considering one's facial type. Consequently, it was found that eyebrow make-up was a great factor in making better facial impression and image and complementing the weakness of facial type. h strong impression of facial type can be changed into soft shape or foolish shape in worse case depending on the types of eyebrow make-up. Eyebrow make-up shows charming image as angle of eyebrow is steep, heavy image as eyebrow is horizontal, cold image as eyebrow tail rises and simple and dull image as it lowers. Therefore, it is known that image of eyebrow make-up can be governed by several factors including angle and direction of eyebrow. Consequently, it is thought that most effective eyebrow make-up considers individual facial types, images of their eyes, noses and mouths and factors deciding angle, direction and colors of eyebrow.

  • The spermiogenesis of a Korean octopus, Octopus minor, inhabiting western of Korea Sea was observed by electron microscopy . The obtained results are as follows: The spermiogenesis of Octopus miner proceeds through four stages; early- , mid- , and late-spermatid, and mature sperm. An early spermatid is a spherical cell looking light due to the low electron density. The acrosome formed from Golgi complex of the upper nucleus looks dark due to the high electron density. The extra-nuclear rod (enr) stemming from proximal centriole is transformed from round shape into oval shape, elongating to the upper nucleus. In our observation, the axoneme was being formed from distal centriole, and the manchette composed of a number of microtubules is also found around nuclear membrane. In a mid-spermatid, chromatins in the nucleus contract shaping fine threads, and the manchette is also observed around nuclear membrane. Especially, the spherical acrosome is transformed into long oval one which is tinged with a number of horizontal stripes and has the middle electron density. In a late-spermatid, chromatins in the nucleus contract thick and short. Furthermore, the mitochondrial sleeve, in which the axoneme is surrounded with mitochondria, is observed at middle piece. The axoneme has a typical structure of 9+2 and around it, 9 coarse fibers are observed. Also in the acrosome cavity of mature sperm, horizontal striation is found. However, regularly spaced processes are peculiarly observed in there. A sperm is about 390 fm long, whose head is bent a little like a banana while the acrosome region is helical. In the middle piece of sperm, $11\sim12$ mitochondria are surrounding coarse fibers that reach the main piece of tail, while nothing but 9+2 structured axoneme is found in the end piece.

  • In-flight icing is a critical technical issue for aircraft safety and, in particular, ice accretions on aircraft surfaces can drastically impair aerodynamic performances and control authority. In order to investigate icing effects on the aerodynamic characteristics of KC-100 aircraft, a state-of-the-art CFD code, FENSAP-ICE, was used. A main wing section and full configuration of KC-100 aircraft were considered for the icing analysis. Also, shapes of iced area were calculated for the design of anti-/de-icing devices. The iced areas around leading edge of main wing and horizontal tail wing were observed maximum 7.07% and 11.2% of the chord length of wing section, respectively. In case of wind shield, 16.7% of its area turned out to be covered by ice. The lift of KC-100 aircraft were decreased to 64.3%, while the drag was increased to 55.2%.

  • Blades of horizontal axis are nowadays made of composite materials. Generally, composite materials satisfy design provides lower weight and good stiffness, while laminate composites have often damages as like the delamination and cracks at the interface of laminates. The box spar and tail parts of a blade are composed of the CFRP/GFRP hybrid laminate composites. However, delamination and the interfacial crack often occur in the interface of CFRP/GFRP hybrid laminate composites under the mixed mode fracture condition, especially mode I and mode II. Therefore, there is a need for the evaluation of the mixed mode fracture behavior during the delamination of CFRP/GFRP hybrid laminates. This study shows the experimental results for the delamination fracture toughness in CFRP/GFRP hybrid laminate composites. Fracture toughness experiments and estimation are performed by using DMMB(Dissimilar mixed mode bending) specimen. The materials used in the test are a commercial woven type CFRP(Carbon fiber reinforced plastic) prepreg(CF3327) and UD type GFRP(Glass fiber reinforced plastic) prepreg(HD224A). A CFRP/GFRP hybrid laminate composite is composed by the 10 plies CFRP and GFRP prepreg for DMMB. A thickness of CFRP and GFRP layer is 2.5mm and 3.0mm, respectively. Also the fulcrum location which is a loading parameter is changed from 80 to 100mm on the specimen of length 120mm because it defines the ratio of mode I to mode II. In this study, the effects of the fulcrum location are evaluated in the viewpoint of energy release rate in mode I and mode II contribution. The results show that the delamination crack initiates at higher displacement and lower load according to the increase of the fulcrum location ratio. And the variation of the energy release rate for mode I and II contributions for the mode mixity are shown.

  • One of the topics concerning the electromagnetic compatibility of modern electronic circuits is to take protection from transient overvoltages caused by not only cloud-to-ground lightnings but also induced lightning discharges. In this paper, the vertical electric and horizontal magnetic fields from cloud-to-ground lightnings were measured and analyzed. The electric and magnetic fields waveforms associated with cloud-to-ground lightnings have several subsidiary peaks which decrease with time. There were not much differences between the electric and magnetic field due to long distance cloud-to-ground discharges. Average values of 10~90% rise times of electric fields are $4.65mutextrm{s}$ for the positive cloud-to-ground lightning and $3.29mutextrm{s}$ for the negative cloud-to-ground lightning, respectively. Also, in the positive and negative cloud-to-ground lightning discharges, the zero-to-zero crossing times in the wave tail of magnetic fields are significantly longer than those of the electric fields.

  • The mature sperms of three species of cephalopods (Octopus minar, Octopus ocellatus, Todarodes pacificus) were observed by electron microscopy. The results obtained are as follows: The sperm lengths of Octopus minor and Octopus ocellatus of octopods are long and they are about $390{\mu}m$ and $125\sim130{\mu}m$, respectively, but the sperm length of Todarodes pacificus is short and about $35{\mu}m$. The sperm of Octopus minor has a helical acrosome and a head bent a little like a banana while Octopus ocellatus of octopod has a twisted acrosome and a long rod-shaped head. A number of horizontal stripes are observed as a periodic structure in their subacrosome cavities and dense plugs are formed in the cavities of their heads. On the other hand, the acrosome of Todarodes pacificus is circular cap-shaped, and its head is long and oval. It is notable that two small cavities were observed in its basal acrosome. Juxtanuclear acrosomal materials of high electron density filled the subacrosomal cavity. In the middle piece of mature sperms of Octopus minor and Octopus ocellatus, the mitochondria form the mitochondrial sleeve, but the numbers of mitochondria differ between the species so that they are $11\sim12$ and $8\sim9$, respectively. Meanwhile, in the middle piece of mature sperms of Todarodes pacificus, the mitochondria are separated from the axoneme, forming a mitochondrial spur in which $10\sim13$ mitochondria and some electron dense materials concentrate. The axoneme of Octopus minor, Octopus ocellatus and Todarodes pacificus are of 9+2 type in common, surrounded by 9 coarse fibres. A number of glycogen were observed only in the axoneme of Todarodes pacificus. The coarse fibres were found as far as the main piece of sperm tail in Octopks minor and Todarodes pacificus, while to the end piece of sperm tail in Octopus ocellatus.

  • The behavior of conger eel, Astroconger myriaster (Brevoort), to the bamboo and plastic pots with baits was investigated alternately in two experimental water tanks. One of the pots being dropped on the tank bottom, the eels touched it to obtain the bait probably by their sense of smell, and increased rapidly in the number of touch to show a maximum within 30 minutes. But the touch was made mainly to the pot wall at which the bait was located and quite accidentally to the pot mouth. The eels touched the pot mouth retreated frequently without attempting to enter the pot and their entering was very hampered by the bamboo funnel constituting the pot mouth. However, a entering, if made, encouraged other touches and the touches ascribed other enterings. But, if 30 minutes elapsed, the number of touch decreased gradually and so the enterings were little made. The ability of pots attracting the eels into them was varied with their inclination to the tank bottom and the bait position in them. That is, the pot which was laid horizontally showed high ability of attracting in case in which the bait was fixed in the vicinity of its mouth. The pot, inclined by $30^{\circ}$ by lifting its tail and had a bait left free, showed almost equal ability to the horizontal pot with a bait in the vicinity of mouth. But the pot, inclined by $30^{\circ}$ by lifting its mouth and had a bait left free, showed a very low attracting. A comparison between the bamboo and plastic pots gave only that the entering of the eels became later several minutes in the latter.

  • The purpose of this study was to estimate internal motion using molecular sieve for quantitative improvement of lung tumor and to localize lung tumor in the small animal PET image by evaluated data. Internal motion has been demonstrated in small animal lung region by molecular sieve contained radioactive substance. Molecular sieve for internal lung motion target was contained approximately 37 kBq Cu-64. The small animal PET images were obtained from Siemens Inveon scanner using external trigger system (BioVet). SD-Rat PET images were obtained at 60 min post injection of FDG 37 MBq/0.2 mL via tail vein for 20 min. Each line of response in the list-mode data was converted to sinogram gated frames (2~16 bin) by trigger signal obtained from BioVet. The sinogram data was reconstructed using OSEM 2D with 4 iterations. PET images were evaluated with count, SNR, FWHM from ROI drawn in the target region for quantitative tumor analysis. The size of molecular sieve motion target was $1.59{\times}2.50mm$. The reference motion target FWHM of vertical and horizontal was 2.91 mm and 1.43 mm, respectively. The vertical FWHM of static, 4 bin and 8 bin was 3.90 mm, 3.74 mm, and 3.16 mm, respectively. The horizontal FWHM of static, 4 bin and 8 bin was 2.21 mm, 2.06 mm, and 1.60 mm, respectively. Count of static, 4 bin, 8 bin, 12 bin and 16 bin was 4.10, 4.83, 5.59, 5.38, and 5.31, respectively. The SNR of static, 4 bin, 8 bin, 12 bin and 16 bin was 4.18, 4.05, 4.22, 3.89, and 3.58, respectively. The FWHM were improved in accordance with gate number increase. The count and SNR were not proportionately improve with gate number, but shown the highest value in specific bin number. We measured the optimal gate number what minimize the SNR loss and gain improved count when imaging lung tumor in small animal. The internal motion estimation provide localized tumor image and will be a useful method for organ motion prediction modeling without external motion monitoring system.
