This paper examines the characteristics of post-modern self-portrait photography. Characteristics of postmodernism associated with the "loss of centeredness," such as the death of the author, interdisciplinarity, and intertextuality, brought about a number of changes within the self-portrait. The distinction between post-modern and modern self-portraiture can be characterized by the following qualities: appropriation, the use of photography, and the utilization of the human body as an art. The characteristics of post-modern self-portrait photography can be represented through the works of Cindy Sherman, Orlan, and Morimura Yasumasa. By presenting prototypical women in her works, Cindy Sherman not only represents images of those women, but also exposes her fictitious role in the work. She creates a distance between herself in the works and herself in reality and discloses a paternalistic gaze. Meanwhile, Orlan transforms her face into a distorted image and presents it as an alternative identity that is representative of postmodernism. She corrodes the standard concept of identity through plastic surgery and treats the face not as a place where the identity stays, but as a simple body part or fragment of skin. Orlan's post-human face is malleable according to the artist's desire to raise the issue of what the human face is, and opposes the structure of modernism. Morimura Yasumasa also appropriates images from masterpieces and presents a hybrid identity between Eastern and Western, male and female, original and replica, and subject and object. In order to dissect social prejudice, he puts forth every single structural dichotomy that coexists in his self-portrait and suppresses a strong ego. He also studies the relationship between 'seeing' and being 'seen' by trading the painter's role from that of the subject to that of the object.

A technique is presented to extract differential second harmonic output from common source nodes of a cross-coupled P-& N-FET oscillator. Provided the impedances at the common source nodes are optimized and the fundamental swing at the VCO core stays in a proper mode, it is found that the amplitude and phase errors can be kept within $0{\sim}1.6dB$ and $+2.2^{\circ}{\sim}-5.6^{\circ}$, respectively, over all process/temperature/voltage corners. Moreover, an impedance-tuning circuit is proposed to compensate any unexpectedly high errors on the differential signal output. A Prototype 5-GHz VCO with a 2.5-Hz LC resonator is implemented in $0.18-{\mu}m$ CMOS. The error signal between the differential outputs has been measured to be as low as -70 dBm with the aid of the tuning circuit. It implies the push-push outputs are satisfactorily differential with the amplitude and phase errors well less than 0.34 dB and $1^{\circ}$, respectively.

If a dangerous situation arises in a place where out of reach from the human, UAVs can be used to determine the size and location of the situation to reduce the further damage. With this in mind, this paper sets the minimum value of the roll, pitch, and yaw using beta flight to detect the UAV's smooth hovering, integration, and derivative (PID) values to ensure that the UAV stays horizontal, minimizing errors for safe hovering, and the camera uses Open CV to install the Raspberry Pi program and then HSV (color, saturation, Brightness) using the color palette, the filter is black and white except for the red color, which is the closest to the fire we want, so that the UAV detects the image in the air in real time. Finally, it was confirmed that hovering was possible at a height of 0.5 to 5m, and red color recognition was possible at a distance of 5cm and at a distance of 5m.

In the present image processing technique, the concept of the gradient indicator(GI) has been introduced to find out the depth-of-field in sizing large particles ranging from $30{\mu}m$ to $30{\mu}m$ where using of the concept of the normalized contrast value(VC) is not appropriate. The gradient indicator is defined as the ratio of the local value to the maximum possible value of the gray-level gradient in an image frame. The gradient indicator decreases with the increases of the particle size and the distance from the exact focal plane. A particle is considered to be in focus when the value of the gradient indicator at its image boundary stays above a critical value. This critical gradient indicator($GI_{critical}$) is defined as the maximum gradient indicator($GI_{max}$) subtracted by a constant ${\Delta}GI$ which is to account for the particle-size effect. In the present ca.so, the value of ${\Delta}GI$ was set to 0.28 to keep the standard deviation of the measured particles mostly within 0.1. It was also confirmed that, to find the depth-of-field for small particles(${\leq}30{\mu}m$) with the same measurement accuracy, tho concept of the critical normalized contrast($VC_{critical}$) is applicable with 85% of the maximum normalized contrast value($VC_{max}$). Finally, the depth-of-field was checked for the size range between $10{\mu}m$ and $300{\mu}m$ when the both in-focus criteria ($GI_{critical}$ and $VC_{critical}$) were adopted. The change of the depth-of-field with the particle size shows good linearity in both the VC-applicable and the GI-applicable ranges with a reasonable accuracy.

For many years, there have been many researches and guidelines to improve the employment rate of discharged soldiers. However, there have not been enough effective analysis conducted about the outplacement service and improvement guidelines. That is the reason why the satisfaction level of governmental supporting programs for the discharged soldiers stays at low level. Therefore, a methodical approach is needed for the discharged soldiers who have dedicated their services for many years for the sake of the country's security. For this reason, tools which can support build an effective outplacement service for the discharged soldiers are required. In this study, psychological, structural and environmental aspect of discharged soldiers were surveyed at the cognitive level based on the soldiers waiting for the discharge from military service. As a result, it became clear that psychological advice or support and job training for the discharged soldiers who executed long-term service are urgent. In addition, an efficient system can control and maintain the system mentioned above.

This article examines the Stay of Enforcement of ICSID Arbitration Award. The effect of the stay is that the award is not subject to enforcement proceedings under Article 54 of the ICSID Convention pending the outcome of the annulment application. The annulment committee must decide the stay, unless the applicant sought the stay with the request for annulment, in which case the ICSID Secretary -General must grant it automatically. This automatic stay -which can only relate to the entire award-remains in force until the committee is constituted and issues a decision on the request for stay. ICSID committees have taken different positions on whether a stay of enforcement is exceptional or not. Some committees have held that because the ICSID Convention explicitly recognizes that the rights of the award creditor could be subject to a stay, stays are not exceptional. ICSID practice shows that most committees have rejected the proposition that the merits and prospects of the application for annulment should influence the committee's decision whether to grant a stay. In addition, ICSID practice regarding the specific circumstances that will justify a stay of enforcement is unclear, and committees have focused on different factors to decide whether to grant a stay such as prospect of prompt compliance with the ward, hardship to one of the parties, risk of non-recovery and irreparable harm to the award debtor. Also, ICSID practice shows that even though the Convention is silent on this issue, committees have generally held that they are empowered to condition the stay of enforcement on the granting of security by the requesting party.

The purpose of this study was to analyze impact absorption function of midsole in cushioned marathon shoes. The foot is made up of a complex interaction of bones, ligaments, and muscles. These structures help the foot alternate between being a mobile, flexible adaptor and a stable rigid lever. The foot is broken down into two functional parts, the forefoot and the rearfoot. Cushioned marathon shoes for high arches have generous cushioning for efficient and high-mileage runners. Cushioned marathon shoes are made for feet that have high arches or no excessive motion and don't roll inward or roll outward. This condition is known as underpronation. Especially, Cushioned marathon shoes are designed to reduce shock and generally have the softest (or most cushioned) midsoles and the least medial support. They are usually built on a semicurved or curved last to encourage foot motion, which is helpful for underpronators (who have rigid, immobile feet). Cushioning marathon shoes recommended for the high-arched runner, whose foot may roll outward (supinate) rather than the natural slight inward roll, or whose feet may be relatively rigid. Cushioning shoes emphasize flexibility and usually are built on a curved or semicurved last to encourage a normal motion of the foot. Cushioning shoes usually offer no medial (inner foot) support. Cushioned marathon shoes have the single-density midsole, which is stable and relatively firm for a cushioned shoe, stays the same. But the forefoot is more rounded, and the rearfoot now includes a new and supportive rearfoot cradle. A foam midsole, perhaps with layers of different densities, to provide cushioning and shock absorption. EVA (ethylene vinyl acetate) and PU (polyurethane), the materials from which these foams usually are made. EVA is slightly softer than PU. EVA and PU may be layered together in a shoe, or a shoe may have more than one density of EVA.

Recently the multi-kind, small-amount manufacturing system has been replacing the mass manufacturing system, and domestic machining inustry also is eager to absorb the new technology because of its high productivity and cost reduction. The optimization of the cutting condition has been a vital problem in the machining industry, which would help increase the productivity and raise the international competitiveness. It is intended in this study to investigate the machining costs per unit time which is essential to the analysis of the optimal cutting condition, to computer the cutting speed that lead to the minimum machining costs and the maximum production to suggest the cutting speed range that enables efficient speed cutting, and to review the machining economy in relation to cutting depth and feed. Also considered are the optimal cutting speed and prodution rated in rrelation with feed. It is found that the minimum-cost cutting speed increases and the efficient cutting speed range is reduced as machining cost per unit time increases since the cutting speed for maximum production remains almost constant. The machining cost is also lowered and the production rate increases as the feed increases, and the feed should be selected to satisfy the required surface roughness. The machining cost and production rate are hardly affected by the cutting depth if the cutting speed stays below 100m/min, however, they are subject to change at larger cutting depth and the high-efficient speed range also is restricted. It can be established an adaptive optimal cutting conditions can be established in workshop by the auto-selection progam for optimal operation. It is expected that this method for choosing the optimal cutting conditions might contribute to the improvement of the productivity and reduced the cost. It is highly recommended to prepare the optimal cutting conditionthus obtained for future use in the programing of G-function of CNC machines. If proper programs that automatically select the optimal cutting conditions should be developed, it would be helpful to the works being done in the machine shops and would result in noticeable production raise and cost reduction.

'Mu-acupuncture treatment(繆刺法)' and 'Geo-acupuncture treatment(巨刺法)' are the ways of taking acupuncture points on the sound side of a human body and not on the unsound side of a human body to treat disease, 'Mu-acupuncture treatment(繆刺法)' is applicable to 'Transverse meridian disease(絡脈病)', 'Geo-acupuncture treatment(巨刺法)' is applicable to 'Longitudinal meridian disease(經脈病)'. To diagnose a disease as transverse meridian disease or longitudinal meridian disease depends on 'Feeling pulse at the nine spots of three parts on a body for diagnosis (三部九候診)'. 'Mu-acupuncture treatment(繆刺法)' takes a 'Rak-acupuncture point(絡穴)' under a wrist and a ankle joint. The method of taking it, two ways, are 'Yu(痏)' and 'The treatment getting some blood(出血療法)'. 'Yu(?)' which is similar to 'Quick-getting acupuncture into and out (單刺法)' means the number of times doing acupuncture and is different from 'The treatment getting some blood (出血療法)' which is typically considered as 'Yu(?)'. Meanwhile, judging from the changes of the methods of feeling pulse for diagnosis and the symptoms of a certain disease, though it is a precondition that 'Biased-Gi(邪氣)' stays at 'The Large transverse meridian(大絡)' in 'The theory of Mu-acupuncture treatment(繆刺論)', it is hard to consider the symptoms of 'Transverse meridian disease(絡脈病)' described in 'The theory of Mu-acupuncture treatment(繆刺論)' as the pure symptoms of 'Transverse meridian disease(絡脈病)'.

Efficient power management plays a crucial role to strengthen competitiveness in the market of portable mobile commodities. This paper presents a proactive power management technique, called by Energy-Aware Scheduling policY (EASY), to exploit the sleep time information of running applications. Different from previous power management approaches focusing on power conservation in standby mode, the proposed scheme characterizes each application program's operational characteristic in active mode by observing how long the task stays in sleep state of CPU scheduler. Based on the measured sleep time, the proposed EASY speculates an adequate CPU clock frequency according to the current CPU workload and scales the frequency directly to the predicted one. Experimental results show that the proposed scheme reduces the power consumption by 10-30% on average compared to traditional DPM approach, with a minimal impact on the performance overhead.
