In the era of 2.0 web, blog has become the media that men can express themselves with fashion more actively and independently, as paying much attention to their personal appearance and cultivating an upscale lifestyle. They often create their fashion images in the virtual space where enables a free and creative operations of self-expression. The study aims to identify the types of men's ego-images represented on the personal fashion blogs based on the framework of analysis from the previous research (Suh, 2014), to build the base data for analyzing men's fashion style in $21^{st}$21st century that reflects changes in men's sexual images, and to verify the framework as comparing with the previous case study about the women blogs (Suh, 2014). The case studies conducted 5 men's personal blogs such as bryanboy, iamgala, little fashionisto, katelovesme, and stylentonic. The study results almost same types of women's ego-images as following. The imaginary ego-image is classified as narcissism, regression, identification, and virtuality, the social ego-image as symbolism of roles and others'desire, the real ego as primary instinct, practical reality, object a, jouissance and sexual perversion. The personal style of men shown on the fashion blogs appears as a significant factor to analyze male customers in the growing men's beauty and fashion market.

글로벌 CP들로 인해 인터넷의 트래픽이 급증하면서 망 투자비용을 분담하여야 한다는 주장이 업계에서 대두하였다. 이로 인해 망 중립성의 원칙이 접근성에서 비용 부담으로 논점이 크게 바뀌었다. 유료화된 트래픽의 우선처리가 각국에서 인정을 받았음에도 불구하고, 학계의 일부에서는 인터넷 공간에서 망 사용료 지불에 대한 부정적인 시각이 있었다. 그러나 업계에서는 사업자들 사이에 분쟁이 다수 발생하였고, 일부는 법정 다툼으로 비화되면서 법원의 판결에 관심이 쏠렸다. 법원이 망 중립성 하에서 유상성을 인정하기 시작하였고, 정부도 이에 대응하여 규제를 정비하는 등 우리나라는 빠르게 대처해 왔다. 그러나 여전히 서비스 안정에 초점을 맞추고 있으며, 직접적으로 망 이용대가의 지불을 규정한 규제는 아직 없다. 본 연구에서는 망 중립성에 대한 사업자간 분쟁 및 법원의 판결, 규제의 개선 사례를 분석하여 망 중립성의 변화를 고찰하였으며, 공유지의 비극 사례를 참고하여 수익자 부담의 원칙에 입각한 올바른 가격신호의 복원이 가장 중요한 해결책임을 제시하였다. CP의 망 사용료 지급도 그 방안의 하나이다.

Recently, with the increase in requirements for marine development, a marine urbanism is being visualized, with more and more huge-scale structures at the scope of the ocean space utilization. In particular, a pontoon-type structure has attracted attention, since The Floating Structures Association of Japan proposed a new concept as the most suitable one of floating airports. The Very Lage Floating Structure (VLFS) is considered a flexible structure, for a quite large length-to-breadth ratio and its geometrical flexibility. The main objective of this study is to makean exact and convenient prediction about the hydro-elastic response on very large offshore structures in waves. The numerical approach for the hydro-elastic responses is based on the combination of the three dimensional source distribution method and the dynamic response analysis method, which assumed a dividing pontoon type structure, as many rigid bodies connected elastic beam elements. The established hydo-elastic theory was applied to the radiation forces caused by motions of a whole structure, formulated using the global coordinate system, which has the origin at the center of the structure. However, in this paper, we took radiation forces, occurred by individual motions of floating bodies, into consideration. The calculated results show good agreement with the experimental and calculated results by Yago.

As contemporary art tends to diverge from its fixed genres and intends to appeal to the public, fashion comes to contribute to the contemporary art area, by playing an important part in the creation of artistic value of art work. Nowadays, it is not unusual to see fashion work shown in an art exhibition parallel with art work, since some artists adopt costumes as the medium of their work in order to explore various means of expression. The occurrence of philosophical, sociological theories concerning human body parallelled with the prevalence of the post-structuralist ideas and occurrence of various styles of artistic expressions of body encouraged active research and attracted social attention to body. With such background, fashion art was formed by a means of the integration of body and fashion in order to create extreme artistic expression. 1 intend to investigate a variety of trends in fashion art from the viewpoint of body space. This study developed criteria for fashion image in contemporary art. Those criteria are based on the dichotomy that divides body into inner aspects and outer aspects. According to the criteria, Firstly, the extension type of body shape includes enlargement and reduction as its sub-types. Secondly, the opening-closure type includes opening type and closure type as its sub-types. Thirdly, the intensity type categorizes clothes into uniqueness and hybridity. Dynamism type classifies fashion art into fixation and moving. The various expressions of clothes type are interpreted as a means by which we can criticize many phenomena of modern society, such as loss of humanity, isolation of individuals, loss of identity, commercialism, and materialism. In the latter period of modern society, the integration of the double-faced nature of body and spirit was attempted and popular fashion was introduced into art in order to express desire, death, gender, identity, and sexual pleasure.

한일 위안부 합의 이후 관객들의 관심 속에 소개된 두 편의 영화 <귀향>과 <눈길>은 모두 '위안부' 소녀들의 우정을 다루면서 살아 돌아 온자가 살아 돌아오지 못한 자를 고향과 저승으로 보내는 해원의 이야기를 다루었다. 기존의 '위안부' 서사들과는 다르게, 이 두 영화는 '위안부' 여성의 전장에서의 로맨스 플롯을 가지고 있지 않으며, 일종의 여성공간을 구축하고 있다. 현실에서의 새로운 젊은 여성의 존재는 개인적 우정의 이야기를 자매애의 공동체 차원으로 확장시킨다. 특히 <눈길>은 '위안부' 할머니가 새로운 후속 세대 여성에게 증언을 전수하는 증언작업의 가능성을 제시하고 있다. 영화적 현재에서는, 이렇듯 일본군 '위안부' 서사를 여성주의적으로 사고할 수 있는 가능성을 보여주고 있지만, 과거 식민지 시절의 재현은 많은 부분 기존의 가부장제적인 민족주의적 관점을 벗어나고 있지 못하다. 주인공들이 여전히 '순수하고 순결한' 조선소녀들로 설정되어 있다는 것이 대표적이다.

Hydrated asteroids get widespread attention for the evolution of water in the Solar System, especially thanks to the recent successes of the Hayabusa2 and OSIRIS-REx space missions. The target asteroids of these missions are believed to be fragments that have experienced aqueous alteration in their parent bodies [3]. Although hydrated asteroids have been studied well via spectroscopy, focusing on the 0.7 um or the 2.7 um absorption bands [2, 3, 4], polarimetric properties of these asteroids have rarely been investigated. In this study, we conducted a polarimetric observation of 18 C-complex main-belt asteroids with the 1.6-m Pirka telescope at the Nayoro Observatory of Hokkaido University, Japan. We used a polarimetric imaging mode of the Multi-Spectral Imager (MSI) with the standard Rc-band filter (the central wavelength at 0.64 um) [5]. As a result, we found that all of these hydrated asteroids indicate deep negative branches of their polarimetric profiles. Accordingly, the hydrated asteroids have the polarization minima (Pmin), whose values are significantly lower than any other taxonomic types of asteroids (including C-group asteroids). Because Pmin depends on albedo, particle size, and porosity of the surface materials [1], we suspect that hydrated asteroids are distinctive from other asteroids in terms of these physical properties. In this presentation, we introduce our polarimetric observation and findings. We discuss why hydrated asteroids indicate such low Pmin values, comparing Pmin with spectral features at 0.7 um and 2.7 um based on the observation results.

In compliance with environmental regulations at sea and the introduction of unmanned autonomous ships, electric propulsion ships are garnering significant attention. Induction machines used as propulsion electric motor (PEM) have maintenance advantages, but speed control is very complicated and difficult. One of the most commonly used techniques for speed control is DTC (direct torque control). DTC is simple in the reference frame transformation and the stator flux calculation. Meanwhile, two-level and three-level voltage source inverters (VSI) are predominantly used. The three-level VSI has more flexibility in voltage space vector selection compared to the two-level VSI. In this paper, speed is controlled using the DTC method based on the specifications of the PEM. The speed controller employs a PI controller with anti-windup functionality. In addition, the characteristics of the two-level VSI and three-level VSI are compared under identical conditions. It was confirmed through simulation that proper control of speed and torque has been achieved. In particular, the torque ripple was small and control was possible with a low DC voltage at low speed in the three-level VSI. The study confirmed that the application of DTC, using a three-level VSI, contributes to enhancing the system's response performance.

Due to droughts and water shortages causing severe damage to crops and other vegetations, much attention has been given to efficient irrigation for upland farming. However, little information has been known to measure soil moisture levels in a field scale and apply their spatial variability for proper irrigation scheduling. This study aimed to characterize the spatial variability and temporal stability of soil water contents at depths of 10 cm, 20 cm and 30 cm on flat (loamy soil) and hill-slope fields (silt-loamy soil). Field monitoring of soil moisture contents was used for variogram analysis using GS+ software. Kriging produced from the structural parameters of variogram was applied for the means of spatial prediction. The overall results showed that the surface soil moisture presented a strong spatial dependence at the sampling time and space in the field scale. The coefficient variation (CV) of soil moisture was within 7.0~31.3 % in a flat field and 8.3~39.4 % in a hill-slope field, which was noticeable in the dry season rather than the rainy season. The drought assessment analysis showed that only one day (Dec. 21st) was determined as dry (20.4 % and 24.5 % for flat and hill-slope fields, respectively). In contrary to a hill-slope field where the full irrigation was necessary, the centralized irrigation scheme was appeared to be more effective for a flat field based on the spatial variability of soil moisture contents. The findings of this study clearly showed that the geostatistical analysis of soil moisture contents greatly contributes to proper irrigation scheduling for water-efficient irrigation with maximal crop productivity and environmental benefits.
