KINAC (Korea Institute of Nuclear Non-proliferation and Control) is entrusted with the NSSC (Nuclear Safety And Security Commission) to conduct threat assessments for nuclear facilities. As part of the threat assessment, DBT (Design Basis Threat) must be established every three years, and a threat assessment report must be developed for DBT establishment. This paper suggests a method for collecting and analyzing cyber threat information for the development of a cyber security threat assessment report. Recently, cyber threats not only in the IT (Information Technology) field but also in the ICS (Industrial Control System) field are rapidly increasing. As cyber threats increase, threat information including related attack techniques is also increasing. Although KINAC is conducting a threat assessment on cyber security at nuclear facilities, it cannot collect and analyze all cyber threat information. Therefore, it is necessary to determine a reliable source of threat information for threat assessment, and establish a strategy for collecting and analyzing threat information for DBT establishment. The first method for collecting and analyzing threat information is to first collect threat information on industrial fields with high similarity to nuclear facilities. Most of the disclosed cyber threat information is in the IT field, and most of this information is not suitable for closed-network nuclear facilities. Therefore, it is necessary to first collect and analyze threat information on facilities that use networks similar to nuclear facilities such as energy and financial sector. The second method is to analyze the attack technique for the collected threat information. The biggest factor in DBT reset is whether there is a new threat and how much it has increased compared to the existing threat. Therefore, it is necessary to analyze which attack technique was used in the collected threat information, and as part of the analysis, a cyber attack analysis model such as a kill chain can be used. The last method is to collect and manage the disclosed vulnerability information. In order to manage vulnerabilities, it is necessary to analyze what assets are in the nuclear facility first. By matching the reported vulnerability with the CDA (Critical Digital Asset) in the facility, it is possible to analyze whether the CDA can be affected by a cyber attack.As cyber threats continue to increase, it is necessary to analyze threat cases of similar facilities, attack techniques using attack models, and vulnerability analysis through asset identification in order to develop a threat assessments report.

The purpose of this study is to analyze the expressive elements and techniques of graffiti appearing in the Moschino collection by Jeremy Scott. A theoretical examination of graffiti art and Moschino’s creative designer Jeremy Scott was conducted using previous studies and publications. Accordingly, keywords about the expressive elements and techniques of graffiti and Moschino were identified, as follows: expressive elements of ‘message (slogan)’, ‘symbolized letters or forms’, ‘logo and brand symbol’, ‘graffiti (scribbles)’, ‘child-like elements’, ‘daily element’s and expressive techniques of ‘using primary colors (color contrast)’, ‘deformation’, ‘distortion’, ‘exaggeration’, ‘illusion (trompe l'oeil)’, ‘collage (repetition)’, ‘simplification (flattening)’, and ‘borrowing heterogeneous objects’. These keywords were then used to analyze Moschino’s collection, comprising seven years of Moschino’s collection photographs officially recorded in the fashion magazine Vogue, ranging from the 2014 F/W to 2020 F/W collections. A total of 761 photos were initially collected, from which 561 were selected by the researcher. Expressive characteristics of graffiti in Moschino’s collection were analyzed, and identified in the following categories: ‘child-like playfulness’, ‘commercial satire’, ‘using daily elements’, and ‘borrowing non-representative techniques’. Accordingly, it was confirmed that expressive characteristics of graffiti were found in the Moschino collection by Jeremy Scott. This study anticipates the possibility of various interpretations from which fashion that communicates closely with contemporary art can be understood.

The Republic of Korea is expected to participate in the denuclearization verification activities by the International Atomic Energy Agency (IAEA) in case any neighboring countries declared denuclearization. In this study, samples for the verification of nuclear activities in undeclared areas were selected for the denuclearization of neighboring countries, and the appropriateness of the procedures was considered. If a country with nuclear weapons declares denuclearization, it must be accompanied by the IAEA’s verification regarding nuclear materials and weapons in the declared and undeclared areas. The analysis of the process samples or on-site environmental samples and the verification of undeclared nuclear facilities and materials aid in uncovering any evidence of concealment of nuclear activity in undeclared areas. Therefore, a methodology was established for effective sampling and analysis in accordance with proper procedures. Preparations for sampling in undeclared areas were undertaken for various potential scenarios, such as, the establishment of zones according to radiation dose, methods of supplying electricity, wireless communication networks, targets of sampling according to characteristics of nuclides, manned sampling method, and unmanned sampling method. Through this, procedures were established for pre- and post-site settings in preparation for hazards and limiting factors at nuclear inspection sites.

1991년 작품 Seeing Things를 『사물보기』 혹은 『환영보기』로, 1995년 노벨문학상 직후의 작품인 The Spirit Level을 『기포 수준기』 혹은 『영혼 측정』으로 변역할 수 있는 이유는 작가가 물질세계로부터 영혼세계로의 건너가기를 시도하고 있기 때문이다. 그런데 작가의 이 같은 시도는 부모님의 죽음이 가장 큰 동기였다고 생각한다. 작가는 그에게 영향을 끼친 부모와 지인들의 추억을 그들이 남긴 유품이나 업적과 함께 불멸의 유골 단지인 자신의 시에 보존시키려 한다. 아울러 『영혼 측정』의 많은 시들이 애가나 소네트 그리고 패스티쉬 형식의 헌정 시로 쓰인 점은 필자로 하여금 시인이 다가오 는 자신의 죽음을 준비하고 있다는 생각을 갖게 한다. 이 논문의 목적은 위의 추론을 이 시집 전체의 시를 읽어 증명할 뿐 아니라 수수께끼 같이 어려운 후기 시에 우리 말 번역과 해설을 시도하는 것이다.

PURPOSES : There are generally various driving behaviors in toll collection areas, including lane changing, merging and diverging, and other behaviors. Because of these behaviors, accident risk and traffic congestion may occur. To mitigate these problems, multi-lane electronic toll collection systems have been developed with a high-speed limit of 80 km/h. This study was conducted to investigate travel speed changes and effects through multi-lane electronic toll collection systems with a high-speed limit. METHODS : Traffic simulations were conducted using VISSIM. Before conducting simulations, driving behavior around the toll collection areas was observed, and field data were collected based on drones for peak and non-peak hours. In addition, safety effect evaluations were conducted based on conflict analyses using the SSAM software. RESULTS : Through multi-lane electronic toll collection systems with a high-speed limit, the travel speed on the toll collection area was increased, and traffic operational efficiencies were identified. However, different speed variations were produced as observation locations in toll collection areas. Speed variations were mitigated at most locations except the area within the tollbooth because of the high speed limit for multi-lane electronic tollbooth. CONCLUSIONS : It was important to manage lane-changing activities, and this may influence traffic operational effects. Safety effects were also identified through conflict analyses.

PURPOSES : This study introduces the use of instantaneous speed collected by in-vehicle sensing devices for space mean speed and time mean speed estimation. METHODS : Using probe vehicles’ instantaneous speed data and GPS location at each designated time interval enables analysts to calculate the link-based space mean speed and time mean speed for a certain time-space domain directly. This study proves the equations mathematically and compares the results of time mean speed using Wardrop’s equation and section average speed by trips. RESULTS : This study introduces the concept of link-based average speed using both time mean and space mean speed definitions. First, an unbiased space mean speed was explained for a roadway section can be calculated from high-resolution vehicle trajectory data without necessarily continuously tracking a vehicle. Second, this study proves that the average section speed by occupancy resulted in identical values to the true space mean speed formulation by Wardrop. In addition, the average section speed by trip was nearly identical to the time mean speed. CONCLUSIONS : Each section on a signalized intersection corridor yielded various speed distributions whose parameters varied as measurements were taken closer to the intersection proper. By exploring the space mean speed with speed distribution, the intersection impact area can be defined more accurately.

In this study, the artistic background and formative nature of representative 19th century realist artists Gustave Courbet and Honoré Daumier were analyzed and applied in a fashion context. By displaying representational desires (necessary adhesions of man and society) in their work, they became characteristic matrixes of critical realism and to perceive critical realism. The purpose of the study was to apply the characteristics of critical realism to the contemporary fashion collections of Alexander McQueen. Research was conducted to analyze the characteristics that appear in the field of fashion and to review methods of expression and internal aesthetics displayed through various aspects of fashion design. Characteristics of critical realism were analyzed by researching the formativeness and periodical background of the paintings of Courbet and Daumier. Based on these characteristics, analysis was conducted to identify critical realism in the fashion collections of Alexander McQueen. Data and scope included fashion information sites, internet photo data, and video material. Critical realist characteristics were categorized into five types as follows: ‘The proper borrowing of extremely realistic subjects signifies’, ‘satirical reconstruction and narrative composition’, ‘antipathetic distortions and abject representations’, ‘critical reproductions based on technology’, and ‘the maximization of ambivalent sexuality’. It was concluded that the characteristics of critical realism (recognized by the common formation of Courbet and Daumier) also appeared in Alexander McQueen's fashion collection but were inherited in a form that transcended pictorial expression due to the overall difference in use of visual arts.

The purpose of this study is to provide basic data to assist students and industrial designers in fashion by examining the trend of designing women’s wear with the SCAMPER method. In the research, the seven types of SCAMPER methods for fashion design were classified based on the previous studies. From 2010 S/S to 2020 S/S, data from 5,149 photographs were collected through overlapping checks and classified by SCAMPER method type. Data analysis was performed using SPSS 25.0 for frequency analysis. As a result, in the SCAMPER “combine” method, more than two items were combined, or structural details were combined with items. In the most applied “adapt” method was involved imitating similar images, or natural forms, or other objects. The “modify” method was applied by changing the shape of some details in basic fashion items. The “magnify” method was applied by enlarging, elongating, or elevating some details of fashion items. The “minify” method was applied by minimizing, shortening, or lowering some details of basic fashion. The method of “put to other use” was expressed throughout the clothing by using non-fabric or trimmings such as metal, beads, and strings. The “rearrange” method was applied by repositioning the top and bottom, front and back, or outside and inside in fashion items and in details. The “reverse” method was applied by reversing the style of fashion, mix-and-match fabric, or switching the gender of the fashion items.

In this study, acoustic and viscosity data are collected in real time during the ball milling process and analyzed for correlation. After fast Fourier transformation (FFT) of the acoustic data, changes in the signals are observed as a function of the milling time. To analyze this quantitatively, the frequency band is divided into 1 kHz ranges to obtain an integral value. The integrated values in the 2–3 kHz range of the frequency band decrease linearly, confirming that they have a high correlation with changes in viscosity. The experiment is repeated four times to ensure the reproducibility of the data. The results of this study show that it is possible to estimate changes in slurry properties, such as viscosity and particle size, during the ball milling process using an acoustic signal.

The conversation analysis approach of using audio and video recordings of naturally occurring conversation contrasts with other methods of collecting data in the social and cognitive sciences. This paper intends to describe the ways in which conversation analysts collect their data suitable for analysis, including the steps involved in preparing to record, the recording of naturally occurring social interaction, and also the processing of recordings after they have been made. Before actually making the recordings, researchers must first choose what type of conversation they will collect and what device to use. Researchers also need to obtain consent for recording from the participants in a conversation analytic study. While making the recordings, researchers must figure out many practical issues such as who, when, how, what, how much, and where to record. After recording, researchers need to store data in audio or video formats. Researchers also archive it, using codes for identification that facilitate later finding, quoting and retrieving of any file. This paper focuses on these choices as they are made before, during, and after recordings and places specific emphasis on the effects these choices have on the recordings. It also illuminates how these techniques are closely related to the methodological and theoretical assumptions of the conversation analysis approach.

This study was conducted to examine the oocyte recovery efficiency through having an OPU session once and twice a week. Also, the oocyte recovery efficiency was examined by using OPU after two and three months of rest period. Six cows were used for oocytes collection and were randomly divided into two groups. In experiment 1, OPU sessions were conducted once and twice a week to collect oocytes. The collected oocytes between once and twice OPU groups were classified into four groups (grade 1, 2, 3 and 4) according to the quality of cumulus cells and ooplasm. Based on the result, the percentage of collected oocytes per aspirated follicle number was similar between once and twice OPU session groups (65.5 ± 1.9 and 68.7 ± 1.4 vs.). However, the percentage of grade 1 oocytes from the twice OPU session group was significantly high compared with that of the once a week OPU session group (25.3 ± 0.9 and 32.5 ± 1.2% vs. once and twice session group, respectively, p < 0.05). In experiment 2, the group with three months of rest period tended to have a high percentage of collected oocyte compared with the group with two months of rest period (64.6 and 70.9% vs. 2 and 3 months rest group, respectively, p = 0.62). The percentage of grade 4 in the group with three months of rest period was significantly low compared with the group with two months of rest period group (27.3 and 36.5% vs. two and three months rest group, respectively, p = 0.05). In conclusion, twice a week OPU session is suitable for collection of high quality oocytes by using OPU, and three months of rest period is needed for the recovery of oocyte quality of a donor cow.
